Through continuous research and design, and after repeatedly trying on samples and improving, finally the utility model discloses establish and confirm utensil practical value.

Referring to fig. 1-2, an embodiment of the present invention provides a detachable battery, which includes a housing 10, at least two single batteries 20, at least one fixing bracket 30, a protection plate 40, a flexible circuit board 50, and a charging plate 60; wherein,

each of the fixing brackets 30 is detachably provided in the housing 10;

each single battery 20 of the at least two single batteries 20 is arranged side by side and at intervals, each two adjacent single batteries 20 are fixed side by side through one fixing bracket 30, and each single battery 20 is detachably connected with the corresponding fixing bracket 30;

the protection plate 40 is connected with the fixing bracket 30 and is connected with the positive and negative terminals of each unit battery 20; the protection plate 40 is provided with a discharge terminal 70;

the charging plate 60 is connected with the fixing bracket 30 and is provided with a charging interface 80;

one end of the flexible circuit board 50 is connected to the protection board 40, and the other end is connected to the charging board 60;

a discharging port 90 is formed on the housing 10 at a position corresponding to the discharging terminal 70, and a charging port 100 is formed at a position corresponding to the charging port 80.

It should be noted that, in the present embodiment, by adding the fixing bracket 30, then the single battery 20 is detachably disposed on the fixing bracket 30, and then the fixing bracket 30 is also detachably disposed in the housing 10, so that when the single battery 20 is damaged, after the housing 10 is opened and the fixing bracket 30 is taken out, the damaged single battery 20 can be detached from the fixing bracket 30 for replacement, and the whole battery does not need to be discarded.

For example, the number of the single batteries 20 is not limited, and is only larger than two, but for the convenience of understanding, the present embodiment takes two single batteries 20 as an example for illustration, that is, the number of the single batteries 20 in fig. 1 and 2 is two.

In this embodiment, the inner wall of the housing 10 is provided with a sliding groove which is engaged with the fixing bracket 30.

It should be noted that, the design of the sliding groove is to cooperate with the fixing support 30, so that the fixing support 30 and the housing 10 are detachably connected, when the fixing support 30 needs to be placed in the housing 10, only the fixing support 30 needs to slide in along the sliding groove, and similarly, when the fixing support 30 needs to be taken out from the housing 10, only the fixing support 30 needs to slide out along the sliding groove.

In this embodiment, the surface of the fixing bracket 30 contacting the single battery 20 is a clamping surface, and the shape of the clamping surface matches with the shape of the outer surface of the single battery 20.

It should be noted that, in order to make the fixing bracket 300 have the capability of fixing the single battery 20, in this embodiment, a surface of the fixing bracket 300 contacting the single battery 20 is specifically designed as a clamping surface, and since the shape of the clamping surface matches with the shape of the outer surface of the single battery 20, the fixing bracket 300 can be well attached to the outer surface of the single battery 20.

It can be understood that the arc of the clamping surface of the fixing bracket 300 in the normal state is a little smaller than the arc of the outer surface of the battery cell 20, so when the outer surface of the battery cell 20 is attached to the clamping surface of the fixing bracket 300, the clamping surface of the fixing bracket 300 is spread, and a clamping force capable of clamping the battery cell 20 is generated.

In this embodiment, the fixing bracket 30 is made of a heat conductive material.

It should be noted that, in this embodiment, besides the fixing support 30 plays a role of clamping the single battery 20 and making the single battery 20 detachable, the fixing support 30 is made of a heat conducting material, so that the fixing support also has a capability of assisting the heat dissipation of the single battery 20, that is, heat generated during the charging and discharging of the single battery 20 is transferred to the fixing support 30, thereby increasing the heat dissipation area to accelerate the heat dissipation.

In this embodiment, the clamping surface is provided with an anti-skid heat-conducting coating or anti-skid lines.

It should be noted that, as mentioned above, the fixing bracket 300, specifically, the clamping surface thereof, needs to have the capability of fixing the single battery 20, so in order to increase the connection reliability between the two, the embodiment provides an anti-skid heat-conducting coating or an anti-skid texture on the clamping surface, which can increase the friction force between the two.

In this embodiment, at least two of the unit batteries 20 are connected in parallel through nickel plates and then connected to the protection plate 40.

The protective plate 40 is also provided with a battery status indicator lamp 110;

a lamp hole 120 is formed on the housing 10 at a position corresponding to the battery status indicator lamp 110.

It should be noted that the battery status indicator 110 is a multi-color LED lamp, and the battery can emit lights with different colors when charging and discharging, so as to indicate the current status of the battery.

In this embodiment, the protection plate 40 is provided with a connection hole 130;

a connecting column 140 is arranged on the fixed bracket 30;

the connection post 140 is snapped into the connection hole 130 to connect the fixing bracket 30 and the protection plate 40.

It should be noted that, in addition to the detachable connection structure of the connection hole 130 and the connection post 140, the connection between the fixing bracket 30 and the protection plate 40 can also be detached by means of bolts or gluing.

In this embodiment, the fixing bracket 30 is provided with a slot;

the charging board 60 is clamped in the card slot.

It should be noted that the charging plate 60 may also be connected to the fixing bracket 30 by bolts or by gluing.

In the present embodiment, the housing 10 includes an upper cover 11 and a lower cover 12;

the upper cover 11 is detachably connected with the lower shell 12.
