detailed description

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

Example 1

A riding suitcase, which realizes the combination of storage and riding, and realizes the function of changing long-distance dragging into long-distance riding. The specific composition is as shown in Figure 2. The box body includes: 4 side supports Rods 18, 4 top beams 19, 3 bottom beams 22, lower connecting rods 15, upper connecting rods 17, top plate 16, and bottom plate 21 are fixedly connected by corner connectors 20, and the bottom of tie rod 1 and bottom plate 21 are connected by bolts Connection, the top plate 16 has two holes, the pull rod 1 passes through the top plate 16, together with the outer cloth 23 and the zipper 24 to form the box part, the cloth 23 is covered and bonded to the outside of the box, and the ring-shaped zipper 24 is installed on the box The rear side, as shown in Figure 4.

As shown in Figures 1 and 3, the pedal transmission mechanism consists of two left and right pedals 7, a rope 6, a fixed pulley 4, two left and right connecting rods 10, two left and right vertical sliders 13, and two left and right vertical sliders. Guide rail 5, left and right 2 horizontal sliders 11, left and right 2 horizontal guide rails 14, left and right 2 rear wheels 12, the fixed pulley 4 is fixed to the upper connecting rod 17 by bolts, and the left pedal passes through the fixed pulley 4 through the rope 6 Connect with the right pedal, the left and right pedals 7 are connected with the vertical slider 13 by bolts, the left and right vertical sliders 13 buckle the two ends of the rope 6 respectively, and the left and right pedals 7 bypass the fixed pulley through the rope 6 4 and connected; the vertical guide rail 5 is connected with the side support rod 18 of the box by bolts, the vertical slider 13 and the vertical guide rail 5 form a sliding pair, the pedal 7 and the connecting rod 10 constitute a rotating pair, and the connecting rod 10 The other end forms a rotating pair with the horizontal guide rail 14; the horizontal slider 11 is connected to the bottom beam 22 of the box by bolts, and the inside of the rear wheel 12 is a ratchet mechanism, which is connected to the horizontal guide rail 14 by bolts, and the inner ring and the bolts are interference fit.

The brake mechanism is composed of two brake brakes 8 on the left and right, two brake handles 2 on the left and right, and a pull rod 1. The brake brake 8 is located in the upper front of the front wheel 9. The brake handle 2 is connected to the pull rod 1 through bolts, and the front wheel 9 is connected to the lower connecting rod 15. Attached, acts as a directional wheel. The ratchet mechanism inside the rear wheel 12 realizes that its inner ring does not rotate relative to the horizontal guide rail, while the outer ring can rotate freely forward in one direction; Moving downward, the left horizontal guide rail moves backward relative to the box through the connecting rod, that is, the left rear wheel moves backward relative to the box, but due to the action of the ratchet mechanism inside the left rear wheel, the left rear wheel cannot face oppositely The rear rolls, so it will have a forward speed; similarly, the right horizontal guide rail moves forward relative to the box, because the right rear wheel rolls forward without being affected by the inner ratchet of the ratchet, so the right rear wheel will also have a forward speed. Velocity, from which it will generally have a forward velocity, similarly when the right pedal is down and the left pedal is up, thus allowing the luggage case to move steadily forward. The brakes of the left and right front wheels are independent of each other, and the brakes can be achieved by tightening the left and right brake handles at the same time, or by tightening the brakes on one side, so that the front wheels on one side are rubbed, and the wheels on the left and right sides move forward at different speeds. The box turns and turns to the other side.

When used as an ordinary suitcase, the user stands on the side or in front of the suitcase, holds the handle bar with one hand and walks to realize dragging. The rear wheel is a ratchet wheel, which can only realize one-way rotation (counterclockwise rotation), and its rotation direction is the same as the person's forward direction. unanimous.

When riding, the user sits on the top plate, steps on the left and right pedals, holds the lever and the brake handle with both hands, and pushes the pedals to move the suitcase forward. The movement is similar, the box is the human body, the two ratchets correspond to the two feet respectively, the normal rolling of the ratchet forward is equivalent to the movement of the body moving forward with one foot in the air, and the rest of the ratchet because it cannot rotate backward is equivalent to the movement of a person stepping on the ground Only one foot provides forward acceleration for the box, and the ratchets on both sides alternately stand still and rotate to make the box move forward continuously, which is equivalent to the normal walking process of people.

When braking is required, the person pinches the brake handle hard, and the suspension wire is tightened, so that the two brake brakes pinch the front wheel to provide greater friction, limit the front wheel rolling, provide greater acceleration, and slow down the speed of the box, thereby realizing brake function. When you need to turn, squeeze the brake handle on one side tightly to limit the rolling of the front wheel on one side, so that the forward speed on both sides of the device is inconsistent, and the box rotates, thereby realizing the function of turning, and by changing the force of the brake handle , to adjust the speed difference, so as to adapt to various turning situations.
