[0073] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0074] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0075] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0076] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0077] Currently, push-pull powered vehicles on the market, such as carts and trailers, are typically equipped with seating or cargo structures, allowing them to carry either people or cargo. However, these vehicles are typically limited to carrying only people or cargo, resulting in limited functionality that fails to meet user needs.

[0078] Based on this, the present invention proposes a vehicle that aims to solve the problem of single function of existing vehicles. Figures 1 to 24 This is a schematic structural diagram of the carrier provided by the present invention.

[0079] See also Figure 1 and Figure 15 In one embodiment of the present invention, the vehicle 100 includes a frame 1 and two seat assemblies, the two seat assemblies are spaced apart from the frame 1, and at least one seat assembly is configured as a movable seat assembly, which is movably mounted on the frame 1. During its movable travel, the movable seat assembly can move toward the frame 1 to a folded state, and move away from the frame 1 to an upright support state.

[0080] It should be noted that the frame 1 is primarily used to bear loads and requires a certain degree of hardness and strength. It can be made of a variety of materials. 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, and the present invention is not limited thereto. Similarly, the seat member 3 can be made of a variety of 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 they meet the strength requirements. The present invention is not limited thereto.

[0081] In the technical solution of the present invention, when the vehicle 100 needs to carry people, the movable seat assembly moves in a direction away from the frame 1 to stand up to form a supporting state, so that the vehicle 100 can carry people. When the vehicle 100 needs to carry objects, the movable seat moves in a direction close to the frame 1 to form a folded state, so that the vehicle 100 can carry objects. When the vehicle needs to carry both people and objects, one of the two seat assemblies is used to carry people, and the other seat assembly moves to a folded state for carrying objects. In this way, by setting the frame 1, the seat assembly can be set, and at the same time, through the movement of the movable seat assembly, the movable seat assembly can be used for both carrying people and carrying objects, so that the two seat assemblies can carry people and objects at the same time, thereby solving the problem of the single function of the existing vehicle 100.

[0082] In order to enable the movable seat assembly to form a folded state and a supported state, in one embodiment of the present invention, please refer to Figures 1 to 10 The frame 1 is formed with a support area 11, and the movable seat assembly includes a support structure 2 and a seat member 3. The support structure 2 is movably connected to the frame 1 and has a folding position and a supporting position in its movable range. When in the folding position, the support structure 2 is movably stored in the support area 11, so that the movable seat assembly is in a folded state. When in the supporting position, the support structure 2 moves in a direction away from the support area 11 to stand up, so that the movable seat is in a supporting state. The seat member 3 that can move relative to the frame 1 is used to support the support structure 2 when the support structure 2 is in the supporting position.

[0083] In this embodiment, when the carrier 100 needs to carry people, the support structure 2 moves away from the support area 11 to the support position, so that the seat member 3 can be supported on the support structure 2, so that the carrier 100 can be used to carry people. When the carrier 100 needs to carry objects, the support structure 2 is moved and stored in the support area 11, so that the support structure 2 can be folded flush with the seat member 3 on the vehicle frame 1, so that the carrier 100 can be used to carry objects. In this way, by setting the support structure 2 and the seat member 3, on the one hand, when the support structure 2 is in the supporting position, the support structure 2 can support the seat member 3, so that the carrier 100 can be used to carry people. On the other hand, when the support structure 2 is in the storage position, the support structure 2 can be folded flush with the seat member 3 on the vehicle frame 1, so that the carrier 100 can be used to carry objects, and can also be stored in the support area 11 to support the seat member 3, so that the seat member 3 can withstand a larger load, which is beneficial to increase the carrying capacity of the carrier 100. It should be noted that, please refer to Figure 1 and Figure 7 The support area 11 refers to an area within the vehicle frame 1 and is surrounded by two first side edges 111 and two second side edges 112 .

