Technical Field

[0001] This invention relates to the field of batteries, and more specifically to a battery pack and its processing method. Background Technology

[0002] Battery packs refer to those connected in series or in parallel. Parallel battery packs require each battery to have the same voltage, and the output voltage is equal to the voltage of one battery. Parallel battery packs can provide a stronger current. Series battery packs have fewer requirements. For example, patent number CN106573551A, entitled "Method for Connecting Battery Pack Batteries and Battery Pack System," discloses a method for connecting multiple battery pack batteries. However, the drawback of this patent is that it cannot adjust the number of batteries to be connected in parallel according to different usage requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a battery pack and its processing method, which can adjust the number of batteries that need to be connected in parallel according to different usage requirements.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A battery pack includes a support bracket, which has four support brackets. The four support brackets are divided into two pairs, one above the other. Each pair of two support brackets is slidably connected to two sliding brackets I. A compression spring I is fixedly connected between the sliding brackets I and the support brackets.

[0006] Four connecting brackets are slidably connected between the two pairs of support brackets, and a compression spring II is fixedly connected between the connecting brackets and the support brackets.

[0007] Each support bracket is fixedly connected to a limit plate I, and each sliding bracket I is fixedly connected to a limit plate II;

[0008] Each support bracket is rotatably connected to a storage wheel and a limiting wheel. A conductive strip is wound between the corresponding storage wheels on each pair of support brackets, and the conductive strip passes through one side of the corresponding limiting wheel.

[0009] The four connecting brackets are divided into two pairs, left and right. Two sliding brackets II are slidably connected between the two pairs of connecting brackets. A compression spring III is fixedly connected between the sliding bracket II and the connecting bracket. A mounting baffle is slidably connected between each pair of two connecting brackets. The mounting baffle is fixedly connected between the two connecting brackets by mounting screws.

[0010] Multiple batteries are placed between four support brackets, two sliding brackets I, four connecting brackets, two sliding brackets II, two mounting baffles, four limiting plates I, and four limiting plates II. The positive and negative terminals of the multiple batteries are in contact with two conductive strips, respectively.

[0011] A method for processing a battery pack, the method comprising the following steps:

[0012] Step 1: Place the copper plate between four drive rollers, which then drive the copper plate through multiple rolling rollers.

[0013] Step 2: Multiple pairs of calendering rollers are moved up and down, with the relative distance between each pair of calendering rollers gradually decreasing;

[0014] Step 3: Multiple rolling rollers roll the copper plate to form a conductive strip;

[0015] A battery pack processing device includes a processing bracket, on which four telescopic mechanisms I are fixedly connected. Each telescopic mechanism I has a drive roller rotatably connected to its telescopic end. A power mechanism I for driving the drive roller to rotate is fixedly connected to the telescopic end of the telescopic mechanism I. The power mechanism I is preferably a servo motor.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings.

[0039] like Figures 2 to 6 As shown below, the structure and function of a battery pack will be described in detail.

[0040] A battery pack includes a support bracket 11, and four support brackets 11 are provided. The four support brackets 11 are divided into two pairs, upper and lower. Two sliding brackets I 21 are slidably connected between the two support brackets 11 in each pair. A compression spring I is fixedly connected between the sliding brackets I 21 and the support bracket 11.

[0041] Four connecting brackets 41 are slidably connected between the two pairs of support brackets 11, and compression springs II are fixedly connected between the connecting brackets 41 and the support brackets 11.

[0042] Each support bracket 11 is fixedly connected to a limit plate I 12, and each sliding bracket I 21 is fixedly connected to a limit plate II 22;

[0043] Each support bracket 11 is rotatably connected to a storage wheel 31 and a limiting wheel 32. A conductive strip 33 is wound between the corresponding storage wheels 31 on each pair of support brackets 11, and the conductive strip 33 passes through one side of the corresponding limiting wheel 32.

[0044] The four connecting brackets 41 are divided into two pairs, left and right. Two sliding brackets II 44 are slidably connected between the two pairs of connecting brackets 41. A compression spring III is fixedly connected between the sliding brackets II 44 and the connecting brackets 41. A mounting baffle 42 is slidably connected between each pair of two connecting brackets 41. The mounting baffle 42 is fixedly connected between the two connecting brackets 41 by mounting screws 43.

[0045] Multiple batteries 50 are placed between four support brackets 11, two sliding brackets I 21, four connecting brackets 41, two sliding brackets II 44, two mounting baffles 42, four limiting plates I 12, and four limiting plates II 22. The positive and negative terminals of the multiple batteries 50 are in contact with two conductive strips 33 respectively.

[0046] When using, such as Figure 2 As shown, rotating the mounting screw 43 causes it to move through the thread, thus removing the mounting screw 43 from the mounting baffle 42. Both ends of the mounting baffle 42 are connected to the mounting screw 43 by threads. The mounting screw 43 presses against the connecting bracket 41. After removing the two mounting screws 43, the mounting baffle 42 is pushed to move, causing it to slide between the two connecting brackets 41. The mounting baffle 42 is then pulled out from between the two connecting brackets 41. At this point, the battery 50 is placed between the four support brackets 11, the two sliding brackets I 21, the four connecting brackets 41, the two sliding brackets II 44, the two mounting baffles 42, the four limiting plates I 12, and the four limiting plates II 22, so that the positive and negative terminals of the battery 50 contact the two conductive strips 33 respectively, thus completing the installation of the battery 50.

