Description

Technical Field

[0001] The utility model relates to the technical field of electronic devices, in particular to a portable mobile power supply. Background Art

[0002] In the fast-paced modern life, mobile power supplies have become one of the indispensable electronic devices in people's daily lives. Especially in environments far from fixed power sources, such as during travel, outdoor adventures, or in emergency situations, mobile power supplies provide timely power support for portable electronic products such as mobile phones and tablet computers, greatly improving the convenience of life and work. However, traditional mobile power supplies often only consider the functions of electrical energy storage and output in their designs, ignoring the actual needs and convenience of users during the charging process.

[0003] Specifically, when the existing mobile power supply needs to be charged, users usually need to carry an additional dedicated charger or data cable to charge the mobile power supply itself. This not only increases the burden of carrying but also reduces the convenience of use. Especially in emergency situations, if users forget to carry the charger or data cable, the mobile power supply cannot be charged in time, which will in turn affect the normal use of other electronic devices.

[0004] To solve the above problems, although some mobile power supplies with integrated charging plugs have emerged on the market, most of these products adopt a fixed design and cannot be folded or stored. This not only increases the overall volume and weight of the mobile power supply, reducing portability, but also easily causes damage to the plug due to collision or extrusion during the carrying process, affecting the service life.

[0005] In addition, even if some mobile power supplies are designed with foldable plugs, due to the lack of reasonable limiting and supporting structures, the plugs are often not smooth enough during the folding and unfolding processes, and may even get stuck due to unreasonable structures, bringing inconvenience to users. Summary of the Utility Model

[0041] See Figures 1 to 11 As shown, the present utility model discloses a specific embodiment of a portable mobile power supply, including a mobile power supply main body 1, a connection component 2 and a folding plug 3. The connection component 2 is connected to the mobile power supply main body 1. The connection component 2 is provided with a slot 221, an inner arc-shaped limiting part 211 and an outer arc-shaped limiting part 222, and the outer arc-shaped limiting part 222 and the inner arc-shaped limiting part 211 are arranged in a staggered manner within the slot 221; the folding plug 3 is provided with a rotating shaft 31. The rotating shaft 31 is located within the slot 221, and one side of the rotating shaft 31 close to the mobile power supply main body 1 is rotatably connected to the outer arc-shaped limiting part 222, and the side of the rotating shaft 31 away from the mobile power supply main body 1 is rotatably connected to the inner arc-shaped limiting part 211.

[0042] Specifically, by providing the folding plug 3 on the mobile power supply main body 1, it enables users not to need to carry an additional independent charger to charge the mobile power supply when going out. Also, through the rotational connection design of the folding plug 3, when the user needs to charge the mobile power supply, simply unfolding the folding plug 3 from the connection component 2 and connecting it to a power socket can achieve the charging of the mobile power supply. And when the user does not need to charge the mobile power supply, the plug can be folded up, greatly reducing the overall volume and occupied space of the mobile power supply. This design makes the mobile power supply more portable and easy to put into a pocket, backpack or handbag, and is very suitable for daily travel and travel. At the same time, the foldable design of the folding plug 3 effectively avoids the risk of collision with external structures when not in use, reduces the damage caused by collision, improves the service life of the folding plug 3, and through the staggered arrangement of the inner arc-shaped limiting part 211 and the outer arc-shaped limiting part 222 within the slot 221, it makes the rotation of the rotating shaft 31 within the slot 221 smoother, reduces friction and resistance, and improves the folding and unfolding efficiency of the folding plug 3.

[0043] Preferably, an installation cavity 11 is provided on the main body 1 of the mobile power supply, and the connection assembly 2 is installed in the installation cavity 11. The setting of the installation cavity 11 avoids additional space occupation, makes the volume of the mobile power supply more compact, facilitates carrying and storage, and realizes the integrated design of the overall structure. This design not only makes the appearance of the mobile power supply more tidy and beautiful, but also reduces the exposure of components and improves the overall texture of the product.

[0044] See Figures 4 to 7 As shown, in a specific embodiment, the folding plug 3 includes two plug pieces 32, and the two plug pieces 32 are arranged in parallel at both ends of the rotating shaft 31. A receiving groove 223 is also provided on the connection assembly 2. When the folding plug 3 is in the folded state, the plug pieces 32 are received in the receiving groove 223.

