A sole cushioning module includes a contacting plate, a base plate, a connecting portion and a first spring leaf. The contacting plate abuts against a sole. The base plate and the contacting plate form a space. The connecting portion connects with the contacting plate and the base plate. The first spring leaf is located within the space. The first spring leaf connects with the base plate. The first spring leaf is curved and forms a first outer curved surface. A first region of the first outer curved surface abuts against the contacting plate. When the contacting plate moves towards the base plate, the contacting plate presses on the first outer curved surface. The first spring leaf deforms, and the first outer curved surface slides relative to the contacting plate. The first region shifts towards an end of the first spring leaf connecting with the base plate.

The present invention discloses a movement facilitative device, basically comprising a first fixing module, a second fixing module, an energy storing module and a switching module, wherein the first fixing module and the second fixing module are fixed on the first extremity and the second extremity of the animal respectively. The first fixing module is connected with the second fixing module. The present invention has the advantages of decreasing the force required by the muscles during the exercise as well as retarding the impact enforced thereon while the user is jogging or exercising. Furthermore, the switching module of the present invention minimizes the limitations to the movement of the user so as to let the user exercise more effortlessly.

Movement facilitative device

An anti-rollover motorized vehicle includes a chassis, a front wheel and a rear two wheels assembly including a tilting base and a four-bar linkage structure. The tilting base is connected to the chassis through a supporting structure. The four-bar linkage structure suitable for connecting the chassis with two rear wheels includes first, second, third and fourth linkages. The first and second linkages are pivoted to the tilting base. The third and fourth linkages pivoted to two ends of the first and second linkages respectively are connected to the supporting brackets of the two rear wheels respectively. When the chassis is tilted, the tilting base and the supporting structure are also tilted, the first and second linkages are maintained at a constant angle relative to a road surface, and the third and fourth linkages are also tilted, such that track width of the two tilting rear wheels is maintained.

Anti-rollover motorized vehicle

A three-wheeled motor vehicle includes a main body, two shafts, two wheel bases, a blocking structure fixed to the main body and a linkage module. Each shaft has first, second and third pivot points. The third pivot point between the first and second pivot points is pivoted to the main body. One wheel base is pivoted to the first pivot points. The other wheel base is pivoted to the second pivot points. The wheel bases and the shafts form a parallelogram four bar mechanism. The linkage module is coupled between the main body and the parallelogram four bar mechanism. When the main body tilts as the three-wheeled motor vehicle turning, the linkage module changes from a first state to a second state to drive the wheel bases to tilt. The linkage module in the second state leans against the blocking structure to limit the tilt range of the wheel bases.

Three-wheeled motor vehicle with high safety

Disclosed is a safety device on a steering handle, capable of controlling a direction-control wheel of a wheeled vehicle. The handlebar is engaged with the head part by its mortise with a tenon of the head part. When an outer bar end of the handlebar is hit, an inner tube of the handlebar will be pushed to disengage the mortise and the tenon to rotate the handlebar along. Alternatively, paired washers with wedge-shaped teeth can be utilized to engage the handlebar with the head part. When the outer bar end is hit, the washers are disengaged to allow the handlebar to rotate. Moreover, a hydraulic system or an inserting rod with a chassis groove system can be employed to maintain the original direction of the direction-control wheel when the handlebar is hit. Therefore, a sudden turn of the direction-control wheel and an fall-over of the rider and the vehicle can be prevented.

Safety device on steering handle

A motor vehicle is provided. The motor vehicle comprises a vehicle body, a front wheel, a rear wheel and a tilting mechanism. The front wheel, the rear wheel and the tilting mechanism are disposed on the vehicle body. The tilting mechanism comprises a first compensation unit, a first arm, a first wheel, a second compensation unit, a second arm, a second wheel, at least one pipe and a fluid. The first arm is connected to the first compensation unit, and the first wheel. The second arm is connected to the second compensation unit, and the second wheel. The pipe connects the first compensation unit to the second compensation unit. The fluid flows in the first compensation unit, the second compensation unit and the pipe, wherein when the motor vehicle tilts, an extension length of the first compensation unit equals to a compression length of the second compensation unit.
