The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
In addition, the technical features of the different embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.
Referring to fig. 1 and 2, there is shown a specific embodiment of a steering column and a pretensioning adjustment assembly according to the present utility model, the steering column includes an upper column tube 10 and a lower column tube 20 that are slidably connected, wherein an upper end portion of the lower column tube 20 is sleeved on a lower end portion of the upper column tube 10, an upper end portion of the lower column tube 20 is provided with at least one adjustment hole 21, a region where the lower column tube 20 is matched with the upper column tube 10 (i.e., a portion of the region where the lower column tube and the upper column tube are slidably connected) is provided with a pretensioning adjustment assembly 30, the pretensioning adjustment assembly 30 includes an adjustment gasket 31, a pretensioning spring piece 32, and a fastening piece 33 penetrating the pretensioning spring piece 32 and the adjustment gasket 31, wherein the adjustment gasket 31 is located at the adjustment hole 21 of the lower column tube 20, an inner side surface of the adjustment gasket 31 is an arc surface matched with an outer surface of the upper column tube 10, and the pretensioning spring piece 32 abuts against an outer side surface of the adjustment gasket 31 so that an elastic force acts on the adjustment gasket 31; the fastening member 33 detachably connects the pre-tightening spring plate 32 and the adjusting washer 31 to the lower column tube 20.
The steering column realizes pretightening force adjustment between the upper column pipe 10 and the lower column pipe 20 by arranging the pretightening force adjustment assembly 30. In the pre-tightening adjusting assembly 30, the pre-tightening elastic piece 32 is abutted against the adjusting gasket 31, so that the elastic force of the pre-tightening elastic piece 32 acts on the upper column 10 in a manner that the inner side surface of the adjusting gasket 31 acts on the wall of the upper column 10, and the upper column 10 can slide along the inner wall surface of the lower column 20 with a preset sliding force. Because the adjusting gasket 31 and the pre-tightening spring piece 32 can be detachably connected with the lower column tube 20 by the fastener 33, when the lower column tube 20 is used, different pre-tightening force adjustment between the upper column tube 20 and the lower column tube 20 can be realized by selecting the pre-tightening spring pieces 32 with different elastic coefficients (for example, pre-tightening spring pieces 32 with different thicknesses or pre-tightening spring pieces 32 with different elastic materials). And the pretension adjusting assembly 30 has simple structure and lower manufacturing and assembly cost. During assembly, the adjusting gasket 31 and the pre-tightening elastic piece 32 are sequentially placed on the lower column tube 20, the adjusting gasket 31 and the pre-tightening elastic piece 32 are connected to the lower column tube 20 through the fastener 33, the assembly and disassembly processes are simple, and different pre-tightening elastic pieces 32 or adjusting gaskets 31 can be conveniently replaced to adjust different pre-tightening forces.
Specifically, the adjusting pad 31 is made of plastic or polymer material, so as to avoid friction scratch on the outer surface of the upper column tube 10 when the upper column tube 10 made of metal slides. As shown in fig. 4 and 5, the two sides of the pre-tightening spring plate 32 and the adjusting washer 31 are respectively provided with a connecting hole 321/311, the wall of the lower column tube 20 is provided with a threaded hole 22 matched with the connecting hole, and the fastening piece 33 is a fastening bolt penetrating through the connecting hole 321/311 of the pre-tightening spring plate 32 and the adjusting washer 31 and the threaded hole 22 of the lower column tube 20.
Specifically, the matching structure of the pre-tightening spring plate 32 and the adjusting gasket 31 is not unique; in an alternative embodiment, the pre-tightening spring 32 is an arc spring protruding toward the adjusting washer 31, and the adjusting washer 31 has a smooth upper surface structure, so that the pre-tightening spring 32 directly acts on the upper surface of the adjusting washer 31. In another alternative embodiment, as shown in fig. 2 and fig. 4, at least one adjusting rib 312 is disposed on an outer side surface of the adjusting spacer 31, the pre-tightening spring plate 32 is abutted against the adjusting rib 312, and the acting position of the pre-tightening spring plate 32 and the adjusting spacer 31 can be adjusted in a manner that the adjusting spacer 31 is provided with the adjusting rib 312, so as to further improve the adjusting stability.
