Description

Technical Field

[0001] The present invention relates to the technical field of shock absorber detection, and in particular to a new energy vehicle shock absorber performance detection device. Background Art

[0002] Against the backdrop of global advocacy for energy conservation, emission reduction and sustainable development, the new energy vehicle industry is booming, and its ownership continues to rise, becoming a new trend in the development of the automotive industry. Due to the significant differences in the power system between new energy vehicles and traditional fuel vehicles, the body weight distribution and driving characteristics are also different, which puts more stringent requirements on the performance of shock absorbers. As a key component to ensure vehicle driving stability, comfort and handling safety, the performance of shock absorbers is directly related to the driving experience and driving safety. As consumers' requirements for the quality of new energy vehicles are increasing, accurate testing of shock absorber performance to ensure its stable and reliable operation under various working conditions has become an indispensable part of the research and development, production and quality control of new energy vehicles.

[0003] At present, the performance testing of shock absorbers for new energy vehicles covers multiple dimensions of testing items, including shock absorber appearance, static performance, and dynamic performance. However, in actual operation, these testing items can usually only be carried out one by one. When a comprehensive test is required, they have to be operated separately with the help of multiple devices. This undoubtedly leads to a significant extension of the time required for the entire testing process, which not only reduces the testing efficiency, but also increases labor costs and equipment losses to a certain extent. For example, after inspecting the appearance, the equipment parameters and installation methods need to be readjusted before static performance testing can be carried out, and then the equipment status needs to be changed again to carry out dynamic performance testing. Each conversion takes a lot of time.

[0044] During the test, first insert the lower end of the shock absorber into the lower clamping seat 3 to fix it and ensure that it is vertical. The shock absorber performance test body 1 pushes the horizontal electric push rod 21 to move the performance test structure 2 downward, so that the lower liquid ring 23 is sleeved on the upper end of the shock absorber. The safety liquid circulation device is started, and the liquid enters the input liquid channel 231, pushing the piston spring push rod 232 to fix the anti-slip gasket 233 to fix the upper end of the shock absorber. At the same time, the connecting pipe 234 is connected to the input liquid channel 231, and the liquid enters the output liquid channel 236 through it, and then flows into the lifting liquid pipe 22, pushing The lifting piston spring sleeve rod 221 moves downward, so that the lifting liquid pipe 22 is connected with the first variable diameter liquid pipe group 222, and the liquid flows into the lower liquid guide pipe 223 and the horizontal liquid pipe 24 in turn, pushing the pushing piston spring sleeve rod 241 to apply force to the shock absorber body.

This design not only realizes the synchronous detection of the static and dynamic performance of the shock absorber, but also reduces the dependence on multiple detection equipment, reducing labor costs and equipment losses.

[0046] As an embodiment of the present invention, Figure 3 、 Figure 4 、 Figure 5 、 Figure 7As shown, the liquid outlet end of the transverse liquid guide tube 243 is fixed to the outer ring 25 and communicates with the notch chute 251 opened inside the outer ring 25. The notch chute 251 is a nearly 360-degree upper open slot, and the slot body is downwardly penetrated with a liquid outlet 252 near the end, and an output interface is installed at the lower end of the liquid outlet 252. The internal sliding seal of the notch chute 251 is provided with a spring piston 253. The spring piston 253 consists of a piston and a spring fixed to the end of the piston. One end of the spring is fixed to the end wall of the notched slide groove 251, the upper side of the piston of the upper liquid ring 235 is fixed to the swivel 254 through a support rod, and the swivel 254 rotation seal is set on the upper side of the outer ring 25, and a detection camera 255 is fixedly set on the surface of the swivel 254 at the position of the piston of the upper liquid ring 235. The input interface of the lower liquid ring 23 is connected to the output end of the safety liquid circulation equipment through a pipeline, and the input end of the safety liquid circulation equipment is connected to the output interface below the liquid outlet 252 through a pipeline.

[0047] During operation, due to the similar structures of the horizontal and vertical components, the liquid enters the notched groove 251 of the outer ring 25, pushes the spring piston 253, drives the rotating ring 254 and the detection camera 255 to rotate and shoot, and the data is transmitted to the shock absorber performance detection body 1 for analysis, and the liquid finally flows back to the circulation equipment.

[0048] To sum up, by setting up the structure of the detection camera 255 and the swivel 254, when the safety liquid pushes the spring piston 253 to move, the swivel 254 and the detection camera 255 are driven to rotate to shoot the appearance and working status of the shock absorber, obtain real-time image data and transmit it to the shock absorber performance detection body 1 for analysis. This design realizes the simultaneous detection of the shock absorber appearance and other performance tests, further improves the comprehensiveness and accuracy of the detection, and helps to more comprehensively evaluate the shock absorber performance.

