Abstract
The present invention relates to a vehicle steering anti-theft device arranged on a steering mast. The present invention has the technical scheme that a subassembly is fixedly arranged on the steering mast, the subassembly forms concave-convex cooperation with a slide block, a power transmission mechanism pushes the slide block to move and is in the position which combines or is separated from the subassembly respectively, and the slide block can only move without rotation in a dump rail. Once the slide block moves to the cooperation position of the fixed subassembly on the steering mast, the steering mast can not move, so the vehicle direction is locked, and achieves the anti-theft aim.
Description
Technical field
The present invention relates to alarms and security systems for automobiles, specifically just be arranged on the locking device on the Steering gear under the vehicle steering.
Background technology
Existing automobile is provided with various anti-joyride devices, the car door lockset is wherein arranged, the lockset of locked bearing circle and gear, wherein Lockset on steering wheel is according to the shape of bearing circle and Position Design basically, on the lockset latch hook or the ring that pins bearing circle arranged on the one hand, also be provided with rod member on the other hand on the lockset, this rod member be positioned at gauge panel above or below, in case lockset is locked bearing circle like this, bearing circle and lockset can't rotate arbitrarily, vehicle just can not cruising like this, thereby reaches theft-proof purpose.This class lockset mode of installing and fixing is the whole shape that exposes, so long as lockset is destroyed, anti-theft feature had both been accused inefficacy.
Summary of the invention
Purpose of the present invention just provides a kind of automobile anti-theft device that is installed on the Steering gear.
For achieving the above object, the present invention has adopted following technical scheme: a kind of automobile anti-theft device, fixedly install parts on the Steering gear, the concave, convex position that is fitted to each other is arranged on slide block and the parts, slide block is provided with Power train, Power train promote slide block move and be in respectively with parts in conjunction with or separate two kinds of location statuss, described slide block is arranged in the slide rail of on-circular cross-section, the direction of slip of slide block is parallel with Steering gear.
When slide block move to Steering gear on during the cooperation position of the parts that fixedly install, Steering gear also can't rotate, the direction of vehicle is just by locked like this, thereby realize antitheft purpose, the present invention is arranged on the locking device on the Steering gear, and this device is in shelters the position, fool proof, be not subject to destruction, therefore have the failure-free anti-theft feature.
Summary of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation that the present invention is in locked position;
Fig. 3 is the structural representation that is made of Power train relay.
The specific embodiment
As shown in Figure 1; automobile anti-theft device comprises parts 20 that fixedly install on the Steering gear 10; be that both are heavy keying fit; parts 20 rotate synchronously during the normal rotation bearing circle; the direction of slip of the slide block 40 in slide rail that is arranged on on-circular cross-section 30 is parallel with Steering gear 10; described slide rail 30 adopts on-circular cross-section to be meant rectangle or channel-section; so just can guarantee that slide block 40 can only move and can not rotate in slide rail 30; on slide block 40 and the parts 20 be fitted to each other recessed arranged; the protuberance position; slide block 40 is provided with Power train; Power train promote slide block 40 move and be in respectively with parts 20 in conjunction with or separate two kinds of location statuss; promptly bearing circle can't rotate when slide block 40 combines with parts 20; and bearing circle can normal rotation when slide block 40 separates with parts 20, and vehicle can cruising.
The concrete structure that stops Steering gear 10 to rotate in the time of can satisfying slide block 40 and cooperate with parts 20 has multiple, and spline fitted of the following stated and in-line or criss-cross fit system are exactly typical case and preferred scheme:
The first: as Fig. 1, shown in 2, described parts 20 are a male splines 21, the slide block 40 that is mated is provided with female splines 41, in, male splines 41,21 importing end has chamfering, the effect that chamfering can play guiding is set, there is the hole of passing through for Steering gear 10 at female splines 41 middle parts, at Fig. 1, in 2, slide block 40 is arranged on the slide rail 30 that surrounds Steering gear 10, the female splines 41 that is provided with on the slide block 40 can be in the below with female splines 41 released states, and at this moment, the rotation of female splines 41 can not run into any obstruction, bearing circle can normal rotation, as shown in Figure 1; When both when cooperating, as shown in Figure 2, the rotation of male splines 21 will run into female splines 41 and hinder, this moment, bearing circle can't normal rotation, vehicle can not travel, and plays the theft-proof effect of locking.Have a marking shape window on the described slide rail 30, its length direction is consistent with the direction of Steering gear 10, and described pull bar 80 is positioned at this marking shape window place, and the top of described parts 20 is provided with postive stop baffle 22.
It two is: the shaft section of described parts 20 is in-line or the concavo-convex position of criss-cross, and the slide block 40 that is mated is provided with cooresponding in-line or the concavo-convex position of criss-cross, and there is the hole of passing through for Steering gear 10 at slide block 40 middle parts.
As realizing that the Power train that slide block 40 moves up and down has multiple scheme, the present invention describes in conjunction with the simplest and reliable basic scheme of following two kinds of structures:
The first: as shown in Figure 1, described Power train comprises motor 50, be connected with screw mandrel 60 on the power take-off shaft of motor 50, and be connected with a pull bar 80 between screw mandrel 60 nut engaged 70 and the slide block 40, screw mandrel 60 is set in parallel in the side of Steering gear 10, in order to guarantee that pull bar 80 links to each other with slide block 40 with nut 70, have a marking shape window on the described slide rail 30, its length direction is consistent with the direction of Steering gear 10, described pull bar 80 is positioned at this marking shape window place, therefore described pull bar 80 can move up and down at this marking shape window place, and the top of described parts 20 is provided with postive stop baffle 22, and this postive stop baffle 22 mainly can play position-limiting action.
It two is: as shown in Figure 3, described Power train comprises relay 90, be connected with a pull bar 80 between shaft-like armature 91 on the relay 90 and the slide block 40, shaft-like armature 91 on the relay 90 is set in parallel in the side of Steering gear 10, magnet coil at relay 90 gets, in the dead electricity process, shaft-like armature 91 is parallel to Steering gear 10 and moves up and down, thereby realizes moving up and down of slide block 40, the separation of finishing inside and outside spline 41,21 with cooperate.
