[0001] This application claims priority to Chinese Patent Application No. 2025101169123, filed on January 24, 2025, entitled “Crossbeam Module, Calibration Equipment and Calibration System”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of vehicle calibration technology, and in particular to a crossbeam module, calibration equipment and calibration system. Background Technology

[0003] With the development of the automotive industry and the advancement of technology, people have higher requirements for the safety and comfort of driving. Autonomous driving, as an important direction in current automotive technology development, has seen its early stage—Advanced Driver Assistance Systems (ADAS)—become one of the key technologies for improving vehicle safety. Due to the increasing emphasis on vehicle safety, more and more vehicles are equipped with ADAS systems. However, when an ADAS system malfunctions or malfunctions, it needs to be recalibrated to ensure its normal and safe use.

[0004] In related technologies, ADAS calibration equipment is usually used to calibrate and standardize ADAS systems. The ADAS calibration equipment includes a crossbeam and a mounting plate that slides on the crossbeam. The mounting plate is used to mount calibration elements, which can be used to calibrate or standardize the sensors on the vehicle.

[0005] However, during the calibration process, staff usually need to manually adjust the position of the mounting plate on the crossbeam. The manual adjustment method has drawbacks such as long adjustment time and large adjustment error, which affects the calibration efficiency and calibration accuracy. Summary of the Invention

[0006] The embodiments of this application aim to provide a crossbeam module, calibration equipment and calibration system to solve the technical problems in the prior art where the hanging plate on the crossbeam needs to be manually adjusted, which has the problems of long adjustment time and large adjustment error.

[0007] To solve its technical problem, this application adopts the following technical solution: providing a beam module, including:

[0008] A crossbeam, wherein a rack is provided along its length;

[0009] A sliding member, which is slidably mounted on the crossbeam;

[0010] A drive mechanism is mounted on the sliding member. The drive mechanism includes a drive member and an output gear that is pulsatorically connected to the drive member. The output gear meshes with the rack.

[0011] The drive unit can drive the output gear to mesh with the rack, so that the slider can slide along the crossbeam.

[0012] In some embodiments, the driving mechanism further includes a driving gear and a reduction gear set. The driving gear is disposed on the output shaft of the driving member, and the reduction gear set is disposed between the driving gear and the output gear. The driving member drives the driving gear to rotate, and sequentially drives the reduction gear set and the output gear to rotate.

[0013] In some embodiments, the reduction gear set includes a first gear and a second gear arranged coaxially, a third gear and a fourth gear arranged coaxially, and a fifth gear arranged coaxially with the output gear. The first gear meshes with the drive gear, the second gear meshes with the third gear, and the fourth gear meshes with the fifth gear.

[0014] In some embodiments, the drive mechanism further includes an encoder and an encoder gear connected to each other, the encoder gear meshing with the reduction gear set.

[0015] In some embodiments, the encoder gear meshes with the fifth gear.

[0016] In some embodiments, the sliding member includes a sliding plate and a back plate, the back plate covering the side of the sliding plate facing the crossbeam, the sliding plate and the back plate forming a receiving cavity, and the drive gear and the reduction gear set are both installed in the receiving cavity.

[0017] In some embodiments, the drive mechanism further includes a locking member, which is rotatably mounted in the receiving cavity and has an engaging portion.

[0018] When the crossbeam is in the unfolded state, the meshing part is separated from the reduction gear set and the drive gear;

[0019] When the crossbeam is in a folded state, the locking member rotates relative to the sliding member under its own weight, so that the meshing part engages with the reduction gear set or the drive gear.

[0020] In some embodiments, when the crossbeam is in a folded state, the meshing portion can engage with the drive gear.

[0021] In some embodiments, the slider has an unlocking hole for an unlocking tool to be inserted into the receiving cavity, and the unlocking hole corresponds to the position of the locking member.

[0022] In some embodiments, the crossbeam has a connected mounting groove and a receiving groove on the side facing the slider, the rack is mounted in the mounting groove, and the output gear is located in the receiving groove and meshes with the rack.

[0023] In some embodiments, a guide rail is provided at the bottom of the crossbeam, and a slider is connected to the sliding member, the slider being slidably mounted on the guide rail.

