[Modes for carrying out the invention]

[0034] The technical concepts and content of this disclosure will be explained below with reference to the drawings and exemplary embodiments. In the drawings and descriptions, identical or similar parts are given the same or corresponding element reference numerals, and furthermore, the drawings are drawn for ease of understanding, and the dimensions and shapes of each element in the drawings do not represent the actual dimensions or proportional relationships of the elements.

[0035] Furthermore, the following description relating to the drawings and embodiments does not mean to limit the scope of the disclosure to a single implementation, and other implementations are possible by replacing some or all of the elements described or illustrated. In addition, where certain elements of the disclosed embodiments can use some or all of known elements, in some cases only the portion of such known elements necessary for understanding the embodiments of the disclosure will be described, and detailed descriptions of other portions of such known elements will be omitted to avoid obscuring the concepts and embodiments of the disclosure.

[0036] As shown in Figures 1A and 1B, these are schematic external views of an animal transport cart 1 according to one embodiment of the present disclosure. The animal transport cart 1 of this embodiment includes a cart body 11 and an animal carrier 12, where the animal carrier 12 is stably coupled to the cart body 11 in a detachable manner. The cart body 11 may have a configuration similar to that of a conventional shopping cart, and may include, for example, a cart handle 111, a mounting layer 112, a frame vertical rod 113 connecting the cart handle 111 and the mounting layer 112, and a wheel member 114 installed at the bottom of the cart body 11. In this embodiment, the cart body 11 further includes a support portion 115, which is installed parallel to the mounting layer 112 and connected to the frame vertical rod 113 at a position higher than the mounting layer 112. The support portion 115 is used to support the animal carrier 12 and to stably connect it.

[0037] Specifically, in this embodiment, the support layer 112 is provided at the lower part of the cart body 11 that is close to the ground and is connected to the lower end of the frame vertical rod 113. The support section 115 includes a support frame, which may be a frame structure composed of, for example, four side parts or side bars, or a hollow frame, and is manufactured from a rigid material (e.g., stainless steel, metal, hard plastic, etc.) and is strong enough to adequately support the weight of the animal carrier 12 and the animal being carried. The support section 115 is provided at the upper part of the cart body 11 that is away from the ground and is connected to the upper end of the frame vertical rod 113 at a position close to the cart handle 111. In other words, the animal carrier 12 of this embodiment, when connected to the support part 115, forms an upper and lower layer structure with the loading layer 112 of the cart body 11. When a user (for example, a pet owner or pet caregiver) needs to shop or transport goods, they place their pet on the upper animal carrier 12 of the animal transport cart 1 and place the purchased or transported goods on the lower loading layer 112.

[0038] As shown in Figure 1C, it is a schematic external view of the animal transport cart 1 according to this embodiment from another perspective. In this embodiment, the animal carrier 12 includes a housing 121 and a bracket device 122. The housing 121 consists of a bottom and a peripheral wall connected to the bottom, which is used to form a carrying space in which to carry an animal. The bracket device 122 includes a first bracket 1221 and a second bracket 1222 which are provided around the outside of the peripheral wall of the housing 121 and whose contours correspond to the outside of the peripheral wall of the housing 121, which provide support force to the housing 121 and improve the strength with which the housing 121 (animal carrier 12) can carry an animal. The bracket device 122 further includes a third bracket 1223 which is connected to the outside of the bottom of the housing 121 and is used to attach the animal carrier 12 to, for example, a vehicle fixing base or a cart fixing base (not shown). The first bracket 1221, the second bracket 1222, and the third bracket 1223 are connected to each other to form the bracket device 122 of the animal carrier 12. As described above, the bracket device 122 is coupled to the housing 121 on the outside of the peripheral wall and bottom of the housing 121.

[0039] As shown in Figure 1C and its enlarged section, in this embodiment, the animal carrier 12 includes a connecting structure 123 which is used in cooperation with the support portion 115 of the cart body 11, thereby stably connecting the animal carrier 12 and the cart body 11. In this embodiment, the connecting structure 123 is, for example, a pair of fixing lugs, but for concealment purposes, only one of the fixing lugs is shown in the figure. As shown in Figure 1C, the connecting structure 123 is located on opposing sides of the outer periphery wall of the housing 121 of the animal carrier 12 and is used to hang on the corresponding opposing sides of the support portion 115 of the cart body 11, and is stably connected to the opposing sides of the support portion 115 when the user applies a downward thrust to the housing 121. In this embodiment, the connecting structure 123 may be a member independent of the housing 121, and it may be installed on two opposing short sides of the first bracket 1221, thereby the housing 121 may be hooked over the two corresponding short sides of the support portion 115 of the cart body 11, and thus connected to the cart body 11. Alternatively, the connecting structure 123 may be formed integrally with the housing 121 and extend from the outer circumference of two opposing side walls of the housing 121, thereby the housing 121 may be hooked over the corresponding sides of the support portion 115 of the cart body 11, and thus stably connected to the cart body 11. In another embodiment, the connecting structure 123 may be located on the opposing long sides of the animal carrier 12, and it may be hooked over the two corresponding long sides of the support portion 115 of the cart body 11, and this disclosure does not restrict the installation position of the connecting structure 123 as long as the animal carrier 12 can be stably connected to the cart body 11.Furthermore, the connection structure 123 shown in Figures 1A to 1C is exemplified by a pair of fixing lugs, and this disclosure does not limit the number of connection structures 123 that can be installed. In other embodiments, the connection structure 123 of the animal carrier 12 may include at least one fixing lug, for example, in the embodiment shown in Figures 5A and 5B, the animal carrier 52 has only one fixing lug and is used to cooperate with the support portion 515 of the cart body 51 (details will be further explained below). Alternatively, the connection structure 123 may include at least two or more fixing lugs, for example, each fixing lug may be installed on at least two sides, at least three sides, or four sides of the animal carrier 12, and the animal carrier 12 may be stably connected to the cart body 11. This disclosure is not limited to embodiments of the connection structure 123.

[0040] According to this embodiment, the connecting structure 123 may be made of an elastic rigid material, such as metal, plastic, or wood. The connecting structure 123 is installed on the bracket device 122 (for example, the first bracket 1221) and is a component independent of the housing 121, or it is formed integrally with the bracket device 122 (for example, the first bracket 1221), or it is formed directly integrally with the housing 121.

[0041] According to this embodiment, the arrangement of the connection structure 123 allows the user to easily and stably connect the animal carrier 12 to the cart body 11 of the animal transport cart 1, and also allows the user to easily remove the animal carrier 12 and separate it from the cart body 11 according to the actual application scenario.

[0042] As shown in Figures 2A and 2B, they show schematic external views of an animal carrier 22 of an animal transport cart according to one embodiment of the present disclosure from different viewpoints, the animal carrier 22 having a structure and configuration similar to the animal carrier 12 described above, and including a housing 221 and a bracket device 222, the bracket device 222 mainly consisting of a first bracket 2221, a second bracket 2222, and a third bracket 2223 connected to each other, and coupled to the housing 221. The animal carrier 22 can also be stably connected to the cart body of an animal transport cart (e.g., the cart body 11 described above) by being hung via the connecting structure 223.

