DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0033] Combination Figure 1-3The utility model is a shock absorbing device for electric vehicles for preventing spring deformation, comprising two protective tubes 3, a shock absorbing shaft 20 is arranged inside the protective tube 3, a thread 9 is provided on the inner wall of the protective tube 3, a thread 2 is provided on the outer wall of the shock absorbing shaft 20, a moving block 19 is threadedly connected to the outer wall of the thread 2 10, a shock absorbing spring 18 is fixedly connected between the moving block 19 and the shock absorbing shaft 20, a movable plate 11 is threadedly connected to the outer wall of the thread 9, a fixed block 13 is fixedly connected to the upper and lower sides of the movable plate 11, and a uniformly distributed hair is fixedly connected to the inner side of the movable plate 11 The bottom of the fixed block 13 is fixedly connected with a connecting rod 14, and the connecting rod 14 penetrates the fixed block 13 and extends into the interior of the fixed block 13. The other end of the connecting rod 14 is fixedly connected with a pull plate 5. If mud and dirt enter through the connection between the connecting column 2 and the protective tube 3 and adhere to the surface of the shock-absorbing spring 18, the user puts the electric vehicle down and pulls the pull plate 5 to make the connecting rod 14 drive the movable plate 11 to rotate and reciprocate inside the protective tube 3, which correspondingly drives the inner brush to clean the surface of the shock-absorbing spring 18, thereby maintaining the cleanliness of the surface of the shock-absorbing spring 18.

[0034] Combination Figure 1 and Figure 4 A disassembly assembly is provided at the bottom of the protective cylinder 3, and the disassembly assembly includes a movable cylinder 4, which is fixedly connected to the bottom of the protective cylinder 3. The movable cylinder 4 is slidably connected to the connecting rod 14, and the connecting rod 14 penetrates the connecting rod 14 and extends to the upper and lower sides of the movable cylinder 4. The outer wall of the movable cylinder 4 is threadedly connected with movable bolts 8 distributed opposite to each other on both sides, and the movable bolts 8 penetrate the movable cylinder 4 and extend into the interior of the movable cylinder 4. The bottom of the shock absorber shaft 20 is fixedly connected with a connecting block 15, and the connecting block 15 penetrates the movable cylinder 4 and extends into the interior of the movable cylinder 4. Grooves 16 are provided on both sides of the outer wall of the connecting block 15, and one end of the movable bolt 8 is fixed A clamping block 17 is connected, and the clamping block 17 is engaged with the groove 16. After long-term use, a large amount of mud and dirt adheres to the surface of the brush 12. At this time, the cleaning ability of the brush 12 is reduced, and there is also a risk of covering the mud and dirt back to the shock-absorbing spring 18. At this time, the user pulls the movable plate 11 to the inside of the movable cylinder 4, and then loosens the two movable cylinders 4 to make the clamping block 17 at the end of the movable cylinder 4 disengage from the groove 16, so that the connecting block 15 is disengaged from the movable cylinder 4. At this time, the movable plate 11 can be removed together with the movable cylinder 4, and the user can clean or replace the brush 12, thereby ensuring the cleaning ability of the device.

[0035] Combination Figure 1 and Figure 4The two protective cylinders 3 are fixedly connected to a rotating shaft 7 on one side of the outer wall close to each other, and a wheel 6 is rotatably connected between the two rotating shafts 7. The top of the shock-absorbing shaft 20 is fixedly connected to a connecting column 2, and the connecting column 2 and the protective cylinder 3 are slidably connected. The top of the connecting column 2 is fixedly connected to a mounting block 1, and the device is installed at a suitable position on the front half of the electric vehicle through the mounting block 1. During use, the protective cylinder 3 isolates the shock-absorbing spring 18 and the shock-absorbing shaft 20 used for shock absorption of the device from the outside world, thereby greatly reducing the splashing of some mud and dirt on the shock-absorbing component in daily use, and also preventing the shock-absorbing component from being accidentally touched by the outside world, thereby extending the service life of the device.

[0036] Working principle: before use, the user first conducts a comprehensive inspection of the device to ensure that the device is complete and has no damage. Then, the user installs the device at a suitable position on the front half of the electric vehicle through the mounting block 1. During use, the protective tube 3 isolates the shock-absorbing spring 18 and the shock-absorbing shaft 20 used for shock absorption of the device from the outside world, thereby greatly reducing the splashing of mud and dirt on the shock-absorbing component in daily use, and also preventing the shock-absorbing component from being accidentally touched by the outside world, thereby extending the service life of the device. At the same time, if mud and dirt enter through the connection between the connecting column 2 and the protective tube 3 and adhere to the surface of the shock-absorbing spring 18, the user puts the electric vehicle down and pulls the pull plate 5 so that the connecting rod 14 drives the movable plate 11 in the protective tube. The protective tube 3 rotates and reciprocates inside, which correspondingly drives the inner brush to clean the outer surface of the shock-absorbing spring 18, thereby maintaining the cleanliness of the outer surface of the shock-absorbing spring 18. After long-term use, a large amount of mud and dirt adheres to the surface of the brush 12. At this time, the cleaning ability of the brush 12 decreases, and there is also a risk of covering the shock-absorbing spring 18 with mud and dirt. At this time, the user pulls the movable plate 11 to the inside of the movable cylinder 4, and then loosens the two movable cylinders 4, so that the block 17 at the end of the movable cylinder 4 is disengaged from the groove 16, thereby disengaging the connecting block 15 from the movable cylinder 4. At this time, the movable plate 11 can be removed together with the movable cylinder 4, and the user can clean or replace the brush 12, thereby ensuring the cleaning ability of the device.
