Description

adapter Technical Field

[0001] This work belongs to the field of electronic accessories, specifically concerning an adapter. Prior Technology

[0002] The widespread use of mobile electronic devices and their increasingly frequent daily use have increased the demand for chargers. With the widespread use of electronic devices such as smartphones, tablets, and wearable devices, users not only demand charging efficiency but also require chargers that are smaller, safer, and more durable. Current chargers often feature simple, inflexible plug designs that cannot simultaneously charge a wide variety of electronic products. Furthermore, traditional chargers suffer from poorly designed internal heat dissipation structures, failing to fully utilize space for effective heat dissipation. This leads to overheating of chips and power components, affecting lifespan and stability, and posing safety hazards.

[0003] Therefore, traditional chargers can no longer meet the current demands for high efficiency and safety. How to charge different devices while ensuring heat dissipation and safety is an urgent problem to be solved. Summary of the Invention

[0004] The main purpose of this invention is to provide an adapter that addresses the aforementioned issues, such as poor heat dissipation and safety hazards associated with existing chargers.

[0005] To achieve the above objectives, this invention provides an adapter, including a housing, an interface, a first pin, and a circuit board, wherein one end of the housing is open and is connected to a top cover; The interface and the first pin are electrically connected to the circuit board, and the first pin is used to connect the power supply to power the interface and the circuit board. The interface and the first pin are respectively located on different inner sides of the housing. The circuit board is located close to the interface and the first pin, forming a cavity structure inside the housing. The cavity is connected to the outside through the heat dissipation holes at the connection between the housing and the top cover.

[0006] Optionally, a display screen is provided on one side wall of the housing. The display screen is electrically connected to the circuit board, and the circuit board is provided with a temperature sensing element to provide temperature data to the display screen.

[0007] Optionally, a first bracket is provided between the display screen and the first side plate of the circuit board, with one side of the first bracket connected to the display screen and the other side connected to the circuit board.

[0008] Optionally, the area of ​​the first bracket is smaller than the area of ​​the display screen and the side wall of the housing, forming a structure in which one end of the first side plate has a first gap with the side wall.

[0009] Optionally, a spring is provided in the first gap, with one end of the spring located on the display screen and the other end electrically connected to the first side plate.

[0010] Optionally, the cavity is provided with a first support plate and a second support plate that are perpendicularly connected to each other. The first support plate is located on the outer periphery of the interface, and the second support plate is parallel to the second side plate of the circuit board and located on the side of the second side plate near the cavity, forming a structure in which the first support plate and the second support plate surround the interface and the second side plate.

[0011] Optionally, the second support plate is connected to the third side plate of the circuit board, and the second support plate extends out of the third side plate through a through hole, forming a portion of the second support plate located in the second gap between the third side plate and the outer casing.

[0012] Optionally, the outer casing includes a first housing and a second housing disposed near the cavity, the first housing and the second housing being spaced apart to form a double-layer structure.

[0013] Optionally, the first pin is detachably connected to the housing.

[0014] Optionally, multiple interfaces may be provided.

[0015] Optionally, the adapter connects to a smart voice element, which is located inside the cavity and electrically connected to the circuit board for recognizing the user's voice.

[0016] This innovative technical solution utilizes a structured design for the adapter's internal structure. The various functional modules—interface, first pin, and display screen—are independently positioned on three different inner sides of the casing. The circuit board is positioned close to the interface, first pin, and display screen, creating an independent and complete cavity within the casing. This independent cavity allows for reserved heat-conducting space around the interface, first pin, display screen, and circuit board, preventing localized overheating caused by the accumulation of electronic components. Furthermore, the heat dissipation holes at the connection between the top cover and the casing, connected to the external environment, effectively guide heat dissipation, ensuring safe operation. The interface, first pin, and display screen are set up independently, which distinguishes each function and improves the non-interference between internal components. At the same time, each component can work and be replaced independently. For example, the first pin can be replaced to adapt to sockets in different countries without affecting the operation of the interface and display screen. Structurally, the cavity can be used to dissipate heat for each independent functional module. In particular, the circuit board is exposed inside the cavity and can be directly cooled through the heat dissipation holes. After the interface, the first pin, the display screen, and the circuit board are set up, heat dissipation can be further achieved through the first bracket, the first support plate, and the second support plate. This not only improves the stability of the connection but also facilitates heat dissipation through the enhanced cavity, thereby enabling safe and efficient operation.

