Detailed description of the invention
Detailed description of the invention of the present utility model is further illustrated below in conjunction with accompanying drawing。
As shown in Figure 1-2, the collision energy-absorbing assembly of steering column, including upper bracket 1 and piston shoes 2, upper bracket is provided with U-type groove 11, and piston shoes 2 are inserted in U-type groove 11, and collision energy-absorbing assembly also includes connecting pin 3, upper bracket 1 offers the first connecting hole 12, offering the second connecting hole 21 on piston shoes 2, connecting pin 3 is inserted in the first connecting hole 12 and the second connecting hole 21, and with the first connecting hole 12 and the second connecting hole 21 interference fit。
During installation, piston shoes 2 are inserted in the U-type groove 11 of upper bracket 1, first connecting hole 12 is directed at the second connecting hole 21, then connecting pin 3 is inserted in the first connecting hole 12 and the second connecting hole 21, and with the first connecting hole 12 and the second connecting hole 21 interference fit。Piston shoes 2 are connected with CCB (not shown) through installing hole 24 (referring to Fig. 5-6) by bolt, and CCB is the primary load-carrying members of steering。
When collision energy-absorbing assembly is collided power, it is connected owing to piston shoes 2 are fixing with CCB。Piston shoes 2 maintain static, and when impact force exceedes the crumple power of collision energy-absorbing assembly, upper bracket 1 is knocking-on, and now connecting pin 3 ruptures。As it is shown on figure 3, upper bracket 1 separates with piston shoes 2, connecting pin 3 part for fracture is stayed in the first connecting hole 12 of upper bracket 1, and another part is stayed in the second connecting hole 21 of piston shoes 2。
Owing to piston shoes 2 realize closely cooperating by connecting pin 3 with upper bracket 1, when collision energy-absorbing assembly is collided power, connecting pin 3 ruptures, the crumple power of collision energy-absorbing assembly is determined by size and the material properties of connecting pin 3, such as: diameter, intensity etc., decrease the influence factor of crumple power, are beneficial to the control of crumple power size。
Preferably, piston shoes 2 and upper bracket 1 matched in clearance。Piston shoes 2 no longer deform, and crumple power is not affected by the material of piston shoes 2。Crumple power does not consider further that the impact of riveting parameter yet。
In the present embodiment, as Figure 1-3, piston shoes 2 have two, are separately mounted to the both sides of upper bracket 1。
In the present embodiment, as Figure 1-3, the connecting pin 3 of corresponding each piston shoes 2 has two。
It is preferred that the number of the connecting pin 3 of corresponding each piston shoes 2 can also be two pairs, or more。
In the present embodiment, as seen in figs. 5-6, piston shoes 2 include rectangular body 22 and the slot 23 being arranged on 22 3 limits of rectangular body, slot 23 is inserted on three sides of U-type groove 11, on first connecting hole 12, two sides that to be opened in U-type groove 11 relative, the second connecting hole 21 is opened on slot 23 and is directed at the first connecting hole 12。
Wherein, as Figure 2-3, U-type groove 11 includes three sides and a breach altogether, and breach inserts for piston shoes 2。On three sides of the rectangular body 22 of piston shoes 2, correspondence offers slot 23。The width of U-type groove 11 is less than the width of piston shoes 2, and in Fig. 5, the width of piston shoes 2 is horizontal direction。Therefore, piston shoes 2 are inserted in U-type groove 11。After insertion, the side of U-type groove 11 enters in slot 23。As seen in figs. 5-6, on the second connecting hole 21 two sides that to be opened on slot 23 relative, it is respectively arranged with one。
It is preferred that the three of U-type groove 11 sides all can offer the first connecting hole 12, three sides corresponding with the slot 23 of piston shoes 2 also all offer the second connecting hole 21。
Preferably, on slot 23 two limits that can also to be arranged in rectangular body 22 relative, only relative with in U-type groove 11 dual-side of slot 23 connects, and on the first connecting hole 12 two sides that can only to be opened in U-type groove 11 relative, the second connecting hole 21 and the first connecting hole 12 are correspondingly arranged。
It is preferred that the first connecting hole 12 and the second connecting hole 21 on every side can also be two or more。
Preferably, connecting pin 3 is made up of plastics combined fiberglass, and the hardness of this material is relatively big, poor toughness, it is easy to fracture。
It is preferred that connecting pin 3 can also by rigid plastics, or aluminium alloy is made。
Above-described is only principle of the present utility model and preferred embodiment。It should be pointed out that, for the person of ordinary skill of the art, on the basis of this utility model principle, it is also possible to make other modification some, also should be regarded as protection domain of the present utility model。
