[0019] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0020] Please refer to Figures 1-12 This utility model proposes a detachable touchpad, including a mounting body 1 and a foldable touchpad module 2. The mounting body 1 is the device end, such as the external touchpad module of a laptop or desktop computer. The foldable touchpad module 2 is detachably connected to and electrically connected to the mounting body 1. The foldable touchpad module 2 includes a foldable touchpad assembly 21, a wireless connection module 22, a laser pointer assembly 23, a power control module 24, and a connection component 25. The wireless connection module 22, the laser pointer assembly 23, the power control module 24, and the connection component 25 are all fixedly connected to one side of the foldable touchpad assembly 21. The power control module 24 is electrically connected to the foldable touchpad assembly 21, the wireless connection module 22, and the laser pointer assembly 23, respectively. The power control module 24 is electrically connected to the mounting body 1, and the connection component 25 is detachably connected to the mounting body 1.

[0021] In this embodiment, the foldable touchpad module 2 is detachably connected to the mounting body 1. When the foldable touchpad module 2 is fixed to the mounting body 1 for use, the foldable touchpad assembly 21 unfolds and can be used as a mouse. At this time, the wireless connection module 22 and the laser pointer assembly 23 are disabled, and the power control module 24 does not supply power to the foldable touchpad assembly 21. The device directly supplies power to the foldable touchpad assembly 21 through the mounting body 1. When remote control of the device is required, the foldable touchpad module 2 can be detached from the mounting body 1. During use, the power control module 24 can be activated and controlled, so that the power control module 24 supplies power to the wireless connection module 22 and the foldable touchpad assembly 21, but not to the laser pointer assembly 23. The wireless connection module 22 can be a Bluetooth module or a Wi-Fi module. 2. Wireless connection is established with the device corresponding to the installation body 1. After the wireless connection is established, it can be used as a movable touchpad for remote operation. Touch operation can be performed with the touchpad away from the device. When the foldable touchpad assembly 21 is in the folded state, the function of the foldable touchpad assembly 21 is turned off. The power control module 24 supplies power to the wireless connection module 22 and the laser pointer assembly 23, so that the foldable touchpad assembly 21 can be folded for easy holding. Then, the laser pointer assembly 23 can be used to illuminate the projection area for explanation. For example, the laser pointer assembly 23 can be used to control the projection, turn PPT pages, etc., enriching the use scenarios of the touchpad. The foldable touchpad module 2 is not limited to controlling the original laptop. It can also be connected to external electronic devices with wireless connection (Bluetooth function, WiFi connection) through the wireless connection module 22, such as connecting to mobile phones, tablets, conference all-in-one screens, etc. In summary, this detachable touchpad adds functionality to the existing detachable design, making it a four-in-one touchpad with quick-release, foldable, laser pointer control, and short-range wireless connection control functions. Users can use it for multiple purposes and switch between different scenarios easily, facilitating remote operation.

[0022] In this embodiment, the power control module 24 includes a circuit board 241, a battery 242, and a power control button 243. The circuit board 241 and battery 242 are both fixedly connected to the bottom of the foldable touchpad assembly 21. The circuit board 241 is electrically connected to the foldable touchpad assembly 21, battery 242, power control button 243, wireless connection module 22, and laser pointer assembly 23. The mounting body 1 forms a contact-type electrical connection with the surface of the circuit board 241. The circuit board 241 can be a flexible circuit board embedded inside the foldable touchpad module 2, not protruding from the surface, or it can be mounted as a module embedded in the bottom of the foldable touchpad module 2. The circuit board 241 is used to distribute power to the battery 242 and can also obtain power from the mounting body 1 through contact-type electrical connection. It is also used to collect signals from the foldable touchpad assembly 21 and laser pointer assembly 23 and send them to the wireless connection module 22. The battery 242 is a lithium battery used to power the circuit board 241, foldable touchpad assembly 21, wireless connection module 22, and laser pointer assembly 23. Power is supplied via the battery 242, which can be charged through the circuit board 241. The battery 242 can be charged when the circuit board 241 is electrically connected to the mounting body 1. After the foldable touchpad module 2 is disassembled, the user can turn on or distribute power using the power control button 243. There can be one power control button 243; one button controls the power on / off, while multiple buttons control the power distribution. For example, to use the foldable touchpad assembly 21 for remote touch control, the left button of the power control button 243 is pressed; to use the laser pointer assembly 23 for remote explanation, the right button of the power control button 243 is pressed. Alternatively, the power control button 243 can be omitted, and a preset operation program can be programmed into the circuit board 241. When the foldable touchpad assembly 21 is detected as unfolded, the circuit board 241 supplies power to the foldable touchpad assembly 21; when the foldable touchpad assembly 21 is detected as folded, the circuit board 241 supplies power to the laser pointer assembly 23.

