[0049] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0050] In the description of the present invention, it should be clarified that the terms "vertical", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "horizontal" and the like indicating orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not mean that the device or element referred to must have a specific orientation or position, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] Example 1

[0052] like Figure 1 As shown, Embodiment 1 of the present invention provides a vehicle-mounted device, such as a vehicle-mounted frequency jammer or a vehicle-mounted detector or other vehicle-mounted device, which is configured to be installed on a vehicle body 5 to improve the flexibility of the vehicle-mounted device, and the vehicle body 5 can be driven to move the vehicle-mounted device to a target location as required. The vehicle body 5 has a gap connecting the outside and the inside of the vehicle body.

[0053] In this embodiment, the vehicle-mounted device includes an external module 2, an internal module 3, and a flexible circuit board 4. The external module 2 is installed outside the vehicle body 5. The internal module 3 is installed inside the vehicle body 5. The flexible circuit board 4 electrically connects the external module 2 and the internal module 3, and the flexible circuit board 4 passes through the gap.

[0054] The vehicle exterior module 2 can be installed on the top of the vehicle body 5 (such as Figure 1The flexible circuit board 4 transmits power or signals, for example. In the embodiment of the present invention, the external module 2 and the internal module 3 are electrically connected by the flexible circuit board 4 to transmit power or signals. Since the flexible circuit board 4 is thin and bendable, the flexible circuit board 4 can pass through the original gap of the vehicle body 5 connecting the outside and the inside of the vehicle itself, without destroying the structure of the vehicle itself, and will not affect the waterproof effect of the vehicle's waterproof structure, so there is no need to change the waterproof structure of the vehicle itself, which is convenient for the installation of vehicle-mounted equipment.

[0055] In the specific implementation process of this embodiment 1, Figure 2-Figure 13 As shown, the gap through which the flexible circuit board 4 passes can be specifically the first gap 1 formed between the body 51 of the vehicle body 5 and the tailgate 52, that is, the flexible circuit board 4 passes through the gap formed by the structure of the vehicle body 5 itself, so there is no need to specially process the vehicle body 5 to form the gap, which reduces the requirements for the vehicle. It can be understood that the first gap 1 formed between the tailgate 52 and the body 51 when it is closed is small in width and is an irregular continuous curved surface. The flexible circuit board 4 can pass through the first gap 1 formed between the tailgate 52 and the body 51 because of its thin thickness and good bending properties, and will not be affected when the tailgate 52 rotates relative to the body 51 to open or close the vehicle trunk. It should be noted that in other embodiments, the flexible circuit board 4 can also pass through the gap formed between the door of the vehicle body 5 (the door is not shown in the figure) and the body 51 or the gap formed between the window of the vehicle body 5 and the door (the window and the door are not shown in the figure).

[0056] In the specific implementation process of this embodiment 1, Figure 2-Figure 9 As shown, a guide groove 11 is provided on one side of the first gap 1, and the flexible circuit board 4 passes through the top of the guide groove 11. For example, the body 51 is provided with a guide groove 11 at a position corresponding to the first gap 1. Specifically, as Figure 1 and Figure 3As shown, the first gap 1 includes a flat section 13 and a gap side section 14 connecting the two ends of the flat section 13. In the direction of gravity, the flat section 13 is located above the gap side section 14, and the guide groove 11 is extended along the flat section 13. In this embodiment, the positional relationship between the flexible circuit board 4 and the guide groove 11 can be determined based on the direction of gravity, that is, the height of the portion of the flexible circuit board 4 passing through the guide groove 11 is higher than the height of the bottom wall of the guide groove 11. The function of the guide groove 11 is to collect water droplets flowing along the flexible circuit board 4 or flowing into the flat section 13 of the first gap 1 along the vehicle body 51 into the guide groove 11, and flow along the guide groove 11 to the gap side section 14 of the first gap 1 for discharge. In addition, since the flexible circuit board 4 passes through the top of the guide groove 11, the water droplets will directly drip into the guide groove 11 due to the action of gravity, and will not enter the interior of the vehicle along the flexible circuit board 4.

