[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0024] Reference Figure 1 and Figure 2 As shown, a load device for a steering mechanism according to this utility model includes: a load assembly 2, including a connecting seat 21, a movable seat 22, a first connecting plate 23, a second connecting plate 25, and an elastic member 24. The first connecting plate 23 is connected to the connecting seat 21, the second connecting plate 25 is connected to the movable seat 22, the movable seat 22 is slidably connected to the connecting seat 21, the second connecting plate 25 is located between the two first connecting plates 23, and the elastic member 24 is located between the first connecting plate 23 and the second connecting plate 25; and a connecting assembly 3, which is connected to the second connecting plate 25.

[0025] This embodiment provides a load device for a steering mechanism. The output end of the steering mechanism under test is connected to the connecting assembly 3. The steering mechanism is then activated, causing its output end to move. During this movement, one elastic element 24 is compressed, and the other elastic element 24 extends, thus applying a load to the output end of the steering mechanism. Test results are output through sensors within the steering mechanism. The movable seat 22 is slidably connected to the connecting seat 21, and elastic elements 24 are provided on both sides of the second connecting plate 25. This allows the output end of the steering mechanism to bear a load during movement, simulating the load generated by tire deformation and friction during steering mechanism operation. The second connecting plate 25, positioned between the two elastic elements 24, provides a large load while maintaining a small overall volume of the load assembly 2. This allows the load device for the steering mechanism to be placed in a temperature chamber for testing, enabling testing of the steering mechanism under different temperatures and humidity levels.

[0026] Reference Figure 1 As shown, the load device for the steering mechanism also includes a base 1, which is generally flat and has multiple connection holes 11.

[0027] Reference Figure 2 As shown, the load assembly 2 includes a connecting seat 21, a movable seat 22, a first connecting plate 23, a second connecting plate 25, and an elastic element 24. The connecting seat 21 is connected to the base 1. Specifically, the connecting seat 21 is connected to the connecting holes 11 by bolts. The multiple connecting holes 11 on the base 1 allow the connecting seat 21 to be connected to different positions on the base 1, thus enabling the load device to be adapted to steering mechanisms of different sizes. The movable seat 22 is slidably connected to the connecting seat 21. Specifically, the connecting seat 21 is provided with a slide rail, and a slider is connected to the bottom side of the movable seat 22. The slider is slidably connected to the slide rail, thereby allowing the movable seat 22 to be slidably connected to the connecting seat 21. The first connecting plate 23 is connected to the top side of the connecting seat 21, and the second connecting plate 25 is connected to the top side of the movable seat 22. The planes containing the first connecting plate 23 and the second connecting plate 25 are parallel, and the planes containing the first connecting plate 23 and the second connecting plate 25 are perpendicular to the plane containing the top side of the connecting seat 21. Two first connecting plates 23 are connected to the connecting seat 21, and a second connecting plate 25 is located between the two first connecting plates 23. An elastic element 24, which can be considered a spring, is located between the first connecting plate 23 and the second connecting plate 25. Both ends of the elastic element 24 abut against and connect to the first connecting plate 23 and the second connecting plate 25, respectively. That is, the load assembly 2 includes two elastic elements 24, located on opposite sides of the second connecting plate 25. The elongation and compression paths of the elastic element 24 are parallel to the movement path of the movable seat 22. A positioning post 28 is provided on the side of the first connecting plate 23 near the second connecting plate 25. The positioning post 28 is cylindrical, and the elastic element 24 is sleeved on the positioning post 28. The positioning post 28 guides the elastic element 24 during compression and elongation, preventing bending and limiting the extreme movement of the second connecting plate 25. By having two elastic elements 24 located on both sides of the second connecting plate 25, the load assembly 2 can provide a larger load. By increasing the number of elastic elements 24 or replacing the elastic elements 24, the load assembly 2 can provide a larger load. By reducing the number of elastic elements 24 or replacing the elastic elements 24, the load assembly 2 can provide a smaller load.

[0028] Reference Figure 3As shown, the movable seat 22 is also provided with a clearance opening 29 corresponding to the position of the elastic member 24. The edge of the clearance opening 29 is arc-shaped to cooperate with the elastic member 24. The clearance opening 29 allows the end of the elastic member 24 to abut against the second connecting plate 25, and at the same time, the end of the elastic member 24 can also abut against the movable seat 22, thereby preventing the second connecting plate 25 from being deformed or shaking due to excessive force. The arc-shaped edge of the clearance opening 29 prevents the elastic member 24 from rubbing against the edge of the clearance opening 29 during elongation and compression, thus avoiding damage caused by friction between the elastic member 24 and the edge of the movable seat 22. The second connecting plate 25 is connected between the two clearance openings 29.

[0029] Reference Figure 2 As shown, the load assembly 2 also includes a universal joint 26, which can be considered as a fisheye joint. The second connecting plate 25 is provided with a first oblong hole, which extends in a direction perpendicular to the top side of the movable seat 22. The universal joint 26 is connected to the first oblong hole, thereby enabling the position of the universal joint 26 to be adjusted.

