[0040] In existing technologies, vehicles facilitate user use outdoors or while traveling, effectively reducing the user's burden, and are particularly suitable for long walks, shopping, camping, picnicking, or travel. However, in these scenarios, existing vehicles suffer from inconvenience in placing and retrieving items, as well as difficulties in getting in and out of the vehicle.

[0041] This utility model proposes a carrier, which can be a trolley or a trailer, and can be used to carry both people and goods. When used to carry goods, it has the advantage of being convenient for loading and unloading; when used to carry people, it has the advantage of being easy to enter and exit. For ease of understanding and explanation, the following is attached to the specification of this utility model. Figures 1 to 14 In the diagram, the solid arrow indicates a space or slot.

[0042] Please see Figures 1 to 14In one embodiment of the present invention, the vehicle 1 includes a vehicle body 10 and a enclosure assembly 900. 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 in a first position and a second position. In the first position, the enclosure assembly 900 and the vehicle body 10 enclose an accommodating space 11. 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 periphery of the vehicle 1.

[0043] The bottom component 100 and the frame component 200 enclose a space 11 for carrying people or goods. The bottom component 100 and the frame component 200 are the main structure of the vehicle 1. For ease of explanation, the bottom component 100 and the frame component 200, which constitute the necessary parts of the vehicle 1, are referred to as the vehicle body 10. The bottom component 100 and the frame component 200 can be made of lightweight and high-strength materials, such as aluminum alloy, carbon fiber composite materials, or high-strength plastics. This material selection not only reduces the overall weight of the vehicle 1 but also improves its load-bearing capacity and impact resistance, adapting to different usage environments and load requirements. The bottom component 100 and the frame component 200 are connected by multiple rods to form a frame, which is used with a surrounding fabric. This further reduces the weight of the vehicle 1, and also saves space when the vehicle 1 is folded. To improve portability and storage convenience, the bottom component 100 and the frame component 200 can adopt a folding structure design. For example, the connecting frame 220 can be connected to the side frame 210 via a hinge, and can be folded into the frame assembly 200 when not in use, reducing the space occupied by the vehicle 1 and facilitating storage and transportation.

[0044] To facilitate the user's movement of the vehicle 1, the vehicle body 10 may also include a push rod assembly 300. To enhance the user experience, especially when the vehicle 1 is used for carrying passengers, the top surface of the aforementioned accommodating space 11 is open or has an opening, for example, an open design. For instance, during outdoor activities, when parents use the vehicle 1 to push their children around, an open top allows children to enjoy the scenery and allows for ventilation, resulting in a pleasant user experience.

[0045] The vehicle 1 also includes a wheel set 14, which is located 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 surfaces.

[0046] A frame assembly 200 is disposed on the bottom assembly 100, and a barrier assembly 900 is rotatably connected to the frame assembly 200. The bottom assembly 100, the frame assembly 200, and the barrier assembly 900 enclose and form an accommodating space 11. In some embodiments, the bottom assembly 100 and the frame assembly 200 may be integrally formed. In other embodiments, the bottom assembly 100, the frame assembly 200, and the barrier assembly 900 are typically composed of rods and usually require the support of a protective fabric. The bottom assembly 100 and the frame assembly 200 may also be formed of thin plates.

[0047] The fencing assembly 900 is switchably disposed on the frame assembly 200 in a first position and a second position. The fencing assembly 900 and the frame assembly 200 can be rotatably connected, so that the fencing assembly 900 can switch between the first position and the second position by rotation. Alternatively, the fencing assembly 900 and the frame assembly 200 can be slidably connected, so that the fencing assembly 900 can switch between the first position and the second position by movement. Or, the connection between the fencing assembly 900 and the frame assembly 200 includes a rotatable connection and a slidable connection. For example, the connection points between the fencing assembly 900 and the frame assembly 200 form a parallel four-bar structure.

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

[0049] The technical solution of this utility model involves placing a barrier component 900 on a frame component 200, and allowing the barrier component 900 to be switched between a first position and a second position. In the first position, a receiving space 11 is formed between the bottom component 100, the frame component 200, and the barrier component 900. In the second position, the barrier component 900 opens the receiving space 11, and an opening communicating with the receiving space 11 is formed on the periphery of the carrier 1. Thus, when the barrier component 900 is switched to the second position, an opening communicating with the receiving space 11 is formed on the periphery of the carrier 1. Users can take or put down items through this side opening, or users can enter or leave the receiving space 11 through this side opening, thereby facilitating the taking and putting down of items and facilitating entry and exit from the receiving space 11.

