[0252] Detailed Description of Guide Components 34330A, 34330B, and 34340 The technical concepts and implications of this disclosure are illustrated below with reference to the accompanying drawings and exemplary embodiments. In the drawings or description, the same or similar parts are represented by the same or corresponding component symbols; furthermore, the drawings are drawn for ease of understanding, and the dimensions and shapes of the components in the drawings are not the actual dimensions or proportions of the components. Furthermore, the following description of the drawings and embodiments does not imply limiting the scope of this disclosure to a single embodiment; other implementations are possible by replacing some or all of the described or shown components. Moreover, where some components of the disclosed embodiments may use some or all of known components, in some cases, only the portions of such known components necessary for understanding the implementation of this disclosure are described, and detailed descriptions of other portions of these known components are omitted to avoid obscuring the concepts and implementations of this disclosure. In a first aspect of this disclosure, a carrier 1100 with an integrated fixing device is provided for securing the carrier 1100 to a vehicle seat. Please refer to Figures 1A to 1E, which schematically illustrate a carrier 1100 with an integrated fixing device according to an embodiment of the first aspect of this disclosure; wherein Figure 1A is a perspective view of the carrier 1100 of this embodiment, Figure 1B is a bottom perspective view of the carrier 1100, Figure 1C is an enlarged view of the area 1100A enclosed by the dashed line in Figure 1B, and Figures 1D and 1E are bottom perspective views of variations of the aforementioned embodiment. As shown in Figure 1A, the carrier 1100 of this embodiment mainly includes a housing 1110, a handle 1120, and a fixing device 1130 (also referred to as the "first fixing device"). The box 1110 is a box-shaped structure with raised perimeter walls to enclose and define a carrying space S1, which can carry infants or animals (or pets); the box 1110 has two opposing long sides 1110A and 1110B, wherein the long side 1110A is the side of the box 1110 that abuts against the back of a vehicle seat (e.g., a rear seat). The handle 1120 is generally U-shaped and is connected to the housing 1110 in a movable or detachable manner, so that users (such as infant caregivers or animal owners) can easily pick up and carry the carrier 1100 of this embodiment. In this embodiment, the handle 1120 is pivotally connected to the two long sides of the housing 1110 at both ends; that is, the handle 1120 can be rotated at both ends along the pivots 1121 and 1122 toward the upper edge of the peripheral wall of the housing 1110 so as to be stacked on it for easy storage.Alternatively, in other embodiments, the handle 1120 can also be detached from the housing 1110. Alternatively, in other embodiments, the pivot of the handle 1120 can also be located on the outer surfaces of both sides of the housing 1110, rather than on the upper edges of the two long sides of the housing 1110, to reduce the chance of the handle 1120 and its pivot colliding with the animal inside the housing 1110, and to prevent the animal from colliding with the handle 1120 due to changes in vehicle speed during driving, thereby being frightened or injured. In this embodiment, the vehicle 1100 is fixed to the vehicle seat by the fixing device 1130. Referring to FIG1B, the vehicle 1100 of this embodiment has a fixing device 1130 attached to the housing 1110, that is, the fixing device 1130 is directly disposed (e.g., embedded) in the bottom of the housing 1110. Specifically, in this embodiment, the fixing device 1130 may be, for example, a rigid ISOFIX system, which includes a main frame 1131, a connecting frame 1132, connectors 1133 and 1134 (e.g., ISOFIX connectors), and a pull strap 1135. The main frame 1131 is directly fixed to the bottom of the housing 1110, for example, but not limited to, fixing methods such as fitting, locking, or welding. The connecting frame 1132 is U-shaped and consists of a pair of longitudinal connecting brackets 1132K 11322 and a crossbar 11323 connecting the longitudinal connecting brackets 1132K 11322. The ends (or "rear ends") of the two longitudinal connecting brackets 11321 and 11322 are movably connected to the main frame 1131 in a sleeve manner, for example, so that the connecting frame 1132 can telescopically move relative to the main frame 1131, thereby allowing the connectors 1133 and 1134 located at the front end of the connecting frame 1132 to move between the bottom of the housing 1110 and the position protruding from the long side 1110A of the housing 1110. A pull strap 1135 is connected to the crossbar 11323 of the "U-shaped" connecting frame 1132, allowing a user (e.g., a caregiver for infants or an animal owner) to pull it, thus moving the connecting frame 1132 relative to the main frame 1131. Connectors 1133 and 1134 are used to connect to corresponding fixing systems at the vehicle seat, such as ISOFIX anchor points, thereby stably securing the vehicle 1100 of this embodiment to the vehicle seat. Alternatively, in another embodiment, the fixing device 1110 of the vehicle 1100 does not include the pull strap 1135, and the user can adjust the position of connectors 1133 and 1134 by directly pulling them.It should be noted that the "longitudinal" and "horizontal" of the "longitudinal connecting bracket" and "crossbar" mentioned here correspond to the relative directions of the vehicle, which is convenient for distinguishing some parts and / or components. That is, the "longitudinal connecting bracket" and "crossbar" can also be called the "first connecting bracket" and the "second connecting bracket". In this embodiment, as shown in FIG1B, the bottom of the box 1110 of the vehicle 1100 is provided with bottom plate openings 11101 and 11102 (also called "bottom openings") that penetrate the bottom, so that the fixing straps (not shown) of the vehicle 1100 can pass through and fix infants or animals in the carrying space S1 of the vehicle 1100 (which will be further explained in FIG10A and FIG10B, and FIG11A and FIG11B). Additionally, a positioning buckle is provided on the short side 1110C of the housing 1110, away from the openings 11101 and 11102 on the bottom plate, for the free end (not shown) of the fixing strap to pass through, and an adjustment end is formed there for the user to adjust the tightness of the fixing strap. More specifically, as shown in FIG1B, in this embodiment, the fixing device 1130 of the carrier 1100 also includes a release handle 1136, which is also directly provided at the bottom of the housing 1110 of the carrier 1100. When the release handle 1136 is pulled, the locking pins 1136A and 1136B can disengage from the locking holes (e.g., locking hole 11322A) on the main frame 1131 and from one of the corresponding locking holes on the connector 11322. The user can then pull the strap 1135 to stretch the connecting frame 1132 outward relative to the main frame 1131 towards the housing 1110. After the stretching adjustment is completed, releasing the adjustment handle 1136 will reset the locking pins 1136A and 1136B to their corresponding locking holes in the main frame and connecting frame, preventing further movement of the connecting frame 1132. Similarly, after pulling the release handle 1136 to disengage the locking pins 1136A and 1136B from the locking holes, the connecting frame 1132 can be pushed to retract, so that the connectors 1133 and 1134 disengage from the rear seat fixing point after release (as described below).Furthermore, as shown in Figure 1C, the fixing device 1130 of the vehicle 1100 in this embodiment also includes a release device, which is also directly installed at the bottom of the housing 1110 of the vehicle 1100, and is composed of a release mechanism 1137 connected to release linkage steel wires 1138A and 1138B; one end of each of the release linkage steel wires 1138A and 1138B is connected to the release mechanism 1137, and the other end of each is connected to the respective locking blocks (not shown in the figure) of connectors 1133 and 1134. When the user presses the release mechanism 1137, the locking blocks can be driven to disengage from the ISOFIX fixing points at the vehicle seat through the release linkage steel wires 1138A and 1138B, thereby releasing connectors 1133 and 1134, so that the vehicle 1100 of this embodiment can be disengaged from the ISOFIX fixing points at the vehicle seat for unloading. According to this embodiment, the fixing device 1130 of the carrier 1100 is directly fixed or embedded in the bottom of the housing 1110. Therefore, there is no need to use a separate fixing base or a base with supporting feet. The housing 1110 of the carrier 1100 can be directly and stably fixed to the vehicle seat to complete the stable installation of the carrier 1100 in the vehicle. Please refer to Figures 1D and 1E, which illustrate a variation of the aforementioned embodiment. As shown in the figures, the positioning buckle 11103 of the carrier 1100 can be provided on the bottom of the housing 1110, on the short side 1110D near the bottom openings 11101 and 11102. In this embodiment, the two ends of the Y-shaped fixing strap pass through the bottom plate openings 11101 and 11102 and are exposed in the carrying space of the box 1110 for fixing infants and animals (to be further explained in Figures 10A and 10B, and Figures 11A and 11B). The strap body (also called the fixing strip) 11106 of the Y-shaped fixing strap extends through the guide structure 11105 provided at the short side 1110C to change its extension direction, extending towards the short side 1110D and further passing through the positioning buckle 11103 provided at the short side 1110D, forming an adjustment end 11106A, for the user to adjust the tightness of the fixing strap. In this embodiment, since the short side 1110D is the side closer to the head of the infant or animal, and also the side closer to the caregiver in the back seat, the vehicle 1100 of this embodiment can help the caregiver adjust the tightness of the fixing straps according to the actual situation during the journey, so as to avoid excessive pressure on the infant or animal in the carrying space from the fixing straps.According to this embodiment, the box 1110 can be made of a suitable material as needed, including, but not limited to, plastic, wood, metal, or any material with a certain rigidity to provide support. It may also include, but not limited to, cushioning materials or foamed materials, such as expanded polypropylene (EPP) or expanded polystyrene (EPS). Preferably, the box 1110 may be made of rigid plastic. Please refer to Figures 2A and 2B, which schematically illustrate a carrier 1200 with an integrated fixing device according to another embodiment of the first aspect of this disclosure; wherein Figure 2A is a perspective view of the carrier 1200 of this embodiment, and Figure 2B is a bottom perspective view of the carrier 1200. The carrier 1200 shown in Figure 2A has a similar structure and composition to the carrier 1100 of the aforementioned embodiment, including a box 1210, a handle 1220, and a fixing device 1230. The box 1210 is a box-shaped structure with raised peripheral walls to enclose and define a carrying space S1. The handle 1220 is generally U-shaped and is connected to the housing 1210 in a movable or detachable manner, so that users (such as caregivers of infants or pet owners) can easily pick up and carry the carrier 1200 of this embodiment. In this embodiment, the handle 1220 is pivotally connected at both ends to the upper or outer sides of the two long sides of the housing 1210; that is, the handle 1220 can be rotated at both ends along the pivot 122K 1222 towards the upper edge of the housing 1210 peripheral wall so as to be stacked on it for easy storage. The fixing device 1230 can be, for example, a rigid ISOFIX system, which includes a main frame, a connecting frame, connectors 1233 and 1234, and a pull strap 1235. In this embodiment, the fixing device 1230 is also directly disposed at the bottom of the housing 1210, for example, by fitting, locking, or welding its main frame to the bottom of the housing 1210. In this embodiment, the structure of the main frame and connecting frame of the fixing device 1230 is the same as that of the main frame 1131 and connecting frame 1132 in the previous embodiment, that is, the integrated fixing device of the vehicle 1200 is formed by fixing the housing 1210 with the main frame. In this embodiment, the fixing device 1230 also includes structures such as a release handle 1236 and a release device (not shown in the figure). The vehicle 1200 of this embodiment can be further fixed to the rear seat of the vehicle using the rear seat belt by means of its structural design.In detail, in this embodiment, at least one guide (guide 1211, 1212 in this embodiment) is provided on the periphery of the casing 1210 of the vehicle 1200 (e.g., on the periphery of the short side 1210C), and a guide 1223 is also provided on the handle 1220±. The width and size of the guide are designed to allow the rear seat belt of the vehicle to pass through and be positioned therein. Generally, the rear seat belt of a vehicle includes an abdominal belt (or lap belt) extending through the passenger's abdomen and a shoulder strap extending downward from the passenger's shoulder. The shoulder strap and the abdominal belt are connected to a male buckle (e.g., a tab), and the tab is inserted into the corresponding female buckle at the rear seat to fasten. As shown in the figure, in this embodiment, in addition to being fixed to the corresponding ISOFIX fixing point of the vehicle rear seat by the fixing device 1230, when the vehicle 1200 is installed on the vehicle rear seat, the seat belt belly belt (or waist belt) 115A of the vehicle rear seat can also be used to pass through the guide located on the periphery of the short side 1210C of the box 1210.

[0253] 1211, 1212, and the seat belt shoulder strap 115B is fastened by the guide 1223 of the handle 1220 ±, and by the tongue 116 connected thereto, inserted into the corresponding female buckle (not shown) at the rear seat. Thus, the combination of the vehicle's rear seat seat belt with the housing 1210 and the handle 1220 provides a stable and secure effect for the vehicle 1200 of this embodiment. In particular, in this embodiment, the guide 1223 on the handle 1220 limits the seat belt shoulder strap 115B to the handle 1220 ±, which facilitates the seat belt shoulder strap 115B conforming to a portion of the handle 1220 and extending along it. Therefore, the handle 1220 can also provide auxiliary support for the seat belt shoulder strap 115B, preventing the shoulder strap 115B from moving freely during vehicle movement. According to this embodiment, the fixing device 1230 of the vehicle 1200 is directly fixed or embedded in the bottom of the box 1210, and the guides 121K 1212 and 1223 are also directly formed (or set) in the box 1210 and the handle 1220 ± combined with the vehicle rear seat seat belt for fixing. Therefore, there is no need to use a separate fixing base or a fixing base with support feet. The box 1210 can be directly fixed to the vehicle rear seat to complete the stable installation of the vehicle 1200 in the vehicle. In one embodiment, the vehicle 1200 of this embodiment further includes an extension strap 117 (disposed on the outer surface of the housing); when the vehicle 1200 is large in volume, or when the length of the rear seat belt's belly strap 115A and shoulder strap 115B after passing through the guides 1211 and 1212 of the housing 1210 ± and the guide 1223 of the handle 1220 ± is insufficient to connect to the seat belt buckle under the rear seat, the extension strap 117 can be used to lengthen the length of the rear seat belt. In detail, the extension belt 117 includes an extension strip 117A, the ends of which are respectively connected to a female buckle 117B and a male buckle (e.g., a tongue) 117C; the abdominal belt 115A and shoulder belt 115B of the vehicle rear seat belt, after passing through the guides 1211, 1212 on the housing 1210 and the guide 1223 of the handle 1220 ±, are inserted into the female buckle 117B of the extension belt 117 by means of the tongue 116 connected to them, and are fastened to the extension belt 117. The male buckle 117C (e.g., a tongue) of the extension belt 117 is further inserted into the female buckle of the vehicle seat belt (not shown), thereby using the vehicle rear seat belt to fix the vehicle rear seat, and completing the stable installation of the vehicle 1200 in the vehicle in this embodiment.In one embodiment, as shown in FIG3, the vehicle 1300 has a similar structure and composition to the vehicles 1100 and 1200 in the aforementioned embodiments, including a housing 1310, a handle 320, guides 1311, 1312, 1323, and extension straps 117, extension strips 117A, female buckles 117B, and male buckles 117C, etc. In this embodiment, similar component symbols are used to represent the same functions or components, and the same parts will not be described again to avoid confusion of the inventive concept. The difference between this embodiment and the vehicle 1200 shown in FIG2A and FIG2B is that, in this embodiment, the vehicle 1300 does not have an ISOFIX fixing device 1230, but is directly fixed to the rear seat of the vehicle by the rear seat belt; in this embodiment, the fixed installation of the vehicle 1300 in the vehicle can be completed by using the vehicle's rear seat belt to fix the rear seat of the vehicle. Please refer to Figures 4A to 4C, which schematically illustrate a carrier 1400 with an integrated fixing device according to an embodiment of the first aspect of this disclosure; wherein Figure 4A is a perspective view of the carrier 1400 of this embodiment, Figure 4B is a bottom perspective view of the carrier 1400, and Figure 4C is also a bottom perspective view of the carrier 1400. The figures show the structure and components of the fixing device 1430 of the carrier 1400 after removing the bottom cover 1410C of the housing 1410. The carrier 1400 shown in Figures 4A to 4C has a similar structure and composition to the carriers 1100 and 1200 in the aforementioned embodiments, including a housing 1410, a handle 1420, and a fixing device 1430. The housing 1410 is a box-shaped structure with raised peripheral walls to enclose and define a load-bearing space S1. The handle 1420 includes pivots 1421 and 1422. The fixing device 1430 includes a main frame 431, longitudinal connecting brackets 14321 and 14322 connecting the frame, connectors 1433 and 1434, a crossbar 14323, a pull strap 1435, a release handle 1436, locking pins 1436A and 1436B, a release mechanism 1437, and release linkage steel wires 1438A and 1438B, etc. The difference between the vehicle 1400 and the previous embodiment is that, in this embodiment, in addition to the above-mentioned fixing device 1430 as the first fixing device, the vehicle 1400 further includes a second fixing device 1440, which is, for example, a soft ISOFIX system, to provide another fixing point for the vehicle 1400 to the rear seat of the vehicle.In detail, as shown in Figures 4B and 4C, the second fastening device 1440 includes a strap 1441 (e.g., webbing) and a connector 1442 connected to the end of the strap 1441. In this embodiment, the connector 1442 may be, for example, an ISOFIX connector, which can be connected to a corresponding ISOFIX fastening point of the rear seat of the vehicle. The strap 1441 extends at the bottom of the housing 1410 and protrudes from the housing 1410 at the other end (adjustment end) 1441A through an adjuster 1443 located on the long side 1410B of the housing 1410, allowing the user to quickly and easily adjust the length of the strap 1441 of the flexible (soft) connection fastening system 1440. In this embodiment, the adjuster 1443 of the second fixing device 1440 can be selected from any material and length-adjusting buckle existing by those skilled in the art to which this disclosure pertains, such as, but not limited to: adjusting buckle ring, length adjusting buckle, D-ring buckle, slanted buckle, one-way adjusting buckle, cam buckle, etc. In this embodiment, the vehicle 1400 may also include guides correspondingly disposed on the outer surface of the housing 1410 and the handle 1420, i.e., as the guides 1211, 1212 and 1223 in the aforementioned embodiments, so that the seat belt of the vehicle seat (not shown) can pass through and be positioned therein, providing a further stable fixing effect for the vehicle 1400. Please refer to Figures 5A to 5D, which schematically illustrate a carrier 1500 with an integrated fixing device according to an embodiment of the first aspect of this disclosure; wherein Figure 5A is a perspective view of the carrier 1500 of this embodiment, Figure 5B is a bottom perspective view of the carrier 1500, Figure 5C is an enlarged view of the bearing surface in the box bearing space corresponding to the area 1500A enclosed by the dashed line in Figure 5B, and Figure 5D is a schematic diagram of the structure and components of the fixing device 1530 of the carrier 1500 of this embodiment after the bottom cover of the box 1510 is removed.The carrier 1500 shown in Figures 5A to 5D has a similar structure and composition to the carriers 1100, 1200, and 1400 in the aforementioned embodiments, including a housing 1510, a handle 1520, and a fixing device 1530. The housing 1510 is a box-shaped structure with raised peripheral walls to enclose and define a load-bearing space S1; the handle 1520 includes pivots 1521 and 1522; the fixing device 1530 includes a main frame 1531, a connecting