[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] Reference Figures 1 to 9This invention relates to a children's stroller, comprising a stroller body 100 and a shock-absorbing seat 200. The stroller body 100 includes a push frame 110 and two legs 120, namely a front leg 121 and a rear leg 122. The front leg 121 is rotatably mounted on the push frame 110, and the push frame 110 is rotatably mounted on the rear leg 122. Shock-absorbing casters 130 are provided at the lower end of each leg 120. The stroller body 100 has a folded state and an unfolded state. In the unfolded state, the push frame 110 rotates to an unfolded position relative to the rear leg 122, and the front leg 121 rotates to an unfolded position relative to the rear leg 122. In the folded state… In the state, the push frame 110 rotates to a position folded relative to the rear footrest 122, and the front footrest 121 rotates to a position folded relative to the rear footrest 122; the shock-absorbing seat 200 is installed on the vehicle body 100, and the shock-absorbing seat 200 includes a mounting frame 210, a seat body 220 and a shock-absorbing support structure (230). One end of the seat body 220 is pivotally connected to the mounting frame 210, and the other end of the seat body 220 is connected to the mounting frame 210 through the shock-absorbing support structure (230). The mounting frame 210 is installed on the vehicle body 100.

[0022] When the stroller is in use, the child sits on the seat body 220. If the ground is uneven, the vibration transmitted to the stroller body 100 can be suppressed by the shock-absorbing rollers, and the vibration transmitted to the seat body 220 can be suppressed by the shock-absorbing support structure (230), thus achieving a better shock absorption effect. Since the stroller body 100 can rotate, fold or unfold the push frame 110 and the front leg 121 relative to the rear leg 122, the stroller can also be folded to reduce the space occupied when stored, making it convenient for storage.

[0023] In the embodiments, reference is made to Figure 2 and Figure 3 The push frame 110 is provided with a seat avoidance area 111, and the shock-absorbing seat 200 is located in the seat avoidance area 111. The push frame 110 can swing relative to the shock-absorbing seat 200 to the front or rear of the stroller body 100. The push frame 110 can be reversed, that is, it can swing forward to the front area of ​​the stroller body 100 or swing backward to the rear area of ​​the stroller body 100, so that when an adult pushes the stroller, the child can face or turn away from them, thereby meeting different usage habits and making it more flexible to use; and because the push frame 110 avoids the shock-absorbing seat 200, that is, the push frame 110 can swing directly without the need to remove the shock-absorbing seat 200 in advance, the reversing process of the push frame 110 is more convenient.

[0024] In the embodiments, reference is made to Figure 3 and Figure 4The push frame 110 is provided with a first connecting part 112 and a second connecting part 113. The upper end of the front leg 121 is pivotally connected to the first connecting part 112, and the push frame 110 is pivotally connected to the rear leg 122 via the second connecting part 113. The first connecting part 112 and the second connecting part 113 are arranged at intervals. The vehicle body 100 also includes a limiting rod 140. One end of the limiting rod 140 is pivotally connected to the front leg 121, and the other end of the limiting rod 140 is pivotally connected to the rear leg 122. The limiting rod 140 is arranged at intervals with the first connecting part 112 and with intervals with the second connecting part 113. The vehicle body 100 described above can be folded or unfolded, and its folded volume is small, with a simple structure that is easy to implement.

[0025] It is conceivable that in other implementations, the vehicle body 100 may also be a folding structure in other ways, which can be selected by those skilled in the art according to actual needs.

[0026] In the embodiments, reference is made to Figure 4 and Figure 5 The push frame 110 includes a connecting rod 114 and an armrest 115. The end of the armrest 115 is pivotally connected to the first end of the connecting rod 114. In the folded state, the armrest 115 rotates to a position where it folds with the connecting rod 114. In the unfolded state, the armrest 115 unfolds relative to the connecting rod 114. When the push frame 110 is in the folded state, it can be further folded, reducing its length and thus further reducing the size of the folded vehicle body 100 for easier storage. When the push frame 110 is in the unfolded state, its length can be longer, allowing for a larger seat avoidance area 111, facilitating reversal to avoid the shock-absorbing seat 200.

[0027] In the embodiments, reference is made to Figure 3 The push frame 110 includes a connecting rod 114 and an extension rod 116. One end of the extension rod 116 is connected to the second end of the connecting rod 114, forming a second connecting portion 113. The other end of the extension rod 116 is pivotally connected to the front stand 121, forming a first connecting portion 112. The push frame 110, with its simple structure, forms a foldable function with the front stand 121 and the rear stand 122. The fewer the number of parts, the lighter the weight of the vehicle body 100, and the smaller its folded size.

