[0608] Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Although the present disclosure is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that the present disclosure is not intended to be limited to the particular embodiments set forth herein, but, on the contrary, covers all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure.

[0609] Hereinafter, the present disclosure will be described in detail with reference to the accompanying drawings.

[0610] When it is necessary to travel with an infant or an animal, a user can use a hand-held carrier to carry and move the infant or the animal. In order to move the hand-held carrier conveniently and labor-savingly, the carrier can be installed on a moving device to move together with the moving device.

[0611] In a first aspect of the present disclosure, a wheeled mobile device 11 with locking function is provided.

[0612] Referring to Figure 1A and Figure 1B , a wheeled mobile device 11 according to an embodiment of the first aspect of the present disclosure is schematically shown. In which, Figure 1A is a perspective view of the wheeled mobile device 11 of the present embodiment, Figure 1B is a top view of the wheeled mobile device 11.

[0613] As Figure 1A shown, the wheeled mobile device 11 of the present embodiment comprises a frame 110, a clamping assembly 120 and a carrier 130. The frame 110 has a structure similar to a trolley, the specific structure of which will be described below. The clamping assembly 120 is mounted on the frame 110 and can be locked and unlocked with an object to be locked (also referred to as "object to be clamped", hereinafter referred to as "object") so that the object is stably placed thereon, thereby improving the safety of the object during movement. Moreover, through the operation of the clamping assembly 120, the user can conveniently mount the object to the frame 110 or dismount it from the frame 110.

[0614] In the present embodiment, as Figure 1A shown, the object can be the carrier 130, which has a box structure for carrying infants or animals (such as pets, etc.), and can be mounted on the frame 110 by the clamping assembly 120.

[0615] In combination with Figure 1B shown, the carrier 130 comprises a handle 1330 and a box body 1340, wherein the handle 1330 is used to lift the carrier 130, and the box body 1340 is used to carry infants or animals. When the carrier 130 is mounted on the clamping assembly 120, the longitudinal center line C11 of the carrier 130 and the longitudinal center line C12 of the clamping assembly 120 are generally in the same vertical plane, i.e., the carrier 130 is generally symmetrically arranged with respect to the longitudinal center line C12 of the clamping assembly 120. It should be noted that the "longitudinal center line" refers to the center line perpendicular to the connecting line of the end of the handle 1330 on the carrier 130, and Figure 1B the direction shown by "D11" (i.e., the longitudinal direction D11) is the longitudinal extension direction parallel to the longitudinal center lines C11 and C12.

[0616] In an embodiment, as Figure 1BAs shown, the lateral center line C13 of the carrier 130 is substantially in the same vertical plane as the lateral center line C14 of the socket assembly 120. At this time, the carrier 130 is substantially centrally placed with respect to the socket assembly 120. It is noted that the "lateral center line" refers to the center line parallel to the connecting line of the two ends of the handle 1330, and Figure 1B The direction indicated by "D12" (i.e., the lateral direction D12) is the lateral extension direction parallel to the lateral center lines C13 and C14. In an example, the connecting line of the two ends of the handle 1330 is parallel to and in the same vertical plane as the lateral center line C13 of the carrier 130, so that the user can keep the balance when carrying the carrier 130 by the handle 1330.

[0617] Referring to Figure 1C and Figure 1D , Figure 1C is a perspective view of the wheeled moving device 11 after the removal of the box of the carrier 130, and Figure 1D is a top perspective view of the wheeled moving device 11 after the removal of the box.

[0618] As shown in Figure 1C and Figure 1D , the carrier 130 further comprises a bracket device 1310, which comprises a first bracket 1311, a second bracket 1312, and a third bracket 1313. When the carrier 130 is mounted on the socket assembly 120, the bracket device 1310 (e.g., the third bracket 1313) of the carrier 130 is engaged with the socket assembly 120, so that the carrier 130 can be stably mounted on the frame 110 through the socket assembly 120. In the bracket device 1310, the first bracket 1311 is in a substantially rectangular structure, which is substantially horizontally disposed at the upper end of the bracket device 1310 and is configured as the upper frame of the bracket device 1310, and is used to connect the handle 1330; the third bracket 1313 is substantially horizontally disposed at the lower end of the bracket device 1310, and is used to engage with the socket assembly 120 (as shown in the partial enlarged view in Figure 1C ); and the second bracket 1312 is connected between the first bracket 1311 and the third bracket 1313. In an embodiment, the second bracket 1312 comprises a plurality of U-shaped structures arranged in parallel and forms the side frame and the bottom frame of the bracket device 1310, so as to contact and support the side and bottom of the box of the carrier 130 (for the sake of clear description of the bracket device 1310, Figure 1C the box is not shown in Figure 1B and Figure 1C It can be seen that the second bracket 1312 extends from one side of the periphery of the box 1340 (i.e., the bearing part) to the other side of the periphery of the box 1340 through the bottom of the box 1340.

[0619] In an embodiment, in combination withFigure 1C and Figure 1D As shown in FIG. 13B, the third bracket 1313 includes an engaging member 13131, two first structural reinforcing members 13132, and a second structural reinforcing member 13133. The engaging member 13131 is in the form of a ring-shaped structure (e.g., a substantially rectangular ring-shaped structure). The two first structural reinforcing members 13132 are respectively connected to the ring-shaped structure of the engaging member 13131 (e.g., connected to two opposite long sides of the ring-shaped structure of the engaging member 13131), and are spaced apart from each other and extend substantially along the transverse direction D12 of the carrier 130. In an example, as shown in FIG. 13B, the two first structural reinforcing members 13132 are respectively arranged at the lower ends of the second bracket 1312 (e.g., the lower side of the U-shaped structure of the second bracket 1312), and are fixedly connected to the second bracket 1312 to serve as support and fixation. For example, the two first structural reinforcing members 13132 can be symmetrically arranged with respect to the transverse center line C13 of the carrier 130. The second structural reinforcing member 13133 is substantially perpendicularly connected between two opposite sides (e.g., two long sides of the rectangular structure) of the ring-shaped structure of the engaging member 13131, so as to reinforce the impact resistance of the overall structure of the third bracket 1313. In the present embodiment, the third bracket 1313 can include at least one second structural reinforcing member 13133. Alternatively, as shown in FIG. 13C, the third bracket 1313 includes two second structural reinforcing members 13133 symmetrically arranged with respect to the transverse center line C13 of the carrier 130, to provide positioning guide to help the carrier 130 to be locked at a substantially central position, thereby improving the stability of the carrier 130 when mounted on the wheeled mobile device 11. By arranging at least one third structural reinforcing member 13133, the impact resistance of the overall structure of the third bracket 1313 is further reinforced. In an example, as shown in FIG. 13B and FIG. 13C, the second structural reinforcing member 13133 is arranged in a spaced-apart manner with respect to the first structural reinforcing member 13132. Figure 1C Figure 1D Figure 1C and Figure 1D

[0620] In an example, the at least one second structural reinforcing member 13133 can be configured as a separate component connected to the engaging member 13131. In an alternative example, the at least one second structural reinforcing member 13133 can also be configured as an integral part of the engaging member 13131.

[0621] In an example, two ends of each of the first structural reinforcing member 13132 and the second structural reinforcing member 13133 can be further provided with a plurality of guide members 13132a, 13133a on both sides of each end, so as to further define the position of the carrier 130 engaged on the cartridge assembly 120, and to reduce the movement range of the carrier 130 along the longitudinal direction D11 when mounted on the cartridge assembly 120.

[0622] According to an embodiment of the present disclosure, as shown in FIG. 13B and FIG. 13C, the third bracket 1313 can include at least one second structural reinforcing member 13133.​​​Figure 1D As shown (wherein one of the engagement points is shown in the form of a partial enlarged view), the carrier 130 has multiple engagement points, for example, 4 engagement points, when the carrier 130 is mounted on the seat assembly 120. The 4 engagement points are generally symmetrically distributed with respect to the longitudinal center line C11 of the carrier 130 (and the longitudinal center line C12 of the seat assembly 120), and symmetrically distributed with respect to the transverse center line C13 of the carrier 130 (and the transverse center line C14 of the seat assembly 120). For example, the 4 engagement points are symmetrically arranged at the center of the seat assembly 120. In an embodiment, the multiple engagement points are located between the two first structural reinforcements 13132 (in combination with Figure 1C As shown, Figure 1D the first structural reinforcement is blocked by the second bracket 1312) and further, between the first structural reinforcement 13132 and the second structural reinforcement 13133. For example, in an embodiment where two second structural reinforcements 13133 are provided, the two second structural reinforcements 13133 can be arranged between the structural reinforcements 13132, and the multiple engagement points are located between the two first structural reinforcements 13132 and their adjacent second structural reinforcements 13133.

[0623] Thus, by positioning the bottom center of the carrier 130 substantially symmetrically on the seat assembly 120, the embodiments of the present disclosure enable the carrier 130 to be stably mounted on the seat assembly 120 and the frame 110, and in combination with the distribution of the multiple engagement points of the seat assembly 120 described above, the user can easily place the carrier 130 symmetrically on the frame 110, and optionally, can also easily place the carrier 130 centrally, thereby improving the overall stability of the wheeled mobility device 11, enabling the mobility device to maintain balance during travel, while also providing better impact resistance and safety. In another embodiment, the carrier 130 can also be placed non-centrally on the seat assembly 120 according to actual application requirements, and the present disclosure does not limit the multiple possible engagement positions of the carrier 130 relative to the seat assembly 120.

[0624] Referring to Figure 2 which schematically shows the frame 110 according to an embodiment of the first aspect of the present disclosure.

[0625] As Figure 2 shown, the frame 110 of the present embodiment includes a front support rod 1110, a rear support rod 1120, an upper support rod 1130, a handrail 1140, and a wheel set 1150. The wheel set 1150 includes front wheels 1150a and rear wheels 1150b, which are respectively connected to the front support rod 1110 and the rear support rod 1120.

[0626] In one embodiment, the front support rod 1110 can have a U-shaped structure, the rear support rod 1120 can be formed by two parallel rod members fixedly connected by a cross rod, and the two ends of the front support rod 1110 are respectively pivotally connected to one end of the two rod members of the rear support rod 1120. The lower side of the front support rod 1110 (i.e., the lower side of the U-shaped structure) is connected with at least one front wheel 1150a, and the other end of the two rod members of the rear support rod 1120 is respectively connected to a corresponding rear wheel 1150b. As shown in Figure 2 , in the present embodiment, two front wheels 1150a are provided, which are centrally symmetric and pivotally arranged on the lower side of the front support rod 1110. As an example, both of the two front wheels 1150a are universal wheels, and the two rear wheels 1150b are respectively rotatably connected to the two rod members of the rear support rod 1120 and can rotate in the front-rear direction of the frame 110.

[0627] Although some embodiments of the present disclosure have been listed above, the present disclosure is not limited to the structures and numbers of the above-mentioned components. For example, in other embodiments, the rear support rod 1120 can have a U-shaped structure and connect two rear wheels 1150b. Alternatively, the front support rod 1110 can also have a V-shaped or I-shaped structure, or only one front wheel 1150a is provided. In addition, the front wheel 1150a can be a unidirectional wheel, or the rear wheel 1150b can be a universal wheel.

[0628] In the present embodiment, the distance between the two front wheels 1150a is less than the distance between the two rear wheels 1150b, so as to improve the stability of the frame 110 and make it easier to turn.

[0629] Referring to Figures 3A-3C , which schematically shows the card holder assembly 120 according to an embodiment of the present disclosure. Specifically, Figure 3A is a perspective view of the card holder assembly 120, Figure 3B is a side view of the card holder assembly 120, and Figure 3C is a sectional view taken along line B-B in Figure 3A .

[0630] As shown in Figure 3A , the card holder assembly 120 includes a seat plate 1210, a locking mechanism, and a support structure 1240. Among them, the seat plate 1210 includes an upper shell and a lower shell, and since the locking mechanism is arranged in the seat plate 1210, it is shielded by the upper shell of the seat plate 1210 in Figure 3A , and its specific structure will be described below in the description of Figure 10A and Figure 10B .

[0631] In an embodiment of the present disclosure, the support structure 1240 can include two support frames 1241, which are respectively arranged on the two sides of the seat plate 1210 in the transverse direction (only one support frame 1241 is shown due to the shielding of the seat plate 1210, Figure 3A For example, the two support frames 1241 are symmetrically arranged on the two sides of the seat plate 1210 with respect to the longitudinal center line C15 of the seat plate 1210. It should be noted that the longitudinal center line C15 extends along the longitudinal direction D11 as Figure 3A indicated.

[0632] Further referring to Figure 3B and Figure 3C , each support frame 1241 includes a longitudinal rod 12411, a connecting rod 12412, and a shock-absorbing rod 12413 connected in a triangular structure. Among them, the longitudinal rod 12411 is arranged below the seat plate 1210 and fixedly connected with the seat plate 1210 (for example, the lower shell thereof); the first end 12412a of the connecting rod 12412 is pivotally connected with the first end 12411a of the longitudinal rod 12411 (as indicated in Figure 3C ), the second end 12412b of the connecting rod 12412 is fixedly connected with the first end 12413a of the shock-absorbing rod 12413, and the second end 12413b of the shock-absorbing rod 12413 is fixedly connected to the second end 12411b of the longitudinal rod 12411, for example, arranged at the middle rear segment of the seat plate 1210 in the longitudinal direction D11 thereof. In an embodiment, the shock-absorbing rod 12413 is elastic to provide cushioning support to the seat plate 1210. For example, the shock-absorbing rod 12413 is a compression spring, a hydraulic rod, a pneumatic rod, or other elastic structure.

[0633] Through the triangular structure of the support frame 1241, the card seat assembly 120 can be stably arranged on the frame (not shown in Figures 3A-3C , and the specific arrangement will be described in the description of Figures 5A-5B below), and by arranging the shock-absorbing rod 12413, when the frame is subjected to bumps, a certain degree of buffering can be provided for the object mounted on the seat plate 1210.

[0634] In the present embodiment, the upper end of the shock-absorbing rod 12413 is arranged at the position of the second end 12411b of the longitudinal rod 12411 (corresponding to the middle rear section of the seat plate 1210), which has a better shock-absorbing stroke, thereby achieving a better shock-absorbing effect. However, the present disclosure is not limited thereto. In another embodiment, by adjusting the length of the longitudinal rod 12411 to adjust the connection position of the shock-absorbing rod 12413 and the longitudinal rod 12411 relative to the seat plate 1210, the cushioning capacity of the support frame 1241 can be adjusted, such as being arranged at a central position or an extreme end relative to the seat plate 1210, and the like. In yet another embodiment, the cushioning capacity of the support frame 1241 can also be adjusted by adjusting the length of the connecting rod 12412 within a predetermined range, setting the included angle between the connecting rod 12412 and the longitudinal rod 12411, the included angle between the connecting rod 12412 and the shock-absorbing rod 12413, and / or the included angle between the shock-absorbing rod 12413 and the longitudinal rod 12411. Even, the elastic coefficient of the shock-absorbing rod 12413 can also be adjusted, such as the spring pitch, diameter and material of the compression spring, the pressure force of the pneumatic or hydraulic rod, and the like, to achieve a better shock-absorbing effect.

[0635] In addition, as shown in Figure 3B and Figure 3C , the longitudinal rod 12411 further comprises a limiting finger 12411c arranged at the first end 12411a of the longitudinal rod 12411 close to one side of the connecting rod 12412, for limiting the angle of downward pivoting of the longitudinal rod 12411 relative to the connecting rod 12412. When traveling on a bumpy road, the shock-absorbing rod 12413 deforms (such as shortens or bends) to provide cushioning, so that the longitudinal rod 12411 pivots downward relative to the connecting rod 12412. When the limiting finger 12411c arranged below the longitudinal rod 12411 abuts against the connecting rod 12412, the longitudinal rod 12411 will not continue to pivot downward (i.e., the angle between the longitudinal rod 12411 and the connecting rod 12412 will not continue to decrease), thereby avoiding the inclination angle of the longitudinal rod 12411 relative to the horizontal plane being too large, and thereby avoiding the inclination amplitude of the seat plate 1210 and the objects arranged thereon being too large, further improving the safety and driving stability.

[0636] As shown in Figure 3CAs shown, in an embodiment, the longitudinal rod 12411 can further include a limiting protrusion 12411d disposed on the side opposite to the limiting finger 12411c at the first end 12411a of the longitudinal rod 12411, and the limiting protrusion 12411d is located between the longitudinal rod 12411 and the upper shell of the seat plate 1210, for limiting the upward pivoting of the longitudinal rod 12411 relative to the connecting rod 12412. For example, as described above, when traveling on a bumpy road, the longitudinal rod 12411 will pivot downward or upward relative to the connecting rod 12412 along with the deformation or recovery of the shock rod 12413, wherein when the shock rod 12413 recovers the deformation, a force will be applied to the longitudinal rod 12411 to make it pivot upward, and the limiting protrusion 12411d prevents the seat plate 1210 from pivoting upward at an excessively large angle along with the longitudinal rod 12411, which will cause the connection between the longitudinal rod 12411 and the connecting rod 12412 to break. In addition, after the seat plate 1210 and the frame (not shown in the figure) are folded as a whole (for the folding process, please refer to the description below), the user can lift the entire frame structure by pulling the two ends of the seat plate 1210 in the longitudinal direction D11, at which time the limiting protrusion 12411d can also prevent the seat plate 1210 from turning outward due to a larger force applied to the tail end (i.e., the right end as shown) of the seat plate 1210, thereby further improving the safety and structural stability of use. Figures 7-8B Figure 3C

[0637] For reference, Figure 4 which schematically shows a support structure 1240 according to an embodiment of the first aspect of the present disclosure.

[0638] In an embodiment, the support structure 1240 further includes a transverse rod or a first connecting rod 1242 in the shape of a U, which is connected between the longitudinal rods 12411 of the two support frames 1241 to fix the connection between them. For example, as shown in Figure 4 , the first connecting rod 1242 connects the second ends 12411b of the longitudinal rods 12411 of the two support frames 1241 together. Optionally, the second ends 12411b of the longitudinal rods 12411 of the two support frames 1241 are respectively sleeved on the two ends of the first connecting rod 1242. In another embodiment, the support structure 1240 further includes a second connecting rod 1243 connected between the connecting rods 12412 of the two support frames 1241. Optionally, the first connecting rod 1242 and the second connecting rod 1243 are respectively connected with the two ends of the two longitudinal rods 12411, or are integrally formed with the two longitudinal rods 12411 as a rectangular frame structure.

[0639] Figure 5A and Figure 5B schematically shows a support structure 1240' according to another embodiment of the first aspect of the present disclosure. Among them, Figure 5A ​​A perspective view of the support structure 1240' is shown, and Figure 5B A plan view of the support structure 1240' as viewed from the inside is shown.

[0640] like Figure 5A As shown, the support structure 1240' has a similar structure to the support structure 1240, also including two support frames 1241', and the support frame 1241' includes a longitudinal rod 12411', a connecting rod 12412' and a shock-absorbing rod 12413'. The difference is that the support frame 1241' may also include a limiting member 12414'.

