[0040] In the related prior art, the use of vehicles is convenient for users to use outdoors or when traveling, which can effectively reduce the burden on users and is particularly suitable for occasions such as long-term walking, shopping, camping, picnics or travel. However, in the above scenarios, the existing vehicles have problems such as inconvenient placement and retrieval of items and difficulty in entering and exiting the vehicles.

[0041] The present invention provides a vehicle, which may be a cart or a trailer, and which can be used to carry people or goods. When the vehicle is used to carry goods, it has the advantage of being convenient for placing and taking goods, and when the vehicle is used to carry people, it has the advantage of being easy to enter and exit the vehicle. Figures 1 to 14 , solid arrows indicate spaces or slots.

[0042] See also Figures 1 to 14In one embodiment of the present invention, a vehicle 1 includes a vehicle body 10 and an enclosure assembly 900, wherein the vehicle body 10 includes a bottom assembly 100 and a frame assembly 200 disposed on the bottom assembly 100; the enclosure assembly 900 is switchably disposed on the frame assembly 200 between a first position and a second position; in the first position, an accommodating space 11 is enclosed between the enclosure assembly 900 and the vehicle body 10; in the second position, the enclosure assembly 900 opens the accommodating space 11 so that an opening for entering and exiting the accommodating space 11 is formed on the peripheral side of the vehicle 1.

[0043] The bottom component 100 and the surrounding frame component 200 are enclosed to form a accommodating space 11 for carrying people or objects. The bottom component 100 and the surrounding frame component 200 are the main structure of the carrier 1. In order to facilitate the description of the characteristics of this solution, the bottom component 100 and the surrounding frame component 200 and other necessary components of the carrier 1 are referred to as the carrier body 10. The bottom component 100 and the surrounding frame component 200 can be made of lightweight and high-strength materials, such as aluminum alloy, carbon fiber composite material or high-strength plastic. Such material selection can not only reduce the overall weight of the carrier 1, but also improve its bearing capacity and impact resistance, and adapt to different use environments and load requirements. Among them, the bottom component 100 and the surrounding frame component 200 are connected by multiple rods to form a frame, which is used in combination with a cloth. In this way, the weight of the carrier 1 can be further reduced, and such a setting can also save more volume of the carrier 1 in the storage state. In order to improve portability and storage convenience, the bottom component 100 and the surrounding frame component 200 can be designed with a folding structure. For example, the connecting frame 220 can be connected to the side frame 210 via a hinge, and can be folded into the surrounding frame assembly 200 when not in use, thereby reducing the space occupied by the carrier 1 and facilitating storage and transportation.

[0044] In order to facilitate the user to push the vehicle 1 to move, the vehicle body 10 may further include a push rod assembly 300. In order to enhance the user's experience, especially when the vehicle 1 is used to carry people, the top surface of the accommodating space 11 is open or opened, taking the open setting as an example. For example, during outdoor activities, parents use the vehicle 1 to push their children for a ride. At this time, the top surface is open, which is convenient for the children to appreciate the beautiful scenery outside, and convenient for the children to breathe or blow the wind, so that they have a good experience.

[0045] The vehicle 1 further includes a wheel set 14 , which is disposed at the bottom of the bottom assembly 100 . The main function of the wheel set 14 is to provide mobility so that the vehicle 1 can roll smoothly on various ground surfaces.

[0046] The frame assembly 200 is arranged on the bottom assembly 100, and the enclosure assembly 900 is rotatably connected to the frame assembly 200. The bottom assembly 100, the frame assembly 200 and the enclosure assembly 900 are enclosed to form a receiving space 11. In some embodiments, the bottom assembly 100 and the frame assembly 200 can be integrally formed. In other embodiments, the bottom assembly 100, the frame assembly 200 and the enclosure assembly 900 are usually composed of a rod body, and usually need to be equipped with a cloth for use. The bottom assembly 100 and the frame assembly 200 can also be formed by a thin plate.

[0047] The enclosure assembly 900 is switchably arranged on the frame assembly 200 between a first position and a second position. The enclosure assembly 900 and the frame assembly 200 may be rotationally connected, so that the enclosure assembly 900 can be switched between the first position and the second position by rotation. Alternatively, the enclosure assembly 900 and the frame assembly 200 may be slidingly connected, so that the enclosure assembly 900 can be switched between the first position and the second position by movement. Alternatively, the connection between the enclosure assembly 900 and the frame assembly 200 includes a rotational connection and a sliding connection. For example, the connection points between the enclosure assembly 900 and the frame assembly 200 constitute a parallel four-bar linkage structure.

[0048] The enclosure assembly 900 is in a first position, such as Figures 1 to 3 As shown; enclosure assembly 900 is in a second position, such as Figure 4 As shown, the enclosure assembly 900 can also be suspended at any position between the first position and the second position.

