Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

When a component is considered to be "set" on another component, it can be directly set on the other component or there may be an intermediate component present simultaneously.

They are used only for the purpose of describing the present invention and are not intended to indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of the present invention.

[0065] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0066] This invention provides a clip-on busbar, a cell bracket, a bracket assembly, a bracket module, and a battery, suitable for applications involving solderless installation and fixation of individual battery cells. It effectively solves the problems of difficult positioning and inconvenient assembly / disassembly of cylindrical battery cells.

[0067] As in Examples 1 and 2, the following describes various embodiments of the card-mounted busbar, cell bracket, bracket assembly, bracket module, and battery of the present invention with reference to the accompanying drawings.

[0068] Example 1

[0069] See Figure 1 and Figure 2 This embodiment provides a battery, including a support assembly 200 and a plurality of individual battery cells 100 installed in the support assembly 200.

[0070] First, the battery cell 100 will be introduced. The entire steel shell of the battery cell 100 is the negative electrode, and the electrode post at the end face of the steel shell is the positive electrode.

[0071] Next, the support assembly 200 will be described. In this embodiment, the support assembly 200 includes a plurality of stacked cell supports 2001, and a support top cover 2002 located above the topmost cell support 2001.

[0072] See Figure 3 The battery cell support 2001 includes a support body 1 with a battery cell receiving slot 101, a clip-on busbar 2 used as a negative busbar, and an abutment busbar 3 used as a positive busbar.

[0073] The snap-fit ​​busbar 2 is fixed to the bottom of the cell receiving slot 101. Further, the snap-fit ​​busbar 2 is formed by bending a straight metal part. Specifically, the snap-fit ​​busbar 2 is bent to form a plurality of sequentially arranged cell clamping parts 201.

[0074] In this embodiment, the cell clamping part 201 is arc-shaped to form a cell clamping groove 2011 for the cylindrical cell unit 100 to be inserted into, thereby abutting against and electrically connecting with the circumferential surface of the steel shell of the cell unit 100. In some other embodiments, the cell clamping part 201 can also be adapted to the specific shape of the cell unit 100.

[0075] Correspondingly, the bottom of the cell receiving groove 101 is also formed with several semi-circular grooves to fit with each cell clamping part 201. Further, the bottom surface of the bracket top cover 2002 is provided with several top cover semi-circular receiving grooves 2002a to accommodate each of the topmost cell units 100. The bottom surfaces of all bracket bodies 1 except the bottommost bracket body 1 are provided with several bracket semi-circular receiving grooves 102 for accommodating each of the next layer of cell units 100.

[0076] The abutting busbar 3 is fixed on the wall of the cell receiving groove 101 and is positioned opposite to the cell terminals of each cell 100 that is inserted into the snap-fit ​​busbar 2.

[0077] Furthermore, the snap-fit ​​busbar 2 and the abutment busbar 3 can be fastened to the bracket body 1 with fasteners, or they can be fixed to the bracket body 1 by means of in-mold injection molding, etc. This embodiment does not limit this.

[0078] When it is necessary to insert a single cell 100 into the cell bracket 2001, the single cell 100 can be directly inserted horizontally into the cell slot 2011. After the single cell 100 is inserted into the cell slot 2011, the terminal of the single cell 100 abuts against and is electrically connected to the abutting bus 3, and the steel shell of the single cell 100 abuts against and is electrically connected to the snap-fit ​​bus 2. At this time, all the single cells 100 in the same cell bracket 2001 are connected in parallel through the abutting bus 3 and the snap-fit ​​bus 2 to form a battery pack. As long as the abutting bus 3 and the snap-fit ​​bus 2 are connected to power, the battery pack can be connected to the circuit.

[0079] When it is necessary to remove the battery cell 100, the elastic deformation force of the battery cell clamping part 201 can be overcome, and the corresponding battery cell 100 can be directly pried out, which is simple and convenient.

[0080] Therefore, the snap-fit ​​busbar 2, cell bracket 2001, bracket assembly 200 and battery provided in this embodiment do not require welding operations. The cell unit 100 can be fixed and electrically connected directly by the elastic snap-fit ​​action of the snap-fit ​​busbar 2, thus effectively solving the problems of difficult positioning and inconvenient assembly and disassembly of cylindrical cells.

[0081] Optionally, two adjacent battery cell clamping portions 201 are connected by an n-shaped guide spring 202. Further, the top of the n-shaped guide spring 202 has a pointed structure, which facilitates the insertion of the battery cell 100 into the battery cell clamping portion 201.

