Abstract
Description
Technical Field
[0001] This utility model relates to the field of lock technology, and in particular to a door lock handle and an electronic lock. Background Technology
[0002] Currently, electronic locks generally consist of a front handle, a rear handle, and a mechanical lock body. The front and rear handles are mainly used to move the bolt in the mechanical lock body, thereby unlocking or locking. Currently, it is common to set the clutch mechanism in the base of the front handle, but this results in a relatively large front handle size, making it difficult to use in some scenarios such as when there is limited space in the door. Utility Model Content
[0003] The main purpose of this utility model is to provide a door lock handle that aims to reduce the size of the door lock handle.
[0004] To achieve the above objectives, the door lock handle proposed in this utility model includes:
[0005] The fixing base is provided with a through hole and a limiting hole located on one side of the through hole;
[0006] The drive shaft is rotatably mounted in the through hole;
[0007] The handle body includes a mounting portion and a grip portion. The grip portion is connected to one end of the mounting portion and extends laterally toward the mounting portion. The mounting portion has a connecting portion and a mounting hole at the end away from the grip portion. The drive shaft is fixed to the connecting portion.
[0008] The driving mechanism includes a limiting rod and a driving motor for driving the limiting rod to move. The driving motor is located on the grip portion. The limiting rod is movably installed in the mounting hole and has a locked state and an unlocked state. In the locked state, the limiting rod extends into the limiting hole to restrict the rotation of the handle body relative to the fixed base. In the unlocked state, the limiting rod retracts out of the limiting hole.
[0009] Optionally, the drive mechanism further includes a cam and a reset member. The cam is mounted on the shaft of the drive motor and abuts against the end of the limit rod away from the limit hole. The reset member cooperates with the limit rod to drive the limit rod to move toward the unlocked state.
[0010] Optionally, the cam has a convex arc surface, a flat surface, and a limiting protrusion on its periphery. The flat surface is opposite to the convex arc surface, and the limiting protrusion is located between the convex arc surface and the flat surface. The handle body and the mounting hole have abutment portions on opposite sides. In the locked state, the convex arc surface abuts against the limiting rod, and the limiting protrusion abuts against one of the abutment portions. In the unlocked state, the flat surface abuts against the limiting rod, and the limiting protrusion abuts against the other abutment portion.
[0011] Optionally, the reset member is a compression spring and is sleeved on the limiting rod. The end of the limiting rod away from the limiting hole is provided with a first limiting part, and the mounting hole is provided with a second limiting part. The reset member abuts between the first limiting part and the second limiting part.
[0012] Optionally, the number of limiting holes is two or four, and each limiting hole is evenly spaced along the circumference of the through hole. In the locked state, the limiting rod extends into one of the limiting holes.
[0013] Optionally, the drive shaft includes a handle shaft and a square shaft. The handle shaft is rotatably mounted in the through hole and connected to the connecting part. The handle shaft has a slot on the side opposite to the handle body, and the square shaft is adapted to be inserted into the slot.
[0014] Optionally, the drive shaft further includes a locking screw, the handle shaft has a screw through hole that penetrates the bottom wall of the slot, the locking screw passes through the screw through hole and is screwed to the connecting part to fix the handle shaft to the mounting part.
[0015] Optionally, the door lock handle includes a mounting base, an elastic element, and a limiting element. The mounting base has a mounting through hole and a mounting groove. The mounting groove is located on one side of the mounting through hole and communicates with the mounting through hole. The handle shaft is rotatably mounted on the mounting through hole. The outer circumferential surface of the handle shaft and the area corresponding to the mounting groove are provided with multiple limiting grooves. The multiple limiting grooves are distributed at intervals along the circumference of the handle shaft. The elastic element and the limiting element are both provided in the mounting groove. The elastic element abuts against the side of the limiting element away from the mounting through hole. The limiting element has a convex arc portion at least in the portion facing the mounting through hole, and a portion of the convex arc portion extends into the limiting groove.
[0016] Optionally, the door lock handle further includes a main control board, an unlocking module, and a battery. The unlocking module, the battery, and the drive motor are all electrically connected to the main control board. The unlocking module is exposed on the side of the handle body away from the mounting base.
[0017] This utility model also proposes an electronic lock, including a lock body and a door handle as described above.
