[0026] This research revealed that as the automotive industry continues to develop and market demand for vehicle diversification continues to rise, the automotive manufacturing sector is gradually adopting multi-model mixed-line production methods to manufacture different levels and configurations of vehicles on the same production line. As a key process in vehicle quality control, vehicle dimension inspection is ill-suited to the frequent model switching scenarios in mixed-line production, failing to adequately balance multi-model compatibility and measurement accuracy. Current vehicle dimension measurement devices primarily rely on fixed measuring devices combined with manual measurement. Different vehicle models exhibit significant differences in body structure and key dimensional parameters, and the process standards for details such as chassis layout and bumper contours also vary. The fixed measuring devices' inspection stations and sensor layouts are tied to specific vehicle models, requiring large-scale mechanical adjustments and recalibration when switching models. In multi-model mixed-line production, existing vehicle dimension measurement devices cannot adapt to the high-frequency model switching scenarios on the production line, struggling to balance multi-model versatility, measurement accuracy, and measurement efficiency.

[0027] Specifically, in existing measuring devices, the position and angle adjustment mechanisms of the measuring units (such as the top scanning component or the side measuring component) are relatively rigid, lacking a flexible rotation drive and lifting displacement coordination mechanism. This makes it difficult to quickly adapt to the measurement needs of different angles, such as the roof, front, rear, and sides of the vehicle. This results in long single-change times for the vehicle under test, significantly reducing production line measurement efficiency and increasing the risk of operational errors. It also fails to meet the demands of modern automotive manufacturing for high-frequency switching and high-precision synchronous measurement. Therefore, a vehicle dimension measuring device capable of high-precision measurement, flexible adjustment, and rapid switching is needed to meet the requirements of measuring the overall dimensions of different vehicle models, as well as efficient switching and measurement.

[0028] To address the aforementioned problems, this application provides a vehicle size measuring device and method, an electronic device, and a storage medium.

[0029] Please see Figures 1 to 9 , Figure 1 This is a first-view overall structural schematic diagram of a vehicle size measuring device provided in an embodiment of this application; Figure 2 This is a second-view overall structural schematic diagram of a vehicle size measuring device provided in an embodiment of this application; Figure 3 This is a schematic diagram of the disassembled structure of a vehicle size measuring device provided in one embodiment of this application; Figure 4 This is a third-view overall structural schematic diagram of a vehicle size measuring device provided in an embodiment of this application; Figure 5 yes Figure 4 An enlarged structural schematic diagram of part A of the provided vehicle dimension measuring device; Figure 6 yes Figure 4 An enlarged structural schematic diagram of part B of the provided vehicle dimension measuring device; Figure 7This is a schematic diagram of the structure of the mounting base for a vehicle size measuring device provided in one embodiment of this application; Figure 8 This is a schematic diagram of the lifting mechanism of a vehicle size measuring device provided in one embodiment of this application; Figure 9 This is a schematic diagram of the structure of the top-mounted part, the first measuring part, and the adjusting mechanism of the vehicle size measuring device provided in an embodiment of this application.

[0030] Please see Figure 1 The vehicle size measuring device 100 provided in this application includes a mounting base 1, a top mounting part 3, and a first measuring part 4. The mounting base 1 includes a base 101 and a support frame 104 mounted on one side of the base 101. The base 101 serves as a support base plate and can be used to support the vehicle to be measured. The top mounting part 3 is disposed on one side of the support frame 104 and is disposed opposite to the base 101. A measuring space 109 for accommodating the vehicle to be measured is formed between the top mounting part 3 and the base 101. The first measuring part 4 is disposed on the side of the top mounting part 3 facing the base 101 and is used to scan the vehicle to be measured and measure a first angle.

[0031] Specifically, the base 101 and support frame 104 in the mounting base 1 constitute the basic load-bearing structure. The base 101 is used to assist in the installation and fixation of other structures of the vehicle size measuring device 100, so as to facilitate the support of the vehicle under test. The base 101 can be a plate-like structure, and its shape and size can be flexibly set as needed, such as a rectangular or polygonal plate. The support frame 104 provides a stable mounting reference for the top mounting part 3. The top mounting part 3 is disposed on the side of the support frame 104 facing the base 101, so that the top mounting part 3 and the base 101 are arranged opposite each other to form a measurement space 109 for accommodating the vehicle under test. The size and shape of the measurement space 109 need to be adapted to the outer contour of the vehicle under test. The first measuring part 4 is integrated into the top mounting part 3. The first measuring part 4 is specifically installed on the side of the top mounting part 3 facing the base 101, so that the vehicle under test in the measurement space 109 can be scanned and a first angle measured. In one embodiment, the first angle can be the angle of the roof of the vehicle under test, or the angle of the roof, front and rear of the vehicle under test. The first measuring unit 4 can specifically be a scanning measuring unit, such as a laser scanner.

[0032] In one embodiment, please refer to Figures 1 to 7The outer wall of the base 101 has two opposing mounting slots 103. A support frame 104 is fixedly connected to the inside of the two mounting slots 103 (e.g., by screws). The support frame 104 assists in the installation of the top mount 3 and the first measuring part 4, facilitating the measurement of the vehicle's dimensions while maintaining stability. Two reinforcing side plates 105 are fixedly connected between the support frame 104 and the base 101. The reinforcing side plates 105 are located on the outer surfaces of the support frame 104 and the base 101, providing support and reinforcement at the connection point, improving the connection stability of the support frame 104 and the stability of the top mount 3 and the first measuring part 4. The reinforcing side plates 105 can be triangular, rectangular, or polygonal, etc. One end of the reinforcing side plate 105 is fixed to the support frame 104 (e.g., by screws), and the other end is fixed to the side of the base 101 (e.g., by screws).

