FIG5 illustrates a UU cross-sectional view of FIG4 . FIG6 to FIG8 illustrate perspective views of the carrier 100 and LATCH structure 300 in FIG1 from different perspectives. FIG9 and FIG10 illustrate alternative embodiments of the connection assembly 35 in FIG8 . FIG11 and FIG12 illustrate perspective views of the top tether 200 in FIG1 from different perspectives. Referring to FIG1 , the carrier securing mechanism 1000 may include the carrier 100, the top tether 200, and the LATCH structure 300. The seat 900 is, for example, a vehicle seat and includes a seat cushion 91, a backrest 92, and a headrest 93. In some embodiments, the headrest 93 has an insertion rod 931 that inserts into the backrest 92 from the top. The carrier 100 may be, for example, but is not limited to, an infant carrier (e.g., an infant carrier) or a pet carrier (e.g., a pet carrier or pet crate). In FIG1 , the carrier 100 is specifically described using a pet crate as an example, with the carrier 100 forming a storage space for a pet. Referring to FIG2 , FIG4 , and FIG5 , in some embodiments, the LATCH structure 300 includes a connector 31 that can connect to a connection point on the seat 900, such as the ISOFIX structure 94. Furthermore, the carrier 100 is secured to the ISOFIX structure 94 of the seat 900 via the LATCH structure 300. The connection between the LATCH structure 300 and the ISOFIX structure 94 prevents the carrier 100 from falling off the seat 900 during emergency braking. In some embodiments, the LATCH structure 300 can be detachably connected to the carrier 100. In some embodiments, the LATCH structure is, for example, non-detachably connected to the carrier 100. Referring to Figures 6 through 8 , an exemplary embodiment of a LATCH structure 300 is shown, which is detachably connected to the carrier 100. Specifically, the LATCH structure 300 includes a webbing 32 connected to a connector 31. The webbing 32 is detachably attached to the carrier 100, allowing the LATCH structure 300 to be separated from the carrier 100. Continuing with Figures 6 through 8 , to facilitate the connection of the webbing 32 to the carrier 100, the webbing 32 may include a first webbing segment 321 and a second webbing segment 322.The first end of the first webbing segment 321 and the first end of the second webbing segment 322 are connected, and the first ends of the first webbing segment 321 and the second webbing segment 322 are directly or indirectly connected to the connector 31. The second ends of the first webbing segment 321 and the second ends of the second webbing segment 322 are detachably connected, so that the first webbing segment 321 and the second webbing segment 322 define an annular structure (not numbered in the figure) that fits over the carrier 100. When the first end of the third webbing segment 321 and the first end of the second webbing segment 322 are separated, the annular structure opens, allowing the carrier 100 to be easily separated from the LATCH structure 300. Referring to FIG. 7 , in some embodiments, at least one of the first webbing segment 321 and the second webbing segment 322 may be provided with an adjuster 324. Alternatively, in some embodiments, the first end of the first webbing segment 321 is connected to the second webbing segment 322 via the adjuster 324, and the first end of the second webbing segment 322 is connected to the connector 31. By providing the adjuster 324, the length of the first webbing segment 321 and / or the second webbing segment 322 can be changed, thereby adjusting the size of the annular structure defined by the first webbing segment 321 and the second webbing segment 322, allowing the annular structure to adapt to carriers 100 of varying sizes. Referring to Figures 6 and 8, in some embodiments, the second end of the first webbing segment 321 and the second end of the second webbing segment 322 are detachably connected via a connecting assembly 35. In some embodiments, the connecting assembly 35 is, for example, a magnetic fastening mechanism. More specifically, the magnetic fastening mechanism includes, for example, a first connecting member 351 and a second connecting member 352. The first connecting member 351 is, for example, a male buckle, and the second connecting member 352 is, for example, a female buckle. The first connecting member 351 is connected to one of the first webbing segment 321 and the second webbing segment 322, while the second connecting member 352 is connected to the other of the first webbing segment 321 and the second webbing segment 322. The first connecting member 351 has a protruding structure 3511, and the second connecting member 352 includes a cavity 3520, which is configured to engage with the protruding structure 3511 of the first connecting member 351. The protruding structure 3511 is provided with a groove 3510. The second connecting member 352 also includes a locking mechanism 3521, which engages with the groove 3510 within the cavity 3520. The groove 3510 can be a partially annular or fully annular structure. Continuing with Figures 6 and 8, in some embodiments, the second connecting member 352 is further provided with a release member 353, which is operably connected to the locking mechanism 3521.Specifically, the locking member 353 may be a release strap. When the release member 353 is pulled, it disengages the locking mechanism 3521 from the groove 3510 of the first connector 351, further separating the first connector 351 from the second connector 352. In some embodiments, the locking mechanism 3521 may include a magnetic device. The magnetic device may be provided on the first connector 351 (e.g., the protruding structure 3511). The magnetic devices of the first connector 351 and the locking mechanism 3521 attract each other, further strengthening the fastening between the first connector 351 and the second connector 352. Referring to Figures 6 and 7, when the first connector 351 and the second connector 352 of the magnetic fastening mechanism 35 are fastened, the webbing 32 wraps around the carrier 100. The magnetic fastening mechanism 35 is located on a surface of the carrier 100 not obstructed by the seat 900 (e.g., the front 11 or top 12 of the carrier 100). The first end of the first webbing segment 321, for example, extends from the top surface 12 to the back surface 13 of the carrier 100, and the first end of the second webbing segment 322, for example, extends from the bottom surface 14 of the carrier 100 to the back surface 13. Referring to Figure 8 , when the first connector 351 and the second connector 352 of the magnetic fastening mechanism 35 are separated, the carrier 100 and the LATCH structure 300 can be easily separated. In some embodiments, the surface of the carrier 100 may also be provided with a guide structure for guiding the webbing 32. The guide structure may, for example, include a C-shaped open groove provided on the surface of the carrier 100. Of course, the embodiment of the connection assembly 35 is not limited to the above examples; any suitable detachable connection structure may be employed. Figures 9 and 10 illustrate some variations of the connection assembly 35. In the variation of the connecting assembly 35 shown in FIG9 , the connecting assembly 35 includes a third connecting member 354 and a fourth connecting member 358. The fourth connecting member 358 is connected to one of the first and second webbing segments 321 and 322, while the third connecting member 354 is connected to the other of the first and second webbing segments 321 and 322. The fourth connecting member 358 is, for example, a male buckle, while the third connecting member 354 is, for example, a female buckle. The male buckle can be inserted into the female buckle. The third connecting member 358 is provided with a locking hole 3580. The first connecting member 354 includes a locking cavity 3540, which contains a locking member (not shown). When the fourth connecting member 358 and the second connecting member 354 are connected, the locking hole 3580 is located within the locking cavity 3540 and engages with the locking member. The second connecting member 354 also includes a release member 355, which is operably connected to the locking member.When the release member 355 is pressed, the locking member is driven out of the lock hole 3580, allowing the fourth connector 358 to be pulled away from the third connector 354. In the variant of the connection assembly 35 shown in FIG10 , the connection assembly 35 includes a fifth connector 356 and a sixth connector 357. The fifth connector 356 and the sixth connector 357 may be hook-and-loop fasteners. The fifth connector 356 and the sixth connector 357 may be sewn to the first webbing segment 321 and the second webbing segment 322, respectively. Referring again to FIG1 , the top tether 200 is connected to the carrier 100 via at least one connection assembly 400. The top tether 200 is also provided with an anchor 23 that can connect to an anchor structure within the vehicle to further secure the carrier 100 to the seat 900. Referring to FIG. 3 , in some embodiments, an anchor structure 95 is provided on the back of the backrest 92. The anchor structure 95 is configured to detachably connect to the anchor 23. Referring to FIG. 1 and FIG. 2 , the anchor 23 extends rearward from the upper portion of the backrest 92 and then connects to the anchor structure 95. In some embodiments, the anchor 23 can pass between two insertion rods 931 of the headrest 93. This allows the top tether 200 to effectively prevent the vehicle 100 from tipping forward during emergency braking. Referring to FIG. 3 , in some embodiments, the anchor structure 95 can include, for example, a recess 950 and a connecting rod 951 mounted therein. The anchor 23 can include, for example, a hook that can be hooked onto the connecting rod 951. In some embodiments, the anchor structure 95 can be located behind the seat 900, for example, on a vehicle wall. Of course, the anchor 23 and the anchor structure 95 can also adopt any other suitable structures. For example, in some unillustrated embodiments, at least one of the two insertion rods 931 of the headrest 93 can serve as an anchoring structure, and the anchor 23 can be connected to the insertion rod 931. For example, the anchor 23 can be a strap that is tied to one or both insertion rods 931. Referring again to FIG1 , an exemplary embodiment of a connection assembly 400 is shown. In some embodiments, the connection assembly 400 includes a connector 41 and a locator 42. The connector 41 is connected to the top strap 200, and the locator 42 is connected to the carrier 100. The connector 41 and the locator 42 are detachably connected. In some embodiments, one of the connector 41 and the locator 42 can be a buckle, and the other can be a ring. The connector 41 can be hooked to the ring. In this embodiment, the connector 41 is, for example, a buckle, and the locator 42 is a ring.In some embodiments, the connecting buckle includes a connecting ring 411, a pivot 412, a hook 413, and a locking arm 414. The connecting ring 411 is connected to the webbing 202, which can be connected to the top strap 200. The hook 413 is pivotally connected to the connecting ring 411 via the pivot 412. The hook body 413 has an installation opening 4130. The locking arm 414 is connected to the hook body 413 and can open or close the installation opening 4130. The buckle is connected to the webbing 101, which can be connected to the carrier 100. The buckle can enter the hook body 413 through the installation opening 4130 to hook with the hook body 413. It should be noted that the embodiment of the connection assembly 400 is not limited to the above-described combination of connecting buckles and buckles. For example, the connector 41 and the locator 42 may adopt the structure of any two mating connectors in the connection assembly 35 (e.g., the first connector 351 and the second connector 352, or the fourth connector 358 and the third connector 354, or the fifth connector 356 and the sixth connector 357). Of course, any two mating connectors in the connection assembly 35 may also adopt the structure of the connector 41 and the locator 42 of the connection assembly 400 described above. Referring to FIG. 1 , in some embodiments, the top strap 200 is connected to the carrier 100 via two connection assemblies 400. The two locators 42 of the two connection assemblies 400 are disposed on the front face 11 of the carrier 100. In some embodiments, the two locators 42 are located at the same height. Of course, in some alternative embodiments, the top strap 200 may be connected to the carrier 100 via one, three, or more connection assemblies 400. The locators 42 of one or more connection assemblies 400 can, for example, be located on at least one of the front surface 11, top surface 12, back surface 13, bottom surface 14, or side surfaces 15 of the carrier 100. Continuing with FIG1 , in some embodiments, two locators 42 are located on the front surface 11 of the carrier 100 and are arranged symmetrically in a left-right row. In some embodiments, the two locators 42 can be closer to the bottom surface of the carrier 100. The sheet portion 22 covers a sufficiently large area of ​​the carrier 100 (particularly the front surface 11 of the carrier 100) to ensure that the tension exerted by the top tether 200 in the left-right direction is relatively even, thereby effectively preventing the carrier 100 from tipping forward. When there are at least two connection assemblies 400, the locators 42 of these connection assemblies 400 can be located at the same height on the carrier 100 or at different heights. In some embodiments, at least a portion of the positioners 42 are disposed at the same height of the carrier 100 .In some embodiments, the locators 42 are arranged bilaterally symmetrically at the same height. Referring to Figures 11 and 12 , an exemplary embodiment of a top tether 200 is shown. The top tether 200 may include a webbing portion 21 and a sheet portion 22. The webbing portion 21 extends from the sheet portion 22, the anchor 23 is connected to the webbing portion 21, and the connector 41 is connected to the sheet portion 22. In some embodiments, the sheet portion 22 is shaped like a triangle, with the webbing portion 21 extending from one corner of the sheet portion 22 and two connectors 41 connected to the other two corners of the sheet portion 22. In some embodiments, in addition to the two connectors 41 shown in Figures 11 and 12 , at least one connector 41 may be provided along at least one edge of the sheet portion 22, and a locator 42 corresponding to the at least one connector 41 may be provided on the carrier 100. Referring to Figure 1 , in some embodiments, the sheet portion 22 may cover at least a portion of the front of the carrier 100. In some embodiments, the sheet portion 22 can be made of nylon fabric or other high-strength fabric. Referring to FIG. 13 , in some embodiments, the sheet portion 22 can be made of mesh fabric. In some embodiments, the sheet portion 22 can be made of opaque fabric. Referring again to FIG. 11 and FIG. 12 , in some embodiments, the webbing portion 21 can be provided with an adjuster 24 for adjusting the length of the webbing portion 21 to tighten the top tether 200. In some unillustrated embodiments, the top