Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic lock technology, and in particular to an electronic lock core interlocking power structure. Background Technology
[0002] Please refer to the instruction manual. Figures 1-2 The common electronic lock interlocking structure includes a lock housing 101, a control main board 102, a mounting bracket 103, a first square iron frame 104, a second square iron frame 105, a square iron cylinder 106, a bolt 107, and a motor 108. The mounting bracket 103 is mounted on the lock housing 101. The first square iron frame 104 is rotatably connected to the mounting bracket 103, and the second square iron frame 105 is rotatably connected to the first square iron frame 104. The bolt 107 is slidably mounted on the first square iron frame 104 by a spring. The motor 108 changes its output direction through gear transmission to push the arc-shaped block to press the bolt 107. The second square iron frame 105 has a socket 109. The bolt 107 is inserted into the socket 109, so that the first square iron frame 104 and the second square iron frame 105 are interlocked. This allows the rotation of the external handle to transmit output force through the first square iron frame 104 and the second square iron frame 105 to drive the internal handle to rotate and open the door. This traditional interlocking structure, to a certain extent, meets the basic functional requirements of electronic locks, realizes the opening and closing control of the door lock, and also shows a certain degree of reliability in terms of structural stability, effectively maintaining the locked state of the door lock.
[0003] However, existing electronic lock interlocking structures still have some problems. The main problem is that the motor output shaft needs to be driven by gears to output its rotational force as the ejection action. Due to transmission losses, the motor often needs to rotate multiple times to achieve the ejection action. Therefore, the motor's ejection power consumption accounts for 30% of the total energy loss of the electronic lock, resulting in high overall energy consumption. Moreover, if the gear ratio is improved to alleviate this situation, the motor load will increase, further increasing energy consumption. This makes it difficult for the electronic lock to achieve higher energy efficiency standards, which not only adversely affects the long-term economic efficiency of the electronic lock but also limits its technological development and application expansion in the field of energy conservation. Therefore, there is an urgent need to propose a new interlocking structure to solve the above problems. Utility Model Content
[0004] In view of this, the embodiments of this utility model provide an electronic lock core interlocking power structure to reduce the technical problem of long motor output path and large transmission loss.
[0005] An embodiment of this utility model provides an electronic lock cylinder interlocking power structure, comprising: shell; A drive structure is disposed within the housing, the drive structure including a motor and a gear, the output end of the motor being connected to the gear shaft; A first spindle and a second spindle are provided. The first spindle is movably disposed within the housing and is movably connected to the outer handle. The second spindle is connected to the inner handle. The first spindle includes a first shaft tube and a gear ring. The gear meshes with the gear ring. The motor drives the gear to rotate. Under the meshing transmission of the gear and the gear ring, the first spindle extends out and connects with the second spindle, so that the outer handle can drive the inner handle to rotate.
[0006] Furthermore, a guide structure is provided inside the outer casing. The guide structure includes a guide tube and two open plates. The outer wall of the guide tube is open, and the two open plates are connected to the openings of the guide tube. The gear is rotatably mounted on the two open plates.
[0007] Furthermore, a first square hole is provided on the end of the first shaft tube away from the second mandrel, and square iron is provided at the ends of both the outer handle and the inner handle, and the first square hole and the square iron are inserted into each other.
[0008] Furthermore, the second mandrel includes a second shaft tube, and a second square hole is provided on the end of the second shaft tube away from the first shaft tube. The second square hole is inserted into the square iron on the inner handle.
[0009] Furthermore, both the first shaft tube and the second shaft tube are provided with bevel teeth at their ends, and the two bevel teeth mesh with each other.
[0010] Furthermore, one of the bevel teeth has a countersunk hole at its center, and the other bevel tooth has a guide pin at its center, the guide pin being movably connected to the countersunk hole.
[0011] Furthermore, the housing includes a lock frame and a control panel, both the outer handle and the inner handle are rotatably disposed outside the lock frame, and the control panel is built into the lock frame and electrically connected to the motor.
[0012] Furthermore, a mounting platform is provided on the inner wall of the lock frame, and the motor is mounted on the mounting platform.
[0013] Furthermore, friction pressure plates are provided at the ends of both the first shaft tube and the second shaft tube. The two friction pressure plates abut against each other, so that the outer handle can drive the inner handle to rotate through frictional transmission.
