[0024] Next, specific embodiments of the present utility model will be described in detail with reference to the drawings, but it is not a limitation of the present utility model.
[0025] It should be noted that the terms "first", "second", etc. in the description and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present utility model described here can be implemented in an order different from those illustrated or described here. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.
[0026] This specification may use the phrase "in one embodiment", "in another embodiment", "in yet another embodiment" or "in other embodiments", which can all refer to one or more of the same or different embodiments according to the present utility model.
[0027] The present utility model provides a sealing structure for a rear door lock body, including a first limiting member 1 and a seal 2 connected to the first limiting member 1. The seal 2 is disposed around the exposed opening 101 of the lock body on the inner panel 100 of the rear door. The first limiting member 1 is installed on the inner panel 100 of the rear door, and the first limiting member 1 is used for mating connection with a second limiting member provided on the vehicle body.
[0028] Combined with Figure 1 and Figure 2 As shown, the inner panel 100 of the rear door and the outer panel 200 of the rear door are connected to each other to form an inner cavity, and the lock body 300 is installed in this inner cavity. A lock body exposure port 101 is provided on the inner panel 100 of the rear door, so that the lock body 300 is exposed, facilitating the locking connection between the lock hook on the vehicle body and the lock body 300 when the rear door is closed. The first limiting member 1 can be installed on the inner panel 100 of the rear door through fasteners or other connection methods. A second limiting member (the relevant parts of the vehicle body are not shown in the figure) is provided on the vehicle body corresponding to the position of the first limiting member 1. The specific cooperation structure between the first limiting member 1 and the second limiting member can be designed as needed. For example, one of the first limiting member 1 and the second limiting member is a plug pin, and the other is a slot, and the limiting effect of the rear door relative to the vehicle body is achieved through the plug-in cooperation; or, a second protrusion is provided on one of the first limiting member 1 and the second limiting member, and a second groove 11 is provided on the other, and the second protrusion is connected with the second groove 11 to achieve the limiting effect of the rear door relative to the vehicle body. The sealing member 2 can be made of corresponding materials as needed, which is not limited here. The sealing member 2 is arranged around the lock body exposure port 101. When the rear door is closed, at least part of the sealing member 2 will be squeezed by the vehicle body (in this specification, it is described by taking the sealing member 2 being squeezed by the vehicle body sheet metal as an example. It should be understood that the sealing member 2 can also be squeezed by other structures on the vehicle body to achieve the same or similar sealing effect), thereby forming a certain sealed space.
[0029] It should be noted that the connection method between the first limiting member 1 and the sealing member 2 can be designed as needed. For example, the first limiting member 1 and the sealing member 2 can be connected together through connection methods such as bonding and fastener connection, which is not limited here.
[0030] The rear door lock body sealing structure of the present utility model, through the cooperation connection between the first limiting member 1 and the second limiting member on the vehicle body, plays a limiting role for the rear door, can reduce the abnormal noise caused by the collision between the lock body 300 and the lock hook during driving, and because the first limiting member 1 is connected to the sealing member 2, the first limiting member 1 is closer to the position of the lock body 300 (i.e., the position of the lock body exposure port 101), that is, the limiting position is closer to the vibration source, further suppressing the jitter of the rear door, thereby achieving a better effect of reducing abnormal noise; by arranging the sealing member 2 around the lock body exposure port 101, when the rear door is closed, the lock hook on the vehicle body can be smoothly locked with the lock body 300, and at the same time, the sealing member 2 is in sealing contact with the vehicle body, forming a sealing protection effect on the lock body 300, which can prevent impurities such as dust and rainwater from entering the lock body 300, reduce the failure rate of the lock body 300, and improve the service life of the lock body 300.
[0031] Furthermore, the sealing member 2 includes a sealing portion 21 and a clamping portion 22 which are connected to each other, the sealing portion 21 is used for sealingly contacting the vehicle body, the clamping portion 22 and the sealing portion 21 form a first groove 23, and the tailgate inner panel 100 around the lock body exposure opening 101 is clamped in the first groove 23.
[0032] Combination Figure 2 and Figure 3 As shown, the sealing part 21 is connected to the clamping part 22, and the sealing part 21 and the clamping part 22 form a U-shaped groove, namely, a first groove 23, and the back door inner plate 100 around the lock body exposure opening 101 (namely, the edge of the lock body exposure opening 101) is clamped in the first groove 23, so that the sealing member 2 is clamped and fixed around the lock body exposure opening 101. The end of the sealing part 21 away from the back door inner plate 100 can withstand the extrusion of the body sheet metal, so as to play a sealing and protective effect on the lock body 300.
[0033] In this way, the sealing protection function of the lock body 300 is achieved through the sealing portion 21. At the same time, the first groove 23 formed by the clamping portion 22 and the sealing portion 21 is clamped with the tailgate inner panel 100 around the lock body exposure opening 101, ensuring that the seal 2 is firmly installed around the lock body exposure opening 101, thereby ensuring that it has sufficient sealing performance.
[0034] Furthermore, the tailgate inner panel 100 includes a front inner panel 110 and a side inner panel 120, the front inner panel 110 is connected to the edge of the tailgate outer panel 200 through the side inner panel 120, and a first protrusion 221 is provided on the side of the clamping portion 22 close to the side inner panel 120, and the first protrusion 221 is clamped at the connection between the front inner panel 110 and the side inner panel 120.
[0035] Combination Figure 1 As shown, the front inner panel 110 and the side inner panel 120 are integrated, and the side inner panel 120 is arranged at the edge of the front inner panel 110, so as to connect the side inner panel 120 with the edge of the back door outer panel 200, and form the above-mentioned inner cavity between the back door inner panel 100 and the back door outer panel 200. Figure 2 , Figure 3 and Figure 4As shown, a first protrusion 221 is provided on the clamping portion 22. The design of the first protrusion 221 makes the width of the seal 2 greater than the width of the corresponding position of the exposed opening 101 of the lock body, so that the first protrusion 221 extends into the inner cavity from the exposed opening 101 of the lock body (i.e., the inner cavity between the inner panel 100 and the outer panel 200 of the rear door), realizing the function of clamping and fixing. At the same time, the first protrusion 221 can also play the same role as the clamping portion 22, that is, the first protrusion 221 and the sealing portion 21 enclose an extended groove 24 connected to the first groove 23, making the installation of the sealing portion 21 more stable and ensuring that the sealing performance meets the requirements.
[0036] Preferably, a bottle opener 12 is provided on the first limiting member 1.
[0037] Combined Figure 1 and Figure 2 As shown, the rear door in this embodiment is a side-opening rear door.
