The first connecting edge 112 is located at the opening of the accommodating portion 111 and located at least one side of the accommodating portion 111 in the circumferential direction, for example, only one side of the opening in the circumferential direction may be provided with the first connecting edge 112, both sides of the opening in the left-right direction may be provided with the first connecting edge 112, both sides of the opening in the front-rear direction may be provided with the first connecting edge 112, and both sides of the opening in the front-rear direction and both sides of the opening in the left-right direction may be provided with the first connecting edge 112.

For example, as shown in fig. 6, when the top cover 2 is formed in a flat plate shape, when the top cover 2 is covered on the opening side with the bottom case 11, a part of the top cover 2 is covered on the upper side of the accommodation groove, and the other part is protruded beyond the accommodation groove in the horizontal direction, and the part can be connected with the first connection side 112 of the bottom case 11 as the second connection side 121; alternatively, the top cover 2 may be configured to have a receiving portion and a second connecting edge 121, where the receiving portion is formed with a receiving groove, and when the top cover 2 is covered on the bottom shell 11, the receiving portion of the top cover 2 is opposite to the receiving portion 111 of the bottom shell 11, and the receiving groove together form a battery cell receiving cavity for receiving a battery cell, and the second connecting edge 121 is located on a peripheral side of the receiving portion and opposite to and attached to the first connecting edge 112.

It should be noted that, the widths of the first connecting edge 112 and the second connecting edge 121 may be equal or different, and the widths of the first connecting edge 112 and the second connecting edge 121 may be reasonably selected according to actual needs.

The housing 1 has a connection flange 10, the connection flange 10 may be formed by at least one of the second connection edge 121 and the first connection edge 112, the connection flange 10 is provided with a connection structure 101, and the connection structure 101 may be configured to be detachably connected with an assembly structure of the electronic device. For example, the connection structure 101 may be formed into a connection hole, a clamping groove, a buckle or other structures, and an assembly structure is disposed in a battery compartment of the electronic device, and the assembly structure may be in plug-in fit, clamping fit, hooking fit, or the like with the connection structure 101, or may be in other fit manners, so as to realize detachable connection with the connection structure 101, thereby realizing mounting and fixing of the battery 100 on the electronic device.

According to the housing 1 of the battery 100 of the embodiment of the utility model, the connection flange 10 is formed by at least one of the second connection edge 121 and the first connection edge 112, and since the connection flange 10 is provided with the connection structure 101, the connection structure 101 can be detachably connected with the assembly structure of the electronic device, compared with the scheme that the battery is fixed in the battery compartment by means of adhesive in the related art, the electronic device is easier to assemble and disassemble the battery 100 and replace, other elements are prevented from being damaged when the battery 100 is replaced, and meanwhile, the battery 100 has enough installation stability.

In some embodiments, referring to fig. 1-12, the attachment cuff 10 may be formed by folding a portion of the structure of at least one of the second attachment edge 121 and the first attachment edge 112 toward a direction approaching the side wall of the receiving slot. In other words, the connecting flange 10 of the present embodiment has a folded structure. For example, only a part of the first connecting edge 112 may be folded in a direction toward the side wall of the accommodating groove to form the connecting flange 10 of the housing 1, only a part of the second connecting edge 121 may be folded in a direction toward the side wall of the accommodating groove to form the connecting flange 10 of the housing 1, or the second connecting edge 121 and the first connecting edge 112 may be folded together in a direction toward the side wall of the accommodating groove to form the connecting flange 10 of the housing 1.

As can be appreciated, since the connection flange 10 formed by folding is closer to the side wall of the receiving groove, the connection flange 10 can strengthen the structural strength of the side portion of the case 1, and in addition, the size of the battery 100 in the horizontal direction can be reduced, thereby reducing the volume of the battery 100 and contributing to an improvement in the energy density of the battery 100.

In some embodiments, referring to fig. 8, the first connecting edge 112 and the second connecting edge 121 have the same width, that is, the edges of the first connecting edge 112 and the second connecting edge 121 are flush, at this time, the first connecting edge 112 and the second connecting edge 121 are folded together toward a direction close to the side wall of the receiving groove to form the connecting flange 10 of the housing 1, and at this time, the connecting structure 101 is formed on the sealed edge formed by the first connecting edge 112 and the second connecting edge 121 together. Because the connection flange 10 is formed by folding the first connection edge 112 and the second connection edge 121 after being overlapped, the connection flange 10 has higher structural strength, is not easy to deform, can be better connected with the assembly structure of the electronic equipment, and is also beneficial to enhancing the structural strength of the side part of the shell 1.

In other embodiments, referring to fig. 9-12, the widths of the first connecting edge 112 and the second connecting edge 121 are unequal, and the one of the first connecting edge 112 and the second connecting edge 121 having the greater width has an edge portion beyond the one of the lesser width, the edge portion being folded over and constituting the connecting flange 10.

