[0032] Reference below Figure 1-Figure 9 A battery box 100 according to an embodiment of the first aspect of the present invention is described.

[0033] like Figure 1-Figure 9 As shown, the battery box 100 according to the first embodiment of the utility model comprises a box body 1, a box cover assembly 2 and a plurality of connecting brackets 3. In the description of the utility model, the meaning of "plurality" is two or more. The battery box 100 is suitable for connecting to the frame of a vehicle. But it is not limited to this.

[0034] Specifically, the height direction of the box 1 (for example, Figure 1 The box cover assembly 2 includes a cover body 21 and a cover plate 22 that are detachably connected. The cover body 21 is arranged on the open side of the box body 1. The cover body 21 and the box body 1 together define a receiving cavity 11. The cover plate 22 is arranged on a side of the cover body 21 away from the box body 1. A plurality of connecting brackets 3 are arranged at intervals on the open side of the box body 1. One end of each connecting bracket 3 is connected to the side wall of the box body 1, and the other end of each connecting bracket 3 is connected to the cover body 21.

[0035] For example, in Figure 1-Figure 4 In the example, the box cover assembly 2 is arranged on the open side of the box body 1 in the height direction. When the box cover assembly 2 is away from the open side of the box body 1, the battery 201 is placed in the accommodating cavity 11 or the battery 201 is taken out through the open side of the box body 1, or the battery 201 in the accommodating cavity 11 is inspected through the open side of the box body 1. When the box cover assembly 2 is arranged on the open side of the box body 1, the box cover assembly 2 can protect the battery 201 in the box body 1. Four connecting brackets 3 are arranged at intervals in the circumferential direction of the open side of the box body 1. Each connecting bracket 3 connects the side wall of the box body 1 and the cover body 21, so that the connection between the box body 1 and the cover body 21 is stably connected by the connecting bracket 3.

[0036] The cover body 21 of the box cover assembly 2 is connected to the box body 1 through the connecting bracket 3 on one side in the height direction of the box body 1, and the cover body 21 is connected to the cover plate 22 on the other side in the height direction of the box body 1 to increase the thickness of the box cover assembly 2 in the height direction of the box body 1, thereby increasing the structural strength of the box cover assembly 2, reducing the risk of distortion of the box cover assembly 2, and improving the bearing capacity of the box cover assembly 2, that is, improving the supporting performance of the box cover assembly 2, making it convenient for users to inspect or operate equipment on the cover plate 22, etc., to ensure the personal safety of users.

[0037] At the same time, the cross-sectional area of ​​the cover plate 22 is greater than or equal to the cross-sectional area of ​​the cover body 21, so that the cover plate 22 can be used to protect the cover body 21 to prevent the cover body 21 from aging or other damage caused by the impact of wind and rain, thereby improving the anti-aging ability of the box cover assembly 2 and extending the service life of the box cover assembly 2.

[0038] Optionally, a pattern is formed on a surface of the cover plate 22 on one side away from the cover body 21 to increase the friction of the surface of the cover plate 22 , thereby improving the stability and safety of the user walking on the cover plate 22 .

[0039] According to the battery box 100 of the embodiment of the utility model, by providing a detachably connected cover body 21 and a cover plate 22 on the open side of the box body 1, the structural strength of the box cover assembly 2 is increased, the risk of distortion of the box cover assembly 2 is reduced, and the bearing capacity of the box cover assembly 2 is improved, that is, the supporting performance of the box cover assembly 2 is improved, which is convenient for users to repair or operate equipment on the cover plate 22. At the same time, the cover plate 22 is conducive to protecting the cover body 21, thereby improving the anti-aging ability of the cover body 21 and extending the service life of the box cover assembly 2.

[0040] According to some embodiments of the present invention, referring to Figure 2-Figure 4 , a plurality of first reinforcing ribs 211 are provided on the side of the cover 21 facing the box body 1, and the plurality of first reinforcing ribs 211 are arranged crosswise; and / or a plurality of second reinforcing ribs 12 are provided on the side of the box body 1 adjacent to the accommodating cavity 11, and the plurality of second reinforcing ribs 12 are arranged crosswise. In other words, a plurality of first reinforcing ribs 211 may be provided only on the side of the cover 21 facing the box body 1 (not shown); or, a plurality of second reinforcing ribs 12 may be provided only on the side of the box body 1 adjacent to the accommodating cavity 11 (not shown); or, a plurality of first reinforcing ribs 211 may be provided on the side of the cover 21 facing the box body 1, and a plurality of second reinforcing ribs 12 may be provided on the side of the box body 1 adjacent to the accommodating cavity 11 (refer to Figure 2-Figure 4 ).

