[0167] First Embodiment

[0168] As shown in Figure 1, the first embodiment of the present invention provides a carrying device 10, which includes a body 100, a base 200, and a first connecting mechanism 300. The body 100 and the base 200 are detachably connected to form a accommodating space 101 for accommodating a pet (see Figure 3). The first connecting mechanism 300 is disposed between the body 100 and the base 200 to achieve the detachable connection between them. The body 100 and the base 200 are connected to form the housing of the carrying device 10.

[0169] It should be noted that the following description of the embodiments will use directional terms such as "front," "rear," "left," "right," "up," and "down." In this embodiment, the directional terms "front," "rear," "left," "right," "up," and "down" of the carrying device 10 correspond to the "front," "rear," "left," "right," "up," and "down" directions of the vehicle (as shown in Figure 13). The "front," "rear," "left," "right," "up," and "down" directions are schematically indicated by arrows F, B, L, R, U, and D in the figure. These directional terms are only used to make the technical solution of the embodiments of the present invention clearer and are only used to indicate the relative positional relationship between different components. They are not used to unduly limit the scope of protection of the present invention.

[0170] As shown in Figure 2, the main body 100 in this embodiment can switch between a closed state and an open state. For example, the main body 100 can be a foldable canopy to provide a shielding function. When the main body 100 is unfolded, it is in an unfolded state that provides shielding (this can be called the unfolded state). When the main body 100 is folded, it is in a folded state that does not provide shielding (this can be called the folded state). In this embodiment, the main body 100 can switch between a closed state as shown in Figures 1 and 5 and an open state as shown in Figure 6. When the main body 100 is in the closed state, as shown in Figures 1 and 5, the main body 100 generally presents a rectangular box-shaped structure. After the main body 100 is connected to the base 200, the accommodating space 101 is closed. When the main body 100 is in the open state, at least a portion of the main body 100 is gathered together, the overall volume becomes smaller, and after the main body 100 is connected to the base 200, the accommodating space 101 is opened, allowing pets to enter and exit. It should be understood that the open state of the body 100 can include a fully open state or a half-open state. For example, in this embodiment, when both the left and right sides of the body 100 converge and fold towards the center, the body 100 is in a fully open state, while when only one side of the body 100 converges and folds towards the center (not shown), the body 100 is in a half-open state. In other embodiments, other folding methods may also be used, such as one side of the body 100 moving and folding towards the other side instead of converging and folding towards the center. In other embodiments, a portion of the body 100 may form a window structure, and the body 100 can switch between an open and closed state by opening or closing the window structure; this is not limited here. Of course, in other embodiments, the body 100 can be a common, fixed-shape body 100, such as a hexahedral body 100.

[0171] As shown in Figure I, the height of the body 100 in this embodiment is not less than half of the length of the body 100. It should be noted that, in this embodiment, the height of the body 100 corresponds to the dimension of the body 100 in the vertical direction, and the length of the body 100 corresponds to the dimension of the body 100 in the horizontal direction.

[0172] In this embodiment, the main body 100 specifically includes a mounting base 110, multiple support rods 120, and a cover 130. At least one end of each support rod 120 is connected to the mounting base 110, and the multiple support rods 120 and the mounting base 110 are connected to form the skeleton of the main body 100. The cover 130 is connected to the multiple support rods 120 to form a box-shaped structure with an open bottom. In one embodiment, as shown in Figures 3 and 4, each of the multiple support rods 120 is a U-shaped rod, and each U-shaped rod includes a top rod 121 and two side rods 122 connected to both ends of the top rod 121. The main body 100 includes two oppositely arranged mounting bases 110, and the ends of the two side rods 122 away from the top rod 121 are respectively connected to the two mounting bases 110. In this embodiment, the cover 130 is made of fabric. Of course, in other embodiments, the cover 130 can also be made of plastic or rubber, etc.

[0173] As shown in Figures 3 and 4, the multiple support rods 120 may include a first support rod 120a and a second support rod 120b. For example, in this embodiment, the body 100 may include two first support rods 120a and two second support rods 120b. The first support rod 120a is rotatably connected to the mounting base 110, and the first support rod 120b is fixedly connected to the mounting base 110. In this embodiment, the two ends of the two first support rods 120a are rotatably connected to the two mounting bases 110 respectively, and the two ends of the two first support rods 120b are fixedly connected to the two mounting bases 110 respectively. In this embodiment, the two second support rods 120b are arranged adjacent to each other, and the two first support rods 120a are located on both sides of the two second support rods 120b respectively. When the body 100 is in the closed state shown in Figure 5 (which can also be called the unfolded state in this embodiment), the height of the highest point of the two second support rods 120b is higher than the height of the highest point of the two first support rods 120a. Specifically, when the main body 100 is in the closed state as shown in Figure 5, the two first support rods 120b are approximately perpendicular to the two first support rods 120a, that is, the two second support rods 120b are basically in a vertical state, and the two first support rods 120a are basically in a horizontal state. In this embodiment, the rotation range of the first support rod 120a is approximately 90 degrees, and the main body 100 can switch between the open and closed states. In other embodiments, the rotation range of the first support rod 120a can be 120 degrees or 180 degrees, or other angles. Furthermore, in this embodiment, the two second support rods 120b are spaced apart and fixed in position relative to the mounting base 110, and the cover 130 connected to the two second support rods 120b will remain in an open state. In other embodiments, the main body 110 may have only one second support rod 120b or more than two second support rods 120b. In this embodiment, when the main body 100 is in the closed state, the two first support rods 120a can rotate 180 degrees relative to each other, that is, the two first support rods 120a are basically in a horizontal state. The two first support rods 120a simultaneously drive the cover 130 connected to them to unfold, and the cover 130 and the base 200 enclose the accommodating space 101. When the main body 100 is in the open state, the two first support rods 120a can rotate relative to each other to be relatively parallel, that is, the two first support rods 120a are basically in a vertical state, and the two first support rods 120a simultaneously drive the cover 130 connected to them to fold, forming an opening between the cover 130 and the base 200.

[0174] Of course, in other embodiments, the body 100 may not include the two second support rods 120b, but only the first support rod 120a. For example, when the body 100 is in the closed state, the two second support rods 120a are basically distributed at 180 degrees and are in a horizontal state. When it is necessary to switch the body 100 to the open state, one of the first support rods 120a rotates 180 degrees toward the other first support rod 120a, so that the two first support rods 120a move closer to each other, causing the cover 130 to fold down. As another example, when the body 100 is in the open state, the two first support rods 120a are basically parallel and are in a vertical state. When it is necessary to switch the body 100 to the closed state, at least one first support rod 120a rotates 90 degrees and is in a roughly horizontal state, causing the cover 130 to fold down.

[0175] In one embodiment, as shown in FIG4, the main body 100 may further be provided with multiple support bars 140 between the first support rod 120a and the second support rod 120b. The cover 130 is connected to the multiple first support rods 120b, the multiple first support rods 120a, and the multiple support bars 140. The width of the support bars 140 in the left-right direction may be less than the width of the support rods 120 in the left-right direction. The support bars 140 may be made of materials such as metal or plastic. The support bars 140 are also U-shaped rod structures. In this embodiment, there are four support bars 140, of which two support bars 140 are provided between the first support rods 120a and the second support rod 120b on one side, and the other two support bars 140 are provided between the first support rods 120a and the second support rod 120b on the other side. In this embodiment, the cover 130 covers the multiple first support rods 120b, the multiple first support rods 120a, and the multiple support bars 140. It should be noted that the cover 130 can conceal at least a portion of the support rod 120 and the mounting base 110. For ease of understanding, Figures 1 and 13 of this embodiment use dashed lines to simply illustrate the partial structure inside the cover 130 of the first support rod 120a, the second support rod 120b, and the mounting base 110. In other embodiments, the support rod 120 or the mounting base 110 may also be exposed outside the cover 130.

[0176] Furthermore, the two support bars 140 near the second support rod 120b are referred to as the first support bars 140a, and the two support bars 140 near the first support rod 120a are referred to as the first support bars 140b. Referring to Figure 5, the end of the first support bar 140a near the mounting base 110 is designated as the first proximal end 140a1, the end of the first support bar 140a away from the mounting base 110 is designated as the first distal end 140a2, the end of the second support bar 140b near the mounting base 110 is designated as the second proximal end 140b1, and the end of the second support bar 140b away from the mounting base 110 is designated as the first distal end 140b2. The distance between the first proximal end 140a1 and the first distal end 140a2 of the first support bar 140a is greater than the distance between the second proximal end 140b1 and the second distal end 140b2 of the second support bar 140b. As shown in Figure 5, when the main body 100 is in the closed state, the height of the highest point of the second support rod 120b (i.e., the end of the second support rod 120b furthest from the mounting base 110) is higher than the height of the highest point of the first support bar 140a (i.e., the first distal end 140a2), and the height of the highest point of the first support bar 140a (i.e., the first distal end 140a2) is higher than the highest point of the second support bar 140b (i.e., the second distal end 140b2). When the main body 100 is in the open state, the height of the highest point of the first support bar 140a (i.e., the first distal end 140a2) is basically level with the height of the highest point of the first support rod 120b, and the heights of the highest points of the two second support bars 140b (i.e., the second distal ends 140b2) are between the heights of the highest points of the second support rod 120b and the highest point of the first support rod 120a. The support bar 140 provides auxiliary support to the cover 130, making the overall shape of the body 100 more three-dimensional and upright when unfolded. In this embodiment, the support bar 140 is positioned relative to the cover 130 and can move with the cover 130. When the cover 130 rotates to unfold or retract, it can drive the support bar 140 to rotate. For example, the cover 130 has multiple channels (not shown), and multiple support bars are respectively inserted into one of the multiple channels. In some embodiments, the support bar 140 can also be rotatably connected at both ends to the mounting bases 110 on both sides, and the support bar 140 can rotate with the rotation of the first support rod 120a relative to the second support rod 120b, thereby realizing the folding and unfolding of the body 100.

[0177] Please refer to Figures 3 and 4 together. Taking one mounting base 110 as an example, its structure is described in detail. The mounting base 110 is generally a flat shell structure with an inverted V-shape. The mounting base 110 includes a top surface 111 and a bottom surface 112 opposite to each other. One end of each of the two second support rods 120b is connected to the top surface 111. The mounting base 110 also includes a first clearance groove 113 and a second clearance groove 114, which are located on opposite sides of the mounting base 110 in the left-right direction. The body 100 also includes two pivot seats Y, which are respectively disposed in the first clearance groove 113 and the second clearance groove 114. One first support rod 120a is connected to one of the pivot seats Y, and the other first support rod 120a is connected to the other pivot seat Y. The two pivot seats Y are pivotally connected to the mounting base 110. Thus, the first support rod 120a is rotatably connected to the mounting base 110 through the first pivot seat Y, and the second support rod 120a is rotatably connected to the mounting base 110 through the other pivot seat Y.

[0178] As shown in Figure 5, when the main body 100 is in the closed state, the bottom surfaces of the two first support rods 120a are basically flush with the bottom surface 112 of the mounting base 110. As shown in Figure 6, when the main body 100 is in the open state, both first support rods 120a rotate to be above the bottom surface 112 to form an opening for the pet to enter and exit.

[0179] In one embodiment, as shown in Figures 4 to 6, at least the portions of the two second support rods 120b and the two first support rods 120a that are connected to the mounting base 110 extend obliquely in the left-right direction of the body 100. More specifically, the ends of the two second support rods 120b connected to the same mounting base 110 extend obliquely toward each other to the mounting base 110, and the ends of the two first support rods 120a connected to the same mounting base 110 extend obliquely toward each other to the mounting base 110. This arrangement makes the portions of the two first support rods 120b and the two first support rods 120a connected to the mounting base 110 relatively compact, thus reducing the need for a large volume in the mounting base 110. At the same time, it can ensure that the portions of the two second support rods 120b and the two first support rods 120a that are far away from the mounting base 110 are relatively far apart and have a large gap, which can effectively support the cover 130, so that the body 100 and the base 200 form a large accommodating space 101.

[0180] When a pet needs to enter or exit the carrier 10, the first support rod 120a located on one or both sides of the mounting base 110 can be moved closer to the adjacent second support rod 120b, thus switching from the state shown in Figure 5 to the state shown in Figure 6. Simultaneously, the first support rod 120a on one or both sides of the mounting base 110 will cause the connected cover 130 to fold together, creating an opening on one or both sides of the main body 100. Therefore, the pet can enter or exit the carrier 10 through this opening.

[0181] Specifically, as shown in Figures 7 and 8, the base 200 includes a housing with a first cover 210 and a second cover 220. The first cover 210 is a generally rectangular concave housing structure. The first cover 220 is an annular housing structure. In this embodiment, the second cover 220 is a generally rectangular annular structure with the same outer contour as the first cover 210, and the second cover 220 is fixed above the first cover 210. The housing has a recessed space that can be used to place a cushion (not shown in the figures) to improve the pet's riding comfort.

[0182] Of course, in other embodiments, the first cover 210 and the second cover 220 may also be of other shapes. For example, the first cover 210 may have a bottom wall and a side extending upward from the bottom wall; the first cover 210 may be a generally elliptical concave shell structure; and the second cover 220 may be a generally elliptical annular structure with the same outer contour as the first cover 210. The present invention is not limited thereto. In other embodiments, the shell of the base 200 may be a one-piece structure, and may not be composed of the first cover 210 and the first cover 220. This is not a limitation.

[0183] In one embodiment, as shown in FIG. 7, the base 200 may further include a support member 230, which is located within the housing and provides cushioning support for the pet. More specifically, the support member 230 is located above the bottom wall of the first cover 210. In this embodiment, the support member 230 is located between the first cover 210 and the second cover 220, and in this embodiment, the support member 230 is a plate-like structure approximately the same size as the first cover 210. The aforementioned pad can be placed on the support member 230.

[0184] Optionally, the first cover 210 may be made of materials such as foam and fabric. The second cover 220 may be made of materials such as plastic or foam. The support member 230 may be a foam, made of materials such as ethylene-vinyl acetate copolymer (EVA), but the present invention is not limited thereto.

[0185] In this embodiment, the accommodating space 101 of the supporting device 10 includes a recessed space in the body 100 and a recessed space in the base 200. The accommodating space 101 of the supporting device 10 is mainly located in the body 100, that is, the size of the recessed space in the body 100 roughly determines the size of the accommodating space 101 of the supporting device 10. The base 200 mainly serves to support the pet and cooperate with the body 100. Optionally, the height of the recessed space of the base 200 (i.e., the vertical distance H1 from the highest point of the second cover 220 to the highest point of the support 230 (as shown in Figure 11)) does not exceed 25% of the overall height of the accommodating space 101 (i.e., the vertical distance H2 from the highest point of the inner surface of the body 100 to the highest point of the support 230 (as shown in Figure 11)). Preferably, the height H1 of the base 200 is preferably 5% to 15% of the overall height H2 of the support device 10, for example, 10%. It is understood that when the height of the recessed space is zero, there is no upward-extending enclosure around the base 200 (equivalent to the portion of the base 200 protruding above the support 230). The base 200 of the support device 10 in this embodiment does not have a high side enclosure like many other support devices 10 on the market. Thus, when the body 100 is separated from the base 200, more of the interior of the base 200 can be exposed. This design facilitates the movement of pets onto or off the base 200, making it especially suitable for injured pets. They can enter and exit the base 200 without having to climb over the high side barriers, allowing injured pets to easily enter or leave the base 200, or making it easier for caregivers to lift injured pets into or out of the base 200.

[0186] In this embodiment, as shown in FIG7, the base 200 may further include a fixing seat 240. The fixing seat 240 is connected to the upper part of the housing. In this embodiment, there are two fixing seats 240, which are respectively disposed on opposite sides of the housing. Specifically, the two fixing seats 240 are disposed on opposite sides of the second cover 220 in the direction of its short side (for example, at the midpoint of the two opposite long sides of the second cover 220). The upper part of the housing has an upwardly protruding limiting ridge 221. Specifically, the second cover 220 is provided with an upwardly protruding limiting ridge 221. In this embodiment, there are two limiting ridges 221, both of which are U-shaped ridges. One limiting ridge 221 is disposed on the left side of the two fixing seats 240, and the other limiting ridge 221 is disposed on the right side of the two fixing seats 240. Each limiting protrusion 221 near the ends of the two fixing seats 240 forms a relief slope 2211, for example, the relief slope 2211 is adapted to the two inclined extending sides of the mounting seat 110 connected to the bottom surface of the mounting seat 110. In some non-limiting embodiments, the fixing seat 240 includes a housing portion 241 and a fixing portion 242 connected to each other. The housing portion 241 is generally a square housing structure. The housing portion 241 has an opening 2411 on the side of the housing portion 241 facing inward to the base 200 so as to expose the groove 3211 of the second connector 320 (see below). The bottom edge of the housing portion 241 bends outward to form the aforementioned fixing portion 242. The fixing portion 242 is used to fix the second cover 220 by means of, for example, welding or fastener connection. In other embodiments, the groove 3211 may also be provided on the side of the fixing part 242 facing the outside of the base 200, and correspondingly, the side of the housing part 241 facing the outside of the base 200 has an opening 2411, and the hook part 311 may extend inward to the inside of the body 100. In some embodiments, the limiting protrusion 221 of the housing may be one or more, for example, one limiting protrusion may be arranged in a ring shape or one limiting protrusion may be provided on one side of the upper part of the housing, or three or more limiting protrusions may be arranged at intervals on the housing.

[0187] In one embodiment, as shown in Figures 8 to 10, the base 200 further includes a tubular structure 250. A receiving space 102 for accommodating the tubular structure 250 is formed between the support member 230 and the housing. More specifically, the receiving space 102 is formed between the support member 230 and the first cover 210. The tubular structure 250 is disposed at the bottom of the support member 230 to strengthen the base 200. Specifically, the tubular structure 250 includes a connecting frame 251. The connecting frame 251 is generally a rectangular frame structure and is fixed to approximately the center of the bottom surface 112 of the support member 230. The tubular structure 250 also includes a reinforcing tube 252. The reinforcing tube 252 extends generally along a direction parallel to the short side of the support member 230, or, at least a portion of the reinforcing tube 252 extends in a front-rear direction. There are two reinforcing tubes 252. The first ends 2521 of the two reinforcing tubes 252 are connected to opposite sides of the connecting frame 251, and the second ends 2522 of the two reinforcing tubes 252 extend upward to connect to the second connecting members 320 (see below) of the two first connecting mechanisms 300. The pipe structure 250 also includes a connecting tube 253. The connecting tube 253 extends generally along the long side parallel to the support member 230, or at least a portion of the connecting tube 253 extends in the left-right direction. There are two connecting tubes 253. One end of the two connecting tubes 253 is connected to the other opposite sides of the connecting frame 251, and the other end of the two connecting tubes 253 extends away from the connecting frame 251. In this way, the reinforcing tubes 252 and the connecting tubes 253 reinforce the base 200 from the longitudinal and transverse directions, respectively, improving the support strength of the base 200.

