Description

Technical Field

[0001] The present invention relates to the technical field of shock absorber detection, and specifically provides a device for detecting the performance of a shock absorber of a new energy vehicle. Background Technique

[0002] Under the background of the global advocacy of energy conservation, emission reduction and sustainable development, the new energy vehicle industry has flourished, and its ownership has continued to climb, becoming a new trend in the development of the automotive industry. Since the power system of new energy vehicles is significantly different from that of 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 the driving stability, comfort and handling safety of vehicles, the performance of shock absorbers directly affects the driving experience and driving safety. With the increasing quality requirements of consumers for new energy vehicles, accurately detecting the performance of shock absorbers and ensuring their stable and reliable operation under various working conditions have become an indispensable important part in the research and development, production and quality control links of new energy vehicles.

[0003] Currently, in the performance detection link of new energy vehicle shock absorbers, there are multiple detection items covering the appearance, static performance and dynamic performance of shock absorbers. However, in the actual operation process, these detection items usually can only be carried out separately one by one. When comprehensive detection is required, multiple devices have to be used for separate operations, which undoubtedly leads to a significant extension of the time required for the entire detection process, not only reducing the detection efficiency, but also increasing the labor cost and equipment loss to a certain extent. For example, after detecting the appearance, the equipment parameters and installation methods need to be readjusted to perform static performance detection, and then the equipment state needs to be changed again to carry out dynamic performance detection, and each conversion takes a lot of time.

The output end of the horizontal electric push rod 21 is fixed to the lifting liquid pipe 22, and the output end of the horizontal electric push rod 21 is fixed below the side of the lifting liquid pipe 22. A middle-shaped pipe hole is provided inside the lifting liquid pipe 22, and an input interface is installed at the upper port. And a lifting piston spring sleeve rod 221 is slidably and sealingly arranged inside the lifting liquid pipe 22.

A first variable-diameter liquid pipe group 222 is fixedly communicated with the left side of the lifting liquid pipe 22. The first variable-diameter liquid pipe group 222 is composed of at least two pipe bodies and is fixedly arranged in a linear array from top to bottom on the left side of the lifting liquid pipe 22. And the inner diameter of the first variable-diameter liquid pipe group 222 gradually increases from top to bottom. One end of the first variable-diameter liquid pipe group 222 is fixedly communicated with the lower guide liquid pipe 223, and the lower end of the lower guide liquid pipe 223 is penetrated, and an input interface is assembled at the penetrated port. An input liquid channel 231 is provided inside the lower liquid ring 23 on the centrifugal side. And several through holes are penetrated from the annular path of the input liquid channel 231 towards the center of the lower liquid ring 23. And a piston spring push rod 232 is slidably and sealingly arranged inside the through holes. An input interface communicating with the inside of the input liquid channel 231 is provided on the side of the lower liquid ring 23. A ring plate is integrally arranged on the rod body of the piston spring push rod 232. And a spring is sleeved on the rod body of the piston spring push rod 232 on the centripetal side of the ring plate. And the two ends of the spring are respectively fixed to the ring plate and the inner wall of the through hole where the piston spring push rod 232 is located. One end of the piston spring push rod 232 passing through the connecting pipe 234 is movably connected to the anti-slip gasket 233. And the surface of the anti-slip gasket 233 in contact with the upper end of the shock absorber has anti-slip patterns. The lower liquid ring 23 is fixedly communicated with a connecting pipe 234 on the path of the through hole where the piston spring push rod 232 is located. And the upper end of the connecting pipe 234 is fixed to the upper liquid ring 235 and is communicated with an output liquid channel 236 provided inside the upper liquid ring 235 through the connecting pipe 234.

And the output interface is communicated with the interface at the upper end of the lifting liquid pipe 22 through a pipeline. The lower surface of the horizontal electric push rod 21 is fixed to the horizontal liquid pipe 24 through a support rod. An interface for inputting safety liquid is assembled at the left end of the horizontal liquid pipe 24. And the interface is communicated with the interface at the lower end of the lower guide liquid pipe 223 through a pipeline. And a top push piston spring sleeve rod 241 is slidably and sealingly arranged inside the horizontal liquid pipe 24. A second variable-diameter liquid pipe group 242 is fixedly arranged below the horizontal liquid pipe 24 and is fixedly communicated with the horizontal guide liquid pipe 243 through the second variable-diameter liquid pipe group 242. The structural settings of the horizontal liquid pipe 24, the top push piston spring sleeve rod 241, the second variable-diameter liquid pipe group 242 and the horizontal guide liquid pipe 243 are the same as those of the lifting liquid pipe 22, the lifting piston spring sleeve rod 221, the first variable-diameter liquid pipe group 222 and the lower guide liquid pipe 223. Among them,The output end of the pushing piston spring sleeve rod 241 is set as a detachable end, and the end can be selected according to the actual situation, and the output end of the pushing piston spring sleeve rod 241 points to the spring body of the shock absorber.

