[0035] Reference Figures 1 to 3 , which shows a schematic structural diagram of a protection structure described in an embodiment of the present application; reference Figure 4 , which shows a schematic diagram of a tailgate assembly of an existing vehicle; reference Figures 5 to 7 , which shows a schematic diagram of a protection structure described in an embodiment of the present application applied to a tailgate assembly of a vehicle. The protection structure is disposed on the tailgate assembly, and the tailgate assembly has a sharp corner portion 61. The protection structure may specifically include: a driving member 10, a transmission member 20, and a protection member 30; the transmission member 20 is connected to the driving member 10, and the protection member 30 is connected to an end of the transmission member 20 away from the driving member 10. The driving member 10 drives the transmission member 20 to rotate, and the transmission member 20 drives the protection member 30 to switch between a first position and a second position; in the first position, the protection member 30 covers the sharp corner portion 61 of the tailgate assembly, and in the second position, the protection member 30 releases the covering of the sharp corner portion 61.

[0036] In the embodiment of the present application, the tailgate of the vehicle is also the trunk door. As Figure 4 shown, the waist position of the tailgate frame usually has a sharp corner portion 61. As Figure 5 and Figure 7 shown, when the tailgate of the vehicle is opened and the sharp corner portion 61 of the door frame edge is exposed, the driving member 10 can drive the transmission member 20 to drive the protection member 30 to switch to the first position, so that the protection member 30 covers the sharp corner portion 61 of the door frame edge to form protection, avoiding the sharp corner portion 61 from easily hitting the human body when the user opens the tailgate to pick up and place items, avoiding harm to the user, and reducing potential safety hazards. As Figure 6 shown, when there is no need to open the tailgate to pick up and place items, that is, when the tailgate of the vehicle is closed, the driving member 10 can drive the transmission member 20 to drive the protection member 30 to switch to the second position, so that the protection member 30 releases the covering of the sharp corner portion 61, avoiding affecting the normal closing of the tailgate. And the structure is simple and the operation is convenient, making the vehicle have better safety and convenience.

[0037] Specifically, in the embodiment of the present application, the driving member 10 is used to provide a relatively stable and reliable power source. The driving member 10 can be electrically connected to the main control system of the vehicle or the vehicle ECU (Electronic Control Unit). For example, when the tailgate is opened, the main control system can send a first driving signal to the driving member 10. The driving member 10 receives the first driving signal and drives the transmission member 20 to drive the protection member 30 to switch to the first position to cover the sharp corner portion 61. When it is necessary to close the tailgate, the main control system can send a second driving signal to the driving member 10. The driving member 10 receives the second driving signal and drives the transmission member 20 to rotate in the reverse direction to drive the protection member 30 to switch to the second position, so that the protection member 30 is away from the sharp corner portion 61. For example, the driving member 10 can be a motor or a motor, etc. The specific type of the driving member 10 in the embodiment of the present application may not be limited.

[0038] Optionally, in the embodiment of the present application, the protection member 30 is a flexible sleeve. The flexible sleeve can be sleeved on the sharp corner portion 61 of the tailgate, has good wrapping property for the sharp corner portion 61, and can achieve a good protection effect. Moreover, the flexible sleeve has good flexibility and wear resistance, which can extend the service life of the protection member 30. For example, the material of the protection member 30 can be rubber or silica gel, or other soft rubber structures, etc. The specific material of the protection member 30 in the embodiment of the present application may not be limited.

[0039] In the embodiment of the present application, optionally, the transmission member 20 includes a rotating rod 21 and a transmission rod 22. The rotating rod 21 is connected to the output end of the driving member 10, the transmission rod 22 is connected to the end of the rotating rod 21 away from the driving member 10, and the protection member 30 is connected to the end of the transmission rod 22 away from the rotating rod 21. The driving member 10 drives the rotating rod 21 to rotate, the rotating rod 21 drives the transmission rod 22 to move, and the transmission rod 22 drives the protection member 30 to switch between the first position and the second position. In this way, the output end of the driving member 10 outputs a rotational torque to the rotating rod 21, so that the rotating rod 21 can rotate around its axis. Further, the rotating rod 21 drives the transmission rod 22 to rotate around the rotating rod 21 as the center, so that the transmission rod 22 drives the protection member 30 to move. The rotational torque of the driving member 10 is transmitted through the rotating rod 21, and it is simple and convenient to adjust the position of the protection member 30 according to the actual spatial layout structure through the transmission rod 22.