[0084] Furthermore, the support area 11 has two first side edges 111 located in the first horizontal direction and two second side edges 112 located in the second direction. The support structure 2 includes at least one side panel assembly 22 arranged on the first side edge 111 and a backrest 21 arranged on at least one second side edge 112. The side panel assembly 22 is connected to the backrest 21. When the side panel assembly 22 is folded toward the frame 1, the backrest 21 can be driven to move closer to the frame 1. In this way, the backrest 21 and the side panel assembly 22 are arranged so as to be surrounded by the frame 1 to reduce the risk of people falling. At the same time, the backrest 21 is connected to the frame 1 through the side panel assembly 22, so that the backrest 21 can be linked with the side panel assembly 22, so that the backrest 21 can be folded synchronously when the side panel assembly 22 is folded.

[0085] It should be noted that there are various possibilities for the first horizontal direction and the second horizontal direction. For example, the first horizontal direction may be the width direction of the frame 1 and the second horizontal direction may be the length direction of the frame 1, or the first horizontal direction may be the length direction of the frame 1 and the second horizontal direction may be the width direction of the frame 1. The present invention is not limited to 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 length direction of the frame 1. When the vehicle 100 is carrying a passenger, the passenger's orientation is aligned with the direction of movement of the vehicle 100, thereby facilitating improved passenger comfort.

[0086] In one embodiment of the present invention, see Figure 9 、 Figure 10 、 Figure 21 and Figure 22 In the folded state, the support structure 2 is stored in the support area 11 and is arranged flush with it. In this way, the support structure 2 is arranged substantially horizontally, so that when the support structure 2 is folded onto the vehicle frame 1, the vehicle 100 can be used to carry objects. It is understood that the support structure 2 being arranged flush means that the support structure 2 can be folded substantially horizontally onto the vehicle frame 1, so that the support structure 2 can be used to carry objects.

[0087] It should be noted that the above two related technical features: "The support structure 2 includes at least one side panel assembly 22 arranged on the first side edge 111 and a backrest 21 arranged on at least one second side edge 112, the side panel assembly 22 is connected to the backrest 21, and when the side panel assembly 22 is folded toward the frame 1, it can drive the backrest 21 to move closer to the frame 1", "In the folded state, the support structure 2 is stored in the support area 11 and is arranged flush", can be set either one or both, and the present invention does not limit this.

[0088] In one embodiment of the present invention, please refer to Figure 1 、 Figure 2 、 Figure 15 and Figure 16The backrest 21 includes two first connecting rods 211 arranged at intervals along the first horizontal direction, and two side panel assemblies 22 are provided. The two side panel assemblies 22 are respectively connected to the two first connecting rods 211 and are respectively folded on one side of the corresponding first connecting rod 221. In this way, by providing two first connecting rods 211, which are respectively connected to the two side panel assemblies 22, the two side panel assemblies 22 can be linked with the backrest 21 so that the two side panels 22 can move synchronously with the backrest 21, so that the support structure 2 can switch between the folded position and the supporting position, and the support structure 2 can be surrounded on the vehicle 1 when in the supporting position to enclose the surrounding side of the frame 1 and reduce the risk of people falling.

[0089] In one embodiment of the present invention, see Figures 1 to 4 、 Figure 15 and Figure 16 The vehicle also includes a seat member 3, which is coupled to the support structure 2 to form a bearing space on the support structure 2. In this way, by providing the seat member 3, a seating space can be formed for people to sit in, and it can also be linked with the support structure 2 so that when the support structure 2 is supported on the frame 1, it can be supported on the support structure 2, so that the vehicle 100 can be used to carry people, and when the support structure 2 is folded on the frame 1, it can be folded on the frame 1, so that the vehicle can be used to carry objects. Of course, in other embodiments, the seat member 3 can also be directly provided on the frame 1, etc., and the present invention does not limit this. It can be understood that the seat member 3 can be a seat plate, or a seat frame, etc., and the present invention does not limit this.

[0090] It should be noted that the above two related technical features: "The backrest 21 includes two first connecting rods 211 arranged at intervals along the first horizontal direction, and two side panel assemblies 22 are provided, and the two side panel assemblies 22 are respectively connected to the two first connecting rods 211, and are respectively folded on one side of the corresponding first connecting rod 221", and "The carrier also includes a seat member 3, which is engaged with the support structure 2 to form a bearing space on the support structure 2". Either one of them can be set, or they can be set at the same time, and the present invention does not limit this.

