The unlocking drive mechanism, the lock, and the handle lock according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 5, an unlocking driving mechanism provided according to an embodiment of the present invention may be applied to, but is not limited to, a lock, and includes an unlocking seat 10, a coil spring 20, and a pivot shaft 30.

Specifically, the unlocking seat 10 may be used to unlock or lock a locked member in a lock, and the locked member may be a lock pin or the like in the lock. The unlocking seat 10 is provided with a stopper 101.

A coil spring 20 is fixed to the unlocking seat 10, an end of the coil spring 20 abuts against the stopper 101, and the stopper 101 is configured to apply an unbalanced force to a circumferential direction of the end of the coil spring 20 to tilt the coils of the coil spring 20.

That is, on the one hand, the coil spring 20 is fixed relative to the unlocking seat 10, and when an external force is applied, 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 by the coil spring 20 to move in the axial direction. On the other hand, the coil spring 20 is not in a natural state but in an unbalanced compression state on the unlocking seat 10, 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, and the coil spring 20 is compressed by different amounts at different positions in the circumferential direction due to the unbalanced force applied to the end of the coil spring 20, so that the coils of the coil spring 20 are inclined to one side.

The pivot shaft 30 is pivotable around its axis and is inserted into the coil spring 20, and a pushing pin 301 extending in the radial direction is provided on the pivot shaft 30, and the pushing pin 301 is located between two adjacent coils on the coil spring 20.

That is, the pivot shaft 30 is rotatable in the coil spring 20 relative to the coil spring 20, and since the pushing 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 pushing pin 301 applies pressure to the coils, so that the coil spring 20 pushes the unlocking seat 10 to move, and the unlocking or locking of the locked member is realized by the unlocking seat 10. For example, in a lock application, the unlocking seat 10 moves between an unlocking position where the unlocking seat 10 is away from the locked member to unlock the locked member and a locking position where the unlocking member is close to the locked member to restrict the movement of the locked member to lock the locked member.

In the present application, since the coils of the coil spring 20 are inclined by the unbalanced pressure applied by the stopper 101, when the pushing pin 301 on the pivot shaft 30 is engaged with the inclined coils, the resistance to be overcome when the pushing pin 301 rotates is increased, that is, the coils are forced to incline by the unbalanced force applied, thereby increasing the resistance to be overcome when the pushing pin 301 rotates.

It should be noted that, in various application scenarios of the spring, the spring is usually compressed in a balanced manner, for example, both ends of the spring are abutted against a plane perpendicular to an axis of the spring, so that both ends of the spring can receive a balanced acting force, and the spring is compressed in a balanced manner (the coils are not forced to tilt), so as to ensure reliable performance of the spring. Also, in the related art lock, in the unlocking mechanism using a spring engaged with the push pin 301 on the pivot shaft 30, both ends of the spring are also abutted against the flat surface (as shown in fig. 7), and the balanced compression state is maintained, so that the push pin needs to overcome the resistance force (F resistance 2) when rotating. In the present application, the traditional spring application mode is broken through, and the coils of the coil spring 20 are forced to incline by the unbalanced acting force, so as to increase the resistance (F resistance 1, obviously, F resistance 1 is greater than F resistance 2) to be overcome when the pushing pin 301 rotates, and the resistance can prevent the unlocking seat 10 from moving due to vibration.

According to the unlocking driving mechanism of the present invention, when the push pin 301 on the pivot shaft 30 rotates with the pivot shaft 30, the spiral spring 20 can be pushed, and then the spiral spring 20 pushes the unlocking seat 10 to move, so as to realize unlocking or locking, and since the stopper portion 101 of the unlocking seat 10 is configured to apply an unbalanced force to the circumferential direction of the end portion of the coil spring 20, so as to incline the coils of the coil spring 20, when the inclined loops are engaged with the pushing pin 301, therefore, the pushing pin 301 needs to rotate against the greater resistance from the coil, and, as such, when the lock is knocked or violently shaken, since the pushing pin 301 needs to overcome the greater resistance from the coil to rotate, therefore, the pivot shaft 30 and the pushing pin 301 thereon are not easy to rotate, the unlocking seat 10 is not easy to move, and the lock is kept in a locking state, so that the reliability of the lock is improved.

