Or the first connection member 80 connected to the first bracket 21 and/or the second bracket 22 may be directly connected to the chassis 10 by welding to achieve connection between the chassis 10 and the frame 20.

Alternatively, as shown in fig. 1 and 2, the frame 1 may further include a weight member 30, where the weight member 30 is connected to the chassis 10. By providing the weight 30 on the chassis 10, the center of gravity of the frame 1 can be lowered, thereby improving the stability of the frame 1 during operation.

In the embodiment in which the weight 30 is provided on the chassis 10, the frame 1 may be a frame 1 for a vehicle such as a crane or forklift, and the weight 30 lowers the center of gravity of the vehicle to avoid the vehicle from overturning during the load-bearing process.

Further, as shown in fig. 1 and 2, the projection of the weight 30 onto the chassis 10 at least partially coincides with the projection of the frame 20 onto the chassis 10. That is, at least a portion of the weight 30 is disposed under the frame 20, thereby lowering the center of gravity of the frame 20 and improving the stability of the frame 20.

The present disclosure is not limited in the manner of connection between the weight 30 and the chassis 10, and for example, the weight 30 may be connected to the chassis 10 by welding, riveting, or the like in a non-detachable manner.

Alternatively, in the present disclosure, the weight 30 may be removably attached to the chassis 10 by a removable means. Thus, the user can disassemble, assemble and replace the weight piece 30 according to specific use requirements, so as to realize the adjustment of the gravity center of the frame 1.

In one exemplary embodiment provided by the present disclosure, as shown in fig. 2, alternatively, a recess groove 11 may be formed on a sidewall of the chassis 10, the shape of the recess groove 11 being matched with the shape of the weight 30, and the weight 30 being embedded in the recess groove 11. That is, the weight 30 may be embedded in the recess 11 of the side wall of the chassis 10, which has the advantages of easy disassembly and convenient installation, and is convenient for the operator to assemble the weight 30, and since the weight 30 may be embedded in the chassis 10, there is no need to additionally install a related structure for fixing the weight 30 on the frame 1, thereby simplifying the overall structure of the frame 1.

In order to improve the stability of the fit between the weight member 30 and the chassis 10, in this disclosure, optionally, as shown in fig. 2, a limiting protrusion 110 is further formed on a groove wall of the recess 11, a notch groove 300 adapted to the limiting protrusion 110 is formed on the weight member 30, the limiting protrusion 110 is embedded in the notch groove 300, a first fixing hole 111 extending along a first direction is formed on the limiting protrusion 110, a second fixing hole 301 opposite to the first fixing hole 111 is formed on a groove wall of the notch groove 300, and the vehicle frame 1 further includes a first locking member (not shown) locked in the first fixing hole 111 and the second fixing hole 301.

Optionally, as shown in fig. 1 and 2, the frame 1 further includes a support plate 50, where the support plate 50 is disposed in the storage area 242 and connected to the chassis 10; the support plate 50 is provided with a sliding assembly for sliding contact with the article to be put in. By providing the sliding assembly on the support plate 50, friction between the lower surface of the article to be placed and the upper surface of the support plate 50 can be reduced during pushing of the article to be placed into the placement area 242, thereby making placement and removal of the article to be placed more labor-saving.

In order to improve the stability of the support plate 50, as shown in fig. 2, a third connecting hole 51 is further provided on the support plate 50, a fourth connecting hole opposite to the third connecting hole 51 is provided on the chassis 10, and fastening structures penetrating through the third connecting hole 51 and the fourth connecting hole can fix the support plate 50 on the chassis 10, so as to avoid the problem that the support plate 50 slides relative to the chassis 10 when loading and unloading the articles to be placed.

In this way, when the article to be placed moves on the support plate 50, the roller rotates along the moving direction of the article to be placed, so that the sliding contact between the article to be placed and the support plate 50 can be changed into rolling contact, and the effect of reducing the friction force between the article to be placed and the support plate 50 can be achieved.

Thus, the advancing mechanism embedded in the chute 61 can slide back and forth along the extending direction of the chute 61, thereby realizing operations such as lifting and moving of goods.

Here, it should be noted that, since the sliding rail 60 is used to bear the reciprocating movement of the advancing structure, the sliding rail 60 has higher requirements on rigidity and strength than the chassis 10, so in the present disclosure, the sliding rail 60 and the chassis 10 may be manufactured separately (i.e. without an integral molding process), and after the sliding rail 60 is manufactured, the sliding rail 60 is connected to the chassis 10.

In an exemplary embodiment provided in the present disclosure, the slide rail 60 may be detachably connected to the chassis 10, specifically, the second mounting hole 16 is formed on the chassis 10, the third mounting hole 62 is formed on the slide rail 60, and the third fastener sequentially passes through the third mounting hole 62 and the second mounting hole 16 to lock the slide rail 60 to the chassis 10.
