The rotating part refers to that a front fork 14 is connected to a handlebar 13 through the head pipe 12, and the handlebar 13 operates the front fork 14 to rotate in the same direction. The front wheel 20 is pivotally connected to one end of the front fork 14 , and the rear wheel 21 is pivotally connected to one end of the rear fork 15 . In particular, the vehicle body 10 is not equipped with a transmission device, which cannot drive the rear wheels 21 to rotate on the vehicle body 10 .

The seat body 40 includes: two fixing seats 30 , a first plate 41 , a second plate 45 , two connecting rods 50 and a set of suction cups 60 . After the two sets of fasteners 31 are removed, the fixing seats 30 leave the vertically staggered first plate 41 and the second plate 45 , allowing the first plate 41 to leave the second plate 45 . Two spacers 43 are joined to both ends of the first plate 41 , and the thickness of the spacers 43 is equal to that of the second plate 45 . There are five suction cups 60 in this group, which are respectively arranged on the bottom surface of the two ends of the second plate 45 , the bottom surface of the intersecting part of the second plate 45 and the first plate 41 , and the bottom surface of the spacer 43 .

In addition, a coupling hole 51 is formed at two ends of each coupling rod 50 , and a protrusion 53 and a pin hole 54 are formed between the two coupling holes 51 . When the connecting rod 50 is inserted into a hole 46 of the second plate 45 , the pin hole 54 is exposed on the other side of the second plate 45 . When a pin 55 is inserted into the pin hole 54 , the protrusion 53 cooperates with the pin 55 to block both sides of the second plate 45 , so that the connecting rod 50 is combined with the end of the second plate 45 . At this moment, two snap rings 52 are disposed in the coupling holes 51 at both ends of the connecting rod 50 , and each snap ring 52 is exposed outside the second plate 45 .

Then see Figure 2 to describe the assembly work of the exerciser in detail. The rod 23 is tightened by the quick release 17 through the auxiliary pipe 16, so that the rod 23 is combined with the vehicle body 10. The guard 22 is an object drawn with a dotted line, which can be combined with the end of the rod 23 protruding from the secondary pipe 16 . When the ring body 24 is placed between the two outer rings 25, the shaft 27 passes through the ring body 24 and the outer ring 25, so that the three rods 23, 26 are connected together and can rotate around the shaft 27. The two rods 26 are respectively inserted into the fixing seat 30 , and the fixing seat 30 is locked on the top surface of the first plate 41 by the fastener 31 , so that the outer ring 25 is installed on the seat body 40 . The seat body 40 is connected with the vehicle body 10, and the vehicle body 10 swings back and forth around the shaft 27 relative to the seat body 40, so that the front wheels 20 and the rear wheels 21 contact the seat body 40 respectively.

When the fast release 17 releases the tightening relationship, the auxiliary pipe 16 and the rod 23 move with each other to adjust the position or height of the vehicle body 10 on the seat body 40 . The quick release 17 presses the spout binding lever 23 of the secondary pipe 16 to restore the tightening relationship again.

When the hook body 57 hooked the buckle 52, the two elastic cords 56 were respectively tied to the front wheel 20 and the rear wheel 21, and simultaneously applied two active forces in opposite directions to the vehicle body 10. When the two acting forces are roughly equal, the two front and rear wheels 20 and 21 are driven away from the second plate 45 , causing the vehicle body 10 to maintain a balanced state relative to the seat body 40 . The seat 40 can be placed on a supporting surface 62 (see FIG. 4 ), such as the ground.

In FIG. 3 , the assembly state of the seat body 40 is further described. Wherein, the fastener 31 is a stud, and the stud passes through the flange of the fixing seat 30, passes through a hole 42 of the first plate 41, enters a blind hole 49 of the second plate 45, and locks a nut 33 produces a tight binding effect.

At this moment, the rod 26 passes through a central hole 32 of the fixing seat 30 , and continues to go deep into a through hole 44 of the first plate 41 and a groove 47 of the second plate 45 , so that the outer ring 25 is mounted on the seat body 40 . In addition, a boss 61 of the suction cup 60 is combined with a concave portion 48 of the second plate 45, so that the weight summation of the exerciser is transferred to the suction cup 60, so that the suction cup 60 is tightly sucked on the support surface 62 (see Figure 4), so as to avoid any arbitrary movement of the exerciser. displacement.

During the initial period of the exercise, the vehicle body 10 is kept balanced as shown in FIG. 4 . Imagine a user (not shown in the figure) standing on the car body 10, holding the handlebar 13 with both hands, and stepping on the rear fork 15 with his feet.

When starting to practice, assume that the user changes the center of gravity of the vehicle body 10 as shown in FIG. 5 and operates the exercise device to swing forward. In response to the inclined vehicle body 10 , the front wheel 20 touches the second plate 45 , and the tension of the elastic cord 56 remains relaxed. At this moment, the rear wheel 21 is far away from the second plate 45 or the supporting surface 62, so that the tension of the elastic cord 56 remains in a tight state.

In FIG. 6 , the user pulls up on the handlebar 13 , lifts the front wheel 20 through the front fork 14 away from the second plate 45 or support surface 62 , and keeps the tension of the bungee cord 56 taut. The car body 10 changes the position of the center of gravity, and the user operates the exerciser to swing backward to an angle. At the same time, the rear wheel 21 contacts the second plate 45, allowing the tension of the elastic cord 56 to remain relaxed.

Simply put, the exerciser of this embodiment is placed in a limited space, and the two elastic cords 56 provide tension in turn to help the user operate the vehicle body 10 to swing back and forth relative to the seat body 40, so that the front wheels 20 and the rear wheels 21 are successively on the ground (i.e. contact seat body 40) to simulate the movement of soil slope or pump road.

During the exercise, the user stands up and falls backwards, or squats down and leans forward, actively changing the posture of the exercise. Under the operation of the user, the vehicle body 10 swings around the shaft 27 relative to the base body 40, passively changing the center of gravity of the exerciser. At this moment, the guard 22 prevents the body from colliding with the rod 23, which can protect the body without hindering the user from performing extreme sports training.

Fig. 7 is the second embodiment of the exerciser, its structure is roughly the same as that of the first embodiment, the difference lies in: one more buffer piece 63 is added. The buffer member 63 is arranged on the second board 45 to absorb the force of the front wheel 20 touching the second board 45 and slow down the impact force that the handlebar 13 gives back to the hands.

Fig. 8 is the 3rd embodiment of exercise device, and its structure is roughly the same as that of the first embodiment, and difference lies in: this ring body 24 is inserted between two lugs 65, and this shaft 27 passes through ring body 24 and side by side. The lugs 65 together form a pivot structure.

Of course, these lugs 65 stand on a support 64 which passes through the fixing seat, the first plate and the second plate, so that the lugs 65 are mounted on the seat.

Fig. 9 is a fourth embodiment of the exercise device, its structure is substantially the same as that of the first embodiment, the difference lies in that: the shaft 27 passes through a first blade 71 and a second blade 72 to form a hinge 70 together.

In addition, an open slot 23 a of the rod 23 receives the first blade 71 , and another set of fasteners 23 b locks the rod 23 and the first blade 71 . Each of the two rods 26a has an open slot 26c for receiving the second blade 72, and the other fastener 26b locks the second blade 72 and the rod 26a. The rod 26a is inserted into the central hole 32 of the fixing base 30, and the fixing base 30 is fixed on the base body 40, so that the hinge 70 is combined with the two fixing bases 30.