For example, as shown in fig. 9, the width of the second connecting edge 121 is larger than the width of the first connecting edge 112, and the portion of the second connecting edge 121 beyond the first connecting edge 112 in the width direction is folded over and constitutes the connecting flange 10 of the housing 1, and at this time, the connecting structure 101 is formed only on the connecting flange 10 constituted by the portion of the second connecting edge 121 beyond the first connecting edge 112 in the width direction.

Or as shown in fig. 10, the width of the first connecting edge 112 is larger than the width of the second connecting edge 121, and the portion of the first connecting edge 112 beyond the second connecting edge 121 in the width direction is folded over and constitutes the connecting flange 10 of the housing 1, and at this time, the connecting structure 101 is formed only on the connecting flange 10 constituted by the portion of the first connecting edge 112 beyond the second connecting edge 121 in the width direction.

In summary, in the present embodiment, only the larger one of the first connecting edge 112 and the second connecting edge 121, which exceeds the smaller one, is folded to form the connecting flange 10 of the housing 1, and the folding process is easier to be performed due to the thinner thickness of the connecting flange 10, so that the process difficulty is reduced.

In some embodiments, referring to fig. 11 and 12, it is contemplated that the structural strength of the attachment cuff 10 is weaker when formed by folding over only one of the first and second attachment edges 112, 121 than the structural strength of the attachment cuff 10 formed by folding over the first and second attachment edges 112, 121 together. Therefore, in order to prevent the connection flange 10 from being deformed and to enhance the structural strength of the connection flange 10, the extension supporting portion 13 may be formed on the smaller one of the first connection edge 112 and the second connection edge 121, and the extension supporting portion 13 may be attached to the connection flange 10 and may be staggered from the connection structure 101, so that the connection structure 101 and the assembly structure may be prevented from being connected and engaged by the extension supporting portion 13 while the structural strength of the connection flange 10 is increased.

For example, as shown in fig. 11, when the width of the first connecting edge 112 is greater than the width of the second connecting edge 121, the connecting flange 10 is formed by folding over the portion of the first connecting edge 112 beyond the second connecting edge 121, at this time, an extending support portion 13 may be formed on the second connecting edge 121, the extending direction of the extending support portion 13 is parallel to the extending direction of the connecting flange 10, the extending support portion 13 is attached to the connecting flange 10, at this time, the extending support portion 13 is located outside the folded portion, and the extending support portion 13 may support the connecting flange 10.

Or as shown in fig. 12, when the width of the second connecting edge 121 is greater than the width of the first connecting edge 112, the connecting flange 10 is formed by folding over the portion of the second connecting edge 121 beyond the first connecting edge 112, at this time, an extending support portion 13 may be formed on the first connecting edge 112, the extending direction of the extending support portion 13 is parallel to the extending direction of the connecting flange 10, the extending support portion 13 is attached to the connecting flange 10, at this time, the extending support portion 13 is located inside the folded portion, and the extending support portion 13 may support the connecting flange 10.

In some alternative embodiments, when the connection flange 10 is of a single-layer structure, that is, the connection flange 10 is formed by folding only a part of the structure of the first connection edge 112 or the second connection edge 121, a reinforcing structure such as a reinforcing rib, a reinforcing ridge, or the like may be provided on the connection flange 10, so as to enhance the structural strength of the connection flange 10, prevent the connection flange 10 from being deformed, and ensure the assembly accuracy of the connection structure 101 and the assembly structure.

In some embodiments, referring to fig. 2, the connection flange 10 extends obliquely with respect to the sidewall of the accommodating groove, for example, the connection flange 10 may extend away from the sidewall of the accommodating groove with respect to the sidewall of the accommodating groove, or may extend toward the sidewall of the accommodating groove with respect to the sidewall of the accommodating groove, so that the connection flange 10 is various in form and can meet the connection fitting requirements of different assembly structures.

In some embodiments, referring to fig. 2, the free end of the connection flange 10 faces the side wall of the receiving groove, and the connection flange 10 and the side wall of the receiving groove together define a relief gap, in which the width of the relief gap gradually becomes smaller in the direction from the top cover 2 toward the bottom wall of the bottom case 11. The mounting structure is configured to couple to the connection structure 101 and extend into the relief gap. In this way, the connecting flange 10 is closer to the side wall of the accommodating groove, the structural strength of the side part of the housing 1 can be better improved, the strength of the connecting flange 10 can be improved, the connecting flange is not easy to deform, in addition, the width of the battery 100 is reduced, the energy density of the battery 100 is improved, and the assembling structure is convenient to connect and match with the connecting structure 101.

