The portable carrier 1000 in Figure 1 is equipped with a buffer body 1510, while the portable carrier 1000 in Figure 2 is also equipped with a buffer body 1510. The portable carrier 1000 has a carrying space for accommodating an animal. The portable carrier 1000 can be carried on the person (e.g., carried in the hand or slung across the back) and can be secured to a seat in a vehicle such as a train or car. The portable vehicle 1000 includes a vehicle body 1100 and a base 1200. The vehicle body 1100 is positioned adjacent to the base 1200, and the vehicle body 1100 and the base 1200 together form a carrying space. The base 1200 is made, for example, of a rigid material to support the vehicle body 1100. The vehicle body 1100 may include a fabric sheet or other material that encloses the carrying space. The portable vehicle 1000 is also equipped with a reinforcement 1300. The reinforcement 1300 is connected to the base 1200 and extends to the sides of the vehicle body 1100 to support the vehicle body 1100, thereby limiting deformation of the vehicle body 1100 under impact.The reinforcement 1300 can provide an anti-collision function; therefore, the "reinforcement" in the second embodiment can also be referred to as an "anti-collision member." As shown in Figures 1 and 2, the carrier body 1100 includes a front portion 1140, a left side portion 1120, a right side portion 1130, and a rear portion 1160. The front portion 1140 forms the front wall of the load-bearing space, the left side portion 1120 forms the left wall of the load-bearing space, the right side portion 1130 forms the right wall of the load-bearing space, and the rear portion 1160 forms the rear wall of the load-bearing space. In some embodiments, the bottom wall of the load-bearing space is formed by the base 1200, and the front portion 1140, left side portion 1120, right side portion 1130, and rear portion 1160 are directly connected to the base 1200. In some alternative embodiments, the carrier body 1100 includes a bottom portion that is fixed to the base 1200 and forms the bottom wall of the load-bearing space. The reinforcement member 1300 is connected to the base 1200 and extends through the bottom of the carrier body 1100. As shown in Figures 1 and 2, the portable carrier 1000 is equipped with a handle 1180. The portable carrier 1000 is provided with a top 1170, which forms the top wall of the carrying space. The handle 1180 is provided on the top 1170 of the carrier body 1100, and the portable carrier 1000 can be conveniently carried by the handle 1180. To facilitate carrying, the portable carrier 1000 is also provided with two (but not limited to two) buckles 1190, which are used for detachable connection with a crossbody strap. The two buckles 1190 are respectively provided on two opposite sides of the carrier body 1100, such as the front side 1140 and the rear side 1160. The two buckles 1190 are distributed along the diagonal line of the carrier body 1100. As shown in Figures 3 to 5, the base 1200 includes a first cover 1210 and a second cover 1220, which are detachably connected via fasteners 1250. Fasteners 1250 may be, for example, screws or bolts. Alternatively, the first cover 1210 and the second cover 1220 may be detachably connected, for example, by a snap-fit ​​connection. Referring to Figure 5, in an embodiment, the first cover 1210 and the second cover 1220 together form a receiving space 1230. A portion of the reinforcement 1300 extends into the receiving space 1230 and connects to the base 1200. This ensures a smoother bottom wall of the receiving space, preventing the reinforcement 1300 from interfering with objects carried within the receiving space, thereby improving the comfort of the receiving space. In some alternative embodiments, the receiving space 1230 is a recessed groove recessed into the front side of the base 1200.In other alternative embodiments, the accommodation space 1230 is a groove recessed into the upper surface of the base 1200. The portion of the reinforcement member 1300 extending into the accommodation space 1230 can be completely contained within the accommodation space 1230 without protruding from the upper surface of the base 1200, thereby preventing the reinforcement member 1300 from interfering with objects carried in the load space and improving the comfort of the load space.

The portion of the reinforcement member 1300 extending into the accommodation space 1230 can be completely contained within the accommodation space 1230 without protruding from the lower surface of the base 1200, thereby allowing the base 1200 to be placed more stably on a vehicle seat or the ground. In these alternative embodiments, the base 1200 can have a single-layer structure or a multi-layer structure, which is not limited by the present invention. As shown in Figures 5 and 7, in one embodiment, a portable vehicle 1000 is provided with an anchor assembly 1400 adapted to connect to a vehicle seat to secure the portable vehicle 1000 thereto. The anchor assembly 1400 includes at least one connection assembly 1410, configured to connect to at least one connection point on a vehicle seat. Specifically, the connection assembly 1410 is adapted to connect to an ISOFIX interface. In this context, the "connection assembly" may also be referred to as an "ISOFIX connector." The at least one connection assembly 1410 is movably connected to the base 1200 to enable switching between a deployed position (also referred to as a use position) and a collapsed position. The base 1200 is provided with at least one collapse space 1260. When the at least one connection assembly 1410 is in the collapsed position (i.e., when the anchor assembly 1400 is collapsed), the at least one connection assembly 1410 is accommodated within the at least one collapse space 1260. When at least one connecting assembly 1410 is in the deployed position (i.e., when the anchor assembly 1400 is in the deployed state (also referred to as the in-use state)), the at least one connecting assembly 1410 can extend out of at least one stowed space 1260 to connect with at least one connection point on a vehicle seat. Referring to Figures 5 and 7 , at least one connecting assembly 1410 is pivotally connected to the rear portion of the base 1200, and the at least one stowed space 1260 is disposed at the rear portion of the base 1200. The reinforcement member 1300 is connected to the front portion of the base 1200, and the portion of the base 1200 distal from the reinforcement member 1300 is defined as the rear portion of the base 1200.The front portion of the base 1200 forms the front side of the base 1200. The front side of the base 1200 forms a continuous transition with the outer side of the front side 1140 of the vehicle body 1100, which is equivalent to the front side of the base 1200 being at least partially flush with the outer side of the front side 1140. The rear portion of the base 1200 forms the rear side of the base 1200. The rear side of the base 1200 forms a continuous transition with the outer side of the rear side 1160 of the vehicle body 1100, which is equivalent to the rear side of the base 1200 being at least partially flush with the outer side of the rear side 1160. In this embodiment, there are two connecting assemblies 1410, each pivotally connected to the rear side of the base 1200. There are two folding spaces 1260, which are spaced apart in the left-right direction. In this embodiment, the folding spaces 1260 are grooves recessed into the rear side of the base 1200. When the two connecting assemblies 1410 are in the folded position, they are stored in corresponding folding spaces 1260. For example, the outer side of the folded connecting assembly 1410 is flush with the outer side of the base 1200. In other embodiments, the anchor assembly 1400 may include more than two connecting assemblies 1410, and the number of folding spaces 1260 may also be two or more. The two or more connecting assemblies 1410 may be connected to two or more connection points on the vehicle seat. As shown in Figures 5 and 7, in one embodiment, each connecting assembly 1410 can be locked in the folded position by any suitable locking structure. The anchor assembly 1400 also includes a torsion spring for driving each connecting assembly 1410 to rotate toward the deployed position. The torsion spring is, for example, disposed between each connecting assembly 1410 and the base 1200. When the anchor assembly 1400 is in the folded state, each connecting assembly 1410 is released, and each connecting assembly 1410 automatically pops out due to the reaction force of the torsion spring, switching to the deployed state. The two connecting assemblies 1410 rotate horizontally in opposite directions to rotate from the folded position to the deployed position, or vice versa. The rotation angle of each connecting assembly 1410 is no greater than 90 degrees. In some alternative embodiments, the two connecting assemblies 1410 can rotate horizontally in the same direction to switch between the deployed position and the folded position. Figure 11 shows another embodiment of a portable carrier 1000 according to the first aspect of the present invention.As shown in FIG11 , in this embodiment, anchor assembly 1400 includes at least one latch connector 1422 and at least one webbing 1421. The at least one latch connector 1422 is connected to at least one of the base 1200 and the vehicle body 1100 via the at least one webbing 1421. The at least one latch connector 1422 is used to connect to at least one connection point on a vehicle seat. In this embodiment, referring to FIG11 , anchor assembly 1400 includes two latch connectors 1422 and two webbings 1421. Each of the two webbings 1421 can be connected to the rear side 1160 of the vehicle body 1100. In alternative embodiments, the webbings 1421 can be connected to the rear portion of the base 1200. In other alternative embodiments, two webbing straps 1421 are mounted on the base 1200 and the carrier body 1100, allowing the base 1200 and the carrier body 1100 to be separated from the anchor assembly 1400. As described above, the portable carrier 1000 provided in this aspect is provided with a reinforcement member 1300. Figure 8 is a schematic diagram illustrating the reinforcement member 1300. Referring to Figures 1 and 3, in one embodiment, the reinforcement member 1300 is provided at least on the front side 1140 of the carrier body 1100. Referring to Figures 6 and 8, the reinforcement member 1300 includes a reinforcement portion 1320 and a connecting portion 1310. The connecting portion 1310 is connected to the end of the reinforcement portion 1320 and is connected to the base 1200. The reinforcement portion 1320 abuts against the front side 1140 of the carrier body 1100. The reinforcement portion 1320 and the connecting portion 1310 are substantially perpendicular to each other. Specifically, the connecting portion 1310 extends generally in the front-to-back direction. The reinforcing portion 1320 extends generally parallel to the front side portion 1140, that is, the reinforcing portion 1320 extends generally in the upward direction, that is, the reinforcing portion 1320 extends from the base 1200 toward the top 1170 of the carrier body 1100. During use of the portable carrier 1000, the front side of the portable carrier 1000 is relatively more susceptible to external impacts or collisions. Because the carrier body 1100 is made of a soft fabric sheet, the supporting strength of the carrier body 1100 is relatively low. When the portable carrier 1000 is subjected to external impact, the carrier body 1100 is easily deformed, causing damage to the object (e.g., an animal) contained within the portable carrier 1000.In this embodiment, by providing a reinforcement 1300 on at least the front side 1140 of the carrier body 1100, the reinforcement 1300 can be more effectively utilized to buffer a significant portion of the impact force, thereby limiting deformation of the carrier body 1100 and, in turn, reducing potential damage to items carried within the portable carrier 1000 caused by external impact forces. In other embodiments, reinforcements 1300 may also be provided on at least one of the rear side 1160, left side 1120, or right side 1130 of the carrier body 1100 to further enhance the impact resistance of the carrier body 1100, although this is not a limitation of the present invention. In this embodiment, the front side 1140 of the carrier body 1100 comprises a multi-layer woven fabric structure, and the reinforcement 1320 is located within the front side 1140. By positioning the reinforcement portion 1320 of the reinforcement member 1300 within the front portion 1140, the appearance of the vehicle body 1100 is not affected, and deformation of the vehicle body 1100 under external impact forces can be better limited. The reinforcement portion 1320 is located between the base 1200 and the top 1170 of the vehicle body 1100. Specifically, the end of the reinforcement portion 1320 distal from the connecting portion 1310 does not extend beyond the surface of the top 1170. In some alternative embodiments, the reinforcement portion 1320 is located within the vehicle body 1100 and is aligned with the inner surface of the front portion 1140. This is equivalent to extending the reinforcement portion 1320 from the base 1200 into the load-bearing space and being aligned with the front sidewall of the load-bearing space. In other alternative embodiments, the reinforcement portion 1320 extends outside the vehicle body 1100 and is aligned with the outer side of the front portion 1140. Referring to FIG. 8 , the reinforcement member 1300 is a one-piece molded component, but is not limited thereto. In this embodiment, the reinforcement portion 1320 is integrally formed, and the connecting portion 1310 is integrally formed with the reinforcement portion 1320. The reinforcement member 1300 is made of a hard material, such as a hard alloy (such as stainless steel, aluminum alloy, etc.), plastic, or the like. Specifically, the reinforcement member 1300 is formed by bending