[0033] Example

[0034] like Figure 1-6 As shown, an embodiment of the present invention provides a folding baby stroller, including a stroller body 1, wherein the stroller body 1 includes a folding base plate 11, folding side frames 12 symmetrically arranged on both sides of the folding base plate 11, and a support frame 13.

[0035] The folding base plate 11 includes a folding rod 111 and a base plate body 112 disposed on both sides of the folding rod 111. Support members 113 are provided at both ends of the base plate body 112 on the side away from the folding rod 111.

[0036] The folding side frame 12 includes an intermediate connector 121, and two telescopic rods 122 are movably arranged inside the intermediate connector 121. The bottom end of the telescopic rod 122 is movably connected to one of the support members 113, and a buckle 123 is provided on the telescopic rod 122.

[0037] The support frame 13 includes two symmetrically arranged uprights 131, the bottom end of which is fixedly connected to one of the support members 113.

[0038] like Figure 3 As shown, in some embodiments, both ends of the folding rod 111 are provided with folding connectors 114. One side of the base plate body 112 is fixedly connected to the two folding connectors 114 at both ends, and the other side of the base plate body 112 is movably hinged to the two folding connectors 114 at both ends through hinge joints 115.

[0039] The top of the folding connector 114 is closed, with the opening located at its bottom, so that the other base plate body 112 can be flipped relative to the folding connector 114 through the hinge joint 115, allowing the two base plate bodies 112 to be brought together and folded. At the same time, the design of the top of the folding connector 114 being closed ensures that the two base plate bodies 112 remain in position after being unfolded at 180 degrees, without excessive rotation, further ensuring the stability of the overall structure of the stroller.

[0040] like Figure 3As shown, in some embodiments, a plurality of reinforcing crossbars 116 and reinforcing longitudinal bars 117 are fixedly arranged inside the base plate body 112. The two ends of the base plate body 112 away from the folding bar 111 are respectively hinged to two support members 113, and a stabilizing bar 118 is fixedly arranged between the two support members 113.

[0041] The design of several reinforcing crossbars 116 and reinforcing longitudinal bars 117 ensures the structural strength of the base plate body 112. The hinged connection between the base plate body 112 and the support member 113 ensures that the wheel 119 does not need to rotate with the base plate body 112, so that the support member 113 drives the wheel 119 to always keep in contact with the ground, ensuring stability in the folded state. The setting of the stabilizer bar 118 further ensures the stability between the two support members 113.

[0042] like Figure 1 As shown, in some embodiments, the bottom of the support member 113 is movably provided with wheels 119, wherein two opposing wheels 119 are provided with synchronizing rods 1191 and brake rods 1192.

[0043] The four wheels 119 are located below the two support frames 13, and are divided into front wheels 119 and rear wheels 119. The synchronizing rod 1191 and the brake rod 1192 are installed on the two rear wheels 119. The synchronizing rod 1191 allows the two rear wheels 119 to turn synchronously, but they cannot rotate 360 ​​degrees like the front wheels 119. The brake rod 1192 is used to lock the rear wheels 119, so that the stroller remains immobile and is safer to use.

[0044] like Figure 3 As shown, in some embodiments, the telescopic rod 122 includes a sleeve 1221 and a sleeve rod 1222 movably sleeved inside the sleeve 1221. The opposite ends of the sleeve rod 1222 and the sleeve 1221 are respectively hinged to the intermediate connector 121 and the support member 113. A notch 1223 is provided on one end of the sleeve 1221.

[0045] When the stroller is folded, the telescopic rod 122 needs to be unlocked so that the sleeve 1222 can be pulled out from inside the sleeve 1221 to accommodate the raising of the intermediate connecting piece 121 in the folded state. When the telescopic rod 122 is locked, the intermediate connecting piece 121 cannot be raised, and the stroller cannot be folded. There are four telescopic rods 122, and the latches 123 on all four telescopic rods 122 need to be unlocked before folding. If some latches 123 on some telescopic rods 122 are accidentally unlocked, the remaining unlocked telescopic rods 122 will still prevent the stroller from being folded, further ensuring safety during use.

[0046] like Figure 3-5As shown, in some embodiments, the latch 123 includes a first fixing member 1231 and a second fixing member 1232. The first fixing member 1231 is sleeved on one end of the sleeve 1221. The bottom of the first fixing member 1231 is fixedly provided with a clamp 1233 that engages with the notch 1223. A latch plate 1234 is hinged to one side of the first fixing member 1231. The two ends of the latch plate 1234 away from the hinge are a locking part 1235 and an unlocking part 1236, respectively. The second fixing member 1232 is fixedly sleeved on the sleeve rod 1222. A latch 1237 that engages with the locking part 1235 is provided on one side of the second fixing member 1232.

