Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0032] In the description of the present invention, it should be noted that the term "including" and its variations represent open inclusion, that is, "including but not limited to". The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. In addition, in the description of the present invention, the meaning of "several" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0033] The present invention provides a contactless vehicle trunk opening system. Figure 1 As shown, it includes a kick sensor 1 and a protective device 3, wherein the protective device 3 includes a protective shell 31 and a connecting assembly. The kick sensor 1 is arranged in the protective shell 31 through a number of connecting assemblies, which can prevent the kick sensor 1 from being easily hit by flying stones during use, thereby protecting the kick sensor 1. The protective shell 31 includes a box body with an opening at the bottom; the connecting assembly includes a support tube 32 and a connecting seat 34, wherein the bottom wall of the support tube 32 is detachably connected to the inner wall of the protective shell 31; the first end of the connecting seat 34 is connected to the kick sensor 1, and the second end of the connecting seat 34 extends into the support tube 32, and an elastic component is arranged between the second end surface of the connecting seat 34 and the bottom wall of the support tube 32. Preferably, the elastic component is arranged as a compression spring 33 or a rubber block.

[0034] The first end of the connecting seat 34 can be connected to the kick sensor 1 by a second screw 344 to support the kick sensor 1, and then the connecting seat 34 is supported by the supporting tube 32. An elastic component is arranged between the second end surface of the connecting seat 34 and the bottom wall of the supporting tube 32, so that the kick sensor 1 is flexibly connected to the protective shell 31, and the vibration transmitted from the protective shell 31 to the supporting tube 32 can be buffered and absorbed, thereby preventing the kick sensor 1 from being subjected to large vibrations during use and strengthening the protection of the kick sensor 1.

[0035] According to the size of the space in the box body, at least two connecting components are arranged opposite to each other to keep the kick sensor 1 stably installed. When there are two connecting components, the two connecting components are arranged on two opposite inner side walls far from the kick sensor 1. When the space in the box body is larger, the connecting components can also be arranged on four opposite inner side walls of the box body. The two connecting components arranged opposite to each other have the same specifications, which is convenient for assembly.

[0036] Preferably, the connecting seat 34 can be guided to move in the support tube 32, and the diameter of the compression spring 33 is slightly smaller than the inner diameter of the support tube 32, and there is a small gap between the compression spring 33 and the inner wall of the support tube 32, so as to keep the compression and extension directions of the compression spring 33 stable.

[0037] In one embodiment, Figure 2 As shown, the inner wall of the opening end of the support tube 32 is provided with a limiting groove 321, and the outer wall of the connecting seat 34 is provided with a limiting slider 341 adapted to the limiting groove 321, and the limiting slider 341 is accommodated in the limiting groove 321. When the connecting seat 34 moves in the support tube 32, the limiting groove 321 facilitates the limiting guide of the limiting slider 341, and can also limit the left and right displacement range of the connecting seat 34. Preferably, the limiting groove 321 and the limiting slider 341 are both symmetrically arranged, and the limiting slider 341 can be fixedly connected to the connecting seat 34 by means of clamping or welding. Alternatively, the limiting groove 321 can also be circumferentially arranged on the inner wall of the opening end of the support tube 32, and the limiting slider 341 is circumferentially arranged on the outer wall of the connecting seat 34. At this time, the limiting slider 341 and the connecting seat 34 can be fixedly connected by means of threaded matching connection or welding.

