Description

Technical Field

[0001] The present invention relates to the field of automobiles, and in particular to an adapter socket for automobiles. Background Art

[0002] With the increasing popularity of automobiles, the demand for car modifications is also increasing, especially for passenger cars. After purchasing a car, many users believe that the original configuration is not enough to meet their needs and often modify the car (commonly known as "aftermarket"), such as adding or modifying the navigation system, audio system, and reversing camera system.

[0003] To achieve car after-sales installation, you first need to lead out car control signals from the vehicle, such as horn signals, steering wheel learning signals, ACC key switch signals, low light detection signals, automatic antenna power signals, reversing detection signals and ground signals GND and power positive signals, as well as reversing image video signals (the original car has a reversing image function), AUX (external audio source) signals and USB signals, etc.; in addition, there are car data signals (original car data), such as original car radar, vehicle function settings and driving computer data signals.

[0004] Existing vehicles are generally equipped with a control signal output terminal, including one or more plugs. A socket that matches the plug is required for after-installation. These plugs are inserted into the socket, and then the wiring harness and wires are led out of the socket, including a wiring harness connected to the 16-pin (16-pin) public plug. The 16-pin public plug is a common plug in the industry, which is used to lead out horn signals, steering wheel learning signals, ACC key switch signals, small light detection signals, automatic antenna power signals, reversing detection signals and ground signals GND and power positive signals. The 16-pin public plug can be matched with the 16-pin public socket on the after-installed navigation host to input the signals led out from the control signal output terminal to the after-installed navigation host. Of course, if any of these signals need to be decoded, they also need to be decoded and input into the after-installed navigation host through the 16-pin public socket.

[0005] In addition to the signals transmitted by the above-mentioned 16-pin public plug, the existing socket is also connected to wires that output reversing image signals, AUX (external audio source) signals and USB signals. The other ends of these wires are connected to plugs, which can be inserted into the corresponding sockets on the after-installed navigation host to transmit the corresponding signals to the after-installed navigation host.

[0006] Vehicle data signals that require decoding are typically transmitted via a wiring harness to a decoding protocol box for decoding, and are then transmitted via the following communication methods: CAN (Controller Area Network) bus, LIN (Local Interconnect Network), MOST (Media Oriented System Transport), in-vehicle Ethernet, and IEBUS (Inter Equipment Bus). In the prior art, vehicle data signals are typically first drawn from the vehicle's signal output terminal via a wiring harness, then input via a plug into a decoding box with decoding capabilities (referred to in the industry as a "protocol box"). The protocol box decodes the original vehicle data and then outputs the decoded data to an expansion slot on the adapter socket. The expansion slot then transmits the data to an aftermarket navigation head unit via a plug and wiring harness. This is also how the vehicle data signals output by the aftermarket navigation head unit are transmitted to the vehicle.

[0007] In addition, in addition to the control signals drawn from the car itself, if the original car is not equipped with it, some vehicles will be equipped with some external devices during modification, such as rear-view video equipment, right-view video equipment, 360 panoramic video equipment, modified USB, wifi antenna, Bluetooth antenna, GPS / Beidou positioning equipment, and equipment for receiving mobile communication signals, such as 3G / 4G / 5G antennas, etc. These external devices are usually directly connected to the after-installed navigation host through wires or wiring harnesses to achieve signal transmission.

[0008] Therefore, the tail end of the existing automotive control signal adapter socket is inevitably connected to a large number of wiring harnesses and wires, which connect to the protocol box and aftermarket navigation system through these wiring harnesses and wires. In addition, external devices are also connected to the aftermarket navigation system through wiring harnesses and wires. These wiring harnesses and wires are not only expensive, take up space, and are inconvenient to install and remove, but also pose the risk of short circuits caused by the wiring harnesses and wires. Summary of the Invention

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0033] The control signals drawn from the car can be divided into three types: one is the signal that does not need to be decoded, such as the horn signal, automatic antenna power signal, ground signal GND and power positive signal. These signals do not need to be decoded after being drawn from any brand and model of vehicle, and are referred to as "non-decoded car control signals" in the embodiment of this application; the other is the signal that needs to be decoded, usually called car data signal (original vehicle data signal), such as steering wheel buttons, original vehicle radar, vehicle function settings and on-board computer data, etc., which need to be decoded after being drawn from any brand and model of vehicle, and are referred to as "car data signals" in the embodiment of this application; other signals are signals that may need to be decoded. They need to be decoded on some brands and models of vehicles, but may not need to be decoded on other brands and models of vehicles.

[0034] See also Figure 1 、 Figure 2 and Figure 3 , Figure 1 A three-dimensional diagram of a car adapter socket is provided for an embodiment of the present application. Figure 2 This is a left side view of the automotive adapter socket according to an embodiment of the present application. Figure 3 The bottom view of the automotive adapter socket according to the embodiment of the present application is shown in FIG. The automotive adapter socket according to the embodiment of the present application comprises a base 01 , an adapter and decoding circuit board 02 , and a composite output plug 03 .

[0035] The shape of base 01 matches the plug at the vehicle's control signal output terminal, which can be inserted into a groove on base 01. Base 01 is equipped with pins that mate with the vehicle's control signal input plug. These pins, in conjunction with the vehicle's control signal output plug, allow the vehicle's control signals to be output. Different brands and models of vehicles may use different control signal output terminals. The shape, structure, and pin arrangement of base 01 are not limited, as long as they can mate with the vehicle's control signal output plug.

