Description

Technical Field

[0001] This utility model relates to the field of portable electronic device charging technology, and in particular to a wired mobile power supply. Background Technology

[0002] With the widespread use of portable electronic devices such as smartphones and tablets, the market demand for power banks, as an important accessory, continues to grow. Currently, power banks on the market are mainly divided into two types: those with built-in charging cables and those with external charging cables. While power banks with built-in charging cables are convenient, the charging cable length is fixed and cannot be replaced, resulting in poor flexibility. Power banks with external charging cables require users to carry an extra charging cable, which is easy to lose and inconvenient to use. In addition, existing power banks pose a risk of overheating when used in high-temperature environments, affecting charging efficiency and device safety. In recent years, consumers have placed higher demands on the portability, multifunctionality, and safety of power banks, creating an urgent need for a highly integrated, multifunctional, and reliable power bank solution.

[0003] A corded power bank mainly consists of a shell, a storage battery, a circuit board, a built-in charging cable, a storage structure, and a power indicator light. The shell is usually made of fire-retardant ABS or PC material to protect the internal components. The storage battery is generally a lithium-ion battery pack that provides energy reserves. The circuit board integrates a charge and discharge management chip and protection circuitry to control energy input and output and ensure safety. The built-in charging cable usually includes common interfaces such as USB-C and Lightning, allowing direct connection to devices for charging. The cable storage structure is designed with a slot or coil to avoid cable tangling. The power indicator light displays the remaining power through an LED light group for easy viewing by the user.

[0004] In existing technologies, some corded power banks lack convenient placement stands, resulting in inconvenience. During charging, the device can only be placed haphazardly, easily sliding on the table, causing the charging port to loosen and break, or even damaging the device. Users often have to hold the power bank and the device, and the combined weight and dragging of the cable can easily cause wrist pain. When placed flat on the table, the power indicator light is obstructed, making it difficult to see the remaining power. Furthermore, the corded design, intended for portability, requires additional support tools due to the lack of a stand, and the tangled cable interferes with device placement, actually reducing ease of use. Therefore, a corded power bank is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a corded portable power bank, which aims to improve the problem that some corded portable power banks in the prior art lack a convenient stand design, resulting in equipment damage and reduced ease of use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A corded power bank includes a protective shell 1, a protective shell 2 fixedly connected to the inner wall of the protective shell 1, a support mechanism installed inside the protective shell 2, a fixing frame fixedly connected to the inner wall of the protective shell 1, and a replacement mechanism installed outside the fixing frame. The support mechanism includes a sliding shell, the outer wall of which is fixedly connected to the inner wall of the second protective shell, a sliding disk slidably connected to the inner wall of the sliding shell, a sliding column fixedly connected to the inner wall of the sliding disk, a button fixedly connected to the bottom end of the sliding column, a limiting shell fixedly connected to the inner wall of the second protective shell, a spring sleeved on the outside of the sliding column, a connecting plate fixedly connected to the outer wall of the sliding disk, a limiting frame fixedly connected to the outer wall of the connecting plate, and a storage component provided inside the second protective shell. Through the above technical solution: the first protective shell serves as the outer layer of protection, while the second protective shell, whose inner wall is fixed, is used to divide the space and install the support mechanism. The support mechanism allows the support plate to unfold and form a stable support structure. The sliding plate is connected to the first button via the sliding column, and the first spring provides the reset capability. The connecting plate drives the limit frame to control the storage component, realizing the expansion and contraction of the bracket and facilitating the placement of the equipment.

[0007] Preferably, the storage assembly includes a storage shell, the outer wall of which is fixedly connected to the inner wall of the second protective shell, a first support plate is rotatably connected to the inner wall of the storage shell, a limit buckle is fixedly connected to the outer wall of the first support plate, a second support plate is rotatably connected to the outer wall of the first support plate, and a plurality of limit blocks are fixedly connected to the inner wall of the storage shell. Through the above technical solution: the storage component consists of a storage shell fixed to the inner wall of the second protective shell, two rotatably connected support plates, a limiting buckle and a limiting block. The storage shell provides storage space and a fulcrum for rotation. The first support plate drives the second support plate to unfold to form a triangular support structure and is fixed by the limiting block. When stored, the limiting buckle and the limiting frame engage and lock.

