[0034] like Figure 1 As shown, a schematic diagram of the overall structure of a battery structure is provided; Figure 2 As shown, a schematic diagram of the decomposition structure of a battery structure is provided, such as Figure 3 As shown, a schematic diagram of the structure of a main battery pack is provided; Figure 4 As shown, a schematic diagram of the structure of a secondary battery pack is provided.

[0035] In one embodiment, if Figure 1-4 As shown, the battery structure includes: a main battery pack 1 and a secondary battery pack 2, wherein the main battery pack 1 and the secondary battery pack 2 are used to be arranged at both ends of the handle controller, the secondary battery pack 2 and the main battery pack 1 are connected in parallel through a first wire 3, and the main battery pack 1 is provided with a power interface 5 for electrically connecting to the handle controller.

[0036] Preferably, the main battery pack 1 and the auxiliary battery pack 2 are arranged on the handle portion of the handle controller so that the weight on both sides of the handle controller is balanced.

[0037] It is understandable that only one battery cell may be provided in the main battery pack 1, or multiple battery cells may be provided in the main battery pack 1, and the multiple battery cells may be connected in series and / or in parallel as needed. Only one battery cell may be provided in the secondary battery pack 2, or multiple battery cells may be provided in the secondary battery pack 2. The number of battery cells in the secondary battery pack 2 and the main battery pack 1 may be the same, or the number of batteries in the secondary battery pack 2 and the main battery pack 1 may be different. Preferably, the number of battery cells in the secondary battery pack 2 is the same as the number of battery cells in the main battery pack 1, and the secondary battery pack 2 is connected in parallel with the main battery pack 1. The secondary battery pack 2 transmits the signal of the secondary battery pack 2 to the main battery pack 1 through the first wire 3, and is connected to the handle controller through the power interface 5 of the main battery pack 1 to power the handle controller.

[0038] The battery structure of this embodiment divides the battery pack in the controller into two parts, which are respectively arranged at the two ends of the controller. The auxiliary battery pack 2 transmits the signal to the main battery pack 1. The main battery pack 1 is connected to the power end of the controller to power the controller. The battery structure of the controller of the utility model not only adapts to the shape of the handle and fully utilizes the space of the controller, but also ensures the battery capacity. By balancing the weight on both sides of the controller, the stability of the controller is guaranteed and the user comfort is improved.

[0039] In one embodiment, if Figure 1-4 As shown, on the basis of the above embodiment, the main battery pack 1 includes: a main battery group 11 and a main circuit board assembly 12, the main circuit board assembly 12 includes: a main circuit board 121 and nickel sheets fixed at both ends of the main circuit board 121, the main battery group 11 is fixed between the nickel sheets of the main circuit board assembly 12, and the battery cells of the main battery group 11 are electrically connected to the nickel sheets of the main circuit board assembly 12;

[0040] The secondary battery pack 2 includes: a secondary battery group 21 and a secondary circuit board assembly 22, the secondary circuit board assembly 22 includes: a secondary circuit board 221 and nickel sheets fixed at both ends of the secondary circuit board 221, the secondary battery group 21 is fixed between the nickel sheets of the secondary circuit board assembly 22, and the battery cells of the secondary battery group 21 are electrically connected to the nickel sheets of the secondary circuit board assembly 22;

[0041] The main circuit board 121 is provided with an interface for connecting the first wire 3 , and the auxiliary circuit board 221 is provided with an interface for connecting the first wire 3 .

[0042] The nickel sheet can be fixed on the circuit board by welding, and the battery cells of the battery pack can be connected in series or in parallel through the circuit pattern of the circuit board by connecting the nickel sheets respectively. The battery cells of the battery pack can also be connected in series or in parallel through the nickel sheets.

[0043] It is understandable that according to the arrangement of components and circuit patterns on the main circuit board 121 and the auxiliary circuit board 221, the main circuit board 121 should at least include a battery control chip for controlling the power supply of the handle controller, and components such as resistors and switches connected to the battery control chip. The circuits on the main circuit board 121 should at least include a circuit between the interface connecting the first wire 3 on the main circuit board 121 and the power interface 5, a circuit between the nickel sheet on the main circuit board 121 and the power interface 5, and a circuit between the battery control chip and the resistors, switches and various interfaces.

[0044] The auxiliary circuit board 221 should at least be provided with a circuit between the nickel sheet on the auxiliary circuit board 221 and the interface of the first wire 3 .

[0045] The battery structure of this embodiment has a circuit board set in the battery pack, and the circuit board and nickel sheet are used to transmit the signals of the battery cells of the battery pack to the handle controller. The circuit board can ensure the quality and integrity of signal transmission, and the interface on the circuit board makes the connection and maintenance of the wires more convenient.

