Embodiment

Refering to Fig. 1 and Fig. 2, the head-up display in the utility model embodiment includes the housing 1, (main frame of host component 2 Component 2 includes control board), projecting subassembly 3 and imaging screen 4 be (it is appreciated that the project content of projecting subassembly 3 is projected Onto the imaging screen 4.And the imaging screen 4 can be independently arranged, or when the head-up display is installed on vehicle, by vehicle Front windshield substitute, i.e., according to the difference of application environment, the head-up display can be independently arranged the imaging screen 4 or without this into As screen 4), wherein housing 1 includes lower house 11 and upper shell 12, and lower house 11 and upper shell 12 form receiving space；Host groups Part 2 is located in receiving space；Projecting subassembly 3 is fixed in housing 1, and (projecting subassembly 3 is fixed in the up or down housing of upper shell 12 On 11) on, and projecting subassembly 3 and imaging screen 4 respectively positioned at host component 2 it is rear before (refer to before in the utility model along throw The projecting direction of shadow component 3, after refer to along the reverse of the projecting direction of projecting subassembly 3) both sides are (certainly in other variant embodiments In, imaging screen 4 when setting can also it is mobile to projecting subassembly direction so that the imaging screen 4 is not located at host component 2 before Side), the lower end of projecting subassembly 3 be in contact with lower house 11 on so that projecting subassembly 3 to be sunk, i.e. middle setting compared with the prior art Projecting subassembly 3 above heat abstractor, the height of the projecting subassembly 3 in the utility model embodiment by relative reduction, Can solve the problems, such as that the projecting subassembly 3 that the sight of part driver is located above heat abstractor blocks to a certain extent.

After the sinking of projecting subassembly 3, the part light path of projecting subassembly 3 may be caused to be blocked by housing 1, can not effectively be passed It is delivered on imaging screen 4, in the utility model preferred embodiment, projecting subassembly 3 is obliquely installed so as to project with respect to lower house 11 The project content of component 3 can effectively project to imaging screen 4.

In a particular embodiment, projecting subassembly 3 is A with respect to the angle that lower house 11 is obliquely installed, wherein 105 ° >=A >= 97 °, such as A=97 °, 100 °, 103 ° or 105 °.

After projecting subassembly 3 is obliquely installed with respect to lower house 11, the part light path of projecting subassembly 3 can tilt (phase accordingly For projecting subassembly 3 and lower house 11 are without the horizontal optical path being obliquely installed), the part light path quilt of projecting subassembly 3 may be caused Housing 1 blocks, and can not effectively be delivered on imaging screen 4, in the utility model particularly preferred embodiment, upper shell 12 from The projection original position A of projecting subassembly 3 starts, is at least partly arranged to avoid projection group along the projecting direction of projecting subassembly 3 The shape of the light path of part 3 is so that the project content of projecting subassembly 3 can effectively project to imaging screen 4.Upper shell 12 avoids projecting subassembly 3 The shape of light path can be arc (as schemed) or wedge shape.

In a particular embodiment, projecting subassembly 3 is TFT projecting subassemblies 3, the low cost of TFT projecting subassemblies 3, high temperature resistant and aobvious Show that effect can be widely used well.

TFT projecting subassemblies 3 include projection screen, and the length-width ratio of the projection screen is K, wherein K >=2, by larger Length-width ratio reduces the height of projecting subassembly 3 from another point of view, i.e., in driver's angular field of view as far as possible in the lateral direction It has been shown that, rather than short transverse.

The head-up display also includes the heat abstractor 5 being located in the receiving space, is directly arranged in by projecting subassembly 3 After on lower house 11, by heat abstractor 5 to lateral arrangement not increase the height of the head-up display other parts, it will radiate Device 5 is arranged in the side (left side or right side of host component 2) vertical with projecting subassembly 3 of host component 2, wherein radiating dress Putting 5 includes heat-conducting piece 51 and radiating subassembly 52, and heat-conducting piece 51 guides the heat of projecting subassembly 3 to radiating subassembly 52 with described Radiating subassembly 52 distributes.The present embodiment can effectively give projection group in the case where not increasing the height of the head-up display Part 3 radiates.

In a particular embodiment, heat-conducting piece 51 be heat conducting pipe (heat conducting pipe can be the heat-conducting piece for having in pipe phase-change material, Can also be the good tubulose heat-conducting piece of heat conduction), radiating subassembly 52 includes fin 521 and fan 522, one end of heat conducting pipe with Fin 521 is connected, and close to projecting subassembly 3, the heat that fan 522 is directed onto fin 521 is blown out the other end.

In a preferred embodiment, heat-conducting piece 51 is copper part, and metal copper material has good processability, uses plastic deformation Deformation method can be bent into preset shape according to the position of radiating subassembly 52 and projecting subassembly 3, be processed good rear and can protect Hold the shape.

Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is all It is the equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or directly or indirectly uses In other related technical areas, similarly it is included in scope of patent protection of the present utility model.
