[0040] See also Figure 2 , the vehicle electronic device is used for the vehicle body 1, that is, the vehicle electronic device can be installed on the vehicle body 1. The vehicle electronic device includes a switching device, an internal device 2 arranged inside the vehicle body 1, and an external device 3 arranged outside the vehicle body 1. The internal device 2 includes a first wire 22 and an internal device body 21 electrically connected to the first wire 22, and the external device 3 includes a second wire 32 and an external device body 31 electrically connected to the second wire 32, and the first wire 22 and the second wire 32 are respectively connected to the switching device. Among them, the internal device body 21 is used to provide power, for example, the internal device body 21 is a battery. The external device body 31 is used to receive power and is used to achieve specific functions, for example, the external device body 31 is a frequency jammer, a communication antenna module, a radio frequency module, etc. It can be understood that in some other embodiments, the internal device body 21 can also be used to receive power, such as a battery. The external device body 31 can also be used to provide power, such as a vehicle-mounted solar panel. In this embodiment, the external device body 31 is a frequency jammer.

[0041] See also Figure 3 The adapter device is used for a vehicle electronic device, and the adapter device includes a flexible circuit board 4 and two adapter modules 5, wherein one adapter module 5 is arranged outside the vehicle body 1 and connected to the external device 3, and the other adapter module 5 is arranged inside the vehicle body 1 and connected to the internal device 2, and the two ends of the flexible circuit board 4 are electrically connected to the two adapter modules 5 respectively. The first wire 22 is electrically connected to the adapter module 5 located inside the vehicle body 1, and the second wire 32 is electrically connected to the adapter module 5 located outside the vehicle body 1.

[0042] See also Figure 4 The adapter module 5 is used to electrically connect the wire to the flexible circuit board 4. The adapter module 5 includes: a housing 51, a first connector 52 and a wire connection unit 53. The first connector 52 and the wire connection unit 53 are both arranged in the housing 51, and the first connector 52 is electrically connected to the wire connection unit 53. Among them, the first connector 52 is used to connect to the flexible circuit board 4, and the wire connection unit 53 is used to connect to the wire, so that the electrical signal can be transmitted between the flexible circuit board 4, the first connector 52, the wire connection unit 53 and the wire.

[0043] Among them, the electrical signal is, for example, a signal or power supply, the signal is a regular electrical signal with information (such as a clock signal, a data signal), and the power supply is used to provide electrical energy, such as direct current or alternating current. The conductor refers to a specific wire or cable (here, for example, the first conductor 22 and the second conductor 32), and the conductor transmission is, for example, the transmission of a signal or power supply, and the specific type of the conductor is, for example, a signal cable and a power cable. For example, taking the electrical signal transmission path between the internal device body 21 and the flexible circuit board 4 as an example, one end of the first conductor 22 is electrically connected to the conductor connection unit 53 of the internal adapter module 5, and the other end of the first conductor 22 is electrically connected to the internal device body 21, and the conductor connection unit 53 is electrically connected to the first connector 52, and the first connector 52 is connected to one end of the flexible circuit board 4. If the internal device body 21 is used to provide power, the power supply of the internal device body 21 can be transmitted to the conductor connection unit 53 of the internal adapter module 5 through the first conductor 22, and then transmitted to the first connector 52 through the conductor connection unit 53, and the first connector 52 is transmitted to the flexible circuit board 4, so that the power supply in the conductor transmission can be converted into transmission in the flexible circuit board 4.

[0044] Therefore, the adapter module provided in this embodiment can establish a signal transmission path between the flexible circuit board 4 and the wire, so that the flexible circuit board 4 and the wire can transmit electrical signals normally. In addition, the flexible circuit board 4 is a circuit board with high flexibility and adaptability, which can provide circuit connections in devices of various shapes and sizes. For example, the flexible circuit board 4 penetrates the vehicle body 1 without affecting the outer shell structure of the vehicle body 1.

