[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The utility model relates to a preferred embodiment of a light guide plate structure.

[0033] See also Figures 1 to 6The light guide plate structure includes a first layer plate, a second layer plate and a third layer plate which are arranged in sequence, the first layer plate is a cover plate 100, the second layer plate is a light source plate 200, and the third layer plate is a reinforcing plate 300.

[0034] The cover plate 100 is provided with a plurality of mounting through holes 110, the light source plate 200 is provided with a plurality of mounting through holes 210, and the reinforcing plate 300 is provided with a plurality of mounting through holes 3 210. The apertures and positions of the mounting through holes 110, 210 and 310 are arranged corresponding to each other for installing knobs or buttons.

[0035] The side panels around the cover plate 100 enclose an inner cavity 120, the outer dimensions of the light source panel 200 are adapted to the shape and dimensions of the inner cavity 120 of the cover plate 100, the light source panel 200 is embedded in the inner cavity 120 of the cover plate 100, and the reinforcing panel 300 is compositely connected to the cover plate 100 with the light source panel 200 embedded therein to form a whole.

[0036] In an exemplary embodiment, the cover plate 100 is a polycarbonate plate. The polycarbonate plate has light weight, good strength, good light diffusion performance, and fire retardant properties that can meet the relevant requirements of EN45545-2, HL2 and above, and meets the standards for use of motor vehicles. The polycarbonate plate is machined to form a mounting through hole of a designed size on the back of the plate.

[0037] Furthermore, the polycarbonate plate can be made into different colors according to requirements, and identification information such as text, numbers or pattern LOGO is engraved at corresponding positions on the surface of the polycarbonate plate. The identification information is formed around the knob or button to identify different gears.

[0038] In an exemplary embodiment, the light source board 200 has a front side and a back side opposite to each other. The front side of the light source board 200 is provided with LED particles 220 , and the back side of the light source board 200 is provided with an external power input interface 230 .

[0041] The light source panel 200 directs light to the polycarbonate panel through the LED particles 220. Since the polycarbonate panel has good light diffusion properties, it can diffuse point light sources into surface light sources, providing a good lighting environment for the operating console in the driver's cab, which not only ensures that the driver can clearly observe various instruments and equipment during driving, but also improves the product grade.

[0042] Furthermore, the external power input interface 230 is disposed protruding from the back of the light source panel 200 , and different voltage inputs are realized through the external power input interface 230 .

[0043] In an exemplary embodiment, the reinforcing plate 300 is a metal reinforcing plate. Preferably, the metal reinforcing plate is an aluminum plate.

[0044] Since the first layer of polycarbonate plate will be slightly deformed after processing, the third layer of reinforcement plate is made of metal plate and is composited with the first layer of polycarbonate plate through screws to form a whole. In this way, the deformation of the first layer of polycarbonate plate can be reduced through the composite of the metal reinforcement plate, ensuring the flatness of the product and ensuring that there will be no bulging when the product is installed on the operating table.

[0045] In the present invention, the left and right ends of the reinforcing plate 300 are further provided with external through holes 320 for installation and fixation of the light guide plate structure.

[0047] The beneficial effects of the light guide plate structure and the driver's cab control panel of the utility model are:

[0048] The structure is simple, the appearance is concise, and the control panel can be illuminated in multiple colors, which improves the product grade and competitiveness and achieves cost reduction and efficiency improvement;

[0049] The integrated composite structure can reduce product deformation, ensure flatness, and prevent bulging after installation;

[0050] It can provide a good lighting environment for the control panel, ensuring that the driver can clearly observe various instruments and equipment during driving.
