Detailed Description
The mechanical steering column with the locking function comprises an upper column assembly 1, a lower column 2, a supporting seat 3, a locking mechanism and a pressing seat 5 (see the accompanying drawings 1 and 2 in the specification).
A lower pipe column 2 is slidably arranged in one end of the upper pipe column assembly 1; the lower part of the upper pipe column assembly 1 is provided with a supporting seat 3.
The supporting seat 3 comprises a connecting bottom plate 6 and an elastic vertical plate 7; elastic vertical plates 7 are symmetrically arranged at the lower ends of the connecting bottom plates 6; the elastic riser 7 is provided with a vertical chute 8 (see fig. 1 and 7 of the description).
The upper string assembly 1, lower string 2 and support base 3 are of conventional design in the art. The structure of the supporting seat 3 is consistent with that of the supporting seat in the patent of the patent with the publication number CN 214493064U.
The outer portion of the lower end of the upper pipe column assembly 1 is provided with an expansion joint 4 (see figure 4 of the specification) which is in an I-shaped mechanism. The upper pipe column assembly 1 on two sides of the expansion joint 4 is fixedly provided with a compression seat 5 (see figure 3 of the specification). The pressing seat 5 is provided with a transverse chute 9 (see fig. 3 of the specification).
The aim of setting the expansion joint 4 and the compression seat 5 is that: so that the upper pipe column assembly 1 has the capability of elastic deformation under the action of the expansion joint 4; so when compressing tightly seat 5 draw close each other under the effect of external force, it can drive the interior shrink of last tubular column assembly 1 and press from both sides tight fixed with tubular column 2 down, so can reach and fix tubular column 2 down directly through last tubular column assembly 1 to the very easy problem that takes place slight rocking between current last tubular column assembly and the tubular column down.
When the external force applied to the compression seat 5 disappears, the upper pipe column assembly 1 is reset under the action of self-elastic force, and after the upper pipe column assembly 1 is reset, the lower pipe column 2 is loosened, so that the purpose of adjusting the relative position between the lower pipe column 2 and the upper pipe column assembly 1 can be achieved.
The elastic vertical plate 7 of the supporting seat 3 extends downwards to the side surface of the compressing seat 5; the elastic riser 7 is connected to the compression seat 5 by a locking mechanism (see fig. 2 and 6 of the description).
The locking mechanism includes a connecting rod 10, a locking cam a14, a locking cam B13, and an adjustment handle 15 (see fig. 6, 7, and 8 of the specification).
A connecting pull rod 10 is arranged in the compression seat 5; the two ends of the connecting pull rod 10 respectively pass through the transverse chute 9 of the compression seat 5 and the vertical chute 8 of the supporting seat 3 and then extend to the outer side of the supporting seat 3; one end of the connecting pull rod 10 is provided with a flat pad 12 through an assembling nut 11; the flat pad 12 is in abutting connection with the elastic vertical plate 7; a locking cam B13 and a locking cam A14 are sequentially arranged at the other end of the connecting pull rod 10; the locking cam A14 is in abutting connection with the locking cam B13; the locking cam a14 is provided with an adjusting handle 15 (see fig. 6 and 7 of the specification).
The locking cam B13 is connected with the elastic vertical plate 7 in a clamping way; the locking cam B13 cannot rotate under the action of the elastic riser 7.
The outer side surface of the locking cam A14 is provided with an adjusting handle 15 through a rectangular boss 16; the inner side surface of the locking cam A14 is provided with a plurality of control sliding teeth 17 in a ring shape; a control chute 18 is arranged on the side surface of the locking cam B13 corresponding to the control sliding tooth 17; the bottom surface of the control chute 18 is in a beveled structure (see fig. 8 of the specification).
The purpose of setting the locking mechanism in this way is that: when the locking cam A14 is operated, the locking cam A14 can be driven to rotate by the adjusting handle 15, and the control sliding groove 18 of the locking cam B13 can be extruded by the control sliding tooth 17 in the rotating process of the locking cam A14; after being pressed, the locking cam B13 extrudes the pressing seat 5 from two ends under the cooperation of the connecting pull rod 10 and the assembling nut 11, so that the purpose that the lower pipe column 2 is clamped and fixed by extruding the upper pipe column assembly 1 through the pressing seat 5 is achieved.
When the adjusting handle 15 drives the locking cam A14 to reversely rotate, the control sliding teeth 17 on the locking cam A14 are connected along the control sliding groove 18 towards the bottom end of the control sliding teeth, and the compaction seat 5 automatically resets the upper pipe column assembly 1; thus, the purpose of adjusting the relative positions of the upper pipe column assembly 1 and the lower pipe column 2 can be achieved. After the upper pipe column assembly 1 and the lower pipe column 2 are adjusted to proper positions, the upper pipe column assembly 1 and the lower pipe column 2 are locked through the adjusting handle 15.
The mechanical steering column with the locking function is compact in structure and ingenious in design, and when the mechanical steering column is in operation, the locking mechanism can squeeze the upper column assembly 1 through the compression seat 5 to deform the upper column assembly, so that the purpose of directly clamping and fixing the lower column 2 inside the mechanical steering column is achieved, the problem that the upper column assembly 1 and the lower column 2 stored in the existing mechanical steering column are easy to slightly shake is solved, and the mechanical steering column is particularly suitable for the use requirement of an automobile steering system.
