Description

Technical Field

[0001] The utility model relates to the technical field of charging equipment, in particular to a power bank. Background Art

[0002] Power banks, also known as mobile power banks or portable chargers, are an indispensable electronic accessory in modern life. However, a key issue in the design and production of power banks is the securing method of internal components. Currently, many key components within power banks, such as battery packs and circuit boards, are typically secured to the inside of the outer casing using adhesives. While this securing method simplifies the production process and reduces costs to a certain extent, it has exposed some significant problems over long-term use. During operation, especially during high-power charging or discharging, power banks generate a certain amount of heat. Over time, this continuous heat accumulation causes the glue or adhesive used for securing the components to degrade, significantly reducing their viscosity. As a result, previously securely secured components such as batteries and circuit boards may gradually loosen or even fall off, compromising the normal use of the power bank and potentially causing safety hazards such as short circuits and leakage. Utility Model Content

[0003] In order to overcome the defects of the existing technology, the utility model proposes a power bank that can solve the problem that the internal components of the current power bank are fixed to the outer shell by gluing, which causes the viscosity to decrease due to internal heat during long-term use, and then the components are easily fallen off, affecting the normal use of the product.

[0004] To achieve this purpose, the present invention adopts the following technical solutions:

[0005] The utility model provides a power bank, which includes a shell and several internal components. The internal components are located inside the shell. A bracket is provided inside the shell. The bracket is snap-fitted with the inner side of the shell, and one or more internal components are fixedly connected to the bracket.

[0006] The preferred technical solution of the present invention is that a plurality of grooves are provided on the inner side of the shell, a plurality of protrusions matching the grooves are provided on the outer side of the bracket, and the bracket and the inner side of the shell are snap-fitted through the grooves and the protrusions.

[0007] An optimal technical solution of the present invention is that the grooves are respectively arranged on the four inner side edges of the shell, and the protrusions are respectively arranged on the four outer side edges of the bracket.

[0008] An optimal technical solution of the present invention is that the internal components include a circuit board and a battery, the circuit board and the battery are mounted on a bracket, and the circuit board and the battery are electrically connected.

[0009] An optimal technical solution of the present invention is that the circuit board and the battery are fixedly connected to the bracket respectively, and an adhesive layer is provided between the battery and the bracket.

[0010] An optimal technical solution of the present invention is that the internal components further include a wireless transmitting coil and a magnet ring, and the wireless transmitting coil and the magnet ring are respectively engaged with the bracket.

[0011] An optimal technical solution of the present invention is that the shell consists of an upper shell and a lower shell, and the inner side of the upper shell is snap-fitted with the bracket.

[0012] An optimal technical solution of the present invention is that the material of the shell is transparent material.

[0013] Beneficial effects of the utility model:

[0014] This utility model proposes a power bank that incorporates a bracket structure within the power bank. This bracket and the inner side of the power bank housing utilize a snap-fit ​​design, achieving a secure and removable connection. This facilitates installation and fixation, and key internal components, such as the power supply, are directly fixed to the bracket. This mechanical fixing method not only enhances the connection strength between components but also effectively disperses heat generated during use, reducing the impact of localized overheating on the fixing structure. This effectively avoids the drawback of using traditional adhesives to secure internal components, such as batteries, which suffer from decreased viscosity due to temperature changes. Furthermore, the snap-fit ​​design allows users or maintenance personnel to easily remove and replace internal components without damaging the integrity of the housing, thereby enhancing the product's maintainability and extending its overall service life.

[0024] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0025] Example 1

[0026] like Figure 1-6 As shown, a power bank provided in this embodiment includes a housing 1 and several internal components 2. The internal components 2 are located within the housing 1. A bracket 3 is provided within the housing 1. The bracket 3 snaps into place with the inner side of the housing 1, securely connecting one or more internal components 2 to the bracket 3. The technical solution of this embodiment creatively solves the problem of traditional power bank internal components, such as the power supply, heating up due to long-term use, leading to failure of adhesive fixings, which in turn causes components to fall off and affect normal use of the product. By introducing an innovative bracket structure, the bracket uses a precise snap-fit ​​method to the inner side of the power bank housing, achieving a stable and removable connection and convenient installation and fixation. Key heat-generating components, such as the internal power supply, are directly fixed to the bracket. This mechanical fixing method not only strengthens the connection between components, but also effectively dissipates heat generated during use, reducing the impact of local overheating on the fixing structure, and effectively avoiding the disadvantage of using traditional adhesives to fix internal components such as batteries, which can cause viscosity loss due to temperature changes. In addition, the snap-fit ​​design allows users or maintenance personnel to easily remove and replace internal components without damaging the integrity of the housing, improving the maintainability of the product and extending its overall service life. To sum up, this technical solution fundamentally solves the problem of loose fixation of internal components of the power bank by introducing an innovative design of snap-fitting between the bracket and the shell and fixed connection between the internal components and the bracket, ensuring stable operation and long-term use of the product.

[0027] Preferably, a plurality of grooves 4 are provided on the inner side of the shell 1, and a plurality of protrusions 5 matching the grooves 4 are provided on the outer side of the bracket 3, and the bracket 3 and the inner side of the shell 1 are snap-fitted through the grooves 4 and the protrusions 5. First of all, the snap-fitting design of the grooves and the protrusions in the technical solution of the power bank significantly improves the structural stability and assembly efficiency of the product. Compared with the traditional screw fixing or gluing method, this design does not require additional fasteners, reducing the steps and material costs in the assembly process. At the same time, the snap-fit ​​structure can achieve rapid disassembly and assembly while ensuring stability, facilitates the maintenance and replacement of internal components, and improves the maintainability of the product. Specifically, the grooves 4 and the protrusions 5 both adopt a strip-shaped rectangular structure, which makes the connection more stable, the force is more sufficient, and it is not easy to fall off.

