[0077] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0078] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0079] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0080] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0081] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0082] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0083] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0084] Figure 1 This is a schematic diagram of the structure of an electronically controlled lock according to one embodiment of the present disclosure (locked state). Figure 2 yes Figure 1 A structural diagram from another angle.

[0085] like Figure 1 and Figure 2As shown, the electric lock disclosed herein includes a lock body 100 and a retaining plate 200. In actual use, the lock body 100 can be fixed to the door, and the retaining plate 200 can be fixed to the door frame or a building near the door. The electric lock can be in a locked state and an unlocked state through the cooperation of the lock body 100 and the retaining plate 200.

[0086] Figure 3 This is a structural schematic diagram of a mouthguard according to one embodiment of the present disclosure.

[0087] like Figure 2 and Figure 3 As shown, the retaining plate 200 includes a first socket 210, a second socket 220, and a third socket 230; wherein the first socket 210, the second socket 220, and the third socket 230 are arranged from bottom to top. Accordingly, the first socket 210 can be used for the insertion of the power module 102, the second socket 220 can be used for the insertion of the main bolt 103, and the third socket 230 can be used for the insertion of the oblique bolt 182. Accordingly, when the main bolt 103 is inserted into the second socket 220, the electric lock is in the locked state; accordingly, when the main bolt 103 is removed from the second socket 220, the electric lock is in the unlocked state.

[0088] In this disclosure, the mouthguard 200 is further provided with a firing device 240. The firing device 240 includes a frame 241 disposed on the mouthguard 200 and a rolling element 242 rotatably disposed on the frame 241. The rotation axis of the rolling element 242 can be vertically arranged, i.e., in... Figure 2 and Figure 3 The frame 241 is positioned vertically so that the firing element 240 can effectively cooperate with the trigger 140. In a preferred embodiment, the position of the frame 241 relative to the guard plate 200 is adjustable, allowing the rolling element 242 to extend beyond the guard plate 200 by different lengths.

[0089] like Figure 3 As shown, the power supply terminal 250 is located inside the first socket 210, and the power supply terminal 250 and the first socket 210 can form a power supply module; correspondingly, the lock body 100 includes a power taking module 102. When the electric lock is in the locked state, the power supply module and the power taking module 102 are connected and conductive; when the electric lock is in the unlocked state, the power supply module and the power taking module 102 are separated.

[0090] Figure 4 This is a schematic diagram of the structure of an electronically controlled lock according to one embodiment of the present disclosure (unlocked state).

[0091] The power supply module 102 can be inserted into or removed from the first socket 210; specifically, as shown in the example... Figure 1 As shown, when the electric lock is in the locked state, the power supply module 102 is inserted into the first socket 210 and electrically connected to the power supply terminal 250; Figure 4 As shown, when the electronic lock is in the unlocked state, the power supply module 102 exits from the first socket 210.

[0092] The following will combine Figures 5 to 8 The structure of the lock body disclosed herein will be described in detail.

[0093] Figure 5 This is a schematic diagram of the lock body according to one embodiment of the present disclosure (locked state). Figure 6 This is a structural schematic diagram of the lock body from another angle (locked state) according to one embodiment of the present disclosure. Figure 7 This is a schematic diagram of the lock body (unlocked state) according to one embodiment of the present disclosure. Figure 8 This is a structural schematic diagram of the lock body from another angle according to one embodiment of the present disclosure (unlocked state).

[0094] like Figures 5 to 8 As shown, the lock body 100 includes a housing 101, the interior of which can form a receiving space, and the lock body 100 can be fixed to the door body by installing the housing 101 onto the door body.

[0095] When the electric lock is in the locked state, at least a portion of the power-taking module 102 extends from the housing 101 and is inserted into the first socket 210; when the electric lock is in the unlocked state, at least a portion of the power-taking module 102 retracts into the housing 101 and exits from the first socket 210. More preferably, when the electric lock is in the unlocked state, the power-taking module 102 can be fully retracted into the housing 101.

[0096] More specifically, when the electronic lock is in the unlocking process, the power supply module 102 is controlled to gradually retract into the housing 101.

[0097] Figure 9 This is a schematic diagram of the main push rod 110 according to one embodiment of the present disclosure.

