[0029] When working, the shock absorber detection device in the existing technology can effectively detect the shock absorber at room temperature. However, in actual situations, the car will be driven in different severe weather environments. Therefore, when the shock absorber is detected, different environmental conditions need to be added. In order to solve the problem of simulating extreme environments to detect the shock absorber, it is necessary to turn on the water pump and the first motor 15. Under the action of the water pump, the water in the water tank 16 is pumped to the connecting pipe 11 through the water pipe 12; the water flows through the connecting pipe 11 to the rotating nozzle 10, and finally the water flows through the rotating nozzle 10 and is sprayed on the shock absorber body 6; under the action of the first motor 15, the first motor 15 drives the second gear 14 to rotate through the output shaft, and the second gear 14 is meshed with the first gear 13, so the second gear 14 drives the first gear 13 to rotate, and the first gear 13 drives the rotating nozzle 10 to rotate, and the rotating nozzle 10 rotates to spray multiple shock absorber bodies 6, realizing the function of simulating extreme environments to detect shock absorbers.

[0030] Further, such as Figure 2 and Figure 5 As shown, the inner wall of the detection box 7 is connected and fixedly connected with a three-way pipe 18; the three-way pipe 18 extends and passes through the detection seat 1; one end of the three-way pipe 18 is connected and fixedly connected with a heating box 19; a heating wire is provided in the heating box 19; the other end of the three-way pipe 18 is connected and fixedly connected with a cooling box 20; a condenser is provided in the cooling box 20; fans are provided in both the heating box 19 and the cooling box 20.

[0031] During operation, in order to increase the test simulation conditions, two valves are provided on the three-way pipe 18. When the valve close to the heating box 19 is opened, the heating wire and the fan are turned on, the heating wire generates heat, and the fan blows the heat into the detection box 7 through the three-way pipe 18, so as to realize the detection of the shock absorber body 6 at high temperature; when the valve close to the cooling box 20 is opened, the condenser and the fan are turned on, the condenser generates cold air, and the fan blows the cold air into the detection box 7, so as to realize the detection of the shock absorber body 6 at low temperature.

[0032] Further, such as Figure 1 and Figure 5 As shown, four pillars 2 are fixed to the top of the detection base 1; a top plate 4 is commonly fixed to the top of the pillars 2; an electric push rod 5 is fixed to the top plate 4; the output shaft of the electric push rod 5 is fixed to a lifting plate 3; the lifting plate 3 slides on the four pillars 2, and one end of the shock absorber body 6 is inserted on the lifting plate 3.

[0033] During operation, the shock absorber body 6 is placed in the limiting cylinder 9. When testing is required, the electric push rod 5 is turned on. The electric push rod 5 pushes the lifting plate 3 downward through the output shaft. During the downward movement of the lifting plate 3, the lifting plate 3 slides on the pillar 2. The pillar 2 limits the lifting plate 3 in the vertical direction. During the downward movement of the lifting plate 3, the shock absorber body 6 is pressed downward to perform pressure testing on the shock absorber body 6.

[0035] During operation, when the car is driving, the road surface may be uneven. In order to simulate the uneven road surface, the second motor 28 needs to be turned on. The second motor 28 drives the rotating rod 27 to rotate through the output shaft, and the rotating rod 27 drives the cam block 26 to rotate. Due to the special shape of the cam block 26, when the cam block 26 contacts the groove at the bottom of the detection box 7, the detection box 7 will move up and down, thereby realizing the detection of the shock absorber body 6 under the condition of up and down movement.

[0036] Further, such as Figure 5 As shown, the two side walls of the detection seat 1 are provided with sliding grooves; sliding columns 22 are fixedly connected in the sliding grooves; slide plates 21 are slidably connected to the slide columns 22; one side wall of the slide plate 21 is fixedly connected to the outer side wall of the detection box 7; a spring 23 is sleeved on the outer side of the sliding column 22; the top of the spring 23 is fixedly connected to the bottom of the slide plate 21; the bottom of the spring 23 is fixedly connected to the bottom inner wall of the sliding groove.

