Description

Dust cover type head display device

The present invention relates to a dust-proof head-up display device, in particular to a dust-proof head-up display device capable of preventing dust from entering the inside of the body, which uses three covers disposed above the opening of the base to fold and interlock the cover. The opening of the base is combined to prevent dust from falling into the interior of the base when dust is wiped, thereby achieving dustproofness and ensuring smooth operation.

The popular car head-up display device, also known as the Head Up Display, is designed to reduce the number and timing of the driver's line of sight leaving the road ahead, thereby improving the safety of driving.

In recent years, there have been many external head-up displays that can be added to the car. The functions of these head-up displays range from the simplest display speed and speed to the current water temperature, throttle position, fuel volume, overspeed warning, reversing image, battery voltage, and even speed radar. Some products also emphasize fast installation, as long as the computer is connected to the car, there is no need to install additional wiring; some car manufacturers' advanced models add navigation system and front and rear distance to the information displayed on the head-up display, which can be used for driving. The addition of a lot of convenience, and the price of commercially available external head-up display, from the simple function of hundreds of dollars, to the quality and versatility of the million.

As for the style and function of the external head-up display, related technologies can be considered in the TW I541542, CN 201410091114.1, CN 201410513879.X, CN 200780049317.2, CN 201320821555.3, TW M480074 and other patents. Most of these patents have dust-proof functions. However, in the current commercially available head-up display structure, the following problems generally exist, such as:

1. In order to reduce the cost, some head-up displays are directly used as a dust-proof cover by using the back plate of the reflective sheet, so that the reflective sheet has a protective barrier, and the cover is easily placed on the external force or the object is improperly placed. Causes damage and movement of the reflective sheet.

2. In some styles, the opening and closing of the anti-layer cover and the opening and closing of the reflective sheet are independently activated by different power sources. The operation between the two often has an uncoordinated situation, so the high failure rate makes the user deeply troubled. .

3. In the foregoing patents, some of them use a curtain-type cover as a means of protection against dust, but because of the long deployment or the winding stroke of the roller blind, the relative waiting time for the operation is also long, and It is necessary to have sufficient storage space, so the volume of the body is relatively large, and the outer shutter type head-up display, the opening and closing of the reflector is mostly independent operation, so it is easy to cause uncoordinated situations.

4. As far as the structure of the commercially available head-up display is concerned, the position of the cover body is mostly slightly lower than the opening of the body. Such a structure has a disadvantage that dust is easily dropped inside the body during wiping cleaning. After many years, the residual scale will affect the smoothness of the operation, resulting in the loss of the service life of the head-up display.

In order to solve the above problems, the creator of this case has finally completed the dust-proof head-up display device of this case after numerous research and improvement, that is, the purpose of the present case is to provide a kind of A dust-proof head-up display device capable of preventing dust from entering the inside of the body, and adopting three cover bodies disposed above the opening of the base to fold and interlock, thereby preventing dust from falling on the base when wiping dust Internally, it is effective in achieving dust prevention and ensuring smooth operation.