[0033] In one implementation, please refer to Figures 1 to 3 The vehicle size measuring device 100 provided in this application further includes an adjustment mechanism 401, which is connected to the first measuring unit 4. The adjustment mechanism 401 is configured to rotate and drive the first measuring unit 4 to rotate, thereby adjusting the first angle. The first measuring unit 4 includes a scanning assembly 403 and a scanning head 404. The scanning assembly 403 is disposed on the side of the top mount 3 facing the base 101 and is fixedly connected to the adjustment mechanism 401. The scanning head 404 is disposed on the side of the scanning assembly 403 facing the base 101. The adjustment mechanism 401 can be specifically connected to the scanning assembly 403. The scanning assembly 403 is used to cooperate with the scanning head 404 to scan the vehicle under test, thereby further facilitating the scanning and measurement of the vehicle under test.

[0034] For details, please refer to Figures 1 to 9The adjustment mechanism 401 can have two parts, each with a circumferentially distributed locking hole 402. The locking hole 402 is used to lock the adjustment mechanism 401, ensuring the directional stability of the scanning component 403. The adjustment mechanism 401 drives the first measuring unit 4 to rotate synchronously via rotational motion, thereby achieving flexible adjustment of the first angle. In a specific embodiment, the adjustment mechanism 401 may include components such as a drive motor, a transmission gear set, or a manual rotary handle. The drive motor is preferably a stepper motor or a servo motor to provide precise angle control. The transmission component can be a gear meshing structure, a belt drive structure, or a worm gear structure to transmit rotational power to the first measuring unit 4. The scanning head 404 can be a three-dimensional data acquisition device such as a laser scanning head, a structured light camera, or a lidar, used to acquire the dimensional data of the vehicle under test, achieving non-contact, high-precision three-dimensional scanning. During implementation, the adjustment mechanism 401 receives signals from the control system (not shown) of the vehicle size measuring device 100, controlling the motor to rotate at a specific angle according to a preset program. Alternatively, the operator can manually rotate the adjustment mechanism 401 via the external control dial 307, causing the first measuring unit 4 to rotate around a fixed axis. For example, when it is necessary to measure the side profile of the vehicle at different heights, the adjustment mechanism 401 rotates the first measuring unit 4 upwards or downwards; when it is necessary to scan the top or front and rear of the vehicle, the adjustment mechanism 401 rotates the first measuring unit 4 in the horizontal plane. Furthermore, in other embodiments, the adjustment mechanism 401 can also integrate an angle encoder to provide real-time feedback on the current rotation angle of the first measuring unit 4, ensuring the accuracy of the measurement position. Through this rotating connection method, the first measuring unit 4 can overcome the limitations of fixed installation, adapting to differences in body height, width, and profile curvature of different vehicle models, achieving comprehensive three-dimensional scanning coverage without blind spots.

[0035] This embodiment of the application uses a rotatable adjustment mechanism 401 to drive the first measuring unit 4 to adjust its angle. This allows the vehicle size measuring device 100 to adapt to the size variations of different vehicle models in a multi-model mixed-line production environment, eliminating the need for complex mechanical disassembly or recalibration during model changeovers and significantly shortening the switching time of the vehicle size measuring device 100. The rotational adjustment function of the adjustment mechanism 401 allows the first measuring unit 4 to cover different areas of the vehicle under test, such as the sides, top, and front and rear, improving the completeness of the measurement and the comprehensiveness of the data, and avoiding measurement blind spots caused by fixed angles. At the same time, the motor-driven or mechanically locked adjustment method reduces the need for manual intervention, lowers operational errors, and improves the consistency and efficiency of vehicle production line measurements, meeting the requirements of modern automobile manufacturing for high-frequency switching and high-precision synchronous detection.

[0036] In one implementation, please refer to Figures 1 to 7The support frame 104 includes a horizontal part 1041 and two vertical parts 1042 connected to both ends of the horizontal part 1041. The ends of the two vertical parts 1042 facing away from the horizontal part 1041 are connected to the base 101 and are arranged intersecting the base 101. The top mounting part 3 is disposed on the side of the horizontal part 1041 facing the base 101 and can rotate relative to the horizontal part 1041. The adjustment mechanism 401 is disposed on the side of the top mounting part 3 facing the base 101 and facing away from the horizontal part 1041, so as to measure at least the roof of the vehicle under test (in other embodiments, the front and rear of the vehicle under test can also be measured).

