[0020] The present invention is further described in detail below with reference to the embodiments given in the accompanying drawings.

[0021] See also Figure 1-7 As shown, a windshield system simulates a car coupler, including a sliding assembly 1, an intermediate clamp assembly 2, a balance plate assembly 3 and a support rod 4, the sliding assembly 1 has two groups, which are respectively slidably arranged at the two ends of the support rod 4, the intermediate clamp assembly 2 is clamped and fixed on the support rod 4, the two ends of the balance plate assembly 3 are respectively pivotally connected to the sliding assembly 1 by screws, the balance plate assembly 3 includes two balance plates 1 3.3 and balance plates 2 3.5, the balance plates 2 3.5 are hinged to the intermediate clamp assembly 2, one end of the two balance plates 1 3.3 is respectively hinged to the two ends of the balance plates 2 3.5, and the other ends are respectively hinged to the corresponding sliding assemblies 1, the sliding assembly 1 is driven by the balance plate assembly 3 to slide on the support rod 4, so as to realize the windshield system simulates the stretching and compression action of the car coupler.

[0022] See also Figure 1 , 2 As shown in Figure 3, the sliding assembly 1 includes a rotating component 1.1, a pin shaft group 1.2, a side rolling component 1.3, a pin shaft group 2 1.4, a nodding component 1.5, a sliding component 1.6 and a sealing ring 1.7. The rotating component 1.1 is fixedly connected to the windshield system test bench by screws. The side rolling component 1.3 is a door-type frame. The rotating component 1.1 and the side rolling component 1.3 penetrate into the upper part of the side rolling component 1.3 through the pin shaft group 1.2 to achieve a 360° rotation connection in the Z direction. The nodding component 1.5 is also a door-type frame.

The nodding component 1.5 is sleeved on the shaft of the sliding component 1.6. The sealing ring 1.7 is fixedly connected to the sliding component 1.6 by screws. The sealing ring 1.7 is used to limit the wear-reducing sleeve 1.8 in the sliding hole of the sliding component 1.6.

[0023] like Figure 2The figure shows a schematic diagram of the normal state of the side rolling component 1.3. The rotating component 1.1 in the sliding assembly 1 can rotate 360° around the Z axis relative to the side rolling component 1.3 in the normal state, so as to meet the deflection test requirements of the windshield system; in the normal state of the sliding assembly 1, the side rolling component 1.3 is in a vertical state relative to the nodding component 1.5;

[0024] like Figure 4 The figure shows a schematic diagram of the side rolling component 1.3 rotating 7 degrees clockwise around the X-axis. In the sliding assembly 1, the side rolling component 1.3 rotates clockwise or counterclockwise around the X-axis relative to the nodding component 1.5 at a normal state between 0° and 7°, thereby meeting the forward or reverse rolling test requirements of the windshield system; when the rotatable angle formed by the side rolling component 1.3 and the nodding component 1.5 in the spatial position is greater than 7°, since the side rolling component 1.3 is a portal frame, the side rolling component 1.3 will interfere with the nodding component 1.5;

[0025] like Figure 5 As shown, the schematic diagram of the nodding component 1.5 rotating 7 degrees clockwise around the Y axis. In the sliding assembly 1, the nodding component 1.5 rotates clockwise around the Y axis at an angle E between 0° and 7° relative to the sliding component 1.6 in a normal state, so as to meet the forward or reverse nodding test requirements of the windshield system; when the rotatable angle formed by the nodding component 1.5 and the sliding component 1.6 in the spatial position is greater than 7°, the bottom of the side rolling component 1.3 will press against the upper part of the sliding component 1.6, and the side rolling component 1.3 will interfere with the sliding component 1.6.

[0026] See also Figure 6 As shown, the middle clamp assembly 2 includes a middle clamp 1 2.1, a middle clamp 2.2, a fixing plate 2.3, an adjusting stud group 2.4 and a support plate 2.5. The middle clamp 1 2.1 and the middle clamp 2 2.2 are fixedly connected by screws to form a clamping hole, and are clamped and fixed on the outer periphery of the middle part of the support rod 4. The fixing plate 2.3 is fixed to the middle clamp 2 2.2 by screws. The support plate 2.5 is connected to the fixing plate 2.3 by an adjusting screw group 2.4. The adjusting screw group 2.4 is composed of four groups of screws and nuts. The nuts are used to achieve height adjustment of the support plate 2.5.

[0027] See also Figure 7 As shown, the balance board assembly 3 also includes a balance board mounting seat 3.1, a pin shaft group 3.2, a pin shaft group 4 3.4, and an intermediate support seat 3.6. The balance board mounting seat 3.1 is hinged to the balance board 1 3.3 through the pin shaft group 3.2. The balance board mounting seat 3.1 is fixed on the corresponding sliding assembly 1. The balance board 2 3.5 is fixedly connected to the intermediate support seat 3.6 to form a whole. The intermediate support seat 3.6 is hinged to the intermediate clamp assembly 2.

[0028] See also Figure 3As shown, it also includes a wear-reducing component 1.9, a wear-reducing component 2 1.10 and a wear-reducing component 3 1.11. The wear-reducing component 1.9 is installed between the rotating component 1.1 and the side rolling component 1.3 through the pin shaft group 1.2, the wear-reducing component 2 1.10 is installed between the side rolling component 1.3 and the nodding component 1.5 through the pin shaft group 2 1.4, and the wear-reducing component 3 1.11 is fixedly connected with the nodding component 1.5 through screws and sleeved on the shaft of the sliding component 1.6. The rotating component 1.1, the side rolling component 1.3, the nodding component 1.5 and the sliding component 1.6 are made of 45# steel. The wear-reducing component 1.9, the wear-reducing component 2 1.10 and the wear-reducing component 3 1.11 are made of H62 brass. The contact between two materials of different hardness can better reduce the wear between the two components, greatly improving the service life of each component in the windshield system simulated car coupler. When the wear-reducing component is worn out, it only needs to be replaced, and the maintenance is simple and convenient to operate. This structural design does not require the entire sliding assembly 1 to be replaced, which can effectively save production costs.

[0029] In the present embodiment, the simulated hook of the windshield system is installed on the windshield system test bench, and the rotation point of the simulated hook of the windshield system in the Z direction can be adjusted to be consistent with the center distance of the hook of the windshield system through the windshield system test bench. This design reduces the relative sliding friction between the sliding assembly 1 of the simulated hook of the windshield system and the support rod 4 in the deflection test of the windshield system; at the same time, the simulated hook of the windshield system can satisfy the sliding of -200mm to 200mm based on the center distance of the hook in the X-axis direction. In this embodiment, a 2300mm hook center distance is used as an example to meet the test requirements of the windshield system tension and compression.

[0030] The windshield system simulation coupler is installed on the windshield system test bench. The windshield system simulation coupler can perform compound actions of stretching, compression, nodding, rolling and deflection with the windshield system. The windshield system simulation coupler can simultaneously complete a maximum rotation of 7 degrees clockwise around the Y-axis, 7 degrees clockwise around the X-axis, 38 degrees clockwise around the Z-axis, and a positive sliding movement of 200mm in the X-axis direction. It can also complete a maximum rotation of 7 degrees counterclockwise around the Y-axis, 7 degrees counterclockwise around the X-axis, 38 degrees counterclockwise around the Z-axis, and a negative sliding movement of 200mm in the X-axis direction. It can also complete a single action in any direction or any combination of actions in any direction; the overall structure of the windshield system will not sag, thereby improving the accuracy of the windshield system simulation experiment.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
