Abstract
Description
Technical Field
[0001] This application belongs to the field of automotive design technology, and in particular relates to a lidar system and driving equipment. Background Technology
[0002] LiDAR has a wide range of applications, including autonomous vehicles, industry, drones, and robotics, with automotive LiDAR accounting for the largest share. The primary function of LiDAR is to act as the "eyes" of driving equipment, perceiving the objects around the vehicle. LiDAR works by emitting laser pulse signals towards a target, receiving the echo signals reflected back from the target, comparing and processing the echo signals with the pulse signals to obtain information about the target object.
[0003] Installing lidar above the front and rear bumpers is one of the mainstream deployment solutions for mass-produced driving equipment. However, since the lidar is positioned relatively low above the front and rear bumpers relative to the overall vehicle height, it is easily damaged in the event of a traffic accident. Even a minor rear-end collision can cause lidar malfunction, leading to issues with the safety and reliability of the driving equipment. Utility Model Content
[0004] The purpose of this application is to provide a lidar system and driving equipment, which aims to solve the problem that lidar located above the front and rear bumpers of the driving equipment is easily damaged in the event of a rear-end collision or other collision.
[0005] To achieve the above objectives, according to the first aspect of this application, the technical solution adopted by this application is: a lidar system, including a mounting assembly and a lidar mounted on the mounting assembly, the mounting assembly comprising:
[0006] The slide rail component includes a guide rail and a support component fixedly connected to the guide rail;
[0007] The slider is slidably mounted on the guide rail, and the laser radar is fixedly mounted on the slider. The slider has at least a first station and a second station on the guide rail, and the first station and the second station are spaced apart along the extension direction of the guide rail.
[0008] The control unit is connected in communication with the lidar.
[0009] The drive mechanism is connected to the control unit and to the slider drive. The drive mechanism is used to drive the slider to reciprocate between the first station and the second station along the extension direction of the guide rail.
[0010] The lidar system of this application is installed on the vehicle body assembly of the driving device, for example, above the front bumper. When the driving device is driving normally on the road, the slider is in the first position, that is, the lidar is in the first position. The lidar can detect the close-range area and low objects in front of the driving device. When the driving device is involved in a rear-end collision or hits an obstacle in front, the lidar of this application's lidar system will detect and predict the risk of collision before the collision occurs. Then, the lidar sends a signal to the control unit. When the control unit receives the signal sent by the lidar, it controls the drive mechanism to start. The drive mechanism drives the slider and the lidar together to move quickly to the second position, so that the lidar is spared from collision or the impact force on the lidar is reduced, thereby protecting the lidar and reducing the risk of damage to the lidar.
[0011] In some embodiments of this application, the control unit is mounted on the slider or slide rail component, and the drive mechanism includes a motor and a roller. The motor is fixedly mounted on the slider and electrically connected to the control unit. The roller is connected to the motor's shaft and abuts against the guide rail. The rotation of the roller generates friction with the guide rail, causing the roller to move relative to the guide rail along the extension direction of the guide rail. This drives the motor, slider, and laser radar to reciprocate between the first and second workstations along the extension direction of the guide rail.
[0012] In some embodiments of this application, the drive mechanism includes N motors and N rollers, with each of the N motors and N rollers connected in a one-to-one correspondence. The N rollers are symmetrically arranged with respect to the extension direction of the guide rail, and the N rollers rotate synchronously, where N is an even number. The N rollers form multi-point contact with the guide rail, and these multiple contact points are symmetrically distributed with respect to the extension direction of the guide rail, thereby ensuring that the rollers, motors, sliders, and the lidar as a whole remain stable relative to the guide rail.
[0013] In some embodiments of this application, the driving mechanism includes an electromagnet structure, a magnetic attractor, and a return spring. The electromagnet structure is electrically connected to the control unit and is fixedly installed at the second end of the guide rail. The magnetic attractor is fixedly installed on the slider and is positioned opposite to the electromagnet structure. One end of the return spring is connected to the first end of the guide rail, and the other end of the return spring is connected to the slider. The first end of the guide rail is the end closer to the first workstation, and the second end of the guide rail is the end closer to the second workstation. When the driving device experiences a rear-end collision or hits an obstacle ahead, the control unit controls the electromagnet structure to be energized to generate an electromagnetic field, which in turn generates a magnetic attraction force on the magnetic attractor, thereby driving the laser radar to move rapidly from the first workstation to the second workstation along the extension direction of the guide rail. When it can be determined that the laser radar is in a safe situation (the collision has ended or the distance between the driving device and the obstacle ahead is greater than or equal to a safe distance), the control unit controls the electromagnet structure to be de-energized, causing the electromagnetic field to fail. Under the elastic force of the return spring, the laser radar resets and moves from the second workstation to the first workstation along the extension direction of the guide rail.