[0008] Preferably, the replacement mechanism includes a sealing ring, the outer wall of which is detachably connected to the inner wall of the fixed frame. Two fixed posts are fixedly connected to the outer wall of the fixed frame. A sliding ring is slidably connected to the outer wall of the fixed posts. A rotating arm is rotatably connected to the outer wall of the sliding ring. A rotating arm is rotatably connected to the other end of the rotating arm. A sliding ring is rotatably connected to the other end of the rotating arm. A connecting ring is fixedly connected to the top of the sliding ring. A button is fixedly connected to the top of the connecting ring. A spring is sleeved on the outside of the fixed posts. The above technical solution involves installing the sealing ring through a fixed frame in the replacement mechanism. The sliding rings one and two slide with the support of the fixed column. When button two is pressed, the connecting ring drives the sliding ring two to slide down and compress the spring two. The rotating arms one and two work together to push the sliding ring one out of the sealing ring. After being released, the spring two returns to its original position, and the sliding ring one clamps the sealing ring to achieve a seal.

[0009] Preferably, the inner wall of the second sliding ring is slidably connected to the outer wall of the fixed column, and the inner wall of the connecting ring is slidably connected to the outer wall of the fixed column; With the above technical solution: both the sliding ring 2 and the connecting ring slide along the outer wall of the fixed column. The replacement operation of the sealing ring is realized by transmitting the pressing pressure. When the button 2 is pressed, the connecting ring drives the sliding ring 2 to slide down along the fixed column, providing a displacement fulcrum for the rotating arm structure to push out the sealing ring. After being released, it is reset by the guide of the fixed column, ensuring accurate positioning and tight fixation of the sealing ring during installation.

[0010] Preferably, one end of the second spring is fixedly connected to the outer wall of the second sliding ring, and the other end of the second spring is fixedly connected to the outer wall of the first sliding ring. Through the above technical solution: the two ends of the spring are fixed to the outer walls of the sliding ring 2 and the sliding ring 1 respectively. Energy is stored and released through elastic deformation. When the button 2 is pressed, the spring is compressed as the sliding ring 2 slides down. After being released, the spring force pushes the sliding ring 2 back to its original position, while simultaneously moving the sliding ring 1. This realizes the ejection and replacement of the sealing ring and its clamping and fixing, ensuring the stability of the sealing structure.

[0011] Preferably, the outer walls of both sliding rings are detachably connected to the outer wall of the sealing ring, and the outer walls of both sliding rings are slidably connected to the inner wall of the fixed frame; The above technical solution involves two sliding rings whose outer walls are detachably connected to the sealing ring, facilitating the removal of the old sealing ring and the installation of the new sealing ring. At the same time, their outer walls slide within the inner wall of the fixed frame, providing guidance for the sealing ring to be ejected or fixed, ensuring that the sealing ring moves along a fixed trajectory, avoiding deviation, and achieving convenient replacement and stable installation of the sealing ring.

[0012] Preferably, one end of the first spring is fixedly connected to the inner wall of the sliding shell, and the other end of the first spring is fixedly connected to the outer wall of the sliding disk; Through the above technical solution: the two ends of the spring are fixed to the inner wall of the sliding shell and the outer wall of the sliding disk respectively. Energy is stored and released through elastic deformation. When the button is pressed, the spring is compressed. After it is released, the spring force pushes the sliding disk down to reset, which drives the limit frame and the limit buckle to engage, thereby locking the storage component and ensuring the stable fixation of the support structure after it is retracted.

[0013] Preferably, the outer wall of the second support plate is detachably connected to the outer wall of the limiting block, the outer wall of the first button is slidably connected to the inner wall of the limiting shell, and the outer wall of the limiting buckle is detachably connected to the outer wall of the limiting frame.

[0014] Through the above technical solution: the second support plate and the limiting block can be detachably engaged, forming a stable support structure when unfolded, and detached for folding when stored. The first button slides on the inner wall of the limiting shell, and the limiting shell restricts the sliding direction to ensure that the pressing pressure is accurately transmitted to the sliding column. The limiting buckle and the limiting frame can be detachably engaged to realize the locking and unlocking control of the storage components. The three work together to ensure that the support structure is convenient and stable to unfold.

[0015] This utility model has the following beneficial effects: 1. In this utility model, the pressing operation of the button drives the sliding plate, connecting plate and limiting frame and other components to release the locking of the storage component, so that the support plate unfolds to form a support structure, thereby achieving the effect of convenient placement of electronic devices by users, improving the problems of loose interface and sliding caused by random placement of the device during charging, increasing the product's usage scenarios and meeting the user's needs in different environments.

