Description

Technical Field

[0001] The utility model relates to the technical field of automatic locks, in particular to a structure of upper and lower deadbolts of an automatic lock body. Background Art

[0002] In the design of door locks, in order to enhance the structural strength and protection of the door, upper and lower deadbolts are usually provided on the door lock. These deadbolts can engage with corresponding components on the door frame in the locked state, so as to achieve a more secure locking effect. In order to further improve the safety performance, these deadbolts are also equipped with deadlocks to ensure that the door cannot be easily opened without using a key or the correct password.

[0003] In the existing lock designs, independent transmission mechanisms are usually adopted to control the movement of the upper and lower deadbolts. These transmission parts need to move towards or away from each other to lock and unlock the deadbolts. In order to synchronously drive these two transmission parts, conventional locks usually need to set up complex transmission structures, such as using a turntable or a gear system. This complex transmission structure not only increases the overall volume of the lock, making the lock appear bulky, but also brings great difficulties in the assembly and maintenance processes. The complex mechanical structure is prone to wear and failure, increasing the maintenance cost and difficulty, and at the same time affecting the reliability and service life of the lock.

[0004] In addition, the complex transmission structure also faces many challenges in the design and manufacturing processes. Due to the need for precise machining and assembly processes, the manufacturing cost is relatively high. This brings no small obstacle to the large-scale production and market promotion of locks. Especially in the modern design trend of pursuing lightness, simplicity and efficiency, the traditional complex transmission structure is increasingly difficult to meet the market demand.

[0005] Therefore, it is necessary to further improve and perfect the existing technology to overcome these deficiencies, and the present utility model is made based on this situation. Summary of the Utility Model

[0006] The purpose of the utility model is to overcome the deficiencies of the existing technology and provide an automatic lock body upper and lower deadbolt structure with a simple structure, which is more compact, easy to assemble and maintain.

[0007] The utility model is realized through the following technical solutions:

[0008] To solve the above technical problems, the present utility model provides an automatic lock body upper and lower locking hooks structure, which includes a lock housing. A upper and lower locking hook transmission member capable of sliding in the up and down direction is slidably connected in the lock housing. The upper and lower ends of the upper and lower locking hook transmission member are respectively detachably connected with an upper locking hook and a lower locking hook. A driving wheel is rotatably connected in the lock housing. An electric driving assembly and a manual driving assembly are further provided in the lock housing. Both the electric driving assembly and the manual driving assembly are in transmission connection with the driving wheel and can drive the driving wheel to rotate. A first eccentric post deviating from the rotation center is provided on the driving wheel. A first guiding hole for inserting the first eccentric post is provided on the upper and lower locking hook transmission member, so that when the driving wheel rotates, it drives the upper and lower locking hook transmission member to move up and down.

[0009] To further solve the technical problems to be solved by the present utility model, in the automatic lock body upper and lower locking hooks structure provided by the present utility model, the first guiding hole is a T-shaped hole and includes a transverse portion and a longitudinal portion that are connected. The transverse portion extends in the inner and outer direction, and the longitudinal portion extends in the up and down direction.

[0010] To further solve the technical problems to be solved by the present utility model, in the automatic lock body upper and lower locking hooks structure provided by the present utility model, a strip-shaped hole is provided on the upper and lower locking hook transmission member along the up and down direction. A guiding post inserted into the corresponding strip-shaped hole and sliding up and down therein is provided on the lock housing. A rotating sleeve is sleeved on the guiding post.

[0011] To further solve the technical problems to be solved by the present utility model, in the automatic lock body upper and lower locking hooks structure provided by the present utility model, both the upper locking hook and the lower locking hook are connected with upper and lower locking devices, and when each upper and lower locking device is unlocked and locked, the moving directions of the upper locking hook and the lower locking hook are the same.

[0012] To further solve the technical problems to be solved by the present utility model, in the automatic lock body upper and lower locking hooks structure provided by the present utility model, a main lock tongue is slidably connected in the lock housing along the inner and outer direction. A second eccentric post deviating from the rotation center is provided on the driving wheel. A second guiding hole for inserting the second eccentric post is provided on the main lock tongue, so that when the driving wheel rotates, it drives the main lock tongue to move in and out.

