Description

Technical Field

[0002] A shock absorber is an important component in an automobile. Its main function is to suppress the oscillation when the elastic structure rebounds after absorbing shock and the impact from the road surface, so as to achieve the attenuation of the vibration of the frame and the body during acceleration, and improve the ride comfort of the automobile. The shock absorber achieves the purpose of shock absorption by converting the kinetic energy of the impact into heat energy and dissipating it. Some shock absorbers are airtight shock absorbers with a housing sealing structure. For some sealed shock absorbers, a sealing detection device is required to detect the shock absorber during use, mainly to detect the airtightness of the shock absorber housing to ensure the airtightness of the gas inside the shock absorber housing.

[0003] In the prior art for detecting sealed automotive shock absorbers, during the detection, the shock absorber and the housing are mostly in a static state, which cannot reflect the sealing condition of the shock absorber housing in the dynamic state, resulting in inaccurate detection results. Therefore, there is an urgent need for a deflection and jitter mechanism for housing detection to realize a device that can simulate the sealing performance of the sealed shock absorber housing in the dynamic state. Summary of the Invention

[0053] The shock absorber housing 11 is placed on the placing plate 6, the fixing mechanism fixes the shock absorber housing 11, the air pump 15 sends gas into the interior of the shock absorber housing 11, the pressure detector 13 detects the air pressure inside the shock absorber housing 11, so as to detect the airtightness of the shock absorber housing 11. Then, the deflection and jitter mechanism drives the shock absorber housing 11 to deflect and jitter, thereby simulating the motion state of the shock absorber housing 11 during the driving of the vehicle. After standing for a period of time, the pressure detector 13 detects the air pressure inside the shock absorber housing 11 again.

[0054] As an embodiment of the present invention, please refer to Figure 1 and Figure 3 , the fixing mechanism includes:

[0055] The threaded groove 7 is provided on the rotating folding rod 5;

[0060] As an embodiment of the present invention, please refer to Figure 1 , the deflection and jitter mechanism includes:

[0061] The driving member 16 is connected to the bottom plate 1;

[0062] The missing gear 17 is connected to the output end of the driving member 16;

[0063] The first toothed plate 18 is connected to the sliding rod 3 and is located outside the vertical cylinder 2, and the first toothed plate 18 meshes with the teeth on the missing gear 17;

[0065] The deflection assembly has one end connected to the bottom plate 1 and the other end connected to the rotating folding rod 5, and is used to drive the rotating folding rod 5 to rotate.

[0066] The driving member 16 drives the missing gear 17 to rotate. When the teeth on the missing gear 17 mesh with the first toothed plate 18, the missing gear 17 drives the first toothed plate 18 to move upward. At this time, the elastic member 19 undergoes elastic deformation. When the missing gear 17 rotates to not mesh with the first toothed plate 18, under the reaction force of the elastic member 19, the first toothed plate 18 moves downward, thereby driving the rotating folding rod 5 to move longitudinally back and forth. The deflection assembly drives the rotating folding rod 5 to rotate, so as to simulate the movement state of the shock absorber housing 11 during the driving process of the vehicle. The elastic member 19 can adopt a spring, a spring sheet, etc. The driving member 16 can adopt a stepping motor, a servo motor, etc.

[0068] The gear 20 is connected to the rotating folding rod 5;

[0069] The second toothed plate 21 is connected to the bottom plate 1 and meshes with the gear 20.

[0070] When the fixed folding rod 4 drives the rotating folding rod 5 to reciprocate up and down, the rotating folding rod 5 drives the gear 20 to reciprocate longitudinally. The gear 20 meshes with the second toothed plate 21, causing the gear 20 to rotate during its longitudinal movement. The gear 20 drives the rotating folding rod 5 to reciprocate rotationally, thereby driving the shock absorber housing 11 to reciprocate rotationally, so as to simulate the movement state of the shock absorber housing 11 during the driving of the vehicle, and then perform dynamic detection.

[0071] As an embodiment of the present invention, please refer to Figure 1 , a gasket is provided at the connection between the intake pipe 12 and the shock absorber housing 11.

[0072] The gasket provided ensures the sealing performance of the connection and avoids gas leakage.

[0073] The working principle of the present invention is as follows: Place the shock absorber housing 11 on the placement plate 6, rotate the threaded sleeve 8, so that the threaded sleeve 8 drives the rotating sleeve 9 to move downward, the rotating sleeve 9 drives the limiting folding rod 10 to move downward, so that the limiting folding rod 10 abuts against the top of the shock absorber housing 11, and cooperate with the placement plate 6 to fix the shock absorber housing 11. The air pump 15 sends gas into the shock absorber housing 11, and the pressure detector 13 detects the air pressure inside the shock absorber housing 11, so as to detect the airtightness of the shock absorber housing 11. The driving member 16 drives the missing gear 17 to rotate. When the teeth on the missing gear 17 mesh with the first toothed plate 18, the missing gear 17 drives the first toothed plate 18 to move upward. At this time, the elastic member 19 undergoes elastic deformation. When the missing gear 17 rotates to not mesh with the first toothed plate 18, under the reaction force of the elastic member 19, the first toothed plate 18 moves downward, thereby driving the rotating folding rod 5 to reciprocate longitudinally. The rotating folding rod 5 drives the gear 20 to reciprocate longitudinally and vibrate. The gear 20 meshes with the second toothed plate 21, causing the gear 20 to rotate during its longitudinal movement. The gear 20 drives the rotating folding rod 5 to reciprocate rotationally, thereby driving the shock absorber housing 11 to reciprocate rotationally, so as to simulate the movement state of the shock absorber housing 11 during the driving of the vehicle, and at the same time perform detection. After the movement, after standing for a period of time, the pressure detector 13 detects the air pressure inside the shock absorber housing 11 again.

[0074] The above is also a detection method based on the device, that is:

[0075] A detection method based on the shock absorber housing detection device as described above includes the following:

[0076] Place the shock absorber housing on the placement plate, rotate the threaded sleeve so that the threaded sleeve drives the rotating sleeve to move downward, and the rotating sleeve drives the limiting folding rod to move downward, making the limiting folding rod abut against the top of the shock absorber housing. Cooperating with the placement plate, the shock absorber housing is fixed. The air pump sends gas into the shock absorber housing, and the pressure detector detects the air pressure inside the shock absorber housing, thereby detecting the airtightness of the shock absorber housing. The driving member drives the missing gear to rotate. When the teeth on the missing gear engage with the first toothed plate, the missing gear drives the first toothed plate to move upward. At this time, the elastic member undergoes elastic deformation. When the missing gear rotates to disengage from the first toothed plate, under the reaction force of the elastic member, the first toothed plate moves downward, thereby driving the rotating folding rod to move longitudinally back and forth. The rotating folding rod drives the gear to vibrate longitudinally. The gear engages with the second toothed plate, causing the gear to rotate during the longitudinal movement. The gear drives the rotating folding rod to rotate back and forth, and then drives the shock absorber housing to rotate back and forth, thereby simulating the driving process of an automobile. The pressure detector 13 simultaneously detects the air pressure inside the shock absorber housing 11.

[0077] It also includes the motion state of the shock absorber housing. After remaining stationary for a period of time, the pressure detector detects the air pressure inside the shock absorber housing again, realizing effective detection of three states: static, dynamic, and static again after dynamic.

[0078] Based on the detection method of the device, automated detection is realized, and the detection of the motion state of the shock absorber housing during the driving process of an automobile is realized. The detection of three states: static, dynamic, and static again after dynamic is realized by one device in a continuous manner, which is very practical and ensures the accuracy of the airtightness detection of the shock absorber housing.