[0049] The technical solution of the present invention is to arrange the enclosure component 900 on the frame component 200, and make the enclosure component 900 switchable between a first position and a second position. In the first position, a storage space 11 is enclosed between the bottom component 100, the frame component 200 and the enclosure component 900; in the second position, the enclosure component 900 opens the storage space 11, and an opening connected to the storage space 11 is formed on the side of the vehicle 1; in this way, when the enclosure component 900 is switched to the second position, an opening connected to the storage space 11 is formed on the side of the vehicle 1, and a user can take or place objects through the side opening, or the user can enter or leave the storage space 11 from the side opening, thereby facilitating the placement and retrieval of objects and facilitating entry and exit of the storage space 11.

[0050] Compared to placing and taking out items from the top opening, the technical solution of the present invention places and takes out items from the side, which can reduce the degree of bending of the user to place and take out items, or reduce the height to which the items need to be lifted, thereby making placing and taking out items more labor-saving and more convenient. Compared to entering and exiting the accommodating space 11 from the top opening, the technical solution of the present invention enters and exits the accommodating space 11 from the side, and the height that the user needs to step over is reduced, thereby making it easier to enter and exit the accommodating space 11.

[0051] For example, see Figure 1 The vehicle 1 includes a vehicle body 10 and an enclosure assembly 900. The enclosure assembly 900 is rotatably connected to the upper portion of the enclosure assembly 900 and can be rotatably switched between a first position and a second position. In the first position, an accommodating space 11 is enclosed between the vehicle body 10 and the enclosure assembly 900. In the second position, the enclosure assembly 900 opens the accommodating space 11, and an opening connected to the accommodating space 11 is formed on the peripheral side of the vehicle 1.

[0052] Regarding the enclosure assembly 900 being rotatably connected to the upper portion of the vehicle body 10, the upper portion may be divided according to the total height of the vehicle body 10, with the midline of the total height of the vehicle body 10 serving as the dividing line, and the portion above the dividing line being the upper portion of the vehicle body 10. Exemplarily, the connection between the enclosure assembly 900 and the vehicle body 10 may be at a position that is one-half, one-third, one-quarter, etc., of the distance from the dividing line, or may be at the maximum distance from the dividing line.

[0053] It should be understood that the enclosure assembly 900 and the enclosure frame assembly 200 are rotatably connected, and the rotatable connection may be a hinge, a bearing connection, a universal joint connection, etc., and it is sufficient to realize that the enclosure assembly 900 can be rotatably switched between the first position and the second position relative to the vehicle body 10. Similarly, the rotatable connection between the two components mentioned below may be a hinge, a bearing connection, a universal joint connection, etc.

[0054] In this embodiment, the enclosure assembly 900 is rotatably connected to the upper part of the frame assembly 200, and the enclosure assembly 900 is rotatably switchable between the first position and the second position. In the first position, a storage space 11 is enclosed between the vehicle body 10 and the enclosure assembly 900; in the second position, the enclosure assembly 900 opens the storage space 11, and an opening connected to the storage space 11 is formed on one side of the vehicle body 10; in this way, when the enclosure assembly 900 is switched to the second position, an opening connected to the storage space 11 is formed on the peripheral side of the vehicle 1, and the user can take or put objects through the side opening, or the user can enter or leave the storage space 11 from the side opening, thereby making it convenient to put and take objects and to enter and exit the storage space 11.

[0055] Compared to placing and taking out items from the top opening, the technical solution of the present invention places and takes out items from the side, which can reduce the degree of bending of the user to place and take out items, or reduce the height to which the items need to be lifted, thereby making placing and taking out items more labor-saving and more convenient. Compared to entering and exiting the accommodating space 11 from the top opening, the technical solution of the present invention enters and exits the accommodating space 11 from the side, and the height that the user needs to step over is low, thereby making it easier to enter and exit the accommodating space 11.

[0056] In one embodiment, the enclosure assembly 900 is rotatably mounted on the frame assembly 200 via a first rotating shaft; when the enclosure assembly 900 rotates from the first position to the second position, the side of the enclosure assembly 900 away from the first rotating shaft moves toward the bottom assembly 100 .

[0057] The enclosure assembly 900 is rotatably mounted on the enclosure frame assembly 200 via a first rotating shaft, that is, the enclosure assembly 900 rotates around an axis. During the rotation of the enclosure assembly 900, the enclosure assembly 900 can be rotated from a first position to a second position.

[0058] In the present embodiment, during the process of the enclosure assembly 900 rotating from the first position to the second position, the side of the enclosure assembly 900 away from the first rotating axis moves in the direction close to the bottom. At this time, the enclosure assembly 900 will not be laid in front of the opening. In this way, the user can take and put things from the front of the opening, or enter and exit from the front of the opening. In this way, it is more convenient for the user to take and put things, and it is more convenient to enter and exit the accommodating space 11.

[0059] In one embodiment, the vehicle body 10 includes a support assembly 800, which is connected between the enclosure assembly 900 and the vehicle body 10. The support assembly 800 can be retracted or folded so that the enclosure assembly 900 can be rotated and switched between a first position and a second position.