[0041] like Figure 2-Figure 4As shown, twenty first reinforcing ribs 211 are provided on the side of the cover 21 facing the box body 1, and the extension directions of ten of the twenty first reinforcing ribs 211 are consistent, and the extension directions of the remaining ten of the twenty first reinforcing ribs 211 are consistent, and the extension directions of the ten first reinforcing ribs 211 and the extension directions of the remaining ten first reinforcing ribs 211 intersect, so that each first reinforcing rib 211 is connected to at least one first reinforcing rib 211, thereby realizing the cross arrangement of the twenty first reinforcing ribs 211. This is conducive to improving the structural strength of the cover 21, improving the stability of the cover 21, and extending the service life of the cover 21.

[0042] For example, ten second reinforcing ribs 12 are arranged on one side wall of the box body 1, and the extension directions of five of the ten second reinforcing ribs 12 are consistent, and the extension directions of the remaining five of the ten second reinforcing ribs 12 are consistent, and the extension directions of the five second reinforcing ribs 12 and the extension directions of the remaining five second reinforcing ribs 12 intersect, so that each second reinforcing rib 12 is connected to at least one second reinforcing rib 12, thereby realizing the cross arrangement of the ten second reinforcing ribs 12. This is conducive to improving the structural strength of the box body 1, improving the stability of the box body 1, and extending the service life of the battery box 100.

[0043] In some optional embodiments, the cover plate 22 is an aluminum alloy plate. The aluminum alloy plate has a low density, but a high strength, good plasticity, easy processing, and excellent electrical conductivity, thermal conductivity, and corrosion resistance. Therefore, using an aluminum alloy plate as the cover plate 22 is conducive to ensuring the structural strength of the cover plate 22 to meet the requirement that the cover plate 22 bears the weight of the user, and at the same time, reduces the processing cost of the cover plate 22, extends the service life of the cover plate 22, thereby improving the stability of the battery box 100 and extending the service life of the battery box 100.

[0044] According to some embodiments of the present invention, referring to Figure 2-Figure 5 Each connecting bracket 3 includes a first bracket segment 31, a second bracket segment 32 and a third bracket segment 33 connected in sequence, the first bracket segment 31 extends along the height direction of the box body 1, and the third bracket segment 33 extends along the length direction of the box cover assembly 2 (for example, Figure 3 ) or widthwise (e.g. Figure 3 The second bracket segment 32 extends in a direction away from the side wall of the box body 1 (in the front-to-back direction), and the second bracket segment 32 extends obliquely.

[0045] Thus, the first bracket segment 31 is connected to the side wall of the box body 1, the third bracket segment 33 is connected to the cover body 21, and the two ends of the second bracket segment 32 are respectively connected to the first bracket segment 31 and the third bracket segment 33. The second bracket segment 32 is used to make the connection position between the third bracket segment 33 and the cover body 21 away from the edge of the open side of the box body 1, so as to facilitate the connection of the cover body 21 to the box body 1, and at the same time, the force at the center of the cover body 21 can be dispersed to the box body 1 through the connecting bracket 3, so as to avoid the center of the cover body 21 being sunken toward the box body 1 after being stressed, thereby improving the stability of the cover body 21 and extending the service life of the cover body 21.

[0046] In addition, refer to Figure 6-Figure 9 The battery box 100 further includes a limiting bracket 4, which is detachably connected to the side wall of the box body 1. The limiting bracket 4 includes a first limiting section 41, a second limiting section 42, and a third limiting section 43 which are connected in sequence. The first limiting section 41 is in contact with the side wall of the box body 1, and the second limiting section 42 extends in a direction perpendicular to the first limiting section 41. The second limiting section 42 is suitable for abutting against the battery 201. Thus, the battery 201 can be limited by the limiting bracket 4, so as to facilitate the installation of batteries 201 of different volumes in the accommodating cavity 11, thereby increasing the applicability of the battery box 100.

[0047] For example, the capacity of the battery 201 is 180Ah, 220Ah, 240Ah or 330Ah, and the capacity of the battery 201 is positively correlated with the volume of the battery 201. However, the invention is not limited thereto. The battery 201 may be a lithium battery. However, the invention is not limited thereto.

[0048] The first limiting section 41 of the limiting bracket 4 is suitable for connecting with the side wall of the box body 1 to achieve the positioning of the limiting bracket 4. The second limiting section 42 is perpendicular to the first limiting section 41, so that the second limiting section 42 can completely stop on the surface of the battery 201, thereby limiting the battery 201.

[0049] The third limiting section 43 and the first limiting section 41 are located in the thickness direction of the second limiting section 42 (for example, Figure 8 The third limiting section 43 and the second limiting section 42 are on the same side of the left and right directions in the box body 1, and the angle between the third limiting section 43 and the second limiting section 42 is an obtuse angle. The third limiting section 43 extends along the side away from the second limiting section 42 and the battery 201, so that the third limiting section 43 is conducive to guiding the battery 201, so as to facilitate the installation of the battery 201 in the installation area defined by the limiting bracket 4 and the box body 1, and at the same time prevent the limiting bracket 4 from causing damage to the surface of the battery 201.

