Description

Technical Field

[0001] This utility model relates to the field of automotive door locks, and in particular to a latch. Background Technology

[0002] The tailgate lock latch is a core component fixed to the tailgate frame (usually the frame of the trunk lid or rear hatch) and precisely engages with the latch / lock block in the tailgate lock body to achieve mechanical locking, positioning, and fixation of the tailgate. It is a key mechanical structure that ensures the tailgate can close tightly, does not loosen while driving, and provides anti-theft security.

[0003] Currently, when a car tailgate closes, the lock on the tailgate may collide with the latch on the car body, resulting in a loud impact noise. This negatively impacts the user experience, and long-term impact can also affect the lifespan of the door lock and latch. This issue needs further improvement and refinement. Utility Model Content

[0004] To further reduce the impact noise when the tailgate closes, this application provides a latch.

[0005] This application provides a locking mechanism, which adopts the following technical solution: A latch includes a base plate and a buckle. The base plate has symmetrically arranged columns on both sides. A rubber buffer block is detachably fitted on the column. The side of the rubber buffer block near the buckle is used to abut against the lock body. A pad is provided at the bottom of the base plate for fixing the vehicle body. The base plate is covered with a rubber layer, and there is a rubber layer between the base plate and the pad.

[0006] Optionally, the top of the column has an anti-detachment part, the width of which is greater than the width of the column, and the width of which gradually increases from the top to the bottom.

[0007] Optionally, the bottom of the rubber buffer block has an extended flange.

[0008] Optionally, the base plate is provided with a connecting hole for connection and fixation, the connecting hole penetrating the base plate and the rubber layer.

[0009] Optionally, the base plate has a recessed portion around the corresponding connection hole, and the rubber layer has a protrusion that matches the recessed portion.

[0010] Optionally, the pad is provided with a positioning ring that passes through the connection hole, and the side of the rubber layer facing away from the pad has a bushing that is fastened and fixed to the positioning ring. The bushing and the positioning ring are connected and fastened to the middle rubber layer and the base plate.

[0011] Optionally, one side of the rubber layer is provided with a groove adapted to the pad, and the other side is provided with a positioning groove adapted to the bushing.

[0012] Optionally, the base plate has through positioning holes, which are symmetrically arranged on both sides of the buckle.

[0013] Optionally, the rubber layer has outwardly convex edges on both sides, which are used to abut against the supporting flange.

[0014] Optionally, the two ends of the buckle are riveted to the base plate, and the middle part of the pad is used to avoid the avoidance part at the end of the buckle.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. By installing rubber buffer blocks on both side pillars, the lock body and the buckle cooperate when the tailgate is closed. The two sides of the lock body abut against the side walls of the two rubber buffer blocks, achieving a good buffering and shock absorption effect, thereby reducing the impact noise generated when the tailgate is closed. It also effectively alleviates the impact between the lock body and the buckle, extending the service life of the lock body and the buckle. In addition, the rubber buffer blocks are independently detachable, and can be removed and replaced individually when wear occurs after long-term use. Disassembly and replacement are simple and convenient. 2. The base plate is covered with a rubber layer. After the base plate and the pad are connected, the rubber layer is located between the two. The pad is fixedly connected to the vehicle body. This achieves a soft connection between the base plate and the vehicle body, which can play a buffering and shock-absorbing role during the car's operation. This effectively reduces the sound transmitted from the tailgate lock during the car's operation and achieves a better noise reduction effect. 3. The fastening and fixing of the positioning ring and the bushing on the pad plate can, on the one hand, press the rubber layer and the base plate together, making the connection between the two tighter and less prone to relative movement. On the other hand, the center of the bushing and the positioning ring forms a connecting hole for fasteners to pass through. When fasteners are passed through for fixing, the fasteners abut against the inner wall of the bushing to achieve hard contact, which is not easy to damage the rubber layer and plays a protective role for the rubber layer, realizing the multiple uses of the bushing.

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] A type of latch, such as Figures 1-4 As shown, it includes a base plate 1, a pad plate 2, and a buckle 3. The two ends of the buckle 3 are fixed to the base plate 1 by riveting. A rubber layer 4 is covered on the surface of the base plate 1. The rubber layer 4 is distributed on the top and bottom of the base plate 1. The pad plate 2 is set at the bottom of the base plate 1. The rubber layer 4 is provided with a groove 5 that matches the pad plate 2. The side of the pad plate 2 away from the base plate 1 is used to abut against the vehicle body and to connect and fix it to the vehicle body.

[0024] By covering the base plate 1 with a rubber layer 4, the rubber layer 4 is located between the base plate 1 and the pad plate 2 after the base plate 1 is connected. The pad plate 2 is fixedly connected to the vehicle body, thus achieving a soft connection between the base plate 1 and the vehicle body. This can play a buffering and shock-absorbing role during vehicle operation, effectively reducing the sound transmitted from the tailgate lock during vehicle operation and achieving a better noise reduction effect.

