[0010] Furthermore, it also includes a drag chain, one end of which is connected to the shell through a connecting plate, and the other end is connected to the main body through a fixing member; the interior of the drag chain is used to store wires.

[0016] The utility model achieves locking of the main body through an electromagnetic lock, and adds a transmission component so that the main body can automatically slide in the shell to achieve opening and closing of the main body. When the main body needs to be ejected from the shell, the electromagnetic lock is first opened, and the stepper motor drives the main body to move outward in the forward direction. When the main body needs to enter the shell, the stepper motor reverses to make the main body move inward, and after moving to the innermost side, the electromagnetic lock locks the main body. In this way, people no longer need to apply pulling force to the main body, and even apply pulling force to the main body when the body posture is uncomfortable, which damages the main body and reduces the life of the main body. In addition, when the main body is pushed into the shell, the hand will not be pinched inadvertently, causing harm to people. The utility model realizes the automatic opening and closing of the drawer, simplifies the steps of opening and closing the drawer, and prevents the occurrence of injuries when closing the drawer.

[0022] like Figures 1 to 5 As shown, an automatic opening and closing drawer with an electromagnetic lock includes a main body 1, a shell 2, a drag chain 3, a sensor 4 and a controller; the shell 2 has a cavity, and the main body 1 is moved in the cavity through a transmission assembly 9; the shell 2 is provided with an electromagnetic lock 5, and the main body 1 is provided with a lock nose 6, and the lock nose 6 is adapted to the electromagnetic lock 5; the two sides of the main body 1 are installed on the shell 2 through three-section tracks 7, and the three-section tracks 7 can increase the smoothness and movement distance of the main body 1. The lock nose 6 is provided with a locking ring 8, when the electromagnetic lock 5 restricts the movement of the locking ring 8, the main body 1 cannot move in the cavity, and when the electromagnetic lock 5 does not restrict the movement of the locking ring 8, the main body 1 can move in the cavity. The sensor 4 is fixed in the shell, and the sensor 4 is used to provide a relative position signal between the main body 1 and the shell 2. The sensor 4 includes a first sensor 4 and a second sensor 4, and the first sensor 4 can provide a position signal when the main body 1 moves toward the outside of the shell 2, and the second sensor 4 can provide a position signal when the main body 1 moves toward the inside of the shell 2. The controller is electrically connected to the electromagnetic lock 5, the stepper motor and the sensor 4; the controller can control the opening and closing of the electromagnetic lock 5, the controller can control the speed and rotation direction of the stepper motor, and the controller can receive the position signal provided by the sensor 4. When the main body 1 needs to be opened, the controller sends a signal to the electromagnetic lock 5 so that the electromagnetic lock 5 releases the restriction on the locking ring 8, and then the controller sends a signal to the transmission component 9 so that the transmission component 9 pushes the main body 1 to move to the outside of the shell 2. When the first sensor 4 reaches the specified position and sends a position signal to the controller, the controller sends a signal to the transmission component 9 to reduce the movement speed of the main body 1, reduce the impact force and extend the service life of the components. When the main body 1 needs to be closed, the controller sends a signal to the transmission component 9 so that the transmission component 9 drives the main body 1 to move to the inside of the shell 2. When the second sensor 4 reaches the specified position and sends a position signal to the controller, the controller sends a signal to the transmission component 9 to reduce the movement speed of the main body 1, reduce the impact force and extend the service life of the components. Finally, the controller sends a signal to the electromagnetic lock 5, and finally the electromagnetic lock 5 restricts the movement of the locking ring 8.
[0023] The transmission assembly 9 includes a stepper motor 11, a driving wheel 12, a driven wheel 13 and a synchronous belt 14; the stepper motor 11 is installed on the housing 2 through a sliding assembly, the output end of the stepper motor 11 is connected to the driving wheel 12, and the driving wheel 12 is connected to the driven wheel 13 through the synchronous belt 14; a push plate 15 is connected to the synchronous belt 14, and the push plate 15 is connected to the main body 1. The sliding assembly includes a slider 16 and a slide rail 17, the slider 16 is connected to the push plate 15, the slide rail 17 is fixed on the housing 2, and the slider 16 is adapted to the slide rail 17. The stepper motor 11 drives the driving wheel 12 to rotate, and the driving wheel 12 drives the driven wheel 13 to rotate through the synchronous belt 14. When the synchronous belt 14 moves, it drives the main body 1 to move through the push plate 15, so that the main body 1 can be opened and closed automatically.
[0024] A set of fixing brackets 21 and connecting brackets 22 are respectively provided on both sides of the shell 2, and each connecting bracket 22 is fixed to the shell 2 through the fixing bracket 21; each connecting bracket 22 is respectively connected to the three-section track 7; and a connecting plate 23 is provided in the shell 2. A fixing plate 24 is provided on the main body 1, and there is a gap between the fixing plate 24 and the main body 1. The push plate 15 is inserted in the gap, and the push plate 15 can move left and right in the gap. Three-section tracks 7 are provided on both sides of the main body 1, and a transmission assembly 9 is provided at the bottom of the main body 1, so that the movement trajectory of the main body 1 is a straight line, which requires that the parallelism of the three straight lines on both sides and the bottom of the main body 1 is extremely high, which will undoubtedly increase the difficulty of assembly and assembly process. By providing a gap between the fixing plate 24 and the main body 1, the push plate 15 can move left and right in the gap, so that the stepping motor 11 only needs to provide power, and the main body 1 will not be able to move only in one straight line, which greatly reduces the requirements for parallelism, and only needs the three-section tracks 7 on both sides to be parallel. Since the three-section track 7 is in relative motion, it has a movable gap, which greatly reduces the difficulty and process of assembly. One end of the drag chain 3 is connected to the housing 2 through a connecting plate 23, and the other end is connected to the main body 1 through a fixing member; the inside of the drag chain 3 is used to store wires. The main body 1 has a cavity, and a mounting plate 26 is provided in the cavity. The mounting plate 26 is provided with a plurality of fixing holes 25 of different specifications. The different fixing holes 25 are used to prevent objects of different specifications, and can play a fixing role, so that the object will not tip over or tip over due to automatic movement.
[0025] The three-section track 7 includes a primary track, a secondary track and a tertiary track; one side of the primary track is connected to the main body 1, and the other side is connected to the secondary track; the secondary track makes the primary track and the tertiary track slidably connected, and the tertiary track is fixedly connected to the connecting bracket 22; the primary track and the tertiary track are respectively provided with a limit plate, and the limit plate is used to limit the movement of the secondary track. When the main body 1 starts to move outward, it first drives the primary track to slide relative to the secondary track. When the secondary track slides to the limit plate of the primary track, the secondary track will slide relative to the tertiary track, increasing the movement distance of the main body 1. When the secondary track moves to the limit plate of the tertiary track, it will stop moving to prevent the secondary track from falling off from the tertiary track.
[0026] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
