Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular, to an optical calibration bracket and a vehicle calibration device. Background Art

[0002] Automated driving of automobiles is the trend of the future, and ADAS (Advanced Driving Assistance System) is the necessary path for automobiles to achieve automated driving. Initially, ADAS technology was applied to luxury cars. Due to the gradual maturity of the technology and the trend of decreasing product prices, automobile manufacturers have gradually penetrated into mid-range cars and small cars. It is estimated that in the future, the number of automobiles equipped with ADAS technology globally will be extremely large. Therefore, the automobile aftermarket also needs to launch ADAS calibration services to help users successfully complete the calibration of radars and cameras, restore the normal function of ADAS, and ensure the driving safety of users.

[0003] Before performing ADAS calibration, it is usually necessary to calibrate the longitudinal center line of the vehicle. After calibrating the longitudinal center line of the vehicle, it is also necessary to adjust the horizontal slide rail on the calibration bracket to ensure that the horizontal slide rail is perpendicular to the longitudinal center line of the vehicle, and then use the mounting tool on the horizontal slide rail to calibrate the radar and camera. In the related art, after calibrating the longitudinal center line of the vehicle, the inventor found that it is very difficult to adjust the horizontal slide rail on the calibration bracket to be perpendicular to the longitudinal center axis of the vehicle. The operation is cumbersome, and it is difficult to ensure the perpendicularity of the adjusted horizontal slide rail to the longitudinal center axis of the vehicle. In addition, the calibration bracket is not easy to adjust and cannot adapt to different vehicle models and detection sites. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems in the related art to some extent. For this purpose, an object of the present invention is to provide an optical calibration bracket.

[0008] A lifting seat movably arranged on the moving frame in the vertical direction;

[0009] An optical alignment member slidably arranged on the lifting seat in the horizontal direction, the optical alignment member having a pair of optical holes for a laser beam to pass through;

[0010] A light-receiving calibration member, which is pivotally provided on the light-aligning member around a vertical axis. The light-receiving calibration member has a scale, and the scale is opposite to the light-aligning hole and extends in the horizontal direction, so that the laser beam emitted from the light-aligning hole can be projected onto the scale;

[0012] According to the light-aligning calibration bracket provided by the embodiment of the present invention, the light-aligning member can slide in the horizontal direction, and the light-receiving calibration member can pivot around the vertical axis.

In this way, a light-aligning path with the laser, the light-aligning member, and the light-receiving calibration member in a straight line is realized. The alignment principle is clear and the operation is convenient. By the position where the laser beam is projected on the scale, it can be judged whether the laser beam is perpendicular to the scale, and further, it can be determined whether the longitudinal central axis of the vehicle is perpendicular to the horizontal slide rail. In addition, both the light-aligning member and the light-receiving calibration member can move vertically along with the lifting seat, thereby adjusting the height positions of the light-aligning member and the light-receiving calibration member.

[0106] The optical alignment calibration bracket and vehicle calibration equipment according to the embodiments of the present invention will be described in detail below with reference to the drawings.

[0107] Refer to Figures 1 to 8 As shown, the optical alignment calibration bracket according to the embodiment of the present invention includes a moving frame 10, a lifting seat 20, an optical element 30, a light-receiving calibration element 40 and a horizontal slide rail 50.

[0108] Specifically, the moving frame 10 can be erected and placed on a bearing object such as the ground of the detection site, and can move within the detection site. Preferably, casters can be provided at the bottom of the moving frame 10, thereby facilitating the movement of the moving frame 10 and making the movement of the moving frame 10 more flexible and labor-saving. The lifting seat 20 is movably provided on the moving frame 10 in the vertical direction, that is, the lifting seat 20 can move up and down in the vertical direction on the moving frame 10.

[0109] The light-aligning member 30 is slidably provided on the lifting seat 20 in the horizontal direction. The light-aligning member 30 has a pair of light holes H30 for allowing a laser beam to pass through. The laser beam is emitted by a laser 70 to calibrate the longitudinal central axis of the vehicle, that is, the laser beam coincides with the longitudinal central axis of the vehicle. The light-receiving calibration member 40 is pivotally provided on the light-aligning member 30 about a vertical axis. The light-receiving calibration member 40 has a scale 401. The scale 401 is opposite to the light hole H30 and extends in the horizontal direction so that the laser beam emitted from the light hole H30 can be projected onto the scale 401.

