[0040] Embodiment 1

[0041] See also Figures 1 to 6 As shown, an embodiment of the present application provides a portable battery housing, comprising: a first shell portion 1, a tear strip 2 and a second shell portion 3; wherein the tear strip 2 is connected between the first shell portion 1 and the second shell portion 3, and the tear strip 2 extends along the circumference of the first shell portion 1 and the circumference of the second shell portion 3 at the same time, and when the tear strip 2 is torn off, the first shell portion 1 and the second shell portion 3 are at least partially separated.

[0042] Based on the structure described above, it can be known that when the battery needs to be disassembled, the tear strip 2 between the first shell part 1 and the second shell part 3 can be directly torn off, thereby replacing the complicated manual marking with a knife and tearing with pliers. The operation is simple and convenient, the work efficiency is high, and it is safer and more reliable, avoiding accidents.

[0043] In this embodiment, preferably, Figure 1 and Figure 2 As shown, a first tearing groove 4 is formed between the tear strip 2 and the first housing portion 1 , and the first tearing groove 4 extends along the circumference of the tear strip 2 .

[0044] According to the structure described above, a first tearing groove 4 is designed between the tear strip 2 and the first shell part 1 to form a thinning area, that is, a thinning area is formed between the tear strip 2 and the first shell part 1, thereby facilitating the separation of the tear strip 2 from the first shell part 1 along the first tearing groove 4.

[0045] In this embodiment, preferably, Figure 1 and Figure 2 As shown, a second tear groove 5 is formed between the tear strip 2 and the second housing portion 3 , and the second tear groove 5 extends along the circumference of the tear strip 2 .

[0046] According to the structure described above, it can be known that a first tearing groove 4 is designed between the tear strip 2 and the second shell part 3 to form a thinning area, that is, a thinning area is formed between the tear strip 2 and the second shell part 3, thereby facilitating the separation of the tear strip 2 from the second shell part 3 along this first tearing groove 4.

[0047] In this embodiment, preferably, Figure 2 As shown, a head end connecting groove 6 is formed at the head end of the tear strip 2, and both ends of the head end connecting groove 6 are respectively connected to the first tear groove 4 and the second tear groove 5.

[0048] According to the structure described above, by designing a connecting groove at the head end of the tear strip 2, that is, forming a thinning area at the head end of the tear strip 2, it is convenient to tear off the head end of the tear strip 2, and then to tear off the remaining part along the circumference of the tear strip 2.

[0049] In this embodiment, preferably, Figure 2 As shown, a tail end connecting groove is formed at the tail end of the tear strip 2, and the two ends of the tail end connecting groove are respectively connected with the first tear groove 4 and the second tear groove 5. It should be noted that: in this embodiment, the tail end connecting groove and the head end connecting groove 6 coincide with each other, so only the head end connecting groove 6 is shown, as will be described later.

[0050] According to the structure described above, it can be known that by designing a connecting groove at the tail end of the tear strip 2, that is, forming a thinning area at the tail end of the tear strip 2, it is convenient to tear off the tear strip 2 as a whole, avoiding it from remaining on the battery casing and causing interference and cutting to researchers when operating the interior of the battery casing.

[0051] Further, preferably, the tail end connecting groove extends along the height direction of the battery shell (the height direction of the first shell part 1 and the height direction of the second shell part 3 are the same as the height direction of the portable battery shell), and the tail end connecting groove is a semicircular arc groove.

[0052] In this embodiment, preferably, Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the tear strip 2 extends along the entire circumference of the first shell part 1 and the entire circumference of the second shell part 3 at the same time, so that the head end and the tail end of the tear strip 2 are connected, and the head end connecting groove 6 designed at the head end and the tail end connecting groove designed at the tail end coincide with each other. When the tear strip 2 is torn off, the first shell part 1 and the second shell part 3 are completely separated.

[0053] According to the structure described above, it can be known that the tear strip 2 can extend along the entire circumference of the opening at the top of the second shell part 3 (the opening at the top of the second shell part 3 mentioned here will only appear after the tear strip 2 is completely torn off and the first shell part 1 is completely separated from the second shell part 3). This can ensure that the first shell part 1 is completely separated from the second shell part 3, making it easier to inspect the interior of the battery and disassemble it later.

[0054] It should be noted that: not limited to the above-mentioned structure in which the tear strip 2 extends along the entire circumference of the first shell part 1 and the entire circumference of the second shell part 3, the following structure can also be adopted: Figure 7As shown, the tear strip 2 is only a part of the annular structure, that is, the tear strip 2 does not extend along the entire outer circumference of the first shell part 1 and the second shell part 3, and the head end and the tail end of the tear strip 2 are not connected, but are set at a certain distance. In this case, in addition to the aforementioned tear strip 2 structure, the first shell part 1 and the second shell part 3 are also connected by a part of the connecting shell part. In this case, when the tear strip 2 is torn, the first shell part 1 and the second shell part 3 are not completely separated, but are connected by the aforementioned connecting shell part. However, at this time, the first shell part 1 is open relative to the second shell part 3, so that the battery casing is in an open state, so that the interior thereof can also be inspected and subsequently disassembled, and correspondingly, the extension lengths of the aforementioned first tear groove 4 and the second tear groove 5 should be modified accordingly, and the specific design is based on actual needs.

