a guide rail;

the guide wheel is installed on the vehicle body, and the guide wheel is arranged on the guide rail in a rolling mode.

Optionally, the guide wheels are provided in two numbers, and the two guide wheels are clamped on two sides of the guide rail.

Optionally, the drive seat with be connected through the articulated shaft between the automobile body, articulated shaft periphery cover is equipped with self-lubricating copper sheathing.

Optionally, a bearing is arranged between the idler wheel and the driving seat.

Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:

the utility model discloses a vehicle body actuating mechanism drives the automobile body and moves ahead under the motor drive gear condition, and when the rack installation straightness accuracy was not good, the drive seat was around articulated center trace swing, and the depended wheel guarantees that wheel and rack mesh completely, guarantees the linearity of automobile body motion through guide rail and leading wheel in addition.

As shown in fig. 3, the vehicle body 9 needs to be moved in the direction C for the apparatus bottom view and driven by the vehicle body driving mechanism.

The vehicle body driving mechanism includes a rack 1 disposed substantially along the C direction.

The vehicle body driving mechanism further comprises a driving seat 2, and the driving seat 2 is hinged with a vehicle body 9 through a hinge shaft 8. The periphery of the articulated shaft 8 is also sleeved with a self-lubricating copper bush so as to ensure the smoothness of the driving seat 2 relative to the swing of the vehicle body 9.

The driving seat 2 is provided with a gear 5 and a depended wheel 6, the gear 5 and the depended wheel 6 are respectively positioned on two sides of the rack 1, and the rack 1 is clamped by the gear 5 and the depended wheel 6. Wherein the gear wheel 5 meshes with the gear rack 1. The idler wheel 6 ensures that the gear 5 is completely meshed with the rack 1. A bearing is arranged between the idler wheel 6 and the driving seat 2 to ensure the smoothness of the rotation of the idler wheel 6.

As shown in fig. 1 and 2, the driving base 2 is further provided with a motor 7 for driving the gear 5 to rotate.

As shown in fig. 1 and 3, the vehicle body 9 is further provided with a pair of guide wheels 4, the guide wheels 4 are clamped on two sides of the guide rail 3, the guide rail 3 is installed on the ground, and the guide wheels 4 are matched with the guide rail 3 to ensure the linearity of the movement of the vehicle body 9.

In other embodiments, the guide wheels 4 and the guide rail 3 can be arranged in other manners, such as only one guide wheel 4 is arranged, and the guide wheel 4 is arranged on the guide rail 3 in a rolling manner; for example, two parallel guide rails 3 and a guide wheel 4 are provided, and the guide wheel 4 is held between the guide rails 3. In short, the guide wheels 4 are engaged with the guide rail 3 in order to move the vehicle body 9 along the extending direction of the guide rail 3.

In this example, even if the rack 1 is installed to form a small angle with the guide rail 3, the vehicle body 9 can smoothly advance along the guide rail 3 by the minute swing of the driving seat 2 about the hinge shaft 8.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
