[0062] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0064] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0065] The tops of current vehicles, such as baby strollers, outdoor trailers, etc., especially outdoor trailers, cannot be folded separately, and the height of the storage area is fixed. Therefore, when children or pets want to enter the storage area of ​​the vehicle, they need to climb over the top of the vehicle with a higher height, which makes it less convenient for children or pets to get on and off the vehicle.

[0066] The present invention provides a frame 1. Specifically, the frame 1 can be a frame 1 of a baby carriage, a frame 1 of a pushcart, a frame 1 of a trailer, etc., which is not limited here. Figure 1 A three-dimensional schematic diagram of an embodiment (support position) of a carrier 100 provided by the present invention; Figure 2 for Figure 1 A front view of the vehicle 100; Figure 3 for Figure 1 A three-dimensional schematic diagram of the vehicle 100 in the avoidance position; Figure 4 for Figure 3 A front view of the vehicle 100; Figure 5 for Figure 3 A three-dimensional schematic diagram of the carrier 100 when it starts to fold; Figure 6 for Figure 3 A front view of the carrier 100 during folding; Figure 7 for Figure 3 A three-dimensional schematic diagram of the carrier 100 when it is initially folded; Figure 8 for Figure 7 A front view of the vehicle 100; Fig. 9 for Figure 3 A three-dimensional schematic diagram of the carrier 100 when it is folded; Fig.10 for Fig. 9 For a front view of the vehicle 100, see Figures 1 to 4 In one embodiment of the present invention, the frame 1 includes a base 11 and a side enclosure structure 2, the base 11 has a receiving area 12; the side enclosure structure 2 is arranged along the periphery of the receiving area 12, and has at least a supporting position supported above the base 11, the side enclosure structure 2 includes a avoidance member 21, when in the supporting position, the side enclosure structure 2 is upright and supported on the base 11, the avoidance member is blocked on one side of the side enclosure structure 2, closing the receiving area 12, the side enclosure structure 2 also has a avoidance position, when in the avoidance position, the avoidance member 21 moves to a position relative to other parts of the side enclosure structure 2, forming an opening on one side of the receiving area 12.

[0067] In the technical solution of the present invention, the side enclosure structure 2 has a supporting position and an avoiding position. When the user needs to use the carrier 100 on a daily basis, the side enclosure structure 2 is in the supporting position, thereby blocking the surrounding side of the accommodating area 12 of the base 11. When children or pets need to get on and off the carrier 100, the side enclosure structure 2 is converted into the avoiding position, and the avoiding member 21 moves relative to other parts of the side enclosure structure 2. Thus, through the movement of the avoiding member 21, an opening is formed on one side of the accommodating area 12, so that children or pets do not have to climb over the side enclosure structure 2, and can directly enter and exit the accommodating area 12 from the opening, thereby improving the convenience of getting on and off the existing carrier 100.

[0068] It should be noted that the specific implementation form of the side enclosure structure 2 is not limited, and can be a combination of multiple enclosure rods, or a combination of multiple enclosure rods and cloth pockets, as long as it can enclose the surrounding side of the accommodating area 12 and limit the position of the objects placed in the accommodating area 12. When the vehicle 100 is a trailer, the side enclosure structure 2 can be set with a top opening, so that the user can take and put the items in the accommodating area 12 from the top opening, or it can be set with a top sealing, so as to better limit the position of the items in the accommodating area 12, etc., which are not limited here.

[0069] When the side enclosure structure 2 is in the supporting position, the position of the avoidance member 21 on the side enclosure structure 2 is not restricted, and it may be located at the top of the side enclosure structure 2, or in the middle of the side enclosure structure 2, etc. There is no limitation here, as long as it is located above the base 11.

[0070] When in the avoidance position, the avoidance member 21 can move relative to other parts of the side enclosure structure 2 in a variety of ways, including upward movement, downward movement, or removal of one or both ends of the avoidance member 21 from the side enclosure structure 2.

[0071] Furthermore, in order to improve the switching of the side enclosure structure 2 between the supporting position and the avoiding position, the avoiding member 21 is movable upward or downward relative to other parts of the side enclosure structure 2, so that it does not need to be disassembled and then installed during switching, thereby improving convenience.

[0072] When the avoidance member 21 moves upward relative to other parts of the side enclosure structure 2, the user needs to overcome the gravity of the avoidance member 21 to make the avoidance member 21 move upward, and usually needs to maintain the avoidance member 21 to prevent it from falling off. When the avoidance member 21 moves downward relative to other parts of the side enclosure structure 2, the avoidance member 21 can be moved downward with the help of gravity, and usually the user's hands are not required to maintain the position of the avoidance member 21, which saves effort and frees the user's hands. Therefore, in a further embodiment, in the avoidance position, the avoidance member 21 moves relative to other parts of the side enclosure structure, moving toward or away from the base 11; in the avoidance position, the avoidance member 21 moves downward relative to other parts of the side enclosure structure 2.

