DETAILED DESCRIPTION

[0049] To make the objects, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the drawings in the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0050] The following will be combined with Figures 1 to 12 to describe the lock clutch device 100 provided in the embodiments of the present application.

[0051] Specifically, the lock clutch device 100 comprises a shell 1, a first transmission member 4, and a dial piece 2.

[0052] The shell 1 is provided with a first through hole 101 and a second through hole 102 through which the limiting member 7 can pass, that is, the limiting member 7 can selectively pass through the first through hole 101 or the second through hole 102. Optionally, the limiting member 7 is provided as a threaded member or a pin shaft.

[0053] The first transmission member 4 is rotationally connected with the shell 1. One end of the first transmission member 4 extends out of the shell 1 and is used for connecting the handle 8. Optionally, the end of the first transmission member 4 extending out of the shell 1 is provided as a square structure, and the handle 8 is sleeved outside the first transmission member 4.

[0054] The dial piece 2 is connected with the part of the first transmission member 4 inside the shell 1, and the dial piece 2 is provided with a limiting part 201. The rotation path of the limiting part 201 passes through the first through hole 101 and the second through hole 102, that is, the first through hole 101 and the second through hole 102 are distributed on the rotation path of the limiting part 201. Optionally, as shown in Figure 11 , the dial piece 2 is sleeved outside the first transmission member 4 and is keyed connected with the first transmission member 4.

[0055] In the state that the dial piece 2 is turned to the first position and the limiting piece 7 passes through the first through hole 101, the limiting piece 7 is arranged on the first side of the limiting part 201 to limit the rotation of the limiting part 201 to the first direction.

[0056] In the state that the dial piece 2 is turned to the second position and the limiting piece 7 passes through the second through hole 102, the limiting piece 7 is arranged on the second side of the limiting part 201 to limit the rotation of the limiting part 201 to the second direction.

[0057] In the embodiment, as shown in the figure, for the convenience of description, it is assumed that the first direction is the counterclockwise direction in the figure and the second direction is the clockwise direction in the figure, and it can be understood that the assumption is only for the convenience of description of the scheme and should not be understood as a limitation on the protection scope of the scheme. Figures 6-11 As shown in the figure, the dial piece 2 is in the first position and the limiting piece 7 passes through the first through hole 101, and the limiting piece 7 limits the rotation of the limiting part 201 to the first direction, so that the dial piece 2 can only rotate to the second direction in this state. Assuming that the handle 8 is arranged towards the right side in the figure at this time, the handle 8 can only rotate in the second direction and cannot rotate in the first direction in this state, that is, the handle 8 can only be pressed down and cannot be lifted up, so that the handle 8 can be applied to the occasion of opening the door body on the right side.

[0058] Figure 8 As shown in the figure, the dial piece 2 is in the second position and the limiting piece 7 passes through the second through hole 102, and the limiting piece 7 limits the rotation of the limiting part 201 to the second direction, so that the dial piece 2 can only rotate to the first direction in this state. Assuming that the handle 8 is arranged towards the left side in the figure at this time, the handle 8 can only rotate in the first direction and cannot rotate in the second direction in this state, that is, the handle 8 can only be pressed down and cannot be lifted up, so that the handle 8 can be applied to the occasion of opening the door body on the left side.

[0059] Figure 6 Figure 7 The lock clutch device 100 provided in the embodiment of the utility model can make the limiting piece 7 and the limiting part 201 on the dial piece 2 have corresponding limiting position relationships only by adjusting the dial piece 2 to the first position or the second position and then passing the limiting piece 7 through the first through hole 101 or the second through hole 102 when the direction of the handle 8 needs to be adjusted, and the installation position of the limiting piece 7 is convenient to touch, so that the limiting piece 7 is more convenient to install without passing the limiting piece 7 into the shell 1 and then being connected with the threaded hole on the dial piece 2.

[0060] The lock clutch device 100 provided in the embodiment of the utility model can make the limiting piece 7 and the limiting part 201 on the dial piece 2 have corresponding limiting position relationships only by adjusting the dial piece 2 to the first position or the second position and then passing the limiting piece 7 through the first through hole 101 or the second through hole 102 when the direction of the handle 8 needs to be adjusted, and the installation position of the limiting piece 7 is convenient to touch, so that the limiting piece 7 is more convenient to install without passing the limiting piece 7 into the shell 1 and then being connected with the threaded hole on the dial piece 2.

