When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.
[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0035] Child vehicles generally include a mobile frame 100 and a seat 200 mounted on the frame 100. The seat 200 may be provided as part of the frame 100 or may be a separate component. The seat 200 may be fixed to the frame 100 or may be detachably mounted to the frame 100. To improve the riding space, comfort, and adaptability of child vehicles, [further details are needed]. Figure 1 To be continued Figure 2 As shown, this application discloses a child vehicle that can accommodate multiple passengers, including a frame 100 and a seat 200.
[0036] Specifically, the frame 100 has a forward / rear direction 910 and a corresponding left / right direction 920 that move under traction or pushing. The frame 100 includes a base frame 110 for supporting the accommodating space, a front frame 120 and a rear frame 130 located on either side of the forward / rear direction 910, and side frames 140 located on either side of the left / right direction 920. The frame 100 also includes a running gear, such as rollers or sliding components, for engaging with a support surface. The base frame 110, front frame 120, rear frame 130, and side frames 140 of the frame 100 have a defined positional relationship during use; that is, they can be understood as a frame structure with a specific shape, and the running gear has a defined constraint relationship with this frame structure. For details, please refer to the appendix. Figure 1 As shown, the traveling mechanism includes rollers and wheel seats for mounting the rollers, with the wheel seats connected to the base frame 110. In other embodiments, the wheel seats may also be connected to any one or more of the front frame 120, rear frame 130, and side frame 140.
[0037] In this embodiment, there are one or more seats 200. Each seat 200 includes a seat surface 210, a backrest 220, and a footrest 230. The backrest 220 is connected to the side frame 140 on the corresponding side and extends toward the base frame 110. The seat surface 210 extends in the front-rear direction 910 and is supported by the base frame 110. The base frame 110 is provided with an open window 111, and the footrest 230 extends below the base frame 110 through the open window 111. The footrest 230 provides a footrest 231 for accommodating the occupant's feet. The shape of the footrest 231 can be maintained by the rigid footrest 230, that is, the footrest 230 can maintain its own posture. The shape of the footrest 231 can also be maintained by the flexible footrest 230 and the frame 100 working together. For example, the footrest 230 is a flexible fabric connected to the frame 100. When the rider's foot applies force to the footrest 230, the flexible fabric provides support through its connection with the frame 100. Overall, the seat 200 can be a one-piece structure or a split structure. The various parts of the seat 200 can be configured to be connected and movable relative to each other, or they can be configured to move independently without interference. For example, in one embodiment, the various parts of the seat 200 are made of flexible material, and are partially filled with rigid support plates to improve mechanical properties. The support plates can be made of metal and / or polymer and / or wood.
[0038] In this embodiment, by setting an extended seat 200 on the frame 100 in the front-to-back direction 910, the seating space is effectively expanded. The extended space of the footrest 230 provided by the open window 111 improves the riding comfort. The trailer-structured frame 100 can flexibly install or remove the seat 200 according to the scenario, and has the advantages of large seating space, good comfort and good adaptability.
[0039] For details regarding the settings of seat 200, please refer to the appendix. Figure 2 and attached Figure 3 As shown, there are two seats 200 arranged opposite each other, with an open window 111 located in the middle of the base frame 110. The two seats 200 share a footrest 230. The top of the backrest 220 extends to the top of the side frame 140. The backrest 220 can be constrained by connecting its top to the top of the side frame 140, or it can be connected to the side frame 140 by a separate mounting component. The specific structure of the mounting component can be implemented in conjunction with existing technology. The base frame 110 defines a support plane 112, and the seat surface 210 abuts against the support plane 112 for support. The two opposing seats 200 are an interconnected integral structure, which can be installed onto the frame 100 as a whole or removed from the frame 100. In other embodiments, the two opposing seats 200 can also be separate structures for independent removal.
[0040] For detailed specifications of the frame 100, please refer to the appendix. Figure 1 To be continued Figure 5As shown, the frame 100 has an unfolded state that provides accommodating space (e.g., with attached...). Figure 1 (as shown) and the relative folded state (e.g., attached) Figure 5 As shown in the diagram, in the folded state, the front frame 120, rear frame 130, and each side frame 140 are close to the base frame 110. In the unfolded state, the base frame 110 defines a supporting plane 112, and the front frame 120, rear frame 130, and each side frame 140 are perpendicular to the supporting plane 112 and provide accommodating space. (See attached diagram) Figure 5 In the folded state, each side frame 140 is close to the top surface of the base frame 110, and the front frame 120 and the rear frame 130 are close to the top surface of the side frames 140 to provide a neat folded appearance for easy storage and transportation.
[0041] Furthermore, the bottom of each side frame 140 is connected to the base frame 110 via side hinges 141. When the frame 100 is in the unfolded state, at least a portion of each side frame 140 is located on the outside of the base frame 110. This arrangement provides a more spacious interior while maintaining the same folded volume of the frame 100. Similarly, when the frame 100 is in the unfolded state, the front frame 120 and rear frame 130 can also be configured to have at least a portion located on the outside of the base frame 110. Furthermore, when the frame 100 is in the unfolded state, in the projection of gravity, the front frame 120 and rear frame 130 are located on the outside of the side edges of the base frame 110.