[0043] The difference between the animal carrier 22 of this embodiment and the animal carrier 12 described above is that the animal carrier 22 further includes an adjustment bracket 224, at least one pair of connecting structures 223 of the animal carrier 22 are provided on the opposing sides of the adjustment bracket 224, the adjustment bracket 224 has an expandable and contractible structure to form a pair of movable sides 224A, thereby adjusting the distance between the two connecting structures 223 (hereinafter also referred to as the "connection interval") according to the size of the support part and / or support frame of the cart body. In this embodiment, the long side of the adjustment bracket 224 is a movable side 224A with an expandable and contractible structure, and the short side of the adjustment bracket 224 is a fixed side to which the connecting structure 223 is provided.

One end of pin members 22418 and 22428 is inserted into and fixed in the fixing holes 22414 of the U-shaped inner tube 2241 and 22424 of the U-shaped inner tube 2242, respectively, while the other end is movably in contact with the inner wall of the connecting outer tube 2244. One end of pin members 22415, 22417, 22425, and 22427 is inserted into and fixed in the fixing holes 22431, 22441, 22432, and 22442 of the connecting outer tube, respectively, thereby connecting and fixing the inner tube and the outer tube. The other end is in contact with the guide grooves 22411, 22413, 22421, and 22423, respectively, forming the movable side 224A of the adjustment bracket 224.

[0045] According to this embodiment, when attaching the animal carrier 22 to the cart body (for example, the cart body 11 described above), the adjustment bracket 224 of the animal carrier 22 is adjusted accordingly according to the size of the support portion and / or support frame (for example, the support portion 115 described above) of the cart body, so that the size of the adjustment bracket 224 matches the size of the support portion. This allows the connection structure 223 provided on the adjustment bracket 224 to be connected to the support portion at an appropriate position, thereby stably connecting it to the cart body. In this embodiment, the size of the adjustment bracket 224 is also called the "adjustment bracket width," and means the distance between the opposing sides on which the connection structure of the adjustment bracket is provided. In this embodiment, the size of the support portion or support frame is also called the "support portion width" or "support frame width," and means the distance between the opposing sides on the support portion or support frame to which the animal carrier is engaged. In other words, the expandable and contractible structure of the movable side 224A of the adjustment bracket 224 allows the width of the adjustment bracket to be increased or decreased according to the width of the support section or support frame, and the connecting structure 223 provided on the adjustment bracket 224 is connected to the support section or support frame of the cart body at an appropriate position.

[0046] Furthermore, when adjusting the width of the adjustment bracket, the user pulls the two U-shaped inner tubes 2241 and 2242 outward, and the pin members 22416, 22426 and pin members 22414, 22424 are fixed and connected between the two U-shaped inner tubes 2241 and 2242, respectively, and the pin members 22416, 22426 and pin members 22414, 22424 are connected to the elastic elements 22451 and 22452, respectively, thus connecting the U-shaped inner tubes 2241 and 2242. They can be moved relative to the connecting outer tubes 2243 and 2244 (at which time the pin members 22416, 22426 and pin members 22414, 22424 also move into the connecting outer tubes 2243 and 2244, where the pin members 22416 and 22426 move away from each other, and the pin members 22414 and 22424 also move away from each other), and can be reset by the elastic action of the elastic elements 22451 and 22452, respectively. As the U-shaped inner tubes 2241 and 2242 are pulled and move outward, the guide grooves 22411 and 22413 of the U-shaped inner tube 2241 and the guide grooves 22421 and 22423 of the U-shaped inner tube 2242 are displaced outward by the guides of the pin members 22415, 22417, 22425, and 22427 respectively (at this time, the pin members 22415, 22425 and the pin members 22417 and 22427 are fixed and connected to the connecting outer tubes 2243 and 2244 respectively, and therefore, relative to the connecting outer tubes 2243 and 2244) (The position is fixed, and pin members 22416 and 22418 approach pin members 22415 and 22417 respectively, and pin members 22426 and 22424 approach pin members 22425 and 22427 respectively), and elastic elements 22451 and 22452 are pulled as the U-shaped inner tubes 2241 and 2242 move outward, thereby increasing the width of the adjustment bracket to adapt to the support part of the corresponding size, thereby adjusting the distance between the pair of connecting structures 223 (i.e., the "connection interval"). In this embodiment, the connecting structure 223 may be, for example, a fixed lug, which is attached to both opposing sides of the support part at an appropriate connection interval according to the adjustment of the adjustment bracket 224. In this embodiment, the size of the adjustment bracket 224 can be kept constant by connecting the connecting structure 223 to the support part of the cart body.When the connection between the connecting structure 223 and the support is released, the U-shaped inner tubes 2241 and 2242 move relative to each other (inward) due to the restoring force of the elastic elements 22451 and 22452 and return to their original positions, and the width of the adjustment bracket 224 returns to its original size. According to this embodiment, regardless of whether the size of the housing 221 of the animal carrier 22 itself matches the connecting bracket of the cart body, the animal carrier 22 can be adjusted by adjusting the adjustment bracket 224 to match the distance between the two opposing sides of the support. This allows it to be connected to the support in an appropriate position and stably connected to the cart body, thereby improving the flexibility of matching and application between the animal carrier and the cart body.

[0047] As shown in Figures 3A and 3B, they show a schematic external view of an animal transport cart 3 according to one embodiment of the present disclosure. The animal transport cart 3 of this embodiment has a structure and configuration similar to the animal transport cart 1 described above, and includes a cart body 31 and an animal carrier 32, where the animal carrier 32 is stably connected to the cart body 31 in a detachable manner. Similarly, the cart body 31 includes a cart handle 311, a mounting plate 312, a frame vertical rod 313 connecting the cart handle 311 and the mounting plate 312, a wheel member 314 installed at the bottom of the cart body 31, and a support part 315 (e.g., a support frame). The animal carrier 32 includes a housing 321 and a bracket device 322, the specific structure of which is similar to the animal carrier described above.

[0048] The difference between the animal transport cart 3 of this embodiment and the animal transport cart 1 is that the animal carrier 32 of the animal transport cart 3 is stably connected to the cart body 31 by a locking mechanism. As shown in the figure, in this embodiment, the support portion 315 of the cart body 31 includes a support frame and further includes connecting structures 3151 installed on two opposing short sides of the support frame, and connecting structures 325 are provided on the outside of the peripheral walls of the two opposing short sides of the animal carrier 32, and the connecting structures 325 of the animal carrier 32 can be matched and locked with the connecting structures 3151 of the support portion 315, thereby forming a stable connection between the animal carrier 32 and the cart body 31. In this embodiment, the connecting structure 3151 may be a connecting buckle, and the connecting structure 325 is a connecting seat that can partially accommodate the connecting structure 3151.

