[0018] Reference Figures 1 to 3A pressure distribution detection device according to an embodiment of the present invention includes a housing 100, a support plate 200, a sensor 300, a data acquisition unit 500, and a power supply unit 400. The upper surface of the housing 100 has an opening 111. The support plate 200 is fixed within the housing 100, dividing the interior of the housing 100 into an upper cavity 201 and a lower cavity 202. A notch 210 is provided on one side of the support plate 200. The sensor 300 has a sensing area 310, and an FPC cable is provided on one side of the sensor 300. 320, sensor 300 is fixed in upper cavity 201, sensing area 310 and opening 111 are positioned correspondingly, FPC cable 320 is bent and passes through notch 210 so that FPC cable 320 is built into lower cavity 202; acquisition unit 500 is built into lower cavity 202, acquisition unit 500 is fixedly connected to FPC cable 320 so that acquisition unit 500 is electrically connected to sensor 300; power supply unit 400 is built into lower cavity 202, power supply unit 400 is electrically connected to acquisition unit 500.

[0019] In practical use, when external pressure acts on the sensing area 310 of sensor 300, sensor 300 converts the pressure signal into an electrical signal, which is transmitted to acquisition unit 500 via FPC cable 320. Acquisition unit 500 processes and converts the electrical signal, converting the analog signal into a digital signal. Power supply unit 400 provides a stable operating voltage for the entire system, ensuring the normal operation of each component. After the pressure signal is processed by acquisition unit 500, it can be output or further processed through a corresponding interface, such as a data transmission interface like Type-C or USB, for connecting to external devices and transmitting the collected pressure data to the corresponding device. In the pressure distribution detection device of this embodiment, the support plate 200 divides the housing 100 into two independent cavities, achieving a reasonable layout of sensor 300, acquisition unit 500, and power supply unit 400. The bending design of FPC cable 320 and the notch 210 passing through the structure effectively solve the signal transmission line layout problem and avoid line interference. The separation design of the upper and lower cavities 202 improves the anti-interference capability and stability of the device, while also facilitating the assembly and maintenance of the device.

[0020] In summary, the support plate 200 divides the housing 100 into two independent spaces in the vertical direction, and places the sensor 300, the acquisition unit 500, and the power supply unit 400 in the respective spaces. The sensor 300, the acquisition unit 500, and the power supply unit 400 are integrated in the housing 100, which facilitates use.

[0021] In some embodiments, refer to Figure 2 , Figure 3 and Figure 5The housing 100 includes a lower cover 120 and an upper cover 110. The lower cover 120 is spaced apart from the support plate 200 to form a lower cavity 202. The upper cover 110 covers the upper part of the lower cover 120 and is fixedly connected to it. The top surface of the upper cover 110 is spaced apart from the support plate 200 to form an upper cavity 201. The device adopts a modular design. The sensor 300 module is installed in the upper cavity 201, and the data acquisition and power supply module is installed in the lower cavity 202. During assembly, the support plate 200 is first fixed to the lower cover 120 to form the lower cavity 202. Then, the sensor 300 is installed in the upper cavity 201, and the FPC cable 320 passes through the notch 210 of the support plate 200 into the lower cavity 202. Finally, the upper cover 110 is closed on the lower cover 120 to complete the assembly of the entire device. During disassembly and maintenance, the sensor 300 can be maintained by simply opening the upper cover 110, and the data acquisition unit 500 and the power supply unit 400 can be maintained by opening the lower cover 120.

[0022] Furthermore, referring to Figure 1 The sensing area 310 is located within the opening 111, and its upper surface is lower than the upper surface of the housing 100. The housing 100 covers part of the sensor 300 to press it down and prevent it from falling. Furthermore, because the sensing area 310 is positioned lower than the upper surface of the housing 100, it is protected from direct mechanical impact damage. More preferably, the sensing area 310 is covered with a protective film (not shown in the figure). When external pressure is applied, the pressure is transmitted to the sensing area 310 through the protective film. The protective film prevents dust, moisture, grease, and other contaminants from directly contacting the sensing area 310 without affecting pressure transmission. The protective film also buffers external mechanical impacts, protecting the sensing area 310 from damage.

[0023] In some embodiments, refer to Figure 3 and Figure 4 The lower cover 120 is provided with a mounting groove 121, into which the power supply unit 400 is embedded; the acquisition unit 500 is fixedly connected to the lower cover 120. During installation, the power supply unit 400 is precisely embedded into the mounting groove 121 of the lower cover 120. The size of the mounting groove 121 matches that of the power supply unit 400, ensuring the stable fixation of the power supply unit 400. The acquisition unit 500 is tightly connected to the lower cover 120 by screws or other fixing methods. This installation method ensures the stability of each component during equipment operation and avoids loosening of connections due to vibration or other factors.

[0024] In some embodiments, refer to Figure 2 and Figure 3The lower cover 120 is provided with multiple positioning grooves 122, and the edge of the upper cover 110 is provided with multiple positioning elements 112. When the upper cover 110 is closed on the lower cover 120, the positioning elements 112 correspond one-to-one with the positioning grooves 122, and the positioning elements 112 are embedded in the positioning grooves 122. During the closing process, the positioning elements 112 on the edge of the upper cover 110 are precisely aligned with the positioning grooves 122 of the lower cover 120, and the positioning elements 112 are embedded in the positioning grooves 122 to achieve initial positioning. After positioning is completed, the upper and lower covers 120 are fixedly connected by screws or other means. The cooperation of the positioning grooves 122 and the positioning elements 112 ensures the precise fit between the upper cover 110 and the lower cover 120, avoiding offset and misalignment during the closing process.

[0025] Furthermore, referring to Figure 2 and Figure 3 The support plate 200 has multiple connecting posts 220 on the side facing the lower cover 120. Each connecting post 220 has a threaded hole 221, and the lower cover 120 has multiple through holes 123. The end of the connecting post 220 abuts against the inner bottom surface of the lower cover 120, and the threaded holes 221 and through holes 123 correspond one-to-one. Fastening screws (not shown in the figure) are connected to the threaded holes 221 and through holes 123. When installing the support plate 200, the end of the connecting post 220 is tightly abutted against the inner bottom surface of the lower cover 120 to ensure the levelness and stability of the support plate 200. Then, the fastening screws are passed through the through holes 123 of the lower cover 120 and threaded into the threaded holes 221 of the connecting posts 220. By evenly tightening each screw, a firm and reliable connection between the support plate 200 and the lower cover 120 is ensured. This achieves a rigid connection between the support plate 200 and the lower cover 120, and the distribution of multiple connection points ensures uniform stress distribution, improving the overall structural strength.

[0026] Preferably, refer to Figure 2 and Figure 3 In order to improve the structural strength and rigidity of the lower cover 120, the inner bottom surface of the lower cover 120 is provided with crisscrossing reinforcing ribs 124.

[0027] For those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the scope of protection of this utility model.