[0098] like Figures 5 to 9As shown, the lock body 100 also includes a main push rod 110 and a main bolt 103. The main push rod 110 is configured to move up and down relative to the housing 101. When the main push rod 110 moves upward, it drives the power-taking module 102 and the main bolt 103 to move to the left, so that at least a portion of the power-taking module 102 and the main bolt 103 are retracted into the housing 101, thereby realizing the unlocking operation of the electric lock. When the main push rod 110 moves downward, it drives the power-taking module 102 and the main bolt 103 to move to the right, so that at least a portion of the power-taking module 102 and the main bolt 103 are extended to the outside of the housing 101. Correspondingly, when the power-taking module 102 and the main bolt 103 are extended, they can be inserted into the first socket 210 and the second socket 220 respectively, thereby realizing the locking of the electric lock.

[0099] The vertical direction is the same as the vertical direction in the accompanying drawings, or in other words, it is the vertical direction when the lock body 100 is installed on the door. The horizontal direction is perpendicular to the vertical direction, for example... Figure 1 The left and right directions shown in the attached diagram.

[0100] Structurally, the main push rod 110 of this disclosure includes two vertically arranged elongated slots 111, located at the upper and lower ends of the main push rod 110, respectively. Correspondingly, a main push rod guide post 104 is provided on the housing 101, with at least a portion of the guide post 104 slidably disposed within the elongated slots 111, thereby enabling the main push rod 110 to move stably in the vertical direction. More preferably, the guide post 104 can be stepped, comprising two sections of different diameters. The portion within the elongated slots 111 has a smaller diameter, allowing the main push rod 110 to engage with the stepped surface of the guide post 104, thus restricting the rearward position of the main push rod 110. In this disclosure, the forward position of the main push rod 110 can be further restricted by a main tongue 103, etc.

[0101] The main push rod 110 is provided with a first inclined groove 112 and a second inclined groove 113, and the main tongue 103 is provided with a main tongue guide post 105. The main tongue guide post 105 is slidably disposed in the first inclined groove 112, wherein the first inclined groove 112 is inclined upward in the direction from left to right; in this disclosure, the inclination angle of the first inclined groove 112 is approximately 45°, that is, the angle between the first inclined groove 112 and the horizontal line is approximately 45°, thereby enabling the main push rod 110 to have approximately the same movement speed as the main tongue 103.

[0102] In a preferred embodiment, the upper end of the first inclined groove 112 has a vertical portion, so that when the electric lock is in the locked state, the main tongue guide post 105 can be located in the vertical portion, thereby preventing the main tongue 103 from pushing the main push rod 110 to move, that is, preventing the electric lock from being opened improperly, making the electric lock safer.

[0103] The power-gathering module 102 is provided with a power-gathering module guide post 106, which is slidably disposed in the second inclined groove 113. The second inclined groove 113 is inclined upward in the direction from left to right. In this disclosure, the inclination angle of the second inclined groove 113 is approximately 60-70°, that is, the angle between the second inclined groove 113 and the horizontal line is approximately 60-70°. This results in the power-gathering module 102 having a slower movement speed compared to the main push rod 110, and also allows the second inclined groove 113 to be shorter.

[0104] like Figure 6 As shown, the lock body 100 of this disclosure also includes a first rotating shaft 120, which is rotatably disposed on the housing 101. In one embodiment, the first rotating shaft 120 has a square central hole, thereby enabling the first rotating shaft 120 to be connected to an external handle, and the first rotating shaft 120 to be rotated by operating the external handle.

[0105] A first shift fork 107 is rotatably mounted on the first rotating shaft 120. The first shift fork 107 cooperates with the main push rod 110 and can drive the main push rod 110 to move upward, thereby realizing the unlocking operation.

[0106] At this time, the lock body 100 also includes a clutch, which is used to control the separation and engagement of the first rotating shaft 120 and the first shift fork 107. When the first rotating shaft 120 is engaged with the first shift fork 107, the first rotating shaft 120 and the first shift fork 107 rotate synchronously. When the first rotating shaft 120 is disengaged from the first shift fork 107, the first shift fork 107 can rotate relative to the first rotating shaft 120.

[0107] In other words, when the first rotating shaft 120 is separated from the first shift fork 107, operating the external handle will not cause the first shift fork 107 to move, and the electric lock will not open. On the other hand, when the first rotating shaft 120 is engaged with the first shift fork 107, operating the external handle will cause the first shift fork 107 to rotate synchronously, thereby pushing the main push rod 110 upward through the first shift fork 107, thus unlocking the electric lock.

