Description

[0001] This invention relates to the field of vehicle-mounted BeiDou technology, specifically to a dustproof and heat dissipation shell structure for a vehicle-mounted BeiDou terminal. Background Technology

[0002] In the application scenarios of vehicle electronic devices, Beidou terminals are often installed on the outside of the vehicle or near the engine compartment. These environments are usually accompanied by a large amount of dust, sand and high-temperature airflow, which poses a serious threat to the stable operation of the precision electronic components inside the terminal. Without effective protection, the accumulation of dust will not only block the heat dissipation channel, but may also cause short circuits or signal interference, leading to a decline in equipment performance or even failure.

[0003] Traditional vehicle-mounted terminal protection devices mostly use simple sealing or passive heat dissipation. Although they can block dust intrusion to a certain extent, they neglect the internal air circulation, resulting in heat not being able to dissipate in time and forming a heat island effect. Fixed ventilation holes opened in order to take into account heat dissipation have instead become green channels for dust to enter, making it difficult to achieve an ideal balance between dust prevention and heat dissipation.

[0022] Example 1

[0023] Reference Figure 1-6 In the first embodiment of the present invention, a dustproof device 1 is provided, including a dustproof box 101, a dustproof cover 102 and a transparent observation window 103. The surface of the dustproof box 101 is fixedly connected to the surface of the dustproof cover 102, and the inner wall of the dustproof box 101 is fixedly connected to the surface of a plurality of transparent observation windows 103. A ventilation device 2 is provided on the dustproof box 101, and a heat dissipation device 3 is provided on the ventilation device 2. The ventilation device 2 is used to prevent the air inside the dustproof box 101 from not circulating, and the heat dissipation device 3 is used to dissipate the heat of the vehicle-mounted Beidou terminal.

[0024] Specifically, the dustproof device 1, by setting up a dustproof box 101 and a dustproof cover 102, solves the problem that the vehicle-mounted Beidou terminal is easily disturbed by dust and impurities in harsh environments, which can lead to damage to internal components or transmission failure. It places the terminal body and transmission components in a closed environment, effectively isolating external pollutants. At the same time, with the addition of a transparent observation window 103, the internal operating status can be intuitively monitored without disassembling the equipment, which facilitates daily maintenance and troubleshooting, ensures the stability of the terminal in dusty environments, and improves the maintainability and ease of operation of the equipment through visualization, thus achieving a combination of dust protection and operation monitoring.

[0025] Furthermore, when the vehicle-mounted Beidou terminal needs dust protection and heat dissipation, the terminal is first placed in the dustproof box 101. The surface of the dustproof box 101 is fixed with a dustproof cover 102 to protect the transmission components and prevent dust and impurities from entering and affecting the transmission quality. In addition, the surface of the dustproof box 101 is provided with a transparent observation window 103 to facilitate the staff to observe the internal situation. If ventilation of the dustproof box 101 is required, the double-head motor 201 fixed on the surface of the dustproof box 101 is started. The ventilation device 2 prevents the air inside the dustproof box 101 from not circulating, and the heat dissipation device 3 blows away the heat of the vehicle-mounted Beidou terminal.

[0026] Example 2

[0027] In a second embodiment of the present invention, a ventilation device 2 is provided, comprising a dual-head motor 201, a bevel gear set 202, a ventilation plate 203, a ventilation fan 204, and a ratchet set 205. The output ends of the dual-head motor 201 are fixedly connected to the inner walls of the two bevel gear sets 202. The output ends of the bevel gear sets 202 are rotatably connected to the inner wall of the ventilation plate 203. The surface of the ventilation plate 203 is rotatably connected to the surface of the ventilation fan 204. The ratchet set 205 is disposed at the output end of the bevel gear set 202. The surface of the dual-head motor 201 is fixedly connected to the outer surface of the dustproof box 101. The output end of the bevel gear set 202 is fixedly connected to the input end of the ratchet set 205. Both the bevel gear set 202 and the ratchet set 205 are disposed inside the dustproof cover 102. The surface of the ventilation plate 203 is fixedly connected to the inner wall of the dustproof box 101. The surface of the ventilation fan 204 is rotatably connected to the inner wall of the dustproof box 101.