[0013] To further solve the technical problems to be solved by the present utility model, in the automatic lock body upper and lower locking hooks structure provided by the present utility model, a circuit board is provided in the lock housing. A Hall sensor assembly is provided between the circuit board and the main lock tongue. The circuit board is electrically connected with the electric driving assembly.

[0014] Compared with the prior art, the present utility model has the following advantages:

[0015] 1. The utility model adopts a single top and bottom hook transmission member, which drives the top and bottom hook transmission member to move up and down through a driving wheel, thereby driving the upper top and bottom hook and the lower top and bottom hook to move in the same direction. This design greatly simplifies the lock body structure because there is no longer a need to control the upper top and bottom hook and the lower top and bottom hook separately, reducing the number and complexity of transmission members. The structure is simpler and more compact, not only reducing the manufacturing cost and assembly difficulty, but also improving the accuracy and reliability of control.

[0016] 2. The first guiding hole is a T-shaped hole and includes a connected transverse part and a longitudinal part. Such a design not only ensures the smooth operation of the transmission member, but also effectively reduces the wear between mechanical components. Because compared with the traditional sliding structure, the T-shaped hole can better disperse the friction force, reduce the local stress condition, and thus extend the service life of mechanical components.

[0017] 3. To achieve precise detection and control of the position of the main lock tongue, a Hall sensor assembly is provided between the circuit board and the main lock tongue. Through the feedback of the Hall sensor assembly, the circuit board can accurately know whether the main lock tongue is in the locked state or the unlocked state. This real-time monitoring not only improves the safety performance of the lock body, but also can issue an alarm or take corresponding safety measures in a timely manner when an abnormal situation occurs. In addition, the electrical connection between the circuit board and the electric drive assembly enables the lock body to automatically perform locking or unlocking operations according to the detected position change of the main lock tongue.

[0024] Figure 6 is Figure 5 a partial enlarged view at B in Specific Embodiments

[0025] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] As Figures 1 to 6 shown, an automatic lock body top and bottom hook structure includes a lock shell 1. A top and bottom hook transmission member 2 that can slide in the up and down direction is slidably connected in the lock shell 1. Upper and lower top and bottom hooks (not shown in the figure) are detachably connected to the upper and lower ends of the top and bottom hook transmission member 2 respectively. When in the locked state, these top and bottom hooks can ensure that both the upper and lower parts of the door are protected, enhancing the overall security. Of course, the upper and lower top and bottom hooks are both connected to a top and bottom lock (not shown in the figure). When unlocking and locking, the movement directions of the upper and lower top and bottom hooks are the same, that is, they move in the same direction.

[0027] A driving wheel 3 is rotatably connected in the lock shell 1. An electric driving component 4 and a manual driving component 5 are further provided in the lock shell 1. Both the electric driving component 4 and the manual driving component 5 are in transmission connection with the driving wheel 3 and can both drive the driving wheel 3 to rotate. The electric driving component 4 usually includes a motor, and the manual driving component 5 usually includes a lock core component and a handle component. This design not only provides automated convenience but also enables manual operation in the case of power failure or emergency.

[0028] A first eccentric column 31 deviating from the rotation center is provided on the driving wheel 3. A first guiding hole 21 for inserting the first eccentric column 31 is provided on the top and bottom hook transmission member 2. When the driving wheel 3 rotates, the first eccentric column 31 drives the top and bottom hook transmission member 2 to translate up and down through the first guiding hole 21. In this way, the rotational motion of the driving wheel 3 is converted into the linear motion of the top and bottom hook transmission member 2.

[0029] The present utility model adopts a single top and bottom hook transmission member 2. The driving wheel 3 drives the top and bottom hook transmission member 2 to translate up and down, thereby driving the upper and lower top and bottom hooks to move in the same direction. This design greatly simplifies the lock body structure because there is no longer a need to control the upper and lower top and bottom hooks separately, reducing the number and complexity of transmission members. The structure is simpler and more compact, not only reducing the manufacturing cost and assembly difficulty but also improving the control accuracy and reliability.

