DETAILED DESCRIPTION

[0023] In order to further understand the content of the utility model, the utility model is described in detail in combination with the drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model and are not limited.

[0024] In a first aspect, as Figure 1 andFigure 2 As shown, the embodiment provides a pressure detection sensor, which comprises a mounting member 100 that can be mounted to an external component, a matching member 200 connected to the mounting member 100, and a sensor 300 attached to the matching member 200. It can be understood that the mounting member 100 is used for positioning and mounting and provides support for the matching member 200, and the matching member 200 has a certain elastic deformation capacity. When the matching member 200 is subjected to external pressure, the matching member 200 will deform accordingly, and the degree of deformation of the matching member 200 will change with the change of the external pressure. During the deformation of the matching member 200, the sensor 300 attached to the matching member 200 can detect the degree of deformation of the matching member 200, and then output the corresponding pressure value through the detected degree of deformation of the matching member 200, thereby realizing the detection of the pressure.

[0025] It should be noted that as the degree of deformation of the matching member 200 gradually increases, the pressure value output by the sensor 300 through detection also gradually increases, and as the degree of deformation of the matching member 200 gradually decreases, the pressure value output by the sensor 300 through detection also gradually decreases. Further, the detection of the degree of deformation of the matching member 200 by the sensor 300 can be achieved by detecting the distance or the displacement amount, for example, the sensor 300 detects the distance between any side surface of the matching member 200 or the displacement amount of the sensor 300 itself.

[0026] Further, compared with the thin film sensor 300, the structure of the external component needs to be modified to adapt to the installation and use of the thin film sensor 300, and the pressure needs to be transmitted to the thin film sensor 300 itself to make the thin film sensor 300 itself deform, so that the volume of the thin film sensor 300 is required when used. In the embodiment, the external pressure is converted into the deformation of the matching member 200, and then the deformation of the matching member 200 is detected by the sensor 300 to output the pressure value, thereby realizing the detection of the pressure, which can preferably enhance the applicability and reduce the use cost.

[0027] In some embodiments, a circuit board 310 or FPC wire (not shown in the figure) is attached to the matching member 200, and the sensor 300 is electrically connected to the circuit board 310 or FPC wire, so that the sensor 300 can be indirectly attached to the matching member 200 through the circuit board 310 or FPC wire.

[0028] It can be understood that the circuit board 310 or FPC wire can preferably provide power supply for the sensor 300 and meet the signal transmission between the sensor 300 and other components, for example, the sensor 300 transmits the pressure value to an external controller after detecting the deformation of the matching member 200.

[0029] Further, when the matching piece 200 is subjected to external pressure, the matching piece 200 deforms accordingly. In this process, since the circuit board 310 or the FPC wire is attached to the matching piece 200, the center position of the circuit board 310 or the FPC wire will be offset relative to the whole of the matching piece 200, and the sensor 300 can detect the offset and output a pressure value corresponding thereto, thereby achieving detection of the pressure.

[0030] In some embodiments, a mounting cavity 210 is formed in the inside of the matching piece 200, and the circuit board 310 or the FPC wire is attached to the inner side wall of the mounting cavity 210, so that the sensor 300 electrically connected to the circuit board 310 or the FPC wire is also in the mounting cavity 210.

[0031] It can be understood that by installing the circuit board 310 or the FPC and the sensor 300 in the mounting cavity 210 of the matching piece 200, the circuit board 310 or the FPC and the sensor 300 can be wrapped by the matching piece 200, so that the matching piece 200 can better protect the circuit board 310 or the FPC and the sensor 300 from damage due to external impact or extrusion, and has higher stability. At the same time, since the mounting cavity 210 is formed in the inside of the matching piece 200, the matching piece 200 can have a thin-wall structure, thereby better improving the deformation ability of the matching piece 200, making the matching piece 200 more sensitive to external pressure and more likely to deform, so that the sensor 300 in the mounting cavity 210 can more quickly and accurately detect the external pressure.

[0032] In some embodiments, the mounting cavity 210 formed in the inside of the matching piece 200 is open on the connecting surface of the matching piece 200 and the mounting piece 100. It can be understood that the mounting piece 100 and the matching piece 200 are manufactured separately and are fixedly connected together by adhesion or bolts. Since the mounting cavity 210 is open on the matching piece 200, the circuit board 310 or the FPC and the sensor 300 can be easily installed in the mounting cavity 210 for use, and are convenient to disassemble, replace or repair.

[0033] Further, when the mounting piece 100 and the matching piece 200 are fixedly connected, the mounting piece 100 can seal the mounting cavity 210 on the matching piece 200, thereby forming a closed space in the mounting cavity 210 to achieve a sealing effect of the mounting cavity 210, achieving the effect of waterproof and dustproof, and further improving the stability of the circuit board 310 or the FPC and the sensor 300 in use.