[0108] Figure 10This is a schematic diagram of the engagement state of the first rotating shaft and the first shift fork according to one embodiment of the present disclosure.

[0109] In one embodiment, at least a portion of the first shift fork 107 is sleeved on the first rotating shaft 120; wherein, the first rotating shaft 120 has a groove, and the portion of the first shift fork 107 sleeved on the first rotating shaft 120 has a hole, and the clutch includes a pin 108. When the pin 108 passes through the hole and is inserted into the groove, the first rotating shaft 120 and the first shift fork 107 are in an engaged state, and when the pin 108 leaves the groove, the first rotating shaft 120 and the first shift fork 107 are in a disengaged state.

[0110] See again Figure 6 The lock body 100 also includes an electric drive device 109, which is electrically connected to the power supply module 102. When power is supplied to the power supply module, the electric drive device 109 is activated and can cause the clutch to operate. Furthermore, it can cause the first rotating shaft 120 to separate and engage with the first shift fork 107.

[0111] In one embodiment, the electric drive device 109 can be a linear motion component such as an electromagnet, an electromagnetic push rod, or an electric cylinder. In one embodiment, the lock body 100 includes a rotating rod 181, which is rotatably disposed on the housing 101. For example, the middle part of the rotating rod 181 is hinged to the housing 101, and the rotation axis of the rotating rod 181 is in the front-back direction. Accordingly, when the electric drive device 109 is activated, it can push the upper end of the rotating rod 181 to move to the left, and correspondingly, the lower end of the rotating rod 181 will move to the right, causing the pin 108 to move to the right, thereby engaging the first rotating shaft 120 and the first fork 107. That is, one end of the rotating rod 181 is in contact with the pin 108. When the rotating rod 181 is pushed and rotated by the electric drive device 109, the rotating rod 181 can push the pin 108 to translate and insert it into the groove of the first rotating shaft 120.

[0112] At this time, the outer handle can be operated to rotate along the rotation axis of the first rotating shaft 120. The groove of the first rotating shaft 120 can then engage the pin 108, preventing the pin 108 from leaving the groove. When the outer handle is rotated to a certain angle, the main latch 103, the power supply module 102, and the oblique latch 182 all retract into the housing 101, thereby unlocking the electric lock.

[0113] When the electric lock is unlocked, the user keeps the outer handle in the unlocked state and pushes the door open. At this time, the trigger 140 is reset under the action of the spring force, that is, at least part of the trigger 140 is located outside the housing 101. At this time, the trigger 140 will restrict the position of the main push rod 110, so that the main push rod 140 cannot move downward and the electric lock will always be in the unlocked state.

[0114] When the electronic lock is opened, the user can release the outer handle, which will reset under the action of a coil spring, etc. The pin 108 will also reset under the action of a spring fitted onto it and move away from the groove of the first rotating shaft 120. The first shift fork 107 will also reset under the action of a coil spring, etc. Meanwhile, to prevent excessive reset of the first rotating shaft 120 and the first shift fork 107, a limit block or similar structure can be provided within the housing 101. The structure and position of this limit block already exist in the prior art and will not be described in detail here.

[0115] On the other hand, the electronically controlled lock disclosed herein can also be unlocked from the inside. Specifically, the lock body 100 further includes a second rotating shaft 130, which may have the same rotation axis as the first rotating shaft 120, and the second rotating shaft 130 also has a square central hole. Accordingly, an inner handle can be installed on the second rotating shaft 130.

[0116] Figure 11 This is a schematic diagram of the engagement state of the second rotating shaft and the first shift fork according to one embodiment of the present disclosure.

[0117] like Figure 11 As shown, the second rotating shaft 130 can engage with the first shift fork 107, allowing the second rotating shaft 130 to rotate synchronously with the first shift fork 107. In other words, when the user is indoors, they can directly rotate the inner handle, causing the second rotating shaft 130 to rotate. At this time, the first shift fork 107 will rotate, causing the main push rod 110 to move upward, thus unlocking the device.

