[0058] Please refer to Figure 1, this embodiment provides a contactless automatic switch compartment door device, including: a lock body module, a door opener, and an induction control module; the lock body module includes an automatic unlocking and locking component and a manual unlocking and locking component, and both the automatic unlocking and locking component and the manual unlocking and locking component are adapted to drive the lock bolt 7 to complete the unlocking and locking actions; the automatic unlocking and locking component includes a first driving component and a first transmission component; the control end of the first driving component is connected to the induction control module, the driving end is connected to the first transmission component, the first transmission component is connected to the lock bolt 7, and the first transmission component is adapted to convert the driving movement of the first driving component into the horizontal movement of the lock bolt 7; the manual unlocking and locking component includes a mechanical knob 3 and a second transmission component; one side of the mechanical knob 3 is a knob part, and the other side is provided with a connecting column 4. The second transmission component is provided with a connecting hole adapted to the shape of the connecting column 4. The mechanical knob 3 is connected to the second transmission component through the cooperation of the connecting column 4 and the connecting hole. The second transmission component is connected to the lock bolt 7, and the second transmission component is adapted to convert the rotational movement of the mechanical knob 3 into the horizontal movement of the lock bolt 7; both the first driving component and the door opener are electrically connected to the induction control module.

[0059] In this embodiment, the lock body module is installed on the compartment door through the lock body support 1 and the lock body cover 10, and includes an automatic unlocking and locking component and a manual unlocking and locking component, both of which can drive the lock bolt 7 to complete the unlocking and locking actions. The automatic unlocking and locking component includes a first driving component and a first transmission component. The working principle of the automatic unlocking and locking component is that after the induction control module receives an unlocking signal (such as a human body approach signal), it sends a control instruction to the first driving component. The first driving component (such as an electric motor) starts and outputs rotational or linear motion through its driving end. The first transmission component (such as gears, chains, or lead screws, etc.) converts the motion of the first driving component into a horizontal movement suitable for the lock bolt 7. The lock bolt 7 completes the horizontal movement under the action of the first transmission component, realizing the unlocking or locking of the door.

[0060] The manual unlocking and locking component includes a mechanical knob 3 and a second transmission component. The working principle of the manual unlocking and locking component is that the user manually rotates the mechanical knob 3. The cooperation of the connecting column 4 and the connecting hole ensures a reliable connection between the mechanical knob 3 and the second transmission component. The second transmission component converts the rotational movement of the mechanical knob 3 into a horizontal movement suitable for the lock bolt 7. The lock bolt 7 completes the horizontal movement under the action of the second transmission component, realizing the unlocking or locking of the door.

[0061] The working process of this embodiment is as follows: Under normal circumstances, when the user approaches the door, the induction control module receives a signal. The induction control module controls the first driving component to drive the lock bolt 7 to complete the unlocking action. After the door opener receives the signal, it drives the door to open. After the user passes through, the induction control module controls the door opener to drive the door to close and relocks the door through the first driving component.

[0062] In case of emergency or failure, the user can manually rotate the mechanical knob 3 to drive the second transmission component, and then move the bolt 7 to complete the unlocking action. After manual unlocking, the user can manually open the door.

[0063] Please refer to again Figure 1 , in some embodiments, the second transmission component includes: a cam 5 and a slider; a connecting hole is provided in the base circle part of the cam 5; the slider is arranged on the convex part of the cam 5; a vertical guiding hole 6 is provided on the bolt 7, and the slider is slidably connected with the guiding hole 6 in a matching manner.

[0064] In this embodiment, the user manually rotates the mechanical knob 3, and the connecting column 4 of the knob cooperates with the connecting hole in the base circle part of the cam 5 to drive the cam 5 to rotate. When the cam 5 rotates, its convex part pushes the slider to move along a specific track. Under the action of the convex part of the cam 5, the slider slides up and down in the guiding hole 6 of the bolt 7. At this time, the slider also has a left - right movement. The bolt 7 moves horizontally under the push of the left - right movement of the slider, so as to complete the unlocking or locking action.