[0018] This invention provides a limiting hole on the fixed base next to the transmission shaft, and a limiting rod and a drive motor for moving the limiting rod are installed on the handle body. This allows the limiting rod to have both locked and unlocked states. When locked, the limiting rod extends into the limiting hole, restricting the handle body from rotating relative to the fixed base. This prevents the handle body from driving the transmission shaft and thus the bolt on the lock body, thus achieving locking. When unlocked, the limiting rod retracts out of the limiting hole, allowing the handle body to rotate relative to the fixed base. Rotating the handle body then drives the transmission shaft, which in turn moves the bolt on the lock body, unlocking the lock. This arrangement of the drive mechanism on the handle body simplifies the structure of the fixed base and reduces its size. Furthermore, placing the limiting rod in the mounting section of the handle body and the drive motor in the grip section fully utilizes the space between these sections, avoiding the problem of a concentrated drive mechanism leading to an excessively large handle body. This results in a more balanced size between the mounting and grip sections, further reducing the overall size of the handle body. This reduces the overall size of the door lock handle, making it suitable for doors of various sizes and thus expanding its application range. Attached Figure Description

[0034] This utility model proposes a door lock handle.
[0035] In the embodiments of this utility model, such as Figures 1 to 8 As shown, the door lock handle includes a fixed base 10, a drive shaft 20, a handle body 30, and a drive mechanism 40. The fixed base 10 is provided with a through hole 11 and a limiting hole 12 located on one side of the through hole 11. The drive shaft 20 is rotatably mounted in the through hole 11. The handle body 30 includes a mounting part 31 and a gripping part 32. The gripping part 32 is connected to one end of the mounting part 31 and extends laterally toward the mounting part 31. The end of the mounting part 31 away from the gripping part 32 is provided with a connecting part 311 and a mounting hole 312. The drive shaft 20 is fixed to the connecting part 311.
[0036] The drive mechanism 40 includes a limiting rod 42 and a drive motor 41 for driving the limiting rod 42. The drive motor 41 is located on the grip part 32. The limiting rod 42 is movably mounted in the mounting hole 312 and has a locked state and an unlocked state. In the locked state, the limiting rod 42 extends into the limiting hole 12 to restrict the rotation of the handle body 30 relative to the fixed seat 10. In the unlocked state, the limiting rod 42 retracts out of the limiting hole 12.
[0037] Specifically, the door lock handle also includes a main control board and an unlocking module 50. The unlocking module 50 and the drive motor 41 are both electrically connected to the main control board. The unlocking module 50 includes at least one of a password input panel, a fingerprint recognition module, a Bluetooth module, a Wi-Fi module, and an NFC module. Optionally, the unlocking module 50 is exposed on the side of the handle body 30 away from the mounting base 10 for user operation.
[0038] The fixed base 10 is used to install on the door body, and the drive shaft 20 is used to connect with the transmission structure on the lock body to drive the lock tongue on the lock body to move and unlock.
[0039] The drive motor 41 can drive the limiting rod 42 to move within the mounting hole 312. When the limiting rod 42 extends out of the mounting hole 312 and into the limiting hole 12, the limiting rod 42 is in a locked state. At this time, it can restrict the rotation of the handle body 30 relative to the fixed seat 10, that is, it cannot drive the transmission shaft 20 to rotate through the handle body 30, thereby driving the bolt on the lock body to move, thus achieving locking. When the limiting rod 42 retracts out of the limiting hole 12 and is in an unlocked state, the handle body 30 can rotate relative to the fixed seat 10. Thus, by rotating the handle body 30, the transmission shaft 20 can be driven to rotate, thereby driving the bolt on the lock body to move, thus achieving unlocking.
