Description

Technical Field

[0001] This utility model relates to the field of automotive tailgate rubber parts, specifically an automotive tailgate rubber part. Background Technology

[0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformations under small external forces. It can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and a very large molecular weight, often exceeding hundreds of thousands. Rubber products are widely used in various aspects of industry and daily life. Rubber blocks are often installed on car tailgates to protect them.

[0003] The existing thickened rubber blocks on the tailgates of auto parts trucks are installed using multiple sets of bolts, which are repeatedly tightened with tools. This thickened design gives the rubber blocks stronger impact resistance. When the tailgate collides with an external object, it can effectively absorb and disperse the impact force, thereby reducing damage to the tailgate and cargo. By reducing damage to the tailgate during an impact, the rubber blocks help maintain the integrity and stability of the tailgate, thus improving the safety of the truck during driving.

[0004] The aforementioned rubber blocks still have the following shortcomings: during installation, additional tools are required to repeatedly fix the bolts inside the rubber blocks, making the installation process very cumbersome. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a rubber part for a car tailgate to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tailgate rubber component for automobiles, comprising a tailgate shell and a rubber block. A limit block is fixedly installed at the top of the tailgate shell, and a fixing post is slidably installed inside the rubber block. A first sliding groove corresponding to the limit block is opened inside the fixing post, and a second sliding groove is opened inside the fixing post. A limit ring is fixedly installed inside the second sliding groove. A limit sleeve is slidably installed inside the fixing post, and a third sliding groove corresponding to the limit sleeve is opened inside the fixing post. A limit groove corresponding to the limit sleeve is opened at the top of the limit block, and a spring is fixedly installed at the top of the limit sleeve.

[0007] By adopting the above technical solution, pressing the pressure plate causes the limiting block to slide into the first groove of the fixing column, thus completing the installation of the rubber block. This is convenient and quick, requiring no additional tools. Under the action of the first groove, the limiting block is squeezed inward. After the limiting block enters the second groove, the pressure on the limiting block disappears, thereby resetting and forming a locking structure with the second groove, thus fixing the rubber block. Further, a limiting ring, a limiting sleeve, a third groove, a limiting groove, a spring, and a fourth groove are provided. Pressing the pressure plate again causes the limiting ring to squeeze the limiting block, causing the limiting sleeve to lock into the limiting groove of the limiting block. Then, under the push of the spring, the locking structure between the limiting block and the second groove is released, thus completing the disassembly of the rubber block.

[0008] Furthermore, multiple sets of the fixing columns are slidably installed inside the rubber block, and pressure plates are fixedly installed at the top of the multiple sets of fixing columns. A fourth sliding groove corresponding to the pressure plate is opened at the top of the rubber block.

[0009] By adopting the above technical solution, all the fixed columns at the bottom of the pressure plate can be limited and installed at one time through the pressure plate.

[0010] Furthermore, multiple sets of the limiting blocks are fixedly installed on the outer wall of the car tailgate shell, and each set of limiting blocks consists of multiple sets of limiting blocks installed at equal intervals, and the limiting blocks are designed in an inverted L shape.

[0011] By adopting the above technical solution, the inverted L-shaped limit block can form an engaging structure with the second slide groove for limit installation. By setting multiple sets, the fixing effect of the limit is further improved.

[0012] Furthermore, the top outer wall of the limiting block is designed with a slope, and the limiting block is an elastic rubber part, and the limiting block is designed to be tilted 2° towards the rubber block.

[0013] By adopting the above technical solution, the first slide can be slidably installed with the limit block through the inclined surface at the top of the limit block, and squeeze the limit block.

[0014] Furthermore, the second slide groove is formed above the first slide groove, and the second slide groove communicates with the first slide groove, and the outer diameter of the second slide groove is larger than the outer diameter of the first slide groove.

[0015] By adopting the above technical solution, after the first slide groove squeezes the limiting block, the limiting block will be squeezed into the second slide groove and then reset and spring back, thus easily forming a limiting engagement structure.

[0016] Furthermore, the third slide groove is installed above the second slide groove and communicates with the second slide groove, and the outer diameter of the third slide groove is smaller than the inner diameter of the limiting ring.

[0017] By adopting the above technical solution, the bottom end of the limiting sleeve can slide into the second groove.

[0018] Furthermore, the other end of the spring is fixedly connected to the inner wall of the third slide groove, and the inner diameter of the limiting sleeve is greater than the minimum inner diameter of the top of the limiting block.

[0019] By adopting the above technical solution, the spring can push the limiting sleeve to reset. At the same time, before the limiting sleeve is locked into the limiting groove, it will be pushed by the top of the limiting block and squeeze the spring.

[0020] In summary, the present invention has the following main advantages:

[0021] This utility model, by setting a limiting block, a fixing post, a first sliding groove, a second sliding groove, and a pressure plate, allows for easy and quick installation of the rubber block. When installing the rubber block, pressing the pressure plate causes the limiting block to slide into the first sliding groove of the fixing post, thus completing the installation without the need for additional tools. The first sliding groove presses the limiting block inwards, and once it enters the second sliding groove, the pressure on the limiting block disappears, allowing it to reset and form a locking structure with the second sliding groove, thus fixing the rubber block. Further, a limiting ring, a limiting sleeve, a third sliding groove, a limiting groove, a spring, and a fourth sliding groove are provided. Pressing the pressure plate again causes the limiting ring to press against the limiting block, causing the limiting sleeve to lock into the limiting groove of the limiting block. Then, under the push of the spring, the locking structure between the limiting block and the second sliding groove is released, allowing for the removal of the rubber block.

