Description

Technical Field

[0001] The utility model belongs to the technical field of automotive parts, and particularly relates to a rear fender seal assembly for new energy vehicles. Background Art

[0002] The rear fender seal, also known as the rear wheel arch seal or the rear wheel arch inner lining, is a panel installed inside the rear wheel arch of a vehicle. Its main functions include protecting the vehicle body structure, reducing noise and vibration, and improving aerodynamic performance. The rear fender seal is usually fixed by three methods: snap fixation, screw fixation, and adhesive fixation. Usually, the corresponding installation method is adopted according to the design of the rear fender seal.

[0003] When the rear fender seal is fixed by bolts, due to the short threaded section of the bolts, various vibrations during vehicle driving will cause the bolts to loosen, resulting in the rear fender seal falling off, affecting the protection of the vehicle. Summary of the Utility Model

[0004] In view of the problem that the bolts will loosen due to the vibration during vehicle driving and cause the rear fender seal to fall off in the prior art, the utility model proposes the following technical solutions:

[0005] A rear fender seal assembly for new energy vehicles includes a rear seal main body and a plurality of bolt seats. The plurality of bolt seats are integrally formed with the rear seal main body. A fixing component is arranged inside the bolt seat. The fixing component includes a fixing bolt, a mounting block, and a dismounting part. Two limiting blocks are movably inserted at the bottom of the mounting block. A return spring is fixedly connected between the two limiting blocks. A plugging groove is formed on the inner surface of the bolt seat. One end of the limiting block is movably inserted into the plugging groove.

[0006] Preferably, the dismounting part includes a pressing block and an elastic ring. The two ends of the pressing block are in contact with the two limiting blocks. The elastic ring is fixedly connected to the bottom of the mounting block.

[0007] Preferably, two resisting blocks are fixedly connected to the bottom of the pressing block, and the two resisting blocks are respectively located on both sides of the return spring.

[0008] Preferably, the middle part of the elastic ring is hollow, and the strength of the elastic ring is 3-5 times that of the return spring.

[0009] Preferably, both ends of the pressing block are provided with slopes, and the contact part between the limiting block and the pressing block is matched with the pressing block.

[0010] The beneficial effects of the utility model are as follows:

[0011] 1. The cooperation between the limit block and the insertion slot is used to fix the installation block in the bolt seat, which can block the moving direction of the fixing bolt, prevent the fixing bolt from loosening due to the vibration during vehicle driving, thus ensuring the protection of the vehicle by the rear fender back panel. Moreover, the installation block can shield the fixing bolt, reduce the influence of external factors on the fixing bolt, and ensure the normal use of the fixing bolt.

[0012] 2. The provided disassembly part can contract the limit block to disconnect the fixation of the installation block. Due to the high strength of the elastic ring, the installation block is pushed outwards from the bolt seat, thus facilitating the removal of the fixing component and making it more convenient to use.

[0017] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings of the description.

[0018] Embodiment

[0019] Figures 1-3 In the embodiment, the rear fender back panel assembly of a new energy vehicle includes a rear fender back panel main body 10 and a plurality of bolt seats 20. The plurality of bolt seats 20 are integrally formed with the rear fender back panel main body 10. A fixing component is arranged inside the bolt seat 20. The fixing component includes a fixing bolt 31, an installation block 32 and a disassembly part 36. Two limit blocks 33 are movably inserted at the bottom of the installation block 32. A return spring 34 is fixedly connected between the two limit blocks 33. An insertion slot 35 is formed on the inner surface of the bolt seat 20. One end of the limit block 33 is movably inserted into the insertion slot 35.

[0020] The cooperation of the limit block 33 and the insertion slot 35 is used to fix the mounting block 32 in the bolt seat 20, which can block the moving direction of the fixing bolt 31, prevent the fixing bolt 31 from loosening due to the vibration during the driving of the vehicle, thus ensuring the protection of the vehicle by the rear fender seal plate. Moreover, the mounting block 32 can shield the fixing bolt 31, reduce the influence of external factors on the fixing bolt 31, and ensure the normal use of the fixing bolt 31.

[0021] Figures 2-3 Among them, the disassembly part 36 includes a pressing block 361 and an elastic ring 362. Both ends of the pressing block 361 are in contact with the two limit blocks 33, and the elastic ring 362 is fixedly connected to the bottom of the mounting block 32.

[0022] The middle part of the elastic ring 362 is hollow, and the strength of the elastic ring 362 is 3 - 5 times that of the return spring 34.

[0023] The provided disassembly part 36 can contract the limit block 33 to disconnect the fixation of the mounting block 32. Due to the high strength of the elastic ring 362, the mounting block 32 is pushed outwards from the bolt seat 20, thus facilitating the removal of the fixing component and making it more convenient to use.

[0024] Figure 3 Among them, both ends of the pressing block 361 are provided with slopes, and the contact part with the limit block 33 matches the pressing block 361.

[0025] The pressing block 361 with slopes at both ends can move the limit block 33 with slopes at both ends in the direction perpendicular to the force application direction during movement, so as to push the two limit blocks 33 towards each other and contract them.

[0026] Two resisting blocks 363 are fixedly connected to the bottom of the pressing block 361, and the two resisting blocks 363 are respectively located on both sides of the return spring 34.

[0027] The resisting block 363 can block the movement of the pressing block 361. The pressing block 361 and the fixing bolt 31 are regarded as a whole relative to each other through the resisting block 363, ensuring the normal movement of the mounting block 32 so as not to affect the detachment of the mounting block 32.

[0028] Working principle: When installing the rear sealing plate main body 10, first install the fixing bolt 31 into the bolt seat 20 to fix the rear sealing plate main body 10. Then, press the two limit blocks 33 to make them in a contracted state and install the installation block 32 into the bolt seat 20. When the limit block 33 moves to the position of the insertion slot 35, the return spring 34 in a compressed state resets the limit block 33 to insert it into the insertion slot 35, thereby blocking the path of the fixing bolt 31 and preventing the fixing bolt 31 from falling off. When disassembling the rear sealing plate main body 10, since both ends of the pressing block 361 are provided with slopes and the contact surface with the limit block 33 matches the pressing block 361, push the pressing block 361 to make the two limit blocks 33 contract inward and leave the insertion slot 35. After the blocking block 363 contacts the fixing bolt 31, since the strength of the elastic ring 362 is 3-5 times that of the return spring 34, the elastic ring 362 pushes the installation block 32 outwards. During this process, the limit block 33 continues to contract inward and continues to compress the return spring 34. After releasing the pressing block 361, the reset process of the limit block 33 is blocked by the inner wall of the bolt seat 20, and part of the installation block 32 moves out of the bolt seat 20, facilitating the removal of the installation block 32. Then, the fixing bolt 31 can be removed.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them.
