Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0042] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0043] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0044] The following is combined with Figures 1 to 9 The laser instrument 100, calibration equipment 200 and calibration system provided in the embodiments of this utility model are described in detail.

[0045] Please see Figures 1 to 3 , Figure 1 This is a three-dimensional structural diagram of the laser instrument 100. Figure 2 This is a schematic diagram of the three-dimensional structure of the laser instrument 100 after removing the housing 10. Figure 3 This is a schematic diagram of the exploded structure of the laser instrument 100 after removing the housing 10.

[0046] This utility model provides a laser instrument 100, including a housing 10, a base 20, a rotating bracket 30, a laser instrument 40, and a drive module 50. The base 20 is installed in the housing 10, the rotating bracket 30 is rotatably installed on the base 20, the laser instrument 40 is fixedly installed on the rotating bracket 30, and the drive module 50 is connected to the rotating bracket 30 for transmission. The drive module 50 can drive the rotating bracket 30 and the laser instrument 40 to rotate, so as to adjust the yaw angle of the laser instrument 40.

[0047] The housing 10 can be regular or irregular in shape. For example, the housing 10 can be roughly rectangular in shape. The interior of the housing 10 is hollow and forms a mounting cavity. The base 20, the rotating bracket 30, the laser instrument 40, and the drive module 50 are all disposed in the mounting cavity.

[0048] The base 20 is fixedly installed in the housing 10. Optionally, the base 20 can be fixedly installed in the housing 10 by means of screwing, snap-fitting, etc. The base 20 can be in the form of a plate-like structure to form an installation platform and install the rotating bracket 30 on it. When the rotating bracket 30 is installed on the base 20, the base 20 can provide stable support for the installation of the rotating bracket 30, ensuring the working stability of the laser instrument 100 on the rotating bracket 30.

[0049] The rotating bracket 30 is rotatably mounted on the base 20. The rotating bracket 30 is used to support the laser instrument 40, so that the laser instrument 40 can rotate together with the rotating bracket 30, thereby realizing the adjustment of the rotation angle of the laser instrument 40.

[0050] The laser device 40 is fixedly mounted on the rotating bracket 30. The laser device 40 can be mounted on the side of the rotating bracket 30 opposite to the base 20. Optionally, the laser device 40 can be fixed to the rotating bracket 30 by screws, clips, or other methods. The laser device 40 is used to project laser lines, which can assist users in quickly and accurately locating and calibrating various objects. For example, the laser device 40 can be a two-line laser device. During the calibration of the AroundView Monitor (AVM) system, the two-line laser device can project two mutually perpendicular laser lines to the ground, thereby assisting in the placement of the calibration pattern (AVM pattern).

[0051] The drive module 50 is installed in the housing 10 and is connected to the rotating bracket 30 for transmission. In this way, the drive module 50 can drive the rotating bracket 30 and the laser device 40 to rotate together, thereby adjusting the yaw angle of the laser device 40. It can be understood that the yaw angle of the laser device 40 refers to the angle between the projection of the laser device 40 on the horizontal plane and the earth axis, that is, the rotation angle of the laser device 40 on the horizontal plane.

[0052] In this embodiment, by setting a rotatable rotating bracket 30 on the base 20 and a drive module 50 that can drive the rotating bracket 30 to rotate, when it is necessary to adjust the yaw angle of the laser instrument 40, it is only necessary to start the drive module 50, so that the drive module 50 drives the rotating bracket 30 and the laser instrument 40 to rotate, thereby realizing the precise automatic adjustment of the yaw angle of the laser instrument 40, ensuring adjustment efficiency and accuracy, and avoiding manual adjustment errors.

[0053] In some embodiments, the drive module 50 and the rotating bracket 30 are disposed on the same side of the base 20. The drive module 50 includes a drive member 51 and a linkage assembly 52. ​​One end of the linkage assembly 52 is connected to the output shaft of the drive member 51, and the other end of the linkage assembly 52 is connected to the rotating bracket 30.

[0054] like Figure 3 As shown, both the drive module 50 and the rotating bracket 30 are located above the base 20, which avoids the drive module 50 occupying space in the axial direction of the rotating bracket 30 and helps to improve the overall structural compactness.