[0060] The support assembly 800 is used to provide a support structure between the enclosure assembly 900 and the vehicle body 10, wherein the support assembly 800 may be connected to the bottom assembly 100, or the support assembly 800 is connected to the frame assembly 200; or the support assembly 800 is connected to other structures of the vehicle body 10.

[0061] The support assembly 800 is telescopically arranged, that is, the length of the support assembly 800 between the stop assembly and the vehicle body 10 can be adjusted, for example, a telescopic cylinder assembly, or a rod-connecting rod assembly with manually adjustable telescopic amount.

[0062] The support assembly 800 is foldable, that is, the support assembly 800 is generally composed of at least two connected parts, which can be folded and unfolded within a certain angle range. The foldability of the support assembly 800 forms a dynamic adjustment mechanism between unfolding and folding, so that the enclosure assembly 900 can be converted between different positions as needed. After the support assembly 800 is folded, the angle and position of the enclosure assembly 900 will change, thereby enabling the enclosure assembly 900 to achieve rotation switching from the first position to the second position.

[0063] The retractability or foldability of the support assembly 800 makes the enclosure assembly 900 more flexible, and the position of the enclosure assembly 900 can be adjusted according to different usage scenarios. In the first position, the support assembly 800 is unfolded to support the enclosure assembly 900, providing the enclosure assembly 900 with a connection. In the second position, the support assembly 800 is folded close to the enclosure assembly 900 or the frame assembly 200, so that the enclosure assembly 900 can be rotated and switched between the first position and the second position. Usually, the support assembly 800 also needs to have the ability to fix the enclosure assembly 900 in the first position. Of course, in other embodiments, the support assembly 800 can also be detachably connected to the vehicle body 10. In the first position, the support assembly 800 is installed between the support assembly 800 and the vehicle body 10, and the support assembly 800 is supported between the enclosure assembly 900 and the vehicle body 10, so that the enclosure assembly 900 is fixed in the first position.

[0064] In this embodiment, the support assembly 800 is retractable or foldable, so that the enclosure assembly 900 can be easily switched between the first position and the second position.

[0065] In an exemplary embodiment, Figure 4 and Figure 5 As shown, the support assembly 800 can be folded. In the first position, the support assembly 800 is supported between the enclosure assembly 900 and the vehicle body 10; in the second position, the support assembly 800 is folded close to the enclosure assembly 900 or the support rod 810 is folded close to the frame assembly 200.

[0066] Compared with the telescopic assembly, the storage method of the support assembly 800 in this embodiment is generally more efficient because the foldable part can be folded and folded, thereby reducing the space occupied by the support structure, thereby saving space. The support structure of the telescopic arrangement is relatively complex, and the telescopic process may involve multiple connecting parts. As time goes by, the connecting parts may become loose or worn, affecting their stability. The folding design helps to improve the robustness of the structure by reducing the number of moving parts.

[0067] In one embodiment, see Figures 5 to 8 The support assembly 800 includes a sliding member 820 and a support rod 810, the support rod 810 has two opposite ends, and the first end of the support rod 810 is rotatably connected to the sliding member 820; the sliding member 820 is slidably disposed on the enclosure assembly 900, and the second end of the support rod 810 is rotatably connected to the frame assembly 200; or, the sliding member 820 is slidably disposed on the frame assembly 200, and the second end of the support rod 810 is rotatably connected to the enclosure assembly 900.

[0068] The sliding member 820 is generally a component that can slide on the enclosure assembly 900 or the enclosure frame assembly 200. It adjusts the position of the support rod 810 by sliding. The sliding member 820 enables the support rod 810 to adjust the angle or position as needed, thereby realizing flexible adjustment of the enclosure assembly 900. The sliding member 820 may be connected to the enclosure assembly 900 or the enclosure frame assembly 200 through a slide rail, a slide groove or other sliding connection device. In some embodiments, the sliding member 820 and the support rod 810 are integrally formed.

[0069] The support rod 810 has two opposite ends, the first end is rotatably connected to the sliding member 820, that is, the support rod 810 can rotate relative to the connection of the sliding member 820, and the second end of the support rod 810 is connected to the enclosure assembly 900 or the enclosure frame assembly 200. For example:

[0070] Embodiment 1: When the sliding member 820 is slidably disposed on the enclosure assembly 900, the sliding member 820 is connected to the enclosure assembly 900, that is, the first end of the support rod 810 is rotatably connected to the sliding member 820, and the second end is rotatably connected to the frame assembly 200. In this way, the first end of the support rod 810 is connected to the sliding member 820 by rotation, and the support rod 810 can rotate relative to the sliding member 820. Since the sliding member 820 can slide on the enclosure assembly 900, the support rod 810 can adjust the position of the enclosure assembly 900 as the sliding member 820 slides. By adjusting the position of the sliding member 820, the angle or position between the support rod 810 and the enclosure assembly 900 can be changed, thereby realizing adjustable support of the enclosure assembly 900, or switching the enclosure assembly 900 between the first position and the second position.

