Description

Technical Field

[0001] This utility model belongs to the field of automotive parts and general machinery, and specifically relates to a car audio system with multiple charging outputs. Background Technology

[0002] Traditional cars are only equipped with a cigarette lighter socket, requiring an external converter to power mobile devices. However, cigarette lighters and chargers cannot coexist, requiring users to switch frequently, increasing driving safety hazards (such as distraction or inability to quickly access the device in an emergency). At the same time, older car audio systems generally lack charging functionality, failing to meet the charging needs of multiple devices such as mobile phones, tablets, and Bluetooth headsets. Furthermore, car phone holders rely on mechanical clamps, which can easily cause devices to shift, fall off, or even be damaged on bumpy roads, making deep integration with charging functionality impossible.

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0033] like Figure 1-11As shown, this utility model provides a car audio system with multiple charging outputs, including a main unit 1. The main unit 1 includes an upper layer 11, a lower layer 12, and a front cover 13. The upper layer 11 and the lower layer 12 are vertically aligned. The front cover 13 is detachably connected to the upper layer 11 and the lower layer 12. The front cover 13 is provided with a first charging port 131 and a second charging port 132. The first charging port 131 is used for USB power supply, and the second charging port 132 is used for Type-C cable power supply. Since almost everyone in today's society has mobile devices such as mobile phones, tablets, and Bluetooth headsets, charging these mobile devices is a problem when going out. Older cars usually do not have direct USB charging ports, and older car audio systems usually do not have USB charging functionality. When a user wants to charge their mobile phone, they can only do so by replacing the cigarette lighter socket with a USB charging dock. When a user lights a cigarette, they need to switch back to the cigarette lighter, which is inconvenient and poses a significant safety hazard while driving. Therefore, by designing charging interface 131 and charging interface 132, multiple charging interfaces are provided to meet the charging needs of commonly used mobile devices.

[0034] Among them, such as Figure 3-5 As shown, the lower layer 12 is provided with a storage box 2. The storage box 2 is detachably connected to the lower layer 12 and is fixedly connected to the lower layer 12 by fasteners such as screws. The lower layer 12 has no top cover, and has a storage box opening 24 at the front end and is hollow inside. The storage box 2 has a through hole 21, and a silicone component 3 is detachably connected to the through hole 21. The spring-loaded part 311 of the silicone component 3 extends into the storage box 2 through the through hole 21. When the mobile phone 5 is inserted into the storage box 2 through the storage box opening 24, the spring-loaded part 311 of the silicone component 3 presses the mobile phone 5 and thus fixes the mobile phone 5. When the mobile phone 5 is placed in the storage box 2, it will be firmly fixed when it encounters a bumpy road or sudden braking, ensuring that the mobile phone 5 will not be thrown out.

[0035] Preferably, the storage box 2 adopts a semi-exposed design for the mobile phone 5, which can ensure that the mobile phone 5 is effectively charged while making it convenient to pick up and put down the mobile phone 5, which is convenient for the driver to operate and has strong practicality.

[0036] Specifically, such as Figure 6-7 As shown, the storage box 2 includes an upper shell 22 and a lower shell 23. The silicone component 3 is disposed on the upper shell 22. The upper shell 22 is provided with a hook 221, and the lower shell 23 is provided with a connecting groove 231 adapted to the hook 221. In use, the upper shell 22 and the lower shell 23 are brought close together so that the hook 221 is engaged in the connecting groove 231, thereby enabling the upper shell 22 and the lower shell 23 to be quickly assembled. High-frequency vibration during car driving can easily cause parts to loosen. The barbed structure of the hook 221 is embedded in the connecting groove 231 to form a mechanical interlock.

[0037] In this embodiment, multiple sets of hooks 221 and connecting grooves 231 are provided to distribute stress and prevent single-point failure.

