Description

Technical Field

[0001] This utility model relates to the field of mobile power technology, and in particular to a mobile power supply with a removable battery. Background Technology

[0002] In today's digital age, mobile electronic devices such as smartphones, tablets, and smartwatches have become an indispensable part of people's lives. These devices are becoming increasingly powerful, but battery life has always been a key factor restricting their use. In order to meet users' needs for continuous power supply to their devices in different scenarios, portable power banks have emerged and quickly gained an important position in the market.

[0003] Traditional power banks mostly use a built-in, non-removable battery design. While this ensures the compactness and stability of the power bank structure to a certain extent, it also has many drawbacks. When the built-in battery reaches the end of its lifespan or malfunctions, users cannot replace the battery themselves and can only scrap the entire power bank or send it to a professional repair shop for repair. This not only increases the cost of use but also wastes resources. For users who often need to go out for long periods of time or are in environments without power supply, once the power bank runs out of power, it is impossible to replenish the power in time, making it difficult to meet their continuous power needs.

[0004] To overcome the above problems, power banks with removable batteries have gradually attracted market attention. However, existing power banks with removable batteries still have some shortcomings in structural design. For example, the battery removal and installation process of some products is relatively complicated and requires the use of professional tools, which brings inconvenience to users.

[0005] Therefore, developing a simple, easy-to-operate, and securely connected detachable battery power bank is of great significance for improving user experience and meeting market demands. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a portable power source with a removable battery.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A portable power bank with a removable battery includes a mounting shell containing a built-in battery assembly. A bottom cover is mounted on the bottom of the mounting shell via a disassembly assembly. A positioning hole is integrally formed on the top of the bottom cover. The disassembly assembly includes a plug rod, a connecting plate, and a fixing plate. The fixing plate is welded to the outer wall of the top of the bottom cover. The plug rod is movably connected to the inner wall of a through hole on the surface of the fixing plate. The connecting plate is fixed to one end of the plug rod. A spring is sleeved on the outer wall of the plug rod, and the two ends of the spring are respectively fixed to the side wall of the connecting plate and the side wall of the fixing plate. Fixing blocks are integrally formed on both inner walls of the mounting shell, and slots for cooperating with the plug rod are formed inside the fixing blocks.

[0009] As a further improvement of this utility model: the bottom of the connecting plate is integrally formed with a connecting plate, and the bottom of the connecting plate is integrally formed with a toggle block.

[0010] As a further embodiment of this utility model: the bottom of the cover is threaded with a threaded post, a cylindrical limiting block is welded to the bottom of the threaded post, and a knob is welded to the bottom of the cylindrical limiting block.

[0011] As a further embodiment of this utility model: the battery assembly includes a battery box, a pad, and a battery body. The battery box is fixed to the inner wall of the mounting shell, the pad is fixed to the inner wall of the top of the battery box, and the battery body is installed inside the battery box. Conductive module one and conductive module two are respectively installed on the inner walls of both sides of the battery box.

[0012] As a further improvement of this utility model: a support plate is welded to the top outer wall of the bottom cover, and a limit frame is welded to the side wall of the support plate.

[0013] As a further improvement of this utility model, a partition is fixed to the bottom outer wall of the pad.

[0014] As a further improvement of this utility model: a charging component is installed on the top of the battery box, and the charging component and the battery body are electrically connected.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] A portable power bank with a removable battery, such as Figures 1 to 7As shown, the mounting housing 1 includes a built-in battery assembly. A bottom cover 2 is installed on the bottom of the mounting housing 1 via a disassembly assembly. A positioning hole 9 is integrally formed on the top of the bottom cover 2. The disassembly assembly includes a rod 16, a connecting plate 19, and a fixing plate 18. The fixing plate 18 is welded to the outer wall of the top of the bottom cover 2. The rod 16 is slidably connected to the inner wall of a through hole on the surface of the fixing plate 18. The connecting plate 19 is fixed to one end of the rod 16. A spring 17 is sleeved on the outer wall of the rod 16, and the two ends of the spring 17 are respectively fixed to the side wall of the connecting plate 19 and the side wall of the fixing plate 18. Fixing blocks 6 are integrally formed on both inner walls of the mounting housing 1, and slots 7 that cooperate with the rod 16 are opened inside the fixing blocks 6.

