[0027] In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

[0028] Secondly, "one embodiment" or "embodiment" referred to herein means that a specific feature, structure or characteristic can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in this specification does not mean the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments.

[0029] Reference Figures 1-4 A multi-degree-of-freedom adjustment detection device for a steering column is provided, which includes a detection assembly 200. The detection assembly 200 accurately detects the position of the pipe column to improve the adjustment accuracy.

[0030] Specifically, the main body assembly 100 includes an upper support 101, a lower support 102, a fixed plate 103, and a pipe column assembly 104. The upper support 101 is arranged on one side of the pipe column assembly 104, the lower support 102 is arranged on the other side of the pipe column assembly 104, the fixed plate 103 is fixedly connected to the bottom of the lower support 102, and is sleeved on the surface of the pipe column assembly 104; and,

[0031] The detection assembly 200 is arranged on one side of the fixed plate 103 and includes a mounting plate 201, micro switches 202, a dismounting piece 203 and a docking piece 204. The mounting plate 201 is arranged on one side of the fixed plate 103. The micro switches 202 are arranged on the top and bottom of one side of the mounting plate 201. The dismounting piece 203 is arranged on one side of the micro switches 202. The docking piece 204 is arranged on the other side of the micro switches 202.

[0032] The main assembly 100 constitutes the basic structural framework of the steering column detection device. The upper bracket 101 and the lower bracket 102 respectively support the pipe column assembly 104 on both sides. The fixed plate 103 is sleeved on the surface of the pipe column assembly 104 and connected with the lower bracket 102 to provide a mounting base for the detection assembly 200. The detection assembly 200 is arranged on one side of the fixed plate 103. The mounting plate 201 is used to fix the micro switches 202, the dismounting piece 203 and the docking piece 204 to make the components work together and provide stable structural support for the entire detection device, and determine the installation position of each component to provide a basic condition for subsequent detection of the position of the pipe column.

[0033] Specifically, the micro switches 202 are arranged symmetrically on the top and bottom of the pipe column assembly 104.

[0034] When the angle of the steering column changes, the pipe column assembly 104 will move or rotate accordingly, thereby triggering the micro switches 202 on the top or bottom. Since the two groups of micro switches 202 are symmetrically arranged, at least one micro switch 202 will act when the angle of the pipe column is adjusted in any direction. Through the two groups of symmetrically arranged micro switches 202, the angle change of the steering column can be detected in all directions and accurately. Compared with the existing technology which relies on mechanical limiting devices to determine the position, the accuracy and sensitivity of the detection are greatly improved, so that the driver can accurately know the adjustment direction and position of the pipe column, which helps to adjust the pipe column to the appropriate position and improves the safety and comfort of driving.

[0035] Specifically, the dismounting piece 203 includes a clamping rod 203a fixedly connected to one side of the micro switch 202. The mounting plate 201 is provided with clamping holes 203b on the top and bottom of one side. The mounting plate 201 is provided with clamping blocks 203c on the top and bottom of the other side. The clamping rod 203a penetrates through the clamping holes 203b and the clamping blocks 203c and extends into the inner cavity of the clamping blocks 203c. The inner cavity of the clamping blocks 203c is provided with an ejection portion 203d on one side.

[0036] When installing the micro switch 202, the clamping rod 203a is inserted into the clamping hole 203b, and after the clamping rod 203a passes through the clamping hole 203b, the clamping rod 203a enters the inner cavity of the clamping block 203c, thereby realizing the preliminary fixation of the micro switch 202 and the mounting plate 201, and when disassembling, the ejection part 203d plays a role in pushing the clamping rod 203a out of the inner cavity of the clamping block 203c, so that the micro switch 202 is separated from the mounting plate 201, thereby solving the problems of difficult installation and disassembly, time-consuming of the micro switch 202 in the prior art, facilitating the maintenance and repair of the equipment, improving the work efficiency, and ensuring the stability and reliability of the micro switch 202 in the use process.

[0037] Specifically, the ejection part 203d includes an ejection block 203d-1 attached to the end of the clamping rod 203a, and a first spring 203d-2 is fixedly connected to one side of the ejection block 203d-1, and one side of the first spring 203d-2 is fixedly connected to one side of the inner cavity of the clamping block 203c.

[0038] Through the cooperation of the first spring 203d-2 and the ejection block 203d-1, the automatic ejection function of the clamping rod 203a is realized, the disassembly process of the micro switch 202 is further simplified, the manpower is saved, the disassembly efficiency is improved, and the maintenance of the micro switch 202 is more convenient and fast.

[0039] Specifically, the ejection part 203d further includes a sliding block 203d-3 fixedly connected to the top and bottom of the ejection block 203d-1, and the top and bottom of the inner cavity of the clamping block 203c are provided with sliding grooves 203d-4 matched with the sliding block 203d-3.

[0040] When the ejection block 203d-1 is pushed by the first spring 203d-2, the sliding block 203d-3 slides in the sliding groove 203d-4, providing guidance and support for the movement of the ejection block 203d-1, so that the ejection block 203d-1 can smoothly push the clamping rod 203a along a straight line.

