Description

Technical Field

[0001] This utility model relates to the field of battery technology, and specifically to a battery structure. Background Technology

[0002] A battery is a device that directly converts chemical energy into electrical energy through an electrochemical reaction. It can be used individually, such as with common button batteries or AAA batteries, or in combination, such as in electric vehicle batteries. When used in combination, multiple batteries (also called cells) are placed in a mounting frame, with a circuit board on top of the frame. Adjacent cells are connected by metal parts, with both ends of the metal parts connected to the circuit board and the mounting frame, respectively. However, replacing cells in a combination is inconvenient. First, the mounting frame consists of two parts, left and right, each with limiting positions on both ends of the cells. Therefore, replacing a cell requires disassembling both parts before replacing the cell. Second, before disassembling the two parts, the circuit board and metal parts must be removed. It's clear that replacing a single cell is quite troublesome, essentially requiring the removal of all components connected to the mounting frame, as well as the mounting frame itself.

[0045] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0046] like Figures 1-12 As shown, a battery structure includes a mounting frame 1 and several battery cells 2. The mounting frame 1 has several through holes for connecting the left and right sides, and one end of each through hole is an inlet. The battery cells 2 enter through the inlet and are located inside the through hole. A circuit board 3 is provided on the top of the mounting frame 1. A first metal sheet 4 and a second metal sheet 6 are respectively connected to both ends of the battery cells 2. The first metal sheet 4 is located outside the inlet, and a detachable baffle 5 is provided outside the first metal sheet 4.

[0047] Therefore, in actual use, the battery cell 2 can be installed and removed from the side through the inlet of the through hole, and the baffle 5 and the mounting bracket 1 are connected by screws, so installation and disassembly are relatively convenient.

[0048] The structure of the mounting bracket 1 varies. It can be integrally formed, or it can include a first mounting bracket 11 and a second mounting bracket 12, with the first mounting bracket 11 and the second mounting bracket 12 connected by screws. When the mounting bracket 1 includes a first mounting bracket 11 and a second mounting bracket 12, the first mounting bracket 11 and the second mounting bracket 12 are respectively provided with a first through hole 111 and a second through hole 121, and the first through hole 111 and the second through hole 121 are combined to form the through hole.

[0049] Meanwhile, the structure of the baffle 5 is as follows: First, several battery cells 2 are evenly divided into multiple groups, each group includes at least two battery cells 2, and the two battery cells 2 form a line. Moreover, there are multiple baffles 5, and each baffle 5 corresponds to two adjacent groups, that is, the baffle 5 covers the outside of the two adjacent groups.

[0050] Therefore, in actual use, there are multiple baffles 5 instead of a single piece. This allows baffles 5 to be removed only when a faulty battery cell 2 is found, thus avoiding impact on other battery cells 2. Furthermore, there is a limiting structure between the mounting bracket 1 and the baffles 5. Specifically, the mounting bracket 1 has a second protrusion 13 on its outer side, and the baffles 5 have a second snap-fit ​​hole 51 corresponding to the second protrusion 13. Thus, the connection is achieved by the matching of the second protrusion 13 and the second snap-fit ​​hole 51, which limits the position of the baffles 5, facilitating screw installation.

[0051] like Figures 1-12 As shown, the assembly and disassembly of the metal sheet have multiple embodiments, and as... Figure 3 As shown, in Embodiment 1, the first metal sheet 4 and the circuit board 3 are detachably connected, and the second metal sheet 6 can be cut off and connected to the circuit board 3, and the second metal sheet 6 is located on the outside of the other end of the through hole.

[0052] Therefore, in actual use, when replacing the battery cell 2, first remove the baffle 5 and separate the first metal piece 4 and the circuit board 3. Then, by cutting the second metal piece 6, the restriction between the second metal piece 6 and the mounting bracket 1 is released. At this time, pull out the battery cell 2 with the metal piece to replace the battery cell 2.

[0053] The first metal sheet 4 and the circuit board 3 are detachably connected by screws. The specific structure is as follows: First, the first metal sheet 4 includes a metal sheet 41, and the top of the metal sheet 41 is provided with a connecting part 411 for screw connection with the circuit board 3, and the bottom of the metal sheet 41 is provided with a connecting part 412 for screw connection with the mounting bracket 1.

[0054] Therefore, in actual use, the use of screw connections makes disassembly and assembly very convenient, requiring only the screws to be unscrewed or screwed in.

[0055] Furthermore, the first metal sheet 4 also includes a second metal sheet 42, which is located between two first metal sheets 41. The bottom of the second metal sheet 42 is provided with a third connecting part 421 for screw connection with the mounting bracket 1, and the third connecting part 421 is connected to the second connecting part 412 via a connecting plate 43.

[0056] At the same time, the second metal sheet 6 can be cut into metal sheet four 61, and metal sheet four 61 includes at least two connecting pieces four 611 and a connecting segment four 612 located between the two connecting pieces four 611. The connecting pieces four 612 correspond one-to-one with the battery cell 2, and the connecting segment four 612 is used to connect the two connecting pieces four 61 and can be cut.

[0057] Therefore, in actual use, by cutting the connecting piece 61, the restriction between the second metal piece 6 and the mounting bracket 1 is released, which makes it easier to pull out the battery cell 2 with the metal piece.

[0058] Secondly, the second metal sheet 6 can be cut off and can also be threaded to the circuit board 3. That is, the top and bottom of the metal sheet 61 are respectively provided with connecting part 613 and connecting part 614, which are used to thread to the circuit board 3 and the mounting bracket 1 respectively. There is also a metal sheet 62 and a mounting plate 63. The bottom of the metal sheet 62 is provided with connecting part 621, and the mounting plate 63 connects the connecting part 621 and the connecting part 621.

