Description

Technical Field

[0001] This utility model relates to the field of air detection sensor technology, specifically a data transmission interface protection mechanism for an in-vehicle air detection device. Background Technology

[0002] The vehicle air quality monitoring system is used to monitor the air quality inside and outside the vehicle. It mainly consists of an air quality sensor (AQS). By detecting the concentration of pollutants such as PM2.5, TVOC, and CO2 in the air in real time, as well as parameters such as temperature and humidity, it automatically adjusts the air conditioning circulation mode to maintain the air quality inside the vehicle.

[0003] The aforementioned technologies have certain shortcomings in their application: the vehicle air quality sensor is mainly used to detect the air quality inside and outside the vehicle, and transmits the detected air quality data to the vehicle computer in real time through a plug and transmission line connected to the data interface. It automatically adjusts the air conditioning circulation mode to maintain the air quality inside the vehicle based on air factors. Since the plug is directly plugged into the data transmission interface, a protective structure needs to be added, mainly to prevent the plug from falling off due to bumps during vehicle operation.

[0004] To address this issue, the present invention provides a protective mechanism for the data transmission interface of an in-vehicle air detection device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a protective mechanism for the data transmission interface of an in-vehicle air detection device, thus solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a protective mechanism for the data transmission interface of an in-vehicle air detection device, including an in-vehicle air sensor and a connected data transmission line, a connector is installed at the bottom of the data transmission line, a control motherboard interface connected to an in-vehicle computer is plugged into the bottom of the connector, an anti-detachment component is installed on the outer wall of the connector to prevent the control motherboard interface and the connector from falling off, and a locking component for elastic snap-fit ​​is fixedly installed on the outer wall of the control motherboard interface; The locking assembly includes a triangular locking block set on the outer wall of the connector, and spring plates that can be elastically deformed are installed on the outer wall of the control motherboard interface and at the position corresponding to the triangular locking block. The outer wall of the spring plates is provided with a slot for fitting the triangular locking block, and the slot is locked and fixed to the triangular locking block. The anti-detachment component includes positioning rods fixedly installed on both sides of the bottom wall of the connector. Two anti-detachment seats are symmetrically arranged at the bottom of each positioning rod. A limiting area is formed between the two anti-detachment seats on the same positioning rod. Limiting rings are installed on both sides of the top wall of the control motherboard interface through uprights. The limiting rings are sleeved inside the limiting area of ​​the positioning rod to form a limiting and fixing effect.

[0007] With the above technical solution, after the connector is inserted into the control motherboard interface, the locking component and the anti-detachment component can quickly lock the connector and the control motherboard interface together. The installation method is simple and easy to operate. After installation, the connector and the control motherboard interface can transmit data stably to prevent detachment.

[0008] Furthermore, the bottom of the triangular block is inclined to facilitate the deformation of the spring sheet, and the top of the triangular block is horizontal to form a snap-fit ​​with the slot. The top wall of the spring sheet is fixedly equipped with an operating handle for pulling the spring sheet to deform and disengaging the slot from the snap-fit ​​state of the triangular block.

[0009] Through the above technical solution, after the triangular block is pressed down, it causes the spring plate to undergo elastic deformation, so that the triangular block can smoothly enter the slot to form a snap-fit ​​and complete the snap-fit ​​limit.

[0010] Furthermore, the inner edge of the anti-detachment seat is in a hollow state, and it will deform under pressure, allowing it to smoothly enter the interior of the limiting ring.

[0011] Through the above technical solution, the inner periphery of the anti-detachment seat will deform after being squeezed, and can smoothly enter the inner part of the limiting ring to complete the installation and limiting.

[0012] Furthermore, chamfers are provided on the outer edge of the anti-slip seat, and corresponding chamfers are provided at the contact positions of the limiting ring and the outer edge of the anti-slip seat. The chamfers on the limiting ring and the anti-slip seat fit together to form a limiting effect.

[0013] Through the above technical solution, after the anti-detachment seat enters the limiting area inside the limiting ring, the chamfer on the limiting ring and the anti-detachment seat are matched to form a limit.

[0014] Furthermore, the vehicle air sensor includes a base, with a connection terminal for connecting to the data transmission line mounted on the top of the base, and a fastening seat fixedly mounted on the top wall of the base at the position corresponding to the connection terminal.

[0015] With the above technical solution, the base is mainly used to support the entire vehicle air sensor component, and the data transmission line is installed and connected through the connector.

[0016] Furthermore, a control module is installed at the bottom of the base, and a locking device is installed on the bottom wall of the base at the position corresponding to the control module.

[0017] Through the above technical solution, the control module can receive and transmit the detection data measured by the control detection probe.

[0018] Furthermore, a detection probe connected to the control module is installed on the bottom wall of the base for detecting air quality.

[0019] The detection probe, based on the above technical solution, is mainly used for detecting air quality. Beneficial effects

[0020] This utility model provides a protective mechanism for the data transmission interface of an on-board air detection device. Compared with the prior art, it has the following advantages: (1) The data transmission interface protection mechanism of the vehicle air detection device, after the vehicle air sensor is installed, when the connector and the control motherboard interface are inserted, the anti-detachment component and the locking component intervene to ensure that the connector and the control motherboard interface are in a locked and limited state after the connector and the control motherboard interface are inserted. When the vehicle is moving, the connector and the control motherboard interface are prevented from falling off due to the bumps, so that the detection data transmission is always stable. This can increase the safe operation of the entire vehicle air sensor. At the same time, the anti-detachment component and the locking component are easy to install and connect. They can be directly aligned and pressed down. The whole installation method is simple and convenient to operate. Attached Figure Description