[0024] To address its technical problems, this application also employs the following technical solution: providing a calibration device, the calibration device including the beam module as described in any of the above embodiments; and

[0025] Base;

[0026] The column is vertically mounted on the base, and the crossbeam module is installed on the column.

[0027] To address its technical problems, this application also employs the following technical solution: providing a calibration system, the calibration system including the calibration equipment described in the above embodiments; and

[0028] A diagnostic instrument, which is communicatively connected to the calibration device.

[0029] Compared with the prior art, the embodiments of this application provide a crossbeam module, calibration equipment and calibration system. By driving the output gear to rotate relative to the rack through the driving component, the rotational motion of the gear is converted into linear motion along the rack direction, thereby driving the sliding component to move along the length direction of the crossbeam. This can realize precise and automated adjustment of the position of the calibration element on the sliding component, ensuring adjustment efficiency and accuracy, and reducing manual adjustment errors.

Detailed Implementation

[0044] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0045] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application 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.

[0046] 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 this application. 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.

[0047] The beam module 30, calibration equipment 100, and calibration system provided in the embodiments of this application will be described in detail below with reference to Figures 1 to 13.

[0048] Please refer to Figures 1 and 2. Figure 1 is a three-dimensional structural diagram of the calibration device 100 in the working state (the crossbeam is in the unfolded state), and Figure 2 is a three-dimensional structural diagram of the calibration device 100 in the storage state (the crossbeam is in the folded state).

[0049] This application provides a calibration device 100, which can be used to calibrate and standardize ADAS systems. The calibration device 100 includes a base 10, a column 20, and a crossbeam module 30. The column 20 is vertically mounted on the base 10, and the crossbeam module 30 is mounted on the column 20.

[0050] The base 10 is typically made of high-strength materials, such as cast iron or steel, to provide stable and reliable support for the entire calibration equipment 100. Optionally, the base 10 is equipped with casters at the bottom to facilitate movement of the calibration equipment 100.

[0051] The column 20 can be rod-shaped or column-shaped. The column 20 can be made of high-strength aluminum alloy or steel to ensure sufficient strength and rigidity. The bottom end of the column 20 is vertically connected to the base 10. Optionally, the bottom end of the column 20 can be detachably installed on the base 10 by means of snap-fit, screw connection or other methods to facilitate the assembly and disassembly of the column 20.

[0052] The crossbeam module 30 can be made of a lightweight and high-strength material, such as aluminum alloy profile, to reduce its own weight while ensuring sufficient rigidity. The crossbeam module 30 can be slidably installed on the column 20 to facilitate adjustment of the installation height of the crossbeam module 30 on the column 20.

[0053] Optionally, the crossbeam module 30 has an unfolded state and a folded state. When the crossbeam module 30 is unfolded in a straight line, the length of the entire crossbeam module 30 can be maximized, facilitating calibration operations. When the calibration equipment 100 needs to be stored, the crossbeam module 30 can be folded to reduce the overall volume of the calibration equipment 100 and improve its portability and flexibility.

[0054] Please refer to Figures 3 to 5. Figure 3 is a three-dimensional structural diagram of the crossbeam module 30. Figure 4 is a three-dimensional structural diagram of the rack 34, drive mechanism 33 and sliding member 32. Figure 5 is a schematic diagram of the transmission relationship between drive member 330, reduction gear set 333, output gear 331, drive gear 332 and rack 34.

[0055] In some embodiments, the crossbeam module 30 includes a crossbeam 31, a slider 32, and a drive mechanism 33. The crossbeam 31 is provided with a rack 34 along its length. The slider 32 is slidably mounted on the crossbeam 31. The drive mechanism 33 is mounted on the slider 32. The drive mechanism 33 includes a drive member 330 and an output gear 331 that is pulsally connected to the drive member 330. The output gear 331 meshes with the rack 34. The drive member 330 can drive the output gear 331 to mesh with the rack 34, so that the slider 32 can slide along the crossbeam 31.

