[0055] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0056] 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 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.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used herein 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.

[0058] Reference Figures 1 to 7 , an embodiment of the present application provides a foldable baby stroller, including:

[0059] A chassis 100, on which wheels 110 for supporting the walking of the baby stroller are installed;

[0060] A push handle rod 200, including a telescopic rod body 210 and a connecting seat 220 hinged at the bottom of the rod body 210. The connecting seat 220 is slidably installed on the chassis 100. A first sliding locking mechanism 120 is provided between the bottom of the rod body 210 and the chassis 100, and the first sliding locking mechanism 120 is unlocked in linkage with the telescoping of the rod body 210;

[0061] An inclined strut 300, connected to the push handle rod 200 through a first hinge point and forming a cage 310 with the push handle rod 200. The bottom of the inclined strut 300 is connected to the chassis 100 through a second hinge point;

[0062] A seat 400, connected to the push handle rod 200 through a third hinge point. The top of the inclined strut 300 is slidably installed on the seat 400. When the baby stroller is folded, the seat 400 approaches the chassis 100, and the cage 310 deforms accordingly.

[0063] The stroller has relative unfolded and folded states. Taking the unfolded state as an example, the attached figure has relative front and rear sides. According to the usage habit, generally, the top of the push handle rod 200 is arranged near the rear side, and a seat 400 is arranged on the front side. The diagonal brace rod 300 is used to connect the push handle rod 200 and the chassis 100, and its top is used to support the seat 400. In this embodiment, the bottom of the diagonal brace rod 300 is hinged to the rear side of the chassis 100. In the unfolded state (for reference, see Figure 3 ), the side surface of the cage 310 formed by the diagonal brace rod 300 and the push handle rod 200 is in an X shape. When the rod body 210 contracts, it drives the first sliding locking mechanism 120 to unlock. At this time, the connecting seat 220 slides forward relative to the chassis 100. Correspondingly, the cage 310 (the rod body 210 and the diagonal brace rod 300) moves towards the chassis 100 until the limit position, and at this time, the folding of the stroller is completed. The present application adopts a linkage unlocking method, making the folding of the stroller more convenient.

[0064] Of course, considering minimizing the height of the stroller after folding as much as possible, in this embodiment, the first hinge point is arranged close to the third hinge point.

[0065] Refer to Figures 1 to 12 . The rod body 210 includes a multi-stage unit rod 211 nested in a sliding manner. A second sliding locking mechanism 140 is arranged between adjacent unit rods 211. The top of the push handle rod 200 is provided with an unlocking member 149 that is linked with at least one second sliding locking mechanism 140. The unit rod 211 is hollow, and the specific number can be adaptively selected according to requirements. In the illustration of this embodiment (for reference, see Figure 3 ), the rod body 210 has three-stage unit rods 211, which are the unit rod 211a, the unit rod 211b, and the unit rod 211c from high to low. To avoid misoperation, the top of the push handle rod 200 is also provided with a secondary lock 160 acting on the unlocking member 149. When the secondary lock 160 is unlocked, the second sliding locking mechanism 140a between the top two-stage unit rods is unlocked through the unlocking member 149, and the second sliding locking mechanisms 140b between the remaining adjacent unit rods are unlocked by the pressure exerted by the higher-level unit rod during sliding. For easy understanding, refer to Figures 8 to 12 . A second sliding locking mechanism 140b is arranged between the unit rod 211b and the unit rod 211c. When the unlocking member 149 is operated, the unit rod 211a moves towards the bottom, and the bottom of the unit rod 211a will unlock the second sliding locking mechanism 140b during the sliding process. The unit rod 211b moves towards the unit rod 211c until the folding of the rod body 210 is completed.

[0066] The second sliding locking mechanism 140a further includes a linkage member 141 and a trigger block 142. From top to bottom, the two-way lock 160, the unlocking member 149, the linkage member 141, and the trigger block 142 are arranged in sequence, wherein the two-way lock 160 is used to drive the linkage member 141 to move synchronously. A socket 143 with an armrest 250 is fixed to the top of the unit rod 211a. The socket 143 has a first receiving groove 144a adapted to the trigger block 142 inside. A second elastic member is also provided between the trigger block 142 and the bottom of the first receiving groove 144a (when there is no external force interference, the top of the trigger block 142 protrudes from the socket 143). To achieve the locking function of the two-way lock 160, a positioning block 1411 is provided at the bottom of the linkage member 141, and an opening 1431 cooperating with the positioning block 1411 is provided at the top of the socket 143. In the locked state, the positioning block 1411 abuts against the end face of the socket 143 (the unlocking member 149 cannot be pressed). When the two-way lock 160 is slid, the linkage member 141 moves synchronously until the positioning block 1411 is opposite to the opening 1431. At this time, the unlocking member 149 can be pressed, and the linkage member 141 is driven to press the trigger block 142 downward.

