Description

Technical Field

[0001] The utility model relates to the technical field of mobile power supplies, and particularly relates to a rotary mobile power supply. Background Art

[0002] A mobile power supply, commonly known as a power bank, is a portable temporary power source, often used in outdoor places. Most traditional mobile power supplies are flat cuboids, and charging ports and discharging ports are arranged on their sides. When charging electronic products (such as mobile phones, tablets, etc.), users can connect the discharging port to the charging port of the electronic product through a charging cable. When charging the mobile power supply, the charging port is connected to an adapter through a charging cable and then connected to the power grid for power replenishment. The disadvantages of this traditional design are as follows:

[0003] 1. As the capacitance of the mobile power supply increases, the number of battery cells installed inside it becomes more and more, and the overall space occupied area is larger. It is not only inconvenient to hold, but also not easy to put into the storage bag for daily travel, resulting in inconvenient carrying;

[0004] 2. Both the charging port and the discharging port are in an exposed state, which is easy to accumulate dust and rust, resulting in poor electrical contact. Content of the Utility Model

[0005] Based on this, the utility model provides a rotary mobile power supply, which adopts a cylindrical and rotary structure to compress the overall space occupied area of the device. It is not only convenient to hold, but also easy to put into the storage bag for daily travel, improving the convenience of carrying. At the same time, when charging or discharging is not required, the charging port and the discharging port can be hidden to reduce the probability of dust accumulation and rust, and reduce the risk of poor electrical contact.

[0006] A rotary mobile power supply includes:

[0007] A charging base; the charging base is disc-shaped; one side of the charging base is provided with a first electrical slot and a plurality of first limiting holes circumferentially distributed around the first electrical slot; the charging base is also provided with a charging port;

[0008] A discharging base parallel to the charging base; the discharging base is disc-shaped; the side of the discharging base facing the charging base is provided with a second electrical slot and a plurality of second limiting holes circumferentially distributed around the second electrical slot; the discharging base is also provided with a discharging port;

[0009] A circuit board located between the charging base and the discharging base; one end of the circuit board is inserted into the first electrical slot, and the other end of the circuit board is inserted into the second electrical slot;

[0010] A battery pack located between the charging base and the discharging base; the battery pack includes: a plurality of cylindrical battery cells; each battery cell is plugged in between the first limiting hole and the second limiting hole in a one-to-one correspondence;

[0011] The outer shell is sleeved on the outer circumference of the battery pack; the outer shell is cylindrical with two ends open; the circuit board and the battery pack are both located in the inner cavity of the outer shell; the charging base and the discharging base both extend outside the end of the outer shell;

[0012] A charging rotating cover is sleeved on the charging base; the charging rotating cover and the charging base are relatively rotatable; the charging rotating cover is provided with a charging avoidance hole corresponding to the charging port; and

[0013] A discharge rotating cover is sleeved on the discharge base; the discharge rotating cover and the discharge base are relatively rotatable; the discharge rotating cover is provided with a discharge avoidance hole corresponding to the discharge port.

[0014] The above-mentioned rotary mobile power supply, the charging base, the battery pack, the circuit board, and the discharge base constitute a cylindrically distributed combined structure, which is then covered and protected by the shell, the charging rotary cover, and the discharge rotary cover. When the battery pack needs to be charged, by rotating the charging rotary cover, the charging port is opposite to the charging avoidance hole, so that the charging port can be exposed. On the contrary, it is only necessary to misalign the charging avoidance hole with the charging port, so that the charging port can be hidden, which plays a protective role. Similarly, when the electronic product needs to be charged, by rotating the discharge rotary cover, the discharge port is opposite to the discharge avoidance hole, so that the discharge port can be exposed. On the contrary, it is only necessary to misalign the discharge avoidance hole with the discharge port, so that the discharge port can be hidden, which plays a protective role. Through the above design, a cylindrical and rotary structure is adopted to compress the space occupied by the entire device, which is not only convenient for handholding, but also convenient for putting into a storage bag for daily travel, improving the convenience of carrying. At the same time, when it is not necessary to charge or discharge, the charging port and the discharge port can be hidden to reduce the probability of dust accumulation and rust, and reduce the risk of poor electrical contact.