[0050] Compared to placing and retrieving items through the top opening, the present invention allows for placement and retrieval from the side, reducing the bending required and the height at which items need to be raised, making it easier and less strenuous. Furthermore, compared to entering and exiting the storage space 11 through the top opening, the side entry and exit reduces the height the user needs to step over, making entry and exit easier.

[0051] For example, please refer to Figure 1 The vehicle 1 includes a vehicle body 10 and a enclosure assembly 900. The enclosure assembly 900 is rotatably connected to the upper part of the vehicle body 10 and can be rotatably switched between a first position and a second position. In the first position, an accommodating space 11 is formed 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 communicating with the accommodating space 11 is formed on the periphery of the vehicle 1.

[0052] Regarding the enclosure assembly 900 being rotatably connected to the upper part of the vehicle body 10, the upper part can be divided by the total height of the vehicle body 10, with the midline of the total height of the vehicle body 10 as the dividing line. The part above the dividing line is the upper part of the vehicle body 10. For example, the connection point between the enclosure assembly 900 and the vehicle body 10 can be at a position one-half, one-third, or one-quarter away from the dividing line, or it can be at the point where the distance from the dividing line is the greatest.

[0053] It should be understood that the enclosure assembly 900 and the frame assembly 200 are rotatably connected. This rotatable connection can be a hinge, a bearing connection, or a universal joint connection, etc., as long as it allows the enclosure assembly 900 to rotate between a first position and a second position relative to the vehicle body 10. Similarly, the rotatable connection between the two components mentioned below can also be a hinge, a bearing connection, or 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 a first position and a second position. In the first position, a receiving space 11 is formed between the vehicle body 10 and the enclosure assembly 900. In the second position, the enclosure assembly 900 opens the receiving space 11, and an opening communicating with the receiving space 11 is formed on one side of the vehicle body 10. Thus, when the enclosure assembly 900 is switched to the second position, an opening communicating with the receiving space 11 is formed on the periphery of the vehicle 1. The user can take or put down items through this side opening, or the user can enter or leave the receiving space 11 through this side opening, thereby facilitating the taking and putting down of items and facilitating entry and exit from the receiving space 11.

[0055] Compared to placing and retrieving items through the top opening, the present invention allows for placement and retrieval from the side, reducing the bending required and the height at which items need to be raised, making it more effortless and convenient. Furthermore, compared to entering and exiting the storage space 11 through the top opening, the side opening reduces the height the user needs to step over, making entry and exit easier.

[0056] In one embodiment, the enclosure assembly 900 is rotatably mounted on the frame assembly 200 via a first pivot; 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 pivot 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. In other words, the rotation of the enclosure assembly 900 is 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 this embodiment, during the process of the enclosure component 900 rotating from the first position to the second position, the side of the enclosure component 900 away from the first pivot moves along the direction close to the bottom. At this time, the enclosure component 900 will not be placed in front of the opening. In this way, the user can take or put down items from the front of the opening, or enter or exit from the front of the opening. This makes it more convenient for the user to take or put down items and to enter or exit the accommodating space 11.

[0059] In one embodiment, the vehicle body 10 includes a support component 800 connected between the enclosure component 900 and the vehicle body 10. The support component 800 is telescopic or foldable, so that the enclosure component 900 can rotate and switch between a first position and a second position.

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

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

[0062] The support component 800 is foldable, meaning it typically consists of at least two connecting parts that can be folded and unfolded within a certain angle range. This foldability of the support component 800 creates a dynamic adjustment mechanism between unfolding and folding, allowing the fencing component 900 to switch between different positions as needed. When the support component 800 is folded, the angle and position of the fencing component 900 change, enabling it to rotate and switch from a first position to a second position.

