[0038] Refer to Figure 1 、 Figure 2 As shown, in one embodiment of the present application, a trolley 100 is disclosed, including:

[0039] A trolley main body having an accommodation space 120, including a side enclosure component 130 and a bottom support component 140 that enclose the accommodation space 120. The side enclosure component 130 includes a pair of first side frames 131 extending in a first direction;

[0040] A seat 200, including a seat component 210, a side guard component 230 connected to each other, and a backrest component 220 hinged to the seat component 210. The seat 200 is placed in the accommodation space 120 and is hung on the first side frame 131 through a connecting member 240 fixed on the side guard component 230;

[0041] An adjusting component 300, one end of which is connected to the backrest component 220, and the other end is connected to the side enclosure component 130 or the side guard component 230 or the seat component 210. The adjusting component 300 has a locked state that restricts the relative positions of the backrest component 220 and the seat component 210 and a released state that allows the two to move relative to each other.

[0042] The seat 200 is connected to the first side frame 131 through the side baffle assembly 230. Most of the main body of the seat 200 is located within the accommodation space 120, and the accommodation space 120 can accommodate multiple seats 200. The multiple seats 200 can be arranged in the same orientation or different orientations. The seat assembly 210 of the seat 200 is interconnected with the side baffle assembly 230 to provide a seating surface. The backrest assembly 220 is hinged to the seat assembly 210, and the adjustment of the seating space is achieved through the movement of the backrest assembly 220. By changing the state of the adjustment assembly 300, the spatial position of the backrest assembly 220 can be controlled. Generally speaking, the technical solution disclosed in this application optimizes the cooperation relationship of the various components of the seat 200 and sets the adjustment assembly 300, enabling the backrest assembly 220 of the seat 200 to adjust its position relative to the seat assembly 210, thus improving the user experience.

[0043] The adjustment assembly 300 has various setting methods.

[0044] See the attached Figure 2 In the first embodiment shown, the adjustment assembly 300 includes a flexible restraint strap 310. The restraint strap 310 includes a movable end and a fixed end. The movable end is detachably connected to one of the backrest assembly 220 and the side enclosure assembly 130, and the fixed end is connected to the other; when both ends of the restraint strap 310 are connected to the corresponding components, the adjustment assembly 300 is in a locked state. In the figure, the side enclosure assembly 130 includes an upper edge rod 133 for cooperating with the connecting member 240, and the restraint strap 310 cooperates with the upper edge rod 133. When the restraint strap 310 remains connected, the relative positions of the backrest assembly 220 and the side enclosure assembly 130 are determined. Correspondingly, multiple mating positions can be provided on the backrest assembly 220 and the side enclosure assembly 130 for the restraint strap 310 to cooperate to achieve multi-position adjustment of the backrest assembly 220. Both the movable end and the fixed end can be set to be detachably connected to the corresponding components. When neither end of the restraint strap 310 is connected to the corresponding component, the restraint strap 310 can be separately stored.

[0045] See the attached Figure 3 In the embodiment shown, the adjustment assembly 300 includes a positionable telescopic member 320. The two ends of the telescopic member 320 are respectively connected to the backrest assembly 220 and the side baffle assembly 230. When the telescopic member 320 remains positioned, the adjustment assembly 300 is in a locked state. In the figure, the telescopic rod is multiple nested rods, and the axial length is adjusted by the relative sliding between the rods. Elastic members for restricting the axial relative position are provided between the rods to achieve locking or unlocking. The telescopic rod can also be set as a hinged folding rod, and the length between the two ends of the telescopic rod is changed by the relative angular change between the folding rods. A locking structure for restricting the relative angle is provided between the folding rods to achieve locking or unlocking. The locking structure can be implemented in combination with the prior art.

[0046] See the attachedFigure 4 In the illustrated embodiment, the adjustment assembly 300 includes a lockable hinge shaft 330. The backrest assembly 220 and the seat assembly 210 are connected by the hinge shaft 330. When the hinge shaft 330 is locked, the adjustment assembly 300 is in a locked state. When the hinge shaft 330 is in the locked state, the positions of the backrest assembly 220 and the seat assembly 210 are determined relative to each other. When the hinge shaft 330 is in the unlocked state, the backrest assembly 220 can swing relative to the seat assembly 210 about the axis of the hinge shaft 330. The locking structure of the hinge shaft 330 can be implemented in combination with the prior art.

[0047] See the appendix Figure 5 In the illustrated embodiment, the adjustment assembly 300 includes a flexible restraint strap 310. The restraint strap 310 includes a movable end and a fixed end. The movable end is detachably connected to one of the backrest assembly 220 and the side guard assembly 230, and the fixed end is connected to the other. When both ends of the restraint strap 310 are connected to the corresponding components, the adjustment assembly 300 is in a locked state. Correspondingly, a plurality of mating positions can be provided on the backrest assembly 220 and the side surround assembly 130 for the restraint strap 310 to cooperate to achieve multi-position adjustment of the backrest assembly 220. Both the movable end and the fixed end can be set to be detachably connected to the corresponding components. When neither end of the restraint strap 310 is connected to the corresponding component, the restraint strap 310 can be stored separately.

[0048] The various different forms and different mating position embodiments of the adjustment assembly 300 described above can also be implemented in cooperation with each other. For example, multiple methods can be implemented simultaneously. For another example, different implementation methods can be used on different sides of the seat 200. For yet another example, the features in different implementation methods can be split and combined for implementation.

