Description

Technical Field

[0001] This application relates to the field of power bank technology, and in particular to a power bank with an integrated storage component. Background Technology

[0002] A power bank, also known as a portable charger or power bank, is a portable charger that can be carried by an individual and stores its own electrical energy. It is mainly used to charge consumer electronic products such as handheld mobile devices (e.g., cordless phones, laptops), especially in situations where there is no external power supply.

[0003] Existing power banks come in two types: one with an integrated cable (the cable and power bank are integrated), often available for rental; and another without an integrated cable (the cable and power bank are separate). Integrated power banks have long, exposed cables that are inconvenient to store, while separate power banks require carrying the cable separately, which also causes inconvenience. Therefore, this invention proposes a power bank with an integrated storage component to at least partially solve the problems inherent in the prior art. Utility Model Content

[0004] In view of the aforementioned problems, this application is made to provide a power bank with an integrated storage component that overcomes or at least partially solves the aforementioned problems.

[0005] One embodiment of this application discloses a power bank with an integrated storage component, including:

[0006] The housing has a rear cover at its first end, and inside it are a battery cell assembly and a take-up device;

[0007] The take-up device is wound with a conductor, the first end of which is electrically connected to the battery cell assembly;

[0008] The second end of the conductor is electrically connected to a power supply connector and extends out of the rear cover through the outlet on the rear cover, and the power supply connector is larger than the outlet.

[0009] Optionally, a protective layer is also provided at the location where the wire connects to the power supply connector.

[0010] Optionally, the back cover is provided with an inwardly recessed storage groove, the length of which is greater than the length of the protective layer plus the power supply connector;

[0011] Furthermore, the storage slot and protective layer are equipped with magnetic attracting elements.

[0012] Optionally, the second end of the housing is further provided with a front cover;

[0013] The front cover is provided with a charging port; the electrodes in the charging port are electrically connected to the battery cell assembly.

[0014] Optionally, the housing is provided with function buttons on its side;

[0015] The function button is electrically connected to the battery cell assembly.

[0016] Optionally, both the charging port and the power connector are USB interfaces.

[0017] Optionally, the battery cell assembly includes a main control board and at least one battery pack;

[0018] The battery pack is electrically connected to the main control board.

[0019] Optionally, a sensor is also provided inside the outlet, and markings for identification are provided near both ends of the wire;

[0020] The main control board is equipped with a trigger circuit that is electrically connected to the sensor, which is used to trigger the connection status between the wire and the main control board.

[0021] This application has the following advantages:

[0022] In the embodiments of this application, the casing has a rear cover at its first end, inside which a battery cell assembly and a cable retractor are housed. The cable retractor has a wire wound around it, with the first end of the wire electrically connected to the battery cell assembly. The second end of the wire is electrically connected to a power connector and extends out of the rear cover through a cable outlet, with the power connector being larger than the cable outlet. By winding the wire around the cable retractor and integrating it into the power bank casing, the problems of exposed and inconveniently stored wires in traditional integrated power banks and the need for additional carrying and storage of wires in detachable power banks are solved. The power connector being larger than the cable outlet prevents the wire from completely retracting into the casing, making it easier for the user to access. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] Reference Figures 1 to 4 This application provides a power bank with an integrated storage component, comprising: a shell 101, a back cover 103 at its first end, and a battery cell assembly and a cable retractor 201 inside the shell; the cable retractor 201 is wound with a wire 202, the first end of the wire 202 being electrically connected to the battery cell assembly; the second end of the wire 202 being electrically connected to a power supply connector 204, and extending out of the back cover 103 through a cable outlet 104 on the back cover 103, wherein the power supply connector 204 is larger than the cable outlet 104.

[0031] By winding the cable 202 onto the retractor 201 and integrating it into the power bank housing 101, the problems of exposed cables and inconvenient storage in traditional integrated power banks, as well as the need for separate carrying and storage of cables in detachable power banks, are solved. The power connector 204 is larger than the cable outlet 104, preventing the cable 202 from completely retracting into the housing 101, making it easier for users to access. When carrying the power bank out, users do not need to worry about the excessively long cable 202 getting tangled in other items, nor do they need to carry the cable separately. When needed, the cable can be pulled out directly from the cable outlet 104 on the back cover 103, and the cable 202 can be retracted after use, making it simple and convenient.

[0032] In some embodiments of this application, a protective layer 203 is further provided at the connection point between the wire 202 and the power connector 204. Providing a protective layer 203 at the connection point enhances the structural strength of this area, preventing breakage at the connection point due to frequent bending, extending the lifespan of the power bank, and improving product reliability. For example, during repeated plugging and unplugging of the power connector 204 and pulling of the wire 202, the protective layer 203 can buffer and protect the connection, preventing poor contact or wire breakage.

[0033] Furthermore, the rear cover 103 is provided with an inwardly recessed storage groove 105, the length of which is greater than the length of the protective layer 203 plus the power connector 204; and the storage groove 105 and the protective layer 203 are provided with magnetic attracting elements. For example, a magnet can be placed in the storage groove 105, while the protective layer 203 can be provided with a magnet with opposite magnetic poles, an iron sheet, or a material that can be attracted by a magnet. Alternatively, a magnet can be placed in the protective layer 203, and a corresponding iron sheet or a material that can be attracted by a magnet, such as silicon steel sheet, nickel sheet, or other magnetically affinity materials, can be placed in the storage groove 105.