[0063] The stretchability or foldability of the support component 800 gives the fencing component 900 greater flexibility, allowing for positional adjustments based on different usage scenarios. In a first position, the support component 800 unfolds to support the fencing component 900, providing a connection. In a second position, the support component 800 folds up against the fencing component 900 or the frame component 200, enabling the fencing component 900 to rotate and switch between the first and second positions. Typically, the support component 800 also needs to have the ability to fix the fencing component 900 in the first position. Alternatively, in other embodiments, the support component 800 can be detachably connected to the vehicle body 10. In the first position, the support component 800 is installed between the fencing component 900 and the vehicle body 10, supporting the fencing component 900 between them, thus fixing the fencing component 900 in the first position.

[0064] In this embodiment, the support component 800 is retractable or foldable, which facilitates the switching of the enclosure component 900 between the first position and the second position.

[0065] In one exemplary embodiment, such as Figure 4 and Figure 5 As shown, the support component 800 is foldable. In the first position, the support component 800 is supported between the enclosure component 900 and the vehicle body 10; in the second position, the support component 800 is folded and folded together with the enclosure component 900.

[0066] Compared to telescopic components, the foldable storage configuration of the support component 800 in this embodiment is generally more efficient because the folding portion can be folded away, thereby reducing the space occupied by the support structure and saving space. Telescopic support structures are relatively complex, and the telescopic process may involve multiple connecting parts. Over time, these connections may loosen or wear, affecting stability. The folding design, by reducing moving parts, helps improve the structural robustness.

[0067] In one embodiment, please refer to Figures 5 to 8 The support assembly 800 includes a slider 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 slider 820. The slider 820 is slidably disposed on the enclosure assembly 900, and the second end of the support rod 810 is rotatably connected to the enclosure frame assembly 200. Alternatively, the slider 820 is slidably disposed on the enclosure frame assembly 200, and the second end of the support rod 810 is rotatably connected to the enclosure assembly 900.

[0068] The slider 820 is typically a component that can slide on the fencing assembly 900 or the frame assembly 200. It adjusts the position of the support rod 810 by sliding, allowing the support rod 810 to be adjusted in angle or position as needed, thereby enabling flexible adjustment of the fencing assembly 900. The slider 820 may be connected to the fencing assembly 900 or the frame assembly 200 via a slide rail, slide groove, or other sliding connection device. In some embodiments, the slider 820 is integrally formed with the support rod 810.

[0069] The support rod 810 has two opposing ends. The first end is rotatably connected to the slider 820, meaning the support rod 810 can rotate relative to the connection point of the slider 820. The second end of the support rod 810 is connected to the enclosure assembly 900 or the frame assembly 200. For example:

[0070] Example 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 enclosure assembly 200. Thus, the first end of the support rod 810 is rotatably connected to the sliding member 820, 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 allowing the enclosure assembly 900 to switch between a first position and a second position.

[0071] Example 2: When the slider 820 is slidably disposed on the frame assembly 200, the slider 820 is connected to the frame assembly 200. That is, the second end of the support rod 810 is rotatably connected to the fence assembly 900. Thus, the sliding adjustment function of the slider 820 is to adjust the state of the fence 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 fence assembly 900 according to the sliding of the slider 820 on the frame assembly 200, thereby realizing the adjustable support of the fence assembly 900, or allowing the fence assembly 900 to switch between a first position and a second position.

[0072] In this embodiment, the combination of the slider 820 and the support rod 810 allows the enclosure assembly 900 to rotate and switch between different positions, and can be flexibly adjusted as needed.

[0073] In one embodiment, please refer to Figure 1The enclosure assembly 200 includes a pair of oppositely arranged side frames 210 and a connecting frame 220 connected to the pair of side frames 210; the enclosure assembly 900 includes a pair of oppositely arranged enclosure rods 910 and a connecting rod 920 connected between the pair of enclosure rods 910, the pair of enclosure rods 910 are rotatably mounted on the pair of side frames 210 respectively, and the connecting rod 920 is located at the end of the enclosure rod 910 away from the side frame 210; among the pair of enclosure rods 910 and the pair of side frames 210, a support assembly 800 is correspondingly provided for one enclosure rod 910 and one side frame 210; wherein, the sliding member 820 is provided 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 enclosure assembly 200 includes a pair of oppositely arranged side frames 210 and a connecting frame 220 connected to the pair of side frames 210. The side frames 210 form the side boundaries of the enclosure, providing support and fixing the structure of the entire enclosure assembly 200. They are interconnected by the connecting frame 220 to form a frame structure. The connecting frame 220 connects the pair of side frames 210 together, providing support and enhancing the overall stability of the frame while preventing deformation of the enclosure shape. The connecting frame 220 can be a single link or multiple links.

