Description

Technical Field

[0001] The present invention relates to the field of satellite navigation technology, in particular to a navigation and positioning device with a protective structure. Background Art

[0002] Navigation positioning is a technology that uses the Global Positioning System (GPS) and other related technologies to determine the precise location of an object or destination on the surface of the earth. Currently available navigation and positioning devices, such as navigation locators, mainly rely on the interaction between satellite signals, ground base stations and receivers. They calculate the distance by measuring the signal propagation time, thereby determining the precise location of a destination or an object on the earth, and guiding users to the destination along a preset route. They are widely used in automobile navigation, aviation and navigation, geological exploration, agricultural planting and other fields. However, since the navigation locator contains sophisticated electronic components and sensors, these components are sensitive to the external environment. Due to the wide range of usage scenarios of the navigation locator, it is necessary to design a series of protective structures on the outside of the navigation locator to protect the normal operation of the internal hardware of the navigator and extend its service life.

[0003] For example, a navigation and positioning device with a protective structure with announcement number CN220340405U, by providing a protective shell, a protective cover, a rubber plate, a rubber buffer sheet, a first damper, a first buffer spring, a second damper and a second buffer spring, facilitates all-round protection of the positioning device body and improves the overall protection effect.

[0004] In the above-mentioned device, although a series of protective structures are set on the outside of the navigation and locating instrument body to prevent the external environment from causing damage to the navigation and locating instrument body, the heat dissipation requirements of the navigation and locating instrument body are ignored. Although the heat dissipation holes and filters used can help the heat dissipation and dust prevention of the navigation and locating instrument to a certain extent, the passive heat dissipation method that relies solely on the heat dissipation holes cannot quickly and effectively dissipate the heat when the navigation instrument is working at high load or the external ambient temperature is high, thereby affecting the performance and stability of the navigation instrument. Moreover, the dustproof net will be clogged with dust and impurities after long-term use, thereby increasing the resistance to air circulation inside the equipment, thereby reducing the heat dissipation efficiency.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By starting the driving motor, one of the rotating gears A drives the exhaust fan to rotate through the connecting column A. When one of the rotating gears A is rotating, it will drive the other two rotating gears A to rotate synchronously through the synchronous belt. Then, the other two rotating gears A will drive the other exhaust fans to rotate synchronously through the connecting column A. Then, the rotation of multiple exhaust fans will draw hot air from the inside of the protective shell through the opening of the mounting shell A and discharge it to the outside, thereby strengthening the air circulation inside the protective shell, and then strengthening the heat dissipation efficiency of the navigation locator body, so that the navigation locator body can quickly and effectively discharge the heat emitted by the navigation locator body from the inside of the protective shell when working under high load or the external ambient temperature is high.

Then, the dustproof plate can be cleaned by the reciprocating brush plate to prevent the filter holes of the dustproof plate from being blocked by dust and impurities after long-term use, thereby increasing the air circulation resistance inside the equipment.

[0020] 3. While the two connecting slides move, the two pairs of card seats will also be driven to move synchronously. When the two pairs of card seats move, the rotating rod A connected by the rotation between each two card seats will be used to drive the two brush rollers to move synchronously. While the two rotating rods A are moving, the rotating gears B set at both ends of the two rotating rods A are respectively engaged with the two racks, thereby making the two rotating rods A drive the two brush rollers to rotate synchronously.

[0052] In the present embodiment, when the cover 10 and the protective shell 2 are closed, the movement of the cover 10 is limited by the limiting slide groove A9, and the tension of the stretching spring 1203 is used to ensure the distance between the cover 10 and the L-shaped hinge 1204, so that the cover 10 can be completely fitted to the opening of the protective shell 2. In this way, the navigation locator body 1 is prevented from being damaged by external environmental factors under the protection of the cover 10 and the protective shell 2. When it is necessary to check the condition of the navigation locator body 1 inside the protective shell 2, the cover 10 is pushed so that the protrusion on the outside of the cover 10 slides along the inner side of the limiting slide groove A9 and can be disengaged from the limiting slide groove A9. When the cover 10 slides, the limit rod B1201 and the block 1202 will slide on the inner side of the limit slot B12, and the block 1202 will pressurize the tension spring 1203 while sliding, causing the tension spring 1203 to contract. Then, after the protrusion of the cover 10 is disengaged from the limit slot A9, the cover 10 can be flipped by utilizing the hinge between the L-shaped hinge 1204 and the hinge frame 1205, thereby exposing the opening of the protective shell 2, so that the condition of the navigation locator body 1 inside the protective shell 2 can be checked, and the tension of the tension spring 1203 can make the cover 10 fit again with the L-shaped hinge 1204.

