Abstract
Description
Technical Field
[0001] This application relates to the technical field of vehicle obstacle avoidance, and particularly to a sensor assembly and a vehicle. Background Art
[0002] In order to reduce the blind area during vehicle driving, the traditional treatment method is to fixedly install sensors such as radars around the vehicle body. For example, sensors can be installed on both the left and right sides in the forward direction of the vehicle or at the rear bumper of the vehicle to reduce the blind area range of the driver.
[0003] However, the detection range of sensors such as radars is limited and cannot basically cover the blind area range. Therefore, during the driving process of the vehicle, there is still a relatively large blind area. Summary of the Invention
[0004] Embodiments of this application provide a sensor assembly and a vehicle.
[0005] In a first aspect, this application provides a sensor assembly. The sensor assembly is installed on a vehicle and includes a mounting base, a sensor, and a motion mechanism. The mounting base is adapted to be installed on the vehicle and has a guiding portion whose extending direction is arc-shaped; the sensor is disposed on the mounting base; the motion mechanism is connected between the mounting base and the sensor, and the motion mechanism is used to be electrically connected to a controller of the vehicle and drive the sensor to move along the arc extending direction of the guiding portion according to a control instruction of the controller.
[0006] In a second aspect, this application also provides a vehicle. The vehicle includes a vehicle body, a controller, and the above-mentioned sensor assembly. The sensor assembly and the controller are disposed on the vehicle body, and both the sensor and the motion mechanism are electrically connected to the controller; when the vehicle is running, the motion mechanism drives the sensor to move according to a control instruction of the controller.
[0007] An embodiment of the present application provides a sensor assembly, which includes a sensor, a motion mechanism, and a mounting base. The sensor is disposed on the mounting base. The motion mechanism is connected between the mounting base and the sensor. The motion mechanism is electrically connected to a controller, and the motion mechanism can carry the sensor to move on the mounting base under the control instruction of the controller. Among them, a guiding portion is further provided on the mounting base in this embodiment. The guiding portion can cooperate with the motion mechanism and / or the sensor, thereby restricting the motion direction of the motion mechanism and the sensor, so that the motion mechanism and the sensor move along the extending direction of the guiding portion. The extending direction of the guiding portion in this embodiment is arc-shaped. Therefore, the sensor can define an arc-shaped motion trajectory during the motion process. It should be understood that the sensor moving on the arc-shaped motion trajectory means that the spatial angle of the sensor relative to the mounting base and the vehicle body changes, and the signal transceiver side of the sensor deflects relative to the vehicle body, so that the sensor can detect more space. Therefore, the detection range of the sensor becomes larger. The sensor assembly provided by this embodiment cooperates the motion mechanism with the arc-shaped guiding portion, so that the sensor moves on the arc-shaped motion trajectory, so that the blind area range that the sensor can detect is expanded, the blind area range during the vehicle driving process is reduced, and the obstacle avoidance ability of the vehicle is improved.

Detailed implementation manners
[0019] In order to enable those skilled in the art of this technology to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of this application.
[0020] Please refer to Figure 1 and Figure 2, this embodiment provides a vehicle 1000. The type of the vehicle 1000 can be a transportation vehicle such as a sedan, a truck, or a bus, or it can be a detection vehicle used for mining minerals or excavating tunnels. The vehicle 1000 in this embodiment includes a vehicle body 900 and a controller 800 for controlling the operation of the vehicle 1000. The controller 800 is disposed on the vehicle body 900 of the vehicle 1000, and the controller 800 can control the running speed and the running direction of the vehicle 1000. In the embodiment of the present application, the vehicle 1000 further includes a sensor assembly 100 disposed on the vehicle body 900. The sensor assembly 100 is used to detect risk factors that may affect the driving safety of the vehicle 1000 during driving. The sensor assembly 100 can be set at a position on the vehicle body 900 with a large blind area range, such as the tail of the vehicle body 900, or the front of the vehicle body 900 with a high chassis, which are structures prone to collision with obstacles. The sensor assembly 100 in this embodiment is electrically connected to the controller 800 to transmit information about the risk factors, such as the type of the risk factor, the orientation relative to the vehicle 1000, and the distance from the vehicle 1000, to the controller 800. The controller 800 can generate corresponding response instructions according to the information parameters of the risk factors to control the vehicle 1000 to avoid the risk factors or reduce the impact of the risk factors on the vehicle 1000.
