Problems solved by technology

Such a process is time consuming and the accuracy of the product may vary due to the manual assembly process, gluing process, etc.
Third, the functionality of the bubble vials is limited because each bubble vial can only recognize one level relative to the vertical axis instead of two or more

Abstract

A laser level (21) contains a housing (20), an electronic tilt sensor (32) located in the housing (20); a controller (30) to which the electronic tilt sensor (32) is connected, and a laser module (36). The controller (30) is communicable with a first display device (24) and a second display device (26). The laser module (36) is adapted to project a straight ground laser line on a flat surface. The electronic tilt sensor (32) is adapted to detect a tilt of the laser level and provide a measurement signal to the controller (30). The controller (30) is adapted to provide a display signal to the first and second display devices (24, 26) to display the information about the tilt. By using the electronic tilt sensor (32), the laser level (21) can provide the accurate indicate of the tilt of the device and also allows such tilt information to be processed further.

Description

technical field [0001] This invention relates to portable electronic instruments, and more particularly to laser-based levels. Background technique [0002] Laser line products are commonly used on construction sites and project at least one clearly visible straight laser line to provide a reference line for the user. Traditionally, bubble vials are often used in laser levels to provide a visual reference for the user, so that when the laser level is pointing upwards, it can be determined whether the laser level (and thus the laser line emitted by it) is aligned with a vertical line perpendicular to the ground. The straight axis deviates from each other. [0003] However, a number of problems arise when bubble vials are used in laser levels. For example, an air bubble in a vial is not easy to check, and whether it is level can only be judged by the human eye, which is not accurate. Additionally, during the manufacturing process of the laser level, the laser line must be a...
