[0002] At present, electronic locks generally include a front handle (front panel), a rear handle (rear panel) and a mechanical lock body. The front handle and the rear handle are mainly used to drive the movement of the lock tongue in the mechanical lock body, thereby unlocking or locking. It is more common to set a clutch mechanism in the front handle. This front handle generally sets the drive motor on the side of the clutch mechanism, and uses an arc-shaped push plate to push the clutch pin of the clutch mechanism. This usually requires a wider space for installation. Therefore, the current front handle is mainly composed of a panel and a handle body that is rotatably installed on the door panel. A wide panel is used for the installation of the clutch mechanism and the drive motor. However, this will result in larger sizes for the front handle and the rear handle, making it difficult to apply to some scenarios such as limited door space, and the production and transportation costs are also high.

[0049] The utility model provides a door lock handle.
[0050] In the embodiment of the present utility model, Figures 1 to 18 As shown, the door lock handle includes a fixed seat 10, a handle body 20, a clutch seat 30, a limit member 40 and a driving mechanism 50. The fixed seat 10 is provided with a first through hole 11; the handle body 20 is rotatably mounted on the fixed seat 10, and is provided with a mounting position 21 and a second through hole 28 passing through the mounting position 21, and the second through hole 28 is arranged corresponding to the first through hole 11.
[0051] The clutch seat 30 is rotatably mounted on the mounting position 21. The clutch seat 30 is provided with an axial hole 32. The axial hole 32 corresponds to the second through hole 28. The rotation axis of the clutch seat 30 extends along the hole depth direction of the axial hole 32. The clutch seat 30 is provided with a clamping hole 31. The clamping hole 31 has two limiting walls 311 distributed and opposite to each other along the circumference of the clutch seat 30.
[0052] The limit member 40 is slidably installed on the handle body 20 along the depth direction of the shaft hole 32, and has a linkage state of extending into the clamping hole 31 and a separation state of exiting the clamping hole 31; the driving mechanism 50 is installed on the handle body 20 and is drivingly connected to the limit member 40.
[0053] Specifically, the handle body 20 includes a mounting portion 261 and a grip portion 262, one end of the grip portion 262 is connected to the mounting portion 261, and a second through hole 28 is provided at one end of the mounting portion 261 away from the handle portion, the clutch seat 30 and the stopper 40 are both provided in the mounting portion 261, and the fixing seat 10 is located at a side of the mounting portion 261 away from the grip portion 262. The shaft hole 32 is exposed to the outside through the first through hole 11 and the second through hole 28 for the intermediate shaft to be plugged in (the intermediate shaft is the shaft connecting the door lock handle and the lock body, also called a square shaft, square core, square rod, square stick, etc.).
[0054] When the door lock handle is installed on the door body, it can be fixed on the door body through the fixing seat 10, and the square shaft passes through the first through hole 11 and the second through hole 28 and extends into the shaft hole 32. The hole depth direction of the shaft hole 32 is the extension direction of the rotation axis of the clutch seat 30. The driving mechanism 50 drives the limiter 40 to switch between the separation state and the linkage state. In the linkage state, the clutch seat 30 and the handle body 20 can be connected through the limiter 40, so that when the handle body 20 is rotated, the clutch seat 30 and the square shaft inserted into the shaft hole 32 can be driven to rotate together, thereby realizing unlocking or anti-locking. When the limiter 40 moves from the linkage state to the separation state, the clutch seat 30 is not restricted. At this time, the clutch seat 30 cannot be driven to rotate when the handle body 20 is rotated. Compared to the method in which the limit member 40 is slidably installed on the handle body 20 along a direction perpendicular to the rotation axis of the clutch seat 30, the limit member 40 is slidably installed on the handle body 20 along the extension direction of the rotation axis of the clutch seat 30. This can make full use of the space in the handle body 20 along the extension direction of the rotation axis of the clutch seat 30, and reduce the space occupied by the limit member 40 in the direction perpendicular to the rotation axis of the clutch seat 30.
[0055] The technical solution of the utility model is that when the clutch seat 30 is arranged in the handle body 20, the limiting member 40 is slidably installed on the handle body 20 along the hole depth direction of the shaft hole 32, and the limiting member 40 has a linkage state of extending into the clamping hole 31 of the clutch seat 30 and a separation state of exiting the clamping hole 31 of the clutch seat 30. In this way, when the limiting member 40 is driven by the driving mechanism 50 to move to the linkage state, the limiting member 40 connects the clutch seat 30 and the handle body 20, so that when the handle body 20 is rotated, the clutch seat 30 and the square shaft inserted into the shaft hole 32 can be driven to rotate together to achieve unlocking or anti-locking. Compared with the manner in which the limit member 40 is slidably installed on the handle body 20 along a direction perpendicular to the rotation axis of the clutch seat 30, the limit member 40 is slidably installed on the handle body 20 along the extension direction of the rotation axis of the clutch seat 30. This can make full use of the space inside the handle body 20 along the extension direction of the rotation axis of the clutch seat 30, reduce the space occupied by the limit member 40 in the direction perpendicular to the rotation axis of the clutch seat 30, avoid the partial size (the size in the direction perpendicular to the rotation axis of the clutch seat 30) of the clutch seat 30 and the limit member 40 installed on the handle body 20 being too large, and at the same time, the size of the fixed seat 10 can be made smaller, avoiding the situation where the traditional front panel has a wide panel, and can effectively reduce the size of the door lock handle, thereby reducing the production materials and packaging volume, which is beneficial to reducing production costs and transportation costs.
