[0059] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0060] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between. 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.

[0061] 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.

[0062] In this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0063] See Figure 1 ~Picture Figure 9 One embodiment of this application provides a foldable vehicle support having opposing front and rear sides, with the length direction L defined from the front to the rear side (see [reference]). Figure 3 ), Figure 3 The left side is the front and the right side is the rear, but this is only for ease of description and understanding, and does not limit the direction of movement or the user's orientation during use. During normal use, it also has a corresponding height direction H (see reference). Figure 1 ).

[0064] The vehicle support frame includes a top component 100 and a bottom component 200 arranged opposite to each other, and a support component 400 connecting the top component 100 and the bottom component 200. Along the height direction, the top component 100 is positioned above the bottom component 200, and the support component 400 forms an accommodating space. When this vehicle support frame is used to assemble a foldable vehicle, a wheel assembly 300 can also be configured at the bottom of the vehicle support frame. As shown in the figure, this includes a first wheel 310 at the front and a second wheel 320 at the rear. The wheel assembly 300 can be installed on either the bottom component 200 or the support component 400. In the embodiment shown, the wheel assembly 300 is specifically installed on the bottom component 200.

[0065] The vehicle support has a relatively deployed state. Figure 1 ) and folded state ( Figure 3 Unless otherwise specified, the positional relationships and spatial orientation of the components in this application can be understood as in the unfolded state. The viewpoint in the figure is along the length of the support structure. Due to the limited viewpoint, it can be understood that the same structure exists on the other side of the length direction, and the corresponding components on both sides can be connected to each other through connectors (such as rods or brackets) to ensure strength and to limit the accommodating space. Flexible pockets, trays, seats, etc. can be installed in the accommodating space, preferably in a way that facilitates folding with the vehicle support.

[0066] To facilitate folding, the support assembly 400 adopts a deformable structure and is hinged to the top assembly 100 and the bottom assembly 200 respectively, so that during the state switching process, the top assembly 100 is raised and lowered relative to the bottom assembly 200 and stacked on top of the bottom assembly 200 in the folded state.

[0067] This application describes the hinge to illustrate the movable connection between two components. Structurally, conventional pivots, hinges, etc., can be used. To maintain the unfolded state, a locking mechanism can be provided at at least one hinge, with a corresponding linked unlocking mechanism. Alternatively, the locking component can directly act on adjacent components. Using a hinge reduces the resistance when the support component 400 unfolds or folds, thus improving the feel.

[0068] The support assembly 400 includes a first unit and a second unit arranged opposite to each other in the front-rear direction;

[0069] Each unit includes two hinged connectors. The two connectors in the same unit adopt a two-fold structure to adapt to the state switching of the support component 400. Each unit is hinged between the top component 100 and the bottom component 200. One connector of one unit is also hinged to a connector of another unit.

[0070] Furthermore, the two connectors in the same unit include an upper connector hinged to the top assembly 100 and a lower connector hinged to the bottom assembly 200; the upper connector of one unit is hinged to the lower connector of the other unit.

[0071] The support component 400 includes:

[0072] The first connector 410 is hinged to the top assembly 100, and the first connector 410 also provides two non-overlapping connection positions;

[0073] The second connector 420 is hinged at one end to the bottom component 200 and at the other end to the first connection position;

[0074] The third connector 430 is hinged at one end to the bottom component 200 and at the other end to the second connector.

[0075] The fourth connector 440 is hinged at one end to the top assembly 100 and at the other end to the second connector 420. (Example) Figure 2 As shown, in this embodiment, the first connector 410 also has a support rod 411, one end of which is the first connection position.

[0076] Correspondingly, the upper connector in the first unit is the fourth connector 440, and the lower connector is the second connector 420. The upper connector in the second unit is the first connector 410, and the lower connector is the third connector 430, wherein the second connector 420 is hinged to the first connector 410.

[0077] The vehicle support has a front side and a rear side. During the process of switching the vehicle support to the folded state, the two connecting positions swing with the first connecting member 410 and both move from the front side to the rear side.

[0078] Furthermore, one end of the fourth connector 440 is connected to the top assembly 100 via the first hinge point 120, and one end of the first connector 410 is connected to the top assembly 100 via the second hinge point 130, with the first hinge point 120 located in front of the second hinge point 130.

[0079] One end of the second connector 420 is connected to the bottom assembly 200 through the third hinge point 220, and one end of the third connector 430 is connected to the bottom assembly 200 through the fourth hinge point 230, with the third hinge point 220 located in front of the fourth hinge point 230.

[0080] The other end of the fourth connector 440 is connected to the middle of the second connector 420 via the fifth hinge point 460. Preferably, the first hinge point 120 is located behind the third hinge point 220, and the fourth hinge point 230 is located behind the second hinge point 130.

