Description

Technical Field

[0001] The present invention relates to the technical field of locks, and in particular to an electric-controlled auxiliary lock with an unlocking function. The present invention also relates to an electric-controlled lock comprising the electric-controlled auxiliary lock with the unlocking function. Background Art

[0002] Since electric locks do not need to carry mechanical keys and are easy to use, they are loved by people. At present, the motor-controlled automatic locks on the market often need to install mechanical emergency lock cylinders to prevent people from being locked out of the door, but the structure of the mechanical emergency lock cylinder is relatively complex, and it is troublesome to install and use. In addition, for ordinary electric control auxiliary locks with unlocking function, there is only one main lock point, and it is usually necessary to add a slant tongue structure to cooperate with the windproof function of the door body. In this way, the door must be opened with the help of a handle, and the set slant tongue structure is inconvenient for cooperating with the fully automatic door opening and closing system, and affects the use of the fully automatic door opening and closing system. In addition, for electric control locks, power supply is particularly important, and the current electric control locks are generally powered by batteries. When the battery is exhausted or the power is low, it greatly affects the normal operation of the lock. And there are many problems in battery replacement, such as inconvenient replacement, high cost, and environmental protection. Summary of the invention

[0003] In view of this, the present invention aims to provide an electrically controlled secondary lock with an unlocking function, so that when the main lock is locked, the lock of the main lock body and the secondary lock body can be released, thereby realizing the opening of the door body.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0005] An electrically controlled secondary lock with an unlocking function can be installed on a door body in cooperation with a main lock body provided with a main lock tongue, wherein the main lock tongue is provided in the main lock body and can extend or retract relative to the main lock body. The electrically controlled secondary lock with an unlocking function comprises:

[0006] A secondary lock body, on which a cover plate is turned over and provided, and when the cover plate is in a buckled and locked state, a lock hole for inserting the main lock tongue is formed between the cover plate and the secondary lock body;

[0007] A driving component is arranged in the secondary lock body, and the driving component includes a driving source, and a blocking portion arranged at the power output end of the driving source and capable of causing the cover plate to maintain the snap-fitting and locking state. Corresponding to the blocking portion, a limiting portion abutting against the blocking portion is provided on the cover plate. Due to the drive of the driving source, the blocking portion can be separated from the limiting portion to release the snap-fitting and locking state of the cover plate, so that the cover plate can be flipped toward the inner side of the door body around the flipping center.

[0008] Furthermore, a connecting flap is pivotally provided on the auxiliary lock body, and the free end of the connecting flap constitutes the blocking portion. The driving source can receive an external signal and can have a linear reciprocating motion to pull the connecting flap to rotate, thereby constituting the separation of the blocking portion and the limiting portion.

[0009] Furthermore, a transmission connecting rod is hinged on the connecting flap, and relative to one end hinged to the connecting flap, the other end of the transmission connecting rod is hinged to the power output end of the driving source.

The electrically controlled secondary lock with unlocking function described in the present invention is relatively simple in structure and cleverly designed, so that the door can be opened when the main lock body cannot be opened. At the same time, the electrically controlled secondary lock can replace the mechanical lock core for emergency unlocking, thereby having a better use effect.

[0014] (2) By setting up a connecting flap, on the one hand, it can be convenient to block and limit the cover plate through its free end, and on the other hand, it can be convenient to connect with the driving source and be driven to rotate by the driving source, thereby realizing the separation of the blocking part and the limiting part.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0040] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0041] Embodiment 1

