Description

Technical Field

[0001] The present application relates to the field of vehicle detection technology, and in particular to a vehicle measurement system. Background Art

[0002] The vehicle's four-wheel alignment is to adjust the positioning parameters of the vehicle's four wheels (two front wheels and two rear wheels) to optimize the geometric angle between the vehicle's suspension system and the wheels. ADAS (Advanced Driver Assistant Systems) calibration refers to the use of external measuring equipment to calibrate the position, function and parameters of the vehicle's sensors (such as cameras, radars, ultrasonic sensors, etc.) to ensure that they can accurately perceive the environmental information around the vehicle.

[0003] Before performing four-wheel alignment and ADAS calibration on a vehicle, the relative position between the calibration structure and the vehicle to be inspected needs to be ensured. This requires that the calibration structure can be finely adjusted in translation in multiple directions and finely adjusted in swing in multiple planes.

[0004] Therefore, the problem existing in the current vehicle measurement system is that multiple groups of adjustment structures are integrated together, resulting in a complex overall structure, which makes assembly and maintenance difficult. In addition, the adjustment structures of different groups are often interrelated in structure and the adjustment results are also interrelated. Multiple groups of adjustment structures need to be operated sequentially and individually, which often requires repeated adjustments, resulting in inconvenient adjustment and low efficiency.

[0052] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

The terms "first" and "second" are only used for the convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0054] In order to illustrate the technical solution described in this application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0055] See also Figure 1 As shown, the embodiment of the present application provides a vehicle measurement system 100, which includes a base 1, a column 3, a lifting drive assembly 9, and a beam 7. Figure 2As shown, the base 1 includes a base body 11 and a first adjustment assembly 12 disposed on the base body 11. The base body 11 is used to be disposed on a fixed surface such as the ground to serve as a support for the entire vehicle measurement system 100; Figures 4 to 6 As shown, the column 3 includes a column body 31 and a second adjustment component 33 disposed on the column body 31. The column body 31 is connected to the first adjustment component 12. The first adjustment component 12 is used to drive the column body 31 to rotate around the first axis P (please refer to Figure 3 As shown), the first axis P is parallel to the third direction Z; see Figure 4 and Figure 5 As shown, the lifting drive assembly 9 is arranged on the column body 31 and connected to the second adjustment assembly 33, which is used to drive the second adjustment assembly 33 to translate along the third direction Z; the second adjustment assembly 33 is used to connect the crossbeam 7 and drive the crossbeam 7 to rotate around the second axis Q and around the third axis M. Please refer to Figure 7 As shown; the second axis Q is parallel to the first direction X, and the third axis M is perpendicular to the first direction X; the first direction X and the third direction Z are perpendicular to each other.

[0056] In this way, through the cooperation of the first adjusting component 12, the lifting drive component 9 and the second adjusting component 33, the beam 7 can achieve translation along the third direction Z, rotation around the first axis P, rotation around the second axis Q and rotation around the third axis M, thereby realizing multi-dimensional adjustment of the position of the beam 7, and enabling the beam 7 to be adjusted to the required position and posture to meet the needs of vehicle measurement.

[0057] In the multiple groups of adjustment structures for adjusting the position and posture of the beam 7, assuming that the adjustment of one dimension corresponds to a group of adjustment structures, in the embodiment of the present application, the first adjustment component 12 (corresponding to at least one group of adjustment structures) is arranged on the base body 11, the lifting drive component 9 (corresponding to at least one group of adjustment structures) is arranged on the column 3, and the second adjustment component 33 (corresponding to at least two groups of adjustment structures) is arranged on the lifting drive component 9, so that the multiple groups of adjustment structures are dispersedly arranged, and the structures of the first adjustment component 12, the lifting drive component 9 and the second adjustment component 33 can be simplified respectively. At the same time, this reduces the structural correlation between the adjustment structures, and then reduces the correlation between the adjustment results, avoiding the problem of repeated and multiple adjustments due to the correlation of the adjustment structures, which is conducive to improving the adjustment efficiency.

[0058] In addition, the first adjustment component 12 , the lifting drive component 9 , and the second adjustment component 33 are dispersedly arranged, which can reduce the difficulty of assembling and repairing the first adjustment component 12 , the lifting drive component 9 , and the second adjustment component 33 .

