Technical Field
[0001] This utility model relates to the field of shock absorber testing technology, specifically a testing device for the production of shock absorbers for electric tricycles. Background Technology
[0002] Electric vehicle shock absorbers are core components that function through hydraulic throttling and damping. They are mainly used to suppress rebound oscillations after spring shock absorption and to filter road impacts, thus ensuring driving stability.
[0003] Currently, electric vehicle shock absorbers need to undergo factory testing after production. In order to ensure environmental adaptability, a dustproof test is required to simulate the dustproof capability of the shock absorbers when outdoors. Specifically, a set of shock absorbers is placed in a dust treatment box for a period of time, and then taken out to test whether its damping performance is normal and rebounding. However, the current dustproof test simulation for shock absorbers is relatively simple and cannot perform additional tests, resulting in a lack of effectiveness in testing their environmental adaptability.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example: Figure 1-5 As shown, this utility model provides a testing device for the production of shock absorbers for electric tricycles, including a processing box 1. A door panel is rotatably installed on the front of the processing box 1. An air inlet pipe 5 and an air outlet pipe 51 are respectively installed at both ends of the processing box 1. A movable plate 13 is provided at the top inside the processing box 1. A fixing block 11 is fixedly connected between the lower surface of the movable plate 13 and the bottom inside the processing box 1. A horizontally arranged mounting rod 12 is fixedly installed on the fixing block 11. A shock absorber body 3 with testing is sleeved on the mounting rod 12. Vertically arranged uprights 14 are fixedly installed at both ends of the movable plate 13, and the top of the uprights 14 can move through the processing box 1. A push plate 15 is fixedly connected between the tops of the two uprights 14. Vertically arranged uprights 16 are fixedly installed on both sides of the push plate 15 in the processing box 1. A rotating shaft 17 is rotatably installed between the tops of the two uprights 16. A cam 18 is fixedly installed on the rotating shaft 17.
[0021] A movable frame 31 is movably inserted at the back of the treatment box 1. A collision block 32 is fixedly installed at one end of the movable frame 31 near each shock absorber body 3 on the outer wall of the treatment box 1. A connecting rod 33 is fixedly installed at the middle end of the movable frame 31 on the side away from the collision block 32. The connecting rod 33 movably passes through the treatment box 1 and is fixedly installed with a horizontally arranged movable plate 34. A rectangular groove 35 is opened through the movable plate 34. An arc-shaped groove 36 is opened on the rectangular groove 35 and is arranged diagonally. A Y-shaped push block 37 is rotatably installed at the middle end of the rectangular groove 35. A rotating rod 38 is fixedly installed at the middle end of the push block 37.
[0022] A first motor 19 is fixedly installed on one of the upright plates 16. The output end of the first motor 19 is coaxially fixed on the rotating shaft 17. The first motor 19 mainly provides power for the rotation of the rotating shaft 17, making it convenient for the staff to operate.
[0023] A stop block 21 is fixedly provided at the upper end of the upright 14. A reset spring 2 is sleeved on the upper end of the upright 14 at the processing box 1. The upper and lower ends of the reset spring 2 are fixedly provided on the stop block 21 and the processing box 1, respectively. The reset spring 2 is mainly used to provide power for the push plate 15 to move upward, so that the cam 18 can continuously push the push plate 15 downward.
[0024] An L-shaped support frame 4 is fixedly installed on the back of the processing box 1 below the movable plate 34. The other end of the movable plate 34 is movably inserted into the support frame 4. A second motor 39 is fixedly installed at the bottom of the support frame 4. The output end of the second motor 39 is coaxially fixed on the rotating rod 38. The support frame 4 effectively supports the movement of the movable plate 34, enabling it to move stably. The second motor 39 provides power for the rotation of the rotating rod 38, making it convenient for operators to control.
[0025] The back of the movable frame 31 is fixed with horizontally arranged support rods 311 at both ends of the connecting rod 33. The support rods 311 move through the processing box 1. The support rods 311 mainly support the movement of the movable frame 31. When the connecting rod 33 pushes the movable frame 31 to move, it is limited and supported by the support rods 311 at both ends, so that the movable frame 31 moves back and forth stably and ensures the smoothness of its movement.
[0026] Working principle: During use, the operator inserts the upper and lower ends of the shock absorber to be tested into the mounting rods 12 located at the upper and lower ends inside the treatment box 1, respectively. Figure 1 As shown, the door panel is then closed, and an external fan is connected to the end of the air inlet pipe 5. The fan blows in the dust, allowing the dust to enter the processing box 1. An external air pump can be connected to the air outlet pipe 51 to extract the dust, allowing the dust in the processing box 1 to move and be discharged normally, simulating the dust situation under the normal driving environment of an electric tricycle.
[0027] Subsequently, the first motor 19 and the second motor 39 are started. When the first motor 19 is working, it will drive the rotating shaft 17 to rotate. At this time, when the cam 18 fixed on the rotating shaft 17 rotates and contacts the push plate 15, it will squeeze and move downward. At this time, the uprights 14 fixed at both ends of the push plate 15 will push the moving plate 13 fixedly connected below to move downward. The moving plate 13 will squeeze the shock absorber body 3, so that the shock absorber body 3 simulates the state of being squeezed by gravity during operation.
[0028] The second motor 39, once started, will drive the rotating rod 38 to rotate. The rotating rod 38 will then drive the top-fixed push block 37 to rotate. One end of the push block 37 will first abut against the side wall of the rectangular groove 35. As the push block 37 rotates, it will push the movable plate 34 toward the side that contacts the rectangular groove 35. After the end of the push block 37 rotates into the adjacent arc groove 36, the other end of the push block 37 will contact the other side of the rectangular groove 35. At this time, the push block 37 will push the movable plate 34 back to its original position. As the second motor 39 drives the rotating rod 38 to rotate continuously, it will control the push block 37 to push the movable plate 34 to move rapidly and repeatedly. During this process, the connecting rod 33 fixed to the side wall of the movable plate 34 will push the movable frame 31 and cause the collision block 32 at its end to continuously collide with the corresponding shock absorber body 3. After the above operation, the surface of the shock absorber body 3 can be tapped during dustproof testing to simulate the collision of stones during the operation of an electric vehicle.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
