Description

Technical Field

[0001] This utility model relates to the field of chargers, and more particularly to a portable charging device. Background Technology

[0002] A power bank, also known as a portable power bank, is a portable charging device primarily used to provide emergency power to digital products such as smartphones and tablets. Its core components include lithium or polymer batteries, which convert stored electrical energy into the voltage and current required by the device through built-in circuitry. Power banks are typically equipped with USB ports and support fast charging, wireless charging, and other functions, meeting multiple charging needs. They are characterized by their small size, light weight, and portability, making them suitable for travel, business trips, or daily commutes. When using them, care should be taken to avoid high temperatures, humidity, and overcharging and discharging to extend their lifespan. With technological advancements, some high-end power banks also integrate innovative functions such as solar charging and digital power display.

[0003] Operators often use portable charging devices to charge their mobile phones in emergencies. However, while existing portable charging devices have basic charging functions, they are generally only used when the phone's battery is low. This results in prolonged periods of idle time for these devices. Furthermore, existing charging devices lack protection for the charging port, which can easily accumulate dust during long periods of inactivity. In harsher weather conditions, sand or water can also get into the charging port, significantly reducing the lifespan of the charging equipment. Therefore, improvements are needed.

[0004] The purpose of this invention is to provide a portable charging device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable charging device, comprising a portable charging device body, a fixed frame fixedly connected to the top of the portable charging device body, a rotating rod movably sleeved inside the fixed frame, a first handle fixedly connected to the top of the rotating rod, the bottom end of the rotating rod penetrating the fixed frame and extending into the inner cavity of the fixed frame and fixedly connected to a first bevel gear, a second bevel gear meshing with the outer surface of the first bevel gear, a rotating rod fixedly connected to the left side of the second bevel gear, the other end of the rotating rod penetrating the fixed frame and extending to the outside of the fixed frame and fixedly sleeved with a sealing plate, the left side of the sealing plate movably connected to the right side of the portable charging device body, and a charging port opened inside the right side of the portable charging device body.

[0006] As a preferred embodiment of this utility model, a rectangular plate is fixedly connected to the inner cavity of the fixing frame, a movable rod is movably sleeved inside the rectangular plate, a second handle is fixedly connected to the right side of the movable rod, and the other end of the second handle passes through the fixing frame and is movably connected to the inner surface of the fixing frame.

[0007] As a preferred embodiment of this utility model, the left end of the movable rod penetrates through the rectangular plate and extends to the outside of the rectangular plate and is fixedly connected to a locking block. The outer surface of the locking block is engaged with a locking gear, and the inside of the locking gear is fixedly sleeved with the outer surface of the rotating rod.

[0008] As a preferred embodiment of this utility model, a first spring is movably sleeved on the outer surface of the movable rod, the right side of the first spring is fixedly connected to the left side of the second handle, and the left side of the first spring is fixedly connected to the right side of the rectangular plate.

[0009] As a preferred technical solution of this utility model, a rectangular block is fixedly connected to the top of the portable charging device body, a pull rod is movably sleeved inside the right side of the fixed frame, the other end of the pull rod passes through the fixed frame and the rectangular block in sequence and extends into the inner cavity of the fixed frame and is fixedly connected to a moving block, and diagonal rods are hinged to both the front and rear sides of the moving block, a connecting block is hinged to the other end of the diagonal rod, and a connecting rod is fixedly connected to the other end of the connecting block.

[0010] As a preferred embodiment of this utility model, the other end of the connecting rod passes through the fixing frame and extends to the outside of the fixing frame and is fixedly connected to a clamping plate. The bottom of the clamping plate is movably connected to the top of the fixing frame, and a soft pad is fixedly connected to the inner side of the clamping plate.

