For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0047] Firstly, please refer to Figure 1 and Figure 2 The lifting assembly 100 provided by the embodiment of the present application comprises a column box body 10, a lifting mechanism 20, a driving assembly 30 and a bearing member 40.

[0048] The column box body 10 is in a hollow structure; the lifting mechanism 20 is slidingly connected to the column box body 10 and moves up and down along a first direction X relative to the column box body 10; the driving assembly 30 is arranged in the column box body 10, and the output end of the driving assembly 30 is connected to the lifting mechanism 20 to drive the lifting mechanism 20 to move up and down along the first direction X; the bearing member 40 is slidingly connected to the lifting mechanism 20 and moves up and down along the first direction X relative to the lifting mechanism 20, and the bearing member 40 is used for supporting a cross beam.

[0049] It can be understood that the column box body 10 is the main part of the lifting assembly 100 and is used for supporting and bearing the respective components, the lifting mechanism 20 is the part that moves relative to the column box body 10 along the first direction X, the driving assembly 30 provides a power source for the movement of the lifting mechanism 20 relative to the column box body 10, and the bearing member 40 moves synchronously with the lifting mechanism 20, thereby driving the cross beam to obtain a movement range along the first direction X, i.e. a movement range along the height direction of the column box body 10. At the same time, the bearing member 40 can also move relative to the lifting mechanism 20, which is the main reason why the bearing member 40 can obtain a larger movement range.

[0050] The structure of the column box 10 can not be limited, and can be a cylindrical column box 10, a square column box 10, a pentagonal column box 10, etc. The structure of the lifting mechanism 20 includes but is not limited to a lifting frame, a lifting plate body, a lifting support, etc. Meanwhile, the lifting mechanism 20 is sleeved on the outer side of the column box 10. The driving assembly 30 can be a telescopic cylinder or a screw mechanism, etc. which can output the power required for linear motion. The carrier 40 is used to connect the cross beam to drive the cross beam to move synchronously. Meanwhile, the carrier 40 can slide relative to the lifting mechanism 20 in the first direction X. Therefore, when the lifting mechanism 20 slides relative to the column box 10 to the limit height, the carrier 40 can continue to slide relative to the lifting mechanism 20, thereby increasing the target height interval.

[0051] For example, the carrier 40 can slide relative to the lifting mechanism 20 through a sliding structure such as a sliding block or a pulley. The power source for the sliding of the carrier 40 relative to the lifting mechanism 20 can be human power or mechanical power. For example, when the lifting mechanism 20 is at the lower limit height position relative to the column box 10, the carrier 40 can continue to slide relative to the lifting mechanism 20 manually. For another example, when the lifting mechanism 20 is at the upper limit height position relative to the column box 10, the carrier 40 can continue to slide relative to the lifting mechanism 20 through a driving motor or other power mechanism.

[0052] The driving assembly 30 in the column box 10 drives the lifting mechanism 20 to move up and down in the first direction X, so as to satisfy the certain activity range of the cross beam in the height direction on the carrier 40. Meanwhile, the carrier 40 can continue to stretch and contract relative to the lifting mechanism 20 along the first direction X, thereby further increasing the activity range of the cross beam in the height direction. In this way, the lifting assembly 100 provided by the present application has a wider target height interval.

[0053] Please refer to Figure 2 In some embodiments, the lifting mechanism 20 includes a lifting part 21 in a hollow structure and a connecting part 22 connected to one end of the lifting part 21. The lifting part 21 is sleeved on the outer side wall of the column box 10. The carrier 40 is slidingly connected to the lifting part 21. The connecting part 22 is connected to the output end of the driving assembly 30.

[0054] It can be understood that the lifting part 21 is the main part of the lifting mechanism 20. The structure of the lifting part 21 is not limited, for example, the lifting part 21 can be a plate structure, a cylindrical structure, a support structure, etc. The lifting part 21 should be adapted to the outer side wall of the column box 10. The connecting part 22 is a connecting structure for connecting the lifting part 21 and the output end of the driving assembly 30, so as to drive the lifting part 21 to slide relative to the column box 10.

[0055] For example, as shown in the figure, the column box body 10 is a cubic structure, the lifting portion 21 is a plate-like structure, and is provided on two opposite outer side walls of the column box body 10 , and the connecting portion 22 connects the two plate-like structures.

[0056] For example, the column box 10 is a cylindrical structure, the lifting portion 21 is a cylindrical sleeve sleeved on the cylindrical structure, and the connecting portion 22 is a baffle sealed at one end of the cylindrical sleeve.

[0057] For example, the column box 10 is a cubic structure, the lifting part 21 can also be a bracket structure arranged around the outer wall of the column box 10, and the connecting part 22 is an L-shaped connecting plate, connecting the bracket structure and the output end of the driving component 30.

[0058] In this way, the lifting part 21 is sleeved on the outer wall of the column box 10, and the connecting part 22 is used to connect to the output end of the driving component 30. Then, when the driving component 30 outputs torque, it drives the connecting part 22 and the lifting part 21 to move up and down relative to the column box 10 along the first direction X.

[0059] Please refer to Figure 2 In some embodiments, the lifting portion 21 includes at least two lifting plates 211, each lifting plate 211 is arranged on the outer wall of the column box 10, the bearing member 40 is slidably connected to two of the lifting plates 211, and the connecting portion 22 is connected to the same end of each lifting plate 211.

[0060] It can be understood that the lifting plate 211 can be a non-enclosed structure, for example, the lifting part 21 is composed of only two lifting plates 211, and is surrounded on the outer wall of the column box body 10, or the lifting plate 211 can also be a closed structure, for example, the lifting part 21 can be surrounded by more than three lifting plates 211 to form a closed structure, and then is mounted on the outer wall of the column box body 10.

