Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments described in this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] In this embodiment of the invention, the use of terms such as "first" and "second" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0032] Reference Figure 1 , Figure 2 and Figure 3As shown in the figure, a portable power bank 1 provided by this utility model embodiment includes: a first connecting line 10, a second connecting line 20, and a power supply body 70. One end of the first connecting line 10 is connected to the power supply body 70, and the other end of the first connecting line 10 is provided with a first electrical connector 103. One end of the second connecting line 20 is connected to the power supply body 70, and the other end of the second connecting line 20 is provided with a second electrical connector 203. The power supply body 70 is provided with a first storage slot 401 and a second storage slot 402. The first electrical connector 103 is detachably connected to the first storage slot 401, and the second electrical connector 203 is detachably connected to the second storage slot 402. When the first electrical connector 103 and the second electrical connector 203 are respectively connected to the first storage slot 401 and the second storage slot 402, the first connecting line 10 and the second connecting line 20, together with the power supply body 70, form a first handheld area 60 and a second handheld area 61, respectively, and the first handheld area 60 and the second handheld area 61 at least partially overlap.

[0033] The power bank 1, also known as a portable charger, is a portable charger that integrates power supply and charging functions. It primarily provides temporary power support for mobile devices such as smartphones, tablets, and digital cameras, allowing them to continue operating normally when their battery is low. The power bank 1 has various designs, typically rectangular or square; this embodiment uses a rectangular design. The first connecting cable 10 and the second connecting cable 20 are the charging cables. Exemplarily, the first electrical connector 103 and the second electrical connector 203 can be any combination of one or more of Type-C, Lightning, and Micro USB, with various connector types available to suit different types of mobile terminal devices.

[0034] The handheld area is formed by the connecting cable and the power supply body 70, allowing the user to carry the power bank 1 by hand. The first handheld area 60 and the second handheld area 61 partially overlap and are independent of each other, allowing either handheld area to be used individually or simultaneously. For example, when the user is using the first connecting cable 10 to charge a mobile device, the second handheld area 61 formed by the second connecting cable 20 can be held by the user, enabling the user to hang or carry the power bank 1.

[0035] The power bank 1 has two connecting cables to meet the charging needs of multiple mobile devices. Both the first connecting cable 10 and the second connecting cable 20 have dual functions of charging and handheld use. When using the charging function of one connecting cable, the other connecting cable can provide the function of hanging or handheld carrying, meeting the charging needs in various scenarios.

[0036] Reference Figure 1 , Figure 2 and Figure 3As shown, the first connecting line 10 includes a first end 101, and the second connecting line 20 includes a third end 201. The first end 101 and the third end 201 are connected to the power supply body 70. The third end 201, the first end 101, the second storage slot 402, and the first storage slot 401 are arranged sequentially along the circumference of the power supply body 70. Specifically, the power supply body 70 includes a housing 40 and a battery cell assembly 30. The housing 40 is fitted over the battery cell assembly 30. The first end 101 of the first connecting line 10 and the third end 201 of the second connecting line 20 are housed within the housing 40 and electrically connected to the battery cell assembly 30. The first end 101 and the third end 201 can be fixed at the same location or spaced apart along the extension direction of the sidewalls near both ends. The second end 102 of the first connecting line 10 and the fourth end 202 of the second connecting line 20 provide electrical input to the power supply 1 and power output to the mobile device.

[0037] The third end 201, the first end 101, the second storage slot 402, and the first storage slot 401 are sequentially arranged on the housing 40. The second connecting line 20 is stored in the second storage slot 402 to form a first handheld area 60. The second end 102 of the first connecting line 10 passes through part of the internal space of the housing 40, emerges from the adjacent side wall of the side wall where the first end 101 is located, and is stored in the first storage slot 401. The portion of the first connecting line 10 exposed on one side of the housing 40 where the first end 101 is located forms the second handheld area 61. The second handheld area 61 is fitted over the first handheld area 60 and at least partially overlaps it. The first connecting line 10 partially passes through the interior of the housing 40 to achieve a retractable function, further optimizing the spatial layout of the power bank 1 and making the size of the housing 40 meet the user's convenience needs. Furthermore, when the first connecting line 10 and the second connecting line 20 are respectively stored in the first storage slot 401 and the second storage slot 402, the appearance is more concise and aesthetically pleasing.

