[0037] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example

[0038] like Figure 1-4 As shown, a vehicle chassis abnormal noise inspection system includes: a base plate 1, a support plate 3, and a rocker arm 2.

[0039] The support plate 3 is positioned above the base plate 1 and is slidably connected to the surface of the base plate 1. The base plate 1 has mounting holes that penetrate vertically through it.

[0040] It should be noted that, to ensure minimal friction between the surfaces of the support plate 3 and the base plate 1, a self-lubricating material is used in the contact area. For example, a self-lubricating coating, such as lubricating oil, graphite, or polytetrafluoroethylene, can be applied to the contact area between the support plate 3 and the base plate 1. Alternatively, a self-lubricating material with a certain rigidity and strength can be used in the contact area between the support plate 3 and the base plate 1. For example, a metal-based self-lubricating material can be made by using copper, iron, aluminum, or other metals as the matrix, adding lubricating phases such as graphite, molybdenum disulfide (MoS2), lead, and tin, and then composited through powder metallurgy or casting. Since self-lubricating materials are a conventional existing technology, they will not be elaborated upon further here.

[0041] The lower end of the rocker arm 2 is a grip portion 24, and the upper end is a ball head 23. The space between the ball head 23 and the grip portion 24 is the rod body portion 21. The size of the mounting hole is larger than the size of the rod body portion 21, allowing the rod body portion 21 to pass through the mounting hole. At the same time, the rod body portion 21 and the base plate 1 form a ball joint structure. In addition, the ball head 23 and the support plate 3 form a ball joint structure.

[0042] The vehicle chassis noise inspection system is configured to drive the support plate 3 to translate relative to the base plate 1 by shaking the rocker arm 2.

[0043] Furthermore, an automotive chassis noise inspection system also includes a first hinge seat 4 fixedly connected to the bottom surface of the support plate 3 and a second hinge seat 5 fixedly connected to the base plate 1. The first hinge seat 4 includes a first hinge seat cavity, and a ball head 23 is disposed within the first hinge seat cavity 4, forming a ball joint structure with the first hinge seat cavity 4. The second hinge seat 5 includes a second hinge seat cavity that extends vertically through itself, and the second hinge seat cavity 5 communicates vertically with the mounting hole. The rocker arm 2 also includes a ball table body 22 fixedly connected to the rod body 21, and the ball table body 22 is disposed within the second hinge seat cavity 5, forming a ball joint structure with the second hinge seat cavity 5. Here, the ball table body 22 is a ball table body with the upper and lower ends of the ball cut off, retaining the upper part of the structure above the horizontal plane where the great circle of the ball is located and the lower part of the structure.

[0044] When inspecting for abnormal noises from the car chassis, park the vehicle on top of the support plate 3 and place the wheels on the surface of the support plate 3. Shake the grip 24 to rotate the ball joint 22 relative to the second hinge seat cavity 5, thereby moving the ball head 23. The ball head 23, through its ball hinge with the first hinge seat 4, moves the support plate 3. Simultaneously, because the support plate 3 is slidably connected to the surface of the base plate 1, the support plate 3 can move the chassis connected to the car tires, thus enabling the inspection of abnormal noises from the car chassis.

[0045] Example 2

[0046] Example 2 is the same as Example 1. The only difference is that, Figure 5 and Figure 6 As shown, an automotive chassis noise inspection system further includes a rolling assembly 6 for supporting a support plate 3. The rolling assembly 6 is disposed between the base plate 1 and the support plate 3. Relying on the supporting action of the rolling assembly 6, the support plate 3 can translate relative to the base plate 1 under the action of external force. At the same time, when the support plate 3 translates relative to the base plate 1, the rolling action of the rolling assembly 6 can effectively reduce the friction between the two.

