Description

Technical Field

[0001] This utility model relates to the field of power adapter technology, specifically a quick-release travel charging adapter. Background Technology

[0002] A travel power adapter is a small, portable power conversion device for electronic devices. Its main function is to convert the power voltage of different countries and regions into a stable voltage required by electronic devices, ensuring that electronic devices can be used normally worldwide and avoiding problems such as device damage or inability to charge due to voltage mismatch. When using a traditional power adapter, disassembly and repair are required when internal faults occur, which necessitates the use of separate tools to completely disassemble the adapter, affecting work efficiency and thus reducing the efficiency of power adapter repair.

[0003] To overcome the aforementioned shortcomings, existing technology (Chinese Patent No. CN222581650U, Publication Date: 2025-03-07) discloses a novel combined power adapter, comprising an adapter body and a three-prong plug. The adapter body has an input port on its side end, and two positioning holes are formed on the side end of the adapter body. Two limiting components are fixedly installed on the side end of the adapter body; wherein the two positioning holes are located on both sides of the input port, and the two limiting components are symmetrically installed; an input cable is fixedly installed on the side end of the three-prong plug, and a shield is provided on the input cable. By designing the input cable of the novel combined power adapter as a snap-fit ​​type, quick and easy replacement of the input cable is possible, thus effectively improving the practicality of the device. Furthermore, the adapter's connector is designed with arc-shaped copper plates for mating, resulting in a tighter connection.

[0004] The aforementioned mechanism allows for the replacement of the input cable using a snap-fit ​​mechanism. However, in actual use, while the power input and output cables can be quickly detached and stored, it is inconvenient to disassemble and repair the external frame of the power adapter body when internal damage occurs. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-release travel charging adapter to solve the problem mentioned in the background art that when a traditional power adapter has an internal fault and needs to be disassembled for repair, it is necessary to use a separate tool to completely disassemble the power adapter, which affects the work efficiency during repair and leads to a decrease in the efficiency of the power adapter during repair.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-release travel charging adapter, comprising an upper mounting bracket, an output interface at the top of the upper mounting bracket, an input interface on the side of the upper mounting bracket, a power switch installed at the top of the upper mounting bracket near the output interface, and an electronic component encapsulation assembly installed on the side inside the upper mounting bracket; a lower mounting bracket is snapped into place at the bottom of the upper mounting bracket, and a quick-release mechanism for quickly disassembling the upper mounting bracket is provided on the side of the top of the lower mounting bracket, the quick-release mechanism including a positioning block, the positioning block being fixedly connected to the top of the lower mounting bracket, and a positioning groove matching the positioning block being provided at the bottom of the upper mounting bracket; a fan is installed on the side of the lower mounting bracket, and a heat dissipation mechanism for assisting the fan in conducting heat is provided on the outer side of the lower mounting bracket.

[0007] Furthermore, the thickness of the positioning block is less than the thickness at the top edge of the lower mounting bracket, and the bottom end of the upper mounting bracket is in contact with the top edge of the lower mounting bracket.

[0008] Furthermore, a fixing groove is provided on the inner side of the upper mounting bracket, and a fixing block matching the fixing groove is fixedly connected to the upper end of the inner side of the lower mounting bracket. The cross-section of the fixing block is a right trapezoid, and the bottom end of the fixing block is in contact with the bottom end of the inner side of the fixing groove.

[0009] Furthermore, the top of the upper mounting bracket is snapped with a panel, and the panel is fitted over the outside of the output interface. The bottom of the panel is connected with a snap-fit ​​block, and the surface of the upper mounting bracket is provided with a snap-fit ​​groove that matches the snap-fit ​​block. The cross-section of the snap-fit ​​block is "J" shaped, and the bottom end of the snap-fit ​​block passes through and extends to the lower end of the upper mounting bracket.

[0010] Furthermore, the heat dissipation mechanism includes heat dissipation holes, which are opened on the outside of the lower mounting frame. Heat dissipation fins are provided on the outer side of the lower mounting frame, and the heat dissipation holes and heat dissipation fins are staggered.

[0011] Furthermore, the heat dissipation holes are equally spaced on the outside of the lower mounting bracket, and the heat dissipation fins are disposed at one end between the heat dissipation holes.

