Description

Technical Field

[0001] The present invention relates to the technical field of locks, and in particular to an unlocking drive mechanism, a lock and a handle lock. Background Art

[0002] In a lock, a drive mechanism is used to drive an unlocking member to move between an unlocking position and a locking position to achieve unlocking or locking, and an elastic member is usually used to provide an elastic force acting on the unlocking member. In the related art, when a lock is struck or violently vibrated, the unlocking member may move, thereby causing the lock to fail and affecting the reliability of the lock. Summary of the invention

[0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To this end, the purpose of the present invention is to provide an unlocking drive mechanism, a lock and a handle lock.

[0004] To achieve the above objectives, in a first aspect, an unlocking drive mechanism according to an embodiment of the present invention includes:

[0005] An unlocking seat, wherein a stopper is provided on the unlocking seat;

[0006] A coil spring, wherein the coil spring is fixed relative to the unlocking seat, an end of the coil spring abuts against the stopper, and the stopper is configured to apply an unbalanced force on the circumference of the end of the coil spring to tilt the coil of the coil spring;

[0007] A pivot shaft, which can pivot around its own axis and is inserted into the coil spring. A push pin extending in the radial direction is provided on the pivot shaft, and the push pin is located between two adjacent spring coils on the coil spring.

[0008] According to the unlocking drive mechanism of the present invention, when the pushing pin on the pivot shaft rotates with the pivot shaft, the coil spring can be pushed, and then the coil spring is used to push the unlocking seat to move, thereby realizing unlocking or locking. Since the stop portion on the unlocking seat is constructed to apply an unbalanced force in the circumferential direction of the end of the coil spring to tilt the spring coil of the coil spring, when the inclined ring cooperates with the pushing pin, the rotation of the pushing pin needs to overcome a large resistance from the spring coil. In this way, when the lock is hit or vibrated violently, the rotation of the pushing pin needs to overcome a large resistance from the spring coil. Therefore, the pivot shaft and the pushing pin thereon are not easy to rotate, and the unlocking seat is not easy to move, thereby keeping the lock in a locked state, thereby improving the reliability of the lock.

[0009] According to one embodiment of the present invention, it also includes a driving device, which is connected to the pivot shaft and is used to drive the pivot shaft and the pushing pin to rotate, so that the pushing pin pushes the unlocking seat to move through the coil spring.

[0010] According to an embodiment of the present invention, the stopper abuts against a local position of the end of the coil spring.

[0011] According to an embodiment of the present invention, the stopper has an inclined surface, and the inclined surface abuts against the end of the coil spring.

[0012] According to one embodiment of the present invention, there are two stop parts, one end of the coil spring abuts against one of the two stop parts, and the other end of the coil spring abuts against the other of the two stop parts, and when the two ends of the coil spring are respectively subjected to the forces applied by the two stop parts, the spring coils of the coil spring have the same inclination direction.

[0013] According to one embodiment of the present invention, a receiving groove is provided on the unlocking seat, the receiving groove has two opposite end walls, the stop portion is provided on the end walls and protrudes into the receiving groove, the coil spring is accommodated in the receiving groove, and the end of the coil spring abuts against the stop portion.

[0014] According to one embodiment of the present invention, the accommodating groove also has a side wall, the side wall is provided with a positioning groove, and the positioning groove extends along the axial direction of the coil spring; the two ends of the coil spring have positioning feet, and the positioning feet are clamped in the positioning groove to fix the coil spring and the unlocking seat relative to each other in the circumferential direction.

[0015] According to an embodiment of the present invention, the driving device is a knob or a motor.

[0016] In a second aspect, the present invention provides a lock having the unlocking drive mechanism as described above.

[0017] The lock according to the present invention has the unlocking drive mechanism, which can improve the reliability of the lock.

