Description

Robot chassis collision avoidance structure

Technical Field

The utility model belongs to the technical field of the robot and specifically relates to a collision avoidance structure of robot chassis.

Background

With the development of science and technology, mobile robots have been increasingly used in production and life. The robot is to avoid collision as much as possible in the moving process, on one hand, the robot generates collision, so that a sensor or software in the robot is in a problem, the robot is out of control, on the other hand, a shell of the robot is greatly damaged when colliding against a wall or an obstacle, and if the shell of the robot collides against a person, the person is in danger. However, with the development of mobile robots, the moving paths and environments of the robots are more diverse, how to avoid collision of the robots is a key problem to be considered in design, and from the cost perspective, the collision avoidance structure of the robots cannot be too complex, which may lead to the increase of the production cost of the robots.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a collision structure is kept away to robot chassis utilizes to keep away and bumps the shell and trigger to keep away and bump the sensor and realize the robot scram action, effectively improves the robot and removes the security performance.

The purpose of the utility model is realized through the following technical scheme:

the utility model provides a collision structure is kept away to robot chassis, includes keeps away to bump shell, shell fragment and keeps away and bumps the sensor, keeps away movably robot drain pan one side of locating of bumping the shell, just keep away and be equipped with the shell fragment between shell and the robot drain pan, it is equipped with and keeps away the strip to keep away to bump shell front side, the robot drain pan is close to and keeps away and bumps shell one side and be equipped with and keep away and bump the sensor.

The collision avoiding shell is provided with a hook, the bottom shell of the robot is provided with a notch, and the hook is hooked with the corresponding notch.

And a plurality of collision avoidance sensors are uniformly distributed on one side, close to the collision avoidance shell, of the bottom shell of the robot.

The utility model discloses an advantage does with positive effect:

1. the utility model discloses utilize to keep away and bump the shell and trigger and keep away and bump the sensor and realize the scram action of robot, effectively improve the robot and remove the security performance.

2. The utility model discloses set up the shell fragment and realize keeping away and bump shell extrusion and resilience, simple structure is reliable avoiding bumping between shell and the robot drain pan.

3. The utility model discloses be equipped with the strip of bumping of keeping away that rubber made on keeping away and bump the shell and play the cushioning effect.

Drawings

Figure 1 is a schematic structural diagram of the present invention,

figure 2 is a schematic view of the structure of the dodging housing in figure 1,

figure 3 is a schematic structural view of the bottom shell of the robot in figure 1,

fig. 4 is a schematic view of the usage state of the present invention.

Wherein, 1 is for avoiding bumping the shell, 2 is for avoiding bumping the strip, 3 is the robot drain pan, 4 is for avoiding bumping the sensor, 5 is the shell fragment, 6 is the couple, 7 is the notch.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1-4, the utility model discloses a dodge shell 1, shell fragment 5 and keep away and bump sensor 4, keep away and be equipped with couple 6 on the shell 1, be equipped with notch 7 on the robot drain pan 3, it passes through to keep away shell 1 couple 6 articulates and realizes being connected with robot drain pan 3 on corresponding notch 7, then installs the chassis epitheca on robot drain pan 3 again, makes and keeps away and bump shell 1 and can not fall out, couple 6 has certain length, can make like this and avoid shell 1 to have certain moving range keep away and bump strip 2 that shell 1 front side was equipped with rubber and made keep away be equipped with shell fragment 5 between shell 1 and the robot drain pan 3, just shell fragment 5 all locates on the robot drain pan 3 with keeping away and bump sensor 4.

The utility model discloses a theory of operation does:

when the robot advances and meets the obstacle, the obstacle collides with the collision avoidance strip 2 on the collision avoidance shell 1, and the extrusion makes the collision avoidance shell 1 move integrally to the center of the robot bottom shell 3, so that the collision avoidance shell 1 collides with the collision avoidance sensor 4 to trigger and send a signal to the robot system, so that the robot stops advancing immediately, thereby playing a role in scram, and after triggering and stopping the movement, the collision avoidance shell 1 is in the initial position can be rebounded under the action of the elastic sheet 5, and the collision avoidance strip 2 can effectively protect the robot from collision damage and can protect personal safety. In the embodiment, four collision avoidance sensors 4 are uniformly distributed on one side of the robot bottom shell 3 close to the collision avoidance shell 1, and the collision avoidance sensors 4 are known in the art and are commercially available products.
