Description

Technical Field

[0001] This invention belongs to the field of automotive autonomous driving technology, and specifically relates to an automotive autonomous driving assistance device. Background Technology

[0002] Autonomous vehicles, also known as driverless cars, computer-driven cars, or wheeled mobile robots, are intelligent vehicles that achieve driverless operation through computer systems. Autonomous vehicles rely on the collaborative efforts of artificial intelligence, visual computing, radar, monitoring devices, and global positioning systems to enable computers to automatically and safely operate motor vehicles without any active human intervention.

[0003] Autonomous vehicles require cameras to monitor and observe the environment around the vehicle. Most cameras are external and do not have protective measures. If the camera lens is hit by a small object, it may break, which will affect the accuracy of the camera system's judgment and cause harm to the people in the vehicle when it is driving on the road. Summary of the Invention

[0004] The purpose of this invention is to provide an autonomous driving assistance device for automobiles. This invention aims to solve the technical problem that existing autonomous vehicles require cameras to monitor and observe the surrounding environment. Generally, these cameras are external, and if there are no protective measures on their surfaces, objects touching the camera may cause damage or lens breakage. This can affect the accuracy of the camera system's judgments and pose a danger to occupants while the vehicle is on the road.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An autonomous driving assistance device for automobiles includes:

[0007] Mounting plate;

[0008] The camera is fixed to the end of the mounting plate;

[0009] A protective ring is fitted onto the surface of the camera; and

[0010] The buffer mechanism comprises two sets, which are symmetrically arranged on the mounting plate and distributed on both sides of the camera to protect the camera.

[0011] Each set of buffer mechanisms includes a buffer plate, a first fixing rod, a fixing block, a sliding plate, a second fixing rod, and a first spring. The buffer plate is movably disposed at the end of the mounting plate. At least two first springs are provided, and at least two first springs are fixed between the protective ring and the camera. The sliding plate is fixedly connected to the end of the buffer plate, and the end of the sliding plate has a first hollow groove. The first fixing rod is fixed to the end of the mounting plate, and the fixing block is fixed to the surface of the first fixing rod. The end of the fixing block has a fifth hollow groove, and the second fixing rod is fixed between the inner walls on both sides of the fifth hollow groove. The second fixing rod is located inside the first hollow groove.

[0012] As a preferred embodiment of the present invention, the circumferential surface of the camera is provided with a transparent cover, and the opening of the transparent cover matches the protective ring.

[0013] As a preferred embodiment of the present invention, the inner wall of the camera has two sixth hollow grooves.

[0014] As a preferred embodiment of the present invention, a second spring is fixed to one side of the inner wall of each of the two sixth hollow grooves, and an oblique fixing block is fixed to one side of each of the two second springs. Two second hollow grooves are formed on the surface of the protective ring, and the two oblique fixing blocks are slidably connected to the two second hollow grooves respectively.

[0015] As a preferred embodiment of the present invention, a third hollow groove is provided on one side inner wall of each of the two sixth hollow grooves, and a tie rod is slidably connected in each of the two third hollow grooves. The two tie rods are respectively fixed to two inclined fixing blocks.

[0016] As a preferred embodiment of the present invention, a fourth hollow groove is provided at one end of the mounting plate.

[0017] In a preferred embodiment of the present invention, each of the two buffer plates is fixedly connected to a sliding block at its end, and both sliding blocks are slidably connected within the fourth hollow groove.

[0018] In a preferred embodiment of the present invention, a telescopic rod is fixed between the buffer plate and the sliding plate to support the buffer plate and the sliding plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In this solution, when an object hits the camera, the buffer mechanism can be set up to reduce the impact of the object, thereby reducing the force of the impact and protecting the camera lens or the overall safety, making it less likely to be damaged, and effectively improving the safety of the camera.

[0021] 2. In this solution, if the lens of an external camera is not protected, it may be damaged when it is impacted. By setting a transparent cover over the lens of the camera, the safety of the camera can be protected. Moreover, the transparent cover is not likely to affect the visual effect of the camera's shooting, thus effectively improving the safety of the camera lens.

[0022] 3. In this solution, when the transparent cover needs to be attached to the surface of the protective ring, first hold the transparent cover and push it towards the protective ring. When the inclined surface of the inclined fixing block contacts the protective ring, it can be squeezed into the sixth hollow groove. At this time, the elastic force of the second spring will be compressed. When the inclined fixing block slides to the upper side of the second hollow groove, the inclined fixing block will have no resistance. The elastic force of the second spring can then eject the inclined fixing block into the second hollow groove, so that the transparent cover is fixed to the circumferential surface of the protective ring and is stable, making it less likely for the transparent cover to fall off during use.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figures 1-6 The present invention provides the following technical solutions:

[0034] Mounting plate 1;

[0035] Camera 14 is fixed to the end of mounting plate 1;

[0036] Protective ring 4 is fitted onto the surface of camera 14; and

[0037] The buffer mechanism consists of two sets, symmetrically arranged on the mounting plate 1 and distributed on both sides of the camera 14, which are used to protect the camera 14.

[0038] Each set of buffer mechanisms includes a buffer plate 2, a first fixing rod 6, a fixing block 7, a sliding plate 8, a second fixing rod 18, and a first spring 5. The buffer plate 2 is movably disposed at the end of the mounting plate 1. At least two first springs 5 ​​are provided, and at least two first springs 5 ​​are fixed between the protective ring 4 and the camera 14. The sliding plate 8 is fixedly connected to the end of the buffer plate 2, and a first hollow groove 9 is opened at the end of the sliding plate 8. The first fixing rod 6 is fixed to the end of the mounting plate 1. The fixing block 7 is fixed to the surface of the first fixing rod 6. A fifth hollow groove 17 is opened at the end of the fixing block 7. The second fixing rod 18 is fixed between the inner walls on both sides of the fifth hollow groove 17. The second fixing rod 18 is located inside the first hollow groove 9.

