Technical Field

[0001] This utility model relates to the field of transportation device technology, and in particular to a vehicle. Background Technology

[0002] Currently, vehicles that are driven by pushing or pulling, such as trolleys and trailers, are usually equipped with a seat structure to enable them to carry people. For ease of daily storage and carrying, the seat structure is usually designed to be foldable. However, while folding the seat reduces the size, it cannot be used to carry cargo, resulting in a relatively limited function for the vehicle. Utility Model Content

[0003] The main purpose of this utility model is to propose a vehicle that aims to solve the problem of the limited functionality of existing vehicles.

[0004] To achieve the above objectives, the vehicle proposed in this utility model includes:

[0005] The frame has two first sides located in a first horizontal direction and two second sides located in a second horizontal direction;

[0006] The support structure includes two side assemblies, correspondingly disposed on the two first sides. Each side assembly includes three links and a locking structure. One end of the two side links is rotatably connected to the first side of the frame, and the other end is rotatably connected to both ends of the middle link. The locking structure is disposed at the connection point of two adjacent links or at the connection point of the link to the frame. The locking structure has a locked state and an unlocked state. In the locked state, it restricts the rotation of the corresponding link; in the unlocked state, it releases the restriction on the corresponding link.

[0007] A support member is used to support the support structure when the support structure is in the deployed state.

[0008] In one embodiment, the two adjacent links include a first link and a second link, which are rotatably connected about a first axis by a rotatable connection structure. The rotatable connection structure includes two mounting seats that are opposite to each other and rotatably arranged in a first horizontal direction, and the two mounting seats are connected to one end of the first link and the second link respectively.

[0009] The locking structure includes a locking member movably disposed between the two mounting seats, having a locked position and an unlocked position. In the locked position, the locking member engages with the two mounting seats to restrict their rotation. In the unlocked position, the locking member disengages from at least one of the mounting seats, allowing the two mounting seats to rotate relative to each other.

[0010] In one embodiment, the two connecting rods located on both sides include a first connecting rod and a third connecting rod. The first connecting rod is rotatably connected to the vehicle frame about a second axis. The lower end of the third connecting rod is rotatably connected to the vehicle frame about a third axis, and the upper end is rotatably connected to the second connecting rod about a fourth axis. The first axis, the second axis, the third axis, and the fourth axis are arranged in parallel.

[0011] In one embodiment, the support structure further has a folded state capable of being folded into the frame, wherein when folded from the unfolded state to the folded state, the first axis moves toward the direction closer to the third axis; and / or,

[0012] The support structure also includes a fourth link to form a frame with the two third links, the first link and the second link being folded within the frame.

[0013] In one embodiment, one end of the bearing member is hinged to the third connecting rod, and the other end is hinged to the first connecting rod via a connecting rod, so that when the connecting rod is folded, the bearing member is folded back, so that the bearing member is folded back within the frame.

[0014] In one embodiment, the locking member is movably disposed on one of the mounting bases along a first horizontal direction.

[0015] In one embodiment, a limiting engagement structure is provided between the locking member and each of the mounting seats. The limiting engagement structure includes a limiting part and a engaging part. One of the limiting part and the engaging part is disposed on the locking member, and the other is disposed on the mounting seat. The limiting part and / or the engaging part are provided in multiple circumferential directions along the rotation axis of the mounting seat. Among the limiting part and the engaging part, one is a limiting protrusion, and the other is a engaging groove.

[0016] In one embodiment, at least one of the mounting bases is provided with a drive member for driving the locking member to move between the locked position and the unlocked position; and / or,

[0017] At least one of the mounting bases is provided with an elastic element, which is located between the corresponding mounting base and the locking element, for resetting the locking element to the locked position.

[0018] In one embodiment, the two connecting rods located on both sides include a first connecting rod and a third connecting rod;

[0019] One end of the bearing member is hinged to the third connecting rod, and the other end is hinged to the first connecting rod via a connecting rod.

[0020] In one embodiment, the frame includes a first bracket and a second bracket rotatably mounted on the first bracket about an axis extending in a first horizontal direction. The first bracket and the second bracket are each provided with a support structure, and the two support structures are independently provided.

