Description

Technical Field

[0001] This utility model relates to the field of automotive testing technology, and in particular to an automated testing device for automotive braking system performance. Background Technology

[0002] As a key component ensuring driving safety, the accurate testing of the automotive braking system's performance is crucial. Automotive braking system performance testing aims to comprehensively evaluate the braking system's performance under different operating conditions using specialized equipment and methods, covering core indicators such as braking force, braking distance, and braking response time, providing a reliable basis for safe driving.

[0003] However, current automotive braking system performance testing technology has many areas that urgently need improvement. In real-world testing scenarios, the complex and varied vehicle models and braking system structures place extremely high demands on the adaptability of testing equipment. Simultaneously, with the rapid increase in vehicle ownership and the growing emphasis on driving safety, the need for efficient and accurate testing is becoming increasingly urgent.

[0004] The existing technology has the following shortcomings:

[0005] 1) The braking systems of different brands and models of automobiles vary significantly in structure, size, and installation location. Traditional testing equipment is often designed only for specific types or some common models, lacking broad adaptability to diverse automotive braking systems. For example, some testing equipment has a fixed testing position, which cannot be flexibly adjusted to match the height and position of braking components of different models. This makes it difficult to conduct comprehensive and accurate testing on certain special models or newly launched models, seriously affecting the reliability and practicality of the test results. Utility Model Content

[0006] This invention uses an electric actuator to drive the top plate, which in turn drives the car and the testing instrument to precisely adjust their positions in the vertical direction. This can meet the differences in height and position of braking system components of different car models, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an automated testing device for automotive braking system performance, comprising a support base, two sets of outer shells fixedly connected to the top of the support base, a toothed column correspondingly and movably inserted inside the interior of each outer shell, a top plate fixedly connected to the top of each toothed column, a plurality of second connecting rods fixedly connected to the bottom of each top plate, a detector fixedly connected to the outer surface of each second connecting rod, a plurality of support platforms fixedly connected to the top of the support base, a limiting groove being formed on the opposite side of each support platform, a gear being movably inserted through the limiting groove in each support platform, and a first connecting rod fixedly connected to both ends of each gear.

[0008] Preferably, the outer surface of the housing has a slot, and the first connecting rod meshes with the toothed column through the slot.

[0009] Preferably, the top of the support base is fixedly connected to two vehicle ramps.

[0010] Preferably, the top of the support base is fixedly connected to multiple support frames.

[0011] Preferably, each of the support frames has a through plane fixedly connected to its top.

[0012] Preferably, the top of the support base is fixedly connected to two sets of brackets.

[0013] Preferably, each of the brackets is fixedly connected to the top of an electric actuator, and the top of each electric actuator is fixedly connected to the bottom of the top plate.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, the top plate driven by an electric push rod precisely adjusts the position of the car and the testing instrument in the vertical direction, accommodating the differences in the position of braking system components of different car models. By flexibly adjusting the position of the testing instrument, the testing is achieved, effectively solving the problem of poor adaptability of traditional testing equipment, greatly improving the reliability and practicality of the test results. The testing instrument automatically acquires various key performance indicators of the braking system, avoiding errors caused by manual operation and reading, and significantly improving the accuracy of the test data. At the same time, the automated testing process greatly shortens the testing time and improves the testing efficiency, which can well meet the needs of modern automobile production and repair enterprises for efficient testing, especially when the vehicle is being tested in batches.

[0016] 2. In this invention, when the electric actuator starts and drives the top plate to move, the toothed column at the bottom of the top plate transmits the motor's power to the gear through meshing with it. Since the gear meshes with multiple toothed columns simultaneously, the motor's power can be evenly distributed across each column, resulting in a relatively uniform force on each column. This uniform force distribution avoids imbalances caused by excessive or insufficient force on any single column, thus ensuring that the top plate remains level during ascent or descent and does not tilt. The second connecting rod and the detector connected to the bottom of the top plate can also move smoothly with the top plate, ensuring the accuracy and reliability of the detector during the detection process.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] As attached Figure 1 -Appendix Figure 5As shown, this utility model provides a technical solution: an automated testing device structure for automotive braking system performance, including a support base 1. Two sets of outer shells 2 are fixedly connected to the top of the support base 1. A toothed column 25 is correspondingly and movably inserted into the interior of each outer shell 2. A top plate 23 is fixedly connected to the top of each toothed column 25. Multiple second connecting rods 29 are fixedly connected to the bottom of each top plate 23. A detector 4 is fixedly connected to the outer surface of each second connecting rod 29. Multiple sets of support platforms 24 are fixedly connected to the top of the support base 1. Limiting grooves 28 are formed on opposite sides of each set of support platforms 24. Each set of support platforms 24 is movably connected through the limiting grooves 28. A gear 26 is movably inserted, with a first connecting rod 27 fixedly connected to both ends of the gear 26. This movable insertion method allows the gear 26 to rotate flexibly within the limiting groove 28, while being constrained by the limiting groove 28, ensuring the stability and accuracy of its rotation. This achieves efficient and stable power transmission between the gear column 25 and the gear 26, ensuring the smooth adjustment of the position of the detector 4. Multiple sets of support platforms 24 provide a stable support structure for the gear 26, ensuring that the gear 26 will not deviate or shake during rotation. It also enhances the stability of the entire device in the horizontal direction, ensuring that the overall structure of the device is solid and reliable during the test.

