[0033] The battery pack fixing structure 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0034] Reference Figure 1 and Figure 2 As shown, the battery pack fixing structure 100 according to an embodiment of the present utility model may include: a base plate 10 and a fixing plate 20.

[0035] Specifically, the fixing plate 20 is connected to the outer peripheral wall of the base plate 10, and the fixing plate 20 extends along the circumferential direction of the base plate 10, so that the base plate 10 can support the battery pack. The fixing plate 20 can limit the battery pack, so that the battery pack can be fixed to the equipment (such as a vehicle) through the battery pack fixing structure 100 to meet the required fixing requirements.

[0036] In related technologies, because the size of the battery pack fixing structure is fixed, the battery pack fixing structure can only be used to fix one type and size of battery pack, resulting in poor applicability.

[0037] Therefore, in this utility model, such as Figure 1 and Figure 2 As shown, the battery pack fixing structure 100 also includes a first adjustment mechanism 30. The first adjustment mechanism 30 includes a movable plate 31 and a first adjustment member 32. The movable plate 31 can move between the fixing plate 20 and the battery pack. The first adjustment member 32 can drive the movable plate 31 to move towards the battery pack, making the size of the battery pack fixing structure 100 adjustable. For example, the horizontal size of the battery pack fixing structure 100 can be adjusted. The battery pack can be limited by the movable plate 31 and the fixing plate 20, enabling the fixing of battery packs of different sizes, ensuring the stability and safety of the battery pack in the equipment, thereby realizing the universality of the battery pack fixing structure 100 for different models of battery packs. At the same time, the structure of the first adjustment mechanism 30 is simple, easy to process and manufacture, and helps to reduce production costs.

[0038] Therefore, the following problems can be solved by adjusting the size of the battery pack fixing structure 100:

[0039] 1. Simplified installation and maintenance: Since the size of the battery pack fixing structure 100 is adjustable, it is easy to standardize the battery pack fixing structure 100, thereby simplifying the installation and disassembly process of the battery pack, facilitating quick replacement or repair, and reducing maintenance costs and time.

[0040] 2. Improved interchangeability: By using the same battery pack fixing structure 100 on the same type of equipment (such as vehicles), different types and sizes of battery packs can be interchanged on the same type of equipment, increasing flexibility and selectivity.

[0041] 3. Reduced costs: A unified battery pack mounting structure 100 helps reduce design and manufacturing costs, eliminating the need to design a separate battery pack mounting structure 100 for each type of battery pack, and enabling the mass production of standardized parts, which further reduces production costs.

[0042] 4. Optimize space utilization: The unified battery pack fixing structure 100 allows for better planning of the battery pack layout inside the equipment, optimizing space utilization and improving energy efficiency and equipment performance.

[0043] In the battery pack fixing structure 100 of this embodiment, a base plate 10 supports the battery pack. A fixing plate 20 is connected to the outer peripheral wall of the base plate 10 and extends along the circumferential direction of the base plate 10. A movable plate 31 can move between the fixing plate 20 and the battery pack. A first adjusting member 32 drives the movable plate 31 to move towards the battery pack, making the size of the battery pack fixing structure 100 adjustable. This allows for fixing battery packs of different sizes, increasing flexibility and selectivity, ensuring the stability and safety of the battery pack in the equipment, and thus achieving universality of the battery pack fixing structure 100 for different models of battery packs. This facilitates the planning of the battery pack layout inside the equipment and optimizes space utilization. Furthermore, there is no need to design a separate battery pack fixing structure 100 for each type of battery pack, and the structure of the first adjusting mechanism 30 is simple, easy to manufacture, and helps reduce production costs.

[0044] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, there are multiple first adjustment mechanisms 30, which are spaced apart along the circumferential direction of the base plate 10. The multiple first adjustment mechanisms 30 can apply pressure to the battery pack from multiple different directions. For example, the battery pack can be limited and fixed in multiple places in the horizontal direction, thereby ensuring reliable battery pack positioning, reducing movement of the battery pack, and improving assembly efficiency.

[0045] In embodiments of this utility model, the number of first adjusting mechanisms 30 can be flexibly set according to actual conditions. For example, the number of first adjusting mechanisms 30 can be as follows: Figure 1 The number shown is four, but it can also be two, three, five, six or more, all of which are within the protection scope of this utility model.

