Abstract
Description
Technical Field
[0001] This application relates to the field of electric vehicle equipment, and in particular to an electric vehicle shock absorber. Background Technology
[0002] Electric vehicles, also known as electric-driven vehicles, are divided into AC electric vehicles and DC electric vehicles. Generally speaking, an electric vehicle uses a battery as its energy source, converting electrical energy into mechanical energy for movement through components such as a controller and motor. Speed is adjusted by controlling the magnitude of the current. Electric vehicles are equipped with shock absorbers, which are used to suppress the oscillations caused by the spring absorbing shocks and the impact from the road surface.
[0003] Shock absorbers are used to reduce vibrations during electric vehicle operation, making the ride more comfortable and safer for riders. Common shock absorbers use shock-absorbing springs to reduce vibrations. After prolonged use or when encountering very bumpy roads, the retaining ring block that fixes the shock-absorbing spring inside the shock absorber may be damaged, the shock-absorbing spring may lack limit, or the shock-absorbing spring may slip too much suddenly, affecting the rider's safety. Utility Model Content
[0004] In order to make electric vehicle shock absorbers safer and improve rider safety, this application provides an electric vehicle shock absorber.
[0005] This application provides a shock absorber for an electric vehicle, which adopts the following technical solution:
[0006] An electric vehicle shock absorber includes a shock absorber body, which comprises a housing and a shock absorber spring. The housing includes a connecting shell and a sliding cylinder slidably connected within the connecting shell. The shock absorber spring is disposed within the sliding cylinder, and the spring force direction is the same as the sliding direction of the sliding cylinder. A fixing rod is disposed within the connecting shell, with one end of the fixing rod located within the sliding cylinder. A fixing ring block is disposed at the end of the fixing rod near the shock absorber spring, and one end of the shock absorber spring is disposed on the fixing ring block. A connecting block is disposed at the end of the shock absorber spring away from the fixing ring block, and the radius of the connecting block is adapted to the radius of the sliding cylinder. The connecting block is disposed at the opening of the sliding cylinder away from the connecting shell and is connected to the electric vehicle body. A limiting ring block is disposed on the inner wall of the connecting shell near the bottom, through which the fixing rod passes. The outer diameter of the limiting ring block is larger than the radius of the shock absorber spring.
[0007] By adopting the above technical solution, the shock-absorbing spring is set inside the sliding cylinder, and a fixed rod is set inside the connecting shell. One end of the shock-absorbing spring is set on the fixed ring block. When the electric vehicle shock absorber is working, the sliding of the connecting shell drives the sliding of the fixed ring block, which compresses the shock-absorbing spring and the shock absorber plays its role in reducing the vibration of the electric vehicle. When the fixed ring block is damaged due to prolonged use or excessive bumps, the limiting ring block acts to resist the shock-absorbing spring, preventing the electric vehicle shock absorber from slipping too much. This reduces the risk of rider injury due to shock absorber failure, making the electric vehicle shock absorber safer and improving the rider's riding safety.
[0008] Optionally, the fixing rod is a hollow structure, and a sliding rod is slidably disposed inside the fixing rod. The sliding rod slides along the length direction of the fixing rod, and the shock-absorbing spring is sleeved on the sliding rod. The end of the sliding rod away from the fixing rod is disposed on the connecting block.
[0009] By adopting the above technical solution, the shock-absorbing spring is sleeved on the sliding rod, and the sliding rod prevents the shock-absorbing spring from deforming and makes the sliding of the fixed rod more stable.
[0010] Optionally, the sliding rod includes a sliding part and a connecting part, wherein the sliding part is slidably connected to the fixed rod, and the radius of the connecting part is larger than the radius of the sliding part.
[0011] By adopting the above technical solution, the radius of the connecting part is larger than the radius of the sliding part. When encountering very bumpy road sections, the connecting part can limit the excessive sliding of the connecting shell and prevent damage to the shock-absorbing spring.
[0012] Optionally, the circumferential sidewall of the fixing rod is provided with a locking block, the locking block is located inside the sliding cylinder, the outer diameter of the locking block matches the outer diameter of the fixing ring block, and the sliding cylinder is provided with an anti-detachment block circumferentially along the edge of the connecting shell. When the connecting shell slides toward the connecting block, the anti-detachment block abuts against the surface of the limiting ring block.
[0013] By adopting the above technical solution, the anti-detachment block prevents the locking block from detaching from the sliding cylinder. The anti-detachment block abuts against the surface of the limiting ring block, which plays a limiting role and prevents the shock-absorbing spring from having excessive elasticity. If the fixing ring block is damaged, the locking block plays a role in abutting against the shock-absorbing spring.
[0014] Optionally, a first buffer spring is sleeved on the fixing rod, with one end of the first buffer spring disposed on the locking block and the other end disposed on the side of the fixing ring block away from the shock-absorbing spring.
[0015] By adopting the above technical solution, when the anti-detachment block abuts against the limiting ring block, the first buffer spring plays a shock-absorbing and buffering role.
[0016] Optionally, a second buffer spring is provided at the bottom of the connecting shell, and the radius of the first buffer spring is the same as that of the second buffer spring.
[0017] By adopting the above technical solution, when the second buffer spring prevents the limiting ring block from being damaged, the sliding cylinder directly abuts against the bottom of the connecting shell, playing a shock absorption and buffering role, and improving the safety of the electric vehicle shock absorber.