[0049] As shown in Figures 3B and 3C, they show enlarged partial cross-sectional views of the animal transport cart 3 of this embodiment and are used to illustrate the detailed structure of the connecting structure 325 (e.g., connecting seat) and connecting structure 3151 (e.g., connecting buckle) of this embodiment. The connecting structure 325 is installed on the outside of the peripheral walls of two opposing short sides of the housing 321 of the animal carrier and includes a connecting seat body 3251, the connecting seat body 3251 having at least a portion of the contour 3251A that matches the inner contour 3151A of the connecting structure 3151. The connecting structure 325 further includes an engagement pin 3252, one end of which cooperates with the engagement groove 3151B of the connecting structure 3151, and an elastic element 3253 connected to the other end, the elastic element 3253 abuts against the connecting seat body 3251, where the elastic element 3253 is used to provide a driving force that constantly moves the engagement pin 3252 to the engagement groove 3151A. A recessed contact surface 3252A is formed on the engagement pin 3252. The connection structure 325 further includes an operating key 3254, the lower part of which contacts the contact surface 3252A of the engagement pin 3252, and the upper part of which protrudes outside the connection seat body 3251 and is used for user pressing operations. When the connection structure 325 of the animal carrier 32 is to be removed and separated from the connection structure 3151 on the support portion 315 of the cart body 31, the user can press the operating key 3254 downward, thereby bringing the contact surface 3252A of the engagement pin 3252 into contact and applying pressure, which moves the engagement pin 3252 toward the rear end (towards the housing 321) and exits from the engagement groove 3151B of the connection structure 3151, releasing the lock between the connection structure 325 and the connection structure 3151, and detaching the animal carrier 32 from the cart body 31.

[0050] As shown in Figures 4A and 4B, these are schematic external views of an animal transport cart 4 according to one embodiment of the present disclosure, where Figure 4A shows the appearance of the cart when the animal carrier 42 is attached to the cart body 41, and Figure 4B shows the appearance of the cart when the animal carrier 42 is not attached to the cart body 41. In this embodiment, the cart body 41 of the animal transport cart 4 has a structure and configuration similar to that of the previously described embodiment, and includes a cart handle 411, a mounting layer 412, a frame vertical rod 413 connecting the cart handle 411 and the mounting layer 412, and a wheel member 414 installed at the bottom of the cart body 41. The animal carrier 42 includes a housing 421 and a bracket device 422, and its specific structure is similar to that of the animal carrier described above. The difference between this embodiment and the previously described embodiment is that in this embodiment, the connection structure of the animal carrier 42 is a pair of connection grooves 425 formed on the outside of the peripheral walls of two opposing short sides of the housing 421, and the connection structure of the cart body 41 is a positioning end 41543A protruding from the inside of the support part 415, with the connection grooves 425 being used to receive and join the protruding positioning end 41543A, thereby engaging and connecting with each other to stably connect the animal carrier 42 to the cart body 41.

[0051] More specifically, as shown in Figures 4C and 4D, Figure 4C is a top cross-sectional view of the animal transport cart 4 of this embodiment, and Figure 4D is an exploded schematic view of the animal carrier 42 and support section 415, used to explain the detailed structure of the connecting groove 425 of the animal carrier 42 and the support section 415 of the cart body 41 of this embodiment. In this embodiment, the support section 415 is mainly composed of an upper cover plate 4152 and a lower cover plate 4153 joined together, forming a storage space between the upper cover plate 4512 and the lower cover plate 4153, and the support frame 4151 is fixed in that storage space. A pair of opposing openings 4152A (only the openings 4152A are shown in the drawing as they are hidden) are opened on the inside of the upper cover plate 4152, and their positions correspond to a pair of connecting grooves 425 on the outside of the side wall of the short side of the housing 421 of the animal carrier 42. A positioning mechanism assembly 4154 is installed in the housing space of the support portion 415. The positioning mechanism assembly 4154 includes an operating key 41541, a pair of drive steel wires 41542, a pair of positioning protrusions 41543, a pair of positioning sliders 41544, and a pair of guide members 41545. Both sides of the operating key 41541 are connected to the guide members 41545 and the drive steel wires 41542, respectively. One end of the drive steel wires 41542 is connected to the guide member 41545, and the other end is connected to the positioning sliders 41544. The positioning sliders 41544 abut against the positioning protrusions 41543. The positioning protrusions 41543 have a positioning end 41543A that protrudes outside the support portion 415 through the opening 4152A of the upper cover plate 4152, and the other end is connected to an elastic element 41546. The elastic element 41546 provides a driving force that keeps the positioning projection 41543 constantly protruding into the opening 4152A.

[0052] When the animal carrier 42 is attached to the support portion 415, the positioning projection 41543, due to the action of the elastic element 41546, has its positioning end 41543A pass through the opening 4152A and protrude outside the support portion 415, engaging with a pair of connecting grooves 425 on the outside of the side wall of the short side of the housing 421 of the animal carrier 42. The engagement of the positioning end 41543A with the connecting grooves 425 allows the housing 421 to be positioned and locked on the support portion 415, thereby stably connecting the animal carrier 42 to the cart body 41. To remove the animal carrier 42 from the cart body 41, the user pulls the operating key 41541 outward along the direction of arrow A shown in Figure 4C, that is, to activate the guide member 41545 and drive the drive steel wire 41542, and then to drive the positioning slider 41544 to displace the positioning projection 41543 out of the connection groove 425, thereby releasing the connection of the housing 421 to the support part 415 and allowing the animal carrier 42 to be removed from the cart body 41.

[0053] In this embodiment, the animal carrier 42 of the animal transport cart 4 uses a pair of connecting grooves 425 on the outside of the side wall of the short side of the housing 421 as its connecting structure, and the cart body 41 uses positioning projections 41543 installed on the corresponding inside of the support portion 415 as its connecting structure, and the animal carrier 42 is connected to the cart body 41 by the coupling of the positioning projections 41543 and the connecting grooves 425. However, the disclosure is not limited thereto. In other embodiments, positioning projections may be installed on the outside of the side wall of the short side of the housing of the animal carrier, which will then connect to the connecting grooves provided on the corresponding inside of the support portion of the cart body, thereby connecting the animal carrier to the cart body.

[0054] As shown in Figures 5A and 5B, they show schematic external views of an animal transport cart 5 according to one embodiment of the present disclosure from different perspectives. The animal transport cart 5 of this embodiment includes a cart body 51 and an animal carrier 52, where the animal carrier 52 is stably connected to the cart body 51 in a detachable manner. The cart body 51 may have a configuration similar to that of a conventional shopping cart, for example, having a cart handle 511, a mounting layer 512, a frame vertical rod 513 connecting the cart handle 511 and the mounting layer 512, a wheel member 514 installed at the bottom of the cart body 51, and the mounting layer 512 is located in the lower part of the cart body 51 that is close to the ground and is connected to the lower end of the frame vertical rod 513. In this embodiment, the cart body 51 further includes a support portion 515 (e.g., a connecting back plate) which is substantially perpendicular to the mounting layer 512 and connected to two frame vertical rods 513, and is located at the upper end of the frame vertical rods 113 and close to the position of the cart handle 511. That is, the support portion 515 is located between the two frame vertical rods 513 and is higher than the position of the mounting layer 512. In this embodiment, the support portion 515 has a flat plate structure, i.e., it is a support plate (or "connecting back plate") connected between the two frame vertical rods 513.