[0021] Please refer to Figure 1 and Figure 2 , the sensor assembly 100 in this embodiment includes a sensor 10. The sensor 10 can detect risk factors. The type of the sensor 10 is not limited in this embodiment. For example, at least one of detection elements such as a radar, an infrared sensor, and a vision sensor can be selected. In this embodiment, an angular radar is selected as the sensor 10. In this embodiment, the sensor assembly 100 can be integrated into structures on the vehicle body 900 that are prone to collision with obstacles, such as the bumper or the vehicle headlamp of the vehicle body 900. As an example, the vehicle 1000 can include multiple sensor assemblies 100, and the multiple sensor assemblies 100 are respectively disposed on the left and right sides of the front bumper and the left and right sides of the rear bumper of the vehicle 1000. When the sensor assembly 100 is applied to some vehicles 1000 with a low chassis, the sensor assembly 100 can also be disposed on the side of the vehicle 1000 facing the ground.
[0022] Please refer to Figure 1 , Figure 2 and Figure 3, in this embodiment, the sensor 10 and the controller 800 are electrically connected to achieve the information interaction described above. The sensor assembly 100 in this embodiment further includes a motion mechanism 20, and the sensor 10 is mounted on the motion mechanism 20 and moves with the motion mechanism 20. Specifically, when the vehicle 1000 is traveling, the motion mechanism 20 drives the sensor 10 to move, and the sensor 10 defines an arc-shaped motion trajectory during the movement. As an example, the plane where the arc-shaped motion trajectory is located is parallel to the ground, so that the detection range of the sensor assembly 100 is on the same horizontal plane, and the information data detected by it is easier to process, reducing the calculation amount of the controller 800.
[0023] It should be understood that "the sensor 10 defines an arc-shaped motion trajectory during the movement, and the plane where the arc-shaped motion trajectory is located is parallel to the ground" means that the sensor 10 in this embodiment moves along an arc on a horizontal plane, and the sensor 10 can swing back and forth within a certain motion range around a specific axis or multiple axes to change the position of the sensor 10 on the vehicle 1000 and change the spatial angle between the signal transceiver side 11 of the sensor 10 and the vehicle body 900, so as to expand the detection range of the sensor 10. The expanded detection range is approximately the sum of the range that the sensor 10 itself has and the angle change of the sensor 10 relative to the vehicle 1000. Thus, the blind area range during the driving of the vehicle 1000 is effectively reduced.
[0024] In other embodiments, on the premise of ensuring that the signal transceiver side 11 of the sensor 10 faces the surrounding environment of the vehicle 1000, the plane where the arc-shaped motion trajectory of the sensor 10 is located can intersect with the ground. For example, when the sensor assembly 100 is applied to a relatively high van, it can be selected to deflect the signal transceiver side 11 of the sensor 10 towards the ground. As an example, when the sensor 10 moves along the arc-shaped motion trajectory, it has a rotation center line, which is the axis of rotation of the arc-shaped motion trajectory. The sensor assembly 100 in this embodiment can be inclined so that the sensor assembly 100 can scan and detect the environmental conditions in the vertical direction. For example, when the sensor assembly 100 is applied to a relatively high van, it can be selected to deflect the signal transceiver side 11 of the sensor 10 towards the ground. In this state, the rotation center line and the horizontal plane form a non-right angle, and the angle range is greater than or equal to 60° and less than 90°. Another example is that when the sensor assembly 100 is applied to a relatively low car, it can be selected to deflect the signal transceiver side 11 of the sensor 10 away from the ground. In this state, the rotation center line and the horizontal plane form a non-right angle, and the angle range is greater than or equal to 60° and less than 90°.
[0025] The motion mechanism 20 in this embodiment is electrically connected to the controller 800. In some actual application scenarios, when the vehicle 1000 is driving, the controller 800 can roughly judge the number of obstacles and the distribution of obstacles through the information transmitted by the sensor 10. The controller 800 can control the motion mechanism 20 to drive the sensor 10 to move, so that the sensor 10 and the signal transceiver side 11 move on the vehicle body 900 to an angle roughly corresponding to the obstacles or to an angle where the most obstacles can be detected, so as to improve the detection effect of the sensor assembly 100.