[0046] In some embodiments, such as Figure 1 and Figure 2As shown, the fixing plate 20 includes multiple fixing sub-plates 21, which are spaced apart along the circumferential direction of the base plate 10. At least two pairs of oppositely arranged fixing sub-plates 21 are included among the multiple fixing sub-plates 21, and the two pairs of oppositely arranged fixing sub-plates 21 are arranged perpendicular to each other. Multiple first adjustment mechanisms 30 can be respectively set on the two pairs of fixing sub-plates 21 to facilitate the placement of the first adjustment structure. The first adjustment members 32 of the two opposite first adjustment mechanisms 30 can adjust the distance between the two moving plates 31 located on the same side to ensure reliable fixing of the battery pack and meet the required fixing requirements.

[0047] In embodiments of this utility model, the number of fixing sub-plates 21 can be flexibly set according to actual conditions. For example, the fixing sub-plates 21 can be as follows: Figure 1 The number shown is four, but it can also be two, three, five, six or more, all of which are within the protection scope of this utility model.

[0048] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the first adjusting member 32 passes through the fixed plate 20 and is threadedly connected to the fixed plate 20. The end of the first adjusting member 32 near the battery pack in the length direction abuts or rotates with the moving plate 31. By rotating the first adjusting member 32, the moving plate 31 can be pushed, thereby driving the moving plate 31 to move, making the adjustment reliable, easy to operate and easy to control.

[0049] In some embodiments, such as Figure 1 and Figure 2 As shown, the first adjusting member 32 can be a bolt, which makes the structure of the first adjusting mechanism 30 simple, easy to process and manufacture, and helps to reduce production costs.

[0050] In some embodiments of this utility model, such as Figure 3 As shown, the base plate 10 has a movable hole 11. The movable plate 31 includes a plate body 311 and a slider 312. The plate body 311 is located between the fixed plate 20 and the battery pack. The slider 312 is disposed on the outer peripheral wall of the plate body 311. The slider 312 passes through the movable hole 11 and can slide along the length direction of the movable hole 11. When the first adjusting member 32 drives the movable plate 31 to move towards the battery pack, the slider 312 can be limited by the movable hole 11, which facilitates the movement of the movable plate 31 between the fixed plate 20 and the battery pack, ensuring that the movement of the movable plate 31 towards the battery pack is reliable and makes the movement of the movable plate 31 more stable, ensuring reliable fixation of the battery pack. At the same time, the movable plate 31 has a simple structure, is easy to process and manufacture, and helps to reduce production costs.

[0051] In some embodiments, such as Figure 3As shown, there are multiple sliders 312, which are spaced apart along the length of the plate body 311 to improve the structural strength of the moving plate 31. There are multiple moving holes 11 that correspond one-to-one with the sliders 312. By cooperating with the multiple sliders 312 and the multiple moving holes 11, the movement of the moving plate 31 can be ensured to be reliable, and problems such as deformation of the sliders 312 can be avoided, thus ensuring reliable fixation of the battery pack.

[0052] In embodiments of this utility model, the number of sliders 312 can be flexibly set according to actual conditions. For example, the number of sliders 312 can be as follows: Figure 3 The number shown is two, but it can also be three, four, five, six or more, all of which are within the protection scope of this utility model.

[0053] According to some embodiments of this utility model, such as Figure 3 As shown, the movable plate 31 also includes a locking block 313, which is connected to the end of the slider 312 away from the plate body 311 (e.g., Figure 1 The lower end shown in the diagram is connected, and the card block 313 can be connected to the side of the base plate 10 away from the battery pack (e.g., the lower end shown in the diagram). Figure 1 The lower side shown in the figure abuts against the moving plate 313, so that the locking block 313 can limit the moving plate 31, for example, limit the moving plate 31 in the vertical direction, prevent the moving plate 31 from coming out of the moving hole 11 during the movement, which helps to improve the strength and stability of the battery pack fixing structure 100, and can further enhance the fixing effect of the moving plate 31 on the battery pack, ensuring that the battery pack is fixed reliably.

[0054] In some embodiments, such as Figure 2 As shown, the side of the base plate 10 furthest from the battery pack (e.g.) Figure 1 A pad 40 is connected to the lower side shown in the diagram. The pad 40 is located on one side of the locking block 313, along the thickness direction of the base plate 10 (e.g., the lower side). Figure 1 (As shown in the up-down direction), the height of the pad 40 is greater than the height of the locking block 313. The pad 40 can protect the base plate 10, and when the base plate 10 is assembled on the equipment, the pad 40 can prevent the locking block 313 from interfering with other structures, so that there is enough gap between the base plate 10 and the fixed surface for the locking block 313 to slide normally, ensuring that the moving plate 31 moves reliably.

