It can be understood that the flexible belt 31 has the characteristics of stretching, compression, bending and torsion under external force without breaking, so that the supporting part 32 at the first end of the flexible belt 31 can move around the second end of the flexible belt 31 under external force, improving the use flexibility of the flexible support 3. In addition, the structure of the flexible support 3 is simple and has high reliability.

[0045] Please refer to Figure 6 The flexible belt 31 includes a first surface 31c and a second surface 31d opposite to the first surface 31c, and the supporting part 32 protrudes from the first surface 31c. It should be noted that the specific size of the supporting part 32 protruding from the first surface 31c is not limited.

[0046] Please refer to Figure 1 and Figure 5 The flexible support 3 has an unfolded state and a storage state. Please refer to Figures 1 to 4 In the storage state, the first surface 31c is attached to the outer surface of the housing 1, and the supporting part 32 is detachably connected with the housing 1; please refer to Figures 5 to 7In the unfolded state, the support part 32 is separated from the shell 1 to make the flexible band 31 move around the second end to unfold, and the support part 32, the first surface 31c of the flexible band 31 and the shell 1 are used to support the mobile terminal 4. It can be understood that when the user needs to use the mobile power supply, the user can convert the flexible support 3 to the unfolded state, the mobile terminal 4 can be placed on the flexible support 3, and the mobile terminal 4 is supported by the support part 32, the first surface 31c of the flexible band 31 and the shell 1, so that the mobile terminal 4 can maintain a certain inclination angle, meeting the needs of the user to free both hands to watch or use the mobile terminal 4.

[0047] When the user does not need to use the mobile power supply, the user can convert the flexible support 3 to the storage state, in which the first surface 31c of the flexible band 31 is attached to the outer surface of the shell 1, so that the overall size of the mobile power supply is compact, facilitating the user to carry and store it. In addition, the support part 32 can also be detachably connected with the shell 1, which can improve the stability of the first surface 31c of the flexible band 31 attached to the outer surface of the shell 1, and reduce the possibility of the first end of the flexible support 3 being separated from the outer surface of the shell 1.

[0048] The mobile power supply provided by the embodiment of the present application has a storage state and an unfolded state by setting the flexible support 3. In the unfolded state, the user can place the mobile terminal 4 on the flexible support 3, and support the mobile terminal 4 by the support part 32, the first surface 31c of the flexible band 31 and the shell 1, so that the mobile terminal 4 can maintain a certain inclination angle, meeting the needs of the user to free both hands to watch or use the mobile terminal 4.

[0049] In addition, in the unfolded state, the mobile terminal is supported by the support part 32, the first surface 31c of the flexible band 31 and the shell 1, etc., so that the mobile terminal 4 cannot be easily shaken, and the support is better, facilitating the user to watch or use the mobile terminal 4. At the same time, in the storage state, the support part 32 is detachably connected with the shell 1, so that the first end of the flexible band 31 cannot be easily separated from the outer surface of the shell 1 by external force, facilitating carrying, transportation and packaging.

[0050] Exemplarily, the flexible support 3 is of an integrated structure. In this way, not only the production efficiency of the flexible support 3 can be improved, but also the connection strength of the flexible band 31 and the support part 32 can be improved, thereby improving the use reliability of the flexible support 3.

[0051] Exemplarily, the flexible support 3 is of a split structure, for example, the support part 32 and the flexible band 31 are connected by plug-in cooperation. In this way, the user can replace the support part 32 or the flexible band 31 individually, thereby reducing the use cost of the flexible support 3.

[0052] It should be noted that the specific manner in which the second end of the flexible band 31 is connected to the housing 1 is not limited.

[0053] Exemplarily, the second end of the flexible band 31 is rotationally connected to the housing 1. In this way, the support portion 32 is facilitated to rotate around the second end, and the flexible support 3 is facilitated to switch from the storage state to the unfolded state.

[0054] Exemplarily, please refer to Figure 8 and Figure 9 , the flexible support 3 includes one or more hooks 31a arranged at the second end of the flexible band 31, and the housing 1 has one or more slots 1b, the hooks 31a being connected to the slots 1b. It can be understood that after the hooks 31a extend into the slots 1b, the slots 1b can restrict the movement of the hooks 31a to achieve the connection relationship between the second end of the flexible band 31 and the housing 1. In addition, the cooperation of the hooks 31a and the slots 1b can make the flexible band 31 and the housing 1 have better connection strength, so that the flexible band 31 is not easily separated from the housing 1 during use.

