Shock absorbing adjustment device of deformable upright robot and deformable upright robot provided with shock absorbing adjustment device

Abstract

The invention relates to a shock absorbing adjustment device of a deformable upright robot. A left sliding rail piece and a right sliding rail piece are arranged at the lower end of a lifting part ina pair; sliding rails of the left sliding rail piece and the right sliding rail piece are in 'J' shapes; a damping spring sheet is arranged at the end point of a linear part; external expansion areasare arranged at the opposite sides of the two sliding rails; the bases of a left convex shaft and a right convex shaft of a seat stand are in boss shapes which are paired with the external expansion areas; in a nested state, the left convex shaft and the right convex shaft of the seat stand are in sliding fit with the sliding rails of the left sliding rail piece and the right sliding rail piece, and the ends of the left convex shaft and the right convex shaft protrude the outer sides of the left sliding rail piece and the right sliding rail piece; the external expansion areas of the left sliding rail piece and the right sliding rail piece are clamped at the bases of the left convex shaft and the right convex shaft in a corresponding way; the ends of the left convex shaft and the right convex shaft are clamped in clamping holes of a rear seat clamping plate, and the rear seat clamping plate is enabled to clamp the outer side faces of the left sliding rail piece and the right sliding rail piece; when the lifting part is vertically raised from the horizontal direction relative to the seat table, the left convex shaft and right convex shaft correspondingly slide to the end point of thelinear part from starting points of curved parts of the left and right sliding rails. By adopting the shock absorbing adjustment device, the excessive instantaneous offset amplitude of overall centers of gravity of a car head part and the lifting part can be reduced when a car body is deformed into the robot, so that a whole toy has phenomena of bounce and dumping.

Background technique [0002] The applicant’s first application number is 201520637206.5, which is called a Lycan sports car electric deformation robot toy, and the application number is 201620016106.5, which is a utility model patent named a deformation bus robot. The power output structure adopts a small DC The motor is used as the power source, and through the transmission mode of motor-input gear-transmission gear-output gear, it cooperates with the lever lifting structure of the car body to transmit the power. This kind of deformation robot toy lever lifting structure includes the following main structures: as the car body part The rear seat of the robot is used as the platform for the legs of the robot, as the lifting part of the waist and ...

AI Technical Summary

Problems solved by technology

[0003] In order to expose the seat as the leg of the robot, the lifting part of this type of deformed robot is a pair of vertical plates with inner and outer shafts. The fixed rear seat and seat platform are lifted from the horizontal to the vertical. After the applicant commercialized the technical content of the above two patents, it was found that when this type of toy transforms from the car body state to the human shape state, due to the fact that the head of the car is lowered To the high position, and the process of lifting the lifting part from horizontal to vertical, the force required to complete the deformation of the head and the lifting part changes gradually from large to small, and based on cost considerations, the actual small DC motor used is the speed Constant small motor, when the small motor transmits power to the input gear-transmission gear-output gear at a constant speed, it will eventually cause the head of the car to be prone to excessive output power in the second half of the deformation process due to excessive output power, and the front of the car during the deformation process. The instantaneous offset of the overall center of gravity of the upper part and the lifting part is too large, causing the whole toy to bounce or even fall over. This phenomenon occurs in the elongated car body, such as the deformation process from the car body state of the above-mentioned deformed bus robot to the human form state. especially evident in

[0004] The applicant tried to reduce the output power of the small motor to reduce the power output. When the power traction lever lifting structure is reduced, the instantaneous deviation of the center of gravity of the head and the lifting part can be reduced to a certain extent. The instantaneous offset of the overall center of gravity of the lifting part can reduce the occurrence of bouncing or even dumping during the upright deformation of the deformed bus robot; but at the same time, the scheme of reducing the output power slows down the state of the car body to a certain extent The deformation speed of the deformation to the humanoid state, and the output is too small, the first half of the lifting action of the head of the car is prone to the phenomenon that the output power is too small and the deformation process is too slow

[0005] In addition, after the applicant commercialized the technical content of the above two patents, he also found that the shaft and hole of the seat platform and the hole part of the rear seat splint were worn out due to the continuous relative rotation of the shaft and the hole during multiple deformations. , so that the inner and outer shafts, the seat, and the rear seat are hinged to each other to form a loose hinged structure, which makes it easier to sideways and topple during the deformation process
