Description

Technical Field

[0001] The utility model relates to the technical field of cameras, in particular to a camera for autonomous driving data acquisition. Background Technique

[0002] Autonomous driving means that a vehicle can autonomously control its driving process to varying degrees without the operation of a human driver. The main components of autonomous driving data acquisition include but are not limited to cameras, lidar (LiDAR), millimeter-wave radars, ultrasonic sensors, GPS, inertial measurement units (IMUs), etc.

[0003] Currently, the patent with the publication number CN217283051U discloses a protective perception camera for autonomous driving vehicles, including a mounting frame. Both the left and right sides of the top of the mounting frame are fixedly connected with sleeves. The inner sides of the sleeves are sleeved with a perception camera body. Both the top and bottom of the right end of the sleeve are fixedly connected with connecting plates. The technical problems to be solved by this camera are insufficient cleaning protection and high use and maintenance costs. To solve the above technical problems, this camera provides a protective perception camera for autonomous driving vehicles. A driving motor drives a semi-gear to rotate. The meshing of the semi-gear with a closed tooth rail drives a reciprocating frame to reciprocate in the middle of the inner wall of the mounting box. Through the meshing of an open tooth rail with a spur gear, the reciprocating frame drives the spur gear to reciprocate. The spur gear drives a cleaning brush plate to reciprocally clean the outside of the lens through a connecting shaft, ensuring the normal operation of the perception camera body.

[0004] However, in the actual use process of the above camera, there are still the following problems: When the vehicle is parked in an outdoor environment in winter, because there is a large amount of water vapor in the air, these water vapors will fall onto the camera when the vehicle stops, and the outdoor temperature is relatively low, so these water vapors are very likely to frost, which will affect the data acquisition when the vehicle drives next time. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a camera for autonomous driving data acquisition to solve the problem that when an autonomous driving vehicle stops moving in an environment with a relatively low temperature such as in winter, water vapor falls on the surface of the camera body and solidifies to cause frosting.

[0006] The utility model provides the following technical solution: A camera for autonomous driving data acquisition, including a camera body installed on a mounting plate. Both ends of the mounting plate are respectively installed on two support frames on the roof of the vehicle. The outer wall of the camera body is connected with a power mechanism. The output end of the power mechanism is connected with a U-shaped frame. The other end of the U-shaped frame is connected with a support assembly. One side of the U-shaped frame is fixedly connected with a bellows. The other end of the bellows is connected with the mounting plate. The camera body is located inside the U-shaped frame and the bellows.

[0007] Further, the power mechanism includes a waterproof motor and a connecting block. The outer wall of the waterproof motor is fixedly connected to the outer wall of the camera body. A connecting hole is provided on the output shaft of the waterproof motor, and the connecting hole and the connecting block are tightly connected by bolts. The outer wall of the connecting block is fixedly connected to one end of the U-shaped frame.

[0008] Further, the support assembly includes a support block, a rotating rod, and a collar. The lower end of the support block is fixedly connected to the upper surface of the mounting plate. The upper end of the support block is sleeved and rotatably connected to one end of the rotating rod. The outer wall of the other end of the rotating rod is slidably connected to the inner wall of the collar. The outer wall of the collar is fixedly connected to the end of the U-shaped frame away from the connecting block.

[0009] Further, a receiving opening is provided through the upper surface of the mounting plate, and one end of the bellows away from the U-shaped frame is located within the receiving opening.

[0010] Further, a support plate is fixedly connected to the inner wall of the receiving opening, and the side wall of the support plate is fixedly connected to one end of the bellows away from the U-shaped frame.

[0011] Further, a plurality of ventilation holes are provided through one end of the bellows close to the support plate.

[0012] Further, a baffle is fixedly connected to the outer wall of the camera body. The side wall of the baffle abuts against the inner walls of the bellows and the U-shaped frame. One end of the baffle close to the mounting plate is also fixedly connected to the mounting plate, and the baffle is located directly above the receiving opening.

[0013] Further, a sealing groove is provided on the upper surface of the baffle, and a sealing strip is fixedly connected to the inner side wall of the U-shaped frame. The outer wall of the sealing strip is slidably connected to the inner wall of the sealing groove.