[0073] It can be understood that when the side enclosure structure 2 is in the supporting position and the avoidance member 21 is at the top of the side enclosure structure 2, the avoidance member 21 can move downward to the maximum distance and the opening formed is also larger, thereby further improving the convenience of the carrier 100 moving up and down. Therefore, in one embodiment, the avoidance member 21 is at the top of the side enclosure structure 2, and more specifically, the avoidance member 21 can be a part of the top of the side enclosure structure 2, or it can constitute the entire top of the side enclosure structure 2, which is not limited here.

[0074] It should be emphasized that, when in the avoidance position, the greater the distance that the avoidance member 21 moves downward, the larger the corresponding opening formed, and thus the better the convenience of getting the carrier 100 up and down. Therefore, in a further embodiment, when in the avoidance position, the avoidance member 21 moves downward to be stored in the base 11.

[0075] It should be explained that “the avoidance member 21 is stored in the base 11”, which means that the avoidance member 21 is stored in the base 11 as a whole. For example, the avoidance member 21 and the base 11 are connected by a movable telescopic member, and the movable telescopic member is at least partially located in the base 11. When the movable telescopic member is retracted into the base 11 as a whole, the avoidance member 21 is in contact with the base 11 as a whole, so that the avoidance member 21 is stored in the base 11 as a whole. At this time, the avoidance member 21 is at the lowest height as a whole, and it is more convenient for users to get on and off the carrier 100. Of course, it can also be partially stored in the base 11. For example, please refer to Figure 3The avoidance member 21 has two first end portions 212 extending along the second horizontal direction, and a first main body portion 211 extending along the first horizontal direction. The first end portions 212 are connected to other portions of the top of the side enclosure structure 2. At this time, the length of the first end portions 212 is greater than the distance between the top of the side enclosure structure 2 and the base 11 in the up and down directions, so that the avoidance member 21 can rotate its first main body portion 211 to be in contact with the base 11, so that the avoidance member 21 is at least partially stored in the base 11, etc., which is not limited here.

[0076] It is understandable that the avoidance member 21 cannot remain active all the time, otherwise the opening formed by the downward movement of the avoidance member 21 will always be in an open state. At this time, the items placed in the accommodating area 12 are easy to leave the accommodating area 12 from the opening, affecting the user's experience. Therefore, in a further embodiment, the avoidance member 21 can be connected to other parts of the side surrounding structure 2 or the base 11 so as to be rotatable up and down; the side surrounding structure 2 also includes a first limiting structure, which is arranged between the avoidance member 21 and other parts of the side surrounding structure 2, or between the avoidance member 21 and the base 11. When the avoidance member 21 is in the supporting position, the first limiting structure limits the rotation of the avoidance member 21.

[0077] It should be noted that the lifting and lowering activity requires the operation of the lifting parts, and the whole operation process is relatively cumbersome. Therefore, by adopting the up and down rotation method, it is only necessary to release the rotation restriction of the avoidance member 21, and the avoidance member 21 can rotate under its own gravity to open the opening, and the whole operation is relatively simple.

[0078] The avoidance member 21 can be connected to other parts of the side enclosure structure 2 or the base 11 in a rotatable manner, and can be as follows: Figure 3 The connection with the top of the side surrounding structure 2 shown in the figure can also be connected with the base 11 for vertical rotation, for example, Figure 3 The first end portion 212 is directly rotatably connected to the base 11, and may also be connected to the middle portion of the side enclosure structure 2, etc., which is not limited here.

[0079] The specific implementation form of the first limiting structure is not limited, and can be a locking pin arranged between the avoidance member 21 and other parts of the side enclosure structure 2. For example, a locking hole is provided on the avoidance member 21, and the locking pin can be movably installed in and out of the locking hole to other parts of the side enclosure structure 2. When in the supporting position, the locking pin is located in the locking hole, so that the avoidance member 21 is locked and positioned. When it is necessary to get the carrier 100 up and down, the rotation of the avoidance member 21 is locked and unlocked through the movement of the locking pin. It can also be in the form of an adjusting rod, such as a telescopic rod connected between the base 11 and the avoidance member 21, and the telescopic rod is extended and retracted to adjust the avoidance member 21. The avoidance member 21 is limited in rotation in the up and down directions. When the telescopic rod is extended, the avoidance member 21 rotates upward, and when the telescopic rod is shortened, the avoidance member 21 rotates downward. Of course, a positioning structure is provided in the telescopic rod to position the extension and retraction of the telescopic rod. When the telescopic rod cannot be extended or retracted, the telescopic rod supports the avoidance member 21 to limit the rotation of the avoidance member 21. When the telescopic rod can be extended or retracted, the rotation restriction of the avoidance member 21 is released so that it can move between the avoidance position and the supporting position, thereby opening or closing the opening. Of course, the first limiting structure can be implemented in other forms, such as a sliding rod, etc., which is not limited here.

