    DETAILED DESCRIPTION OF THE INVENTION Referring now to Figure 1, the reference number 10 generally designates a vehicle door assembly. The vehicle door assembly 10 can be installed as a driver side door, passenger side door, or passenger rear doors. In addition, although here designated by a vehicle door 11 which is included in the assembly 10, the vehicle door assembly 10 can be installed as a rear door assembly of the vehicle, such as a tailgate. , a trunk or a tailgate. A vehicle lock assembly 12 is operatively coupled to the vehicle door 11 to hold the door (or the tailgate, trunk, tailgate, etc.) in a closed position and to unlock the vehicle door to allow a user to move the vehicle door 11 to an open position. The vehicle lock assembly 12 is an electromechanical lock assembly in some embodiments, thereby providing opening assistance to a user.
    In the embodiments described here, the vehicle door 11 does not have a door handle outside of the vehicle door 11. By not including a door handle, the door can be more aesthetic and / or offers an additional security measure which prevents unauthorized access to the vehicle. A keyless entry mechanism or device is used to initiate a door opening procedure. For example, a keychain, mobile device app, keyboard or similar keyless entry mechanism can be used to operate the door opening. In particular, the vehicle lock assembly 12 is actuated to allow the door to be opened.
    A door opening mechanism 14 which is operatively coupled to the vehicle door 11 operates in conjunction with the vehicle lock assembly 12. In the illustrated embodiment, the door opening mechanism 14 is disposed below the vehicle lock assembly 12, but it should be noted that the door opening mechanism 14 may be located adjacent to the vehicle lock assembly 12 in an adjacent alternative configuration or spaced therefrom this. The door opening mechanism 14 actuates the opening of the vehicle door 11 by urging (for example by pushing) the vehicle door 11 away from a vehicle body surface 16 (Figures 3 and 4) as can be find out from this disclosure. The vehicle body surface 16 can be any suitable surface relative to which the vehicle door 11 can pivot, or alternatively, move away from eHe, to move the vehicle door 11 from the closed position to a partially open position. In some embodiments, the vehicle body surface is a body pillar, such as a center pillar or a rear pillar, for example, but it should be noted that other suitable surfaces can be used to stress the door. away from the closed position.
    As used here, a closed position of the vehicle door 11 refers to a completely closed position of the vehicle door 11, so that the door is not ajar relative to the vehicle body. A partially open position of the vehicle door 11 refers to a partially open position of the door relative to the vehicle body, the door being spaced from the vehicle body to an extent sufficient to allow a user to insert his fingers between the internal panel of the vehicle door 11 and the vehicle body so as to allow the movement of the vehicle door 11 away from the partially open position to a fully open position of the vehicle door. The fully open position refers to a position that allows a user to enter the vehicle. In some embodiments, the partially open position is defined by a space between the vehicle door 11 and the vehicle body surface 16 of less than about 50 millimeters. In certain embodiments, the partially open position is defined by a space between the vehicle door 11 and the vehicle body surface 16 of between approximately 10 millimeters and approximately 40 millimeters.
    Referring now to Figures 2 to 4, the door opening mechanism 14 is illustrated in more detail. The door opening mechanism 14 is an electromechanical assembly which comprises a gear arrangement 18 driven by an electric motor 20. In the illustrated embodiment, the gear arrangement 18 comprises a worm screw 22 and a gear worm gear 24 in engagement by meshing. The worm 22 is driven by the electric motor 20 when the keyless entry mechanism is initiated. The worm gear 24 is coupled to a pinion 26 which is engaged by engagement with a rack 28 of a bias structure 30. Due to the engagement relationships described above, the bias structure 30 can perform a precisely controlled translation between a first position (Figure 3) and a second position (Figure 4). The first position corresponds to the closed position of the vehicle door 11 and the second position corresponds to the partially open position of the vehicle door 11.
    As shown in Figures 3 and 4, one end 32 of the biasing structure 30 is spaced from the vehicle body surface 16 in the first position (Figure 3) and extends due to the engagement by meshing of the rack 28 and the pinion 26 until the end 32 of the stress structure 30 engages with the vehicle body surface 16. The translation of the stress structure 30 continues until that the biasing structure 30 is in the second position (FIG. 4), which makes it possible to place the vehicle door 11 in a predefined ajar position which corresponds to the partially open position of the vehicle door 11. The movement of the first position until the end 32 engages the vehicle body surface 16 includes the translation of the end 32 through an opening 34 of an interior panel 36 of the vehicle door 11 in certain modes of achievement. Although it is described above and illustrated in Figure 3 as having a gap between the end 32 of the biasing structure 30 and the surface of the vehicle body 16, it is envisaged that the end 32 will abut against the vehicle body surface 16 in the first position.