[0641] Combination Figure 5B As shown, the first end 12414'a of the limiting member 12414' is slidably connected to the longitudinal rod 12411', and the second end 12414'b of the limiting member 12414' is connected to the second end 12412'b of the connecting rod 12412'. In one embodiment, a limiting groove 12414'c extending a certain distance along its length direction is provided at the first end 12414'a of the limiting member 12414', and a pin 12411'e is provided at the middle section of the longitudinal rod 12411'. Through the cooperation of the limiting groove 12414'c and the pin 12411'e, the limiting member 12414' can slide in a direction that is substantially vertical relative to the longitudinal rod 12411' (e.g., vertically or substantially vertically). Optionally, when there is no relative displacement between the limiting member 12414' and the longitudinal rod 12411', the pin 12411'e is disposed on the longitudinal rod 12411' and the second end 12412'b of the connecting rod 12412' is in the vertical direction (e.g., Figure 5B At the corresponding position in the direction D13 shown. In other words, when there is no relative sliding between the limiting member 12414' and the longitudinal rod 12411' (i.e., the initial state), the pin 12411'e is located at the uppermost end of the limiting groove 12414'c, and the limiting member 12414' is generally perpendicular to the longitudinal rod 12411'. When traveling on a bumpy road, the shock absorber 12413' deforms (e.g., shortens or bends) to provide cushioning, causing the longitudinal rod 12411' to pivot downward relative to the connecting rod 12412'. At this time, the limiting groove 12414'c of the limiting member 12414' restricts the sliding stroke of the pin 12411'e of the longitudinal rod 12411' (i.e., corresponding to the length of the limiting groove 12414'c), thereby limiting the pivoting of the longitudinal rod 12411' relative to the connecting rod 12412' within a certain range. Therefore, it is possible to prevent the longitudinal rod 12411' and the seat plate fixed thereon from being damaged. Figure 5B Not shown, please refer to Figures 3A-3CThe seat plate 1210 is inclined downward relative to the connecting rod 12412' during the buffering action, while also being able to prevent the seat plate and the frame in the folded state from being moved by the user lifting the seat plate (as shown in Figure 9A The possibility of the longitudinal rod 12411' and the seat plate thereon being everted (i.e., the longitudinal rod 12411' being pivoted upward relative to the connecting rod 12412') is shown. In other words, relative to the limiting finger 12411'c and the limiting block 12411'd, the limiting member 12414' can further limit the pivoting of the longitudinal rod 12411', and even be able to simultaneously achieve the effects of both the limiting finger 12411'c and the limiting block 12411'd. However, the present disclosure is not limited thereto. In other embodiments, only the limiting member 12414' can be provided, without the limiting finger 12411'c and the limiting block 12411'd.

[0642] Referring to Figures 6A-6C , which schematically shows a frame 110 provided with a seat assembly 120 according to an embodiment of the first aspect of the present disclosure. In this embodiment, Figure 6A and Figure 6B are perspective views of the frame 110 and the seat assembly 120 provided thereon from different angles, and Figure 6C is a side view of the frame 110 and the seat assembly 120.

[0643] As shown in Figures 6A-6C , the seat assembly 120 is pivotably connected and mounted to the frame 110 through its support structure 1240, wherein the seat plate 1210 and the locking mechanism (the locking mechanism is blocked in the figure, and its specific structure will be described below) of the seat assembly 120 are fixedly mounted on the support structure 1240, and the seat plate 1210 provides a generally horizontal plane for placing objects (in this embodiment, a carrier). The support structure 1240 further includes a first connecting component 1244 and a second connecting component 1245, which are respectively pivotably connected to the frame 110. Through the provision of the first connecting component 1244 and the second connecting component 1245, the seat assembly 120 can be folded together with the frame 110. The specific connection between the support structure 1240 and the frame 110, and the mechanism for folding the seat assembly 120 together with the frame 110 will be described below.

[0644] Please refer to Figure 7 , which schematically shows a frame 110 provided with a support structure 1240 according to an embodiment of the first aspect of the present disclosure.

[0645] As shown in Figure 7As shown, one end of the first connecting member 1244 and the second connecting member 1245 are pivotably connected with the second end 12412b of the connecting rod 12412 respectively, and the other end of the first connecting member 1244 and the second connecting member 1245, and the first end 12412a of the connecting rod 12412 are pivotably connected at different positions on the frame 110 which can pivot relative to each other respectively. Through this connection mode of the first connecting member 1244 and the second connecting member 1245, the support structure 1240 is pivotably mounted on the frame 110 so as to provide a supporting effect on the card seat assembly (for the sake of clarity, the structure of the card seat assembly other than the support structure 1240 is removed in the figure) and can be folded together with the frame 110.

[0646] Specifically, as shown in Figure 7 , one end of the first connecting member 1244 is pivotably connected with the second end 12412b of the connecting rod 12412, and the other end of the first connecting member 1244 is pivotably connected with the upper support rod 1130 of the frame 110; one end of the second connecting member 1245 is pivotably connected with the second end 12412b of the connecting rod 12412, and the other end of the second connecting member 1245 is pivotably connected with the rear support rod 1120; and the first end 12412a of the connecting rod 12412 is pivotably connected with the front support rod 1110, so that the support frame 1241 together with the entire card seat assembly 120 can pivot with the pivoting of the frame 110, thereby realizing overall folding.

[0647] Referring to Figures 8A-9B , which schematically shows the folding process of the frame 110 mounted with the card seat assembly 120 according to an embodiment of the first aspect of the present disclosure. Among them, Figure 8A and Figure 8B show the perspective view and side view of the frame 110 together with the card seat assembly 120 mounted thereon in the folding process, and Figure 9A and Figure 9B show the front view and side view of the frame 110 together with the card seat assembly 120 mounted thereon being completely folded.

[0648] As shown in Figure 8A , the frame 110 of the present embodiment can be folded for carrying and storage. Specifically, the handrails 1140 of the frame 110 are pivotably connected with the upper support rod 1130 through the pivoting part 1131 and can be folded relative to the upper support rod 1130. The front support rod 1110, the rear support rod 1120 and the upper support rod 1130 are pivoted at the first pivot point A11 and can be folded relative to each other. In addition, the frame 110 can also drive the support structure 1240 to pivot when it is folded, so that the card seat assembly 120 mounted on the support structure 1240 can also pivot with the folding of the frame 110.

[0649] Furthermore, as shown in Figure 8B support structure 1240 is pivotably connected to the upper support bar 1130 of the frame 110 at a second pivot point A12 via a first connecting member 1244, to the rear support bar 1120 at a third pivot point A13 via a second connecting member 1245, and to the front support bar 1110 at a fifth pivot point A15 via a connecting bar 12412, respectively. The first connecting member 1244 and the second connecting member 1245 are connected to the connecting bar 12412 at a fourth pivot point A14.

[0650] With the above connection relationship, the first connecting member 1244, the second connecting member 1245, the upper support bar 1130 and the rear support bar 1120 form a four-bar linkage mechanism through the first, second, third and fourth pivot points A11, A12, A13, A14, the front support bar 1110, the rear support bar 1120, the second connecting member 1245 and the connecting bar 12412 form a four-bar linkage mechanism through the first, third, fourth and fifth pivot points A11, A13, A14, A15, and the front support bar 1110, the upper support bar 1130, the first connecting member 1244 and the connecting bar 12412 form a four-bar linkage mechanism through the first, second, fourth and fifth pivot points A11, A12, A14, A15, so that the cradle assembly 120 can be pivoted to be accommodated in the overall structure of the frame 110 as the frame 110 is folded (the final completed folding state is shown in Figure 9B ).

[0651] In combination with Figure 9A and Figure 9B , when the frame 110 is completely folded, i.e., the front support bar 1110, the rear support bar 1120, the upper support bar 1130 and the armrest 1140 are folded to the closest positions relative to each other, the cradle assembly 120 is accommodated between the upper support bar 1130 and the front support bar 1110 and the rear support bar 1120 as it is pivoted.

[0652] Furthermore, as shown in Figure 9A , the seat plate 1210 can include a handle 1211. When the frame 110 and the cradle assembly 120 are completely folded, the handle 1211 is located above the entire structure after folding, so that a user can easily grasp the handle 1211 to move the frame 110 (together with the cradle assembly 120).

[0653] Reference is made to Figure 10A and Figure 10B which schematically illustrate a cradle assembly 120 according to an embodiment of the first aspect of the present disclosure. Figure 10A and Figure 10B are perspective views of the cradle assembly 120, wherein FIG. 10AThe upper housing of the seat plate 1210 was removed to allow for observation of the locking mechanism 1220 located within the seat plate 1210.

[0654] Combination FIG. 10A and FIG. 10B As can be seen, the locking mechanism 1220 is installed inside the seat plate 1210 for locking and releasing objects (e.g., sleeping boxes, other animal or infant carriers) located on the seat plate 1210.

[0655] like FIG. 10A As shown, the locking mechanism 1220 includes at least one release operating member 1221 and at least one locking member 1222. The release operating member 1221 is disposed within the base plate 1210 and is movable relative to the base plate 1210 between a locked position and an unlocked position. The locking member 1222 is movable accordingly as the release operating member 1221 moves. When the release operating member 1221 is in the locked position... FIG. 10B In the locked position, at least a portion of the release mechanism 1221 protrudes from the base plate 1210, locking an object placed on the base plate 1210. When the release mechanism 1221 is pressed and moved inward from the locked position to the unlocked position, the locking member 1222 moves along with the release mechanism 1221, thereby releasing the object on the base plate 1210. In this embodiment, as shown... FIG. 10B As shown, at least a portion of the release operation member 1221 protrudes outward from the side of the base plate 1210.

[0656] like FIG. 10A As shown, in one embodiment, at least one locking member 1222 may include a plurality of front locking members 12221, which can be connected to each other via a linkage assembly 12231, so that the locking members 1222 located on the same side of the seat plate 1210 can move synchronously. For example, the plurality of front locking members 12221 can be rigidly connected (i.e., fixedly connected) and move in the same direction, or the plurality of front locking members 12221 can be connected via a linkage assembly 12231, such as... FIG. 10A The linkage component 12231 shown is connected and moves in opposite directions. Similarly, at least one locking member 1222 may also include multiple rear locking members 12222, which can be connected to each other by another linkage component 12231, so that the locking members 1222 located on the other side of the seat plate 1210 can move synchronously.

[0657] In another embodiment, the at least one locking member 1222 can include at least one front locking member 12221 and at least one rear locking member 12222, wherein the front locking member 12221 is arranged on one side of the seat plate 1210 and fixedly connected with the corresponding release operating member 1221, and the rear locking member 12222 is arranged on the other side of the seat plate 1210 opposite to the side where the front locking member 12221 is arranged, and the front locking member 12221 and the rear locking member 12222 are connected by a linkage (for example, FIG. 10A “12232” in FIG. 12B and FIG. 14A “12232’” in FIG. 12C, which will be described below) so that the locking members 1222 arranged on different sides of the seat plate 1210 can move synchronously.

[0658] Here, the linkage assembly 12231 and the linkage are collectively referred to as “linkage device” for connecting between the locking members 1222 to enable the locking members 1222 to move together correspondingly with the movement of the release operating member 1221, thereby achieving synchronous release or synchronous locking of the object by the plurality of locking members 1222.

[0659] For example, as shown in FIG. 10A , an embodiment of the first aspect of the present disclosure is provided with two release operating members 1221. Among them, the two release operating members 1221 are respectively arranged on the two sides of the seat plate 1210 in the transverse direction (i.e., along the transverse direction D12), and can move relative to the seat plate 1210 between the respective locking position and the release position. Correspondingly, the embodiment is also provided with two front locking members 12221 and two rear locking members 12222. The two front locking members 12221 are movably arranged on one side of the seat plate 1210 and fixedly connected with the corresponding (for example, adjacent) release operating member 1221. The two rear locking members 12222 are movably arranged on the other side of the seat plate 1210 (i.e., the side opposite to the side where the two front locking members 12221 are arranged) and connected with the corresponding front locking member 12221 by a linkage.

[0660] For example, the two front locking members 12221 can be arranged on the front side of the seat plate 1210 (as shown in the lower left of FIG. 10A as the front side of the seat plate 1210) and fixedly connected with the adjacent release operating member 1221, and the two rear locking members 12222 are arranged on the rear side of the seat plate 1210 (as shown in the upper right of FIG. 10A as the rear side of the seat plate 1210) and connected to the two front locking members 12221 by the respective linkages to move synchronously with the two front locking members 12221. More specifically, as shown in FIG. 10BAs shown, the two release operating members 1221 are symmetrically arranged on two sides of the seat plate 1210 relative to a center line C15 of the seat plate 1210, and the two front locking members 12221 are symmetrically arranged between the two release operating members 1221 relative to the center line C15 of the seat plate 1210 and are fixedly connected to the release operating members 1221 on the adjacent side, respectively, wherein the center line C15 of the seat plate 1210 extends along the longitudinal direction D11 of the seat plate 1210.

[0661] In an embodiment, as shown, FIG. 10A Specifically, the traction member 12232 can be arranged to extend along the outer periphery of the locking mechanism 1220 in the seat plate 1210, and the front locking member 12221 and the corresponding rear locking member 12222 diagonally arranged relative to the center line C15 of the seat plate 1210 can be connected to each other by the traction member 12232, so that the moving directions of the front locking member 12221 and the rear locking member 12222 connected by the same traction member 12232 are opposite. For example, the two front locking members 12221 on the front side are connected to the rear locking members 12222 diagonally arranged relative to the front locking members 12221 by the corresponding traction members 12232, so that when the release operating member 1221 is operated, the front locking member 12221 is driven to move towards the center line C15, and in turn, the rear locking member 12222 connected to the front locking member 12221 (diagonally arranged relative to the front locking member 12221) is driven to move towards the opposite direction, i.e., the direction opposite to the front locking member 12221, thereby causing the rear locking member 12222 to also move towards the center line C15; and when the release operating member 1221 is released, the front locking member 12221 and the rear locking member 12222 are both driven to move away from the center line C15. In addition, in other embodiments, the front locking member 12221 and the rear locking member 12222 on the same side of the center line C15 of the seat plate 1210 can be connected by the traction member 12232, so that when the release operating member 1221 is operated, the moving directions of the front locking member 12221 and the rear locking member 12222 are still opposite, but the front locking member 12221 moves towards the center line C15, and the rear locking member 12222 moves away from the center line C15.

[0662] In the present embodiment, the traction member 12232 can be a steel wire, which is covered by a steel wire sleeve and hidden in the seat plate 1210. In other embodiments, the traction member 12232 can also be a flexible member such as a composite material wire.

[0663] As shown, FIG. 10AAs shown, in this embodiment, a linkage assembly 12231 is further provided between the two front locking members 12221 and / or between the two rear locking members 12222, so as to synchronize the reverse movement of the two front locking members 12221 relative to each other and the two rear locking members 12222 relative to each other about the center line C15. For example, the linkage assembly 12231 is a four-bar linkage mechanism formed by two-by-two connection (specifically, two-by-two hinging) of four sheet-like bars, wherein the mechanism has a pivot point fixed to the seat plate (please refer to FIG. 10B the upper shell of the seat plate 1220 is removed in order to show the structure of the locking mechanism 1220, FIG. 10A the mechanism can extend to both sides (corresponding to the locking position of the release operation member 1221) and shorten (corresponding to the release position of the release operation member 1221) about the center line at the position of the pivot point. Specifically, the four-bar linkage mechanism includes a first bar, a second bar, a third bar, and a fourth bar, which are connected two-by-two to form four connection points, one of which is a fixed connection point P1 fixed to the fixed structure (for example, the seat plate 1220) of the card holder assembly 120, and the connection point opposite to the fixed connection point P1 is a center connection point P2. The bars connected through the center connection point P2 in the four-bar linkage mechanism are connected to the two front locking members and / or the two rear locking members, respectively.

[0664] Through the linkage assembly 12231 as described above, when at least one release operation member 1221 is moved from the locking position to the release position, the locking member 1222 connected to the release operation member 1221 moves together with the release operation member 1221 and has the same moving direction, while the moving direction of the center connection point P2 of the linkage assembly 12231 is perpendicular to the moving direction of the locking member 1222 and / or the release operation member 1221.

[0665] Through the cooperation of the linkage assembly 12231 and the linkage member (for example, the traction member 12232), when the release operation member 1221 is in the locking position, the user can operate any release operation member 1221 to move it from the locking position to the release position, thereby driving the front locking member 12221 connected thereto to move, and then synchronously reversely moving (for example, moving closer to each other) the two front locking members 12221 under the action of the linkage assembly 12231, and reversely moving (for example, moving closer to each other) the rear locking members 12222 under the action of the linkage member. At this time, the front locking members 12221 and the rear locking members 12222 simultaneously release the object. When the release operation member 1221 is moved from the release position to the locking position, the two front locking members 12221 synchronously move away from each other, and the two rear locking members 12222 also synchronously move away from each other.

[0666] In other embodiments, the two front locking members 12221 and / or the two rear locking members 12222 can also move synchronously in the same direction via a linkage assembly 12231.

[0667] In addition, such as FIG. 10A As shown, the card holder assembly 120 also includes an elastic device 1224 that provides a force to drive the release actuation member to or return to the locked position. In one embodiment, the elastic device 1224 is disposed between two front locking members 12221, constantly providing a force to drive the two front locking members 12221 away from each other. Optionally, the elastic device 1224 may also be disposed between two rear locking members 12222, constantly providing a force to drive the two rear locking members 12222 away from each other. For example, the elastic device 1224 may be a compression spring. In other embodiments, when locking members located on the same side (e.g., two locking members on the front side, or two locking members on the rear side, or two locking members on the right side, or two locking members on the left side) move in the same direction, the locking members may be fixedly connected, with at least one of the locking members being fixed to the card holder assembly 120 by a fixing structure (e.g., such as...) FIG. 10B An elastic device is provided between the seat plates 1210 shown, so that the release operating member 1221 tends to be in the locked position. It should be noted that the terms "front side," "rear side," "right side," and "left side" here refer to... FIG. 10A The direction shown, for example, FIG. 10A The lower left side of the card holder assembly 120 is the front side, and the upper right side is the rear side of the card holder assembly 120, etc.

[0668] In addition, the elastic device 1224 may also be provided between one of the locking members and the base plate (e.g., in the case of a fixed connection between the front locking member and the rear locking member) to provide a force that drives the release operation member to the locked position or back to the locked position.

[0669] like FIG. 10A As shown, in one embodiment, the two front locking members 12221 are respectively fixedly connected to the corresponding release operation member 1221 via corresponding sliding members 1225. The sliding members 1225 can slide in the groove of the locking mechanism 1220, so that when the user operates the release operation member 1221, the front locking members 12221 and the release operation member 1221 connected by the sliding members 1225 slide synchronously, thereby causing the two front locking members 12221 to slide relative to each other. In addition, the front locking members 12221 and the release operation member 1221 can also be connected by other means, such as bolt connection, adhesive, etc.