[0080] In the technical solution of the present embodiment, the avoidance member 21 can be arranged to rotate up and down, so that after the rotation restriction of the avoidance member 21 is released, the avoidance member 21 can rotate under the action of its own gravity to open the opening, and the whole operation is relatively simple. By setting the first limiting structure, when the avoidance member 21 is in the supporting position, the first limiting structure limits the rotation of the avoidance member 21, thereby preventing objects from escaping from the accommodating area 12 from the opening formed by the downward rotation of the avoidance member 21 during daily use of the carrier 100.

[0081] In further embodiments, see Figures 1 to 4 The first limiting structure includes a first support member 22, one end of the first support member 22 is connected to the avoidance member 21, and the other end is connected to other parts of the side surrounding structure 2 or the base 11, and at least one end of the first support member 22 can be slidably adjusted.

[0082] It should be noted that at least one end of the first support member 22 can be slidably adjusted. It can be the end connected to the avoidance member 21 that can be slidably adjusted, or the end connected to other parts of the side enclosure structure 2 or the base 11 that can be slidably adjusted, or both ends of the first support member 22 can be slidably adjusted, which is not limited here.

[0083] The specific implementation form of the sliding adjustment is not limited, and a sliding sleeve may be directly provided. For example, one end of the first support member 22 is connected to the avoidance member 21, and the other end is slidingly connected to the base 11. A sliding sleeve may be provided on the base 11, and the two ends of the first support member 22 are respectively connected to the avoidance member 21 and are rotatably connected to the sliding sleeve, so that under the sliding of the sliding sleeve, the size of the first support member 22 in the vertical direction is changed, thereby pulling the avoidance member 21 to rotate in the vertical direction, and the sliding sleeve may be in the form of a damping sliding sleeve, so that when in the supporting position, the sliding sleeve cannot slide without the action of external force. Of course, a locking member may be provided on the sliding sleeve to lock or unlock the sliding of the sliding sleeve, and so on, which are not limited here. Of course, it can also be in the form of opening a slide groove, for example, opening a slide groove on the avoidance member 21, and one end of the first support member 22 is slidably installed in the slide groove, so that when one end of the first support member 22 slides in the slide groove, the size of the first support member 22 in the up and down direction is changed, thereby pulling the avoidance member 21 to rotate in the up and down direction, etc., which is not limited here.

[0084] In the technical solution of the present embodiment, by allowing at least one end of the first support member 22 to be slidably adjusted, the size of the first support member 22 in the up and down directions is adjustable. When adjusting the size of the first support member 22 in the up and down directions, the avoidance member 21 is pulled to rotate in the up and down directions to allow the avoidance member 21 to move between the supporting position and the avoidance position. Through the sliding adjustment method, the adjustment range is wider and the operation is simpler.

[0085] Also, see Figure 1 In a further embodiment, the accommodating area 12 includes two first side edges arranged opposite to each other in the first horizontal direction, and a third side edge and a fourth side edge arranged opposite to each other in the second horizontal direction; the side enclosure structure 2 includes a first side enclosure component 20, and the first side enclosure component 20 includes two first connecting rods 23 and a avoidance member 21, and the two first connecting rods 23 are arranged corresponding to the two first side edges, and one end is connected to the base 11; the avoidance member 21 is arranged corresponding to the third side edge, and the avoidance member 21 has two first end portions 212 extending along the second horizontal direction, and a first main body portion 211 extending along the first horizontal direction, and the two end portions are arranged corresponding to the two first side edges, and the two first end portions 212 are rotatably connected to the other ends of the two connecting rods.

[0086] It should be noted that, one of the first direction and the second direction corresponds to the width direction of the carrier 100, and the other corresponds to the length direction of the carrier 100. The first direction can be the width direction of the carrier 100 and the second direction can be the length direction of the carrier 100, or the first direction can be the length direction of the carrier 100 and the second direction can be the width direction of the carrier 100. No limitation is made here.

[0087] The two first connecting rods 23 are arranged corresponding to the two first side edges, and one end is connected to the base 11, and the other end is rotatably connected to the two first end portions 212 of the avoidance member 21, so as to support the avoidance member 21. Moreover, the rotation of the two first end portions 212 is supported by the two first connecting rods 23. Compared with the solution of a single first end portion 212, the rotation support points are more and the rotation stability is higher.

