Description

Technical Field

[0001] This utility model belongs to the field of shock absorption technology for electric motorcycles, and in particular relates to a shock absorption structure for electric motorcycles. Background Technology

[0002] A shock-absorbing structure for electric motorcycles refers to an integrated system installed between the frame and wheels of an electric motorcycle, consisting of elastic elements, damping elements and their connections, and a transmission mechanism. Its core function is to actively absorb and dissipate the impact kinetic energy caused by uneven road surfaces, so as to continuously maintain the contact between the wheels and the ground, thereby ensuring the vehicle's handling stability, driving safety and riding comfort.

[0003] Most existing electric motorcycles use a shock absorption structure that consists of two dampers mounted on a double fork, along with springs, to achieve shock absorption and energy dissipation. However, after prolonged use, these dampers are prone to damage, requiring removal and replacement. Current dampers are typically connected to the double fork with multiple bolts, often requiring two workers to work together: one to hold the damper and align its mounting holes with the fork, and the other to install it. This makes it difficult for a single person to complete, and the lack of pre-connection structures during alignment often results in a lengthy process. Therefore, this method is cumbersome, time-consuming, and labor-intensive, leading to low maintenance efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a shock-absorbing structure for electric motorcycles. By setting up a disassembly and assembly mechanism, specifically, the bolts on the two mounting rings are first unscrewed, and the two rings are removed. Then, the damper is rotated counterclockwise to 90 degrees, causing the locking block to disengage from the two anti-rotation grooves. Next, the locking block on the new damper is inserted into the slot until the upper and lower round blocks contact each other. Then, the damper is rotated clockwise 90 degrees. Next, the two protrusions on the inner rings of the two mounting rings are inserted into the four locking grooves on the outer surfaces of the upper and lower round blocks respectively. Finally, the two mounting rings are fixed with bolts. This structure allows for quick disassembly and replacement of the damper, is simple and fast, and can be completed by a single person. It solves the problem that most existing dampers are connected to the double fork with bolts. During installation, two workers are needed to hold the damper to align its mounting holes with the double fork mounting holes while another worker performs the installation. This installation method is labor-intensive, time-consuming, and difficult for a single person to complete, and the alignment process takes a considerable amount of time, resulting in low installation efficiency.

[0008] Furthermore, the damping mechanism includes two springs respectively sleeved on the outside of the two dampers. The top of the damper is fixedly connected to the bottom of the lower circular block. The outer surface of the damper is slidably limited by a sleeve.

The top and bottom of the inner ring of the mounting ring are fixedly connected with arc edges. The upper arc edge is inserted into an annular groove. The inner ring of the mounting ring is fixedly connected with two protrusions. The two protrusions are respectively inserted into two corresponding locking grooves on the same side. The top of the lower arc edge is in contact with the bottom of the lower circular block.

[0011] Furthermore, the bottom output end of the damper one is fixedly connected to the bottom of the inner wall of the sleeve one, and the outer side of the output end of the damper one is fitted with a spring two.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model, through the setting of a disassembly and assembly mechanism, specifically involves first unscrewing the bolts on the two mounting rings and removing them, then rotating the damper one counterclockwise to 90 degrees to disengage the locking block from the two anti-rotation grooves, then inserting the locking block on the new damper one into the slot until the upper and lower round blocks contact each other, then rotating the damper one clockwise to 90 degrees, and then inserting the two protrusions on the inner rings of the two mounting rings into the four locking grooves on the outer surfaces of the upper and lower round blocks respectively, and finally fixing the two mounting rings with bolts. This structure allows for quick disassembly and assembly of the damper one for replacement and maintenance, is simple and fast, and can be completed by a single person.

[0015] 2. This utility model incorporates a shock-absorbing mechanism. Specifically, when the frame is subjected to bumps, the resulting downward pressure is transmitted to tripod one, causing it to move downwards. Since the two sleeves one are connected to the wheels and in contact with the ground, they cannot move downwards. Therefore, tripod one compresses damper two, which in turn causes the three sliding columns to press down, squeezing the corresponding spring three, causing it to contract and absorb energy, thus achieving initial shock absorption. Subsequently, the unabsorbed downward pressure is transmitted to tripod two, causing it to move downwards and compress the two dampers one, causing them to contract. The contraction of damper one also compresses spring two. Simultaneously, as the damper one moves downwards, it works in conjunction with sleeve one to compress spring one. This structure can effectively absorb the downward pressure on the frame caused by bumps through multiple shock-absorbing measures, achieving a good shock absorption effect.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The model also includes a disassembly and assembly mechanism 2. 2. A disassembly / assembly mechanism 2 is installed at the bottom of tripod 12 and the top of damper 31.