frame 1532, longitudinal connecting brackets 15321 and 15322, connectors 1533 and 1534, a crossbar 15323, a pull strap 1535, a release handle 1536, locking pins 1536A and 1536B, a release mechanism, and a release linkage steel wire, etc. The difference between the vehicle 1500 and the previous embodiment is that, in this embodiment, in addition to the aforementioned fixing device 1530, the vehicle 1500 further includes an anchoring device (Top Tether) 1550 to further secure the vehicle 1500 to an anchoring point (not shown) on the rear seat of the vehicle. As shown, the anchoring device 1550 includes a tether 1551, an adjuster 1552, a connecting strap 1553, and a connector 1554, such as a hook. One end of the tether 1551 is connected to and extends through one side of the adjuster 1552, with the end protruding outside the adjuster 1551 to form a tether adjustment end 1551A. The other side of the adjuster 1552 is connected to one end of the connecting strap 1553, and a relatively remote portion of the connecting strap 1553 is connected to the connector 1554 to secure it to a corresponding fixing point (not shown) above the rear seat of the vehicle, or beyond the seat to the rear bottom, as an anchoring point. In this embodiment, the length of the connecting strap 1553 is fixed, while the user can pull the tether adjustment end 1551A that passes through the adjuster 1552 to adjust the length of the tether 1551 in conjunction with the fixing of the adjuster 1552, thereby adjusting the overall length of the anchoring device 1550 to adapt to the position of the fixing point. Alternatively, in other embodiments, the length of the tether 1551 can be fixed, and the user can adjust the length of the connecting strap 1553 using the adjuster 1552, thereby adjusting the overall length of the anchoring device 1550 to adapt to the fixing point of the vehicle's rear seat.As shown in Figure 5C, in this embodiment, one end of the tether 1551 of the anchoring device 1550 passes through the through hole 1510S formed on the bottom outer surface of the housing 1510 and abuts against the inner surface of the housing 1510 through a fastener (e.g., but not limited to: a D-ring) (e.g., fastener 1555) connected to its end. That is, the tether 1551 is engaged with the through hole 1510S by the fastener 1555, thereby fixing it to the housing 1510. The fastener 1555 protrudes from the inner surface of the housing 1510 into the bearing space S1 enclosed by the peripheral wall of the housing 1510. In this embodiment, the vehicle 1500 may also include guides correspondingly disposed on the outer surface of the housing 1510 and the handle 1520, i.e., like the guides 1211, 1212 and 1223 in the aforementioned embodiments, so that the seat belt (not shown) of the vehicle seat or the tether 1551 of the anchoring device 1550 can pass through and be positioned therein, providing further stability and fixation for the vehicle 1500. Please refer to FIG6, which schematically illustrates a vehicle 1600 with an integrated fixing device according to an embodiment of the first aspect of the present disclosure. The vehicle 1600 shown in FIG6 has a similar structure and composition to the vehicle 1500 of the aforementioned embodiments, including the housing 1610, the carrying space S1 defined by the housing 1610, the handle 1620, the pivots 1621 and 1622 of the handle 1620, the fixing device including components such as the connector 1633, and the anchoring device 1650, etc. As shown in the enlarged view in the figure, connector 1633 is an ISOFIX connector with directional connection ends, namely a thicker end 1633A at the top and a relatively thinner end 1633B at the bottom. Connector 1633 also includes a release button 1633C, which the user presses to release connector 1633, allowing it to be detached from the ISOFIX fixing point of the vehicle seat. The difference between vehicle 1600 and the previous embodiment is that, in this embodiment, the fixing device of the vehicle can change its connection direction to be adapted to be fixed to the corresponding fixing point of the left side (i.e., behind the driver's seat) or right side (i.e., behind the passenger seat) of the left vehicle seat. See Figures 7A to 7D for a detailed description below. Referring also to Figures 7A to 7E, which schematically illustrate the detailed structure and operation of the fixing device in vehicle 1600 of the embodiment shown in Figure 6.As shown in Figure 7A, the vehicle 1600 of this embodiment has a fixing device that is attached to the box 1610; that is, the fixing device is directly provided at the bottom of the box 1610, so that the vehicle 1600 of this embodiment can be directly fixed to the rear seat of the vehicle without any additional fixing base or base with supporting feet. In detail, in this embodiment, the fixing device can be, for example, a rigid ISOFIX system, which includes a main frame 1631, a connecting frame (including longitudinal connecting brackets 16321 and 16322, and a crossbar 16323), connectors 1633 and 1634, and a linkage assembly 1670 (including a pull strap 1635). The vehicle 1600 in this embodiment also includes a steering device 1660. The fixing device is connected to the steering device 1660 via the main frame 1631 to pivotally connect to the bottom of the housing 1610. The fixing device can pivot from its original location in the first area to the second area at the bottom of the housing 1610 via the steering device 1660. With the assistance and action of the steering device 1660, the fixing device can change its connection direction to the rear seat of the vehicle to be appropriately fixed to the corresponding fixing point on the left side (i.e., behind the driver's seat) or the right side (i.e., behind the passenger seat) of the rear seat. Referring to Figure 7F, the detailed structure of the steering device in this embodiment is illustrated. In this embodiment, the steering device 1660 includes a pivot 1661, protrusions 1662A and 1662B, and a circular turntable 1663. A circular groove 1616 is formed at the bottom of the housing of the carrier 1600, which accommodates the circular turntable 1663 of the steering device 1660 and serves as the space for the steering device 1660 to operate. The circular turntable 1663 can rotate within it about a rotation center 1663A; in this embodiment, the rotation center 1663A is a central axis coinciding with the center of the circular groove 1616 (not shown) and the center of the circular turntable 1663. The pivot 1661 is fixed in the diametrical direction of the circular turntable 1663 by protrusions 1662A and 1662B (labeled in Figure 7A), thereby rotating with the rotation of the circular turntable 1663. In this embodiment, the pivot 1661 passes through the protrusions 1662A and 1662B, creating a gap between it and the bottom of the housing. This gap also creates a gap between the main frame 1631 connected to the pivot 1661 and the bottom of the housing, preventing it from contacting the outer surface of the bottom of the housing. This gap provides sufficient space for the main frame 1631 to rotate (described below). Alternatively, in other embodiments, a ring-shaped guide rail may be formed at the bottom of the housing 1610.The steering device 1660 includes a pivot and a pair of guide protrusions located outside the pivot and near both ends of the pivot. The guide protrusions engage with an annular guide rail with their outer edges and can move along the annular guide rail, thereby causing the pivot to rotate about the center of the annular guide rail. In this embodiment, one side of the main frame 1631 of the fixing device is connected to the pivot 1661. Since there is a gap between the pivot 1661 and the bottom outer surface of the housing 1610, there is also a gap between the main frame 1631 and the bottom outer surface of the housing 1610, and it does not contact the bottom outer surface of the housing 1610. This allows the main frame 1631 to rotate along the pivot 1661, thereby causing the connecting frame, connectors 1633 and 1634 to flip towards the relatively long side of the housing 1610 (which will be further explained below). In this embodiment, the main frame 1631 of the fixing device is provided with a steering and releasing mechanism. The steering and releasing mechanism includes an operating member 1636, a locking pin 1637, and a return spring 1638 sleeved on the outside of the locking pin 1637. In this embodiment, the locking pin 1637 can engage with the engagement hole (to be further described later) on the inner side of the receiving groove at the bottom of the housing 1610. The main frame 1631 is thus positioned at the bottom of the housing 1610 by engaging the locking pin 1637 with the engagement hole. When the user pulls or pushes the operating member 1636 of the turn release handle in the direction of arrow U shown in the enlarged view of Figure 7A, the locking pin 1637 moves in the same direction, thereby releasing the main frame 1631 and releasing the main frame 1631 from its positioning on the bottom of the box 1610, making it movable. When the user releases the operating member 1636, the locking pin 1637 is reset by the restoring force of the return spring 1638, returning to a state where it can engage with the corresponding engagement hole, thereby positioning the main frame 1631 on the box 1610. In detail, in the state shown in Figure 7A, the vehicle 1600 of this embodiment is fixed to the ISOFIX fixing point of the left vehicle seat (i.e., behind the driver's seat) by connectors 1633 and 1634 provided on its long side 1610A, and can be further fixed to a corresponding fixing point above the rear seat of the vehicle, or beyond the seat to the bottom of the rear seat (not shown in the figure) by the tether 1651, connecting strap and connector (e.g., a hook) 1654 of its anchoring device as an anchoring point.When the user wishes to secure the vehicle 1600 to the right-side vehicle seat as needed, the user first presses the release button 1633C of connector 1633 (as shown in Figure 6) to release connector 1633 (and the release button of connector 1634 (not shown in the figure) to release connector 1634), causing connectors 1633 and 1634 to disengage from the ISOFIX fixing points of the vehicle seat; then, the user pushes or pulls the operating part 1636 of the steering release mechanism to disengage the locking pin 1637 from the engagement hole 1617A (marked in Figure 7B) in the receiving groove 1617, thereby releasing the main frame 1631. Alternatively, the user can pull the adjusting end 1635A of the pull strap 1635 to release the locking linkage assembly 1670 using the pull strap 1635. Furthermore, the main frame 1631 (along with the connecting frame and connectors 1633 and 1634) can be pulled up. The main frame 1631 is flipped along pivot 1661 from its original position in the first region to the vertical plane at the bottom of the housing 1610, so that the main frame 1631 of the fixing device (together with the connecting frame and connectors 1633, 1634) is in an upright state as shown in FIG7C. Specifically, as shown in FIG7B, in this embodiment, the linkage assembly 1670 includes a pair of sliders 1672A, 1672B, a return spring 1671 disposed between sliders 1672A, 1672B, and a pull strap 1635. The pull strap 1635 has a Y-shaped structure, with connecting straps 16351 and 16352 at both ends connecting to sliders 1672A and 1672B respectively. This allows the sliders 1672A and 1672B to move under the pull of the pull strap 1635, compressing the return spring 1671 and moving towards each other. This causes the locking pins 1676A and 1676B of the linkage assembly 1670 to disengage from the engagement holes (not marked) of the longitudinal connecting brackets 16321 and 16322, releasing the longitudinal connecting brackets 16321 and 16322 of the connecting frame. For example, the connecting straps 16351 and 16352 at both ends of the pull strap 1635 can be connected to the corresponding rings 1670A on the sliders 1672A and 1672B by, for example, through a stitching method. The 1670B connection allows the sliders 1672A and 1672B to move when pulled, thereby releasing the locking frame from the bottom of the housing 1610.In this way, the main frame 1631 (together with the connecting frame and connectors 1633 and 1634) can be pulled up, so that the main frame 1631 is flipped along the pivot 1661 from the originally positioned first area to the vertical plane of the bottom of the housing 1610, so that the main frame 1631 of the fixing device (together with the connecting frame and connectors 1633 and 1634) is in the standing state as shown in Figure 7C. Next, the circular turntable 1663 of the steering device 1660 rotates along the central axis 1663A in the circular groove 1616 of the housing 1610 (or moves in the annular guide rail using the guide protrusion), causing the main frame 1631 connected to the steering device 1660 to rotate 180 degrees counterclockwise (as shown by the arrow R in Figure 7C). As the main frame 1631 rotates, the adjustment end 1635A of the pull strap changes from extending from the long side 1610B to extending from the long side 1610A. Finally, the main frame 1631 is flipped again along the pivot 1661 to the parallel plane at the bottom of the housing 1610 and abuts against the second area at the bottom of the housing 1610. The sliders 1672A and 1672B of the linkage assembly 1670 are reset to both sides by the restoring force of the return spring 1671 to push the locking pins 1676A and 1676B into the engagement holes of the longitudinal connecting brackets 16321 and 16322 respectively. The user can then pull the operating part 1636 of the steering release mechanism, and the locking pin 1637 is reset and engaged in the engagement hole 1618A of the receiving groove 1618, so that the fixing device is in the state shown in Figure 7D, so that the vehicle 1600 can be fixed to the vehicle seat through the long side 1610B of the housing 1610. Furthermore, the linkage assembly 1670 also includes a first wall 16701 and a second wall 16702, and the first wall 16701 has two openings 16701A and 16701B. In this embodiment, the first wall 16701 and the second wall 16702 form a track 16703 for stable movement of the sliders 1672A and 1672B within it, and the openings 16701A and 16701B of the first wall 16701 can respectively expose the webbing fixing parts of the sliders 1672A and 1672B, so that the connecting straps 16351 and 16352 can be connected to the sliders 1672A and 1672B respectively through the two webbing fixing parts. Finally, adjust the direction of the tether 1651 of the anchoring device 1650 so that the tether 1651, adjuster 652, connecting strap 653 and connector 1654 extend from the bottom periphery of the housing 1610 toward the long side 1610A, as shown in Figure 7E.In the state shown in Figure 7E, the position of connectors 1633 and 1634 has changed from extending from the long side 1610A to extending from the long side 1610B. In this embodiment, the vehicle 1600 can have connectors 1633 and 1634 on its long side 1610B fixed to the ISOFIX fixing point of the right-side vehicle seat (i.e., behind the passenger seat). Furthermore, it can be fixed to a corresponding fixing point above the rear seat or beyond the seat to the rear bottom (not shown) via the tether 1651, connecting strap 653, and connector 1654 of its anchoring device as an anchoring point. Similarly, by adjusting the adjusting end 1651A of the tether 1651, the length of the tether 1651 of the anchoring device 1650 can be adjusted to suit the vehicle's fixing point position. In this embodiment, the vehicle 1600 may also include guides correspondingly disposed on the outer surface of the housing 1610 and the handle 1620, i.e., like the guides 1211, 1212 and 1223 in the aforementioned embodiments, so that the seat belt (not shown) of the vehicle seat or the tether 1651 of the anchoring device 1650 can pass through and be positioned therein, providing further stability and fixation for the vehicle 1600. Please refer to Figures 8A to 8D, which schematically illustrate a vehicle 1800 with an integrated fixing device according to an embodiment of the first aspect of this disclosure. The vehicle 1800 of this embodiment has a similar structure and composition to the vehicle 1500 of the aforementioned embodiments, including the housing 1810 and the handle 1820. The housing 1810 is a box-shaped structure with raised peripheral walls to enclose and define a carrying space S1. The housing 1810 has two opposing long sides 1810A and 1810B. In the states shown in Figures 8A and 8B, the vehicle 1800 abuts against the back of the rear seat of the vehicle with its long side 1810A. The handle 1820 is generally U-shaped and is connected to the housing 1810 in a movable or detachable manner, allowing users (such as caregivers of infants or pet owners) to easily retrieve and carry the vehicle 1800 of this embodiment. In this embodiment, the handle 1820 is pivotally connected to the two long sides of the housing 1810 at both ends; that is, the handle 1820 can be rotated at both ends along pivots 1821 and 1822 toward the upper edge of the peripheral wall of the housing 1810 to be stacked on top for easy storage. Alternatively, in an alternative embodiment, the handle 1820 can also be detached from the housing 1810. The difference between the carrier 1800 and the previous embodiment is that, as shown in FIG8A, in this embodiment, the anchoring device 1850 of the carrier 1800 is configured as a Y-shaped structure.In detail, the anchoring device 1850 mainly includes a first tether 18511 and a second tether 18512, an adjuster 1852, and a connecting strap 1853. One end of each of the first tether 18511 and the second tether 18512 is connected to the same side of the adjuster 1852, or they are combined (e.g., by sewing) to form the tether 1851 connected to the same side of the adjuster 1852. In this embodiment, one end of the connecting strap 1853 of the anchoring device 1850 extends through the other side of the adjuster 1852, forming an adjusting end 1853A. The opposite end of the adjusting end 1853A of the connecting strap 1853 is connected to a connector (e.g., a hook) 1854 for fixing to a corresponding fixing point (not shown) above the rear seat of the vehicle, or beyond the seat to the rear bottom, as an anchoring point. As shown in Figure 8A, in this embodiment, the U-shaped handle 1820 of the vehicle 1800 is provided with a first guide 1823 and a second guide 1824 on both sides. The width and size of the guides 1823 and 1824 are designed to allow the first tether 18511 or the second tether 18512 of the anchoring device 1850 to pass through and be positioned therein. As shown in the figure, in this embodiment, in addition to being fixed to the corresponding ISOFIX fixing point on the rear seat of the vehicle 1800 by its fixing device (e.g., through the connector 1833 of the fixing device), when the vehicle 1800 is installed on the rear seat of the vehicle, the combination of the tether of the anchoring device 1850 with the housing 1810 and the handle 1820 can further provide a stable fixing effect for the vehicle 1800 in this embodiment. In particular, in this embodiment, the guide 1823 of the handle 1820 ± positions the second tether 18512 of the anchoring device 1850 on the handle 1820, which facilitates the second tether 18512 to conform to a part of the handle 1820 and extend along it. In this way, the handle 1820 can also provide auxiliary support for the anchoring device 1850, preventing the second tether 18512 from moving arbitrarily during vehicle movement. As described above, in this embodiment, the handle 1820 of the vehicle 1800 is pivotally connected at both ends to the two long sides of the housing 1810. The handle 1820 can be rotated at both ends along pivots 1821 and 1822 towards the housing 1810 to the upper edge of the peripheral wall of the housing 1810 to overlap thereon, as shown in FIG8B.In the state shown in Figure 8B, since the handle 1820 is stacked on the upper edge of the periphery of the housing 1810, the guide 1823 on the handle 1820 moves towards the shorter side of the housing 1810 along with the handle 1820, thereby increasing the distance between the contact points of the second tether 18512 and the first tether 18511 with the upper edge of the periphery of the housing 1810. This increased distance allows the supporting force of the anchoring device 1850 on the housing 1810 to be more evenly distributed, which is beneficial to further stabilize the fixation of the vehicle 1800 in the rear seat of the vehicle in this embodiment, and prevents the vehicle 1800 from easily tilting due to vehicle steering or speed changes. Please refer to Figure 8C, which illustrates another difference between the vehicle 1800 in this embodiment and the previous embodiment. As shown in Figure 8C, in this embodiment, the anchoring device 1850 and the connecting frame 1832 of the fixing device of the vehicle 1800 are integrated into one unit. As shown in the figure, the connecting frame 1832 of the fixing device includes two longitudinal connecting brackets 18321 and 18322, and at least one transverse positioning rod (also referred to as a "positioning rod" or "crossbar," similar to the "crossbar" in the previous embodiment; in the embodiment shown in Figure 8C, it is two transverse positioning rods 18323 and 18324) connected between the two longitudinal connecting brackets 18321 and 18322. Connectors (e.g., ISOFIX connectors) 1833 and 1834 are respectively connected to the connecting ends 18321A and 18322A of the connecting brackets 18321 and 18322, thereby fixing them to the corresponding fixing points of the rear seat of the vehicle. The connecting ends 18321B and 18322B of the connecting brackets 18321 and 18322 are respectively integrated with the first tether 18511 and the second tether 18512 of the anchoring device 