[0045] In some embodiments, Figure 4 As shown, the wire connection unit 53 includes an adapter plate 531 and a voltage connector 532 integrated on the adapter plate 531. The first connector 52 is provided on the adapter plate 531. The voltage connector 532 is used to connect to the wire. The voltage connector 532 is connected to the first connector 52 through the power line. The power transmitted by the adapter module 5 can be a high-voltage power supply (220V and above). The high-voltage power supply is connected through the voltage connector 532, which can ensure that the high-voltage power supply is safely and reliably transmitted from the first wire 22 to the flexible circuit board 4, and that the high-voltage power supply is safely and reliably transmitted from the flexible circuit board 4 to the second wire 32. Or ensure that the high-voltage power supply is safely and reliably transmitted from the second wire 32 to the flexible circuit board 4, and ensure that the high-voltage power supply is safely and reliably transmitted from the flexible circuit board 4 to the first wire 22. The power line includes a live wire and a neutral wire, and a spacing is provided between the live wire and the neutral wire to prevent high voltage breakdown. Among them, the power line diagram is not shown, and the first connector 52 and the voltage connector 532 are integrated on the adapter plate 531, which can be easily disassembled.

[0046] In some embodiments, the wire connection unit 53 also includes a CAN connector 533 and a signal connector 534, and the CAN connector 533 and the signal connector 534 are integrated on the adapter board 531. The CAN connector 533 is electrically connected to the first connector 52 through a bus line, and the signal connector 534 is electrically connected to the first connector 52 through a signal line. The CAN connector 533 is mainly used to transmit data based on the CAN protocol, and the signal connector 534 is mainly used to transmit various types of signals. Specifically, the CAN connector 533 and the signal connector 534 are used to convert the signal transmitted by the flexible circuit board 4 into a conventional cable signal for transmission, or to convert the conventional cable signal transmitted by the first wire 22 into a signal transmitted by the flexible circuit board 4 for transmission. Among them, the bus line and the signal line are not shown in the figure. The CAN connector 533 and the signal connector 534 are integrated on the adapter board 531 to form an integral structure with the first connector 52 and the voltage connector 532, which can be easily disassembled.

[0047] In some embodiments, Figure 4 As shown, the housing 51 includes a first housing 511 and a second housing 512 connected to the first housing 511, and at least one of the first housing 511 and the second housing 512 is provided with a sealing member 54. Specifically, the sealing member 54 can be provided on the first housing 511 or the second housing 512, or can be provided on the first housing 511 and the second housing 512 respectively. The sealing member 54 can be provided in the form of a sealing ring. For example, the first housing 511 is provided with a sealing member 54, and the sealing member 54 is specifically provided at the end position opposite to the first housing 511 and the second housing 512 and is fixedly connected to the first housing 511. When the first housing 511 is connected to the second housing 512, the sealing member 54 first seals and abuts against the second housing 512. Due to the presence of the flexible circuit board 4, the sealing member 54 and the second housing 512 clamp the flexible circuit board 4 between them, that is, the sealing member 54 presses against one side of the flexible circuit board 4, and the second housing 512 presses against the opposite side of the flexible circuit board 4, thereby achieving the clamping and sealing of the flexible circuit board 4. For example, when both the first shell 511 and the second shell 512 are provided with a seal 54, the seal 54 of the first shell 511 and the seal 54 of the second shell 512 are pressed against the two sides of the flexible circuit board 4 respectively, and the flexible circuit board 4 is clamped and sealed at the same time. It can be understood that the seal 54 is used to fix the flexible circuit board 4 and can also achieve sealing. The seal 54 can be selected to be a soft rubber material, for example, the seal 54 is an elastic gasket, which can achieve sealing and fix the flexible circuit board 4 without damaging the flexible circuit board 4.

[0048] In some embodiments, at least one wire hole 513 for the wire to be inserted is provided on the first shell 511 and / or the second shell 512. The wire hole 513 is used to allow the wire to pass through and extend into the interior of the shell 51 to connect with the wire connection unit 53. The number of wire holes 513 is set according to actual needs.

