The present invention provides an anchoring structure A400 and an animal carrying device A1000 equipped with the anchoring structure A400. Figures 1 and 2 show perspective views of an animal carrying device A1000 according to an embodiment of the present invention.In FIG1 , the anchoring structure A400 of the animal carrying device A1000 is in a collapsed state, while in FIG2 , the anchoring structure A400 of the animal carrying device A1000 is in an engaged state. The following description of the animal carrying device A1000 will also include an explanation of the anchoring structure A400. As shown in FIG1 , the animal carrying device A1000 may be, but is not limited to, a sleeping box, a pet box, a pet carrier, a pet bag, etc. The animal carrying device A1000X has a carrying space for accommodating an animal. The animal carrying device A1000 can be fixed to a car seat or carried on the person (e.g., carried in one's hand or slung across one's back). The animal carrying device A1000 includes a base A100 and a base A200. The base A100 is positioned above the base A200, and the body A100 and base A200 together form a carrying space. The base A200 is made of, for example, a rigid material to support the body A100. The body A100 may include a fabric sheet or other material that encloses a load-bearing space. As shown in Figures 1 and 2, the body A100 comprises a front portion A140, a left side portion A120, a right side portion A130, and a rear portion A160. The front portion A140 forms the front sidewall of the load-bearing space, the left side portion A120 forms the left sidewall of the load-bearing space, the right side portion A130 forms the right sidewall of the load-bearing space, and the rear portion A160 forms the rear sidewall of the load-bearing space. In some embodiments, the bottom wall of the load-bearing space is formed by the base A200, with the front portion A140, left side portion A120, right side portion A130, and rear portion A160 directly connected to the base A200. In alternative embodiments, the body A100 comprises a bottom portion that is fixed to the base A200 and forms the bottom wall of the load-bearing space. It should be noted that, unless otherwise expressly specified or limited, directional terms such as "front," "rear," "left," and "right" regarding the animal carrying device A1000 in the embodiments of the present invention refer to the directions shown in the base diagram. Arrows L and R in the diagram schematically indicate the "left" and "right" directions, while arrows F and B schematically indicate the "front" and "rear" directions. These directional terms are used solely to clarify the description of the embodiments of the present invention and are not intended to unduly limit the scope of protection of the present invention.As shown in Figures 1 and 2, the animal carrier A1000 is equipped with a handle A180. The animal carrier A1000 has a top portion A170, which forms the top wall of the carrying space. The handle A180 is located on the top portion A170 of the body A100. This allows the animal carrier A1000 to be conveniently carried by the handle A180. As shown in Figure 3, in one embodiment, the base A200 includes a first cover A210 and a second cover A220. The first cover A210 and the second cover A220 are detachably connected. The second cover A220 forms the lower base of the base A200. The lower base of the base A200 is flat, facilitating placement of the animal carrier A1000 on a car seat. As shown in Figures 4 to 6, 18, and 19, in one embodiment, the first cover A210 and the first cover A220 together form a receiving space A203. The first cover A220 forms the bottom wall of the accommodating space A203, and the first cover A210 forms the top wall of the accommodating space A203. The anchoring structure A400 is at least partially accommodated within the accommodating space A203. This prevents the anchoring structure A400 from interfering with the load within the load space, thereby improving the comfort of the load space, and also makes the appearance of the animal carrying device A1000 more concise and beautiful. The anchoring structure A400 is suitable for connecting to a car seat to secure the animal carrying device A1000 to the car seat. As shown in Figures 3 to 5, in one embodiment, the anchoring structure A400 includes a connecting assembly A410, a locking mechanism A430, and a reset member A440 (see Figure 10). The connecting assembly A410 is used to connect to the connector of the car seat (not shown in the figures). The connecting assembly A410 is, for example, a TSOFIX connector. The connecting assembly A410 has the following different states: a locked state in which it can be locked with the connector of the car seat; The connecting assembly A410 can be in an unlocked state, detachable from the connector. When the connecting assembly A410 is not locked with the connector, it remains in the unlocked state. During the process of locking the connecting assembly A410 with the connector, the connecting assembly A410 is driven by the connector to switch to the locked state. The connecting assembly A410 is movably connected to the base A200, enabling it to switch between an extended position (also referred to as a use position) and a collapsed position. When the connecting assembly A410 is in the collapsed position, the connecting assembly A410 is in the unlocked state.As shown in Figures 4 to 6, 18, and 19, a locking mechanism A430 is connected to the connecting assembly A410. The connecting assembly A410 has a first locking position and a second locking position. The locking mechanism A430 is adapted to engage with the different locking positions to lock the connecting assembly A410 in either a collapsed position or an expanded position. When the locking mechanism A430 engages with the first locking position, the connecting assembly A410 is locked in the collapsed position; when the locking mechanism A430 engages with the second locking position, the connecting assembly A410 is locked in the expanded position. A return member A440 is disposed between the connecting assembly A410 and the base A200 to enable the connecting assembly A410 to switch to the expanded position. When the connecting assembly A410 is in the collapsed position, operating the locking mechanism A430 releases the connecting assembly A410, allowing the connecting assembly A410 to automatically retract from the collapsed position to the expanded position under the action of the return member A440 (e.g., a torsion spring). When the connecting assembly A410 is switched to the deployed position and locked, the locking mechanism A430 is operated to automatically switch the connecting assembly A410 from the locked state to the unlocked state, thereby allowing the connecting assembly A410 to be separated from the connector. When the connecting assembly A410 is switched to the deployed position and unlocked, the locking mechanism A430 is operated, and the connecting assembly A410 does not respond, which effectively means that the connecting assembly A410 remains unlocked and in the deployed position. There is at least one connecting assembly A410. The locking mechanism A430 is connected to each connecting assembly A410. As shown in Figures 7 and 8, the base A200 is provided with at least one folding space A260. When at least one connecting assembly A410 is in the folded position (i.e., when the anchoring structure A400 is in the folded state), the at least one connecting assembly A410 is accommodated within the at least one folding space A260. When the at least one connecting component A410 is in the deployed position (i.e., when the securing structure A400 is in use), the at least one connecting component A410 can extend out of the at least one folding space A260 to connect with at least one connector of the car seat. As shown in Figures 4 to 6, 18, and 19, in this embodiment, the at least one folding space A260 is formed in the first cover A210. Therefore, the connecting component A410 is not visible in Figures 4 and 5. Optionally, the base A200 is provided with a single folding space A260, and the at least one connecting component A410 is accommodated within the folding space A260; alternatively, the base A200 is provided with multiple folding spaces A260, with each connecting component A410 disposed within a corresponding folding space A260.The base A200 is also provided with a through-door A204 connecting the accommodating space A203 and at least one folding space A260, thereby allowing at least a portion of the locking mechanism A430 to pass through the through-door A204 and cooperate with the connecting component A410. The number of through-doors A204 corresponds to the number of connecting components A410. As shown in Figures 7 and 8, at least one connecting component A410 is pivotally connected to the rear of the base A200, and at least one folding space A260 is provided at the rear of the base A200. At least a portion of the locking mechanism A430 is movably provided at the front of the base A200, but is not limited thereto. The portion of the base A200 away from the connecting component A410 is the front of the base A200. This makes it easy to operate the locking mechanism A430. Specifically, the front portion of the base A200 forms the front side of the base A200, which continuously transitions with the outer side of the front side A140 of the body A100, i.e., the front side of the base A200 is at least partially flush with the outer side of the front side A140. The rear portion of the base A200 forms the rear side of the base A200, which continuously transitions with the outer side of the rear side A160 of the wooden body A100, i.e., the rear side of the base A200 is at least partially flush with the outer side of the rear side A160. Referring to Figures 1 and 2, there are two connecting assemblies A410, each of which is pivotally connected to the rear side of the base A200. There are two folding spaces A260, which are spaced apart in the left-right direction. In this embodiment, the folding space A260 is a groove recessed into the rear side of the base A200, and the opening A204 extends through the bottom wall of the folding space A260. When the two connecting assemblies A410 are in the folded position, they are respectively stored in the corresponding folding space A260. For example, the outer side of the folded connecting assembly A410 is flush with the outer side of the base A200. In other embodiments, the anchoring structure A400 may include more than two connecting assemblies A410, and the number of folding spaces A260 may also be more than two. The two or more connecting assemblies A410 can be connected to two or more connectors on the car seat. As shown in Figures 7 to 9, the two connecting assemblies A410 rotate in opposite directions to rotate from the folded position to the deployed position, or vice versa. The rotation angles of the two connecting components A410 are no greater than 90 degrees, and the rotation axes XI of the two connecting components A410 relative to the base A200 are parallel to each other.In some alternative embodiments, the two connecting assemblies A410 can rotate in the same direction to switch between the deployed and folded positions. For ease of description, the following description uses the connecting assembly A410 located on the left as an example. Referring to Figures 9 and 10, the angle θ1 between the rotation axis X1 of the connecting assembly A410 relative to the base A200 and the base A200 is acute. When the connecting assembly A410 is in the deployed position, the connecting assembly A410 is tilted downward relative to the base A200. In other words, the angle θ2 between the connecting assembly A410 and the base A200 is obtuse. This facilitates the connection of the connecting assembly A410 to the connector of the car seat. It should be noted that the angle θ1 between the rotation axis XI of the connecting assembly A410 and the base A200 refers to the angle between the rotation axis XI and the lower bottom surface of the base A200; the angle θ2 between the connecting assembly A410 and the base A200 refers to the angle between the extension direction of the connecting assembly A410 and the lower bottom surface of the base A200. As shown in Figures 4, 5, 18, and 19, in one embodiment, the locking mechanism A430 includes a locking member A431 and an operating member A432. The locking member A431 is movably disposed on the base A200 and has a locked position and a released position. The operating member A432 is operably disposed on the base A200 and is connected to the locking member A431. When the connecting assembly A410 is in different positions, the operating member A432 is operated, and the connecting assembly A410 responds differently. In other words, when the operating member A432 is operated, the connecting assembly A410 responds differently depending on the position of the connecting assembly A410. Specifically, when the connecting assembly A410 is in the folded position, operating the operating member A432 causes the connecting assembly A410 to switch from the folded position to the extended position. That is, the operating member A432 causes the locking member A431 to switch from the locked position to the unlocked position, thereby releasing the locking member A431 from the connecting assembly A410. In other words, when the operating member A432 is operated, the connecting assembly A410 switches from the folded position to the extended position corresponding to the folded position of the connecting assembly A410. When the connecting assembly A410 is in the extended position, operating the operating member A432 causes the connecting assembly A410 to switch from the locked state to the unlocked state, or remain in the unlocked state, while the connecting assembly A410 remains in the extended position. In other words, when the operating member A432 is operated, corresponding to the connection component A410 being located in the expanded position, the connection component A410 switches from the locked state to the unlocked state, or remains in the unlocked state.As shown in Figures 9 and 11 , the reset member A440 is, for example, a torsion spring. One end of the reset member A440 abuts the connecting assembly A410, while the other end is engaged with the base A200. Specifically, the base A200 is provided with a latch A205 (see Figure 18 ), which communicates with the folding space A260 (see Figure 7 ) and extends through the sidewall of the folding space A260. The reset member A440 passes through the latch A205 and engages with the sidewall of the folding space A260. As shown in Figures 4 , 5 , 9 , 18 , and 19 , in one embodiment, the locking member A431 is slidably disposed on the base A200 and moves relative to the base A200 between a locked position and a released position. The movement direction of the locking member A431 is generally parallel to the front-to-back direction. The connecting assembly A410 rotates on a plane that forms an acute angle with the horizontal. That is, the angle between the plane of rotation of the connecting assembly A410 and the horizontal plane is acute. The connecting assembly A410 rotates about the rotation axis XI relative to the base A200. The angle between the movement direction of the locking member A431 and the rotation axis XI is acute. In this embodiment, the base 200 is provided with a locking pin A206. This locking pin A206 is detachably mounted on the first cover A210 or the second cover A220 of the base A200, or fixedly mounted on the first cover A210 or the second cover A220, or integrally formed on the first cover A210 or the first cover A220. The locking member A431 is provided with a locking slot A4312 for the locking pin A206 to pass through. The locking slot A4312 extends parallel to the movement direction of the locking member A431. As shown in Figures 8 and 9, in one embodiment, the locking member A431 is provided with a locking protrusion A4311, and the first locking position is a first locking recess A4111 provided on the connecting assembly A410. The locking protrusion A4311 is adapted to engage with the first locking recess A4111. Specifically, the locking protrusion A4311 is adapted to pass through the through-hole A204 and engage with the first locking recess A4111, thereby securing the connecting assembly A410 in the collapsed position. One sidewall of the first locking recess A4111 is substantially perpendicular to the bottom wall A41112 of the first locking recess A4111 and forms an abutment wall A4111. The angle between the other sidewall of the first locking recess A4111 and the bottom wall A41112 of the first locking recess A4111 is obtuse. Referring to Figure 13, the locking protrusion A4311 includes a first portion A43111 and a second portion A43112.A step surface A43113 is formed between the second portion A43112 and the first portion A43111. A contact surface A43114 is formed on the side of the second portion A43112 facing away from the step surface A43113. This contact surface A43114 is generally parallel to the direction of movement of the locking member A431. Referring to Figure 8 , when the locking projection A4311 is locked within the first locking