[0055] In some embodiments, such as Figure 1 and Figure 2 As shown, the base plate 10 is rectangular, and a pad 40 is provided at each of the four corners of the rectangle. The pads 40 are all located on one side of the locking block 313 to avoid interference between the pads 40 and the locking block 313, ensuring that the moving plate 31 moves reliably. The four pads can also ensure reliable support for the base plate 10, preventing the base plate 10 from tilting, thereby ensuring that the battery pack is placed reliably on the base plate 10.

[0056] In some embodiments of this utility model, such as Figures 1-3 As shown, the battery pack fixing structure 100 also includes a second adjustment mechanism 50, which is disposed on the movable plate 31. The second adjustment mechanism 50 can prevent the battery pack from moving away from the base plate 10 (e.g., Figure 1 The movement of the upper side shown in the figure can ensure that the battery pack is positioned on the base plate 10, thereby ensuring that the battery pack is reliably fixed on the battery pack fixing structure 100 and avoiding the need to meet the required fixing requirements.

[0057] According to some embodiments of this utility model, such as Figures 1-3 As shown, the second adjustment mechanism 50 includes an adjustment component 51 and a second adjustment member 52. The adjustment component 51 is movably mounted on the movable plate 31, and the direction of movement of the adjustment component 51 is perpendicular to the direction of movement of the movable plate 31. The second adjustment member 52 passes through the movable plate 31 and the adjustment component 51, and the second adjustment member 52 can drive the adjustment component 51 towards a direction closer to or further away from the battery pack (e.g., ...). Figure 1 The adjustment component 51, as shown in the vertical direction, moves so that the adjustment component 51, through the adjustment of the second adjustment member 52, can prevent battery packs of different sizes from moving away from the base plate 10. This makes the dimensions of the battery pack fixing structure 100 adjustable; for example, it allows for vertical dimension adjustment, enabling the fixing of battery packs of different sizes and ensuring the stability and safety of the battery packs in the equipment. This achieves universality of the battery pack fixing structure 100 for different battery pack models. Simultaneously, the second adjustment mechanism 50 has a simple structure, is easy to manufacture, and helps reduce production costs.

[0058] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the second adjustment mechanism 50 further includes an elastic element 53, which is sleeved on the second adjustment member 52 and located between the adjustment assembly 51 and the moving plate 31. The elastic element 53 can drive the adjustment assembly 51 in a direction away from the battery pack (e.g., Figure 1 The upper part (as shown) can be moved to adjust the adjustment component 51 according to different movement requirements, making adjustment convenient and improving assembly and disassembly efficiency. For example, the elastic element 53 can be a spring, etc.

[0059] In some embodiments, such as Figure 1 and Figure 2 As shown, the adjusting assembly 51 is provided with a connecting hole, and the second adjusting component 52 includes a bolt rod and a bolt head. One end of the bolt rod passes through the connecting hole and is threadedly connected to the moving plate 31. The bolt head is located at the end of the bolt rod away from the base plate 10 along its length (e.g., ...). Figure 1The upper end shown), the bolt head and the end of the adjusting assembly 51 away from the base plate 10 (e.g., the upper end), Figure 1 (as shown above) abuts against each other.

[0060] Therefore, when the second adjusting member 52 is turned, the adjusting assembly 51 can be controlled to move toward or away from the base plate 10, for example, controlling the raising or lowering of the adjusting assembly 51. When the bolt head moves toward the base plate 10, the bolt head drives the adjusting assembly 51 to move toward the base plate 10 until the adjusting assembly 51 is aligned with the side of the battery pack that is away from the base plate 10 (e.g., the side opposite to the base plate 10). Figure 1 The upper side shown in the diagram is closely attached to the battery pack, thereby achieving a limiting and fixing effect.

[0061] Meanwhile, the elastic element 53 is always in a compressed state between the adjusting component 51 and the moving plate 31. Therefore, the elastic element 53 can always provide the adjusting component 51 with a thrust to move away from the battery pack, so that the adjusting component 51 can follow the second adjusting component 52 under the thrust of the elastic element 53. That is, when the bolt head moves away from the base plate 10, the elastic element 53 will drive the adjusting component 51 to move away from the base plate 10, meet the required adjustment needs, and facilitate disassembly.