[0038] In one embodiment, Figure 3As shown, the second end of the connecting seat 34 is set to be T-shaped, including a moving part 342 and an extruding part 343, and the extruding part 343 is threadedly connected to the end of the free end of the moving part 342; the extruding part 343 is arranged in the support tube 32 with clearance. The diameter of the extruding part 343 is slightly smaller than the inner wall of the support tube 32, and larger than the diameter of the compression spring 33, and the movement of the connecting seat 34 in the support tube 32 can be guided by the size matching of the connecting seat 34 and the support tube 32. Specifically, the free end of the moving part 342 can be set as a threaded rod, a blind threaded hole is set in the middle of the extruding part 343, and the threaded rod is threadedly connected to the extruding part 343. It is also possible to set a threaded hole in the moving part 342, set the extruding part 343 to be T-shaped, the extruding part 343 includes a connecting rod and an extruding head arranged at the end of the connecting rod, and the connecting rod is set as a threaded rod, and the connecting rod is threadedly connected to the moving part 342. The moving part 342 and the extruding part 343 are connected by threaded fit, which is convenient for connection. The length of the connecting seat 34 can also be adjusted, thereby adjusting the compression state of the elastic component to adapt to protective shells 31 of different sizes.

[0039] In order to ensure the connection between the connection seat 34 and the support tube 32 is stable and prevented from being loosened, a movable blocking cover 323 is sleeved on the second end of the connection seat 34, and the blocking cover 323 is detachably connected to the end wall of the open end of the support tube 32. When the connection seat 34 moves in the support tube 32, the blocking cover 323 is still fixed to the open end of the support tube 32, and the connection seat 34 can move through the blocking cover 323. When the connection seat 34 moves away from the bottom wall of the support tube 32, the blocking cover 323 can block and limit the limiting slider 341 or the extrusion part 343 to prevent the connection seat 34 from sliding out of the support tube 32, thereby avoiding the risk of the kick sensor 1 falling due to the connection component losing its connection support function.

[0040] The blocking cover 323 can be connected to the end wall of the open end of the support tube 32 by means of a third screw 324, so as to facilitate the assembly of the connection seat 34 into the support tube 32. When the connection seat 34 is provided with an extrusion portion 343, the blocking cover 323 can be inserted from the moving portion 342 of the connection seat 34 first, and then the extrusion portion 343 can be screwed on; when the outer wall of the connection seat 34 is provided with a limiting slider 341, the blocking cover 323 can be inserted from the second end of the connection seat 34, and then the limiting slider 341 can be fixed to the outer wall of the connection seat 34.

[0041] In order to facilitate the disassembly and assembly of the kick sensor 1, the bottom wall of the support tube 32 is attached to the inner wall of the box body, and the support tube 32 is connected to the protective shell 31 by the first screw 322, which can firmly connect the kick sensor 1 to the protective shell 31 and improve the stability of the connection of the first screw 322. According to the size of the support tube 32, one or more first screws 322 can be provided. In the later use process, the maintenance personnel only need to loosen and disassemble each first screw 322 respectively with the help of an external wrench, and then the kick sensor 1 and the connecting assembly can be taken out of the protective shell 31 as a whole, which is convenient and quick to disassemble and assemble.

[0042] In one embodiment, a first shock absorbing sheet 36 is disposed on the outer side of the top plate 35 of the box body, and a second shock absorbing sheet is disposed on the inner side wall of the box body. The first shock absorbing sheet 36 and the second shock absorbing sheet can be glued and fixed to the box body.

[0043] The top plate 35 of the box body is set as a flange structure, and a connecting hole 351 is set on the flange of the top plate 35, so that the top plate 35 can be installed and fixed on the lower end surface of the rear of the vehicle by connecting bolts, so as to fix the protective device 3 and the kick sensor 1 to the vehicle. The first shock-absorbing sheet 36 can cover the entire outer side of the top plate 35, and a avoidance hole 361 is set at the position corresponding to the connecting hole 351 for the connecting bolt to pass through. The first shock-absorbing sheet 36 is made of EVA foam, which has a good buffering and shock-absorbing effect, and can prevent the vibration generated by the vehicle from being directly transmitted to the top plate 35.

[0044] When two connecting components are arranged opposite to each other, the second shock-absorbing sheet is preferably arranged on the inner wall of the box body where no connecting component is arranged, or the second shock-absorbing sheet can be arranged on all four inner walls of the box body. The second shock-absorbing sheet is made of closed-cell sponge rubber, which can prevent the end face of the kick sensor 1 from directly making hard contact with the protective shell 31 when the protective shell 31 is deformed.

