Description

Technical Field

[0001] The present invention relates to the technical field of automatic driving of automobiles, and in particular to a vehicle-mounted photosensor structure based on automatic driving of automobiles. Background Art

[0002] As autonomous driving technology continues to advance, on-board light sensors, as key components for sensing ambient light intensity, play a vital role in the safe and stable operation of autonomous driving systems. However, existing on-board light sensors have numerous shortcomings in their mounting structures, severely impacting their performance and reliability.

[0003] Currently, many automotive light sensors are installed using simple methods, typically bolted or using simple plug-and-unplug connections. While bolted mounting ensures sensor stability to a certain extent, the installation process is cumbersome and requires specialized tools. Furthermore, during driving, the bolts can loosen due to factors such as vibration, causing the sensor to shift or fall off, affecting its accurate light perception. Simple plug-and-unplug connections struggle to ensure a tight fit between the sensor and the vehicle mounting area, and can easily lead to unstable connections due to vehicle vibration, affecting the sensor's proper operation.

[0004] Furthermore, existing on-board light sensors have poor positioning accuracy. Due to the lack of an effective positioning structure, the sensors may experience angular deviation or positional shift after installation. This can lead to inaccurate light data collected, affecting the autonomous driving system's understanding of the surrounding environment and increasing driving safety risks.

[0005] In summary, existing on-board photosensitive sensor mounting structures have numerous issues with ease of installation, stability, positioning accuracy, and versatility, failing to meet the growing demand for autonomous driving technology. Therefore, a new on-board photosensitive sensor structure is urgently needed to improve installation efficiency, enhance stability, improve positioning accuracy, and possess good versatility. Summary of the Invention

[0006] In order to overcome the existing problems, the embodiment of the present application provides a vehicle-mounted photosensitive sensor structure based on automatic driving of a car, a positioning hole is opened on the surface wall of the connecting column, and a positioning column is set at the corresponding position on the connecting seat. When the connecting column is inserted into the connecting seat, the positioning column can be accurately inserted into the positioning hole, further improving the accuracy and stability of the connection, and ensuring that the photosensitive sensor body will not have angular deviation or position offset after installation, thereby ensuring that the light data collected by the sensor is accurate and reliable.

[0007] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0008] A vehicle-mounted photosensor structure based on automatic driving of a vehicle comprises a photosensor body and a connecting seat arranged at one end of the photosensor body;

[0009] Among them, the photosensor body is provided with a connecting column at one end of the connecting seat, a limit block is provided at the bottom end of the connecting column, a positioning hole is opened on the surface wall of the connecting column, the connecting seat is provided with a positioning column at the position corresponding to the positioning hole, and the connecting seat is provided with a limit groove at the position corresponding to the limit block.

[0010] Preferably, the connecting column and the connecting seat are made of high-strength engineering plastics or metal alloys. The connecting column is fixed to one end of the photosensor body, and the connecting seat is installed at the corresponding installation position of the car. During installation, align the connecting column with the insertion hole of the connecting seat, and gently insert the connecting column into the connecting seat so that the limit block falls accurately into the limit groove to complete the initial positioning.

[0011] Preferably, the limit block is a long strip structure, the limit groove matches the shape of the limit block, the surface of the limit block is provided with anti-slip texture, the inner wall of the limit groove is provided with corresponding texture, the anti-slip texture is processed on the surface of the limit block by knurling, etching or injection molding, and the inner wall of the limit groove is also processed with matching texture by corresponding technology. The shape of the anti-slip texture can be straight, twill or grid texture, etc., which increases the friction between the limit block and the limit groove and prevents the limit block from sliding in the limit groove.

[0012] Preferably, a connecting wire is provided on a side of the connecting column away from the positioning hole, and a through hole is opened on the connecting seat at a corresponding position of the connecting wire. After the connecting column is connected to the connecting seat, the connecting wire inside the connecting column passes through the through hole.

[0013] Preferably, installation marks are set on the connecting column and the connecting seat, and the installation marks include arrows, color marks or text descriptions. During the installation process, the installer can quickly and accurately insert the connecting column into the correct position of the connecting seat by observing the installation marks, avoiding problems caused by installation errors, further simplifying the installation process, and improving installation accuracy.

[0014] Preferably, the surface of the positioning post is coated with anaerobic adhesive to enhance the reliability of the connection with the positioning hole. The anaerobic adhesive is evenly coated on the surface of the positioning post, and the coating thickness is controlled within an appropriate range. When the positioning post is inserted into the positioning hole, the anaerobic adhesive solidifies in an oxygen-free environment, firmly bonding the positioning post to the positioning hole, thereby enhancing the reliability of the connection between the positioning post and the positioning hole and preventing the positioning post from falling out of the positioning hole.

