[0049] The support disc 10 is used for being connected with a stand column;The plate body 20 is rotationally connected to the support disc 10, so that the support disc 10 rotates relative to the plate body 20 around an axis of the support disc 10;The rotary driving assembly 30 is used for driving the support disc 10 to rotate around the group, a fixed part of the rotary driving assembly 30 is connected to the plate body 20, and a movable part of the rotary driving assembly 30 is connected to the support disc 10;The seat body 40 has a receiving cavity, and the support disc 10, the plate body 20 and the rotary driving assembly 30 are all arranged in the receiving cavity, and the plate body 20 is fixedly connected to an inner wall of the receiving cavity.

[0050] It can be understood that the support disc 10 is mainly used for being connected with the stand column and rotating around the axis synchronously with the stand column, the plate body 20 is used for supporting the support disc 10, so that the support disc 10 is arranged in the seat body 40, the rotary driving assembly 30 is used for providing a driving force for the support disc 10 to rotate around the group and driving the support disc 10 to rotate around the axis, and the seat body 40 provides corresponding bearing and support for the above components.

[0051] The base assembly 100 provided by the utility model, after the seat body 40 is fixed on the ground, the horizontal position of the stand column connected with the support disc 10 is fixed, the support disc 10 can be driven by the rotary driving assembly 30 to rotate around the axis relative to the plate body 20, so as to realize the rotation of the stand column around the axis, thereby improving the rotation precision of the stand column around the axis.

[0052] Please refer to Figure 3 And Figure 4 In some embodiments, the base assembly 100 further comprises a bearing member 50, the bearing member 50 comprises a connecting part 51 fixedly connected to the plate body 20 and a rotating part 52 rotating around the axis relative to the connecting part 51, one end of the rotating part 52 is connected to the support disc 10, and the other end of the rotating part 52 is connected to the movable part of the rotary driving assembly 30.

[0053] It can be understood that the connecting portion 51 is a part of the bearing member 50 that remains relatively stationary, while the rotating portion 52 is a part of the bearing member 50 that remains relatively active, thus, the connecting portion 51 is connected to the plate body 20, and the rotating portion 52 is used to be connected to the active portion of the support disc 10 and the rotating driving assembly 30.

[0054] For example, the connecting portion 51 can be a ring structure, and the rotating portion 52 is a disc structure that rotates around the shaft relative to the ring structure, and the two are in rolling or sliding.

[0055] In this way, the bearing member 50 can increase the smoothness of the rotation of the support disc 10 around the shaft. Specifically, the connecting portion 51 is fixed on the plate body 20, and the rotating portion 52 is fixed to the support disc 10, then, under the driving of the rotating driving assembly 30, the support disc 10 rotates around the shaft with the rotating portion 52.

[0056] Please refer to Figures 3 to 5 In some embodiments, the rotating driving assembly 30 includes a driving motor 31, a worm 32 connected to the output end of the driving motor 31, and a worm gear 33 connected to the rotating portion 52, and the fixed portion of the driving motor 31 is connected to the plate body 20.

[0057] It can be understood that the driving motor 31 provides driving force to drive the worm 32 to rotate around the shaft, and at the same time, the worm gear 33 connected to the worm 32 rotates around its own axis, finally, the support disc 10 rotates around the shaft relative to the plate body 20.

[0058] For example, as shown in Figure 4 and Figure 5 The support disc 10 is located on one side of the plate body 20, the worm 32 and the worm gear 33 are located on the other side of the plate body 20, and the rotating plane of the worm gear 33 is parallel to the rotating plane of the support disc 10, in this way, the overall height of the base assembly 100 in the height direction can be reduced, which is conducive to the design of miniaturization.

[0059] Please refer to Figure 5 In some embodiments, the rotating driving assembly 30 further includes a rotating disc 34, and a through hole 20a is formed on the plate body 20, and the rotating disc 34 is arranged at the through hole 20a, and the worm gear 33 is connected to the rotating portion 52 through the rotating disc 34.

[0060] It can be understood that here, the support disc 10 should be located on one side of the plate body 20, the worm 32 and the worm gear 33 should be located on the other side of the plate body 20, and the through hole 20a on the plate body 20 is used for the worm gear 33 to pass through to meet the torque transmission requirement, then, the overall height of the base assembly 100 can be designed to be smaller.

