Description

Technical Field

[0001] The present application relates to the technical field of automobile exhaust gas detection, and in particular to an automobile exhaust gas detector. Background Art

[0002] Automobile inspection is an examination to determine the technical condition or working ability of the automobile. During the use of the automobile, as the use time increases (or the mileage increases), its parts gradually wear, corrode, deform, age, and the lubricant deteriorates, causing the clearance of the mating pairs to become larger, causing loose movement, vibration, noise, and air, water and oil leakage, resulting in a decline in the technical performance of the automobile. The core of automobile maintenance work (or automobile care work) is to "maintain" the integrity of the automobile's technical condition.

[0003] The automobile exhaust gas detector is an instrument used to detect the content of various gas elements in automobile exhaust gas. In the prior art, when the automobile exhaust gas detector detects automobile exhaust gas, the user manually places the exhaust gas collection end of the automobile to the mouth of the automobile exhaust emission pipe to collect the automobile exhaust gas, thereby detecting the automobile exhaust gas. After the detection is completed, the automobile exhaust gas detector is stored to facilitate the next automobile exhaust gas detection. However, in the prior art, when using the automobile exhaust gas detector to detect automobile exhaust gas, the user needs to manually take the automobile exhaust gas detector, and after use, it needs to be stored again, which is not convenient to use. Utility Model Content

[0004] In order to facilitate the use of an automobile exhaust gas detector to detect vehicle exhaust gas, the present application provides an automobile exhaust gas detector.

[0005] The automobile exhaust gas detector provided in this application adopts the following technical solution:

[0006] A vehicle exhaust gas detector comprises a mounting seat, a clamping ring, a detection device and a clamping device, wherein the clamping device is mounted on one side of a vehicle exhaust pipe, the clamping ring is sleeved on the vehicle exhaust pipe, the clamping ring is connected to the clamping device, the clamping device is used to clamp the clamping ring to the vehicle exhaust pipe, the side of the clamping device facing away from the clamping ring is connected to the mounting seat, the detection device is connected to the mounting seat, and the detection device is used to detect exhaust gas discharged from the vehicle.

[0007] By adopting the above technical scheme, when using the automobile exhaust gas detector to detect automobile exhaust gas, the automobile exhaust gas detector can be installed on the automobile exhaust emission pipe through the clamping ring and the clamping device, and the automobile exhaust gas can be detected at any time when the automobile is driving or parked. The user does not need to take the automobile exhaust gas detector to detect the automobile exhaust gas when it is needed, which facilitates the use of the automobile exhaust gas detector to detect automobile exhaust gas.

[0008] Optionally, the clamping device includes a support plate, an abutting plate, a rotating plate, a first telescopic block and a second telescopic block. One side of the abutting plate is connected to the clamping ring. One end of the support plate is fixedly connected to the middle of the abutting plate. The middle of the rotating plate is hinged to the other end of the support plate. The first telescopic block and the second telescopic block are located between the abutting plate and the rotating plate. The first telescopic block and the second telescopic block are respectively located on both sides of the support plate. The first telescopic block and the second telescopic block can drive the rotating plate to rotate around the support plate.

[0009] By adopting the above technical solution, after the clamping device and the clamping ring act together to install the vehicle exhaust gas detector on the vehicle exhaust pipe, the inner wall of the clamping ring and the clamping device together abut against the outer wall of the vehicle exhaust pipe, and the relative position between the vehicle exhaust gas detector and the vehicle exhaust pipe is kept unchanged through friction. When the temperature of the vehicle exhaust pipe rises or falls, causing a change in the distance between the clamping ring and the vehicle exhaust pipe, the first telescopic block and the second telescopic block can drive the rotating plate to rotate, so as to ensure that there is sufficient friction between the inner wall of the clamping ring and the outer wall of the vehicle exhaust pipe, thereby reducing the probability of the vehicle exhaust gas detection device sliding on the vehicle exhaust pipe.

[0010] Optionally, both ends of the first telescopic block are respectively fixedly connected to one side of the rotating plate close to the clamping ring and one side of the abutting plate close to the clamping ring. One end of the second telescopic block is fixedly connected to the side of the abutting plate facing away from the clamping ring, and the other end of the second telescopic block abuts against the side of the rotating plate facing away from the clamping ring.