1850, for example, but not limited to, by means of sewing or nailing. In this embodiment, the transverse positioning rods 18323 and 18324 of the connecting frame 1832 are positioned in the bottom positioning groove of the housing 1810 (described further below), thereby making the anchoring device 1850 and the fixing device integrally integrated with the housing 1810. In this embodiment, the vehicle 1800 may also include guides correspondingly disposed on the outer surface of the housing 1810, such as the guides 1211 and 1212 in the aforementioned embodiment, for the seat belt of the vehicle seat (not shown) to pass through and be positioned therein, providing further stabilization and fixation for the vehicle 1800.It should be noted that in this embodiment, the fixing device and the anchoring device 1850 are integrated as one unit through the connection of the tether and the connecting bracket; alternatively, in other embodiments, the fixing device and the anchoring device 1850 can also be independent devices or components, respectively providing fixing and anchoring functions for the vehicle. Utilizing the fixing device and anchoring device of this embodiment, as well as the positioning groove design at the bottom of the vehicle body, the user can easily change the fixing direction and position of the vehicle 1800 to the rear seat of the vehicle. As shown in Figure 8D, in this embodiment, the integrated fixing device and anchoring device can be disassembled as a whole and fixed to the housing 1810 in opposite directions, forming the state shown in the figure. Specifically, in the state shown in Figure 8D, the vehicle 1800 abuts against the backrest of the rear seat of the vehicle with its long side 1810B, and is anchored to the corresponding fixing points of the rear seat of the vehicle via connectors 1833 and 1834 extending from the long side 1810B, thereby fixing the vehicle 1800 to the right side of the rear seat of the vehicle, i.e., behind the front passenger seat. In this embodiment, in addition to being fixed to the corresponding ISOFIX fixing points of the rear seat of the vehicle by the fixing device (e.g., via its ISOFIX connectors 1833 and 1834), when installed on the rear seat of the vehicle, the vehicle 1800 can also be further stabilized by utilizing the tether of the anchoring device 1850 in conjunction with the housing 1810 and the handle 1820. In particular, in this embodiment, the guide 1824 on the handle 1820 fastens the first tether 18511 of the anchoring device 1850 to the handle 1820, which facilitates the first tether 18511 to conform to a part of the handle 1820 and extend along it. In this way, the handle 1820 can also provide auxiliary support for the anchoring device 1850, preventing the first tether 18511 from moving arbitrarily during vehicle movement. Please refer to Figures 9A to 9C, which schematically illustrate the function and configuration of the connecting frame positioning rod and the bottom positioning groove of the vehicle body in the embodiments shown in Figures 8A to 8D.As shown in the figure, a first positioning structure 1817 and a second positioning structure 1818 are formed at the bottom of the housing 1810, so that the first positioning rod (e.g., the transverse positioning rod 18323) and the second positioning rod (e.g., the transverse positioning rod 18324) of the connecting frame 1832 are respectively positioned therein, thereby allowing the fixing device of this embodiment to be stably connected to the housing 1810. Viewed from the short side of the carrier 1800, the positioning structures 1817 and 1818 each present a T-shaped structure formed by their respective transverse and longitudinal portions. Specifically, the first positioning structure 1817 is formed with a transverse portion 18171 and a longitudinal portion 18172. The longitudinal portion 18172 is connected to the center of the transverse portion 18171 and its width is narrower, thereby forming a left positioning groove 1817A and a right positioning groove 1817B on both sides of the longitudinal portion 18172 at the connection between the transverse portion 18171 and the longitudinal portion 18172. Similarly, the longitudinal portion 18182 of the second positioning structure 1818 is connected to the center of the transverse portion 18181 and has a relatively narrow width, thereby forming a left positioning groove 1818A and a right positioning groove 1818B on both sides of the longitudinal portion 18182 at the connection between the transverse portion 18181 and the longitudinal portion 18182. In this embodiment, the lower edge of the transverse portion 18171 of the first positioning structure 1817 (facing the bottom of the housing 1810) and the lower edge of the transverse portion 18181 of the second positioning structure 1818 (facing the bottom of the housing 1810) form their respective inclined surfaces, namely the left inclined surface 1817A of the first positioning structure 1817. 5 And the right inclined surface 1817B and the left inclined surface 1818A of the second positioning structure 1818 5And the right-side inclined surface 1818B. As shown in Figures 9B and 9C, with this inclined surface design, the connecting frame 1832 can use its positioning rods 18323 and 18324 to slide from the left-side inclined surface 1817A and 1818A respectively into the corresponding left-side positioning grooves 1817A and 1818A and be positioned therein, so that the fixing device of this embodiment can be stably connected to the housing 1810, as shown in Figure 9C. Alternatively, when it is desired to change the fixing position and direction of the vehicle seat of the vehicle 1800 in this embodiment (for example, when it is desired to fix it to the right side of the rear seat of the vehicle, i.e., behind the passenger seat, as shown in Figure 8D), the positioning rods 18323 and 18324 can also slide from the right-side inclined surface 1817B and 1818B respectively into the corresponding right-side positioning grooves 1817B and 1818B and be positioned therein. It should be noted that, although the embodiments shown in Figures 8A to 8D and Figures 9A to 9C are illustrated using the connecting frame 1832 including two transverse positioning rods 18323 and 18324 as examples, in other embodiments, the connecting frame 1832 may include only one transverse positioning rod connected between the two longitudinal connecting brackets 18321 and 18322 near their midpoints, which can then cooperate with the inclined surface 1817B at the bottom of the housing 1810. 5 Or 1818A 5The vehicle 1800 is positioned by sliding into the right positioning groove 1817B and the left positioning groove 1818A, thereby fixing the vehicle 1800 to the rear seat of the vehicle in a selected position and orientation. According to this disclosure, the vehicle with integrated fixing device can be used as a general infant or toddler reclining car seat device, or as a vehicle transport device for transporting animals or pets. Please refer to Figures 10A and 10B, which schematically illustrate a vehicle for accommodating infants or toddlers according to an embodiment of the first aspect of this disclosure, wherein Figure 10A is a front view of the vehicle 11000 of this embodiment, and Figure 10B is a rear view of the vehicle 11000 of this embodiment. In this embodiment, the fixing strap of the carrier 11000 includes a first strap 11071, a second strap 11072, and a main strap 11070 (similar to the "strip body portion 11106" in the previous embodiment, also referred to as "fixing strip") connected to the respective fixing ends of the first strap 11071 and the second strap 11072, thus presenting a Y-shaped structure. The first strap 11071 and the second strap 11072 extend from the bottom of the housing 11010 through the first bottom plate opening 11011 and the second bottom plate opening 11012, respectively, and are connected at one end to their respective fasteners (e.g., tongues or other types of male fasteners) 11071A and 11072A. The first strap 11071 and the second strap 11072 are fastened to the buckles (e.g., seat belt buckles) 11075A on the fixed strap (also referred to as "box strap") 11075 via their respective fasteners 11071A and 11072A, thereby forming a closed fixed structure that provides corresponding fixation and support for the shoulders of infants and young children. As shown in Figure 10B, the first strap 11071 and the second strap 11072 extend on the back of the housing 11010 and are connected together to one end of the main pull strap 11070. The other end (free end) of the main pull strap 11070 extends further through a positioning buckle 11013 located on the short side of the housing 11010, where an adjustment end 11070A is exposed. The user can adjust the tightness of the pull strap by pulling the adjustment end 11070A and by positioning it through the positioning buckle 11013. Please refer to Figures 11A and 11B, which schematically illustrate a vehicle for transporting animals or pets according to an embodiment of the first aspect of this disclosure, wherein Figure 11A is a front view of the vehicle 11100 of this embodiment, and Figure 11B is a rear view of the vehicle 11100 of this embodiment.In this embodiment, the fixing strap of the carrier 11100 includes a first strap 11171 and a first strap 11172 (also referred to as a "back strap"), and a main strap 11170 (similar to the "strap body portion 11106" in the previous embodiment, also referred to as a "fixing strip") connected to the fixing ends of the first strap 11171 and the second strap 11172, thus presenting a Y-shaped structure. The first strap 11171 and the second strap 11172 extend from the first bottom plate opening 11111 and the second bottom plate opening 11112 formed at the bottom of the housing 11110, respectively, and one end of each strap is connected to a fastener (e.g., a tongue or other type of male fastener) 11171A, 11172AB; the first strap 11171 and the second strap 11172 are respectively connected to the fixing strap 11175 through their respective fasteners 11171A, 11172A. The fasteners (e.g., seatbelt buckles) 11175A and 11176A at one end of 11176 engage to form a closed, fixed structure, providing corresponding fixation and support for the animal's shoulders and back. As shown in Figure 11B, the first strap 11171 and the second strap 11172 extend from the back of the enclosure 11110 and connect together to one end of the main pull strap 11170. The other end (free end) of the main pull strap 11170 extends further through a positioning buckle 11113 located on the short side of the enclosure 11110, where an adjustment end 11170A is exposed. The user can adjust the tension of the fixed pull strap by pulling the adjustment end 11170A and by positioning it through the positioning buckle 11113. In one embodiment, the fixing straps in carrier 11000 and carrier moo can be applied to the carriers of the above-described embodiments. This disclosure does not limit the possible combinations of implementations among the above-described carriers. Furthermore, for the carriers of the above-described embodiments, the positioning fasteners on the short side of the housing can be replaced by the guide structure 11105 shown in Figures 1D and 1E, and a positioning fastener 11103 can be provided on the other short side, thereby allowing caregivers to easily adjust the tightness of the fixing straps. Moreover, although the housing shape of the above-described embodiments is a cuboid, this disclosure does not limit the housing shape of the carrier; it can also be a cube, without two long sides and two short sides, but with four sides of approximately equal length. In this disclosure, the terms "integrated fixing device" or "integrated fixing device" mean that the fixing device of the vehicle disclosed herein is directly fixed or embedded in the bottom of the box and combined with the box of the vehicle, so that the vehicle of the present disclosure can directly fix the vehicle seat with the box itself.In summary, the first aspect of this disclosure provides a vehicle with an integrated fixing device, and a corresponding fixing device. According to this disclosure, the fixing device of the vehicle is directly fixed or embedded in the bottom of the housing, thus eliminating the need for a separate fixing base. The housing itself can be directly and stably fixed to the rear seat of the vehicle, completing the secure installation of the vehicle within the vehicle. The first aspect of this disclosure also provides a vehicle with a changeable fixing direction. Through the fixing device of the vehicle of this disclosure, the user can quickly and easily fix the vehicle to the left side (i.e., behind the driver's seat) or right side (i.e., behind the passenger seat) of the rear seat of the vehicle, according to actual application needs. In the second aspect of this disclosure, a vehicle is provided, particularly a pet vehicle. For ease of understanding, similar structures in the following different embodiments are marked with similar labels. For example, the pet carriers in the first to eighth embodiments of the second aspect of this disclosure are marked as "2100" to "2800" respectively. Please refer to Figures 12A to 12G. Figures 12A and 12B are schematic diagrams of the appearance of the pet carrier 2100 of the first embodiment of the second aspect of this disclosure from different perspectives. Figure 12C is a schematic cross-sectional view of the pet carrier 2100 of the first embodiment of the second aspect of this disclosure. Figure 12D is a schematic diagram of the restraint device 2120 of the first embodiment of the second aspect of this disclosure. Figures 12E and 12F are schematic diagrams of the pet carrier 2100 of the first embodiment of the second aspect of this disclosure in different usage states. Figure 12G is a schematic diagram of the pet carrier 2100 of the first embodiment of the second aspect of this disclosure when the handle is closed. As shown in Figures 12A to 12G, the pet carrier 2100 includes a housing 2110 and a restraint device 2120. The housing 2110 includes a bottom 2111 and a peripheral wall 2112 connecting the bottom 2111. The bottom 2111 and the peripheral wall 2112 define a receiving space 2113 for accommodating the pet. The bottom 2111 includes a bottom opening 21111. The restraint device 2120 includes restraint webbing 2121. The restraint webbing 2121 passes through the bottom opening 21111 and is at least partially located within the receiving space 2113. The restraint webbing 2121 can be used to cooperate with a connector provided on a pet vest P0 worn by the pet, thereby confining the pet within the receiving space 2113. The connector can be a retaining ring (e.g., a metal ring, a webbing ring, or a buckle made of other materials capable of withstanding high tensile forces). Furthermore, in this embodiment... The housing 2110 may be generally rectangular in shape, but this disclosure is not limited to this embodiment. In another embodiment, the housing may be generally square in shape.As shown in Figures 12E and 12F, the restraint webbing 2121 can be threaded through the connector P1 on the pet vest P0 near the pet's back or the connector P2 on the pet vest P0 near the pet's chest or abdomen, so that the restraint webbing 2121 and the corresponding connector can cooperate with each other. However, this disclosure is not limited to this embodiment, and the restraint webbing can be threaded through any connector on the pet vest. As shown in Figures 12A to 12D and Figure 12G, the restraint device 2120 further includes a fastener assembly 2122, which includes a first fastener 21221 and a second fastener 21222. Specifically, the first fastener 21221 and the second fastener 21222 can be a male and a female fastener, respectively. The first fastener 21221 is located at the free end 21211 of the restraint webbing 2121, and the second fastener 21222 is located at the bottom 2111 of the housing 2110. The free end 21211 of the restraint webbing 2121 is detachably connected to the bottom 2111 of the housing 2110 through the engagement of the first fastener 21221 and the second fastener 21222. Furthermore, the restraint device 2120 also includes an adjuster 2123, through which the restraint webbing 2121 is threaded. The adjusting end 21212 of the restraint webbing 2121 protrudes outside the adjuster 2123. The adjuster 2123 is used to lock the restraint webbing 2121, thereby preventing the restraint webbing 2121 from moving relative to the adjuster 2123. The adjuster 2123 is also used to release the restraint webbing 2121, thereby allowing the restraint webbing 2121 to move relative to the adjuster 2123, so that the user can pull the free end 21211 or the adjusting end 21212 to adjust the length of the restraint webbing 2121 within the accommodating space 2113 according to actual needs (such as the size of the pet). Specifically, as shown in Figures 12A to 12C, the bottom opening 21111 can penetrate the bottom 2111 of the enclosure 2110, and the adjuster 2123 can be set on the outer surface of the enclosure 2110 and near the long side of the bottom 2111 of the enclosure 2110, so as to facilitate user operation and prevent accidental contact by the pet.The user can first operate the adjuster 2123 (for example, press the button 21231 of the adjuster 2123 to pivot it in the direction of the arrow shown in Figure 12C) to release the restraint webbing 2121. Then, the restraint webbing 2121 is threaded onto the connector P1 near the pet's back on the pet vest P0 or the connector P2 near the pet's chest or abdomen on the pet vest P0, so that the restraint webbing 2121 and the connector P1 or connector P2 cooperate with each other. After the restraint webbing 2121 is threaded onto the connector P1 near the pet's back on the pet vest P0 or the connector P2 near the pet's chest or abdomen on the pet vest P0, the user can fasten the first buckle 21221 onto the second buckle 21222, so that the free end 21211 of the restraint webbing 2121 can be detachably connected to the bottom 2111 of the box body 2110. Then, the user can operate the adjuster 2123. (For example, releasing the pressure button 21231 of the adjuster 2123 causes it to pivot in the opposite direction to the arrow shown in FIG12C) to lock the restraint webbing 2121, thereby achieving the purpose of confining the pet within the accommodating space 2113 and improving the pet's riding safety. Please refer again to FIG12B, FIG12H and FIG121. FIG12H is a schematic diagram of the base B0 used with the pet carrier 2100 of the first embodiment of the second aspect of the present disclosure, and FIG121 is a schematic diagram of the pet carrier 2100 of the first embodiment of the second aspect of the present disclosure installed on the base B0. As shown in FIG12B, FIG12H and FIG121, the pet carrier 2100 also includes at least one engaging component. Specifically, at least one engaging component includes a first engaging component 2130 and a second engaging component 2140. The first engaging component 2130 and the second engaging component 2140 are disposed at the bottom 2111 of the housing 2110 and spaced apart from each other along the long axis of the housing 2110. The pet carrier 2100 can be mounted on the base B0 by engaging one of the first engaging component 2130 and the second engaging component 2140 with the engaging structure B1 of the base B0, thereby allowing the pet carrier 2100 to be mounted on a vehicle seat (not shown in the figure) via the base B0. The base B0 can be mounted on the vehicle seat via a support foot B2 and a fixing device B3 (e.g., an International Standards Organization (ISO) fixing device). In another embodiment, the base can also be mounted on the vehicle seat via a vehicle seat belt.More specifically, the first engaging assembly 2130 includes a first engaging member 2131 and a second engaging member 2132, and the second engaging assembly 2140 includes a third engaging member 2141 and a fourth engaging member 2142. The first engaging member 2131 and the second engaging member 2132 are spaced apart from each other along the minor axis of the housing 2110, and the third engaging member 2141 and the fourth engaging member 2142 are spaced apart from each other along the minor axis of the housing 2110. The first engaging member 2131 and the third engaging member 2141 are aligned with each other along the major axis of the housing 2110, and the second engaging member 2132 and the fourth engaging member 2142 are aligned with each other along the major axis of the housing 2110. The user can selectively engage the first engaging member 2131 and the second engaging member 2132 into the corresponding engaging portions B of the engaging structure B1 according to the installation position. 