[0042] The present embodiment relates to an electric-controlled auxiliary lock with an unlocking function (hereinafter referred to as the electric-controlled auxiliary lock), which can be installed on a door body in cooperation with a main lock body 1 provided with a main lock tongue 10, wherein the main lock tongue 10 is arranged in the main lock body 1 and can extend or retract relative to the main lock body 1. An exemplary structure of the electric-controlled auxiliary lock of the present embodiment is as follows Figure 1 As shown, the electric control auxiliary lock includes an auxiliary lock body 2 and a driving component arranged in the auxiliary lock body 2. Figure 1 Combination Figure 2 and Figure 3As shown, a cover plate 21 is flipped on the auxiliary lock body 2. In the buckled and locked state, the cover plate 21 can be formed with the auxiliary lock body 2 to form a lock hole 20 for the main lock tongue 10 to be inserted. The driving component includes a driving source 23, and a blocking portion 221 provided at the power output end of the driving source 23 and capable of maintaining the cover plate 21 in the buckled and locked state. Corresponding to the blocking portion 221, a limiting portion 211 abutting against the blocking portion 221 is provided on the cover plate 21. Due to the drive of the driving source 23, the blocking portion 221 can be separated from the limiting portion 211 to release the buckled and locked state of the cover plate 21, so that the cover plate 21 can be flipped around the flipping center toward the inner side of the door body to realize the opening of the door body.

[0043] For details, see Figure 1 As shown, one end of the cover plate 21 is turned over by the first pivot shaft 27 arranged on the bottom of the auxiliary lock body 2, and a stepped groove is constructed at the other end of the cover plate 21 relative to the pivotally connected end, and the groove constitutes the aforementioned limiting portion 211. In the buckled locking state of the cover plate 21, the cover plate 21 and the auxiliary lock body 2 surround and form a lock hole 20 for the main lock tongue 10 to be inserted, wherein a connecting flap 22 is pivotally arranged on the auxiliary lock body 2, and the free end of the connecting flap 22, that is, the end opposite to the pivotal connection, is constructed with a flange bent and extended along one side of the connecting flap 22, and the flange can abut against the aforementioned groove, and the flange constitutes the aforementioned blocking portion 221. The aforementioned driving source 23 can receive an external signal and can have a linear reciprocating motion to pull the connecting flap 22 to rotate, so that the blocking portion 221 can be separated from the limiting portion 211.

[0044] In order to facilitate the driving source 23 to pull the connecting flap 22 and realize the rotation of the connecting flap 22, in this embodiment, a transmission connecting rod 231 is hinged on the connecting flap 22, and relative to one end hinged to the connecting flap 22, the other end of the transmission connecting rod 231 is hinged to the power output end of the driving source 23.

[0045] It should be noted that the driving source 23 can be driven by a cylinder, a linear motor 11 or a push-pull electromagnet, etc., and is preferably a push-pull electromagnet in the present embodiment, and one end of the aforementioned transmission connecting rod 231 is hingedly connected to one end of the moving iron magnet of the push-pull electromagnet. Compared to adopting a cylinder or a linear motor 11, etc., the push-pull electromagnet has a relatively simple structure and low cost, and has the advantages of being compact and convenient for installation and arrangement. In addition, the driving source 23 can also be a stepper motor 11 that directly acts on the blocking portion 221, and the rotation setting of the blocking portion 221 is driven by controlling the intermittent rotation of the stepper motor 11, and only the installation arrangement and the arrangement space of the stepper motor 11 need to be adapted and adjusted.

[0046] In order to facilitate the cover plate 21 to be able to be promptly reset to the engaged state after being flipped over, a first elastic reset member 213 is provided between the cover plate 21 and the auxiliary lock body 2. The first elastic reset member 213 is a torsion spring sleeved on the first pivot shaft 27. After the cover plate 21 is flipped open due to an external force, it can be fastened and reset under the elastic force of the torsion spring. In order to prevent the cover plate 21 from being over-flipped during the fastening and resetting process, an anti-rotation end surface 212 is constructed on the cover plate 21.

[0047] In order to enable the connecting flap 22 to flip and reset when the push-pull electromagnet loses power, in the present embodiment, a second elastic reset member 222 is provided between the connecting flap 22 and the auxiliary lock body 2. The second elastic reset member 222 is a torsion spring sleeved on the second pivot shaft 28. When the push-pull electromagnet loses power, the connecting flap 22 can be rotated and reset under the elastic force of the torsion spring to smoothly engage with the cover plate 21, that is, the blocking portion 221 can smoothly abut against the limiting portion 211, thereby realizing the engaging and locking state of the cover plate 21.

