In order to make those skilled in the art better understand the solution of the present invention, the technical solution of the present invention is further described below with reference to specific embodiments.

Example 1

Referring to Figures 1-3 , a double-support car support structure includes a fixed base frame 1 , a movable cross frame 2 , a first support kick 3 and a second support kick 4 .

The fixed base frame 1 is used as the bearing base of the entire double-support car support structure, and is fixed on the vehicle body during use. Specifically, the fixed base frame 1 includes a top plate 1.1 and side support walls 1.2 arranged on both sides of the top plate. , in order to enhance the strength of the two side support walls 1.2, a transverse support 1.3 is arranged between the bottoms of the two side support walls 1.2, and the transverse support 1.3 ensures that the two side support walls 1.2 are not deformed; The top plate 1.1 is also provided with mounting holes 1.4 for fixing with the vehicle body.

Through holes 1.21 for installing the movable cross frame 2 are symmetrically arranged on the two side support walls 1.2, the movable cross frame 2 is transversely inserted therein, and the diameter of the through holes 1.21 is larger than the cross-sectional size of the movable cross frame 2 , so that the movable cross frame 2 can rotate in the through hole 1.21. In this embodiment, the movable cross frame 2 is in the shape of a long strip, and two ends in the transverse direction are provided with mounting portions 2.1 for mounting the support kicks, and the mounting portions 2.1 are in the shape of U-shaped mounting holes.

The first support kick 3 is installed at one end of the movable cross frame 2 and is located on the outer side of the side support wall 1.2. Specifically, the top of the first support kick 3 penetrates into the installation portion 2.1 of one end of the movable cross frame 2. , and the first support kick 3 and the movable cross frame 2 are connected by a first pin, the movable cross frame 2 is provided with a hole m for installing the first pin, and the hole is a horizontally arranged long hole, so that The first pin shaft can have a displacement space in a certain lateral direction along the long hole.

Similarly, the second support kick 4 is installed at the other end of the movable cross frame 2 and is located on the outer side of the side support wall 1.2. Specifically, the top of the second support kick 4 penetrates into the other end of the movable cross frame 2. In the installation part of one end, and the second support kick 4 and the movable cross frame 2 are connected by a second pin shaft, the movable cross frame 2 is provided with a hole for installing the second pin shaft, and the hole is a horizontally arranged length. hole, so that the second pin shaft can have a certain displacement space in the lateral direction along the long hole.

The top of the first support kick 3 and the top of the second support kick 4 are connected by a spring, and the spring provides the first support kick 3 and the second support kick 4 with a force against the side support wall 1.2. Under the action of the spring, the top of the first support kick 3 and the top of the second support kick 4 abut against the outer wall of the side support wall 1.2. Specifically, the two ends of the spring can be connected to the first support kick respectively. 3 body and on the body of the second support kick 4; alternatively, both ends of the spring can also be connected to the first pin on the top of the first support kick 3 and the second pin on the top of the second support kick 4. In addition, the two side support walls 1.2 of the fixed base frame 1 are inclined surfaces inclined outward from top to bottom, so that when the first support kick 3 and the second support kick 4 are in the supporting state, the shape, so that the distance between the support points on both sides of the car body (the bottom end of the first support kick and the bottom end of the second support kick as two support points) is large enough to increase the stability of the support to the car body; When the support kick and the second support kick are raised, the first support kick and the second support kick are retracted inward, thereby reducing the lateral footprint of the first support kick and the second support kick.

Further, a plurality of limit structures are provided on the side support walls 1.2 of the fixed base frame 1 to limit the support or lift position of the support kick, specifically including:

The first limit recess a is arranged vertically along the side support wall 1.2. After the support kick falls into the first limit recess a, under the action of the spring, the support kick can be maintained in a vertical support state.