[0026] Please refer to Figure 2 、 Figure 3 and Figure 4 In this embodiment, the sensor assembly 100 may further include a mounting base 30 in addition to the motion mechanism 20 and the sensor 10 described above. The sensor is disposed on the mounting base, and the motion mechanism 20 is connected between the mounting base 30 and the sensor 10. The motion mechanism 20 is electrically connected to the controller 800, and the motion mechanism 20 is configured to carry the sensor 10 to move on the mounting base 30 under the control instruction of the controller 800. Among them, a guiding portion 31 is further provided on the mounting base 30 in this embodiment. The guiding portion 31 can cooperate with the motion mechanism 20 and / or the sensor 10, thereby restricting the moving directions of the motion mechanism 20 and the sensor 10, so that the motion mechanism 20 and the sensor 10 move along the extending direction of the guiding portion 31. The extending direction of the guiding portion 31 in this embodiment is arc-shaped. Therefore, under the guiding and restricting action of the guiding portion, the motion mechanism 20 drives the sensor 10 to move along an arc-shaped trajectory. Furthermore, the sensor 10 can form the arc-shaped motion trajectory described above during the movement process. It should be understood that when the sensor 10 moves on the arc-shaped motion trajectory, the spatial angle of the sensor 10 relative to the mounting base 30 and the vehicle body 900 changes, and the signal transceiver side 11 of the sensor 10 deflects relative to the vehicle body 900, so that the sensor 10 can detect more space. Therefore, the detection range of the sensor 10 becomes larger.
[0027] The sensor assembly 100 provided in this embodiment cooperates the motion mechanism 20 with the arc-shaped guiding portion 31, so that the sensor 10 moves on the arc-shaped motion trajectory, the blind area range that the sensor 10 can detect is enlarged, the blind area range during the driving process of the vehicle 1000 is reduced, and the obstacle avoidance ability of the vehicle 1000 is improved.
[0028] Please refer to again Figure 1, in some embodiments, the vehicle 1000 may further include a cover 700 for protecting the sensor assembly 100. Specifically, the cover 700 is connected to the vehicle body 900 and is disposed opposite to and spaced apart from the signal transceiver side 11 of the sensor 10, so as to substantially isolate the sensor assembly 100 from the external environment. In this embodiment, the cover 700 is arranged to extend along the arc-shaped movement track of the sensor 10 in the foregoing text, so as to fully protect the sensor assembly 100 and also enable the cover 700 to be substantially adapted to the outer surface of the vehicle body 900 to avoid local protrusion. In this embodiment, the cover 700 can be selected according to the type of the sensor 10. For example, in this embodiment, if the sensor 10 is a corner radar structure, the cover 700 can be a wave-transparent material such as glass, resin, etc. In some other embodiments, if the sensor 10 is a vision sensor, the cover 700 is a light-transmitting material such as transparent glass or transparent plastic.
[0029] Please refer to Figure 3 and Figure 4 , in this embodiment, the guiding portion 31 cooperates with the moving mechanism 20. Specifically, the guiding portion 31 is provided with an arc-shaped guiding groove 311, and a partial structure of the moving mechanism 20 is movably embedded in the arc-shaped guiding groove 311. When the moving mechanism 20 moves, it is restricted by the arc-shaped guiding groove 311, so that the moving mechanism 20 drives the sensor 10 to move along the arc-shaped extending direction of the arc-shaped guiding groove 311, thereby changing the spatial angle of the sensor 10 relative to the mounting base 30 and the vehicle body. In this embodiment, the arc-shaped guiding groove 311 guides the moving direction of the moving mechanism 20 and the sensor 10. The structure of the arc-shaped guiding groove 311 is simple, which can avoid increasing the number of components of the sensor assembly 100 and can also reduce the weight of the mounting base 30. In some other embodiments, the guiding portion 31 may include a rail structure provided on the mounting base 30, and the moving mechanism 20 is slidably matched with the rail structure.
[0030] Please refer to Figure 3 and Figure 4 , the moving mechanism 20 in this embodiment may include a mating member 21 and a moving member 22. Among them, the mating member 21 is disposed on the mounting base 30, and the moving member 22 is connected to the sensor 10 and is movably disposed on the mounting base 30 and is movably mated with the mating member 21, so that the moving member 22 carries the sensor 10 to move along the extending direction of the guiding portion 31. The sensor 10 is mounted on the moving member 22 to be able to move along with the moving member 22.
