[0002] A navigation signal analyzer receiver is a specialized device used to receive, process, and analyze signals from satellite navigation systems (such as GPS, BeiDou, and GLONASS). It is primarily used for signal quality assessment, system performance testing, anti-interference research, and navigation algorithm development. Its core functions include signal acquisition, tracking, decoding, measurement, and data analysis and visualization.

[0003] The navigation signal analysis receiver consists of an antenna, radio frequency (RF) front-end, digital signal processor (DSP), baseband processing unit, memory and storage, user interface, power management module, and various interfaces. The antenna captures satellite signals, the RF front-end performs preliminary amplification and filtering, the DSP handles complex signal processing tasks, and the baseband processing unit completes positioning calculations. This receiver supports multi-system compatibility, provides high-precision positioning and real-time data analysis capabilities, and is widely used in scientific research, education, engineering surveying, transportation, and logistics. Its flexible interfaces and powerful data processing capabilities make it an ideal tool for precision navigation and positioning. The effective integration of these components ensures efficient and accurate navigation signal processing and analysis.

[0004] During use, navigation signal analyzers generate a lot of heat inside their housings. Existing navigation signal analyzers typically use cooling fans inside the housings for heat dissipation. While this is effective, the devices are bulky, inconvenient to operate, and affect performance. Utility Model Content

[0005] The purpose of this invention is to solve the problem of large housing volume in the prior art, which makes operation inconvenient, and to propose a navigation signal analysis receiver.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A navigation signal analysis receiver includes a housing and a circuit board fixedly disposed within the housing. A heat sink is fixedly disposed at the top of the housing. The soldering surface of the circuit board abuts against the inner wall of the heat sink. A plurality of elongated heat dissipation grooves are formed on the outer wall of the heat sink, and the heat dissipation grooves extend along the long side of the heat sink.

[0007] To facilitate battery support, preferably, a rear cover is detachably provided at the bottom of the housing, a power compartment is fixedly provided inside the rear cover, and a battery is slidably provided inside the power compartment. A power receiving plate is fixedly provided on the circuit board, and an elastic conductive plate is fixedly provided on the power receiving plate, with the battery contacts abutting against the elastic conductive plate.

[0008] To facilitate battery installation and removal, a mounting groove is provided at one end of the housing, which is connected to the power supply compartment, and an end cap is detachably installed in the mounting groove.

[0009] To ensure a reliable connection between the battery and the elastic conductive plate, an elastic pad is further fixedly provided on the inner wall of the end cap, and the elastic pad abuts against the end of the battery away from the contact point.

[0010] Furthermore, a guide block is fixedly provided on the inner wall of the power compartment, and a guide groove is provided on the battery shell, with the guide block and the guide groove being slidably connected.

[0011] Preferably, the shell is made of magnesium-aluminum alloy.

[0012] Compared with the prior art, the present invention provides a navigation signal analysis receiver, which has the following advantages: 1. This navigation signal analyzer receiver has a heat sink fixed inside the housing. The back of the circuit board is pressed against the inner wall of the heat sink, which can dissipate heat to the outside through the heat sink. Multiple heat dissipation grooves are opened on the outer wall of the heat sink, which can increase the heat dissipation area of ​​the heat sink, further improve the heat dissipation effect, and help reduce the overall size of the housing, making it easier to operate and use, and improving the user experience. 2. This navigation signal analysis receiver, by fixing a guide block in the power compartment and opening a guide groove on the battery casing, can not only guide the battery to ensure that the battery contacts are correctly connected to the elastic conductive plate, but also prevent the battery from being reversed during installation, thus avoiding affecting normal use.

[0013] All parts not mentioned in this device are the same as or can be implemented using existing technology. This utility model has a heat sink fixedly installed inside the housing. The back of the circuit board is pressed against the inner wall of the heat sink, so that heat can be dissipated to the outside through the heat sink.