recess A4111, the first portion A43111 is accommodated within the first locking foot recess A4111. At this point, the contact surface A43114 abuts against the abutment wall A41111, while the step surface A43113 abuts against the outer side of the connecting assembly A410. This restricts the rotation of the connecting assembly A410, thereby locking it in the collapsed position. In other words, the flat surfaces abut against each other, making it difficult to disengage the locking projection A4311 and the first locking recess A4111 by applying external force. Therefore, even if an external force is applied to the connecting assembly A410, the connecting assembly A410 still cannot be rotated to the deployed position. As shown in Figures 7, 8, and 11, the second locking position is a second locking recess A4112 provided on the connecting assembly A410. Referring to Figure 7, when the connecting assembly A410 is in the deployed position, the second locking recess A4112 is adapted to cooperate with the locking projection A4311 to limit the position of the connecting assembly A410. Specifically, the first portion A43111 of the locking projection A4311 locks with the first locking recess A4112 to limit the position. At this point, if an external force is applied to the connecting assembly A410 to rotate it toward the folded position, the connecting assembly A410 can drive the locking member A431 to move along the unlocked position and cause the locking projection A4311 to exit the second locking recess A4112. In this embodiment, the locking engagement between the second locking recess A4112 and the locking projection A4311 allows the connecting assembly A410 to be more stably positioned in the extended position, preventing the connecting assembly A410 from being manipulated to its outermost position and thus switching to the collapsed position. Referring to Figure 7 , one sidewall of the first locking recess A4112 is formed as a guide wall A41121, and the angle between this guide wall A41121 and the bottom wall A41123 of the first locking recess A4112 is obtuse. The other, opposite sidewall of the first locking recess A4112 is formed as a push wall A41122, and the angle between this push wall A41122 and the bottom wall A41123 of the second locking recess A4112 is obtuse.The pushing wall A41122 is closer to the abutting wall A41111 of the first locking recess A4111 than the guide wall A41121. During the rotation of the connecting assembly A410 from the deployed position to the collapsed position, the pushing wall A41122 pushes the first portion A43111, causing the first portion A43111 to move along the guide wall A41121 and away from the connecting assembly A410 (i.e., toward the unlocked position). This causes the locking protrusion A4311 to exit the second locking recess A4112 and be abutted by the arcuate surface of the connecting assembly A410. When the connecting assembly A410 is rotated to the collapsed position, the locking protrusion A4311 faces the first locking recess A4111 and is no longer abutted by the arcuate surface of the connecting assembly A410. The locking member A431 automatically returns to the locked position, locking the locking protrusion A4311 with the first locking recess A4111. As shown in Figures 4 to 6, 18, and 19, the locking mechanism A430 further includes a reset member A436, which abuts against the locking member A431 to shift the locking member A431 toward the locked position. This allows the locking member A431 to automatically return to the locked position under the action of the reset member A436. The reset member A436 is, for example, a compression spring, but is not limited thereto. The reset member A436 is disposed between the locking pin A206 and the locking member A431. As shown in Figure 13, the locking member A431 is provided with a receiving groove A4313, which communicates with the locking groove A4312. In this embodiment, the projections of the receiving groove A4313 and the locking groove A4312 on a horizontal plane (i.e., on the bottom surface of the base A200) at least partially overlap. A first protrusion A4314 is provided on the end of the receiving groove A4313 away from the locking groove A4312. The reset member A436 is disposed within the accommodating groove A4313. One end of the reset member A436 is sleeved onto the first protrusion A4314, and the other end of the reset member A436 abuts the locking pin A206. This prevents displacement of the reset member A436 during compression. Returning to Figures 4 to 6, 18, and 19, in one embodiment, the locking mechanism A430 further includes a linkage member A434 and a first traction assembly A435. The operating member A432 is connected to the locking member A431 via the linkage member A434 and the first traction assembly A435. Optionally, the operating member A432 is connected to the locking member A431 via another drive structure, or the operating member A432 and the locking member A431 are directly connected, without limitation herein.Continuing to refer to Figures 4 to 6, 18 and 19, the operating member A432 is movably provided on the front portion of the base A200, and the linkage member A434 is movably connected to the base A200. The linkage member A434 is movably connected to the operating member A432 and is connected to the locking member A431 through a first traction assembly A435. When the operating member A432 moves relative to the base A200, it drives the linkage member A434 to move, and the linkage member A434 drives the locking member A431 to switch from a locked position to a released position through the first traction assembly A435. In this embodiment, the linkage member A434 is pivotally connected to the base A200. When the operating member A432 is operated, the linkage member A434 is driven to rotate. In an alternative embodiment, the linkage member A434 is movably connected to the base. When the operating member A432 is operated, it drives the linkage member A434 to move. As shown in Figures 4, 5, 6, 18 and 19, The operating member A432 is movable between a driving position and an initial position, and the moving direction of the operating member A432 is roughly parallel to the front-to-back direction. In the process of the operating member A432 moving from the initial position to the driving position, the operating member A432 drives the linkage member A434 to pivot, and the linkage member A434 drives the locking member A431 to move from the locking position to the unlocking position through the first traction component A435. In this embodiment, an operating member A432 is provided at the front of the base A200, and the operating member A432 is connected to the accommodating space A203. Specifically, the second cover body A220 of the operating member A432 is provided with an operating recess A221, and the operating member A432 passes through the side wall of the operating recess A221, so that the operating recess A221 is connected to the accommodating space A203. The operating member A432 is inserted at the operating port A222. The operating member A432 has an operating portion A4322 and an operating connection portion A4323. The operating connection portion A4323 is accommodated within the accommodating space A203 and movably connected to the linkage member A434. The operating portion A4322 is accommodated within the operating recess A221, with the operating portion A4322 protruding laterally. This allows the operating portion A4322 to be restrained within the operating recess A221 by the abutment between the sidewalls of the operating recess A221 and the operating portion A4322, preventing the operating portion A4322 from retracting within the accommodating space A203 and facilitating its forward movement.As shown in Figures 4 to 6, 18, and 19, in one embodiment, the foot locking mechanism A430 further includes a reset member A437. One end of the reset member A437 is connected to the operating member A432, and the other end is connected to the base A200. The reset member A437 provides an elastic restoring force for the operating member A432, allowing the operating member A432 to return to its initial position when not in use. Specifically, the reset member A437 is, for example, a tension spring. The operating connection portion A4323 of the operating member A432 is provided with a first hook portion A4324. The second cover A220 of the base A200 is provided with a second hook portion A208. Of course, the second hook portion A208 can also be provided on the first cover A210, and this is not limited to this application. The two ends of the reset member A437 are respectively hooked on the first hook portion A4324 and the second hook portion A208. When the operating member A432 is pulled to move from its initial position to its driven position (i.e., the operating member A432 moves forward), the reset member A437 is stretched to store energy, causing the operating member A432 to drive the linkage member A434 to rotate in the first direction about the pivot axis A207. On the other hand, when the operating member A432 is released, the operating member A432, under the action of the reset member A437, moves from its driven position to its initial position (i.e., the operating member A432 moves backward), driving the linkage member A434 to rotate in the first direction. The first direction is opposite to the first direction. As shown in Figures 4 to 6, 18, and 19, the linkage member A434 includes a connecting arm A4342, a pulling arm A4341, and a pivotal portion A4343 between the connecting arm A4342 and the pulling arm A4341. The pivotal portion A4343 is pivotally connected to the base A200. The base A200 is provided with a pivot axis A207. This pivot axis A207 extends through the pivot portion A4343 of the linkage member A434 and defines the pivot axis of the linkage member A434. The pivot axis A207 is fixedly connected to at least one of the second cover A220 and the first cover A210. In this embodiment, the pivot axis A207 is integrally formed with the second cover A220. The connecting arm A4342 is movably connected to the operating member A432, and the pulling arm A4341 is connected to the first pulling assembly A435. The connecting arm A4342 extends in a non-parallel direction to the pulling arm A4341. In this embodiment, the connecting arm A4342 is substantially perpendicular to the pulling arm A4341, and the linkage member A434 is generally shaped like a "7." The linkage member A434 is, for example, a monolithic component, but is not limited thereto.One of the operating member A432 and the linkage member A434 is provided with a connecting protrusion A43421, while the other is provided with a connecting groove A4321. The connecting protrusion A43421 is disposed in and movable within the connecting groove A4321. Movement of the operating member A432 drives the connecting protrusion A43421 within the connecting groove A4321, thereby causing the linkage member A434 to rotate relative to the base A200. As shown in Figures 4, 5, 18, and 19, in this embodiment, the linkage member A434 is rotatably disposed within the accommodating space A203. The connecting arm A4342 of the linkage member A434 is provided with a connecting protrusion A4342. The connecting protrusion A43421 is located at the end of the connecting arm A4342, which is distal to the pivoting portion A4343. Specifically, the connecting groove A4321 is provided in the operating connection portion A4323. The connecting groove A4321 extends generally in the left-right direction, meaning that the extending direction of the connecting groove A4321 is generally perpendicular to the movement direction of the operating member A432. Continuing with Figures 4, 5, 18, and 19, to limit the pivoting travel of the linkage member A434, the first cover A210 is provided with a pivot limiter A280. This pivot limiter A280 is generally fan-shaped. This pivot limiter A280 is used to limit the pivoting travel of the linkage member A434, thereby limiting the movement travel of the operating member A432. As discussed above, the first traction assembly A435 is connected between the linkage member A434 and the locking member A431. When the connecting assembly A410 is in the folded position, the movement of the linkage member A434 drives the locking member A431 in the forward and backward direction via the first pulling member A435. This releases the locking member A431 from the connecting assembly A410, and the connecting assembly A410 automatically springs out to the expanded position under the action of the return member A440. As shown in Figures 4, 5, 18, and 19, in one embodiment, the first pulling member A435 includes a first pulling member A4351, one end of which is connected to the linkage member A434 and the other end is connected to the locking member A431. In this embodiment, a first terminal A4352 and a second terminal A4353 are respectively provided at both ends of the first pulling member A4351. A first sheath A4354 is provided over the first pulling member A4351. The first sheath A4354 is positioned between the first end A4352 and the second end A4353 to prevent separation of the first sheath A4354 from the first pulling member A4351. The first pulling member A4351 may be a flexible wire such as a steel wire or a carbon fiber wire.The first terminal A4352 is detachably connected to the linkage member A434, and the second terminal A4353 is detachably connected to the locking member A431. Specifically, the traction arm A4341 of the linkage member A434 is provided with a first traction hole A43411 and a first slot A43412 connected to the first traction hole A43411 (see FIG6). The first terminal A4352 is connected to the first traction hole A43411, and the portion of the first traction member A4351 adjacent to the first terminal A4352 is confined within the first slot A43412. The locking member A431 is provided with a first connection hole A4315, and the second terminal A4353 is snapped into the first connection hole A4315. Two first limiting slots A201 are provided on the second cover A220. Optionally, the first limiting slot A201 can also be provided on the first cover A210. The two ends of the first sheath A4354 are respectively snapped into the corresponding first limiting slots A201. To ensure that the linkage member A434 can better drive the locking member A431 in the forward and backward directions when it rotates, the base A200 is equipped with a guide structure A270. This guide structure A270 is used to define the extension direction of the first pulling member A4351 and the first sheath A4354. The guide structure A270 includes a first guide portion A271 and a second guide portion A272. The first and second guide portions A271 and A272 extend along an arc and form a guide groove A273 therebetween. The guide groove A273 also extends along an arc. At least a portion of the first pulling assembly A435 extends along and is retained within the guide groove A273. It should be noted that "at least a portion of the first pulling assembly A435" should be understood as: a portion of the first pulling member A4351; or a portion of the first sheath A4354 and a portion of the first pulling member A4351. Continuing with Figures 4, 5, 18, and 19, in one embodiment, the locking mechanism A430 further includes a second pulling assembly A438, which includes a second pulling member A4381. The connecting assembly A410 is connected to the operating member A432 via the second pulling member A4381. At least a portion of the second pulling assembly A438 extends along the second guide portion A272 and is restrained by a guide protrusion A274 that protrudes laterally from the second guide portion A272. In this embodiment, the two ends of the second pulling member A4381 are respectively connected to the linkage member A434 and the connecting assembly A410, while the operating member A432 is connected to the linkage member A434. When the connecting assembly A410 is in the locked state, it is in the extended position.The operating member A432 can drive the connection assembly A410 from a locked state to an unlocked state via the second traction assembly A438. Specifically, when the connection assembly A410 is in the locked state, the operating member A432 moves relative to the base A200, causing the linkage member A434 to rotate. The linkage member A434 then drives the second traction member A4381 to move as a whole, thereby switching the connection assembly A410 from the locked state to the unlocked state. During this process, the connection assembly A410 remains in the deployed position under the action of the return member A440. When the connection assembly A410 switches to the unlocked state, because the second traction member A4381 is in a relaxed state, even if the operating member A432 moves relative to the base A200 and drives the linkage member A434 to rotate, the linkage member A434 cannot drive the first traction member A4381 to move as a whole, or can only drive it to move very slightly as a whole, causing the connection assembly A410 to remain in the unlocked state. In other words, when the connecting assembly A410 is in the unlocked state, pulling the operating member A432 forward does not switch the connecting assembly A410 between the unlocked and