a hard tube. In alternative embodiments, the reinforcement member 1300 may not be an integrally formed component. For example, the reinforcement portion 1320 is welded together from multiple components, and the connecting portion 1310 is fixedly connected to the reinforcement portion 1320, or detachably connected to the reinforcement portion 1320, or is integrally formed with at least one component of the reinforcement portion 1320. Continuing with FIG. 8 , in one embodiment, the reinforcement portion 1320 is in an inverted U-shape, but the shape of the reinforcement portion 1320 is not limited to this. The opening of the inverted U-shaped reinforcement portion 1320 faces the base 1200.There are two connecting portions 1310, each connected to the opposite ends of the inverted U-shaped reinforcement portion 1320. In alternative embodiments, the reinforcement portion 1320 may be in an inverted V-shape, an M-shape, a rectangle, or the like, but this is not a limitation of the present invention. Referring to FIG. 1 , the portion of the front portion 1140 not blocked by the reinforcement portion 1320 of the reinforcement member 1300 forms an air-shielded area 1141. This air-shielded area 1141 is provided with a breathable mesh, thereby enhancing the air permeability of the carrying space within the portable portable device 1000. In this embodiment, the opening of the inverted U-shaped reinforcement portion 1320 faces toward the base 1200. The air-shielded area 1141 corresponds to the space enclosed by the inverted U-shaped reinforcement portion 1320 and the base 1200. The breathable mesh at least partially covers the air-shielded area 1141. As shown in FIG6 , the connecting portion 1310 is accommodated within the accommodation space 1230 and is restrained within the accommodation space 1230 by a retaining structure. The retaining structure includes a first retaining portion 1330 disposed on the connecting portion 1310 and a second retaining portion 1240 disposed on the base 1200. The second retaining portion 1240 is located within the accommodation space 1230. The first retaining portion 1330 and the second retaining portion 1240 cooperate with each other to retain the connecting portion 1310 of the reinforcement member 1300 within the accommodation space 1230. Specifically, one of the first retaining portion 1330 and the second retaining portion 1240 is a retaining post 1241, and the other of the first retaining portion 1330 and the second retaining portion 1240 is a retaining hole 1331. The retaining post 1241 is disposed within the retaining hole 1331 to achieve the retaining engagement. In this embodiment, a limiting hole 1331 extends through the connecting portion 1310. A limiting post 1241 is disposed within the housing 1230 and connected to one of the first cover 1210 and the second cover 1220. The other of the first cover 1210 and the second cover 1220 is provided with a fixing hole 1221, which is positioned opposite the limiting post 1241. A portion of a fastener 1250 passes through the fixing hole 1221 and the limiting hole 1331 and is threadedly connected to the limiting post 1241. In alternative embodiments, the limiting post 1241 may not be provided. The first limiting portion 1330 is the limiting hole 1331 provided on the connecting portion 1310, and the second limiting portion 1240 is formed by a fastener 1250. The fastener 1250 passes through the limiting hole 1331 and is threadedly connected to the base 1200.As shown in FIG2 , in one embodiment, to improve the air permeability of the carrying space within the portable vehicle 1000, both the left side 1120 and the right side 1130 of the vehicle body 1100 are provided with breathable mesh. The breathable mesh can be provided on the vehicle body 1100 in a retractable manner, such as by means of a zipper, thereby allowing the carrying space to be opened or closed. When the portable vehicle 1000 is placed on a vehicle seat, the side of the portable vehicle 1000 closest to the vehicle door (i.e., the left side 1120 or the right side 1130 of the portable vehicle 1000) is relatively more susceptible to lateral collisions. Therefore, at least one of the left side 1120 or the right side 1130 has a cushioning area. This cushioning area is provided with a detachable cushioning body 1510. Specifically, the buffer body 1510 is detachably connected to the carrier body 1100 via a connecting mechanism and covers the outer side of the area to be buffered. This cushioning mechanism absorbs external impact forces that may be experienced by the buffer area, thereby reducing the impact damage to the portable carrier 1000 and its carried objects. Referring to Figure 2 , in one embodiment, the area to be buffered may be located only on one of the left side 1120 and the right side 1130 (e.g., the left side 1120 of the carrier body 1100), with the buffer body 1510 detachably covering this area to be buffered. In an alternative embodiment, the areas to be buffered may be located on both the left side 1120 and the right side 1130. In this alternative embodiment, the user can selectively install the buffer body 1510 on the area to be buffered closer to the vehicle door, depending on the placement of the portable carrier 1000 on the vehicle seat; or they can install the buffer body 1510 on both the left side 1120 and the right side 1130. The area where the breathable mesh is located on at least one of the left side portion 1120 and the right side portion 1130 forms the area to be cushioned. Referring to Figures 1 and 2 , in this embodiment, the area where the breathable mesh is located on the left side portion 1120 forms the area to be cushioned. The shape of the cushioning body 1510 matches the shape of the area to be cushioned, which is equivalent to matching the shape of the breathable mesh on the left side portion 1120. In alternative embodiments, the shape of the cushioning body 1510 may not match the shape of the area to be cushioned, as long as the cushioning body 1510 can substantially cover the reinforced area. As shown in Figures 9 and 10 , in one embodiment, the cushioning body 1510 includes a first cushioning layer 1511, a second cushioning layer 1512, and a protective cover 1513. The first cushioning layer 1511 and the second cushioning layer 1512 are stacked. The protective cover 1513 covers the first cushioning layer 1511 and the second cushioning layer 1512.The protective cover 1513 prevents the first and second buffer layers 1511, 1512 of the buffer body 1510 from separating during use and facilitates installation of the buffer body 1510 within the carrier body 1100. The buffer body 1510 has a rear surface 1515 facing the carrier body 1100 and a front surface 1514 facing away from the carrier body 1100. A breathable mesh is provided on the side of the carrier body 1100 facing the buffer body 1510. The side of the protective cover 1513 facing away from the carrier body 1100 forms the front surface 1514 of the buffer body 1510. The first buffer layer 1511 is further away from the carrier body 1100 than the second buffer layer 1512, meaning that the second buffer layer 1512 is closer to the carrier body 1100. In other words, the first buffer layer 1511 is located closer to the end surface 1514 of the buffer body 1510, while the second buffer layer 1512 is located closer to the rear surface 1515 of the buffer body 1510. The first buffer layer 1511 has greater elasticity than the second buffer layer 1512. Specifically, the second buffer layer 1512 is a plate-like structure, made of at least one of EPP foam, EPS foam, and EPO foam. The first buffer layer 1511 is made of foam. This buffer body 1510 can effectively absorb external impact forces while reducing deformation of the breathable mesh of the vehicle body 1100 under external impact forces. Of course, in other embodiments, the buffer body 1510 can also include more buffer layers, such as two or four. Exemplarily, the buffer body 1510 includes a third buffer layer, located between the first buffer layer 1511 and the first buffer layer 1512, or on one side of the first buffer layer 1511. The second buffer layer can be a PE board or an EPP board, for example. As shown in Figures 2 and 9, in one embodiment, the connection mechanism includes a first mating portion 1520 and a second mating portion 1150. The buffer body 1510 is provided with multiple first mating portions 1520, which are disposed on the back surface 1515 of the buffer body 1510. The carrier body 1100 is correspondingly provided with multiple second mating portions 1150. The multiple first mating portions 1520 are adapted to mate with and connect with the multiple second mating portions 1150, so that the buffer body 1510 can substantially cover the area to be cushioned. The multiple first mating portions 1520 are all disposed near the edges of the buffer body 1510. Specifically, the buffer body 1510 is generally elongated, with the first mating portions 1520 disposed at each end.As shown in Figure 2, one of the first and second mating portions 1520 and 1150 is a hook 1521, and the other is a buckle 1151. The hook 1521 is adapted to be hooked onto the buckle 1151. In this embodiment, the first mating portion 1520 provided on the buffer body 1510 is the hook 1521, and the second mating portion 1150 provided on the carrier body 1100 is the buckle 1151. The buckle 1151 may be formed from a webbing 1421 sewn onto the carrier body 1100. In alternative embodiments, the first and second mating portions 1520 and 1150 may be, for example, a pair of Velcro fasteners or press studs provided separately on the carrier body 1100 and the buffer body 1510, although this is not a limitation of the present invention. A second aspect of the present invention provides an improved portable carrier. As described above, portable carriers include, but are not limited to, sleeping boxes, pet carriers, pet baskets, pet backpacks, and other portable carriers suitable for carrying animals. The portable carrier provided in this aspect will be described below using a pet carrier as an example. FIG12 schematically illustrates a portable carrier according to an embodiment of the second aspect of the present invention. FIG13 to FIG15 are top views, side views, and right side views of the portable carrier in FIG12 , respectively. Portable carrier 2000 can be carried on the person and can be attached to a seat in a vehicle such as a train or a car. Portable carrier 2000 is mounted on a vehicle seat in, for example, a longitudinal direction (corresponding to the FB direction in the figure), such that one of its two opposing longitudinal sides is adjacent to the seat backrest and the other is further away from the seat backrest. Hereinafter, the side of portable carrier 2000 adjacent to the seat backrest is referred to as the rear side, and the side of portable carrier 2000 further away from the seat is referred to as the front side. The portable carrier 2000 includes a carrier body 2100 and a base 2200. The carrier body 2100 is positioned above and supported by the base 2200. Together, the carrier body 2100 and the base 2200 form a carrying space for accommodating a pet. The base 2200A is made of a hard material, such as a high-strength polymer material such as polypropylene (PP) or polyethylene (PE). The carrier body 2100 is generally made of a soft material, such as a fabric material such as natural fiber fabric, synthetic fiber fabric, or man-made fiber fabric. Referring to Figures 12 to 15 , the carrier body 2100 has a top 2110, a front side 2120 and a rear side 2130 located on opposite sides in the longitudinal direction, and a left side 2140 and a right side 2150 located on opposite sides in the transverse direction.The top portion 2110 forms the top wall of the carrying space, the front portion 2120 forms the front wall of the carrying space, the rear portion 2130 forms the rear wall of the carrying space, the left side portion 2140 forms the left wall of the carrying space, and the right side portion 2150 forms the outer wall of the carrying space. The support surface of the base 2200 forms the bottom wall of the carrying space. As described below, the base 2200 includes a first cover 2210 and a second cover 2220 (see FIG. 16 ). In this embodiment, the bottom edges of the front portion 2120, rear portion 2130, left portion 2140, and right portion 2150 of the carrier body 2100 are sandwiched between the first cover 2210 and the second cover 2220 of the base 2200. In other embodiments, the carrier body 2100 includes a bottom portion connected to the bottom edges of the front side 2120, rear side 2130, left side 2140, and right side 2150. This bottom portion is sandwiched between the first cover 2210 and the first cover 2220 of the base 2200. In this embodiment, the left side 2140 and right side 2150 of the carrier body 2100 are symmetrically arranged, and therefore, only the right side view of the portable carrier 2000 is shown. It will be appreciated that in other embodiments, the left side 2140 and right side 2150 of the carrier body 2100 may also be asymmetrically arranged. In this embodiment, the portable carrier 2000 also includes a handle 2300 disposed on the top 2110 of the carrier body 2100. The handle 2300 is suitable for being grasped by a user to facilitate lifting or carrying the portable carrier 2000. oIn this embodiment, the handle 2300 is a single handle; in other embodiments, the handle 2300 may be a double handle. As shown in FIG14 , the portable vehicle 2000 further includes an operating member 2400 disposed on the base 2200. The operating member 2400 is operable to switch an anchor assembly (not shown in FIG14 , see FIG9 ) between a folded and unfolded state, or between a locked and unlocked state. The anchor assembly is adapted to connect to a transportation vehicle seat to secure the portable vehicle 2000 thereto. The specific structure and operation of the operating member and anchor assembly will be described in detail below. Referring to FIG16 to FIG18 , the portable vehicle 2000 further includes a reinforcement member 2600 connected to the base 2200. The