Detailed implementation manners

[0028] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. Based on the embodiments in the implementation manners, it is intended to explain the present invention and should not be construed as a limitation to the present invention.

[0029] As used in this specification, the phrase "in one embodiment" or "example" or "instance" means that a particular feature, structure, or characteristic described in connection with the embodiment itself can be included in at least one embodiment of the present patent disclosure. The appearances of the phrase "in one embodiment" at various positions in the specification do not necessarily refer to the same embodiment.

[0030] This embodiment provides a mobile power supply with a built-in charging cable. As Figure 1 and Figure 2 shown, it includes a mobile power supply main body 10 and at least one charging cable 20. An installation cavity 10c is formed in the mobile power supply main body 10. At least one first installation hole 10a and at least one second installation hole 10b are formed on the installation surface 12 of the mobile power supply main body 10, and each first installation hole 10a and each second installation hole 10b communicate with the installation cavity 10c. The first installation holes 10a and the second installation holes 10b correspond to the charging cables 20 one by one. The mobile power supply further includes a support member 30, and the support member 30 is arranged in the installation cavity 10c. The charging cable 20 has an input end 21 and an output end 22. Each input end 21 is arranged in the corresponding first installation hole 10a and is electrically connected to the mobile power supply main body 10. Each output end 22 can be respectively inserted into the corresponding second installation hole 10b and is clamped with the support member 30.

[0031] By providing a charging cable 20 on the power bank main body 10, users do not need to additionally configure the charging cable 20, improving the convenience of use. The input end 21 is fixed in the first mounting hole 10a, ensuring charging efficiency and stability; while the output end 22 adopts a plug-and-play design and cooperates with the second mounting hole 10b, facilitating the storage and removal of the charging cable 20. After the output end 22 is inserted into the second mounting hole 10b, the charging cable 20 can form a loop by itself. On the one hand, it is convenient for users to hold the power bank by hand or hang the power bank on a backpack, which is easy to carry and convenient for users to use at any time; on the other hand, it avoids unnecessary bending of the charging cable 20 during frequent use, effectively reducing fatigue damage near the input end 21 and improving the service life of the charging cable 20 and the power bank.

[0032] Through the snap-fit cooperation between the support member 30 and the output end 22, the output end 22 can be fixed in the second mounting hole 10b to complete the storage of the charging cable 20. Moreover, by independently providing the support member 30 for fixing the output end 22, there is no need to perform complex mold opening design on the housing of the power bank main body 10, reducing the production cost. In this embodiment, there is no special limitation on the fixing method of the support member 30 and the power bank main body 10. For example, the support member 30 can be fixed to the inner wall of the installation cavity 10c formed in the power bank main body 10 by screws.

[0033] It can be understood that generally the shape of the power bank is a cuboid or near-cuboid. For the aesthetic appearance of the product and the convenience of storing the power bank, the installation surface 12 is the surface formed by enclosing the shortest side length and the second shortest side length of the power bank, or the surface formed by enclosing the shortest side length and the longest side length of the power bank.

[0034] In the present utility model, there is no special limitation on the relative positions of the first mounting hole 10a and the second mounting hole 10b. For improving the aesthetic appearance and the convenience of carrying the power bank, the first mounting hole 10a and the second mounting hole 10b are spaced apart along the thickness direction of the power bank main body 10 on the installation surface 12, and the thickness direction of the power bank main body 10 is consistent with the extending direction of the shortest side length of the power bank main body 10.

[0035] Optionally, as Figure 3 and Figure 4 shown, the support member 30 includes a support main body and at least one elastic protrusion 31. The support main body is formed with a receiving cavity 30a, and each elastic protrusion 31 is provided on the inner wall of the receiving cavity 30a.

[0036] A card slot 22a is formed on the side wall of the output end 22. When the output end 22 is inserted into the corresponding second mounting hole 10b, the elastic protrusion 31 can be inserted into the card slot 22a.

[0037] By setting the elastic protrusion 31 and the card slot 22a, the output end 22 can be relatively fixed with the second mounting hole 10b after being inserted into the second mounting hole 10b. It should be noted that, since the elastic protrusion 31 has a certain elasticity, when the charging cable 20 is pulled out from the second mounting hole 10b, the elastic protrusion 31 can be deformed so that the elastic protrusion 31 is moved out of the card slot 22a, thereby releasing the limiting effect on the output end 22.

[0038] In an alternative embodiment, Figure 4 and Figure 5 As shown, the elastic protrusion 31 has a first guide surface 312 and a second guide surface 311, and the angles formed by the first guide surface 312 and the second guide surface 311 with the first direction are both less than 90°, so that when the output end 22 is extended into the accommodating cavity 30a or pulled out from the accommodating cavity 30a, the elastic protrusion 31 can be squeezed by the output end 22 and shrink along the second direction in a direction away from the output end 22. The first direction is consistent with the opening direction of the second mounting hole 10b, and the second direction is consistent with the thickness direction of the mobile power supply body 10.