More specifically, the outer side surface of the adjusting spacer 31 is provided with two adjusting ribs 312 extending along the axial direction of the upper column tube 10 and the lower column tube 20, and the two adjusting ribs 312 are symmetrically disposed at two sides of the axial line. Since the adjusting ribs 312 are symmetrically disposed at both sides of the axis of the upper column tube 10 and the lower column tube 20, the positions of the adjusting gaskets 31 acting on the upper column tube 10 are more symmetrical, and uneven local stress is avoided. The adjusting ribs 312 with different thicknesses or different widths are arranged on the adjusting gasket 31 to match with the same pre-tightening spring piece 32, so that the pre-tightening force between the upper column tube 10 and the lower column tube 20 can be adjusted.
Specifically, in order to reduce the friction force between the adjusting pad 31 and the upper pillar 10 so that the upper pillar 10 can reliably slide along the inner pipe wall of the lower pillar 20, the inner side surface of the adjusting pad 31 is provided with a plurality of protruding or recessed structures 313, and the contact area between the adjusting pad 31 and the upper pillar 10 is smaller than the area of the adjusting pad 31 covered on the upper pillar 10 due to the contact between the upper pillar 10 and the upper surface of the protruding or recessed structures 313 of the adjusting pad 31, so that the friction force between the adjusting pad 31 and the upper pillar 10 is moderate, thereby avoiding the noise problem caused by unsmooth sliding of the upper pillar 10 in the area.
Specifically, as shown in fig. 4, the arcuate surface of the adjusting pad 31 has a plurality of raised or recessed structures 313 forming a grid-shaped cavity for accommodating a lubricating medium, so that the friction between the adjusting pad 31 and the upper column tube 10 can be further reduced.
Specifically, in an alternative embodiment, as shown in fig. 4, the adjusting pad 31 is formed to be higher than the boss 314 on the surface of the other area in the area where the fastening member 33 is engaged, and the boss 314 is provided with the connection hole 311 penetrating the fastening member 33. More specifically, the boss 314 is formed into a circular boss 314, and when assembled, the lower surface of the circular boss 314 is attached to the mounting plane of the lower column tube 20, and the fastener 33 is fastened to the lower column tube 20, the compression deformation of the boss 314 provides a bolt compression stroke, and at the same time, the compression deformation of the boss 314 can also play a role in eliminating a gap.
As shown in fig. 4, the outer surface of the adjusting rib 312 is higher than the outer surface of the boss 314, the pre-tightening spring 32 is formed into a spring form with a flat plate in an initial state, and when the pre-tightening spring is mounted on the lower column tube 20 through a fastening bolt, the pre-tightening spring is elastically deformed under the action of the adjusting rib 312 with the outer surface higher than the boss 314 and acts on the adjusting rib 312 area of the adjusting gasket 31, so that the adjusting gasket 31 compresses the outer tube wall of the upper column tube 10.
Because the area where the lower pillar 20 and the upper pillar 10 are matched is longer, in an alternative embodiment, as shown in fig. 1 and 3, two groups of pre-tightening adjusting assemblies 30 are disposed on the area where the lower pillar 20 and the upper pillar 10 are matched, two groups of pre-tightening adjusting assemblies 30 are disposed at intervals on two sides of the area where the lower pillar 20 and the upper pillar 10 are matched, and the two groups of pre-tightening adjusting assemblies 30 are located at the same circumferential position of the lower pillar 20, so as to keep the friction force between the upper pillar 10 and the lower pillar 20 stable, and improve the natural frequency and rigidity. The lower column tube 20 has reinforcing ribs 23 in the region between the adjacent two sets of the pretensioning adjustment assemblies 30 to increase the rigidity of the lower column tube 20.
The present utility model also provides a specific implementation manner of a vehicle, and the steering column structure of the vehicle adopts the steering column structure of the above embodiment, which is not described herein again.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While obvious variations or modifications are contemplated as falling within the scope of the present utility model.
