DETAILED DESCRIPTION

[0030] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0031] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0032] like Figure 1-Figure 8 As shown, an end door lock comprises:

[0033] The locking assembly and the unlocking assembly include a limiting portion 100 and a rotatable locking portion 101, wherein the locking portion 101 is used to connect with the lock body;

[0034] The unlocking assembly includes an unlocking part 200, a first unlocking member and a second unlocking member. The unlocking part 200 can only move in a straight line direction, and the first unlocking member includes an electromagnetic lock cylinder 201, and the second unlocking member includes a key lock cylinder 202. The electromagnetic lock cylinder 201 and the key lock cylinder 202 are both connected to the unlocking part 200, and the unlocking part 200 is connected to the limiting part 100;

[0035] When the door lock is in the locked state, the locking portion 101 is connected to the limiting portion 100, and the locking portion 101 is limited in the locked state;

[0036] When the first unlocking member or the second unlocking member is unlocked and triggered, the first unlocking member or the second unlocking member drives the unlocking portion 200 to move the limiting portion 100 , thereby releasing the locking restriction on the locking portion 101 .

[0037] In this embodiment, the end door lock has two different unlocking methods. One is the electromagnetic unlocking method, which can remotely control the opening of the door lock through access control or network, and is suitable for occasions that require centralized management or remote operation. The other is the key unlocking method. Even in the event of a power outage or system failure, it can be unlocked with a physical key to ensure that entry and exit are still possible in an emergency. For some users or scenarios that do not require frequent changes in permissions, using key unlocking is more direct and convenient. The two different unlocking methods can be assigned to different operators for easy authorization management, and it is also convenient to distinguish which door opening method is recorded.

[0038] Specifically, the locking portion 101 is provided with a locking groove 102, and the unlocking portion 200 can drive the limiting portion 100 to extend into the locking groove 102, and along the rotation direction of the locking portion 101, abutment portions 312 are provided on both sides of the limiting portion 100, and a gap is provided between the two abutment portions 312 to form a moving groove 313, and the locking portion 101 is located in the moving groove 313 and can move in the moving groove 313;

[0039] When the door lock is in a locked state, the first end of the limiting portion 100 extends into the locking groove 102, and the second end of the limiting portion 100 extends into the moving groove 313;

[0040] When the first unlocking member or the second unlocking member is unlocked and triggered, the first unlocking member or the second unlocking member drives the unlocking part 200 to drive the limiting part 100 to move, so that the second end of the limiting part 100 moves out of the moving groove 313, and the locking part 101 is unlocked; during the unlocking rotation process of the locking part 101, the limiting part 100 abuts against the abutting part 312.

[0041] In this embodiment, the locking portion 101 has two states, a locked state and an unlocked state. The locking portion 101 and the lock body are transmitted through the connecting square shaft 500. When the first end of the limiting portion 100 extends into the locking groove 102 and the second end of the limiting portion 100 is located in the movable groove 313, if the locking portion 101 wants to rotate at this time, the groove wall of the movable groove 313 and the limiting portion 100 will abut against each other to restrict the locking portion 101; and when the unlocking portion 200 pushes the limiting portion 100 to move out of the movable groove 313, the second end of the limiting portion 100 is higher than the movable groove 313, then the limiting portion 100 has no blocking effect on the locking portion 101, and the locking portion 101 can rotate at this time, and during the rotation process, the unlocking portion 200 provides support for the limiting portion 100, so that it smoothly transitions to abut against the abutting portion 312.

[0042] It is worth mentioning that, as an optional solution, electromagnetic unlocking can use an access card.

[0043] Further preferably, the second end portion of the limiting portion 100 is provided with an arc chamfer 103, so that when the limiting portion 100 moves from the unlocking portion 200 to the abutting portion 312, the transition is smoother, thereby reducing the risk of hard collision and jamming between the two.

[0044] Preferably, a locking resetting portion is provided on the locking portion 101 to enable the locking portion 101 to automatically rotate from the unlocked state to the locked state.

[0045] Specifically, the locking reset portion includes an installation portion 300 and a reset portion 301, an elastic member 302 is arranged between the installation portion 300 and the reset portion 301, an end of the reset portion 301 is in contact with the outer contour of the locking portion 101, and the outer contour of the locking portion 101 is provided with an initial position 303 which is closest to the straight-line distance from the rotation center of the locking portion 101, and a reset position 304 which is farthest from the straight-line distance from the rotation center of the unlocking lock tongue 308, wherein the initial position 303 and the reset position 304 are smoothly transitioned by an arc, when the locking portion 101 is in a locked state, the initial position 303 on the outer contour of the locking portion 101 is in contact with the reset portion 301, and when the locking portion 101 is in an unlocked state, the reset position 304 on the outer contour of the locking portion 101 is in contact with the reset portion 301.

