Description

Technical Field

[0001] This utility model relates to the field of air suspension equipment pressure calibration and testing technology, specifically a trolley for testing the pressure calibration of air suspension equipment. Background Technology

[0002] An air suspension system, also known as an air suspension device, is a device that uses an electronic control system and an air compressor to adjust the height of a car off the ground. It can adjust in real time according to road conditions, thereby buffering the impact of bumpy roads on the vehicle, reducing vibration amplitude, and making the vehicle drive more smoothly on uneven roads, thus improving the driving and riding comfort experience. During the production and processing of air suspension systems, their pressure needs to be tested to ensure the normal operation and safety of the equipment. A small trolley for testing the pressure of air suspension systems is usually used when testing the pressure.

[0003] However, there are still some shortcomings in the traditional trolleys used for calibrating the pressure of air suspension equipment. For example, when calibrating the pressure of air suspension equipment, the test is usually carried out in an environment with uneven ground. In this case, relying solely on the trolley for support will make it difficult to ensure the stability of the trolley during the test, which may lead to the trolley shaking violently or even overturning, resulting in inaccurate test data.

[0004] In view of this, the present invention solves the above-mentioned technical problems by proposing a trolley for detecting the pressure calibration of air suspension equipment. Utility Model Content

[0005] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for a trolley used for testing the pressure calibration of suspended equipment. By using multiple support plates, multiple support points can be added, thereby making the test more stable. Furthermore, the buffer pads can reduce the shaking and prevent overturning, thus helping to improve the accuracy of the test data and solving the problems mentioned in the background technology.

[0006] This utility model provides the following technical solution: a trolley for detecting the pressure calibration of an air suspension device, comprising: a trolley body, a detection plate fixed to the top of the trolley body, a pressure sensor fixed inside the detection plate, multiple storage slots opened at the bottom of the trolley body, multiple electric push rods fixed inside the storage slots, a mounting frame fixed to the telescopic end of the electric push rods, a drive motor fixed inside the mounting frame, a bidirectional lead screw fixed to the output end of the drive motor, two drive blocks threaded to the outer wall of the bidirectional lead screw, a support plate fixed to the top of the drive blocks, and a buffer pad fixed to the bottom of the support plate.

[0007] As a preferred embodiment of this utility model, a connecting plate is fixed to the bottom of the support plate, a plurality of springs are fixed to the bottom of the connecting plate, and a buffer rod is fixed to the bottom end of the springs.

[0008] As a preferred embodiment of this utility model, multiple hydraulic rods are fixed inside the vehicle body, and multiple storage frames are fixed at the bottom of the vehicle body. A base plate is provided inside the storage frame, and the top of the base plate is fixedly connected to the telescopic end of the hydraulic rod.

[0009] As a preferred embodiment of this utility model, the bottom of the base plate is fixed with an anti-slip pad.

[0010] As a preferred embodiment of this utility model, the inner wall of the storage tank is provided with limiting grooves on both sides, and the two sides of the mounting frame are fixed with limiting blocks, which are slidably connected to the inside of the limiting grooves.

[0011] As a preferred embodiment of this utility model, anti-collision guardrails are fixed on both sides of the vehicle body.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this utility model, after the trolley is moved to the underside of the suspended device to be inspected, the output end of the drive motor rotates clockwise, driving the bidirectional lead screw to rotate, thereby causing the drive blocks to move away from each other. This allows the support plate to move out from under the vehicle body. Then, the extension end of the electric push rod moves downward, driving the mounting frame downward, allowing the buffer pad to contact the ground. Therefore, multiple support plates can increase multiple support points, making the inspection more stable. Furthermore, the buffer pad can reduce the shaking and prevent overturning, thus helping to improve the accuracy of the inspection data. After the inspection, the output end of the drive motor rotates counterclockwise and the electric push rod retracts, allowing the support plate to be stored away, avoiding obstruction during movement and making the movement and inspection of the vehicle body smoother.