[0047] Fixing component 1231 is secured to clamp 1233 by a screw. Clamp 1233 engages notch 1223, thus securing fixing component 1231 to sleeve 1221. Fixing component 2 1232 is secured to sleeve 1222 by a screw. Locking part 1235 is L-shaped. After locking part 1235 engages with buckle 1237, sleeve 1222 cannot be pulled out from inside sleeve 1221. When unlocking is required, lever principle is used. Pressing the unlocking part 1236 causes the locking part 1235 to pop up and disengage from the latch 1237, thus unlocking the latch 123. The sleeve 1222 can be pulled out from inside the sleeve 1221. When relocking, slide the sleeve 1222 inside the sleeve 1221 so that the second fixing part 1232 abuts against the first fixing part 1231. Pressing the locking part 1235 engages with the latch 1237, thus locking the device. The operation is simple and quick.

[0048] like Figure 4 As shown, in some embodiments, the interior of the intermediate connector 121 is also hinged with two surrounding rods 124 located above the two telescopic rods 122 respectively.

[0049] The opening of the middle connector 121 faces downwards, which is the same principle as the folding connector 114. This allows the two side rods 124 to remain in position after being unfolded at 180 degrees without excessive rotation, further ensuring the stability of the overall structure of the stroller. The inclined telescopic rod 122 further ensures the structural stability of the folding side frame 12.

[0050] like Figure 4 As shown, in some embodiments, the support frame 13 includes a second wall post 132 that connects two uprights 131 together via a corner connector 134, wherein the end of the corner connector 134 away from the second wall post 132 is hinged to one end of the first wall post 124.

[0051] The setting of the second guardrail 132 ensures the structural stability between the two uprights 131. It is used in conjunction with the first guardrail 124 to form a stroller fence. The end of the first guardrail 124 away from the middle connector 121 is hinged to the corner connector 134. The stroller is foldable, and the support frame 13 does not participate in the folding. The two support frames 13 move closer to each other as the folding base plate 11 and folding side frame 12 are folded.

[0052] like Figure 4 As shown, in some embodiments, the support frame 13 further includes handles 133 at both ends connected to the tops of two uprights 131 via connectors 135.

[0053] The connector 135 includes two turntables that are locked with screws. The handle 133 can be flipped and brought closer to the upright 131 through the connector 135, further reducing the space occupied by folding. The handle 133 makes it easier for users to push the stroller. The number of handles 133 is two, which allows users to freely choose to push the stroller from the front or the back, making it more convenient to use.

[0054] When in use, refer to the instructions when latches 123 are locked. Figure 1 After the latch 123 is locked, the telescopic rod 1222 cannot move relative to the sleeve 1221. The telescopic rod 122 pulls the intermediate connecting piece 121 relative to the support member 113, ensuring the stability of the folding side frame 12 and the folding base plate 11. To fold the stroller, press the unlocking part 1236 to disengage the locking part 1235 from the latch 1237, allowing the telescopic rod 1222 to move relative to the sleeve 1221. At this time, lift the folding rod 111, which lifts the folding connecting piece 114, allowing one of the base plate bodies 112 to pass through the hinge joint 1. 15. The relative folding connector 114 is flipped over. At this time, the two support frames 13 are pulled by the two base plate bodies 112 and move relative to each other, so that the two support frames 13 push against the first arm 124, so that the first arm 124 lifts the middle connector 121. The middle connector 121 rises and pulls up the sleeve 1222, so that the sleeve 1222 is partially pulled out from the inside of the sleeve 1221. When the folding rod 111 is pulled into place, the two telescopic rods 122 in the folding frame come together, and the two support frames 13 also come together, greatly reducing the size of the stroller and making it more convenient to carry.

[0055] In summary, this folding baby stroller features convenient and efficient folding operation. The telescopic rod 122 can be quickly released by pressing the unlocking part 1236 of the latch 123 using leverage. Locking is achieved simply by pressing the locking part 1235. During folding, the movement paths of the folding base plate 11 and the folding side frame 12 do not interfere with each other. The folding base plate 11 is flipped and brought together via a hinged connector, while the folding side frame 12 is raised by pulling away from the sleeve 1221 via the sleeve rod 1222. The coordinated movement of both is smooth, and the support frame 13 remains fixed and moves together smoothly. Combined with the wheels 119 always contacting the ground and the design of the stabilizing rod 118, the folding process is stable and reliable. The linkage mechanism of multiple latches 123 prevents accidental folding and allows for simultaneous unlocking when needed, balancing safety and ease of operation. Ultimately, this allows for rapid folding of the stroller and has broad application prospects.

[0056] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
