Referring to Fig. 1 to Fig. 5, the utility model elliptical walking trajectory exerciser includes: a base body 1 placed on the floor surface, the front end of the base body 1 is provided with a vertical bar 11 and a handle bar 13 for supporting , the vertical rod 11 is provided with an instrument panel 12 for computer control and display functions; a follow-up master control rod 2 is a rod body whose upper and lower sections are roughly parallel to the floor surface, and the follow-up master control rod 2 is passed through a pivot 14 The lower section is pivotally connected to the base body 1 and is in an upright state; the two sides of the upper section 21 of the follow-up master control lever 2 are respectively pivotally provided with first swing links 31, 32 and second swing links which are parallel to each other and have different lengths. Rod 33,34, the other end of the first swing link 31,32 and the second swing link 32,34 are pivotally fixed on one end of the middle link 41,42, and the other end of the middle link 41,42 is pivoted again. Rod 91,92 is pivotally connected with one end of right and left pedal connecting rod 51,52, and the other end of right and left pedal connecting rod 51,52 is respectively pivotally connected at the outer end of crank 61,62; The rear end of 1 is provided with resistance wheel 15 and driven wheel 16, utilizes drive belt 17 to connect resistance wheel 15 and driven wheel 16, the axle center of both sides of driven wheel 16 fixes left crank 62, right crank 61 with a shaft rod 7, and left and right sides The outer ends of the cranks 62, 61 are pivotally fixed on the left and right pedal connecting rods 52, 51 by the axle rods 72, 71; The user's left and right feet must exert force on the left and right pedal connecting rods 52, 51 and move the passive wheel 16 and the resistance wheel 15 to rotate, so as to achieve the purpose of fitness exercise. When the user's left and right feet continue to move one after the other, The left and right pedal connecting rods 52, 51 can simultaneously move the intermediate connecting rods 41 and 42, the first and second swinging connecting rods 31, 33/32, 34 to move forward and backward in opposite directions, because the first swinging connecting rods 31 and 32 , the second swing link 33 and 34, the middle link 41 and 42, etc., are designed according to the technology of Watt's approximate linear motion (WATT STRAIGHT LINEMECHANISM), so that the middle link 41, 42 and the right and left pedals are connected The rods 51, 52 can move close to a straight line at the pivot point P where the shaft rods 91, 92 are pivotally connected. As shown in FIG. The treads 51A, 52A on the connecting rods 51, 52 can present a more normalized elliptical motion trajectory, as shown in Figure 3, and at the same time allow the human foot to be able to move the entire sole of the foot under the condition of kinematics of the foot joint. It fits on the step seat, and makes the force-applying movement of the heel, heel and other parts enjoy a smoother, softer and more comfortable feeling, as shown in Figure 5. Moreover, the first and second swing links 31, 33/32, 34 all have the inertial force of swinging back at the two outer endpoints of the swing movement, so that the movement of the right and left pedal links 51, 52 will not occur. The stuttering phenomenon, that is, the treads 51A and 52A at the two ends of the elliptical long diameter of the movement trajectory will not produce a dead angle phenomenon, and thus can show a more coordinated and soft foot movement effect.

Referring to Figures 6 and 7, the utility model is pivotally provided with an electric motor seat 8 at the middle section 22 of the follow-up main control lever 2, and the electric motor seat 8 can act on a telescopic screw rod 81, and the other end of the telescopic screw rod 81 is pivoted. Located at the base body 1, when the electric motor seat 8 moves the telescopic screw rod 81 to elongate, it can push and raise the follow-up main control rod 2 due to the reverse force, because the first and second swing connecting rods 31, 33/32, 34, middle connecting rod 41/42, right and left pedal connecting rod 51/52 are the combination state that is connected, make the shaft rod 91, 92 ends of right and left pedal connecting rod 51, 52 relative to the other shaft rod The angles of 71 and 72 ends can present angle changes, and the start of the electric motor base 8 is controlled by microcomputer program design. This microcomputer program control technology is an existing and widely used technology, so it will not be repeated. When the angles of the right and left pedal connecting rods 51, 52 change, the athlete must exert different forces on the pedal connecting rods 51, 52, so as to achieve a wide variety of physical training. The motion tracks of the stepping rods 51 and 52 may be shown in FIG. 8 , which is different from that shown in FIG. 3 . The follow-up main control rod 2 of the utility model is provided with a pulley block 24 at the end of the upper section 21, and the pulley block 24 is stopped in the rail turn 18 of the vertical rod 11, and the follow-up main control rod 2 is raised by using the track turn 18. Or descending action can not produce lateral deviation, and pulley block 24 can reduce movement resistance.

Because of the design of the first swing connecting rod 31,32, the second swing connecting rod 33,34, and the middle connecting rod 41,42, the utility model enables one end of the pedal connecting rod 51,52 to move in a straight line, and at the same time Cooperate with the circular motion that is carried out at the other end of the crank 61,62 place, make the treads 51A, 52A on the pedal connecting rods 51,52 produce elliptical motion tracks, and because the first and second swinging connecting rods 31,32 The swing inertial force of /33 and 34 makes the exerciser's foot movement more smooth, coordinated, soft and comfortable, and because the follow-up master control rod 2 can be pushed up or down to change the pedal linkage The relative motion angles at the two ends of 51 and 52 enable practitioners to achieve physical training with different applied forces and to show the entertainment effect like walking up and downhill.

To sum up, the utility model elliptical walking trajectory exerciser has a scientific and reasonable structural design. It uses the electric motor to control and change the positioning angle of the main control rod, so that the movement trajectory of the pedal connecting rod can be changed in due course, allowing the practitioner to The effect of physical training can be achieved by different exertion exercises, and the application range is wide, which overcomes the defects of traditional products and achieves the expected design purpose.
