Description

Technical Field

[0001] This utility model relates to transmitters, and more particularly to a vehicle-mounted Bluetooth transmitter. Background Technology

[0002] A car Bluetooth transmitter is a built-in component that enables older cars without Bluetooth, USB, or CarPlay to have wireless music and hands-free calling capabilities.

[0003] While existing in-vehicle Bluetooth transmitters achieve basic functions, their cylindrical shape necessitates vertical placement, which can obstruct adjacent 12V or USB ports, preventing them from being shared. Furthermore, they rely entirely on the 12V power supply to shut down immediately after the engine is turned off, and the loss of FM frequency settings or pairing information can easily lead to driver distraction.

[0004] Therefore, there is a particular need for an in-vehicle Bluetooth transmitter to address the problems existing in the current technology. Utility Model Content

[0005] To overcome the shortcomings of existing in-vehicle Bluetooth transmitters, such as their cylindrical shape, vertically occupying the plug hole and blocking adjacent 12V or USB ports, making them unusable, their complete reliance on the 12V plug for immediate shutdown after engine shutdown, and the risk of driver distraction due to loss of FM frequency settings or pairing information, the technical problem to be solved is to provide an in-vehicle Bluetooth transmitter.

[0006] Technical Solution: A vehicle-mounted Bluetooth transmitter includes a plug, a cover, a limiting ring, a USB interface, an audio cable, a first magnetic ring, a second magnetic ring, a housing, a Bluetooth transmission module, a mounting bracket, a positive electrode plate, a negative electrode plate, a display screen, a control motherboard, and buttons. The plug has a cover at its front, with a limiting ring embedded in the front of the cover. A USB interface is embedded in the upper front of the cover, electrically connected to the plug. An audio cable is located in the middle of the front of the cover, electrically connected to the plug. A first magnetic ring is located at the upper end of the audio cable, and a second magnetic ring is attracted within the first magnetic ring. The second magnetic ring has a housing at its top, and a mounting bracket is fixed to the rear of the housing. A negative electrode is embedded on the left side of the mounting bracket, and a positive electrode is embedded on the right side of the mounting bracket. Both the negative and positive electrodes are electrically connected to the plug. A display screen is installed between the upper parts of the negative and positive electrodes. A control motherboard is located at the lower front of the display screen and is electrically connected to the display screen. A Bluetooth transmission module is embedded in the front of the housing and is electrically connected to the control motherboard. There are sliding buttons on both the left and right sides of the front of the housing. There are at least two buttons, and both buttons are electrically connected to the control motherboard.

[0007] Furthermore, it also includes LED lights, with LED lights symmetrically installed in the middle of the front of the casing, and the LED lights are electrically connected to the control motherboard.

[0008] Furthermore, it also includes a battery, which is embedded in the rear of the casing and electrically connected to the control motherboard.

[0009] Furthermore, it also includes a shaped frame, a first winding frame and a second winding frame. The shaped frame is connected between the left side of the outer wall of the outer shell and the left side of the outer wall of the mounting frame. There is at least one shaped frame. The first winding frame is welded to the upper part of the shaped frame, and the second winding frame is welded to the lower part of the shaped frame. The inner sides of the first winding frame and the second winding frame are in contact with each other.

[0010] Furthermore, it also includes a rotating rod, a round rod, and a suction cup. The rotating rod is rotatably mounted at the rear of the mounting bracket, and a round rod is mounted on the rotating rod. A suction cup is mounted at the rear of the round rod.

[0011] Furthermore, it also includes an electret microphone, with the electret microphone mounted in the middle of the front side of the mounting bracket.

[0012] The beneficial effects are: 1. With the cooperation of components such as the plug, cover plate and SB interface, the car radio can be received and played when tuned to the same frequency, and the positive and negative electrodes can be displayed in real time on the display screen.

[0013] 2. This utility model uses components such as an irregularly shaped frame, a first winding frame, and a second winding frame to work together. People can wind data cables onto the first winding frame and the second winding frame. The irregularly shaped frame provides support, and the first winding frame and the second winding frame work together to wind up the data cable.

[0014] 3. With the cooperation of components such as a battery, the vehicle Bluetooth transmitter does not need to rely on the power generated by the plug and cigarette lighter, so the vehicle Bluetooth transmitter can be used normally when the power is off. Attached Figure Description

[0026] When users need to use the car Bluetooth transmitter, they first insert the plug 1 into the cigarette lighter socket. After the cigarette lighter and plug 1 are powered on, the built-in Bluetooth transmission module 9 (commonly JLAC6966, CSR series) operates in the 2.4GHz ISM band and broadcasts the device name. After the mobile phone searches for and pairs with the transmitter, an A2DP (stereo audio) and HFP (hands-free calling) link is established, wirelessly transmitting music or voice calls to the transmitter. Users control the mainboard 13 via button 14 to convert the received digital audio using a DAC, thus obtaining analog audio. If the analog audio is sent to the FM channel, it is then fed into a frequency modulation chip (QN8027, BK1080, etc.) for frequencies between 76–108MHz. Frequency modulation (FM) is performed at a fixed frequency to form an radio frequency signal. If the signal is routed through the AUX channel, the analog audio is directly output through the 3.5m port. In FM mode, the FM signal with a radio frequency power of 0–10dBm is radiated through the PCB microstrip antenna or the headphone ground wire. The car radio can be received and played by tuning to the same frequency. The positive electrode 11 and the negative electrode 1101 can display their status in real time on the display screen 12. The mounting bracket 10 and the outer shell 8 provide support. When the first magnetic ring 6 and the second magnetic ring 7 are attracted together, the second magnetic ring 7 will fix the outer shell 8. The first magnetic ring 6 stops contacting the second magnetic ring 7, and the limiting ring 3 limits the audio cable 5. The audio cable 5 is covered with foldable elastic plastic, which effectively improves the toughness of the audio cable 5 during folding. At the same time, users can connect the charging cable to the USB interface 4 as needed, and the outer shell 8 will stop being fixed to the audio cable 5. In this way, users can move the car Bluetooth transmitter to a designated position as needed. The control motherboard 13 will indicate whether it is working through the LED light 15. The battery 16 can provide power to the control motherboard 13 and the display screen 12, so that the car Bluetooth transmitter does not need to be powered by the battery. Relying on the power generated by the plug 1 and the cigarette lighter, the car Bluetooth transmitter can be used normally even when the power is off. When people need to wind up the data cable, they can wind the data cable onto the first winding frame 18 and the second winding frame 19. The irregular frame 17 provides support. The first winding frame 18 and the second winding frame 19 work together to wind up the data cable. People can rotate the suction cup 22 as needed. The rotation of the suction cup 22 will cause the round rod 21 to rotate. The rotation of the round rod 21 will cause the rotor to move adaptively. When the suction cup 22 comes into contact with the car parts, the suction cup 22 will be attached to the car parts. The electret microphone 23 works with the control motherboard 13 to absorb the voice spoken by people, thus making the car Bluetooth transmitter more intelligent.