locked states via the second pulling member 438. Specifically, when the connecting assembly A410 is in the unlocked state, if the connecting assembly A410 is in the folded position, the operating member A432 is operated, which drives the locking member A431 toward the unlocked position via the first pulling member A435. The connecting assembly A410 automatically rotates to the deployed position under the action of the return member A440 and remains in the unlocked state. As shown in Figures 7 to 10, 18, and 19, one end of the second pulling member A438 is connected to the linkage member A434, and the other end is connected to the connecting assembly A410. In this embodiment, the second pulling member A4381 is provided with a first terminal A4382 and a second terminal A4383 at each end, respectively. A second sheath A4384 is provided over the second pulling member A4381. The second sheath A4384 is positioned between the first terminal A4382 and the second terminal A4383 to prevent separation of the second sheath A4384 from the second pulling member A4381. The second pulling member A4381 may be a flexible wire such as a steel wire or a carbon fiber wire. The first terminal A4382 is detachably connected to the linkage member A434, and the second terminal A4383 is detachably connected to the connecting assembly A410. Two first retaining grooves A202 are provided on the first cover A220. Optionally, the first retaining grooves A202 may also be provided on the first cover A210. The two ends of the first sheath A4354 are respectively engaged within the corresponding second retaining grooves A202.Specifically, the traction arm A4341 of the linkage member A434 is provided with a second traction hole A43413 and a second slot A43414, which are connected to the second traction hole A43413. The first terminal A4382 is engaged within the second traction hole A43413, and the portion of the second traction member A4381 proximal to the first terminal A4382 is confined within the second slot A43414. More specifically, the second traction hole A43413 and the first traction hole A43411 are arranged along the extension direction of the traction arm A4341, and the first slot A43414 and the first slot A43412 are located on either side of the traction arm A4341. This prevents interference between the first traction member A4351 and the first traction member A4381. The locking member A431 is provided with a limiting passage A4316 for the second pulling member A4381 to pass through. The limiting passage A4316 extends through the locking member A431 along the direction of movement of the locking member A431. The locking protrusion A4311 of the locking member A431 is at least partially located in the extension direction of the limiting passage A4316, allowing the second pulling member A4381 and the locking protrusion A4311 to enter the folding space A260 through the same through hole A204 and interact with the connecting assembly A410. Specifically, the limiting passage A4316 includes a first recess A4317 located on the side of the locking member A431 facing away from the second cover A220, a first recess A4318 located on the side of the locking member A431 facing the first cover A220, and a connecting port A4319 connecting the first recess A4317 and the first recess A4318 (see Figures 12 and 13). The locking protrusion A4311 at least partially forms the bottom wall of the second recess A4318, effectively forming a gap between the locking protrusion A4311 and the second cover A220. The second pulling member A4381 passes through this gap (i.e., below the locking protrusion A4311). As can be seen above, there are two connecting assemblies A410. As shown in Figures 4, 5, 18, and 19, the number of linkage members A434, first pulling assembly A435, and locking members A431 are correspondingly set to two. Each linkage member A434 is connected to a corresponding locking member A431 via a corresponding first pulling assembly A435. There is one operating member A432. Optionally, there may be two operating members A432, which is not a limitation in this application. The two locking members A431 correspond to the two connecting assemblies A410, respectively. Each linkage member A434 is connected to a corresponding locking member A431 via a corresponding first pulling assembly A435.The operating member A432 is connected to two linkage members A434, respectively. Movement of the operating member A432 drives the two linkage members A434 to rotate horizontally in opposite directions. Two first traction assemblies A438 are provided accordingly, with each second traction assembly A438 connected to a corresponding connecting assembly A410 and a corresponding linkage member A434. As shown in Figures 9, 10, and 11, in one embodiment, the connecting assembly A410 includes a housing A411, a latching hook A412, a latching reset member A413, and a release member A414. The housing A411 is movably mounted on the base A200. The latching hook A412 is pivotally connected to the inner cavity A4118 of the housing A411 and is configured to engage with a latching rod (not shown) of the connector of the car seat to achieve a locked connection between the connecting assembly A410 and the connector. The latch hook A412 can be switched between a locked position and an unlocked position. When the latch hook A412 is in the locked position (i.e., the connecting assembly A410 is in the locked state), the K latch hook A412 engages with the K rod K, thereby achieving a locked connection between the connecting assembly A410 and the connector. When the latch hook A412 is in the unlocked position (i.e., the connecting assembly A410 is in the unlocked state), the latch hook A412 disengages from the latch rod, thereby allowing the connecting assembly A410 and the connector to be separated. The release component A414 is movably disposed within the inner cavity A4118 of the housing A411. The release component A414 is adapted to stop the latch hook A412 to restrict the latch hook A412 in the locked position, thereby cooperating with the latch rod to achieve locked position restriction. The release component A414 is connected to the second traction assembly A438 so as to be driven to move or rotate the release component A414 via the second traction assembly A438. The locking reset member A413 is disposed between the locking hook A412 and the housing A411 to pivot the locking hook A412 toward the unlocked position. In other words, when the locking hook A412 is not blocked by the release member A414, the locking reset member A413 maintains the locking hook A412 in the unlocked position. When the locking hook A412 is in the unlocked position, the release member A414 is blocked by the locking hook A412, causing the second traction assembly A438 to be in a relaxed state. At this point, even if the operating member A432 is operated, the second traction assembly A438 cannot move the release member A414, and the locking hook A412 remains in the unlocked position. As shown in Figures 9 to 11, in one embodiment, one end of the housing A411 is pivotally connected to the rear portion of the base A200 and forms a pivot end A4113. The rotation axis XI of the housing A411 serves as the rotation axis XI of the connecting assembly A410.Both the first locking recess A4111 and the first locking recess A4112 are located at the pivot end A4113. The pivot end A4113 of the housing A411 is also provided with a receiving groove A4114, which contains a fixing protrusion A4115 extending along the rotation axis XI. A reset member A440 is sleeved onto the fixing protrusion A4115. One end of the reset member A440 abuts the sidewall of the receiving groove A4114, while the other end engages the latch A205 (see Figures 18 and 19). The housing A411 is also provided with a limiting groove A4117, located at the end of the housing A411 away from the pivot end A4113 and designed to accommodate the connector's latching rod. In this embodiment, the limiting groove A4117 and the first locking recess A4111 are located on either side of the rotation axis XI. The limiting groove A4117 is generally U-shaped. 9 and 10 , the engaging hook A412 is provided with an abutment portion A4121, which is used to cooperate with the release component A414 to maintain the engaging hook A412 in the locked position. The engaging hook A412 is pivotally connected to the inner cavity A4118 and can partially extend out of the inner cavity A4118. The engaging hook A412 is provided with an engaging groove A4122. When the engaging hook A412 is in the locked position, the engaging hook A412 at least partially extends into the limiting groove A4117 to close the notch of the limiting groove A4117. The notch of the engaging groove A4122 is closed by the side wall or bottom wall of the limiting groove A4117, thereby achieving locking and limiting of the latch rod. When the locking hook A412 is in the unlocked position, the notches of the limiting groove A4117 and the locking groove A4122 are both open, allowing the locking rod to disengage from the locking hook A412. Specifically, the locking groove A4122 is U-shaped, with two opposing walls forming a locking wall A4123 and a push wall A4124. The push wall A4124 is adapted to be pushed by the X-rod to drive the locking hook A412 to pivot from the unlocked position to the locked position. A portion of the locking hook A412 is housed within the inner cavity A4118 and is pivotally connected to the sidewalls of the inner cavity A4118 via a pivot pin A417. When the locking hook A412 is in the locked position, the locking wall A4123 is located within the limiting groove A4117 and closes the notch of the limiting groove A4117. When the engaging hook A412 is in the unlocked position, the pushing wall A4124 is located in the limiting groove A4117, and the locking wall A4123 retracts into the inner cavity A4118. Therefore, when the connecting assembly A410 is locked with the lever, the lever can push the locking wall A4123 to pivot the engaging hook A412 from the unlocked position to the locked position.

[0007] The locking reset member A413 is, for example, a torsion spring. The locking reset member A413 is housed within the inner cavity A4118 and sleeved onto the pivot pin A417. One end of the locking reset member A413 abuts the inner wall of the inner cavity A4118, while the other end engages the latching notch A4125 of the latching hook A412. As shown in Figures 9 and 10, in one embodiment, the release component A414 is slidably disposed within the housing A411. The release component A414 includes a release block A4141 and a limiting rod A4142 disposed adjacent to the release block A4141. The release block A4141 is slidably disposed within the inner cavity A4118 and can drive the limiting rod A4142 to move. The limiting rod A4142 is adapted to abut against the abutting portion A4121. Specifically, the release block A4141 moves between a first position and a second position. When the release block A4141 is in the first position, the limiting rod A4142 abuts against the abutment A4121, thereby limiting the K-hooking hook A412 in the locked position. When the release block A4141 is in the first position, the limiting rod A4142 disengages from the abutment A4121, and the release block A4141 is abutted by the abutment A4121, maintaining the second position. At this point, the second pulling member A438 is in a relaxed state. Optionally, the limiting rod A4142 can be detachably mounted on the release block A4141±, fixedly mounted on the release block A4141±, or integrally formed with the release block A4141. As shown in Figures 9, 10, and 14, in this embodiment, the limiting rod A4142 is disposed through the release block A4141. The release block A4141 is provided with a first groove A41413, within which a portion of the limiting rod A4142 is located. The notch of the first groove A41413 faces the engaging hook A412. Referring to Figure 9, when the release block A4141 is in the first position, the abutment portion A4121 of the engaging hook A412 extends into the first groove A41413 and abuts the limiting rod A4142. The first groove A41413 has two opposing sides, through which the limiting rod A4142 extends. Referring to Figure 10, when the engaging hook A412 is in the unlocked position, the abutment portion A4121 abuts against the side of the first groove A41413, thereby limiting the release block A4141 in the second position. As shown in Figures 9 and 10, in one embodiment, the release block A4141 is slidably connected to the housing A411 through a sliding pin A415. The release block A4141 is provided with a sliding groove A4141L for the sliding pin A415 to pass through. The sliding groove A41411 extends linearly, and both ends of the sliding pin A415 are fixedly connected to the housing A411.A release reset member A416 is disposed between the release block A4141 and the sliding pin A415. This member is configured to bias the release block A4141 toward the engaging hook A412. Specifically, the release reset member A416 is configured to bias the release block A4141 toward the second position. Specifically, the release reset member A416 is configured to be a repulsive spring. A second protrusion A41412 is disposed within the sliding groove A41411. The release reset member A416 is received within the sliding groove A41411. One end of the release reset member A416 is sleeved onto the second protrusion A41412, while the other end abuts the sliding pin A415. The release block A4141 is connected to the first traction assembly A438. Specifically, the release block A4141 is provided with a second connection hole A41415. The first connection hole A41415 is provided perpendicular to the movement direction of the release block A4141 and extends through the release block A4141. The first connection hole A41415 is located at the end of the release block A4141 away from the limiting rod A4142. This means that the second connection hole A41415 and the first groove A41413 are located at opposite ends of the release block A4141. The second terminal A4383 of the second pulling assembly A438 engages with the second connection hole A41415. As shown in FIG15 , the release block A4141 is also provided with a second groove A41414, which communicates with the second connection hole A41415. The portion of the second pulling member A4381 proximate the second connecting hole A41415 extends along the second groove A41414 and is retained within the first groove A41414. The following describes the operating principles of the animal carrying device A1000 and its anchoring structure A400 according to the present invention, with reference to Figures 4, 5, 7 to 10, 18, and 19. As shown in Figure 8, when the two connecting assemblies A410 are in the collapsed position, they are in an unlocked state (i.e., each engaging hook A412 is in the unlocked position). Each connecting assembly A410 is accommodated within the corresponding collapsed space A260. Each locking member A431 is in a locked position, locked with the first locking recess A4111 of the corresponding connecting assembly A410. Each release block A4141 is abutted by the end surface of the abutting portion A4121 of the engaging hook A412 and retained in the second position.When connecting assembly A410 to the connector, first unfold assembly A410. Referring to Figures 4, 5, 18, and 19, pull operating member A432 forward, causing two linkage members A434 to rotate horizontally in opposite directions. Each linkage member A434, through its corresponding first traction member A435, drives its corresponding locking member A431 from a locked position to a released position, thereby causing assembly A410 to spring from its collapsed position to its unfolded position under the action of reset member A440. During this process, assembly A410 remains unlocked, meaning that hook A412 remains in the unlocked position. The connector for the car seat is then connected to assembly A410. The abutting wall A4124 of hook A412 is pushed against the connector's latching rod, causing hook A412 to rotate from the unlocked position to the locked position, overcoming the force of reset member A413. When the locking hook A412 rotates to the locked position (i.e., the locking rod is locked in place), the end surface of the abutment portion A4121 of the locking hook A412 no longer abuts the release block A4141. Under the action of the release reset member A416, the release block A4141 moves from the first position (see Figure 10) (i.e., toward the locking hook A412) to the first position (see Figure 9), driving the limiting rod A4142 to move. When the release block A4141 moves to the first position (see Figure 9), the limiting rod A4142 abuts the side surface of the abutment portion A4121, thereby retaining the locking hook A412 in the locked position. To fold the connecting assembly A410, the connecting assembly A410 is first separated from the connector. Referring to Figures 4, 5, 18, and 19, pulling the operating member A432 forward causes the two linkage members A434 to rotate horizontally in opposite directions. Each linkage member A434, through its corresponding first traction assembly A438, drives the corresponding release block A4141 of the connecting assembly A410 from the first position (see