[0037] Specifically, the horizontal portion 1041 of the support frame 104 serves as the main load-bearing beam, with both ends fixedly mounted on the base 101 via two vertical portions 1042, thus forming a portal-shaped or inverted U-shaped structure. The two vertical portions 1042 are arranged intersectingly with the base 101, and can further be vertically positioned relative to the base 101. This structure not only provides a stable support foundation but also increases the overall structural stability and optimizes space utilization through spatial intersecting arrangement, enabling the device to adapt to different widths and heights of the vehicle chassis under test. In one specific embodiment, the vertical portions 1042 can be two parallel columns, with the horizontal portion 1041 spanning the tops of the two columns. The base 101 is a flat plate fixed to the ground or production line, and the vertical portions 1042 and the base 101 form a triangular stable structure through reinforcing ribs or diagonal braces. The top mount 3 is positioned on the side of the horizontal part 1041 near the base 101, for example, above or to the side of the vehicle under test. It can rotate relative to the horizontal part 1041, allowing the top mount 3 to adjust its spatial orientation and flexibly position the first measuring part 4 below it to measure different parts of the vehicle. The adjustment mechanism 401 is located on the side of the top mount 3 away from the horizontal part 1041, i.e., towards the base 101. The core function of the adjustment mechanism 401 is to drive or cooperate with the top mount 3 to measure the top area of ​​the vehicle under test, allowing the first measuring part 4 to extend downwards or adjust its angle to accurately capture the contour dimensions of the roof. In one specific embodiment, the horizontal part 1041 can be made of high-strength aluminum alloy profile to reduce weight while ensuring strength, facilitating the installation and maintenance of the overall structure. The two vertical parts 1042 can be fixed to the base 101 by welding or bolting. The two vertical parts 1042 can also be integrally formed with the horizontal part 1041, thereby improving structural stability. The cross-mounted arrangement can take the form of a vertical or inclined rectangular frame structure, which can disperse the potential impact force when the vehicle under test passes by. The rotational connection of the top mount 3 can be achieved through hinges, shafts, or rotary bearings, allowing the top mount 3 to rotate freely within a certain angle range or lock in a specific position. The adjustment mechanism 401 can take the form of an electric push rod, a hydraulic cylinder, or a robotic arm with a locking function, for precisely controlling the position and angle of the measuring components. The adjustment mechanism 401 can also be a torsion frame. For example, when it is necessary to measure the roof of a vehicle under test at different heights, the adjustment mechanism 401 can drive the top mount 3 to rotate, so that the scanning head 404 below is adjusted to the optimal measurement height and angle. In addition, the top mount 3 can also integrate a mounting block for fixing the scanning head 404, which is detachably connected to the main body of the top mount 3 for quick replacement of different types of scanning sensors. In another embodiment, the rotation of the top mount 3 can be a continuous stepless adjustment or a step-by-step angle adjustment, depending on the production line's requirements for changeover speed.The adjustment mechanism 401 may also include a position feedback sensor, such as an encoder, to monitor the rotation angle of the top mount 3 in real time, ensuring the accuracy and repeatability of the measurement data.

[0038] By employing a support frame 104 structure consisting of a horizontal section 1041 and two vertical sections 1042, the overall rigidity and stability of the vehicle dimension measuring device 100 can be effectively improved. Especially in multi-model mixed-line production environments, it can resist vibrations and airflow interference generated when the vehicle under test passes by, ensuring the accuracy of the measurement data. The top mount 3 is located on the side of the horizontal section 1041 facing the base 101 and has a rotation function, allowing the vehicle dimension measuring device 100 to flexibly adjust the spatial position of the scanning component 403. It can adapt to the roof height and contour features of different vehicle models without large-scale hardware reinstallation, greatly shortening the vehicle changeover time. The adjustment mechanism 401 is located on the side of the top mount 3 away from the horizontal section 1041 and facing the base 101, allowing the measuring component to directly act on the top of the vehicle under test, achieving omnidirectional scanning without blind spots. Especially for the critical dimension area of ​​the roof, it can acquire high-precision three-dimensional data. This structural design avoids the cumbersome process of manual recalibration and mechanical adjustment required when changing models of traditional fixed measuring devices, achieving flexible adaptation of the physical structure and thus significantly improving the measurement efficiency and consistency of the production line. Furthermore, the two vertical sections 1042 intersecting the base 101 not only enhance support stability but also optimize the internal space layout, providing ample installation space for the adjustment mechanism 401 and transmission components, making the overall structure more compact and rational. Through the rotational connection and the cooperation of the adjustment mechanism 401, the control system can automatically or semi-automatically adjust the measurement angle and position, reducing operational errors and improving the automation and intelligence level of the inspection process, meeting the needs of modern automobile manufacturing for high-frequency switching and high-precision synchronous inspection.

[0039] In one embodiment, please refer to Figures 1 to 7 The top mounting part 3 includes a fixing plate 301. A mating slot 108 is provided at the middle of the top of the support frame 104 (i.e., the middle of the horizontal part 1041). The mating slot 108 can be a rectangular through hole. The mating slot 108 can be used to install the top mounting part 3 and the adjustment mechanism 401, for example, by means of snap-fit ​​or screw connection. The mating slot 108 can also assist in the installation of the fixing plate 301 to facilitate the stability of the horizontal part 1041. The fixing plate 301 is a cuboid structure that matches the shape of the mating slot 108. The fixing plate 301 is inserted inside the mating slot 108, allowing it to cover the mating slot 108 from the outside, thereby improving the stability and aesthetics of the support frame 104.

[0040] Furthermore, two docking slots 302 are provided on the outer wall of the fixed insert plate 301, and a bottom mounting bracket 303 is fixedly connected to the bottom of the fixed insert plate 301. The two docking slots 302 are respectively set as circular through holes. A rectangular groove for docking with the fixed insert plate 301 is provided on the top of the bottom mounting bracket 303. A rotating shaft (not shown in the figure) is fixedly connected to the end of the bottom mounting bracket 303. A disc structure 309 is fixedly connected to the two rotating shafts of the bottom mounting bracket 303. The bottom mounting bracket 303 has internal adjustment grooves 304 at both ends. The two circular disc structures 309 of the bottom mounting bracket 303 each have circumferentially distributed internal grooves 305. Each internal adjustment groove 304 and each internal groove 305 has a circular through hole. The two internal adjustment grooves 304 are slidably connected to the outer pull brackets 306. Each of the two outer pull brackets 306 has a spring 310. Locking rods 308 are slidably connected to the corresponding internal grooves 305. External control plates 307 are fixedly connected to the locking rods of the two outer pull brackets 306, and locking rods 308 are fixedly connected to the two external control plates 307. The external control plates 307 control the insertion or disengagement of the locking rods 308 into the locking holes 402, thereby adjusting the angle of the scanning head 404. The locking rod 308 and the locking hole 402 can be fitted with a tapered mating surface to increase the locking force; the spring 310 can be a compression coil spring to provide the restoring force. When it is necessary to lock the scanning angle, pulling the external control lever 307 retracts the locking rod 308. After releasing, the spring 310 drives the locking rod 308 to automatically insert into the locking hole 402, achieving mechanical locking. In a mixed-line production environment, when the vehicle model is switched, the control system identifies the vehicle model information of the vehicle to be tested, automatically adjusts the lifting mechanism 2 to adjust the height of the second measuring unit 207, and adjusts the angle of the first measuring unit 4 accordingly, without the need for manual mechanical adjustment, thus achieving rapid adaptation to different vehicle models.