[0670] Optionally, the slider 1225 can be integrally formed with the release operation member 1221.

[0671] In addition, in one embodiment, please also refer toFIG. 10B and FIG. 10B One end of the front locking member 12221 is provided with a locking portion 12221a (shown in FIG. 10B FIG. 13B), and the seat plate 1210 is provided with an opening at a position corresponding to the locking portion 12221a, so that when the upper housing of the seat plate 1210 is mounted above the locking mechanism 1220, the locking portion 12221a can protrude from the opening of the seat plate 1210. For example, the seat plate 1210 has a front-side raised upper housing structure, i.e., the front-side portion of the upper housing of the seat plate 1210 can form a housing structure with a larger height (compared to the middle portion), and a recessed portion 1212 is provided on the raised structure of the housing structure at a position corresponding to the end of the front locking member 12221, and the recessed portion 1212 penetrates the raised structure in the longitudinal direction D11 for accommodating at least a portion of the object. The recessed portion 1212 is provided with an opening for the locking portion 12221a of the front locking member 12221 to protrude from the seat plate 1210, and the locking portion 12221a protruding from the opening is located within the recessed portion 1212 (i.e., the space formed thereby). The rear side of the seat plate 1210 (i.e., the position corresponding to the rear locking member 12222) can also have the same structure (i.e., the raised structure, the recessed portion, and the opening thereof, etc.), which will not be described here. When the object is placed on the seat plate 1210, the recessed portion 1212 accommodates at least a portion of the object (e.g., the support device structure of the sleeping bag), and the locking portion 12221a protrudes from the opening and locks the portion of the object in the recessed portion 1212. In an embodiment, as shown in FIG. 6A , the upper surface of the portion of the locking portion 12221a protruding from the opening is a downwardly inclined surface, facilitating the movement of the portion of the object used for locking along the inclined surface to enter the recessed portion 1212. It should be noted here that the "front side" or "rear side" of the aforementioned seat plate 1210 can be understood as follows: when the seat plate 1210 is arranged on the wheeled mobile device 11 as shown in FIG. 10B , the side of the seat plate 1210 facing the advancing direction of the wheeled mobile device 11 is the "front side" thereof, and the side of the seat plate 1210 facing the retreating direction of the wheeled mobile device 11 is the "rear side" thereof. In addition, the aforementioned longitudinal direction D11 can be considered as the front-rear direction of the wheeled mobile device 11 (and the seat plate 1210).

[0672] In addition, as shown in FIG. 11A-11B , the raised upper housing structure (specifically, the raised structure) of the seat plate 1210 is further provided with an inclined surface 1213 located above the recessed portion 1212 and on the side opposite to the opening of the recessed portion 1212 (i.e., the position of the locking portion 12221a), for guiding the locking of the object (e.g., the carrier, not shown in the figure) and the cartridge assembly 120.

[0673] Referring to FIG. 11A which shows the locked state and the released state of the locking mechanism 1220 according to an embodiment of the first aspect of the present disclosure. Specifically, FIG. 10B shows a cross-sectional view taken along line E-E in FIG. 11B , wherein the locking mechanism 1220 is in the locked state; and FIG. 11A shows the locking mechanism 1220 switching from the locked state to the released state as shown in FIG. 11A .

[0674] As shown in FIG. 11A , when the locking mechanism 1220 is in the locked state, the release operating members 1221 are in the locked position (i.e. the initial position), and the front locking members 12221 fixedly connected with the two ends of the release operating members 1221 respectively are in their locked position, i.e. the locking portions 12221a of the front locking members 12221 protrude out of the seat plate 1210. Meanwhile, the rear locking members 12232 also remain in their locked position. At this time, the front locking members 12221 and the rear locking members (obscured in the figure, not shown) lock the object at both sides of the seat plate 1210 along the transverse direction D12 respectively. At this time, the elastic devices 1224 between the front locking members 12221 are in the initial state (e.g. the stretched state), and optionally, the elastic devices (not shown) between the rear locking members (not shown) are also in the initial state (e.g. the stretched state). In an embodiment, the center connecting point P2 of the four-bar linkage mechanism of the linkage assembly 12231 is located at an upper position as shown in FIG. 11B , i.e. close to the fixed connecting point P1.

[0675] As shown in FIG. 11B , when one of the release operating members 1221 is operated to move from the locked position to the released position, the front locking members 12221 fixedly connected with the release operating member 1221 move along with the movement of the release operating member 1221, meanwhile, the other release operating member 1221 is synchronously moved in the opposite direction by the linkage assembly 12231, and the respective corresponding rear locking members (not shown in this figure) are synchronously moved by the linkage (in this embodiment, the “pulling member 12232”) to make the locking portions 12221a of the two front locking members 12221 and the locking portions (not shown in this figure) of the two rear locking members retract into the seat plate 1210, thereby releasing the object. At this time, the elastic devices 1224 between the front locking members 12221 are in a state tending to make the release operating members 1221 return to the locked position (e.g. the compressed state), and optionally, the elastic devices (not shown) between the rear locking members (not shown) are also in the compressed state. In an embodiment, the center connecting point P2 of the four-bar linkage mechanism of the linkage assembly 12231 is located at a lower position as shown in FIG. 11Adownward position, i.e. away from the fixed connection point P1. That is, when the release operation member 1221 is moved from the locking position to the release position, the central connection point P2 of the linkage assembly 12231 moves approximately vertically downward relative to the fixed connection point P1.

[0676] When the release operation member 1221 is released, the two release operation members 1221 are synchronously returned from the respective release positions to the locking positions, the two front locking members 12221 are moved away from each other (e.g. under the action of the elastic device 1224 between the two), while simultaneously bringing the two rear locking members (not shown) away from each other, thereby returning the locking mechanism 1220 to the locked state as shown. FIG. 11A In another embodiment, when the release operation member 1221 is released, the two rear locking members (not shown) are moved away from each other under the action of the elastic device (not shown) between the two, while simultaneously bringing the two front locking members 12221 away from each other, thereby returning the locking mechanism 1220 to the locked state as shown. FIG. 12

[0677] With reference to FIG. 12 , which shows a wheeled mobile device 11 according to an embodiment of the present disclosure, wherein the box of the carrier 130 is removed to show the connection relationship between the support device 1310 of the carrier 130 and the locking mechanism 120.

[0678] As FIG. 12 shown, when the carrier 130 (i.e. as an example of the "object" described above) is installed on the seat plate 1210 by the locking mechanism 120 (the release operation member 1221 is in the locking position), the engaging member 13131 (e.g. FIG. 13A-13B shown, the annular structure member) of the third support 1313 is partially locked in the space defined by the recess 1212 and the locking portion 12221a, so that the carrier 130 is locked to the seat plate 1210.

[0680] As FIG. 13B ​As shown, when the locking mechanism 1220 is in the locked state, the locking portions 12221a of the front locking members 12221 extend out of the openings at the recessed portions 1212 of the seat plate 1210 to lock the engaging members 13131 of the carrier 130 in the recessed portions 1212.

[0681] As shown, when the locking mechanism 1220 is in the locked state, the locking portions 12221a of the front locking members 12221 extend out of the openings at the recessed portions 1212 of the seat plate 1210 to lock the engaging members 13131 of the carrier 130 in the recessed portions 1212. FIG. 14A-14B As shown, when the locking mechanism 1220 is in the locked state, the locking portions 12221a of the front locking members 12221 extend out of the openings at the recessed portions 1212 of the seat plate 1210 to lock the engaging members 13131 of the carrier 130 in the recessed portions 1212.

[0682] As shown, when the locking mechanism 1220 is in the locked state, the locking portions 12221a of the front locking members 12221 extend out of the openings at the recessed portions 1212 of the seat plate 1210 to lock the engaging members 13131 of the carrier 130 in the recessed portions 1212. FIG. 14A As shown, when the locking mechanism 1220 is in the locked state, the locking portions 12221a of the front locking members 12221 extend out of the openings at the recessed portions 1212 of the seat plate 1210 to lock the engaging members 13131 of the carrier 130 in the recessed portions 1212.

[0683] As shown, when the locking mechanism 1220 is in the locked state, the locking portions 12221a of the front locking members 12221 extend out of the openings at the recessed portions 1212 of the seat plate 1210 to lock the engaging members 13131 of the carrier 130 in the recessed portions 1212. FIG. 14A As shown, when the locking mechanism 1220 is in the locked state, the locking portions 12221a of the front locking members 12221 extend out of the openings at the recessed portions 1212 of the seat plate 1210 to lock the engaging members 13131 of the carrier 130 in the recessed portions 1212. FIG. 14B As shown, when the locking mechanism 1220 is in the locked state, the locking portions 12221a of the front locking members 12221 extend out of the openings at the recessed portions 1212 of the seat plate 1210 to lock the engaging members 13131 of the carrier 130 in the recessed portions 1212.

[0684] As shown, when the locking mechanism 1220 is in the locked state, the locking portions 12221a of the front locking members 12221 extend out of the openings at the recessed portions 1212 of the seat plate 1210 to lock the engaging members 13131 of the carrier 130 in the recessed portions 1212.

[0685] As shown, when the locking mechanism 1220 is in the locked state, the locking portions 12221a of the front locking members 12221 extend out of the openings at the recessed portions 1212 of the seat plate 1210 to lock the engaging members 13131 of the carrier 130 in the recessed portions 1212. FIG. 15As can be seen, in one embodiment, the two ends of the connecting rod 12232' are pivotally connected from the bottom to the corresponding front locking member 12221' and rear locking member 12222', respectively. A stop member 1226' can also be provided at the bottom of the front locking member 12221' and / or the rear locking member 12222' to limit the minimum value of the included angle α between the two connecting rods 12232', that is, to prevent the two connecting rods 12232' from jamming due to an excessively small included angle, and to prevent the connecting rod 12232' from disengaging from the inner bottom of the front locking member 12221' and / or the rear locking member 12222'.

[0686] Reference FIG. 15 The illustration schematically depicts a card holder assembly 120' provided with a retaining mechanism 1250 according to an embodiment of the present disclosure, wherein the upper housing of the seat plate is removed to show the retaining mechanism 1250. FIG. 15 As shown, the card holder assembly 120' of this disclosure also includes a retaining mechanism 1250, disposed between the two front locking members 12221' and / or the two rear locking members 12222', for holding the release operation member 1221' in the released position, that is, holding the card holder assembly 120' in the released state. Thus, the user does not need to continuously perform a release operation on the release operation member 1221' (e.g., pressing the release operation member 1221') to keep the card holder assembly 120' in the released state, allowing the user to remove objects above the card holder assembly 120' at any time.

[0687] It should be noted that, although in FIG. 14B Only the use of two links is shown (e.g., FIG. 10A The embodiment shown (link 12232') connects the front locking member 12221' and the rear locking member 12222', but it should be understood that the retaining mechanism 1250 is also suitable for cases where the front locking member 12221 and the rear locking member 12222 are connected by a traction member (e.g.) FIG. 15 (Example shown).

[0688] Please refer to the above as well. FIG. 16A and FIG. 16A ,in FIG. 15 schematically showing along FIG. 15 The sectional view of the retaining mechanism 1250, taken by line FF, shows the structural relationship between the retaining mechanism 1250 and the base plate 1210'. FIG. 15 As shown, the retaining mechanism 1250 includes a touch button 1251, a latching part 1252, and a reset member 1255. FIG. 16A The middle is obscured and not shown, shown in FIG. 15 (Middle). The touch button 1251 is located on the base plate 1210' ( FIG. 16A Only the lower housing of seat plate 1210' is shown in the image; please refer to the image for the upper housing of seat plate 1210'. FIG. 16A) and can be at least partially protruded above the seat plate 1210' (in particular, the upper shell thereof, refer to FIG. 16A ) from the seat plate 1210' (in particular, the lower shell thereof, refer to FIG. 16A ) and can be vertically moved along the slide rail 1254 on the trigger button 1251. For example, the clamping portion 1252 can be a clamping pin. As shown in

[0689] Please refer to FIG. 16A In an embodiment, the retaining mechanism 1250 further comprises a resilient member 1253 arranged between the trigger button 1251 and the clamping portion 1252 for cooperating with the movement of the clamping portion 1252 relative to the trigger button 1251. In addition, the front locking member 12221' is provided with a retaining hook 12221'b at the lower side of the end of the front locking member 12221' distal to the locking portion 12221'a, so as to correspondingly hook the clamping portion 1252 of the retaining mechanism 1250. The front end of the retaining hook 12221'b can also be provided with a chamfer, so as to more stably clamp to the clamping portion 1252.

[0690] In addition, as shown in FIG. 16B When the carrier is not placed on the seat plate 1210' and the release operation of the release operation member 1221' has not been performed, the release operation member 1221' is in the locked position (i.e., the initial position), and the retaining mechanism 1250 is also in its initial position. At this time, the trigger button 1251 of the retaining mechanism 1250 protrudes above the seat plate 1210', the clamping portion 1252 is separated from the retaining hook 12221'b of the front locking member 12221', and the resilient member 1253 and the resilient member 1253 are both in the released state, i.e., not compressed.

[0691] Please refer to FIG. 16C and FIG. 16B which schematically show the operation process of the retaining mechanism 1250 when the carrier 130 is placed on the seat plate 1210' and needs to be moved away.

[0692] As shown in FIG. 16CAs shown, when the user places the carrier 130 onto the seat plate 1210', the engaging member 13131 of the carrier 130 moves downward and is engaged in the recessed portion 1212' by the locking part 12221'a of the front locking member 12221'. Simultaneously, the bottom surface of the carrier 130 presses down on the actuation button 1251, compressing the reset member 1255. The latching part 1252 and the elastic member 1253 connecting the actuation button 1251 and the latching part 1252 move downward as the actuation button 1251 is pressed down. At this time, the holding mechanism is in a ready state.

[0693] When it is necessary to remove the vehicle 130 from the seat plate 1210', such as FIG. 16A As shown, the user can operate (e.g., press) the release operation member 1221'. The front locking member 12221' connected to the release operation member 1221' moves with the release operation member 1221', thereby causing the retaining hook 12221'b of the front locking member 12221' to move toward the retaining mechanism 1250 and hook the latch portion 1252. More specifically, as the retaining hook 12221'b moves toward the retaining mechanism 1250, the front end of the retaining hook 12221'b (e.g., through its chamfer) causes the latching portion 1252 to move upward relative to the touch button 1251 against the force of the elastic member 1253 (i.e., the latching portion 1252 compresses the elastic member 1253 and moves closer to the touch button 1251) until the hook-shaped portion of the retaining hook 12221'b passes over the latching portion 1252, and the latching portion 1252 moves downward under the action of the elastic member 1253 and is hooked by the retaining hook 12221'b. At this time, the holding mechanism 1250 is in the holding state, and the latching part 1252 is maintained in the state of being engaged by the holding hook 12221'b under the downward pressure applied by the carrier 130 and the action of the elastic member 1253, thereby keeping the release operation member 1221' in the release position, and the engaging part 13131 of the carrier 130 is not blocked by the locking part 12221'a (that is, the carrier 130 continues to be in a state that can be moved).

[0694] Next, when the carrier 130 is removed, the trigger button 1251 protrudes again from above the seat plate 1210' under the action of the reset member 1255. The latch 1252 moves upward with the trigger button 1251 and separates from the retaining hook 12221'b of the front locking member 12221'. The release operation member 1221' returns to its original position. FIG. 16D The lock position is shown.

[0695] Reference FIG. 16D It shows the structure of the retaining mechanism 1250 according to this disclosure.

[0696] like FIG. 16DAs shown, the touch button 1251 is arranged in the slide 1214' arranged inside the seat plate 1210', so as to be able to move up and down along the slide 1214'. Symmetrical notches 1215' are arranged on the wall of the slide 1214', so that the holding hook 12221'b can extend into the notches 1215' when the holding mechanism 1250 moves, to achieve engagement.

[0697] In addition, as FIG. 16B shown, when the carrier 130 (in combination with FIG. 16C and FIG. 16D shown) is installed on the seat plate 1210', the distance of the inward movement of the locking part 12221'a is L11; the distance required for the holding hook 12221'b to engage with the buckle part 1252 (i.e. the distance from the holding hook 12221'b to the farthest end of the buckle part 1252) is L12; and the distance of the pressing of the release operation member 1221' for release is L13. In an embodiment, L11 FIG. 16B (not shown in the drawings, please refer to FIG. 17A-17D ) is locked on the seat plate 1210', the holding hook 12221'b will not hook the buckle part 1252, and only when the release operation member 1221' is pressed, the holding hook 12221'b will hook the buckle part 1252.

[0698] The seat assembly of the present disclosure provides a wheel-type moving device that is convenient to operate and simple in structure, by arranging a linkage assembly between the release operation members, and a linkage between the front locking member and the rear locking member, and by further arranging a holding mechanism, so that the user can simultaneously release the front locking member and the rear locking member by operating only one of the release operation members, thereby enabling the user to conveniently (e.g. with one hand) move the carrier away from the frame, which provides a better user experience for the user.

[0699] Optionally, by arranging a support frame with damping effect on the seat assembly, so that when the frame moves, it can provide cushioning support for the carrier installed on the frame and the infant therein, thereby providing a more comfortable and safer wheel-type moving device. In addition, by using limiting structures such as limiting fingers, limiting blocks and / or limiting members in combination, the cushioning displacement of the support frame can be limited within a certain range, so that the carrier arranged on the frame by the seat assembly moves more smoothly. The present disclosure is not limited to the above installation structure, for example FIG. 17A-17D is also shown in the wheel-type moving device 11A with another installation structure and the seat assembly 120A installed thereon.

[0700] Reference is made to FIG. 17A , FIG. 17B and FIG. 17CThe images show perspective views of a wheeled mobility device 11A according to an embodiment of the present disclosure from different angles. FIG. 17D A front view of the wheeled mobility device 11A is shown, and FIG. 17A-17D A side view of the wheeled mobility device 11A is shown.

[0701] like FIG. 2 As shown, the wheeled mobility device 11A includes a frame 110A, a mounting bracket 120A, and a carrier (not shown) mounted on the mounting bracket 120A. The frame 110A includes a front support rod 1110A, a rear support rod 1120A, and an upper support rod 1130A, which are pivotally connected to each other, allowing them to fold relative to each other. Specifically, the frame 110A has the same characteristics as in the aforementioned embodiments (e.g., ...). FIG. 18A-18D Similar to the structure shown, it will not be described further. The card holder assembly 120A is mounted on the frame 110A and can lock or unlock objects to securely place objects (e.g., vehicles, not shown) on the card holder assembly 120A, thereby improving the safety of the objects during movement. By operating the card holder assembly 120A, the user can easily install or remove objects from the frame 110A. The following will combine... FIG. 18A-18F Let me describe the card slot assembly 120A in detail.

[0702] refer to FIG. 18A , FIG. 18B A perspective view of the card slot assembly 120A is shown; FIG. 18C and FIG. 18D The card holder assembly 120A with the seat plate 1210A removed is shown to show the support structure 1240A and the locking mechanism 1220A located within the seat plate 1210A; FIG. 18A Show along FIG. 18E The cross-sectional view of the card holder assembly 120A taken by line XX is shown; FIG. 18D Show FIG. 18F A partial enlarged view of section J is shown, in which the release mechanism 1221A is in the locked position; and FIG. 18E Show FIG. 18A The view shown is of the release mechanism 1221A in the release position.