[0014] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows: The electronic lock cylinder interlocking power structure of this utility model, through the meshing of the gear and the gear ring driven by the motor, drives the first spindle to extend and connect with the second spindle, realizing that the outer handle drives the inner handle to rotate and open the door. Compared with the traditional structure of two square iron parts connected and the motor pushes the top pin for interlocking, this transmission method reduces the number of rotations of the motor output shaft, thereby effectively reducing energy consumption, reducing motor output loss, and improving the energy efficiency of the electronic lock. Secondly, the guide structure set inside the outer shell, including the guide tube and the opening plate, provides stable installation and rotation support for the gear, ensuring the precise meshing of the gear and the gear ring, improving the stability and reliability of the transmission, reducing the risk of mechanical failure caused by transmission errors, providing users with a more convenient and stable user experience, and has high market application value and promotion prospects.

[0022] It should be further noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] Please refer to Figures 3 to 5 The present invention provides an electronic lock cylinder interlocking power structure, including a housing, a drive structure, a first spindle and a second spindle, wherein the housing includes a lock frame 1 and a control panel 2.
[0024] The lock frame 1 serves as the main support frame of the entire electronic lock cylinder interlocking power structure. It has good sturdiness and stability, and can effectively protect the internal components and prevent external forces from damaging them. The control panel 2 is built into the front end of the lock frame 1 and is connected to the motor 11 through multiple wires.
[0025] The control panel 2 integrates various electronic components, including but not limited to a microprocessor, memory, and communication module. The microprocessor runs preset control programs to precisely control the motor 11, such as controlling its forward and reverse rotation, start / stop, and speed adjustment. The memory stores user fingerprint information, password information, and unlocking records for comparison and retrieval during user authentication. The communication module enables wireless communication with external devices such as mobile apps and smart home systems, facilitating remote control and information transmission.
[0026] Please refer to Figure 3 In this embodiment, the drive structure is disposed inside the housing, and the drive structure includes a motor 11 and a gear 9, with the output end of the motor 11 connected to the shaft of the gear 9.
[0027] The motor 11 is mounted on the mounting platform 10 on the inner wall of the lock frame 1. The mounting platform 10 is fixed to the inner wall of the lock frame 1 with bolts, providing a stable mounting base for the motor 11 and lifting the motor 11 to a suitable height position.
[0028] The output shaft of motor 11 is precision machined and connected to the shaft of gear 9 by a flat key, ensuring that power can be transmitted smoothly and accurately to gear 9 during motor operation.
[0029] Furthermore, a keyway matching the output shaft of motor 11 is machined at the axial position of gear 9, and it is connected to the output shaft of motor 11 via a flat key, thereby achieving synchronous rotation. The module and number of teeth of gear 9 are precisely calculated to ensure that sufficient torque is generated to drive the extension action of the first spindle when meshing with gear ring 8, while taking into account the smoothness and reliability of transmission.
[0030] Please refer to Figure 5 In this embodiment, the gear ring 8 has multiple equally spaced teeth arranged on the outer circumference of the cylinder of the first shaft tube 6, meshing with the gear 9. Thus, when the first shaft tube 6 rotates, it can still maintain meshing with the gear 9. The other end of the first shaft tube 6 is machined with a first square hole 7. The size and shape of the first square hole 7 are adapted to the square iron 3 at the end of the outer handle. The two are inserted together using a clearance fit, ensuring that the rotational action of the outer handle can be smoothly transmitted to the first shaft tube 6 through the fit between the square iron 3 and the first square hole 7, thereby driving the first spindle to perform corresponding movements.
[0031] It should be noted that the tooth profile of the gear ring 8 is precision machined to match the tooth profile of the gear 9, enabling high-precision meshing transmission. When the motor 11 drives the gear 9 to rotate, the meshing force between the gear 9 and the gear ring 8 causes the first shaft tube 6 to drive the first spindle to extend smoothly outward along the guide structure until it connects with the second spindle.
[0032] In addition, one end of the second shaft tube 13 is fixedly connected to the inner handle, and the other end is machined with a second square hole 14. The second square hole 14 is connected to the square iron 3 at the end of the inner handle by a clearance fit insertion method, so that the rotation of the inner handle can be transmitted to the second shaft tube 13 through the cooperation between the square iron 3 and the second square hole 14, thereby driving the second spindle to rotate.