[0018] Example: Reference Figures 1-4A navigation signal analysis receiver includes a housing 1 made of magnesium-aluminum alloy, which has low density, is easy to carry, effectively suppresses external electromagnetic interference (EMI), improves signal stability, and has high thermal conductivity, helping to dissipate heat from the inner wall. The housing 1 also includes a circuit board 101 fixedly disposed within it. The circuit board 101 is electrically connected to modules such as an antenna, an RF front-end, a digital signal processor (DSP), a baseband processing unit, memory and storage, a user interface, a power management module, and various interfaces. A heat sink is fixedly disposed at the top of the housing 1, integrally formed with the housing 1 and made of the same material. Made of magnesium-aluminum alloy, the soldering surface of the circuit board 101 abuts against the inner wall of the heat sink, which is the back of the circuit board 101. Multiple elongated heat dissipation grooves 102 are formed on the outer wall of the heat sink. The heat dissipation grooves 102 extend along the long side of the heat sink and are equidistantly distributed along the short side of the heat sink. There are two to thirty heat dissipation grooves 102. Here, we prefer twenty-one. The multiple heat dissipation grooves 102 make the outer wall of the heat sink approximately fixed with multiple heat dissipation fins, which can increase the heat dissipation area of ​​the heat sink and improve the heat dissipation effect. At this time, the volume of the housing 1 can be appropriately reduced for convenient operation.

[0019] In use, by fixing a heat sink plate inside the housing 1 and pressing the back of the circuit board 101 against the inner wall of the heat sink plate, heat can be dissipated to the outside through the heat sink plate. Multiple heat dissipation grooves 102 are provided on the outer wall of the heat sink plate, which can increase the heat dissipation area of ​​the heat sink plate, further improve the heat dissipation effect, and help reduce the overall volume of the housing 1, making it convenient to operate and use, and improving the user experience.

[0020] Reference Figures 2-4 A rear cover 2 is detachably installed at the bottom of the housing 1. A fixing groove 104 is provided at the bottom of the housing 1, and the rear cover 2 is fixed in the fixing groove 104 with screws. The material of the rear cover 2 is aluminum alloy or plastic. Here, we prefer plastic, which can appropriately reduce the overall weight of the device and improve the performance. A power compartment 201 is fixedly installed inside the rear cover 2. The power compartment 201 is located inside the housing 1, and the battery 4 is slidably installed inside the power compartment 201. A power receiving plate 5 is fixedly installed on the circuit board 101, and an elastic conductive plate 501 is fixedly installed on the power receiving plate 5. The contacts of the battery 4 abut against the elastic conductive plate 501. A charging interface for charging the battery 4 is fixedly installed on the circuit board 101. In use, by removing the rear cover 2 from the housing 1 and fixing the power compartment 201 inside the rear cover 2, it is convenient to support and install the battery 4, thus improving the performance.

[0021] Reference Figure 1 , Figure 3 and Figure 4An installation groove 103 is provided at one end of the housing 1, which is connected to the power compartment 201. An end cover 3 is detachably installed in the installation groove 103. Here, the end cover 3 is preferably fixed in the installation groove 103 with screws, and an elastic pad 301 is fixedly installed on the inner wall of the end cover 3. The elastic pad 301 abuts against the end of the battery 4 away from the contact point, which can fix the battery 4 and prevent it from sliding. In use, by providing an installation groove 103 on the housing 1 that is connected to the power compartment 201, the end cover 3 is detached from the installation groove 103. After removing the end cover 3, the battery 4 can slide from the power compartment 201 to the installation groove 103, which realizes the removal of the battery 4 and facilitates its use.

[0022] Reference Figure 3 and Figure 4 A guide block 202 is fixedly installed on the inner wall of the power compartment 201, and a guide groove is opened on the outer shell of the battery 4. The guide block 202 is slidably connected to the guide groove. In use, by fixing the guide block 202 in the power compartment 201 and opening the guide groove on the outer shell of the battery 4, the battery 4 can be guided to ensure that the contacts of the battery 4 are correctly connected to the elastic conductive plate 501. It can also prevent the battery 4 from being reversed during installation, thus avoiding the battery 4 being upside down and affecting normal use.
