Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliance accessories, in particular to a universal adaptable pointing stick module. Background Art

[0002] Pointing stick input devices are widely used as embedded mice in laptop computers. Furthermore, with the development of electronic devices, pointing stick input devices, due to their sensitivity and 360-degree directional sensing, are also gradually being used in industrial button mice, directional control sticks for game remote controls, directional control sticks for drones, and remote controls for televisions.

[0003] As the application types of pointing stick modules become increasingly widespread, the height requirements of their pressure transmission parts will also change with different application devices. For example, in mechanical keyboards, due to the different heights of the keycaps, different mechanical keyboard models require different heights of pressure transmission parts. If a fixed-length pressure transmission part is customized for each different product, the cost of the pointing stick module will increase, the time required for supply will increase, and the needs of customers with small batches will not be met. In addition, some applications have special external structures, which require special mechanical structures to transmit pressure to the pressure transmission parts. However, the existing pressure transmission parts are not very convenient to connect with these special mechanical structures, resulting in poor application effects. In order to adapt to these customers' applications where the transmission part design is not fixed, the pointing stick module needs to make corresponding mechanical changes to improve the adaptability and reliability of the module.

[0023] In order to enable those skilled in the art to better understand the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and implementation methods.

[0024] like Figures 1-7 The illustrated universally adaptable pointing stick module comprises a base plate 1, a sensor module 2 disposed on the base plate 1, a conductive base 3 disposed on the sensor module 2, and a conductive member 4 threadedly connected to the conductive base 3. The sensor module 2 comprises a conventional body, including a sensor substrate 21 having a mounting hole 22 defined at its center. A protrusion 31 is provided at the bottom of the conductive base 3, which mates with and plugs into the mounting hole 22. The protrusion 31 is coaxial with the conductive base 3 and is preferably integrally formed with the conductive base 3. The conductive base 3 and the sensor substrate 21 are secured with an adhesive. The mounting hole 22 and the protrusion 31 provide a snap-fit ​​mechanism that allows the force applied to the conductive base 3 and the sensor substrate 21 to be varied. When the conductive member 4 is subjected to force, the stability of the connection between the conductive base 3 and the sensor substrate 21 is achieved through the combined force of the adhesive and the support of the snap-fit ​​mechanism.

[0025] A first threaded hole 32 is coaxially defined at the top of the conductive base 3. A first threaded post 41 is provided at the bottom of the conductive member 4, which mates with and is threadedly connected to the first threaded hole 32. This threaded connection allows users to select a conductive member 4 that matches their desired height and screw it onto the conductive base 3, resulting in a highly adaptable pointing stick module with a stable and reliable structure and excellent performance. Alternatively, a second threaded post 35 is provided at the top of the conductive base 3, and a second threaded hole 36 is provided at the bottom of the conductive member 4, which mates with and is threadedly connected to the second threaded post 35.

[0026] As a preferred embodiment, the top of the conductive member 4 is provided with a mounting slot 44, which allows for the installation of a rubber cap or other additional components. The base plate 1 is provided with fixing plates 11 on both sides. The fixing plates 11 are higher than the base plate 1, forming a recessed portion between the base plate 1 and the fixing plates 11. The sensor module 2 is disposed within this recessed portion and is fixedly connected to the base plate 1 via screws. After the sensor module 2 is installed, the top surface of the sensor module 2 is substantially flush with the top surface of the fixing plate 11. The fixing plate 11 is provided with fixing holes 13. Thickened portions 14 are provided on its underside, corresponding to the fixing holes 13. The fixing holes 13 extend through the corresponding thickened portions 14. The thickened portions 14 ensure structural stability at the fixing holes 13 while allowing the fixing plate 11 to be appropriately thinned, reducing material costs. A control circuit board 5 is provided on one side of the base plate 1. The control circuit board 5 is electrically connected to the sensor module 2. The control circuit board 5 and the sensor module 2 can be designed as two independent PCB circuit boards, which are subsequently connected by welding or wire connection. A data interface is set on the control circuit board 5, which is used to connect the button-type pointing stick module with other modules.

[0027] During use, the force exerted by the user pushing on the conductive member 4 is transmitted to the conductive base 3. This force causes the sensor substrate 21 to deform, which in turn acts on the four sensing resistors (X+, X-, Y+, and Y-) fixed to its bottom surface. The force vector acting in the X direction is sensed by the X+ and X- sensing resistors, causing changes in the X+ and X- resistances. The force vector acting in the Y direction is sensed by the Y+ and Y- sensing resistors, causing changes in the Y+ and Y- resistances. The control circuitry on the control circuit board 5 performs electrical sampling, filtering, motion algorithms, and host communication functions for the changes in the resistance values ​​of the four sensor resistors (X+, X-, Y+, and Y-).

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
