Description

Technical Field

[0001] This utility model relates to the field of door lock technology, and in particular to a fully automatic cabinet door drive system. Background Technology

[0002] In the field of door lock technology, the safety, reliability, and ease of operation of fully automatic cabinet door drive systems are of paramount importance. However, existing cabinet door drive devices generally suffer from the following technical shortcomings:

[0003] Traditional cabinet door drive systems often employ a single locking mode, relying either on electronic passwords or only equipped with mechanical locks. When the electronic system loses power, it may fail to unlock. Mechanical locks alone pose insufficient security risks and are easily cracked. The lack of a dual-security mechanism limits the application scenarios.

[0004] In terms of structural design, the locking limit post of some products is fixed by welding the door panel, which makes it difficult to guarantee the positional accuracy. In addition, the resistance of the transmission components is relatively large, and jamming is prone to occur during operation. Traditional gearboxes (such as worm gear structures) have the problem of stroke lock-up, which results in high resistance and inflexible operation when mechanical key is driven, affecting the user experience.

[0005] The lack of anti-misoperation design is another prominent problem. The existing locking structure is prone to accidental sliding of the locking pin due to external impact or component wear, which may cause the cabinet door to be opened or locked accidentally, posing a safety hazard.

[0006] In addition, most products still require manual twisting of the handle to complete the opening, closing and locking actions, lacking automatic detection and response functions. This is especially inconvenient to operate in scenarios such as holding objects with both hands, resulting in a poor user experience. At the same time, the insufficient precision of the guide limit structure leads to poor stability of the locking device, and long-term use can easily cause problems such as accelerated wear of components. Utility Model Content

[0007] The main purpose of this utility model is to provide a fully automatic cabinet door drive system, which can effectively solve the problems in the background art.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] The fully automatic cabinet door drive assembly includes a metal panel. A controller is located on the right side of the front end of the metal panel. A mechanical lock is located on the left side of the front end of the metal panel. A locking device is installed on the left side of the rear end of the metal panel. A protective shell is located at the rear end of the metal panel. A magnetic induction controller is located on the right side of the protective shell. The locking device is located inside the protective shell. A magnetic induction probe is installed on the top of the protective shell.

[0010] Preferably, the locking device includes a driver and a travel plate. The driver is fixed to the rear end of the metal panel. An L-shaped locking plate is sleeved on the tail of the mechanical lock. A driving plate is sleeved on the output end of the driver. A connecting piece is fixed to the left end of the travel plate. Several locking pins are installed on the left end of the connecting piece. All of the locking pins extend through the metal panel to the outside.

[0011] Preferably, the upper right side of the travel piece has two limiting grooves, and an L-shaped drive groove is provided between the two limiting grooves on the upper right side of the travel piece.

[0012] Preferably, two triangular protrusions are installed on the top of the drive plate, and a limit post is installed at the bottom rear end of the drive plate.

[0013] Preferably, two limiting posts that match the limiting groove are installed in the middle of the rear end of the driver.

[0014] Preferably, the vertical portion of the L-shaped drive groove is inclined to the right, and the dimensions of the top and bottom of the vertical portion of the L-shaped drive groove are both larger than the dimensions of the middle portion.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model has a dual locking / unlocking method with electronic password and mechanical key. The two do not interfere with each other and form a double insurance. Even if the controller loses power, it can still be operated by mechanical key to ensure that the cabinet door can be locked and opened normally under various circumstances, thus improving security and reliability.

[0017] 2. The driver of the lock in this utility model adopts a combination of a motor and a crown gear transmission. The limit post is installed using the screw hole of the transmission, which eliminates the need for welding on the door panel. The position is accurate and the movement resistance is small and smoother. The crown gear transmission has both damping resistance and arbitrary forward and reverse functions, so that the travel plate can stop at any stroke, avoiding the stroke lock-up like a worm gear transmission, and making the mechanical key drive smoother.

[0018] 3. In this utility model, the magnetic induction controller and magnetic induction probe can automatically detect the position and drive the driver to lock when the door is closed, without the need to manually turn the handle, truly realizing a fully automatic function. The door will not lock when it is open, making it convenient to use and improving the user experience. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1-6 As shown, the fully automatic cabinet door drive assembly includes a metal panel 1, a controller 2 on the right side of the front end of the metal panel 1, a mechanical lock 3 on the left side of the front end of the metal panel 1, a locking device 5 on the left side of the rear end of the metal panel 1, a protective shell 4 at the rear end of the metal panel 1, a magnetic induction controller 6 on the right side of the protective shell 4, the locking device 5 located inside the protective shell 4, and a magnetic induction probe 7 installed on the top of the protective shell 4.