[0015] The advantages of the embodiments of the present application are:

[0016] A connecting column is set at one end of the photosensor body, and a connecting structure adapted to the connecting column is set at the corresponding position of the connecting seat. A limit block is provided at the bottom end of the connecting column, and a limit groove is provided on the connecting seat. The limit block matches the limit groove in shape, so that the connecting column can be accurately inserted into the connecting seat, and the displacement of the connecting column in the connecting seat is limited by the cooperation of the limit block and the limit groove, ensuring that the photosensor body is tightly installed and will not fall off due to vibration or shaking during vehicle driving. A positioning hole is provided on the surface wall of the connecting column, and a positioning column is provided at the corresponding position of the connecting seat. When the connecting column is inserted into the connecting seat, the positioning column can be accurately inserted into the positioning hole, further improving the accuracy and stability of the connection, and ensuring that the photosensor body will not have angular deviation or position offset after installation, thereby ensuring that the light data collected by the sensor is accurate and reliable.

[0025] The technical solution in the embodiments of the present application is to solve the above problems, and the overall idea is as follows:

[0026] Example

[0027] This embodiment provides a specific structure of a vehicle-mounted photosensitive sensor structure based on automatic driving of a car, such as Figure 1-4 As shown, it includes a photosensor body 2 and a connecting base 1 provided at one end of the photosensor body 2;

[0028] Among them, the photosensitive sensor body 2 is provided with a connecting column 3 at one end of the connecting seat 1, a limit block 5 is provided at the bottom end of the connecting column 3, a positioning hole 6 is opened on the surface wall of the connecting column 3, and a positioning column 9 is provided at the corresponding position of the positioning hole 6 of the connecting seat 1, and a limit groove 7 is provided at the corresponding position of the limit block 5 of the connecting seat 1.

[0029] Furthermore, the positioning hole 6 is processed on the surface wall of the connecting column 3 by a drilling process. During the process of inserting the connecting column 3 into the connecting seat 1, the positioning column 9 is automatically aligned with the positioning hole 6 and inserted to achieve precise positioning. The interference fit between the positioning column 9 and the positioning hole 6 is designed according to actual needs to ensure the stability and accuracy of the connection.

[0030] The connecting column 3 and the connecting base 1 are made of high-strength engineering plastics or metal alloy.

[0031] Furthermore, the connecting column 3 and the connecting seat 1 are made of high-strength engineering plastics or metal alloys. High-strength engineering plastics such as polycarbonate have good mechanical properties and weather resistance. The connecting column 3 is fixed to one end of the photosensor body 2, and the connecting seat 1 is installed in the corresponding installation position of the car. During installation, align the connecting column 3 with the insertion hole of the connecting seat 1, and gently insert the connecting column 3 into the connecting seat 1 so that the limit block 5 falls accurately into the limit groove 7 to complete the initial positioning.

[0032] The limiting block 5 is a long strip structure, the limiting groove 7 matches the shape of the limiting block 5, the surface of the limiting block 5 is provided with anti-slip lines, and the inner wall of the limiting groove 7 is provided with corresponding lines.

[0033] Furthermore, anti-slip patterns are processed on the surface of the limit block 5 using processes such as knurling, etching or injection molding, and matching patterns are also processed on the inner wall of the limit groove 7 using corresponding processes. The shape of the anti-slip patterns can be straight, twill or grid patterns, etc., which increases the friction between the limit block 5 and the limit groove 7 and prevents the limit block 5 from sliding in the limit groove 7.

[0034] A connecting line 4 is provided on a side of the connecting column 3 away from the positioning hole 6 , and a through hole 8 is formed in the connecting base 1 at a position corresponding to the connecting line 4 .

[0036] Furthermore, installation marks are set on the connecting column 3 and the connecting seat 1 by laser engraving, printing or pasting. For example, an arrow is engraved on the connecting column 3 to indicate the insertion direction, and an arrow of the same color is set at the corresponding position on the connecting seat 1; or text instructions are printed on the connecting column 3 and the connecting seat 1. During the installation process, the installer can quickly and accurately insert the connecting column 3 into the correct position of the connecting seat 1 by observing the installation mark, avoiding problems caused by installation errors, further simplifying the installation process, and improving the accuracy of installation.

[0037] The surface of the positioning column 9 is coated with anaerobic adhesive to enhance the reliability of the connection with the positioning hole 6 .

[0038] Furthermore, anaerobic adhesive is evenly coated on the surface of the positioning column 9, and the coating thickness is controlled within an appropriate range. When the positioning column 9 is inserted into the positioning hole 6, the anaerobic adhesive solidifies in an oxygen-free environment, firmly bonding the positioning column 9 and the positioning hole 6 together, thereby enhancing the reliability of the connection between the positioning column 9 and the positioning hole 6 and preventing the positioning column 9 from falling out of the positioning hole 6.
