Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure sensor experimental technology, specifically to a pressure sensor experimental device. Background Technology
[0002] A pressure sensor is a device that can sense pressure signals and convert them into output electrical signals. Pressure sensors typically consist of a pressure-sensitive element and a signal processing unit. Among them, diaphragm pressure sensors, which are used to measure solid pressure, are thin and are often used to detect foot pressure, seat pressure, windshield wiper pressure, mold closing pressure, etc. During use, users can intuitively see the pressure distribution and read the values. Diaphragm pressure sensors can detect position information, pressure distribution information, and pressure magnitude information.
[0003] In practical applications of diaphragm pressure sensors, such as those used for detecting foot pressure distribution, seat pressure distribution, and mold closing pressure distribution, a large-area diaphragm pressure sensor is required to accurately detect different pressures at different locations. However, during long-term use, diaphragm pressure sensors may experience reduced sensitivity at certain locations or circuit failures. This can lead to inaccurate pressure detection at a damaged location on the diaphragm, affecting the overall functionality of the device. When users need to manually perform a rough check on the diaphragm pressure sensor's functionality, it is inconvenient to conduct experimental testing to verify its condition. Utility Model Content
[0004] (I) Technical problems to be solved
[0005] The technical problem this invention aims to solve is that diaphragm pressure sensors are mainly used to detect and read pressure at different locations. After long-term use, it is inconvenient for users to manually test the quality of the diaphragm pressure sensor.
[0006] (II) Technical Solution
[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a pressure sensor experimental device, including a sensor body, a lifting assembly, and a cover that cooperates with the sensor body. The cover has at least one guide cylinder that is evenly arranged inside, and each guide cylinder has a weight rope inserted into it. The lower end of each weight rope is provided with a pressure hammer that cooperates with the sensor body. The lifting assembly drives each pressure hammer to rise and fall simultaneously. The lifting assembly includes a lifting plate that is fixedly connected to the upper end of each weight rope. Each of the four corners of the lower end of the lifting plate is fixedly connected with a rod. The cover has a slot that cooperates with the rod. The upper end of the lifting plate is provided with a gripping plate.
[0008] As an improvement, corner pads are glued to the four corners of the bottom of the cover.
[0009] As an improvement, the grip plate is provided with opposing levels, and the levels on both sides are symmetrical about the center position of the grip plate.
[0010] As an improvement, a guide plate is fixedly connected to the lower end of the lifting plate, and a guide groove that cooperates with the guide plate is provided inside the cover.
[0011] As an improvement, an anti-slip rubber sleeve is fitted at the center of the grip plate.
[0012] (III) Beneficial Effects
[0013] The advantages of this invention compared to the prior art are as follows: the sensor body to be tested is placed under the cover, the lifting assembly is operated, and the weight of each hammer is simultaneously pressed down on each position of the sensor body by the fall rope. The weight of each hammer is the same. The measurement data of the sensor body is used to determine whether there is a fault in the sensor body that prevents accurate pressure detection.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] Example 1
[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a pressure sensor experimental device includes a sensor body 1, a lifting assembly, and a cover 2 that cooperates with the sensor body 1. Corner pads 3 are glued to the four corners of the bottom of the cover 2. At least one guide cylinder 9 is provided inside the cover 2 and is evenly arranged. A drop rope 7 is inserted into each guide cylinder 9. A pressure hammer 8 that cooperates with the sensor body 1 is provided at the lower end of each drop rope 7.
[0022] With the above structure, the pressure hammer 8 can press down on the sensor body 1. The specific structure for driving each pressure hammer 8 to rise and fall simultaneously is as follows:
[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the lifting assembly drives each pressure hammer 8 to rise and fall simultaneously. The lifting assembly includes a lifting plate 6 fixedly connected to the upper end of each fall rope 7. Insert rods 5 are fixedly connected to the four corners of the lower end of the lifting plate 6. The cover shell 2 is provided with slots 4 that cooperate with the insert rods 5. The upper end of the lifting plate 6 is provided with a grip plate 10. The center position of the grip plate 10 is fitted with an anti-slip rubber sleeve to facilitate gripping the center position of the grip plate 10.
[0024] Through the above structure, the lifting assembly can drive the pressure hammer 8 to rise and fall.
[0025] Example 2
[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the grip plate 10 is provided with a level 11 arranged opposite to each other. The two levels 11 are symmetrical about the center position of the grip plate 10. The lower end of the lifting plate 6 is fixedly connected to a guide plate 13. The cover shell 2 is provided with a guide groove 12 that cooperates with the guide plate 13.
[0027] The above structure facilitates the smooth lifting and lowering of the lifting plate 6, and the cooperation between the guide plate 13 and the guide groove 12 can also improve the stability of the lifting and lowering of the lifting plate 6.
[0028] In the specific implementation of this utility model, when conducting experimental testing on the sensor body, the sensor body is placed on a flat surface, and then the cover is placed on the sensor body. When placing the cover, the cover is kept horizontal, and the lifting plate is pulled upward so that the pressure hammer moves away from the sensor body. After the cover is placed, the middle part of the grip plate is grasped and slowly moved downward. The insertion rod will move downward in the slot, and the drop rope and pressure hammer will also move downward until the pressure hammer contacts the sensor body. During the downward movement of the lifting plate, the stability of the lifting plate during descent can be improved with the cooperation of the guide plate and the guide groove. The levelness of the lifting plate can be easily maintained by observing the reading of the level instrument.
[0029] After each pressure hammer contacts the sensor body, the sensor body can detect the pressure and display the value. If the value at a certain position differs too much from other values, there may be a fault at that position on the sensor body, and maintenance is required.
