[0038] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0039] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity and not intended to limit the scope of implementation. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0040] This application discloses a handheld data detection device for a driving recorder, comprising an upper housing assembly, an integrated circuit board assembly, and a lower housing. The spatial relationship among these three components is as follows: the integrated circuit board assembly is located below the upper housing assembly, and the lower housing is located below the integrated circuit board assembly.

[0041] The integrated circuit board assembly includes a circuit integrated board 24, and a display screen 25 is attached to the front top of the circuit integrated board 24. The display screen 25 is built into a protective frame 29, and the height of the protective frame 29 is slightly higher than the height of the display screen 25, so that the display screen 25 is fully protected.

[0042] The circuit board 24 includes a security chip 21, several modules 22, and a microcontroller unit 23. The security chip 21 is mounted on the back of the circuit board 24 and is electrically connected to the microcontroller unit 23, while the modules 22 and the microcontroller unit 23 are mounted on the front of the circuit board 24 and are also electrically connected. More specifically, the front of the circuit board 24, from top to bottom, has a display screen 25, modules 22, and microcontroller unit 23 arranged sequentially.

[0043] The circuit board 24 has a storage unit 27 and an identification unit 28 symmetrically arranged on the bottom back. The identification unit 28 provides network access services for the device, and the storage unit 27 stores the data from the driving recorder. When the identification unit 28 provides network access services for the device, the device operates normally. The top of the circuit board 24 has an interface 26, through which the device connects to the driving recorder for data transmission.

[0044] During data detection, the microcontroller unit 23 calculates the data, while the security chip 21 checks the calculated data. If the data is found to have been tampered with or lost, an error will be reported on the display screen 25.

[0045] The bottom edge of the protective frame 29 has an opening in the middle, through which the ribbon cable 251, which is electrically connected to the display screen 25, passes. The ribbon cable 251 is electrically connected to the module 22. Therefore, during human-machine interaction, after the module 22 executes the command, the display screen 25 displays the execution result.

[0046] The upper housing assembly includes a first mounting plate 12, which has mounting holes 13 for mounting a plurality of buttons 11. Support posts are connected to the back of each button 11, passing through the mounting holes 13 and abutting against the circuit board 24. The height of the support posts is not less than the height of the protective frame 29, thus providing a second layer of protection for the display screen 25. The first mounting plate 12 also has a slot for exposing the display screen 25, and a display screen protection plate 14 is tightly fitted onto the slot, providing a third layer of protection for the display screen 25. Furthermore, each button 11 corresponds to a module 22, and the buttons 11 are close to the display screen protection plate 14. This design allows operators to simultaneously focus on the display screen 25 and the buttons 11 while operating the equipment, without needing to deviate too far from the screen, thus improving equipment efficiency.

[0047] The upper housing assembly also includes an upper housing edging 15, which is set along the edge of the first mounting plate 12 to cover the first mounting plate 12 and protect it. The upper housing edging 15 and the lower housing together form the equipment housing. The middle part of the equipment housing is a grip area, characterized by its width being smaller than the width of the upper part of the equipment housing. This design creates a comfortable handhold area in the middle of the equipment housing, and the button 11 is located in the upper center of the grip area, making it more convenient for operators to use.

[0048] A rechargeable battery assembly 4 is installed inside the lower housing. The rechargeable battery assembly 4 is located below the integrated circuit board assembly, more specifically, below the integrated circuit board 24. The rechargeable battery assembly 4 includes a rechargeable battery 41, a wireless charging module 42, and a wave-absorbing part 43 located between the two. The wireless charging module 42 charges the rechargeable battery 41, and the wave-absorbing part 43 reduces electromagnetic interference received by the wireless charging module 42. The charging interface of the rechargeable battery assembly 4 is interface 26.

[0049] To prevent the rechargeable battery assembly 4 from falling off, the lower housing is also provided with a limiting part, which includes a first limiting part 31 and a second limiting part 32. The first limiting part 31 is located at the four corners of the rechargeable battery assembly 4, and the second limiting part 32 is located on the side of the rechargeable battery assembly 4.

[0050] The two first limiting parts 31 located at the bottom of the lower shell can also serve as pillars, and together with the two pillars at the top of the lower shell, they provide support for the upper shell edging 15.

[0051] The lower housing also has wireless and Bluetooth slots, which are used to insert Bluetooth module 5 and wireless module 6 respectively. When the transmission interface of an individual driving recorder is not compatible with the interface 26 of this device, Bluetooth module 5 and wireless module 6 can be used to transmit the storage data of the driving recorder to the device.

[0052] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