[0071] Embodiment 2: When the sliding member 820 is slidably disposed on the frame assembly 200, the sliding member 820 is connected to the frame assembly 200, that is, the second end of the support rod 810 is rotatably connected to the enclosure assembly 900. In this way, the sliding adjustment function of the sliding member 820 is to adjust the state of the enclosure assembly 900 by changing the position of the frame assembly 200 or the angle of the support rod 810. The support rod 810 can adjust the relative position or angle of the enclosure assembly 900 according to the sliding of the sliding member 820 on the frame assembly 200, thereby realizing adjustable support of the enclosure assembly 900, or switching the enclosure assembly 900 between the first position and the second position.

[0072] In this embodiment, the combination of the sliding member 820 and the support rod 810 can enable the enclosure assembly 900 to rotate and switch between different positions, and can be flexibly adjusted according to needs.

[0073] In one embodiment, see Figure 1The frame assembly 200 includes a pair of side frames 210 arranged opposite to each other and a connecting frame 220 connected to the pair of side frames 210; the enclosure assembly 900 includes a pair of enclosure rods 910 arranged opposite to each other and a connecting rod 920 connected between the pair of enclosure rods 910, the pair of enclosure rods 910 are rotatably installed on the pair of side frames 210 respectively, and the connecting rod 920 is located at one end of the enclosure rod 910 away from the side frame 210; in the pair of enclosure rods 910 and the pair of side frames 210, a support assembly 800 is correspondingly arranged for one enclosure rod 910 and one side frame 210; wherein the sliding member 820 is arranged on the enclosure rod 910, the sliding member 820 can move along the length direction of the enclosure rod 910, and the second end of the support rod 810 is rotatably connected to the side frame 210.

[0074] The frame assembly 200 includes a pair of side frames 210 arranged opposite to each other and a connecting frame 220 connected to the pair of side frames 210, wherein the side frames 210 are used to form the side boundaries of the frame, provide support and fix the structure of the entire frame assembly 200, and they are connected to each other through the connecting frame 220 to form a frame structure, and the connecting frame 220 connects the pair of side frames 210 together, plays a role in supporting and enhancing the stability of the overall frame, and keeps the shape of the frame from being easily deformed. The connecting frame 220 can be a connecting rod or multiple connecting rods.

[0075] The enclosure assembly 900 includes a pair of enclosure rods 910 arranged opposite to each other and a connecting rod 920 connected between the pair of enclosure rods 910. The assembly formed by the pair of enclosure rods 910 and the connecting rod 920 acts as an enclosure. The enclosure rods 910 are rotatably installed on the enclosure frame assembly 200. Through the setting of the connecting rod 920, the enclosure rods 910 maintain a consistent structural distance, which helps to enhance the stability of the enclosure and reduce the separation of the pair of enclosure rods 910 due to external forces. The enclosure rods 910 can rotate within a certain range, so that the enclosure can be opened and closed or adjusted as needed, thereby opening or closing the accommodating space 11.

[0076] The sliding member 820 is movable along the length direction of the surrounding rod 910, so as to realize the adjustment and displacement of the surrounding rod 910. The support rod 810 is rotatably connected to the side frame 210, so that the support assembly 800 can be adjusted at different angles.

[0077] The surrounding rod 910 is rotatably mounted on the side frame 210, and the surrounding rod 910 can be installed at the upper part or the middle part of the side frame 210. In some embodiments, the surrounding rod 910 can also be installed at the lower part of the side frame 210, for example, set on the side of the side frame 210 close to the connecting frame 220.

[0078] Exemplarily, the enclosure rod 910 is rotatably installed on the upper part of the side frame 210. The upper part can be divided according to the total height of the side frame 210, with the median line of the total height of the side frame 210 as the dividing line. The area above the dividing line is the upper part of the vehicle body 10. Exemplarily, the connection between the enclosure assembly 900 and the vehicle body 10 can be at a position that is one-half, one-third, or one-quarter of the distance from the dividing line, or it can be at the maximum distance from the dividing line.

[0079] In this embodiment, the enclosure rod 910 is rotatably installed on the upper part of the side frame 210. When the enclosure assembly 900 is rotated from the first position to the second position, the side where the connecting rod 920 is located moves toward the direction of the bottom assembly 100. At this time, a pair of enclosure rods 910 are folded on the side frame 210, and the connecting rod 920 is folded on the bottom assembly 100. In this way, the enclosure assembly 900 will not be laid in front of the opening. In this way, the user can take and put things from the front of the opening, or enter and exit from the front of the opening. In this way, it is more convenient for the user to take and put things, and it is more convenient to enter and exit the accommodating space 11.

