Description

Technical Field

[0001] This utility model belongs to the field of sensor testing technology, specifically a test chamber device for sensors in high and low temperature environments. Background Technology

[0002] The test chamber for high and low temperature environments of sensors is a device specifically designed to simulate the working performance and stability of sensors under extreme temperature environments. This test chamber is mainly used to perform performance tests on sensors under high and low temperature environments to ensure the stability and accuracy of sensors under different temperature conditions. By simulating extreme temperature environments, the working ability of sensors under harsh conditions can be evaluated, thereby providing a strong guarantee for their reliability in practical applications. The test chamber includes a heater and a cooler. By precisely controlling the working status of the heater and cooler, rapid rise and fall and stable control of the temperature inside the chamber can be achieved.

[0003] In existing technologies, sensors are typically fixed inside a test chamber, and then the heater or cooler inside the test chamber is activated to perform performance tests on the sensors under high and low temperature environments. However, when two sensors need to be tested, one sensor must first be fixed inside the test chamber for testing, and after testing, it must be disassembled before the other sensor is fixed inside the test chamber for testing. This makes the operation cumbersome and results in low testing efficiency for the sensors. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a test chamber device for high and low temperature environments of sensors, comprising a test chamber body, wherein a partition is fixedly installed in the middle of the interior of the test chamber body, two openings are symmetrically provided on the top of the test chamber body, and an adjustment mechanism is provided on the test chamber body;

[0006] The adjustment mechanism includes a support plate located above the test chamber. A sleeve plate is provided above the support plate. A rotary motor is fixedly installed at the bottom of the sleeve plate. A rotating shaft is fixedly connected to the rotary motor.

[0007] Preferably, a sealing ring is fixedly installed at the bottom of each of the two top plates, and both sealing rings are in contact with the top of the test chamber. The inner diameter of each sealing ring is equal to the inner diameter of the two openings.

[0008] Preferably, a side plate is fixedly installed on the outside of the test chamber, and an L-shaped rod is fixedly connected between the top of the side plate and the outside of the test chamber. A fixing plate is fixedly sleeved on the outside of the L-shaped rod, and the fixing plate is fixed to the outside of the test chamber. A lifting plate located between the side plate and the fixing plate is movably sleeved on the outside of the L-shaped rod. Two connecting columns are symmetrically fixedly connected between the top of the lifting plate and the top of the support plate. Both connecting columns pass through the fixing plate and are movably connected to the fixing plate. A sleeve plate is fixedly sleeved on the outside of the two connecting columns.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, by setting a partition inside the test chamber, enables two sensors to be tested separately under high temperature and low temperature environments in two separate cavities inside the test chamber. The cooperation between the rotary motor and the rotating shaft, as well as the U-shaped plate and the top plate, facilitates the rotation of the two mounting brackets. The cooperation between the lifting motor, screw, screw sleeve, lifting plate, L-shaped round rod and connecting column facilitates the longitudinal movement of the two mounting brackets by the support plate, thereby facilitating the switching of the two sensors and improving the testing efficiency of the sensors.

[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 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.

[0024] Example 1, by Figure 1-2 The present invention relates to a test chamber device for high and low temperature environments of sensors, including a test chamber 1, a partition 4 fixedly installed in the middle of the interior of the test chamber 1, two openings 3 symmetrically provided on the top of the test chamber 1, an adjustment mechanism 2 provided on the test chamber 1, and the partition 4 dividing the interior of the test chamber 1 into two cavities, with a heater and a cooler respectively installed in the two cavities.