[0018] In a third aspect, the present invention provides a handle lock, comprising:

[0019] A clutch seat, the clutch seat having an axial locking hole and a radial pin hole communicating with the axial shaft hole;

[0020] A handle, the handle comprising a pivoting portion and a handle portion, the pivoting portion being sleeved outside the clutch seat and being pivotable relative to the clutch seat, and an inner wall of the pivoting portion being provided with an axially extending slot, the handle portion being connected to the pivoting portion for user operation;

[0021] An elastic locking pin, wherein the elastic locking pin is arranged in the radial pin hole, and one end of the elastic locking pin is abutted in the clamping groove;

[0022] The unlocking drive mechanism as described above is arranged in the handle, and when the pivot shaft pivots, the coil spring pushes the unlocking seat to enter or exit the axial locking hole;

[0023] When the unlocking seat enters the axial locking hole, the other end of the elastic locking pin is stopped by the unlocking seat, thereby locking the handle and the clutch seat relative to each other; when the unlocking seat exits the axial locking hole, the unlocking seat releases the elastic locking pin so that the handle and the clutch seat can pivot relative to each other.

[0024] The handle lock according to the present invention has the above-mentioned unlocking drive mechanism. When the lock is hit or violently vibrated, the rotation of the push pin needs to overcome the greater resistance from the spring coil. Therefore, the pivot shaft and the push pin thereon are not easy to rotate, and the unlocking seat is not easy to disengage from the axial lock hole, thereby keeping the lock in a locked state, thereby improving the reliability of the handle lock.

[0066] The unlocking drive mechanism, the lock and the handle lock according to the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0067] Reference Figures 1 to 5 As shown, the unlocking drive mechanism provided according to the embodiment of the present invention can be applied to but not limited to locks. The unlocking drive mechanism includes an unlocking seat 10 , a coil spring 20 and a pivot shaft 30 .

[0068] Specifically, the unlocking seat 10 can be used to unlock or lock a locked component in a lock, and the locked component can be a lock pin or other components in the lock. A stopper 101 is provided on the unlocking seat 10 .

[0069] The coil spring 20 is relatively fixed to the unlocking seat 10 , and the end of the coil spring 20 abuts against the stopper 101 . The stopper 101 is configured to apply an unbalanced force on the circumferential direction of the end of the coil spring 20 to tilt the coil of the coil spring 20 .

[0070] That is to say, on one hand, the coil spring 20 is relatively fixed to the unlocking seat 10, and when subjected to external force, the coil spring 20 and the unlocking seat 10 can move together, for example, when an axial force is applied to the coil spring 20, the unlocking seat 10 can be pushed to move axially by the coil spring 20. On the other hand, the coil spring 20 is not in a natural state on the unlocking seat 10, but in an unbalanced compression state, that is, the stopper 101 abuts against the end of the coil spring 20, and the force applied by the stopper 101 to the end of the coil spring 20 in the circumferential direction is unbalanced. Due to the unbalanced force applied to the end of the coil spring 20, the coil spring 20 is compressed differently at different circumferential positions, causing the coil of the coil spring 20 to tilt to one side.

[0071] The pivot shaft 30 can pivot around its own axis and is inserted into the coil spring 20 . A push pin 301 extending in the radial direction is provided on the pivot shaft 30 . The push pin 301 is located between two adjacent coils on the coil spring 20 .

[0072] That is, the pivot shaft 30 can rotate relative to the coil spring 20 in the coil spring 20. Since the push pin 301 on the pivot shaft 30 is located between two adjacent coils on the coil spring 20, when the pivot shaft 30 rotates, the push pin 301 applies pressure to the coils, so that the coil spring 20 pushes the unlocking seat 10 to move, thereby unlocking or locking the locked part through the unlocking seat 10. For example, in the application of the lock, the unlocking seat 10 moves between the unlocking position and the locking position. In the unlocking position, the unlocking seat 10 is away from the locked part to unlock the locked part, and in the locking position, the unlocking member is close to the locked part to restrict the movement of the locked part to lock the locked part.