[0057] It is understandable that in order to prevent rainwater from entering the vehicle body 5 through the first gap 1, the vehicle is further provided with a sealing structure on one side of the first gap 1, that is, the vehicle body 51 is provided with a first elastic member 12 at the position of the first gap 1, and the first elastic member 12 is originally used to press the tailgate 52 to prevent rainwater from passing through. Figure 2-Figure 5 As shown, the flexible circuit board 4 passes through the position of the first elastic member 12 corresponding to the first gap 1. The first elastic member 12 and the tailgate 52 respectively press against the two sides of the flexible circuit board 4 to prevent rainwater from passing through the gap between the flexible circuit board 4 and the first elastic member 12 and the tailgate 52, and the flexible circuit board 4 will not damage the first elastic member 12, so it will not affect the waterproof sealing of the vehicle itself. In addition, the first elastic member 12 is made of waterproof or dense elastic material, so the first elastic member 12 and the flexible circuit board 4 squeeze each other so that the liquid cannot pass between the contact surfaces of the two, and because the first elastic member 12 is elastic, it is easier to adapt to the shape or thickness of the flexible circuit board 4 than other parts made of rigid materials (in other words, it has higher compatibility with the flexible circuit board 4 and is easier to implement). It should be noted that the first elastic member 12 is a sealing rubber ring, silicone, rubber or other parts that achieve a sealing effect, which are all within the protection scope of this embodiment.

[0058] In other embodiments, Figure 6-Figure 9 As shown, the vehicle is provided with first elastic members 12 on both sides of the first gap 1, for example: first elastic members 12 are provided on both sides of the first gap 1 between the tailgate 52 and the vehicle body 51, that is, one of the first elastic members 12 is provided on the vehicle body 51, and the other first elastic member 12 is provided on the tailgate 52. When the tailgate 52 is closed, the two first elastic members 12 are respectively pressed against both sides of the same section of the flexible circuit board 4 to prevent rainwater from passing through.

[0059] It is understandable that the shape of the first elastic member 12 can be set according to requirements, for example Figure 6-Figure 9 The shape of the first elastic member 12 is Figure 10-13 The shape of the first elastic member 12 is different. The setting position of the first elastic member 12 can also be changed according to needs, such as Figure 6-Figure 9 As shown, the first elastic member 12 is disposed at a position of the first gap 1 close to the interior space of the vehicle, and one end of the first elastic member 12 disposed on the vehicle body 51 is connected to the guide groove 11, so that the water drops intercepted by the first elastic member 12 flow into the guide groove 11. Figure 10-13 As shown, the first elastic member 12 is disposed at a position of the first gap 1 close to a hinge point between the vehicle body 51 and the tailgate 52 .

[0060] In the specific implementation process of this embodiment 1, the thickness of the flexible circuit board 4 is not more than 1 mm. In this way, it is easier for the flexible circuit board 4 to pass through the first slit 1 to avoid being subjected to excessive squeezing force when passing through the first slit 1, which affects the performance and service life of the flexible circuit board 4.

[0061] It should be noted that the off-board module 2 can be a high-power device, so the flexible circuit board 4 needs to transmit high voltage (220V and above). In order to meet the above requirements, in the specific implementation process of this embodiment 1, Fig.14 and Fig.15 As shown, the flexible circuit board 4 may specifically include a substrate layer 41, a transmission line layer 42 and a multi-layer coating layer 43. The transmission line layer 42 is disposed on the substrate layer 41. The multi-layer coating layer 43 is disposed on a side of the transmission line layer 42 away from the substrate layer 41. The substrate layer 41, the transmission line layer 42 and the coating layer 43 are all bendable.

[0062] In this embodiment, a multi-layer coating layer 43 is provided to prevent high voltage electricity from breaking through the coating layer 43, so that the insulation of the flexible circuit board 4 meets the requirements of high voltage transmission. In addition, the provision of the multi-layer coating layer 43 can also improve the wear resistance of the flexible circuit board 4 and the sealing and waterproof performance of the transmission line layer 42. The material of the coating layer 43 is, for example, polyimide.

[0063] It should be noted that if the thickness of the substrate layer 41 meets the insulation requirements and will not be broken down by high voltage electricity, the coating layer 43 may not be provided on the side of the substrate layer 41 away from the transmission line layer 42. Alternatively, the coating layer 43 may also be provided on the side of the substrate layer 41 away from the transmission line layer 42 as required to further improve the high voltage resistance performance. Of course, the number of coating layers 43 on the side of the substrate layer 41 away from the transmission line layer 42 may be lower than the number of coating layers 43 on the side of the substrate layer 41 facing the transmission line layer 42.

[0064] In the specific implementation process of this embodiment 1, Fig.15As shown, the transmission line layer 42 has a plurality of transmission lines 421 , and the plurality of transmission lines 421 are at the same level in the normal direction of the substrate layer 41 , so as to reduce the thickness of the flexible circuit board 4 .