[0038] Furthermore, such as Figure 6 As shown, due to the continuous bumps in the car, the plastic hook may experience elastic fatigue. During sudden braking or collision, the inertial impact force of the phone 5 may exceed the latching force, resulting in slight loosening. Therefore, the upper shell 22 is also provided with a connecting block 1 222, and the lower shell 23 is provided with a connecting block 232 corresponding to the connecting block 1 222. The connecting block 1 222 and the connecting block 232 are fixedly connected by fasteners such as screws. The hook 221 slides into the connecting groove 231 to achieve quick and accurate alignment of the shell. The elastic pre-tightening force of the buckle eliminates the assembly gap, creating conditions for screw tightening and preventing the upper shell 22 and lower shell 23 from separating in extreme cases, which would cause the silicone component 3 to fail to press the phone 5, thus risking damage to the phone 5. By designing the buckle connection and the fastener fixing connection, a double fixation is achieved, ensuring the fixed connection between the upper shell 22 and lower shell 23 under extreme road conditions, so that the phone 5 in the storage box 2 has zero risk of falling out.

[0039] Specifically, the storage box 2 has a wireless charging module 4 at its bottom. In this embodiment, the wireless charging module 4 is located at the bottom of the lower shell 23 and can be used to wirelessly charge the mobile phone 5. When in use, the mobile phone 5 is inserted into the storage box 2. When the mobile phone 5 has wireless charging function, the wireless charging module 4 can power the mobile phone 5. Then, the charging interface 131 and the charging interface 132 can power the mobile phone 5 or power other mobile devices at the same time as the mobile phone 5 is wirelessly powered. By designing the wireless charging module 4, a car audio system can provide three charging functions (standard USB charging, Type-C charging, and wireless charging), and can charge three mobile phones 5 or other mobile devices at the same time, effectively preventing the mobile phone 5 from shifting or becoming polarized during driving, which could cause charging failure or damage.

[0040] Furthermore, the wireless charging module 4 includes a PCB board 41 and a coil 42. The PCB board 41 receives the low-voltage DC power converted by the host 1 and converts the low-voltage DC power into high-frequency AC power. The high-frequency AC power drives the coil 42 to generate an alternating magnetic field. The magnetic field passes through space and induces AC power in the receiver inside the mobile phone 5, which is then regulated into DC power to charge the mobile phone 5. At the same time, the PCB board 41 communicates with the mobile phone 5 to control the charging power and ensure safety. In use, when the operator places the wirelessly charging-enabled mobile phone 5 into the storage box 2, the wireless charging module 4 can supply power to the mobile phone 5.

[0041] Preferably, the wireless charging module 4 is provided with a heat sink 6 at the bottom. During the wireless charging process, the wireless charging module 4 will generate a lot of heat, and the high temperature will cause the resistance of the coil 42 to increase, thereby reducing the overall conversion efficiency. Therefore, the heat sink 6 is provided at the bottom of the coil 42 to dissipate heat and improve the charging efficiency. At the same time, the coil 42 is located at the bottom of the mobile phone 5. The heat sink 6 can reduce the temperature of the contact area between the bottom of the storage box 2 and the mobile phone 5, thereby improving the user experience and safety.

[0042] Specifically, such as Figure 7-8 As shown, the silicone component 3 includes a silicone sheet 31 and a pressure cover 32. The silicone sheet 31 includes a spring-loaded part 311 and a fixing part 312. The pressure cover 32 is fixedly connected to the fixing part 312, thereby fixing the silicone sheet 31 to the upper shell 22. The upper shell 22 is provided with a through hole 21. The spring-loaded part 311 passes through the through hole 21 and extends into the storage box 2 to press the inserted mobile phone 5. During use, when the mobile phone 5 is placed in the storage box 2, the upper end of the mobile phone 5 will squeeze the spring-loaded part 311, so that the spring-loaded part 311 is subjected to an upward squeezing force, causing the spring-loaded part 311 to move upward. When the mobile phone 5 is placed in the storage box 2, the spring-loaded part 311 restores its elastic deformation, thereby exerting downward pressure on the mobile phone 5, thereby fixing the mobile phone 5.