[0065] Please refer to again Figure 1 , in some embodiments, limiting blocks are arranged on both sides of the cam 5. The limiting blocks can prevent the cam 5 from rotating or moving excessively, ensuring that it works within a safe operating range.

[0066] Please refer to again Figure 1 , in some embodiments, the driving component is the first motor 2, and the first transmission component includes: a gear 9 and a rack 8; the gear 9 is fixed on the rotating shaft of the first motor 2, the rack 8 is horizontally fixed on the bolt 7, and the gear 9 is connected with the rack 8 in a matching manner.

[0067] In this embodiment, the driving component is the first motor 2, and the first motor 2 provides rotational power through its rotating shaft. The gear 9 is fixed on the rotating shaft of the first motor 2 and rotates along with the rotation of the first motor 2. The rack 8 is horizontally fixed on the bolt 7 and cooperates with the gear 9. When the first motor 2 rotates, the gear 9 also rotates accordingly, and the meshing of the gear 9 and the rack 8 causes the rack 8 to move horizontally, thereby driving the bolt 7 to complete the horizontal movement.

[0068] Please refer to Figure 2 , in some embodiments, the door opener includes: a side - mounted door opener; the side - mounted door opener includes a motor assembly, a rotating arm 12 and a guide groove 11; the motor assembly includes a second motor 13, the second motor 13 is installed on the side of the compartment door and the rotating shaft of the second motor 13 is parallel to the rotating shaft of the compartment door 17; the guide groove 11 is horizontally installed on the compartment door; one end of the rotating arm 12 is fixedly connected with the rotating shaft of the second motor 13, and the other end is slidably connected with the guide groove 11.

[0069] In this embodiment, the motor assembly includes a second motor 13, which is installed on the side of the compartment door through a motor cover 14, and its rotation axis is parallel to the rotation axis of the compartment door. One end of the rotating arm 12 is fixedly connected to the rotation axis of the second motor 13, and the other end is slidably connected to the guide groove 11. The guide groove 11 is horizontally installed on the compartment door, and is used to guide the other end of the rotating arm 12 to move in the horizontal direction.

[0070] The working principle of the side-mounted door opener is: when the sensing control module receives a signal to open the door, the second motor 13 starts to rotate. When the rotating shaft of the second motor 13 rotates, it drives one end of the rotating arm 12 fixedly connected thereto to rotate. The other end of the rotating arm 12 slides in the guide groove 11. Since the guide groove 11 is installed horizontally, the other end of the rotating arm 12 will move horizontally along the guide groove 11. The horizontal movement of the rotating arm 12 will cause the compartment door to rotate around its rotation axis, thereby achieving the opening of the door. The opposite process achieves the closing of the door, that is, the second motor 13 rotates in the opposite direction, the other end of the rotating arm 12 moves in the opposite direction along the guide groove 11, and the compartment door is closed accordingly. The design of the side-mounted door opener allows the second motor 13 and the rotating arm 12 to be installed on the side of the compartment door without taking up additional space.

[0071] See also Figure 3 In some embodiments, the door opener also includes: a top-mounted door opener; the top-mounted door opener includes a motor assembly, a right-angle steering assembly, a rotating arm 12 and a guide groove 11; the motor assembly includes a second motor 13, the second motor 13 is installed above the compartment door and the rotating shaft of the second motor 13 is perpendicular to the rotating shaft of the compartment door; one end of the right-angle steering assembly is fixedly connected to the rotating shaft of the second motor 13, and the other end is fixedly connected to one end of the rotating arm 12; the guide groove 11 is horizontally installed on the compartment door 17; the other end of the rotating arm 12 is slidably connected to the guide groove 11.