[0059] See also Figure 1 and Figure 2As shown, in the vehicle measurement system 100, the crossbeam 7 further includes a plurality of image acquisition modules 72 and a calibration member 73. The image acquisition modules 72 are respectively arranged at opposite ends of the crossbeam body 71 along the first direction X, and the calibration member 73 is arranged on the crossbeam body 71. During the vehicle measurement process, the image acquisition module 72 is used to acquire image information of vehicle components (such as four wheels), and the calibration member 73 is used as a reference point for the vehicle's sensor system to detect, so as to provide feedback on whether the vehicle's sensor system is accurate.

[0060] In one embodiment, the first adjustment assembly 12 is further used to drive the column body 31 to move along the first direction X and the second direction Y. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0061] In this embodiment, the first direction X, the second direction Y and the third direction Z are arranged perpendicular to each other, and their specific corresponding directions are not limited. Figure 1 and Figure 2 As shown, for ease of description and understanding, the second direction Y is defined as the direction from the column 3 to the vehicle, with the driving position as a reference, the second direction Y is the front-to-back direction, the first direction X is the left-to-right direction, and the third direction Z is the vertical direction.

[0062] In one embodiment, the image acquisition module 72 includes two cameras at each end of the crossbeam body 71 along the first direction X. The two cameras of one image acquisition module 72 correspond to two wheels on one side of the vehicle to be inspected. For example, the two cameras located at the left end of the crossbeam 7 are used to acquire image information of the left front wheel and the left rear wheel.

[0063] One or more calibration members 73 may be provided on the crossbeam body 71. The multiple calibration members 73 are arranged on the crossbeam body 71 at intervals along the first direction X. Figure 1 Furthermore, at least one calibration member 73 may be able to slide on the crossbeam body 71 along the first direction X to meet the measurement requirements of different components of the vehicle to be inspected.

[0064] See also Figure 2 and Figure 3 As shown, in one embodiment, the first adjustment component 12 includes a first translation member 121, a second translation member 123 and a first rotating member 125. The first translation member 121 is arranged on the base body 11, the second translation member 123 is arranged on the first translation member 121, and the first rotating member 125 is arranged on the second translation member 123. The first translation member 121 can drive the second translation member 123 and the first rotating member 125 to reciprocate in the left and right directions, the second translation member 123 can drive the first rotating member 125 to move in the front and rear directions, and the first rotating member 125 can drive the column 3 to rotate around the first axis P.

[0065] Specifically, see Figure 3 As shown, the first translation member 121 includes a meshing first screw rod 1212 and a first nut 1213, and a first support plate 1214 fixedly connected to the first nut 1213; the second translation member 123 includes a meshing second screw rod 1232 and a second nut 1233, and a second support plate 1234 fixedly connected to the second nut 1233; the first rotating member 125 includes a meshing first worm 1252 and a first worm wheel 1253. The central axis of the first screw rod 1212 is parallel to the first direction X, and the first screw rod 1212 is rotatably installed on the base body 11 around its own central axis, and the first nut 1213 is slidably installed on the base body 11 along the first direction X; the central axis of the second screw rod 1232 is parallel to the second direction Y, and the second screw rod 1232 is rotatably installed on the first support plate 1214 around its own central axis, and the second nut 1233 is slidably installed on the first support plate 1214 along the second direction Y; the lower end of the column body 31 is coaxially connected with the first worm gear 1253, and the central axis of the first worm gear 1253 is the first axis P. The first worm gear 1253 is rotatably installed on the second support plate 1234 around the first axis P, and the central axis of the first worm 1252 is perpendicular to the first axis P, and the first worm 1252 is rotatably installed on the second support plate 1234 around its own central axis.

[0066] The rotation of the first screw rod 1212 can be converted into the translation of the first nut 1213 along the first direction X, thereby driving the first support plate 1214 to reciprocate along the first direction X; the rotation of the second screw rod 1232 can be converted into the translation of the second nut 1233 along the second direction Y, thereby driving the second support plate 1234 to reciprocate along the second direction Y; the rotation of the first worm gear 1252 can be converted into the rotation of the first worm wheel 1253 perpendicular thereto, thereby driving the column 3 to rotate around the first axis P.