[0026] As attached Figure 1 -Appendix Figure 5 As shown, the outer surface of the outer shell 2 is provided with a slot 3. The first connecting rod 27 meshes with the toothed column 25 through the slot 3. The slot 3 provides space for the meshing of the first connecting rod 27 and the toothed column 25, so that the two can work closely together to achieve effective power transmission. This meshing method can not only accurately transmit the power of the electric push rod to the toothed column 25, driving the top plate 23 and the detector 4 to move, but also has a compact structure, occupies little space, and improves the space utilization of the device.

[0027] like Figure 1 and Figure 2 As shown, two vehicle ramps 11 are fixedly connected to the top of the support base 1. The two vehicle ramps 11 provide a convenient passage for the car to drive onto the testing device, guide the car to park accurately in the designated position, facilitate the subsequent braking system testing. At the same time, the design of the ramps allows the car to adjust its posture naturally during the climbing process, ensuring that the wheels are in the appropriate testing position and improving the accuracy of the test.

[0028] like Figure 1 and Figure 2 As shown, multiple support frames 12 are fixedly connected to the top of the support base 1. The multiple support frames 12 are evenly distributed on the top of the support base 1, providing stable support for the car and ensuring that the car will not shake or tilt during the test due to unstable support. This ensures the stability of the test environment and is conducive to obtaining accurate test data.

[0029] like Figure 1 and Figure 2 As shown, each support frame 12 is fixedly connected to a through plane 13 at its top. The through plane 13 provides a flat parking surface for the car, allowing the car to be placed stably on the testing device, reducing testing errors caused by uneven ground, and further improving the accuracy and reliability of the test.

[0030] As attached Figure 1 -Appendix Figure 5 As shown, two sets of brackets 21 are fixedly connected to the top of the support base 1. The two sets of brackets 21 provide a stable mounting position for the electric actuator 22, ensuring that the electric actuator 22 will not shift or shake during operation, thereby ensuring that the electric actuator can stably output power to drive the entire detection device to operate normally.

[0031] As attached Figure 1 -Appendix Figure 5 As shown, each bracket 21 is fixedly connected to an electric push rod 22. The top of each electric push rod 22 is fixedly connected to the bottom of the top plate 23. This connection between the electric push rod 22 and the top plate 23 allows the electric push rod to directly and effectively drive the top plate 23 to move up and down, simplifying the power transmission structure and improving the power transmission efficiency. At the same time, the direct connection reduces the energy loss and errors that may occur in the intermediate links, ensuring the accuracy and stability of the lifting and lowering of the top plate 23, thereby improving the accuracy of the position adjustment of the detector 4 and providing a strong guarantee for the accurate detection of the performance of the vehicle braking system.

[0032] Working principle: The electric actuator 22, serving as the power source for the entire device, is fixed to the top of the bracket 21. Its output shaft rotates to generate power. Transmission process: The top of the electric actuator 22 is connected to the bottom of the top plate 23. When the electric actuator 22 is activated, the rotation of its shaft drives the top plate 23 to move. Since the toothed column 25, fixedly connected to the bottom of the top plate 23, is inserted inside the outer casing 2, and the toothed column 25 meshes with the gear 26 on the first connecting rod 27 passing through the slot 3, the toothed column 25 moves accordingly when the electric actuator drives the top plate 23 to rise or fall. The vertical movement of the gear 25 is transmitted to the gear 26 via the connection between the gear 26 and the first connecting rod 27, causing the gear 26 to rotate within the limiting groove 28 of the support platform 24. The detector is connected as follows: multiple second connecting rods 29 are fixedly connected to the bottom of the top plate 23, and the detector 4 is fixedly connected to the outer surface of each second connecting rod 29. When the top plate 23 moves up and down due to the electric push rod 22, it drives the second connecting rods 29 and the connected detector 4 to move synchronously. Position adjustment is achieved by controlling the forward and reverse rotation of the electric push rod 22. The lifting and lowering of plate 23 allows for vertical adjustment of the position of the detector 4. This enables the detector 4 to be precisely moved to the appropriate position according to the height of different vehicle models and braking system components, facilitating comprehensive and accurate testing of the vehicle's braking system. Vehicle positioning: Two vehicle ramps 11 on the top of the support base 1 guide the vehicle slowly onto the testing device, ensuring the vehicle is accurately parked in the set position. The pass plane 13 on the top of the support frame 12 provides a stable parking plane for the vehicle, ensuring its stability during testing. Braking system testing: Once the vehicle is parked on the testing device as required, the electric push rod 22 is activated, driving the vehicle and detector 4 to the designated testing position. After the vehicle starts, all four wheels are suspended in the air, allowing for braking and driving. The detector 4 can automatically test relevant parameters of the vehicle's braking system, such as braking force, braking distance, and braking response time. Because the gear 26 rotates within the limiting groove 28, the entire testing device has good stability and guidance during operation, ensuring the accuracy of the test data.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
