[0002] Tablet computers, also known as portable computers, are becoming more and more popular among users because of their small size and portability. In order to facilitate the input of large amounts of data, a keyboard is generally connected to the tablet computer to provide input and touch mouse control functions to improve work efficiency.

[0003] Currently, conventional keyboards can only use fingers to tap keys to achieve corresponding functions, and the key input method is single. Since some commonly used keys are far apart, it is inconvenient to constantly move the position of the fingers when tapping the keys. At the same time, moving the fingers back and forth will also affect the user's work efficiency, resulting in the inability to meet the user's growing usage needs. Utility Model Content

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] A hinge keyboard with palm rest pressure sensor keys, referring to Figure 1-3, including a keyboard body 1 and a pressure button module 2, wherein a main control board is arranged inside the keyboard body 1, and the palm rests on both sides of the keyboard body 1 are sunken to form a receiving cavity 101 adapted for the pressure button module 2; the pressure button module 2 is detachably arranged in the receiving cavity 101, and the pressure button module 2 includes an upper cover 202, a bottom cover 207 and a PCBA mainboard 204 electrically connected to the main control board, and pressure sensors 205 are integrated at the four corners of the upper surface of the PCBA mainboard 204, and the upper surface of the pressure sensor 205 is closely attached to the inner surface of the upper cover 202, so as to accurately receive the pressure of the upper cover 202 The PCBA mainboard 204 sends corresponding function instructions to the main control board according to the received pressure signal based on the pressure deformation data transmitted back. Two large pressure button modules 2 are designed at the palm rest of the keyboard, which can be pressed by the user's palm, and different functions can be set according to different pressing forces and different user needs. While using traditional fingers to tap the keys, the two pressure button modules 2 can be pressed synchronously by the palm, so as to realize multiple functions synchronously, expand the key input method, and can greatly improve work efficiency. It has advantages that current keyboards do not have and is worthy of promotion.

[0018] It should be noted that the overall principle is that when the user puts the palm of the hand in the typing position, an initial pressure will be set at the palm rest position. When the pressure button module 2 is needed during typing, as long as the palm continues to press down on the pressure button module 2, the surface of the upper cover 202 will be slightly deformed. At this time, the pressure sensor 205 will collect the deformation data and transmit it to the PCBA mainboard 204 for processing. The PCBA mainboard 204 will analyze the data and judge and confirm the function, and then send the code value of the corresponding function to the main control board. The data is transmitted to the tablet computer electrically connected to it through the main control board, so as to realize the specific function. When the user applies different pressures to the pressure button module 2 (different pressure value ranges), different functions can be realized respectively, which can be realized through software or program settings (this is an existing feasible technology and will not be explained in detail); when this button function is not used, the pressure button function can be turned off using a combination key, or other modules can be directly used to replace the position of the corresponding pressure button module 2.

[0019] In addition, a hand-holding position (not shown) may be added to one side of the accommodating cavity 101 to facilitate subsequent replacement of the pressure button module 2 .

[0020] Furthermore, a pogopin female socket 103 electrically connected to the main control board is embedded in the side of the accommodating cavity 101, and a pogopin male socket 203 compatible with the pogopin female socket 103 is integrated on the side of the PCBA mainboard 204. Through the cooperation of the pogopin male socket 203 and the pogopin female socket 103, the electrical connection between the pressure button module 2 and the keyboard body 1 can be achieved.

[0021] Furthermore, a plurality of lower adsorption parts 102 are embedded in the bottom end of the accommodating cavity 101, and an upper adsorption part 208 capable of adsorbing the lower adsorption parts 102 is correspondingly embedded in the bottom end of the bottom cover 207. Through the suction cooperation between the lower adsorption parts 102 and the upper adsorption parts 208, the pressure button module 2 can be adsorbed and fixed in the keyboard body 1.

[0022] Preferably, the upper adsorption member 208 is a magnet, the lower adsorption member 102 is an iron sheet or a magnet sheet, and there are at least one lower adsorption member 102 and at least one upper adsorption member 208 .

[0023] Furthermore, the upper cover 202 and the bottom cover 207 are combined to form an accommodation space, and the PCBA mainboard 204 is placed in the accommodation space. The four corners of the PCBA mainboard 204 are fixed in the upper cover 202 by screws 206, and the side wall of the upper cover 202 is provided with a hole 201 for the pogopin male socket 203 to extend out.

[0024] Furthermore, the upper surface of the pressure button module 2 is flush with the upper surface of the palm rest of the keyboard body 1 , which satisfies the pressure button function and does not affect the user's use experience.

[0025] To summarize, two large pressure button modules 2 are designed at the palm rest of the keyboard, which can be pressed by the user's palm, and different functions can be set according to the different pressing forces. While using traditional fingers to tap the keys, the two pressure button modules 2 can be pressed synchronously, thereby realizing multiple functions synchronously, expanding the key input method, and greatly improving work efficiency.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
