Therefore, an embedded flexible force sensor device is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1 to 3This utility model provides an embodiment of an embedded flexible force-sensitive sensor, including a main housing 1 that provides support for the overall device. Two knobs 3 are slidably connected to the top of the main housing 1. These knobs activate the following structure: a bevel gear a4 is fixedly connected to the bottom of the two knobs 3; a bevel gear b5 is meshed with the front of the bevel gear a4; a threaded rod 26 is threaded internally connected to the bevel gear b5; the forward and backward movement of the threaded rod 26 moves the retaining strips 12 on both sides, achieving the embedded installation effect; a retaining ring 6 is fixedly connected to the outer wall of the bevel gear b5 to fix it and prevent it from moving with the threaded rod 26 due to rotation; a limiting plate 7 is slidably connected to the outer wall of the retaining ring 6; the cooperation of the limiting plate 7 and the retaining ring 6 secures the bevel gear b5. Gear b5 restricts horizontal movement and allows only rotation. A connecting post 8 is slidably connected to the front side of the threaded rod 26. A retaining strip 12 is used to connect the two sides. Two connecting plates 9 are fixedly connected to the front side of the connecting post 8. A fixing post 10 is slidably connected to the outer wall of the two connecting plates 9. Two connecting long plates 11 are slidably connected to the outer wall of the fixing post 10. The other end of the two connecting long plates 11 is slidably connected to the fixing post 10. A connecting plate 9 is slidably connected to the outer wall of the fixing post 10. A retaining strip 12 is fixedly connected to one end of the connecting plate 9. A limit block 13 is slidably connected to the outer wall of the retaining strip 12. The outer wall of the retaining strip 12 is slidably connected to the inner wall of the main body shell 1. When the knob is turned 3, the retaining strip 12 can be extended or retracted to both sides through the internal structure, achieving the effect of seamless embedded installation.

[0027] Reference Figure 1 , Figure 4 , Figure 5A flexible rubber sheet 2 is fixedly connected inside the main body shell 1. A wire 25 is fixedly connected to the right side of the flexible rubber sheet 2, connecting the flexible rubber sheet 2. A conversion element 14 is fixedly connected to the right side of the wire 25, used to convert the force received by the flexible rubber part into an electrical signal. One end of the wire 25 is fixedly connected to the right side of the flexible rubber sheet 2, used to transmit the resistance signal of the flexible rubber sheet 2, and the other end of the wire 25 is fixedly connected to the left side of the conversion element 14. A wire 25 is fixedly connected to the front side of the conversion element 14, and a calibration element 15 is fixedly connected to the front side of the wire 25. One end of the wire 25 is fixedly connected to the front side of the conversion element 14, and the other end of the wire 25 is fixedly connected to the rear side of the calibration element 15. A wire 25 is fixedly connected to the right side of the conversion element 14, and a circuit board 16 is fixedly connected to the right side of the wire 25. One end of the wire 25 is fixedly connected to the right side of the conversion element 14, used to transmit the converted electrical signal, and the other end of the wire 25 is fixedly connected to the right side of the conversion element 14. On the left side of circuit board 16, circuit board 16 is fixedly connected inside the main body shell 1, which serves a protective function. A fixing block a17 is fixedly connected inside the main body shell 1, which serves a supporting function. A limiting ring a18 is fixedly connected to the top of the fixing block a17. A circular chamber 20 is slidably connected inside the limiting ring a18 for moving and discharging aluminum ball 21. A positive aluminum block 19 is fixedly connected to the left side of the circular chamber 20; a negative aluminum block 24 is fixedly connected to the right side of the circular chamber 20. A limiting ring b23 is slidably connected to the outer wall of the circular chamber 20. A fixing block b22 is fixedly connected to the bottom of the limiting ring b23. The main body shell 1 is fixedly connected to the bottom of the fixing block b22. An aluminum ball 21 is slidably connected inside the circular chamber 20. When the positive and negative poles receive static electricity, the aluminum ball 21 inside the circular chamber 20 reciprocates until all the static electricity is converted into kinetic energy and completely consumed. At this time, the static electricity has been consumed, thereby achieving the effect of eliminating static electricity.

[0028] Working principle: Rotating knob 3 drives bevel gear a4 to rotate, which in turn drives bevel gear b5 to rotate. This causes the internal threaded rod 26 to move back and forth due to the thread, which in turn drives the two connecting plates 11 connected by the fixed column 10 on the front side to move under the limiting action of the limiting block 13. This causes the locking strip 12 to move horizontally left and right. The limiting plate 7 restricts the forward and backward movement of bevel gear b5 to ensure the displacement of bevel gear b5 during operation. When in use, tightening knob 3 shrinks the locking strip 12. After placing it into the target system, rotating knob 3 in the opposite direction unfolds the locking strip 12, so that it is locked in the target system, thus achieving a seamless integration with the target system.

[0029] Secondly, when static electricity passes through the device, the positive aluminum block 19 and the negative aluminum block 24 inside sense the static electricity and transmit it to the aluminum ball 21 inside the circular chamber 20. The electrical signal is converted into force, causing it to reciprocate inside the circular chamber 20 until the static electricity is consumed, thereby achieving the effect of eliminating static electricity.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