[0088] The avoidance member 21 has two first end portions 212 extending along the second horizontal direction, and a first main body portion 211 extending along the first horizontal direction, so that during the rotation of the avoidance member 21, the opening is opened on the third side by the first main body portion 211, and the opening is opened on the two first sides by the two first end portions 212.

[0089] In addition, since the two first end portions 212 are rotatably connected to the other ends of the two first connecting rods 23, the avoidance member 21 as a whole can be located at the top of the side enclosure structure 2 when in the supporting position. Compared with the solution of being rotatably connected to other parts of the side enclosure structure 2 or the base 11, the avoidance member 21 remains in shape. Since the avoidance member 21 as a whole is located at the top of the side enclosure structure 2 when in the supporting position, on the one hand, the first main body portion 211 can move from the top of the side enclosure structure 2 to the bottom of the side enclosure structure 2, with a maximum moving distance. On the other hand, the two first end portions 212 can also be correspondingly rotated downward, thereby forming openings on the two first side edges and the entire third side edge, thereby expanding the range of the opening and making it easier to get on and off the vehicle 100.

[0090] Correspondingly, when the carrier 100 is a trailer or a cart, it will be provided with a tow bar 40 or a push bar. At this time, the tow bar 40 or the push bar is correspondingly arranged on the fourth side so that the tow bar 40 or the push bar and the avoidance member 21 are located on opposite sides in the second direction, so as to prevent the tow bar 40 or the push bar from affecting the user getting on and off the carrier 100.

[0091] At this time, the connection position between the first support member 22 and the avoidance member 21 is not restricted, and can be connected to the first main body 211 or to the first end 212. When connected to the first main body 211, the distance between one end of the first support member 22 and the rotation center of the avoidance member 21 in the first direction is the largest. At this time, the avoidance member 21 can be driven to rotate with the minimum force. As long as the rotation restriction on the avoidance member 21 is released, it can rotate under the action of its own gravity. However, correspondingly, at this time, the angle between the first support member 22 and the avoidance frame will also be very small. When the size change of the first support member 22 in the up and down directions is the same, the range in which the avoidance frame can rotate in the up and down directions is smaller.

[0092] Therefore, in a further embodiment, one end of the first support member 22 is connected to the first end portion 212, and the other end is connected to other parts of the enclosure structure or the base 11, and at least one end of the first support member 22 can be slidably adjusted.

[0093] In the technical solution of this embodiment, since one end of the first support member 22 is connected to the first end portion 212, compared with the solution of being connected to the first main body 211, it is closer to the rotation center of the avoidance member 21, so that when the dimensional change in the up and down directions is the same, the avoidance frame can rotate at a larger angle, and correspondingly, the opening is larger.

[0094] However, at this time, the corresponding driving force for driving the rotation of the avoidance member 21 also needs to be greater. Therefore, in a further embodiment, one end of the first support member 22 is connected to the middle of the first end portion 212 in the first direction. At this time, the rotation range and driving force can be taken into account to enhance the user experience.

[0095] The avoidance member 21 can be a part of the top of the side enclosure structure 2, so that only the top part can be rotated to form an opening, or it can constitute the entire top of the side enclosure structure 2, so that the entire top can be lifted or rotated up and down. When the entire top can be lifted or rotated up and down, the blocking effect of the side enclosure structure 2 on the items placed in the accommodating area 12 will be greatly weakened, so that the items can easily escape from the accommodating area 12. Therefore, in a further embodiment, the side enclosure structure 2 includes a second side enclosure assembly 30, and the second side enclosure assembly 30 includes: two second connecting rods 31 and a side enclosure rod 32, the two second connecting rods 31 are arranged corresponding to the two first side edges, and are arranged crosswise with the two first connecting rods 23, one end of the two second connecting rods 31 is connected to the base 11, and the other end extends to the fourth side edge of the accommodating area 12; the side enclosure rod 32 is arranged corresponding to the fourth side edge, and the two ends of the side enclosure rod 32 are connected to the two second connecting rods 31.

[0096] In the technical solution of this embodiment, by setting the second connecting rod 31, the second connecting rod 31 and the first connecting rod 23 are cross-set, so that the second connecting rod 31, the first connecting rod 23 and the base 11 can form a triangle, thereby improving the support stability of the side enclosure structure 2 when it is in the supporting position.

[0097] The other ends of the two second connecting rods 31 extend toward the fourth side of the accommodating area 12 , and their positions at the top of the side enclosure structure 2 are offset from the avoidance member 21 , thereby not interfering with the movement of the avoidance member 21 .

[0098] Correspondingly, the side enclosure rod 32 is arranged corresponding to the fourth side, and the two ends of the side enclosure rod 32 are connected to the two second connecting rods 31, so that the side enclosure rod 32 and the avoidance member 21 are located at the fourth side and the other at the third side. When the avoidance member 21 rotates, the side enclosure rod 32 does not have to rotate accordingly, so that when the side enclosure structure 2 is transformed from the supporting position to the avoidance position, the side enclosure rod 32 can still remain in its original position to enclose the items in the accommodating area 12 and prevent the items in the accommodating area 12 from escaping from the accommodating area 12.