[0055] In this embodiment, the animal carrier 52 includes a housing 521 and a bracket device 522, where the configuration of the bracket device 522 is similar to that of the bracket device described above. In this embodiment, the animal carrier 52 further includes a connecting structure 523 (e.g., a fixing lug), which is provided on the outside of the peripheral wall of the housing 521, for example, on the outside center of the long side peripheral wall 5211 of the housing 521. In this embodiment, the animal carrier 52 is hung on the support portion (connecting back plate) 515 of the cart body 51 via the connecting structure (fixing lug) 523, and is stably connected to the support portion (connecting back plate) 515 by the user applying a downward thrust to the housing 521, thereby attaching and fixing it to the cart body 51 and forming a stable connection, as shown in Figure 5B.

[0056] In this embodiment, the connecting structure 523 may be made of an elastic rigid material, such as metal, plastic, or wood, and has a certain strength to stably support the housing 521 of the animal carrier 52 when the animal carrier 52 is attached to the cart body 51. The connecting structure 523 may also be installed on the bracket device 522 (for example, its first bracket or second bracket), and may be a member independent of the housing 521, or may be directly formed integrally with the housing 521 and extend from the long side peripheral wall 5211 of the housing 521.

[0057] As shown in Figure 6A, it is a schematic external view of an animal transport cart 6 according to one embodiment of the present disclosure. The animal transport cart 6 has a structure and configuration similar to the animal transport cart described above, and includes a cart body 61 and an animal carrier 62, the animal carrier 62 being stably connected to the cart body 61 in a detachable manner. In this embodiment, the cart body 61 has a structure and configuration similar to the cart body described above, and includes a cart handle 611, a mounting layer 612, a frame vertical rod 613 connecting the cart handle 611 and the mounting layer 612, a wheel member 614 installed at the bottom of the cart body 61, and a support part 615, etc. The difference between this embodiment and the previously described embodiment is that in this embodiment, in addition to including a support frame, the support part 615 further includes a fixing base 6151, which is used to mount and fix the animal carrier 62 on it.

[0058] As shown in Figures 6B and 6C, schematic views of the animal transport cart 6 from different perspectives are shown to illustrate the cart body 61 and animal carrier 62 of the animal transport cart 6 of this embodiment. In this embodiment, the animal carrier 62 has a structure and configuration similar to the animal carrier described above and includes a housing 621 and a bracket device 622, where the bracket device 622 includes a first bracket 6221 and a second bracket 6222 that are provided around the outer edge of the housing 621 and whose contours correspond to the outer edge of the housing 621, thereby improving the load-bearing strength of the animal carrier 62, and also includes a third bracket 6223 provided on the outside of the bottom of the housing 621 for attaching the animal carrier 62 to, for example, a vehicle fixing base or a cart fixing base (not shown). The first bracket 6221, the second bracket 6222 and the third bracket 6223 are connected to each other to form the bracket device 622, and the bracket device 622 is coupled to the housing 621 on the outside of the housing 621.

[0059] As shown in Figures 6B and 6C, in this embodiment, the third bracket 6223 is a sealed frame enclosed by a pair of opposing long rods 62231 and 62232 and a pair of opposing short rods, and serves as the connection structure for the animal carrier 62 in this embodiment. The support portion 615 of the cart body 61 further includes a fixed base 6151, and fixed guide grooves 61511 and 61512 are formed in the fixed base 6151 to serve as the connection structure for the support portion 615. The third bracket 6223 of the support frame device 622 is inserted and fitted into its long rods 62231 and 62232, and the animal carrier 62 is joined to the fixed base 6151 by its third bracket 623, thereby attaching and fixing it to the cart body 61. In this embodiment, the orientation and structure of the fixed base 6151 and its fixed guide grooves 61511, 61512 are matched to the long rods 62231, 62232 of the third bracket 6223, but the disclosure is not limited thereto. Alternatively, in other embodiments, the orientation and structure of the fixed guide grooves may be formed to match the short rods of the third bracket, and this will be determined according to the actual application needs.

[0060] As shown in Figure 7A, it shows a schematic external view of an animal transport cart 7 according to one embodiment of the present disclosure. The animal transport cart 7 has a structure and configuration similar to the animal transport cart 6 described above and includes a cart body 71 and an animal carrier 72. The animal carrier 72 includes a housing 721 and a bracket device 722, which is stably connected to the cart body 71 in a detachable manner. In this embodiment, the cart body 71 has a structure and configuration similar to the cart body 61 described above and includes a cart handle 711, a mounting layer 712, a frame vertical rod 713 connecting the cart handle 711 and the mounting layer 712, a wheel member 714 installed at the bottom of the cart body 71, and a support part 715, etc. The difference between this embodiment and the previously described embodiment is that in this embodiment, the fixing base 7151 is further provided with locking hooks (only the locking hook 71513 provided at end 71512A) at both ends 71511A, 71511B, 71512A, and 71512B of the fixing guide grooves 71511 and 71512, respectively, thereby increasing the fixing capacity of the third bracket 722 to the fixing base 7151 (which will be further explained below) when the third bracket 722 of the bracket device 722 is joined to the fixing base 7151.

[0061] As shown in Figures 7B and 7C, they show schematic external views of the animal transport cart 7 from different angles, respectively, illustrating the cart body 71 and animal carrier 72 of the animal transport cart 7 in this embodiment. In this embodiment, the animal carrier 72 has a structure and configuration similar to that of the animal carrier 62, and includes a housing 721 and a bracket device 722, where the bracket device 722 includes a first bracket 7221 and a second bracket 7222 that are circumferentially provided around the outer edge of the housing 721 and whose contours correspond to the outer edge of the housing 721, and also includes a third bracket 7223 for attaching the animal carrier 72 to, for example, a vehicle fixing base or a cart fixing base. The first bracket 7221, the second bracket 7222 and the third bracket 7223 are connected to each other to constitute the bracket device 722, and the bracket device 722 is coupled to the housing 721 outside of the housing 721.

[0062] Similar to the animal transport cart 6 in the previously described embodiment, in this embodiment, the animal carrier 72 is connected to the cart body 71 by the corresponding long rods 72231 and 72232 of the third bracket 7223, which are inserted into and fitted into the fixing guide grooves 71511 and 71512, respectively, which serve as the connection structure for the fixing base 7151, thereby connecting to the cart body 71. The difference is that in this embodiment, locking hooks are provided at both ends of the fixing guide grooves 71511 and 71512 (ends 71511A, 71511B, 71512A, and 71512B shown in Figure 7A), for example, the hooks 71513 and 71514 shown in Figure 7C. When the third bracket 7223 is inserted and fitted into the fixing guide grooves 71511 and 71512, which form the connection structure of the fixing base 7151, by its opposing long rods 72231 and 72232, the engagement of the locking hooks 71513 and 71514 in the fixing guide grooves 71511 and 71512 with the pair of long rods 72231 and 72232 of the third bracket 7223 allows the third bracket 7223 to be stably connected to the fixing base 7151, thereby stably attaching the animal carrier 72 to the cart body 71.