[0188] In one embodiment, as shown in Figures 8 and 9, the base 200 may further include supporting protrusions 255. There are two supporting protrusions 255, each located near one of the two short sides of the base 200. The two supporting protrusions 255 connect to the support member 230. The cover 210 has through-holes 211 corresponding to the positions of the two supporting protrusions 255. The two supporting protrusions 255 are exposed outside the receiving space 102 through the two through-holes 211, thus providing support and stability for the entire supporting device 10. In this embodiment, the other ends of the two connecting tubes 253 extend towards the short side near the supporting device 10. At least a portion of the two connecting tubes 253 is hidden within the side of the two supporting protrusions 255 facing the support member 230. As shown in Figure 9, the reinforcing tube 252 extends in the front-rear direction and is approximately located at the center line of the support device 10 in the left-right direction, and the connecting tube 253 extends in the left-right direction and is approximately located at the center line of the support device 10 in the front-rear direction. It should be understood that the section line 0-0 corresponding to the sectional view shown in Figure 10 is the center position of the base 200 in the front-rear direction, and the section lines PP and QQ corresponding to the sectional views in Figures 11 and 12, respectively, are the center positions of the base 200 in the left-right direction. As shown in Figure 10, in this embodiment, the support member 230 and the tube structure 250 are connected by fasteners such as screws.

[0189] It should be noted that, in this embodiment, the pipe structure 250 includes a connecting frame 251, two reinforcing pipes 252, and two connecting pipes 253, with the two reinforcing pipes 252 and the two connecting pipes 253 respectively connected to the four sides of the connecting frame 251. In other embodiments, the reinforcing pipes 252, connecting pipes 253, and connecting frame 251 can be selectively omitted. For example, the connecting frame 251 can be omitted, and the first ends of the two reinforcing pipes 252 can be directly connected to form an integral pipe, or one end of the two connecting pipes 253 can be directly connected to form an integral pipe. In this case, the two directly connected reinforcing pipes 252 can also be regarded as a single reinforcing pipe 252, or the two directly connected connecting pipes 253 can also be regarded as a single connecting pipe 253. Alternatively, both the connecting frame 251 and the connecting pipes 253 can be omitted.

[0190] In one embodiment, the base 200 may further include guide blocks 254. In this embodiment, there are two guide blocks 254, each fixed to one of the two connecting pipes 253. As shown in FIG9, the two guide blocks 254 have guide channels 2541 extending through both ends of them. The distance between the first ends 2541a of the two guide channels 2541 is less than the distance between the second ends 2541b of the two guide channels 2541. The first ends 2541a of the two guide channels 2541 are close to each other, while the second ends 2541b are far apart.

[0191] In this embodiment, as shown in Figures 8 and 9, the support member 230 may also be provided with a first storage groove 231 and a second storage groove 232. The first cover 210 has corresponding openable and closable first storage cover 212 and second storage cover 213 opposite to the first storage groove 231 and the second storage groove 232. The first storage groove 231 is positioned relative to the second storage groove 232 at its first end 2541a near the two guide channels 2541, and the second storage groove 232 is positioned relative to the first storage groove 231 at its second end 2541b near the guide channel 2541. In this embodiment, the first storage groove 231 and the second storage groove 232 are respectively adjacent to the two oppositely positioned sides of the support member 230.

[0192] In one embodiment, as shown in FIG8, the base 200 may further include a mating seat 260 and a locking member 270 for connection with the trolley 20 shown in FIG14 (see below for details). As shown in FIG8 and FIG9, the support member 230 has a mounting groove 233 corresponding to the center hole 2511 of the connecting frame 251, and the housing (e.g., the first cover 210) has a mounting opening (not shown) corresponding to the mounting groove 233. The mating seat 260 is installed into the mounting groove 233 through the mounting opening. The mating seat 260 is generally square block structure, and a square groove 261 is provided in the middle of the mating seat 260. The locking member 270 is disposed in the groove 261. In this embodiment, the locking member 270 has a rod structure and its two ends are respectively connected to the two side walls of the groove 261. In other embodiments, the engaging member 270 may also be a hook-shaped structure, a protrusion, a groove, or other structure, as long as it can be connected to the trolley 20.

[0193] Specifically, as shown in Figures 11 and 12, a first connecting mechanism 300 is disposed between the body 100 and the base 200. The first connecting mechanism 300 has a locked state and an unlocked state. When the first connecting mechanism 300 is in the locked state, the body 100 is allowed to switch between an open state (as shown in Figure 6) and a closed state (as shown in Figure 5) to open or close the accommodating space 101. When the first connecting mechanism 300 is in the unlocked state, the body 100 and the base 200 are detachable (as shown in Figure 12). The first connecting mechanism 300 includes a first connector 310 and a second connector 320. The first connector 310 is movably disposed on the body 100 and can switch between a locked position and an unlocked position. The second connector 320 is disposed on the base 200. When the first connecting member 310 is in the locked position (i.e., the first connecting mechanism 300 is in the locked state), the first connecting member 310 and the first connecting member 320 are locked together. When the first connecting member 310 is in the unlocked position (i.e., the first connecting mechanism 300 is in the unlocked state), the first connecting member 310 and the first connecting member 320 are disengaged, and the base 200 and the body 100 are detachably connected through the first connecting mechanism 300. Of course, in other embodiments, the positions of the first connecting member 310 and the second connecting member 320 can also be interchanged, that is, the first connecting member 310 can be movably disposed on the base 200, and the second connecting member 320 is not disposed on the body 100. In other words, the first connecting member 310 can be movably disposed on one of the base 200 and the body 100, and the second connecting member 320 is disposed on the other of the base 200 and the body 100. Optionally, when the first connector 310 is in the locked position, the first connector 310 and the first connector 320 can be engaged by insertion, snap-fit, or other methods that allow for quick assembly and disassembly.

[0194] In this embodiment, the first connecting mechanism 300 has two F1s, respectively located on opposite sides of the wood body 100 and the base 200 in the short-side direction. Of course, in other embodiments, the number and location of the first connecting mechanisms 300 can be adjusted as needed; for example, four first connecting mechanisms 300 can be provided on the four sides of the body 100 and the base 200. The structure of one of the first connecting mechanisms 300 is described below as an example:

[0195] In one embodiment, as shown in Figures 11 and 12, the first connecting mechanism 300 may further include a release member 330. In this embodiment, the first connecting member 310 and the release member 330 are connected and movably disposed within the mounting base 110. The release member 330 can be operated to move the first connecting member 310 to the unlocked position. In another embodiment, the first connecting mechanism 300 may further include a first reset member 340. The first reset member 340 is used to apply force to the release member 330 so that the release member 330 moves the first connecting member 310 to the locked position. In this embodiment, the first connecting member 310 and the release member 330 are integrally formed structures for connection. In other embodiments, they may be separate structures and connected by fasteners (not shown) or by drive grooves (not shown) and drive columns (not shown).

[0196] Specifically, as shown in Figures 11 and 12, the mounting base 110 has a mounting cavity 115, in which the first connecting member 310 and the releasing member 330 are at least partially movably mounted. The releasing member 330 includes a mounting portion 331 and a pressing portion 332 connected to each other. Both the mounting portion 331 and the pressing portion 332 are generally cylindrical, and the radial dimension of the mounting portion 331 is larger than the radial dimension of the pressing portion 332. Thus, a limiting step 333 is formed at the connection between the mounting portion 331 and the pressing portion 332. The side of the mounting base 110 facing the outside of the accommodating space 101 has an operating port 116 communicating with the mounting cavity 115, through which at least a portion of the pressing portion 332 is exposed for operation. One side wall of the mounting cavity 115 is provided with a limiting protrusion 117, which abuts against the limiting step 333 of the releasing member 330 to limit the movement of the releasing member 330 and prevent the releasing member 330 from sliding out through the operating port 116. The mounting part 331 has a mounting hole 3311 on the side facing away from the operating port 116, and the first reset member 340 is at least partially installed in this mounting hole 3311. Specifically, the first reset member 340 is a spring. The bottom wall of the mounting hole 3311 is provided with a first limiting part 3312, and the wall of the mounting cavity 115 facing the operating port 116 is provided with a second limiting part 118 opposite to the first limiting part 3312. One end of the first reset member 340 is fitted onto the first limiting part 3312 and abuts against the bottom wall of the mounting hole 3311. The other end of the first reset member 340 is fitted onto the second limiting part 118 and abuts against the cavity wall of the mounting cavity 115 facing the operating port 116. In this way, displacement of the first reset member 340 during deformation can be avoided.

[0197] In one embodiment, as shown in Figures 2 and 4, the bottom surface 112 of the mounting base 110 is further provided with a slot 119 communicating with the mounting cavity 115. A first connector 310 is at least partially movably disposed within the slot 119. One end of the first connector 310 extends into the mounting cavity 115 to connect with the mounting portion 331 of the release member 330, and the other end of the first connector 310 extends towards the opening of the slot 119 to form a hook 311. In this embodiment, the first connector 310 has an elongated structure, and the hook 311 is positioned facing outwards from the base 200. In other embodiments, the hook 311 may also be positioned facing inwards from the base 200.

[0198] In one embodiment, as shown in Figures 11 and 12, the fixing seat 240 is sleeved outside the second connector 320, and the groove 3211 of the second connector 320 (described later) is exposed through the opening 2411 of the fixing seat 240. Specifically, the second connector 320 includes a first connecting portion 321 and a first connecting portion 3220 that are interconnected. Specifically, the first connecting portion 321 is sleeved inside the housing portion 241, and the first connecting portion 321 has the aforementioned groove 3211, which is exposed through the opening 2411 of the housing portion 241. The second connecting portion 322 is provided with an insertion groove 3221, which extends from the end face of the second connecting portion 322 away from the first connecting portion 321 along the length direction of the second connector 320. The housing portion 241 has a first through hole 2412 on the side facing the second cover 220. The second cover 220 has a second through hole 222 opposite to the first through hole 2412. The second connecting portion 322 passes through the first through hole 2412 and the second through hole 222 in sequence to enter the receiving space 102. The first end 2522 of the reinforcing tube 252 (i.e., the end of the reinforcing tube 252 away from the connecting bracket 251) extends upward after passing through the bottom surface 112 of the support member 230 and is inserted into the insertion groove 3221. In some embodiments, the connection between the reinforcing tube 252 and the second connecting member 320 is achieved by fasteners (not shown in the drawings) passing between the second connecting portion 322 and the reinforcing tube 252. This arrangement can improve the installation stability of the second connecting member 320. In some embodiments, the housing portion 241 may also be omitted.

[0199] As shown in Figures 11 and 12, when it is necessary to connect the main body 100 to the base 200, the housing portion 241 of the fixing seat 240 can be inserted into the slot 119 of the mounting seat 110. Simultaneously, pressing the release member 330 causes the first connecting member 310 to move to the unlocked position. The first reset member 340 deforms, and the hook portion 311 of the first connecting member 310 avoids the housing portion 241 of the fixing seat 240 and the first connecting portion 321 of the second connecting member 320, allowing the housing portion 241 to be smoothly inserted into the slot 119. Then, the release member 330 can be released. Under the elastic restoring force of the first reset member 340, the release member 330 resets and moves the first connecting member 310 to the locked position. The hook portion 311 of the first connecting member 310 engages with the slot portion 3211 of the second connecting member 320. This achieves a fixed connection between the body 100 and the base 200. When it is necessary to disassemble the body 100 and the base 200, the release member 330 can be pressed, causing the first connecting member 310 to move to the release position. The first reset member 340 deforms, and the hook 311 of the first connecting member 310 moves out of the groove 3211 of the first connecting member 320. This opening pulls the body 100 upward, causing the fixing seat 240 to move out of the slot 119 of the mounting seat 110, thus separating the body 100 from the base 200.

[0200] In one embodiment, as shown in Figures 1 to 3, a second connecting mechanism 400 may be provided between the body 100 and the base 200. The first connecting mechanism 400 may include a first mating member 410 and a first mating member 420 that can cooperate with each other. The first mating member 410 is disposed at the edge of the body 100, and the first mating member 420 is disposed at the edge of the base 200. In this embodiment, there are two second connecting mechanisms 400, which are respectively disposed at approximately the middle of the two short sides of the body 100 and the base 200. Specifically, the first mating members 410 of the two second connecting mechanisms 400 are respectively located outside the top rods 121 of the two outermost first support rods 120a (specifically, the first mating members 410 are sewn and fixed to the cover 130 sleeved outside the corresponding top rods 121), and the second mating members 420 of the two second connecting mechanisms 400 are respectively disposed at the opposite short side edges of the base 200. Thus, if the body 100 and the base 200 remain connected and not disassembled, when it is necessary to fold the body 100 to facilitate pet access, only at least one of the second connecting mechanisms 400 needs to be released. Even if the first mating part 410 and the second mating part 420 of at least one of the second connecting mechanisms 400 are disengaged, at least a portion of the wooden body 100 can be folded, opening the support device 10 for pet access. When it is necessary to disassemble the body 100 and the base 200, both second connecting mechanisms 400 and both second connecting mechanisms 300 can be released, allowing the body 100 and the base 200 to separate, thus also allowing pet access.

[0201] In this embodiment, the first mating member 410 can be a first magnetic snap, and the second mating member 420 can be a second magnetic snap that can be attracted and mated with the first magnetic snap. Of course, in other embodiments, the first mating member 410 and the second mating member 420 can be, for example, mutually mating snap assemblies or button assemblies, etc., and the present invention does not limit this.

[0202] Of course, in other embodiments, the number and position of the second connecting mechanism 400 can be adjusted as needed. Alternatively, the second connecting mechanism 400 can be omitted, and the body 100 and the base 200 can be detachably connected only through the first connecting mechanism 300.

[0203] Referring to Figure 13, the support device 10 is also provided with a fixing mechanism 40. In this embodiment, the fixing mechanism 40 can be connected to the housing of the support device 10, for example, through a fixed connection or a detachable connection. The support device 10 can be fixed to the car seat 30 through the fixing mechanism 40. More specifically, the fixing mechanism 40 is detachably fixed to the housing of the carrier 10; or, the fixing mechanism 40 may be non-detachably fixed to the housing of the carrier 10, so that a portion of the fixing mechanism 40 is always connected to the housing of the carrier 10, i.e., there is no need to repeatedly install or remove the fixing mechanism 40. In some examples, when the carrier 10 is fixed to the car seat 30, the rear side of the carrier 10 faces the backrest 31 of the car seat 30, the base 200 is supported by the seat 32 of the car seat 30, the fixing mechanism 40 extends from the side of the carrier 10 away from the backrest 31 through the bottom side of the base 200 or through the base 200, and both ends of the fixing mechanism 40 extend toward the backrest 31 and are respectively connected to different positions on the car seat 30, so as to stably and securely fix the carrier 10 to the car seat 30.

[0204] Furthermore, the fixing mechanism 40 has a used state (as shown in Figure 13) and a non-used state (not shown in the figure). When the fixing mechanism 40 is connected to the housing of the support device 10 and the car seat 30, the fixing mechanism 40 is in the used state; otherwise, the fixing mechanism 40 is in the non-used state (not shown in the figure). The fixing mechanism 40 includes a fixing strap 41 and connecting components (not labeled in the figure) disposed on the fixing strap 41. The fixing strap 41 is, for example, a webbing. In this embodiment, there are two fixing straps 41. The connecting components include a first connecting component 42 disposed at the first end of the two fixing straps 41 and two second connecting components (not shown in the figure) respectively disposed at the second end of the two fixing straps 41. The first connecting component 42 includes, for example, a connecting hook 421 that can bypass the top of the body 100 and connect to the backrest 31 of the car or other relevant connection points above the car seat 30. Specifically, referring to Figure 9, the first ends of the two fixing straps 41 pass through the first end 2541a of the guide channel 2541 and exit through the second end 2541b of the guide channel 2541. Since the first ends 2541a of the two guide channels 2541 are close to each other and the second ends 2541b of the two guide channels 2541 are far apart, the distance between the two fixing straps 41 increases as they extend from the first end 2541a to the second end 2541b of the guide channel 2541. The increased distance between the two fixing straps 41 extends upward past the base 200 and wraps around (or covers) the front side of the body 100 and extends from the body 100. After the top handle 150 extends below the body, the connecting hook 421 connects to the connecting component (e.g., connecting crossbar) provided on the backrest 31. The two fixing straps 41 are spaced far apart when bound to the surface of the body 100, increasing the binding range of the body 100 and making the entire support device 10 more securely mounted on the car seat 30. Two second connecting components (not shown) extend towards the backrest 31 of the car and then connect to the connecting components (not shown) on the left and right sides of the seat portion 32 of the car seat 30. As shown in FIG13, after the fixing mechanism 40 is connected to the body 100 of the support device 10 and the car seat 30, at least a portion of the two fixing straps 41 is wrapped around (or covers) the front side of the body 100. In some embodiments, the second connecting components can be ISOFIX connectors, connected to the TSOFIX anchor points of the car.In this embodiment, please refer to Figures 9 and 13 together. When the fixing mechanism 40 is not in use, a portion of the two fixing straps 41 and the second connecting component can be stored in the first storage slot 231, and a portion of the two fixing straps 41 and the second connecting component 42 can be stored in the first receiving slot 232. As shown in Figure 13, when the fixing mechanism 40 needs to be used, the second connecting component and the first connecting component 42 are removed from the first storage slot 231 and the first storage slot 232, respectively.

[0205] Referring to Figures 8 and 14, the carrying mechanism 10 can also be mounted on the trolley 20. The trolley 20 has a mounting plate 21, and a locking mechanism 22 is provided approximately in the middle of the mounting plate 21. The carrying device 10 can be placed on the mounting plate 21. The locking mechanism 22 engages with the locking element 270, thus enabling the pet carrying mechanism to be mounted on the trolley 20. The mounting plate 21 can be raised and lowered relative to the frame, facilitating the folding or unfolding of the trolley, or facilitating the adjustment of the height of the mounting plate 21 to accommodate carrying devices 10 of different heights. First example

[0206] As shown in Figure 15, the first embodiment of the present invention also proposes a supporting device 10, which also includes a body 100, a base 200, and a first connecting mechanism 300. Similar to the first embodiment, the body 100 and the base 200 are detachably connected to form a accommodating space 101 for accommodating pets (see Figure 19). The first connecting mechanism 300 is disposed between the body 100 and the base 200 to achieve a detachable connection between the two. The body 100 and the base 200 are connected to form the box of the supporting device 10. The supporting device in this embodiment is largely the same as the supporting device in the second embodiment, with only some differences in the structure of the body 100 and the base 200. These differences will be described in detail below:

[0207] As shown in Figures 16 to 18, similar to the first embodiment, the height L1 of the accommodating space 101 in this embodiment is not less than half the length L2 of the body 100. For example, the height L1 of the accommodating space 101 can be approximately 430mm to 520mm (i.e., 430mm WL1M 520mm), and the length L2 of the body 100 can be approximately 760mm to 940mm (i.e., 760mm WL2W940mm). In this embodiment, the height L1 of the accommodating space 101 can be 475mm, and the height L2 of the body 100 can be 850mm. In this embodiment, the width L3 of the body 100 is not less than half the length L2 of the body 100, and the width L3 of the body 100 corresponds to the front-to-back dimension of the body 100. For example, the width L3 of the body 100 can be approximately 430mm to 530mm (i.e., 430mmWL3W530mm). In this embodiment, the width L3 of the body 100 can be 485mm.