[0011] By adopting the above technical solution, when the temperature of the vehicle exhaust pipe drops, the first telescopic block and the second telescopic block decrease in volume due to the temperature drop. The first telescopic block drives the side of the rotating plate close to the clamping ring to rotate towards the abutting plate, and the second telescopic block contracts and separates from the rotating plate, reducing the influence on the rotating plate.

[0012] Optionally, clamping cylinders are sleeved on the side walls of the first telescopic block and the second telescopic block, and the bottom wall of the clamping cylinder is fixedly connected to the abutting plate.

[0013] By adopting the above technical solution, the volume change between the first telescopic block and the second telescopic block is concentrated in the direction of the rotating plate and the abutting plate through the clamping cylinder, thereby expanding the influence of the first telescopic block and the second telescopic block on the rotating plate and improving the sensitivity of the first telescopic block and the second telescopic block.

[0014] Optionally, the first telescopic block and the second telescopic block are made of the same material, and the thickness of the first telescopic block is less than the thickness of the second telescopic block.

[0015] By adopting the above technical solution, the expansion coefficients of the first expansion block and the second expansion block made of the same material are the same. Therefore, for the second expansion block with a larger volume, the volume change is greater when the temperature rises. Due to the effect of the clamping cylinder, the volume change of the second expansion plate in the direction towards the rotating plate is greater than the expanded volume of the first expansion plate. Therefore, the rotating plate is mainly affected by the second expansion plate, causing the rotating plate to rotate towards the clamping ring, making the clamping ring and the automobile exhaust pipe clamped more tightly.

[0016] Optionally, the first expansion block and the second expansion block are made of different materials, and the volume of the first expansion block expanding towards the rotating plate due to heat is smaller than the volume of the second expansion block expanding towards the rotating plate due to heat.

[0017] By adopting the above technical solution, for the first expansion block and the second expansion block made of different materials, since the expansion volume of the second expansion block in the direction of the rotating plate is greater than that of the first expansion block, after the temperature of the automobile exhaust pipe rises, the rotation of the rotating plate is mainly controlled by the second expansion block, causing the rotating plate to rotate towards the abutting plate, increasing the friction force between the clamping ring and the automobile exhaust pipe, and thus reducing the probability of the automobile exhaust gas detector moving on the automobile exhaust pipe.

[0018] Optionally, the detection device is fixedly connected to one side of the support plate and the abutting plate. The detection device includes a collection cylinder and an analyzer. The side wall of the collection cylinder is fixedly connected to the side wall of the support plate. The mouth of the collection cylinder is located at the mouth of the automobile exhaust pipe. The analyzer is communicated with the collection cylinder, and the analyzer is used to analyze the automobile exhaust gas in the collection cylinder.

[0019] By adopting the above technical solution, the automobile exhaust gas is collected by the collection cylinder and analyzed by the analyzer, thereby realizing the detection of the automobile exhaust gas.

[0020] Optionally, a fan is arranged in the collection cylinder, and the fan is used to drive the automobile exhaust gas to flow from the mouth of the collection cylinder to the analyzer.

[0021] By adopting the above technical solution, the gas flow rate in the collection cylinder is controlled by the fan, facilitating the analyzer to detect the automobile exhaust gas.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When detecting vehicle exhaust gas, the vehicle exhaust gas detector is clamped on the vehicle exhaust pipe through a clamping ring and a clamping device to form an integral body with the vehicle, so that the vehicle exhaust gas emission amount when the vehicle is driving or parked can be measured. Without the user having to take the vehicle exhaust gas detector when detecting the vehicle exhaust gas, it is convenient to use the vehicle exhaust gas detector to detect the vehicle exhaust gas;

[0024] 2. When the temperature of the vehicle exhaust pipe drops, the temperatures of the first expansion block and the second expansion block both drop accordingly. The volume reduction of the first expansion block drives the rotating plate to rotate towards the abutting plate in the direction of the clamping groove, so that the clamping ring clamps the vehicle exhaust pipe more tightly, reducing the probability of the vehicle exhaust gas detector rotating on the vehicle exhaust pipe;

[0025] 3. When the temperature of the vehicle exhaust pipe rises, the temperatures of the first expansion block and the second expansion block rise, and then drive the volumes of the first expansion block and the second expansion block to increase. Since the volume change range of the first expansion block is smaller than that of the second expansion block, the rotating block is mainly affected by the second expansion block. Therefore, the rotating block rotates along the direction of the rotating ring towards the abutting plate, reducing the probability of the vehicle exhaust gas detector rotating on the vehicle exhaust pipe.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following is a further detailed description of the present application in conjunction with the attached Figure 1-2 to further illustrate the present application in detail.