11. Alternatively, the third locking member 2141 and the fourth locking member 2142 can be respectively engaged with the corresponding engaging portions B1L of the engaging structure B1 to adjust the mounting position of the pet carrier 2100 relative to the base B0. For example, when the pet carrier 2100 is installed behind the driver's seat of a left-hand drive vehicle, the user can choose to engage the first locking member 2131 and the second locking member 2132 with the corresponding engaging portions B1L of the engaging structure B1 to position the pet carrier 2100 relative to the base B0 as shown in Figure 121; when the pet carrier 2100 is installed behind the passenger seat of a left-hand drive vehicle, the user can choose to engage the third locking member 2141 and the fourth locking member 2142 with the corresponding engaging portions B1L of the engaging structure B1 to position the pet carrier 2100 relative to the base B0 in another position. This avoids interference between the enclosure 2110 and the vehicle's doors or other structures, and also prevents the adjuster 2123 from being obstructed and unable to operate properly when the pet carrier 2100 is installed in the vehicle seat. Understandably, in another embodiment, at least one engaging component may include only a first engaging component or a second engaging component. Alternatively, in another embodiment, at least one engaging component may include a first engaging component, a third engaging component disposed between the first engaging component and the second engaging component.Additionally, as shown in Figures 12A, 12B, and 12G, the pet carrier 2100 also includes two structural reinforcements 2150 and a handle 2160. The two structural reinforcements 2150 are spaced apart from each other at the bottom 2111 of the housing 2110. Each structural reinforcement 2150 can be a rib with its long axis direction approximately parallel to the short axis direction of the housing 2110. The structural reinforcements 2150 can enhance the structural strength of the pet carrier 2100 to improve its impact resistance. The two ends of the handle 2160 are pivotally connected to the two long sides of the peripheral wall 2112 of the housing 2110, so that the handle 2160 can be pivotally unfolded relative to the peripheral wall 2112 to facilitate the extraction of the pet carrier 2100 or pivotally folded to facilitate the storage of the pet carrier 2100. In another embodiment, the structural reinforcement can also be a horizontal crossbar extending along the short axis direction of the housing 2110. Furthermore, it is understood that the structure of the pet carrier disclosed herein is not limited to this embodiment. For example, in another embodiment, the pet carrier may include only one structural reinforcement. Alternatively, in another embodiment, at least one of the structural reinforcement and the handle may be omitted. Alternatively, in another embodiment, the handle may be detachable from the peripheral wall. Please refer to Figures 13A to 13D. Figures 13A and 13B are schematic diagrams of the appearance of the pet carrier 2200 of the second embodiment of the second aspect of this disclosure from different perspectives. Figure 13C is a schematic cross-sectional view of the pet carrier 2200 of the second embodiment of the second aspect of this disclosure. Figure 13D is a partial structural schematic diagram of the restraint device 2220 of the second embodiment of the second aspect of this disclosure.As shown in Figures 13A to 13D, the pet carrier 2200 of this embodiment includes a housing 2210 and a restraint device 2220. Unlike the pet carrier 2100 of the first embodiment, the restraint device 2220 of this embodiment includes a retractor 2224 but does not include an adjuster. The bottom 2211 of the housing 2210 includes a chamber 22112 communicating with a bottom opening 22111. The retractor 2224 is housed within the chamber 22112. The adjusting end 22212 of the restraint webbing 2221 is connected to the retractor 2224. The retractor 2224 allows the restraint webbing 2221 to be wound up or extended. That is, the user can extend the length of the restraint webbing 2221 within the accommodating space by pulling it, and can also allow the retractor 2224 to wind up the restraint webbing 2221 by releasing it. Furthermore, the retractor 2224 can also lock the restraint webbing 2221 when it is rapidly pulled and extended, thus preventing the restraint webbing 2221 from extending. The structure of the retractor 2224 is similar to that of a known vehicle seat belt retractor, and will not be described in detail here for simplicity. In addition, the restraint device 2220 also includes a guide 2225, which is located near the retractor 2224 and is used to guide the restraint webbing 2221 towards the turning section 22213 of the retractor 2224. The guide 2225 has an arc surface for contacting the restraint webbing 2221, so that the turning section 22213 of the restraint webbing 2221 has a smooth path, thereby making the retracting or extending operation of the restraint webbing smoother. However, this disclosure is not limited to this embodiment. For example, in another embodiment, the restraint device may not include a guide. Other structures in this embodiment are similar to those in the first embodiment and also have similar variations. For the sake of brevity, they will not be described again here. Please refer to Figures 14A to 14C. Figures 14A and 14B are schematic diagrams of the appearance of the pet carrier 2300 of the third embodiment of the second aspect of this disclosure from different perspectives, and Figure 14C is a schematic cross-sectional view of the pet carrier 2300 of the third embodiment of the second aspect of this disclosure.As shown in Figures 14A to 14C, the pet carrier 2300 of this embodiment includes a housing 2310 and a restraint device 2320. Unlike the pet carrier 2200 of the second embodiment, the bottom 2311 of the housing 2310 in this embodiment includes a main body 23113 and a rotating member 23114 rotatable relative to the main body 23113. The main body 23113 may form a rotating groove 23113A for accommodating the rotating member 23114. The rotating groove 23113A may be provided with a guide rail 23113B for positioning and guiding the rotation of the rotating member 23114. A bottom opening 23111 and a cavity 23112 are formed on the rotating member 23114. The first buckle 23221 and the second buckle 2322 of the buckle assembly 2322 are respectively disposed on the restraint webbing 2321 and the rotating member 23114. When the pet moves within the accommodating space 2313, the restraint webbing 2321 can be stressed, causing the rotating component 23114, the buckle assembly 2322, the retractor 2324, and the guide component 2325 to rotate relative to the main body 23113 in the direction of the arrow shown in Figure 14A, to prevent the restraint webbing 2321 from becoming tangled or knotted. Understandably, in another embodiment, the main body and the rotating component may be rotatably connected to each other via a pivot or via a guide rail and a pivot. Other structural features of this embodiment are similar to those of the second embodiment and also have similar variations; for simplicity, they will not be described further here. Please refer to Figures 15A to 15G. Figures 15A and 15B are schematic diagrams of the appearance of the pet carrier 2400 according to the fourth embodiment of the second aspect of this disclosure from different perspectives. Figure 15C is a schematic cross-sectional view of the pet carrier 2400 according to the fourth embodiment of the second aspect of this disclosure. Figures 15D and 15E are schematic diagrams of part of the internal structure of the pet carrier 2400 according to the fourth embodiment of the second aspect of this disclosure. Figure 15F is a schematic diagram of part of the structure of the restraint device 2420 according to the fourth embodiment of the second aspect of this disclosure. Figure 15G is a schematic diagram of the operating member 24271 according to the fourth embodiment of the second aspect of this disclosure. As shown in Figures 15A to 15G, the pet carrier 2400 of this embodiment includes a housing 2410 and a restraint device 2420. Unlike the pet carrier 2200 of the second embodiment, the restraint device 2420 of this embodiment includes a hook 2426 but does not include a buckle assembly. The hook 2426 is disposed at the free end 24211 of the restraint webbing 2421. The hook 2426 fastens to the connector on the pet vest, thereby enabling the restraint webbing 2421 and the connector on the pet vest to cooperate with each other.Specifically, the hook 2426 includes a connecting portion 24261 and a fastening portion 24262. The connecting portion 24261 connects to the free end 24211 of the restraint webbing 2421, and the fastening portion 24262 is fixedly connected to the connecting portion 24261 and used to fasten the connector on the pet vest. However, this disclosure is not limited to this embodiment. For example, please refer to FIG16, which is a partial structural schematic diagram of the restraint device 2520 according to the fifth embodiment of the second aspect of this disclosure. As shown in FIG16, the fastening portion 25262 of the hook 2526 is rotatably connected to the connecting portion 25261 to prevent the restraint webbing 2521 from tangling and knotting.Furthermore, as shown in Figures 15A to 15G, the restraint device 2420 also includes a locking device 2427. The locking device 2427 is used to lock the retractor 2424 so that the retractor 2424 cannot rotate, thereby preventing the retractor 2424 from winding or releasing the restraint webbing 2421. Specifically, the locking device 2427 includes an operating member 24271, a driving member 24272, an elastic member 24273, a first locking member 24274, two second locking members 24275, and a reset member 24276. The two second locking members 24275 are located on both sides of the retractor 2424 and are coaxially arranged with the retractor 2424. Each second locking member 24275 includes multiple locking notches 24275A. The operating member 24271 is rotatably disposed at the bottom 2411 of the housing 2410 and can pivot between the locked position shown in FIG. 15D and the unlocked position shown in FIG. 15E. The driving member 24272 is slidably disposed at the bottom 2411 of the housing 2410 and includes a first end 24272A and a second end 24272B. The first end 24272A of the driving member 24272 forms a recess 24272C for engaging with the first locking member 24274. The second end 24272B of the driving member 24272 forms a receiving groove 24272D for engaging with the operating member 24271. The bottom 2411 of the housing 2410 has a protrusion 412 passing through the driving member 24272 and located between the first end 24272A and the second end 24272B. An elastic member 24273... The operating member 24271 is located between and abuts the first end 24272A of the driving member 24272 and the protrusion 412. The operating member 24271 includes a cam structure 24271A. The cam structure 24271A is at least partially located in the receiving groove 24272D. The cam structure 24271A can slide against the driving member 24272 when the operating member 24271 rotates. The reset member 24276 is connected to the first locking member 24274 and is used to drive the first locking member 24274 to disengage from the locking notch 24275A.When the operating member 24271 switches from the unlocking position shown in Figure 15E to the locking position shown in Figure 15D, the elastic member 24273 is released, causing the driving member 24272 to move along the first direction D1. This causes the first end 24272A of the driving member 24272 to engage the first locking member 24274 along the first direction D1 with the corresponding locking notch 24275A. Furthermore, when the operating member 24271 switches from the unlocking position shown in Figure 15E to the locking position shown in Figure 15D, the cam structure 24271A only contacts the first sidewall W1 of the receiving groove 24272D and not the second sidewall W2 of the receiving groove 24272D (i.e., a clearance space S2 is formed between the cam structure 24271A and the second sidewall W2 of the receiving groove 24272D to allow the driving member 24272 to move along the second direction D2, opposite to the first direction D1). When the first locking member 24274 engages with the corresponding locking notch 24275A, the retractor 2424 cannot rotate. When the operating member 24271 switches from the locking position shown in FIG15D to the unlocking position shown in FIG15E, the cam structure 24271A of the operating member 24271 pushes against the first sidewall W1 of the receiving groove 24272D to drive the driving member 24272 to move along the second direction D2, so that the clearance space S2 gradually shrinks until the second sidewall W2 of the receiving groove 24272D contacts the cam structure 24271A, thereby elastically compressing the elastic member 24273 and causing the reset member 24276 to drive the first locking member 24274 to disengage from the corresponding locking notch 24275A along the second direction D2 to allow the retractor 2424 to rotate. That is, the pet carrier 2400 of this embodiment allows the user to operate the operating member 24271 of the locking device 2427 to lock the retractor 2424 according to actual needs. To restrict the winding or elongation of the binding webbing 2421, or to operate the operating member 24271 of the locking device 2427 to release the retractor 2424, thereby allowing the binding webbing 2421 to wind up or elongate. However, the structure of the locking device disclosed herein is not limited to this embodiment. For example, in another embodiment, the locking device may not include an elastic member and a reset member, and the operating member is slidably disposed at the bottom of the housing and used to slide to engage or disengage the driving member from the corresponding locking notch. Alternatively, in another embodiment, the locking device may only include a second locking member located on one side of the retractor, and the second locking member includes one or more locking notches.As shown in Figure 15F, in this embodiment, the two ends of the reset member 24276 are respectively connected to the bracket 24241 of the first locking member 24274 and the retractor 24244. A sliding groove 24241A is formed on the side of the bracket 24241 near the second locking member 2475, allowing the corresponding end of the first locking member 24274 to slide through. The long axis of each sliding groove 24241A is parallel to the first direction D1. A rotating member 24242, which can rotate relative to the bracket 24241, is also provided on the side of the bracket 24241. An inclined groove 24242A is formed on the rotating member 24242, and the extending direction of the inclined groove 24242A is inclined relative to the first direction D1. When the binding webbing 2421 is pulled, causing the rotating member 24242 to rotate in the direction indicated by the arrow, the sliding groove 24242A and the sliding groove 24241A pass through the bracket 24242A. The first locking member 24274, in conjunction with A, can move along the first direction D1 to engage the locking notch 24275A, thereby preventing the restraint webbing 2421 from elongating. Other structures in this embodiment are similar to those in the second embodiment and also have similar variations; for simplicity, they will not be described further here. Furthermore, it is understood that in another embodiment, the restraint webbing connected to the hook may also be fitted with an adjuster instead of a retractor. Please refer again to Figures 17A to 17D. Figure 17A is a schematic external view of the pet carrier 2600 according to the sixth embodiment of the second aspect of this disclosure; Figure 17B is a cross-sectional schematic view of the pet carrier 2600 according to the sixth embodiment of the second aspect of this disclosure; and Figures 17C and 17D are schematic diagrams of the stop member 2628 according to the sixth embodiment of the second aspect of this disclosure from different perspectives. As shown in Figures 17A to 17D, the pet carrier 2600 of this embodiment includes a housing 2610 and a restraint device 2620. Unlike the pet carrier 2400 of the fourth embodiment, the hook 2626 of the restraint device 2620 in this embodiment includes a connecting portion 26261 and a fastening portion 26262 for rotating the connecting portion 26261, so as to prevent the restraint webbing 2621 from getting tangled or knotted. That is, the hook 2626 of this embodiment is similar to the hook 2526 of the fifth embodiment. The restraint device 2620 includes a stop 2628, but does not include a locking device. The stop 2628 is provided on the restraint webbing 2621 and is used to abut against the bottom 2611 of the housing 2610, thereby limiting the winding length of the restraint webbing 2621 by the retractor to prevent the length of the restraint webbing 2621 from being too short in the accommodating space.Preferably, the length of the binding webbing 2621 within the accommodating space (i.e., the length of the binding webbing 2621 protruding from the bottom 2611 of the housing 2610) can not exceed the height of the peripheral wall 2612 of the housing 2610 protruding from the bottom 2611 (for example, between 30 and 40 cm, but not limited thereto). Specifically, the stop 2628 can be a H-shaped webbing buckle, and multiple protrusions 26281 are formed on the H-shaped webbing buckle, which can contact the binding webbing 2621 to increase the friction force of the H-shaped webbing buckle acting on the binding webbing 2621, so that the stop 2628 can be positioned at any position on the binding webbing, but the structure of the stop in this disclosure is not limited to this embodiment. For example, please refer to Figures 18A to 19D. Figure 18A is a schematic diagram of the appearance of the pet carrier 2700 according to the seventh embodiment of the second aspect of this disclosure. Figure 18B is a schematic cross-sectional view of the pet carrier 2700 according to the seventh embodiment of the second aspect of this disclosure. Figures 18C and 18D are schematic diagrams of the stop member 2728 according to the seventh embodiment of the second aspect of this disclosure from different perspectives. Figure 19A is a schematic diagram of the appearance of the pet carrier 2800 according to the eighth embodiment of the second aspect of this disclosure. Figure 19B is a schematic cross-sectional view of the pet carrier 2800 according to the eighth embodiment of the second aspect of this disclosure. Figure 19C is a schematic diagram of the stop member 2828 according to the eighth embodiment of the second aspect of this disclosure. Figure 19D is a schematic cross-sectional view of the stop member 2828 according to the eighth embodiment of the second aspect of this disclosure. As shown in Figures 18A to 18D, unlike the stop 2628 of the sixth embodiment, the stop 2728 of this embodiment can be a webbing loop, and the webbing loop has multiple protrusions 27281 formed thereon, which can contact the binding webbing 2721 to increase the frictional force of the webbing loop acting on the binding webbing 2721. As shown in Figures 19A to 19D, unlike the stop 2628 of the sixth embodiment, the stop 2828 of this embodiment can be a webbing clip, and the webbing clip has at least one protrusion 28281 formed thereon, which can contact the binding webbing 2821 to increase the frictional force of the webbing clip acting on the binding webbing 2821. Other structures of this embodiment are similar to those of the fourth embodiment and also have similar variations, which will not be described in detail here for the sake of simplicity. In addition, it is understood that in another embodiment, the elongation of the binding webbing can also be limited by a stopping mechanism similar to that of the stop or other mechanisms. Compared to existing technologies, the pet carrier of the second aspect of this disclosure can confine the pet within the accommodating space by using restraint webbing threaded through the bottom opening to engage with the connector of the pet vest worn by the pet. Therefore, the pet carrier of the second aspect of this disclosure can improve the safety of pets when riding.It should be noted that the pet carrier of the second aspect of this disclosure can also be equipped with an integrated securing device (such as the "integrated securing device" described in the embodiments of the first aspect of this disclosure) to be installed on the vehicle seat. That is, it can be stably fixed to the vehicle seat directly by the integrated securing device without the need for a separate fixing base or a base with supporting feet. In the third aspect of this disclosure, a pet travel system or animal travel system is also provided, particularly a pet travel system or animal travel system for securing a pet or animal in a vehicle. Specifically, the pet travel system includes a pet travel device for securing a pet or animal wearing wearables such as a chest harness or vest, and such wearables for pets. The pet travel system according to this disclosure can provide secure support for pets or animals in a vehicle to prevent the pet from being impacted or injured due to sudden changes in vehicle speed. Referring to Figure 20, the pet transportation device 310 according to this disclosure includes a pet carrier 312 and a base 314, the pet carrier 312 being mounted and secured to the base 314. The base 314 can be mounted in a vehicle (not shown in the figure), and the pet carrier 312 is mechanically mounted to the base 314 via locking mechanisms (not shown in the figure) located respectively on the bottom of the pet carrier 312 and on the base 314. The pet carrier 312 is mainly composed of a seat 3121 and a housing 3122 (also referred to as a "carrying box", similar to the "carrying box" in the first and second aspects of this disclosure) embedded in the seat 3121, and may optionally include a detachable handle 3123 (also referred to as a "carrying handle") connected to opposite sides of the pet carrier 312 via pivots 3123A and 3123B (also referred to as "attachment mechanisms"). Based on practical considerations and expectations, the seat 3121 is made of plastic, wood, metal, or any material with a certain degree of rigidity, and functions to be mounted to the base 314 via a locking bar (not shown) thereon. The crate 3122, which defines the pet-accommodating space S3, can be made of cushioning or foam materials, such as EPP (expanded polypropylene) or EPS (expandable polystyrene), to reduce the impact on the pet contained in the crate 3122 caused by rapid changes in vehicle speed.Optionally, the height of the housing 3122 may cover some or all of the pivots 3123A and 3123B to protect the pet's body or head from direct impact with the handle 3123. According to this disclosure, when wearing wearables