DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0034] The embodiment of the present application provides a hidden tailgate micro switch installation structure, which can solve the problem in the related art that the micro switch has low adaptability to vehicles of different shapes and requires adaptive adjustment to the rear shape of different models, which greatly increases the cost.

[0035] See also Figure 2 , Figure 3 and Figure 4As shown, the present hidden back door micro switch installation structure mainly includes a back door reinforcement plate 1 and a back door outer plate 2, a micro switch 3 and a driving structure 4 arranged from the inside to the outside, wherein the micro switch 3 is arranged on the back door reinforcement plate 1 and at least partially extends out of the license plate installation area 20 of the back door outer plate 2, and the driving structure 4 includes a first driving rod 40 and a second driving rod 41, wherein the first driving rod 40 is arranged to be tilted upward, and one end is rotatably connected to the side of the micro switch 3 extending out of the back door outer plate 2, and the other end is rotatably connected to the second driving rod 41, and the end of the second driving rod 41 away from the first driving rod 40 is used to extend out of the top of the license plate 21 installed in the license plate installation area 20. The second driving rod 41 is used to drive the connection point between it and the first driving rod 40 to slide downward along the inner wall of the license plate 21 under the action of external force, so as to drive the first driving rod 40 to gradually restore from the tilted state to the horizontal state, and is used to press the micro switch 3 during the restoration process.

[0036] Specifically, after the micro switch 3 is installed, the license plate 21 is installed last. When the license plate 21 is successfully installed, the side of the license plate 21 close to the micro switch 3 is in contact with the connection point between the second driving rod 41 and the first driving rod 40. Since the second driving rod 41 is vertically arranged, the second driving rod 41 is almost in contact with the inner wall of the license plate 21. Therefore, when the micro switch 3 needs to be pressed and an external force is applied to the end of the second driving rod 41 extending out of the top of the license plate 21, since the license plate 21 is fixed to the back The door outer panel 2 cannot move, while the micro switch 3 itself is retractable. Therefore, at this time, the connection point between the second drive rod 41 and the first drive rod 40 will move downward along the inner wall of the license plate 21 under the drive of external force. Since the license plate 21 cannot move, it will exert a reverse force, so that the micro switch 3 is compressed toward the direction of the tailgate reinforcement plate 1 under the drive of the first drive rod 40, and the first drive rod 40 also gradually recovers from the inclined state to the horizontal state in this process. When it is almost reaching the horizontal state, the micro switch 3 is pressed into place to achieve opening.

[0037] Specifically, in order to prevent the connection point between the second drive rod 41 and the first drive rod 40 from sliding and becoming stuck during the sliding process, especially when being driven at the beginning, the inclination of the first drive rod 40 cannot be too large. The determination of the inclination mainly depends on whether the sliding can be achieved smoothly and whether the micro switch 3 can be pressed into place when the first drive rod 40 is restored to a horizontal state. Therefore, the determination of the inclination is determined through multiple tests in actual tests. The inclination value of different vehicle models may vary depending on the space size and other influencing factors.

[0038] The present hidden tailgate microswitch installation structure is different from other vehicle models in which the microswitch 3 is arranged on the tailgate decorative strip or the tailgate outer handle. The present application arranges the microswitch 3 on the tailgate reinforcement plate 1, and makes the microswitch 3 at least partially extend out of the license plate installation area 20 of the tailgate outer panel 2. When it needs to be opened, it can be achieved by directly pressing the second drive rod 41 to extend the end of the license plate 21. Therefore, since the position of the microswitch 3 is located in the license plate installation area 20, when the license plate 21 is installed and fixed, it can completely cover the microswitch 3. When it is necessary to press the microswitch 3 to open it, it is only necessary to press the second drive rod 41 extending from the top of the license plate 21 to press the microswitch 3. This makes the present hidden tailgate microswitch installation structure basically have no requirements on the vehicle shape, can be adapted to vehicles of all shapes, has a high degree of versatility, and does not need to adjust the rear shape of the vehicle during the installation process, has almost no effect on the appearance and the original shape, and reduces the manufacturing cost to a certain extent.