[0056] In some embodiments, a limiting portion 22 is provided in the handle body 20, the limiting portion 22 is located at one side of the installation position 21, and has a limiting groove 221 extending to the installation position 21, the clamping hole 31 penetrates the circumference of the clutch seat 30, and is arranged corresponding to the limiting groove 221, and the limiting member 40 has a limiting rod 42, and in the linkage state, the limiting rod 42 extends into the limiting groove 221 and the clamping hole 31. In this way, when the limiting member 40 is in the linkage state and the handle body 20 is rotated, the limiting portion 22 can be mainly subjected to force, and the limiting member 40 can be limited, which can improve the stability and reliability of the limiting member 40. Of course, in other embodiments, the orifice of the clamping hole 31 can also be arranged on the surface of the clutch seat 30 away from the fixed seat 10, and spaced from the circumference of the clutch seat 30.
[0057] In some embodiments, the mounting position 21 is provided with a mounting groove 211, the clutch seat 30 is rotatably mounted in the mounting groove 211, the limiting groove 221 passes through the groove side wall of the mounting groove 211, and the second through hole 28 passes through the groove bottom wall of the mounting groove 211. In this way, the clutch seat 30 can be effectively limited, and the installation stability of the clutch seat 30 can be improved, so that when the handle body 20 is rotated, the clutch seat 30 can be stably rotated. In addition, in other embodiments, a convex ring can also be provided at the mounting position 21, and an annular groove cooperating with the convex ring can be provided on the clutch seat 30, and the centers of the convex ring and the annular groove are both located on the rotation axis of the clutch seat 30.
[0058] In some embodiments, the door lock handle further includes a limit cover plate 7427, which covers the side of the clutch seat 30 away from the fixed seat 10 to limit the clutch seat 30 to the installation position 21. The limit cover plate 7427 is provided with an avoidance gap at the position corresponding to the clamping hole 31 to allow the limit member 40 to pass through. That is, after the clutch seat 30 is installed at the installation position 21, the limit cover plate 7427 is covered on the side of the clutch seat 30 away from the fixed seat 10, and the limit cover plate 7427 is spaced from the clutch seat 30 to prevent the limit cover plate 7427 from limiting the normal rotation of the clutch seat 30. At this time, the limit cover plate 7427 mainly limits the clutch seat 30 to move in the direction away from the fixed seat 10. In this way, the clutch seat 30 can be ensured to be stable and reliable when rotating, and the drive mechanism 50 and other components can be easily installed after the clutch seat 30 is installed.
[0059] In some embodiments, the mounting position 21 is provided with two stoppers 212, and the two stoppers 212 are spaced apart in the circumferential direction of the second through hole 28. The clutch seat 30 is provided with a limiting protrusion 33, and the limiting protrusion 33 is located between the two stoppers 212, and any of the stoppers 212 is located on the movement path when the clutch seat 30 rotates. When the limiting member 40 extends into the clamping hole 31, the limiting protrusion 33 is spaced apart from at least one of the stoppers 212. That is, when the limiting protrusion 33 abuts against any of the stoppers 212, it is spaced apart from the other stoppers 212 by a certain distance, so that the handle body 20 can be normally rotated to unlock, while preventing the handle from excessively rotating.
[0060] In some embodiments, the clutch seat 30 is provided with three latching holes 31, and the three latching holes 31 are distributed at intervals along the circumference of the clutch seat 30; two of the latching holes 31 are opposite to each other and are arranged on opposite sides of the rotation axis of the clutch seat 30, and the limiting protrusion 33 is located at one of the two relative latching holes 31, so that when the limiting member 40 extends into one of the two relative latching holes 31, the limiting protrusion 33 is close to or abuts against one stop portion 212, and is spaced from the other stop portion 212; when the limiting member 40 extends into the remaining latching hole 31, the limiting protrusion 33 is spaced between the two stop portions 212.
[0061] For the convenience of explanation, two clamping holes 31 that are opposite and disposed on opposite sides of the rotation axis of the clutch seat 30 are defined as first clamping holes 312, and the other clamping hole 31 is defined as second clamping hole 313. That is, when the limiting member 40 extends into one of the two first clamping holes 312, the limiting protrusion 33 is close to or abuts against one of the anti-rotation parts 212, and is spaced from the other anti-rotation part 212; when the limiting member 40 extends into the second clamping hole 313, the limiting protrusion 33 is spaced between the two anti-rotation parts 212.