[0041] The adjustment mechanism 401 is connected to the top mounting part 3 via the bottom mounting bracket 303. For example, two adjustment mechanisms 401 are rotatably connected to the rotating shaft of the bottom mounting bracket 303 respectively. The locking socket 402 can be aligned with the corresponding built-in groove 305. A corresponding locking rod 308 can be inserted into the locking socket 402. The scanning component 403 can be electrically connected to the control system. A scanning head 404 is provided at the bottom of the scanning component 403. The scanning head 404 is used to scan and measure the vehicle under test.

[0042] In one implementation, please refer to Figures 1 to 8The vehicle size measuring device 100 also includes a second measuring unit 207, which is used to perform a second angle measurement on the vehicle under test. This second angle is different from the first angle. For example, the second angle can be the angle measuring the side of the vehicle under test, or it can be the angle measuring the side, front, and rear of the vehicle under test. It is understood that either the second angle or the first angle is used to measure the front and rear of the vehicle to reduce the operating power consumption and cost of the vehicle size measuring device 100; or both the second angle and the first angle are used to measure the vehicle under test to facilitate data verification through multiple measurements and improve measurement accuracy. The specific selection and setting can be flexibly determined based on the vehicle model under test. For example, the first measuring unit 4 measures the top, front, and rear of the vehicle under test, while the second measuring unit 207 measures the side of the vehicle under test; or the first measuring unit 4 measures the top of the vehicle under test, while the second measuring unit 207 measures the side, front, and rear of the vehicle under test.

[0043] Specifically, the second measuring unit 207 is used to measure the second angle of the vehicle under test, meaning the vehicle size measuring device 100 has multi-view data acquisition capabilities. The first angle typically refers to the angle data (e.g., the roof) acquired by the main scanning component 403 (such as the scanning head 404 mounted on the adjustment mechanism 401) at a specific initial position or main scanning path. The second angle can correspond to the scanning component 403 rotating to another position, or to data acquired by an independent auxiliary sensor (such as the second measuring unit 207) at an orientation different from the first angle. In terms of implementation, when the second angle corresponds to the scanning component 403 rotating to another position, the second measuring unit 207 can be integrated into the adjustment mechanism 401 of the first measuring unit 4, and the adjustment mechanism 401 connected to the bottom mounting bracket 303 can be rotated to the second preset angle for scanning; or, the second measuring unit 207 can be an additional sensor module independent of the scanning component 403, fixedly mounted on the support bracket 104, to scan the vehicle under test from different spatial orientations such as the side, bottom, or top. In one specific embodiment, a horizontally rotating structured light camera or lidar can be set as the first measuring unit 4, while a vertically fixed laser profilometer can be set as the second measuring unit 207. Both cover different contour areas of the vehicle under test. For example, the first measuring unit 4 measures the top, front, and rear of the vehicle, while the second measuring unit 207 measures the sides; or the first measuring unit 4 measures the top of the vehicle, while the second measuring unit 207 measures the sides, front, and rear. This multi-angle measuring layout, combined with data integration and calculation by the control system, can eliminate blind spots in single-view measurements, improving measurement accuracy and efficiency.

[0044] By introducing a second measuring unit 207 and cooperating with the first measuring unit 4 to perform multi-angle measurements, a complete, blind-spot-free coverage of the entire outline of the vehicle under test can be achieved. This is particularly beneficial for complex geometric areas such as the sides of the vehicle body, wheel arches, and bumpers, where a single angle often results in obstruction or measurement blind spots. The introduction of the second angle allows the device to capture detailed data from the back or sides that cannot be directly observed from the first angle, thereby significantly improving the completeness and accuracy of the overall vehicle dimension measurement. Through this multi-source data fusion processing, not only are dimension estimation errors caused by missing viewpoints reduced, but the reliability of measurement results is also improved through cross-verification of data from different angles. This meets the demand for high-precision, rapid-switching dimension inspection in multi-model mixed-line production, effectively reducing the quality control risks caused by incomplete measurements.

[0045] In one implementation, please refer to Figures 1 to 7 The support frame 104 includes a horizontal part 1041 and vertical parts 1042 connected to both ends of the horizontal part 1041. One end of the two vertical parts 1042 away from the horizontal part 1041 is connected to the base 101 and is arranged to cross the base 101. The second measuring part 207 is provided on one side of the vertical part 1042 to measure at least the side of the vehicle to be measured.

[0046] Specifically, the support frame 104 is the basic structural component used to support and fix the measurement module; its specific structure is described above and will not be repeated here. The second measurement unit 207 is configured as a laser emitter or a similar 3D scanning sensor, fixedly mounted on the inner side of the vertical unit 1042, with its detection direction facing the side of the vehicle under test. During implementation, the vertical unit 1042 can be fixed to the base 101 by bolts, welding, or clips, for example, using an L-shaped or T-shaped metal bracket made of high-strength aluminum alloy or steel. The second measurement unit 207 can be directly fixed to the vertical unit 1042 via a bracket, or connected to the vertical unit 1042 via an adjustable robotic arm for fine-tuning of the measurement angle. In one specific embodiment, the vertical part 1042 can be two parallel columns, the horizontal part 1041 spans the top of the two columns, and the base 101 is a flat plate fixed to the ground or production line. The vertical part 1042 and the base 101 form a triangular stable structure through reinforcing ribs or diagonal braces. The second measuring part 207 is installed on the outside of the columns. The second measuring part 207 (e.g., a laser emitter) measures the side of the vehicle to be tested.