[0045] In one embodiment, the system further includes a vehicle key detection module 2, which is disposed on the kick sensor 1 and located between the kick sensor 1 and the top plate 35 of the protective shell 31. The vehicle key detection module 2 can be installed in the middle position of the upper end surface of the kick sensor 1, and the protective shell 31 can protect the vehicle key detection module 2 at the same time.

[0046] The kick sensor 1 and the vehicle key detection module 2 can be connected to the external vehicle body controller signal through a signal line, and the external vehicle body controller is connected to the external vehicle electric trunk signal through a signal line. The kick sensor 1 is convenient for detecting whether there is an object sweeping below. When an object sweeps below the kick sensor 1, the kick sensor 1 will send an electrical signal to the external vehicle body controller, and the vehicle key detection module 2 will detect the external vehicle key signal at the same time. When the vehicle key detection module 2 detects the external vehicle key signal, it will also send an electrical signal to the external vehicle body controller. At this time, the external vehicle body controller sends an electrical signal to control the external vehicle electric trunk to open, thereby opening the trunk without contact. When the vehicle key detection module 2 does not detect the external vehicle key signal, the external vehicle body controller will not control the external vehicle electric trunk to open.

[0047] In one embodiment, a protective mesh cover 4 is provided between the top plate 35 of the box body and the vehicle key detection module 2, and a moisture-absorbing ball 5 is provided inside the protective mesh cover 4. The moisture-absorbing ball 5 is made of moisture-proof silica gel, and the protective mesh cover 4 blocks and stores the moisture-absorbing ball 5. The moisture-absorbing ball 5 can absorb moisture around the vehicle key detection module 2 through the protective mesh cover 4, so as to prevent a large amount of moisture from accumulating around the vehicle key detection module 2 and affecting its service life.

[0048] Specifically, the protective mesh cover 4 can be set as an isolation mesh structure, the moisture-absorbing ball 5 is installed in the box body, and then the protective mesh cover 4 is assembled, and the moisture-absorbing ball 5 is accommodated in the space between the protective mesh cover 4 and the top plate 35 of the box body. The protective mesh cover 4 can also be set as a mesh box, the moisture-absorbing ball 5 is installed in the mesh box, and then the mesh box is installed on the protective shell 31. The protective mesh cover 4 can be detachably connected to the top plate 35 of the box body by the fourth screw 41, and can also be connected to the inner wall of the box body. For example, a cross-slot fixing screw can be installed on the lower end surface of the top plate 35, and the protective mesh cover 4 is installed and fixed in the middle position of the lower end surface of the top plate 35 by the cross-slot fixing screw. The cross-slot fixing screw facilitates the installation and fixation of the protective mesh cover 4.

[0049] The present invention also provides a method for assembling a contactless vehicle trunk opening system, which is used to assemble the above-mentioned opening system, and the method comprises the following steps:

[0050] Step 1: Place the moisture absorbing ball 5 in the protective mesh 4 and assemble the protective mesh 4 to the protective shell 31;

[0051] Step 2, assemble the connection base 34 with the blocking cover 323 to the kick sensor 1; after the elastic component is installed in the support tube 32, the support tube 32 is sleeved on the second end of the connection base 34;

[0052] Step 3, fixing the blocking cover 323 to the supporting tube 32;

[0053] Step 4, move the support tube 32 toward the kick sensor 1, put the kick sensor 1 into the box body, and then move the support tube 32 away from the kick sensor 1, so that the bottom wall of the support tube 32 fits the inner wall of the box body;

[0054] Step 5: Connect the bottom wall of the support tube 32 to the protective shell 31 by using the first screw 322 .

[0055] The connection assembly is first installed on the kick sensor 1 and then placed in the box body. The distance between the bottom walls of the two support tubes 32 can be flexibly adjusted by the elastic component, so that the kick sensor 1 with the connection assembly installed can be conveniently placed in the box body. By this method, the kick sensor 1 can be conveniently assembled in the protective shell 31, and the installation is convenient and quick.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
