The second connecting rod 40 is arranged perpendicular to the first connecting rod 30. The horizontal reference rod 50 is installed on the second connecting rod 40 and can rotate around the second connecting rod 40, and the horizontal plane where the center line along the length direction of the horizontal reference rod 50 is located is perpendicular to the center axis plane of the car. The laser 60 is movably mounted on the horizontal reference rod 50. The laser 60 is used to emit laser downward to form a laser line on an object under the laser 60.

[0056] It should be noted that the center axis plane of the automobile refers to a plane that is perpendicular to the ground and passes through the midpoints of the two front wheels and the two rear wheels of the automobile.

[0057] The energy transceiver surface of the radar assembly to be installed refers to: the antenna surface of the radar or a plane parallel to the antenna surface of the radar.

[0058] It can be understood that the side of the car includes the area below the rearview mirror of the car, or the side guardrail of the car.

[0059] Please also read Figure 3 and Figure 4In some embodiments, the first fixture 10 and the second fixture 20 may have the same structure and may both be wheel hub clamping devices. For example, the first fixture 10 includes a first mounting seat 110, two first claw assemblies 120, a first driving module 130 and a first locking module 140. The first mounting seat 110 is located at the center of the two first claw assemblies 120. The first end of the first connecting rod 30 is mounted on the first mounting seat 110. The two first claw assemblies 120 are clamped on the wheel hub of the front wheel. The two first claw assemblies 120 are mounted on the first driving module 130. The first driving module 130 is used to synchronously drive the two first claw assemblies 120 to move, so that the two first claw assemblies 120 can synchronously move toward or away from each other relative to the first mounting seat 110 to adapt to wheel hubs of different sizes. The first locking module 140 is used to lock the first driving module 130 to ensure that the two first claw assemblies 120 are fixed.

[0060] The second fixer 20 includes a second mounting seat 210, two second claw assemblies 220, a second driving module 230 and a second locking module 240. The second mounting seat 210 is located at the center position of the two second claw assemblies 220. The second end of the first connecting rod 30 is mounted on the second mounting seat 210. The two second claw assemblies 220 are clamped on the wheel hub of the rear wheel. The two second claw assemblies 220 are mounted on the second driving module 230. The second driving module 230 is used to synchronously drive the two second claw assemblies 220 to move, so that the two second claw assemblies 220 can synchronously move toward or away from each other relative to the second mounting seat 210 to adapt to wheel hubs of different sizes. The second locking module 240 is used to lock the second driving module 230 to ensure that the two second claw assemblies 220 are fixed.

[0061] The first driving module 130 and the second driving module 230 may be screw mechanisms, and the first driving module 130 is taken as an example for description.

[0062] For example, the first driving module 130 includes a guide assembly and a driving member 131 , wherein the guide assembly is used to guide the two first claw assemblies 120 to move, and the driving member 131 is used to synchronously drive the two first claw assemblies 120 to move closer to or away from each other.

[0063] Specifically, see Figure 5The driving member 131 may be a driving rod, including a left-handed threaded portion, a right-handed threaded portion and a connecting portion, wherein the connecting portion connects the left-handed threaded portion and the right-handed threaded portion, and the left-handed threaded portion and the right-handed threaded portion are arranged opposite to each other. The left-handed threaded portion is provided with a left-handed thread, and the right-handed threaded portion is provided with a right-handed thread. One of the first claw assemblies 120 is screwed to the left-handed threaded portion, and the other first claw assemblies 120 is screwed to the right-handed threaded portion. Thus, when the driving member 131 is rotated, the two first claw assemblies 120 move synchronously by the same distance to ensure that the first mounting seat 110 is always in the middle of the two first claw assemblies 120, and to ensure that the central axis of the first mounting seat 110 coincides with the central axis of its mounting hub.

[0064] The guide assembly includes a first guide column 132, a second guide column 133 and a connecting block 134, the first guide column 132 and the second guide column 133 are respectively located on both sides of the driving member 131, one first claw assembly 120 is installed at one end of the first guide column 132 and the second guide column 133, and the other first claw assembly 120 is installed at the other end of the first guide column 132 and the second guide column 133.