[0099] The other end of the first support member 22 can be connected to other parts of the side enclosure structure 2, for example, it can be directly connected to the first connecting rod 23, or it can be connected to the second connecting rod 31, or it can be connected to the base 11. When connected to the first connecting rod 23 or the base 11, the overall length of the first support member 22 will be made relatively long. For example, when connected to the first connecting rod 23, the first connecting rod 23, the first end portion 212 and the first support member 22 will form a triangle. When in the supporting position, the angle corresponding to the first support member 22 is an obtuse angle, that is, the longest side in the triangle, and its length will be greater than the length of the first end portion 212. When connected to the base 11, the length of the first support member 22 must be greater than or equal to the height of the side enclosure structure 2, and its length is also very large. Once the length of the first support member 22 is large, its strength will be correspondingly small, thereby making the stability of the rotation locking of the avoidance member 21 poor.

[0100] Therefore, one end of the first support member 22 is connected to the first end portion 212, and the other end is connected to the second connecting rod 31. The position where the other end of the first support member 22 is connected to the second connecting rod 31 is located below the intersection of the first connecting rod 23 and the second connecting rod 31, so that the overall length of the first support member 22 can be set to be relatively small. Figure 4 ,from Figure 4 It can be clearly seen that the length of the first support member 22 is much smaller than the length of the first end portion 212 , thereby ensuring the strength of the first support member 22 and improving the stability of the rotation locking of the avoidance member 21 .

[0101] At least one end of the first support member 22 can be slidably adjusted, and can be the end connected to the first end portion 212 that can be slidably adjusted, or can be the end connected to the second connecting rod 31 that can be slidably adjusted. No limitation is made here. In the present embodiment, one end of the first support member 22 is rotatably connected to the first end portion 212, and the other end is connected to the second connecting rod 31, and the other end can be slidably adjusted.

[0102] Correspondingly, the first support member 22 may be provided in one or two forms, and there is no limitation on this. When only one form is provided, when the side enclosure structure 2 is in the supporting position, only one of the two first end portions 212 of the avoidance member 21 is supported by the first support member 22, and the stability is poor. Therefore, in a further embodiment, two first support frames are provided corresponding to the two first end portions 212 of the avoidance member 21.

[0103] In addition, it should be emphasized that the frame 1 as a whole can be non-foldable. In this case, the overall stability of the frame 1 is better, but when stored, it also takes up more space, affecting the user experience. In order to facilitate storage, the frame 1 can be set to be foldable. Therefore, in a further embodiment, the frame 1 has an unfolded state and a folded state. When the frame 1 is in the unfolded state, the side enclosure structure 2 has the supporting position and the avoidance position. When the frame 1 is converted from the unfolded state to the folded state, the side enclosure structure 2 is folded to the base 11, and the avoidance member 21 is folded along with the movement of the side enclosure structure 2. In this way, the side enclosure structure 2 can be folded to the base 11, thereby enabling the frame 1 as a whole to be folded, reducing the occupied space. At the same time, the avoidance member 21 can be set along with the movement of the side enclosure structure 2, so that the avoidance member 21 does not need to be removed from the side enclosure structure 2, making the folding of the frame 1 more convenient.

[0104] When the vehicle frame 1 is in the folded state, only the side surrounding structure 2 may be folded to the base 1 , or the base 11 may also be folded.

[0105] In one embodiment, the avoidance member 21 is rotatably connected to other parts of the side enclosure structure 2, and when the frame 1 is converted from the unfolded state to the folded state, the avoidance member 21 is rotatably folded on one side of the side enclosure structure 2; the avoidance member 21 is rotatably connected to other parts of the side enclosure structure 2, and the side enclosure structure 2 also includes a first support member 22, one end of the first support member 22 is movably connected to the side enclosure structure 2, and the other end is movably connected to the avoidance member 21, and when the side enclosure structure 2 is folded to the base 11, the avoidance member 21 is driven to be folded on one side of the side enclosure structure 2 by the first support member 22.

[0106] In the technical solution of the present embodiment, when the side enclosure structure 2 is switched from the supporting position to the avoiding position, the movement of the first supporting member 22 can drive the avoiding member 21 to rotate relative to other parts of the side enclosure structure 2, thereby canceling the blockage of the accommodating area 12 and forming an opening on one side of the accommodating area 12; and when the frame 1 is switched from the unfolded state to the folded state, the movement of the first supporting member 22 can be driven by the movement of the side enclosure structure 2, and then the movement of the avoiding member 21 can be mobilized by the movement of the first supporting member 22, so that the avoiding member 21 is folded on one side of the side enclosure structure 2, and the side enclosure structure 2 can be folded to the base 11 without disassembling the avoiding member 21.