[0030] More specifically, the first guiding hole 21 is a T-shaped hole and includes a transverse portion 211 and a longitudinal portion 212 that are connected and communicate with each other. The transverse portion 211 extends in the inner-outer direction, and the longitudinal portion 212 extends in the up-down direction. The eccentric column 31 can drive the sky-earth hook transmission member 2 to perform stable up-down translation movement when the driving wheel 3 rotates. Such a design not only ensures the smooth operation of the transmission member 2 but also effectively reduces the wear between mechanical components. Because compared with the traditional sliding structure, the T-shaped hole can better disperse the frictional force, reduce the local stress condition, and thus extend the service life of mechanical components.

[0031] More specifically, a strip-shaped hole 22 extending in the up-down direction is provided on the sky-earth hook transmission member 2. This strip-shaped hole is designed to provide precise guidance and limitation for the transmission member in the up-down direction. At the same time, a guiding column 11 is provided on the lock housing 1. The guiding column 11 is precisely inserted into the corresponding strip-shaped hole 22 and slides in it in the up-down direction. In order to further improve the smoothness of the sliding and reduce friction, a rotating sleeve 12 is sleeved on the guiding column 11. The design of the rotating sleeve 12 provides a flexible rotating structure for the guiding column, which not only enables the guiding column to slide more smoothly up and down in the strip-shaped hole 22 but also effectively reduces the wear caused by direct friction.

[0032] A main lock tongue 6 is slidably connected in the lock housing 1 in the inner-outer direction. In order to drive the movement of the main lock tongue 6, a second eccentric column 32 offset from the rotation center is provided on the driving wheel 3, and a second guiding hole 61 for the second eccentric column 32 to be inserted is provided on the main lock tongue 6. This design enables the second eccentric column 32 to drive the main lock tongue 6 to perform smooth inner-outer translation through the second guiding hole 61 when the driving wheel 3 rotates.

[0033] More specifically, a circuit board 13 is provided in the lock housing 1 for the control and management of the overall circuit. In order to achieve precise detection and control of the position of the main lock tongue 6, a Hall sensor assembly 14 is provided between the circuit board 13 and the main lock tongue 6. The purpose of this assembly is to sense the position change of the main lock tongue 6 and feedback the signal to the circuit board 13 in real time for corresponding control operations.

[0034] The circuit board 13 is electrically connected to the electric driving assembly 4, ensuring that the driving assembly can perform precise action control according to the instructions of the circuit board. This connection method enables the lock body to realize electric operation, improving the intelligent level and use convenience.

[0035] As Figure 6As shown, the Hall sensor assembly 14 generally includes an electromagnet disposed on the main lock tongue 6 and a Hall sensing device disposed on the circuit board 13. Specifically, when the main lock tongue 6 slides in the lock housing 1, the electromagnet moves accordingly, generating a corresponding change in the magnetic field. The Hall sensing device can sense this change in the magnetic field and convert it into an electrical signal and transmit it to the circuit board 13. These signals can be used to determine the position of the main lock tongue 6, thereby realizing real-time monitoring of its movement state.

[0036] The circuit board 13 can accurately know whether the main lock tongue 6 is in a locked state or an unlocked state through the feedback of the Hall sensor assembly 14. This real-time monitoring can not only improve the safety performance of the lock body, but also can promptly issue an alarm or take corresponding safety measures when an abnormal situation occurs.

[0037] In addition, the electrical connection between the circuit board 13 and the electric drive assembly 4 enables the lock body to automatically lock or unlock according to the detected position change of the main lock tongue 6. For example, when it is detected that the main lock tongue 6 is in the unlocked position, the circuit board 13 can instruct the electric drive assembly 4 to start and push the main lock tongue back to the locked position to ensure the safety of the lock body.

[0038] The advantage of this design is that it not only improves the intelligence and automation level of the lock body, but also significantly enhances its safety and reliability.

[0039] Of course, an oblique lock tongue is slidably connected in the lock housing 1 along the inward and outward directions, and the electric drive assembly 4 and the manual drive assembly 5 are both transmission-connected to the oblique lock tongue and can drive the oblique lock tongue to extend and retract inward and outward.