[0208] As shown in Figures 19 to 21, similar to the first embodiment, the body 100 in this embodiment can also switch between a closed state and an open state. The open state of the body 100 can include a fully open state or a half-open state. The body 100 in this embodiment also includes a mounting base 110, multiple support rods 120, and a cover 130 (see Figure 15). Similar to the first embodiment, the multiple support rods 120 can include a first support rod 120a and a second support rod 120b. In this embodiment, the body 100 can also include two first support rods 120a and two second support rods 120b. Unlike the two first support rods 120a and two second support rods 120b in the first embodiment, in this embodiment, the two ends of the two first support rods 120a are rotatably connected to the two mounting bases 110 respectively, and the two ends of the two second support rods 120b are also rotatably connected to the two mounting bases 110 respectively. In this embodiment, the two second support rods 120b are also arranged adjacent to each other, and the two first support rods 120a are located on both sides of the two second support rods 120b. When the main body 100 is in the closed state as shown in Figure 20 (which can also be called the unfolded state in this embodiment), the height of the highest point of the two first support rods 120b is higher than the height of the highest point of the two first support rods 120a. Specifically, when the main body 100 is in the closed state as shown in Figure 20, the two second support rods 120b are approximately perpendicular to the two first support rods 120a, that is, the two second support rods 120b are basically in a vertical state, and the two first support rods 120a are basically in a horizontal state, which is similar to the situation in the first embodiment. Unlike the first embodiment, as shown in Figure 21, in this embodiment, both the first support rods 120a and the second support rods 120b are rotatably arranged relative to the mounting base 110. The rotation range of the first support rod 120a is greater than 90 degrees. For example, the maximum rotation range of the first support rod 120a can be 100 degrees to 180 degrees, more specifically, the maximum rotation range of the first support rod 120a can be 110 degrees to 135 degrees. In some practical examples, the maximum rotation range of the first support rod 120a is 100 degrees, 110 degrees, 120 degrees, 135 degrees, or 145 degrees, etc. Since the two first support rods 120b can rotate relative to the mounting base 110, the cover 130 connected between the two second support rods 120b can be in an open state when the portions of the two second support rods 120b away from the mounting base 110 are far apart from each other, and can be in a contracted state when the portions of the two second support rods 120b away from the mounting base 110 (see below) are close to each other.In this embodiment, when the main body 100 is in the closed state, the two first support rods 120a can rotate 180 degrees relative to each other, that is, the two first support rods 120a are basically in a horizontal state. Simultaneously, the two first support rods 120a drive the connected cover 130 to unfold, and the cover 130 and the base 200 form an accommodating space 101. When the main body 100 is in the open state, the two first support rods 120a can rotate relative to each other to be relatively parallel, that is, the two first support rods 120a are basically in a vertical state. Simultaneously, the two first support rods 120a drive the connected cover 130 to fold, forming an opening between the cover 130 and the base 200. When the main body 100 is in a semi-open state, the first support rod 120a and the second support rod 120b on one side can rotate relative to the mounting base 110 to form a certain angle with the plane of the base 200, for example, about 100 to 130 degrees, and drive the connected cover 130 to fold, forming an opening between one side of the cover 130 and one side of the base 200. The second support rod 120b on the other side can also rotate relative to the mounting base 110 at a similar angle, while the first support rod 120a on the other side remains in a roughly horizontal state. This allows for a larger rotation angle of the first support rods 120a and 120b on one side relative to the mounting base 110, and a larger opening formed between the one side of the cover 130 and the other side of the base 200, making it easier for pets to enter and exit the carrying device 10.

[0209] In one embodiment, as shown in FIG22, the main body 100 may further be provided with multiple support bars 140 between the first support rod 120a and the second support rod 120b, and the cover 130 is connected to the multiple second support rods 120b, the multiple first support rods 120a and the multiple support bars 140. The number, structure and connection relationship of the support bars 140 in this embodiment are similar to those in the first embodiment, and will not be described again here.

[0210] Please refer to Figures 23 to 25 together. Taking one of the mounting bases 110 as an example, its structure is described in detail. The mounting base 110 is generally a hexagonal flat shell structure. The mounting base 110 includes a top surface 111 and a bottom surface 112 opposite to each other. The mounting base 110 is provided with at least two connecting seats 180. The body 100 includes at least two first pivot seats 191 and at least two second pivot seats 192. At least two first support rods 120a are rotatably connected to their corresponding connecting seats 180 through at least two first pivot seats 191, and at least two first support rods 120b are rotatably connected to their corresponding connecting seats 180 through at least two second pivot seats 192. The mounting base 110 is provided with a clearance groove, and the connecting seats 180 are disposed within the clearance groove. More specifically, in this embodiment, the mounting base 110 has a first clearance groove 113 and a second clearance groove 114, which are located on opposite sides of the mounting base 110. The body 100 also includes two connecting seats 180, which are respectively received in the first clearance groove 113 and the second clearance groove 114. The body 100 also includes two first pivot seats 191, which are pivotally connected to the two connecting seats 180. One of the first support rods 120a is connected to one of the first pivot seats 191, and the other first support rod 120a is connected to the other first pivot seat 191. Thus, one of the first support rods 120a is rotatably connected to one of the connecting seats 180 via one of the first pivot seats 191, i.e., rotatably connected to the mounting seat 110; the other first support rod 120a is rotatably connected to the other connecting seat 180 via the other first pivot seat 191, i.e., rotatably connected to the mounting seat 110. The body 100 also includes two second pivot seats 192, which are pivotally connected to the two connecting seats 180 respectively. Specifically, one first support rod 120b is connected to one of the first pivot seats 192, and the other second support rod 120b is connected to the other second pivot seat 192. Thus, one of the second support rods 120b is rotatably connected to one of the connecting seats 180 via one of the second pivot seats 192, that is, rotatably connected to the mounting seat 110; the other second support rod 120b is rotatably connected to another connecting seat 180 via another second pivot seat 192, that is, rotatably connected to the mounting seat 110.It should be noted that the support bar 140 is positioned relative to the cover 130, and the support bar 140 can move its position as the cover 130 unfolds and retracts. For example, the cover 130 has multiple channels (not shown), and multiple support bars 140 are respectively inserted into one of the corresponding channels.

[0211] In some embodiments, the mounting base 110 may not have a clearance groove, and the connecting base 180 may be directly connected to the edge of the mounting base 110 without being accommodated in the clearance groove; this is not limited here. In other embodiments, there may be only one or more connecting bases 180. For example, the mounting base 110 may have only one first support rod 120a and one second support rod 120b, and the first support rod 120a and the second support rod 120b may be connected to the same connecting base 180. For example, a first pivot base 191 may extend two or more components simultaneously for connecting several first support rods 120a and / or several second support rods 120b; in this case, the number of connecting bases 180 can be adjusted accordingly.

[0212] The following description uses the connecting seat 180, the first pivot seat 191, and the second pivot seat 192 located on one side of the mounting seat 110 as examples to illustrate their structure and connection relationship:

[0213] In this embodiment, the first support rod 120a is rotatable relative to the mounting base 110, and the first support rod 120a can be positioned at multiple positioning angles relative to the mounting base 110. That is, when no external force is applied (e.g., when the user does not rotate the first support rod 120a relative to the mounting base 110), the first support rod 120a can be positioned relative to the mounting base 110 at any of the multiple positioning angles. For example, after rotation, the first support rod 120a is positioned at a 45-degree angle relative to the horizontal plane. Specifically, the positioning between the first support rod 120a and the mounting base 110 is achieved through the cooperation between the connecting seat 180 and the first pivot seat 191. More specifically, as shown in Figures 23 and 24, the connecting seat 180 has a first mating portion 1841, and the first pivot seat 191 has a second mating portion 1911a. The second mating portion 1911a and the first mating portion 1841 are mutually restrictive to limit the rotation of the first pivot seat 191 relative to the connecting seat 180. The first pivot seat 191 can be operated to overcome the restrictive effect of the second mating portion 1911a and the first mating portion 1841 to allow the first pivot seat 191 to rotate relative to the connecting seat 180. The second pivot seat 192 is adapted to abut against the groove wall of the clearance groove to limit the rotation angle range of the second pivot seat 192. Specifically, as shown in Figures 23 and 24, the connecting seat 180 is generally cylindrical, and the axial direction of the connecting seat 180 extends generally along the front-rear direction of the bearing device 10. The connecting seat 180 includes an outer connecting cylinder 181 and an inner connecting cylinder 182. At least a portion of the outer side wall of the outer connecting cylinder 181 is connected to the groove wall of the first clearance groove 113. The inner connecting cylinder 182 is located inside the outer connecting cylinder 181 and is concentrically arranged with the outer connecting cylinder 181. The axial length of the inner connecting cylinder 182 is greater than the axial length of the outer connecting cylinder 181, and the two ends of the inner connecting cylinder 182 axially protrude from the two ends of the shaft of the outer connecting cylinder 181, respectively. The central hole of the inner connecting cylinder 182 forms a first pivot hole 1820. The connecting seat 180 may also include a first connecting rib 183. There are multiple first connecting ribs 183, which are connected between the outer connecting cylinder 181 and the inner connecting cylinder 182. The connecting seat 180 may also include a mating cylinder 184, which is located on one side of the outer connecting cylinder 181 axially. Specifically, the mating cylinder 184 is also a cylindrical structure, and its outer peripheral wall is connected to the inner peripheral wall of the outer connecting cylinder 181. A first mating portion 1841 is provided at one end of the mating cylinder 184 that protrudes from the outer connecting cylinder 181. In this embodiment, the first mating portion 1841 includes a plurality of circumferentially spaced toothed protrusions 1841a.In some embodiments, the first connecting rib 183 and the outer connecting cylinder 181 can be selectively omitted. In some embodiments, the connecting seat 180 is not limited to a cylindrical structure; for example, it can be a cylindrical structure or a square block structure, and the first mating part 1841 can be disposed on the side of the connecting seat 180 facing the first pivot seat 191. In some embodiments, the mating cylinder 184 can also be omitted; for example, the first mating part 1841 can be disposed on the end of the outer connecting cylinder 181 facing the first pivot seat 191.

[0214] As shown in Figures 24 and 25, the first pivot seat 191 includes a first pivot portion 1911 and a first joint portion 1912 that are connected to each other. In this embodiment, the first pivot seat 191 is an integrally formed structure. In other embodiments, the first pivot seat 191 may also be formed by connecting the separate first pivot portion 1911 and the first joint portion 1912 by means of welding, splicing, etc. The first pivot portion 1911 is generally a disc-shaped structure, and a second pivot hole 1910 is formed at approximately the center of the first pivot portion 1911. A second mating portion 1911a is provided on one of the middle surfaces of the first pivot portion 1911. The second mating portion 1911a includes a plurality of toothed protrusions 1911b, which are circumferentially spaced around the second pivot hole 1910. The first pivot portion 1911 is pivotally connected to the connecting seat 180. The second mating portion 191a and the first mating portion 1841 cooperate with each other to restrict the first pivot seat 191 relative to the mounting seat 110 at a specific angle. The first joint portion 1912 is generally a rectangular cylindrical structure. One end of the first joint portion 1912 is connected to the first pivot portion 1911, and the other end of the first joint portion 1912 has a first insertion groove 1912a. The first end of the first support rod 120a is inserted into the first insertion groove 1912a. In some embodiments, the second joint portion 1912 can also be omitted, that is, the first pivot seat 191 can only include the first pivot portion 1911, and the first support rod 120a can be directly connected to the first pivot portion 1911.

[0215] As shown in Figures 23 and 24, the second pivot seat 192 includes a second pivot portion 1921 and a second joint portion 1922 that are interconnected. In this embodiment, the second pivot seat 192 is an integrally formed structure. In other embodiments, the second pivot seat 192 may also be formed by connecting the separate second pivot portion 1921 and the second joint portion 1922 through welding, keying, or other methods. The second pivot portion 1921 includes an outer pivot cylinder 1921a and an inner pivot cylinder 1921b. The outer pivot cylinder 1921a is connected to the second joint portion 1922, and the inner pivot cylinder 1921b is located inside the outer pivot cylinder 1921a and is concentrically arranged with the outer pivot cylinder 1921a. One axial end of the inner pivot cylinder 1921b protrudes into one end of the outer pivot cylinder 1921a. The central hole of the inner pivot cylinder 1921b forms a third pivot hole 1920. The second pivot seat 192 may further include a second connecting rib 1923. Multiple second connecting ribs 1923 are present and connected between the outer pivot cylinder 1921a and the inner pivot cylinder 1921b. The first pivot portion 1911 is pivotally connected to the connecting seat 180. The second joint portion 1922 is generally a rectangular cylindrical structure; one end of the second joint portion 1922 is connected to the second pivot portion 1921, and the other end of the first joint portion 1922 has a first insertion groove 1922a. One end of the first support rod 120b is inserted into the first insertion groove 1922a. In some embodiments, the first connecting rib 1923 may be omitted. In some embodiments, the first pivot portion 1921 may not include the outer pivot cylinder 1921a and the inner pivot cylinder 1921b. Instead, the second pivot portion 1921 may be integrally cylindrical (or square columnar or polygonal columnar) in shape, and a third pivot hole 1920 may be formed approximately in the middle of the second pivot portion 1921. In some embodiments, the second connecting portion 1922 may also be omitted, that is, the second pivot seat 192 may only include the second pivot portion 1921, and the second support rod 120b may be directly connected to the second pivot portion 1921.

[0216] In one embodiment, as shown in FIG23, the body 100 may further include a pivot member 193. The pivot member 193 passes through the first pivot seat 191, the second pivot seat 192, and the connecting seat 180 to achieve pivoting between the two. Specifically, the pivot member 193 passes through the second pivot portion 1921, the connecting seat 180, and the first pivot portion 1911 to achieve pivoting between the first pivot seat 191, the second pivot seat 192, and the connecting seat 180. More specifically, the first pivot seat 191 is pivotally connected to the outside of the connecting seat 180, that is, the side of the connecting seat 180 facing away from the receiving space 101, and the second pivot seat 192 is pivotally connected to the inside of the connecting seat 180, that is, the side of the connecting seat 180 facing the receiving space 101. The inner connecting cylinder 182 of the connecting seat 180 is inserted into the second pivot hole 1910 of the first pivot part 1911, and the inner pivot cylinder 1921b of the second pivot part 1921 is inserted into the first pivot hole 1820 of the connecting seat 180. The pivot member 193 passes through the second pivot part 1921, the connecting seat 180 and the first pivot part 1911, or in other words, the pivot member 193 passes through the third pivot hole 1920, the third pivot hole 1820 and the second pivot hole 1910 to realize the separate pivot connection between the first pivot seat 191, the second pivot seat 192 and the connecting seat 180.

[0217] Of course, in other embodiments, the positions of the first pivot seat 191 and the second pivot seat 192 can also be reversed, that is, the second pivot seat 192 is pivotally connected to the outside of the connecting seat 180, that is, the side of the connecting seat 180 facing away from the accommodating space 101, and the first pivot seat 191 is pivotally connected to the inside of the connecting seat 180, that is, the side of the connecting seat 180 facing the accommodating space 101. As mentioned above, the first pivot seat 191, through the mating of the first fitting portion 1911a and the first mating portion 1841, can restrict the first pivot seat 191 relative to the mounting seat 110 at a certain positioning angle. When it is necessary to adjust the tilt angle of the first support rod 120a to open or close the main body 100, as shown in Figure 22, a certain external force can be applied to the first support rod 120a, so that the toothed protrusion 1911b of the second mating part 1911a overcomes the limitation formed by the toothed protrusion 1841a of the first mating part 1841 (or it can be said that the second mating part 1911a and the first mating part 1841 push against each other and undergo a certain degree of relative movement), thereby allowing the first pivot seat 191 to rotate relative to the connecting seat 180 (or mounting seat 110). The rotation of the first support rod 120a can drive the cover 130 to fold or unfold, and drive the first support rod 120b to rotate through the pushing force of the first support rod 120a and / or the cover 130. Please also refer to Figure 23. The connection between the first joint 1922 or the second joint 1922 and the second pivot 1921 of the first pivot seat 192 can abut against one or both sides of the groove wall of the first clearance groove 113 or the second clearance groove 114, thereby limiting the maximum rotation angle range of the second support rod 120b.

[0218] It should be noted that in some embodiments, the first mating part 1841 and the second mating part 1911a can be in other forms and are not limited to the toothed protrusions of this embodiment. For example, the first mating part 1841 is a positioning protrusion, and the first mating part 1911a is a plurality of spaced positioning fours. The positioning protrusion and the positioning concave shape cooperate with each other. When the positioning protrusion selectively engages with one of the plurality of positioning fours, the first pivot seat 191 is positioned with the mounting seat 110.

[0219] In some embodiments, when the first pivot seat 191 needs to rotate relative to the mounting base 110, the first support rod 120a is subjected to an external force. The toothed protrusions 1911b of the second mating portion 1911a and the toothed protrusions 1841a of the first mating portion 1841 can be briefly deformed by their own material elasticity, thereby realizing the relative rotation of the first pivot seat 191 and the mounting base 110. In some embodiments, the mounting base 110 may also be provided with an elastic element (not shown in the figure), which makes the first pivot seat 191 tend to move in a constant direction toward the mounting base 110. For example, the elastic element is a spring, which provides a constant force to the first pivot seat 191 toward the connecting base 180, so that the toothed protrusions 1911b of the second mating portion 1911a and the toothed protrusions 1841a of the first mating portion 1841 come closer to each other for engagement and limiting, and the first pivot seat 191 and the connecting base 180 can be locked and positioned together. When the first pivot seat 191 needs to rotate relative to the mounting base 110, it is subjected to an external force that overcomes the force of the elastic element. The elastic element deforms, allowing the first pivot seat 191 to move away from the connecting base 180. The toothed protrusions 1911b of the second mating part 1911a and the toothed protrusions 1841a of the first mating part 1841 move away from each other, allowing the first pivot seat 191 to rotate relative to the mounting base 110. The first pivot seat 191 can then rotate to another position. For example, the elastic element can be located between the connecting base 180 and the first pivot seat 191. This elastic element is a tension spring that can pull the first pivot seat 191 towards the connecting base 180. For example, the first pivot 191 has a receiving groove on the side opposite to the connecting seat 180. The first pivot 191 has a cover positioned in the opening of the receiving groove, and an elastic member is received in the receiving groove. One end of the elastic member abuts against the groove wall of the receiving groove of the first pivot 191, and the other end of the elastic member abuts against the cover. The elastic member can be a compression spring, which can apply elastic pressure to the first pivot 191 toward the connecting seat 180.

