Description

Technical Field

[0001] This invention relates to the field of lock technology, specifically to a five-stage reducer for a motor lock body. Background Technology

[0002] In the field of motor lock bodies, the motor reducer is the core transmission component that realizes the locking and unlocking actions of the lock body. Its performance and the way it cooperates with surrounding components directly determine the overall operational stability, structural rationality and production assembly efficiency of the motor lock body.

[0003] In existing technologies, the motor reducer, unlocking position detection switch, unlocking reset position detection switch, and motor drive control circuit board of the motor lock body are all installed in different locations inside the lock body in a distributed layout. This distributed layout results in extremely low internal space utilization and a chaotic component arrangement. Because the functional components are scattered, separate installation and wiring space must be reserved for each component. This not only makes it difficult to optimize the size of the main lock body components, failing to meet the market demand for miniaturized lock bodies, but also weakens the structural strength of the main lock body components due to the unreasonable internal structural layout, reducing the lock body's impact and damage resistance, and affecting its service life. Secondly, the production and assembly are more difficult. The distributed layout requires operators to position, install, and wire each component separately, making the assembly process cumbersome and requiring higher assembly precision. This not only reduces production and assembly efficiency but also easily leads to poor fit between components due to assembly errors. At the same time, the distributed components require more fixing structures and connecting wires, increasing the number of parts and further increasing the production and manufacturing costs of the lock body and subsequent maintenance costs. Summary of the Invention

[0004] This invention provides a five-stage reducer for a motor lock body, which solves the problem that the motor reducer, the unlocking position detection switch, the unlocking reset position detection switch, and the motor drive control circuit board are all installed in different positions inside the lock body in a distributed layout.

[0005] This invention provides a five-stage reducer for a motor lock body, comprising:

[0006] A housing having a first mounting cavity inside; A five-stage reduction gear set is disposed in the first mounting cavity and meshes with a motor; A position detection component is disposed within the first mounting cavity; The cover is fixedly disposed on the top of the housing.

At the same time, the integrated design simplifies the production and assembly process. Operators only need to position and install the overall component, eliminating the need for tedious assembly procedures for each small component individually. This reduces assembly difficulty, improves production and assembly efficiency, and reduces component misalignment problems caused by assembly errors. In addition, the integrated design reduces the amount of fixing structures and connecting wires used, lowering component costs and thus reducing the production and manufacturing costs of the lock body and subsequent maintenance costs.

The fifth gear shaft passes through the fifth gear shaft hole and is disposed in the first mounting cavity.

[0019] Beneficial effects: By installing a first gear shaft, a second gear shaft, a third gear shaft, a fourth gear shaft, and a fifth gear shaft within the first mounting cavity, and then fitting the first, second, third, fourth, and fifth gears onto these shafts respectively, a stable installation and precise transmission of the five-stage reduction gear set are achieved. Simultaneously, the first, second, third, fourth, and fifth gear shaft holes on the housing provide stable support points for the gear shafts, ensuring the stability and reliability of the gears during rotation.

This ensures the stability and reliability of the five-stage reduction gear set transmission, avoids problems such as poor gear meshing and transmission jamming caused by the axial movement of the fifth gear, and further improves the overall performance and service life of the motor lock body five-stage reducer.

[0022] In one optional embodiment, the cover has a first gear shaft blind hole, a second gear shaft blind hole, a third gear shaft blind hole, a fourth gear shaft blind hole, and a fifth gear shaft hole.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0031] According to an embodiment of the present invention, a five-stage reducer for a motor lock body is provided, comprising: a housing 1, a five-stage reduction gear set 2, a position detection component 4, and a cover 5. The housing 1 has a first mounting cavity 11. The five-stage reduction gear set 2 is disposed within the first mounting cavity 11 and meshes with a motor 3. The position detection component 4 is disposed within the first mounting cavity 11. The cover 5 is fixedly disposed on the top of the housing 1, and the cover 5 has a second mounting cavity 51. A control board is mounted within the second mounting cavity 51, and the control board is electrically connected to the motor 3 and the position detection component 4.

[0032] Specifically, the housing 1 has a first mounting cavity 11 for mounting a five-stage reduction gear set 2 and a position detection component 4. The five-stage reduction gear set 2 meshes with an unlocking component (not shown) to drive the unlocking component to rotate and complete the unlocking. The position detection component 4 is used to detect the position of the unlocking component, that is, to determine whether the unlocking component is in the unlocked position or has reset after unlocking. The cover 5 is located on the top of the housing 1. The edge of the first mounting cavity 11 is provided with a plurality of mutually spaced first fixing screw holes 8. The cover 5 is provided with a second mounting cavity 51, which is opposite to the first mounting cavity 11. The edge of the second mounting cavity 51 is provided with second fixing screw holes 9 opposite to the first fixing screw holes 8. Screws are threaded into the second fixing screw holes 9 and the first fixing screw holes 8 in sequence to fix the cover 5 to the top of the housing 1. The cover 5 can close the first mounting cavity 11. The control board (not shown) is fixedly installed in the second mounting cavity 51. The control board is electrically connected to the motor 3 and the position detection component 4 through wires (not shown). The control board can control the motor 3 to start, drive the five-stage reduction gear set 2 to rotate, and drive the unlocking component to move. The position detection component 4 can transmit the detection information to the control board.

