Embodiment Construction

[0036] In Fig. 1 to Fig. 15, the automobile anti-theft main brake control device has a base plate 1, on which there is a sliding core type check valve 2 and a cam type bistable trigger 3 connected with the sliding core type check valve,

[0037] The sliding core check valve has a hexahedral valve body 4. There are two oil inlets 5 on the front of the valve body. There are two oil outlets 6 connected to the two oil inlets on the side of the valve body. The valve seat 7 has a valve stem 8 that can slide back and forth in the valve body. The rear end of the valve stem protrudes from the back of the valve body. There is a valve stem coil spring 11 between the valve stem and the valve body. The rear end of the valve stem is connected with a connecting plate 41. The front end of the valve stem is embedded with an elastic spool 9 matching the valve seat, and there is a spool coil spring 10 between the elastic spool and the valve stem.

[0038]The cam type bistable trigger has a hexah...

Abstract

The invention which relates to a car theftproof main brake control device comprises a slip-core check valve and a cam-type double stable state trigger which are connected together; a through hole of the cam-type double stable state trigger is provided with a triggering shaft; the middle part of the triggering shaft is provided with a circumferential groove; a control shaft which is controlled by an edge cam and can be inserted into the groove is arranged between the top side of the trigger body and the through hole; the edge cam is driven to rotate by a push-and-pull type electromagnet through a rack, a gear and a driving ratchet; a retaining ratchet is arranged between the edge cam and the trigger body; the cam-type double stable state trigger can be provided with a stable triggering state and a non-triggering state. A slide core type one way valve is provided with a matching valve base and a valve core, and a valve core spiral spring which is arranged between the valve core and a valve rod can be the one way valve when closed. The car theftproof main brake control device which combines with a remote control switch in the car can cause the main brake of the car to be in a brake state or discharge the brake state of the main brake of the car; when the car is started, under the condition that the main brake is operated, the car can hardly overcome the friction of the main brake to run and the car theftproof device is good in theftproof performance.

Description

technical field [0001] The invention relates to a main brake oil circuit control device for automobile anti-theft, in particular to a main brake oil circuit control valve for automobile anti-theft. Background technique [0002] Theft happens sometimes when the car is parked. In order to prevent the car from being stolen when it is parked, a car brake anti-theft device can be installed on the car. In the prior art, Chinese patent 90 2 10685.6 discloses a car anti-theft device, which is mainly composed of an electrical control device and a hand brake locking mechanism. The brake locking mechanism is installed on the transmission case to control the clutch of the hand brake. When parking, after the hand brake is applied, the hand brake locking mechanism can lock the hand brake. The control device opens the hand brake locking mechanism by the electromagnet to release the hand brake. Otherwise, the hand brake locking mechanism prevents the hand brake from being released, so that...
