Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] Please see Figures 1-4The present invention provides an embodiment of a four-channel vehicle-mounted radio data acquisition terminal, comprising an irregularly shaped stepped shell 1, a heat dissipation substrate 2, an RF isolation chamber 3, and a distributed temperature control system 7. The heat dissipation substrate 2 is fixed inside the irregularly shaped stepped shell 1. The right side of the heat dissipation substrate 2 is the RF area, and the left side is the electronic control area. The RF isolation chamber 3 is symmetrically distributed and fixed in the RF area. A signal processing unit 5 is provided inside the RF isolation chamber 3. A control chamber 6 is installed in the electronic control area of the heat dissipation substrate 2. The distributed temperature control system 7 is provided on the outer wall of the RF isolation chamber 3 and the control chamber 6.
[0025] In combination with the above structural features, when this utility model is in operation, the irregular stepped shell 1 has a protrusion on the right side to accommodate the radio frequency circuit, which is suitable for the narrow space of the vehicle and reduces the volume compared with the traditional rectangular shell. By setting a heat dissipation substrate 2 and cooperating with the distributed temperature control system 7, the temperature inside the radio frequency isolation chamber 3 and the control chamber 6 can be actively regulated. By setting the radio frequency isolation chamber 3 and cooperating with the cross-shaped shielding frame 4, the signal interference between different signal processing units 5 is reduced, resulting in good practical effect.
[0026] Please see Figures 1-4 The irregular stepped shell 1 has a heat dissipation area 11 at the bottom inside, a heat dissipation fan 111 at the end of the heat dissipation area 11, and heat dissipation grooves on the side wall of the heat dissipation area 11. The heat dissipation substrate 2 is fixed on the upper end of the heat dissipation area 11. The heat dissipation substrate 2 is made of thermally conductive material and has uniformly distributed thermally conductive fins 21 at its bottom. The thermally conductive fins 21 are located inside the heat dissipation area 11. The distributed temperature control system 7 includes a cooling chip 71 and a temperature sensor 72. The cooling chip 71 is in close contact with the outer wall of the radio frequency isolation chamber 3 and the control chamber 6. The temperature sensor 72 is installed inside the radio frequency isolation chamber 3 and the control chamber 6 and is signal connected to the control chamber 6. The heat dissipation substrate 2 has a wiring channel 22 inside, and the connecting wire of the temperature sensor 72 is embedded in the wiring channel 22.
[0027] In combination with the above structural features, when this utility model is working, active heat dissipation is achieved through the heat dissipation area 11 at the bottom of the irregular stepped shell 1, the heat-conducting fins 21 and the cooling fan 111 of the heat dissipation area 11. After the signal processing unit 5 and the control compartment 6 generate heat, the heat dissipation substrate 2 is a heat-conducting material, which can transfer the heat to the heat-conducting fins 21, and the airflow generated by the cooling fan 111 blows it away. At the same time, a distributed temperature control system 7 is set outside the radio frequency isolation compartment 3 and the control compartment 6. When the temperature sensor 72 detects that the temperature inside the compartment exceeds the preset threshold, it will actively start the cooling chip 71 to force the temperature inside the compartment to cool it down and avoid the temperature inside the compartment from being too high.
[0028] Please see Figures 1-4 The bottom of the irregular stepped shell 1 is provided with a shock-absorbing base plate 9. The shock-absorbing base plate 9 has a three-layer stacked structure, including the first layer: rubber layer, the second layer: honeycomb aluminum layer and the third layer: silicone layer.
[0029] Please see Figures 1-4 The signal processing unit 5 includes a motherboard 51 and a data acquisition module 52. The motherboard 51 and the data acquisition module 52 are respectively embedded in four independent radio frequency isolation chambers 3. A flexible contact 53 is provided between the motherboard 51 and the data acquisition module 52.
[0030] In combination with the above structural features, when this utility model is in operation, by setting a shock-absorbing base plate 9 with a three-layer shock absorption effect, the vibration and impact under vehicle operation are efficiently absorbed through the rubber layer, honeycomb aluminum layer and silicone layer, and with the elastic contact 53 with a high compensation function, the poor contact of the internal circuit caused by bumps is avoided.
[0031] Please see Figures 1-4 The radio frequency isolation chamber 3 is a copper-plated aluminum alloy cavity with an inner wall covered with a wave-absorbing material layer. The top of the chamber is equipped with a detachable metal cover plate 31. A cross-shaped shielding frame 4 is set between the radio frequency isolation chambers 3. The cross-shaped shielding frame 4 penetrates vertically through the heat dissipation substrate 2, physically separating the four sets of radio frequency isolation chambers 3.
[0032] In combination with the above structural features, when this utility model is in operation, by setting up a radio frequency isolation chamber 3 made of copper-plated aluminum alloy cavity and cooperating with a cross-shaped shielding frame 4, the signal interference between different signal processing units 5 is reduced.
[0033] Please see Figures 1-4 The right side of the irregular stepped shell 1 is stepped and protruded, and its transition surface is a slope. A dustproof interface 8 is provided on the slope, and the dustproof interface 8 is distributed in a diamond shape. A flip-type cover 81 is provided on its outer side, and the flip-type cover 81 is embedded with an EMI shielding mesh.
[0034] In combination with the above structural features, when this utility model is working, the dustproof interfaces 8 are distributed in a diamond shape and are far apart, which can reduce interference between lines. The flip-type cover 81 has an embedded EMI shielding mesh, which can reduce the entry of dust when not in operation.
[0035] Working principle: In use, this utility model utilizes an irregularly shaped stepped outer shell 1, with a protrusion on the right side to accommodate the radio frequency circuit, adapting to the confined space of a vehicle. Compared to a traditional rectangular shell, its volume is reduced. By incorporating a heat dissipation substrate 2 and a distributed temperature control system 7, the temperature within the radio frequency isolation chamber 3 and control chamber 6 is actively regulated. Furthermore, the radio frequency isolation chamber 3, combined with a cross-shaped shielding frame 4, reduces signal interference between different signal processing units 5, resulting in good practical performance. Specifically:
[0036] Active heat dissipation is achieved through the heat dissipation area 11 at the bottom of the irregularly shaped stepped outer shell 1, in conjunction with the heat-conducting fins 21 and the cooling fan 111 of the heat dissipation area 11. After the signal processing unit 5 and the control compartment 6 generate heat, the heat dissipation substrate 2, being a thermally conductive material, can transfer the heat to the heat-conducting fins 21, where it is blown away by the airflow generated by the cooling fan 111. Simultaneously, a distributed temperature control system 7 is installed outside the RF isolation compartment 3 and the control compartment 6. When the temperature sensor 72 detects that the temperature inside the compartment exceeds a preset threshold, it will actively activate the cooling chip 71 to forcibly cool the interior of the compartment, preventing excessive temperature buildup. The shock-absorbing base plate 9, with its three-layer shock absorption effect, efficiently absorbs vibrations and impacts from vehicle operation through rubber, honeycomb aluminum, and silicone layers. Combined with highly compensated elastic contacts 53, it prevents poor contact in the internal circuitry caused by bumps. The radio frequency isolation chamber 3, made of copper-plated aluminum alloy, along with the cross-shaped shielding frame 4, reduces signal interference between different signal processing units 5. The dustproof interfaces 8 are distributed in a diamond shape and spaced far apart, which reduces interference between lines. The flip-up cover 81 has an embedded EMI shielding mesh, which reduces dust entry when not in operation.
