Technical Field

[0001] This application relates to the field of foot detection equipment, and more particularly to an assembly structure for a pressure plate. Background Technology

[0002] Currently, foot pressure testing equipment is widely used in medical rehabilitation, sports science, and commercial fields, primarily for gait analysis, foot health assessment, and custom insoles. Traditional pressure plates often employ an integrated design, with sensors tightly integrated into the load-bearing structure. While this achieves basic functions, it suffers from significant shortcomings in maintainability, durability, and ease of production. With the increasing popularity of modular design concepts, the market demand for pressure plates that are quick to maintain, highly accurate, and cost-effective is growing.

[0003] In existing technologies, common solutions include integrated pressure plates, where the sensor is separately bonded to the load-bearing panel and base plate. The advantage is simple structure, but maintenance requires replacement of the entire plate, resulting in high costs. Embedded circuit layouts expose the wiring beneath the load-bearing surface, making it susceptible to damage under long-term pressure. These solutions involve compromises in stability, maintenance efficiency, and production costs. Maintenance is difficult; sensor damage necessitates replacement of the entire board; and the circuit wiring lacks protection, resulting in poor durability. Utility Model Content

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] This application discloses an assembly structure for a pressure plate, see [link to relevant documentation]. Figures 1 to 3 The device includes a rectangular housing 1, a pressure element 2 for measuring pressure, and a load-bearing element 3 for stabilizing overall deformation. The load-bearing element 3 is connected to the housing 1 and located below the housing 1. The pressure element 2 is connected to both the load-bearing element 3 and the housing 1, and is located between the load-bearing element 3 and the housing 1. The housing 1 has a measuring part 12 and a receiving part 11 for accommodating wires. The test end 22 of the pressure element 2 is connected to the measuring part 12, and the pressure element 2 has a signal transmission wire 23, which is installed inside the receiving part 11.

[0026] Specifically, see Figure 1 and Figure 2 The pressure component 2 includes a pressure sensor module 21, and the test end 22 includes a pressure-sensitive element board, which is laid on the pressure sensor module 21. The signal transmission cable 23 is electrically connected to the pressure sensor module 21 and is laid inside the receiving part 11.

[0027] In one embodiment, the measuring part 12 includes a test channel formed on the housing 1, which provides a test passage to the pressure-sensitive element plate, facilitating the tester to place both feet on the pressure-sensitive element plate to test foot pressure and obtain a foot pressure distribution map. The receiving part 11 includes a receiving chamber formed on the bottom surface of the housing 1, and the receiving chamber is rectangular in shape. The signal transmission line 23 is laid along the receiving chamber and then extends out of the housing 1.

[0028] Specifically, see Figure 2 and Figure 3 The load-bearing component 3 has a pressure positioning part 32, and the pressure component 2 has a first positioning part 24. The pressure component 2 and the load-bearing component 3 are connected by a first connecting part 4. The first connecting part 4 passes through the first positioning part 24 and then enters the pressure positioning part 32, and is rotatably connected to the pressure positioning part 32.

[0029] In one embodiment, the load-bearing component 3 includes a load-bearing plate 31, which is used to enhance the overall structural support, stabilize the overall deformation, and maintain flatness and non-deformation. The pressure positioning part 32 includes a pressure positioning hole 320, which is formed through the load-bearing plate 31. The first positioning part 24 includes a first positioning hole formed on the pressure sensor module 21. The first connecting member 4 includes a first screw 41, which passes through the first positioning hole and screws into the pressure positioning hole 320, and is threadedly connected to the pressure positioning hole 320. Furthermore, multiple first positioning holes are arranged circumferentially around the pressure sensor module 21, and the number of pressure positioning holes 320 and first screws 41 are the same as the number of first positioning holes. By setting multiple first positioning holes, pressure positioning holes 320, and first screws 41, the pressure sensor module 21 is pre-positioned, reducing the risk of displacement of the pressure sensor module 21 during installation, which could affect the installation quality and the testing accuracy of the test end 22.

[0030] Specifically, see Figure 2 and Figure 3 The load-bearing component 3 is provided with a compensation component 5 to compensate for deformation. The compensation component 5 is installed below the load-bearing component 3 and has elasticity.

[0031] The compensation component 5 includes a rubber foam layer 51, which is laid on the bottom surface of the load-bearing plate 31. The rubber foam layer 51 is used for anti-slip, reducing the deformation of the overall structure and adjusting the parallelism of the overall structure (or compensating for the gap between the uneven bottom surface and the load-bearing plate 31).

[0032] Specifically, see Figure 2 and Figure 3The housing 1 has multiple sets of fixing parts 13 inside the receiving part 11. The multiple sets of fixing parts 13 are arranged in a rectangular interval inside the receiving part 11. The load-bearing component 3 has a housing positioning part 33, and the compensation component 5 has a compensation positioning part 52. The number of housing positioning parts 33 and compensation positioning parts 52 are the same as the number of fixing parts 13. The housing 1 and the load-bearing component 3 are connected by a second connecting part 6. The number of second connecting parts 6 is the same as the number of fixing parts 13. Each set of second connecting parts 6 passes through the compensation positioning part 52 and the housing positioning part 33 in sequence and then passes into the fixing part 13, and is rotatably connected to the fixing part 13.

