Description

Dustproof construction of on-vehicle HUD

Technical Field

The invention relates to the field of HUD devices, in particular to a dustproof structure of a vehicle-mounted HUD.

Background

Head Up Displays (HUDs), which are flight aids used on aircraft; by "heads-up" is meant that the pilot is able to see the important information he needs without lowering his head. With the development of smart cars, HUDs are beginning to be applied in the automotive field. The HUD projects important information about the vehicle onto a piece of glass by using the principle of optical reflection. The glass is positioned between the steering wheel and the windshield of the automobile, the height of the glass is approximately horizontal to the eyes of a driver, and projected characters and images are adjusted to be above the distance of infinite focal distance.

The cmbiner component is used as a display mechanism of the HUD, and needs to extend out when the HUD is opened and retract when the HUD is closed; the existing HUD adopts a mode of rolling a curtain to seal a windshield glass opening in the aspects of dust prevention and foreign matter prevention, when the HUD is used, a curtain seal is opened, a combiner component extends out in a turnover mode, a large gap is left, and the vehicle-mounted HUD is large in size; and dust and foreign matter easily fall into the HUD.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides the dustproof structure of the vehicle-mounted HUD, the opening size of the dustproof cover can be adjusted by changing the sealing into the mode that the motor drives the dustproof cover and changing the combiner component of the vehicle-mounted HUD into the mode of ascending, descending and exiting, the vehicle-mounted HUD can be opened seamlessly, and the effects of reducing the size of the vehicle-mounted HUD and preventing dust are achieved.

In order to achieve the technical effects, the invention adopts the following scheme: a dustproof structure of a vehicle-mounted HUD comprises a combiner component, a motor and a dustproof cover, wherein the combiner component, the motor and the dustproof cover are arranged inside the vehicle-mounted HUD; the device also comprises a vertical guide rail, a screw rod, a nut, a hexagonal shaft, a bevel gear, a locking arm and a connecting rod; the nut is arranged at the lower part of the combiner component, the screw rod is arranged in the vertical direction, and the surface of the screw rod is provided with a thread and penetrates through the nut; the hexagonal shaft penetrates through the bevel gear, and driving gears are arranged at two ends of the hexagonal shaft; the bevel gear and the screw rod are connected with the motor through gears; the two ends of the hexagonal shaft are connected with the locking arms; the connecting rod is fixed on the outer side of the vertical guide rail through a fulcrum; the locking arm controls the link; the top end of the connecting rod is connected with the dustproof cover; the combiner component is provided with a transverse positioning shaft, and driving gears are arranged on two sides of the combiner component; the two ends of the positioning shaft are provided with rollers; the driving gear and the positioning shaft of the combiner assembly are arranged in the vertical guide rail.

Further, the vertical guide rails comprise a first vertical guide rail and a second vertical guide rail; sawteeth corresponding to the driving gear of the combiner component are arranged inside the vertical guide rail.

When the system is opened, the motor drives the screw rod and the hexagonal shaft simultaneously, so that the combiner component and the dust cover move simultaneously, the combiner component ascends, and the dust cover is opened. And similarly, when the combiner component descends, the dust cover is closed.

Through the setting, when the vehicle-mounted HUD is started, the motor drives the connecting rod to pull open the dustproof cover and simultaneously rotate the screw rod to jack up the windshield glass of the vehicle-mounted HUD; the seamless opening and closing of the vehicle-mounted HUD are realized, and the effects of reducing the size, preventing dust and foreign matters are achieved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1:

as shown in fig. 1 and 3, the dustproof structure of the vehicle-mounted HUD comprises a combiner component, a motor 1 and a dustproof cover 13, wherein the combiner component is arranged inside the vehicle-mounted HUD; the device also comprises a vertical guide rail 2, a screw rod 3, a nut 4, a hexagonal shaft 5, a bevel gear 6, a locking arm 7 and a connecting rod 8; the nut 4 is arranged at the lower part of the combiner component, the screw rod 3 is arranged in the vertical direction, and the surface of the screw rod is provided with threads and penetrates through the nut 4; the hexagonal shaft 5 passes through the bevel gear 6, and the two ends are provided with driving gears 51; the bevel gear 6 and the screw rod 3 are connected with the motor 1 through a gear 9; two ends of the hexagonal shaft 5 are connected with locking arms 7; the connecting rod 8 is fixed at the outer side of the vertical guide rail 2 through a fulcrum; the locking arm 7 controls the link 8; the top end of the connecting rod 8 is connected with a dust cover 13. As shown in fig. 2, the combiner component is provided with a transverse positioning shaft 10, and driving gears 11 are arranged on two sides of the combiner component; the two ends of the positioning shaft are provided with rollers 12; the driving gear 11 and the positioning shaft 12 of the combiner unit are arranged in the vertical guide rail 7.

Specifically, the vertical guide rail 2 includes a first vertical guide rail and a second vertical guide rail; the vertical guide rail 2 is internally provided with saw teeth corresponding to the driving gear 11 of the combiner unit.

When the system is opened, the motor 1 drives the screw rod 3 and the hexagonal shaft 5 simultaneously, so that the combiner component and the dust cover 13 move simultaneously, the combiner component rises, the dust cover 13 is opened simultaneously, and the vehicle-mounted HUD is in a state shown in fig. 3. In the same manner as in the closing, the dust cover 13 is closed while the combiner unit is lowered, and the vehicle-mounted HUD assumes the state shown in fig. 4.