[0056] The crossbeam 31 can be a hollow tubular structure. The rack 34 is arranged along the length of the crossbeam 31 and is located on the side of the crossbeam 31 near the sliding member 32, so as to mesh with the output gear 331. Optionally, the rack 34 can be fixedly installed on the crossbeam 31 by means of screwing, snap-fitting, bonding, etc.

[0057] The sliding member 32 is slidably mounted on the crossbeam 31. The sliding member 32 is used to mount calibration elements such as calibration targets, rearview mirrors, and lasers to calibrate the vehicle's driver assistance system. The calibration targets, rearview mirrors, lasers, and other calibration elements can be mounted on the side of the sliding member 32 facing away from the crossbeam 31.

[0058] The drive mechanism 33 is mounted on the sliding member 32. The drive mechanism 33 includes a drive member 330 and an output gear 331. The drive member 330 is fixedly mounted on the side of the sliding member 32 near the crossbeam 31. The output gear 331 is in transmission cooperation with the drive member 330 and meshes with the rack 34. The drive member 330 is used to provide power for the rotation of the output gear 331. The drive member 330 drives the output gear 331 to rotate relative to the rack 34, converting the rotational motion of the gear into linear motion along the direction of the rack 34, thereby driving the sliding member 32 to move along the length direction of the crossbeam 31, realizing the automatic adjustment of the position of the calibration element on the sliding member 32, ensuring adjustment efficiency and adjustment accuracy, and reducing manual adjustment errors.

[0059] In some embodiments, as shown in FIG3, the crossbeam 31 includes a foldable first crossbeam 311 (left crossbeam) and a second crossbeam 312 (right crossbeam). When the calibration device 100 is in operation, the first crossbeam 311 and the second crossbeam 312 are horizontally collinear, maximizing the length of the entire crossbeam 31 and facilitating calibration operations using the crossbeam module 30. When the calibration device 100 needs to be stored, the first crossbeam 311 and the second crossbeam 312 are folded into a vertical position to reduce the overall volume of the calibration device 100 and improve its portability and flexibility.

[0060] The first crossbeam 311 and the second crossbeam 312 are respectively provided with a rack 34, a slider 32 and a corresponding drive mechanism 33. The drive mechanism 33 on the first crossbeam 311 can drive the slider 32 on the first crossbeam 311 to slide along the first crossbeam 311, and the drive mechanism 33 on the second crossbeam 312 can drive the slider 32 on the second crossbeam 312 to slide along the second crossbeam 312.

[0061] In some embodiments, the output gear 331 can be directly mounted on the output shaft of the drive member 330, and the drive member 330 can directly drive the output gear 331 to rotate.

[0062] As shown in Figures 4 and 5, in some embodiments, the drive mechanism 33 further includes a drive gear 332 and a reduction gear set 333. The drive gear 332 is disposed on the output shaft of the drive member 330, and the reduction gear set 333 is disposed between the drive gear 332 and the output gear 331. The drive member 330 drives the drive gear 332 to rotate, and in turn drives the reduction gear set 333 and the output gear 331 to rotate in sequence.

[0063] The driving component 330 can be a drive motor, which can be fixedly mounted on the sliding component 32 via a motor mounting bracket. The reduction gear is mounted on the output shaft of the driving component 330. The reduction gear set 333 typically consists of multiple meshing gears and is installed between the drive gear 332 and the output gear 331. After the driving component 330 transmits power to the drive gear 332, the drive gear 332 transmits power to the output gear 331 through the reduction gear set 333, thereby driving the output gear 331 to rotate. In this process, the reduction gear set 333 can reduce the high speed of the driving component 330, and at the same time, according to the torque amplification principle of gear transmission, the output gear 331 can obtain a lower speed and a greater torque.

[0064] On the one hand, the lower rotational speed of the output gear 331 slows down the movement speed of the slider 32. When adjusting the position of calibration elements, a slower movement speed helps improve positioning accuracy. For example, when precisely calibrating a vehicle's ADAS system, it is necessary to move calibration targets and other elements precisely to specific positions. The presence of the reduction gear set 333 allows for a more refined adjustment process, enabling the slider 32 to stop more accurately at the target position, reducing positioning overshoot caused by excessive speed, and thus ensuring calibration accuracy. On the other hand, the greater torque ensures that the slider 32 can slide smoothly along the crossbeam 31, avoiding the phenomenon of insufficient power preventing it from sliding.

