A telescopic cylinder is fixedly installed in the middle of the lower end of the oil supply tank. An oil supply nozzle is arranged at the lower end of the telescopic cylinder. A supply oil pipe is arranged on the outer surface of the right part of the oil supply nozzle. The upper end of the supply oil pipe is fixedly connected to the lower part of the right end of the oil supply tank.

[0004] In the existing oil injection device for shock absorbers of new energy vehicles such as the above, while the first motor is used to push the vertical plate to achieve the horizontal positioning of the shock absorber, the second motor is used to push the movable rod to achieve the compression of the shock absorber. In the specific implementation process, the first motor drives the translation of the vertical seat through a lead screw. The translation speed of the lead screw is relatively low, and when injecting oil into shock absorbers of the same model, the vertical plate needs to be translated by a specified span each time, resulting in a reduction in the oil injection speed of the shock absorber. Therefore, it is urgent to propose a corresponding oil injection device for shock absorbers of new energy vehicles to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to propose an oil injection device for shock absorbers of new energy vehicles to solve the above problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] An oil injection device for shock absorbers of new energy vehicles includes a housing, an oil delivery assembly, a workbench and a positioning assembly. The positioning assembly includes a fixed seat, a positioning block and a vertical pushing part for compressing the shock absorber. The fixed seat is fixedly connected to the top of the workbench. A placement groove is opened at the top of the workbench. A cross bar is fixedly connected to the outer surface of the positioning block. The outer surface of the cross bar is slidably connected to the inner surface of the vertical end of the fixed seat. A spring is fixedly connected between the fixed seat and the positioning block. And a locking assembly for locking the position of the cross bar is arranged on the outer surface of the fixed seat.

[0008] Preferably, a locking rod is inserted through the horizontal end of the fixed seat, and the locking rod is fixedly connected to the top of the workbench through a screw hole.

[0009] Preferably, multiple groups of the screw holes are provided, and the multiple groups of screw holes are horizontally linearly distributed.

[0012] Preferably, the locking assembly includes a positioning rod. The outer wall of the positioning rod is screwed to the outer wall of the fixed seat. The cross-section of the cross bar has a rectangular structure, and the open end of the positioning rod abuts against the outer wall of the cross bar.

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] 1. In this application, the piston sleeve side of the shock absorber is inserted between two groups of positioning blocks until the bottom of the piston sleeve abuts against the placement groove. After the two groups of positioning blocks move relatively and compress the corresponding springs, the two groups of positioning rods are respectively rotated so that their open ends respectively abut against the outer walls of the two groups of cross bars. At this time, the positions of the two groups of positioning blocks are locked, and the two groups of springs are in a constant compression state. The two groups of positioning blocks abut against the outer wall of the piston sleeve to realize the horizontal positioning of the shock absorber. Then, the pushing member pushes the push plate to compress the shock absorber. The operator places it on the top of the oil storage cylinder body, and completes the oil injection operation through the oil feeding assembly. Subsequently, keeping the positions of the two groups of positioning blocks unchanged, the shock absorber that has completed the oil injection can be taken out upward. Similarly, subsequent shock absorbers of the same batch can also be positioned by placing them vertically between the two groups of positioning blocks, without the need to adjust the positions of the positioning blocks every time. By improving the convenience of disassembling and fixing the shock absorber, the convenience of using the oil injection device for the shock absorber of new energy vehicles is improved.

[0015] 2. In this application, the screw passes through the fixed seat in the positioning assembly and is fixed to the workbench through the screw holes at the corresponding positions, thereby ensuring the convenience of disassembling and assembling the positioning assembly. Moreover, the fixed seat can be corresponded to the screw holes at different positions, so that within the constant spring expansion and contraction range, the size of the shock absorber that the positioning assembly can adapt to is further expanded.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0024] A refueling device for a shock absorber of a new energy vehicle, including a housing 1, an oil delivery component 2, a workbench 7 and a positioning component. The positioning component includes a fixed seat 4, a positioning block 6 and a vertical pushing part for compressing the shock absorber. The fixed seat 4 is fixedly connected to the top of the workbench 7. A placing groove 3 is opened at the top of the workbench 7. The outer wall of the positioning block 6 is fixedly connected with a cross bar 5. The outer wall of the cross bar 5 is slidably connected to the inner wall of the vertical end of the fixed seat 4. A spring 10 is fixedly connected between the fixed seat 4 and the positioning block 6, and a locking component for locking the position of the cross bar 5 is arranged on the outer wall of the fixed seat 4;

