In different places in this specification, "in one embodiment" does not mean the same embodiment, nor is it an embodiment that is separate or alternative to other embodiments.

[0030] Embodiment 1

[0031] Reference Figure 1 and Figure 2 For the first embodiment of the present application, the embodiment provides an electrically adjusted steering column with double sensors detecting axial position, which comprises a steering assembly 100 and a quick-mount assembly 200.

[0033] Specifically, the steering assembly 100 includes a steering column 101, and the steering column 101 is sleeved with a column outer sleeve 103.

[0034] The axial adjustment motor 102 can provide a certain axial adjustment force to achieve the effect of axial driving.

[0035] Specifically, the quick mounting assembly 200 is arranged at the top of the column outer sleeve 103 and includes a splicing piece 201, the splicing piece 201 is fixed to the top of the column outer sleeve 103, the top of the splicing piece 201 is provided with a mounting piece 202, one side of the splicing piece 201 is provided with a transmission plug-in piece 203, one side of the transmission plug-in piece 203 is provided with a height adjusting piece 204, the transmission plug-in piece 203 is movably connected to one side of the splicing piece 201, and the height adjusting piece 204 is fixed to the surface of the splicing piece 201.

[0036] The splicing piece 201 and the mounting piece 202 are spliced and assembled with each other, so that the disassembly and assembly of the second sensor 202b can be quickly completed.

[0037] Embodiment 2

[0038] Reference Figures 2-7 As a second embodiment of the utility model, the embodiment is based on the previous embodiment.

[0039] Specifically, the splicing piece 201 includes a splicing mounting seat 201a fixed to the top of the column outer sleeve 103, the top of the splicing mounting seat 201a is provided with a top plug-in block 201c, and one side of the top plug-in block 201c is fixed with a transmission rod 201e.

[0040] The top plug-in block 201c can be buckled from top to bottom to achieve the effect of top buckling, thereby improving the stability of installation.

[0041] Specifically, one side of the splicing mounting seat 201a is fixed with a limiting cylinder 201d, and the transmission rod 201e is movably connected to the inner wall of the limiting cylinder 201d.

[0042] The limiting cylinder 201d can limit and guide the transmission rod 201e, so that the transmission rod 201e can be conveniently adjusted in height along with the mounting connecting plate 202a.

[0043] Specifically, the splicing piece 201 further comprises a telescopic block 201g fixed to the surface of the splicing mounting seat 201a, and a first extrusion block 201f is fixed to the top of the telescopic block 201g.

[0044] The telescopic block 201g has a telescopic function, and the height of the first extrusion block 201f can be adjusted through active adjustment.

[0045] Specifically, the mounting piece 202 comprises a mounting connecting plate 202a arranged at the top of the splicing mounting seat 201a, and a connecting block 202d is fixed to the surface of the mounting connecting plate 202a.

[0046] Specifically, the top of the mounting connecting plate 202a is fixed with a second sensor 202b.

[0047] The second sensor 202b can form redundancy with the built-in Hall sensor of the axial adjustment motor 102, and when the built-in sensor of the axial adjustment motor 102 fails, the second sensor 202b can accurately feed back the position of the steering column 101 to the upper controller, avoiding the failure of the axial position positioning of the steering column 101 and the safety hazard when the steering column 101 executes the intelligent cockpit function action.

[0048] Specifically, the inner wall of the moving seat 202f is movably connected with a sliding rod 202g, one side of the sliding rod 202g is fixed with a first transmission block 202h, and the other side of the sliding rod 202g is fixed with a second extrusion block 202e.

[0049] The second extrusion block 202e can be driven by the sliding rod 202g to displace the first transmission block 202h under the extrusion action of the first extrusion block 201f.

[0050] Specifically, the top of the column outer sleeve 103 is fixed with a first mounting seat 104, one side of the first mounting seat 104 is provided with a second mounting seat 105, and the second mounting seat 105 is fixed to one side of the column outer sleeve 103.

[0051] The first mounting seat 104 and the second mounting seat 105 can facilitate the fixation of the column outer sleeve 103

[0052] Specifically, the transmission plug-in piece 203 comprises a transmission sliding rod 203a slidably connected to the inner wall of the guide rail 201b, a second transmission block 203d is fixed to one side of the transmission sliding rod 203a, a fixed ring 203b is fixedly arranged on the surface of the transmission sliding rod 203a, a reset spring 203c is fixed to one side of the second transmission block 203d, a fixed plate 203e is arranged on the surface of the transmission sliding rod 203a, and the reset spring 203c is fixed to one side of the second transmission block 203d.

[0053] The reset spring 203c can generate elastic force by restoring deformation to drive the transmission slide rod 203a to automatically reset.

[0054] Specifically, the height adjusting member 204 includes a shell 204a fixed to the surface of the spliced mounting seat 201a, an inner wall of the shell 204a movably connected to a limiting movable plate 204c, the limiting movable plate 204c fixed to the bottom of the transmission rod 201e, one side of the transmission rod 201e provided with an arc-shaped insertion slot 204d matched with the transmission slide rod 203a, and the bottom of the limiting movable plate 204c fixed with a connecting spring 204b, the connecting spring 204b fixed to the inner wall of the shell 204a.

[0055] In use, when the built-in sensor of the axial adjustment motor 102 fails, the second sensor 202b can accurately feed back the position of the steering column 101 to the upper controller, avoiding the safety hazards of the failure of the axial position positioning of the steering column 101 and the overall execution of the intelligent cockpit function action.

[0056] When the second sensor 202b needs to be installed, the user first aligns the moving seat 202f with the guide rail 201b, and then pushes the moving seat 202f into the inner cavity of the guide rail 201b. When the spliced mounting seat 201a and the second sensor 202b are completely aligned, the user can push the first extrusion block 201f upward to extrude the second extrusion block 202e, so that the second extrusion block 202e drives the first transmission block 202h to extrude the second transmission block 203d through the sliding rod 202g. The second transmission block 203d extrudes the transmission rod 201e through the transmission slide rod 203a and is inserted into the arc-shaped insertion slot 204d, so as to drive the transmission rod 201e to move downward, thereby driving the top insertion block 201c to move downward and be inserted into the inner cavity of the insertion slot 202c to complete positioning.

[0057] When it needs to be disassembled, the user only needs to reverse the above operation. It should be noted that when the first extrusion block 201f no longer extrudes and limits the second extrusion block 202e, the reset spring 203c will generate elastic force by resetting to drive the second transmission block 203d to adjust the position through the transmission slide rod 203a, thereby canceling the limitation of the transmission slide rod 203a on the transmission rod 201e. The transmission rod 201e is driven by the elastic force generated by the deformation of the shell 204a to drive the top insertion block 201c to fall off from the inner cavity of the insertion slot 202c, thereby canceling the limitation.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. 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 they should be covered in the scope of the claims of the present application.