[0107] It should be noted that the base 11 as a whole can be arranged to be non-foldable. In this case, the overall stability of the base 11 is better. However, when stored, even after the side frame structure 2 is folded to the base 11, the entire frame 1 still needs to occupy more space. In order to facilitate storage, the base 11 can be arranged to be foldable. Therefore, in a further embodiment, the base 11 includes a first bottom bracket 13 and a second bottom bracket 14 which are segmented in the second direction, and the first bottom bracket 13 and the second bottom bracket 14 are rotatably connected; the side frame structure 2 includes a first side frame assembly 20 and a second side frame assembly 30, one end of the first side frame assembly 20 is connected to the second bottom bracket 14, and the other end extends toward the first bottom bracket 13, and one end of the second side frame assembly 30 is connected to the first bottom bracket 13, and the other end extends toward the second bottom bracket 14.

[0108] In the technical solution of this embodiment, when the base 11 is folded, the first bottom bracket 13 and the second bottom bracket 14 are rotated to be close to each other, thereby completing the folding of the base 11; and in the process of the first bottom bracket 12 and the second bottom bracket 14 rotating, the first side frame assembly 20 will follow the movement of the second bottom bracket 14, and the second side frame assembly 30 will follow the movement of the first bottom bracket 13, so that the first side frame assembly 20 and the second side frame assembly 30 will also be close to each other, thereby realizing the common folding of the side frame structure 2 and the base 11, so that the volume of the overall frame 11 in the folded state can be reduced to a lower level, saving storage space.

[0109] The rotating shaft that the first bottom bracket 13 and the second bottom bracket 14 are rotatably connected to each other may extend in the first horizontal direction or in the up-down direction. It is understandable that when the rotating shaft that the first bottom bracket 13 and the second bottom bracket 14 are rotatably connected to each other extends in the up-down direction, when folding, the extension direction of the base 11 is changed from the second horizontal direction to the first horizontal direction. Although the height of the base 11 does not need to be changed during the entire folding process, it only reduces the length of the space occupied by the overall frame 1, and the first side enclosure assembly 20 and the second side enclosure assembly 30 are likely to interfere with each other, making it difficult for the overall frame 1 to be folded to a smaller size. Therefore, in some embodiments, the first bottom bracket 13 and the second bottom bracket 14 are rotatably connected along an axis extending in the first horizontal direction; with such a configuration, when the base 11 needs to be folded, one of the first bottom bracket 13 and the second bottom bracket 14 is pulled upward, and the ends of the two that are close to each other will move upward. At this time, the first side panel assembly 20 and the second side panel assembly 30 follow the movement and move in opposite directions. The first side panel assembly 20 and the second side panel assembly 30 will not interfere with each other, and the volume of the frame 1 can be folded to a smaller size.

[0110] The first side enclosure assembly and the second side enclosure assembly together constitute the side enclosure structure, and the two can be symmetrically arranged or asymmetrically arranged; when symmetrically arranged, the overall stability of the side enclosure structure will be better and it will be more convenient to fold.

[0111] In a further embodiment, the accommodating area 12 includes two first side edges arranged opposite to each other in the first horizontal direction, and a third side edge and a fourth side edge arranged opposite to each other in the second horizontal direction; the first side enclosure assembly 20 includes two first connecting rods 23 and the avoidance member 21, the two first connecting rods 23 are arranged corresponding to the two first side edges, and one end of the two first connecting rods 23 is connected to the second bottom bracket 14, and the other end extends to the third side edge of the accommodating area 12; the second side enclosure assembly 30 includes two second connecting rods 31 and a side enclosure rod 32, the two second connecting rods 31 are arranged corresponding to the two first side edges, and correspond to the two first connecting rods 2 3 are cross-arranged, one end of the two second connecting rods 31 is connected to the first bottom bracket 13, and the other end extends to the fourth side of the accommodating area 12; the side enclosure rod 32 is arranged corresponding to the fourth side, and the two ends of the side enclosure rod 32 are connected to the two second connecting rods 31 accordingly; the first side enclosure assembly 20 includes two first connecting rods 23, the avoidance member 21 and the first supporting member 22, the two first connecting rods 23 are arranged corresponding to the two first sides, and one end is connected to the second bottom bracket 14; the avoidance member 21 is arranged corresponding to the third side, and the avoidance member 21 is rotatably connected to the other end of the two first connecting rods 23.

