Abstract
Disclosed is a lock opening device of an automobile electric steering column, which comprises a middle shaft, an endurance ring arranged on the middle shaft and a lock opening casing mounted outside the endurance ring. A plurality of lock openings are arranged on the lock opening casing, the endurance ring is unsealed, and projected ribs are fully distributed on the outside of the endurance ring. The utility model utilizes the endurance ring to replace welding joint and the endurance ring is disposed between the middle shaft and the lock opening casing, which fulfills the function of fixing the lock opening casing on the middle shaft and avoids the problem that vehicles are stolen because of the lock opening fracture caused by the welding means utilized by prior art. Additionally, compared with conventional welding type lock openings, the quantity of existing lock opening structures is larger, thereby keys of vehicle locks are more convenient to be fetched out when users park vehicles and whirl steering wheels.
Description
Technical field
The utility model relates to the automobile power steering device, relates in particular to the fore shaft device of motorcar electric steering column.
Background technology
The fore shaft device of motorcar electric steering column, device is on the tween drive shaft of electric powered steering tubing string, and its effect is to be used to install the lock device, plays antitheft purpose, and the restriction bearing circle is in the not rotation under the starting state of driving engine.Existing locking notch structure is to be welded on the tween drive shaft of electric powered steering tubing string, is prone to rack of fusion, makes fore shaft portion break, and the weld can be destroyed with knocking energetically also, causes vehicle stolen.
The utility model content
The problem that the utility model leans at the fore shaft device not prison welding of above-mentioned motorcar electric steering column, having carried out research improves, provide a kind of and replace welding, the novel lock mouth structure that original locking notch structure and electric powered steering tubing string tween drive shaft are coupled together with the endurance ring.
The technical solution of the utility model:
The fore shaft device of motorcar electric steering column comprises tween drive shaft, also comprises the endurance ring of device on tween drive shaft, and the fore shaft cover of device outside the endurance ring, has fore shaft above the described fore shaft cover.
Further, described endurance ring is not for sealing the endurance ring, and the outside is covered with protruding stupefied; Described fore shaft can be for a plurality of.
Technique effect:
The utility model adopts the endurance ring to replace welding, and the endurance loop device plays that the fore shaft cover is fixed on effect on the tween drive shaft between tween drive shaft and fore shaft cover, has avoided original technology to adopt the mode of welding easily to produce fore shaft and has broken and cause the stolen problem of vehicle; Simultaneously, the tween drive shaft that is subjected to drive electric powered steering tubing string under the action of gravity at bearing circle rotates, and can't allow fore shaft cover and exterior lock device rotate thereupon, and fore shaft is difficult for breaking, and anti-theft feature is strong; Fore shaft increases with respect to original solder type locking notch structure quantity, can be when stopping, and it is more convenient to take out the lock key when circling round bearing circle.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A-A cutaway view among Fig. 1;
Fig. 3 is in the structural representation of locking-in state for the utility model and external lock device.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
See Fig. 1, the utility model comprises tween drive shaft 1, and tween drive shaft 1 is parts of motorcar electric steering column; See Fig. 2, the device ring 3 that has legs on tween drive shaft 1, endurance ring 3 is closed-loop not, the outside of endurance ring 3 is covered with protruding stupefied 5, and the bore of endurance ring 3 is little than tween drive shaft 1, and adopts with the connection mode of tween drive shaft and to be pressed into earlier, back extrusion molding guarantees to connect closely and fastness; See Fig. 1, Fig. 2, at the outside of endurance ring 3 device fore shaft cover 2 is arranged, the bore of fore shaft cover 2 is less than the bore that is installed in the endurance ring 3 on the tween drive shaft 1, and also adopt earlier with the connection mode of endurance ring 3 and tween drive shaft 1 and to be pressed into, back extrusion molding, and protruding stupefied 5 embed fore shaft when the extruding and overlap 2 inboards by what the endurance ring outside was covered with, what guaranteed fore shaft cover 2 and endurance ring 3 is connected compactness and fastness; See Fig. 1, have fore shaft 4 on the fore shaft cover 2, fore shaft 4 can be made as a plurality of, and the bearing circle that circles round fast during convenient the parking is extracted car key.
Working process of the present utility model is as described below:
See Fig. 3, when exterior lock device is carried out the pinning action, the lock tongue 6 of lock device enters 4 li of the fore shafts of fore shaft cover 2, make lock be in locking-in state, at this moment, because the effect of lock tongue 6 has limited the rotation of fore shaft cover 2, endurance ring 3 and tween drive shaft 1, has also limited the rotation of the bearing circle that is connected with the electric powered steering tubing string simultaneously; When exterior lock device is carried out opening action, the lock tongue 6 of lock device leaves the fore shaft 4 of fore shaft cover 2, lock is in non-locking-in state, at this moment, fore shaft cover 2, endurance ring 3 and tween drive shaft 1 can be connected bearing circle on the electric powered steering tubing string and carry out synchronously and rotate.
Claims (4)
1. the fore shaft device of motorcar electric steering column comprises tween drive shaft, it is characterized in that also comprising the endurance ring of device on tween drive shaft, and the fore shaft cover of device outside the endurance ring, has fore shaft above the described fore shaft cover.
2. according to the fore shaft device of the described motorcar electric steering column of claim 1, it is characterized in that described endurance ring is not for sealing the endurance ring.
3. according to the fore shaft device of claim 1 or 2 described motorcar electric steering columns, it is characterized in that the described endurance ring outside is covered with protruding stupefied.