[0065] The driving member 131 is connected to the connecting block 134. Specifically, one end of the first guide column 132 passes through the two first claw assemblies 120 in sequence and is connected to the connecting block 134, and the other end of the first guide column 132 is connected to the locking module 140. Similarly, one end of the second guide column 133 passes through the two first claw assemblies 120 in sequence and is connected to the other end of the connecting block 134, and the first guide column 132 and the second guide column 133 are parallel to each other. Therefore, the two first claw assemblies 120 can move along the first guide column 132 and the second guide column 133 to ensure that the two first claw assemblies 120 move along the preset path.

[0066] One end of the driving member 131 is connected to the connecting block 134 , and the other end is connected to the locking module 140 .

[0067] It can be understood that in addition to the above-mentioned first guide column 132, second guide column 133 and connecting block 134, the guide assembly 210 can also be in the form of at least two pairs of sliders and two guide rails, for example, the slider is fixed on the first claw assembly, and the slider is slidably connected to the guide rail.

[0068] The embodiment of the present application does not impose any limitation on the structure of the first locking module 140 , as long as it can limit the rotation of the driving member 131 .

[0069] The first end of the first connecting rod 30 is installed on the first mounting seat 110, and the second end of the first connecting rod 30 is installed on the second mounting seat 210. Specifically, the first mounting seat 110 is provided with a first mounting hole for installing the first connecting rod 30, and the first mounting hole is coaxial with the central axis of the first mounting seat 110; the second mounting seat 210 is provided with a second mounting hole for installing the first connecting rod 30, and the second mounting hole is coaxial with the central axis of the second mounting seat 210, thereby ensuring that the vertical plane where the center line of the length direction of the first connecting rod 30 is located is parallel to the central axis plane of the automobile.

[0070] The first mounting hole and the second mounting hole may both be threaded holes, and threads may be respectively provided at both ends of the first connecting rod 30 , so that the first connecting rod 30 is fixed between the first mounting seat 110 and the second mounting seat 120 by cooperating with the first mounting hole and the second mounting hole.

[0071] Of course, the structures of the first fixture 10 and the second fixture 20 may also be different, as long as the first fixture 10 and the second fixture 20 can be snapped onto the wheel hub of the car, and the vertical plane where the center line along the length direction of the first connecting rod 30 is located is parallel to the center axis plane of the car.

[0072] In some embodiments, the second connecting rod 40 is mounted on the second mounting seat 120 and is perpendicular to the first connecting rod 30. In other embodiments, the second connecting rod 40 can be mounted on the ground or other devices, as long as the second connecting rod 40 is perpendicular to the first connecting rod 30, and this embodiment of the application does not impose any limitation on this.

[0073] In some embodiments, the horizontal reference rod 50 can only rotate around the second connecting rod 40, or the horizontal reference rod 50 can both rotate around the second connecting rod 40 and slide relative to the second connecting rod 40 along the length direction of the second connecting rod 40.

[0074] The horizontal reference rod 50 may be in an L-shaped, T-shaped or straight-line structure.

[0075] The present application takes the T-shaped horizontal reference rod 50 as an example for explanation.

[0076] See also Figure 6 The horizontal reference rod 50 includes a moving portion 510 and a rotating portion 520 extending vertically along the moving portion 510 . The moving portion 510 is sleeved on the second connecting rod 40 and can rotate around the second connecting rod 40 . The laser 60 is movably mounted on the rotating portion 520 .

[0077] It can be understood that when one end of the movable part 510 is a closed end and the other end is an open end, the movable part 510 is sleeved on the second connecting rod 40 and the closed end of the movable part 510 abuts against the top of the second connecting rod 40. At this time, the horizontal reference rod 50 can only rotate around the second connecting rod 40; when both ends of the movable part 510 are open ends, the movable part 510 is sleeved on the second connecting rod 40 and can slide along the second connecting rod 40. At this time, the horizontal reference rod 50 can both rotate around the second connecting rod 40 and slide relative to the second connecting rod 40 along the length direction of the second connecting rod 40.

[0078] This article takes the example that the horizontal reference rod 50 can both rotate around the second connecting rod 40 and slide relative to the second connecting rod 40 along the length direction of the second connecting rod 40 for explanation.

[0079] In some embodiments, the auxiliary positioning device includes a first locking mechanism 70, and the first locking mechanism 70 can lock the horizontal reference rod 50 relative to the second connecting rod 40 to limit the movement of the horizontal reference rod 50 relative to the second connecting rod 40.

[0080] It should be noted that limiting the movement of the horizontal reference rod 50 relative to the second connecting rod 40 means limiting the rotation and sliding of the horizontal reference rod 50 relative to the second connecting rod 40 .

