[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or a specific connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0032] The specific embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0033] like Figure 1-Figure 7 As shown, the utility model proposes a novel electronic door lock, comprising a housing 1, an external handle 11, and an elastic sliding tongue 12 arranged in the housing 1, wherein the elastic sliding tongue 12 passes through a first opening 21 of the housing 1 to lock the door. The external handle 11 acts on the elastic sliding tongue 12, and when a force is applied to the external handle 11, the external handle 11 pushes the elastic sliding tongue 12 to retract from the first opening 21 to the housing 1 to open the door.

[0034] Furthermore, a first clutch device 31 and a limit member 4 are also provided in the shell 1. The first clutch device 31 includes a first motor 311 and a first transmission assembly 312 which is transmission-connected to the first motor 311. The first transmission assembly 312 is connected to the limit member 4. The first transmission assembly 312 drives the limit member 4 to move so as to limit the push of the elastic sliding tongue 12 by the external handle 11.

[0035] Through the above arrangement, when it is necessary to restrict the unlocking of the external handle 11, the first motor 311 can be started to drive the movable limit member 4 to move through the first transmission assembly 312, thereby locking the external handle 11 to limit its push on the elastic sliding tongue 12 and prevent outsiders from opening the door lock through the external handle 11.

[0036] It can be understood that the first clutch device 31 of the utility model can achieve the restriction of the external handle 11 by setting the first motor 311 and the first transmission assembly 312, cooperating with the limit member 4. It has a simple structure, convenient operation, strong mechanical stability, easy production and assembly, improved production efficiency, reduced production costs, and at the same time improved product yield, greatly improving the user experience.

[0037] Furthermore, in this embodiment, the electronic door lock further includes a first mounting groove 101 disposed in the housing 1, and the first mounting groove 101 is used for mounting the elastic sliding tongue 12. Specifically, one end of the first mounting groove 101 extends outward to the housing 1 to form a first opening 21, and the elastic sliding tongue 12 can be slidably disposed in the first mounting groove 101. The elastic sliding tongue 12 includes an elastic member 121 and a sliding tongue 122, and one end of the elastic member 121 abuts against the other end of the first mounting groove 101, and the other end of the elastic member 121 abuts against the sliding tongue 122. Through the above arrangement, when the door lock is in a normal state, the elastic member 121 can give a thrust to the sliding tongue 122, and push the sliding tongue 122 out of the first opening 21, thereby achieving the locking of the door lock.

[0038] Furthermore, in this embodiment, the housing 1 further includes a second opening 22, which is provided on one side of the housing 1 and penetrates the side wall of the first mounting groove 101. The outer handle 11 is provided with a first unlocking lever 111, which passes through the second opening 22 and abuts against the sliding tongue 122. Specifically, in this embodiment, the sliding tongue 122 forms a pushing portion 1221 at one end close to the elastic member 121, and one end of the pushing portion 1221 abuts against the elastic member 121, and the other end abuts against the first unlocking lever 111.

[0039] Through the above arrangement, under the normal state of the door lock, the sliding tongue 122 is pushed by the elastic member 121 and will move toward the direction of the first opening 21 until the pushing portion 1221 abuts against the first unlocking lever 111, and the first unlocking lever 111 forms a blocking force on the sliding tongue 122. At this time, the sliding tongue 122 extends out from the first opening 21 to achieve the closing of the door lock. When a force is applied to the external handle 11, the first unlocking lever 111 can provide a force toward the elastic member 121 to the pushing portion 1221, compressing the elastic member 121, and retracting the sliding tongue 122 from the first opening 21 to the shell 1 to achieve the opening of the door lock.

[0040] Furthermore, in this embodiment, a limiting hole is disposed at one end of the pushing portion 1221 close to the elastic member 121 , and the limiting hole is used for inserting the elastic member 121 to improve the stability of the connection between the elastic member 121 and the pushing portion 1221 .

[0041] Furthermore, in this embodiment, a limiting groove 12211 is provided at one end of the pushing portion 1221 close to the first unlocking lever 111 , and the limiting member 4 can be movably provided on one side of the limiting groove 12211 , and the limiting member 4 can make a reciprocating motion relative to the limiting groove 12211 under the action of the first clutch device 31 .

[0042] Through the above arrangement, when the external handle 11 is restricted, the limiting member 4 can be driven by the first transmission assembly 312 to insert into the limiting groove 12211. At this time, the movement of the first unlocking lever 111 will be blocked by the limiting member 4 to limit the push of the first unlocking lever 111 on the pushing portion 1221. When the restriction of the external handle 11 is released, the same applies and will not be repeated here.

[0043] Furthermore, in this embodiment, in order to facilitate internal personnel to open the door lock, an inner handle 13 is also provided on the other side of the shell 1. The inner handle 13 acts on the pushing portion 1221 to push the elastic sliding tongue 12 to retract from the first opening 21 to the shell 1. Specifically, the shell 1 also includes a third opening 23, which penetrates the side wall of the first mounting groove 101. The inner handle 13 is provided with a second unlocking lever 131, and the pushing portion 1221 is provided with a third unlocking lever 12212. The second unlocking lever 131 penetrates into the third opening 23 and abuts against the third unlocking lever 12212.

[0044] Through the above arrangement, when an inside person unlocks the door, a force can be applied to the inner handle 13 to drive the second unlocking lever 131 to move in the direction of the compression elastic member 121. Since the third unlocking lever is in contact with the second unlocking lever, the second unlocking lever will synchronously drive the third unlocking lever to move, so as to push the elastic sliding tongue 12 to retract from the first opening 21 to the shell 1.

[0046] Through the above arrangement, when the first motor 311 is working, the kinetic energy can be transmitted to the first transmission gear 3122 through the first worm gear 3111 to drive the first transmission gear 3122 to rotate. The rotating first transmission gear 3122 synchronously drives the first transmission shaft 3121 to rotate, and then drives the second transmission gear 3123 to rotate. The limiting member 4 is under the action of the second transmission gear 3123 to realize the reciprocating motion relative to the limiting groove 12211. The structure is simple, the design is ingenious, and the stability is strong.