[0031] Please refer to Figure 3 and Figure 4, specifically, the mating part 21 in this embodiment includes a rack 211. The rack 211 is arranged on the mounting base 30, and the arrangement direction of the rack 211 is the same as the extending direction of the guiding part 31. The "arrangement direction" here should be understood as: there are a plurality of teeth 2111 on the rack 211, and the arrangement direction of the plurality of teeth 2111 is the same as the extending direction of the guiding part 31. Correspondingly, the moving part 22 in this embodiment includes a gear 221 and a rotary driving part 222. The sensor 10 is installed on the rotary driving part 222. The rotary driving part 222 includes an output shaft 2221, and the output shaft 2221 is connected to the gear 221 so that the rotary driving part 222 can output torque to the gear 221. Driven by the rotary driving part 222, the gear 221 can mesh with the teeth 2111 on the rack 211, so that the gear 221 can displace relative to the rack 211, and further change the positions of the rotary driving part 222 and the sensor 10 on the mounting base 30.
[0032] Please refer to Figure 4 and Figure 5 , in this embodiment, the guiding part 31 includes an arc-shaped guiding groove 311. At least part of the structure of the gear 221 is embedded in the arc-shaped guiding groove 311, and the rotation axis of the gear 221 is substantially perpendicular to the ground. Correspondingly, the shape of the rack 211 is also arc-shaped, and the rack 211 is arranged in parallel with the arc-shaped guiding groove 311. The rack 211 is arranged at the edge position of the notch of the arc-shaped guiding groove 311. A plurality of the above-mentioned teeth 2111 are arranged on the side of the rack 211 facing the arc-shaped guiding groove 311. The teeth 2111 extend towards the arc-shaped guiding groove 311, and at least part of the teeth 2111 are located above the notch of the arc-shaped guiding groove 311, so that the gear 221 in the arc-shaped guiding groove 311 can contact the teeth 2111 and mesh with the teeth 2111. In this embodiment, the arc-shaped guiding groove 311 can limit the movement path of the gear 221, so that the gear 221 can maintain a meshing fit relationship with the rack 211 to realize the movement of the gear 221, the rotary driving part 222 and the sensor 10 along the extending direction of the guiding part 31.
[0033] In other embodiments, the guiding part 31 includes an arc-shaped guiding groove 311. A mating key is provided on the side of the gear 221 facing the mounting base 30. The mating key protrudes along the rotation axis direction of the gear 221 relative to the gear 221, and the mating key is movably embedded in the arc-shaped guiding groove 311 to realize the guiding and limiting effects of the guiding part 31 on the gear 221.
[0034] In some other embodiments, the mating member 21 and the moving member 22 may also be of other structures. For example, the mating member 21 may include two roller shafts, which are respectively arranged at two ends in the extending direction of the arc-shaped guiding groove 311, and the rotation axes of the roller shafts are perpendicular to the ground. Among them, the rotation driving member 222 in this embodiment is connected to one of the roller shafts to drive the rotation of the roller shaft. Correspondingly, in this embodiment, the moving member 22 may further include a conveyor belt, and the sensor 10 is connected to the conveyor belt. The conveyor belt is sleeved on the outer peripheries of the two roller shafts, and the two roller shafts can tension the conveyor belt. The roller shafts rotate under the drive of the rotation driving member 222, thereby driving the conveyor belt and the sensor 10 to move. The movement mechanism 20 in this embodiment may further include an arc-shaped plate, and the arc-shaped side of the arc-shaped plate is attached to the conveyor belt so that the sensor 10 moves along an arc-shaped movement trajectory.
[0035] In other embodiments, the sensor assembly 100 may use an arc-shaped guide rail structure as the guiding portion 31 and a hydraulic driving structure or a pneumatic driving structure as the movement mechanism 20 to drive the sensor 10 to move on an arc-shaped movement trajectory and make the sensor 10 deflect at a spatial angle relative to the vehicle body 900.