[0091] In one embodiment of the present invention, see Figures 5 to 8The side panel assembly 22 includes a second link 221 and a third link 222. The first link 221 and the second link 222 are spaced apart in the second horizontal direction on a first side edge 111, and one end of the first link 211 and the second link 221 are both rotatably connected to the frame 1, and both ends of the third link 222 are hinged to one end of the first link 211 and the second link 221. At least one of the first link 221 and the third link 222 can rotate toward the supporting area 11. When the support structure 2 moves from the supporting position to the folded position, the second link 221 first rotates downward around a rotation axis, so that the third link 222 rotates downward, thereby driving the connection between the second link 221 and the third link 222 to flip downward, so that the connection between the second link 221 and the third link 222 is close to the connection between the first link 211 and the frame 1. The first link 211 is movable, and then the first link 211 is rotated downward around the axis extending along the first horizontal direction, so that the second link 221 and the third link 222 are movable toward the middle of the support area 11 while rotating downward, so that the second link 221 and the third link 222 can move toward the connection between the first link 211 and the frame 1 so as to be folded on the inner side of the first link 211 and the frame 1, and can also make the connection between the two second links 221 and the third link 222 close to each other in the middle of the support area 11, so that the support structure 2 can support the seat member 3, thereby helping to increase the load capacity of the vehicle 100. In this way, by arranging the second link 221 and the third link 222, the side panel assembly 22 and the backrest 21 can be linked and moved, so that the support structure 2 can be switched between the support position and the folded position, thereby making it convenient for the user to change the position of the support structure 2.

[0092] Furthermore, the second connecting rod 221 can be arranged in a variety of ways. Specifically, in this embodiment, when the support structure 2 is in the supporting position, the second connecting rod 221 is arranged at an angle, with its inclination direction tilting from bottom to top toward the side of the support member 3, thereby clamping the support member 3 and facilitating passengers to get on and off the vehicle 100. Of course, in other embodiments, the second connecting rod 221 can also be arranged vertically, and the present invention is not limited to this. It is understood that the second connecting rod 221 can be a straight rod, a curved rod, etc., and the present invention is not limited to this.

[0093] It is understood that there are various ways to connect the third connecting rod 222 to the first connecting rod 211 or the second connecting rod 221. For example, the third connecting rod 222 can be hinged to the first connecting rod 211 or the second connecting rod 221 via a ball joint, or the third connecting rod 222 can be hinged to the first connecting rod 211 or the second connecting rod 221 via a joint bearing, etc. As long as it can move toward the middle of the support area 11 under the drive of the first connecting rod 211 or the second connecting rod 221, the present invention does not limit this. Furthermore, the first connecting rod 211, the second connecting rod 221, and the third connecting rod 222 can be made of a variety of materials, including metal materials such as iron and aluminum, alloy materials such as steel and aluminum alloy, and inorganic non-metallic materials such as ceramics. As long as they can meet the strength requirements, the present invention does not limit this.

[0094] In order to enable the side panel assembly 22 to rotate toward the middle of the support area 11, in this embodiment, refer to Figures 7 to 10 The rotation axis of the first link 211 is arranged along the first horizontal direction, and the extension direction of the rotation axis of the second link 221 is arranged to intersect with the first horizontal direction. In this way, the rotation axis of the first link 211 is arranged along the first horizontal direction, so that the first link 211 can be folded on the first side 111 of the frame 1. The rotation axis of the second link 221 extends along the first horizontal direction and is arranged to intersect with the first horizontal direction, so that the second link 221 can move toward the middle of the support area 11, thereby driving the third link 222 to move toward the middle of the support area 11, thereby allowing the support structure 2 to move toward the support area 11. Of course, in other embodiments, the rotation axes of the first link 211 and the second link 221 are both arranged parallel to the first horizontal direction, and the present invention is not limited to this. However, such an arrangement will cause the support member 3 to have a certain degree of inclination, which will affect the loading of the carrier 100.

