Abstract

A wearable battery pack is provided. The wearable battery pack includes a battery pack body, a battery cell and a housing accommodating a battery cell and a wearable device capable of wearing so that the battery pack body at least be worn on a user's back. The battery pack body has a heat dissipation channel running through one side of the battery pack body to the opposite side; the side of the battery pack body which is penetrated by the heat dissipation channel is located between the back of the user and the other side when the user carries the battery pack body. The invention provides a wearable battery pack that can be carried by users. The wearable battery pack has achieved good heat dissipation performance and can be carried by users comfortably.

First claim

What is claimed is:

wherein the battery pack body comprises:
a heat dissipation channel extending from one side of the battery pack body to an opposite side, and the one side of the battery pack body, which is penetrated by the heat dissipation channel, is located between the back of the user and the opposite side when the user carries the battery pack body, and
wherein a ratio of a power capacity of the battery pack body to a total mass of the battery pack body is greater than 120 Wh/Kg.

2. The wearable battery pack according to claim 1 , wherein an extension direction of the heat dissipation channel is parallel to a length direction of the battery cell.

3. The wearable battery pack according to claim 1 , further comprising a plurality of the battery cells and wherein the plurality of the battery cells are arranged around an axis forming a cell channel, and the axis is parallel to a length direction of each of the plurality of the battery cells.

4. The wearable battery pack according to claim 1 , further comprising a plurality of the battery cells and wherein the plurality of the battery cells are arranged around an axis forming a cell channel, the cell channel being parallel to a length direction of each of the plurality of the battery cells, the heat dissipation channel passing through the cell channel.

5. The wearable battery pack according to claim 1 , wherein the housing comprises:
a first shell wall for at least forming the heat dissipation channel running through the one side of the battery pack body to the opposite side; and
a second shell wall for forming a receiving cavity for receiving the battery cell, the receiving cavity being sealed relative to the heat dissipation channel.

6. The wearable battery pack according to claim 5 , wherein the first shell wall and the second shell wall are integrally formed.

7. The wearable battery pack according to claim 1 , wherein the battery pack body comprises:
a display device configured to display a remaining power of the battery cell.

8. The wearable battery pack according to claim 1 , wherein the battery pack body comprises:
an interface device for output or input of electrical energy of the battery cell, the interface device being electrically connected with the battery cell.

9. The wearable battery pack according to claim 1 , wherein the battery pack body comprises:
a circuit board electrically connected with the battery cell so that an output electric energy of the battery cell is at a certain voltage, the circuit board having a through hole, the heat dissipation channel passing through the through hole.

10. The wearable battery pack according to claim 9 , wherein a value range of a ratio between a sum of an area of a projection surface formed by the through hole in a front-rear direction and an area of the projection surface formed by the circuit board in the front-rear direction is from 0.01 to 0.07.

11. The wearable battery pack according to claim 1 , wherein a maximum projection surface formed in a front-rear direction of the housing is defined as a first projection surface, and a ratio between a sum of an area of a projection surface formed in the front-rear direction of the heat dissipation channel and an area of the first projection surface is from 0.004 to 0.012.

12. A wearable battery pack comprising:
a battery pack body comprising a battery cell and a housing containing the battery cell;
a carrying device for wearing on a back of a user;
a first locking device formed with a first locking portion;
a second locking device formed with a second locking portion having a locked state and an unlocked state;
the second locking device locking the first locking portion in the locked state to maintain a relative positions of the first locking device and the second locking device;
wherein the first locking device is fixedly connected to the battery pack body the second locking device is fixedly connected to the carrying device, and the second locking device includes an operating portion for the user to operate to control the second locking portion so that the user can remove the battery pack body from the carrying device.

13. The wearable battery pack according to claim 12 , wherein the first locking device further comprises a first rotating portion;
the second locking device further formed with:
a second rotating portion, which rotates about an axis;
the second rotating portion combined with the first rotating portion to enable the carrying device to rotate relative to the battery pack body when the second locking portion is in the locked state.

14. The wearable battery pack according to claim 13 , wherein the second rotating portion is coupled to the first rotating portion so that when the second locking portion is in a locked state, the carrying device rotates at a preset angle relative to the battery pack body at a preset angle when the second locking portion is in a locked state.

15. The wearable battery pack according to claim 14 , wherein the first rotating portion further comprises:
a stop surface for stopping the second rotating portion enabling the second rotating portion to rotate about an axis at a preset angle.

16. A wearable battery pack comprising:
a carrying device for enabling the battery pack to be carried on a back of a user;
a plurality of battery cells for supplying electrical energy;
a battery housing including a front housing and a rear housing for combining with the front housing to form a receiving space capable of receiving the plurality of battery cells;
an elastic member, which is arranged between the front housing and the rear housing to seal a joint of the front housing and the rear housing.

17. The wearable battery pack according to claim 16 , wherein a direction of the joint of the front housing and the rear housing is parallel to a length direction of the plurality of battery cells.

18. The wearable battery pack according to claim 16 , further comprising:
a flow guide groove, which is arranged along an inner side of the battery housing to guide a water flow in a direction.

19. The wearable battery pack according to claim 18 , further comprising:
