Description

Mechanical structure capable of expanding laser navigation angle

Technical Field

The invention belongs to the technical field of laser, and particularly relates to a mechanical structure capable of expanding a laser navigation angle.

Background

The laser is an important component of the mobile robot and is also a leader of the walking route of the robot. The laser navigation system is a new navigation application technology developed along with the continuous maturity of a laser technology, and is suitable for operation navigation, field survey orientation and other works under the condition of poor sight. Each robot walking autonomously needs laser navigation, and some robots need more than one laser navigation, because the laser navigation requires more than 240 degrees of scanning angle, so like the laser on the sweeping robot is basically protruded out of the body, and because the sweeping robot is low in height, the design difficulty does not exist. However, if the laser is used in a small robot with a height of more than 1 m, the height of the laser should be about 20 cm from the ground, and the scanning angle is especially limited.

Disclosure of Invention

In view of the above problems, an object of the present invention is to provide a mechanical structure capable of extending the laser navigation angle, increasing the scanning angle range of the laser, without affecting the aesthetic appearance and the mechanical height of the upper body, and reducing the number of lasers used in the same machine.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a can expand laser navigation angle's mechanical structure, includes that laser keeps off lid, laser instrument and base, and wherein the laser instrument rotationally sets up on the base, laser keep off the lid set up in the top of laser instrument, and through a plurality of support columns along circumference distribution with the base is connected.

The laser is arranged at the position of the center of the base, which is deviated to the front.

The support column set up in the edge of laser stop cover, and be located the both sides and the rear side of laser instrument.

The supporting columns are inclined along the direction of the laser.

The width of each support post is within 8 degrees of the apex of the laser.

An upper body structure shell is arranged above the laser blocking cover.

The invention has the advantages and beneficial effects that:

the invention realizes the scanning angle range required by laser navigation by using the least laser for structural design, has simple and compact structure, saves space, improves the working efficiency of the mobile robot and has wider range of use scenes.

The invention uses the support of the minimum angle on the angle of laser scanning to enlarge the laser navigation scanning range

The invention can realize the scanning angle range required by laser navigation by only using one laser on the same machine.

The invention has beautiful appearance and does not influence the heightening structure upper body.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-2, the mechanical structure capable of extending a laser navigation angle provided by the present invention includes a laser blocking cover 1, a laser 2 and a base 3, wherein the laser 2 is rotatably disposed on the base 3, and the laser blocking cover 1 is disposed above the laser 2 and is connected to the base 3 through a plurality of support pillars 4 distributed along a circumferential direction.

The laser 2 is arranged at the position of the center of the base 3 deviated to the front, and the support columns 4 are arranged at the edge of the laser blocking cover 1 and are positioned at the two sides and the rear side of the laser 2.

As shown in fig. 4, each support post 4 is inclined in the direction of the laser 2, and the width of each support post 4 is within an angle of 8 ° with the laser 2 as the apex.

As shown in fig. 3, an upper body structure housing 5 is provided above the laser barrier cover 1.

The working principle of the invention is as follows:

as shown in fig. 4, the laser 2 can be placed at a point forward of the center of the whole robot, according to the range of the straight line light emitted by the laser, a laser blocking cover 2 can be designed, which has four supporting columns 4 as supports for the upper body structure, the design angle of the supporting columns 4 is 8 °, so that the emission range of the laser navigation generally requires more than 240 °, and the design can reach 360 ° -4x8 ° -328 °, so that the design requirement can be reached by using one laser, the scanning range of the laser is greatly increased, and the support of the four supporting columns 4 of 8 ° is enough to bear the weight of the upper body mechanical shell, and the whole height of the robot can not be limited.

In the design of the upper body structure shell 3, the appearance of any shape can be introduced, the base 3 can be in various appearance structure designs such as square shape and round shape, the overall shape of the robot can not be limited by the expansion design of the laser angle, and the attractiveness of the robot is improved.

Compared with other robots, some robots are provided with four lasers in the front and back directions and are respectively arranged at the positions of four corners of a square, although the design can meet the requirement of laser navigation, the occupied cost proportion of the lasers is larger, so that the design cost is greatly increased, and the overall arrangement of the robot is influenced in appearance. Therefore, the invention can increase the laser scanning angle to the maximum, can heighten the upper body of the robot to any height, saves the number of laser navigation used by the robot, saves the cost, and is very suitable for the structural design direction required by the current market.

The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, improvement, extension, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