[0047] By employing a frame structure consisting of a horizontal section 1041 and two vertical sections 1042, and combining this with the cross-arrangement with the base 101, the overall rigidity and vibration resistance of the support frame 104 are significantly enhanced. This ensures that the support frame 104 is less prone to deformation or swaying when bearing the weight of the second measuring section 207 and the dynamic load during operation, thus guaranteeing the stability of the measurement reference. The second measuring section 207 is located on one side of the vertical section 1042, allowing the measurement optical path to directly cover the side profile of the vehicle under test, avoiding obstruction from other structural components, and achieving a blind-spot-free measurement of the side of the vehicle under test.

[0048] In one implementation, please refer to Figures 1 to 4 , Figure 6 and Figure 8 The vehicle size measuring device 100 includes a lifting mechanism 2, which includes a rotating rod 203. The rotating rod 203 is arranged parallel to the vertical part 1042 and is configured to rotate. A displacement block 205 is rotatably connected to the rotating rod 203. A sliding arm 204 is provided on the displacement block 205 and is slidably connected to the vertical part 1042. The rotating rod 203 drives the displacement block 205 to rotate and move, and drives the sliding arm 204 to move up and down along the vertical part 1042. A second measuring part 207 is provided on the side of the displacement block 205 away from the vertical part 1042 to perform measurement during or after the displacement block 205 moves up and down.

[0049] Specifically, there can be two lifting mechanisms 2, one-to-one corresponding to one side of the two vertical parts 1042, or one-to-one connected to the two vertical parts 1042. The lifting mechanism 2 drives the rotating rod 203 to rotate through the first driving member 202, which drives the second measuring part 207 to rise and fall in the vertical direction, thereby covering the side profile of vehicles of different heights. The rotating rod 203 is parallel to the vertical part 1042 and can rotate. For example, the rotating rod 203 can be a screw, and the rotation of the rotating rod 203 drives the displacement block 205 connected to the rotating rod 203 to produce vertical displacement. For example, the rotating rod 203 is a rod-shaped structure set inside the vertical part 1042 and parallel to the vertical part 1042. In this case, one end of the rotating rod 203 is connected to the horizontal part 1041, and the other end is connected to the base 101. The rotating rod 203 can be connected to the horizontal part 1041 and the base 101 by means of plug-in, snap-fit, threaded connection or screw connection. For example, a groove is provided in the horizontal part 1041 to house the plug 208, and one end of the rotating rod 203 is inserted into the plug 208 for connection. The displacement block 205 is rotatably connected to the rotating rod 203. For example, a servo motor or stepper motor can be used to drive the rotating rod 203 to rotate, or a pneumatic or hydraulic cylinder can be used to directly push the displacement block 205 up and down. In this case, the rotating rod 203 may exist as an angle adjustment or auxiliary locking mechanism. Alternatively, a lead screw and nut pair structure can be used to directly convert the rotational motion into linear motion. In this case, the rotating rod 203 can be understood as part of the lead screw or a component that drives the lead screw to rotate. The displacement block 205 is provided with a sliding arm 204, which is slidably connected to the vertical part 1042. This structure forms a typical crank-slider or connecting rod transmission mechanism, converting the rotational motion of the rotating rod 203 into the linear up and down motion of the displacement block 205 along the vertical part 1042.

[0050] For example, in one embodiment, the vertical part 1042 may have a groove (not shown), and the sliding arm 204 acts as a sliding block to slide up and down along the groove; there may be two sliding arms 204, which are respectively arranged on both sides of the displacement block 205, and the two sliding arms 204 slide up and down along the groove.

[0051] In another embodiment, please refer to Figures 1 to 9Alternatively, a separate sliding rod 201 can be slidably connected to the sliding arm 204. For example, the sliding rod 201 is used to help maintain the stability of the sliding arm 204 during the adjustment process of the adjustment mechanism 401, so as to facilitate the adjustment mechanism 401 to perform position adjustment. Sliding arms 204 are slidably connected to the sliding rods 201 of the two lifting mechanisms 2. The sliding arms 204 are used to fix the second measuring part 207 in conjunction with the displacement block 205, and to adjust its position under the action of the rotating rod 203, so as to facilitate the adjustment of the detection position of the vehicle size to be tested. The displacement block 205 is fixed between the two sliding arms 204. The displacement block 205 is used to adjust its position under the drive of the rotating rod 203, so as to facilitate the control of the second measuring part 207 and the adjustment of the detection position of the vehicle size to be tested. A mounting plate 206 is fixed to the displacement block 205. The mounting plate 206 is used to assist in the installation of the second measuring part 207 so as to keep it stable. The second measuring part 207 is fixed to the mounting plate 206, and the second measuring part 207 is used to scan and detect the vehicle to be tested. The second measuring unit 207 is fixed on the side of the displacement block 205 away from the vertical part 1042. Its height position changes as the displacement block 205 rises and falls, thereby realizing the scanning measurement of the parts of the vehicle to be measured at different heights.

[0052] In a further embodiment, the top of the support frame 104 may have two docking holes 106, each of which is a circular through hole. The docking holes 106 are used to assist in docking with the plug 208 to facilitate the stability of the rotating rod 203. The top of the support frame 104 is fixed with two locking blocks 107. The locking blocks 107 are used to assist in maintaining the stability of the fixed plug plate 301 by inserting them into the docking slot 302, so as to facilitate its use. A docking slot 108 is provided at the middle of the top of the support frame 104. The docking slot 108 is a rectangular through hole. The docking slot 108 is used to assist in the installation of the fixed plug plate 301 to facilitate its stability.