tether 200 may not include the sheet portion 22. For example, if the top tether 200 has only one connector 41, the connector 41 and the anchor 23 can be connected by the same webbing. In some unillustrated embodiments, if the top tether 200 has two or more connectors 41, the top tether 200 can include at least two branch webbings connected to the same webbing portion 21, with the ends of each branch webbing connected to corresponding connectors 41. Second Embodiment: Figure 14 shows a perspective view of a carrier securing mechanism 1000 according to a second embodiment of the present invention installed on a seat 900. Figures 15 and 16 show perspective views of the top tether 200 in Figure 14 from different angles. Figure 17 shows a perspective view of the top tether 200 in Figure 15 in a stowed state. Figure 18 shows a perspective view of the carrier securing mechanism 1000 in Figure 14 installed on a seat 900, with the top tether 200 and carrier 100 separated. Compared to the first embodiment, this embodiment primarily modifies the structure of the top tether 200.Unless otherwise specified, the structure of the carrier securing mechanism 1000 in this embodiment may be similar to the description of the aforementioned first embodiment. Referring to Figures 14 to 16 , in this embodiment, the top tether 200 includes a webbing portion 21, a sheet portion 22, and a rod 25. One side 222 of the sheet portion 22 is connected to the rod 25, and two connectors 41 are connected to the other side 221, with the side 222 opposing the side 221. In some embodiments, the sheet portion 22 is rectangular, with the two connectors 41 located at either end of the side 221. A fixing portion 252 is provided on the rod 25. One end of the webbing portion 21 is connected to the fixing portion 252, and the other end of the webbing portion 21 is connected to the anchor 23. The webbing portion 21 may be provided with an adjuster 24 for adjusting the length of the webbing portion 21. In some embodiments, the fixing portion 252 may be a fixing ring connected to the rod 25. Referring to FIG. 14 , when the top tether 200 is connected to the locator 42 of the carrier 100 via the connector 41 and to the anchor structure 95 within the vehicle via the anchor 23, the rod 25 can rest against the backrest 92 or against the two side inserts 931 of the headrest 93. This allows the sheet portion 22 to fully expand, covering a larger area of ​​the carrier 100. In some embodiments, the rod 25 can be an elongated structure made of rubber, plastic, metal (e.g., iron), or other suitable materials. Other suitable materials include EPP or resilient wood. Continuing with FIG. 14 , in some embodiments, the two locators 42 are located on the front 11 of the carrier 100 and are arranged symmetrically. In some embodiments, the two locators 42 can be located closer to the bottom of the carrier 100. The fully extended sheet portion 22 covers a sufficiently large area of ​​the carrier 100 (particularly the front face 11 of the carrier 100), ensuring a relatively balanced tension from the top tether 200 in the left-right direction, effectively preventing the carrier 100 from tipping forward. Referring to Figures 15 to 17 , in some embodiments, the rod 25 has a hollow structure (not shown) and a hole 251 communicating with the hollow structure. An automatic retractor (not shown) may be disposed within the hollow structure. In some embodiments, the automatic retractor may include a retracting shaft and a coil spring connected to the retracting shaft. The side edge 222 of the sheet portion 22 extends into the hollow structure through the hole 251 and connects to the automatic retractor.Referring to FIG. 18 , when the top tether 200 needs to be removed from the seat 900, the connection between the connector 41 and the anchor 42 can be first disconnected. The coil spring of the automatic retractor then drives the retractor shaft to rotate. As the retractor shaft rotates, it automatically winds the sheet portion 22 around the retractor shaft, causing the sheet portion 22 to be stored within the hollow structure of the rod 25, placing the top tether 200 in the stowed state. Subsequently, the connection between the anchor 23 and the anchor structure 95 is disconnected, allowing the top tether 200 to be easily removed. In alternative embodiments, the number of connectors 41 provided on the side 221 of the sheet portion 22 is not limited to two. In some embodiments, three, four, or more connectors 41 may be provided on the side 221. In some alternative embodiments, the rod 25 may not have a hollow structure for receiving the sheet portion 22. For example, the side 222 of the sheet portion 22 may be sleeved onto the rod 25. In this case, the location of the connector 41 is not limited to the side edge 221. In some embodiments, one or more connectors 41 may be provided along the side edge 223 and / or the side edge 224 of the sheet portion 22. It should be noted that in some embodiments, the carrier securing mechanism 1000 may be configured with only the top tether 200 without the LATCH structure 300. Furthermore, in some embodiments, the carrier securing mechanism 1000 may be configured with only the LATCH structure 300 without the top tether 200. Third Embodiment: Figures 19 and 20 illustrate perspective views of the carrier securing mechanism 1000 according to a third embodiment of the present invention mounted on a seat 900 from different perspectives. Figure 21 illustrates a side view of the carrier securing mechanism 1000 and seat 900 in Figure 19. Figure 22 illustrates a rear view of the carrier securing mechanism 1000 and seat 900 in Figure 19. FIG23 shows a perspective view of the carrier securing mechanism 1000 and seat 900 in FIG19 , with the top tether 200 and LATCH structure 300 removed from the seat 900 and the carrier 100 placed on the seat 900. FIG24 shows a perspective view of the top tether 200 and LATCH structure 300 in FIG19 . Referring to FIG19 through FIG23 , the carrier securing mechanism 1000 may include the carrier 100, the top tether 200, and the LATCH structure 300. The carrier 100 may be placed on the seat cushion 91 of the seat 900, with the top tether 200 and the LATCH structure 300 working together to secure the carrier 100 to the seat 900. In some embodiments, the top tether 200 and the LATCH structure 300 may be referred to as a carrier restraint structure.Seat 900 is, for example, a vehicle seat and includes a seat cushion 91, a backrest 92, and a headrest 93. In some embodiments, headrest 93 has an insertion rod 931 that inserts into backrest 92 from the top. Referring to FIG. 21 , in some embodiments, a connection point is provided on the front of seat 900 for connecting to LATCH structure 300. In some embodiments, the connection point is a TSOFT X structure 94 located between the front of backrest 92 and seat cushion 91. Referring to FIG. 22 , in some embodiments, an anchor structure 95 is provided on the back of seat 900 for connecting to top tether 200. In some embodiments, anchor structure 95 is provided on the back of backrest 92. In some embodiments, anchor structure 95 may be provided outside of seat 900, for example, on a vehicle compartment wall and behind seat 900. Carrier 100 may be a pet carrier (e.g., a pet carrier or pet crate). In this embodiment, the carrier 100 is specifically described using a pet carrier as an example. The carrier 100 is formed with a storage space for a pet. Referring to Figures 21 to 23 , the top tether 200 is provided with an anchor 23, which can be detachably connected to the aforementioned anchor structure 95. Specifically, the anchor 23 extends rearward from the upper portion of the backrest 92 and then connects to the anchor structure 95. In some embodiments, the anchor 23 can pass between the two insertion rods 931 of the headrest 93. In some embodiments, the anchor 23 can include a hook, and the anchor structure 95 can include a recess 950 and a connecting rod 951 mounted in the recess 950. The hook of the anchor 23 can be hooked onto the connecting rod 951. Of course, the structures of the anchor structure 95 and the anchor 23 are not limited to the above example. For example, in some embodiments not shown, at least one of the two insertion rods 931 of the headrest 93 can serve as the anchor structure, and the anchor 23 can be connected to the insertion rod 931. For example, the anchor 23 can be a strap that can be tied to one or both of the insertion rods 931. Referring to Figures 21, 23, and 24, the LATCH structure 300 is connected to the top tether 200. The top tether 200 can extend from front to back along the bottom of the carrier 100 and detachably connect to a connection point on the seat 900 (more specifically, the ISOFIX structure 94) via the LATCH structure 300. As a result, the carrier 100 is restrained in the space defined by the top tether 200, the LATCH structure 300, and the backrest 92.In some embodiments, the LATCH structure 300 includes at least one connector 31 that can be removably connected to the ISOFIX structure 94. In this embodiment, the LATCH structure 300 includes two connectors 31, spaced apart from each other. Each connector 31 can be directly or indirectly connected to the top tether 200. In some embodiments, the LATCH structure 300 is removably connected to the top tether 200. When the carrier 100 needs to be secured to the seat 900, the LATCH structure 300 can first be connected to the ISOFIX structure 94 of the seat 900, and then the carrier 100 can be placed on the seat cushion 91 (the top tether 200 has a portion located between the carrier 100 and the seat cushion 91). Then, the anchor 23 is passed through the two rods 931 and connected to the anchor structure 95, thereby securing the carrier 100 to the seat 900. In this way, when the vehicle brakes suddenly, the vehicle 100 is less likely to fall from the seat 900, and the tendency of the vehicle 100 to tip forward can be effectively suppressed by the top tether 200. Referring to Figures 19 to 21 , in some embodiments, the top tether 200 may also be connected to the vehicle 100 via at least one connection assembly 400. This allows the top tether 200 to directly apply traction to the vehicle 100, further preventing the vehicle 100 from tipping forward. Furthermore, the connection assembly 400 helps limit the left-right movement of the vehicle 100 relative to the seat 900. Referring to Figures 23 and 24 , exemplary embodiments of the connection assembly 400 are shown. The connection assembly 400 includes a connector 41 and a retainer 42. The connector 41 is connected to the top tether 200, and the retainer 42 is connected to the vehicle 100. The connector 41 and retainer 42 are detachably connected. In some embodiments, one of the connector 41 and the locator 42 is a connecting buckle, and the other is a buckle. The connecting buckle can be hooked with the buckle. In this embodiment, for example, the connector 41 is a connecting buckle, and the locator 42 is a buckle. In some embodiments, the connecting buckle includes a connecting ring 411, a pivot 412, a hook 413, and a locking arm 414. The connecting ring 411 is connected to the connecting strap 202, which can be connected to the top strap 200. The hook 413 is pivotally connected to the connecting ring 411 via the pivot 412 and has a mounting opening 4130. The locking arm 414 is connected to the hook 413 and can open or close the mounting opening 4130. The buckle of the locator 42 is connected to the connecting strap 101, which can be connected to the carrier 100.The buckle can be inserted into the hook body 413 through the mounting opening 4130 to engage with the hook body 413. It should be noted that the embodiment of the connecting assembly 400 is not limited to the above-described combination of connecting buckles and buckles; any suitable detachable connection structure may be employed. Referring to Figures 23 and 24 , in some embodiments, the top tether 200 is connected to the carrier 100 via two connecting assemblies 400. The two locators 42 of the two connecting assemblies 400 are, for example, disposed on the front surface 11 of the carrier 100. In some embodiments, the two locators 42 are located at the same height. Of course, in some alternative embodiments, the top tether 200 may be connected to the carrier 100 via one, three, or more connecting assemblies 400. The locators 42 of one or more connecting assemblies 400 may, for example, be disposed on at least one of the front surface 11, top surface 12, back surface 13, bottom surface 14, or side surfaces 15 (see Figure 21) of the carrier 100. In this embodiment, the number of connectors 41 corresponds to the number of locators 42. In some embodiments, the number and position of connectors 41 and locators 42 can be set as needed. In some embodiments, the number of connectors 41 and locators 42 may not be one-to-one corresponding. In this case, the connectors 41 and locators 42 can be selectively connected. When the number of connection assemblies 400 is at least two, the locators 42 of these connection assemblies 400 can be located at the same height on the carrier 100 or at different heights. In some embodiments, at least some of the locators 42 are located at the same height on the carrier 100. In some embodiments, the locators 42 at the same height are arranged symmetrically. Referring to Figures 23 and 24, an exemplary embodiment of a top strap 200 is shown. The top strap 200 may include a webbing portion 21 and a sheet portion 22. The webbing portion 21 extends from the sheet portion 22, and the anchor 23 is connected to the webbing portion 21. The LATCH structure 300 is connected to the sheet portion 22. The connector 41 of the connection assembly 400 is connected to the sheet portion 22. In some embodiments, an adjuster 24 may be provided on the webbing portion 21 to adjust the length of the webbing portion 21 to tighten the top tether 200. In some embodiments, the sheet portion 22 may have a non-uniform width, for example, with the width direction of the sheet portion 22 aligned with the left-right direction in FIG. 23 .In some embodiments, the sheet portion 22 includes a first portion 2201 that covers the front face 11 of the carrier 100. This first portion 2201, for example, has a relatively wide width. This helps to balance the tension exerted by the top tie 200 in the left-right direction on the carrier 100, thereby preventing the carrier 100 from tipping forward. Referring to FIG. 24 , in this embodiment, two connectors 41 are connected to two side edges of the first portion 2201, corresponding to the two locators 42. In some embodiments, the sheet portion 22 includes a second portion 2202 connected between the first portion 2201 and the webbing portion 21. This second portion 2202 can be substantially triangular in shape, and the webbing portion 21 can be connected to the corner of the second portion 2202 that is away from the first portion 2201. In some embodiments, the sheet portion 22 may further include a first portion 2203 positioned between the floor 14 and the seat cushion 91 of the carrier 100, and a second portion 2203 positioned between the first portion 2201 and the LATCH structure 300. In some embodiments, the second portion 2203 may be generally rectangular, with the two connectors 31 of the LATCH structure 300 