[0001] The utility model relates to the technical field of mice, in particular to a touch panel mouse. Background Art

[0002] A mouse, generally an external input device of a computer, is also an indicator for positioning the horizontal and vertical coordinates of a computer display system. The use of a mouse is to make the operation of the computer more simple and fast, replacing the cumbersome instructions of the keyboard.

[0003] As a variant of an industrial mouse, a touch panel mouse is commonly used in public, industrial and other environments. Industrial mice have the characteristics of strong durability, water and dust resistance, and high precision, and can maintain high-precision work under harsh working environments and conditions.

[0004] Most of the existing industrial mouse buttons have only one key travel, and can only work according to the predetermined functions, unable to realize button functions according to different trigger key travels, resulting in a single working effect. And most of the existing industrial equipment working procedures are cumbersome and complex. In a complete working process, multiple components often need to cooperate to work to achieve the goal. Therefore, an industrial mouse with multiple key travels and capable of realizing multiple functions according to different key travels can provide great convenience for the work of industrial equipment. Summary of the Utility Model

[0005] The utility model provides a touch panel mouse, which solves the problem of single button function.

[0006] The technical solution of the utility model is as follows:

[0007] A touch panel mouse, comprising a panel, a bottom plate, a rechargeable lithium battery, and a rechargeable battery compartment. The panel is threadedly connected to the bottom plate. A PCB circuit board is installed on the side of the bottom plate close to the panel. An embedded magnet, a cable socket, a main control chip, a power socket, and several induction modules are installed on the PCB circuit board. Each induction module includes a Hall sensor. The output end of the rechargeable battery compartment is electrically connected to the input end of the main control chip through the cable socket. A signal transmitter is provided on the main control chip. Several trigger components are provided on the side of the panel away from the bottom plate. The trigger components include a top cover and a trigger module. One end of the trigger module away from the PCB circuit board abuts against the top cover. The signal output end of the Hall sensor is electrically connected to the input end of the main control chip through the cable socket. The output end of the main control chip is electrically connected to the input end of the power socket.

[0008] Preferably, sealing gaskets are provided at the threaded fixing part of the panel and the bottom plate, the connection part of the trigger component and the panel, and the connection part of the touch panel and the panel.

[0009] Preferably, the sensing module includes a pressure sensor. A touchpad is fixedly provided on the panel. One end of the touchpad close to the PCB circuit board is electrically connected to the input end of the pressure sensor.

[0010] Preferably, the triggering module includes a base, a trigger rod, a compression spring, and a magnet. The base is fixedly connected to the PCB circuit board. The triggering end of the trigger rod abuts against the compression spring. The other end of the compression spring is fixedly connected to the top cover. The other end of the trigger rod is slidably connected to the base. The magnet is located at one end of the bottom of the trigger rod close to the Hall sensor.

[0011] Preferably, the bottom plate is provided with a plurality of fixing holes. The distribution quantities of the fixing holes on both sides of the central axis of the bottom plate are the same, and the fixing holes are symmetrically distributed along the central axis of the bottom plate.

[0012] Preferably, the pressure sensor is a strain gauge type pressure sensor.

[0013] Preferably, the Hall sensor is a HAL248G micro switch type Hall sensor.

[0014] The working principle and beneficial effects of the utility model are as follows:

[0015] The utility model provides a touchpad mouse. When the device works, the main control chip can receive the electrical signals transmitted by the sensing module through the signal transmission port and send them to the device main control end connected to this device through the signal transmitter. The device main control end can make different feedbacks according to the received electrical signals of different intensities. When the user uses this device, by pressing the triggering component, the trigger rod will bear force and move downward. During the process of the trigger rod moving downward, the magnet located at the bottom of the trigger rod will generate a magnetic field with the magnet embedded in the PCB circuit board. This magnetic field will be sensed by the magnetic field sensing element in the Hall sensor. Due to the Hall effect, a current perpendicular to the magnetic field direction will be generated on the PCB board, thereby forming a potential difference, that is, a real-time voltage, between the magnetic fields. At this time, the real-time voltage will be transmitted along the PCB circuit board to the Hall element in the Hall sensor. After receiving the real-time voltage, the Hall element will measure it and convert it into an output signal, which is transmitted to the input end of the main control chip along the output end of the Hall sensor. Since the magnitude of the voltage is proportional to the magnetic field strength, and the magnetic field strength is inversely proportional to the distance between the two magnets, when pressing the trigger rod, the real-time voltage received by the Hall element is constantly changing. Based on this, by setting different trigger voltages in the main control chip, the utility model can have multiple trigger key strokes, and each key stroke corresponds to a function, thereby realizing the multi-functional effect of this device.