[0053] Two sliding rods 201 are fixedly connected to the outer wall of the support frame 104. The two sliding rods 201 are respectively set as cylindrical rod structures. A first driving member 202 is provided on the outer side of the two sliding rods 201. The first driving member 202 is fixedly connected in the corresponding mating mounting groove 103. The first driving member 202 is used to drive the rotating rod 203 to rotate and adjust its position. During the rotation, the sliding arm 204 and the displacement block 205 are adjusted through the thread to adjust the measuring height of the second measuring part 207. The motor shaft of the first driving member 202 is connected to the rotating rod 203. The rotating rod 203 is set as a threaded rod structure. Circular through holes are opened on the two sliding arms 204 for cooperating with the corresponding sliding rods 201.

[0054] The displacement block 205 is configured as a rectangular block structure, and a threaded through hole for cooperating with the rotating rod 203 is opened in the middle position of the displacement block 205. The mounting plate 206 is configured as a square plate structure. The second measuring part 207 is electrically connected to the control system. The top end of the rotating rod 203 is fixedly connected to the plug 208, which is inserted into the corresponding mating hole 106. The plug 208 is configured as a cylindrical structure. The plug 208 is used to keep the rotating rod 203 stable during adjustment by inserting it into the mating hole 106, which facilitates the position adjustment of the sliding arm 204 and the displacement block 205.

[0055] The second measuring unit 207 can specifically employ 3D scanning sensors such as laser profilometers, structured light cameras, or lidar to acquire dimensional data of the side profile of the vehicle under test. During implementation, when adapting to different vehicle models, the control system retrieves the corresponding height parameters from the vehicle model database, driving the rotating rod 203 to rotate by a specific angle. This causes the displacement block 205 and sliding arm 204 to rise along the vertical section 1042 to the target height. At this point, the second measuring unit 207 is in the predetermined measuring position and begins scanning a specific height layer of the side profile of the vehicle under test. The design of the rotating rod 203 driving the displacement block 205 and sliding arm 204 enables stepless adjustment of the measurement height, eliminating the need for manual disassembly or reinstallation of the sensors and significantly reducing preparation time when switching between different vehicle models. The sliding cooperation between the sliding arm 204 and the vertical section 1042 ensures the stability and straightness of the lifting process, avoiding measurement errors caused by swaying. The second measuring unit 207 rises and falls synchronously with the displacement block 205, enabling continuous or segmented scanning across the entire vehicle height range, ensuring complete acquisition of the side profile data of the vehicle under test. This structure simplifies the lifting drive system, improves the reliability and ease of maintenance of the vehicle size measuring device 100, and is particularly suitable for the needs of rapid model switching and efficient measurement in multi-model mixed production environments.

[0056] In one implementation, please refer to Figures 1 to 8 There are two second measuring units 207, which are respectively set in two vertical parts 1042.

[0057] Specifically, the second measuring unit 207 refers to a sensor assembly used to perform side or front / rear dimension detection of the vehicle under test. The two vertical parts 1042 are structural components in the mounting base 1 or lifting mechanism 2 used for vertical support and guidance, such as columns or guide rail frames. Two second measuring units 207 are provided and installed one-to-one on the two vertical parts 1042, meaning an independent measuring unit is deployed on each of the left and right sides of the vehicle under test. The second measuring units 207 can be fixed to predetermined positions on the vertical parts 1042 by mechanical bolts, welding, or snap-fit ​​connections to ensure spatial stability during the measurement process. In one specific embodiment, the second measuring unit 207 on the left can be installed inside the left vertical part 1042, and the second measuring unit 207 on the right can be installed inside the right vertical part 1042, with them arranged opposite each other to cover the entire side profile of the vehicle under test. Furthermore, the second measuring unit 207 can also have a fine angle adjustment function, using a micro servo motor or a manual fine-tuning knob to maintain the optimal working distance and angle between its emitting surface or photosensitive surface and the side of the vehicle under test, thereby optimizing data acquisition quality. The angles of the two second measuring units 207 can also be finely adjusted to measure the dimensions of the front and rear of the vehicle under test.

[0058] By employing two second measuring units 207, each positioned on one of two vertical sections 1042, simultaneous or coordinated measurement of the left and right sides of the vehicle under test can be achieved. This symmetrical layout eliminates the problems of viewpoint obstruction or data loss that may occur due to single-sided measurement, ensuring the acquisition of complete three-dimensional side data. When both measuring units operate simultaneously, measurement efficiency can be significantly improved, and scanning time can be reduced, thus adapting to the needs of rapid switching and high-efficiency inspection in multi-model mixed-line production. Simultaneously, the configuration of two second measuring units 207 provides data redundancy; if one sensor experiences a brief malfunction or data anomaly, the control system can compensate using data or algorithms from the other side, improving the reliability and consistency of the measurement. Furthermore, this modular, one-to-one installation method simplifies the maintenance and replacement of individual measuring units, eliminating the need for large-scale adjustments to the entire vehicle dimension measuring device 100, further reducing production line downtime and maintenance costs.

[0059] In one implementation, please refer to Figures 1 to 4 , Figure 7 The vehicle size measuring device 100 also includes a control system and a weighing component 102. The control system is electrically connected to the first measuring unit 4, the second measuring unit 207, the adjusting mechanism 401 and the lifting mechanism 2, and is used to receive measurement data and obtain the overall vehicle size parameters of the vehicle to be measured. The weighing component 102 is disposed on the base 101 and is electrically connected to the control system. The weighing component 102 is used to obtain the weight data of the vehicle to be measured.