[0110] The horizontal slide rail 50 is provided on the light-receiving calibration member 40 and is parallel to the scale 401. Preferably, the horizontal slide rail 50 is slidably provided on the light-receiving calibration member 40 in the horizontal direction and is parallel to the scale 401. The horizontal slide rail 50 can be used to install a radar calibration plate and a pattern plate. The radar calibration plate is used to calibrate the radar of the vehicle, and the pattern plate is used to calibrate the camera of the vehicle. Thus, with this light-aligning and calibrating bracket, it can assist in calibrating the radar and camera of the vehicle.

[0111] That is to say, the light-aligning member 30 is provided on the lifting seat 20 and can not only move up and down in the vertical direction with the lifting seat 20 but also move horizontally relative to the lifting seat 20. And the light-receiving calibration member 40 is provided on the light-aligning member 30 and can not only move up and down in the vertical direction together with the light-aligning member 30 and the lifting seat 20 but also pivot about the vertical axis relative to the light-aligning member 30. Thus, by the vertical movement of the lifting seat 20, the height positions of the light-aligning member 30 and the light-receiving calibration member 40 in the vertical direction can be adjusted so that the light hole H30 on the light-aligning member 30 and the scale 401 on the light-receiving calibration member 40 are at the same height as the laser beam emitted by the laser 70. By the horizontal movement of the light-aligning member 30, the light hole H30 of the light-aligning member 30 can be aligned with the laser beam so that the laser beam can pass through the light hole H30 and then be projected onto the scale of the light-receiving calibration member 40. By rotating the light-receiving calibration member 40 about the vertical axis, the scale can be deflected relative to the light hole H30, that is, the angle of the scale is adjusted, and further the scale 401 is adjusted to be perpendicular to the laser beam.

[0112] Exemplarily, multiple scale values can be set on the scale 401. One of the scale values is set as the calibration scale 4011, and the remaining scale values are set as the offset reference scales 4012. When the laser beam is projected onto the calibration scale 4011, the scale 401 is perpendicular to the laser beam. When the laser beam is projected onto the offset reference scale 4012, the scale 401 is not perpendicular to the laser beam. For example, the scale value of the calibration scale 4011 is set to 0 at the center of the scale 401, and multiple scale values are sequentially set for the offset reference scales 4012 on both sides of the calibration scale 4011. Thus, during the adjustment process, by rotating the light-receiving calibration member 40 around the vertical axis, the angle of the scale 401 is adjusted. When the laser beam just projects onto the position of the calibration scale 4011, the scale 401 can form a perpendicular state with the laser beam. Since the horizontal slide rail 50 is parallel to the scale 401, when the laser beam projects onto the calibration scale 4011 of the scale 401, the laser beam is perpendicular to the scale 401. At the same time, the laser beam is also perpendicular to the horizontal slide rail 50.

[0113] During the specific adjustment process of the calibration bracket, the laser 70 is placed at the central position in the vehicle's transverse direction. The laser 70 is turned on to emit a laser beam. The alignment calibration bracket is placed in front of or behind the vehicle. First, the height position of the lifting seat 20 can be adjusted so that the alignment hole H30 on the alignment member 30 and the scale 401 on the light-receiving calibration member 40 are at the same height as the laser beam emitted by the laser 70. Then, the alignment member 30 is adjusted to move horizontally so that the laser beam passes through the alignment hole H30 on the alignment member 30 and projects onto the scale 401 on the light-receiving calibration member 40. The light-receiving calibration member 40 can be further adjusted to pivot around the vertical axis so that the laser beam projects onto the position of the calibration scale 4011 on the scale 401. At this time, the scale 401 and the horizontal slide rail 50 are perpendicular to the laser beam. In this way, the adjustment of the horizontal slide rail 50 to be perpendicular to the vehicle's longitudinal central axis can be achieved.

