Description

Technical Field

[0001] The utility model relates to the technical field of mobile power supplies, in particular to a mobile power supply charging module. Background Art

[0002] In existing mobile power charging technology solutions, ordinary plugs are usually used to electrically connect to sockets. This traditional plug insertion structure relies on mechanical contact, and the plug is inserted into the socket through a simple metal spring or fixed structure to achieve electrical connection. During use, the plug is directly inserted into the corresponding jack for connection, and a certain amount of external force needs to be applied when unplugging. Although this method can basically meet general charging needs, it has certain limitations in terms of stability and ease of plugging and unplugging. For example, the common plug-in and unplugging method cannot effectively prevent loosening, and lacks an effective positioning structure during the insertion process, resulting in a poor operating experience when inserting or unplugging.

[0003] The traditional plug-and-socket connection method has the following drawbacks: First, due to the lack of a precise alignment structure for the insertion process, users are prone to misalignment during insertion, resulting in poor connection and unstable charging. Second, the connection between the plug and the socket relies on physical friction. If the dimensions of the plug and the socket are not precisely matched, the plug can easily become loose, causing poor electrical contact. During use, this looseness can affect charging stability and even cause safety hazards such as arcing or short circuits. In addition, when plugging and unplugging a traditional plug, the user needs to apply a large external force to operate, which is not user-friendly for frequent users, and the spring clip is prone to failure due to repeated bending, reducing the product's service life. The traditional structure has limited locking capacity and cannot effectively prevent the connection from falling off due to accidental pulling, which affects the safety and stability of the device. In view of this, research and improvements are conducted to address the existing problems, and a mobile power charging module is provided to solve the current problems. The purpose is to achieve the purpose of solving the problems and improving the practical value through this technology. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0023] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0024] The following is combined with Figure 1-Figure 5 A mobile power charging module is described according to some embodiments of the present invention.

[0025] Example 1

[0026] This embodiment provides a mobile power charging module, including: a charging plug 100 and a mobile power module 200, and a connection plate 120 and an alignment plate 210 fixed to the surfaces of the charging plug 100 and the mobile power module 200 respectively. The surface of the charging plug 100 is provided with an alignment groove 110 that is compatible with the mobile power module 200. The surfaces of the connecting plate 120 and the alignment plate 210 are respectively provided with a first stop 140 and a second stop 220 arranged in a one-to-one correspondence. The surface of the connecting plate 120 is fixedly mounted with a plug ear 130, and one end of the plug ear 130 is provided with a locking ball head 131. The surface of the alignment plate 210 is provided with a socket 211 that is compatible with the plug ear 130 and the locking ball head 131. A slide groove 212 is fixedly mounted on one side of the alignment plate 210, and a locking sleeve block 230 is slidably mounted on the inner side of the slide groove 212. One end of the slide groove 212 is fixedly connected to a spring piece 231 fixedly connected to the end of the locking sleeve block 230. The surface of the locking sleeve block 230 is provided with a socket hole 232 and a locking slot hole 233.

[0027] In this embodiment, the interaction between the charging plug 100 and the mobile power module 200 enables quick plugging and a secure connection during charging. When connecting the charging plug 100 to the mobile power module 200, the user aligns the plug lug 130 and locking ball 131 with the socket 211 and the socket hole 232. During insertion, the sliding movement of the locking block 230 and the elastic deformation of the spring 231 allow the locking ball 131 to smoothly pass through the socket hole 232 and lock into place behind the locking slot 233, achieving a stable electrical connection. During charging, current is transferred from the plug lug 130 to the mobile power module 200, ensuring a stable and efficient charging process.

[0028] Example 2

[0029] This embodiment is further optimized based on the first embodiment, and an improvement in the internal structure is added to make the charging process more efficient and safer.

[0030] Inside the charging plug 100, a voltage transformer and a voltage regulator are installed. Their outputs are electrically connected to the ends of the plug ears 130 to ensure stable current and voltage during transmission. The voltage transformer converts input power to a voltage suitable for charging, while the voltage regulator ensures stable output current.

[0031] The input terminals of the plug ears 130 are electrically connected to the charging protection module, which is connected to the electrodes at the input terminals of the mobile power module 200. This module monitors the input current and voltage in real time to prevent abnormalities such as overcharging, overcurrent, or short circuits, thereby improving the safety of the charging process.

[0032] The design of the socket hole 232 and the locking ball 131 are precisely matched, ensuring smooth insertion. The locking slot 233 has a diameter that is equal to that of the plug ear 130 and smaller than the diameter of the locking ball 131, allowing the locking ball 131 to be positioned and stably inserted after insertion, thanks to the locking sleeve block 230.

[0033] The spring piece 231 is an elastic piece structure, which is designed to pull the lock sleeve block 230 to perform elastic movement through the design of the inner side of the slide groove 212. During the insertion and removal process, elastic adjustment is ensured to achieve smooth insertion and release operations.

[0034] In this embodiment, by improving the internal module layout and adding protective structures, the stability of the charging module is improved and the safety of the device during long-term use is enhanced. In actual use, the user simply docks the charging plug 100 and the mobile power module 200 to achieve a fast charging connection. When separation is required, applying a certain amount of pulling force can easily complete the disconnection, without additional complex operations.

[0035] The working principle and use process of this utility model:

[0036] The power bank charging module of the present invention includes a charging plug 100 and a power bank module 200. The charging plug 100 and the power bank module 200 are electrically connected by plugging into each other. During use, the connection plate 120 on the surface of the charging plug 100 is aligned with the alignment plate 210 on the surface of the power bank module 200. The corresponding alignment grooves 110 ensure precise insertion guidance.

[0037] During insertion, the plug ear 130 and locking ball 131 engage with each other to fit into the socket 211 and socket hole 232. Simultaneously, the locking block 230 slides inside the slide slot 212, causing the spring 231 to elastically deform. Once the locking ball 131 is fully inserted into the socket hole 232, the spring 231 returns to its original position, locking the locking block 230 behind the locking slot 233. This creates a stable locking state and ensures the electrical connection between the charging plug 100 and the mobile power module 200.

[0038] Once connected, the voltage transformer and voltage regulator modules within charging plug 100 provide stable current and voltage to mobile power module 200 via plug ears 130 and locking ball 131, ensuring proper charging of the device. During charging, the charging protection module monitors input and output current and voltage to prevent overcharging and short circuits.

[0039] After charging is completed, the user applies a pulling force to separate the charging plug 100 from the mobile power module 200. During the pulling process, due to the strong pulling effect and the spherical guiding effect of the locking ball head 131, the locking sleeve block 230 slides again inside the slide groove 212, so that the locking ball head 131 can be smoothly disengaged from the socket hole 232, thereby disconnecting the device.