    In the second position (Figure 4) of the biasing structure 30, the partially open position of the vehicle door 11 is maintained by contact between the end 32 of the biasing structure 30 and the body surface of vehicle 16. This position allows a user to insert his fingers into the space provided by the partially open position and prevents the vehicle door 11 from closing on the user's fingers. However, prevention of unexpected movement of the vehicle door 11 in the other direction is also desired and accomplished by the embodiments described here. In particular, the embodiments described herein prevent the vehicle door 11 from moving, perhaps quickly, from the partially open position to the fully open position, thereby reducing the likelihood of user injury or damage. the vehicle door 11 or surrounding objects.
    Referring now to Figures 5 and 6, an embodiment of a retaining structure 40 of the door opening mechanism 14 is illustrated. The door opening mechanism 40 is shown in the closed position in Figure 5 and in the partially open position in Figure 6. The retaining structure 40 is disposed near the part of the biasing structure 30 which s engages with the vehicle body surface 16. In particular, the retaining structure 40 is disposed on the end 32 of the biasing structure 30 in certain embodiments. The retaining structure 40 retains the vehicle door 11 in the partially open position to prevent the vehicle door 11 from moving to the fully open position.
    In the illustrated embodiment, the retaining structure 40 is a magnet disposed on the end 32 of the biasing structure 30, the magnet being able to engage with the vehicle body surface 16 to exert a force magnetic to retain the vehicle door 11 in the partially open position. The magnetic force resists forces applied to the vehicle door 11 which are less than a predetermined force. The predetermined force is adjusted based on the expected forces applied to the vehicle door 11 due to wind and gravity, for example. In some embodiments, the predetermined force varies between about 40 Newtons and about 60 Newtons. In one embodiment, the predetermined force is about 50 Newtons. However, a magnet as a door retaining structure can provide an even greater force if the magnetic field is regulated by the addition of a sensor which is described below.
    In some embodiments, the magnetic force is maintained through the use of an electromagnetic mechanism or the like. The user must then interact with a user interface to stop the magnetic force, the user interface being in functional communication with the biasing structure 30 to stop the application of the magnetic force in order to allow a user to move the door of vehicle 11 to the fully open position. In some embodiments, the user interface is a sensor or the like. The sensor can be located near an input area of the vehicle door 11 to allow the user to easily contact the sensor and complete the door opening process continuously. For embodiments requiring the stopping of the magnetic force, predetermined forces greater than those discussed above can be used to further protect against the uncontrolled opening of the vehicle door 11. For example, in embodiments requiring a sensor to deactivate the magnetic force, the predetermined force is greater than about 100 Newtons to provide additional attachment of the vehicle door 11. Alternatively, in some embodiments, a user can manually overcome the magnetic force by exceeding the force predetermined to move the vehicle door 11 away from the partially open position and toward the fully open position.
    Referring now to Figures 7 and 8, an embodiment of a retaining structure 140 of the door opening mechanism 14 is illustrated. The door opening mechanism 140 is shown in the closed position in Figure 7 and in the partially open position in Figure 8. The retaining structure 140 is disposed near the portion of the biasing structure 30 that s engages with the vehicle body surface 16. In particular, the retaining structure 140 is disposed on the end 32 of the biasing structure 30 in certain embodiments. The retaining structure 140 retains the vehicle door 11 in the partially open position to prevent the vehicle door 11 from moving to the fully open position.
    In the illustrated embodiment, the retaining structure 140 is a hook 142 disposed on the end 32 of the biasing structure 30, the hook 142 being able to engage with a toothed part 144 of the surface of the vehicle body 16 for retain the vehicle door 11 in the partially open position. The hook 142 is resiliently biased by a spring 146 so as to resist the forces applied to the vehicle door 11 which are less than a predetermined force. The predetermined force is fixed as a function of the anticipated forces that can be applied to the vehicle door 11 due to the wind and gravity, for example. In some embodiments, the predetermined force varies between about 40 Newtons and about 60 Newtons. In one embodiment, the predetermined force is about 50 Newtons.
    The interaction between the user and the vehicle door 11 deactivates the retaining structure 140 by retracting the hook 142 during the application of the manual force which exceeds the predetermined force. The predetermined force can be adjusted to any desired force by changing the stress characteristics of the spring. In addition, various procedures for closing the vehicle door 11 can be facilitated by the retaining structure 140, such as moving the vehicle door 11 from an open position to the closed position. For example, when the vehicle door 11 is in the partially open position, the door opening mechanism 14 can close the door (partially or completely) in the absence of user action.
    Advantageously, the embodiments described here allow the vehicle doors without handles to be retained in a partially open position until a user interacts with the vehicle door. This prevents uncontrolled and unwanted movement of the vehicle door during an opening process.
