Through setting up first guide 45 and second guide 46, can guarantee that telescopic link 3 and inner skleeve 41 are vertical direction all the time at the slip direction, avoid telescopic link 3 to collide inner skleeve 41 because of the displacement of horizontal direction to can reduce because of probably producing the wearing and tearing that collide or friction cause between telescopic link 3 and the inner skleeve 41, prolong steering control device's life.

In some embodiments, the top end of the inner sleeve 41 may be formed with a first step hole, an upper step of the first step hole matches with the first guiding element 45, the first guiding element 45 is sleeved outside the telescopic rod 3 and is disposed inside the upper step of the first step hole, and the first guiding element 45 is slidably connected with the telescopic rod 3.

Under this condition, because the through-hole that the telescopic link 3 stretched into is still seted up in support 2 bottom, and first guide 45 need block in going up the ladder and just can play the guide effect, consequently, the diameter of through-hole can be greater than this first guide 45's internal diameter and be less than this first guide 45's external diameter on this support 2, just so can avoid first guide 45 to slide into support 2 inside from the through-hole, with the tight card of first guide 45 in the last ladder in first ladder hole, guaranteed the normal operating of first guide 45 guide function.

Through placing first guide 45 between telescopic link 3 and inner skleeve 41 for the gap between telescopic link 3 and the inner skleeve 41 is filled by first guide 45, and first guide 45 also constitutes the vice connection of sliding with telescopic link 3, thereby when telescopic link 3 and inner skleeve 41 produced relative slip, because first guide 45 has filled up the gap, just also avoided telescopic link 3 to rock about inside the inner skleeve 41, the degree of wear of telescopic link 3 and inner skleeve 41 has significantly reduced.

In some embodiments, the top end of the outer sleeve 42 may be formed with a second stepped hole, the upper step of the second stepped hole matches with the second guiding element 46, the second guiding element 46 is sleeved outside the inner sleeve 41 and is disposed inside the upper step of the second stepped hole, and the second guiding element 46 is slidably connected with the inner sleeve 41.

In addition, since the top end of the outer sleeve 42 is pressed by the sleeve end cap 43, it is ensured that the second guide 46 is also pressed in the second stepped hole by the sleeve end cap 43, and the second guide 46 is prevented from leaking out of the outer sleeve 42.

By placing the second guide 46 between the inner sleeve 41 and the outer sleeve 42, the gap between the inner sleeve 41 and the outer sleeve 42 is filled with the second guide 46, and the second guide 46 and the inner sleeve 41 also form a sliding pair connection, so that when the inner sleeve 41 and the outer sleeve 42 slide relatively, because the second guide 46 fills the gap, the left-right shaking of the inner sleeve 41 inside the outer sleeve 42 is avoided, and the wear degree of the inner sleeve 41 and the outer sleeve 42 is greatly reduced.

Fig. 4 is a partial enlarged view of a steering control device provided in an embodiment of the present application, and please refer to fig. 4, which shows a partial enlarged view of a portion outlined by a lower circle in fig. 1, so as to more clearly show a positional relationship between each component in the sleeve assembly 4 and the telescopic rod 3, and it can be seen that the following components can be arranged in order from inside to outside: the telescopic rod 3, the first guide 45, the inner sleeve 41, the second guide 46 and the outer sleeve 42, in other words, the size relationship of these five parts can be arranged from small to large to obtain the same sequence, which is not described herein.

In some embodiments, the first guide 45 and the second guide 46 may not be provided, so that the structure of the steering control device can be simplified.

In a possible implementation manner, in the steering control device, each component may be fixedly connected by a bolt, and of course, a pin connection, a rivet connection, a joggle connection, a welding connection, and the like may also be used.

All the above optional technical solutions may be combined arbitrarily to form the optional embodiments of the present disclosure, and are not described herein again.

Fig. 5 is a folding schematic view of a steering control device provided in an embodiment of the present application, and referring to fig. 5, taking the number of at least one handle bar 1 as 2 as an example, a foldable telescopic handle can be provided, when the telescopic rod 3 slides upwards relative to the inner sleeve 41 in the sleeve assembly 4, the telescopic rod seat 21 in the bracket 2 can be pushed to move upwards, so as to drive the two connecting rods connected with the telescopic rod seat 21 to move in the vertical direction, and the two connecting rods respectively drive the two handle bars to move in the vertical direction towards the direction close to the bracket 2, so as to be contracted from the horizontal position to the vertical position, thereby providing folding and telescopic functions, greatly improving the structural compactness of the handle, and improving the space utilization rate of the handle.

Fig. 6 is a schematic view of a relaxation of a steering control device according to an embodiment of the present application, and referring to fig. 6, on the basis of the foldable telescopic handle shown in fig. 5, a configuration when the handle is relaxed is shown, when the telescopic rod 3 slides downward relative to the inner sleeve 41 in the sleeve assembly 4, the telescopic rod seat 21 in the bracket 2 can be pushed to move downward, so as to drive the two connecting rods connected with the telescopic rod seat 21 to move in the vertical direction, and the two connecting rods respectively drive the two handle rods to move in the vertical direction away from the bracket 2, so that the handle is horizontally placed from the vertical placement, thereby greatly improving the structural compactness of the handle and improving the space utilization rate of the handle.

The embodiment of the application provides a steering control device, relative slip through between telescopic link and the sleeve subassembly, can drive at least one barre and use one end as the axle center, the direction motion of being close to or keeping away from the support, make steering control device when carrying out tensile based on the telescopic link, drive at least one barre and fold towards the direction of being close to the support, on the contrary, when carrying out the shrink based on the telescopic link, drive at least one barre and expand towards the direction of keeping away from the support, thereby can promote steering control device's compact structure degree greatly, improve steering control device's space utilization.
