In use, the top cover of the movable housing is opened, the height of the sampling and detection components is adjusted using the folding and lifting assembly, and the sampling tube extends out of the opening at the top of the movable housing, connecting to the vehicle's exhaust pipe for sampling and detection. After use, the cover is closed to protect the components and accessories. The vehicle exhaust gas sampling and detection device provided by this utility model improves the portability and safety of automotive exhaust gas analysis equipment, enhances the protective performance and service life of the equipment, allows for outdoor operation in rainy weather to prevent the battery inside from getting wet and being electrocuted, avoiding damage to the equipment. It also solves the problem of difficulty in obtaining power in certain scenarios, facilitating on-site testing.

[0019] In an alternative embodiment, the folding and lifting assembly includes an electrically controlled scissor lift table supported on a drawer.

[0020] As can be seen from the above description, the sampling and detection components are stably raised and lowered by the electrically controlled scissor lift table, thereby flexibly adjusting the height of the equipment according to the application scenario.

[0021] In an optional embodiment, the sampling and detection component includes a main unit and a printer placed on an electrically controlled scissor lift table, with the battery, main unit, and printer connected in pairs.

[0022] In an optional embodiment, the sampling and detection accessories include a sampling probe, a speed sensor, an oil temperature sensor, and a power cord.

[0023] As can be seen from the above description, all the accessories are stored in drawers, making them convenient and safe to access.

[0024] In an optional embodiment, the bottom of the movable housing is equipped with casters.

[0025] As can be seen from the above description, the casters facilitate the flexible movement of the box.

[0026] In an optional embodiment, the side wall of the movable housing is provided with a telescopic pull rod.

[0027] As can be seen from the above description, the telescopic rod serves to facilitate lifting by the user.

[0028] In an optional embodiment, the bottom of the movable housing is provided with support legs.

[0029] As can be seen from the above description, the support legs serve to facilitate the movement of the box and to ensure its stable placement when stationary.

[0030] In an optional embodiment, the inner wall of the movable box is provided with sponge.

[0031] As can be seen from the above description, batteries and other components require special protection, and sponges play a role in reducing impact and vibration to prevent damage.

[0032] In an optional embodiment, the opening is provided with a slide rail, and the box cover includes two split-type cover plates that are slidably connected to the slide rail.

[0033] As can be seen from the above description, when opening the box lid, the two split lids are opened to both sides along the slide rail, making the operation convenient.

[0034] In an optional embodiment, the sampling tube has a notch on the side wall of the sampling port along the generatrix direction, and two or more notches are evenly arranged along the circumference of the sampling tube. The sampling port is connected to the vehicle exhaust pipe through a quick-connect clamp connector.

[0035] As described above, the quality of the connection between the vehicle's exhaust pipe and the sampling pipe directly affects the accuracy of the final test data during exhaust gas sampling. The industry commonly uses silicone tubing as an adapter. Silicone tubing has a certain degree of flexibility and good sealing properties. During use, it can be fixed to the vehicle's exhaust pipe and the exhaust gas sampling pipe with the help of pipe clamps, achieving a connection between the two pipes. However, silicone is a rubber product, and it is prone to aging and deformation after repeated use. Furthermore, under the high temperature of the exhaust pipe, the silicone tubing is easily degraded, producing odors and forming new gases, which can easily lead to deviations in the test data collection. To overcome the drawbacks of silicone tubing connections, another connection method is to use 304 stainless steel tubing. Steel tubing has good stability, is not easily deformed, and has good durability. However, as the model of the vehicle being tested changes, the diameter of the exhaust pipe outlet will also change accordingly, varying in size and shape (round or elliptical). Steel tubing has poor plasticity, which means that a new connecting pipe needs to be made for each test, resulting in higher costs.

[0036] To retain the advantages of 304 stainless steel tubing and avoid the disadvantages of silicone tubing, this invention uses stainless steel tubing as the sampling tube. Stainless steel tubing is advantageous due to its readily available material and stable chemical composition, but its disadvantage is poor plasticity. To allow the steel tube diameter to freely expand and contract, a 45mm diameter, 300mm long steel tube is cut vertically into eight sections, each 150mm long, with a 3mm diameter circle at the end of each cut. Cutting the circle into eight sections allows for free enlargement or reduction, and when encountering an elliptical exhaust pipe, it can be easily shaped into an elliptical form, thus perfectly fitting the exhaust pipe. A quick-connect clamp is made at the other end of the circle, and a similar quick-connect clamp is installed on the stainless steel sampling tube. The two joints are securely connected and sealed using a snap-fit ​​mechanism. This design improves the reliability of the connection between the automotive exhaust pipe and the sampling tube, ensuring the authenticity of the test data.

[0037] Please refer to Figures 1 to 4 As shown, Embodiment 1 of this utility model is: a vehicle exhaust gas sampling and detection device, including a movable housing. The housing shell is made of ABS synthetic resin to ensure shell strength, prevent damage, and effectively protect the contents. The inner cavity of the movable housing is divided into an upper chamber and a lower chamber by a drawer with a height of 150mm. The lower chamber has a height of 100mm and contains a 220V battery with a length of 320mm, a height of 75mm, and a width of 230mm. The drawer contains sampling and detection accessories. The upper chamber has a height of 300mm and contains a folding and lifting assembly. The sampling and detection assembly is mounted on the folding and lifting assembly and is connected to the battery. The top of the movable housing has an opening for the sampling tube of the sampling and detection assembly to extend out, and a cover is provided at the opening.

[0038] The folding and lifting assembly includes an electrically controlled scissor lift table supported on a drawer. The sampling and testing assembly includes a main unit measuring 357mm long, 260mm wide, and 157mm high, and a printer measuring 190mm long, 110mm wide, and 90mm high, placed on the electrically controlled scissor lift table.