Figure 9) to the second position (see Figure 10), away from the engaging hook A412. During this process, the limiting rod A4142 gradually disengages from the abutment portion A4121 of the engaging hook A412, and the engaging hook A412 automatically rotates from the locked position to the unlocked position under the action of the engaging return member A413. When the engaging hook A412 rotates to the unlocked position (i.e., the connecting assembly A410 is unlocked and separated from the connecting head), the operating member A432 is released. The operating member AA432 automatically returns to the initial position under the action of the reset member A437 and drives the linkage member A434 to rotate in the opposite direction to reset.At this point, the release block A4141 is abutted by the end surface of the abutment portion A4121 and is restrained in the second position. During the separation of the connecting assembly A410 from the connector, the locking recess A4311 of the locking member A431, driven by the first pulling assembly A435, exits the first locking recess A4112. Then, under the action of the reset member A436, it moves to the locked position and engages with the second locking recess A4112. The connecting assembly A410 remains in the deployed position under the action of the reset member A440. After the separation of the connecting assembly A410 from the connector, the two connecting assemblies A410 are rotated in opposite directions toward the collapsed position. The locking protrusion A4311 of the locking member A431, under the action of the push wall A41122 of the second locking recess A4112, exits the first locking recess A4112 along the guide wall A41121 and abuts against the outer side surface of the housing A411 (i.e., the outer side surface of the ISOFXI connector assembly). When the connecting assembly A410 is rotated to the folded position, the locking recess A4311 is no longer abutted by the outer surface of the housing A411. The locking protrusion A4311 faces the first locking recess A4111. Under the action of the reset member A436, the locking member A431 automatically moves to the locked position, causing the locking protrusion A4311 to engage with the first locking recess A4111, thereby locking the connecting assembly A410 in the folded position. Figures 20 to 23 illustrate the structure of a wheeled mobile device B1000 according to a first embodiment of the present invention. The wheeled mobile device B1000 may include a frame B100, a carrier B300, and a support assembly B200 according to some embodiments of the present invention. The support assembly B200 will be described below in conjunction with the description of the wheeled mobile device B1000. In the embodiment shown in FIG20 , the wheeled mobile device B1000 is described using a stroller as an example. Depending on the type of carrier B300, the stroller can be a child stroller, a pet stroller, a shopping cart, or the like. Of course, in some embodiments, the wheeled mobile device B1000 can also be other types of products. Referring to the structure of the frame B100 shown in FIG21 , in some embodiments, the frame B100 is generally bilaterally symmetrical. The frame B100 may include, for example, a front support bar B110, a rear support bar B120, an upper support bar B130, and a handrail B140. The frame B100 may be foldable or non-foldable, without limitation in this application.It should be noted that, unless otherwise expressly specified or limited, directional terms such as "front," "rear," "left," and "right" regarding the wheeled mobile device B1000 in various embodiments of the present invention are based on the "front," "rear," "left," and "right" directions of the wheeled mobile device B1000 during normal operation. Arrows F and B schematically indicate the "front" and "rear" directions, and arrows L and R schematically indicate the "left" and "right" directions. These directional terms are intended solely to clarify the description of the embodiments of the present invention and are not intended to unduly limit the scope of protection of the present invention. Referring to FIG. 21 , the front support bar B110, for example, has a U-shaped structure and includes two rods Bill located on left and right sides and a front crossbar B112 connected between the two rods Bill. The front crossbar B112 extends generally in the left-right direction. At least one front wheel B151 is mounted at the bottom of the front support bar B110. In this embodiment, two front wheels B151 are mounted on the bottom of the front support bar B110, spaced apart in the left-right direction. More specifically, the two front wheels B151 are mounted on the left and right ends of the front crossbar B112. The front wheels B151 can be universal wheels or non-universal wheels. Of course, in alternative embodiments, the front support bar B110 can have other configurations. For example, the front support bar B110 can have a V-shaped or T-shaped structure, with one front wheel B151 mounted centrally at the bottom of the front support bar B110. The rear support bar B120 can have a U-shaped structure, for example, including two rods B121 on the left and right sides and a rear crossbar B122 connecting the two rods B121. The upper ends of each rod B121 are connected to the upper ends of the rods B111 of the front support bar B110 on the same side, for example, via connecting portions B118. The rods B1 and B121 on the same side together with the ground form a roughly triangular structure. The rear support rod B120 is equipped with two rear wheels B152, spaced apart in the left-right direction. The rear wheels B152 can be universal or non-universal. In this embodiment, the rear wheels B152 are larger than the front wheels B151 to enhance the overall stability of the wheeled mobile device B1000. Of course, in alternative embodiments, the rear wheels B152 can be the same size as the front wheels B151. The upper support rod B130 includes two rods B131 on the left and right sides. The lower end of each rod B131 is connected to the connecting portion B118 on the same side, and the upper end of each rod B131 is connected to the armrest B140.In some embodiments, the armrest B140, for example, has a U-shaped structure, with its two ends connected to the rods B131 of the upper support rod B130 on the same side. In some embodiments, the two ends of the armrest B140 are connected to the two rods B131, for example, via a telescoping structure, to enable adjustment of the height of the armrest B140. The carrier B300 may be, for example, a pet sleeping box, an infant carrier, an infant sleeping cot, or an infant seat. Referring to Figures 20 and 23 , the carrier B300 is described as a pet sleeping box. The carrier B300 includes a body B310, a base B320, and an anchoring structure. The body B310 is positioned above the base B320 and, together with the base B320, forms a carrying space B302. The body B310 may include a foam material or other rigid material that encloses the carrying space B302. The base B320 may be made of, for example, a hard material to support the body B310. As shown in Figures 24 and 25 , in one embodiment, the anchoring structure includes an anchor assembly B330, which is, for example, an ISOFIX connection assembly. Of course, in other embodiments, the anchor assembly B330 may be other suitable connection assemblies, and this application is not limited thereto. Continuing with Figures 24 and 25 , the anchor assembly B330 is mounted on the base B320 and includes a housing B331 and a snap hook B332. As shown in Figure 20 , the anchoring structure also includes an operating member B334. The anchor assembly B330 can be movably mounted on the base B320 or fixedly mounted thereto and is provided with a generally U-shaped receiving groove B3311. Preferably, the housing B331 is movably mounted on the base B320 and is provided with the receiving groove B3311. The engaging hook B332 has an engaging groove B3323, with opposing sides formed into a hook portion B3321 and a push portion B3322. The engaging hook B332 is pivotally connected to the inner cavity of the housing B331 and is rotatable between an unlocked position and a locked position. As shown in Figure 25, when the engaging hook B332 is in the locked position, the hook portion B3321 extends into the receiving groove B3311 and closes the notch of the receiving groove B3311, achieving a locked position. 24 , when the engaging hook B332 is in the unlocked position, the notches of the accommodating groove B3311 and the K-engaging groove B3323 are both open, the K hook portion B3321 retracts from the accommodating groove B3311, and the pushing portion B3322 extends into the accommodating groove B3311, allowing the F hook portion B3321 to switch from the unlocked position to the locked position by pushing the pushing portion B3322.The operating member B334 is used to unlock the engaging hook B332, allowing it to rotate from the locked position to the unlocked position. In this embodiment, the operating member B334 is movably mounted on the base B320 and operable. Specifically, the operating member B334 is mounted on the front side of the base B320, while the anchor assembly B330 is mounted on the rear side of the base B320. Of course, in alternative embodiments, the operating member B334 may be movably mounted on the anchor assembly B310, for example. Referring to Figures 20 and 23 , for example, there are two anchor assemblies B330 and one operating member B334, but this is not limiting. The two anchor assemblies B330 are each pivotally connected to the base B320 and can rotate relative to the base B320 in a substantially horizontal direction about a rotation axis X2 (see Figure 24). Specifically, the two anchor assemblies B330 can rotate relative to the base B320 on a plane slightly inclined to the horizontal (i.e., the surface on which the base B320 is placed). In this embodiment, the two anchor assemblies B330 rotate in opposite directions from a folded position to an extended position, or vice versa. Of course, in alternative embodiments, the two anchor assemblies B330 can also rotate in the same direction from a folded position to an extended position, or vice versa. It should be noted that the anchor assemblies B330 being pivotally connected to the base B320 means that the housing B331 of the anchor assemblies B330 is pivotally connected to the base B320. In this embodiment, the base B320 is provided with a folding space B301, which is a recessed groove formed on the rear side of the base B320. When the two anchor assemblies B330 are in the folded position, the two anchor assemblies B330 are respectively stored within the folding space B301. For example, the outer side of the folded anchor assembly B330 is flush with the rear side of the base B320 or recessed relative to the rear side of the base B320. As shown in Figures 20 and 21, the support assembly B200 is mounted on the vehicle frame B100 and is suitable for mounting the vehicle B300. In this embodiment, the support assembly B200 is fixedly (i.e., non-removably) mounted on the vehicle frame B100. The specific structure for achieving the connection between the support assembly B200 and the vehicle frame B100 will be described in detail later. In other embodiments, the support assembly B200 can also be removably mounted on the vehicle frame B100. Referring to Figures 21, 24, and 25, the support assembly B200 includes a support frame B210 and a locking member B22. The support frame B210 is suitable for supporting the vehicle B300 and is provided with a connecting slot B212, which is suitable for receiving the anchor assembly B330 of the vehicle B300.The engaging member B22 is provided on the support frame B210 and is at least partially accommodated within the connecting groove B212. It is adapted to engage with the anchor assembly B330 to restrict the forward and backward movement of the anchor assembly B330 relative to the support assembly B200, thereby at least partially locking the anchor assembly B330 within the connecting groove B212. Specifically, the engaging member B22 is, for example, a locking pin B220. The anchor assembly B330 is provided with a locking hook B332. The locking pin B220 penetrates the support frame B210 and is adapted to engage with the locking hook B332 of the anchor assembly B330. As shown in FIG22 , the support frame B210 has a generally rectangular structure and includes a first bracket B21A and a second bracket B21B. The first bracket B21A and the second bracket B21B are connected by mounting bases B230 on the left and right sides. Specifically, the first bracket B21A and the second bracket B21B are roughly U-shaped. The two ends of the first bracket B21A are connected to two mounting blocks B230, respectively, while the two ends of the first document holder B21B are connected to two mounting blocks B230, respectively. The two mounting blocks B230 are respectively provided on the left and right sides of the support frame B210. Optionally, the first bracket B21A and the second bracket B21B are pivotally connected via the mounting blocks B230 to facilitate folding the support frame B210. In other embodiments, the first bracket B21A and the second bracket B21B may also be fixedly connected. In still other embodiments, at least one of the first bracket B21A and the second bracket B21B may be retractable in the front-to-back direction relative to the two mounting bases B230 to adjust the front-to-back dimension of the support frame B210. This facilitates the adaptation of the support frame B210 to vehicles B300 of different sizes. The support frame B210 has a support plane B213, which is formed by the first bracket B21A and the first bracket B21B. The second bracket B21A is provided with a receiving protrusion B214 that protrudes upward from the support plane B213. This receiving protrusion B214 is provided with a connecting groove B212, the opening of which faces the second bracket B21B. In this embodiment, the second bracket B21B is located in front of the first bracket B21A, with the opening of the connecting groove B212 facing forward. In some alternative embodiments, the first bracket B21B may be positioned rearward of the first bracket B21A, with the opening of the connecting slot B212 facing rearward. This is not a limitation of the present application. As shown in FIG21 and FIG23 , the number of connecting slots B212 corresponds to the number of anchor assemblies B330. Specifically, the number of connecting slots B212 is, for example, two.As shown in Figures 24 and 25 , each connecting slot B212 includes a first slot portion B2121 and a second slot portion B2122. The first slot portion B2121 is further from the slot opening of the connecting slot B212 than the second slot portion B2122. The extension direction of the first slot portion B2121 is parallel to the insertion direction W1 of the anchor assembly B330 inserted into the connecting slot B212. The insertion direction W1 of the anchor assembly B330 is parallel to the extension direction of the anchor assembly B330 when in the deployed position. In this embodiment, the support plane B213 is substantially parallel to the placement surface (i.e., the horizontal plane) of the base B320 and forms an obtuse angle with the insertion direction W1 of the anchor assembly B330 inserted into the connecting slot B212 (described below). Specifically, when the anchor assembly B330 is inserted into the connecting slot B212, the anchor assembly B330 extends obliquely relative to the support plane B213. In this way, the outer sidewall B2123 of the first groove portion B2121 can further restrict the front-to-back movement of the anchor assembly B330 by blocking it. Continuing with Figures 24 and 25, the shape of the connecting groove B212 matches the shape of the outer shell B331 of the anchor assembly B330, and the sidewalls of at least one of the first groove portion B2121 and the first groove portion B2122 are adapted to at least partially mate with the outer surface of the anchor assembly B330. Specifically, when the anchor assembly B330 is inserted into the connecting groove B212, the left and right sidewalls of the first groove portion B2121 mate with the left and right sidewalls of the outer shell B331, respectively, and the upper and lower sidewalls B2123 of the first groove portion B2121 mate with the upper and lower sidewalls of the outer shell B331, respectively. This securely connects the anchor assembly B330 to the connection slot B212, preventing the anchor assembly B330 from moving upward, horizontally, leftward, or rightward relative to the support frame B210, thereby preventing the carrier B300 from moving relative to the support frame B210. Furthermore, it guides the anchor assembly B330 into engagement with the connection slot B212 along the insertion direction W1. The upper sidewall of the first slot portion B2122 is coplanar with the upper sidewall of the first slot portion B2121 and parallel to the insertion direction W1. The lower sidewall B2124 of the second slot portion B2122 is coplanar with the support plane B213, and the lower sidewall B2123 of the first slot portion B2121 is parallel to the insertion direction W1. The included angle 63 