[0049] In addition, the setting of the adjustment assembly 300 also has certain commonalities. For example, in each embodiment, the adjustment assembly 300 is adjacent to the hinge between the backrest assembly 220 and the seat assembly 210 to provide a larger movement space for the backrest assembly 220 with a smaller dimensional change. The adjustment assembly 300 has multiple locking positions, and the adjustment assembly 300 can enter the locked state at different locking positions. See Figure 5 , a redundant portion 270 is connected between the side guard assembly 230 and the backrest assembly 220. The redundant portion 270 adapts to the distance change between the seat assembly 210 and the backrest assembly 220 through its own deformation. The redundant portion 270 can connect the side guard assembly 230 and the backrest assembly 220 while adapting to the position change of the backrest assembly 220, avoiding gaps. The redundant portion 270 can be provided by the flexible fabric of the seat 200 or by a separate component.

[0050] To provide a more comfortable riding experience, in one embodiment, the seat 200 further includes a seat cover (not shown), which covers at least the seat assembly 210 and the backrest assembly 220. The components that cooperate with the adjustment assembly 300 are located within the seat cover, and the adjustment assembly 300 penetrates the seat cover and cooperates with the seat assembly 210 and / or the backrest assembly 220. Alternatively, the adjustment assembly 300 is disposed within the seat cover to provide a more regular appearance, prevent the adjustment assembly 300 from being affected by the external environment, and prevent the formation of a gap that can pinch your hand.

[0051] For details on the coordination between the seat 200 and the stroller body, see the attached Figure 1 In the illustrated embodiment, the side panel assembly 130 clears the backrest assembly 220. During movement relative to the seat assembly 210, at least a portion of the backrest assembly 220 extends beyond the accommodating space 120. The side panel assembly 130 includes a second side frame 132 connected between two first side frames 131. The second side frame 132 clears the backrest assembly 220. The second side frame 132 is U-shaped, with the ends of the U-shaped opening connected to the two first side frames 131, respectively. The interior of the U-shaped opening is designed to clear the backrest assembly 220.

[0052] For details on how to connect the seat 200 to the stroller body, see Figures 6 to 9 As shown, the first side frame 131 is provided with a connecting seat 250 that engages with the connecting member 240. This enables the seat 200 to be detachably connected to the stroller body. The engaging connection facilitates disassembly and installation operations.

[0053] The connection between the seat 200 and the connector 240 can be achieved through the side guard assembly 230 or a flexible portion fixed to the side guard assembly 230. For example, a webbing 260 connected to the connector 240 is sewn onto the surface of the side guard assembly 230. In the figure, the webbing 260 is arranged in two pieces, one above the other, and passes through the connector 240 respectively.

[0054] The connection between the connector 250 and the stroller body can be provided by providing a mounting location via the first side frame 131. The first side frame 131 includes an upper rod 133, onto which the connector 250 is mounted, enhancing the connection strength between the connector 250 and the stroller body. In other embodiments, the connector 250 can also be fixedly mounted to the upper rod 133. The side guard assembly 230 is provided with two connectors 240 along a first direction, enhancing the stability of the connection between the seat 200 and the stroller body.

[0055] In one embodiment, the connection mode between the connecting member 240 and the joint seat is downward engagement in the direction of gravity, that is, the same as the force direction of the seat 200 after a child sits on it. One of the connecting member 240 and the connecting seat 250 is provided with a locking block 241, and the other is provided with a slot 251 that cooperates with the locking block 241. During installation, the locking block 241 finally abuts against the bottom of the slot 251. A partial portion of the locking block 241 forms a snap 242. The snap 242 can be seen Figure 8 with both ends connected to the locking block 241 as shown, or can be seen Figure 9 with one end connected to the locking block 241 as shown. The inner wall of the slot 251 is provided with a snap groove 252. During installation, the snap 242 is deformed by the connecting seat 250 and finally cooperates with the snap groove 252, and the snap 242 restricts the locking block 241 from disengaging from the slot 251; during disassembly, the cooperation between the snap 242 and the snap groove 252 is released, and the seat 200 module is lifted upward.

[0056] The ways to release the cooperation between the snap 242 and the snap groove 252 are as follows:

[0057] Driving the snap 242 to withdraw from the snap groove 252 by a corresponding unlocking member; or

[0058] As can be seen Figure 9 shown, the snap 242 has a guiding portion 243 that guides it into or out of the snap groove 252. The guiding portion 243 is an arc surface, and lifting the seat 200 drives the snap 242 to deform and withdraw from the snap groove 252. The guiding portion 243 can be provided only on the lower surface of the snap 242, or only on the upper surface of the snap 242, or can be provided on both the upper surface and the lower surface of the snap 242.

[0059] The technical solution disclosed in this application can conveniently set or remove the seat on the stroller by optimizing the cooperation relationship of the components of the seat; at the same time, an adjusting component is provided to enable the backrest component of the seat to adjust its position relative to the seat component, improving the use experience.

[0060] 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 there is no contradiction in the combination of these technical features, it should be considered as the scope recorded 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 respective embodiments involved at the same time.

[0061] The above-described embodiments only represent several implementation manners of this application, and their descriptions are relatively specific and detailed, but 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 this application, several deformations and improvements can still be made, and these all belong to the protection scope of this application.