[0112] There are many specific implementation forms of sliding adjustment, which can be directly provided with a sliding sleeve or provided with a sliding groove. In this embodiment, the first side enclosure assembly 20 further includes a sliding sleeve slidably provided on the second connecting rod 31, one end of the second supporting member 22 is rotatably connected to the axis of the sliding sleeve extending along the first horizontal direction, and the other end is rotatably connected to the axis of the avoiding member 21 extending along the first horizontal direction. When the avoiding member 21 is converted from the supporting position to the avoiding position, the sliding sleeve slides upward, and when the avoiding member 21 is folded to the base 11, the sliding sleeve slides downward along the second connecting rod 31.

[0113] It is understandable that the avoidance member 21 cannot be kept active all the time, otherwise the opening formed by the downward movement of the avoidance member 21 will be kept in an open state. At this time, the items placed in the accommodating area 12 are easy to be separated from the accommodating area 12 from the opening, affecting the user's experience. Therefore, in this embodiment, a locking structure is formed between the sliding sleeve and the first support member 31. When in the supporting position, the locking structure locks the sliding sleeve and the first support member 31, so that the avoidance member 21 is maintained in the supporting position. When the supporting position is switched to the avoidance position, the locking structure is unlocked, so that the sliding sleeve can slide upward on the first support member 31, so as to be in the avoidance position; of course, when the frame 1 needs to be folded, in order to prevent the avoidance member 21 from moving around and affecting the operation, that is, when the frame 1 is switched from the avoidance position to the folded state, the locking structure locks the sliding sleeve and the second support member to limit the avoidance member 21. In this embodiment, the locking structure includes, for example, a locking member disposed on one of the sliding sleeve and the first support rod 31, and a locking hole disposed in the other. In other examples, other existing locking methods may also be used.

[0114] In the technical solution of this embodiment, please refer to Figures 2 to 10 When the frame 1 needs to be folded and stored, first Figure 4 When one of the first bottom bracket 13 and the second bottom bracket 14 is pulled upward, the ends of the two that are close to each other will move upward. At this time, since the first bottom bracket 13 and the second bottom bracket 14 are rotationally connected along an axis extending in the first horizontal direction, the first bottom bracket 13 and the second bottom bracket 14 will rotate relative to each other, and the connection point between the two will also move upward, achieving Figure 5 and Figure 6 In the state of the frame 1, during the upward movement of the connection point, the angle between the first bottom bracket 13 and the second bottom bracket 14 gradually decreases from 180 degrees, and the two are folded, so that the sizes of the two in the first direction will also become smaller.

[0115] At this time, the middle parts of the two first connecting rods 23 and the two second connecting rods 31 are correspondingly rotatably connected, one end of the first connecting rod 23 is rotatably connected to the second bottom bracket 14, and one end of the second connecting rod 31 is rotatably connected to the first bottom bracket 13. When the sizes of the first bottom bracket 13 and the second bottom bracket 14 in the first direction become smaller, the distance between the connection points of the two first connecting rods 23 and the two second connecting rods 31 and the base 11 in the first direction will also become smaller, thereby pulling the first connecting rod 23 and the second connecting rod 31 to be folded, and the size of the entire frame 1 in the first direction is reduced, completing the overall folding and storage of the frame 1.

[0116] It can be understood that before the frame 1 is folded, the child or pet in the accommodating area 12 needs to come down from the opening, that is, the locking structure is unlocked, the avoidance member 21 rotates relative to the frame structure, driving the second support member 22 to move, so that the sliding sleeve slides upward along the first connecting rod 31, and the frame structure is in the avoidance position, such as Figure 4 As shown, the child or pet in the accommodating area 12 comes down from the opening. At this time, the frame 1 can be folded.

[0117] When folding the frame 1, the avoidance member 21 can be rotated first to make the frame structure in the supporting position, and then continue. At this time, the locking structure is in the locking state, and when the frame is converted from the folded state to the unfolded state, the side surrounding structure is in the supporting position.

[0118] In other embodiments, when the frame 1 is folded, the frame structure can be directly folded when it is in the avoidance position. At this time, the locking structure is in the unlocked state, and the avoidance member 21 is in the active state. When the base 11 is lifted upward, the first connecting rod 23 and the second connecting rod 31 are driven to rotate relative to each other and folded. Figure 8 and Figure 7 Then, the sliding sleeve and the first supporting member 31 can slide downward relative to each other, and the avoiding member 21 continues to rotate until the second connecting rod 31 is in contact with each other, so as to achieve Fig. 9 and Fig.10 In this state, the corresponding frame 1 has the smallest size in the first direction, and when stored, the space and volume occupied are correspondingly small. At the same time, the sliding sleeve moves downward to the initial position, so that the locking mechanism is locked. Therefore, when the user unfolds the frame 1 for use again, the side structure is in the supporting position, which is convenient for the user to use; on the other hand, it can prevent the various rods in the frame in the folded state from spreading out, which is convenient for carrying and placing.