[0095] In another embodiment of the present invention, see Figures 15 to 29The side panel assembly 22 includes a second link 221 and a third link 222. The first link 221 and the second link 222 are spaced apart in the second horizontal direction on a first side edge 111. One end of each of the first link 211 and the second link 221 is pivotally connected to the vehicle frame 1. Both ends of the third link 222 are hinged to one end of each of the first link 211 and the second link 221. The second link 221 and the third link 222 are pivotally connected about a first axis via a pivot connection structure 24, forming a linkage structure with the first link 211 and the vehicle frame 1. A locking structure is provided at at least one connection point of the linkage structure for locking or unlocking the linkage structure. The first axis extends along the first horizontal direction. When the carrier 100 needs to carry people, the locking structure 23 first moves to the unlocked state to release the lock on the linkage structure, so that the support structure 2 can move to the supporting position away from the support area 11, and then the locking structure 23 moves to the locked position to lock the linkage structure, so that the support structure 2 can remain in the supporting position to support the seat member 3, so that the carrier 100 can be used to carry people. When the carrier 100 needs to carry objects, the locking structure 23 first moves to the unlocked state to release the lock on the linkage structure, so that the support structure 2 can move to the folded position close to the support area 11, and then the locking structure 23 moves to the locked position to lock the linkage structure, so that the support structure 2 can remain in the folded state, so that the carrier 100 can be used to carry objects. In this way, by providing the second link 221 and the third link 222 to connect the first link 211 and the frame 1, the first link 211, the second link 221, the third link 222 and the frame 1 form a linkage structure, so that the support structure 2 can be maintained in a supporting state or a folded state, so that when the support structure 2 is in the supporting state, the support structure 2 can support the seat member 3, so that the vehicle 100 can be used to carry people, and when the support structure 2 is in the folded state, the support structure 2 and the seat member 3 can be folded flush on the frame 1, so that the vehicle 100 can be used to carry objects.

[0096] It should be noted that there are multiple ways to rotate the second link 221 and the third link 222. In one embodiment, when the movable seat assembly is switched to the folded state, the second link 221 and the third link 222 can rotate inward along the first horizontal axis to move the connection between the second link 221 and the third link 222 toward the connection between the first link 211 and the frame 1, so that the second link 221 and the third link 222 can be folded inside the first link 211 and the frame 1, so as to reduce the folded side panel assembly 22 on the frame. 1 lengthwise dimension. Of course, in another embodiment, when the movable seat assembly is switched to the folded state, the second link 221 and the third link 222 can rotate outward along the first horizontally extending axis, so that the connection between the second link 221 and the third link 222 moves in a direction away from the connection between the first link 211 and the frame 1, so that the second link 221 and the third link 222 can be folded outside the first link 211 and the frame 1. However, this method will increase the lengthwise dimension of the side panel assembly 22 after folding, which is not conducive to storage.

[0097] In one embodiment of the present invention, see Figures 17 to 22 The seat member 3 is connected to the side panel assembly 22 and / or the backrest 21 so that when the support structure 2 is folded, the seat member 3 is driven to fold, so that the seat member 3 can be linked with the support structure 2 so that when the support structure 2 is in the folded position, the seat member 3 can be synchronously folded onto the vehicle frame 1. It is understood that the seat member 3 is connected to the side panel assembly 22 and / or the backrest 21, which means that the seat member can be connected to the side panel assembly 22, the backrest 21, or both. In addition, the seat member 3 can be movably connected or detachably connected, which is not limited in the present invention.

[0098] In one embodiment of the present invention, please refer to Figure 9 、 Figure 21 and Figure 23 When the support structure is in the folded position, the side panel assemblies 22 and / or the seat member 3 are folded between the two first connecting rods 211. Thus, folding the side panel assemblies 22 and the seat member 3 between the two first connecting rods not only enables the side panel assemblies 21 to support the middle portion of the backrest, but also helps improve the load-bearing capacity of the support structure 2, allowing the folded support structure 2 to support heavier items. Furthermore, it allows the support structure 2 to be folded into a smaller size for easier storage. Of course, in other embodiments, the side panel assemblies 2 and the seat member 3 may also be folded outside the two first connecting rods, and the present invention is not limited thereto.