[0049] In some embodiments, see also Figure 5 , the flexible circuit board 4 includes a flexible circuit board body 41 and a second connector 42, the second connector 42 is arranged at one end of the flexible circuit board 4, and the first connector 52 is used to connect with the second connector 42. It can be understood that there are two second connectors 42, and the two second connectors 42 are respectively arranged at both ends of the flexible circuit board 4. Among them, one second connector 42 is electrically connected to the first connector 52 of the adapter module 5 arranged outside the vehicle body 1, and the other second connector 42 is electrically connected to the first connector 52 of the adapter module 5 arranged inside the vehicle body 1. The adapter module 5 arranged outside the vehicle body 1 and the adapter module 5 arranged inside the vehicle body 1 are connected by the flexible circuit board body 41 and the two second connectors 42. The flexible circuit board body 41 can pass through the inherent gap of the vehicle body 1 to ensure the transmission of electrical signals of the vehicle electronic equipment under the premise of protecting the integrity of the vehicle body 1.

[0050] The inner wall surface of one of the first shell 511 and the second shell 512 presses the second connector 42 of the flexible circuit board 4 toward the first connector 52. In this embodiment, the wire connection unit 53 is provided in the second shell 512, and the first connector 52 can be installed on the adapter plate 531 of the wire connection unit 53, and the side of the adapter plate 531 on which the first connector 52 is installed faces the first shell 511. In order to make the connection between the first connector 52 and the second connector 42 stable, by setting the first shell 511 to have a suitable thickness, after the first connector 52 is connected to the second connector 42 and the first shell 511 is covered on the second shell 512, the inner wall surface of the first shell 511 can abut against the second connector 42. At this time, the first shell 511 will generate pressure on the second connector 42 in the direction of the first connector 52 to prevent the connection between the first connector 52 and the second connector 42 from being loose.

[0051] In order to further save the material of the first housing 511, an extension portion can be provided on the inner wall of the first housing 511 at a position corresponding to the second connector 42 and convexly toward the first connector 52, and the second connector 42 can be pressed by the extension portion, so that the material usage of the first housing 511 can be reduced while ensuring the stable connection between the first connector 52 and the second connector 42, thereby saving costs. An elastic sheet, such as soft rubber, can be provided at the bottom of the extension portion to adapt to the assembly tolerance to ensure that the elastic sheet can always abut the second connector 42.

[0052] Similarly, in other embodiments, if the wire connection unit 53 is disposed in the first shell 511 , the second shell 512 is provided with a suitable thickness or an extension portion is provided in the second shell 512 to press against the second connector 42 , thereby ensuring a stable connection between the first connector 52 and the second connector 42 .

[0053] It can be understood that the first connector 52 and the second connector 42 can be board-to-board connectors, and the voltage connector 532, the signal connector 534 and the CAN connector 533 can all be board-to-wire connectors. On the adapter board 531, the power supply, signal, etc. transmitted by the flexible circuit board 4 are transmitted from the second connector 42 to the first connector 52. In addition, the first connector 52 transmits the power supply and signal to the corresponding board-to-wire connector through different wirings arranged on the adapter board 531.

[0054] Since the cover force between the first shell 511 and the second shell 512 must take into account the overall performance of the adapter module 5, it is difficult to completely compress the flexible circuit board body 41. In order to solve this problem, the bumps during the driving of the vehicle are prevented from causing the fit between the first connector 52 and the second connector 42 to loosen. In some embodiments, the adapter module 5 further includes a first clamping member 55 and a second clamping member 56, which are disposed inside the shell 51 and are arranged opposite to each other. The first clamping member 55 and the second clamping member 56 are located between the first connector 52 and one end of the shell 51 for passing the flexible circuit board 4.

[0055] Specifically, the first clamping member 55 and the second clamping member 56 are used to clamp the flexible circuit board 4, for example, the flexible circuit board body 41, to strengthen the positioning of the flexible circuit board 4, and prevent the bumps during the driving of the vehicle from pulling the flexible circuit board 4 and causing the fit between the first connector 52 and the second connector 42 to loosen. It can be understood that the position where the flexible circuit board 4 penetrates the shell 51 is the end of the shell 51 for penetrating the flexible circuit board 4, and the first clamping member 55 and the second clamping member 56 can be clamped at any position of the part of the flexible circuit board 4 that penetrates the shell 51.