[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] For the camera used for autonomous driving data acquisition, by arranging a power mechanism outside the camera body, and connecting the U-shaped frame and the bellows through the power mechanism. When the autonomous driving vehicle does not need to collect data through the camera body, the U-shaped frame and the bellows can be controlled by the power mechanism and the support assembly to shield the camera body, thereby avoiding the problem that the camera body frosts due to the condensation of water vapor during the stop of the vehicle in a relatively low temperature environment such as winter.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0025] Please refer to Figures 1-7 , a camera for autonomous driving data collection, including a camera body 2 mounted on a mounting plate 1, both ends of the mounting plate 1 are respectively mounted on two support frames on the vehicle roof, the outer wall of the camera body 2 is connected with a power mechanism, the output end of the power mechanism is connected with a U-shaped frame 5, the other end of the U-shaped frame 5 is connected with a support assembly, one side of the U-shaped frame 5 is fixedly connected with a bellows cover 8, the other end of the bellows cover 8 is connected with the mounting plate 1, and the camera body 2 is located inside the U-shaped frame 5 and the bellows cover 8.

[0026] A camera for autonomous driving data collection in the present utility model is similar in structure to the existing cameras for autonomous driving data collection, such as a protective perception camera for autonomous driving vehicles disclosed in the patent with the publication number CN217283051U. As Figures 1 to 7As shown, when the camera for autonomous driving data collection in the present utility model is in normal use, the power mechanism can be started through the vehicle internal controller or the remote controller (this is prior art and thus will not be described in detail), and the U-shaped frame 5 and the bellows 8 are retracted behind the camera body 2, so as not to block the line of sight of the camera body 2. Subsequently, during the driving process of the vehicle, the camera body 2 can collect data normally.

[0027] When the autonomous driving vehicle does not need to collect data through the camera body 2, at this time, the power mechanism can be started again through the vehicle internal controller or the remote controller. After the power mechanism is started, cooperating with the support assembly at the other end of the U-shaped frame 5, the U-shaped frame 5 and the bellows 8 are controlled to rotate forward from behind the camera body 2, and thus the camera body 2 can be blocked, thereby avoiding the problem that the camera body 2 frosts due to the condensation of water vapor during the stop of the vehicle in a relatively low temperature environment such as in winter.

[0028] It should be particularly noted here that: the shutdown program of the power mechanism can be set in advance in the vehicle internal controller or the remote controller. For example, after the vehicle shuts off, the power mechanism automatically closes the U-shaped frame 5 and the bellows 8, thereby avoiding the situation that the camera body 2 is damaged due to forgetting to close the U-shaped frame 5 and the bellows 8.

[0029] Please mainly refer to Figures 5-7 , the power mechanism includes a waterproof motor 3 and a connecting block 12. The outer wall of the waterproof motor 3 is fixedly connected to the outer wall of the camera body 2. A connecting hole 301 is provided on the output shaft of the waterproof motor 3, and the connecting hole 301 and the connecting block 12 are tightly connected by bolts. The outer wall of the connecting block 12 is fixedly connected to one end of the U-shaped frame 5.

[0030] More specifically, when it is necessary to control the opening and closing of the U-shaped frame 5 and the bellows 8, only the waterproof motor 3 needs to be turned on. As the output shaft of the waterproof motor 3 rotates, the connecting block 12 can be driven to rotate.

[0031] And because the connecting block 12 and the output shaft of the waterproof motor 3 are connected by bolts, when the U-shaped frame 5 and the bellows 8 are damaged, the U-shaped frame 5 and the bellows 8 can also be disassembled, repaired and replaced.

[0032] It should be particularly noted here that: the motor having a waterproof function is a very mature prior art, and thus will not be described in detail here. And the motor needs to be waterproof here, considering that when the vehicle is walking or stopped outdoors, it is very easy to encounter weather such as rain and snow. Therefore, the waterproof motor 3 is set here, which can reduce the damage probability. Of course, an ordinary drive motor can also be used here, and a waterproof cover can be sleeved outside for protection, etc., which is not specifically limited.

