Description

Technical Field

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

[0002] A multi-functional portable power bank is a portable power device that integrates multiple functions. It expands upon basic charging capabilities, offering features beyond the common USB interface for charging mobile phones, tablets, headphones, and other digital devices. Some models also include an AC output interface, capable of powering laptops, electric kettles, and rice cookers, meeting the power needs of outdoor leisure, mobile office work, and home emergencies. Typically using lithium-ion batteries and dry-cell batteries as energy storage units, they are characterized by large capacity, versatility, long lifespan, and safety and reliability. Internally equipped with a high-performance power management system, they effectively protect the power source and the charged devices. In terms of design, portability is emphasized, making them convenient for users to carry and use during travel, business trips, and outdoor activities. Some models also feature handles and wheels for easy movement. Some products are also waterproof, dustproof, and pressure-resistant to adapt to different usage environments. However, bumps and knocks are inevitable during use, necessitating the use of drop-proof mechanisms.

[0003] Existing drop protection mechanisms consist of drop protection components and support components. The drop protection component is installed on one side of the power bank's main body. A first axle is connected to the inner side of the fixed frame within the drop protection component, and a finger ring is connected to the outer wall of the first axle. The finger ring can rotate out from the fixed frame. When holding the power bank, the user can pass their fingers through the finger ring and then grip the main body, improving grip stability and reducing the probability of the power bank falling due to an unstable grip. Some power banks have support components that can be stored on one side when not in use. When it's necessary to use a phone while charging, the support component can be rotated out to form a triangular support, which not only supports the charging phone but also increases the stability of the power bank when placed, reducing the risk of falling due to accidental collisions. However, this structure still cannot buffer the impact force in the event of a collision or drop, resulting in damage to the power bank and affecting normal use. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multifunctional mobile charging power supply, which aims to improve the problem that the existing anti-drop structure still cannot buffer the impact force when it is collided or dropped, thus causing damage to the mobile power supply and affecting its normal use.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a multifunctional mobile charging power supply, including a housing, with multiple elongated grooves on both the left and right sides of the housing. Multiple fixing rings are fixedly connected to the inner walls of the elongated grooves near the center. A fixing rod is fixedly connected inside each fixing ring. Multiple springs are slidably connected to the upper and lower ends of the outer walls of the fixing rods. A slider is fixedly connected to the side of each spring that is furthest away from the center. A circular hole is formed near the center of the inside of the slider. The inner wall of the circular hole is slidably connected to the outer wall of the fixing rod. A moving rod is fixedly connected near the center of the side of the slider that is furthest away from the center. A cylindrical groove is formed inside the moving rod.

The bottom left and right ends of the housing have multiple circular holes, and the inner wall of each circular hole is slidably connected to the upper end of the outer wall of each locking post.

[0008] As a further description of the above technical solution:

[0009] Multiple fixing blocks are fixedly connected to both the front and rear ends of the fixing ring, and the front side of the fixing block is fixedly connected to the inner wall of the elongated groove.

[0010] As a further description of the above technical solution:

[0011] A cylindrical block is fixedly connected to the lower front end of the housing, and a collar is fixedly connected to the front side of the cylindrical block.

[0012] As a further description of the above technical solution:

[0018] As a further description of the above technical solution:

[0019] The bottom of the housing is provided with multiple charging ports, and the inner wall of the charging port is slidably connected to the outer wall of the buckle.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when the shell falls, the protective shell will push the buffer pad to move closer, at which time the buffer pad will squeeze the sealing ring two. At the same time, the buffer pad will push the moving rod, and then the moving rod will slide closer on the fixed rod. At the same time, the squeezing slider will also move closer, at which time the slider will squeeze the spring one on the fixed rod. At this time, the spring one will be squeezed and deformed, achieving the buffering effect. When the external force disappears, the spring one will return to its original state, and the moving rod will push the protective shell to reset. At this time, the shell can continue to be used, realizing the effect of protecting the shell through the buffering effect of the spring one when the shell falls.

[0022] 2. In this utility model, when not in use, the long sleeve is placed on the charging port. At this time, the buckle on the long sleeve will be locked inside the charging port. At the same time, the long sleeve and the shell will lock the rubber ring inside. The buckle will pass through the long hole, which can reduce the size of the gap. At the same time, the locking post passes through the long sleeve (203) and the rubber ring and is locked inside the circular hole. This realizes the effect of protecting the charging port and preventing water from entering when not in use. Attached Figure Description

At the same time, the buffer pad 16 will push the moving rod 9, and then the moving rod 9 will slide closer on the fixed rod 5. At the same time, the slider 7 will also move closer, and then the slider 7 will compress the spring 6 on the fixed rod 5. The spring 6 will be deformed by the compression, achieving a buffering effect. When the external force disappears, the spring 6 will return to its original state. The spring 6 will then push the slider 7 to move away, and then the slider 7 will push the moving rod 9 to move away. At this time, the moving rod 9 will push the protective shell 17 to reset, and the housing 1 can continue to be used. This achieves the effect of protecting the housing 1 through the buffering effect of the spring 6 even when the housing 1 falls.

[0040] When not in use, the long sleeve 203 is attached to the charging port 18. At this time, the buckle 204 on the long sleeve 203 will be locked inside the charging port 18. At the same time, the long sleeve 203 and the housing 1 will hold the rubber ring 205 inside. The buckle 204 will pass through the long hole 206, which can reduce the size of the gap. Meanwhile, the locking post 202 passes through the long sleeve 203 and the rubber ring 205 and is locked inside the circular hole 201. This achieves the effect of protecting the charging port 18 from water ingress when not in use.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
