The mudguards used for installation in the prior art all use screws or other fixing parts to fix the mudguards on the car body or the rear fork structure of the electric motorcycle, so that the mudguards block the rear wheel. After long-term use, more mud will adhere to the mudguards, and the users need to remove the mudguards from the rear fork structure. However, when removing the mudguards, the users need to use other tools to operate the mudguards, which is not convenient for quick removal and installation of the mudguards, affecting the cleaning of the mudguards. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an electric motorcycle rear fork structure, which can facilitate the disassembly of the mudguard without the need for other tools.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: an electric motorcycle rear fork structure, comprising a rear fork bracket and a rear wheel arranged on the rear fork bracket, the rear fork bracket being detachably connected with a mudguard, the mudguard being located directly above the rear wheel, two groups of connecting rods being symmetrically arranged at one end of the mudguard close to the rear fork bracket, the two groups of connecting rods being slidably connected to the mudguard, a sliding cavity for sliding of the connecting rods is provided inside the mudguard, connecting blocks are protrudingly provided at one end of the two groups of connecting rods close to the rear fork bracket, a first spring is abutted between the two groups of connecting rods, a fixing seat is fixedly connected to one end of the rear fork bracket close to the mudguard, a slot for inserting the connecting rod is provided inside the fixing seat, a slot for inserting the connecting rod is provided on the side wall of the slot, and the slot is communicated with the outside.

[0006] By adopting the above technical solution, the mudguard on the rear fork bracket is used to block the rear wheel of the electric motorcycle. After the electric motorcycle is used for a long time, a lot of mud and dirt adhere to the mudguard, and the user needs to continue to remove the mudguard for cleaning or repair and replacement. The user needs to press the connecting block protruding on the rear fork bracket to retract the connecting block into the slot through the card slot, and then pull the connecting rod until the connecting rod slides out of the slot, and then release the pressing force on the connecting rod, so that the first spring between the two connecting rods drives the connecting rod to return to the initial state, so that the operation of removing the mudguard can be realized, and after waiting for the mudguard to be cleaned, the user can remove the mudguard. After that, the mudguard needs to be installed on the rear fork bracket. The user first presses the two connecting rods to make the first spring between the two connecting rods shrink due to the external force, and then inserts the connecting rod and the connecting block into the slot opened in the fixing seat. After the connecting block moves to the position corresponding to the slot, the external force on the connecting rod is removed, and the first spring will gradually return to its initial state and push the connecting rod, so that the connecting rod fits with the inner wall of the slot, and the connecting block will be stuck in the slot to be fixed. The mudguard is fixed on the rear fork bracket by fixing the connecting rod, which is convenient for blocking the mud and water splashed by the rear wheel and prolonging the service life of the mudguard.

[0010] By adopting the above technical solution, the limit block will slide along the inner wall of the limit groove as the protruding block slides, further limiting the sliding trajectory of the protruding block to ensure the stability of the protruding block and the connecting rod when sliding. The limit block not only plays a limiting role, but also plays a certain supporting role, so that the protruding block and the connecting rod will not fall off the fender when they move in the fender, and when the connecting rods approach each other, the width of the limit block is wide enough and will not fall off the limit groove, and the user does not need to press the connecting block protruding out of the slot with one hand, and hold the connecting rod with one hand to drive the connecting block and the connecting rod to separate from the slot, which facilitates the user's operation.

[0011] The utility model is further configured as follows: first magnetic blocks are arranged at both ends of the limit block, a second magnetic block which is attracted to the first magnetic block is arranged in the limit groove, and two second magnetic blocks are arranged symmetrically in the limit groove.

[0012] By adopting the above technical solution, when the extending block slides in the slide groove and slides to the two ends of the slide groove, the extending block needs to be fixed, and as the extending block slides, the limit block will contact the second magnetic blocks at the two ends respectively, and the first magnetic block on the limit block will be adsorbed with the second magnetic block to achieve the fixation of the limit block and the extending block. At the same time, the connecting rod can be fixed in the mudguard and will not be easily separated, which is also convenient for users to take and remove the mudguard.

[0013] The utility model is further configured as follows: a limiting sleeve is provided on the outer side of the first spring, and the limiting sleeve comprises a first fixing sleeve and a second fixing sleeve which are slidably connected to each other.

[0014] By adopting the above technical solution, when the first spring is extended and shortened, the first fixing sleeve and the second fixing sleeve will slide against each other on the outside of the first spring, thereby protecting the first spring and preventing the first spring from being significantly bent, thereby ensuring the use effect of the first spring and the service life of the first spring.

[0015] The utility model is further configured as follows: fixing blocks that block each other are provided at the ends of the first fixing sleeve and the second fixing sleeve that are close to each other.

[0016] By adopting the above technical solution, when the first fixing sleeve and the second fixing sleeve slide against each other, the fixing blocks will block each other to prevent the first fixing sleeve and the second fixing sleeve from separating, thereby ensuring the protective effect of the limiting sleeve on the first spring.

[0017] The utility model is further configured as follows: a plurality of second springs distributed in an array are arranged between the two connecting rods.

[0018] By adopting the above technical solution, the second springs play a certain supporting and elastic role, preventing the support strength of the two connecting rods from being reduced due to the effect of only one first spring, and ensuring the elastic strength of the first spring and the second spring.

[0019] To sum up, the utility model has the following beneficial effects: the user presses the connecting block protruding from the rear fork bracket so that the connecting block retracts into the slot through the card slot, and then pulls the connecting rod until the connecting rod slides out of the slot, and then releases the pressing force on the connecting rod, so that the first spring between the two connecting rods drives the connecting rod to return to its initial state, so that the mudguard can be removed, and the structure is simple and convenient for the staff to operate, and it is also convenient for the staff to reinstall the mudguard on the rear fork bracket.