connected to the two corners of the second portion 2203 facing away from the first portion 2201. In some embodiments, the width of the third portion 2203 may be approximately equal to the distance between the two ISOFIX structures 94 of the seat 900. In some embodiments, the sheet portion 22 may be made of nylon fabric or other high-strength fabric. Referring to FIG. 24 , in some embodiments, the sheet portion 22 may include a mesh fabric. In some embodiments, the fabric of the sheet portion 22 may be made of opaque fabric. In some embodiments not shown, the two connectors 31 of the LATCH structure 300 may be connected to the sheet portion 22 via two connecting straps. In some unillustrated embodiments, the two connecting straps connecting the two connectors 31 to the sheet portion 22 are each provided with an adjuster, allowing the length of each strap to be adjusted independently. In some embodiments, when the two connecting straps are of sufficient length, the sheet portion 22 may not include the aforementioned second portion 2203. For example, the two connecting straps extend from two corners of the first portion 2201 away from the second portion 2202. When the carrier 100 is strapped to the seat 900, the two connecting straps are spaced apart and positioned between the bottom 14 of the carrier 100 and the seat cushion 91. In some embodiments, the sheet portion 22 may not include the aforementioned second portion 2202, and the webbing portion 21 may be a Y-shaped connecting strap directly connected to the first portion 2201. In some unillustrated embodiments, the top tether 200 may not include the sheet portion 22.In some embodiments, the top tether 200 may include a connecting strap with an anchor 23 located at one end of the connecting strap. The other end of the connecting strap is connected to a connector 31 of the LATCH structure 300. In some embodiments, a connector 41 is connected to the middle portion of the connecting strap. In some unillustrated embodiments, the top tether 200 may not include the sheet portion 22. The top tether 200 may, for example, include a Y-shaped connecting strap, such as a main connecting strap and two branch connecting straps connected to the main connecting strap. The anchor 23 is provided on the main connecting strap, and the ends of each branch connecting strap are respectively connected to the connector 31. In some embodiments, a connector 41 is provided on each branch connecting strap. Fourth Embodiment: Figures 25 and 26 show perspective views of a carrier securing mechanism 1000 according to a fourth embodiment of the present invention installed on a full seat 900 from different perspectives. Figure 27 shows a side view of the carrier securing mechanism 1000 and seat 900 shown in Figure 25. FIG28 shows a perspective view of the carrier securing mechanism 1000 and seat 900 in FIG25 , with the top tether 200 and LATCH structure 300 removed from the seat 900 and the carrier 100 placed on the seat 900, with the top tether 200 deployed. FIG29 shows a perspective view of the top tether 200 and LATCH structure 300 in FIG25 , with the top tether 200 deployed. FIG30 and FIG31 show perspective views of the top tether 200 and LATCH structure 300 in FIG29 from different perspectives, with the top tether 200 stowed. Compared to the third embodiment described above, this embodiment primarily modifies the structure of the top tether 200. Unless otherwise specified, the structure of the carrier securing mechanism 1000 in this embodiment can be referred to the description of the first embodiment. Referring to FIG27 through FIG29 , the top tether 200 includes a webbing portion 21, a sheet portion 22, a rod 25, and at least one extension strap 26. The sheet portion 22 is, for example, quadrilateral, more specifically, rectangular. One side 222 of the sheet portion 22 is connected to the rod 25. In some embodiments, the rod 25 may be an elongated structure made of rubber, plastic, metal (e.g., iron), or other suitable materials. Other suitable materials may include EPP or resilient wood. The rod 25 is provided with a fixing portion 252, for example, located in the middle of the rod 25. In some embodiments, the fixing portion 252 may be a fixing ring connected to the rod 25. One end of the webbing portion 21 is connected to the fixing portion 252, and the other end of the webbing portion 21 is connected to the anchor 23.In some embodiments, the webbing portion 21 may be provided with an adjuster 24 for adjusting the length of the webbing portion 21. In this embodiment, the top strap 200 includes two extension straps 26 spaced apart from each other. The two extension straps 26 are connected to the other side 221 of the sheet portion 22, with the side 222 opposing the side 221. In some embodiments, the two extension straps 26 are located at either end of the side 221. The LATCH structure 300 includes two connectors 31, each connected to the two extension straps 26. In some embodiments, each extension strap 26 may be directly connected to the sheet portion 22. Alternatively, in some unillustrated embodiments, each extension strap 26 may be indirectly connected to the sheet portion 22. In some unillustrated embodiments, the side 221 of the sheet portion 22 may be provided with a rod, for example, having a length substantially equal to that of the side 221, to support the side 221. In some embodiments, the rod has a certain degree of elastic deformation to adapt to the surface undulations of the vehicle 100. In some embodiments, one, two, or more rings may be provided on the side edge 221. An extension strap 26 selectively passes through one or more of the rings, and two connectors 31 are provided at each end of the extension strap 26. Referring to Figures 25 to 27 , in some embodiments, the top tether 200 is connected to the vehicle 100 via at least one connection assembly 400. The structure of each connection assembly 400 can be similar to that described in the second embodiment, for example, including a connector 41 and a locator 42. Referring to FIG. 28 , in some embodiments, the two locators 42 are located on the front face 11 of the carrier 100 and are arranged symmetrically. The sheet portion 22 is provided with two connectors 41, and the two connectors 41 are provided correspondingly to the two locators 42. As described in the third embodiment, in some embodiments, the number of connectors 41 and locators 42 may not be in a one-to-one correspondence. When the carrier 100 needs to be secured to the seat 900, the LATCH structure 300 can be first connected to the ISOFIX structure 94 of the seat 900. The carrier 100 is then placed on the seat cushion 91, with the extension strap 26 of the top tether 200 positioned between the carrier 100 and the seat cushion 91. Subsequently, each connector 41 is connected to the corresponding locator 42, and the anchor 23 is passed through the two insertion rods 931 and connected to the anchor structure 95. The carrier 100 is thus restrained on the seat 900. In some embodiments, when the carrier fixing mechanism 1000 is in use, the rod 25 can rest against the backrest 92 or against the two insertion rods 931 of the headrest 93.In some embodiments, the two positioners 42 can be closer to the bottom surface of the carrier 100. This allows the sheet portion 22 to cover a sufficiently large area of ​​the carrier 100 (particularly the front surface 11 of the carrier 100), ensuring a relatively balanced tension from the top tether 200 in the left and right directions, thereby better preventing the carrier 100 from tipping forward. Referring to FIG. 28 , in some embodiments, the rod 25 has a hollow structure (not shown) and a hole 251 communicating with the hollow structure. An automatic retractor (not shown) can be disposed within the hollow structure. In some embodiments, the automatic retractor can include a retracting shaft and a coil spring connected to the retracting shaft. The side edge 222 of the sheet portion 22 extends into the hollow structure through the hole 251 and connects to the automatic retractor. Referring to Figures 30 and 31 , when the top tether 200 and LATCH structure 300 are no longer in use, at least the sheet portion 22 located between the connector 41 and the rod 25 can be retracted into the hollow structure of the rod 25. To remove the top tether 200 and LATCH structure 300 from the seat 900, the connection between the anchor 23 and the anchor structure 95 (see Figure 22) can be first released. The coil spring of the automatic retractor within the rod 25 then drives the retractor shaft to rotate. As the retractor shaft rotates, it automatically winds the sheet portion 22 around the retractor shaft, causing it to be retracted into the hollow structure of the rod 25, placing the top tether 200 in the retracted position. The connection between the connector 41 and the retainer 42 can then be released, the carrier 100 can be removed, and finally, the connection between the connector 31 and the 1S0F1X structure 94 can be released. In some alternative embodiments, the rod 25 may not have a hollow structure for receiving the sheet portion 22. For example, the side 222 of the sheet portion 22 may be sleeved onto the rod 25. In some embodiments, the connector 41 and the corresponding connecting strap 202 may not be provided on the top tether 200, allowing the sheet portion 22 to be substantially completely retracted within the hollow structure of the rod 25. In some embodiments, the extension straps 26 may also be retracted within the hollow structure of the rod 25. Fifth Embodiment: Figures 32 and 33 show perspective views of a vehicle securing device 100A according to a fifth embodiment of the present invention in a deployed state from different perspectives. Figure 34 shows a perspective view of the vehicle securing device 100A in another deployed state. Figure 35 shows an elevation view of the vehicle securing device 100A in a collapsed state. Figure 36 shows an elevation view of the vehicle securing device 100A installed on a vehicle seat 900, with the vehicle securing device 100A in a collapsed state.Figure 37 shows an elevation view of a carrier 200A mounted on a vehicle seat 900 using the carrier anchor device 100A, with the carrier anchor device 100A in an unfolded state. Figure 38 shows a side view of the carrier anchor device 100A, carrier 200A, and vehicle seat 900 shown in Figure 37 . To facilitate understanding, the figures of this embodiment use arrow F to indicate the forward direction, arrow B to indicate the rearward direction, arrow L to indicate the left direction, and arrow R to indicate the right direction. These directional terms are intended solely to clarify the description of the various embodiments of the present invention and are not intended to unduly limit the scope of protection of the present invention. Referring to Figures 32 to 35 , the carrier anchor device 100A includes a base 1 and a stopper 2. A LATCH structure 13A is provided at one end of the base 1. This LATCH structure 13A can be connected to the vehicle seat 900, more specifically, to the ISOFIX structure 912 (see Figure 36 ). The other end of the base 1 is pivotally connected to the stopper 2 via a pivot portion 12A. The stopper 2 can pivot relative to the base 1 about the pivot portion 12A, allowing the carrier securing device 100A to switch between an in-use state and a folded state. Referring to Figures 32 to 34 , in the in-use state, the stopper 2 rotates relative to the base 1, causing the carrier securing device 100A to unfold and extend upward relative to the base 1. In some embodiments, when the carrier securing device 100A is in the in-use state, the angle a formed by the stopper 2 and the base 1 is approximately 90 degrees. In some embodiments, when the carrier securing device 100A is in the in-use state, the angle a can be between 90 and 180 degrees. In some embodiments, when the carrier securing device 100A is in the in-use state, the angle a can be less than 90 degrees. Referring to Figure 35 , in some embodiments, when the carrier securing device 100A is in the folded state, the stopper 2 pivots to a position substantially parallel to the base 1. In this state, the carrier securing device 100A is compact and easily stowed. In some embodiments, when the carrier securing device 100A is in the folded state, the stopper 2 may be prevented from being parallel to the base 1 due to interference from other structures, and the stopper 2 may still form an angle α greater than 0 degrees with the base 1. This folded state is also within the scope of protection of this embodiment. In some embodiments, the pivot portion 12A includes a rotation locking mechanism (not shown) that can lock the relative position of the stopper 2 and the base 1, thereby maintaining the carrier securing device 100A in the folded state or a certain unfolded state. In some embodiments, the rotation locking mechanism can have a locked state and a released state. When the rotation locking mechanism is in the locked state, the stopper 2 and the base 1 cannot rotate relative to each other.When the rotation locking mechanism is in the unlocked state, the stopper 2 and the base 1 can rotate relative to each other. Referring to Figures 36 to 38 , when the vehicle securing device 100A is in use, the base 1 is supported on the seat cushion 91 of the vehicle seat 900, the LATCH structure 13A is connected to the ISOFIX structure 912 of the vehicle seat 900, and the stopper 2 is pivoted to a suitable position away from the backrest 92 of the vehicle seat 900. The vehicle 200A can then be placed on the base 1, positioned between the stopper 2 and the backrest 92. This vehicle securing device 100A positions the vehicle 200A between the backrest 92 and the stopper 2, preventing the vehicle 200A from sliding forward and backward on the vehicle seat 900. In some embodiments, before placing the carrier 200A on the base 1, the stopper 2 can be pivoted to a larger angle relative to the base 1 to facilitate placement of the carrier 200A. After placing the carrier 200A on the base 1, the stopper 2 can be rotated to clamp the carrier 200A between the backrest 92 and the stopper 2. When the carrier 200A is clamped, the front side 201A of the carrier 200A abuts the stopper 2, and the rear side 202A of the carrier 200A abuts the backrest 92. Referring to Figures 32 and 33, in some embodiments, the base 1 has a retractable structure, allowing the angle of the base 1 to be adjusted in the front-to-back direction. This allows the base 1 to be extended before placing the carrier 200A on the base 1 to facilitate placement of the carrier 200A. After placing the carrier 200A on the base 1, the base 1 can be shortened to clamp the carrier 200A between the backrest 92 and the stopper 2. The carrier 200A may be, for example, but not limited to, a pet carrier (e.g., a pet carrier or pet box). In this embodiment, the carrier 200A is specifically described using a pet box as an example. The carrier 200A includes a storage space (not numbered in the figure) for accommodating a pet. It will be appreciated that when the carrier 200A is clamped between the backrest 92 and the stopper 2, even if the vehicle brakes suddenly, the carrier 200A will not move excessively in the forward and backward directions, thereby reducing the possibility of injury to the pet.