base 2200 includes a first cover 2210 and a second cover 2220. The first cover 2210 and the second cover 2220 can be detachably connected using fasteners such as screws or bolts, or can also be detachably connected using, for example, a snap-on connection structure. The top of the cover 2210 has a support surface 2211. As described above, the support surface 2211 forms the bottom wall of the load-bearing space. A portion of the reinforcement 2600 is embedded between the first cover 2210 and the first cover 2220, that is, embedded in the base 2200, while another portion of the reinforcement 2600 is embedded in the front side 2120 or the rear side 2130. Specifically, the portion of the reinforcement 2600 extending generally parallel to the support surface 2211 is embedded in the base 2200, while the portion of the reinforcement 2600 extending generally perpendicular to the support surface 2211 is embedded in the front side 2120 or the rear side 2130. In this way, the reinforcement 2600 does not interfere with long objects within the load space, thereby improving the comfort of the load space. The reinforcement 2600 is made of a high-strength material. High-strength materials include, but are not limited to, high-strength steel, high-strength plastic, high-strength aluminum alloy, and high-strength fiber materials. The reinforcement 2600 has high structural strength and good toughness, capable of withstanding high pressure and impact. The reinforcement 2600 can be formed by bending high-strength tubing. In the embodiment of the second aspect, the reinforcement 2600 can serve as an anti-collision function and can therefore also be referred to as an anti-collision member. Correspondingly, the first reinforcement 2610 and the second reinforcement 2620 can also be referred to as the first anti-collision member and the second anti-collision member. The reinforcement 2600 includes a first reinforcement 2610 and a second reinforcement 2620. A portion of the first reinforcement 2610 is disposed on the front side 2120 of the carrier body 2100, while another portion of the first reinforcement 2610 is connected to the base 2200.First, a portion of the reinforcement 2620 is disposed on the rear side 2130 of the carrier body 2100, while another portion of the second reinforcement 2620 is connected to the base 2200. Because the carrier body 2100 is generally made of a soft fabric sheet, its support strength is relatively low. When the portable carrier 2000 is subjected to an external impact, the carrier body 2100 is susceptible to deformation, potentially causing harm to the pet carried within. In this embodiment, by disposing the first reinforcement 2610 and the second reinforcement 2620 on the front side 2120 and rear side 2130 of the carrier body 2100, respectively, the first reinforcement 2610 and the second reinforcement 2620 can effectively absorb most of the impact force, thereby limiting deformation of the carrier body 2100 and reducing potential harm to the pet carried within the portable carrier 200000. Specifically, as previously described, the portable vehicle 2000 is mounted longitudinally to the vehicle's seat, with one of its two longitudinally opposing sides positioned closer to the seat's backrest and the other further away. First reinforcements 2610 and 2620 are respectively disposed on opposite longitudinal sides of the portable vehicle 2000, i.e., closer to and further away from the seat's backrest. These sides are the primary load-bearing surfaces of the portable vehicle 2000 when the vehicle experiences an emergency stop or collision. In the event of an emergency stop or collision, the first reinforcements 2610 and second reinforcements 2620 disposed on opposite longitudinal sides of the portable vehicle 2000 provide enhanced collision protection, dispersing the impact force and thereby reducing damage to the pet within the portable vehicle 2000. The first reinforcements 2610 and second reinforcements 2620 have similar structures. The first reinforcement 2610 includes a first reinforcement portion 2611 and a first connecting portion 2612 extending from the first reinforcement portion 2611. The second reinforcement 2620 includes a second reinforcement portion 2621 and a second connecting portion 2622 extending from the second reinforcement portion 2621. The first connecting portion 2612 is substantially perpendicular to the first reinforcement portion 2611, while the second connecting portion 2622 is substantially perpendicular to the second reinforcement portion 2621. Specifically, the first reinforcement portion 2611 and the second reinforcement portion 2621 extend substantially perpendicularly to the support surface 2211 from the base 2200 toward the top 2110 of the vehicle body 2100. The first connecting portion 2612 and the second connecting portion 2622 extend substantially in the longitudinal direction and parallel to the support surface 2211. The first connecting portion 2612 and the second connecting portion 2622 are adapted to be connected to the base 2200.In this embodiment, the first connecting portion 2612 and the second connecting portion 2622 are connected to the first cover 2210 of the base 2200. In other embodiments, the first connecting portion 2612 and the second connecting portion 2622 may also be connected to the second cover 2220 of the base 2200. The first connecting portion 2612 and the second reinforcing portion 2621 are connected together. For example, one of the wooden ends of the first connecting portion 2612 and the wooden ends of the second connecting portion 2622 is sleeved onto the other of the wooden ends of the first connecting portion 2612 and the ends of the second connecting portion 2622, and the sleeved portions of the ends of the first connecting portion 2612 and the ends of the second connecting portion 2622 are secured by fasteners. For example, referring to FIG18 , an assembly hole 2630, such as a screw hole, is provided at the portion where the end of the first connecting portion 2612 and the end of the second reinforcing portion 2621 interlock. Fasteners 2640, such as screws or bolts, pass through the assembly hole 2630 to securely connect the end of the first connecting portion 2612 and the end of the first reinforcing portion 2621. In this embodiment, the first reinforcing member 2610 and the second reinforcing member 2620 of the reinforcement member 2600 are separate components. The end of the first reinforcing member 2610 (i.e., the end of the first connecting portion 2612) and the end of the second reinforcing member 2620 (i.e., the end of the second reinforcing portion 2621) are secured together by interlocking, forming an integrated structure. This integrated structure of the reinforcement member 2600 further enhances its structural strength and provides a cushioning effect. In other embodiments, the end of the first reinforcement member 2610 (i.e., the end of the first connecting portion 2612) and the end of the second reinforcement member 2620 (i.e., the end of the second reinforcement portion 2621) can be secured together by welding, bonding, or other fastening structures. In other embodiments, the first reinforcement member 2610 and the second reinforcement member 2620 can be integrally formed. That is, the reinforcement member 2600 is a single component, eliminating the need to assemble the first reinforcement member 2610 and the second reinforcement member 2620 together before attaching the reinforcement member 2600 to the base 2200. In this embodiment, the reinforcement member 2600 is secured to the first cover 2210 of the base 2200 via a fastening structure. The fastening structure includes studs 2230 disposed on the lower surface of the first cover 2210 and fixing holes 2650 provided in the reinforcement member 2600. A plurality of studs 2230 are provided on the lower surface of the first cover 2210 , and fixing holes 2650 corresponding to the positions of the studs 2230 are provided on the first connecting portion 2612 and the second connecting portion 2622 .Fasteners, such as screws, are adapted to pass through the fixing holes 2650 of the first and second connecting portions 2612, 2622 and threadably engage with the studs 2230, thereby securing the first and second reinforcement members 2610, 2620 to the lower surface of the first cover 2210. In other embodiments, the lower surface of the first cover 2210 may be provided with multiple screw holes, instead of the multiple studs 2230. Fasteners, such as screws, are adapted to pass through the fixing holes 2650 of the first and second connecting portions 2612, 2622 and threadably engage with the screw holes. In other embodiments, the first and second reinforcement members 2610, 2620 may also be secured to the lower surface of the first cover 2210 by welding, bonding, or other methods. In this embodiment, the reinforcement member 2600 is attached to the lower surface of the first cover 2210 of the base 2200. In other embodiments, the reinforcement member 2600 may also be attached to the upper surface of the second cover 2220 of the base 2200. In this embodiment, the first reinforcement portion 2611 of the first reinforcement member 2610 and the second reinforcement portion 2621 of the second reinforcement member 2620 are both arranged substantially perpendicular to the support surface 2211 and are respectively located within the front portion 2120 and the rear portion 2130. In this embodiment, both the front portion 2120 and the rear portion 2130 of the vehicle body 2100 are multi-layer woven fabric structures. Disposing the first reinforcement portion 2611 and the second reinforcement portion 2621 within the front portion 2120 and the rear portion 2130, respectively, within the multi-layer woven fabric structures of the front portion 2120 and the rear portion 2130, does not affect the appearance of the vehicle body 2100 while effectively limiting deformation of the vehicle body 2100 under external impact forces. In other embodiments, the first reinforcement portion 2611 may be disposed on the exterior of the front portion 2120 in close contact with the inner surface of the front portion 2120, while the second reinforcement portion 2621 may be disposed on the exterior of the rear portion 2130 in close contact with the inner surface of the rear portion 2130. In other words, the first reinforcement portion 2611 and the second reinforcement portion 2621 extend from the base 2200 into the carrying space and are respectively in close contact with the front and rear sidewalls of the carrying space. In still other embodiments, the first reinforcement portion 2611 may be disposed on the exterior of the front portion 2120 in close contact with the outer surface of the front portion 2120, while the first reinforcement portion 2621 may be disposed on the exterior of the rear portion 2130 in close contact with the outer surface of the rear portion 2130. The first reinforcement portion 2611 of the first reinforcement member 2610 and the second reinforcement portion 2621 of the second reinforcement member 2620 extend upward from the front edge and the rear edge of the base 2200 , respectively, and extend into the front side portion 2120 and the rear side portion 2130 , respectively.In this embodiment, the first reinforcement portion 2611 and the second reinforcement portion 2621 have the same structure. In other embodiments, the first reinforcement portion 2611 and the second reinforcement portion 2621 may have different structures. Referring to FIG18 , in this embodiment, the first reinforcement portion 2611 and the second reinforcement portion 2621 both have an inverted U-shaped structure. The first reinforcement portion 2611 includes two opposing first parallel portions 2611a and a first connecting portion 2611b for connecting one end of the two first parallel portions 2611a. The second reinforcement portion 2621 includes two opposing second parallel portions 2621a and a second connecting portion 2621b for connecting one end of the two second parallel portions 2621a. The first reinforcement member 2610 includes two first connecting portions 2612, each extending from the other end of the two first parallel portions 2611a of the inverted U-shaped structure of the first reinforcement portion 2611. The second reinforcement 2620 includes two second connecting portions 2622, each extending from the other end of the two second parallel portions 2621a of the inverted U-shaped structure of the second reinforcement 2621. The two parallel portions 611a and 621a of the inverted U-shaped structure of each of the first reinforcement 2611 and the second reinforcement 2621 are located near the left side 2140 and the right side 2150, respectively, while the connecting portions 611b and 621b are located near the top 2110. In other embodiments, the first reinforcement 2611 or the second reinforcement 2621 may have an inverted V-shape, an M-shape, or a rectangular structure. Figure 19 illustrates a portable vehicle according to another embodiment of the present invention, with the vehicle body removed. In this embodiment, the portable vehicle 2000 also includes a first support bar 2710, which is connected to the base 2200 and disposed adjacent to or within the front side 2120. Specifically, the first support bar 2710 has an inverted U-shaped structure, with its ends connected to the ends of the front edge of the base 2200. In this embodiment, the first support bar 2710 is embedded within the edges of the top 2110, left side 2140, and right side 2150 adjacent to the front side 2120. Similar to the front side 2120 and rear side 2130, the top 2110, left side 2140, and right side 2150 are all multi-layer woven structures. Positioning the first support bar 2710 within the edges of the top 2110, left side 2140, and right side 2150 adjacent to the front side 2120 does not affect the appearance of the carrier body 2100 while providing better support for the carrier body 2100.In other embodiments, the first support bar 2710 can be embedded within the edges of the front portion 2120, adjacent to the top 2110, the left portion 2140, and