Description

Technical Field

[0001] This invention relates to the field of automotive suspension technology, and more particularly to a suspension testing device. Background Technology

[0002] With the rapid increase in the number of family cars, the workload of car maintenance and repair is increasing. When a car reaches a certain mileage, the springs in the rear suspension will undergo permanent deformation, which will further cause changes in the tire camber angle, resulting in tire wear and a sag. If the spring deformation is small, it will affect the comfort of passengers. If the spring deformation is large, it will cause the car chassis to drop, making the car chassis more susceptible to scratches.

[0003] Existing suspension detection devices:

[0004] Prior art document CN106004296B discloses an emergency maintenance device for detecting rear suspension collapse in automobiles. In use, when the first spring, along with the first sensor at the connecting plate, moves downwards, and the first sensor contacts the second sensor, a timer causes the first and second electromagnets to attract the third and fourth electromagnets respectively. This results in the first and second positioning pins entering the first and second guide grooves respectively. At this point, the second spring drives the second top plate, which in turn pushes the first top plate in conjunction with the first spring, moving it upwards. This temporarily restores the first spring to its initial state. This emergency maintenance device for detecting rear suspension collapse in automobiles can restore the rear suspension to its initial state, protecting the vehicle's chassis and improving passenger comfort.

[0005] Although the suspension can be monitored and repaired while the car is in use, repairing it if a malfunction occurs while the car is in motion may affect the car's travel and could even cause the car to become uncontrollable and veer off course.

[0006] Therefore, we propose a suspension detection device that enables rapid clamping and release of tires to solve the aforementioned problems. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies where repairs to a fault occurring while the vehicle is in motion may affect the vehicle's travel distance or cause it to become uncontrollable and veer off course. This invention provides a suspension detection device.

[0008] To solve the above-mentioned technical problems, the present invention discloses a suspension detection device, including a clamping mechanism. The clamping mechanism includes two lead screws, each with two nuts threaded to its outer side. The four nuts are divided into groups of two, and anti-slip protrusions are provided on opposite sides of each pair of nuts. Thin rods are welded to the top and bottom of the two lead screws, and auxiliary rods are installed at the other ends of the four thin rods. A suspension body is clamped between each pair of anti-slip protrusions. A crossbar is connected between the two lead screws, and a support plate is installed on the outer side of the crossbar.

[0009] In a preferred embodiment, a first telescopic rod is installed on the top of the support plate, and a top plate is connected to the top of the first telescopic rod.

[0010] The technical effect of adopting the above-mentioned further solution is that the top plate is used to install the motor, so that the motor can remain stable during use.

[0011] In a preferred embodiment, a motor is fixed to the top of the top plate, a shaft is mounted on the output end of the motor, and a cam is mounted on the output end of the shaft.

[0012] The technical effect of adopting the above-mentioned further solution is that when the motor is connected to the power supply, the shaft can be rotated, so that the cam can rotate.

[0013] In a preferred embodiment, the top of the suspension body overlaps with the outer side of the cam.

[0014] The technical effect of adopting the above-mentioned further solution is that the cam fits against the outside of the suspension body, continuously squeezing the elastic mechanism on the suspension body, and monitoring the elasticity of the elastic mechanism on the suspension body.

[0015] In a preferred embodiment, a second telescopic rod is installed on the top of the support plate, and a limit rod is installed on the top of the second telescopic rod.

[0016] The technical effect of adopting the above-mentioned further solution is that the height of the cam and the touch counter can be adjusted by the first telescopic rod and the second telescopic rod, which can be applied to the height of the suspension body.

[0017] In a preferred embodiment, a touch counter is installed at the other end of the limiting rod, and the bottom of the touch counter is adapted to the top of the suspension body.

[0018] The technical effect of adopting the above-mentioned further solution is that when the elasticity of the elastic mechanism on the suspension body weakens, it may not be able to rebound to the initial height when it rebounds, so that the touch counter cannot contact the top of the elastic mechanism on the suspension body. At this time, it proves that the elastic mechanism on the suspension body can no longer be used and its performance needs to be improved.

