Description

Technical Field

[0001] The utility model relates to the technical field of flexible sensors, in particular to a fixing structure for a flexible sensor. Background Technique

[0002] Flexible electronics is a general term for a technology, which is a new electronic technology that fabricates organic / inorganic material electronic devices on flexible / ductile substrates. Compared with traditional electronics, flexible electronics has greater flexibility and can, to a certain extent, adapt to different working environments and meet the deformation requirements of devices. However, the corresponding technical requirements also restrict the development of flexible electronics. First, the stretchability and bendability of flexible electronics without damaging its own electronic performance pose new challenges and requirements for the circuit manufacturing materials; second, the preparation conditions of flexible electronics and the performance of various electronic devices that make up the circuit are still insufficient compared with traditional electronic devices, which is also a major problem in its development.

[0003] According to a fixing structure for a flexible sensor that is easy to install with the application number 202022544151.7, the positions of the sensing sheet and the wire are restricted by two limit blocks and groove two, and are clamped into groove three by the clamping block, which facilitates the connection between the two substrates, reduces the installation difficulty of the sensor, and increases the stability between them.

[0004] However, the above fixing structure has certain deficiencies. Due to the deformation and bending requirements of the flexible sensor, when it is bent, the connection parts of the wire and the sensing sheet with the substrate will inevitably be subjected to large or small tensile forces. When subjected to tensile forces for a long time, the connection between the wire and the sensing sheet is extremely likely to become loose and damaged, resulting in the flexible sensor being unable to continue to be used. And the above fixing structure does not have a structure for buffering and protection, so the above problems will inevitably occur. For this reason, we have proposed a fixing structure for a flexible sensor. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a fixing structure for a flexible sensor, which solves the problems put forward in the above background technique.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: A fixing structure for a flexible sensor, including a substrate and a mounting plate. A vertical plate is fixedly installed at the bottom of the mounting plate, a head is fixedly installed at the bottom of the vertical plate, several wires are arranged at one end of the head, a buffer groove is opened inside the substrate, several silicone rubber blocks are fixedly installed inside the buffer groove, the mounting plate cooperates with the silicone rubber blocks, two limit sliding grooves are opened inside the mounting plate, and a pressing plate is installed on one side of the substrate and outside the buffer groove. Two limit sliding plates are fixedly installed on one side of the pressing plate, and the limit sliding plates cooperate with the limit sliding grooves.

[0007] Preferably, one end of the wire is fixedly installed with an induction sheet, and a plurality of installation grooves are formed inside the substrate, and the induction sheet is matched with the installation grooves.

[0008] Preferably, a limiting plate is fixedly installed at the top inside the installation groove, the induction sheet is matched with the limiting plate, and a plurality of pressing blocks are fixedly installed on one side of the pressing plate, and the pressing blocks are matched with the induction sheet.

[0009] Preferably, clamping grooves are formed on both sides of the buffer groove inside the substrate, and two clamping blocks are fixedly installed on one side of the limiting sliding plate, and the clamping blocks are matched with the clamping grooves.

[0010] Preferably, the mounting plate is located in the middle of a plurality of silicone rubber blocks.

[0011] Preferably, the silicone rubber block has flexibility, resilience and high temperature resistance.

[0012] The utility model provides a fixing structure for a flexible sensor, which has the following beneficial effects:

[0013] 1. For the fixing structure for the flexible sensor, through the cooperation of the mounting plate, vertical plate, end head, wire, buffer groove, silicone rubber block, limiting sliding groove, pressing plate and limiting sliding plate, when the mounting plate is installed inside the buffer groove and limited by the pressing plate, the limiting sliding plate is clamped into the limiting sliding groove to guide and limit the mounting plate. When the sensor deforms and bends, the mounting plate and the vertical plate will displace in the buffer groove after receiving a certain pulling force. At the same time of displacement, the silicone rubber block will buffer it, thereby effectively avoiding the situation that the connection part between the wire and the induction sheet is pulled loose and damaged.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Please refer to Figures 1 to 6 , the present invention provides a technical solution: a fixing structure for a flexible sensor, including a substrate 1 and a mounting plate 2. A vertical plate 3 is fixedly installed at the bottom of the mounting plate 2, and an end head 4 is fixedly installed at the bottom of the vertical plate 3. One end of the end head 4 is provided with a plurality of lead wires 5, and the end head 4 is connected to the output end of the lead wire 5. A buffer groove 6 is opened inside the substrate 1, and a plurality of silicone rubber blocks 7 are fixedly installed inside the buffer groove 6. The silicone rubber blocks 7 have flexibility, resilience and high temperature resistance. Among them, the silicone rubber blocks 7 have elasticity by themselves. When the mounting plate 2 generates displacement, it will squeeze the silicone rubber blocks 7. While squeezing the silicone rubber blocks 7, their own elasticity will play a buffering role. After the buffering is completed, the mounting plate 2 can be reset by rebounding. The mounting plate 2 is located in the middle of a plurality of silicone rubber blocks 7, and the mounting plate 2 cooperates with the silicone rubber blocks 7. Two limit sliding grooves 8 are opened inside the mounting plate 2. A pressing plate 9 is installed on one side of the substrate 1 and outside the buffer groove 6. Two limit sliding plates 10 are fixedly installed on one side of the pressing plate 9, and the limit sliding plates 10 cooperate with the limit sliding grooves 8.

[0023] One end of the lead wire 5 is fixedly installed with an induction sheet 13. Among them, a certain length is reserved for the lead wire 5 in the middle of the mounting plate 2 and the induction sheet 13, which can avoid the connection part of the lead wire 5 and the induction sheet 13 from being pulled when the mounting plate 2 is displaced. Among them, the lead wire 5 is connected to the output end of the induction sheet 13. A plurality of mounting grooves 14 are opened inside the substrate 1, and the induction sheet 13 cooperates with the mounting grooves 14. A limit plate 15 is fixedly installed at the top inside the mounting groove 14, and the induction sheet 13 cooperates with the limit plate 15. A plurality of pressing blocks 16 are fixedly installed on one side of the pressing plate 9, and the pressing blocks 16 cooperate with the induction sheet 13. Card slots 11 are opened on both sides of the buffer groove 6 inside the substrate 1. Two card blocks 12 are fixedly installed on one side of the limit sliding plate 10, and the card blocks 12 cooperate with the card slots 11. Among them, the functions of the limit plate 15 and the pressing block 16 are to fix and limit the induction sheet 13. Among them, the functions of the card slots 11 and the card blocks 12 are to facilitate the installation of the pressing plate 9 on one side of the substrate 1.

[0024] In summary, for the fixing structure of the flexible sensor, during use, first place the mounting plate 2 in the middle of several silicone rubber blocks 7 inside the buffer groove 6. Then, push the sensing sheet 13 from below the mounting groove 14 and limit its top through the limiting plate 15. Finally, connect the pressing plate 9 to the card slot 11 through the card block 12. While connecting, snap the limiting sliding plate 10 into the inner side of the limiting sliding groove 8 to limit the mounting plate 2, and then the installation and fixation can be completed. The installation is convenient and fast.

[0025] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