[0023] In this embodiment, the circuit board 241 is provided with an electrical contact portion 2411, which is composed of multiple conductive contacts arranged in sequence. The mounting body 1 is provided with a conductive pin portion 11, which is composed of multiple spring probes arranged in sequence. When the foldable touch panel module 2 is fixed on the mounting body 1 for use, the conductive pin portion 11 and the electrical contact portion 2411 form a contact-type electrical connection, and the device directly supplies power to the foldable touch panel module 2. At this time, the power of the battery 242 is not used, and the battery 242 is charged. The circuit board 241 is equipped with a PD fast charging protocol.

[0024] In this embodiment, the wireless connection module 22, laser pointer assembly 23, battery 242, and power control button 243 are all located on one side of the foldable touchpad assembly 21, and the circuit board 241 is located on the other side of the foldable touchpad assembly 21. When the foldable touchpad assembly 21 is folded, in order to facilitate the user's grip, the wireless connection module 22, laser pointer assembly 23, battery 242, and power control button 243 are all located on the same side.

[0025] In this embodiment, the folding touchpad assembly 21 includes a first touch module 211 and a second touch module 212. One side of the first touch module 211 is rotatably connected to one side of the second touch module 212, and an electrical connection is formed between the first touch module 211 and the second touch module 212. This ensures that the pressing function of the first touch module 211 and the second touch module 212 can be used normally when the folding touchpad module 21 is fixed on the mounting body 1 or when the folding touchpad assembly 21 is unfolded for use. Both the first touch module 211 and the second touch module 212 are electrically connected to the power control module 24. When remote touch control is required using the folding touchpad assembly 21, the first touch module 211 and the second touch module 212 are unfolded to form a planar structure, and then touch control is performed directly on either the first touch module 211 or the second touch module 212.

[0026] In this embodiment, one side of the first touch module 211 and one side of the second touch module 212 are rotatably connected via a hinge mechanism 213. The originally integrated touch module is split into two connected structures to form a foldable touchpad assembly 21, which is rotatably connected via the hinge mechanism 213. The hinge mechanism 213 allows the first touch module 211 to rotate 180° toward the touch surface (glass surface) of the second touch module 212. At the same time, an FFC (flex cable) is used to connect the first touch module 211 and the second touch module 212 in series to ensure that the touch function of the foldable touchpad assembly 21 is used normally. The switch that controls the power supply to the foldable touchpad assembly 21 is connected to the hinge mechanism 213 and electrically connected to the circuit board 241. When the first touch module 211 and the second touch module 212 are unfolded, the switch is triggered and the switch is turned on to supply power.

[0027] In this embodiment, the connecting assembly 25 includes a first connecting plate 251 and a second connecting plate 252. The first connecting plate 251 is fixedly connected to one side of the bottom of the folding touchpad assembly 21, and the second connecting plate 252 is fixedly connected to the other side of the bottom of the folding touchpad assembly 21. That is, the first connecting plate 251 is away from the second connecting plate 252. Specifically, the first connecting plate 251 is fixedly connected to one side of the first touch module 211, and the second connecting plate 252 is fixedly connected to one side of the second touch module 212. The first connecting plate 251 and the second connecting plate 252 are respectively connected to... The mounting body 1 forms a detachable connection. The first connecting plate 251 and the second connecting plate 252 can be fixedly connected to the first touch module 211 and the second touch module 212 by means of adhesive or screw fixing. In order to ensure that the folding touch panel assembly 21 can be fixed to the mounting body 1 in a flat unfolded manner, the first connecting plate 251 is set to fix the first touch module 211 and the second connecting plate 252 is set to fix the second touch module 212, so that the folding touch panel assembly 21 can be fixed by force at both ends in the flat unfolded state.

[0028] In this embodiment, the mounting body 1 is provided with an embedding groove 101, and the foldable touch panel module 2 is housed in the embedding groove 101 to reduce the external space occupied. The conductive pin part 11, the connecting part 12, and the locking part 13 are all housed in the embedding groove 101.

[0029] In this embodiment, the first connecting plate 251 is a sheet metal part, and the first connecting plate 251 is provided with a hook part 2511. The mounting body 1 is provided with a connecting part 12, and the hook part 2511 is fixedly connected to the connecting part 12. Since the hook part 2511 is located on the bottom side of the foldable touch panel module 2, during the process of installing the foldable touch panel module 2 to the mounting body 1, the hook part 2511 and the connecting part 12 are first connected to form a hook state, and then the other bottom side of the foldable touch panel module 2 is pressed towards the mounting body 1 and locked and fixed, so that the foldable touch panel module 2 is installed on the mounting body 1.