[0073] In the present application, since the spring coil of the coil spring 20 is tilted due to the uneven pressure applied by the stopper 101, when the pushing pin 301 on the pivot shaft 30 cooperates with the tilted spring coil, the resistance that needs to be overcome by the pushing pin 301 to push the tilted spring coil when it rotates increases. In other words, the spring coil is forced to tilt by the uneven pressure, thereby increasing the resistance that needs to be overcome by the pushing pin 301 when it rotates.

[0074] It should be noted that in various application scenarios of springs, the springs are usually compressed evenly, for example, both ends of the spring are against a plane that is perpendicular to the axis of the spring. In this way, both ends of the spring can receive a balanced force, so that the spring is compressed evenly (the spring coil is not forced to tilt), to ensure the reliability of the spring performance. Similarly, in the lock in the related art, in the unlocking mechanism using the spring to cooperate with the push pin 301 on the pivot shaft 30, both ends of the spring are also against the plane (such as Figure 7 As shown in the figure, the balanced compression state is maintained, and the resistance (F 2) that needs to be overcome when the push pin rotates is increased. In the present application, the traditional spring application method is broken through, and the spring coil of the spiral spring 20 is forced to tilt by applying an unbalanced force, thereby increasing the resistance (F 1, obviously, F 1 is greater than F 2) that needs to be overcome when the push pin 301 rotates. This resistance can prevent the unlocking seat 10 from moving due to vibration.

[0075] According to the unlocking drive mechanism of the present invention, when the pushing pin 301 on the pivot shaft 30 rotates with the pivot shaft 30, the coil spring 20 can be pushed, and then the coil spring 20 is used to push the unlocking seat 10 to move, thereby achieving unlocking or locking. Since the stopper 101 on the unlocking seat 10 is constructed to apply an unbalanced force on the circumferential direction of the end of the coil spring 20 to tilt the spring coil of the coil spring 20, when the inclined ring cooperates with the pushing pin 301, the rotation of the pushing pin 301 needs to overcome the greater resistance from the spring coil. In this way, when the lock is hit or vibrated violently, the rotation of the pushing pin 301 needs to overcome the greater resistance from the spring coil. Therefore, the pivot shaft 30 and the pushing pin 301 thereon are not easy to rotate, and the unlocking seat 10 is not easy to move, thereby keeping the lock in a locked state, thereby improving the reliability of the lock.

[0076] Reference Figures 1 to 5 As shown, in some embodiments of the present invention, a driving device 40 is further included, and the driving device 40 is connected to the pivot shaft 30 to drive the pivot shaft 30 and the push pin 301 to rotate, so that the push pin 301 pushes the unlocking seat 10 to move through the coil spring 20. In other words, the driving device 40 can drive the pivot shaft 30 to rotate, and then the pivot shaft 30 and the push pin 301 rotate to push the coil spring 20 and the unlocking seat 10 to move, so that the driving of the pivot shaft 30 is convenient.

[0077] Optionally, the driving device 40 is a knob or a motor. The knob can be manually operated by the user. When unlocking or locking is required, the user can operate the knob, such as the anti-lock knob on the door lock. The motor can realize automatic control operation, for example, the motor can be controlled to unlock or lock by using a password or biometric features such as fingerprints.

[0078] Reference Figure 4 As shown, in one embodiment of the present invention, the stopper 101 abuts against a local position of the end of the coil spring 20. For example, if the stopper 101 only applies force to a local position (e.g., the upper part in the circumferential direction) of the end of the coil spring 20, the local position on the coil spring 20 that is subjected to force will force the coil to tilt to one side (right side) due to the large amount of compression. For another example, if the stopper applies forces of different magnitudes to two different local positions of the end of the coil spring 20, due to the different forces applied to the two local positions, the different positions of the coil spring 20 will have different amounts of compression, which will also cause the coil to tilt to one side.

[0079] That is to say, in this embodiment, the stopper 101 is used to apply pressure to a local position of the coil spring 20, so that the end of the coil spring 20 is unevenly stressed and forced to tilt to one side. The structure is simple and the spring coil of the coil spring 20 can be tilted easily.