[0028] Specifically, the folding process of the vehicle body 100 is as follows: the push frame 110 rotates and folds around the second connecting part 113, causing the extension rod 116 to drive the first connecting part 112 to rotate away from the rear foot 122. Then, under the action of the first connecting part 112 and the limiting rod 140, the front foot 121 moves closer to the rear foot 122, so that the push frame 110 and the front foot 121 can be folded relative to the rear foot 122. During this period, the handrail 115 of the push frame 110 rotates relative to the connecting rod 114, so that the handrail 115 can also be folded relative to the connecting rod 114, thus completing the folding process of the vehicle body 100.

[0029] Similarly, the unfolding process of the vehicle body 100 is as follows: the push frame 110 rotates and unfolds around the second connecting part 113, while the front leg 121 rotates and unfolds around the first connecting part 112, driving the limiting rod 140 to move, so that the push frame 110 and the front leg 121 can unfold relative to the rear leg 122; during this period, the handrail 115 of the push frame 110 rotates and unfolds relative to the connecting rod 114, completing the unfolding process of the vehicle body 100.

[0030] In the embodiments, reference is made to Figure 1 The shock-absorbing support structure (230) includes a compression spring, one end of which is connected to the seat body 220, and the other end of which is connected to the mounting frame 210. The rear end of the seat body 220 is supported by the compression spring, and the front end of the seat body 220 is pivotally connected to the mounting frame 210. The structure of the shock-absorbing seat 200 is relatively simple, and the shock absorption effect and support stability are good.

[0031] It is conceivable that the shock-absorbing support structure (230) could also be, for example, an elastic rubber block or other elastic components.

[0032] In the embodiments, reference is made to Figure 7 The shock-absorbing caster 130 includes a caster frame 131 and a roller body 132. The roller body 132 is rotatably connected to the caster frame 131 and the rotation axis is set in the horizontal direction. The caster frame 131 is rotatably set at the lower end of the footrest 120. The rotation axis of the caster frame 131 is perpendicular to the rotation axis of the roller body 132. A directional mechanism 150 is provided between the vehicle body 100 and the caster frame 131. The directional mechanism 150 can lock or unlock the position of the caster frame 131 relative to the footrest 120.

[0033] The orientation mechanism 150 can be used to lock or unlock the direction of a shock-absorbing caster 130 on a certain leg 120, making the forward direction of the stroller easier to control and more convenient to use.

[0034] Specifically, the shock-absorbing caster 130 can be made of elastic roller body 132, or a shock-absorbing component can be set at the universal wheel frame 131 to achieve the shock absorption effect. Those skilled in the art can choose according to actual needs.

[0035] In the embodiments, reference is made to Figure 3 and Figure 4 The push frame 110 can swing relative to the shock-absorbing seat 200 to the front or rear of the vehicle body 100. When the push frame 110 swings to the front of the vehicle body 100, it can lock the universal wheel bracket 131 at the front footrest 121 and unlock the universal wheel bracket 131 at the rear footrest 122. When the push frame 110 swings to the rear of the vehicle body 100, it can lock the universal wheel bracket 131 at the rear footrest 122 and unlock the universal wheel bracket 131 at the front footrest 121.

[0036] When the pusher 110 swings to the front of the vehicle body 100, the universal wheel bracket 131 of the front stand 121 is locked, and the universal wheel bracket 131 of the rear stand 122 is unlocked. The user stands in front of the vehicle body 100 to push the stroller. At this time, the direction of movement of the stroller can be adjusted by the universal wheel bracket 131 of the rear stand 122 to prevent the stroller from moving directly to the side. When the pusher 110 swings to the rear of the vehicle body 100, the universal wheel bracket 131 of the rear stand 122 is locked, and the universal wheel bracket 131 of the front stand 121 is unlocked. The user stands in the rear of the vehicle body 100 to push the stroller. At this time, the direction of movement of the stroller can be adjusted by the universal wheel bracket 131 of the front stand 121 to prevent the stroller from moving directly to the side. The aforementioned vehicle body 100 indirectly controls whether the universal wheel frame 131 can rotate through the push frame 110 and the orientation mechanism 150. The linkage is good, and there is no need to adjust the push frame 110 and the universal wheel frame 131 separately.

[0037] In the embodiments, reference is made to Figures 7 to 9 The orientation mechanism 150 includes a locking pin 151, a locking hole, and a transmission assembly. The locking hole is located on the caster frame 131. The locking pin 151 is slidably located on the foot bracket 120 and can be inserted into or disengaged from the locking hole. The pusher 110 can drive the locking pin 151 to be inserted into or disengaged from the locking hole through the transmission assembly. The axis of the locking hole is spaced apart from the axis of rotation of the caster frame 131.

[0038] The universal wheel frame 131 is restricted from rotating relative to the foot 120 by inserting the locking pin 151 into the locking hole; when the locking pin 151 is disengaged from the locking hole, the universal wheel frame 131 can rotate relative to the foot 120 to adjust its direction, and the push frame 110 controls the insertion or disengagement of the locking pin 151 through the transmission component. The control method is simple and reliable.

