Abstract

The present application provides a chassis, a vehicle, a device for manufacturing a vehicle and a method for manufacturing a vehicle. The chassis includes at least two movable bodies that are continuously arranged along a first preset direction, and by adjusting a position of at least one movable body in the first preset direction, a length of the chassis in the first preset direction can be changed so as to enable the chassis to adapt to the vehicle body of a different length. Since each movable body is provided at an adjacent movable body thereof with a position adjustable in a preset direction, the chassis is made into a telescopic structure that is adjustable in length. The length of the chassis can be adjusted according to the requirements to enable the chassis to adapt to the vehicle body of a different length.

First claim

What is claimed is:

1. A chassis for a vehicle, wherein the chassis comprises at least two movable bodies continuously arranged along a first preset direction;
each movable body being provided at an adjacent movable body thereof with a position adjustable in the first preset direction, and by adjusting a position of at least one movable body in the first preset direction, a length of the chassis in the first preset direction being changed so as to enable the chassis to adapt to a vehicle body of a different length;
wherein the at least two movable bodies comprise:
a first movable body for mounting a front wheel; and
a second movable body for mounting a rear wheel;

the at least two movable bodies further comprises a third movable body provided with an accommodating space for accommodating a battery cell; and
the first movable body, the third movable body and the second movable body are arranged in order in the first preset direction;
the third movable body comprises:
a first longitudinal beam arranged along the first preset direction;
a second longitudinal beam arranged along the first preset direction;
a first cross beam arranged along a second preset direction and connected between the first longitudinal beam and the second longitudinal beam; and
a second cross beam arranged along the second preset direction and connected between the first longitudinal beam and the second longitudinal beam;
wherein the first longitudinal beam, the second longitudinal beam, the first cross beam, and the second cross beam jointly define the accommodating space;
the first cross beam is provided at the first longitudinal beam and the second longitudinal beam with a position adjustable along the first preset direction, the first cross beam is connected to the first movable body, and by adjusting a position of the first movable body, a position of the first cross beam can be changed to adjust a size of the accommodating space; and/or
the second cross beam is provided at the first longitudinal beam and the second longitudinal beam with a position adjustable along the first preset direction, the second cross beam is connected to the second movable body, and by adjusting a position of the second movable body, a position of the second cross beam can be changed to adjust a size of the accommodating space.

2. The chassis according to claim 1 , wherein the first movable body comprises:
a first connecting beam provided at the first longitudinal beam with a position adjustable in the first preset direction;
a second connecting beam provided at the second longitudinal beam with a position adjustable in the first preset direction; and
an external cross beam, through which the first connecting beam and the second connecting beam are connected.

3. The chassis according to claim 2 , wherein the first connecting beam is provided at one end of the external cross beam with a position adjustable in the second preset direction; and
the second connecting beam is provided at another end of the external cross beam with a position adjustable in the second preset direction.

4. The chassis according to claim 3 , wherein the first connecting beam comprises a first connecting portion and a second connecting portion connected to the first connecting portion;
the second connecting beam comprises a third connecting portion and a fourth connecting portion connected to the third connecting portion;
the first connecting portion and the third connecting portion are respectively configured to be inserted into and matched with the first longitudinal beam and the second longitudinal beam in the first preset direction; and
the second connecting portion and the fourth connecting portion are respectively configured to be inserted into and matched with two ends of the external cross beam in the second preset direction.

5. The chassis according to claim 1 , wherein the first cross beam is a telescopic structure that is telescopic along the second preset direction; and
the second cross beam is a telescopic structure that is telescopic along the second preset direction.

6. The chassis according to claim 1 , wherein the third movable body further comprises:
a support beam, wherein at least one support beam is connected between the first longitudinal beam and the second longitudinal beam and/or between the first cross beam and the second cross beam to split the accommodating space into a plurality of accommodating grids for accommodating the battery cell.

7. The chassis according to claim 1 , wherein the chassis further comprises:
a locking unit for locking or releasing two adjacent movable bodies;
when the locking unit locks the two adjacent movable bodies, relative positions of the two adjacent movable bodies are fixed; and
when the locking unit releases the two adjacent movable bodies, relative positions of the two adjacent movable bodies are adjustable.

8. The chassis according to claim 7 , wherein one movable body of the two adjacent movable bodies is provided with a first plugging portion, and the other movable body of the two adjacent movable bodies is provided with a second plugging portion;
the first plugging portion is movably inserted into the second plugging portion along the first preset direction; and
the locking unit is configured to lock or release the first plugging portion and the second plugging portion.

9. The chassis according to claim 8 , wherein each locking unit comprises:
a locking pin movably provided at the first plugging portion, wherein with a plurality of locking holes arranged on the second plugging portion at intervals along the first preset direction, the locking pin is configured to be selective inserted into one locking hole; and
an elastic piece acting between the locking pin and the first plugging portion for providing an elastic force to the locking pin so as to enable the locking pin to be inserted into one locking hole aligned therewith.

10. A vehicle, wherein the vehicle comprises:
a vehicle body, and
the chassis according to claim 1 , wherein the vehicle body is connected to the chassis.

11. The vehicle according to claim 10 , wherein the vehicle body is detachably connected to the chassis.

12. The vehicle according to claim 11 , wherein the vehicle further comprises:
a locking assembly, through which the vehicle body and the chassis are detachably connected.

13. The vehicle according to claim 12 , wherein the locking assembly comprises:
a locking piece comprising a limiting portion and a rod portion connected to the limiting portion, wherein an inserting hole is provided on the rod portion, and the rod portion is configured to be penetrated into the vehicle body and the chassis; and
a wedge block configured to compact the vehicle body and the chassis jointly together with the limiting portion upon being inserted into the inserting hole.
