Description

Technical Field

[0001] This utility model relates to the field of navigation technology, and in particular to an easy-to-clean front cover for a navigation device. Background Technology

[0002] In the use of in-vehicle navigation devices and portable navigators, the front cover is a core component that protects the display screen and ensures the clarity of information display. Its ease of cleaning directly affects the user experience and lifespan of the device.

[0003] Existing front covers are mostly made of acrylic, ordinary plastic or glass. In dry environments in vehicles (such as high temperature, air conditioning heating) or through touch and friction, static electricity is easily accumulated, which continuously attracts dust particles. In particular, road dust and fine particles from air conditioning vents are more likely to adhere to the screen, obstructing it and affecting information reading.

[0004] As for dust on the cover surface, the current mainstream cleaning methods still rely on manual operation: On the one hand, most users use paper towels to wipe it. The small hard particles (such as pulp impurities) contained in the wood pulp fibers of the paper towels are easy to rub against the cover surface (especially soft materials such as acrylic) during the wiping process, which will cause scratches on the cover surface and damage the light transmission over a long period of time; on the other hand, when wiping manually, fingers inevitably come into contact with the cover surface, which can easily leave fingerprints and oil stains, which need to be wiped repeatedly to remove, further increasing the cleaning steps and the risk of wear and tear on the cover. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an easy-to-clean front cover for navigation devices, solving the prominent problem of electrostatic dust accumulation on the front cover in existing technologies, and the technical problem that traditional paper towel wiping causes friction with the cover surface, resulting in scratches on the cover surface and affecting light transmission.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an easy-to-clean navigator front cover, including a navigator body, a front cover installed on the navigator body, a shell installed on the front of the navigator body and outside the front cover, a strip groove extending to its bottom on the shell, sliders symmetrically slidably arranged on the upper and lower sides of the strip groove, an electrostatic dust removal brush rotatably connected between two sliders, and a Velcro plate fixed to the other side between the two sliders, with cleaning cotton strips adhered to the Velcro plate, a paddle installed on the top slider, and an ion antistatic component provided in the strip groove to eliminate static electricity on the front cover and prevent dust adhesion.

[0007] A further improvement is that the electrostatic dust removal brush and the cleaning cotton strip are both at the same height as the front cover plate, and both the electrostatic dust removal brush and the cleaning cotton strip are attached to the surface of the front cover plate.

[0008] A further improvement is that the electrostatic dust removal brush includes a shaft and bristles, the shaft being made of polycarbonate material and the bristles being made of carbon fiber material.

[0009] A further improvement is that the front cover is made of acrylic sheet, and a fluorocarbon coating, an antistatic layer, and an organosilicon layer are sequentially arranged on the front cover.

[0010] A further improvement is that one side of the strip groove extends through the outer shell, and a plug-in groove is provided inside the strip groove, with a baffle plate slidingly installed inside the plug-in groove.

[0011] A further improvement is that the ion static eliminator includes an installation groove formed on the inner wall of the strip groove, an air duct is formed at the bottom of the installation groove, a rubber airbag is installed in the installation groove, an exhaust hole is formed at the bottom of the rubber airbag, and an ion rod is installed in the air duct.

[0012] A further improvement is that the rubber airbag protrudes into the strip groove, and the edge of the top slider has an arc-shaped structure.

[0013] By employing the above technical solution, this utility model provides an easy-to-clean front cover for a navigation device, which has at least the following beneficial effects: 1. This utility model uses a paddle to drive a slider to slide along a strip groove to one side, thereby driving an electrostatic dust removal brush to rotate and eliminate static electricity and remove dust from the front cover. Combined with cleaning cotton strips attached to the Velcro plate, the surface of the front cover is wiped clean, thus achieving rapid cleaning of dust on the front cover and avoiding fingerprint residue from manual wiping and scratches caused by wiping with paper towels.

[0014] 2. This utility model ionizes the air in the air duct by passing an ion rod through an electric current to generate positive and negative ions. Then, by moving the lever, the slider moves along the strip groove to one side. At this time, the slider squeezes the rubber air bag, thereby blowing the gas in the rubber air bag into the air duct through the exhaust hole, forming an ion wind that blows on the surface of the front cover plate, thereby neutralizing the static electricity on the surface of the front cover plate and achieving the effect of eliminating static electricity.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 Given the significant problem of electrostatic dust accumulation on the front cover of existing technologies, and the fact that traditional paper towel wiping causes scratches on the cover surface due to friction, affecting light transmission, this embodiment provides an easy-to-clean navigator front cover. This design removes static electricity from the front cover and allows for easy wiping, avoiding scratches caused by paper towel wiping that could impair information reading. Please refer to... Figures 1-5 The easy-to-clean navigator front cover includes a navigator body 1, a front cover 2 mounted on the navigator body 1, and a housing 3 mounted on the front of the navigator body 1 and outside the front cover 2. The housing 3 has a strip groove 4 extending to its bottom. Slider 5 is symmetrically slidably mounted on the upper and lower sides of the strip groove 4. An electrostatic dust removal brush 6 is rotatably connected between the two sliders 5, and a Velcro plate 7 is fixed to the other side between the two sliders 5. A cleaning cotton strip 8 is attached to the Velcro plate 7. A paddle 9 is mounted on the top slider 5. An ion antistatic component 10 is provided in the strip groove 4 to eliminate static electricity in the front cover 2 and prevent dust from adhering.

