Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of locks, and in particular to a multifunctional rotating part, an electronic unlocking mechanism and an anti-mistake electric control lock. Background Art
[0002] At present, electric locks usually use a lock hook and a lock bolt to lock and unlock, and the movement of the lock bolt is controlled by an electric drive element. When unlocking, a card reader is needed to send an unlocking command to the electric lock to control the movement of the lock bolt to achieve the purpose of unlocking. In order to prevent the lock bolt from moving, a spring is usually set between the lock bolt and the lock body. First, it can prevent the lock bolt from moving on its own. Second, when the electric lock is unlocked and then locked, the spring can provide elastic force to the lock bolt, so that the lock bolt moves toward the lock hook and engages with the lock hook to achieve automatic locking.
[0003] Although the above-mentioned electric control lock can use the elastic force of the spring to ensure that the lock bolt cannot move by itself within a certain limit, the following problem still exists: when the force provided to the lock bolt by external vibration is exactly the direction of movement of the lock bolt when unlocked, and is greater than the elastic force of the spring, the lock bolt will move under the action of the external force and be unlocked by mistake. Summary of the invention
[0004] The first object of the present invention is to provide a multifunctional rotating part, which switches the driving function and the limiting function by rotating, provides driving force when the part needs to move, and provides mechanical limiting effect when the part needs to limit movement.
[0005] In order to achieve the purpose of the present invention, the present invention adopts the following technical solutions:
[0006] A multifunctional rotating part, used for driving / limiting the movement of a first component, comprises a connecting part, a driving part and a limiting part; the connecting part rotates between a first position and a second position under the action of an external force, driving the driving part and the limiting part to rotate; when the connecting part rotates from the first position to the second position, the limiting part releases the limit on the first component, and the driving part drives the first component to move.
[0007] As a specific embodiment, the driving portion includes a first protrusion arranged along an axis perpendicular to the connecting portion; the limiting portion includes a second protrusion arranged along an axis perpendicular to the connecting portion, and the angle between the second protrusion and the first protrusion is greater than 0° and less than 180°; when the connecting portion rotates from a first position to a second position, the first protrusion rotates from a position away from the first component to a position in contact with the first component, pushing the first component to move; when the connecting portion rotates from a first position to a second position, the second protrusion rotates from a position away from the direction in which the first protrusion pushes the first component to a position close to the direction in which the first protrusion pushes the first component to release the limit on the first component.
[0008] As a specific implementation, the angle between the second protrusion and the first protrusion is equal to 90°.
[0009] As a specific embodiment, a first recess for accommodating the multifunctional rotating part is opened on the side wall of the first component; the first recess includes a first inner side wall and a second inner side wall arranged opposite to each other, and the second inner side wall pushes the moving direction of the first component away from the first protrusion compared to the first inner side wall; when the connecting part rotates from the first orientation to the second orientation, the outer side wall of the first protrusion rotates from a position away from the first inner side wall to a position in contact with the first inner side wall, pushing the first inner side wall to move; when the connecting part rotates from the first orientation to the second orientation, the outer side wall of the second protrusion rotates from a position close to the second inner side wall to a position away from the second inner side wall.
[0010] As a specific implementation, when the connecting portion is rotated to the first orientation, the shortest distance between the second protrusion and the second inner side wall is greater than or equal to 0, and is less than the distance that the first protrusion pushes the first component to move.
[0011] As a specific embodiment, the multifunctional rotating part also includes a positioning portion; when the connecting portion moves to the first position or the second position, the positioning portion limits the connecting portion from continuing to rotate; the positioning portion includes the first protrusion and the second protrusion; when the connecting portion rotates to the first position, the first protrusion rotates to a position that limits the first protrusion from continuing to rotate or contacts a travel switch that controls the rotation of the connecting portion; when the connecting portion rotates to the second position, the second protrusion rotates to a position that limits the second protrusion from continuing to rotate or contacts another travel switch that controls the rotation of the connecting portion.
[0012] Furthermore, the multifunctional rotating member also includes a positioning portion; when the connecting portion moves to the first position or the second position, the positioning portion restricts the connecting portion from continuing to rotate.
[0013] As a specific embodiment, the positioning portion includes a third protrusion arranged along an axial direction parallel to the connecting portion. When the connecting portion moves to a first position, the third protrusion rotates to a position that limits the further rotation of the third protrusion or rotates to contact a travel switch that controls the rotation of the connecting portion. When the connecting portion moves to a second position, the third protrusion rotates to another position that limits the further rotation of the third protrusion or rotates to contact another travel switch that controls the rotation of the connecting portion.
