Detailed Implementation

[0028] 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. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0029] Firstly, such as Figures 1-5 As shown, this embodiment provides a pressure detection sensor 30, which includes a first connector 100 and a second connector 200 capable of being connected and installed with external components, and a first elastic element 110 and a sensor 210 respectively disposed on the first connector 100 and the second connector 200. Specifically, the first elastic element 110 can be disposed on either the first connector 100 or the second connector 200, while the sensor 210 is disposed on either the corresponding second connector 200 or the first connector 100. During installation and use, the first connector 100 and the second connector 200 are respectively installed on two external components that are positioned opposite each other, so that after installation, the first connector 100 and the second connector 200 can remain in a relative position. In this state, the first elastic element 110 can cooperate with the sensor 210, so that when the first connector 100 and / or the second connector 200 are subjected to external pressure, the first connector 100 and the second connector 200 move closer to each other, enabling the sensor 210 to detect the external pressure.

[0030] It can be understood that when the first connecting piece 100 and / or the second connecting piece 200 are subjected to external pressure, the first connecting piece 100 and the second connecting piece 200 can be close to each other, so that the first elastic piece 110 is compressed. Since the first elastic piece 110 cooperates with the sensor 210, the elastic force of the first elastic piece 110 after being compressed can be detected by the sensor 210. Since the external pressure indirectly acts on the first elastic piece 110 through the first connecting piece 100 and the second connecting piece 200, the detection of the elastic force of the first elastic piece 110 can better achieve the detection of the external pressure.

[0031] Further, the first elastic piece 110 can be a spring or an elastic rubber component with elastic properties.

[0032] Further, compared with the thin film sensor 210, the structure of the external component needs to be additionally modified to adapt to the installation and use of the thin film sensor 210, and the pressure needs to be transmitted to the thin film sensor 210 itself to make the thin film sensor 210 itself deform, so that the volume of the thin film sensor 210 is required when in use. In the embodiment, the external pressure is converted into the deformation of the first elastic piece 110, and then the elastic force of the first elastic piece 110 is detected by the sensor 210 to output the pressure value, so as to realize the detection of the pressure. The application can better enhance the applicability and reduce the use cost.

[0033] In some embodiments, the first elastic piece 110 is specifically arranged on the first connecting piece 100, and the sensor 210 is specifically arranged on the second connecting piece 200. The mounting seat 220 is further arranged on the second connecting piece 200, and the mounting cavity 221 is arranged in the mounting seat 220. The sensor 210 is attached to the inner side wall of the mounting cavity 221.

[0034] When the first connecting piece 100 and the second connecting piece 200 are arranged opposite to each other, the first elastic piece 110 arranged on the first connecting piece 100 can abut on the mounting seat 220. When the first connecting piece 100 and / or the second connecting piece 200 are subjected to external pressure, the first connecting piece 100 and the second connecting piece 200 are close to each other, so that the first elastic piece 110 is compressed and extruded on the mounting seat 220. Since the mounting cavity 221 exists, the mounting seat 220 has a shell structure, so that when the elastic force of the first elastic piece 110 acts on the mounting seat 220, the mounting seat 220 will deform to a certain extent. Since the sensor 210 is attached to the inner side wall of the mounting cavity 221, the sensor 210 can detect the deformation of the mounting seat 220, so that the sensor 210 can detect the elastic force of the first elastic piece 110 through the deformation of the mounting seat 220, and then realize the detection of the external pressure.

[0035] It should be noted that as the external pressure increases, the elastic force of the first elastic member 110 increases synchronously, and the deformation amount of the mounting seat 220 under the extrusion of the first elastic member 110 also increases synchronously. As the external pressure decreases, the elastic force of the first elastic member 110 decreases synchronously, and the deformation amount of the mounting seat 220 under the extrusion of the first elastic member 110 also decreases synchronously.

[0036] Further, the detection of the deformation amount of the mounting seat 220 by the sensor 210 can be achieved by detecting the distance or detecting the displacement, for example, detecting the distance between the sensor 210 and a certain inner side wall of the mounting cavity 221, or detecting the relative position between the sensor 210 and a certain inner side wall of the mounting cavity 221, which is not particularly limited.

[0037] In some embodiments, the mounting cavity 221 is open on the side of the mounting seat 220 facing the second connecting member 200, so that the sensor 210 can be conveniently installed and connected in the mounting cavity 221.

[0038] In some embodiments, a positioning column 222 is provided on the side of the mounting seat 220 facing the first connecting member 100, and the first elastic member 110 provided on the first connecting member 100 has an end away from the first connecting member 100 sleeved outside the positioning column 222, so that the stability of the first elastic member 110 abutting on the mounting seat 220 can be preferably improved, and the misalignment of the first elastic member 110 and the mounting seat 220 can be avoided.

[0039] In some embodiments, a limiting ring 120 is provided on the side of the first connecting member 100 facing the second connecting member 200, and the limiting ring 120 is wrapped outside the end of the first elastic member 110 connected with the first connecting member 100, so that the end of the first elastic member 110 can be blocked and supported, and the stability of the connection between the first elastic member 110 and the first connecting member 100 can be improved, and the misalignment of the first elastic member 110 and the first connecting member 100 can be avoided.

[0040] In some embodiments, in the state that the first connecting member 100 and the second connecting member 200 are oppositely arranged, a second elastic member 300 is further arranged between the first connecting member 100 and the second connecting member 200, and the second elastic member 300 is sleeved outside the limiting ring 120, the first elastic member 110, the positioning column 222 and the mounting seat 220.

