[0049] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to specific embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0050] In the description of this application, it should be clarified that the terms "vertical", "transverse", "longitudinal", "front", "rear", "left", "right", "up", "down", "horizontal", etc. indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and do not mean that the devices or elements referred to must have a specific orientation or position. Therefore, they cannot be understood as limitations on this application. In the description of this application, 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 ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] Example 1

[0052] like Figure 1 and Figure 14 As shown, Example 1 of the present application provides a vehicle-mounted device, such as a vehicle-mounted frequency jammer or a vehicle-mounted detector, or other vehicle-mounted device. The vehicle-mounted device is configured to be mounted on a vehicle body 5 to improve the flexibility of the vehicle-mounted device. The vehicle body 5 can be driven to move the vehicle-mounted device to a target location as needed. The vehicle body 5 has a gap connecting its exterior and interior.

[0053] In this embodiment, the vehicle-mounted device includes an off-vehicle module 2, an on-vehicle module 3, and a flexible circuit board 4. The off-vehicle module 2 is mounted outside the vehicle body 5. The on-vehicle module 3 is mounted inside the vehicle body 5. The flexible circuit board 4 is provided with an electrical connector 44, which electrically connects the off-vehicle module 2 and the on-vehicle module 3. 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 (e.g. Figure 1 The flexible circuit board 4 transmits power or signals, for example. In the embodiment of the present application, 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 that connects the outside and the inside of the vehicle itself, without destroying the structure of the vehicle itself and without affecting the waterproof effect of the vehicle's waterproof structure. Therefore, there is no need to modify the waterproof structure of the vehicle itself, which facilitates the installation of vehicle-mounted equipment.

[0055] In the specific implementation process of this embodiment 1, as Figure 2-13 As shown, the gap through which the flexible circuit board 4 passes can specifically be the first gap 1 formed between the vehicle body 51 and the tailgate 52 of the vehicle body 5. That is, the flexible circuit board 4 passes through the gap formed by the structure of the vehicle body 5 itself. Therefore, no special processing is required on the vehicle body 5 to form the gap, reducing the requirements for the vehicle. It can be understood that the first gap 1 formed between the tailgate 52 and the body 51 when closed is small and has an irregular continuous curve. Due to its thinness and good flexibility, the flexible circuit board 4 can pass through the first gap 1 formed between the tailgate 52 and the body 51 and is not 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 (door not shown in the figure) and the body 51, or the gap formed between the window of the vehicle body 5 and the door (window and door not shown in the figure).

[0056] In the specific implementation process of this embodiment 1, as 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, Figure 1 and Figure 3As shown, the first slit 1 includes a flat section 13 and a slit 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 slit side section 14, and the guide groove 11 extends along the flat section 13. In this embodiment, the positional relationship between the flexible circuit board 4 and the guide groove 11 is determined based on the direction of gravity. That is, the portion of the flexible circuit board 4 passing through the guide groove 11 is located at a higher height than 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 along the vehicle body 51 into the flat section 13 of the first slit 1 into the guide groove 11, and then flow along the guide groove 11 to the slit side section 14 of the first slit 1 for discharge. Furthermore, because the flexible circuit board 4 passes through the guide groove 11 from above, water droplets will drip directly into the guide groove 11 due to gravity, rather than entering the vehicle interior along the flexible circuit board 4.

[0057] It is understood 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. The first elastic member 12 is originally used to press the tailgate 52 to prevent rainwater from passing through. In the specific implementation process of this embodiment 1, as shown in FIG. 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. In addition, the flexible circuit board 4 will not damage the first elastic member 12, and thus will not affect the waterproof sealing of the vehicle itself. In addition, the first elastic member 12 is made of a waterproof or dense elastic material. Therefore, the first elastic member 12 and the flexible circuit board 4 squeeze each other, so that liquid cannot pass through the contact surface between the two. Moreover, due to the elasticity of the first elastic member 12, it is easier to adapt to the shape or thickness of the flexible circuit board 4 than other components 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 components that achieve a sealing function, all of which are within the scope of protection 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 the two 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 needs, for example Figure 6-Figure 9 The shape of the first elastic member 12 is similar to 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 arranged at a position close to the interior space of the vehicle in the first gap 1, and one end of the first elastic member 12 arranged on the vehicle body 51 is connected to the guide groove 11, so that the water droplets intercepted by the first elastic member 12 can flow into the guide groove 11. Or as Figure 10-13 As shown, the first elastic member 12 is provided at a position of the first gap 1 close to the 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 greater than 1 mm. This makes it easier for the flexible circuit board 4 to pass through the first slit 1, thereby avoiding 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, Figure 14 and Figure 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 the side of the transmission line layer 42 facing away from the substrate layer 41. The substrate layer 41, the transmission line layer 42, and the coating layer 43 are all bendable.