[0030] An embodiment of the present application discloses a vehicle exhaust gas detector.

[0031] Embodiment 1

[0032] Refer to Figure 1 and Figure 2A vehicle exhaust gas detector comprises a mounting base 1, a clamping ring 2, a detection device 3 and a clamping device 4, the clamping device 4 is clamped on one side of a vehicle exhaust pipe, the clamping ring 2 is sleeved on the vehicle exhaust pipe, the clamping ring 2 is provided with an opening, the side of the clamping ring 2 with the opening is detachably connected to the side of the clamping device 4 close to the vehicle exhaust pipe, the mounting base 1 is fixedly connected to the side of the clamping device 4 away from the clamping ring 2, the detection device 3 is connected to the mounting base 1, and the detection device 3 is used to detect the exhaust gas discharged from the vehicle.

[0033] When the automobile exhaust gas detector is used to detect automobile exhaust gas, the clamping ring 2 is tightly clamped on the automobile exhaust gas exhaust pipe through the clamping device 4, and the automobile exhaust gas discharged from the automobile exhaust gas exhaust pipe is detected through the detection device 3, thereby completing the detection of automobile exhaust gas. By clamping the automobile exhaust gas detector on the automobile exhaust gas exhaust pipe, it is integrated with the automobile to realize the detection of automobile exhaust gas, and the user does not need to take the automobile exhaust gas detector for detection when detecting automobile exhaust gas, which facilitates the automobile exhaust gas detector to detect automobile exhaust gas.

[0034] Reference Figure 1 and Figure 2 The clamping device 4 includes a support plate 41, an abutting plate 42, a rotating plate 43, a first telescopic block 44 and a second telescopic block 45. One side of the abutting plate 42 is bolted to one end of the opening of the clamping ring 2, one end of the support plate 41 is fixedly connected to the middle of the abutting plate 42, the middle of the rotating plate 43 is hinged to the other end of the support plate 41, one side of the rotating plate 43 is bolted to the other end of the opening of the clamping ring 2, the first telescopic block 44 and the second telescopic block 45 are located between the abutting plate 42 and the rotating plate 43, the first telescopic block 44 and the second telescopic block 45 are respectively located on both sides of the support plate 41, and the first telescopic block 44 and the second telescopic block 45 can drive the rotating plate 43 to rotate around the support plate 41 along the direction of the clamping ring 2 toward the abutting plate 42. The two ends of the first telescopic block 44 are respectively fixedly connected to the side of the rotating plate 43 close to the clamping ring 2 and the side of the abutment plate 42 close to the clamping ring 2. One end of the second telescopic block 45 is fixedly connected to the side of the abutment plate 42 away from the clamping ring 2, and the other end of the second telescopic block 45 abuts against the side of the rotating plate 43 away from the clamping ring 2.

[0035] When the clamping device 4 is working, the first telescopic block 44 and the second telescopic block 45 drive the rotating plate 43 to rotate around the support plate 41, so that the clamping ring 2 and the automobile exhaust pipe are clamped more tightly, thereby increasing the clamping force of the clamping ring 2 on the automobile exhaust pipe and reducing the probability that the automobile exhaust detector cannot detect automobile exhaust due to rotation on the automobile exhaust pipe.

[0036] The first telescopic block 44 and the second telescopic block 45 are made of the same material, and the thickness of the first telescopic block 44 is less than that of the second telescopic block 45. The side walls of the first telescopic block 44 and the second telescopic block 45 are abutted against a clamping cylinder 46, and the bottom end of the clamping cylinder 46 is fixedly connected to the top end of the abutting plate 42.