[0019] During the detection, first insert the lower end of the shock absorber into the lower clamping seat 3 and fix it to ensure its verticality. The shock absorber performance detection main body 1 pushes the horizontal electric push rod 21 to move the performance detection structure 2 downward, so that the lower liquid ring 23 is sleeved on the upper end of the shock absorber. The safe liquid circulation device is started, and the liquid enters the input liquid channel 231, pushes the piston spring push rod 232, so that the anti-slip gasket 233 fixes the upper end of the shock absorber. At the same time, the communication pipe 234 is communicated with the input liquid channel 231, and the liquid enters the output liquid channel 236 through this, and then flows into the lifting liquid pipe 22, pushing the lifting piston spring sleeve rod 221 downward, so that the lifting liquid pipe 22 is communicated 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 sequence, pushing the pushing piston spring sleeve rod 241 to apply force to the shock absorber body. Technicians can control the pumping volume and efficiency of the safe liquid circulation device, so that the lifting piston spring sleeve rod 221 and the pushing piston spring sleeve rod 241 move correspondingly, simulate the force conditions of the shock absorber in different directions, realize multi-dimensional synchronous detection, improve the detection efficiency, and reduce costs and losses.

[0020] In summary, by setting the cooperative working mechanism of the shock absorber performance detection main body 1, the performance detection structure 2 and the lower clamping seat 3, the multi-dimensional performance detection of the new energy vehicle shock absorber can be carried out quickly and accurately. The lower clamping seat 3 can firmly fix the lower end of the shock absorber, and the performance detection structure 2 can flexibly adjust the position and apply force from different directions, avoiding the cumbersome operations of repeatedly adjusting the equipment and installation methods in traditional detection, greatly shortening the detection time and improving the detection efficiency; by setting the input liquid channel 231, the piston spring push rod 232, the communication pipe 234, the output liquid channel 236 and the related liquid pipes and piston structures, the safe liquid circulates in the system, and the hydraulic force is used to push the lifting piston spring sleeve rod 221 and the pushing piston spring sleeve rod 241 to simulate the force conditions of the shock absorber in different directions. This design not only realizes the synchronous detection of the static and dynamic performance of the shock absorber, but also reduces the dependence on a variety of detection equipment, and reduces the labor cost and equipment loss.

[0021] As an embodiment of the present invention, such as Figure 3 、 Figure 4 、 Figure 5 、 Figure 7As shown in the figure, the liquid outlet end of the horizontal liquid guide pipe 243 is fixed to the outer sleeve ring 25 and communicates with the notch chute 251 opened inside the outer sleeve ring 25. The notch chute 251 is an upper open chute body of nearly 360 degrees, and a liquid outlet 252 is opened downwardly through the chute body near the end. And an output interface is installed at the lower port of the liquid outlet 252. A spring piston 253 is slidably and sealingly arranged inside the notch chute 251. The spring piston 253 is composed 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 notch chute 251. The upper side of the piston of the upper liquid ring 235 is fixed to the rotating ring 254 through a support rod. The rotating ring 254 is rotatably and sealingly arranged on the upper side of the outer sleeve ring 25. And a detection camera 255 is fixedly arranged on the surface of the rotating ring 254 at the position of the piston of the upper liquid ring 235. The input interface of the lower liquid ring 23 is communicated with the output end of the safety liquid circulation device through a pipeline. And the input end of the safety liquid circulation device is communicated with the output interface below the liquid outlet 252 through a pipeline.

[0022] During operation, since the horizontal and vertical components have similar structures, the liquid enters the notch chute 251 of the outer sleeve ring 25, pushes the spring piston 253, drives the rotating ring 254 and the detection camera 255 to rotate and take pictures, and the data is transmitted to the shock absorber performance detection main body 1 for analysis. Finally, the liquid flows back to the circulation device.