[0055] It should be noted that the specific size of the flexible band 31 along the length direction is not limited.

[0056] In some embodiments, please refer to Figures 1 to 3 , the size of the housing 1 along the first direction is smaller than the size of the housing 1 along the second direction, and the size of the housing 1 along the first direction is smaller than the size of the housing 1 along the third direction. It can be understood that the housing 1 is generally flat, so that the shape of the power bank is flat, which is convenient for users to carry at any time.

[0057] It should be noted that the first direction, the second direction, and the third direction are perpendicular to each other.

[0058] Exemplarily, please refer to Figure 3 , the second end of the flexible band 31 is located at one side of the housing 1 along the first direction, and the first end of the flexible band 31 can extend to the other side of the housing 1 along the first direction around the edge of the housing 1 along the second direction or the third direction.

[0059] Thus, on the one hand, in the storage state, the flexible support 3 can utilize the flexible band 31 to wrap from one side of the shell 1 along the first direction to the other side of the shell 1 along the first direction, so that the length of the flexible band 31 is as long as possible, and the flexible support 3 can support a mobile terminal 4 with a large size, such as a tablet computer, in the unfolded state; on the other hand, when the power bank is placed on a medium surface, the first direction of the shell 1 is perpendicular to the medium surface, and the second end of the flexible band 31 is located on the side of the shell 1 close to the medium surface, under the action of the gravity of the power bank, the second end of the flexible band 31 can be stably connected with the shell 1 under the interaction of the shell 1 and the medium surface, and the possibility of the second end of the flexible band 31 falling off the shell 1 during use can be reduced; on the third hand, when the power bank is placed on the medium surface, the first direction of the shell 1 is perpendicular to the medium surface, and the second end of the flexible band 31 is located on the side of the shell 1 close to the medium surface, after the supporting part 32 moves around the second end of the flexible band 31 in the unfolded state, the second surface 31d of the flexible band 31 is in contact with the medium surface, and the supporting part 32, the flexible band 31 and the shell 1 can support the mobile terminal 4.

[0060] Exemplarily, the clamping hook protrudes from the first surface 31c of the flexible band 31. It can be understood that the clamping hook and the supporting part 32 protrude from the same side of the surface, so that the clamping hook and the supporting part 32 are connected with the shell 1 at the same time.

[0061] In some embodiments, please refer to Figure 6 In the unfolded state, the flexible band 31 can be elongated by 5% to 30% in the length direction under the action of an external force, for example, by 5%, 6%, 7%, 8%, 9%, 10%, 12%, 15%, 17%, 20%, 25% or 30%, etc. It can be understood that in the unfolded state, the user applies a force to the first end of the flexible band 31 to elongate the flexible band 31 in the length direction, when the supporting part 32, the flexible band 31 and the shell 1 support the mobile terminal 4, the included angle (hereinafter referred to as included angle D) between the surface of the side of the mobile terminal 4 in contact with the shell 1 and the medium surface will decrease due to the elongation of the length of the flexible band 31, and the forces generated by the mobile terminal 4 in contact with the first surface 31c of the supporting part 32 and the flexible band 31 will limit the contraction of the flexible band 31, so that the included angle D can be kept stable when the mobile terminal 4 is placed on the flexible support 3, thus the user can adjust the included angle D of the mobile terminal 4 by stretching the flexible band 31 to an appropriate length, so as to facilitate the user to watch or operate the mobile terminal 4 at an appropriate angle, thereby improving the user experience.

[0062] It should be noted that the length direction refers to the direction from the supporting part 32 to the clamping hook 31a of the flexible band 31, for example, when the flexible band 31 is in the state shown in the figure, the direction indicated by the arrow in the figure. Figure 8

[0063] ​It should be noted that the specific structure of the flexible band 31 is not limited. For example, the flexible band 31 can be a TPU piece, a TPE piece, a TPR piece, or a silicone piece.

[0064] In some embodiments, referring to Figure 5 , the housing 1 is partially recessed inward and forms a recessed area 1a for accommodating the flexible band 31 in the storage state. It can be understood that, in the storage state, the recessed area 1a accommodating the flexible band 31 can reduce the possibility of the flexible band 31 protruding from the surface of the housing 1 as much as possible, on the one hand, it can improve the ornamental nature of the appearance of the mobile power supply; on the other hand, it can reduce the size of the mobile power supply as much as possible, so that the mobile power supply is compact, and it is convenient for users to carry at any time.

