[0001] The present application relates to the field of vehicles, and in particular to a laser radar integrated device and a vehicle. Background Art

[0002] The vehicle-mounted lidar emits a laser beam to the target, then receives the signal wave reflected from the target, and after comparing the signal wave with the emitted laser beam and processing it, it can obtain parameters such as the target's distance, direction, altitude, speed, posture and shape.

[0003] Currently, automotive LiDAR is integrated into vehicles by fixing it to the outside of the vehicle body, meaning the LiDAR protrudes from the vehicle. This integration method affects the vehicle's lines, increases wind resistance, and leaves the LiDAR exposed, making it susceptible to damage. Summary of the Invention

[0033] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0035] like Figures 1 to 5As shown, an embodiment of the present application provides a laser radar integrated device, including a radar body 1, a housing 4, and a drive assembly 3. The housing 4 has a cavity for accommodating the radar body 1 and an opening communicating with the cavity. The drive assembly 3 includes a driver 31 and a rotating arm 2. The driver 31 may be a servo actuator. The base of the driver 31 is connected to the housing 4. The output shaft of the driver 31 is drivingly connected to the rotating arm 2. The end of the rotating arm 2 away from the driver 31 is connected to the radar body 1. The driver 31 can drive the rotating arm 2 to rotate, so that the radar body 1 is at least partially extended from the opening and retracted into the housing 4.

[0036] In a specific implementation, the housing 4 is located inside the vehicle body, and an opening is provided on the vehicle body. The opening of the housing 4 overlaps with at least a portion of the opening on the vehicle body. During automatic driving of the vehicle, the control system controls the driver 31 to drive the rotating arm 2, such as Figure 1 As shown, Figure 1 The radar body 1 is completely inserted into the cavity of the shell 4. When the radar body 1 is not working, the radar body 1 is located inside the shell 4. Figure 2 As shown, Figure 2 This is the posture in which the radar body 1 extends out of the shell 4 and emits a laser beam for detection. When the radar body 1 is working, the driver 31 drives the radar body 1 to extend out of the shell 4 and emit a laser beam for detection.

[0037] In the related art, the radar body 1 is directly fixed outside the vehicle body, which not only affects the aesthetic lines of the entire vehicle, but also increases the wind resistance of the vehicle when the vehicle is driving, causing the vehicle to generate unnecessary energy consumption. At the same time, the exposed laser radar is also easily damaged by foreign objects such as branches.

[0038] The laser radar integrated device provided in the embodiments of the present application comprises a housing 4 having a cavity for accommodating a radar body 1 and a drive assembly 3 connected to the radar body 1, enabling the drive assembly 3 to drive the radar body 1 to at least partially extend out of the housing 4. The drive assembly 3 comprises a driver 31 connected to the housing 4, a rotating arm 2 drivably connected to the driver 31, and the connection of the rotating arm 2 to the radar body 1, enabling the driver 31 to rotate the rotating arm 2. The rotation of the rotating arm 2 drives the radar body 1 to at least partially extend out of the housing 4. The radar body 1 can extend out of the housing 4 only when it is required to emit a laser beam; otherwise, it remains within the housing 4. This design does not affect the overall vehicle's lines, does not increase wind resistance during driving, and is also less susceptible to damage to the laser radar.

[0039] like Figure 1 and Figure 3As shown, in some embodiments, the front end of the radar body 1 is used to emit a laser beam. The housing 4 includes an open top wall 42. The portion of the top wall 42 opposite the front end of the radar body 1 extends into the cavity to form a connecting plate 5. The drive assembly 3 is mounted on the connecting plate 5. When the radar body 1 is located within the cavity of the housing 4, the top wall 42 abuts against the edge of the radar body 1 to form a seal. Furthermore, the connecting plate 5 extending from the top wall 42 provides support for the drive assembly 3.

[0040] Furthermore, the middle portion of the rotating arm 2 is bent away from the top wall 42 to avoid interference between the rotating arm 2 and the top wall 42 during rotation.

[0041] like Figure 1 and Figure 5 As shown, in some embodiments, the drive assembly 3 further includes a gear 32 drivingly connected to the driver 31. Arc teeth 21 are formed on the end of the rotating arm 2 proximate the driver 31. The arc teeth 21 mesh with the gear 32 for transmission. The radius of the arc teeth 21 is greater than the radius of the gear 32. The output shaft of the driver 31 is connected to the gear 32, thereby driving the gear 32 to rotate. The gear 32 transmits the output torque of the driver 31 to the rotating arm 2 via the arc teeth 21, causing it to rotate. The radius of the arc teeth 21 is greater than the radius of the gear 32, which helps reduce the output load on the driver 31 and improve the life of the driver 31.

