[0026] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0027] Example 1:

[0028] Please see Figure 1-5 This utility model provides a technical solution:

[0029] A lidar mounting structure includes a mounting plate 1 for fixing the lidar, which is embedded in the center of the front of the vehicle roof. The detection end of the lidar faces the direction of vehicle travel, and the lidar is smoothly connected to the mounting plate 1. A first chamfered locking block 2 is fixedly provided at the end of the mounting plate 1 facing the rear of the vehicle. A positioning groove adapted to the first chamfered locking block 2 is provided at the front of the vehicle roof. A guide plate 4 is provided on the side of the mounting plate 1 that conforms to the vehicle body. The guide plate 4 is parallel to the installation direction of the mounting plate 1. A guide groove matching the guide plate 4 is provided at the front of the vehicle roof. Elastic locking members are provided on both sides of the mounting plate 1, and an unlocking device for controlling the retraction of the elastic locking members is provided in the middle of the mounting plate 1.

[0030] In the above scheme, the mounting plate 1 is embedded in the center of the front of the roof, and the lidar is fixedly installed in the center of the front of the roof along with the mounting plate 1, with the detection end facing the direction of vehicle travel. The rear end of the mounting plate 1 is provided with a first chamfered locking block 2, which cooperates with the positioning groove of the roof to achieve longitudinal positioning; the side that fits against the vehicle body is provided with a guide plate 4, which matches the guide groove of the roof to ensure that the mounting plate 1 slides in along the preset direction. Through the mechanical insertion and guiding structure in the above scheme, rapid alignment and precise positioning are achieved, avoiding manual installation deviation. Through the elastic locking members on both sides of the mounting plate 1, the mounting plate 1 is laterally locked to the front of the roof. Through longitudinal positioning and lateral locking, the mounting plate 1 is firmly fixed in the center of the front of the roof.

[0031] The elastic locking component includes a guide gear 7. A rotating groove 8 is provided on the side of the mounting plate 1, and the guide gear 7 is installed inside the rotating groove 8. A sliding groove 9 is provided inside the rotating groove 8, and a toothed plate 10 is provided on one side of the sliding groove 9. A toothed groove is provided on one side of the toothed plate 10, and the guide gear 7 engages with the toothed groove of the toothed plate 10. A return spring 12 is fixedly connected to the side of the toothed plate 10 away from the guide gear 7, and the return spring 12 pushes the toothed plate 10 closer to the guide gear 7. Guide racks 13 adapted to the guide gear 7 are provided on both sides of the front of the roof. The guide racks 13 are made of rust-resistant metal.

[0032] In the above scheme, the guide gear 7 is installed in the rotating groove 8 and meshes with the toothed plate 10 in the sliding groove 9. The toothed plate 10 is pushed by the return spring 12 and always maintains close contact with the guide gear 7. This structure is mainly used for locking the installation of the guide gear 7.

[0033] During installation, the guide gear 7 meshes with the guide racks 13 on both sides of the roof. The rotation of the gear drives the mounting plate 1 to slide smoothly in. The rust-proof metal material of the racks ensures durability. Through gear and rack transmission, the installation process is smoother. When the mounting plate 1 is in place, the return spring 12 pushes the tooth groove of the toothed plate 10 to engage with the guide gear 7. Since the guide gear 7 meshes with the guide racks 13 and the toothed plate 10 on both sides respectively, the rotation of the guide gear 7 is restricted, providing a self-locking force to prevent loosening and ensure the stable installation of the mounting plate 1.

[0034] The unlocking device includes a first electromagnet 15, with magnetic plates 16 on both sides of the first electromagnet 15. When the first electromagnet 15 is energized, the magnetic plates 16 adhere to the first electromagnet 15, and the electromagnet is powered through a connector. A connecting rod 17 is fixedly connected between the toothed plate 10 and the first electromagnet 15, and a return spring 12 is sleeved on the outside of the connecting rod 17.

