Embodiments of the present invention

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. The components of the embodiments of this disclosure described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of this disclosure provided in the accompanying drawings is not intended to limit the scope of the claimed disclosure, but merely to illustrate selected embodiments of the disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0044] In the description of this disclosure, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure.

Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0047] As described in the background section, existing outdoor folding strollers with attached seats typically design the seat as a separate accessory. When folding and storing, the seat is usually disassembled and separated from the stroller body, then stored separately, while the stroller body is folded flat or bundled together. However, this method of separating the seat from the stroller body after folding is not only cumbersome but also increases the overall packaging size, making it inconvenient to carry and resulting in a poor user experience.

[0048] Based on this, please refer to Figures 1-7. The embodiments of this disclosure provide a folding trolley 100, which effectively improves the aforementioned technical problems. Specifically, when folded for storage, the seat 20 can be folded along with the trolley body 10 without disassembling the seat 20. Operation is simple, and the folded size does not affect the overall packaging volume, making it convenient to use and carry. The folding trolley 100 will be described in detail below.

[0049] Please refer to Figures 1 and 2. Figure 1 is a schematic diagram of the folding trolley 100 provided in this embodiment after unfolding, and Figure 2 is a schematic diagram of the folding trolley 100 provided in this embodiment after folding. Referring to Figures 1 and 2, the folding trolley 100 includes a body 10 and a seat 20. The body 10 includes a first folding frame 11 and a second folding frame 12, which are rotatably connected. Both the first folding frame 11 and the second folding frame 12 can be folded or unfolded; and when the first folding frame 11 and the second folding frame 12 are unfolded, there is an installation space 13 between them. The seat 20 includes at least a first folding seat 21, which is detachably connected to the first folding frame 11. The first folding seat 21 is located within the installation space 13, and is configured to fold or unfold along with the first folding frame 11.

[0050] As is easily understood, the first folding frame 11 and the second folding frame 12 can be folded together by rotating and moving closer together, or unfolded by moving further apart. Since the first folding seat 21 has a folding function, it can be detachably connected to the first folding frame 11 after the vehicle body 10 is unfolded, and is located in the installation space 13. Thus, it can be folded together with the folding of the vehicle body 10, or unfolded with the unfolding of the vehicle body 10. The whole process does not require disassembling the seat 20, the operation is simple, and the overall packaging volume is not affected after folding, making it convenient to use and carry.

[0051] To further meet the user's needs, in this embodiment, the stool 20 also includes a second folding stool 22. The second folding stool 22 is detachably connected to the second folding frame 12. The second folding stool 22 is located in the installation space 13 and is arranged opposite to or in the same direction as the first folding stool 21. The second folding stool 22 is configured to fold or unfold with the second folding frame 12.

[0052] In other words, the second folding seat 22 can also be folded up along with the second folding frame 12, or unfolded along with the second folding frame 12. Thus, the first folding seat 21 and the second folding seat 22 do not need to be disassembled when in use or storage. While further increasing the seat function, it will not affect the overall packaging volume of the stroller, making it convenient to use and carry.

[0053] Please refer to Figure 3, which is a structural schematic diagram of the stool 20 provided in this embodiment. In conjunction with Figures 1-3, specifically, the first folding stool 21 includes a first backrest 211 and a first seat 212. The first backrest 211 is rotatably connected to the first seat 212, and the first backrest 211 is detachably connected to the first folding frame 11.

[0054] Similarly, the second folding seat 22 includes a second backrest 221 and a second seat 222, the second backrest 221 being rotatably connected to the second seat 222 and the second backrest 221 being detachably connected to the second folding frame 12.

[0055] Furthermore, in order to improve user comfort and enhance the installation stability of the seat 20, in this embodiment, the first folding seat 21 further includes a first soft surface panel 213 and a second soft surface panel 214. The first soft surface panel 213 and the second soft surface panel 214 are arranged opposite to each other and are both connected to the first backrest panel 211 and the first seat panel 212. The first soft surface panel 213 and the second soft surface panel 214 can be detachably connected to the first folding frame 11.

[0056] Similarly, the second folding seat 22 also includes a third soft cover 223 and a fourth soft cover 224. The third soft cover 223 and the fourth soft cover 224 are arranged opposite to each other and are both connected to the second backrest 221 and the second seat 222. The third soft cover 223 and the fourth soft cover 224 can be detachably connected to the second folding frame 12.

[0057] It should be noted that when the first folding stool 21 is unfolded, there is a seating space between the first backrest 211, the first seat 212, the first soft cover 213 and the second soft cover 214. Since the first soft cover 213 and the second soft cover 214 are both made of soft material, both can be folded into the seating space.

[0058] Specifically, please refer to Figure 4, which is a schematic diagram of the unfolding and folding of the first folding seat 21 provided in this embodiment. In conjunction with Figures 3 and 4, when the first folding seat 21 is folded, the first soft cover 213 and the second soft cover 214 can be folded first and pulled into the seat space. Then, the first seat plate 212 rotates relative to the first backrest 211 under the folding action of the first folding frame 11, thereby pressing the first soft cover 213 and the second soft cover 214 between the first backrest 211 and the first seat plate 212 to complete the folding and storage.

