Description

Technical Field

[0002] Powered industrial vehicle sensor testing refers to the inspection and evaluation of various sensors installed on powered industrial vehicles, including speed sensors, pressure sensors, temperature sensors, oxygen sensors, acceleration sensors and many other types of sensors. With the help of specific test equipment and methods, it is verified whether these sensors can accurately collect and transmit relevant data information. For example, the purpose of speed sensor testing is to ensure that it can accurately measure the speed of the vehicle; pressure sensor testing is used to confirm the accuracy of its measurement of pressure values ​​such as brake system pressure or tire pressure; temperature sensor testing needs to ensure that it can correctly reflect the actual temperature conditions of different parts of the vehicle. Vehicle sensor testing is extremely It is very important. It can not only detect possible faults or performance degradation of sensors in time, thereby ensuring the normal operation and safety of the vehicle, but also provide a strong basis for vehicle maintenance and optimize the performance and reliability of the vehicle. At present, acceleration sensors play many key roles in vehicles. On the one hand, they can be applied to the vehicle's safety system, such as detecting the acceleration changes during a collision, so as to trigger airbags and other protective devices in time to ensure the safety of passengers. On the other hand, in the vehicle's dynamic control system, such as the anti-lock braking system (ABS), the electronic stability control system (ESP), etc., the acceleration sensor can provide real-time acceleration data, and the auxiliary system can more accurately adjust the vehicle's braking and driving stability.

[0003] The Chinese patent with the publication number of "CN219266334U" discloses an acceleration sensor pressure resistance detection device, which is arranged at the lower end of the acceleration sensor pressure resistance detection block, and a device is placed at the lower part of the acceleration sensor pressure resistance detection block. The device is placed at the lower part of the anti-skid bottom block and is fixedly connected to the acceleration sensor pressure resistance detection block through an electric push rod. There is also a movable block, which is arranged below the device placement anti-skid bottom block, and a pressure sensor is installed at the lower end of the movable block. In addition, a numerical display is arranged at the upper end of one side of the acceleration sensor pressure resistance detection block, and the pressure sensor is electrically connected to the numerical display. This acceleration sensor pressure resistance detection device can make the numerical display more sensitive through the careful design of the pressure sensor, and the combined design of the pressure sensor and the numerical display can effectively facilitate a more in-depth and comprehensive understanding of the pressure resistance of the sensor;

[0004] However, in actual use, the overall structure of the above-mentioned device is relatively simple. After completing the positioning and clamping, it is not convenient to flip and adjust the positioned sensor. In the specific detection process, it is impossible to detect the top and bottom of the vehicle sensor, and the overall detection operation is relatively inconvenient. At the same time, it lacks the detection of the sensor's anti-seismic performance during the detection process. It should be noted that when the sensor is used in a vehicle, it usually generates a large amplitude of vibration during the driving process of the vehicle, so it is extremely important to test its anti-seismic performance. It can be seen that the test device involved in the existing technical means has certain defects and shortcomings, and it is urgently needed to improve its design. Utility Model Content

This design not only improves the efficiency and stability of the drive, but also ensures the synchronous movement of the two screw rods 862, thereby ensuring the accuracy and consistency of positioning. At the same time, this transmission method has a simple structure, reliable operation, and is easy to maintain and control. Through the cooperation of the second motor 8651, the transmission pulley 8653, and the transmission belt 8654, the positioning component 86 can quickly and accurately adjust the position to meet the positioning requirements of different sensors.

The mounting holes 9 can facilitate the installation of the base 1, and the mounting holes 9 are countersunk holes, which can hide the ends of the bolts, thereby improving the security and installation stability.

[0033] Principle and advantages of use: By setting the temperature and humidity adjustment mechanism 6, the positioning mechanism 8 can assist in positioning the sensor to be detected during use of the device. When positioning is completed, it is only necessary to close the sealing door 3, and then start the telescopic cylinder 4 to operate. The operation of the telescopic cylinder 4 can drive the pressure sensor 5 to move down and contact the sensor to be detected, thereby causing the sensor as a whole to be compressed, and the overall pressure resistance of the detector can be tested. In the detection process, if it is necessary to test the anti-seismic performance, the telescopic cylinder 4 can be started to shrink and move upward, and then the electric push rod 82 can be started to reciprocate and move. The reciprocating movement of the electric push rod 82 can push the clamped and positioned sensor. As the electric push rod 82 moves up and down and cooperates with the reciprocating and telescopic movement of the telescopic spring 832, the positioned sensor can be placed in a high vibration state, which can assist in simulating the detection of the anti-seismic performance of the positioned sensor, and improve the overall detection performance and functionality of the device.

[0034] By setting the positioning mechanism 8, during the use of the device, the sensor for the required positioning detection can be placed on the top of the electric push rod 82. At this time, the sensor can be moved between the inner sides of the two limit frames 864 by the operation of the electric push rod 82. At this time, by starting the second motor 8651, the second motor 8651 drives a screw rod 862 to rotate. When the screw rod 862 rotates, the transmission pulley 8653 at the other end also rotates. The transmission pulleys 8653 are connected by a transmission belt. Therefore, as the screw rod 862 rotates, the two transmission pulleys 8653 can be driven to rotate synchronously. When the two transmission pulleys 8653 rotate, the sliders 863 inside the frame 861 can be driven to slide relative to each other. The sliding displacement of 863 can drive the two limit frames 864 to slide relative to each other. The sliding displacement of the two limit frames 864 can flexibly adjust to clamp sensors of different sizes, so that the device can flexibly adapt to clamp sensors of different sizes and models, which can improve the overall adaptability of the device. In addition, during the detection process, the humidifier 61 and the electric heating tube 63 can be started as needed. The humidifier 61 can increase the humidity inside the chassis 2. At the same time, the operation of the electric heating tube 63 can increase the humidity inside the chassis 2, so that the device can increase the temperature and humidity inside the chassis 2, so that the device can flexibly adapt to the detection performance of different temperatures and humidity, facilitate the detection and use of the device, and improve the overall detection accuracy and adaptability of the device.
