[0038] The following is combined with Figure 1-9 , further elaborate on this application.

[0039] like Figure 1 and Figure 2 As shown, Figure 1 An embodiment of the present application provides a vehicle-mounted antenna, comprising an antenna rod, a PCB circuit board, a cable assembly, and a housing structure;

[0040] Antenna masts are used to receive signals;

[0041] The PCB circuit board is used to process the signal received by the antenna rod, and the PCB circuit board is connected to the antenna rod;

[0042] The cable assembly is used to output the signal processed by the PCB and to supply power to the PCB. The cable assembly is connected to the PCB.

[0043] The shell mechanism is used to fix the position of the vehicle-mounted antenna. The shell mechanism includes a shell module and a fixing module. The fixing module is used to fix the cable assembly. The fixing module has different installation directions. The fixing module is used to cooperate with the change of the installation direction of the cable assembly. The antenna pole is connected to the shell module, and the shell module is connected to the fixing module. The cable assembly passes through the connection hole set on the shell module and is connected to the PCB circuit board. The PCB circuit board is set in the shell module.

[0044] In this embodiment, the vehicle-mounted antenna can be mounted on the vehicle or on another mobile platform. The mounting location of the vehicle-mounted antenna can be determined based on actual needs and vehicle design to ensure optimal signal reception. For example, the antenna pole can be mounted on the roof of the vehicle or above the front windshield, secured with adhesive or a dedicated clamp to reduce interference from the surrounding environment.

[0045] Antenna masts are used to receive wireless signals, including FM, AM, DAB, analog TV, digital TV (such as terrestrial digital television broadcasting (DTMB), and Direct Broadcast Satellite Service (DBS). The mast's signal reception capacity and range can be determined based on actual needs and vehicle design. Furthermore, the mast can be retractable to accommodate the installation requirements of different vehicle models.

[0046] like Figure 2 As shown, the PCB is connected to the antenna mast and is used to process the signals received by the mast. The PCB can be connected to the mast via a specific interface corresponding to the mast. The signals received by the mast are processed by a highly integrated chip. Specifically, after the antenna mast receives the wireless signal, it is transmitted to the PCB. The PCB then filters, amplifies, tunes, mixes, demodulates, and performs error correction on the signal, outputting the signal to the vehicle's multimedia system and electronic devices, such as the audio system or display device. The PCB can utilize a highly integrated chip design, reducing the size of the vehicle antenna and enabling it to meet diverse installation requirements.

[0047] The cable assembly is connected to the PCB circuit board and is used to output the signal processed by the PCB circuit board and to supply power to the PCB circuit board. Therefore, the cable assembly may include a signal cable for transmitting signals and a power supply cable for supplying power, wherein one end of the signal cable is connected to the interface for outputting signals from the PCB circuit board, and the other end can be connected to the vehicle's multimedia system and electronic equipment such as an audio system or a display device; one end of the power supply cable is connected to the power transmission port on the PCB circuit board, and the other end can be connected to the port on the vehicle for supplying power to the vehicle antenna. The signal cable and the power supply cable in the cable assembly can be fixed by a dedicated cable clamp so that the signal cable and the power supply cable are combined to form a cable assembly, or the signal cable and the power supply cable can be connected to the PCB circuit board separately, and then the signal cable and the power supply cable form a cable assembly. The length and layout of the cable assembly can be determined according to the distance between the PCB circuit board and the antenna pole, as well as the vehicle design requirements, to ensure the stability and efficiency of signal transmission and that the vehicle antenna can meet installation requirements.

[0048] The materials of the antenna pole and cable assembly can be selected from high-temperature resistant, low-temperature resistant, and corrosion-resistant materials to ensure normal operation under extreme climate conditions. In addition, the cable assembly can adopt a retractable design, so that the cable can be changed to different lengths to match the interior space of the vehicle and achieve the best installation effect.