[0049] Working principle: When working, first adjust the horizontal electric push rod 21 and the lower clamping seat 3 through the control end of the shock absorber performance detection body 1 according to the size of the shock absorber to be detected, so that the shock absorber can be placed between the performance detection structure 2 and the lower clamping seat 3 without hindering the normal operation of the performance detection structure 2 and the lower clamping seat 3. After adjustment, insert the lower end of the shock absorber to be detected into the interior of the lower clamping seat 3, so that the lower clamping seat 3 clamps and fixes the lower end of the shock absorber, and ensures that the lower clamping seat 3 is in a vertical state, and then the shock absorber performance detection body 1 will push the horizontal electric push rod 21, so that it drives the performance detection structure 2 to move downward until the lower liquid ring 23 is installed on the upper end of the shock absorber, and then the safety liquid circulation equipment is started to transport the safety liquid into the transmission The safety liquid flows into the liquid channel 231, enters the space where the piston spring push rod 232 is located through the through hole on the annular path, pushes the piston spring push rod 232 outward, and makes the anti-slip gasket 233 fit tightly against the upper end of the shock absorber, thereby achieving stable fixation of the upper end of the shock absorber. At the same time, the piston end of the piston spring push rod 232 will move past the lower end of the connecting pipe 234, so that the connecting pipe 234 is connected with the input liquid channel 231, and then the safety liquid will enter the output liquid channel 236 through the connecting pipe 234, and enter the interior of the lifting liquid pipe 22 through the pipeline of the output liquid channel 236. With the influx of the safety liquid, the hydraulic force increases, and the safety liquid will push the lifting piston spring sleeve rod 221, and the compression spring moves downward. As the lifting piston spring sleeve rod 221 moves downward, the interior of the lifting liquid pipe 22 will be connected to the first reducing liquid pipe group 222, and then the safety liquid will pass through the first reducing liquid pipe group 222 into the interior of the lower liquid guide pipe 223, and then flow into the transverse liquid pipe 24 through the pipeline. In the transverse liquid pipe 24, the safety liquid pushes the push piston spring sleeve rod 241 to move toward the shock absorber body, and the detachable end of the output end of the push piston spring sleeve rod 241 contacts the shock absorber body and applies thrust. Due to the structural arrangement of the transverse liquid pipe 24, the push piston spring sleeve rod 241, the second reducing liquid pipe group 242 and the transverse liquid guide pipe 243 and the structural arrangement of the lifting liquid pipe 22, the lifting piston spring sleeve rod 221, the first reducing liquid pipe group 222 and the lower liquid guide pipe 223 The safety liquid flows and acts in these components in a similar manner. Therefore, the safety liquid enters the notched groove 251 of the outer ring 25 through the transverse liquid guide tube 243. In the notched groove 251, the safety liquid pushes the spring piston 253 to move along the inside of the notched groove 251. The compressed and moving spring piston 253 drives the rotating ring 254 and the detection camera 255 to rotate and move synchronously. The detection camera 255 will capture the real-time appearance and working status of the shock absorber in the current state, obtain relevant image data, and transmit the data to the shock absorber performance detection body 1 for processing and analysis. Finally, the safety liquid flows out through the liquid outlet 252 and returns to the input end of the safety liquid circulation device through the pipeline, thereby realizing the recycling of the safety liquid.

[0050] During the above process, technicians can control the pumping volume and efficiency of the safety liquid circulation equipment according to a pre-set program, allowing the pumping volume and efficiency to continuously increase or fluctuate. During the process of changing the pumping volume and efficiency, as the safety liquid continues to flow and the pressure changes, the lifting piston spring sleeve rod 221 in the lifting liquid pipe 22 will continue to move downward or reciprocate up and down under the action of the pressure of the safety liquid and the elastic force of the spring, driving the lower liquid ring 23 and the shock absorber connected thereto to undergo continuous pressure testing or vertical vibration simulation. At the same time, in the horizontal liquid pipe 24, the push piston spring sleeve rod 241 will continuously push the side of the shock absorber to perform lateral pressure testing on the shock absorber, or the push piston spring sleeve rod 241 will reciprocate to push the push shock absorber to simulate horizontal vibration. In this way, the stress conditions of the shock absorber in different directions can be simulated simultaneously. Through this complete workflow, simultaneous testing of multiple dimensions such as the appearance, static performance, and dynamic performance of the shock absorber of new energy vehicles is achieved, greatly improving testing efficiency and reducing labor costs and equipment loss.

[0051] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