[0030] In this embodiment, the hook portion 2511 includes at least one hook 25111, and the connecting portion 12 includes the same number of slots 121 as the hooks 25111. The hooks 25111 and slots 121 correspond one-to-one and form a hook-and-loop connection, which improves the fixing effect of the foldable touchpad module 2. The hook portion 2511 also includes a plurality of limiting pins 25112, which are arranged sequentially on one side of the first connecting plate 251. The connecting portion 12 also includes a plurality of limiting grooves 122, which are arranged sequentially and distributed on the side of the embedding groove 101. On the wall, multiple limiting slots 122 correspond one-to-one with multiple limiting pins 25112. The limiting pins 25112 are housed in the limiting slots 122. When installing the foldable touchpad module 2, first align the limiting pins 25112 with the limiting slots 122 and insert them. Then, with the limiting slots 122 as the rotation center, rotate the foldable touchpad module 2 downwards so that the hooks 25111 and the slots 121 form a hook connection. The cooperation between the limiting pins 25112 and the limiting slots 122 can ensure that the foldable touchpad module 2 does not wobble in the X, Y, and Z directions, thus improving the fixation effect after installation.

[0031] In this embodiment, the second connecting plate 252 is a sheet metal part, and the second connecting plate 252 is provided with a snap-fit ​​part 2521. The mounting body 1 is provided with an elastic locking part 13. The elastic locking part 13 and the snap-fit ​​part 2521 form a locking connection, and the bottom of the elastic locking part 13 elastically abuts against the second connecting plate 252. During the process of installing the foldable touch panel module 2 to the mounting body 1, after the hook part 2511 is connected to the connecting part 12, one side of the foldable touch panel module 2 is pressed, causing the snap-fit ​​part 2521 to move down. Finally, the snap-fit ​​part 2521 and the elastic locking part 13 are aligned and locked, thereby fixing the foldable touch panel module 2.

[0032] In this embodiment, the snap-fit ​​portion 2521 includes at least one snap-fit ​​plate 25211, and the elastic locking portion 13 includes the same number of locking ends 131 as the snap-fit ​​plates 25211. Each locking end 131 corresponds to one snap-fit ​​plate 25211, and the locking ends 131 and snap-fit ​​plates 25211 form a locking connection. The snap-fit ​​plates 25211 have an L-shaped structure. Each locking end 131 includes a fixing frame 1311, a locking plate 1312, and a first elastic member 1313. The fixing frame 1311 is fixedly connected to the inner wall of the embedding groove 101. One end of the locking plate 1312 is laterally slidably connected to the fixing frame 1311. One end of the first elastic member 1313 is fixedly connected to the locking plate 1312, and the other end of the first elastic member 1313 is fixedly connected to the fixing frame 1311. 311 Abuts, the other end of the locking plate 1312 forms a locking connection with the snap-fit ​​plate 25211. The first elastic member 1313 provides an elastic thrust to the locking plate 1312 to move it to one side. When locking the snap-fit ​​plate 25211, the locking plate 1312 needs to be pried open first to slide towards the first elastic member 1313 to compress it. Then, the snap-fit ​​plate 25211 is lowered to a position aligned with the locking plate 1312. At this time, one end of the locking plate 1312 is located on one side of the snap-fit ​​plate 25211. Then, the locking plate 1312 is released, and the first elastic member 1313 returns to its original position, pushing the locking plate 1312 towards the snap-fit ​​plate 25211, finally locking the plate. The plate 25211 is laterally intercepted to form a locking connection. To ensure smoother sliding of the locking plate 1312, a sliding groove 13111 is provided on the fixing frame 1311. One end of the locking plate 1312 is received in the sliding groove 13111, and the other end of the locking plate 1312 extends out of the sliding groove 13111. The first elastic member 1313 is received in the sliding groove 13111. The elastic locking part 13 also includes at least one tensioning component 132. One end of the tensioning component 132 is fixedly connected to the bottom wall of the embedded groove 101, and the other end of the tensioning component 132 extends upward and forms an elastic abutment with the second connecting plate 252. This ensures that the foldable touchpad module 2 maintains tension when installed on the mounting body 1, avoiding... To prevent loosening, and during disassembly, the elasticity of the tensioning component 132 enables quick disassembly. The tensioning component 132 includes a second elastic element 1321 and a soft abutment plate 1322. The bottom wall of the embedded groove 101 is provided with an installation groove 1011. One end of the second elastic element 1321 is fixedly connected to the bottom wall of the installation groove 1011. One end of the soft abutment plate 1322 is fixedly connected to the other end of the second elastic element 1321. The other end of the soft abutment plate 1322 abuts against the second connecting plate 252. After the foldable touch panel module 2 is installed on the mounting body 1, the soft abutment plate 1322 abuts against the second connecting plate 252. At this time, the second elastic element 1321 is compressed, so that the foldable touch panel module 2 maintains tension and prevents loosening. The latching plate 25211 and the locking end 131 are used to cooperate, and the tensioning component 132 is used for elastic tensioning. The locking end 131 extends into the embedded groove 101 to latch the latching plate 25211, so that the foldable touchpad module 2 is fixed on the mounting body 1. The mounting body 1 can be an external touchpad module of a laptop or desktop computer. When the foldable touchpad module 2 needs to be removed, the locking plate 1312 of the locking end 131 is opened, and the tensioning component 132 acts as a pop-up device to pop up the foldable touchpad module 2, realizing the quick-release function. The detachable connection between the foldable touchpad module 2 and the mounting body 1 is not limited to the mechanical quick-release structure of the snap-fit ​​plate 25211 and the locking end 131, but can also be quick-released by magnetic attraction, screw fastening, etc.; the pop-up method after the foldable touchpad module 2 is removed is not limited to the spring pop-up of the tensioning component 132, but can also be pop-up by spring sheet pop-up, coil electromagnetic pop-up, etc., to achieve quick release.