[0020] Specifically, the electrostatic dust removal brush 6 and the cleaning cotton strip 8 are both at the same height as the front cover plate 2, and both are attached to the surface of the front cover plate 2. Before using the navigator body 1, the lever 9 is turned to drive the slider 5 to slide along the strip groove 4 to one side, thereby driving the electrostatic dust removal brush 6 to rotate and remove static electricity and dust from the front cover plate 2. Together with the cleaning cotton strip 8 attached to the Velcro plate 7, the surface of the front cover plate 2 is wiped clean, thereby achieving quick cleaning of dust on the front cover plate 2 and avoiding fingerprints left by manual wiping, as well as scratches on the front cover plate 2 caused by wiping with paper towels.

[0021] Specifically, the electrostatic dust removal brush 6 includes a shaft 61 and bristles 62. The shaft 61 is made of polycarbonate material, while the bristles 62 are made of carbon fiber material. The carbon fiber bristles 62 have excellent conductivity, which can quickly neutralize the static electricity on the surface of the front cover plate 2. They also have high fiber strength and wear resistance, making them suitable for long-term use. The polycarbonate shaft 61 has high rigidity, wear resistance, and good insulation, which prevents the mistransfer of static electricity caused by the conductivity of the shaft 61. It is also lightweight. When the bristles 62 come into contact with the front cover plate 2, the reverse friction force generated can drive the electrostatic dust removal brush 6 to rotate as a whole to remove dust.

[0022] To reduce the electrostatic adsorption of dust and prevent the surface of the front cover plate 2 from being scratched and worn, the front cover plate 2 in this device is made of acrylic sheet, and a fluorocarbon coating, an antistatic layer, and an organosilicon layer are sequentially arranged on the front cover plate 2. The fluorinated polymer material in the fluorocarbon coating forms a dense film that is hydrophobic, oil-proof, and anti-aging, and can isolate dust adhesion. The antistatic layer reduces the static electricity on the surface of the front cover plate 2 and prevents dust adsorption. The organosilicon layer forms an elastic transparent protective film that is waterproof, mildew-proof, and resistant to friction and aging.

[0023] Since dust inevitably accumulates on the surface of the cleaning tampons 8 after long-term use, which may scratch the front cover plate 2, the device has a strip groove 4 that extends through the outer shell 3 on one side, and an insertion slot is provided in the strip groove 4. A baffle plate 11 is slidably installed in the insertion slot. Pull the baffle plate 11 out of the insertion slot, thereby sliding the slider 5 out of the strip groove 4, removing the dirty cleaning tampons 8 from the Velcro plate 7, and replacing it with a new cleaning tampons 8.

[0024] Example 2 To further remove static electricity from the surface of the front cover 2 and prevent dust from adhering to it during use, therefore, based on Embodiment 1, as follows: Figures 1-5As shown, the device is also equipped with an ion static eliminator 10. The ion static eliminator 10 includes a mounting groove 101 formed in the inner wall of the strip groove 4. An air duct 102 is formed at the bottom of the mounting groove 101. A rubber airbag 103 is installed in the mounting groove 101. An exhaust port 104 is arrayed at the bottom of the rubber airbag 103. An ion rod 105 is installed in the air duct 102. The ion rod 105 is energized by the vehicle control system, thereby ionizing the air in the air duct 102 to generate positive and negative ions. Then, the lever 9 is moved to drive the slider 5 to slide along the strip groove 4 to one side. At this time, the slider 5 squeezes the rubber airbag 103, thereby blowing the gas in the rubber airbag 103 into the air duct 102 through the exhaust port 104, forming an ion wind that blows on the surface of the front cover 2, thereby neutralizing the static electricity on the surface of the front cover 2 and achieving the static eliminator effect.

[0025] Specifically, the rubber airbag 103 protrudes into the strip groove 4, and the edge of the top slider 5 has an arc surface structure; thus, the slider 5 can squeeze out the airflow inside the rubber airbag 103, and the arc surface structure prevents the rubber airbag 103 from slipping during the squeezing process.
