In the present embodiment, as Figure 2-3, steering column collision system, including outer tube 1 and inner sleeve 2, inner sleeve 2
Be inserted into outer tube 1, the outer surface of inner sleeve 2 contacts with the inner surface of outer tube 1 and can produce frictional force, inner sleeve 2 with
Being provided between outer tube 1 is used to increase the friction plate 3 of frictional force.
Specifically, as shown in figure 3, outer tube 1 is hollow strip outer tube, inner sleeve 2 is also outside the circle of strip
Sleeve pipe.When outer tube 1 is installed with inner sleeve 2, inner sleeve 2 is inserted into the cavity of outer tube 1.After installation, the appearance of inner sleeve 2
It is in close contact between the inner surface of face and outer tube 1.Relative slip is produced during collision, between post outer tube 1 and inner sleeve 2, it is interior
Frictional force can be produced between the outer surface of sleeve pipe 2 and the inner surface of outer tube 1.Because friction plate 3 adds outer tube 1 and inner sleeve
Frictional force between pipe 2, collision peak force will be higher, disclosure satisfy that requirement.
In the present embodiment, friction plate 3 it is simple in construction relative to positive locking system of the prior art, and easily pacify
Dress, occupies little space.
Further, as shown in figure 3, offering slot 11 on the inner surface of outer tube 1, in the insertion slot 11 of friction plate 3.
After friction plate 3 is arranged in slot 11, the inner surface of friction plate 3 is concordant with the inner surface of outer tube 1, outer tube 1
Inner surface still keep being in close contact with the outer surface of inner sleeve 2.
Alternatively it is also possible to offer slot on the outer surface of inner sleeve 2, friction plate is arranged in slot.Now, rub
The outer surface of pad and the flush with outer surface of inner sleeve 2 so that the outer surface of inner sleeve 2 is still protected with the inner surface of outer tube 1
Hold close contact.
Alternatively, friction plate 3 and slot 11 be cementing or mode connects for screw, or the press-in slot of friction plate 3 in.
Further, as shown in figure 4, friction plate 3 includes the particulate matter 32 of substrate 31 and laying on the substrate 31, substrate 31
It is connected with slot 11, particulate matter 32 is contacted with the outer surface of inner sleeve 2.
Substrate 31 is the substrate of friction plate 3, and tiny particulate matter 32 is laid on the surface of substrate 31.In the present embodiment,

The outer surface of inner sleeve 2 is simultaneously contacted.
Due to being equipped with particulate matter 32 on substrate 31, by increasing capacitance it is possible to increase the friction system of friction plate 3, increasing friction force is played
Effect, final increase collision peak force.
Alternatively, when slot 11 is opened in the outer surface of plunger 2, particulate matter 32 is contacted with the inner surface of outer tube 1.This
When, particulate matter 32 is laid on the outer surface of substrate 31, and the inner surface of substrate 31 is connected with slot 11, the outer surface court of substrate 31
To outer tube 1 inner surface and contact.
In the present embodiment, coefficient of friction is 0.4~0.6 between the outer surface of friction plate 3 and inner sleeve 2.
Alternatively, when friction plate 3 is arranged on the outer surface of inner sleeve 2, between the inner surface of friction plate 3 and outer tube 1
Coefficient of friction be 0.4~0.6.
In the present embodiment, the hardness of friction plate 3 is HRB50.The hardness class of the same cold-rolled steel of hardness (DC04) of friction plate 3
Seemingly.Friction plate 3 has certain hardness, it can be ensured that when outer tube 1 is slided relatively with inner sleeve 2, friction plate 3 will not be damaged
Peel off.
Further, as shown in figure 3, friction plate 3 there are four, and arranged along the circumferencial direction uniform intervals of outer tube 1.
Alternatively, friction plate 3 can also be whole piece, or two and more than.As long as increase outer tube 1 and post can be played
The effect of frictional force between plug 2, belongs to protection domain of the present utility model.
In the present embodiment, as shown in figure 5, in Fig. 54 be clamping system regulation handle.
When handle 4 is opened, there is gap between outer tube 1 and inner sleeve 2, inner sleeve 2 can be moved, this is adjustment
Function.
