Description

Technical Field

[0001] This utility model relates to the field of automotive electronic components technology, and in particular to an in-vehicle USB dual-port charging module. Background Technology

[0002] With the development of automotive intelligence and electrification, USB interfaces have become a standard feature in automotive interiors, mainly used for charging electronic devices such as mobile phones and tablets, or for data transfer between devices and the vehicle's infotainment system. However, existing in-vehicle USB charging modules have some shortcomings: on the one hand, the USB interface is exposed and is prone to dust and debris entering, which can lead to poor contact, affecting the charging effect or even damaging the interface over time; on the other hand, the circuit connection structure of some modules is not stable enough, and conductive parts are prone to loosening in the bumpy environment of driving, causing charging interruption. Utility Model Content

[0003] To overcome the technical defects of existing technologies, this utility model provides a vehicle-mounted USB dual-port charging module. The module is equipped with a transparent plastic dust cover with a damping hinge and an adapter slot. When the USB interface is not in use, it can be tightly plugged in to effectively prevent dust and avoid poor contact due to dust, thereby improving the interface life and charging stability. The conductive post and the conductive plate are connected by an initially compressed spring. The elastic conductive sheet is made of copper alloy and has an insulating limit cover. The spring force ensures that the conductive post is always in close contact with the cigarette lighter conductive sheet. The elastic conductive sheet can also stably abut against the integrated circuit board when the car is bumpy, ensuring a stable power supply circuit and solving the problem of charging interruption caused by loose conductive parts in existing modules, thus ensuring continuous and smooth charging.

[0004] The technical solution adopted by this utility model is: a vehicle-mounted USB dual-port charging module, including a housing, an integrated circuit board fixedly installed inside the housing, two USB ports electrically connected to the integrated circuit board, a cover plate installed on the top of the housing, an adapter port provided on the surface of the cover plate, a dust cover rotatably connected to the adapter port through a damping hinge, and the dust cover is inserted into the interface of the USB port. A conductive plate is installed inside the housing below the integrated circuit board. The conductive plate is connected to the integrated circuit board by wires. The conductive plate is provided with conductive posts. A spring is connected between the conductive plate and the conductive posts. The conductive posts pass through the housing and abut against the conductive sheet at the bottom of the vehicle's cigarette lighter. An elastic conductive sheet is installed on one side of the housing and abuts against the integrated circuit board. A through hole is provided on the cover plate corresponding to the USB interface, and an indicator light is installed inside the through hole. The indicator light is electrically connected to the integrated circuit board.

[0005] Preferably, the inner wall of the housing is provided with an insulating limiting cover, which is sleeved on the outside of the elastic conductive sheet.

[0006] Preferably, the elastic conductive sheet is made of copper alloy.

[0007] Preferably, the spring is a compression spring, and the initial state is a compressed state.

[0008] Preferably, the dust cover is made of transparent plastic material, with a slot at the bottom that is compatible with the USB interface, and a handle at the top.

[0009] Preferably, the surface of the handle is provided with an anti-slip texture.

[0010] Preferably, the indicator light is an LED light.

[0011] The beneficial effects of this utility model are: The module is equipped with a transparent plastic dust cover that is connected by a damped hinge and has an adapter slot at the bottom. When the USB interface is not in use, it can be tightly inserted into the interface to effectively prevent dust and debris from entering. Compared with the existing exposed interface, it can avoid poor contact caused by dust accumulation, greatly improve the interface life and charging stability, and allow users to not worry about interface contamination affecting the charging effect. The conductive post and the conductive plate are connected by a compression spring in an initial compressed state. The elastic conductive sheet is made of copper alloy and has an insulating limit cover on the outside for limiting. The elasticity of the spring ensures that the conductive post is always in close contact with the conductive sheet at the bottom of the car cigarette lighter. The elastic conductive sheet, with its own elasticity and the properties of copper alloy, can still stably contact the integrated circuit board when the car is bumpy. The constructed power supply circuit is stable and reliable, which solves the problem of charging interruption caused by loose conductive parts in existing modules and ensures a continuous and smooth charging process.

[0018] The present invention will be further described below with reference to the accompanying drawings: like Figure 1-5 As shown, this embodiment provides a vehicle-mounted USB dual-port charging module, including a housing 1, an integrated circuit board 2 fixedly installed inside the housing 1, two USB ports 3 connected to the integrated circuit board 2 when powered on, a cover plate 5 installed on the top of the housing 1, an adapter port 6 provided on the surface of the cover plate 5, a dust cover 7 rotatably connected to the adapter port 6 through a damping hinge 14, and the dust cover 7 is inserted into the interface of the USB port 3. A conductive plate 11 is provided inside the housing 1 below the integrated circuit board 2. The conductive plate 11 is connected to the integrated circuit board 2 by a wire. The conductive plate 11 is provided with a conductive post 10. A spring 9 is connected between the conductive plate 11 and the conductive post 10. The conductive post 10 passes through the housing 1 and abuts against the conductive sheet at the bottom of the cigarette lighter in the vehicle. An elastic conductive sheet 8 is installed on one side of the housing 1 and abuts against the integrated circuit board 2. A through hole 15 is provided on the cover plate 5 at the position corresponding to the USB interface 3. An indicator light 16 is provided in the through hole 15, and the indicator light 16 is electrically connected to the integrated circuit board 2.