[0082] In this embodiment, the abutment-type busbar 3 includes a mounting part 301, an elastic part 302, and a connecting part 303 for connecting the mounting part 301 and the elastic part 302.

[0083] See Figure 4 The mounting portion 301 is fixedly attached to the first groove wall 1011 of the cell receiving groove 101. The distance from the elastic portion 302 to each individual cell 100 is smaller than the distance from the mounting portion 301 to each individual cell 100; that is, there is a deformation space 4 between the elastic portion 302 and the first groove wall 1011 of the cell receiving groove 101, allowing the elastic portion 302 to deform backward. A terminal abutment 3021 extends downward from the elastic portion 302 corresponding to the position of each cell clamping portion 201.

[0084] Furthermore, the wall opposite to the first wall 1011 in the cell receiving slot 101 is called the second wall 1012. The distance from the second wall 1012 to the terminal abutment piece 3021 is slightly smaller than the total height of the cell 100 (total height = steel shell height + terminal height). Therefore, after the cell 100 is inserted into the cell slot 2011, the end face of the cell 100 without the terminal will abut against the second wall 1012, while the end face of the terminal will abut against the terminal abutment piece 3021, causing the terminal abutment piece 3021 to deform backward. This helps to increase the holding force between the terminal abutment piece 3021 and the terminal, thereby avoiding poor contact.

[0085] See Figure 5 In this embodiment, the snap-fit ​​busbar 2 has an upwardly protruding first insertion portion 203, and the abutment-type busbar 3 has a downwardly protruding second insertion portion 304. The first insertion portion 203 is a pin, and the second insertion portion 304 is a sleeve into which the first insertion portion 203 is inserted. The first insertion portion 203 protrudes upward to the top of the bracket body 1. The bottom surface of the bracket body 1 has an upwardly extending insertion groove 104, and the second insertion portion 304 is located in the insertion groove 104. When two cell brackets 2001 are stacked, the first insertion portion 203 on the lower cell bracket 2001 will be inserted into the second insertion portion 304 on the upper cell bracket 2001, thereby completing the series connection between the two adjacent cell brackets 2001.

[0086] Furthermore, the top cover 2002 of the bracket is provided with an upper electrical connection hole 2002b for the first plug-in portion 203 of the uppermost snap-fit ​​busbar 2 to be inserted, and a lower electrical connection hole 105 for the second plug-in portion 304 of the lowermost snap-fit ​​busbar 2 to be inserted into the bottommost cell bracket 2001. The individual cell 100s within the entire bracket assembly 200 can be electrically connected via the upper electrical connection hole 2002b and the lower electrical connection hole 105.

[0087] Of course, in some other embodiments, the second insertion part 304 can also be a pin, and the first insertion part 203 can be a sleeve into which the second insertion part 304 is inserted; the top surface of the bracket body 1 is provided with a downwardly extending insertion groove 104, and the first insertion part 203 is located in the insertion groove 104; the second insertion part 304 protrudes downward to the bottom of the bracket body 1. This structural design also allows the stacked upper and lower layers of battery cell brackets 2001 to be connected in series.

[0088] In this embodiment, the positions of the first plug-in portion 203 and the second plug-in portion 304 are symmetrical about the geometric center point of the cell receiving slot 101. At this time, the upper and lower cell supports 2001 are not completely aligned. Specifically, the abutting busbar 3 in the lower cell support 2001 is located directly below the second slot wall 1012 in the upper cell support 2001. That is, the pole orientations of the upper and lower cell cells 100 are opposite (for example, if the pole of the lower cell faces left, then the pole of the upper cell faces right).

[0089] Of course, in some other embodiments, the axes of the first plug-in portion 203 and the second plug-in portion 304 may be aligned. In this case, the upper and lower cell supports 2001 are completely aligned, that is, the pole orientation of each cell cell 100 is the same.

[0090] Optional, see Figure 6 The bracket body 1 is provided with a heat dissipation channel 103 communicating with the battery cell receiving slot 101 at a position between two adjacent battery cell clamping parts 201, so as to improve the heat dissipation performance of the bracket body 1. Optionally, cool air can be blown in through the heat dissipation channel 103 or air can be drawn out through the heat dissipation channel 103, both of which can achieve the heat dissipation effect.

[0091] Furthermore, the heat dissipation channel 103 has a fan-shaped cross-sectional shape to increase the size of the heat dissipation channel 103 and enhance the heat dissipation effect.

