[0028] Some embodiments of the present application are further described in detail below in conjunction with the accompanying drawings.
[0029] See also Figure 1 The present application proposes a GPS device, which includes a GPS antenna, a GPS module and a GPS signal improvement device, wherein the GPS signal improvement device is electrically connected between the GPS antenna and the GPS module.
[0030] In the present application, the GPS signal improvement device is used to receive the signal sent back by the GPS antenna, and transmit the signal to the GPS module after enhancing, amplifying and filtering, so that the GPS module can obtain a GPS signal of sufficient strength. In addition, the GPS signal improvement device can also receive power from the GPS module and transmit power to the GPS antenna at the same time to ensure the stable operation of each module of the GPS device. In the present application, the GPS signal improvement device can be set outside the GPS device or built into the GPS device, and the present application does not limit this.
[0031] See also Figure 1 and Figure 2The GPS signal improvement device proposed in the present application includes a connector component, a signal amplifier component and a debugging component. The connector component includes a first connector and a second connector electrically connected to the first connector. The first connector is used to receive the signal returned by the GPS antenna, and the second connector is used to electrically connect to the GPS module; the signal amplifier component is arranged between the first connector and the second connector, and the signal amplifier component is used to amplify the GPS signal; the debugging component is arranged between the first connector and the second connector, and the debugging component includes a plurality of debugging modules arranged at intervals, and each debugging module is used to debug the input end matching and output end matching of the signal amplifier component respectively.
[0032] The first connector is electrically connected to the GPS antenna and is used to receive the signal transmitted back by the GPS antenna. In some embodiments, the first connector can be a radio frequency IPEX socket produced by I-PEX. Similarly, in some embodiments, the second connector can also be a radio frequency IPEX socket.
[0033] The signal amplifier component is arranged between the first connector and the second connector, and is used to enhance and amplify the GPS signal, so as to amplify the relatively weak GPS signal received by the first connector into a GPS signal with a certain strength. The signal amplifier component can be set to one or more. When it is set to more than one, the GPS signal can be amplified in multiple stages.
[0034] The debugging component includes a plurality of debugging modules, which can perform electrical signal debugging so that the input and output signals of the signal amplifier component can be transmitted smoothly, ensuring the stable operation of itself and subsequent components. In some embodiments, a π-shaped matching circuit can be provided on the debugging module, which can provide an appropriate load to protect each circuit element from damage by excessive voltage or current, and keep it in a safe and stable state at the working point.
[0035] Therefore, the signal amplifier component of the embodiment of the present application can enhance and amplify the GPS signal transmitted back by the GPS antenna, and even when the signal received by the GPS antenna is relatively weak, it can ensure that the GPS module can receive a GPS signal with a certain strength to support the normal operation of the GPS device, thereby effectively improving the signal reception performance of the GPS device. In addition, the debugging component of the embodiment of the present application can also debug the input and output ends of the signal amplifier component, effectively ensuring the normal operation of the GPS signal improvement device and improving the working stability of the GPS device.
[0036] See also Figure 2 In some embodiments, the signal amplifier component includes a first signal amplification module and a second signal amplification module, wherein the input and output ends of the first signal amplification module are respectively connected to the debugging module.
[0037] In these embodiments, both the first signal amplification module and the second signal amplification module have a signal amplification function, which can realize two-stage enhanced amplification of the GPS signal, greatly improving the signal enhanced amplification capability of the GPS signal improvement device. In addition, the input and output ends of the first signal amplification module are respectively connected to the debugging module to facilitate debugging of the input and output signals of the first signal amplification module, which is conducive to improving the working stability of the first signal amplification module.
[0038] Furthermore, in some embodiments, the input and output ends of the second signal amplifying module are also respectively connected to the debugging module, thereby further improving the working stability of the second signal amplifying module.
[0039] In some embodiments, the first signal amplification module is provided with a signal amplification circuit and a voltage adjustment circuit (eg Figure 3 shown).
[0040] It can be understood that the signal amplification circuit can be used for enhanced amplification of GPS signals, and the voltage adjustment circuit can adjust the working voltage of the first signal amplification module. When the input voltage provided by the GPS module is unstable, the voltage adjustment circuit can adjust the working voltage of the first signal amplification module to maintain stable operation, thereby improving the working stability of the first signal amplification module, which is beneficial to improving the working stability of the GPS signal improvement device.
[0041] Furthermore, in some embodiments, the second signal amplification module is provided with a signal amplification circuit and a voltage adjustment circuit, so that the second signal amplification module can be ensured to operate under stable voltage conditions, which is beneficial to improving the working stability of the second signal amplification module, thereby further improving the working stability of the GPS signal improvement device.
[0042] See also Figure 2 In some embodiments, the GPS signal improvement device further includes a filter, which is disposed between the debugging module and the first connector, and is used to filter out signal interference. Thus, the filter can effectively filter out foreign signal interference, which is beneficial to improving the transmission quality of the GPS signal, thereby improving the operating stability of the GPS signal improvement device.
[0043] In some embodiments, at least one debugging module is disposed between the filter and the first connector, and electrically connects the filter and the first connector.
[0044] By providing a debugging module between the filter and the first connector, it is possible to ensure that the GPS signal input to the filter can be effectively debugged to match the input end of the filter, thereby improving the working stability of the filter.
[0045] In some embodiments, the GPS signal improvement device further includes a printed circuit board and a mounting assembly, on which a connector assembly, a signal amplifier assembly and a debugging assembly are arranged; the mounting assembly is used to install the printed circuit board on the GPS device.
[0046] In the present application, the connector assembly, signal amplifier assembly and debugging assembly can be centrally arranged on a printed circuit board, which not only facilitates the electrical connection between the various components, but also helps to improve the structural integration of the GPS signal improvement device, thereby reducing the volume of the GPS signal improvement device.
[0047] The mounting assembly is used to mount the printed circuit board on the GPS device, and the mounting assembly can be a variety of structures, such as a snap-on structure or an adhesive structure, etc. For example, in the present application, the mounting assembly can be a double-sided adhesive tape, so that the printed circuit board can be directly bonded to the GPS device, simplifying the connection method of the GPS signal improvement device, which is conducive to reducing the difficulty of installation, thereby reducing the manufacturing cost.
[0048] According to the embodiments of the present application as above, these embodiments do not describe all the details in detail, nor do they limit the present application to only specific embodiments. Obviously, according to the above description, many modifications and changes can be made. Without departing from the scope of the present application, various improvements can be made to it and the components therein can be replaced with equivalents.