[0016] 2. In this utility model, with the cooperation of structures such as the fixed column, sliding ring, rotating arm and spring, the sealing ring can be easily ejected or fixed, thereby improving the problem of inconvenient replacement of traditional sealing rings, facilitating the maintenance of the sealing performance of the power bank, and preventing dust and moisture from entering the interior and affecting circuit safety.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1 , Figure 2 and Figure 5 This utility model provides an embodiment of a corded power bank, including a protective shell 1. The protective shell 1 serves as the outermost protective structure of the power bank and is made of fire-resistant ABS or PC material, possessing drop resistance, wear resistance, and heat insulation properties. It provides an installation base for the support mechanism 3 and the replacement mechanism 5. A protective shell 2 is fixedly connected to the inner wall of the protective shell 1. The protective shell 2 is used to separate the internal space, separating the support mechanism 3 from the power supply, thereby improving safety. The support mechanism 3 is installed inside the protective shell 2. By pressing the button 34, the sliding plate 32, the connecting plate 37, and the limiting frame 38 are activated, releasing the lock on the storage component 39. This allows the support plate 392 and the support plate 394 to unfold and form a support structure, facilitating the placement of electronic devices by the user. A fixing frame 4 is fixedly connected to the inner wall of the protective shell 1, providing installation positioning for the sealing ring 51 to achieve a sealing effect. The replacement mechanism 5 is installed outside the fixing frame 4 to facilitate the convenient replacement of the sealing ring 51. Specifically, the protective shell 1 provides an installation base for the support mechanism 3 and the replacement mechanism 5, and works with the protective shell 2 to separate the internal space to improve safety. The support mechanism 3 uses the button 1 34 to link with the sliding disk 32 and other components to unfold the storage component 39 to form a device support structure. The fixed frame 4 works with the replacement mechanism 5 to achieve the sealing positioning and convenient replacement of the sealing ring 51. Through the coordinated design of layered protection, space separation, support linkage and sealing maintenance, the protection safety, ease of use and maintenance of the power bank are improved.

[0021] Support mechanism 3 includes a sliding shell 31, which ensures the stability of the sliding disc 32 during sliding, preventing deviation or jamming. The outer wall of the sliding shell 31 is fixedly connected to the inner wall of the second protective shell 2, which provides a stable mounting point for the sliding shell 31. The sliding disc 32 is slidably connected to the inner wall of the sliding shell 31. When the sliding disc 32 moves upward, it causes the limiting frame 38 to disengage from the limiting buckle 393. After releasing the button, it resets under the action of the first spring 36, realizing the locking and unlocking control of the storage component 39. A sliding post 33 is fixedly connected to the inner wall of the movable plate 32. The sliding post 33 transmits the pressing pressure of the button 34 to the sliding plate 32. At the same time, with the cooperation of the spring 36, it guides the sliding plate 32 to slide precisely in the vertical direction. The bottom end of the sliding post 33 is fixedly connected to the button 34. When the user presses the button 34, it triggers the unlocking action of the support mechanism 3, allowing the support plate of the storage component 39 to unfold. After being released, it returns to its original position under the action of the spring 36, maintaining the locked state of the support mechanism 3 for easy user operation. A limiting shell 35 is fixedly connected to the inner wall of the sliding shell 31. The limiting shell 35 prevents the button 34 from shaking or shifting during sliding, ensuring that the pressing force is accurately transmitted to the sliding column 33. A spring 36 is sleeved on the outside of the sliding column 33. When the button 34 is pressed, the spring 36 is compressed and stores elastic potential energy. After the button is released, the spring releases the potential energy and pushes the sliding plate 32 to move down and reset. A connecting plate 37 is fixedly connected to the outer wall of the sliding plate 32. When the sliding plate 32 slides up and down in the sliding shell 31, the connecting plate 37 drives the limiting shell 32 to move down and reset. The frame 38 moves synchronously, so that the limiting frame 38 can accurately engage or disengage with the limiting buckle 393, thereby achieving locking control of the storage component 39. The outer wall of the connecting plate 37 is fixedly connected to the limiting frame 38. When the limiting frame 38 moves up with the sliding plate 32, it disengages from the limiting buckle 393 and unlocks the storage component 39. When it moves down, it engages with the limiting buckle 393 and locks the storage component 39, preventing the support plate from shaking in the storage state. The storage component 39 is provided inside the second protective shell 2. The storage component 39 is used to store and unfold the support bracket. Specifically, the support mechanism 3 consists of a sliding shell 31 fixed to the inner wall of the protective shell 2, a sliding disc 32 connected to the sliding column 33, a spring 36 sleeved on the outside of the sliding column 33, a connecting plate 37 connecting the sliding disc 32 and the limiting frame 38, and a storage component 39 containing a limiting buckle 393. The components work together through mechanical linkage and elastic reset mechanism. When the button 34 is pressed, the sliding column 33 drives the sliding disc 32 to move upward in the sliding shell 31. The connecting plate 37 causes the limiting frame 38 to disengage from the limiting buckle 393, unlocking the storage component 39 to unfold the support plate. After the button is released, the spring 36 pushes the sliding disc 32 to reset, and the limiting frame 38 re-engages with the limiting buckle 393 to lock the bracket, realizing convenient unfolding and stable fixation of the support structure and improving the placement problem when charging the equipment.

