[0002] With the development of new energy technology, batteries are widely used in electrical equipment, such as mobile phones, laptops, electric vehicles, electric cars, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes and electric tools, etc.

[0003] Due to the limitation of battery capacity, electrical devices need to be charged frequently, and charging takes time, affecting the user experience. Utility Model Content

[0004] In view of the above problems, the present application provides a battery and an electrical device that can improve the battery replacement efficiency.

[0005] On the one hand, an embodiment of the present application provides a battery. The battery includes a housing, a battery system management module, a positioning and navigation module, and a wiring harness. An installation groove is provided on the outside of the housing. At least part of the battery system management module is located in the housing. The positioning and navigation module is arranged in the installation groove. The wiring harness passes through the housing and electrically connects the battery system management module and the positioning and navigation module.

[0006] In the above scheme, the positioning and navigation module is arranged in the installation groove outside the box to reduce the shielding effect of the box on the positioning and navigation module, thereby improving the signal accuracy of the positioning and navigation module and improving the battery replacement efficiency.

[0007] In some embodiments, the box includes a first box and a second box covering the first box, the first box is made of metal, the second box is made of non-metallic material, and the positioning and navigation module is disposed on the first box.

[0008] In the above solution, by setting the positioning and navigation module on the first box made of metal material, the first box can achieve shielding effect, reduce signal interference between the positioning and navigation module and the components in the box, and improve the reliability of the positioning and navigation module.

[0009] In some embodiments, the first box is used to support the battery cells, and the side of the second box facing away from the first box is used to connect with the connecting component in the electrical device.

[0010] In the above scheme, by connecting the second box to the connecting component in the electrical device, the distance between the positioning and navigation module and the connecting component in the electrical device is increased, thereby reducing the shielding effect of the connecting component or other components in the electrical device on the positioning and navigation module, thereby improving the reliability of the positioning and navigation module.

[0011] In some embodiments, the positioning and navigation module is located on at least one side of the first box along the length direction.

[0012] In the above solution, the positioning and navigation module is arranged on one or more sides of the first box along the width direction to improve the arrangement flexibility of the positioning and navigation module and reduce the possibility of interference between the positioning and navigation module and other components.

[0013] In some embodiments, the first box body includes a first side surface and a second side surface that intersect and are adjacent to each other, the first side surface is provided with a mounting component, the mounting component is at least partially embedded in the first side surface, and the mounting groove is located on the second side surface.

[0014] In the above scheme, by providing a mounting part, the number of batteries in the electrical device can be increased while the connection strength between multiple batteries can be improved, so as to reduce the space occupied by the batteries in the electrical device and improve the integration of the batteries. By arranging the mounting part and the positioning and navigation module on the first side and the second side, the possibility of the positioning and navigation module being blocked by other batteries is reduced, thereby reducing the possibility of the positioning and navigation module being shielded by the housing of other batteries, thereby improving the reliability of the positioning and navigation module and improving the efficiency of battery replacement.

[0015] In some embodiments, the battery further includes a pressure relief mechanism, and the pressure relief mechanism and the positioning and navigation module are located on the same side of the box and are spaced apart.

[0016] In the above solution, by arranging the pressure relief mechanism and the positioning and navigation module on the same side, the area occupied by the pressure relief mechanism and the positioning and navigation module in the battery is reduced, thereby improving the integration of the battery.

[0017] In some embodiments, the battery further includes a protective shell connected to the box body, and the protective shell at least covers the wiring harness.

[0018] In the above scheme, the protective shell can be used to protect the wiring harness, reducing the possibility of the wiring harness being damaged by external moisture, debris or human factors, resulting in a short circuit in the positioning navigation module and the battery system management module.

[0019] In some embodiments, the material of the protective shell includes non-metallic material to reduce the impact of the protective shell on the shielding information generated by the positioning and navigation module, thereby protecting the positioning and navigation module and the battery system management module circuit and improving the positioning accuracy of the positioning and navigation module.

[0020] In some embodiments, a gap is provided between the positioning navigation module and the bottom wall of the mounting groove, and a mounting hole is provided on the bottom wall. The mounting hole and the gap are spaced apart, and the wiring harness passes through the box body through the mounting hole. A portion of the protective shell covers the mounting hole, and another portion of the protective shell is arranged in the gap.

[0021] In the above scheme, a part of the protective shell covers the mounting hole to cover the entire wiring harness, and another part of the protective shell is arranged in the gap, so that the other part of the protective shell is located between the positioning and navigation module and the bottom wall, so that the positioning and navigation module can limit the protective shell, thereby reducing the possibility of the protective shell falling due to vibration or other impact forces during the use of the electrical device.

[0022] In some embodiments, the protective shell includes a mounting portion, the mounting portion is disposed in the gap, and the mounting portion is detachably connected to the bottom wall.

[0023] In the above scheme, the protective shell can be fixed together with the bottom wall through the mounting part. When the positioning and navigation module is not removed, the mounting part of the protective shell is blocked by the positioning and navigation module, which increases the difficulty of disassembly between the mounting part and the bottom wall, thereby reducing the possibility of the protective shell being disassembled due to human factors and causing the wiring harness to be damaged, thereby improving the anti-dismantling performance of the protective shell.

[0024] In a second aspect, an embodiment of the present application provides an electrical device, comprising a battery in any of the aforementioned embodiments, and the battery is used to provide electrical energy.

The number of pressure relief mechanisms 60 can include multiple ones. The positioning and navigation module 30 can be located in the central area of ​​the second side surface P2, and the pressure relief mechanism 60 is located on the second side surface P2 near the edge area.