[0039] For further information, see Figure 1 As shown, the hidden tailgate microswitch installation structure also includes an auxiliary structure 5, which specifically includes a connecting portion 50 and an auxiliary plate 51, wherein the connecting portion 50 is sleeved on the microswitch 3 and one end is connected to the tailgate reinforcement plate 1, and the auxiliary plate 51 is arranged at one end of the connecting portion 50 away from the tailgate reinforcement plate 1, and forms a driving gap 52 between the connecting portion 50 and the side of the microswitch 3 away from the tailgate reinforcement plate 1, and the driving gap 52 is used to accommodate the driving structure 4, and the inner wall of the auxiliary plate 51 is in contact with the connection point between the second driving rod 41 and the first driving rod 40.

[0040] Specifically, since the license plate 21 is required to provide a reverse force during the process of pressing the micro switch 3, and the license plate 21 is not manufactured by the automobile manufacturer but is issued by the traffic control department, it cannot affect the structure of the license plate 21. The surface of a general license plate is not absolutely flat and smooth, and generally there will be structures such as convex ribs. The existence of structures such as convex ribs often hinders and has other influences on the sliding of the connection point between the second drive rod 41 and the first drive rod 40, making the pressing process not smooth. In order to avoid the above situation, the auxiliary structure 5 is provided, and the auxiliary plate 51 replaces the function of the previous license plate 21. The connecting part 50 is mainly used to fix the auxiliary plate 51. The inner wall of the auxiliary plate 51 contacts the connection point between the second drive rod 41 and the first drive rod 40 to provide a reverse force and eliminate the influence of the license plate 21 on the sliding of the connection point.

[0041] Furthermore, the present hidden back door micro switch installation structure further comprises an auxiliary structure 5, wherein the auxiliary structure 5 specifically comprises a connecting portion 50 and an auxiliary plate 51, wherein one end of the connecting portion 50 is connected to the back door outer plate 2, and the auxiliary plate 51 is arranged at one end of the connecting portion 50 away from the back door outer plate 2, and forms a driving gap 52 with the side of the micro switch 3 away from the back door reinforcement plate 1, wherein the driving gap 52 is used to accommodate the driving structure 4, and the inner wall of the auxiliary plate 51 contacts the connection point between the second driving rod 41 and the first driving rod 40. Specifically, in addition to being fixed to the back door reinforcement plate 1, the connecting portion 50 can also be directly fixed to the back door outer plate 2. When fixed to the back door reinforcement plate 1, since the back door reinforcement plate 1 is located on the inner side of the back door outer plate 2, compared with fixing the connecting portion 50 to the back door reinforcement plate 1, the length of the connecting portion 50 is shorter when fixed to the back door outer plate 2, thereby saving the amount of materials and costs.

[0042] Furthermore, a slide groove 510 is provided along the height direction of the auxiliary plate 51 on one side close to the micro switch 3 , and the slide groove 510 is used to accommodate the connection point between the second driving rod 41 and the first driving rod 40 .

[0043] Specifically, the rotational connection between the second driving rod 41 and the first driving rod 40 is a rotation within a vertical plane. Similarly, the rotational connection between the first driving rod 40 and the micro switch 3 is also a rotation within a vertical plane, and the two vertical planes are located on the same vertical plane. In order to ensure the smooth progress of the pressing process, a slide groove 510 is also provided on the inner side surface of the auxiliary plate 51 along its height direction, which can ensure that the connection point slides along the slide groove 510, thereby ensuring the smooth progress of the pressing process and protecting the second driving rod 41, the first driving rod 40 and the rotating connection member provided therebetween to a certain extent.

[0044] For further information, see Figure 6 As shown, a limit stop block 511 is provided on the slide groove 510, and the limit stop block 511 is configured as follows: when the second drive rod 41 is driven by an external force to slide the connection point between the second drive rod 41 and the first drive rod 40 downward along the slide groove 510, and the first drive rod 40 returns to a horizontal state, the connection point is in contact with the limit stop block 511.