[0038] Reference Figure 1 and Figure 3 As shown, in this embodiment of the present invention, the power supply body 70 is provided with a wire passage groove 50. The wire passage groove 50 is located inside the power supply body 70 and is spaced apart from the second storage groove 402. The wire passage groove 50 is located on the side of the first storage groove 401 near the first end 101 and is connected to the first storage groove 401. The first connecting wire 10 passes through the wire passage groove 50. The first connecting wire 10 has a pull-out structure. When using the first connecting wire 10, if the user wants to extend its use, he / she can pull the second end 102. At this time, the part of the first connecting wire 10 that surrounds the first handheld area 60 is pulled through the wire passage groove 50, so that the second end 102 is exposed in the wire passage groove 50 and the first connecting wire 10 is extended. By setting the wire passage groove 50 inside the housing 40, and storing the second end 102 of the first connecting wire 10 in the first storage groove 401 through the wire passage groove 50, the pull-out structure of the first connecting wire 10 is realized, and the size of the outer housing 40 is reduced.

[0039] In the embodiments of this utility model, reference is made to Figure 2 and Figure 3 As shown, the power supply body 70 includes a first sidewall 406 and a second sidewall 407 arranged opposite to each other along a first direction, a second storage groove 402 located on the first sidewall 406, and a wire channel 50 and the second storage groove 402 spaced apart along the first direction.

[0040] The wire guide 50 is positioned inside the housing 40 near the side wall of the second storage slot 402, and occupies only a portion of the internal space of the housing 40, isolating the storage path of the first connecting wire 10 and the storage path of the second connecting wire 20. The wire guide 50 is connected to the first storage slot 401 and spaced apart from the second storage slot 402, making efficient use of the internal space of the housing 40, reducing the thickness of the housing 40, resulting in a more compact overall structure and avoiding wasted space.

[0041] Reference Figure 4 As shown, in an embodiment of this utility model, the first storage slot 401 is at least partially disposed on the first side wall 406. The first storage slot 401 and the second storage slot 402 are both disposed on the same side wall, and the two are independent of each other and do not entangle with each other, avoiding additional occupation of the space of the opposite side wall, effectively reducing the overall space occupation, thereby realizing the reduction of the size of the shell 40, making it easier to carry.

[0042] Reference Figure 3 and Figure 6 As shown, in an embodiment of this utility model, the first storage groove 401 includes a limiting groove 4011, which is connected to the wire passage groove 50 and located on the side of the wire passage groove 50 away from the first end 101. The first connecting line 10 is provided with a stop block 104, and a limiting step 40110 is provided in the limiting groove 4011. When the stop block 104 is located in the limiting groove 4011, the stop block 104 abuts against the limiting step 40110.

[0043] The limiting groove 4011 is located inside the housing 40 and communicates with the wire passage groove 50. The limiting groove 4011 is used to place the stop block 104, and the stop block 104 is fixed on the first connecting line 10. The limiting step 40110 is located at the connection between the limiting groove 4011 and the wire passage groove 50. When the stop block 104 abuts against the limiting step 40110, the first handheld area 60 can be used. The first connecting line 10 passes through the wire passage groove 50 and the limiting groove 4011 in sequence and is fixed in the first storage groove 401. When the handheld function of the first connecting line 10 is used to carry the mobile device, the portion of the first connecting line 10 forming the first handheld area 60 is subjected to tension. The tension is transmitted from the first end 101 of the first connecting line 10 to the second end 102. The stop block 104 is provided to prevent the portion of the first connecting line 10 near the second end 102 from passing through the wire passage groove 50. Secondly, when the stop block 104 abuts against the connection between the limiting groove 4011 and the wire groove 50, the first electrical connector 103 can be accurately aligned and fixed in the first storage part 4010.