[0014] In some embodiments of this application, the drive mechanism includes a motor and a screw. The motor is fixedly mounted on the slide rail component and electrically connected to the control unit. The motor shaft is driven by the screw. The slide rail has a threaded through hole, and the screw passes through and is screwed into the threaded through hole. When the driving device experiences a rear-end collision or collides with an obstacle directly in front, the control unit controls the motor to start, driving the screw to rotate forward, thus moving the laser radar quickly from the first station to the second station. When the collision ends or it can be determined that the laser radar is in a safe situation, the control unit controls the motor to drive the screw to rotate in reverse, thereby moving the laser radar quickly back to the first station from the second station.
[0015] In some embodiments of this application, the lidar system further includes a domain controller, which is electrically connected to both the control unit and the lidar.
[0016] In some embodiments of this application, the slider has multiple heat dissipation holes, the bottom surface of the lidar is covered with multiple heat dissipation holes, and the multiple heat dissipation holes are arranged circumferentially along the bottom surface of the lidar to improve the heat dissipation capacity of the lidar and enable the operating temperature of the lidar to be stably maintained within a suitable range.
[0017] In some embodiments of this application, the guide rail is provided with screw holes for screws to be threaded onto the support.
[0018] In some embodiments of this application, the sidewall of the guide rail that contacts the slider is provided with a groove. Multiple grooves are arranged linearly along the extension direction of the guide rail, which reduces the contact area between the bottom surface of the slider and the guide rail, thereby reducing the friction between the slider and the guide rail.
[0019] According to a second aspect of this application, a driving device is provided. The driving device includes a vehicle body assembly and the aforementioned lidar system. The lidar system is mounted on the vehicle body assembly, which includes a front bumper or a rear bumper. A support member of a sliding rail component is fixedly connected to the front or rear bumper. When the driving device is normally driving on the road, the slider is in a first position, i.e., the lidar is in the first position, and the lidar can scan an area very close to the ground directly in front of the driving device. When the driving device is involved in a rear-end collision or collides with an obstacle directly in front, the lidar system of this application detects and predicts the risk of collision before the collision occurs. The lidar then sends a signal to the control unit. Upon receiving the signal from the lidar, the control unit controls the drive mechanism to start, thereby driving the slider and the lidar together to move quickly to a second position. This avoids the lidar colliding with the obstacle or reduces the impact force, thus protecting the lidar and reducing the risk of damage. Attached Figure Description

[0041] LiDAR (Light Detection and Ranging) is a sensor that detects the surrounding environment by emitting laser beams and is commonly used in autonomous vehicles. For structural compatibility and aesthetic reasons, LiDAR systems are typically installed on the front and rear bumpers of vehicles. The bumpers usually have ample space for integrating the LiDAR and its mounting structure, and their proximity to the vehicle's electrical system facilitates wiring, making the LiDAR appear unobtrusive while complying with vehicle safety regulations. Furthermore, the bumper's location at the vehicle's edge allows for maximum horizontal field of view, covering a large area in front of or behind the vehicle, reducing blind spots, especially in low-speed scenarios where it effectively detects low obstacles (such as curbs, children, and pets). However, the area above the bumper is susceptible to vibration and impacts, which can damage the LiDAR, weakening the driver's perception capabilities, degrading or disabling some functions, and significantly increasing safety risks. Moreover, LiDAR is relatively expensive, requires specialized calibration equipment, and has a long replacement cycle. Damage to the LiDAR during a collision can result in high repair costs and a poor driving experience for the owner. Therefore, this application proposes a lidar system and driving equipment, aiming to solve the problem that lidar located above the front and rear bumpers of the driving equipment is easily damaged in the event of a rear-end collision or other impact.