such as a chest harness or pet vest, a pet or animal (such as a dog) can be restrained and secured within the housing 3122 of the pet mobility device 310. The pet mobility device 310 and the wearables (which may be further described below) are designed and constructed to provide stable and secure support for the pet by combining the pet mobility device and the wearables. More specifically, the pet mobility system of this disclosure (including the pet mobility device 310 and the wearables for the pet) can apply supportive forces to the pet or animal's body at certain locations (e.g., at least at the shoulder blades, as shown in FIG. 21), thereby achieving safe and stable support for the pet or animal during vehicle movement. Turning to FIGS. 22 through 34, these figures schematically illustrate pet mobility devices, particularly pet vehicles, according to various embodiments of this disclosure. It should be noted that, for clarity, the handle of the pet carrier according to this disclosure has been omitted in these figures. Furthermore, the serial numbers of the embodiments, such as first, second, etc., are used only to distinguish these embodiments and do not indicate any preference for these embodiments. Referring to FIG22, FIG22 schematically shows a top view of a pet carrier 332 of a pet travel device according to a first embodiment of a third aspect of this disclosure. The pet carrier 332 shown includes a box portion 3322 embedded with a seat portion (not shown) and a detachable handle (not shown). The box portion 3322, and therefore the pet carrier 332, is substantially rectangular, and the handle is attached to the opposite long side of the pet carrier 332. In this embodiment, the handle is attached to the pet carrier 332 near the front of the pet carrier 332 (in the direction indicated by arrow F). For example, the handle can be detached from the pet carrier 332 when the pet carrier 332 is mounted on a vehicle base (not shown). In this embodiment, the pet carrier 332 includes two slots 3324A and 3324B (also referred to as "bottom openings") formed on and extending through its bottom. More specifically, slots 3324A and 3324B are formed and opened on the bottom 3322B of the box portion 3322 and extend through the seat portion of the pet carrier 332 to allow corresponding straps (hereinafter referred to as "shoulder straps") 336A and 336B to pass through.The pet carrier 332 also includes a carrying strap 338 extending from a slot 3326, secured to the bottom 3322B of the carrier portion 3322, and located near the rear of the pet carrier 332 (in the direction indicated by arrow R). In this embodiment, two shoulder straps 336A and 336B can be connected to the carrying strap 338 to restrain the pet or animal within the carrier portion 3322. As shown in FIG22, the shoulder straps 336A and 336B include corresponding tongues 3362A and 3362B at their ends, which are connected thereto, while the carrying strap 338 includes a buckle clip 3382 at its ends, allowing the tongues 3362A and 3362B to be inserted into or snapped into the buckle clip 3382 for fastening. Optionally, shoulder straps 336A and 336B can be locked to carrier straps 338 by various fastening devices 3382, including but not limited to clips, cam locks, fasteners, lock catches, hasps, and snap locks. Please refer to Figure 23, which schematically shows a top view of a pet carrier 342 of a pet mobility device according to a second embodiment of the third aspect of this disclosure. As shown, the pet carrier 342 has a structure and construction similar to that of the pet carrier 332, including a carrier portion 3422, grooves 3424A and 3424B formed on the bottom 3422B of the carrier portion 3422 of the pet carrier 3422, shoulder straps 346A and 346B, and fastening devices such as tongues 3462A and 3462B for the corresponding shoulder straps 346A and 346B. The pet carrier 342 differs from the pet carrier 332 in FIG. 22 in that, in this embodiment, the pet carrier 342 includes two carrying straps 348A and 348B, which are constructed on opposite long sides of the carrier portion 3422 and located at corresponding positions near the rear of the pet carrier 342 (in the direction indicated by arrow R). More specifically, the pet carrier 342 includes pairs of slots 3426A, 3426B (and optionally, pairs of slots 3426C, 3426D), each slot being formed on a corresponding one of the opposite long sides of the carrier portion 3422 near the rear. As shown in FIG. 23, the pairs of slots 3426A, 3426B and the pairs of slots 3426C, 3426D are formed on the corresponding long sides of the carrier portion 3422 and are spaced apart at a defined distance.The paired straps 348A and 348B can be arranged to extend optionally from slots 3426A and 3426B, or from slots 3426C and 3426D, depending on the size of the pet to be housed in the carrier portion 3422. In this embodiment, the paired slots 3426A and 3426B, as well as the paired slots 3426C and 3426D, are formed to penetrate the bottom 3422B of the carrier portion 3422 and the bottom of the seat portion (not shown), such that the paired straps 348A and 348B can extend from the back of the pet carrier 342 (i.e., from the seat portion) and be exposed in the carrier portion 3422. When the carrying straps 348A and 348B extend adaptively from the paired slots 3426A and 3426B or from the paired slots 3426C and 3426D, they can be held in place by corresponding fastening members (e.g., fastening member 3484A). Similarly, the shoulder straps 346A and 346B can be latched to the corresponding carrying straps 348A and 348B by various fastening devices 3482A and 3482B, including but not limited to clips, cam locks, fasteners, latches, buckles, and spring locks. Please refer to Figure 24, which schematically shows a top view of a pet carrier 352 of a pet travel device according to a third embodiment of the third aspect of this disclosure. The pet carrier 352 shown in the figure has a structure and construction similar to that of the pet carrier 342, including a box portion 3522, grooves 3524A and 3524B formed on the bottom 3522B of the box portion 3522 of the pet carrier 352, shoulder straps 356A and 356B, and fastening devices such as tongues 3562A and 3562B for the corresponding shoulder straps 356A and 356B. The pet carrier 352 differs from the pet carrier 342 of FIG. 23 in that, in this embodiment, the straps 358A and 358B are connected to corresponding adjusting straps 3586A and 3586B, or optionally, to corresponding adjusting straps 3586C and 3586D, thereby securing them to the carrier section 3522. More specifically, the pairs of adjusting straps 3586A and 3586B (and optionally the pairs of adjusting straps 3586C and 3586D) are secured to the bottom 3522B of the carrier section 3522 near the rear of the pet carrier 352 (in the direction indicated by arrow R). As shown in FIG. 24, the pairs of adjusting straps 3586A and 3586B and the pairs of adjusting straps 3586C and 3586D are secured to the respective long sides of the carrier section 3522 and are spaced apart at a defined distance.The free end of each of the adjusting straps 3586A, 3586B, 3586C, and 3586D is connected to ladder locks 3584A, 3584B, 3584C, and 3584D, and to the corresponding carrier straps 358A and 358B, and further to the corresponding shoulder straps 356A and 356B. In other words, shoulder straps 356A and 356B can be latched to carrier straps 358A and 358B, which are optionally connected to adjusting straps 3586A and 3586B, or to adjusting straps 3586C and 3586D, depending on the size of the pet to be housed in the carrier section 3522. Similarly, shoulder straps 356A and 356B can be latched to corresponding carrier straps 358A and 358B by various fastening devices 3582A and 3582B, including but not limited to clips, cam locks, fasteners, latches, buckles, and spring locks. Referring to Figure 25, Figure 25 schematically shows a top view of a pet carrier 362 of a pet travel device according to a fourth embodiment of the third aspect of this disclosure. As shown, the pet carrier 362 has a structure and construction similar to the pet carrier 352, including a carrier portion 3622, grooves 3624A and 3624B formed on the bottom 3622B of the carrier portion 3622B of the pet carrier 362, and fastening devices such as tongues 3662A and 3662B for the corresponding shoulder straps 366A and 366B. Furthermore, the design and construction of the carrier straps shown in Figure 23 or Figure 24 (e.g., slots, adjustment buckles, and adjustment straps with ladder locks) are suitable for carrier straps 368A and 368B in this embodiment. The pet carrier 362 differs from the pet carrier 352 of Figure 24 in that, in this embodiment, shoulder straps 366A and 366B are combined with a pet harness 365 (or vest) for wearing on a pet or animal. More specifically, the pet harness 365 includes, for example, four straps 3651 to 3654 extending from its center. As shown in Figure 25, in this embodiment, the free ends of the paired shoulder straps 3651 and 3652 are connected to a male buckle 3651A and a female buckle 3652A, respectively, so that the paired shoulder straps 3651 and 3652 can be fastened to surround the body of the pet or animal. Similarly, the free ends of the pair of carrying straps 3653 and 3654 are connected to the corresponding male buckle 3653A and female buckle 3654A, so that the pair of carrying straps 3653 and 3654 can be fastened to surround the body of the pet or animal around the chest or abdomen.Straps 3651 and 3653 are anchored to shoulder strap 366A at defined locations (e.g., the centers of straps 3651 and 3653). Similarly, straps 3652 and 3654 are anchored to shoulder strap 366B at defined locations (e.g., the centers of straps 3652 and 3654). In this way, when tongues 3662A and 3662B are inserted into or snapped into corresponding clips 3682A and 3682B for fastening, the pet carrier 362 allows for relatively more stable and secure support for the pet. It is worth noting that when a pet restrained in the pet carrier is unwilling or resists wearing wearables, or when the pet owner is unwilling to allow their pet to wear wearables, the pet carrier 362, which integrates wearables with straps 366A and 366B, can be used to carry the pet. By integrating wearable devices such as vests or harnesses with the straps of the pet carrier, discomfort and stress in pets can be reduced. Similarly, shoulder straps 366A and 366B can be latched to corresponding carrier straps 368A and 368B via various fastening devices, including but not limited to clips, cam locks, fasteners, buckles, latches, and spring locks. Figures 26A and 26B schematically show bottom views of pet carriers according to the first, second, third, and fourth embodiments of the third aspect of this disclosure, particularly the seat of the pet carriers (e.g., pet carriers 332, 342, 352, and 362). More specifically, as shown in Figures 26A and 26B, the seat portion 3721 is adapted to housing portions 3322, 3422, 3522, or 3622. This means that housing portions 3322, 3422, 3522, and 3622 can be fitted into the seat portion 3721 of Figures 26A and 26B. The seat portion 3721 can be engaged with the seat mounting portion of the base (e.g., seat mounting portion 3154 as shown in Figure 34) via two locking levers 378A and 378B provided on the bottom 3721B, thus connecting it to the base to be installed in a vehicle (not shown in the figures). In this embodiment, the two locking levers 378A and 378B are arranged parallel to the long side of the seat portion 3721, and through the two locking levers 378A and 378B, the pet carrier can be engaged with the base in the lateral direction of the base (i.e., the direction indicated by arrow R), parallel to the rear seat of the vehicle. As shown in Figure 26A, the seat 3721 includes two slots 3724A and 3724B, which pass through the bottom 3721B of the seat 3721 and the bottom of the box (not shown in the figure).Two straps 376A and 376B (hereinafter referred to as "shoulder straps") can pass through corresponding slots 3724A and 3724B to extend from and be exposed here from slots (e.g., slots 3324A, 3324B, 3424A, 3424B, 3524A, 3524B and 3624A, 3624B) formed in the bottom of the case, as shoulder straps as previously described (e.g., shoulder straps 336A, 336B, 346A, 346B, 356A, 356B and 366A, 366B). The two shoulder straps 376A and 376B are anchored to a connecting portion 3762, to which a fixing strip 3764 is connected. The connecting part 3762 can be a separate connector, such as a T-shaped connector or a clamp, or it can be formed by sewing together two shoulder straps 376A and 376B. The seat 3721, located near the rear of the pet carrier (in the direction of arrow R), has a positioning buckle 3726 (also referred to as a "fixing mechanism") at the center of its short side. The fixing strap 3764, passing through the positioning buckle 3726, can be fixed in a specific position, such that the length of the fixing strap 3764 is fixed after adjustment. In other words, the positioning buckle 3726 allows adjustment of the tightness of the fixing strap 3764 and the shoulder straps 376A and 376B to accommodate a pet or animal secured in the carrier by shoulder straps as described above. In this embodiment, the bottom 3721B of the seat portion 3721 is provided with fixing blocks 3781A, 3782A, 3781B, and 3782B at both ends of each locking lever 378A and 378B. More specifically, fixing blocks 3781A and 3782A are located at both ends of the locking lever 378A, while fixing blocks 3781B and 3782B are located at both ends of the locking lever 378B. When the locking levers 378A and 378B are attached to the corresponding restraints of the seat mounting portion (e.g., the corresponding restraints 3154A and 3154B of the seat mounting portion 3154 as shown in FIG. 34), the locking levers 378A and 378B may be restricted from movement due to being blocked by the fixing blocks 3781A, 3782A, 3781B, and 3782B arranged at both ends. Furthermore, by providing fixing blocks 3781A and 3782A, 3781B and 3782B at both ends, the fixing strength and stability of the locking rods 378A and 378B attached to the seat 3721 can be enhanced. In this embodiment, the fixing blocks 3781A, 3782A, 3781B and 3782B can be integrally formed with the seat 3721 of the pet carrier.Optionally, the securing block can be a separate structure that is suitably attached to the seat of the pet carrier. According to this disclosure, the positioning buckle 3726 allows the user (pet owner) to adjust the tightness of the harness, thereby adjusting the shoulder strap tightness, and to secure the length of the securing strip in a simple manner. For this purpose, the positioning buckle 3726 can include, but is not limited to, so-called "A-locks," buckles or clips, pulley locks, etc. In this embodiment, the positioning buckle 3726 can be an "A-lock," which is known to those skilled in the art and is commonly used in existing car seats. Optionally, the pet carrier (e.g., pet carriers 332, 342, 352, and 362) can be engaged with a base (not shown) mounted in the vehicle via locking bars 378A and 378B arranged along the long side transverse to the seat 3721, as shown in FIG26B. In other words, the pet carrier can be engaged with the base in a direction parallel to the base (i.e., in the direction transverse to the rear seat of the vehicle, as indicated by arrow R) via two locking levers 378A and 378BS. In this embodiment, the fixing strap 3764 can be stored in the space between the bottom 3721B of the seat portion 3721 and the pair of locking levers 378A and 378B to prevent swaying. It should be noted that for pet carriers having at least one pair of slots for the carrying straps (e.g., pet carrier 342 shown in FIG. 23), the pair of slots can be formed respectively through the bottom of the box portion (not shown) and the bottom 3721B of the seat portion 3721, such that the pair of carrying straps (e.g., carrying straps 348A and 348B) can extend from them to be exposed in the box portion. Please refer to FIG. 27, which schematically shows a top view of a pet carrier 382 of a pet travel device according to a fifth embodiment of the third aspect of this disclosure. The pet carrier 382 shown in the figure has a similar structure and construction to the pet carrier 352, including a carrier portion 3822, shoulder straps 386A and 386B, carrier straps 388A and 388B, adjusting straps 3886A to 3886D with corresponding ladder locks 3884A to 3884D connected to their free ends, and fastening devices such as tongue-shaped pieces 3862A and 3862B and buckle clips 3882A and 3882B for the corresponding shoulder straps 386A and 386B. The difference between the pet carrier 382 and the pet carrier 352 of Figure 24 is that, in this embodiment, four slots 3824A to 3824D are formed on the bottom 3822B of the carrier portion 3822.Pairs of slots 3824C and 3824D are formed closer to the front of the pet carrier 382 (in the direction of arrow F) than pairs of slots 3824A and 3824B. The two pairs of slots 3824A and 3824B, 3824C and 3824D provide the ability to adjust shoulder straps 386A and 386B to accommodate pets of different sizes. More specifically, when the pet's size is relatively small, shoulder straps 386A and 386B can selectively extend from slots 3824A and 3824B to latch onto carrier straps 388A and 388B connected to adjusting straps 3886C and 3886D. When the pet is relatively large, shoulder straps 386A and 386B can extend from slots 3824C and 3824D to latch onto carrier straps 388A and 388B connected to adjusting straps 3886A and 3886B. Similarly, shoulder straps 386A and 386B can be latched onto corresponding carrier straps 388A and 388B via various fastening devices, including but not limited to clips 3882A and 3882B, cam locks, fasteners, latches, buckles, and spring locks. Please refer to Figure 28, which schematically shows a top view of a pet carrier 392 of a pet travel device according to a sixth embodiment of the third aspect of this disclosure. The pet carrier 392 shown in the figure has a similar structure and construction to the pet carrier 382, ​​including a housing portion 3922, shoulder straps 396A and 396B, grooves 3924A to 3924D formed on the bottom 3922B of the housing portion 3922B, fastening devices such as tongues 3962A and 3962B for the corresponding shoulder straps 396A and 396B, carrier straps 98A and 98B, and fastening devices such as clips 3982A and 3982B. The difference between the pet carrier 392 and the pet carrier 382 of Figure 27 is that, in this embodiment, the adjustment straps 3986A to 3986D are arranged on the bottom 3922B ± of the housing portion 3922, rather than on its opposite long side. As shown in Figure 28, paired adjustment straps 3986A and 3986B are formed on the bottom 3922B of the housing 3922, located closer to the rear of the pet carrier 392 (in the direction of arrow R) than paired adjustment straps 3986C and 3986D. In this embodiment, the spacing between the paired adjustment straps 3986A and 3986B (or 3986C and 3986D) is reduced. Compared to the pet carrier 382 described above, the pet carrier 392 is more suitable for securing relatively slender pets.Similarly, shoulder straps 396A and 396B can be latched to corresponding carrying straps 98A and 98B by various fastening devices, including but not limited to clips 3982A and 3982B, cam locks, fasteners, latches, buckles, and spring locks. Figure 29 schematically shows a bottom view of a pet carrier (e.g., pet carrier 382 or 392) according to the fifth and sixth embodiments of the third aspect of this disclosure. More specifically, the seat portion 31021 shown in Figure 29 is adapted to the carrying box portion 3822 or 3922, meaning that the carrying box portion 3822 or 3922 can be fitted into the seat portion 31021 of Figure 29. The seat portion 31021 can be engaged with a seat mounting portion of the base (not shown in the figure) mounted in a vehicle by two locking bars 31O8A and 31O8B arranged on the bottom 31021B. As shown in Figure 29, the seat portion 31021 has a similar structure and construction to the seat portion 3721 of Figures 26A and 26B, including shoulder straps 3106A and 3106B, a fixing strap 31064, and a positioning buckle 31026. The seat portion 31021 shown differs from the seat portion 3721 of Figures 26A and 26B in that, in this embodiment, it has four slots 31024A to 31024D formed at the bottom 31021B± of the seat portion 31021 and extending through the bottom 31021B. Pairs of slots 31024C and 31024D are formed closer to the front of the seat portion 31021 (in the direction indicated by arrow F) than the pairs of slots 31024A and 31024B. Two pairs of slots 31024A and 31024B, 31024C and 31024D provide the ability to adjust the shoulder straps (not shown) to accommodate pets of different sizes. More specifically, when the pet is relatively small, the harnesses 3106A and 3106B can selectively extend from slots 31024A and 31024B to extend from and be exposed in slots formed at the bottom of the carrier (slots 3824A and 3824B as shown in Figure 27 and slots 3924A and 3924B as shown in Figure 28), serving as the aforementioned shoulder straps. Alternatively, when the pet is relatively large, the harnesses 3106A and 3106B may optionally extend from the slots 31024C and 31024D to extend from and be exposed as shoulder straps in the slots formed at the bottom of the carrier (slots 3824C and 3824D as shown in Figure 27 and slots 3924C and 3924D as shown in Figure 28).Furthermore, in this embodiment, the connecting portion 31062 is a T-shaped connector that connects the two shoulder straps 3106A and 3106B and the fixing strip 31064. More specifically, the two shoulder straps 3106A and 3106B are connected to the connecting portion 31062 by passing the two arms of the T-shaped connector through corresponding loops formed at the free ends of each shoulder strap 3106A and 3106B. The fixing strip 31064 is connected to the connecting portion 31062, particularly to the pillar of the T-shaped