[0025] Insert the piston sleeve side of the shock absorber between two groups of positioning blocks 6 until the bottom of the piston sleeve abuts against the placement groove 3. After the two groups of positioning blocks 6 move relatively and compress the corresponding springs 10, rotate the two groups of positioning rods 11 respectively so that their open ends abut against the outer walls of the two groups of cross bars 5. At this time, the positions of the two groups of positioning blocks 6 are locked, the two groups of springs 10 are in a constant compressed state, and the two groups of positioning blocks 6 both abut against the outer wall of the piston sleeve to achieve the horizontal positioning of the shock absorber. Then, the pusher 12 pushes the push plate 13 to compress the shock absorber. The operator opens the top of the oil storage cylinder body and completes the oil injection operation through the oil delivery assembly 2. Subsequently, keeping the positions of the two groups of positioning blocks 6 unchanged, the shock absorber that has completed the oil injection can be taken out upward. Similarly, for subsequent shock absorbers of the same batch, they can also be positioned by placing them vertically between the two groups of positioning blocks 6, without the need to adjust the positions of the positioning blocks 6 each time. By improving the convenience of disassembling and positioning the shock absorber, the convenience of using the oil injection equipment for new energy vehicle shock absorbers is improved.

[0026] Specifically, as Figure 2 shown in Figure 4 the figure, a locking rod 9 is inserted through the horizontal end of the fixed seat 4. The locking rod 9 is fixedly connected to the top of the workbench 7 through the screw holes 8. There are multiple groups of screw holes 8, and the multiple groups of screw holes 8 are horizontally linearly distributed. The locking rod 9 passes through the fixed seat 4 in the positioning assembly and is fixed to the workbench 7 through the screw holes 8 at the corresponding positions, thus ensuring the convenience of disassembling and assembling the positioning assembly. Moreover, the fixed seat 4 can be corresponded to the screw holes 8 at different positions, so that within the constant telescopic range of the spring 10, the size range of the shock absorber that the positioning assembly can adapt to is further expanded.

[0027] Specifically, as Figure 2 shown in Figure 3 the figure, the vertical pushing part includes a vertical plate 15 fixedly connected to the top of the positioning block 6. The vertical plate 15 is of an L-shaped structure. A pusher 12 is fixedly connected to the top of the vertical plate 15, and the output end of the pusher 12 is fixedly connected to a push plate 13. The push plate 13 is arranged to fit the outer contour of the shock absorber. The pusher 12 pushes the push plate 13 to compress the shock absorber. The outer wall of the push plate 13 is slidably connected to the inner wall of the vertical plate 15 through a vertical groove 14, thus ensuring the stability of the vertical movement of the push plate 13. The locking assembly includes a positioning rod 11. The outer wall of the positioning rod 11 is screwed with the outer wall of the fixed seat 4. The cross section of the cross bar 5 is of a rectangular structure, and the open end of the positioning rod 11 abuts against the outer wall of the cross bar 5. The positioning rod 11 is screwed with the fixed seat 4 until the open end of the positioning rod 11 abuts against the outer wall of the cross bar 5. At this time, the frictional force generated between the positioning rod 11 and the cross bar 5 can limit the position of the cross bar 5.

[0028] Working principle: Insert the piston sleeve side of the shock absorber between two groups of positioning blocks 6 until the bottom of the piston sleeve abuts against the placement groove 3. After the two groups of positioning blocks 6 move relatively and compress the corresponding springs 10, rotate the two groups of positioning rods 11 respectively so that their open ends abut against the outer walls of the two groups of cross bars 5. At this time, the positions of the two groups of positioning blocks 6 are locked, the two groups of springs 10 are in a constant compression state, and the two groups of positioning blocks 6 both abut against the outer wall of the piston sleeve to achieve the horizontal positioning of the shock absorber. Then, the pusher 12 pushes the push plate 13 to compress the shock absorber. The operator opens the top of the oil storage cylinder body and completes the oil injection operation through the oil delivery assembly 2. Subsequently, keeping the positions of the two groups of positioning blocks 6 unchanged, the shock absorber that has completed the oil injection can be taken out upward. Similarly, subsequent shock absorbers of the same batch can also be positioned by placing their vertical ends between the two groups of positioning blocks 6, without the need to adjust the positions of the positioning blocks 6 each time. By improving the convenience of disassembling and positioning the shock absorber, the convenience of using the oil injection equipment for new energy vehicle shock absorbers is improved. The locking rod 9 passes through the fixed seat 4 in the positioning assembly and is fixed to the workbench 7 through the screw holes 8 at the corresponding positions, thereby ensuring the convenience of disassembling and assembling the positioning assembly. Moreover, the fixed seat 4 can correspond to the screw holes 8 at different positions, so that within the constant telescopic range of the spring 10, the size range of the shock absorber that the positioning assembly can adapt to is further expanded.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.
