[0043] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0044] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there may also be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0046] In this application, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity or order of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0047] See Figures 1 to 13 , this application provides a baby stroller 1000, as shown in Figure 3 , when two such baby strollers 1000 are arranged side by side, they can be spliced into a double baby stroller, corresponding to the following first baby stroller 1100 and second baby stroller 1200.

[0048] The baby stroller 1000 has an unfolded state and a folded state, and includes a left frame 100 and a right frame 200 which are oppositely arranged, and the two frames are symmetrically arranged. The left frame 100 includes a first left foot component 110, a second left foot component 120 and a left push handle component 130; the right frame 200 includes a first right foot component 210, a second right foot component 220 and a right push handle component 230. The first left foot component 110 and the first right foot component 210 correspond to each other and move synchronously, the second left foot component 120 and the second right foot component 220 correspond to each other and move synchronously, and the left push handle component 130 and the right push handle component 230 correspond to each other and move synchronously.

[0049] Among them, two of the first left foot component 110, the second left foot component 120, and the left push handle component 130 are hinged to each other, and the third one is at least hinged to one of them. Two of the first right foot component 210, the second right foot component 220, and the right push handle component 230 are hinged to each other, and the third one is at least hinged to one of them. For the convenience of description, taking one of the side frames as an example to illustrate the folding and unfolding of the stroller. When folding, the first left foot component 110 and the second left foot component 120 approach each other, and the left push handle component 130 rotates and approaches one of the left foot components. For example, the left push handle component 130 rotates and approaches the first left foot component 110 or rotates and approaches the second left foot component 120.

[0050] A connecting member 300 is rotatably provided on the first left foot component 110, and the connecting member 300 has:

[0051] A first position. When the stroller 1000 is in the folded state, the connecting member 300 acts on the left push handle component 130 or the second left foot component 120 to restrict it from moving away from the first left foot component 110, that is, to keep the stroller 1000 in the folded state.

[0052] A second position, for connecting another stroller arranged side by side. The connecting member 300 acts on the first right foot component of the other stroller to restrict the separation of the two strollers. For example, the connecting member 300 of the first stroller 1100 is connected to the first right foot component 210 of the second stroller 1200.

[0053] Therefore, for the stroller of the present application, the connecting member on the foot component can connect to another foot component or the push handle component to keep the stroller in the folded state when folding the single stroller, and when splicing two strollers side by side, switch positions to connect to another stroller to restrict the separation of the two strollers. The manufacturing cost is reduced, and the connecting member is always connected to the foot component, without the need to disassemble and store it separately, and it is not easy to lose.

[0054] The structure of the stroller 1000 is as Figure 1 and Figure 2 shown. The first left foot component 110 and the first right foot component 210 are the rear feet, and a cross bar is connected between the two rear feet. The second left foot component 120 and the second right foot component 220 are the front feet, and the bottoms of the two front feet are connected. The tops of the left push handle component 130 and the right push handle component 230 are connected. Taking the left side frame 100 as an example: The left push handle component 130 and the first left foot component 110 are hinged around the first axis, and the second left foot component 120 and the first left foot component 110 are hinged around the second axis. The stroller 1000 includes a connecting rod. When folding, the left push handle component 130 rotates and approaches the first left foot component 110, and drives the second left foot component 120 to rotate and approach the first left foot component 110 through the connecting rod. Since there is a linkage relationship between the left push handle component 130 and the second left foot component 120, therefore, the connecting member 300 acting on the left push handle component 130 can keep the stroller in the folded state.

[0055] See especially Figure 6 and Figure 7 as well as Figure 10 and Figure 11 In one embodiment, the first right foot assembly 210 is provided with a first engaging portion 211, and the connecting member 300 is provided with an engaging hole 310. When the connecting member 300 is in the second position, the first engaging portion 211 extends into the engaging hole 310 to prevent the two baby carriages from separating. During actual operation, first switch the connecting member 300 to the first position, then bring the two baby carriages close to each other side by side, and then switch the connecting member 300 to the second position, that is, extend the first engaging portion 211 into the engaging hole 310.

[0056] Wherein, an anti - detachment structure is provided between the connecting member 300 and the first engaging portion 211 to prevent the first engaging portion 211 and the connecting member 300 from detaching during the running of the double - baby carriage, which may affect the use. As shown in the figure, the anti - detachment structure includes:

[0057] A locking groove 212, provided on the first engaging portion 211;

[0058] A locking member 320, slidably provided on the connecting member 300, and having a locked state in which it extends into the locking groove 212 to restrict the first engaging portion 211 from disengaging from the engaging hole 310, and an unlocked state in which the first engaging portion 211 is allowed to disengage from the engaging hole 310;

[0059] A first elastic member 330 (such as a spring), provided on the connecting member 300 and acting on the locking member 320 to keep it in the locked state.

[0060] Combined with Figure 9 In, the locking member 320 includes a body 321 slidably embedded in the locking member 320 and an operating portion 322 exposed outside the locking member 320. A part of the body 321 is located in the engaging hole 310 in the locked state of the locking member and is used to extend into the locking groove 212. In a preferred embodiment, see Figure 6 and Figure 7 , the first left foot assembly 110 is provided with a first left wheel seat 112 for installing a first left wheel 111, the connecting member 300 is rotatably provided on the first left wheel seat 112. Correspondingly, the first right foot assembly 210 is provided with a first right wheel seat 214 for installing a first right wheel 213, and a bump serving as the first engaging portion 211 is provided on the first right wheel seat 214.