[0080] In one embodiment, the side frame 210 includes a first side bar 211, a second side bar 212 and a third side bar 213. The first ends of the first side bar 211 and the third side bar 213 are respectively connected to the bottom assembly 100, and the second ends of the first side bar 211 and the third side bar 213 are respectively connected to the second side bar 212; the first side bar 211 is tilted relative to the bottom assembly 100, and the second end of the support rod 810 is rotatably connected to the first side bar 211; the second side bar 212 is located at the top of the side frame 210. The second side rod 212 is extended in the horizontal direction, and the second side rod 212 has a relative front end and a rear end. The surrounding rod 910 is rotatably installed on the front end of the second side rod 212, and the connecting frame 220 is connected to the rear end; in the first position, the surrounding rod 910 is extended along the length direction of the second side rod 212, and the support rod 810, the surrounding rod 910 and the first side rod 211 form a triangular structure; in the second position, the support rod 810 is folded between the first side rod 211 and the surrounding rod 910.

[0081] The first side bar 211, the second side bar 212 and the third side bar 213 constitute the skeleton structure of the side frame 210. The first side bar 211 and the third side bar 213 are connected to the bottom assembly 100 and form the support base of the side frame 210; the second side bar 212 is located at the top of the side frame 210 and extends in the horizontal direction to connect and support other components of the frame; the first end of the first side bar 211 and the third side bar 213 is connected to the bottom assembly 100, and the second end is connected to the second side bar 212. The connection between the first side bar 211 and the third side bar 213 can be a rotating connection, a fixed connection, or a detachable connection, or the first side bar 211 can be telescopically arranged, as long as it can support the structure of the side frame 210.

[0082] Preferably, the first ends of the first side rod 211 and the third side rod 213 are rotatably connected to the bottom assembly 100, the first side rod 211, the second side rod 212 and the third side rod 213 are rotatably connected in sequence, and the third side rod 213 is retractable or foldable (e.g. Figures 12 to 14 ), so that the side frame 210 can be folded, which can further improve the folding rate of the carrier 1 and make the height of the carrier 1 smaller after folding.

[0083] The enclosure rod 910 is rotatably mounted on the front end of the second side rod 212, that is, the enclosure rod 910 is mounted on the top of the side frame 210, and the installation position of the enclosure rod 910 needs to enable it to rotate between the first position and the second position. The connecting frame 220 is connected to the rear end of the second side rod 212, and the connecting frame 220 forms a complete enclosure structure through the connection with the rear end of the second side rod 212, so that there is a firm connection between the enclosure rod 910 and the side frame 210. The rotatable connection of the support rod 810 on the first side rod 211 can provide appropriate support force under different usage requirements to ensure the stability of the enclosure structure.

[0084] Thus, in this embodiment, the enclosure assembly 900 has two main structural changes in position states: the first position (triangular structure): in this position, the enclosure rod 910, the support rod 810 and the first side rod 211 form a stable triangular structure, which is very stable and can effectively disperse external forces to ensure that the enclosure assembly 900 can remain stable and strong in this state. The second position (folded state): in the second position, the support rod 810 is folded between the first side rod 211 and the enclosure rod 910, and the enclosure assembly 900 can be compactly stored when not in use, which is convenient for storage and transportation.

[0085] In the technical solution of this embodiment, when in the first position, the enclosure assembly 900 has good structural stability, and at this time, a closed accommodation space 11 is formed with at least the bottom and each side surface, which can carry people and objects; while in the second position, the support rod 810 can be folded between the enclosure rod 910 and the first side rod 211, forming an opening on the front side of the vehicle 1, and the user can put objects in and take out objects, and enter and exit the accommodation space 11, so that the entire enclosure assembly 900 can greatly reduce the occupied space, and is convenient for storage and transportation. This design allows the enclosure assembly 900 to have both stability and convenience for transportation and storage, and has the ability to flexibly adapt to different occasions.

[0086] In order to enhance the stability of the surrounding frame assembly 200 in the unfolded state, a locking mechanism may be provided at the rotational connection of the first side bar 211, the second side bar 212, and the third side bar 213. For example, by providing a spring pin lock or a knob locking device 500, when the surrounding frame assembly 200 is unfolded, the connection between each side bar can be firmly locked to prevent the side bar from loosening or folding during use.

[0087] In order to achieve compact storage of the surrounding frame assembly 200 when folded and prevent damage caused by excessive folding, a folding limit structure can be provided at the rotation connection of the side rods. The limit structure can be a limit groove or a limit pin. When the side rods are in a folded state, the limit structure automatically limits the folding angle thereof, so that the side rods can be folded tightly together, thereby reducing the occupied space.

[0088] In order to improve the convenience of operation, a quick release structure can be provided at the connection of the side rods, allowing the user to quickly fold or unfold the frame assembly 200 when not in use. For example, by adopting a push-type buckle or a push-pull locking device, the user can easily operate the unfolding and folding of the side rods without additional tools.