between the lower side wall B2124 of the second groove portion B2122 and the lower side wall B2123 of the first groove portion B2121 is an obtuse angle, that is, the included angle between the supporting plane B213 and the plugging direction W1 is an obtuse angle.As shown in Figures 21, 24, and 25, in one embodiment, the extending direction of the locking pin B220 is perpendicular to the insertion direction W1 of the anchor assembly B330 into the connecting slot B212. The locking pin B220 is spaced apart from the bottom of the connecting slot B212. Optionally, the spacing distance D between the locking pin B220 and the bottom of the connecting slot B212 satisfies the following conditions: when the locking pin B220 and the extended hook B332 are engaged (see Figure 25), the end of the anchor assembly B330 contacts the bottom of the connecting slot B212 or is spaced apart from the bottom of the connecting slot B212. In other words, the spacing distance D between the locking pin B220 and the bottom of the connecting slot B212 is greater than or equal to the distance between the locking slot B3323 of the locking hook B332 and the end of the housing B331. When the anchor assembly B330 is inserted into the connection slot B212 along the insertion direction W1, the engaging pin B220 pushes against the engaging hook B332, causing it to rotate from the unlocked position (see FIG. 24 ) to the locked position (see FIG. 25 ), thereby engaging the engaging pin B220 with the engaging hook B332. In this embodiment, when the anchor assembly B330 is not inserted into the connection slot B212 (see FIG. 24 ), the engaging hook B332 remains in the unlocked position. When the anchor assembly B330 is inserted into the connection slot B212, the engaging pin B220 pushes against the pushing portion B3322 of the engaging hook B332, causing the engaging hook B332 to rotate from the unlocked position to the locked position and engage with the engaging pin B220. At this point, the engaging hook B332 is held in the locked position by a retaining assembly B333 disposed within the housing B331. When the anchor assembly B330 needs to be separated from the support frame B210, the operating member B334 is operated, which drives the retaining assembly B333 away from the engaging hook B332, releasing the retaining assembly B333's stop on the engaging hook B332. The engaging hook B332 then automatically rotates to an unlocked position under the action of a reset member B335 (e.g., a torsion spring) and separates from the retaining pin B220. The carrier B300 can now be moved in a direction opposite to the insertion direction W1 until the anchor assembly B330 is completely removed from the connecting slot B212, thereby separating the carrier B300 from the support assembly B200. As shown in FIG22 , in one embodiment, the vehicle frame B100 is provided with two connecting bases B190, for example. The two connecting seats B190 are respectively detachably connected to, or fixedly provided with, or integrally formed on the corresponding connecting portion B118 of the vehicle frame B100 (ie, on the same side).The two mounting blocks B230 are adapted to engage with corresponding connecting blocks B190. The support assembly B200 also includes a locking mechanism B240 adapted to connect with the mounting blocks B230 and connecting blocks B190 on the same side, respectively, to lock the mounting blocks B230 to the connecting blocks B190. For ease of description, the following uses the mounting blocks B230, locking mechanism B240, and connecting blocks B190 located on the same side as an example. One of the connecting base B190 and the mounting base B230 is provided with a mounting groove B235. The mounting groove B235 has a notch for inserting the other of the connecting base B190 and the mounting base B230 into the mounting groove B235. The other of the connecting base B190 and the mounting base B230 is provided with a connecting protrusion B192. At least a portion of the connecting protrusion B192 is adapted to be inserted into the mounting groove B235 through the notch of the notch, thereby engaging the connecting base B190 and the mounting base B230. As shown in FIG. 22 , in this embodiment, the mounting base B230 is provided with the mounting groove B235. The connecting protrusion B192 of the connecting base B190 can engage with the mounting groove B235 through the notch of the notch. Of course, in an alternative embodiment, the connecting base B190 may be provided with a mounting slot B235, and the mounting base B230 may be engaged with the mounting slot B235 via the slot B235. Continuing with FIG22 , in one embodiment, the mounting slot B235 is generally U-shaped, with the notch of the mounting slot B235 facing downward, so that the mounting base B230 engages with the connecting base B190 in a vertical direction (i.e., vertical direction). That is, the engagement direction W2 of the mounting base B230 and the connecting base B190 is generally parallel to the vertical direction. By configuring the mounting base B230 and the connecting base B190 to be tightly engaged, the mounting base B230 can be prevented from separating or becoming loose from the mounting base due to inertia during movement of the wheeled mobile device B1000. Of course, in an alternative embodiment, the notch of the mounting slot B235 can face forward or backward, or toward the lower left or lower right, etc., and this is not limited herein. In one embodiment, for example, in the first embodiment shown in FIG. 22 and the second embodiment shown in FIG. 26 to FIG. 28 , although the structures of the support assembly B200 are different, the mounting base B230 and locking mechanism B240 of the support assembly B200 in the first embodiment have the same structure as the mounting base B230 and locking mechanism B240 of the support assembly B200 in the second embodiment. The locking mechanism B240 includes a locking member B241, a return member B243, and a locking hole B244.The reset member B243 is not shown in FIG. 22 , but is shown in FIG. 27 . The locking member B241 is movably disposed on one of the mounting base B230 and the connecting base B190 and is capable of switching between a locked position and a released position. A locking hole B244 is disposed on the other of the mounting base B230 and the connecting base B190. The locking member B241 includes a locking portion B2411 adapted to engage with the locking hole B244. When the locking member B241 is in the locked position, at least a portion of the locking member B241 extends into the locking hole B244 to prevent the mounting base B230 from separating from the connecting base B190, thereby locking the mounting base B230 to the connecting base B190. When the locking member B241 is in the unlocked position, the locking portion B2411 at least partially retracts into the mounting base B230, disengaging the locking portion B2411 from the locking hole B244, thereby allowing the mounting base B230 to separate from the connecting base B190. The resetting member B243 is adapted to provide a force to the locking foot member B241, thereby moving the locking member B241 toward the locked position. Optionally, there are two locking mechanisms B240: a first locking mechanism B240A and a second locking mechanism B240B. Of course, in some alternative embodiments, the number of locking mechanisms B240 may be one or more than two, and this is not a limitation of the present invention. As shown in FIG22 , the locking member B241A of the first locking mechanism B240A is movably disposed on the mounting base B230, while the locking hole B244A of the first locking mechanism B240A is disposed on the connecting base B190. Specifically, the locking member B241A of the first locking mechanism B240A is movably mounted on the mounting base B230, and a locking foot B2411 of the locking member B241A can extend beyond the mounting base B230. More specifically, the locking member B241A is movable relative to the mounting base B230 along a first direction D1, where the first direction D1 is substantially parallel to the left-right direction. The locking member B241B of the second locking mechanism B240B is movably mounted on the connecting base B190, and a locking hole B244B of the second locking mechanism B240B is disposed within the mounting base B230. Specifically, the locking member B241B of the second locking mechanism B240B is movably mounted on the connecting base B190, and a locking portion B2411 of the locking member B241B can extend beyond the connecting base B190.More specifically, the movement direction of the locking member B241B is parallel to the movement direction of the locking member B241A. That is, the locking member B241 can move relative to the connecting base B190 in the first direction D1. The locking member B241B and the locking member B241A move in opposite directions from the locked position to the released position, or vice versa. In this embodiment, the locking member B241A of the first locking mechanism B240A and the locking holes B244B of the second locking mechanism B240B are vertically distributed on the mounting base B230. Specifically, the locking member B241A of the first locking mechanism B240A is located above the mounting groove B235, while the locking hole B244B of the first locking mechanism B240B is located below the locking member B241A of the first locking mechanism B240A and below or above the opening of the mounting groove B235. As shown in Figures 22 and 27, in some embodiments, the mounting base B230 includes a first base body B231 and a second base body B232. The second base body B232 is connected to the support frame B210. The first base body B231 is detachably connected to the side of the second base body B232 facing away from the support frame B210 (i.e., the outward side of the second base body B232). The first base body B231 and the second base body B232 are detachably connected. At least a portion of the locking member B241A of the first locking mechanism B240A is trapped between the first base body B231 and the second base body B232. The first base body B231 is provided with an exit passage B239, which is adapted to be inserted and engaged by the locking member B241A and to define the movement direction of the locking member B241A. As shown in Figures 22, 27, and 28, in some embodiments, the locking member B241A further has a limiting protrusion B2412. The locking member B241A has a roughly T-shaped structure. The locking member B241A's retaining protrusion B2412 is retained between the first base B231 and the second base B232, and the locking portion B2411 of the locking member B241A can extend beyond the first base B231 through the passage B239. The retaining protrusion B2412 is provided with a sliding groove B2413 that extends through the retaining protrusion B2412 along the direction of movement of the locking member B241A. Optionally, there are two sliding grooves B2413, symmetrically disposed on the locking member B241A. A guide protrusion B2311 is provided on the side of the second base B231 facing the second base B232, which slidably engages with the sliding groove B2413.The sliding engagement between the guide protrusion B2311 and the slide groove B2413 further restricts the movement of the locking member B241A to a predetermined direction, preventing the locking member B241A from deflecting during movement. Optionally, the sidewalls of the slide groove B2413 are provided with guide ribs B2414 extending in the direction of movement of the locking member B241A. The guide protrusion B2311 is provided with guide grooves B2312, with which the guide ribs B2414 slidably engage. In this embodiment, multiple sets of sliding engagements are used to better restrict the movement of the locking member B241A to a predetermined direction. The ends of the guide grooves B2312 are formed to abut against surfaces B2313, so that the locking member B241A can be stopped by the abutment surfaces B2313. This limits the sliding travel of the locking member B241A relative to the first base B231. Referring to Figures 27 and 28, the reset member B243A of the first locking mechanism B240A is disposed between the locking member B241A of the first locking mechanism B240A and the mounting base B230, and provides a force to the locking member B241A, thereby moving the locking member B241A toward the locked position. In other words, the force of the reset member B243A allows the locking member B241A of the first locking mechanism B240A to remain in the locked position. In this embodiment, the reset member B243A is, for example, a compression spring. The reset member B243A is disposed within the mounting base B230, specifically between the locking member B241A and the second base B232. One end of the reset member B243A abuts the second base B232, while the other end abuts the locking member B241A. The reset member B243A can be provided with a receiving groove B2416, with the end of the reset member B243A facing away from the second base body B232 being received within the receiving groove B2416. The second base body B232 can be provided with a limiting protrusion B2321, with the end of the reset member B243A facing away from the locking member B241 being sleeved onto the limiting protrusion B2321. This prevents the reset member B243A from shifting during elastic energy storage (e.g., compression) or release. As shown in FIG22 , the locking portion B2411 of the locking member B241A is provided with a wedge-shaped surface B2415A. During the connection between the support assembly B200 and the vehicle frame B100, that is, during the engagement between the mounting base B230 and the connecting base B190, the wedge-shaped surface B2415A of the locking member B241A is pushed against the mounting base B230, causing the locking member B241A to move from a locked position to a released position.When the mounting base B230 is fully engaged, the locking member B241A aligns with the locking hole B244A. The wedge-shaped portion B2415A of the locking member B241A is no longer resisted by the connecting base B190. Under the force of the reset member B243A, the locking member B241A moves from the locked / released position to the locked position, allowing the locking portion B2411 of the locking member B241A to extend into the locking hole B244A and remain within the locking hole B244A under the force of the reset member B243A. In this embodiment, the support assembly B200* is provided with a release mechanism that can drive the locking foot member B241A from the locked position to the released position. Therefore, the support assembly B200 cannot be removed from the vehicle frame B100* after being installed to the vehicle frame B100*. Of course, in other embodiments, the support assembly B200 may be provided with a release mechanism capable of driving the locking member B241A to switch from a locked position to a released position, that is, the support assembly B200 may be detachably connected to the vehicle frame B100. This will be described in detail in the embodiments below. Referring to FIG. 22 , the second locking mechanism B240B has a similar structure to the first locking mechanism B240A described above. The locking member B241B of the second locking mechanism B240B can be disposed on the connecting base B190 in a manner similar to the locking member B241A of the first locking mechanism B240A described above. Similarly, the reset member (not shown) of the second locking mechanism B240B can be disposed on the connecting base B190 in a manner similar to the reset member B243A of the first locking mechanism B240A described above, which will not be described in detail here. Of course, in alternative embodiments, the reset member and locking member B241B of the first locking mechanism B240B can be disposed on the connecting base B190 in other suitable manners, which are not limited by this application. As shown in Figures 22 and 24 , the locking portion B2411 of the locking member B241B is also provided with a wedge-shaped surface B2415B. This wedge-shaped surface B2415B of the locking member B241B is disposed substantially opposite the wedge-shaped surface B2415B of the locking member B241A. Specifically, the wedge-shaped surface B2415B of the locking member B241A is disposed substantially downward, while the wedge-shaped surface B2415B of the locking member B241B is disposed substantially upward. During engagement between the mounting base B230 and the connecting base B190, the mounting base B230 is adapted to push against the wedge-shaped surface B2415B provided on the locking member B241B of the first locking mechanism B240B, causing the locking member B241B of the second locking mechanism B240B to be abutted and restrained in the released position.When the mounting base B230 and the connecting base B190 are engaged, the locking portion B2411 of the locking member B241B aligns with the locking hole B244B and, under the action of the reset member of the second locking mechanism B240B, extends into the locking hole B244B, further preventing the mounting base B230 from separating from the connecting base B190. Figure 26 illustrates a schematic structural diagram of a wheeled mobile device B1000 according to a second embodiment