[0065] The plurality of transmission lines 421 include copper wires for transmitting signals and copper wires for transmitting power. The copper wires for transmitting signals and the copper wires for transmitting power are arranged at intervals to avoid mutual interference.

[0066] In the specific implementation process of this embodiment 1, Figure 1 As shown, the vehicle-outside module 2 includes an outside functional unit 21 and a wiring unit 22 located outside the vehicle. The vehicle-inside module 3 includes an inside functional unit 31 and a wiring unit 22 located inside the vehicle. The two ends of the flexible circuit board 4 are electrically connected to the wiring unit 22 located outside the vehicle and the wiring unit 22 located inside the vehicle, respectively. The wiring unit 22 located outside the vehicle is also electrically connected to the outside functional unit 21, and the wiring unit 22 located inside the vehicle is also electrically connected to the inside functional unit 31, so as to realize power or signal transmission inside and outside the vehicle.

[0067] It should be noted that the off-vehicle functional unit 21 is, for example, a unit for executing a device function, and the on-vehicle functional unit 31 includes, for example, a unit for controlling the off-vehicle functional unit 21 to execute a device function and a power supply unit. This embodiment is explained by taking the vehicle-mounted device as a vehicle-mounted frequency jammer. The off-vehicle functional unit 21 includes an interference module, an antenna, and other units for executing interference functions. The on-vehicle functional unit 31 includes a host, a power supply, and the like, wherein the host can control the interference module, and the power supply is used to supply power. The wiring unit 22 located outside the vehicle, the flexible circuit board 4, and the wiring unit 22 located inside the vehicle can transmit power and signals between the off-vehicle functional unit 21 and the on-vehicle functional unit 31.

[0068] In the specific implementation process of this embodiment 1, Fig.16 As shown, the wiring unit 22 includes a housing 221 and a communication component 222 disposed in the housing 221. The housing 221 is provided with an elastic structure 223. The flexible circuit board 4 passes through the elastic structure 223 and is connected to the communication component 222. The elastic structure 223 is used to ensure the waterproof sealing of the position where the flexible circuit board 4 passes through, and because the elastic structure 223 is elastic, it can also avoid crushing the flexible circuit board 4.

[0069] like Fig.14 and Fig.16As shown, the communication component 222 may specifically include a signal adapter board 2221 and a first connector 2222 provided on the signal adapter board 2221, a second connector 44 is provided at one end of the flexible circuit board 4, and the first connector 2222 and the second connector 44 are electrically connected by buckling. The signal adapter board 2221 may also be provided with a signal connector 2223, a CAN connector 2224, and a voltage connector 2225. The signal adapter board 2221 may also be provided with a high-voltage power supply line (not shown in the figure), and the high-voltage power supply line connects the voltage connector 2225 and the first connector 2222. The signal adapter board 2221 may also be provided with a signal line (not shown in the figure), and the signal line connects the signal connector 2223 and the first connector 2222. The signal adapter board 2221 may also be provided with a bus line, and the bus line connects the CAN connector 2224 and the first connector 2222 thereon. The high-voltage power supply line includes a live line and a neutral line, and there is a certain distance between the live line and the neutral line to prevent high voltage breakdown. The signal connector 2223 , the CAN connector 2224 , and the voltage connector 2225 can all be board-to-wire connectors, which are used to convert the high-voltage power supply and signals transmitted by the flexible circuit board 4 into conventional cable signals for transmission.

[0070] In the specific implementation process of this embodiment 1, Fig.16 As shown, the housing 221 includes a bottom housing 2211 and a cover 2212 connected to the bottom housing 2211, and the elastic structure 223 includes a second elastic member 2231 and a third elastic member 2232. The second elastic member 2231 is arranged on the side of the bottom housing 2211 facing the cover 2212, and the third elastic member 2232 is arranged on the side of the cover 2212 facing the bottom housing 2211. The flexible circuit board 4 is inserted between the second elastic member 2231 and the third elastic member 2232. The second elastic member 2231 and the third elastic member 2232 respectively press the opposite sides of the flexible circuit board 4 to achieve a close fit between the second elastic member 2231, the third elastic member 2232 and the flexible circuit board 4, and prevent the gap around the flexible circuit board 4 from being flowed into the housing 221 by rainwater, so as to achieve a sealing and waterproof effect. In addition, since the second elastic member 2231 and the third elastic member 2232 are elastic, the flexible circuit board 4 can also be prevented from being crushed.

