Description

Technical Field

[0001] This utility model belongs to the field of vehicle technology, specifically relating to a mounting bracket for vehicle-mounted visual inspection mechanisms. Background Technology

[0002] With the development of autonomous driving technology, vehicles need to integrate multiple sensors such as LiDAR and fisheye cameras to achieve environmental perception. The vehicle-mounted vision inspection mechanism mounting bracket refers to the mechanical load-bearing structure designed specifically for vehicle environmental perception systems. Through integrated layout and vibration reduction technology, LiDAR, cameras and other sensors are fixed to designated positions on the vehicle body.

[0003] Most existing vehicle-mounted vision inspection mechanism brackets use rubber vibration isolators. However, rubber vibration isolators can only attenuate high-frequency vibrations and are insufficient in suppressing low-frequency vibrations during vehicle start-stop / bumpy road conditions. They are also unable to cope with mixed high-frequency / low-frequency vibrations under complex road conditions. Furthermore, replacing the vision inspection mechanism requires complete disassembly, resulting in high maintenance costs. The exposed cables are easily damaged, and the lack of heat dissipation and protection design makes it difficult to stably apply to vehicle-mounted vision inspection mechanisms. Utility Model Content

[0004] To address the above issues and overcome the shortcomings of existing technologies, this utility model provides a mounting bracket for an in-vehicle vision inspection mechanism. This mounting bracket effectively suppresses high- and low-frequency mixed vibrations under complex road conditions, ensuring the overall stability of the vision inspection mechanism, reducing inspection errors, and providing good sealing and protection for its internal structure through its wiring and sealing structures, preventing dust or rainwater from affecting the internal structure. The mounting base allows for the quick and easy installation and removal of the vision inspection mechanism without the need to replace the entire unit, reducing maintenance costs and facilitating its use when installing an in-vehicle vision inspection mechanism.

[0005] A mounting bracket for an in-vehicle vision inspection mechanism includes a fixed base. A rubber vibration isolator for preliminary vibration reduction is fixedly mounted on the upper surface of the fixed base, and a connecting plate is fixedly connected to the top of the rubber vibration isolator. A vibration damping mechanism for precise vibration reduction is provided on the upper surface of the connecting plate, and a top mounting plate is provided at the top of the vibration damping mechanism. A sealing structure is provided between the connecting plate and the top mounting plate to ensure internal sealing. A mounting seat for mounting vision inspection equipment is fixedly mounted on the upper surface of the top mounting plate, and a cable threading structure for passing cables is fixedly connected to the center of the lower surface of the mounting seat. The cable threading structure passes vertically through the center of the top mounting plate, the connecting plate, and the fixed base.

[0006] Preferably, the center of the fixed base, connecting plate and top mounting plate are provided with a circular hole for threading the wire structure, and the inner sidewall of the circular hole is bonded with a rubber ring for vibration isolation.

[0007] Preferably, the wiring structure includes a wiring tube and heat dissipation fins. The number of heat dissipation fins is several, and the several heat dissipation fins are vertically fixed to the outside of the wiring tube in a ring array. The wiring tube and the heat dissipation fins are both inserted into multiple circular holes, and the heat dissipation fins can abut against the rubber rings inside the circular holes.

[0008] Preferably, the number of rubber vibration isolators is four, and the four rubber vibration isolators are fixedly installed on the upper surface of the fixed base in a rectangular array, and the connecting plate is fixedly installed on the top of the four rubber vibration isolators by bolts.

[0009] Preferably, the damping mechanism includes electromagnetic active dampers and spring buffer rods. The number of electromagnetic active dampers is three, and the three electromagnetic active dampers are fixedly installed on the upper surface of the connecting plate in an equilateral triangular configuration. The top mounting plate is fixedly connected to the top of the three electromagnetic active dampers. The number of spring buffer rods is several, and the several spring buffer rods are arranged in a rectangular array between the connecting plate and the top mounting plate and are located inside the sealing structure.

