Description

Technical Field

[0001] The present invention relates to the technical field of a touch screen display of a fuel dispenser, and in particular to a touch screen display of a fuel dispenser and a display device thereof. Background Art

[0002] Fuel dispensers have developed along with the development of automobiles and road traffic. They are sales terminals in the retail industry of refined oil and metering equipment used for sales settlement. At present, all fuel dispensers on the market are equipped with integrated touch screens, which can display the amount of fuel and the cost as well as control the refueling by the user. However, the touch screens on fuel dispensers are mostly directly set. When refueling, the user needs to open the fuel tank cap on the vehicle, which makes it easy for the hands to adhere to oil stains, resulting in the oil stains adhering to the touch screen when operating the touch screen. In order to ensure the sensitivity of the display operation and clear display, the display needs to be cleaned regularly. There are currently two cleaning methods, one is an automatic cleaning device integrated on the touch screen, and the other is manual cleaning.

[0003] For example, the application authorization announcement number is CN110264896B, the authorization announcement date is March 23, 2021, and the invention patent is named "A high-efficiency self-cleaning outdoor LED display screen", which specifically includes an automatic screen cleaning device, a display screen body, and a display screen box. The display screen box is equipped with a display screen body, and the display screen body is provided with an automatic screen cleaning device mechanically connected to the display screen box; the automatic screen cleaning device includes an energy-saving motor, a screw group, an automatic screen cleaning mechanism, and a guide support rod. The top of the automatic screen cleaning mechanism is fixedly connected to the screw group, and the bottom is slidably connected to the guide support rod. The screw of the screw group is connected to the output shaft of the energy-saving motor.

[0004] As in the above application, when the touch screen of the gas station is contaminated with oil, whether the touch screen is automatically cleaned by the automatic cleaning device integrated on the display body in the above application, or manually cleaned by staff using a spray bottle to spray detergent, it is easy for the cleaning liquid to penetrate into the frame of the touch screen, causing the touch screen to become damp and malfunction, thus affecting the service life of the touch screen.

Optionally, when in use, the staff can watch and touch the touch screen body 1 through the touch protection film 22 to prevent the oil stains adhered to the staff's hands from directly contaminating the touch screen body 1. When the touch protection film 22 is adhered to the oil stains, the adjustment mechanism 5 drives the winding mechanism 2 to pull and rewind the touch protection film 22, and cooperates with the unwinding mechanism 3 to unwind, so as to switch the touch protection film 22. After the touch protection film 22 is switched, the adjustment mechanism 5 switches to drive the two clamping and laminating mechanisms 4 (at this time, the winding mechanism 2 is no longer driven to pull and rewind the touch protection film 22). , that is, the touch protection film 22 remains stationary at this time), the two clamping and bonding mechanisms 4 clamp the touch protection film 22 from the two sides of the touch protection film 22 respectively, and stretch the touch protection film 22 to fit the surface of the touch display screen body 1 tightly, so as to avoid the surface of the touch display screen body 1 from adhering to oil stains for cleaning, and to prevent the cleaning liquid from penetrating into the interior of the touch display screen body 1 to cause malfunction thereof, and at the same time make the touch protection film 22 fit smoothly on the touch display screen body 1, so as to prevent the touch protection film 22 from wrinkling and affecting the sensitivity of the touch operation and the viewing effect.

When the touch protection film 22 is switched as a whole once, the driving toothed disc 52 rotates to the position of avoiding the notch 521. At this time, the driving toothed disc 52 continues to rotate without rotating the driving adjustment gear 23. At this time, the driving convex teeth 531 in the arc-shaped interval on the driving gear 53 coaxially fixed on the driving toothed disc 52 are aligned with the adjustment gear 23. The protruding teeth 452 are meshed, so that the L-shaped adjustment frame 451 is driven to move by adjusting the protruding teeth 452, and the L-shaped adjustment frame 451 drives the clamping plate 44 to fit to the side of the clamping bottom plate 43 to clamp the side of the touch protection film 22, and then the L-shaped adjustment frame 451 continues to move, thereby driving the clamping plate 44 to cooperate with the clamping bottom plate 43 to move synchronously to the side plate 41, so as to achieve the tensioning and laminating of the clamped touch protection film 22 on the touch display screen body 1, and prevent the touch protection film 22 from wrinkling, which affects the sensitivity of the touch operation and the viewing effect. At the same time, the adjustment mechanism 5 is realized by a driving unit to realize automatic intermittent switching to drive the winding mechanism 2 and the clamping and laminating mechanism 4 to automatically cooperate to realize the winding switching of the touch protection film 22 and the tensioning and laminating of the touch display screen body 1, thereby reducing the use of power and reducing costs. At the same time, there is no need for monitoring equipment to control the winding mechanism 2 and the clamping and laminating mechanism 4 to cooperate with each other to improve the overall smoothness.

The linkage adjusting member 7 includes an adjusting disk 73 and a movable gear rack 71. The adjusting disk 73 is coaxially fixed to the end of the roller 24, and a plurality of arc-shaped teeth 74 are evenly spaced on the circumference of the adjusting disk 73. The movable gear rack 71 is slidably arranged on the rectangular box body 21, and one end of the movable gear rack 71 is connected to the guide adjusting roller 62, and the movable gear rack 71 is meshed with the arc-shaped teeth 74. The tail end of the movable gear rack 71 is connected to a reset spring 72. When the roller 24 in the winding mechanism 2 rotates to rewind the touch protection film 2 2, the roller 24 synchronously drives the adjustment disk 73 to rotate, and an arc-shaped tooth portion 74 on the adjustment disk 73 drives the movable gear rack 71 to slide, and the movable gear rack 71 drives the guide adjustment roller 62 to move. At the same time, when the arc-shaped tooth portion 74 separates from the movable gear rack 71, the reset spring 72 drives the movable gear rack 71 to reset the guide adjustment roller 62, thereby driving the guide adjustment roller 62 to slide back and forth, and finally driving the touch protection film 22 to swing back and forth through the guide adjustment roller 62, so as to drive the touch protection film 22 to swing back and forth when laying the touch protection film 22, and finally, the dust and impurities on the surface of the touch display screen body 1 are cleaned through the swing of the touch protection film 22, so as to prevent the dust adhering to the surface of the touch display screen body 1 from affecting the sensitivity of the operation after the touch protection film 22 is attached.