[0220] Referring to Figures 17, 20, and 21, the first pivot 192 can rotate between a first position and a second position (or the second support rod 120b can rotate between a first position and a second position). When the body 100 is in the closed state (as shown in Figure 20), the second pivot 192 is in the first position. When the body 100 is in the open state, the second pivot 192 is in the second position. As shown in Figure 21, the body 100 is in a semi-open state, with the right side of the body 100 operated open, and both the first support rod 120a and the second support rod 120b on the right side rotating to the left to open, but the left side of the body 100 remains closed. Specifically, in this embodiment, when the body 100 is in the closed state, the second pivot 192 (or the second support rod 120b) is in a generally vertical state. The second pivot 192 does not abut against the wall of the clearance groove, but due to the restriction of the cover 130, the rotation of the first pivot 192 is restricted, and the first pivot 192 remains in the first position. In this embodiment, when the body 100 is in a semi-open state, the second pivot 192 of the body 100 located on the open side is in the second position. Specifically, when the second pivot 192 rotates to the second position, the second pivot 192 will abut against the wall of the clearance groove, so that the second pivot 192 can no longer continue to rotate, thereby restricting the rotation angle of the second pivot 192. The second pivot 192 also has a third position (or the second support rod 120b also has a third position). In this embodiment, the third position is between the first position and the third position. Referring to Figure 21, when the first support rod 120b on one side of the main body 100 (e.g., the second support rod 120b on the right side of Figure 21) rotates to the second position, the first support rod 120b on the other side (e.g., the second support rod 120b on the left side of Figure 21) rotates to the third position. Specifically, when the main body 100 is in a semi-open state, the second support rod 120b on the other side (e.g., the second support rod 120b on the left side of Figure 21) may rotate to the third position due to the pushing force generated by the closing of the cover 130 or due to the user's flicking operation. However, due to the restriction of the cover 130, the second support rod 120b on the other side (e.g., the second support rod 120b on the left side of Figure 21) cannot continue to rotate after rotating to the third position, thus remaining in the third position.

[0221] Of course, in other embodiments, the first and second positions of the second support rod 120b can also be other orientations. For example, when the second support rod 120b is in the first position, it is approximately vertical; when the second support rod 120b is in the second position, it is approximately horizontal or at an angle of 135 degrees to the horizontal plane. The first and second positions are not limited to the specific positions provided in the accompanying drawings of this embodiment. In other embodiments, the second pivot seat 192 can also be maintained in the first or second position by abutting against the groove wall of the avoidance groove.

[0222] As shown in Figures 25 and 26, similar to the first embodiment, the base 200 includes a housing, which has a first cover 210 and a second cover 220. The structure of the first cover 210 in this embodiment is substantially the same as that in the first embodiment. The structure of the second cover 220 in this embodiment is also substantially the same as that in the first embodiment, with only some structural differences, which will be detailed below:

[0223] In one embodiment, as shown in Figure 17, the base 200 also includes a support member 230. The support member 230 in this embodiment has the same structure as the support member 230 in the first embodiment, and will not be described again here. As shown in Figures 17 and 25, a mat 201 can also be laid on the support member 230 to provide cushioning protection for the pet riding on it and to improve the pet's riding comfort.

[0224] In one embodiment, as shown in FIG25, the base 200 may further include a fixing seat 240. The structure of the fixing seat 240 in this embodiment is the same as that in the first embodiment, and will not be described again here. The upper part of the housing has an upwardly protruding limiting ridge 221. Specifically, the second cover 220 is provided with an upwardly protruding limiting ridge 221. In this embodiment, there are two limiting ridges 221, both of which are U-shaped ridges. One limiting ridge 221 is located on the left side of the two fixing seats 240, and the other limiting ridge 221 is located on the right side of the two fixing seats 240. Each limiting protrusion 221 near the ends of the two fixing seats 240 forms a relief slope 2211 to adapt to the / ', lateral shell structure of the mounting seat 110 of the body 100. For example, the relief slope 2211 is adapted to the two inclined extending side surfaces 160 of the mounting seat 110 connected to the bottom surface 112 on both sides of the mounting seat 110.

[0225] Referring to Figures 22 and 25, each limiting protrusion 221 has a first end and a second end. The first ends of the two limiting protrusions 221 are arranged opposite each other, and the second ends of the two limiting protrusions 221 are arranged opposite each other. In this embodiment, the two first ends of the two limiting protrusions 221 are located on both sides of one of the fixing seats 240. Unlike the first embodiment, the portions of the two first ends are spaced apart to form a first gap region 204. At least a portion of the fixing seat 240 can enter the first gap region 204. For example, portions of the two first ends are spaced apart and respectively form the aforementioned clearance ramps 2211. In this embodiment, the other portions of the two first ends of the two limiting protrusions 221 can be connected, for example, by a first connecting structure 202. The first connecting structure 202 is close to the receiving space 101 relative to the first gap region 204. The first connecting structure 202 is located on the side of the fixing seat 240 facing the receiving space 101. Similarly, the two second ends of the two limiting protrusions 221 are located on both sides of another fixing seat 240. A portion of the two second ends is spaced apart to form a second gap region 205. At least a portion of the fixing seat 240 can enter the second gap region 205. For example, a portion of the two first ends is spaced apart and respectively forms the aforementioned clearance ramps 2211. In this embodiment, the other portions of the two second ends of the two limiting protrusions 221 can be connected, for example, by a second connecting structure 203. The second connecting structure 203 is close to the receiving space 101 relative to the second gap region 205. The first connecting structure 203 is located on the side of the fixing seat 240 facing the receiving space 101. Thus, the inner sides of the two limiting protrusions 221, the inner sides of the first connecting structure 202, and the inner sides of the second connecting structure 203 connect to form a completely closed annular enclosure 2214. When the main body 100 is removed, the annular enclosure 2214 can provide a certain degree of protection for the pet located on the base 200, and at the same time, it can also provide a positioning function for the main body 100 when it is installed on the base 200. It should be noted that the first interval region 204 may not be provided between the two first ends of the two limiting protrusions 221; and / or, the second interval region 205 may not be provided between the two second ends of the two limiting protrusions 221.

[0226] In one embodiment, as shown in Figures 27 and 28, the base 200 further includes a tubular structure 250. The tubular structure 250 in this embodiment differs somewhat from that in the first embodiment. A receiving space 102 is formed between the support member 230 and the housing to accommodate the tubular structure 250. More specifically, the receiving space 102 is formed between the support member 230 and the first cover 210. In some embodiments, the tubular structure 250 is located at the bottom of the support member 230. In some embodiments, the tubular structure 250 may also be embedded inside the support member 230 or located above the support member 230, without limitation. The tubular structure 250 in this embodiment does not include a connecting frame 251. The tubular structure 250 includes a reinforcing tube 252. The reinforcing tube 252 extends generally along a direction parallel to the short side of the support member 230, or in other words, at least a portion of the reinforcing tube 252 extends in a front-rear direction. The reinforcing tube 252 is recessed approximately in the middle towards the support member 230. Both ends of the reinforcing tube 252 extend upwards to connect with the second connecting members 320 of the two first connecting mechanisms 300. The tubular structure 250 also includes a connecting tube 253. The connecting tube 253 extends approximately parallel to the long side of the support member 230, or at least a portion of the connecting tube 253 extends in a left-right direction. The connecting tube 253 is recessed approximately in the middle towards the support member 230. Thus, the reinforcing tube 252 and the connecting tube 253 reinforce the base 200 longitudinally and laterally, respectively, improving the support strength of the base 200.

[0227] In one embodiment, as shown in Figures 26 and 27, the base 200 may further include a supporting protrusion 255. The number, structure, and connection relationship of the supporting protrusion 255 in this embodiment are largely the same as those in the first embodiment, and will not be described again here.

[0228] In one embodiment, as shown in Figures 27 and 28, the base 200 further includes guide blocks 254. The number, structure, and connection relationship of the guide blocks 254 in this embodiment are largely the same as those in the first embodiment, and will not be described again here.

[0229] In one embodiment, as shown in Figures 26 and 27, the support member 230 may further be provided with a first storage groove 231 and a second storage groove 232. The first cover 210 is provided with an openable first storage cover 212 and a second storage cover 213 at corresponding positions, opposite to the first storage groove 231 and the second storage groove 232. The first storage groove 231, the second storage groove 232, the first storage cover 212, and the first storage cover 213 in this embodiment are the same as those in the first embodiment, and will not be described again here.

[0230] In one embodiment, the base 200 may further include a mating seat 260 and a locking member 270 for connection with the trolley 20 (not shown in the figures of this embodiment). As shown in Figures 26 to 28, the approximately central portion of the reinforcing tube 252 and the approximately central portion of the connecting tube 253 are recessed towards the support member 230, thereby forming an installation space 280 for accommodating the mating seat 260. The housing (e.g., the first cover 210) has an installation opening (not shown) corresponding to the position of the installation space 280. The mating seat 260 is installed in the installation space 280 through the installation opening. The mating seat 260 is generally square block-shaped. The mating seat 260 has a groove 261. In some embodiments, the groove 261 may be square, circular, or other shapes, and the groove 261 may be located in the center of the mating seat 260 or other positions. The locking member 270 is disposed within the groove 261. In this embodiment, the engaging member 270 has a rod-like structure, with its two ends connected to the two side walls of the groove 261, respectively. Specifically, the engaging member 270 may include a U-shaped rod 271 located in the middle and straight rods 272 connected to the two ends of the U-shaped rod 271. The U-shaped rod 271 protrudes away from the bottom of the groove 261. The opposite side walls of the groove 261 are respectively provided with through holes 262. The two straight rods 272 pass through the two through holes 262 and are fixed to the mating seat 260 by fasteners. In other embodiments, the engaging member 270 may also be a hook-like structure, a protruding post, a groove 261, or other structures, as long as it can be connected to the trolley 20. In other embodiments, the mating seat 260 may not have a groove 261. For example, the bottom surface of the mating seat 260 may be flat, and the U-shaped rod 271 of the engaging member 270 may protrude a greater distance away from the bottom surface of the mating seat 260. In this case, sufficient connection space can still be provided for the connection between the engaging member 270 and the trolley 20.

[0231] It is worth noting that in the first embodiment, the engaging mechanism 22 on the trolley 20 is roughly square-pyramidal, and therefore the groove 261 of the mating seat 260 is also a corresponding square-pyramidal groove. In this embodiment, the engaging mechanism 22 on the trolley 20 is roughly flat and square, and therefore the groove 261 of the mating seat 260 is also a corresponding flat and square groove. In other embodiments, the shapes of the engaging mechanism 22 and the groove 261 can also be adjusted as needed, as long as they can be matched with each other. In a practical example, as shown in Figures 26 to 28, the base 200 also includes support protrusions 290. In this embodiment, there are four support protrusions 290, which are respectively located on the bottom surface 112 of the support member 230. The reinforcing tube 252 and the connecting tube 253 intersect each other, thereby dividing the bottom surface 112 of the support member 230 into four regions, and the four support protrusions 290 are respectively located in these four regions. The four support protrusions 290 are symmetrically arranged relative to the reinforcing tube 252 and the connecting tube 253. In this embodiment, two support protrusions 290 are located between one support protrusion pad 255 and the mating seat 260, or between one guide block 254 and the mating seat 260. The other two support protrusions 290 are located between another support protrusion pad 255 and the mating seat 260, or between another guide block 254 and the mating seat 260. The first cover 210 is correspondingly provided with four connecting ports 214, through which the four support protrusions 290 are exposed. When the supporting device 10 is placed on the mounting plate 21 of the trolley 20 or on the ground or other flat surfaces, the support protrusions 290 can contact the surface to provide better support for the supporting device 10. In other embodiments, the number and location of the support protrusions 290 can be adjusted as needed. For example, the support protrusions 290 can also be connected to the bottom of the reinforcing tube 252 or the connecting tube 253.

[0232] In one embodiment, as shown in Figure 26, the base 200 may also be provided with a grip portion 215. The grip portion 215 allows the user to easily hold the base 200 with both hands when lifting it, making the transport of the base 200 more convenient and smooth. In this embodiment, the grip portion 215 has four points, located at the four corners of the base 200. Of course, in other embodiments, the position of the grip portion 215 can be adjusted as needed. For example, two grip portions 215 can be provided, and these two grip portions 215 are located on opposite sides of the base 200. In this embodiment, the grip portion 215 is located at the bottom of the base 200, and the grip portion 215 is in the shape of a groove. In other embodiments, the grip portion 215 may also be provided at other locations on the base 200, such as on the side of the base; in addition, the grip portion 215 may also be in the form of a rod, a block or other structure, and the number of grip portions 215 may be two, three, six or other, and there is no limitation here.

[0233] In this embodiment, as shown in FIG15, a second connecting mechanism 400 may be provided between the body 100 and the base 200. The second connecting mechanism 400 in this embodiment is substantially the same as the second connecting mechanism 400 in the first embodiment, and will not be described again here.

[0234] In one embodiment, as shown in FIG29, the supporting device 10 is further provided with a fixing mechanism 40. The fixing mechanism 40 in this embodiment is substantially the same as the fixing mechanism 40 in the first embodiment, and will not be described again here.

[0235] Third Embodiment

[0236] As shown in Figure 30, the third embodiment of the present invention also proposes a carrying device 10, which also includes a body 100, a base 200, and a first connecting mechanism 300. Similar to the second embodiment, the body 100 and the base 200 are detachably connected to form a accommodating space 101 for accommodating a pet. The first connecting mechanism 300 is disposed between the body 100 and the base 200 to realize the detachable connection between the two. The body 100 and the base 200 are connected to form the housing of the carrying device 10. The carrying device 10 in this embodiment is generally the same as the carrying device 10 in the second embodiment, with only some differences in the detailed structure of the body 100, the base 200, and the first connecting mechanism 300. These differences will be described in detail below: As shown in Figures 31 to 33, similar to the first embodiment, the body 100 in this embodiment can also switch between a closed state and an open state. The open state of the body 100 may include a fully open state or a half-open state. The body 100 in this embodiment also includes a mounting base 110, multiple support rods 120, and a cover 130 (not shown in the accompanying drawings of this embodiment; see Figure 15 of the second embodiment). Similar to the second embodiment, the multiple support rods 120 may include first support rods 120a and second support rods 120b. In this embodiment, the body 100 may also include two first support rods 120a and two first support rods 120b. Similar to the first embodiment, the two ends of the two first support rods 120a are rotatably connected to the two mounting bases 110, and the two ends of the two first support rods 120b are also rotatably connected to the two mounting bases 110. In this embodiment, the two second support rods 120b are also arranged adjacent to each other, with the two first support rods 120a located on either side of the two second support rods 120b. When the main body 100 is in the closed state as shown in Figure 30 (which can also be referred to as the unfolded state in this embodiment), the height of the highest point of the two second support rods 120b is higher than the height of the highest point of the two first support rods 120a. Specifically, when the main body 100 is in the closed state as shown in Figure 30, the two second support rods 120b are approximately perpendicular to the two first support rods 120a, that is, the two second support rods 120b are basically in a vertical state, and the two first support rods 120a are basically in a horizontal state. As shown in Figure 31, in this embodiment, both the first support rods 120a and the second support rods 120b are rotatably configured relative to the mounting base 110. The rotation range of the first support rod 120a is greater than 90 degrees.For example, the maximum rotation range of the first support rod 120a can be 100 degrees to 180 degrees. More specifically, the maximum rotation range of the first support rod 120a can be 110 degrees to 135 degrees, that is, the first support rod 120a can rotate from a generally horizontal direction to a position forming an angle of 110 degrees to 135 degrees with the horizontal direction. In some embodiments, the maximum rotation range of the first support rod 120a is 100 degrees, 110 degrees, 120 degrees, 135 degrees, or 145 degrees, etc. Since the two second support rods 120b can rotate relative to the mounting base 110, when the cover 130 connecting the two second support rods 120b is in the open state, the portions of the two second support rods 120b away from the mounting base 110 are pulled away from each other by the cover 130. When the cover 130 is in the contracted state, the portions of the two second support rods 120b away from the mounting base 110 (see the following text) can move closer to each other. In this embodiment, when the main body 100 is in the closed state, the two first support rods 120a can rotate in a direction away from each other, so that the two first support rods 120a are basically in a horizontal state, and the two first support rods 120a respectively drive the cover 130 connected to them to unfold, and the cover 130 and the base 200 form an accommodating space 101o. When the main body 100 is in the open state, the two first support rods 120a can rotate in a direction closer to each other, so that the two first support rods 120a are basically in a vertical state, and the two first support rods 120a respectively drive the cover 130 connected to them to fold, forming two openings of about 90 degrees on the left and right sides (or one side opening is 135 degrees and the other side opening is 45 degrees) between the cover 130 and the base 200. When the main body 100 is in a semi-open state, the first support rod 120a and the second support rod 120b on one side can rotate relative to the mounting base 110 to form a certain angle with the plane of the base 200, for example, about 100 to 130 degrees, and drive the connected cover 130 to fold, forming an opening between one side of the cover 130 and one side of the base 200. The second support rod 120b on the other side can also rotate relative to the mounting base 110 at a similar angle, while the first support rod 120a on the other side remains in a roughly horizontal state. This allows for a larger rotation angle of the first support rods 120a and 120b on one side relative to the mounting base 110, and a larger opening between one side of the cover 130 and one side of the base 200, making it easier for pets to enter and exit the carrying device 100.

[0237] In one embodiment, as shown in Figures 30 and 31, the wooden body 100 may also be provided with a plurality of support bars 140 between the first support rod 120a and the second support rod 120b. The cover 130 is connected to the plurality of second support rods 120b, the plurality of first support rods 120a, and the plurality of support bars 140. The number, structure, and connection relationship of the support bars 140 in this embodiment are similar to those in the first embodiment, and will not be described again here.

[0238] In one embodiment, the mounting base 110 in this embodiment differs slightly in structure from the mounting base 110 in the second embodiment. The structure of one mounting base 110 is described in detail below as an example. Referring to Figures 32 to 34, the mounting base 110 in this embodiment has a flat shell structure. The mounting base 110 is provided with at least four connecting seats 180. The body 100 includes at least two first pivot seats 191 and at least two second pivot seats 192. The at least two first pivot seats 191 correspond to at least two of the at least four connecting seats 180, and the at least two second pivot seats 192 correspond to the other connecting seats 180. At least two first support rods 120a are rotatably connected to their corresponding connecting seats 180 via at least two first pivot seats 191, and at least two second support rods 120b are rotatably connected to their corresponding connecting seats 180 via at least two first pivot seats 192. In this embodiment, each side of the mounting base 110 is provided with four connecting seats 180. Two connecting seats 180 are spaced apart on both sides of the mounting base 110 in the left-right direction, and these two connecting seats 180 are referred to as first connecting seats 180a; the other two connecting seats 180 are respectively provided at the top of the mounting base 110 in the up-down direction, and these two connecting seats 180 are referred to as second connecting seats 180b. The plurality of first connecting seats 180a and second connecting seats 180b of the mounting base 110 on each side are substantially on the same vertical plane, and there is a gap between each first connecting seat 180a and each second connecting seat 180b, that is, the second support rod 120b and the first support rod 120a rotate substantially on the same vertical plane, and the rotation axes of the second support rod 120b and the first support rod 120a are offset from each other, thereby reducing wrinkles of the cover 130 on the vertical plane, and reducing interference with the first support rod 120a during the rotation of the second support rod 120b in the direction of unfolding of the body 100, and increasing the rotation angle in the half-open state (for example, in this embodiment, the second support rod 120b can rotate to 135 degrees, which is much greater than 90 degrees). Optionally, the second connecting seat 180b protrudes upward relative to the top of the mounting seat 110, so that the horizontal position of the first connecting seat 180b is higher than the horizontal position of the first connecting seat 180a. Optionally, the first support rod 120a may be arc-shaped, and the first support rod 120a has a curved portion that bends toward the side adjacent to the first support rod 120b, so that when the body 100 is in a semi-open state, the rotation angle of the first support rod 120a is larger, thereby making the opening formed between the body 100 and one side of the base 200 larger.

