Embodiments of the present invention are described in detail below, the embodiments described with reference to the drawings are exemplary, and a battery 100 according to an embodiment of the present invention, including a case 10 and a cell module 20, is described below with reference to fig. 1 to 5.

Specifically, as shown in fig. 1 to 5, the battery 100 includes a casing 10 and a cell module 20, and the cell module 20 is disposed in the casing 10. The top of the housing 10 is provided with at least one mounting portion 30, the mounting portion 30 defines an accommodating chamber 31 therein, an opening 311 and a drain hole 312 are formed on the wall of the accommodating chamber 31, the drain hole 312 is located below the opening 311, and here, "below" does not mean directly below, and may mean an oblique downward direction.

The mounting portion 30 may be used to mount components of the battery 100. Through setting up opening 311, inside can stretch into holding chamber 31 through opening 311 of spare part to improve the reliability of the installation of spare part, simple to operate. Meanwhile, the occupied space can be reduced, which is advantageous for the miniaturized design of the battery 100. However, if the battery 100 is in a humid environment or liquid drops into the battery 100, the liquid flows into the accommodating chamber 31 through the opening 311. And through setting up outage 312, can discharge from outage 312 the liquid that holds in holding chamber 31 inside to avoid liquid to get into inside casing 10 or the holding is holding inside chamber 31 through holding chamber 31, so can do benefit to and hold the inside environment drying of chamber 31 and casing 10, do benefit to the life who prolongs battery 100, the cost is reduced.

According to the battery 100 of the embodiment of the utility model, the installation part 30 is arranged on the top of the shell 10, so that other components of the battery 100 can be conveniently installed, meanwhile, the opening 311 is arranged on the installation part 30, so that the components installed on the installation part 30 can be conveniently accommodated in the accommodating cavity 31, and the miniaturization design of the battery 100 is facilitated. Meanwhile, the drain hole 312 is located below the opening 311, and liquid or accumulated water entering the accommodating cavity 31 from the opening 311 can flow out through the drain hole 312, so as to ensure that the accommodating cavity 31 and the environment inside the housing 10 are dry, which is beneficial to prolonging the service life of the battery 100.

In some embodiments, referring to fig. 1 and 2, the drain hole 312 may be formed at a lower portion of the mounting portion 30, and the drain hole 312 may penetrate through a bottom surface of the cavity wall of the mounting portion 30. For example, the drain hole 312 is formed on a wall of the housing chamber 31 near the middle of the housing 10, and the drain hole 312 is provided on the wall of the chamber near the top surface of the housing 10.

Therefore, by arranging the drainage hole 312 at the lower part of the mounting part 30 and making the drainage hole 312 penetrate the part of the wall of the mounting part 30 close to the top surface of the housing 10, the position where the drainage hole 312 is arranged is as far as possible at the bottom of the accommodating cavity 31, so that the water flow collected in the accommodating cavity 31 flows out from the drainage hole 312 to the maximum extent, and the water flow in the accommodating cavity 31 is prevented from permeating into the housing 10 and affecting the normal use of the battery 100.

Further, as shown in fig. 2, the lower portion of the mounting portion 30 extends obliquely from top to bottom in a direction away from the center of the accommodating chamber 31. As shown in fig. 2, the top surface of the casing 10 contacts the lower portion of the mounting portion 30, and the lower portion of the mounting portion 30 and the top surface are transited by an arc-shaped surface, which may extend along the central axis direction of the battery cell. Specifically, the lower portion of the mounting portion 30 may be bent from the top of the housing 10 to the lower portion of the housing 10 toward the center of the housing 10.

Thus, the lower portion of the mounting portion 30 extends obliquely from top to bottom in a direction away from the center of the accommodating chamber 31, so that water droplets of the mounting portion 30 can flow out along the obliquely extending slope to prevent liquid from entering the inside of the housing 10. Meanwhile, the liquid flowing out of the liquid discharge hole 312 may rapidly flow to the edge of the case 10 through the inclined surface of the lower portion of the mounting portion 30, so that the liquid may be dropped to the ground.

For example, as shown in fig. 2, the outer surface of the housing 10 may form an arc-shaped arc surface 32, for example, the lower portion of the mounting portion 30 may be the arc surface 32, the liquid discharge hole 312 may be formed in the arc surface 32, and the arc surface 32 may extend in the left-right direction of the housing 10. Thus, it is possible to facilitate forming the inclination of the drain hole 312 to facilitate the processing between the top surface of the housing 10 and the mounting portion 30.

In some embodiments, referring to fig. 2 and 4, drain hole 312 may be located directly below opening 311. Therefore, by arranging the drain hole 312 directly below the opening 311, the water flowing into the accommodating chamber 31 through the opening 311 can flow into the drain hole 312 as soon as possible, and the time for the water to collect inside the accommodating chamber 31 is reduced, so that the water can flow out from the drain hole 312 more quickly.

In some embodiments, as shown in FIGS. 1 and 2, drain holes 312 have a height D₁，D₁Satisfies the following conditions: d is not less than 3mm₁Less than or equal to 7 mm. For example, the height of the drain holes 312 may satisfy D₁5mm, when the height D of the drain hole 312 is larger₁When satisfying above-mentioned scope, can guarantee that outage 312 has the optimal flowing back effect to make rivers can be faster flow out from outage 312. Meanwhile, the device does not occupy too much space and is convenient to process. Here, the "height of the drain hole 312" may be a distance between the upper end and the lower end of the drain hole 312.

