Abstract

A movable battery replacing platform includes a travel-driving portion used for driving the movable battery replacing platform to move on the ground; a lifting portion mounted on the travel-driving portion, for lifting a battery during the replacement of the battery; and a battery mounting portion mounted on the top of the lifting portion, for placing a battery to be replaced or a replaced battery. The battery mounting porting is provided with a battery replacing device. The device can use an unlocking device to unlock a battery locked on the bottom of an electric vehicle, automatically aligning an unlocking point of a battery locking mechanism and realizing automatic unlocking in the movement. The angle of an upper board relative to the battery unlocking position can be adjusted by a movement actuating device, so that the unlocking point of the battery can automatically fit where the movable battery replacing platform remains still.

First claim

The invention claimed is:

1. A mounting platform for performing replacing a battery of an electric vehicle, wherein the mounting platform comprises:
a mounting board;
an elastic supporting assembly which is disposed on the mounting board wherein the elastic supporting assembly supports a battery thereon, and is configured to adjust an inclination of the battery relative to the mounting board such that the battery is matched with a chassis of the electric vehicle;
a tray supported on the elastic supporting assembly wherein the tray is used to carry the battery;
wherein the elastic supporting assembly is used to adjust the inclination of the tray relative to the mounting board such that the tray is matched with the chassis of the electric vehicle;
wherein the elastic supporting assembly comprises: an elastic member having a heading end and a trailing end along a length direction thereof, wherein the heading end of the elastic member is disposed to the mounting board, and the trailing end of the elastic member is used to abut against the tray;
wherein a positioning stub is disposed on a bottom of the tray;
a receiving cavity is formed in an inner portion of the elastic member along a length direction of the elastic member, wherein the two ends of the receiving cavity extend to the heading end and the trailing end of the elastic member respectively;

the positioning stub is disposed to pass through the trailing end of the elastic member to be located in the receiving cavity.

2. The mounting platform of claim 1 , wherein the elastic supporting assembly further comprises:
a positioning member disposed on the upper board and located within the receiving cavity, wherein the positioning member is matched with the positioning stub.

3. The mounting platform of claim 2 , wherein the top of the positioning member is provided with a receiving groove, wherein the receiving groove is engaged with the positioning stub.

4. The mounting platform of claim 2 , wherein a gap more than 0 is formed between the outer wall surface of the positioning member and the inner wall surface of the elastic member.

5. The mounting platform of claim 2 , wherein the elastic supporting assembly further comprises:
a limiting member disposed on the mounting board for limiting the elastic member to the mounting board.

6. The mounting platform of claim 5 , wherein the limiting member includes a protecting sleeve and at least one penetrating member, wherein the protecting sleeve is disposed on the mounting board and covered on the heading end of the elastic member, wherein the trailing end of the penetrating member passes through the heading end of the elastic member and the protecting sleeve.

7. The mounting platform of claim 6 , wherein the trailing end of the penetrating member is located outside the positioning member.

8. The mounting platform of claim 6 , the penetrating member is a screw.

9. The mounting platform of claim 1 , wherein the elastic member is a spring.

10. The mounting platform of claim 1 , wherein the mounting platform comprises four elastic support assemblies, and two of the elastic support assemblies are front elastic support assemblies for corresponding to a front direction of the electric vehicle, and the other two elastic support assemblies are rear elastic support component for corresponding to a rear direction of the electric vehicle;
heights of the front elastic supporting assemblies are lower than heights of the rear elastic supporting assemblies and the difference in height between the front elastic supporting assemblies and the rear elastic supporting assemblies is adapted to fit the chassis of the electric vehicle.

11. A battery replacing device, wherein the battery replacing device comprises the mounting platform of claim 1 .