[0002] "Referring to Figures 32 and 33, this embodiment shows an exemplary implementation of the base 1 and the stopper 2. Specifically, the base 1 includes two rods 10 spaced apart on the left and right. In some embodiments, the two rods 10 are parallel to each other. A LATCH structure 13A is provided at one end of each rod 10. The stopper 2 is generally U-shaped, including a rod 22A and two rods 21A spaced apart on the left and right. The ends of the two rods 21A are pivotally connected to the other ends of the two rods 10 through pivot portions 12A, and the other ends of the two rods 21A are connected through rods 22A. In some embodiments, the rods 10, 21A, and 22A can be made of hollow tubing. In some embodiments, when the carrier fixing device 100A is in the folded state, the stopper 2 is located between the two rods 10, and the rod 21A and the rod 10 are generally parallel. Continuing to refer to Figures 32 and 33, in some embodiments, The rod 10 may include at least two interlocking tubes that can be moved relative to each other to adjust the length of the base 1. The relative positions of the multiple tubes of the rod 10 can be locked by a position locking mechanism 110 to lock the length of the rod 10. More specifically, when the position locking mechanism 110 is locked, the multiple tubes of the rod 10 cannot or cannot easily extend relative to each other, and the length of the rod 10 is relatively fixed. When the position locking mechanism 110 is released, the multiple tubes of the rod 10 can easily extend and retract relative to each other, allowing the length of the rod 10 to be adjusted. Specifically, in this embodiment, the rod 10 includes a first tube 101A and a second tube 102A. One end of the first tube 101A is connected to a LATCH structure 13A, and the other end of the first tube 101A is interlocked with the exterior of the second tube 102A. The end of the second tube 102A, distal from the first tube 101A, is pivotally connected to the corresponding rod 21A via a pivot portion 12A. The position locking mechanism 110, for example, includes a plurality of holes 111 disposed in the first tube 101A and a locking pin (not shown) disposed in the first tube 102A. When the position locking mechanism 110 is in the locked state, the locking pin is inserted into one of the plurality of holes 111, preventing the first tube 101A and the second tube 102A from sliding relative to each other. When the position locking mechanism 110 is in the unlocked state, the locking pin is removed from the hole 111, allowing the first tube 101A and the second tube 102A to slide relative to each other to adjust the length of the rod 10.Of course, the base 1 can also have other embodiments. It only needs to have a LATCH structure 13A for connecting to the connection structure (ISOFIX structure 912) of the vehicle seat 900 and be connected to the stopper 2 to cooperate with the stopper 2 to define a space for accommodating the carrier 200A. For example, in some embodiments, the two rods 10 of the base 1 can be connected by at least one connecting member (not shown in the figure, such as a connecting rod or connecting plate) to provide a more stable structure for the base 1. In some embodiments, the connecting member can be connected between the first tubes 101A of the two rods 10. In some embodiments, the connecting member can be connected between the second tubes 102A of the two rods 10. In some embodiments, the stopper 2 can be fixedly connected to the base 1 and cannot pivot, which is also within the scope of protection of this invention. The stopper 2 can also have other embodiments, not limited to the U-shaped structure described above. For example, in some embodiments, the stopper 2 can be H-shaped or T-shaped. The stopper 2 only needs to be connected to the base 1 and can limit the forward movement of the carrier 200A. In some embodiments, the vehicle securing device 100A may also be configured with a top tether (not shown). One end of the top tether may be connected to the stop 2 (e.g., to the rod 22A), while the other end of the top tether extends rearward from above the backrest 92 and connects to an anchor structure within the vehicle. Sixth Embodiment: Figures 39 and 40 show perspective views of a vehicle securing device 100A in a deployed state, from different perspectives, according to a sixth embodiment of the present invention. Figure 41 shows a perspective view of a vehicle 200A mounted on a vehicle seat 900 using the vehicle securing device 100A, with the vehicle securing device 100A in the deployed state. Figure 42 shows a side view of the vehicle securing device 100A, vehicle 200A, and vehicle seat 900 shown in Figure 41. The vehicle securing device 100A provided in this embodiment is a variation of the vehicle securing device 100A provided in the fifth embodiment described above. Unless otherwise specified, the structure of the vehicle securing device 100A of this embodiment can refer to the structure of the vehicle securing device 100A of the fifth embodiment described above. Referring to Figures 39 and 40 , in some embodiments, the vehicle securing device 100A may also be configured with a shock-absorbing structure 4. This shock-absorbing structure 4 may be mounted on the base 1 and / or the stopper 2. The vehicle securing device 100A abuts the vehicle 200A via the shock-absorbing structure 4. During emergency braking, the shock-absorbing structure 4 can cushion the impact force on the vehicle 200A, preventing the vehicle 200A from directly striking the rod of the vehicle securing device 100A and potentially injuring the pet inside.As shown in Figure 42, the shock-absorbing structure 4 disposed on the stopper 2 has a side facing the vehicle 200A that protrudes outward relative to the stopper 2 (protrudes toward the vehicle 200A). When the vehicle is in emergency braking, the shock-absorbing structure 4 contacts the vehicle 200A before the stopper 2. This embodiment shows an exemplary implementation of the shock-absorbing structure 4. Specifically, the shock-absorbing structure 4 includes a mesh structure 41A and at least one shock-absorbing material 42A disposed within the mesh structure 41A. The mesh structure 41A may be a fabric mesh or a metal mesh. In some embodiments, the mesh structure 41A is connected to both the rod 22A and the two rods 21A. The shock-absorbing material 42A faces the vehicle 200A and is configured to contact the vehicle 200A. In some embodiments, a plurality of shock-absorbing materials 42A are provided, and the plurality of shock-absorbing materials 42A may be disposed on the mesh structure 41A in any suitable manner. In some embodiments, the shock-absorbing material 42A may have a single-layer structure or a multi-layer structure. The single-layer shock-absorbing material 42A may include, but is not limited to, a foam material layer. In some embodiments, the multi-layer structure of the shock-absorbing material 42A includes multiple layers of material. In some embodiments, the multi-layered material may be made of a composite multi-layer material with shock-absorbing properties. Referring to FIG. 42 , in some embodiments, the material layer 421 of the shock-absorbing material 42A, located near the vehicle 200A, may be made of a material with higher hardness but lower thickness, while the material layer 422 located farther from the vehicle 200A may be made of a material with lower hardness but higher thickness. This allows the vehicle 200A to directly impact the higher hardness material layer 421 during emergency braking. The impact force can be quickly diffused along the higher hardness material layer 421 rather than concentrated at the point of impact. The diffused impact force can be evenly applied to the lower hardness material layer 422, where it can be fully absorbed by the lower hardness and thickness of the material layer 422. It will be appreciated that while the shock-absorbing material 42A is described above using two material layers 421 and 422 as an example, in actual applications, the multi-layer structure of the shock-absorbing material 42A may include more than two material layers. While the shock-absorbing structure 4 provided on the stopper 2 is described above as an example, it will be appreciated that any suitable shock-absorbing structure may be provided on the base 1, and further description will not be given here. Seventh Embodiment: Figures 43 and 44 show perspective views of a vehicle securing device 100A according to a seventh embodiment of the present invention in a deployed state from different perspectives. Figure 45 shows a perspective view of a vehicle 200A mounted on a vehicle seat 900 using the vehicle securing device 100A, with the vehicle securing device 100A in the deployed state.FIG46 illustrates a side view of the vehicle securing device 100A, vehicle 200A, and vehicle seat 900 shown in FIG45 . The vehicle securing device 100A provided in this embodiment is a variation of the vehicle securing device 100A provided in the sixth embodiment described above. Unless otherwise specified, the structure of the vehicle securing device 100A in this embodiment may refer to the structure of the vehicle securing device in the sixth embodiment described above. This embodiment provides another embodiment of a shock-absorbing structure 4 provided on a stopper 2. Specifically, the shock-absorbing structure 4 may be connected to the two rods 21A of the stopper 2. In some embodiments, the shock-absorbing structure 4 has a relatively large area for contact with the vehicle 200A. In some embodiments, the length of the shock-absorbing structure 4 in the left-right direction may be greater than the distance between the two rods 21A. In some embodiments, the shock-absorbing structure 4 may comprise, for example, a single layer of shock-absorbing material (such as, but not limited to, foam). In some embodiments, the shock-absorbing structure 4 may comprise multiple layers of shock-absorbing material. The description of the multiple layers in the sixth embodiment is provided above and will not be repeated here. Eighth Embodiment: Figures 47 and 48 show perspective views of a vehicle securing device 100A according to an eighth embodiment of the present invention in a deployed state from different perspectives. Figure 49 shows a perspective view of a vehicle 200A mounted on a vehicle seat 900 using the vehicle securing device 100A, with the vehicle securing device 100A in the deployed state. Figure 50 shows a side view of the vehicle securing device 100A, vehicle 200A, and vehicle seat 900 shown in Figure 49. The vehicle securing device 100A provided in this eighth embodiment is a variation of the vehicle securing device 100A provided in the sixth embodiment. Unless otherwise specified, the structure of the vehicle securing device 100A in this eighth embodiment can be referenced to the structure of the vehicle securing device 100A in the sixth embodiment. This eighth embodiment provides another embodiment of a shock-absorbing structure 4 disposed on a stopper 2. The shock-absorbing structure 4 is disposed on at least one of the rod 22A and the two rods 21A. The shock-absorbing structure 4 protrudes outward from the stopper 2 on one side of the vehicle 200A. In some embodiments, the shock-absorbing structure 4 can be adhered to the corresponding rod by gluing. In some embodiments, the shock-absorbing structure 4 can be integrated with the corresponding rod by overmolding. In some embodiments, the shock-absorbing structure 4 includes at least one shock-absorbing sleeve 43, which can be sleeved onto at least one of the rod 22A and the two rods 21A. In some embodiments, the shock-absorbing sleeve 43 can comprise a single layer of shock-absorbing material (e.g., but not limited to, foam).In some embodiments, the shock-absorbing structure 4 may include multiple layers of material with shock-absorbing properties. The description of the multiple layers can be found in the sixth embodiment above and will not be repeated here. In some embodiments, each shock-absorbing sleeve 43 circumferentially covers the corresponding rod. In some embodiments, each shock-absorbing sleeve 43 may conformally wrap around the corresponding rod. In some embodiments, the outer cross-section of each shock-absorbing sleeve 43 is circular. In some embodiments, the shock-absorbing structure 4 may not completely circumferentially cover the corresponding rod; the shock-absorbing structure 4 may be disposed only in the area of ​​the corresponding rod facing the vehicle 200A. Ninth Embodiment FIG51 shows a perspective view of a vehicle securing device 100A according to a ninth embodiment of the present invention. The vehicle securing device 100A is mounted on a vehicle seat 900 and in an unfolded state, with the vehicle 200A separated from the vehicle securing device 100A. FIG52 shows a perspective view of the vehicle securing device 100A mounted on a vehicle seat, with the vehicle 200A mounted on the vehicle securing device 100A. FIG53 shows a perspective view of the U1-U1 cross-section of FIG52. Figure 54 shows a front view of the first positioning structure 3 shown in the partially enlarged view Q in Figure 53 . Figures 55 to 60 show various variations of the first positioning structure 3 shown in Figure 54 . The carrier securing device 100A provided in this embodiment is a variation of the carrier securing device 100A provided in the fifth embodiment described above. Unless otherwise specified, the structure of the carrier securing device 100A in this embodiment may refer to the structure of the carrier securing device in the fifth embodiment described above. Referring to Figures 51 to 53 , in this embodiment, a first positioning structure 3 is provided between the base 1 of the carrier securing device 100A and the bottom surface 203 of the carrier 200A. This first positioning structure 3 is used to determine the relative position of the carrier 200A and the base 1. In some embodiments, the first positioning structure 3 may be a snap-fit ​​structure. More specifically, the first positioning structure 3 includes at least one snap-fit ​​member provided on at least one of the base 1 and the carrier 200A, detachably snapping the base 1 and the carrier 200A together via the at least one snap-fit ​​member. In some embodiments, the first positioning structure 3 can lock the left-right position of the carrier 200A and the base 1, preventing the carrier 200A from sliding left-right relative to the base 1. FIG. 51 , FIG. 53 , and FIG. 54 illustrate exemplary implementations of the first positioning structure 3. The second positioning structure 3 includes a first clamping member 31A and a second clamping member 32A. The first clamping member 31A is disposed on the bottom surface 203 of the carrier 200A, and the second clamping member 32A is disposed on the base 1.The first K-type connector 31A protrudes downward from the bottom surface 203 of the carrier 200A. The first long connector 31A has a receiving portion 310 and a K-type connector 311 communicating with the receiving portion 310. The second K-type connector 32A protrudes upward from the base 1. The second