[0059] Similarly, when the second folding stool 22 is unfolded, there is also a seating space between the second backrest 221, the second seat 222, the third soft backrest 223, and the fourth soft backrest 224. Since the third soft backrest 223 and the fourth soft backrest 224 are both made of soft material, both can be folded into this seating space. The specific folding method of the second folding stool 22 can be referred to the folding method of the first folding stool 21 shown in Figure 4, and will not be described in detail here.

[0060] It should be noted that in this embodiment, the first backrest panel 211, the first seat panel 212, the second backrest panel 221, and the second seat panel 222 are all hard plastic panels covered with soft material. They are connected to the corresponding first soft protective panel 213, second soft protective panel 214, third soft protective panel 223, and fourth soft protective panel 224 by sewing, so as to facilitate folding and folding.

[0061] Further, please refer to Figures 5 and 6. Figure 5 is a schematic diagram of the vehicle body 10 after unfolding according to this embodiment, and Figure 6 is a schematic diagram of the vehicle body 10 during the folding process according to this embodiment. In conjunction with Figures 3-6, the first folding frame 11 includes a first support frame 111, a first base frame 112, a first cross frame 113, and a second cross frame 114. The first support frame 111 is detachably connected to the first backrest panel 211, and the first base frame 112 is rotatably connected to the first support frame 111. The first cross frame 113 and the second cross frame 114 are respectively disposed on opposite sides of the first support frame 111, and are detachably connected to the first soft surface panel 213 and the second soft surface panel 214, respectively.

[0062] The second folding frame 12 includes a second support frame 121, a second base frame 122, a third cross frame 123, and a fourth cross frame 124. The second support frame 121 is detachably connected to the second backrest panel 221, and the second base frame 122 is rotatably connected to the second support frame 121. The third cross frame 123 and the fourth cross frame 124 are respectively disposed on opposite sides of the second support frame 121 and are detachably connected to the third soft-surface panel 223 and the fourth soft-surface panel 224, respectively. The first base frame 112 is rotatably connected to the second base frame 122, the first cross frame 113 is rotatably connected to the third cross frame 123, and the second cross frame 114 is rotatably connected to the fourth cross frame 124.

[0063] Understandably, the first folding frame 11 can be folded or unfolded through the rotational engagement of the first base frame 112 and the first support frame 111, coupled with the cross-structure of the first cross frame 113 and the second cross frame 114. Similarly, the second folding frame 12 can be folded or unfolded through the rotational engagement of the second base frame 122 and the second support frame 121, coupled with the cross-structure of the third cross frame 123 and the fourth cross frame 124. Thus, the entire vehicle body 10 can be folded up through the rotational engagement of the first base frame 112 and the second base frame 122, the rotational engagement of the first cross frame 113 and the third cross frame 123, and the rotational engagement of the second cross frame 114 and the fourth cross frame 124.

[0064] It should be noted that, in some embodiments, the first cross frame 113 and the second cross frame 114 can be slidably disposed on opposite sides of the first support frame 111, and similarly, the third cross frame 123 and the fourth cross frame 124 can also be slidably disposed on opposite sides of the second support frame 121. This facilitates the folding and unfolding of the first folding frame 11 and the second folding frame 12, improving user comfort.

[0065] Furthermore, by detachably connecting the first backrest panel 211, the first soft surface panel 213, and the second soft surface panel 214 to the first support frame 111, the first cross frame 113, and the second cross frame 114 respectively, and by detachably connecting the second backrest panel 221, the third soft surface panel 223, and the fourth soft surface panel 224 to the second support frame 121, the third cross frame 123, and the fourth cross frame 124 respectively; and by allowing the first base frame 112 to rotate the first seat plate 212 and the second base frame 122 to rotate the second seat plate 222, the first folding seat 21 and the second folding seat 22 can fold and unfold along with the folding of the vehicle body 10. Moreover, the first folding seat 21 and the second folding seat 22 can be fixed in three directions, improving installation stability.

[0066] Referring to Figures 1 and 3, the folding trolley 100 also includes a first fixing buckle 31 and a second fixing buckle 32. The first fixing buckle 31 is disposed on the first backrest 211 and is engaged with the first support frame 111; the second fixing buckle 32 is disposed on the second backrest 221 and is engaged with the second support frame 121.

[0067] In this embodiment, the first fixing buckle 31 and the second fixing buckle 32 are both connected to the soft surface of the first backrest plate 211 and the second backrest plate 221 by means of the woven strip on them, respectively, to achieve fixation.

[0068] It should be noted that in this embodiment, the first fixing buckle 31 and the second fixing buckle 32 are specifically engaged with the connecting rods of the first support frame 111 and the second support frame 121, respectively. Of course, in other embodiments, the detachable method of the backrest panel and the support frame is not limited to this; they can also be connected by means of pins, buckles, or magnetic connections.

