Description

Technical Field

[0001] This invention relates to the field of front wheel shock absorption technology for freight tricycles, specifically to the rocker arm triangle front shock absorption of electric freight tricycles. Background Technology

[0002] Traditional electric freight tricycles still rely on mechanical external springs and hydraulic devices to achieve the front wheel's shock absorption effect through simple axial extension and retraction. The structure and style are simple, and the shock absorption effect is not good when riding on bumpy roads.

[0003] However, existing shock absorbers are unable to suppress the rapid rebound of springs through the synergistic effect of damping components and rigid structures during use. This results in secondary vibrations after the vehicle passes over bumpy roads, which not only reduces driving comfort but also causes the cargo in the cargo box to shift or be damaged due to continuous bumps. Summary of the Invention

[0004] The purpose of this invention is to provide a front shock absorber for the rocker arm triangle of a freight electric tricycle. By setting up a shock absorber, the problem of existing shock absorbers being unable to suppress the rapid rebound of springs through the synergistic effect of damping components and rigid structures during use is solved. This results in secondary vibrations after the vehicle passes over bumpy roads, which not only reduces driving comfort but also causes the cargo in the cargo box to shift or be damaged due to continuous bumps.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a front shock absorber for a rocker arm triangle of an electric freight tricycle. The tricycle is included, along with: a shock absorber mounted on the tricycle; several disassembly parts, each disposed on the shock absorber; a buffer assembly mounted on the tricycle; and a connecting assembly disposed on the buffer assembly. The buffer assembly includes two connecting rods located on the front side of the tricycle, each connecting rod having a hinge plate fixedly connected to its outer wall; a hinge block on the front side of each hinge plate; and a connecting block at the bottom of each connecting rod. Two hinge blocks are fixedly connected. Two hinge blocks are provided at the bottom of two hinge blocks. Two hinge blocks are fixedly connected to the top of the connecting rods. Two hinge blocks are provided at the top of each of the two hinge blocks. Two dampers are fixedly connected between the two hinge blocks and the two hinge blocks. Two elastic elements are provided on the two dampers. The output end of the damper is fixedly connected to the hinge block. The elastic element includes a spring sleeved on the outer wall of the damper. The bottom of the spring is fixedly connected to the damper. The bottom of the spring is fixedly connected to the hinge block. The spring is in a compressed state after installation.

[0006] Furthermore, the disassembly part includes a limiting component mounted on the shock-absorbing part; a reset component disposed on the limiting component; and the disassembly part is disposed at the hinge point on the shock-absorbing part.

[0007] Furthermore, the connecting assembly includes two connecting rods two fixedly connected to the outer wall of two connecting rods one, a frame handlebar fixedly connected between the two connecting rods two, the frame handlebar being rotatably connected to the tricycle, the top of the connecting assembly passing through the upper connecting rod two, a handlebar fixedly connected to the top of the frame handlebar, a rolling element provided on the connecting rod, the two connecting rods two being mirror images of each other, the rolling element including a connecting rod three rotatably connected to the connecting rod, a wheel fixedly connected to the outer wall of the connecting rod three, and an anti-slip strip provided on the outer wall of the wheel.

[0008] Furthermore, the limiting component includes a hollow rod passing through the hinge plate and the hinge block, with a plurality of limiting balls disposed inside the hollow rod, all of which extend outside the hollow rod. A limiting rod is disposed inside the hollow rod, and a limiting member is disposed on the hollow rod. The limiting balls are arranged in a circumferential array and are in contact with the hinge plate. The limiting member includes a limiting ring fixedly connected to the outer wall of the hollow rod and is in contact with the hinge plate.

[0009] Furthermore, the reset assembly includes a sliding ring slidably connected to the inner wall of the hollow rod, and a connecting rod four is fixedly connected to the inner wall of the limiting assembly. The right side of the connecting rod four extends to the outside of the hollow rod, and an elastic element two is provided on the connecting rod four. The left side of the connecting rod four is fixedly connected to the limiting rod. The elastic element two includes a spring two sleeved on the outer wall of the connecting rod four. The right side of the spring two is fixedly connected to the hollow rod, and the left side of the spring two is fixedly connected to the sliding ring. The spring two is in its natural state after installation.

[0010] The present invention has the following beneficial effects: 1. This invention, by setting up a shock-absorbing part, when the wheel encounters a road bump and moves upward, the connecting rod three pushes the front side of the connecting rod, causing the connecting rod to swing around the hinge block two as a fulcrum. When the front end of the connecting rod swings upward, it simultaneously pushes the hinge block three and the hinge block four. Under the limiting action of the hinge plate and the hinge block one, the damper is forced to contract and squeeze the spring one to contract synchronously. After the external force disappears, the spring one has a tendency to quickly return to its original position. At this time, the damping effect of the damper limits the rebound speed of the spring one, allowing it to return to its original position smoothly. At the same time, the connecting rod, the connecting rod one, and the damper form a triangular stable structure, which participates in the force transmission and attitude maintenance of the entire shock absorption process. Combining the stabilizing effect of the triangular mechanical structure and the decomposition effect of the rocker arm structure, it achieves a dual improvement in shock filtering effect and structural stability and reliability.