[0099] In one embodiment of the present invention, see Figure 9The support member 3 is rotatably connected to the backrest 21. When the support structure 2 is in the folded position, the support member 3, the backrest 21, and at least part of the side panel assembly 22 are folded in the same plane, and in the second horizontal direction, the support member 3 is folded at the end of the backrest 21 close to the second side edge 112, and the side panel assembly 22 is folded at the end of the backrest 21 away from the second side edge 111. In this way, the support member 3, the backrest 21 and part of the side panel assembly 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 roughly horizontally on the frame 1, thereby facilitating the carrier 100 to carry objects. At the same time, the support member 3 and the side panel assembly 22 are respectively arranged at both ends of the backrest 21, which can fully utilize the space of the backrest 21 and support the middle part of the backrest 21, thereby helping to improve the carrying capacity of the carrier 100.

[0100] In another embodiment of the present invention, see Figure 21 and Figure 23 One end of the seat member 3 is connected to the backrest 21, and the other end is movably connected to the side panel assembly 22. When the support structure 2 is in the folded position, the seat member 3, the backrest 21 and the side panel assembly 22 are all folded in the same plane, and the side panel assembly 22 is located between the seat member 3 and the first connecting rod 211. In this way, the seat member 3, the backrest 21 and part of the side panel assembly are folded in the same plane, so that when the support structure 2 is in the folded position, the support structure 2 and the seat member 3 can form a plane and be folded roughly horizontally on the frame 1, thereby facilitating the carrier 100 to carry objects. At the same time, the side panel assembly 22 is folded between the seat member 3 and the backrest 21, so that the backrest 21 can be folded beside the side panel assembly 21, so as to make full use of the space of the backrest 21 for folding, thereby improving the space utilization rate of the support structure.

[0101] In order to connect the seat member 3 to the support structure 2, in one embodiment of the present invention, see Figures 15 to 21 One end of the support member 3 is hinged to the backrest 21, and the other end is hinged to the side panel assembly 22 via a connecting rod 225. In this way, when the side panel assembly 22 is supported on the vehicle frame 1, the support member 3 can be supported on the support structure 2 to carry people. When the side panel assembly 22 is folded into the vehicle frame 1, the support member 3 can be placed roughly horizontally on the vehicle frame 1 to carry objects. It is understood that the support member 3 can be a support plate, a support frame, etc., and the present invention is not limited to this. Furthermore, 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 connecting rod 222, and the other end is connected to the second connecting rod 221 in a second horizontal direction. In this way, when the support structure 2 switches between the supporting 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 vehicle frame 1 to carry objects.

[0102] In one embodiment of the invention, the backrest 21 also includes a fourth connecting rod 212 to form a frame with the two first connecting rods 211, and when the support structure 2 is in a folded state, the side frame assembly 22 and / or the seat member 3 are folded in the frame. In this way, by setting the fourth connecting rod 212, the two side frame assemblies 22 can be connected so that the two side frame assemblies 22 can be linked and the two side frame assemblies 22 can move synchronously, so as to avoid the user driving the two side frame assemblies 22 to move separately, which is convenient for the user to switch the state of the support structure 2, and the second connecting rod 221 and the second connecting rod 222 can be folded in the frame so that the side frame assemblies 22 can support the frame, which helps to improve the load-bearing capacity of the support structure 2, so that the support structure 2 in the folded state can support heavier items.

[0103] It should be noted that the above two related technical features: "One end of the seat member 3 is hinged to the backrest 21, and the other end is hinged to the side panel assembly 22 through the connecting rod 225", "The backrest 21 also includes a fourth connecting rod 212 to form a frame with the two first connecting rods 211, and when the support structure 2 is in a folded state, the side panel assembly 22 and / or the seat member 3 are folded in the frame" can be set selectively or simultaneously, and the present invention does not limit this.

