Detailed Description

The technical scheme of the utility model is further specifically described below through specific embodiments and with reference to the accompanying drawings.

Examples: the electric wheelchair and scooter suspension damping mechanism shown in fig. 1 to 5 comprises a frame body 1, a main board 3 and a damping bracket 2, wherein the main board 3 is obliquely arranged on one side of the frame body 1, the left side and the right side of the main board 3 are of symmetrical structures, and a first damping support 4 and a second damping support 5 are respectively arranged on the upper surface and the lower surface of the main board 3 by taking one side as an example; the two ends of the shock absorbing support 2 are respectively a first connecting seat 12 and a second connecting seat 13 corresponding to the first shock absorbing support 4 and the second shock absorbing support 5, a shock absorber 6 is rotationally connected between the first connecting seat 12 and the first shock absorbing support 4, the second connecting seat 13 and the second shock absorbing support 4 are directly rotationally connected, when the wheelchair or the scooter is used, the main board 3 is mainly subjected to force in the vertical direction, and the force applied by the main board 3 is mainly transferred to the second shock absorbing support 5 and the second connecting seat 13 positioned at the lower position, so the second shock absorbing support 5 and the second connecting seat 13 are main stress supporting points, when the force applied by the main board 3 is unstable, the shock absorbing support 2 has a rotating trend, the shock absorbing support 2 rotates around a rotating shaft between the second shock absorbing support 5 and the second connecting seat 13, and the shock absorber 6 between the first shock absorbing support 4 and the first connecting seat 12 can limit the shock absorbing support 2 to generate or float greatly, thereby the shock absorbing effect is realized. Wherein, shock absorber support 2 also is certain inclination and arranges to the first shock absorber support 4 on the first connecting seat 12 on the shock absorber support 2 and the mainboard 3 all are equipped with at the tip, and first shock absorber support 4 and first connecting seat 12 slope respectively set up on mainboard 3 and shock absorber support 2 simultaneously, and the position of first shock absorber support 4 and first connecting seat 12 corresponds each other, make the bumper shock absorber 6 between the two have certain horizontal position, so shock-absorbing structure in this scheme has the cushioning effect of horizontal direction, wheelchair or scooter have the shock-absorbing effect in the fore-and-aft direction of self promptly, the unstable problem when having optimized wheelchair or scooter start and stop improves user's experience and feel.

The shock absorber 6 both ends have the connecting hole and are connected through the pivot respectively with between first shock absorber support 4 and the first connecting seat 12 to the outside of shock absorber 6 is elastic component 7, and elastic component 7 is spring construction in this scheme, and the spring is inside to be telescopic link 8 structures, and when the bottom 3 dish atress about to take place to rotate, first shock absorber support 4 produces tensile or extruded effect to first connecting seat 12 through shock absorber 6, because the inside telescopic link 8 structures that have of shock absorber 6 to this tensile force or extrusion force are all absorbed by spring construction.

The shock absorber support 2 is equipped with the one end of second connecting seat 13 and is arc cornerite 14 structure to the protruding end of second connecting seat 13 setting at arc cornerite 14 is because the second shock absorber support 5 on the mainboard 3 and the second connecting seat 13 on the shock absorber support 2 are main atress point, and this end of shock absorber support 2 is the form of cornerite, can strengthen the structural strength of shock absorber support 2 on the one hand, and on the other hand arc cornerite 14 can increase the atress area of shock absorber support 2, bears most of the power.

And first connecting seat 12 and second connecting seat 13 on shock absorber support 2 set up in the same side of shock absorber support 2, and first shock absorber support 4 and second shock absorber support 5 then distribute in the upper and lower both sides of mainboard 3, and when first shock absorber support 4, second shock absorber support 5 and first connecting seat 12, second connecting seat 13 correspond to be connected, can form a class quadrilateral structure, can guarantee that mainboard 3 and shock absorber support 2 take place relative rotation, realize the absorbing effect. When the wheelchair or the scooter moves on an uneven road or one of the driving wheels 11 encounters an obstacle, the obstacle can cause the driving wheel 11 to lift, and as the shock-absorbing bracket 2 is fixedly connected with the driving device 10, the shock-absorbing bracket 2 can rotate upwards around the second shock-absorbing bracket 5 when the driving wheel 11 lifts, and the whole driving wheel 11 is jacked up and simultaneously compresses the shock absorber 6; after the obstacle is over, the driving wheel 11 rotates downwards around the second shock absorption support 5 under the action of dead weight and elastic restoring force of the shock absorber 6, so that the driving wheel 11 is reset, the main board 3 can be kept in a horizontal state in the whole process, and the wheelchair scooter can be kept in a horizontal stable state at any moment.

The other side of the shock absorption bracket 2, namely the side far away from the first connecting seat 12 and the second connecting seat 13, is fixedly connected with a driving device mounting seat 9, and a driving device 10 is arranged on the driving device mounting seat 9, wherein in the scheme, the driving device 10 adopts a motor; the motor is directly fixedly connected to the driving wheel 11. The driving device 10 is directly installed at the bottom of the shock absorption support 2, so that on one hand, the structure between the driving device 10 and the shock absorption structure is compact, the structural volume of the part is reduced, on the other hand, certain vibration can be generated when the driving device 10 operates, and the vibration generated by the driving device 10 can be quickly eliminated through the action of the shock absorption support 2 and the shock absorber 6, so that the user experience is improved. Wherein, the number of the motors is two, and the motors are respectively used for driving two driving wheels 11 of the scooter, and when the rotation speeds of the two motors are different, the turning function of the wheelchair scooter can be realized; the steering of the two motors can be controlled to realize the functions of forward and reverse.

The top of the main board 3 is protruding, the bottom is concave, and the middle part is hollowed out, so that on one hand, the weight of the main board 3 can be reduced, the material of the main board 3 is saved, on the other hand, the main board 3 also has higher bearing capacity and higher structural strength, and when a wheelchair or a scooter runs on a bumpy road, the wheelchair or the scooter still has stable and comfortable superior performance.

It should be noted that, the initial setting state of the elastic member 7 on the shock absorber 6 is a compressed state, on one hand, because the main board 3 is obliquely set, the main board 3 bears the dead weight of the scooter and has a tendency to rotate relative to the shock absorbing bracket 2, so the elastic member 7 on the shock absorber 6 is in a pre-compressed state, and on the other hand, the elastic member 7 is preset to be in a compressed state, so that the angle between the main board 3 and the shock absorbing bracket 2 is not too large, and the shock absorbing effect of the scooter can be rapidly absorbed. If the elastic member 7 is preset to be in a stretched state, the main plate 3 is subjected to a force in a direction away from the shock mount 2, which easily causes the main plate 3 to turn over or damage the shock absorber 6; the elastic member 7 is preset to be in a compressed state best.