[0060] In one embodiment, the control system acts as an external data processing and control center, electrically connected to the first measuring unit 4, the second measuring unit 207, and the drive motor via wired or wireless communication. The control system receives measurement data from the second measuring unit 207 and the first measuring unit 4, and uses a built-in algorithm module (not shown) to perform data stitching, filtering, and feature extraction to ultimately calculate the overall vehicle dimensions, including length, width, height, wheelbase, and track width. The control system is electrically connected to the adjustment mechanism 401 and the lifting mechanism 2, allowing the adjustment mechanism 401 to adjust to a first angle to facilitate measurements by the first measuring unit 4 at different angles. Additionally, the control system can control the lifting mechanism 2 to perform lifting movements, enabling the second measuring unit 207 to measure data at different heights of the vehicle under test.

[0061] Specifically, a mounting groove (not shown) can be formed on the surface of the base 101 facing the horizontal part 1041. The weighing component 102 is embedded in the mounting groove. The weighing component 102 can be composed of multiple pressure sensors or weighing modules distributed at the four corners of the base 101. These sensors collect the pressure distribution of the vehicle under test on the base 101 in real time and convert the analog signals into digital signals, which are then transmitted to the control system. The control system calculates the total weight of the vehicle under test based on the pressure data and the gravitational acceleration constant. The layout of the weighing component 102 can be symmetrical to balance the force, or it can be circular to adapt to the wheel positions of different vehicle models. For example, independent weighing units can be set at the four corners of the base 101, and the stability and accuracy of weighing can be improved by using a weighted average algorithm.

[0062] By integrating the measuring device and weighing component 102, simultaneous dimensional measurement and weight detection are achieved. The control system automatically integrates measurement data from different sensors (first measuring unit 4 and second measuring unit 207), eliminating the time delays and data asynchrony problems caused by traditional manual recording and independent operation of multiple devices, thus significantly improving detection efficiency. The weighing component 102 is integrated into the vehicle dimensional measuring device 100, simplifying the layout of on-site equipment and eliminating the need for an additional independent weighing platform, saving workshop space. This synchronous acquisition mechanism allows the production line to simultaneously obtain the two key quality indicators of size and weight during the passage of a vehicle under test, reducing the dwell time of the vehicle under test and improving production line efficiency. In addition, the data integration capability of the control system provides a complete dataset for subsequent quality analysis, facilitating the tracing and analysis of the correlation between size and weight. For example, weight data can be used to help determine whether body parts are missing or misaligned, thereby improving the overall quality control level.

[0063] To address the aforementioned issues, this application also provides a method for measuring vehicle dimensions.

[0064] Please see Figure 10 and Figure 11 , Figure 10 This is a schematic flowchart of the overall process of a vehicle size measurement method provided in an embodiment of this application; Figure 11 yes Figure 10 The flowchart of the sub-steps of step S3 is provided.

[0065] Please see Figure 10 The vehicle size measurement method provided in one embodiment of this application is applicable to the vehicle size measurement device 100 described above, and the measurement method may include the following steps: S1: Obtain information about the vehicle under test and obtain the corresponding measurement program based on the information about the vehicle under test.

[0066] Specifically, obtaining information about the vehicle under test means identifying the vehicle model by reading the VIN (Vehicle Identification Number) or RFID (Radio Frequency Identification) tag of the vehicle under test. The control system automatically calls the pre-stored measurement program for the corresponding vehicle model, such as loading different scanning path parameters for vehicles with different wheelbases or body heights.

[0067] S2: Measure the vehicle under test according to the measurement program corresponding to the vehicle under test.

[0068] Specifically, the control system performs dimensional measurements according to the measurement program corresponding to the vehicle under test. For example, the length, width, height, and shape of each vehicle under test are different. A specific measurement program for each vehicle under test can be preset in the control system. After detecting that the vehicle under test is the preset model, the preset measurement program can be directly retrieved for measurement, thereby improving measurement accuracy and efficiency.

[0069] S3: Drive the first measuring unit 4 to scan the vehicle under test and measure the first angle.

[0070] Specifically, the first measuring unit 4 is disposed on the side of the top-mounted part 3 facing the base 101, and is used to scan the vehicle under test and measure a first angle. The first angle can be the angle of the roof of the vehicle under test, or the angle of the roof, front and rear of the vehicle under test. The first measuring unit 4 can be a scanning measuring unit, such as a laser scanner.

[0071] For further details, please refer to Figure 11 Step S3, which drives the first measuring unit 4 to scan the vehicle under test and measure the first angle, may include: S31: Drive the adjustment mechanism 401 to rotate, and drive the first measuring part 4 to rotate through the adjustment mechanism 401 to adjust the first angle.

[0072] Specifically, the adjustment mechanism 401 is connected to the first measuring unit 4. The adjustment mechanism 401 drives the first measuring unit 4 to rotate synchronously through rotational motion, thereby achieving flexible adjustment of the first angle. The adjustment mechanism 401 receives signals from the control system and controls the motor to rotate a specific angle according to a preset program, driving the first measuring unit 4 to rotate around a fixed axis. For example, when it is necessary to measure the side profile of the vehicle under test at different heights, the adjustment mechanism 401 drives the first measuring unit 4 to rotate upward or downward; when it is necessary to scan the top or front and rear of the vehicle under test, the adjustment mechanism 401 drives the first measuring unit 4 to rotate in the horizontal plane.

[0073] S32: Scan and measure the vehicle under test based on the first angle.

[0074] Specifically, the first measuring unit 4 is rotated to the required first angle by the adjusting mechanism 401 in order to scan and measure the vehicle under test.

[0075] S4: Drive the second measuring unit 207 to perform a second angle measurement on the vehicle under test; wherein the second angle is different from the first angle.

