[0002] The lock body is an essential safety protection device for every household and is often installed on doors and cabinet doors. Only users with the corresponding keys, biometric information or passwords have the corresponding authority to unlock the door or cabinet door.

[0003] In the related art, the knob is often linked with the transmission. When the lock body is in the unlocked state, the knob can drive the transmission to rotate to unlock the lock, while when the lock body is in the closed state, the transmission is fixed and cannot rotate; therefore, when an external force is used to rotate the knob, one end of the transmission is also twisted.

[0004] With respect to the above-mentioned related technologies, when the external force is large, one end of the transmission member is fixed and the other end is twisted, so the transmission member is easily deformed or even damaged. Summary of the invention

[0005] In order to protect the transmission parts from deformation and damage, the present application provides an idling clutch mechanism of an electronic lock and an electronic lock having the same.

[0006] In the first aspect, the present application provides an electronic lock idling clutch mechanism adopts the following technical solution:

[0011] By adopting the above technical solution, the linkage sleeve can rotate with the fixed seat, and the rotation of the driving motor can realize the linkage of the first clutch member with the linkage sleeve and the knob member, so that when the knob member rotates, the transmission member also rotates synchronously with the linkage sleeve to realize the unlocking function; the first clutch member can also be controlled by the driving motor to be located in the linkage sleeve, so that the linkage sleeve and the knob member are separated from each other. When the knob member is rotated, the transmission member will not be twisted, so the transmission member is not easily deformed or damaged.

[0012] Optionally, the knob member includes a knob portion and a clutch portion coaxially fixed to the knob portion; the linkage sleeve is sleeved outside the clutch portion, and the clutch portion is rotatably connected to the linkage sleeve;

[0013] The clutch portion is provided with a first clutch hole, and the linkage sleeve is provided with a first linkage hole. The first clutch hole and the first linkage hole are used for allowing the first clutch member to move to the linkage position.

[0014] By adopting the above technical solution, the knob part is convenient for the user to twist the knob part by hand; when the first clutch part is located in the first clutch hole and the first linkage hole, the clutch part and the linkage sleeve are linked to each other, so that when the knob part is twisted, the clutch part fixed to the knob part drives the linkage sleeve to rotate, so that the linkage sleeve drives the transmission part to rotate, thereby realizing the unlocking function.

[0015] Optionally, the first clutch component is a locking bolt, a sliding groove is provided in the clutch portion, the sliding groove is communicated with the first clutch hole, and the locking bolt is slidably matched with the sliding groove.

[0016] By adopting the above technical solution, the structure of the lock bolt is simple, and the clutch part and the linkage sleeve can be linked or separated from each other by controlling the sliding position, thereby realizing two state changes of the separation position and the linkage position.

[0017] Optionally, a return spring is arranged in the slide groove, one end of the return spring abuts against an end of the locking bolt away from the first clutch hole, and the other end of the return spring abuts against the side wall of the slide groove.

[0018] By adopting the above technical solution, the reset spring can generate a force to push the lock bolt toward the first clutch hole, and the motor can control the lock bolt to be retracted into the clutch part, so the setting of the reset spring can facilitate the movement of the lock bolt.

[0019] Optionally, a linkage groove is provided on a side of the lock bolt facing the motor, and an eccentric shaft is provided at the output end of the motor; the eccentric shaft is located in the linkage groove.

[0020] By adopting the above technical solution, since the output end of the motor is provided with an eccentric shaft, the position of the eccentric shaft changes with the rotation of the output end of the motor, and the movement position of the locking bolt can be controlled in cooperation with the reset spring.

[0021] Optionally, the fixing seat is further provided with a slideway and a second mounting groove; a mechanical lock core is rotatably connected in the second mounting groove, the slideway is connected to the first mounting groove and the second mounting groove, a clutch ejector pin and a second clutch member are slidably arranged in the slideway, and the second clutch member is farther away from the second mounting groove than the clutch ejector pin;

[0022] The linkage sleeve is provided with a second linkage hole, the clutch portion is provided with a second clutch hole, and the axis of the second linkage hole, the axis of the second clutch hole and the axis of the slideway are all located on the same plane;

[0023] An eccentric block is provided at one end of the mechanical lock core close to the slide. When the second linkage hole, the second clutch hole and the slide are connected, rotating the eccentric block can drive the clutch ejector pin to move to push the second clutch member to the second linkage hole and the second clutch hole, thereby realizing the linkage of the linkage sleeve and the knob member.