[0067] Please continue reading Figure 3 As shown, in one embodiment, the first translation member 121 further includes a first driving member 1211, the second translation member 123 further includes a second driving member 1231, and the first rotating member 125 further includes a third driving member 1251. The first driving member 1211 is fixedly mounted on the base body 11, and its output end is connected to the first screw rod 1212, and is used to drive the first screw rod 1212 to rotate; the second driving member 1231 is fixedly mounted on the first support plate 1214, and its output end is connected to the second screw rod 1232, and is used to drive the second screw rod 1232 to rotate; the third driving member 1251 is fixedly mounted on the second support plate 1234, and its output end is connected to the first worm 1252, and is used to drive the first worm 1252 to rotate.

[0068] The rotation of the first screw rod 1212, the second screw rod 1232 and the first worm gear 1252 is controlled by the first driving member 1211, the second driving member 1231 and the third driving member 1251, and no manual adjustment is required, which can save manual operation intensity; at the same time, since the height of the base 1 is usually small, the positions of the first screw rod 1212, the second screw rod 1232 and the first worm gear 1252 are relatively low. The rotation of the first screw rod 1212, the second screw rod 1232 and the first worm gear 1252 is controlled by the first driving member 1211, the second driving member 1231 and the third driving member 1251, which can avoid the inconvenience caused by the operator bending over for multiple operations.

[0069] The first driving member 1211 , the second driving member 1231 , and the third driving member 1251 may be motors, respectively.

[0070] In one embodiment, if Figure 1 As shown, the vehicle measurement system 100 may include a main control module 83, which is fixedly arranged on the column body 31 and maintains a certain height, optionally a fixed height, for operation by an operator. The main control module 83 is connected to the first drive member 1211, the second drive member 1231 and the third drive member 1251, and the operator can operate the start and stop of the first drive member 1211, the second drive member 1231 and the third drive member 1251 through the main control module 83.

[0071] In addition, the main control module 83 can be connected to the lifting drive assembly 9 to control the start and stop of the lifting drive assembly 9. Specifically, the main control module 83 is connected to the lifting member 91 of the lifting drive assembly 9 and controls the lifting and lowering of the push rod of the lifting member 91.

[0072] Furthermore, in one embodiment, the vehicle measurement system 100 may further include a control terminal (not shown), which is connected to the main control module 83 via a wired communication method or a wireless communication method. An operator can remotely control the main control module 83 on the control terminal, thereby controlling the first translation member 121, the second translation member 123 and the first rotation member 125.

[0073] See also Figure 3As shown, the first translation member 121 also includes one or more first guide rails 1215 and a first slider (not shown) arranged along the first direction X. The first guide rail 1215 is arranged on the base body 11, for example, on the surface of the lower shell 112 of the base body 11. The first slider is slidably arranged on the first guide rail 1215, and the first support plate 1214 is also fixedly arranged on the first slider. The second translation member 123 also includes a plurality of second guide rails 1235 and a second slider (not shown) arranged along the second direction Y. The second guide rail 1235 is fixedly arranged on the first support plate 1214. The second slider is slidably arranged on the second guide rail 1235, and the second support plate 1234 is also fixedly arranged on the second slider.

[0074] like Figure 2 As shown, in the base body 11, a substantially closed accommodation space is defined between the lower shell 112 and the upper shell 111, and the first translation member 121, the second translation member 123 and the first rotation member 125 are arranged in the accommodation space. The first adjustment assembly 12 may further include a connecting member (not shown), which is fixedly connected between the first worm gear 1253 and the column body 31 and passes through the upper shell 111. A rotating bearing (not shown) may be arranged between the outer periphery of the connecting member and the upper shell 111 to provide support for the rotation of the connecting member and reduce the friction between the connecting member and the base body 11.

[0075] The base body 11 needs to maintain the stability of the entire vehicle measurement system 100 in the vertical direction, so it needs to have a certain area and weight. In the embodiment of the present application, the first adjustment component 12 is arranged in the accommodation space of the base body 11, which just utilizes the area and volume of the base body 11, and the first adjustment component 12 does not need to occupy space outside the base body 11; it also provides the weight of the entire base 1, and the center of gravity of the entire base 1 can be kept at a lower position.

[0076] In addition, the first adjustment assembly 12 does not need to rise or fall with the column body 31 , which further reduces the energy consumption of the entire vehicle measurement system 100 .

[0077] Next, see Figure 4 and Figure 5 As shown, the column body 31 includes a fixed column 311 and a lifting column 312. The lower end of the fixed column 311 is fixedly connected to the connecting piece of the first adjustment component 12 and remains fixed in the third direction Z. The lifting column 312 is slidably connected to the fixed column 311 along the third direction Z. The lifting drive component 9 is arranged on the fixed column 311 and is used to drive the lifting of the lifting column 312. The second adjustment component 33 is arranged on the lifting column 312 to rise and fall with the lifting column 312, thereby realizing the lifting and lowering adjustment of the crossbeam 7.