[0023] In summary, by setting the structure of the detection camera 255 and the rotating ring 254, when the safety liquid pushes the spring piston 253 to move, it drives the rotating ring 254 and the detection camera 255 to rotate and take pictures of the appearance and working state of the shock absorber, obtains real-time image data and transmits it to the shock absorber performance detection main body 1 for analysis. This design realizes the synchronous detection of the appearance and other performances of the shock absorber, further improves the comprehensiveness and accuracy of the detection, and helps to more comprehensively evaluate the performance of the shock absorber.

[0024] Working principle: During operation, first, according to the size of the shock absorber to be detected, the lateral electric push rod 21 and the lower clamping seat 3 are adjusted through the control end of the shock absorber performance detection main body 1, 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, the lower end of the shock absorber to be detected is inserted into the inside 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. Then, the shock absorber performance detection main body 1 will push the lateral electric push rod 21, so that it drives the performance detection structure 2 to move downward until the lower liquid ring 23 is sleeved on the upper end of the shock absorber. Then, the safety liquid circulation device is started to transport the safety liquid into the inside of the input liquid channel 231, so that the safety liquid flows in the input liquid channel 231, enters the space where the piston spring push rod 232 is located through the through holes on the annular path, and pushes the piston spring push rod 232 to extend outward, so that the anti-slip gasket 233 tightly fits on the upper end of the shock absorber, realizing the 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 port of the communication pipe 234, so that the communication pipe 234 is communicated with the input liquid channel 231. Then, the safety liquid will enter the output liquid channel 236 through the communication pipe 234 and enter the inside of the lifting liquid pipe 22 through the pipeline from the output liquid channel 236. As the safety liquid surges in, the hydraulic force increases, and the safety liquid will push the lifting piston spring sleeve rod 221 to compress the spring and move downward. As the lifting piston spring sleeve rod 221 moves downward, it will make the inside of the lifting liquid pipe 22 communicate with the first variable diameter liquid pipe group 222. Then, the safety liquid will enter the inside of the lower liquid guide pipe 223 through the first variable diameter liquid pipe group 222 and then flow into the lateral liquid pipe 24 through the pipeline. In the lateral liquid pipe 24, the safety liquid pushes the top push piston spring sleeve rod 241 to move toward the shock absorber main body direction. The detachable end of the output end of the top push piston spring sleeve rod 241 contacts the shock absorber main body and applies a thrust. Since the structural settings of the lateral liquid pipe 24, the top push piston spring sleeve rod 241, the second variable diameter liquid pipe group 242, and the lateral liquid guide pipe 243 are the same as the structural settings of the lifting liquid pipe 22, the lifting piston spring sleeve rod 221, the first variable diameter liquid pipe group 222, and the lower liquid guide pipe 223, the flow and action modes of the safety liquid in these components are similar. Therefore, the safety liquid will enter the notch chute 251 of the outer sleeve ring 25 from the lateral liquid guide pipe 243. In the notch chute 251, the safety liquid pushes the spring piston 253 to move along the inside of the notch chute 251, and the compressed and moved spring piston 253 will drive the rotating ring 254 and the detection camera 255 to rotate and move synchronously. The detection camera 255 will take pictures of the real-time appearance and working state of the shock absorber in the current state, obtain relevant image data, and transmit the data to the shock absorber performance detection main 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, realizing the recycling of the safety liquid; In the above process, technicians can control the pumping volume and efficiency of the safety liquid circulation device according to a pre-set program. The pumping volume and efficiency can be continuously increased, or they can fluctuate. During the change of the pumping volume and efficiency, as the safety liquid continuously flows and the pressure changes, in the lifting liquid pipe 22, the lifting piston spring sleeve rod 221 will continuously 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 continuously perform compression detection or vibration simulation in the up and down directions. At the same time, in the horizontal liquid pipe 24, the pushing piston spring sleeve rod 241 will continuously press the side of the shock absorber to perform lateral pressure detection on the shock absorber, or the pushing piston spring sleeve rod 241 will reciprocally push the pushing shock absorber to perform vibration simulation in the horizontal direction. In this way, the force conditions of the shock absorber in different directions can be simultaneously simulated. Through such a complete work process, the synchronous detection of multiple dimensions such as the appearance, static performance, and dynamic performance of the shock absorber of new energy vehicles is realized, greatly improving the detection efficiency and reducing the labor cost and equipment loss.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