[0703] like FIG. 18B and FIG. 18A As shown, the card holder assembly 120A includes a base plate 1210A and a locking mechanism 1220A. FIG. 10B The release mechanism 1221A and the support structure 1240A are shown only, with the middle part obscured by the seat plate 1210A.

[0704] In one example, the base plate 1210A may have a hollow structure (with) FIG. 18AThe seat plate 1210 in the illustrated embodiment is different. Specifically, as shown... FIG. 9A As shown, the seat plate 1210A can have a ring-shaped structure (i.e., the middle area of ​​the seat plate 1210A is hollow). When the frame 110A and the cradle assembly 120A are folded together, the user can lift or move the entire frame structure by grasping the hollow structure of the seat plate 1210A. In other words, the seat plate 1210A in this example may not have such a structure. FIG. 18A The handle 1211 shown allows for easy movement of the entire folded frame 110A.

[0705] In addition, such as FIG. 18A-18C As shown, the seat plate 1210A may have a first extension 1211A, which extends outward from one end (e.g., the middle of the rear end) of the seat plate 1210A to provide a larger support surface (i.e., a first abutment surface), thereby providing more stable support for the vehicle (not shown in the figure) mounted thereon. The seat plate 1210A may also have a second extension 1212A extending from the other end (e.g., the front end) of the seat plate 1210A to provide an additional support surface (i.e., a second abutment surface), thereby helping to improve the stability of the vehicle on the frame 110A and helping to maintain balance after the vehicle is engaged with the entire frame 110A. Optionally, the first abutment surface and the second abutment surface may be located at opposite ends of the seat plate 1210A. In one example, the first extension 1211A and / or the second extension 1212A may also be configured as a carrying handle to facilitate moving the frame 110A in its unfolded or folded state.

[0706] Combination FIG. 3A-3C As shown, the support structure 1240A may include two support frames 1241A, respectively disposed on both sides of the seat plate 1210A, for example, symmetrically disposed on both sides of the seat plate 1210A. FIG. 18C Unlike other embodiments, the support frame 1241A in this embodiment does not have a shock-absorbing structure. Specifically, each support frame 1241A may include a longitudinal rod 12411A, a first support rod 12412A, and a second support rod 12413A. The longitudinal rod 12411A is disposed below the seat plate 1210A and fixedly connected to the seat plate 1210A. One end of each of the first support rod 12412A and the second support rod 12413A is connected to the longitudinal rod 12411A, and their other ends are connected to each other, so that the first support rod 12412A, the second support rod 12413A, and the longitudinal rod 12411A form a triangular structure to stably support the seat plate 1210A and the object above it. Optionally, the connection point between the second support rod 12413A and the longitudinal rod 12411A is located in the middle section of the seat plate 1210A along its longitudinal direction D15.

[0707] In one example, the support structure 1240A further comprises a first connecting rod 1242A. The first connecting rod 1242A is a symmetrically arranged cross rod or U-shaped rod. Specifically, the first connecting rod 1242A can be connected between the longitudinal rods 12411A on both sides. Alternatively or additionally, as shown in FIG. 17B , the first connecting rod 1242A is integrally formed with the longitudinal rods 12411A on both sides, i.e. the first connecting rod 1242A is the same rod as the longitudinal rods 12411A.

[0708] In combination FIG. 18A-18C , FIG. 17B , it can be seen that the cradle assembly 120A is pivotably connected and mounted to the frame 110A via its support structure 1240A, wherein the seat plate 1210A and the locking mechanism 1220A of the cradle assembly 120A are fixedly mounted to the support structure 1240A, and the seat plate 1210A provides a generally horizontal support surface for placing an object (in this example, a carrier). The support structure 1240A further comprises a first connecting member 1244A and a second connecting member 1245A, which are respectively pivotably connected to the frame 110A, so that the cradle assembly 120A can be folded together with the frame 110A when the frame 110A is folded.

[0709] Specifically, as shown in FIG. 18B and FIG. 18A , one end of each of the first connecting member 1244A and the second connecting member 1245A is pivotably connected to one end of the first strut 12412A (i.e. the end connected to the second strut 12413A), and the other end of each of the first connecting member 1244A and the second connecting member 1245A, as well as the other end of the first strut 12412A, are pivotably connected to different positions on the frame 110A that can pivot relative to each other. For example, the other end of the first connecting member 1244A is pivotably connected to the upper support rod 1130A of the frame 110A, the other end of the second connecting member 1245A is pivotably connected to the rear support rod 1120A of the frame 110A, and the other end of the first strut 12412A is pivotably connected to the front support rod 1110A of the frame 110A, so that the support structure 1240A, together with the entire cradle assembly 120A, can be pivoted when the frame 110A is pivoted, thereby achieving overall folding.

[0710] Referring to FIG. 18B , FIG. 18D and FIG. 10AA locking mechanism 1220A is mounted within a base plate 1210A for locking and releasing an object located on the base plate 1210A. The locking mechanism 1220A includes at least one release actuating member 1221A and at least one locking member 1222A. The release actuating member 1221A is disposed within the base plate 1210A and is movable relative to the base plate 1210A between a locked position and a released position. The release actuating member 1221A differs from that in the aforementioned embodiment in that: FIG. 10B and FIG. 18A As shown, the release mechanism 1221 protrudes from the side of the base plate 1210, and the user can release the lock by pressing the release mechanism 1221 from the side of the base plate 1210; in this embodiment, as FIG. 18D and FIG. 18D As shown, the release mechanism 1221A protrudes from above the base plate 1210A, and the user can release the lock by pressing down on the release mechanism 1221A.

[0711] like FIG. 18D As shown, the release operation member 1221A is slidably connected to the locking member 1222A, so that the locking member 1222A can move accordingly as the release operation member 1221A moves. Specifically, when the release operation member 1221A is in the position shown... FIG. 18A In the locked position, at least a portion of the release mechanism 1221A protrudes from the base plate 1210A, locking an object placed on the base plate 1210A. When the release mechanism 1221A is pressed and moved from the locked position to the unlocked position, the locking member 1222A moves along with the release mechanism 1221A, thereby releasing the object on the base plate 1210A. In one example, as the release mechanism 1221A moves vertically, the locking member 1222A can move in a generally horizontal direction to achieve unlocking. That is, the direction of movement of the release mechanism 1221A can be generally perpendicular to the direction of movement of the locking member 1222A.

[0712] Furthermore, at least one locking element 1222A can be multiple locking elements 1222A. The connection relationship between the multiple locking elements 1222A (e.g., linkage components, linkage parts, etc.) is similar to that in the aforementioned embodiments, and therefore will not be described in detail here. The specific structure of the locking element 1222A and its specific linkage method with the unlocking operation element 1221A, especially the differences from the locking element 1222 in the aforementioned embodiments, will be described in detail below.

[0713] like FIG. 18D and FIG. 18D-18FAs shown, the locking member 1222A is provided with a locking portion 1222Aa, and the seat plate 1210A is provided with an opening at a position corresponding to the locking portion 1222Aa, so that the locking portion 1222Aa can extend out of the opening of the seat plate 1210A to lock an object placed on the seat plate 1210A. As similar to the foregoing embodiments, the seat plate 1210A can also be correspondingly provided with a recess, an inclined surface, etc., which will not be described herein.

[0714] In the present embodiment, as shown in FIG. 18E The locking member 1222A can have a first portion 12221A and a second portion 12222A fixedly connected to each other. The second portion 12222A is connected below the first portion 12221A and extends from one end of the first portion 12221A to the release operation member 1221A. The end of the first portion 12221A is spaced apart from the release operation member 1221A by a distance. The locking portion 1222Aa is arranged at the end of the first portion 12221A (i.e., the end close to the release operation member 1221A), and the second portion 12222A is slidably connected to the release operation member 1221A at the end close to the release operation member 1221A. In an example, the first portion 12221A and the second portion 12222A can be separate components and fixedly connected together by bolts or the like. Alternatively or additionally, the first portion 12221A and the second portion 12222A can be integrally formed.

[0715] Correspondingly, as shown in FIG. 18F and FIG. 18E The release operation member 1221A can also be fixedly provided with a driving pin 12211A, and the second portion 12222A of the locking member 1222A is provided with a slanted hole 1222Ab at the end close to the release operation member 1221A, and the driving pin 12211A of the release operation member 1221A can slide in the slanted hole 1222Ab, i.e., the driving pin 12211A can slide relative to the slanted hole 1222Ab along with the operation of the release operation member 1221A. In an example, as shown in FIG. 18F and FIG. 18E The slanted hole 1222Ab can be arranged to be inclined downward from inside to outside.

[0716] Further referring to FIG. 18F and FIG. 18E wherein FIG. 18F shows a state where the release operation member 1221A is in the locked position, FIG. 18E shows a state where the release operation member 1221A is in the released position. When the release operation member 1221A is operated, the driving pin 12211A can slide relative to the slanted hole 1222Ab along with the movement of the release operation member 1221A to drive the locking member 1222A to move from the locked position to the released position. For example, referring toFIG. 18F and FIG. 18E When the lock needs to be released, the user can press down the release operating member 1221A, and the release operating member 1221A moves from the locking position (see FIG. 18F ) to the release position (see FIG. 18D ), so that the driving pin 12211A fixed to the release operating member 1221A moves downward, i.e., the downward movement of the driving pin 12211A of the release operating member 1221A relatively slides with the inclined hole 1222Ab of the locking member 1222A, forcing the locking member 1222A to move in a direction perpendicular or substantially perpendicular to the movement direction of the driving pin 12211A (for example, the transverse direction D16 of the cartridge assembly 120A), so that the locking member 1222A moves to its release position (for example, in this embodiment, the locking members 1222A on the same side move towards each other), and the locking part 1222Aa of the locking member 1222A protruding from the seat plate 1210A retracts into the seat plate 1210A to release the object provided on the seat plate 1210A.

[0717] In addition, the locking mechanism 1220 of the present embodiment can also be provided with elastic device 1224A to provide a force to make the release operating member 1221A be in or return to the locking position. In an example, as shown in FIG. 18D-18F , the elastic device 1224A can be arranged between the two locking members 1222A on the same side, tending to make the two locking members 1222A move away from each other. For reference FIG. 19A When the release operating member 1221A is released, the locking member 1222A can move to its locking position under the action of the elastic device 1224A, and the release operating member 1221A moves upward to its locking position under the action of the force of the inclined hole 1222Ab relative to the driving pin 12211A.

[0718] In a second aspect of the present disclosure, a wheeled mobile device 21 is also provided.

[0719] Referring to FIG. 19A , FIG. 19A shows a perspective view of the wheeled mobile device 21 according to the second aspect of the present disclosure.

[0720] As FIG. 19BAs shown, the wheeled mobility device 21 can include a frame 2100, a mount assembly 2200, and a carrier 2300. The mount assembly 2200 can be mounted on the frame 2100, and the carrier 2300 can be secured to the frame 2100 via the mount assembly 2200 so as to move together with the frame 2100. In an embodiment, the carrier 2300 can include a box 2310 (which can also be referred to as a "carrying portion") providing a receiving space (i.e., a carrying space) for carrying an infant or a pet, and a support device 2320 mounted on the box 2310 to support the box 2310 and capable of being engaged with the mount assembly 2200 so as to enable the carrier 2300 to be detachably mounted on the frame 2100 via the support device 2320.

[0721] The frame 2100 and the mount assembly 2200 of the wheeled mobility device 21 and the connection relationship therebetween will be described in detail hereinafter.

[0722] First, reference is made to FIG. 19C and FIG. 19B , FIG. 19C showing a perspective view of the frame 2100 according to the second aspect of the present disclosure, and FIG. 19B showing FIG. 19B a perspective view of the frame 2100 from another angle.

[0723] The frame 2100 of the present disclosure can include a front support rod 2110, a rear support rod 2120, and an upper support rod 2130, wherein the front support rod 2110 is connected with the front wheel 2181, the rear support rod 2120 is connected with the rear wheel 2182, and the upper support rod 2130 is connected with the handrail 2170.

[0724] In an embodiment, as FIG. 19C and FIG. 19BAs shown, one end of the front support rod 2110, one end of the rear support rod 2120 and one end of the upper support rod 2130 are pivotally connected to each other at the first pivot portion A2, so that the front support rod 2110, the rear support rod 2120 and the upper support rod 2130 can be folded relative to each other through the first pivot portion A2. Specifically, the front support rod 2110 can have a U-shaped structure, the rear support rod 2120 can be formed by two parallel rod members fixedly connected by a cross rod, and the two ends of the front support rod 2110 are respectively pivotally connected to one end of the two rod members of the rear support rod 2120 at the first pivot portion A2. At least one front wheel 2181 is connected to the lower side of the front support rod 2110, and the other end of the two rod members of the rear support rod 2120 is respectively connected to a corresponding rear wheel 2182. The armrest 2170 is located at the other end (i.e. the upper end) of the upper support rod 2130 and is pivotally connected to the upper support rod 2130 through the second pivot portion B2. The present disclosure is not limited to the above structure, and the front support rod 2110 can also have a V-shaped or I-shaped structure, and the rear support rod 2120 can also be provided in a one-piece U-shaped structure, etc.

[0725] In an example, as shown in FIG. 19A , the size of the rear wheel 2182 can be larger than the size of the front wheel 2181, so that the overall structure of the wheeled moving device 21 is more stable.

[0726] In addition, as can be seen from FIG. 19B and FIG. 19B , the frame 2100 is also provided with a connecting assembly for mounting the card holder assembly 2200 on the frame 2100 (which will be described in detail below), which is pivotally connected to the frame 2100, so that the card holder assembly 2200 can be pivoted through the connecting assembly as the frame 2100 is folded. The connecting assembly can also serve as a support structure for the card holder assembly 2200, for example, as the "support structure 1240" and / or "support structure 1240A" described in the first aspect of the present disclosure.

[0727] In an embodiment, as shown in FIG. 19C and FIG. 19B , the connecting assembly can include a first coupling member 2140, an auxiliary support member 2150 and a linkage member 2160.

[0728] As shown in FIG. 19A-19CAs shown, one end of the first link 2140 is pivotably connected to the front support rod 2110 at a first pivot point O21. The auxiliary support 2150 is pivotably connected to the other end of the first link 2140 at a second pivot point O22, and is pivotably connected to the rear support rod 2120 at a third pivot point O23. One end of the link 2160 is pivotably connected to the upper support rod 2130 at a fourth pivot point O24, and the other end is pivotably connected to the auxiliary support 2150 at a fifth pivot point O25. Through the connections at the above-mentioned pivot points, the auxiliary support 2150 can be pivoted when the frame 2100 is folded. The fifth pivot point O25 is between the second pivot point O22 and the third pivot point O23, i.e. the second pivot point O22 is between the first pivot point O21 and the fifth pivot point O25. Alternatively, the fifth pivot point O25 can coincide with the second pivot point O22.

[0729] Further reference is made to FIG. 19B The link 2160 can have an approximately S-shaped structure, so as to avoid interference with the rear support rod 2120, the seat plate 2200 or other components when the frame 2100 is folded, i.e. to form a structure for avoiding interference. Specifically, the approximately S-shaped structure has a first section 2161, a second section 2162 and a third section 2163 in sequence. The second section 2162 is substantially perpendicular to the first section 2161, and the third section 2163 is substantially perpendicular to the second section 2162. When the frame 2100 is unfolded, the first section 2161 substantially overlaps the upper support rod 2130. The present disclosure is not limited thereto, and the link 2160 can also be designed in other shapes or structures that can avoid interference with other components when folded. In addition, the link 2160 can also be provided in the form of a straight rod, by adjusting other components so that the plurality of rods or components do not interfere with each other when folded.

[0730] In a specific example, two first links 2140 can be provided, one end of each of which is connected to the front support rod 2110 on the side. The auxiliary support 2150 can have a substantially U-shaped structure, and the two ends of the auxiliary support 2150 are connected to the other end of the corresponding first link 2140. In addition, the auxiliary support 2150 can also be provided with two separate straight rods, which are connected between the first link 2140 and the rear support rod 2120 on one side of the frame 2100, but the present disclosure is not limited thereto.

[0731] In an embodiment, as shown in FIG. 20 When the frame 2100 is unfolded, the first link 2140 and the auxiliary support 2150 are horizontally arranged, the first pivot point O21, the second pivot point O22, the third pivot point O23 and the fifth pivot point O25 are on the same horizontal plane, and optionally, these pivot points are substantially in a straight line.

[0732] In addition, with reference to FIG. 21 and FIG. 20 , FIG. 21 a perspective view of a card seat assembly 2200 according to the present disclosure is shown, and FIG. 20 a perspective view of the card seat assembly 2200 is shown after the removal of a seat plate 2210. FIG. 20 As shown in

[0733] and FIG. 21 , the card seat assembly 2200 includes the seat plate 2210 and a locking mechanism 2220 for locking the carrier 2300 FIG. 20 (not shown in FIG. 21 and FIG. 19A , see FIG. 20 ) on the seat plate 2210. Among them, the card seat assembly 2200 can have multiple clamping point positions to support and position the carrier 2300, thereby improving the connection stability between the carrier 2300 and the card seat assembly 2200. For example, as shown in FIG. 20 , multiple clamping point positions can be symmetrically arranged on the card seat assembly 2200 along the longitudinal center line M2 of the card seat assembly 2200, so that the carrier is more stably locked on the seat plate 2210 of the card seat assembly 2200. Alternatively, four clamping point positions can be symmetrically arranged on the card seat assembly 2200.

[0734] In addition, as shown in FIG. 19A , the seat plate 2210 can have a first extension 2211. The first extension 2211 extends from one end (for example, the rear end, that is, in combination with FIG. 19B and FIG. 20 , the end close to the rear wheel 2182) of the seat plate 2210. More specifically, the first extension 2211 can extend a certain distance from the middle of the rear end of the seat plate 2210 to the rear, so as to provide a larger support surface to more stably support the carrier 2300 FIG. 19B (not shown in FIG. 20 ) arranged above it. It should be noted that the "rear end" described herein is the rear side relative to the frame 2100 (for example, the rear wheel 2182 is located on the rear side of the frame 2100), that is, as shown in FIG. 20 , the left side is the front end of the seat plate 2210, and the right side is the rear end of the seat plate 2210. In addition, the first extension 2211 can also be provided in the form of a handle for easy pulling and moving after folding. In an embodiment, the seat plate 2210 can also be provided in a hollow form, for example FIG. 31The annular structure (i.e. the middle region of the seat plate 2210 is hollowed out) allows the entire frame structure to be gripped, lifted or moved by the hollowed-out design of the seat plate 2210 when the frame 2100 is folded together with the holder assembly 2200 (see, for example, FIG. 20 ).