[0046] In one embodiment, if Figure 5As shown, a circuit connection diagram of a battery structure is provided. On the basis of the above embodiment, a first resistor branch 13 and a second resistor branch 14 are provided on the main circuit board 121, one end of the first resistor branch 13 is connected to the positive electrode of the main battery pack 11, the other end of the first resistor branch 13 is electrically connected to the power supply end of the controller, one end of the second resistor branch 14 is connected to the negative electrode of the main battery pack 11, and the other end of the second resistor branch 14 is grounded.

[0047] Since the first wire 3 connecting the auxiliary battery pack 21 and the main battery pack 11 has resistance, when the signal output by the auxiliary battery pack 21 is transmitted to the handle controller through the first wire 3, the output current of the auxiliary battery pack 21 and the main battery pack 11 are inconsistent due to the resistance of the first wire 3. When high-rate power supply is performed, the actual voltage difference between the main battery pack 11 and the auxiliary battery pack 21 will become larger, affecting the service life of the battery. In order to avoid damage to the main battery pack 11 and the auxiliary battery pack 21, a resistance branch is set at the output end of the main battery pack 11. The resistance of the resistance branch is used to balance the resistance of the first wire 3, so as to balance the pressure difference problem of the two battery packs during high-rate discharge. Figure 5 The resistor R1 and the resistor R2 are equivalent resistances of the first wire.

[0048] The number and parameters of the resistors in the resistor branch can be set according to actual application conditions so that the voltage difference between the two battery packs is balanced.

[0049] In the battery structure of this embodiment, resistance branches are respectively set at the output ends of the main battery pack 11, and the resistance of the first wire 3 is balanced by the resistance of the resistors, so as to balance the pressure difference problem of the two battery packs in high-rate discharge, thereby improving the reliability of the battery pack.

[0051] The secondary battery pack 21 includes a third battery cell 81 , a fourth battery cell 82 , and a second fixing bracket 211 . The third battery cell 81 and the fourth battery cell 82 are fixed on two sides of the second fixing bracket 211 , respectively.

[0052] The electrodes of the battery cells on both sides of the fixed bracket may be in the same direction, or the electrodes of the battery cells on both sides of the fixed bracket may be in different directions.

[0053] As another embodiment, the battery pack may further be provided with a third battery cell 81 and a second fixing bracket 211 . It is understandable that at least two battery cells are provided in the battery pack.

[0054] In the battery structure of this embodiment, two battery cells are arranged in each battery pack, which can ensure the capacity of the battery.

[0055] In one embodiment, based on the above embodiment, the first battery cell 71 and the second battery cell 72 are respectively adhesively connected to the first fixing bracket 111 , and the third battery cell 81 and the fourth battery cell 82 are respectively adhesively connected to the second fixing bracket 211 .

[0056] It is understandable that the two battery cells can be fixed on the fixing bracket by using glue or double-sided tape.

[0057] The battery structure of this embodiment uses glue or double-sided tape to fix the two battery cells on the fixing bracket to avoid direct contact between the battery cells, thereby ensuring the stability and safety of the battery pack structure.

[0058] In one embodiment, if Figure 1-4 As shown, on the basis of the above embodiment, a first positive nickel sheet 91 and a first negative nickel sheet 92 are fixedly welded to one end of the main circuit board 121, a first common nickel sheet 93 is fixedly welded to the other end of the main circuit board 121, the positive electrode of the first battery cell 71 is in contact with and connected to the first positive nickel sheet 91, the negative electrode of the first battery cell 71 is in contact with and connected to the first common nickel sheet 93, the positive electrode of the second battery cell 72 is in contact with and connected to the first common nickel sheet 93, and the negative electrode of the second battery cell 72 is in contact with and connected to the first negative nickel sheet;

[0059] A second positive nickel sheet 61 and a second negative nickel sheet 62 are fixedly welded to one end of the auxiliary circuit board 221, and a second common terminal nickel sheet 63 is fixedly welded to the other end of the auxiliary circuit board 221.

[0061] The battery structure of this embodiment utilizes nickel sheets to form a series structure between the battery cells of the battery pack, and then connects two series-connected battery cells in parallel with another two series-connected battery cells to form a two-series and two-parallel structure to power the handle controller, which can increase the capacity and voltage, meet the voltage and capacity requirements, and provide efficient and reliable power supply for the handle controller.

[0063] It is understandable that the battery control chip of this embodiment is any battery control chip, and a switch tube can be set on the main circuit board 121. The control chip controls the power supply to the handle controller by controlling the conduction and shutdown of the switch tube.

[0064] The battery structure of this embodiment is provided with a battery control chip to detect the capacity of the battery cells in the battery pack to ensure the reliability of the battery structure.

[0067] In the battery structure of this embodiment, an insulating sheet 25 is arranged on the surface of the nickel sheet. The insulating sheet 25 forms good insulation on the surface of the battery pack to avoid accidental electric shock between the battery structure and the handle controller, thereby greatly improving the reliability of the battery structure.