[0033] By integrating the control board, five-stage reduction gear set 2, and position detection component 4, the internal spatial layout of the motor 3 lock body is optimized, improving space utilization and making the structure of the motor lock body more compact, meeting the market demand for lock body miniaturization. Simultaneously, the integrated design simplifies the production and assembly process; operators only need to position and install the overall component, eliminating the need for tedious assembly procedures for each small component, reducing assembly difficulty, improving production and assembly efficiency, and reducing component misalignment issues caused by assembly errors. Furthermore, the integrated design reduces the amount of fixing structures and connecting wires used, lowering component costs and consequently reducing the production and maintenance costs of the lock body. It also enhances the structural strength of the main lock body components, improving the lock body's impact and damage resistance, and extending its service life.

[0034] In one embodiment, the second mounting cavity 51 has a plurality of mounting boss screw holes 52, which are spaced apart along the edge of the second mounting cavity 51. The control board is fixed to the second mounting cavity 51 by the mounting boss screw holes 52 and screws.

[0035] Specifically, such as Figure 2 and Figure 5 As shown, the edge of the second mounting cavity 51 is provided with a plurality of mounting boss screw holes 52, and adjacent mounting boss screw holes 52 are spaced apart. The control plate has mounting holes corresponding to the mounting boss screw holes 52. Screws pass through the mounting holes and mounting boss screw holes 52 of the control plate in sequence to fix the control plate firmly in the second mounting cavity 51.

[0036] By setting multiple mounting boss screw holes 52, the control board is more securely installed and less prone to loosening, which improves the overall stability and reliability of the motor lock body five-stage reducer. At the same time, the screw installation method also facilitates subsequent maintenance and replacement, reducing maintenance costs.

[0037] In one embodiment, the cover 5 has a wire through hole 53, the second mounting cavity 51 is connected to the first mounting cavity 11 through the wire through hole 53, the wire through hole 53 is located on the top of the position detection component 4, and the wires are connected to the position detection component 4 and the control board through the wire through hole 53 respectively.

[0038] Specifically, such as Figure 2 and Figure 5 As shown, the wire through hole 53 is a rectangular hole. The wire through hole 53 is located at the bottom of the control board and at the top of the position detection component 4. After the wire is led out from the position detection component 4, it can be directly passed through the wire through hole 53 to achieve electrical connection with the control board without the need for additional winding or connection structure.

[0039] The through-hole 53 optimizes the wiring method inside the motor lock body, avoiding messy tangling of wires between the first mounting cavity 11 and the second mounting cavity 51, improving the neatness and reliability of the wiring, and reducing the risk of failure caused by wire tangling or poor contact; at the same time, the simple wiring method also facilitates subsequent maintenance and repair, reducing maintenance costs and time.

[0040] In one embodiment, the first mounting cavity 11 has a partition 12, which is used to divide the first mounting cavity 11 into a gear mounting position and a detection mounting position. The five-stage reduction gear set 2 is disposed in the gear mounting position, and the position detection component 4 is disposed in the detection mounting position.

[0041] Specifically, such as Figure 4 As shown, the first mounting cavity 11 is provided with a partition 12, which divides the first mounting cavity 11 into two independent spaces, left and right. The left space is the gear mounting position, and the right space is the detection mounting position. The five-stage reduction gear set 2 is installed in the gear mounting position, and the position detection component 4 is installed in the detection mounting position.

[0042] By setting a partition 12 to divide the first mounting cavity 11 into a gear mounting position and a detection mounting position, the five-stage reduction gear set 2 and the position detection component 4 have their own independent mounting space in the first mounting cavity 11, which avoids mutual interference between the two during operation and improves the stability and reliability of the motor lock body five-stage reducer operation.

[0043] In one embodiment, the position detection component 4 has at least one position detection switch 41, and the detection mounting position has a detection switch through hole 13 opposite to the position detection switch 41, through which the position detection switch 41 extends out of the detection mounting position.

[0044] Specifically, such as Figure 3 and Figure 4 As shown, the position detection component 4 includes two position detection switches 41. The two position detection switches 41 respectively acquire the position information of the unlocking component when it is fully unlocked or when it has reset after unlocking. When the unlocking component moves to a designated position, triggering either position detection switch 41 allows the position detection component 4 to determine whether the unlocking component is in the fully unlocked position or the reset position after unlocking. The detection mounting position is provided with detection switch through holes 13 corresponding to the position detection switches 41, allowing the position detection switches 41 to extend out of the detection mounting position and cooperate with the unlocking component.