the right portion 2150. The first support bar 2710 is made of a highly resilient material. Highly resilient materials include, but are not limited to, highly resilient steel, highly resilient plastic, highly resilient aluminum alloy, highly resilient fiber materials, or other materials that can quickly recover their original shape and size after being subjected to external forces. For example, the first support bar 2710 can be an iron bar or a plastic steel bar. The second support bar 2710 has high elasticity and excellent mechanical properties. The provision of the first support bar 2710 can provide a more rigid connection between the top 2110, the left side 2140, and the right side 2150 and the front side 2120. Consequently, the entire carrier body 2100 is more rigid. Specifically, the carrier body 2100 is better supported and less prone to deformation. In particular, even if the top collapses and deforms under pressure from a heavy object, it returns to its original position after the object is removed, ensuring that the top remains straight and does not collapse. In this embodiment, only the first support bar 2710 is provided adjacent to or within the front side 2120. It will be appreciated that in other embodiments, the first support bar 2710 may be provided adjacent to or within the rear side 2130. In other embodiments, a first support bar 2710 may be provided adjacent to or within the left side portion 2140, and / or adjacent to or within the right side portion 2150. FIG20A illustrates a portable carrier according to another embodiment of the present invention. In this embodiment, the front portion 2120 of the portable carrier 2000 is provided with a front cover 2121. The front cover 2121 is adapted to selectively open or close a front window defined in the front portion 2120. When the front cover 2121 is open, a pet can be placed in the carrier body 2100, for example. Or, remove the pet from the carrier body 2100. The bottom edge of the front cover 2121 is fixed to the bottom end of the front side portion 2120, and the side and top edges of the front cover 2121 are connected to the front side portion 2120 via, for example, a zipper. In this embodiment, the portable carrier 2000 also includes a second support bar 2720. The location of the second support bar 2720 is schematically indicated by a dashed line in FIG20A. The second support bar 2720 is disposed in the front side portion 2120 and is not visible from the outside of the portable carrier 2000. The second support bar 2720 is connected to the base 2200 and extends along the side and top edges of the front cover 2121 to support the front window enclosed by the front cover 2121. Referring to FIG20B, the second support bar 2720 has a similar structure to the first support bar 2710 and can be made of similar materials, so further description is omitted. In other embodiments, when the rear side portion 2130 of the vehicle body 2100 is provided with a rear window and a corresponding rear cover for closing the rear window, the rear side portion 2130 may also be provided with a first support bar 2720, similar to the front side portion 2120. In other embodiments, when a first reinforcement member 2610 is provided around the front window of the front side portion 2120, the second support bar 2720 surrounding the front window may not be required because the first reinforcement member 2610 provides a certain degree of support for the front window. Accordingly, when a second reinforcement member 2620 is provided around the rear window of the rear side portion 2130, the second support bar 2720 surrounding the rear window may also not be required. Referring to FIG. 21 , as described above, the portable vehicle 2000 further includes an anchor assembly 2500, which is provided at the rear of the base 2200. Anchor assembly 2500 is used to secure portable carrier 2000 to a seat in a vehicle, such as a train or car. Connecting assembly 2510 of anchor assembly 2500 includes ISOFIX connectors that comply with the ISOFIX standard and LATCH connectors that comply with the LATCH standard. Accordingly, the vehicle seat is equipped with an ISOFIX interface or a LATCH interface to connect with the ISOFIX or LATCH connectors of portable carrier 2000. In this embodiment, connecting assembly 2510 of anchor assembly 2500 is an ISOFIX connector. In other embodiments, connecting assembly 2510 of anchor assembly 2500 may be a LATCH connector.In this embodiment, the anchor assembly 2500 includes two connecting assemblies 2510. Both connecting assemblies 2510 are pivotally connected to the rear portion of the base 2200, enabling transition between a deployed position (also referred to as a use position) and a folded position. When the connecting assemblies 2510 are in the folded position, the anchor assembly 2500 is in a folded state. When the connecting assemblies 2510 are in the deployed position, the anchor assembly 2500 is in an deployed state. The connecting assemblies 2510 in the deployed position are suitable for connection to the ISOFIX interface of a vehicle seat. The connecting assemblies 2510 have a locked state, enabling engagement with the connector of the vehicle seat's ISOFIX interface, and an unlocked state, enabling separation from the connector. When the connecting assemblies 2510 are not locked with the connector, they remain in the unlocked state. Specifically, when the connecting assemblies 2510 are in the folded position, the connecting assemblies 2510 are in the unlocked state. During material transfer, when the connecting assembly 2510 is locked with the connector, the connecting assembly 2510 is driven by the connector to switch to the locked state. Referring to Figures 22 and 23 , the anchor assembly 2500 also includes a locking member 2520 connected to the connecting assembly 2510. The locking member 2520 is slidably mounted on the base 2200 and is movable relative to the base 2200 between a locked position and a released position. When the locking member 2520 is in the locked position, it is locked to the connecting assembly 2510, restricting its movement. When the locking member 2520 is in the released position, the locking member 2520 is released from the connecting assembly 2510. In this embodiment, two locking members 2520 are provided, corresponding to two connecting assemblies 2510. The following description uses one set of connecting assemblies 2510 and locking members 2520 as an example. The connecting assemblies 2510 and locking members 2520 can be controlled by the operating member 2400. Operating member 2400 is operably disposed at the front of base 2200 and connected to locking member 2520. When connecting assembly 2510 is in different positions, operating member 2400 causes connecting assembly 2510 to respond in different ways. Specifically, when connecting assembly 2510 is in the collapsed position, locking member 2520 is locked with connecting assembly 2510. Operating member 2400 switches locking member 2520 from the locked position to the unlocked position, releasing the locking member 2520 from connecting assembly 2510. Connecting assembly 2510 automatically springs out from the collapsed position to the expanded position under the action of the elastic return member.When the connecting assembly 2510 is in the deployed position and locked with the connector of the 1S0F1X interface, operating the operating member 2400 automatically switches the connecting assembly 2510 from the locked state to the unlocked state, allowing the connecting assembly 2510 to be separated from the connector. When the operating member 2400 is operated while the connecting assembly 2510 is in the deployed position and unlocked, the connecting assembly 2510 and the locking member 2520 do not respond; that is, the connecting assembly 2510 remains in the deployed position and unlocked state. The anchoring assembly 2500 also includes a first pulling member 2530, a second pulling member 2540, and a linkage member 2550. The operating member 2400 is connected to the first pulling member 2530 and the second pulling member 2540 via the linkage member 2550. One end of the first pulling member 2530 is connected to the linkage member 2550, and the other end of the first pulling member 2530 is connected to the locking member 2520. One end of the second pulling member 2540 is connected to the linkage member 2550, and the other end of the second pulling member 2540 passes through the locking member 2520 and is connected to the connecting assembly 2510. Both the first pulling member 2530 and the second pulling member 2540 can be made of flexible and deformable wires, such as steel wire or carbon fiber wire. The linkage member 2550 is pivotally connected to the base 2200 and movably connected to the operating member 2400. The operating member 2400 is movable between a driven position and an initial position, with the movement direction of the operating member 2400 being generally parallel to the longitudinal direction. "Operating the operating member" mentioned above means moving the operating member 2400 from the initial position to the driven position. During the movement of the operating member 2400 from the initial position to the driven position, the operating member 2400 drives the linkage member 2550 to pivot. This pivoting of the linkage member 2550, through the first pulling member 2530 and the second pulling member 2540, respectively, drives the locking member 2520 and the connecting assembly 2510 to respond. Specifically, when the operating member 2400 is operated, the operating member 2400 drives the linkage member 2550 to pivot, and the linkage member 2550 drives the locking member 2520 to move from the locked position to the unlocked position via the first pulling member 2530. In particular, when the connecting assembly 2510 is in the folded position, when the linkage member 2550 pivots and drives the locking member 2520 to move to the unlocked position via the first pulling member 2530, the locking member 2520 is released from the connecting assembly 2510, and the connecting assembly 2510 automatically pops out to the deployed position under the action of the return member.On the other hand, when the operating member 2400 is operated, the operating member 2400 causes the linkage member 2550 to pivot, which, via the second guide member 2540, drives the connection assembly 2510 from the locked state to the unlocked state. Specifically, when the connection assembly 2510 is in the locked state, the linkage member 2550 pivots, driving the connection assembly 2510 to the unlocked state via the second guide member 2540, thereby releasing the connection assembly 2510 from the connector. During this process, the connection assembly 2510 remains in the deployed position. When the connection assembly 2510 switches to the unlocked state, the second guide member 2540 is in a relaxed state. Therefore, even if the operating member 2400 is operated to cause the linkage member 2550 to pivot, the linkage member 2550 cannot cause the second guide member 2540 to move as a whole, or can only cause the second guide member 2540 to move very slightly as a whole, causing the connection assembly 2510 to remain in the unlocked state. Figure 24 illustrates a portable carrier according to yet another embodiment of the present invention. In this embodiment, the handles 2300 are double handles. To improve the air permeability of the carrying space, in this embodiment, at least one of the top 2110, front 2120, rear 2130 (not shown in FIG. 24 ), left 2140, and right 2150 (not shown in FIG. 24 ) of the carrier body 2100 is provided with a window. Covers can be provided at these windows to open or close them. When the windows are opened, pets can be placed in or removed from the carrier body 2100. A hollow area is formed in at least one of the top 2110, front 2120, rear 2130, left 2140, and right 2150 of the carrier body 2100, and this hollow area is covered with a breathable mesh 2800. FIG24 shows a breathable mesh 2800 disposed on the top 2110, front 2120, and left 2140. It also shows a top cover 2111 disposed on the top 2110 and a left cover 2141 disposed on the left 2140. It is understood that the breathable mesh 2800 may also be disposed on the rear 2130 and right 2150. It is also understood that a cover may also be disposed on the right 2150. In other embodiments, the front 2120 and rear 2130 may also be disposed on the cover. Referring to the top 2110 and left 2140 in FIG24 , the breathable mesh 2800 may be formed on the cover (top cover 2111 and left cover 2141), meaning that at least a portion of the cover is provided with the breathable mesh 2800.The provision of the breathable mesh 2800 ensures that the carrying space remains closed while also improving the air permeability of the carrying space, thereby improving the environment for the pet in the carrying space and enhancing the pet's comfort. A second aspect of the present invention provides an improved portable carrier. As described above, portable carriers include, but are not limited to, sleeping boxes, pet carriers, pet baskets, pet backpacks, and other portable carriers suitable for carrying animals. The portable carrier provided in this aspect will be described below using a pet backpack as an example. Figures 25 to 29 illustrate a portable carrier 3000 according to an embodiment of the third aspect of the present invention. The connecting assembly 3410 of the anchor assembly 3400 of the portable carrier 3000 in Figures 25 and 28 is in a folded position, while the connecting assembly 3410 of the anchor assembly 3400 in Figures 26, 27, and 29 is in an extended position. The portable carrier 1000 has a carrying space for accommodating an animal. The portable carrier 1000 can be carried (e.g., carried in one's hand or slung across one's back) and can be attached to a seat in a vehicle such as a train or car. The portable carrier 3000 includes a carrier body 3100 and a base 3200. The carrier body 3100 is positioned adjacent to the base 3200, and the carrier body 3100 and the base 3200 together form a carrying space for accommodating