[0061] See Figure 7 and Figure 8, in one embodiment, one of the first left-foot assembly 110 and the first right-foot assembly 210 is provided with a bolt 215, and the other is provided with a slot 113 that cooperates with the bolt 215 for splicing two strollers arranged side by side. In the illustration, the bolt 215 is provided on the first right-wheel seat 214, and the slot 113 is provided on the first left-wheel seat 112. When the two strollers are spliced, the bolt 215 and the slot 113 are inserted and matched to restrict the relative movement of the two strollers in the plane 400 perpendicular to the insertion direction, that is, it plays a certain positioning role, facilitating the first joint portion 211 to extend into the joint hole 310 when the subsequent connecting member 300 rotates to the second position.

[0062] Refer back to Figure 5 , in one embodiment, the left push handle assembly 130 or the second left-foot assembly 120 is provided with a second joint portion 131, and the connecting member 300 is provided with a joint hole 310. When the connecting member 300 is in the first position, the second joint portion 131 extends into the joint hole 310. Combining the above-mentioned stroller structure, the left push handle assembly 130 includes a push rod in a rod shape, and a card seat with the second joint portion 131 is fixedly arranged on the push rod. During actual operation, the connecting member 300 can be first switched to the second position, and after the stroller is folded, the connecting member 300 is then switched to the first position so that the second joint portion 131 extends into the joint hole 310. The structure of the second joint portion 131 can refer to the aforementioned first joint portion 211, or it can be a block shape as shown in the illustration without a structure similar to a locking groove.

[0063] Among them, refer to Figure 10 , Figure 12 and Figure 13 , when the connecting member 300 rotates from the second position to the first position, it is the first direction, and the opposite direction is the second direction. The connecting member 300 is provided with an arc surface 340 extending along the rotation axis. A limiting member 114 is provided on the first left-foot assembly 110. When the connecting member 300 is in the first position, the limiting member 114 acts on the first end surface 341 of the arc surface 340 to restrict the connecting member 300 from rotating in the first direction. When the connecting member 300 is in the second position, the limiting member 114 acts on the second end surface 342 of the arc surface 340 to restrict the connecting member 300 from rotating in the second direction.

[0064] In a preferred embodiment, the arc surface 340 includes an arc segment 343, and a first limiting groove 345 and a second limiting groove 346 connecting the two ends of the arc segment 343. The first limiting groove 345 and the second limiting groove 346 are radially recessed relative to the arc segment 343. For example, it can be a V-shaped structure as shown in the illustration. Correspondingly, the end of the first limiting member 114 that cooperates with the limiting groove is V-shaped.

[0065] One side wall of the first limiting groove 345 is the first end face 341, and the other side wall is the first guiding inclined surface 3451. One side wall of the second limiting groove 346 is the second end face 342, and the other side wall is the second guiding inclined surface 3461. A second elastic member 344 is arranged on the first left foot assembly 110. Under the action of the second elastic member 344, the limiting member 114 extends into the corresponding limiting groove. When the connecting member 300 switches between the first position and the second position, the limiting member 114 slides through the guiding inclined surface to compress the second elastic member 344.

[0066] To further maintain the stable connection of the double baby stroller, refer back to Figures 1 to 3 , the baby stroller 1000 includes a left magnetic attracting member 140 arranged on the left frame 100 and a right magnetic attracting member 240 arranged on the right frame 200. When two side-by-side baby strollers are spliced, the left magnetic attracting member 140 and the right magnetic attracting member 240 attract each other to better maintain the stability of the double baby stroller.

[0067] Among them, the left magnetic attracting member 140 and the right magnetic attracting member 240 are correspondingly arranged in multiple groups, and each group includes a left magnetic attracting member 140 and a right magnetic attracting member 240. In the figure, the first left push handle assembly 130 and the first left foot assembly 110 are hinged through a first rotating joint, and a left magnetic attracting member 140 is arranged at the first rotating joint. The first left push handle assembly 130 includes an upper push rod 134 and a lower push rod 133 that are rotationally matched, and the upper push rod 134 and the lower push rod 133 are hinged through a second rotating joint, and a left magnetic attracting member 140 is arranged at the second rotating joint. Correspondingly, a right magnetic attracting member 240 is arranged at the corresponding joint of the right frame.

[0068] Further preferably, one of the left magnetic attracting member 140 and the right magnetic attracting member 240 is provided with a positioning groove 241, and the other is provided with a positioning block 141 adapted to the positioning groove 241. In the figure, when two side-by-side baby strollers are spliced, the positioning block 141 of the left magnetic attracting member 140 extends into the corresponding positioning groove 241 of the right magnetic attracting member 240 for splicing positioning, that is, restricting the relative movement of the two baby strollers in the aforementioned plane 400. Among them, the left magnetic attracting member 140 includes a first base, and the positioning block 141 is slidably installed in the base. When the two baby strollers are spliced, the positioning block 141 can extend out of the base under the action of magnetic force and extend into the positioning groove 241.

[0069] For the baby stroller of the present application, the connecting member on the foot assembly can connect to another foot assembly or push handle assembly when the single baby stroller is folded to keep the baby stroller in a folded state, and when two baby strollers are side-by-side spliced, it switches positions to connect to another baby stroller to restrict the separation of the two baby strollers. The manufacturing cost is reduced, and the connecting member is always connected to the foot assembly without disassembly and storage, and is not easy to lose.

[0070] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification. When the technical features in different embodiments are embodied in the same drawing, the drawing can be regarded as also disclosing the combined examples of the various embodiments involved.

[0071] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application.