[0028] Specifically, the ventilation device 2, through the cooperation of the dual-head motor 201 and the bevel gear set 202, effectively solves the problems of poor air circulation and heat accumulation in the sealed dustproof box 101 of the vehicle-mounted Beidou terminal. The dual-head motor 201 drives the ventilation fans 204 on both sides to operate synchronously, which can quickly form strong convection in the box and improve the internal heat dissipation efficiency. At the same time, with the ventilation plate 203 with ventilation holes, it can effectively block the entry of external dust and impurities while ensuring efficient air exchange. In addition, the ratchet set 205 set at the output end of the bevel gear set 202 uses transmission to transmit power and provide power for the subsequent cleaning of the heat dissipation plate 401.

[0029] Furthermore, if ventilation is required for the dust box 101, the dual-head motor 201 fixed on the surface of the dust box 101 is started. The output ends on both sides of the motor rotate forward, driving the fixed bevel gear set 202 to mesh synchronously and drive the ventilation fan 204 fixed at the output end of the bevel gear set 202 to rotate synchronously, accelerating the airflow inside the dust box 101. A ventilation plate 203 is fixed on the dust box 101, and ventilation holes are opened on the plate surface. While forming strong convection, it prevents impurities from entering. A ratchet set 205 is fixed at the other end of the bevel gear set 202 to provide power for subsequent heat dissipation and cleaning.

[0030] Example 3

[0031] A third embodiment of the present invention provides a heat dissipation device 3 comprising a driving worm gear 301, a driven worm wheel 302, a connecting rod 303, a driving bevel gear 304, a transmission bevel gear 305, and louvers 306. The tooth surfaces of the driving worm gear 301 mesh with the tooth surfaces of the driven worm wheel 302. The lower end of the driven worm wheel 302 is fixedly connected to the upper end of the connecting rod 303. The surface of the connecting rod 303 is fixedly connected to the input ends of the four driving bevel gears 304. The tooth surfaces of the driving bevel gears 304 mesh with the tooth surfaces of the transmission bevel gears 305. Gear 305 is meshed with the tooth surface, and the output end of the transmission bevel gear 305 is fixedly connected to the surface of the louver 306. A cleaning device 4 is provided on the heat dissipation device 3. The cleaning device 4 includes a heat dissipation plate 401, a cleaning brush 402, a reciprocating screw 403, a driven bevel gear 404, a mating bevel gear 405, and a stroke rod 406. The surface of the heat dissipation plate 401 is slidably connected to the surface of the cleaning brush 402, and the inner wall of the cleaning brush 402 is threadedly connected to the surface of the reciprocating screw 403. The end of the 03 is fixedly connected to the output end of the driven bevel gear 404. The tooth surface of the driven bevel gear 404 meshes with the tooth surface of the mating bevel gear 405. The stroke rod 406 is located at the lower end of the cleaning brush 402. The output end of the ratchet assembly 205 is fixedly connected to the surface of the driving worm gear 301. Both the driving worm gear 301 and the driven worm gear 302 are located inside the dust cover 102. The surface of the connecting rod 303 is rotatably connected to the inner wall of the dust cover 102. The surface of the louver 306 is connected to the inner wall of the dust box 101. The sliding groove is rotatably connected, and the input end of the bevel gear 405 is fixedly connected to the surface of the driving worm gear 301. The surface of the heat sink 401 is fixedly connected to the inner wall of the dustproof box 101. The surface of the reciprocating screw 403 is rotatably connected to the inner wall of the dustproof cover 102. The lower inner wall of the cleaning brush 402 is slidably connected to the surface of the stroke rod 406. The surface of the stroke rod 406 is fixedly connected to the inner wall of the dustproof cover 102. The driven bevel gear 404 and the mating bevel gear 405 are both located inside the dustproof cover 102.

[0032] Specifically, the heat dissipation and cleaning device 4 solves the problems of heat accumulation in the vehicle-mounted Beidou terminal in a closed and dust-proof environment and the easy clogging of heat dissipation components by dust. By using the reverse rotation of the motor and the unidirectional transmission characteristics of the ratchet group 205, ventilation and cleaning switching are realized. This structure can not only drive the louvers 306 to rotate to assist air convection, but also drive the cleaning brush 402 to scrape the heat dissipation plate 401 back and forth, effectively preventing the increase in thermal resistance caused by dust accumulation, ensuring the continuous heat dissipation efficiency of the equipment under harsh working conditions, reducing the frequency and difficulty of manual maintenance, and improving the stability and service life of the terminal operation.

