    The present invention discloses a linkage mechanism for a vehicle control system, including a base. The upper end of the base is provided with a first connection block. A second connection block is arranged above the first connection block. A second connection rod is arranged in the middle of the second connection block. A linkage component is arranged between the first connection block and the second connection block. The linkage component includes two linkage sleeves in mirror image arrangement. A gap is formed in one end portion of each linkage sleeve. A connection hole is formed in a side end of the gap. The present invention has the linkage component. In a rotating process of an engine hood, a first spring and a second spring play a buffer role to protect the entire linkage mechanism. When the second spring is compressed to a maximum compression amount, linkage sleeves cannot collide with each other, so that the service life is prolonged. Meanwhile, the base is slidably arranged at an upper end of the first connection block. When the engine hood needs to be opened to a relatively large opening angle, the first connection block slides on the base to fit the larger opening angle, and therefore, the application range is increased.

    LINKAGE MECHANISM FOR VEHICLE CONTROL SYSTEM
    BACKGROUND Technical Field The present invention relates to the field of control of vehicles, and more particularly relates to a linkage mechanism for a vehicle control system. Related Art Vehicle control 1s actually to apply some automatic control technologies to a transportation system, such that the conventional improvement of the mechanical performance 1s developed for assistance in or partial or complete replacement of manual manipulation, so as to reduce accidents caused by human limitations, reduce the driving intensity and improve the transportation efficiency. The vehicle control is divided into a sensor, an electronic control unit and an actuation mechanism. For example, opening and closing processes of an engine hood can be automatically controlled.
    The existing engine hood is driven to rotate by a driving member in the opening process.
    When rotated to a certain angle, the engine hood cannot continue to rotate, and cannot be opened to a larger opening angle, which causes extremely high limitation. Meanwhile, after long-time opening and closing, a linkage mechanism between the engine hood and a vehicle body 1s prone to wear, which causes damage to the linkage mechanism. It is likely to cause safety accidents if the damaged linkage mechanism is not repaired timely.
    SUMMARY In order to overcome the deficiencies mentioned in the background, the present invention is directed to provide a linkage mechanism for a vehicle control system. The present invention has a linkage component. In a rotating process of an engine hood, a first spring and a second spring play a buffer role to protect the entire linkage mechanism. When the second spring is compressed to a maximum compression amount, linkage sleeves cannot collide with each other, so that the service life is prolonged.
    Moreover, a base is slidably arranged at an upper end of a first connection block. When the engine hood needs to be opened to a relatively large opening angle, the first connection block slides on the base to fit the larger opening and closing angle, and therefore, the application range 1s increased.
    The objective of the present invention is achieved through the following technical solutions: A linkage mechanism for a vehicle control system includes a base. A sliding slot is formed in the base. An upper end of the base is provided with a first connection block. A first connection rod is arranged in the middle of the first connection block. A bottom end of the first connection block is provided with a sliding block.
    A second connection block is arranged above the first connection block. A second connection rod 1s arranged in the middle of the second connection block. A linkage component is arranged between the first connection block and the second connection block.
    The linkage component includes two linkage sleeves in mirror image arrangement. A gap 1s formed in one end portion of each linkage sleeve. A connection hole is formed in a side end of the gap.
    A cavity is formed in the other end portion of the linkage sleeve. An annular ring is arranged at an outer side end of the cavity. A linkage loop bar is arranged between the linkage sleeves, and limiting plates are arranged at two end portions of the linkage loop bar.
    A first spring is arranged inside each of the cavities. Two ends of the first spring are respectively fixed to inner bottom walls of the limiting plate and the cavity. A second spring penetrates through a side end of the linkage loop bar. Two ends of the second spring are respectively fixed to the annular rings.
    Further, the sliding slot 1s in a T shape, and two ends of the sliding slot do not penetrate through two end portions of the base.
    Further, the sliding block and the sliding slot are in slidable arrangement.
    Further, the connection holes are rotatably connected to the first connection rod and the second connection rod, respectively.
    Further, the linkage loop bar 1s in sliding fit with the annular ring, the limiting plate and the cavity, so that the linkage loop bar may not be separated from the linkage sleeves.

