Description

Technical Field

[0001] This utility model relates to a gas detection structure, specifically a gas detection structure for rapid detection by an automotive air quality sensor. Background Technology

[0002] Automotive air quality sensors are mainly used in automotive air conditioning systems and have extremely high detection sensitivity for some high-level pollutants, such as carbon monoxide, nitrogen dioxide, and ammonia.

[0003] Patent CN211741211U discloses an automated detection device for automotive air quality sensors. This device connects the air outlet on a cover plate to the gas detection interface of the air quality sensor under test. After the cover plate is tightened, a complete seal is achieved, and detection gases such as air, nitrogen dioxide, ammonia, and carbon monoxide are introduced. Finally, a cylinder and other drive mechanisms are activated, causing a lifting platform to rise and insert a metal probe into the air quality sensor under test. However, during the process of closing the cover plate, it is difficult to ensure that the air outlet on the detection cover plate fully contacts the gas detection interfaces of all the air quality sensors under test, thus compromising the detection quality of the air quality sensors. Utility Model Content

This detection structure places the air quality sensor on a support plate and presses the air quality sensor with a clamping mechanism, ensuring accurate connection between the air passage and the inlet of the air quality sensor, as well as accurate connection between the electrical connection terminal of the air quality sensor and the power-on mechanism, thus guaranteeing the detection quality of the sensor.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A gas detection structure for rapid detection by an automotive air quality sensor includes:

[0007] A rotating disk, on which a support plate is provided to support an air quality sensor;

[0008] A bracket is provided on the side of the rotating disk;

[0009] A clamping mechanism is slidably connected to the bracket and disposed directly above the support plate to clamp the air quality sensor placed on the support plate;

[0010] An energizing mechanism is slidably connected to the bracket and disposed directly below the support plate to energize the air quality sensor placed on the support plate.

[0011] A gas delivery mechanism is provided on the side of the support plate. The gas delivery mechanism includes a front and rear moving cylinder provided on the bracket, an air passage provided at the output end of the front and rear moving cylinder, and connectors spaced apart on the air passage. The connectors are directly opposite the gas detection inlet of the air quality sensor.

[0012] Furthermore, the clamping mechanism includes a clamping cylinder mounted on the bracket, a pressure plate mounted on the output end of the clamping cylinder and slidably connected to the bracket, and a plurality of clamping columns spaced apart on the pressure plate, the clamping columns being located directly above the air quality sensor.

[0013] Furthermore, the clamping column is an elastic column.

[0014] Furthermore, the pressure plate is provided with reinforcing ribs.

[0015] Furthermore, the power-on mechanism includes a lifting cylinder mounted on the bracket, a lifting plate mounted on the output end of the lifting cylinder and slidably connected to the bracket, and a plurality of metal probes spaced apart on the lifting plate, the metal probes being located directly below the air quality sensor.

[0016] Furthermore, the support plate includes two rows of spaced-apart storage holes, and the air quality sensor is placed in the storage holes.

[0017] Furthermore, the storage hole is a square hole or a round hole.

[0018] Furthermore, in the two rows of spaced-apart storage holes, the storage holes closer to the bracket are lower than the storage holes farther away from the bracket.

[0020] Furthermore, a pair of slide rails are provided on the side of the bracket near the rotating disk.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] (1) This utility model provides a gas detection structure for rapid detection of automotive air quality sensor. The detection structure places the air quality sensor on a support plate and presses the air quality sensor with a pressing mechanism, which ensures the accurate connection between the air passage connector and the air quality sensor inlet and the accurate connection between the air quality sensor electrical connection terminal and the power supply mechanism, thus ensuring the detection quality of the sensor.

[0023] (2) This utility model provides a gas detection structure for rapid detection of automotive air quality sensors. The detection structure uses a clamping column located directly above the air quality sensor to clamp each air quality sensor. In particular, the clamping column can be an elastic column, so that the pressing process is a highly controllable and uniform force application process, ensuring that the applied pressure can be evenly distributed on the surface of the sensor. This uniform pressure can effectively overcome problems such as loosening or poor contact that may occur during the installation of the sensor, so that each air quality sensor can be tightly fixed in its corresponding position, thereby ensuring the accurate connection of the subsequent air passage connector to the air quality sensor inlet and the accurate connection of the air quality sensor electrical connection terminal to the metal probe of the power-on mechanism, thus ensuring the accuracy and reliability of the detection data.

However, the scope of protection of the present invention is not limited to the following embodiments.

[0027] Example

[0028] This embodiment provides a gas detection structure for rapid detection using an automotive air quality sensor. See the specific structure below. Figure 1 ,include:

[0029] A rotating disk 1, on which a support plate 2 is provided to support an air quality sensor;

[0030] The bracket 3 is disposed on the side of the rotating disk 1;

[0031] A clamping mechanism is slidably connected to the bracket 3 and disposed directly above the support plate 2 to clamp the air quality sensor placed on the support plate 2;

[0032] An energizing mechanism is slidably connected to the bracket 3 and disposed directly below the support plate 2 to energize the air quality sensor placed on the support plate 2.

[0033] The gas delivery mechanism is located on the side of the support plate 2. The gas delivery mechanism includes a front and rear moving cylinder 4 located on the bracket 3, an air passage 5 located at the output end of the front and rear moving cylinder 4, and a connector 6 spaced apart on the air passage 5. The connector 6 is directly opposite the gas detection inlet of the air quality sensor.

[0034] In this embodiment, the clamping mechanism includes a clamping cylinder 7 mounted on the bracket 3, a pressure plate 8 mounted on the output end of the clamping cylinder 7 and slidably connected to the bracket 3, and a plurality of clamping columns 9 spaced apart on the pressure plate 8, the clamping columns 9 being located directly above the air quality sensor. Preferably, the clamping columns 9 are elastic columns; the pressure plate 8 is provided with reinforcing ribs 10.

[0035] In this embodiment, the power-on mechanism includes a lifting cylinder 11 mounted on the bracket 3, a lifting plate 12 mounted on the output end of the lifting cylinder 11 and slidably connected to the bracket 3, and a plurality of metal probes spaced apart on the lifting plate 12, wherein the metal probes are located directly below the air quality sensor.

[0036] In this embodiment, the support plate 2 includes two rows of spaced-apart storage holes, and the air quality sensor is placed in the storage holes. Preferably, the storage holes are square or circular.

[0037] In this embodiment, the storage holes closer to the bracket 3 are lower than the storage holes farther away from the bracket 3 in the two rows of spaced-apart storage holes.

[0038] In this embodiment, the air inlet of the air passage 5 is connected to an air source.

[0039] In this embodiment, a pair of slide rails 13 are provided on the side of the bracket 3 near the rotating disk 1.

[0040] Working principle:

[0041] The detection structure in this embodiment uses a clamping column 9 located directly above the air quality sensor to clamp each air quality sensor. In particular, the clamping column 9 can be an elastic column, making the pressing process highly controllable and uniform in force application. This ensures that the applied pressure is evenly distributed on the surface of the sensor. This uniform pressure effectively overcomes problems such as loosening or poor contact that may occur during sensor installation, allowing each air quality sensor to be tightly fixed in its corresponding position. This, in turn, ensures the accurate connection of the connector 6 of the subsequent air passage 5 to the inlet of the air quality sensor and the accurate connection of the electrical connection terminal of the air quality sensor to the metal probe of the power-on mechanism, thereby ensuring the accuracy and reliability of the detection data.