[0011] As a preferred embodiment of this utility model, a second spring is movably sleeved on the outer surface of the pull rod, the right side of the second spring is fixedly connected to the inner surface of the fixing frame, and the left side of the second spring is fixedly connected to the right side of the rectangular block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a first bevel gear, a second bevel gear, a rotating rod, a sealing plate, and a first handle, firstly pulls the second handle, causing the movable rod to drive the locking block to move to the right, thereby disengaging the locking block from the outer surface of the locking gear and releasing the fixing effect on the locking gear and rotating rod. Then, rotating the first handle causes the rotating rod to drive the first bevel gear to rotate synchronously, which in turn causes the second bevel gear to start rotating. At this time, the second bevel gear will drive the rotating rod and the sealing plate to rotate, ultimately causing the sealing plate to rotate upward and release the sealing effect on the charging port, allowing the operator to use the charging port normally for charging. This ensures that the sealing plate can achieve the sealing effect on the charging port, preventing small amounts of water droplets or dust from entering the charging port and affecting its normal charging function.

[0014] 2. This utility model, by setting up connecting blocks, connecting rods, clamping plates, soft pads, and a second spring, pulls the rod outward. At this time, the moving block overcomes the elastic force of the second spring and moves horizontally to the right under the limiting effect of the rectangular block, thereby causing the two diagonal rods to move. This causes the two connecting blocks to drive the two connecting rods to move horizontally in opposite directions under the limiting effect of the fixed frame. At this time, the two clamping plates drive the two soft pads to move in opposite directions synchronously. When the mobile phone to be charged is placed on the top of the fixed frame and the rod is released, the two clamping plates drive the two soft pads to move horizontally towards each other under the elastic force of the second spring, thereby clamping and fixing the mobile phone and preventing the charging process from being interrupted due to the mobile phone shaking during charging.

Rather, these embodiments are provided to make this utility model more thorough and complete, and to fully convey the scope of this utility model to those skilled in the art.

[0023] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms “a,” “the,” and “the” used in this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0024] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0025] In the description of this utility model, it should be understood that the terms "thickness", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

[0028] like Figures 1 to 5 As shown, this utility model provides a portable charging device, including a portable charging device body 1. A fixed frame 2 is fixedly connected to the top of the portable charging device body 1. A rotating rod 3 is movably sleeved inside the fixed frame 2. A handle 8 is fixedly connected to the top of the rotating rod 3. The bottom end of the rotating rod 3 passes through the fixed frame 2 and extends into the inner cavity of the fixed frame 2, and is fixedly connected to a bevel gear 4. A second bevel gear 5 is meshed with the outer surface of the first bevel gear 4. A rotating rod 6 is fixedly connected to the left side of the second bevel gear 5. The other end of the rotating rod 6 passes through the fixed frame 2 and extends to the outside of the fixed frame 2, and is fixedly sleeved with a sealing plate 7. The left side of the sealing plate 7 is movably connected to the right side of the portable charging device body 1. A charging port 9 is opened inside the right side of the portable charging device body 1.

[0029] When the first handle 8 is rotated, the fixed frame 2 will drive the first bevel gear 4 to rotate synchronously, which in turn will cause the second bevel gear 5 to start rotating. At this time, the second bevel gear 5 will drive the rotating rod 6 and the sealing plate 7 to rotate synchronously, which will eventually cause the sealing plate 7 to release the sealing effect on the charging port 9, so that the operator can use the charging port 9 to charge normally. In this way, the sealing plate 7 can achieve the sealing effect on the charging port 9, preventing a small amount of water droplets or dust from entering the interior of the charging port 9 and affecting the normal charging function of the charging port 9.

[0030] The inner cavity of the fixed frame 2 is fixedly connected to a rectangular plate 10, and a movable rod 11 is movably sleeved inside the rectangular plate 10. A second handle 15 is fixedly connected to the right side of the movable rod 11, and the other end of the second handle 15 passes through the fixed frame 2 and is movably connected to the inner surface of the fixed frame 2.

[0031] When the second handle 15 is pulled, the movable rod 11 will move horizontally to the right under the limiting action of the rectangular plate 10.

