Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobiles, and in particular to a switching socket for automobiles. BACKGROUND

[0002] With the popularity of automobiles, the demand for automobile modification is also increasing, especially for passenger cars. Many users after purchasing a car think that the original configuration is not enough to meet their own needs, and often modify the car (industry commonly known as "aftermarket") such as adding or modifying navigation systems, sound systems, and reversing image systems.

[0003] To implement the automobile aftermarket, first, the automobile control signals need to be led out from the vehicle, such as the horn signal, steering wheel learning signal, ACC key switch signal, small light detection signal, automatic antenna power signal, reversing detection signal, ground signal GND and power positive signal, and reversing image video signal (original car with reversing image function), AUX (external sound source) signal and USB signal, etc. In addition, there are data signals that need to be transmitted to the decoding protocol box for decoding, such as CAN (Controller Area Network) bus signal, LIN (Local Interconnect Network) signal, MOST (Media Oriented System Transport) signal, vehicle-mounted Ethernet signal and IEBUS (Inter Equipment Bus) signal, etc. A control signal output end is generally provided on the existing vehicle, including one or more plugs. When aftermarket, a socket cooperating with the plug is needed, the plug is inserted into the socket, and then a wire harness and a lead wire are led out from the socket, including a wire harness connected with a 16-pin male plug. The 16-pin male plug is a commonly used plug in the industry, which is used to lead out the horn signal, steering wheel learning signal, ACC key switch signal, small light detection signal, automatic antenna power signal, reversing detection signal, ground signal GND and power positive signal. The 16-pin male plug can cooperate with the 16-pin female socket on the aftermarket navigation mainframe to input the signals led out from the control signal output end into the aftermarket navigation mainframe.

[0004] In addition to the 16-pin male plug transmitted signals described above, the existing socket is also connected with the output reverse image signal, AUX (external audio source) signal and USB signal wires, the other end of the wires is connected with the plug, which can be inserted into the corresponding socket of the rear-mounted navigation host to transmit the corresponding signals to the rear-mounted navigation host. Other signals such as CAN bus signal, LIN signal, vehicle Ethernet signal and IEBUS signal are usually input through a plug to a decoding box (industry called "protocol box") with decoding function, and the original vehicle data is decoded by the protocol box, such as steering wheel key, original vehicle radar, vehicle function setting and driving computer data.

[0005] Therefore, the tail end of the existing automobile control signal lead-out socket will inevitably be connected with a large number of lines and wires, which are connected with the protocol box and the rear-mounted navigation host through these wire harnesses and wires. These wire harnesses and wires are not only high in cost, occupy space and inconvenient to install and remove, but also have the natural risk of short circuit caused by wire harnesses and wires. SUMMARY

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0029] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 The perspective view of the adapter socket for automobile provided by the embodiment of the present application, Figure 2 The left view of the adapter socket of the embodiment of the present application, Figure 3 The bottom view of the adapter socket of the embodiment of the present application. The adapter socket for automobile provided by the embodiment of the present application comprises a base 01, an adapter circuit board 02, a 16-pin male plug 03 and an expansion slot 04.

[0030] The shape of the base 01 matches the plug of the automobile control signal output end, and the plug of the automobile control signal input end can be inserted into the groove of the base 01. The base 01 is provided with a pin that matches the plug of the automobile control signal input end. Through the cooperation of the pin and the plug of the automobile control signal output end, the automobile control signal can be led out. The shape and structure of the base 01 and the arrangement of the pin are not limited, as long as they can match the plug of the automobile control signal output end.

[0031] As shown in Figure 1 , Figure 2 and Figure 3 , the adapter circuit board 02 is arranged on the base 01, and the input end thereof is connected with the pin on the base 01 through welding, pressure connection or other connection modes. The adapter circuit board 02 can adopt a printed circuit board, which is referred to as a “first printed circuit board” in the embodiment. The input end of the first printed circuit board is connected with the pin of the base 01, and receives the automobile control signal led out from the automobile control signal output end. The input end of the first printed circuit board is designed according to the arrangement of the pin of the base 01.

[0032] The output end of the first printed circuit board can be designed into two areas, forming a general layout: a 16-pin male plug area and an expansion slot area. The 16-pin male plug area is used to set the 16-pin male plug 03. The 16-pin male plug 03 is welded, crimped or connected by other means on the 16-pin male plug area, and can be set on the first printed circuit board facing away from the base 01 (separately set on the two sides of the first printed circuit board), and matched with the 16-pin female socket on the rear-mounted navigation main machine. When the 16-pin male plug is inserted into the 16-pin female socket on the rear-mounted navigation main machine, the automobile control signal can be directly transmitted to the rear-mounted navigation main machine without wire or wire harness. The circuit diagram of the general 16-pin male plug in the industry is shown in Figure 4 The signals input to the rear-mounted navigation main machine include 8 horn signals, 2 steering wheel learning signals, 1 ACC key switch signal, 1 small light detection signal, 1 automatic antenna power signal, 1 reverse detection signal, and 1 ground signal GND and power positive B+ signal. Of course, it can be foreseen that with the development of automobile rear-mounted technology, the signals transmitted by the 16-pin male plug may change. The layout of the 16-pin male plug and the transmitted signals in the present application embodiment can also be adaptively adjusted according to the development of technology.

[0034] In addition, as shown in Figure 5 If it is necessary to decode the original vehicle data, a decoding circuit board 05 can also be welded, crimped or connected by other means on the adapter circuit board, used to decode steering wheel key data, original vehicle radar data, vehicle function setting data and driving computer data, etc. The decoding circuit board 05 can also be a printed circuit board, which is referred to as a "second printed circuit board" in the present embodiment. The adapter circuit board 02 outputs the automobile data signals from the automobile control signal output end to the adapter circuit board 02, and the output end of the adapter circuit board 02 outputs the automobile data signals to the decoding circuit board 05. The decoding circuit board 05 decodes the automobile data and transmits it back to the adapter circuit board 02. The adapter circuit board 02 can transmit the decoded automobile data to the rear-mounted navigation main machine through the expansion slot 04. The rear-mounted navigation main machine can also output corresponding signals to the decoding circuit board 05, and the decoding circuit board 05 transmits the signals to the adapter circuit board 02, and the adapter circuit board 02 transmits the signals back to the automobile.

[0035] In the embodiment, the decoding circuit board 05 is directly arranged on the adapter circuit board 02, and a wire harness is not needed to lead out the automobile data signal from the socket to the protocol box.

[0036] The adapter socket provided in the embodiment directly arranges the adapter circuit board 02 on the base 01 of the adapter socket, directly arranges the 16-pin male plug 03 and the expansion slot 04 on the adapter circuit board 02, plugs the 16-pin male plug 03 with the socket on the rear-mounted navigation main machine, and realizes direct transmission of the automobile control signal. In addition, the decoding circuit board 05 can be directly arranged on the adapter circuit board 02 to analyze the automobile data. The problems of high cost, inconvenient installation and removal, and safety risk of the existing adapter socket for automobiles can be solved.