an animal. The base 3200 is, for example, made of a rigid material to support the carrier body 3100. The carrier body 3100 may include a fabric sheet or other material that encloses the carrying space. The portable carrier 3000 also includes a shoulder strap assembly 3190, which is attached to the carrier body 3100. This makes it easy to carry a pet, especially when traveling, hiking, or riding public transportation, without having to carry it by hand. Compared to handheld portable carriers, the shoulder strap assembly 3190 distributes the overall weight of the portable carrier 3000 and the pet contained therein across the shoulders and back, reducing fatigue during prolonged carrying. The shoulder strap assembly 3190 also provides greater stability when carrying a pet, reducing the pet's swaying within the carrying space. As shown in Figures 25 to 29, the carrier body 3100 includes a top portion 3170, a front portion 3140, a left portion 3120, a right portion 3130, and a rear portion 3160. The top portion 3170 forms the top wall of the carrying space, the front portion 3140 forms the front wall of the carrying space, the left portion 3120 forms the left wall of the carrying space, the right portion 3130 forms the right wall of the carrying space, and the rear portion 3160 forms the rear wall of the carrying space.As shown in Figures 25 and 26 , the shoulder strap assembly 3190 is disposed on the rear portion 3160 and includes a first shoulder strap 3191 and a second shoulder strap 3192. The upper ends of the first and second shoulder straps 3191, 3192 are connected to the rear portion 3160 of the carrier body 3100 near the top 3170, or at the junction of the rear portion 3160 and the top 3170. This position provides a secure connection, ensuring that the first and second shoulder straps 3191, 3192 can withstand the weight of the portable carrier 3000. The lower ends of the first and second shoulder straps 3191, 3192 are connected to the underside of the rear portion 3160, or at the junction of the underside of the rear portion 3160 with the left side portion 3120 and the right side portion 3130, respectively. As shown in Figure 25, the lower end of the first shoulder strap 3191 is connected to the lower side of the rear portion 3160 at the junction with the left side portion 3120, while the lower end of the second shoulder strap 3192 is connected to the lower side of the rear portion 3160 at the junction with the right side portion 3130. In some embodiments, the ends of the first shoulder strap 3191 and the second shoulder strap 3192 at these junctions can be fixed or connected to the carrier body 3100 via metal or plastic buckles, allowing the lengths of the first and second shoulder straps 3191, 3192 to be adjusted. The first and second shoulder straps 3191, 3192 are arranged symmetrically on either side of the rear portion 3160, extending diagonally downward from the top to the bottom of the carrier body 3100. This evenly distributes the weight of the portable carrier 3000 and reduces the burden on the shoulders. In some embodiments, the first and second shoulder straps 3191, 3192 can be secured to the top portion 3170 and the rear portion 3160 by sewing. In some embodiments, the first and second shoulder straps 3191 and 3192 can be double-stitched, meaning they are secured with two parallel lines. This effectively distributes pressure and prevents seam breakage. In some embodiments, the connection points between the first and second shoulder straps 3191 and 3192 and the top portion 3170 and rear portion 3160 can be sewn with multiple layers of fabric to enhance structural strength. These layers can be reinforced canvas, nylon, or leather, providing additional support and durability. In some embodiments, the first and second shoulder straps 3191 and 3192 can be secured to the top portion 3170 and rear portion 3160 using rivets. This allows them to withstand significant weight and pressure, exhibits excellent corrosion resistance, is suitable for outdoor use, and enhances the aesthetics of the portable carrier 3(X)0. In some embodiments, the shoulder strap assembly 3190 can have only one shoulder strap.When using a single shoulder strap, the portable carrier 3000 can be carried cross-body, allowing for quick access. In some embodiments, the shoulder strap assembly 3190 can have more than two shoulder straps. When using multiple shoulder straps, the portable carrier 3000 can be carried in a customized manner. In some embodiments, each of the first and second shoulder straps 3191, 3192 is padded on the inside to increase comfort and reduce shoulder strain. The padding can be foam. Padding can be provided along the entire length of the first and second shoulder straps 3191, 3192 to provide uniform support and comfort. Alternatively, padding can be provided only in the middle portion of the first and second shoulder straps 3191, 3192 (i.e., the portion that directly contacts the shoulders) to reduce material weight while providing support in specific areas. The thickness of the padding can be adjusted to accommodate varying load requirements. The cushions are either directly mounted within the first and second shoulder straps 3191 and 3192, or removably mounted thereon, allowing installation or removal as needed. The outer layer of the cushions can be made of a breathable material, such as a mesh fabric, to enhance air circulation and reduce leakage and discomfort during prolonged use. In some embodiments, the bottom wall of the carrying space is formed by the base 3200, with the front side 3140, left side 3120, right side 3130, and rear side 3160 respectively connected to the base 3200. In some embodiments, as shown in Figures 31 and 32, the carrier body 3100 has a bottom 3150 secured within the base 3200 to ensure a secure connection between the carrier body 3100 and the base 3200, preventing any loosening. In some embodiments, as shown in Figures 31 and 32, the bottom 3150 forms the bottom wall of the carrying space 110. In some embodiments, the first cover 3210 and the second cover 3220 are respectively located on either side of the bottom 3150 of the carrier body 3100. The first cover 3210 is located on the side of the bottom 3150 of the carrier body 3100 facing the carrying space, while the first cover 3220 is located on the side of the bottom 3150 of the carrier body 3100 facing away from the carrying space. In other words, the first cover 3210 is located within the carrying space, while the second cover 3220 is located outside the carrying space. In some embodiments, the first cover 3210 and the second cover 3220 are each provided with a limiting portion and a positioning portion. The cooperation of the limiting portion and the positioning portion allows the bottom 3150 of the carrier body 3100 to be clamped between the first cover 3210 and the second cover 3220, thereby ensuring the positioning of the carrier body 3100 and the base 3200.When the first cover 3210 and the second cover 3220 are fastened together, the first cover 3210 serves as the bottom wall of the carrying space, supporting the pet. In some embodiments, the left side 3120, right side 3130, front side 3140, back side 3160, top 3170, and bottom 3150 can all be made of soft materials (e.g., fabric) and sewn together. Fabric materials such as nylon, polyester, and canvas offer advantages such as durability, lightness, and waterproofness. In some embodiments, to give the portable carrier 3000 a more upright appearance, EVA (ethylene vinyl acetate) or EPP (expanded polypropylene) can be foamed into sheets. The fabric can be attached, baked, and then pressed into shape. Finally, the fabric can be sewn together or connected with a zipper to form the body. The portable vehicle body 3100 of the portable vehicle 3000 is supported by EVA or EPP materials, maintaining an upright shape and resisting deformation, resulting in a more aesthetically pleasing appearance. EVA is soft and elastic, offering excellent cushioning and impact resistance, while EPP offers excellent impact resistance and durability. In some embodiments, the left side 3120, right side 3130, front side 3140, rear side 3160, top 3170, and bottom 3150 can all be made of thermoplastic polyurethane (TPU), polyester, high-density composite materials, waterproof nylon, or coated nylon and joined together through seamless bonding. This creates a unified vehicle body structure, minimizing the presence of seam holes, significantly improving waterproofing, and reducing the risk of seam wear and unraveling. In some embodiments, adhesives such as polyurethane adhesives, hot melt adhesives, epoxy resin adhesives, acrylic adhesives, and silicone adhesives are used for seamless bonding, providing highly reliable adhesion and resisting detachment. In some embodiments, the vehicle body 3100 can be printed integrally using 3D printing, or the left side 3120, right side 3130, front side 3140, rear side 3160, top 3170, and bottom 3150 can be 3D printed separately and then assembled into the vehicle body 3100 by gluing, welding, plugging, etc. As shown in Figures 25 to 29, at least one window door is provided on the vehicle body 3100, that is, a window is provided on one or more of the left side 3120, right side 3130, front side 3140, rear side 3160, and top 3170, and the window is covered with a window body.In some embodiments, a window is provided on the right side 3130, with a right window 3131 disposed thereon; a window is provided on the left side 3120, with a left window 3121 disposed thereon; a window is provided on the top 3170, with a top window 3171 disposed thereon; and a window H is provided on the front side 3140, with a front window 3141 disposed thereon. The window door can be circular, rectangular, or other shapes. To prevent the edges of the windows from fraying or breaking, they are reinforced, for example, using reinforcing strips, hemming, or heat pressing. Each window is made of breathable mesh, such as nylon mesh, polyester mesh, or other durable mesh materials, to meet air permeability requirements. The windows can be designed to be transparent or translucent, for example, using transparent or translucent mesh, to facilitate light and air permeability while ensuring the comfort of the pet inside. Thus, the provision of windows and frames provides ventilation or viewing functions. In some embodiments, the front window 3141 can be secured to the edge of the window of the front portion 3140 by sewing, gluing, or heat pressing. The top window 3171 can be connected to the top portion 3170 via a zipper, and / or the left window 3121 can be connected to the left portion 3120 via a zipper, and / or the right window 3131 can be connected to the right portion 3130 via a zipper, allowing the corresponding windows to be opened and closed, thereby facilitating the entry and exit of pets. In some embodiments, each window can be provided with a waterproof coating or waterproof zipper to effectively prevent water from entering the load space while maintaining ventilation. In some embodiments, each window can be provided with a multi-layer structure, with an inner layer of breathable mesh and an outer layer of a removable windproof and waterproof cover. As shown in Figure 30, a buffer 3500 is provided at at least one window to provide impact protection. This buffer 3500 can enhance lateral impact resistance. In some embodiments, the buffer body 3500 can be made of EVA foam, which offers excellent softness and cushioning properties, making it suitable for side impact protection. The elasticity and compressive strength of EVA foam effectively absorb energy during collisions, mitigating damage to the portable vehicle 3000 and the pet inside. In some embodiments, the buffer body 3500 can be made of EPP polypropylene foam, which offers high toughness and excellent impact resistance. EPP polypropylene foam quickly recovers after impact, making it suitable as the core material for side impact protection, particularly for applications requiring long-term use and sustained protection after multiple impacts.In some embodiments, the buffer body 3500 can be made of TPU (thermoplastic polyurethane), resulting in extremely high wear resistance, impact resistance, and elasticity. TPU is suitable for side impact protection with a higher level of protection. TPU maintains its flexibility even in low-temperature environments, making it suitable for outdoor use. In some embodiments, the buffer body 3500 can be directly molded with the corresponding window through injection molding or hot pressing. This integral molding of the buffer body and window not only ensures structural strength but also reduces joints, thereby avoiding weak points or vulnerable areas during side impacts. The integrally molded buffer body 3500 is structurally stable, strong, and reliable, effectively resisting external impacts. Furthermore, since the buffer body 3500 is integrated with the window, it has a simpler appearance and improved waterproof and dustproof properties. In some embodiments, the buffer body 3500 can be flexibly attached and detached from the corresponding window through the use of detachable connections such as Velcro, zippers, or snaps. Velcro or zippers facilitate quick installation and replacement, while buckles provide a more secure fastening method. The detachable Velcro fastener facilitates daily use, allowing users to freely attach and detach the buffer body 3500 as needed, particularly facilitating maintenance when high-strength protection is not required. The detachable zipper fastener allows for easy removal or replacement of the buffer body 3500 when needed, making it particularly suitable for cleaning or replacement. The detachable buckle fastener method is suitable for applications requiring high-strength and secure fastening, preventing the buffer body 3500 from loosening or falling due to external forces. In some embodiments, the buffer body 3500 can be designed as a two-layer structure, with an inner layer serving as a base protective structure permanently fixed to the window and an outer layer detachably