[0075] The enclosure assembly 900 includes a pair of opposing enclosure rods 910 and a connecting rod 920 connecting the pair of enclosure rods 910. The assembly formed by the pair of enclosure rods 910 and the connecting rod 920 serves as an enclosure. The enclosure rods 910 are rotatably mounted on the enclosure frame assembly 200. The connecting rod 920 ensures that the enclosure rods 910 maintain a consistent structural distance, which helps to enhance the stability of the enclosure and reduce the possibility of the pair of enclosure rods 910 separating due to external forces. The enclosure rods 910 can rotate within a certain range, so that the enclosure can be opened, closed, or adjusted as needed, thereby opening or closing the accommodating space 11.

[0076] The slider 820 is movable along the length of the retaining rod 910, enabling the retaining rod 910 to be adjusted and displaced. The support rod 810 is rotatably connected to the side frame 210, allowing the support assembly 800 to be adjusted at different angles.

[0077] The retaining rod 910 is rotatably mounted on the side frame 210. The retaining rod 910 may be installed on the upper part or the middle part of the side frame 210. In some embodiments, the retaining rod 910 may also be installed on the lower part of the side frame 210, for example, on the side of the side frame 210 near the connecting frame 220.

[0078] For example, the fence 910 is rotatably mounted on the upper part of the side frame 210. The upper part can be divided by the total height of the side frame 210, with the midline of the total height of the side frame 210 as the dividing line. The part above the dividing line is the upper part of the vehicle body 10. For example, the connection between the fence assembly 900 and the vehicle body 10 can be at a position one-half, one-third, or one-quarter away from the dividing line, or it can be at the point where the distance from the dividing line is the greatest.

[0079] In this embodiment, by rotating the enclosure rod 910 to the upper part of the side frame 210, when the enclosure assembly 900 rotates from the first position to the second position, the side where the connecting rod 920 is located moves towards the bottom assembly 100. At this time, the pair of enclosure rods 910 are folded into the side frame 210, and the connecting rod 920 is folded into the bottom assembly 100. In this way, the enclosure assembly 900 will not be laid in front of the opening. Thus, the user can take or put away items from the front of the opening, or enter or exit from the front of the opening. This makes it more convenient for the user to take or put away items, and makes it easier to enter and exit the accommodating space 11.

[0080] In one embodiment, the side frame 210 includes a first side rod 211, a second side rod 212, and a third side rod 213. The first ends of the first side rod 211 and the third side rod 213 are respectively connected to the bottom assembly 100, and the second ends of the first side rod 211 and the third side rod 213 are respectively connected to the second side rod 212. The first side rod 211 is inclined relative to the bottom assembly 100, and the second end of the support rod 810 is rotatably connected to the first side rod 211. The second side rod 212 is located at the top of the side frame 210. The second side rod 212 extends horizontally and has a front end and a rear end. The surrounding rod 910 is rotatably mounted 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 extends along the length 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 rod 211, the second side rod 212, and the third side rod 213 constitute the skeleton structure of the side frame 210. The first side rod 211 and the third side rod 213 are connected to the bottom component 100 and form the supporting foundation of the side frame 210. The second side rod 212 is located at the top of the side frame 210 and extends horizontally, serving to connect and support other components of the frame. The first end of the first side rod 211 and the third side rod 213 are connected to the bottom component 100, and the second end is connected to the second side rod 212. The connection method between the first side rod 211 and the third side rod 213 can be a rotatable connection, a fixed connection, a detachable connection, or the first side rod 211 can be telescopically extended; any method that can support the structure of the side frame 210 is acceptable.

[0082] Preferably, the first ends of the first side rod 211 and the third side rod 213 can be 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. The third side rod 213 can be telescopically extended or folded (e.g., ...). Figures 12 to 14 This allows the side frame 210 to fold, further increasing the folding rate of vehicle 1 and making vehicle 1 smaller in height after folding.