[0042] According to the first aspect of this application, Figures 1 to 6 As shown, the lidar system 100 provided in the embodiments of this application includes a mounting assembly and a lidar 200 mounted on the mounting assembly. The mounting assembly includes a slide rail component 10, a slider 20, a control unit 30, and a drive mechanism 40. The slide rail component 10 includes a guide rail 11 and a support member 12 fixedly connected to the guide rail 11. The slider 20 is slidably disposed on the guide rail 11, and the lidar 200 is fixedly mounted on the slider 20. Specifically, the slider 20 has a mounting hole 23, and the lidar 200 is locked on the slider 20 by bolts. The slider 20 has at least a first station 21 and a second station 22 on the guide rail 11. The first station 21 and the second station 22 are spaced apart along the extension direction of the guide rail 11. The control unit 30 is communicatively connected to the lidar 200, and the drive mechanism 40 is communicatively connected to the control unit 30. Specifically, the connection between the control unit 30 and the lidar 200, and between the control unit 30 and the drive mechanism 40, can be wired or wireless. When wireless communication is used, the control unit 30 can be installed at any position on the vehicle body, on the guide rail 11, or on the slider 20. The drive mechanism 40 is drively connected to the slider 20 and is used to drive the slider 20 to reciprocate between the first station 21 and the second station 22 along the extension direction of the guide rail 11.
[0043] The lidar system 100 of this application is installed on the vehicle body assembly 300 of the driving device, for example, above the front bumper. When the driving device is driving normally on the road, the slider 20 is located at the first station 21, that is, the lidar 200 is located at the first station 21. The lidar 200 can detect obstacles in front of the driving device and near-field blind spots. When the driving device is involved in a rear-end collision or collides with an obstacle in front, the lidar 200 of the lidar system 100 of this application will detect and predict the risk of collision before the collision occurs. Then, the lidar 200 sends a signal to the control unit 30. When the control unit 30 receives the signal sent by the lidar 200, it controls the drive mechanism 40 to start. The drive mechanism 40 drives the slider 20 and the lidar 200 to move quickly to the second station 22, so that the lidar 200 avoids colliding with obstacles or reduces the impact force, thereby protecting the lidar 200 and reducing the risk of damage to the lidar 200.
[0044] In some embodiments of this application, such as Figure 2 As shown, the control unit 30 is mounted on the slider 20. In this case, the control unit 30 moves reciprocally between the first station 21 and the second station 22 along the extension direction of the guide rail 11, together with the slider 20. In other embodiments, the control unit 30 is mounted on the slide rail component 10. In this case, the control unit 30 is relatively stationary relative to the guide rail 11, and the drive mechanism 40 drives the slider 20 to move reciprocally between the first station 21 and the second station 22 relative to the guide rail 11. That is, the slider 20 moves reciprocally between the first station 21 and the second station 22 relative to the control unit 30.
[0045] In some embodiments, such as Figure 3As shown, the drive mechanism 40 includes a motor 41 and a roller 42. The motor 41 is fixedly mounted on the slider 20 and is electrically connected to the control unit 30. The roller 42 is connected to the rotating shaft of the motor 41 and abuts against the guide rail 11. Thus, when the control unit 30 receives a signal sent by the laser radar 200, the control unit 30 controls the motor 41 to start, and then the motor 41 drives the roller 42 to rotate. Since the roller 42 abuts against the guide rail 11, friction is generated between the roller 42 and the guide rail 11, causing the roller 42 to move relative to the guide rail 11 along the extension direction of the guide rail 11. This drives the motor 41, the slider 20, and the laser radar 200 to reciprocate between the first station 21 and the second station 22 along the extension direction of the guide rail 11. In this way, when the driving device is involved in a rear-end collision or hits an obstacle directly in front, the lidar 200 will detect and predict the risk of collision before the collision occurs. Then, the lidar 200 sends a signal to the control unit 30. Upon receiving the signal sent by the lidar 200, the control unit 30 controls the motor 41 to start and drive the roller 42 to rotate. This causes the motor 41, the slider 20, and the lidar 200 to move quickly from the first station 21 to the second station 22, so that the lidar 200 is away from the collision point. This avoids the lidar 200 being hit by a collision or reduces the impact force on the lidar 200, thereby protecting the lidar 200 and reducing the degree of collision damage.
