[0003] The existing measuring brackets are simple, integrated measuring brackets that can only measure the same platform vehicle model. When measuring other platform vehicle models, manual switching is required, and after switching, calibration requires manual adjustment of shims, which affects working hours and reduces measurement efficiency. In addition, the prototype workshop involves the production of multiple platform vehicle models. Due to the decomposition of early vehicle assembly and matching issues, three-coordinate measurement is required for the corresponding vehicle models. However, since the prototype workshop does not have corresponding platform measuring brackets and measuring equipment, vehicles need to be arranged for transportation, which increases transportation costs and measurement complexity.

[0049] Figure 1 This diagram shows a side view of a multi-vehicle model measuring bracket provided in an embodiment of the present invention; it is applied to the measurement of vehicle structures in three dimensions, and the vehicle structure may include the body structure and other vehicle structures; the three dimensions include a first direction, a second direction, and a third direction; the first direction, the second direction, and the third direction are perpendicular to each other; please refer to... Figure 1 The first direction is the x-direction, the second direction is the y-direction, and the third direction is the z-direction. A multi-vehicle model measuring bracket may include:

[0050] The sliding assembly 100 includes a first sliding structure 110, a second sliding structure 120, and a lifting structure 130 stacked on the third side.

[0051] A support column 200, the bottom end of which is connected to the first sliding structure 110, and a connecting guide rail 210 is provided on one side surface of the support column 200 in the first direction.

[0052] The connecting plate 300 includes a first connecting portion 310 extending along the first direction and a second connecting portion 320 extending along the third direction; the second connecting portion 320 is slidably connected to at least a portion of the support column 200 through a connecting slider 330 in cooperation with the connecting guide rail 210.

[0053] Positioning component 400, which is connected to the first connecting part 310;

[0054] The first sliding structure 110 moves along the first direction, the second sliding structure 120 moves along the second direction, and the lifting structure 130 moves along the third direction, so that the multi-vehicle model measuring bracket 1 moves to the target measuring position, and the multi-vehicle model measuring bracket 1 is fixed at the target measuring position by the positioning component 400 in cooperation with the connecting plate 300.

[0055] Figure 2 This shows a structural side view of the sliding component provided in an embodiment of the present invention, such as... Figure 2 As shown, the sliding assembly 100 may include a first sliding structure 110, a second sliding structure 120, and a lifting structure 130. The number of the first sliding structures 110 is at least one; and the number of the second sliding structures 120 is at least one.

[0056] The first sliding structure 110 includes a first guide rail 111 and a first slider 112, the first slider 112 being slidably engaged with the first guide rail 111 along the first direction; the second sliding structure 120 includes a second guide rail 121 and a second slider 122, the second slider 122 being slidably engaged with the second guide rail 121 along the second direction; and,

[0057] The lifting structure 130 includes a first lifting plane 131, a second lifting plane 132, and a telescopic support portion; the first lifting plane 131 and / or the second lifting plane 132 are vertically coupled to the telescopic support portion along the third direction.

[0058] In one specific embodiment, the sliding component 100 can move in a first direction through multiple first sliding structures 110, move in a second direction through multiple second sliding structures 120, and move to the target measurement position in a third direction through a lifting structure 130. This enables the multi-vehicle measuring bracket 1 to match different vehicle models and measure their various dimensions. The target measurement position can be preset according to different vehicle models and different structures to be tested.

[0059] For the lifting structure 130, such as Figure 1 and / or Figure 2 As shown, it may include a first lifting plane 131 and a second lifting plane 132, and a telescopic support is disposed between the first lifting plane 131 and the second lifting plane 132, so that different positions can be adjusted by lifting the first lifting plane 131.

[0060] By sliding the first slider 112 on the first guide rail 111, the sliding component 100 of the multi-vehicle measuring bracket 1 has a first measuring range of a certain length in the first direction, which can be greater than or equal to the length of the first guide rail 111. By sliding the second slider 122 on the second guide rail 121, the sliding component 100 of the multi-vehicle measuring bracket 1 has a second measuring range of a certain length in the second direction, which can be greater than or equal to the length of the second guide rail 121. Furthermore, by extending and retracting the telescopic support (not shown in the figure) in a third direction, the sliding mechanism of the multi-vehicle measuring bracket 1 has a third measuring range of a certain length in the third direction, which can be equal to the length of the telescopic support when fully extended. The dimensions of the first guide rail 111, the second guide rail 121, and the lengths of the telescopic support when extended and retracted can be set according to specific requirements.