[0061] In this way, the supporting member 40 selects two of the lifting plates 211 for sliding connection to meet the relative sliding requirement.

[0062] Please refer to Figure 2 In some embodiments, the lifting assembly 100 includes a slide rail 23 and a slider 24 slidably connected to the slide rail 23 . The slide rail 23 is arranged on the outer wall of the column box 10 and extends along the first direction X. The slider 24 is arranged on the lifting plate 211 .

[0063] It can be understood that the relative sliding between the lifting plate 211 and the column box 10 is achieved by the sliding fit between the slide rail 23 and the slider 24 .

[0064] For example, two slide rails 23 are arranged on the outer side wall of the column box 10, and the two slide rails 23 are arranged along the first direction X and are spaced apart along the direction perpendicular to the first direction X. At least two slide blocks 24 are arranged on the lifting plate 211.

[0065] For example, two slide rails 23 are arranged on the outer side wall of the column box 10, and the two slide rails 23 are arranged along the first direction X and are spaced apart along the direction perpendicular to the first direction X. At least two slide blocks 24 are arranged on the lifting plate 211. Figure 2 In some embodiments, the bearing 40 includes a bearing plate 41 for connecting the cross beam and a sliding plate 42 connected to the opposite sides of the bearing plate 41. The sliding plate 42 is slidingly connected to the corresponding lifting plate 211.

[0066] It can be understood that the bearing 40 has a U-shaped structure and surrounds the side walls of the two lifting plates 211 to simultaneously satisfy the support of the cross beam and the relative sliding of the lifting plate 211.

[0067] For example, a structure similar to the slide rail 23 and the slide block 24 can be arranged between the sliding plate 42 and the lifting plate 211 to satisfy the relative sliding, or a structure similar to the slide groove and the insertion column can be arranged between the sliding plate 42 and the lifting plate 211, and the insertion column slides in the slide groove to satisfy the sliding requirement.

[0068] For example, a structure similar to the slide rail 23 and the slide block 24 can be arranged between the sliding plate 42 and the lifting plate 211 to satisfy the relative sliding, or a structure similar to the slide groove and the insertion column can be arranged between the sliding plate 42 and the lifting plate 211, and the insertion column slides in the slide groove to satisfy the sliding requirement. Figure 2 Figure 3 In some embodiments, a slide groove 25 is formed on the lifting plate 211, the slide groove 25 is arranged along the first direction X, and a first pulley 43 slidingly fitted in the slide groove 25 is arranged on the sliding plate 42.

[0069] It can be understood that the first pulley 43 cooperates with the groove wall of the slide groove 25 to slide along the extension direction of the slide groove 25 relative to the lifting plate 211.

[0070] For example, a structure similar to the slide rail 23 and the slide block 24 can be arranged between the sliding plate 42 and the lifting plate 211 to satisfy the relative sliding, or a structure similar to the slide groove and the insertion column can be arranged between the sliding plate 42 and the lifting plate 211, and the insertion column slides in the slide groove to satisfy the sliding requirement. Figure 2 In some embodiments, the bearing 40 further includes a second pulley 44, the second pulley 44 is arranged on the side of the bearing plate 41 facing the column box 10, and the second pulley 44 abuts against the outer side wall of the column box 10 or the lifting plate 211.

[0071] It can be understood that the second pulley 44 further increases the smoothness of the bearing 40 during the sliding process relative to the lifting plate 211.

[0072] Here, when the lifting plate 211 does not completely surround the column box 10, the second pulley 44 abuts against the outer side wall of the column box 10 to slide, and when the lifting plate 211 completely surrounds the column box 10, the second pulley 44 abuts against the lifting plate 211 to slide.

[0073] ​In some embodiments, the lifting part 21 comprises a lifting plate 211 surrounding the outer sidewall of the column box 10, and a transition plate (not shown in the figure) slidingly connected to the side of the lifting plate 211 away from the column box 10, and the carrier 40 is slidingly connected to the transition plate.

[0074] Understandably, the transition plate can slide independently relative to the lifting plate 211 in the first direction X, and the carrier 40 is slidingly connected to the transition plate, so as to further improve the moving range of the cross beam on the carrier 40 in the height direction.

[0075] For example, the transition plate slides relative to the lifting plate 211 through a structure similar to the slide rail 23 and the sliding block 24, and the power for the sliding of the transition plate relative to the lifting plate 211 can be manual or mechanical. In addition, the carrier 40 can also slide relative to the transition plate through a structure similar to the slide rail 23 and the slide rail 23, and the power for the sliding of the transition plate relative to the lifting plate 211 can also be manual or mechanical.

[0076] In this way, the transition plate further increases the moving range of the carrier 40 in the height direction of the column box 10.

[0077] Please refer to Figure 1 , Figure 4 and Figure 5 In some embodiments, the driving assembly 30 comprises a push rod 31 connected to the connecting part 22, a cylinder body 32 slidingly sleeved on the push rod 31, and a motor 33 for driving the push rod 31 to extend and retract, the cylinder body 32 is connected to the column box, the motor 33 is arranged along the length direction of the push rod 31, the motor 33 is installed on the cylinder body 32, and the motor 33 is in transmission connection with the push rod 31.

[0078] In this way, the driving assembly 30 is linear as a whole, so as to reduce the cross-sectional area of the driving assembly 30, and further reduce the cross-sectional area of the column box 10 and the weight.

[0079] In a second aspect, the embodiments of the present application provide a vehicle measurement system, comprising the lifting assembly 100.

[0080] The vehicle measurement system provided by the utility model has the lifting assembly 100, and the height range of the target of the vehicle measurement system is wider.

[0081] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement and improvement made within the spirit and principle of the utility model should be included in the protection range of the utility model.