[0045] Specifically, since the first drive rod 40 and the micro switch 3 are rotationally connected, and the first drive rod 40 and the second drive rod 41 are also rotationally connected, it is not easy to judge whether the first drive rod 40 is driven to recover from the inclined state to the horizontal state during the process of pressing the second drive rod 41. There is a possibility that the first drive rod 40 may be converted from the horizontal state to the downward inclined state due to over-pressing. Therefore, in order to avoid the above problem, a limit stop block 511 is added to the slide groove 510. When the second drive rod 41 is driven by an external force to slide the connection point between it and the first drive rod 40 downward along the slide groove 510, and the first drive rod 40 is restored to the horizontal state, the connection point is in contact with the limit stop block 511 at this time, and the limit stop block 511 can prevent the connection point from being pressed too much.

[0046] Furthermore, since there is a rigid contact between the slide groove 510 and the connection point, and since the connection point and the slide groove 510 are always in a state of friction contact, in order to avoid damage to the slide groove 510 and the connection point after long-term use, the inner wall of the slide groove 510 is paved with an elastic wear-resistant layer, which has a certain elasticity and can prevent the connection point from directly contacting the slide groove 510, thereby alleviating the wear between the two to a certain extent. It should also be noted that since the elastic wear-resistant layer is elastic, it has a certain deformation ability, so when the connection point slides, it will undergo a slight deformation to help the first connecting rod recover from an inclined state to a horizontal state.

[0047] Furthermore, the connecting portion 50 is a sleeve structure whose shape matches that of the micro switch 3 .

[0048] Furthermore, the connecting portion 50 includes a plurality of connecting rods disposed at intervals, one end of each of the connecting rods is connected to the tailgate reinforcement plate 1 or the tailgate outer plate 2 , and the other end is connected to the auxiliary plate 51 .

[0049] Specifically, the connecting portion 50 can be a sleeve structure or a connecting rod structure. When it is a sleeve structure, since the connecting portion 50 mainly serves to connect and fix the auxiliary plate 51, the overall structural strength is better when it is a sleeve structure; and when it is a structure of multiple connecting rods arranged at intervals, materials are saved while ensuring that it has sufficient structural strength.

[0050] Furthermore, since the diameter of the second driving rod 41 itself is very small, and the operator needs to manually press the second driving rod 41 each time it is opened, in order to improve the comfort and experience during use, the end of the second driving rod 41 that is used to extend out of the top of the license plate 21 is provided with a cap 410, and the overall cross-sectional area of ​​the cap 410 is larger than the cross-sectional area of ​​the second driving rod 41.

[0051] For further information, see Figure 5 As shown, the back door reinforcement plate 1 specifically includes a first reinforcement portion 10, a second reinforcement portion 11 and a third reinforcement portion 12 arranged from top to bottom, the first reinforcement portion 10 is used to install and fix the rear wiper structure 6, the second reinforcement portion 11 is used to install and fix the micro switch 3, and the third reinforcement portion 12 is used to install and fix the tailgate lock structure 7.

[0052] Specifically, the rear wiper structure 6 is assembled on the first reinforcement part 10 at the top of the back door reinforcement plate 1 by bolts, the micro switch 3 is fastened to the second reinforcement part 11 in the middle of the back door reinforcement plate 1 by bolts, and the micro switch 3 extends out after passing through the flange hole of the sheet metal of the back door reinforcement plate 1, and finally extends out from the back door outer plate 2, and the tailgate lock structure 7 is also fixed on the third reinforcement part 12 at the bottom of the back door reinforcement plate 1 by bolts, wherein the back door reinforcement plate 1 plays the role of simultaneously installing the rear wiper structure 6, the micro switch 3 and the tailgate lock structure 7, taking into account the CAE performance balance. After the micro switch 3 is assembled, since the auxiliary structure 5 has been pre-arranged on the back door reinforcement plate 1 or the back door outer plate 2, when the license plate 21 is later registered, the license plate 21 can cover the micro switch 3, and the micro switch 3 is triggered by pressing the cap 410 on the top of the license plate 21, thereby realizing the opening of the back door.
