Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without collision.

Referring to fig. 3 to 5, an embodiment of the present utility model provides a battery pack case 100. The battery pack case 100 is provided with a first recess 10 and a second recess 20. The first recess 10 includes a first side wall 101 and a first bottom wall 102. The first side wall 101 is disposed around the outer periphery of the first bottom wall 102. An end of the first side wall 101 facing away from the first bottom wall 102 forms an insertion port 1011. The second recess 20 includes a second side wall 201 and a second bottom wall 202. The second side wall 201 is located on a side of the first bottom wall 102 remote from the first side wall 101. The first bottom wall 102 is disposed around the outer periphery of the second side wall 201. The second side wall 201 is disposed around the second bottom wall 202, and the second bottom wall 202 is farther from the insertion port 1011 than the first bottom wall 102. The second bottom wall 202 is provided with a mounting opening 2021. The mounting port 2021 is used to mount the socket 200.

In use, the liquid needs to pass through the insertion port 1011 and the mounting port 2021 in sequence to enter the battery pack case 100 from the outside of the battery pack case 100, and in this process, the liquid flows through the first side wall 101, the first bottom wall 102, the second side wall 201 and the second bottom wall 202 in sequence, wherein the extending direction of the first side wall 101 and the extending direction of the second side wall 201 are approximately the directions in which the liquid enters the battery pack case 100 from the outside of the battery pack case 100, but the first bottom wall 102 and the second bottom wall 202 can form a barrier to the liquid in this direction, so that the moving speed of the liquid is slowed down, and the first side wall 101, the first bottom wall 102, the second side wall 201 and the second bottom wall 202 form step surfaces, so that the liquid cannot smoothly enter the battery pack case 100 through the first side wall 101 and the second side wall 201, thereby reducing the probability of the liquid entering the inside of the battery pack case 100. Meanwhile, the insertion opening 1011 is formed at one end of the first side wall 101 away from the first bottom wall 102, and the second bottom wall 202 is far away from the insertion opening 1011 than the first bottom wall 102, so that both the first side wall 101 and the second side wall 201 extend towards the inside of the battery pack case 100, the installation opening 2021 can be further far away from the insertion opening 1011, the distance from the insertion opening 1011 to the installation opening 2021 is prolonged, and the liquid is prevented from directly flying to the installation opening 2021 without flowing along the first side wall 101, the first bottom wall 102, the second side wall 201 and the second bottom wall 202, thereby further improving the waterproof effect of the battery pack case 100.

Referring to fig. 3 to 5, it can be appreciated that in some embodiments, when the battery pack case 100 is in use, the recess directions X of the first recess 10 and the second recess 20 are parallel and extend in the horizontal direction, that is, the first recess 10 and the second recess 20 are located at the side of the battery pack case 100, so that the liquid is prevented from being easily accumulated into the first recess 10 and the second recess 20 due to gravity when the battery pack case 100 is located at the top, and the convenience in use of the socket 200 when the battery pack case 100 is located at the bottom is avoided.

Referring to fig. 3-5, in some embodiments, the second bottom wall 202 is provided with an annular wall 2022. The annular wall 2022 is located on a side of the second bottom wall 202 adjacent to the first bottom wall 102, and is disposed around the outer periphery of the mounting opening 2021. When the liquid flows along the second side wall 201 toward the second bottom wall 202, the flow direction of the liquid is to flow toward the inside of the battery pack case 100; the annular wall 2022 is disposed around the periphery of the mounting opening 2021 such that the liquid flows from the second bottom wall 202 to the mounting opening 2021 through the annular wall 2022; and the annular wall 2022 is disposed on one side of the second bottom wall 202 near the first bottom wall 102, and both the annular wall 2022 and the second side wall 201 are disposed on one side of the second bottom wall 202 near the first bottom wall 102, so that when the liquid flows from the second bottom wall 202 to the annular wall 2022, the flowing direction of the liquid is reversed and flows to the outside of the battery pack case 100, thereby blocking the liquid, making the liquid unable to directly enter the mounting opening 2021, and improving the waterproof effect of the battery pack case 100.

Referring to fig. 3, it can be appreciated that in some embodiments, an end of the annular wall 2022 remote from the second bottom wall 202 is closer to the second bottom wall 202 than an end of the second side wall 201 remote from the second bottom wall 202, so as to avoid that the extending length of the annular wall 2022 in the recess direction X of the second recess 20 is too long, which may hinder the use of the socket 200.

Referring to fig. 4 and 5, in some embodiments, the second bottom wall 202 is provided with a connection hole 2023. The connection hole 2023 is located outside the annular wall 2022 as compared to the mounting port 2021. The battery pack case 100 further includes a connection member 30.

A connection hole 2023 is provided in the second bottom wall 202, and the connection hole 2023 is perforated by the connection member 30 to connect the socket 200, so as to fix the socket 200 on the side of the second bottom wall 202 facing away from the first bottom wall 102. The connection hole 2023 is located outside the annular wall 2022 with respect to the mounting hole 2021, so that the annular wall 2022 can be attached to the socket 200 located at the mounting hole 2021 as much as possible, and the waterproof effect between the annular wall 2022 and the socket 200 is improved. Meanwhile, the avoidance groove 2011 which is communicated with the connecting hole 2023 and the first bottom wall 102 is formed, so that the caliber of the second concave part 20 is reduced as much as possible on the basis of facilitating the connection of the connecting piece 30 with the socket 200, and the waterproof effect is improved. It is understood that in some embodiments, the connector 30 includes, but is not limited to, screws, bolts, snaps, and the like.

Referring to fig. 3, in some embodiments, an end of the first sidewall 101 facing away from the first bottom wall 102 is flush with a surface of the battery pack housing 100; and/or the end of the second side wall 201 facing away from the second bottom wall 202 is flush with the first bottom wall 102. The first side wall 101 and the second side wall 201 need to have a certain extension length in the concave direction X, one end of the first side wall 101, which is away from the first bottom wall 102, flushes the surface of the battery pack housing 100, and one end of the second side wall 201, which is away from the second bottom wall 202, flushes the first bottom wall 102, so that the first bottom wall 102 and the second bottom wall 202 are far away from the surface of the battery pack housing, the distance from the insertion port 1011 to the mounting port 2021 is prolonged, and the waterproof effect of the battery pack housing 100 is improved. Meanwhile, the second side wall 201 is flush with the first bottom wall 102, so that the second side wall 201, the first bottom wall 102 and the first side wall 101 can be prevented from being matched to form a groove, liquid, dust and the like collected in the first bottom wall 102 can be cleaned conveniently, and liquid, dust and the like are prevented from entering the mounting opening 2021 due to untimely cleaning.

Referring to fig. 3-5, in some embodiments, the first side wall 101, the first bottom wall 102, the second side wall 201, the second bottom wall 202, and the annular wall 2022 are integrally formed.