[0033] In this embodiment, the laser pointer assembly 23 includes a laser head 231 and a control button 232. The laser head 231 is an infrared laser pointer head. Both the laser head 231 and the control button 232 are fixedly connected to one side of the foldable touchpad assembly 21. Both the laser head 231 and the control button 232 are electrically connected to the circuit board 241. The control button 232 has at least two buttons. One button of the control button 232 can control the laser head 231 to start. The other button of the control button 232 can transmit a control signal to the wireless connection module 22 through the circuit board 241. The page-turning signal is transmitted to the device through the wireless connection module 22 to realize the function of turning pages of the PPT on the screen.

[0034] Please refer to Figure 13In this embodiment, SW1 and SW2 are physical push-button switches, normally open, requiring active pressing to trigger; SW3 is a physical push-button switch, normally closed, connected to a hinge pivot, which triggers the switch when the pivot flips, opening the switch; after the electrical contact 2411 of the foldable touchpad module 2 contacts the pogopin spring probe (conductive pin 11) of the mounting body 1, pressing the SW1 physical push-button switch will cause the power management IC (charging management integrated circuit) to supply power to the wireless connection module 22 and the Touch module (foldable touchpad module 2), while simultaneously charging the battery 242, and also providing PD fast charging. The charging protocol is as follows: When the foldable touchpad module 2 is removed from the mounting body 1, the power management IC (charging management integrated circuit) is de-energized and cannot supply power to the foldable touchpad module 2 and the wireless connection module 22. The battery 242 then supplies power to the wireless connection module 22 and the foldable touchpad module 2. After the hinge is folded, SW3 is triggered, and the foldable touchpad assembly 21 is de-energized. When the SW2 switch is pressed and turned on, the battery 242 can supply power to the laser pointer module 23. The Touch module and the wireless connection module 22 are electrically connected through their respective LDO modules (low dropout linear regulators) to ensure stable power supply.

[0035] Please refer to Figure 14 In this embodiment, the Touch IC (touch management circuit) is located inside the circuit board 241. When the foldable touchpad module 2 is fixed to the mounting body 1 for use, the foldable touchpad module 2 communicates directly with the mounting body 1. For example, when the touchpad module is embedded in the PC (computer), the Touch IC (touch management circuit) communicates directly with the PC to realize the touch function. The PD PHY chip communicates directly with the PC to display the current battery level information of the battery 242. When the foldable touchpad module 2 is removed from the mounting body 1 for use, the wireless connection module 22 communicates with the mounting body 1. For example, when the touchpad module is removed and used as an independent touchpad, the Bluetooth IC (Bluetooth connection module) acts as the main control module, responsible for the communication and transmission function between the entire touchpad and the PC. The page turning function of the Touch IC (touch management circuit), the laser pointer module 23, and the information reported by the PDPHY chip are wirelessly transmitted to the PC through the Bluetooth IC (Bluetooth connection module).

[0036] In summary, this utility model combines a mechanical half-domain touch panel, a ground-side locking limit quick-release module, a hinge folding shaft structure, a wireless module, and a laser module, which enriches the functionality. Users can use one device for multiple purposes, switch between different scenarios conveniently, and facilitate remote operation.

[0037] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