[0056] Specifically, the first connector 52 is disposed on the adapter plate 531, and the first clamping member 55 and the second clamping member 56 are disposed between the adapter plate 531 and the side wall of the housing 51. The first clamping member 55 and the second clamping member 56 respectively press against the two sides of the flexible circuit board 4. In one implementation, the first clamping member 55 and the first connector 52 are arranged on one of the first housing 511 and the second housing 512, and the second clamping member 56 is arranged on the other of the first housing 511 and the second housing 512. The first clamping member 55 and the second clamping member 56 cooperate to clamp the circuit board body 41, and preliminarily position and fix the flexible circuit board 4. In another implementation, the first clamping member 55 and the first connector 52 are arranged on one of the first housing 511 and the second housing 512, and the second clamping member 56 is detachably connected to the first clamping member 55, for example, detachably connected by screws. When in use, first remove the second clamping member 56 , place the flexible circuit board body 41 on the first clamping member 55 , and then install the second clamping member 56 on the first clamping member 55 . The first clamping member 55 and the second clamping member 56 cooperate to clamp the circuit board body 41 .

[0057] In some embodiments, in order to prevent the second clamping member 56 and the first clamping member 55 from damaging the flexible circuit board 4, at least one of the first clamping member 55 and the second clamping member 56 is provided with an elastic pad 57. When the first clamping member 55 or the second clamping member 56 is provided with the elastic pad 57, the first clamping member 55 or the second clamping member 56 and the elastic pad 57 respectively press against both sides of the flexible circuit board 4. For example: if the first clamping member 55 is provided with the elastic pad 57, the second clamping member 56 and the elastic pad 57 respectively press against both sides of the flexible circuit board 4.

[0058] Alternatively, when both the first clamping member 55 and the second clamping member 56 are provided with elastic pads 57 , the elastic pads 57 of the first clamping member 55 and the elastic pads 57 of the second clamping member 56 respectively press against two sides of the flexible circuit board 4 .

[0059] Therefore, by providing the first clamping member 55 , the second clamping member 56 and the elastic pad 57 , it is possible to fix the flexible circuit board 4 while ensuring that the flexible circuit board 4 is not damaged.

[0060] In some embodiments, an anti-skid pad (not shown in the figure) is also bonded to the outer surface of the shell 51. The adapter module 5 located outside the vehicle body 1 is used to abut against the outside of the vehicle body 1. For example, the anti-skid pad is provided on the bottom surface of the shell 51 of the adapter module 5 outside the vehicle body 1. The adapter module 5 is directly placed on the outer top of the vehicle body 1. By providing the anti-skid pad, both shock absorption and anti-skid can be achieved. The anti-skid soft glue is specifically made of silicone. Similarly, the adapter module 5 located inside the vehicle body 1 is used to abut against the inside of the vehicle body 1. For example, the anti-skid pad is provided on the top surface of the shell 51 of the adapter module 5 inside the vehicle body 1. It can be understood that the adapter module 5 located inside the vehicle body 1 can be bonded to the inside of the vehicle body 1 to achieve fixation.

[0061] See also Figure 6 In order to stably set the adapter module 5 located outside the vehicle body 1 outside the vehicle body 1, the adapter device also includes a buffer component 6, one end of the buffer component 6 is connected to the shell 51, and the other end of the buffer component 6 is used to connect with the external device 3, and the buffer component 6 is configured to apply an elastic force to the shell 51 in the direction of the vehicle body 1. Among them, if the buffer component 6 is installed on the top of the vehicle, the buffer component 6 applies an elastic force to the shell 51 along the direction of gravity. It can be understood that, under normal circumstances, the force generated by the bumping of the vehicle body 1 will form a trend for the adapter module 5 to approach or move away from the vehicle body 1. Since the buffer component 6 is configured to apply an elastic force to the shell 51 in the direction of the vehicle body 1, the force generated by the bumping will be transmitted to the buffer component 6 through the adapter module 5, and the buffer component 6 can absorb the transmitted force, so that the adapter module 5 is closely attached to the outside of the vehicle body 1. On the other hand, by setting up the buffer component 6, the adapter device can also be adapted to different means of transportation. That is, even if different means of transportation can provide installation environments at different heights, the adapter device can be adapted to installation environments at different heights under the elastic adjustment of the buffer component 6.