[0044] Reference Figure 6 As shown, in this embodiment of the present invention, the groove width D3 of the limiting groove 4011 is greater than the groove width D4 of the wire passage groove 50. The stop block 104 is placed in the limiting groove 4011, and the width of the stop block 104 is also greater than the groove width D4 of the wire passage groove 50. This ensures that when the first connecting wire 10 is subjected to tension, the stop block 104 abuts against the limiting step 40110 and cannot move into the wire passage groove 50, thereby ensuring that the first connecting wire 10 is in a stable state when the first handheld area 60 is used.

[0045] Reference Figure 3 As shown, in this embodiment of the present invention, a fifth magnetic element 1041 is provided inside the stop block 104, and a sixth magnetic element 405 is provided inside the power supply body 70. The stop block 104 is magnetically fixed inside the limiting groove 4011. Specifically, the fifth magnetic element 1041 is located on the side of the stop block 104 near the inside of the housing 40, and the sixth magnetic element 405 is located on the side of the housing 40 near the limiting groove 4011.

[0046] A magnetic suction element is provided at the connection point between the stop block 104 and the limiting groove 4011 near the wire passage groove 50 to further assist in fixing the stop block 104 in the limiting groove 4011, so that the first electrical connector 103 can be quickly aligned and fixed in the first storage part 4010. Secondly, when using the handheld function of the first connecting cable 10, the magnetic suction element further strengthens the fixation of the stop block 104, preventing the first connecting cable 10 from loosening due to the pulling force generated by the handheld action, and ensuring that the first connecting cable 10 remains stable under force.

[0047] Reference Figure 3As shown in the embodiment of this utility model, the first electrical connector 103 is provided with a first magnetic element 1031, and the power supply body 70 is provided with a second magnetic element 403. The first electrical connector 103 is magnetically fixed in the first storage groove 401. The second electrical connector 203 is provided with a third magnetic element 2031, and the power supply body 70 is provided with a fourth magnetic element 404. The second electrical connector 203 is magnetically fixed in the second storage groove 402.

[0048] Specifically, the first magnetic chuck 1031 is located on the side of the first electrical connector 103 near the interior of the housing 40, the second magnetic chuck 403 is located inside the housing 40 near the first storage slot 401, the third magnetic chuck 2031 is located on the side of the second electrical connector 203 near the first storage slot 401, and the fourth magnetic chuck 404 is located inside the housing 40 near the second storage slot 402. By providing magnetic chucks in the storage section and in the first electrical connector 103 and the second electrical connector 203, when the user wants to store the first electrical connector 103 or the second electrical connector 203, they only need to place the first electrical connector 103 or the second electrical connector 203 in the storage section. The magnetic force between the magnetic chuck in the storage section and the magnetic chuck in the first electrical connector 103 or the second electrical connector 203 causes the first electrical connector 103 or the second electrical connector 203 to automatically store itself into the storage space, which is highly convenient. Secondly, the magnetic attachment further secures the power bank 1, preventing the first electrical connector 103 or the second electrical connector 203 from easily detaching from the storage compartment and swinging or colliding freely outside the housing 40 when the power bank 1 is subjected to external forces such as shaking or bumping during carrying.

[0049] Reference Figure 3 and Figure 4 As shown, in an embodiment of this utility model, the first storage slot 401 includes a wire placement slot 4012, which is connected to the limiting slot 4011 and is located on the side of the limiting slot 4011 away from the wire passage slot 50. The limiting slot 4011 is inclinedly disposed on the power supply body 70 based on the wire placement slot 4012.

[0050] Specifically, the cable tray 4012 is used to place the cable body. The limiting groove 4011, based on the inclined setting of the cable tray 4012 and inside the housing 40, significantly reduces the probability of damage or scratches to the outer sheath of the first connecting cable 10 when it is pulled out, due to the excessively perpendicular angle between the limiting groove 4011 and the cable tray 50. This effectively extends the service life of the first connecting cable 10.

[0051] Reference Figure 3 and Figure 6 As shown, in this embodiment of the present invention, the inner wall of the limiting groove 4011 and the inner wall of the wire placement groove 4012 form an angle β. The inner wall of the limiting groove 4011 forms a guide slope 4013. The guide slope 4013 improves the smoothness of pulling the first connecting line 10 and enhances the ease of operation.