[0083] The enclosure rod 910 is rotatably mounted on the front end of the second side rod 212, meaning it is installed on top of the side frame 210. The mounting position of the enclosure rod 910 requires it to be able to rotate between a first position and a second position. The connecting frame 220 is connected to the rear end of the second side rod 212, forming a complete enclosure structure and ensuring a secure connection between the enclosure rod 910 and the side frame 210. The support rod 810, rotatably connected to the first side rod 211, can provide appropriate support force under different usage requirements, ensuring the stability of the enclosure structure.

[0084] Thus, in this embodiment, the enclosure assembly 900 has two main structural changes in position: First position (triangular structure): In this position, the enclosure rod 910, support rod 810, and first side rod 211 form a stable triangular structure. This triangular structure is very stable and can effectively disperse external forces, ensuring that the enclosure assembly 900 remains stable and robust in this state. Second position (folded state): In the second position, the support rod 810 folds between the first side rod 211 and the enclosure rod 910, allowing the enclosure assembly 900 to be compactly stored when not in use, facilitating storage and transportation.

[0085] In the technical solution of this embodiment, in the first position, the enclosure assembly 900 has good structural stability, forming an enclosed storage space 11 with at least the bottom and all sides closed, which can carry people and goods. 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 carrier 1, allowing users to put and take items in and out of the storage space 11. This significantly reduces the space occupied by the entire enclosure assembly 900, making it easier to store and transport. This design gives the enclosure assembly 900 both stability and ease of transport and storage, and it has the ability to flexibly adapt to different occasions.

[0086] To enhance the stability of the frame assembly 200 in the unfolded state, a locking mechanism can be provided at the rotatable connections of the first side rod 211, the second side rod 212, and the third side rod 213. For example, by providing a spring pin lock or a knob locking device 500, the connections between each side rod can be securely locked when the frame assembly 200 is unfolded, preventing the side rods from loosening or folding during use.

[0087] To ensure the frame assembly 200 can be stored compactly when folded and to prevent damage from excessive folding, a folding limiting structure can be installed at the rotating connection of the side rods. The limiting structure can be a limiting groove or a limiting pin. When the side rods are in the folded state, the limiting structure will automatically limit their folding angle, allowing each side rod to be folded tightly together, thereby reducing the space occupied.

[0088] To enhance ease of operation, the side rod connections can be equipped with quick-release mechanisms, allowing users to quickly fold or unfold the side rods without using the frame assembly 200. For example, by employing push-button or push-pull locking devices, users can easily unfold and fold 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 extends along the length direction of the surrounding rod 910; a 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 830 typically serves as the track for the sliding member 820. The function of the sliding support 830 is to provide support for the sliding member 820 and limit its range of motion on the surrounding rod 910. The sliding support 830 is installed on the surrounding rod 910 and extends along the length of the surrounding rod 910, making the overall structure of the carrier 1 more compact and easier to control the unfolding and folding of the support assembly 800.

[0091] The sliding member 820 is typically a sliding sleeve, which is fitted onto the sliding support member 830. By fitting onto the sliding support member 830, the sliding member 820 can move along the length of the support member, thereby changing the position or shape of the retaining rod 910. In other embodiments, the sliding member 820 can also be a slider, and the sliding support member 830 is provided with a groove that is adapted to slide and connect with the slider.

[0092] The technical solution of this embodiment combines the sliding support 830 and the sliding member 820. The sliding support 830 serves as the track for the sliding member 820, providing stable support and guidance along the length of the retaining rod 910.

[0093] In one embodiment, such as Figures 4 to 8 The sliding support 830 is located on the inner side of the retaining rod 910. Here, "inner side of retaining rod 910" refers to the side of a pair of retaining rods 910 that is closest to each other. The vehicle 1 also requires a fabric cover, which is typically used to protect the enclosure assembly 900, or to provide aesthetic appeal or protective functionality. At the frame assembly 200 and retaining rod 910 assemblies, the fabric cover is usually located on the outer side, while the sliding support 830 is located on the inner side of the retaining rod 910. This allows the movement trajectory of the sliding member 820 and the installation space of the fabric cover to avoid each other. Placing the sliding support 830 on the inner side reduces the complexity of the fabric cover installation process by requiring it to be bypassed, thus simplifying the fabric cover installation process and improving the aesthetics of the vehicle 1.