[0016] The utility model solves the problem of single function of industrial mouse buttons in the prior art by setting a magnet on the trigger component and a Hall sensor on the PCB board. When the trigger component is pressed, a real-time voltage can be generated and detected and received by the Hall sensor. Due to the Hall effect, the device can provide different real-time voltages according to different pressing degrees during use. By presetting the trigger voltage thresholds corresponding to different functions on the main control chip, different functions of the utility model can be triggered by different triggering degrees.

Specific Embodiments

[0026] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present utility model clearer, the technical solutions of the present utility model will be further described below with reference to the drawings and through specific embodiments.

[0027] As Figure 1 , Figure 2 and Figure 6As shown in the figure: This embodiment provides a touchpad mouse, which includes a panel 1, a bottom plate 2, a trigger assembly 3, and a touchpad 5. The panel 1 is threadedly connected to the bottom plate 2. The panel 1 and the bottom plate 2 of this embodiment can be fixed as a whole through fixing bolts, improving the firmness of the overall structure and making it difficult for the panel 1 and the bottom plate 2 to separate. Due to the advantages of firm structure and convenient disassembly and assembly of threaded connection, the threaded connection method can also make this embodiment easy to disassemble and repair.

[0028] As Figure 3 , Figure 4 and Figure 6 shown in the figure: On the side of the panel 1 away from the bottom plate 2, there are several trigger assemblies 3 and a touchpad 5. The trigger assembly 3 includes a top cover 301 and a trigger module 302. The trigger module 302 includes a base 312, a trigger rod 322, a compression spring 332, and a magnet 342. One end of the trigger rod 322 away from the PCB circuit board 8 abuts against the top cover 301. The output end of the touchpad 5 is electrically connected to the input end of the pressure sensor 402, and the output end of the pressure sensor 402 is electrically connected to the input end of the main control chip 10 through a cable socket 9. In this design, the touchpad 5 is connected to the sensing module 4. The sensing module 4 includes a pressure sensor 402, which is a sensor that can convert pressure into an electrical signal. Through this design, the pressure applied by the user when touching or pressing the touchpad can be detected by the pressure sensor 402 and converted into an electrical signal and transmitted to the main control chip 10 through the transmission interface, and the main control chip 10 can react according to the received electrical signal.

[0029] A signal transmitter 1001 is provided on the main control chip 10. With this design, the electrical signal received by the main control chip 10 through its integrated signal transmission port can be transmitted to the device control end connected to this embodiment, facilitating the device control end to execute corresponding functions according to the electrical signal.

[0030] As Figure 1 and Figure 3 shown in the figure: Sealing gaskets 12 are provided at the threaded fixing part between the panel 1 and the bottom plate 2, the connection part between the trigger assembly 3 and the panel 1, and the connection part between the touchpad 5 and the panel 1. The sealing gasket 12 can effectively prevent impurities such as water mist or dust from entering the interior of this embodiment, achieving the effect of waterproof and dustproof, and being beneficial for this embodiment to maintain a high working safety in different working environments.

[0031] In this embodiment, the panel 1, the bottom plate 2, and the top cover 301 are all made of aluminum alloy material. The aluminum alloy material has good corrosion resistance, oxidation resistance, and heat resistance. Using the aluminum alloy material can enable this embodiment to work in a variety of harsh working environments. At the same time, the aluminum alloy also has high surface treatment performance, being easy for anodic oxidation and spraying, making this embodiment have good aesthetics while ensuring working performance.

