DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1-3As shown, it includes a supporting mechanism 1, a power mechanism 2, a walking mechanism 3, and a power supply 4. The supporting mechanism includes a side plate 11, a panel 12 and a back plate 13. The side plate 11 is two rectangular plates with a plurality of slots and through holes, which are arranged opposite to each other on the left and right sides, and each of the side plates 11 is connected to a supporting shaft 111 on the outward side. The panel 12 and the back plate 13 are arranged opposite to each other front and back and form a cavity together with the left and right side plates 11, and the power mechanism 2 is installed in the cavity; the power mechanism 2 is a motor 21, and the bottom of the motor 21 extends out of the cavity and there is a rotating shaft 211 on each of the left and right sides, and each of the rotating shafts 211 is fixedly connected to an eccentric wheel 212; the walking mechanism 3 includes two Y-shaped plates 31, the V portion of the Y-shaped plate 31 is downward, the connection between the V portion and the I portion is installed on the eccentric wheel 212, and the top of the I portion away from the V portion is installed on the supporting shaft 111.

[0018] like Figure 1 As shown, each eccentric wheel 212 is provided with a crank 213 near the circumference, and the cranks 213 of the left and right eccentric wheels 212 are installed at an angle of 180°, so that the Y-shaped plates 31 of the walking mechanism 3 move in a staggered manner.

[0019] like Figure 1 As shown, a slide groove 311 is provided at the top end of the Y-shaped plate 31I, and the support shaft 111 slides up and down in the slide groove 311, so that the Y-shaped plate 31 of the walking mechanism 3 moves up and down.

[0020] like Figure 1 As shown, a small hole is opened at the top of the Y-shaped plate 31I, and a strip arm 312 is installed by a self-tapping screw. The self-tapping screw is not completely tightened, so that the strip arm 312 swings back and forth with the movement rhythm of the walking mechanism 3.

[0021] like Figure 1 As shown, the V portion of the Y-shaped plate 31 is connected to the N-shaped plate 32, and the points of the Y-shaped plate 31 are fixedly connected to the two end points of the closed section of the N-shaped plate 32. The N-shaped plate 32 increases the contact area between the Y-shaped plate 31 and the ground, making the movement of the walking mechanism 3 more stable and less likely to fall over.

[0022] like Figure 1 As shown, the power source 4 is installed on the rear side of the back plate 13, and the power source 4 is connected to the motor 21 through electric wires.

[0023] The installation process of the utility model embodiment:

[0024] First, install the support shaft 111 on the outer side of the upper ends of the two side panels 11, and then install the motor 21 into the inner sides of the two side panels 11 and fix them with screws. The lower part of the motor 21 extends out of the two side panels 11, and an eccentric wheel 212 is installed on the outer side of the rotating shaft 211 on both sides of the lower part of the motor 21, ensuring that the installation angle of the crank 213 of the left and right eccentric wheels 212 is 180°.

[0025] Install the two ends of the closed section of the N-shaped plate 32 to the two end points of the V portion of the Y-shaped plate 31, and the open sections of the N-shaped plate 32 are arranged relatively to each other. Insert the support shafts 111 at the upper ends of the left and right side plates 11 into the slide grooves 311 of the two Y-shaped plates 31 respectively, and then screw the screws into the support shafts 111 to ensure that the support shafts 111 can slide freely in the slide grooves 311. Install a battery box on the rear side of the back plate 13, and the battery box contains a power supply 4. Then fix the back plate 13 to the side plate 11, and connect the wires of the power supply 4 to the motor 21. When the wiring of the wires is changed, the rotation direction of the motor 21 also changes, so that the bipedal robot can move forward or backward.

[0026] A strip arm 312 is installed at each self-tapping screw at the top of the Y-shaped plate 31I. The self-tapping screw is not completely tightened. When the walking mechanism 3 moves, the strip arm 312 swings back and forth with the movement rhythm of the walking mechanism 3.

[0027] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