[0028] Preferably, the grooves 4 are respectively arranged on the four sides of the inner side of the shell 1, and the protrusions 5 are respectively arranged on the four sides of the outer side of the bracket 3. Designing the grooves and protrusions on the four inner sides of the shell and the four outer sides of the bracket respectively is a more comprehensive and balanced fixing method. This layout not only ensures the stability of the power bank in the vertical direction, but also strengthens the support in the horizontal direction, so that the power bank can evenly disperse stress when subjected to external force, avoiding damage caused by excessive force on a single point. At the same time, the snap-on design of the four sides increases the contact area, further improving the overall stability and shock resistance. This layout also takes into account the various postures of the power bank during use, such as flat, sideways, etc., and can maintain good stability, avoiding loosening or damage of the internal structure due to changes in posture.

[0029] Preferably, the internal components 2 include a circuit board 21 and a battery 22, which are mounted on a bracket 3 and electrically connected to each other. Specifically, the bracket 3 is provided with latches 31 and holes 32 for securing the battery 21. The latches 31 are symmetrically arranged on the left and right sides. The circuit board 21 is secured to the bracket by means of an inductor 211 on the circuit board 21 and the holes 32. The dimensions of the inductor 211 and the holes 32 match, thus securing the internal components, including the circuit board and battery, to the bracket. Achieving electrical connection through a rational layout is a key element in the power bank's internal design. This design approach ensures a neat and orderly internal structure, facilitates heat dissipation and electromagnetic shielding, and improves the power bank's operating efficiency and stability. Secondly, as a carrier for the internal components, the bracket not only provides a stable mounting base, but also optimizes the connection path between the circuit board and the battery through its structural design, reducing signal interference and energy loss. Furthermore, the bracket's material and strength have been carefully selected, using high-strength, heat-resistant nylon to ensure it can withstand the heat and stress generated during battery charging and discharging, protecting other internal components from damage.

[0030] Preferably, the circuit board 21 and the battery 22 are fixedly connected to the bracket 3 respectively, the circuit board 21 is installed in the lower area of ​​the bracket 3, the charging port 212 of the circuit board 21 extends out of the shell 1, and an adhesive layer is also provided between the battery 22 and the bracket 3. The use of an adhesive layer is a further preferred solution for the power bank, mainly because it significantly improves the stability and safety of the product. First of all, the circuit board and the battery are the core components of the power bank, and their stable connection is the basis for ensuring the normal operation of the power bank. By fixing the two to the bracket respectively, loosening or damage of components caused by vibration or falling can be effectively avoided. In addition, the introduction of an adhesive layer as an additional fixing measure between the battery and the bracket not only further enhances the firmness of the connection, but also absorbs impact energy to a certain extent, protects the battery from direct impact, and prolongs its service life. This dual fixing method ensures that the power bank can maintain stable performance output in various usage environments, improving user experience and product reliability.

[0031] Preferably, the internal component 2 also includes a wireless transmitting coil 23 and a magnetic ring 24, and the wireless transmitting coil 23 and the magnetic ring 24 are respectively engaged with the bracket 3. The integration of the wireless transmitting coil enables the power bank to support wireless charging function. Users do not need to carry an additional charging cable. They only need to bring the device that supports wireless charging close to charge, which greatly facilitates daily use. At the same time, the addition of the magnetic ring, through the engagement with the bracket, not only stabilizes the position of the wireless transmitting coil, but also enables the power bank to be more stably adsorbed on the device that supports magnetic charging, thereby improving the convenience and stability of charging. This design meets the modern demand for wireless and convenient products.

[0032] Preferably, the shell 1 is composed of an upper shell 11 and a lower shell 12, and the inner side of the upper shell 11 is snap-fitted with the bracket 3. The preference of this design scheme lies in the rationality of its structural design and ease of maintenance. By dividing the shell into two parts, an upper shell and a lower shell, and connecting the upper shell to the bracket in a snap-fit ​​manner, not only is the production and assembly process simplified and production efficiency improved, but the disassembly of the shell also becomes simple and quick. When the inside of the power bank needs to be repaired or parts replaced, the user can easily separate the upper and lower shells without destroying the entire shell, which greatly reduces the difficulty and cost of maintenance. In addition, this split design also facilitates personalized customization, such as replacing shells of different colors to meet the diverse aesthetic needs of users.

[0033] Taking into account the magnetic attraction requirements of the power bank, the material used for the shell is not suitable for an all-metal design. Preferably, the material of the shell 1 is a transparent material. The use of transparent materials as the design of the power bank shell not only gives the power bank a unique aesthetic appearance, but also allows users to intuitively see the internal structure and component layout of the power bank, increasing the product's sense of technology and trust. At the same time, the use of transparent materials also promotes the diversity and creativity of the power bank design. Designers can further enhance the product's visual effects and user experience through internal LED lighting effects, color matching, etc. In addition, the transparent shell also helps to dissipate heat, maintain the stability of the internal temperature of the power bank, and extend its service life. The shell material can be made of transparent materials such as acrylic or PC. The above options are easy to process and have good strength and heat resistance.

Those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention.