[0076] Specifically, the second measuring unit 207 can be an additional sensor module independent of the first measuring unit 4, fixedly mounted on the base 101 or support frame 104, scanning the vehicle under test from different spatial orientations such as the side, bottom, or top. The second measuring unit 207 can specifically be a laser profilometer. The second angle can be the angle measuring the side of the vehicle under test, or it can be the angle measuring the side, front, and rear of the vehicle under test. By introducing the second measuring unit 207 and cooperating with the first angle of the first measuring unit 4 to perform multi-angle measurements, it is possible to achieve full contour coverage of the vehicle under test without blind spots, eliminating measurement blind spots under a single viewpoint, and improving measurement accuracy and efficiency.

[0077] Furthermore, step S4, which drives the second measuring unit 207 to perform a second angle measurement on the vehicle under test, may include: driving the second measuring unit 207 to perform a lifting motion by driving the lifting mechanism 2, so that the second measuring unit 207 performs a second angle measurement; wherein the second measuring unit 207 is connected to the lifting mechanism 2.

[0078] Specifically, the lifting mechanism 2 includes a rotating rod 203, which is arranged parallel to the vertical part 1042. The rotating rod 203 is configured to rotate under the drive of the first driving member 202. The displacement block 205 is rotatably connected to the rotating rod 203. The displacement block 205 is provided with a sliding arm 204, which is slidably connected to the vertical part 1042. The rotating rod 203 drives the displacement block 205 to rotate and move, and drives the sliding arm 204 to move up and down along the vertical part 1042. The second measuring part 207 is provided on the side of the displacement block 205 away from the vertical part 1042, so as to perform measurement during or after the lifting and lowering movement of the displacement block 205.

[0079] S5: Based on the first angle measurement data and the second angle measurement data, obtain the overall vehicle size parameters of the vehicle under test.

[0080] Specifically, the control system receives measurement data from the second measurement unit 207 and measurement data from the first measurement unit 4, and performs data splicing, filtering and feature extraction through the built-in algorithm module to finally calculate the overall vehicle size parameters such as length, width, height, wheelbase and track width of the vehicle under test.

[0081] Please see Figure 12 , Figure 12 This is a schematic flowchart of the overall process of a vehicle size measurement method provided in another embodiment of this application.

[0082] Another embodiment of the vehicle size measurement method provided in this application may further include the following steps: S6: Obtain the weight data of the vehicle under test through the weighing component 102 and transmit the weight data to the control system.

[0083] Specifically, a mounting groove (not shown) can be formed on the surface of the base 101 facing the horizontal part 1041. The weighing component 102 can be embedded in the mounting groove formed on the surface of the base 101 facing the horizontal part 1041. The weighing component 102 can be composed of multiple pressure sensors or weighing modules distributed at the four corners of the base 101. These sensors collect the pressure distribution of the vehicle under test on the base 101 in real time and convert the analog signal into a digital signal and transmit it to the control system. The control system calculates the total weight of the vehicle under test based on the pressure data and the gravitational acceleration constant. By introducing the integrated design of the measuring device and the weighing component 102, the synchronous measurement of dimensions and weight detection is realized. The control system can automatically integrate the measurement data from different sensors (first measuring unit 4 and second measuring unit 207), eliminating the time delay and data asynchronization problems caused by traditional manual recording and independent operation of multiple devices, thereby significantly improving the detection efficiency. The weighing component 102 is integrated into the vehicle dimension measuring device 100, simplifying the layout of the field equipment, eliminating the need for an additional independent weighing platform, and saving workshop space. This synchronous acquisition mechanism enables the production line to obtain two key quality indicators, size and weight, simultaneously during the passage of a vehicle under test, reducing the dwell time of the vehicle under test and improving production line efficiency.

[0084] The specific process of the vehicle size measurement method provided in the above embodiments of this application can be as follows: After the vehicle size measuring device 100 is assembled, if it is necessary to adjust the initial scanning angle of the scanning head 404, pull the outer control lever 307 outward to drive the outer pull bracket 306 to slide along the inner adjustment groove 304, so that the locking rod 308 is pulled out from the locking hole 402 of the adjustment mechanism 401 and retracted into the inner groove 305 to release the constraint on the adjustment mechanism 401. Then, rotate the adjustment mechanism 401 to the required angle, release the outer control lever 307, and the outer pull bracket 306 is reset under the action of the spring 310. The locking rod 308 is reinserted into the corresponding locking hole 402 to complete the scanning direction locking.

[0085] The vehicle under test is slowly driven into the measuring space 109 formed between the top mount 3 and the base 101, ensuring that the vehicle body is centered and the tires or chassis are placed stably on the base 101. The weighing component 102 automatically senses the pressure of the vehicle under test and transmits the weight data to the control system in real time. The control system records and displays the weight information of the vehicle under test. Then, the first drive component 202 is activated by the control system. The first drive component 202 drives the rotating rod 203 to rotate, so that the displacement block 205 drives the sliding arm 204 to slide up and down along the sliding rod 201 under the threaded transmission of the rotating rod 203, thereby adjusting the height of the second measuring part 207. The second measuring part 207 emits laser during the lifting process to scan the height, width and other dimensions of the side of the vehicle under test. The scan data is transmitted to the control system in real time to form the side dimension parameters. Then, the scanning component 403 of the first measuring unit 4 is activated, and the scanning head 404 performs a three-dimensional scan of the top, front, and rear of the vehicle under test. The scanned data is transmitted to the control system and integrated with the side data of the second measuring unit 207 to calculate the complete dimensional parameters of the vehicle under test, such as length, wheelbase, and top profile, thereby completing the dimensional measurement of the vehicle under test.