[0089] In one embodiment, a sliding support 830 is provided on the surrounding rod 910 , and the sliding support 830 is extended along the length direction of the surrounding rod 910 ; the sliding member 820 is sleeved on the sliding support 830 , and the sliding member 820 can be moved along the length direction of the sliding support 830 .

[0090] The sliding support member 830 usually serves as a track for the sliding member 820. The function of the sliding support member 830 is to provide support for the sliding member 820 and limit its range of motion on the surrounding rod 910. The sliding support member 830 is installed on the surrounding rod 910. The sliding support member 830 extends along the length direction of the surrounding rod 910, making the overall structure of the carrier 1 more compact and easier to control the expansion and folding of the support assembly 800.

[0091] The sliding member 820 is generally a sliding sleeve, and the sliding member 820 is sleeved on the sliding support member 830. By being sleeved on the sliding support member 830, the sliding member 820 can move along the length direction of the support member, thereby changing the position or shape of the surrounding rod 910. In other embodiments, the sliding member 820 can also be a sliding block, and the sliding support member 830 is provided with a sliding groove adapted to be slidably connected with the sliding block.

[0092] The technical solution of this embodiment combines the sliding support member 830 with the sliding member 820. The sliding support member 830 serves as a track for the sliding member 820 and can provide stable support and guidance along the length direction of the surrounding rod 910.

[0093] In one embodiment, if Figures 4 to 8 , the sliding support member 830 is arranged on the inner side of the surrounding rod 910. Among them, the inner side of the surrounding rod 910 refers to the side of a pair of surrounding rods 910 that are close to each other. The carrier 1 also needs to be equipped with a cloth cover for use, and the cloth cover is usually used to protect the enclosure assembly 900, or to provide an aesthetic appearance or protective function. At the enclosure frame assembly 200 and the surrounding rod 910 assembly, the cloth cover is usually arranged on the outside, and the sliding support member 830 is arranged on the inner side of the surrounding rod 910, so that the movement trajectory of the sliding member 820 and the setting space of the cloth cover can avoid each other. Placing the sliding support member 830 on the inside reduces the complicated operation of the cloth cover to bypass the sliding support member 830 during the installation process, thereby simplifying the setting process of the cloth cover and improving the aesthetics of the carrier 1.

[0094] In this embodiment, the sliding support member 830 is arranged on the inner side of the enclosure rod 910, which can avoid direct contact between the cloth cover and the sliding support member 830, thereby protecting the cloth cover from wear and tear, and secondly, improving the neatness and beauty of the enclosure appearance; in addition, the installation and covering of the cloth cover becomes easier, reducing the complexity of the installation process.

[0095] In one embodiment, the sliding member 820 is provided with a locking groove 821, and the carrier body 10 includes a locking device 500, and the locking device 500 includes a locking assembly 510 and an unlocking assembly 520, and the locking assembly 510 is movably switchably arranged on the enclosure rod 910 between a locking position and an unlocking position; the unlocking assembly 520 is drivingly connected to the locking assembly 510; when in the locked position, the locking assembly 510 is located in the locking groove 821 to lock the sliding member 820 to the sliding support member 830, so that the enclosure assembly 900 is fixed in the first position; during the process of switching the locking assembly 510 from the locked position to the unlocked position, the unlocking assembly 520 drives the locking assembly 510 to move toward the unlocked position so that the locking assembly 510 is disengaged from the locking groove 821; when in the unlocked position, the locking assembly 510 is disengaged from the locking groove 821, and the sliding member 820 can slide along the sliding support member 830, so that the enclosure assembly 900 can be rotated and switched between the first position and the second position.

[0096] The locking assembly 510, when in the locked position, is located in the locking groove 821 of the sliding member 820, fixing the sliding member 820 on the sliding support member 830, thereby fixing the enclosure assembly 900 in the first position. The function of the locking assembly 510 is to prevent the sliding member 820 from moving along the sliding support member 830, so that the position of the enclosure assembly 900 does not change during use, and the enclosure assembly 900 is not easy to open the side opening during the operation of the carrier 1, thereby reducing the falling of objects carried from the accommodating space 11, etc.

[0097] The unlocking assembly 520 is drivingly connected to the locking assembly 510. When the locking assembly 510 switches from the locked position to the unlocked position, the unlocking assembly 520 drives the movement of the locking assembly 510 so that the locking assembly 510 is disengaged from the locking groove 821. The unlocking assembly 520 can be arranged on the connecting rod 920 of the enclosure assembly 900, and of course, can also be arranged on a pair of enclosure rods 910 respectively.

