For example, leather seats are typically harder and have moderate elasticity, while memory foam seats have higher elasticity and adaptability. These differences lead to varying degrees of seat deformation under the same pressure or load, thus affecting the sensor's output signal. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a hysteresis difference detection device for seat sensors, which has the advantage of reducing detection errors.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hysteresis difference detection device for a seat sensor, comprising a detection base, a support frame fixedly installed above the detection base, a cylinder fixedly installed above the support frame, the output end of the cylinder extending vertically downward to the inner side of the support frame and fixedly installed with a rectangular plate, connecting rods fixedly installed below both ends of the rectangular plate, a second rectangular plate movably sleeved on the outer side of the connecting rods, a bottom ring block fixedly installed below the second rectangular plate, elastic blocks evenly fixedly installed below the bottom ring block, an arc-shaped block fixedly installed below the elastic blocks, an outer ring block fixedly installed on the outer side of the bottom ring block, a threaded groove opened on the inner side of the outer ring block, a threaded ring movably installed inside the threaded groove, a knob fixedly installed above the threaded ring, a triangular retaining ring fixedly installed below the knob, the triangular retaining ring corresponding to the arc-shaped block, an installation shaft movably installed on the inner side of the arc-shaped block, and a seat cover block fixedly installed below the installation shaft.

[0023] 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.

[0024] like Figures 1 to 7As shown, this utility model provides a hysteresis difference detection device for a seat sensor, including a detection base 1, a support frame 2 fixedly installed above the detection base 1, a cylinder 3 fixedly installed above the support frame 2, the output end of the cylinder 3 extending vertically downward to the inner side of the support frame 2 and fixedly installed with a rectangular plate 4, connecting rods 5 fixedly installed below both ends of the rectangular plate 4, a second rectangular plate 6 movably sleeved on the outer side of the connecting rods 5, and a bottom ring block 9 fixedly installed below the second rectangular plate 6. The bottom ring block 9 is uniformly fixed with... An elastic block 10 is installed, and an arc-shaped block 11 is fixedly installed below the elastic block 10. An outer ring block 12 is fixedly installed on the outer side of the bottom ring block 9. A threaded groove 13 is opened on the inner side of the outer ring block 12. A threaded ring 14 is movably installed inside the threaded groove 13. A knob 15 is fixedly installed above the threaded ring 14. A triangular retaining ring 16 is fixedly installed below the knob 15. The triangular retaining ring 16 corresponds to the arc-shaped block 11. An installation shaft 17 is movably installed on the inner side of the arc-shaped block 11. A seat cover block 18 is fixedly installed below the installation shaft 17.

[0025] When it is necessary to perform hysteresis difference detection on the seat sensor 22, first place the seat sensor 22 inside the groove 21, and then connect its output end to the data analyzer 28. Then, insert the seat cover block 18 of different materials into the inner side of the bottom ring block 9 through the mounting shaft 17. Then rotate the knob 15 to make the knob 15 drive the threaded ring 14 to rotate. The threaded ring 14 rotates inside the threaded groove 13, causing the triangular retaining ring 16 to move upward, so that the triangular retaining ring 16 squeezes the arc block 11 and the elastic block 10, causing the elastic block 10 to deform and drive the arc block 11 to contract inward to fix the mounting shaft 17, thereby fixing the seat cover block 18. Then start the cylinder 3 to drive the rectangular plate 4 to move downward. The rectangular plate 4 drives the rectangular plate 6 to move downward through the connecting rod 5, squeezing the seat sensor 22 through the seat cover block 18. Analyze the data of the pressure sensor 7 and the data of the seat sensor 22 to obtain the hysteresis difference detection data.

[0026] By placing the seat sensor 22 inside the groove 21, and then inserting seat cover blocks 18 of different materials into the inner side of the bottom ring block 9 through the mounting shaft 17, and then rotating the knob 15, the elastic block 10 deforms, causing the arc block 11 to contract inward and fix the mounting shaft 17, thereby fixing the seat cover block 18. Compared with the traditional hysteresis difference detection device for seat sensors, this hysteresis difference detection device for seat sensors uses the deformation of the elastic block 10 to cause the arc block 11 to contract inward and fix the mounting shaft 17, thereby fixing the seat cover block 18. This makes it convenient to use seat cover blocks 18 of different materials to detect the seat sensor 22, making the detection data more accurate.

[0027] The detection base 1 has a foamed surface 20 movably mounted on its surface. A groove 21 is provided above the foamed surface 20. The detection base 1 has movable grooves 23 located on both sides of the foamed surface 20 inside. A protrusion 24 is movably mounted inside the movable groove 23. A return spring 25 is elastically mounted inside the movable groove 23. The return spring 25 is located inside the protrusion 24.