    1. The present invention has the linkage component including the two linkage sleeves in mirror image arrangement; the linkage loop bar is arranged between the linkage sleeves; the first spring 1s arranged in each of the cavities of the linkage sleeves; the second spring penetrates through the side end of the linkage loop bar; in the rotating process of the engine hood, the first spring and the second spring play a buffer role to protect the entire linkage mechanism; and when the second spring is compressed to a maximum compression amount, the linkage sleeves cannot collide with each other, so that the service life is prolonged.
    2. The present invention has the first connection block and the base; the base is slidably arranged at the upper end of the first connection block; and when the engine hood needs to be opened to a relatively large opening angle, the first connection block slides on the base to fit the larger opening angle, and therefore, the application range is increased.

    DETAILED DESCRIPTION The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. A linkage mechanism for a vehicle control system, as shown in FIG. 1 and FIG. 2, includes a base 1. A T-shaped sliding slot 11 is formed in the base 1. Two ends of the sliding slot 11 do not penetrate through two end portions of the base 1. An upper end of the base 1 is provided with a first connection block 2. A first connection rod 21 1s arranged in the middle of the first connection block 2. A bottom end of the first connection block 2 is provided with a sliding block 22. The sliding block 22 and the sliding slot 11 are in sliding arrangement.
    As shown in FIG. 1 and FIG. 3, a second connection block 3 is arranged above the first connection block 2. A second connection rod 31 is arranged in the middle of the second connection block 3. A linkage component 4 is arranged between the first connection block 2 and the second connection block 3. As shown in FIG. 4, FIG. 5 and FIG. 6, the linkage component 4 includes two linkage sleeves 41 in mirror image arrangement.
    A gap 4101 is formed in one end portion of each linkage sleeve 41. A connection hole 4102 is formed in a side end of the gap 4101. The connection holes 4102 are rotatably connected to the first connection rod 21 and the second connection rod 31, respectively.
    A cavity 4103 is formed in the other end portion of the linkage sleeve 41. An annular ring 4104 is arranged at an outer side end of the cavity 4103. A linkage loop bar 42 1s arranged between the linkage sleeves 41, and limiting plates 4201 are arranged at two end portions of the linkage loop bar 42. The linkage loop bar 42 1s in sliding fit with the annular ring 4104, the limiting plate 4201 and the cavity 4103, so that the linkage loop bar 42 may not be separated from the linkage sleeves 41. A first spring 43 1s arranged inside each of the cavities 4103. Two ends of the first spring 43 are respectively fixed to inner bottom walls of the limiting plate 4201 and the cavity 4103. A second spring 44 penetrates through a side end of the linkage loop bar 42. Two ends of the second spring 44 are respectively fixed to the annular rings 4104. During use, the base 1 is fixed to a vehicle body.
    The second connection block 3 is fixed to an inner wall of an automobile engine hood, and the engine hood is controlled to be opened through a cylinder or other existing driving members.
    A motion track of the device changes as shown in FIG. 1 to FIG. 7. When the linkage mechanism of the device is as shown in FIG. 1, the engine hood is closed at this time.
    When the linkage mechanism of the device is as shown in FIG. 7, the engine hood is opened at this time.
    In a process of opening the engine hood or closing the engine hood, the linkage component 4 rotates.
    In the rotating process, the first springs 43 and the second spring 44 play a buffer role to protect the entire linkage mechanism and prolong the service life.
    Due to the arrangement of the second spring 44, when the second spring 44 is compressed to a maximum compression amount, the linkage sleeves 41 do not collide with each other.
    Meanwhile, when the engine hood needs to be opened to a relatively large opening angle, the 5 first connection block 2 slides on the base 1 to fit the larger opening angle.