[0098] The locking device 500 may be a mechanical locking device 500, or an electromagnetic locking device 500 or a pneumatic locking device 500, or a locking device 500 with a traction rope, which is not specifically limited here. In order to meet the needs of different positions, the locking device 500 may have a multi-level locking function, that is, multiple locking positions are provided at different angles of rotation of the enclosure assembly 900, and the multiple positions are between the first position and the second position. For example, the enclosure rod 910 can be locked at multiple angles such as 30°, 45°, 60° or 90°. The first position and the second position mentioned above are the enclosure assembly 900 that can be understood as the extreme positions. In this way, the user can flexibly adjust the angle of the enclosure rod 910 and lock it according to different usage scenarios (such as placing babies, putting things in and taking things out, or other passengers who can get on and off independently), which increases the convenience of the product.

[0099] The locked position refers to the position of the locking assembly 510, which is located in the locking groove 821, the sliding member 820 is locked, and the position of the enclosure assembly 900 is fixed. At this time, the enclosure cannot be moved at will and can be maintained at the current first position. The unlocked position refers to the position of the locking assembly 510. At this time, when the locking assembly 510 is out of the locking groove 821, the sliding member 820 can slide along the sliding support member 830, so that the enclosure assembly 900 can switch or rotate between the first position and the second position.

[0100] When the position of the enclosure assembly 900 needs to be adjusted, the user can switch the position of the locking assembly 510 by operating the unlocking assembly 520. In the locked state, the locking assembly 510 is located in the locking groove 821, the sliding member 820 is fixed on the sliding support member 830, and the enclosure assembly 900 is in the first position and cannot be freely moved or adjusted. When the position needs to be adjusted, the unlocking assembly 520 is triggered or operated, so that the unlocking assembly 520 drives the locking assembly 510 to move to the unlocking position, so that the locking assembly 510 is separated from the locking groove 821. At this time, the sliding member 820 is no longer locked and can slide freely along the sliding support member 830. Adjust the position of the enclosure assembly 900. Once the locking assembly 510 is separated from the locking groove 821, the sliding member 820 can slide freely on the sliding support member 830, and the enclosure assembly 900 can move between the first position and the second position. After adjusting the position of the enclosure, the user can manually or automatically move the locking assembly 510 to the locking position again, lock the sliding member 820, and fix the enclosure assembly 900 in the first position.

[0101] In this embodiment, the setting of the locking assembly 510 prevents the enclosure assembly 900 from moving at will, thereby maintaining stability. Especially when the enclosure position needs to be fixed for a long time, the locking device 500 provides reliable protection to prevent the enclosure assembly 900 from unnecessary displacement due to external interference.

[0102] In an exemplary embodiment, see Figure 1 , Figures 5 to 7 The unlocking assembly 520 includes an operating member 521 and an unlocking member 522. The operating member 521 is arranged on the connecting rod 920. The two unlocking members 522 are respectively arranged on a pair of surrounding rods 910. The operating member 521 and the two unlocking members 522 are respectively connected by a traction rope. The unlocking member 522 is provided with an unlocking groove 522a, and the unlocking groove 522a is arranged toward the locking assembly 510. The locking assembly 510 includes a mounting seat 511 and a locking member 512 arranged on the mounting seat 511. The locking member 512 is provided with a first clamping portion 513 and a second clamping portion 514. In the locked position When the locking assembly 510 is switched from the locked position to the unlocked position, the user can control the unlocking member 522 to move toward the locking assembly 510 by pressing or sliding the operating member 521, so that the second locking member 514 is locked into the unlocking slot 522a and the first locking member 513 slides out of the locking slot 821; when in the unlocked position, the first locking member 513 is disengaged from the locking slot 821 and the second locking member 514 is locked into the unlocking slot 522a.

[0103] The locking assembly 510 includes a mounting seat 511 and a locking member 512 disposed on the mounting seat 511. The locking member 512 includes two clamping parts. When the first clamping part 513 is in the locked state, the first clamping part 513 is clamped into the locking groove 821 on the connecting member to fix the locking assembly 510 in the locked position, so that the enclosure assembly 900 is fixed in the current position; the second clamping part 514 cooperates with the unlocking groove 522a to play the role of unlocking. When the locking member 512 switches from the locked state to the unlocked state, the second clamping part 514 is clamped into the unlocking groove 522a.

[0104] The unlocking assembly 520 includes an operating member 521 and an unlocking member 522. The operating member 521 is disposed on the connecting rod 920. As a component controlled by the user, the user can control the action of the unlocking member 522 by pressing or sliding the operating member 521. The design of the operating member 521 should ensure that the user can easily reach and operate it. It is usually a handle, button or slider. The unlocking member 522 is provided with an unlocking groove 522a, which faces the locking assembly 510. The function of the unlocking groove 522a is to cooperate with the second clamping portion 514 in the locking assembly 510. The unlocking member 522 is connected to the operating member 521 by a traction rope. The traction rope serves as a transmission tool to transmit the action of the operating member 521 to the unlocking member 522. When the user operates the operating member 521, the traction rope causes the unlocking member 522 to move toward the locking assembly 510, so that the locking assembly 510 switches the state of the locking assembly 510.