[0033] Furthermore, heat dissipation plates 401 are fixed on both sides of the dust box 101 to assist in heat dissipation and prevent heat concentration from affecting the vehicle-mounted Beidou terminal. When it is necessary to clean the heat dissipation plates 401, the output ends of the dual-head motor 201 reverse, driving the bevel gear set 202 to mesh in the opposite direction, causing the ventilation fan 204 to reverse and blow air outward. At the same time, with the one-way transmission of the ratchet set 205, the active worm gear 301 fixed at the output end is driven to mesh with the transmission worm wheel, thereby driving the connecting rod 303 fixed at the lower end of the transmission worm wheel to rotate. Multiple active bevel gears 304 are fixed on the surface of the connecting rod 303. As the connecting rod 303 rotates, it drives the corresponding transmission bevel gears. When gear 305 meshes, the louver 306 fixed at the output end of the transmission bevel gear 305 rotates along the groove on the inner wall of the dustproof box 101. When the driving worm gear 301 rotates, the bevel gear 405 fixed to it rotates accordingly and meshes with the driven bevel gear 404, driving the reciprocating screw 403 fixed at the output end of the driven bevel gear 404 to rotate synchronously. The screw has a reciprocating thread on its surface. When the screw rotates, the cleaning brush 402 that is threaded to it moves axially back and forth to clean the surface of the heat sink 401. The lower end of the cleaning brush 402 slides with the stroke rod 406 to ensure smooth movement and prevent deviation.

[0034] Working principle: When the vehicle-mounted Beidou terminal needs dust protection and heat dissipation, it is first placed inside the dustproof box 101. A dust cover 102 is fixed to the surface of the dustproof box 101 to protect the transmission components and prevent dust and impurities from entering and affecting the transmission quality. In addition, a transparent observation window 103 is provided on the surface of the dustproof box 101 to facilitate the observation of the internal conditions by the staff. If ventilation is required for the dustproof box 101, the dual-head motor 201 fixed to the surface of the dustproof box 101 is started. The output ends on both sides of the motor rotate forward, driving the fixed bevel gear set 202 to mesh synchronously. The combined transmission causes the ventilation fan 204, fixed at the output end of the bevel gear set 202, to rotate synchronously, accelerating the airflow inside the dustproof box 101. A ventilation plate 203 is fixed on the dustproof box 101, with ventilation holes on its surface. This creates strong convection while preventing impurities from entering. A ratchet set 205 is fixed to the other end of the bevel gear set 202, providing power for subsequent heat dissipation and cleaning. Heat dissipation plates 401 are fixed on both sides of the dustproof box 101 to assist in heat dissipation and prevent heat concentration from affecting the vehicle-mounted Beidou terminal. When cleaning the heat dissipation plates 401 is required, the dual... The output ends of the head motor 201 reverse, driving the bevel gear set 202 to mesh in the opposite direction, causing the ventilation fan 204 to reverse and blow air outwards. Simultaneously, through the unidirectional transmission of the ratchet set 205, the driving worm gear 301 fixed at the output end meshes with the transmission worm wheel, thereby driving the connecting rod 303 fixed at the lower end of the transmission worm wheel to rotate. Multiple driving bevel gears 304 are fixed to the surface of the connecting rod 303. As the connecting rod 303 rotates, it drives the corresponding transmission bevel gear 305 to mesh, causing the louvers 306 fixed at the output end of the transmission bevel gear 305 to... As the active worm gear 301 rotates along the groove on the inner wall of the dustproof box 101, the bevel gear 405 fixed to it rotates accordingly and meshes with the driven bevel gear 404, driving the reciprocating screw 403 fixed at the output end of the driven bevel gear 404 to rotate synchronously. The screw has a reciprocating thread on its surface. When the screw rotates, the cleaning brush 402 that is threaded to it moves axially back and forth to clean the surface of the heat sink 401. The lower end of the cleaning brush 402 slides with the stroke rod 406 to ensure smooth movement and prevent deviation.

[0035] In summary, the combination of components such as a dual-head motor, bevel gear set, ratchet set, worm gear and reciprocating screw achieves the effects of air circulation, heat dissipation and automatic reciprocating cleaning of the heat sink surface inside the dustproof box.