[0119] Furthermore, the side enclosure rod 32 may be fixedly connected to the second connecting rod 31 or rotatably connected, which is not limited here. When fixedly connected, the corresponding side enclosure structure 2 has better stability when it is in the supporting position. However, when the frame 1 is folded as a whole, the gap between the side enclosure rod 32 and the second connecting rod 31 is large, resulting in a larger overall size and a larger occupied space when the frame 1 is folded. Therefore, in a further embodiment, the side enclosure rod 32 includes two second end portions 321 and a second main body portion 322, the two second end portions 321 are correspondingly arranged along the two first side edges and extend along the second horizontal direction; the second main body portion 322 is arranged along the fourth side edge, and its two ends are correspondingly connected to the two second end portions 321; the two second end portions 321 are correspondingly rotatably connected to the two second connecting rods 31, and a second limiting structure is arranged at the position corresponding to at least one of the second end portions 321, and the second limiting structure is used to limit the second end portions 321 when the two second end portions 321 are in the unfolded state relative to the two second connecting rods 31 to limit their rotation.

[0120] In the solution of the present embodiment, the two second end portions 321 arranged along the two first side edges can enclose the accommodating area 12 at the two first side edges of the accommodating area 12 to prevent items from escaping from the accommodating area 12, and the second main body portion 322 can enclose the accommodating area 12 at the fourth side edge of the accommodating area 12, further improving the enclosing effect of the side enclosure structure 2 when it is in the supporting position, and the two second end portions 321 are correspondingly rotatably connected to the two second connecting rods 31, so that when the frame 1 is stored and folded, the side enclosure rods 32 can be rotated, thereby reducing the gap between the two, thereby reducing the overall size of the frame 1 when it is folded.

[0121] In addition, a second limiting structure is provided at a position corresponding to at least one of the second end portions 321. The second limiting structure is used to limit the second end portions 321 when the two second end portions 321 are in an unfolded state relative to the two second connecting rods 31, so as to limit the rotation thereof, thereby limiting the relative rotation of the side enclosure rod 32 when the side enclosure structure 2 is in a supporting position.

[0122] Furthermore, the specific implementation form of the second limiting structure is not limited, and it can be in the form of a locking pin, or in the form of a support rod, etc., which is not limited here.

[0123] In a further embodiment, the second limiting structure includes a second support member 33, one end of the second support member 33 is rotatably connected to the second end portion 321, and the other end is rotatably connected to the corresponding first connecting rod 23. In this way, when the two second end portions 321 are in an unfolded state relative to the two second connecting rods 31, and the first connecting rod 23 does not move, the second support member 33 will support the side enclosure rod 32 to limit its rotation. When the frame 1 is folded and stored, the first connecting rod 23 and the second connecting rod 31 rotate relative to each other. At this time, the second support member 33 will also move under the pulling of the first connecting rod 23, thereby pulling the side enclosure rod 32 to rotate in a direction close to the first connecting rod 23. Figure 6 state, move to the adjacent Figure 7 status.

[0124] The present invention also proposes a vehicle 100, which includes a frame 1 as described above. The specific structure of the frame 1 refers to the above embodiment. Since the vehicle 100 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the frame 1 includes a base 11 and a side frame structure 2, and the base 11 has a accommodating area 12; the side frame structure 2 is arranged along the periphery of the accommodating area 12, and has at least a supporting position supported above the base 11. When in the supporting position, the side frame structure 2 stands upright and supports on the base 11. The side frame structure 2 includes an avoidance member 21, and the side frame structure 2 also has an avoidance position. When in the avoidance position, the avoidance member 21 moves downward to a position relative to other parts of the side frame structure 2.

[0125] In the technical solution of the present invention, the side enclosure structure 2 has a supporting position and an avoiding position. When the user needs to use the carrier 100 on a daily basis, the side enclosure structure 2 is in the supporting position, thereby blocking the surrounding side of the accommodating area 12 of the base 11. When children or pets need to get on and off the carrier 100, the side enclosure structure 2 is converted into the avoiding position, and the avoiding member 21 moves downward relative to other parts of the side enclosure structure 2, so that through the movement of the avoiding member 21, a passage for children or pets to enter and exit is formed on the side enclosure structure 2, so that children or pets do not have to climb over the side enclosure structure 2, and can directly enter and exit the accommodating area 12 from the passage, thereby improving the convenience of getting on and off the existing carrier 100.

[0126] Correspondingly, the specific implementation form of the carrier 100 is not limited, and it can be a stroller, a trailer, a cart, etc. In one embodiment, the carrier 100 includes but is not limited to a trailer, and the trailer includes a push rod 40 arranged on the frame 1, and moving wheels arranged on the frame structure 2.

[0127] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
