1. A wearable projection device, comprising:
a main body, having a display portion and a support portion connected to each other;
an optical-mechanical module, disposed at the display portion, and including at least one light source;
a waveguide module, disposed at the display portion;
a first thermally conductive plate, connected to the at least one light source and extending from the display portion to the support portion;
a thermally conductive material, disposed between the optical-mechanical module and the first thermally conductive plate, wherein the optical-mechanical module, the thermally conductive material and the first thermally conductive plate are sequentially arranged along an arranging direction, wherein
an orthographic projection of the optical-mechanical module and an orthographic projection of the thermally conductive material along the arranging direction on the first thermally conductive plate are overlapped with the first thermally conductive plate at the display portion, and
the orthographic projection of the optical-mechanical module and the orthographic projection of the thermally conductive material along the arranging direction on the first thermally conductive plate are not overlapped with the first thermally conductive plate at the support portion; and
a control module, electrically connected to the optical-mechanical module, so that an image generated by the optical-mechanical module is displayed on the display portion by the waveguide module.
