Description

Technical Field

[0001] This utility model relates to the field of pressure sensor technology, specifically a high-precision flexible pressure sensor. Background Technology

[0002] The working principle of flexible pressure sensors is typically achieved by utilizing the sensing properties of deformable materials. When external pressure is applied to the sensor, the size and shape of the deformable material change, resulting in different physical parameters. These physical parameters can be measured and converted by circuitry to obtain information about the external pressure. This information can be used to monitor the user's movement and health status, to monitor the real-time contact between medical devices and the patient's body to improve surgical quality, and also for intelligent control in clinics or wards.

[0003] A search revealed a high-precision flexible pressure sensor, disclosed in publication number (CN219371534U). The sensor includes a thin-film flexible pressure sensor body, a base on which a connecting line is mounted, and a sensing circuit on which a fixed seat is fixedly installed on one side of the base. A first clamping plate is fixedly installed on the fixed seat, with the top inner wall of the first clamping plate fitting against the bottom outer wall of the connecting line. Multiple vertical plates are fixedly installed on the top side of the fixed seat, each with a groove. A lifting frame is movably mounted on the grooves. A second clamping plate is fixedly installed on the bottom side of the lifting frame, with the bottom inner wall of the second clamping plate fitting against the top outer wall of the connecting line.

[0004] The implementation of this technical solution has at least the following drawbacks: Although the utility model can limit the connecting lines, since connectors are usually used to fix the ends of the connecting lines, the connecting lines and connectors will bend during each pressure application process of the flexible pressure sensor. Prolonged bending and deformation can lead to breakage at the contact ends, necessitating improvement. Therefore, we propose a high-precision flexible pressure sensor. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision flexible pressure sensor, which solves the problem mentioned in the background art that, since connectors are usually used to fix the ends of the two connecting lines, the connecting lines and connectors will bend during each pressure process of the flexible pressure sensor, and the contact end will break due to long-term bending deformation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-precision flexible pressure sensor, comprising a flexible pressure sensor body, a connecting line connected to one side input end of the flexible pressure sensor body, auxiliary frames provided at both the upper and lower ends of one side of the flexible pressure sensor body, the front side of the auxiliary frame being arc-shaped, and a transverse reinforcing rod fixedly installed on the inner side of the auxiliary frame, a longitudinal reinforcing rod fixedly installed at one front end of the transverse reinforcing rod, and the longitudinal reinforcing rod being located on the front side of the connecting line.

[0007] By adopting the above technical solution, the connection points of the connecting wires and connectors can be limited by the auxiliary frame, thereby reducing the occurrence of bending of the connecting wires and connectors. In addition, the longitudinal reinforcing rod installed in conjunction with the transverse reinforcing rod can prevent the connectors from overlapping, thus ensuring the stability of data transmission of the flexible pressure sensor body. Furthermore, the multiple positioning holes on the auxiliary frame, through which fixing bolts pass, can limit the position of the auxiliary frame, thereby enabling rapid installation of the flexible pressure sensor body and ensuring the accuracy of the detection by the flexible pressure sensor body.

[0008] Optionally, the longitudinal reinforcing rod is inclinedly installed on its inner side, and the inclined braces are symmetrically arranged.

[0009] By adopting the above technical solution and setting the diagonal brace, the structural strength of the longitudinal reinforcing rod can be increased, the deformation of the longitudinal reinforcing rod can be reduced, and the stability of the connecting lines and connectors on the flexible pressure sensor body can be guaranteed.

[0010] Optionally, the front side of the auxiliary frame is provided with multiple positioning holes, and the positioning holes are evenly distributed between each other.

[0011] By adopting the above technical solution and setting the positioning hole, the installation of the auxiliary frame can be limited, thereby limiting the position of the flexible pressure sensor body.

[0012] Optionally, the lower end of the auxiliary frame is fixedly welded to the outer side of the flexible pressure sensor body using a welding head.