[0040] This utility model's technical solution involves setting a limiting hole 12 on the fixed base 10 and beside the transmission shaft 20, and setting a limiting rod 42 and a drive motor 41 for driving the limiting rod 42 on the handle body 30. This allows the limiting rod 42 to have both a locked and an unlocked state. When the limiting rod 42 is in the locked state, it extends into the limiting hole 12, restricting the rotation of the handle body 30 relative to the fixed base 10. This prevents the drive shaft 20 from rotating, thus preventing the movement of the bolt on the lock body and achieving locking. When in the unlocked state, the limiting rod 42 retracts out of the limiting hole 12, allowing the handle body 30 to rotate relative to the fixed base 10. Rotating the handle body 30 then drives the drive shaft 20, which in turn moves the bolt on the lock body, unlocking the lock. By placing the drive mechanism 40 on the handle body 30, the structure of the fixed base 10 is simplified, and its size is reduced. Furthermore, by placing the limiting rod 42 in the mounting portion 31 of the handle body 30 and the drive motor 41 in the grip portion 32, the space between the mounting portion 31 and the grip portion 32 can be fully utilized. This avoids the situation where the drive mechanism 40 is concentrated in one part, resulting in an excessively large size of the handle body 30. This allows for a more balanced size between the mounting portion 31 and the grip portion 32, which is beneficial for reducing the size of the handle body 30. In other words, the overall size of the door lock handle can be reduced, making it suitable for various door sizes and thus expanding its application range.
[0041] In some embodiments, the drive mechanism 40 further includes a cam 43 and a reset member 44. The cam 43 is mounted on the shaft of the drive motor 41 and abuts against the end of the limiting rod 42 away from the limiting hole 12. The reset member 44 cooperates with the limiting rod 42 to drive the limiting rod 42 to move towards the unlocked state. That is, when the cam 43 rotates to the end of its protrusion abutting against the limiting rod 42, it can drive the limiting rod 42 to move to the locked state. When the cam 43 rotates to the end of its protrusion away from the limiting rod 42, the reset member 44 drives the limiting rod 42 to move to the unlocked state. This simplifies the structure of the drive mechanism 40, which helps to reduce the size of the handle body 30 and lower production costs. Of course, in other embodiments, a crank-rocker mechanism or other mechanism that can convert rotational motion into linear motion can also be provided between the limiting rod 42 and the drive motor 41.
[0042] Optionally, the reset member 44 is a compression spring and is sleeved on the limiting rod 42. The end of the limiting rod 42 away from the limiting hole 12 has a first limiting portion 421, and the mounting hole 312 has a second limiting portion 313. The reset member 44 abuts between the first limiting portion 421 and the second limiting portion 313. This structure is simple and reliable, and can extend the service life of the drive mechanism 40. Of course, in other embodiments, the reset member 44 is a tension spring and is connected between the limiting rod 42 and the mounting portion 31.
[0043] In some embodiments, the cam 43 has a convex arc surface 431, a flat surface 432, and a limiting protrusion 433 on its periphery. The flat surface 432 is opposite to the convex arc surface 431, and the limiting protrusion 433 is located between the convex arc surface 431 and the flat surface 432. Abutment portions are provided on opposite sides of the handle body 30 and the mounting hole 312. In the locked state, the convex arc surface 431 abuts against the limiting rod 42, and the limiting protrusion 433 abuts against one of the abutment portions. In the unlocked state, the flat surface 432 abuts against the limiting rod 42, and the limiting protrusion 433 abuts against the other abutment portion. Specifically, the limiting protrusion 433 is located between one side of the convex arc surface 431 and the flat surface 432, and the other side of the convex arc surface 431 and the flat surface 432 are arranged with an arc transition to ensure that the limiting rod 42 moves more smoothly between the locked and unlocked states. The setting of the limiting protrusion 433 can prevent the cam 43 from rotating excessively, and can keep the limiting rod 42 accurately and stably in the locked / unlocked state.
[0044] In some embodiments, the number of limiting holes 12 is multiple (e.g., two or four), and each limiting hole 12 is evenly spaced along the circumference of the through hole 11. In the locked state, the limiting rod 42 extends into one limiting hole 12. Specifically, when there are two limiting holes 12, the two limiting holes 12 are respectively located on opposite sides of the through hole 11; when there are four limiting holes 12, the four limiting holes 12 are evenly spaced along the circumference of the through hole 11, and the distance between any two adjacent limiting holes 12 is the same. With this configuration, it is not necessary to distinguish between the front and back, so that the door lock handle can be used for both right-opening and left-opening doors. When there are four limiting holes 12, the position of the fixing base 10 can also be adjusted according to the actual state of the door, so that the door lock handle can adapt to various installation environments.