[0012] Furthermore, a heat-conducting sheet is installed on the side of the electronic component packaging assembly, and the heat-conducting sheet is arranged in an "L" shape, with a heat dissipation groove on the outer side of the heat-conducting sheet.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By converting a quasi-square wave into a sine wave, the output waveform is a continuous and smooth sine wave. This waveform is closer to the form of ideal alternating current, which helps to reduce harmonic interference and electromagnetic noise. Furthermore, the spectrum of the sine wave is concentrated near the fundamental wave, with less harmonic content. This helps to reduce interference to the power grid and other equipment. In addition, sine wave power supplies can reduce the risk of equipment damage caused by waveform distortion and extend the service life of equipment.

[0015] Furthermore, by pressing and pulling the side of the upper mounting bracket upwards, the positioning groove and the positioning block are separated. At the same time, when moving upwards, a gap is created between the fixing block and the fixing groove. When pressure is applied to the side of the upper mounting bracket, the side of the fixing groove is moved inwards synchronously, thereby separating the fixing block and the fixing groove, which facilitates the internal maintenance of the power adapter.

[0016] Furthermore, by utilizing the shape of the fixing block, the bottom end of the fixing block can fit against the lower end of the inner side of the fixing groove, thereby making the fixing block and the fixing groove fit more tightly, thus achieving a stable engagement between the upper mounting bracket and the lower mounting bracket.

[0017] 2. By utilizing the fan and the heat dissipation holes on the outside of the lower mounting bracket, the heat inside the power adapter can be discharged, thus effectively preventing the internal temperature of the power adapter from becoming too high. At the same time, when the fan blows air into the interior of the lower mounting bracket, the heat dissipation holes are evenly distributed on the outside of the lower mounting bracket, allowing the heat to dissipate from the heat dissipation holes.

[0018] Furthermore, the heat-conducting pads installed inside the lower mounting bracket can assist in the heat dissipation of the electronic component packaging components, preventing heat buildup that cannot be dissipated during long-term operation. The heat dissipation grooves on the surface of the heat-conducting pads facilitate air circulation. When the fan dissipates heat from the inside of the lower mounting bracket, the heat-conducting pads increase the heat dissipation area, while the heat dissipation grooves assist in air circulation, ensuring better heat dissipation.

[0026] 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.

[0027] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 6The technical solution shown addresses the problem that traditional power adapters require separate tools for complete disassembly when internal faults occur, hindering repair efficiency and leading to decreased repair efficiency. This quick-release travel charger discloses a quick-release mechanism, including an upper mounting bracket 1. The upper mounting bracket 1 has an output interface 3 at its top and an input interface 4 on its side. A power switch 5 is mounted at the top of the upper mounting bracket 1 near the output interface 3. An electronic component package 16 is mounted on the side inside the upper mounting bracket 1. A lower mounting bracket 15 is snapped into place at the bottom of the upper mounting bracket 1. A quick-release mechanism for quickly removing the upper mounting bracket 1 is provided on the side of the top of the lower mounting bracket 15. The quick-release mechanism includes a positioning block 6, which is fixedly connected to the lower mounting bracket 1. The top of the mounting bracket 15 and the bottom of the upper mounting bracket 1 are provided with a positioning groove 7 that matches the positioning block 6; the thickness of the positioning block 6 is less than the thickness at the top edge of the lower mounting bracket 15, and the bottom of the upper mounting bracket 1 is in contact with the top edge of the lower mounting bracket 15; a fixing groove 10 is provided on the inner side of the upper mounting bracket 1, and a fixing block 9 that matches the fixing groove 10 is fixedly connected to the upper end of the inner side of the lower mounting bracket 15. The cross-section of the fixing block 9 is a right trapezoid, and the bottom end of the fixing block 9 is in contact with the bottom end of the inner side of the fixing groove 10; a panel 2 is snapped onto the top of the upper mounting bracket 1, and the panel 2 is sleeved on the outside of the output interface 3. A snap-fit ​​block 8 is connected to the bottom end of the panel 2, and a snap-fit ​​groove 18 that matches the snap-fit ​​block 8 is provided on the surface of the upper mounting bracket 1. The cross-section of the snap-fit ​​block 8 is "J" shaped, and the bottom end of the snap-fit ​​block 8 passes through and extends to the lower end of the upper mounting bracket 1.

