Description

Technical Field

[0001] This utility model relates to the field of sensor installation technology, specifically a mounting and fixing structure for a vehicle air quality detection sensor. Background Technology

[0002] Vehicle air quality sensors are primarily used to detect the concentration of pollutants and environmental parameters in the air inside or outside the vehicle. Their core functions include monitoring harmful substances such as PM2.5, formaldehyde, and carbon dioxide, and transmitting data in real time to control the operation of the air purification system. The aforementioned technologies have certain shortcomings in their application: Currently, some air quality sensors are directly bolted to the outside of the air conditioner blower. However, directly using screws for fixing has some problems. If the bolts are tightened too much (excessive torque), it will cause a slight deformation of the sensor housing. This deformation will be directly transmitted to the internal sensing element, putting it in a stress environment that is not designed for it under static conditions. This will cause the measurement reference to drift and affect the deviation of the sensor's detection data.

[0003] To address this issue, the present invention provides a mounting and fixing structure for a vehicle air quality detection sensor. Summary of the Invention

[0011] Furthermore, ear grooves and through grooves are provided on the top wall of the support platform.

[0012] With the above technical solution, both the ear groove and the through groove are located at the top of the support platform.

[0013] Furthermore, the top wall of the support platform is provided with through slots, which are matched with the corresponding screw slots.

[0014] Through the above technical solution, the positions of the slot and the screw groove are matched, and a fastening connection is achieved by fastening bolts.

[0015] Furthermore, the same fastening bolt is screwed onto both the through slot and the corresponding screw groove inner wall.

[0016] With the above technical solution, the fastening bolts are inserted into the slots and threaded grooves for installation and connection. Beneficial effects

Detailed Implementation

[0021] 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:

[0022] Please see Figures 1-6 A vehicle air quality detection sensor mounting and fixing structure includes a mounting platform 1, a bracket assembly 5 mounted on the top of the mounting platform 1, a plurality of top-mounting components 4 evenly mounted inside the bracket assembly 5, a snap-fit ​​assembly 2 mounted on the top of the bracket assembly 5, a base 6 snap-fitted onto the outer wall of the snap-fit ​​assembly 2, and a sensor body 3 for detecting vehicle air quality mounted on the top of the base 6. The buckle assembly 2 includes positioning seats 21 fixedly installed at the four corners of the top of the bracket assembly 5. Several positioning seats 21 are all L-shaped. The inner wall of the positioning seats 21 is attached to the four corners of the outer wall of the base 6 to form a circumferential positioning installation of the base 6. Elastic seats 22 are fixedly installed at the front and rear of the top wall of the bracket assembly 5. Locking blocks 23 are fixedly installed at the positions between the elastic seats 22. The outer wall of the base 6 and the corresponding position of the locking blocks 23 are provided with locking grooves 25. Pull rings 24 are fixedly installed on the outer wall of the elastic seats 22. The top assembly 4 includes an ear groove 41 opened on the top of the support assembly 5. The top wall of the ear groove 41 is provided with a through groove 45. An ejection spring 44 is installed on the inner wall of the ear groove 41. The top of the ejection spring 44 is fixedly installed on the ear seat 43 that slides on the inner wall of the ear groove 41. The top wall of the ear seat 43 is fixedly installed on the ejection seat 42 that slides in the inner wall of the through groove 45. The top of the ejection seat 42 is abutted and fixed to the bottom wall of the base 6. In this embodiment of the utility model, the purpose of this setting is that the buckle assembly 2 is set up to complete the installation connection by snapping and fixing the buckle block 23 and the buckle groove 25. The sensor body 3 can be installed and limited by pressing the buckle, which changes the drawback of the traditional method of directly tightening with bolts. At the same time, after the sensor body 3 is installed, the upward pushing force of the upper push assembly 4 can push the base 6 and the sensor body 3 out from the bottom, thereby increasing the strength of the snapping structure of the buckle block 23 and the buckle groove 25 and improving the installation stability of the sensor body 3. Example 2:

[0023] Please see Figures 1-6 This embodiment provides a technical solution based on embodiment one: the bracket assembly 5 includes support columns 52 fixedly installed at the four corners of the top wall of the mounting platform 1. Each support column 52 has a screw groove at its top end and the same support platform 51 at its top end. The top wall of the support platform 51 is attached to the bottom wall of the base 6. The top wall of the support platform 51 is fixedly connected to the bottom wall of the positioning seat 21 and the elastic card seat 22. The top wall of the support platform 51 has an ear groove 41 and a through groove 45. The top wall of the support platform 51 has a through slot 54. The through slot 54 matches the position of the corresponding screw groove. The same fastening bolt 53 is screwed into the inner wall of the through slot 54 and the corresponding screw groove. In this embodiment of the utility model, the purpose of this arrangement is that the bracket assembly 5 establishes an installation position on the top of the mounting platform 1 through the support platform 51 and the support column 52, so that the sensor body 3 can be smoothly installed on the top wall of the support platform 51. With the cooperation of the buckle assembly 2, the sensor body 3 is installed and fixed.

[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] The working principle of this device is as follows: First, when installing the sensor body 3, the movable support platform 51 is placed on the top of the support column 52, so that the through slot 54 corresponds to the screw groove at the top of the support column 52. Then, the fastening bolt 53 passes through the through slot 54 and is screwed into the screw groove to achieve fastening and fixation, so that the support platform 51, the support column 52 and the mounting platform 1 are installed and connected. The active sensor body 3 drives the base 6 to be inserted from top to bottom. After the base 6 comes into contact with the locking block 23, it will generate a squeezing force, causing the elastic locking seat 22 to open outward and deform. As the base 6 and the sensor body 3 continue to go deeper, the locking block 23 engages and enters the slot 25. The outer wall of the base 6 fits against the inner wall of the positioning seat 21. After the base 6 is placed on top of the support platform 51, the bottom wall of the base 6 presses the ejector seat 42 into the through groove 45 and the ear groove 41. The ejector seat 42 drives the ear seat 43 to slide in the inner wall of the ear groove 41 and compress the ejector spring 44. Under the elastic action of the ejector spring 44, the ear seat 43 and the ejector seat 42 push back to form an elastic ejection force on the bottom of the base 6, which further improves the clamping and fastening force of the locking block 23 and the locking groove 25, and increases the installation stability and firmness of the sensor body 3.