[0104] In order to connect the seat member 3 to the support structure, in another embodiment of the present invention, see Figures 1 to 6 One end of the seat member 3 is rotatably connected to the first connecting rod 211 so as to be able to rotate around an axis extending in the first horizontal direction. A support portion 2211 is provided on the second connecting rod 221 to support the other end of the seat member 3 when the support structure 2 is in the supporting position. When the support structure 2 is in the supporting position, both ends of the seat member 3 are respectively supported on the first connecting rod 211 and the support portion 2211, so that the seat member 3 can be used for carrying people. When the support structure 2 is in the folded position, the seat member 3 rotates to the horizontal position so that the seat member 3 can be used for carrying objects. In this way, by providing the support portion 2211, when the support structure 2 is in the supporting position, the seat member 3 rotates to the support portion 2211 so that the seat member 3 can be used for carrying people. When the support structure 2 is in the folded position, the seat member 3 can rotate to the horizontal position so that the seat member 3 can be used for carrying objects.

[0105] It should be noted that the seat member 3 can be moved in a variety of ways. In other embodiments, the seat member 3 can also be mounted on the vehicle frame 1 in a vertical and horizontal direction, etc., and the present invention does not limit this. Furthermore, the seat member 3 can be of various types, for example, it can be a seat plate, it can also be a seat frame, etc., as long as it can accommodate people, the present invention does not limit this. The seat member 3 can be an integrated setting or a split setting. In one embodiment, please refer to Figures 1 to 4The support member 3 includes two seat plates that are movably connected and can be folded. When the support structure 2 is converted to the folded state, the support member 3 is first folded and then rotated to be close to the backrest. Similarly, the support portion 2211 can be made of a variety of materials. For example, the support portion 2211 can be made of metal materials such as iron and aluminum, or alloy materials such as steel and aluminum alloy, or inorganic non-metallic materials such as ceramics, but the present invention does not limit this. Furthermore, the support portion 2211 is mainly used to support the support member 3. There are many ways to set it up. For example, the support portion 2211 can be a support block or a support groove, etc., as long as it can support the support member 3, the present invention does not limit this. Specifically, in this embodiment, the support portion 2211 includes a support block that is detachably mounted on the second connecting rod 221. In this way, the support block is used to facilitate the placement of the support member 3, and a detachable structure is used to facilitate the installation and removal of the support block. Specifically, there are many detachable structures, which can be a screw connection structure or a snap connection structure, etc., but the present invention does not limit this.

[0106] In one embodiment of the present invention, see Figure 3 When the support structure 2 is in the supporting position, the support portion 2211 is located on the side of the hinged connection between the second link 221 and the frame 1, near the support area 11. Thus, when someone sits on the seat 3, the force exerted by the seat 3 causes the second link 221 to rotate downward, bringing the two second links 221 closer together, thereby clamping the seat 3 to the frame 1 and interlocking the two second links 221 with the seat 3, eliminating the need for an additional locking structure to lock the support structure 2 in the supporting position. Furthermore, the support portion 2211 is located in the middle of the second link 221, allowing the third link 222 to be located above the seat 3, thereby forming an armrest. This allows the seat 3 to define a passenger space for passengers, making it easier for passengers to hold onto the seat while reducing the risk of passengers falling off the frame 1, thereby improving the safety of the vehicle 100.

[0107] Further, see Figures 2 to 7The 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 around 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 around an axis extending in the first horizontal direction. The other end is used to support the support structure 2 when it is in the supporting position and is supported on the support portion 2211. When the support structure 2 is in the supporting position, the first plate 31 and the second plate 32 are both rotated to the horizontal so that the support member 3 can be supported on the support Support portion 2211, when the supporting structure 2 is in the folded position, the first plate body 31 and the second plate body 32 are rotated to fold together so as to reduce the area of ​​the seat member 3. In this way, by setting the first plate body 31 and the second plate body 32, on the one hand, when the supporting structure 2 is in the supporting position, the area of ​​the seat member 3 is guaranteed to facilitate people to sit on. On the other hand, when the supporting structure 2 is in the folded position, the area of ​​the seat member 3 is reduced, which is convenient for storage and can absorb the height difference of the supporting structure 2, so that the seat member 3 can be kept flush with the supporting structure 2, which is convenient for loading.