[0022] Reference Figures 2 to 4The storage component 39 includes a storage shell 391, which provides storage space and a rotation fulcrum for support plate 1 392 and support plate 2 394. The outer wall of the storage shell 391 is fixedly connected to the inner wall of the protective shell 2 2, which provides stable installation for the storage shell 391. The inner wall of the storage shell 391 is rotatably connected to support plate 1 392. When unfolded, support plate 1 392 first rotates and extends around the storage shell 391, providing a support base for the unfolding of support plate 2 394. When stored, it drives support plate 2 394 to retract into the storage shell 391 together, and is fixed by engaging with limit buckle 393 and limit frame 38. The outer wall of support plate 1 392 is fixedly connected to limit buckle 393. When support plate 1 392 is retracted into storage... When the housing 391 is in use, the limiting buckle 393 engages with the slot of the limiting frame 38 through its own deformation, thereby locking the storage component 39 and preventing the support plate from accidentally unfolding during the use of the power bank. The outer wall of the first support plate 392 is rotatably connected to the second support plate 394. After the second support plate 394 is unfolded around the first support plate 392, it forms a stable triangular support structure with the first support plate 392 and the limiting block 395. The inner wall of the storage housing 391 is fixedly connected to multiple limiting blocks 395. When the second support plate 394 is rotated to engage with the limiting block 395, the position of the second support plate 394 can be fixed, so that the support structure remains in a stable unfolded state, preventing the second support plate 394 from rotating randomly due to the weight of the equipment, and ensuring the support effect. Specifically, the storage component 39 consists of a storage shell 391 fixed to the inner wall of the second protective shell 2, a support plate 392 rotatably connected to the storage shell 391, a support plate 394 rotatably connected to the support plate 392, a limiting buckle 393 fixed to the outer wall of the support plate 392, and a limiting block 395 fixed to the inner wall of the storage shell 391. When stored, the support plate 392 drives the support plate 394 to retract into the storage shell 391 around the pivot point. The limiting buckle 393 on the outer wall of the support plate 392 locks itself in place by deforming and engaging with the slot of the limiting frame 38 to prevent the bracket from accidentally unfolding. When unfolded, the support plate 392 first rotates around the storage shell 391 to form a basic support, and the support plate 394 then rotates around the support plate 392 until it engages with the limiting block 395. Through the spatial storage design of the storage shell 391 and the dual engaging mechanism of the limiting buckle 393 and the limiting block 395, the compact storage and stable unfolding of the support structure are achieved.