[0062] According to some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the movable plate 31 is provided with a clearance hole 314, and the adjustment assembly 51 includes an adjustment plate 511, a guide rod 512 and a pressing plate 513. The adjustment plate 511 is located on the side of the movable plate 31 away from the base plate 10 (e.g., Figure 1 (as shown on the upper side), one end of the guide rod 512 in the length direction (e.g., the upper side), Figure 3 The upper end shown is connected to the adjusting plate 511, and the other end of the guide rod 512 in the length direction faces the direction close to the base plate 10 (e.g., Figure 3 The lower part (as shown in the diagram) extends and enters the clearance hole 314, the clamping plate 513 passes through the clearance hole 314, and the clamping plate 513 and the guide rod 512 are located at the end away from the adjusting plate 511 (e.g., the lower part). Figure 3 The lower end shown is connected, and the clamping plate 513 moves along the length direction of the clearance hole 314. The clearance hole 314 can allow the guide rod 512 and the clamping plate 513 to pass through, that is, the clearance hole 314 provides space for the movement of the adjustment component 51, which can ensure a compact structure, reduce weight, facilitate the miniaturization of the battery pack fixing structure 100, and the adjustment component 51 has a simple structure, which is easy to process and manufacture, and helps to reduce production costs.

[0063] The second adjusting member 52 passes through the adjusting plate 511. The second adjusting member 52 can drive the adjusting plate 511 to move towards the direction closer to the battery pack. The adjusting plate 511 can drive the guide rod 512 and the pressing plate 513 to move together towards the direction closer to the battery pack. The pressing plate 513 can abut against the side of the battery pack away from the bottom plate 10 to achieve the requirement of fixing the battery pack. The guide rod 512 can play a guiding role to ensure that the pressing plate 513 moves reliably along the length direction of the clearance hole 314 and avoids problems such as displacement, thereby ensuring the stability and guidance of the adjusting assembly 51 during the movement.

[0064] In some embodiments, such as Figure 3 As shown, there are multiple guide rods 512, which are spaced apart along the length of the adjusting plate 511. Each guide rod 512 is equipped with a clamping plate 513. The multiple guide rods 512 can ensure the reliable movement of the adjusting component 51 and prevent deviation. The multiple clamping plates 513 can ensure the limiting of multiple different positions on the side of the battery pack away from the base plate 10, ensuring the reliable fixing of the battery pack.

[0065] In embodiments of this utility model, the number of guide rods 512 can be flexibly set according to actual conditions. For example, the guide rods 512 can be as follows: Figure 3 The number shown is two, but it can also be three, four, five, six or more, all of which are within the protection scope of this utility model.

[0066] The vehicle according to an embodiment of the present invention includes a battery pack fixing structure 100 according to an embodiment of the present invention. Since the battery pack fixing structure 100 according to an embodiment of the present invention has the aforementioned beneficial technical effects, the vehicle according to an embodiment of the present invention uses a base plate 10 to support the battery pack. A fixing plate 20 is connected to the outer peripheral wall of the base plate 10 and extends along the circumferential direction of the base plate 10. A movable plate 31 can move between the fixing plate 20 and the battery pack. A first adjusting member 32 drives the movable plate 31 to move towards the battery pack, making the size of the battery pack fixing structure 100 adjustable. This allows for fixing battery packs of different sizes, increasing flexibility and selectivity, ensuring the stability and safety of the battery pack in the equipment, and thus achieving universality of the battery pack fixing structure 100 for different models of battery packs. This facilitates planning the layout of the battery pack inside the equipment and optimizes space utilization. Furthermore, there is no need to design a separate battery pack fixing structure 100 for each type of battery pack, and the structure of the first adjusting mechanism 30 is simple, easy to manufacture, and helps reduce production costs.

[0067] In some embodiments, since battery packs vary in type and size, the battery pack fixing structure 100 of this invention can fix battery packs of different types and sizes when they are installed in a vehicle, meeting the required fixing needs. Furthermore, a consistent battery pack fixing structure 100 can ensure the stability and safety of the battery pack in the vehicle. For example, the vehicle can be an electric vehicle.