[0065] In some embodiments, the reduction gear set 333 includes a first gear 3331 and a second gear 3332 coaxially arranged, a third gear 3333 and a fourth gear 3334 coaxially arranged, and a fifth gear 3335 coaxially arranged with the output gear 331. The first gear 3331 meshes with the drive gear 332, the second gear 3332 meshes with the third gear 3333, and the fourth gear 3334 meshes with the fifth gear 3335.

[0066] Specifically, the number of teeth of the drive gear 332 is less than that of the first gear 3331. Since the drive gear 332 meshes with the first gear 3331, when power is transmitted from the drive gear 332 to the first gear 3331, the speed of the first gear 3331 will decrease, while the torque will increase, thereby achieving the effect of first-stage deceleration.

[0067] The number of teeth on the second gear 3332 is less than the number of teeth on the third gear 3333. Since the third gear 3333 meshes with the second gear 3332, when power is transmitted from the second gear to the third gear 3333, the speed of the third gear 3333 will decrease, while the torque will increase, thereby achieving the effect of second-stage deceleration.

[0068] The number of teeth on the fourth gear 3334 is less than the number of teeth on the fifth gear 3335. Since the fifth gear 3335 meshes with the fourth gear 3334, when power is transmitted from the fourth gear to the fifth gear 3335, the speed of the fifth gear 3335 will decrease, while the torque will increase, thus achieving the effect of the third-stage reduction.

[0069] In this embodiment, a three-stage reduction gear structure is adopted, which can achieve a large reduction effect in a small space. Through these three stages of reduction, the output gear 331 can obtain a suitable speed and sufficient torque to drive the slider 32 to slide stably along the crossbeam 31, thereby improving the sliding position control accuracy.

[0070] It is understood that in other embodiments, the use of a three-stage reduction gear structure is not limited to that of a three-stage reduction gear structure. For example, in some embodiments, a two-stage reduction gear structure can also be used. Compared with a three-stage reduction gear structure, a two-stage reduction gear structure has fewer parts, which can effectively reduce volume and cost. In other embodiments, a four-stage reduction gear structure can also be used. A four-stage reduction gear structure can provide a larger reduction ratio, which can further reduce the rotational speed of the output gear 331, increase torque output, and ensure that the sliding member 32 can operate smoothly under various complex working conditions.

[0071] Please refer to Figures 5 and 6. Figure 6 is a schematic diagram of the transmission relationship of the drive member 330, the reduction gear set 333, the output gear 331, the drive gear 332, and the rack 34 from another perspective. In some embodiments, the drive mechanism 33 also includes an encoder 334 and an encoder gear 335 connected to each other, the encoder gear 335 meshing with the reduction gear set 333.

[0072] Specifically, the encoder gear 335 can be configured to mesh with any one of the gears in the reduction gear set 333. When the reduction gear set 333 rotates, it will drive the encoder gear 335 to rotate synchronously. In this way, the encoder 334 can accurately measure the rotation angle and rotation speed of the encoder gear 335.

[0073] The encoder 334 can be roughly square or rectangular in shape. It can be a photoelectric encoder, magnetic encoder, etc. For example, the encoder 334 can be a photoelectric encoder. The encoder 334 includes a housing, a connecting shaft, a code disk, and a photoelectric sensor. The connecting shaft is rotatably mounted on the housing, with one end extending into the housing and the other end extending to the outside of the housing and connecting to the encoder gear 335. The code disk is located inside the housing and mounted on the connecting shaft. The photoelectric sensor is located inside the housing and close to the code disk. The code disk has regularly distributed light-transmitting and opaque areas. The photoelectric sensor (usually composed of a light-emitting diode and a photosensitive element) can detect changes in the light signal. When the encoder gear 335 rotates, the code disk rotates accordingly. When light passes through the light-transmitting area of ​​the code disk and shines on the photosensitive element, the photoelectric sensor generates a high-level signal; when the light is blocked by the opaque area, a low-level signal is generated. The combination of these high and low level signals forms a pulse sequence. By counting and analyzing these pulse sequences, the rotation angle and rotation speed of the encoder gear 335 can be accurately calculated.