[0081] The two connection positions in the first connector 410 are as follows:

[0082] The sixth hinge point 470, the other end of the third connector 430 is connected to the sixth hinge point 470;

[0083] The seventh hinge point 480, and the other end of the second connector 420 is connected to the seventh hinge point 480;

[0084] The third hinge point 220, the fourth hinge point 230, the sixth hinge point 470, and the seventh hinge point 480 form a deformable quadrilateral. (See reference.) Figure 1 The quadrilateral is formed by the third connector 430, the base 210, the second connector 420, and the dotted line in the figure. The quadrilateral can be regarded as a planar four-bar linkage mechanism. When it is expanded or contracted, the four-bar linkage mechanism deforms accordingly.

[0085] In unfolded state (reference) Figure 1 , Figure 4 and Figure 5 The quadrilateral is a concave quadrilateral, and the sixth hinge point 470 is the concave part of the concave quadrilateral. In at least one position during the state switching process, the quadrilateral is a convex quadrilateral.

[0086] Taking the folding state as an example, the folding direction of the third connector 430 can be referenced. Figures 1-2 Center arrow A indicates that both the seventh hinge point 480 and the sixth hinge point 470 move to the right. As the sixth hinge point 470 moves, it gradually bulges outward, transforming the quadrilateral into a convex quadrilateral. Similarly, this also occurs when the vehicle support is deployed to this state.

[0087] In other embodiments, the seventh hinge point 480 in the folded state is positioned close to or even beyond the third connector 430.

[0088] For example, when the seventh hinge point 480 is located to the left of the third connector 430, the quadrilateral is a concave quadrilateral in the folded state, and the seventh hinge point 480 is a recessed part.

[0089] For example, when the seventh hinge point 480 crosses the third connector 430, it can be referred to Figure 3 In the folded state, the quadrilateral is an inverted quadrilateral, where the second connector 420 and the third connector 430 intersect.

[0090] For example, in the folded state, the line connecting the sixth hinge point 470 and the seventh hinge point 480 is nearly collinear with the third connector 430.

[0091] Preferably, in the folded state, the angle between the line connecting the sixth hinge point 470 and the seventh hinge point 480 and the third connector 430 is less than 30 degrees, for example less than 15 degrees, or less than 5 degrees, until they are collinear. This allows the support assembly 400 to be compressed as much as possible in the height direction when folded, further reducing the storage volume.

[0092] refer to Figure 1 and Figure 4 In the unfolded state, the fifth hinge point 460 and the sixth hinge point 470 are located in the middle of the height direction, and their adjacent parts form a corner.

[0093] The middle part of the vehicle support in the height direction is understood as the central region. For example, this central region accounts for 60% of the total height of the vehicle support, or 50% of the total height of the support structure.

[0094] The length direction is defined from the front to the rear, and the corners formed by the fifth hinge point 460 and the sixth hinge point 470 are opposite each other along the length direction. In this embodiment, the corner height of the sixth hinge point 470 is higher than the height of the fifth hinge point 460.

[0095] refer to Figure 2 and Figure 6 During the folding process, the fifth hinge point 460 and the sixth hinge point 470 both move toward the rear along the length direction.

[0096] refer to Figure 3 and Figure 8 In the folded state, the corners formed by the fifth hinge point 460 and the sixth hinge point 470 both point towards the rear along the length direction.

[0097] To facilitate pushing or dragging, the first connector 410 further extends to form a pusher 450. In the unfolded state, the pusher 450 is located above the top component 100. In the figure, the pusher 450 is located on the right side.

[0098] To accommodate folding and achieve a better folded posture, the first connector 410 and the pusher 450 are approximately collinear and nearly overlap with the top component 100 in the folded state.

[0099] During the folding process, you can refer to Figures 1-2 In the direction of arrow B, the top of the pusher 450 flips forward until it reaches the folded state. To maintain the unfolded posture of the pusher 450, a locking mechanism can be provided. Of course, to further improve the folding efficiency, the locking mechanism of the pusher 450 can be linked with the locking mechanism of the vehicle support.

[0100] The top component 100 and the bottom component 200 are roughly the same length, and are also roughly aligned along the height direction in both the unfolded and folded states, making them more regular when unfolded or folded.

[0101] Preferably, in the folded state, the push handle 450 does not extend beyond both ends of the top component 100 to avoid occupying extra space.

[0102] The first connector 410 is T-shaped or L-shaped and has three ends, corresponding to the second hinge point 130, the sixth hinge point 470, and the seventh hinge point 480, respectively.

[0103] The second hinge point 130, the sixth hinge point 470, and the seventh hinge point 480 are not collinear and are located at the three ends. Preferably, the first connector 410 is T-shaped.

[0104] When the first connector 410 is L-shaped, the two ends of the L-shape are the two ends, and the corner of the L-shape is the third end.

[0105] In this embodiment, each connecting member is a rod. The top component 100 is the top frame 110, and the bottom component 200 is the base 210. The bottom component 200 is used to support items, and the top frame 110 can be equipped with external components such as sunshades and tabletops as needed.

[0106] Using the structures of the preceding embodiments, one embodiment of this application also provides a foldable vehicle, including the vehicle support described above and a wheel assembly 300 connected to the vehicle support.

[0107] 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.

[0108] 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.