[0055] In this embodiment, preferably, the wall thickness of the first shell part 1 and the second shell part 3 is the same, and the depths of the first tear groove 4, the second tear groove 5, the head end connecting groove 6 and the tail end connecting groove are equal and are all 1 / 2 of the wall thickness of the first shell part 1.

[0056] According to the structure described above, by using the tear groove and the connecting groove with the above-mentioned depth size, on the one hand, when the battery is used normally, it will not be damaged at the aforementioned tear groove and the connecting groove. On the other hand, when the battery needs to be disassembled, it is easier to tear off the tear strip 2.

[0057] In this embodiment, preferably, Figure 2 As shown, the portable battery housing further comprises a pull ring 8, one end of the pull ring 8 is fixed to the head end of the tear strip 2, and the other end of the pull ring 8 is a free end.

[0058] According to the structure described above, when disassembling the battery, one can hook the finger through the hook hole of the pull ring 8, and then pull it along the circumference of the second shell part 3, and finally complete the separation of at least part of the structure of the first shell part 1 and the second shell part 3, so as to facilitate operation on the inside of the battery.

[0059] In this embodiment, preferably, Figure 2 As shown, the pull ring 8 is connected to the tear strip 2 by riveting, so that the pull ring 8 is more firmly connected to the tear strip 2 and will not be pulled off the tear strip 2 to affect the subsequent tearing operation of the tear strip 2.

[0060] In this embodiment, preferably, Figures 2 to 4 As shown, the free end of the pull ring 8 is formed with a finger hook hole 81, the fixed end of the pull ring 8 is provided with a through hole 82, the tear strip 2 is provided with a riveted protrusion 21, and the through hole 82 on the pull ring 8 is riveted together with the riveted protrusion 21.

[0061] In this embodiment, preferably, Figure 1 , Figure 5 and Figure 6 As shown, the portable battery housing further includes a handle 9 , and the handle 9 is disposed on the outer wall of the second housing portion 3 .

[0062] According to the structure described above, the handle 9 is used to facilitate lifting of the battery, which is simple and convenient to operate, and solves the problem in the prior art that the single battery is large in size, heavy in weight, and has a smooth outer wall, which makes the grasping process very inconvenient.

[0063] In this embodiment, preferably, Figure 1 As shown, the handle 9 is rotatably connected to the second housing part 3 .

[0064] According to the structure described above, the handle 9 is designed to be rotatable. When the battery needs to be transported, the handle 9 can be rotated upward by a certain angle from the side that was originally against the battery shell to facilitate carrying the battery. After transporting to the target location, the handle 9 can be rotated and lowered to avoid interference.

[0065] In this embodiment, preferably, Figure 1 and Figure 3 As shown, the second shell part 3 is formed with a void avoidance groove 7, and the handle 9 is arranged in the void avoidance groove 7, and the two ends of the handle 9 are rotatably connected to the opposite side walls of the void avoidance groove 7 respectively. When the handle 9 is rotated and received in the void avoidance groove 7, the handle 9 does not protrude from the notch of the void avoidance groove 7.

[0066] According to the structure described above, when the handle 9 is rotated and lowered, it can be stored in the air-avoiding groove 7 to prevent it from protruding from the surface of the battery shell and avoiding interference with other external structures to affect the test.

[0067] Furthermore, preferably, there are two handles 9, which are respectively located on two opposite sides of the second housing portion 3. Correspondingly, each handle 9 is provided with a clearance groove 7. It can be seen that the two handles 9 ensure stability when lifting the battery.

[0068] Further, preferably, the handle 9 is arranged on the large side of the second housing portion 3, that is, the large side formed by the long sides and the high sides, so as to facilitate carrying.

[0069] Further, preferably, in order to facilitate holding, the handle 9 can be made of plastic.

[0070] It should be noted that the number of handles 9 is not limited to the two mentioned above, and can also be one, and the handle 9 is not limited to being arranged on the large surface side of the second shell part 3, and can also be designed on the small surface side, that is, the surface formed by the wide side and the high side.

[0071] In addition, the handle 9 is not limited to being designed on the second shell portion 3, but can also be designed on the first shell portion 1. When the handle 9 is designed on the first shell portion 1, specific reference can be made to the aforementioned situation where the handle 9 is designed on the second shell portion 3, and the design can be specifically based on actual needs.

[0072] In this embodiment, preferably, Figure 1 As shown, the first shell part 1 includes a cover ring 101 and a cover plate 102; wherein the cover ring 101, the tear strip 2 and the second shell part 3 are an integrated structure; the cover plate 102 and the cover ring 101 are connected by welding.