[0032] The pressure sensor 402 used in this embodiment is a strain gauge pressure sensor, which can convert pressure into an electrical signal. This type of sensor utilizes the piezoresistive effect to measure pressure. Its surface is covered with a layer of conductive material. When pressure is applied, the resistance value of the conductive material changes. By measuring the change in the resistance value, the magnitude of the pressure applied to the sensor can be determined.

[0033] The working principle of this embodiment will be described below in conjunction with Figures 1-6 this.

[0034] Specifically, the main control chip 10 can receive the electrical signal transmitted by the induction module 4 through the signal transmission port and send it to the device main control end connected to this device through the signal transmitter 1001. The device main control end can make different feedbacks according to the received electrical signals of different intensities. When the user uses this device, by pressing the trigger assembly 3, the trigger rod 322 will move downward under pressure. During the process of the trigger rod 322 moving downward, the magnet 342 located at the bottom of the trigger rod 322 will generate a magnetic field with the embedded magnet 801 in the PCB circuit board 8. This magnetic field will be sensed by the magnetic field sensing element in the Hall sensor 401. Due to the Hall effect, a current perpendicular to the magnetic field direction will be generated on the PCB circuit board 8, thereby forming a potential difference, that is, a real-time voltage, between the magnetic fields. At this time, the real-time voltage will be transmitted along the PCB circuit board 8 to the Hall element of the Hall sensor 401. After receiving the real-time voltage, the Hall element will measure it and convert it into an output signal, which is transmitted to the input end of the main control chip 10 along the output end of the Hall sensor 401. Since the magnitude of the voltage is proportional to the magnetic field strength, and the magnetic field strength is inversely proportional to the distance between the two magnets, when pressing the trigger rod 322, the real-time voltage received by the Hall element is constantly changing. Based on this, by setting different trigger voltages in the main control chip 10, this application can have multiple trigger key strokes, and each key stroke corresponds to a function, thereby achieving the multi-functional effect of this application.

[0035] This embodiment can work with industrial equipment such as numerical control machine tools, instruments, and medical equipment as the input device of the above-mentioned equipment. As an improved part of this embodiment, when this embodiment is working, the operator can set multiple trigger key strokes through the device main control end. Taking the application of this embodiment to a ventilator as an example, the operator sets the ventilator functions corresponding to different trigger key strokes at the ventilator main control end. For example, a trigger key stroke of 0.4 mm corresponds to turning on the ventilator, a trigger key stroke of 1.5 mm corresponds to turning on the oxygen supply function, and a trigger key stroke of 2.6 mm corresponds to turning off the ventilator. When in use, those skilled in the art only need to press the same trigger module 302 with different pressures to achieve the effect of controlling the operation of the ventilator. At the same time, since the compression spring 332 is included in the trigger module 302 of this application, the compression spring 332 will automatically rebound after being pressed by the user, avoiding the problem of accidental touch.

[0036] Preferably, in this embodiment, as Figure 4 shown: The triggering end of the trigger rod 322 abuts against the compression spring 332, the other end of the compression spring 332 is fixedly connected to the top cover 301, and the magnet 342 is located at one end of the bottom of the trigger rod 322 facing the PCB circuit board 8. With such a design, it can be avoided that the compression spring 332 generates non-compressive deformation due to the deviation of the pressing angle of the user during compression, ensuring the stability of the operation of the trigger module 302.

[0037] Preferably, in this embodiment, the Hall sensor 401 is a HAL248G micro-switch type Hall sensor. The HAL248G high-sensitivity Hall chip is a non-polar Hall effect sensor based on mixed-signal CMOS technology, which has the advantages of high sensitivity and high stability, and can enable the trigger module 302 in this embodiment to still maintain high sensitivity and stability after working for a long time and multiple times.

[0038] Preferably, in this embodiment, as Figure 2 shown: The bottom plate 2 is provided with a plurality of fixing holes, the distribution quantities of the fixing holes on both sides of the central axis of the bottom plate 2 are the same, and the fixing holes are symmetrically distributed along the central axis of the bottom plate 2. With such a design, this embodiment can be fixed to the device used in combination with this embodiment by using fixing bolts to pass through the fixing holes. The fixing holes are symmetrically distributed along the central axis of the bottom plate 2, and symmetric fixing can make this embodiment more firm and not easily fall off the working device.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
