Detailed Description
The adjusting and limiting assembly of the automobile steering column consists of a control cam 3, a lock nut 4, a return spring 5, a limiting pin 6, an extrusion container 7 and a limiting sleeve 8 (see the attached figure 1 in the specification).
A limiting sleeve 8 (see the attached figure 3 of the specification) is fixedly arranged on the shell 2 through a locking nut 4; the circumferential surface of the limiting sleeve 8 is provided with external threads; the limiting sleeve 8 is arranged on the shell 2 through an external thread; the inner hole surface of the position-limiting sleeve 8 is in a step-shaped structure (refer to the attached figure 3 in the specification).
The fine hole part of the limiting sleeve 8 is provided with an extrusion container 7 in a sliding way through a guide chute (not shown in the attached drawing of the specification); the upper end of the extrusion container 7 is in a circular arc structure.
The upper end of the extrusion container 7 extends to the outer end of the limiting sleeve 8 and then is connected with the control cam 3 arranged on the shell 2 in a sliding way. Because the control cam 3 and the extrusion container 7 are in sliding connection, the upper end of the extrusion container 7 is designed into an arc structure for the purpose: so as to avoid the problem of 'wear and seizure' between the control cam 3 and the extrusion container 7 when the extrusion container 7 is in other states.
The control cam 3 is connected with a control handle of the automobile steering column locker; when the control handle is pushed, the control handle can drive the control cam 3 to synchronously act.
A plurality of guide sliding blocks 9 are uniformly distributed on the circumferential surface of the extrusion cylinder 7 (see the attached figure 1 of the specification); the extrusion container 7 is connected with a guide sliding groove of the limiting sleeve 8 in a sliding manner through a guide sliding block 9; the purpose of so setting the guide slider 9 is: when the extrusion container 7 is stressed, the extrusion container 7 can only move up and down in the extrusion container 7 under the action of the guide slide block 9 and the guide sliding groove of the extrusion container 7; thereby avoiding the problem of the container 7 falling out of the path of movement.
A plurality of triangular pushing openings 10 are uniformly distributed on the lower end surface of the extrusion cylinder 7 (see the attached figure 1 in the specification).
A limiting pin 6 is arranged at the coarse hole part of a limiting sleeve 8 at one side of the extrusion container 7 in a sliding way (see the attached figure 3 in the specification); the circumferential surface of the limit pin 6 is provided with a stop ring 11 (see the attached figure 1 in the specification).
A plurality of pushing ribs 12 are uniformly distributed on the limiting pin 6 on one side of the baffle ring 11 (see the attached figure 1 in the specification); the upper end of the pushing rib 12 is arranged opposite to the pushing port 10; the structure of the upper end head of the pushing rib 12 is consistent with that of the pushing port 10; the upper end of the limiting pin 6 extends into the extrusion container 7; the upper end of the pushing rib 12 is connected with the pushing port 10 in a clamping manner. Therefore, when the extrusion container 7 moves, the extrusion container 7 can push the limiting pin 6 to act through the pushing port 10 and the pushing rib 12, and the limiting pin 6 can be ensured to press the track to act under the pushing of the extrusion container 7.
A return spring 5 is sleeved on the limit pin 6 on the other side of the baffle ring 11; the return spring 5 is respectively connected with the shell 2 and the baffle ring 11 in an abutting mode. Under the action of the elastic force of the return spring 5, the limit pin 6 always tends to retract into the limit sleeve 8.
When people stir the control handle of the locker to unlock the locker, the height of the automobile steering column is adjusted; when the control handle rotates, the control cam 3 is driven to rotate at the same time, so that the control cam 3 pushes the extrusion container 7 to act; when the control handle stops rotating, the "protruding" part of the control cam 3 interferes with the container 7; at the moment, under the action of the control cam 3, the extrusion cylinder 7 pushes the limiting pin 6 to overcome the elastic force of the return spring 5, and then one end of the limiting pin enters the limiting groove 13 of the sleeve 1; at this moment, under the cooperation of the limiting pin 6 and the limiting groove 13, the relative movement position of the shell 2 and the sleeve 1 can be limited, so that the adjusting height of the automobile steering column can be limited, and then people can adjust the height of the automobile steering column according to needs.
After the height of the automobile steering column is adjusted, people stir the control handle of the locker to lock the locker, the control handle can drive the control cam 3 to rotate simultaneously, and finally the concave part of the control cam 3 is in abutting connection with the extrusion cylinder 7; at the moment, the extrusion container 7 and the limiting pin 6 are restored to the initial positions under the action of the elastic force of the return spring 5; at the moment, the limit pin 6 is separated from the limit groove 13 of the sleeve 1; therefore, when the automobile steering column contracts, the limiting assembly cannot obstruct the automobile steering column from contracting, and the problem of increase of energy absorption force cannot be caused, so that the problem existing in the conventional limiting structure is solved.
As a variation of the present invention; the adjusting and limiting assembly of the automobile steering column consists of a control panel 14, an assembling sleeve 15 and a sliding pin 16 (see the attached figure 5 in the specification); the shell 2 is provided with an assembly sleeve 15 through threads; a sliding pin 16 is arranged in the assembling sleeve 15 in a sliding way; a control panel 14 is arranged on the shell 2 at one side of the sliding pin 16; the control panel 14 is provided with a control chute 17; one end of the sliding pin 16 is connected with the control chute 17 in a sliding way through a pushing pin (not shown in the attached drawings). The control panel 14 is connected to a control handle of a steering column locker of the vehicle. When the control handle works, the control panel 14 can be driven to rotate back and forth; when the locker is in a locked state, the sliding pin 16 is in a state of being separated from the limiting groove 13 of the sleeve 1; when the locker is in an unlocked state, the sliding pin 16 is in sliding connection with the limiting groove 13 of the sleeve 1 under the action of the control disc 14; the sliding pin 16 can play a role in limiting. According to the deformation structure of the adjusting and limiting assembly, when the height of the automobile steering column is adjusted, a limiting pin in the limiting assembly is in sliding connection with a limiting groove in a sleeve; the limiting component can play a limiting role; when the automobile steering column normally works, the limiting component is in a state of being separated from the sleeve, so that when the automobile steering column collapses, the problem of increased suction capacity cannot be caused by the limiting component; thereby meeting the use requirements of people.
The adjusting and limiting assembly of the automobile steering column has a simple structure and is ingenious in design; the problem that when the automobile steering column collapses, the existing limiting structure can increase the energy absorption capacity and harm drivers and passengers is solved; the requirements of people for use are met.