In some embodiments, as shown in FIGS. 1 and 2, drain hole 312 has a length D₂，D₂Satisfies the following conditions: d is not less than 8mm₂Less than or equal to 12 mm. For example, the drain hole 312 may have a length D₁10mm, when the height D of the drain hole 312₁When the value is taken within the value range, the liquid discharge hole 312 can be ensured to have the optimal liquid discharge effect, so that water flow can flow out from the liquid discharge hole 312 more quickly. Meanwhile, the device does not occupy too much space and is convenient to process. Here, "the length of the drain hole 312" means the left and right ends of the drain hole 312 as shown in FIG. 2The distance between the ends.

In some embodiments, the drain holes 312 may be circular holes, or the drain holes 312 may be elliptical holes, or the drain holes 312 may be oblong holes, or the drain holes 312 may be polygonal holes. Of course, the shape of the drain hole 312 may be flexibly set according to actual requirements, and is not limited herein.

For example, as shown in fig. 2, the drainage hole 312 may be a polygonal hole, so that an edge of the drainage hole 312 near the top surface can better fit with the top surface of the housing 10, and the size of the opening 311 of the drainage hole 312 is increased, so that the water flowing into the accommodating cavity 31 can rapidly flow out of the drainage hole 312. Therefore, the liquid discharge holes 312 with different shapes can be arranged according to actual conditions, so that the communication effect between the accommodating cavity 31 and the outside of the shell 10 is better, the water flow passing performance is improved, and the difficulty of the process of manufacturing the mounting part 30 and the liquid discharge holes 312 is reduced.

In some examples, as shown in fig. 1, 3 and 4, the case 10 may include a first case 11 and a second case 12, the second case 12 may be detachably coupled to the first case 11, and a drain hole 312 may be formed at a coupling portion of the first case 11 and the second case 12.

Specifically, the first casing 11 and the second casing 12 may be respectively disposed at the left and right ends of the cell module 20 as shown in fig. 1, the first casing 11 and the second casing 12 can be adapted to form a space for installing the cell module 20, and the cell module 20 is installed in the space defined by the first casing 11 and the second casing 12. The first housing 11 and the second housing 12 are detachably connected, for example, a buckle may be disposed on an inner side wall of the first housing 11, a clamping hole protruding out of the second housing 12 is disposed on an inner side wall of the second housing 12 corresponding to the inner side wall of the first housing 11, and after the first housing 11 is fitted with the second housing 12, the clamping hole and the buckle may be adapted to form a fixation of the first housing 11 and the second housing 12.

The drain hole 312 may be formed at the connection of the first housing 11 and the second housing 12. Therefore, the drainage hole 312 can be closer to the middle of the left-right direction in fig. 1, for example, so that water droplets on the first casing 11 and the second casing 12 can flow to the accommodating chamber 31 quickly and then flow out from the drainage hole 312, the residence time of the water droplets on the first casing 11 and the second casing 12 is reduced, and the waterproofness of the casing 10 is increased.

In some embodiments, as shown in FIG. 3, the bottom of the drain hole 312 may be formed on the top surface of the housing 10. For example, the top surface of the housing 10 may include a first inclined surface 111 and a second inclined surface 121 connected to each other, the first inclined surface 111 and the second inclined surface 121 may jointly form a drain hole 312, and both inclined surfaces are inclined downward in a direction in which the first inclined surface 111 and the second inclined surface 121 are away from each other, so that the drain hole 312 may be formed at the top end of the top surface of the housing 10, and the first inclined surface 111 and the second inclined surface 121 may discharge water droplets discharged from the drain hole 312 to both sides of the housing 10, may increase a discharge speed of the water droplets, and may reduce a residence time of the water droplets on the top surface of the housing 10. For example, when the housing 10 is opened, the opening slope may be formed, and the first slope 111 and the second slope 121 may be the opening slope, so that the processing process may be simplified, and the water drops may be rapidly discharged by the opening slope.

In some embodiments, the second housing 12 and the first housing 11 are sealingly connected. For example, a sealant may be applied or a sealing tape may be provided on the end surface of the first housing 11 that contacts the second housing 12. Therefore, the first casing 11 and the second casing 12 are hermetically connected to prevent water flowing through the joint between the second casing 12 and the first casing 11 from permeating into the casing 10 to affect the normal use of the cell module 20, so that the sealing performance of the battery 100 can be improved, and the service life of the battery 100 can be prolonged. Meanwhile, the dustproof function can be achieved.

In some embodiments, there are two mounting portions 30, and the battery 100 further includes a handle 40, and two ends of the handle 40 are respectively mounted in the corresponding accommodating cavities 31 through the corresponding openings 311.

As shown in fig. 1, two mounting portions 30 are disposed at the top of the housing 10, and each of the two mounting portions 30 defines a receiving cavity 31, an opening 311 formed on the receiving cavity 31, and a liquid discharge hole 312, and two ends of the handle 40 can respectively extend into the two receiving cavities 31 at the two ends and be mounted and connected. Thus, by providing two mounting portions 30 at the top of the housing 10, both ends of the handle 40 can be mounted on the two mounting portions 30, respectively, for the user to lift. At the same time, the structural strength of the connection between the first housing 11 and the second housing 12 is increased. For example, two drain holes 312 may be formed on the two mounting portions 30, and the two drain holes 312 may be formed opposite to each other to ensure uniform drainage at both ends.
