Description

Technical Field

[0001] This utility model relates to the field of backlight module technology, specifically to a backlight module with multi-mode triggering function. Background Technology

[0002] Backlight modules rely on light-emitting panels to present information. This static display method has a relatively simple visual effect and is difficult to quickly attract users' attention in different environments. In particular, its expressiveness is greatly reduced in display scenarios with dim lighting or intense competition.

[0003] For example, patent CN220691227U discloses a backlight module including a light-emitting substrate and a mid-frame. The light-emitting substrate includes a rigid base plate and light-emitting devices disposed on the rigid base plate. A groove is formed on the side plate of the mid-frame to limit the rigid base plate. During assembly, the deformation of the mid-frame is used to install the edge of the rigid base plate into the groove of the side plate, so that the rigid base plate is directly fixed to the mid-frame, resulting in a simple structure and easy assembly.

[0004] However, the above technologies have the following problems: they lack dynamic display functions, cannot increase the fun of the experience through interaction, and are difficult to meet the needs of modern diverse scenarios. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a backlight module with multiple triggering modes.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0012] Furthermore, the contact triggering module includes a spring and a contact, and the main frame has a slot, with one end of the spring fixedly connected to the inside of the slot and the other end of the spring fixedly connected to the contact.

[0017] Compared with the prior art, the advantages of this utility model are as follows: Visually, this utility model enhances the image display effect by combining the light-emitting plate with the notch of the card image, making it eye-catching in different environments, and also creating an immersive atmosphere and improving the experience;

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0033] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-9 A backlight module with multiple triggering modes includes a device body 1, a contact triggering module 2, and a rotation triggering module 3;

[0034] The main body 1 of the device is connected to the contact trigger module 2, and the back of the main body 1 is connected to the rotation trigger module 3.

[0035] The main body 1 of the device includes a light-emitting panel 11, a selector switch 12, a circuit board 13, a power supply 14, a main frame 15, and a push switch 16. The circuit board 13 and the power supply 14 are both electrically connected to the selector switch 12. The light-emitting panel 11, the selector switch 12, the circuit board 13, the power supply 14, and the push switch 16 are all fixedly installed inside the main frame 15. One end of the push switch 16 is electrically connected to the positive terminal of the power supply 14, and the other end of the push switch 16 is electrically connected to one end of the light-emitting panel 11. The other end of the light-emitting panel 11 is electrically connected to the negative terminal of the power supply 14.

[0036] The main frame 15 also integrates a wireless charging receiver module, which is electrically connected to the circuit board 13. The function of the wireless charging receiver module is to convert received wireless energy into electrical energy signals and then transmit them to the circuit board 13. The circuit board 13 processes this electrical energy signal, performing operations such as voltage regulation and rectification, to convert it into a form of electrical energy suitable for charging the power supply 14, thereby charging the power supply 14. The power supply 14 can use a rechargeable battery, such as a lithium battery.

[0037] Visually, this product enhances the image display effect by combining the light-emitting panel 11 with the notch in the card image, making it eye-catching in different environments and creating an immersive atmosphere to improve the experience.

[0038] In terms of interaction, the light-emitting board 11 is illuminated by inserting a card into it, and the light-emitting board 11 is illuminated by rotating the trigger module 3, which reflects dynamic interaction. In terms of functionality and practicality, this utility uses three triggering methods for illuminating light: pressing, contact 23, and rotating, which are suitable for different scenarios and needs.

[0039] The selector switch 12 has multiple connection terminals. One terminal connects to the positive input line of the power supply 14, and the other two terminals connect to the contact control circuit and the rotation trigger circuit, respectively. When the selector switch 12 is switched to "contact mode", the current from the positive terminal of the power supply 14 is conducted to the relevant circuit of the contact trigger module 2; when switched to "rotation mode", the current is directed to the relevant circuit of the rotation trigger module 3, thereby realizing the switching of power supply for different triggering modes.

[0040] The main frame 15 is connected to both the contact trigger module 2 and the rotation trigger module 3.

[0041] The contact trigger module 2 includes a spring 22 and a contact 23. The main frame 15 has a slot 21. The inside of the slot 21 is fixedly connected to one end of the spring 22, and the other end of the spring 22 is fixedly connected to the contact 23.

[0042] The card engages with the card slot 21, and the card has an image notch.