[0014] 2. In this utility model, the spring is compressed by the buffer rod, which makes the buffering effect of the support plate better, reduces the vibration force generated during the test, and improves the safety of the test.

[0015] 3. In this utility model, the extension and retraction of the hydraulic rod can drive the base plate to move, so that the anti-slip mat comes into contact with the ground, thereby allowing the height of the vehicle body to be adjusted to adapt to air suspension equipment of different heights or sizes, thus improving flexibility and practicality.

[0021] 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.

[0022] Example 1,

[0023] Please see Figure 1-4 As shown, a trolley for detecting the pressure calibration of an air suspension device includes: a vehicle body 1, cameras, lights, and radars are provided on both sides of the vehicle body 1, a detection plate 2 is fixed on the top of the vehicle body 1, a pressure sensor 3 is fixed inside the detection plate 2, multiple storage slots 4 are opened at the bottom of the vehicle body 1, multiple electric push rods 5 are fixed inside the storage slots 4, a mounting frame 6 is fixed to the telescopic end of the electric push rod 5, a drive motor 7 is fixed inside the mounting frame 6, a bidirectional lead screw 8 is fixed to the output end of the drive motor 7, two drive blocks 9 are threaded to the outer wall of the bidirectional lead screw 8, a support plate 10 is fixed to the top of the drive block 9, and a buffer pad 11 is fixed to the bottom of the support plate 10.

[0024] A connecting plate 12 is fixed to the bottom of the support plate 10, and multiple springs 13 are fixed to the bottom of the connecting plate 12. A buffer rod 14 is fixed to the bottom end of the springs 13.

[0025] Multiple hydraulic rods 15 are fixed inside the vehicle body 1, and multiple storage frames 16 are fixed at the bottom of the vehicle body 1. A base plate 17 is provided inside the storage frame 16, and the top of the base plate 17 is fixedly connected to the telescopic end of the hydraulic rod 15.

[0026] An anti-slip pad 18 is fixed to the bottom of the base plate 17.

[0027] In use, the trolley is first moved under the suspended device to be inspected. Then, the output of the drive motor 7 rotates clockwise, driving the bidirectional lead screw 8 to rotate, which causes the drive blocks 9 to move away from each other. This allows the support plate 10 to move out from under the vehicle body 1. Then, the extension end of the electric push rod 5 moves downward, driving the mounting frame 6 downward, which allows the buffer pad 11 to contact the ground. Therefore, multiple support plates 10 can increase multiple support points, making the inspection more stable. The buffer pad 11 also reduces the shaking and prevents overturning, thus helping to improve the accuracy of the inspection data. After the inspection, the output of the drive motor 7 rotates counterclockwise and the electric push rod 5 retracts, which allows the support plate 10 to be stored away, avoiding obstruction during movement and making the movement and inspection of the vehicle body 1 smoother.

[0028] By compressing the spring 13 with the buffer rod 14, the buffering effect of the support plate 10 can be improved, reducing the vibration force generated during the test and improving the safety of the test.

[0029] The extension and retraction of the hydraulic rod 15 can move the base plate 17, allowing the anti-slip mat 18 to contact the ground. This enables the height of the vehicle body 1 to be adjusted to accommodate air suspension equipment of different heights or sizes, thus improving flexibility and practicality.

[0030] Example 2,

[0031] For one specific embodiment of this utility model, please refer to Figure 1-4 As shown, limit grooves 19 are respectively opened on both sides of the inner wall of the storage tank 4, and limit blocks 20 are respectively fixed on both sides of the mounting frame 6. The limit blocks 20 are slidably connected to the inside of the limit grooves 19; anti-collision rails 21 are respectively fixed on both sides of the vehicle body 1.

[0032] During use, the sliding of the limiting block 20 in the limiting groove 19 can improve the stability of the mounting frame 6 when it moves up and down, avoid skewing, and prevent the position of the support plate 10 from deviating, thus helping to improve the support effect of the support plate 10; the anti-collision railing 21 can protect the two sides of the vehicle body 1 to avoid collision and damage during movement, and prevent it from affecting subsequent testing.
