In a third straight line 500 direction substantially parallel to the front-rear direction of the power module 15, a width D1 of the holding portion 1531 in the direction parallel to the third straight line 500 is smaller than a width D2 of the second receiving groove 1523 in the direction parallel to the third straight line 500, so that the handle 153 can be easily grasped by the serviceman when the handle 153 is in the first state. In addition, the connecting portion 1532 can slide freely in the direction of the first straight line 300 in the sliding groove set 1521. As shown in fig. 6, the connecting portion 1532 is at least partially disposed in the sliding groove set 1521, and a sliding chuck 1533 is formed at an end of the connecting portion 1532 away from the holding portion 1531. The width of the connecting portion 1532 in the direction parallel to the third straight line 500 is D3, the width of the slide chuck 1533 in the direction parallel to the third straight line 500 is D4, and the width of the inner wall of the first slide slot 1521a in the direction parallel to the third straight line 500 is D5. It is understood that D3 is less than D4, and D4 is equal to or less than D5. Specifically, when the handle 153 slides to the farthest end away from the upper cover 152 along the first straight line 300, the handle 153 is prevented from being separated from the upper cover 152 when freely sliding along the first straight line 300 through the matching of the sliding clamp 1533 and the limiting portion 1521c, the stability of the power module 15 when the handle 153 is held is increased, the size of the upper cover 152 is reduced, the effective space is not occupied, and the requirement for the arrangement of the space volume of the whole vehicle is met.

In one implementation, the handle 153 has a protruding length L1 with respect to the end surface, and the upper cover 152 has an extending length L2 along the first straight line 300.

In one implementation, the ratio of the protruding length L1 of the handle 153 relative to the end surface to the extending length L2 of the upper cover 152 along the first straight line 300 is greater than or equal to 0.66 and less than 1. Further, the ratio of L1 to L2 is equal to or greater than 0.74 and equal to or less than 0.92. In this embodiment, the ratio of L1 to L2 is equal to 0.83. Through the arrangement, the size of the upper cover 152 is reduced, the effective space is not occupied, and the space volume arrangement requirement of the whole vehicle is met.

As shown in fig. 5, the upper cover further includes a limit stop 1524, and the limit stop 1524 is at least partially disposed on the sliding groove set 1521. The chute group 1521 is provided with the connecting hole that is used for fixed limit stop 1524, through bolt with limit stop 1524 fixed connection to chute group 1521, and limit stop 1524 is the metal block of rectangle basically to play the guard action to connecting portion 1532 through limit stop 1524, prevent to lead to connecting portion 1532 to warp because of external factors such as collision, and then influence the normal work of handle 153. When the limit stopper 1524 is connected to the chute set 1521, the connecting portion 1532 is disposed between the limit stopper 1524 and the chute set 1521, so that the movement of the connecting portion 1532 in the left-right direction is limited by the limit stopper 1524, and the connection portion 1532 is prevented from being separated from the chute set 1521 and the handle 153 is prevented from being separated from the upper cover 152 when the handle 153 is in the second state, which may damage the power module 15.

In one implementation, the top cover further includes a housing cover (not shown) at least partially disposed on the top cover 152. The housing cover and the upper cover 152 are connected by a snap, which is convenient to detach, and the housing cover is mounted to the chute set 1521 for protecting the chute set 1521 and the connecting part 1532, so that the connecting part 1532 is firmly arranged in the chute, and the handle 153 is prevented from being separated from the upper cover 152.

As shown in fig. 5, the upper cover further includes an explosion-proof valve 1525, and the explosion-proof valve 1525 is at least partially disposed on one side of the upper cover 152. The explosion-proof valve 1525 is provided with a plurality of vent holes, and air exchange between the inside of the power module 15 and the external environment of the power module 15 is realized through the vent holes, thereby preventing the power module 15 from exploding when the internal air pressure is too high.

As an implementation, the bottom cover 154 is at least partially connected to the housing 151, and the bottom cover 154 closes the other end of at least a portion of the accommodating space 200 along the first line 300. A closed receiving space 200 is formed by the bottom cover 154, the housing 151 and the top cover 152, so that the cell is protected.
