Referring to fig. 1, a schematic structural diagram of a battery assembly 100 according to a preferred embodiment of the present invention is shown, in which the battery assembly 100 includes a battery compartment 110 and a battery 120, the battery compartment 110 is electrically connected to the battery 120, and the battery 120 supplies power to components in the battery compartment 110. In order to electrically connect the battery 120 and the battery compartment 110, the housing 124 of the battery 120 has a female connection end 140, a male connection end 130 (which may be an exposed structural design) is disposed in the battery compartment 110, the battery 120 is inserted into the battery compartment 110, and the male connection end 130 is electrically connected to the female connection end 140, thereby forming a power supply circuit for the battery 120. Meanwhile, in order to realize a simpler insertion and extraction manner of the battery 120, the side surface of the battery compartment 110, especially the side surface in the radial direction thereof, is provided with the mounting opening 111, and for the mounting opening 111, it can be understood that the opening is not opened in the vertical direction or close to the vertical direction, such as the upper side, the oblique upper side, etc., of the battery compartment 110, but is opened on the pure side surface of the battery compartment 110, so that the direction in which the battery 120 enters the battery compartment 110 or is separated from the battery compartment 110 is also along the radial direction of the battery compartment 110, that is, when the battery compartment 110 is arranged in the vertical direction, the direction in which the battery 120 is mounted and separated is also the horizontal direction. And the mounting opening 111 is also configured such that the size of the mounting opening 111 matches the size of the battery 120, and the battery 120 is just in clearance fit with the inner wall of the battery compartment 110 when the battery 120 is placed in the mounting opening 111. With the above configuration, for the insertion or removal of the battery 120 from the battery compartment 110, the battery 120 is not substantially contacted with the inner wall of the battery compartment 110 during the whole insertion or removal process, and the battery compartment 110 does not affect the battery 120 and the components in the battery 120.

After the battery 120 is inserted into the mounting opening 111 and is in clearance fit with the battery compartment 110, the battery 120 is not easy to be taken out from the battery compartment 110 because there is no part for applying force between the battery 120 and the battery compartment 110, therefore, the housing 124 of the battery 120 comprises a mounting end surface 121 and a taking end surface 122, the mounting end surface 121 is a surface facing the mounting opening 111, and the taking end surface 122 is a surface of the housing 124 of the battery 120 facing away from the mounting opening 111. Therefore, when the battery 120 is inserted into the mounting opening 111, the mounting end surface 121 enters the mounting opening 111 first until the battery 120 completely enters the mounting opening 111 (i.e., the inside of the battery compartment 110), the mounting end surface 121 is attached to the inner wall of the battery compartment 110 opposite to the mounting opening 111, and the taking end surface 122 is parallel to the mounting opening 111 or is sunk into the mounting opening 111, so that the battery 120 is completely inserted into the battery compartment 110. A handle assembly 123 is disposed on the fetching end surface 122, the handle assembly 123 faces the outside of the battery compartment 110 and is connected with the battery 120, and when the handle assembly 123 is stressed, the battery 120 is driven to move together. Specifically, when the handle assembly 123 receives a pulling force in a direction opposite to the battery compartment 110, the battery 120 is taken out from the battery compartment 110 and separated therefrom.

It can be understood that, since the pulling force is in a direction opposite to the battery compartment 110, and more preferably, the direction of the force applied by the pulling force is perpendicular to the taking end surface 122, no matter the battery compartment 110 is inserted or removed, firstly the surface of the battery 120 is not in contact with the inner wall of the battery compartment 110, the surface of the battery 120 is protected from the inner wall of the battery compartment 110, and generally, components inside the battery 120, such as signal pins and electrical connection sheets in a socket, are perpendicular to the mounting end surface 121 and the taking end surface 122, the direction of the pulling force is consistent with the extending direction of the body of the internal components, and in the relative movement of the battery 120 and the battery compartment 110, the internal components are not in electrical contact with the internal components of the battery compartment 110, such as the signal pins and the electrical connection sheets, except after the battery 120 reaches the final position, there is no contact or no friction during the movement, thereby protecting the battery 120 and the components inside the battery compartment.

Compared with the prior art in which the battery assembly 100 is plugged in and out of the battery 120, the lateral plugging in and out of the battery 120 greatly reduces the meaningless contact between the battery 120 and the internal components of the battery compartment 110, thereby protecting the battery assembly 100. In addition, generally, when the battery assembly 100 is installed in an external device, such as a public bike including an electric car and a power-assisted vehicle 200, the conventional battery 120 is replaced by removing a seat installed above the battery assembly 100, so that a path for taking out the battery 120 can be separated. In the invention, the inserting and pulling direction of the battery 120 in the battery assembly 100 is always unimpeded (perpendicular to the direction of the seat above the battery assembly 100), so that the process of replacing the battery 120 is saved.

-air vents 114

At least one vent hole 114 is formed on the back shell 113, the vent hole 114 penetrates through the back shell 113 to communicate the accommodating space with the outside, on one hand, the vent hole is used for exhausting the air in the accommodating space to prevent the situation that the air in the accommodating space cannot be exhausted to abut against the battery 120 when the battery 120 is inserted into the accommodating space, on the other hand, when the handle assembly 123 is damaged (such as artificial damage or natural damage after being exposed to the outside), the pulling force applying part of the user is absent, and the battery 120 cannot be taken out from the accommodating space, the vent hole 114 can be used as a channel for the contact between the outside and the battery 120, for example, a slender element (the diameter is smaller than the vent hole 114) is used, the slender element is poked into the accommodating space from the direction of the back shell 113, and the battery 120.

In addition, the connecting male end 130 protrudes from the inner wall of the bin body 112, i.e., the inner wall of the accommodating space, and the position of the connecting female end 140 naturally corresponds to the position of the connecting male end 130. The female connection end 140 is provided at an upper portion of the battery 120 such that the battery lock 116 can extend into the interior of the battery 120.

Referring to fig. 4-5, showing the structure of the battery 120 in the battery assembly 100 in a preferred embodiment, the housing 124 of the battery 120 forms the overall contour of the battery 120, and the housing 124 is sized to be in clearance fit or interference fit with the receiving space, such that the battery 120 can be completely mounted with the battery compartment 110 without any additional external connecting elements, in addition to the housing 124, the battery 120 further includes a battery body 125, the battery body 125 is mounted in the housing 124 in a closed manner, the circuit of the battery 120 is electrically connected with the connecting female terminal 140 (e.g., via an electrical connection pad, etc.), the charge in the battery body 125 is transmitted to the connecting male terminal 130 via the circuit of the battery 120, the electrical connection pad, the connecting female terminal 140, and the connecting male terminal 130, since the connecting male terminal 130 is disposed in a protruding manner on the inner wall of the receiving space, an excessively long groove 127 having a L-shaped cross section to match the external contour of the connecting male terminal 130 is disposed above the housing 124, such that the groove 127 is in clearance fit with the connecting male terminal 130 after the battery 120 is inserted into the receiving space, and the connecting female terminal 140 is disposed at the groove 127, or the outer surface of the connecting female terminal 140 is not directly connected with the connecting male terminal 130, and the male terminal 130, the connecting groove 130 is inserted into the receiving space, and the connecting groove 130, the connecting male terminal 130 is not directly, and the male terminal 130 is inserted into the connecting groove 130, and the connecting groove 130 is inserted into the connecting groove 130, the connecting.