[0239] Specifically, as shown in Figures 34 and 35, the mounting base 110 is provided with a clearance groove, and the connecting seat 180 is disposed within the clearance groove. More specifically, in this embodiment, the mounting base 110 has two first clearance grooves 113 and two second clearance grooves 114. The two first clearance grooves 113 are respectively located on both sides of the mounting base 110, and the two second clearance grooves 114 are respectively located on the top of the mounting base 110. The two first connecting seats 180a are received in the two first clearance grooves 113, and the two first connecting seats 180b are received in the two first clearance grooves 114. Correspondingly, the body 100 includes two first pivot seats 191 and two second pivot seats 192. The two first pivot seats 191 are pivotally connected to the two first connecting seats 180a. One first support rod 120a is connected to one first pivot seat 191, and the other first support rod 120a is connected to the other first pivot seat 191. Thus, one first support rod 120a is rotatably connected to one first connecting seat 180a via one first pivot seat 191, i.e., rotatably connected to the mounting base 110; the other first support rod 120a is rotatably connected to the other first connecting seat 180a via the other first pivot seat 191, i.e., rotatably connected to the mounting base 110. Two second pivot seats 192 are pivotally connected to two second connecting seats 180b respectively. One of the second support rods 120b is connected to one of the second pivot seats 192, and the other second support rod 120b is connected to another second pivot seat 192. Thus, one of the second support rods 120b is rotatably connected to one of the second connecting seats 180b via one of the second pivot seats 192, i.e., rotatably connected to the mounting base 110; the other first support rod 120b is rotatably connected to another second connecting seat 180b via another first pivot seat 192, i.e., rotatably connected to the mounting base 110. It should be noted that the support bar 140 is positioned relative to the cover 130, and the support bar 140 can move its position as the cover 130 unfolds and retracts. For example, the cover 130 has multiple channels (not shown), and multiple support bars 140 are respectively inserted into one of the corresponding channels.

[0240] In some embodiments, the mounting base 110 may not have a clearance groove, and the connecting base 180 may be directly connected to the edge of the mounting base 110 without being accommodated in the clearance groove; this is not limited here. For example, a first pivot base 191 may extend out two or more components for connection to several first support rods 120a and / or several second support rods 120b; in this case, the number of connecting bases 180 can be adjusted accordingly. Furthermore, there may be only one first connecting base 180a and two second connecting bases 180b, or more than two. For example, the mounting base 110 may have only one first support rod 120a and one second support rod 120b, and the first support rod 120a and the first support rod 120b can be connected to the first connecting base 180a and the second connecting base 180b, respectively.

[0241] In some embodiments, the mounting base 110 may not have a clearance groove, and the connecting base 180 may be directly connected to the edge of the mounting base 110 without being accommodated in the clearance groove; this is not limited here. In other embodiments, there may be only one or more connecting bases 180. For example, the mounting base 110 may have only one first support rod 120a and one second support rod 120b, and the first support rod 120a and the first support rod 120b may be connected to the same connecting base 180. Alternatively, a first pivot base 191 may extend two or more components simultaneously for connection of several first support rods 120a and / or several second support rods 120b; in this case, the number of connecting bases 180 can be adjusted accordingly.

[0242] The following describes the structure and connection relationship of the first connecting seat 180a, the second connecting seat 180b, the first pivot connecting seat 191, and the second pivot connecting seat 192 located on the side where the mounting head 110 is installed, in detail:

[0243] Similar to the second embodiment, the first support rod 120a is rotatable relative to the mounting base 110, and the first support rod 120a can be positioned at multiple positioning angles relative to the mounting base 110. That is, when no external force is applied (e.g., the user does not rotate the first support rod 120a relative to the mounting base 110), the first support rod 120a can be positioned relative to the mounting base 110 at any of the multiple positioning angles. For example, after rotation, the first support rod 120a can be positioned at a 45-degree angle relative to the horizontal plane. Specifically, the positioning between the first support rod 120a and the mounting base 110 is achieved through the cooperation between the first connecting seat 180a and the first pivot seat 191. More specifically, as shown in Figures 34 and 35, the first connecting seat 180a has a first mating portion 1841, and the second pivot seat 191 has a first mating portion 1911a. The first mating portion 1911a and the first mating portion 1841 are mutually restrictive to limit the rotation of the first pivot seat 191 relative to the first connecting seat 180a. The first pivot seat 191 can be operated to overcome the restrictive effect of the second mating portion 1911a and the first mating portion 1841 to allow the first pivot seat 191 to rotate relative to the first connecting seat 180a. The second pivot seat 192 is adapted to abut against the groove wall of the second clearance groove 114 to limit the rotation angle range of the second pivot seat 192.

[0244] Specifically, as shown in Figures 34 and 35, the first connecting seat 180a is generally cylindrical, and its axial direction extends approximately along the front-rear direction of the supporting device 10. The first connecting seat 180a includes a first outer connecting cylinder 181a and a first inner connecting cylinder 182a. At least a portion of the outer wall of the first outer connecting cylinder 181a is connected to the groove wall of the first clearance groove 113. The first inner connecting cylinder 182a is located inside the first outer connecting cylinder 181a and is concentrically arranged with it. The axial length of the first inner connecting cylinder 182a is greater than the axial length of the first outer connecting cylinder 181a, and the axial end of the first inner connecting cylinder 182a protrudes beyond the axial end of the first outer connecting cylinder 181a. In this embodiment, both the first outer connecting cylinder 181a and the first inner connecting cylinder 182a are positioned away from the accommodating space 101. Of course, in other embodiments, the first outer connecting cylinder 181a and the first inner connecting cylinder 182a may both be oriented towards the accommodating space 101. The central hole of the first inner connecting cylinder 182a forms a first pivot hole 1820. The first connecting seat 180a may also include a mating cylinder 184, which is located on the axial side of the first outer connecting cylinder 181a. Specifically, the mating cylinder 184 is also a cylindrical structure, and the outer peripheral wall of the mating cylinder 184 is connected to the inner peripheral wall of the first outer connecting cylinder 181a. The end of the mating cylinder 184 that protrudes from the first outer connecting cylinder 181a is provided with a first mating portion 1841. In this embodiment, the first mating portion 1841 includes a plurality of circumferentially spaced toothed protrusions 1841a. In some embodiments, the first outer connecting cylinder 181a may also be selectively omitted. In some embodiments, the first connecting seat 180a is not limited to a cylindrical structure. For example, the first connecting seat 180a can be a cylindrical structure or a square block structure, and the first mating part 1841 can be disposed on the surface of the first connecting seat 180a facing the first pivot seat 191. In some embodiments, the mating cylinder 184 can also be omitted. For example, the first mating part 1841 can be disposed on the end of the first outer connecting cylinder 181a facing the first pivot seat 191.

[0245] Specifically, as shown in Figures 34 and 35, the second connecting seat 180b is generally cylindrical in shape, and its axial direction extends approximately along the front-rear direction of the supporting device 10. The second connecting seat 180b includes a second outer connecting cylinder 181b and a second inner connecting cylinder 182b. At least a portion of the outer wall of the second outer connecting cylinder 181b is connected to the groove wall of the second clearance groove 114. The second inner connecting cylinder 182b is located inside the second outer connecting cylinder 181b and is concentrically arranged with it. The axial length of the first inner connecting cylinder 182b is greater than the axial length of the first outer connecting cylinder 181b, and one axial end of the first inner connecting cylinder 182b protrudes into one axial end of the second outer connecting cylinder 181b. In this embodiment, both the first outer connecting cylinder 181b and the second inner connecting cylinder 182b are oriented towards the accommodating space 101. Of course, in other embodiments, the second outer connecting cylinder 181b and the second inner connecting cylinder 182b may both be disposed facing away from the accommodating space 101. The central hole of the second inner connecting cylinder 182b forms a fourth pivot hole 183b. The second connecting seat 180b may also include a first connecting rib 183. There are multiple first connecting ribs 183, which connect between the first outer connecting cylinder 181b and the first inner connecting cylinder 182b. Of course, in some embodiments, the first connecting rib 183 may be omitted. In some embodiments, the second connecting seat 180b may not be limited to a cylindrical structure; for example, the second connecting seat 180b may be a cylindrical structure or a square block structure.

[0246] As shown in Figures 34 and 35, unlike the second embodiment, the mounting base 110 also includes an insertion portion 1111. A portion of the housing of the mounting base 110 protrudes downward to form the insertion portion 1111. The insertion portion 1111 is designed to engage with the slot portion 323 of the second connector 320, which will be mentioned below. In this embodiment, the insertion portion 1111 has a connection port 1112 that communicates with the mounting cavity 115, through which the hook portion 311 of the first connector 310, mentioned below, can extend out of the mounting cavity 115.

[0247] Specifically, as shown in Figures 30 and 31, each of the at least two first support rods 120a is approximately U-shaped, comprising a first top rod 121a and two first side rods 122a connected to both ends of the first top rod 121a. The ends of the two first side rods 122a away from the first top rod 121a are rotatably connected to the two mounting seats 110 respectively. Each of the at least two first support rods 120b is approximately U-shaped, comprising a second top rod 121b and two second side rods 122b connected to both ends of the second top rod 121b. The ends of the two second side rods 122b away from the second top rod 121b are rotatably connected to the two mounting seats 110 respectively. The first side rod 122a of each of the at least two first support rods 120a rotates in the same plane as the second side rod 122b of the corresponding second support rod 120b. The first top rod 121a and the first side rod 122a can be a single piece, that is, the first top rod 121a and the first side rod 122a are sections extending along different directions on the first support rod 120a. The first top rod 121a and the first side rod 122a can also be composed of multiple separate parts.

[0248] As shown in Figures 34 and 35, similar to the second embodiment, the first pivot seat 191 includes a first pivot portion 1911 and a first joint portion 1912 connected to each other. In this embodiment, the first pivot seat 191 is an integrally formed structure. In other embodiments, the first pivot seat 191 can also be formed by connecting the separate first pivot portion 1911 and the first joint portion 1912 by means of welding, keying, etc. The first pivot portion 1911 is generally a disc-shaped structure, and a second pivot hole 1910 is formed at approximately the center of the first pivot portion 1911. A second mating portion 1911a is provided on one side of the first pivot portion 1911. The first mating portion 1911a includes a plurality of toothed protrusions 1911b, which are circumferentially spaced around the second pivot hole 1910. The first pivot portion 1911 is pivotally connected to the first connecting seat 180a. The second mating portion 1911a and the first mating portion 1841 can be mated to restrict the first pivot portion 1911 relative to the mounting seat 110 at a specific angle. The first joint portion 1912 is generally a rectangular cylindrical structure. One end of the first joint portion 1912 is connected to the first pivot portion 1911, and the other end of the first joint portion 1912 has a first insertion groove 1912a. One end of the first support rod 120a is inserted into the first insertion groove 1912a. In some practical examples, the first joint portion 1912 can also be omitted, that is, the first pivot seat 191 can only include the first pivot portion 1911 and the first support rod 120a. : 120a nJ' is directly connected to the first pivot portion 1911. In this embodiment, the first outer connecting cylinder 181a and the first inner connecting cylinder 182a of the first connecting seat 180a are both disposed away from the accommodating space 101. Therefore, the first pivot seat 191 is located on the side of the first connecting seat 180a away from the accommodating space 101 so that the first pivot portion 1911 can be pivotally connected to the first connecting seat 180a.

[0249] As shown in Figures 34 and 35, the first pivot seat 192 includes a first pivot portion 1921 and a first joint portion 1922 that are interconnected. In this embodiment, the first pivot seat 192 is an integrally formed structure. In other embodiments, the first pivot seat 192 can also be formed by connecting a separate second pivot portion 1921 and a second joint portion 1922 through welding, splicing, or other methods. The second pivot portion 1921 includes an outer pivot cylinder 1921a and an inner pivot cylinder 1921b. The outer pivot cylinder 1921a is connected to the second joint portion 1922, and the inner pivot cylinder 1921b is located inside the outer pivot cylinder 1921a and is concentrically arranged with the outer pivot cylinder 1921a. One axial end of the inner pivot cylinder 1921b protrudes from one end of the outer pivot cylinder 1921a. The central hole of the inner pivot cylinder 1921b forms a third pivot hole 1920. The second pivot seat 192 may also include a first connecting rib 1923. Multiple second connecting ribs 1923 are present and connected between the outer pivot cylinder 1921a and the inner pivot cylinder 1921b. The second pivot portion 1921 is pivotally connected to the second connecting seat 180b. The second joint portion 1922 is generally a rectangular cylindrical structure; one end of the second joint portion 1922 is connected to the second pivot portion 1921, and the other end of the first joint portion 1922 has a first insertion groove 1922a. One end of the first support rod 120b is inserted into the first insertion groove 1922a. In some embodiments, the second connecting rib 1923 may be omitted. In some embodiments, the second pivot portion 1921 may not include the outer pivot cylinder 1921a and the inner pivot cylinder 1921b. Instead, the second pivot portion 1921 may be integrally cylindrical (or square columnar or polygonal columnar) in shape, with a third pivot hole 1920 formed approximately in the center. In some embodiments, the second joint portion 1922 may also be omitted, i.e., the second pivot seat 192 may only include the second pivot portion 1921, and the second support rod 120b may be directly connected to the second pivot portion 1921. In this embodiment, the first outer connecting cylinder 181b and the first inner connecting cylinder 182b of the second connecting seat 180b are both disposed facing the accommodating space 101. Therefore, the second pivot seat 192 is located on the side of the second connecting seat 180b facing the accommodating space 101 so that the second pivot portion 1921 can be pivotally connected to the second connecting seat 180b. It is worth noting that in the wooden embodiment, the second joint portion 1922 is biased away from the accommodating space 101 relative to the second pivot portion 1921, and the second joint portion 1922 and the second connecting seat 180b are arranged approximately opposite each other in the front-back direction.

[0250] In this embodiment, as shown in Figures 34 and 35, taking one side of the mounting base 110 as an example, the first pivot portion 1911 and the first connecting base 180a are pivotally connected to each other and located within the first clearance groove 113, while the second pivot portion 1921 and the second connecting base 180b are pivotally connected to each other and located within the second clearance groove 114. The first pivot portion 1911 is located on the side of the first connecting base 180a facing away from the receiving space 101, and the second pivot portion 1921 is located on the side of the second connecting base 180b facing the receiving space 101. The first pivot portion 1911 and the second connecting base 180b are generally opposite to each other in the front-back direction, and the first connecting base 180a and the second pivot portion 1921 are also generally opposite to each other in the front-back direction. As mentioned above, since the first joint 1912 and the first pivot 1911 are arranged approximately opposite each other in the front-rear direction, and the first joint 1922 and the first connecting seat 180b are also arranged approximately opposite each other in the front-rear direction, the first joint 1912 and the first pivot 1922 are also arranged approximately opposite each other in the front-rear direction. Thus, the first side rod 122a of each of the at least two first support rods 120a and the second side rod 122b of the corresponding second support rod 120b can rotate in the same plane, which is a plane approximately perpendicular to the front-rear direction. This arrangement of the first side rods 122a and the second side rods 122b, or in other words, the arrangement of the first joint 1912 and the second joint 1922, prevents the cover 130 from easily wrinkling or getting stuck during unfolding and folding.

[0251] In one embodiment, as shown in Figures 34 and 35, the body 100 may further include a first pivot 194 and a second pivot 195. The first pivot 194 passes through the first pivot seat 191 and the first connecting seat 180a to achieve the connection between the two. Specifically, the first pivot 194 passes through the first pivot portion 1911 and the first connecting seat 180a to achieve the pivot connection between the first pivot seat 191 and the first connecting seat 180a. More specifically, the first pivot seat 191 is pivotally connected to the outside of the first connecting seat 180a, that is, the side of the first connecting seat 180a facing away from the receiving space 101. The first inner connecting cylinder 182a of the first connecting seat 180a is inserted into the second pivot hole 1910 of the first pivot portion 1911. The first pivot member 194 passes through the first pivot portion 1911 and the first connecting seat 180a, or in other words, the first pivot member 194 passes through the second pivot hole 1910 and the first pivot hole 1820 to achieve the connection between the first pivot seat 191 and the first connecting seat 180a. The second pivot member 195 passes through the second pivot seat 192 and the first connecting seat 180b to achieve the connection between them. Specifically, the first pivot member 195 passes through the first pivot portion 1921 and the second connecting seat 180b to achieve the pivot connection between the second pivot seat 192 and the second connecting seat 180b. More specifically, the second pivot seat 192 is pivotally connected to the inner side of the second connecting seat 180b, that is, the side of the second connecting seat 180b facing the accommodating space 101. The inner pivot sleeve 1921b of the second pivot portion 1921 is inserted into the fourth pivot hole 183b of the connecting seat 180. The second pivot member 195 passes through the second pivot portion 1921 and the second connecting seat 180b, or in other words, the second pivot member 195 passes through the third pivot hole 1920 and the fourth pivot hole 183b to realize the connection between the second pivot seat 192 and the second connecting seat 180b.

[0252] Of course, in other embodiments, the positions of the first pivot 191 and the first connecting seat 180a can also be reversed, that is, the first pivot 191 is pivotally connected to the outside of the first connecting seat 180a, that is, the side of the first connecting seat 180a facing away from the accommodating space 101. The positions of the second pivot 192 and the second connecting seat 180b can also be reversed, that is, the second pivot 192 is pivotally connected to the inside of the second connecting seat 180b, that is, the side of the first connecting seat 180a whose surface I can accommodate the accommodating space 101.

[0253] As mentioned above, the first pivot seat 191, through the mating of the first fitting portion 1911a and the first mating portion 1841, can restrict the first pivot seat 191 relative to the mounting seat 110 at a certain positioning angle. When it is necessary to adjust the tilt angle of the first support rod 120a so that the body 100 can be opened or closed, a certain external force can be applied to the first support rod 120a, so that the toothed protrusion 1911b of the second mating portion 1911a overcomes the limitation formed by the toothed protrusion 1841a of the first mating portion 1841 (or it can be said that the second mating portion 1911a and the first mating portion 1841 push against each other and a certain degree of relative movement occurs), thereby allowing the first pivot seat 191 to rotate relative to the first connecting seat 180a (or mounting seat 110). The rotation of the first support rod 120a can cause the cover 130 to fold or unfold, and the pushing force of the first support rod 120a and / or the cover 130 can drive the first support rod 120b to rotate. Referring to Figure 34, the connection between the first joint 1922 or the second joint 1922 of the first pivot seat 192 and the first pivot 1921 can abut against one or both sides of the groove wall of the second clearance groove 114, thereby limiting the maximum rotation angle range of the second support rod 120b.

[0254] It should be noted that in some embodiments, the first mating part 1841 and the second mating part 1911a can be in other forms and are not limited to the toothed protrusions of this embodiment. For example, the first mating part 1841 is a positioning protrusion, and the second mating part 1911a is a plurality of spaced positioning recesses. The shapes of the positioning protrusion and the positioning recesses are mutually inclusive. When the positioning protrusion selectively engages with one of the plurality of positioning recesses, the first pivot seat 191 is positioned with the mounting seat 110.