[0053] In summary, the working principle of the present invention is as follows:

[0054] First, when the navigation positioning device performs heat dissipation work locally, by starting the driving motor 308, one of the rotating gears A304 drives the exhaust fan 307 to rotate through the connecting column A306, and when one of the rotating gears A304 is rotating, it will drive the other two rotating gears A304 to rotate synchronously through the synchronous belt 305, and then, when the other two rotating gears A304 are rotating, they will drive the other exhaust fans 307 to rotate synchronously through the connecting column A306, and then with the rotation of multiple exhaust fans 307, hot air will be drawn from the inside of the protective shell 2 through the opening of the mounting shell A301, and then discharged to the outside, and new cold air will be drawn into the inside of the protective shell 2 through the opening of the mounting shell B401. , thereby enhancing the air circulation inside the protective shell 2, thereby enhancing the heat dissipation efficiency of the navigation and positioning instrument body 1 inside the protective shell 2, so that when the navigation and positioning instrument body 1 is working under high load or the external environment temperature is high, it can quickly and effectively discharge the heat emitted by the navigation and positioning instrument body 1 from the inside of the protective shell 2; and when the two rotating gears A304 rotate synchronously, the two driving gears A801 ​​will be driven to rotate synchronously through the two connecting columns B8, and then the two driving gears A801 ​​will mesh with the two first gears 702 when rotating, so that the two first gears 702 will drive the two second gears 703 to rotate synchronously through the two rotating rods B701, and the two second gears When 703 rotates, two of the third gears 704 are driven to rotate synchronously, and when two of the third gears 704 are rotated, the other two third gears 704 are driven to rotate synchronously through the two rotating rods C705, and then when the other two third gears 704 are rotated, they drive the two outer second gears 703 to rotate synchronously, and then the other two second gears 703 drive the other two first gears 702 to rotate synchronously through the other two rotating rods B701, and the other two first gears 702 are meshed with the two driving gears B803, so that the two driving gears B803 can drive the two rotating disks 410 to rotate synchronously through the two connecting columns B8, and while the two rotating disks 410 are rotating, through The sliding between the clamping column 409 and the limiting groove 408 enables the two connecting plates 407 to push the two connecting slides 405 to slide back and forth synchronously along the outer sides of the limiting columns 406 as the two rotating disks 410 rotate. While the two connecting slides 405 slide back and forth, they will also drive the brush plate 404 to move back and forth synchronously. Then, the dustproof plate 403 can be cleaned by the reciprocating brush plate 404 to prevent the filter holes of the dustproof plate 403 from being clogged by dust and impurities after long-term use, thereby increasing the air circulation resistance inside the equipment. The dust and impurities in the filter holes of the dustproof plate 403 will fall into the storage box 1301 through the inclined slot 402 after being cleaned by the brush plate 404.In this way, the dust and impurities cleaned by the brush plate 404 are collected. When the connecting slide 405 moves, the two pairs of card seats 4052 are also driven to move synchronously. When the two pairs of card seats 4052 move, the rotating rod A4054 connected between each two card seats 4052 is rotated, thereby driving the two brush rollers 4055 to move synchronously. When the two rotating rods A4054 move, the rotating gears B4056 set at both ends of the two rotating rods A4054 are respectively engaged with the two racks 4057, thereby making The two rotating rods A4054 drive the two brush rollers 4055 to rotate synchronously, and then the brush rollers 4055 absorb dust impurities through the fluff on the surface during the translational rotation, so that the dust impurities remaining in the air inside the installation shell B during the cleaning process of the dustproof plate 403 by the brush plate 404 can be cleaned, thereby preventing the residual dust impurities from entering the protective shell 2 and contacting the navigation locator body 1 when the brush plate 404 is cleaning the dustproof plate 403, and the two brush rollers 4055 move to either side of the installation shell B401 When the brush roller 4055 is disengaged from the inner side of the mounting shell B, the spring 4053 pushes the holder 4052 to push the brush roller 4055 to restore its initial position, so that the distance between the two brush rollers 4055 can be adjusted according to the reciprocating movement of the connecting slide 405. The moving distance can be changed and adjusted, so that the movement of the brush roller 4055 will not hinder the movement of the connecting slide 405, and the brush roller 4055 will contact the inner side of the mounting shell B while contacting the cleaning plate 5, and then the brush roller 4055 can be cleaned through the protrusion of the cleaning plate 5. When it is necessary to check the condition of the navigation locator body 1 inside the protective shell 2, the cover plate 10 is pushed to make the protrusion on the outside of the cover plate 10 slide along the inner side of the limiting slide groove A9, and then it can be disengaged from the limiting slide groove A9. When the cover 10 slides, the limit rod B1201 and the block 1202 will slide on the inner side of the limit slot B12, and the block 1202 will press the tension spring 1203 while sliding, so that the tension spring 1203 will shrink. Then, after the protrusion of the cover 10 is disengaged from the limit slot A9, the cover 10 can be flipped by the hinge between the L-shaped hinge 1204 and the hinge frame 1205, so that the opening of the protective shell 2 is exposed, so that the condition of the navigation locator body 1 inside the protective shell 2 can be checked. If the entire device needs to be moved and is bumped during transportation, the navigation locator body 1 will put pressure on the support plate 607.Then, when the support plate 607 is under pressure, the two pairs of hinges A606 and one end of the two pairs of adjustment plates 605 are hinged, and at the same time, the other ends of the two pairs of adjustment plates 605 push the two pairs of hinge seats 603 to move relative to each other on the outside of the limit rod A602. Then, when the two pairs of hinge seats 603 slide relative to each other, each two hinge seats 603 will exert pressure on the support spring 604, causing the support spring 604 to deform under force. Then, through the elasticity of the support spring 604, the navigation and positioning instrument body 1 can be buffered to a certain extent during the bumping process, thereby reducing the damage to the navigation and positioning instrument body 1 during the transportation of the equipment.
