Description

Technical Field

[0001] This utility model relates to the field of electric vehicle front forks, specifically to an oil injection device for electric vehicle front forks. Background Technology

[0002] The front fork is one of the most important components of an electric vehicle. Its main function is to connect the frame to the wheels, providing shock absorption and guidance. To ensure the proper functioning of the front fork and extend its lifespan, it is necessary to regularly inject lubricating oil into the fork.

[0003] Currently, when lubricating the front fork of an electric vehicle, the operator usually holds the oil can and aligns the oil nozzle with the gap between the fixing rod of the shock absorber and the dust cover of the front fork to inject oil. However, this method of lubrication is prone to oil leakage during the process, which not only wastes the oil but also pollutes the front fork and the surrounding environment, making it impractical.

[0004] Therefore, it is necessary to invent an oil injection device for electric vehicle front forks to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an oil injection device for electric vehicle front forks. By setting two oil injection semi-rings, oil can be evenly injected into the gap between the fixed tube and the dust cover. By setting guide plates, baffles, and insert-type lubricants, the injection can be evenly distributed. It is not easy to leak during oil injection, which can solve the problem that existing oil injection methods are prone to lubricant leakage during the oil injection process, which not only wastes lubricant but also pollutes the front fork and the surrounding environment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil injection device for an electric vehicle front fork, comprising... Oil filling bottles are used for storing and filling oil. Oil pipelines are used to transport lubricating oil; The oil injection assembly is used to inject lubricating oil into the gap between the fixed rod and the dust cover.

The lower part of the guide plate is fixedly connected to an insert plate. The bottom of the oil injection semi-ring is fixedly connected to a baffle plate. The guide plate is located on the outer side and the baffle plate is located on the inner side. The top of the oil injection semi-ring is fixedly connected to an oil inlet for communicating with an oil supply pipe. The lower part of the inner wall of the oil injection semi-ring has multiple oil outlets. The inner wall of the oil outlet is fixedly connected to a barrier plate.

[0007] Preferably, the front and rear parts of the oil injection semi-ring on the left side are fixedly connected with retaining strips.

[0008] Preferably, the front and rear parts of the oil injection semi-ring on the right side are fixedly connected with slots, and the locking strips are movably connected to each other.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figure 1 - Figure 3 The illustrated oiling device for an electric vehicle front fork includes an oil bottle 1, an oil supply pipe 2, and an oiling assembly 3. Oil bottle 1 is used for storing and filling oil. It can be made of plastic or rubber and can deform to facilitate the extrusion of oil. Oil pipe 2, used to transport lubricating oil, can be a flexible hose; like Figure 2 - Figure 4 As shown, the oil injection assembly 3 is used to inject lubricating oil into the gap between the fixed rod and the dust cover. The oil injection assembly 3 includes two oil injection semi-rings 31, which are symmetrically arranged and can form a ring. The inner diameter of the ring is adapted to the diameter of the fixed tube. Guide plates 32 are fixedly connected to the bottom of the two oil injection semi-rings 31, which are used to guide the oil and prevent oil leakage during injection. Insert plates 321 are fixedly connected to the lower part of the guide plates 32, and baffle plates 33 are fixedly connected to the bottom of the oil injection semi-rings 31. The wall is in contact with the outer wall of the fixed pipe. There is an oil storage gap between the lower part of the baffle 33 and the guide plate 32. The guide plate 32 is located on the outside and the baffle 33 is located on the inside. The top of the oil injection semi-ring 31 is fixedly connected to the oil inlet 311 for connecting with the oil supply pipe 2 and for allowing oil to enter the oil injection semi-ring 31. The lower part of the inner wall of the oil injection semi-ring 31 has multiple oil outlets 314. The inner wall of the oil outlet 314 is fixedly connected to the barrier plate 315, which can be made of silicone. It is used to block the oil. The oil can only flow out when the oil bottle 1 is squeezed.

[0018] The front and rear parts of the oil injection semi-ring 31 on the left are fixedly connected with a retaining strip 312, which has an isosceles trapezoidal cross section. The front and rear parts of the oil injection semi-ring 31 on the right are fixedly connected with a retaining groove 313. The retaining strip 312 is movably connected to the retaining strip 312 to cooperate in the splicing between the two oil injection semi-rings 31.

[0019] like Figure 1 - Figure 2 As shown, a refueling pipe 11 is fixedly connected to the top of the oil bottle 1 for allowing oil to enter the oil bottle 1. A pipe cap is installed on the upper part of the pipe. Two connecting pipes 12 are fixedly connected to the lower part of the oil bottle 1 for allowing oil to flow into the oil delivery pipe 2. A connecting sleeve 21 is fixedly connected to the upper end of the oil delivery pipe 2. The connecting sleeve 21 is threadedly connected to the connecting pipe 12 for connecting the oil delivery pipe 2 and the connecting pipe 12. A sealing ring 22, which can be made of rubber, is installed between the refueling pipe 11 and the connecting sleeve 21 to prevent oil leakage.

[0020] The working principle of this utility model is as follows: During oil filling, firstly, the two oil filling semi-rings 31 are respectively clamped to the outside of the fixed pipe, and the two oil filling semi-rings 31 are formed into a ring by the two clamping strips 312 and the clamping grooves 313. Then, the insert 321 at the bottom of the oil filling semi-ring 31 is inserted into the gap between the fixed rod and the dust cover. Then, lubricating oil can be poured into the oil filling bottle 1 through the filling pipe 11 at the top of the oil filling bottle 1. The lubricating oil will enter the oil delivery pipe 2 through the connecting pipe 12 at the bottom of the oil filling bottle 1, and then pass through the oil delivery pipe 2... The oil is fed into the oil filling semi-ring 31 through the oil inlet 311. When the oil enters the oil filling semi-ring 31, it will not flow out immediately because the oil outlet 314 is equipped with a baffle plate 315. Tighten the cap of the oil filling pipe 11 and then squeeze the oil bottle 1. Due to the pressure change, the baffle plate 315 will be opened, and the oil will flow out through the oil outlet 314. It will then flow into the gap between the fixed pipe and the dust cover through the guide plate 32 and the baffle plate 33, thereby lubricating the fixed rod and the moving rod.

[0021] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
