Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model being described in further detail, is not that practical range of the present utility model is confined to this.
As shown in Figures 1 to 7, a kind of vehicle body with collapsible rear wheel mechanism described in the present embodiment, comprises body shell f1, also includes foldable rear-wheel device; Described rear-wheel device includes rear wheel f4, is articulated in body shell f1 and the fixed mount f5 of other end connection trailing wheel support arm f2 for trailing wheel support arm f2 and one end of rotating shaft connection rear wheel f4; Described body shell f1 holds the appearance frame groove of fixed mount f5 while being provided with fixed mount f5 folding. When folding, only need to, by fixed mount f5 bending, fixed mount f5 folding, holding f11 in frame groove, thereby being just folded to certain position, rear-wheel device be completed to turnover; By fixed mount f5 structure, realize a kind of vehicle body with collapsible rear wheel mechanism, convenient and practical, and hold frame groove and can effectively keep away position for trailing wheel support arm f2, scientific and reasonable, practicality is high.
A kind of vehicle body with collapsible rear wheel mechanism described in the present embodiment, body shell f1 rear end is provided with support bar f12; When use, described support bar f12 free end is against fixed mount f5. Support bar f12 first can strengthen trailing wheel support arm f2 in use with the fixation of body shell f1, secondly can prevent that trailing wheel support arm f2 from launching excessively, to cause the infringement of trailing wheel support arm f2.
A kind of vehicle body with collapsible rear wheel mechanism described in the present embodiment, support bar f12 is provided with a transverse axis bar f13, also include a switching mechanism, described switching mechanism includes the switch being slidably connected with fixed mount f5 piece f6, also include be located at switch between piece f6 and fixed mount f5, for make switch piece f6 reset elasticity block reset part; Switch is provided with one end of piece f6 the bar groove f61 that establishes transverse axis bar f13 for blocking. When use, by switch, piece f6 post-tensioning, bar groove f61 departs from transverse axis bar f13 thereupon, now, can carry out the jackknife action of trailing wheel support arm f2, otherwise, in launching, rear drag switch is piece f6, in launching to put in place, trip switch is piece f6, switch piece f6 because elasticity travels forward the effect of block reset part, until transverse axis bar f13 is fastened in bar groove f61, complete kayser action.
A kind of vehicle body with collapsible rear wheel mechanism described in the present embodiment, described body shell f1 bottom is also provided with a locator card hole f14, and described switch is provided with a card coordinating with locator card hole f14 the front end of piece f6 and establishes protruding f62. In the time of folding trailing wheel support arm f2, switch can be fastened on the projection of piece f6 in card hole, prevents that trailing wheel support arm f2 from disorderly shaking, and then prevents the damage of trailing wheel support arm f2.
A kind of vehicle body with collapsible rear wheel mechanism described in the present embodiment, described trailing wheel support arm f2 includes two the sub-support arms that can distinguish a trailing wheel of pivot joint, is provided with detachable material carrying basket f3 between two sub-support arms; It has improved practicality of the present utility model.
As Fig. 6 and Fig. 7, a kind of vehicle body with collapsible rear wheel mechanism described in the present embodiment, described body shell f1 bottom is provided with foldable foot-driven machine structure; Described foot-driven machine structure includes pole f7, and foot-driven machine structure can provide foot support for less children; Described pole f7, its one end and body shell f1 pivot joint, its other end is articulated with one group of foldable pin and steps on piece f71. Pin is stepped on piece f71, and to be articulated in pole f7 upper, make it possess pin step on piece f71 can folding, pole f7 also can folding function, improve folding function.
Concrete, a kind of vehicle body with collapsible rear wheel mechanism described in the present embodiment, described body shell f1 is provided with card ear f74; Described pole f7 and card ear f74 pivot joint; Also include for making foot-driven machine structure be folded to fixing turnover mechanism after different angles; Described turnover mechanism include be located on card ear f74 at least one ear draw-in groove f75, positioning tie bar f72 and make positioning tie bar f72 one end be arranged in the elastic component of ear draw-in groove f75. When use, drop-down positioning tie bar, the free end of positioning tie bar departs from ear draw-in groove f75, in the time that pole f7 is folded into the angle needing, unclamps positioning tie bar, and positioning tie bar can complete location because the effect of elastic component continues to be stuck in corresponding ear draw-in groove f75. Therefore, it is fixing that this structure can make foot-driven machine structure to stop in different angles, facilitates different children's needs.
A kind of vehicle body with collapsible rear wheel mechanism described in the present embodiment, described card ear f74 is two, and described pole f7 includes two sub bars, and sub bar is provided with directly to hole f73, described directly to one end of the sheathed positioning tie bar f72 of hole f73. The design of two card ear f74 and two sub bars, the foot-driven machine structure structure that can make is more reasonable, more firm.
A kind of vehicle body with collapsible rear wheel mechanism described in the present embodiment, described body shell f1 end face is provided with cushion. Cushion can improve children's comfort, improves experience sense of the present utility model.
The above is only a preferred embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the protection domain of the utility model patent application.