[0035] In the above scheme, after the first electromagnet 15 and the magnetic suction plate 16 are energized, the electromagnet attracts the magnetic suction plates 16 on both sides, and pulls the gear plate 10 away from the guide gear 7 through the connecting rod 17, thus disengaging the engagement. The linkage between the return spring 12 and the connecting rod 17, through the spring sleeve on the connecting rod 17, pushes the gear plate 10 to reset when the power is off, and relocks it. The above scheme realizes one-button electric unlocking, simplifies the disassembly and assembly process, and avoids the use of mechanical tools.

[0036] The mounting plate 1 has a waterproof sealing strip on the contact surface with the roof, and the inner walls of the guide groove and positioning groove are embedded with shock-absorbing rubber layers; the power supply line of the unlocker is integrated inside the first chamfered card block 2, and contact power is achieved through the conductive contacts preset on the roof.

[0037] In the above solution, waterproof sealing strips prevent rainwater from seeping in through the gap between the mounting plate 1 and the roof. A shock-absorbing rubber layer is embedded in the guide groove and positioning groove to buffer the impact of vehicle vibrations on the lidar. The first chamfered locking block 2 has built-in conductive contacts that automatically energize upon insertion, avoiding exposed cables and simplifying the electrical wiring structure.

[0038] Example 2:

[0039] Please see Figure 1 , Figure 2 and Figure 5 Furthermore, in conjunction with Embodiment 1, it is found that, unlike Embodiment 1, the elastic locking component is an elastic locking tongue 18, and locking grooves that cooperate with the elastic locking tongue 18 are provided on both sides of the front part of the roof.

[0040] The end of the elastic locking tongue 18 near the locking groove is chamfered, and the end of the elastic locking tongue 18 near the unlocker is fixedly connected to the connecting rod 17. The end of the connecting rod 17 near the electromagnet is fixedly connected to the magnetic plate 16.

[0041] In the above solution, the elastic locking tongue 18 is chamfered for easy insertion into the locking slot, and its end is connected to the magnetic plate 16 via a connecting rod 17. When the electromagnet is energized, the locking tongue is pulled back to unlock; when the power is off, the spring pushes the locking tongue out to lock. By providing another simplified locking method, it adapts to the needs of different vehicle models. The chamfered design reduces installation resistance, making installation and disassembly very convenient and improving work efficiency.

[0042] The working principle of this lidar mounting structure:

[0043] During installation, first align the first chamfered locking block 2 at the rear end of the mounting plate 1 with the positioning groove on the roof, and simultaneously align the guide plate 4 on the side of the mounting plate 1 with the guide groove on the roof. Push the mounting plate 1 in along the guide groove. At this time, the guide gears 7 on both sides of the mounting plate 1 will engage with the guide rack 13 on the roof, causing the mounting plate 1 to slide smoothly into place. After the mounting plate 1 is fully pushed in, the return spring 12 will push the toothed plate 10 to engage with the guide gear 7, forming a locked state. At this time, the guide gear 7 engages with both the guide rack 13 and the toothed plate 10, so that the mounting plate 1 is firmly fixed in both the lateral and longitudinal directions.

[0044] When disassembly is required, energizing the first electromagnet 15 will cause it to attract the magnetic plates 16 on both sides. The magnetic plates 16, via the connecting rod 17, will move the toothed plate 10, disengaging it from the guide gear 7 and thus releasing the locking state. At this point, the mounting plate 1 can be pulled out along the guide groove. After power is cut off, the return spring 12 will automatically push the toothed plate 10 back to its original position, restoring the locking function.

[0045] In another embodiment, a resilient locking tongue 18 is used instead of the guide gear 7 mechanism. During installation, the chamfered end of the resilient locking tongue 18 first contacts the locking groove and automatically compresses under the action of thrust. After the mounting plate 1 is in place, the resilient locking tongue 18 pops out under the action of the spring and locks into the locking groove. During disassembly, the connecting rod 17 is driven by an electromagnet to pull the locking tongue back to unlock.

[0046] The entire installation structure is also equipped with waterproof sealing strips to prevent water ingress, and shock-absorbing rubber layers are installed in the guide grooves and positioning grooves to buffer vibrations. The power supply line is integrated into the first chamfered locking block 2, and automatic power-on is achieved through contacts. This design makes installation and disassembly very convenient, while ensuring the stability and reliability of the installation.

[0047] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