[0018] Optionally, a waterproof gasket may also be included, wherein the fixing ring block has an annular groove for receiving the waterproof gasket.
[0019] By adopting the above technical solution, the waterproof gasket prevents water from entering the shock absorber.
[0020] Optionally, a fixing hole is provided at the bottom of the connecting shell.
[0021] By adopting the above technical solution, the shock absorber is connected to the electric vehicle tire frame through the fixing hole.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. When the electric vehicle shock absorber is working, the fixed ring block slides and causes the shock absorber spring to compress. When the fixed ring block is damaged, the limit ring block abuts against the shock absorber spring, making it less likely for the rider to be injured due to shock absorber failure. The electric vehicle shock absorber is safer, and the rider's riding safety is improved.
[0024] 2. The connecting part restricts excessive slippage of the connecting shell to avoid damage to the shock-absorbing spring;
[0025] 3. The second buffer spring prevents the sliding cylinder from directly contacting the bottom of the connecting shell in case the limit ring is damaged, thus improving rider safety. Attached Figure Description

[0031] This application discloses an electric vehicle shock absorber. (Refer to...) Figure 1 , Figure 2 An electric vehicle shock absorber includes a shock absorber body 1, which comprises a housing body 11 and a shock absorber spring 12. The housing body 11 includes a connecting shell 111 and a sliding cylinder 112 slidably connected within the connecting shell 111. The shock absorber spring 12 is fixed within the sliding cylinder 112, and the direction of the spring force of the shock absorber spring 12 is the same as the sliding direction of the sliding cylinder 112. A fixing hole 9 is provided at the bottom of the connecting shell 111, and a fixing rod 21 is fixed within the connecting shell 111. One end of the fixing rod 21 is located within the sliding cylinder 112, and a fixing ring block 22 is fixed to the end of the fixing rod 21 near the shock absorber spring 12. One end of the shock absorber spring 12 is fixed to the fixing ring block 22, and a connecting block 23 is fixed to the end of the shock absorber spring 12 away from the fixing ring block 22.
[0032] Reference Figure 1 , Figure 2 The radius of the connecting block 23 is adapted to the radius of the sliding cylinder 112. The connecting block 23 is fixed to the opening of the sliding cylinder 112 away from the connecting shell 111, and the connecting block 23 is connected to the electric vehicle body. An electric vehicle shock absorber also includes a waterproof washer 7, and an annular groove 8 is provided on the connecting block 23 for the waterproof washer 7 to be received.
[0033] Reference Figure 1 , Figure 2 , Figure 3 A limiting ring block 24 is fixed on the inner wall of the connecting shell 111 near the bottom. A fixing rod 21 passes through the limiting ring block 24, and the outer diameter of the limiting ring block 24 is larger than the radius of the shock-absorbing spring 12. The fixing rod 21 has a hollow structure, and a sliding rod 3 is slidably connected inside the fixing rod 21, sliding along the length of the fixing rod 21. The shock-absorbing spring 12 is sleeved on the sliding rod 3, and the end of the sliding rod 3 away from the fixing rod 21 is fixed to the connecting block 23. The sliding rod 3 includes a sliding part 31 and a connecting part 32. The sliding part 31 is slidably connected inside the fixing rod 21, and the radius of the connecting part 32 is larger than the radius of the sliding part 31.
[0034] Reference Figure 1 , Figure 2 , Figure 3 A locking block 41 is fixed to the circumferential side wall of the fixing rod 21. The locking block 41 is located inside the sliding cylinder 112, and its outer diameter matches that of the fixing ring block 22. An anti-detachment block 42 is fixed circumferentially to the edge of the sliding cylinder 112 near the connecting shell 111. When the connecting shell 111 slides closer to the connecting block 23, the anti-detachment block 42 abuts against the surface of the limiting ring block 24. A first buffer spring 5 is sleeved on the fixing rod 21. One end of the first buffer spring 5 is fixed to the locking block 41, and the other end is fixed to the side of the fixing ring block 22 away from the shock-absorbing spring 12.

[0035] The implementation principle of an electric vehicle shock absorber according to an embodiment of this application is as follows: The shock absorber is installed on the electric vehicle, and the shock-absorbing spring 12 is set inside the sliding cylinder 112. When the electric vehicle encounters a bumpy road, the electric vehicle shock absorber works. The connecting shell 111 slides, causing the fixed ring block 22 to slide, which compresses the shock-absorbing spring 12 and realizes the shock absorption of the electric vehicle. The connecting part 32 prevents the connecting shell 111 from sliding too much when bumpy. The locking block 41 prevents the fixed ring block 22 from being damaged. The anti-detachment block 42 abuts against the limiting ring block 24. The first buffer spring 5 plays a role in shock absorption and buffering. The second buffer spring 6 prevents the sliding cylinder 112 from directly abutting the bottom of the connecting shell 111 when the limiting ring block 24 is damaged. The shock absorber is equipped with multiple safety measures to prevent the spring from directly contacting the bottom of the connecting shell 111 when the internal components of the shock absorber are damaged. This makes it less likely for the rider to be injured due to the damage of the shock absorber. The electric vehicle shock absorber is safer, and the rider's riding safety is improved.
[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
