[0011] In one embodiment, the backrest includes two third links spaced apart along the second horizontal direction, and at least one of the first link and the third link is rotatable toward the inside of the frame;

[0012] The rotation axis of the first link extends in a direction that intersects with the first horizontal direction, and the rotation axis of the third link is set along the first horizontal direction.

[0013] In one embodiment, one of the first link and the second link is provided with a ball portion and the other is provided with a ball groove portion. When the support structure is folded, the first link and the second link can move toward the inside of the frame.

[0014] In one embodiment, one end of the bearing member is rotatably connected to the third link so as to be able to rotate about the axis extending in the first horizontal direction;

[0015] The second connecting rod is provided with a support portion to support the other end of the bearing member when the support structure is in the support position.

[0016] In one embodiment, the backrest further includes a fourth link, the two ends of which are respectively mounted to the ends of the two third links away from the vehicle frame; and / or,

[0018] In one embodiment, the bearing member includes:

[0019] A first plate, one end of which is rotatably connected to the first connecting rod, is capable of rotating about an axis extending in the first horizontal direction; and,

[0020] The second plate has one end rotatably connected to the other end of the first plate so as to be able to rotate about the axis extending in the first horizontal direction, and the other end is used to support the support part when the support structure is in the support position. The second plate can be rotatably folded into one side of the first plate.

[0021] When the support structure is in the folded position, along the second horizontal direction, the bearing member is folded back at the end of the backrest near the second side, and the side panel assembly is folded back at the end of the backrest away from the second side.

[0022] In one embodiment, the vehicle further includes a tie rod assembly, the tie rod assembly comprising:

[0030] The two support structures are respectively located on the first bracket and the second bracket.

[0031] In the technical solution of this utility model, when the vehicle needs to carry passengers, the support member moves to the bearing position so that it can be supported on the support structure, forming a first bearing structure with the support structure, enabling the vehicle to carry passengers. When the vehicle needs to carry goods, the support member moves to the folded position so that it can be folded onto the support structure, allowing the support structure and the support member to surround the perimeter of the frame, forming a second bearing structure with the side frame, enabling the vehicle to carry goods. Thus, by setting up a frame to install the support structure and the support member, and by allowing the support member to move, on the one hand, when the support member is in the bearing position, it can be supported on the support structure, enabling the vehicle to carry passengers; on the other hand, when the support member is in the folded position, the support structure can surround the frame, enabling the vehicle to carry goods. This solves the problem of the existing vehicles having only one function. Attached Figure Description

[0070] 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.

[0071] 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 24A schematic diagram of the structure of the vehicle provided by this utility model.

[0072] Please see Figures 1 to 6 In one embodiment of the present invention, the vehicle 100 includes a frame 1, at least one support structure 2, and a support member 3. The frame 1 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 a backrest 22 disposed on the second side and two side assemblies 21 disposed on the two first sides 111. The support member 3 is connected to the backrest 22 and / or the side assemblies 21. The support member is movable relative to the frame 1. During its movement, the support member 3 has a bearing position and a folded position. In the bearing position, the support member 3 can support the support structure 2 to form a first bearing structure with the support structure 2. In the folded position, the support member 3 can fold into the support structure 2 so that the support structure 2 and the frame 1 form a second bearing structure.

[0073] It is understood 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 varied. 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.

[0074] It should be noted that there are various types of first and second horizontal directions. For example, the first horizontal direction can be the width direction of the frame 1 and the second horizontal direction can be the length direction of the frame 1, or the first horizontal direction can be the length direction of the frame 1 and the second horizontal direction can be the width direction of the frame 1. 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 seat 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 the passengers.

[0075] It should also be noted that the connection of the support member 3 to the backrest 22 and / or the side panel assembly 21 means that the support member can be connected only to the backrest 22, only to the side panel assembly 21, or simultaneously to both the backrest 22 and the side panel assembly 21. The support member 3 can be of various types, including a support plate or a support frame, etc., and this utility model does not limit its application in this regard. Furthermore, the support structure 2 can be fixedly mounted on the frame 1 or movably mounted on the frame 1, and this utility model does not limit its application in this regard either.