[0061] For the telescopic support section, its length when retracted can be set to be infinitely close to 0, thereby reducing the overall size of the multi-vehicle measuring bracket 1 in the third direction. The number and position of the telescopic support sections can be set according to their cross-sectional area and specific application requirements. For example, the larger the cross-sectional area, the fewer telescopic support sections are required, and the closer the position of the telescopic support sections should be to the center of the first lifting plane 131 and the second lifting plane 132. The smaller the cross-sectional area, the more telescopic support sections are required, and their positions can be evenly distributed towards the edges of the first lifting plane 131 and the second lifting plane 132, thereby improving the stability of the first lifting plane 131 and / or the second lifting plane 132 during the lifting process. For the material of the telescopic support section, a structure with rebound capability, such as a spring, can be selected, or multiple segmented structures can be selected.

[0062] In addition, since the sliding assembly 100 is configured as an electric structure, it can also house at least a control unit and a drive motor.

[0063] The control unit is located inside the sliding assembly 100 and is electrically connected to the control system; the control unit is used to receive drive control commands and provide bracket positioning information and motor drive commands.

[0064] A drive motor is disposed inside the sliding assembly 100; the drive motor is used to receive the motor drive command and the bracket positioning information, and drive the sliding assembly 100 to move in the three-dimensional direction.

[0065] In one specific embodiment, the control unit is electrically connected to the control system and receives drive control commands from the control system to realize information transmission and control the displacement of the multi-model measuring bracket 1. The drive motor is electrically connected to the control unit, thereby responding to the motor drive commands issued by the control unit to drive the sliding component 100 to the position corresponding to the bracket positioning information, wherein the bracket positioning information is the position information after transforming the target measurement information based on the coordinate system corresponding to the measuring bracket.

[0066] Specifically, the multi-vehicle model measuring bracket 1 can be adjusted according to the target measurement position by the control system. Specifically, the control system can be a digital control system with programming capabilities and an external display screen. By inputting three-dimensional coordinate information into the control system, the target measurement position of the multi-vehicle model measuring bracket 1 is determined. The target measurement position includes the position in a first direction, the position in a second direction, and the position in a third direction. The control system can then issue drive control commands carrying the target measurement position.

[0067] After receiving the drive control command, the control unit generates a motor drive command to trigger the drive motor, and generates corresponding bracket positioning information based on the target measurement position included in the drive control command. The control unit then sends the motor drive command and bracket positioning information to the drive motor. The drive motor receives the motor drive command and controls the sliding assembly 100 to move in all three dimensions towards the position corresponding to the bracket positioning information. Controlling the movement of the sliding assembly 100 via electrical signals improves the positioning accuracy of the sliding assembly 100, thereby reducing measurement deviations caused by positioning errors and improving the measurement accuracy of vehicle structure data by the multi-vehicle model measurement bracket 1.

[0068] Figure 3 This shows a structural side view of the support column provided in an embodiment of the present invention, such as... Figure 3 For the support column 200, a connecting guide rail 210 is provided on one side surface of the support column 200 in the first direction; in the third direction, the bottom cross-sectional area of ​​the support column 200 is larger than the top cross-sectional area of ​​the support column 200.

[0069] In one specific embodiment, a connecting guide rail 210 is provided on the side of the support column 200 away from the sliding component 100 in the first direction, to cooperate with the connecting slider 330 to realize the movement of the connecting plate 300 in the third direction. The support column 200 can be divided into a rectangular support part and a trapezoidal support part in the third direction according to its shape. It can be considered that the top cross-sectional area of ​​the support column 200 is the rectangular area, and the bottom cross-sectional area is the area of ​​the lower base of the trapezoid. Setting the bottom cross-sectional area to be larger than the top cross-sectional area, and the bottom cross-section is connected to the first sliding structure 110, the larger the cross-sectional area, the larger the first measurement range corresponding to the first sliding structure 110, that is, the measurement range of the multi-vehicle model measuring bracket 1 can be increased. At the same time, since the top does not involve the movement of the sliding component 100, setting the top to be rectangular to reduce the top cross-sectional area can save the manufacturing cost of the multi-vehicle model measuring bracket 1.