[0023] Reference Figures 5 to 7The replacement mechanism 5 includes a sealing ring 51, which seals the charging cable interface. The outer wall of the sealing ring 51 is detachably connected to the inner wall of the fixing frame 4, which determines the installation position of the sealing ring 51. Two fixing posts 52 are fixedly connected to the outer wall of the fixing frame 4. The fixing posts 52 ensure that the sliding ring 1 53 and the sliding ring 2 56 remain stable during sliding. The outer wall of the fixing post 52 is slidably connected to the sliding ring 1 53. When the sliding ring 1 53 slides on the fixing post 52, it can drive the sealing ring 51 to move, thereby ejecting or fixing the sealing ring 51. The outer wall of the sliding ring 1 53 is rotatably connected to the rotating arm 1 54, which transmits the sliding force of the sliding ring 2 56. The other end of the rotating arm 1 54 is rotatably connected to the rotating arm 2 55. The linkage between the rotating arm 2 55 and the rotating arm 1 54 effectively disperses the stress transmitted from the button 2 58, extending the service life of the replacement mechanism 5. The other end of the rotating arm 2 55 rotates... A sliding ring 56 is connected. When button 58 is pressed, the sliding ring 56 slides downward along the fixed post 52, compressing the spring 59. The spring 59 is pushed to move by rotating arm 55 and rotating arm 54. After the button is released, the sliding ring 56 is reset under the action of spring 59, causing the sliding ring 53 to move in the opposite direction, thus realizing the action cycle of the replacement mechanism 5. A connecting ring 57 is fixedly connected to the top of the sliding ring 56. When the connecting ring 57 slides on the fixed post 52, it maintains the synchronization between button 58 and sliding ring 56, ensuring the consistency of the action of the replacement mechanism 5. Button 58 is fixedly connected to the top of the connecting ring 57. The user triggers the action of the replacement mechanism 5 by pressing button 58. Spring 59 is sleeved on the outside of the fixed post 52. When button 58 is pressed, spring 59 is compressed and stores elastic potential energy. After the sealing ring 51 is installed, button 58 is released, and the spring releases its potential energy to push the sliding ring 56 to slide upward along the fixed post 52 to reset. Specifically, the replacement mechanism 5 consists of a sealing ring 51, a fixed frame 4, two fixed posts 52, a sliding ring 53, a rotating arm 54, a rotating arm 55, a sliding ring 56, a connecting ring 57, a button 58, and a spring 59. When the button 58 is pressed, the connecting ring 57 drives the sliding ring 56 to slide down along the fixed post 52, compressing the spring 59. At the same time, the rotating arm 55 and the rotating arm 54 work together to push the sliding ring 53 to slide on the inner wall of the fixed frame 4, pushing out the sealing ring 51. After the button is released, the spring 59 releases its potential energy to push the sliding ring 56 back to its original position. With the guiding support of the fixed post 52, the force transmission of the rotating arm, and the elastic return of the spring, the problem of inconvenient replacement of the traditional sealing ring 51 is improved, and the sealing performance of the device is enhanced.

[0024] Reference Figure 3 , Figure 6 and Figure 7The inner wall of sliding ring 56 is slidably connected to the outer wall of fixed post 52. Sliding ring 56 can slide up and down along the outer wall of fixed post 52, providing a fulcrum for rotating arm 55. When button 58 is pressed, the displacement of sliding ring 56 drives rotating arm 54 to rotate arm 55. The inner wall of connecting ring 57 is slidably connected to the outer wall of fixed post 52. Connecting ring 57 slides along fixed post 52, transmitting the pressing force of button 58 to sliding ring 56, ensuring a smooth force transmission path. One end of spring 59 is fixedly connected to the outer wall of sliding ring 56. The other end of spring 59 is fixedly connected to the outer wall of sliding ring 53. Spring 59 stores and releases energy through elastic deformation. When sliding ring 56 slides, it compresses the spring. After releasing, the spring pushes sliding ring 56 back to its original position, and at the same time drives sliding ring 53 to move. The outer walls of both sliding rings 53 can be detachably connected to the outer wall of sealing ring 51. The detachable connection between sliding ring 53 and sealing ring 51 facilitates the removal of the old sealing ring 51 or the installation of the new sealing ring 51, meeting maintenance and replacement needs. The outer walls of both sliding rings 53 are slidably connected to the inner wall of the fixed frame 4. The inner wall of the fixed frame 4 slides to ensure that the sealing ring 51 moves along a fixed trajectory during ejection or installation, avoiding displacement. One end of the spring 36 is fixedly connected to the inner wall of the sliding shell 31, and the other end of the spring 36 is fixedly connected to the outer wall of the sliding disk 32. The spring 36 pushes the sliding disk 32 to reset through elastic force. When the button 34 is pressed, the spring releases potential energy, causing the sliding disk 32 to move downward, driving the limiting frame 38 to relock the storage component 39. The outer wall of the second support plate 394 is detachably connected to the outer wall of the limiting block 395, and the second support plate 394 and the limiting block 395 are detachably engaged. When unfolded, it engages to form a stable support structure. When stored, it disengages from the limiting block 395 to allow folding. The outer wall of button 34 is slidably connected to the inner wall of the limiting shell 35. The limiting shell 35 provides a sliding track for button 34, restricting its sliding direction and ensuring that the pressing pressure is accurately transmitted to the sliding column 33 to prevent the button from shaking. The outer wall of the limiting buckle 393 is detachably connected to the outer wall of the limiting frame 38. When the limiting buckle 393 engages with the limiting frame 38, it locks the storage component 39 to prevent the support plate from unfolding accidentally. When disengaged, it unlocks, allowing the support plate to unfold or be stored, thus realizing the locking and unlocking control of the support structure. Specifically, sliding ring 56 and connecting ring 57 slide along fixed post 52 to transmit pressing pressure. When button 58 is pressed, sliding ring 56 slides down to compress spring 59. Through the linkage of rotating arm 54 and rotating arm 55, sliding ring 53 slides on the inner wall of fixed frame 4 to push out sealing ring 51. After release, spring 59 returns to its original position, causing sliding ring 53 to clamp sealing ring 51 to achieve sealing. Spring 36 is fixed at both ends to sliding shell 31 and sliding disk 32 respectively. Pressing button 34 compresses spring. After release, sliding disk 32 is pushed through connecting plate 37 to engage with limit frame 38 and limit buckle 393 to lock storage component 39. Support plate 394 engages with limit block 395 to form a support structure. When stored, it is folded away. Button 34 slides inside limit shell 35 to ensure pressing pressure transmission. Limit buckle 393 engages or disengages with limit frame 38 to lock and unlock storage component 39.