[0062] In this way, when the lock body 80 with the lifting anti-locking function is matched, the corresponding first locking hole 312 can be selected to be matched with the limiting member 40 according to the door opening direction, so that when the handle body 20 is in the initial state, the limiting protrusion 33 is close to or abuts one anti-rotation portion 212, and is separated from the other anti-rotation portion 212. At this time, by lifting the handle body 20, the limiting protrusion 33 can be abutted against the corresponding anti-rotation portion 212, thereby driving the clutch seat 30 to rotate, and then driving the anti-locking tongue of the lock body 80 to lock through the clutch seat 30. When the limiting member 40 is in the separated state, if the handle body 20 is pressed down, the handle body 20 will rotate relative to the clutch seat 30, and cannot drive the lock tongue of the lock body 80 to move.
[0063] When the lock body 80 without the upward anti-locking function is matched, the second clamping hole 313 is matched with the limiting member 40. In this way, when the limiting member 40 is in the linkage state of being clamped into the second clamping hole 313, the clutch seat 30 can be driven to rotate in the positive direction (relative to the "reverse direction" described below) by pressing the handle body 20 downward, thereby driving the lock tongue of the lock body 80 to unlock. If the limiting member 40 is in the separated state, the handle body 20 can be made to rotate idly regardless of whether the handle body 20 is lifted or pressed downward. In this way, the door lock handle can be compatible with a variety of lock bodies 80, increasing the scope of application of the door lock handle.
[0064] In some embodiments, the driving mechanism 50 includes a main control board, a motor 51 and a transmission mechanism 52. The motor 51 is electrically connected to the main control board and is transmission-connected to the stopper 40 through the transmission mechanism 52. In this way, electric unlocking can be achieved, which is convenient for users.
[0065] In other embodiments, the drive mechanism 50 includes a lock core mechanism 53, which has a key hole 532 and a toggle member 531. The toggle member 531 is located on a side of the limiter 40 away from the fixing seat 10, and is used to push the limiter 40 from the separated state to the linked state. The handle body 20 is provided with a clearance hole 23 at a position corresponding to the key hole 532. In this way, the user can manually unlock the lock by using a key.
[0066] In some embodiments, the driving mechanism 50 includes a lock core mechanism 53, a motor 51 and a transmission mechanism 52. The motor 51 is connected to the limiter 40 through the transmission mechanism 52. The lock core mechanism 53 has a key hole 532 and a toggle 531. The toggle 531 is located on the side of the limiter 40 away from the fixing seat 10, and is used to push the limiter 40 from the separated state to the linked state. The handle body 20 is provided with a clearance hole 23 at a position corresponding to the key hole 532. In this way, the user can rotate the lock by key or electric unlocking, which is convenient for the user to use.
[0067] In some embodiments, the limiting member 40 includes a sliding seat 41 and a limiting rod 42 connected to the sliding seat 41, the sliding seat 41 is provided with a groove 411 and a mounting hole 412, and the mounting hole 412 penetrates two opposite side walls of the groove 411; the transmission mechanism 52 includes a transmission rod 521 and a coil spring 523, one end of the transmission rod 521 is connected to the rotating shaft of the motor 51, and is movably arranged in the mounting hole 412, the portion of the transmission rod 521 located in the groove 411 is provided with a lever 522, the coil spring 523 is sleeved on the transmission rod 521, and abuts between two opposite side walls of the groove 411, and the lever 522 penetrates between two adjacent sections of the coil spring 523. That is, when the motor 51 drives the transmission rod 521 to rotate, the lever 522 can be moved between the coil spring 523, so that the coil spring 523 moves along the length direction of the transmission rod 521, thereby pushing the limiting member 40 to slide through the coil spring 523. Such a structure is simple and can avoid rigid transmission between the motor 51 and the limiting member 40. Of course, in other embodiments, the transmission mechanism 52 can also adopt gear rack transmission or screw nut transmission.
[0068] In some embodiments, the toggle member 531 is located on the side of the limit rod 42 away from the fixed seat 10, and is used to push the limit member 40 from the separated state to the linked state; in this way, when the toggle member 531 pushes the limit member 40 from the separated state to the linked state, the coil spring 523 can be compressed. When the key is reset after unlocking, the limit member 40 can be automatically reset to the linked state under the action of the coil spring 523. In this way, the coil spring 523 is used to realize the automatic reset of the limit member 40 after the key is unlocked, which can simplify the structure of the door lock handle.
[0069] In some embodiments, the door lock handle further includes at least one of a fingerprint module 61 and a password input module 62, and both the fingerprint module 61 and the password input module 62 are electrically connected to the main control board. Specifically, the password input module 62 can be a key module or a touch screen module, that is, the password input module 62 can realize password input through mechanical keys or through touch. This allows for more unlocking methods, which is convenient for users.
