Description

Technical Field

[0001] This utility model relates to the field of smart lock technology, and in particular to a smart lock body structure. Background Technology

[0002] With the rapid development of smart home technology, smart locks, with their convenience and security features, are gradually becoming the mainstream choice for door locks in homes and offices. Smart locks are usually equipped with handles to allow for manual unlocking in case of electronic system failure or user needs. This mechanical unlocking method provides users with additional security and an emergency unlocking method.

[0003] However, in actual use, smart lock handles face a series of problems. Due to frequent daily use, handles are subjected to various external forces, and after prolonged use, they are prone to loosening or even breakage. Once these problems occur, the handle needs to be replaced promptly to ensure the normal use and security of the smart lock. Currently, most smart lock handles on the market are fixed to the lock body with screws. This method requires specific tools such as screwdrivers and hex wrenches to disassemble the handle. For ordinary users, in an emergency, it is often difficult to quickly find suitable tools, and the operation process is relatively cumbersome, requiring a certain level of hands-on ability. This significantly reduces the convenience of handle replacement and fails to meet users' needs for rapid repair and replacement. There are obvious shortcomings in terms of user experience and operational efficiency, necessitating further improvement and optimization. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a smart lock body structure that is easy to assemble and disassemble.

[0005] A smart lock body structure designed for this purpose includes a housing and a handle. The housing is rotatably provided with a rotating component for connection with a shaft. The handle is provided with a connecting sleeve, which is inserted into the rotating component.

[0006] The rotating component is provided with a mounting cavity, the mounting cavity is provided with a locking module, the connecting sleeve is provided with a locking hole, and the locking module can be inserted into the locking hole;

[0007] The locking module includes a mounting bracket disposed within the mounting cavity, and a plurality of locking pins are arranged in a circumferential array on the mounting bracket; the rotating component is provided with a positioning hole corresponding to the locking hole, and the locking pins are movable relative to the mounting bracket and can pass through the positioning hole to be inserted into the locking hole or disengaged from the locking hole;

[0008] The locking pin is connected to a first elastic element, which is used to drive the locking pin out of the locking hole;

[0009] The mounting bracket is provided with a conical drive head that moves back and forth relative to the mounting bracket. When the conical drive head is in the first position, the conical drive head pushes the locking pin to remain inserted in the locking hole.

[0010] The conical drive head is connected to a second elastic element, which is used to drive the conical drive head to remain in the first position.

[0011] The handle has a control hole at the position corresponding to the conical drive head.

[0012] Preferably, the mounting bracket is provided with a guide post, the conical drive head is provided with a guide hole, and the guide post is movably inserted into the guide hole;

[0013] The guide post is provided with a countersunk hole, and a bolt threadedly connected to the guide post passes through the countersunk hole; the bolt is movable relative to the countersunk hole.

[0014] Preferably, the second elastic element is disposed within the guide hole.

[0015] Preferably, the mounting bracket is provided with a mounting hole corresponding to the position of the positioning hole, and the locking pin is movably disposed in the mounting hole;

[0016] The first elastic element is a spring. One end of the first elastic element is connected to the mounting bracket, and the other end is connected to the locking pin and sleeved on the first elastic element of the locking pin.

[0017] Preferably, the outer surface of the rotating component is provided with multiple limiting grooves arranged in a circumferential array, and the connecting sleeve is provided with limiting ribs that are inserted into the limiting grooves.

[0018] Compared with existing technologies, this utility model's intelligent lock body structure, through innovative design, effectively overcomes the technical problem of inconvenient handle replacement in existing intelligent locks, and has significant beneficial effects. The rotating component of the housing and the handle connecting sleeve are connected by a plug-in joint. Combined with the design of the locking module, compared to traditional screw fixing methods, no screwdrivers, hex wrenches, or other tools are needed. Users only need to operate the conical drive head through the control hole on the handle. When the conical drive head moves away from the first position, the locking pin can quickly disengage from the locking hole under the action of the first elastic element, achieving quick handle removal. During installation, after plugging the connecting sleeve into the rotating component, the conical drive head returns to the first position under the action of the second elastic element, pushing the locking pin into the locking hole, completing quick installation. This greatly improves the convenience and efficiency of handle replacement, reduces the operational difficulty, and allows even ordinary users to easily complete the handle replacement operation.