[0076] In this invention, when the vehicle 100 needs to carry passengers, the support member 3 moves to the bearing position so that it can be supported on the support structure 2, forming a first bearing structure with the support structure 2, thus enabling the vehicle 100 to carry passengers. When the vehicle 100 needs to carry goods, the support member 3 moves to the folded position so that it can be folded onto the support structure 2, allowing the support structure 2 and the support member 3 to surround the periphery of the frame 1, thus forming a first bearing structure with the side frame 1. The second load-bearing structure enables the vehicle 100 to be used for carrying goods. Thus, by setting up the frame 1, the support structure 2 and the seat 3 can be installed. At the same time, through the movement of the seat 3, on the one hand, when the seat 3 is in the load-bearing position, the seat 3 can be supported on the support structure 2, so that the vehicle 100 can be used for carrying people. On the other hand, when the seat 3 is in the folded position, the support structure 2 can be enclosed on the frame 1, so that the vehicle 100 can be used for carrying goods. This solves the problem of the existing vehicle 100 having only one function.

[0077] Furthermore, the support structure 2 can be fixedly mounted on the frame 1 or movably mounted on the frame 1; this utility model does not limit this. Specifically, in this embodiment, please refer to... Figures 7 to 10 The support structure 2 is movably connected to the frame 1. During its movement, the support structure 2 can be folded up to a position close to the frame 1 and moved away from the frame 1 to a standing support position. The backrest 22 is rotatably connected to the frame 1. Two side panels 21 are connected to the backrest 22 respectively. The side panels 21 can be folded up, and when the side panels 21 are folded up, they can drive the backrest 22 to move, so that the support structure 2 can move to the folded position.

[0078] In this embodiment, when the vehicle 100 needs to support the support member 3, the support structure 2 moves away from the frame 1 to the support position, so that the support structure 2 can stand upright on the frame 1, and the support member 3 can be supported on the support structure 2. When the vehicle 100 does not need to support the support member 3, the support structure 2 is moved to a folded position close to the frame 1, so that the support structure 2 can be folded flat on the frame 1 with the support member 3, so that the support member 3 is set roughly horizontally, which is convenient for carrying goods. In this way, by folding the side panel assembly 21, the backrest 22 is moved, so that the side panel assembly 21 and the backrest 22 can move synchronously. This not only facilitates the switching of the support structure 2 between the support position and the folded position, but also allows the support structure 2 to be folded roughly horizontally on the frame 1, so that the support structure 2 is no longer surrounded on the frame 1, allowing the items to extend out of the frame, which helps to increase the carrying capacity of the vehicle 100.

[0079] In one embodiment of this utility model, please refer to Figures 5 to 10The side panel assembly 21 includes an adjacent first link 211 and a second link 212. The two ends of the second link 212 are hinged to the backrest 22 and one end of the first link 211, respectively. The other end of the first link 211 is rotatably connected to the frame 1. Thus, by setting the first link 211 and the second link 212, the backrest 22 and the frame 1 are connected, so that the side panel assembly 21 can be linked with the backrest 22, thereby facilitating the conversion of the support structure 2 between the supported state and the folded state.

[0080] Please see Figures 10 to 18 The backrest 22 includes two third links 221 spaced apart along the second horizontal direction. At least one of the first link 211 and the third link 221 is rotatable into the frame 11. The extension direction of the rotation axis of the first link 211 is intersecting the first horizontal direction, and the rotation axis of the third link 221 is arranged along the first horizontal direction.

