Description

Technical Field

[0001] This utility model relates to the field of notebook structural design, and in particular to a planar connection device for a notebook touchpad. Background Technology

[0002] A computer touchpad, also known as a mousepad, is an input device on a laptop computer used to replace the mouse. It allows users to control cursor movement, click, and perform various multi-finger gestures, such as zooming, scrolling, and switching applications, by sliding and tapping their fingers. Touchpads are designed to provide portability and convenience for users operating their laptops without a mouse. Touchpads typically use capacitive sensing technology to detect finger movement. When a user's finger touches the touchpad surface, it causes a change in capacitance. Sensors inside the touchpad detect these changes and convert them into coordinate signals, thereby controlling cursor movement. Modern touchpads may also incorporate pressure-sensing technology, allowing users to perform additional functions by applying different levels of pressure.

[0003] However, existing touchpads often encounter the following problems during use:

[0004] (1) Traditional touchpad installation usually requires the use of screws and other fasteners, which makes the installation process cumbersome and requires specific tools and certain manual skills. Moreover, if the touchpad malfunctions, the traditional installation method may require completely disassembling the keyboard or other components to access the touchpad, which is not only time-consuming but also increases the complexity of repair.

[0045] like Figure 1-3 As shown, a planar connection device for a laptop touchpad includes: a keyboard housing 1, a screen hinge 2, a motherboard mounting housing 3, a touchpad mounting slot 4, a touchpad 5, a planar connection device 6, a magnetometer 7, and a battery 8. The screen hinge 2 is mounted on the top of the keyboard housing 1. The screen hinge 2 not only serves as the mechanical connection between the screen and the keyboard housing 1 but also cleverly integrates a magnet. This design allows the screen's flipping motion to trigger the magnetometer 7, thereby automatically cutting off power and ensuring safety when replacing the touchpad 5. The motherboard mounting housing 3 is embedded within the voice keyboard housing 1. The touchpad mounting slot 4 is formed on the keyboard housing 1, and the touchpad 5 is positioned on the touchpad mounting slot 4, with the touchpad 5 fitting snugly against the touchpad mounting slot 4. This snug fit between the touchpad 5 and the touchpad mounting slot 4 on the keyboard housing 1 ensures the stability and positioning accuracy of the touchpad 5. This design allows the touchpad 5 to precisely connect with the keyboard housing 1, providing a good user experience. Two sets of planar connection devices 6 are provided. The two sets of planar connection devices 6 are located at the connection between the touch panel 5 and the motherboard mounting shell 3. The magnetic sensor 7 is located on one side of the touch panel 5 and is electrically connected to the touch panel 5. The battery 8 is electrically connected to the magnetic sensor 7.

[0046] In this embodiment, as Figure 3-4As shown, the planar connection device 6 includes: a first connection housing 61 mounted on the touch panel 5; a first sliding groove 62 formed on the side arc surface of the first connection housing 61; a first arc-shaped groove 63 formed on the first connection housing 61; a first connecting block 64 placed in the first arc-shaped groove 63 and embedded in the opening of the first arc-shaped groove 63; one end of a first paddle 65 embedded in the first sliding groove 62 and connected to the first connecting block 64; a second connection housing 66 mounted on the motherboard mounting housing 3 and positioned corresponding to the first connection housing 61; a second sliding groove 67 formed on the second connection housing 66; a second arc-shaped groove 68 facing the opening of the first arc-shaped groove 63; a second connecting block 69 placed in the second arc-shaped groove 68; one end of a second paddle 610 embedded in the second sliding groove 67; and one end of the first paddle 65 and the second paddle 610 aligned in a straight line. Both the first connecting block 64 and the second connecting block 69 are arc-shaped. The first arc-shaped groove 63 and the second arc-shaped groove 68 are the same size. The second connecting block 69 and the groove opening of the second arc-shaped groove 68 are slidably connected. One end of the second lever 610 is connected to the second connecting block 69. The first connecting housing 61 and the second connecting housing 66 achieve quick connection and disassembly of the touchpad 5 and the motherboard mounting shell 3 through the linkage of the first lever 65 and the second lever 610, and the sliding engagement of the first connecting block 64 and the second connecting block 69. This design avoids the cumbersome traditional screw fixing method and greatly improves the efficiency of replacing the touchpad 5.

[0047] Preferably, a magnet is installed on the screen hinge 2. A magnetometer 7 can sense changes in the magnetic field of the magnet and cut off the power supply to the battery 8 accordingly. This design eliminates the need for manual power disconnection when replacing the touchpad 5, improving operational safety and avoiding the risk of accidental electric shock or circuit damage.

[0048] It should be noted that, in the case of the laptop touchpad planar connection device designed in this utility model, when it is necessary to replace the touchpad 5, first close the laptop screen cover. During the process of flipping the screen cover, the screen hinge 2 will also be rotated. When the screen hinge 2 is rotated, the magnet installed on the screen hinge 2 will also be rotated. After the magnet is rotated to the extension direction of the magnetic sensor 7, it will change the surrounding magnetic field. The magnetic sensor 7 will sense the magnetic field and thus cut off the power supply of the battery 8. At this time, it is not necessary to manually cut off the power when opening the computer back cover to replace the touchpad 5. When installing the touchpad 5, place it into the touchpad mounting slot 4 and manually move the first lever 65 and the second lever 610. The rotation of the first lever 65 and the second lever 610 will drive the first connecting block 64 and the second connecting block 69 connected to each other. Since the first arc-shaped groove 63 and the second arc-shaped groove 68 are the same size, the opening of the first connecting block 64 in the first arc-shaped groove 63 is also the same as the opening of the second connecting block 69 in the second arc-shaped groove 68. Once one end of the first connecting block 64 slides into the second arc-shaped groove 68 and one end of the second connecting block 69 slides into the opening of the first arc-shaped groove 63, the touchpad 5 is connected to the motherboard mounting shell 3, which is simple and quick.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