[0014] As a specific implementation, the connecting portion is provided with a slot / hole along the axial direction to cooperate with the driving portion; the driving portion is used to drive the connecting portion to rotate.
[0015] The second purpose of the present invention is to provide an electronic unlocking mechanism, which switches the driving function and the limiting function of the multifunctional rotating part by rotation. When the lock bolt needs to move, the driving part provides the driving force, and when the lock bolt needs to limit the movement, the limiting part provides the mechanical limiting effect.
[0016] In order to achieve the second purpose of the present invention, the present invention adopts the following technical solution:
[0017] An electronic unlocking and locking mechanism comprises a motor, a lock bolt and the above-mentioned multifunctional rotating member; the output shaft of the motor is connected to the connecting part to drive the connecting part to rotate; the lock bolt adopts the above-mentioned first component; when the electronic unlocking and locking mechanism is locked, the multifunctional rotating member limits the movement of the lock bolt through the limiting part; when the electronic unlocking and locking mechanism is unlocked, the multifunctional rotating member drives the lock bolt to move through the driving part.
[0018] Furthermore, the electronic unlocking mechanism also includes a first elastic element; when the connecting part rotates from a first position to a second position, the driving part drives the locking bolt to move toward the first elastic element, and the first elastic element is in a compressed state; when the connecting part rotates from the second position to the first position, the first elastic element pushes the locking bolt to move in a direction away from the first elastic element through elastic force.
[0019] The third purpose of the present invention is to provide an anti-misoperation electric lock, which switches the driving function and the limiting function of the multifunctional rotating part by rotating. When the electric lock needs to be unlocked, the limiting part of the lock is released, and the driving part provides a driving force to drive the lock bolt to move to complete the unlocking. When the electric lock needs to be locked, the first elastic element provides a driving force in the opposite direction to the lock bolt to complete the locking, and the limiting part limits the lock bolt to prevent the lock bolt from moving under the action of external force and then being mislocked.
[0020] In order to achieve the third object of the present invention, the present invention adopts the following technical solution:
[0021] A misoperation-proof electric lock, characterized in that it comprises a lock hook, a lock body, an electric control module and the above-mentioned electronic unlocking mechanism; the lock hook is movably mounted on the lock body and can be in a locked position or an unlocked position, and the portion of the lock hook that cooperates with the lock body is provided with at least one limiting groove; the electronic unlocking mechanism is mounted in the lock body to limit the movement of the lock hook or release the limit on the lock hook; the electric control module is mounted in the lock body to control the action of the electronic unlocking mechanism; when the lock hook is in the locked position, the lock bolt is opposite to the limiting groove and is snapped into the limiting groove under the elastic force of the first elastic element; when the connecting part is driven by the motor to rotate from a first position to a second position, the limiting part releases the limit on the lock bolt, and the driving part drives the lock bolt to move toward the first elastic element so that the lock bolt moves out of the limiting groove.
[0022] Beneficial effects of the present invention:
[0023] The multifunctional rotating member of the present invention switches the driving function and the limiting function by rotation, provides a driving force when the first component needs to move, and provides a mechanical limiting function when the first component needs to limit movement, so as to prevent the first component from moving under the action of an external force or moving a distance exceeding a set distance when the movement needs to be limited. The present invention prevents the first component from moving under the action of an external force beyond the distance pushed by the first protrusion to move the first component by setting the shortest distance between the second protrusion and the second inner side wall of the first recess to be greater than or equal to 0 and less than the distance pushed by the first protrusion to move the first component, so that the limiting part loses the limiting function. The multifunctional rotating member of the present invention controls the first component to stop rotating after rotating to the required angle through the positioning part. The electronic unlocking mechanism of the present invention switches the driving function and the limiting function of the multifunctional rotating member by rotation, so that the driving force is provided by the driving part when the lock bolt needs to move, and the mechanical limiting function is provided by the limiting part when the lock bolt needs to limit movement, so as to prevent the lock bolt from moving under the action of an external force or moving a distance exceeding a set distance when the movement needs to be limited. The anti-error electric lock of the present invention switches the driving function and the limiting function of the multifunctional rotating part by rotation. When the electric lock needs to be unlocked, the limiting part on the lock bolt is released, and the driving part provides a driving force to drive the lock bolt to move to complete the unlocking. When the electric lock needs to be locked, the first elastic element provides a driving force in the opposite direction to the lock bolt to complete the locking, and the limiting part limits the lock bolt to prevent the lock bolt from being moved under the action of external force and then unlocked by mistake.