attached. This design balances robustness and flexibility, allowing for easy replacement of the outer layer if damaged or requiring an upgrade without altering the overall structure. In some embodiments, the buffer body 3500 can be arc-shaped, square, rectangular, honeycomb-shaped, or other shapes. The arc-shaped buffer body 3500 can better conform to the curved surface of the portable vehicle 3000 and disperse the impact force during an impact. The arc-shaped buffer body 3500 can effectively guide the distribution of external forces during a collision, reducing the direct impact on the portable vehicle 3000 and the pet inside. A square or rectangular buffer body 3500 can cover a larger surface area, providing better protection. Furthermore, a square or rectangular buffer body 3500 is more stable and can evenly distribute the impact force. A honeycomb-shaped buffer body 3500 can be lightweight and effectively absorb impact energy.The honeycomb-shaped buffer body 3500 helps reduce the overall weight of the portable carrier 3000 while ensuring strength. In some embodiments, the buffer body 3500 can be smaller than the corresponding window. When the buffer body 3500 is smaller than the window, the buffer body 3500 only covers the central area of ​​the window. The shape of the buffer body 3500 can be consistent with the window. When the buffer body 3500 is smaller than the window, the overall weight of the portable carrier 3000 can be reduced because the buffer body 3500 covers a smaller area and uses less material. This is beneficial for portability and lightweight design. In addition, the buffer body 3500 is smaller than the window, allowing the edges of the window to still function as light- and air-permeable areas. This is particularly suitable for applications where full coverage is not required. For example, the edges of a window made of breathable mesh can still allow air to circulate while the central area is provided with additional protection. In some embodiments, the buffer body 3500 can be larger than the window, allowing the buffer body 3500 to not only cover the entire window but also extend beyond the window to cover a portion of the material surrounding the window. A buffer body 3500 that is larger than the window can better protect the window and surrounding structures, especially in high-force side impacts, by absorbing and dissipating the impact. This buffer body 3500 provides more effective side impact protection for the portable vehicle 3000, not only protecting the window but also reducing stress on surrounding materials. Because the buffer body 3500 extends beyond the window, it provides additional support for the surrounding connecting structures, enhancing the stability and rigidity of the entire portable vehicle 3000. This size relationship is particularly useful for designs that require enhanced overall structural strength for the portable vehicle 3000. In some embodiments, the size of the buffer body 3500 can be completely consistent with the dimensions of the window. The buffer body 3500 covers the entire area of ​​the window without extending beyond or undercutting it. The buffer body 3500 seamlessly conforms to the edges of the window and is typically designed to mirror the window's shape. A buffer body 3500 that conforms to the window's dimensions provides comprehensive protection while maintaining the overall clean appearance of the portable vehicle 3000. Regardless of which part of the window is impacted, the buffer body 3500 effectively absorbs and disperses the impact force, preventing damage. This buffer body 3500, designed to fit the window's dimensions, provides a balanced solution, protecting all parts of the window without making the buffer body 3500 appear overly prominent, ensuring that the portable carrier 3000 strikes a balance between protection and aesthetics.In some embodiments, the buffer body 3500 can be detachably connected to the window or to the main carrier structure outside the window. Since the main carrier structure outside the window is stronger than the window, the connection strength between the carrier body and the buffer body 3500 can be increased, thereby enhancing the impact protection provided to the window. To ensure a smooth transition between the buffer body 3500 and the window, the thickness of the buffer body 3500 should be close to that of the window. This ensures a harmonious design, neither too thick to create a bulky appearance nor too thin to compromise protection. In some embodiments, the window may be very thin (such as breathable mesh), while the buffer body 3500 can be designed to be slightly thicker to enhance impact protection. In this case, the buffer body 3500 can protrude from the window surface to form a buffer zone, reducing the direct impact of impact on the window. In some embodiments, as shown in FIG30 , a buffer body 3500 is provided at the window of the right side portion 3130 and the window of the front side portion 3140, respectively. In some embodiments, as shown in FIG25 to FIG27 , the portable carrier 3000 is equipped with a handle 3180. The handle 3180 is provided on the top 3170 of the carrier body 3100 and facilitates carrying the portable carrier 3000. The handle 3180 can be secured to the top 3170 by sewing. As shown in FIG33 to FIG35 , in some embodiments, the base 3200 includes a first cover 3210 and a second cover 3220. The first cover 3210 and the second cover 3220 can be detachably connected by fasteners, such as screws or bolts. In some embodiments, the first cover 3210 and the second cover 3220 can also be detachably connected by, for example, a snap-fit ​​connection. As shown in FIG34 , in some embodiments, the first cover 3210 and the second cover 3220 together form a storage space 3230. A portion of the reinforcement member 3300 extends into the storage space 3230 and connects to the base 3200. This ensures a smoother bottom wall of the load-bearing space, preventing the reinforcement member 3300 from interfering with objects carried within the load-bearing space, thereby improving the comfort of the load-bearing space. In some embodiments, the storage space 3230 is a recessed groove formed in the lower surface of the base 3200. The portion of the reinforcement member 3300 extending into the storage space 3230 can be completely contained within the storage space 3230 without protruding from the lower surface of the base 3200, thereby allowing the base 3200 to be placed more stably on a vehicle seat or floor. In some embodiments, the base 3200 can have a single-layer structure or a multi-layer structure.As shown in Figures 33 to 35 , in some embodiments, reinforcement members 3300 are provided at least on the front side 3140 and rear side 3160 of the vehicle body 3100. In some embodiments, an inner interlayer is provided on each of the front side 3140 and rear side 3160 to accommodate the reinforcement members 3300. This interlayer can be formed by the inner lining and outer layer materials of the front side 3140 and rear side 3160, respectively. The inner lining and outer layer materials are connected by sewing, gluing, or heat pressing to form an interlayer space. The reinforcement members 3300 are completely enclosed and firmly sandwiched between the inner lining and outer layer materials, providing support while remaining invisible. This ensures that the exterior of the portable vehicle 3000 remains flat and smooth, with no protruding hard parts that would affect the appearance or user experience, while also enhancing the structural stability and user comfort of the portable vehicle 3000. The reinforcement member 3300 includes a first reinforcement member 3310 and a second reinforcement member 3320. As shown in Figures 33 to 35 , the first reinforcement member 3310 is disposed on the rear side 3160 of the carrier body 3100. As shown in Figures 25 and 26 , the shoulder strap assembly 3190 is disposed on the rear side 3160. In other words, the first reinforcement member 3310 is disposed on the same side of the carrier body as the shoulder strap assembly 3190 to support the user's back when carrying the portable carrier 3000. As shown in Figures 33 to 35 , the second reinforcement member 3320 is disposed on the front side 3140 of the carrier body 3100. In other words, the second reinforcement member 3320 is disposed on the other side of the carrier body opposite the shoulder strap assembly 3190. In the embodiment of the second aspect of the present application, the first reinforcement 3310 can serve as a support function, so the "first reinforcement" can also be referred to as a "support member". In addition, the second reinforcement 3320 can also serve as an anti-collision function, so the "second reinforcement" can also be referred to as an "anti-collision member". In some embodiments, as shown in Figures 33 and 34, the second reinforcement 3310 includes a support plate 3311. The support plate 3311 can be integrally injection-molded with the base 3200, or be a separate component, such as a PE board or corrugated board, fixed to the rear side portion 3160 by sewing. This support plate 331L can enhance the support effect of the rear side portion 3160 on the human back, reduce the force when carrying the portable carrier 3000, and improve the comfort when carrying the portable carrier 3000. By adding the support plate 3311 to the rear side portion 3160, the portable carrier 3000 can be prevented from being deformed or collapsed when loaded with heavy objects, thereby maintaining the shape and function of the portable carrier 3000.The support plate 3311 effectively distributes the weight of the portable carrier 3000, evenly distributing pressure across the entire back rather than concentrating it in a single spot. This reduces stress on the shoulders and back, improving comfort during extended carrying. When the support plate 3311 is integrally injection-molded with the base 3200, the entire structure becomes more robust, providing consistent support. This reduces the overall weight of the backpack by eliminating the need for additional fasteners, while also enhancing the durability and waterproofing of the portable carrier 3000. When the support plate 3311 is a separate component (such as PE (polyethylene) board or corrugated board), it is secured to the rear side portion 3160 by sewing. This allows for greater flexibility in the material and thickness of the support plate 3311 to accommodate varying usage requirements. When PE board is used, the support plate 3311 exhibits excellent strength and elasticity, providing support while maintaining a certain degree of flexibility. When corrugated board is used, the support plate 3311 is lightweight and strong, suitable for maintaining the lightweight of the portable carrier 3000 while providing sufficient support. The corrugated board also creates ventilation channels within the rear side portion 3160, enhancing back breathability. In some embodiments, the support plate 3311 can be designed with a curved shape that conforms to the natural curve of the human back to better fit the user's back, providing uniform support and a comfortable experience. The support plate 3311 can be designed to be adjustable, allowing the user to adjust the position or angle of the support plate 3311 based on their back shape and comfort requirements. Shock-absorbing materials or structures, such as elastic cushioning pads or air bags, can be incorporated into the support plate 3311 to provide both support and shock absorption. This can further reduce the impact of prolonged weight bearing on the back and enhance the carrying experience. Ventilation slots or openings in the support plate 3311 can effectively promote air circulation, reduce back sweating, and enhance breathability. As shown in Figures 33 to 35 , the first reinforcement member 3320 includes a reinforcement portion 3322 and a connection portion 3321. The connection portion 3321 connects the ends of the reinforcement portion 3322 and is connected to the base 3200. The reinforcement portion 3322 is supported on the front side 3140 of the vehicle body 3100. The reinforcement portion 3322 and the connection portion 3321 are substantially perpendicular to each other. In some embodiments, the connection portion 3321 is located between the first cover 3210 and the second cover 3220. The connection portion 3321 is secured to the bottom of the first cover 3210 via fasteners to ensure its stability. The connection portion 3321 is also located within the accommodation space 3230.Placing the connection portion 3321 within the accommodation space 3230 not only protects the connection portion 3321 from external influences, effectively securing and securing it, but also further strengthens the connection between the connection portion 3321 and the base 3200. This not only protects against external impacts but also prevents loosening or damage from long-term use. Placing the connection portion 3321 within the accommodation space 3230 prevents loosening or displacement of the connection portion 3321, which could compromise structural strength. Furthermore, it provides additional support and protection for both the first cover 3210 and the second cover 3220, further enhancing the stability of the overall connection. In some embodiments, the fasteners can be screws, bolts, or nails, depending on the strength requirements between the connection portion 3321 and the first cover 3210. Screws are used for removable installation, while nails are suitable for permanent fixtures. During assembly, the connecting portion 3321 is first placed on the bottom of the first cover 3210. Fasteners pass through the connecting portion 3321, securing it to the bottom of the first cover 3210 and firmly fitting it thereto. In some embodiments, the connecting portion 310 extends generally in the front-to-back direction. The reinforcing portion 3322 extends generally parallel to the front side portion 3140, specifically in the up-down direction, extending from the base 3200 toward the top 3170 of the vehicle body 3100. Because the vehicle body 3100 is made of