[0061] Figure 11 ​​​​As shown, in some embodiments provided by the utility model, the limiting part 201 includes the first limiting protrusion 2011 and the second limiting protrusion 2012, and the rotating paths of the first limiting protrusion 2011 and the second limiting protrusion 2012 both pass through the first through hole 101 and the second through hole 102. For example, the first limiting protrusion 2011 and the second limiting protrusion 2012 are distributed along the circumferential direction of the rotating axis of the first transmission member 4.

[0062] Wherein, in the state that the dial 2 rotates to the first position and the limiting piece 7 passes through the first through hole 101, the limiting piece 7 is arranged on the side of the first limiting protrusion 2011 away from the second limiting protrusion 2012.

[0063] In the state that the dial 2 rotates to the second position and the limiting piece 7 passes through the second through hole 102, the limiting piece 7 is arranged on the side of the second limiting protrusion 2012 away from the first limiting protrusion 2011.

[0064] Since the handle 8 needs to be rotated by 180 degrees when changing direction, the dial 2 needs to be rotated by 180 degrees, and in the embodiment, the first limiting protrusion 2011 and the second limiting protrusion 2012 are respectively responsible for contacting the limiting part 201 when the dial 2 rotates to a specific position, and since there is a spacing between the first limiting protrusion 2011 and the second limiting protrusion 2012, the included angle between the line connecting the first through hole 101 and the first transmission member 4 and the line connecting the second through hole 102 and the first transmission member 4 can be less than 180 degrees, so that the positions of the first through hole 101 and the second through hole 102 are closer, so as to improve the compactness of the lock clutch device 100.

[0065] Optionally, referring to Figure 11 As shown, the first limiting protrusion 2011 and the second limiting protrusion 2012 are both provided in a flange structure. The flange structure can provide a more flat and stable contact surface, so that the contact between the limiting protrusion and the limiting piece 7 is more reliable. The flange structure can be formed by one-time molding through processes such as stamping and bending, without the need for additional welding or assembly steps, thereby simplifying the manufacturing process and reducing production costs. The flange structure is directly formed from the base material without the need for additional materials, thereby reducing material waste.

[0066] In some embodiments provided by the utility model, the dial 2 is further provided with a clamping part 202, and the lock clutch device 100 further includes an elastic assembly 3, and the elastic assembly 3 is connected with the shell 1.

[0067] Wherein, in the state that the dial 2 rotates to the first position, the elastic assembly 3 abuts against the first side of the clamping part 202 and is used to drive the clamping part 202 to rotate in the first direction.

[0068] In the state that the dial 2 rotates to the second position, the elastic assembly 3 abuts against the second side of the clamping part 202 and drives the clamping part 202 to rotate in the second direction.

[0069] In the embodiment, as shown in FIG. 1, the dial 2 is in the first position, and the limiting part 201 is limited by the limiting member 7 to rotate in the first direction, so that the dial 2 can only rotate in the second direction at this time. The elastic assembly 3 is used to drive the dial 2 to rotate in the first direction, so that the limiting part 201 of the dial 2 abuts against the limiting member 7. Figure 8 For example, the handle 8 is arranged towards the right side in the figure, so that the handle 8 can only rotate in the second direction at this time and cannot rotate in the first direction. Further, if the user presses the handle 8 to make the dial 2 rotate in the second direction, the clamping part 202 compresses the elastic assembly 3. After the user releases the handle 8, the elastic assembly 3 drives the dial 2 to rotate in the first direction through the limiting part 201 until the limiting part 201 abuts against the limiting member 7, so as to reset the handle 8.

[0070] As shown in FIG. 2, the dial 2 is in the second position, and the limiting member 7 passes through the second through hole 102, and the limiting member 7 limits the limiting part 201 to rotate in the second direction, so that the dial 2 can only rotate in the first direction at this time. The elastic assembly 3 is used to drive the dial 2 to rotate in the second direction, so that the limiting part 201 of the dial 2 abuts against the limiting member 7.