[0081] The first locking mechanism 70 includes a locking ring, a first locking bolt and a first locking nut. The first locking ring is sleeved on the movable part 510. Both ends of the locking ring are provided with a first through hole and a first through hole for the first locking bolt to pass through. The first locking nut is used to cooperate with the first locking bolt after the first locking bolt passes through the first through hole and the first through hole.

[0082] When the first locking nut is tightened, the first locking mechanism 70 locks the horizontal reference rod 50; when the horizontal reference rod 50 needs to rotate or slide relative to the second connecting rod 40, the first locking bolt can be loosened.

[0083] It is worth noting that, in some embodiments, the first locking ring can be omitted, and the moving part is configured as an open-loop structure, and the open-loop structure constitutes the above-mentioned locking ring, such as Figure 7 shown.

[0084] It can be understood that the first locking mechanism 70 can also be other mechanisms. For example, the first locking mechanism includes two locking nuts, the outer surface of the connecting rod 40 is provided with a thread, and the two locking nuts are respectively screwed on the two ends of the connecting rod, and the movable part is located between the two nuts. When the two nuts are relatively tightened and abut against the movable part, the horizontal reference rod 50 can be locked. When the horizontal reference rod 50 needs to rotate or slide relative to the second connecting rod 40, the two locking nuts are loosened. At this time, the horizontal reference rod can rotate around the second connecting rod 40, and the horizontal reference rod can slide along the second connecting rod 40 between the two locking nuts.

[0085] It can be understood that the structural form of the first locking mechanism 70 is not limited to the embodiment of the present application, and other methods that can limit the rotation and sliding of the horizontal reference rod 50 are included in the embodiment of the present application.

[0086] In some embodiments, at the connection between the horizontal reference rod 50 and the second connecting rod 40, one of the horizontal reference rod 50 and the second connecting rod is provided with a first arc scale, and the other is provided with a first reference indicator line O2. For example, the moving portion 510 is provided with the first arc scale, and the second connecting rod 40 is provided with the first reference indicator line O2 (the first reference indicator line O2 may be a straight line located on the outer surface of the second connecting rod 40 and extending from the top of the second connecting rod to the bottom of the second connecting rod, such as Figure 6 As shown), when the horizontal reference rod 50 rotates relative to the second connecting rod 40, the rotation angle of the horizontal reference rod 50 can be known according to the first reference indication line O2 and the first arc scale on the moving part.

[0087] In some embodiments, a distance scale is provided on the first reference indication line O2, so that when the horizontal reference rod 50 slides relative to the second connecting rod 40, the sliding distance of the horizontal reference rod 50 can be known according to the distance scale on the first reference indication line O2.

[0088] It is understandable that the first reference indication line O2 may also be set on the moving part, and an arc scale is set on the second connecting rod 40. For easy observation, the arc scale extends from the top of the second connecting rod to the bottom of the second connecting rod.

[0089] By moving the horizontal reference rod 50 relative to the second connecting rod 40 , the horizontal angle of the laser 60 relative to the first connecting rod 30 can be adjusted.

[0090] The laser 60 is movably mounted on the horizontal reference rod 50 . In the embodiment of the present invention, the laser 60 is movably mounted on the horizontal reference rod 50 , which means that the laser 60 can rotate horizontally relative to the horizontal reference rod 50 .

[0091] For example, the laser 60 can rotate horizontally relative to the horizontal reference rod 50, and the auxiliary positioning device also includes a second locking mechanism 80, which is used to lock the laser 60 relative to the horizontal reference rod 50 to limit the movement of the laser 60 relative to the horizontal reference rod 50 (such as horizontal rotation).

[0092] The mechanism for horizontally rotating and locking the laser 60 relative to the horizontal reference rod 50 can be the same mechanism. For example, the second locking mechanism 80 includes a locking plate 81, a second locking bolt 82 and a second locking nut. The locking plate 81 is connected to the laser 60. The locking plate 81 is perpendicular to the central axis of the car. The locking plate 81 is provided with an arc hole 811 for the second locking bolt 82 to pass through. The horizontal reference rod 50 is provided with a slide groove 530 for the second locking bolt 82 to pass through. The second locking bolt 82 can slide along the slide groove 530. The slide groove 530 is arranged along the length direction of the horizontal reference rod 50. The second locking nut is used to cooperate with the second locking bolt 82 after the second locking bolt 82 passes through the arc hole 811 and the slide groove 530. Among them, the second locking bolt 82 can slide along the curvature direction of the arc-shaped hole 811, and the sum of the curvatures of the arc-shaped hole 811 is greater than or equal to 180 degrees. By sliding the second locking bolt 82 along the curvature direction of the arc-shaped hole 811, the horizontal angle of the laser 60 relative to the horizontal reference rod 50 can be adjusted.