[0024] By adopting the above technical solution, when it is inconvenient to use a motor to control the first clutch component, a mechanical lock core can be used to realize the linkage between the clutch part and the linkage sleeve, thereby realizing the unlocking function and providing convenience for the user; the mechanical lock core is driven to rotate by a key, so that the eccentric block rotates to the side close to the slideway, thereby driving the clutch ejector pin to push the second clutch component into the second linkage hole and the second clutch hole, thereby realizing the linkage between the clutch part and the linkage sleeve.

[0025] Optionally, the second clutch member is a steel ball, and the clutch ejector pin is provided with a magnetic block that generates magnetic attraction with the steel ball.

[0026] By adopting the above technical solution, the magnetic block can attract the steel ball, so that when the second linkage hole, the second clutch hole and the slideway are coaxial, the steel ball is always in contact with the clutch ejector pin, and when the clutch ejector pin moves toward the second mounting groove, the second clutch member can be driven into the slideway to achieve separation between the clutch part and the linkage sleeve.

[0027] Optionally, a plurality of the second clutch holes and the second linkage holes are arranged at intervals.

[0028] By adopting the above technical solution, the provision of multiple second clutch holes and second linkage holes can make it easier for the steel balls to enter the second clutch holes and the second linkage holes, thereby reducing the rotation stroke of the knob and the linkage sleeve.

[0030] By adopting the above technical solution, the setting of the limit groove can limit the rotation of the clutch ejector, so that the clutch ejector is more stable in the process of sliding on the slide, and the contact area between the limit block and the eccentric block is larger. Therefore, during the rotation of the eccentric block, the limit block can maintain a state of contact with the eccentric block, so that the movement of the clutch ejector is more controllable; the reset spring exerts a force on the limit block toward the second mounting groove, so when the eccentric block rotates to the side away from the slide, the limit spring can drive the clutch ejector to move in the direction of the second mounting groove.

[0031] In the second aspect, the electronic lock provided by the present application adopts the following technical solution:

[0032] It includes the lock body idling clutch structure mentioned above.

[0033] By adopting the above technical solution, when the lock bolt is located in the clutch part and the steel ball is located in the slideway, the knob part and the linkage sleeve are in the separated position. At this time, the linkage sleeve and the clutch part rotate independently of each other, so the function of idling of the knob part can be realized; when the lock bolt is located in the first clutch hole and the first linkage hole, or the steel ball is located in the second clutch hole and the second linkage hole, the linkage sleeve and the clutch part are linked with each other, so when the knob part is rotated, the clutch part will drive the linkage sleeve to rotate, thereby driving the transmission part to rotate, thereby achieving the purpose of unlocking.

When the number of the second linkage hole 202 is greater than one, the axes between the second linkage holes 202 are all in the same plane. The rotation trajectory of the first linkage hole 201 and the rotation trajectory of the second linkage hole 202 do not overlap each other.

[0059] Reference Figure 4 , Figure 5 A mounting sleeve 21 is integrally provided at one end of the linkage sleeve 2. The mounting sleeve 21 is in the shape of a hollow cylinder, and the diameter of the mounting sleeve 21 is smaller than the diameter of the linkage sleeve 2. An annular groove 212 is provided on the outer peripheral side of the end of the mounting sleeve 21 away from the linkage sleeve 2. The annular groove 212 is provided along the outer peripheral surface of the mounting sleeve.

[0060] Reference Figure 1 , Figure 5The above-mentioned linkage sleeve 2 is placed in the first mounting groove 102, and the linkage sleeve 2 and the first mounting groove 102 are clearance-matched. With this arrangement, the connecting sleeve can rotate relative to the fixing seat 1. The mounting sleeve 21 passes through the clamping circular groove, and the annular clamping groove 212 is located outside the clamping circular groove. The mounting sleeve 21 is sleeved with a retaining spring 23 in the annular clamping groove 212. The retaining spring 23 is annular and has a notch. The retaining spring 23 is respectively provided with protruding pieces 231 at both ends of the notch, and the protruding pieces 231 are provided with fixing holes 2311. The retaining spring 23 can be made of elastic materials such as spring steel, and can be clamped into the annular clamping groove 212 through elastic deformation, so as to limit the axial movement of the mounting sleeve 21, thereby preventing the linkage sleeve 2 from being separated from the first mounting groove 102.