[0735] Alternatively or additionally, the seat plate 2210 can also have a second extension 2212 extending from the front end of the seat plate 2210 (i.e. the end close to the front wheel 2181) to provide an additional support surface, thereby helping to improve the stability of the carrier on the frame 2100 and helping the carrier to remain balanced after being engaged to the entire frame 2100.

[0736] In an embodiment, as shown in FIG. 21 and FIG. 19A , the holder assembly 2200 can be arranged on the seat plate support 2230 and connected to the frame 2100 through the seat plate support 2230 (see FIG. 21 ). In an embodiment, as shown in FIG. 22 , the seat plate support 2230 can have a U-shaped structure, wherein the locking structure 2220 of the holder assembly 2200 is arranged between the two ends of the U-shaped structure and / or on the transverse section of the U-shaped structure (i.e. between the two longitudinal sections), but the present disclosure is not limited thereto. The connection between the seat plate support 2230 and the frame 2100 will be described in detail below in connection with FIG. 23 and FIG. 22 .

[0737] Referring to FIG. 23 and FIG. 22 , FIG. 19B show a perspective view of the frame 2100 and the seat plate support 2230 mounted on the frame 2100 as shown in FIG. 23 , and FIG. 22 show another angle of the perspective view of the frame 2100 and the seat plate support 2230 as shown in FIG. 22 .

[0738] In an embodiment of the present disclosure, as shown in FIG. 23 and FIG. 22 , the auxiliary support 2150 is arranged outside the seat plate support 2230 and connected with the seat plate support 2230, so that the seat plate support 2230 can move synchronously with the auxiliary support 2150, thereby driving the holder assembly 2200 mounted on the seat plate support 2230 (not shown in FIG. 23 and FIG. 24 , see FIG. 24-27) synchronous movement to achieve the synchronous folding of the seat assembly 2200 and the frame 2100. In this embodiment, the other end of the first link 2140 is interposed between the seat plate support 2230 and the auxiliary support 2150. For example, the auxiliary support 2150 and the seat plate support 2230 are connected to each other at the second pivot point O22 by the rod of the first link 2140, and are disposed on both sides of the first link 2140, so that the auxiliary support 2150 and the seat plate support 2230 can be pivoted synchronously relative to the first link 2140. In addition, the other end of the connecting member 2160 (i.e., the end connected to the auxiliary support 2150) is interposed between the seat plate support 2230 and the auxiliary support 2150. Alternatively, the auxiliary support 2150 can be fixedly connected to the seat plate support 2230, or the two can be integrally formed. In another embodiment, the auxiliary support 2150 and the seat plate support 2230 can be connected to the seat assembly 2200.

[0739] It should be noted that in the above embodiment, the fixedly connected auxiliary support 2150 and the seat plate support 2230 can be regarded as the second link of the connecting assembly in a combined form. However, it should be understood that the second link can also include only the seat plate support (not shown). For example, in an embodiment in which the second link includes only the seat plate support, the seat plate support can have a U-shaped structure and be pivotally connected to the first link 2140, the connecting member 2160 and the rear support rod 2120, respectively, so as to be pivoted as the frame 2100 is folded, and in turn, the seat assembly 2200 fixed to the seat plate support is pivoted.

[0740] Further referring to FIG. 24 , FIG. 25 Fig. 1 shows a perspective view of the frame 2100 of the present disclosure and the seat assembly 2200 mounted on the frame 2100, FIG. 24 Fig. 2 shows FIG. 26 Fig. 3 shows a perspective view of the frame 2100 and the seat assembly 2200 from another angle, FIG. 19A Fig. 4 shows FIG. 27 Fig. 5 shows a side view of the wheeled mobile device 21, and FIG. 26 Fig. 6 shows FIG. 24 Fig. 7 shows a front view of the wheeled mobile device 21 after the removal of the carrier 2300.

[0741] As shown in Figs. 1 and 2, FIG. 25 and FIG. 26 When the frame 2100 is unfolded, the seat assembly 2200 of the present disclosure can be positioned at a lower position of the frame 2100. For example, compared with the seat assembly 120 and the seat assembly 120A according to the first aspect of the present disclosure, the seat assembly 2200 can be at a lower position.

[0742] In particular, in an embodiment, the seat assembly 2200 is positioned at a height lower than the first pivot portion A2, e.g., can be disposed proximate to or at substantially the same height as the lower end of the front support bar 2110. More particularly, in combination with the above-mentioned FIG. 19A As shown, the height H1 of the position where the seat assembly 2200 is disposed can be less than the median of the overall height H2 of the frame 2100, and in an example, the height H1 can be close to or even less than one third of the overall height H2 of the frame 2100. With such arrangement, i.e., the seat assembly 2200 is disposed at a lower position of the frame 2100, the user can more conveniently and labor-savingly place and position the carrier 2300 (see FIG. 24 ) on the seat assembly 2200, which improves the convenience of use and user experience; and moreover, the frame 2100 can be adapted to more different sizes (e.g., different heights) of the carrier 2300, which improves the adaptability of use. It is to be noted that the seat assembly 2200 can also be disposed on the frame 2100 with the support structure 1240A described in the first aspect of the present disclosure and positioned at a height lower than the first pivot portion A2, and the present disclosure is not limited thereto.

[0743] Further, as shown in FIG. 25 and FIG. 26 , the center of gravity G of the seat assembly 2200 disposed at the lower position can be offset towards the rear wheels 2182 relative to the first pivot portion A2, which helps to improve the stability of the frame 2100. In detail, after the carrier 2300 (see FIG. 26 ) is installed on the frame 2100, because the center of gravity G of the seat assembly 2200 has been moved backwards, the frame 2100 is less likely to be overturned due to the pet in the carrier 2300 leaning towards the front end of the carrier 2300 (at this time, the weight of the pet is concentrated at the front end of the carrier 2300), which helps to improve the stability of the overall structure of the wheeled mobile device 21. For example, in an embodiment, the center of gravity of the seat assembly 2200 can be proximate to or located at the plane formed by the pair of rear support bars 2120.

[0744] As shown in FIG. 27 and FIG. 28-31 , when the frame 2100 is unfolded, the horizontal distance L22 between the rear wheels 2182 and the distal end of the frame 2100 (e.g., at the armrest 2170) is less than the horizontal distance L21 between the front wheels 2181 and the rear wheels 2182. In addition, the width W23 between the two side support bars can be between the distance W21 between the two front wheels 2181 and the distance W22 between the two rear wheels 2182.

[0745] Referring to FIG. 28 , which schematically shows the folding process of the frame 2100 and the seat assembly 2200, wherein, FIG. 24 shows FIG. 29a side view of the frame 2100 and the seat assembly 2200 shown when fully unfolded, FIG. 28 shown FIG. 30 a side view of the frame 2100 and the seat assembly 2200 shown when halfway through folding, FIG. 28 shown FIG. 31 a side view of the frame 2100 and the seat assembly 2200 shown after fully folding, and FIG. 30 shown FIG. 28-30 a front view of the frame 2100 and the seat assembly 2200 shown.

[0746] in conjunction with FIG. 29 As shown, the frame 2100 of the present disclosure is foldable to facilitate portability and storage. Specifically, the armrests 2170 of the frame 2100 are pivotably connected to the upper support rod 2130 via the second pivot portion B2 and are foldable relative to the upper support rod 2130. The front support rod 2110, the rear support rod 2120, and the upper support rod 2130 are pivotally connected to the first pivot portion A2 and are foldable relative to each other. Furthermore, the seat assembly 2200 is also pivotable via the connecting assembly when the frame 2100 is folded. Specifically, in one embodiment, when the front support rod 2110, the rear support rod 2120, and the upper support rod 2130 are folded relative to each other, the linkage 2160 and the auxiliary support 2150 are pivoted, thereby causing the seat plate support 2230 fixedly connected to the auxiliary support 2150 and the seat assembly 2200 mounted on the seat plate support 2230 to also pivot when the frame 2100 is folded.

[0747] In one specific embodiment, when the frame 2100 is folded, the front support rod 2110, the rear support rod 2120, and the upper support rod 2130 are moved closer to each other, and the connecting assembly causes the rear end of the seat assembly 2200 (e.g., the end where the first extension portion 2211 is provided, i.e., the end of the seat assembly 2200 closer to the rear wheel 2182 or the rear support rod 2120) to pivot toward the first pivot portion A2. More specifically, as shown in FIG. 30 and FIG. 29 As the front support rod 2110, the rear support rod 2120, and the upper support rod 2130 are folded relative to each other, the upper support rod 2130 causes the linkage 2160 to pivot, the front support rod 2110 causes the first coupling 2140 to pivot, the auxiliary support 2150 pivots toward the first pivot portion A2 under the action of the first coupling 2140 and the linkage 2160, and the seat plate support 2230 connected to the auxiliary support 2150 is caused to pivot, such that the longitudinal rear end of the seat plate support 2230 and the seat assembly 2200 provided thereon pivot toward the first pivot portion A2 (from FIG. 30As can be seen from the middle view, the card holder assembly 2200 is folded in a manner that its upper surface is pivoted towards the front side of the frame 2100, and is accommodated in the overall structure of the frame 2100 as the frame 2100 is folded, as shown in the fully folded state. FIG. 30 As can be seen from the middle view, the card holder assembly 2200 is folded in a manner that its upper surface is pivoted towards the front side of the frame 2100, and is accommodated in the overall structure of the frame 2100 as the frame 2100 is folded, as shown in the fully folded state.

[0748] Further referring to FIG. 32A When the frame 2100 is fully folded, i.e., the front support rod 2110, the rear support rod 2120, the upper support rod 2130, and the armrest 2170 are folded to the closest positions relative to each other, the card holder assembly 2200 is accommodated between the upper support rod 2130 and the front support rod 2110 and the rear support rod 2120 as it is pivoted.

[0749] It should be noted that, without affecting the structural integrity, the card holder assembly 120, 120', 120A of the first aspect of the present disclosure and part or all of the structure of the card holder assembly 2200 in the second aspect of the present disclosure can be combined or replaced.

[0750] The third aspect of the present disclosure relates to a carrier, in particular a carrier with relatively light weight and relatively high structural strength. For the convenience of understanding, similar structures in different embodiments below have similar reference numerals, for example, the reference numerals of the carriers in the first embodiment to the seventh embodiment are "3100" to "3700", respectively.

[0751] Please refer to FIG. 32B and FIG. 32A , FIG. 32B and FIG. 32A The appearance schematic diagram of the carrier 3100 of the first embodiment of the third aspect of the present disclosure from different viewing angles. As shown in FIG. 32B and FIG. 32B The carrier 3100 comprises a box body 3110 and a support device 3120, the box body 3110 (which can also be referred to as "carrying part") comprises a bottom 3111 (i.e., box base) and a peripheral wall 3112 connected to the bottom 3111, the bottom 3111 and the peripheral wall 3112 define a containing space 3113 (i.e., carrying space for carrying children or animals), wherein the upper surface of the bottom 3111 is located in the containing space 3113, and the lower surface of the bottom 3111 constitutes the bottom surface of the box body 3110. In this embodiment, the containing space 3113 can be used to contain children, i.e., the carrier of this embodiment is a carrier for children, but the present disclosure is not limited to this embodiment. For example, in another embodiment, the containing space can be used to contain pets. In addition, in this embodiment, the box body 3110 can be made of foamed polypropylene (EPP), foamed polyethylene (EPE), foamed ethylene (EPO), etc. foamed material, and the support device can be made of metal or other materials with relatively high rigidity, but the present disclosure is not limited to this embodiment.

[0752] Please refer to FIG. 32C With FIG. 32C , FIG. 32B is a partial exploded view of the carrier 3100 of the first embodiment of the third aspect of the present disclosure. As shown in FIG. 32C With FIG. 32D , the support device 3120 includes a first support 3121, two second supports 3122, a third support 3123, and a fixing assembly 3124 connecting the box body 3110 and the third support 3123. The first support 3121 is combined with the box body 3110 and is arranged around the peripheral wall 3112 of the box body 3110. The two second supports 3122 are connected to the first support 3121 and are arranged separately from each other along the longitudinal axis direction D31 of the box body 3110 (on both sides of the center line of the long side of the box body 3110, respectively). Each second support 3122 is combined with the box body 3110 and extends from one side of the peripheral wall 3112 of the box body 3110 to the other side of the peripheral wall 3112 of the box body 3110 along the transverse axis direction D32 of the box body 3110 through the bottom 3111 of the box body 3110. In this way, by being arranged on the peripheral wall 3112 at intervals by the two second supports 3122, stable support of the box body 3110 can be provided, and the impact resistance of the box body 3110 can be improved. The third support 3123 is arranged on one side of the bottom 3111 of the box body 3110 and is spaced apart from the bottom 3111 of the box body 3110 (in particular, the lower surface of the bottom 3111 of the box body 3110, i.e., the bottom surface of the box body 3110) by the fixing assembly 3124. The first support 3121 and the third support 3123 are arranged substantially horizontally, and the first support 3121 and the third support 3123 are arranged vertically on the top and bottom sides of the bottom 3111 of the box body 3110. In this embodiment, the third support 3123 and the bottom 3111 of the box body 3110 can not be in contact with each other at all, but the present disclosure is not limited to this embodiment.

[0753] Please refer to FIG. 32E With FIG. 32D , FIG. 32E is a schematic view of the carrier 3100 of the first embodiment of the third aspect of the present disclosure when installed on the base 3B0, FIG. 32D is a partial structural schematic view of the carrier 3100 of the first embodiment of the third aspect of the present disclosure when installed on the base 3B0. As shown in FIG. 32E With FIG. 32E , the third support 3123 is used to cooperate with the clamping structure 3B1 of the base 3B0, so that the carrier 3100 can be installed on the base 3B0 through the cooperation of the third support 3123 and the clamping structure 3B1. Specifically, as shown in FIG. 32EAs shown, in this embodiment, the base 3B0 can be provided with four engaging portions 3B11 to form four engaging points with the engaging member 31231, wherein the four engaging portions 3B11 are arranged in pairs, i.e. on opposite sides of the base 3B0 along the horizontal axis direction D32, so that the four engaging points are also arranged in pairs and are located on the two long sides of the engaging member 31231, respectively. In another embodiment, in addition to the ring-shaped structure member, the engaging member 31231 can also be a single engaging rod or two parallel engaging rods, and the base 3B0 has at least one pair of engaging portions to fix the engaging member 31231 on one side or both sides.

[0754] In addition, when the carrier 3100 is installed on the base 3B0, because the carrier 3100 has an elongated structure, the center of gravity of the carrier 3100 is located on the side above the base 3B0 relative to the base 3B0. Therefore, when the user wants to release the installation between the carrier 3100 and the base 3B0, in addition to operating the release button, the carrier 3100 also needs to be lifted to avoid the situation that the hook cannot be released smoothly, so as to ensure that the carrier 3100 is unloaded while the user holds the handle, avoiding the situation that the carrier 3100 tilts instantaneously due to the offset center of gravity relative to the base 3B0.

[0755] However, the structure of the carrier of the present disclosure is not limited to this embodiment. For example, in another embodiment, the support device can include one second support arranged centrally. Alternatively, the support device can include more than two second supports, thereby providing better support for the box. Alternatively, in another embodiment, the third support and the fixing assembly can be omitted, i.e. the box can not be used with the base.

[0756] In this embodiment, the base 3B0 can be installed on a vehicle seat through the support leg 3B2 and the plurality of fixing devices 3B3 (for example, International Standards Organization FIX), so that the carrier 3100 can be installed on the vehicle seat (not shown in the figure) through the base 3B0. In another embodiment, the base can also be installed on the vehicle seat through the vehicle safety belt.

[0757] Specifically, as FIG. 32CAs shown, the third bracket 3123 comprises a clamping member 31231, two first structural reinforcing members 31232, 31233 and a second structural reinforcing member 31234. The clamping member 31231 can be a ring-shaped structural member. The two first structural reinforcing members 31232, 31233 are arranged separately from each other along the longitudinal axis direction D31 of the box body 3110. Each of the two first structural reinforcing members 31232, 31233 extends substantially along the transverse axis direction D32 of the box body 3110 and is connected to the clamping member 31231. The two first structural reinforcing members 31232, 31233 are arranged respectively on two sides of the clamping member 31231 to define two clamping regions that limit the movement range of the base 3B0 (when the clamping member 31231 is clamped with the clamping structure 3B1) along the longitudinal axis direction D31. Please refer to FIG. 32E , the second bracket 3122 can be a U-shaped structural member. The second bracket 3122 comprises two vertical portions 31221 and a transverse portion 31222. The two vertical portions 31221 are substantially perpendicular to the first bracket 3121. The transverse portion 31222 is substantially perpendicular to the fixing assembly 3124.

[0758] In addition, please refer to ​ and Figure 32F , Figure 32F is a cross-sectional view of the carrier 3100 according to a first embodiment of the third aspect of the present disclosure. As shown in Figure 32F , the central portion of the second structural reinforcing member 31234 is towards the bottom 3111 of the box body 3110. The height of the central portion is higher than the height of the two side ends, presenting a curved surface shape. In another embodiment, the central portion can also selectively abut against the bottom 3111 (especially the bottom surface) of the box body 3110. As shown in Figure 32EAs shown, the second structural reinforcement 31234 is positioned between the two first structural reinforcements 31232, 31233, the distance between the second structural reinforcement 31234 and the first structural reinforcement 31232 is substantially equal to the distance between the second structural reinforcement 31234 and the first structural reinforcement 31233, and the cross-sectional area of the second structural reinforcement 31234 can be equal to or greater than the cross-sectional area of the two first structural reinforcements 31232, 31233. With the above structural configuration, when the carrier 3100 carries a baby or places other objects, the middle portion of the bottom 3111 of the box body 3110 can have a stress support portion supported by the second structural reinforcement 31234. Furthermore, when the third support 3123 is subjected to external force, it can stably resist a large impact force, thereby making the support device 3120 have high impact resistance and not easily deformed under stress, but the structure of the support device of the present disclosure is not limited to this embodiment and can be determined according to actual design requirements. For example, in another embodiment, if the carrier 3100 is not a long box body structure but a box body structure with four sides substantially equal in length, the second structural reinforcement can be omitted or, if the carrier 3100 has a long box body structure along the longitudinal axis direction D31, a plurality of second structural reinforcements can be further provided to make the box body 3110 have high impact resistance. Alternatively, in another embodiment, the third support can only include one first structural reinforcement positioned on one side of the clamping member. In another embodiment, the carrier 3100 further includes at least one second support along the transverse axis direction D32, but in this embodiment, the at least one second support has a vertically long portion, the at least one second support extends from one side of the peripheral wall 3112 to the other side of the peripheral wall 3112 along the longitudinal axis direction D31 through the bottom 3111, thereby further strengthening the support force on the box body 3110 and improving the impact resistance of the box body 3110. In another embodiment, the carrier 3100 can not include the first structural reinforcements 31232, 31233 and the second structural reinforcement 31234, but a plurality of second supports 3122 are further provided and directly connected to the third support 3123, and the plurality of second supports 3122 can be positioned corresponding to different cross-sectional areas of the box body 3110 along the longitudinal axis direction D31 to improve the impact resistance of the box body 3110.