[0063] In this embodiment, four locking hooks are installed on the fixed base 7151 (each installed on the four guide groove ends 71511A, 71511B, 71512A, and 71512B of the fixed base 7151 shown in Figure 7A, and for the sake of brevity in the drawing, only the locking hook 71513 installed on end 71512A is shown), but the disclosure is not limited thereto. In other embodiments, the number and installation positions of the locking hooks can also be determined according to the actual application needs, for example, by installing the locking hooks in the center of the fixed guide groove.

[0064] In this embodiment, a steel cable type unlocking mechanism can be further provided on the fixed base 7151, and by using an operating key to link the steel cable and the unlocking part, the locking hook is unlocked, thereby causing the third bracket of the animal carrier to retract from the locking hook and the fixed guide groove.

[0065] As shown in Figures 8A and 8B, they show schematic external views of an animal transport cart 8 according to one embodiment of the present disclosure from different perspectives. The animal transport cart 8 has a structure and configuration similar to the animal transport cart described above and includes a cart body 81 and an animal carrier 82. The animal carrier 82 is stably connected to the cart body 81 in a detachable manner. In this embodiment, the cart body 81 has a structure and configuration similar to the cart body described above and includes a cart handle 811, a mounting layer 812, a frame vertical rod 813 connecting the cart handle 811 and the mounting layer 812, and a wheel member 814 installed at the bottom of the cart body 81, etc. The difference between this embodiment and the previous embodiment is that in this embodiment, the cart body 81 includes a support portion 815, and the animal carrier 82 is fixed by engaging with a connecting structure 816 (for example, a connecting buckle) installed on the support surface 815A of the support portion 815 via a connecting structure (which will be further described below) installed on the outside of the bottom surface of the housing, thereby stably attaching to the cart body 81.

[0066] As shown in Figures 8C and 8D, the detailed structures of the connection structure 825 for the animal carrier 82 and the connection structure 816 for the cart body 81 of the animal transport cart 8 of this embodiment are shown. As shown in the figures, in this embodiment, the animal carrier 82 includes a housing 821 and a bracket device 822, where the bracket device 822 includes a first bracket 8221 and a second bracket 8222 that are provided around the outer edge of the housing 821 and whose contours correspond to the outer edge of the housing 821. The first bracket 8221 and the second bracket 8222 are connected to each other to constitute the bracket device 822, and the bracket device 822 is coupled to the housing 821 outside of the housing 821. In this embodiment, the animal carrier 82 does not have to include a third bracket, which is advantageous for directly joining the housing 821 to the support portion 815 of the cart body 81. However, the disclosure is not limited thereto. In other embodiments, a third bracket may be installed at the bottom of the housing 821 of the animal carrier 82, that is, the structure and configuration of the animal carrier is the same as in the embodiment described above.

[0067] In this embodiment, the animal carrier 82 includes a connecting structure 825, which is installed in the center of the bottom surface outside the housing 821. The connecting structure 825 includes a cylindrical buckling portion 8251 and an annular joint portion 8252 surrounding the outer circumference of the cylindrical buckling portion 8251. The cart body 81 includes a connecting structure 816 (e.g., a connecting buckle), which includes a buckle fixing seat 8161 and a lid 8162. The buckle fixing seat 8161 is installed in the center of the support portion 815 and is connected to the connecting structure 825 via a through-opening 8151 in the support surface (top surface) 815A of the support portion 815 and fastened with a buckle. That is, in this embodiment, the connecting structure 825 of the animal carrier 82 is a male buckle structure, and the connecting structure 816 of the support portion 815 is a female buckle structure, and the two can be matched and fastened with buckles to connect them. The shape of the cover 8162 of the connection structure 816 corresponds to the buckle fixing seat 8161 and is connected to the buckle fixing seat 8161 to define a storage space, thereby housing the main structure and components of the connection structure 816.

[0068] As shown in Figures 8D and 8E, the connection structure 816 includes a pair of unlocking structures 8164 and a pair of interference structures 8165 corresponding to each unlocking structure 8164. Each unlocking structure 8164 includes an operating section 8164A, a pair of connecting arms 8164B, and a pair of stopper sections 8164C. Each interference structure 8165 includes a first interference structure 8165A and a second interference structure 8165B. The operating section 8164A is located on the operating surface (bottom surface) 815B of the support section 815 and is partially exposed outside the cover 8162 of the buckle fixing seat 8161, which is advantageous for user operation. A pair of connecting arms 8164B are located at both ends of the operating section 8164A. The connecting arms 8164B are elastic, which allows them to always remain in contact with the annular joint 8252 of the connecting structure 825. This connects the housing 821 to the support section 815 and stably connects the animal carrier 82 to the cart body 81. A pair of stopper sections 8164C are formed between the operating section 8164A and the connecting arms 8164B, respectively, and they abut against the first interference structure 8165A of the connecting structure 816. A portion of the connecting arm 8164B abuts against the second interference structure 8165B, and its connecting end abuts against the annular joint 8252 of the connecting structure 825 when the animal carrier 82 is connected to the cart body 81.

[0069] According to this embodiment, when attempting to detach the animal carrier 82 from the cart body 81, the user presses the operating portion 8164A of a pair of unlocking structures 8164 of the connecting structure 816. Since the unlocking structure 8164 is in contact with the second interference structure 8165B at a part of its connecting arm 8164B and with the first interference structure 8165A at its stopper portion 8164C, when the pair of operating portions 8164A receive a pressing force directed toward each other, the stopper portion 8164C and the connecting arm 8164B are affected by the first interference structure 8165A and the second interference structure 8165B, respectively. As a result, the connecting end of the connecting arm 8164B moves away from the connecting structure 816 and exits from the annular connecting portion 8252, that is, the connecting structure 825 and the support portion 815 are separated, and the animal carrier 82 can be removed from the cart body 81.

[0070] Optionally, in this embodiment, mutually engaging magnetic elements can be further installed between the cylindrical buckling portion 8251 of the connecting structure 825 and the lid 8162 (or between the buckling portion 8251 and the lid 8162), and the connecting structure 825 of the animal carrier 82 and the connecting structure 816 of the support portion 815 can be quickly aligned and connected by the magnetic attraction between the mutually cooperating magnetic elements.

[0071] As shown in Figures 9A and 9B, they show schematic external views of an animal transport cart 9 according to one embodiment of the present disclosure from different perspectives. The animal transport cart 9 of this embodiment includes a cart body 91 and an animal carrier 92, the animal carrier 92 being detachably connected to the cart body 91. In this embodiment, the cart body 91 has a structure and configuration similar to the cart body described above, and includes a cart handle 911, a mounting layer 912, a frame vertical rod 913 connecting the cart handle 911 and the mounting layer 912, a wheel member 914 installed at the bottom of the cart body 91, and a support part 915, etc. In this embodiment, the animal carrier 92 is similarly fixed to the cart body 91 by a connecting structure (described further below) installed at the bottom of the housing, and buckled to a connecting structure installed on the top surface (support surface) 915A of the support part 915, thereby stably attaching it to the cart body 91. The difference between this embodiment and the previously described embodiment is that in this embodiment, the connection structure of the support portion 915 is a rotating buckle 916, and the rotating buckle 916 is provided on the support portion 915 and a part of it is exposed on the bottom surface (operating surface) 915B of the support portion 915, which is advantageous for user operation. By operating and rotating the rotating buckle 916, the user fastens the buckle to the connection structure at the bottom of the housing 921 of the animal carrier 92 (as will be further explained below), thereby stably attaching the animal carrier 92 to the cart body 91.