[0045] By setting a position detection switch 41 and extending the position detection switch 41 through the detection switch through hole 13 to the detection mounting position, it can cooperate with the unlocking component to obtain the position information of the unlocked position and the position after unlocking, providing a reliable guarantee for the precise control and safe operation of the motor lock body.

[0046] In one embodiment, the five-stage reduction gear set 2 includes a first gear 21, a second gear 22, a third gear 23, a fourth gear 24, and a fifth gear 25 that mesh sequentially. The first gear 21 meshes with the motor 3, and the first gear 21, the third gear 23, and the fourth gear 24 are double gears for speed reduction.

[0047] Specifically, such as Figure 2 As shown, the larger diameter toothed portion of the first gear 21 meshes with the motor 3, the smaller diameter toothed portion of the first gear 21 meshes with the second gear 22, the second gear 22 meshes with the larger diameter toothed portion of the third gear 23, the smaller diameter toothed portion of the third gear 23 meshes with the larger diameter toothed portion of the fourth gear 24, and the smaller diameter toothed portion of the fourth gear 24 meshes with the fifth gear 25.

[0048] The design of the five-stage reduction gear set 2 makes the motor lock body more stable and reliable during operation, and can accurately control the movement speed and position of the unlocking component, thus improving the overall performance of the motor lock body.

[0049] In one embodiment, the first mounting cavity 11 has a first gear shaft 111, a second gear shaft 112, a third gear shaft 113, a fourth gear shaft 114, and a fifth gear shaft 115. The first gear 21, the second gear 22, the third gear 23, the fourth gear 24, and the fifth gear 25 are respectively sleeved on the first gear shaft 111, the second gear shaft 112, the third gear shaft 113, the fourth gear shaft 114, and the fifth gear shaft 115. The housing 1 has a first gear shaft hole 14, a second gear shaft hole 15, a third gear shaft hole 16, a fourth gear shaft hole 17, and a fifth gear shaft hole 18. One end of the first gear shaft 111, the second gear shaft 112, the third gear shaft 113, and the fourth gear shaft 114 is disposed in the first gear shaft hole 14, the second gear shaft hole 15, the third gear shaft hole 16, and the fourth gear shaft hole 17. The fifth gear shaft 115 passes through the fifth gear shaft hole 18 and is disposed in the first mounting cavity 11.

[0050] Specifically, such as Figures 2 to 4As shown, the housing 1 has a first gear shaft hole 14, a second gear shaft hole 15, a third gear shaft hole 16, a fourth gear shaft hole 17, and a fifth gear shaft hole 18. The lower ends of the first gear shaft 111, the second gear shaft 112, the third gear shaft 113, and the fourth gear shaft 114 are disposed in the first gear shaft hole 14, the second gear shaft hole 15, the third gear shaft hole 16, and the fourth gear shaft hole 17 and are fastened together. The first gear 21, the second gear 22, the third gear 23, and the fourth gear 24 are respectively sleeved on the first gear shaft 111, the second gear shaft 112, the third gear shaft 113, and the fourth gear shaft 114, and rotate about the first gear shaft 111, the second gear shaft 112, the third gear shaft 113, and the fourth gear shaft 114 as the center. The upper end of the fifth gear shaft 115 extends into the first mounting cavity 11 through the fifth gear shaft hole 18. The fifth gear 25 is sleeved on the end of the fifth gear shaft 115 that extends into the first mounting cavity 11. The fifth gear 25 is fastened to the fifth gear shaft 115. The lower end of the fifth gear shaft 115 located outside the housing 1 has a toothed portion. The fifth gear shaft 115 meshes with the unlocking component through this toothed portion. When the fifth gear 25 rotates, it drives the fifth gear shaft 115 to rotate, and the fifth gear shaft 115 drives the unlocking component to move.

[0051] By setting the first gear shaft 111, second gear shaft 112, third gear shaft 113, fourth gear shaft 114, and fifth gear shaft 115 within the first mounting cavity 11, and respectively mounting the first gear 21, second gear 22, third gear 23, fourth gear 24, and fifth gear 25 onto the gear shafts, stable installation and precise transmission of the five-stage reduction gear set 2 are achieved. Simultaneously, the first gear shaft hole 14, second gear shaft hole 15, third gear shaft hole 16, fourth gear shaft hole 17, and fifth gear shaft hole 18 provided on the housing 1 offer stable support points for the gear shafts, ensuring the stability and reliability of the gears during rotation.

[0052] In one embodiment, a retaining ring 6 for axially limiting the fifth gear 25 is provided on the fifth gear shaft 115.