K-type connector 32A can enter the receiving portion 310 via the locking interface 311, allowing the second locking element 32A to removably engage with the first locking element 31A. More specifically, when the carrier 200A is placed on the carrier fixture 100A, the second locking element 32A contacts the locking interface 311, pushing the locking interface 311 open. After the second locking element 32A enters the receiving portion 310, the locking interface 311 automatically resets, connecting the first and second locking elements 31A and 32A together and preventing them from disengaging. In some embodiments, the portion of the second locking element 32A that enters the receiving portion 310 matches the shape of the receiving portion 310. In some unillustrated embodiments, the first positioning structure 3 may further include a locking member and a first unlocking member, with the first unlocking member being operably connected to the locking member. When the carrier 200A and the base 1 are snap-fitted together, the locking member locks the carrier 200A and the base 1, preventing them from separating. When the locking member locks the carrier 200A and the base 1, the locking structure of the first positioning structure 3 becomes inseparable. Specifically, in this embodiment, the first and second locking members 31A and 32A are inseparable. In some embodiments, the locking member may also lock the front-to-back position of the carrier 200A and the base 1, preventing the carrier 200A from sliding forward or backward relative to the base 1. When the connection between the first and second clamping members 31A and 32A needs to be released, the first release member drives the locking member to the release position, releasing the locking member from the carrier 200A and the base 1. The carrier 200A is then lifted upward to separate the first and second K-type connectors 31A and 32A. As mentioned above, in some embodiments, the base 1 includes two rods 10, and the second K-type connector 32A can be disposed on at least one of the rods 10. As described in the above embodiments, the rods 10 can include multiple interconnected tubes that are capable of relative movement to allow the rods 10 to extend or retract in length. The second clamping member 32A can be mounted on the outermost tube of the multiple tubes. Specifically, in this embodiment, the retractable rod 10 includes a first tube 101A and a second tube 102A. The first tube 101A is interconnected with the second tube 102A, and the second clamping member 32A can be disposed on the first tube 101A. In some embodiments, each rod 10 may be provided with one, two or more second clamping members 32A.The bottom surface 203 of the carrier 200A may be provided with one, two, or more first clamping members 31A at positions corresponding to each rod 10. In some embodiments, when two or more second clamping members 32A are provided on the rod 10, these clamping members 32A are spaced apart along the angular direction of the rod 10. FIG55 illustrates a variant embodiment of the first positioning structure 3. More specifically, the second clamping member 32A comprises a hollow receiving portion 320 and a clamping interface 321A communicating with the receiving portion 320. The second clamping member 31A can enter the receiving portion 320 through the clamping interface 321A, allowing the first clamping member 31A and the second clamping member 32A to be removably engaged. In some embodiments, the interior 322A of the second clamping member 32A may be hollow. FIG56 illustrates another variant embodiment of the first positioning structure 3, which may comprise a magnetic structure. More specifically, the first positioning structure 3 includes at least one magnetic member disposed on at least one of the base 1 and the carrier 200A, with the base 1 and the carrier 200A being detachably connected via the at least one magnetic member. In some embodiments, the first positioning structure 3 includes a first magnetic member 33 and a second magnetic member 34. The first magnetic member 33 is disposed on the bottom surface 203 of the carrier 200A, and the second magnetic member 34 is disposed on the rod 10 of the base 1. As previously described, the rod 10 may include a first tube 101A and a second tube 102A that are sleeved together, and the second clamping member 32A may be disposed on the outer portion of the first tube 101A. When the carrier 200A is placed on the base 1, the oppositely polarized north and south poles of the first magnetic member 33 and the second magnetic member 34 attract each other, thereby locating the carrier 200A. To separate the base 1 and the carrier 200A, the first magnetic member 33 and the second magnetic member 34 can be moved away from each other. In some embodiments, the carrier 200A can be first moved to a position where the like magnetic poles of the first magnetic member 33 and the second magnetic member 34 repel each other. The repulsive magnetic force can then be used to easily remove the carrier 200A. Figure 57 illustrates another variant embodiment of the first positioning structure 3. This embodiment modifies the carrier 200A based on the first positioning structure 3 shown in Figure 54. More specifically, the bottom surface 203 of the carrier 200A is provided with a recess 2030, and the first clamping member 31A is located within the recess 2030. In some embodiments, the first clamping member 31A is located within the recess 2030 and does not protrude relative to the bottom surface 203. This makes the first clamping member 31A less susceptible to impact from external objects.In some embodiments, when the first clamping member 31A and the second clamping member 32A are engaged, the first positioning structure 3 can be located within the recess 2030. In some embodiments, the recess 2030 can be deep enough to fully accommodate the rod 10, thereby supporting the bottom surface 203 of the carrier 200A with the seat cushion 91. In some embodiments, the recess 2030 and the rod 10 cooperate to help define the left-right position of the carrier 200A relative to the base 1. Of course, in some embodiments, the bottom of the first clamping member 31A can protrude downward from the recess 2030 (i.e., the first clamping member 31A has a portion located below the bottom surface 203), or the bottom of the first clamping member 31A can be flush with the bottom surface 203. FIG58 illustrates another variant embodiment of the first positioning structure 3. This embodiment modifies the first clamping member 31A and the second clamping member 32A based on the first positioning structure 3 shown in FIG57. In some embodiments, the outer contour of the first clamping member 31A can match the shape of the recess 2030. The bottom of the first clamping member 31A slightly protrudes downward from the recess 2030. The interior 312 of the first clamping member 31A can be hollow. The second fixing member 32A can wrap around the rod 10 (more specifically, the first tubular member 101A of the rod 10). In some embodiments, the second K-connector 32A can be cylindrical. Figure 59 shows another variant embodiment of the first positioning structure 3. This embodiment mainly modifies the first positioning structure 3 shown in Figure 57 with the second clamping member 32A. The second clamping member 32A can be integrally formed with the rod 10 (more specifically, the first tubular member 101A of the rod 10). Figure 60 shows another variant embodiment of the first positioning structure 3. The main difference between this embodiment and the first positioning structure 3 shown in FIG58 is that the first positioning structure 3 omits the second clamping member 32A. The first clamping member 31A directly engages with the rod 10 (more specifically, the first tube 101A of the rod 10). FIG61 shows a variation of the first positioning structure 3 shown in FIG51. In some embodiments, at least one first clamping member 31A can have a relatively large angle, and / or at least one second clamping member 32A can have a relatively large angle. In this way, when the carrier 200A is mounted on the carrier fixture 100A, the first clamping member 31A and the second clamping member 32A can slide relative to each other in the front-to-back direction to adjust the carrier 200A to an appropriate position.Furthermore, the longer second clamping member 31A and / or the third clamping member 32A can improve the versatility of the carrier securing device 100A and the carrier 200A, and can also reduce the precision requirements for the placement of the first clamping member 31A and the second clamping member 32A. Unless there is a conflict, the carrier securing device 100A provided in this embodiment can utilize the shock-absorbing structure 4 provided in the aforementioned embodiments. Tenth Embodiment: Figures 62 to 64 illustrate a variant embodiment of the carrier 200A provided in accordance with the tenth embodiment of the present invention. The carrier 200A can be provided with a second positioning structure 5, which is used to determine the relative position of the carrier 200A and the stopper 2 of the carrier securing device 100A.

One end of the fixing strap 53 is connected to the carrier 200A, and the other end can be connected to the rod 21A or the rod 22A. In some embodiments, the other end of the fixing strap 53 can be connected to the rod 22A via an annular sleeve 530. Unless otherwise specified, the second positioning structure 5 of this embodiment can be combined with the carrier 200A of any embodiment of the present invention. FIG. 65 shows a perspective view of a carrier fixing device 100A according to a tenth embodiment of the present invention. FIG. 66 shows a perspective view of the carrier fixing device 100A installed on a vehicle seat 900.Figure 67 shows a side view of a carrier 200A mounted on a vehicle seat 900 using the carrier securing device 100A, with the carrier securing device 100A in its deployed state. This embodiment is a variation of the carrier securing device 100A provided in the fifth embodiment. Unlike the fifth embodiment, a first tube 101A provided with a LATCH structure 13A is nested within a second tube 102A. The position locking mechanism 110 can employ any suitable structure. An exemplary structure of the position locking mechanism 110 is shown in the thirteenth embodiment below. Unless otherwise specified, the carrier securing device 100A provided in this embodiment can utilize the shock-absorbing structure 4 provided in the aforementioned embodiments. Unless otherwise specified, the carrier securing device 100A provided in this embodiment can be combined with the carrier 200A provided in any of the aforementioned embodiments. Twelfth Embodiment Figure 68 shows a perspective view of a carrier securing device 100A and a carrier 200A provided in accordance with the twelfth embodiment of the present invention, with the carrier 200A separated from the carrier securing device 100A. This embodiment is a variation of the carrier securing structure 100 provided in the eleventh embodiment. Unless otherwise specified, the structure of the carrier securing device 100A can refer to the description of the eleventh embodiment. As shown in FIG68 , a first positioning structure 3 as described in the ninth embodiment can be provided between the base 1 of the carrier securing device 100A and the carrier 200A. It is understood that the first positioning structure 3 may include a first clamping member 31A and a second clamping member 32A. The first clamping member 31A is provided on the bottom surface 203 of the carrier 200A. Unlike the ninth embodiment, the second clamping member 32A is provided on the second external tubular member 102A of the rod 10. Alternatively, the first positioning structure 3 may include a first magnetic member provided on the bottom surface 203 of the carrier 200A and a second magnetic member provided on the second external tubular member 102A. Unless otherwise specified, the specific implementation of the first positioning structure 3 can refer to the description of the ninth embodiment and will not be repeated here. Twelfth Embodiment: Figure 69 shows a partial cross-sectional view of a carrier securing device 100A and a carrier 200A according to the twelfth embodiment of the present invention. Unless otherwise specified, the structure of the carrier securing device 100A can be referred to the description of the tenth embodiment above. Figures 70 to 72 show cross-sectional views taken along the line U2-U2 in Figure 69 , illustrating different operating states of the position locking mechanism 110. A first positioning structure 3 is provided between the carrier securing device 100A and the carrier 200A.In some embodiments, the first positioning structure 3 includes a first K-type connector 31A, which is mounted in the recess 2030 of the bottom surface 203 of the carrier 200A. The first K-type connector 31A has a receiving portion 310 and a K-type interface 311 communicating with the receiving portion 310. The first K-type connector 31A can be directly engaged with the rod 10 (more specifically, the second tubular member 102A of the rod 10). That is, the second tubular member 102A can enter the receiving portion 310 through the interface 311 to engage with the first engaging member 31A. This embodiment shows an exemplary embodiment of the position locking mechanism 110. The position locking mechanism 110 includes a third magnetic member 113, a fourth magnetic member 114, an elastic arm 115, and a locking hole 112. Referring to Figures 69 to 71, in some embodiments, the interior 312 of the first engaging member 31A is hollow. The first end 1151 of the elastic arm 115 is fixed to the interior 312 of the first clamping member 31A. The first magnetic member 113 is located at the second end 1152 of the elastic arm 115. A through-hole 313 is provided in the first clamping member 31A between the second tube 102A and the first magnetic member 113. The through-hole 313 is opposite the locking hole 112. The locking hole 112 is provided in the second tube 102A (see FIG. 65 ). The second magnetic member 114 is provided on the first tube 101A, for example, on the outer circumference of the second tube 101A. In some embodiments, the fourth magnetic member 114 includes a third magnetic strip 1141. Referring to FIG. 71 , when the second tube 101A and the third tube 102A move relative to each other, and when the third magnetic strip 1141 and the third magnetic member 113 face each other, the magnetic poles of the adjacent sides of the first magnetic strip 1141 and the third magnetic member 113 are opposite and attract each other. Thus, the third magnetic member 113 can pass through the through-hole 313 and the locking hole 112 to attract the first magnetic strip 1141. This facilitates locking the relative positions of the first tube 101A and the second tube 102A, and simultaneously locks the relative positions of the carrier 200A and the second tube 102A, thereby strengthening the connection between the carrier 200A and the carrier fixture 100A. Referring to FIG. 72 , in some embodiments, the fourth magnetic member 114 further