[0021] In one embodiment, the two support structures are arranged opposite to each other to form a passageway between the two support structures; and / or,

[0022] A side baffle structure is provided between the two support structures. The side baffle structure includes a side baffle member, the two ends of which are respectively connected to the two support structures.

[0023] In the technical solution of this utility model, when the vehicle needs to carry passengers, the locking structure first moves to the unlocked state to release the lock on the side panel assembly, allowing the support structure to move away from the frame to the unfolded state. Then, the locking structure moves to the locked position to lock the side panel assembly, allowing the support structure to remain in the unfolded state to support the support member, enabling the vehicle to be used for carrying passengers. When the vehicle needs to carry cargo, the locking structure first moves to the unlocked state to release the lock on the side panel assembly, allowing the support structure to move closer to the frame to the folded state. Then, the locking structure moves to the locked position to lock the side panel assembly, allowing the support structure to remain in the folded state, enabling the vehicle to be used for carrying cargo. Thus, by setting the side panel assembly and the locking structure, the support structure can be kept in either the unfolded or folded state. When the support structure is in the unfolded state, it can support the support member, enabling the vehicle to be used for carrying passengers. When the support structure is in the folded state, the support structure and the support member can be folded horizontally on the frame, enabling the vehicle to be used for carrying cargo.

[0057] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0058] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0059] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0060] Currently, vehicles that are driven by pushing or pulling, such as trolleys and trailers, are usually equipped with a seat structure to enable them to carry people. For ease of daily storage and carrying, the seat structure is usually designed to be foldable. However, while folding the seat reduces the size, it cannot be used to carry cargo, resulting in a relatively limited function for the vehicle.

[0061] Based on this, this utility model proposes a vehicle aimed at solving the problem of the limited functionality of existing vehicles. Among other things, Figures 1 to 22 A schematic diagram of the structure of the vehicle provided by this utility model.

[0062] Please see Figures 1 to 12In one embodiment of this utility model, the carrier 100 includes a frame 1, a support structure 2, and a support member 3. It has two first sides 111 located in a first horizontal direction and two second sides 112 located in a second horizontal direction. The support structure 2 includes two side assemblies 21, which are correspondingly disposed on the two first sides 111. Each side assembly 21 includes three connecting rods and a locking structure 22. One end of the two connecting rods located on both sides is rotatably connected to the first side 111 of the frame 1, and the other end is rotatably connected to both ends of the connecting rod located in the middle. The locking structure 22 is disposed at the connection point of two adjacent connecting rods or at the connection point of the connecting rod and the frame 1. The locking structure 22 has a locked state and an unlocked state. In the locked state, it restricts the rotation of the corresponding connecting rod. In the unlocked state, it releases the restriction on the corresponding connecting rod. The support member 3 is used to support the support structure 2 when the support structure 2 is in the unfolded state.

[0063] It should be noted that the frame 1 is mainly used to bear the load and needs to have a certain degree of rigidity and strength. Its material can be various; specifically, the frame 1 can be made of metals such as iron and aluminum, alloys such as steel and aluminum alloys, or inorganic non-metallic materials such as nano-ceramics. This utility model does not limit this. Similarly, the bearing member 3 can be made of various materials, including metals such as iron and aluminum, alloys such as steel and aluminum alloys, or inorganic non-metallic materials such as nano-ceramics, as long as the strength requirements are met. This utility model does not limit this. Further details can be found in the following sections. Figure 1 and Figure 2 When the support structure 2 is in the deployed state, the two side panels 21 stand upright on the two first sides 111 of the frame 1, so that the support structure 2 can support the support member 3. In particular, there are various types of vehicles 100. In this embodiment, the vehicle 100 includes a child trailer or a child stroller. It is understood that a child trailer or child stroller can be a stroller or trailer that a child can drive, or a stroller or trailer that a child can ride in, etc. This utility model does not limit this.

