DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 - 5, the present utility model discloses a palm-sized card computer device, including a bottom case 1. Between the upper surfaces of the peripheral side walls of the bottom case 1, a first circuit board 2 is installed. Near the front side of the lower surface of the first circuit board 2, a storage battery 3 is installed. The supply voltage of the storage battery 3 is 5V, supporting 4.2V battery power supply and USB 5V power supply. At the rear side position of the lower surface of the first circuit board 2, a cover plate 4 is installed. Inside the cover plate 4, a second circuit board 5 is installed. On the rear side edge of the upper surface of the first circuit board 2, a main control socket assembly 6, a first toggle switch 7, an SD card slot 8, a display screen assembly 9, and an infrared communication module 10 are installed in sequence from right to left. On the upper surface of the main control socket assembly 6, a main controller 11 is inserted. The main controller 11 uses an ESP32S3 chip which integrates 2.4G WiFi and 2.4G Bluetooth inside. There is no need to connect a communication chip outside the MCU. Both 2.4G WiFi and 2.4G Bluetooth are integrated into the SoC internal, simplifying the development process and hardware cost. Integrating 2.4G WiFi and 2.4G Bluetooth into the SoC internal has good signal strength stability, enabling it to be competent for various wireless application scenarios and making the communication connection more stable and reliable. When Bluetooth and WiFi communicate outside the MCU, there will be relatively large radiation interference. The radiation interference will reduce the communication propagation distance and cause communication anomalies during communication, etc. Users can add their own project codes to the existing projects of the FLASH version chip to develop their own firmware and make differentiated products. Relatively speaking, it has higher flexibility. Users can use this device to develop and control terminals to achieve smart home development. The infrared communication module 10 is an IRDA communication module. On the right side position of the upper surface of the main controller 11, a USB interface 12 is installed. On the lower surface of the main controller 11, a buzzer 13 is installed. The main controller 11 can be used for voice recognition and voice control functions. The function of the buzzer 13 can be used as a confirmation and return prompt instruction. On the left side edge of the upper surface of the first circuit board 2, a second toggle switch 14 is fixedly installed. At the front side position of the upper surface of the first circuit board 2, a key assembly 15 is provided. The key assembly 15 uses a 52-key keyboard. This kind of keyboard design is usually to adapt to the portability and usability of palm-sized devices while maintaining a sufficient number of keys to meet basic input needs. On the upper surface of the bottom case 1, a face case 16 is installed.

[0021] Specifically, on the upper surfaces of the left and right side walls of the bottom case 1 and the lower surfaces of the front and rear side walls of the face case 16, limit blocks 17 are provided. On the corresponding first circuit board 2, limit slots 18 are opened. The limit blocks 17 are inserted into the limit slots 18.

[0022] In this implementation scheme, the limit blocks 17 on the bottom case 1 and the face case 16 are inserted into the limit slots 18 on the first circuit board 2, making the installation position of the first circuit board 2 more accurate.

[0023] Specifically, a protective cover 19 is installed on the upper surface of the main controller 11.

[0024] In this embodiment, the protective cover 19 is used to protect the upper surface of the main controller 11 to prevent it from being damaged.

[0025] Specifically, first through holes 20 are respectively formed in the rear side wall of the front shell 16 at positions corresponding to the first toggle switch 7, the SD card slot 8, and the infrared communication module 10, and the first toggle switch 7, the SD card slot 8, and the infrared communication module 10 all protrude from the rear side of the rear side wall of the front shell 16.

[0026] In this embodiment, the first through holes 20 enable the first toggle switch 7, the SD card slot 8, and the infrared communication module 10 to protrude from the front shell 16, facilitating the use of the first toggle switch 7, the SD card slot 8, and the infrared communication module 10.

[0027] Specifically, a second through hole 21 is formed in the left side wall of the front shell 16 at a position corresponding to the second toggle switch 14, and the second toggle switch 14 protrudes from the outer side of the left side wall of the front shell 16.

[0028] In this embodiment, the second through hole 21 enables the second toggle switch 14 to protrude from the left side wall of the front shell 16, facilitating the operation of the second toggle switch 14.

[0029] Specifically, third through holes 22 are respectively formed in the upper surface of the front shell 16 at positions corresponding to the main controller 11, the display screen assembly 9, and the button assembly 15, and the button assembly 15 protrudes from the upper side of the upper side wall of the front shell 16.

[0030] In this embodiment, the third through holes 22 enable the main controller 11, the display screen assembly 9, and the button assembly 15 to protrude from the upper side wall of the front shell 16, facilitating the insertion of the USB interface 12 on the main controller 11, facilitating the viewing of information on the display screen assembly 9, and facilitating the pressing and use of the button assembly 15.

[0031] When in use, the main controller 11 has Bluetooth and WiFi communication functions, and the infrared communication module 10 uses IRDA communication. There are more interconnection methods. Whether it is Bluetooth communication, WiFi communication or IRDA communication, an appropriate communication connection method can be selected according to the communication distance, or communication can be selected according to the power consumption level. When selecting file transfer according to different transmission rates, the handheld card computer is default to demo when leaving the factory. The handheld card computer has a display screen function, and the screen displays basic function initialization. Users need to compile according to their own needs to achieve the expected ideal state. The function status can be viewed through the screen display. The product buttons are equipped with button prompts. Press the buttons to select functions. Press the button to switch the function interface and enter the confirmation interface. Press the RES button to return to the main menu interface. Users can set the button functions according to their own needs. The main controller 11 has a built-in storage function. By cooperating with the button component 15 and the display screen component 9 through the main controller 11, users can compile according to their own needs to achieve the expected ideal state. The function status can be viewed through the screen display. The product buttons are equipped with button prompts. Press the buttons to select functions, switch the function interface, press the button to enter the confirmation interface, and press the RES button to return to the main menu interface. Users can set the button functions according to their own needs, and develop their own project codes and firmware through the main controller 11. It has higher flexibility in use. By adding an SD card through the SD slot 8 to expand the storage, it has the advantages of simple structure, convenient operation, flexible operation, etc., and is easy to carry and can be widely used in various scenarios, and better realizes the purpose of the man-machine interaction work.