[0019] The housing 1 serves as the mounting base and protective structure for the entire module. It provides physical support and protection for all internal components, including the integrated circuit board 2 and conductive plate 11, preventing damage from external collisions and vibrations. It also isolates the module from dust, moisture, and other impurities, ensuring stable operation in the complex in-vehicle environment. The integrated circuit board 2 integrates the necessary charging circuitry, converting the vehicle's power supply into voltage and current suitable for charging electronic devices, enabling precise control of the charging process. It also provides stable power supply and signal control for the two USB ports 3 and indicator lights 16, making it crucial for the module's charging function. The two USB ports 3 allow users to charge two electronic devices (such as mobile phones and tablets) simultaneously, providing a more efficient charging experience. The module's practicality and convenience are enhanced, adapting to scenarios where multiple devices use power simultaneously. The cover plate 5 installed on the top of the housing 1 not only provides secondary protection for components such as the integrated circuit board 2 inside the housing 1, but also provides a mounting carrier for the adapter port 6 and through hole 15, making the overall structure of the module more regular and enhancing its dustproof and moisture-proof capabilities. The adapter port 6 provides an external access channel for the USB interface 3, making it convenient for users to insert the charging cable into the USB interface 3. Its size matches the USB interface 3 and the dust cover 7, ensuring smooth access for the charging cable and providing a suitable position for the installation of the dust cover 7. The dust cover 7, connected by the damping hinge 14, can rotate flexibly. When the USB interface 3 is not in use, the dust cover 7 is inserted into the interface of the USB interface 3. The system effectively prevents dust and debris from entering the interface, avoiding poor contact or damage due to contamination. The damping hinge 14 provides appropriate resistance during the opening and closing of the dust cover 7, allowing it to remain at any angle for easy user operation. The conductive plate 11 acts as a current transfer and conduction mechanism, transmitting the power supplied by the conductive post 10 to the integrated circuit board 2 via wires. It also provides a mounting base for the spring 9 and the conductive post 10, ensuring a stable power transmission path. The conductive post 10 penetrates the housing 1 and abuts against the conductive plate at the bottom of the vehicle's cigarette lighter. It is a key component for the module to obtain the positive terminal of the vehicle's power supply. Its material has good conductivity, ensuring efficient power transmission. The spring 9 connects the conductive plate 11 and the conductive post 10, using its elasticity to keep the conductive post 10 in contact with the vehicle's power supply. The conductive sheet at the bottom of the cigarette lighter is in close contact, ensuring the stability of the power connection and preventing charging interruption even when the car is bumpy. The elastic conductive sheet 8 is installed on one side of the housing 1 and abuts against the integrated circuit board 2. On the one hand, it serves as a conduction path for the negative terminal of the power supply, forming a circuit with the metal part of the inner wall of the cigarette lighter. On the other hand, it utilizes its elastic properties to maintain good contact with the integrated circuit board 2 even under vibration, ensuring stable current transmission. The through hole 15 on the cover plate 5 provides a light emission channel for the indicator light 16. The indicator light 16 is electrically connected to the integrated circuit board 2 and can intuitively reflect the charging status of the USB interface 3 (such as charging, fully charged, etc.). Users can clearly observe the status of the indicator light 16 through the through hole 15, making it convenient to understand the charging progress.

[0020] Furthermore, an insulating limiting cover 4 is provided on the inner wall of the housing 1, and the insulating limiting cover 4 is sleeved on the outside of the elastic conductive sheet 8.

[0021] The insulating limiting cover 4, which is sleeved on the outside of the elastic conductive sheet 8, serves two purposes: firstly, it limits the position of the elastic conductive sheet 8 to prevent it from shifting during vibration or long-term use, thus ensuring stable contact with the integrated circuit board 2; secondly, it is made of insulating material, which can effectively prevent the elastic conductive sheet 8 from contacting the housing 1 or other metal parts and causing a short circuit, thereby improving the electrical safety of the module.

[0022] Furthermore, the elastic conductive sheet 8 is made of copper alloy.

[0023] Copper alloys have excellent electrical conductivity, which can reduce losses during current transmission and ensure charging efficiency. At the same time, copper alloys have good elasticity and wear resistance. Even under long-term contact with the integrated circuit board 2 and the vibration environment of automobiles, they can still maintain good elastic deformation capacity and structural stability, which extends the service life of the elastic conductive sheet 8 and ensures the long-term stability of the power supply negative circuit.

