[0002] With the rapid development of the automotive industry, in-car entertainment systems have gradually become an indispensable part of car configuration. In traditional micro-cars, due to cost and space constraints, many vehicles are not equipped with central control systems. The power amplifiers used in these micro-cars usually lack Bluetooth capabilities and cannot connect to the user's mobile phone via Bluetooth, making it impossible to play music through the phone.

[0003] Currently, some vehicles on the market have addressed this issue by installing in-car MP5 players. These players typically have built-in Bluetooth amplifiers that connect to mobile phones via Bluetooth, enabling wireless audio transmission and playback. However, the high cost of in-car MP5 players makes them unaffordable for traditional minicars, hindering their widespread adoption. Consequently, minicar owners face significant limitations in enjoying convenient in-car entertainment.

[0004] In addition, since the car's Bluetooth amplifier is installed below the car's air-conditioning output pipe, there is a risk of water dripping from the air-conditioning pipe onto the Bluetooth amplifier during use, causing the risk of water leakage and damage to the Bluetooth amplifier.

[0005] In this context, the market urgently needs to develop and design a low-cost car-mounted Bluetooth amplifier that can connect to mobile phone Bluetooth and automatically divert dripping air-conditioning water to meet the needs of micro-car owners. Utility Model Content

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0028] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] To achieve the above purpose, the embodiment of the present utility model provides a car-mounted Bluetooth amplifier that prevents air conditioning from dripping, referring to Figure 1-7 As shown, it includes a bottom shell, a heat dissipation back plate, a cover plate, an antenna box, a Bluetooth antenna group, power amplifier components and a main control board. The rear end face of the bottom shell is provided with a heat dissipation back plate, the bottom shell is provided with a cover plate, and the cover plate is provided with a drainage groove group for air conditioner dripping. A mounting hole is provided on one side of the bottom shell, and the upper and lower edges of the inner side of the mounting hole are integrally connected and are provided with folded edge pieces. The antenna box is sleeved in the mounting hole, and the upper and lower edges of the antenna box are integrally connected and are provided with outward-facing inverted parts, and the inverted parts are tightly buckled with the folded edge pieces. The inner side of the antenna box is provided with a Bluetooth antenna group, and the other side of the bottom shell is provided with power amplifier components. The inner side of the bottom shell is provided with a main control board, and the main control board is electrically connected to the Bluetooth antenna group and the power amplifier components.

[0030] If the power amplifier of a traditional microcar is equipped with a car MP5 machine with Bluetooth function, the cost of the traditional microcar will inevitably increase, which will cause certain promotion resistance to the adaptation of the power amplifier with Bluetooth function in the microcar. Therefore, in this embodiment, in order to adapt to the compatibility of functions and costs of the microcar, an antenna box and a Bluetooth antenna group are added to one side of the bottom shell, which can enhance the Bluetooth signal and can also be used to connect to the mobile phone of the owner in the cab by Bluetooth, so that the power amplifier of the microcar has the Bluetooth function of the traditional high-cost car MP5 machine, and can also greatly reduce the manufacturing cost of the entire power amplifier. The most important thing is that the power amplifier of this embodiment can meet user needs in microcars and be further promoted and popularized.

[0031] refer to Figure 5-7As shown, the folded edge piece is folded at a 90-degree angle, and the undercut portion is horizontal. The antenna box is inserted into the mounting hole. First, the undercut portion and the folded edge piece are pressed against each other and inserted. After the undercut portion completely exceeds the folded edge piece, the undercut portion is tightly pressed against the folded edge piece, so that the antenna box is fixed on the bottom shell, and the outer surface of the antenna box and the outer side surface of the bottom shell are flat; of course, on this basis, a seven-shaped top piece piece can also be integrally connected on the front and back sides of the mounting hole. For example, the seven-shaped top piece piece after being bent twice can be used to press against the inner side surface of the antenna box. In this way, the seven-shaped top piece piece serves to limit the antenna box from falling into the bottom shell, and the folded edge piece serves to limit the antenna box from falling out of the bottom shell, so that the entire antenna box is fastened to the mounting hole, and the Bluetooth antenna group connected to the antenna box is securely and firmly installed to ensure the stability of Bluetooth use.

[0032] Furthermore, the Bluetooth antenna assembly includes an antenna panel and an antenna band. The antenna panel is attached to the inner side of the antenna box. One end of the antenna band is integrally connected to the antenna panel, and the other end of the antenna band is provided with a connector for connecting to the main control board. Because the antenna box is installed near the driver's seat, the Bluetooth signal is the strongest, ensuring a reliable and stable Bluetooth connection to the driver's mobile phone. This significantly reduces the cost of equipping a mini-car with a Bluetooth-enabled amplifier, meeting the diverse needs of users.

[0033] Among them, reference Figure 1-2 As shown, the drainage trough group includes an annular trough and a drainage trough. An annular trough is provided on the upper surface of the cover plate. Two drainage troughs are provided on one side of the cover plate. The two drainage troughs are evenly connected to the annular trough. A first loading bracket is provided in the middle of one side of the bottom shell, and a second loading bracket is provided in the middle of the heat dissipation back plate. The first loading bracket has the same orientation as the drainage trough.

[0034] In this embodiment, due to the requirements of the driving position and visual viewing, the power amplifier is installed at an angle. By setting a first loading bracket and a second loading bracket, the entire power amplifier is tilted, and the drainage groove is located below the annular groove, so that the collected water droplets are gathered in the annular groove and discharged through the drainage groove, which will not affect the use of the power amplifier and will not cause water leakage and damage.

[0035] Among them, reference Figure 3-4 As shown, a plurality of heat dissipation holes are provided on the side of the bottom shell, a connection plug-in is provided on one side of the power amplifier component, and the heat dissipation back plate is made of aluminum profile. The heat dissipation back plate and heat dissipation holes of the aluminum profile further discharge the temperature inside the bottom shell, thereby reducing the temperature inside the bottom shell.

[0036] In summary, the present invention provides a car-mounted Bluetooth amplifier that prevents air conditioning from dripping. By arranging an antenna box and a Bluetooth antenna group on the side of the bottom shell close to the driver's seat, the antenna panel and the antenna band are connected, which can release a strong Bluetooth signal for the owner's mobile phone to connect. Only a small improvement is needed to avoid the high cost of traditional car-mounted MP5 car machines, and Bluetooth connection with the owner's mobile phone can be achieved, which greatly reduces the cost and promotes the further popularization of micro-cars. By arranging a drainage groove group on the cover plate, after water droplets fall onto the upper surface of the upper cover plate of the air conditioner above it, the amplifier needs to be installed at an angle due to the viewing requirements of the cab, and the dripping water droplets will naturally gather in the preset annular groove and flow out from the drainage groove to the lower part of the amplifier, avoiding infiltration into the amplifier and affecting its use.

[0037] The above description of the technical principles of the present invention in conjunction with specific embodiments is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the principles of the present invention fall within the scope of protection of the present invention. Those skilled in the art can easily conceive of other specific embodiments of the present invention without inventive effort, and all of them fall within the scope of protection of the present invention.