[0025] Specifically, by Figure 3-4The adjustment mechanism 2 includes a support plate 201 located above the test chamber 1. A sleeve plate 202 is positioned above the support plate 201. A rotary motor 2016 is fixedly mounted on the bottom of the sleeve plate 202. A rotating shaft 2013 is fixedly connected to the rotary motor 2016. A U-shaped plate 2012 is fixedly connected to the bottom end of the rotating shaft 2013. The rotating shaft 2013 passes through the support plate 201 and is rotatably connected to it. Two top plates 203 are symmetrically fixedly connected to the bottom of the U-shaped plate 2012. The two top plates 203 are respectively located at... Above the two openings 3, mounting brackets 2014 are fixedly installed on the bottom of the two top plates 203. Two sensors are fixed to the two mounting brackets 2014 respectively. The two mounting brackets 2014 pass through the two openings 3 and are located inside the test chamber 1. Sealing rings 2015 are fixedly installed on the bottom of the two top plates 203. Both sealing rings 2015 are in contact with the top of the test chamber 1, and the inner diameter of both sealing rings 2015 is equal to the inner diameter of the two openings 3. By setting the sealing rings 2015, the openings 3 can be... To ensure the airtightness of the test chamber 1, a side plate 204 is fixedly installed on the outside of the test chamber 1. An L-shaped rod 208 is fixedly connected between the top of the side plate 204 and the outside of the test chamber 1. A fixing plate 2010 is fixedly sleeved on the outside of the L-shaped rod 208, and the fixing plate 2010 is fixed to the outside of the test chamber 1. A lifting plate 207 located between the side plate 204 and the fixing plate 2010 is movably sleeved on the outside of the L-shaped rod 208. The top of the lifting plate 207 is aligned with the top of the support plate 201. The fixed connection has two connecting columns 2011, both of which penetrate the fixed plate 2010 and are movably connected to the fixed plate 2010. The sleeve plate 202 is fixedly sleeved on the outside of the two connecting columns 2011. The top of the side plate 204 is fixedly installed with a lifting motor 205. The lifting motor 205 is fixedly connected with a screw 209. The top of the screw 209 is rotatably connected to the bottom of the fixed plate 2010. The outside of the screw 209 is threaded with a screw sleeve 206. The lifting plate 207 is fixed to the outside of the screw sleeve 206.

[0026] In operation, when the rotary motor 2016 is started, it drives the rotating shaft 2013 to rotate, which in turn drives the U-shaped plate 2012 to rotate. Then, the two top plates 203 drive the two mounting brackets 2014 to rotate, achieving the circumferential rotation of the two sensors. When the lifting motor 205 is started, it drives the screw 209 to rotate, which drives the lifting plate 207 to slide along the L-shaped rod 208 through the screw sleeve 206. Then, the two connecting columns 2011 drive the support plate 201 to move longitudinally, which in turn drives the two mounting brackets 2014 to move longitudinally, achieving the longitudinal movement of the two sensors. After the two sensors have completed their performance tests in the two chambers under high and low temperature environments, the two sensors are raised to the outside of the test chamber 1 to switch their rotational positions. Then, the two sensors are lowered and enter the two chambers to perform performance tests, thereby enabling the two sensors to quickly perform performance tests under high and low temperature environments and improving testing efficiency.

[0027] Specifically, by Figure 5 As shown, two top rods 2018 are symmetrically fixedly connected to the top of the U-shaped plate 2012. The top of each top rod 2018 is provided with a ball bearing 2019 located at the bottom of the support plate 201. A positioning post 2017 is fixedly connected to the top of the U-shaped plate 2012. Two positioning blocks 2020 are symmetrically fixedly connected to the outer side of the support plate 201. The positioning post 2017 abuts against one of the positioning blocks 2020.

[0028] In use, when the U-shaped plate 2012 rotates, the two push rods 2018 drive the two balls 2019 to roll at the bottom of the support plate 201, ensuring the stability of the U-shaped plate 2012 during rotation. A positioning post 2017 is set on the top of the U-shaped plate 2012, and two positioning blocks 2020 are symmetrically arranged on the outside of the support plate 201. When the positioning post 2017 abuts against one of the positioning blocks 2020, it rotates to abut against the other positioning block 2020, thereby enabling the U-shaped plate 2012 to rotate 180°, thus limiting the rotation angle of the U-shaped plate 2012 and facilitating the quick passage of the mounting bracket 2014 through the opening 3.