soft fabric, its support strength is relatively low. When the portable vehicle 3000 is subjected to external impact, the vehicle body 3100 is susceptible to deformation, potentially causing damage to objects (e.g., animals) contained within the portable vehicle 3000. In some embodiments, by providing at least a reinforcement portion 3322 on the front side 3140 of the vehicle body 3100, the reinforcement portion 3322 can be more effectively utilized to buffer a significant portion of the impact force, thereby limiting deformation of the vehicle body 3100 and reducing potential damage to items carried within the portable vehicle 3000 caused by external impact forces. In some embodiments, a first reinforcement member 3320 can also be provided on at least one of the left side 3120 or the right side 3130 of the vehicle body 3100 to further enhance the impact resistance of the vehicle body 3100. Referring to Figures 34 and 35 , the second reinforcement member 3320 is an integrally molded component, but is not limited thereto. In some embodiments, the second reinforcement member 3320 is integrally molded, and the connecting portion 3321 is integrally molded with the reinforcement portion 3322. In some embodiments, the second reinforcement member 3320 is made of a hard material, such as a hard alloy (such as stainless steel or aluminum alloy), plastic, or the like.In some embodiments, the second reinforcement member 3320 is formed by bending a rigid tube. In some embodiments, the second reinforcement member 3320 may not be an integrally formed component. Exemplarily, the reinforcement portion 3322 is welded together from multiple components, and the connecting portion 3321 is fixedly connected to the reinforcement portion 3322, or detachably connected to the reinforcement portion 3322, or is at least one component integrally formed with the reinforcement portion 3322. Continuing with Figures 34 and 35, in some embodiments, the reinforcement portion 3322 is in an inverted U-shape, but the shape of the reinforcement portion 3322 is not limited to this. The opening of the inverted U-shaped reinforcement portion 3322 faces the base 3200. There are two connecting portions 3321, each connecting the two ends of the inverted U-shaped reinforcement portion 3322. In some embodiments, the reinforcement portion 3322 may be in an inverted V-shape, an M-shape, a rectangle, or the like. As shown in Figures 25 to 29, in some embodiments, the anchor assembly 3400 includes a connecting assembly 3410 and a locking mechanism 3430. The connection assembly 3410 is used to connect to the connector of a vehicle seat (not shown). Specifically, the connection assembly 3410 is suitable for connection to an ISOFIX interface. In this case, the "connection assembly" may also be referred to as an "ISOFIX connector." The connection assembly 3410 has different states: a locked state, in which it can be locked to the connector (e.g., ISOFIX connector) of the vehicle seat when stationary, and an unlocked state, in which it can be separated from the connector when being carried on the back. When the connection assembly 3410 is not locked to the connector, it remains in the unlocked state. During the process of locking the connection assembly 3410 with the connector, the connection assembly 3410 is driven by the connector to switch to the locked state. The connection assembly 3410 is movably connected to the base 3200, enabling it to switch between an extended position (also referred to as a use position) and a folded position. When the connection assembly 3410 is in the folded position, it is in the unlocked state. As shown in Figures 25 and 26, a locking mechanism 3430 is connected to the connecting assembly 3410. The connecting assembly 3410 has a first locking position and a second locking position. The locking mechanism 3430 is adapted to engage with the different locking positions to lock the connecting assembly 3410 in one of a collapsed position and an expanded position. When the locking mechanism 3430 engages with the first locking position, the connecting assembly 3410 is locked in the collapsed position; when the locking mechanism 3430 engages with the second locking position, the connecting assembly 3410 is locked in the expanded position. There is at least one connecting assembly 3410, and the locking mechanism 3430 is connected to each connecting assembly 3410.As shown in Figures 25 and 26 in conjunction with Figures 36 and 37 , the base 3200 is provided with at least one folding space 3260. When the at least one connecting assembly 3410 is in the folded position (i.e., the anchor assembly 3400 is in the folded state), the at least one connecting assembly 3410 is accommodated within the at least one folding space 3260. When the at least one connecting assembly 3410 is in the deployed position (i.e., the anchor assembly 3400 is in the deployed state (also referred to as the in-use state)), the at least one connecting assembly 3410 can extend from the at least one folding space 3260 to connect with at least one connector of a vehicle seat. Specifically, when the connecting assembly 3410 is in the deployed position, the connecting assembly 3410 and the shoulder strap assembly 3190 extend from the same side of the vehicle body 3100. As shown in Figures 25 and 26 in conjunction with Figures 36 and 37 , in some embodiments, at least one folding space 3260 is formed in the second cover 3220. Therefore, the connecting assembly 3410 is not visible in Figure 36 . In some embodiments, the base 3200 is provided with a single folding space 3260, within which the at least one connecting assembly 3410 is accommodated. Alternatively, the base 3200 is provided with multiple folding spaces 3260, with each connecting assembly 3410 disposed within a corresponding folding space 3260. The base 3200 is also provided with a through-hole connecting the accommodating space 3230 and the at least one folding space 3260, thereby allowing at least a portion of the locking mechanism 3430 to pass through the through-hole and engage with the connecting assembly 3410. The number of through-holes corresponds to the number of connecting assemblies 3410. As shown in Figures 36 and 37, at least two connecting assemblies 3410 are pivotally connected to the rear portion of the base 3200, and at least one folding space 3260 is provided at the rear portion of the base 3200. In some embodiments, the locking mechanism 3430 includes a locking member 3431 and an operating member 3432. To facilitate user operation, the operating member 3432 can be located at the front portion of the base 3200. The portion of the base 3200 away from the connecting assemblies 3410 is the front portion of the base 3200. This allows the user to easily operate the operating member 3432 to release the connecting assembly 3410 when the connecting assembly 3410 is connected to the vehicle seat. In some embodiments, the front portion of the base 3200 forms the front side of the base 3200, which forms a continuous transition with the outer side of the front side portion 3140 of the vehicle body 3100. This means that the front side of the base 3200 is at least partially flush with the outer side of the front side portion 3140.The rear portion of the base 3200 forms the rear side of the base 3200. The rear side of the base 3200 forms a continuous transition with the outer side of the rear portion 3160 of the vehicle body 3100, meaning that the rear side of the base 3200 is at least partially flush with the outer side of the rear portion 3160. Referring to Figures 25 and 26, there are two connecting assemblies 3410, each pivotally connected to the rear side of the base 3200. There are two folding spaces 3260, spaced apart in the left-right direction. In some embodiments, the folding spaces 3260 are grooves recessed into the rear side of the base 3200, with openings extending through the bottom wall of the folding spaces 3260. When the two connecting assemblies 3410 are in the folded position, they are stored in corresponding folding spaces 3260. For example, the outer side of the folded connecting assembly 3410 is flush with the outer side of the base 3200. In some embodiments, the anchor assembly 3400 may include more than two connecting assemblies 3410, and the number of folding spaces 3260 may also be two or more. The two or more connecting assemblies 3410 can be connected to two or more connectors on the vehicle seat. As shown in Figures 25 and 26, the two connecting assemblies 3410 rotate in opposite directions to rotate from the folded position to the deployed position, or vice versa. The rotation axes of the two connecting assemblies 3410 relative to the base 3200 may be parallel. In some embodiments, the two connecting assemblies 3410 can rotate in the same direction to switch between the deployed position and the folded position. As shown in Figure 36, in some embodiments, the locking member 3431 is movably disposed on the base 3200 and has a locked position and a released position. The operating member 3432 is operably disposed on the base 3200 and connected to the locking member 3431. When the connecting assembly 3410 is in different positions, operating the operating member 3432 causes the connecting assembly 3410 to respond differently. In other words, when the operating member 3432 is operated, the connecting assembly 3410 responds differently depending on the position of the connecting assembly 3410. In some embodiments, when the connecting assembly 3410 is in the folded position, operating the operating member 3432 causes the connecting assembly 3410 to switch from the folded position to the extended position. In other words, the movement of the operating member 3432 causes the locking member 3431 to switch from the locked position to the released position, thereby releasing the locking member 3431 from the connecting assembly 3410. In other words, when the operating member 3432 is operated, the connecting assembly 3410 switches from the folded position to the extended position corresponding to the folded position of the connecting assembly 3410.When the connecting assembly is in the deployed position, operating the operating member 3432 causes the connecting assembly 3410 to switch from the locked state to the unlocked state, or remain in the unlocked state, while the connecting assembly remains in the deployed position. In other words, when the operating member 3432 is operated, corresponding to the connecting assembly 3410 being in the deployed position, the connecting assembly 3410 switches from the locked state to the unlocked state, or remains in the unlocked state. As shown in FIG36 , in some embodiments, a locking member 3431 is slidably disposed on the base 3200 and moves relative to the base 3200 between a locked position and a released position. The movement direction of the locking member 3431 is generally parallel to the front-to-back direction. As shown in FIG35 and FIG36 , the connecting assembly 3410 rotates relative to the base 3200 about the rotation axis X. As shown in FIG37 , in some embodiments, the locking member 3431 is provided with a locking protrusion 34311, and the first locking position is a locking recess 34111 provided on the connecting assembly 3410. The locking protrusion 34311 is adapted to engage with the locking recess 34111. Specifically, the locking protrusion 34311 is adapted to pass through the through-door 204 and engage with the locking recess 34111, thereby locking the connecting assembly 3410 in the folded position. As shown in Figures 36 and 37, in some embodiments, the locking mechanism 3430 further includes a linkage member 3434 and a first pulling member 3435. The operating member 3432 is connected to the locking member 3431 via the linkage member 3434 and the first pulling member 3435. In some embodiments, the operating member 3432 is connected to the locking member 3431 via another driving mechanism, or the operating member 3432 and the locking member 3431 are directly connected. Continuing with Figures 36 and 37 , the operating member 3432 is movably disposed on the front portion of the base 3200, and the linkage member 3434 is movably connected to the base 3200. The linkage member 3434 is movably connected to the operating member 3432 and connected to the locking member 3431 via a first pulling member 3435. When the operating member 3432 moves relative to the base 3200, the linkage member 3434 moves. The linkage member 3434, via the first pulling member 3435, drives the locking member 3431 from a locked position to a released position. In some embodiments, the linkage member 3434 is pivotally connected to the base 3200. When the operating member 3432 is operated, the linkage member 3434 rotates. As shown in Figures 29 , 34 , 36 , and 37 , the operating member 3432 is movable between a driven position and an initial position. The movement direction of the operating member 3432 is generally parallel to the front-to-back direction.As the operating member 3432 moves from its initial position to its actuated position, it drives the linkage member 3434 to pivot. The linkage member 3434, via the second traction member 3435, drives the locking member 3431 from its locked position to its unlocked position. In some embodiments, the front portion of the base 3200 is provided with an operating port 3221, which communicates with the accommodation space 3230. In some embodiments, the first cover 3220 is provided with an operating recess 3222, which extends through the sidewall of the operating recess 3222, thereby communicating with the accommodation space 3230. The operating member 3432 is inserted into the operating port 3221. The operating member 3432 includes an operating portion 34322 and an operating connection portion 34323. The operating connection portion 34323 is accommodated within the accommodating space 3230 and movably connected to the linkage member 3434. The operating portion 34322 is accommodated within the operating recess 3222 and projects laterally. This allows the operating portion 34322 to be restrained within the operating recess 3222 by