[0062] In some embodiments, Figure 6As shown, the buffer assembly 6 includes a connector 61 and an elastic connector assembly, one end of the connector 61 is connected to the elastic connector assembly, the other end of the connector 61 is used to connect to the external device 3, the elastic connector assembly is connected to the housing 51, and applies an elastic force to the housing 51 in the direction of the vehicle body 1. Specifically, the connector 61 can be a plate body, at least two through holes are provided in the length direction of the plate body, the connector 61 is connected to the external device body through a fastener at one through hole position, for example, a detachable connection; the connector 61 is connected to the elastic connector assembly at another through hole position. The elastic connector assembly is configured to apply an elastic force to the housing 51 in the direction of the vehicle body 1. When the force generated by the bump acts on the elastic connector assembly, the connector 61 will hinder the elastic connector assembly from moving in the direction away from the vehicle body 1, so the elastic connector assembly will deform to absorb the force applied to the adapter module 5 by the vehicle body 1 due to the bump, so that the adapter module 5 is closely attached to the outside of the vehicle body 1.

[0063] In some embodiments, the elastic connection assembly includes a connecting rod 62, an elastic member 63 and a first stopper 64. The connecting rod 62 is inserted into the connecting member 61 and can slide relative to the connecting member 61. The second end of the connecting rod 62 is fixedly connected to the housing 51, for example, the second end of the connecting rod 62 is fixedly connected to the first housing 511, and the two ends of the elastic member 63 are respectively abutted against the housing 51 and the connecting member 61. For example, the elastic member 63 is a spring, which is sleeved on the connecting rod 62, the first end of the elastic member 63 is abutted against the housing 51, and the second end of the elastic member 63 is abutted against the connecting member 61. The first stopper 64 is fixed to the first end of the connecting rod 62 and abuts against the connecting member 61.

[0064] On the one hand, the elastic member 63 can release the force generated by the bumping of the vehicle body 1. Specifically, after the force generated by the bumping of the vehicle body 1 is transmitted to the elastic member 63, the elastic member 63 is deformed to absorb and disperse the energy. On the other hand, the elastic member 63 can also be applicable to different vehicle bodies 1 to ensure that the adapter module 5 can be closely attached to the outer side of the vehicle body 1 for various types of vehicle bodies 1. It can be understood that in some other embodiments, the elastic member 63 can be an elastic rubber, which is sleeved on the connecting rod 62.

[0065] Specifically, the first stopper 64 is threadedly locked on the first end of the connecting rod 62. The other end of the connecting rod 62 is provided with a protrusion 621, and the protrusion 621 abuts against the inner wall of the first shell 511 to be fixedly connected with the first shell 511. Preferably, a gasket (not shown in the figure) is provided at the abutment between the protrusion 621 and the first shell 511 to prevent the protrusion 621 from damaging the inner wall of the first shell 511.

[0066] In some embodiments, the elastic connection assembly further includes a fastener 65, and the fastener 65 abuts against one end of the first stopper 64 away from the connection member 61. The fastener 65 and the first stopper 64 are both threadedly connected to the connection rod 62, and the tightening directions of the fastener 65 and the first stopper 64 are opposite. This can prevent the first stopper 64 from loosening when it is locked on the connection rod 62. Specifically, the fastener 65 and the first stopper 64 can both be nuts, and the locking directions are opposite. If the vibration of the vehicle body 1 causes one of the fastener 65 and the first stopper 64 to rotate, the first stopper 64 and the fastener 65 will be tightened, thereby preventing the position of the connection member 61 from loosening.

[0067] In some embodiments, since the outer shell 51 is relatively thin and the elastic coefficient of the elastic member 63 is relatively large, in order to prevent the elastic member 63 from squeezing the outer shell 51 and causing the outer shell 51 to deform when the vehicle body 1 bumps, the elastic connection assembly further includes a second stopper 66, and the second stopper 66 is disposed between the outer shell 51 and the elastic member 63. Preferably, the second stopper 66 is a nut and is sleeved on the connecting rod 62. A gasket is provided at the abutment between the second stopper 66 and the outer shell 51 to prevent the second stopper 66 from damaging the outer wall of the outer shell 51.

[0070] The adapter device of the present invention electrically connects the external device 3 and the internal device 2 respectively through two adapter modules 5, and the two adapter modules 5 are electrically connected through a flexible circuit board 4, so as to realize the electrical connection between the external device 3 and the internal device 2.