[0081] In this embodiment, when the support structure 2 moves from the supporting position to the folding position, the first link 211 first rotates downward around an axis extending in the first horizontal direction, causing the second link 212 to rotate downward. This causes the connection between the first link 211 and the second link 212 to flip downward, moving the connection between the first link 211 and the second link 212 closer to the connection between the third link 221 and the frame 1. Then, the third link 221 rotates downward around an axis extending in the first horizontal direction, allowing the first link 211 and the second link 212 to move towards the inside of the frame 1 while rotating downward. This allows the first link 211 and the second link 212 to move towards the connection between the third link 221 and the frame 1, so that they can be folded between the third link 221 and the frame 1. It also allows the first link 211 to... The connection point of the first link 211 and the second link 212 is located in the middle of the support area 11 folded into the frame, so that the side panel assembly 21 can be folded into the backrest 22, thereby helping to increase the load capacity of the vehicle 100. Thus, by setting the first link 211 and the second link 212, the side panel assembly 21 and the backrest 22 can move in conjunction, which facilitates the switching of the support structure 2 between the support position and the folded position, thereby making it convenient for the user to change the position of the support structure 2. At the same time, the rotation axis of the first link 211 extends along the first horizontal direction and is intersected in the first horizontal direction, so that the first link 211 can move into the frame 1 while rotating downward, thereby driving the second link 212 to move into the frame 1, so that the side panel assembly 21 can be folded into the backrest 22.

[0082] In one embodiment of this utility model, one of the first link 211 and the second link 212 is provided with a spherical part and the other with a ball groove part. When the support structure 2 is folded, the first link 211 and the second link 212 can move toward the inside of the frame 1. Thus, by providing the mutually cooperating spherical part and ball groove part, the first link 211 and the second link 212 are ball-jointed, which facilitates the switching of the support structure 2 between the folded position and the supported position, and also allows the side panel assembly 21 to move toward the inside of the frame 1 when the support structure 2 is switched to the folded position, so that the side panel assembly 21 can be folded inside the frame 1. Of course, in other embodiments, the second link 212 can also be hinged to the first link 211 or the third link 221 via a joint bearing, as long as it can move toward the inside of the frame under the action of the first link 211 or the third link 212. This utility model does not limit this. Furthermore, the materials of the first link 211, the second link 212, and the third link 221 can be various, including metals such as iron and aluminum, alloys such as steel and aluminum alloys, and inorganic non-metallic materials such as nano-ceramics, as long as they meet the strength requirements. This utility model does not limit the materials used in this regard.

[0083] Furthermore, the first link 211 is bent so that when the support structure 2 is in the supported position, the first link 211 is inclined, with its inclination direction being from bottom to top towards the bearing member 3. This allows the first link 211 to fold towards the frame 1 under the action of the bearing member 3, and also facilitates the boarding and disembarking of passengers on the vehicle 100. Of course, in other embodiments, the first link 211 can also be a straight rod with an inclination, and this utility model does not limit this.

[0084] In order to connect the bearing member 3 to the support structure 2, in one embodiment of this utility model, please refer to... Figures 1 to 6 One end of the bearing member 3 is rotatably connected to the third link 221 so that it can rotate around an axis extending in the first horizontal direction. A support part 2112 is provided on the first link 211 to support the other end of the bearing member 3 when the support structure 2 is in the support position. When the support structure 2 is in the support position, both ends of the bearing member 3 are supported by the first link 211 and the support part 2112 respectively, so that the bearing member 3 can be used to carry people. When the support structure 2 is in the folded position, the bearing member 3 rotates to the horizontal, so that the bearing member 3 can be used to carry goods. Thus, by providing the support part 2112, when the support structure 2 is in the support position, the bearing member 3 rotates to the support part 2112 so that the bearing member 3 can be used to carry people. When the support structure 2 is in the folded position, the bearing member 3 can rotate to the horizontal so that the bearing member 3 can be used to carry goods.