[0045] In some embodiments, the connecting portion 311 is provided with a connecting groove, and the drive shaft 20 is provided with a plug-in portion 211 that engages with the connecting groove, thus facilitating installation. In other embodiments, the connecting portion 311 is provided with a connecting protrusion, and the drive shaft 20 is provided with a plug-in groove, into which the connecting protrusion is plugged.
[0046] In some embodiments, the drive shaft 20 includes a handle shaft 21 and a square shaft 22. The handle shaft 21 is rotatably mounted in the through hole 11 and connected to the connecting part 311. A slot 212 is provided on the side of the handle shaft 21 facing away from the handle body 30, and the square shaft 22 is adapted to be inserted into the slot 212. With this configuration, during packaging, the handle shaft 21 can be fixed to the fixing base 10, while the square shaft 22 can be separated from the handle shaft 21, which can reduce the size of the door lock handle along the axial direction of the handle shaft 21, thereby reducing the packaging size and facilitating transportation packaging. During installation, it is only necessary to insert the square shaft 22 into the slot 212, making installation convenient. Of course, in other embodiments, the drive shaft 20 can also be designed as a single piece.
[0047] In some embodiments, the drive shaft 20 further includes a locking screw 23, and the handle shaft 21 has a screw through hole 213 that penetrates the bottom wall of the slot 212. The locking screw 23 passes through the screw through hole 213 and is screwed onto the connecting portion 311 to fix the handle shaft 21 to the mounting portion 31. This ensures a reliable connection between the handle body 30 and the handle shaft 21, while also allowing the locking screw 23 to be hidden inside, facilitating waterproofing and improving the appearance. In some embodiments, the handle shaft 21 has a plug-in portion 211, which is a non-rotational structure (such as a prism, elliptical cylinder, or irregularly shaped cylinder). The shape of the connecting groove corresponds to the shape of the plug-in portion 211 to prevent the plug-in portion 211 from rotating within the connecting groove. Of course, in other embodiments, screw holes can also be provided on the side of the mounting portion 31, through which the locking screw 23 is screwed onto the handle shaft 21.
[0048] In some embodiments, the door lock handle includes a mounting base 61, an elastic element 62, and a limiting element 63. The mounting base 61 has a mounting through hole 611 and a mounting groove 612. The mounting groove 612 is located on one side of the mounting through hole 611 and communicates with the mounting through hole 611. The handle shaft 21 is rotatably mounted in the mounting through hole 611. The outer circumferential surface of the handle shaft 21 and the area corresponding to the mounting groove 612 are provided with a plurality of limiting grooves 214. The plurality of limiting grooves 214 are distributed at intervals along the circumference of the handle shaft 21. The elastic element 62 and the limiting element 63 are both provided in the mounting groove 612. The elastic element 62 abuts against the side of the limiting element 63 away from the mounting through hole 611. The limiting element 63 has a convex arc portion at least in the portion facing the mounting through hole 611, and a portion of the convex arc portion extends into the limiting groove 214. This configuration can increase the resistance to the rotation of the handle shaft 21, preventing the handle body 30 from driving the transmission shaft 20 to rotate under the action of gravity when the lock is open. Optionally, the handle shaft 21 is provided with elastic elements 62 and limiting elements 63 on both opposite sides to ensure that the handle shaft 21 is subjected to uniform force. Optionally, the limiting element 63 is a ball.
[0049] In some embodiments, the door lock handle also includes a battery 71, which is electrically connected to the main control board. This allows the battery 71 to power the drive motor 41 and the unlocking module 50, eliminating the need for additional wiring. Of course, in other embodiments, an external power supply can be used via a power cord.
[0050] Optionally, the handle body 30 is also provided with a charging interface 72, which is electrically connected to the charging circuit on the main control board for charging the battery 71 with an external power source. Of course, in other embodiments, the battery 71 is designed to be detachable.
[0051] This utility model also proposes an electronic lock, which includes a lock body and a door handle. The specific structure of the door handle is as described in the above embodiments. Since this electronic lock adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The lock body is used to install on the door, and the lock body is provided with a bolt and a transmission structure connecting the bolt. During installation and use, the transmission shaft 20 on the door handle is connected to the transmission structure on the lock body, so that the bolt can be driven to move through the transmission shaft 20 and the transmission structure to achieve unlocking. In some embodiments, the transmission structure has a square shaft 22 hole for the square shaft 22 on the door handle to be inserted and fitted.
[0052] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
