In an embodiment, referring to fig. 2, 3 and 7, the battery pack 100 further includes: a sealing member 140, the sealing member 140 being disposed around the communication hole 1132, and the sealing member 140 being disposed between the sealing plate 130 and the first frame portion 1131; the sealing member 140 is provided with a groove 141 at a side close to the opening, and the waterproof portion 114 is provided close to the opening 1133 with respect to the groove 141 in the second direction Z.
The sealing element 140 may be made of a polymer material with better rebound resilience, for example: o-rings, rubber strips, etc., but are not limited thereto.
It can be appreciated that, since the sealing element 140 is provided with the groove 141 to avoid part of the structure on the first frame portion 1131, when a raining or splashing situation occurs, rainwater may flow from the top of the cover plate to the groove 141, and is difficult to volatilize in a short time, so that the rainwater flows from the groove 141 to the inside of the case, and the electrical element inside the case is short-circuited, insulated and other failure problems are caused, thereby affecting the safety of the battery pack.
According to the application, the waterproof part 114 is arranged close to the opening 1133 relative to the groove 141, so that when raining, splashing or the like occurs, rainwater is guided by the waterproof part 114, thereby avoiding short circuit and insulation of electric elements caused by rainwater converging at the groove 141 and flowing into the accommodating cavity 111, ensuring normal operation of components in the battery pack 100 and improving the safety performance of the battery pack 100.
Further, referring to fig. 7, a seal groove 131 is formed on the seal plate 130, the seal groove 131 extends along the circumferential direction of the seal plate 130, the seal element 140 is adapted to the seal groove 131, and the seal element 140 is embedded in the seal groove 131.
The adaptation of the sealing element 140 to the sealing groove 131 means that the sealing groove 131 is identical to the sealing element 140 in shape and size.
In the application, the sealing groove 131 is formed on the sealing plate 130, so that a positioning structure is formed between the sealing plate 130 and the sealing element 140 by utilizing the cooperation between the sealing element 140 and the sealing groove 131, thereby facilitating the assembly and fixation of the sealing plate 130 and improving the overall assembly efficiency of the battery pack 100; meanwhile, the sealing element 140 is embedded in the sealing groove 131, so that the sealing effect of the sealing element 140 is improved, and the overall sealing performance of the battery pack 100 is ensured.

That is, the maximum dimension L 1 mm of the waterproof portion 114 in the first direction X is greater than the maximum dimension L 2 mm of the sealing plate 130 in the first direction X, so as to ensure the waterproof effect of the waterproof portion 114, ensure that rainwater cannot collect at the sealing plate 130, and further improve the safety performance of the battery pack.
The maximum dimension L 1 mm of the waterproof portion 114 in the first direction X may be obtained by measuring the dimensions of the waterproof portion 114 at different positions in the first direction X by a measuring tool multiple times and calculating an average value. The measuring tool may be any one of a ruler or a vernier caliper, but is not limited thereto.
The maximum dimension L 2 mm of the sealing plate 130 in the first direction X can be obtained by measuring the dimensions of the sealing plate 130 at different positions in the first direction X by a measuring tool a plurality of times and calculating an average value. The measuring tool may be any one of a ruler or a vernier caliper, but is not limited thereto.
Specifically, in the present application, the maximum dimension L 1 mm of the waterproof portion 114 in the first direction X may be adjusted to ensure that the waterproof portion 114 has a better waterproof effect in different application scenarios. When the battery pack 100 is applied to a rainy environment, the waterproof part 114 may be designed to be longer in the maximum dimension L 1 mm of the first direction X, so that the waterproof part 114 has a sufficient length in the first direction X, guaranteeing the waterproof effect of the waterproof part 114. When the battery pack 100 is applied to an environment with less rainwater, the maximum dimension L 1 mm of the waterproof part 114 in the first direction X can be designed to be shorter, so that the space occupied by the waterproof part 114 is reduced while the waterproof effect of the waterproof part 114 is ensured, and the overall layout design of the battery pack 100 is facilitated.
In order to further ensure the waterproof effect of the waterproof portion 114, in one embodiment, referring to fig. 5, the maximum dimension of the waterproof portion 114 in the third direction Y is L 3 mm, the maximum dimension of the sealing plate 130 in the third direction Y is L 4 mm, which satisfies the following: l 3≥L4. That is, the maximum dimension L 3 mm of the waterproof part 114 in the third direction Y is not less than the maximum dimension L 4 mm of the sealing plate 130 in the third direction Y, so that when the waterproof part 114 guides rainwater, the rainwater flowing out along the two ends of the waterproof part 114 in the third direction Y cannot flow onto the sealing plate 130, the waterproof effect of the waterproof part 114 is further ensured, and the safety performance of the battery pack 100 is improved.
Wherein, the maximum dimension L 3 mm of the waterproof part 114 in the third direction Y can be obtained by measuring the thickness of the waterproof part 114 at different positions in the third direction Y by a measuring tool a plurality of times and calculating an average value. The measuring tool may be any one of a ruler or a vernier caliper, but is not limited thereto.
The maximum dimension L 4 mm of the sealing plate 130 in the third direction Y can be obtained by measuring the thickness of the sealing plate 130 at different positions in the third direction Y by a measuring tool a plurality of times and calculating an average value. The measuring tool may be any one of a ruler or a vernier caliper, but is not limited thereto.
