[0034] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0035] like Figure 1-2As shown, a head-up display 100 provided in one embodiment of the present application includes a shell body 1 and an image generating unit, and the image generating unit is installed in the shell body 1. The shell body 1 is provided with a receiving cavity 11, and the image generating unit includes a backlight module 2, a display screen 3 and a heat sink 4. The backlight module 2 and the display screen 3 are received in the receiving cavity 11, and the backlight module 2 and the display screen 3 are both located between the shell body 1 and the heat sink 4. The heat sink 4 is detachably connected to the shell body 1 and covers the receiving cavity 11. The heat sink 4 and the shell body 1 jointly clamp the backlight module 2 and the display screen 3, so that the backlight module 2 and the display screen 3 can be relatively fixed relative to the shell body 1. In other words, the heat sink 4 can serve as a part of the shell to protect the internal parts of the head-up display 100. Compared with the method in which the image generating unit of the head-up display 100 is provided with an optical cavity component, the optical cavity component can be eliminated, which is conducive to simplifying the assembly process and improving the assembly efficiency of the head-up display 100.

[0036] It is understandable that there are many ways to detachably connect the shell body 1 and the radiator 4, which can be achieved by setting threads and matching screws, or by setting convex or buckle methods, or by setting mutual magnetic attraction methods. The specific method can be selected according to needs and is not limited here. In this embodiment, the shell body 1 and the radiator 4 are connected by threads and matching screws. Specifically, Figure 4 As shown, threaded columns 15 with internal threads are arranged around the shell body 1, and the radiator 4 is provided with avoidance holes 43 in the area just above the threaded columns 15.