[0034] In some embodiments, a through hole 220 is formed on the circumferential side wall of the fitting piece 200, through which the circuit board 310 or FPC flat cable inside the mounting cavity 210 can be connected with a cable (not shown in the figure) outside to realize power supply and signal transmission of the circuit board 310 or FPC flat cable. Further, a sealing ring (not shown in the figure) is arranged on the through hole 220, so that the cable can pass through while the mounting cavity 210 is sealed.

[0035] In some embodiments, the circuit board 310 or FPC flat cable is attached to the center position of the inner side wall of the mounting cavity 210 away from the mounting piece 100. When the fitting piece 200 is subjected to external pressure, the inner side wall of the mounting cavity 210 away from the mounting piece 100 is more likely to deform, and further, the center position of the inner side wall of the mounting cavity 210 away from the mounting piece 100 is more likely to deform, so that the center position of the circuit board 310 or FPC flat cable is more likely to deviate from the fitting piece 200 as a whole, so that the detection of the sensor 300 is faster and more accurate.

[0036] Further, an extrusion column 230 is arranged on one end of the fitting piece 200 away from the mounting piece 100, and the position of the extrusion column 230 corresponds to the position of the circuit board 310 or FPC flat cable, that is, the position of the extrusion column 230 corresponds to the center position of the inner side wall of the mounting cavity 210 away from the mounting piece 100. The pressure from the outside will first act on the extrusion column 230, and then the extrusion column 230 will extrude the fitting piece 200, and the extrusion column 230 can directly transmit the pressure to the center position of the inner side wall of the mounting cavity 210 away from the mounting piece 100, so that the center position of the inner side wall of the mounting cavity 210 away from the mounting piece 100 can be directly deformed, so that the deformation is more sensitive and fast, and further, the detection of the sensor 300 can be faster and more accurate.

[0037] In some embodiments, a pressure receiving piece 240 is arranged on the end of the extrusion column 230 away from the fitting piece 200, and the pressure from the outside will first act on the pressure receiving piece 240, and then the pressure receiving piece 240 will transmit the pressure to the extrusion column 230 to extrude the center position of the inner side wall of the mounting cavity 210 away from the mounting piece 100.

[0038] Further, in the radial direction of the extrusion column 230, the size of the pressure receiving piece 240 is greater than the size of the extrusion column 230. In this embodiment, the pressure receiving piece 240 is disc-shaped, and the extrusion column 230 and the pressure receiving piece 240 are coaxially arranged, and the radial size of the pressure receiving piece 240 is greater than the radial size of the extrusion column 230.

[0039] It can be understood that the radial dimension of the pressure receiving part 240 is greater than the radial dimension of the extrusion column 230, so that the pressure receiving part 240 has a larger force bearing area for bearing the external pressure, so that the pressure receiving part 240 can better bear the pressure from the outside, and can bear the external pressure in a larger range, avoiding the external pressure acting directly on the extrusion column 230 with a smaller radial dimension, so that the pressure receiving part 240 can transmit the pressure to the extrusion column 230 with a smaller radial dimension, so that the pressure can more concentratedly act on the fitting part 200, thereby better driving the installation cavity 210 to deform away from the center position of the inner side wall of the mounting part 100, thereby making the detection of the sensor 300 more rapid, sensitive and accurate.

[0040] In some embodiments, a boss 110 is arranged on one end of the mounting part 100 away from the fitting part 200, and in the radial direction of the boss 110, the size of the boss 110 is greater than the size of the mounting part 100.

[0041] It should be noted that the mounting part 100 and the boss 110 can be connected with an external component. Specifically, since in the radial direction of the boss 110, the size of the boss 110 is greater than the size of the mounting part 100, the boss 110 can be installed on the external component by means of clamping connection or interference fit, so as to realize the fixed installation of the mounting part 100 on the external component. Of course, the mounting part 100 can also be fixed on the external component by means other than clamping connection, which is not particularly limited.

[0042] Further, a connecting hole 111 is formed on one end of the boss 110 away from the mounting part 100, and the boss 110 can be connected with an external component through the connecting hole 111.

[0043] In a second aspect, in combination with Figure 3 As shown, in the present embodiment, a two-wheeled vehicle is provided, which comprises a seat bucket 20 and a seat cushion 10 capable of being arranged on the seat bucket 20. The pressure detection sensor 40 described above is arranged on the side wall of the seat cushion 10 facing the seat bucket 20, and / or the pressure detection sensor 40 described above is arranged on the side wall of the seat bucket 20 facing the seat cushion 10, that is, the external component can be the seat cushion 10 and / or the seat bucket 20.

[0044] Further specifically, a rubber plug 30 is usually arranged on the seat cushion 10 and / or the seat bucket 20. The pressure detection sensor 40 in the present embodiment can replace the rubber plug 30, so that the pressure detection sensor 40 is arranged at the position of the rubber plug 30, so that when the pressure detection sensor 40 is applied to the two-wheeled vehicle, the structure of the seat cushion 10 and / or the seat bucket 20 does not need to be additionally modified, the applicability is high, and the use cost can be reduced.

[0045] In summary, the above only for the preferred embodiments of the present application, any changes and modifications made in accordance with the present application patent scope, should be the scope of the present application patent cover.