[0015] In one embodiment, the charging port is located on the periphery of the charging base.

[0016] In one embodiment, the charging port is located on a side of the charging base away from the first limiting hole.

[0052] Below, in combination with Figures 1 to 12 , the above-mentioned rotary mobile power supply 100 will be further described.

[0053] As Figure 5 and Figure 6 shown, the charging base 10 is disc-shaped. One surface of the charging base 10 is provided with a first electrical slot 11 and a plurality of first limiting holes 12 circumferentially distributed around the first electrical slot 11. The charging base is also provided with a charging port 13. In this embodiment, the number of the first limiting holes 12 is four and they are distributed at 90° intervals.

[0054] like Figure 7 and Figure 8 As shown, the discharge base 20 is disc-shaped. A second electrical slot 21 and a plurality of second limiting holes 22 distributed circumferentially around the second electrical slot 21 are provided on the side of the discharge base 20 facing the charging base 10. The discharge base is also provided with a discharge port 23. In this embodiment, the number of the second limiting holes 22 is four and they are distributed at 90° intervals.

[0055] Combination Figure 3 and Figure 4 As shown, one end of the circuit board 30 is plugged into the first electrical slot 11 , and the other end of the circuit board 30 is plugged into the second electrical slot 21 .

[0056] Combination Figure 3 and Figure 4 As shown, the battery pack 40 includes: a plurality of cylindrical battery cells 41. Each battery cell 41 is inserted between the first limiting hole 12 and the second limiting hole 22 in a one-to-one correspondence. In this embodiment, the number of battery cells 41 is four, and the end of each battery cell 41 is inserted into the first limiting hole 12 and the second limiting hole 22 in a one-to-one correspondence.

[0057] like Figure 4 As shown, the housing 50 is cylindrical with two ends open. The circuit board 30 and the battery pack 40 are both located in the inner cavity of the housing 50. The charging base 10 and the discharging base 20 both extend outside the ends of the housing 50. Based on safety considerations, in this embodiment, the housing 50 can be an insulating shell made of organic glass. Furthermore, in other embodiments, the inner side of the housing 50 can also be provided with a buffer rubber sleeve, such as a silicone sleeve, to play a role in buffering and shock absorption.

[0058] like Figure 9 and Figure 10 As shown, the charging rotating cover 60 and the charging base 10 are relatively rotatable. The charging rotating cover 60 is provided with a charging avoidance hole 61 corresponding to the charging port 13.

[0059] In this solution, the specific position of the charging avoidance hole 61 corresponds to the specific position of the charging port 13. In this embodiment, the charging port 13 is specifically arranged at two locations, one is the peripheral side of the charging base 10, and the other is the end surface of the charging base 10, and one or both of them can be selected.

[0060] For example, combined with Figure 5 and Figure 6 As shown, in this embodiment, there are two charging ports 13 , one of which is located on the peripheral side of the charging base 10 , and the other is located on a side of the charging base 10 away from the first limiting hole 12 .

[0061] For another example, in other embodiments, the charging port 13 is located on the peripheral side of the charging base 10.

[0062] For another example, in other embodiments, the charging port 13 is located on the side of the charging base 10 facing away from the first limiting hole 12.

[0063] As Figure 11 and Figure 12 shown, the discharge rotary cover 70 and the discharge base 20 are rotatably arranged relative to each other. The discharge rotary cover 70 is provided with a discharge avoidance hole 71 corresponding to the discharge port 23.

[0064] In this solution, the specific position of the discharge avoidance hole 71 corresponds to the specific position of the discharge port 23. In this embodiment, there are two specific positions for the discharge port 23. One is on the peripheral side of the discharge base 20, and the other is on the end face of the discharge base 20. Either one or both can be selected.

[0065] For example, in combination with Figure 7 and Figure 8 shown, in this embodiment, the number of discharge ports 23 is two. One is located on the peripheral side of the discharge base 20, and the other is located on the side of the discharge base 20 facing away from the second limiting hole 22.

[0066] For another example, in other embodiments, the discharge port 23 is located on the peripheral side of the discharge base 20.

[0067] For another example, in other embodiments, the discharge port 23 is located on the side of the discharge base 20 facing away from the second limiting hole 22.