[0072] As shown in Figures 9C and 9D, they show schematic external views of the animal carrier 92 of this embodiment from different perspectives. In this embodiment, the animal carrier 92 includes a housing 921 and a bracket device 922, where the bracket device 922 includes a first bracket 9221 and a second bracket 9222 that are circumferentially mounted on the outer edge of the housing 921 and whose contours correspond to the outer edge of the housing 921. The first bracket 9221 and the second bracket 9222 are connected to each other to constitute the bracket device 922, and the bracket device 922 is coupled to the housing 921 outside of the housing 921. In this embodiment, the animal carrier 92 does not have to include a third bracket, so that the housing 921 is directly joined to the support portion 915 of the cart body 91 at its bottom surface 921B. However, the disclosure is not limited thereto. In other embodiments, a third bracket may be installed on the bottom of the housing 921 of the animal carrier 92, i.e., the structure and configuration are the same as those of the animal carrier in the embodiment described above.

[0073] In this embodiment, the animal carrier 92 has a connecting structure 925 formed in the center of the bottom of the housing 921. As shown in the figure, the connecting structure 925 has a "cross-shaped" structure on the mounting surface 921A of the housing 921, and is composed of a recess 9251 formed on the mounting surface 921A of the housing 921 and a through-hole 9252 that penetrates the bottom of the housing 921, which intersects and thus has a "straight-line" structure on the bottom surface 921B of the housing 921. The animal carrier 92 receives the connecting projection 9162 (shown in Figure 9E) that protrudes from the top surface (support surface) 915A of the support part 915 at the through-hole 9252 of this "straight-line" structure, and is further stably connected to the support part 915 of the cart body 91 by being fastened with a buckle.

[0074] As shown in Figures 9F and 9G, they represent an exploded schematic and partial cross-sectional schematic of the support section 915 of the animal transport cart 9 of this embodiment, respectively, and are used to explain the detailed structure and operation of the rotating buckle 916 of the cart body 91. The rotating buckle 916 includes an inner rod 9163 that passes through the support section 915, an outer tube 9164 sleeved to the outside of the inner rod 9163, and an elastic element 9165 sleeved between the inner rod 9163 and the outer tube 9164. The inner rod 9163 has a "T-shaped" structure in longitudinal cross-section, and one end (bottom end) extends from the bottom surface (operating surface) 915B of the support section 915 and is connected to a knob 9161, which is exposed on the bottom surface 915B of the support section 915 to assist the user in rotating it. The other end (top end) of the inner rod 9163 is connected to a connecting projection 9162 which has a "straight-line" structure, and the connecting projection 9162 can protrude from the top surface 915A of the support part 915 and is used for locking and positioning the housing 921 of the animal carrier 92. In this embodiment, the inner rod 9163 can be rotated and moved relative to the outer tube 9164 by the rotation of the knob 9161, that is, the inner rod 9163 can rotate relative to the outer tube 9164 and move up and down relative to the outer tube 9164, forming a structure that can move up and down together with the outer tube 9164. The elastic element 9165 provides a driving force that generates the maximum relative movement of the inner rod 9163 relative to the outer tube 9164. In this embodiment, a sleeve 9151 is formed at a position corresponding to the rotating buckle 916 of the support part 915, and it shields the elastic element 9165 of the rotating buckle 916.

[0075] As shown in Figures 9G to 9I, the rotating buckle 916 includes a locking member 9163A, which may be, for example, a plug independent of the inner rod 9163, or a projection formed on the rod body of the inner rod 9163. A positioning groove 9164A is formed in the tube wall of the outer tube 9164, penetrating the tube wall, and the size of the locking member 9163A is adapted to the width of the positioning groove 9164A so that it can move within the positioning groove 9164A. In this embodiment, the positioning groove 9164A is a roughly "figure 7" structure, composed of a vertical groove 9164A1, a horizontal groove 9164A2, and a positioning end 9164A3 connected together. As the inner rod 9163 moves upward from its lowest position on the outer tube 9164, the locking member 9163A can move upward in the corresponding vertical groove 9164A1 of the positioning groove 9164A. The inner rod 9163 is driven to rotate by the rotation of the knob 9161, enters the horizontal groove 9164A2, and continues to move laterally in the horizontal groove 9164A2 in accordance with the rotation of the knob 9161, finally entering the positioning end 9164A3 and being positioned therein. At this time, when the movement stroke of the inner rod 9163 relative to the outer tube 9164 reaches its maximum and the locking member 9163A is positioned at the positioning end 9164A3, the inner rod 9163 is fixed to the outer tube 9164. Furthermore, since the inner rod 9163 is fixedly connected to the knob 9161, when the user pushes the knob 9161 upward, the inner rod 9163 can be driven to move upward, and at the same time, the locking member 9163A can be driven to move upward together to the top of the vertical groove 9164A1. Next, when the user rotates the knob 9161, driving the inner rod 9163 to rotate in the same direction, the locking member 9163A can enter the horizontal groove 9164A2 and move laterally to the end of the horizontal groove 9164A2, thereby preventing the user from rotating the knob 9161 further. At this time, the connecting projection 9162 rotates from its original position at the through-hole 9252 of the connecting structure 925 and not connected to the animal carrier 92 to the position of the recess 9251. When the user stops applying force to the knob 9161, the inner rod 9163 is driven and reset by the elastic force of the elastic element 9165.

[0076] As shown in Figures 9G and 9H, the top end of the inner rod 9163 of the rotating buckle 916 is a connecting projection 9162 having a "straight-line" structure (i.e., the connecting projection 9162 shown in Figure 9E), and the connecting projection 9162 can extend from a through-hole 9252 on the mounting surface 921A of the housing 921 of the animal carrier 92 as the inner rod 9163 moves upward (i.e., the connecting projection 9162 is joined to the through-hole 9252 of the matching connecting structure 925 and is higher than the bottom mounting surface 921A of the housing 921). When the user rotates the knob 9161 (for example, by 90 degrees), the connecting projection 9162 is driven to rotate synchronously (for example, by another 90 degrees), and then it can be brought into contact with the recess 9251 of the connecting structure 925, fixing and positioning the housing 921 relative to the support 915, and completing the cooperative connection between the animal carrier 92 and the cart body 91. On the other hand, when the user wants to release the cooperative connection between the animal carrier 92 and the cart body 91, the user pushes the knob 9161 upward again to drive the inner rod 9163 upward and move it away from the recess 9251, and then rotates the knob 9161 (for example, by 90 degrees), drives the connecting projection 9162 to rotate synchronously (for example, by another 90 degrees), and inserts it above the through-hole 9252, allowing the inner rod 9163 to reach its movable position. Since the connecting projection 9162 is located above the through-hole 9252 and is not connected to the animal carrier 92, when the user stops applying force to the knob 9161, the inner rod 9163 is driven downward by the elastic force of the elastic element 9165 (at which point the connecting projection 9162 enters the through-hole 9252), releasing the lock of the housing 921 from the support portion 915, and separating the animal carrier 92 from the cart body 91, as shown in Figure 9I.