of the present invention. Figures 29 to 32 illustrate schematic structural diagrams of a wheeled mobile device B1000 according to a second embodiment of the present invention. In some embodiments, as shown in Figures 26 and 29, the wheeled mobile device B1000 includes a frame B100, a carrier B300, and a support assembly B200. The carrier B300 of the first embodiment is not shown in Figure 26; its structure can be compared to the structure of the carrier B300 of the second embodiment shown in Figures 29 to 32. The carrier B300 is adapted for detachable connection to the support assembly B200. The detachable connection between the vehicle B300 and the support assembly B200 will be described in detail later. The vehicle frame B100 can refer to the vehicle frame B100 in the first embodiment described above and will not be described in detail here. The support assembly B200 of the wheeled mobile device B1000 in this embodiment differs from the support assembly B200 of the wheeled mobile device B1000 in the first embodiment described above in at least the following ways. As shown in Figures 26 and 27, the support assembly B200 includes a first bracket B21A and a first bracket B21B, and the first bracket B21A is pivotally connected to the second bracket B21B via a mounting base B230. The connecting portion B118 of the vehicle frame B100 is provided with a connecting base B190 suitable for engaging with the mounting base B230. The specific structure of the connecting base B190 can refer to the structure of the connecting base B190 in the first embodiment described above. The mounting base B230 includes a first pivoting base B233 and a second pivoting base B234 that are pivotally connected to each other. The first bracket B21A is connected to the first pivoting base B233, and the second bracket B21B is connected to the second pivoting base B234, allowing the support frame B210 to be folded. The mounting base B230 also includes a first base B231 and a first base B232 that can interlock with each other. The first base B232 is connected to the first pivoting base B233, and the first base B231 is connected to the side of the first base B232 that is away from the second pivoting base B233. Specifically, the second pivoting base B234, the second pivoting base B233, the second base B232, and the first base B231 are stacked in sequence along the left-right direction. The mounting base B230 is adapted to mate with the connecting base B190 and is locked to the connecting base B190 via a locking mechanism B240.In this embodiment, the mounting base B230, connecting base B190, and locking mechanism B240 can be found in the description of the first embodiment above and will not be repeated here. Referring to Figure 27 , each of the first bracket B21A and the second bracket B21B includes at least one engaging channel B250, each extending in the front-to-back direction. Each of the first bracket B21A and the second bracket B21B is provided with at least one locking member B261. Each locking member B261 moves in the left-right direction, possessing an engaged position extending into the corresponding engaging channel B250 and a non-engaged position retracted from the corresponding engaging channel B250. It will be appreciated that when the locking member B261 is in the engaged position, the carrier B300 is locked to the support assembly B200; when the locking member B261 is in the non-engaged position, the carrier B300 can be removed from the support assembly B200. The engaging channel B250 on the first bracket B21A can be referred to as the first engaging channel B25A, and the engaging channel B250 on the second bracket B21B can be referred to as the second engaging channel B25B. The locking member B261 provided on the first bracket B21A can be referred to as the first locking member B261A, and the locking member B261 provided on the second bracket B21B can be referred to as the second locking member B261B. In this embodiment, the number of the first engaging channels B25A and the number of the first locking members B261A can both be two, the locking and releasing directions of the two first locking members B261A are opposite, and the locking and releasing directions of the two second locking members B261B are opposite. Of course, in some alternative embodiments, the locking and releasing directions of the two first locking members B261A can be consistent, and the locking and releasing directions of the two second locking members B261B can be opposite or consistent. With reference to Figures 27 and 29 to 31, the bottom of the carrier B300 can be provided with, for example, two engaging rods B339. Each engaging rod B339 is used to engage with each engaging channel B250. When the carrier B300 is supported and locked by the support assembly B200, each engaging rod B339 is respectively engaged in the corresponding first engaging channel B25A and second engaging channel B25B. The carrier B300 is locked by the corresponding locking members B261. At this time, each locking member B261 extends into the corresponding locking channel B250, so that the carrier B300 can neither move relative to the support frame B210 in the left and right directions nor move out from the support frame B210.As each engaging rod B339 of the carrier B300 engages the corresponding engaging channel B250, it pushes the corresponding first locking member B261A and second locking member B261B toward the unengaged position. When each engaging rod B339 is fully engaged within the engaging channel B250, the corresponding first locking member B261A and second locking member B261B automatically pop out to the engaged position under the action of a reset member (not shown), thereby locking the engaging rod B339 within the engaging channel B250 and, in turn, locking the carrier B300 to the support assembly B200. In this embodiment, the locking member B261 can be unlocked (i.e., driven to move from the engaged position to the unengaged position) using any suitable release mechanism, which is not a limitation of this application. In the second embodiment, as shown in Figures 29 to 32 , a wheeled mobile device B1000 includes a frame B100, a carrier B300, and a support assembly B200. The wheeled mobile device B1000 in this embodiment differs from the wheeled mobile device B1000 in the second embodiment described above in at least the following ways. As shown in Figures 29 to 32 , two connecting blocks B190 are respectively provided on the left and right sides of the frame B100. The two connecting blocks B190 on the same side of the frame B100 include a first connecting block B190A and a first connecting block B190B, wherein the first connecting blocks B190A and the first connecting blocks B190B can be collectively referred to as connecting blocks B190. Each first connecting block B190A is, for example, fixedly mounted on a connecting portion B118 of the frame B100. Specifically, each first connecting block B190A is integrally formed on the connecting portion B118. Each second connecting base B190B is, for example, detachably mounted on the rear support rod B120 of the vehicle frame B100. The wheeled mobile device 1000 can be configured with two vehicles B300. The two vehicles B300 can be of the same type or different types. The two vehicles B300 can be mounted on the vehicle frame B100 in the same manner or in different manners.Optionally, as shown in FIG30 , two carriers B300 are mounted on the vehicle frame B100 via a support assembly B200. For details on how the carriers B300 are mounted on the vehicle frame B100 via the support assembly B200, reference may be made to the description in the second embodiment, which will not be repeated herein. Alternatively, as shown in FIG30 , one of the carriers B300 is mounted on a first connecting seat B190A located above the vehicle frame B100 via the support assembly B200, and the other carrier B300 is connected to the first connecting seat B190B located below the vehicle frame B100 via a suitable connecting structure. Alternatively, as shown in FIG31 , one of the carriers B300 is mounted on a second connecting seat B190B located below the vehicle frame B100 via the support assembly B200, and the other carrier B300 is connected to the first connecting seat B190A located above the vehicle frame B100 via a suitable connecting structure. In other words, the carrier B300 can be selectively mounted on the first connecting base B190A or the second connecting base B190B via the support assembly B200, or connected to the first connecting base B190A or the second connecting base B190B via a suitable connection structure. As shown in Figures 33 and 35 , in this embodiment, the structures of the first connecting base B190A and the first connecting base B190B are substantially identical. As shown in Figures 33, 34, and 36 to 38, the support assembly B200 includes a support frame B210, a mounting base B230, and a locking mechanism B240. The support frame B210 is a generally rectangular structure. Optionally, the support frame B210 is non-foldable. The support frame B210 includes a support housing B211 and a reinforcement member B219 disposed within the support housing B211. The reinforcement member B219 may include, for example, a U-shaped reinforcement bar. The support housing B211 includes an upper housing B211A and a lower housing B211B. A first engaging channel B25A is formed in the upper housing B211A, and a first locking member B261A is located in the accommodating cavity enclosed by the upper housing B211A and the lower housing B211B. A second engaging channel B25B is formed in the upper housing B211A, and a second locking member B261B is located in the accommodating cavity enclosed by the upper housing B211A and the lower housing B211B. The upper housing B211A forms a support plane B213. The support housing B211 is provided with an engaging channel B250 and a locking member B261. The locking member B261 can extend into the engaging channel B250 to lock the engaging rod B339 of the carrier B300 within the engaging channel B250. See Figures 34, 36, and 38. The mounting base B230 is integrally formed with the support housing B21L, but is not limited thereto. Specifically, the mounting base B230 is integrally formed with the upper housing B211A. The mounting base B230 is provided with a mounting groove B235.The mounting slot B235 is generally U-shaped, with the notch of the mounting slot B235 facing downward. The vehicle frame B100 is provided with a connecting seat B190, at least a portion of which can be inserted into the mounting slot B235 through the notch of the mounting slot B235. Referring to Figures 33 and 38 , the direction W2 of engagement of the mounting seat B230 with the connecting seat B190, which is 1 inch, is generally parallel to the vertical direction. The connecting seat B190 is fixedly or removably mounted on the vehicle frame B100. Optionally, the connecting seat B190 is provided with an abutment protrusion B191. When the connecting seat B190 is at least partially engaged in the mounting slot B235, the abutment protrusion B191 abuts against the slot door of the mounting slot B235. As shown in Figures 34, 37, and 38 , the locking mechanism B240 may include a locking member B241, a reset member B243, and a release member B242. The locking member B241 is movably disposed on the mounting base B230. Specifically, the locking member B241 is movable relative to the mounting base B230 in a first direction D1. When the mounting base B230 is engaged with the connecting base B190, the engagement direction W2 is non-parallel to the first direction D1. The mounting base B230 is provided with an exit passage B239, through which the locking member B241 is inserted, thereby restricting the movement of the locking member B241 in the first direction D1. Referring also to Figures 37 and 38, a release member B242 is movably disposed on the mounting base B230. Upon being operated, the release member B242 is movable relative to the mounting base B230 in a second direction D2, which is substantially parallel to the front-to-back direction. One of the release member B242 and the locking member B241 is provided with a driving pin B2419, and the other of the release member B242 and the locking member B241 is provided with a driving bevel B2421. The driving pin B2419 extends through the driving bevel B2421 and is movable along the extension direction of the driving bevel B2421. In this embodiment, the driving pin B2419 extends through the locking member B241 and is detachable. The driving bevel B2421 is provided on the release member B242. Of course, the driving pin B2419 may also be fixedly provided on the locking member B241. In an alternative embodiment, the driving pin B2419 may be fixedly or detachably provided on the release member B242, while the driving bevel B2421 is provided on the locking member B241. In this way, when the release member B242 is operated along the second direction D2, the driving pin B2419 is driven to move along the driving inclined slot B2421, thereby driving the locking member B241 to move along the first direction D1.Conversely, when the locking member B241 moves in the first direction D1, it drives the driving pin B2419 along the driving slant slot B2421, thereby driving the release member B242 in the second direction D2. The extension direction of the driving slant slot B2421 is not aligned with either the first direction D1 or the second direction D2, and the first direction D1 is not aligned with the second direction D2. Specifically, the first direction D1 is substantially parallel to the left-right direction, and the first direction D2 is substantially parallel to the front-back direction. A reset member B243 is disposed between the locking member B241 and the release member B242. The reset member B243 constantly moves the release member B242 toward its initial position, thereby driving the locking member B241 toward its locked position via the release member B242. The release member B242 is provided with a receiving groove B2422. The driving inclined groove B2421 is provided on the sidewall of the receiving groove B2422 and communicates with the receiving groove B2422. The locking member B241 is at least partially received within the receiving groove B2422. One end of the reset member B243 abuts the locking member B241, while the other end abuts the bottom of the receiving groove B2422. This prevents the reset member B243 from shifting during elastic energy storage. The wheeled mobile device B1000 and its support assembly B200 provided in accordance with embodiments of the present invention have at least the following beneficial effects: By providing a connecting groove B235 and a locking pin B220 adapted for plugging into the anchor assembly B330 of the vehicle B300, the user can quickly install or remove the vehicle B300 from the vehicle frame B100 as needed. This not only facilitates user use but also increases the usage modes of the vehicle B300, enhancing the versatility of the vehicle B300. Furthermore, the support assembly B200 can be adapted to different types of vehicles B300 (e.g., safety seats, animal travel crates, baby sleeping boxes, or stroller seats). By changing the type of vehicle B300, different user needs can be met, thereby enhancing the versatility of the wheeled mobile device B1000. Figures 39 and 41 illustrate a vehicle C1000 (or a wheeled mobile device in other embodiments) according to an embodiment of the present invention. The vehicle C1000 may include a vehicle body C100 (or a frame in other embodiments) and a storage device C200 according to an embodiment of the present invention. The vehicle C1000 may include, but is not limited to, a stroller. The present invention briefly describes the structures of the vehicle body C100 and the storage device C200, taking the stroller as an example.In one embodiment, when the carrier C1000 is a stroller, the carrier body C100 serves as the frame. The overall structure of the frame is generally bilaterally symmetrical and may include a handlebar C110, a front wheel frame C120, and a rear wheel frame C130. It should be noted that the stroller can be used as a child stroller, a pet stroller, a shopping cart, or the like. For example, when the carrier body C100 (or the frame) is provided with a seat or a carrycot, the stroller can be used as a child stroller. When the carrier body C100 (or the frame) is provided with a pet carrier, the stroller can be used as a pet stroller. When the carrier body C100 (or the frame) is provided with a shopping basket, the stroller can be used as a shopping cart. Continuing with Figures 39 and 41 , in one embodiment, the front wheel frame C120 and the rear wheel frame C130 can be fixedly connected via a connecting base C140. Similarly, the handrail C110 can also be fixedly connected to both the front wheel frame C120 and the rear wheel frame C130 via a connecting base C140. The front wheel frame C120 and the rear wheel frame C130 are disposed at an angle, and the handrail C110 is disposed at an angle to both the front wheel frame C120 and the rear wheel frame C130. Of course, in another alternative embodiment, the front wheel frame C120 and the rear wheel frame C130 can be pivotally connected via the