[0108] In order to enable the support member 3 to be rotatably mounted on the first connecting rod 211, in this embodiment, please refer to Figure 1 The two first connecting rods 211 are provided with two first rotating holes. The supporting member 3 includes a plate body and two rotating members 33 provided on the plate body. 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 the rotating members 33 that cooperate with each other, the plate body can be rotatably installed on the first connecting rod 211.

[0109] It should be noted that there are various ways to connect the rotating member 33 to the plate. For example, the rotating member 33 and the plate can be connected by riveting or screws, etc., which is not limited in the present invention. Specifically, in this embodiment, the rotating member 33 is detachably mounted on the plate. In this way, the detachable structure allows the rotating member 33 to be replaced as needed, facilitating maintenance or replacement. Furthermore, there are various detachable methods, such as bolt connection and snap connection, which are not limited in the present invention.

[0110] In one embodiment of the present invention, see Figures 28 to 32The rotating connection structure 24 includes two mounting seats 241 that are relatively and rotatably arranged in the first direction. The two mounting seats 241 are correspondingly connected to one end of the first connecting rod 211 and the second connecting rod 221. The locking structure 23 includes a locking member 231. The locking member 231 is movably arranged between the two mounting seats 241 and has a locking position and an unlocking position. When the locking member 231 is in the locking position, it cooperates with the two mounting seats 241 to limit the rotation of the two mounting seats 241. When the locking member 231 is in the unlocking position, it is released from the cooperation with at least one of the mounting seats 241 so that the two mounting seats 241 can rotate relative to each other. When the first connecting rod 211 and the second connecting rod 221 need to be locked, the locking member 231 moves to the locking position. At this time, the locking member 231 is between the two mounting seats 241 to cooperate with the two mounting seats The seats 241 cooperate to limit the rotation of the two mounting seats 241, thereby locking the first link 211 and the second link 221. When the first link 211 and the second link 221 need to be rotated, the locking member 231 moves to the unlocked position. At this time, the locking member 231 can release the rotation restriction of the two mounting seats 241, so that the first link 211 and the second link 221 can rotate relative to each other. In this way, by providing the mounting seats 241 and the locking member 231 that cooperate with each other, the locking member 231 can not only limit the rotation of the two mounting seats 241 and prevent the two mounting seats 241 from rotating relative to each other, but also release the rotation restriction of the two mounting seats 241, so that the first link 211 and the second link 221 can rotate relative to each other, thereby enabling the support structure 2 to switch between the folded state and the supported state.

[0111] Further, see Figure 30 and Figure 31 The locking member 231 is movably arranged on one of the mounting seats 241 along the first direction, so that the moving direction of the locking member 231 is consistent with the rotation axis of the first connecting rod 211 or the second connecting rod 221, thereby facilitating the locking member 231 to switch between the locked position and the unlocked position.

[0112] In one embodiment of the present invention, see Figure 30 and Figure 33 A limited matching structure 233 is provided between the locking member 231 and each mounting seat 241. The limited matching structure 233 includes a limiting portion and a matching portion. One of the limiting portion and the matching portion is provided on the locking member 231, and the other is provided on the mounting seat 241. The limiting portion and / or the matching portion are provided in multiple numbers along the circumference of the rotating shaft of the mounting seat 241. In this way, by providing the limiting portion and the matching portion that match each other, after the two mounting seats 241 are rotated to the corresponding positions, the two mounting seats 241 are locked to limit the relative rotation of the two mounting seats 241, so that the support structure 2 can maintain the current state.

[0113] It should be noted that in order to be able to lock the two mounting seats 241 at different angles so that the rotation angles of the second connecting rod 221 and the third connecting rod 222 are adjustable, there are multiple ways to set the limiting portion and the matching portion. It can be that multiple ones of one of them are set and one of the other is set, or multiple ones of both are set, so that one of the limiting portion and the matching portion can be selected to match the other one with a different setting, so that the two mounting seats 241 can be locked at different angles.