[0078] In the embodiment of the present application, the lifting and lowering of the column body 31 is achieved by relative sliding of the lifting column 312 and the fixed column 311. On the one hand, the column body 31 has a variable height. When, for example, the vehicle measurement system 100 is transported, the lifting column 312 can be lowered to the lowest point for easy storage and transportation.

[0079] Please refer to Figure 4 and Figure 5 As shown, in one embodiment, the lifting drive assembly 9 includes a lifting member 91 and a driving chain 92. The lifting member 91 is fixedly connected to the fixed column 311 and has a push rod that can be lifted and lowered away from the base 1 in the third direction Z. One end of the driving chain 92 is connected to the fixed column 311, and the driving chain 92 slides around the top of the lifting member 91 (for example, a pulley is provided at the top of the lifting member 91), and the other end of the driving chain 92 is fixedly connected to the second adjusting assembly 33.

[0080] Thus, when the push rod of the lifting member 91 rises a certain distance, the parts of the driving chain 92 on both sides of the lifting member 91 rise and fall the same distance, and the second adjustment component 33 moves twice the distance. The purpose of such a setting is to achieve a large distance movement of the second adjustment component 33 through a small movement of the lifting member 91, which is conducive to further reducing the height of the fixed column 311 in the third direction Z, and further, it is conducive to reducing the overall height and volume of the vehicle measurement system 100.

[0081] The form of the driving chain 92 is not limited, and it can be a chain, or a wire rope, or a rope made of other materials, as long as it can bear the pulling force that causes the second adjustment component 33 to rise.

[0082] One end of the driving chain 92 connected to the fixed column 311 is located at the rear side of the fixed column 311 , the other end of the driving chain 92 is located at the front side of the fixed column 311 , and the second adjustment assembly 33 is located at the front side of the fixed column 311 .

[0083] See also Figure 5 As shown, the column 3 further includes a bracket 313 and a guide roller 314. The bracket 313 is arranged at the front side of the fixed column 311 and is fixedly connected to the rear side of the second adjustment assembly 33 and the other end of the driving chain 92. The bracket 313 is connected to the guide roller 314. The lifting column 312 is provided with a guide groove 3120 opened along the third direction Z, and the guide roller 314 is arranged in the guide groove 3120. In this way, the other end of the driving chain 92 drives the bracket 313 and the second adjustment assembly 33 to rise together, and the cooperation between the guide roller 314 and the guide groove 3120 realizes the guidance of the movement of the bracket 313 along the third direction Z.

[0084] Furthermore, by setting the shape of the guide roller 314 , such as an I-shape, and passing through the lifting column 312 , the relative position between the bracket 313 and the lifting column 312 can be restricted, thereby preventing the guide roller 314 from escaping from the guide groove 3120 .

[0085] In an alternative embodiment, see Figure 4 and Figure 5 As shown, the lifting column 312 can be configured to slide around the fixed column 311 .

[0086] In an alternative embodiment, see Figure 5 As shown, the guide rollers 314 are arranged on opposite sides of the bracket 313 along the first direction X, and the guide slots 3120 are opened on opposite sides of the lifting column 312 along the first direction X. In more embodiments, the guide rollers 314 and the guide slots 3120 are allowed to be arranged at other positions, such as opposite sides in other directions, or multiple sides.

[0087] Please continue reading Figure 4 and Figure 5 As shown, the fixed column 311 is a hollow structure with an opening at the upper end, and the lifting member 91 is arranged inside the fixed column 311, and the top end of the lifting member 91 can pass through the upper end opening of the fixed column 311. The purpose of this arrangement is to utilize the internal space of the fixed column 311, and at the same time, the fixed column 311 can provide a certain degree of protection for the lifting member 91. In more embodiments, the lifting column 312 can be arranged side by side with the fixed column 311.