Referring to fig. 1 to 5, 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 and is configured to drive the pivot shaft 30 and the pushing pin 301 to rotate, so that the pushing pin 301 pushes the unlocking seat 10 to move through the coil spring 20. That is, the pivot shaft 30 can be driven to rotate by the driving device 40, and the coil spring 20 and the unlocking seat 10 are pushed to move by the rotation of the pivot shaft 30 and the pushing pin 301, so that the driving of the pivot shaft 30 is facilitated.

Alternatively, the driving device 40 is a knob or a motor, the knob may be manually operated by a user, and when unlocking or locking is required, the user may operate the knob, for example, an anti-locking knob on a door lock. The motor can realize automatic control operation, for example, the unlocking or locking of the motor can be controlled by using biological characteristics such as passwords or fingerprints.

Referring to fig. 4, in one embodiment of the invention, the stop 101 abuts against a partial position of the end of said helical spring 20. For example, the stopper 101 only applies a force to a local position (for example, an upper part in the circumferential direction) of the end of the coil spring 20, and the coil is forced to incline to one side (right side) by the local position of the coil spring 20 receiving a force due to a large compression amount. For example, the stopper applies different forces to two different local positions of the end of the coil spring 20, and the coil is inclined to one side due to different compression amounts of the coil spring 20 at the different positions due to different forces applied to the two local positions.

That is, in the present embodiment, the stopping portion 101 applies pressure to a local position of the coil spring 20, so that the end portion of the coil spring 20 is forced to incline to one side due to uneven force, the structure is simple, and the coil inclination of the coil spring 20 is conveniently realized.

It will be appreciated that the stop 101 may be formed as a relatively small sized boss structure (as shown in fig. 4) to facilitate interference with the local position of the end of the coil spring 20, thereby generating a local force for forcing the coil of the coil spring 20 to tilt.

Referring to fig. 3 and 5, in another embodiment of the present invention, the stopper 101 has a slope S10, and the slope S10 abuts against the end of the coil spring 20.

That is, in the present embodiment, the stopper 101 is configured in a wedge shape, the end of the coil spring 20 directly abuts against the inclined surface S10 of the stopper 101, and it can be understood that the end of the coil spring 20 may be in a partial position abutting against the inclined surface S10 of the stopper 101, or the end of the coil spring 20 completely abuts against the inclined surface S10 of the stopper 101, so that the end of the coil spring 20 is compressed unevenly by the inclined surface S10, and the coils of the coil spring 20 are forced to incline, which is simple in structure and can keep the coil spring 20 stably installed.

It should be noted that, there may be one stopping portion 101 (as shown in fig. 3 and 4) or two stopping portions 101 (as shown in fig. 5), when there is one stopping portion 101, one end portion of the coil spring 20 abuts against the stopping portion 101, and the other end portion of the coil spring 20 may abut against the unlocking seat 10, or may be fixed to the unlocking seat 10 by another structural member, and one stopping portion 101 may apply an unbalanced force to one end portion of the coil spring 20, so that one end of the coil spring 20 may be tilted.

When there are two stopping portions 101, one end of the coil spring 20 abuts against one of the two stopping portions 101, the other end of the coil spring 20 abuts against the other of the two stopping portions 101, and the coil inclination directions of the coil spring 20 are the same when the two ends of the coil spring 20 are respectively subjected to the acting forces exerted by the two stopping portions 101. In the example of fig. 5, one of the stoppers 101 abuts against an upper portion of one end of the coil spring 20, and the other stopper 101 abuts against a lower portion of the other end of the coil spring 20, thus ensuring that the coil inclination directions of the coil spring 20 are the same.

That is, by applying unbalanced forces to both end portions of the coil spring 20 by the two stoppers 101, respectively, both end portions of the coil spring 20 can be inclined, and the inclination directions of both end portions of the coil spring 20 are the same, so that it is possible to ensure that the coil inclination angle of the coil spring 20 is larger, and correspondingly, the resistance to the pushing pin 301 is larger.

Referring to fig. 1 to 5, in an embodiment of the invention, an accommodating groove H10 is provided on the unlocking seat 10, the accommodating groove H10 has two opposite end walls H101, the stopping portion 101 is provided on the end wall H101 and protrudes into the accommodating groove H10, the coil spring 20 is accommodated in the accommodating groove H10, and an end portion of the coil spring 20 abuts against the stopping portion 101.