[0030] Reference Figure 4 As shown, the connecting assembly 3 is connected to the universal joint 26. The connecting assembly 3 includes a connecting post 31, which is cylindrical in shape and passes through the connection position of the universal joint 26. Stops 32 are connected to the side walls at both ends of the connecting post 31. The stops 32 are annular in shape and fitted onto the connecting post 31, and are detachably connected to the connecting post 31. Specifically, the stops 32 and the connecting post 31 are threaded together. The plane of the end of the stops 32 is coplanar with the plane of the end of the connecting post 31. The stops 32 prevent the connecting post 31 from detaching from the universal joint 26. The connecting assembly 3 also includes a second pressure plate 33, which is connected to both ends of the connecting post 31, and a clamping space is formed between the second pressure plate 33 and the end of the connecting post 31. Specifically, the connecting assembly 3 includes a mounting hole that passes through the connecting post 31 and the second pressure plate 33 along the axial direction of the connecting post 31. When clamping and fixing the steering mechanism to be tested, the connecting part of the output end of the steering mechanism to be tested is clamped between the end of the second pressure plate 33 and the connecting column 31. That is, the connecting part of the output end of the steering mechanism to be tested is located in the clamping space. The long bolt is passed through the mounting hole and locked with the nut, thereby fixing the output end of the steering mechanism to be tested to the connecting assembly 3.

[0031] Reference Figure 5As shown, the load device for the steering mechanism also includes a support assembly 4, which includes a support column 41 with a positioning hole 43 at its end. Specifically, the support column 41 is cylindrical, and the positioning hole 43 is located at the top of the support column 41. The mounting hole on the steering mechanism under test corresponds to the positioning hole 43, and the mounting hole and positioning hole 43 are connected by bolts, thereby fixing the steering mechanism under test to the support column 41. The support assembly 4 also includes a third connecting plate 42, which is connected to the support column 41 and the third connecting plate 42. The third connecting plate 42 is connected to the connecting hole 11. Specifically, the third connecting plate 42 can be connected to the connecting plate by bolts, allowing the third connecting plate 42 to be connected to different positions on the base 1, thereby enabling the support assembly 4 to support steering mechanisms of different sizes under test. In this embodiment, four support assemblies 4 are connected to the base 1 according to the position and number of mounting holes on the steering mechanism under test. Depending on the structure of the steering mechanism under test, different positions and different numbers of support assemblies 4 can be connected to the base 1.

[0032] The support assembly 4 also includes a first pressure plate 44, which has a second oblong hole. The second oblong hole is bolted to a connecting hole 11 on the base 1. Specifically, the bolt is threaded into the connecting hole 11, and the bolt head abuts against the top side of the first pressure plate 44, thereby connecting the first pressure plate 44 to the connecting hole 11. The bottom side of the first pressure plate 44 abuts against the top side of the third connecting plate 42. The first pressure plate 44 makes the support assembly 4 more stable, and the second oblong hole facilitates the adjustment of the position of the first pressure plate 44. A pad 45 is provided on the side of the first pressure plate 44 near the base 1. The pad 45 abuts against the base 1. The pad 45 ensures that the first pressure plate 44 remains stable after abutting against the third connecting plate 42, preventing the first pressure plate 44 from tilting.

[0033] Reference Figure 2 As shown, preferably, the load assembly 2 includes a third pressure plate 27, which abuts against the connecting seat 21. The third pressure plate 27 has the same structure and operation as the first pressure plate 44, and will not be described again. The third pressure plate 27 makes the load assembly 2 more stable as a whole.

[0034] Preferably, the first connecting plate 23 is provided with a pressure detection element, which can be regarded as a pressure sensor. The end of the elastic member 24 abuts against the pressure detection element. The pressure detection element is connected to the controller. The value of the pressure detection element can help to detect and judge the steering mechanism.

[0035] Preferably, in this embodiment, two load components 2 are connected to the base 1, and the support component 4 is located between the two load components 2, so that the load can be detected at both output ends of the steering mechanism under test at the same time.

[0036] In use, connect the mounting hole on the steering mechanism to be tested to the positioning hole 43 on the support column 41, then clamp the connecting part of the output end of the steering mechanism to be tested between the second pressure plate 33 and the end of the connecting column 31, then start the steering mechanism to be tested to move the output end of the steering mechanism to be tested. At this time, one elastic element 24 is compressed and the other elastic element 24 is extended. The test result is output through the sensor in the steering mechanism to be tested.

[0037] The present invention discloses a load device for a steering mechanism, which is slidably connected to a connecting seat 21 via a movable seat 22. Elastic members 24 are provided on both sides of a second connecting plate 25, so that the output end of the steering mechanism under test can have a load during movement, thereby simulating the load generated by tire deformation and friction during the operation of the steering mechanism. The second connecting plate 25, positioned between the two elastic members 24, can provide a larger load while keeping the overall volume of the load assembly 2 small. This allows the load device for the steering mechanism to be placed in a temperature chamber for testing, enabling testing of the steering mechanism load device under different temperatures and humidity levels.

[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