[0049] like Figure 1As shown, the housing mechanism is used to secure the position of the vehicle-mounted antenna to facilitate installation on the vehicle, and also serves as a cover for the PCB circuit board, protecting the electronic components on the PCB. The housing mechanism includes a housing module, which serves as a mounting base for the vehicle-mounted antenna and a cover for the PCB circuit board. The PCB circuit board is mounted within the housing module. The PCB circuit board can be fixed to the housing module using connectors such as nuts, screws, and clamps, or can be fixed to the housing module using methods such as mortise and tenon joints, snap-fit ​​fixation, bonding, or threaded post fixation. The housing module can be provided with an antenna mast interface for connecting the antenna mast to the housing module. For example, threads can be provided on the housing module, and the antenna mast can be connected to the housing module and fixed using a screw on the antenna mast. In addition, the antenna rod also needs to be connected to the PCB circuit to transmit the received signal to the PCB circuit board. Therefore, one end of the antenna rod can be connected to the housing module through a through hole, that is, one end of the antenna rod passes through the housing module and is fixedly connected to the housing module and then connected to the PCB circuit board. For example, a threaded through hole is provided on the housing module, and a screw provided at one end of the antenna rod is fixedly connected to the threaded through hole on the housing module. The screw provided at one end of the antenna rod passes through the housing module, and the screw provided at one end of the antenna rod passes through the housing module and then is connected to the PCB circuit board. After the antenna rod is connected to the PCB circuit board, the received signal needs to be transmitted to the PCB circuit board. Therefore, the connection method between the antenna rod and the PCB circuit board can be by providing a spring contactor between the screw and the PCB circuit board, and the spring contactor contacts a specific solder point on the PCB circuit board when the screw is tightened to achieve signal transmission; it can also be through a crimp-type connector provided at one end of the antenna rod, which is fixed to a corresponding connector on the PCB circuit board by crimping to achieve signal transmission; it can also be through a pin connector (such as PGA or male-female pins), SMA or other types of RF connectors on the PCB circuit board, to achieve signal transmission through mechanical and electrical contact, etc. The material of the housing module can be plastic, metal or other suitable engineering materials to ensure sufficient mechanical strength and electromagnetic shielding performance.

[0050] The shell mechanism also includes a fixing module, the housing module is connected to the fixing module, and the fixing module is used to fix the cable assembly after the cable assembly is connected to the PCB circuit board to improve the connection reliability between the PCB circuit board and the cable assembly. The fixing module can be installed inside the housing module, or outside the housing module, or a part of it can be installed inside the housing module and the other part can be installed outside the housing module. For example, when the fixing module is installed inside the housing module, the fixing module can be a fixing part that is clamped with the cable assembly to fix the cable assembly. When the fixing module is installed outside the housing module, the fixing module can be a fixing part that fixes the cable assembly through a nut thread. When a part of the fixing module is installed inside the housing module and the other part is installed outside the housing module, the fixing module can include a fixing part that is clamped with the cable assembly to fix the cable assembly and a fixing part that fixes the cable assembly through a nut thread.

[0051] It is understandable that since the cable assembly needs to be connected to the PCB circuit board, and the PCB circuit board is installed inside the shell module, a connection hole is provided on the shell module, and the cable assembly can be connected to the PCB circuit board inside the shell module after passing through the connection hole provided on the shell module. In addition, since the vehicle-mounted antenna is installed on the vehicle, in order to meet the design and aesthetic requirements of the vehicle, the antenna rod can be installed on the top of the shell module, and the cable assembly will be installed in the interlayer of the vehicle shell. Therefore, the connection hole provided on the shell module can be at the bottom of the shell module, or other locations where the cable assembly can be hidden after the cable assembly is installed. The fixing module is used to fix the cable assembly. Therefore, after the cable assembly passes through the connection hole provided on the shell module and connects to the PCB circuit board, the cable assembly can be fixed by the fixing module. The fixing module is installed in conjunction with the connection hole provided on the shell module. The fixing module can also be installed at the bottom of the shell module, or other locations where the cable assembly can be hidden after the cable assembly is installed.