[0061] Reference Figure 4 , Figure 5 The annular groove 212 is spaced from the end of the mounting sleeve 21, and plug holes 214 are provided on opposite sides of the annular groove 212 and the end of the mounting sleeve 21, and the axes of the two plug holes 214 coincide. The mounting sleeve 21 also has a plug port 213 in a direction perpendicular to the axes of the two plug ports 214, and the plug port 213 extends from the end of the mounting sleeve 21 to the axial direction of the mounting sleeve 21.

[0062] Reference Figure 1 , Figure 5 The transmission member 22 is in a strip shape, and one end of the transmission member 22 is integrally connected with a clamping piece 221, and a mounting hole 2211 is provided in the clamping piece 221. The clamping piece 221 of the transmission member 22 is plugged and matched with the two plug interfaces 213, and the mounting hole 2211 is coaxially arranged with the plug hole 214, and a locking pin 222 is provided between the mounting hole 2211 and the plug hole 214 to achieve the fixing of the transmission member 22 and the linkage sleeve 2. Therefore, when the linkage sleeve 2 drives the mounting sleeve 21 to rotate, the transmission member 22 also rotates synchronously with the linkage sleeve.

[0063] Reference Figure 5 The aforementioned knob member 3 includes a knob portion 31 and a clutch portion 32, and both the knob portion 31 and the clutch portion 32 are cylindrical in shape with a hollow interior. A receiving opening is provided at one end of the knob portion 31, and the receiving opening is communicated with the interior of the knob portion 31. The clutch portion 32 is coaxially arranged at the other end of the knob portion 31, and a first clutch hole 322 is provided in the circumference of the clutch portion 32. A second clutch hole 323 is also provided in the circumference of the clutch portion 32. The number of second clutch holes 323 may be one, two or more. When the number of second clutch holes 323 is greater than one, the axes between the second clutch holes 323 are all in the same plane.

[0064] Reference Figure 5, the clutch part 32 is placed in the linkage sleeve 2, and the clutch part 32 and the linkage sleeve 2 are in clearance fit, so that the clutch part 32 and the linkage sleeve 2 can rotate relative to each other. At this time, the axis of the first clutch hole 322 and the axis of the first linkage hole 201 are in the same plane, and the axis of the second clutch hole 323 and the axis of the second linkage hole 202 are in the same plane. Therefore, during the relative rotation of the clutch part 32 and the linkage sleeve 2, the first clutch hole 322 and the first linkage hole 201 can rotate to a coaxial position, and the second clutch hole 323 and the second linkage hole 202 can rotate to a coaxial position.

A threaded hole 331 is formed at one end of the connecting tube 33 away from the clutch part 32 .

[0066] Reference Figure 5 The mounting sleeve 21 is provided with a matching circular hole at one end close to the linkage sleeve 2, and the matching circular hole connects the interior of the linkage sleeve 2 and the interior of the mounting sleeve 21. The diameter of the matching circular hole is smaller than the inner diameter of the mounting sleeve, so the matching circular hole at one end inside the mounting sleeve forms a limiting boss 211 with the inner wall of the mounting sleeve.

[0067] Reference Figure 5 When the clutch part 32 is placed in the linkage sleeve 2, the connecting tube 33 is also located in the matching circular hole. The threaded hole 331 is threaded with a screw 34, and the nail head of the screw 34 is located at the end of the connecting tube 33 away from the knob part 31, and abuts against the limiting boss 211. This arrangement plays a role in limiting the axial movement between the connecting tube 33 and the matching circular hole, thereby preventing the clutch part 32 from being separated from the linkage sleeve 2.