[0019] Compared with the prior art, the advantages of this invention are:

[0020] The clamping mechanism clamps the outer side of the suspension body, allowing it to detect the elastic mechanism on the suspension body and assess its performance for improvement. The cam is attached to the outer side of the suspension body, continuously compressing the elastic mechanism and monitoring its elasticity. During this continuous compression, a touch counter monitors the number of presses and rebounds, thus monitoring the elastic mechanism on the suspension body.

[0021] The height of the cam and the touch counter can be adjusted using the first and second telescopic rods, which can be adapted to the height of the suspension body. When the elasticity of the elastic mechanism on the suspension body weakens, it may not be able to return to the initial height upon rebound, making it impossible for the touch counter to contact the top of the elastic mechanism on the suspension body. This indicates that the elastic mechanism on the suspension body is no longer usable and its performance needs to be monitored.

[0022] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0035] To better understand the purpose, structure, and function of this invention, the invention will be described in further detail below with reference to the accompanying drawings.

[0036] The present invention provides the following embodiments:

[0037] Example 1

[0038] This invention provides a suspension detection device; please refer to [link / reference]. Figure 1-4 The system includes a clamping mechanism 2, which includes two lead screws 21. Each lead screw 21 has two nuts 22 threadedly connected to its outer side. The four nuts 22 are divided into groups of two. Each pair of nuts 22 has anti-slip protrusions 23 on opposite sides. Thin rods 24 are welded to the top and bottom of the two lead screws 21. Auxiliary rods 25 are installed at the other end of each of the four thin rods 24. The suspension body 1 is clamped between each pair of anti-slip protrusions 23. A crossbar 26 is connected between the two lead screws 21. A support plate 27 is installed on the outer side of the crossbar 26.

[0039] The working principle and beneficial effects of the above technical solution are as follows: The clamping mechanism 2 clamps the outer side of the suspension body 1, allowing the clamping mechanism 2 to detect the elastic mechanism on the suspension body 1 and its performance, so as to improve it. During use, the nut 22 on the outer side of the lead screw 21 is moved towards the center of the lead screw 21, so that the anti-slip protrusions 23 on the nut 22 can clamp the outer side of the suspension body 1. When rotating the nut 22, the auxiliary rod 25 can be fixed by hand first, making it easier for the nut 22 to rotate on the outer side of the lead screw 21. At this time, the support plate 27 on the crossbar 26 on the outer side of the lead screw 21 is inserted... The first telescopic rod 3 on the support plate 27 is fixed and can be adjusted according to the height of the suspension body 1 so that the outer side of the cam 7 can be tightly attached to the top of the suspension body 1. At this time, the motor 5 is connected to the power supply so that the motor 5 rotates the shaft 6. When the shaft 6 rotates, the cam 7 can be rotated. The cam 7 is attached to the outer side of the suspension body 1, and the elastic mechanism on the suspension body 1 is continuously squeezed. The elasticity of the elastic mechanism on the suspension body 1 is monitored. When the elastic mechanism on the suspension body 1 is continuously squeezed, the touch counter 10 can monitor the number of presses and rebounds, thereby monitoring the elastic mechanism on the suspension body 1.

[0040] Example 2

[0041] Based on Embodiment 1, a first telescopic rod 3 is installed on the top of the support plate 27, and a top plate 4 is connected to the top of the first telescopic rod 3.

[0042] The working principle and beneficial effects of the above technical solution are as follows: the top plate is used to install the motor, so that the motor can remain stable during use.

[0043] Example 3

[0044] Based on embodiment 2, a motor 5 is fixed to the top of the top plate 4, a shaft 6 is installed at the output end of the motor 5, and a cam 7 is installed at the output end of the shaft 6.

[0045] The working principle and beneficial effects of the above technical solution are as follows: When the motor is connected to the power supply, the shaft can be rotated, so that the cam can rotate.

[0046] Example 4

[0047] Based on embodiment 3, the top of the suspension body 1 overlaps with the outer side of the cam 7.

[0048] The working principle and beneficial effects of the above technical solution are as follows: the cam is attached to the outside of the suspension body, and the elastic mechanism on the suspension body is continuously squeezed to monitor the elasticity of the elastic mechanism on the suspension body.

[0049] Example 5

[0050] Based on embodiment 4, a second telescopic rod 8 is installed on the top of the support plate 27, and a limit rod 9 is installed on the top of the second telescopic rod 8.