[0011] The beneficial effects of the above technical solution are as follows:

[0012] This mounting bracket for vehicle-mounted vision inspection mechanisms utilizes rubber vibration isolators, a damping mechanism, a sealing structure, a mounting base, and a wiring structure to form a double-layer damping base. The rubber vibration isolators effectively dampen high-frequency vibrations, while the damping mechanism dynamically adjusts according to the frequency and amplitude of the vibrations it receives, further suppressing low-frequency vibrations. Together, they form a composite damping system, which is more effective at suppressing mixed high- and low-frequency vibrations under complex road conditions, ensuring the overall stability of the vision inspection mechanism and reducing inspection errors. The wiring structure provides good heat dissipation and protection for the cables, effectively preventing cable damage. Simultaneously, the sealing structure provides excellent sealing protection for the internal structure, preventing dust or rainwater from affecting it. The mounting base allows for quick and easy installation and removal of the vision inspection mechanism without the need for complete replacement, reducing maintenance costs and making it more convenient for use when installing vehicle-mounted vision inspection mechanisms.

[0017] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 3 The embodiments are described in detail below.

[0018] This embodiment provides a mounting bracket for an in-vehicle vision inspection mechanism, as shown in the attached figure. Figure 1-3 As shown, the system includes a fixed base 1, which can be fixedly installed on the top of the vehicle. Rubber vibration isolators 2 for initial shock absorption are fixedly installed on the upper surface of the fixed base 1, and a connecting plate 3 is fixedly connected to the top of the rubber vibration isolators 2. The rubber vibration isolators 2 are existing known technology and will not be elaborated upon here. There are four rubber vibration isolators 2, which are fixedly installed on the upper surface of the fixed base 1 in a rectangular array. The connecting plate 3 is fixedly installed on the top of the four rubber vibration isolators 2 by bolts. The four rectangularly arranged rubber vibration isolators 2 provide stable support for the connecting plate 3 while effectively reducing the high-frequency vibration transmitted from the fixed base 1 to the connecting plate 3, thus providing initial shock absorption for the vehicle-mounted visual inspection mechanism installed on the top. The vehicle-mounted visual inspection mechanism is an intelligent perception system integrated into the vehicle using LiDAR, a fisheye camera, and AI algorithms; it is existing known technology and will not be elaborated upon here.

[0019] The upper surface of the connecting plate 3 is provided with a damping mechanism for precise vibration reduction, and a top mounting plate 4 is provided at the top of the damping mechanism. The damping mechanism includes electromagnetic active dampers 10 and spring buffer rods 11. There are three electromagnetic active dampers 10, and the three electromagnetic active dampers 10 are fixedly installed on the upper surface of the connecting plate 3 in an equilateral triangular configuration. The electromagnetic active dampers 10 are electrically connected to an external control unit and electrically connected to an external circuit through wires. The three electromagnetic active dampers 10 can provide active vibration reduction for the top mounting plate 4. The equilateral triangular configuration ensures the overall stability of the top mounting plate 4. At the same time, in conjunction with the spring buffer rods 11, the top mounting plate 4 can maintain good stability. The top mounting plate 4 is fixedly connected to the top of the three electromagnetic active dampers 10, and the spring buffer rods 11... The number of spring buffer rods 11 is several, and these spring buffer rods 11 are arranged in a rectangular array between the connecting plate 3 and the top mounting plate 4 and are located inside the sealing structure. Each spring buffer rod 11 includes a sleeve rod 15, a shock-absorbing spring 16, and a buffer rod 17. The buffer rod 17 is vertically inserted inside the sleeve rod 15 and its top end is fixedly connected to the lower surface of the top mounting plate 4. The shock-absorbing spring 16 is fixedly connected to the bottom end of the buffer rod 17 and is built into the sleeve rod 15. The bottom end of the shock-absorbing spring 16 is fixedly connected to the inner bottom wall of the sleeve rod 15. The sleeve rod 15 is fixedly connected to the upper surface of the connecting plate 3. The shock-absorbing spring 16 can reduce the vibration transmitted from the connecting plate 3 to the top mounting plate 4, and the multiple spring buffer rods 11 can ensure stable support for the top mounting plate 4, thus ensuring the stability of the vision inspection mechanism.