[0068] Reference Figure 1 , Figure 5 The outer periphery of the knob portion 31 is provided with straight knurling. When the user turns the knob 3, the hand contacts the straight knurling, which increases the friction between the hand and the knob 3 and has an anti-slip effect. In another embodiment, the straight knurling can also be a diagonal knurling, a mesh knurling or other three-dimensional textures with an anti-slip effect.

[0072] Reference Figure 5 , Figure 6 When the eccentric shaft 421 at the output end of the motor 42 rotates to a position close to the blind end of the slide slot 321, the distance between the end of the lock bolt 41 with the limiting hole 412 and the blind end is the smallest, and at this time, the stretched length of the reset spring 414 is less than the natural length, and the reset spring 414 is in a compressed state; the end of the lock bolt 41 away from the limiting hole 412 is located in the first clutch hole 322, and is flush with the outer peripheral side of the clutch part 32 or recessed in the outer peripheral side of the clutch part 32. At this time, the lock bolt 41 is in the separation position, and the linkage sleeve 2 and the knob member 3 can rotate relative to each other.

[0073] Reference Figure 5 , Figure 6When the eccentric shaft 421 at the output end of the motor 42 rotates to a position away from the blind end of the slide slot 321, the distance between the end of the lock bolt 41 with the limiting hole 412 and the blind end is the largest, and at this time, the stretching length of the reset spring 414 is greater than the stretching length of the reset spring 414 in the separation position; the end of the lock bolt 41 away from the limiting hole 412 passes through the first separation hole to reach the first linkage hole 201, and the end of the lock bolt 41 away from the limiting hole 412 is flush with the outer peripheral side of the linkage sleeve 2 or recessed in the outer peripheral side of the linkage sleeve 2. At this time, the lock bolt 41 is in the linkage position, and the linkage sleeve 2 and the knob 3 can achieve synchronous rotation.

Specifically, in one embodiment, a positioning ring is provided protrudingly on the outer periphery of the lock core sleeve 63, and correspondingly, an annular groove is provided on the inner side wall of the lock core sleeve 63, and the positioning ring cooperates with the annular groove. Therefore, when the mechanical lock core 6 rotates relative to the lock core sleeve 63, it is not easy for the mechanical lock core 6 and the lock core sleeve 63 to produce axial relative movement, so it is not easy for the mechanical lock core 6 and the lock core sleeve 63 to separate from each other. Use a key to insert the keyhole 62 and turn the key, and the mechanical lock core 6 can drive the eccentric block 61 to rotate. Since this part is a prior art, it will not be repeated in this embodiment. The eccentric block 61 can be a three-dimensional structure that deviates from the center of the circle. The shape of the eccentric block 61 can be square, circular, elliptical or other shapes. In the present embodiment, the eccentric block 61 is half a disc in shape.

[0079] Reference Figure 7 , Figure 8 The second clutch member can be a columnar latch or other components that can be placed in the second clutch hole 323 and the second linkage hole 202. In this embodiment, the second clutch member is a steel ball 51, and the diameter of the steel ball 51 is smaller than the slideway 101 and the second linkage hole 202. The magnetic block 522 has magnetic attraction to the steel ball 51, so the steel ball 51 can abut against the end of the clutch ejector pin 52 under the attraction of the magnetic block 522.

[0080] Reference Figure 7 , Figure 8When the eccentric block 61 rotates to the side of the second mounting groove 103 away from the slide 101, the limit spring 53 pushes the abutment plate 5211 to the position where the push plate 5212 abuts against the side surface where the diameter of the eccentric block 61 is located; at this time, the steel ball 51 is located in the slide 101, and the linkage sleeve 2 and the knob member 3 can rotate relative to each other.

[0081] Reference Figure 7 , Figure 8 When the eccentric block 61 rotates to the side of the second mounting groove 103 close to the slide 101, the limit spring 53 pushes the abutment plate 5211 to the position where the push plate 5212 abuts against the side of the arc edge of the eccentric block 61; at this time, the steel ball 51 is pushed from the slide 101 to the second linkage hole 202 until it reaches between the second linkage hole 202 and the second clutch hole 323, connecting the linkage sleeve 2 and the clutch part 32 together. When the user twists the knob part 31 of the knob member 3, the clutch part 32 connected to the knob part 31 also rotates accordingly, thereby realizing the linkage between the linkage sleeve 2 and the knob member 3.