[0074] Understandably, since the encoder gear 335 meshes with the reduction gear set 333, after the encoder 334 accurately measures the rotation angle and rotation speed of the encoder gear 335, based on the transmission relationship between the encoder gear 335 and the reduction gear set 333, as well as the transmission relationship between the slider 32 and the output gear 331, the position, speed, and direction of movement of the slider 32 on the crossbeam 31 can be accurately calculated. This ensures the position adjustment accuracy of the slider 32 and the calibration elements on the slider 32, and improves the accuracy and reliability of the calibration.

[0075] In some embodiments, as shown in FIG6, the encoder gear 335 meshes with the fifth gear 3335. Since the fifth gear 3335 is coaxially arranged with the output gear 331, the fifth gear 3335 can directly reflect the rotation angle and rotation speed of the output gear 331. Therefore, meshing the encoder gear 335 with the fifth gear 3335 can more accurately reflect the actual movement of the slider 32 and reduce cumulative errors.

[0076] In other words, if the encoder gear 335 meshes with other gears in the reduction gear set 333 (such as the first gear 3331), due to the multi-stage gear transmission between the first gear 3331 and the output gear 331, each stage of gear transmission will introduce a certain transmission ratio error (including manufacturing error, assembly error, wear error, etc.). These errors will accumulate continuously during the multi-stage transmission process, resulting in a deviation between the motion information of the sliding member 32 measured at the end and the actual motion information. However, if the encoder gear 335 meshes directly with the fifth gear 3335, this accumulated error can be minimized, and the measurement accuracy of the overall system can be improved.

[0077] Please refer to Figures 7 to 11. Figure 7 is a three-dimensional structural schematic diagram of the slider 32. Figure 8 is a three-dimensional structural schematic diagram of the slider 32 from another perspective. Figure 9 is a three-dimensional structural schematic diagram of the locking member 336. Figure 10 is a schematic diagram of the internal structure of the slider 32 when the crossbeam 31 is in the unfolded state; Figure 10 is a schematic diagram of the internal structure of the slider 32 when the crossbeam 31 is in the folded state.

[0078] In some embodiments, the slider 32 includes a slider 320 and a back plate 321. The back plate 321 covers the side of the slider 320 facing the crossbeam 31. The slider 320 and the back plate 321 surround to form a receiving cavity 3200. The drive gear 332 and the reduction gear set 333 are both installed in the receiving cavity 3200.

[0079] As shown in Figures 7 and 8, the sliding member 32 includes a sliding plate 320 and a back plate 321. The back plate 321 can be detachably installed on the sliding plate 320 by means of screwing, snap-fitting, etc. The side surface of the sliding plate 320 away from the back plate 321 is used to mount calibration targets, reflectors, lasers and other calibration elements to calibrate the vehicle's driver assistance system.

[0080] The sliding plate 320 and the back plate 321 surround to form a receiving cavity 3200. The drive gear 332, the encoder gear 335 and the reduction gear set 333 are all installed in the receiving cavity 3200 to improve the operational stability and safety of the drive mechanism 33.

[0081] Optionally, the drive unit 330, output gear 331, and encoder 334 are all mounted on the side of the back plate 321 opposite to the sliding plate 320 (the outer side of the back plate 321). The back plate 321 has a first shaft hole 3211, a second shaft hole 3212, and a connecting groove 3213. The first shaft hole 3211 allows the output shaft of the drive unit 330 to pass through, and the output shaft of the drive unit 330 is connected to the drive gear 332 after passing through the first shaft hole 3211. The second shaft hole 3212 allows the rotating shaft 323 to pass through. One end of the rotating shaft 323 is located in the receiving cavity 3200 for easy connection with the fifth gear 3335, and the other end of the rotating shaft 323 extends to the outer side of the back plate 321 through the second shaft hole 3212 for easy connection with the output gear 331. The connecting groove 3213 communicates with the receiving cavity 3200, and the encoder 334 is mounted in the connecting groove 3213 and at least partially extends into the receiving cavity 3200.

