Description

Technical Field

[0001] The present application relates to the technical field of mouse pads, and particularly to a luminous mouse pad and its holographic imaging device. Background Art

[0002] With the development of technology, computer games have become a part of people's lives. A mouse pad is a pad placed under a mouse, which can provide a plane for the mouse sensor system to calculate the movement vector, facilitating the control of a computer through the mouse. Currently, there are more and more mouse pads on the market, and the types are also more diverse. Some of the mouse pads can emit light, making the mouse pad more dazzling and better meeting the atmosphere of computer games.

[0003] The opening and closing of a luminous mouse pad are mostly controlled by a lighting device installed thereon. Most of the existing lighting devices on the market have only one switch button, which is electrically connected to a single-button multi-level brightness adjustment circuit. In this way, by pressing the switch button multiple times, the functions of turning on the lighting device, adjusting the brightness of the lighting device, and turning off the lighting device can be achieved. However, in actual use, the number of times of pressing the switch button is proportional to the brightness of the lighting device. When reducing the brightness, it is often necessary to first turn off the lighting device, and then turn on the lighting device by pressing the switch button and adjust its brightness. This results in inconvenient brightness adjustment when using the lighting device. To reasonably improve this problem, the present application proposes a luminous mouse pad and its holographic imaging device. Summary of the Utility Model

[0004] The purpose of the present application is to solve the technical problem that when reducing the brightness of the existing lighting devices on the market, it is often necessary to first turn off the lighting device, and then turn on the lighting device by pressing the switch button and adjust its brightness, which results in inconvenient brightness adjustment when using the lighting device.

Detailed implementation manners

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0029] Embodiment 1

[0030] As Figures 1 - 6 shown, the luminous mouse pad proposed in Embodiment 1 of the present application includes:

[0031] A housing 1, which is formed by snap-connecting an upper half housing and a lower half housing, and a circuit board 2 is installed therein. The circuit board 2 is fixed in the housing 1 by a bolt assembly. A plurality of interfaces 3 are connected to the circuit board 2. In the present application, the number of interfaces 3 is preferably three, and the interfaces 3 can be USB interfaces 3, tap-C interfaces 3, etc., and the interfaces 3 all penetrate the outer side of the housing 1 and can be connected to an external power supply;

[0032] An LED lamp bead 4, which is connected to the circuit board 2 and is electrically connected thereto. An installation pipe 5 is installed on the circuit board 2, and the LED lamp bead 4 is arranged therein. When the LED lamp bead 4 is powered on, the light emitted by it can be emitted from one end of the installation pipe 5;

[0033] The mouse pad body 6 has a light guide tube 7 installed on its peripheral side. The shell 1 is installed on the mouse. The two ends of the light guide tube 7 are respectively plugged and matched with the opposite ends of the mounting tube 5. The plugging of the light guide tube 7 and the mounting tube 5 has the advantages of easy installation and simple disassembly.

[0034] The mounting block 8 is arranged on the circuit board 2, and a driving wheel 9 is rotatably mounted on the mounting block 8. A through slot 10 for passing the driving wheel 9 is opened on the outer side of the shell 1. The opening direction of the through slot 10 is consistent with the direction of the interface 3, and a part of the driving wheel 9 extends out of the shell 1 through the through slot 10. A resistor plate 11 is installed on the mounting block 8. The resistor plate 11 is a carbon film resistor plate, which has resistance and can pass current. A conductive block 12 is slidably matched thereon. The conductive block 12 is in sliding contact with the circuit board 2, and the conductive block 12 and the resistor plate 11 are both connected to the circuit board 2 through a wire 13. One end of the resistor plate 11 is connected to the circuit board 2, and the resistor plate 11, the conductive block 12 and the LED lamp bead 4 are connected in series in the same circuit. The conductive block 12 is connected to the driving wheel 9 through a transmission mechanism 14, and the driving wheel 9 can pass through the transmission mechanism 14. The conductive block 12 is driven to slide on the resistor plate 11. When it is away from the connection end of the resistor plate 11 and the circuit board 2, the distance that the current moves on the resistor plate 11 is longer. At this time, the resistance of the resistor plate 11 is larger, the current passing through the LED lamp bead 4 becomes smaller, the product of the power voltage and current of the LED lamp bead 4 is smaller, and the brightness of the LED lamp bead 4 is lower. After the driving wheel 9 is rotated in the opposite direction, the conductive block 12 can be driven to move toward the connection end of the resistor plate 11 and the circuit board 2. At this time, the distance that the current moves on the resistor plate 11 becomes shorter, the resistance of the resistor plate 11 becomes smaller, the current passing through the LED lamp bead 4 becomes larger, the power of the LED lamp bead 4 becomes larger, and the brightness of the LED lamp bead 4 is improved. By adopting such a design, it is convenient to adjust the brightness of the LED lamp bead 4. Compared with the prior art, it has the advantage of being easy to operate;

[0035] The fixing plate 15 is mounted on the circuit board 2, and a switch button 16 is mounted on the fixing plate 15. The switch button 16 is a prior art, and is connected in series with the LED lamp bead 4. A driving part 17 is provided on the mounting block 8, and is used to press the switch button 16. The switch button 16 can be pressed by the driving part 17, so as to turn the LED lamp bead 4 on and off.