[0061] In this way, the rotating disc 34 plays a corresponding force transmission role between the worm gear 33 and the support disc 10, and can also adapt to the installation requirement of the support disc 10 in the thickness direction of the plate body 20.

[0062] Please refer to Figure 5 In some embodiments, the rotating driving assembly 30 further comprises a support 35, the support 35 is fixedly connected to the plate body 20, and the worm 32 is rotationally connected to the support 35 around the axis of the worm 32.

[0063] It can be understood that the worm 32 is fixed by the support 35, and the worm 32 rotates around the axis relative to the support 35.

[0064] For example, the support 35 has a first end and a second end, the worm 32 is sequentially arranged in the first end and the second end, and rotationally connected to the first end and the second end.

[0065] In some embodiments, the rotating driving assembly 30 comprises a driving part, a first gear connected to the output end of the driving part, and a second gear connected to the support disc 10, the first gear is meshingly connected with the second gear.

[0066] It can be understood that in this embodiment, the torque is output from the driving part to the support disc 10 by the gear transmission, and the gear transmission has higher precision.

[0067] For example, when the rotation plane of the output end of the driving part is parallel to the rotation plane of the support disc 10, then the first gear and the second gear can be ordinary gears, and the rotation planes of the two gears are also parallel to the rotation plane of the support disc 10.

[0068] For example, when the rotation plane of the output end of the driving part is perpendicular to the rotation plane of the support disc 10, then the first gear and the second gear can be bevel gears, and the rotation plane of the first gear is perpendicular to the rotation plane of the support disc 10, and the rotation plane of the second gear is parallel to the rotation plane of the support disc 10.

[0069] In this way, the driving part drives the first gear and the second gear to rotate in sequence, and finally drives the support disc 10 to rotate around the axis relative to the plate body 20.

[0070] In some embodiments, the rotating driving assembly 30 further comprises a plurality of intermediate gears, the first gear is meshingly connected with the second gear through the intermediate gears.

[0071] It can be understood that the transmission ratio between the first gear and the second gear is adjusted by the intermediate gears to adjust the output of the torque of the driving part.

[0072] For example, at least one intermediate gear can be added between the first gear and the second gear to adjust the transmission ratio between the first gear and the second gear.

[0073] Please refer to Figure 3 and Figure 4In some embodiments, the base assembly 100 comprises a sensing element 61 arranged on the support disc 10 and rotating with the support disc 10 around its own axis, and the plate body 20 is provided with a sensing element 62 which is in sensing cooperation with the sensing element 61.

[0074] It can be understood that the angle of rotation of the support disc 10 around its own axis is obtained by the sensing cooperation between the sensing element 61 and the sensing element 62, so as to achieve the requirement of precise control.

[0075] In the specific operation process, the sensing element 61 rotates with the support disc 10 around the shaft synchronously, and when the sensing element 61 rotates to the sensing element 62, the corresponding signal is collected by the sensing element 62 and outputted outwardly, so that one or more sensing elements 62 can be arranged to obtain the rotation angle and the number of rotation circles of the support disc 10.

[0076] Please refer to Figure 3 In some embodiments, the number of sensing elements 62 is multiple, and each sensing element 62 is arranged around the support disc 10 in the circumferential direction.

[0077] It can be understood that the angle of rotation of the support disc 10 around its own axis is precisely controlled by using multiple sensors.

[0078] For example, as Figure 3 shown, two sensing elements 62 are arranged on the plate body 20, and the two sensing elements 62 are arranged close to each other, that is, the distance between the two sensing elements 62 is very close, so that the sensing element 61 on the support disc 10 passes through the corresponding sensing element 62 to obtain the rotation direction of the support disc 10.

[0079] Of course, in other embodiments, multiple sensing elements 62 can also be arranged to obtain the real-time rotation angle of the support disc 10.

[0080] In a second aspect, the embodiments of the present application also provide a vehicle measurement system comprising the above-mentioned base assembly 100.

[0081] The vehicle measurement system provided by the utility model, on the basis of having the above-mentioned base assembly 100, can realize the position adjustment of the column rotating around the shaft horizontally, reduces the influence of the instability of the vehicle measurement system caused by the external force pushing the column, and is favorable for improving the column position adjustment precision.

[0082] 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.