[0082] In some embodiments, the back plate 321 includes a bottom wall 3215 and a side wall 3216 surrounding the periphery of the bottom wall 3215. The side wall 3216 can be fixedly connected to the sliding plate 320 by means of screws or the like, thereby fixing the back plate 321 onto the sliding plate 320.

[0083] As shown in Figures 9 to 11, in some embodiments, the drive mechanism 33 further includes a locking member 336, which is rotatably mounted in the receiving cavity 3200. The locking member 336 is provided with an engaging part 3360. When the crossbeam 31 is in the unfolded state, the engaging part 3360 is separated from the reduction gear set 333 and the drive gear 332. When the crossbeam 31 is in the folded state, the locking member 336 rotates relative to the sliding member 32 under its own gravity, so that the engaging part 3360 engages with the reduction gear set 333 or the drive gear 332.

[0084] The locking element 336 can be a pendulum, which has a generally rod-shaped structure. One end of the locking element 336 can be rotatably mounted in the receiving cavity 3200 via a mounting shaft. The engaging part 3360 and the locking element 336 can be integrally formed to ensure the overall structural stability. Optionally, the engaging part 3360 can be a hook-shaped or tooth-shaped structure to facilitate engagement with the reduction gear set 333 or the drive gear 332.

[0085] As shown in Figure 10, when the crossbeam 31 is in the unfolded state, the locking member 336 is set vertically under its own weight. At this time, there is a certain distance between the meshing part 3360 on the locking member 336 and the reduction gear set 333 and the drive gear 332, ensuring that the drive gear 332 and the reduction gear set 333 can rotate freely, thereby driving the output gear 331 to rotate, so that the sliding member 32 can move normally, without affecting the normal calibration operation of the calibration equipment 100, and avoiding interference of the locking member 336 with the operation of the drive mechanism 33.

[0086] As shown in Figure 11, when the crossbeam 31 needs to be folded and stored, the crossbeam 31 will tilt relative to the horizontal direction. Under its own weight, the locking member 336 rotates relative to the sliding member 32, so that the meshing part 3360 on the locking member 336 meshes with the reduction gear set 333 or the drive gear 332, thereby locking the sliding member 32 and preventing the sliding member 32 from moving unexpectedly due to the rotation of the reduction gear set 333 during transportation or folding and storage. This ensures the safety and stability of the crossbeam 31 during the folding and storage process.

[0087] In some embodiments, when the crossbeam 31 is in a folded state, the engaging portion 3360 can engage with the drive gear 332. Since the drive gear 332 is directly connected to the drive member 330, the torque of the drive gear 332 is relatively small compared to the gears in the reduction gear set 333. Therefore, by configuring the engaging portion 3360 to engage with the drive gear 332, it is easier to overcome the torque of the drive gear 332 and achieve locking of the slider 32.

[0088] It is understood that in other embodiments, during the folding and storage of the crossbeam 31, the engaging portion 3360 may also be configured to engage with any one of the gears in the reduction gear set 333. Furthermore, during the folding and storage of the crossbeam 31, the engaging portion 3360 may also be configured to engage with the encoder gear 335.

[0089] In some embodiments, the slider 32 is provided with an unlocking hole 3217 (see FIG8) for the unlocking tool 200 to extend into the receiving cavity 3200, and the unlocking hole 3217 corresponds to the position of the locking member 336.

[0090] As shown in Figure 11, the unlocking hole 3217 can be a square hole or a round hole, etc. The unlocking hole 3217 is located on the slider 32 and communicates with the receiving cavity 3200. It should be noted that the unlocking hole 3217 corresponds to the position of the locking member 336, ensuring that the unlocking tool can extend into the receiving cavity 3200 through the unlocking hole 3217 and can move the locking member 336. Optionally, the unlocking hole 3217 can be located on the back plate 321. In some embodiments, the unlocking hole 3217 can be located on the bottom sidewall 3216 of the back plate 321, so that the unlocking tool can be inserted into the receiving cavity 3200 through the unlocking hole 3217 at the bottom.

