Description
Technical field
The utility model relates to a kind of driver train, particularly relates to a kind of read-out switching mechanism and HUD of vehicle-mounted HUD.
Background technology
Along with the develop rapidly in epoch, the raising of people's living standard, increasing severely with day of automobile pollution, automotive safety has become the problem that current customer is concerned about most.Automobile is being run at high speed, and particularly when running at high speed night, the display such as viewing instrument or viewing navigation if chaufeur is bowed, now front runs into emergency situation, just may cause traffic accident because having little time to take measures.According to an external survey, the road traffic accident of 45% is that pilot's line of vision is not enough, misoperation, cause vehicle and objects in front to collide causing, in order to reduce the traffic accident that this reason causes, according to the display system of military fighter aircraft, HUD (full name: HeadsUpDisplay, be called for short HUD) arise at the historic moment, it to drive the speed of a motor vehicle needed most, oil mass, navigation, driving safety such as to assist enter human eye at the important information projection, projected image is positioned in the suitable location in chaufeur front, thus make chaufeur remain the attitude of new line, avoid because of viewing instrument of bowing, navigating instrument or other driving ancillary equipments show information and the potential safety hazard caused, decrease the possibility causing traffic accident, also alleviate in observation objects car and the scene information of the outer Bu Tong distance of car and the eye strain that causes.
HUD is the flight additional gauge generally used at present on aircraft, is a kind of integrative electronic display equipment be made up of electronic building brick, display module, controller, high tension supply etc. occurred the sixties.It by information such as flight parameter, aiming attack, Autonomous test, with the form of image, character, can be projected on the optical, electrical read out instrument on the compound glass of passenger cabin dead ahead by optics.During aviator's scenery outer through compound glass observation tank, the information such as the character be superimposed upon on outdoor scene, image can be seen simultaneously.And project focal length and be positioned at imaging suite glass front, make aviator hardly with changing eyes focal length, can watch flight parameter at any time easily, visibility also can not be subject to sun-exposed impact.The purpose of HUD design allows aviator not need to bow the display and data of checking instrument, and remain the attitude of new line, Rapid Variable Design and eyes focal length needs of ignoring external environment between bowing and coming back constantly adjust the delay and discomfort that produce.Along with the develop rapidly of auto-industry, HUD is applied in automobile technical field gradually.
HUD in the market, its read-out is generally directly articulated on main body frame, and is driven by the switching mechanism be fixed on main body frame, thus overturns; When read-out is subject to external force (as artificial rotation, the road surface etc. of jolting), overturn because this read-out is direct driving by switching mechanism, external force suffered by read-out can directly be passed on the Transmission of switching mechanism, thus cause the damage of the gear of Transmission, severe patient can directly affect bursting apart of whole Transmission, thus affects the normal work of HUD.
Therefore, need one badly and drive effect and the better switching mechanism of protective effect.
Utility model content
The purpose of this utility model is that providing a kind of drives effect and the better read-out switching mechanism of protective effect.
Another object of the present utility model is to provide a kind of HUD, and this HUD has driving effect and the better read-out switching mechanism of protective effect.
For achieving the above object, the utility model provides a kind of read-out switching mechanism, overturn relative to main body frame for driving the read-out of HUD, wherein, described read-out switching mechanism comprises stationary rack, bracing frame and the motor be connected on support frame as described above and Transmission, support frame as described above to be connected on described main body frame in what rotate and to form center of turn, described stationary rack is arc structure and is connected on described main body frame, the center of circle of described stationary rack is positioned on described center of turn, described motor is connected with the input end of described Transmission, the mouth of described Transmission engages with described stationary rack, described read-out is connected on support frame as described above, whole read-out switching mechanism is driven with described center of turn for rotating in the center of circle by described motor, the rotation of described read-out switching mechanism drives described read-out rotate and realize upset.
Preferably, the both sides of support frame as described above are respectively equipped with rotating shaft, and described rotating shaft and described main body frame, in the connection of rotating, are formed centrally described center of turn in described rotating shaft, and support frame as described above is the connection of rotating by described rotating shaft and described main body frame.
Preferably, described Transmission comprises worm screw, transmission gear and axle drive shaft, the two ends of described axle drive shaft arrange driven wheel respectively, described transmission gear is connected with described axle drive shaft, described worm screw is connected with the output shaft of described motor and engages with described transmission gear, and described driven wheel engages with described stationary rack.
The HUD that the utility model provides, comprise main body frame, come back display main body and read-out, described new line display main body is arranged on described main body frame, described read-out is arranged in upset relative to described main body frame, also comprise read-out switching mechanism described above, described read-out is connected on the bracing frame of described read-out switching mechanism, and described read-out switching mechanism drives described read-out to overturn relative to described main body frame.
Compared with prior art, because the bracing frame of the utility model read-out switching mechanism is connected on main body frame in what rotate, and motor, Transmission and read-out are all connected on this bracing frame, stationary rack in arc structure is fixed on main body frame and with the mouth of Transmission and engages, therefore read-out switching mechanism is when driving read-out to overturn, whole read-out switching mechanism synchronously overturns together with read-out, actv. solves technical matters existing when switching mechanism fixing in prior art drives read-out to overturn, therefore the read-out that the carrying out of read-out switching mechanism of the present utility model drives is used, the harmful effect that external force produces it can better be resisted, there is good protective effect, and by engaging of stationary rack and Transmission, make to the switching process of HUD more steadily and stable, to drive effective, separately, the angle of read-out upset can be controlled by actv. by controlling this read-out switching mechanism, thus meeting the field range of the driver of different height.