includes a second magnetic strip 1142. In some embodiments, the second magnetic strip 1142 and the first magnetic strip 1141 can be spaced apart.Referring to FIG. 71 , when the first tube 101A and the second tube 102A move relative to each other, and when the second magnetic strip 1142 and the third magnetic member 113 face each other, the magnetic poles of the adjacent sides of the second magnetic strip 1142 and the third magnetic member 113 are identical and repel each other, allowing the second magnetic strip 1142 to easily move toward the interior 312 of the first clamping member 31A. It should be noted that the position locking mechanism 110 provided in this embodiment is also applicable to embodiments in which the second tube 102A is sleeved within the first tube 101A. Accordingly, the locking hole 112 is provided on the exterior of the first tube 101A, and the fourth magnetic member 114 is provided on the interior of the second tube 102A, for example, on the outer circumference of the second tube 102A. Fourteenth Embodiment: Figure 73 shows a perspective view of a vehicle securing device 100A according to the fourteenth embodiment of the present invention. The vehicle securing device 100A is mounted on a vehicle seat 900 and in an unfolded state, with the vehicle 200A separated from the vehicle securing device 100A. Figure 74 shows a partial cross-sectional view taken along line U3-U3 in Figure 73 . For ease of illustration, the rod 10 is shown in dashed lines in Figure 74 . Figure 75 shows a perspective view of the first positioning structure in the first embodiment. The vehicle securing device 100A in this embodiment is a variation of the vehicle securing device 100A in the thirteenth embodiment. Unless otherwise specified, the structure of the vehicle securing device 100A in this embodiment can be referenced to the structure of the vehicle securing device 100A in the thirteenth embodiment. Referring to Figures 73 and 74 , the bottom portion 203 of the vehicle 200A is provided with at least one recess 2030 for accommodating at least one rod 10 of the base 1. In this embodiment, the rod 10 is extendable in length. It will be appreciated that in other embodiments, the rod 10 may have a fixed length and be non-extendable. In some embodiments, the recess 2030 extends through the front side 201A and the rear side 202A of the carrier 200A. In this embodiment, the first positioning structure 3 includes at least one first clamping member 31A. The wall of the recess 2030 is provided with at least one hole 2031. The first clamping member 31A is retractably positioned in a corresponding hole 2031, allowing the first clamping member 31A to have a locked position and a released position. Referring to FIG. 74 , when the first K-connector 31A is in the locked position, the first R-connector 31A extends into the recess 2030 and locks the rod 10 therein, preventing the rod 10 from being removed from the recess 2030.When the carrier 200A needs to be removed from the carrier securing device 100A, the first clamping member 31A is driven to move along direction P toward the unlocked position, shortening the length of the first clamping member 31A within the recess 2030. When the first clamping member 31A moves to the unlocked position, it no longer interferes with the movement of the rod 10 out of the recess 2030. Referring to FIG. 75 , in some embodiments, the first positioning structure 3 may further include at least one reset member 36, which applies a force to the first clamping member 31A toward the locked position. In the absence of an external force, the reset member 36 maintains the first clamping member 31A in the locked position. In some embodiments, the reset member 36 comprises, for example, a spring. In some unillustrated embodiments, the first positioning structure 3 further includes at least one second release member, operably connected to the first clamping member 31A, for driving the first clamping member 31A toward the unlocked position. In some embodiments, the first release member is, for example, rigidly connected to the second clamping member 31A. In some embodiments, the second release member is connected to the first locking member 31A via a traction member (e.g., a wire rope). In some embodiments, the first locking member may be, but is not limited to, a button. Referring to Figures 74 and 75 , in some embodiments, the first locking member 31A may have, for example, a guide ramp 315 . When the carrier 200A is mounted on the base 1 , the rod 10 can apply a force toward the unlocked position via the guide ramp 315 to the first locking member 31A. This allows the rod 10 to pass over the first locking member 31A and be locked in the recess 2030 by the first locking member 31A without operating the second release member. Referring to Figures 73 and 75 , in some embodiments, the first positioning structure 3 includes four first locking members 31A: a first locking member 31Aa, a first locking member 31Ab, a first locking member 31Ac, and a first locking member 31Ad. Four first clamping members 31A are arranged in a rectangular array at the bottom of the carrier 200A. In some embodiments, these first clamping members 31A move in the same direction toward a locked position or a released position. In some embodiments, first clamping members located in the same row in the left-right direction (e.g., first clamping member 31Aa and first clamping member 31Ab) move in opposite directions toward a locked position or a released position; first clamping members located in the same column in the front-to-back direction (e.g., first clamping member 31Aa and first clamping member 31Ac) move in the same direction toward a locked position or a released position. Referring to FIG. 75 , in some embodiments, at least two first clamping members 31A may be connected via a linkage device 6.When any one of the multiple first clamping members 31A connected by the linkage device 6 moves to the unlocked position, the other first clamping members 31A simultaneously move to the unlocked position. Continuing with FIG. 75 , in some embodiments, the linkage device 6 may include a linkage assembly 62 connected between two first clamping members 31A in the same row (e.g., the first clamping member 31Aa and the first clamping member 31Ab), and a linkage member 61 connected between two first clamping members 31A located diagonally opposite each other (e.g., the first clamping member 31Aa and the first clamping member 31Ad). In some embodiments, the linkage assembly 62 includes a four-bar linkage mechanism. Specifically, the four-bar linkage mechanism includes a first link 621, a second link 622, a third link 623, and a fourth link 624. The first, second, third, and fourth links 621, 622, 623, and 624 are connected in pairs to form connection points, corresponding to pivot axes A1, A2, A3, and A4. One of the four connection points is a fixed pivot point. In this embodiment, pivot axis A1 is fixed to the bottom of the carrier 200A as a fixed pivot point. The second link 623 and the fourth link 624, connected at a central connection point opposite to fixed pivot axis A1 (corresponding to pivot axis A2), are connected to the first and second clips 31Aa and 31Ab, respectively, via pivot axes A5 and A6. The linkage assembly 62 allows the first and second clips 31Aa and 31Ab to move synchronously to a locked or released position. For example, when either the first clamping member 31Aa or the first clamping member 31Ab moves toward the unlocked position under the drive of the first release member, the pivot axis A2 moves away from the pivot axis A1, driving the other of the first clamping member 31Aa and the first K clamping member 31Ab to move synchronously toward the locked position. When either the first long member 31Aa or the first K clamping member 31Ab moves toward the locked position under the drive of the reset member 36, the pivot axis A2 moves toward the pivot axis A1, driving the other of the first K clamping member 31Aa and the first clamping member 31Ab to move synchronously toward the locked position. In some embodiments, the linkage member 61 includes, but is not limited to, a traction member (e.g., a wire rope). In some embodiments, the diagonally located first clamping member 31Aa and the first clamping member 31Ad are connected by one linkage member 61, while the diagonally located first clamping member 31Ab and the first clamping member 31Ac are connected by another linkage member 61.When the first clamping member 31Aa and the first clamping member 31Ab move synchronously toward the unlocked position, the first clamping member 31Ac and the first clamping member 31Ad also move synchronously toward the unlocked position under the action of the two linkage members 61. Fifteenth Embodiment: FIG76 shows a perspective view of a vehicle securing device 100A according to the fifteenth embodiment of the present invention. The vehicle securing device 100A is mounted on a vehicle seat 900 and is in an unfolded state, with the vehicle 200A separated from the vehicle securing device 100A. FIG77 shows a partial cross-sectional view taken along line U4-U4 of FIG76. For ease of illustration, the rod 10 is shown in dashed lines in FIG77. The vehicle securing device 100A provided in this embodiment is a variation of the vehicle securing device 100A provided in the fourteenth embodiment described above. Unless otherwise specified, the structure of the vehicle securing device 100A in this embodiment can refer to the structure of the vehicle securing device 100A in the fourteenth embodiment described above. In this embodiment, the first positioning structure 3 includes a pair of first clamping members 31A. Two opposing holes 2031 are provided on two opposing walls of the recess 2030 of the carrier 200A. The two paired first clamping members 31A are retractably disposed in the opposing holes 2031. The two paired first clamping members 31A have a locked position and a released position. Referring to FIG. 77 , when the two first clamping members 31A are in the locked position, they extend a certain distance into the recess 2030, locking the rod 10 therein and preventing it from being removed. When the two first clamping members 31A move in a split-apart manner along directions P1 and P2 to the released position, the two first clamping members 31A no longer interfere with the rod 10's removal from the recess 2030. In some embodiments not shown, the first positioning structure 3 may further include at least one reset member. The reset member applies a force to the first clamping members 31A to move them toward the locked position. In the absence of an external force, the reset member maintains each first clamping member 31A in the locked position. In some embodiments, the reset member comprises, for example, a spring. In some unillustrated embodiments, the first positioning structure 3 may further include a second release member, the first release member operatively connected to the first clamping member 31A, and the second release member configured to drive the first clamping member 31A toward the unlocked position. In some embodiments, each first clamping member 31A may also be connected via a linkage device to enable synchronous movement toward the unlocked position.Sixteenth Embodiment: FIG78 shows a perspective view of a vehicle securing mechanism 1000 according to the sixteenth embodiment of the present invention mounted on a seat 900, with the roof assembly 11A of the vehicle 100 in a closed position. FIG79 shows an exemplary perspective view of the base 200B in FIG78. FIG80 shows a perspective view of the vehicle 100 in FIG78. FIG81 shows a bottom view of the vehicle 100 shown in FIG80. FIG82 shows another perspective view of the vehicle securing mechanism 100 shown in FIG78 and the seat 900, with the roof assembly 11A of the vehicle 100 in an open position. Referring to FIG78 to FIG81, the vehicle securing mechanism 1000 includes the vehicle 100 and a base 200B. The vehicle 100 is detachably mounted on the base 200B, which is detachably mounted on the seat 900. The vehicle 100 is secured to the seat 900 via the base 200B. The seat 900 may be, for example, but is not limited to, a vehicle seat. Referring to FIG. 78 , seat 900 includes a seat cushion 91, a backrest 92, and a headrest 93. In some embodiments, the headrest 93 has an insertion rod (not shown) that inserts into the backrest 92 from the top surface. The front of the seat 900 is typically provided with a connection point, located at the intersection of the front surfaces of the backrest 92 and the front surface of the seat cushion 91. This connection point is used to connect with an ISOFIX structure or LATCH structure 270 (see FIG. 79 ). In some embodiments, the back or top surface of the backrest 92 is provided with an anchor structure (not shown). The anchor structure may be a rod-shaped member that connects to the anchor of the top tether assembly. Referring to FIG. 78 and FIG. 79 , the base 200B includes a base portion 21B and a top portion 22B. The base portion 21B is intended to be placed on the seat cushion 91. The top portion 22B extends upward from the rear end of the base portion 21B and is intended to abut against the backrest 92. In some embodiments, the base 200B (more specifically, the base portion 21B) can be configured with a TSOFIX or LATCH structure. The TSOFIX or LATCH connectors can be removably connected to connection points on the seat 900. While the ISOFIX or LATCH structure is not shown in the figure, reference can be made to the ISOFIX or LATCH structure of a child safety seat. In some embodiments, the base 200B can be secured to the seat 900 using a safety belt compatible with the seat 900. The top support portion 22B can be configured with a top tether assembly. Referring to Figures 80 and 82, the carrier 100 is used to accommodate a pet and can be a pet carrier or a pet carrier.In this embodiment, the carrier 100 is specifically described using a pet carrier as an example. The carrier 100 includes a roof assembly 11A and a container body 12B. When the carrier 100 is removed from the base 200B, it can be used independently as a pet transport vehicle. The container body 12B, for example, is a box-shaped structure that defines a container space 1201 for accommodating an infant or pet. This container space 1201 has a top opening 120 through which the pet can enter. In some embodiments, the container body 12B is approximately rectangular in shape, with side surfaces of the container body 12B including two opposing first side surfaces 121 and two opposing second side surfaces 122, with the two second side surfaces 122 located between the two first side surfaces 121. In this embodiment, the first side surfaces 121 extend in the front-to-back direction, and the second side surfaces 122 extend in the left-to-right direction. In some embodiments, the length of the first side 121 extending in the front-to-back direction is greater than the length of the second side 122 extending in the left-to-right direction. In some embodiments, a fixing ring 1202 may be provided inside the container body 12B. This fixing ring 1202 can