[0088] Next, see Figures 6 to 8 As shown, in one embodiment, the second adjustment component 33 includes: a fixed plate 331, a movable plate 332, a first fine-tuning module 333 and a second fine-tuning module 335; the fixed plate 331 is fixedly connected to the drive chain 92 of the lifting drive component 9 through a bracket 313, and the movable plate 332 is rotatably connected to the fixed plate 331 around the second axis Q; the first fine-tuning module 333 is connected between the fixed plate 331 and the movable plate 332, and is used to drive the movable plate 332 to rotate around the second axis Q; the second fine-tuning module 335 is arranged on the movable plate 332, and is used to be fixedly connected to the beam 7, and the second fine-tuning module 335 is used to drive the beam 7 to rotate around the third axis M.

[0089] The rotation of the beam 7 around the second axis Q is manifested as the overall pitching of the beam 7 forward and backward, and the rotation of the beam 7 around the third axis M is manifested as the left and right sides of the beam 7 swinging up and down.

[0090] In the embodiment of the present application, the second adjustment component 33 is used to drive the beam 7 to rotate around the second axis Q and around the third axis M. The two rotations are separated from the translation of the beam 7 in the first direction X and the second direction Y. The beam 7 does not need to perform translational movement in the first direction X and the second direction Y on the second adjustment component 33. Therefore, it will not affect the rotation of the beam 7, and will not affect the action of the first fine-tuning module 333 and the second fine-tuning module 335 in the second adjustment component 33.

[0091] For comparison, please refer to the assumption that the second adjustment component 33 can also drive the cross beam 7 to translate in the first direction X. If the midpoint of the cross beam 7 in the first direction X is not aligned with the second adjustment component 33, when the cross beam 7 is adjusted to pitch forward and backward, the image acquisition modules 72 at both ends of the cross beam body 71 are at different distances from the vehicle to be inspected, and the acquired images will be different, affecting the inspection result. Therefore, the pitch adjustment can only be performed after the cross beam 7 is adjusted to the right position along the first direction X.

[0092] Similarly, assuming that the second adjustment component 33 can also drive the beam 7 to translate in the first direction X, then if the midpoint of the beam 7 in the first direction X is not aligned with the second adjustment component 33, then when the beam 7 swings up and down, the image acquisition modules 72 at both ends of the beam body 71 are at different distances from the vehicle to be inspected, affecting the detection result.

[0093] In the embodiment of the present application, the second fine-tuning module 335 is arranged on the movable plate 332 and is fixedly connected to the beam 7 to drive the beam 7 to rotate around the third axis M. Therefore, the second fine-tuning module 335 can be fixedly connected to the midpoint of the beam 7 along the first direction X to ensure that the left and right sides of the beam 7 always remain symmetrical during the pitch adjustment process and the up and down swing process. Such a setting can improve the adjustment efficiency. In the process of the beam translating along the first direction X, translating along the second direction Y, translating along the third direction Z, and rotating around the first axis P, the left and right sides of the beam 7 also always remain symmetrical.

[0094] In addition, the structure of the second adjustment component 33 can be simplified and the volume can be reduced.

[0095] Please refer to Figures 6 to 8 As shown, the first fine-tuning module 333 includes a third screw rod 3333, a third nut 3334 and a connecting rod 3338. The third screw rod 3333 is rotatably mounted on the movable plate 332. The central axis of the third screw rod 3333 is perpendicular to the first direction X. The third nut 3334 is engaged with the third screw rod 3333. Fig. 9 As shown, the first end of the connecting rod 3338 is rotatably mounted on the fixed plate 331 around the fourth axis N, and the other end of the connecting rod 3338 is rotatably connected to the third nut 3334 around the fifth axis L. The fifth axis L and the fourth axis N are both parallel to the second axis Q.

[0096] When the third screw rod 3333 rotates, the third nut 3334 moves along the third screw rod 3333. Fig. 9 As shown, since the third nut 3334 is rotatably connected to the other end of the connecting rod 3338, the movable plate 332 is pushed to rotate around the second axis Q to adapt to the length of the connecting rod 3338. Fig. 9 As shown, when the third nut 3334 slides upward along the third screw rod 3333, the angle between the movable plate 332 and the fixed plate 331 becomes smaller.

[0097] See also Figure 7 and Figure 8 As shown, in one embodiment, the first fine-tuning module 333 further includes a third guide rail 3336 and a third slider 3337. The third guide rail 3336 is fixedly arranged on the movable plate 332 and is parallel to the central axis of the third screw rod 3333. The third slider 3337 is arranged on the third guide rail 3336, and the third slider 3337 is fixedly connected to the third nut 3334. When the third nut 3334 moves along the third screw rod 3333, the third slider 3337 is driven to move synchronously along the third guide rail 3336. The other end of the connecting rod 3338 is connected to the third slider 3337 by rotating around the fifth axis L.