[0025] Working principle: When the user needs to use the bracket, he presses button 34 with his finger. This button is fixedly connected to the sliding plate 32 through the sliding column 33. The pressing force is transmitted to the sliding plate 32 through the sliding column 33, causing it to slide upward inside the sliding shell 31. At this time, the spring 36, which is sleeved outside the sliding column 33, is compressed upward and stores elastic potential energy. The sliding plate 32 drives the limiting frame 38 to move upward synchronously through the connecting plate 37. The limiting buckle 393 deforms itself, causing the limiting frame 38 to disengage from the limiting buckle 393 and releasing the lock on the storage component 39.

[0026] After the support plate 392 and support plate 394 inside the housing 391 lose their limiting position, they unfold outward around the rotation fulcrum of the inner wall of the housing 391. Support plate 392 rotates out of the housing 391 first, and then support plate 394 rotates around support plate 392. When the outer wall of support plate 394 engages with the limiting block 395 on the inner wall of the housing 391, a stable triangular support structure is formed, on which the equipment can be leaned. After releasing button 34, spring 36 releases potential energy to push sliding disk 32 downward. Sliding disk 32 drives sliding column 33 to move downward synchronously. Button 34 completes the reset operation, and connecting plate 37 and limiting frame 38 complete the reset operation.

[0027] When storing the support bracket, first manually detach the second support plate 394 from the limiting block 395, rotate and fold it around the first support plate 392 so that it fits against the outer wall of the first support plate 392. Then rotate the first support plate 392 and put it and the folded second support plate 394 into the storage shell 391. During this process, the limiting buckle 393 on the outer wall of the first support plate 392 slides along the outer wall of the limiting frame 38. When the first support plate 392 is completely put into the storage shell 391, the limiting buckle 393 deforms and inserts into the slot of the limiting frame 38.

[0028] When the sealing ring 51 needs to be replaced, press the two buttons 58. The two buttons 58 move towards each other. The pressing force is transmitted through the connecting ring 57. The pressing force causes the sliding ring 56 to slide along the fixed post 52. The two sliding rings 56 slide towards each other, and the spring 59, which is sleeved on the fixed post 52, is compressed. At the same time, the rotating arm 55 and the rotating arm 54 rotate relative to each other. For the replacement mechanism 5 located on the upper side, when the sliding ring 56 moves down, the spring 59 releases its elastic force downward. The angle formed by the rotating arm 54 and the rotating arm 55 becomes smaller. The elastic force released by the rotating arm 54 and the spring 59 together pushes the sliding ring 53 downward. The movement of the two sliding rings 53 pushes the sealing ring 51 out, and the sealing ring 51 can be replaced at this time.

[0029] Align the new sealing ring 51 with the slot on the inner wall of the fixed frame 4 and insert it, ensuring that the edge of the sealing ring 51 is completely in contact with the inner wall of the fixed frame 4. Then release the pressed button 58, the spring 59 releases its compressive potential energy, and pushes the sliding ring 56 to slide outward along the fixed post 52 to reset. The angle between the rotating arm 54 and the rotating arm 55 increases, causing the sliding ring 53 to slide inward and tightly clamp the outer wall of the sealing ring 51. At this time, the sliding ring 53 firmly fixes the sealing ring 51 to the inner wall of the fixed frame 4. The elastic material of the sealing ring 51 and the fixed frame 4 form a sealing structure to prevent dust and moisture from entering the inside of the power bank, while ensuring the stability of the charging cable interface after installation.