[0028] In this example, most power adapters utilize thyristor choppers to convert 220V to 110V. However, thyristor choppers produce significant ripple and voltage fluctuations in the output waveform, which may adversely affect sensitive electronic equipment. Conversely, using a quasi-square wave to convert to a sine wave results in a continuous and smooth sine wave output. This waveform is closer to the ideal form of alternating current, which helps reduce harmonic interference and electromagnetic noise. Furthermore, the sine wave spectrum is concentrated near the fundamental frequency, with fewer harmonics, which helps reduce interference to the power grid and other equipment. Sine wave power supplies also reduce the risk of equipment damage due to waveform distortion, extending equipment lifespan. Since the power adapter needs to be quickly disassembled and repaired in case of failure, pressing and pulling upwards on the side of the upper mounting bracket 1 engages the positioning slot 7 and the positioning block 6. When the upper mounting bracket 1 and the lower mounting bracket 15 are separated, a gap is created between the fixing block 9 and the fixing groove 10 when the upper mounting bracket 1 is moved upward. When pressure is applied to the side of the upper mounting bracket 1, the side of the fixing groove 10 is moved inward synchronously, thereby separating the fixing block 9 and the fixing groove 10. The shape of the fixing block 9 allows the bottom end of the fixing block 9 to fit against the lower end of the inner side of the fixing groove 10, thereby making the fixing block 9 and the fixing groove 10 fit more tightly, thus achieving a stable engagement between the upper mounting bracket 1 and the lower mounting bracket 15. After the upper mounting bracket 1 and the lower mounting bracket 15 are separated and disassembled, the snap-fit ​​block 8 is pushed inward, thereby separating the snap-fit ​​block 8 from the snap-fit ​​groove 18, thus achieving the separation between the panel 2 and the upper mounting bracket 1, facilitating a more thorough and quick disassembly and assembly of the power adapter.

[0029] Example 2: Figure 1 , Figure 2 , Figure 4 and Figure 5 The technical solution shown addresses the problem of excessive internal temperature affecting the lifespan of internal electronic components during prolonged use of a power adapter. This quick-release travel charger discloses a heat dissipation mechanism. A fan 12 is mounted on the side of the lower mounting bracket 15, and a heat dissipation mechanism for assisting the fan 12 in conducting heat is provided on the outer side of the lower mounting bracket 15. The heat dissipation mechanism includes heat dissipation holes 13, which are located on the outside of the lower mounting bracket 15. Heat dissipation fins 14 are provided on the outer side of the lower mounting bracket 15, with the heat dissipation holes 13 and heat dissipation fins 14 staggered. The heat dissipation holes 13 are evenly spaced on the outside of the lower mounting bracket 15, and the heat dissipation fins 14 are located at one end between the heat dissipation holes 13. A heat-conducting plate 11 is mounted on the side of the electronic component packaging assembly 16, and the heat-conducting plate 11 is L-shaped. A heat dissipation groove 17 is provided on the outer side of the heat-conducting plate 11.

[0030] In this example, the power adapter generates heat during use. To prevent excessive internal temperature from affecting the lifespan of internal electronic components, the heat is dissipated by the interaction between the fan 12 and the heat dissipation holes 13 on the outer side of the lower mounting bracket 15. This effectively prevents the internal temperature of the power adapter from becoming too high. Simultaneously, when the fan 12 blows air into the lower mounting bracket 15, the heat dissipation holes 13 are evenly distributed on the outer side of the lower mounting bracket 15, allowing heat to dissipate through these holes, preventing heat from being trapped due to the closed interior of the lower mounting bracket 15. Furthermore, heat dissipation fins 14 are also provided on the outer side of the lower mounting bracket 15, utilizing the interaction between the heat dissipation holes 13 and the heat dissipation fins 14. The combined design increases the heat dissipation efficiency of the lower mounting bracket 15 during use, effectively increasing the heat dissipation area of ​​the power adapter. Furthermore, the distribution of the heat dissipation fins 14 increases the contact area when the power adapter is handled, preventing slippage and enhancing usability. The heat-conducting plates 11 inside the lower mounting bracket 15 assist in heat dissipation of the electronic component packaging assembly 16, preventing heat buildup during prolonged operation. The heat dissipation grooves 17 on the surface of the heat-conducting plates 11 facilitate airflow. When the fan 12 dissipates heat from the interior of the lower mounting bracket 15, the heat-conducting plates 11 increase the heat dissipation area, while the heat dissipation grooves 17 facilitate airflow, ensuring better heat dissipation.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