In some embodiments, referring to fig. 13, the distance s between the beginning of the connecting flange 10 and the side wall of the receiving groove ranges from: the distance s between the starting end of the connecting flange 10 and the side wall of the receiving groove may be 0.5mm, 1mm, 1.5mm, 2mm, 3mm or 3.5mm, for example, and the distance s between the starting end of the connecting flange 10 and the side wall of the receiving groove may be appropriately selected within the above range as needed. In this way, when the interval s between the starting end of the connection flange 10 and the side wall of the accommodating groove is too small, for example, less than 0.5mm, the connection flange 10 is close to the side wall of the accommodating groove, so that the turnover angle of the first connection edge 112 and the second connection edge 121 is too large, the stress is large, structural damage and even breakage can occur, and when the interval s between the starting end of the connection flange 10 and the side wall of the accommodating groove is too large, for example, greater than 3.5mm, the size of the housing 1 is too large, which is unfavorable for improving the energy density of the battery 100.

In some embodiments, referring to fig. 2, the range of the included angle α between the extending direction of the connecting flange 10 and the plane of the side wall of the accommodating groove is: 0 ° < α <90 °, that is, the extending direction of the connecting flange 10 and the plane of the side wall of the receiving groove form an acute angle. For example, the angle α between the extending direction of the connecting flange 10 and the plane of the side wall of the receiving groove may be 10 °, 30 °, 50 °, 70 °, 85 °, and the like, and α may be reasonably selected within the above range. So, both can avoid connecting the turn-ups 10 and be 0 with the planar contained angle alpha in lateral wall place of holding tank when, connect turn-ups 10 and the lateral wall of holding tank laminating completely, lead to the assembly structure unable effective cooperation with connection structure 101, can avoid connecting the turn-ups 10 again and the planar contained angle alpha in lateral wall place of holding tank too big, lead to the holistic width dimension grow of battery 100, be unfavorable for improving the energy density of battery 100, simultaneously, can also increase and connect the turn-ups 10 and keep the ability of self shape.

In some embodiments, referring to fig. 13, the height H of the attachment cuff 10 ranges from: h is more than or equal to 1mm and less than or equal to 6mm. For example, the height H of the connecting flange 10 may be 1mm, 2mm, 3mm, 4mm, 5mm or 6mm, which is not limited in the present utility model, and the height H of the connecting flange 10 may be reasonably selected in the above range according to practical needs. In this way, it is possible to avoid that the height H of the connection flange 10 is too small, for example, less than 1mm, to form an effective fit with the fitting structure on the electronic device, and in addition, it is possible to avoid that the thickness of the battery 100 is affected when the height H of the connection flange 10 is too large, for example, greater than 6mm.

In some embodiments, in combination with fig. 1, 4, 6 and 13, the connection structure 101 may be formed as a connection hole, and the connection structure 101 penetrates the connection flange 10 along the thickness direction of the connection flange 10, so that the connection structure 101 is relatively simple and easy to process. At this time, the assembly structure of the electronic device may be formed as a plug post that is in plug-in fit with the connection hole, a buckle that is in snap-fit with the connection hole, or the like. Of course, the present utility model is not limited thereto, and the connection structure 101 may be formed as a card slot or other structures.

In some embodiments, referring to fig. 15-17, the attachment cuff 10 is parallel to the reference plane, in other words, the attachment cuff 10 of this embodiment is in a straight configuration. The connection structure 101 is formed as a plurality of clamping grooves, which are arranged at intervals along the length direction of the connection flange 10. For example, as shown in fig. 14, the connection flanges 10 may be located on both sides of the housing 1 in the width direction, and in this case, a plurality of clamping grooves on each connection flange 10 are arranged at intervals along the length direction of the connection flange 10 (i.e., the length direction of the housing 1); or as shown in fig. 15 and 16, the connection flanges 10 may be located on both sides of the housing 1 in the longitudinal direction, in which case a plurality of catching grooves on each connection flange 10 are arranged at intervals along the longitudinal direction of the connection flange 10 (i.e., the width direction of the housing 1). Of course, the connection structure 101 may be formed only on the connection flange 10 on one of the opposite sides of the housing 1, or the connection structure 101 may be formed on the connection flange 10 on the opposite sides of the housing 1, and the clamping groove may be clamped with the assembly structure of the electronic device. Therefore, the structure of the housing 1 of the embodiment is simpler, and the bending process can be omitted, thereby being beneficial to improving the production efficiency.

In some embodiments, the casing 1 is a metal piece, for example, the casing 1 may be a steel casing, so that the casing 1 has a certain structural strength, and can better protect an internal battery cell, and meanwhile, the structural strength of the folded connection flange 10 is high enough, so that deformation is not easy to occur.

In some embodiments, referring to fig. 1 to 7, the number of the first connection sides 112 may be two, and the two first connection sides 112 are respectively disposed on opposite sides of the receiving portion 111 along the width direction thereof, and accordingly, the number of the second connection sides 121 is two, and the two second connection sides 121 are in one-to-one correspondence with and connected to the first connection sides 112, so that when the battery 100 is mounted to an electronic device, both sides of the battery 100 along the width direction can be connected to the mounting structure of the electronic device, and the mounting stability of the battery 100 can be improved.
