[0031] For families with infants or children, the importance of strollers is self-evident. Strollers not only provide a safe and comfortable environment for children, but also offer convenience for parents, allowing them to simply push the stroller instead of carrying or holding the child when going out, thus reducing the burden of travel.

[0032] However, when encountering uneven or complex road conditions, making it inconvenient to push the stroller, parents usually need to lift the stroller, a process that is time-consuming and laborious, and difficult for one person to operate.

[0033] To solve the above-mentioned technical problems, this application provides a child stroller 100, please refer to [link / reference]. Figure 1 , Figure 1This is a schematic diagram of a child stroller 100 provided in some embodiments of this application.

[0041] Please refer to some embodiments of this application. Figure 1The trolley body 110 may also include an adjusting member 118. The armrest 112, the main body 113 and the support leg 114 intersect at the same position. The adjusting member 118 is set at this position to realize the rotational connection between the armrest 112 and the main body 113 and the rotational connection between the support leg 114 and the main body 113.

[0042] Please see Figure 1 and Figure 2 , Figure 2 for Figure 1 The diagram shows another angle of the stroller 100. The carrying strap 120 is located at the front of the stroller body 110. The carrying strap 120 may include a shoulder strap 121, a waist belt 122, a carrying strap body 123, a first connecting part 124, and a second connecting part 125. The carrying strap 120 is located at the front of the stroller body 110. The shoulder strap 121 and waist belt 122 are located on the side of the carrying strap body 123 away from the stroller body 110. The first connecting part 124 and the second connecting part 125 are located on the carrying strap body 123 close to the stroller body 110, and both the first connecting part 124 and the second connecting part 125 are provided on the carrying strap 120 body. The first connecting part 124 is detachably connected to the armrest 112, and the second connecting part 125 is detachably connected to the footrest 115.

[0043] In this way, when encountering uneven or complex road conditions that make it inconvenient to push the stroller 100, parents can carry the stroller 100 on their back using the shoulder strap 120 located at the front of the stroller body 110. After navigating uneven or complex road conditions, parents simply need to remove the shoulder strap 120 and put the stroller 100 down. The child can sit in the stroller body 110 throughout the entire journey, and can also experience a higher perspective, increasing the fun.

[0044] On the other hand, when no child is riding in the stroller body 110, parents can fold the stroller body 110 first through the adjustment piece 118, and then carry the stroller body 110 on their backs through the carrying strap 120, freeing their hands and improving the user experience.

[0045] In some embodiments of this application, please refer to Figure 3 , Figure 3 for Figure 2 The diagram shows the location of the first connecting part 124. The handrail 112 is also provided with a third connecting part, which may include a snap-fit ​​cavity 131 and a snap-fit ​​member 132. The snap-fit ​​cavity 131 may include a first snap-fit ​​opening 1311 and a second snap-fit ​​opening 1312. The first snap-fit ​​opening 1311 is oriented in a first direction, and the second snap-fit ​​opening 1312 is oriented in a second direction. The first direction and the second direction intersect.

[0046] The first direction can be the front-back direction, the second direction can be the up-down direction, the first gate 1311 faces forward, and the second gate 1312 faces down.

[0047] The first connecting part 124 may include a locking plate 1241, which extends into the locking cavity 131 through a first locking slot 1311, and a locking member 132 extends into the locking cavity 131 through a second locking slot 1312 and abuts against the edge of the second locking slot 1312.

[0048] The latching member 132 includes a locked position and an unlocked position. When the latching member 132 is in the locked position, the latching member 132 is latched with the card plate 1241, and the positions of the first connecting part 124 and the third connecting part are fixed. When the latching member 132 is in the unlocked position, the latching member 132 is disengaged from the card plate 1241, and the card plate 1241 can be pulled out of the latching cavity 131.

[0049] Thus, a detachable connection between the first connecting part 124 and the third connecting part is achieved by setting the card plate 1241 and the card connector 132.

[0050] Specifically, the card plate 1241 is provided with a card hole 1242, which is located in the card receiving cavity 131. At least part of the projection of the card hole 1242 onto the plane where the second card slot 1312 is located is located within the second card slot 1312.

[0051] The snap-fit ​​cavity 131 may include a mating inner wall 1313 opposite to the second snap-fit ​​opening 1312. In the direction from the second snap-fit ​​opening 1312 toward the mating inner wall 1313, the snap-fit ​​member 132 includes an extension 1321 and a mating portion 1322 connected in sequence.

[0052] The extension 1321 is located on the side of the card plate 1241 away from the first bayonet 1311, and the mating part 1322 is located on the side of the card plate 1241 away from the second bayonet 1312. The mating part 1322 has a tooth 1323 at one end facing the first bayonet 1311, and the free end of the tooth 1323 extends toward the second bayonet 1312.

[0053] The mating part 1322 is spaced apart from the mating inner wall 1313. The snap-fit ​​member 132 can reciprocate in the direction of the second snap-fit ​​1312 toward the mating inner wall 1313, so that the snap-fit ​​member 132 can switch between the locked position and the unlocked position. When the snap-fit ​​member 132 is in the locked position, the snap-fit ​​tooth 1323 extends into the snap-fit ​​hole 1242. When the snap-fit ​​member 132 is in the unlocked position, the snap-fit ​​tooth 1323 disengages from the snap-fit ​​hole 1242.

