[0002] An automotive air spring is a device that uses compressed air as an elastic medium to achieve elastic support and shock absorption through the compressibility of air. Automotive air springs can help cars adapt to complex road conditions such as bumps, sudden braking, and cornering, as well as changes in load.

[0003] Automotive air springs use an electric pump to supply, regulate, and maintain compressed air, thereby enabling adjustments to vehicle height, changes in suspension stiffness, and stable system operation. To ensure the performance of the electric pump, it needs to be tested using testing equipment.

[0004] Existing testing equipment for automotive air spring electric pumps requires a power cord connected to a socket for power supply. However, it does not have a dedicated cord retraction function, and the power cord hangs freely. During handling and use, the power cord is easily stepped on, which can easily lead to damage to the cord over time and also poses a risk of tripping over workers. Utility Model Content

[0005] Given that the aforementioned testing equipment for automotive air spring electric pumps requires power to be supplied via a power cord connected to a socket, but lacks a dedicated cord rewinding function, and the power cord hangs freely, it is easily stepped on during handling and use. Long-term stepping on the power cord can easily lead to damage to the cord and also poses a risk of tripping over workers, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a testing device for an automotive air spring electric pump. By winding the power cord around the winding post and squeezing and fixing the power cord from the side using a limiting bracket, the orderly winding and fixing of the power cord is achieved, reducing the risk of power cord damage and the probability of tripping accidents.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1:

[0024] Reference Figures 1-3The first embodiment of this utility model provides a testing device for an electric air spring pump for automobiles, including a device body 1, a base plate 2 fixedly mounted on the device body 1, a winding post 3 fixedly connected to the side of the base plate 2 away from the device body 1, a wire hole 4 opened on the base plate 2 and the winding post 3, and an insertion block 5 fixedly connected to the side of the winding post 3 away from the base plate 2, and a limit frame 6 connected to the insertion block 5.

[0025] The limiting frame 6 is cross-shaped and has a positioning groove 7. The insert block 5 slides in the positioning groove 7. Example 2:

[0026] Reference Figures 2-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a limiting component 8 is provided on the side of the substrate 2 away from the device body 1. The limiting component 8 includes a baffle 801 and a limiting strip 802. The limiting strip 802 is made of elastic metal. The baffle 801 is fixedly connected to the substrate 2, and the limiting strip 802 is fixedly connected to the substrate 2. The baffle 801 has a limiting groove 803, and the limiting strip 802 has a bending portion 804.

[0027] The limit strip 802 has an L-shaped cross section, and the bent part 804 has a V-shaped cross section. Example 3:

[0028] Reference Figures 2-5 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that: a shielding cover 9 is inserted into the substrate 2, a limiting sleeve 10 is fixedly connected to the shielding cover 9, the limiting sleeve 10 is slidably engaged with the insert block 5, and a fixing component 11 is connected between the shielding cover 9 and the insert block 5.

[0029] The fixing component 11 includes a slot 1101, which is formed on the cover 9 and the insert 5. The cover 9 and the insert 5 have auxiliary grooves 1102, and the insert 5 has a rotating groove 1103. The slot 1101, the auxiliary groove 1102 and the rotating groove 1103 are interconnected. The slot 1101 is slidably connected to the insert rod 1104. The insert rod 1104 is fixedly installed with a limit block 1105. The insert rod 1104 is fixedly connected to the handle 1106. The limit block 1105 can slide in the auxiliary groove 1102 and can also rotate in the rotating groove.

[0030] When in use, first rotate the handle 1106. The handle 1106 drives the plug rod 1104 and the limiting block 1105 to rotate. The limiting block 1105 rotates in the rotating groove until the limiting block 1105 is aligned with the auxiliary groove 1102. At this time, the plug rod 1104 can be pulled out from the slot 1101. Then, the cover 9 is pulled off the plug block 5 to expose the power cord.

[0031] Remove the limit bracket 6 from the insert block 5, then press the bending part 804, the limit strip 802 deforms, causing the bending part 804 to exit from the limit groove 803, then pull out the power cord between the baffle 801 and the limit strip 802, and remove the power cord from the winding post 3 by rotating it, connect the plug of the power cord to the socket, and the device body 1 can be used.

[0032] When storing, wind the power cord around the winding post 3 and ensure that the plug of the power cord passes through the gap between the baffle 801 and the limiting strip 802. Then, move the limiting strip 802 so that the bent part 804 extends into the limiting groove 803. The limiting strip 802 returns to its original shape by its own elasticity, so that the bent part 804 abuts against the limiting groove 803, thereby limiting the power cord. Then, put the limiting bracket 6 on the plug block 5. The limiting bracket 6 squeezes and fixes the power cord from the side.

[0033] Finally, the cover 9 is placed on the insert block 5 using the limiting sleeve 10, and the insert rod 1104 is inserted into the slot 1101. At this time, the limiting block 1105 is inserted into the auxiliary slot 1102 along with the insert rod 1104. After the limiting block 1105 enters the rotating slot 1103, the handle 1106 is rotated to make the limiting block 1105 and the auxiliary slot 1102 misaligned. Due to the influence of gravity, the limiting block 1105 can prevent the cover 9 from separating from the insert block 5 without active operation.

[0034] The remaining structure is the same as that in Example 1. Example 4:

[0035] Reference Figure 1 and Figure 6 This is the fourth embodiment of the present invention. The difference between this embodiment and the previous embodiments is that the device body 1 is rotatably connected to a hinge 101. The hinge 101 is opened by rotation to expose the connector 102. Data transmission or detection is achieved through the connector 102 in conjunction with the line.

[0036] The device body 1 includes a tablet computer, a highly integrated programmable body device, the highly integrated programmable body device adopts a digital programmable power supply, an embedded integrated acquisition and control board, a local 2.8-inch touch screen display, an air tank, a distribution valve, a USB fast charging and heat dissipation; The embedded integrated acquisition and control board consists of an embedded MCU and logic processing circuit, a power acquisition circuit, a DC step-up and step-down power supply circuit, a low-voltage control circuit for high-voltage circuits, a safety protection circuit, and a communication circuit. The chassis consists of an all-aluminum alloy top cover and a floor tailplate. The embedded hidden handle is connected to the top cover, and each connector uses an aviation plug locking method, which can be quickly plugged in and unplugged with one hand. By setting the basic screen and tablet on the device, the voltage of the air pump and air valve can be adjusted, as well as the sensor calibration. When the device is powered off, the device can be operated in real time via Bluetooth communication through the APP on the tablet interactive computer. This allows personnel to maintain a safe distance from the machine, ensuring safety and ease of operation.

[0037] This portable programmable machine can be set up and operated via a tablet computer, thereby adjusting the power supply for the air pump and air valve to complete the operation process. It also allows for remote adjustment of sensor parameters and firmware upgrades. Simultaneously, the machine can fast charge the tablet, achieving multiple uses, safety, and intelligence. This solves the shortcomings of existing technologies that use separate power supplies for the air pump and air valve, as well as the problems of low integration of PLC and external circuit components, high energy consumption, inconvenient wiring connections, bulky machines, cumbersome operation and maintenance, and personnel issues.