[0033] Please mainly refer toFigure 5 and Figure 7 The support assembly includes a support block 4, a rotating rod 10 and a collar 11. The lower end of the support block 4 is fixedly connected to the upper surface of the mounting plate 1. The upper end of the support block 4 is sleeved and rotatably connected to one end of the rotating rod 10. The outer wall of the other end of the rotating rod 10 is slidably connected to the inner wall of the collar 11. The outer wall of the collar 11 is fixedly connected to the end of the U-shaped frame 5 away from the connecting block 12.

[0034] More specifically, under normal circumstances, the end of the U-shaped frame 5 away from the waterproof motor 3 can remain stationary under the support of the support block 4, the rotating rod 10 and the collar 11, thereby avoiding shaking.

[0035] Conversely, when the waterproof motor 3 drives the U-shaped frame 5 to rotate, the collar 11 at this end of the U-shaped frame 5 can also rotate inside the support block 4 through the rotating rod 10, thus not affecting the normal rotation.

[0036] It should be specifically noted here that the collar 11 is only inserted outside the rotating rod 10. In this way, after separating the waterproof motor 3 from the connecting block 12, this end of the U-shaped frame 5 can be quickly separated from the rotating rod 10. Of course, it can also be fixed by bolts or other means as long as it does not affect the rotation, and no specific limitation is made.

[0037] Please mainly refer to Figure 4 , a storage opening 101 is formed through the upper surface of the mounting plate 1, and one end of the bellows cover 8 away from the U-shaped frame 5 is located in the storage opening 101.

[0038] More specifically, although the bellows cover 8 is foldable, even after folding, there is still a certain thickness. At this time, by setting the storage opening 101, the bellows cover 8 can be stored therein, thereby reducing the space occupied above the mounting plate 1 and being relatively aesthetically pleasing.

[0039] Please mainly refer to Figure 3 , Figure 5 and Figure 6 , a support plate 9 is fixedly connected to the inner wall of the storage opening 101, and the side wall of the support plate 9 is fixedly connected to one end of the bellows cover 8 away from the U-shaped frame 5.

[0040] More specifically, by setting the support plate 9, a support and pulling force can be provided to one end of the bellows cover 8 away from the U-shaped frame 5, so that the bellows cover 8 does not move together with the U-shaped frame 5.

[0041] Please mainly refer to Figure 6 , a plurality of ventilation holes 801 are formed through one end of the bellows cover 8 close to the support plate 9.

[0042] More specifically, after the camera body 2 and the waterproof motor 3 work for a period of time, they will emit a certain degree of heat. If the vehicle stops at this time, and after the U-shaped frame 5 and the bellows cover 8 are closed, it is very likely that this heat cannot be discharged to the outside, thereby increasing the probability of damage. At this time, by providing the ventilation holes 801, the remaining heat can be slowly discharged.

[0043] Please refer mainly to Figure 1 、 Figure 3 and Figure 7 . A baffle 7 is fixedly connected to the outer wall of the camera body 2. The side wall of the baffle 7 abuts against the inner walls of the bellows cover 8 and the U-shaped frame 5. One end of the baffle 7 close to the mounting plate 1 is also fixedly connected to the mounting plate 1, and the baffle 7 is located directly above the receiving port 101.

[0044] More specifically, by providing the baffle 7 above the receiving port 101, a support can be provided for the bellows cover 8 and the U-shaped frame 5, making it more stable after folding.

[0045] Please refer mainly to Figures 3-7 . A sealing groove 701 is formed on the upper surface of the baffle 7. A sealing strip 6 is fixedly connected to the inner side wall of the U-shaped frame 5. The outer wall of the sealing strip 6 is slidably connected to the inner wall of the sealing groove 701.

[0046] More specifically, by providing the sealing groove 701 and the sealing strip 6, the receiving port 101 can be protected during the running of the vehicle (when the bellows cover 8 and the U-shaped frame 5 are in the unfolded state), so as to avoid external sundries from falling into the empty groove in the center of the bellows cover 8 and the U-shaped frame 5 (because the upper surface of the baffle 7 is flat, so even if sundries fall on it during running, they will be blown away during the running process).

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