[0033] See Figures 1-6 A smart lock body structure includes a housing 10 and a handle 20. The housing 10 is rotatably provided with a rotating component 30 for connection with a shaft 40. The handle 20 is provided with a connecting sleeve 210, which is inserted into the rotating component 30.

[0034] The rotating component 30 is provided with a mounting cavity 310, the mounting cavity 310 is provided with a locking module 50, the connecting sleeve 210 is provided with a locking hole 220, and the locking module 50 can be inserted into the locking hole 220;

[0035] The locking module 50 includes a mounting bracket 510 disposed in the mounting cavity 310, and a plurality of locking pins 520 are arranged in a circumferential array on the mounting bracket 510; the rotating member 30 is provided with a positioning hole 300 corresponding to the locking hole 220, and the locking pins 520 are movable relative to the mounting bracket 510 and can pass through the positioning hole 300 to be inserted into the locking hole 220 or disengaged from the locking hole 220;

[0036] The locking pin 520 is connected to a first elastic element 530, which is used to drive the locking pin 520 out of the locking hole 220.

[0037] The mounting bracket 510 is provided with a conical drive head 540 that moves back and forth relative to the mounting bracket 510. When the conical drive head 540 is in the first position, the conical drive head 540 pushes the locking pin 520 to remain inserted in the locking hole 220.

[0038] The conical drive head 540 is connected to a second elastic element 560, which is used to drive the conical drive head 540 to remain in a first position.

[0039] The handle 20 is provided with a control hole 200 at the position corresponding to the conical drive head 540.

[0040] The operating principle of this invention is as follows: During disassembly, the user only needs to operate the conical drive head through the control hole of the handle. When the conical drive head moves away from the first position, the locking pin can quickly disengage from the locking hole under the action of the first elastic element, realizing the quick disassembly of the handle. During installation, after inserting the connecting sleeve and the rotating part, the conical drive head returns to the first position under the action of the second elastic element, pushing the locking pin into the locking hole to complete the quick installation. This greatly improves the convenience and efficiency of handle replacement, reduces the difficulty of operation, and allows even ordinary users to easily complete the handle replacement operation.

[0041] The force of the second elastic element 560 is greater than the force of the first elastic element 530. The purpose of this design is that when the conical drive head is reset to the first position, the conical drive head needs to push the locking pin to compress the first elastic element so that the locking pin is inserted into the locking hole.

[0042] See Figure 4The mounting bracket 510 is provided with a guide post 320, and the conical drive head 540 is provided with a guide hole 550. The guide post 320 is movably inserted into the guide hole 550. The guide post 320 is provided with a countersunk hole 330, and a bolt 570 threadedly connected to the guide post 320 passes through the countersunk hole 330. The bolt 570 is movable relative to the countersunk hole 330. The cooperation between the guide post 320 and the guide hole 550 can constrain the movement of the conical drive head 540, allowing it to move only in a straight line relative to the mounting bracket 510. Under the action of its straight-line movement, the conical surface of the conical drive head 540 can push the locking pin 520 to move. The bolt 570 serves to constrain the position of the conical drive head 540, preventing it from separating from the mounting bracket 510.

[0043] See Figure 4 The second elastic element 560 is disposed within the guide hole 550. The second elastic element 560 is a spring and is sleeved on the bolt 570.

[0044] See Figure 4 and Figure 6 The mounting bracket 510 is provided with a mounting hole 511 corresponding to the position of the positioning hole 300, and the locking pin 520 is movably disposed in the mounting hole 511; the first elastic element 530 is a spring, one end of the first elastic element 530 is connected to the mounting bracket 510, and the other end is connected to the locking pin 520 and sleeved on the first elastic element 530 of the locking pin 520.

[0045] See Figure 4 The outer surface of the rotating component 30 is provided with multiple limiting grooves 340 arranged in a circumferential array, and the connecting sleeve 210 is provided with limiting ribs 230 that insert into the limiting grooves 340. The limiting ribs 230 and the limiting grooves 340 are engaged to enable the rotating component 30 to rotate through the connecting sleeve 210 when the handle 20 is rotated, thereby driving the shaft 30 to rotate.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