[0041] Further, the second elastic member 300 can be a spring or an elastic rubber component with elastic properties.

[0042] It can be understood that the two ends of the second elastic member 300 are fixedly connected to the first connecting member 100 and the second connecting member 200 respectively, so that the second elastic member 300 can keep the stability of the first connecting member 100 and the second connecting member 200 during the relative movement of the first connecting member 100 and the second connecting member 200, and keep the first connecting member 100 and the second connecting member 200 in the relative arrangement state all the time, preferably avoid the dislocation of the first connecting member 100 and the second connecting member 200, so that the first elastic member 110 can be positively extruded on the mounting seat 220.

[0043] In some embodiments, the circuit board 211 or the FPC flat cable (not shown in the figure) is attached to the inner side wall of the mounting cavity 221, and the sensor 210 is electrically connected to the circuit board 211 or the FPC flat cable, thereby indirectly attaching the sensor 210 to the inner side wall of the mounting cavity 221. It should be noted that the circuit board 211 or the FPC flat cable can supply power to the sensor 210 on the one hand, and can realize information transmission between the sensor 210 and the external controller on the other hand.

[0044] When the first connecting member 100 and the second connecting member 200 approach each other, the first elastic member 110 will extrude the mounting seat 220 to make the mounting seat 220 deform. Since the circuit board 211 or the FPC flat cable is attached to the inner side wall of the mounting cavity 221, the relative position between the circuit board 211 or the FPC flat cable and the inner side wall of the mounting cavity 221 will be offset during this process, and the sensor 210 can detect the position offset between the circuit board 211 or the FPC flat cable and the inner side wall of the mounting cavity 221, thereby achieving the purpose of detecting the elastic force of the first elastic member 110, and further realizing the detection of the external pressure.

[0045] Further, the via hole 223 which is in communication with the mounting cavity 221 is formed in the mounting seat 220, and the via hole 223 can pass the cable (not shown in the figure) connected to the circuit board 211 or the FPC flat cable.

[0046] In some embodiments, the circuit board 211 or the FPC flat cable arranged in the mounting cavity 221 is attached to the middle position of the inner side wall of the mounting cavity 221 away from the second connecting member 200, and the position of the first elastic member 110 corresponds to the position of the circuit board 211 or the FPC flat cable, that is, when the first connecting member 100 and the second connecting member 200 are arranged relative to each other, the first elastic member 110 abuts on the position of the mounting seat 220 corresponding to the circuit board 211 or the FPC flat cable.

[0047] Further, since the first elastic member 110 abuts on the mounting seat 220 at a position corresponding to the circuit board 211 or the FPC wire, that is, the positioning column 222 is also arranged on the mounting seat 220 at a position corresponding to the circuit board 211 or the FPC wire.

[0048] It should be noted that since the mounting cavity 221 is far away from the middle position of the inner side wall of the second connecting member 200, the deformation effect thereof is optimal when being pressed, and by arranging the first elastic member 110 to abut on the mounting seat 220 at this position, when the first elastic member 110 is pressed by the first connecting member 100 and the second connecting member 200, the mounting cavity 221 far away from the inner side wall of the second connecting member 200 can timely deform when the mounting seat 220 is pressed by the first elastic member 110, and then is quickly detected by the sensor 210, so that the detection efficiency is higher. Further, since the circuit board 211 or the FPC wire is attached at the middle position of the mounting cavity 221 far away from the inner side wall of the second connecting member 200, the position offset between the circuit board 211 or the FPC wire and the inner side wall of the mounting cavity 221 can also be timely generated, and then is quickly detected by the sensor 210, so that the detection efficiency is higher.

[0049] In some embodiments, the first connecting member 100 is provided with a first buckle member 130, so that the first connecting member 100 can be better connected with external components, and further, the second connecting member 200 is provided with a second buckle member 230, so that the second connecting member 200 can be better connected with external components.

[0050] It should be noted that the first connecting member 100 and the second connecting member 200 can also be fixedly installed on external components by means of adhesion or bolt connection, and the like, and no particular limitation is made thereto.

[0051] In a second aspect, as shown in Figure 6 In this embodiment, a two-wheeled vehicle is provided, which includes a seat bucket 10 and a seat cushion 20, and the seat cushion 20 can be fixedly arranged on the seat bucket 10. The seat cushion 20 includes a sponge body 21 and a bottom shell 22, and the sponge body 21 is fixedly installed on the bottom shell 22, so that the bottom shell 22 can carry the sponge body 21.

[0052] Further, the pressure detection sensor 30 is arranged between the sponge 21 and the bottom shell 22, that is, the sponge 21 and the cushion 20 are external components, specifically, the first connecting piece 100 is fixedly installed on one side of the sponge 21 facing the cushion 20 in a bonding manner, and the second connecting piece 200 is fixedly connected to one side of the cushion 20 facing the sponge 21 through the second buckle piece 230. When the user sits on the cushion 20, the first connecting piece 100 and the second connecting piece 200 are close to each other, so that the first elastic piece 110 is compressed and presses the mounting seat 220, so that the mounting seat 220 is deformed, and the inner side wall of the mounting cavity 221 is displaced from the circuit board 211 or the FPC wire, the sensor 210 detects the displacement and outputs a corresponding pressure value, preferably realizing the detection of the pressure.

[0053] In summary, the above only describes the preferred embodiments of the present application, and any changes and modifications made within the scope of the present application should be included in the scope of the present application.