[0043] The spring 22 and the contact 23 are each provided in twos and are symmetrically arranged on the front and rear sides of the slot 21.

[0044] The two contacts 23 are connected in contact. The positive terminal of the power supply 14 is electrically connected to the selector switch 12. The selector switch 12 is electrically connected to the upper contact 23. The upper contact 23 is electrically connected to the light-emitting plate 11. The light-emitting plate 11 is electrically connected to the lower contact 23. The lower contact 23 is electrically connected to the negative terminal of the power supply 14.

[0045] The first triggering method is triggered by pressing the switch 16. When the switch 16 is pressed, this independent circuit is turned on, and the current flows from the positive terminal of the power supply 14 through the switch 16 and the light-emitting board 11 back to the negative terminal of the power supply 14, and the light-emitting board 11 lights up. When the switch 16 is pressed again, the circuit is turned off and the light-emitting board 11 turns off.

[0046] The second triggering method involves the user pressing selector switch 12 to adjust the circuit to the contact 23 triggering mode.

[0047] In this series circuit, when a card is inserted into the card slot 21, the upper and lower contacts 23 make contact, which is equivalent to the positive terminal of the power supply 14 being directly connected to the negative terminal of the power supply 14 through the contact 23, forming a short circuit. The current does not pass through the light-emitting plate 11, and the light-emitting plate 11 does not light up.

[0048] When a card is inserted into the card slot 21, the card separates the upper and lower contacts 23. At this time, the current flows sequentially through the positive terminal of the power supply 14, the upper contact 23, the light-emitting plate 11, the lower contact 23, and the negative terminal of the power supply 14. The current passes through the light-emitting plate 11, and the light-emitting plate 11 lights up. The light from the light-emitting plate 11 passes through the image notch of the card, thus presenting a light with a specific image.

[0049] The rotation trigger module 3 includes a conductive disk 32, a spiral spring 33, a rotating rod 34, a contact wheel 35, and a conductive ring 36. An opening 31 is provided on the back of the main frame 15. The bottom of the opening 31 is fixedly connected to both the conductive disk 32 and the conductive ring 36. The conductive ring 36 is located outside the conductive disk 32. The conductive disk 32 is fixedly connected to one end of the spiral spring 33. The other end of the spiral spring 33 is fixedly connected to one end of the rotating rod 34. The other end of the rotating rod 34 is rotatably connected to the contact wheel 35. The contact wheel 35 is in contact with the inner wall of the conductive ring 36.

[0050] The selector switch 12 is electrically connected to the conductive disk 32, the conductive disk 32 is electrically connected to the contact wheel 35, the contact wheel 35 is electrically connected to the conductive ring 36, and the conductive ring 36 is electrically connected to the light-emitting plate 11.

[0051] The third triggering method involves the user pressing selector switch 12 to adjust the circuit to rotation triggering mode.

[0052] When the user rotates the main frame 15, a series of dynamic changes begin to occur inside the originally relatively static rotation trigger module 3;

[0053] As the rotation speed of the main frame 15 gradually increases, the centrifugal force gradually increases. Under the action of the centrifugal force, the rotating rod 34 overcomes the binding force of the spiral spring 33 and is gradually thrown outward. During the outward movement, the rotating rod 34 drives the contact wheel 35, which is rotatably connected to it, to rotate outward together. As the contact wheel 35 rotates, it gradually approaches the inner wall of the conductive ring 36. When the contact wheel 35 contacts the inner wall of the conductive ring 36, the circuit that was originally in the disconnected state is instantly connected.

[0054] At this time, the current can start from the positive terminal of the power supply 14, pass through the conductive disk 32 and the contact wheel 35, then flow to the conductive ring 36, pass through the light-emitting plate 11 and the lower contact 23, and finally return to the negative terminal of the power supply 14, forming a complete circuit, so that the current can pass smoothly through the light-emitting plate 11, thereby realizing the light-emitting plate 11 to emit light.

[0055] During this process, the vortex spring 33 plays a role in buffering and resetting. When the main frame 15 stops rotating and the centrifugal force disappears, the vortex spring 33 will gradually return to its original state, pulling the rotating rod 34 back to its initial position. The contact wheel 35 will also separate from the inner wall of the conductive ring 36, the circuit will be disconnected again, and the light-emitting plate 11 will be turned off, preparing for the next rotation to trigger the light emission.

[0056] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
