Abstract
A kind of Vehicular navigation system, comprising: which windshield glass, is covered in the liquid crystal film on the windshield glass surface, and the navigator configured with projecting subassembly, the camera lens of the projecting subassembly is used for navigation screen Projection Display towards the liquid crystal film in the liquid crystal film；The system further comprises state switch, and the state switch connects with the current supply circuit of the liquid crystal film, is powered by controlling the liquid crystal film or power-off switches the liquid crystal film and is translucent state or pellucidity.This navigation system can be convenient the state of ground switchable liquid crystal film, the state that is only translucent if necessary reflects navigation screen to driver, and other time transparent state facilitates driver to observe front road conditions due to being configured with state switch.
Description
Technical field
The utility model relates to the vehicles that Vehicular navigation system more particularly to a kind of navigation screen are projected in windshield glass
Navigation system.
Background technique
Traditional Vehicular navigation system is mainly by two kinds, and one is the navigation system of vehicle itself, another kind is to be supported on
The self-contained navigation system of console, such as mobile phone, dedicated omniselector.Common defects existing for these navigation system are: driving a vehicle
In the process, driver need to bow and watch navigation screen, and there are security risks, especially in high speed traveling.
Have thus human hair be illustrated can navigation screen be projected in the Vehicular navigation system of windshield glass.Such navigation system
System includes: windshield glass, is covered in the liquid crystal film on the windshield glass surface, and the navigation configured with projecting subassembly
Instrument, the camera lens of the projecting subassembly towards the liquid crystal film, for by navigation screen Projection Display windshield glass institute
Liquid crystal film is stated, driver does not need to bow, and head-up may be viewed by navigation screen, can effectively overcome to bow and see that navigation screen exists
Security risk.But there are still following technological deficiencies for this Vehicular navigation system: projection to the navigation screen on liquid crystal film
Visibility it is directly related with the light transmittance of liquid crystal film, if light transmittance is higher, projection to navigation screen thereon can
Opinion property is poor, when especially sunlight is stronger；And if light transmittance is lower, the sight of driver can be blocked, influences to drive safely
It sails, when especially liquid crystal film occupies windshield glass larger area.
Utility model content
The purpose of the utility model is to provide a kind of Vehicular navigation systems, to solve on existing for existing Vehicular navigation system
State technological deficiency.
In fact, the time for needing to watch navigation screen in driving is seldom, only need to watch at the crossing etc. of road conditions complexity
Navigation screen.Based on this, the technical solution adopted in the utility model is as follows:
A kind of Vehicular navigation system comprising:
Windshield glass；
It is covered in the liquid crystal film on the windshield glass surface；And
Navigator, the navigator are configured with projecting subassembly, and the camera lens of the projecting subassembly is used towards the liquid crystal film
In by navigation screen Projection Display in the liquid crystal film；
It further include state switch, the state switch connects with the current supply circuit of the liquid crystal film, passes through
Control that the liquid crystal film is powered or power-off switches the liquid crystal film and is translucent state or pellucidity.
Preferably, the state switch is installed on the steering wheel of vehicle.
Preferably, the navigator is installed on the top in compartment.
Preferably, the navigator is installed at console.
Preferably, the navigator is configured with voice broadcast module.
Compared with prior art, the utility model at least has the advantages that
This navigation system can be convenient the state of ground switchable liquid crystal film due to being configured with state switch, only must
The state that is translucent when wanting reflects navigation screen to driver, and other time transparent state facilitates driver to observe front road
Condition.
Since liquid crystal film is only just translucent state if necessary, remaining most of the time transparent state, because
This can by its translucent light transmittance be arranged it is lower so that the visibility of navigation screen is preferable.
Detailed description of the invention
Fig. 1 is the Vehicular navigation system of first embodiment；
Fig. 2 is the Vehicular navigation system of second embodiment.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples.
Description of symbols:
10---- windshield glass 20---- liquid crystal film
30---- is configured with the navigator 40---- driver seat of projecting subassembly
The steering wheel of 50---- state switch 60---- vehicle.
Referring to Fig.1, first embodiment Vehicular navigation system includes: windshield glass 10, is covered in the windshield glass
The liquid crystal film 20 on 10 surfaces, navigator 30 and state switch 50 configured with projecting subassembly.
The transparent state when power is off of liquid crystal film 20, be translucent state after energization.
Navigator 30 is installed on the top in compartment, and the camera lens of the projecting subassembly of navigator 30 is towards the liquid crystal film
20, it is used for navigation screen Projection Display in the liquid crystal film 20.
The state switch 50 is installed on the steering wheel 60 of vehicle, the state switch 50 and the liquid crystal
The current supply circuit of film 20 connects, and switches the liquid crystal film 20 in semi-transparent by controlling the liquid crystal film 20 and being powered or power off
Bright state or pellucidity.
In driving, when driver needs to watch navigation screen, institute is controlled by the state switch 50 on steering wheel 60
The energization of liquid crystal film 20 is stated, so that liquid crystal film 20 is become translucent, the navigation screen that navigator 30 projects is reflected to and is driven
The eyes for the person of sailing.When not needing viewing navigation screen, it is thin that the liquid crystal is controlled by the state switch 50 on steering wheel 60
Film 20 powers off, and so that liquid crystal film 20 is become pellucidity, liquid crystal film 20 will not block pilot's line of vision, and driver is convenient to
Observation front road conditions.
Navigator 30 preferably also configures voice broadcast module, with voice broadcast navigation information in real time.
Referring to Fig. 2, second embodiment Vehicular navigation system includes: windshield glass 10, is covered in the windshield glass
The liquid crystal film 20 on 10 surfaces, navigator 30 and state switch 50 configured with projecting subassembly.
The transparent state when power is off of liquid crystal film 20, be translucent state after energization.
Navigator 30 is installed at console, and the camera lens of the projecting subassembly of navigator 30 is used towards the liquid crystal film 20
In by navigation screen Projection Display in the liquid crystal film 20.
The state switch 50 is installed on the steering wheel 60 of vehicle, the state switch 50 and the liquid crystal
The current supply circuit of film 20 connects, and switches the liquid crystal film 20 in semi-transparent by controlling the liquid crystal film 20 and being powered or power off
Bright state or pellucidity.In addition, state switch 50 can also be installed on other places convenient for driver's operation.