[0046] In order for the roller 42, motor 41, slider 20 and laser radar 200 to move stably relative to the guide rail 11, such as Figure 3 As shown, in some embodiments, the drive mechanism 40 includes N motors 41 and N rollers 42, with each of the N motors 41 and N rollers 42 connected in a one-to-one correspondence. The N rollers 42 are symmetrically arranged with respect to the extension direction axis of the guide rail 11, and the N rollers 42 rotate synchronously, where N is an even number. That is, the N rollers 42 form multi-point contact with the guide rail 11, and the multiple contact points are symmetrically distributed with respect to the extension direction axis of the guide rail 11, thereby ensuring that the rollers 42, motors 41, slider 20, and lidar 200 as a whole remain stable relative to the guide rail 11.
[0047] In other embodiments of this application, such as Figure 5 and Figure 6As shown, the drive mechanism 40 includes an electromagnet structure 43, a magnetic attractor 44, and a return spring 45. The electromagnet structure 43 is fixedly mounted on the second end of the guide rail 11. The magnetic attractor 44 is fixedly mounted on the slider 20 and is positioned opposite to the electromagnet structure 43. One end of the return spring 45 is connected to the first end of the guide rail 11, and the other end of the return spring 45 is connected to the slider 20. The control unit 30 is mounted on the slider 20, or the control unit 30 is mounted on the slide rail component 10. The electromagnet structure 43 is electrically connected to the control unit 30. The first end of the guide rail 11 is the end of the guide rail 11 closest to the first station 21, and the second end of the guide rail 11 is the end of the guide rail 11 closest to the second station 22. When the driving device is involved in a rear-end collision or hits an obstacle directly in front, the lidar 200 will detect and predict the risk of collision before the collision occurs. Then, the lidar 200 sends a signal to the control unit 30. Upon receiving the signal from the lidar 200, the control unit 30 controls the electromagnet structure 43 to be energized to generate an electromagnetic field, which generates a magnetic attraction force on the magnetic suction member 44. This causes the magnetic suction member 44, the slider 20, and the lidar 200 to move quickly along the extension direction of the guide rail 11 from the first station 21 to the second station 22, so that the lidar 200 is away from the collision point and overcomes the elastic force of the return spring 45 to stretch the return spring 45. This allows the lidar 200 to avoid colliding with the obstacle or reduce the impact force of the obstacle on the lidar 200, thereby protecting the lidar 200 and reducing the risk of damage to the lidar 200. When it can be determined that the lidar 200 is in a safe situation (the collision has ended or the distance between the driving equipment and the obstacle in front is greater than or equal to the safe distance), the control unit 30 controls the electromagnet structure 43 to de-energize, so that the electromagnetic field is disabled. In this way, the magnetic suction component 44, the slider 20 and the lidar 200 move together from the second station 22 to the first station 21 along the extension direction of the guide rail 11 under the elastic force of the return spring 45.
[0048] In some other embodiments of this application, the drive mechanism 40 includes a motor 41 and a screw. The motor 41 is fixedly installed on the slide rail component 10. The motor 41 is electrically connected to the control unit 30. The rotating shaft of the motor 41 is drivenly connected to the screw. The slider 20 is provided with a threaded through hole. The screw passes through the threaded through hole and is screwed into the threaded through hole. That is, the screw and the slider 20 are assembled to form a screw-nut transmission pair. In other words, when the driving device is involved in a rear-end collision or hits an obstacle directly in front, the lidar 200 will detect and predict the risk of collision before the collision occurs. The lidar 200 then sends a signal to the control unit 30. Upon receiving the signal from the lidar 200, the control unit 30 controls the motor 41 to start, driving the screw to rotate forward. Since the screw is screwed into the threaded through hole and the slider is guided and limited by the guide rail, the motor 41, slider 20, and lidar 200 move quickly from the first station 21 to the second station 22, moving the lidar 200 away from the point of collision. This avoids collisions with obstacles or reduces the impact force of the obstacles on the lidar 200, thus protecting it. When it is determined that the lidar 200 is in a safe situation, the control unit 30 controls the motor 41 to reverse, causing the motor 41, slider 20, and lidar 200 to quickly return from the second station 22 to the first station 21.