[0080] It is understandable that the stopper 101 can be formed into a relatively small boss structure (eg Figure 4 As shown in the figure, it is convenient to collide with the local position of the end of the coil spring 20, thereby generating a local force, thereby achieving the purpose of forcing the spring coil of the coil spring 20 to tilt.

[0081] Reference Figure 3 and Figure 5 As shown, in another embodiment of the present invention, the stopper 101 has an inclined surface S10 , and the inclined surface S10 abuts against the end of the coil spring 20 .

[0082] That is to say, in the present embodiment, the stopper 101 is configured as a wedge-shaped structure, and the end of the coil spring 20 directly abuts against the inclined surface S10 of the stopper 101. It can be understood that the end of the coil spring 20 can be locally abutted against the inclined surface S10 of the stopper 101, or the end of the coil spring 20 can completely abut against the inclined surface S10 of the stopper 101. In this way, the inclined surface S10 is used to achieve unbalanced compression of the end of the coil spring 20, thereby forcing the spring coil of the coil spring 20 to tilt. The structure is simple and can keep the coil spring 20 firmly installed.

[0083] It should be noted that the stopper 101 may be one (eg Figure 3 and Figure 4 As shown), it can also be two (as Figure 5 As shown in the figure, when there is only one stopper 101, one end of the coil spring 20 abuts against the stopper 101, and the other end of the coil spring 20 can abut against the unlocking seat 10, or be fixed to the unlocking seat 10 through other structural parts. By using one stopper 101, an unbalanced force can be applied to one end of the coil spring 20, so that one end of the coil spring 20 can be tilted.

[0084] When there are two stoppers 101, one end of the coil spring 20 abuts against one of the two stoppers 101, and the other end of the coil spring 20 abuts against the other of the two stoppers 101. When the two ends of the coil spring 20 are respectively subjected to the forces applied by the two stoppers 101, the coils of the coil spring 20 have the same inclination direction. Figure 5 In the example, one stopper 101 abuts against the upper portion of one end of the coil spring 20 , and the other stopper 101 abuts against the lower portion of the other end of the coil spring 20 , thereby ensuring that the coils of the coil spring 20 have the same inclination direction.

[0085] That is to say, by using two stop parts 101 to apply unbalanced forces to the two ends of the coil spring 20 respectively, the two ends of the coil spring 20 can be tilted, and the inclination directions of the two end ends of the coil spring 20 are the same. In this way, it can be ensured that the spring coil of the coil spring 20 has a larger inclination angle, and correspondingly, the resistance to the push pin 301 is greater.

[0086] Reference Figures 1 to 5 As shown, in one embodiment of the present invention, a receiving groove H10 is provided on the unlocking seat 10, and the receiving groove H10 has two opposite end walls H101, the stopper 101 is provided on the end wall H101 and protrudes into the receiving groove H10, the coil spring 20 is accommodated in the receiving groove H10, and the end of the coil spring 20 abuts against the stopper 101.

[0087] In this embodiment, a receiving groove H10 is provided on the unlocking seat 10, and the coil spring 20 is provided in the receiving groove H10, so as to facilitate the installation of the coil spring 20, and the two ends of the coil spring 20 are respectively abutted against the two end walls H101 of the receiving groove H10 or the stoppers on the end walls H101, so that the coil spring 20 can be installed reliably and form an inclined state.

[0088] Optionally, through holes are respectively provided on the two end walls H101 of the accommodating groove H10. The pivot shaft 30 passes through the through hole on one end wall H101, passes through the coil spring 20, and then passes out from the through hole on the other end wall H101. In this way, it is convenient to install the pivot shaft 30, and at the same time, it is also convenient to move the unlocking seat 10 along the axial direction of the pivot shaft 30.

