Description

Technical Field

[0001] This utility model relates to the field of battery assembly technology, specifically to a battery structure that is easy to assemble. Background Technology

[0002] Battery assembly structure refers to the arrangement and connection of the various components inside a battery, which directly affects the battery's performance, safety, and reliability. A good battery assembly structure ensures that all parts of the battery are subjected to uniform stress during charging and discharging, reducing internal stress and thus improving battery life and safety.

[0003] Common battery modules are assembled by arranging the cells inside the assembly slot and then fixing them with side plates and end plates on both sides using bolts. However, this method has been found to cause loosening of the battery module after assembly due to the large dimensional tolerances of the cells, resulting in misalignment of the screws on the side plates and end plates. This makes it impossible to tighten the screws and fails to meet the requirements of battery assembly. Therefore, a battery structure that is easier to assemble is proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a battery structure that is easy to assemble, thereby solving the technical problem that the large tolerance of the cell size causes the battery module to loosen after assembly, resulting in misalignment of the screws on the side plate and end plate.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a battery structure that is easy to assemble, comprising:

[0008] The side plate has a battery cell inserted inside it. End plates are installed on the left and right sides of the side plate. An aluminum connecting piece is installed on the top of each battery cell. A pressure strip is installed in the middle of the top of the end plate.

[0009] The through slots are formed on the left, right and lower sides of the end plate. The upper left and right sides of the through slots are each equipped with a first spring piece, and the lower through slots are each equipped with a second spring piece. The bottom of the first and second spring pieces are each equipped with a protrusion.

[0010] Preferably, screws are screwed onto the left and right sides of the side plate at positions corresponding to the end plate, and screw rods are screwed onto the left and right sides of the interior of the end plate, which facilitates assembly.

[0011] Preferably, the aluminum connecting piece is connected to the battery cell and the pressure strip is connected to the end plate by bolts, which facilitates disassembly and assembly.

[0012] Preferably, the upper part of the protrusion is provided with a first inclined portion, the lower part of the first inclined portion is connected to a vertical portion, and the lower part of the vertical portion is connected to a second inclined portion.

[0013] Preferably, the combination of the first inclined section, the vertical section, and the second inclined section forms a trapezoidal shape, and both the first inclined section and the second inclined section are oriented towards the inside of the end plate.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a battery structure that is easy to assemble and has the following beneficial effects:

[0016] This easily assembled battery structure, through the addition of a first spring, a second spring, and a protrusion, allows it to adapt to different tolerance dimensions after the battery cell is inserted. When the tolerance of the battery cell is small, the protrusion at the bottom of the first and second springs will squeeze and limit the battery cell. When the tolerance of the battery cell is large, it will push the protrusion and the first and second springs to move, thereby limiting the battery cell. This can compensate for the battery cell tolerance and better match the screw hole positions of the end plate and side plate, the end plate and sheet metal box, and the end plate and pressure strip. It also reduces assembly difficulties caused by size differences and improves assembly efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a technical solution, a battery structure that is easy to assemble, including a side plate 1, a battery cell 2, an end plate 3, an aluminum connecting piece 4, a pressure strip 5, a screw 6, a bolt 7, a through groove 8, a first spring piece 9, a second spring piece 10, a first inclined section 11, a vertical section 12, a second inclined section 13, and a protrusion 14.

[0023] Please see Figure 1 The side plate 1 has a battery cell 2 inserted inside, and end plates 3 are installed on the left and right sides of the side plate 1. Aluminum connecting pieces 4 are installed on the top of the battery cell 2, and pressure strips 5 are installed in the middle of the top of the end plate 3.

[0024] Please see Figure 2 and Figure 3 The through slots 8 are formed on the left, right, and lower sides of the end plate 3. The upper left and right through slots 8 are each equipped with a first spring piece 9, and the lower through slot 8 is equipped with a second spring piece 10. A protrusion 14 is installed at the bottom of both the first and second spring pieces 9 and 10. Screws 7 are screwed onto the left and right sides of the side plate 1 at positions corresponding to the end plate 3. Screws 6 are screwed onto the left and right sides of the end plate 3. The aluminum connecting piece 4 is connected to the battery cell 2, and the pressure strip 5 is connected to the end plate 3 using bolts. The connection is achieved through the added first spring pieces 9, second spring pieces 10, and protrusions 14. This allows the battery cell 2 to adapt to different tolerance dimensions after insertion. When the tolerance of the battery cell 2 is small, the protrusion 14 at the bottom of the first spring 9 and the second spring 10 will squeeze and limit the battery cell 2. When the tolerance of the battery cell 2 is large, it will push the protrusion 14 and the first spring 9 and the second spring 10 to move, thereby limiting the battery cell 2. This can offset the tolerance of the battery cell 2 and better match the screw hole positions of the end plate 3 and the side plate 1, the end plate 3 and the sheet metal box with the end plate 3 and the pressure strip 5. It also reduces the assembly difficulties caused by size differences and improves the assembly efficiency.

[0025] The upper part of the protrusion 14 is provided with a first inclined part 11, the lower part of the first inclined part 11 is connected to a vertical part 12, and the lower part of the vertical part 12 is connected to a second inclined part 13. The first inclined part 11, the vertical part 12 and the second inclined part 13 are combined to form a trapezoidal shape. Both the first inclined part 11 and the second inclined part 13 are set towards the inside of the end plate 3.

[0026] This solution, through the addition of a first spring 9, a second spring 10, and a protrusion 14, allows for adaptation to different tolerance dimensions after the battery cell 2 is inserted. When the tolerance of the battery cell 2 is small, the protrusion 14 at the bottom of the first spring 9 and the second spring 10 will squeeze and limit the battery cell 2. When the tolerance of the battery cell 2 is large, it will push the movement of the protrusion 14, the first spring 9, and the second spring 10, thereby limiting the battery cell 2. This can offset the tolerance of the battery cell 2 and better align the screw holes of the end plate 3 and the side plate 1, the end plate 3 and the sheet metal box with the end plate 3 and the pressure strip 5, reducing assembly difficulties caused by size differences and improving assembly efficiency.
