The hand-held laser distance measuring device is an instrument for measuring distance by using laser. The hand-held laser ranging device has the advantages of light weight, small volume, simplicity in operation and the like, can be used in the fields of industrial measurement and control, mines, ports and the like, and can also be used in the building industry. When the hand-held laser ranging device works, a thin laser beam can be emitted to a target, the laser beam reflected by the target is received by the photoelectric element, and the time from emitting to receiving of the laser beam can be measured by the timer, so that the distance from a user to the target can be calculated. The handheld laser ranging device can also measure and calculate the area and the volume. The handheld laser ranging device can be used for indoor measurement, such as measurement of house area by a house management department. Also for example, the user takes measurements of the house to be finished, etc. The handheld laser ranging device can also be used for outdoor measurement, such as the measurement of the distance between buildings by a user.

The existing display screen and the existing protection screen (or touch screen) of the laser ranging device are respectively positioned on two sides of the shell, so that the display screen and the protection screen are not attached. After the laser ranging device is used for measurement, the measurement result can be displayed on the display screen, and when a user looks up the measurement result on the display screen through the protection screen (or the touch screen), the user also needs to visually penetrate through the distance between the display screen and the protection screen, so that the measurement data on the display screen has distance feeling and visual comfort is influenced. Therefore, there is a need for an upper cover and a housing for a laser distance measuring device to improve the visual comfort of the user when using the laser distance measuring device.

The upper cover and the housing for the laser ranging device according to one or more exemplary embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

Wherein the protective screen may be used to protect the display screen. In some embodiments, the display screen 220 and the protective screen 210 may be sequentially disposed on the housing 240. In some embodiments, the type of display 220 may include a liquid crystal display, from a type perspective. As an example, the housing 240 may include at least one recess for receiving the display screen 220. As shown in fig. 2, the at least one groove may include a first groove 241, and when the display screen 220 is placed in the first groove 241, the protection screen 210 is placed on the housing 240 so that the display screen 220 can be attached to the protection screen 210. In some embodiments, the protective screen 210 may be positioned on the display screen 220 such that the protective screen 210 may be attached to the display screen 220 at a zero distance, i.e., the upper surface of the display screen 220 may be attached to the lower surface of the protective screen 210. This can improve the comfort level of the user using the laser ranging device 100 in one or more embodiments of the present disclosure, and the user does not feel the distance of the measured data on the display screen 220 due to the space between the display screen 220 and the protection screen 210, which may affect the visual comfort level of the user.

In some embodiments, the cover assembly 200 may further include a key 260 and a key circuit board 250. In some embodiments, the at least one groove may further include a second groove 242, and the second groove 242 may be located on the housing 240. In some embodiments, the second groove 242 may be used to place the key 260 and the key circuit board 250, and the key 260 may correspond to the key circuit board 250.

In some embodiments, the protective screen 210 may not only completely cover the display screen 220, but the protective screen 210 may also partially cover the keys 260.

In some embodiments, the perimeters of the first protective screen 211 and the second protective screen 212 may each be silk-screened with various patterns and/or text.

In some embodiments, the protective screen 210 may include at least one cutout. As shown in fig. 2, as an example, the second protection screen 212 may include at least one hollowed-out portion. For example, the second protection screen 212 may include two hollows 213. In some embodiments, the key 260 passes through the protection screen 210 through the hollow 213. As an example, the key 260 may include a key part 261 and a key sheet 262. The key part 261 may pass through the second protection screen 212 through the hollowed-out part 213. The non-hollowed-out portion of the second protection screen 212 may be attached to the key sheet 262.