[0024] Furthermore, spring 9 is a compression spring, and its initial state is a compressed state.

[0025] The compression spring 9 is in a compressed state in the initial state, which can continuously apply an upward elastic force to the conductive post 10, so that the conductive post 10 always tightly abuts against the conductive piece at the bottom of the car cigarette lighter. Even in the bumpy and shaking environment of the car, it can effectively compensate for the gap caused by vibration, ensure the reliability of the positive terminal connection of the power supply, and avoid charging interruption caused by poor contact.

[0026] Furthermore, the dust cover 7 is made of transparent plastic material, and the bottom of the dust cover 7 is provided with a slot 13, which is compatible with the USB interface 3. The top of the dust cover 7 is provided with a handle 12.

[0027] The transparent material allows users to observe the status of the indicator light 16 and understand the charging status through the dust cover 7 without opening it. The slot 13, which is compatible with the USB interface 3, allows the dust cover 7 to fit precisely with the USB interface 3 when closed, forming a tight fit, which enhances the dustproof effect and prevents dust from entering the interface through gaps. The handle 12, located on the top of the dust cover 7, provides users with a convenient point of force, making it easy for users to open and close the dust cover 7 and improving the convenience of operation.

[0028] Furthermore, the surface of the handle 12 is provided with an anti-slip texture.

[0029] The anti-slip texture on the surface of the handle 12 increases the friction between the hand and the handle 12, preventing slippage and further improving the ease of operation.

[0030] Furthermore, indicator light 16 is an LED light.

[0031] LED lights are characterized by low energy consumption, which can reduce the consumption of vehicle power; they are also bright, so even in bright in-vehicle environments, users can clearly see the status of indicator light 16.

[0032] The working principle of this utility model is as follows: The module as a whole integrates and installs all components through the housing 1. The integrated circuit board 2, as the core control component, is fixedly installed inside the housing 1. It integrates the charging control circuit and related electronic components. The module is powered by the car cigarette lighter interface. The conductive post 10 passes through the bottom of the housing 1 and abuts against the conductive sheet at the bottom of the car cigarette lighter to form a positive power input path. At the same time, the elastic conductive sheet 8 installed on one side of the housing 1 abuts against the integrated circuit board 2. The elastic conductive sheet 8 contacts the metal part of the inner wall of the cigarette lighter to form a negative power circuit, thereby constructing a complete power supply circuit. A compression spring 9 in an initial compressed state is connected between the conductive post 10 and the conductive plate 11. Under the elastic force of the spring 9, the conductive post 10 always maintains close contact with the conductive piece at the bottom of the vehicle cigarette lighter. At the same time, the conductive plate 11 is electrically connected to the integrated circuit board 2 through wires to transmit the input vehicle power to the integrated circuit board 2. The elastic conductive sheet 8 is made of copper alloy, which has good conductivity and elasticity. The outer side is fitted with an insulating limit cover 4 on the inner wall of the housing 1, which not only ensures the stable contact between the elastic conductive sheet 8 and the integrated circuit board 2, but also avoids short circuits caused by contact with other metal parts. When the car is moving and there are bumps, the elastic deformation of the spring 9 and the elastic conductive sheet 8 can buffer the vibration and shock, and ensure the continuous stability of the power connection. The charging control circuit integrated on the integrated circuit board 2 converts the input vehicle power supply into a voltage and current suitable for charging electronic devices. It provides charging services for external devices through two USB ports 3. The adapter port 6 on the surface of the cover plate 5 provides an external access channel for the USB ports 3. Users can insert the device charging cable into the USB ports 3 through the adapter port 6 for charging. An LED indicator 16 electrically connected to the integrated circuit board 2 is installed in the through hole 15 on the cover plate 5 corresponding to the position of the USB interface 3. When the USB interface 3 is connected to the device for charging, the integrated circuit board 2 controls the corresponding LED indicator 16 to light up. The charging process can be intuitively reflected by different colors (such as red to indicate charging and green to indicate full charge, this technology is well known to those skilled in the art and will not be described in detail here) or flashing status. Users can clearly observe the status of the indicator 16 through the through hole 15. The dust cover 7, which is connected to the adapter port 6 by a damping hinge 14, is made of transparent plastic. The slot 13 at the bottom of the cover is adapted to the USB interface 3. When the USB interface 3 is not in use, the dust cover 7 can be rotated to the closed position by the damping hinge 14 and inserted into the interface of the USB interface 3. The slot 13 and the USB interface 3 cooperate to achieve a tight seal, effectively preventing dust and debris from entering the interface. The handle 12 with anti-slip texture on the top of the dust cover 7 makes it easy for users to open and operate. The transparent material allows users to observe the status of the indicator light 16 without opening the dust cover 7.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
