[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The present invention provides a technical solution: a foldable luminous menu, comprising: a first leather case 1, a second leather case 2, a first backlight module 4 and a second backlight module 5, wherein the first leather case 1 is wrapped around the first backlight module 4 and the second leather case 2 is wrapped around the second backlight module 5.

[0025] A folding sleeve 3 connects the first sleeve 1 and the second sleeve 2. An FPC flexible circuit board 10 connects the first backlight module 4 and the second backlight module 5. The FPC flexible circuit board 10 extends laterally through the folding sleeve 3, enabling the folding of the first backlight module 4 and the second backlight module 5. The folding sleeve 3 eliminates the tensile force when the first sleeve 1 and the second sleeve 2 are folded, which can significantly improve the service life of the folding. The FPC flexible circuit board 10 also has a longer service life than traditional wires.

[0026] Specifically, the first leather case 1 and the second leather case 2 are provided with hollow areas, so that the upper surface of the first backlight module 4 and the second backlight module 5 is exposed. The upper end of the first leather case 1 and the second leather case 2 is provided with a slot 6 for inserting a menu page. The length and width of the menu page are larger than the hollow areas of the first leather case 1 and the second leather case 2 to prevent the menu page from falling off. The first backlight module 4 and the second backlight module 5 emit light to make the menu backlit and display, so that the user has a better experience using the menu.

[0027] The folding leather case 3 has symmetrical edge banding 31 on both sides. The edge banding 31 wraps around the adjacent edges of the first leather case 1 and the second leather case 2 respectively, and is fixed by glue or other means.

[0028] Both the first backlight module 4 and the second backlight module 5 have an opaque base plate 9 at their bottom and a frame 7 around them. The opaque base plate 9 and the frame 7 serve to protect the edges of the backlight modules.

[0029] Both the first backlight module 4 and the second backlight module 5 are covered with a diffuser 8, and an LED light strip 11 is fixedly installed on the adjacent side of the first backlight module 4 and the second backlight module 5.

[0030] The first backlight module 4 and the second backlight module 5 include a light guide plate. The LED light strip 11 shines light onto the light guide plate and then emits light evenly through the diffuser 8. The lower right corner of the light guide plate of the first backlight module 4 is embedded with a sub-circuit board 41 and a magnet 42. The lower part of the light guide plate of the second backlight module 5 is embedded with a main control circuit board 52 and a battery 51. The sub-circuit board 41 and the main control circuit board 52 are connected through an FPC flexible circuit board 10. The sub-circuit board 41 and the main control circuit board 52 are electrically connected to the LED light strip 11. The main control circuit board 52 is electrically connected to the battery 51. The main control circuit board 52 includes a reed switch. The reed switch is inductively connected to the magnet 42. In the folded state, the reed switch is closed under the magnetic field of the magnet 42, and the LED light strip 11 is not powered. In the open state, the reed switch is open, and the sub-circuit board 41 and the main control circuit board 52 supply the power of the battery 51 to the LED light strip 11, making it emit light.

[0031] The main control circuit board 52 also includes a charging interface 521, which is used to connect to a power source to charge the battery 51.

[0032] Working principle: The first backlight module 4 and the second backlight module 5 respectively wrap the first leather sleeve 1 and the second leather sleeve 2 to form the first menu and the second menu. After the FPC flexible circuit board 10 is connected to one of the modules, the FPC flexible circuit board 10 is passed through the folded leather sleeve 3 and connected to the other module. The folded leather sleeve 3 is glued and fixed to connect the first menu and the second menu together. Then the menu page is inserted from the slot 6 to complete the product assembly.

[0033] When the first and second menus are folded, the magnet 42 on the first backlight module 4 covers the reed switch on the main control circuit board 52, triggering the reed switch, breaking the circuit of the main control circuit board 52, and turning off the LED light strip 11.

[0034] When the first and second menus are unfolded, the magnet 42 on the first backlight module 4 disengages from the reed switch on the main control circuit board 52, the reed switch resets, the main control circuit board 52 is powered on, the LED light strip 11 is powered on and illuminates the menu page.

[0035] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