[0114] According to the optical alignment bracket provided by the embodiment of the present invention, the optical alignment member 30 can slide in the horizontal direction, and the light-receiving calibration member 40 can pivot around the vertical axis. After the longitudinal central axis of the vehicle is calibrated by the laser beam, the optical alignment member 30 can be adjusted in the horizontal direction so that the laser beam emitted from the laser 70 can pass through the optical alignment hole H30 of the optical alignment member 30. Moreover, the light-receiving calibration member 40 can be rotated and adjusted around the vertical axis so that the laser beam passing through the optical alignment hole H30 can be projected onto the scale of the light-receiving calibration member 40. In this way, an optical alignment path with the laser 70, the optical alignment member 30, and the light-receiving calibration member 40 in a straight line is achieved. The alignment principle is clear and the operation is convenient. By the position where the laser beam is projected on the scale 401, it can be judged whether the laser beam is perpendicular to the scale 401, and further, it can be determined whether the longitudinal central axis of the vehicle is perpendicular to the horizontal slide rail 50. In addition, both the optical alignment member 30 and the light-receiving calibration member 40 can move vertically along with the lifting seat 20, thereby adjusting the height positions of the optical alignment member 30 and the light-receiving calibration member 40. At the same time, the optical alignment member 30 and the light-receiving calibration member 40 can move in the horizontal direction. In this way, different vehicle models and detection sites can be adapted.

[0115] It should be noted that when the detection site is uneven, the front wheels and rear wheels of the vehicle may not be in the same plane. Similarly, the laser 70, the optical alignment hole H30, and the light-receiving calibration member 40 may also be at different height positions, and the laser beam cannot pass through the optical alignment hole H30. Therefore, by adjusting the height positions of the optical alignment member 30 and the light-receiving calibration member 40, different detection sites can be adapted.

[0116] Refer to Figure 4 and Figures 6 to 8 As shown in the figure, in an embodiment of the present invention, a first locking member 31 is further included. The first locking member 31 is arranged between the optical alignment member 30 and the lifting seat 20 to relatively lock and fix the optical alignment member 30 and the lifting seat 20. That is to say, the first locking member 31 can be used to relatively lock and fix the optical alignment member 30 and the lifting seat 20. In this way, after the optical alignment member 30 moves horizontally to a predetermined position and the laser beam passes through the optical alignment hole H30 on the optical alignment member 30, the optical alignment member 30 and the lifting seat 20 can be locked and fixed by the first locking member 31, so that the optical alignment member 30 is maintained at this predetermined position, preventing the optical alignment member 30 from being displaced by other external forces and ensuring that the laser beam and the optical alignment hole H30 are aligned without displacement and other problems.

[0117] Refer to Figures 4 to 8 As shown in the figure, in an embodiment of the present invention, the optical alignment member 30 includes a sliding plate 301 and an extension portion 302. Among them, the sliding plate 301 is slidably arranged on the lifting seat 20 in the horizontal direction; the extension portion 302 extends downward from one side of the sliding plate 301, and the optical alignment hole H30 is opened on the extension portion 302.

[0118] That is to say, the optical alignment member 30 mainly consists of a sliding plate 301 and an extension portion 302. The sliding plate 301 can slide horizontally on the lifting seat 20, and the extension portion 302 is located on one side of the sliding plate 301 and is integrally formed with the sliding plate 301. Therefore, when the sliding plate 301 slides, the extension portion 302 can slide along with the sliding plate 301, thereby adjusting the position of the optical alignment hole H30 in the horizontal direction.

[0119] In this embodiment, by using the sliding of the sliding plate 301 in the horizontal direction, it can be ensured that the adjustment of the position of the optical alignment hole H30 in the horizontal direction is reliable and stable. The extension portion 302 extends downward, and the optical alignment hole H30 is provided on the extension portion 302. In this way, the optical alignment hole H30 can be made to be far away from the sliding plate 301 and the lifting seat 20, which is convenient for the optical alignment hole H30 to be aligned with the laser beam.

[0120] Exemplarily, the first locking member 31 includes a first handle 311 and a first screw portion 312 connected to the first handle 311. There is a side blocking portion 303 between the sliding portion and the extension portion 302. The side blocking portion 303 is located on one side of the sliding plate 301, and a strip-shaped hole extending in the horizontal direction is provided on the side blocking portion 303. A threaded hole is provided on the sliding plate 301. The first handle 311 is located outside the side blocking portion 303, and the first screw portion 312 passes through the strip-shaped hole and is threadedly connected to the threaded hole. In this way, by operating and rotating the first handle 311, the first handle 311 can lock and fix the side blocking portion 303 on the sliding plate 301. In this way, the sliding plate 301 can be locked and fixed to the lifting seat 20, and the operation is convenient and the locking is reliable.