[0022] The parts of this device not covered herein are the same as or can be implemented using existing technology. This utility model enables rubber blocks to be quickly installed, disassembled, or replaced without the aid of tools. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] A type of rubber part for automotive tailgates, such as Figure 1 - Figure 5 As shown, the device includes a tailgate shell 1 and a rubber block 2. The rubber block 2 is installed on the tailgate shell 1 for impact protection. A limiting block 3 is fixedly installed at the top of the tailgate shell 1. The rubber block 2 is installed through the limiting block 3, and a fixing post 4 is slidably installed inside the rubber block 2. The fixing post 4 has a first sliding groove 5 corresponding to the limiting block 3. The limiting block 3 is engaged in the first sliding groove 5, and the installation of the rubber block 2 through the first sliding groove 5 and the fixing post 4 limits its position. A second sliding groove 5 is also provided inside the fixing post 4. The groove 6, the second sliding groove 6 and the limiting block 3 form a locking structure, and a limiting ring 7 is fixedly installed in the second sliding groove 6. The limiting ring 7 can squeeze the limiting block 3. A limiting sleeve 8 is slidably installed in the fixing column 4, and a third sliding groove 9 corresponding to the limiting sleeve 8 is opened in the fixing column 4. A limiting groove 10 corresponding to the limiting sleeve 8 is opened at the top of the limiting block 3. The limiting sleeve 8 is locked into the limiting groove 10 to form a limit. A spring 11 is fixedly installed at the top of the limiting sleeve 8.

[0032] Please see Figure 2 , Figure 4 and Figure 5 Multiple sets of fixing posts 4 are slidably installed inside the rubber block 2, and pressure plates 12 are fixedly installed on the top of the multiple sets of fixing posts 4. The top of the rubber block 2 is provided with a fourth sliding groove 13 corresponding to the pressure plate 12, so that all the fixing posts 4 at the bottom of the pressure plate 12 can be limited and installed at one time through the pressure plate 12.

[0033] Please see Figure 3 Multiple sets of limiting blocks 3 are fixedly installed on the outer wall of the tailgate shell 1. Each set of limiting blocks 3 consists of multiple sets of limiting blocks 3 installed at equal intervals. The limiting blocks 3 are designed in an inverted L shape, so that the inverted L shape of the limiting blocks 3 can form a locking structure with the second slide groove 6 for limiting installation. By setting multiple sets, the fixing effect of limiting is further improved.

[0034] Please see Figure 3 The top outer wall of the limiting block 3 is designed with a slope, and the limiting block 3 is an elastic rubber part. The limiting block 3 is designed to be inclined at 2° towards the rubber block 2, so that the first sliding groove 5 can slide and install with the limiting block 3 through the slope of the top of the limiting block 3 and squeeze the limiting block 3.

[0035] Please see Figure 4 The second slide 6 is located above the first slide 5 and is connected to the first slide 5. The outer diameter of the second slide 6 is larger than that of the first slide 5, so that after the first slide 5 presses the limiting block 3, the limiting block 3 will be reset and spring back after being pressed into the second slide 6, thus easily forming a limiting engagement structure.

[0036] Please see Figure 4 The third slide groove 9 is installed above the second slide groove 6 and is connected to the second slide groove 6. The outer diameter of the third slide groove 9 is smaller than the inner diameter of the limiting ring 7, so that the bottom end of the limiting sleeve 8 can slide into the second slide groove 6.

[0037] Please see Figure 2 and Figure 4 The other end of the spring 11 is fixedly connected to the inner wall of the third slide groove 9, and the inner diameter of the limiting sleeve 8 is greater than the minimum inner diameter of the top of the limiting block 3, so that the spring 11 can push the limiting sleeve 8 to reset. At the same time, before the limiting sleeve 8 is inserted into the limiting groove 10, it will be pushed by the top of the limiting block 3 to squeeze the spring 11.

[0038] The working principle of this utility model is as follows: When installing the rubber block 2, the rubber block 2 and the limiting block 3 are slidably installed. The pressure plate 12 is pressed, causing the limiting block 3 to slide into the first groove 5 of the bottom fixing post 4 of the pressure plate 12. At the same time, the first groove 5 squeezes the limiting block 3, causing the limiting block 3 to rotate away from the rubber block 2. When the limiting block 3 slides into the second groove 6, the squeezing effect of the first groove 5 on the limiting block 3 disappears. After the limiting block 3 is reset, it forms a locking structure with the second groove 6, thus completing the installation and fixing of the rubber block 2.

[0039] When it is necessary to disassemble the rubber block 2, press the pressure plate 12 again. When the pressure plate 12 pushes the fixing post 4 to slide downward, the limiting block 3 will push the limiting sleeve 8 to slide towards the spring 11 and squeeze the spring 11. When the fixing post 4 slides to the limiting ring 7 to squeeze the limiting block 3, the limiting sleeve 8 will be inserted into the limiting groove 10 as the limiting block 3 is squeezed and rotated, thus limiting the limiting block 3. When the pressure plate 12 is pressed to the bottom of the fourth slide groove 13, release the pressure plate 12. The spring 11 will start to reset and push the limiting sleeve 8, thereby causing the rubber block 2 to slide away from the car tailgate shell 1. After the spring 11 is fully reset, the locking structure between the limiting block 3 and the second slide groove 6 can be released, thus completing the disassembly of the rubber block 2.
