Description

Technical Field

[0001] The utility model relates to the field of intelligent driving, and in particular to an automobile laser radar bracket. Background Art

[0002] In the intelligent driving system, the mature solutions that act as the eyes of the car mainly include laser radar and camera. Among them, the current automotive laser radar is generally installed on the top of the front windshield through a laser radar bracket;

[0003] For example, a Chinese patent with publication number CN110979194A discloses a combined intelligent driving car laser radar mounting bracket, including a bracket lower cover and a bracket upper cover, wherein the middle part of the top of the bracket lower cover is fixedly connected to the bottom of the bracket upper cover by bolts, and a top laser radar is arranged on the top of the bracket upper cover; this patent can install the laser radar, but it cannot compensate for the visual blind spot of the laser radar, because when the car is driving, if it encounters a steep slope or downhill, if the emission angle of the laser radar does not change, its intelligent observation in front of the vehicle will have a blind spot similar to that of a human perspective, such as going uphill, and only when you reach the top of the slope can you see the situation downhill.

[0026] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0027] Embodiment 1

[0028] See also Figure 1 As shown, a car laser radar bracket includes a bracket body 1, a fixing plate 2, a connecting plate 3 and a servo motor 4. The fixing plate 2 is fixed on the bracket body 1, and the connecting plate 3 is rotatably connected with the fixing plate 2. The connecting plate 3 is used to install the laser radar. The servo motor 4 is fixed on the fixing plate 2, and the output end of the servo motor 4 is linked with the connecting plate 3. The servo motor 4 is used to drive the connecting plate 3 to adjust the angle with the fixing plate 2, so as to compensate for the laser radar visual blind area. For example, see Figure 5 As shown, Figure 5 The S1 perspective is the unadjusted perspective, and the S2 perspective is the adjusted perspective. If the perspective of the laser radar itself does not change, raising the height of the connecting plate 3, that is, increasing the angle between the connecting plate 3 and the fixed plate 2, can increase the perspective of the laser radar. At this time, the car can observe farther roads, provide more prediction data for the intelligent driving system, and improve the safety of the intelligent driving system.

[0029] For details, see Figure 3 and Figure 4 As shown, a connecting pile 21 is fixed to the outer surface of the fixed plate 2, and the connecting plate 3 is rotatably connected to the connecting pile 21 through a shaft. A worm 41 is fixed to the output end of the servo motor 4, and the end of the worm 41 is rotatably connected to the fixed plate 2. A worm gear 31 is evenly fixed on the lower surface of the connecting plate 3 close to the worm 41 in an annular shape, and the worm gear 31 is meshed with the worm 41. The worm 41 is driven to rotate by the servo motor 4, and the worm 41 can push the worm gear 31, thereby changing the angle of the connecting plate 3.

[0030] For more details, see Figure 1As shown, the outer surface of the connecting plate 3 is evenly fixed with fixing piles 32 for connecting screws, so that the laser radar can be conveniently installed on the connecting plate 3 through the screws and the fixing piles 32.

[0031] For further information, see Figure 2 As shown, reinforcing ribs 11 are evenly fixed on one side of the bracket body 1 facing away from the fixing plate 2 to improve the strength of the bracket body 1, especially the strength of the laser radar installation point.

[0032] Embodiment 2

[0033] See also Figure 1 and Figure 3 As shown, based on the above embodiment, one end of the connecting plate 3 away from the servo motor 4 is hinged with a support member, and the support member includes: a telescopic tube 5, an end of which is rotatably connected to the lower surface of the connecting plate 3; a telescopic shaft 51, one end of which is telescopically connected to the telescopic tube 5, and the other end of which is rotatably connected to the outer surface of the fixed plate 2; a spring, which is sleeved on the telescopic shaft 51, and the two ends of the spring are respectively against the telescopic tube 5 and the fixed plate 2; the spring can provide elastic force for the telescopic tube 5, and when the servo motor 4 is not working, the telescopic tube 5, the telescopic shaft 51 and the spring cooperate to support the connecting plate 3, thereby ensuring the stability between the connecting plate 3 and the fixed plate 2.

[0034] The exemplary implementation scheme of the present disclosure is described in detail above with reference to the preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