[0071] More specifically, the third elastic member 2232 is bonded to the periphery of the cover 2212, and the second elastic member 2231 is bonded to the periphery of the bottom shell 2211. When the cover 2212 is buckled onto the bottom shell 2211, the second elastic member 2231 abuts against the third elastic member 2232 to ensure the waterproof sealing of the bottom shell 2211 and the cover 2212. The second elastic member 2231 and the third elastic member 2232 can be sealing rings, silicone, rubber or other components that can play a sealing and protective role.

[0072] In the specific implementation process of this embodiment 1, Fig.16 As shown, the wiring unit 22 also includes a crimping piece 224, which is arranged on the bottom shell 2211 and is located between the communication component 222 and one end of the bottom shell 2211 through which the flexible circuit board 4 is passed. The flexible circuit board 4 is pressed by the crimping piece 224 to prevent the fit between the first connector 2222 and the second connector 44 from loosening, thereby ensuring the connection reliability of the flexible circuit board 4.

[0073] It should be noted that the crimping piece 224 can be fixed on the bottom shell 2211 by a fixing piece. When the flexible circuit board 4 is connected to the wiring unit 22, the second connector 44 of the flexible circuit board 4 is first connected to the first connector 2222 of the signal adapter board 2221, and then the flexible circuit board 4 is pressed against the bottom shell 2211 by the crimping piece 224, and then the crimping piece 224 is fixed by a fixing piece, and finally the cover body 2212 is snapped on the bottom shell 2211 to complete the connection between the flexible circuit board 4 and the wiring unit 22. Among them, the crimping piece 224 is, for example, arranged in a long strip shape. The material of the crimping piece 224 is silicone, rubber or other elastic materials. The fixing piece can be a screw, a screw, a bolt or other parts that play a fastening role.

[0074] In order to prevent the first elastic member 12 from aging and losing its original elasticity after long-term use and failing to achieve the initial waterproof sealing effect, causing rainwater to flow along the flexible circuit board 4 to the wiring unit 22 located in the vehicle, there is a risk of rainwater infiltrating the wiring unit 22 located in the vehicle. In the specific implementation process of this embodiment 1, as Figure 17-Figure 19 As shown, the vehicle-mounted device also includes a shut-off member 6, which is installed on the flexible circuit board 4 and located inside the vehicle body 5. The shut-off member 6 has a guide surface 61, one end of the guide surface 61 is connected to the surface of the first position 45 of the flexible circuit board 4, and the other end of the guide surface 61 has a set distance relative to the surface of the second position 46 of the flexible circuit board 4. The height of the first position 45 along the gravity direction is higher than the height of the second position 46 along the gravity direction, that is, the guide surface 61 has an inclination angle relative to the surface of the flexible circuit board 4, so that when rainwater flows to the first position 45 of the flexible circuit board 4, it will flow to the guide surface 61 instead of continuing to flow downward along the flexible circuit board 4, thereby preventing water droplets from entering the wiring unit 22 located in the vehicle, further improving the waterproof performance of the vehicle-mounted device.

[0075] In this embodiment, if Figure 17-Figure 19As shown, the intercepting member 6 is also provided with a wire hole 62, and the flexible circuit board 4 is provided with the wire hole 62. The intercepting member 6 is divided into a first part 6a and a second part 6b along the extension direction of the wire hole 62. The second part 6b is located on the side of the first part 6a facing the in-vehicle module 3. The first part 6a is provided with a guide surface 61, and the second part 6b is provided with a fastening structure 63. The fastening structure 63 is configured to make the hole wall of the wire hole 62 of the second part 6b fit with the flexible circuit board 4 to prevent water droplets from passing through the gap between the flexible circuit board 4 and the wire hole 62, thereby improving the waterproof performance of the intercepting member 6. Among them, the first part 6a and the second part 6b can be integrally formed or detachably arranged. The wire hole 62 runs through the middle part of the first part 6a and the second part 6b.

[0076] In this embodiment, if Fig.19 As shown, the first part 6a has two guide surfaces 61, and the flexible circuit board 4 has two surfaces arranged opposite to each other. The two guide surfaces 61 are connected to the two surfaces of the flexible circuit board 4, that is, both the front and back sides of the intercepting member 6 have guide surfaces 61. Therefore, no matter which side of the flexible circuit board 4 the water droplets flow in from, they can flow along the guide surfaces 61. And when installing the intercepting member 6 to the flexible circuit board 4, it is not necessary to consider the installation direction of the intercepting member 6, which simplifies the installation of the intercepting member 6. Among them, the two guide surfaces 61 are inclined downward and outward relative to the flexible circuit board 4.