[0067] To unlock between the unit rod 211a and the unit rod 211b, a first fixing seat 145a with a second receiving groove 144b is provided at the bottom of the unit rod 211a. A first movable pin 146a adapted to the unit rod 211b (with a first positioning hole 212a provided) and a third elastic member for driving the first movable pin 146a into the first positioning hole 212a are provided in the second receiving groove 144b. The trigger block 142 and the first movable pin 146a are linked through a second flexible member 150. Refer to Figures 10 to 12 , when the unlocking member 149 is pressed, the trigger block 142 moves downward. At this time, the second flexible member 150 pulls the trigger block 142 out of the first positioning hole 212a, realizing the unlocking of the second sliding locking mechanism 140a.

[0068] Further, refer to Figures 13 to 16 , the top of the unit rod 211c has a second positioning hole 212b. The second sliding locking mechanism 140b specifically includes:

[0069] A second fixing seat 145b, fixedly installed at the bottom of the unit rod 211b, with an axially arranged third receiving groove 144c inside;

[0070] A sliding member 147, slidably installed in the third receiving groove 144c, having an inclined guide groove 1471. The specific direction of the guide groove 1471 can be set according to requirements. In this embodiment, the higher side of the guide groove 1471 is close to the central axis of the unit rod 211b;

[0071] Wherein a horizontally arranged through hole 148 is provided between the second fixing seat 145b and the unit rod 211b;

[0072] The second movable pin 146b is horizontally arranged. One end is installed in the guide groove 1471, and the other end passes through the through hole 148 and cooperates with the second positioning hole 212b. Considering the stability during locking, in this embodiment, the number of the second movable pins 146b is 2, and the number of the corresponding guide grooves 1471 is also 2. The second movable pins 146b and the guide grooves 1471 are symmetrically arranged respectively;

[0073] The fourth elastic member is installed in the third receiving groove 144c to drive the second movable pin 146b into the second positioning hole 212b.

[0074] When the unit rod 211a contracts downward until the sliding member 147 is pressed downward, at this time, the guide groove 1471 moves downward synchronously, driving the second movable pin 146b to gradually move into the unit rod 211b until it disengages from the second positioning hole 212b. At this time, the second sliding locking mechanism 140b is unlocked, and the unit rod 211b can continue to move downward.

[0075] Reference Figures 13 to 17 , the chassis 100 is provided with a lock hole (not shown in the figure). The first sliding locking mechanism 120 includes:

[0076] The mounting seat 130 is fixedly inserted at the bottom of the rod body 210. The inside of the mounting seat 130 is provided with a receiving groove 131 that penetrates along the length direction of the rod body 210;

[0077] The locking pin 132 is slidably installed in the receiving groove 131, and the bottom of the locking pin 132 cooperates with the lock hole;

[0078] The trigger member 133 is triggered by the telescopic movement of the rod body 210 and drives the locking pin 132 to disengage from the lock hole;

[0079] The first elastic member is installed in the receiving groove 131 to drive the locking pin 132 into the lock hole.

[0080] Among them, the rod body 210 includes a multi-stage unit rod 211 that is slidably nested. The sliding locking mechanism is arranged on the lowermost unit rod 211 (the unit rod 211c in the attached drawing), and the unit rod 211 (specifically the unit rod 211b) adjacent to the lowermost unit rod 211 presses the trigger member 133 when sliding.

[0081] Specifically, the trigger member 133 and the locking pin 132 are linked through the first flexible member 135. The first reversing member 134 is installed in the receiving groove 131, and the first flexible member 135 bypasses the first reversing member 134. Reference Figures 13 to 16, when the trigger 133 moves downward, it drives the locking pin 132 to move upward out of the lock hole. At this time, the connecting seat 220 can slide along the chassis 100 for folding. Further, the locking pin 132 and the trigger 133 are both provided with strip holes 136, and a limiting member 137 extending into each strip hole 136 is fixed in the receiving groove 131 to limit the movement stroke of the locking pin 132 and the trigger 133.