[0094] In this embodiment, the sliding support 830 is placed on the inner side of the fence 910, which avoids direct contact between the fabric cover and the sliding support 830, thereby protecting the fabric cover from wear. Secondly, it improves the neatness and aesthetics of the fence appearance. In addition, the installation and covering of the fabric cover becomes simpler, 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, which includes a locking component 510 and an unlocking component 520. The locking component 510 is movably switchable between a locked position and an unlocked position on the fence 910. The unlocking component 520 is drivenly connected to the locking component 510. In the locked position, the locking component 510 is located in the locking groove 821 to lock the sliding member 820 to the sliding support member 830, thereby fixing the fence assembly 900 in the first position. During the process of switching the locking component 510 from the locked position to the unlocked position, the unlocking component 520 drives the locking component 510 to move toward the unlocked position so that the locking component 510 disengages from the locking groove 821. In the unlocked position, the locking component 510 disengages from the locking groove 821, and the sliding member 820 can slide along the sliding support member 830 so that the fence assembly 900 can rotate and switch between the first position and the second position.

[0096] When locked, the locking component 510 is located in the locking groove 821 of the slider 820, fixing the slider 820 to the sliding support 830, thereby fixing the enclosure component 900 in the first position. The function of the locking component 510 is to prevent the slider 820 from moving along the sliding support 830, so that the position of the enclosure component 900 does not change during use, making it difficult for the enclosure component 900 to easily open the side opening during the operation of the vehicle 1, reducing the chance of the loaded object falling out of the accommodating space 11.

[0097] The unlocking component 520 is driven to connect with the locking component 510. When the locking component 510 switches from the locked position to the unlocked position, the unlocking component 520 drives the movement of the locking component 510, causing the locking component 510 to disengage from the locking slot 821. The unlocking component 520 can be installed on the connecting rod 920 of the enclosure component 900, or it can be installed on a pair of enclosure rods 910 respectively.

[0098] The locking device 500 can be a mechanical locking device 500, an electromagnetic locking device 500, a pneumatic locking device 500, or a locking device 500 with a traction cable; no specific limitation is made here. To adapt to different location requirements, the locking device 500 can have a multi-level locking function, providing multiple locking positions at different rotation angles of the enclosure assembly 900. These multiple positions are between a first position and a second position. For example, the enclosure bar 910 can be locked at multiple angles such as 30°, 45°, 60°, or 90°. The aforementioned first and second positions are the limit positions of the enclosure assembly 900. In this way, users can flexibly adjust the angle of the enclosure bar 910 and lock it according to different usage scenarios (such as placing infants, placing or retrieving items, or allowing other passengers to get on and off independently), increasing the product's ease of use.

[0099] The locked position refers to the position where the locking component 510 is located within the locking groove 821, the sliding member 820 is locked, and the position of the enclosure component 900 is fixed. In this position, the enclosure cannot move freely and can remain in its current first position. The unlocked position refers to the position where the locking component 510 is disengaged from the locking groove 821, allowing the sliding member 820 to slide along the sliding support member 830, thus enabling the enclosure component 900 to switch between the first and second positions or rotate.

[0100] When the position of the fencing component 900 needs to be adjusted, the user can switch the position of the locking component 510 by operating the unlocking component 520. In the locked state, the locking component 510 is located in the locking groove 821, fixing the slider 820 to the sliding support 830, and the fencing component 900 is in the first position, unable to move or be adjusted freely. When the position needs to be adjusted, the unlocking component 520 is triggered or operated, causing it to drive the locking component 510 to move to the unlocked position, thereby disengaging the locking component 510 from the locking groove 821. At this time, the slider 820 is no longer locked and can slide freely along the sliding support 830. Adjusting the position of the fencing component 900, once the locking component 510 is disengaged from the locking groove 821, the slider 820 can slide freely on the sliding support 830, and the fencing component 900 can move between the first and second positions. After adjusting the position of the fencing, the user can manually or automatically move the locking component 510 back to the locked position, locking the slider 820, thus fixing the fencing component 900 in the first position.

[0101] In this embodiment, the locking component 510 prevents the fencing component 900 from moving arbitrarily, thereby maintaining stability. Especially when the fencing position needs to be fixed for a long time, the locking device 500 provides reliable protection and prevents the fencing component 900 from being displaced unnecessarily due to external interference.