[0042] To avoid interference between components, the side hinge 141 defines a first axis of rotation, which is close to the support plane 112. For example, the distance between the first axis of rotation and the support plane 112 is such that the side frame 140 can be completely against the base frame 110 when folded. The bottom of the front frame 120 is connected to the base frame 110 via the front hinge 121. The front frame 120 is located above the base frame 110. The front hinge 121 defines a second axis of rotation, which is farther from the support plane 112 than the first axis of rotation. For example, the distance between the second axis of rotation and the support plane 112 is such that the front frame 120 can be completely against the side frame 140 when folded. The bottom of the rear frame 130 is connected to the base frame 110 via a rear hinge 131. The rear frame 130 is located above the base frame 110. The rear hinge 131 defines a third axis of rotation, which is farther away from the support plane 112 than the first axis of rotation. For example, the distance between the third axis of rotation and the support plane 112 is such that the rear frame 130 can completely rest against the side frame 140 after being folded. (See attached diagram.) Figure 5As shown, the positional relationship of the first, second, and third rotation axes allows the rear frame 130 and front frame 120 to be positioned above the frame 100 when it is folded, thus allowing auxiliary structures (such as the sliding door 132 and push handle 122 mentioned below) to be installed on opposite sides of the front frame 120 and rear frame 130. To further improve the appearance of the folded frame 100, the second and third rotation axes are arranged in parallel. Preferably, the second and third rotation axes are at the same height relative to the supporting plane 112.
[0043] The changing state of the frame 100 requires corresponding positioning structures to ensure its stability in a specific state. For example, a locking mechanism can be installed between any two relatively moving parts of the frame 100. (See attached document) Figure 1 In this design, the locking mechanism includes a locking element 142 and a control element 143. Specifically, the side frame 140 is equipped with a locking element 142 that cooperates with the front frame 120 and the rear frame 130, respectively, and a control element 143 that drives the locking element 142 into or out of the locked state. The specific structure of the locking element 142 and the linkage relationship between the locking element 142 and the control element 143 can be implemented using existing technology.
[0044] The front frame 120 and rear frame 130 mentioned above are only relative concepts in the front-rear direction 910 of the frame 100, and should be understood as the first frame and the second frame. The front frame 120 and rear frame 130 can be set uniformly, or you can refer to the appendix. Figure 1 As shown, the front frame 120 and the rear frame 130 are configured differently. One of the front frame 120 and the rear frame 130 is equipped with a push handle 122, and the other is equipped with a movable door 132. The movable door 132 has a closed position that encloses the accommodating space in the front-to-back direction 910 and an open position. The opening and closing of the movable door 132 can be referred to the attached diagram. Figure 3 As shown. The movable door 132 is hinged to the front frame 120 or the rear frame 130 on one side in the left-right direction 920, and the movable door 132 moves relative to the front frame 120 or the rear frame 130. (See attached diagram) Figure 5 As shown, the movable door 132 is mounted on the rear frame 130. When the frame is folded down, the rear frame 130 is positioned between the movable door 132 and the base frame 110. In this embodiment, the push handle 122 is mounted on the front frame 120, and the movable door 132 is mounted on the rear frame 130. A door lock 133 is provided between the movable door 132 and the rear frame 130 to lock their positional relationship. The specific structure of the door lock 133 can be implemented using existing technology.
[0045] To balance the driving experience of the frame 100 with its folding performance, the push lever 122 has a folding position close to the front frame 120 and a working position away from the front frame 120. (See attached...) Figure 5As shown, in the folded state, the front frame 120 is positioned between the push handle 122 and the base frame 110. Further, the front frame 120 includes a main body and a telescopic rod 123 movably mounted to the main body in the height direction. The push handle 122 is hinged to the top of the telescopic rod 123. A telescopic locking mechanism is provided between the telescopic rod 123 and the main body, and a rotation locking mechanism is provided between the push handle 122 and the telescopic rod 123. The telescopic locking mechanism and the rotation locking mechanism can be linked and controlled. The specific structures of the telescopic locking mechanism and the rotation locking mechanism can be implemented using existing technology.
[0046] The shape change of the frame 100 can be linked with the seat 200 to simplify the folding operation. For example, in one embodiment, the backrest 220 and the seat 210 are hinged to each other. The backrest 220 moves relative to the side frame 140. That is, the side frame 140 can move itself while the backrest 220 and the seat 210 are close together, so as to realize the synchronization of the state change of the frame 100 and the state change of the seat 200.
[0047] The following is in conjunction with the appendix Figure 4 and attached Figure 5 The illustrated embodiment demonstrates the folding process of a child vehicle:
[0048] The locking mechanism is released to allow relative movement of the various components of the frame 100;
[0049] Drive the push rod 122 toward the front frame 120 and retract the telescopic rod 123;
[0050] The tops of the two side frames 140 are driven to move closer together so that the side frames 140 move closer to the base frame 110;
[0051] During the closing process, the backrest 220 of the seat 200 moves closer to the seat surface 210 simultaneously;
[0052] The tops of the front frame 120 and the rear frame 130 are driven to move closer to each other so that the front frame 120 moves closer to the folded side frame 140 from the front and the rear frame 130 moves closer to the folded side frame 140 from the rear.
[0053] During the closing process, the front frame 120 pushes the handle 122 to close to the side frame 140, and during the closing process, the rear frame 130 moves the door 132 to close to the side frame 140.
[0054] When folded, the frame 100 has a multi-layered plate structure that fits snugly against the base plate. It has a neat appearance and is easy to store and transport. When it is necessary to further control the folded volume, the running mechanism can be set to a foldable or detachable structure.
[0055] The deployment process for child vehicles is the reverse of the steps described above, and will not be repeated here.
[0056] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.
[0057] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
