DETAILED DESCRIPTION

[0028] like Figures 1 to 4 As shown, the utility model provides a mining intrinsically safe remote control transmitter for long-distance wireless control of hydraulic support actions, including a front shell 4 and a rear shell 12, the front shell 4 and the rear shell 12 are fixedly connected by screws to form an integral remote control transmitter, wherein the outer surface of the front shell 4 is sequentially provided with a key guard plate 1, a silicone key membrane 2 and a key assembly 3 from the outside to the inside, wherein the silicone key membrane 2 covers the key assembly 3, the key guard plate 1 is arranged on the silicone key membrane 2, and the key assembly 3 and the silicone key membrane 2 are fixed to the front shell 4 by the key guard plate 1. The key assembly 3 uses a membrane key, which can greatly reduce the thickness of the entire shell; covering the membrane key with a silicone key membrane 2 can not only protect the membrane key, but also increase the touch when the key is operated; the corresponding area of ​​each key on the silicone key membrane 2 is printed with a corresponding key name, and then a protective layer is formed on each key name on the upper surface of the silicone key membrane 2 through a drop molding process, which can protect the key from being worn out after multiple uses and can also enhance the toughness of the key; at the same time, adding a key guard plate 1 on the upper surface of the silicone key membrane 2 can further protect the key. The key guard plate 1 is made of aluminum alloy.

[0029] The back of the front shell 4 is divided into two parts: a display area and a key area. Different areas are separated by ribs. The inner edge of the display area is affixed with adhesive 6, which is used to fix the protective window 7. The protective window 7 is equipped with a display screen 13. A groove is provided on the shell on the right side of the display screen 13. The groove is equipped with an antenna 8 for transmitting signals. Nuts are buried around the display area, and the main board 9 is installed on the back of the display screen 13 through nuts. The key area is respectively equipped with a wireless charging receiving module 11 and a battery 5.

[0030] A sealing groove is reserved on the front shell 4, and the sealing ring 10 is pre-set in the sealing groove and is lower than the surface of the sealing groove as a whole. The rear shell 12 has ribs of matching shape corresponding to the sealing groove reserved by the front shell 4 to squeeze the sealing ring.

[0031] The front shell 4 and the rear shell 12 are set to be slender in shape, which is convenient for one-handed operation. Specifically, the front shell 4 and the rear shell 12 are structures that are wide at the top and narrow at the bottom. The upper part where the display screen is installed is a horizontal rectangle, and the lower part where the key assembly 3 is installed is a vertical rectangle, and the width of the lower rectangle is smaller than the length of the upper rectangle. Both sides of the shell are provided with undulating ridges and concave grooves, which fit the shape of human hand holding, making it easy for fingers to grasp and not easy to slip out of the hand.

[0032] A round hole is provided on the rear shell 12 for inserting a lanyard, and the setting of the lanyard can facilitate the hand-carrying of the remote control transmitter. A charging contact is provided at the bottom of the remote control transmitter as a whole, which can contact the charging probe in the charging seat for charging. At the same time, the utility model is provided with a wireless charging receiving module 11, which can contact the wireless charging seat to realize wireless charging. The wireless charging receiving module 11 can adopt the ROHM BP3621 transmitting end module, and the corresponding wireless charging seat is provided with the ROHM BP3622 receiving end module.

[0033] The mainboard 8 of the utility model is integrated with a power module, a microcontroller, a wireless communication module and a corresponding control circuit. The microcontroller is connected to the wireless charging receiving module 11, the wireless communication module and the power module through wires respectively. The power module is connected to the battery 5. The communication between the remote control transmitter and the hydraulic support controller is realized through the wireless communication module. The mainboard 8 is also integrated with an acceleration sensor chip. The microcontroller is also connected to the acceleration sensor chip through a wire. The acceleration sensor chip can be used to protect the remote control transmitter from falling. Specifically, when the remote control transmitter falls, the acceleration sensor chip will detect a sudden change in its acceleration. At this time, the microcontroller will control the remote control transmitter to automatically shut down, thereby realizing the fall protection of the remote control transmitter. Automatically shutting down the remote control transmitter after it falls also avoids the possibility of erroneous operation of buttons when it contacts the ground, resulting in the action of the hydraulic support being triggered by mistake, thereby realizing safe and effective control of the hydraulic support.

[0034] In order to meet the anti-static and flame-retardant requirements when used underground in mines, the front shell 4 and the rear shell 12 of the utility model are made of flame-retardant plastic combined with conductive materials. However, in order to prevent the charging contacts from making contact with the charging seat during charging and causing the entire remote control transmitter to be charged, an insulating kit is provided at the part where the charging contacts are in contact with the front shell 4 and the rear shell 12. The insulating kit can ensure safety during charging.

[0035] The display screen 13 of the utility model can display data such as working surface information, support posture information and controller parameters, thereby achieving comprehensive control of the hydraulic support.