[0034] By providing a storage slot 105 in the back cover 203, with a length greater than the combined length of the protective layer 203 and the power connector 204, a neat space is provided for storing the cable 202. The magnetic components in the storage slot 105 and the protective layer 203 allow the power connector to be securely attached to the storage slot, further improving the stability of cable storage, preventing the cable 202 from becoming loose, and facilitating quick location and retrieval by the user. For example, after the cable 202 is retracted, the power connector 204 is magnetically attached to the storage slot, so even if the power bank shakes in the backpack, the cable will not easily come apart; when needed, it can be easily removed with a gentle pull.

[0035] In some embodiments of this application, the second end of the housing 101 is further provided with a front cover 102; the front cover 103 is provided with a charging port 304; the electrodes in the charging port 304 are electrically connected to the battery cell assembly. The front cover 102, with its charging port 304 and electrodes electrically connected to the battery cell assembly, enables the power bank to have a charging function, replenishing its own power and improving its basic functions, thus meeting the user's bidirectional charging and discharging needs. The front cover 102 can be detachably connected to the housing 101 via clips or screws, facilitating assembly during production. Furthermore, the main control board 301 of the battery cell assembly or the charging port 304 can be connected to the housing 101 before connecting the front cover 102 to the housing 101, improving assembly efficiency. When the power bank's power is low, the user can connect a charging cable through the charging port 304 to charge it, ensuring continued use.

[0036] Furthermore, a function button 303 is provided on the side of the housing 101; the function button 303 is electrically connected to the battery cell assembly. The function button can be used to display the battery level or to automatically control the retractor 201 to retract the cable. The conductor 202 can be a flat wire or a round wire; in this application, a flat wire is preferred. The retractor 201 can be equipped with a motor, which can be controlled automatically to retract the cable via the function button 303. For example, it can be set to automatically retract the cable when the function button 303 is pressed and held for more than 3 seconds. The function button 303 on the side of the housing 101 and electrically connected to the battery cell assembly allows users to perform operations such as turning the power bank on and off and checking the battery level, facilitating user control and management of the power bank and improving the user experience. By pressing the function button 303, users can quickly check the remaining battery level of the power bank for reasonable usage planning. Alternatively, the function button 303 can also be located on the front cover 102.

[0037] It should be noted that the above-mentioned take-up device 201 is also called a telescopic reel. Its structural principle can be similar to the spring principle of a measuring tape, or it can be driven by a micro motor and can be electrically controlled to take up the line. The above-mentioned wire 202 uses flat wire, which can better perform winding and unwinding.

[0038] In some embodiments of this application, both the charging port 304 and the power connector 204 are USB interfaces. Preferably, a Type-C interface is used for the USB interface, which not only facilitates cable removal, but also provides broad versatility, allowing compatibility with most electronic devices on the market. Current electronic devices, whether mobile phones, tablets, or other devices supporting USB charging, can easily connect to this power bank for charging.

[0039] It should be noted that the Type-C interface, also known as USB Type-C, is a USB interface form factor standard. It is smaller than both Type-A and Type-B, and can be used in both PCs (host devices) and external devices (slave devices, such as mobile phones). USB Type-C has 4 pairs of TX / RX pins, 2 pairs of USB D+ / D- pins, 1 pair of SBU pins, 2 CC pins, 4 VBUS pins, and 4 ground pins.

[0040] In some embodiments of this application, the battery cell assembly includes a main control board 301 and at least one battery pack 302; the battery pack 302 is electrically connected to the main control board 301. The battery cell assembly includes a main control board 301 and at least one battery pack 302. The main control board 301 manages and controls the battery packs, realizing functions such as charging and discharging, and power display of the power bank, ensuring the normal and stable operation of the power bank. It is the core component combination for the power bank to achieve energy storage and output. The main control board 301 rationally controls the charging and discharging process according to the power status of the battery packs, and simultaneously provides power information to the user through indicator lights and other means. The battery packs are preferably lithium-ion batteries, which have the advantages of small size and large capacity.

[0041] Furthermore, a sensor is also provided inside the outlet 104, and identification marks are provided near both ends of the wire 202. The main control board 301 is provided with a trigger circuit electrically connected to the sensor to control the connection state between the trigger wire 202 and the main control board 301. For example, when the sensor detects the mark, a transistor can be connected to make the transistor conduct and generate a current signal. This current signal connects the wire 202 to the main control board 301; otherwise, the connection is not established. The sensor can be a laser sensor or a Hall sensor. A metal trigger, such as one made of iron, can be placed at the mark position. When the mark is located at the sensor position, the Hall sensor is triggered.

[0042] The aforementioned retractor 201, in conjunction with the aforementioned sensor, ensures that the circuit can only be connected when the lead wire 202 is fully extended; otherwise, the circuit remains closed. This is to prevent the inductive effect that can easily form when the lead wire 202 is coiled, thus ensuring the safety and stability of the charging process. Furthermore, the sensor's discontinuation of the circuit when the lead wire 202 is not fully extended effectively prevents safety hazards and charging anomalies caused by inductive effects.

[0043] A sensor is installed inside the aforementioned outlet 104, and identification marks are set at both ends of the wire 202. Together with the trigger circuit on the main control board 301, the connection state between the wire 202 and the main control board 301 can be precisely controlled. Connection is only established when the wire 202 is fully extended, further eliminating the risk of inductive effects and improving the safety and reliability of the power bank. For example, if the user does not fully pull out the wire 202, the sensor detects that the identification marks have not been completely removed, and the trigger circuit does not conduct, preventing inductive effects caused by the wire 202 coiling from affecting charging or damaging the device. When the wire 202 is fully extended, the sensor detects the corresponding mark, the trigger circuit conducts, and the power bank supplies power normally.

[0044] Although preferred embodiments of the present application have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.

[0045] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device.