[0039] In a specific embodiment of the present invention, when an object collides with the camera 14, the buffer plate 2 provides cushioning and protection upon impact. The object impacts the surface of the buffer plate 2, where the elastic force of the first spring 5 compresses it, reducing the impact speed. As the buffer plate 2 moves inward, the first hollow groove 9 at one end of the sliding plate 8 slides within the fifth hollow groove 17 at one end of the fixing block 7. The second fixing rod 18 prevents the sliding plate 8 from falling, ensuring its stability. The first fixing rod 6 stabilizes the fixing block 7. Upon impact, the sliding plate 8 moves in a straight line. At this time, the object hits the surface of the buffer plate 2, which reduces the impact force and the damage to the camera 14, thus protecting the safety of the camera 14. The protective ring 4 can protect the secondary stability of the camera 14. When the object is slowed down by the buffer mechanism, the protective ring 4 can further protect the safety of the camera 14, effectively improving the safety of the camera 14 in use. It should be noted that the specific model of camera 14 used shall be selected by those skilled in the art, and the above information about the camera 14 is existing technology and will not be elaborated in this solution.

[0040] Please refer to the details. Figure 1 The camera 14 has a transparent cover 10 on its circumferential surface, and the opening of the transparent cover 10 matches the protective ring 4.

[0041] In this embodiment: If the lens of the external camera 14 is not protected, the lens may be damaged when it is hit. By setting a transparent cover 10 to cover the lens of the camera 14, the safety of the camera 14 can be protected. Moreover, the transparent cover 10 is transparent and does not easily affect the shooting visual effect of the camera 14, thus effectively improving the safety of the lens of the camera 14.

[0042] Please refer to the details. Figure 3 The inner wall of the transparent cover 10 has two sixth hollow grooves 19. A second spring 21 is fixed to one side of the inner wall of each of the two sixth hollow grooves 19. An oblique fixing block 20 is fixed to one side of each of the two second springs 21. The surface of the protective ring 4 has two second hollow grooves 11. The two oblique fixing blocks 20 are slidably connected to the two second hollow grooves 11 respectively.

[0043] In this embodiment: when it is necessary to attach the transparent cover 10 to the surface of the protective ring 4, first hold the transparent cover 10 and push it towards the protective ring 4. When the inclined surface of the inclined fixing block 20 contacts the protective ring 4, the inclined fixing block 20 can be squeezed into the sixth hollow groove 19. At this time, the elastic force of the second spring 21 will be squeezed. When the inclined fixing block 20 slides to the upper side of the second hollow groove 11, the inclined fixing block 20 will have no resistance. The elastic force of the second spring 21 can then eject the inclined fixing block 20 into the second hollow groove 11, so that the transparent cover 10 is fixed to the circumferential surface of the protective ring 4 stably, and it is not easy for the transparent cover 10 to fall off during use.

[0044] Please refer to the details. Figure 3 Each of the two sixth hollow grooves 19 has a third hollow groove 12 on one side of its inner wall. Each of the two third hollow grooves 12 has a pull rod 13 slidably connected inside it. The two pull rods 13 are respectively fixed to the two inclined fixing blocks 20.

[0045] In this embodiment: when the transparent cover 10 needs to be disassembled for cleaning or replacement, the pull rod 13 in the third hollow groove 12 can be pulled first. At this time, the pull rod 13 can pull the inclined fixing block 20 in the second hollow groove 11. When the inclined fixing block 20 is pulled back into the sixth hollow groove 19, the transparent cover 10 can be pulled out, and personnel can then pull out the transparent cover 10 for cleaning and replacement.

[0046] Please refer to the details. Figure 2 The mounting plate 1 has a fourth hollow groove 16 at one end, and the two buffer plates 2 are fixedly connected to the ends of the sliding blocks 15, and the two sliding blocks 15 are slidably connected in the fourth hollow groove 16.

[0047] In this embodiment, by sliding the sliding block 15 within the fourth hollow groove 16, the buffer plate 2 can be cushioned when it approaches the camera 14 upon impact, making it less likely for the buffer plate 2 to bend, thus effectively improving the stability of the buffer plate 2.

[0048] Please refer to the details. Figure 2 A telescopic rod 3 is fixed between the buffer plate 2 and the sliding plate 8, which is used to support the buffer plate 2 and the sliding plate 8.

[0049] In this embodiment, the telescopic rod 3 allows the buffer plate 2 to be cushioned when it is squeezed inward, preventing excessive speed and potential damage. This also cushions the movement of the sliding plate 8, effectively allowing it to run slowly.

[0050] The working principle and usage of this invention are as follows: When an object collides with the camera 14, the buffer plate 2 provides cushioning and protection. The object impacts the surface of the buffer plate 2, where the spring force of the first spring 5 compresses it, reducing the impact speed. As the buffer plate 2 moves inward, the first hollow groove 9 at one end of the sliding plate 8 slides within the fifth hollow groove 17 at one end of the fixing block 7. The second fixing rod 18 prevents the sliding plate 8 from falling and ensures its stability. The first fixing rod 6 stabilizes the fixing block 7. During impact, the sliding plate 8 moves in a straight line, and the impact of the object on the surface of the buffer plate 2 reduces the impact force and minimizes the damage to the camera 14.

[0051] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