be connected to a clip on a pet vest or pet collar. Specifically, two fixing rings 1202 may be provided, arranged diagonally. When the top opening 120 is open, the connection between the fixing rings 1202 and the pet vest prevents the pet from accidentally escaping. In some embodiments, the container body 12B may include a foam housing, a bracket device mounted on the exterior of the housing, and a seat fabric. The bracket device is used to enhance the structural strength of the housing and may be a metal frame. The seat fabric, for example, wraps around the exterior of the housing and bracket device to give the container body 12B a clean appearance. Of course, the structure and shape of the container body 12B can also be implemented in other embodiments and are not limited to the above examples. The housing body 12B may also be provided with a handle 123, which is U-shaped. The two ends of the U-shaped handle 123 are pivotally connected to the sides of the housing body 12B. In this embodiment, the two ends of the handle 123 are more preferably pivotally connected to the top center of the two first side surfaces 121. Figures 79 to 81 illustrate an exemplary structure in which the carrier 100 is detachably mounted on the base 200B. Of course, the detachable connection between the carrier 100 and the base 200B is not limited to the following examples. The base 21B may be provided with a locking mechanism 23A, and the bottom of the carrier 100 may be provided with a locking rod 13B. The locking mechanism 23A and the locking rod 13B are detachably engaged to secure the carrier 100 to the base 21B.In some embodiments, the locking mechanism 23A includes a plurality of locking slots 230 provided on the base 21B and a plurality of locking hooks 231 that engage with the locking slots 230. These locking slots 230 are spaced apart in the front-to-back direction and / or the left-to-right direction. The locking rods 13B of the carrier 100 can be inserted into these locking slots 230 and locked by the locking hooks 231. In this embodiment, the bottom of the carrier 100 is provided with two locking rods 13B spaced apart in the front-to-back direction. Each locking rod 13B protrudes downward from the bottom of the accommodating body 12B and extends in the left-to-right direction. The locking mechanism 23A includes four locking slots 230. Each locking rod 13B corresponds to two locking slots 230. Of course, the embodiments of the locking rods 13B and the locking mechanism 23A are not limited to the above examples. For example, in some unillustrated embodiments, the bottom of the vehicle 100 may be provided with only one locking rod 13B extending in the left-right direction. This locking rod 13B is offset relative to the center plane MM of the vehicle 100 at the bottom of the vehicle 100. In some embodiments, the locking mechanism 23A may further include a release member (not shown) operably connected to each locking hook 231 to drive the locking hook 231 to release the locking rod 13B. In some embodiments, the base 21B may further be provided with a display device that indicates whether the locking rod 13B is locked by the locking hook 231. The ceiling assembly 11A is mounted to the top of the accommodating body 12B. In some embodiments, the ceiling assembly 11A is, for example, detachably connected to the accommodating body 12B. In some alternative embodiments, the ceiling assembly 11A is non-detachably connected to the accommodating body 12B. The ceiling assembly 11A includes a tarpaulin 111A and a bracket (not shown) that supports the tarpaulin 111A. In this embodiment, the ceiling assembly 11A is a fully enclosed ceiling, having a fully extended state and a fully collapsed state. In some embodiments, the ceiling assembly 11A may also have an intermediate collapsed state between the fully extended and collapsed states. When the ceiling assembly 11A is in the fully extended state shown in FIG. 78 , the ceiling assembly 11A completely covers the top opening 120 of the accommodating body 12B (see FIG. 82 ). When the ceiling assembly 11A is in the fully collapsed state shown in FIG. 82 , the top opening 120 is fully opened.In some embodiments, as shown in FIG82 , the ceiling assembly 11A may include two split halves 112A. The two halves 112A can rotate in opposite directions away from each other, thereby opening the top opening 120 from the center. In some alternative embodiments, the center of the ceiling assembly 11A is not openable. When the top opening 120 is to be opened, the front and / or rear sides of the ceiling assembly 11A are flipped upward, separating the front and / or rear sides of the ceiling assembly 11A from the receiving wood body 12B, thereby opening the top opening 120. Of course, the embodiment of the ceiling assembly 11A is not limited to the above example. It should be noted that while the ceiling assembly 11A in this embodiment is described as a fully enclosed ceiling, in some alternative embodiments, the ceiling assembly HA may be a partially enclosed ceiling. It will be appreciated that even in a fully extended state, a partially enclosed ceiling only covers a portion of the top opening 120 and does not completely close the top opening 120. It should be noted that although the carrier 100 in this embodiment is described as being equipped with a ceiling assembly 11A, in some alternative embodiments, the carrier 100 may not be equipped with the ceiling assembly 11A. A carrier 100 without the ceiling assembly 11A is also within the scope of protection of this application. Seventeenth Embodiment Figures 83 and 84 show elevation views of a carrier 100 provided according to the seventeenth embodiment of the present invention from different perspectives. This carrier 100 is a variation of the carrier 100 of the sixteenth embodiment described above. Unless there is any conflict, the structure of the carrier 100 in this embodiment may refer to the structure of the carrier 100 in the sixteenth embodiment described above. As shown in Figures 83 and 84, the carrier 100 includes a ceiling assembly 11A and a container body 12B. The ceiling assembly 11A is described as a fully enclosed ceiling. The bottom of the container body 12B is provided with a snap-fit ​​and: 13B. The carrier 100 can be detachably connected to the base 200B described in the sixteenth embodiment via a snap-fit ​​rod 13B. The carrier 100 is also equipped with a collision avoidance device 14A, which is detachably connected to at least one of the accommodating body 12B, the roof assembly 11A, and the handle 123. The collision avoidance device 14A is used to cover at least a portion of the roof assembly 11A, for example, the front or rear side of the roof assembly HA. The collision avoidance device 14A protects the roof assembly 11A from damage in the unfolded state due to impact, thereby preventing the damaged roof assembly 11A from protruding into the accommodating space 1201 (see FIG. 82 ) and potentially injuring the pet.On the other hand, when a pet in the accommodating space 1201 collides with the ceiling assembly 11A, the anti-collision protection device 14A can also cushion the impact. In some embodiments, the anti-collision protection device 14A covers areas of the ceiling assembly 11A where the structural strength is weak, the impact resistance is poor, and where pets are likely to collide. An exemplary embodiment of the anti-collision protection device 14A is shown in the following embodiment. The anti-collision protection device 14A may include a cover 141 and two second connectors 142. The cover 141 may, for example, have a shape that is narrow at both ends and wide in the middle. When the anti-collision protection device 14A is in the use position shown in Figures 83 and 84, the cover 141 covers the unfolded ceiling assembly 11A, forming an arched shape that conforms to the shape of the unfolded ceiling assembly 11A. The ends of the cover 141 correspond to the left and right sides of the vehicle 100. The two second connectors 142 are provided at both ends of the cover 141. A first connector 124 is provided on each side of the left fabric of the carrier 100. Each second connector 142 can be detachably connected to a corresponding first connector 124, allowing the cover 141 to laterally cover the viewing area located at the front or rear of the ceiling assembly 11A. Referring to Figures 83 and 84, each second connector 142 can be secured to each end of the cover 141 via a webbing 143, for example, and the second connector 142 can be a hook. The container body 12B is provided with at least one first connector 124. More specifically, one, two, or more first connectors 124 are provided on each of the two first side surfaces 121 of the container body 12B. The first connector 124 is, for example, a metal ring that can be secured to the seat fabric of the container body 12B via a webbing 1241. The first connector 124 is located near the pivot point O between the handle 123 and the container body 12B. When multiple first connectors 124 are provided, they are, for example, arranged symmetrically about the pivot point O, and the second connector 142 can be connected to any of the first connectors 124 as needed. Of course, the embodiments of the first connector 124 and the second connector 142 are not limited to the above examples. In some alternative embodiments, the first connector 124 can be provided on the ceiling assembly 11A±, such as the tent fabric of the ceiling assembly 11A. In this case, the first connector 124 and the second connector 142 can be, for example, mating structures such as hook-and-loop fasteners or snaps. Alternatively, in some alternative embodiments, the first connector 124 can be provided on the handle 123.When the first connector 124 is provided on the handle 123, the first connector 124 may be a hole formed in the handle 123, with the second connector 142 detachably connected to the hole. Referring to FIG83 , when the anti-collision protection device 14A is in use, at least one connection point 145 may be formed between the lower edge of the anti-collision protection device 14A and the outer side of the housing body 12B. These connection points 145 help secure the relative position of the anti-collision protection device 14A and the roof assembly 11A, preventing the anti-collision protection device 14A from sliding. When there are more than 1 connection points 145, for example, the connection points correspond to different outer side surfaces of the housing body 12B. The connection points 145 may be formed by cooperating fasteners, Velcro, snaps, or other structures. In some alternative embodiments, at least one connection point may be formed between the anti-collision protection device 14A and the outer side surface of the roof assembly 11A. Of course, in some alternative embodiments, the anti-collision protection device 14A may form at least one connection point with both the housing wood body 12B and the ceiling assembly 11A. Continuing with FIG83 , in some embodiments, the material layers of the cover 141 may include, for example, an inner fabric layer and an outer fabric layer made of fabric, with the inner fabric layer facing the ceiling assembly 11A and the outer fabric layer facing away from the ceiling assembly 11A. An energy absorber 146 (shown in dashed lines in FIG83 ) may be sandwiched between the inner and outer fabric layers to cushion impacts. In some embodiments, the energy absorber 146 may be positioned on the surface of the inner fabric layer facing away from the outer fabric layer. The energy absorber 146 may be positioned in the transverse middle region of the cover 141 to locally enhance the impact resistance (i.e., anti-collision protection) of the ceiling assembly 11A in the area most susceptible to impact. The energy absorber 146 may be a single-layer or multi-layer structure. When the energy absorbing device 146 has a single-layer structure, it can be made of, for example, inert memory foam or other suitable materials. When the energy absorbing device 146 has a multi-layer structure, it can be, for example, a combination of EPP (expanded polypropylene) material layers, EPS (expanded polystyrene) material layers, and EPE (expanded polyethylene, also known as pearl cotton) material layers, or a combination of inert memory foam material layers and PE (polyethylene) material layers, or a combination of other suitable material layers. Of course, in some alternative embodiments, the energy absorbing device 146 is not limited to being located in the transverse middle region of the cover 141; the energy absorbing device 146 can be located in any region of the cover 141 that covers the ceiling assembly 11A.In some embodiments, the thickness of the energy absorbing device 146 may not be uniform. The portion of the energy absorbing device 146 corresponding to the lateral middle region of the hood 141 may be thicker, while the portions of the energy absorbing device 146 corresponding to the end regions of the hood 141 may be thinner. In some embodiments, two anti-collision protection devices 14A may be provided to respectively cover the front and rear sides of the roof assembly 11A, thereby improving the impact resistance of each covered area of ​​the roof assembly HA. Eighteenth Embodiment: Figures 85 and 86 show perspective views of a vehicle securing mechanism 1000 according to the eighteenth embodiment of the present invention from different perspectives. The vehicle securing mechanism 1000 includes a vehicle 100 and a base 200Bo. The base 200B may refer to the description of the sixteenth embodiment. The vehicle 100 is a variation of the vehicle 100 of the seventeenth embodiment described above. Unless otherwise specified, the structure of the vehicle 100 in this embodiment may refer to the structure of the vehicle 100 in the seventeenth embodiment described above. As shown in Figures 85 and 86 , the vehicle 100 includes a roof assembly 11A, a container body 12B, and an anti-collision protection device 14A. The roof assembly 11A is illustrated using a partially enclosed roof as an example. The roof assembly 11A is connected to a portion of the upper edges of two first side surfaces 121 and the upper edge of one second side surface 122. A locking rod 13B is provided at the bottom of the container body 12B. The locking rod 13B allows the vehicle 100 to be detachably connected to the base 200B. The container body 12B is provided with at least one U-shaped bar (also known as a U-shaped elastic bar) 1203, which serves as an anti-collision protection device. Each U-shaped bar 1203 includes two opposing arms 12031 and a horizontal bar 12032 connecting the two arms 12031. The U-shaped bar 1203 is inverted on the receiving wooden bench 12B, with the horizontal bar 12032 located at the top ends of the two arms 12031. In some embodiments, the two arms 12031 extend upward from the upper edge of each first side surface 121 that is not covered by the ceiling assembly 11A. When there is more than one U-shaped bar 1203, multiple U-shaped bars 1203 may be spaced apart along the front-to-back direction, with the multiple U-shaped bars 1203 being parallel to each other.