[0031] When it is necessary to fix the mounting shell 1 and the bottom cover 2, first pull the two sets of connecting plates 19. During this process, the spring 17 is stretched, and the linear distance between the ends of the two insert rods 16 is reduced. Then, the bottom of the mounting shell 1 is placed on the bottom cover 2. The positioning ring 9 is used to position the mounting shell 1 and the bottom cover 2. After the mounting shell 1 and the bottom cover 2 are closed, the insert rod 16 and the slot 7 on the fixing block 6 are in the correct position. Then, after releasing the connecting plate 19, the insert rod 16 is inserted into the slot 7 under the action of the spring 17, thereby fixing the mounting shell 1 and the bottom cover 2.

[0032] The bottom of the connecting plate 19 is integrally formed with a connecting plate 5, and the bottom of the connecting plate 5 is integrally formed with a toggle block 4;

[0033] The toggle block 4 makes it easy to pull the connecting plate 19 with your fingers.

[0034] The bottom cover 2 is threadedly connected to a threaded post 21, and a cylindrical limiting block 20 is welded to the bottom of the threaded post 21. A knob 3 is welded to the bottom of the cylindrical limiting block 20.

[0035] After the insertion rod 16 is inserted into the slot 7, in order to prevent the insertion rod 16 and the slot 7 from being disengaged due to accidental contact with the toggle block 4, the user holds the knob 3 and rotates the threaded post 21 along the threaded hole at the bottom of the bottom cover 2. The toggle block 4 has an arc-shaped notch on its side that matches the outer diameter of the cylindrical limit block 20. The cylindrical limit block 20 fills the arc-shaped notch between the two toggle blocks 4, thus limiting the toggle block 4. That is, the toggle block 4 can neither move forward nor backward, thereby ensuring the stability of the toggle block 4.

[0036] The battery assembly includes a battery box 8, a pad 12, and a battery body 15. The battery box 8 is fixed to the inner wall of the mounting shell 1 by screws, the pad 12 is fixed to the top inner wall of the battery box 8, and the battery body 15 is installed inside the battery box 8. A partition 13 is fixed to the bottom outer wall of the pad 12, and conductive module one 11 and conductive module two 14 are respectively installed on the inner walls of both sides of the battery box 8.

[0037] When it is necessary to install the battery body 15, the battery body 15 is installed between the conductive module 11 and the conductive module 2 14 according to its positive and negative terminals. Both the conductive module 11 and the conductive module 2 14 are provided with conductive contacts that are compatible with the battery body 15. When multiple battery bodies 15 need to be installed, the partition 13 can be used to separate two adjacent battery bodies 15.

[0038] A support plate 22 is welded to the top outer wall of the bottom cover 2, and a limit frame 23 is welded to the side wall of the support plate 22.

[0039] After the battery body 15 is installed and the mounting shell 1 and the bottom cover 2 are fixed, the limiting frame 23 supports and limits the battery body 15, thereby ensuring the stability of the battery body 15 installation.

[0040] A charging assembly 10 is installed on the top of the battery box 8, and the charging assembly 10 and the battery body 15 are electrically connected.

[0041] The charging component 10 includes components such as a circuit board, a charging interface, a display screen, and a control switch. The circuit board, as the core control unit, is electrically connected to the battery body 15 to realize charging and discharging management. The charging interface, such as USB-C or USB-A, is integrated on the top of the circuit board and is used to charge the battery body 15 after connecting to an external power source. The charging interface can charge mobile devices such as mobile phones and tablets. The working principle of the charging component 10 is existing technology and will not be described in detail here.

[0042] Working principle: When an external power source is connected through the charging interface, the circuit board inside the charging assembly 10 activates the charging management function, performing voltage regulation, overcurrent protection, and charging / discharging state switching on the input current. Then, it safely delivers the current to the battery body 15 for energy storage. During discharge, the positive and negative terminals of the battery body 15 form a conductive circuit with the external device through the conductive contacts of conductive module one 11 and conductive module two 14 to achieve power output. When disassembling or assembling the battery body 15, the user pulls the connecting plate 19 laterally using the toggle block 4, causing the insertion rod 16 to slide along the fixing plate 18 and pull... When the insertion rod 16 is completely disengaged from the slot 7 of the fixing block 6 inside the mounting housing 1, the bottom cover 2 separates from the mounting housing 1, and the battery assembly can be removed as a whole for replacement. During installation, the bottom cover 2 is aligned with the mounting housing 1 and pressed down. The positioning ring 9 ensures that the two are precisely aligned. After releasing the toggle block 4, the spring 17 pushes the insertion rod 16 into the slot 7 automatically through the rebound force. Finally, the knob 3 is rotated to drive the threaded column 21 to rotate, so that the cylindrical limit block 20 moves into the arc-shaped notch on the side of the toggle block 4 to form a mechanical locking structure, which effectively prevents accidental contact that could cause the bottom cover 2 to loosen.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
