[0028] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below with specific embodiments:

[0029] Such as Figure 1 And Figure 2As shown, the lifting battery case 100 of an embodiment includes a case 110, a lifting member 120, a load-bearing member 130, and a positioning member 140. The lifting member 120 is disposed outside the case 110. An installation position 1110 is formed inside the case 110. The installation position 1110 is disposed close to the lifting member 120. The positioning member 140 is fixedly disposed on the installation position 1110. The load-bearing member 130 is disposed through the installation notch 1121 of the case 110. The first end of the load-bearing member 130 is connected to the lifting member 120. The second end of the load-bearing member 130 extends toward the installation position 1110 and is connected to the positioning member 140.

[0030] It can be understood that since the load-bearing member 130 is disposed through the installation notch 1121 of the case 110, the first end of the load-bearing member 130 can extend outside the case 110 and be connected to the lifting member 120. When a user pulls the lifting member 120, the lifting member 120 can pull the load-bearing member 130. At the same time, since the second end of the load-bearing member 130 can extend toward the inside of the case 110 into the installation position 1110, the second end of the load-bearing member 130 can be connected to the positioning member 140 fixed on the installation position 1110, so that the load-bearing member 130 can conduct force to the inside of the case 110, and finally the lifting member 120 outside the case 110 can lift the case 110.

[0031] It can be understood that compared with the prior art, after the battery module is placed in the case 110 of the above-mentioned lifting battery case 100, since the load-bearing member 130 passes through the installation notch 1121 of the case 110, and the second end of the load-bearing member 130 extends into the inside of the case 110 and is connected to the positioning member 140, the second end of the load-bearing member 130 can be more firmly constrained inside the case 110, so that the load-bearing member 130 has a stronger load-bearing capacity and is less likely to break during handling, and finally can be used more stably.

[0032] Combined with Figure 1 With Figure 3 As shown, in one embodiment, the first end of the load-bearing member 130 passes through the lifting member 120 and is connected to the case 110. It can be understood that since the first end of the load-bearing member 130 passes through the lifting member 120, the lifting member 120 and the load-bearing member 130 can be more tightly connected. In this embodiment, the load-bearing member 130 is a rigid rod. The first end of the rigid rod passes through the lifting member 120 and is embedded in the outer wall of the case 110. The first end of the rigid rod passes through the case 110 and is connected to the positioning member 140, thereby further improving the load-bearing capacity of the load-bearing member 130. In other embodiments, the load-bearing member 130 can also be a soft belt, etc. Here, it is not limited, and those skilled in the art can make replacements according to needs.

[0033] Combined with Figure 2 With Figure 3As shown, in one embodiment, the second end of the load-bearing member 130 is embedded in the positioning member 140. It can be understood that since the second end of the load-bearing member 130 is embedded in the positioning member 140, the positioning member 140 and the load-bearing member 130 can be more tightly connected. Combining Figure 3 As shown, in this embodiment, an embedding hole 1410 is formed in the positioning member 140. The load-bearing member 130 is a rigid rod. The rigid rod penetrates through the housing 110, and the second end of the rigid rod is embedded in the embedding hole 1410, thereby fixing the second end of the rigid rod and making the installation of the rigid rod more firm.

[0034] Combining Figure 3 As shown, in one embodiment, a water-blocking layer 1111 is provided in the installation position 1110. It can be understood that since the water-blocking layer 1111 is provided in the installation position 1110, when the moisture outside the housing 110 enters the installation position 1110 inside the housing 110 along the load-bearing member 130, the moisture can be blocked by the water-blocking layer 1111, thereby enhancing the waterproof performance of the housing 110.

[0035] Combining Figure 3 As shown, in this embodiment, the water-blocking layer 1111 covers the positioning member 140. It can be understood that since the water-blocking layer 1111 covers the positioning member 140, when the moisture outside the housing 110 seeps to the surface of the positioning member 140 along the load-bearing member 130, the moisture can be blocked by the water-blocking layer 1111, so that the battery module in the housing 110 can be isolated from the moisture. As Figure 3 shown, specifically, the water-blocking layer 1111 can be a waterproof glue layer. A glue application groove 1112 is formed at the installation position 1110. The positioning member 140 is arranged in the glue application groove 1112; the second end of the load-bearing member 130 passes through the groove wall of the glue application groove 1112 and is connected to the positioning member 140; the waterproof glue layer covers the positioning member 140 and fills the glue application groove 1112. The positioning member 140 can not only be more firmly glued to the glue application groove 1112 through the waterproof glue layer, but also achieve an IPX7-level waterproof effect by covering the positioning member 140. In other embodiments, the water-blocking layer 1111 can also be a water-absorbing cotton layer, etc. Here, it is not limited, and those skilled in the art can make replacements according to needs.

[0036] Combining Figure 3 As shown, in one embodiment, the positioning member 140 is fixedly arranged on the installation position 1110. It can be understood that since the positioning member 140 is fixedly arranged on the installation position 1110, the positioning member 140 and the installation position 1110 can be tightly connected, so that the second end of the load-bearing member 130 can be more strongly constrained by the positioning member 140, further improving the load-bearing capacity of the load-bearing member 130. Specifically, the positioning member 140 can be screwed, snapped or welded to the installation position 1110. Of course, it is not limited here, and those skilled in the art can make replacements according to needs.