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0024] Please see Figures 1-4A protective mechanism for the data transmission interface of an in-vehicle air detection device includes an in-vehicle air sensor 1 and a connected data transmission line 2. A connector 3 is installed at the bottom of the data transmission line 2. A control motherboard interface 4 connected to an in-vehicle computer is plugged into the bottom of the connector 3. An anti-detachment component 5 is installed on the outer wall of the connector 3 to prevent the control motherboard interface 4 and the connector 3 from falling off. A locking component 6 for elastic snap-fit ​​is fixedly installed on the outer wall of the control motherboard interface 4. The locking assembly 6 includes a triangular locking block 61 disposed on the outer wall of the connector 3. A spring sheet 62 capable of elastic deformation is installed on the outer wall of the control motherboard interface 4 at a position corresponding to the triangular locking block 61. The outer wall of the spring sheet 62 is provided with a slot 63 for fitting the triangular locking block 61. The slot 63 is locked and fixed to the triangular locking block 61. The bottom of the triangular locking block 61 is inclined to facilitate the compression of the spring sheet 62 to cause deformation. The top of the triangular locking block 61 is horizontal to form a locking fit with the slot 63. An operating handle 64 is fixedly installed on the top wall of the spring sheet 62 for pulling the spring sheet 62 to deform and disengaging the slot 63 from the locked state of the triangular locking block 61. The anti-detachment component 5 includes positioning rods 51 fixedly installed on both sides of the bottom wall of the connector 3. Two anti-detachment seats 52 are symmetrically arranged at the bottom of each positioning rod 51. A limiting area 53 is formed between the two anti-detachment seats 52 located on the same positioning rod 51. Limiting rings 55 are installed on both sides of the top wall of the control motherboard interface 4 through uprights 54. The limiting rings 55 are sleeved inside the limiting area 53 of the positioning rod 51 to form a limiting fixation. The inner edge of the anti-detachment seat 52 is in a cavity state. After being squeezed, it will deform and smoothly enter the interior of the limiting ring 55. The outer edge of the anti-detachment seat 52 is chamfered. At the same time, the contact position between the limiting ring 55 and the outer edge of the anti-detachment seat 52 is also chamfered. The chamfers on the limiting ring 55 and the anti-detachment seat 52 are adapted to each other and fit together to form a limiting effect. In this embodiment of the utility model, the purpose of this setting is that, when the connector 3 is inserted into the control motherboard interface 4, the triangular locking block 61 squeezes the spring sheet 62 and deforms it, causing the triangular locking block 61 to enter the slot 63 to form a locking limit. After the anti-detachment seat 52 enters the limiting ring 55 and is squeezed, the anti-detachment seat 52 enters the limiting area 53. The chamfer on the limiting ring 55 and the anti-detachment seat 52 are adapted to fit each other to form a limiting effect. The specific installation method can be completed by pressing down and locking. The overall operation is simple and has an auxiliary protection effect on the stable connection and operation of the connector 3 and the control motherboard interface 4. When it is necessary to remove connector 3, pull the operating handle 64 directly to cause the spring plate 62 to deform, the slot 63 disengages from the triangular block 61, and then move connector 3 upward to move the triangular block 61 away from the spring plate 62. At the same time, the anti-disengagement seat 52 disengages from the limit ring 55, thereby completing the disengagement of connector 3 from the control motherboard interface 4. Example 2:

[0025] Please see Figures 1-4 This embodiment provides a technical solution based on embodiment one: the vehicle air sensor 1 includes a base 16, a connection terminal 11 connected to the data transmission line 2 is installed on the top of the base 16, a fastening seat 12 is fixedly installed on the top wall of the base 16 at the position corresponding to the connection terminal 11, a control module 15 is installed on the bottom of the base 16, a locking member 13 is installed on the bottom wall of the base 16 at the position corresponding to the control module 15, and a detection probe 14 connected to the control module 15 for detecting air quality is installed on the bottom wall of the base 16. In this embodiment of the utility model, the purpose of this arrangement is that the vehicle air sensor 1 is mainly composed of multiple components. It mainly detects air quality through the detection probe 14, and the control module 15 transmits the measured data through the data transmission line 2. The fastening seat 12 drives the base 16 and the locking member 13 to install the entire vehicle air sensor 1 into the reserved position and lock it in place.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] The working principle of this device is as follows: When using the vehicle air sensor 1, the movable base 16 drives the entire vehicle air sensor 1 to be installed in the reserved installation position on the vehicle. After the detection probe 14 is inserted into the installation position, the tool is used to operate the fastening seat 12 to drive the base 16 and the locking part 13 to be screwed and locked, thereby completing the installation and fixing of the vehicle air sensor 1. Then, the movable connector 3 drives the data transmission line 2 to be inserted into the control motherboard interface 4. When the connector 3 is inserted into the control motherboard interface 4, the movable positioning rod 51 drives the anti-detachment seat 52 to enter the limiting ring 55 on the upright 54. When the anti-detachment seat 52 contacts the limiting ring 55, the surrounding area is squeezed and contracted, thereby making the limiting area 53 fit and limit the inner wall of the limiting ring 55. Simultaneously, after the connector 3 drives the triangular locking block 61 past the position of the spring plate 62, the spring plate 62 undergoes elastic deformation, allowing the triangular locking block 61 to smoothly engage into the slot 63. After the connector 3 and the control motherboard interface 4 are connected and installed, the anti-detachment component 5 and the locking component 6 provide installation limit protection to prevent the connection from falling off. The detection probe 14 on the vehicle air sensor 1 transmits the monitored air quality data through the control module 15, data transmission line 2, connector 3, and control motherboard interface 4.