[0025] like Figure 1 and Figure 2 As shown, vertical columns 6 are integrally formed with the base plate 1 on opposite sides. Rubber buffer blocks 7 are detachably fitted onto the columns 6. The rubber buffer blocks 7 have insertion holes 8 that are compatible with the columns 6. Installation is achieved by vertically inserting the rubber buffer blocks 7 into the columns 6 through the insertion holes 8. Disassembly is possible by simply lifting the rubber buffer blocks 7 upwards. The surface of the rubber buffer block 7 facing the central retaining ring 3 has an abutment surface 9 for abutting the lock body. That is, when the tailgate is closed, the lock body and retaining ring 3 cooperate to achieve locking. The two side walls of the lock body abut against the contact surface 9 of the side wall of the rubber buffer block 7, thereby achieving a buffering effect when the tailgate closes, reducing the impact noise generated when the tailgate closes, and also effectively mitigating the impact between the lock body and the latch, extending the service life of the lock body and the latch. In addition, the rubber buffer block 7 is independently detachable, and can be disassembled and replaced separately when wear occurs after long-term use. Disassembly and replacement are simple and convenient. An extended flange 10 is provided on the outer edge of the bottom of the rubber buffer block 7. The design of the flange 10 makes it easy to disassemble and install by hand.

[0026] like Figure 5As shown, an anti-detachment part 11 is provided at the top of the column 6. The anti-detachment part 11, the column 6, and the base plate 1 are integrally formed. The width of the anti-detachment part 11 is greater than the width of the column 6. The width of the anti-detachment part 11 gradually increases from the top to the bottom. In this way, after the column 6 and the rubber buffer block 7 are inserted and matched, the anti-detachment part 11 can play a good anti-detachment effect, thereby improving the installation firmness of the rubber buffer block 7 and making it less likely for the rubber buffer block 7 to loosen.

[0027] like Figure 1 , Figure 4 and Figure 5 As shown, symmetrical through-holes 12 are provided on the base plate 1 for connection and fixation. The through-holes 12 penetrate the base plate 1 and the rubber layer 4. In actual use, the entire lock is fixed to the vehicle body by fasteners such as screws through the through-holes 12. The base plate 1 has a recessed portion 13 around the through-holes 12. The rubber layer 4 has a protrusion 14 that matches the recessed portion 13. That is, after the rubber layer 4 covers the base plate 1, the protrusion 14 fills the recessed portion 13. This can effectively improve the firmness and stability of the rubber layer 4 covering the base plate 1, making it less likely for the rubber layer 4 to move relative to the base plate 1.

[0028] like Figure 1 and Figure 4 As shown, a positioning ring 15 protrudes from the pad 2 and is inserted into the connecting hole 12. A bushing 16 is provided on the side of the rubber layer 4 facing away from the pad 2. The surface of the rubber layer 4 has a positioning groove 17 that fits the bushing 16. After the bushing 16 is installed in the positioning groove 17, it is connected and fixed by an interference fit with the positioning ring 15. Both the bushing 16 and the positioning ring 15 are hollow in the center to allow fasteners used for connection and fixation to pass through. By using the interference fit between the bushing 16 and the positioning ring 15 for connection and fixation, the rubber layer 4 can be pressed tightly against the base plate 1, thus... The connection between the two is tighter, and they are less likely to move relative to each other. On the other hand, the connecting hole 12 formed in the center of the bushing 16 and the positioning ring 15 allows fasteners to pass through. When fasteners are inserted for fixation, they make hard contact with the inner wall of the bushing 16 and the positioning ring 15, which is less likely to damage the rubber layer 4 and protects the rubber layer 4, thus realizing the multi-purpose function of the bushing 16. The bushing 16 has a tapered guide surface 22, which is used to guide the fasteners and facilitate the fasteners to pass into the connecting hole 12.

[0029] like Figure 1 and Figure 3 As shown, symmetrically arranged positioning holes 18 are provided on the base plate 1. The positioning holes 18 are located on opposite sides of the buckle 3. The positioning holes 18 facilitate positioning when the base plate 1 is covered with the rubber layer 4, ensuring that the base plate 1 will not shift during the rubber covering process and guaranteeing the quality of the rubber covering.

[0030] like Figure 1As shown, there are protruding edges 19 on both sides of the rubber layer 4. The protruding edges 19 are located below the flange 10 on the rubber buffer block 7. The protrusion 14 is used to abut against and support the flange 10. In this way, the protruding edges 19 can play an auxiliary support role for the rubber buffer block 7, and also play a role in limiting the vertical stroke. After the protruding edges 19 contact the flange 10, it means that the rubber buffer block 7 has been vertically inserted and installed in place.

[0031] like Figure 2 As shown, the pad 2 has a clearance part 20 in the middle to avoid the end of the buckle 3. The clearance part 20 effectively avoids interference between the pad 2 and the buckle 3, ensuring that the pad 2 can be installed smoothly, and also facilitates the subsequent disassembly of the buckle 3. The bottom surface of the pad 2 has an anti-slip texture 21, which can increase the friction resistance and thus improve the stability of the pad 2 when installed on the vehicle body.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