[0064] In the technical solution of this utility model, when the vehicle 100 needs to carry passengers, the locking structure 22 first moves to the unlocked state to release the lock on the side panel assembly 21, allowing the support structure 2 to move away from the frame 1 to the unfolded state. Then, the locking structure 22 moves to the locked position to lock the side panel assembly 21, allowing the support structure 2 to remain in the unfolded state to support the support member 3, enabling the vehicle 100 to be used for carrying passengers. When the vehicle 100 needs to carry cargo, the locking structure 22 first moves to the unlocked state to release the lock on the side panel assembly 21, allowing the support structure 2 to move closer to the frame 1 to fold into place. The frame 1 is folded, and then the locking structure 22 moves to the locking position to lock the side panel assembly 21, so that the support structure 2 can remain in the folded state, allowing the vehicle 100 to be used for carrying goods. Thus, by setting the side panel assembly 21 and the locking structure 22, the support structure 2 can be kept in either the unfolded or folded state. When the support structure 2 is in the unfolded state, the support structure 2 can support the support member 3, so that the vehicle 100 can be used for carrying people. When the support structure 2 is in the folded state, the support structure 2 and the support member 3 can be folded horizontally on the frame 1, so that the vehicle 100 can be used for carrying goods.

[0065] Furthermore, the first horizontal direction can be varied. For example, the first horizontal direction can be the width direction of the frame 1 or the length direction of the frame 1, etc. This utility model does not limit this. Specifically, in this embodiment, the first horizontal direction is the width direction of the frame 1, so that the two linkage assemblies are arranged along the width direction of the frame 1, so that when the vehicle 100 carries people, the orientation of the passengers is consistent with the direction of movement of the vehicle 100, thereby improving the comfort of passengers.

[0066] In one embodiment of this utility model, please refer to Figures 1 to 12Two adjacent links include a first link 211 and a second link 212. The first link 211 and the second link 212 are rotatably connected about a first axis via a rotating connection structure 23. The rotating connection structure 23 includes two mounting seats 231 that are opposite to each other and rotatably arranged in a first horizontal direction. The two mounting seats 231 are connected to one end of the first link 211 and the second link 212 respectively. The locking structure 22 includes a locking member 221, which is movably disposed between the two mounting seats 231 and has a locked position and an unlocked position. In the locked position, the locking member 221 cooperates with the two mounting seats 231 to restrict the rotation of the two mounting seats 231. In the unlocked position, the locking member 221 is disengaged from at least one of the mounting seats 231 so that the two mounting seats 231 can rotate relative to each other. When the first link 211 and the second link 212 need to be locked, the locking member 221 moves to the locked position. In this configuration, the locking element 221 is positioned between the two mounting seats 231 to cooperate with the two mounting seats 241, restricting the rotation of the two mounting seats 231 and thereby locking the first link 211 and the second link 212. When the first link 211 and the second link 212 need to rotate, the locking element 221 moves to the unlocked position. At this time, the locking element 221 can release the rotation restriction on the two mounting seats 231, allowing the first link 211 and the second link 212 to rotate relative to each other. Thus, by setting the mutually cooperating mounting seats 231 and locking element 221, the locking element 221 can both restrict the rotation of the two mounting seats 231 and prevent the two mounting seats 231 from rotating relative to each other, and release the rotation restriction on the two mounting seats 231, allowing the first link 211 and the second link 212 to rotate relative to each other, thereby enabling the support structure 2 to switch between the folded state and the unfolded state.

[0067] In one embodiment of this utility model, please refer to Figures 3 to 6 The two connecting rods on both sides include a first connecting rod 211 and a third connecting rod 213. The first connecting rod 211 is rotatably connected to the frame (1) around the second axis. The lower end of the third connecting rod 213 is rotatably connected to the frame 1 around the third axis, and the upper end is rotatably connected to the second connecting rod 212 around the fourth axis. The first axis, the second axis, the third axis and the fourth axis are arranged in parallel so that the first axis, the second axis, the third axis and the fourth axis are arranged in approximately parallel so that the first connecting rod 211, the second connecting rod 212 and the third connecting rod 213 can form a four-bar linkage with the frame 1. This facilitates the switching of the side panel assembly 21 between the unfolded state and the folded state, and can also evenly distribute the force of the bearing member 3 to the frame 1 to avoid excessive force on a single point.