[0062] This embodiment employs a multi-layer coating layer 43 to prevent high-voltage electrical breakdown, thereby ensuring that the insulation properties of the flexible circuit board 4 meet the requirements for high-voltage transmission. Furthermore, the multi-layer coating layer 43 enhances the wear resistance of the flexible circuit board 4 and provides a waterproof seal to the transmission line layer 42. The coating layer 43 is made of, for example, polyimide.

[0063] It should be noted that if the thickness of the substrate layer 41 meets insulation requirements and is not susceptible to breakdown by high voltage electricity, the coating layer 43 may not be provided on the side of the substrate layer 41 facing away from the transmission line layer 42. Alternatively, the coating layer 43 may be provided on the side of the substrate layer 41 facing away from the transmission line layer 42 as needed to further enhance high-voltage resistance. Of course, the number of coating layers 43 on the side of the substrate layer 41 facing 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, as Figure 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 spaced apart to avoid mutual interference.

[0066] In the specific implementation process of this embodiment 1, as Figure 1 As shown, the off-board module 2 includes an off-board functional unit 21 and a wiring unit 22 located outside the vehicle. The on-board module 3 includes an on-board functional unit 31 and a wiring unit 22 located inside the vehicle. The two ends of the flexible printed 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, via the electrical connector 44. The wiring unit 22 located outside the vehicle is also electrically connected to the off-board functional unit 21, and the wiring unit 22 located inside the vehicle is also electrically connected to the on-board functional unit 31, thereby enabling power or signal transmission between the vehicle and the outside.

[0067] It should be noted that the off-vehicle functional unit 21 is, for example, a unit that performs device functions, and the on-vehicle functional unit 31 includes, for example, a unit that controls the off-vehicle functional unit 21 in performing its functions and a power supply unit. This embodiment is explained using the vehicle-mounted device as a vehicle-mounted frequency jammer. The off-vehicle functional unit 21 includes a jamming module, an antenna, and other units for performing jamming functions. The on-vehicle functional unit 31 includes a host computer and a power supply, among others. The host computer controls the jamming module, and the power supply provides power. The wiring unit 22 located outside the vehicle, the flexible printed 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, as Figure 16 As shown, the wiring unit 22 includes a housing 221 and a communication assembly 222 disposed within the housing 221. The housing 221 is provided with an elastic structure 223. The flexible printed circuit board 4 passes through the elastic structure 223 and is connected to the communication assembly 222 via the electrical connector 44. The elastic structure 223 ensures a waterproof seal at the location where the flexible printed circuit board 4 passes through. Due to its elasticity, the elastic structure 223 also prevents damage to the flexible printed circuit board 4.

[0069] like Figure 14 and Figure 16As shown, the communication component 222 may specifically include a signal adapter board 2221 and a first connector 2222 disposed on the signal adapter board 2221. An electrical connector 44 is provided at the end of the flexible circuit board 4. The first connector 2222 and the electrical connector 44 engage and electrically connect. An electrical connector 44 may be provided at each end of the flexible circuit board 4. The portion between the two electrical connectors 44 forms the main body of the flexible circuit board 4. In this embodiment, the main body of the flexible circuit board 4 passes through the aforementioned gap (such as the first gap 1), the elastic structure 223, and the like.