[0055] The drive unit 51 is used to provide the mechanical power required for the rotation of the rotating bracket 30. Optionally, the drive unit 51 can be a stepper motor, servo motor, etc. These motors can provide precise speed control and position control to ensure the angle adjustment accuracy of the laser instrument 40.

[0056] The linkage assembly 52 is disposed between the drive member 51 and the rotating bracket 30. The two ends of the linkage assembly 52 are connected to the drive member 51 and the rotating bracket 30 respectively. Through the linkage assembly 52, the power of the drive member 51 can be transmitted to the rotating bracket 30, thereby driving the rotating bracket 30 and the laser device 40 to rotate.

[0057] It is understood that in other embodiments, the driving component 51 may also be a driving cylinder, and the linear motion of the driving cylinder can be converted into the rotational motion of the rotating bracket 30 through the connecting rod assembly 52, thereby realizing the rotation of the rotating bracket 30 and the laser device 40.

[0058] Please see Figures 4 to 6 , Figure 4 This is an exploded structural diagram of the rotating bracket 30, the driving component 51, the connecting rod assembly 52, and the mounting bracket 60. Figure 5 This is a three-dimensional structural diagram of the rotating bracket 30. Figure 6 This is a three-dimensional structural diagram of the mounting bracket 60.

[0059] In some embodiments, the linkage assembly 52 includes a connecting rod 520 and a connecting shaft 521. One end of the connecting rod 520 is connected to the output shaft of the drive member 51, and the other end of the connecting rod 520 is connected to the connecting shaft 521. The rotating bracket 30 is provided with an adjustment hole 320, and the connecting shaft 521 is inserted into the adjustment hole 320 and slides in cooperation with the adjustment hole 320.

[0060] like Figure 4 As shown, the connecting rod 520 has a generally rod-shaped or strip-shaped structure. One end of the connecting rod 520 is connected to the output shaft of the drive component 51, and the other end of the connecting rod 520 can extend towards the rotating bracket 30 and reach the upper position of the rotating bracket 30. The connecting shaft 521 is perpendicular to the connecting rod 520. One end of the connecting shaft 521 is fixedly connected to the other end of the connecting rod 520, and the other end of the connecting shaft 521 extends towards the rotating bracket 30 to facilitate insertion into the adjustment hole 320 on the rotating bracket 30.

[0061] The adjustment hole 320 can be located at the edge of the upper surface of the rotating bracket 30. Optionally, the adjustment hole 320 can be a strip-shaped hole. When it is necessary to adjust the yaw angle of the laser instrument 40, the driving component 51 drives the connecting rod 520 and the connecting shaft 521 to rotate, so that the connecting shaft 521 pushes the rotating bracket 30 and the laser instrument 40 to rotate, thereby adjusting the yaw angle of the laser instrument 40. It can be understood that during the process of the connecting shaft 521 driving the rotating bracket 30 to rotate relative to the base 20, the connecting shaft 521 can slide relative to the adjustment hole 320 to avoid jamming of the connecting rod assembly 52 and the rotating bracket 30 during rotation.

[0062] In some embodiments, such as Figure 5 As shown, the rotating bracket 30 includes a rotating body 31 and a connecting protrusion 32 protruding from the side of the rotating body 31. The rotating body 31 is rotatably engaged with the base 20. The laser device 40 is mounted on the rotating body 31. An adjustment hole 320 is provided on the connecting protrusion 32.

[0063] like Figure 5 As shown, the rotating support 30 includes a rotating body 31 and a connecting protrusion 32. Optionally, the rotating body 31 and the connecting protrusion 32 are integrally formed to ensure structural strength. The rotating body 31 is rotatably engaged with the base 20, allowing the rotating support 30 to rotate relative to the base 20. The laser device 40 is fixedly mounted on the rotating body 31.

[0064] The connecting protrusion 32 protrudes from the outer periphery of the rotating body 31 and extends toward the driving member 51. The connecting protrusion 32 shortens the transmission distance between the rotating bracket 30 and the driving member 51, which helps to improve transmission efficiency. The adjusting hole 320 is formed on the connecting protrusion 32, and the end of the connecting rod 520 away from the driving member 51 extends to the upper position of the connecting protrusion 32, so that the connecting shaft 521 can be inserted into the adjusting hole 320 on the connecting protrusion 32.

