Below do explanation with regard to the front shock-proof device structure of this utility model preferred embodiment with back shock-absorbing structure and manner of execution respectively.

(1) front shock-proof device of present embodiment structure:

The structure and the assembling mode of front-wheel shock-absorbing structure, ask for an interview Fig. 2 and shown in Figure 3, the front-wheel shock-absorbing is configured to a kind of anti-vibration structure of horizontal, have left and right shock-absorbing

arm

80,81, a shock-absorbing element 82 and a shock-absorbing support 83, wherein, earlier that linkage frame 35 before front support stand 41,42 usefulness one is affixed with the screw spiral pin with shock-absorbing support 83, allow a pair of shock-absorbing

arm

80,81 and shock-absorbing support 83 be articulated again, and an end of each shock-absorbing

arm

80,81 is connected with the last front wheel carrier 310 of front-wheel member 31 respectively, the other end then mutually in the face of and keep suitable distance; The spring 820 that shock-absorbing element 82 is put by a level and one is constituted by the sheathed bent rod 821 that is bent upwards suitable radian of spring 820, bent rod 821 is to make with vulcanie, using vulcanie is to get its pliability and have suitable resilient characteristic, so when spring 820 curved by the time be subjected to the restriction of bent rod 821, make spring 820 bending energies present suitable flexibility, then, two ends with shock-absorbing element 82 are connected to a left side with screw rod 822 screw locks respectively again, right shock-absorbing

arm

80,81 opposed facing two ends, so, promptly finish the assembling of as shown in Figure 3 front-wheel shock-absorbing structure and small-sized walking-replacing tool.

At this, with off-front wheel 34 is example, when the off-front wheel 34 of small-sized walking-replacing tool passes through the road surface of projection, as shown in Figure 5, right shock-absorbing arm 81 is that pivotal point 830 is done the action that upwards pivots with the right of shock-absorbing support 83, briefly be that right shock-absorbing arm 81 is lifted, because right shock-absorbing arm 81 makes the right-hand member of the spring 820 of shock-absorbing element 82 be bent upwards when lifting jointly, in spring 820 diastrophic processes, constantly absorb simultaneously the energy that right shock-absorbing arm 81 lifts the impact load, right shock-absorbing arm 81 can be lifted with attitude stably, so, concerning the occupant, do not have the sensations that off-front wheel 34 rises suddenly when off-front wheel 34 during through the high spot on road surface.

Opposite, if the off-front wheel 34 of small-sized walking-replacing tool has arrived recessed low road surface, it is the pocket that off-front wheel 34 has been fallen the road surface, this moment, a counter-force that makes progress was executed to off-front wheel 34 in ground, and the strength that makes progress to make right shock-absorbing arm 81 be that pivotal point 830 is done the action that upwards pivots with the right of shock-absorbing support 83, ensuing action details as aforementioned off-front wheel 34 through the bump places.And when off-front wheel 34 desires from the road surface recessed lower climb when playing evenness of road surface, the off-front wheel 34 of smooth road surface for being positioned at pocket, as from a smooth road surface to a bump, therefore, the action of the front shock-proof device structure on the right is also moved through the mode at bump place according to aforesaid off-front wheel 34, no longer illustrates at this.

So, by preceding described with can clearly be seen that from Fig. 5 seat A during through the road surface that rises and falls, remains level at off-front wheel, so, can allow the occupant can not rock because of the fluctuating on road surface.

(2) the back shock-absorbing structure of present embodiment:

The structure and the assembling mode of trailing wheel shock-absorbing structure, ask for an interview Fig. 2 and shown in Figure 4, trailing wheel shock-absorbing structure 9 is that a kind of vertical type spring 90 is as main shock absorbing apparatus, one end of pair of rear wheels shock-absorbing structure 9 is connected to left and right rear support stand 51,52 respectively, and the other end is connected to and respectively strengthens bogie side frame 61,62, so, can absorb the vibrations of left and right trailing wheel 64,65 by trailing wheel shock-absorbing structure 9.