[0089] Exemplarily, the accommodating groove H10 also has a side wall H102, and the side wall H102 is provided with a positioning groove H1021, and the positioning groove H1021 extends along the axial direction of the coil spring 20; the two ends of the coil spring 20 have positioning feet 201, and the positioning feet 201 are clamped in the positioning groove H1021 to make the coil spring 20 and the unlocking seat 10 relatively fixed in the circumferential direction. In this way, the positioning feet 201 on the coil spring 20 and the positioning groove H1021 on the unlocking seat 10 cooperate to conveniently realize the circumferential fixation of the coil spring 20 and the unlocking seat 10.

[0090] The present invention provides a lock having the unlocking drive mechanism as described above, and the lock can be but is not limited to a door lock.

[0091] The lock according to the present invention has the unlocking drive mechanism, which can improve the reliability of the lock.

[0092] Reference Figures 8 to 11As shown, the present invention provides a handle lock, comprising a clutch seat 50, a handle 60, an elastic lock pin 70 and the unlocking drive mechanism as described in the above embodiment.

[0093] Specifically, the clutch seat 50 has an axial locking hole H501 and a radial pin hole communicating with the axial shaft hole.

[0094] The handle 60 includes a pivot portion 601 and a handle portion 602. The pivot portion 601 is sleeved on the outside of the clutch seat 50 and can pivot relative to the clutch seat 50. The inner wall of the pivot portion 601 is provided with an axially extending slot 6011. The handle portion 602 is connected to the pivot portion 601 for user operation.

[0095] The elastic locking pin 70 is arranged in the radial pin hole, and one end of the elastic locking pin 70 is abutted in the slot 6011. By abutting the elastic locking pin 70 in the slot 6011 of the pivot part 601, the pivot part 601 and the clutch seat 50 can be relatively fixed in the circumferential direction, that is, the handle 60 and the clutch seat 50 can be relatively fixed in the circumferential direction.

[0096] The unlocking drive mechanism is disposed in the handle 60 , and when the pivot shaft 30 pivots, the unlocking seat 10 is pushed into or out of the axial locking hole H501 through the coil spring 20 .

[0097] When the unlocking seat 10 enters the axial locking hole H501, the other end of the elastic locking pin 70 is stopped by the unlocking seat 10, and the handle 60 and the clutch seat 50 are relatively locked; when the unlocking seat 10 exits the axial locking hole H501, the unlocking seat 10 releases the elastic locking pin 70, so that the handle 60 and the clutch seat 50 can pivot relative to each other.

[0098] In a specific application, the clutch seat 50 can be connected to the lock core 80. When the door needs to be opened, the unlocking seat 10 can be driven by the driving device 40 connected to the pivot shaft 30 to insert into the axial lock hole H501. At this time, since the elastic lock pin 70 is blocked by the unlocking seat 10, the elastic lock pin 70 cannot move into the axial lock hole H501, so that the upper end of the elastic lock pin 70 remains abutted against the slot 6011 of the pivot part 601, and the pivot part 601 and the clutch seat 50 remain relatively fixed in the circumferential direction. The user only needs to turn the handle 60, and the clutch seat 50 will rotate with the handle 60 to drive the lock core 80 to unlock and open the door. When the door needs to be locked, the unlocking seat 10 can be driven to withdraw from the axial lock hole H501 by the driving device 40 connected to the pivot shaft 30. At this time, since the elastic lock pin 70 is no longer blocked by the unlocking seat 10, the elastic lock pin 70 can move into the axial lock hole H501. When the user turns the handle 60, the elastic lock pin 70 in the slot 6011 retracts into the axial lock hole H501, the pivot part 601 rotates, and the clutch seat 50 does not move. In this way, the door cannot be unlocked and remains locked and closed.

[0099] According to the handle lock of the present invention, there is the above-mentioned unlocking drive mechanism. When the lock is struck or violently vibrated, the rotation of the push pin 301 needs to overcome the greater resistance from the spring coil. Therefore, the pivot shaft 30 and the push pin 301 thereon are not easy to rotate, and the unlocking seat 10 is not easy to disengage from the axial lock hole H501, thereby keeping the lock in a locked state, thereby improving the reliability of the handle lock.