[0037] Combined with Figure 2 As shown, in this embodiment, the positioning member 140 and the housing 110 are engaged with each other. It can be understood that since the positioning member 140 and the housing 110 are engaged with each other, the position of the positioning member 140 in the installation position 1110 can be fixed, and it is less likely to move up and down in the installation position 1110 when the lifting member 120 is pulled.

[0038] Combined with Figure 2 As shown, specifically, a limiting groove 1420 is formed on the positioning member 140, and a limiting block 1113 protrudes into the limiting groove 1420 from the housing 110. It can be understood that since the limiting block 1113 protrudes into the limiting groove 1420 from the housing 110, the housing 110 can be closely fitted with the limiting groove 1420, so that the position of the positioning member 140 in the installation position 1110 is kept fixed. Among them, the limiting block 1113 is screwed to the bottom of the limiting groove 1420, so that the limiting block 1113 and the limiting groove 1420 are more closely fitted. In some other embodiments, the positioning member 140 is provided with a convex platform, and the convex platform is fitted into a groove (not shown) in the installation position 1110.

[0039] Combined with Figure 1 As shown, in one of the embodiments, a receiving groove 1120 is formed on the outer side of the housing 110, and the receiving groove 1120 is used to receive the lifting member 120. It can be understood that when the lifting member 120 is not in use, the lifting member 120 can be received in the receiving groove 1120 to reduce space occupation. As Figure 1 As shown, in this embodiment, the lifting member 120 is a handle, and both ends of the handle are respectively arranged in the receiving groove 1120. The number of the load-bearing members 130, the positioning members 140 and the installation positions 1110 are all two, and each installation position 1110 is arranged near one end of the handle. Each end of the handle is rotatably connected to the corresponding positioning member 140 through the corresponding load-bearing member 130. Furthermore, after use, the handle can be rotated so that the handle is received in the receiving groove 1120. In some other embodiments, the lifting member 120 can be a pulling belt, a pulling ring, etc. Of course, it is not limited here, and those skilled in the art can make replacements according to needs.

[0040] Combined with Figure 1 As shown, further, a limiting member 1122 is arranged in the receiving groove 1120, and the limiting member 1122 is used to abut against the lifting member 120. It can be understood that since the limiting member 1122 is arranged in the receiving groove 1120, when the lifting member 120 is received in the receiving groove 1120, the lifting member 120 can be abutted by the limiting member 1122, so that the lifting member 120 can be kept in the receiving groove 1120. Specifically, the limiting member 1122 and the groove wall of the receiving groove 1120 are integrally formed.

[0041] Combined with Figure 1 And Figure 3As shown, in one of the embodiments, the installation notch 1121 is formed on the wall of the receiving groove 1120 and extends to the notch of the receiving groove 1120; the load-bearing member 130 passes through the installation notch 1121 and thus penetrates the housing 110. It can be understood that since the installation notch 1121 extends from the notch of the receiving groove 1120 towards the lifting member 120, the load-bearing member 130 can be quickly disassembled and assembled through the installation notch 1121, that is, the load-bearing member 130 can quickly penetrate the housing 110 through the installation notch 1121. In this embodiment, the pull-up battery case 100 further includes a filling member 150, and the filling member 150 is filled in the installation notch 1121. It can not only fill the installation notch 1121 through the filling member 150 to restrict the position of the load-bearing member 130, but also prevent external moisture from entering, further improving the waterproof performance. Specifically, the filling member 150 can be a silicone member or a sponge member, etc. Of course, it is not limited here, and those skilled in the art can also make replacements according to needs.

[0042] The present disclosure also provides a battery pack, including a battery module and the pull-up battery case 100 of any of the above embodiments, and the battery module is placed in the pull-up battery case 100. It can be understood that by applying the pull-up battery case 100 of the present disclosure in the battery pack, when the battery module is placed in the pull-up battery case 100, the battery pack can be conveniently lifted for handling by pulling the lifting member 120. In some other embodiments, the housing 110 of the above pull-up battery case 100 can be a part of a two-wheeled vehicle, and the two-wheeled vehicle includes an electric bicycle, an electric motorcycle, etc.

[0043] Compared with the prior art, the present disclosure has at least the following advantages:

[0044] 1) Since the load-bearing member 130 is arranged to penetrate the installation notch 1121 of the housing 110, the first end of the load-bearing member 130 can extend outside the housing 110 and be connected to the lifting member 120. When the user pulls the lifting member 120, the lifting member 120 can pull the load-bearing member 130. At the same time, since the second end of the load-bearing member 130 can extend towards the inside of the housing 110 into the installation position 1110, the second end of the load-bearing member 130 can be connected to the positioning member 140 fixed on the installation position 1110, so that the load-bearing member 130 can conduct the force to the inside of the housing 110, and finally the lifting member 120 outside the housing 110 can lift the housing 110.

[0045] 2) Compared with the prior art, after the battery module is placed into the housing 110 of the above-mentioned lifting type battery case 100, since the load-bearing member 130 passes through the installation notch 1121 of the housing 110, and the second end of the load-bearing member 130 extends into the inner side of the housing 110 and is connected to the positioning member 140, the second end of the load-bearing member 130 can be more firmly constrained inside the housing 110, so that the load-bearing member 130 has a stronger load-bearing capacity, is less likely to break during handling, and can ultimately be used more stably.

[0046] The above-described embodiments merely represent several implementation manners of the present disclosure. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
