Description

Technical Field

[0001] The utility model relates to the technical field of connection structures, in particular to a quick positioning and locking mechanism for a superstructure and a supporting chassis of a new energy commercial vehicle. Background Art

[0002] New energy commercial vehicles have a supporting chassis and a superstructure mounted on the supporting chassis. With the growing demand for urban logistics and distribution, the superstructure of new energy commercial vehicles needs to be replaced more frequently. The existing connection structure between the superstructure and the chassis cannot quickly position the superstructure during replacement, which cannot meet the demand for rapid replacement of the superstructure. Moreover, after installation, the superstructure is prone to deviation due to lack of clamping. Therefore, we propose a quick positioning and locking mechanism between the superstructure and the supporting chassis of new energy commercial vehicles. Utility Model Content

[0006] A lower connecting assembly is correspondingly provided below the U-shaped frame. The lower connecting assembly includes an L-shaped plate, a guide head, a self-locking bolt and a self-locking nut. The guide head of the lower connecting assembly passes upward through the elliptical hole and the cross hole and is placed in the U-shaped groove of the U-shaped frame.

[0007] Furthermore, the positioning plate is fitted and fixed to the bottom of the U-shaped groove, and the aperture size of the cross hole is greater than or equal to the major axis aperture size of the elliptical hole.

[0008] Furthermore, the top plate of the L-shaped plate is fitted with the outer bottom of the U-shaped frame, and a rotating hole is opened in the middle of the top plate of the L-shaped plate. A self-locking bolt is rotatably connected in the rotating hole. The top of the self-locking bolt passes through the top plate of the L-shaped plate and is fixed with a guide head. A self-locking nut is threadedly connected to the self-locking bolt located below the top plate of the L-shaped plate.

[0009] Furthermore, a gasket is sleeved on the self-locking bolt located between the self-locking nut and the top plate of the L-shaped plate.

[0010] Furthermore, after the guide head passes through the elliptical hole and the cross hole upward, the self-locking bolt is rotated to clamp the bottom of the guide head between the cross hole and the bottom wall of the U-shaped groove of the U-shaped frame.

When in use, the guide head is inserted into the interior of the corresponding elliptical hole, and then continues to move upward to pass through the cross hole. The self-locking bolt is manually rotated 90 degrees to form a vertical angle between the guide head and the elliptical hole. The self-locking bolt is then pulled downward to drive the guide head so that the bottom of the guide head is clamped into the interior of the cross hole. After the clamping is completed, the self-locking nut is manually tightened to fix the guide head. At this time, the cross hole can clamp and position the guide head, which is convenient for connecting the upper assembly with the supporting frame. At the same time, the clamping and positioning can prevent the upper assembly from deviating. BRIEF DESCRIPTION OF THE DRAWINGS