[0052] Furthermore, due to differences in vehicle design, the installation locations of multimedia systems and electronic devices, such as audio systems or display devices, may also vary. When the installation locations of multimedia systems and electronic devices, such as audio systems or display devices, are different but the same vehicle antenna is used, if the installation direction of the vehicle antenna cable assembly is opposite to or significantly deviates from the direction of the vehicle electronic device, the vehicle antenna may not be installed. Therefore, to improve the adaptability of the vehicle antenna, the fixing module is configured to have different installation directions. Based on this, when installing the vehicle antenna, the installation direction of the cable assembly can be selected based on the different installation directions of the fixing module to meet different assembly requirements. For example, when installing the vehicle antenna, if the cable assembly cannot be installed, for example, because the cable is too short to connect to the vehicle electronic device, the installation direction of the cable assembly needs to be changed to shorten the wiring length between the vehicle antenna and the vehicle electronic device. Therefore, the installation direction of the cable assembly can be changed. After the installation direction of the cable assembly is changed, the installation direction of the fixing module is changed to ensure smooth installation of the vehicle antenna.

[0053] In the vehicle-mounted antenna provided in some embodiments of the present application, Figure 2 As shown, the fixing module includes a threaded fixing component, a wire inlet is provided at one end of the threaded fixing component and a wire inlet notch is provided on one side of the fixing module. When the installation direction of the threaded fixing component is different, the direction of the wire inlet notch is different, and the cable assembly is connected to the PCB circuit board through the wire inlet notch and the wire inlet.

[0054] Specifically, a wire entry port is provided at one end of the threaded fixing assembly and a wire entry notch is provided at one side of the threaded fixing assembly. It is understandable that the cable assembly can be connected to the PCB circuit board after passing through the wire entry port and the wire entry notch. The threaded fixing assembly can be installed outside the shell module, and the wire entry port is provided at the top end of the threaded fixing assembly, that is, at one end close to the shell module, and a wire entry notch is provided on one side of the threaded fixing assembly. The cable assembly can pass through the wire entry notch and then through the wire entry port at the top end, and then be connected to the PCB circuit board. The threaded fixing assembly fixes the cable assembly through a fixing piece that cooperates with a thread and a nut. When the vehicle-mounted antenna is installed, after the cable assembly passes through the wire entry notch and then through the wire entry port at the top end and then is connected to the PCB circuit board, that is, after the installation direction of the cable assembly is determined, the cable assembly is not provided with a threaded fixing assembly. The nut on one end of the wire inlet cooperates with the thread to fix the installation direction of the cable assembly; if the cable assembly passes through the wire inlet notch and then through the wire inlet at the top and then connects to the PCB circuit board, and the installation direction of the cable assembly has been fixed by the nut on the end of the threaded fixing assembly where the wire inlet is not provided cooperates with the thread, if it is found that the cable assembly cannot be connected to the electronic equipment on the vehicle and the installation direction of the cable assembly needs to be changed, the nut can be removed, and the installation direction of the threaded fixing assembly can be changed according to the required changed installation direction of the cable assembly to change the direction of the wire inlet notch, and then the installation direction of the cable assembly can be changed, and then the installation direction of the cable assembly can be fixed by the nut and thread.

[0055] It can be understood that the cable assembly is connected to the PCB circuit board after passing through the connection hole set on the shell module, and the fixing module is connected to the shell module. Therefore, the cable assembly can pass through the wire entry notch and then pass through the wire entry port at the top, and then pass through the connection hole set on the shell module and connect to the PCB circuit board.

[0056] In the vehicle-mounted antenna provided in some embodiments of the present application, Figure 3 and Figure 4 As shown, the fixing module also includes a wire outlet fixing plug, which is provided with a wire outlet hole. The wire outlet fixing plug is arranged between the threaded fixing component and the PCB circuit board, and is used to fix the cable assembly through the wire outlet hole after the cable assembly passes through the wire inlet gap and the wire inlet.

[0057] In this embodiment, the fixing module also includes an outlet fixing plug, which fixes the cable assembly together through the outlet fixing plug and the threaded fixing assembly. The outlet fixing plug is installed between the threaded fixing assembly and the PCB circuit board. Therefore, the threaded fixing assembly is installed outside the housing module, and the outlet fixing plug is installed inside the housing module. The cable assembly passes through the threaded fixing assembly outside the housing module and then through the outlet fixing plug inside the housing module to connect to the PCB circuit board. The outlet fixing plug is provided with an outlet hole. The diameter of the outlet hole can be the same as or slightly smaller than the diameter of the cable assembly to fix the cable assembly after the cable assembly passes through the outlet fixing plug. It can be understood that the threaded fixing assembly is installed outside the housing module to fix the installation direction of the cable assembly, and the outlet fixing plug is installed inside the housing module to fix the position of the cable assembly. The combined action of the threaded fixing assembly and the outlet fixing plug greatly improves the reliability of the connection between the cable assembly and the PCB circuit board.