connector, for quickly and easily changing the extension of the shoulder straps 3106A and 3106B between different pairs of slots, for example, for extending the shoulder straps 3106A and 3106B from paired slots 31024A and 31024B, or for extending the shoulder straps 3106A and 3106B from paired slots 31024C and 31024D. As shown in Figure 29, an adjustable fixing strap 31064, with one end connected to the connecting part 31062, passes through the positioning buckle 31026 and can be fixed in a certain position to fix the length of the adjusted fixing strap 31064. In other words, the tightness of the fixing strap 31064 and the carrying straps 3106A and 3106B can be adjusted by the positioning buckle 31026 to accommodate the pet or animal being secured in the carrier by the shoulder straps as described above. Similarly, in this embodiment, the positioning buckle 31026 is an "A-lock". However, this disclosure is not limited thereto. Please refer to Figure 30, which schematically shows a top view of a pet carrier of a pet travel device according to a seventh embodiment of the third aspect of this disclosure. The pet carrier 3112 shown in the figure has a similar structure and construction to the pet carrier 352, including a box portion 31122 and fastening devices such as tongue-shaped members 31166A and 31166B for the corresponding shoulder sections 31164A and 31164B. Furthermore, the main design and construction of the carrier straps shown in Figure 24 (e.g., adjusting buckles, adjusting straps with ladder locks) are applicable to the carrier straps 3118A and 3118B of this embodiment. The difference between the pet carrier 3112 shown in the figure and the pet carrier 352 of Figure 24 is that, in this embodiment, only one groove 31124 is formed at the bottom 31122B ± of the box portion 31122, and the shoulder straps have a Y-shaped construction. More specifically, the Y-shaped belt includes an extension segment 3116 and two separate shoulder segments 31164A and 31164B, which are connected to the extension segment 3116 via a connecting portion 31162.The groove 31124 is formed through the bottom 31122B and the seat (not shown) of the box portion 31122, so that the extension segment 3116 of the Y-shaped strap can extend from the bottom of the seat and be connected to the shoulder segments 31164A and 31164B via the connecting portion 31162. The shoulder segments 31164A and 31164B include corresponding fastening devices, such as tongues 31166A and 31166B connected to their respective ends, for fixing to fastening devices, such as the clips 31182A and 31182B of the corresponding box straps 3118A and 3118B. Similarly, shoulder sections 31164A and 31164B can be latched to a pair of carrying straps 3118A and 3118B, which are optionally connected to adjusting straps 31186A and 31186B, or to adjusting straps 31186C and 31186D, depending on the size of the pet to be housed in the carrying case 31122. Similarly, shoulder sections 31164A and 31164B can be latched to the corresponding carrying straps 3118A and 3118B by various fastening devices, including but not limited to clips, cam locks, fasteners, latches, buckles, and spring locks. Figure 31 schematically shows a bottom view of a pet carrier (e.g., pet carrier 3112) according to a seventh embodiment of the third aspect of this disclosure. More specifically, as shown in Figure 31, the seat portion 31221 is adapted to the housing portion 31122, meaning that the housing portion 31122 can be fitted into the seat portion 31221 of Figure 31. The seat portion 31221 can be engaged with the seat mounting portion of the base (not shown in the figure) installed in the vehicle by two locking rods 3128A and 3128B arranged on the bottom 31221B. As shown in Figure 31, the seat portion 31221 includes a groove 31224 that extends through its bottom 31221B and the bottom of the housing portion (not shown in the figure). The groove 31224 corresponds to the groove 31124 shown in Figure 30. The strap (hereinafter referred to as the "strap") 3126 can pass through the groove 31224, extend from the groove 31122B ± formed in the bottom of the box portion 31122 (as shown in FIG30) and remain there as an extension segment 3116 of the Y-shaped strap as described above (as shown in FIG30).Similarly, at the center of the short side of the seat 31221, near the rear of the pet carrier (in the direction indicated by arrow R), the seat 31221 is provided with a positioning buckle 31226. A fixing strap 31264 passing through the positioning buckle 31226 can be fixed in a specific position, thus fixing the length of the fixing strap 31264 after adjustment. In other words, the positioning buckle 31226 allows adjustment of the tension of the fixing strap 31264 and the Y-shaped strap to accommodate a pet or animal secured in the carrier by the shoulder of the Y-shaped strap, as described above. Similarly, in this embodiment, the positioning buckle 31226 is an "A-lock" for the user (pet owner) to adjust the tension of the Y-shaped strap and easily fix the length of the fixing strap. However, this disclosure is not limited to this. Please refer to Figures 32 and 33, which illustrate a pet carrier of a pet transportation device according to an eighth embodiment of the third aspect of this disclosure. Figure 32 schematically shows a top view of the housing 31322 of the pet carrier 3132 of this embodiment, and Figure 33 schematically shows a bottom view of the seat 31421 of the pet carrier 3132 of this embodiment. Furthermore, Figures 32A, 32B, 33A, and 33B schematically show enlarged views of various positioning fasteners of the pet carrier. The seat 31421 can be engaged with a mounting mechanism of the base via two locking rods 3148A and 3148B arranged on the bottom 31421B, and is mounted on a base (not shown in the figures). The pet carrier 3132, including the housing 31322 and seat 31421 as shown, differs from the pet carrier of the previous embodiment. As shown in Figure 32, fastening belts 3136A and 3136B, spaced apart by a predetermined interval, extend from the base 31421 through the interface between the bottom 31322B and one long side L1 of the housing 31322. Fixing belts 3138A and 3138B are fixed to another long side L2 (opposite to side L1), with a predetermined interval between them. Fastening belts 3136A and 3136B are secured to fixing belts 3138A and 3138B by appropriate fastening devices. Optionally, the fixing straps 3138A and 3138B can adopt a structure and arrangement similar to the straps in the foregoing embodiments (e.g., strap 348B in FIG. 23). That is, the fixing straps 3138A and 3138B can extend from the slot or bottom opening provided in the bottom 31322B and be fixed to the bottom 31322B. Specifically, for example, they can be fixed at the interface between the bottom 31322B and the other long side L2.As shown in Figure 33, the two fixing strips 31364A and 31364B can pass through corresponding grooves formed at the interface between the bottom 31421B and the seat 31421 (or the box 31322) on one long side L1, and can extend from there to expose the bottom 31322B±, serving as the fastening strips 3136A and 3136B as described above. The fixing strips 31364A and 31364B (one end of each fixing strip passes through the corresponding positioning buckle 31326A or 31326B) can be fixed in a defined position to fix the length of the fixing strips 31364A and 31364B after adjustment. In other words, the tightness of the securing straps 31364A and 31364B, as well as the fastening straps 3136A and 3136B, can be adjusted using the positioning buckles 31326A and 31326B to accommodate pets or animals secured in the carrier by shoulder straps as described above. In this embodiment, the positioning buckles 31326A and 31326B allow the user (the pet owner) to easily adjust the tightness of the fastening straps and secure the length of the securing straps. For this purpose, the positioning buckles may include, but are not limited to, so-called "A-locks," clips or locking clips, pulley locks, cam buckles, tri-glide buckles, etc. In this embodiment, the positioning fasteners 31326A and 31326B can be cam buckles (positioning fastener 31326A as shown in Figures 32A and 33A) or D-ring buckles (positioning fastener 31326A as shown in Figures 32B and 33B). It is noteworthy that the webbing, straps, and strips of the pet carrier according to this disclosure can be made of the same material as the vehicle's seat belts, thus exhibiting increased safety strength. Referring to Figure 34, a perspective view of the base of a pet travel device according to an embodiment of this disclosure is schematically shown. The base 315, as shown, can be installed in a vehicle (not shown), with its load leg 3152 contacting the vehicle floor, and the pet carrier according to this disclosure can be mechanically mounted to it via a locking mechanism (e.g., two locking levers) on the bottom of the pet carrier (not shown). More specifically, the base 315 will be placed on a vehicle seat (not shown), securely attached to an anchor point, such as its ISOFIX connector 3156. The load-bearing legs 3152 of the base 315 can extend to the vehicle floor. With the load-bearing legs 3152 in full contact with the vehicle floor panel, the base 315 can be securely supported.The base 315 includes a seat mounting portion 3154 for receiving and securing the seat of a pet carrier, such that the pet carrier can be securely attached to the base 315. More specifically, the pet carrier according to this disclosure can be securely latched to the base by latching locking levers (e.g., locking levers 378A and 378B, 378A and 378B as described above, 3108A and 3108B, 3128A and 3128B, 3148A and 3148B) provided on the bottom of its seat to corresponding restraint portions 3154A and 3154B of the seat mounting portion 3154. In one embodiment of this disclosure, the seat mounting portion 3154 of the base 315 is rotatable, thereby allowing the orientation of the pet carrier to change with the rotation of the seat mounting portion 3154, for example, from a direction transverse to the vehicle seat to a direction parallel to the vehicle seat. In order to carry a pet using the pet mobility device (including a pet carrier and a base) of this disclosure and to secure the pet in a vehicle using the pet mobility device, the pet owner will have their pet wear a wearable, such as a pet vest 316 (also referred to as a "pet harness"), including a chest pad 3162 and webbing loops 3164A and 3164B thereon, as shown in FIG35. Preferably, the wearable is designed to fit the pet carrier according to this disclosure. Wearables for pets according to this disclosure, such as pet vests or harnesses, can preferably be designed to fit the pet carrier of the previous embodiments. FIGS. 36A to 36F schematically show perspective views of corresponding wearables according to various embodiments of this disclosure. It should be noted that the main structure of the wearable is similar to commercially available wearables known to those skilled in the art, and therefore will not be repeated here to avoid obscuring the features of this disclosure. The vest shown in Figure 36A is likely similar to existing vests, meaning that currently commercially available vests can also be used in the pet mobility system disclosed herein, thereby providing a strong and stable support for pets in moving vehicles. The vest 317A, as shown, includes a chest pad 3171, shoulder straps 31710A and 31710B extending from the upper part of the chest pad 3171, and a central strap 31715o connecting the shoulder straps 31710A and 31710B to back straps 31714A and 31714B extending from the lower part of the chest pad 3171. Back straps 31714A and 31714B, having corresponding buckles 31713A and 31713B, can form a closed structure with the chest pad 3171 used to surround the pet's upper chest, and the back straps can form a closed structure with the chest pad 3171 used to surround the pet's abdomen.In the central stripe 31715 ±, webbing 31717 is sewn together to form a loop with the central stripe 31715. Webbing 31717 passes through the loop member 31716, allowing the loop member 31716 to move along the webbing 31717 within the loop formed by the webbing 31717 and the central stripe 31715. When the vest 317A is worn, the pet's head will face the direction indicated by arrow H. Please refer to Figure 36B. The structure and construction of the vest 317B shown in Figure 36B are similar to those of the vest 317A in Figure 36A, including a chest pad 3172, chest strips 31720A and 31720B, back strips 31724A and 31724B, and a central stripe 31725 connecting the chest strips 31720A and 31720B with the back strips 31724A and 31724B. The vest 317B shown in the figure differs from the vest 317A in Figure 36A in that, in this embodiment, the annular member 31726 is passed through the central strip 31725 itself. Furthermore, it has webbing 31721A and 31721B that are attached, for example, by sewing to the corresponding chest strips 31720A and 31720B to form corresponding loops, and webbing loops 31722A and 31722B that are attached to the corresponding back strips 31724A and 31724B to form corresponding loops. When wearing vest 317B, the pet's head will face the direction indicated by arrow H. Please refer to Figure 36C. Vest 317C, as shown in the figure, has a similar structure and construction to vest 317B of Figure 36B, including a chest pad 3173, chest straps 31730A and 31730B, webbing 31731A and 31731B attached to the chest straps 31730A and 31730B, and back straps 31734A and 31734B. The difference between the two vests 317C and 317B is that, in this embodiment, the back straps 31734A and 31734B are respectively provided with corresponding quick-release buckles 31733A and 31733B, and the webbing 31737 is attached to the central strap 31735, for example by sewing, and is passed through by an annular member 31736, such that the annular member can be movable when a loop is formed by the webbing 31737 and the central strap 31735. Similarly, when wearing vest 317C, the pet's head will face the direction indicated by arrow H.Referring to Figure 36D, the vest 317D shown has a similar structure and construction to the vest 317B of Figure 36B, including a chest pad 3174, chest straps 31740A and 31740B, back straps 31744A and 31744B, a central strap 31745, and an annular member 31746 through which the central strap 31745 passes. The difference between the two vests 317D and 317B is that, in this embodiment, the webbing attached to the respective straps of vest 317D is not exposed. More specifically, webbing 31741A and 31741B are attached to the respective chest straps, for example by sewing, at a position on the inner surface of the straps. Webbing 31742A and 31742B are attached to the respective back straps, for example by sewing, at a position on the inner surface of the straps. In this way, the corresponding loops formed by the webbing and chest or back straps are located inside the strap body to reduce the possibility of damage or breakage. Furthermore, when wearing vest 317D, the pet's head will face the direction indicated by arrow H. It should be noted that in the embodiments of Figures 36A to 36D above, the "shoulder straps" and "chest straps" may be referred to as the first straps, and the "back straps" may be referred to as the second straps, wherein the first and second straps are spaced apart. Please refer to Figure 36E, which schematically illustrates another type of vest according to an embodiment of this disclosure. As shown, vest 317E includes a chest pad 3175 and a back pad 3175, both adjustablely connected to each other by corresponding straps, as is known to those skilled in the art in conventional vests. In this embodiment, at positions corresponding to the respective strips connecting the chest pad 3175 and the back pad 3175, webbing 31751A, 31751B, 31752A, and 31752B are provided, for example, by sewing them to the chest pad 3175 and the back pad 3175, thereby forming corresponding loops through the strips and the pad body. In this embodiment, the loops formed by the corresponding webbing and the pad bodies (of the chest pad 3175 and the back pad 3175) are passed through by the corresponding strips. Furthermore, webbing 31755o, which is attached to the back pad 3175 (particularly the center of the back pad 3175) by sewing and forms a central loop with the back pad 3175, ensures that the pet's head will face the direction indicated by arrow H when the vest 317E is worn. Please refer to Figure 36F. As shown in the figure, vest 317F has a similar structure and construction to vest 317E, including a chest pad 3176, a back pad 3176', and webbing 31761A, 31761B, 31762A, and 31762B, which are attached to the chest pad 3176 and the back pad 3176 and form corresponding loops therewith.In this embodiment, the vest 317F differs in that the webbing 31765 is attached to the chest pad 3176 (particularly the center of the chest pad 3176) by stitching, thereby forming a central loop with the chest pad 3176. Furthermore, when wearing the vest 317F, the pet's head will face the direction indicated by arrow H. According to this disclosure, the webbing, straps, and strips of the wearable can be made of the same material as a vehicle's seatbelt, thus exhibiting increased safety strength. It should be understood that the connection between the strips, or the connection between the strip and the pad, can be achieved by any mechanism known to those skilled in the art, including but not limited to clips, D-rings, etc. Combination of Wearable and Pet Mobility Device The pet mobility system according to this disclosure includes the pet mobility device and wearable as described above. By combining various straps of the pet carrier and various strips of the wearable, the pet mobility device according to this disclosure can provide stable and secure support for the pet, especially when the pet is wearing a wearable such as a vest of this disclosure, and the wearable is appropriately adjusted in terms of tightness to fit the pet's size in a moving vehicle. Although not shown, according to some examples, the pet carrier may be in the form of a cradle or stroller, having a structure and construction corresponding to the structure and construction shown and illustrated above for the pet carrier of the pet mobility device of this disclosure. Please refer to Figures 37 and 38, which schematically illustrate a pet mobility system in use according to an embodiment of this disclosure. In this embodiment, taking the pet carrier 332 shown in Figure 22 and the vest (vest 317A shown in Figure 36A) as an example, we illustrate how the combination of the straps of the pet carrier 332 and the strips or strips of the vest provides support for the pet restrained in the box of the pet carrier 332. To avoid obscuring this disclosure, structures or components of the pet carrier 332 or vest that are not essential to the combination of straps / stripes of this disclosure may not be shown in the figures and are not described redundantly. As shown, Figure 37 schematically shows a top view of a pet (such as a dog 31800) wearing the vest of Figure 36A and restrained in the box of the pet carrier 332 of Figure 22, while Figure 38 is a schematic side view of Figure 37.In this embodiment, shoulder straps 336A and 336B extend from slots 3324A and 3324B, are pulled upward to extend along the corresponding two front legs of the dog 31800, pass through the gap between the corresponding two shoulders of the dog 31800 and the corresponding two shoulder straps 31710A and 31710B of the vest worn on the dog 31800, pass through the gap between the back of the dog 31800 and the two carrying straps 31714A and 31714B, and are latched to the buckle 3382 by a tongue (not shown), thereby connecting to the carrier strap 338 of the pet carrier 332. The user (or pet owner) can pull the adjustment strap 3764 to adjust its tightness, and after adjustment, the adjustment strap 3764 is secured with the positioning buckle 3726. Since the adjustment strap 3764 is connected to the two carrying straps (i.e., carrying straps 376A and 376B as shown in Figures 26A and 26B), These two harnesses are the same as the corresponding shoulder straps 336A and 336B of the pet carrier 332, so the tightness of the shoulder straps 336A and 336B can be adjusted by pulling the adjusting strap 3764 to fit the body shape of the dog 31800. Optionally, taking the pet carrier 332 and vest (vest 317D as shown in Figure 36D) as an example, shoulder strap 336A can pass through the corresponding loops formed by webbing 31742A and webbing 31741A, while shoulder strap 336B can pass through the corresponding loops formed by webbing 31742B and webbing 31741B. In this embodiment, the two shoulder straps 336A and 336B extend parallel to each other along both sides of the spine (vertebrae) and form four contact points with the pet vest worn on the dog 31800. Two are shoulder points located at the shoulders (corresponding to the location of the dog's scapula, as shown in Figure 21), for example, the shoulder straps forming a first contact point with the first strap of the pet vest (e.g., its shoulder straps, or in other embodiments, its chest straps); the other two are back points in the mid-back of the dog 31800 (corresponding to the sides of the thoracic vertebrae, as shown in Figure 21), for example, the shoulder straps forming a second contact point with the second strap of the pet vest (e.g., its back straps). Compared to existing transport cages or vests, the four contact points (particularly the two shoulder points, i.e., the first contact points) allow for relatively robust, stable, and secure support for the dog 31800. Please refer to Figures 39 and 40, which schematically illustrate a pet transportation system in use according to an embodiment of this disclosure.In this embodiment, taking the pet carrier 332 shown in FIG. 22 and the vest shown in FIG. 36B as examples, it is illustrated