[0021] The widespread use of electronic devices, such as smartphones, tablets, and wearable devices, is increasing in daily use. This has increased the demand for chargers and placed higher requirements on them. They not only need to be able to charge multiple devices efficiently and be plugged in and unplugged multiple times, but also ensure safety and reliability during use, while being easy to carry and store.

[0022] In pursuit of miniaturization, current technologies typically compress internal space, leading to decreased heat dissipation. Adding heat dissipation components increases production costs, while omitting heat dissipation structures can create safety hazards due to the heat generated by internal components. This is particularly true in size-constrained portable chargers, where the compression of heat dissipation structures to ensure the safe and stable operation of critical heat-generating components such as chips, electronic components, and interfaces results in even more serious safety hazards in these high-temperature areas.

[0023] Moreover, in existing technologies, electronic components are densely stacked, with multiple high-heat components often arranged compactly on the circuit board. There is a lack of physical isolation between hot areas, resulting in severe thermal interference and easy formation of localized overheating and heat transfer between them.

[0024] Therefore, the requirements for chargers are becoming increasingly stringent. Traditional chargers can no longer meet the current demands for high efficiency and safety. How to perform multiple plugging and unplugging operations and charge different devices while meeting safety requirements is an urgent problem to be solved.

[0025] To address this, this invention provides an adapter 100, as shown in Figures 1 and 2. The interface 20, first pin 30, and display screen 50 are respectively disposed on different inner surfaces of the housing 10, forming independent working spaces for each part, thus preventing interference. The circuit board 40 encloses the housing 10, forming a cavity 11 in the center of the adapter 100. The cavity 11 can cooperate with each independent functional module for heat dissipation. The cavity 11 is further connected to the outside through heat dissipation holes 15, exchanging internal heat with external air. The interface 20, first pin 30, and display screen 50 are electrically connected. The first pin 30 is used to connect a power source to power the interface 20 and display screen 50. The interface 20 can connect to the data cable of an external electronic device for charging. The display screen 50 can display the current temperature of the adapter 100, thereby cutting off the power when the temperature is too high to avoid safety hazards. On the one hand, the adapter 100 can operate while dissipating heat; on the other hand, it can monitor and provide alerts regarding the operating temperature, providing a safe and efficient charging method. This adapter 100 has the following specific embodiments:

[0026] Example 1: Referring to Figures 3 to 6, the first pin 30 and the display screen 50 are respectively disposed on the two opposite inner sidewalls of the housing 10, and the interface 20 is disposed between the first pin 30 and the display screen 50. This facilitates the user's viewing of the display screen 50 and the plugging and unplugging of data cables of external electronic devices on the interface 20 after the first pin 30 is connected to the power supply. The circuit board 40 includes a first side plate 41 connected to the display screen 50, a second side plate 42 connected to the interface 20, a third side plate 43 disposed on the inner wall of the housing 10, and a fourth side plate connected to the first pin 30. The first side plate 41, the second side plate 42, the third side plate 43, and the fourth side plate are all electrically connected to each other. The first side plate 41, the second side plate 42, and the third side plate 43 enclose a cavity 11 and are disposed inside the cavity 11 and in direct contact with the cavity 11 to dissipate heat directly to the cavity 11. The first side plate 41, the second side plate 42, the third side plate 43, and the fourth side plate are all disposed on different sides inside the housing 10 to avoid heat concentration. The outer casing 10 has an opening at one end and is connected to the upper cover 14 at the opening. The connection between the upper cover 14 and the outer casing 10 has a heat dissipation hole 15, meaning that the outer casing 10 and the upper cover 14 are not sealed together. This creates a structure in which the heat dissipation hole 15 communicates with the cavity 11 and the external environment. The cavity 11 communicates with the external air through the heat dissipation hole 15 to dissipate heat. Furthermore, referring to Figures 4 and 5, a first bracket 51 is provided between the display screen 50 and the first side panel 41. The first bracket 51 is used to connect the display screen 50 and the first side panel 41, and the area of ​​the first bracket 51 is smaller than the area of ​​the display screen 50 and the side wall of the housing 10, forming a structure in which one end of the display screen 50 and the first side panel 41 have a first gap 411, so that the first side panel 41 is exposed to the first gap 411, and the first gap 411 can dissipate heat from the first side panel 41. Optionally, decorative elements 70 can be provided on the side walls of the display screen 50 and the housing 10 to allow the user to see the content of the display screen 50 while preventing the display screen 50 from being exposed to the outside, thus protecting the display screen 50. Preferably, a spring 52 is provided in the first gap 411, with one end of the spring 52 located on the display screen 50 and the other end located on the first side plate 41. The spring 52 can be used to control the display screen 50 by pressing a switch and can also provide cushioning. Further, referring to Figure 6, a first support plate 61 and a second support plate 62 are provided perpendicularly connected within the cavity 11. The first support plate 61 and the second support plate 62 are connected to the circuit board 40 to form a PCBA structure. Specifically, the first support plate 61 is located on one side of the interface 20, and the second support plate 62 is arranged parallel to the second side plate 42, forming a structure in which the second side plate 42 is located between the second support plate 62 and the interface 20. The second support plate 62 partially extends out of the third side plate 43 through the through hole 431 on the third side plate 43, forming a portion of the second support plate 62 located in the second gap 621 between the third side plate 43 and the outer shell 10. The second gap 621 further provides heat dissipation space. One side of the third side plate 43 is exposed in the cavity 11, and the other side is exposed in the second gap 621 to avoid heat accumulation. Further, referring to Figure 3, the outer casing 10 includes a first casing 12 and a second casing 13 disposed near the cavity 11. The first casing 12 and the second casing 13 are spaced apart to form a double-layer structure. Optionally, any side wall of the outer casing 10 can be configured as a double-layer structure with the first casing 12 and the second casing 13 spaced apart, or both can be configured as double-layer structures. An airflow path can be formed between the first casing 12 and the second casing 13. When the adapter 100 generates heat during operation, hot and cold air naturally convection within the gap, which helps to quickly remove heat. Preferably, multiple interfaces 20 are provided, and different types of interfaces 20 can be set, such as USB interface, Lightning interface and Type-C interface, etc. In this embodiment, four interfaces 20 are provided and are spaced apart to meet the needs of charging different devices at the same time; This embodiment provides a variety of heat dissipation structures, such as cavity 11 and heat dissipation holes 15. At the same time, the separate functional modules divide the structure of the housing 10 and the area inside the housing 10, so that each functional module (interface 20, first pin 30 and display screen 50) can achieve multiple effective heat dissipation. In particular, the circuit board 40 is directly exposed to the cavity 11, and the cavity 11 dissipates heat from the circuit board 40 directly through the heat dissipation holes 15, which improves the heat dissipation efficiency. Thus, the adapter 100 has good heat dissipation performance and can be better used for device charging.

[0027] Example 2: Based on Embodiment 1, the outer casing 10 has an opening at one end facing the first pin 30, and a top cover 14 is provided at the opening. The first pin 30 and the display screen 50 are respectively located on the side away from the interface 20 to avoid heat concentration and effectively prevent mutual interference between functional modules. Multiple heat dissipation holes 15 can be provided on the outer casing 10 or the top cover 14, or the heat dissipation holes 15 can be located in other positions to further accelerate air circulation. Furthermore, the adapter 100 is connected to a smart voice element, which is located inside the cavity 11 and electrically connected to the first pin 30. The smart voice element is used to recognize the user's voice to interact with the user. For example, the user can ask about the temperature and charging status, and the adapter 100 can respond through the voice element. Alternatively, the smart voice element can access the Internet to enable smart communication with the user and use as a smart home device. The first pin 30 is mounted on a pressure plate 80 inside the outer casing 10 via a pivot and is located at the opening of the outer casing 10. It is then fixedly connected to the upper cover 14 via the pressure plate 80, which allows the first pin 30 to be unfolded or folded. The upper cover 14 has a groove specifically for accommodating the first pin 30, so as to make the device smaller and easier to carry. Preferably, referring to Figure 7, the first pin 30 is detachably connected to the housing 10. For example, the second pin 90 can be replaced. The second pin 90 is installed and replaced by sliding into the connecting groove on the pressure plate 80 through the mounting part 91, so as to connect to sockets of different countries or different shapes, thus enriching the application scenarios. Optionally, multiple different decorative parts 70 can be set to decorate the housing 10 to increase the aesthetics of the adapter 100 and enhance the visual experience.

[0028] In this embodiment, while improving heat dissipation performance, the functions of adapter 100 are increased, enhancing the intelligence of adapter 100, and making the device more usable and more versatile to meet different user needs.