[0102] In one exemplary embodiment, please refer to Figure 1 , Figures 5 to 7 The unlocking component 520 includes an operating element 521 and two unlocking elements 522. The operating element 521 is located on the connecting rod 920, and the two unlocking elements 522 are respectively located on a pair of surrounding rods 910. The operating element 521 and the two unlocking elements 522 are connected by a traction cable. The unlocking element 522 is provided with an unlocking groove 522a, which faces the locking component 510. The locking component 510 includes a mounting base 511 and a locking element 512 located on the mounting base 511. The locking element 512 is provided with a first engaging portion 513 and a second engaging portion 514. In the locked position... When the locking component 510 switches from the locked position to the unlocked position, the user can control the unlocking component 522 to move toward the locking component 510 by pressing or sliding the operating element 521, so that the second locking part 514 engages with the unlocking groove 522a and the first locking part 513 slides out of the locking groove 821. When in the unlocked position, the first locking part 513 disengages from the locking groove 821 and the second locking part 514 engages with the unlocking groove 522a.

[0103] The locking assembly 510 includes a mounting base 511 and a locking member 512 disposed on the mounting base 511. The locking member 512 includes two engaging portions. When the first engaging portion 513 is in the locked state, it engages with the locking groove 821 on the connector, fixing the locking assembly 510 in the locked position so that the enclosure assembly 900 is fixed in the current position. The second engaging portion 514 cooperates with the unlocking groove 522a to unlock the device. When the locking member 512 switches from the locked state to the unlocked state, the second engaging portion 514 engages with the unlocking groove 522a.

[0104] The unlocking component 520 includes an operating element 521 and an unlocking element 522. The operating element 521 is mounted on the connecting rod 920 and serves as a user-operated component. The user can control the movement of the unlocking element 522 by pressing or sliding the operating element 521. The design of the operating element 521 should ensure that the user can easily access and operate it; it is typically a handle, button, or slider. The unlocking element 522 has an unlocking groove 522a facing the locking component 510. The unlocking groove 522a engages with the second latching part 514 in the locking component 510. The unlocking element 522 and the operating element 521 are connected by a traction cable. The traction cable acts as a transmission tool, transmitting the movement of the operating element 521 to the unlocking element 522. When the user operates the operating element 521, the traction cable moves the unlocking element 522 toward the locking component 510, thereby switching the state of the locking component 510.

[0105] In this embodiment, locking and unlocking are achieved by combining the operating component 521, the unlocking component 522, the traction cable, and the snap-fit ​​mechanism, which realizes stable switching of the enclosure component 900 between different positions. Users can easily unlock or lock the enclosure component 900 by pressing the button or sliding the slider.

[0106] In one embodiment, the vehicle body 10 further includes a push rod assembly 300, which is disposed on the side of the enclosure assembly 120 away from the barrier 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 are rotatably connected to the enclosure assembly 120, so that the push rod assembly 300 has a first use state and a second use state.

[0107] In this embodiment, the vehicle body 10 also includes a push rod assembly 300, which is located on the side of the enclosure assembly 120 opposite to the barrier 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 connected to the enclosure assembly 120 via a hinge or a rotating shaft. Thus, the push rod assembly 300 can switch between two states under different usage requirements: the first usage state is the push rod unfolded state, used to push the vehicle; the second usage state is the push rod folded state, convenient for 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, parallel or nearly parallel, and the second push rod 320 connects to the first push rod 310 and the third push rod 330, thus making the push rod assembly 300 as a whole approximately "U" shaped. In this way, the first push rod 310 and the third push rod 330, arranged side by side, form the two main support structures of the cart, distributing the force and increasing the overall stability of the cart. The "U" shaped design of the push rod assembly 300 makes the operation of the push rod more ergonomic. Users can obtain a larger pushing angle and more control space when pushing or pulling, making the vehicle 1 more flexible and effortless when turning and moving.

[0109] To improve the operational stability of the push rod assembly 300, a folding locking mechanism can be provided at the rotatable connection between the push rod and the frame assembly 120. This mechanism can employ a spring pin, a knob locking device, or a traction cable locking device, ensuring that the push rod is securely unfolded and fixed in a suitable position in the initial use state, preventing accidental folding during use. When the push rod assembly 300 is not in use, the locking device can be released by pressing or rotating the push rod for easy and quick folding and storage.