[0053] Specifically, such as Figure 2 As shown, a retaining ring 6 is provided on the fifth gear shaft 115, and the retaining ring 6 is located on the side of the fifth gear 25 away from the fifth gear shaft hole 18. After the fifth gear 25 is installed on the fifth gear shaft 115, the retaining ring 6 is assembled onto the fifth gear shaft 115. The retaining ring 6 can restrict the axial movement of the fifth gear 25, preventing the fifth gear 25 from axially moving due to force during use, thereby ensuring the stability and reliability of the five-stage reduction gear set 2 transmission, avoiding problems such as poor gear meshing and transmission jamming caused by the axial movement of the fifth gear 25, and further improving the overall performance and service life of the motor lock body five-stage reducer.

[0054] In one embodiment, the cover 5 has a first gear shaft blind hole 54, a second gear shaft blind hole 55, a third gear shaft blind hole 56, a fourth gear shaft blind hole 57, and a cover fifth gear shaft hole 58. The other ends of the first gear shaft 111, the second gear shaft 112, the third gear shaft 113, and the fourth gear shaft 114 are respectively disposed in the first gear shaft blind hole 54, the second gear shaft blind hole 55, the third gear shaft blind hole 56, and the fourth gear shaft blind hole 57, and the other end of the fifth gear shaft 115 extends into the cover fifth gear shaft hole 58.

[0055] Specifically, such as Figure 5 and Figure 6 As shown, the first gear shaft blind hole 54, the second gear shaft blind hole 55, the third gear shaft blind hole 56, the fourth gear shaft blind hole 57, and the cover fifth gear shaft hole 58 are arranged opposite to the first gear shaft hole 14, the second gear shaft hole 15, the third gear shaft hole 16, the fourth gear shaft hole 17, and the fifth gear shaft hole 18. The upper ends of the first gear shaft 111, the second gear shaft 112, the third gear shaft 113, and the fourth gear shaft 114 are respectively located in the first gear shaft blind hole 54, the second gear shaft blind hole 55, the third gear shaft blind hole 56, and the fourth gear shaft blind hole 57. The first gear shaft blind hole 54 and the first gear shaft hole 14 cooperate to fix the first gear shaft 111. The second gear shaft blind hole 55 and the second gear shaft hole 15 cooperate to fix the second gear shaft 112. The third gear shaft blind hole 56 and the third gear shaft hole 16 cooperate to fix the third gear shaft 113. The fourth gear shaft blind hole 57 and the fourth gear shaft hole 17 cooperate to fix the fourth gear shaft 114. The upper end of the fifth gear shaft 115 is rotatably disposed in the fifth gear shaft hole 58 of the cover.

[0056] By setting corresponding gear shaft holes and blind holes on the cover 5 to those on the housing 1, dual fixing of each stage of gear shafts is achieved, further enhancing the stability and reliability of the gear shafts, reducing wobbling and offset during rotation, and ensuring precise transmission and stable operation of the five-stage reduction gear set 2. At the same time, it improves the overall structural strength of the motor lock body five-stage reducer, enabling it to better withstand external impacts and vibrations, and extending its service life.

[0057] In one embodiment, the housing 1 has a motor mounting plate 19, the motor 3 is disposed in a pair of motor housings 7, the pair of motor housings 7 are fixedly connected to the motor mounting plate 19, the motor mounting plate 19 has an output shaft through hole 191, the output shaft of the motor 3 extends into the first mounting cavity 11 through the output shaft through hole 191, the output shaft of the motor 3 is fixedly connected to a bevel gear 31, and the bevel gear 31 meshes with a five-stage reduction gear set 2.

[0058] Specifically, such as Figure 2As shown, the housing 1 has a motor mounting position, and a motor mounting plate 19 is disposed within the motor mounting position. The motor mounting plate 19 has an output shaft through hole 191. The motor housing 7 and the motor mounting plate 19 are fixed with screws. A pair of motor housings 7 are joined together to form a cavity for accommodating the motor 3. The motor 3 is disposed in the cavity, and the output shaft of the motor 3 extends out of the cavity, passes through the output shaft through hole 191, and extends into the first mounting cavity 11. The output shaft of the motor 3 is provided with a bevel gear 31. The larger diameter tooth of the first gear 21 is a bevel tooth. The bevel gear 31 meshes with the bevel tooth, thereby driving the first gear 21 to rotate.

[0059] By setting up the motor mounting plate 19 and the motor housing 7, the motor 3 is securely installed and protected, preventing it from being affected by external impacts and vibrations during operation, thus improving the service life and operational stability of the motor 3. At the same time, the fixed connection between the motor housing 7 and the motor mounting plate 19 facilitates the installation and disassembly of the motor 3, reducing maintenance costs and time.