[0050] Optionally, the limiting bracket 4 also includes a fourth limiting section 44, one end of the fourth limiting section 44 is connected to the first limiting section 41, and the other end of the first limiting section 41 extends in a direction perpendicular to the first limiting section 41. Thus, when the limiting bracket 4 is arranged on the side wall of the box body 1, the first limiting section 41 and the second limiting section 42 can both fit with the side wall of the box body 1, thereby increasing the fitting area between the limiting bracket 4 and the box body 1 and increasing the setting stability of the limiting bracket 4.

[0051] Furthermore, if Figure 8 As shown, the angle between the third limiting section 43 and the second limiting section 42 is α, wherein α satisfies: 100°≤α≤110°. When α<100°, the angle between the third limiting section 43 and the second limiting section 42 is small, which is not conducive to the third limiting section 43 guiding the battery 201, and the connection position between the third limiting section 43 and the second limiting section 42 is easy to cause damage to the surface of the battery 201; when α>110°, the angle between the third limiting section 43 and the second limiting section 42 is large, which is not conducive to the third limiting section 43 guiding the battery 201, and the end of the third limiting section 43 away from the second limiting section 42 is easy to cause damage to the surface of the battery 201. Therefore, by setting the angle between the third limit section 43 and the second limit section 42 to 100°≤α≤110°, the third limit section 43 guides the installation of the battery 201 in the installation area defined by the limit bracket 4 and the box body 1, while preventing the limit bracket 4 from causing damage to the surface of the battery 201.

[0052] According to some embodiments of the present invention, Figure 8 As shown, the thickness of the limit bracket 4 is D, where D satisfies: 2mm≤D≤5mm. When D<2mm, the thickness of the limit bracket 4 is small, and the structural strength of the limit bracket 4 is small, so the limit bracket 4 is easily damaged, which reduces the service life of the limit bracket 4 and reduces the installation stability of the battery 201 in the accommodating cavity 11; when D>5mm, the thickness of the limit bracket 4 is large, and on the basis of meeting the use requirements of the limit bracket 4, the volume of the limit bracket 4 is increased, thereby reducing the applicability of the limit bracket 4, that is, in the limited space of the accommodating cavity 11, the limit bracket 4 is not suitable for the situation where the space between the inner wall of the box body 1 and the battery 201 is small, and the weight of the limit bracket 4 increases, which increases the weight of the battery box 100. Therefore, by setting the thickness of the limit bracket 4 to 2mm≤D≤5mm, the limit bracket 4 can stably stop the battery 201, while increasing the applicability of the limit bracket 4 and extending the service life of the limit bracket 4.

[0053] In some optional embodiments, referring to Figure 6The battery box 100 further includes at least one pressing plate 5 and a plurality of tie rods 6. The pressing plate 5 is disposed in the accommodating cavity 11, and the pressing plate 5 is adapted to contact the outer peripheral surface of the battery 201. The plurality of tie rods 6 are disposed in the accommodating cavity 11, one end of each tie rod 6 is connected to the pressing plate 5, and the other end of each tie rod 6 is connected to the bottom wall of the box body 1.

[0054] A pressing plate 5 and a pull rod 6 are provided in the battery box 100, and at least one pull rod 6 is connected to each pressing plate 5. Thus, the pull rod 6 is connected to the pressing plate 5 and the bottom wall of the box body 1, which is conducive to controlling the relative position of the pressing plate 5 in the box body 1 to remain unchanged. The pull rod 6 and the pressing plate 5 cooperate to limit the battery 201 and prevent the battery 201 from moving in the accommodating cavity 11, thereby increasing the installation and use stability of the battery 201, and at the same time increasing the use stability of the battery box 100.

[0055] Reference Figure 6 According to the second aspect of the utility model, the battery 200 includes a battery box 100, a battery 201 and a buffer. The battery box 100 is the battery box 100 according to the first aspect of the utility model. The battery 201 is arranged in the accommodating cavity 11 of the battery box 100. The buffer is arranged between the outer peripheral surface of the battery 201 and the inner wall of the battery box 100. Therefore, the use of the buffer to protect the battery 201 is conducive to increasing the friction of the surface of the battery 201, effectively preventing the battery 201 from sliding in the accommodating cavity 11, and avoiding direct contact between the battery 201 and the inner wall of the battery box 100 to cause damage to the surface of the battery 201.

[0056] The battery 200 according to the embodiment of the utility model, by adopting the above-mentioned battery box 100, is conducive to increasing the installation and use stability of the battery 200, thereby improving the market competitiveness of the battery 200.