the abutment between the sidewalls of the operating recess 3222 and the operating portion 34322, preventing the operating portion 34322 from retracting within the accommodating space 3230, thereby facilitating forward movement of the operating portion 34322. As shown in Figures 36 and 37 , in some embodiments, the locking mechanism 3430 further includes a reset member 3437. One end of the reset member 3437 is connected to the operating member 3432, and the other end is connected to the base 3200. The reset member 3437 provides elastic restoring force to the operating member 3432, allowing the operating member 3432 to return to its initial position when not in use. In some embodiments, the reset member 3437 is, for example, a tension spring. As shown in Figures 36 and 37 , the linkage member 3434 includes a connecting arm 34342, a pulling arm 3434K, and a pivot portion 34343 located between the connecting arm 34342 and the pulling arm 34341. The pivot portion 34343 is pivotally connected to the base 3200. The connecting arm 34342 is movably connected to the operating member 3432, and the pulling arm 34341 is connected to the first pulling member 3435. The connecting arm 34342 extends in a non-parallel direction to the traction arm 34341. In some embodiments, the connecting arm 34342 is substantially perpendicular to the traction arm 34341, and the linkage member 3434 is substantially shaped like a "7." The linkage member 3434 can be, for example, an integrally molded component. As shown in Figures 36 and 37, in some embodiments, the first traction member 3435 is, for example, a bendable wire such as steel wire or carbon fiber wire.Continuing with Figures 36 and 37, in some embodiments, the locking mechanism 3430 further includes a second pulling member 3438, and the connecting assembly 3410 is connected to the operating member 3432 via the second pulling member 3438. In some embodiments, the second pulling member 3438 is connected at both ends to the linkage member 3434 and the connecting assembly 3410, respectively, and the operating member 3432 is connected to the linkage member 3434. When the connecting assembly 3410 is in the locked state and in the extended position, the operating member 3432 can drive the connecting assembly 3410 from the locked state to the unlocked state via the second pulling member 3438. In some embodiments, when the connecting assembly 3410 is in the locked state, the operating member 3432 moves relative to the base 3200, driving the linkage member 3434 to rotate. The linkage member 3434 then drives the second pulling member 3438 to move as a whole, thereby switching the connecting assembly 3410 from the locked state to the unlocked state. When the connecting assembly 3410 switches to the unlocked state, because the second pulling member 3438 is in a relaxed state, even if the operating member 3432 moves relative to the base 3200 and drives the linkage member 3434 to rotate, the linkage member 3434 cannot drive the second pulling member 3438 to move as a whole, or can only drive the second pulling member 3438 to move as a whole very slightly, causing the connecting assembly 3410 to remain in the unlocked state. In other words, when the connecting assembly 3410 is in the unlocked state, pulling the operating member 3432 does not switch the connecting assembly 3410 between the unlocked and locked states via the first pulling member 3438. In some embodiments, when the connecting assembly 3410 is in the unlocked state, if the connecting assembly 3410 is in the collapsed position and the operating member 3432 is operated, the first pulling member 4351 can drive the locking member 3431 to move toward the unlocked position. Under the action of the return member 440, the connecting assembly 3410 automatically rotates to the expanded position and remains in the unlocked state. As shown in Figures 36 and 37 , one end of the second pulling member 3438 is connected to the linkage member 3434, and the other end is connected to the connecting assembly 3410. The second pulling member 3438 may be, for example, a flexible wire such as a steel wire or a carbon fiber wire. As shown in Figure 37 , in some embodiments, the connecting assembly 3410 includes a housing 3411 and a release member 3414. The housing 3411 is movably disposed on the base 3200. The release member 3414 is movably disposed within the inner cavity of the housing 3411. One end of the housing 3411 is pivotally connected to the rear portion of the base 3200 and forms a pivotal end. The rotation axis of the housing 3411 serves as the rotation axis of the connecting assembly 3410.The other end of the housing 3411 serves as a free end, and the connecting assembly 3410 can be folded and unfolded by rotation. As shown in FIG37 , the release member 3414 is connected to the second pulling member 3438, so that the first pulling member 3438 drives the release member 3414 to move or rotate. In some embodiments, the release member 3414 is slidably disposed within the housing 3411 between a first position and a second position. When the two connecting assemblies 3410 are in the folded position, the two connecting assemblies 3410 are in an unlocked state. Each connecting assembly 3410 is accommodated within the corresponding folding space 3260, each locking member 3431 is in a locked position, engaging with the locking recess 34111 of the corresponding connecting assembly 3410, and each release member 3414 is retained in the second position. When the release member 3414 is in the second position, the second pulling member 3438 is in a relaxed state. To connect the connection assembly 3410 to a connector (e.g., an ISOFIX receptacle on a vehicle seat), the connection assembly 3410 is first deployed. The operating member 3432 is then pulled forward, causing the two linkage members 3434 to rotate horizontally in opposite directions. Each linkage member 3434, through its corresponding first traction member 4351, drives the corresponding locking member 3431 from the locked position to the unlocked position, thereby causing the connection assembly 3410 to spring from the folded position to the deployed position under the action of a reset member (e.g., a torsion spring). During the springing process, the connection assembly 3410 remains unlocked. The seat connector is then connected to the connection assembly 3410. The release member 3414, under the action of the release reset member and pushed by the connector's latch, moves from the first position to the second position. When the release member 3414 reaches the first position, it is locked. To fold the connecting assembly 3410, first separate the connecting assembly 3410 from the connector. Pulling the operating member 3432 forward causes the two linkage members 3434 to rotate horizontally in opposite directions. Each linkage member 3434, via its corresponding second pulling member 3438, drives the corresponding release member 3414 of the connecting assembly 3410 from the first position to the second position. During this process, the release member 3414 automatically rotates from the locked position to the unlocked position. When the release member 3414 rotates to the unlocked position (i.e., the connecting assembly 3410 is unlocked and separated from the connector), the operating member 3432 is released. The reset member 3437 automatically returns the operating member 3432 to its initial position, driving the linkage members 3434 to rotate in the opposite direction to reset the connector. At this point, the release member 3414 is retained in the second position.After separating the connecting assembly 3410 from the connector, the two connecting assemblies 3410 are rotated in opposite directions toward the folded position. The locking protrusion 34311 of the locking member 3431 abuts against the outer surface of the housing 3411 (i.e., the outer surface of the ISOFIX connecting assembly). When the connecting assembly 3410 is rotated to the folded position, the locking protrusion 34311 is no longer abutted by the outer surface of the housing 3411 and faces the locking recess 34111. The locking member 3431 moves to the locked position, engaging the locking protrusion 34311 with the locking recess 34111, thereby locking the connecting assembly 3410 in the folded position. When carrying the portable carrier 3000, the connecting assembly 3410 below the rear portion 3160 of the portable carrier 3000 is concealed and folded, without interfering with the use of the portable carrier 3000 or affecting the normal position or function of the shoulder strap assembly 3190. The folding connection assembly 3410 prevents it from contacting the user's body when carrying the portable carrier 3000, ensuring that the portable carrier 3000 fits snugly and does not cause any discomfort or hinder movement. The second reinforcement member 3310 is located on the rear side 3160 of the portable carrier 3000, directly adjacent to the user's back. The first reinforcement member 3310 provides overall support for the portable carrier 3000 when the user is carrying it, ensuring that the portable carrier 3000 conforms to the user's back and maintains a good shape. The second reinforcement member 3320 supports the front side 3140 and bottom 3150 of the portable carrier 3000, ensuring that the portable carrier 3000 maintains its shape and does not deform or collapse when carrying a pet. The second reinforcement 3320 helps maintain the structure of the portable carrier 3000 when carried, making the pet more stable inside the portable carrier 3000 and preventing the portable carrier 3000's center of gravity from shifting, which could affect the carrying balance. When the user needs to secure the portable carrier 3000 to a vehicle seat (for example, using an ISOFIX receptacle), the operating member 3432 and the connecting assembly 3410 make this process easier and safer. When placing the portable carrier 3000 on the vehicle seat, the user uses the operating member 3432 to actuate the connecting assembly 3410 to its deployed position. The operating member 3432 is located on the front side 3140 of the portable carrier 3000. By pulling the operating member forward, the connecting assembly 3410 on the rear side 3160 of the portable carrier 3000 is ejected from its hidden and folded position to its deployed position. Once ejected, the connecting assembly 3410 engages the ISOFIX receptacle on the vehicle seat.This process is similar to installing a child seat on a vehicle seat, ensuring that the portable carrier 3000 is securely fixed within the vehicle and prevents movement while driving. Once the connecting assembly 3410 is inserted into the ISOFIX socket, it automatically locks, ensuring that the portable carrier 3000 remains stable while the vehicle is in motion and prevents any movement or shaking. To move the portable carrier 3000, the user pulls the operating member 410 forward again, releasing the connecting assembly 3410 from the ISOFIX socket, allowing for easy removal of the portable carrier 3000. When the portable carrier 3000 is secured to the vehicle seat, the first support member 310 and the second reinforcement member 3320 provide structural support for the portable carrier 3000, preventing it from bending or deformation due to load or external forces. The second reinforcement member 3320 is located on the front side 3140, away from the seat backrest. Its high mechanical strength ensures the portable carrier 3000's anti-collision safety during driving, significantly enhancing the safety of the pet inside. At the bottom and front sides of the portable carrier 3000, the second reinforcement member 3320 also reinforces the bottom strength of the portable carrier 3000, helping to maintain its overall shape, particularly when carrying a pet. In some embodiments, the connecting assembly 3410 and the shoulder strap assembly 3190 of the anchor assembly 3400 extend from the same side of the carrier body 3100, for example, from the rear side 3160 of the carrier body 3100. This makes the overall design of the portable carrier 3000 more harmonious, aesthetically pleasing, and safer. When the portable carrier 3000 is placed on a vehicle seat, the connecting assembly 3410 is in the deployed position, extending from the rear portion 3160 of the carrier body 3100 for attachment to the seat. At this point, the shoulder strap assembly 3190 is positioned between the carrier body 3100 and the seat backrest, creating a neater and more aesthetically pleasing structure. The flexible structure of the shoulder strap assembly 3190 and the first reinforcement member 3310 on the rear portion 3160 together provide cushioning and support for the carrier body 3100. When the portable carrier 3000 is carried using the shoulder straps, the connecting assembly 3410 can be folded to the collapsed position, ensuring ease of carrying while maintaining exposure to the front window 3141 on the front portion 3140 for optimal ventilation.Therefore, whether the portable carrier 3000 is fixed to a seat in a transportation vehicle or carried on a user's back, the first reinforcement 3310 is always located on the side closest to the user's back or the seat's backrest, providing support. The first reinforcement 3320 can always be located away from the user's back or the seat's backrest, thereby providing structural strength and enhancing collision protection for the carrier body 3100. In this aspect, the portable carrier 3000 is highly practical in both carrying and placing the carrier. The operating element provides simple controls, making the portable carrier 3000 easier and quicker to attach and detach, making it suitable for use in vehicles. The foldable and deployable connection assembly does not affect the carrying process, maintaining the compact structure of the backpack. The first and second reinforcements play a key role in providing structural support, enhancing comfort, maintaining the portable carrier 3000's shape, and ensuring stability when attached. Whether used for daily use or secured in a vehicle, the user enjoys a stable, safe, and comfortable experience.