[0085] It should be noted that the support member 3 can move in various ways. In other embodiments, the support member 3 can also be movably installed on the frame 1 in the vertical and horizontal directions, etc., and this utility model does not limit this. In particular, the support part 2112 can be made of various materials. For example, the support part 2112 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, and this utility model does not limit this. Furthermore, the support part 2112 is mainly used to support the support member 3, and its arrangement can be varied. For example, the support part 2112 can be a support block or a support groove, as long as it can support the support member 3, and this utility model does not limit this. Specifically, in this embodiment, the support part 2112 includes a support block that can be detachably installed on the second connecting rod 212. Thus, a support block is used to place the support member 3, and a detachable structure is used to install and remove the support block. Specifically, there are various types of detachable structures, such as screw connection structures or snap-fit ​​connection structures, and this utility model does not limit them.

[0086] In one embodiment of this utility model, please refer to Figure 9 , Figure 11 and Figure 15 The backrest 22 also includes a fourth link 222, with its two ends respectively installed at the ends of the two third links 221 away from the frame 1. By setting the fourth link 214, the two first links 211 are connected, so that the two link assemblies 21 can move synchronously, so as to avoid the user driving the two link assemblies 21 to move separately, thereby helping to improve the user experience.

[0087] In one embodiment of this utility model, please refer to Figure 11 , Figure 13 , Figure 15 and Figure 17 The other end of the support member 2 is separable from the support part 2112 and can be rotatably folded between the two third links 221. When the support structure is in the folded position, the support member 3, the backrest 22, and at least part of the side assembly 21 are folded in the same plane. Thus, the support member 3, the backrest 22, and part of the side assembly 21 are folded in the same plane so that when the support structure 2 is in the folded position, the support structure 2 and the support member 3 can form a plane and be folded on the frame 1 in a generally horizontal manner, thereby facilitating the vehicle 100 to carry goods.

[0088] It should be noted that the above two related technical features: "the backrest 22 also includes a fourth link 222, the two ends of which are respectively installed on the ends of the two third links 221 away from the frame 1" and "the other end of the support member 2 is separable from the support part 2112 and can be rotatably folded between the two third links 221. When the support structure is in the folded position, the support member 3, the backrest 22, and at least part of the side panel assembly 21 are folded in the same plane" can be provided either one or both. This utility model does not limit this.

[0089] In one embodiment of this utility model, when the support structure 2 is in the support position, the support part 2112 is located on the side near the support area 11 where the first connecting rod 211 is hinged to the frame 1. Thus, when someone sits on the seat member 3, the force applied by the seat member 3 will cause the first connecting rod 211 to rotate downwards, bringing the two first connecting rods 211 closer together to clamp and fix the seat member 3 to the frame 1. This interlocks the two first connecting rods 211 with the seat member 3, eliminating the need for an additional locking structure to lock the support structure 2 in the support position. It is understood that the support area 11 is the area formed by the two first sides 111 and the two second sides.

[0090] In one embodiment of this utility model, the support part 2112 is provided in the middle of the first link 211 so that the second link 212 can be located above the support member 3 to form a handrail, so as to define a seating space for people to sit on together with the support member 3. This makes it convenient for people to hold on and reduces the risk of people falling out of the frame 1, thus helping to improve the safety of riding in the vehicle 100.

[0091] Further, please refer to Figures 1 to 5 The support member 3 includes a first plate 31 and a second plate 32. One end of the first plate 31 is rotatably connected to the first connecting rod 211 so as to be able to rotate about an axis extending in the first horizontal direction. One end of the second plate 32 is rotatably connected to the other end of the first plate 31 so as to be able to rotate about an axis extending in the first horizontal direction. The other end is used to support the support part 2112 when the support structure 2 is in the support position. The second plate 32 can be rotatably folded to one side of the first plate 31. When the support structure 2 is in the folded position, along the second horizontal direction, the support member 3 is folded at the end of the backrest 22 near the second side 112, and the side panel assembly 21 is folded at the end of the backrest 22 away from the second side.