[0255] In some embodiments, when the first pivot 191 needs to rotate relative to the mounting base 110, the first support rod 120a is subjected to an external force. The toothed protrusions 1911b of the second mating part 1911a and the toothed protrusions 1841a of the first mating part 1841 can be briefly deformed by their own material elasticity, thereby realizing the relative rotation of the first pivot 191 and the mounting base 110. In some embodiments, the mounting base 110 may also be provided with an elastic element (not shown), which makes the first pivot 191 tend to move in a constant direction toward the mounting base 110. For example, the elastic element is a single spring. The spring provides a constant force to the first pivot seat 191, causing the connecting seat 180 to approach. This allows the toothed protrusions 1911b of the second mating part 1911a and 1841a of the first mating part 1841 to approach and engage for positioning. The first pivot seat 191 and the connecting seat 180 can then be locked together. When the first pivot seat 191 needs to rotate relative to the mounting seat 110, it is subjected to an external force that overcomes the force of the elastic element. The elastic element deforms, allowing the first pivot seat 191 to move away from the connecting seat 180. The toothed protrusions 1911b of the second mating part 1911a and 1841a of the first mating part 1841 move away from each other, allowing the first pivot seat 191 to rotate relative to the mounting seat 110. The first pivot seat 191 can then rotate to another positioning angle position. For example, the elastic element may be located between the first connecting seat 180a and the first pivot seat 191. This elastic element is a tension spring, capable of pulling the first pivot seat 191 towards the first connecting seat 180a. Alternatively, the first pivot seat 191 may have a receiving groove on the side facing away from the first connecting seat 180a, with a cover positioned at the opening of the receiving groove. The elastic element is housed within this receiving groove. One end of the elastic element abuts against the groove wall of the receiving groove in the first pivot seat 191, and the other end abuts against the cover. This elastic element may be a compression spring, capable of applying elastic pressure to the first pivot seat 191 towards the first connecting seat 180a.

[0256] Referring to Figures 30 and 31, the first pivot 192 can rotate between a first position and a second position (or the first support rod 120b can rotate between a first position and a second position). When the body 100 is in the closed state (as shown in Figure 30), the second pivot 192 is in the first position. When the body 100 is in the open state, the second pivot 192 is in the second position. As shown in Figure 31, the body 100 is in a semi-open state, with the right side of the body 100 operated open, and both the first support rod 120a and the second support rod 120b on the right side rotate to the left to open, but the left side of the body 100 remains closed. Specifically, in this embodiment, when the body 100 is in the closed state, the second pivot 192 (or the second support rod 120b) is in a generally vertical state. The second pivot seat 192 does not abut against the groove wall of the second clearance groove 114, but due to the restriction of the cover 130, the rotation of the first pivot seat 192 is restricted, and the first pivot seat 192 remains in the first position. In this embodiment, when the body 100 is in a semi-open state, the second pivot seat 192 of the body 100 located on the open side is in the second position. Specifically, when the second pivot seat 192 rotates to the second position, the second pivot seat 192 will abut against the groove wall of the second clearance groove 114, so that the second pivot seat 192 can no longer continue to rotate, thereby restricting the rotation angle of the second pivot seat 192. The second pivot seat 192 also has a third position (or the second support rod 120b also has a third position). In this embodiment, the third position is between the first position and the third position. Referring to Figure 31, when one side of the main body 100's second support rod 120b (e.g., the first support rod 120b on the right side of Figure 31) rotates to the second position, the other side's second support rod 120b (e.g., the second support rod 120b on the left side of Figure 31) rotates to the first position. Specifically, when the main body 100 is in a semi-open state, the other side's second support rod 120b (e.g., the second support rod 120b on the left side of Figure 31) may rotate to the third position due to the pushing force generated by the closing of the cover 130 or due to the user's flicking operation. However, due to the restriction of the cover 130, the other side's second support rod 120b (e.g., the second support rod 120b on the left side of Figure 31) cannot continue to rotate after rotating to the third position, thus remaining in the third position.

[0257] Of course, in other embodiments, the first and second positions of the second support rod 120b can also be other orientations. For example, when the second support rod 120b is in the first position, it is approximately vertical; when the second support rod 120b is in the second position, it is approximately horizontal or at an angle of 135 degrees to the horizontal plane. The first and second positions are not limited to the specific positions provided in the accompanying drawings of this embodiment. In other embodiments, the second pivot seat 192 can also be maintained in the first or third position by abutting against the groove wall of the second clearance groove 114.

[0258] As shown in Figures 36 and 37, similar to the second embodiment, the base 200 includes a housing, the housing having a first cover 210 and a second cover 220. The structure of the first cover 210 in this embodiment is substantially the same as that in the first embodiment. The structure of the second cover 220 in this embodiment is also substantially the same as that in the second embodiment, with only some structural differences, which will be detailed below:

[0259] In one embodiment, as shown in Figures 40 and 41, the base 200 also includes a support member 230. The support member 230 in this embodiment has the same structure as the support member 230 in the second embodiment, and will not be described again here. As shown in Figure 38, a mat 201 can also be laid on the support member 230 to provide cushioning protection for the pet riding on it and to improve the pet's riding comfort.

[0260] Unlike the second embodiment, the first cover 220 in this embodiment does not have a limiting protrusion 221, meaning the top of the second cover 220 is relatively flat. This design is compatible with the structure of the first connecting mechanism 300 mentioned below. The two second connecting members 320 of the first connecting mechanism 300 are respectively disposed on the two opposite long sides of the second cover 220 and are arranged opposite to each other. It is worth noting that a limiting groove 223 is also formed at the edge of the second cover 220. In this embodiment, there are two limiting grooves 223, both of which are U-shaped grooves. One limiting groove 223 is disposed on the left side of the two second connecting members 320, and the other limiting groove 223 is disposed on the right side of the two second connecting members 320. As shown in Figure 30, the two first support rods 120a correspond to the two limiting grooves 223 respectively. When either of the first support rods 120a is in the first position, the first support rod 120a can be placed in the corresponding limiting groove 223. For example, when the main body 100 is in the closed state as shown in Figure 30, the two first support rods 120a are respectively placed in the corresponding limiting grooves 223. When the wooden body 100 is in the semi-open state as shown in Figure 31, the first support rod 120a on the right side moves away from the corresponding limiting groove 223, while the second support rod 120b on the left side remains in the corresponding limiting groove 223. It can be understood that the base 200 in this embodiment does not have a fixed seat 240, and the first connecting member 320 is directly set on the base 200, specifically directly set on the cover 220.

[0261] The other structures of the base 200 in this embodiment are basically the same as those of the base 200 in the second embodiment, and will not be described again here.

[0262] Similar to the second embodiment, as shown in Figures 42 to 44, this embodiment has two first connecting mechanisms 300, which are respectively disposed on opposite sides of the body 100 and the base 200. Of course, in other embodiments, the number and placement of the first connecting mechanisms 300 can be adjusted as needed; for example, four first connecting mechanisms 300 can be disposed on the four sides of the body 100 and the base 200. The first connecting structure 202 in this embodiment differs structurally from the first connecting mechanism 300 in the second embodiment. The structure of one of the first connecting mechanisms 300 will be specifically described below as an example:

[0263] As shown in Figures 42 to 44, the first connecting mechanism 300 has a locked state and an unlocked state. When the first connecting mechanism 300 is in the locked state, the body 100 is allowed to switch between an open state and a closed state to open or close the accommodating space 101. When the first connecting mechanism 300 is in the unlocked state, the body 100 and the base 200 are detachable. The first connecting mechanism 300 includes a first connector 310 and a second connector 320. The first connector 310 is movably disposed on the body 100 and can switch between a locked position and an unlocked position. The second connecting member 320 is disposed on the base 200. When the first connecting member 310 is in the locked position (i.e., the first connecting mechanism 300 is in the locked state), the first connecting member 310 and the second connecting member 320 are locked together. When the first connecting member 310 is in the unlocked position (i.e., the first connecting mechanism 300 is in the unlocked state), the first connecting member 310 and the second connecting member 320 are released from the engagement, and the base 200 and the body 100 are detachably connected through the first connecting mechanism 300. Of course, in other embodiments, the positions of the first connecting member 310 and the second connecting member 320 can also be interchanged, that is, the first connecting member 310 can be movably disposed on the base 200, and the first connecting member 320 is disposed on the body 100. In other words, the first connecting member 310 can be movably disposed on one of the base 200 and the body 100, and the first connecting member 320 is disposed on the other of the base 200 and the body 100. Optionally, when the first connector 310 is in the locked position, the first connector 310 and the second connector 320 can be engaged by insertion, snap-fit, or other methods that allow for quick assembly and disassembly.

[0264] In one embodiment, as shown in Figures 42 to 44, the first connecting mechanism 300 may further include a release member 330. In this embodiment, the first connecting member 310 and the release member 330 are connected and movably disposed within the mounting base 110. The release member 330 can be operated to move the first connecting member 310 to the unlocked position. In one embodiment, the first connecting mechanism 300 may further include a first reset member 340. The first reset member 340 is used to apply force to the release member 330 so that the release member 330 moves the first connecting member 310 to the locked position. Of course, in other embodiments, the first connecting member 310 and the release member 330 are integrally formed structures for connection. In other embodiments, they may also be separate structures and connected by fasteners (not shown) or by drive grooves (not shown) and drive columns (not shown). Specifically, as shown in Figures 42 to 44, the mounting base 110 has a mounting cavity 115, in which the first connecting member 310 and the release member 330 are at least partially movably mounted. The release member 330 includes a mounting portion 331 and a pressing portion 332 connected to each other. Both the mounting portion 331 and the pressing portion 332 are generally cylindrical, and the radial dimension of the mounting portion 331 is larger than the radial dimension of the pressing portion 332. Thus, a limiting step 333 is formed at the connection between the mounting portion 331 and the pressing portion 332. The side of the mounting base 110 facing the outside of the accommodating space 101 has an operating port 116 communicating with the mounting cavity 115, through which at least a portion of the pressing portion 332 is exposed for operation. A limiting protrusion 117 is provided on one side wall of the mounting cavity 115. This limiting protrusion 117 abuts against the limiting step 333 of the releasing member 330 to limit the movement stroke of the releasing member 330 and prevent the releasing member 330 from sliding out through the operating port 116. A mounting hole 3311 is provided on the side of the mounting part 331 facing away from the operating port 116. The first reset member 340 is at least partially installed in the mounting hole 3311. Specifically, the first reset member 340 is a spring. A first limiting part 3312 is provided on the bottom wall of the mounting hole 3311. The first reset member 340 is sleeved on the first limiting part 3312. One end of the first reset member 340 abuts against the bottom wall of the mounting hole 3311, and the other end of the first reset member 340 abuts against the cavity wall of the mounting cavity 115 facing the operating port 116. In this way, the first reset member 340 can be prevented from shifting during deformation.

[0265] In one embodiment, as shown in Figures 42 to 44, the cavity wall of the mounting cavity 115 facing the operating port 116 is provided with a second limiting portion 118 opposite to the first limiting portion 3312. In this embodiment, the first limiting portion 3312 is a limiting post 3312, and the second limiting portion 118 is a limiting hole 118 that is inserted and fitted with the limiting post 3312. The limiting post 3312 extends along the direction in which the pressing portion 332 is pressed. Specifically, the limiting post 3312 includes a first post 3313 and a second post 3314 connected to each other. The end of the first post 3313 away from the second post 3314 is connected to the bottom wall of the mounting hole 3311. The end of the second post 3314 away from the first post 3313 protrudes from the mounting hole 3311 and is used to be inserted into the limiting hole 118, thereby restricting the movement of the release member 330 and the first connecting member 310. In this embodiment, the radial dimension of the first post 3313 is larger than the radial dimension of the second post 3314. The larger radial dimension of the first post 3313 facilitates the fitting of the first reset member 340 to prevent displacement of the first reset member 340 during deformation. The smaller radial dimension of the second post 3314 facilitates insertion into the limiting hole 118. In another embodiment, the first connector 310 is further provided with a guide protrusion 312, and the cavity wall of the mounting cavity 115 facing the operating port 116 is provided with a guide hole 1113 opposite to the guide protrusion 312. The guide protrusion 312 is adapted to be inserted into the guide hole 1113 to guide the movement direction of the first connector 310 and the unlocking member 330. The first connecting mechanism 300 also includes a limiting pin 350, which is generally T-shaped and includes a pin body 351 and a stop portion 352 that are connected to each other and set at a certain angle. The guide protrusion 312 has a fixing groove 3121. The pin body 351 of the limiting pin 350 is inserted and fixed in the fixing groove 3121. The abutment portion 352 of the limiting pin 350 is located outside the mounting cavity 115, and the dimension of the abutment portion 352 in the direction perpendicular to the limiting pin 350 is larger than the dimension of the guide protrusion 312 in that direction, and also larger than the diameter of the guide hole 1113 in that direction. Thus, the abutment portion 352 abuts against the groove wall of the mounting base 110 to limit the travel of the first connecting member 310 and the unlocking member 330.

[0266] In one embodiment, as shown in Figures 42 to 44, the housing structure of the mounting base 110 can be divided into a main body portion mo and an insertion portion mi, with the insertion portion 1111 located below the main body portion mo. The interiors of the main body portion mo and the insertion portion mo are connected by a mounting cavity 115. The mounting cavity 115 located within the main body portion 1110 is designated as cavity 1151, and the mounting cavity 115 located within the insertion portion 1111 is designated as cavity 1152. The connection port 1112 of the insertion portion 1111 communicates with the cavity 1152. A first connector 310 is at least partially movably disposed within a second cavity 1152. One end of the first connector 310 extends into the first cavity 1151 to connect with the mounting portion 331 of the release member 330. The other end of the first connector 310 forms a hook portion 311, which is adapted to extend out of the second cavity 1152 (or mounting cavity 115) through a connection port 1112. In this embodiment, the first connector 310 has a strip-shaped structure, and the hook portion 311 is configured to face the outer side of the base 200. In other embodiments, the hook portion 311 may also be configured to face the inner side of the base 200.

[0267] In one embodiment, as shown in Figures 42 to 44, the second connector 320 is provided with a slot portion 323 that can be inserted and engaged with the insertion portion 1111. The insertion portion 1111 is inserted into the slot portion 323. When the first connector 310 is in the locked position, the first connector 310 can be locked and engaged with the first connector 320. In this embodiment, the first connector 320 is embedded in the first cover 220, and the upper surface of the second connector 320 is flush with the upper surface of the second cover 220. The slot portion 323 is formed on the upper surface of the second connector 320 and extends downward. The first connector 310 has a hook portion 311, and the second connector 320 has a groove portion 3211. The groove portion 3211 is provided on the side wall of the slot portion 323. When the insertion portion 1111 is inserted into the slot portion 323 and the first connector 310 is in the locked position, the hook portion 311 can engage with the groove portion 3211. Specifically, the groove portion 3211 is provided on the side wall of the slot portion 323 away from the receiving space 101.

[0268] In one embodiment, as shown in Figures 42 to 44, the first connecting mechanism 300 further includes a closing cover 370, which is switchable between a closed position and an exposed position. When the closing cover 370 is in the closed position, it can close the slot of the slot portion 323, thus preventing dust from falling into the slot portion 323 when the base 200 is used alone. When the closing cover 370 is in the exposed position, it moves away from the slot of the slot portion 323, allowing the first connector 310 to connect with the second connector 320. In a further embodiment, the first connecting mechanism 300 also includes a first reset member 380, which is located in the slot portion 323, and both ends of the second reset member 380 abut against the bottom of the slot portion 323 and the closing cover 370, respectively. In this embodiment, the second reset member 380 is a spring. The bottom of the slot portion 323 is provided with a first limiting protrusion 324, and the side of the closing cover 370 facing the second reset member 380 is provided with a second limiting protrusion 371. One end of the second reset member 380 is fitted onto the first limiting protrusion 324 and abuts against the bottom of the slot portion 323, while the other end of the second reset member 380 is fitted onto the second limiting protrusion 371 and abuts against the closing cover 370, thus preventing the second reset member 380 from shifting.

[0269] The supporting device 10 proposed in this invention has at least the following technical effects: a accommodating space 101 for accommodating pets is formed between the main body 100 and the base 200. A first connecting mechanism 300 is provided between the main body 100 and the base 200. The first connecting mechanism 300 includes a first connecting member 310 disposed on the base 200 or the main body 100 and a second connecting member 320 disposed on the main body 100 or the base 200. The base 200 and the main body 100 can be detachably connected by locking and unlocking the first connecting member 310 and the second connecting member 320, without the need for a long zipper structure to achieve detachable connection. This allows for convenient and quick disassembly between the main body 100 and the base 200, enabling pets to be quickly moved in or out, which is especially suitable for injured pets and improves the efficiency of pet treatment.

[0270] Fourth embodiment

[0271] As shown in Figures 46 and 47, a fourth embodiment of the present invention provides a carrying device 10X, which can be used to carry pets, etc. Specifically, the carrying device 10X includes a body assembly 100X and a base assembly 200X. The body assembly 100X (which may also be referred to as the body in other embodiments) and the base assembly 200X (which may also be referred to as the base in other embodiments) enclose a space (not shown in the figures) that can be used to carry pets. In this embodiment, the body assembly 100X is a canopy-type box. The body assembly 100X specifically includes a mounting base 110X, a plurality of support rods 120X, and a cover 130X. At least one end of the plurality of support rods 120X is connected to the mounting base 110X, and the cover 130X is connected to the plurality of support rods 120X to form a box-shaped structure with a rectangular opening at the bottom. The cover 130X can be a tarpaulin or plastic, etc. Of course, in other embodiments, the body assembly 100X can be a common fixed-shape box 100, such as a hexahedral box 100. Further, the body assembly 100X may also include a handle 140X. The handle 140X can be a long strip made of leather or fabric, with both ends of the handle 140X sewn onto the cover 130X. In this embodiment, the base assembly 200X includes a base 210X, which is a shell structure with a generally rectangular cross-section.

[0272] Furthermore, the carrier device 10X also includes a moving mechanism 300X disposed on the base assembly 200X. The moving mechanism 300X can switch between a use state and a folded state. As shown in Figure 46, when the moving mechanism 300X is in the use state, the carrier device 10X is in a first use mode. In the first use mode, the carrier device 10X can be moved by the moving mechanism 300X, thereby making the handling of the carrier device 10X more convenient and labor-saving. As shown in Figure 47, when the moving mechanism 300X is in the folded state, the carrier device 10X is in the first use mode. In the second use mode, the carrier device 10X can be placed on a flat surface, such as on a car seat 20X in a car (as shown in Figure 48), thereby facilitating the storage and transportation of the carrier device 10X. It can also be moved by placing it on other moving devices, or carried by the handle 140X.

[0273] As shown in Figure 48, the car seat 20X may include a seat portion 21X and a backrest portion 22X connected to each other at a certain angle, forming a placement space between the seat portion 21X and the backrest portion 22X (not shown in the figure). In a second usage mode, the support device 10X can be placed on the top plane of the seat portion 21X and fixed to the car seat 20X by a connecting assembly 30X. Specifically, the connecting assembly 30X may include, for example, an interconnected restraint strap 31X and a fastener 32X. The restraint strap 31X is wrapped around and restrained outside the support device 10X, and the end of the fastener 32X away from the restraint strap 31X is fixed to the backrest portion 22X. In this embodiment, the fastener 32X may be a snap hook. Of course, in other embodiments, the fastener 32X may also be a clamp or other structure.