[0003] The U-shaped strip 1203 can be made of a soft material, including, but not limited to, plastic or metal. The U-shaped strip 1203 can elastically deform when subjected to external forces, thereby providing impact cushioning. The anti-collision protection device 14A is used to cover at least a portion of the roof assembly 11A to protect the deployed roof assembly 11A. For details regarding the structure of the anti-collision protection device 14A and the method of securing the anti-collision protection device 14A to at least one of the housing body 12B, the roof assembly 11A, and the handle 123, refer to the description of the seventeenth embodiment. In some embodiments, a thickened energy absorber 146 is provided on the inner fabric layer in the transverse middle region of the cover 141. The energy absorber 146 contacts the roof assembly 11A to provide locally enhanced cushioning performance. Figures 87 and 88 illustrate a modified embodiment of the carrier securing mechanism 1000 shown in Figures 85 and 86 , primarily modifying the U-shaped bars 1203 shown in Figures 85 and 86 . As shown in Figures 87 and 88 , the multiple U-shaped bars 1203 are not arranged parallel to one another, but are instead arranged circumferentially at predetermined angles. The U-shaped bars 1203 are positioned above the area of ​​the accommodating body 12B not covered by the roof assembly 11A. In some embodiments, the arms 12031 of the multiple U-shaped bars 1203 may be connected along the same centerline. Nineteenth Embodiment: Figures 89 and 90 illustrate perspective views of a carrier 100 according to a nineteenth embodiment of the present invention from different perspectives. This carrier 100 is a modification of the carrier 100 provided in the eighteenth embodiment. Unless otherwise specified, the structure of the carrier 100 in this embodiment may refer to the structure of the carrier 100 in the eighteenth embodiment. As shown in Figures 89 and 90 , unlike the eighteenth embodiment described above, this embodiment omits the U-shaped bar 1203. Instead, an anti-collision protection device 15A is installed in the area of ​​the container body 12B not connected to the ceiling assembly 11A. More specifically, the anti-collision protection device 15A faces the ceiling assembly 11A and is removably connected to the upper edge of the container body 12B. More specifically, the bottom 151 of the anti-collision protection device 15A is C-shaped, covering portions of the upper edges of the two first side surfaces 121 and the upper edge of the one second side surface 122. In some embodiments, the bottom 151 of the anti-collision protection device 15A is provided with a slot, for example, that can be removably engaged with the upper edge of the container body 12B. Of course, the anti-collision protection device 15A can also be installed on the upper edge of the container body 12B in other suitable ways.The anti-collision protection device 15A not only cushions impacts from outside the carrier 100 or from pets, but also effectively prevents pets within the accommodating space 1201 from falling through the top opening 120 to the exterior of the carrier 100, thereby ensuring the safety of the pets within the accommodating space 1201. Referring to FIG. 89 , the anti-collision protection device 15A includes a first portion 1501 extending upward from the first side 122 and a second portion 1502 extending upward from the first side 121. The height of the first portion 1501 is greater than that of the second portion 1502. In some embodiments, the transition between the first portion 1501 and the second portion 1502 forms a step. In alternative embodiments, the upper edge of the second portion 1502 extends obliquely to the upper edge of the first portion 1501. In some embodiments, the heights of the first portion 1501 and the second portion 1502 may be substantially the same. In some embodiments, the anti-collision protection device 15A may be made of, for example, an integrally molded foam material. In some embodiments, the anti-collision protection device 15A may include a fabric layer and an energy-absorbing device wrapped within the fabric layer. The energy-absorbing device may, for example, be made of an integrally molded foam material. In some embodiments, the inner side of the anti-collision protection device 15A facing the accommodating space 1201 may be provided with an energy-absorbing device 1503. The energy-absorbing device 1503 may be attached to the inner side of the anti-collision protection device 15A by bonding or other means. The energy-absorbing device 1503 may be made of a material with a cushioning effect and may have an appropriate volume and thickness. The material and structure of the energy-absorbing device 1503 may, for example, refer to the material and structure of the energy-absorbing device 146 in the second embodiment. FIG. 91 to FIG. 93 of the tenth embodiment show perspective views of a vehicle 100 according to the tenth embodiment of the present invention from different perspectives. This vehicle 100 is a variation of the vehicle 100 of the sixteenth embodiment described above. Unless otherwise specified, the structure of the vehicle 100 in this embodiment may refer to the structure of the vehicle 100 in the sixteenth embodiment described above. As shown in Figures 91 to 93, the carrier 100 includes a ceiling assembly 11A and a housing body 12B. The figures illustrate the ceiling assembly 11A as a fully enclosed ceiling. In other embodiments, the ceiling assembly 11A may also be a partially enclosed ceiling. A locking rod 13B is provided at the bottom of the housing body 12B. The carrier 100 can be detachably connected to the base 200B via the locking rod 13B. The carrier 100 is also equipped with a protective sheet 16, which can be a light-transmitting protective net or an opaque protective cloth.The protective sheet 16 includes two opposing first and second sides 161 and 162. The first side 161 is connected to the housing body 12B, while the second side 162 extends upward and is detachably connected to the handle 123. When the carrier 100 is mounted on the seat 900 via the base 200B, the handle 123 is rotated to tension the protective sheet 16. Once tensioned, the handle 123 locks, maintaining the tensioned state. The tensioned protective sheet 16 covers at least a portion of the ceiling assembly 11A, providing impact protection. In some embodiments, the housing body 12B may be provided with a receiving cavity 1206 for accommodating the protective sheet 16. The protective sheet 16 can have a storage state, in which it is contained within the cavity 1206, and a use state, in which it extends from the cavity 1206 and is connected to the handle 123. The opening 12061 of the accommodating chamber 1206, through which the protective sheet 16 extends, can be located on the bottom surface of the accommodating body 12B, on a side surface of the accommodating body, or on the upper edge of the accommodating body 12B. In some embodiments, an automatic retractor (not shown) is provided within the accommodating chamber 1206. The automatic retractor may include a retracting shaft and a coil spring connected to the retracting shaft. The first side 161 of the protective sheet 16 extends into the accommodating chamber 1206 through the opening 12061 and connects to the automatic retractor. When the second side 162 of the protective sheet 16 is connected to the handle 123, the length of the protective sheet 16 extending from the accommodating chamber 1206 can be varied by changing the pivotal position of the handle 123 relative to the accommodating body 12B. The protective sheet 16 extending from the accommodating chamber 1206 is maintained taut by the automatic retractor. When the protective sheet 16 is no longer needed, the automatic retractor automatically retracts the protective sheet 16 into the accommodating chamber 1206. Of course, in some embodiments without an automatic retractor, the protective sheet 16 can be manually retracted into the accommodating cavity 1206. Referring to FIG. 92 , a connecting strap 1621 is provided on the first side 162 of the protective sheet 16. The connecting strap 1621 is provided with a positioning portion 1622.

As shown in Figures 102 and 103, the vehicle 100 includes a ceiling assembly 11A and a housing 12B. The ceiling assembly 11A in the figures is illustrated as a fully enclosed ceiling; in other embodiments, the ceiling assembly 11A may also be a partially enclosed ceiling.In some alternative embodiments, the roof assembly 11A can be equipped with the anti-collision protection device 14A described in the second embodiment. In some alternative embodiments, the vehicle 100 may not be equipped with the roof assembly HA. A stopper 18 is provided at the front end of the base 200B. Stopper 18 extends upward from the front end of the base 21B to a certain height to protect the accommodating body 12B and the roof assembly 11A. Stopper 18 comprises a U-shaped rod, which includes a rod 182 and two rods 181 spaced apart on the left. The lower ends of the two rods 181 are connected to the front end of the base 200B (more specifically, the front end of the base 21B), and the upper ends of the two rods 181 are respectively connected to the rod 182. In some embodiments, rods 181 and 182 can be made of hollow tubing. Stopper 18 can also include an energy absorption device 180. During emergency braking, the energy absorbing device 180 can cushion the impact force exerted on the vehicle 100. This embodiment illustrates an exemplary implementation of the energy absorbing device 180. Specifically, the energy absorbing device 180 comprises a mesh structure, which can be a fabric mesh or a metal mesh. The mesh structure is connected to both the rod 182 and the two rods 181. In some embodiments, the energy absorbing device 180 may further include at least one shock-absorbing material disposed on the mesh structure. The shock-absorbing material is disposed at least on the side of the mesh structure facing the vehicle 100. When an impact occurs, the shock-absorbing material abuts the vehicle 100. In some embodiments, the rod 181 may be a telescopic rod, comprising at least two tubes nested together. The relative position of the at least two tubes can be locked by a position locking mechanism (not shown). When the position locking mechanism is locked, the multiple tubes of the rod 181 cannot or cannot be easily extended relative to each other. When the position locking mechanism is released, the multiple tubes of the rod 181 can easily be extended relative to each other, allowing the length of the rod 181 to be adjusted. When the rod 181 is a telescopic rod, the innermost tube of the telescopic rod is connected to the base 21B, and the mesh structure of the energy absorbing device 180 is connected to the outermost tube of the telescopic rod. The height of the mesh structure can be adjusted by adjusting the length of each rod 181. In some embodiments, the vehicle securing mechanism 1000 may also be configured with a top tether assembly 4A. The top tether assembly 4A includes an anchor 41B and a webbing 42B. One end of the webbing 42B can be removably connected to the stopper 18 (for example, to the rod 182). The other end of the webbing 42B is provided with an anchor 41B. The anchor 41B can be moved downward over the top of the backrest 92 to removably connect to the anchor structure on the back of the backrest 92.In some alternative embodiments, one end of the top tether assembly 4A is connected to the stopper 18, and the other end can be connected to the headrest 93. In some embodiments, a length adjuster is provided on the webbing 42B to allow for adjustment of the length of the webbing 42B. Figures 104 and 105 illustrate a modified embodiment of the carrier securing mechanism 1000 shown in Figures 102 and 103, primarily modifying the structure of the stopper 18. As shown, the stopper 18 can have a dry-bend, multi-segment design, with adjustable pivot angles between the different segments to provide more comprehensive protection for the carrier 100. More specifically, referring to Figures 104 and 105, the stopper 18 includes a first segment 18a and a second segment 18b. The first segment 18a comprises two rods 18a1 spaced apart from each other. One end of each rod 18a1 is connected to the front end of the base 21B, while the other ends of each rod 18a1 extend upward. The second section 18b includes a U-shaped frame 18b1, which includes a member 18b2 and two members 18b3. One end of each member 18b3 is pivotally connected to the upper ends of two rods 18a1, while the other ends of each rod 18b3 are connected to rod 18b2. Both the third and fourth sections 18a and 18b are equipped with energy-absorbing devices 180. In some embodiments, the rods 18a1 may be telescopic rods. A rotation locking mechanism (not shown) may be provided between the first and second sections 18a and 18b. This mechanism can lock the relative pivotal position of the first and second sections 18a and 18b, thereby maintaining the stopper 18 in a specific position. In some embodiments, the rotation locking mechanism can have a locked state and a released state. When the rotation locking mechanism is in the locked state, the first and second sections 18a and 18b cannot rotate relative to each other. When the rotation locking mechanism is in the unlocked state, the first section 18a and the second section 18b can rotate relative to each other. It should be noted that while the stopper 18 comprises two sections in the above embodiment, in other embodiments, the stopper 18 may comprise three or more sections. In some embodiments, the stopper 18 includes a section that is connected to and supported by the support portion 22B of the base 200B. Figures 106 to 108 illustrate an exemplary embodiment in which the stopper 18 shown in Figures 102 and 103 is housed in the base 200B. The base 200B is internally provided with a receiving cavity 201. The lower end of the stopper 18 is pivotally connected to a sliding member 186 via a pivot joint 185. The sliding member 186 slidably engages with the receiving cavity 201.The pivot joint 185 is equipped with a rotation locking mechanism (not shown) that locks the relative pivotal position of the stopper 18 and the slider 186. To accommodate the stopper 18, the rotation locking mechanism is released, the stopper 18 is rotated in direction T1 to a horizontal position, and then pushed into the receiving cavity 201 in direction T2. ​​To use the stopper 18, the stopper 18 is pulled in a direction opposite to direction T2. ​​After the stopper 18 is removed from the receiving cavity 201, the stopper 18 is rotated in a direction opposite to direction T1. Once the stopper 18 is fully rotated, the rotation locking mechanism is locked, preventing the stopper 18 from rotating relative to the slider 186. In some embodiments, the lower end of the stopper 18 is directly or indirectly detachably connected to the slider 186. For example, when the stopper 18 is no longer needed, the stopper 18 can be detached from the pivot joint 185, or the stopper 18 and the pivot joint 185 at its lower end can be detached from the sliding member 186. When the stopper 18 has a foldable structure, such as that shown in Figures 104 and 105, and needs to be stored, the multiple sections of the stopper 18 can be folded together, with the folded sections essentially parallel to each other, and then the folded stopper 18 can be pushed into the receiving cavity 201. In some alternative embodiments, the sliding member 186 and receiving cavity 201 shown in Figures 106 to 108 can be omitted, and the stopper 18 can be pivotally connected to the base 21B of the base 200B via the pivot joint 185, and the stopper 18 and the base 21B of the base 200B are directly or indirectly detachably connected. When the stopper 18 is no longer needed, it can be disengaged from the pivot joint 185, or it can be disengaged from the base 21B together with the pivot joint 185 at its lower end. In some unillustrated embodiments, a receiving groove for accommodating the stopper 18 can be provided on the upper surface of the base 21B. The stopper 18 is pivotally connected to the front end of the base 21B via the pivot joint. When the stopper 18 is no longer needed, it can be rotated in a direction opposite to the direction T1 shown in FIG106 to directly engage the receiving groove. When the stopper 18 is configured with a mesh structure of the energy-absorbing device 180, the mesh structure has a certain degree of elastic deformation, which will not affect the connection between the carrier 100 and the base 200B. 109 and 110 illustrate another variant embodiment of the carrier securing mechanism 1000 shown in FIG. 102 and FIG. 103 , wherein the stopper 18 is detachably connected to the base 21B, and more specifically, the lower end of the stopper 18 is detachably connected to the base 21B.More specifically, the front end of the base 21B is provided with a socket 210. The lower end of the rod 181 can be inserted into the socket 210, securing the stopper 18 to the base 200B.