[0036] The present application adopts a coordinated design of a through slot 10, a driving wheel 9, a resistor plate 11, a conductive block 12 and a transmission mechanism 14. The driving wheel 9 drives the conductive block 12 to slide through the transmission mechanism 14, so that the distance between the conductive block 12 and the connecting end of the resistor plate 11 and the circuit board 2 can be adjusted, thereby increasing or decreasing the resistance in the circuit of the LED lamp bead 4, so as to facilitate the adjustment of the brightness of the LED lamp bead 4. Compared with the prior art, the present application has the advantage of being easy to operate and is practical.

[0037] Embodiment 2

[0038] likeFigure 4 and Figure 5 As shown in Figure 5 , Embodiment 2 discloses a transmission mechanism 14 on the basis of Embodiment 1, where: The transmission mechanism 14 includes a mounting sleeve 1401 installed at the end of the rotating shaft of the driving wheel 9. The resistance plate 11 is arc-shaped, and the rotating shaft of the driving wheel 9 is located inside its arc and is on the same axis as the driving wheel 9. The conductive block 12 is connected to the mounting sleeve 1401. When the driving wheel 9 rotates, the conductive block 12 can be driven by the mounting sleeve 1401 to move in an arc on the resistance plate 11, so as to adjust the distance between the conductive block 12 and the connection ends of the resistance plate 11 and the circuit board 2.

[0039] Embodiment 3

[0040] As Figure 2 and Figure 3 shown in Figure 3 , Embodiment 3 of the present application is one of the embodiments of the driving part 17 in the present application. In Embodiment 3, the driving part 17 includes a guide rail 1701. The length direction of the guide rail 1701 is consistent with the opening direction of the through slot 10, and it is installed on the circuit board 2. The mounting block 8 is slidably matched with the circuit board 2, and the mounting block 8 is in active contact with the switch button 16. When the driving wheel 9 is pressed, the mounting block 8 can be pushed to slide away from the through slot 10, and then the mounting block 8 can press the switch button 16 to turn on or off the LED lamp beads 4. An elastic member 1702 is provided on the circuit board 2, which is used to drive the mounting block 8 away from the switch button 16, and the mounting block 8 can be reset by the elastic member 1702.

[0041] In Embodiment 3, the elastic member 1702 includes a compression spring, which is sleeved on the periphery of the switch button 16. Such a design can protect the compression spring and make it not easily damaged during the compression process. Its two ends are respectively in contact with the fixed plate 15 and the mounting block 8. The compression spring is used to provide a thrust force that forces the mounting block 8 to move towards the through slot 10. Under the action of this thrust force, the driving wheel 9 can extend out of the housing 1 through the through slot 10.

[0042] Embodiment 4

[0043] As Figure 4 and Figure 5 shown in Figure 5 , Embodiment 4 of the present application is another embodiment of the driving part 17 in the present application. In Embodiment 4, the driving part 17 includes a convex block 1703, which is connected to the periphery of the driving wheel 9. The fixed plate 15 is arranged on the periphery of the driving wheel 9, and the convex block 1703 is in active contact with the switch button 16. With such a design, when the conductive block 12 moves to one end of the resistance plate 11, the convex block 1703 can contact the switch button 16 and press it to turn on or off the LED lamp beads 4. Such a design has the advantages of simple structure and convenient operation.

[0044] In the fourth embodiment, an inclined surface 18 is formed on the bump 1703. The inclined surface 18 is located on the side of the bump 1703 facing the switch button 16. With such a design, it is convenient for the inclined surface 18 to come into contact with the switch button 16 during the movement process, and the maximum distance between the inclined surface 18 and the axis of the driving wheel 9 is greater than the maximum distance between the switch button 16 and the axis of the driving wheel 9. With such a design, the rotation angle of the driving wheel 9 can be restricted, so that the bump 1703 cannot pass through the switch button 16.

[0045] Embodiment Five

Through the projection device 19, the outline of a standard keyboard can be projected on the surface of the mouse pad body 6, and then the movements of the fingers are tracked by infrared technology, and finally the acquisition of input information is completed. This technology is an existing publicly disclosed technology. For example, a projection keyboard of an intelligent terminal and an operation method of the projection keyboard disclosed in Patent Publication No. CN107562205B record this technology. With such a design, the functions of the mouse pad and the keyboard can be combined into one, which can reduce the number of unnecessary devices to a certain extent and has practicality.

[0047] In the fifth embodiment, slots 20 are symmetrically arranged at intervals on the top of the housing 1. The slots 20 are inclined, and the distance between the two slots 20 gradually decreases from bottom to top. Plug plates 21 are movably inserted into the slots 20. The ends of the plug plates 21 are all formed with the housing 1. A card slot 22 is formed in cooperation with the bottom of the projection device 19. The housing 1 is inserted and matched with the card slot 22. The projection device 19 is detachably installed on the top of the housing 1 through the plug plates 21. With such a design, when not in use, it can be stored, making it not easily damaged.