[0036] Please refer to Figure 6 and Figure 7 , in this embodiment, the angle of the rotation angle B by which the movement mechanism 20 drives the sensor 10 to change relative to the vehicle body 900 can be specifically set with reference to the type of the sensor 10 and the detection range of the sensor 10. For example, in this embodiment, the sensor assembly 100 is arranged at a corner of the tail of the vehicle body 900, and the sensor assembly 100 can be arranged above or below the taillights on both sides of the tail of the vehicle body 900. The angle of the range to be detected at this position is approximately 270 degrees. When selecting an angle radar with an obstacle avoidance detection angle A of approximately 180 degrees as the sensor 10, the angle of the rotation angle B of the sensor 10 can be set between 80 degrees and 100 degrees. According to the foregoing, in the setting of this embodiment, the comprehensive detection range C (the sum of the obstacle avoidance detection angle A and the angle of the rotation angle B) of the sensor assembly 100 can reach about 270 degrees, so as to basically cover the angle of the range to be detected at a corner of the tail of the vehicle body 900 and reduce the impact of the blind area on the driving safety of the vehicle 1000.
[0037] Specifically, in this embodiment, the vehicle body 900 has a horizontal central axis M along its forward direction, and the sensor assembly 100 is located on one side of the central axis M in the horizontal direction. During the driving of the vehicle 1000, the sensor 10 moves along an arc-shaped movement trajectory. The sensor 10 in this embodiment has a first limit position and a second limit position on the arc-shaped movement trajectory. When the sensor 10 is in the first limit position, the range of the angle formed by the normal line L of the signal transceiver side 11 of the sensor 10 and the central axis M is approximately in [-30°, 30°]. When the sensor 10 moves from the first limit position to the second limit position, the signal transceiver side 11 of the sensor 10 rotates in a direction away from the central axis M, and the angle between the normal line L of the signal transceiver side 11 of the sensor 10 and the central axis M gradually increases until the sensor 10 reaches the second limit position. When the sensor 10 is in the second limit position, the angle formed by the normal line L of the signal transceiver side 11 of the sensor 10 and the central axis M is approximately in [70°, 130°]. Subsequently, the sensor 10 continues to swing towards the first limit position and cycles in turn. It should be understood that the rotation angle B is the angle between the normal line L when the sensor 10 is in the first limit position and the normal line L when the sensor 10 is in the second limit position, and the opening of the rotation angle B faces away from the vehicle body 900, so that during the rotation of the sensor 10, the signal transceiver side 11 faces the surrounding environment of the vehicle body 900. During the driving of the vehicle 1000 in this embodiment, the area covered by the comprehensive detection range C of the sensor assembly 100 includes the rear of the vehicle body 900 and one side of the vehicle body 900 in the forward direction.
[0038] In some other embodiments, according to the characteristics of the angular radar type sensor 10, an angular radar with a smaller obstacle avoidance detection angle A and a deeper obstacle avoidance detection depth can be selected, and at the same time, the angle of the rotation angle B is increased. On the one hand, it can ensure that the sum of the obstacle avoidance detection angle A and the rotation angle B can still cover the angle range that needs to be detected at a corner of the rear of the vehicle body 900, and on the other hand, it can improve the detection depth of the sensor assembly 100.
[0039] In other embodiments, other types of sensors 10 can be selected, such as vision sensors, infrared sensors, etc. The angle by which the motion mechanism 20 drives such sensors to change can be set with reference to the foregoing, and this embodiment will not be elaborated herein.
[0040] Please refer to Figure 5 and Figure 8, in this embodiment, the rotation driving member 222 includes a main body portion 2222 and the output shaft 2221 described above. The sensor 10 is mounted on the main body portion 2222, the output shaft 2221 is rotatably connected to the main body portion 2222, and the gear 221 is connected to the output shaft 2221 and is embedded in the arc-shaped guide groove 311. In order to achieve the meshing of the gear 221 and the rack 211 and thereby drive the rotation driving member 222 and the sensor 10 to move, it is necessary to keep the main body portion 2222 stationary relative to the output shaft 2221, that is, it is necessary to limit the rotation of the main body portion 2222 around the axis of the output shaft 2221. Therefore, in this embodiment, the mounting base 30 is provided with a first limiting portion 32, and a second limiting portion 12 is provided on the side of the sensor 10 close to the mounting base 30. The first limiting portion 32 and the second limiting portion 12 are movably nested and matched to limit the rotation of the sensor 10 and the main body portion 2222 relative to the mounting base 30 around the axis of the output shaft 2221. And the extending direction of the first limiting portion 32 is the same as the extending direction of the guiding portion 31, that is, the arc-shaped guide groove 311, and the second limiting portion 12 and the sensor 10 can move along the extending direction of the first limiting portion 32.