[0065] In some embodiments, the laser instrument 100 further includes a mounting bracket 60, which is perpendicular to the base 20 and is located on the same side of the base 20 as the rotating bracket 30. The mounting bracket 60 has a mounting groove 61 and a receiving groove 62. The mounting groove 61 is located on the side of the receiving groove 62 away from the base 20. A connecting hole 610 is provided on the groove wall of the mounting groove 61. The mounting groove 61 and the receiving groove 62 are connected through the connecting hole 610. The driving member 51 is installed in the mounting groove 61. The connecting rod 520 is at least partially disposed in the receiving groove 62. The output shaft of the driving member 51 extends into the receiving groove 62 through the connecting hole 610 and is connected to the connecting rod 520.

[0066] like Figure 4 and Figure 6 As shown, the laser instrument 100 includes a mounting bracket 60, which has a generally plate-like structure. The mounting bracket 60 can be mounted vertically or substantially vertically on the base 20. Optionally, the mounting bracket 60 is mounted vertically at the edge of the base 20 and is located on the same side of the base 20 as the rotating bracket 30.

[0067] The mounting bracket 60 has a mounting groove 61 and a receiving groove 62. The mounting groove 61 is used to mount the drive component 51, and the receiving groove 62 is used to accommodate the connecting rod 520, which helps to improve the overall structural compactness. The mounting groove 61 is located above the receiving groove 62. The mounting groove 61 and the receiving groove 62 are connected by a connecting hole 610. The output shaft of the drive component 51 can pass through the connecting hole 610 and connect to the connecting rod 520 in the receiving groove 62, thereby realizing the transmission connection between the drive component 51 and the connecting rod 520.

[0068] Optionally, the connecting protrusion 32 may extend toward the receiving groove 62 to facilitate the insertion of the connecting shaft 521 into the adjustment hole 320 on the connecting protrusion 32.

[0069] Please refer to the following: Figure 3 In some embodiments, the laser instrument 100 further includes a circuit board 70, which is disposed on the side of the mounting bracket 60 facing the laser instrument, and the laser instrument and the drive unit 51 are electrically connected to the circuit board 70 respectively.

[0070] The circuit board 70 can be a printed circuit board, which can be fixed to the mounting bracket 60 by screwing, snapping, or gluing. The laser instrument is electrically connected to the circuit board 70, through which the laser emission and laser power can be controlled. The driver 51 is electrically connected to the circuit board 70, and the circuit board 70 can precisely control the start and stop of the driver 51, thereby achieving precise control of the laser instrument's yaw angle.

[0071] Since the circuit board 70 is located between the laser instrument and the mounting bracket 60, the circuit board 70 is close to the laser instrument and the driving component 51, which facilitates the electrical connection between the circuit board 70 and the laser instrument and the driving component 51.

[0072] Please refer to the following: Figure 3 and Figure 7 In some embodiments, the base 20 is provided with a first rotating part 21 (see...) Figure 3 The rotating bracket 30 is provided with a second rotating part 33 (see Figure 7 The first rotating part 21 and the second rotating part 33 are rotatably engaged; one of the first rotating part 21 and the second rotating part 33 is a rotating shaft, and the other is a rotating shaft hole.

[0073] The base 20 has a first rotating part 21 on the side facing the rotating body 31, and the rotating body 31 has a second rotating part 33 on the side facing the base 20. The rotating bracket 30 and the base 20 are rotated together by the rotational cooperation of the first rotating part 21 and the second rotating part 33.

[0074] One of the first rotating part 21 and the second rotating part 33 is a rotating shaft, and the other is a rotating shaft hole. For example, in Figure 3 and Figure 7 In this configuration, the first rotating part 21 can be a pivot hole, and the second rotating part 33 can be a pivot. That is, the base 20 has a pivot hole, and the rotating body 31 has a pivot on the side facing the base 20. By inserting the pivot on the rotating body 31 into the pivot hole on the base 20, the rotational connection between the two can be achieved.