[0068] In one embodiment of this utility model, please refer to Figures 5 to 8The support structure 2 also has a folded state that can be folded into the frame 1. When folding from the unfolded state to the folded state, the first axis moves towards the direction closer to the third axis, so that the first link 211 and the second link 212 can be folded between the third link 213 and the frame 1, thereby reducing the size of the side panel assembly 21 in the length direction of the frame 1 after folding, making the support structure smaller and easier to store. Of course, in another embodiment, the first axis can also move away from the third axis, so that the first link 211 and the second link 212 can be folded outside the third link 213 and the frame 1, but this method will increase the size of the side panel assembly 21 in the length direction of the frame.

[0069] In one embodiment of this utility model, please refer to Figures 5 to 8 The support structure 2 also includes a fourth link 214 to form a frame with the two third links 213. The first link 211 and the second link 212 are folded inside the frame. Thus, by setting the fourth link 214 to connect with the two third links 123 to form a frame on the frame 1, the two side panel components 21 can be connected, allowing them to move in tandem and avoid the user having to drive the two side panel components 21 separately. This makes it convenient for the user to switch the state of the support structure 2. At the same time, the first railing 211 and the second link 212 can be folded inside the frame, allowing the side panel components 21 to support the frame, which helps to improve the load-bearing capacity of the support structure 2. This allows the support structure 2 in the folded state to support heavier items.

[0070] To connect the bearing member 3 to the support structure 2, please refer to... Figures 5 to 8One end of the support member 3 is hinged to the third connecting rod 213, and the other end is hinged to the first connecting rod 211 via a connecting rod 215. When the connecting rod is folded, the support member 3 folds down, allowing it to fold within the frame. Thus, by providing the connecting rod 215 to connect the support member 3 to the first connecting rod 211, the support member 3 can move in conjunction with the side panel assembly 21. When the support structure 2 is in the unfolded state, the support member 3 can support itself on the support structure 2 for carrying passengers. When the support structure 2 is in the folded state and the side panel assembly 21 is folded into the frame 1, the support member 3 can fold within the frame, allowing it to fold roughly horizontally onto the frame 1, enabling the frame 1 to be used for carrying goods. It is understood that the support member 3 can be a support plate or a support frame, etc., and this utility model does not limit this. Of course, there are various ways to connect the support member 3 to the support structure 2. In another embodiment, one end of the support member 3 is hinged to the third link 213, and the other end is slidably connected to the first link 211 in the second horizontal direction. In this way, when the support structure 2 switches between the unfolded state and the folded state, the other end of the support member 3 can slide in the second horizontal direction so that the support member 3 can be placed horizontally on the frame 1 for carrying goods.

[0071] It should be noted that the above two related technical features, "the support structure 2 also includes a fourth connecting rod 214" and "one end of the bearing member 3 is hinged to the third connecting rod 213, and the other end is hinged to the first connecting rod 211 through the connecting rod 215", can be set either one or both, and this utility model does not limit them.

[0072] Furthermore, when the support structure 2 is in the unfolded state, the junction of the bearing member 3 and the connecting rod 215 is located inside the first connecting rod 211. In this way, when the bearing member 3 carries a person, the end of the connecting rod 215 away from the frame 1 can rotate downward, thereby enabling the support structure 2 to support the bearing member 3.

[0073] In one embodiment of this invention, when the support structure 2 is in the deployed state, the support member 3 is inclined and supports the support structure 2, so that the passenger leans back towards the third link 213, allowing the passenger to lean against the support structure 2 and preventing the passenger from falling over. Of course, in other embodiments, the support member 3 may also be horizontally arranged, etc., and this invention does not limit this.

[0074] In one embodiment of this utility model, please refer to the following: Figures 13 to 17 The locking member 221 is movably disposed on one of the mounting bases 231 along the first horizontal direction, so that the direction of movement of the locking member 221 is consistent with the rotation axis of the first link 211 or the second link 212, thereby facilitating the switching of the locking member 221 between the locked position and the unlocked position.