[0068] In addition, in order to enable the charging rotary cover 60 and the discharge rotary cover 70 to stably stay at the preset positions, that is, the joint positions, corresponding to the closing and opening of each port, magnetic attraction, card points and other methods can be used to achieve this.

[0069] Taking the magnetic attraction method as an example:

[0070] In combination with Figure 6 、 Figure 9 、and Figure 10As shown in the figure, a plurality of first magnetic members 14 are provided on the charging base 10. Each first magnetic member 14 is distributed at a preset joint position. The charging rotary cover 60 is provided with a second magnetic member 62. The second magnetic member 62 and the first magnetic member 14 are mutually adsorbed to control the charging rotary cover 60 to stay at one of the joint positions. By using the magnetic adsorption effect, the charging rotary cover 60 can be made to stay at the preset joint position, reducing the probability of displacement under non-artificial operation and improving reliability. In this embodiment, the number of the first magnetic members 14 is three, and their distribution positions respectively correspond to the positions where two charging ports 13 are opened and the position where all the charging ports 13 are closed. In addition, in this embodiment, the first magnetic member 14 is an iron core, and the second magnetic member 62 is a magnet.

[0071] Combined with Figure 8 、 Figure 11 、and Figure 12 As shown in the figure, a plurality of third magnetic members 24 are provided on the discharging base 20. Each third magnetic member 24 is distributed at a preset joint position. The discharging rotary cover 70 is provided with a fourth magnetic member 72. The fourth magnetic member 72 and the third magnetic member 24 are mutually adsorbed to control the discharging rotary cover 70 to stay at one of the joint positions. By using the magnetic adsorption effect, the discharging rotary cover 70 can be made to stay at the preset joint position, reducing the probability of displacement under non-artificial operation and improving reliability. In this embodiment, the number of the third magnetic members 24 is three, and their distribution positions respectively correspond to the positions where two discharging ports 23 are opened and the position where all the discharging ports are closed. In addition, in this embodiment, the third magnetic member 24 is an iron core, and the second magnetic member 62 is a magnet.

[0072] In addition, in order to improve the overall stability of the device, especially to strengthen the protection of the battery pack 40, as Figure 3 and Figure 4 shown, in this embodiment, the rotary mobile power supply 100 further includes: an inner bracket 80 connected to the charging base 10. The inner bracket 80 includes: a limiting ring 81 sleeving the battery pack 40 and a column 82 connected between the limiting ring 81 and the charging base 10. The inner bracket 80 is used to strengthen the limiting effect on the battery pack 40 to enhance the internal structural stability.

[0073] Brief description of the working principle:

[0074] As Figure 3 shown, the charging base 10, the battery pack 40, the circuit board 30, and the discharging base 20 form a combined structure distributed in a cylindrical shape. As Figure 1 and Figure 2As shown in the figure, further cover protection is carried out through the outer shell 50, the charging rotary cover 60, and the discharging rotary cover 70. When the battery pack 40 needs to be charged, by rotating the charging rotary cover 60, the charging port 13 is aligned with the charging avoidance hole 61, so that the charging port 13 can be exposed. On the contrary, only by misaligning the charging avoidance hole 61 with the charging port 13, the charging port 13 can be hidden, playing a protective role. Similarly, when the electronic product needs to be charged, by rotating the discharging rotary cover 70, the discharging port 23 is aligned with the discharging avoidance hole 71, so that the discharging port 23 can be exposed. On the contrary, only by misaligning the discharging avoidance hole 71 with the discharging port 23, the discharging port 23 can be hidden, playing a protective role.

[0075] The above-mentioned rotary mobile power supply 100 adopts a cylindrical and rotary structure, which compresses the overall space occupation area of the device. It is not only convenient to hold, but also convenient to put into the storage bag for daily travel, improving the convenience of carrying. At the same time, when charging or discharging is not required, the charging port 13 and the discharging port 23 can be hidden, reducing the probability of dust accumulation and rust, and reducing the risk of poor electrical contact.

[0076] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0077] The above embodiments only represent the preferred embodiments of the present invention, and the description is relatively specific and detailed, but it should not be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
