[0002] In the daily use of electric motorcycles, mudguards are an indispensable component. Their main function is to block mud and water splashed up by the wheels during driving, protecting the motorcycle body and rider from mud and dirt.

[0003] The common installation method for existing mudguards is bolt fastening. This method requires tools to fix the mudguard to a specific part of the locomotive with multiple bolts. The installation process is cumbersome, which not only consumes a certain amount of time and effort, but also, if the bolts are tightened unevenly during the installation process, it is easy to cause the mudguard to be installed crookedly, affecting the mud-blocking effect. When the mudguard needs to be cleaned, repaired or replaced in the future, it is necessary to unscrew each bolt one by one, which is extremely inconvenient. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a flexible shock-absorbing mudguard for electric locomotives. This solves the problem that fixing the mudguard to a specific part of the locomotive with multiple bolts is a cumbersome installation process that not only requires a certain amount of time and effort, but also that if the bolts are tightened inconsistently during the installation process, it is easy to cause the mudguard to be installed crookedly, affecting the mud-blocking effect. Furthermore, when the mudguard needs to be cleaned, repaired or replaced in the future, it is necessary to unscrew each bolt one by one, which is extremely inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible shock-absorbing mudguard for electric locomotives, comprising a mudguard, two connecting and fixing rods and two movable rods, wherein a limit device is provided on the mudguard;

[0006] The limiting device includes two mounting blocks and two protective shells. The two protective shells are fixedly connected to the corresponding mounting blocks. Both outer walls of the mudguard are fixedly connected to protrusions. One outer wall of each of the two mounting blocks is provided with a protrusion groove. Both outer walls of the mudguard are fixedly connected to two conical blocks.

[0007] Each of the two mounting blocks has two conical block grooves on one side of its outer wall, and each of the two protrusions has a second limiting block groove on one side of its outer wall. Each of the two protrusion grooves has a first limiting block groove inside it. Each of the two first limiting block grooves has a limiting block slidably connected inside it. Each of the two protective shells has a pull rod slidably connected to its outer wall, and each of the two pull rods has a return spring sleeved on its outer wall.

[0008] Preferably, the outer walls of the two protrusions are slidably connected to the interior of the corresponding protrusion groove;

[0009] The outer walls of the four conical blocks are slidably connected to the interior of the corresponding conical block grooves.

[0010] Preferably, the ends of the two limiting blocks near the second limiting block grooves both slide into the interior of the protrusion grooves and respectively contact the inner wall of the corresponding second limiting block grooves;

[0011] The interiors of the two protective shells are respectively connected to the interiors of the corresponding first limiting block grooves.

[0012] Preferably, the ends of the two pull rods near the limiting block both slide into the interior of the first limiting block groove and are respectively fixedly connected to one end of the corresponding limiting block;

[0013] The two ends of the two reset springs are fixedly connected to the outer wall of one end of the corresponding limit block and the inner wall of the first limit block groove, respectively.

[0014] Preferably, one end of each of the two movable rods is connected to one end of a corresponding connecting fixed rod by bolts.

[0015] Preferably, the ends of the two mounting blocks furthest from the mudguard are connected to the ends of the corresponding movable rods furthest from the connecting fixed rods by bolts.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The flexible shock-absorbing mudguard of this electric locomotive can be removed by pulling the pull rod on the protective shell through the limiting device. The pull rod drives the limiting block to compress the reset spring, so that the limiting block disengages from the second limiting block groove of the protrusion, thereby releasing the locking of the mudguard. Then, the mudguard can be removed from the mounting block by pulling it. This avoids the need for workers to use tools to remove the bolts one by one before removing the mudguard, effectively improving the maintenance and repair efficiency of the mudguard.

[0028] Please see Figure 1-4 This utility model provides a technical solution: a flexible shock-absorbing mudguard for electric locomotives, including a mudguard 5, two connecting and fixing rods 1 and two movable rods 2;

[0029] A limit device is provided on the mudguard 5;

[0030] The limiting device includes two mounting blocks 3 and two protective shells 4. The two protective shells 4 are fixedly connected to the corresponding mounting blocks 3. Protrusions 6 are fixedly connected to both outer walls of the mudguard 5. A protrusion groove 9 is formed on one outer wall of each of the two mounting blocks 3. The outer walls of the two protrusions 6 are slidably connected to the interior of the corresponding protrusion groove 9. Two conical blocks 13 are fixedly connected to both outer walls of the mudguard 5. Two conical block grooves 7 are formed on one outer wall of each of the two mounting blocks 3. The outer walls of the four conical blocks 13 are slidably connected to the interior of the corresponding conical block grooves 7. A second limiting block groove 14 is formed on one outer wall of each of the two protrusions 6. A first limiting block groove 10 is formed inside each of the two protrusion grooves 9. The interior of each of the two protective shells 4 is slidably connected to a limiting block 11. The ends of the two limiting blocks 11 near the second limiting block groove 14 are slidably extended into the interior of the protrusion groove 9 and respectively contact the inner wall of the corresponding second limiting block groove 14. The interior of each of the two protective shells 4 is connected to the interior of the corresponding first limiting block groove 10. The outer walls of each of the two protective shells 4 are slidably connected to a pull rod 8. The ends of the two pull rods 8 near the limiting block 11 are slidably extended into the interior of the first limiting block groove 10 and respectively fixedly connected to one end of the corresponding limiting block 11. The outer walls of each of the two pull rods 8 are sleeved with a return spring 12. The two ends of the two return springs 12 are respectively fixedly connected to one end of the outer wall of the corresponding limiting block 11 and the inner wall of the first limiting block groove 10.

[0031] Among them, one end of each of the two movable rods 2 is connected to one end of the corresponding connecting and fixing rod 1 by bolts, and the ends of the two mounting blocks 3 away from the mudguard 5 are connected to the ends of the corresponding movable rods 2 away from the connecting and fixing rod 1 by bolts.

[0032] Furthermore, when using this device, the mudguard 5 is first installed in the designated position via the connecting rod 1. Then, when the electric locomotive is moving, the road vibration is transmitted to the movable rod 2 via the connecting rod 1. In this way, the flexible connection between the movable rod 2, the mounting block 3, and the mudguard 5, combined with the flexible material of the mudguard itself, absorbs the vibration energy, reduces the impact of vibration on the mudguard, and ensures the normal operation of the mudguard. When it is necessary to remove the mudguard 5, pull the pull rod 8 on the protective shell 4. The pull rod 8 drives the limit block 11 to compress the reset spring 12, so that the limit block 11 disengages from the second limit block groove 14 of the protrusion 6, releasing the lock on the mudguard. Then, pull the mudguard 5 to remove it from the mounting block 3.

[0033] By pulling the lever 8 on the protective shell 4 through the limiting device, the lever 8 drives the limiting block 11 to compress the reset spring 12, causing the limiting block 11 to disengage from the second limiting block groove 14 of the protrusion 6, thus releasing the lock on the mudguard. Then, by pulling the mudguard 5, it can be removed from the mounting block 3. This avoids the need for workers to use tools to disassemble the bolts one by one before removing the mudguard 5, effectively improving the maintenance and repair efficiency of the mudguard 5.