[0051] The working principle and beneficial effects of the above technical solution are as follows: the height of the cam and the touch counter can be adjusted by the first telescopic rod and the second telescopic rod, which can be applied to the height of the suspension body.

[0052] Example 6

[0053] Based on embodiment 5, a touch counter 10 is installed at the other end of the limiting rod 9, and the bottom of the touch counter 10 is adapted to the top of the suspension body 1.

[0054] The working principle and beneficial effects of the above technical solution are as follows: When the elasticity of the elastic mechanism on the suspension body weakens, it may not be able to rebound to the initial height when it rebounds, so that the touch counter cannot contact the top of the elastic mechanism on the suspension body. At this time, it proves that the elastic mechanism on the suspension body can no longer be used and its performance needs to be improved.

[0055] The above solutions also have the problem of not being able to adjust the clamping mechanism according to the height of the suspension body 1, such as... Figure 2 As shown: A first telescopic rod 3 is installed on the top of the support plate 27. A top plate 4 is connected to the top of the first telescopic rod 3. A motor 5 is fixed on the top of the top plate 4. A shaft 6 is installed at the output end of the motor 5. A cam 7 is installed at the output end of the shaft 6. The top of the suspension body 1 overlaps with the outer side of the cam 7. The motor 5 is connected to the power supply, so that the motor 5 rotates the shaft 6. When the shaft 6 rotates, it can rotate the cam 7. The cam 7 fits against the outer side of the suspension body 1, continuously squeezing the elastic mechanism on the suspension body 1, and monitoring the elasticity of the elastic mechanism on the suspension body 1.

[0056] Going further, such as Figure 2As shown: A second telescopic rod 8 is installed on the top of the support plate 27, and a limit rod 9 is installed on the top of the second telescopic rod 8. A touch counter 10 is installed on the other end of the limit rod 9. The bottom of the touch counter 10 is adapted to the top of the suspension body 1. The advantage of this technical solution is that the height of the cam 7 and the touch counter 10 can be adjusted by the first telescopic rod 3 and the second telescopic rod 8, which can be adapted to the height of the suspension body 1. When the elasticity of the elastic mechanism on the suspension body 1 weakens, it may not be able to rise back to the initial height when it rebounds, so that the touch counter 10 cannot contact the top of the elastic mechanism on the suspension body 1. At this time, it is proven that the elastic mechanism on the suspension body 1 can no longer be used and its performance needs to be improved.

[0057] like Figure 1-4 As shown, its working principle is:

[0058] The suspension testing device uses a clamping mechanism 2 to clamp the outer side of the suspension body 1, allowing the clamping mechanism 2 to detect the elastic mechanism on the suspension body 1 and assess its performance for improvement. During use, the nut 22 on the outer side of the lead screw 21 is moved towards the center of the lead screw 21, so that the anti-slip protrusions 23 on the nut 22 clamp the outer side of the suspension body 1. When rotating the nut 22, the auxiliary rod 25 can be manually fixed first, facilitating the rotation of the nut 22 on the outer side of the lead screw 21. At this time, the support plate 27 on the crossbar 26 on the outer side of the lead screw 21 is fixed to provide support. The first telescopic rod 3 on plate 27 can be adjusted according to the height of the suspension body 1 so that the outer side of the cam 7 can be tightly attached to the top of the suspension body 1. At this time, the motor 5 is connected to the power supply so that the motor 5 rotates the shaft 6. When the shaft 6 rotates, the cam 7 can be rotated. The cam 7 is attached to the outer side of the suspension body 1, and the elastic mechanism on the suspension body 1 is continuously squeezed. The elasticity of the elastic mechanism on the suspension body 1 is monitored. When the elastic mechanism on the suspension body 1 is continuously squeezed, the touch counter 10 can monitor the number of presses and rebounds, thereby monitoring the elastic mechanism on the suspension body 1.

[0059] The suspension detection device can adjust the height of the cam 7 and the touch counter 10 through the first telescopic rod 3 and the second telescopic rod 8. It can be adapted to the height of the suspension body 1. When the elasticity of the elastic mechanism on the suspension body 1 weakens, it may not be able to return to the initial height when it rebounds, so that the touch counter 10 cannot contact the top of the elastic mechanism on the suspension body 1. At this time, it proves that the elastic mechanism on the suspension body 1 can no longer be used and its performance needs to be improved.

[0060] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