[0759] In addition, as shown in an embodiment, the first support 3121 can also be a ring-shaped structural member, the first support 3121 surrounds to define a first plane, the clamping member 31231 surrounds to define a second plane, the area of the second plane can be not greater than the area of the first plane, and the area of the second plane is substantially close to the area of the bottom 3111 of the box body 3110. In addition, the first plane and the second plane correspond to the same center axis L (i.e., the center axis L passes through the centers of the first plane and the second plane), and the second structural reinforcement 31234 can be positioned substantially through or close to the center axis. Figure 32C In addition, as shown in an embodiment, the first support 3121 can also be a ring-shaped structural member, the first support 3121 surrounds to define a first plane, the clamping member 31231 surrounds to define a second plane, the area of the second plane can be not greater than the area of the first plane, and the area of the second plane is substantially close to the area of the bottom 3111 of the box body 3110. In addition, the first plane and the second plane correspond to the same center axis L (i.e., the center axis L passes through the centers of the first plane and the second plane), and the second structural reinforcement 31234 can be positioned substantially through or close to the center axis.

[0760] In addition, as shown in Figure 32B , the box 3110 further comprises a receiving structure 3114, which can be a recessed structure, comprising an annular groove 31141 and a U-shaped groove 31142 for partially receiving the first support 3121 and the second support 3122, respectively, so that the box 3110 and the support device 3120 are firmly combined. In another embodiment, the first support and the second support can be completely accommodated in the receiving structure and substantially flush with the surface of the box. Understandably, in another embodiment, the receiving structure can be omitted. Alternatively, in another embodiment, the receiving structure can only comprise an annular groove for partially receiving the first support or a U-shaped groove for partially receiving the second support.

[0761] Further, as shown in Figures 32D to 32F , the box 3110 (e.g. foamed material) can have a first portion and a second portion. The first portion is disposed above the support device 3120 (e.g. above the first support 3121), and the second portion is connected below the first portion. The thickness T1 of the side wall of the first portion near the second portion is greater than the thickness T2 of the side wall of the second portion, and the thickness of the side wall of the first portion can gradually decrease upwards and outwards, forming a curved and smooth upper edge upwards and outwards, so as to increase the comfort when touched and reduce the discomfort when collision occurs. In an example, the first portion and the second portion can be integrally formed, or can be separately manufactured and then combined with each other. In combination Figure 32B and Figure 32F , the surface of the box 3110 and the support device 3120 is substantially flush, and the outer surface of the first portion and the first support 3121 of the support device 3120 is also substantially flush. Of course, in other embodiments, if the overall flatness of the surface of the vehicle is not considered, the support device 3120 can be slightly recessed in the outer surface of the box 3110, or the thickness T1 of the side wall of the first portion near the second portion can be equal to the thickness T2 of the side wall of the second portion, and the support device 3120 at least partially protrudes from the outer surface of the box 3110.

[0762] By arranging the support device (and the device arranged on the support device, such as the ceiling locking portion 4124, 4224, 4324 shown in Figure 40 , Figure 55 , Figure 62A and Figure 62D , and / or the pivot portion of the handle 4160, 4360 shown in Figure 55 and Figure 62A on the outer surface of the box and below the first portion of the box, and arranging, for example, a ceiling frame (see Figure 59A and Figure 62A for supporting the ceiling, the support device can be arranged on the outer surface of the box and below the first portion of the box, and the ceiling frame can be arranged on the support device.) The outer surface of the first part of the box and below the upper edge of the first part can protect the animals in the carrier from directly hitting the hard pipe (such as the U-shaped pipe of the support device, the ceiling locking part, the ceiling frame, or the handle, etc.), thereby further improving the safety.

[0763] Furthermore, as shown in Figure 32C , the fixing assembly 3124 comprises four first connecting supports 31241, each of which connects the corresponding second support 3122 and the corresponding third support 3123, specifically, each of the first connecting supports 31241 connects the corresponding second support 3122 and the corresponding first structural reinforcement 31232, 31233. In an embodiment, the fixing assembly 3124 further comprises a guide assembly comprising four guide members 31242A, 31242B, 31242C, 31242D, the guide member 31242A and the guide member 31242B are connected to the first structural reinforcement 31232 substantially perpendicularly, the guide member 31242C and the guide member 31242D are connected to the first structural reinforcement 31233 substantially perpendicularly, the four guide members 31242A, 31242B, 31242C, 31242D can be arranged in the second plane surrounded by the clamping member 31231, and are respectively located at the corresponding four first connecting supports 31241, the user can guide the third support 3123 to cooperate with the clamping structure 3B1 through the two guide members 31242A, 31242B located at one side of the clamping area of the clamping member 31231 or the other two guide members 31242C, 31242D located at the other side of the clamping area of the clamping member 31231, so that the base 3B0 can be positioned at different positions relative to the carrier 3100, for example, the base 3B0 can be positioned at the opposite sides of the longitudinal axis direction D31 of the bottom 3111 of the carrier 3100.

[0764] However, the number and arrangement position of the guide members of the present disclosure are not limited to this embodiment. For example, in another embodiment, the fixing assembly can comprise one guide member arranged in the middle. Understandably, in another embodiment, the guide member can be omitted.

[0765] In addition, in this embodiment, the guide member 31242 can be a sheet-shaped structural member made of plastic, metal or other materials with certain rigidity, but the present disclosure is not limited to this embodiment.

[0766] Please refer to Figure 32C , Figure 32G , Figure 32H and Figure 32I , Figure 32G is the top view of the carrier 3100 of the first embodiment of the third aspect of the present disclosure, Figure 32H is a partial structural cross-sectional schematic view of the carrier 3100 of the first embodiment of the third aspect of the present disclosure, Figure 32I This is a cross-sectional view of another part of the structure of the vehicle 3100 according to the first embodiment of the third aspect of this disclosure. Figure 32C , Figure 32G , Figure 32H and Figure 32I As shown, the fixing assembly 3124 also includes multiple bracket connectors 31243 (illustrated in...). Figure 32G ), multiple locking combinations 31244 (illustrated in Figure 32H and Figure 32I ) and multiple second connecting brackets 31245 (illustrated in) that connect to the third bracket 3123. Figure 32C In this embodiment, as Figure 32C As shown, multiple second connecting brackets 31245 can be installed on opposite sides of the engaging member 31231 along the longitudinal axis D31, thus making the connection between the housing 3110 and the bracket device 3120 more stable. Since there is no corresponding second bracket 3122 above the second connecting bracket 31245, the length of the second connecting bracket 31245 must be greater than that of the first connecting bracket 31241. Furthermore, the two second connecting brackets 31245 on one side of the engaging member 31231 can be spaced apart from each other. This not only allows the engaging member 31231 to be subjected to more even force on that side, but also allows another element (such as an adjuster 3140) to be placed between the two second connecting brackets 31245, thereby making the structure more compact.

[0767] Furthermore, such as Figure 32C and Figure 32I As shown, the bottom 3111 of the housing 3110 includes a plurality of through slots 31111, which are respectively located at the corresponding first connecting bracket 31241 or second connecting bracket 31245. The plurality of second connecting brackets 31245 are at least partially located in the corresponding through slots 31111. Each locking assembly 31244 may include a locking member 312441 provided in the corresponding bracket connector 31243 and a locking member 312442 for locking with the locking member 312441, so that the housing 3110 and the bracket device 3120 are securely connected.

[0768] like Figure 32H As shown, the bracket connector 31243 located at the corresponding first connecting bracket 31241 can be at least partially located in the through slot 31111 and abut against the transverse portion 31222 of the second bracket 3122. The locking fastener 312442 located at the corresponding first connecting bracket 31241 can pass through the corresponding guide (e.g., guide 31242C), the first structural reinforcement 31233 of the third bracket 3123, the corresponding first connecting bracket 31241, the transverse portion 31222 of the corresponding second bracket 3122, and the corresponding bracket connector 31243 to lock with the corresponding locking member 312442. Figure 32I As shown, the bracket connector 31243 at the corresponding second connecting bracket 31245 can be at least partially positioned in and abut against the corresponding second connecting bracket 31245, and the locking member 312442 at the corresponding second connecting bracket 31245 can be locked with the corresponding locking member 312442 through the engaging member 31231 of the third bracket 3123, the corresponding second connecting bracket 31245 and the corresponding bracket connector 31243.

[0769] However, the number and arrangement of the bracket connectors, the locking assembly, the second connecting bracket and the through slot of the present disclosure are not limited to this embodiment. For example, in another embodiment, the fixing assembly can include one bracket connector arranged centrally, one locking assembly arranged centrally and one second connecting bracket arranged centrally, and the bottom of the box includes one through slot arranged centrally and located at the corresponding second connecting bracket. Alternatively, in another embodiment, the fixing assembly can include one first connecting bracket arranged centrally, one bracket connector arranged centrally and one locking assembly arranged centrally, without including a second connecting bracket, and the bottom of the box includes one through slot arranged centrally and located at the corresponding first connecting bracket.

[0770] It can be understood that in another embodiment, the locking assembly can be omitted, and the bracket connector can be connected to the second bracket or the second connecting bracket through the cooperation of the engaging protrusion and the engaging notch.

[0771] In addition, in order to increase the comfort and safety of the ride, as shown in Figure 32H and Figure 32I As shown, each bracket connector 31243 includes a recess 312431, and the locking member 312441 is accommodated in the recess 312431 without protruding from the bracket connector 31243. In addition, the bottom 3111 of the box 3110 includes seven recesses 31112, and each bracket connector 31243 is partially accommodated in the corresponding recess 31112 without protruding from the bottom 3111 of the box 3110.

[0772] However, the number and arrangement of the recesses of the present disclosure are not limited to this embodiment. For example, in another embodiment, the bottom of the box includes one recess arranged centrally. It can be understood that in another embodiment, the recess and the recessed portion can be omitted.

[0773] Please refer to Figure 32J and Figure 32K , Figure 32J and Figure 32K The restraint webbing configuration schematic diagram of the vehicle 3100 of the first embodiment of the third aspect of the present disclosure is shown from different angles. As shown in Figure 32J and Figure 32KAs shown, the vehicle 3100 also includes restraint webbing 3130 and adjuster 3140. The restraint webbing 3130 includes three mutually cooperating limiting sections 3131 and adjusting sections 3132, thereby confining the child within the accommodating space 3113. Figure 32B , Figure 32C As shown, the bottom 3111 of the housing 3110 also includes three bottom openings 31113 (illustrated in...).

[0783] ​Compared with the prior art, in the present disclosure, the first support is combined with the box body and arranged around the peripheral wall of the box body, and the second support is combined with the box body and extends from one side of the peripheral wall of the box body to the other side of the peripheral wall of the box body through the bottom of the box body, which makes the carrier of the present disclosure not only light in weight and high in structural strength, but also can take into account the carrying convenience and the riding safety.

[0784] It should be noted that the box body of each of the above-mentioned embodiments according to the third aspect of the present disclosure can also be mounted on the wheeled moving device as described in the first aspect and the second aspect of the present disclosure, for example, through the third support of the support device of each of the first aspect and the second aspect, and the specific mounting manner can refer to the foregoing first aspect, which will not be described here.

[0785] In addition to the carriers 3100 to 3700 described in the above-mentioned third aspect of the present disclosure, the fourth aspect of the present disclosure also provides other embodiments of the carrier, for example, a detachable roof assembly and a carrier comprising the same. For the convenience of description, the carrier of the fourth aspect of the present disclosure is represented by “4100” to “4800” respectively.

[0786] Reference is made to Figures 39 to 40 which respectively show the schematic views of the carrier 4100 in different states according to an embodiment of the fourth aspect of the present disclosure, wherein, Figure 39 shows a front view of the carrier 4100, Figure 40 shows Figure 39 shows the structural schematic view of the carrier 4100 after removing the roof and the seat cloth.

[0787] Reference is made to Figure 39 and Figure 40 The carrier 4100 can comprise a box body 4110, a support device 4120 and a roof assembly 4130, wherein the roof assembly comprises a roof frame 4131, a roof locking device 4132 and a roof 4133, which will be described in detail below. It should be noted that the box body 4110 shown in Figure 39 is at least partially sleeved with a seat cloth 4150, and the seat cloth 4150 at least partially covers the box body 4110, the support device 4120 and the roof assembly 4130. For the convenience of description, Figure 40 is the perspective structural schematic view of the carrier 4100 after removing Figure 39 the roof 4133 and the seat cloth 4150 shown.

[0788] As shown in Figure 40 , the box body 4110 (which can also be referred to as “carrying part”) comprises a bottom 4111 and a peripheral wall 4112 connected around the bottom 4111, and the bottom 4111 and the peripheral wall 4112 form a containing space 4113 (i.e., a carrying space). The containing space 4113 has an open top, which is used for children or pets to ride in it.

[0789] In an example, the support device 4120 is disposed at least partially around the box 4110, for example, is sleeved outside the box 4110 from below the box 4110, for supporting the box 4110. The support device 4120 includes a first support 4121, a second support 4122, and a third support 4123. The first support 4121 is disposed substantially horizontally, surrounds the peripheral wall 4112 of the box 4110, and is close to the opening of the box 4110. The two ends of the second support 4122 are respectively connected to the first support 4121, and extend from one side of the peripheral wall 4112 of the box 4110 to the other side of the peripheral wall 4112 of the box 4110 via the bottom 4111 of the box 4110 along the transverse axis direction D42 of the box 4110. Further, in an example, two or more second supports 4122 can be provided, which are respectively connected to the first support 4121 and are disposed in parallel along the longitudinal axis direction D41 and are spaced apart from each other. The third support 4123 is disposed substantially horizontally and is connected to the second support 4122, and is located at the bottom side of the bottom 4111 of the box 4110 and is spaced apart from the bottom 4111 of the box 4110 by a certain distance. It can be seen from Figure 39 that when the seat cloth 4150 is sleeved on the carrier 4100, the third support 4123 of the support device 4120 is exposed. By providing the support device 4120, the carrier 4100 can be supported and fixed on, for example, a trolley or a vehicle seat.

[0790] In combination with Figure 39 and Figure 40 , the ceiling 4133 is sleeved on the opening of the box 4110 to cover the accommodation space 4113 of the box 4110. The ceiling frame 4131 is fixed at the periphery of the ceiling 4133, for supporting the ceiling 4133 above the box 4110, and is detachably disposed at the periphery of the opening of the box 4110. In an example, the ceiling frame 4131 is disposed around the opening of the box 4110 (as shown in Figure 40 ) and causes the ceiling 4133 to be expanded, and the expanded ceiling 4133 covers the ceiling frame 4131 so that it is not visible from the outside (as shown in Figure 39(As shown). A canopy locking device 4132 is provided on the canopy frame 4131 to detachably engage with a corresponding canopy locking part 4124 provided on the carrier 4100, so that the canopy assembly 4130 can be locked above the housing 4110. Specifically, when the canopy assembly 4130 is installed around the housing 4110, the canopy locking device 4132 can engage with the corresponding canopy locking part 4124 on the first bracket 4131 of the support assembly 4130, so that the canopy frame 4131 of the canopy assembly 4130 is detachably connected to the support assembly 4120 of the carrier 4100 (i.e., detachably installed above the housing 4110). In one example, two canopy locking devices 4132 (only one is shown in the figure) can be provided, symmetrically arranged on the canopy frames 4131 on both sides of the housing 4110 in the transverse direction D42. In one embodiment, the ceiling locking device 4132 may be centrally disposed on one side of the ceiling frame 4131 along the longitudinal axis direction D41, that is, the center line of the ceiling locking device 4132 coincides with the center line M41 of one side edge of the ceiling frame 4131. It is understood that the ceiling frame and the ceiling locking device may also be collectively referred to as the "ceiling connection assembly".

[0791] refer to Figures 41 to 43 It schematically illustrates the process of removing the roof assembly 4130 from the housing 4110 according to an embodiment of the fourth aspect of this disclosure, wherein, Figures 41 to 43 The ceiling and seating fabric are omitted to make the structure clearer. Specifically, Figure 41 Show Figure 40 Another angle of the vehicle shown, in which the roof assembly 4130 is mounted to the housing 4110; Figure 42 This shows the state in which the canopy assembly 4130 is being removed from the housing 4110; and Figure 43 This shows the status of the roof assembly 4130 having been removed.

[0792] In one example, such as Figure 41 As shown, when the canopy is needed, the canopy locking device 4132 of the canopy assembly 4130 cooperates with the canopy locking part 4124 to connect the canopy frame 4131 to the first bracket 4121. The canopy frame 4131 is arranged approximately parallel above the first bracket 4121. At this time, the canopy frame 4131 is fitted onto the outside of the housing 4110, so that the canopy (not shown) installed on the canopy frame 4131 is in place. Figure 41 As shown in the figure, please refer to the following: Figure 39 It can cover the entire opening of the housing 4110. For example... Figure 42 and Figure 43As shown, when the canopy is not needed to be used, the canopy locking device 4132 can be separated from the canopy locking portion 4124 provided on the first support 4121, so that the canopy assembly 4130 (including the canopy provided thereon) is separated from the case 4110, at this time, the user can store the canopy assembly 4130. The specific cooperation mode of the canopy locking device 4132 and the canopy locking portion 4124 will be described below.

[0793] Reference Figure 44 , which shows a canopy frame 4131 and a canopy locking device 4132 provided thereon according to an embodiment of the fourth aspect of the present disclosure.

[0794] In an example, the canopy locking device 4132 includes a release operating member 41321. The release operating member 41321 is provided on the canopy frame 4131 and can be operated to move from a locking position to a release position to release the canopy assembly 4130 relative to the case 4110. In addition, the canopy locking device 4132 also includes a locking member 41322, wherein the locking member 41322 is mounted on the canopy frame 4131, and the release operating member 41321 is provided on the canopy frame 4131 and operatively acts on the locking member 41322. As shown, Figure 44 As shown, the locking member 41322 can be at least partially provided in the housing of the canopy frame 4131, and the remaining part extends downward out of the housing for cooperation with the canopy locking portion described above. In addition, the release operating member 41321 can be at least partially provided in the housing of the canopy frame 4131, and the remaining part extends downward out of the housing for the user to contact and operate, thereby releasing the locking member 41322.

[0795] The specific structure and operation principle of the canopy locking device 4132 will be further described in the following description of Figures 45 to 48 . It should be noted that, Figure 45 and Figure 46 respectively show the canopy locking device 4132 when the release operating member 41321 is in the locking position and the release position, and Figure 47 and Figure 48 respectively show the locking and release of the release operating member 41321 relative to the canopy locking portion 4124.

[0796] Reference Figure 45 and Figure 46 , Figure 45 show Figure 44 the structure of the canopy locking device 4132 at part A in Figure 44 , wherein part of the housing at part A shown in Figure 46 shows the specific structure of the canopy locking device 4132 in the locking state; and Figure 45The shown top locking device 4132 is in the structure of the released state.