[0092] In this embodiment, when the support structure 2 is in the supporting position, both the first plate 31 and the second plate 32 rotate to the horizontal position so that the support member 3 can be supported on the support part 2112. When the support structure 2 is in the folded position, the first plate 31 and the second plate 32 rotate to fold together to reduce the area of ​​the support member 3. Thus, by setting the first plate 31 and the second plate 32, on the one hand, when the support structure 2 is in the supporting position, the area of ​​the support member 3 is guaranteed to facilitate the seating of people. On the other hand, when the support structure 2 is in the folded position, the area of ​​the support member 3 is reduced, which is convenient for storage and can also absorb the height difference of the support structure 2 so that the support member 3 can be kept flush with the support structure 2 for easy loading. At the same time, the support member 3 and the side assembly 21 are respectively located at both ends of the backrest 22, which can make full use of the space of the backrest 22 and support the middle of the backrest 22, which helps to improve the load-bearing capacity of the vehicle 100.

[0093] In order for the bearing member 3 to be rotatably mounted on the third connecting rod 221, in this embodiment, please refer to Figures 1 to 3 The two third connecting rods 221 are provided with two first rotating holes. The bearing member 3 includes a plate and two rotating members 33 provided on the plate. The two rotating members 33 are respectively rotatably installed in the corresponding two first rotating holes. In this way, by setting the first rotating holes and rotating members 33 that cooperate with each other, the plate can be rotatably installed on the first connecting rod 211.

[0094] It should be noted that there are various ways to connect the rotating component 33 to the plate. For example, the rotating component 33 and the plate can be connected by riveting or by screws, etc. This utility model does not limit this. Specifically, in this embodiment, the rotating component 33 is detachably installed on the plate. Thus, a detachable structure is adopted to replace the rotating component 33 as needed, facilitating maintenance or replacement. Furthermore, there are various detachable methods, such as bolt connection or snap-fit ​​connection, etc. This utility model does not limit this.

[0095] 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.

[0096] 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 nano-ceramics. This utility model does not limit these materials.

[0097] 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.

[0098] In one embodiment of this utility model, the frame 1 includes a frame 12 and a storage component 13 disposed within the frame 12. A second load-bearing structure is formed between the support structure 2 and the storage component 13. The storage component 13 is not higher than the lower edge of the frame 12. Thus, by setting the frame 12, the storage component 13 can be installed. By setting the storage component 13, when the support component 3 is in the folded position, the storage component 13 and the support structure 2 can jointly form the second load-bearing structure, facilitating the carrying of goods. When the support component 3 is in the load-bearing position, items can be placed, allowing the vehicle 100 to be used for carrying people and storing goods simultaneously. At the same time, the storage component 13 is not higher than the frame 12, providing clearance for the side panel assembly 21, so that the support structure 2 can be folded approximately horizontally on the frame 1. It is understood that the storage component 13 can be a shelf, a storage cloth, etc., as long as it can hold items. This utility model does not limit this. Furthermore, the statement that the storage component 13 is not higher than the lower edge of the frame 12 means that the storage component 13 can be lower than the lower edge of the frame 12 or flush with the lower edge of the frame 12. This utility model does not limit this.

[0099] In one embodiment of this utility model, please refer to Figure 2 , Figure 4 , Figure 6 and Figure 8Two support structures 2 are provided, facing each other and spaced apart, to define a passageway 5. This passageway 5 allows passengers to board and alight between the two support structures 2, sharing the 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, it 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 typically designed to gradually widen upwards to accommodate the passenger's physique, facilitating boarding and alighting.

[0100] In one embodiment of this utility model, please refer to Figure 19 and Figure 20 The frame 1 includes a first support 14 and a second support 15. The second support 15 is rotatably mounted on the first support 14 about an axis extending in a first horizontal direction. Within its travel range, the second support 15 can rotate to a storage position close to the first support 14 and to a bearing position of the support structure 2. The two support structures 2 are respectively located on the first support 14 and the second support 15. When the frame 1 is in the bearing position, the first support 14 and the second support 15 are flush, 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 support 14 and the second support 15 are close together, so that the frame 1 is in a folded state for storage or transportation. Thus, by rotating the second support 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.

