[0002] With the increasing number of mechanical equipment installed with protective devices, mobile sliding doors, as the mainstream door type of protective devices, have been popularized in various mechanical equipment. Sliding doors are driven by electromechanical and manual methods. Heavy sliding doors are mainly driven by electromechanical method due to their own weight. The control method is to control the equipment operation station with two buttons of open and close to control the full opening and closing of the sliding door. This method has the problems of inconvenient operation and inflexible opening state of the door. In real life, there is an urgent need to find a structural device that can realize manual, light and flexible control of the opening and closing of the sliding door. Summary of the invention

[0003] The object of the present invention is to provide a door handle with an electromechanical drive device switch built in to address the deficiencies in the existing designs.

[0004] The switch handle of the movable door assist device described in the present invention is a door handle with an electromechanical switch, and its main components include a handle body, a handle seat, a support screw, a push-type potentiometer, a potentiometer support, a lever, a shoulder screw, a power button, a reset device, etc. The support screw is placed in the handle body, and the handle body and the support screw are connected by an upper and lower shoulder screw, and the screw rod of the support screw passes through the handle seat, the door panel and the potentiometer support (the potentiometer support is installed at one of the two installation points) in turn, and then the nut is screwed on to install it on the door panel. A certain rotation space is provided between the handle body and the handle seat, and the installation is stable and without shaking. A lever extends from the handle body and passes through the handle seat and the door panel, and forms a lever with the handle body with the shoulder screw as the center, and swings in the opposite direction to the handle grip; the potentiometer support is a symmetrical structure with three-sided folded edges, and the middle folded edge is installed in contact with the back of the door panel, and a reset device is provided on the middle bottom panel (that is, the middle folded edge installed in contact with the back of the door panel). The lever is located between the two potentiometers, ensuring that the swing of the lever can effectively press the potentiometer to control the potentiometer, wherein the potentiometers on both sides are connected to the motor inverter to respectively control the forward and reverse rotation of the sliding door drive motor, and the swing of the door handle acts on the drive motor with the direction and the swing angle as variables, thereby realizing the control of the door handle over the door; a power button is provided on the handle grip, and the power button is connected to the inverter to control the connection and disconnection of the circuit, and the power button can be a power button with a light, which plays an insurance role in the control of the door handle over the door through the indicator light on the button.

[0005] The movable door assist device switch handle of the present invention combines the advantages of manual and motorized types, places the switch of the electromechanical drive device in the door handle, and cooperates with the reasonable design of the movable door switch handle, so that in the process of manually pushing and pulling the door, the motorized drive mechanism can be automatically started without complex electromechanical structure and high cost, thereby realizing manual, light and flexible control of the opening and closing of the sliding door. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] Figure 1 It is a longitudinal cross-sectional view of the present invention;

[0007] Figure 2 for Figure 1 AA horizontal section view with action diagram in the middle.

[0008] The numbers of the main components in the figure include: 1. handle body, 2. handle seat, 3. support screw, 4. potentiometer, 5. potentiometer support, 6. lever, 7. shoulder screw, 7', nut, 8. spring, 9. power button, 10. handle plug; 11. movable door panel. DETAILED DESCRIPTION

[0009] The handle structure of the present invention is further explained below in conjunction with the accompanying drawings.

[0010] Figure 1 is a side sectional view of the present invention, Figure 2 The AA-axis cross-sectional view with a schematic diagram of the parts' movements is shown in the figure. As shown in the figure, the main components include: handle body 1, handle base 2, support screw 3, potentiometer 4, potentiometer support 5, lever 6 (integrated with the handle body), shoulder screw 7, nut 7', spring 8, power button 9, handle plug 10; the reference numeral 11 in the figure is an auxiliary diagram of the movable door panel 11. The support screw 3 is set in the support foot of the handle body 1 and is connected by the shoulder screw 7, wherein the support screw 3 can swing within a certain range (such as the shoulder screw 7 as the center) Figure 2 ), the screw of the support screw 3 passes through the handle seat 2, the door panel 11 and the potentiometer support 5 in sequence and then is fixed by the nut 7'. During the process, it is necessary to ensure that the lever 6 of the handle body 1 passes through the hook of the spring 8 to play an auxiliary resetting role of the handle; the potentiometer support 5 is a steel plate with a three-sided folded symmetrical structure, and the potentiometer 4 is a push-type potentiometer 4, which is installed on the potentiometer support 5. The pressing surface of the potentiometer 4 is just in contact with the lever 6 by adjusting the nut 7'. The potentiometer 4 is connected to the motor inverter to control the forward and reverse rotation of the motor respectively, wherein it must be ensured that the driving direction of the motor to the door is consistent with the swing direction of the handle, and the power button 9 can be a power button with a light, which is connected to the inverter to control the operation and shutdown of the potentiometer 4 and play a control insurance role, wherein the wiring is used to ensure that the lighting and extinguishing of the prompt light of the power button 9 are consistent with its working control state of the potentiometer.