At this, with left rear wheel 64 is example, when the left rear wheel 64 of small-sized walking-replacing tool passes through the road surface of projection, as shown in Figure 6, because the rising (through the high spot on road surface) of left rear wheel 64 has driven cantankerousization bogie side frame 61 and has done pivot with the pivoting point 64 of left front bracing frame 41, meaning is that the rear end of cantankerousization bogie side frame 61 is lifted, then, the vertical type spring 90 of trailing wheel shock-absorbing structure 9 is compressed because of lifting of cantankerousization bogie side frame 61 rear ends, and then the energy of impact load when absorbing cantankerousization bogie side frame 61 and lifting, so can make the cantankerousization bogie side frame 61 can be to be lifted reposefully, so when left rear wheel 64 tunnel during through the high spot on road surface, for the occupant, left rear wheel 64 buckets do not have the sensation of unexpected rising.Again, when cantankerousization bogie side frame 61 lifts, can make reinforcement after-frame 63 strengthen bogie side frame 62 with the right side jointly is lifted, be that to strengthen framework 6 be wholely upwards to lift, this represents that this preferred embodiment not only can absorb outside the energy by the trailing wheel shock-absorbing structure 9 on the left side, more can be with energy by strengthening the trailing wheel shock-absorbing structure 9 that after-frame 63 passes to the right, with the energy that disperses to lift.What this must emphasize once more be,, please see shown in Figure 1ly again, also can produce a moment simultaneously, can allow the occupant that the kind sensation of jack-up is forward arranged though known back shock-absorbing support 12 also is whole being lifted; Yet preferred embodiment of the present utility model is to strengthen framework 6 merely upwards to lift, and can not produce moment.

When small-sized walking-replacing tool left rear wheel during through recessed low road surface, what this must illustrate earlier be, please see shown in Figure 2 again, because the center of gravity (buttocks storing place of seat A) of the weight of occupant own is near back shock-absorbing structure 9, so can allow back shock-absorbing structure 9 bear bigger strength, therefore can allow the vertical type spring 90 of trailing wheel shock-absorbing structure 9 do earlier compression slightly, when the occupant takes seat, vertical type spring 90 can keep the state of compression, so well imagine, when left rear wheel 64 has arrived the recessed lower in road surface, the vertical type spring 90 of trailing wheel shock-absorbing structure 9 can allow left rear wheel 64 touch recessed low ground because of elastic recovery pushes away cantankerousization bogie side frame 61 downwards, ground is executed a counter-force again and is given left rear wheel 64 then, left rear wheel 64 passes to strength the cantankerousization bogie side frame 61 on the left side again, make cantankerousization bogie side frame 61 rear ends upwards lift again, the manner of execution of trailing wheel shock-absorbing structure 9 did not repeat them here when following step was passed through the road surface of projection as left rear wheel 64.By this, cantankerousization bogie side frame 61 can lift with attitude stably, so when left rear wheel 54 tunnel during through the recessed lower on road surface, can allow the occupant that the sensations that left rear wheel 64 reduces are suddenly lowered.

In sum, the difference of the utility model and known forward and backward shock-proof structure is: this reality Construct as the front shock-proof device of small-sized walking-replacing tool with novel shock-proof structure with horizontal, and this horizontal Shock-proof structure can avoid front-wheel that unexpected rising or reduction are arranged except making front-wheel when the up-and-down road surface Sensation outside, more can make seat maintenance level, and can not allow the occupant rock, this is the utility model One of place of more known progress; And aspect rear shock-proof structure, although the utility model and knownly all be Use a pair of spring that stands vertically as the element of main shock-absorbing, but because the difference of body Structure, Can allow the utility model can be such as known configuration through the fluctuating road surface time, produce moment and allow the occupant have A kind of by the sensation of jack-up forward.