[0075] In one embodiment of this utility model, a limiting fit structure 223 is provided between the locking member 221 and each mounting base 231. The limiting fit structure 223 includes a limiting part and a fitting part. One of the limiting part and the fitting part is provided on the locking member 221, and the other is provided on the mounting base 231. The limiting part and / or the fitting part are provided in multiple ways along the circumferential direction of the rotation axis of the mounting base 231. In this way, by providing mutually fitting limiting parts and fitting parts, after the two mounting bases 231 rotate to the corresponding positions, the two mounting bases 231 are locked to restrict the relative rotation of the two mounting bases 231, so that the support structure 2 can maintain its current state.

[0076] It should be noted that in order to lock the two mounting bases 231 at different angles so that the rotation angle of the first link 211 and the second link 212 is adjustable, there are multiple ways to set the limiting part and the mating part. One of them can be set with multiple parts and the other with one part, or both can be set with multiple parts, so that one of the limiting part and the mating part can be selected to mat with the other part with different settings to limit the two mounting bases 231 at different angles.

[0077] Furthermore, one of them is a limiting protrusion 2231, and the other is a mating groove. Thus, by providing the mutually mating limiting protrusion 2231 and the mating groove, the rotation between the locking member 221 and the mounting base 231 is restricted. It is understood that there are various limiting mating structures 223. In other embodiments, the limiting mating structure 223 can also be used for limiting via a magnetic connection structure, etc., and this utility model does not limit it in this way.

[0078] In one embodiment of this utility model, at least one of the mounting bases 231 is provided with a driving member 222 for driving the locking member 221 to move between a locked position and an unlocked position. Thus, by providing the driving member 222 to drive the locking member 221 to move, the locking member 221 can switch between the locked and unlocked positions. Furthermore, the driving member 222 can be of various types, such as a button or a cylinder, etc. This utility model does not limit its application. Specifically, in this embodiment, the driving member 222 is a driving button, allowing the user to manually operate the locking member 221, which helps reduce the weight and cost of the support structure 2. It is understood that the driving member 222 can be made of various materials, such as metals like iron and steel, inorganic non-metallic materials like ceramics, or polymer materials like plastics, etc. This utility model does not limit its application. Furthermore, in order to facilitate the installation of the locking member 221, in one embodiment of this utility model, each mounting base 231 is provided with a mating groove, and two mounting grooves are mated to form a mounting cavity. The locking member 221 is disposed in the mounting cavity. In this way, by providing a mating groove to form a mounting cavity, the locking member 221 can be hidden in the mounting cavity, which can not only prevent the locking member 221 from being affected by external factors and protect the locking member 221, but also improve the appearance of the vehicle 100.

[0079] In one embodiment of this utility model, at least one of the mounting bases 231 is provided with an elastic element, which is located between the corresponding mounting base 231 and the locking member 221, for resetting the locking member 221 to the locked position. Thus, by providing the elastic element, the locking member 221 can be held in the locked position, thereby reducing the frequency of operation of the locking member 221 and improving the user experience. It is understood that the elastic element can be a spring, rubber, etc., and this utility model is not limited thereto. Furthermore, the locking member 221 is provided with an annular groove 2211 for installing the elastic element.

[0080] It should be noted that the two related technical features mentioned above, "at least one of the mounting bases 231 is provided with a driving member 222" and "at least one of the mounting bases 231 is provided with an elastic member", can be provided either one or both, and this utility model does not limit them.

[0081] To connect the two mounting bases 231, in this embodiment, each mounting base 231 is provided with a through hole. The side panel assembly 21 also includes a connector passing through the two through holes to connect the two mounting bases 231. Thus, by providing through holes and connectors, the two mounting bases 231 can be connected. Further, each mounting base 231 has a mounting boss extending along a first horizontal direction at its center, with a through hole located on the mounting boss. This allows the two mounting bosses to align when the two mounting bases 231 are connected, making the two through holes interconnected, allowing the connector to pass through. A locking member 221 is fitted onto the mounting boss. Further, the locking member 221 can be rotatably mounted on the mounting boss or anti-rotation mounted on the mounting boss; this invention does not limit this. Specifically, in this embodiment, the locking member 221 is anti-rotation mounted on the mounting boss to restrict the rotation of the locking member 221 and the mounting boss, thereby improving the locking effect of the locking member 221.