[0028] The foamed surface 20 is inserted into the detection base 1, causing the foamed surface 20 to press against the protrusion 24, which moves inward into the movable groove 23. The protrusion 24 then presses against the reset spring 25, causing the reset spring 25 to deform. Simultaneously, the inward movement of the protrusion 24 drives the limiting block 27 to move inward within the limiting groove 26, thereby limiting the protrusion 24. The reset spring 25 releases its elastic potential energy to push the protrusion 24 outward, thus fixing the foamed surface 20.

[0029] By inserting the foamed surface 20 into the detection base 1, the foamed surface 20 presses against the protrusion 24, and the protrusion 24 presses against the return spring 25. The return spring 25 releases its elastic potential energy to push the protrusion 24 outward, thereby fixing the foamed surface 20. Compared with the traditional hysteresis difference detection device for seat sensors, this hysteresis difference detection device for seat sensors facilitates the detection of seat sensors 22 through the easily replaceable foamed surface 20, thus making it convenient to detect foamed surfaces 20 of different materials or thicknesses.

[0030] Among them, a pressure sensor 7 is fixedly installed on the top of the rectangular plate 2 6. The pressure sensor 7 is movably sleeved on the outside of the connecting rod 5. A telescopic spring 8 is elastically installed between the inside of the rectangular plate 1 4 and the inside of the pressure sensor 7. The telescopic spring 8 is movably connected to the outside of the connecting rod 5.

[0031] Start cylinder 3 to drive rectangular plate 4 downward. Rectangular plate 4 drives rectangular plate 6 downward through connecting rod 5. The seat cover block 18 squeezes the seat sensor 22. The data from pressure sensor 7 and seat sensor 22 are analyzed to obtain the hysteresis difference detection data.

[0032] The detection base 1 has a data analyzer 28 fixedly installed on the front side, and a display screen 29 fixedly installed on the outside of the data analyzer 28.

[0033] The data analyzer 28 collects and analyzes the data from the seat sensor 22 and the pressure sensor 7, thereby detecting the hysteresis difference of the seat sensor 22.

[0034] Among them, the movable groove 23 has limit grooves 26 on both sides, and the bottom of the protrusion 24 is fixedly installed with a limit block 27, which is movably connected inside the limit groove 26.

[0035] The protrusion 24 moves inward, causing the limiting block 27 to move inward inside the limiting groove 26, thereby limiting the protrusion 24.

[0036] A fixing block 19 is fixedly installed below the connecting rod 5, and the fixing block 19 is located below the rectangular plate 6.

[0037] By installing the fixing block 19 at the bottom of the connecting rod 5, the fixing block 19 limits the rectangular plate 6 and prevents the rectangular plate 6 from detaching from the connecting rod 5.

[0038] The seat sensor 22 is movably installed inside the groove 21, and the other end of the seat sensor 22 is movably connected to the inside of the data analyzer 28.

[0039] By placing the seat sensor 22 inside the recess 21 and installing the other end of the seat sensor 22 inside the data analyzer 28, the data from the seat sensor 22 is analyzed and detected by the data analyzer 28.

[0040] Working principle and usage process of this utility model:

[0041] When it is necessary to perform hysteresis difference detection on the seat sensor 22, first place the seat sensor 22 inside the groove 21, and then connect its output end to the data analyzer 28. Then, insert the seat cover block 18 of different materials into the inner side of the bottom ring block 9 through the mounting shaft 17. Then rotate the knob 15 to make the knob 15 drive the threaded ring 14 to rotate. The threaded ring 14 rotates inside the threaded groove 13, causing the triangular retaining ring 16 to move upward, so that the triangular retaining ring 16 squeezes the arc block 11 and the elastic block 10, causing the elastic block 10 to deform and drive the arc block 11 to contract inward to fix the mounting shaft 17, thereby fixing the seat cover block 18. Then start the cylinder 3 to drive the rectangular plate 4 to move downward. The rectangular plate 4 drives the rectangular plate 6 to move downward through the connecting rod 5, squeezing the seat sensor 22 through the seat cover block 18. Analyze the data of the pressure sensor 7 and the data of the seat sensor 22 to obtain the hysteresis difference detection data.

[0042] The foamed surface 20 is inserted into the detection base 1, causing the foamed surface 20 to press against the protrusion 24, which moves inward into the movable groove 23. The protrusion 24 then presses against the reset spring 25, causing the reset spring 25 to deform. Simultaneously, the inward movement of the protrusion 24 drives the limiting block 27 to move inward within the limiting groove 26, thereby limiting the protrusion 24. The reset spring 25 releases its elastic potential energy to push the protrusion 24 outward, thus fixing the foamed surface 20.