[0032] The left end of the movable rod 11 passes through the rectangular plate 10 and extends to the outside of the rectangular plate 10 and is fixedly connected to a locking block 12. The outer surface of the locking block 12 is engaged with a locking gear 13, and the inside of the locking gear 13 is fixedly sleeved with the outer surface of the rotating rod 3.

[0033] When the locking block 12 disengages from the outer surface of the locking gear 13, the fixing effect on the locking gear 13 and the rotating rod 3 will be released.

[0034] Among them, the outer surface of the movable rod 11 is movably sleeved with a first spring 14, the right side of the first spring 14 is fixedly connected to the left side of the second handle 15, and the left side of the first spring 14 is fixedly connected to the right side of the rectangular plate 10.

[0035] Due to the design of the first spring 14, the locking block 12 has a good reset effect during subsequent movement.

[0036] The portable charging device body 1 has a rectangular block 17 fixedly connected to its top. The right side of the mounting frame 2 has a pull rod 16 movably sleeved inside. The other end of the pull rod 16 passes through the mounting frame 2 and the rectangular block 17 in sequence and extends into the inner cavity of the mounting frame 2 and is fixedly connected to a moving block 18. The front and rear sides of the moving block 18 are hinged with diagonal rods 19. The other end of the diagonal rod 19 is hinged to a connecting block 20. The other end of the connecting block 20 is fixedly connected to a connecting rod 21.

[0037] When the lever 16 is pulled, the moving block 18 will move horizontally to the right under the limiting action of the rectangular block 17, thereby causing the two diagonal rods 19 to move, and causing the two connecting blocks 20 to drive the two connecting rods 21 to move in opposite directions.

[0038] The other end of the connecting rod 21 passes through the fixing frame 2 and extends to the outside of the fixing frame 2 and is fixedly connected to a clamping plate 22. The bottom of the clamping plate 22 is movably connected to the top of the fixing frame 2, and a soft pad 23 is fixedly connected to the inner side of the clamping plate 22.

[0039] The design of the soft pad 23 prevents the clamping plate 22 from scratching the surface of the phone during the subsequent clamping process.

[0040] The outer surface of the pull rod 16 is movably sleeved with a second spring 24. The right side of the second spring 24 is fixedly connected to the inner surface of the fixing frame 2, and the left side of the second spring 24 is fixedly connected to the right side of the rectangular block 17.

[0041] Due to the design of the second spring 24, the two soft pads 23 rely on the elasticity of the second spring 24 to clamp the phone, which can fix the phone without applying too much force.

[0042] Working principle and usage process of this utility model:

[0043] When charging is required through charging port 9, first pull handle 15, causing the movable rod 11 to move the locking block 12 to the right. This disengages the locking block 12 from the outer surface of the locking gear 13, releasing the locking effect on the locking gear 13 and the rotating rod 3. Then rotate handle 8, causing the rotating rod 3 to drive the first bevel gear 4 to rotate synchronously. This causes the second bevel gear 5 to start rotating, which in turn drives the rotating rod 6 and the sealing plate 7 to rotate. Ultimately, the sealing plate 7 rotates upward and releases the sealing effect on charging port 9, allowing the operator to use charging port 9 normally. This ensures that the sealing plate 7 can seal the charging port 9, preventing small amounts of water droplets or dust from entering the charging port 9 and affecting its normal charging function.

[0044] During charging using charging port 9, to ensure stability during charging, the phone needs to be secured. Pulling the lever 16 outwards causes the moving block 18 to overcome the elastic force of the second spring 24 and move horizontally to the right under the limiting effect of the rectangular block 17. This causes the two diagonal rods 19 to move, and the two connecting blocks 20 to drive the two connecting rods 21 to move horizontally in opposite directions under the limiting effect of the fixing frame 2. Simultaneously, the two clamping plates 22 drive the two soft pads 23 to move in opposite directions. Placing the phone to be charged on top of the fixing frame 2 and releasing the lever 16 allows the two clamping plates 22 to drive the two soft pads 23 to move horizontally towards each other under the elastic force of the second spring 24, thus clamping and securing the phone and preventing the charging process from being interrupted due to phone movement.