[0093] When the second locking nut is tightened, the laser 60 can be locked relative to the horizontal reference rod 50. When the laser 60 needs to be rotated horizontally relative to the horizontal reference rod 50, the second locking nut can be loosened.

[0094] It can be understood that the connection between the laser 60 and the locking plate 81 can be a fixed connection or a movable connection, for example, the laser 60 is fixedly connected to the locking plate 81, or the laser 60 is movably connected to the locking plate 81, such as hinged. When the laser is movably connected (such as hinged) to the locking plate 81, the laser can move relative to the locking plate 81 only under the action of an external force.

[0095] In some embodiments, a second arc-shaped scale is provided on the arc-shaped hole 811, and a second reference indicator line is provided on the second locking bolt 82. The horizontal angle of rotation of the laser 60 relative to the horizontal reference rod 50 can be known through the second arc-shaped scale and the second reference indicator line on the arc-shaped hole 811.

[0096] In some embodiments, the laser 60 can also slide along the length direction of the horizontal reference rod 50. In order to limit the sliding of the laser 60 in other directions, the rotating portion 520 of the horizontal reference rod 50 is a square structure, and the locking plate 81 is parallel to the top surface of the rotating portion 520. A slider 90 is sleeved on the rotating portion 520, and the slider 90 can slide along the length direction of the horizontal reference rod 50. A second through hole for the second locking bolt 82 to pass through is provided on the slider 90. The second locking bolt passes through the arc hole, the second through hole and the slide groove 530 and then cooperates with the second locking nut. When the second locking nut is tightened, the locking plate 81 and the slider 90 remain relatively fixed, and the slider 90 can drive the second locking device 80 and the laser 60 to slide along the length direction of the horizontal reference rod 50.

[0097] It is worth noting that when the second locking nut is tightened, the second locking nut abuts against the sliding block.

[0098] To ensure that the slider is taken out from the top of the horizontal reference rod, one of the side surfaces of the horizontal reference rod and the side surface opposite to the side surface of the slider and the horizontal reference is provided with a convex rib, and the other is provided with a groove for accommodating the convex rib, and the convex rib can slide along the groove.

[0099] It can be understood that the slider 80 can slide along the length direction of the horizontal reference rod only under the action of external force.

[0100] In some other embodiments, the locking plate 81 may be omitted. Fig. 9 As shown, the second locking mechanism 80 includes a second locking bolt 82 and a second locking nut, and the laser 60 is mounted on the second locking bolt 82. The second locking bolt passes through the second through hole and the slide groove 530 and cooperates with the second locking nut. The horizontal angle of the laser 60 relative to the horizontal reference rod 50 can be adjusted by rotating the second locking bolt. In this way, at the connection between the second bolt 82 and the slider 90, one of the second locking bolt 82 and the slider 90 is provided with a second arc scale, and the other is provided with a second reference indicator line. Similarly, the laser 60 can be movably mounted on the second locking bolt 82 or fixedly mounted on the second locking bolt 82.

[0101] The laser 60 can slide along the horizontal reference rod 50 so that the laser emitted by the laser 60 can form a laser line on the first connecting rod 30, thereby preventing the laser 60 from being unable to form a laser line on the first connecting rod 30 due to the obstruction of the horizontal reference rod 50 when emitting laser downward.

[0102] Of course, in order to ensure that the laser emitted by the laser 60 can form a laser line on the first connecting rod 30 , the length of the first connecting rod must be greater than the length of the rotating portion 520 of the horizontal reference rod 50 .

[0103] It should be understood that the mechanism for moving and locking the laser 60 relative to the horizontal reference rod 50 is not limited to the embodiment of the present application, and other mechanisms that can move and lock the laser relative to the horizontal reference rod are included in the embodiment of the present application.