[0044] like Figure 5As shown in 8 and 10, the multifunctional rotating member 32 includes a connecting portion 321, a driving portion 322, a limiting portion 323 and a positioning portion 324; the connecting portion 321 includes a first assembly hole 3211 that cooperates with the output shaft of the motor 31; the driving portion 322 includes a first protrusion 3221 arranged along an axial direction perpendicular to the first assembly hole 3211, the limiting portion 323 includes a second protrusion 3231 arranged along an axial direction perpendicular to the first assembly hole 3211, and the positioning portion 324 includes a third protrusion 3241 arranged along an axial direction parallel to the first assembly hole 3211 and outside the first assembly hole 3211; the output shaft of the motor 31 cooperates with the first assembly hole 3211 through the first opening 1212 to drive Connecting portion 321; driven by the motor 31, the connecting portion 321 rotates between a first position (corresponding to the locked position of the free end 22 of the lock hook) and a second position (corresponding to the unlocked position of the free end 22 of the lock hook), thereby driving the driving portion 322, the limiting portion 323 and the positioning portion 324 to rotate; when the connecting portion 321 rotates from the first position to the second position, the limiting portion 323 rotates from a position that restricts the movement of the lock bolt 33 to a position that releases the restriction on the lock bolt 33, and the driving portion 322 rotates from a position that stops driving the lock bolt 33 to move to a position that drives the lock bolt 33 to move; when the connecting portion 321 rotates to the first position or the second position, the positioning portion 324 restricts the connecting portion 321 from continuing to rotate.
[0045] like Fig. 9 As shown, the first recess 331 includes a first inner side wall 3311 and a second inner side wall 3312 arranged perpendicular to the axial direction; Figure 3 As shown in FIGS. 4 and 5, when the connecting portion 321 rotates to the first position, the first protrusion 3221 faces a direction staggered from the second inner wall 3312, and the lock bolt 33 is pushed by the elastic force of the first elastic element 34 to snap into the first limiting groove 221 on the free end 22 of the lock hook, and the anti-mistake electric control lock is in a locked state; Figure 6 As shown in Figures 7 and 8, when the connecting portion 321 rotates to the second position, the first protrusion 3221 rotates to contact the second inner wall 3312 under the drive of the connecting portion 321, and the locking bolt 33 is pushed toward the first elastic element 34 by pushing the first inner wall 3311, so that the end of the locking bolt 33 away from the first elastic element 34 moves out of the first limiting groove 221, and the free end 22 of the locking hook moves from the locked position to the unlocked position, thereby achieving unlocking.
[0046] like Fig.10 As shown, in this embodiment, the first protrusion 3221 and the second protrusion 3231 are arranged at an angle of 90°; Figure 3As shown, when the connecting portion 321 is rotated to the first position, the second protrusion 3231 contacts or transitionally fits with the second inner wall 3312 of the locking bolt 33 (i.e., the second protrusion 3231 and the second inner wall 3312 are arranged relative to each other with a certain gap, and the gap is smaller than the distance that allows the locking bolt 33 to move out to the point where the free end 22 of the lock hook can move to unlock, i.e., the shortest distance between the second protrusion 3231 and the second inner wall 3312 is greater than or equal to 0, and is smaller than the distance that the first protrusion 3221 pushes the locking bolt 33 to move), and the second protrusion 3231 is arranged relative to the second inner wall 3312 with a certain gap, and the gap is smaller than the distance that allows the locking bolt 33 to move out to the point where the free end 22 of the lock hook can move to unlock, i.e., the shortest distance between the second protrusion 3231 and the second inner wall 3312 is greater than or equal to 0, and is smaller than the distance that the first protrusion 3221 pushes the locking bolt 33 to move). The movement of the lock bolt 33 when the anti-error electric control lock is in the locked state is limited. Even if the direction of the external force is greater than the elastic force of the first elastic element 34, the lock bolt 33 cannot move to the position where the lock hook free end 22 can move due to the limiting effect of the second protrusion 3231, thereby preventing erroneous unlocking. When the connecting portion 321 rotates to the second orientation, the second protrusion 3231 rotates to a direction staggered with the second inner side wall 3312 under the drive of the connecting portion 321, thereby releasing the limiting effect on the second inner side wall 3312, thereby releasing the restriction on the movement of the lock bolt 33.