[0041] Please refer to Figure 5 and Figure 8 , in this embodiment, the first limiting portion 32 is a groove structure, and the extending direction of the groove-type first limiting portion 32 is the same as the extending direction of the guiding portion 31, that is, the arc-shaped guide groove 311. Correspondingly, the second limiting portion 12 in this embodiment is a convex block structure. In some other embodiments, the first limiting portion 32 is a strip-shaped limiting piece or a limiting plate structure, and the extending direction of the strip-shaped first limiting portion 32 is the same as the extending direction of the arc-shaped guide groove 311. Correspondingly, the second limiting portion 12 is a groove structure.
[0042] Please refer to Figure 2 and Figure 3 , the sensor assembly 100 in this embodiment may further include a cover body 40. The cover body 40 is cooperatively connected with the mounting base 30. The cover body 40 defines a receiving space 41. The moving mechanism 20 and the sensor 10 are arranged in the receiving space 41. The cover body 40 can protect the sensor 10 and the moving mechanism 20, prevent rain and snow from adhering to the sensor 10 and the moving mechanism 20, and reduce the influence of rainy and snowy weather on the sensor assembly 100.
[0043] In the present embodiment, the mounting base 30 is provided with a step 33. The step 33 extends along the edge of the mounting base 30 on the side facing the cover body 40. The cover body 40 can cover the step 33, and the outer peripheral surface of the step 33 is attached to the inner wall of the cover body 40, so that the positional relationship between the cover body 40 and the mounting base 30 is relatively stable, facilitating further fixing of the cover body 40 and the mounting base 30. In some embodiments, a plurality of dot grooves (not marked in the figure) are provided on the outer peripheral surface of the step 33. Correspondingly, a plurality of limiting dots (not marked in the figure) are provided on the inner wall of the cover body 40. The plurality of limiting dots and the plurality of dot grooves are arranged in one-to-one correspondence. When the cover body 40 is buckled on the mounting base 30, the limiting dots can be embedded into the corresponding dot grooves to initially connect the cover body 40 and the mounting base 30, and the effective cooperation between the cover body 40 and the mounting base 30 can also be judged according to the matching situation of the dot grooves and the limiting dots. In the present embodiment, the mounting base 30 and the cover body 40 can be fixedly connected by means of threaded connection, snap connection, etc.
[0044] In the present embodiment, a signal transceiver window 42 is provided on the cover body 40. The extending direction of the signal transceiver window 42 is the same as the extending direction of the guiding portion 31, i.e., the arc-shaped movement track. The signal transceiver window 42 is disposed opposite to the signal transceiver side 11 of the sensor 10, so as to allow the signals transmitted and received by the sensor 10 during movement to be transmitted via the signal transceiver window 42. In some other embodiments, a cable groove 43 can also be provided on the cover body 40 for the wires to pass through, so as to electrically connect the sensor 10, the rotary driving member 222, the controller 800, etc.
[0045] The material of the cover body 40 in the present embodiment is not limited and can be specifically selected according to the type of the sensor 10. For example, in some embodiments, when the sensor 10 is a radar, the material of the cover body 40 can be selected as a plastic material with wave-transmitting performance. In this embodiment, the signal transceiver window 42 may not be provided on the cover body 40.

The first engaging portion 34 and the third engaging portion 13 are movably engaged, and the second engaging portion 44 and the fourth engaging portion 14 are movably engaged. It can be understood that the mounting base 30 and the cover body 40 jointly clamp the sensor 10 to jointly limit the movement of the sensor 10 along the axial direction of the arc-shaped movement track. Among them, the extending directions of the first engaging portion 34 and the second engaging portion 44 are the same as the extending direction of the guiding portion 31, i.e., the arc-shaped guiding groove 311, so that the sensor 10 can move along the extending direction of the guiding portion 31.