[0058] It can be understood that since the diameter of the wire outlet hole can be the same as or slightly smaller than the diameter of the cable assembly, the cable assembly is directly connected to the PCB circuit board after passing through the wire outlet hole. Therefore, when the installation direction of the cable assembly changes, it is only necessary to change the installation direction of the threaded fixing assembly. The installation direction of the wire outlet fixing plug remains unchanged and can also cooperate with the change of the installation direction of the cable assembly.

[0059] It can be understood that the outlet fixed wire plug is arranged between the threaded fixing assembly and the PCB circuit board, the cable assembly is connected to the PCB circuit board after passing through the connecting hole set on the shell module, and the fixing module is connected to the shell module. Therefore, the cable assembly can pass through the wire inlet notch and then through the wire inlet at the top, and then pass through the connecting hole set on the shell module and then through the wire outlet hole to connect to the PCB circuit board.

[0060] In the vehicle-mounted antenna provided in some embodiments of the present application, Figure 5 and Figure 6 As shown, the threaded fixing assembly includes an incoming wire insert and a nut unit. The nut unit is arranged at one end of the incoming wire insert away from the incoming wire port, and the other end of the incoming wire insert is connected to the outgoing wire fixing plug.

[0061] In this embodiment, the threaded fixing assembly includes a wire feed insert and a nut unit. The wire feed notch and the wire feed port are both arranged on the wire feed insert. The wire feed port is arranged at one end of the wire feed insert, and the other end is used to connect the nut unit, that is, the nut unit is arranged at the end of the wire feed insert away from the wire feed port. The nut unit is used to fix the wire feed insert by tightening the nut and the thread after the cable assembly is installed, thereby fixing the installation direction of the cable assembly, and a wire feed notch is set on one side of the wire feed insert. The diameter of the wire feed notch can be the same as the diameter of the cable assembly or slightly larger than the diameter of the cable assembly.

[0062] It can be understood that when the installation direction of the cable assembly needs to be changed, the installation direction of the wire inlet insert can be changed to match the change of the installation direction of the cable assembly. The wire inlet insert can be connected to the shell module by rotating the snap connection. When the installation direction of the cable assembly needs to be changed, the installation direction of the wire inlet insert can be changed by rotating the wire inlet insert and then fixedly connected to the shell module by snapping it.

[0063] The end of the incoming wire insert that is not connected to the nut unit is connected to the outgoing wire fixing plug. The incoming wire insert is provided with a buckle opening for fixing the outgoing wire fixing plug, and the outgoing wire fixing plug is provided with a buckle that cooperates with the buckle opening. The buckle on the outgoing wire fixing plug can pass through the buckle opening on the incoming wire insert and be connected to the incoming wire insert.

[0064] In another embodiment, when the vehicle antenna is installed, Figure 5 As shown, by adding a mounting plate, when installing the outlet wire fixing plug, the connection between the outlet wire fixing plug and the inlet wire insert can be initially fixed through the buckle card group mounting plate of the outlet wire fixing plug, which facilitates the subsequent installation of the nut unit.

[0065] In the vehicle-mounted antenna provided in some embodiments of the present application, the line inlet insert is detachably connected to the housing module, and the installation direction of the fixed module can be changed by replacing the line inlet insert with a different line inlet notch.

[0066] In this embodiment, the wire inlet insert is detachably connected to the shell module. When the installation direction of the cable assembly needs to be changed, the wire inlet insert can be removed and replaced with a wire inlet insert with a corresponding wire inlet notch according to the required installation direction of the cable assembly, thereby changing the installation direction of the fixed module.

[0067] In one embodiment, two different wire feeder inserts have different and opposite wire feeder notch directions.

[0068] In the vehicle-mounted antenna provided in some embodiments of the present application, Figure 7 and Figure 8 As shown, the nut unit includes a tooth washer, a nut and a fastening sleeve. A protrusion is provided inside the tooth washer for cooperating with the wire inlet notch to fix the direction of the tooth washer. The fastening sleeve is provided between the tooth washer and the nut to connect and fix the tooth washer and the nut.

