Abstract: A hard disk bracket configured to be installed on a case includes a tray, a base, a handle, a pin, and a latch. The tray has an accommodating space. The base is connected to the tray. The handle is disposed in the base and has a first slide part detachably fastened with the base. The pin is disposed through the handle and the base. The latch is disposed in the base and is detachably fastened with the case. The latch is fastened with the handle and has a second slide part penetrating the handle for extending outside the base.

Abstract: An optical module includes a micro spectrometer. The micro spectrometer includes an optical crystal, a lens, and a photosensitive assembly. The optical crystal is configured to receive detection light and covert the detection light into interference light. The optical crystal is surrounded by a sleeve, the sleeve configured to fix a position of the optical crystal. The lens is configured for receiving the interference light and focusing the interference light. The photosensitive assembly is configured for imaging the interference light into an interference image. The optical module further comprises a controller. The controller is electrically connected to the photosensitive assembly, and the controller is used to convert the interference image into light wavelength signals and light intensity signals.

Abstract: A storage compartment cover for a vehicle, the storage compartment cover including a housing that supports a winding shaft on an inside of the housing so that the winding shaft is rotatable about a winding shaft axis; a cover web that is supported on the winding shaft and pullable from the winding shaft; two axial housing ends that are respectively covered by respective end caps, wherein at least one movable end cap of the respective end caps is supported moveable between an axially outer engagement position and an axially inner disengagement position; a spring element that supports the at least one movable end cap in the engagement position and imparts a spring reset force upon the at least one movable end cap when the at least one movable end cap is moved into the disengagement position.