[0048] In addition, in order to facilitate the connection between the auxiliary lock body 2 and the external component, wherein the external component can be a door body or a door frame, the auxiliary lock body 2 of this embodiment is fixedly connected to the fixing seat 3, and the fixing seat 3 is provided with a mounting hole that can be connected to the external component.

[0049] When the electric control secondary lock of this embodiment is in use, the push-pull electromagnetic is energized to drive the transmission connecting rod 231 and the connecting flap 22 to rotate, so that the blocking portion 221 is separated from the limiting portion 211, that is, the cover plate 21 is released from the buckled and locked state, and then the cover plate 21 can be flipped under the push of the main lock tongue 10 to realize the opening of the door body. After the door body is opened, the cover plate 21 is in a buckled and locked state under the elastic force of the first elastic reset member 213, and the push-pull electromagnetic is de-energized, and the connecting flap 22 is rotated and reset under the elastic force of the second elastic reset member 222, so that the blocking portion 221 is abutted against the limiting portion 211, and then the cover body 29 is in a buckled and locked state.

[0050] The electric-controlled secondary lock of this embodiment can open the door when the main lock body 1 cannot be opened by means of the reversible cover plate 21, the connecting flap 22 and the push-pull electromagnet, thereby replacing the mechanical lock core for emergency unlocking. At the same time, the electric-controlled secondary lock has a relatively simple structure and ingenious design, and has a good use effect.

[0051] Embodiment 2

[0052] This embodiment relates to an electric control lock, which includes a main lock body 1 and an electric control secondary lock with an unlocking function as described in the first embodiment and used in conjunction with the main lock body 1. An exemplary structure of the electric control lock is as follows: Figure 2 and Figure 3As shown, a connector is provided on the main lock body 1 and the auxiliary lock body 2, and the connector includes a first connecting component and a second connecting component respectively provided on the main lock body 1 and the auxiliary lock body 2. Among them, the first connecting component has a first connecting terminal 30 which is convex and connected to a power line, and the first connecting terminal 30 is elastically limited on the main lock body 1 and can reciprocate relative to the main lock body 1 along the extension direction of the main lock tongue 10. The second connecting component has a second connecting terminal 40 which can abut against the first connecting terminal 30, and a magnetic attraction part 26 is provided on the second connecting terminal 40; when the door body is closed, the first connecting terminal 30 and the second connecting terminal 40 are pressed against each other due to the elastic force and the magnetic attraction of the magnetic attraction part 26.

[0053] The electric control lock of this embodiment not only has the electric control secondary lock with the unlocking function, but also the connector provided can make the first terminal 30 and the second terminal 40 firmly fit together and not easily disconnected under the action of the elastic force and the magnetic attraction part 26 when the door body is in the closed state, thereby not only realizing the conduction of the circuit, but also playing a certain windproof role.

[0054] In terms of specific structure, combined Figures 2 to 4 As shown, the main lock body 1 of this embodiment includes a main lock tongue 10 in the shape of a rectangular block arranged in the main lock body 1, and a driving mechanism for driving the main lock tongue 10 to extend or retract into the main lock body 1, wherein the driving mechanism includes a motor 11, a driving gear 111 arranged at the power output end of the motor 11, a first gear 12 meshed with the driving gear 111, and a lock tongue connector 13 connected to the first gear 12 and hingedly connected to the main lock tongue 10. Through the above-mentioned structural arrangement, the first gear 12, the lock tongue connector 13 and the main lock tongue 10 constitute a similar crank slider mechanism, and the rotation of the driving main wheel drives the first gear 12 to rotate, so that the first gear 12 pulls the lock tongue connector 13 to move, thereby driving the sliding of the main lock tongue 10, and by controlling the rotation direction of the first gear 12, the sliding extension or sliding retraction of the main lock tongue 10 into the main lock body 1 is controlled to complete locking or unlocking.