[0101] In one embodiment of this utility model, please refer to Figure 1 , Figure 21 , Figure 23 and Figure 24The frame 1 has two first sides 111 located in a first direction. The vehicle 100 also includes two first mounting arms 62, two second mounting arms 63, and a pivot. The two first mounting arms 62 and the two second mounting arms 63 are respectively mounted on the two first sides 111. Each first mounting arm 62 is provided with a first mounting hole, and each second mounting arm 63 is provided with a second mounting hole. The two ends of the pivot pass through the two first mounting holes and the two second mounting holes, respectively. Thus, by setting two first mounting arms 62 and two second mounting arms 63, two first mounting holes and two second mounting holes are provided. At the same time, by the pivot and the two first mounting holes cooperating with the two second mounting holes, the second bracket 15 can rotate relative to the first bracket 14 around the axis extending in the first horizontal direction. This allows the second bracket 15 to rotate to be flush with the first bracket 14, so that the frame 1 is in a horizontal state, and to rotate to be close to the first bracket 14, so that the frame 1 is in a folded state, so as to reduce the length of the frame 1.

[0102] Furthermore, the two first mounting arms 62 and the two second mounting arms 63 can be positioned in various ways. They can be positioned above or below the vehicle frame 1. This utility model does not limit this. However, since an aisle 5 is formed above the vehicle frame 1, if the two first mounting arms 62 and the two second mounting arms 63 are positioned above the vehicle frame 1, it will affect passengers getting on and off the vehicle frame 1. Therefore, in this embodiment, the two first mounting arms 62 and the two second mounting arms 63 extend downward so that they can avoid the aisle 5 and thus avoid affecting passengers getting on and off the vehicle frame 1.

[0103] It is understandable that the two first mounting arms 62 and the two second mounting arms 63 need to be set in a corresponding manner, that is, the two first mounting arms 62 and the two second mounting arms 63 need to be set under the frame 1 at the same time.

[0104] In one embodiment of this utility model, please refer to Figure 21 and Figure 22The second bracket 1 is provided with a locking hole, and the frame 1 also includes a locking pin 61 movably mounted on the first bracket 14 along a first horizontal direction. During its movement, the locking pin 61 has a locked position passing through the locking hole and an unlocked position disengaged from the locking hole. When the locking pin 61 is in the locked position, the frame 1 is in a bearing position; when the locking pin 61 is in the unlocked position, the frame 1 can rotate to a retracted position. When the first bracket 14 and the second bracket 15 need to be aligned, the locking pin 61 moves along the first horizontal direction to the locked position, with the pin passing through the locking hole to restrict the rotation of the second bracket 15, allowing the first bracket 14 to engage with the second bracket 15. The bracket 15 is kept flush so that the frame 1 is in a horizontal state. When the first bracket 14 and the second bracket 15 need to be stored, the locking pin 61 moves along the first horizontal direction to the unlocked position, with the pin shaft outside the locking hole, so as to release the rotation restriction of the second bracket 15, allowing the second bracket 15 to rotate to the storage position so that the frame 1 is in a folded state. In this way, by setting the locking pin 61 and the locking hole, the relative rotation of the first bracket 14 and the second bracket 15 can be locked or unlocked, so that the frame 1 can be kept in a horizontal state to support the support structure 2, and the frame 1 can be folded into a storage state for convenient storage or transportation.

[0105] In one embodiment of this utility model, the vehicle 100 further 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 the 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 positioned 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, thereby improving the space utilization of the wheels and reducing the space occupied by the wheels, which helps to reduce the size of the vehicle 100.

[0106] 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.

[0107] 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.