[0118] like Figure 10 and Figure 11As shown, a second shift fork 121 is fixedly disposed on the first rotating shaft 120. For example, the second shift fork 121 is integrally formed with the first rotating shaft 120. The lock body 100 also includes a latch assembly. The second shift fork 121 cooperates with the latch assembly. When the first rotating shaft 120 rotates, it can drive at least a portion of the latch 182 of the latch assembly to retract into the housing 101. In this disclosure, a third shift fork 131 can also be fixedly disposed on the second rotating shaft 130. For example, the second rotating shaft 130 and the third shift fork 131 are integrally formed. Correspondingly, when the second rotating shaft 130 rotates, it can also drive at least a portion of the latch 182 of the latch assembly to retract into the housing 101.

[0119] In one specific implementation, the latch assembly further includes a connecting rod 183 and a guide block 184. One end of the connecting rod 183 is connected to the latch 182, and the other end is connected to the guide block 184. A guide hole is provided on the housing 101, and the guide block 184 is slidably disposed within the guide hole, which restricts its position. Correspondingly, the second fork 121 and the third fork 131 are operably connected to the guide block 184, thereby driving the guide block 184 to move, and thus causing the latch 182 to move left and right. In a preferred embodiment, the guide block 184 can be subjected to an elastic force by an elastic component, causing the guide block 184 to tend to move to the right. Therefore, under normal conditions, the latch 182 can be at least partially located outside the housing 101.

[0120] Figure 12 This is a schematic diagram of the structure of a trigger 140 according to one embodiment of the present disclosure.

[0121] In this disclosure, such as Figures 5 to 8 As shown, the lock body 100 also includes a trigger 140. When the electric lock is in the unlocked state, the trigger 140 is used to hold the main push rod 110 in a first position; when the electric lock is in the locked state, the trigger 140 is used to hold the main push rod 110 in a second position; wherein, when the trigger 140 is triggered, the main push rod 110 is allowed to move from the first position to the second position, wherein the first position is higher than the second position.

[0122] Specifically, the trigger 140 may include a support frame 141, a roller 142, a connector 143, and a guide 144.

[0123] The support frame 141 is slidably disposed on the housing 101, and the roller 142 is rotatably disposed on the support frame 141 and can extend at least partially outside the housing 101, so that the roller 142 can engage with the trigger 240 and be fired by the trigger 240. That is, when the door is closed, the trigger 240 can push the roller 142 to move, causing the support frame 141 to move to the left, and further causing the connector 143 and guide 144 connected to the support frame 141 to move to the left, thereby causing the guide 144 to release the main push rod 110.

[0124] That is, one end of the connector 143 is connected to the support frame 141, and the other end of the connector 143 is connected to the guide member 144. The housing 101 is provided with a guide groove, and the guide member 144 can be slidably disposed in the guide groove, and the position of the guide member 144 is restricted by the guide groove.

[0125] In a preferred embodiment, the support frame 141 can be subjected to an elastic force by an elastic member, thereby giving the support frame 141 a tendency to move to the right, so that, under normal conditions, the roller 142 can be located at least partially outside the housing 101.

[0126] In this disclosure, the lock body 100 further includes an elastic element (not shown in the figure), through which the main push rod 110 moves from a first position to a second position by the pulling force provided by the elastic element. That is, the main push rod 110 can automatically lock by the downward pulling force provided by the elastic element.

[0127] In this disclosure, the lock body further includes a safety bolt 150, which has a first position and a second position. When the electronic lock is in the unlocked state and the safety bolt 150 is in the first position, the safety bolt 150 restricts the downward movement of the main push rod 110, thereby keeping the electronic lock in the unlocked state. In this state, the electronic lock is not affected by the trigger 140; that is, even if the trigger 140 is triggered, the electronic lock will not lock. Correspondingly, when the safety bolt 150 is in the second position, the main push rod 110 is allowed to move downward, meaning that the electronic lock is allowed to lock at this time.

[0128] When the electronic lock is in the locked state and the safety bolt 150 is in the first position, the safety bolt 150 restricts the upward movement of the main push rod 110, thereby keeping the electronic lock 150 in the locked state. When the safety bolt 150 is in the second position, it allows the main push rod 110 to move upward.

[0129] In this disclosure, the lock body also includes a lock cylinder (not shown in the figure). When the lock cylinder rotates, it can push the lower end of the rotating rod 181 to move and cause the pin 108 to move, further causing the first fork 107 and the first rotating shaft 120 to engage, so that the unlocking operation can be realized by operating the outer handle, and the key unlocking function can be realized.