[0040] For example, in the embodiment of the present application, when the transmission rod 22 drives the protection member 30 to switch between the first position and the second position, the rotation angle of the rotating rod 21 driving the transmission rod 22 to rotate can be 180°, or 150°, or 120°, etc., which can be set according to actual needs. The rotation angle of the rotating rod 21 driving the transmission rod 22 in the embodiment of the present application may not be limited.

[0041] Optionally, in the embodiment of the present application, the rotating rod 21 extends in the vertical direction, and the transmission rod 22 extends in the horizontal direction. In this way, the axial direction of the rotating rod 21 is arranged in the vertical direction, which can better transmit the rotational torque output by the driving member 10. And the axial direction of the transmission rod 22 is arranged in the horizontal direction, so that the rotating rod 21 drives the transmission rod 22 to rotate in the horizontal direction to adjust the position of the protection member 30.

[0042] In the embodiment of the present application, optionally, the protection structure further includes a housing 40. The housing 40 is connected to the tailgate assembly, the driving member 10 is connected inside the housing 40, and the transmission member 20 is connected to the driving member 10 and extends out of the housing 40. In this way, the driving member 10 is protected by the housing 40, avoiding that the driving member 10 is easily abraded by contacting other structures during movement, affecting the performance of the driving member 10, or damaging other structures. And, connecting the transmission member 20 to the driving member 10 and extending it out of the housing 40 enables the transmission member 20 to have better freedom of movement and avoids the housing 40 from hindering the movement of the transmission member 20.

[0043] Optionally, in the embodiment of the present application, the housing 40 includes a bottom plate 41 and a cover 42. The driving member 10 is connected to the bottom plate 41, and the cover 42 covers the driving member 10 and is connected to the bottom plate 41. In this way, during the assembly process, the bottom plate 41 can be installed first, then the driving member 10 is connected to the bottom plate 41, and then the cover 42 is covered on the driving member 10 and connected to the bottom plate 41, forming a good protective effect on the driving member 10 and making the assembly operation relatively simple and convenient. For example, a circuit can be arranged on the bottom plate 41 to electrically connect the driving member 10 to the vehicle's main control system or the on-board computer.

[0044] In the embodiment of the present application, the housing 40 can be provided with an opening, and the transmission member 20 passes through the opening to extend out of the housing 40. Specifically, the opening can be provided on the cover. The shape and size of the opening can be set according to the shape and size of the transmission member 20 as required. The embodiment of the present application does not limit the specific shape and size of the opening.

[0045] In summary, the protection structure described in the embodiment of the present application has at least the following advantages:

[0046] In the embodiment of the present application, the protection structure is disposed on the tailgate assembly, and the tailgate assembly has a sharp corner portion.

The driving member drives the transmission member to rotate, and the transmission member drives the protection member to switch between a first position and a second position; in the first position, the protection member covers the sharp corner portion of the tailgate assembly, and in the second position, the protection member releases the covering of the sharp corner portion. In this way, when the vehicle tailgate is opened and the sharp corner portion of the door frame edge is exposed, the driving member can drive the transmission member to drive the protection member to switch to the first position, so that the protection member covers the sharp corner portion of the door frame edge to form protection, avoiding the sharp corner portion from easily hitting the human body when the user opens the tailgate to pick up or place items, avoiding harm to the user, and reducing potential safety hazards. When there is no need to open the tailgate to pick up or place items, that is, when the vehicle tailgate is closed, the driving member can drive the transmission member to drive the protection member to switch to the second position, so that the protection member releases the covering of the sharp corner portion, avoiding affecting the normal closing of the tailgate. Moreover, the structure is simple and the operation is convenient, making the vehicle have better safety and convenience.