[0055] The main lock body 1 of this embodiment is also provided with an interlocking mechanism. Specifically, a second gear 14 is also meshed with the first gear 12. The interlocking mechanism includes a first electromagnet 15 provided on the main lock body 1 and capable of receiving an external control signal and having an extended or retracted state, and a limiting column provided on the power output end of the first electromagnet 15. When the power output end of the first electromagnet 15 is extended, the limiting column can be pressed against the limiting end face provided on the second gear 14. Thus, when the limiting column is pressed against the limiting end face, the main lock tongue 10 on the main lock body 1 cannot be extended or retracted into the main lock body 1. That is, by energizing the electromagnet, the limiting column can be extended to press against the limiting end face to prevent the rotation of the second gear 14, thereby preventing the first gear 12 from rotating to complete locking or unlocking. By de-energizing the electromagnet, the limiting column can be retracted to release the pressing against the limiting end face, and at this time, the rotation of the second gear 14 can be achieved by an external operating force. In addition, a lock core is provided on the rotating shaft of the second gear 14 so that mechanical unlocking can also be achieved. The external operating force mentioned above can specifically be the rotational force of a key or an unlocking knob 50 .

[0056] In order to enable the main lock tongue 10 to slide in the main lock body 1, in this embodiment, a slide rail 19 with a T-shaped cross-sectional structure is fixedly provided on the main lock body 1. Correspondingly, a T-shaped slide groove is provided on the main lock tongue 10, which passes through the main lock tongue 10 and is adapted to the slide rail 19.

[0057] In order to facilitate the anti-locking function of the main lock body 1, an anti-locking component 16 that slides in a direction perpendicular to the extension direction of the main lock tongue 10 is provided on the main lock body 1 near the main lock tongue 10, so that after the main lock tongue 10 is extended, the anti-locking component 16 can slide upward to prevent the main lock tongue 10 from retracting into the main lock body 1, thereby realizing the anti-locking function of the main lock body 1.

[0058] It should be noted here that the drive mechanism, interlocking mechanism, and mechanical unlocking structure memory anti-locking component 16 of the main lock tongue 10 on the main lock body 1 can all adopt mature structures in the prior art and will not be described in detail here.

[0059] As one of the improvements of this embodiment, the connector of this embodiment is composed of Figure 2 , Figure 3 and Figure 4 Combined with Figure 1As shown, the connector includes a first connection component provided on the main lock body 1 and a second connection component provided on the auxiliary lock body 2. In order to facilitate the first connection terminal 30 to be elastically limited on the main lock body 1 and to be reciprocating relative to the main lock body 1 along the extension direction of the main lock tongue 10, the first connection component in this embodiment includes a mounting shell 41 provided on the main lock body 1 and reciprocating along the extension direction of the main lock tongue 10, and the first connection terminal 30 is plugged and connected in the mounting shell 41. Thus, the reciprocating movement of the first connection terminal 30 is achieved by the reciprocating movement of the mounting shell 41 along the extension direction of the main lock tongue 10. In addition, an elastic member 6 is provided between the main lock body 1 and the mounting shell 41, one end of the elastic member 6 is fixedly connected to the main lock body 1, and the other end is fixedly connected to the mounting shell 41. Due to the provision of the elastic member 6, the mounting shell 41 can be elastically limited on the main lock body 1, that is, the first connection terminal 30 is elastically limited on the main lock body 1.

[0060] Specifically, Figure 3 , Figure 4 and Figure 5 As shown, in order to facilitate the installation of the mounting shell 41 on the main lock body 1, a mounting portion 4 is provided on the main lock body 1, and the mounting portion 4 includes mounting blocks arranged at intervals and fixedly connected to the main lock body 1, and baffles fixedly connected to the top of each of the mounting blocks, and a guide groove is formed between two adjacent mounting blocks and the baffles, and the mounting shell 41 is slidably arranged in the guide groove. In addition, a mounting seat 5 for mounting the elastic member 6 is fixedly connected to the main lock body 1, and the cross section of the mounting seat 5 is U-shaped, one end of the elastic member 6 is fixedly connected to the mounting seat 5, and the other end is fixedly connected to the fixed end 411 formed on the mounting shell 41.