[0033] In one embodiment, each set of fixing parts 13 includes a positioning post 130 protruding from the bottom surface of the outer shell 1, and each set of positioning posts 130 has a threaded copper post embedded in it. The end face of each set of positioning posts 130 abuts against the end face of the load-bearing plate 31. The positioning posts 130 are used to buffer and disperse the pressure of external pressure on the outer shell 1, and prevent the outer shell 1 from being damaged due to excessive external force. The shell positioning part 33 includes a shell positioning hole 330 opened on the load-bearing plate 31, and the shell positioning hole 330 is provided through the load-bearing plate 31. The compensation positioning part 52 includes a compensation positioning hole 520 opened on the rubber foam layer 51, and the compensation positioning hole 520 is provided through the rubber foam layer 51. Each set of second connecting parts 6 includes a second screw 61. Each set of second screws 61 passes through the compensation positioning hole 520 and the shell positioning hole 330, and then passes through the positioning post 130, and is threadedly connected to the threaded copper post embedded in the positioning post 130.

[0034] Specifically, see Figures 1 to 3 A buffer layer 25 is bonded to the pressure component 2. The buffer layer 25 is located above the load-bearing component 3, and the edge of the receiving portion 11 of the outer shell 1 abuts against the buffer layer 25. The buffer layer 25 is elastic. A waterproof layer 26 is also laid on the buffer layer 25. The waterproof layer 26 is placed on the buffer layer 25, and the edge of the receiving portion 11 of the outer shell 1 presses against the waterproof layer 26.

[0035] In one embodiment, the buffer layer 25 includes a buffer sponge, which is laid on the pressure sensor module 21, and the edge of the receiving portion 11 abuts against the side of the buffer sponge, thereby restricting the movement of the buffer sponge. The buffer sponge is made of polyurethane foam, which, with its excellent resilience and high water absorption, can better protect the pressure sensor module 21 and provide a good pressure transmission medium.

[0036] In one embodiment, the waterproof layer 26 includes a PVC foot pad layer laid on a cushioning sponge. The edge of the receiving portion 11 presses against the upper surface of the PVC foot pad layer and also abuts against the side of the PVC foot pad layer. The PVC foot pad layer is made of polyvinyl chloride resin, utilizing its properties to achieve anti-slip, wear-resistant, waterproof, and moisture-proof properties.

[0037] Specifically, see Figure 2 and Figure 3 The outer shell 1 has multiple sets of scratch-resistant arc-shaped portions 14, which are arranged around the circumference of the outer shell 1 body.

[0038] The arc-shaped portion 14 includes an arc-shaped edge protruding from the rectangular corner of the outer casing 1. The arc-shaped edge is used to eliminate the sharp corners of the rectangular outer casing 1 and prevent the user from scratching it during use.

[0039] Specifically, the pressure component 2 has a first alignment portion 27, and the load-bearing component 3 has a second alignment portion 34. The first alignment portion 27 and the second alignment portion 34 are aligned and arranged. The outer shell 1 is provided with a locking portion 15, which is inserted into the first alignment portion 27 and the second alignment portion 34 in sequence.

[0040] In one embodiment, the first alignment portion 27 includes a first alignment groove formed on the pressure sensor module 21, the first alignment groove being U-shaped. The second alignment portion 34 includes a second alignment groove formed on the load-bearing plate 31, the second alignment groove being U-shaped. The bottom of the U-shape of the first alignment groove is aligned with the bottom of the U-shape of the second alignment groove. The locking portion 15 includes a locking block protruding from the bottom surface of the housing 1, the locking block passing through the first and second alignment grooves and its side abutting against the pressure sensor module 21 and the load-bearing plate 31.

[0041] Further, see Figure 2 and Figure 3 The housing 1 also has a pressure buffer 16 in its accommodating cavity. The pressure buffer 16 protrudes from the housing 1 and one end abuts against the surface of the pressure sensor module 21.

[0042] Specifically, the pressure buffer part 16 includes a pressure buffer column 160. A second screw 61 is used, which passes through the compensation member 5, the load-bearing member 3, and the pressure member 2 in sequence, and then passes into the pressure buffer column 160 and is threadedly connected to the pressure buffer column 160.

[0043] See Figure 1 and Figure 2 In one embodiment, a light strip 7 is provided on the upper surface of the housing 1. The light strip 7 is electrically connected to the pressure sensor module 21. The light strip 7 is used to display the outline of the test end 22 of the pressure sensor module 21, so as to prevent the tester from not fully stepping on the test end 22 of the pressure sensor module 21 during the test.

[0044] The working principle of the pressure plate assembly structure of this application is as follows: The shell 1, pressure component 2, and load-bearing component 3 form an integrated structure. The pressure-sensitive element plate, serving as the test end 22, is connected to the measuring part 12 of the shell 1, allowing the tester to step on it to detect foot pressure. The pressure sensor module 21 is positioned and connected to the load-bearing plate 31 via the first connector 4 to ensure stable installation. The signal transmission cable 23 is laid within the housing part 11 of the shell 1 to achieve signal transmission. The rubber foam layer 51 below the load-bearing plate 31 compensates for deformation and adjusts parallelism. The shell 1 and the load-bearing component 3 are connected via the second connector 6 and the positioning post 130 to disperse external pressure. The cushioning sponge and PVC foot pad layer provide cushioning protection and waterproofing and anti-slip functions, respectively. The arc-shaped part 14 prevents scratches, and the locking part 15 cooperates with the alignment part to further ensure accurate positioning of each component. The pressure buffer post 160 enhances the protection of the pressure sensor module 21.

[0045] This technical solution achieves stable foot pressure detection and has multiple advantages: the modular structure design facilitates the installation and maintenance of the pressure component 2; the rubber foam layer 51 and the cushioning sponge improve the stability and cushioning performance of the structure, reducing deformation; the PVC foot pad layer ensures anti-slip, wear-resistant, and waterproof effects during use; multiple positioning structures ensure precise installation of each component, avoiding misalignment that affects detection accuracy; and the arc-shaped part 14 improves safety during use. It solves the problems of unstable traditional pressure plate structures, susceptibility to installation misalignment affecting detection accuracy, insufficient protective performance, and inconvenient maintenance.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