[0039] In the embodiments, reference is made to Figures 7 to 9The transmission assembly includes a pull rope 152, a first elastic element 153, a second elastic element 154, and a pressure pin block 155. The first elastic element 153 is disposed on the foot 120 and can drive the locking pin 151 to disengage from the locking hole. The pressure pin block 155 is slidably connected to the foot 120. The second elastic element 154 is disposed on the foot 120 and is used to drive the pressure pin block 155 to press the locking pin 151 into the locking hole. One end of the pull rope 152 is connected to the pressure pin block 155 and is used to pull the pressure pin block 155 away from the locking pin 151. The push frame 110 is driven by the pull rope 152. The stiffness coefficient of the second elastic element 154 is greater than that of the first elastic element 153.

[0040] When the pusher 110 pulls the rope 152 of one of the legs 120, the corresponding pressure pin 155 moves away from the locking pin 151 and compresses the second elastic element 154, causing the locking pin 151 to be pushed out of the locking hole by the first elastic element 153. At this time, the universal wheel frame 131 on the corresponding leg 120 is unlocked and can be adjusted. Then, the pusher 110 releases the rope 152 of the other leg 120. Since the stiffness coefficient of the second elastic element 154 is greater than that of the first elastic element 153, the second elastic element 154 drives the pressure pin 155 to press against the locking pin 151, causing the locking pin 151 to compress the first elastic element 153 and insert into the locking hole. At this time, the universal wheel frame 131 of the corresponding leg 120 rope is locked. The aforementioned orientation mechanism 150 enables the pusher 110 to indirectly control one leg 120 to lock the universal wheel frame 131, and the other leg 120 to unlock the universal wheel frame 131. The control method is relatively stable and reliable.

[0041] In the embodiments, reference is made to Figures 7 to 9 The transmission assembly also includes a third elastic element 156 and a transmission block 157. The push frame 110 is provided with a drive wheel 117 around its rotation axis. The outer periphery of the drive wheel 117 is provided with a clearance groove 1171 and a protrusion 1172. The transmission block 157 is connected to the other end of the pull rope 152. The transmission block 157 is slidably connected to the foot 120 and can approach or move away from the rotation axis of the drive wheel 117. The third elastic element 156 is provided on the foot 120 and is used to drive the transmission block 157 to approach the rotation axis of the drive wheel 117. The protrusion 1172 can push the transmission block 157 away from the rotation axis of the drive wheel 117. The transmission block 157 located on one foot 120 abuts against the protrusion 1172, and the transmission block 157 located on the other foot 120 is opposite to the clearance groove 1171. The stiffness coefficient of the third elastic element 156 is greater than that of the second elastic element 154.

[0042] When the pusher 110 swings to the front of the vehicle body 100, the transmission block 157 at the front support 121 is pushed away by the protrusion 1172 of the drive wheel 117, causing the third elastic element 156 to be compressed and the corresponding pull rope 152 to be released, thereby locking the swivel caster 131 at the front support 121. Since the stiffness coefficient of the third elastic element 156 is greater than the precision coefficient of the second elastic element 154, the transmission block 157 at the rear support 122 is pushed into the clearance groove 1171 by the third elastic element 156, that is, pulling the pull rope 152 at the rear support 122, thereby unlocking the swivel caster at the rear support 122. It can be understood that when the pusher 110 swings to the rear of the vehicle body 100, the movement states of the front support 121 and the rear support 122 are opposite. The aforementioned orientation mechanism 150 enables the universal wheel frame 131 of the front leg 121 and the rear leg 122 to unlock or lock when the push frame 110 swings, resulting in good stability during use.

[0043] Specifically, the first elastic element 153, the second elastic element 154, and the third elastic element 156 are all helical springs. It is conceivable that the first elastic element 153, the second elastic element 154, and the third elastic element 156 could also be elastic rubber blocks or other elastic structures; those skilled in the art can choose appropriately according to actual needs.

[0044] It is conceivable that the transmission assembly could also be other structures, such as the transmission assembly directly using a traction cable and an elastic element. The elastic element can push the locking pin 151 into the locking hole. One end of the traction cable is connected to the locking pin 151, and the other end of the traction cable is wound around the drive wheel 117. When the pusher 110 swings, it can directly pull or loosen the traction cable to pull out or insert the locking pin 151.

[0045] It is conceivable that the orientation mechanism 150 can also be other structures. For example, the orientation mechanism 150 includes an electric push rod and a controller. The telescopic end of the electric push rod has a locking block, and the fixed end of the electric push rod is mounted on the stand 120. By adjusting the controller when the push frame 110 swings, the locking block of the electric push rod on the corresponding stand 120 is engaged or disengaged from the slot of the universal wheel frame 131, thereby locking or unlocking the position of the corresponding universal wheel frame 131.