[0092] In this embodiment, the heat dissipation channel 103 has an opening at both ends or an opening at one end. When only one end is open, the opening of the heat dissipation channel 103 is located on the side of the direct body where the abutment busbar 3 is located, and the heat dissipation channel 103 extends directly below the second groove wall 1012. This allows for effective heat dissipation for both the battery cell 100 and the two busbars.

[0093] Optionally, the bracket top cover 2002 and each bracket body 1 are provided with positioning holes 5. As long as the positioning holes 5 are aligned, the alignment operation between the bracket top cover 2002 and the top bracket body 1, as well as between two adjacent bracket bodies 1, can be completed, reducing the difficulty of alignment.

[0094] The card-mounted busbar 2, cell bracket 2001, bracket assembly 200, and battery provided in this embodiment have the following beneficial effects:

[0095] ① The battery cell 100 does not require welding. It can be fixed and electrically connected directly through the elastic snap-fit ​​action of the snap-fit ​​busbar 2 and the elastic abutment action of the abutment busbar 3. Therefore, it can effectively solve the problems of difficult positioning and inconvenient installation and disassembly of cylindrical battery cells.

[0096] Furthermore, each battery cell is 100% removable and recyclable, eliminating the need for a single, integrated package, which significantly reduces losses, saves costs, and improves economic efficiency.

[0097] ② Through the plugging action between the first plug-in part 203 and the second plug-in part 304, the upper and lower adjacent layers of battery cell brackets 2001 are electrically connected. The number of battery cell brackets 2001 can be increased or decreased as needed, which is highly flexible and expandable.

[0098] ③ The bracket body 1 is provided with a heat dissipation channel 103, which can effectively dissipate heat from the battery cell 100 and the two busbars.

[0099] Example 2

[0100] This embodiment provides a battery, including a support module and a plurality of individual battery cells installed within the support module.

[0101] See Figure 7 In this embodiment, the support module includes several support assemblies 200 provided in Embodiment 1. It should be noted that the difference between the support assembly 200 provided in this embodiment and that in Embodiment 1 is:

[0102] In this embodiment, both the bracket body and the bracket top cover 2002 of the bracket assembly 200 are provided with a positioning boss 6 on at least one side, and a positioning groove 7 that matches the positioning boss 6 is provided on the other side opposite to the positioning boss 6.

[0103] The structural arrangement of the positioning boss 6 and the positioning groove 7 facilitates the insertion connection between two adjacent bracket assemblies 200; specifically, the insertion direction between the two bracket assemblies 200 is parallel to the arrangement direction of each cell bracket 2001 in the same bracket assembly 200, that is, it is inserted in the vertical direction.

[0104] For example, the support assembly 200 is rectangular, wherein, as Figure 1 As shown, the left and right sides of the bracket assembly 200 are respectively provided with positioning grooves 7 and positioning bosses 6. At this time, multiple bracket assemblies 200 can be expanded in the left and right direction, and the heat dissipation channel 103 extends in the front and back direction without being affected.

[0105] Or, such as Figure 7 As shown, each of the two adjacent sides is provided with the positioning boss 6, and the other two adjacent sides are provided with the positioning groove 7. Therefore, the bracket assembly 200 can be inserted and engaged with another bracket assembly 200 in the vertical direction in all four directions: front, back, left, and right. Furthermore, in this case, the design of the heat dissipation channel can be eliminated.

[0106] Of course, in some other embodiments, the support assembly 200 may also be hexagonal, in which case each support assembly 200 may be plugged into six support assemblies 200. Alternatively, the support assembly 200 may also be parallelogram, triangle, or trapezoid, etc., and this embodiment does not limit this.

[0107] In this embodiment, after two adjacent bracket components 200 are inserted vertically, they can be positioned relative to each other in the horizontal direction. Optionally, the cross-sectional shape of the positioning boss 6 can be trapezoidal, regular hexagonal, or circular, etc. This embodiment does not limit this.

[0108] The bracket module and battery provided in this embodiment have the following beneficial effects:

[0109] ① The two adjacent support components 200 are inserted and matched in the vertical direction to complete the relative positioning in the horizontal direction, effectively avoiding the occurrence of relative displacement between the adjacent support components 200;

[0110] ② The bracket assembly 200 is equipped with both a positioning boss 6 and a positioning groove 7, which is conducive to standardized operation, improves the versatility of parts, and has high flexibility and strong expandability.

[0111] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0112] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