That is, the first mating portion 34 can be a groove structure extending, and correspondingly, the third mating portion 13 is a bump structure; or, the first mating portion 34 can be a strip-shaped plate wall structure extending, and correspondingly, the third mating portion 13 is a groove structure. The second mating portion 44 can be a groove structure extending, and correspondingly, the fourth mating portion 14 is a bump structure; or, the second mating portion 44 can be a strip-shaped plate wall structure extending, and correspondingly, the fourth mating portion 14 is a groove structure. In this embodiment, the first mating portion 34 and the first limiting portion 32 have the same structure, and the third mating portion 13 and the first limiting portion 12 have the same structure.
[0048] Please refer to Figure 9 , the sensor assembly 100 in this embodiment further includes a mounting bracket 50, and the mounting bracket 50 is used to connect the sensor 10 and the motion mechanism 20. Specifically, the mounting bracket 50 in this embodiment includes a protection portion 51 and a mounting portion 52 which are connected. The protection portion 51 in this embodiment is used to cover a part of the structure of the sensor 10 to improve the impact resistance of the sensor 10, and can expose the signal transceiver side 11 of the sensor 10. Specifically, the protection portion 51 has a protection cavity 511, and the protection cavity 511 communicates with the outside and forms a mounting port 512. The sensor 10 can be mounted into the protection cavity 511 through the mounting port 512, and the mounting port 512 corresponds to the signal transceiver side 11 of the sensor 10 to expose the signal transceiver side 11. In some embodiments, the protection portion 51 is a structure with elastic deformation ability, such as rubber, plastic, etc.
[0049] As can be seen from the foregoing text, structures such as the second limiting portion 12, the third mating portion 13, and the fourth mating portion 14 are provided on the sensor in this embodiment. In this embodiment, the second limiting portion 12, the third mating portion 13, and the fourth mating portion 14 are all bump structures. Correspondingly, the first limiting portion 32, the first mating portion 34, and the second mating portion 44 are all groove structures. The protection portion 51 in this embodiment is provided with hollow portions at multiple positions, so that the bump structures can pass through the protection portion 51 and extend to the outside of the protection cavity 511, so that the bump structures can cooperate with the groove structures.
[0050] In this embodiment, the mounting portion 52 is cooperatively connected with the motion mechanism 20 to connect the sensor 10 and the motion mechanism 20 into an integral structure, so that the sensor 10 can move along the extension direction of the guiding portion 31 following the motion mechanism 20. In this embodiment, the mounting portion 52 can be connected to the main body portion 2222 of the rotary driving member 222 through a mating connection structure such as a snap and a slot. In some other embodiments, the mounting portion 52 can be a cover structure, and the cover-type mounting portion 52 covers the main body portion 2222 to achieve the connection.
[0051] This embodiment provides a sensor assembly 100, which includes a sensor 10, a motion mechanism 20, and a mounting seat 30. The sensor 10 is disposed on the mounting seat 30. The motion mechanism 20 is connected between the mounting seat 30 and the sensor 10, and the motion mechanism 20 is electrically connected to the controller 800 of the vehicle 1000. The motion mechanism 20 can carry the sensor 10 to move on the mounting seat 30 under the control instruction of the controller 800. Among them, a guiding portion 31 is further disposed on the mounting seat 30 in this embodiment. The guiding portion 31 can cooperate with the motion mechanism 20 and / or the sensor 10, and further limit the motion directions of the motion mechanism 20 and the sensor 10, so that the motion mechanism 20 and the sensor 10 move along the extension direction of the guiding portion 31. The extension direction of the guiding portion 31 in this embodiment is arc-shaped. Therefore, the sensor 10 can define an arc-shaped motion trajectory during the motion process. It should be understood that the movement of the sensor 10 along the arc-shaped motion trajectory means that the spatial angle of the sensor 10 relative to the mounting seat 30 and the vehicle body 900 changes, and the signal transceiver side 11 of the sensor 10 deflects relative to the vehicle body 900, so that the sensor 10 can detect more space. Therefore, the detection range of the sensor 10 becomes larger. The sensor assembly 100 provided in this embodiment enables the sensor 10 to move along the arc-shaped motion trajectory through the motion mechanism 20, so that the blind area range that the sensor 10 can detect is expanded, the blind area range during the driving of the vehicle 1000 is reduced, and the obstacle avoidance ability of the vehicle 1000 is improved.