[0075] It is understood that in other embodiments, the first rotating part 21 may be a rotating shaft and the second rotating part 33 may be a rotating shaft hole. That is, the base 20 is provided with a rotating shaft on the side facing the rotating body 31, and the rotating body 31 is provided with a rotating shaft hole, which can also realize the rotational connection between the base 20 and the rotating bracket 30.

[0076] Please see Figure 8 , Figure 8 This is an exploded structural diagram of the rotating support 30 and the laser instrument 40.

[0077] In some embodiments, a limiting groove 34 is provided on the side of the rotating bracket 30 facing the laser, and the end of the laser facing the rotating bracket 30 is inserted into the limiting groove 34.

[0078] like Figure 8 As shown, the limiting groove 34 is formed on the side of the rotating body 31 facing the laser. The limiting groove 34 can be an annular groove, but is not limited to this. For example, the limiting groove 34 can also be a square groove or a polygonal groove. The bottom end of the laser is inserted into the limiting groove 34. The limiting groove 34 restricts the movement of the laser in the horizontal direction (the radial direction of the rotating bracket 30), ensuring the installation position accuracy of the laser 40 on the rotating bracket 30.

[0079] In some embodiments, such as Figure 8 As shown, the rotating bracket 30 has a first connection hole 35 on the side facing the laser, and the laser has a second connection hole 41 on the side facing the rotating bracket 30. The first connection hole 35 and the second connection hole 41 are fixedly connected by fasteners.

[0080] Specifically, the fasteners can be screws, bolts, or other fasteners. The first connecting hole 35 and the second connecting hole 41 can be threaded holes. When the laser instrument is inserted into the limiting groove 34, the positions of the first connecting hole 35 and the second connecting hole 41 correspond. Then, the fasteners are screwed into the second connecting hole 41 and the second connecting hole 41 in sequence, which can realize the threaded connection between the rotating bracket 30 and the laser instrument, ensuring the assembly stability of the laser instrument on the rotating bracket 30 and avoiding measurement errors caused by the laser instrument being loose or shaking.

Specifically, the calibration device 200 can be used to calibrate and standardize an advanced driver assistance system (ADAS) for a vehicle.

[0082] The calibration equipment includes a crossbeam 201, a base 202, and a column 203. The laser instrument 100 is mounted on the crossbeam 201, the column 203 is vertically mounted on the base 202, and the crossbeam 201 is mounted on the column 203. Optionally, there are two laser instruments 100, which are respectively mounted at opposite ends of the crossbeam 201.

[0083] Since the calibration equipment includes the laser instrument 100 in any of the above embodiments, it also has the beneficial effects of any of the above embodiments. For specific beneficial effects, please refer to the above text, which will not be repeated here.

[0084] The base 202 is typically made of high-strength materials, such as cast iron or steel, to provide stable and reliable support for the entire calibration equipment 200. Optionally, the bottom of the base 202 is equipped with casters to facilitate the movement of the calibration equipment 200.

[0085] The column 203 can be rod-shaped or column-shaped. The column 203 can be made of high-strength aluminum alloy or steel to ensure sufficient strength and rigidity. The bottom end of the column 203 is vertically connected to the base 202. Optionally, the bottom end of the column 203 can be detachably installed on the base 202 by means of snap-fit, screw connection or other methods to facilitate the assembly and disassembly of the column 203.

[0086] The crossbeam 201 can be made of a lightweight yet high-strength material, such as aluminum alloy profile, to reduce its weight while ensuring sufficient rigidity. The crossbeam 201 can be slidably mounted on the column 203 to facilitate adjustment of the installation height of the crossbeam 201 on the column 203.

[0087] In some embodiments, such as Figure 1 and Figure 9 As shown, a connecting plate 80 is provided on the housing 10 of the laser instrument 100, and the laser instrument 100 is fixedly connected to the crossbeam 201 of the calibration device 200 through the connecting plate 80.

[0088] Based on the same inventive concept, this utility model embodiment also provides a calibration system, which includes the calibration device 200 and a diagnostic instrument as described in the above embodiment, and the diagnostic instrument is communicatively connected to the calibration device 200.