[0797] As shown in Figure 45 and Figure 46 , in an example, the locking member 41322 is pivotally mounted to the top frame 4131, and the locking operation member 41321 is connected to the locking member 41322 and can move between the locking position Figure 45 and the released position Figure 46 . In an embodiment, the locking member 41322 can be pivoted to the top frame 4131 around a pivot point O41, and pivoted to the released operation member 41321 around another pivot point O42 different from the pivot point O41, the released operation member 41321 can move in the vertical direction relative to the top frame 4131 between the locking position and the released position, and drive the locking member 41322 to pivot relative to the top frame 4131 around the pivot point O41.

[0798] Further, two locking members 41322 can be provided, which are arranged in mirror symmetry in the top locking device 4132, and are respectively pivoted to both sides of the same released operation member 41321. For example, the two locking members 41322 are respectively pivoted to the top frame 4131 at two pivot points O41 symmetrical along the center line M41, and are respectively pivoted to the two ends of the released operation member 41321 at the pivot points O42.

[0799] As shown in Figure 45 and Figure 46 , in an example, the top locking device 4132 can further include a resilient reset member 41323. The resilient reset member 41323 is connected between the released operation member 41321 and the top frame 4131, and constantly provides a force to make the released operation member 41321 in or return to the locking position. That is, as shown in Figure 45 , the resilient reset member 41323 constantly applies a vertically downward force to the released operation member 41321, so that the released operation member 41321 always has a tendency to protrude from the housing of the top frame 4131.

[0800] Referring to Figure 47 and Figure 48 , Figure 47 , a schematic view of the top locking device 4132 locked with the top locking portion 4124 is shown, and Figure 48 , a schematic view of the top locking device 4132 released with the top locking portion 4124 is shown.

[0801] In combination with reference to Figure 47 and Figure 48, the locking member 41322 is pivotally mounted to the ceiling frame 4131 and engages or disengages with the ceiling locking portion 4124 through movement relative to the ceiling frame 4131, thereby locking or releasing the ceiling frame 4131 to the case (not shown). Specifically, when the release operating member 41321 is located at the locking position (see Figure 47 ), the locking member 41322 engages with the ceiling locking portion 4124; when the release operating member 41321 is operated to the release position (see Figure 48 ), the locking member 41322 disengages with the ceiling locking portion 4124.

[0802] In an example, as shown in Figure 47 and Figure 48 , the locking member 41322 has a hook extending towards the ceiling locking portion 4124, and the ceiling locking portion 4124 includes a corresponding locking pin 41241. When the release operating member 41321 is at the locking position, the hook engages with the locking pin 41241. When the release operating member 41321 is operated to push the locking member 41322 to pivot at the release position, the hook disengages with the locking pin 41241. More specifically, further in combination with Figure 42 , Figure 47 and Figure 48 , when it is required to detach the ceiling assembly 4130 from above the case 4110, a user can operate (e.g. press) the release operating member 41321, which drives the locking member 41322 pivotally connected thereto to pivot through movement of the release operating member 41321 in the vertical direction, thereby pivoting from the locking position to the release position, so that the hook of the locking member 41322 disengages from the locking pin 41241 of the ceiling locking portion 4124 provided on the first support 4121, thereby achieving release, so that the ceiling assembly 4130 can be removed.

[0803] In addition, as shown in Figure 47 , the ceiling frame 4131 is further provided with a locking guide 41316. The locking guide 41316 is provided on one side of the locking member 41322 and can guide the positioning of the ceiling locking device 4132 relative to the ceiling locking portion 4124 to assist the locking of the locking member 41322 with the ceiling locking portion 4124. For example, when the ceiling assembly 4130 is installed to the first support 4121 provided with the ceiling locking portion 4124 (not shown in Figure 47 , see Figure 42 ), the locking guide 41316 can be arranged to abut against the inner edge of the ceiling locking portion 4124 to guide the ceiling locking device 4132 and cause it to be arranged correspondingly with the ceiling locking portion 4124, thereby causing the hook of the locking member 41322 to engage or release with the corresponding locking pin 41241 of the ceiling locking portion 4124.

[0804] Reference is made to Figure 49 and Figure 50 It illustrates different states of a canopy frame 4131 according to an embodiment of the fourth aspect of this disclosure, wherein Figure 49 The ceiling frame 4131 is shown in the unfolded state. Figure 50 The roof frame 4131 is shown in a folded-down state.

[0805] In one example, the canopy frame 4131 has a three-section folding structure. For example... Figure 49 and Figure 50 As shown, the ceiling frame 4131 may include a first pivot segment 41311, a second pivot segment 41312, and two locking segments 41315. The two ends of the first pivot segment 41311 are pivotally connected to one end of each of the two locking segments 41315 via a first pivot portion 41313, and the two ends of the second pivot segment 41312 are pivotally connected to the other end of each of the two locking segments 41315 via a second pivot portion 41314. Each of the two locking segments 41315 is provided with a ceiling locking device 4132. In one example, the size of the locking segment 41315 with the ceiling locking device 4132 according to this disclosure may be between 160mm and 180mm, optionally 173mm.

[0806] refer to Figures 51A to 51C , Figure 51A Show along Figure 49 The figure shown is a sectional perspective view of the first pivot portion 41313 cut by line KK. Figure 51B The structure of the first pivot 41313 on the locking section 41315 side is shown, and Figure 51C The structure of the first pivot portion 41313 on one side of the first pivot segment 41311 is shown.

[0807] like Figures 51A to 51C As shown, a position adjustment structure, such as a gear tooth, is provided at the first pivot portion 41313, allowing the first pivot segment 41311 to be held at different angles relative to the locking segment 41315. Specifically, the first pivot portion 41313 is formed by the pivoting of the first pivot segment 41311 and the locking segment 41315, as shown in the figure. Figure 51B As shown, the end of the locking segment 41315 is provided with a first stop tooth 41313a, and as shown in the figure. Figure 51C As shown, the end of the first pivot segment 41311 is provided with a second stop tooth 41313b. Similarly, the second pivot portion 41314 can also be provided with the same structure as the first pivot portion 41313, that is, provided with a stop tooth, so that the second pivot segment 41312 can be maintained at different angles relative to the locking segment 41315. This disclosure is not limited to this, and the roof frame 4131 can also be provided with other segment adjustment structures so that the pivot segment of the roof frame 4131 is at different angles relative to the opening of the housing.

[0808] Furthermore, such as Figure 51A As shown, a return spring 41313c is also provided in the first pivot portion 41313, which constantly biases the first pivot portion 41313 in the direction that causes the roof frame 4131 to unfold, in order to provide assistance during the unfolding of the roof frame. Similarly, a return spring can also be provided in the second pivot portion 41314 to help unfold the roof frame.

[0809] refer to Figures 52 to 54B They respectively show the box 4110 with the roof frame 4131 installed in different states, wherein, Figure 52 The roof frame 4131 and Figure 54A The canopy 4133 is in the extended state. Figure 53 The roof frame 4131 and Figure 54B The canopy 4133 is in a folded-down state.

[0810] Reference Figure 52 and Figure 54A When the canopy 4133 is installed above the housing 4110, the canopy locking device 4132 provided in the locking section 41315 can lock with the canopy locking part 4124 provided on the first bracket 4121, so that at least a part of the canopy frame 4131 (i.e., the locking section 41315) is locked to the first bracket 4121 fitted on the outside of the housing 4110. When the canopy frame 4131 is in such a position... Figure 52 The roof 4133 is in the unfolded state, arranged around the opening of the housing 4110, i.e., when the first pivot section 41311, the locking section 41315, and the second pivot section 41312 are approximately on the same horizontal line (as shown). Figure 54A As shown), and covered above the opening of the box 4110, at which time the roof frame 4131 is covered by the roof 4133 and is not visible from the outside.

[0811] Reference Figure 53 and Figure 54B When it is necessary to fold down the ceiling 4133, the first pivot segment 41311 and / or the second pivot segment 41312 of the ceiling frame 4131 can be moved to pivot about the first pivot portion 41313 and / or the second pivot portion 41314 relative to the locking segment 41315, thereby partially or completely folding down the ceiling frame 4131 and the ceiling 4133 fixedly connected thereto. For example Figure 54B The fully folded canopy 4133 is shown. Simultaneously, by means of the stop teeth provided in the first pivot portion 41313 and / or the second pivot portion 41314, the canopy frame and the canopy 4133 can be positioned in at least one folded position, allowing for adjustment of the opening size of the canopy 4133 relative to the housing 4110, facilitating user operations and improving safety and convenience. In one example, such as... Figure 53 and Figure 54B As shown in

[0812] In addition, as shown in Figure 54A and Figure 54B , a connecting structure is provided between the roof 4133 and the box 4110 of the carrier 4100 for keeping the roof 4133 closed relative to the box 4110.

[0813] In an example, the connecting structure comprises a connector and a mating connector. The connector is provided on opposite sides of the box 4110, while the mating connector is provided on corresponding sides of the roof 4133 and engages with the connector, wherein one of the connector and the mating connector is a male connector (e.g. Figure 54B “4114”) and the other is a female connector (e.g. Figure 54A and Figure 54B “41335”), and the roof 4133 is kept closed by the engagement of the male connector 4114 and the female connector 41335. It is noted that Figure 54A and Figure 54B only show one example of the male connector and the female connector (i.e. the male connector 4114 is provided on the box 4110, while the female connector 41335 is provided on the roof 4133), but the positions of the two can be interchanged, that is, the male connector can be provided on the roof, while the female connector is provided on the box. For example, the male connector 4114 and the female connector 41335 are a magnetic buckle assembly that cooperates with each other.

[0814] In addition, as shown in Figure 54A and Figure 54B , flexible handles 4151 (only one side of the flexible handle is shown in the figure) can also be provided on the two sides of the box 4110, and when the user needs to move the carrier 4100, the carrier 4100 can be dragged or lifted by gripping the flexible handles 4151 on the two sides of the box 4110. In an example, the flexible handle 4151 can be sewn on the seat cloth 4150 wrapped outside the box 4110 and located below the male connector 4114. However, the present disclosure is not limited thereto, that is, the flexible handle 4151 can also be fixed or detachably provided on the two sides of the box 4110 by other means.

[0815] Referring to Figure 55 , a carrier 4100 according to an embodiment of the fourth aspect of the present disclosure is shown, wherein the roof is removed. As shown in Figure 55As shown, any side of the carrier 4100 can also be provided with a bag 4152, such as being pasted or sewn on a seat cloth 4150 wrapped outside the box 4110, for placing smaller items such as a shoulder bag. In addition, the bag 4152 can at least partially cover the connector, such as the male connector 4114, provided on the box 4100, so as to avoid affecting the appearance or being damaged due to collision, and the opening edge of the bag 4152 is provided in an elastic and tight structure, facilitating better placement of items.

[0816] In an example, as shown in Figure 55 , the carrier 4100 can also be provided with a handle 4160, for example, two ends of the handle 4160 can be respectively provided on both sides of the carrier 4100 and symmetric to the top locking part 4124, for the user to carry the carrier 4100. The position of the handle 4160 in the upright state is higher than the height of the top (not shown in the top) when it is folded, and the width of the handle 4160 is greater than the width of the top, so as to avoid interference with the folding of the top. In particular, reference can be made to Figure 55 and Figure 55 , Figure 54B (illustrating the folded top 4133) and Figure 53 (illustrating the top frame 4131 supporting the top), the position of the handle 4160 in the upright state is higher than the first pivot segment 41311 and the second pivot segment 41312 in the upright state (i.e., fully folded) and the top 4133 provided thereon, and the width of the handle 4160 in the transverse direction D42 is greater than the width of the first pivot segment 41311 and the second pivot segment 41312 and the top 4133.

[0817] Reference is made to Figure 56 , Figure 57A and Figure 57B , Figure 56 , which shows a perspective view of a carrier 4200 according to another embodiment of the fourth aspect of the present disclosure, wherein the top covering the box 4210 and the seat cloth covering the outside of the box 4210 are removed; Figure 57A , which shows another perspective view of the carrier 4200, wherein the release operation member as shown in Figure 56 is also removed; Figure 57B , which shows a partial enlarged view at H portion in Figure 57A ; and Figure 57C , which shows a partial cross-sectional perspective view of the top locking device taken along line G-G in Figure 57A .

[0818] In the present embodiment, the carrier 4200 differs from the carrier 4100 shown in Figure 39 mainly in that the top locking device 4232 has a different structure.

[0819] Reference is made to Figure 56 、 Figures 57A to 57C The roof assembly 4230 of the vehicle 4200 includes a roof frame 4231, a roof locking device 4232, and a roof (not shown for the purpose of observation, the roof of the present embodiment has the same structure as the roof 4133). The roof frame 4231 surrounds the opening of the box 4210, and the roof locking device 4232 is at least partially disposed on the roof frame 4231 to cooperate with the roof locking portion 4224 disposed correspondingly on the vehicle 4200 to lock the roof assembly 4230 above the box 4210. In an example, the vehicle 4200 has two roof locking devices 4232 (only one is shown in the figure) disposed symmetrically on the roof frame 4231 on both sides of the transverse axis direction D4 of the box 4210, and cooperates detachably with the roof locking portion 4224 disposed on the first bracket 4221.

[0820] In an example, the roof locking device 4232 can include a release operating member 42321 (see Figure 56 ) and a locking member 42322 (see Figure 57B ). The release operating member 42321 can be operated to move from a locked position to a released position to release the roof assembly 4230 relative to the box 4210. The release operating member 42321 is disposed on a bracket device, such as the first bracket 4221, which is sleeved outside the box 4210. As shown in Figure 56 , the release operating member 42321 can be disposed outside the roof locking portion 4224, and the specific arrangement and operating principle will be described below. Figures 57A to 57C The structure for removing the release operating member 42321 is shown in the figure to show the perspective view of the roof locking device 4232 cooperating with the roof locking portion 4224.

[0821] As shown in Figure 57A and Figure 57B , the locking member 42322 can be provided as a first sheet member, such as fixedly connected to the roof frame 4231 by rivets, and extending from the roof frame 4231 to the bracket device (such as the first bracket 4221 shown in the figure) of the vehicle 4200.

[0822] In addition, the roof locking portion 4224 can include a second sheet member 42241. In combination with reference to Figure 58A and Figure 58B , which respectively show different angles of the second sheet member 42241. In an example, the second sheet member 42241 can be provided in the shape of an inverted trapezoid.

[0823] In combination with Figures 57A to 58BIt can be seen that the locking member 42322 (i.e., the first piece) and the second piece 42241 of the canopy locking part 4224 can be provided with a mutually engaging locking structure. In one example, one of the first piece 42322 and the second piece 42241 has an engaging hole, while the other of the first piece 42322 and the second piece 42241 has an engaging protrusion that engages with the engaging hole. For example, as Figure 57B and Figure 57C and Figure 58A As shown, the first sheet-like member 42322 is provided with an engaging hole 42322a, and the second sheet-like member 42241 of the roof locking part 4224 is correspondingly provided with an engaging protrusion 42241a. When in the locked state, the engaging hole 42322a and the engaging protrusion 42241a engage with each other. However, this disclosure is not limited to this, and the locking member 42322 and the roof locking part 4224 may also have other corresponding structures.

[0824] See again Figures 59A to 59C The figures show cross-sectional perspective views of the roof locking device in different states.

[0825] Further reference Figure 59A and Figure 59B Taking the locking member 42322 as the first piece and the roof locking part 4224 including the second piece 42241 as an example, the unlocking operation member 42321 is disposed on the roof locking part 4224 and can be in the locked position relative to the roof locking part 4224 in the front-back direction (see...). Figure 59A ) and release position (see Figure 59B The second piece 42241 of the ceiling locking part 4224 is connected to the release operation member 42321 so as to be able to move with the operation of the release operation member 42321, wherein an insertion space for accommodating the first piece (i.e., the locking member 42322) is formed between the second piece 42241 and the release operation member 42321.

[0826] In one example, the canopy locking device 4232 further includes a resilient reset member 42323, connected to one of the release operation member 42321 and the second piece 42241 and the support device of the vehicle (e.g., Figure 59A Between the first bracket 4221 shown, a force is constantly provided to put the release operation member 42321 into or return it to the locked position.

[0827] The following will combine Figures 59A to 59C The structure and operating principle of the ceiling locking device 4232 will be further explained.

[0828] When the ceiling is installed, such as Figure 59AAs shown, the elastic return member 42323 pushes the second sheet member 42241 and the release operation member 42321, so that the release operation member 42321 is kept in the locked position, and the engaging hole 42322a of the first sheet member 42322 is engaged with the engaging protrusion 42241a of the second sheet member 42241. When it is needed to release the lock, as shown, the release operation member 42321 can be pressed to the release position, so that the release operation member 42321 pushes the second sheet member 42241 away from the first sheet member 42322 against the force of the elastic return member 42323, and the engaging hole 42322a is disengaged from the engaging protrusion 42241a. At this time, as shown, the roof frame 4231 can be moved upward, and the first sheet member 42322 is removed from the insertion space between the second sheet member 42241 and the release operation member 42321, so that the roof is detached from the box. Figure 59B Figure 59C

[0829] Referring to Figure 60 and Figure 61 , which respectively show the unfolded state and the folded state of the roof frame 4231 according to another embodiment of the present disclosure.

[0830] Similar to the structure of the roof frame 4131 in the foregoing embodiments, the roof frame 4231 of the present embodiment comprises a first pivot segment 42311, a second pivot segment 42312, and two locking segments 42315, the two ends of the first pivot segment 42311 are respectively pivotably connected to one end of the two locking segments 42315 through first pivot joints 42313, the two ends of the second pivot segment 42312 are respectively pivotably connected to the other end of the two locking segments 42315 through second pivot joints 42314, and the two locking segments 42315 are respectively provided with a roof locking device 4232. The difference is that the locking segment 42315 provided with the roof locking device 4232 of the present embodiment can have a smaller size, for example, can be between 110 mm and 135 mm, and optionally 125 mm, so as to further improve the adaptability of the roof assembly to different sizes of carriers.

[0831] For example, referring to Figures 62A to 63D , Figures 62A to 62F and Figure 63A and FIG. 63D , which respectively show the use of the roof locking device in cases of boxes with different sizes.

[0832] FIGS. 62A-62C As shown, the carrier 4300 comprises a box 4310, a support device 4320, and a roof assembly 4330, the support device 4320 is sleeved outside the box 4310 and comprises a first support 4321, a second support 4322, and a third support 4323. Specifically, FIG. 62A ​​Fig. 43B shows the carrier 4300 after the ceiling assembly 4330 is removed, FIG. 62B Fig. 43C shows the carrier 4300 after the ceiling assembly 4330 is removed, FIG. 62C Fig. 43D shows the carrier 4300 after the ceiling assembly 4330 is removed. As FIGS. 62A-62C shown, the carrier 4300 can have two ceiling locking portions 4324 corresponding to the ceiling locking devices 4332 provided on the ceiling frame 4331 respectively. The two ceiling locking portions 4324 can be symmetrically provided on both sides of the first support 4321 of the support device 4320 relative to the case 4310, and can be located in the middle of one side of the case 4310, i.e. in the middle of one side edge of the first support 4321. As FIG. 62C shown, a structural reinforcement 43233 can be provided under the carrier 4300 in the longer dimension, e.g. in the middle of the third support 4323 in the longitudinal direction D41, to further enhance the structural strength of the support device 4320. It should be noted that although the ceiling locking device shown in this embodiment is similar to that shown in FIG. 56 , it should be clear to those skilled in the art that this embodiment is also applicable to the ceiling locking device shown in FIG. 40 .

