Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a combined battery. Background Art

[0002] A battery combination is a battery assembly method in which multiple batteries are combined and connected in series or in parallel. For details, please refer to the Chinese patent with announcement number CN220106665U, which discloses a battery combination. The battery combination includes a plurality of batteries and a battery box for placing the batteries. The battery box is provided with a plurality of mounting holes for placing the batteries. The top and bottom of the battery box are provided with covers to prevent the batteries from escaping from the battery box. When all the batteries are loaded into the battery box, the batteries are connected in series or in parallel using wires.

[0003] The total power of the above-mentioned battery assembly depends on the number of batteries, that is, the number of mounting holes set on the battery box, which results in that the battery assembly can only be applied to electrical devices with power requirements that match it, but cannot be applied to electrical devices with other power requirements. Therefore, the battery assembly has the problem of poor adaptability. Utility Model Content

[0004] In view of the shortcoming of the existing battery assembly that the maximum power of the battery assembly cannot be adjusted by increasing or decreasing the number of batteries, the purpose of the utility model is to provide a combined battery that can adjust the maximum power by increasing or decreasing the number of batteries.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A combined battery includes at least two battery units that can be spliced ​​with each other. The battery unit includes a mounting seat and a battery body clamped on the mounting seat. Conductors that are respectively conductively connected to the positive and negative electrodes of the battery body are arranged at both ends of the mounting seat. A movable conductive part and a connecting part that can be used for conductive connection between the movable conductive parts on adjacent battery units and the conductor are movably arranged on the conductor.

[0007] By adopting the above scheme, the user can select a corresponding number of battery cells according to the power demand of the electrical equipment, and then splice the battery cells. After the splicing is completed, the movable conductive parts on each battery cell can be conductively connected to the connecting parts on one of the adjacent battery cells, so that each battery cell forms a complete combined battery. Compared with the existing battery combination, the combined battery in this scheme can adapt to electrical equipment with different power demands, effectively increasing the scope of application of the combined battery.

[0008] Preferably, the movable conductive part includes a conductive sheet, a conductive pivot part is provided on the conductor for the conductive sheet to rotatably sleeve thereon, the connecting part is a guide column protruding from the conductor, and a slot is provided on the conductive sheet which can be engaged with the guide column on the adjacent battery unit after rotation.

[0009] By adopting the above scheme, the guide pillar can conduct electricity, and the adjacent units can be conductively connected after the conductive sheet and the guide pillar are clamped together. The clamping operation process of the two is simple, and the guide pillar and the conductor can be integrally formed, which is easy to produce.

[0010] Preferably, the movable conductive part includes a conductive sheet, a conductive pivot part is provided on the conductor for the conductive sheet to rotatably sleeve thereon, the connecting part is a first bolt, the conductive sheet is provided with a slot which can be engaged with the first bolt on the adjacent battery unit after rotation or a through hole for the first bolt to pass through along its axial direction, and a first threaded hole which cooperates with the bolt is provided on the conductor.

[0011] Preferably, the first bolt is made of conductive material or insulating material. When the first bolt is made of conductive material, after the first bolt is engaged with the first threaded hole, the conductive sheet contacts the conductor or engages with the first bolt; when the bolt is made of insulating material, the first bolt is screwed into the first threaded hole until the conductive sheet is pressed against the conductor.

[0012] Compared with the method of using the guide column as a connecting member in the above-mentioned solution, this solution uses the first bolt as a connecting member. Its advantage is that no matter whether the first bolt is conductive or not, the first bolt can prevent the conductive sheet from detaching from the conductor after being tightened, making the connection between the battery cells more secure.

[0013] Preferably, the conductive pivot joint comprises a second bolt, the conductive sheet is sleeved on the second bolt, and a second threaded hole matching with the second bolt is provided on the conductor.

[0014] With the above solution, the conductive sheet is directly mounted on the second bolt, which is prone to deflection. To prevent the conductive sheet from contacting the conductors on other battery cells due to deflection, thereby destroying the connection between the battery cells, the user can gradually tighten the second bolt until the conductive sheet needs to overcome a certain friction force before it can rotate. This can reduce the probability of the above situation occurring.

[0015] Preferably, a damping component for increasing the rotation resistance of the conductive sheet is provided on the second bolt.

[0016] Preferably, the damping component comprises a spring sleeved on the second bolt, and two ends of the spring are elastically in contact with the large end of the second bolt and the conductive sheet respectively.

[0017] By adopting the above solution, the spring can overcome a certain resistance when the conductive sheet rotates, so the user does not need to frequently check the tightening state of the second bolt, which is more convenient to use.

[0018] Preferably, a slot having an opening smaller than the bottom and passing through both ends of the mounting seat is provided on one side wall of the mounting seat, and an insert strip which can be embedded in the slot of an adjacent mounting seat is provided on the side wall of the mounting seat facing away from the slot.

[0019] Preferably, a charging interface capable of charging the battery or supplying power to an electrical device through the battery is provided on the outer ring wall of the battery body.

[0020] The utility model adopts the above technical scheme, which has significant technical effects: the user can select a corresponding number of battery cells according to the power demand of the electrical equipment, and then splice the battery cells. After the splicing is completed, the movable conductive parts on each battery cell can be conductively connected with the connecting parts on one of the adjacent battery cells, so that each battery cell forms a complete combined battery. Compared with the existing battery assembly, the combined battery in this scheme can adapt to electrical equipment with different power demands, effectively increasing the scope of application of the combined battery.