[0091] The unlocking tool can be a rod-shaped structure. When it is necessary to unlock the locking member 336, the operator inserts the unlocking tool into the receiving cavity 3200 through the unlocking hole 3217 and applies a suitable force to the locking member 336 by operating the unlocking tool, so that the locking member 336 rotates accordingly. Finally, the locking member 336 separates from the drive gear 332, thereby releasing the lock on the sliding member 32.

[0092] In this embodiment, by opening an unlocking hole 3217, the unlocking tool can be inserted into the receiving cavity 3200 through the unlocking hole 3217 to unlock the slider 32. The unlocking process is convenient and quick, allowing the operator to complete the unlocking process quickly without disassembling the slider 32.

[0093] [Corrected according to Rule 91, 06.02.2026] Please refer to Figures 12 and 13. Figure 12 is a partial three-dimensional structural schematic diagram of the crossbeam 31, and Figure 13 is a partial three-dimensional structural schematic diagram of the crossbeam module 30. In some embodiments, the crossbeam 31 is provided with a mounting groove 313 and a receiving groove 314 on the side facing the slider 32. The mounting groove 313 and the receiving groove 314 are arranged sequentially along the height direction of the crossbeam 31, and both the mounting groove 313 and the receiving groove 314 extend through the opposite ends of the crossbeam 31 in the length direction. Optionally, the mounting groove 313 is disposed above the receiving groove 314, and the mounting groove 313 and the receiving groove 314 are connected to facilitate the meshing of the rack 34 in the mounting groove 313 with the output gear 331 in the receiving groove 314.

[0094] In addition, the receiving slot 314 can also be used to receive the drive unit 330 and the encoder 334. Specifically, the end of the drive unit 330 facing the crossbeam 31 and the end of the encoder 334 facing the crossbeam 31 can be respectively received in the receiving slot 314 to improve the overall layout compactness and save space.

[0095] In some embodiments, a guide rail 315 is provided at the bottom of the crossbeam 31, and a slider 324 is connected to the slider 32, which is slidably mounted on the guide rail 315.

[0096] As shown in Figure 13, the guide rail 315 is arranged along the length of the crossbeam 31, and the guide rail 315 can be fixedly installed on the crossbeam 31 by means of screw connection, snap connection or other methods.

[0097] The slider 32 also includes an extension plate 325, which is perpendicularly connected to the back plate 321 and extends toward the crossbeam 31. The slider 324 can be installed on the side of the extension plate 325 facing the crossbeam 31. Optionally, the slider 324 can be fixedly installed on the extension plate 325 by means of screwing, snap-fitting, or other methods.

[0098] The slider 324 is slidably mounted on the guide rail 315. When the drive component 330 drives the output gear 331 to rotate relative to the rack 34, the slider 324 on the slider 32 can slide relative to the guide rail 315 at the bottom of the crossbeam 31, ensuring that the slider 32 runs smoothly relative to the crossbeam 31.

[0099] In some embodiments, a limiting groove 316 is provided at the bottom of the crossbeam 31, the limiting groove 316 is arranged along the length direction of the crossbeam 31, and the guide rail 315 is installed in the limiting groove 316.

[0100] In some embodiments, the slider 32 is further provided with a limiting plate 326. One end of the limiting plate 326 is fixedly connected to the slider 32, and the other end of the limiting plate 326 extends to the top of the crossbeam 31 and is limited and cooperated with the top surface of the crossbeam 31, thereby further improving the stability of the slider 32 during the sliding process.

[0101] Based on the same inventive concept, this application also provides a calibration system, which includes the calibration device 100 in the above embodiments and a diagnostic instrument, and the diagnostic instrument is communicatively connected to the calibration device.

[0102] The diagnostic tool can be a flat panel diagnostic tool for easy carrying and transportation. Optionally, a vision camera is provided on the crossbeam 311 of the calibration device. The vision camera is in communication connection with the diagnostic tool, which can be used to receive vehicle image data captured by the vision camera.

[0103] Optionally, the calibration system may also include calibration elements such as targets, mirrors, and lasers, which can be mounted on the sliding plate 320.