[0070] Figure 4 This shows a structural side view of the positioning component provided in an embodiment of the present invention, such as... Figure 4 As shown, the positioning component 400 includes a positioning base plate 410 and a positioning pin 420; the positioning base plate 410 is provided with a plurality of positioning holes 411 along the first direction and the second direction.

[0071] In one specific embodiment, the positioning base plate 410 is provided with a plurality of positioning holes 411 along the first direction and the second direction, so that the positioning pin 420 can adapt to different vehicle models and adjust its position in the first direction and the second direction, thereby improving the stability of the positioning pin 420 in attaching the multi-vehicle measuring bracket 1 to the vehicle body.

[0072] In addition, the positioning component 400 can also work with the connecting plate to adjust the overall height of the multi-vehicle measuring bracket 1 in the third direction. For example, the connecting plate moves on the support column 200 via the connecting slider 330. When the position of the connecting plate is fixed and the top surface of the positioning pin 420 is at the same level as the top surface of the support column 200 in the second direction, the height of the multi-vehicle measuring bracket 1 is the sum of the height of the support column 200, the height of the sliding component 100, and the heights of the bracket base 500 and the sliding plane 510. When the position of the connecting plate is fixed and the top surface of the positioning pin 420 is higher than the top surface of the support column 200, the height of the multi-vehicle measuring bracket 1 increases. Thus, by adjusting the position of the connecting plate on the support column 200, the height of the multi-vehicle measuring bracket 1 can be adjusted, further increasing its measurement range in the third direction. This expands the scenario adaptability of the multi-vehicle measuring bracket 1 and reduces the problem of being unable to measure due to excessively large dimensions in the third direction.

[0073] In addition, such as Figure 1As shown, the multi-vehicle measuring bracket 1 may further include a bracket base 500 and a sliding plane 510, the sliding plane 510 being disposed between the first sliding structure 110 and the second sliding structure 120; the second guide rail 121 or the telescopic support portion is disposed on one side surface of the bracket base 500.

[0074] In one specific embodiment, the sliding plane 510 can be disposed between the first sliding structure 110 and the second sliding structure 120, which can increase the stability of the sliding assembly 100 during movement. Since the first sliding structure 110, the second sliding structure 120, and the lifting structure 130 are stacked and there is no order requirement, if the sliding structure is disposed below the lifting structure 130, the guide rail is disposed on one side surface of the support base 500; if the sliding structure is disposed above the lifting structure 130, the telescopic support is disposed on one side surface of the support base 500. In this utility model, the second guide rail 121 included in the second sliding structure 120 is disposed on one side surface of the support base 500, and the first sliding structure 110 is disposed between the lifting structure 130 and the second sliding structure 120.

[0075] This utility model also discloses a multi-vehicle model measuring device, including a multi-vehicle model measuring bracket as described above, wherein the number of the multi-vehicle model measuring brackets is multiple. In a specific embodiment, as shown... Figure 5 As shown, the number of multi-vehicle measuring brackets can be up to eight, working together to achieve simultaneous measurement of the vehicle body and vehicle structure. Specifically, the vehicle body can be a white body frame, and the vehicle structure can include at least the lower body assembly, engine compartment assembly, front floor assembly, and rear floor assembly. Before measurement, the control system issues a drive control command to cause the drive motor to move the measuring bracket to the corresponding spatial position, i.e., the target measurement position. After calibrating the measuring bracket to the theoretical position, the vehicle body or other vehicle structure to be measured is placed on the measuring bracket for double cantilever measurement.

[0076] As can be seen from the embodiments provided by the present invention, the multi-vehicle model measuring bracket includes a sliding component, a support column, a connecting plate, and a positioning pin. The sliding component moves in three dimensions to the target measurement position. After the sliding component moves to the target measurement position, the connecting plate, in conjunction with the positioning component, further fixes the sliding component at the target measurement position, thereby improving the accuracy of positioning and the diversity of measurement dimensions, and further improving the accuracy of measurement. In addition, since the sliding component can move in three dimensions, and the positioning component can further fix the position of the measuring bracket in the third dimension, the measuring bracket can reduce the measurement limitations caused by different vehicle models. Thus, different vehicle models can be measured based on the same measuring bracket, improving the scene adaptability and measurement efficiency of the measuring bracket.

[0077] It should be noted that the various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