[0105] In this embodiment, locking and unlocking are achieved through the combination of the operating member 521, the unlocking member 522, the traction rope and the snap-on mechanism, so that the enclosure assembly 900 can be stably switched between different positions. The user can easily unlock or lock the enclosure assembly 900 by simply pressing a button or sliding a slider.

[0106] In one embodiment, the vehicle body 10 also includes a push rod assembly 300, which is arranged on the side of the frame assembly 120 away from the enclosure assembly 900; the push rod assembly 300 includes a first push rod 310, a second push rod 320 and a third push rod 330 connected in sequence, the first push rod 310 and the third push rod 330 are arranged side by side, and the first push rod 310 and the third push rod 330 are respectively rotatably connected to the frame assembly 120, so that the push rod assembly 300 has a first usage state and a second usage state.

[0107] In this embodiment, the vehicle body 10 further includes a push rod assembly 300. The push rod assembly 300 is located on the side of the frame assembly 120 away from the enclosure assembly 900, facilitating operation and pushing of the vehicle 1. The push rod assembly 300 includes a first push rod 310, a second push rod 320, and a third push rod 330 connected in sequence. The first push rod 310 and the third push rod 330 are arranged side by side and are respectively rotatably connected to the frame assembly 120 through hinges or rotating shafts. In this way, the push rod assembly 300 can achieve the conversion between two states under different usage requirements: the first usage state is the push rod extended state for pushing the vehicle; the second usage state is the push rod folded state for convenient storage and transportation.

[0108] It should be understood that the first push rod 310 and the third push rod 330 are arranged side by side, that is to say, the first push rod 310 and the third push rod 330 are parallel or nearly parallel, and the second push rod 320 is connected between the first push rod 310 and the third push rod 330, so that the overall push rod assembly 300 is arranged in an approximately "C" shape. In this way, the first push rod 310 and the third push rod 330 are arranged side by side, forming two main supporting structures of the trolley, which can disperse the force and increase the overall stability of the trolley. The "C" - shaped design of the push rod assembly 300 makes the operation of the push rod more ergonomic. When the user pushes and pulls, a larger thrust angle and operation space can be obtained, making the vehicle 1 more flexible and labor - saving when turning and moving.

[0109] To improve the operation stability of the push rod assembly 300, a folding locking mechanism can be equipped at the rotational connection of the push rod and the frame assembly 120. This mechanism can adopt a spring pin, a knob locking device, or a cable locking device, so that in the first usage state, the push rod can be firmly extended and fixed in a proper position, avoiding accidental folding of the push rod during use. When the push rod assembly 300 is not in use, the push rod can be quickly folded and stored by pressing or rotating to release the locking device.

[0110] Furthermore, to enhance the comfort of operation, an anti - slip grip can be equipped at the top of the push rod. The grip can be made of soft rubber or silicone material, and the surface is designed with concave - convex patterns or an anti - slip coating, so that the hand will not slip when the user pushes the vehicle, improving the operation safety and comfort.

[0111] During the folding process of the push rod, a limiting device can be set to prevent over - folding and damage to the push rod. The limiting device can adopt a mechanical limiting groove or a locking pin. When the push rod reaches the set folding angle, it automatically limits further folding, so that the push rod can be compactly stored after folding while avoiding damage to the structure.

[0112] The push rod assembly 300 can be designed with a folding and automatic pop - up function. Through a spring or pneumatic structure, the user only needs to press a button, and the push rod can automatically pop up from the folded state to the extended state, improving the operation convenience.

[0113] In one embodiment, the vehicle 1 further includes a tow bar assembly 400, which is movably switchably disposed at the bottom of the vehicle body 10 between a third position and a fourth position; in the third position, the tow bar assembly 400 is accommodated in the vehicle body 10; in the fourth position, at least a portion of the tow bar assembly 400 extends out of the vehicle body 10.

[0114] See also Figure 1 , Figures 8 to 11 In this embodiment, the vehicle 1 includes a tow bar assembly 400, which can be moved and switched between a third position and a fourth position. The tow bar assembly 400 is designed to be usable in different working states, providing a flexible operation mode for the user.

[0115] In the third position, the tow bar assembly 400 is completely accommodated in the vehicle body 10. This accommodated state is intended to reduce the impact of the tow bar assembly 400 on the appearance and aerodynamic performance of the vehicle 1, especially when the vehicle 1 is in a high-speed driving state, it can effectively reduce air resistance and improve the driving stability and efficiency of the vehicle 1. In addition, the tow bar assembly 400 is accommodated in the vehicle body 10, which can also prevent the assembly from being damaged by the external environment in a non-working state, such as collision or scratching, thereby extending the service life of the tow bar assembly 400.

[0116] In the fourth position, at least a portion of the tow bar assembly 400 extends out of the vehicle body 10 to perform specific operation tasks, such as providing a towing function, support, or connection with other equipment. At this time, the tow bar assembly 400 can be fixed in the fourth position by a locking mechanism to ensure its stability and reliability during operation.