[0069] Additionally, it should be noted that in this embodiment, there are two of both the first fixing buckle 31 and the second fixing buckle 32. Of course, in other embodiments, the number of the first fixing buckle 31 and the second fixing buckle 32 may be one, three, or four, etc.

[0070] To further improve the connection stability between the first backrest panel 211 and the second backrest panel 221 and the first support frame 111 and the second support frame 121 respectively, the folding trolley 100 also includes a first buckle 41 and a second buckle 42. The first backrest panel 211 and the second backrest panel 221 are both provided with the first buckle 41, and the first support frame 111 and the second support frame 121 are both provided with the second buckle 42. The first buckle 41 and the second buckle 42 are engaged.

[0071] As shown in Figure 1, one of the first buckle 41 and the second buckle 42 is a female buckle, and the other is a female connector, thus achieving a detachable connection. Of course, in other embodiments, the detachable connection method is not limited to this; the two can also be connected by means of pins, snaps, or magnetic connections.

[0072] Referring to Figures 1, 3, and 5, in this embodiment, the folding trolley 100 further includes a third buckle 43 and a fourth buckle 44. The first soft surface guard plate 213 and the second soft surface guard plate 214 are both provided with the third buckle 43, and the first cross frame 113 and the second cross frame 114 are both provided with the fourth buckle 44. The third buckle 43 and the fourth buckle 44 are engaged in a plug-in cooperation.

[0073] In other words, the connection between the first soft-surface guard plate 213 and the second soft-surface guard plate 214 and the first cross frame 113 and the second cross frame 114, respectively, is also achieved through a snap-fit ​​method. Of course, in other embodiments, the detachable connection method is not limited to this; the connection can also be achieved through pins, snaps, or magnetic connections.

[0074] Furthermore, the folding trolley 100 also includes a fifth buckle 45 and a sixth buckle 46. The third soft surface guard plate 223 and the fourth soft surface guard plate 224 are both provided with the fifth buckle 45, and the third cross frame 123 and the fourth cross frame 124 are both provided with the sixth buckle 46. The fifth buckle 45 and the sixth buckle 46 are engaged in a plug-in cooperation.

[0075] Similarly, the connection between the third soft-surface guard plate 223 and the fourth soft-surface guard plate 224 and the third cross bracket 123 and the fourth cross bracket 124, respectively, is also achieved through a snap-fit ​​method. Of course, in other embodiments, the detachable connection method is not limited to this; the connection can also be achieved through pins, snaps, or magnetic connections.

[0076] Please refer to Figures 5 and 6. In order to facilitate the user's folding operation, the folding trolley 100 can be folded and stored or unfolded as a whole. In this embodiment, the folding trolley 100 also includes a folding component 50, which is disposed at the connection between the first base frame 112 and the second base frame 122.

[0077] In other words, when the trolley needs to be folded up, simply pull the folding component 50 upwards, which will cause the first base frame 112 and the second base frame 122 to rotate relative to each other, and then cause the corresponding cross frame to slide and rotate relative to each other, thereby achieving folding. The overall operation is convenient and quick, improving folding efficiency.

[0078] It should be noted that in this embodiment, the folding component 50 is specifically a folding webbing, which has a certain degree of elasticity to ensure user comfort. Of course, in other embodiments, the folding component 50 can also be made of other materials or have other structures.

[0079] Please refer to Figure 7, which is a schematic diagram of the folded vehicle body 10 provided in this embodiment. In conjunction with Figure 7, in order to improve the stability of the folded vehicle body 10 and prevent it from unfolding during transfer, the folding trolley 100 also includes a first locking member 60. The first locking member 60 is fixedly connected to one of the first cross frame 113 and the third cross frame 123, and the first locking member 60 is configured to be detachably connected to the other of the first cross frame 113 and the third cross frame 123.

[0080] Specifically, in this embodiment, the first locking member 60 is fixedly connected to the third cross frame 123. When the vehicle body 10 is folded, the first locking member 60 is connected to the first cross frame 113, thereby further locking and fixing the first cross frame 113 and the third cross frame 123. Of course, in other embodiments, the first locking member 60 can also be fixedly connected to the first cross frame 113 and then connected and fixed to the third cross frame 123 after folding.

[0081] It should be noted that in some other embodiments, the two cross frames on the other side of the vehicle body 10 can also be locked and fixed. For example, in other embodiments, the folding trolley 100 also includes a second locking member, which is fixedly connected to one of the second cross frame 114 and the fourth cross frame 124, and the second locking member is configured to be detachably connected to the other of the second cross frame 114 and the fourth cross frame 124.

[0082] Referring to Figure 7, specifically, the first locking member 60 is provided with a first groove 61, and one of the first cross bracket 113 and the third cross bracket 123 is provided with a first protrusion 1131.
