    DESCRIPTION

    Fixing device for a part of a vehicle

     5
    OBJECT OF THE INVENTION

    The object of the present patent application is a fixing device for a part of a vehicle according to claim 1, which incorporates notable innovations and advantages.
     10

    BACKGROUND OF THE INVENTION

    At present, various fixing devices for the parts of a vehicle are known. It is observed that when said type of fixing is to the body, this is usually done with an additional component.

    On the other hand, it is known in the state of the art, as reflected in document CN201116562, a fixing element for fixing decorators and vehicle lamps. It is composed of an elastic nut and a fixing unit. The elastic nut 20 is U-shaped. One end of the elastic nut is provided with a locking element, which is extended outwards. The device does not have great mounting versatility, nor does it seem applicable to a multitude of configurations.

    It is on the other hand known in the state of the art, as reflected in document US6416125, a mounting device for a headrest support assembly with a backrest frame. The assembly includes components that are injection molded on site on extended flanges of a connector link. It does not seem, however, a generic solution extrapolable to the assembly of various parts on the body of the vehicle. 30

    Thus, it is seen that there is still a need to have a fixing device for a part of a vehicle, preferably to the body, in which the provisioning of an additional mounting component by the operator is not necessary, such that Your assembly process is optimized. This would eliminate the action of searching for the additional mounting component, as well as facilitating the operation of placing said element in the bolt or similar element.


    DESCRIPTION OF THE INVENTION 5

    The present invention proposes to integrate the fastenings of a main part thereto, preferably through plastic bands. Subsequently, the entire assembly is injected into the same mold in which said main part is manufactured.
     10
    In more detail, the main piece is usually an internal finishing piece. Normally, it is a large part whose function is to improve the interior finishes or coatings of the vehicle, hiding areas and / or components of the vehicle so that they are not accessible by the user. These main internal finishing parts are positioned on the body by means of through bolts through holes of said main parts. In addition, said bolts are also used for fixing said plastic parts.

    The present invention proposes that said main part preferably obtained by injection, incorporates a band, hinge, film or a flexible plastic zone that allows the fixing element to be connected, which allows the main part to be fixed to the body, with the workpiece plastic or internal lining, or main piece. Said flexible plastic zone must have small dimensions, especially in its thickness, in order to enable its flexibility precisely.
     25
    Thus, and more specifically, the fixing device for a part of a vehicle, where the part is made of plastic material, obtained through an injection process, and where the part comprises a main body, comprises a fixing element and a connecting element of said fixing element to the main body, wherein the main body and the fixing device are obtained from the same injection process, said connecting element 30 being elongated. Said elongated configuration of the connecting element is what enables the flexibility properties necessary to obtain the advantages derived from the present invention. It is important to comment that the material that forms the part of the vehicle is a plastic that, under conditions of use, provides the piece with rigid and stress-resistant properties. Due to the single injection of the part of the present invention, the material that forms said part, the fixing element and the connecting element is the same. Thus, the flexibility properties that characterize the connecting element are granted by its geometry, which is particularly elongated, allowing its easy handling and the relative movement of the fixing element with respect to the vehicle part. Other additional derived advantages would be: 5
    • Impossibility for the operator to omit the placement of the fixing element during the assembly of the main part, as these fixing elements are integrated, and being very close to the assembly area.
    • Impossibility of placing an incorrect fixing element during the assembly of the main part, since the correct fixing elements adjacent to its area of use are integrated.
    • Cost savings of independent fasteners.
    • Saving of assembly time.

    In a preferred embodiment of the invention, the connecting element is elongated such that its length is greater than a length of the fixing element. In this way, the connecting element provides sufficient clearance, allowing to reorient and comfortably position the fixing element such that it can be inserted and mounted in the place intended for it.

    More particularly, the joint element has substantially a shape of a band such that its thickness is substantially less than a width of the joint element. The thickness of the connecting element means the dimension or dimension in the direction of demoulding or opening of the mold from which the main part is obtained. Consequently, in a plane perpendicular to the demolding direction, the connecting element comprises a length substantially greater than its width. Said band-shaped configuration 25 exhibits the property of flexibility mainly by virtue of its dimensions, that is to say, with a very small thickness with respect to the width and length of the connecting element, this even in the case that the constituent plastic material does not present special benefits in terms of flexibility.
     30
    According to another aspect of the invention, the injection process comprises a single injection stage in the same injection mold. That is, the entire component of the main part plus the fixing device are obtained from the same injection process, avoiding additional stages such as an over-injection or a bi-injection. Thus, the production of the complete component object of the present injection is carried out quickly and in a single stage, facilitating and simplifying its production process.