[0033] In order to enable transmission after the first shaft tube 6 and the second shaft tube 13 come into contact, in an optional embodiment, the end of the second shaft tube 13 is also provided with bevel teeth 12. The module and number of teeth of the bevel teeth 12 match the bevel teeth 12 at the end of the first shaft tube 6. The two mesh with each other to realize the transmission of power in the vertical direction, further improving the transmission efficiency and flexibility of the lock cylinder.
[0034] To improve the coaxiality of the first spindle tube 6 and the second spindle tube 13, a countersunk hole 15 is machined at the center of one bevel tooth 12, and a guide pin 16 is provided at the center of the other bevel tooth 12. When the first spindle and the second spindle are connected, the guide pin 16 is inserted into the countersunk hole 15, allowing for a certain degree of relative movement between them, ensuring engagement accuracy, and improving the service life and reliability of the lock cylinder.
[0035] In another optional embodiment, friction plates are installed at the ends of both the first shaft tube 6 and the second shaft tube 13. The friction plates are made of a composite material with a high coefficient of friction, and multiple annular grooves are machined on the outer circumferential surface of the friction plates to increase the friction area and friction force. The end faces of the two friction plates abut against each other to form a tight friction pair.
[0036] When the outer handle rotates, the friction between the friction plates causes the inner handle to rotate as well.
[0037] To support gear 9 and provide guidance for the movement of the first shaft tube 6, a guide structure is provided inside the housing, including a guide tube 4 and two open plates 5. An opening extending axially is machined on the outer wall of the guide tube 4, and the inner diameter of the guide tube 4 is adapted to the outer diameter of the first and second mandrels, providing guidance for the movement of the mandrels and ensuring that the mandrels always maintain linear movement during extension and retraction, avoiding deviation or jamming.
[0038] Furthermore, two open plates 5 are respectively connected to the openings of the guide tube 4, forming a stable support frame. The open plates 5 are machined with bearing holes for mounting the gear 9. The size of the bearing holes matches the journal of the gear 9. By installing high-precision bearings, it is ensured that the gear 9 can rotate freely on the open plates 5, while ensuring the meshing accuracy between the gear 9 and the gear ring 8.
[0039] Please refer to Figure 4In this embodiment, the square iron 3 at the ends of the outer handle and the inner handle has a square cross-section, and its size matches the size of the first square hole 7 and the second square hole 14 to ensure the tightness and reliability of the insertion.
[0040] In addition, the first square hole 7 and the second square hole 14 are respectively machined at the ends of the first shaft tube 6 and the second shaft tube 13. The shape and size of the holes are precisely machined to match the shape of the square iron 3.
[0041] It should be noted that a magnetic switch is also installed inside the lock frame 1 on the control board 2. The magnetic switch is controlled by an electrical connection to a wake-up switch. There are two types of wake-up switches: one is located on the touch screen panel, and the other is located at the fingerprint recognition area. Both are controlled by pressing.
[0042] In this way, by pressing the touch screen panel or using fingerprint recognition, the magnetic switch can be controlled by the wake-up switch to connect the motherboard 2 and the battery compartment. That is, pressing activates the electronic lock and turns on its power. When not in use, the battery compartment is in a power-off state, the electronic lock circuit is disconnected, and the power consumption is prevented from increasing due to standby.
[0043] More specifically, the lock frame 1 is equipped with a battery compartment and a capacitor battery as two input sources. The battery compartment and the capacitor battery are unidirectionally connected through a diode. The electronic lock can also use an external handle to connect a generator to generate electricity, and the electrical energy is stored in the capacitor battery to control the main board 2 to drive the motor 11.
[0044] Additionally, it is worth noting that there is another pathway between the battery compartment and the motherboard to facilitate switching control states. One method is a connection via a magnetic switch, and the other is a direct connection. Therefore, users can flexibly choose between conventional use and standby-free energy-saving mode.
[0045] In this document, the directional terms such as front, back, top, and bottom are defined based on the position of the components in the accompanying drawings and their relative positions to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.
[0046] Where there is no conflict, the above embodiments and features described herein can be combined with each other.
[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