[0036] like Figure 1 、 Figure 2 and Figure 3 As shown, the adapter and decoder circuit board 02 is mounted directly on the base 01, with its input connected to the pins on the base 01 via welding, crimping, or other connection methods. The adapter and decoder circuit board 02 can be a printed circuit board. The input of the printed circuit board connects to the pins on the base 01, receiving the vehicle control signals from the vehicle control signal output. The input of the printed circuit board is designed based on the pin layout of the base 01.

[0037] A composite output plug 03 is directly provided on the adapter and decoding circuit board 02. The composite output plug 03 is connected to the adapter and decoding circuit board 02 by welding, crimping or other means. The composite output plug 03 can be set on the adapter and decoding circuit board 02 with its back facing the base 01 (the two sides of the adapter and decoding circuit board 02 are set separately from the base 01).

[0038] Figure 4 This is a schematic diagram of a composite output plug 03 according to an embodiment of the present application. In this embodiment, a 41-pin composite output plug 03 is used as an example. Of course, when applying the technical solutions of this embodiment, composite output plug 03 can also be a 41-pin plug, a 60-pin plug, or a plug with a greater or fewer pins. The pin number corresponds to the number of control signals to be transmitted to the aftermarket navigation host, so as to meet the vehicle's control signal transmission requirements.

[0039] like Figure 5As shown, Figure 5 Schematic diagram of the switching and decoding circuit board 02 according to an embodiment of the present application. In this embodiment of the present application, the switching and decoding circuit board 02 is divided into two functional areas: a signal switching functional area 021 and a signal decoding functional area 022. The signal decoding functional area 022 integrates a decoding chip and corresponding circuits.

[0040] After receiving the vehicle control signal, the switching and decoding circuit board 02 processes two different types of vehicle control signals separately. One part is "non-decoding vehicle control signals", such as horn signals, automatic antenna power signals, ground signals GND, power positive signals, reversing image video signals, AUX (external audio source) signals and USB signals, etc.; of course, there are other signals that do not need to be decoded on some brands and models of cars and also belong to this category, such as one or more of the steering wheel learning signals, ACC key switch signals, small light detection signals and reversing detection signals.

[0041] After receiving the undecoded vehicle control signal via the signal transfer function area 021, the transfer and decoding circuit board 02 directly outputs it to the aftermarket navigation system through the composite output plug 03. Of course, as technology advances, new control signals that do not require decoding will emerge. Any signal that does not require decoding and is directly input to the aftermarket navigation system will be considered an undecoded vehicle control signal as defined in this application.

[0042] For vehicle data signals requiring decoding, such as those from steering wheel buttons, vehicle radar, vehicle function settings, and trip computer data, as well as other control signals on some car brands and models that require decoding, such as one or more of the following: steering wheel learning signals, ACC key switch signals, low-beam detection signals, and reverse detection signals, the transfer and decoding circuit board 02 receives these signals through the signal decoding function area 022 and decodes them using the decoding chip integrated therein. The decoded vehicle data signals are also output through the composite output plug 03.

[0043] Correspondingly, the aftermarket navigation system is equipped with a composite socket that mates with the composite output plug. The shape and structure of this composite socket correspond to composite output plug 03, and composite output plug 03 can be directly inserted into the composite socket on the aftermarket navigation system. Both the previously undecoded vehicle control signals and vehicle data signals can be transmitted to the aftermarket navigation system via the composite output plug.

[0044] In addition, if Figure 6 As shown, Figure 6The adapter socket with an extension interface provided in the embodiment of the present application. The adapter socket provided in the embodiment of the present application can also be provided with an extension interface 05 at its input end to receive signals transmitted by an additional external device (hereinafter referred to as "external device control signals"), such as rear-view video signals, right-view video signals, 360 panoramic video signals, modified USB signals, wifi antenna signals, Bluetooth antenna signals, GPS / Beidou signals, and mobile communication signals, such as 3G / 4G5G signals. After the extension interface 05 receives the external device control signal, it is output to the after-installed navigation host through the composite output plug 03 on the adapter and decoding circuit board 02. Accordingly, the after-installed navigation host no longer needs to be separately provided with an interface for receiving external device control signals, but these interfaces are integrated into the composite slot. In this way, after the external device control signal is transmitted to the adapter socket provided in the embodiment of the present application, it does not need to be transmitted to the after-installed navigation host through a wire or a wiring harness. The signal transmission can be achieved by cooperating with the adapter socket provided in the embodiment of the present application and the slot on the after-installed navigation host.

[0045] The adapter socket provided in this embodiment has an adapter and decoding circuit board 02 mounted directly on its base 01. This circuit board 02 transmits undecoded vehicle control signals directly to the aftermarket navigation system via a composite output plug 03. It also decodes received vehicle data signals, which are then transmitted to the aftermarket navigation system via the composite output plug. External device control signals can also be uniformly received by this circuit board 02 and transmitted to the aftermarket navigation system via the composite output plug 03. This approach addresses the high cost, inconvenient assembly and disassembly, and safety risks associated with existing automotive adapter sockets.

[0046] The above describes in detail the automotive adapter socket provided in the embodiments of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is intended only to facilitate understanding of the present application. Furthermore, those skilled in the art will appreciate that variations in the specific implementation methods and scope of application may occur based on the principles of the present application. In summary, the contents of this specification should not be construed as limiting the present application.