how the combination of the straps of the pet carrier 332 and the strips or bars of the vest provides support for a pet restrained in the box of the pet carrier 332. To avoid obscuring this disclosure, structures or components of the pet carrier 332 or vest that are not essential to the strap / strip combination of this disclosure may not be shown in the figures and are not redundantly described. As shown, FIG. 39 schematically shows a top view of a pet (such as a dog 32000) wearing the vest of FIG. 36B restrained in the box of the pet carrier 332 of FIG. 22, while FIG. 40 is a schematic side view of FIG. 39. In this embodiment, shoulder straps 336A and 336B extend from slots 3324A and 3324B, are pulled upward to extend along the corresponding two front legs of the dog 32000, pass through corresponding loops formed by the shoulder straps and webbing 31721A and 31721B of the vest, pass through corresponding loops formed by the back straps and webbing 31722A and 31722B of the vest, and are latched to clips 3382 via tongues (not shown), thereby connecting to the carrier straps 338 of the pet carrier 332. The user (or pet owner) can pull the adjustment strap 3764 to adjust its tightness, and after adjustment, the adjustment strap 3764 is secured with positioning buckles 3726. Since the adjustment strap 3764 is connected to two harnesses (i.e., harnesses 376A and 376B as shown in Figures 26A and 26B), which are the same straps as the corresponding shoulder straps 336A and 336B of the pet carrier 332, the tightness of the shoulder straps 336A and 336B can be adjusted by pulling the adjustment strap 3764 to fit the body shape of the dog 32000. Similar to the embodiments shown in Figures 37 and 38, in this embodiment, the two shoulder straps 336A and 336B extend parallel to each other along both sides of the spine and form four contact points with the pet vest worn on the dog 32000. Two are shoulder points located on the shoulders (corresponding to the location of the dog's scapula, as shown in Figure 21), for example, the shoulder straps forming a first contact point with the first strap of the pet vest (e.g., its shoulder straps, or in other embodiments, its chest straps); the other two are back points located in the mid-back of the dog 32000 (corresponding to the sides of the thoracic vertebrae, as shown in Figure 21), for example, the shoulder straps forming a second contact point with the second strap of the pet vest (e.g., its back straps). Compared to existing transport cages or vests, four contact points (especially the two shoulder points, i.e., the first contact points) allow for relatively robust, stable, and secure support for the dog 32000.Compared to the embodiments of Figures 37 and 38, shoulder straps 336A and 336B according to this embodiment are further constrained in a loop formed by webbing 31721A, 31721B, 31722A, 31722B and corresponding shoulder straps (or chest straps) or back straps, so that shoulder straps 336A and 336B can always be kept in the proper position during vehicle movement. Please refer to Figures 41 and 42, which schematically illustrate a pet transportation system in use according to an embodiment of this disclosure. In this embodiment, taking the pet carrier 352 shown in Figure 24 and the vest shown in Figure 36B as examples, it is illustrated how the combination of straps of the pet carrier 352 and the straps or strips of the vest provides support for a pet restrained in the box of the pet carrier 352. To avoid obscuring the content of this disclosure, structures or components of the pet carrier 352 or vest that are not essential to the combination of straps / strips of the present disclosure may not be shown in the figures or described redundantly. As shown in the figures, Figure 41 schematically illustrates a top view of a pet (such as a dog 32200) wearing a vest of Figure 36B, restrained within the crate of the pet carrier 352 of Figure 24, while Figure 42 is a schematic side view of Figure 41. In this embodiment, shoulder straps 356A and 356B extend from slots 3524A and 3524B, are pulled upward to extend along the respective two front legs of the dog 32200, pass through corresponding loops formed by webbing 31721A and 31721B and the shoulder straps of the vest, pass through corresponding loops formed by webbing 31722A and 31722B and the back straps of the vest, cross each other and pass through annular member 31726, and are latched to clips 3582B and 3582A by corresponding tongues 3562A and 3562B, thereby connecting to the corresponding crate straps 358B and 358A of the pet carrier 352. More specifically, since shoulder straps 356A and 356B cross at the position of the annular member 31726, shoulder strap 356A can be connected to the carrier strap 358B by engaging the tongue member 3562A in the buckle 3582B, while shoulder strap 356B can be connected to the carrier strap 358A by engaging the tongue member 3562B in the buckle 3582A. Preferably, in this embodiment, for a relatively large dog 32200, carrier straps 358A and 358B are connected to adjusting straps 3586A and 3586B respectively via ladder locks 3584A and 3584B.Similarly, the user (or pet owner) can pull the adjustment strap 3764 to adjust its tightness, and after adjustment, secure the adjustment strap 3764 with the positioning buckle 3726. Since the adjustment strap 3764 is connected to two harnesses (i.e., harnesses 376A and 376B as shown in Figures 26A and 26B), which are the same straps as the corresponding shoulder straps 356A and 356B of the pet carrier 352, the tightness of the shoulder straps 356A and 356B can be adjusted by pulling the adjustment strap 3764 to fit the size of the dog 32200. As shown in Figures 41 and 42, in this embodiment, the two shoulder straps 356A and 356B first extend parallel to each other along both sides of the spine, forming four contact points with the pet vest worn on the dog 32200± (i.e., two shoulder points (i.e., the first contact points) and two back points (i.e., the second contact points), as shown in Figure 38 or Figure 40). They then cross each other to provide another contact point, i.e., the third contact point, at the intersection around the annular member 31726. The two shoulder points are located on the shoulders of the dog 32200 (corresponding to the position of the dog's scapula, as shown in Figure 21), and the two back points are located on the mid-back of the dog 32200 (corresponding to the sides of the thoracic vertebrae, as shown in Figure 21). In this embodiment, the third contact point is located approximately around the back, i.e., near the back straps. Compared to existing transport cages or vests, the four contact points (especially the two shoulder points) allow for relatively robust, stable, and secure support for the dog 32200. Compared to the embodiments of Figures 39 and 40, according to this embodiment, another contact point at the intersection around the annular member 31726 forms a five-point support, thereby allowing for increased support for the dog 32200, which is safer for the dog 32200 in a moving vehicle. Referring to Figures 43 and 44, a pet mobility system in use according to an embodiment of this disclosure is schematically illustrated. In this embodiment, the combination of the straps of the pet carrier 352 shown in Figure 24 and the vest shown in Figure 36C is used as examples to illustrate how the straps of the pet carrier 352 and the strips or bars of the vest provide support for a pet restrained in the cage of the pet carrier 352. To avoid obscuring the content of this disclosure, structures or components of the pet carrier 352 or vest that are not essential to the strap / strip combination of this disclosure may not be shown in the figures or described redundantly. As shown in the figures, Figure 43 is a schematic top view showing a pet (such as a dog 32400) wearing the vest of Figure 36C and restrained in the box of the pet carrier 352 of Figure 24, while Figure 44 is a schematic side view of Figure 43.In this embodiment, shoulder straps 356A and 356B can extend from slots 3524A and 3524B, be pulled upward to extend along the respective two front legs of the dog 32400, pass through the respective loops formed by webbing 31731A and 31731B and the shoulder straps of the vest, cross each other and pass through the ring member 31736, and are latched to clips 3582B and 3582A by corresponding tongues 3562A and 3562B, thereby connecting to the corresponding carrier straps 358B and 358A of the pet carrier 352. More specifically, since shoulder straps 356A and 356B cross at the position of the annular member 31736, shoulder strap 356A can be connected to the carrier strap 358B by engaging the tongue member 3562A in the buckle 3582B, and shoulder strap 356B can be connected to the carrier strap 358A by engaging the tongue member 3562B in the buckle 3582A. In this embodiment, for a relatively large dog 32200, carrier straps 358A and 358B are preferably connected to adjusting straps 3586A and 3586B by ladder locks 3584A and 3584B, respectively. Similarly, the user (or pet owner) can pull the adjustment strap 3764 to adjust its tightness, and after adjustment, secure the adjustment strap 3764 with the positioning buckle 3726. Since the adjustment strap 3764 is connected to two harnesses (i.e., harnesses 376A and 376B shown in Figures 26A and 26B), which are the same straps as the corresponding shoulder straps 356A and 356B of the pet carrier 352, the tightness of the shoulder straps 356A and 356B can be adjusted by pulling the adjustment strap 3764 to fit the body shape of the dog 32400. As shown in Figures 43 and 44, in this embodiment, the two shoulder straps 356A and 356B first extend parallel to each other along both sides of the spine, forming two contact points with the pet vest worn on the dog 32400, i.e., two shoulder points, and then cross each other to provide a third contact point at the intersection around the annular member 31736. The shoulder point is located at the shoulder of the dog 32400 (corresponding to the location of the dog's scapula, as shown in Figure 21), which allows for sturdy, stable, and secure support for the dog 32400 compared to existing transport cages or vests. According to this embodiment, a third contact point at the intersection around the annular member 31736 further allows for increased support for the dog 32400 and is safer for the dog 32400 in a moving vehicle. The shoulder straps of the pet carrier can also be crossed when the pet is wearing an existing vest similar to that shown in Figure 36D to increase support for the pet.Please refer to Figures 45 and 46, which schematically illustrate a pet transportation system in use according to an embodiment of the present disclosure. In this embodiment, taking the pet carrier 352 shown in Figure 24 and the vest shown in Figure 36D as examples, we illustrate how the combination of the straps of the pet carrier 352 and the strips or bars of the vest provides support for a pet restrained in the housing of the pet carrier 352. To avoid obscuring the content of this disclosure, structures or components of the pet carrier 352 or vest that are not essential to the strap / strip combination of the present disclosure may not be shown in the figures or redundantly described. As shown, Figure 45 is a schematic top view showing a pet (such as a dog 32600) wearing the vest of Figure 36D restrained in the housing of the pet carrier 352 of Figure 24, while Figure 46 is a schematic side view of Figure 45. In this embodiment, shoulder straps 356A and 356B extend from slots 3524A and 3524B, are pulled upward to pass through the space between the two front legs of the dog 32600, cross each other at a position around the chest of the dog 32600, extend along the body of the dog 32600 to the back of the dog 32600, cross each other again and extend through the annular member 31746, and are latched to clips 3582A and 3582B by corresponding tongues 3562A and 3562B, thereby connecting to the corresponding carrier straps 358A and 358B of the pet carrier 352. More specifically, since shoulder straps 356A and 356B cross twice at the chest of the dog 32600 and the location of the ring member 31716, shoulder strap 356A can be connected to the carrier strap 358A by engaging the tongue member 3562A in the buckle 3582A, while shoulder strap 356B can be connected to the carrier strap 358B by engaging the tongue member 3562B in the buckle 3582B. In this embodiment, for a relatively large dog 32600, carrier straps 358A and 358B are preferably connected to adjusting straps 3586A and 3586B by ladder locks 3584A and 3584B, respectively. In this embodiment, shoulder straps 356A and 356B are not constrained by any vest straps used to support the dog 32600. Conversely, through the double cross of shoulder straps 356A and 356B, two cross points S31 and S32 are formed relative to dog 32600 on different planes (i.e., one is located around the chest and the other is located around the back).In other words, viewed from the pet's head to its tail, shoulder straps 356A and 356B first cross near the shoulder or chest (such as around the chest), i.e., near the shoulder strap or chest strap (first strap) (crossing point S31), then continue extending and cross again around the back, i.e., near the back strap (second strap) (crossing point S32). Crossing points S31 and S32 form two third contact points between the shoulder straps and the pet's vest, and these two third contact points are generally located at the central strap. More specifically, the two shoulder straps 356A and 356B directly contact the dog's shoulders on the chest side, thus providing basic support to the dog 32600, and the crossing point S31 formed around the dog's chest and the crossing point S32 formed around the dog's back allow for further support from different planes. In this embodiment, the shoulder straps support the dog 32600 in a spirally intertwined manner along the dog 32600, thus allowing for at least two intersections formed by the straps extending along the body of the dog 32600. In this way, compared to existing transport cages or vests, this disclosure allows for relatively robust, stable, and secure support for the dog 32600. Please refer to Figures 47 and 48, which schematically illustrate a pet transportation system in use according to an embodiment of this disclosure. In this embodiment, the combination of the straps of the pet carrier 342 and the strips or bars of the vest (as shown in Figure 36A) shown in Figure 23 is used as an example to illustrate how the combination of the straps of the pet carrier 342 and the strips or bars of the vest provides support for a pet restrained within the cage of the pet carrier 342. To avoid obscuring this disclosure, structures or components of the pet carrier 342 or vest that are not essential to the combination of the straps / strips of this disclosure may not be shown in the figures and are not redundantly described. As shown in the figures, Figure 47 is a schematic top view showing a pet (such as a dog 32800) wearing a vest of Figure 36A and restrained in the box of the pet carrier 342 of Figure 23, while Figure 48 is a schematic side view of Figure 47.In this embodiment, shoulder straps 346A and 346B can extend from slots 3424A and 3424B, be pulled upward to extend along the corresponding two front legs of the dog 32800, pass through the gap between the corresponding two shoulders of the dog 32800 and the corresponding two shoulder straps 31710A and 31710B of the vest worn on the dog 32800, cross each other and extend through the annular member 31716, and then latch to the buckles 3482B and 3482A by the corresponding tongues 3462A and 3462B, thereby connecting to the corresponding carrier straps 348B and 348A of the pet carrier 342. More specifically, since shoulder straps 346A and 346B cross at the location of the annular member 31716, shoulder strap 346A can be connected to carrier strap 348B by the tongue 3462A engaging in the buckle 3482B. The shoulder strap 346B can be connected to the carrier strap 348A by engaging the buckle 3482A with the tongue 3462B. Similarly, the user (or pet owner) can pull the adjustment strap 3764 to adjust its tightness, and after adjustment, secure the adjustment strap 3764 with the positioning buckle 3726. Since the adjustment strap 3764 is connected to two harnesses (i.e., harnesses 376A and 376B shown in Figures 26A and 26B), which are the same straps as the corresponding shoulder straps 346A and 346B of the pet carrier 342, the tightness of the shoulder straps 346A and 346B can be adjusted by pulling the adjustment strap 3764 to fit the size of the dog 32800. As shown in Figures 47 and 48, in this embodiment, the two shoulder straps 346A and 346B first extend parallel to each other along both sides of the spine, forming two contact points (i.e., first contact points, such as two shoulder points) with the pet vest worn on the dog 32800±, and then cross each other to provide a third contact point at the intersection around the annular member 31716. The shoulder points are located on the shoulders of the dog 32800 (corresponding to the position of the dog's scapula, as shown in Figure 21), which allows for strong, stable, and secure support for the dog 32800 compared to existing transport cages or vests. According to this embodiment, the third contact point at the intersection around the annular member 31716 also allows for increased support for the dog 32800 and is safer for the dog 32800 in moving vehicles. Therefore, even if the dog 32800 is wearing an existing vest similar to the vest 317A shown in Figure 36A, the pet carrier 342 disclosed herein is still able to provide relatively robust, stable and safe support for the dog 32800 compared to existing transport cages or vests.Please refer to Figures 49, 49A, and 49B, which schematically illustrate a pet transportation system in use according to an embodiment of the present disclosure. In this embodiment, the combination of the straps of the pet carrier 342 and the strips or bars of the vest (as shown in Figure 36A) shown in Figure 23 is also used as an example to illustrate how the combination of the straps of the pet carrier 342 and the strips or bars of the vest provides support for a pet restrained in the box of the pet carrier 342 in a manner different from the embodiments of Figures 47 and 48. To avoid obscuring the present disclosure, structures or components of the pet carrier 342 or vest that are not essential to the strap / strip combination of the present disclosure may not be shown in the figures and are not redundantly described. As shown in the figures, Figure 49 is a schematic top view illustrating a pet (such as a dog 33000) wearing the vest of Figure 36A, restrained within the box section of the pet carrier 342 of Figure 23, while Figures 49A and 49B are schematic side views of Figure 49, showing the dog 33000 standing and lying in the pet carrier 342, respectively. In this embodiment, shoulder straps 346A and 346B extend from slots 3424A and 3424B and are pulled upwards to extend along the corresponding two front legs of the dog 33000. Shoulder straps 346A and 346B extend from the underside and outside of shoulder straps 31710A and 31710B, through the gaps between the corresponding two shoulders of the dog 33000 and the corresponding two shoulder straps 31710A and 31710B of the vest worn on the dog 33000, and extend along shoulder straps 31710A and 31710B around the sides of the spine of the dog 33000. Shoulder straps 346A and 346B further extend along the central strip of the vest, cross each other and extend through the annular member 31716, and then latch to clips 3482B and 3482A via corresponding tongues 3462A and 3462B, thereby connecting to the corresponding carrier straps 348B and 348A of the pet carrier 342.More specifically, since shoulder straps 346A and 346B cross at the position of the annular member 31716, shoulder strap 346A can be connected to carrier strap 348B by engaging the tongue member 3462A in the buckle 3482B, while shoulder strap 346B can be connected to carrier strap 348A by engaging the tongue member 3462B in the buckle 3482A. The user (or pet owner) can pull the adjustment strap 3764 to adjust its tightness, and after adjustment, the adjustment strap 3764 is secured with the positioning buckle 3726. Since the adjustment strap 3764 is connected to two carrying straps (i.e., carrying straps 376A and 376B shown in Figures 26A and 26B), which are the same straps as the corresponding shoulder straps 346A and 346B of the pet carrier 342, the tightness of shoulder straps 346A and 346B can be adjusted by pulling the adjustment strap 3764. To accommodate the body size of dog 33000. Similarly, in this embodiment, the shoulder point is located at the shoulder of dog 33000 (corresponding to the position of the dog's scapula, as shown in Figure 21), which allows for sturdy, stable, and secure support for dog 33000 compared to existing transport cages or vests. According to this embodiment, the third contact point at the intersection around the annular member 31716 also allows for increased support for dog 33000 and is safer for dog 33000 in moving vehicles. Therefore, even if dog 33000 is wearing an existing vest similar to vest 317A as shown in Figure 36A, the pet carrier 342 of this disclosure is still able to provide relatively sturdy, stable, and secure support for dog 33000 compared to existing transport cages or vests. Please refer to Figures 50 and 51, which schematically illustrate a pet travel system in use according to an embodiment of this disclosure. In this embodiment, taking the pet carrier 3112 shown in FIG. 30 and the vest (vest 3170 shown in FIG. 36C) as examples, we illustrate how the combination of the straps of the pet carrier 3112 and the strips or bars of the vest provides support for a pet restrained in the box of the pet carrier 3112. To avoid obscuring this