[0098] Through the sliding configuration of the third guide rail 3336 and the third slider 3337, the third slider 3337 can limit the third nut 3334 from rotating around the third screw rod 3333. There is no need to set an additional circumferential limiting structure for the third nut 3334, and the torque of the third screw rod 3333 is avoided from being transmitted to the connecting rod 3338 through the third nut 3334, thereby avoiding the problem of the connecting rod 3338 being deflected and easily stuck, thereby ensuring the smooth front and rear pitch adjustment of the movable plate 332.

[0099] In addition, through the configuration of the third guide rail 3336 and the third slider 3337, the connecting rod 3338 can be arranged away from the third nut 3334 in the first direction X. This is conducive to the arrangement of the structure in the first fine-tuning module 333, and also enables the second adjustment component 33 to have a certain volume, so as to have a sufficiently large connection area with the bracket 313, the beam body 71, etc., so as to ensure the connection stability between the second adjustment component 33 and the bracket 313 and the beam body 71.

[0100] like Figure 7 and Figure 8 As shown, in one embodiment, the third guide rail 3336 and the third slider 3337 are each configured as two, and are respectively located on both sides of the third screw rod 3333 in the first direction X. The connecting rod 3338 can be configured as a group, hinged to one of the third sliders 3337, or configured as two groups, respectively hinged to the third sliders 3337, such as Figure 8shown.

[0101] In this way, the two third sliders 3337 slide on the two sides of the third screw rod 3333 respectively, which makes the forces on the third sliders 3337 on both sides more balanced, which is conducive to the sliding of the third sliders 3337.

[0102] like Figure 7 and Figure 8 As shown, the two third sliders 3337 are fixedly connected via a connecting rod 3340. Of course, in the second direction Y, the connecting rod 3340 is arranged to avoid the third screw rod 3333.

[0103] Please continue reading Figure 7 and Figure 8 As shown, the first fine-tuning module 333 also includes a first bevel gear 3332 and a second bevel gear 3335 that are meshed with each other, the first bevel gear 3332 is coaxially connected to one end of the third screw rod 3333, such as being coaxially fixedly connected to the upper end of the third screw rod 3333, the second bevel gear 3335 is rotatably mounted on the movable plate 332, and the central axis of the second bevel gear 3335 is perpendicular to the central axis of the first bevel gear 3332. By rotating the second bevel gear 3335, the rotation of the first bevel gear 3332 and the third screw rod 3333 can be achieved.

[0104] One end of the second bevel gear 3335 is connected to the first hand wheel 3331 through the first rotating rod 3341, so that the operator can rotate the second bevel gear 3335. The purpose of this arrangement is to allow the operator to operate the rotation of the third screw rod 3333 from the left or right side of the second adjustment component 33. This is in consideration of Figure 1 As shown, an electric control box 82 is generally arranged above the second adjustment assembly 33 , so the rotation operation of the third screw rod 3333 can avoid the electric control box 82 .

[0105] In other optional embodiments, if the space above or below the second adjustment assembly 33 allows, the first bevel gear 3332 and the second bevel gear 3335 may be omitted, and the first hand wheel 3331 may be directly provided at the upper end or the lower end of the third screw rod 3333.

[0106] See also Figure 7 and Figure 8 As shown, a first fixed block 3311 is provided on the side surface of the fixed plate 331 facing the movable plate 332, and a second fixed block 3321 is provided on the side surface of the movable plate 332 facing the fixed plate 331 (due to viewing angle reasons, the second fixed block 3321 is shown separately from the movable plate 332), and the first fixed block 3311 and the second fixed block 3321 are hinged about the second axis Q.

[0107] In order to improve the hinge stability of the fixed plate 331 and the movable plate 332, as shown in FIG. Figure 7 and Figure 8 As shown, two first fixing blocks 3311 and two second fixing blocks 3321 are each provided, and are arranged at intervals along the first direction X, for example, arranged at positions substantially corresponding to the two third sliding blocks 3337 .

[0108] See also Figure 7 and Figure 8 As shown, the second fine-tuning module 335 includes a second worm 3352 and a second worm wheel 3353 that are meshed with each other. The second worm 3352 is rotatably mounted on the movable plate 332. The central axis of the second worm 3352 is perpendicular to the first direction X. The second worm wheel 3353 is rotatably mounted on the movable plate 332. The central axis of the second worm wheel 3353 is the third axis M. The second worm wheel 3353 is fixedly connected to the center point of the beam body 71 along the first direction X.