[0039] During the process of plugging and unplugging the output terminal 22, if the surface of the elastic protrusion 31 that limits the movement of the charging cable 20 is perpendicular to the first direction, where the first direction is consistent with the opening direction of the second mounting hole 10b and the plugging and unplugging direction of the output terminal 22, then the storage and removal of the charging cable 20 is not only laborious, but also easily causes damage to the support member 30 and the output terminal 22.

[0040] In order to reduce the force required for plugging and unplugging the output terminal 22, the elastic protrusion 31 in this embodiment is formed with a first guide surface 312 and a second guide surface 311, and the angles formed by the first guide surface 312 and the second guide surface 311 with the first direction are both less than 90°, so that when the output terminal 22 is inserted into the second mounting hole 10b, the input terminal 21 abuts against the first guide surface 312 and continuously squeezes the elastic protrusion 31, causing the elastic protrusion 31 to deform, until the elastic protrusion 31 is opposite to the slot 22a, and the elastic protrusion 31 recovers its deformation and is inserted into the slot 22a. When the input terminal 21 is pulled out of the second mounting hole 10b, the opening edge of the slot 22a abuts against the second guide surface 311 and continuously squeezes the elastic protrusion 31, causing the elastic protrusion 31 to deform, and after the input terminal 21 is pulled out of the second mounting hole 10b, the elastic protrusion 31 recovers its deformation.

[0041] Optionally, the side wall of the output end 22 formed with the slot 22 a can fit with the inner wall of the accommodating cavity 30 a.

[0042] When the receiving cavity 30a is inserted into the input end 21, the side wall of the output end 22 formed with the card slot 22a fits against the inner wall of the receiving cavity 30a, restricting the movement of the output end 22 in the second direction and improving the connection stability between the charging cable 20 and the mobile power supply main body 10 during storage.

[0043] In an alternative embodiment, the mobile power supply includes a main board disposed in the installation cavity 10c, and the input end 21 is electrically connected to the main board. A plurality of limiting ridges 11 are formed on the inner wall of the installation cavity 10c, and a plurality of limiting grooves 21a are formed on the side wall of the input end 21. The limiting ridges 11 are inserted into the limiting grooves 21a.

[0044] Through the cooperation of the limiting ridges 11 and the limiting grooves 21a, the input end 21 is fixed on the mobile power supply main body 10. In the production and processing process, the direct fixing method requires more tools and installation steps, such as drilling, tapping, bolt tightening, etc., increasing the complexity and cost of installation. However, by using the snap connection method to fix the input end 21, the installation efficiency is improved and the production cost is reduced.

[0045] Optionally, the charging cable 20 includes a charging cable main body 23, and the charging cable main body 23 is connected between the input end 21 and the output end 22. The cross-section of the charging cable 20 body is rectangular.

[0046] When the input end 21 is inserted into the second installation hole 10b, the charging cable 20 can form a loop. By designing the charging cable 20 body to have a rectangular cross-section, when carrying the mobile power supply by hand, the contact area between the charging cable 20 and the hand is increased, preventing hand strangulation and improving the user experience.

[0047] In an alternative embodiment, the charging cable 20 further includes a flexible connection sleeve, and the flexible connection sleeve is sleeved on the charging cable 20 body and is connected to the output end 22.

[0048] By providing the flexible connection sleeve, it is possible to prevent local damage and breakage of the charging cable main body 23 caused by frequent bending of the output end 22 of the charging cable 20 when connected to the device to be charged.

[0049] Optionally, as Figure 1 shown, at least one of the first side wall 13 and the second side wall 14 of the mobile power supply main body 10 is provided with a charging port 10d for electrically connecting to the input end 21 of an external charging cable. The first side wall 13 and the second side wall 14 are opposite, and both the first side wall 13 and the second side wall 14 are adjacent to the installation surface 12.

[0050] By providing the charging port 10d, the interface type of the output end 22 of the charging cable 20 is not limited, and external charging cables with different interface types can be electrically connected to the charging port 10d, and the devices with the corresponding interface types can be charged through the external charging cable, thereby improving the versatility of the mobile power supply. It is understandable that the charging port 10d and the built-in charging cable 20 can charge different devices to be charged at the same time.

[0051] In the present invention, there is no special limitation on the type of the charging port 10d. For example, the charging port 10d is any one of a USB port, a Lightning port, and a Type-C port.

[0052] Alternatively, if Figure 1 As shown, the mobile power supply further includes a plurality of power indicator lights 40 , and the plurality of power indicator lights 40 are disposed on the mounting surface 12 .

[0053] By setting the power indicator 40, the number of lights on different power indicator lights 40 represents different remaining power, which is convenient for reminding users to charge in time. Preferably, the power indicator light 40 has multiple display states, including a breathing state and a constant light state. Usually, when charging the mobile power supply, when the power indicator light 40 is in the breathing state, it means that the mobile power supply is charging; when the power indicator light 40 is in the constant light state, it means that the mobile power supply is fully charged.

[0054] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention shall be included in the scope of the claims.