[0121] Refer to Figures 4 to 6 As shown, in an embodiment of the present invention, the lifting seat 20 includes a horizontal plate 201 and a vertical plate 202. Among them, the optical alignment member 30 is slidably provided on the horizontal plate 201 in the horizontal direction; the vertical plate 202 is connected to the horizontal plate 201 to form an L shape, and the vertical plate 202 is movably provided on the moving frame 10.

[0122] That is to say, the lifting seat 20 is composed of a horizontal plate 201 and a vertical plate 202 connected to form an L-shaped structure. The sliding plate 301 of the optical alignment member 30 can be installed on the horizontal plate 201 through a sliding component to realize sliding in the horizontal direction relative to the lifting seat 20, and the vertical plate 202 is movably provided on the moving frame 10 along the vertical direction. In this way, the lifting seat 20 can be moved vertically, and its structure is simple and the installation is convenient.

[0123] Refer to Figures 1 to 5As shown, in an embodiment of the present invention, the light-receiving calibration member 40 includes a pivot seat 402 and a connecting member 403. Among them, the pivot seat 402 is pivotally arranged on the light-aligning member 30 around the vertical axis; the connecting member 403 is connected between the pivot seat 402 and the scale 401.

[0124] That is to say, the light-receiving calibration member 40 is mainly composed of a pivot seat 402, a connecting member 403 and a scale 401. The scale 401 is connected to the pivot seat 402 through the connecting member 403, and the pivot seat 402 is pivotally arranged on the light-aligning member 30 around the vertical axis. Thus, when the pivot seat 402 pivots relative to the light-aligning member 30, the scale 401 also pivots with the pivot seat 402, thereby adjusting the angle of the scale 401.

[0125] In this embodiment, pivotally connecting the pivot seat 402 to the light-aligning member 30 facilitates the pivoting of the light-receiving calibration member 40, and the scale 401 is connected to the pivot seat 402 through the connecting member 403, so that the scale 401 can be opposite to the extension portion 302 of the light-aligning member 30, which is convenient for receiving the laser beam projected by the light head.

[0126] Exemplarily, a clearance hole 2011 is provided on the horizontal plate 201. The connecting member 403 includes a horizontal portion 4031 and a vertical portion 4032. One end of the horizontal portion 4031 is connected to the pivot seat 402, one end of the vertical portion 4032 is connected to the horizontal portion 4031, and the other end of the vertical portion 4032 passes downward through the clearance hole 2011 and is connected to the scale 401.

[0127] That is to say, the horizontal portion 4031 and the vertical portion 4032 are connected to form an L-shaped connecting member 403. The scale 401 is connected to the vertical portion 4032, and the vertical portion 4032 is arranged in the clearance hole 2011. Thus, the L-shaped connecting member 403 facilitates the connection between the scale 401 and the pivot seat 402.

[0128] Optionally, a damper 32 that can pivot around the vertical axis is provided on the light-aligning member 30. The pivot seat 402 is sleeved on the damper 32 and is circumferentially fixed relative to the damper 32. Figure 6 In the example, a round table 304 protruding upward is provided on the sliding plate 301. The damper 32 is pivotally arranged in the round table 304. The upper end of the damper 32 is a polygonal socket portion. The pivot seat 402 has a blind hole, and the blind hole is pivotally sleeved outside the round table 304. A polygonal groove H402 is provided on the top wall of the blind hole. The socket portion of the damper 32 is sleeved with the groove H402 of the blind hole, thereby realizing the circumferential relative fixation between the pivot seat 402 and the damper 32.

[0129] In this embodiment, the light-receiving calibration member 40 is pivotally provided on the damper 32. In this way, the light-receiving calibration member 40 can have a relatively appropriate damping during rotation, ensuring more accurate and reliable adjustment when rotating the light-receiving calibration member 40. In addition, the damping of the damper 32 can be adjusted, so that the light-receiving calibration member 40 has an appropriate damping.