[0047] Furthermore, depending on different usage requirements, different numbers of batteries 50 can be placed between four support brackets 11, two sliding brackets I 21, four connecting brackets 41, two sliding brackets II 44, two mounting baffles 42, four limiting plates I 12 and four limiting plates II 22. Since the four support brackets 11 are slidably connected to each other by four sliding brackets I 21, the overall relative distance between the four support brackets 11 can be adjusted, thereby accommodating different numbers of batteries 50.

[0048] Furthermore, when the relative distance between the four support brackets 11 changes, the corresponding storage wheel 31 rotates, thereby releasing the conductive strip 33. The conductive strip 33 is a copper foil sheet, and the length of the conductive strip 33 also changes accordingly, thereby ensuring that when the number of batteries 50 changes, the positive and negative terminals of each battery 50 can contact the conductive strip 33.

[0049] Furthermore, four connecting brackets 41 are slidably connected between the four supporting brackets 11, so that the height between the four supporting brackets 11 can be adjusted. Thus, when the height of the battery 50 changes, the height between the four supporting brackets 11 changes accordingly, thereby meeting different usage needs.

[0050] Furthermore, limit plates I12 and II22 are provided, which are in contact with the upper and lower ends of the battery 50, and limit plates I12 and II22 limit the upper and lower ends of the battery 50.

[0051] Furthermore, after multiple batteries 50 are installed between four support brackets 11, two sliding brackets I 21, four connecting brackets 41, two sliding brackets II 44, two mounting baffles 42, four limiting plates I 12 and four limiting plates II 22, the mounting baffles 42 are reinserted between the two connecting brackets 41 and fixed by mounting screws 43.

[0052] like Figure 1 As shown below, the steps and functions of a battery pack processing method are explained in detail.

[0053] A method for processing a battery pack, the method comprising the following steps:

[0054] Step 1: Place the copper plate between four drive rollers 63. The four drive rollers 63 drive the copper plate to continuously pass through multiple rolling rollers 82.

[0055] Step 2: Multiple pairs of calendering rollers 82 are placed vertically and horizontally, with the relative distance between each pair of calendering rollers 82 gradually decreasing;

[0056] Step 3: Multiple rolling rollers 82 roll the copper plate to form a conductive strip 33;

[0057] like Figures 7 to 10 As shown, in order to facilitate the processing of conductive strip 33, a battery pack processing device is designed. The structure and function of the battery pack processing device are described in detail below.

[0058] A battery pack processing device includes a processing bracket 61, on which four telescopic mechanisms I 62 are fixedly connected. Each telescopic mechanism I 62 is rotatably connected to its telescopic end. A power mechanism I for driving the drive roller 63 to rotate is fixedly connected to the telescopic end of the telescopic mechanism I 62. The power mechanism I is preferably a servo motor.

[0059] Two telescopic mechanisms II 71 are fixedly connected to the processing bracket 61. Each telescopic mechanism II 71 has a hinge seat 72 fixedly connected to its telescopic end. Two swing rods I 81 are hinged to the hinge seat 72 on one side, and two swing rods II 83 are hinged to the hinge seat 72 on the other side. The two swing rods I 81 are respectively hinged to the two swing rods II 83.

[0060] Multiple calendering rollers 82 are rotatably connected to both swing rods I 81. A power mechanism II for driving the calendering rollers 82 to rotate is fixedly connected to the swing rods I 81. The power mechanism II is preferably a servo motor.

[0061] In use, place the copper plate between the four drive rollers 63 and start the telescopic mechanism I 62. The telescopic mechanism I 62 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I 62 drives the drive rollers 63 to move, so that the four drive rollers 63 move closer to each other and the four drive rollers 63 squeeze and clamp the copper plate.

[0062] When the power mechanism I is started, the output shaft of the power mechanism I begins to rotate. The output shaft of the power mechanism I drives the drive roller 63 to rotate. When the drive roller 63 rotates, it drives the copper plate to move, so that the copper plate continuously passes between multiple rolling rollers 82.

[0063] When power mechanism II is activated, its output shaft begins to rotate, driving the calendering roller 82 to rotate. Simultaneously, telescopic mechanism II 71 is activated. Telescopic mechanism II 71 can be a hydraulic cylinder or an electric push rod. The telescopic end of telescopic mechanism II 71 drives the hinge seat 72 to move, which in turn drives the swing rod II 83 to move. The swing rod II 83 then drives the swing rod I 81 to move, which in turn drives multiple calendering rollers 82 to move up and down. Figure 8 As shown, the relative distance between each pair of rolling rollers 82 gradually decreases, and multiple pairs of rolling rollers 82 continuously roll and press the copper plate, thereby forming a conductive strip 33 on the copper plate.
