In the case that the external force that handle 30 is subject to is less than or equal to predetermined value, handle 30 can drive 21 turns of regulating mechanism by middleware 40
It moves to realize tubing string mechanism 10, in the case where the external force that handle 30 is subject to is greater than predetermined value, handle 30 can be relative to tune
Mechanism 21 is saved to rotate.
The technical solution of Application Example one is colliding, and driver hits the power on handle 30 greater than predetermined value (one
As 70N or more) in the case where, handle 30 can be rotated relative to regulating mechanism 21, with reduce collision when handle 30 to driver
The injury of knee.
It should be noted that above-mentioned angle refers to the angle between tubing string mechanism 10 and horizontal plane.
As shown in Figures 3 to 5, in example 1, middleware 40 is annular in shape, is provided on middleware 40 towards handle 30
The first protrusion 41 and the second protrusion 42 towards regulating mechanism 21.It can be controlled by the first protrusion 41 of setting and the second protrusion 42
Handle 30 processed required frictional force overcome when being rotated relative to regulating mechanism 21.
In order to increase the required frictional force overcome when handle 30 is rotated relative to regulating mechanism 21, such as Fig. 3 to Fig. 5 institute
Show, in example 1, the first protrusion 41 and the second protrusion 42 is provided on middleware 40, the first protrusion 41 and/or second is convex
It is multiple for playing 42.The number of the number of specific first protrusion 41 and the second protrusion 42 may be set according to actual conditions.At other
In embodiment, the change of frictional force can be realized by changing the size of the first protrusion 41 and the second protrusion 42.
As shown in Figures 3 to 5, in example 1, the first protrusion 41 is multiple, the second protrusion 42 be it is multiple, first is convex
41 are played to be alternately arranged with the second protrusion 42.Above structure make handle 30 stress point and regulating mechanism 21 stress point more
Uniformly, guarantee the service life of handle 30 and regulating mechanism 21.In addition, be alternately arranged can also for the first protrusion 41 and the second protrusion 42
The intensity for effectively increasing middleware 40, preventing middleware 40, deformation occurs.
As shown in Figures 3 to 5, in example 1, the first protrusion 41 and the second protrusion 42 are provided on middleware 40, the
One protrusion 41 and/or the second protrusion 42 are by being stamped and formed out.Above structure is simple, easy to process, and at low cost.
As shown in figure 5, in example 1, middleware 40 is the split ring with opening 43.Above structure is simple, is convenient for
Installation personnel installation.
As shown in Figures 2 and 3, in example 1, regulating mechanism 21 including output shaft 211 and is set to output shaft
The cam 212 of 211 ends, is provided with mounting hole 31 on handle 30, partial cam 212 protrude into mounting hole 31 and with mounting hole 31
Inner wall between formed installation space 1, middleware 40 be pressed into installation space 1.Above structure is simple, is easily assembled.Furthermore, it is necessary to
Illustrate, changing the required frictional force overcome when handle 30 is rotated relative to regulating mechanism 21 can also be installed by changing
The inner wall in hole 31 is realized with the distance between the outer wall of part of cam 212 protruded into mounting hole 31.It is above-mentioned apart from smaller, make
The power obtained in the indentation installation space 1 of middleware 40 is bigger, and the frictional force that rotation needs to overcome is also bigger.Above-mentioned distance is bigger,
So that the power that middleware 40 is pressed into installation space 1 is smaller, the frictional force that rotation needs to overcome is also just smaller.
As shown in Figures 2 and 3, in example 1, cam 212 includes main cam 2121 and cooperates with main cam 2121
Sub- cam 2122, handle 30 is same by middleware 40 with main cam 2121 by the power for being less than predefined size
Step rotates, and has spikes/low- points on sub- cam 2122, passes through output when main cam 2121 and sub- cam 2122 are nearly stuck
The frictional force of shaft flange disk drives output shaft 211 to rotate.Sub- cam 2122 is fixed, when main cam 2121 is rotated with handle 30
When, when the high point of main cam 2121 corresponds to sub- 2122 high point of cam, axial locked, tubing string be cannot be adjusted, when main cam 2121
Axial to unclamp when high point corresponds to sub- 2122 low spot of cam, tubing string is adjustable.
As shown in figure 3, in example 1, cam 212 (main cam 2121) include first segment 213 interconnected and
Second segment 214, first segment 213 protrude into mounting hole 31 and form installation space 1, second segment between the inner wall of mounting hole 31
214 have lug boss, and the outer surface of lug boss can be abutted with handle.Above structure is simple, easy to process and assembly.It needs
Bright, in the present embodiment, main cam 2121 includes first segment 213 interconnected and second segment 214.
It should be noted that in example 1, when tubing string mechanism 10 and the manufacture of handle 30 are assembled, handle 30 and cam
212 are pressed the assembly of middleware 40 therebetween by interference, pass through magnitude of interference and the first protrusion 41 and the second protrusion 42
Quantity, the frictional force that the grid surface of convex surfaces generates make handle 30 not influence normal regulatory function in normal regulating, when
When driver's knee is contacted with handle 30 when colliding, when pressure is greater than the frictional force of middleware 40, handle 30 can be opposite
Cam 212 rotates, and reduces the injury generated by knee and 30 hard collision of handle.
The difference of the tubing string regulating mechanism of the tubing string regulating mechanism and embodiment one of embodiment two is the first protrusion and the
The molding mode of two protrusions.Specifically, in example 2, the first protrusion and the second protrusion are provided on middleware, first is convex
It rises and/or second projects through and be bent to form.Above-mentioned molding mode is simple, easy to process.
Present invention also provides a kind of steering systems, according to the embodiment packet of the steering system (not shown) of the application