[0071] Figure 6 For example, the handle 8 is arranged towards the left side in the figure, so that the handle 8 can only rotate in the first direction at this time and cannot rotate in the second direction. Further, if the user presses the handle 8 to make the dial 2 rotate in the first direction, the clamping part 202 compresses the elastic assembly 3. After the user releases the handle 8, the elastic assembly 3 drives the dial 2 to rotate in the second direction through the limiting part 201 until the limiting part 201 abuts against the limiting member 7, so as to reset the handle 8. Figure 7 In this way, by arranging the elastic assembly 3, the handle 8 and the dial 2 can be driven to reset after the user operates the handle 8, so that the handle 8 can always be kept in the unlocked position, eliminating the need for the user to manually push the handle 8 back to the original position, simplifying the operation process and improving the use convenience.

[0072] In this way, by arranging the elastic assembly 3, the handle 8 and the dial 2 can be driven to reset after the user operates the handle 8, so that the handle 8 can always be kept in the unlocked position, eliminating the need for the user to manually push the handle 8 back to the original position, simplifying the operation process and improving the use convenience.

[0073]

[0074] ​​Optionally, the driving part is provided in a flange structure. The flange structure can provide a more flat and stable contact surface, so that the contact between the driving part and the elastic assembly 3 is more reliable. The flange structure can be formed by one-time molding through processes such as stamping and bending, without the need for additional welding or assembly steps, simplifying the manufacturing process and reducing production costs. The flange structure is directly formed from the base material without the need for additional materials, reducing material waste.

[0075] Referring to Figure 7 and Figure 8 , in some embodiments of the present application, the elastic assembly 3 includes a torsion spring. The torsion spring includes a first torsion arm 301 and a second torsion arm 302.

[0076] The housing 1 is provided with a first cooperating part 103 and a second cooperating part 104. The first cooperating part 103 is arranged on one side of the first torsion arm 301 and limits the rotation of the first torsion arm 301 in the first direction. The second cooperating part 104 is arranged on one side of the second torsion arm 302 and limits the rotation of the second torsion arm 302 in the second direction.

[0077] In the state that the knob 2 is rotated to the first position, the clamping part 202 is arranged on one side of the first torsion arm 301 close to the first cooperating part 103. In the state that the knob 2 is rotated to the second position, the clamping part 202 is arranged on one side of the second torsion arm 302 close to the second cooperating part 104.

[0078] In this embodiment, referring to Figure 8 , in the state that the knob 2 is rotated to the first position, the clamping part 202 is arranged on one side of the first torsion arm 301 close to the first cooperating part 103. In the process of rotating the knob 2 in the second direction, the clamping part 202 drives the first torsion arm 301 to rotate in the second direction, and the second cooperating part 104 limits the rotation of the second torsion arm 302 in the second direction, so that the clamping part 202 and the second cooperating part 104 jointly compress the torsion spring.

[0079] Referring to Figure 7 , in the state that the knob 2 is rotated to the second position, the clamping part 202 is arranged on one side of the second torsion arm 302 close to the second cooperating part 104. In the process of rotating the knob 2 in the first direction, the clamping part 202 drives the second torsion arm 302 to rotate in the first direction, and the first cooperating part 103 limits the rotation of the first torsion arm 301 in the first direction, so that the clamping part 202 and the first cooperating part 103 jointly compress the torsion spring.

[0080] In this way, the handle 8 and the knob 2 can be driven to reset by the elastic assembly 3 regardless of whether they are in the first position or the second position, without the need to rotate the position of the elastic assembly 3 to adapt to the position of the knob 2, so that there is no need to worry about whether the position of the elastic assembly 3 is correct, thereby making the reversing operation of the handle 8 simpler.

[0081] Of course, the elastic assembly 3 is not limited to the above form, for example, the elastic assembly 3 can include two elastic members, one of which is used to abut against the clamping portion 202 when the dial 2 is at the first position, and the other is used to abut against the clamping portion 202 when the dial 2 is at the second position. Further, the elastic member can be a spring or a torsion spring.