[0041] Specifically, the dismounting piece 203 further includes a clamping groove 203e provided on the surface of the clamping rod 203a, and a triangular block 203f is clamped in the inner cavity of the clamping groove 203e, one side of the triangular block 203f penetrates through the clamping block 203c, and a pull ring 203g is fixedly connected.

[0042] When installing the micro switch 202, the triangular block 203f is clamped in the clamping groove 203e, so that the clamping rod 203a is stably fixed in the clamping block 203c, and when disassembling, the pull ring 203g is pulled, the pull ring 203g drives the triangular block 203f to exit from the clamping groove 203e, thereby releasing the fixation of the clamping rod 203a, and at this time, the ejection part 203d can eject the clamping rod 203a.

[0043] Specifically, the dismounting piece 203 further comprises a second spring 203h sleeved on the surface of the triangular block 203f, one side of the second spring 203h is fixedly connected with the pull ring 203g, and the other side of the second spring 203h is fixedly connected with the clamping block 203c.

[0044] When the micro switch 202 is installed, the second spring 203h is in a stretched state, so that the triangular block 203f is tightly clamped in the clamping groove 203e; when the micro switch 202 is dismounted by pulling the pull ring 203g, the second spring 203h is further stretched; when the pull ring 203g is released, the second spring 203h restores the deformation, pushes the pull ring 203g and the triangular block 203f back to the initial position, and facilitates the next installation.

[0045] Specifically, the butt joint piece 204 comprises a butt joint rod 204a fixedly connected to the other side of the micro switch 202, and the top and bottom of one side of the mounting plate 201 are provided with butt joint holes 204b matched with the butt joint rod 204a.

[0046] When the micro switch 202 is installed, the butt joint rod 204a is inserted into the butt joint hole 204b, so that the micro switch 202 is accurately butted and fixed with the mounting plate 201, and the micro switch 202 can be stably installed on the mounting plate 201.

[0047] Specifically, one side of the mounting plate 201 is provided with a mounting bolt 201a, and the mounting plate 201 is fixedly connected with the fixed plate 103 through the mounting bolt 201a.

[0048] The mounting bolt 201a ensures the reliable connection between the mounting plate 201 and the fixed plate 103, so that the detection assembly 200 can be stably installed on the main body assembly 100, and the detection device provides stable structural support, ensures the normal work of the detection device, and accurately detects the position change of the pipe column.

[0049] Specifically, the mounting bolt 201a has two groups and is symmetrically arranged on one side of the mounting plate 201.

[0050] The two groups of symmetrically arranged mounting bolts 201a are uniformly distributed on one side of the mounting plate 201, and when the mounting bolt 201a is tightened, the mounting plate 201 can be uniformly fastened, so that the connection between the mounting plate 201 and the fixed plate 103 is more closely and stably.

[0051] In use, when the pipe column assembly 104 changes in angle, since the two groups of micro switches 202 are symmetrically arranged on the top and bottom of the pipe column assembly 104, the movement or rotation of the pipe column will trigger at least one micro switch 202 to act, so as to realize the detection of the angle change of the pipe column; on the contrary, if the micro switch 202 is not triggered, it indicates that the pipe column assembly 104 is in the initial state, and the steering feel and various performances of the steering column are in the optimal state.

[0052] In the installation process of the micro switch 202, the clamping rod 203a is inserted into the clamping hole 203b on the mounting plate 201, and after the clamping rod 203a passes through the clamping hole 203b, it enters the inner cavity of the clamping block 203c, at this time the triangular block 203f is clamped in the clamping groove 203e on the surface of the clamping rod 203a under the action of the second spring 203h, realizing the fixation of the micro switch 202 and the mounting plate 201, at the same time, the butt joint rod 204a on the other side of the micro switch 202 is inserted into the butt joint hole 204b on the mounting plate 201, further ensuring the stability of the installation of the micro switch 202, and the mounting plate 201 is fixedly connected with the fixed plate 103 through two groups of symmetrically arranged mounting bolts 201a, so that the detection assembly 200 is stably installed on the main assembly 100.

[0053] When it is necessary to disassemble the micro switch 202, the pull ring 203g is pulled, the pull ring 203g drives the triangular block 203f to exit from the clamping groove 203e, and the fixation of the clamping rod 203a is released, at this time the first spring 203d-2 restores the deformation, pushes the ejection block 203d-1 abutting with the end of the clamping rod 203a, and the sliders 203d-3 on the top and bottom of the ejection block 203d-1 slide in the sliding grooves 203d-4 on the top and bottom of the inner cavity of the clamping block 203c, providing guidance and support for the movement of the ejection block 203d-1, so that the ejection block 203d-1 stably ejects the clamping rod 203a from the inner cavity of the clamping block 203c, thereby realizing the separation of the micro switch 202 and the mounting plate 201, after the pull ring 203g is loosened, the second spring 203h pushes the pull ring 203g and the triangular block 203f back to the initial position, facilitating the next installation.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and all should be covered in the scope of the claims of the present application.