[0130] In a preferred embodiment, the lock body further includes a top rod 185 and a bottom rod 186, wherein both the top rod 185 and the bottom rod 186 are connected to the main bolt 103. When the main bolt 103 moves to the right, that is, when the electric lock is in the locked state, the top rod 185 and the bottom rod 186 extend. Thus, the electric lock of this disclosure can be applied to security doors and form a top and bottom lock structure, thereby further improving the security performance of the electric lock of this disclosure.

[0131] On the other hand, when the main tongue 103 moves to the left and puts the electric lock in the unlocked state, the top rod 185 and the bottom rod 186 retract.

[0132] In this disclosure, the electronic lock also includes a locking status detection device. For example, the locking status detection device may include a magnetic sensor (e.g., a reed switch) and a magnet. The magnetic sensor may be disposed on the guard plate 200, and the magnet may be disposed on the housing 101. Thus, when the positions of the magnet and the magnetic sensor are aligned, that is, after the door is closed, the magnet and the magnetic sensor are close together, and the magnetic sensor outputs a closing signal to realize the function of door magnetic signal output.

[0133] Considering the operating environment of the electronic lock, such as when it is installed on a wooden door, the door may deform, creating a gap, or there may be a gap at the location where the electronic lock is installed. In this case, gap compensation is required. In this disclosure, the trigger 240 may further include an elastic body, which applies a pushing force to the frame 241, so that after the rolling element 242 is reset, it is at least partially located outside the guard plate 200. Thus, the position of the frame 241 relative to the guard plate 200 can be adjusted by the elastic body. Therefore, when the door is closed, the rolling element 242 of the trigger 240 will make pressure contact with the roller 142 of the trigger 140, i.e., they can "push" each other. Thus, the lock body and the guard plate are not displaced by ordinary forces (such as wind force), achieving gap compensation.

[0134] The following is a brief description of the working process of the electronically controlled lock disclosed herein.

[0135] When the door closes, the trigger collides with the firing mechanism. The trigger is squeezed and moves to the left, and its guide moves to the left and moves out of the slot of the main push rod. Then the main push rod is released from the limit of the trigger and moves downward under the pull of the spring. It then slides to the right and pushes out the main tongue and the power supply module. The extension of the main tongue drives the top rod and the bottom rod to push up and down to the right respectively, realizing the automatic locking function when the door is closed. At the same time, the power supply module is inserted into the power supply module.

[0136] In this disclosure, when the electric lock is in the unlocked state, the safety bolt 150 can be moved between the first and second positions by the toggle button 189, that is, moved in the left and right direction, so that the safety bolt is moved to the right and locked in the slot on the side of the main push rod, so that the main push rod cannot move downward under any circumstances, keeping the lock body in the unlocked state and realizing the setting of preventing automatic locking indoors.

[0137] Similarly, when the lock body is in the locked state, the safety bolt is moved to the right and locks the slot on the side of the main push rod, so that the main push rod cannot move upward under any circumstances, thus locking the lock body in the locked state. This is the working principle of an indoor safety lock.

[0138] During the unlocking process, when the main push rod moves upward to a certain position, the trigger moves to the right under the influence of spring tension until it jams the main push rod's slot, locking the lock body in the unlocked state.

[0139] In a preferred embodiment, the power supply module may include a power plug and power contacts disposed on the power plug. The power plug may be made of materials such as nylon, and the power contacts may be made of materials such as pure copper. When the power supply module is inserted into the power supply module, the power contacts can connect to the power supply terminal and conduct electricity. When unlocking is required, the access control system can supply power to the power contacts through the power supply terminal to achieve unlocking. After unlocking, the power contacts and the power supply terminal are physically disconnected. Therefore, the power supply time of the lock body disclosed herein is from the moment the access control system outputs the unlock signal to the moment of unlocking (i.e., the moment the power supply module retracts and separates from the power supply module). Compared with other types of electronic locks, this method has the shortest power supply time and the lowest energy consumption.

[0140] Moreover, the power source of the electric lock disclosed herein is on one side of the door cover. The door cover is usually installed at the door frame, which is closest to the electronic access control equipment. No other cable passing device is required during wiring, and the door body does not need to be damaged. Compared with other types of electric locks, this reduces the complexity of overall wiring.