[0042] In some embodiments, as Figures 3 to 5 As shown, a gap is formed between the connecting plate 5 and the sidewall of the housing 4 on the side closest to the connecting plate 5. The gear 32 and the circular arc teeth 21 are both located within the gap, and the driver 31 is located on the side of the connecting plate 5 facing away from the gap. In other words, the driver 31 and gear 32 are located on either side of the connecting plate 5. Compared to having both driver 31 and gear 32 located on one side of the connecting plate 5, this provides greater stability. While the vehicle is in motion, the driver 31 will inevitably wobble, and the connecting plate 5 stabilizes the driver 31 and gear 32.

[0043] For specific implementation, refer to Figure 3 and Figure 4 Two sets of drive assemblies 3 are provided, one on each side of the radar body 1. Two connecting plates 5 are also provided, with each drive assembly 3 mounted on its corresponding connecting plate 5. Both sides of the radar body 1 are connected to the housing 4 via the drive assemblies 3 and connecting plates 5, making the radar body 1 more stable when extending into and out of the housing 4.

[0044] In practice, the base of the driver 31 is connected to one side of the connecting plate 5 via fasteners. The output shaft of the driver 31 passes through the connecting plate 5 and connects to the gear 32 located on the other side of the connecting plate 5. The arc teeth 21 are connected to the connecting plate 5 via a connecting shaft. Bearings are provided between the connecting shaft and the connecting plate 5 or between the arc teeth 21 and the connecting shaft. The connecting shaft can be a screw.

[0045] In some embodiments, along the extension direction of the connecting plate 5, the circular arc teeth 21 are located on the side of the gear 32 away from the top wall 42. This lowers the center of gravity of the rotating arm 2, making it more stable during rotation. Furthermore, given the limited space within the housing 4, the location of the circular arc teeth 21 below the gear 32 facilitates the rotating arm 2 avoiding the top wall 42 during rotation.

[0046] Considering the limited space inside the vehicle body for housing 4, in some embodiments, the shape of housing 4 matches the outer contour of radar body 1. When radar body 1 is located in the cavity within housing 4, the gap between the inner wall of housing 4 and the outer wall of radar body 1 is just sufficient to allow relative movement between them, thus preventing a larger gap from increasing the volume of housing 4 and occupying a larger space inside the vehicle body.

[0047] like Figures 1 to 3 As shown, in some embodiments, the edge of the opening of the shell 4 extends in a direction away from the cavity to form a first sealing portion 41, and the first sealing portion 41 is arranged around the opening of the shell 4 along the circumference of the shell 4. The edge of the top of the radar body 1 extends in a direction away from the cavity to form a second sealing portion 11, and the second sealing portion 11 surrounds the top edge of the radar body 1 along the circumference of the shell 4. Figure 1 , Figure 1 When the radar body 1 is fully inserted into the cavity of the housing 4, the first sealing portion 41 is configured to contact and connect with the second sealing portion 11. In other words, the first sealing portion 41 and the second sealing portion 11 form a seal, preventing debris such as fallen leaves from entering the housing 4.

[0048] Figure 2 The radar body 1 is extended out of the shell 4 and emits a laser beam for detection. The first sealing portion 41 can also block fallen leaves and other debris from falling into the shell 4 to a certain extent. In order to prevent fallen leaves and other debris from falling into the shell 4 through the gap between the radar body 1 and the shell 4 after the radar body 1 is extended out of the shell 4, in actual use, Figure 2 As shown, the bottom side of the front end of the radar body 1 is located in the cavity or opening of the housing 4 , that is, the maximum extent to which the radar body 1 extends out of the housing 4 is such that the bottom side of the front end is located in the opening of the housing 4 .

[0049] In some embodiments, the first sealing portion 41 extends away from the cavity to form a connecting portion 43 , which is used to bond to the inner side of the vehicle's front windshield 6 . The housing 4 is bonded to the front windshield 6 via the connecting portion 43 .

[0050] Considering the stability of the radar body 1 extending out of the housing 4 , drive assemblies 3 are provided on both sides of the radar body 1 .

[0051] On the other hand, the present application provides a vehicle, which includes the above-mentioned laser radar integrated device.

[0052] For specific implementation, refer to Figure 2 and Figure 6 The vehicle includes a front windshield 6 having an opening at its top. The housing 4 is located inside the front windshield 6, with the opening of the housing 4 partially overlapping the opening. The housing 4 is bonded to the front windshield 6 via a connecting portion 43. This provides a space inside the front windshield 6 that can accommodate the housing 4. Furthermore, when the radar body 1 extends out of the housing 4, it is positioned precisely at the junction of the front windshield 6 and the vehicle roof. This prevents interference from other parts of the vehicle body with the laser beam emitted by the front end of the radar body 1.

[0053] The laser radar integrated device is installed in the vehicle. The radar body 1 is extended to the outside of the vehicle body only when it needs to emit a laser beam. Under other circumstances, it is located inside the vehicle body, which will not affect the lines of the entire vehicle and will not increase the wind resistance of the vehicle when driving.