[0052] Reference Figure 6 As shown, specifically, the included angle β is an obtuse angle, ranging from 130° to 160°. When a pulling force is applied to the first connecting line 10, the obtuse angle within the range of 130° to 160° effectively decomposes the pulling force into components along the inclined plane and perpendicular to the inclined plane. The larger obtuse angle makes the component force perpendicular to the inclined plane relatively small, reducing the pressure of the first connecting line 10 on the inclined plane, thereby reducing friction; at the same time, the component force along the inclined plane is relatively large, which is more conducive to the sliding of the first connecting line 10 on the inclined plane, further improving the smoothness of the pulling.

[0053] In an embodiment of this utility model, the first connecting line 10 includes a first end 101, and the second connecting line 20 includes a third end 201. The first end 101 and the third end 201 are connected to the power supply body 70. The third end 201, the first end 101, the first storage slot 401, and the second storage slot 402 are arranged sequentially along the circumference of the power supply body 70. When the first electrical connector 103 and the second electrical connector 203 are connected to the first storage slot 401 and the second storage slot 402 respectively, the portion of the first connecting line 10 forming the first handheld area 60 is exposed outside the power supply body 70, and the portion of the second connecting line 20 forming the second handheld area 61 is exposed outside the power supply body 70 and at least partially overlaps with the first storage slot 401 along the circumference of the power supply body 70.

[0054] Specifically, in this embodiment, both the first storage slot 401 and the second storage slot 402 are disposed on the first sidewall 406, and the length of the second connecting line 20 is greater than the length of the first connecting line 10. The first connecting line 10 does not pass through the cable groove 50, and its wires are exposed outside the power supply body 70. This connection method forms a first handheld area 60 and a second handheld area 61, which allows the user to charge the phone using one connecting line while simultaneously using the other connecting line for handheld operation.

[0055] Reference Figure 3 and Figure 7 As shown, in an embodiment of this utility model, the length of the first connecting line 10 is greater than the length of the second connecting line 20. The greater length of the first connecting line 10 effectively increases its operability to adapt to various application requirements.

[0056] Reference Figure 2 and Figure 3As shown, in an embodiment of this utility model, a first storage section 4010 is provided in the first storage slot 401, and a first electrical connector 103 is snapped into the first storage section 4010. A second storage section 4020 is provided in the second storage slot 402, and a second electrical connector 203 is snapped into the second storage section 4020. The first storage section 4010 and the second storage section 4020 are located on the same side wall of the power supply body 70 or on adjacent side walls, respectively.

[0057] The first storage section 4010 and the second storage section 4020 can fix the first electrical connector 103 and the second electrical connector 203. When storing the first connecting cable 10 and the second connecting cable 20, the first electrical connector 103 and the second electrical connector 203 are simply snapped into the first storage section 4010 and the second storage section 4020 to complete the storage. Furthermore, the design of the first storage section 4010 and the second storage section 4020 achieves concealed storage, making the appearance neater when stored. (Refer to...) Figure 4 As shown, when the first storage part 4010 and the second storage part 4020 are located on adjacent side walls, the spatial dimensions of the housing 40 are effectively reduced, avoiding the waste of space in the housing 40 caused by the first storage part 4010 and the second storage part 4020 being located on opposite side walls.

[0058] Reference Figure 4 , Figure 5 and Figure 8 As shown, both the first storage section 4010 and the second storage section 4020 are provided with a first latching portion 40101 and a second latching portion 40102. The housing 40 includes a first sidewall 406 and a third sidewall 408 disposed adjacent to each other. The first latching portion 40101 and the second latching portion 40102 are disposed on the sidewall of the first storage section 4010, and the first latching portion 40101 is connected to the second latching portion 40102, and are arranged sequentially in a direction gradually approaching the first sidewall 406. The first latching portion 40101 and the second latching portion 40102 are disposed on the sidewall of the second storage section 4020, and the first latching portion 40101 is connected to the second latching portion 40102, and are arranged sequentially in a direction gradually approaching the third sidewall 408. The groove width D1 formed by the first snap-fit ​​portion 40101 within the first storage portion 4010 and the second storage portion 4020 is greater than the groove width D2 formed by the second snap-fit ​​portion 40102 within the first storage portion 4010 and the second storage portion 4020.