[0046] In this embodiment, a mounting cavity 305 is provided in the mounting portion 300, and the elastic member 302 is located in the mounting cavity 305, and one end of the elastic member 302 abuts against the cavity wall of the mounting cavity 305, and the other end of the elastic member 302 abuts against the reset portion 301, and the reset portion 301 is also located in the mounting cavity 305, so that the reset portion 301 can only move along a straight line direction; in the locked state, the initial position 303 on the locking portion 101 abuts against the reset portion 301, and as the handle 501 is turned to drive the locking portion 101 to rotate and unlock, the outer wheel on the locking portion 101 The contact point between the outer contour and the reset portion 301 gradually moves from the initial position 303 to the reset position 304, and the distance between the rotation center of the reset portion 301 and the locking portion 101 gradually increases, so that the elastic member 302 is compressed and accumulates elastic potential energy; the handle 501 is released, and no force is applied to the locking portion 101, and the compression potential energy of the elastic member 302 is released, driving the reset portion 301 to extend straight out and squeeze the locking portion 101, so that the connection point between the reset portion 301 and the locking portion 101 moves from the reset position 304 to the initial position 303, thereby driving the locking portion 101 to reset.

[0047] Specifically, an abutment section is formed between the initial position 303 and the reset position 304 on the outer contour of the locking portion 101, and the abutment end can be divided into a first unlocking section and a second unlocking section. The increase in the straight-line distance between the first unlocking end and the rotation center of the locking portion 101 gradually increases, while the increase in the straight-line distance between the second unlocking section and the rotation center increases and decreases. In addition, two abutment sections are symmetrically arranged on the outer contour of the locking portion 101, so that a recessed portion 306 is formed between the two abutment sections, and a protruding portion 307 is formed on the reset portion 301. At the initial position 303, the protruding portion 307 is in contact with the recessed portion 306.

[0048] Preferably, a rotation limiting portion 309 is fixedly provided on the mounting portion 300 , a limiting groove 310 is provided on the rotation limiting portion 309 , a limiting column 311 is provided on the locking portion 101 and extends into the limiting groove 310 , and the limiting column 311 can only slide in the limiting groove 310 .

[0049] In this embodiment, an arc-shaped limiting groove 310 is provided on the locking portion 101, and the center of the limiting groove 310 is coaxially arranged with the rotation center of the locking portion 101. As the locking portion 101 rotates, the position of the limiting column 311 in the limiting groove 310 changes, and at the same time, it can also ensure that the movement of the abutment position between the reset portion 301 and the locking portion 101 exceeds the abutment section.

[0050] Specifically, the key lock cylinder 202 is transmission-connected with an unlocking lock tongue 308, and the outer contour of the unlocking lock tongue 308 is in contact with the unlocking part 200. The outer contour of the unlocking lock tongue 308 is provided with a locking position which is closest to the straight-line distance from the rotation center of the unlocking lock tongue 308, and an unlocking position which is farthest from the straight-line distance from the rotation center of the unlocking lock tongue 308. When the key lock cylinder 202 is in a locked state, the locking position on the outer contour of the unlocking lock tongue 308 is in contact with the unlocking part 200, and when the key lock cylinder 202 is in an unlocked state, the unlocking position on the outer contour of the unlocking lock tongue 308 is in contact with the unlocking part 200.

[0051] In this embodiment, as the key lock cylinder 202 is unlocked, the unlocking lock tongue 308 moves from the locked position to the unlocked position as the key rotates, and the straight-line distance between the unlocking part 200 and the unlocking lock tongue 308 increases, so that the driving part drives the limiting part 100 to move and releases the lock on the locking part 101.

[0052] Preferably, it also includes a first detection sensor 400 and a second detection sensor 401. The electromagnetic lock core 201 unlocks and drives the unlocking part 200 to work to the first stroke and triggers the first detection sensor 400; the key lock core 202 unlocks and drives the unlocking part 200 to work to the second stroke and triggers the second detection sensor 401.

[0053] In this embodiment, in order to realize monitoring and recording of two unlocking modes respectively, two detection sensors are set to record the two unlocking modes respectively, as one of the optional solutions, such as Figure 2-Figure 4 As shown, a first trigger part 402 is provided on the unlocking part 200, and a second trigger part 403 is provided on the unlocking lock tongue 308. When the electromagnetic lock cylinder 201 is unlocked, the unlocking part 200 is driven to work to the first stroke, triggering the first detection sensor 400. When the key lock cylinder 202 is unlocked, the unlocking part 200 is driven to work to the second stroke, triggering the second detection sensor 401. The difference between the first stroke and the second stroke is that the extreme positions of pushing the unlocking part 200 to move are different.

[0054] It is worth mentioning that both the first detection sensor 400 and the second detection sensor 401 are micro switches, and both the micro switches are communicatively connected to the access control system.

[0055] Preferably, the locking assembly, the first unlocking member and the second unlocking member are arranged in sequence.

[0056] In this embodiment, the unlocking portion 200 includes an unlocking column, such as Figure 1 As shown, from top to bottom are the reset part 301, the electromagnetic lock core 201 and the key lock core 202, the unlocking column passes through the electromagnetic lock core 201 and abuts against the key lock core 202, and the first detection sensor 400 and the second detection sensor 401 are arranged on both sides of the key lock core 202, located between the electric core lock core and the key lock core 202, and they are reasonably arranged to reduce the occupied space of the entire device.