[0013] By adopting the above technical solution and setting the welding head, the stability of the connection between the auxiliary frame and the flexible pressure sensor body can be ensured. Furthermore, the auxiliary frame can constrain and limit the connectors and connecting wires on the flexible pressure sensor body, thereby ensuring the accuracy of the flexible pressure sensor body.

[0014] Optionally, the other end of the connecting line is provided with a connector, and the connectors are arranged symmetrically.

[0015] By adopting the above technical solution and setting the connector, the output end of the flexible pressure sensor body can be connected to the connecting line, thereby enabling data transmission.

[0016] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0017] This application's technical solution, through the design of a flexible pressure sensor body, connector, auxiliary frame, transverse reinforcing rod, longitudinal reinforcing rod, and positioning holes, not only limits the connection points of the connecting wires and connectors through the auxiliary frame, thereby reducing the likelihood of bending, but also, in conjunction with the longitudinal reinforcing rod installed longitudinally along the transverse reinforcing rod, prevents the connectors from overlapping, thus ensuring the stability of data transmission from the flexible pressure sensor body. Furthermore, the multiple positioning holes on the auxiliary frame, through which fixing bolts pass, limit the position of the auxiliary frame, thereby enabling rapid and precise installation of the flexible pressure sensor body and ensuring the accuracy of the sensor's detection.

[0022] Please see Figure 1-2This utility model provides a technical solution: a high-precision flexible pressure sensor, including a flexible pressure sensor body 1. A connecting line 11 is connected to the input end of one side of the flexible pressure sensor body 1. Auxiliary frames 2 are provided at both the upper and lower ends of one side of the flexible pressure sensor body 1. The front side of the auxiliary frame 2 is arc-shaped, and a transverse reinforcing rod 22 is fixedly installed on the inner side of the auxiliary frame 2. A longitudinal reinforcing rod 23 is fixedly installed at one end of the front side of the transverse reinforcing rod 22, and the longitudinal reinforcing rod 23 is located in front of the connecting line 11. The lower end of the auxiliary frame 2 is fixedly welded to the outer side of the flexible pressure sensor body 1 through a welding head 21. The welding head 21 ensures the stability of the connection between the auxiliary frame 2 and the flexible pressure sensor body 1. Furthermore, the auxiliary frame 2 can constrain and limit the connecting head 12 and the connecting line 11 on the flexible pressure sensor body 1, thereby ensuring the accuracy of the flexible pressure sensor body 1. A connecting head 12 is provided at the other end of the connecting line 11. The connecting heads 12 are symmetrically arranged, allowing the output end of the flexible pressure sensor body 1 to be connected to the connecting line 11 for data transmission.

[0023] An inclined brace 24 is installed on the inner side of the longitudinal reinforcing rod 23, and the inclined brace 24 is symmetrically arranged. By setting the inclined brace 24, the structural strength of the longitudinal reinforcing rod 23 can be increased, the deformation of the longitudinal reinforcing rod 23 can be reduced, and the stability of the connecting line 11 and the connector 12 on the flexible pressure sensor body 1 can be guaranteed.

[0024] The front side of the auxiliary frame 2 is provided with multiple positioning holes 3, which are equidistant from each other. The positioning holes 3 can be used to limit the installation of the auxiliary frame 2, thereby limiting the position of the flexible pressure sensor body 1.

[0025] The auxiliary frame 2 limits the connection points of the connecting wires 11 and 12, thereby reducing the likelihood of bending. The auxiliary frame 2, in conjunction with the transverse reinforcing rod 22, further strengthens the auxiliary frame 2 laterally, reducing deformation. The longitudinal reinforcing rod 23, installed along the transverse reinforcing rod 22, prevents the 12 connectors from overlapping, ensuring the stability of data transmission from the flexible pressure sensor body 1. Simultaneously, the auxiliary frame 2 has multiple positioning holes 3, through which fixing bolts penetrate, limiting its position and facilitating rapid installation of the flexible pressure sensor body 1, thus ensuring the accuracy of its detection.