[0082] In one embodiment of this utility model, the two connecting rods located on both sides include a first connecting rod 211. The first connecting rod 211 is connected to the frame 1 through a rotation limiting structure 24. The rotation limiting structure 24 includes a limiting rib 241 and a limiting groove 242 respectively provided on the frame 1 and the frame 1. The limiting groove 242 extends circumferentially. The limiting rib 241 and the limiting groove 242 cooperate to limit the movement stroke of the first connecting rod 211 and prevent the first connecting rod 211 from flipping outward.

[0083] In one embodiment of this utility model, the vehicle 100 further includes a pull rod assembly 4, which includes a sleeve 41 and a pull rod 42. The sleeve 41 is disposed on the frame 1, and the pull rod 42 is movably installed in the sleeve 41 along the axial direction of the sleeve 41. When it is necessary to tow the vehicle 100, the pull rod 42 is pulled out of the sleeve 41 so that personnel or a towing mechanism can tow the vehicle 100. When it is not necessary to tow the vehicle 100, the pull rod 42 is hidden inside the sleeve 41 to avoid collision and help increase the safety of the vehicle 100. Thus, by setting the sleeve 41 to accommodate the pull rod 42, and by the movement of the pull rod 42, it is not only convenient to tow the vehicle 100, but also to increase the safety of the vehicle 100 and improve the appearance of the vehicle 100.

[0084] It should be noted that the sleeve 41 and the pull rod 42 can have various shapes, such as cylindrical or prismatic structures. This utility model does not limit these shapes. Furthermore, the sleeve 41 and the pull rod 42 can be made of various materials, such as iron, aluminum, or other metals, or steel, aluminum alloys, or inorganic non-metallic materials such as ceramics. This utility model does not limit these materials.

[0085] Furthermore, the sleeve 41 can be fixedly installed on the frame 1 or movably installed on the frame 1, etc. This utility model does not limit this, but the height will be different for different personnel or towing mechanisms, resulting in different tilt angles of the pull rod 42. Therefore, in this embodiment, the sleeve 41 is rotatably installed on the frame 1 around the axis extending in the first horizontal direction. In this way, the sleeve 41 is rotatably set so that the tilt angle of the pull rod 42 can be adapted to the towing height of the personnel or towing mechanism, thereby facilitating the personnel or towing mechanism to tow the vehicle 100.

[0086] In one embodiment of this utility model, the vehicle frame 1 includes a frame 12 and a storage component 13 disposed within the frame 12. Thus, by providing the frame 12, the storage component 13 can be mounted, and by providing the storage component 13, the vehicle 100 can be used to place items while carrying passengers. It is understood that the storage component 13 can be a shelf, a cloth, or anything else that can hold items; this utility model does not limit this.

[0087] In one embodiment of this utility model, please refer to the following: Figures 9 to 12 The frame 1 includes a first bracket 14 and a second bracket 15. The second bracket 15 is rotatably mounted on the first bracket 14 about an axis extending in a first horizontal direction. Within its travel range, the second bracket 15 has the ability to rotate to a storage position close to the first bracket 14 and to a load-bearing position for carrying the seat assembly. Each of the first bracket 14 and the second bracket 15 is provided with a support structure 2. The two support structures 2 are independently arranged. When the frame 1 is in the load-bearing position, the first bracket 14 and the second bracket 15 are flush with each other so that the frame 1 is in a horizontal state to support the two support structures 2, so that the two support structures 2 can be used to carry people or goods. When the frame 1 is in the storage position, the first bracket 14 and the second bracket 15 move closer to each other so that the frame 1 is in a folded state for storage or transportation. Thus, by rotating the second bracket 15, the frame 1 can support the two support structures 2 so that the support structures 2 can be used to carry people or goods, and the frame 1 can also be folded for convenient storage or transportation.

[0088] In one embodiment of this utility model, please refer to the following: Figure 21The first bracket 14 and the second bracket 15 are rotatably connected by a rotational positioning structure 6. The rotational positioning structure 6 includes two positioning seats that are rotatably arranged opposite each other in a first direction, and a positioning member disposed between the two positioning seats. The two positioning seats are connected to one end of the first bracket 14 and the second bracket 15 respectively. The positioning member is movably arranged and has a positioning position and an avoidance position within its active stroke. In the positioning position, the positioning member cooperates with the two positioning seats to restrict the rotation of the two positioning seats. In the avoidance position, the positioning member disengages from at least one of the positioning seats so that the two positioning seats can rotate relative to each other.