[0061] like Figures 5 to 8 As shown, the first connection assembly of this embodiment further includes a roller 42 rotatably arranged on the mounting shell 41, the axial direction of the roller 42 is perpendicular to the extension direction of the main lock tongue 10, and the first wiring terminals 30 are two respectively arranged on both sides of the roller 42. By setting the roller 42, when the door body is closed, the roller 42 can assist the mounting shell 41 to be compressed into the main lock body 1, so that the first wiring terminal 30 on the mounting shell 41 can always be pressed against the second wiring terminal 40 under the elastic force of the elastic member 6.

[0062] Specifically, Figure 7 As shown, the mounting shell 41 is configured with a roller mounting cavity 412 for mounting the roller 42, and an insertion cavity 413 for inserting and connecting the first wiring terminal 30, wherein the structure of the first wiring terminal 30 is shown in FIG8 , and the first wiring terminal 30 includes a long strip-shaped main body 401, and an arc-shaped abutting surface 402 formed at one end of the main body 401. The arc-shaped abutting surface 402 is abutted against the second wiring terminal 40, thereby improving the connection effect between the first wiring terminal 30 and the second wiring terminal 40.

[0063] In this embodiment, a mounting frame 24 is fixedly connected to the secondary lock body 2. The mounting frame 24 is in the shape of a long strip, and a plurality of mounting grooves 241 are arranged at intervals along the length direction thereof, the number of which corresponds to the number of the first wiring terminals 30. The aforementioned second wiring terminal 40 and the magnetic attraction portion 26 are fixedly connected together by bonding, and the assembly fixedly connected by the second wiring terminal 40 and the magnetic attraction portion 26 is slidably installed in the mounting groove 241, wherein the second wiring terminal 40 is arranged on the outside and can protrude from the mounting frame 24. A secondary lock PCB board 25 is fixedly connected to the other side of the mounting frame 24 relative to the side where the second wiring terminal 40 is arranged. The secondary lock PCB board 25 is provided with a copper spring 251 that can abut against the second wiring terminal 40, so that when the first wiring terminal 30 abuts against the second wiring terminal 40, the second wiring terminal 40 can press the copper spring 251 through a magnet, so that the copper spring 251 is connected to the contact on the PCB board.

[0064] In addition, in this embodiment, a lithium battery 18 and a main lock PCB board 17 are also provided on the main lock body 1. It should be noted that the connection and control methods of the electrical components such as the first wiring terminal 30 and the second wiring terminal 40, the main lock PCB board 17 and the auxiliary lock PCB board 25, and the control circuit in this embodiment all adopt existing mature technologies. In addition, it should be noted that the elastic member 6 in this embodiment is preferably a spring, and the magnetic attraction portion 26 is preferably a magnet.

[0065] In addition, it should be noted that the mounting shell 41 on which the first terminal 30 is installed is on the main lock body 1, that is, a movable gap of 8-10 mm can be reserved in the guide groove, and the component to which the second terminal 40 is fixedly connected to the magnetic attraction portion 26 is on the auxiliary lock body 2, that is, a movable gap of about 2 mm can be reserved in the mounting groove 241, so that when the door body vibrates, the first terminal 30 and the second terminal 40 can be kept in a stable fitting state, thereby realizing the connectivity of the circuit and charging the lithium battery 18 arranged on the main lock body 1 to ensure continuous power supply to the electric control lock.

[0066] When the electric lock of this embodiment is in use, it is specifically described in detail when the door is in a closed state. When the door is in a closed state, the first terminal 30 and the second terminal 40 can be firmly attached through the combined action of the provided magnet and the thrust of the spring, so that not only can the circuit be conducted, so as to be able to charge the lithium battery 18, and ensure that the electric lock has the advantages of continuous power and stable and reliable power supply, but also can prevent the door from shaking due to wind, so as to play a better windproof role, and compared with the windproof structure using a handle and a tilted tongue in the prior art, it has significant advantages and better use effects.

[0067] The electric-controlled lock of the present invention, by applying the electric-controlled secondary lock with unlocking function of embodiment 1, can not only open the door when the main lock body 1 cannot be opened, but also charge the power supply of the lock to provide continuous power.