[0069] In this embodiment, the nut unit includes a tooth washer, a nut, and a tightening sleeve, wherein a protrusion is provided inside the tooth washer for cooperating with the wire inlet notch of the wire inlet insert. The protrusion provided on the tooth washer cooperates with the wire inlet notch to fix the direction of the tooth washer, thereby fixing the entire nut unit. The protrusion provided on the tooth washer can match the size of the wire inlet notch so that the protrusion provided on the tooth washer can be inserted into the wire inlet notch to fix the direction of the tooth washer. In addition, the tooth washer is also provided with a notch corresponding to the protrusion, serving as an outlet for the cable assembly. The tightening sleeve is provided between the tooth washer and the nut, and the tightening sleeve is provided with a groove for cooperating with the clamping tooth washer and a threaded groove for cooperating with the clamping nut. The groove for cooperating with the clamping tooth washer and the threaded groove for cooperating with the clamping nut are located parallel to the upper and lower sides of the tightening sleeve, and the tooth washer and the nut can be connected to the tightening sleeve through the corresponding grooves.

[0070] Based on this, when installing the nut unit after the cable assembly and the wire entry insert are installed, the nut unit can be installed as a whole on the end of the wire entry insert away from the wire entry port, and then the nut unit can be pushed as a whole toward the wire entry port, so that the cable assembly is located in the notch set on the tooth gasket as the outlet of the cable assembly. At this time, the protrusion set on the tooth gasket can press against the cable assembly to further fix the position of the cable assembly.

[0071] In the vehicle-mounted antenna provided in some embodiments of the present application, the width of the wire entry notch is 21 mm.

[0072] The width of the cable entry notch is set to 21mm, which can adapt to more assembly conditions with different thickness requirements. Similarly, the width of the cable entry notch can also be set to other widths, depending on the size of the cable assembly.

[0073] In the vehicle-mounted antenna provided in some embodiments of the present application, Figure 1 、 Figure 2 and Figure 9 As shown, the housing module includes an outer cover, a base, and an outer gasket. The connection holes provided on the housing module include a first connection hole, a second connection hole, a third connection hole, and a fourth connection hole provided on the base, and an assembly hole provided on the outer gasket. The base is plug-connected to a corresponding protrusion provided on the outer gasket through the first connection hole, is threadedly connected to the outer cover through the second connection hole, and is threadedly connected to the PCB circuit board through the third connection hole. The cable assembly passes through the wire inlet notch, the wire inlet, the assembly hole, the fourth connection hole, and the wire outlet fixed plug before being connected to the PCB circuit board.

[0074] The base is arranged between the outer cover and the outer gasket, the PCB circuit board is arranged between the outer cover and the base, the antenna rod is connected to the outer cover, the wire outlet fixing plug is arranged on the base, and the threaded fixing component passes through the assembly hole and is arranged on the side of the base facing the outer gasket.

[0075] In this embodiment, the housing module includes an outer cover, a base, and an outer gasket. The outer cover and the outer gasket serve as the main outer shell of the vehicle-mounted antenna and can wrap around the PCB circuit board and the base. The base serves as a base for installing the PCB circuit board, and the PCB circuit board is fixedly installed in the main outer shell of the vehicle-mounted antenna formed by the outer cover and the outer gasket. Therefore, the base is installed between the outer cover and the outer gasket, and the PCB circuit board is installed between the outer cover and the base. In one embodiment, the installation order of the PCB circuit board, the outer cover, the base, and the outer gasket is outer gasket, base, PCB circuit board, and outer cover from bottom to top. In addition, since the antenna pole needs to face the outside world to receive wireless signals, the antenna pole cannot be set on the side of the outer gasket. Instead, the antenna pole is set on the side of the outer cover and connected to the outer cover to fix the antenna pole. The cable assembly passes through the outer gasket on the side of the outer gasket and then connects to the PCB circuit board.