[0274] It should be noted that the following description of the embodiments will use directional terms such as "front," "rear," "left," "right," "up," and "down." In this embodiment, the directional terms "front," "rear," "left," "right," "up," and "down" of the supporting device 10X correspond to the "front," "rear," "left," "up," and "down" directions of the car seat 20X (as shown in Figure 48). The "front," "rear," "left," "right," "up," and "down" directions are schematically indicated by arrows F, B, L, R, U, and D in the figure. These directional terms are only used to make the technical solution description of the embodiments of the present invention clearer and are not intended to unduly limit the scope of protection of the present invention.

[0275] As shown in Figures 49 to 51, there are two moving mechanisms 300X, which are respectively and spaced apart on the bottom surface 201X of the base assembly 200X. In this embodiment, both moving mechanisms 300X extend approximately along the long side of the bottom surface 201X of the base assembly 200X (i.e., the left-right direction in this embodiment). Of course, in other embodiments, the number and position of the moving mechanisms 300X can be adjusted as needed. For example, three moving mechanisms 300X can be provided, all of which extend approximately along the short side of the base assembly 200X (i.e., the front-back direction in this embodiment).

[0276] The following description uses one of the mobile mechanisms, 300X, as an example to illustrate its structure and connection relationships:

[0277] As shown in Figure 49, the moving mechanism 300X includes wheel assemblies 310X mounted on the base assembly 200X. The wheel assemblies 310X are switchable between a used position and a folded position. Switching between the used and folded positions allows the moving mechanism 300X to switch between its used and folded states. In this embodiment, each moving mechanism 300X has two wheel assemblies 310X, each located at one of the two apex corners of the bottom surface 201X of the base assembly 200X. That is, the four wheel assemblies 310X of the two moving mechanisms 300X are located at the four apex corners of the bottom surface 201X of the base assembly 200X. This arrangement allows for smoother movement of the supporting device 10X. Of course, in other embodiments, the number and position of the wheel assemblies 310X can be adjusted as needed.

[0278] Taking one wheel assembly 310X as an example, as shown in Figure 49, in this embodiment, the wheel assembly 310X may specifically include a roller 311X, a wheel axle 312X, and a wheel seat 313X. The wheel seat 313X includes a connector 3131X and a pivot member 3132X connected to each other. In this embodiment, the connector 3131X may be generally cylindrical in shape, and the connector 3131X is provided with an insertion groove 3130X extending along its axial direction. The insertion groove 3130X is adapted to be inserted and connected to the mounting rod 320X (see below for details). The pivot member 3132X is generally U-shaped, including two mounting portions 3132aX disposed opposite each other and a connecting portion 3132bX connected between the two mounting portions 3132aX. The connecting portion 3132bX is adapted to be connected to the side wall of the connector 3131X. The roller 311X is located between the two mounting portions 3132aX, and the hub center of the roller 311X is pivotally connected to the end of the two mounting portions 3132aX away from the connecting portion 3132bX via the axle 312X. In this example, the connecting portion 3132bX is rotatably connected to the side wall of the connecting member 3131X, and the connecting portion 3132bX can rotate 360 ​​degrees relative to the connecting member 3131X, thereby enabling the roller 311X to rotate in all directions.

[0279] In some embodiments not shown, the connecting portion 3132bX and the connecting member 3131X may also be fixedly connected. Alternatively, in other embodiments not shown, the wheel seat 313X may only include the pivot member 3132X, that is, the connecting member 3131X may be omitted, and the pivot member 3132X may be directly connected to the mounting rod 320X.

[0280] Furthermore, the moving mechanism 300X also includes a mounting rod 320X. The mounting rod 320X is rotatably mounted on the bottom surface 201X of the base assembly 200X. Both ends of the mounting rod 320X are respectively inserted into the insertion slots 3130X of the connectors 3131X of the two wheel seats 313X, thereby connecting the mounting rod 320X to the two wheel assemblies 310X. Thus, the wheel cover 310X can be switched between a used position and a folded position by rotating the mounting rod 320X relative to the base assembly 200X.

[0281] Of course, in some unseen embodiments, the mounting rod 320X and the wheel seat 313X can also be connected in other ways, such as the wheel seat 313X can be directly fixed to both ends of the mounting rod 320X by means of welding or keying.

[0282] Furthermore, the base assembly 200X may also include a mounting member 220X. The mounting member 220X is fixed to the bottom surface 201X of the base assembly 200X, and extends approximately along the long side of the bottom surface 201X of the base assembly 200X. In this embodiment, the mounting member 220X is generally a cylindrical structure with both ends open. Part of the sidewall of the mounting member 220X is fixed to the bottom surface 201X of the base assembly 200X, and a mounting cavity 221X is formed inside the mounting member 220X. The mounting rod 320X passes through the mounting member 220X and can rotate relative to the mounting member 220X. In this embodiment, the mounting member 220X is fitted around approximately the middle half of the mounting rod 320X. This arrangement can save manufacturing materials while achieving a rotatable connection between the mounting rod 320X and the mounting member 220X. Of course, in some embodiments not shown, the mounting member 220X may also be fitted around almost the entire mounting rod 320X. In other embodiments not shown, the mounting member 220X may also be a cylindrical structure with both ends open, etc.

[0283] In this embodiment, when the wheel assembly 310X is in the use position, it is far from the bottom surface 201X of the base assembly 200X; when the wheel assembly 310X is in the folded position, it is close to the bottom surface 201X of the base assembly 200X. Specifically, as shown in FIG49, when the wheel assembly 310X is in the use position, the roller 311X is approximately located directly below the connector 3131X and far from the bottom surface 201X of the base assembly 200X, or equivalently, the roller 311X is located below the mounting rod 320X. In this use position, the roller 311X in the wheel assembly 310X can move the bearing device 10X by rolling. As shown in Figures 50 and 51, when the wheel assembly 310X is in the folded position, the roller 311X is approximately located on the side of the connector 3131X and close to the bottom surface 201X of the base assembly 200X. Alternatively, the roller 311X can be positioned on the side of the mounting rod 320X. In this embodiment, the roller 311X is located inside the connector 3131X, that is, at the edge of the roller 311X away from the base assembly 200X relative to the connector 3131X. This is equivalent to the wheel assembly 310X folding towards the bottom surface 201X of the base assembly 200X, and the thickness of the wheel assembly 310X in the folded position is no greater than the width of the mounting rod 320X. This allows the support device 10X to be stably placed on a flat surface such as a car seat 20X.

[0284] In this embodiment, as shown in Figure 49, when the wheel assembly 310X is in the working position, the mounting rod 320X corresponding to the wheel assembly 310X rotates approximately 90 degrees around its own central axis in the direction of S1, which can drive the wheel assembly 310X to switch from the working position to the folded position. As shown in Figure 50, when the wheel assembly 310X is in the folded position, the mounting rod 320X corresponding to the wheel assembly 310X rotates approximately 90 degrees around its own central axis in the opposite direction of S1, which can drive the wheel assembly 310X to switch from the folded position to the working position.

[0285] Furthermore, when the moving mechanism 300X is in the folded state, the mounting rod 320X can engage with the engaging mechanism (not shown in the attached figure) on the moving device, thereby fixing the bearing device 10X to the moving device.

[0286] Further, as shown in Figures 53 and 54, the supporting device 10X may also include a locking mechanism 400X. The locking mechanism 400X is disposed between the wheel assembly 310X and the base assembly 200X, and can selectively lock the wheel assembly 310X in either the use position or the folded position. The locking mechanism 400X can take various forms; for example, in this embodiment, the locking mechanism 400X may include a locking pin 410X disposed on the base assembly 200X and a first locking hole 401X and a second locking hole 402X disposed on the mounting rod 320X. The locking pin 410X is switchable between a locked position and an unlocked position. When in the locked position, the locking pin 410X is suitable for insertion into the first locking hole 401X or the second locking hole 402X to lock the wheel assembly 310X in either the use position or the folded position. When the locking pin 410X is in the unlocked position, it is adapted to be removed from the first locking hole 401X or the second locking hole 402X to release the locking of the coupling assembly 310X in the used or folded position. Specifically, the locking pin 410X is, for example, movably disposed within the receiving groove 213X of the base 210X, and the side of the mounting member 220X connected to the base 210X is provided with a groove communicating with the receiving groove 213X.

[0287] The connecting hole 222X. When the locking pin 410X is in the locked position, the locking pin 410X, which was originally located in the receiving groove 213X, moves downward (i.e., in the D1 direction in Figure 55) out of the receiving groove 213X and passes through the connecting hole 222X into the mounting cavity 221X of the mounting member 220X. If the moving mechanism 300X is rotated to the working state, the first locking hole 401X is opposite to the connecting hole 222X, and the locking pin 410X can be inserted into the first locking hole 401X to lock the moving mechanism 300X in the working state. If the moving mechanism 300X is rotated to the folded state, the second locking hole 402X is opposite to the connecting hole 222X, and the locking pin 410X can be inserted into the second locking hole 402X to lock the moving mechanism 300X in the folded state.

[0288] Furthermore, as shown in Figures 53 and 54, the locking mechanism 400X may also include a locking reset member 420X. The locking reset member 420X is disposed between the base assembly 200X and the locking pin 410X, and is adapted to apply force to the locking pin 410X to move it to the locked position. The locking reset member 420X can be a spring, a spring sheet, or other elastic element. In this embodiment, the locking reset member 420X is a spring. The locking reset member 420X is specifically disposed within the receiving groove 213X, with both ends of the locking reset member 420X abutting against the bottom of the receiving groove 213X and the locking pin 410X, respectively, to apply a force to the locking pin 410X to move it to the locked position. Thus, the locking reset member 420X can hold the locking pin 410X in the locked position. Further, as shown in Figures 53 and 54, the locking mechanism 400X may also include a release operation member 430X. The release operation member 430X is operably disposed on the base assembly 200X. The release operation member 430X is drivenly connected to the locking pin 410X, and the release operation member 430X can be operated to drive the locking pin 410X from the locked position to the released position. The locking mechanism 400X may further include a drive member 440X, which is connected between the locking pin 410X and the release operation member 430X. When the release operation member 430X is operated, it can actuate the locking pin 410X through the drive member 440X, so that the locking pin 410X moves from the locked position to the released position. In this embodiment, the drive member 440X is a rod-shaped structure. The drive member 440X is disposed within the receiving groove 213X, and its approximate center is pivotally connected to the base 210X at a first pivot point O. One end of the drive member 440X is pivotally connected to the locking pin 410X at a second pivot point M, and the other end of the drive member 440X is pivotally connected to the release operation member 430X at a third pivot point N. That is, the drive member 440X, the locking pin 410X, and the release operation member 430X form a seesaw-like structure. In this embodiment, the release mechanism 430X is a pull rod, including a rod portion 43IX and a pull ring 432X connected to each other. The base 210X also has an operating hole (not shown in the figure) communicating with the receiving groove 213X. At least a portion of the rod portion 43IX extends into the receiving groove 213X through the operating hole and is pivotally connected to the drive member 440X. At least a portion of the pull ring 432X is exposed outside the base 210X through the operating hole so that it can be pulled downward (i.e., in the D1 direction in FIG. 53). The extending direction of the locking pin 410X is generally parallel to the extending direction of the release mechanism 430X.Furthermore, the locking mechanism 400X may also include an operation reset member 450X, which is adapted to apply force to the release operation member 430X to reset it. In this embodiment, the operation reset member 450X is a tension spring, with both ends of the tension spring connected to the bottom of the receiving groove 213X and the end of the rod 431X away from the pull ring 432X, respectively. Specifically, a fixing ring 212X may be provided at the bottom of the receiving groove 213X, and a fixing hole 4310X may be provided at the end of the rod 431X away from the pull ring 432X. The connecting rings at both ends of the tension spring may be connected to the fixing ring 212X and the fixing hole 4310X, respectively.

[0289] Thus, when it is necessary to switch the moving mechanism 300X between the use state and the folded state, as shown in Figure 53, the release operation member 430X can be pulled along the D1 direction, causing the drive member 440X to rotate along the clockwise direction (i.e., the R1 direction in Figure 53). At this time, the operation reset member 450X is stretched and deformed. During the rotation of the drive member 440X, the locking pin 410X moves in the opposite direction of the D1 direction, and the locking reset member 420X is compressed and deformed. When the locking pin 410X moves from the locked position shown in Figure 53 to the unlocked position shown in Figure 54, the locking mechanism 400X releases the lock on the moving mechanism 300X in the use state or the folded state, allowing the mounting rod 320X to rotate relative to the base assembly 200X, that is, the moving mechanism 300X can rotate between the use state and the folded state. When the moving mechanism 300X is rotated to the desired operating or folded state, the first locking hole 401X or the second locking hole 402X aligns with the connecting hole 222X on the mounting member 220X. At this time, the tension applied to the release operating member 430X is removed, and the release operating member 430X moves in the opposite direction of D1 under the elastic restoring force of the operating reset member 450X, thus resetting. Simultaneously, the release operating member 430X drives the driving member 440X to rotate in the reverse direction (i.e., the opposite direction of R1 in Figure 54). When the driving member 440X rotates, it drives the locking pin 410X to move in the D1 direction, and the elastic restoring force of the locking reset member 420X also drives the locking pin 410X to move in the D1 direction. When the locking pin 410X moves to the locked position, the locking pin 410X is inserted into the first locking hole 401X or the second locking hole 402X through the connecting hole 222X, thereby locking the moving mechanism 300X in the use state and the folded state.

[0290] In some embodiments, the positions of the locking pin 410X and the two locking holes (including the first locking hole 401X and the second locking hole 402X) can also be reversed, that is, the locking pin 410X can be set on the mounting rod 320X, and the first locking hole 401X and the second locking hole 402X can be set on the base assembly 200X. The setting positions and methods of the related release operation member 430X, drive member 440X, locking reset member 420X and operation reset member 450X can also be adjusted accordingly.

[0291] In some embodiments, the drive element 440X may be omitted, and the release operation element 430X may be directly driven to the locking pin 410X.

[0292] In some embodiments, the operation reset member 450X may also be omitted. When the force applied to the release operation member 430X is removed, the locking pin 410X is reset to the locked position only by the elastic restoring force of the locking reset member 420X. At the same time, the locking pin 410X drives the release operation member 430X to reset through the drive member 440X.

[0293] Further, as shown in FIG52, the supporting device 10X may also include a movable member 500X. The movable member 500X is movably connected to the base assembly 200X and can switch between a push-pull position and a retracted position. When the movable member 500X is in the push-pull position, it is adapted to be pulled so that the supporting device 10X moves via the moving mechanism 300X. When the movable member 500X is in the retracted position, it is adapted to be retracted within the base assembly 200X. In this embodiment, the movable member 500X is a drag bar 500. When the movable member 500X is in the push-pull position and the moving mechanism 300X is in use, it is adapted to be dragged to drive the supporting device 10X to slide. In other embodiments, the movable member 500X may also be a pull rope or other structures.

[0294] Specifically, as shown in Figure 52, the movable component 500X includes a handle 510X and a rod 520X connected to each other. In this embodiment, the movable component 500X is a monolithic structure. In other embodiments, the movable component 500X can also be formed by connecting the independent handle 510X and rod 520X through welding, welding, or fasteners. In this embodiment, the handle 510X is generally a square ring structure for easy gripping by the user. Of course, in other embodiments, the shape of the handle 510X can also be other, such as a circular ring structure or an elliptical ring structure, or the handle 510X can be a straight rod directly opposite the rod 431X. The end of the rod 431X away from the handle 510X protrudes upward to form a pivot portion 521X. The movable component 500X is pivotally connected to the base assembly 200X through the pivot portion 521X.

[0295] Further, as shown in Figures 51 and 52, the base 210X has a storage cavity 214X extending parallel to its long side in approximately its center. One end of the storage cavity 214X passes through one side of the base 210X to form a storage opening 215X. In other words, the base 210X has a storage door 215X communicating with the storage cavity 214X. When the moving member 500X is in the stored position, the moving member 500X is stored in the storage cavity 214X. In this embodiment, when the moving member 500X is in the stored position, the rod portion 43IX of the moving member 500X is almost entirely contained within the storage cavity 214X, and the handle 510X of the moving member 500X is at least partially exposed outside the storage cavity 214X through the storage opening 215X so that it can be pulled out. When the movable member 500X is in the second position, it is adapted to be pulled out of the storage cavity 214X through the storage opening 215X. In this example, the movable member 500X also has a withdrawn position. The movable member 500X is movable between the storage position and the withdrawn position. When the movable member 500X is in the withdrawn position, it is almost entirely outside the storage cavity 214X, and is approximately parallel to the bottom 201X of the base 210X or to the surface on which it is placed (such as the ground). At this time, the pivot portion 521X of the movable member 500X can be pivotally connected to the base 210X. The pivot portion 521X of the movable member 500X can be pivotally connected to the base 210X so that the movable member 500X can rotate between the withdrawn position and the push-pull position.

[0296] Further, as shown in Figures 52 and 57, the supporting device 10X may also include a pivoting mechanism 600X. The pivoting mechanism 600X is disposed between the base assembly 200X and the movable member 500X. The movable member 500X is selectively pivotally connected to the base assembly 200X via the pivoting mechanism 600X to rotate between a push-pull position and a move-out position. The pivoting mechanism 600X can take various forms. In this embodiment, the pivoting mechanism 600X includes a pivot shaft 610X disposed on the base 210X and a pivot hole 620X disposed on the movable member 500X. When the movable member 500X moves from the storage position to the move-out position, the pivot shaft 610X and the pivot hole 620X engage to achieve pivoting between the movable member 500X and the base assembly 200X, allowing the movable member 500X to switch between a push-pull position and a move-out position. When the movable part 500X rotates from the push-pull position to the moved-out position, the pivot shaft 610X and the pivot hole 620X are disengaged so that the movable part 500X and the base 210X are disengaged, so that the movable part 500X can be moved to the storage position, that is, stored in the mounting cavity 22 IX of the base 210X.

[0297] Specifically, as shown in Figure 52, the pivot shaft 610X includes two pivot half-shafts 611X, which are disposed opposite to each other on the base assembly 200X. In this embodiment, one end of each of the two pivot half-shafts 611X is connected to the opposite side walls of the receiving opening 215X, and the other ends of the two pivot half-shafts 611X are disposed opposite to each other. Each pivot half-shaft 611X can be switched between a pivot position and a clearance position. A pivot hole 620X is provided in the pivot portion 521X of the moving member 500X, and the pivot hole 620X penetrates the rod 520X in the front-back direction. Of course, in other embodiments, the pivot hole 620X may not penetrate the rod 520X, but rather one pivot hole 620X may be provided on each of the front and rear sides of the rod 520X, and these two pivot holes 620X are not connected.

