The specific embodiment
With reference now to accompanying drawing, describe embodiments of the invention, in accompanying drawing, similar element numbers represents similar element.
Please refer to Fig. 1-2 b, described brake mechanism of baby carriage of the present invention and be arranged on a preferred embodiment on a pair of pushchair.As shown in the figure, described brake mechanism of baby carriage comprises a pair of brake hubs 11, a pair of foot piece 12, a pair of base 13, pair of wheels permanent seat 14, pair of resilient members 15, a wheel shaft 16 and an interlock pipe 17.Described wheel shaft 16 is arranged between a pair of pushchair 20, described a pair of brake hubs 11 is fixed on the inboard of corresponding pushchair 20, described a pair of foot piece 12 is enclosed within on described wheel shaft 16 and is corresponding with described a pair of brake hubs 11, and described a pair of base 13 correspondences are placed in described a pair of foot piece 12.Described pair of wheels permanent seat 14 and described pair of resilient members 15 correspondences are placed in described base 13, and the two ends of described wheel shaft 16 are passed described a pair of foot piece 12 and a pair of base 13 successively, finally insert the pushchair 20 of both sides.Described interlock pipe 17 is sheathed on described wheel shaft 16, and the two ends of described interlock pipe 17 are connected with described a pair of foot piece 12 respectively.In the present invention, because of the structure of the parts that are installed in respectively the brake mechanism of baby carriage on described a pair of pushchair 20 in full accord, therefore the present embodiment only is described the parts of the brake mechanism of baby carriage on the pushchair 20 that is loaded on a side wherein.
Particularly, as shown in Fig. 2 a and Fig. 2 b, described brake hubs 11 is fixed on the inboard of described pushchair 20, and described brake hubs 11 is provided with around described wheel shaft 16 and spaced apart some protruding 111, forms some draw-in grooves 112 between adjacent protrusion 111.Correspondingly, as shown in Figure 4, a side of described foot piece 12 protrudes out to described brake hubs 11 and forms brake rib 121.When needs brake, step on described foot piece 12, described foot piece 12 rotates, and makes described brake rib 121 stick in described draw-in groove 112, to realize brake; And need solution in a flash, and the user only need upwards lift described foot piece 12, and described foot piece 12 rotates, and just can make described brake rib 121 and described draw-in groove 112 break away from, to realize un-brake.Described brake mechanism of baby carriage is simple in structure, and the matching relationship between described brake rib 121 and described draw-in groove 112 is also simpler, and with low cost.
Refer again to Fig. 2 a, Fig. 2 b and Fig. 4, described foot piece 12 both sides are equipped with spacing hole 122 and the first mounting hole 123.In another embodiment of the present invention, a side of described foot piece 12 is provided with spacing hole 122.The part edge of described spacing hole 122 protrudes out formation one tongue piece 124 in described spacing hole 122, described tongue piece 124 is divided into the first sub-122a of spacing hole and the second sub-122b of spacing hole with described spacing hole 122.Preferably, described tongue piece 124 is a shell fragment.Correspondingly, the both sides of described base 13 are equipped with spacing preiection 131 and the second mounting hole 132.When described base 13 was placed in described foot piece 12, described spacing preiection 131 inserted in described spacing hole 122.Described wheel permanent seat 14 is provided with the 3rd mounting hole 141, described the 3rd mounting hole 141, the second mounting hole 132 align with described the first mounting hole 123, the first mounting hole 123, the second mounting hole 132 and the 3rd mounting hole 141 as described in as described in a connection piece 18 (as rivet) passes successively are to realize described wheel permanent seat 14, base 13 and to be connected the connection of foot piece 12.Because described tongue piece 124 is a shell fragment, when stepping on or lift described foot piece 12, described spacing preiection 131 interferes described tongue piece 124 to produce distortion, thereby make described protruding 131 can move between the described first sub-122a of spacing hole and the second sub-122b of spacing hole, thereby realize restriction and location to described foot piece 12 rotating distances.When described foot piece 12 was positioned at normal danger, namely described brake rib 121 sticked into described draw-in groove 112, and described protruding 131 are positioned at the described first sub-122a of spacing hole; When described foot piece 12 was positioned at the un-brake position, namely described brake rib 121 broke away from described draw-in groove 112, and described protruding 131 are positioned at the described second sub-122b of spacing hole.It should be noted that in another preferred embodiment of the present invention, described spacing preiection 131 is arranged on described foot piece 12, and described spacing hole 122 is arranged on described base 13, also can reach identical limit function.
It should be noted that brake mechanism of baby carriage of the present invention can realize that also one steps on the function of dual brake.Particularly, as shown in Fig. 1 and Fig. 2 a, described interlock pipe 17 is sheathed on described wheel shaft 16, and the both ends of described interlock pipe 17 are provided with a fluting 171 at least, are provided with at least a holding section 125 on the described foot piece 12 of both sides.After described brake mechanism of baby carriage assembling was completed, the holding section 125 of the described foot piece 12 of both sides was inserted respectively the described fluting 171 on described interlock pipe 17 accordingly.Therefore, when stepping on one of them described foot piece 12, described foot piece 12 rotates and will drive described interlock pipe 17 rotations, and the foot piece 12 of the other end of described interlock pipe 17 rotates thereby band is dynamically connected, realize the brake of the other end, and then realize that one steps on the function of dual brake.
In conjunction with Fig. 2 a and Fig. 3, a described base 13 of end conflict of described elastic component 15, the described wheel permanent seat 14 of other end conflict.Particularly, protruded out a fin 133 in described base 13, after described brake mechanism of baby carriage assembling is completed, a described fin 133 of end conflict of described elastic component 15.Such setting, when described brake mechanism of baby carriage ran into collision, described elastic component 15 can be brought into play certain shock-absorbing effect.
As shown in Figure 5, an embodiment of perambulator of the present invention comprises vehicle frame 30, a pair of pushchair 20 and a brake mechanism of baby carriage 100, and described pushchair 20 all is connected with described vehicle frame 30 with brake mechanism of baby carriage 100.Described brake mechanism of baby carriage 100 is described in detail in the above-described embodiments, and it can be applicable to different vehicle frame 30 and pushchair 20, does not repeat them here.
Above invention has been described in conjunction with most preferred embodiment, but the present invention is not limited to the embodiment of above announcement, and should contain various modification, equivalent combinations of carrying out according to essence of the present invention.