[0054] Thus, by engaging and disengaging the locking teeth 1323 and the locking holes 1242, a detachable connection is achieved between the locking member 132 and the locking plate 1241, thereby achieving a detachable connection between the first connecting part 124 and the third connecting part.

[0055] Wherein, at least a portion of the mating part 1322 is projected onto the plane where the second bayonet 1312 is located outside the second bayonet 1312, so as to prevent the snap-fit ​​part 132 from falling off the second bayonet 1312.

[0056] In some embodiments of this application, the side of the locking tooth 1323 facing the first locking slot 1311 is formed as a relief slope. When the locking plate 1241 is inserted into the locking cavity 131 by the first locking slot 1311, the locking plate 1241 abuts against the relief slope. Under the action of the relief slope, the locking member 132 moves in a direction away from the second locking slot 1312, and the locking hole 1242 can penetrate into the locking cavity 131.

[0057] Furthermore, the third connecting part may also include an elastic element 134, which is sandwiched between the mating part 1322 and the mating inner wall 1313, and applies a pushing force toward the second latch 1312 to the mating part 1322. Thus, when the latching hole 1242 on the latching plate 1241 extends into the latching cavity 131, under the action of the elastic element 134, the latching member 132 moves toward the second latch 1312, and the latching teeth 1323 engage with the latching hole 1242, thereby realizing the latching of the latching plate 1241 and the latching member 132.

[0058] The elastic element 134 can be a spring. The mating part 1322 is provided with a first mounting groove facing the mating inner wall 1313. The mating inner wall 1313 is provided with a second mounting groove opposite to the first mounting groove. The elastic element 134 is installed in the first mounting groove and the second mounting groove.

[0059] In some embodiments of this application, the latching member 132 may further include a push part 1324. The push part 1324 is connected to one end of the extension 1321 away from the mating part 1322. The projection of the extension 1321 onto the plane where the second latch 1312 is located is within the projection of the push part 1324 onto the plane where the second latch 1312 is located. That is, the cross-sectional area of ​​the extension 1321 is smaller than the cross-sectional area of ​​the push part 1324. By providing the push part 1324, the contact area between the latching member 132 and the user can be increased, making it easier for the user to apply force.

[0060] In the specific operation process, when the latching member 132 is in the locked position, the latching teeth 1323 engage with the latching hole 1242. When the user needs to separate the shoulder strap 120 from the trolley body 110, that is, when the first connecting part 124 needs to be separated from the third connecting part, the user only needs to push the push part 1324 to make the latching member 132 move towards the inside of the latching cavity 131, causing the latching teeth 1323 to disengage from the latching hole 1242, and then the latching plate 1241 can be pulled out of the first latching hole 1242.

[0061] Please refer to some embodiments of this application. Figure 3The first connecting part 124 also includes a fixing seat 1243, which is disposed on the main body of the shoulder strap 120. The card plate 1241 is rotatably connected to the fixing seat 1243. The card plate 1241 includes a use position and a storage position. When the card plate 1241 is in the use position, the card plate 1241 extends out of the fixing seat 1243. When the card plate 1241 is in the storage position, the card plate 1241 is stored in the fixing seat 1243.

[0062] Specifically, the main body of the shoulder strap 120 is plate-shaped. When the card holder is in the second position, the card plate 1241 is set parallel to the shoulder strap 120, reducing the space occupied by the shoulder strap 120 and making it easier to store the shoulder strap 120.

[0063] Specifically, the card plate 1241 and the fixed base 1243 are connected by a pivot to allow the card plate 1241 to rotate between the use position and the storage position.

[0064] Please refer to some embodiments of this application. Figure 4 , and refer to Figure 2 , Figure 4 for Figure 2 The diagram shows the location of the second connecting portion 125. The second connecting portion 125 includes a clearance section 1251 and a snap-fit ​​section 1252. One end of the clearance section 1251 is connected to the main body of the shoulder strap 120, and the other end extends toward the trolley body 110 and is connected to the connecting end of the snap-fit ​​section 1252. The free end of the snap-fit ​​section 1252 extends toward the bottom or top of the trolley body 110.

[0065] Specifically, the avoidance section 1251 is located on the upper side of the pedal rod 115, and the snap-fit ​​section 1252 is located on the rear side of the pedal rod 115. By hanging the second connecting part 125 on the pedal rod 115, the second connecting part 125 and the pedal rod 115 are detachably connected.

[0066] In particular, in the direction from the fixed end of the snap-fit ​​segment 1252 to the free end, the snap-fit ​​segment 1252 extends backward at an angle, which makes the distance between the free end of the snap-fit ​​segment 1252 and the strap body 123 larger, which is beneficial for hanging on the foot pedal 115.

[0067] In other embodiments of this application, please refer to Figure 5 , Figure 5 This is a schematic diagram of the second connecting portion 125 provided in some other embodiments of this application. The clearance section 1251 may be located on the lower side of the pedal rod 115, which is formed as a hollow structure rod with the opening facing downward. The snap-fit ​​section 1252 extends into the pedal rod 115 to realize a detachable connection between the second connecting portion 125 and the pedal rod 115.

[0068] Furthermore, there are multiple second connecting parts 125, which are spaced apart in the extending direction of the foot pedal 115. Thus, by providing multiple second connecting parts 125, the stability of the shoulder strap 120 when connected to the trolley body 110 can be ensured.