connecting base C140. Similarly, the handrail C110 can also be pivotally connected to the connecting base C140. This allows the vehicle body C100 to switch between an expanded and collapsed state. Referring again to Figures 39 and 41 , in one embodiment, both the front wheel frame C120 and the rear wheel frame C130 are generally U-shaped. The front wheel frame C120 may include left and right front rods C121 and a front crossbar C122 connected between the two front rods C121. The front crossbar C122 extends generally along a first direction F1, which corresponds to the left-right direction. When the vehicle C1000 is used as a child stroller, the front crossbar C122 can also serve as a footrest. Similarly, the rear wheel frame C130 may include left and right rear rods C131 and a rear crossbar C132 connected between the two rear rods C131. The rear crossbar C132 extends along the first direction F1. Specifically, the upper ends of the two rear rods C131 are connected to the upper ends of the front rod C121 on the same side via corresponding connecting sockets C140. Of course, in another alternative embodiment, the front wheel frame C120 and / or the rear wheel frame C130 may also have other embodiments. For example, the front wheel frame 120 only includes two front rods C121, and the two front rods C121 are arranged parallel to each other or the two ends of the two front rods C121 are connected to form a V-shaped structure.Alternatively, the rear wheel frame C130 includes only two rear rods C131, which are arranged in parallel or connected at one end, forming a V-shaped structure. It should be noted that, unless otherwise specified or limited, directional terms such as "left" and "right" with respect to the vehicle C1000 in various embodiments of the present invention are based on the "left" and "right" orientations of the vehicle C1000 during normal travel. Arrows L and R in the figures schematically indicate the "left" and "right" directions. These directional terms are intended solely to clarify the description of the embodiments of the present invention and are not intended to unduly limit the scope of protection of the present invention. Referring to Figures 39 and 41 , in one embodiment, the handrail C110 includes a push handle C111 and a grab handle C112. There are two push handles C111, and a handrail C112 is connected between the two push handles 111. The handrail C112 is used for a user to hold to push the vehicle C1000. oThe lower ends of the two push handles C111 are, for example, respectively connected to the connecting base C140 on the same side. It should be noted that the push handles C111 in this embodiment can be a telescopic rod structure, or alternatively, a folding rod structure or a non-bendable straight rod structure. When a user uses the aforementioned carrier C1000 as a pet stroller, they typically need to carry a variety of items. These items include, but are not limited to, drinking cups for water, paper towels (such as rolls or tissues), and garbage bags for collecting pet waste. To improve the portability of various items, referring to Figures 39 to 42, an embodiment of the present invention provides a storage device C200 suitable for installation within the carrier body C100 to facilitate storage of various items. Figures 40 and 42 illustrate a storage device C200 according to an embodiment of the present invention, comprising a first storage rack C210. ​​Specifically, as shown in Figures 39 to 42, the first storage rack C210 is connected to the handlebar C110 of the vehicle body C100. More specifically, the first storage rack C210 is connected to one of the handlebars C111 of the handlebar C110. Specifically, the first storage rack C210 includes a first storage compartment C211 (see Figure 44) and a cover C212. The first storage compartment C211 is hollow and is used to store an object C300 to be retrieved. The first storage compartment C211 is provided with a first opening C2111 and a second opening C2112 (see Figure 44). The cover C212 is movably positioned at the first opening C2111, allowing the cover C212 to have a first position (see Figure 40) and a second position (see Figure 42). When the cover C212 is in the first use position, it covers the first opening C2111. When the cover C212 is in the second use position, the first opening C2111 is exposed, allowing the user to insert the object C300. The second opening C2112 allows a portion of the edge of the object C300 to extend (see Figures 43 and 44), making it easier for the user to pull it. It should be noted that the object C300 can be a garbage bag roll C301. The garbage bag roll C301 refers to a roll of continuous, pre-cut garbage bags. To use the garbage bag, the user simply pulls the end of the garbage bag and tears off a piece of garbage bag along the pre-cut dividing line. Of course, in other embodiments, the object C300 can also be a tissue roll or a tissue box containing tissues. In this way, the end or portion of the edge of the tissue can extend through the second opening C2112, allowing the user to pull the tissue directly through the second opening C2112. The following briefly describes the operation effect of the partial structure of the storage device C200 by taking the object C300 to be taken as a garbage bag roll C301 as an example.In the aforementioned storage device C200, the first storage element C211 is hollow and features a first opening C2111. This allows a user to store a roll of garbage bags C301 within the first storage element C211 through the first opening C2111. Furthermore, the first storage element C211 also features a first opening C2112, which allows one end of the roll of garbage bags C301 to extend, allowing the user to easily remove the bag from the second opening C2112 when needed. Furthermore, because the cover C212 is movably positioned at the first opening C2111, it can be switched between a first and second position. When in the first position, the cover C212 covers the first door C2111. Therefore, after the garbage bag roll 301 is stored in the first storage object C211, the cover C212 can be maintained in the first use position. Thus, when the user pulls the garbage bag downward through the second opening C2112 at any time, the cover C212 can effectively prevent the garbage bag roll C301 from flying due to uneven pulling force, thereby preventing the garbage bag roll C301 from falling off the second storage object C211. In summary, the design of the storage device C200 fully considers the convenience of storing and retrieving the garbage bag roll C301, while also ensuring the stability of the garbage bag roll C301 during use, preventing the garbage bag roll C301 from falling due to improper operation, and improving the ease of use of the carrier C100. It should be noted that when the object C300 to be removed is a tissue roll or a tissue box containing tissues, the end or partial edge of the tissue can similarly extend out of the first storage object C211 through the second opening C2112. Therefore, when a tissue is needed, the user can simply withdraw the tissue through the second opening C2112. Referring to Figures 40 and 42, in one embodiment, the cover C212 has a pivotal connection C2121, which pivots the cover C212 to the first rack C210, allowing the cover C212 to switch between a first and second use position. Of course, in another alternative embodiment, the cover C212 can be slidably mounted on the first rack C210, thereby also enabling the cover C212 to switch between the first and second use positions. 40 and 42 , in one embodiment, a first engaging portion is defined on a sidewall of the first storage object C211, and a second engaging portion C2122 is defined on the cover C212. Specifically, when the cover C212 pivots to the first use position, the second engaging portion C2122 engages with the first engaging portion to prevent the cover C212 from switching to the second use position.This allows the cover C212 to be stably positioned over the first opening C2111. More specifically, the second engaging portion C2122 and the pivoting portion C2121 are arranged opposite each other along the circumferential direction of the cover C212. This improves the stability and reliability of the locked cover C212. In one embodiment, one of the first engaging portion and the second engaging portion C2122 is a resilient arm C2122a, and the other is a bayonet. The resilient arm C2122a is provided with a limiting protrusion C2123, which engages with the bayonet. Specifically, as shown in Figures 42 and 44, in this embodiment, the first engaging portion C2122 is a latch, and the second engaging portion C2122 is a resilient arm C2122a. The resilient arm C2122a has an operating end C21221 and a locking end C21222. The limiting protrusion C2123 is located at the locking end C21222. When the first cover C212 is in the first use position, the locking end C21222 extends into the first opening C2111 and engages with the latch. The operating end C21221 at least partially protrudes from the first opening C2111, allowing a user to operate (e.g., press) the operating end C21221 to disengage the locking end C21222 from the latch. It should be noted that the aforementioned "hook" can be a slot structure directly provided on the side wall of the first storage object C211. Alternatively, the "hook" can be the mouth of a hook provided on the side wall of the first storage object C211, with the hook body inverted so that the opening of the hook mouth faces vertically downward. Referring to Figures 40 and 42, in one embodiment, an operating member C213 is provided on the side of the cover C212 facing away from the first opening C2111. When the cover C212 is in the first use position, the operating member C213 protrudes from the surface of the cover C212. This facilitates the user to flip the cover C212 using the operating member C213. Specifically, the operating member C213 is provided protruding from the edge of the cover C212 and is disposed opposite the pivotal portion C2121. The operating member C213 can have a columnar, cubic, or pyramidal structure. Specifically, in this embodiment, as shown in Figures 40 and 42, the operating member C213 is a 1 / 2 vertebral structure, and the bottom wall of the vertebral structure is flush with the edge of the cover body C212. The bottom wall of the vertebral structure is called the operating side wall C2131 of the operating member C213. The operating side wall C2131 is provided with a notch C3132, and the arched single-sex arm C2122a is provided at the notch C3132.Specifically, the side wall of the first placement object C211 with the latch is referred to as the mating wall. When the cover C212 is in the first use position, the operating side wall C2131 is disposed opposite the mating wall, and the operating side wall C2131 at least partially protrudes from the first opening C2111. When the cover C212 is switched from the first use position to the second use position, the user can directly flip the cover C212 so that the cover C212 covers the first opening C2111. During the covering process, the limiting protrusion C2123 located at the locking end C21222 of the elastic arm C2122a first abuts against the mating wall, causing the elastic arm C2122a to deform and tend to move away from the mating wall. When the limiting protrusion C2123 aligns with the latch, the elastic arm C2122a returns to its original position, locking the limiting protrusion C2123 with the latch, and trapping the locking end C21222 of the elastic arm C2122a within the first object C211. To extend the service life of the elastic arm C2122a and reduce insertion resistance of the limiting protrusion C2123, a guiding slope C21231 is provided on the limiting protrusion C2123. To switch the cover C212 from the first to the second position, the user first presses the exposed operating end C21221 of the elastic arm C2122a, causing it to move the locking end C21222 away from the mating wall and disengage the limiting protrusion C2123. The user then grasps the operating member C213, which allows the cover C212 to flip back to the first position. Referring to Figures 42 and 44 , in one embodiment, the first opening C2111 and the first opening C2112 are disposed opposite each other, with the first opening C2112 facing the ground. Specifically, the second opening C2112 is located at the bottom of the first storage unit C211. Of course, in another embodiment, the second opening C2112 may also be located on the sidewall of the first storage unit C211. Referring to Figures 40 and 42 , in one embodiment, the first storage rack C210 also includes a second storage unit C214. Similarly, the second storage unit C214 is hollow and has a third opening C2141. The second storage unit C214 can be used to store various items, such as mobile phones and disinfectant, depending on user needs. Optionally, the shape of the first storage unit C214 is not particularly limited; for example, it can be a cubic structure, or a round columnar structure. Specifically, in this embodiment, the second storage unit C214 is a flat cubic structure, primarily used to store mobile phones.More specifically, a first stopper C215 is provided on the edge of the second opening C2141. The first stopper C215 extends circumferentially around the third door C2141. The first stopper C215 defines a first through-hole C2151 that communicates with the third door C2141. The inner wall of the first through-hole C2151 is generally concave-convex. Specifically, the first stopper C215 may be made of plastic (e.g., TPE, rubber, or silicone), but is not limited to this. When an item such as a mobile phone is placed in the second storage C214, the first stopper C215 contacts the outer surface of the mobile phone, thereby increasing the friction coefficient between the mobile phone and the mobile phone, effectively preventing the mobile phone from accidentally falling out of the first storage C214. Furthermore, the first limiting block C215 is made of a flexible plastic piece. It prevents a mobile phone from directly colliding with the edge of the third opening C2141 during movement of the carrier body C100, thereby reducing potential damage to the mobile phone. It should be noted that the first storage rack C210 may be provided with at least one second storage object C214. When multiple second storage objects C214 are provided, the shapes of the second storage objects C214 may be the same or different. Referring to Figures 39, 41, and 43, in one embodiment, the storage device C200 further includes a first storage rack C220. The first storage rack C220 is configured to interface with the carrier body C100. Specifically, the second storage rack C220 is connected to the rider frame C110. The second storage rack C220 includes a second storage object C221, which is hollow and has a fourth opening C2211. The second storage C214 can be used to store various items, such as cups, mobile phones, disinfectant, and other items, depending on user needs. Similarly, the shape of the second storage C221 is not specifically limited; for example, it can be a cube; or, alternatively, a round, cylindrical structure. Specifically, in this embodiment, the second storage C221 is cylindrical and primarily used to store cups or beverage bottles. More specifically, a first stopper C222 is provided at the edge of the fourth opening C2211. The first stopper C222 extends circumferentially around the fourth opening C2211 and defines a second through-hole C2221 communicating with the fourth opening C2211. The inner wall of the second through-hole C2221 is generally concave-convex. Specifically, the second stopper C222 can be made of plastic (e.g., TPE, rubber, or silicone), but is not limited thereto.When placing items such as a cup or bottle on the third storage object C221, the second stopper C222 contacts the outer wall of the cup or bottle, increasing the friction coefficient between the cup or bottle and the third storage object C221, effectively preventing the cup or bottle from accidentally falling out of the third storage object C221. Furthermore, the first stopper C222 also mitigates the impact force between the cup or bottle and the edge of the fourth opening C2211. It should be noted that the first storage rack C220 can be equipped with at least one third storage object C221. When multiple third storage objects C221 are provided, the shapes of the second storage objects C221 can be the same or different. In one embodiment, the first storage rack C210 and the second storage rack C220 can be mounted on two push rods C111, respectively. This helps maintain the balance of the carrier body C100. Of course, in another alternative embodiment, the first rack C210 and the second rack C220 can be simultaneously connected to the same push rod C111 of the push rack, which is equivalent to the first rack C210 and the second rack C220 being simultaneously installed on the left or right push rod C111. The first rack C210 and the second rack C220 can be fixedly connected to the push rod C111. Of course, both can also be installed on the push rod C111 through a detachable connection method, such as a snap connection or adhesive connection. Specifically, in this embodiment, as shown