In this embodiment, the accommodating groove H10 is disposed on the unlocking seat 10, and the coil spring 20 is disposed in the accommodating groove H10, so that the installation of the coil spring 20 is facilitated, and the two end portions of the coil spring 20 respectively abut against the stop portions on the two end walls H101 or the end wall H101 of the accommodating groove H10, so that the coil spring 20 can be reliably installed and forms an inclined state.

Optionally, through holes are respectively formed in the two end walls H101 of the accommodating groove H10, and the pivot shaft 30 penetrates through the through hole in one end wall H101, and penetrates through the coil spring 20 and then penetrates through the through hole in the other end wall H101, so that the installation of the pivot shaft 30 is facilitated, and meanwhile, the unlocking seat 10 is also facilitated to move along the axial direction of the pivot shaft 30.

Illustratively, the accommodating groove H10 further has a side wall H102, 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 end parts of the coil spring 20 are provided with positioning pins 201, and the positioning pins 201 are clamped in the positioning grooves H1021, so that the coil spring 20 and the unlocking seat 10 are circumferentially and relatively fixed, and thus, the circumferential fixation of the coil spring 20 and the unlocking seat 10 is conveniently realized by utilizing the matching of the positioning pins 201 on the coil spring 20 and the positioning grooves H1021 on the unlocking seat 10.

The invention provides a lock which is provided with the unlocking driving mechanism, and the lock can be but is not limited to a door lock.

According to the lockset provided by the invention, the reliability of the lockset can be improved by the unlocking driving mechanism.

Referring to fig. 8 to 11, the present invention provides a handle lock, which comprises a clutch base 50, a handle 60, a resilient latch 70 and an unlocking driving mechanism as described in the above embodiments.

Specifically, the clutch seat 50 has an axial lock hole H501 and a radial pin hole communicating with the axial shaft hole.

The handle 60 comprises a pivot part 601 and a handle part 602, the pivot part 601 is sleeved outside the clutch seat 50 and can pivot relative to the clutch seat 50, an axially extending clamping groove 6011 is arranged on the inner wall of the pivot part 601, and the handle part 602 is connected with the pivot part 601 for a user to operate.

The elastic lock pin 70 is arranged in the radial pin hole, one end of the elastic lock pin 70 abuts against the clamping groove 6011, and the elastic lock pin 70 abuts against the clamping groove 6011 of the pivot part 601, so that the pivot part 601 and the clutch seat 50 are circumferentially fixed relatively, that is, the handle 60 and the clutch seat 50 are circumferentially fixed relatively.

The unlocking driving mechanism is arranged in the handle 60, and when the pivot shaft 30 pivots, the helical spring 20 pushes the unlocking seat 10 to enter or exit the axial lock hole H501.

When the unlocking seat 10 enters the axial locking hole H501, the other end of the elastic lock pin 70 is stopped by the unlocking seat 10, so that the handle 60 and the clutch seat 50 are locked relatively; 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 relatively.

In a specific application, the clutch seat 50 may be connected to the lock cylinder 80, when the door needs to be opened, the driving device 40 connected to the pivot shaft 30 may drive the unlocking seat 10 to be inserted into the axial lock hole H501, at this time, because the elastic lock pin 70 is blocked by the unlocking seat 10, the elastic lock pin 70 may not move towards the axial lock hole H501, so that the upper end of the elastic lock pin 70 is kept in the clamping groove 6011 of the pivot portion 601, the pivot portion 601 and the clutch seat 50 are circumferentially fixed relatively, and the user only needs to rotate the handle 60, and the clutch seat 50 rotates along with the handle 60 to drive the lock cylinder 80, so as to unlock the door. When the door needs to be locked, the driving device 40 connected to the pivot shaft 30 can drive the unlocking seat 10 to exit from the axial locking hole H501, 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 locking hole H501, when the user rotates the handle 60, the elastic lock pin 70 in the clamping groove 6011 retracts into the axial locking hole H501, the pivot part 601 rotates, and the clutch seat 50 does not move, so that the door cannot be unlocked and kept locked.

According to the handle lock provided by the invention, when the lock is knocked or violently shaken, the pushing pin 301 needs to overcome large resistance from the spring coil due to rotation, so that the pivot shaft 30 and the pushing pin 301 on the pivot shaft are not easy to rotate, the unlocking seat 10 is not easy to be disengaged from the axial lock hole H501, the lock is kept in a locked state, and the reliability of the handle lock is improved.
