Description

Technical Field

[0001] This disclosure relates to a battery holder and a battery pack including the battery holder. Background Technology

[0002] Currently, in the battery pack manufacturing process, multiple battery cells need to be placed in a battery bracket, and then the battery bracket containing the multiple battery cells is placed into a shell with an inner wall covered with cushioning material, thus completing the battery pack assembly. The cushioning material is used to reduce the impact of external vibrations on the battery bracket and battery cells. Utility Model Content

[0003] The problem that the utility model aims to solve

[0004] However, in the aforementioned battery pack, the battery bracket and the cushioning material are in contact with each other over a single surface, which leads to the following problems:

[0005] (i) The battery bracket and the inner wall of the casing are in full-surface contact. Due to the large contact area, the friction between the battery bracket and the buffer material is large, making it difficult for the battery to be placed into the casing.

[0006] (ii) If the battery holder and the casing are to be matched and contacted in a way that makes full-surface contact, the requirements for the precision of component processing are high, which increases the cost.

[0007] (III) Due to manufacturing errors, if the battery holder is too large, it will be difficult to fit into the casing. If the battery holder is too small, the compression of the cushioning material will be insufficient, and it will not fit tightly against the battery holder. As a result, the battery holder will wobble inside the casing, reducing its stability. Moreover, because the cushioning material is not fully compressed, its cushioning performance will decrease, and it will not be able to effectively disperse or absorb impact energy. The battery protected in the battery holder will be easily damaged by impact during transportation or use, and there may even be safety hazards.

[0008] means for solving problems

[0009] This disclosure was made in view of the above circumstances, and its object is to provide a battery holder and a battery pack including the battery holder, wherein the battery holder can be easily inserted into a housing with an inner wall covered with cushioning material, and is highly stable and easy to manufacture.

[0010] The battery holder of the first embodiment of the present invention has a first clamping mechanism and a second clamping mechanism. The first clamping mechanism and the second clamping mechanism form a space for clamping multiple battery cells. The battery holder is capable of clamping multiple battery cells through the first clamping mechanism and the second clamping mechanism. Multiple ribs are formed on the side surfaces of the first clamping mechanism and the second clamping mechanism, protruding from the side surfaces of the first clamping mechanism and extending in the vertical direction.

[0011] The second embodiment of the battery holder of this utility model is that, in the battery holder of the first embodiment, the height of the rib protruding from the side surface of the first clamping mechanism and the side surface of the second clamping mechanism gradually decreases from the upper direction in the vertical direction to the lower direction, and the rib is formed into a wedge shape.

[0012] The third-party battery holder of this utility model is such that, in the battery holder of the first and second methods, when the battery cell is clamped by the first clamping mechanism and the second clamping mechanism, the ribs formed on the side surface of the first clamping mechanism and the corresponding ribs formed on the side surface of the second clamping mechanism are located on the same straight line.

[0013] The fourth embodiment of the battery holder of this utility model is as follows: in the battery holders of the first and second embodiments, the battery holder has an upper support serving as the first clamping mechanism and a lower support serving as the second clamping mechanism, and the upper support and the lower support have a cuboid support body portion.

[0014] The fifth embodiment of the battery holder of this utility model is that, in the battery holder of the fourth embodiment, the ribs are formed on each side surface of the main body of the holder.

[0015] The battery pack of the first embodiment of this utility model includes: a housing, the housing being composed of a lower housing and an upper cover, the upper surface of the lower housing being open and the inner wall being covered with a cushioning material; and a battery support as described in any one of embodiments one to five, wherein the plurality of ribs are embedded in the cushioning material.

[0016] The second embodiment of the battery pack of this utility model is that, in the first embodiment of the battery pack, the cushioning material is cushioning cotton.

[0017] Effects of the utility model

[0018] According to this invention, the battery pack, because the ribs are embedded in the cushioning material, prevents the battery holder from sliding and wobbling within the battery pack casing, thus improving the stability of the battery holder. Furthermore, since the battery holder and the lower casing contact each other through the ribs and the cushioning material, the contact area is reduced, making it easier to insert the battery holder into the battery pack casing. In addition, by forming the ribs in a wedge shape, they can be easily embedded into the cushioning material from above, further facilitating the insertion of the battery holder into the battery pack casing. Moreover, the ribs can compensate for dimensional errors between the battery holder and the casing, reducing the manufacturing difficulty of the battery holder and casing.

[0028] Figure 1 This is a side view of a battery holder according to an embodiment of the present invention. Figure 2 This is a top view of a battery holder according to an embodiment of this utility model. (As shown) Figure 1 As shown, the battery holder 1 of this embodiment includes an upper holder 11 and a lower holder 12. The upper holder 11 and the lower holder 12 can clamp multiple battery cells between them to fix the multiple battery cells. In this embodiment, the upper holder 11 and the lower holder 12 have roughly the same shape and structure. Hereinafter, the upper holder 11 will be used as an example for explanation.

[0029] like Figure 2 As shown, in a top view, the upper bracket 11 has a rectangular bracket body and four protrusions. The four protrusions are formed on the two short sides near the two ends, protruding horizontally along the direction of the long sides. The rectangular bracket body and the four protrusions together constitute the outer contour of the upper bracket 11. It should be noted that the shape of the battery bracket and the number of protrusions are not fixed and can be changed according to the shape of the battery. In addition, the battery bracket may also not have protrusions.