in Figure 44, the push rod C111 is provided with a special-shaped card slot C113, and the first rack C210 and the second rack C220 are each provided with a K-connection portion C216. The first rack C210 and the first rack C220 are K-connected to the corresponding special-shaped R-shaped slot C113 on the push rod C111 via the K-connection portion C216 provided thereon. Referring to Figures 39, 41, 43, and 45, in this embodiment, the first rack C210 and the second rack C220 are respectively connected to two push handles C111. In one embodiment, the storage device C200 further includes a support member C230 connected between the first rack C210 and the second rack C220. This increases the number of support points for the first rack C210 and the second rack C220, thereby improving the stability of the first rack C210 and the second rack C220 after installation. Furthermore, the support member C230 can be used to hang relatively lightweight items, such as towels, ropes, and garbage bags. Optionally, the support member C230 can be made of plastic or metal, without specific limitation.The technical features of the above-described embodiments may be combined in any manner. For the sake of brevity, not all possible combinations of each technical feature in the above-described embodiments are described. However, as long as no conflicts exist between these combinations of technical features, they should be considered within the scope of this specification. The above-described embodiments merely represent a few implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art may make various variations and improvements without departing from the spirit of the present invention, and these variations and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims. This application provides a transportation system D1000 that can easily accommodate a pet carrier D200 on a stroller. A detailed description of one or more embodiments of the disclosed system is presented herein by way of example and not limitation in conjunction with the accompanying drawings. Referring to Figures 46 to 50 , one embodiment of a transportation system D1000 for carrying a pet carrier D200 is illustrated. Referring to Figure 46 , an embodiment of a transportation system D1000 is illustrated. As shown, a transportation system D1000 includes a pet carrier D200 and a cart D100. Cart D100 has a frame D100a, which includes a handle D110, a pair of rear legs D130, and a pair of front legs D120. Handle D110 has two handles: a left handle D110a and a right handle D110b. Front legs D120 are located below handle D110 and are substantially flush with the handle D110. The handle D110, front legs D120, and rear legs D130 are pivotally connected, allowing the frame D100a to be expanded or collapsed. This invention describes a load-bearing member D140 installed between a left handle D110a and a right handle D110b. Load-bearing member D140 includes a support member D141 (also called a support base), a first connecting portion D142 (also called a sliding base in this embodiment) on each side, and a second connecting portion D143 (also called a connecting base in this embodiment). The support member D141 supports the pet carrier D200, and the second connecting portion D143 connects to the first connecting portion D142. The support member D141 is also connected to the first connecting portion D142. In this embodiment, the handle D110 includes a handlebar D1111 and a sleeve rod D1112 located outside the handlebar D1111.As shown in FIG46 , a pet carrier D200 includes a pair of anchors D210 that can be inserted into LATCH or ISOFIX systems in vehicles or aircraft. Furthermore, according to a non-limiting embodiment of the present disclosure, a stroller D100 can include a first connector D143 of the present disclosure, with the first connector D143 having a connecting slot D1431 (or pocket) that similarly receives or accepts the anchors D210 of the pet carrier D200. In the illustrated non-limiting embodiment, the load-bearing member D140 also includes a locking device D144 provided on the first connector D142. The locking device D144 can be locked or unlocked with the vehicle frame D100a, allowing the load-bearing member D140 to be adjusted in height by moving the first connector D142 along the vehicle frame D100a to a desired position. More specifically, the first connecting portion D142 is connected to the first rod Dili of the vehicle frame DIOOa, and the first connecting portion D142 moves along the first rod Dili. In the illustrated non-limiting embodiment, the sleeve rod D1112 serves as the first rod Dili of the vehicle frame DIOOa, and the first connecting portion D142 is connected to the sleeve rod D1112, and the second connecting portion D142 moves along the sleeve rod D1112. In some embodiments not shown, the handlebar D110 is not provided with the sleeve rod D1112, but only with the handlebar rod D1111. The handlebar rod D1111 serves as the first rod Dili of the vehicle frame DIOOa, and the first connecting portion D142 is connected to the handlebar rod D1111, so that the bearing member D140 can move along the handlebar rod D1111. In some embodiments (not shown), the front leg rod D120 or the rear leg rod D130 serves as the first rod Di11 of the vehicle frame DI00a, the first connecting portion D142 is connected to the front leg rod D120 or the rear leg rod D130, and the load-bearing member D140 is movable along the front leg rod D120 or the rear leg rod D130. In one embodiment, the first leg Di11 has a plurality of holes D11121, which are configured to receive the locking device D144 when the first connecting portion D142 moves along the first leg Di11. More specifically, the plurality of holes D11121 are configured to receive the actuating portion D1441 of the locking device D144 by causing the actuating portion D1441 of the locking device D144 to pivot along an axis. In an exemplary or representative embodiment, the actuating portion D1441 includes a protrusion D14411, which can be received in the plurality of holes D11121 of the first rod body Dill to lock the locking member with the vehicle frame D100a.Specifically, the actuator D1441 includes a finger-shaped portion D14412 and a protrusion D14411. The finger-shaped portion D14412 and the protrusion D14411 are located on opposite sides of the actuator D1441. The protrusion D14411 faces inwardly of the first rod Dill, while the finger-shaped portion D14412 faces outwardly of the first rod Dill. The elastic member D1442 can be positioned between the actuator D1441 and the vehicle frame D100a by pivoting along an axis. The connecting groove D1431 of the second connecting portion D143 is similar to the connecting groove B212 in the above-described embodiment. The second connecting portion D143 also has a locking member D1432 (e.g., a locking pin) located within the connecting groove D1431. The locking member D1432 is used to connect to the anchor D210 of the pet carrier D200. Details thereof will not be repeated here. In one embodiment, the locking device D144 further includes a first actuator D1441a on a first side of the first connecting portion D142 and a second actuator D1441b on a second side of the first connecting portion D142. Each of the first and second actuators D1441a and D1441b further includes a finger D14412 and a protrusion D1441E located on opposite sides. The locking member further includes an elastic member D1442 located between the first and second actuators D1441a and D1441b. The elastic member D1442 is located from the vehicle frame D100a and is connected to each of the first and second actuators D1441a and D1441b. The first actuator D1441a is pivotally movable along a first axis, and the first actuating portion D1441h is pivotally movable along a second axis. The protrusion D14411 is receivable in the plurality of holes D11121 on the first lever Di1i. Specifically, the protrusions of the first actuator D1441a and the protrusions of the second actuating portion D1441b are respectively receivable in the plurality of holes D11121 on the first lever Di1i, thereby locking the locking member with the vehicle frame D100a. In some embodiments, the support member D141 of the load-bearing member D140 is detachable. Figure 51 is a schematic diagram illustrating an isometric view of an exemplary or representative embodiment of the transport system D1000. Figure 52 is an enlarged exploded view of an exemplary or representative embodiment of the transport system D1000. In some embodiments, as shown in Figures 51 to 54, the first connection portion D142 may not be connected to the second connection portion D143 on two opposite sides at the same time, but may be connected to the second connection portion D143 on one side, thereby allowing the first connection portion D142 to move independently along the first rod body Dili without being disturbed by the movement of the first connection portion D142 on the other side.The first connecting portion D142 and the second connecting portion D143 of the support member D140 are detachably connected. Specifically, the first connecting portion D142 further includes a first sliding base D142a and a second sliding base D142b, while the second connecting portion D143 further includes a first connecting base D143a and a first connecting base D143b. The first sliding base D142a and the first sliding base D142b are connected to the first connecting base D143a and the first connecting base D143b, respectively. The first sliding base D142a and the first sliding base D142b move independently along the vehicle frame D100a. In some embodiments, the support member D141 is not connected to both second connecting portions D143 simultaneously; instead, the two support members D141 are connected to the two second connecting portions D143 separately. More specifically, the support member D141 extends from one side of the second connecting portion D143 to support the pet carrier D200. In another representative embodiment of a load-bearing member D140 of a transport system D1000, as shown in Figures 53 and 54 , a first connecting portion D142 and a second connecting portion D143 can be connected via a block in a male-female connection, but this is not limited to the embodiments described herein. The second connecting portion D142 is provided with a connector D1421, which in this embodiment protrudes inward (i.e., toward the inside of the cart D100). The second connecting portion D143 is provided with a mounting slot D1433 (also known as a pocket), into which the connector D1421 can be inserted and removed. When the mounting groove D1433 of the first connecting portion D143 engages with the connector D1421 of the first connecting portion D142, the first connecting portion D143 is attached to the cart D100. The anchor D210 of the pet carrier D200 connects to the engaging member D1432 within the connecting groove D1431 of the first connecting portion D143, thereby attaching the pet carrier D200 to the cart D100. In some non-limiting embodiments, the positions of the connector D1421 and the mounting groove D1433 are interchangeable, with the connector D1421 located on the second connecting portion D143 and the mounting groove D1433 located on the first connecting portion D142. See Figures 55 to 62 for another representative embodiment of the load-bearing member D140. 56 to 59, the bearing member D140 includes a support member D141 and a connecting portion D145, the support member D141 and the connecting portion D145 are movably connected, the support member D141 can be switched between a use position and a storage position, and the connecting portion D145 is connected to the vehicle frame D100a.When the support member D141 is in the use position, the support member D141 is used to support the pet carrier D200. Referring to Figure 56, in this embodiment, the support member D141 is a pivotable support frame that can pivot relative to the connection portion D145. When the support member D141 (i.e., the pivotable support frame) is in the storage position, the support member D141 (i.e., the pivotable support frame) can be stored in the groove D11122 provided on the first rod Dill. A caregiver can place the pet carrier D200 on the pivotable support frame when traveling. It should be noted that the first rod Dill TJ in this embodiment is the handle bar of the handle DUO. In other embodiments, the first rod D111nT is the sleeve rod D1112 of the handle D110, the front leg rod D120, or the rear leg rod D130. In the exemplary embodiment shown, a stopper D146 (or locking device) is provided on the connecting portion D145. The stopper D146 is disposed on the connecting portion D145 and can be switched between a closed position and an open position. When the stopper D146 is in the closed position, as shown in Figures 55 and 56, the stopper D146 is used to hold the support member D141 (i.e., the pivotable support frame) stationary. When the stopper D146 is in the open position, as shown in Figures 57 and 58, the stopper D146 releases the lock, allowing the support member D141 (i.e., the pivotable support frame) to move. Furthermore, referring to Figures 55 to 59, the connecting portion D145 and the support member D141 are rotatably connected. The support member D141 has an in-use position and a stowed position. The support member D141 has two side rods D1411 and a connecting rod D1412 connecting the two side rods D1411. The ends of the two side rods D1411 are pivotally connected to the connecting portions D145. The ends of the two side rods D1411 are pivotally connected to the two connecting portions D145. When the support member D141 is in the in-use position (as shown in FIG. 55 ), the support member D141 supports the pet carrier D200, which can be placed on the support member D141. When the support member D141 is in the stowed position (as shown in FIG. 59 ), the support member D141 is stored in the groove D11122 of the first rod body D111. When the support member D141 is in the use position, it is generally horizontal. When the support member D141 is in the storage position, its two side bars D1411 extend along the left and right handles D110a and D110b of the stroller D100, respectively, and are positioned within the groove D11122 of the first rod Dill. Referring to the embodiments shown in Figures 55, 56, and 59, the groove D11122 extends along the length of the first rod Dill (the handle bar D1111 in this embodiment), and the connecting portion D145 is located on the handle D110, near the upper end of the groove D11122. When the support member D141 is in the use position, the pet carrier D200 is relatively close to and above the handle D110. When the support member D141 switches from the use position to the storage position, the support member D141 rotates downward relative to the connection portion D145 until the side rod D1411 is located in the groove D11122 of the first rod body Di 11 (position 2K as shown in FIG. 59 ).Referring to the embodiment shown in Figures 60 to 62 , the groove D11122 extends along the length of the first rod Dili, and the connecting portion D145 is located at the lower end of the handlebar D110, near the groove D11122. When the support member D141 is in the use position, the pet carrier D200 is relatively close to the lower side of the handlebar D110. When the support member D141 switches from the use position to the storage position, the support member D141 rotates upward relative to the connecting portion D145 until the side rod D1411 is located within the groove D11122 of the first rod Dili (as shown in Figure 62 ). It should be noted that the connecting portion D145 can slide along the first rod Dili by engaging the actuating portion D1441 with the multiple holes D11121 of the sleeve rod D1112, as in the embodiment shown in Figure 47 . In this case, the connecting portion D145 can also be referred to as a sliding base. Alternatively, the connection portion D145 may be positioned only in at least one of the higher position shown in FIG. 55 and the lower position shown in FIG. 60 , which is not limited here. More specifically, the connection portion D145 includes a base body D145L and a stopper D146 movably connected to the base body D145L. The stopper D146 is movable relative to the base body D145L between a closed position and an open position. When the stopper D146 is in the closed position, it restricts movement of the support member D141 between the in-use position and the stowed position. Specifically, when the stopper D146 is in the closed position, the stopper D146 is located within the movement path of the support member D141 between the in-use position and the stowed position, maintaining the support member D141 in either the in-use position or the stowed position. When the stopper D146 is in the open position, the stopper D146 allows movement of the support member D141 between the in-use position and the stowed position. Specifically, when the stopper D146 is in the open position, it moves out of the motion path of the support member D141 between the in-use and storage positions, allowing the support member D141 to switch between the open and closed positions. More specifically, the stopper D146 is pivotally connected to the base body D1451.
