An electric vehicle electromagnetic shaft lock

technical field

The utility model relates to a vehicle lock device, in particular to an electric vehicle electromagnetic shaft lock.

Background technique

At present, the lockset that existing electric vehicle adopts is generally all the lockset (as chain lock etc.) that electric vehicle is equipped outside. There are many deficiencies in these external locks adopted by electric vehicles: these external locks have poor anti-theft performance, are exposed outside the electric vehicle, and are easy to be found by thieves and pried off or cut off with tools; in addition, these external locks are almost Mechanical locks that require a key to open are easy to be opened by thieves with unlocking tools, and there are various hidden dangers, which lead to the theft of electric vehicles. Bring very big economic loss to car owner.

Contents of the invention

In order to solve the deficiencies of the above problems, the purpose of this utility model is to provide an electric vehicle electromagnetic shaft lock.

The technical solution adopted by the utility model is: an electromagnet is vertically installed on one side of the lock shell, and an "L"-shaped locking lever with a small curved end facing downward is installed horizontally above the electromagnet. The outer end of the long arm is connected with the return spring of the lock lever, the other end of the long arm of the "L" shaped lock lever is connected with the fulcrum in rotation, and the lock lever sleeve on the other side of the lock shell is equipped with a lock that can slide axially. The side of the lock bar is equipped with a lock bar push handle, one end of the lock bar is equipped with a lock bar return spring, and the other end of the lock bar is equipped with semicircular rubber, which can be connected with the outer ring of the wheel axle of the electric vehicle. The rubber in the shape of the "L" is tightly matched, and the protrusion on the lock rod is located on the inner side of the small bend of the "L"-shaped buckle lock rod, which can be closely matched with the "L"-shaped buckle lock rod. The car power supply is connected into a path.

Compared with the background technology, the utility model has the beneficial effect that the conventional electric car lock is replaced by a mechanical and electrical combination device. Manpower is used for locking, and electromagnetic force is used for unlocking, which breaks the shackles of traditional locks that use keys to unlock. The utility model has the advantages of reasonable and compact structure and good anti-theft performance. In addition, the utility model is easy to manufacture and low in cost, and is worth popularizing and using.

Detailed ways

Below in conjunction with embodiment and accompanying drawing, the utility model is further described.

As shown in Fig. 1, Fig. 2 and Fig. 3, the utility model is equipped with an electromagnet 1 vertically on one side inside the lock housing 6, and an "L"-shaped buckle with the small curved end facing down is installed horizontally above the electromagnet 1. Bar 5, one end of " L " shape buckle lock lever 5 long arms outside is connected with buckle lock lever reset spring 4 , the other end of " L " shape buckle lock lever 5 long arms is connected with fulcrum 11 rotations, the other in the lock housing 6 Lock bar 3 that can do axial sliding is housed in the lock bar cover 10 on one side, and lock bar push handle 9 is equipped with on the side of lock bar 3, and one end of lock bar 3 is equipped with lock bar return spring 7, and the other end of lock bar 3 Equipped with a semicircular rubber 2, the semicircular rubber 2 can closely cooperate with the outer circular rubber 2 of the wheel axle 8 of the electric vehicle, and the protrusion on the lock bar 3 is located at the small bend of the "L"-shaped buckle lock bar The inner surface of the inner surface can be closely matched with the "L" shape buckle lock lever, and the electromagnet 1 is connected into a path through the resistor R, the electric vehicle key hole 12 and the electric vehicle power supply 13.

As shown in Figure 3, the described electric vehicle key hole 12 is divided into three gears of closing gear 12.1, starting gear 12.2, and unlocking gear 12.3.

As shown in Figure 1 and Figure 2, when the protrusion on the lock bar 3 is located on the outer side of the small bend of the "L" shaped lock bar 5, it needs to be locked. Function Push the lock lever push handle 9 to the right, the lock lever push handle 9 can slide in the chute of the lock shell 6, and when the lock lever push handle 9 is pushed to the right, the small end surface of the lock lever 5 is buckled along the protruding slope of the lock lever 3 Rotate clockwise around the fulcrum 11. When the push distance to the right is large enough, when the protrusion on the lock bar 3 is located on the inner side of the small bend of the "L"-shaped lock bar 5, the lock bar 5 will return to the spring on the lock bar. Under the action of 4, turn counterclockwise around the fulcrum 11 to buckle the lock bar 3, and now the rubber on the top of the lock bar 3 is in close contact with the outer rubber 2 of the wheel axle 8, and the locking state has been reached. As shown in Figure 3, when unlocking, insert the starting key of the electric vehicle into the key hole 12 of the electric vehicle, and turn the key to the unlocking gear 12.3. At this time, the electromagnet circuit is turned on. The protrusion and the inner surface of the small bend of the "L"-shaped locking rod 5 do not contact, and the locking rod 5 rotates clockwise under the action of electromagnetic force until the small end surface of the "L"-shaped locking rod 5 is located on the protrusion of the locking rod 3. When the top of the lock bar is released, the lock bar push handle 9 is released, so that the lock bar 3 returns to the initial position under the action of the lock bar return spring 7, that is, the protrusion on the lock bar 3 is located at the small bend of the "L"-shaped buckle lock bar 5. On the outer side, the rubber at the top of the lock bar 3 and the outer rubber 2 of the wheel shaft 8 are loosened, which means unlocking. Then turn the electric car key to the start gear 12.2, and you can drive normally. Electromagnet power supply 13 is provided by electric vehicle power supply. The lock can be mounted on one side of the wheel axle or on both sides of the wheel axle.

The above-mentioned specific embodiments are used to explain the utility model, rather than to limit the utility model. Within the spirit of the utility model and the scope of protection of the claims, any modifications and changes made to the utility model fall into the scope of the utility model. scope of protection.