[0130] Referring to Figure 4 and Figure 5 As shown, in an embodiment of the present invention, two guiding blocks 41 are provided on the light-receiving calibration member 40, and sliding grooves are provided on the two guiding blocks 41, and the horizontal sliding rail 50 is slidably disposed in the sliding grooves of the two guiding blocks 41. That is, the horizontal sliding rail 50 is slidably assembled in the sliding grooves of the two guiding blocks 41, and the guiding blocks 41 are installed on the light-receiving calibration member 40. In Figure 4 and Figure 5 the example, the two guiding blocks 41 are respectively installed at both ends of the pivot seat 402 in the horizontal direction. In this way, the horizontal sliding rail 50 is slidably engaged with the guiding blocks 41, and reliable and smooth sliding of the horizontal sliding rail 50 in the horizontal direction can be achieved.

[0131] Advantageously, one of the two guiding blocks 41 is slidably connected to the light-receiving calibration member 40 through a dovetail structure, and one of the two guiding blocks 41 is fixedly connected to the light-receiving calibration member 40 through a fastener. In Figure 4 and Figure 5 the example, a dovetail rail 42 extending in the vertical direction is provided on one guiding block 41, a dovetail groove 4021 extending in the vertical direction is provided at one end of the pivot seat 402, a threaded hole extending in the vertical direction is provided on the other guiding block 41, and a through hole is provided at the other end of the pivot seat 402. During assembly, the dovetail rail 42 on one guiding block 41 can be first inserted into the dovetail groove 4021 at one end of the pivot seat 402, and then a fastener such as a screw is used to pass through the through hole at the other end of the pivot seat 402 and then connected to the threaded hole on the other guiding block 41. In this way, the horizontal sliding rail 50 can be installed on the pivot seat 402, and the installation is convenient and the disassembly is simple.

[0132] Referring to Figures 4 to 5 As shown, in some embodiments of the present invention, a driving device 60 is further included. The driving device 60 is provided on the moving frame 10 and is connected to the lifting seat 20 for driving the lifting seat 20 to move vertically. In this way, the driving device 60 can be used to drive the lifting seat 20 to move vertically, which is convenient for adjusting the height position of the lifting seat 20.

[0133] In an example of the present invention, the driving device 60 includes a lead screw 601, a lead screw nut 602, and a driving member 603. Among them, the lead screw 601 is pivotally arranged on the moving frame 10 around its own axis and extends vertically; the lead screw nut 602 is threadedly sleeved on the lead screw 601 and fixedly connected to the lifting seat 20; the driving member 603 is connected to the lead screw 601 for driving the lead screw 601 to rotate.

[0134] When the driving member 603 drives the lead screw 601 to rotate, the lead screw nut 602 can move up and down vertically on the lead screw 601. Since the lifting seat 20 is fixed on the lead screw nut 602, the lead screw nut 602 can drive the lifting seat 20 to move up and down vertically. In this way, the driving of the lifting seat 20 can be realized, and its structure is simple. Moreover, by using the cooperation of the lead screw 601 and the lead screw nut 602, the height adjustment accuracy of the lifting seat 20 is high.

[0135] Optionally, the driving member 603 includes a crank 6031 and a gear set 6032. The crank 6031 is pivotally arranged on the moving frame 10. The gear set 6032 includes at least a driving gear and a driven gear. The driving gear is arranged on the crank 6031 and is driven to rotate by the crank 6031. The driven gear is arranged on the lead screw 601 and meshes with the driving gear. In specific use, the crank 6031 can be operated to drive the driving gear to rotate. The driving gear further drives the driven gear on the lead screw to rotate, and the driven gear can drive the lead screw 601 to rotate. In this way, by operating the crank 6031, it is convenient to adjust the height of the lifting seat 20 as needed, and the operation is simple and convenient.

[0136] Exemplarily, the crank 6031 is pivotally arranged on the side surface of the moving frame 10, and the driving gear and the driven gear are bevel gears. In this way, it is convenient for the driven gear on the lead screw 601 to mesh with the driving gear on the crank 6031. Moreover, since the crank 6031 is arranged on the side surface of the moving frame 10, it is convenient for use and operation.