[0059] Therefore, in actual use, the use of screw connections makes disassembly and assembly very convenient, requiring only the screws to be unscrewed or screwed in. Furthermore, the second metal plate 6 may also have a metal plate 7 65, and the top of the metal plate 7 65 is provided with a connecting part 9 651 for threaded connection with the circuit board 3.

[0060] like Figure 5 and Figure 9 As shown, a limiting structure is provided at the other end of the through hole to limit the position of the battery cell 2. The structure can be varied and can be as follows: Figure 5 As shown, a stop 122 is provided on the outer side of the other end of the through hole. The stop 122 limits the movement of the battery cell 2, and since it is located between two adjacent second metal sheets 6, it also serves to isolate and limit movement. Or as... Figure 9 As shown, a baffle 5 is provided on the outer side of the other end of the through hole, which limits the movement of the battery cell 2.

[0061] Moreover, as Figure 4As shown, the mounting bracket 1 also has a limiting structure for the first metal piece 4, and this limiting structure is also adapted to the baffle 5. That is, a protrusion 14 is provided on the outer side of the mounting bracket 1, and a snap-fit ​​hole 46 is opened on the first metal piece 4 corresponding to the protrusion 45, and a snap-fit ​​hole 52 is opened on the baffle 5 corresponding to the protrusion 45. Therefore, in actual use, the connection and limiting are achieved by the adaptation of the protrusion 14 to the snap-fit ​​hole 46 and the protrusion 14 to the snap-fit ​​hole 52. In addition, a limiting block 15 is provided on the outer side of the inlet of the mounting bracket 1, and the limiting block 15 is located between two adjacent first metal pieces 4, thereby playing the role of isolation and limiting.

[0062] Example 2 is basically the same as Example 1, except that the structure of the first metal sheet 4 is different. The first metal sheet 4 can be cut and connected to the circuit board 3. Therefore, in actual use, when replacing the battery cell, the baffle 5 is removed first, and then the first metal sheet 4 and the second metal sheet 6 are cut. At this time, the battery cell 2 with the metal sheet is pulled outward to replace the battery cell 2.

[0063] The first cuttable metal sheet 4 is a metal sheet 41, and the metal sheet 41 includes at least two connecting pieces 413 and a connecting segment 414 located between the two connecting pieces 413. The connecting pieces 413 correspond one-to-one with the battery cell 2, and the connecting segment 414 is used to connect the two connecting pieces 413 and can be cut.

[0064] Therefore, in actual use, a single battery cell 2 can be replaced. That is, for a faulty battery cell 2, the corresponding connecting piece 413 and the corresponding connecting piece 611 can be directly cut off, so that the battery cell 2 with the metal piece can be replaced. Thus, a single battery cell 2 can be replaced to avoid affecting other battery cells 2.

[0065] Meanwhile, the corresponding metal sheet 42 also includes a connecting piece 2 and a connecting segment 2, and the connection between the first metal sheet 4 and the circuit board 3 can be welding or other connection methods. Alternatively, it can be a screw connection as in Embodiment 1. Therefore, when Embodiment 2 and Embodiment 1 are combined, it becomes Embodiment 3, with the specific structure being: the first metal sheet 4 can be cut off and is detachably connected to the circuit board 3, and the second metal sheet 6 can be cut off and connected to the circuit board 3, with the second metal sheet 6 located on the outer side of the other end of the through hole. Therefore, in actual use, the structure of Embodiment 3 includes various disassembly structures, thus having a wider range of applications.

[0066] Furthermore, in Embodiment 3, the second metal sheet 6 can be cut and can also be detachably connected to the circuit board 3, i.e., connected by screws, thereby facilitating installation and disassembly.

[0067] Example 4 is basically the same as Example 1, except that the structure of the second metal sheet 6 is as follows: Figure 10 As shown, the first metal sheet 4 is detachably connected to the circuit board 3, and the second metal sheet 6 is detachably connected to the circuit board 3. The second metal sheet 6 is located between the battery cell 2 and the mounting bracket 1, and the second metal sheet 6 is movable within the mounting bracket 1.

[0068] Therefore, in actual use, when replacing cell 2, first remove the baffle 5 and separate the first metal piece 4 from the circuit board 3. Then, separate the second metal piece 6 from the circuit board 3. At this point, pull out the cell 2 with the metal piece to replace the cell 2. The separable connection is a screw connection, and the connecting part of the metal piece is bendable, so that after separation and bending, interference with the circuit board 3 can be avoided during movement.

[0069] The structure related to the movement of the second metal sheet 6 is as follows: First, the second metal sheet 6 is connected to the battery cell 2 located in the same group and is connected to the through hole of the same group. The top of the mounting bracket 1 is provided with an opening that is connected to the through hole, and the opening is used for the movement of the second metal sheet 6 and connection with the circuit board 3.

[0070] Therefore, in actual use, the through holes and openings provide space for the second metal sheet 6 to move. Furthermore, because the through holes are connected, the protrusion 14 mentioned in section one is not present. Corresponding to mounting bracket 11 and mounting bracket 2 12, the through holes 111 and 121 of the same group of battery cells 2 are connected, and the tops of mounting bracket 11 and mounting bracket 2 12 are respectively provided with openings 112 and 123, which together form the opening.

[0071] Moreover, in this embodiment, the first metal sheet 4 and the second metal sheet 6 can also be cut off, so after being pulled outward, the individual battery cell 2 can be separated by cutting off.

[0072] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. However, this utility model is not limited to the above embodiments; therefore, various changes and modifications can be made without departing from the principles and scope of this utility model, and all such changes and modifications fall within the scope of the claimed utility model.