[0833] In addition, in order to facilitate carrying, the carrier 4300 can also be provided with a handle 4360. In a specific example, as FIGS. 62A-62C shown, the two ends of the handle 4360 can be symmetrically provided on the support device 4320. For example, the two ends of the handle 4360 can be provided on the first supports 4321 located on both sides of the case 4310 respectively, and avoid the ceiling locking portions 4324, more specifically, can be provided adjacent to the ceiling locking portions 4324, so as not to interfere with the ceiling locking portions 4324 when lifting the carrier 4300 by the handle 4360, and at the same time ensure that the carrier 4300 will not be tilted too much. Similar to the handle 4160 in the foregoing embodiment, the position of the handle 4360 when standing upright is higher than the height of the ceiling (not shown) when folded, and the width is greater than the width of the ceiling. FIGS. 62A-62C

[0834] In another specific example, as FIGS. 62D-62F ​As shown, the carrier 4300a can have a similar structure as the carrier 4300 in the foregoing examples. Specifically, the carrier 4300a includes a box 4310a, a bracket device 4320a, and a roof assembly 4330a, the bracket device 4320a being sleeved outside the box 4310a. Two roof locking portions 4324a of the carrier 4300a can be symmetrically arranged on both sides of a first bracket 4321a of the bracket device 4320a relative to the box 4310a, and can be respectively located in the middle of one side of the box 4310a. The two roof locking portions 4324a respectively correspond to roof locking devices 4332a arranged on a roof frame 4331a. The difference from the carrier 4300 is that a handle 4360a can be arranged on the roof assembly 4330a of the carrier 4300a, for example, at the roof locking devices 4332a (i.e., in the middle of the roof assembly 4330a, and the structure of the handle 4360a does not interfere with the structure of the roof locking devices 4332a), so that the handle 4360a can be removed from the box 4310a together with the roof assembly 4330a. Specifically, two ends of the handle 4360a can be respectively arranged at positions corresponding to the roof locking portions 4324a on the roof frame 4331a. As shown in FIG. 43B, when the roof frame 4331a is folded relative to each other, the handle 4360a is in an upright state and located between the first and second pivot segments 43311a and 43312a after folding. Similar to the handle 4160, 4360 in the foregoing examples, the position of the handle 4360a in the upright state is higher than the height of the roof when the roof is folded (see FIG. 43C, which shows the roof frame 4331a after the roof is removed), and the width is greater than the width of the roof. FIG. 62F FIG. 62F

[0835] FIGS. 63A-63D As shown, the carrier 4400 has a shorter dimension, wherein the carrier 4400 includes a box 4410, a bracket device 4420, and a roof assembly 4430, the bracket device 4420 being sleeved outside the box 4410 and including a first bracket 4421, a second bracket 4422, and a third bracket 4423. Specifically, FIG. 63A the roof of the roof assembly 4430 is removed in FIG. 44B, FIG. 63B the roof assembly 4430 is removed in FIG. 44C, FIG. 63C and FIG. 63D As shown, the carrier 4400 has a shorter dimension, wherein the carrier 4400 includes a box 4410, a bracket device 4420, and a roof assembly 4430, the bracket device 4420 being sleeved outside the box 4410 and including a first bracket 4421, a second bracket 4422, and a third bracket 4423. Specifically, FIG. 63A and FIG. 63B ​​As shown, the carrier 4400 can have two roof locking portions 4424, each corresponding to a roof locking device 4432 arranged on the roof frame 4431. The specific arrangement of the roof locking portions 4424 is similar to that of the roof locking portions 4324 of the carrier 4300 with a longer dimension, which will not be repeated here. The difference is that the carrier 4400 with a shorter dimension can not be provided with a handle and a structural reinforcement connected to the third support 4423, but the present disclosure is not limited thereto. In the case of no conflict in structure, the carrier 4400 with a shorter dimension can also be provided with a handle and a structural reinforcement connected to the third support 4423, which will not be repeated here. FIG. 62D and FIG. 62E a similar handle, which will not be repeated here.

[0836] In addition, in combination with FIG. 63A and FIG. 63C it can be seen that when the roof 4433 is mounted on the roof frame 4431, the roof 4433 shields the roof frame 4431 and the roof locking device 4432 to increase the aesthetics of the carrier 4400. In particular, further referring to FIG. 63A and FIG. 63D , the lower edge of the roof 4433 can be sleeved on the first pivot segment 44311 and the second pivot segment 44312 of the roof frame 4431, respectively, and detachably connected to the locking segment 44315. For example, as shown in FIG. 63D , the locking segment 44315 can be provided with a first fastener 4436, and a second fastener 4437 arranged on the roof 4433 can be detachably connected to each other to increase the connection stability between the roof 4433 and the roof frame 4431, thereby reducing the probability of separation of the roof 4433 and the roof frame 4431 as much as possible. Alternatively, the first fastener 4436 and the second fastener 4437 can be snap-type connecting devices matched with each other, that is, the first fastener 4436 can be a female buckle of a snap-type connecting device, and the second fastener 4437 can be a male buckle matched with the female buckle, but the present disclosure is not limited thereto, and the positions and / or structures of the first fastener 4436 and the second fastener 4437 can be interchanged. In addition, the first fastener 4436 and the second fastener 4437 can also adopt other ways, such as magic tape, slide buckle structure, hook and loop structure, button structure, etc.

[0837] Referring to FIGS. 64A-64D , a carrier 4500 provided with a shoulder strap 4540 according to still another embodiment of the fourth aspect of the present disclosure is shown.

[0838] As shown in FIGS. 64A-64D , the shoulder strap 4540 includes a strap body 4541 and shoulder strap connecting portions 4542 arranged at both ends of the strap body 4541, respectively, and the shoulder strap connecting portions 4542 are connected to each other with connecting members 4514 arranged on opposite sides of the box body 4510. In an example, as shown in FIG. 64C andFIG. 64D As shown, the shoulder strap connecting portion 4542 of the shoulder strap 4540 and the connector 4514 provided on the case 4510 can be mutually cooperating magnetic buckle components, but this disclosure is not limited to this. For example, the shoulder strap connecting portion 4542 can be a hook and used in conjunction with a corresponding D-shaped buckle on the case 4510. That is to say, the shoulder strap connecting portion 4542 and the connector 4514 can also be any components that can be connected, such as a buckle structure, a concave-convex structure, a hook and loop structure, etc. In addition, in another embodiment, at least one connector 4514 on the case 4510 can also be provided on the opposite long side of the case 4510 (diagonally), and this disclosure does not limit the placement of at least one connector 4514.

[0874] As FIG. 72As shown, the carrier 5100 (e.g., a pet carrier) of the present disclosure comprises a box 5110 and a support assembly 5120. The box 5110 (i.e., a carrying portion) comprises a body 5111 and a bottom support 5112, the body 5111 being detachably covered on the bottom support 5112 (i.e., as a peripheral wall of the box 5110) to form, with the bottom support 5112, a receiving space (i.e., a carrying space) for a pet to ride. The bottom support 5112 constitutes a bottom of the box 5110, wherein an upper surface of the bottom support 5112 (i.e., an upper surface of the bottom of the box 5110) is located in the receiving space, while a lower surface of the bottom support 5112 (i.e., a lower surface of the bottom) constitutes a bottom surface of the box 5110. The body 5111 constitutes four side surfaces and a top surface of the box 5110. The body 5111 is detachably connected to the bottom support 5112 by at least one connecting assembly. Specifically, in an example, the at least one connecting assembly comprises a first connecting piece 51116 and a second connecting piece 51117 detachably connected to each other, wherein the first connecting piece 51116 is arranged on the body 5111, and the second connecting piece 51117 is arranged on the bottom support 5112. In a specific example, the first connecting piece 51116 and the second connecting piece 51117 are interfitting zippers, but the present disclosure is not limited thereto, for example, they can also be interfitting snap structures, slide buckle structures, hook and loop fasteners, hooks and loops, etc., and optionally, a soft connection is adopted. Alternatively, in another example, the body 5111 and the bottom support 5112 can be fixedly connected (e.g., sewn together) or integrally formed.

[0875] In combination FIG. 72 and FIG. 73 , the support assembly 5120 is used to fix the carrier 5100 to a moving device, such as a vehicle or a trolley, etc. The box 5110 is arranged on the support assembly 5120 via the bottom support 5112. As shown, FIG. 73 , the support assembly 5120 comprises a clamping piece 5121 cooperating with a clamping structure correspondingly arranged on the moving device, and the specific clamping manner will be specifically described below in the description of FIGS. 81-86 . In an example, the clamping piece 5121 can be in the form of a ring structure arranged spaced apart from the bottom of the bottom support 5112. Wherein the center of the clamping piece 5121 substantially corresponds to the center of the box 5110 in the vertical direction. The support assembly 5120 (which can also be referred to as a "support device") can have a structure similar to the third support 3123 (see FIG. 32B and FIG. 32C ) according to the third aspect of the present disclosure, for example, the clamping piece 5121 of the present embodiment can correspond to the clamping piece 31231 as shown in FIG. 32B and FIG. 32C , and the structure reinforcing piece 5124 can correspond to the structure reinforcing piece 31232 as shown inFIG. 32C The second structural reinforcement 31234, and the engaging member 5121 and the structural reinforcement 5124 can be collectively referred to as a "third support" of the present embodiment.

[0876] In addition, the support assembly 5120 can further include four first connecting supports 5122 disposed on the engaging member 5121 to connect with the bottom of the box 5110 and spaced apart from each other, for example, disposed near the four corners of the bottom of the box 5110 respectively, thereby providing balanced and stable support for the box 5110. Further, the four first connecting supports 5122 can be symmetrically disposed on opposite sides of the engaging member 5121 along the transverse axis direction with respect to the longitudinal axis direction D51 and the transverse axis direction D52 of the carrier 5100. For example, as shown in FIG. 2 the four first connecting supports 5122 are symmetrically disposed on the two long sides of the annular structural member of the engaging member 5121 respectively. It should be understood that the engaging member of the present disclosure is not limited to the above shape, and the first connecting supports 5122 are not limited to the above number. Alternatively, in another example, only two first connecting supports 5122 can be provided, and the two first connecting supports 5122 are disposed diagonally. In other examples, the number of first connecting supports 5122 can also be three, five, etc.

[0877] Further, the support assembly 5120 can further include a plurality of second connecting supports 5123 respectively disposed on opposite sides of the engaging member 5121 along the longitudinal axis direction D51 and connected to the bottom of the box 5110, thereby further stabilizing the combination of the box 5110 and the support assembly 5120. It should be noted that although only two second connecting supports 5123 are shown in FIG. 2 the present disclosure is not limited thereto, and four, six, etc. can also be provided. In addition, it should be noted that in other examples, the first connecting supports 5122 and the second connecting supports 5123 can be provided alternatively, as long as the combination of the box 5110 and the support assembly 5120 can be stabilized, and the present disclosure does not limit this.

[0878] In addition, the support assembly 5120 can further include a structural reinforcement 5124 located at approximately the middle position of the engaging member 5121 along the longitudinal axis direction D51. The central portion of the structural reinforcement 5124 is curved towards the bottom of the box 5110, i.e., the height of the central portion is higher than the height of the two side ends, thereby making the support assembly 5120 have higher impact resistance and not easy to be deformed under force.

[0879] The first connecting bracket 5122 and the second connecting bracket 5123 can also be collectively referred to as a "fixing assembly", which is arranged between the box body and the third bracket (including the clamping piece 1521) to space the third bracket from the bottom of the box body. It should be noted that the structure of the bracket assembly of the present disclosure is not limited to this embodiment.

[0881] As FIG. 74 shown, the body 5111 includes a first support and a second support, for example, in the present embodiment, the first support is a side support 51111, and the second support is an upper support 51112. The side support 51111 and the upper support 51112 are detachably connected to each other, for example, by a zipper connection or by other connection means such as a magic tape. However, it can be understood that the first support and the second support can also be arranged in other structures according to the structure of the body 5111, for example, the first support and the second support can also be arranged as each half of the body 5111, i.e. having a mirror-symmetrical shape.

[0882] Further, in an example, in combination FIG. 74 and FIG. 75 , the side support 51111 can include a first sub-support 51111a and a second sub-support 51111b, which are detachably connected on both sides of the upper support 51112 (i.e. the upper support 51112 is between the first sub-support 51111a and the second sub-support 51111b) to form the body 5111. Among them, the first sub-support 51111a and the second sub-support 51111b form two side surfaces of the body 5111. More specifically, the first sub-support 51111a and the second sub-support 51111b are independent of each other and each have a bottom edge 51111m extending approximately horizontally and a top edge 51111n in an arch shape, the bottom edges 51111m of the first sub-support 51111a and the second sub-support 51111b are detachably connected to the corresponding edges of the bottom support 5112, and the top edges 51111n thereof are detachably connected to both sides of the arch-shaped upper support 51112.

[0883] In an example, as FIG. 75As shown, the first sub-support 51111a and the second sub-support 51111b can be connected to each other by a connecting structure to be connected together to the bottom support 5112 (see FIG. 2 ), for example, a first connecting member 51116. Specifically, the first connecting member 51116 is connected to the bottom edges 51111m of the first sub-support 51111a and the second sub-support 51111b. Optionally, the first connecting member 51116 is of a soft material (i.e., foldable, deformable, etc.), for example, a zipper structure, cloth, etc., such that after the side support 51111 is detached from the bottom support 5112 (see FIG. 2 ) and separated from the upper support 51112, the first sub-support 51111a and the second sub-support 51111b can be folded relative to each other.

[0884] Optionally, the side support 51111 can be made of a material having a certain pressure bearing capacity to prevent deformation during transportation, for example, paperboard, plastic board, metal plate, etc., but the present disclosure is not limited thereto.

[0885] As shown in FIG. 74 and FIG. 76 , the upper support 51112 is composed of three sheet-shaped members 51112a, 51112b, 51112c connected to each other and in an arched shape. The three sheet-shaped members 51112a, 51112b, 51112c can form the top surface and the other two side surfaces of the body 5111, respectively, for example, the first sheet-shaped member 51112a and the third sheet-shaped member 51112c form the other two side surfaces of the body 5111 (i.e., between the side surfaces formed by the first sub-support 51111a and the second sub-support 51111b), and the second sheet-shaped member 51112b forms the top surface of the body 5111. Optionally, the three sheet-shaped members 51112a, 51112b, 51112c can be made of a material having a certain pressure bearing capacity to prevent deformation during transportation, for example, paperboard, plastic board, metal plate, etc., but the present disclosure is not limited thereto.

[0886] In an example, the first sheet-shaped member 51112a and the second sheet-shaped member 51112b can be connected to each other by a connecting structure (not shown due to occlusion) and can be folded relative to each other, and the second sheet-shaped member 51112b and the third sheet-shaped member 51112c can be connected by another connecting structure (see FIG. 76The first, second and third sheet-shaped pieces 51112a, 51112b, 51112c are connected to each other and can be folded relative to each other, such that the first sheet-shaped piece 51112a and the third sheet-shaped piece 51112c can be folded inward relative to the second sheet-shaped piece 51112b. That is, the two side sheet-shaped pieces can be folded inward, i.e. relative to the middle sheet-shaped piece, so that the disassembled upper support 51112 can be folded to reduce its volume, thereby further reducing the space required for storage and reducing transportation costs. The above connection structure and the other connection structure can be a soft connection structure, such as a sewn cloth, or a rigid connection structure. In a specific example, the upper support 51112 can be formed as a whole (e.g. by sewing, etc.) through the above connection structure, i.e. the three sheet-shaped pieces 51112a, 51112b, 51112c are formed as a whole. In addition, as shown in FIG. 74 The top side (i.e. the second sheet-shaped piece 51112b) of the upper support 51112 can be provided with a handle 51115, for example at the central position of the top side, for lifting and carrying the carrier.

[0887] In an example, as shown in FIG. 76 The two side edges of the upper support 51112 are respectively provided with third connecting pieces 51118a, 51118b, which can be matched with fourth connecting pieces 51119a, 51119b (see FIG. 75 ) respectively provided on the top edges 51111n of the first and second sub-supports 51111a, 51111b. The third connecting pieces 51118a, 51118b and the fourth connecting pieces 51119a, 51119b are detachably connected, so that the upper support 51112 is detachably connected to the first and second sub-supports 51111a, 51111b. The third connecting pieces 51118a, 51118b and the fourth connecting pieces 51119a, 51119b can be soft connecting pieces, such as a zipper structure, but the present disclosure is not limited thereto. In other examples, the third connecting pieces 51118a, 51118b and the fourth connecting pieces 51119a, 51119b can also be a snap structure, a slide buckle structure, a hook and loop cooperation, etc. Specifically, as shown in FIG. 75 The fourth connecting piece 51119a (e.g. a zipper structure) provided on the first sub-support 51111a extends along the entire top edge 51111n of the first sub-support 51111a. Additionally or alternatively, the fourth connecting piece 51119b (e.g. a zipper structure) provided on the second sub-support 51111b extends along the entire top edge of the second sub-support 51111b. Correspondingly, as shown in FIG. 76As shown, the third connecting members 51118a, 51118b (e.g., a zipper structure) on both sides of the upper support member 51112 can respectively extend along the entire side edge of the upper support member 51112, and optionally, the third connecting members 51118a, 51118b are respectively arranged on the two long side edges of the upper support member 51112. Through such a design, the upper support member 51112 and the side support member 51111 can be completely closed, so that the connection between the two is more reliable. Moreover, the upper support member 51112 can be completely separated from the side support member 51111 on both sides along the long side edges, so that the box body 5110 can be completely disassembled when the carrier is not used, or the upper support member 51112 can be partially separated from the side support member 51111 on either side according to needs (i.e., the degree of separation between the upper support member 51112 and the side support member 51111 is controllable, which facilitates the user to take out or put in articles from the box body 5110).

[0888] Through the above structure, when the upper support member 51112 is connected with the side support member 51111 (i.e., partially or completely connected along the side edge of the upper support member 51112 and the top edge of the side support member 51111), the body 5111 (or the box body 5110) is in an unfolded state; when the carrier is not used, the upper support member 51112 can be separated from the side support member 51111, and through the connecting structure (especially the soft connecting structure) between the sheet-shaped members 51112a, 51112b, 51112c of the upper support member 51112 and / or through the connecting structure (especially the soft connecting structure, e.g., the first connecting member 51116) between the first sub-support member 51111a and the second sub-support member 51111b of the side support member 51111, the side support member 51111 and / or the upper support member 51112 can be in a storage state, thereby reducing the space required for storage; when the carrier needs to be used again, the side support member 51111 and / or the upper support member 51112 can be unfolded and connected together. Such a design has the advantages of simple operation, low cost, small storage ...