[0104] In specific implementation, loosen the second locking nut, rotate the laser 60 until the direction of the laser line of the laser 60 on the horizontal reference rod 50 is parallel to the center line of the length direction of the horizontal reference rod 50, tighten the second locking nut, and record the angle of the second reference indicator line relative to the second arc scale at this time, which is recorded as A1; loosen the first locking nut, rotate the horizontal reference rod 50 until the direction of the laser line of the laser emitted by the laser 60 on the first connecting rod 30 is parallel to the center line O1 of the length direction of the first connecting rod 30, tighten the second locking nut, record the angle of the first reference indicator line O2 relative to the first arc scale at this time as B1, and designate this position as Zero point position; obtain the installation angle and installation direction of the energy receiving and transmitting surface of the radar component to be installed relative to the central axis of the vehicle, loosen the second locking nut, horizontally rotate the laser 60 in the direction opposite to the installation direction by the installation angle, tighten the second locking nut, and record the angle of the second reference indicator line relative to the second arc scale at this time, recorded as A2; loosen the first locking nut, and then rotate the horizontal reference rod 50 until the laser line direction of the laser emitted by the laser 60 on the first connecting rod 30 is parallel to the center line of the length direction of the first connecting rod 30, tighten the second locking nut, and record the angle of the first reference indicator line O2 relative to the first arc scale at this time as B2.

[0105] At this time, the lateral position of the radar assembly to be installed on one side of the car can be determined according to the position of the horizontal reference rod 50 relative to the first connecting rod 30, that is, the angle of the energy receiving and transmitting surface of the radar assembly relative to one side of the car is determined.

[0106] It can be understood that the difference between A1 and A2 and the difference between B1 and B2 are both the installation angles.

[0107] In the above embodiment, the slider 90 can be slid as required.

[0108] Please also read Fig.10 and Fig.11 An auxiliary positioning method provided in an embodiment of the present application includes the above-mentioned auxiliary positioning device, which is used to assist in the installation of the above-mentioned radar component to be installed.

[0109] Step S10, adjusting the first fixture 10 and the second fixture 20 to ensure that the vertical plane where the center line along the length direction of the first connecting rod 30 is located is parallel to the center axis plane of the automobile;

[0110] Step S20, rotating the laser 60 until the direction of the laser line emitted by the laser on the horizontal reference rod 50 is parallel to the center line of the length direction of the horizontal reference rod;

[0111] Step S30, rotating the horizontal reference rod 50 until the direction of the laser line emitted by the laser 60 on the first connecting rod 30 is parallel to the center line of the length direction of the first connecting rod 30, and recording this position as the zero point position;

[0112] Step S40, obtaining an installation angle and an installation direction of an energy transceiver surface of the radar component to be installed relative to a central axis surface of the vehicle when the radar component to be installed is installed on one side of the vehicle;

[0113] It should be noted that the installation angle of the energy transceiver surface of the radar assembly to be installed relative to the center axis of the car refers to: the horizontal angle of the laser 60 relative to the first connecting rod 30. The installation direction of the energy transceiver surface of the radar assembly to be installed relative to the center axis of the car refers to: the deflection direction of the laser relative to the first connecting rod. Among them, the horizontal angle of the laser 60 relative to the first connecting rod 30 is the angle between the direction of the laser line emitted by the laser in the horizontal plane where the center line along the length direction of the first connecting rod 30 is located and the center line O1 along the length direction of the first connecting rod.

[0114] Step S50, according to the installation direction and the installation angle, adjust the horizontal reference rod 50 so that the angle between the horizontal reference rod 50 and the first connecting rod 30 is the same as the installation angle, and the deflection direction of the horizontal reference rod 50 relative to the first connecting rod 30 is the same as the installation direction.

[0115] It should be noted that the first connecting rod 30 and the adjusted horizontal reference rod 50 are used to assist in installing the radar component to be installed.

[0116] It should be noted that the step of adjusting the horizontal reference rod 50 according to the installation direction and the installation angle so that the angle between the horizontal reference rod 50 and the first connecting rod is the same as the installation angle further includes:

[0117] Step S510, horizontally rotating the laser 60 in a direction opposite to the installation direction by the installation angle;

[0118] Step S520, rotating the horizontal reference rod 50 until the direction of the laser line emitted by the laser 60 on the first connecting rod is parallel to the center line of the length direction of the first connecting rod.

[0119] The embodiment of the present invention provides an auxiliary positioning device and method, which can determine the installation position of the radar component to be installed on the side of one side of the car by adjusting the laser and the horizontal reference rod. The operation is simple, convenient and fast, and the installation accuracy is high.