[0082] In this embodiment, referring to Figures 17 to 19 , the chassis 100 includes a main beam 101 and cross beams 102 fixed at both ends of the main beam 101. Wheels 110 are respectively installed at the ends of each cross beam 102, and the connecting seat 220 is sleeved on the main beam 101. The cross beam 102 includes a first cross beam 103 and a second cross beam 104 arranged side by side. The first cross beam 103 is located at the front side, and the second cross beam 104 is located at the rear side. The main beam 101 is disposed at the middle position between the two. Of course, there is no specific requirement for the lengths of the first cross beam 103 and the second cross beam 104, and it is preferably that the two are of equal length. The diagonal braces 300 are two arranged side by side. The two diagonal braces 300 are respectively connected to the same cross beam 102 through corresponding second hinge points (hinged through the same pivot). The push rod 200 is located between the two diagonal braces 300. In this embodiment, the two diagonal braces 300 are of equal length and have the same hinged height. The cross-sectional shape of the diagonal braces 300 is not strictly limited, nor is it limited to being a straight rod. For example, it can be a bent pipe with a circular or oblong cross-section, etc.

[0083] To increase the structural strength, the tops of the two diagonal braces 300 are connected into an integral structure. Further, a sliding seat 301 is connected to the tops of the two diagonal braces 300 and is matched with the bottom surface of the seat 400 through the sliding seat 301. The tops of the two diagonal braces 300 are specifically rotatably connected to the sliding seat 301. The user can adaptively adjust the angle between the seat 400 and the diagonal braces 300 according to the usage habit and the folded state, and the applicability is stronger.

[0084] The bottom surface of the seat 400 has a sliding groove 410 that cooperates with the sliding seat 301, so that the distance between the seat 400 and the push rod 200 can be adjusted independently (the sliding seat 301 can slide forward / backward).

[0085] Further, the connecting seat 220 includes:

[0086] A sleeve 231, slidably sleeved on the main beam 101. The tube wall of the sleeve 231 is provided with an avoidance opening 232 for the locking pin 132 in the sliding locking mechanism to pass through;

[0087] Connecting arms 233, fixed in pairs on both sides of the avoidance opening 232. The bottom of the rod body 210 is hinged between the two connecting arms 233.

[0088] In the locked state, the locking pin 132 passes through the avoidance opening 232 and extends into the lock hole, locking the sliding seat 301 and the main beam 101 together.

[0089] A mounting seat 130 is fixed to the bottom of the rod body 210 and is hinged to the connecting arm 233 through the mounting seat 130. The mounting seat 130 also abuts against the outer wall of the sleeve 231, and the abutting parts have mutually adapted arc surfaces, so that the sleeve 231 and the mounting seat 130 will not interfere with each other when rotating.

[0090] Two hinge seats 240 are successively fixed on the push rod 200 from top to bottom, and are respectively hinged to the seat 400 (corresponding to the third hinge point above) and the diagonal brace 300 (corresponding to the first hinge point above).

[0091] Each hinge seat 240 is U-shaped as a whole, including a bottom part located at the bottom of the U shape and wing parts 241 located on both sides of the opening. The bottom is fixed to the push rod 200, and pivot shafts providing hinge points (corresponding to the second hinge point above) are respectively arranged through the wing parts 241, and the two pivot shafts move synchronously.

[0092] In order to further improve the expansion function, an armrest 250 is provided at the top of the push rod 200, and a canopy 260 is installed on the armrest 250. The canopy 260 can be folded and / or detachably connected, and can be selected according to actual needs.

[0093] Furthermore, a braking mechanism 270 that cooperates with at least one wheel 110 is installed on the chassis 100, and the braking structure can adopt the prior art.

[0094] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as the combinations of these technical features do not conflict, they should be considered to be within the scope described in this specification. When the technical features in different embodiments are shown in the same drawing, it can be regarded that the drawing also discloses the combination examples of the various embodiments involved at the same time.

[0095] The above-described embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting 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 deformations and improvements can still be made, and these all belong to the protection scope of the present application.