[0077] As shown in Figures 10A and 10B, these are schematic external views of an animal transport cart 10 according to one embodiment of the present disclosure. The animal transport cart 10 of this embodiment includes a cart body 101 and an animal carrier 102, the animal carrier 102 being detachably connected to the cart body 101. In this embodiment, the cart body 101 has a structure and configuration similar to that of the previously described embodiment, and includes a cart handle 1011, a mounting layer 1012, a frame vertical rod 1013 connecting the cart handle 1011 and the mounting layer 1012, and a wheel member 1014, etc. The animal carrier 102 includes a housing 1021 and a bracket device 1022. The difference between this embodiment and the previously described embodiment is that in this embodiment, a connection structure is formed on the outside of the bottom of the housing 1021 of the animal carrier 102, thereby stably connecting it to the connection structure on the top surface of the support portion 105 of the cart body 101 in a rail connection manner.

[0078] As shown in Figure 10B, at least one pair of guide grooves 1053 are provided as a connecting structure in the fixed base 1051 of the support portion 105, and a positioning portion 1054 is provided at a location close to the front end of the fixed base 1051. An operation key 1052 is provided on the side of the fixed base 1051 and is used by the user to operate the positioning portion 1054.

[0079] As shown in Figure 10C, it shows a schematic diagram of the structure of the animal carrier 102 in this embodiment. In this embodiment, the housing 1021 of the animal carrier 102 is, for example, rectangular, and is formed by surrounding the mounting surface with surrounding side walls, and the housing 1021 has opposing long sides and opposing short sides. The bracket device 1022 of the animal carrier 102 is provided around the outer edge of the housing 1021 and includes a first bracket 10221 and a second bracket 10222 whose contours correspond to the outer edge of the housing 1021, and it provides support force to the housing 1021 and increases the load-bearing strength of the animal carrier 102. In this embodiment, the animal carrier 102 is provided with a pair of guide rails 1023 as a connecting structure on the outside of the bottom surface 1021B of the housing 1021, and the guide rails 1023 protrude from the bottom surface 1021B of the housing and extend along the direction of the long side of the housing 1021 on the bottom surface 1021B. In this embodiment, each guide rail 1023 is composed of a plurality of guide rail segments that are separated from each other (in this embodiment, there are three guide rail segments 1023A1 to 1023A3), but the disclosure is not limited thereto. In other embodiments, alternatively, the guide rail 1023 may be formed as a single structure, as determined according to the actual application needs. The housing 1021 has at least one positioning groove 1024 formed on its bottom surface 1021B, the positioning groove 1024 is provided between a pair of guide rails 1023 and is installed at the front and rear ends of the bottom surface 1021B of the housing 1021 (i.e., each short side adjacent to the housing 1021).

[0080] As shown in Figures 10D and 10E, they show a schematic side cross-sectional view of the animal transport cart 10 of this embodiment and are used to illustrate the detailed structure of the operating key 1052 and positioning section 1054 of the support section 105. The positioning section 1054 includes a positioning projection 10541, an elastic element 10542, and a drive pin 10543. The free end of the positioning projection 10541 has a guide surface 10541A and is used to guide the housing 1021. The positioning groove 1024 of the housing 1021 is driven in one direction by the guide surface 10541A and is joined to the positioning projection 10541, preventing the housing 1021 from sliding out of the guide groove and falling off due to environmental disturbances. The other end of the positioning projection 10541 is connected to the elastic element 10542, which provides a restorative force to reset the positioning projection 10541. The drive pin 10543 is connected to the positioning projection 10541 and the operating key 1052. Specifically, as shown in Figure 10E, a guide groove 1052A with a slope is formed at the end of the operating key 1052, and the drive pin 10543 is located within the guide groove 1052A and can be displaced relative to the slope of the guide groove 1052A.

[0081] As shown in Figures 10D and 10E, when attempting to attach the animal carrier 102 to the cart body 101, a pair of guide rails 1023 (see Figure 10C) on the bottom surface 1021B of the housing 1021 of the animal carrier 102 are joined to a pair of guide grooves 1053 (Figure 10B) of the fixed base 1051 of the support part 105, and slide until positioned by the guides of the guide grooves 1053. The free end of the positioning projection 10541 has a unidirectional guide surface 10541A, and can be pressed by the movement of the housing 1021 toward the handle side, driving the positioning projection 10541 to be displaced downward. After the housing 1021 is positioned on the support part 105, it is driven by the elastic element 10542 to be pushed into the positioning groove 1024 of the housing 1021, engaging and locking into place. When removing the animal carrier 102 from the cart body 101, the user only needs to press the operation key 1052. The operation key 1052 is pressed and moves to its rear end, which is then linked with the drive pin 10543 of the positioning part 1054 by the guide groove 1052A. This drives the positioning projection 10541 downward and moves it out of the positioning hole 1024, releasing the lock on the animal carrier 102 at the support part 105. After releasing the lock between the animal carrier 102 and the cart body 101, the animal carrier 102 can be moved out of the support part 105 by utilizing the relative movement in the guide groove 1053 of the guide rail 1023.

[0082] In this embodiment, the bottom plate serves as the fixed base 1051 of the support section 105, a guide groove 1053 is formed in the bottom plate as a connecting structure, and the animal carrier 102 is connected to it by a guide rail 1023 at the bottom of the housing. In other embodiments, the support section 105 may consist of a bottom plate and surrounding side plates connected to the bottom plate, and may further include a top plate connected to the surrounding side plates to form a sealed, pull-out structure, and the guide groove may be selectively formed in the top plate, bottom plate, or side plate so as to stably connect with the corresponding connecting structure of the animal carrier housing 102. Alternatively, the peripheral walls of the animal carrier 102 may be made of a transparent, rigid or flexible material so as to allow the user to easily check the condition inside the animal carrier.

[0083] In this disclosure, the connection structures of the animal carrier 102 and the cart body 101 are not limited to the rails at the bottom of the housing and the guide grooves in the support section. For example, in other embodiments, a first magnetic element can be provided as a connection structure on the bottom or outside of the peripheral wall of the housing 1021, and a second magnetic element can be provided as a connection structure on the inside of the top or side plate of the support section 105 or on the fixed base. The magnetic attraction effect of the mutually engaging first and second magnetic elements can then be used to quickly align and stably connect the animal carrier 102 and the cart body 101 to each other.

[0084] In this disclosure, the height of the support section or support frame of the cart body of the animal transport cart can be adjusted to accommodate different animal carriers. Furthermore, the support section of the cart body of the animal transport cart is pivotable on the vertical frame rod so as to fold toward the vertical frame rod to facilitate the use and storage of the cart body, as described below.

