[0002] New energy electric vehicle sensors are components used to monitor and control various functions of the vehicle, and new energy electric vehicle sensors need to be calibrated to ensure the accuracy of their monitoring data and the reliability of their execution actions. New energy electric vehicle sensors are an indispensable part of the electronic regulation system of new energy vehicles. They play a vital role in multiple systems such as the vehicle's power, chassis and body. Common new energy electric vehicle sensors include temperature sensors, pressure sensors, environmental sensors, acceleration sensors, gas sensors and current sensors. These sensors are responsible for monitoring important indicators such as the temperature of the battery and drive system, the pressure of various liquids and gases, environmental factors (such as air quality, humidity), vehicle acceleration and tilt angle, exhaust emissions, and battery current and charging status.

[0003] After searching, the Chinese patent document announcement number: CN215573554U discloses a pressure sensor calibration device for a car seat, including a base, a frame, a button and a display screen.

The bolts drive the clamping plates in the slot plate to move closer between the slot plates, and the pressure sensor placed in the middle of the slot plate is clamped on both sides, which is convenient for subsequent detection."

[0032] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a calibration device for a new energy electric vehicle sensor, including a processing table 1, which provides a working platform for the entire calibration operation.

The driving end of the cylinder 3 is fixedly connected with a sliding block 4, and the sliding block 4 is pushed to slide by driving the cylinder 3. The rear left and right ends of the driving component are fixedly connected with fixed columns 5, thereby driving the fixed columns 5 to slide.

The left and right ends of the sliding block 4 are respectively fixedly connected to the bottom ends of the two fixed columns 5. The outside of the fixed column 5 is rotatably connected with a rotating plate 6, and then the rotating plate 6 is pushed to rotate;

[0033] The far ends of the two rotating plates 6 are rotatably connected with fixed rods 7, which then drive the fixed rods 7 to slide. The bottom side of the fixed rods 7 is fixedly connected with a square plate 8. The fixed rods 7 are fixed to the square plate 8 so that the fixed rods 7 can drive the square plate 8 to slide together when sliding. The far sides of the two square plates 8 are fixedly connected with strip plates 9, thereby driving the strip plates 9 to slide. The tops of the adjacent sides of the two strip plates 9 are fixedly connected with sliders 10, which then drive the sliders 10 to slide. The far ends of the two sliders 10 are provided with sliding components, which include two sliding blocks 12. The outer sides of each two sliding blocks 12 are respectively slidably connected to the inner walls of one of the sliders 10. The sliding blocks 12 are restricted by the sliders 10 so that they can slide horizontally. The adjacent sides of the multiple sliding blocks 12 are fixedly connected with connecting blocks 13. After the connecting blocks 13 are subjected to force, they drive the sliding blocks 12 to slide.

[0034] Two triangular blocks 14 are fixedly connected to the adjacent sides of the two sliding components, and T-shaped openings 11 are provided at the distant ends of the two sliding blocks 10, which are used to limit the movable space between the sliding blocks 12 and the connecting blocks 13. The adjacent sides of the multiple connecting blocks 13 are respectively fixedly connected to the distant sides of the multiple triangular blocks 14, and the connecting blocks 13 are pushed to slide after the triangular blocks 14 are subjected to force. The distant sides of the multiple triangular blocks 14 are fixedly connected with springs 15, and the springs 15 are fixed so that the trapezoidal plates 15 can be subjected to uniform force. The adjacent sides of the multiple triangular blocks 14 are slidably connected with trapezoidal plates 16, and the triangular blocks 14 are pushed to slide by the springs 16.

[0035] Reference Figure 1 and Figure 4 The four corners of the top side of the processing table 1 are fixedly connected with columns 19 to provide support force. The top sides of multiple columns 19 are fixedly connected with top plates 20. The bottom side of the top plate 20 is fixedly connected with electric push rods 21, which are driving sources. The driving end of the electric push rods 21 is fixedly connected with a fixed plate 29. The fixed plate 29 is pushed to slide by driving the electric push rods 21. A plurality of elastic components are arranged in the middle of the fixed plate 29. The plurality of elastic components include sliding shafts 23. The bottom sides of the plurality of sliding shafts 23 are respectively fixedly connected to the top sides of the circular plate 22, and the circular plate 22 is provided with support force through the sliding shafts 23.

[0036] The outsides of multiple sliding shafts 23 are all slidably connected to the middle part of the fixed plate 29. The sliding shafts 23 can slide vertically due to the restriction of the fixed plate 29. The outside of the sliding shaft 23 is sleeved with a spring 24. The bottom sides of multiple springs 24 are respectively fixedly connected to the top side of the circular plate 22 to fix and restrict the spring 24 so that the spring 24 can be evenly stressed. The top side of the elastic component is fixedly connected to an arc plate 25, and the bottom sides of multiple elastic components are fixedly connected to the circular plate 22. A calibration sensor 26 is provided on the bottom side of the circular plate 22. The bottom side of the calibration sensor 26 is fixedly connected to a support rod 27, and the bottom side of the support rod 27 is provided with a calibration plate 28 for calibration.

[0037] Working principle: We place the calibration plate 28 of different shapes and sizes on the bottom side of the processing table 1 and between the two sliders 10, and then drive the sliding block 4 to slide by driving the cylinder 3, and then drive the fixed column 5 to slide, and then the fixed column 5 will drive the rotating plate 6 to rotate with the fixed column 5 as the center point, and the two rotating plates 6 will respectively drive a fixed rod 7 to slide to the adjacent side when rotating, and then drive the square plate 8 to slide, thereby driving the strip plate 9 to slide inside the top of the processing table 1, so that the two sliders 10 slide to the adjacent side to fix the calibration plate 28. When needed When the plate 28 to be calibrated is of a special shape, the plate 28 to be calibrated will first touch the clamping plate 18, so that the clamping plate 18 can slide on the inner wall of the slider 10, and the clamping plate 18 will also drive the limiting plate 17 to slide, and the two limiting plates 17 will respectively drive the two trapezoidal plates 16 to slide, and each trapezoidal plate 16 will push a triangular block 14, so that a pair of triangular blocks 14 inside each slider 10 can slide to the far side, and each triangular block 14 will squeeze a spring 15, so that the spring 15 can store elastic potential energy, and then can be adaptively adjusted according to the shape and size of the clamped object;

[0038] After the calibration plate 28 to be inspected is fixed, the fixed plate 29 is pushed to slide on the outside of the column 19 by driving the electric push rod 21, and then the circular plate 22 will slide downward under the influence of gravity. At the same time, the arc plate 25 and the sliding shaft 23 are fixed and the arc plate 25 will be on the top side of the fixed plate 29. The sliding shaft 23 will provide support for the circular plate 22, so that the calibration plate 28 can contact the calibration plate 28 to be inspected, and then provide a reaction to the top, so that the circular plate 22 can push the sliding shaft 23 to slide inside the fixed plate 29. At the same time, the circular plate 22 will also squeeze the multiple springs 24, so that the springs 24 can store elastic potential energy, and then give the calibration plate 28 a reverse force to fit the calibration plate 28 to be inspected, thereby reducing the hard contact between the calibration plate 28 and the sensor, and then avoiding possible damage to the sensitive sensor.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