[0082] Reference Figure 1 , Figure 8 Furthermore, the second clutch hole 323 and the second linkage hole 202 can be arranged in multiple intervals. Such an arrangement can make it easier for the steel ball 51 to engage with the second clutch hole 323 and the second linkage hole 202, making it easier to achieve linkage between the linkage sleeve 2 and the knob member 3.

[0083] The implementation principle of an idling clutch mechanism of an electronic lock in the embodiment of the present application is as follows: when the steel ball 51 is located in the slideway 101, the present application can control the sliding of the lock bolt 41 in the clutch part 32 by controlling the rotation of the motor 42. When the motor 42 rotates to the clutch position, the lock bolt 41 is completely located in the clutch part 32, so that when the knob part 3 is rotated, the linkage sleeve 2 does not rotate synchronously, and therefore the transmission member 22 does not rotate either, thereby realizing the idling function of the knob part 3; when the motor 42 rotates to the linkage position, the motor 42 drives the lock bolt 41 to slide from the slide groove 321 to the outside of the clutch part 32, and the lock bolt 41 is inserted into the first linkage hole 201, so that the linkage sleeve 2 and the knob part 3 are connected to each other. When the knob part 31 is rotated, the clutch part 32 integrally connected to the knob part 31 tube also rotates accordingly, thereby driving the clutch transmission member 22 to rotate, which helps to realize The function of unlocking; when the lock bolt 41 is located in the clutch part 32, the key is inserted into the keyhole 62, thereby driving the mechanical lock core 6 to twist, so that the eccentric block 61 can rotate with the rotation of the mechanical lock core 6 to push the push block to move toward the position of the linkage sleeve 2, so that the clutch ejector pin 52 fixed to the push block pushes the steel ball 51 to the linkage sleeve 2 and the clutch part 32 to engage, so that the linkage sleeve 2 and the clutch part 32 are linked, when the knob part 3 is rotated, the clutch part 32 drives the linkage sleeve 2 to rotate, so that the transmission part 22 rotates, and the function of unlocking is realized; when the second clutch hole 323, the second linkage hole 202 and the slideway 101 are coaxial, the steel ball 51 can be attracted by the magnetic block 522, and when the eccentric block 61 rotates to the side away from the slideway 101, the steel ball 51 is driven by the clutch ejector pin 52 into the slideway 101, so that the linkage sleeve 2 and the clutch part 32 are separated.

[0084] The embodiment of the present application also discloses an electronic lock body having a lock body idling clutch mechanism.

[0085] An electronic lock comprises a lock body idling clutch structure.

[0086] The implementation principle of an electronic lock body with a lock body idle clutch mechanism in the embodiment of the present application is as follows: when there is electricity, the lock bolt 41 can be inserted into the first clutch hole 322 and the first linkage hole 201 by controlling the rotation of the motor 42, thereby realizing the linkage between the knob member 3 and the linkage sleeve 2, so that when the knob member 3 is rotated, the transmission member 22 also rotates synchronously with the linkage sleeve 2 to realize the unlocking function; when the lock bolt 41 is located in the clutch part 32 and the steel ball 51 is located in the slideway 101, since the clutch part 32 and the linkage sleeve 2 can rotate independently of each other, it can be realized that when the knob member 3 is rotated, the transmission member 22 will not be driven by the linkage sleeve 2 to realize the rotation. When the transmission member 22 is fixed at one end away from the linkage sleeve 2, the transmission member 22 is not easily twisted to cause deformation or damage; when the motor 42 fails in a power outage, the lock can be unlocked by a key, specifically by inserting the key into the keyhole 62 and turning the key, thereby driving the mechanical lock cylinder 6 to rotate, so that the eccentric block 61 pushes the limit block 521 to move, so that the clutch ejector pin 52 fixed to the limit block 521 pushes the steel ball 51 to move in the direction of the clutch part 32, and when the steel ball 51 is stuck in the second linkage hole 202 and the second clutch hole 323, the knob member 3 is linked with the linkage sleeve 2 to drive the rotation of the transmission member 22, thereby realizing the unlocking function.

[0087] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