[0047] The rolling assembly 6 includes several omnidirectional conveying balls; each omnidirectional conveying ball includes a base with a mounting cavity and rolling balls, which are rotatably disposed within the mounting cavity. The base is fixedly connected to the base plate 1, so that the rolling balls of the omnidirectional conveying ball contact the lower surface of the support plate 3. Since the omnidirectional conveying balls are existing container goods, further details will not be provided here.

[0048] Preferably, the omnidirectional conveying balls are fixed in an array between the base plate 1 and the support plate 3.

[0049] Example 3

[0050] Example 3 is the same as Example 2. The only difference is that, Figure 7 and Figure 8As shown, the rolling assembly 6 includes several universal conveying balls; the universal conveying ball includes a seat with a mounting cavity and a ball bearing, which is rolled within the mounting cavity; the seat is fixedly connected to the support plate 3, so that the ball bearing of the universal conveying ball contacts the upper surface of the base plate 1.

[0051] Example 4

[0052] Example 4 is the same as Example 2 or Example 3. The only difference is that, Figure 9 As shown, the rolling assembly 6 includes omnidirectional conveyor balls, and these omnidirectional conveyor balls are arranged into several groups, allowing them to be used in groups, thereby improving the efficiency of installation, maintenance, and replacement of the rolling assembly 6. The base of each omnidirectional conveyor ball group is fixed to a fixed base plate 7, which is fixed to the upper surface of the base plate 1 or the lower surface of the support plate 3. Furthermore, to ensure that the omnidirectional conveyor balls are used in groups, each group contains at least two omnidirectional conveyor balls.

[0053] Example 5

[0054] Example 4 is the same as any of Examples 1-3. The only difference is that, Figure 10-11 As shown, an abnormal noise inspection system for a car chassis also includes a linkage mechanism 8 for limiting the translational direction of the support plate 3. By relying on the limiting effect of the linkage mechanism 8, the movement distance between the support plate 3 and the base plate 1 can be limited, reducing the vertical force between the ball head 23 and the base plate 1, and preventing the support plate 3 from separating from the base plate 1.

[0055] In this embodiment, the linkage mechanism 8 includes a fixed base 81, a fixed rod 82, a first vertical rod 83, a first joint bearing 84, a movable crossbar 85, a second joint bearing 86, and a second vertical rod 87.

[0056] The system includes two fixed bases 81, both of which are fixedly connected to the base plate 1. A fixed rod 82 passes through both fixed bases 81 and is fixedly connected to them. There are two first vertical rods 83, which are vertically arranged, with their upper parts fixedly connected to the fixed rods 82 and their lower parts fixedly connected to the first joint bearing 84. There are two movable crossbars 85, which are horizontally arranged, with one end fixedly connected to the first joint bearing 84 and the other end fixedly connected to the second joint bearing 86. The base plate 1 has a connecting rod mounting hole 11 for the second vertical rod 87 to pass through. The second vertical rod 87 passes through the connecting rod mounting hole 11, with its lower part fixedly connected to 86 and its upper end fixedly connected to the base plate 1.

[0057] Furthermore, the first spherical bearing 84 and the second spherical bearing 86 are preferably fisheye bearings. Fisheye bearings utilize the characteristics of spherical contact to allow the connected components to swing in multiple directions (such as tilting or deflecting) around the center of the sphere. They can transmit axial and radial forces and accommodate small angular deviations at the connection points, avoiding additional stress caused by rigid connections.

[0058] Example 6

[0059] Based on the same inventive concept, this utility model also provides a vehicle chassis abnormal noise inspection device, including the vehicle chassis abnormal noise inspection system in embodiment 5 and a scissor lift. The vehicle chassis abnormal noise inspection system is installed on the load-bearing platform of the scissor lift. The scissor lift can lift the vehicle, improving the convenience for maintenance personnel to inspect the vehicle chassis.

[0060] Furthermore, the base plate 1 of the vehicle chassis noise inspection system is fixedly connected to the upper surface of the load-bearing platform of the scissor lift, or the load-bearing platform plate of the scissor lift serves as the base plate 1 of the vehicle chassis noise inspection system.