[0028] During implementation, a battery needs to be implanted inside the protective shell 4 to power the controller 2.

[0029] There are two locking / unlocking methods in this case:

[0030] 1. By operating controller 2 and entering the correct password, controller 2 sends a command to lock 5 and activates lock 5. After lock 5 extends, it limits the distance between the door frame and the door, thereby completing the locking / unlocking process.

[0031] 2. Using a mechanical key, insert the mechanical key into the mechanical lock 3 and turn the key to drive the locking device 5, which can also complete the locking / unlocking process.

[0032] Furthermore, in this case, locking / unlocking with the key and locking / unlocking via controller 2 do not interfere with each other.

[0033] To accomplish the above objectives, see [reference] Figure 3 , Figure 4 , Figure 5 and Figure 6 In this case, the locking device 5 includes a driver 51 and a travel plate 54. The driver 51 is fixed to the rear end of the metal panel 1. The tail of the mechanical lock 3 is fitted with an L-shaped locking plate 53. The output end of the driver 51 is fitted with a driving plate 55. The left end of the travel plate 54 is fixed with a connecting plate 57. Several locking pins 56 are installed on the left end of the connecting plate 57. The locking pins 56 all extend through the metal panel 1 to the outside.

[0034] The aforementioned driver 51 consists of a motor and a crown gear transmission. Two limit posts 511 are installed in the screw posts of the housing of the crown gear transmission to guide the travel plate 54 during movement.

[0035] The limit post 511 is installed using the screw holes of the crown gear transmission, eliminating the need to weld the limit post 511 to the door panel. This results in more precise positioning, more flexible movement, reduced resistance, and a smoother operation.

[0036] In this case, the transmission characteristics of the crown gear transmission are utilized. It has both damping resistance function and the ability to rotate freely in both directions, allowing the travel plate 54 to stop at any point in the travel. Therefore, it will not lock the travel like a lever transmission, preventing the key from turning the drive plate 55.

[0037] Two limiting grooves 541 are provided on the upper right side of the travel plate 54, and an L-shaped drive groove 542 is provided on the upper right side of the travel plate 54 between the two limiting grooves 541.

[0038] In the unlocked state, the two triangular protrusions 551 are both located on the right side of the L-shaped lock plate 53, the second limiting post 543 is located at the bottom of the vertical part of the L-shaped drive groove 542, and the L-shaped lock plate 53 is above the mechanical lock 3.

[0039] When locking, after the driver 51 is driven by the controller 2, the drive plate 55 can be driven to rotate counterclockwise, so that the limit post 543 slides upward in the vertical part of the L-shaped drive groove 542. The limit post 543 pushes the travel piece 54 to the left and pushes out the lock post 56 through the connecting piece 57, completing the locking action. At this time, both triangular protrusions 551 are facing upward. The mechanical key is used to turn the mechanical lock 3, which drives the L-shaped lock piece 53 to rotate and move the L-shaped lock piece 53 between the two limit posts 511, completing the mechanical key locking and finally completing the double-layer locking.

[0040] Two triangular protrusions 551 are installed on the top of the drive board 55, and a limit post 543 is installed at the bottom rear end of the drive board 55.

[0041] After the two limiting posts 511 are installed in the inner cavity of the limiting groove 541, they can be used to guide the travel piece 54 when it moves.

[0042] Two limit posts 511 that match the limit slots 541 are installed at the middle of the rear end of the driver 51.

[0043] The vertical part of the L-shaped drive groove 542 is tilted to the right, and the top and bottom dimensions of the vertical part of the L-shaped drive groove 542 are larger than the middle dimension, to prevent the lock pin 56 from accidentally unlocking or locking after sliding back into the inner cavity of the protective shell 4 without a mechanical key.

[0044] When the controller 12 has no power supply, since the L-shaped locking piece 53 is located between the two triangular protrusions 551 after locking, according to the transmission characteristics of the crown gear transmission, the triangular protrusions 551 can be turned clockwise by using a mechanical key to complete the unlocking.

[0045] Secondly, this case also features a contactless door closing and automatic locking function:

[0046] With the magnetic induction function of the magnetic induction controller 6, when the magnetic induction probe 7 detects the closed position, it locks the electric drive 51. When the door is open, it will never lock, and there is no need to turn the handle to open or close the door, truly realizing a fully automatic function and providing a better user experience.

[0047] 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.