[0049] In the lidar system 100, the control unit 30 includes a domain controller (also known as an advanced driver assistance system, or ADAS; or ADAS domain controller system), which is electrically connected to the control unit 30 and the lidar 200. When a rear-end collision or an obstacle occurs, the entire lidar system 100 will handle the situation in four ways: First, in terms of perception, the lidar 200 collects the distance and relative speed information of the obstacle in real time and calculates and predicts the time of possible collision through the ADAS domain controller system; second, in the analysis layer, the ADAS domain controller system analyzes the acquired data and determines that if the calculated collision time is lower than a certain threshold, a collision may occur; then, in the decision layer, the ADAS domain controller system issues an obstacle collision warning to the control unit 30, and the control unit 30 sends a message to the drive mechanism 40 to drive the slider 20 to move the lidar 200 to the second station 22; finally, in the execution layer, the drive mechanism 40 receives the message from the control unit 30 and starts, thereby causing the slider 20 to move the lidar 200 quickly along the guide rail 11 to the second station 22, that is, the lidar 200 reaches the predetermined safe position, protecting the internal components of the lidar 200 from impact and reducing the risk of damage to the lidar 200.
[0050] In the lidar system 100 provided in the embodiments of this application, the lidar 200 continuously generates heat during the detection process. To improve the heat dissipation capacity of the lidar 200 and ensure its operating temperature is stably maintained within a suitable range, such as... Figure 4 As shown, the slider 20 has multiple heat dissipation holes 24, and the bottom surface of the lidar 200 covers these holes. The bottom surface of the lidar 200 rests against the surface of the slider 20, and the multiple heat dissipation holes 24 are arranged circumferentially along the bottom surface of the lidar 200. In this way, the heat generated by the lidar 200 is transferred to the slider 20 to dissipate heat and cool it down. Furthermore, the multiple heat dissipation holes 24 on the slider 20 facilitate the dissipation of heat from the lidar 200 into the air, thereby accelerating the cooling process and ensuring that the operating temperature of the lidar 200 is stably maintained within a suitable range.
[0051] In some embodiments, the guide rail 11 is provided with screw holes for screws to be screwed onto the support member 12. That is, after the screw passes through the screw holes of the guide rail 11, it is screwed onto the support member 12, thereby fixing the guide rail 11 to the support member 12.
[0052] In some embodiments, such as Figure 5 As shown, the side wall of the guide rail 11 that contacts the slider 20 is provided with a recess 111, and multiple recesses 111 are arranged linearly along the extension direction of the guide rail 11. Each recess 111 corresponds to a screw hole, and the recesses 111 and screw holes are coaxially arranged. Thus, when a screw passes through the screw hole and is screwed onto the support 12, the screw head sinks into the recess 111, causing the screw head to avoid the slider 20. This reduces the contact area between the bottom surface of the slider 20 and the guide rail 11, thereby reducing the friction between the slider 20 and the guide rail 11, allowing the slider 20 to move smoothly and stably relative to the guide rail 11.
[0053] According to another aspect of this application, a driving device is provided. This driving device includes a vehicle body assembly 300 and the aforementioned lidar system 100. The lidar system 100 is mounted on the vehicle body assembly 300, which includes a front bumper or a rear bumper. The support member 12 of the slide rail component 10 is fixedly connected to the front bumper or the rear bumper. Figure 7 and Figure 8As shown. When the driving device is driving normally on the road, the slider 20 is located at the first station 21, that is, the lidar 200 is located at the first station 21, and the lidar 200 can scan the field of view in front of the driving device. When the driving device is involved in a rear-end collision or collides with an obstacle in front, the lidar 200 of the lidar system 100 of this application will detect and predict the risk of collision before the collision occurs. Then, the lidar 200 sends a signal to the control unit 30. When the control unit 30 receives the signal sent by the lidar 200, it controls the drive mechanism 40 to start. The drive mechanism 40 drives the slider 20 and the lidar 200 to move quickly to the second station 22, so that the lidar 200 avoids colliding with the obstacle or reduces the collision force, thereby protecting the lidar 200 and reducing the degree of collision damage to the lidar 200.
[0054] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
