Description

Technical Field

[0001] The utility model relates to the technical field of laser sensors, in particular to a 3D laser sensor for a humanoid robot. Background Art

[0002] Laser sensor: A sensor that uses laser technology for measurement. It consists of a laser, a laser detector, and a measurement circuit. Laser sensors are a new type of measuring instrument. Their advantages include contactless, long-distance measurement, high speed, high accuracy, a large measuring range, and strong resistance to light and electrical interference. A robot is an intelligent machine capable of semi-autonomous or fully autonomous operation. Robots can perform tasks such as operations or movement through programming and automatic control. To improve their mobility, 3D laser sensors are often installed on robots.

[0003] However, existing 3D laser sensors are generally fixed to the housing during installation. After long-term use, the 3D laser sensor will be damaged and need to be replaced. However, since the 3D laser sensor is fixed to the housing, the 3D laser sensor needs to be replaced together with the housing, which makes the replacement more troublesome and causes a waste of resources. For this reason, we propose a 3D laser sensor for humanoid robots. Utility Model Content

[0004] The purpose of the utility model is to provide a 3D laser sensor for a humanoid robot.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a humanoid robot 3D laser sensor, comprising a shell, a fixed plate fixedly connected to the surface of the shell, a rotatable upper cover connected to the top of the shell, a groove provided on the surface of the fixed plate, the fixed plate being connected to the shell through the groove, a D laser sensor being provided in the groove between the shell and the fixed plate, a support rod fixedly connected to the inner wall of the shell, a circuit board being mounted on the support rod by bolts, and two fixing rods fixedly connected to the back side of the fixing plate, the two fixing rods being respectively located on both sides of the D laser sensor, an extrusion plate being sleeved on the two fixing rods, a non-slip pad being provided at the bottom of the extrusion plate, and a handle being fixedly connected to the top of the extrusion plate.

[0006] As a further solution of the present invention: a spring is sleeved on the circumferential surface of the fixing rod, the top of the fixing rod is fixedly connected to the limiting plate, one end of the spring is fixedly connected to the bottom of the limiting plate, and the other end of the spring is fixedly connected to the top of the extrusion plate.

[0007] As a further solution of the present invention: a through hole is provided on the top of the extrusion plate, and the extrusion plate is slidably sleeved on the fixing rod through the through hole.

[0008] As a further solution of the present invention: a ring plate is fixedly sleeved on the circumferential surface of the D laser sensor, and the diameter of the ring plate is larger than the diameter of the groove.

[0009] As a further solution of the present invention: the number of the support rods is four, and the four support rods are respectively located at the four corners of the bottom of the circuit board.

[0010] As a further solution of the present invention: the number of the D laser sensors is two, and the two D laser sensors are respectively located on both sides of the shell surface.

[0011] By adopting the above technical solution, compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model opens the upper cover by rotating and then pulling the handle toward the rear side. The handle will drive the extrusion plate to slide toward the rear side, and the extrusion plate will squeeze the spring to separate the extrusion plate from the 3D laser sensor. Then the 3D laser sensor can be removed from the groove, and a new 3D laser sensor can be installed in the groove. Then the handle is released and the spring will rebound the extrusion plate, and the extrusion plate will slide toward the direction of the 3D laser sensor. The extrusion plate will squeeze and limit the 3D laser sensor. The anti-slip pad on the extrusion plate can improve the stability between the extrusion plate and the 3D laser sensor, thereby stopping the extrusion plate and the 3D laser sensor from sliding, making it easy to disassemble the 3D laser sensor, thereby facilitating the replacement of the 3D laser sensor and reducing resource waste.

[0013] Other advantages, objectives and features of the present invention will be described in part in the following description and will be apparent to those skilled in the art based on an examination of the following or may be learned from the practice of the present invention.