In an embodiment, referring to fig. 5 again, the waterproof portion 114 has a first surface 1141 and a second surface 1142 opposite to each other in the second direction Z, and the first surface 1141 is disposed away from the communication hole 1132 opposite to the second surface 1142, i.e. the first surface 1141 is used for waterproof and guiding of rainwater. Specifically, the middle position of the first surface 1141 protrudes in a direction away from the communication hole 1132, that is, the middle position of the first surface 1141 forms a protruding structure, so that when rainwater is collected on the first surface 1141, the rainwater can flow from a side close to the first frame portion 1131 to a side far away from the first frame portion 1131 in the first direction X under the action of gravity of the rainwater, and in the third direction Y, the rainwater can flow from the middle position of the first surface 1141 to two ends, so that directional diversion of the rainwater is realized, and the waterproof effect of the waterproof portion 114 is improved.
Referring to fig. 5, the first surface 1141 is divided into a first curved surface section 11411 and a second curved surface section 11412 along a third direction Y, a distance between the first curved surface section 11411 and the sealing plate 130 in a second direction Z increases along a direction close to the second curved surface section 11412, and a distance between the second curved surface section 11412 and the sealing plate 130 in the second direction Z increases along a direction close to the first curved surface section 11411, so that the first surface 1141 forms a convex structure at a connection position between the first curved surface section 11411 and the second curved surface section 11412, and when rainwater is collected on the first surface 1141, in the third direction Y, the rainwater can flow from a middle position of the first surface 1141 to two ends, thereby realizing directional diversion of the rainwater and improving a waterproof effect of the waterproof part 114.
Specifically, in the present application, the curvature of the first curved surface section 11411 and the second curved surface section 11412 can be correspondingly adjusted, for example, when the battery pack 100 is applied to a rainy environment, as shown in fig. 8, the curvature corresponding to the first curved surface section 11411 and the curvature corresponding to the second curved surface section 11412 can be designed to be larger, so as to improve the falling speed of the rainwater in the first curved surface section 11411 and the second curved surface section 11412, and achieve a better diversion effect. When the battery pack 100 is applied to an environment with less rainwater, as shown in fig. 5, the radian corresponding to the first curved surface section 11411 and the radian corresponding to the second curved surface section 11412 can be designed smaller, so that the flow guiding effect of the first curved surface section 11411 and the second curved surface section 11412 is satisfied, and meanwhile, the processing and forming of the first curved surface section 11411 and the second curved surface section 11412 are facilitated, and further the processing and forming of the waterproof part 114 are facilitated.
Further, in an embodiment, referring to fig. 6, in the first direction X, the first surface 1141 has a third curved surface section 11413, and a distance between the third curved surface section 11413 and the sealing plate 130 decreases along a direction away from the first frame portion 1131, that is, an end of the third curved surface section 11413, which is close to the first frame portion 1131, in the first direction X is protruded, so that when rainwater is collected on the first surface 1141, the rainwater can flow from a side, which is close to the first frame portion 1131, to a side, which is far from the first frame portion 1131, in the first direction X under the action of gravity of the rainwater, so as to achieve directional diversion of the rainwater, and improve the waterproof effect of the waterproof portion 114.
Specifically, in the present application, the curvature of the third curved surface section 11413 can be correspondingly adjusted, for example, when the battery pack 100 is applied to a rainy environment, as shown in fig. 9, the curvature of the third curved surface section 11413 can be designed to be larger, so as to improve the falling speed of the rainwater in the third curved surface section 11413, and achieve a better diversion effect. When the battery pack 100 is applied to an environment with less rainwater, as shown in fig. 6, the radian of the third curved surface section 11413 can be designed smaller, so that the flow guiding effect of the first curved surface section 11411 and the second curved surface section 11412 is satisfied, and meanwhile, the processing and forming of the third curved surface section 11413 are facilitated, and further, the processing and forming of the waterproof part 114 are facilitated.
In one embodiment, the present application is adaptable to the distance between the second surface 1142 and the sealing plate 130 in the second direction Z. Specifically, when the battery pack 100 is applied to a rainy environment, as shown in fig. 8 and 9, the distance between the second surface 1142 and the sealing plate 130 in the second direction Z may be designed to be smaller, so as to ensure that the sealing plate 130 is completely under the complete waterproof shelter of the waterproof portion 114, and improve the isolation and waterproof effect of the waterproof portion 114. When the battery pack 100 is applied to an environment with less rainwater, as shown in fig. 5 and 6, the distance between the second surface 1142 and the sealing plate 130 in the second direction Z may be designed to be moderate, thereby satisfying the waterproof effect of the waterproof part 114 while facilitating the processing and forming of the waterproof part 114 and facilitating the assembly of the battery pack 100.
In an embodiment of the present application, the present application further provides an electric device, including the battery pack 100 as set forth in any one of the above, where the battery pack 100 is used as a power supply of the electric device. The electric equipment can be, but is not limited to, mobile equipment (such as mobile phones, notebook computers and the like), electric vehicles (such as pure electric vehicles, hybrid electric vehicles, plug-in hybrid electric vehicles, electric bicycles, electric scooters, electric golf carts, electric trucks and the like), electric trains, ships, satellites, energy storage systems and the like.
The above steps are presented merely to aid in understanding the method, structure, and core concept of the application. It will be apparent to those skilled in the art that various changes and modifications can be made to the present application without departing from the principles of the application, and such changes and modifications are intended to be included within the scope of the appended claims.
