Description

Technical Field

[0001] The utility model relates to the technical field of robots, in particular to a robot based on laser ranging. Background Art

[0002] A robot is an intelligent machine that can work semi-autonomously or fully autonomously. It can perform tasks such as operation or movement through programming and automatic control. It has basic characteristics such as perception, decision-making, and execution. It can assist or even replace humans to complete dangerous, heavy, and complex tasks, improve work efficiency and quality, serve human life, and expand or extend the scope of human activities and capabilities.

[0003] Patent No. 201821588299.7 discloses a robot based on laser ranging. The device has a very wide range of applications, is simple and reliable to control, and the cost can be controlled very low.

[0004] However, when the existing robot based on laser ranging is used, the laser ranging module is installed on the surface of the robot. The robot will inevitably be hit during movement. When the robot is hit, the impact force generated by the collision will be transmitted to the laser ranging module, which will have a certain impact on the service life of the laser ranging module. Therefore, a robot based on laser ranging is set up. Utility Model Content

[0005] The main purpose of the utility model is to provide a robot based on laser ranging. The utility model solves the problem that it is inconvenient to protect the laser ranging sensor on the robot body when the existing robot based on laser ranging is in use by arranging a buffer plate, a slide groove, a slide plate, a damping rod, a damping spring A, a damping spring B, a ring plate and a connecting frame.

[0006] The technical solution adopted by the utility model to solve the technical problem is a robot based on laser ranging, comprising a robot body and a fixing frame, a laser ranging sensor for ranging is fixed by screws on the surface of the robot body, a connecting frame for protecting the laser ranging sensor is fixed by screws on the outside of the robot body, a damping rod connected to the connecting frame is fixed by screws inside the connecting frame, a sliding groove for sliding a slide plate is provided on the inside of the connecting frame, a damping spring A for buffering is welded on one side of the slide plate, a buffer plate connected to a damping spring B is fixed by screws on the outside of the slide plate, a ring plate connected to a rubber block is welded on the outside of the damping spring B, and a display screen for displaying the ranging result is fixed by screws on one side of the robot body.

[0007] By adopting the above technical solution, when the robot body performs laser ranging, the laser ranging sensor outside the robot body aims at the target through the internal laser diode to emit laser pulses. After being reflected by the target, the laser is scattered in all directions, and part of the scattered light returns to the sensor receiver. The time from the light pulse being emitted to the return being received is recorded and processed, and the target distance can be measured and displayed on the display screen.

[0008] When a foreign object touches the robot body, the foreign object first contacts the rubber block outside the ring plate, and then the ring plate presses the damping spring B in the buffer plate, and then the damping spring B is compressed to buffer the impact force generated by the collision, and then the slide plate outside the buffer plate slides in the slide groove opened in the connecting frame, and then the buffer plate presses the damping spring A in the connecting frame, and then the damping spring A is compressed, and at the same time the damping rod inside the connecting frame contracts, further buffering the impact force generated by the collision, thereby facilitating the protection of the laser ranging sensor outside the robot body.

[0009] Specifically, a motor driving a threaded rod to rotate is screwed inside the fixing frame, a driving sleeve driving a driving plate to move is threadedly connected outside the threaded rod, and a fixing cover protecting the display screen is welded outside the driving plate.

[0010] By adopting the above technical solution, when the laser ranging is completed, the motor in the fixed frame converts the received electrical energy into mechanical energy, the motor drives the threaded rod to rotate, and then the driving sleeve outside the threaded rod drives the fixed cover to move, and then the fixed cover moves to the outside of the display screen, thereby facilitating the protection of the display screen.

[0011] Specifically, a connecting sleeve is welded on one side of the fixing cover and slides outside the vertical rod fixed by screws on the outer side of the robot body.

[0012] By adopting the above technical solution, when the fixed cover moves, the connecting sleeve outside the fixed cover slides outside the vertical rod, thereby improving the stability of the movement of the fixed cover.

[0013] Specifically, a through hole is provided on the surface of the buffer plate for the laser ranging sensor to measure the distance.

[0014] By adopting the above technical solution, when the laser ranging sensor outside the robot body is working, the laser ranging sensor performs laser ranging through the through hole opened on the surface of the buffer plate.

[0015] Specifically, the input ends of the motor and the laser ranging sensor are electrically connected to the output end of the battery inside the robot body.

[0016] By adopting the above technical solution and connecting to an external power source, the electrical device can work normally.

[0017] Beneficial effects of the utility model:

[0018] (1) The utility model discloses a robot based on laser ranging. When a foreign object touches the robot body, the foreign object first contacts the rubber block outside the ring plate, and then the ring plate presses the damping spring B inside the buffer plate, and then the damping spring B is compressed to buffer the impact force generated by the collision. Then the slide plate outside the buffer plate slides in the slide groove provided in the connecting frame, and then the buffer plate presses the damping spring A inside the connecting frame, and then the damping spring A is compressed. At the same time, the damping rod inside the connecting frame contracts to further buffer the impact force generated by the collision, thereby facilitating the protection of the laser ranging sensor outside the robot body.

[0019] (2) The utility model describes a robot based on laser ranging. When the laser ranging is completed, the motor in the fixed frame converts the received electrical energy into mechanical energy, and the motor drives the threaded rod to rotate. Then the driving sleeve outside the threaded rod drives the fixed cover to move, and then the fixed cover moves to the outside of the display screen, thereby facilitating the protection of the display screen.