[0045] Specifically, the plug pieces 32 are protected by the receiving groove 223 in the folded state, avoiding direct contact with the external environment, reducing physical damage caused by collision, scratching, etc., and thus improving the durability of the folding plug 3.

[0046] See Figure 4 、 Figure 5 、 Figure 7 and Figure 8 As shown, in a specific embodiment, the connection assembly 2 includes a connection base 21 and a connection outer frame 22. The connection base 21 is connected to the installation cavity 11, the connection outer frame 22 is connected to the connection base 21, and the receiving groove 223, the slot 221 and the outer arc-shaped limiting portion 222 are all provided on the connection outer frame 22, and the inner arc-shaped limiting portion 211 is provided on the connection base 21.

[0047] Specifically, the slot 221 and the outer arc-shaped limiting portion 222 are provided at the lower end of the connection outer frame 22, and the outer arc-shaped limiting portion 222 is provided at both ends of the slot 221. The inner arc-shaped limiting portion 211 is provided at the lower end of the connection base 21, and the inner arc-shaped limiting portion 211 extends into the slot 221 so that a rotation groove (not shown in the figure) is formed between the slot 221, the outer arc-shaped limiting portion 222 and the inner arc-shaped limiting portion 211. Both ends of the rotating shaft 31 are rotatably connected to the outer arc-shaped limiting portion 222, and the middle of the rotating shaft 31 is rotatably connected to the inner arc-shaped limiting portion 211. By rotatably connecting both ends of the rotating shaft 31 to the outer arc-shaped limiting portion 222 and rotatably connecting the middle of the rotating shaft 31 to the inner arc-shaped limiting portion 211, this design ensures the precise positioning of the rotating shaft 31 during rotation, avoids shaking or deviation, and further improves the stability and service life of the folding plug 3. At the same time, when it is necessary to replace the folding plug 3 or the electrical connection member 23, only need to disassemble the connection outer frame 22 and the connection base 21, and then the folding plug 3 or the electrical connection member 23 can be taken out, which is convenient for replacing the folding plug 3 or the electrical connection member 23.

[0048] In a specific embodiment, the connection component 2 further includes an electrical connector 23. The electrical connector 23 is installed between the connection base 21 and the connection outer frame 22. One end of the electrical connector 23 extends into the mobile power supply main body 1 and is connected to the circuit board inside the mobile power supply main body 1, and the other end of the electrical connector 23 is connected to the insertion piece 32.

[0049] Specifically, the electrical connector 23 is in a J shape and is a conductive metal elastic sheet to ensure that the insertion piece 32 can maintain good contact with the electrical connector 23 during rotation, thereby ensuring stable transmission of current.

[0050] In a specific embodiment, the connection base 21 is further provided with a first elastic support member 212 and a second elastic support member 213. The first elastic support member 212 and the second elastic support member 213 extend into the slot 221. The first elastic support member 212 abuts above the rotating shaft 31, and the second elastic support member 213 abuts below the rotating shaft 31 to reduce the gap between the rotating shaft 31 and the rotating groove, thereby making the connection structure between the rotating shaft 31 and the rotating groove more stable. Preferably, both the first elastic support member 212 and the second elastic support member 213 abut against the middle of the rotating shaft 31. The number of the inner arc-shaped limiting portions 211 and the outer arc-shaped limiting portions 222 is both set to 2, and the inner arc-shaped limiting portions 211 and the outer arc-shaped limiting portions 222 are evenly distributed on both sides of the first elastic support member 212 and the second elastic support member 213, so that the rotating shaft 31 is stably supported, thereby effectively preventing the rotating shaft 31 from accidentally moving or loosening when subjected to an external force.

[0051] See Figures 9 to 11 As shown, in a specific embodiment, the portable mobile power supply further includes an adapter plug 4. The adapter plug 4 is snap-connected to the connection component 2 and the folding plug 3.

[0052] Specifically, the adapter plug 4 includes multiple different types. By providing multiple different types of adapter plugs 4 (such as European standard, American standard, British standard, Australian standard, etc.), the mobile power supply can be adapted to the socket standards of most countries and regions in the world, so that users can select different types of adapter plugs 4 according to needs and snap them onto the connection component 2 to adapt to different types of charging interfaces, greatly improving the convenience of international use of the mobile power supply. Moreover, the snap-connection structure formed by the adapter plug 4, the connection component 2 and the folding plug 3 also facilitates the replacement of the adapter plug 4.

[0053] In a specific embodiment, the adapter plug 4 includes an adapter base 41 and pins 42 installed on the adapter base 41. The adapter base 41 extends with a plug-in portion 411. The plug-in portion 411 is provided with a plug-in slot 4111 for plugging the insertion piece 32. One end of the pin 42 extends into the plug-in slot 4111, and the pin 42 is used to connect the insertion piece 32.

[0054] Specifically, when using the adapter plug 4, the insertion piece 32 is rotated to the closed position to hide it in the receiving groove 223, and the insertion part 411 of the adapter plug 4 is inserted into the receiving groove 223. At this time, the insertion piece 32 is inserted into the insertion slot 4111 and electrically connected to the pin 42, so that the adapter plug 4 can be used to plug into the socket of the corresponding country to charge the mobile power supply.

[0055] See Figures 7 to 11 As shown, in a specific embodiment, the connecting outer frame 22 is provided with a limiting member 224. The number of the insertion parts 411 is two, and a limiting groove 412 is formed between the two insertion parts 411. The limiting groove 412 is clamped to the limiting member 224.

[0056] Specifically, a limiting strip 4112 is provided on one side of the insertion part 411 close to the limiting groove 412, and limiting notches 2241 corresponding to the limiting strip 4112 are provided on both sides of the limiting member 224, so that the cross section of the limiting member 224 is in the shape of an I-beam, which helps to quickly and accurately locate the assembly positions of the adapter base 41, the connecting component 2 and the folding plug 3 during assembly, reduces the assembly error and assembly time, and the I-shaped limiting member 224 provides a larger contact area between the limiting member 224 and the insertion part 411, which makes the connection between the limiting member 224 and the adapter plug 4 more stable. This stable connection can reduce the risk of the adapter plug 4 loosening or falling off, and ensure the stability and safety of charging.

[0057] In a specific embodiment, a limiting protrusion 41121 is further provided below the limiting strip 4112, and the limiting protrusion 41121 is used to abut against the lower part of the limiting member 224.

[0058] Specifically, the limiting member 224 is made of elastic plastic material. When the limiting protrusion 41121 moves along the limiting strip 4112 towards the direction close to the slot 221, the limiting notch 2241 deforms so that the limiting protrusion 41121 can continue to move. When the limiting protrusion 41121 moves below the limiting member 224, the limiting notch 2241 returns to its original shape so that the limiting protrusion 41121 abuts between the limiting member 224 and the rotating shaft 31, thereby making the connection structure between the adapter plug 4, the connecting component 2 and the insertion piece 32 more stable, and effectively preventing loosening between the adapter plug 4, the connecting component 2 and the insertion piece 32 to ensure the stability and safety of charging.

[0059] See Figure 6As shown, in a specific embodiment, the first elastic support member 212 abuts against the lower part of the limiting member 224. A first limiting surface 311 and a second limiting surface 312 which are vertically connected are provided in the axial direction of the rotating shaft 31. When the folding plug 3 is in the retracted state, the first limiting surface 311 abuts against the lower part of the first elastic support member 212, and the second limiting surface 312 rotates to the outside of the connecting outer frame 22. When the folding plug 3 is in the unfolded state, the first limiting surface 311 rotates to the outside of the connecting outer frame 22, and the second limiting surface 312 abuts against the connecting outer frame 22.

[0060] Specifically, by providing the vertically connected first limiting surface 311 and second limiting surface 312 on the rotating shaft 31, the situation that the insertion piece 32 is damaged due to excessive rotation of the rotating shaft 31 can be effectively avoided, thereby improving the service life of the folding plug 3.

[0061] See Figures 7 to 11 As shown, in a specific embodiment, the adapter base 41 further has a first height limiting portion 413, and the limiting member 224 further has a height limiting groove 2242 corresponding to the first height limiting portion 413.

[0062] Specifically, the first height limiting portion 413 is telescopically arranged in the adapter base 41. When the adapter plug 4 is to be clamped to the connecting component 2, first retract the first height limiting portion 413, and then install the adapter plug 4 on the connecting component 2 along the limiting notch 2241. When the first height limiting portion 413 moves to the height limiting groove 2242, then extend the first height limiting portion 413 so that the first height limiting portion 413 is inserted into the height limiting groove 2242 to fix the clamping height of the adapter plug 4 and the connecting component 2. When it is necessary to remove the adapter plug 4, first retract the first height limiting portion 413 and disengage it from the height limiting groove 2242, and then move the adapter plug 4 out of the connecting component 2 along the limiting notch 2241. Through the above-mentioned first height limiting portion 413 and height limiting groove 2242, the clamping height of the adapter plug 4 and the connecting component 2 is fixed, so that the connection structure between the adapter plug 4 and the connecting component 2 is more stable and it is convenient to replace the adapter plug 4.

[0063] In a specific embodiment, the adapter base 41 further has a button 414, and the button 414 is used to control the telescoping of the first height limiting portion 413.

[0064] Specifically, the button 414 is arranged on the side of the adapter base 41 away from the first height limiting portion 413 to facilitate the pressing operation of the button 414. By pressing the button 414, the first height limiting portion 413 is switched between the extended state and the retracted state, which is convenient for controlling the first height limiting portion 413. In other embodiments, the first height limiting portion 413 can also be installed in the adapter base 41 through elastic structures such as springs and elastic sheets to realize the automatic telescoping of the first height limiting portion 413, and the structure is simple and stable.

[0065] In a specific embodiment, the adapter 41 is further provided with a second height limiting portion 415 , which is located above the first height limiting portion 413 ; when the first height limiting portion 413 is inserted into the height limiting groove 2242 , the second height limiting portion 415 abuts against the upper end of the limiting member 224 .

[0066] Specifically, the second height limiting portion 415 is provided on the basis of the first height limiting portion 413, and an additional locking mechanism is added; when the first height limiting portion 413 is successfully inserted into the height limiting groove 2242 to achieve preliminary locking, the second height limiting portion 415 further abuts against the upper end of the position limiting member 224, forming a double locking. This design significantly enhances the connection stability between the adapter 41 and the position limiting member 224, reduces the risk of loosening or falling off due to external factors (such as vibration, shaking), and at the same time, the second height limiting portion 415 limits the distance that the plug portion 411 continues to move downward, thereby avoiding damage to the adapter plug 4 and the connection assembly 2 due to excessive insertion of the plug portion 411, and extending the service life of the mobile power supply.

[0067] See also Figures 1 to 3 As shown, in a specific embodiment, the mobile power source body 1 is also connected to a power transmission line 5 .

[0068] Specifically, by integrating the folding plug 3, the adapter plug 4 and the power line 5 on the mobile power supply, the mobile power supply can meet multiple charging needs such as charging the mobile power supply body 1 alone, charging external devices alone, and charging external devices as a power adapter, without the need to carry or find the power line 5 additionally, thereby greatly improving the convenience of use and the portability of travel. The design of the built-in power line 5 reduces the number of plug-in and unplugging times between the power line 5 and the mobile power supply, thereby reducing the risk of interface wear and loosening caused by frequent plug-in and unplugging, and improving the safety of use. It can be understood that the power line 5 can charge multiple types of devices.

[0069] In a specific embodiment, a receiving slot 12 is further provided on the mobile power source body 1 , and the power line 5 is received in the receiving slot 12 , and both ends of the power line 5 are provided with snap-on terminals 51 corresponding to the receiving slot 12 .

[0070] Specifically, by providing the storage groove 12, the transmission line 5 can be effectively prevented from being entangled, which facilitates the storage of the transmission line 5. At the same time, the transmission line 5 can be effectively protected, thereby maintaining the cleanliness and hygiene of the transmission line 5 and avoiding damage to the transmission line 5. Moreover, by providing the snap-in end 51, there is no need to snap the entire transmission line 5 into the storage groove 12, which reduces the production consumables of the transmission line 5, thereby reducing the production cost, and can also reduce the friction between the transmission line 5 and the storage groove 12, thereby facilitating the removal of the transmission line 5.

[0071] In a specific embodiment, the mobile power supply body 1 is further provided with a plurality of power transmission interfaces 13, so that the mobile power supply body 1 can charge multiple devices simultaneously, improving the practicability of the mobile power supply.

[0072] The above embodiments are the preferred implementation solutions of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