[0072] In this embodiment, the motor assembly includes a second motor 13, which is installed above the compartment door 17 through a motor cover 14, and its rotation axis is perpendicular to the rotation axis of the compartment door 17. One end of the right-angle steering assembly is fixedly connected to the rotation axis of the second motor 13, and the other end is fixedly connected to one end of the rotating arm 12. The function of the right-angle steering assembly is to convert the vertical rotation movement of the second motor 13 into the horizontal rotation movement of the rotating arm 12. One end of the rotating arm 12 is fixedly connected to the right-angle steering assembly, and the other end is slidably connected to the guide groove 11. The guide groove 11 is horizontally installed on the compartment door, and is used to guide the other end of the rotating arm 12 to move in the horizontal direction.

[0073] The working principle of the top-mounted door opener 22 is as follows: When the induction control module receives a signal to open the door, the second motor 13 starts to rotate. When the rotating shaft of the second motor 13 rotates, it drives the right-angle steering component to rotate. The right-angle steering component converts the vertical rotational motion into a horizontal rotational motion. One end of the rotating arm 12 rotates together with the right-angle steering component, and the other end slides within the guide groove 11. The horizontal movement of the rotating arm 12 causes the compartment door to rotate around its rotation axis, thereby achieving the opening of the door. The reverse process achieves the closing of the door, that is, the second motor 13 rotates in the reverse direction, and the other end of the rotating arm 12 moves in the opposite direction along the guide groove 11, and the compartment door closes accordingly.

[0074] Please refer to again Figure 3 , in some embodiments, the right-angle steering component includes: a first bevel gear 15 and a second bevel gear 16; the first bevel gear 15 is fixedly connected to the rotating shaft of the second motor 13; the second bevel gear 16 is fixedly connected to one end of the rotating arm 12; the axes of the first bevel gear 15 and the second bevel gear 16 are perpendicular to each other and the first bevel gear 15 and the second bevel gear 16 are cooperatively connected.

[0075] In this embodiment, the first bevel gear 15 is fixedly connected to the rotating shaft of the second motor 13 and rotates with the rotation of the second motor 13. The second bevel gear 16 is fixedly connected to one end of the rotating arm 12, and its axis is perpendicular to the axis of the first bevel gear 15. The axes of the first bevel gear 15 and the second bevel gear 16 are perpendicular to each other, and the two are connected by meshing of tooth surfaces. When the first bevel gear 15 rotates, it drives the second bevel gear 16 to rotate. Through the cooperation of the first bevel gear 15 and the second bevel gear 16, the vertical rotational motion of the second motor 13 can be efficiently converted into the horizontal rotational motion of the rotating arm 12.

[0076] Please refer to again Figure 2 or Figure 3 , in some embodiments, a roller is provided at the other end of the rotating arm 12, and the rotating arm 12 slides within the guide groove 11 through the roller. The roller can reduce friction. By rolling the roller within the guide groove 11, the friction between the rotating arm 12 and the guide groove 11 can be significantly reduced, making the opening and closing of the door smoother.

[0077] Please refer to Figure 4 and 5 , in some embodiments, the induction control module includes: an outer inductor 19, an inner inductor 20, and a control module; the outer inductor 19 is installed on the outer side of the compartment door 17; the inner inductor 20 is installed inside the compartment door 17; both the outer inductor 19 and the inner inductor 20 are connected to the control module.

[0078] In this embodiment, the outer sensor 19 is installed on the outer side of the compartment door 17 for detecting the approach or departure of an external user. The inner sensor 20 is installed inside the compartment door 17 for detecting the approach or departure of an internal user. Both the outer sensor 19 and the inner sensor 20 are connected to the control module. The control module receives signals from the outer sensor 19 and the inner sensor 20 and controls the opening and closing of the door according to these signals. The door opener 22 is installed between the door frame 18 and the compartment door 17, and the lock body module 21 is installed on the compartment door 17.

[0079] In some embodiments, it further includes: a status display module; the status display module is connected to the induction control module. The status display module can display the current status of the door according to the status information of the control module, such as "open", "closed", "fault", etc.