[0037] The first telescopic block 44 and the second telescopic block 45 made of the same material have the same thermal expansion rate. Therefore, the volume increase of the first telescopic block 44 and the second telescopic block 45 due to heat is only affected by the volume of the first telescopic block 44 and the second telescopic block 45 themselves. By abutting the clamping cylinder 46 against the side walls of the first telescopic block 44 and the second telescopic block 45, the direction of volume change of the first telescopic block 44 and the second telescopic block 45 is changed to the direction towards the rotating plate 43. Thus, when the first telescopic block 44 and the second telescopic block 45 expand due to heat, the expansion amount of the second telescopic block 45 in the direction towards the rotating plate 43 is more. Therefore, the rotation of the rotating plate 43 is mainly affected by the second telescopic block 45. Furthermore, the rotating plate 43 rotates towards the abutting plate 42 along the direction of the clamping ring 2, making the connection between the clamping ring 2 and the automobile exhaust pipe tighter. When the first telescopic block 44 and the second telescopic block 45 contract due to cold, since the first telescopic block 44 is fixedly connected to the rotating plate 43 and the second telescopic block 45 is in abutment with the rotating plate 43, the contraction of the first telescopic block 44 will drive the rotation of the rotating plate 43, and the contraction of the second telescopic block 45 will gradually separate from the rotating plate 43. Thus, when the temperature decreases, the rotation of the rotating plate 43 is mainly controlled by the first telescopic block 44. Under the action of the first telescopic block 44, the rotating plate 43 rotates towards the abutting plate 42 along the direction where the clamping ring 2 is located, making the connection between the clamping ring 2 and the automobile exhaust pipe tighter.

[0038] Refer to Figure 1 and Figure 2 As shown in, the detection device 3 is fixedly connected to one side of the support plate 41 and the abutting plate 42. The detection device 3 includes a collection cylinder 31 and an analyzer 32. The side wall of the collection cylinder 31 is fixedly connected to the side wall of the support plate 41. The mouth of the collection cylinder 31 is located at the mouth of the automobile exhaust pipe. A blower 33 is arranged in the collection cylinder 31. The blower 33 is used to drive the automobile exhaust gas to flow from the mouth of the collection cylinder 31 to the analyzer 32. The analyzer 32 is communicated with the collection cylinder 31. The analyzer 32 is used to analyze the automobile exhaust gas in the collection cylinder 31.

[0039] When the detection device 3 works, the blower 33 is turned on, so that the automobile exhaust gas discharged from the automobile exhaust pipe flows into the collection cylinder 31 and passes through the analyzer 32. Then, the analyzer 32 analyzes the automobile exhaust gas discharged from the automobile exhaust pipe to obtain the emission situation of the automobile exhaust pipe.

[0040] The implementation principle of an automotive exhaust gas detector in an embodiment of this application is as follows: When using the automotive exhaust gas detector to detect automotive exhaust gas, the automotive exhaust gas emitter is installed on the automotive exhaust pipe through the clamping ring 2 and the clamping device, and the emission status of the automotive exhaust gas can be detected at any time during the driving process or when the vehicle is parked. Thus, it is not necessary for the user to hold the automotive exhaust gas emitter close to the automotive exhaust pipe for detection, facilitating the detection of automotive exhaust gas using the automotive exhaust gas detector.

[0041] Embodiment 2

[0042] Refer to Figure 1 , the difference between the second embodiment of this application and the first embodiment is that: The first expansion block 44 and the second expansion block 45 are made of different materials, the volumes of the first expansion block 44 and the second expansion block 45 are the same, and the volume of the first expansion block 44 expanding towards the rotating plate 43 when heated is smaller than the volume of the second expansion block 45 expanding towards the rotating plate 43 when heated.

[0043] The first expansion block 44 and the second expansion block 45 made of different materials regulate the expansion amounts of the first expansion block 44 and the second expansion block 45 with respect to the rotating plate 43 by selecting materials with different expansion coefficients. Thus, when the first expansion block 44 and the second expansion block 45 are heated, the rotation of the rotating plate 43 is mainly affected by the second expansion block 45, causing the rotating plate 43 to rotate towards the abutting plate 42 along the direction where the clamping ring 2 is located, and the clamping between the clamping ring 2 and the automotive exhaust pipe becomes tighter. When the temperatures of the first expansion block 44 and the second expansion block 45 decrease, the rotating plate 43 is mainly affected by the first expansion block 44, causing the rotating plate 43 to rotate towards the abutting plate 42 along the direction where the clamping ring 2 is located, and the clamping between the clamping ring 2 and the automotive exhaust pipe becomes tighter.

[0044] The above are all preferred embodiments of this application. Without restricting the protection scope of this application based on this, therefore: Any equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