    Advantageously, the connecting element and the fixing element are substantially perpendicular to the demoulding direction of the injection mold. In this way the piece 5 can be demoulded without the need to design additional slides in the mold, which results in its simplicity and, therefore, in a lower cost of the injection machine. To specify that both the connecting element and the fixing element must be substantially in the same plane, named as the demoulding plane.
     10
    Advantageously, the part is an internal component of the vehicle, where the part is seen from the interior of the vehicle. As mentioned above, the vehicle part is, in a preferred embodiment, a large component of the interior of the vehicle. This part is positioned and fixed to the vehicle body by bolts welded on the body. These bolts pass through the piece through holes 15 specially designed for this. The fixing element will allow to fix the interior part of the vehicle to the body bolts. Alternatively, the fixing element is used for the coupling of the part with respect to another part or component of the vehicle, different from the body of the vehicle, like other plastic parts.
     twenty
    Thus, and in a preferred embodiment of the invention, the fixing element is a plug, so that said fixing element is concretized with a type of component of proven properties and reliability in the field of the automotive industry. Thus, the fixing element is a thread or a plug intended to fix the interior part of the vehicle to the body bolt. 25

    Advantageously, the fixing element is a screw or an expandable block or a pin, in order to close possible leaks of fluids, or unwanted transfers thereof between internal compartments of the vehicle, being able to establish sealed areas if so desired. Thus, the fixing element will be included in the interior part of the vehicle, in an area 30 very close to the hole to be covered. During the assembly and assembly process, it will be very convenient for the user to bring the plug closer to the hole, preventing him from forgetting it or locating a wrong plug.

    According to another aspect of the invention, the connecting element is capable of bending so that the fixing element can rotate towards the joining element at least 180 ° with respect to its resting position. By flecting it is meant to fold over the connecting element, that is, rotate on a plane that cuts the surface of the band perpendicularly and longitudinally. The rest position is understood as the natural position based on the balance of 5 forces between the weight of the connecting element plus that of the fixing element, with the resistance to bending, for a specific orientation of the main part. Consequently, the geometry of the connecting element allows to move from a resting situation in which the connecting element and the fixing element are substantially in the same plane, the fixing element being an extension of the connecting element, to 10 a second position in which the fixing element has rotated 180 ° without breaking the connecting element. In this way and by rotating at least 180 °, a plug-in fixing element can be oriented and placed in the proper position for assembly.
     fifteen
    According to yet another aspect of the invention, the connecting element is capable of bending so that the fixing element can rotate towards the connecting element at least 270 ° with respect to its resting position. Again by flecting it is meant to fold over the connecting element, that is, rotate on a plane that cuts the surface of the band perpendicularly and longitudinally. Also in this case, the rest position is understood as the natural position based on the balance of forces between the weight of the connecting element plus that of the fixing element, with the resistance to bending, for a specific orientation of the main part. In this way and by rotating at least 270 °, a screw-type fixing element, or expandable block, or pin, can be oriented and placed in the proper position for insertion into the corresponding hole and its assembly. 25

    Consequently, depending on the type of fixing element implemented in the fixing device, the connecting element is designed according to one or other geometric characteristics, which allow greater or lesser possibilities of bending on itself.
     30
    According to an alternative embodiment, the connecting element that joins the fixing element to the main body is designed to break when the fixing element passes from the rest position to the use position. In this way, the advantages are maintained that the operator who assembles the fixing element has it at the assembly point, without requiring additional logistics, or possible errors in positioning ... 35 causing breakage in the assembly phase, when the fixing element passes to the position of use.

    Additionally, the invention comprises a vehicle part comprising the fixing device, as described above. 5

    The attached drawings show, by way of non-limiting example, a fixing device for a part of a vehicle, constituted according to the invention. Other features and advantages of said fixing device for a part of a vehicle, object of the present invention, will be apparent from the description of a preferred but not exclusive embodiment 10, which is illustrated by way of non-limiting example in the accompanying drawings, in which:

    DESCRIPTION OF A PREFERRED EMBODIMENT

    In view of the aforementioned figures and, according to the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below.
    Thus, as can be seen in Figures 2, 4 and 6, the fixing device 3 for a part 1 of a vehicle, where the part 1 is made of plastic material, obtained through an injection process, where the part 1 it comprises a main body 2, it comprises a fixing element 31 and a connecting element 32 of said fixing element 31 to the main body 2, wherein the main body 2 and the fixing device 3 are obtained from the same injection process, and where the connecting element 32 is elongated.