Four locking grooves 212 are opened on the outer surface of the upper circular blocks 21. A slot 22 and two anti-rotation grooves 221 are opened inside the upper circular blocks 21. The two anti-rotation grooves 221 are interconnected with the slots 22, and the position of the anti-rotation grooves 221 is higher than that of the slots 22. The damping mechanism 3 includes two springs 311 respectively sleeved on the outside of two dampers 31. The top of the damper 31 is fixedly connected to the bottom of the lower circular block 23. The outer surface of the damper 31 is slidably limited by a sleeve 32. One bottom end of the spring 311 is fixedly connected to the top of the sleeve 32. The locking block 232 is slidably limited by the slot 22 and rotatably connected to the anti-rotation groove 221. The outer surface of the lower circular block 23 has four locking grooves 212. The locking grooves 212 on the outer surface of the upper circular block 21 are the same as those on the outer surface of the lower circular block 23 and are interconnected.Two mounting rings 24 are provided on the outer surfaces of the upper circular block 21 and the lower circular block 23. The two mounting rings 24 are fixedly connected by several bolts. The top and bottom of the inner ring of the mounting ring 24 are fixedly connected with arc edges 241. The upper arc edge 241 is inserted into the annular groove 211. The inner ring of the mounting ring 24 is fixedly connected with two protrusions 242. The two protrusions 242 are respectively inserted into the two corresponding locking grooves 212 on the same side. First, unscrew the bolts on the two mounting rings 24 and remove them. Then, rotate the damper 31 counterclockwise to ninety degrees to make the locking block 232 disengage from the two anti-rotation grooves 212. 21. Then, insert the locking block 232 on the new damper 31 into the slot 22 until the upper round block 21 and the lower round block 23 are in contact. Then, rotate the damper 31 clockwise by 90 degrees. Next, insert the two protrusions 242 of the inner ring of the two mounting rings 24 into the four locking grooves 212 on the outer surface of the upper round block 21 and the lower round block 23 respectively. Finally, use bolts to fix the two mounting rings 24. This structure can quickly disassemble and replace the damper 31 for maintenance. It is simple and quick and can be completed by a single person. The top of the lower arc edge 241 is in contact with the bottom of the lower round block 23.

[0028] The bottom output end of damper 31 is fixedly connected to the bottom of the inner wall of sleeve 32. Spring 321 is sleeved on the outside of the output end of damper 31. One bottom end of spring 321 is fixedly connected to the bottom of the inner wall of sleeve 32, and one top end of spring 321 is fixedly connected to damper 31. Sleeve 32 is used to install and support spring 311 and to protect spring 321. A damper 2 33 is fixedly connected to the top of the lower connecting frame 112. The top of the output end of the damper 2 33 is fixedly connected to the bottom of the upper connecting frame 112. A sliding column 34 is fixedly connected to the bottom of each of the three upper mounting blocks 111. A block 341 is fixedly connected to the bottom of each sliding column 34. A sleeve 2 35 is fixedly connected to the top of each of the three lower mounting blocks 111. The outer surface of the block 341 slides and limits the movement of the inner wall of the sleeve 2 35. The sleeve 2 35 slides and limits the movement of the outer surface of the sliding column 34. A spring 351 is fixedly connected to the bottom of the block 341. One end of the bottom of the spring 351 is fixedly connected to the top of the lower mounting block 111. When the frame is subjected to bumps, the resulting... The pressure is transmitted to tripod 1, causing it to move downwards. Since the two sleeves 32 are connected to the wheel and in contact with the ground, they cannot move downwards. Therefore, tripod 1 compresses damper 33, which in turn drives the three sliding columns 34 to press down, squeezing the corresponding spring 351, causing it to contract and absorb energy, thus achieving initial shock absorption. Subsequently, the unabsorbed downward pressure is transmitted to tripod 12, causing it to move downwards and squeezing the two dampers 31, causing them to contract. The contraction of dampers 31 also squeezes spring 321. At the same time, when dampers 31 move downwards, they work together with sleeves 32 to squeeze spring 311. This structure can effectively absorb the downward pressure on the frame caused by bumps through multiple shock absorption measures, achieving a good shock absorption effect.

[0029] A specific application of this embodiment is as follows: When the tire installed between the two sleeves 32 travels on bumpy or potholed roads, the frame will generate a downward impact force, which is transmitted to the tripod 1 through the column 11. At this time, the damper 33 will retract downward, and the mounting blocks 111 of the triangle of the tripod 1 will drive the sliding column 34 connected to it to move downward. The blocks 341 will compress the springs 351. Through the contraction of the damper 33 and the contraction of the three springs 351, the impact force generated by the frame is absorbed for the first time, achieving initial shock absorption. The unabsorbed impact force will act on the tripod 2 12, causing it to move downwards. Since the two sleeves 1 32 are connected to the tire and in contact with the ground, they cannot move downwards. Therefore, the two mounting blocks 111 on the tripod 2 12 will press down on the damper 1 31 connected to it, causing it to contract. At the same time, the damper 1 31 will also compress the spring 2 321 while it is pressing down. At the same time, when the damper 1 31 moves downwards, the lower block 23 at its top and the sleeve 1 32 work together to compress the spring 1 311. Through the above multiple measures, the effect of shock absorption is achieved again.

[0030] When replacing damper 31, first unscrew several bolts on the two mounting rings 24, then remove the two mounting rings 24. Next, rotate damper 31 counterclockwise. The lower circular block 23 and locking block 232 will rotate accordingly until the locking block 232 rotates 90 degrees and is blocked by the inner wall of the slot 22. Then, lower damper 31 to disengage the locking block 232 from the slot 22. Then, insert the locking block 232 from the new damper 31 into the slot 22. When the top of the lower circular block 23 contacts the bottom of the upper circular block 21, rotate damper 31 clockwise 90 degrees. At this point, it will lock. Both ends of block 232 will enter the two anti-rotation grooves 221 respectively. At this time, damper 31 cannot move down. Then, the two protrusions 242 of the inner rings of the two mounting rings 24 are inserted into the four locking grooves 212 on the outer surface of the upper round block 21 and the lower round block 23 respectively. At this time, the arc edges 241 at the top of the inner rings of the two mounting rings 24 will be inserted into the annular grooves 211, and the top of the arc edges 241 at the bottom of the inner wall of the two mounting rings 24 will contact the bottom of the lower round block 23. Finally, the two mounting rings 24 are fixed with several bolts to complete the installation. The other damper 31 is operated in the same way.