[0030] like Figure 1 and Figure 2As shown, in this embodiment, a plurality of ribs 111 protruding outward from the side of the upper bracket 11 are provided on the side of the upper bracket 11, and a plurality of ribs 121 protruding outward from the side of the lower bracket 12 are provided on the side of the lower bracket 12. In this embodiment, the plurality of ribs 111 and the plurality of ribs 121 are arranged along the height direction of the upper bracket 11 and the lower bracket 12, i.e., the vertical direction, and the ribs 111 and ribs 121 are located on the same straight line. Six ribs are provided on each of the two long sides of the bracket body of the upper bracket 11 and the lower bracket 12, and one rib is provided on each of the four protrusions of the upper bracket 11 and the lower bracket 12. That is, there are a total of 16 ribs on the upper bracket 11. Similarly, 16 ribs are provided on the lower bracket 12 at positions corresponding to those on the upper bracket 11. In addition, the number of ribs is arbitrary. Preferably, each side of the battery bracket 1 has at least one rib that contacts the cushioning material of the lower housing 3, and more preferably, each side of the battery bracket 1 has two or more ribs that contact the cushioning material of the lower housing 3. Furthermore, it is preferable that the number of ribs in the upper support 11 is the same as the number of ribs in the lower support 12, but they may also be different. In addition, it is preferable that the ribs in the upper support 11 and the lower support 12 are located on the same straight line, but they may also be staggered and not located on the same straight line.

[0031] Next, use Figure 1 The enlarged view in the figure illustrates the shape of the ribs. In this embodiment, each rib has a wedge shape, that is, the height of each rib protruding from the side of the battery holder 1 decreases as it faces vertically downward.

[0032] Next, use Figures 3 to 5 This will explain the structure and assembly process of the battery pack using the aforementioned battery holder. Figure 3 This is a top view of the lower casing of the battery pack according to an embodiment of the present invention. Figure 4 This is a 3D view showing the battery holder being assembled into the lower housing. Figure 5 This is a top view of the battery pack with the top cover removed, according to this utility model.

[0033] The battery pack casing consists of a lower casing 3 and an upper cover (not shown), as follows: Figures 3 to 5 As shown, the lower housing 3 is box-shaped with an opening on the upper surface. A cushioning material 31 is attached to the inner wall of the lower housing 3. The material and thickness of the cushioning material 31 are not particularly limited, as long as it achieves a cushioning effect; for example, it can be made of cotton with a thickness of 1.5 mm. Figure 4 As shown, during battery pack assembly, the battery holder 1, which holds multiple battery cells, is horizontally inserted into the lower housing 3 through the opening. Figure 5As shown in the enlarged view, the battery holder 1 does not contact the lower housing 3 with its entire side surface, but rather primarily through ribs. Therefore, when the battery holder 1 is horizontally inserted into the lower housing 3 through the opening, the friction between the entire side surface of the battery holder 1 and the cushioning material in the lower housing 3 is reduced. Furthermore, because the ribs are wedge-shaped, the battery holder 1 can be easily inserted into the cushioning material of the lower housing 3 constituting the battery pack from above. Moreover, after the battery holder 1 is inserted into the cushioning material of the lower housing 3 constituting the battery pack from above, the ribs embed into the cushioning material, ensuring the battery holder 1 remains stable and preventing slippage and wobbling.

[0034] According to this utility model, the following beneficial effects can be obtained: Since the ribs are embedded in the cushioning material, the battery holder can be prevented from sliding and shaking in the battery pack casing, thus improving the stability of the battery holder; Since the battery holder and the lower casing are in contact through the ribs and the cushioning material, the contact area is reduced, making it easier to insert the battery holder into the battery pack casing; By forming the ribs into a wedge shape, the ribs can be easily embedded into the cushioning material from above, making it easier to insert the battery holder into the battery pack casing; The ribs can compensate for the dimensional errors between the battery holder and the casing, reducing the manufacturing difficulty of the battery holder and the casing.

[0035] The battery holder and battery pack including the battery holder of this utility model have been described above. However, this utility model is not limited to the above-described embodiments and various modifications can be made without departing from the spirit of this utility model.

[0036] For example, in the above embodiments, the battery holder consists of an upper bracket and a lower bracket. However, the structure of the battery holder is not limited to this; it can be used as long as it can fix multiple individual units. In addition, in the above embodiments, the upper bracket and the lower bracket have a rectangular bracket body and four protrusions, which are formed on the two short sides near the two ends. However, the shape of the battery holder and the number of protrusions are not fixed and can be changed according to the shape of the battery. Alternatively, the battery holder may not have protrusions.

[0037] It will be apparent to those skilled in the art that various omissions, modifications, and variations can be made to this utility model without departing from its spirit or scope. Therefore, it should be understood that this utility model includes changes and variations within the scope of the appended claims and their equivalents. In particular, it should be understood that any combination of any part or all of any two or more of the above-described embodiments and their variations is within the scope of this utility model.