[0037] During operation, when the cam block 26 pushes the detection box 7 to move up and down, the detection box 7 will move up and down, and the detection box 7 drives the slide plate 21 to move up and down.

[0038] Further, such as Figure 4 As shown, a surrounding frame 8 is fixedly connected to the bottom of the lifting plate 3 ; the outer side walls of the surrounding frame 8 are in close contact with the inner side walls of the detection box 7 .

[0039] During operation, the outer side walls of the surrounding frame 8 are in close contact with the inner side walls of the detection box 7 , and the surrounding frame 8 seals the detection box 7 , making it easy to quickly blow heat or cold air into the detection box 7 .

[0040] Further, such as Figure 4 As shown, two pressure sensors 24 are fixedly connected to the top of the detection box 7 ; the two pressure sensors 24 are symmetrically arranged; and the tops of the pressure sensors 24 are both in contact with the bottom of the lifting plate 3 .

[0041] During operation, when the lifting plate 3 is pressing the shock absorber body 6 , the pressure sensor 24 monitors the pressure in real time, so as to facilitate understanding of the pressure condition of the shock absorber body 6 .

[0042] Further, such as Figure 5 As shown, the bottom of the detection box 7 is sealed and connected to one end of a drain pipe 17 , and the other end of the drain pipe 17 is connected to the water tank 16 . The drain pipe 17 penetrates and is connected to the detection seat 1 .

[0043] During operation, in the process of spraying the shock absorber body 6, a large amount of water flow will be generated in the detection box 7. By setting a drain pipe 17, the drain pipe 17 discharges the water in the detection box 7 into the water tank 16, thereby realizing the recycling of water.

[0044] Working principle: Place the shock absorber body 6 in the limiting cylinder 9. When testing is required, turn on the electric push rod 5. The electric push rod 5 pushes the lifting plate 3 downward through the output shaft. During the downward movement of the lifting plate 3, the lifting plate 3 slides on the pillar 2. The pillar 2 limits the lifting plate 3 in the vertical direction. During the downward movement of the lifting plate 3, the shock absorber body 6 is pressed downward. During the process of the lifting plate 3 pressing the shock absorber body 6, the pressure sensor 24 monitors the pressure in real time, which is convenient for understanding the pressure condition of the shock absorber body 6 and realizing the compression of the shock absorber body 6. Force detection; in order to solve the problem of needing to simulate extreme environments to detect the shock absorber, it is necessary to turn on the water pump and the first motor 15. Under the action of the water pump, the water in the water tank 16 is pumped to the connecting pipe 11 through the water pipe 12; the water flows through the connecting pipe 11 to the rotating nozzle 10, and finally the water flows through the rotating nozzle 10 and is sprayed on the shock absorber body 6; under the action of the first motor 15, the first motor 15 drives the second gear 14 to rotate through the output shaft, and the second gear 14 is meshed with the first gear 13, so the second gear 14 drives the first gear 13 The first gear 13 drives the rotating spray head 10 to rotate, and the rotating spray head 10 rotates to spray multiple shock absorber bodies 6, realizing the function of simulating extreme environments to detect shock absorbers; in order to increase the test simulation conditions, two valves are provided on the three-way pipe 18. When the valve close to the heating box 19 is opened, the heating wire and the fan are turned on, the heating wire generates heat, and the fan blows the heat into the detection box 7 through the three-way pipe 18, so as to realize the detection of the shock absorber body 6 at high temperature; when the valve close to the cooling box 20 is opened, the condenser and the fan are turned on. The condenser generates cold air, and the fan blows the cold air into the detection box 7 to realize the detection of the shock absorber body 6 at low temperature; when the car is driving, the road surface may be uneven. In order to simulate the uneven road surface, the second motor 28 needs to be turned on. The second motor 28 drives the rotating rod 27 to rotate through the output shaft, and the rotating rod 27 drives the cam block 26 to rotate. Due to the special shape of the cam block 26, when the cam block 26 contacts the groove at the bottom of the detection box 7, the detection box 7 will move up and down, thereby realizing the detection of the shock absorber body 6 under the condition of up and down movement.

[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