disclosure, structures or components of the pet carrier 3112 or vest that are not essential to the strap / strip combination of this disclosure may not be shown in the figures and are not redundantly described. As shown, FIG. 50 is a schematic top view showing a pet (such as a dog 33100) wearing the vest of FIG. 36C restrained in the box of the pet carrier 3112 of FIG. 30, while FIG. 51 is a schematic side view of FIG. 50.In this embodiment, the extension segment 3116 of the Y-shaped strap can extend from the slot (i.e., slot 31124 shown in FIG. 30) and can be pulled upward to extend along the chest of the dog 33100, wherein two separate shoulder segments 31164A and 31164B (which are connected to the extension segment 3116 via connecting portions 31162 extending from them) extend along the corresponding two shoulder straps 31730A and 31730B of the vest worn on the dog 33100 and pass through the corresponding loops formed by webbing 31731A and 31731B. The two shoulder segments 31164A and 31164B cross each other and extend through the ring member 31716, and are then latched to the buckles 31182B and 31182A by corresponding tongues, thereby connecting to the corresponding carrier straps 3118B and 3118A of the pet carrier 3112. More specifically, since shoulder segments 31164A and 31164B intersect at the position of annular member 31716, shoulder segment 31164A can be connected to carrying strap 3118B by engaging with buckle 31182B via a tongue-shaped member, while shoulder segment 31164B can be connected to carrying strap 3118A by engaging with buckle 31182A via a tongue-shaped member. Preferably, in this embodiment, for a relatively large dog 33100, carrying straps 3118A and 3118B are connected to adjusting straps 31186A and 31186B respectively via ladder locks 31184A and 31184B. In this embodiment, connecting portion 31162 can be used as an intersection point on the chest plane of the dog 33100 (e.g., intersection point S31 as a third contact point). Shoulder segments 31164A and 31164B form a second intersection point S32 (i.e., another third contact point) on the back plane of the dog 33100. Therefore, even though shoulder segments 31164A and 31164B are not constrained by any vest straps used to support the dog 33100, and the two intersection points S31, S32 are located in different planes relative to the dog 33100 (i.e., one around the chest and the other around the back), stable support forces can still be applied to the dog 33100 from different planes. In this way, compared to existing transport cages or vests, this disclosure allows for relatively robust, stable, and secure support for the dog 33100. Please refer to Figures 52 and 53, which schematically illustrate a pet transportation system in use according to an embodiment of this disclosure.In this embodiment, the combination of the straps of the pet carrier 3132 shown in FIG. 32 and the vest with webbing attached to the shoulder straps and its back straps (similar to the vest shown in FIG. 36B, wherein the fixing direction of the webbing on the shoulder straps and back straps is different from the original fixing direction of the webbing in FIG. 36B) is used as an example to illustrate how the combination of the straps of the pet carrier 3132 and the straps or strips of the vest provides support for a pet restrained in the box of the pet carrier 3132. To avoid obscuring this disclosure, structures or components of the pet carrier 3132 or vest that are not essential to the combination of straps / strips of this disclosure may not be shown in the figures and are not redundantly described. As shown, FIG. 52 is a schematic top view showing a pet (such as a dog 33300) wearing a vest (similar to that shown in FIG. 36B) and restrained in the box of the pet carrier 3132 of FIG. 32, while FIG. 53 is a schematic side view of FIG. 52. In this embodiment, fastening straps 3136A and 3136B of the pet carrier 3132, spaced apart by a predetermined interval, extend from the seat, pass through the bottom of the box portion of the pet carrier 3132 and an interface along a long side, and latch to fastening straps 3138A and 3138B fixed to opposite sides of the box portion of the pet carrier 3132. Fastening strap 3136A is pulled to pass through a loop formed by the vest webbing 31721A and the right shoulder strap, and then through a loop formed by the vest webbing 31721B and the left shoulder strap. Fastening strap 3136B is pulled upwards to pass through a loop formed by the vest webbing 31722A and the right back strap, and then through a loop formed by the vest webbing 31722B and the left back strap. The fastening straps 3136A and 3136B can therefore extend parallel to each other to be connected to the corresponding fixing straps 3138A and 3138B by engaging the corresponding tongues 31362A and 31362B in the clips 31382A and 31382B. The user (or pet owner) can pull the corresponding adjusting straps 31364A and 31364B to adjust their tightness, and after adjustment, secure the adjusting straps 31364A and 31364B with the corresponding positioning buckles (not shown). Since the corresponding adjusting straps 31364A and 31364B are the same straps as the corresponding fastening straps 3136A and 3136B of the pet carrier 3132, the tightness of the fastening strap 3136 can be adjusted by pulling the corresponding adjusting straps 31364A and 31364B to accommodate the size of the dog 33300.In this embodiment, the fastening straps 3136A and 3136B pass parallel to each other from one long side to the opposite long side of the pet carrier 3132, and contact the shoulder straps and back straps along their length, thereby forming two parallel linear contact areas. These include one linear contact area passing through the shoulders of the dog 33300 (corresponding to the location of the dog's scapula, as shown in Figure 21), and another linear contact area passing through the mid-back of the dog 33300 (corresponding to the sides of the thoracic vertebrae, as shown in Figure 21). Compared to existing transport cages or vests, the two linear contact areas, particularly the area passing through the two shoulders of the dog 33300, allow for relatively firm, stable, and secure support for the dog 33300. Furthermore, the parallel construction of the fastening straps 3136A and 3136B allows for a relatively large range of motion for the dog 33300, avoiding excessive restriction that could cause discomfort. Please refer to Figures 54 and 55, which schematically illustrate a pet transportation system in use according to an embodiment of the present disclosure. In this embodiment, the combination of the straps of the pet carrier 3132 and the vest (vest 317B as shown in Figure 36B) shown in Figure 32 is also used as an example to illustrate how the combination of the straps of the pet carrier 3132 and the strips or bars of the vest provides support for a pet restrained within the cage of the pet carrier 3132 in a manner different from the embodiments of Figures 52 and 53. To avoid obscuring the present disclosure, structures or components of the pet carrier 3132 or vest that are not essential to the strap / strip combination of the present disclosure may not be shown in the figures and are not described redundantly. As shown in the figures, Figure 54 is a schematic top view of a pet (such as a dog 33500) wearing a vest (similar to the vest shown in Figure 36B, wherein the fixing direction of the webbing on the shoulder straps and back straps is different from the original fixing direction of the webbing in Figure 36B) and restrained in the box of the pet carrier 3132 of Figure 32, while Figure 55 is a schematic side view of Figure 54. In this embodiment, fastening straps 3136A and 3136B of the pet carrier 3132, spaced apart from each other by a predetermined interval, extend from the seat, pass through the bottom of the box portion of the pet carrier 3132 and an interface of a long side, and latch to corresponding fastening straps 3138B and 3138A fixed to opposite sides of the box portion of the pet carrier 3132. More specifically, fastening strap 3136A is pulled up to pass through a loop formed by the vest webbing 31721A and the right shoulder strap, and then through a loop formed by the vest webbing 31722B and the left back strap.The fastening strap 3136B is pulled up to pass through the loop formed by the vest's webbing 31722A and the right back strap, and then through the loop formed by the vest's webbing 31721B and the left shoulder strap. In other words, the fastening straps 3136A and 3136B cross each other at a position on the central strap of the vest to form a crossing point S31 on the back of the dog 33300 (corresponding to the position on the spine). The fastening straps 3136A and 3136B are connected to the corresponding fastening straps 3138B and 3138A by corresponding tongues 31362A and 31362B engaging in the buckles 31382B and 31382A. Similarly, the user (or pet owner) can pull the corresponding adjustment straps 31364A and 31364B to adjust their tightness, and after adjustment, secure the adjustment straps 31364A and 31364B with the corresponding positioning buckles (not shown in the figure). Since the corresponding adjustment straps 31364A and 31364B are the same straps as the corresponding fastening straps 3136A and 3136B of the pet carrier 3132, the tightness of the fastening straps 3136A and 3136B can be adjusted by pulling the corresponding adjustment straps 31364A and 31364B to fit the size of the dog 33500. In this embodiment, the fastening strap 3136A forms a first contact point (i.e., a shoulder point) with the vest worn on the dog 33500 ± by passing through a loop formed by the vest's webbing 31721A and the right shoulder strap, and forms a second contact point (e.g., a back point) by passing through a loop formed by the vest's webbing 31722B and the left back strap. Similarly, the fastening strap 3136B forms another second contact point (i.e., another back point) by passing through a loop formed by the vest's webbing 31722A and the right back strap, and forms another first contact point (e.g., another shoulder point) by passing through a loop formed by the vest's webbing 31721B and the left shoulder strap. The intersection of the fastening straps 3136A and 3136B provides a third contact point (i.e., intersection S31) at the intersection of the central straps. Two shoulder points are located at the corresponding shoulders of the dog 33500 (corresponding to the position of the dog's scapula, as shown in Figure 21), which allows for robust, stable, and secure support for the dog 33500 compared to existing transport cages or vests. The intersection S31 according to this embodiment also allows for increased support for the dog 33500. This five-point support (e.g., two shoulder points, two back points, and one intersection point) allows for safer support for the dog 33500 in a moving vehicle. Please refer to Figures 56 and 57, which schematically illustrate a pet transportation system in use according to an embodiment of this disclosure.In this embodiment, taking the pet carrier 342 shown in FIG. 23 and the vest (vest 317E shown in FIG. 36E) as examples, we illustrate how the combination of the straps of the pet carrier 342 and the strips or bars of the vest provides support for a pet restrained in the box of the pet carrier 342. To avoid obscuring this disclosure, structures or components of the pet carrier 342 or vest that are not essential to the strap / strip combination of this disclosure may not be shown in the figures and are not redundantly described. As shown, FIG. 56 is a schematic top view showing a pet (e.g., a dog 33700) wearing the vest of FIG. 36E and restrained in the box of the pet carrier 342 of FIG. 23, while FIG. 57 is a schematic side view of FIG. 56. In this embodiment, shoulder straps 346A and 346B extend from slots 3424A and 3424B, are pulled upward to extend along the respective two front legs of the dog 33700, pass through the loop formed by the respective webbing 31751A and 31751B of the vest and the chest pad 3175 from the underside of the strip, extend along the body of the dog 33700 to cross each other at the back of the dog 33700, then pass through the loop formed by the respective webbing 31752B and 31752A of the vest and the back pad 3175, and are latched to clips 3482B and 3482A with the respective tongues 3462A and 3462B, thereby connecting to the respective carrier straps 348B and 348A of the pet carrier 342. More specifically, due to the intersection of shoulder straps 346A and 346B at intersection point S31, shoulder strap 346A can be connected to the bag strap 348B by the tongue 3462A engaging in the buckle 3482B, while shoulder strap 346B can be connected to the bag strap 348A by the tongue 3462B engaging in the buckle 3482A. Preferably, shoulder straps 346A and 346B can pass through the back pad 3175 of the vest, on which a loop is formed by the webbing 31755 and the back pad 3175, and cross each other in the loop to prevent the straps from moving easily. Similarly, the user (or pet owner) can pull the adjustment strap 3764 to adjust its tightness, and then secure the adjustment strap 3764 with the positioning buckle 3726. Since the adjustment strap 3764 is connected to two harnesses (i.e., harnesses 376A and 376B shown in Figures 26A and 26B), which are the same straps as the corresponding shoulder straps 346A and 346B of the pet carrier 342, the tightness of the shoulder straps 346A and 346B can be adjusted by pulling the adjustment strap 3764 to fit the size of the dog 33700.As shown in Figures 56 and 57, in this embodiment, the two shoulder straps 346A and 346B contact the vest at four points, forming four contact points. These four contact points include two shoulder points (i.e., the first contact point located on the shoulder, corresponding to the dog's scapula position, as shown in Figure 21) and two abdominal points located around the lower abdomen of the dog 33700 (also referred to as the "fourth contact point" between the shoulder straps and the pet vest). Furthermore, the crossing of straps 346A and 346B at intersection S31 allows for additional support for the dog 33700. This five-point support configuration allows for safer support of the dog 33700 in a moving vehicle. Please refer to Figures 58 and 59, which schematically illustrate a pet mobility system in use according to an embodiment of this disclosure. In this embodiment, taking the pet carrier 342 and vest (vest 317E as shown in Figure 36E) as examples, we illustrate how the combination of the straps of the pet carrier 342 and the strips or bars of the vest provides support for a pet restrained in the box of the pet carrier 342 in a manner different from the embodiments of Figures 56 and 57. To avoid obscuring this disclosure, structures or components of the pet carrier 342 or vest that are not essential to the strap / strip combination of this disclosure may not be shown in the figures and are not redundantly described. As shown, Figure 58 is a schematic top view illustrating a pet (e.g., a dog 33900) wearing the vest of Figure 36E and restrained in the box of the pet carrier 342 of Figure 23, while Figure 59 is a schematic side view of Figure 58. In this embodiment, shoulder straps 346A and 346B can extend from slots 3424A and 3424B, pull upward to extend along the respective two front legs of the dog 33900, and pass from the underside of the strip through the loop formed by the respective webbing 31751A and 31751B of the vest and the chest pad 3175. Shoulder straps 346A and 346B can extend longitudinally along both sides of the dog 33700's body and pass through the loop formed by the respective webbing 31752A and 31752B of the vest and the chest pad 3175, and are latched to clips 3482A and 3482B with corresponding tongues 3462A and 3462B, thereby connecting to the respective carrier straps 348A and 348B of the pet carrier 342.Similarly, the user (or pet owner) can pull the adjustment strap 3764 to adjust its tightness, and after adjustment, secure the adjustment strap 3764 with the positioning buckle 3726. Since the adjustment strap 3764 is connected to two harnesses (i.e., harnesses 376A and 376B shown in Figures 26A and 26B), which are the same straps as the corresponding shoulder straps 346A and 346B of the pet carrier 342, the tightness of the shoulder straps 346A and 346B can be adjusted by pulling the adjustment strap 3764 to accommodate the dog 33900's body shape. In this embodiment, the shoulder straps 346A and 346B extend in parallel, thus there is no intersection point compared to that shown in Figures 56 and 57. However, in this way, the four contact points (especially the two shoulder points) still allow for relatively strong, stable, and secure support for the dog 33900 compared to existing transport cages or vests. It should be noted that the "shoulder strap" in the third aspect of this disclosure is similar to the "restraint webbing" in the second aspect of this disclosure, and the "fastening strap" can also be considered as another type of restraint webbing. That is, the pet carriers of the embodiments of the third aspect may include restraint devices having restraint webbing. The restraint webbing may include shoulder straps and / or fastening straps, threaded through slots in the bottom of the pet carrier to engage with corresponding connectors (e.g., corresponding structures of pet harnesses, vests, etc.) for wearable items for pets, thereby confining the pet within the accommodating space formed by the carrier's box (also referred to as the "box"). Optionally, the box (e.g., the restraint device) may also include box straps extending from corresponding other slots in the bottom of the box, and further, shoulder straps may be connected to the box straps to restrain the pet within the box. Furthermore, the "loops" formed by the shoulder straps, back straps, and central straps with the webbing of the vest in the third aspect of this disclosure can correspond to the "connectors" of the pet vest in the second aspect of this disclosure. Pet carrier and vehicle baseless attachment: Although the above figures relate to pet mobility devices or systems that include a base for attaching the pet carrier to a vehicle, it should be noted that the pet carrier or pet mobility system shown can be attached to a vehicle without a base. Those skilled in the art will understand that the pet carrier or pet mobility system according to this disclosure can be attached to a vehicle via an integrated anchoring system, or in combination with a top strap anchoring system and an integrated anchoring system (as shown in Figure 60 or Figure 61), or attached via the vehicle's seatbelt (as shown in Figure 62). Pet mobility devices with a rigid anchoring system include a storage compartment for storing the anchor.Therefore, the anchor may not protrude outward from the outward facing side of the seat housing. The shape of the storage compartment may correspond to the shape of the anchor. The dimensions of the storage compartment may also be set to be substantially similar to the dimensions of the anchor. The rigid anchoring system may be telescopically adjustable, formed along the side of the seat and shifting between a storage position and an operating position. When the rigid anchoring system is in the storage position, it is fully positioned within the storage compartment space of the seat. In some embodiments, the rigid anchoring system further includes a cross member to adjust the distance between the anchors. When the rigid anchoring system is in the operating position, the anchor can be protruded from the seat housing by sliding or rotating via a release button for mounting to a vehicle seat. The seat also includes a foot located under the vehicle or positioned in the space between the anchors. The foot can move between an extended mode and a retracted mode. In the extended mode, the foot extends beyond the outer surface of the seat. The foot may be coupled to at least one of the anchors such that movement of one or both anchors can cause the foot to move relative to the pet vehicle and one or both anchors. The movement of the anchors may be different from or opposite to the movement of the foot. For example, when the anchor rotates counterclockwise, the foot will rotate clockwise, and vice versa. Figure 60 schematically illustrates a pet carrier 34100 with a combination of soft latches and rigid latch systems for attachment to a vehicle. As shown, the soft latch is a third anchor point in addition to an integrated rigid anchoring system (such as ISOFIX connector 34120, which forms one or more anchor points). The soft latch system includes one or more anchors that can be positioned diagonally relative to the rigid latch system. The soft latch system can be integrated with a rigid latch system disposed on an opposing surface of the seat. In some embodiments, the rigid latch system also includes a rotatable anchor and an extendable foot as described above. The soft latch system includes a top tether strap and at least one anchor. The top tether strap is a section of webbing that serves as a top tether strap and is attached to the rear of the pet carrier 34100 via hooks 34110 located at its ends. The top tether strap can be tightened to secure it to the vehicle seat via the hooks 34110. Figure 61 schematically illustrates a pet carrier 34200 with a combination of soft and rigid latch systems for attachment to a vehicle. The soft and rigid latch systems can be located on the same surface of the seat. The rigid latch system may also include rotatable anchors and extendable feet as described above. As shown, the pet carrier 34200 includes a section of webbing attached to the rear of the pet carrier 34200 via an ISOFIX connector 34210 for attachment to the vehicle.In addition, the pet carrier 34200 also includes a rigid frame 34220 forming an ISOFIX, which has two connectors for attachment to the vehicle.