[0085] As shown in Figure 11A, it shows a schematic side cross-sectional view of an animal transport cart 15 according to one embodiment of the present disclosure. The animal transport cart 15 includes a cart body 151 and an animal carrier 152. The animal carrier 152 is stably connected to the cart body 151 in a separable manner. In this embodiment, the cart body 151 has a structure and configuration similar to the cart body described above and includes a cart handle 1511, a mounting layer 1512, a frame vertical rod 1513 connecting the cart handle 1511 and the mounting layer 1512, and a wheel member 1514 provided at the bottom of the cart body 151. The animal carrier 152 has a structure and configuration similar to the embodiment described above and includes a housing and a bracket device. The difference between this embodiment and the previously described embodiment is that in this embodiment, the cart body 151 further includes an adjustment device 155, and the adjustment device 155 is connected to a support portion 1515 (e.g., a support frame) and a frame vertical rod 1513. Therefore, the height of the support portion 1515 of the cart body 151 at the frame vertical rod 1513 is adjustable, and the frame can be easily folded by rotating toward the frame vertical rod 1513.

[0086] More specifically, as shown in Figures 11B and 11C, they show partially exploded schematic diagrams of the animal transport cart 15 of this embodiment, respectively, and are used to explain the detailed structure of the adjustment device 155. As shown in the figures, a pair of frame vertical rods 1513 of the animal transport cart 15 are hollow structures having, for example, a rectangular cross-section, with guide grooves 1513A provided on their opposing inner sides, which are used to house and move the adjustment device 155 up and down. The adjustment device 155 includes an adjustment base 1551, an elastic element 1552, a gear member 1553, a connecting member 1554, and a fixing cover piece 1555. The adjustment base 1551 has a first housing section 1551A and a second housing section 1551B. The outer contour of the first housing section 1551A matches the contour of the frame vertical rod 1553 and is installed within the frame vertical rod 1553. The second housing portion 1551B is cylindrical and has a central pivot shaft 1551C. The second housing portion 1551B has multiple protrusions formed on its inner edge, thereby having an inner contour 1551B1 that matches the gear member 1553. The elastic element 1552 is sleeved to the central pivot shaft 1551C, with one end abutting against the inner surface of the second housing portion 1551B and the other end abutting against the gear member 1553, and is used to provide a restorative force for resetting each member. The gear member 1553 matches the inner contour 1551B1 of the second housing portion 1551B and engages with the multiple protrusions with its teeth. The connecting member 1554 covers the gear member 1553 and has a circular structure, with an extending connecting end 1554A that connects to the end of the short side of the support portion 1515 of the cart body. The fixed cover piece 1555 is locked to the connecting member 1554, sealing and protecting the components inside the adjustment device 155, and is used by the user to press the unlock button to activate the gear member 1553 and adjust the angle of the support part 1515.

[0087] As shown in Figure 11C, each of the pair of frame vertical rods 1513 of the animal transport cart in this embodiment is provided with an adjustment device 155. The adjustment device 155 is installed inside the frame vertical rod 1513 by a first housing portion 1551A, and the second housing portion 1551B of the adjustment device 155 protrudes outside the frame vertical rod 1513 from the guide groove 1513A, thereby allowing it to move up and down along the guide groove 1513A on the frame vertical rod 1513. In this embodiment, a positioning member 1556 is installed inside the first housing portion 1513A, and the positioning member 1556 exhibits a "Z-shaped" structure and is stably in contact with the inside of the first housing portion 1551A.

[0088] As shown in Figure 11D, it is a schematic partial cross-sectional view of the animal transport cart according to this embodiment and is used to explain the detailed structure and operation of the positioning member 1556 and the frame vertical rod 1513 of the adjustment device. In this embodiment, the positioning member 1556 has a "Z-shaped" structure and is stably in contact with the first housing portion 1551A of the adjustment device. The positioning member 1556 may be a "Z-shaped" sheet made of an elastic material, with a projection formed at one end to form the positioning end 1556A, and the other end in contact with the inner wall of the first housing portion 1551A to form the contact end 1556B. In this embodiment, the frame vertical rod 1513 is, for example, a hollow structure having a rectangular cross-section, with a plurality of positioning holes 1513B1 to 1513B4 formed on one side (for example, the side approaching the cart handle), and the positioning holes 1513B1 to 1513B4 are through-holes that penetrate the rod wall. In this embodiment, the positioning end 1556A of the positioning member 1556 can be inserted into and fixed in each positioning hole 1513B1 to 1513B4, thereby positioning the support portion at each corresponding height position.

[0089] As shown in Figures 11A and 11B, in this embodiment, adjustment devices 155 are installed on each of the pair of frame vertical rods 1513 of the cart body 151 of the animal transport cart 15. The first housing portion 1551A of the adjustment device 155 is positioned inside the frame vertical rod 1513, and the second housing portion 1551B and connecting member 1554 extend from the guide groove 1513A of the frame vertical rod 1513 and are connected to the support portion 1515 of the cart body 151. The adjustment device 155 has a first housing portion 1551A located within the frame vertical rod 1513, and its second housing portion 1551B located within the guide groove 1513A moves up and down, so that the positioning end 1556A of the positioning member 1556 in the first housing portion 1551A fixes the positioning hole in the frame vertical rod 1513, thereby allowing the support portion 1515 and the animal carrier 152 mounted thereon to be adjusted to the appropriate height and then locked in place. Furthermore, the meshing action and positioning of the gear member 1553 in the adjustment device 155 with respect to the inner contour 1551B1 of the second housing portion 1551B allows the cart handle 1511 to rotate around the direction of the connection line at the connection point between the cart handle 1511 and the frame vertical rod 1513. This allows the support portion 1515 and the animal carrier 152 mounted thereon to be driven to rotate upward or downward to an appropriate angle and then positioned. Moreover, after removing the animal carrier 152 from the cart body 151, the support portion 1515 can be rotated downward to a direction perpendicular to the ground and folded, which is advantageous for storing the cart body.

[0090] This embodiment illustrates that the adjustment device 155 can perform height and angle adjustments (for example, the adjustment device 155 shown in Figure 11B), but the disclosure is not limited thereto. In other embodiments, the adjustment device may include only the angle adjustment mechanism shown in Figure 11C, or only the height adjustment mechanism shown in Figure 11D, depending on the actual application.

[0091] Based on the above, this disclosure provides an animal transport cart that allows for easy, convenient, and stable attachment and securing of an animal carrier, while also providing the user with sufficient storage space for placing items.

[0092] The support structure of this disclosure allows the mounting height of the animal carrier in the animal transport cart to be adjusted according to the actual application needs. Furthermore, the support structure of the animal transport cart can rotate around the direction of the connection line at the connection point between the frame vertical rod and the cart handle, allowing the angle of the animal carrier fixed on it to be adjusted, which is advantageous for storing the cart body after removing the animal carrier and has high potential for application.

[0093] All parameters, sizes, materials, and structures described herein are illustrative descriptions, and their actual parameters, sizes, materials, and / or structures will be determined according to the specific application or the application suggested by using this disclosure.