[0011] 2. This invention features a disassembly mechanism. During installation, first align the hinge block one with the pre-drilled hole in the hinge plate. Hold the hollow rod and press the connecting rod four, causing the sliding ring to stretch the spring two, simultaneously pulling the limiting rod to move. This allows the smaller diameter end of the limiting rod to slide to the limiting ball, releasing the radial restriction on the limiting ball. The limiting ball then retracts into the hollow rod, allowing the hollow rod to be smoothly inserted into the pre-drilled hole in the hinge plate and hinge block one. After insertion, release the connecting rod four, and the spring two returns to its original position, causing the limiting rod, sliding ring, and connecting rod four to return to their original positions. In position, the large-diameter end of the limiting rod pushes the limiting ball outward and locks it in place, completing the fixation of hinge block one, hinge block four, damper and spring one on connecting rod one and hinge block two; during disassembly, the operation of pressing connecting rod four is repeated to retract the limiting ball, and the hollow rod can be quickly pulled out to realize the component disassembly, replacing the traditional bolt and nut fastening method. No additional tools are needed, which greatly shortens the installation and disassembly time of core components such as hinge blocks, dampers, and springs, and improves assembly efficiency and convenience of later maintenance.

[0018] The disassembly unit 3 includes a limiting component 31, which is mounted on the shock-absorbing unit 2; and a reset component 32, which is disposed on the limiting component 31. The disassembly units 3 are respectively disposed at hinge points on the shock-absorbing unit 2. The limiting component 31 includes a hollow rod 311 that passes through the hinge plate 212 and the hinge block 213. A plurality of limiting balls 312 are disposed inside the hollow rod 311, and the plurality of limiting balls 312 extend outside the hollow rod 311.

The spring 323 is in a natural state after installation. By setting the disassembly part 3, the traditional bolt and nut fastening method is replaced. No additional tools are needed, which greatly shortens the installation and disassembly time of core components such as hinge blocks, dampers, and springs, and improves assembly efficiency and convenience of later maintenance.

[0019] In use, first install hinge block 1 213, hinge block 4 217, damper 218, and spring 1 219 onto connecting rod 1 211 and hinge block 2 214. During installation, place hinge block 1 213 on hinge plate 212, aligning the pre-drilled holes on hinge plate 212 and hinge block 1 213. Then insert hollow rod 311 into the pre-drilled holes on hinge plate 212 and hinge block 1 213. When inserting, first hold hollow rod 311. 1. Then, press the connecting rod 322 with your thumb. The connecting rod 322 will move along with the sliding ring 321. When the sliding ring 321 moves, it will stretch the spring 323. As the connecting rod 322 moves, the limiting rod 313 will also move. When the limiting rod 313 moves, the smaller diameter end will slide to the limiting ball 312. At this time, the limiting ball 312 will no longer be restricted by the limiting rod 313 and will slide into the hollow rod 311. Insert the hollow rod 311 into the limiting ball 312 and the limiting rod 313. After insertion, release the connecting rod 322. The spring 323 will then reset the limiting rod 313, the sliding ring 321, and the connecting rod 322. When the limiting rod 313 resets, it will push the limiting ball 312 out again. After the limiting ball 312 is pushed out, it will be limited, thus achieving the desired effect. The hinge block 213, hinge block 217, damper 218, and spring 219 are installed on the connecting rod 211 and hinge block 214 for quick installation. When removing them, the connecting rod 4 322 can be pressed to retract the limiting ball 312, thereby facilitating the disassembly and maintenance of the hinge block 213, hinge block 217, damper 218, and spring 219 installed on the connecting rod 211 and hinge block 214. After installing hinge block 1 213, hinge block 4 217, damper 218, and spring 1 219 onto connecting rod 1 211 and hinge block 2 214, the device is ready for use. During use, wheel 225 will contact the ground. During normal driving, wheel 225 will rotate on connecting rod 215, carrying connecting rod 3 224. When wheel 225 encounters a protrusion, it will be pushed upwards. As wheel 225 moves upwards, it will push the front of connecting rod 215 through connecting rod 3 224. After being pushed, connecting rod 215 will move on hinge block 2 214. When the front end of connecting rod 215 moves upwards... Pushing hinge block 3 216 and hinge block 4 217 upwards causes the damper 218 to contract due to the limiting effect of hinge plate 212 and hinge block 1 213. When the damper 218 contracts, spring 1 219 is compressed and then contracts. After being compressed, spring 1 219 quickly returns to its original position. At this time, the damper 218 limits the rapid return of spring 1 219 and allows it to return to its original position more slowly, thus preventing the amplified vibration caused by rapid return. The triangular structure formed by connecting rod 215, connecting rod 1 211, and damper 218 also provides a certain degree of stability for vibration reduction.
