In some embodiments, the bottom wall of the groove <NUM> is provided with a first opening <NUM>, and the first connector <NUM> passes through the first opening <NUM> to output electric energy of the plurality of battery cells <NUM> to an outside of the box <NUM> through the first connector <NUM>. The first connector <NUM> passes through the first opening <NUM> to facilitate simultaneous connection to the second connector <NUM> and the plurality of battery cells <NUM> inside the box <NUM>, so that the first connector <NUM> has one portion located in the groove <NUM> and the other portion accommodated in the box <NUM>, which reduces the occupation of space of the groove <NUM> by the first connector <NUM> to leave much space for the second connector <NUM>, so that the second connector <NUM> could be located in the groove <NUM> to the maximum extent as much as possible, and further, the structure of the power consumption device <NUM> is more compact.

The base <NUM> covers the first opening <NUM> from the inner side of the box <NUM>, which has a sealing effect on the first opening <NUM>. After the second connector <NUM> is butted with the first connector <NUM>, the base <NUM> can prevent the first connector <NUM> from moving along a direction approaching the second connector <NUM>, avoiding the second connector <NUM> pulling off the first connector <NUM> which may cause an electrical disconnection between the first connector <NUM> and the plurality of battery cells <NUM>.

The sealing member is disposed in the box <NUM>, which could avoid sealing failure caused by external wear, corrosion and the like. In addition, the sealing member is disposed in the box <NUM>, which avoids the sealing member to occupy the space of the groove <NUM>, so that the groove <NUM> can leave much more space for the butting between the second connector <NUM> and the first connector <NUM>. The sealing member has better sealing performance since it is arranged surrounding the first opening <NUM>.

In some embodiments, the sealing groove <NUM> may be arranged on an inner surface of the upper cover body <NUM>, and the sealing member is disposed in the sealing groove <NUM> of the upper cover body <NUM>. When the first connector <NUM> passes through the first opening <NUM>, the first connector tightly abuts the sealing member from bottom to top to realize the sealing between the first connector <NUM> and the box <NUM>. The material of the sealing member may be nitrile rubber, silica gel, nylon, or the like.

In some embodiments, the first connector <NUM> and the box <NUM> may be hermetically connected in other manners.

The first connector <NUM> and the second connector <NUM> are guided to be butted with each other by the mating of the first guiding parts <NUM> and the second guiding parts <NUM>, which could improve accuracy of the butting between the first connector <NUM> and the second connector <NUM>.

The first guiding part <NUM> is a guiding sleeve, and the second guiding part <NUM> is a guiding pillar.

For example, the substrate <NUM> and the support <NUM> are connected through an elastic member (not shown), and the extension, compression or torsion of the elastic member allows the second connector <NUM> to have a certain floating range relative to the support <NUM>, which avoids the case that the second connector <NUM> and the battery <NUM> cannot be accurately butted in place caused by manufacturing or mounting errors during the butting process between the second connector <NUM> and the battery <NUM>. The floating mounting of the second connector <NUM> to the support <NUM> may also enable the first guiding parts <NUM> and the second guiding parts <NUM> to be mated in a case when the first connector <NUM> and the second connector <NUM> have a certain mounting or manufacturing error, realizing an accurate butting between the first connector <NUM> and the second connector <NUM>.

The direction of the position at which the battery <NUM> is butted with the second connector <NUM> is different according to a different orientation of the second connector <NUM>. For example, in some embodiments, the support <NUM> is connected to the bottom of the vehicle body, and the second connecting end <NUM> is disposed to face the battery <NUM> along a direction of gravity, so that the battery <NUM> may be butted with the second connector <NUM> along a direction opposite to the direction of gravity to realize an electrical connection between the battery <NUM> and the second connector <NUM>. In this way, a damage to the first connector <NUM> and/or the second connector <NUM> due to the gravity of the battery <NUM> may be avoided and the use of the battery <NUM> or the power consumption device <NUM> may not be affected. During the mounting of the battery <NUM>, it is only necessary to push the battery <NUM> moving along a direction opposite to the direction of gravity, so that the first connector <NUM> can be butted with the second connector <NUM>, which is convenient and quick.