[0070] 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), which 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), which connects the signal connector 2223 and the first connector 2222. The signal adapter board 2221 may also be provided with a bus line, which connects the CAN connector 2224 and the first connector 2222 thereon. The high-voltage power supply line includes a live wire and a neutral wire, and there is a certain distance between the live wire and the neutral wire to prevent high-voltage breakdown. The signal connector 2223, the CAN connector 2224, and the voltage connector 2225 may all be board-to-line connectors for converting the high-voltage power supply and signals transmitted by the flexible circuit board 4 into conventional cable signals for transmission.

[0071] In the specific implementation process of this embodiment 1, as Figure 16 As shown, the housing 221 includes a bottom housing 2211 and a cover 2212 connected to the bottom housing 2211. The elastic structure 223 includes a second elastic member 2231 and a third elastic member 2232. The second elastic member 2231 is disposed on the side of the bottom housing 2211 facing the cover 2212, and the third elastic member 2232 is disposed on the side of the cover 2212 facing the bottom housing 2211. The flexible circuit board 4 is disposed 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 against opposite sides of the flexible circuit board 4 to ensure a tight fit between the second elastic member 2231 and the third elastic member 2232 and the flexible circuit board 4, preventing rainwater from flowing into the housing 221 through gaps around the flexible circuit board 4, thereby achieving a sealed and waterproof effect. Furthermore, due to the elasticity of the second elastic member 2231 and the third elastic member 2232, damage to the flexible circuit board 4 can also be avoided.

[0072] 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 case 2211. When the cover 2212 is fastened to the bottom case 2211, the second elastic member 2231 abuts against the third elastic member 2232 to ensure a waterproof seal between the bottom case 2211 and the cover 2212. The second elastic member 2231 and the third elastic member 2232 may be sealing rings, silicone, rubber, or other components capable of providing a sealing and protective function.

[0073] In the specific implementation process of this embodiment 1, as Figure 16 As shown, the wiring unit 22 also includes a crimping piece 224, which is provided 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 electrical connector 44 from loosening, thereby ensuring the connection reliability of the flexible circuit board 4.

[0074] It should be noted that the crimping piece 224 can be fixed to the bottom shell 2211 by a fixing piece. When the flexible circuit board 4 is connected to the wiring unit 22, the electrical connector 44 of the flexible circuit board 4 is first docked with the first connector 2222 of the signal adapter board 2221, and then the flexible circuit board 4 is pressed against the bottom shell 2211 with the crimping piece 224. The crimping piece 224 is then fixed with a fixing piece, and finally the cover 2212 is snapped onto the bottom shell 2211 to complete the connection between the flexible circuit board 4 and the wiring unit 22. The crimping piece 224 is, for example, arranged in a long strip shape. The crimping piece 224 is made of silicone, rubber, or other elastic materials. The fixing piece can be a screw, a bolt, a bolt, or other fastening component.

[0075] In order to prevent the first elastic member 12 from losing its original elasticity due to aging 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 inside the vehicle, there is a risk of rainwater seeping into the wiring unit 22 located inside the vehicle. In the specific implementation process of this embodiment 1, as shown in FIG. Figure 17-Figure 19As shown, the vehicle-mounted device also includes a shut-off member 6, which is mounted 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 inclined 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 inside the vehicle, further improving the waterproof performance of the vehicle-mounted device.

[0076] In this embodiment, if Figure 17-Figure 19 As shown, the shutoff member 6 also has a wire hole 62, through which the flexible circuit board 4 passes. The shutoff member 6 is divided into a first portion 6a and a second portion 6b along the extension direction of the wire hole 62. The second portion 6b is located on the side of the first portion 6a facing the in-vehicle module 3. The first portion 6a has a flow guide surface 61, and the second portion 6b has a fastening structure 63. The fastening structure 63 is configured to mate the wall of the wire hole 62 in the second portion 6b with the flexible circuit board 4, preventing 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 shutoff member 6. The first portion 6a and the second portion 6b can be integrally formed or detachable. The wire hole 62 runs through the middle of the first portion 6a and the second portion 6b.

[0077] In this embodiment, if Figure 19 As shown, the first portion 6a has two guide surfaces 61. The flexible circuit board 4 has two opposing surfaces, and the two guide surfaces 61 are connected to the two surfaces of the flexible circuit board 4, respectively. That is, both the front and back sides of the closure member 6 have guide surfaces 61.
