[0020] Example 1

[0021] like Figure 1-3 As shown, a battery-swap power battery ice-breaking ejection structure includes a power battery frame 1, an ejection cam 2, a power battery body 3 and a motor 9, wherein the power battery frame 1 covers and is fixed on top of the power battery body 3, and ejection cams 2 are respectively provided in the power battery frame 1 at the four corners of the top of the power battery body 3;

[0022] The ejection cam 2 includes a cam 4, a rotating shaft 5, a sliding mechanism and an ejection rod 7, wherein the cam 4 body is provided with an arc-shaped guide groove 10, and the sliding mechanism is connected in the arc-shaped guide groove 10. The cam 4 body is connected to the side wall of the power battery frame 1 through the rotating shaft 5, and the bottom of the sliding mechanism is in contact with the flange 8 of the power battery body 3. The motor 9 is fixed in the side wall of the power battery frame 1, and its drive shaft is connected to the rotating shaft 5, which can drive the rotating shaft 5 to rotate, thereby driving the cam 4 to rotate.

[0023] The front and rear ends of the left and right side walls of the power battery frame 1 are respectively provided with grooves 11 , and a bearing seat is provided on the top of the groove 11 . The cam 4 body is connected to the bearing seat through the rotating shaft 5 , and a motor 9 is fixed inside the groove 11 .

[0024] The sliding mechanism is an integrated part, including a sliding pin 6 and an ejector rod 7 arranged at the bottom of the sliding pin 6, wherein the ejector rod 7 extends into the cam 4, so that the sliding pin 6 is fitted and connected in the arc-shaped guide groove 10.

[0025] The ejector rod 7 includes a rod portion and a bottom plate located at the bottom of the rod portion, wherein the rod portion extends into the cam 4 , and a sliding pin 6 is provided above the rod portion, and the bottom plate contacts the flange 8 of the power battery body 3 .

[0026] The power battery frame 1 is installed under the floor of the vehicle by means of bolt connection. The power battery body 3 is fixed to the power battery frame 1 by means of a battery replacement locking mechanism. The ejection cam 2 with a guide groove is arranged between the power battery body 3 and the power battery frame 1. The reciprocating motion converted from the rotation of the cam mechanism is used to force the power battery body 3 and the power battery frame 1 to move or tend to move away from each other, thereby assisting the power battery body 3 to separate from the power battery frame 1 when the power battery frame 1 and the power battery body 3 are frozen by ice or snow or stuck by mud and sand.

[0027] Furthermore, the ejection cam 2 with a guide groove is arranged at the four corners of the power battery frame 1 and contacts the corresponding positions of the power battery body 3. The ejection cam 2 with a guide groove is fixed to the power battery frame 1 by means of bolt connection, and the ejection rod 7 is pressed on the flange 8 of the power battery body 3.

[0028] Furthermore, the flange 8 is a part of the load-bearing structure on the power battery body 3, which can withstand the ejection force of the ejection cam 2 with the guide groove, thereby ensuring structural strength while meeting functional requirements.

[0029] Furthermore, the ejection cam 2 with the guide groove includes a cam 4 , a rotating shaft 5 , a sliding pin 6 and an ejection rod 7 .

[0030] During operation, the motor 9 drives the cam 4 to rotate clockwise, and the sliding pin 6 slides in the arc-shaped guide groove 10 according to the guide groove track, driving the ejector rod 7 to move downward. At the same time, the rotating shaft 5 is connected to the power battery frame 1, so the ejector rod 7 will move in the direction in which the power battery body 3 is separated from the power battery frame 1, and then support the flange 8 of the power battery body 3 to eject the power battery body 3.

[0031] After the power battery body 3 is successfully separated from the power battery frame 1, the motor 9 drives the ejection cam 2 to rotate counterclockwise, and the sliding pin 6 slides in the arc-shaped guide groove 10 according to the guide groove track, driving the ejection rod 7 to move upward. At the same time, the rotating shaft 5 is connected to the power battery frame 1, so the ejection rod 7 will retract into the lower surface of the power battery frame 1, ensuring that after the new battery is replaced, the new battery can be smoothly installed back into the power battery frame 1, thereby completing the entire battery replacement process.

[0032] Example 2

[0033] A battery-swap power battery ice-breaking ejection structure comprises a power battery frame 1, an ejection cam 2 with a guide groove, and a power battery body 3, wherein the power battery frame 1 is installed under the floor of the entire vehicle by means of bolt connection, and the power battery body 3 is fixed to the power battery frame 1 by means of a battery-swap locking mechanism, and the ejection cam 3 with a guide groove is arranged between the power battery body 3 and the power battery frame 1. The reciprocating motion converted from the rotation of the cam mechanism is used to force the power battery body 3 and the power battery frame 1 to produce a movement or movement trend away from each other, thereby assisting the power battery body 3 to separate from the power battery frame 1 when the power battery frame 1 and the power battery body 3 are frozen by ice or snow or stuck by mud and sand.

[0034] The ejection cams 2 with guide slots are located at the four corners of the power battery frame, contacting corresponding positions on the power battery body. The ejection cams 2 with guide slots are bolted to the power battery frame 1, and the ejection rod 7 presses against the flange 8 of the power battery body 3. The flange 8 is a load-bearing structure on the power battery body 3, capable of withstanding the ejection force exerted on it by the ejection cams 2 with guide slots, ensuring structural strength while meeting functional requirements.

[0035] The ejection cam 2 with the guide groove includes a cam 4 , a rotating shaft 5 , a sliding pin 6 and an ejection rod 7 .
