Fig. 1 is the embodiment of the utility model provides an in the structural schematic diagram of locking elastic component, fig. 2 is the embodiment of the utility model provides an in the structural schematic diagram of guide bracket, fig. 3 is the embodiment of the utility model provides an in the embodiment of locking elastic component and guide bracket complex structural schematic diagram. Please refer to fig. 1 to 3, an embodiment of the present invention provides a steering column height adjustment locking mechanism, which includes a locking elastic member 10 and a guiding bracket 11, wherein two sides of the locking elastic member 10 are provided with a pressing block 101, and the guiding bracket 11 is provided with a locking groove 112 matched with the pressing block 101. In this embodiment, the locking elastic member 10 is, for example, a locking spring, the locking groove 112 may be rectangular, and the pressing block 101 may be serrated.

Fig. 4 is the embodiment of the utility model provides an in the embodiment of the front elevation view of steering column height control locking mechanism, fig. 5 is the embodiment of the utility model in the embodiment of the side view of steering column height control locking mechanism. Referring to fig. 4 and 5, the steering column height adjustment locking mechanism further includes a coil spring 12, an outer cam mechanism 13, a handle bolt 14, an adjustment handle 15, an inner cam mechanism 16, and a swing bracket 17, wherein the locking elastic member 10 passes through the inner cam mechanism 16 through a middle circular hole and upper and lower special-shaped holes and is fixed to the inner cam mechanism 16, the outer cam mechanism 13 and the adjustment handle 15 are fixed to the handle bolt 14 through riveting, the handle bolt 14 passes through the adjustment handle 15, the outer cam mechanism 13, the inner cam mechanism 16, the locking elastic member 10, a guide groove 111 of the guide bracket 11, the coil spring 12, and the swing bracket 17, and a boss 161 of the inner cam mechanism 16 passes through the guide groove 111 and is embedded in the swing bracket 17, so that the inner cam mechanism 16 cannot rotate.

Referring to fig. 1 to 5, locking grooves 112 are disposed on the left and right sides of the guide groove 111, the locking grooves 112 have slide ways 113, and the toothed pressing blocks 101 on the locking elastic member 10 slide into the locking grooves 112 through the slide ways 113, so that the locking grooves 112 on the guide bracket 11 and the pressing blocks 101 on the locking elastic member 10 are in concave-convex fit to form a robust locking device.

The working principle of the steering column height adjusting and locking mechanism provided by the embodiment is as follows: the guide bracket 11 is fixed, when the adjusting handle 15 is opened, the adjusting handle 15 rotates at an angle along with the outer cam mechanism 13, at this time, the coil spring 12 compressed by the inner cam mechanism 16 and the swing bracket 17 pushes the inner cam mechanism 16 to move axially towards the outer cam mechanism 13 by virtue of the tension of the coil spring 12, the inner cam mechanism 16 further drives the locking elastic piece 10 to be away from the guide bracket 11, at this time, when the height is adjusted, the swing bracket 17 drives the handle bolt 14, the coil spring 12, the locking elastic piece 10, the inner cam mechanism 16, the outer cam mechanism 13 and the adjusting handle 15 to slide up and down along the guide groove 111, so that the steering wheel is adjusted to any position suitable for a driver. When the adjusting handle 15 is closed, the outer cam mechanism 13 presses the inner cam mechanism 16 and the locking elastic member 10 toward the guide bracket 11, so that the locking groove 112 on the guide bracket 11 is in concave-convex fit with the pressing block 101 on the locking elastic member 10.

Even if the pressing block 101 is not in the locking groove 112, the elastic deformation of the locking elastic part 10 has little influence on the closing force of the adjusting handle 15, so that the steering column still can maintain effective holding force, when collision and collapse occur, the pressing block 101 can move along the slide way 113 to slightly displace and slide into the locking groove 112, and further the steering column can still be effectively locked in the collision process, the steering column is guaranteed to stably collapse, and finally the safety of a driver is effectively protected.

The utility model provides a steering column height adjustment locking mechanism optimizes locking elastic component 10 and guide bracket 11 structure, simple structure, easy shaping, through cooperating compact heap 101 and guide bracket 11's locking groove 112 of locking elastic component 10, makes locking elastic component 10 can reciprocate along guide bracket 11, thus can carry out height adjustment; in addition, the stability of the height direction can be effectively kept in the collision collapse process, the smooth collapse of the steering column is ensured, and the aim of effectively protecting a driver is fulfilled.
