Embodiment Construction
[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0033] like Figure 1-5 As shown, the retractable obstacle-crossing arm controlled by the linear motor includes a front traveling wheel 7-1 and a rear traveling wheel 7-2;
[0034] The front travel wheel 7-1 is installed on the telescopic support arm 8, and the rear travel wheel 7-2 is installed on the support arm body 2; the rear travel wheel 7-2 is provided with a power output shaft 1, which drives the The rear travel wheel 7-2 rotates, and the rear travel wheel 7-2 drives the front travel wheel 7- 1 turn;
[0035] The telescopic support arm 8 can perform telescopic motion relative to the support arm body 2 under the driving of the linear motor cam combination 6; the tensioner mechanism 5 fixed on the support arm body 2 cooperates with the cam of the linear motor cam combination 6 to Tighten the obstacle crossing track 9.

The invention discloses a linear motor controlled retractable obstacle-crossing support arm, comprising a front road wheel and a rear road wheel. The front road wheel is mounted on a retractable support arm part, and the rear road wheel is mounted on a support arm body; the rear road wheel is provided internally with a PTO (power take-off) shaft for driving the rear road wheel to rotate, and the rear road wheel drives the front road wheel to rotate by an obstacle-crossing track; driving by a cam mechanism of a linear motor, the retractable support arm part can perform concertina movement relative to the support arm body; and a tensioner mechanism fixed on the support arm body is matched with a cam of the cam mechanism of the linear motor to tension the obstacle-crossing track. According to the linear motor controlled retractable obstacle-crossing support arm and an obstacle-crossing robot, the linear motor is small in size, light in weight, large in thrust, and high in transmission accuracy; the cam mechanism and the tensioner mechanism are simple in structure, convenient to manufacture, and safe and reliable; the support arm part is capable of stretching and changing length, thus the adaptability to complex environments is excellent; by changing the retractable support arm part different in length and the tensioner different in size, the object of adjusting the overall length of the support arm is easily achieved.
Description
technical field [0001] The invention relates to the technical field of advanced manufacturing and automation, in particular to a telescopic obstacle-surmounting arm and an obstacle-surmounting robot controlled by a linear motor. Background technique [0002] As more and more robots work in complex environments in the wild, how to improve their adaptability to complex environments has become an important indicator to measure robot performance. At present, most of the obstacle-surmounting robots on the market use obstacle-surmounting crawlers on the arms, and climb over obstacles through the crawlers, which have the following disadvantages: [0003] 1. The obstacle crossing height is determined by the length of the robot arm; [0004] 2. The length of the arm of this type of robot is affected by the overall size and weight of the robot, and it often cannot be very long; [0005] 3. The length of the arm is fixed, and the flexibility and maneuverability are poor. SUMMARY OF...