[0020] A sealing structure is provided between the connecting plate 3 and the top mounting plate 4 to ensure the internal sealing. The sealing structure includes an outer rectangular frame 12, a sealing gasket 13, and an inner rectangular frame 14. The sealing gasket 13 is adhered to the inner sidewall of the outer rectangular frame 12, and the outer rectangular frame 12 is fixedly connected to the upper surface of the connecting plate 3. The inner rectangular frame 14 is fixedly connected to the lower surface of the top mounting plate 4 and can be inserted into the sealing gasket 13 inside the outer rectangular frame 12 and fits against the inner sidewall of the sealing gasket 13. The inner rectangular frame 14 can move within the sealing gasket 13, which can ensure that the top mounting plate 4 and the connecting plate 3 can move relative to each other without affecting the shock absorption mechanism. At the same time, the sealing gasket 13 can provide a sealing and protective function between the connecting plate 3 and the top mounting plate 4, which can effectively prevent external impurities from entering its interior and ensure the normal operation of the internal structure.

[0021] A mounting base 5 for mounting vision inspection equipment is fixedly installed on the upper surface of the top mounting plate 4. The vehicle-mounted vision inspection mechanism can be fixedly installed on the mounting base 5, which facilitates quick installation and removal of the vision inspection mechanism. When the vision inspection mechanism needs to be replaced, only the vision inspection mechanism on the top of the mounting base 5 needs to be removed, without replacing the entire mounting bracket, thus saving costs. A cable-passing structure for cable routing is fixedly connected at the center of the lower surface of the mounting base 5. The cable-passing structure is vertically inserted at the center of the top mounting plate 4, the connecting plate 3, and the fixed base 1. The wiring structure includes a wiring tube 8 and heat dissipation fins 9. There are several heat dissipation fins 9, which are vertically fixed to the outside of the wiring tube 8 in a ring array. Both the wiring tube 8 and the heat dissipation fins 9 are inserted into multiple round holes 6. The heat dissipation fins 9 can abut against the rubber rings 7 inside the round holes 6. The heat dissipation fins 9 can provide good heat dissipation for the wiring tube 8, preventing the cable section from overheating and affecting the operation of the vision inspection mechanism. At the same time, the wiring tube 8 can provide good protection for the cable as a whole, preventing the cable from being exposed and damaged.

[0022] The center of the fixed base 1, the connecting plate 3 and the top mounting plate 4 are all provided with a circular hole 6 for passing through the wire structure, and the inner side wall of the circular hole 6 is bonded with a rubber ring 7 for vibration isolation. The rubber ring 7 can abut against the heat dissipation fins 9 around the wire tube 8, which can ensure a soft connection between the heat dissipation fins 9 and the circular hole 6, thereby preventing the impact on the overall vibration reduction performance of the mounting bracket.

[0023] In summary, the installation steps for this mounting bracket used in vehicle-mounted vision inspection mechanisms are as follows:

[0024] 1. The mounting bracket is fixedly installed on the vehicle body, and the vision inspection mechanism is installed on the mounting base 5. When the vehicle is in motion, the rubber vibration isolator 2 can play a preliminary shock absorption role on the vision inspection mechanism on the top, and can suppress the impact of high-frequency vibration generated when the vehicle is in motion on the vision inspection mechanism.

[0025] 2. The electromagnetic active shock absorber 10 and the spring buffer rod 11 can suppress low-frequency vibrations during vehicle start-stop / bumpy road conditions, thus working in conjunction with the rubber vibration isolator 2 to effectively cope with high-frequency / low-frequency mixed vibrations under complex road conditions.

[0026] 3. The sealing gasket 13 can seal and protect the connection plate 3 and the top mounting plate 4, effectively preventing external impurities from entering the interior and ensuring the normal operation of the internal structure. The heat dissipation fins 9 provide good heat dissipation for the conduit 8, preventing the cable section from overheating and affecting the operation of the vision inspection mechanism. At the same time, the conduit 8 provides good protection for the cable as a whole, preventing the cable from being exposed and damaged.