[0110] Furthermore, to enhance operational comfort, the top of the push rod can be equipped with a non-slip grip. The grip can be made of soft rubber or silicone material, with a textured surface or non-slip coating to prevent the user's hands from slipping when pushing the vehicle, thus improving operational safety and comfort.

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

[0112] The push rod assembly 300 can be designed with an automatic pop-out function. Through a spring or pneumatic structure, the user only needs to press a button to automatically pop the push rod out from the folded state to the unfolded state, improving the ease of operation.

[0113] In one embodiment, the vehicle 1 further includes a tow bar assembly 400, which is movably switchable between a third position and a fourth position at the bottom of the vehicle body 10; in the third position, the tow bar assembly 400 is housed 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] Please see Figure 1 , Figures 8 to 11 In this embodiment, the vehicle 1 includes a tow bar assembly 400, which can move and switch between a third position and a fourth position. The tow bar assembly 400 is designed to be used in different working states, providing users with a flexible operating method.

[0115] In the third position, the tow bar assembly 400 is completely housed within the vehicle body 10. This housing configuration aims 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 traveling at high speeds, effectively reducing air resistance and improving the vehicle 1's driving stability and efficiency. Furthermore, housing the tow bar assembly 400 within the vehicle body 10 also prevents damage from the external environment, such as collisions or scratches, when the assembly is not in operation, 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 carrier body 10 to perform specific operational tasks, such as providing towing, support, or connection to other equipment. At this time, the tow bar assembly 400 can be secured in the fourth position by a locking mechanism to ensure its stability and reliability during operation. The extension mechanism of the tow bar assembly 400 can employ linear telescopic, rotary, or other mechanical structures to adapt to different application scenarios. The extension length of the tow bar assembly 400 can be adjusted according to user needs to achieve diverse functionalities.

[0117] Based on the previous embodiment, the bottom of the vehicle body 10 is provided with a first mounting groove 12 and a second mounting groove 13; the tow rod assembly 400 includes a tow rod body 410 and an extension rod 420, the tow rod body 410 has a drag end and a connecting end, and the extension rod 420 is rotatably connected to the connecting end; in the third position, at least a portion of the extension rod 420 is received in the first mounting groove 12, and at least a portion of the tow rod body 410 is received in the second mounting groove 13; in the fourth position, at least a portion of the extension rod 420 is received in the second mounting groove 13, the tow rod body 410 is located outside the first mounting groove 12 and the second mounting groove 13, and the tow rod body 410 can rotate relative to the extension rod 420.

[0118] In this embodiment, the bottom of the vehicle body 10 is provided with a first mounting groove 12 and a second mounting groove 13. The mounting grooves are designed to accommodate different parts of the tow bar assembly 400 so as to realize smooth switching of the tow bar assembly 400 between the third position and the fourth position. The first mounting groove 12 and the second mounting groove 13 are both arranged along the longitudinal direction of the bottom of the vehicle 1 and have a cavity structure adapted to the shape of the tow bar assembly 400 so as to ensure the stability and accuracy of the tow bar assembly 400 during the receiving and extending process.

[0119] For example, the tow bar assembly 400 includes a tow bar body 410 and an extension bar 420. The dragging end of the tow bar body 410 is designed to connect to a towing device or item, while the connecting end is rotatably connected to the extension bar 420. The extension bar 420 is connected to the connecting end of the tow bar body 410 via a pivot or hinge structure to achieve smooth rotation of the tow bar body 410 between different positions. This rotatable connection structure allows the tow bar body 410 to automatically adjust to the working angle when moved to the fourth position, improving the efficiency of the towing operation.

[0120] When the tow bar assembly 400 moves to the fourth position, at least a portion of the extension bar 420 will be received within the second mounting slot 13, while the tow bar body 410 will be completely or partially outside the first mounting slot 12 and the second mounting slot 13. At this time, the tow bar body 410 rotates relative to the extension bar 420, thereby positioning the dragging end at an angle suitable for towing operations, which helps to improve the efficiency and stability of towing.

[0121] In one embodiment, the tow bar body 410 includes a first tow bar 411, a second tow bar 412 and a third tow bar 413 connected in sequence.