[0047] In other embodiments, the included angle between the first protrusion 3221 and the second protrusion 3231 may be other included angles greater than 0° and less than 180°.

[0049] like Figure 3 As shown in Figures 5, 6, and 8, in the present embodiment, the anti-error electric control lock also includes a second elastic element 6; the second elastic element 6 is installed on the lower left side of the mounting seat 12, the bottom is against the mounting seat 12, and the top is connected with a sliding member 61; when the free end 22 of the lock hook is in the locked position, the free end 22 of the lock hook contacts the sliding member 61, and pressure is applied to the second elastic element 6 through the sliding member 61, so that the second elastic element 6 is in a compressed state; when the lock bolt 33 moves out of the first limiting groove 221 and releases the restriction on the free end 22 of the lock hook, the sliding member 61 moves under the elastic force of the second elastic element 6, pushing the free end 22 of the lock hook from the locked position to the unlocked position.

[0052] like Figure 2 As shown, the lock shell cover 112 includes an inner cover 1121 and an outer cover 1122. The inner cover 1121 includes a first cover plate 11211 and a second cover plate 11212. The first cover plate 11211 blocks the opening of the first installation chamber 121, and the second cover plate 11212 blocks the openings of the second installation chamber 122 and the third installation chamber 123. The outer cover 1122 is installed on the outside of the inner cover 1121.
[0053] like Figure 3 ,6, the anti-theft mechanism 4 includes a first screw 41 and a joint 42, the joint 42 is arranged on the inner wall of the outer cover 114, and a first mounting hole 421 is opened on the joint 42 (such as Figure 2 The top of the mounting seat 12 is provided with a second mounting hole 124 (as shown) which leads from the top to the third mounting chamber 123. Fig.11 As shown); the first screw 41 passes through the second mounting hole 124 on the mounting seat 12 and the first mounting hole 421 on the outer cover 114 in sequence, and the outer cover 114 is fixedly connected to the mounting seat 12; after the outer cover 114 is fixedly connected to the mounting seat 12, the fixed end 21 of the lock hook passes through the lock hole on the lock shell 111, extends into the first mounting hole 421 in the mounting seat 12, and covers the first screw 41, which can well fix the electronic unlocking mechanism 3 and the electric control module in the mounting seat 12, thereby improving the anti-disassembly and anti-theft performance of the anti-mistake electric control lock.
[0054] like Figure 2 As shown, the anti-error electric control lock also includes a nameplate 7 attached to the outer side wall of the outer cover 114, and the nameplate 7 records some technical data of the manufacturer and rated conditions for the user to correctly use the anti-error electric control lock.
[0055] like Figures 1 to 8 As described above, a waterproof cover 8 is provided at the connection between the free end 22 of the lock hook and the lock body 1 to improve the waterproof performance of the anti-mistake electric control lock.

[0057] In this embodiment, the wireless charging receiving circuit includes an NFC antenna, a resonant circuit, and a rectifier circuit connected in sequence; the NFC antenna receives electromagnetic waves sent by the NFC card reader, and sends the electromagnetic waves to the resonant circuit, the resonant circuit resonates with the electromagnetic waves, and outputs high-frequency current to the rectifier circuit; the rectifier circuit converts the high-frequency current output by the resonant circuit into direct current energy and stores it in the energy storage circuit.
[0058] In this embodiment, the specific operation of the NFC card reader to implement unlocking is as follows:
[0059] When unlocking, the unlocker transmits energy to the wireless charging receiving circuit wirelessly, and transmits the unlocking instruction to the communication circuit. After receiving the energy, the wireless charging receiving circuit powers the control circuit and the motor. The communication circuit sends the unlocking instruction to the control circuit, and the control circuit outputs a control signal to the motor 31, which controls the motor 31 to rotate, driving the connecting part 321 to rotate from the first position to the second position, and the lock bolt 33 releases the limit on the free end 22 of the lock hook. The free end 22 of the lock hook moves from the locked position to the unlocked position under the elastic force of the second elastic element 6, thereby achieving unlocking.
[0060] In this embodiment, after the motor 31 controls the smart lock to complete the unlocking operation, the motor 31 automatically resets and rotates from the second position back to the first position, pressing the lock hook 33 downward, and the lock bolt 33 is snapped into the first limiting groove 221 on the free end 22 of the lock hook to complete the locking.