[0298] In this embodiment, as shown in Figures 52 and 57, when both pivot half-shafts 611X are in the pivot position, they are adapted to be inserted into the pivot hole 620X to pivotally connect the movable member 500X to the base assembly 200X. At this time, the two pivot half-shafts 611X are generally arranged along the front-back direction. In this embodiment, the opposite side walls of the storage opening 215X are parallel to each other, and the two pivot half-shafts 611X in the pivot position are respectively approximately perpendicular to the side wall of their respective connected storage openings 215X. When both pivot half-shafts 611X are in the clearance position, they are adapted to be withdrawn from the pivot hole 620X to disengage the movable member 500X and the base assembly 200X. At this time, both pivot half-shafts 611X are generally arranged parallel to the front-back direction. In this embodiment, the two pivot half-shafts 611X in the avoidance position are respectively approximately perpendicular to the sidewalls of their respective connected storage openings 215X. In other embodiments, the two pivot half-shafts 611X in the avoidance position may also be respectively approximately inclined to the sidewalls of their respective connected storage openings 215X. Specifically, as shown in Figures 52 and 55, the pivoting device further includes a pivot reset member 630X. In this embodiment, there are two pivot reset members 630X, which are respectively disposed between the two pivot half-shafts 611X and the base assembly 200X. The pivot reset member 630X is adapted to apply force to the pivot half-shafts 611X to hold them in the pivoted position. The base 210X may be provided with two receiving cavities 216X. In this embodiment, the two receiving cavities 216X are respectively located on both sides of the storage cavity 214X and on the side of the base 210X closer to the storage opening 215X. Two pivotal reset elements 630X are respectively disposed within two accommodating cavities 216X. The structure and connection relationship of one of the pivotal reset elements 630X and its corresponding pivotal half-shaft 611X are described in detail below:

[0299] As shown in Figure 55, one side wall of the receiving opening 215X is provided with a first through hole 2171X that communicates with the receiving cavity 216X. One end of the pivoting half-shaft 611X is movably inserted into the receiving cavity 216X through the first through hole 2171X. In this embodiment, the portion of the pivoting half-shaft 611X inserted into the receiving cavity 216X has a protruding limiting part 6111X. The maximum width of the limiting part 6111X is greater than the diameter of the first through hole 2171X, thereby preventing the pivoting half-shaft 611X from detaching from the base 210X. In this embodiment, the pivoting reset member 630X is a spring. Specifically, the bottom of the receiving groove 213X is provided with a sleeve post 218X. One end of the pivot reset member 630X is sleeved on the sleeve post 218X and abuts against the bottom of the receiving groove 213X. The other end of the pivot reset member 630X is sleeved on the end of the pivot half-shaft 611X that is inserted into the receiving groove 213X and abuts against the limiting part 6111X. The pivot reset member 630X is adapted to be hydraulically applied to the pivot half-shaft 611X by the limiting part 6111X to keep it in the pivot position.

[0300] As shown in Figures 52 and 55, the pivoting mechanism 600X further includes a pivoting operating member 640X. In this embodiment, there are two pivoting operating members 640X, which are driven connected to two pivoting half-shafts 611X respectively. Taking one of the pivoting operating members 640X as an example, the pivoting operating member 640X includes a connecting rod 641X and an operating rod 642X connected to each other. The base 210X is also provided with a second through hole 2172X communicating with the accommodating cavity 216X. The end of the connecting rod 641X away from the operating rod 642X extends into the accommodating cavity 216X through the second through hole 2172X and connects to the pivoting half-shaft 611X. In this embodiment, the first through hole 2172X is a strip-shaped hole extending in the front-back direction. The operating rod 642X is located outside the accommodating cavity 216X for operation. In this embodiment, the operating rod 642X is set approximately perpendicular to the connecting rod 641X. Of course, in other embodiments, the pivoting operating member 640X can also take other forms, such as a structure similar to the release operating member 430X, etc., and the present invention is not limited thereto. The pivoting operating member 640X can be operated to move the pivoting half-shaft 611X from the pivoting position to the avoidance position. In this embodiment, when the pivoting half-shaft 611X is in the avoidance position, most of the pivoting half-shaft 611X is located within the receiving groove 213X to avoid the moving member 500X.

[0301] Thus, when the supporting device 10X needs to switch from the first usage mode to the second usage mode, the movable member 500X can first be rotated clockwise (i.e., the R2 direction in Figure 52) from the push-pull position to the moved-out position. Then, the pivoting operating member 640X is pushed forward and backward (i.e., the D2 direction in Figure 55), as shown in Figure 55, so that the pivoting operating member 640X drives the pivoting half-shaft 611X to move from the pivoting position to the clearance position. At this time, the pivoting reset member 630X is compressed and deformed, and the movable member 500X is disengaged from the base 210X. At this time, the movable member 500X can be pushed to the left (i.e., the D3 direction in Figure 52), so that the movable member 500X moves from the moved-out position to the storage position, so that most of the rod 520X of the movable member 500X is stored in the receiving cavity 216X. Furthermore, a positioning hole 522X can be provided on the rod 520X near the handle 510X. The positioning hole 522X also penetrates the rod 520X in the front-to-back direction. When the movable member 500X moves to the storage position, the positioning hole 522X is positioned opposite to the two pivot half-shafts 611X. At this time, the pivot operating member 640X can be released, so that the two pivot half-shafts 611X are inserted into the positioning hole 522X under the elastic restoring force of the corresponding pivot reset member 630X, as shown in Figure 56, thereby locking the movable member 500X in the storage position and preventing the movable member 500X from falling out of the storage cavity 214X. Of course, in other embodiments, the positioning hole 522X may not penetrate the rod 520X, but rather one positioning hole 522X may be provided on each of the front and rear sides of the rod 520X, and these two positioning holes 522X are not connected.

[0302] When the support device 10X needs to switch from the second usage mode to the first usage mode, the pivot operating member 640X can be pushed in the forward / backward direction (i.e., the D2 direction in Figure 55) to move the pivot half-shaft 611X from the pivot position to the clearance position, that is, both pivot half-shafts 611X are disengaged from the positioning hole 522X. At this time, the pivot reset member 630X is compressed and deformed, as shown in Figure 56. Then, the moving member 500X can be pushed to the left (i.e., the opposite direction of the D3 direction in Figure 52) to move the moving member 500X from the storage position to the removal position, that is, the rod 520X of the moving member 500X is translated out of the receiving cavity 216X. At this time, the pivot hole 620X of the moving member 500X is opposite to the two pivot half-shafts 611X. At this point, the pivoting operating member 640X is released, and the two pivoting half-shafts 611X are inserted into the pivoting hole 620X under the elastic restoring force of the pivoting reset member 630X, thereby realizing the pivoting of the moving member 500X and the base 210X, as shown in Figure 55. Then, the moving member 500X can be rotated from the moved-out position in a counterclockwise direction (i.e., the opposite direction of R2 in Figure 52) back to the moved-out position, thereby facilitating the user to pull the bearing device 10X.

[0303] In some embodiments, the positions of the pivot half-shaft 611X and the pivot hole 620X can also be interchanged. That is, two pivot half-shafts 611X can be provided on the front and rear sides of the pivot part 521X respectively, and two pivot holes 620X can be provided on the two opposite side walls of the storage opening 215X of the base 210X respectively.

[0304] In some embodiments, the pivot reset member 630X may also be, for example, a torsion spring. The two pivot half shafts 611X are rotatably disposed on the two opposite side walls of the receiving port 215X. The torsion spring holds the two pivot half shafts 611X in the pivot position. The two pivot half shafts 611X can be rotated from the pivot position to the avoidance position by the pushing of the pivot part 521X against the two pivot half shafts 611X.

[0305] In some embodiments, only one pivoting actuator 640X may be provided, which is drivenly connected to two pivoting half-shafts 611X respectively through related drive mechanisms. This allows for the simultaneous control of two pivoting half-shafts 611X by a single pivoting actuator 640X.

[0306] Fifth embodiment

[0307] As shown in Figure 57, the fifth embodiment of the present invention provides a supporting device 10X. This supporting device 10X includes a body assembly 100X, a base assembly 200X, and a moving mechanism 300X. The structure and connection relationship of the body assembly 100X and the base assembly 200X in this embodiment are largely the same as in the fourth embodiment, and will not be described in detail here. The main difference between the supporting device 10X in this embodiment and the supporting device 10X in the fourth embodiment lies in the moving mechanism 300X.

[0308] As shown in Figures 58 to 61, similar to the fourth embodiment, there are also two moving mechanisms 300X in this embodiment, and each moving mechanism 300X also includes a wheel assembly 310X and a mounting rod 320X. The base assembly 200X also includes a base 210X and a mounting member 220X disposed on the bottom surface 201X of the base 210X. The difference from the fourth embodiment is that in this embodiment, the two mounting members 220X extend along the short side direction (front-back direction) of the bottom surface 201X of the base 210X, and correspondingly, the two mounting rods 320X also extend along the short side direction (front-back direction) of the bottom surface 201X of the base 210X. The structure and connection relationship of one of the moving mechanisms 300X are described in detail below:

[0309] As shown in Figures 59 and 61, in this embodiment, the mounting rod 320X passes approximately through the middle of the mounting cavity 221X of the mounting member 220X. Both ends of the mounting rod 320X extend outwards towards the base 210X, specifically towards the front and rear sides of the base 210X in this embodiment. That is, the length of the mounting rod 320X is greater than the maximum width of the mounting member 220X in the front-rear direction. In other words, at least a portion of the mounting rod 320X's projection in the top view does not coincide with the projection of the base 210X in the top view. Similar to the fourth embodiment, the two wheel components 310X are mounted to both ends of the mounting rod 320X via their wheel seats 313X. This means that the projections of the two wheel components 310X in the top view do not coincide with the projection of the base 210X in the top view. Specifically, the projections of the wheel components 310X in the top view are located on the front and rear sides of the projection of the base 210X in the top view.

[0310] As shown in Figures 59 and 61, when the wheel assembly 310X is in the working position, it is located below the plane containing the bottom surface 201X of the base 210X; when the wheel assembly 310X is in the folded position, it is located above the plane containing the bottom surface 201X of the base 210X and on the side of the base 210X. Specifically, as shown in Figures 58 and 59, when the wheel assembly 310X is in the working position, the roller 311X is approximately located to the left of the connector 3131X, and the projection of the roller 311X in the top view is located on the front and rear sides of the projection of the base 210X in the top view. Alternatively, the roller 311X is located below the mounting rod 320X. In this working position, the roller 311X in the wheel assembly 310X can move the bearing device 10X by rolling. (See Figures 60 and 61) As shown, when the wheel assembly 310X is in the folded position, the roller 311X is approximately above the connecting member 3131X and is located on both the front and rear sides of the base 210X. Alternatively, the roller 311X is located above the mounting rod 320X. This is equivalent to the wheel assembly 310X folding towards the side of the base assembly 200X, with only the mounting rod 320X and part of the connecting member 3131X contacting a flat surface (such as the surface of the car seat 20X) in both moving mechanisms 300X. This allows the support device 10X to be easily and stably placed on a flat surface such as the car seat 20X.

[0311] In this embodiment, as shown in Figure 59, when the wheel assembly 310X is in the use position, the mounting rod 320X corresponding to the wheel assembly 310X rotates approximately 180 degrees around its own central axis in the S2 direction, which can drive the wheel assembly 310X to switch from the use position to the folded position. As shown in Figure 61, when the wheel assembly 310X is in the folded position, the mounting rod 320X corresponding to the wheel assembly 310X rotates approximately 180 degrees around its own central axis in the opposite direction of the S2 direction, which can drive the wheel assembly 310X to switch from the folded position to the use position. Of course, in other embodiments, the mounting rod 320X can also rotate in the opposite direction. As shown in Figure 59, when the wheel assembly 310X is in the use position, the mounting rod 320X corresponding to the wheel assembly 310X rotates approximately 180 degrees around its own central axis in the opposite direction of S2, which can drive the wheel assembly 310X to switch from the use position to the folded position. As shown in Figure 61, when the wheel assembly 310X is in the folded position, the mounting rod 320X corresponding to the wheel assembly 310X rotates approximately 180 degrees around its own central axis in the S2 direction, which can drive the wheel assembly 310X to switch from the folded position to the use position.

[0312] Furthermore, when the moving mechanism 300X is in the folded state, the mounting rod 320X can engage with the engaging mechanism (not shown in the attached figure) on the moving device, thereby fixing the bearing device 10X to the moving device.

[0313] The bearing device 10X proposed in this embodiment also includes a locking mechanism 400X, a moving part 500X, and a pivoting mechanism 600X. The structure and connection relationship of the locking mechanism 400X, the moving part 500X, and the pivoting mechanism 600X are similar to those in the fourth embodiment, and will not be described in detail here.

[0314] In other embodiments, the two mounting members 220X in this embodiment may also extend along the long side (left-right direction) of the bottom surface 201X of the base 210X, and correspondingly, the two mounting rods 320X also extend along the long side (left-right direction) of the bottom surface 201X of the base 210X.

[0315] Sixth Embodiment

[0316] As shown in Figure 62, the present invention provides a support device 10X in the following embodiment. The support device 10X includes a body assembly 100X, a base assembly 200X, and a moving mechanism 300X. The structure and connection relationship of the body assembly 100X and the base assembly 200X in this embodiment are largely the same as in the fourth embodiment, and will not be described in detail here. The main difference between the support device 10X in this embodiment and the support device 10X in the fourth embodiment lies in the moving mechanism 300X.

[0317] As shown in Figures 62 to 65, similar to the fourth embodiment, this embodiment also has two moving mechanisms 300X, and each moving mechanism 300X also includes a wheel assembly 310X and a mounting rod 320X. The base assembly 200X also includes a base 210X and a mounting member 220X disposed on the bottom surface 201X of the base 210X. The difference from the fourth embodiment is that in this embodiment, the two mounting members 220X extend along the short side direction (front-back direction) of the bottom surface 201X of the base 210X, and correspondingly, the two mounting rods 320X also extend along the short side direction (front-back direction) of the bottom surface 201X of the base 210X. The structure and connection relationship of one of the moving mechanisms 300X are specifically described below as an example:

[0318] As shown in Figures 64 and 65, in this embodiment, the mounting rod 320X passes approximately through the middle of the mounting cavity 221X of the mounting member 220X, and the entire mounting rod 320X is located directly below the base 210X. That is, the length of the mounting rod 320X is less than the maximum width of the mounting member 220X in the front-to-back direction. In other words, the projection of the mounting rod 320X in the top view coincides with the projection of the base 210X in the top view. Similar to the fourth embodiment, the two wheel assemblies 310X are respectively mounted to both ends of the mounting rod 320X via their wheel seats 313X. That is, the projections of the two wheel assemblies 310X in the top view coincide with the projection of the base 210X in the top view.

[0319] Further, as shown in Figures 64 and 65, the bottom surface 201X of the base 210X is provided with receiving grooves 219X. In this embodiment, there are four receiving grooves 219X, which are respectively located at the four apex corners of the bottom surface 201X of the base 210X. The positions of the four receiving grooves 219X correspond to the positions of the four wheel assemblies 310X. In this embodiment, the base 210X has a larger thickness than the base 210X in the fourth and fifth embodiments. This design is also to facilitate the creation of the receiving grooves 219X.

[0320] As shown in Figures 64 and 67, when the wheel assembly 310X is in the use position, the roller 311X is located below the bottom surface 201X of the base 210X; when the wheel assembly 310X is in the folded position, the roller 311X is located above the bottom surface 201X of the base 210X and is stored in the receiving groove 219X. Specifically, as shown in Figures 63 to 65, when the wheel assembly 310X is in the use position, the roller 311X is approximately located directly below the connector 3131X, and the projection of the roller 311X in the top view direction coincides with the projection of the base 210X in the top view direction. Alternatively, the roller 311X is located below the mounting rod 320X. The roller 311X in the wheel assembly 310X in this use position can move the bearing device 10X by rolling. As shown in Figures 66 to 68, when the wheel assembly 310X is in the folded position, the roller 311X is approximately above the connector 3131X. The roller 311X is located within the receiving groove 219X of the base 210X. Alternatively, the roller 311X is located above the mounting rod 320X. At this point, it is equivalent to the wheel assembly 310X folding inwards towards the base assembly 200X, and only the mounting rod 320X and part of the connector 3131X of both moving mechanisms 300X are in contact with a plane (such as the plane of the car seat 20X). This allows the support device 10X to be stably placed on a plane such as the car seat 20X, as shown in Figure 69.

[0321] In this embodiment, as shown in Figure 65, when the wheel assembly 310X is in the working position, the mounting rod 320X corresponding to the wheel assembly 310X rotates approximately 180 degrees around its own central axis in the S3 direction, which can drive the wheel assembly 310X to switch from the working position to the folded position. The roller 311X of the wheel assembly 310X is located in the corresponding receiving groove 219X. As shown in Figure 67, when the wheel assembly 310X is in the folded position, the mounting rod 320X corresponding to the wheel assembly 310X rotates approximately 180 degrees around its own central axis in the opposite direction of the S3 direction, which can drive the wheel assembly 310X to switch from the folded position to the working position. The roller 311X of the wheel assembly 310X moves out of the corresponding receiving groove 219X. The S3 direction in this embodiment is approximately the same as the S2 direction in the fifth embodiment.

[0322] In this embodiment, as shown in FIG65, since the receiving groove 219X is approximately located on the opposite inner side of the two corresponding mounting rods 320X, that is, the receiving groove 219X is approximately located on the side of the corresponding mounting rod 320X closer to the other mounting rod 320X, after the mounting rod 320X rotates about 180 degrees around its own central axis in the S3 direction, the wheel assembly 310X connected to it can rotate to the folded position, and the roller 311X is just located in the corresponding receiving groove 219X.

[0323] In some embodiments, when the receiving groove 219X is approximately located on the opposite side of the corresponding mounting rod 320X, i.e., the receiving groove 219X is approximately located on the side of the corresponding mounting rod 320X away from the other mounting rod 320X, then the mounting rod 320X should rotate approximately 180 degrees around its own central axis in the opposite direction of S3 before the wheel assembly 310X connected to it can rotate from the working position to the folded position, with the roller 311X just inside the corresponding receiving groove 219X. Similarly, the mounting rod 320X should rotate approximately 180 degrees around its own central axis in the S3 direction before the wheel assembly 310X connected to it can rotate from the folded position to the working position, with the roller 311X moving out of the receiving groove 219X.

[0324] In other embodiments, the receiving groove 219X can also be configured as a larger groove-shaped structure. By adjusting the position of the mounting member 220X so that the mounting rod 320X passes through approximately the center of the groove opening of the receiving groove 219X, when the wheel assembly 310X is switched from the used position to the folded position, it can rotate approximately 180 degrees around its own central axis in the S3 direction via the mounting rod 320X, or it can rotate approximately 180 degrees around its own central axis in the opposite direction of the S3 direction. Similarly, when the wheel assembly 310X is switched from the folded position to the used position, it can rotate approximately 180 degrees around its own central axis in the opposite direction of the S3 direction via the mounting rod 320X, or it can rotate approximately 180 degrees around its own central axis in the S3 direction.

[0325] Furthermore, when the moving mechanism 300X is in the folded state, the mounting rod 320X can engage with the engaging mechanism (not shown in the attached figure) on the moving device, thereby fixing the bearing device 10X to the moving device.

[0326] The bearing device 10X proposed in this embodiment also includes a locking mechanism 400X, a moving part 500X, and a pivoting mechanism 600X.
