Description

Technical Field

[0001] The utility model belongs to the field of coal mine auxiliary transportation equipment, in particular to a mouse control device based on coal mine remote control. Background Art

[0002] In recent years, driven by the trend toward intelligent coal mining, a wide range of intelligent equipment, such as remote controls and unmanned driving, has been gradually introduced underground. Due to the practical requirements of underground equipment's operating environment and operational techniques, the use of remote controls and mice has increased significantly. Intrinsically safe remote controls for mines are now being used on intelligent coal mining equipment, including fully automatic hydraulic drills, fully automatic anchor drills, integrated anchoring and drilling machines, and trackless rubber-tyred vehicles. Currently, due to the complex gas content underground in coal mines and the high concentrations of methane present at most excavation faces, electrical products are prone to sparks, requiring explosion-proof treatment. This is particularly true for physical buttons in explosion-proof products, which play a critical role in underground coal mines. Their primary functions include setting vehicle parameters, switching interfaces, and displaying alarm messages. The design of physical buttons in underground electrical control boxes often requires consideration of the roughness and clearance of the explosion-proof mating surfaces, resulting in high processing and assembly difficulties. To solve the above problems, a wireless mouse is used to switch the human-machine interface, and the USB interface of the display component inside the explosion-proof box is retained or a communication to USB interface is used so that the wireless mouse receiver can be directly plugged in to replace the physical buttons of the original electric control box.

[0003] The intrinsically safe mine mouse (hereinafter referred to as the mouse) is a practical tool that plays a vital role in underground coal mine equipment. However, coal mine equipment often operates in harsh and complex environments. The mouse housing is made of polyvinyl chloride (PVC), which is lightweight but has poor impact resistance. Furthermore, the high concentration of dust and coal slag in the underground mine environment makes the mouse prone to loss and damage. Therefore, in the context of intelligent coal mines, a highly integrated two-in-one remote control and mouse device is needed to address these issues and enhance the intelligence of coal mine equipment.

The direction and amplitude of the universal joystick control the direction and speed of the mouse pointer, and pressing the universal joystick activates the mouse click function. This solves the problem of small electronic devices being easily lost when carried with coal mine equipment, while also increasing the transmission distance through wireless communication. This further enhances the integration and intelligence of coal mine products.

[0005] To achieve the above-mentioned purpose, the utility model provides a mouse control device based on coal mine remote control, including a knob part and a universal joystick part, the knob part is arranged on one side of the universal joystick part, the knob part is electrically connected to the universal joystick part, the universal joystick part includes a rocker, a brush, a rocker bracket, a resistance track, a circuit board button, an operation panel and a spring, the circuit board button is arranged in the operation panel, and the circuit board button is abutted and connected with the resistance track above, one end of the rocker bracket is arranged in the operation panel and covers the circuit board button and the resistance track above, the other end of the rocker bracket passes through the upper surface of the control panel, the rocker is arranged in the rocker bracket, and a brush is arranged at the bottom of the rocker, the brush is slidingly arranged in the resistance track, and the rocker upper sliding sleeve between the brush and the rocker bracket is provided with a spring.

[0006] Furthermore, the knob portion is provided with a spare gear position for expanding and providing additional functional operations.
