Description

Technical Field

[0001] This invention relates to the field of charging facilities, and more particularly to a portable power bank with a built-in tail plug. Background Technology

[0002] A power bank, also known as a portable charger, is a convenient, high-capacity power source for charging. It's a portable device that integrates energy storage and charging management, primarily used to charge mobile devices anytime, anywhere. A power bank consists of multiple batteries, allowing for flexible voltage and capacity configurations to meet the charging needs of different devices.

[0003] Power banks typically come with a built-in charging cable for connecting to mobile devices. However, most existing power banks are cube-shaped, which means they can only be carried inside a backpack or similar item. If the user isn't carrying a backpack or similar item, they have to hold the power bank by hand, which is quite inconvenient and makes it less convenient to carry. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a portable power bank with a built-in tail plug for instant charging.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a portable power bank with a built-in tail plug, comprising multiple batteries, with wires connecting the multiple batteries, a tail plug connected to one end of the battery, and protective shells fixedly installed on the outer sides of the multiple batteries. The wires and tail plug extend from the outer surface of the protective shells. A locking strap is provided in the middle of the protective shell at one end, and a rubber band is fixedly installed in the middle of the protective shell at the other end. The rubber band wraps around the outer surface of the tail plug. Shell lugs extend from one edge at both ends of the multiple protective shells except at one end, and L-shaped connectors extend from the other edge at both ends of the multiple protective shells except at the other end. The shell lugs fit into the L-shaped connectors, and a shifting post extends from the shell lugs relative to the end face of the L-shaped connector. A shifting hole is provided through the middle of the L-shaped connector, and the shifting post is slidably installed inside the shifting hole. Rubber locking blocks are provided on the upper and lower end faces of the shifting hole.

[0006] Preferably, the upper and lower end faces of the displacement hole are provided with fixing grooves, the rubber locking block is fixed inside the fixing groove, and the outer surface of the displacement column is symmetrically provided with two triangular locking grooves, the end of the rubber locking block is adapted to the triangular locking groove.

[0007] Preferably, the side of the displacement column extends with a limiting protective ear, and the inner side of the displacement hole is provided with a limiting protective groove, with the limiting protective ear located inside the limiting protective groove.

[0008] Preferably, the outer surface of the protective shell is provided with a blind groove on the outside of the wire, the upper and lower ends of the rubber strip are provided with No. 2 anti-slip texture, the plug of the tail plug is fitted with a rubber cap, and the rubber cap is connected to the rubber strip.

[0009] Preferably, the end of the rubber strip extends to a connecting post, and a cap lug is slidably installed on the outer surface of the connecting post. The end of the cap lug is fixed to the rubber protective cap, and the cap lug and the rubber protective cap are integrally formed. The end of the connecting post extends to an anti-slip cap, and the anti-slip cap is integrally formed with the connecting post. The upper and lower end faces of the rubber protective cap are provided with a first anti-slip texture.

[0010] Preferably, the locking strap includes a locking seat fixedly installed in the middle of the protective shell at one end, the rubber strap is inserted into the interior of the locking seat, a stepped hole is provided at the front end of the interior of the locking seat, a fixing pin is slidably installed in the small diameter section of the stepped hole, and the fixing pin passes through the front end of the rubber strap.

[0011] Preferably, the rubber belt has a plurality of adapting holes evenly distributed near the edge at its front end. The fixing pin is inserted into the interior of one of the adapting holes. The end of the fixing pin extends coaxially with a protruding cap. The protruding cap is slidably installed in the large diameter section of the stepped hole. A belt spring is fixedly installed at the front end of the interior of the stepped hole. The end of the belt spring is fixed to the front end of the protruding cap.

[0012] Preferably, the upper surface of the locking seat is provided with a groove, and a moving groove is provided between the groove and the stepped hole. A toggle frame is slidably installed inside the moving groove. One end of the toggle frame is fixed to the protruding cap, and the other end of the toggle frame passes through the inside of the groove. The toggle frame slides in cooperation with the groove, and a toggle cap is fixedly installed at the other end of the toggle frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By forcefully manipulating multiple protective shells in sequence, the rubber locking block deforms and disengages from the triangular locking groove. This allows the shifting post to slide within the shifting hole, moving from one end to the other, creating a gap between adjacent shells. The shells can then be placed on the wrist. The shifting post rotates within the shifting hole, transforming the shells into a ring shape, allowing them to fit snugly on the wrist and improving portability by eliminating the need to hold the power bank. Conversely, by forcefully manipulating the shells in the opposite direction, adjacent shells come together. The shifting post then slides within the shifting hole to the rubber locking block, which re-engages in the triangular locking groove on the shifting post, transforming the shells into a block shape for easy storage. This allows for flexible conversion of the power bank into a ring or block shape to meet different usage needs.

[0015] 2. By moving the lever cap, the lever frame can be driven to slide in the moving groove, which in turn drives the fixing pin to slide in the stepped hole, causing the fixing pin to retract into the stepped hole. At this time, the strap spring deforms. Then, the rubber strap is inserted into the inside of the locking seat, and the lever cap is released. At this time, the strap spring returns to its original state and pushes the fixing pin into the adaptation hole on the rubber strap to lock the rubber strap in the locking seat, thereby binding the protective shell to the wrist. The process is simple to operate and effectively facilitates use. At the same time, by allowing the fixing pin to be inserted into the adaptation hole at different positions on the rubber strap, it can adapt to the wrists of different sizes for wearing.

[0025] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0026] like Figures 1-8The illustrated portable power bank with a built-in charging port includes multiple batteries 5, connected by wires 2. The wires 2 connect the batteries 5 together. A charging port 15 is connected to one end of each battery 5, facilitating charging with mobile devices. Since this connection is existing technology and widely used, it is not described in detail here. Each battery 5 is fixedly fitted with a protective shell 1, which serves to support and protect the battery. The wires 2 and the charging port 15 extend from the outer surface of the protective shell 1. 2. Waterproof adhesive is applied to the connection between the tail plug 15 and the housing 1 to seal it and prevent water from entering. A locking strap is provided in the middle of the housing 1 at one end, and a rubber band 3 is fixedly installed in the middle of the housing 1 at the other end. The rubber band 3 wraps around the outer surface of the tail plug 15. The rubber band 3 serves to protect the tail plug 15 and facilitates wearing. Except for the housing 1 at one end, each of the multiple housing 1 at both ends has a housing lug 8 extending from one edge. Except for the housing 1 at the other end, each of the multiple housing 1 at both ends has an L-shaped connector 7 extending from the other edge. The shell lug 8 extends from the end face of the L-shaped connector 7 to form a displacement post 10 that fits into the L-shaped connector 7. The shell lug 8 supports the displacement post 10. A displacement hole 9 is provided through the middle of the L-shaped connector 7. The displacement post 10 is slidably installed inside the displacement hole 9. The displacement hole 9 allows the displacement post 10 to slide left and right, thus creating a certain gap between the multiple shells 1. This allows the multiple shells 1 to be transformed into a ring shape to fit on the wrist. At the same time, it also allows the multiple shells 1 to be fitted together to form a block shape for easy storage. Rubber locking blocks are provided on the upper and lower end faces of the interior of the displacement hole 9. 14. By forcefully moving multiple protective shells 1 in sequence, the rubber locking block 14 can be deformed to disengage from the interior of the triangular locking groove 11. This allows the shifting post 10 to slide within the shifting hole 9 without the constraint of the rubber locking block 14, moving from one end of the shifting hole 9 to the other, creating a certain gap between adjacent protective shells 1. The protective shell 1 can then be placed on the wrist. At this time, the shifting post 10 rotates within the shifting hole 9, causing multiple protective shells 1 to transform into a ring shape, thus attaching to the wrist for wearing. This avoids the need to carry a power bank by hand, effectively improving portability.

[0027] The upper and lower end faces of the displacement hole 9 are provided with fixing grooves 28. The rubber locking block 14 is fixed inside the fixing groove 28. The fixing groove 28 serves to support the rubber locking block 14. The outer surface of the displacement column 10 is symmetrically provided with two triangular locking grooves 11. The end of the rubber locking block 14 is adapted to the triangular locking groove 11, so that the rubber locking block 14 can be fully inserted into the triangular locking groove 11 to fix the displacement column 10. By pushing multiple protective shells 1 in the opposite direction, two adjacent protective shells 1 can be brought together. At this time, the displacement column 10 will slide in the displacement hole 9 to the rubber locking block 14. At the same time, the rubber locking block 14 is re-inserted into the triangular locking groove 11 on the displacement column 10 to restrict it, so that multiple protective shells 1 are transformed into a block shape for easy storage.

[0028] The side of the shifting post 10 extends into a limiting protective ear 13, and the inner side of the shifting hole 9 is provided with a limiting protective groove 12. The limiting protective ear 13 is located inside the limiting protective groove 12. The cooperation between the limiting protective ear 13 and the limiting protective groove 12 can limit the rotation angle of the protective shell 1 to avoid excessive rotation and pulling on the wire 2.

[0029] The outer surface of the protective shell 1 is provided with a blind groove 6 on the outside of the wire 2. When multiple protective shells 1 are attached to each other and gathered together, the wire 2 will bend under the push and be stored in the blind groove 6, so that the protective shells 1 will not squeeze the wire 2 after they are attached to each other. The upper and lower ends of the rubber strip 3 are provided with second anti-slip texture 31, which plays an anti-slip role. A rubber cap 18 is inserted into the plug of the tail plug 15. The rubber cap 18 plays a role in covering and protecting the plug of the tail plug 15. The rubber cap 18 is connected to the rubber strip 3.

[0030] A connecting post 16 extends from the end of the rubber belt 3. A cap lug 29 is slidably installed on the outer surface of the connecting post 16. The connecting post 16 serves to allow the cap lug 29 to slide. The end of the cap lug 29 is fixed to the rubber cap 18. The cap lug 29 and the rubber cap 18 are integrally formed. An anti-slip cap 17 extends from the end of the connecting post 16. The anti-slip cap 17 serves to prevent the rubber cap 18 from separating from the rubber belt 3. The anti-slip cap 17 is integrally formed with the connecting post 16. The upper and lower end faces of the rubber cap 18 are provided with a first anti-slip texture 30. The first anti-slip texture 30 serves to prevent slippage.

[0031] The locking strap component includes a locking seat 4 fixedly installed in the middle of the protective shell 1 at one end. The rubber strap 3 is inserted into the interior of the locking seat 4. The locking seat 4 serves to engage with the rubber strap 3. A stepped hole 19 is provided at the front end of the interior of the locking seat 4. A fixing pin 22 is slidably installed on the small diameter section of the stepped hole 19. The stepped hole 19 serves to accommodate the fixing pin 22. The fixing pin 22 passes through the front end of the rubber strap 3 and serves to fix the rubber strap 3 inside the locking seat 4.

[0032] Multiple adaptable holes 23 are evenly distributed near the edge of the front end of the rubber band 3. A fixing pin 22 is inserted into one of the adaptable holes 23. By inserting the fixing pin 22 into the adaptable holes 23 at different positions on the rubber band 3, it can accommodate wrists of different sizes. The end of the fixing pin 22 extends coaxially with a protruding cap 21, which is slidably installed in the large-diameter section of the stepped hole 19. The cooperation between the protruding cap 21 and the stepped hole 19 can prevent the fixing pin 22 from dislodging from the stepped hole 19. A fixing pin is fixedly installed at the front end of the interior of the stepped hole 19. With spring 20, the end of the fixed spring 20 is fixed to the front end of the protruding cap 21. The cap 26 is turned to drive the actuating frame 25 to slide in the moving groove 24, thereby driving the fixing pin 22 to slide in the stepped hole 19, so that the fixing pin 22 retracts into the stepped hole 19. At this time, the fixed spring 20 deforms. Then the rubber band 3 is inserted into the inside of the locking seat 4 and the cap 26 is released. At this time, the fixed spring 20 returns to its original state and pushes the fixing pin 22 to engage in the adaptation hole 23 on the rubber band 3, so as to lock the rubber band 3 in the locking seat 4, thereby binding the protective shell 1 to the wrist.

[0033] The upper surface of the locking seat 4 is provided with a groove 27, which allows the actuating frame 25 to extend from the locking seat 4. A moving groove 24 is provided between the groove 27 and the stepped hole 19, which allows the actuating frame 25 to move normally. The actuating frame 25 is slidably installed inside the moving groove 24. One end of the actuating frame 25 is fixed to the extension cap 21, and the other end of the actuating frame 25 passes through the inside of the groove 27. The actuating frame 25 and the groove 27 are slidably engaged. A actuating cap 26 is fixedly installed at the other end of the actuating frame 25, which facilitates the actuation of the actuating frame 25.

[0034] In use, by forcefully turning multiple protective shells 1 in sequence, the rubber locking block 14 deforms and disengages from the triangular locking groove 11. This allows the shifting post 10 to slide within the shifting hole 9 without the constraint of the rubber locking block 14, moving from one end to the other and creating a gap between adjacent protective shells 1. The protective shell 1 can then be placed on the wrist. The shifting post 10 rotates within the shifting hole 9, transforming the multiple protective shells 1 into a ring shape, thus adhering to the wrist. Next, the lever cap 26 is turned to drive the lever frame 25 to slide within the moving groove 24, thereby causing the fixing pin 22 to slide within the stepped hole 19, retracting the fixing pin 22 into the stepped hole 19. At this point, the fixed band spring 20 deforms. Then, the rubber band 3 is inserted into the locking seat 4, and the lever cap 26 is released. The fixed band spring 20 then returns to its original position. The movable fixing pin 22 is inserted into the adaptation hole 23 on the rubber band 3 to lock the rubber band 3 into the locking seat 4, thereby binding the protective shell 1 to the wrist. This avoids the phenomenon of carrying the power bank by hand and effectively improves the portability. At the same time, by inserting the fixing pin 22 into the adaptation hole 23 at different positions on the rubber band 3, it can adapt to wrists of different sizes. By forcefully moving multiple protective shells 1 in the opposite direction, two adjacent protective shells 1 can be brought together. At this time, the shifting post 10 will slide into the shifting hole 9 to the rubber locking block 14. At the same time, the rubber locking block 14 is re-inserted into the triangular locking groove 11 on the shifting post 10 to restrict it, so that multiple protective shells 1 can be transformed into a block shape for easy storage. In this way, the power bank can be flexibly transformed into a ring shape or a block shape to meet different usage needs.