    More particularly, as seen in Figures 2, 4 and 6, the connecting element 32 is elongated 10 such that its length is greater than a length of the fixing element 31.

    According to a preferred embodiment of the invention, as seen in Figures 3 and 4, the connecting element 32 has substantially a band shape such that its thickness is substantially less than a width of the joining element 32. 15

    Thus, an interior part 1 of a vehicle comprising at least one fixing device 3 is shown in FIG. 1. Specifically, it is a footrest of a vehicle that covers the lower lateral area of the vehicle. This part 1 is positioned with respect to the vehicle and fixed to it by holes pierced by body bolts. These 20 holes can be seen in greater detail in Figure 2, these holes being in unseen areas when the vehicle is assembled. To facilitate the assembly process and the logistics required during assembly, part 1 incorporates the required fixing element 31, said fixing element 31 being connected to the part 1 by means of a connecting element 32. The geometric characteristics of the joining element 32 described together with the 25 properties of the material allow a comfortable movement of the fixing element 31 with respect to the part 1, facilitating handling tasks by an operator of the assembly line.

    It should be mentioned that, as can be interpreted from the figures, the injection process 30 comprises a single injection stage in the same injection mold.

    More specifically, as seen in Figures 3 and 4, the connecting element 32 and the fixing element 31 are substantially perpendicular to the demoulding direction of the injection mold. With all this, the costs of the production process of the piece 1 are not increased and, on the other hand, the assembly times are reduced considerably, as well as the transport and logistics costs by having a piece 1 that already integrates the at least a fixing means 31. The manufacturing complexity is also reduced, since both the piece 1 and the fixing element 31 are obtained from the same mold, obtaining the whole assembly without additional steps or slides. 5

    According to another aspect of the invention, as seen in Figure 1, part 1 is an internal component of the vehicle, where part 1 is seen from the interior of the vehicle.

    More specifically, as seen in Figures 3 and 5, the fixing element 31 is a plug. In order to fix the bolts and avoid a relative movement of the part 1 with respect to the body, a fixing element 31 is required as shown in Figure 3. This fixing element 31 is a plug with the less a tooth that prevents the movement of removal of the plug in the bolt once this fixing element 31 is in its use position. fifteen

    Alternatively, as seen in Figures 4 and 6, the fixing element 31 is a screw or an expandable plug or pin. Likewise, in order to position the part 1 with respect to the body of the vehicle, an expandable pin or stud will be passed through a hole in the part 1 and through a hole in the body. It can also be used as a sealing element to close an opening or hole in the vehicle body.

    According to a preferred embodiment of the invention, as seen in Figure 5, the connecting element 32 is capable of bending so that the fixing element 31 can rotate towards the connecting element 32 at least 180 ° with respect to its position of repose. 25 Specifically, when the connecting element 32 is in the form of a plug, the operator must introduce a 180 ° turn in order to rotate the fixing element 31 from its resting position or resulting injection position (perpendicular to the demoulding direction ) to the position of use. The connecting element 32 makes it possible to complete the necessary path for the correct assembly of the fixing element 31. 30

    According to another preferred embodiment of the invention, as seen in Figure 6, the connecting element 32 is capable of bending so that the fixing element 31 can rotate towards the connecting element 32 at least 270 ° with respect to its position of repose.
    Specifically, when the connecting element 32 is in the form of a screw, expandable plug or pin, the operator must introduce a rotation of 270 ° in order to rotate the fixing element 31 from its resting position or resulting injection position (perpendicular to the demoulding direction) to the position of use. The connecting element 32 makes it possible to complete the necessary path for the correct assembly of the fixing element 31. 5

    It is also an object of the present invention, as can be seen in Figures 1 and 2, a vehicle part 1 comprising the fixing device 3 according to claim 1.

    The details, shapes, dimensions and other accessory elements, as well as the 10 components used in the implementation of the fixing device for a part of a vehicle may be conveniently replaced by others that are technically equivalent, and do not depart from essentiality of the invention or of the scope defined by the claims that are included after the following list.