[0076] In addition, the connection holes provided on the housing module include a first connection hole, a second connection hole, a third connection hole, a fourth connection hole provided on the base, and an assembly hole provided on the outer gasket. The outer cover is provided with a thread, and the outer gasket is provided with a plug-in protrusion. The base is plug-connected with the corresponding protrusion provided on the outer gasket through the first connection hole, is threadedly connected to the outer cover through the second connection hole, and is threadedly connected to the PCB circuit board through the third connection hole. The cable assembly is connected to the PCB circuit board after passing through the wire inlet notch, the wire inlet, the assembly hole, the fourth connection hole, and the wire outlet fixed plug. The third connection hole provided on the base can be a threaded hole, and a connection hole corresponding to the third connection hole is provided on the PCB circuit board. The base can be threadedly connected to the PCB circuit board through a metal pan head screw, and is threadedly connected to the outer cover through a self-tapping screw.

[0077] The fourth outlet hole provided on the base is used for the cable assembly to pass through the base. The fourth connecting hole corresponds to the outlet hole provided on the outlet fixing plug. The cable assembly passes through the fourth outlet hole and then through the outlet hole provided on the outlet fixing plug. The base is also provided with a mounting post, and the outlet fixing plug is also provided with a rivet hole. When the vehicle-mounted antenna is installed, the mounting post provided on the base cooperates with the rivet hole provided on the outlet fixing plug to fix the outlet fixing plug to the base by riveting.

[0078] Based on this, for example, when the vehicle-mounted antenna is installed, the antenna pole is connected to the outer cover, which can be connected by cooperating with the screw at one end of the antenna pole with the threaded hole provided on the outer cover. The outer cover is connected to the base through the second connecting hole on the base, the self-tapping screw and the self-tapping threaded hole on the outer cover, that is, the self-tapping screw passes through the second connecting hole on the base and is threadedly connected to the self-tapping threaded hole on the outer cover, so as to fix the outer cover and the base, and the base is then plug-connected with the corresponding protrusion on the outer gasket through the first connecting hole; inside the vehicle-mounted antenna, the base is connected to the PCB circuit board through the third connecting hole on the base, the metal pan head screw and the connecting hole provided on the PCB circuit board, that is, the metal pan head screw passes through the connecting hole provided on the PCB circuit board and is threadedly connected to the third connecting hole on the base, and the wire outlet is fixed with the wire plug. The outlet wire fixing plug is fixed to the base through the riveting hole and the mounting column provided on the base; the assembly hole provided on the outer gasket is used to install the threaded fixing component, that is, the threaded fixing component is provided on the side of the base facing the outer gasket after passing through the assembly hole. When the outer gasket is plugged into the base, the position of the assembly hole provided on the outer gasket corresponds to the position of the fourth connecting hole on the base and the position on the base for installing the threaded fixing component. Therefore, when the outer gasket is plugged into the base, the threaded fixing component is connected to the base through the assembly hole and installed and the threaded fixing component is preliminarily fixed. Then the cable assembly can be passed through the wire inlet gap, the wire inlet, the assembly hole, the fourth connecting hole and the outlet wire fixing plug and then connected to the PCB circuit board, and then the threaded fixing component is completely fixed. In this way, the assembly of the vehicle antenna is completed.

[0079] In the vehicle-mounted antenna provided in some embodiments of the present application, Figure 9 As shown, the housing module further includes a first sealing ring and a second sealing ring, the first sealing ring being arranged between the outer cover and the base, and the second sealing ring being arranged between the base and the outer gasket.

[0080] In this embodiment, a first sealing ring groove for accommodating the first sealing ring is provided on a side of the base that faces the outer cover. When the outer cover and the base are connected, the first sealing ring can be placed on the first sealing ring groove of the base, so that the first sealing ring is disposed between the outer cover and the base, thereby improving the sealing between the outer cover and the base.

[0081] A second sealing ring groove for placing the second sealing ring is provided on the side of the base facing the outer gasket. Before connecting the outer cover and the outer gasket, the second sealing ring can be placed on the second sealing ring of the base and then the outer cover and the outer gasket are connected. The second sealing ring is arranged between the base and the outer gasket. The area of ​​the assembly hole on the outer gasket is larger than the area of ​​the fourth connection hole on the base. Therefore, the second sealing ring can improve the isolation of the vehicle antenna from the external environment.

[0082] In this embodiment, the first sealing ring and the second sealing ring may be made of silicone rubber. By using the interference fit of the first sealing ring and the second sealing ring with silicone rubber, the vehicle antenna can achieve IP67 level waterproof and dustproof.