[0082] In some embodiments provided by the utility model, the lock clutch device 100 further comprises a second transmission member 5 and a clutch mechanism 6.

[0083] The second transmission member 5 is rotatably connected with the shell 1, one end of the second transmission member 5 extends out of the shell 1 and is used for connecting the lock cylinder.

[0084] The clutch mechanism 6 is connected with the second transmission member 5 and is used for engaging or disengaging with the dial 2.

[0085] In the embodiment, when the lock clutch device 100 is applied to a lock, the first transmission member 4 is connected with the handle 8, the second transmission member 5 is connected with the lock cylinder of the lock, when no password is input to the lock or the password is incorrect, the clutch mechanism 6 does not act, and the second transmission member 5 and the dial 2 cannot transmit power, so that only the dial 2 can be rotated by rotating the handle 8, and the dial 2 cannot be unlocked.

[0086] When a correct password is input to the lock, the clutch mechanism 6 acts, the second transmission member 5 and the dial 2 are engaged, and then the handle 8 is rotated, the handle 8 drives the dial 2 to rotate, the dial 2 drives the second transmission member 5 to rotate through the clutch mechanism 6, and the second transmission member 5 drives the lock cylinder of the lock to unlock.

[0087] Reference Figure 12 As shown in some embodiments provided by the utility model, the clutch mechanism 6 comprises a pin shaft 601, a driving device 602 and a reset member 603.

[0088] The pin shaft 601 is slidably arranged on the second transmission member 5 in the direction of approaching or moving away from the dial 2, and the dial 2 is provided with a clamping groove for inserting the pin shaft 601.

[0089] The driving device 602 is installed in the shell 1 and is used for driving the pin shaft 601 to move in the direction of approaching the dial 2.

[0090] The reset member 603 is arranged between the pin shaft 601 and the second transmission member 5 and is used for driving the pin shaft 601 to slide in the direction of moving away from the dial 2.

[0091] In the embodiment, when no password is input to the lock or the password is incorrect, the driving device 602 does not act, so that the pin shaft 601 cannot be inserted into the clamping groove of the dial 2. The second transmission member 5 and the dial 2 cannot transmit power, so that only the dial 2 can be rotated by rotating the handle 8, and the dial 2 cannot be unlocked.

[0092] When the correct password is input to the lock, the driving device 602 drives the pin shaft 601 to slide, the pin shaft 601 compresses the reset member 603 and is inserted into the clamping groove of the dial 2, so that the second transmission member 5 is engaged with the dial 2. The knob 8 is rotated, the knob 8 drives the dial 2 to rotate, the dial 2 drives the second transmission member 5 to rotate through the pin shaft 601, and the second transmission member 5 drives the lock core of the lock to be unlocked.

[0093] Optionally, the driving device 602 is a push plate motor. The reset member 603 is a spring.

[0096] The lock clutch device 100 is arranged in the inside of the lock shell 14, and the first transmission member 4 passes through the lock shell 14 and is connected with the knob 8.

[0097] The lock comprises the lock clutch device 100, and all advantages of the lock clutch device 100 are also included, so the advantages will not be repeated.

[0098] Optionally, the lock comprises but is not limited to a smart lock or an electronic lock.

[0099] In some embodiments of the utility model, the first mounting hole is arranged at the position opposite to the first through hole 101 on the lock shell 14, and the second mounting hole is arranged at the position opposite to the second through hole 102.

[0100] Optionally, the first mounting hole and the second mounting hole are both threaded holes, the limiting member 7 is a threaded member, the first through hole 101 and the second through hole 102 are both relief holes, and the threaded member is selectively screwed with the first mounting hole or the second mounting hole and passes through the first through hole 101 and the second through hole 102.

[0101] Optionally, the first mounting hole and the second mounting hole are both relief holes, and the first through hole 101 and the second through hole 102 are both threaded holes.

[0102] In some embodiments of the utility model, reference is made to Figure 2As shown, the side of the lock shell 14 away from the handle 8 is provided with a connecting column 13, which is used to pass through the door body and be connected with the rear lock body of the lock. The number of the connecting column 13 is at least two, and the at least two connecting columns 13 are distributed along the circumferential direction of the rotation axis of the first transmission member 4.