[0043] Specifically, a display screen 133 is provided on the outer surface of the front cover 13.

[0044] Specifically, such as Figure 9-11 As shown, a hidden door cover 134 is provided below the display screen 133. A placement slot 135 is located behind the hidden door cover 134 and is situated on the front cover 13. The placement slot 135 is used to accommodate the mobile phone 5 and corresponds to the opening 24 of the storage box. When in use, pressing the arrow on the hidden door cover 134 will cause it to flip open, allowing the mobile phone 5 to be placed in the placement slot 135. The mobile phone 5 is inserted into the storage box 2 through the opening 24 of the storage box via the placement slot 135 and is fixed by the spring-loaded part 311 of the silicone sheet 31. When not in use, pressing down on the lower part of the hidden door cover 134 will cause the hidden door cover 134 to rotate downwards to a position flush with the front cover 13, thus achieving a dustproof and waterproof effect. This prevents water or dust from entering the storage box 2 through the placement slot 135 and damaging the wireless charging module 4, etc. This design is simple and beautiful, and greatly saves workload.

[0045] Preferably, a door cover 7 and a door cover 8 are rotatably connected to the front cover 13. The door cover 7 corresponds to the charging interface 131, and the door cover 8 corresponds to the charging interface 132. The door cover 7 and the door cover 8 serve to prevent water and dust.

[0046] Furthermore, fixing blocks 136 are provided on both sides of the placement slot 135, and connecting holes 137 are provided on the fixing blocks 136. The hidden door cover 134 is provided with connecting posts 1341 that are adapted to the connecting holes 137. The hidden door cover 134 is rotatably connected to the fixing blocks 136 through the connecting posts 1341 and the connecting holes 137. In use, pressing the arrow above the hidden door cover 134 will cause the hidden door cover 134 to flip up and open. The hidden door cover 134 rotates to the top of the placement slot 135 through the connecting posts 1341 and the connecting holes 137. At this time, the mobile phone 5 can be inserted into the storage box 2 through the placement slot 135 for wireless charging.

[0047] Specifically, a button 138 is provided between the display screen 133 and the hidden door cover 134.

[0048] The following is a detailed explanation of the working principle of this utility model;

[0049] In use, the user presses the arrow above the hidden door cover 134, causing the hidden door cover 134 to flip open. The mobile phone 5, which needs to be charged, is then placed in the storage box 2 through the placement slot 135 behind the hidden door cover 134. The spring-loaded part 311 of the silicone sheet 31 on the storage box 2 secures the mobile phone 5, and the mobile phone 5 is semi-exposed at this time, making it convenient for the driver to operate. When the mobile phone 5 supports wireless charging, the wireless charging module 4 at the bottom of the storage box 2 wirelessly charges the mobile phone 5. The charging interface 131 and the charging interface 2 132 can power other mobile devices. When the mobile phone 5 does not support wireless charging, a charging cable can be inserted through the charging interface 131 or the charging interface 2 132 to charge the mobile phone 5.

[0050] The innovation of this utility model lies in the wireless charging module installed under the storage box to charge mobile phones, and the design of charging interface 1 and charging interface 2 on the front cover to provide multiple charging interfaces to meet the charging needs of various commonly used mobile devices. One car audio system can provide three charging functions (standard USB charging, Type-C charging, and wireless charging), and can charge three mobile phones or other mobile devices at the same time. At the same time, the storage box has a semi-open design, which makes it easy for the operator to put in and take out the phone. When the phone is inserted into the storage box 2 through the placement slot 135, the spring-loaded part 311 of the silicone component presses the phone and fixes it. When the phone is placed in the storage box, it will be firmly fixed when it encounters a bumpy road or sudden braking, ensuring that the phone will not be thrown out, effectively preventing the phone from shifting or polarizing during driving, which may cause charging failure or damage.