[0109] The rotation of the second worm 3352 can be converted into the rotation of the second worm wheel 3353 , thereby realizing the rotation of the beam 7 around the third axis M, which can adjust the height of the left and right sides of the beam 7 .

[0110] See also Figure 7 and Figure 8 As shown, the second fine-tuning module 335 includes a third support plate 3356, which is fixedly disposed on a side surface of the movable plate 332 facing the fixed plate 331 (similarly, the third support plate 3356 is shown in a state separated from the movable plate 332), and the second worm 3352 passes through the third support plate 3356 and rotates in the third support plate 3356. In an optional embodiment, a bearing (not shown) may be disposed in the third support plate 3356 for supporting the second worm 3352.

[0111] Optionally, the third support plate 3356 may be structurally arranged so that the third support plate 3356 simultaneously supports the third screw rod 3333 , for example, supports the lower end of the third screw rod 3333 .

[0112] In one embodiment, see Figure 7 and Figure 8 As shown, the second worm 3352 is located between the third nut 3334 and a third slider 3337, and the second worm wheel 3353 is located on one axial side of the third screw 3333, such as the lower end. The first fine-tuning module 333 and the second fine-tuning module 335 are arranged crosswise and do not affect each other, and use each other's space, which makes the structural arrangement of the second adjustment component 33 more balanced.

[0113] In addition, in order to facilitate the rotation of the third screw rod 3333, in one embodiment, Figure 7 and Figure 8As shown, the second fine-tuning module 335 also includes a third bevel gear 3354 and a fourth bevel gear 3355 that are meshed with each other. The third bevel gear 3354 is coaxially arranged at one axial end of the second worm 3352, such as the axial upper end. The fourth bevel gear 3355 is rotatably mounted on the movable plate 332. The central axis of the fourth bevel gear 3355 is perpendicular to the central axis of the third bevel gear 3354.

[0114] like Figure 7 and Figure 8 As shown, the fourth bevel gear 3355 is connected to the second hand wheel 3351 via the second rotating rod 3357 , so as to facilitate the operator to operate the fourth bevel gear 3355 .

[0115] Similarly, the second hand wheel 3351 can be arranged so that the rotation of the second worm 3352 avoids the electric control box 82. In other optional embodiments, the second hand wheel 3351 can be directly connected to the axial upper end or the axial lower end of the second worm 3352 if permitted.

[0116] In a specific embodiment, the second hand wheel 3351 and the first hand wheel 3331 are arranged relatively to each other along the first direction X, and are located on the left and right sides of the second adjustment component 33 , respectively, which is adapted to the operating habits of the operator.

[0117] See also Figure 6 As shown, in one embodiment, the vehicle measurement system 100 further includes a plurality of rangefinders 81 ( Figure 6 The distance meter 81 is arranged on the cross beam 7 and / or the second fine adjustment module 335, and moves synchronously with the cross beam 7. The distance meter 81 is used to measure the distance between the position of the cross beam 7 and the ground and the distance to the reference position in front. In a specific embodiment, if the height of the base 1 is constant, the distance meter 81 can be used to measure the distance between the cross beam 7 and the upper surface of the base 1.

[0118] In addition, in one embodiment, the vehicle measurement system 100 further includes a plurality of inclination detection elements (not shown), which are arranged on the cross beam 7 and are used to reflect whether the left and right side parts of the cross beam 7 are horizontal, including the inclination angle of the cross beam body 71 relative to at least one of the first direction X, the second direction Y and the third direction X, thereby providing a reference for adjusting the cross beam 7. For example, the inclination detection element may include a gyroscope, and the inclination detection element may be arranged on the rear side of the cross beam body 71; further, a plurality of inclination detection elements may be arranged on the cross beam body 71 in a row.

[0119] In addition, in one embodiment, the base 1 of the vehicle measurement system 100 further includes a wheel assembly (not shown) disposed at the lower end of the base body 11, so that the base body 11 and its first adjustment assembly 12 can move on the ground, allowing the vehicle measurement system 100 to be quickly moved to a desired position. The first translation member 121 and the second translation member 123 can have a smaller adjustment accuracy, which is conducive to improving the adjustment efficiency.

[0120] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
