Description

Technical Field

[0001] This utility model relates to the field of protective device technology, specifically to a protective device for automotive sensors. Background Technology

[0002] Automotive gas sensors are key components in automotive electronic control systems, used to monitor engine exhaust gas composition, in-vehicle air quality, and other factors. Their performance directly affects a vehicle's power, fuel economy, and environmental friendliness. Gas sensors typically consist of a sensing element, a conversion element, and a measurement circuit. The sensing element directly detects the presence and concentration changes of the gas being measured and converts it into an electrical signal. The conversion element further amplifies, converts, and processes the electrical signal output by the sensing element. The measurement circuit measures and displays the converted electrical signal, or directly transmits the signal to the vehicle's electronic control unit.

[0003] The protective device for an automotive gas sensor consists of a first protective shell, a second protective shell, and a filter. The first and second protective shells enclose the sensor and are connected by bolts. The filter is connected to the sensor via a flange. The filter needs to be disassembled for cleaning after a period of use, and the protective shell needs to be replaced after use. However, disassembling the protective shell and filter requires specific disassembly and assembly tools, which affects disassembly and assembly efficiency and thus work efficiency. Furthermore, if the disassembly and assembly tools bump into the sensor surface during use, they may damage the sensor. Improvements should be made to address these issues.

[0004] Therefore, a protective device for automotive sensors is proposed. Utility Model Content

[0024] like Figures 1 to 4As shown, a protective device for an automotive sensor includes a sensor body 1, a filter screen 3, a first protective shell 5, and a second protective shell 6. A sleeve 2 is fixedly provided at one end of the sensor body 1, and the filter screen 3 is adapted to the sleeve 2. Embedding grooves are provided on both sides of the filter screen 3. A limiting mechanism 4 is provided on the surface of the sleeve 2 to confine the filter screen 3 within the sleeve 2. A connecting mechanism 7 is provided on the surfaces of the first protective shell 5 and the second protective shell 6 to connect them. The first and second protective shells 5 and 6 are adapted to the sensor body 1. Specifically, the first and second protective shells 5 and 6 are placed on opposite sides of the sensor body 1, and then the first and second protective shells 5 and 6 are closed. The first protective shell 5 and the second protective shell 6 are closed, thus enclosing the sensor body 1 and providing protection for it. After the first protective shell 5 and the second protective shell 6 are closed, the connecting mechanism 7 can quickly connect the first protective shell 5 and the second protective shell 6, thereby locking them in place. The filter screen 3 can filter particulate matter in the exhaust gas, and the limiting mechanism 4 can limit the filter screen 3 to the inside of the sleeve 2, thus enabling the installation of the filter screen 3. This device allows for convenient disassembly and assembly of the first protective shell 5, the second protective shell 6, and the filter screen 3 without the need for disassembly and assembly tools, thereby improving work efficiency and avoiding damage to the sensor body 1 when using disassembly and assembly tools, thus achieving protection for the sensor body 1.

[0025] like Figure 2 , Figure 3 As shown, the limiting mechanism 4 includes a guide rail 401. The guide rail 401 is fixedly mounted on the surface of the sleeve 2. A slider 402 is slidably mounted on the inner wall of the guide rail 401. A first spring 403 is fixedly mounted on the opposite side of one side wall of the slider 402 and the inner side wall of the guide rail 401. An embedding block 404 is fixedly mounted on the bottom end of the slider 402. A slot 405 is opened on the surface of the sleeve 2, and the embedding block 404 is adapted to the slot 405 and the embedding groove. Specifically, when installing the filter screen 3, the embedding block 404 is pulled. When the embedding block 404 moves to the outside of the sleeve 2, the filter screen 3 is placed inside the sleeve 2. The movement of the embedding block 404 causes the slider 402 to slide, thereby squeezing the first spring 403. When the embedding groove corresponds to the slot 405, the embedding block 404 is released. At this time, under the action of the elastic force of the first spring 403, the slider 402 is reset, thereby embedding the embedding block 404 into the embedding groove, thus realizing the installation of the filter screen 3.

[0026] like Figure 2 , Figure 3As shown, the guide rail 401 and the embedding block 404 are provided in two sets, and the two sets of embedding blocks 404 are T-shaped. Specifically, the two sets of embedding blocks 404 can be embedded into the embedding grooves on both sides of the filter screen 3 respectively, thereby limiting the installation of the filter screen 3. The T-shaped arrangement of the embedding block 404 makes it easy to pull it.

[0027] like Figure 1 , Figure 4 As shown, the connecting mechanism 7 includes a first fixing block 701 and a second fixing block 708. The first fixing block 701 is fixedly mounted on the surface of the first protective shell 5, and the second fixing block 708 is fixedly mounted on the surface of the second protective shell 6. A cavity 702 is formed on the surface of the first fixing block 701, and a second spring 703 is fixedly mounted inside the cavity 702. A shaft 704 is fixedly mounted on the other end of the second spring 703, and the shaft 704 is slidably installed with the inner wall of the cavity 702. A rotating block 705 is rotatably mounted on the other end of the shaft 704. A rectangular slot 706 and a rectangular groove 707 are respectively formed on the surface of the second fixing block 708. Specifically... During the closing process of the first protective shell 5 and the second protective shell 6, the rotating block 705 passes through the rectangular slot 706. After the first protective shell 5 and the second protective shell 6 are closed, the rotating block 705 is located on the other side of the second fixed block 708. At this time, the rotating block 705 is pulled and rotated, thereby causing the shaft 704 to move, which in turn stretches the second spring 703. When the rotating block 705 rotates to correspond with the rectangular groove 707, the rotating block 705 is released. Under the action of the elastic force of the second spring 703, the rotating block 705 is reset, thereby allowing the rotating block 705 to be embedded in the interior of the rectangular groove 707, thus completing the connection between the first protective shell 5 and the second protective shell 6.

[0028] like Figure 1 , Figure 4 As shown, the rectangular slot 706 and the rectangular groove 707 are arranged in a cross shape, and the rectangular groove 707 is adapted to the rotating block 705. Specifically, when the rotating block 705 is embedded in the interior of the rectangular groove 707, the inner wall of the rectangular groove 707 can fit against the surface of the rotating block 705, and the rectangular groove 707 can limit the rotation of the rotating block 705.

[0029] like Figure 1 , Figure 4 As shown, the internal space of the rectangular slot 706 is larger than the volume of the rotating block 705, and the surface of the rotating block 705 is provided with a rubber layer; specifically, the rotating block 705 will not collide with the inner wall of the rectangular slot 706 when it passes through the rectangular slot 706, and the rubber layer on the surface of the rotating block 705 can facilitate the pulling of the rotating block 705 during use.

[0030] In summary: The first protective shell 5 and the second protective shell 6 are placed on both sides of the sensor body 1 and face each other. When the first protective shell 5 and the second protective shell 6 are closed, they enclose the sensor body 1, thus protecting it. After the first protective shell 5 and the second protective shell 6 are closed, they can be quickly connected by the connecting mechanism 7, thereby locking them in place. The filter screen 3 filters particulate matter in the exhaust gas, and the limiting mechanism 4 confines the filter screen 3 inside the sleeve 2, thus enabling its installation. This device allows for convenient disassembly and assembly of the first protective shell 5, the second protective shell 6, and the filter screen 3 without the need for tools, improving work efficiency and preventing damage to the sensor body 1 when using tools, thus protecting the sensor body 1.