[0137] Refer to Figure 5 As shown, in an embodiment of the present invention, the driving device 60 further includes a second locking member 604. The second locking member 604 is arranged between the crank 6031 and the moving frame 10 for locking and fixing the crank 6031 and the moving frame 10. In this way, after the crank 6031 is operated to adjust the lifting seat 20 to the required height position, the crank 6031 and the moving seat can be relatively locked by the second locking member 604 to prevent problems such as the lifting seat 20 being displaced due to rotation caused by other external forces after the adjustment of the lifting seat 20 is completed, and to ensure that the lifting seat 20 can be reliably maintained at the required position.

[0138] Refer to Figures 6 to 8As shown, in an embodiment of the present invention, an adjustable limiting member 33 is further included. The adjustable limiting member 33 is provided on the light-aligning member 30 for limiting the light-receiving calibration member 40 after the light-receiving calibration member 40 is rotated and adjusted to a predetermined position.

[0139] That is to say, when the light-receiving calibration member 40 is rotated and adjusted to the required predetermined position, that is, the position where the scale 401 is perpendicular to the laser beam. At this time, the adjustable limiting member 33 can be used to stop the light-receiving calibration member 40, limit the rotation of the light-receiving calibration member 40, and then limit the light-receiving calibration member 40 at this position, and remember the position where the scale 401 is perpendicular to the laser beam.

[0140] Exemplarily, the adjustable limiting member 33 includes a screw 331 and a stop member 333. Among them, the screw 331 and the stop member 333, the screw 331 is provided on the light-aligning member 30 and extends in the horizontal direction; the stop member 333 is provided on the light-receiving calibration member 40, and the stop member 333 has a stop inclined surface S33, and the stop inclined surface S33 abuts against the end of the screw 331. In this way, by rotating the screw 331, the screw 331 can move in the horizontal direction, and the end of the screw 331 can contact the stop inclined surface S33, so as to play a role of stopping and limiting the light-receiving calibration member 40, and achieve the effect of remembering the position of the scale 401. In addition, the screw 331 can be adjusted, which is convenient for stopping and limiting the light-receiving calibration member 40 at different positions. Its operation is convenient and the stop and limit are reliable.

[0141] Refer to Figure 9 As shown, the vehicle calibration device according to an embodiment of the present invention includes a laser 70 and the light-aligning calibration bracket as described above. The light-aligning calibration bracket is disposed opposite to the laser 70 and is used to receive the laser beam emitted by the laser 70. By adjusting the light-receiving calibration member, the horizontal slide rail is made perpendicular to the laser beam.

[0142] It can be understood that during the calibration process, the laser 70 is generally disposed at the central position in the vehicle transverse direction. In this way, after the laser beam passes through the light-aligning hole H30 on the light-aligning member 30, it is projected onto the scale 401 on the light-receiving calibration member 40. In this way, the light-aligning path of the three points of the laser 70, the light-aligning member 30, and the light-receiving calibration member 40 in a straight line can be realized, and the light-aligning calibration bracket is made perpendicular to the laser beam.

[0143] According to the vehicle calibration device provided by an embodiment of the present invention, having the above-mentioned optical alignment bracket, the optical element 30 can slide in the horizontal direction, and the light-receiving calibration element 40 can pivot around a vertical axis. After calibrating the longitudinal central axis of the vehicle with a laser beam, the optical element 30 can be adjusted in the horizontal direction so that the laser beam can pass through the light hole H30 of the optical element 30. Moreover, the light-receiving calibration element 40 can be rotated and adjusted around the vertical axis so that the laser beam passing through the light hole H30 can be projected onto the scale of the light-receiving calibration element 40. In this way, an optical path with the laser 70, the optical element 30, and the light-receiving calibration element 40 in a straight line is achieved. The alignment principle is clear and the operation is convenient. By the position where the laser beam is projected on the scale 401, it can be determined whether the laser beam is perpendicular to the scale 401, and further, it can be determined whether the longitudinal central axis of the vehicle is perpendicular to the horizontal slide rail 50. In addition, both the optical element 30 and the light-receiving calibration element 40 can move vertically along with the lifting seat 20, thereby adjusting the height positions of the optical element 30 and the light-receiving calibration element 40. At the same time, the optical element 30 and the light-receiving calibration element 40 can move in the horizontal direction. In this way, different vehicle models and detection sites can be adapted.