[0065] Exemplarily, referring to Figures 1 to 4 , in the storage state, the second surface 31d of the flexible band 31 is flush with the outer surface of the housing 1. In this way, in the storage state, the recessed area 1a accommodates the flexible band 31, the first surface 31c of the flexible band 31 is attached to the surface of the recessed area 1a, and the second surface 31d of the flexible band 31 is flush with the outer surface of the housing 1, which can make the appearance of the mobile power supply as flat as possible, and can improve the ornamental nature of the appearance of the mobile power supply.

[0066] In some embodiments, referring to Figure 2 , the first end of the flexible band 31 has a protruding structure 31b protruding from the second surface 31d. It can be understood that, in the storage state, the flexible band 31 is in the recessed area 1a, the first surface 31c is attached to the surface of the recessed area 1a, and the second surface 31d is located on the side of the flexible band 31 away from the recessed area 1a, so that the user can observe the protruding structure 31b on the appearance of the mobile power supply, which is convenient for the user to identify the first end of the flexible band 31, and is convenient for the user to convert the flexible support 3 to the unfolded state by making the supporting part 32 away from the housing 1, and improves the operation convenience of the user.

[0067] In some embodiments, referring to Figures 2 to 4 , in the storage state, the protruding structure 31b protrudes from the outer surface of the housing 1. In this way, it is convenient for the user to grab the protruding structure 31b, and by applying a force to the protruding structure 31b, the first end of the flexible band 31 is away from the contact with the housing 1, so that the user can make the supporting part 32 away from the housing 1, so that the flexible support 3 can be converted to the unfolded state, and improves the use convenience of the user.

[0068] In some embodiments, the surface of the recessed area 1a is provided with an information identification area (not shown in the figure) which includes at least one technical parameter of the power bank. It can be understood that the surface of the recessed area 1a can be fully utilized, and in the storage state, the flexible band 31 can shield the information identification area, so that the appearance of the power bank is simple, thereby improving the ornamental value of the appearance of the power bank.

[0069] It should be noted that the technical parameters of the power bank refer to information such as battery capacity, battery type, product type, charging protocol, maximum output power, output voltage, output current, and rated capacity.

[0070] It should be noted that the specific direction in which the support part 32 is detachably connected with the shell 1 is not limited.

It can be understood that in the storage state, the support part 32 is inserted into the locking groove 1c, on the one hand, the connection strength of the support part 32 and the shell 1 can be improved, so that the support part 32 is not easily separated from the shell 1, thereby the first end of the flexible band 31 is not easily separated from the outer surface of the shell 1 under external force, which is convenient for carrying, transporting and packaging; on the other hand, the locking groove 1c can protect the support part 32, thereby reducing the possibility of damage to the support part 32, thereby prolonging the service life of the support part 32.

[0072] It should be noted that the specific structure of the support part 32 is not limited; the specific material forming the support part 32 is not limited, for example, the support part 32 can be made of plastic material.

[0073] In some embodiments, referring to Figure 3 , Figure 4 and Figure 9The support portion 32 comprises a first side 32a facing the second end of the flexible band 31 and a second side 32b opposite to the first side 32a, and the second side 32b is provided with an elastic hook 32c which is detachably locked with the locking groove 1c. It can be understood that the locking of the elastic hook 32c with the locking groove 1c can make the connection of the support portion 32 with the shell 1 more stable, and can reduce the possibility that the support portion 32 is easily separated from the shell 1 by external force, facilitating carrying, transportation and packaging. In addition, the elastic hook 32c is located on the side away from the second end of the flexible band 31, and when the user applies a force around the second end to the first end of the flexible band 31 to convert the flexible support 3 to the unfolded state, the elastic hook 32c can move towards the second end under the action of the force, so that the elastic hook 32c is separated from the locking groove 1c, thereby separating the support portion 32 from the shell 1, and improving the reliability of the flexible support 3 in switching from the storage state to the unfolded state.

[0074] In some embodiments, please refer to Figure 3 , Figure 4 and Figure 8 The second side 32b is provided with an anti-slip structure 32d. It can be understood that the anti-slip structure 32d can increase the friction coefficient of the second side 32b, thereby increasing the friction force between the support portion 32 and the mobile terminal 4, so that the mobile terminal 4 cannot easily shake, and the support is better, facilitating the user to watch or use the mobile terminal 4.