[0089] In one embodiment of this utility model, please refer to the following: Figure 9 and Figure 10 The vehicle 100 also includes two first wheels 71 spaced apart from the frame 1 along a first horizontal direction, and two second wheels 72 spaced apart from the frame 1 along a first horizontal direction. The first wheels 71 and the second wheels 72 are spaced apart along a second horizontal direction. The diameter of the first wheel 71 is smaller than the radius of the second wheel 72, and the width between the two first wheels 71 is smaller than the width between the two second wheels 72. Thus, by setting two first wheels 71 and two second wheels 72, the frame 1 can be stably supported. At the same time, the width between the two first wheels 71 is smaller than the width between the two second wheels 72, so that when the frame 1 is folded, the two first wheels 71 can be placed between the two second wheels 72. The diameter of the first wheel 71 is smaller than the radius of the second wheel 72, so that the height of the two second wheels 72 can be used to hide the two first wheels 71 inside the two second wheels 72. This can improve the space utilization of the wheels and reduce the space occupied by the wheels, thereby helping to reduce the size of the vehicle 100.

[0090] Furthermore, there are various ways to connect the first wheel 71 to the frame 1. The first wheel 71 can be fixedly installed on the frame 1 or detachably installed on the frame 1, etc. This utility model does not limit this. Similarly, there are various ways to connect the second wheel 72 to the frame 1. The second wheel 72 can be fixedly installed on the frame 1 or detachably installed on the frame 1, etc. This utility model does not limit this. Specifically, in this embodiment, the first wheel 71 and / or the second wheel 72 are detachably installed on the frame 1. Thus, the detachable structure facilitates loading and unloading, so that different sizes of wheels can be replaced as needed.

[0091] In one embodiment of this utility model, please refer to Figure 2 and Figure 4When the support structure 2 is in the deployed state, the two support structures 2 are arranged opposite each other to form a passageway 5 between them. This passageway 5 allows passengers to get on and off from the middle of the two support structures 2, enabling them to share vertical space and thus reducing the length of the frame 1, improving its space utilization. Furthermore, the shape of the passageway 5 can vary. For example, the passageway 5 can be of uniform width upwards or gradually widening upwards. This invention does not limit this, but since the width of the passenger increases towards the top, the passageway 5 is often gradually widening upwards to adapt its shape to the passenger's physique, facilitating boarding and alighting.

[0092] In one embodiment of this utility model, a side barrier structure is provided between the two support structures 2. The side barrier structure includes a side barrier member, the two ends of which are respectively connected to the two support structures 2. In this way, by providing the side barrier member, the two support structures 2 located on the first side 111 or the second side 112 are connected to protect the passageway 5, thereby reducing the risk of people falling from the passageway 5.

[0093] Furthermore, there are various types of shielding components. Specifically, in one embodiment, the shielding component includes a shielding rod having a rotatable end and a connecting end. The rotatable end is rotatably mounted on one of the support structures 2 about an axis extending along a first horizontal direction, and the connecting end is detachably mounted on the other support structure 2. Thus, when it is necessary to open the passageway 5, the shielding rod is driven to rotate about the rotatable end so that the connecting end is disengaged from the support structure 2, thereby opening the passageway 5 to facilitate personnel going up and down. When it is necessary to close the passageway 5, the shielding rod is driven to rotate about the rotatable end so that the connecting end is engaged with the support structure 2 to close the passageway 5 and prevent personnel from falling from the passageway 5.

[0094] In another embodiment, the barrier includes two barrier rods, with one end of each barrier rod hinged to one of the two support structures 2 and the other end detachably connected. Thus, when the passageway 5 needs to be opened, the two barrier rods are first separated, and then each barrier rod is driven to rotate around its rotating end to open the passageway 5 for easy access for people. When the passageway 5 needs to be closed, the two barrier rods are driven to rotate around their rotating ends so that the opposite ends of the two barrier rods come closer to each other and connect to close the passageway 5 and prevent people from falling from the passageway 5.

[0095] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