[0114] Furthermore, one of the limiting portion and the mating portion is a limiting protrusion 2331, and the other is a mating groove. Thus, by providing the mutually mating limiting protrusion 2331 and the mating groove, the rotation between the locking member 231 and the mounting seat 241 is restricted. It is understood that there are various limiting and mating structures 233. In other embodiments, the limiting and mating structure 233 can also be limited by a magnetic connection structure, etc., and the present invention is not limited to this.

[0115] To drive the locking member 231, see Figure 31 In this embodiment, at least one of the mounting seats 241 is provided with a driving member 232 for driving the locking member 231 to move between a locked position and an unlocked position. Thus, by providing the driving member 232 to drive the locking member 231 to move, the locking member 231 can be switched between the locked position and the unlocked position. Furthermore, the driving member 232 can be of various types, such as a button or a cylinder, and the present invention is not limited thereto. Specifically, in this embodiment, the driving member 232 is a driving button, so that the user can manually operate the locking member 231 to move, which helps reduce both the weight and the cost of the support structure 2. It is understood that the driving member 232 can be made of various materials, such as metal materials such as iron and steel, inorganic non-metallic materials such as ceramics, and polymer materials such as plastic, and the present invention is not limited thereto.

[0116] In one embodiment of the present invention, at least one of the mounting seats 241 is provided with an elastic member. The elastic member is positioned between the corresponding mounting seat 241 and the locking member 231 to reset the locking member 231 to the locked position. The provision of the elastic member allows the locking member 231 to remain in the locked position, thereby reducing the frequency of operation of the locking member 231 and improving the user experience. It is understood that the elastic member can be a spring, rubber, or the like, and this is not limited in the present invention. Furthermore, the locking member 231 is provided with an annular groove 2311 for mounting the elastic member.

[0117] In order to facilitate the installation of the locking member 231, in this embodiment, each mounting seat 241 is provided with a docking groove, and the two mounting grooves are docked to form an installation cavity, and the locking member 231 is arranged in the installation cavity. In this way, by providing the docking groove to form the installation cavity, the locking member 231 can be hidden in the installation cavity, which can prevent the locking member 231 from being affected by external factors and protect the locking member 231, and can also improve the appearance of the carrier 100.

[0118] To connect the two mounting blocks 241, in this embodiment, each mounting block 241 is provided with a through-hole. The side panel assembly 22 also includes a connector that passes through the two through-holes to connect the two mounting blocks 241. Thus, the through-holes and connectors facilitate the connection of the two mounting blocks 241. Furthermore, a mounting boss extending along a first horizontal direction is provided in the middle of each mounting block 241. The through-hole is provided in the mounting boss. When the two mounting blocks 241 are connected, the two mounting bosses abut, connecting the two through-holes to facilitate the insertion of the connector. The locking member 231 is sleeved onto the mounting boss. Furthermore, the locking member 231 can be rotatably mounted on the mounting boss or fixedly mounted on the mounting boss, although this is not limited in the present invention. Specifically, in this embodiment, the locking member 231 is fixedly mounted on the mounting boss to restrict rotation between the locking member 231 and the mounting boss, thereby enhancing the locking effect of the locking member 231.

[0119] In one embodiment of the present invention, see Figure 32 、 Figure 34 、 Figure 35 and Figure 36 The locking structure 23 also includes a rotation limiting structure 25 provided between the backrest 21 and / or the side panel assembly 22 and the frame 1. The rotation limiting structure 25 includes a limiting rib 251 and a limiting groove 252 provided on the frame 1 and the frame 1 respectively. The limiting groove 252 extends along its circumference. The limiting rib 251 cooperates with the limiting groove 252 to limit the movable stroke of the backrest and the side panel assembly.

[0120] In one embodiment of the present invention, the vehicle 100 also includes a pull rod assembly 4, which includes a sleeve 41 and a pull rod 42. The sleeve 41 is provided on the frame 1, and the pull rod 42 is movably installed on the sleeve 41 along the axial direction of the sleeve 41. When the vehicle 100 needs to be towed, the pull rod 42 is pulled out of the sleeve 41 so that personnel or a towing mechanism can tow the vehicle 100. When the vehicle 100 does not need to be towed, the pull rod 42 is hidden in the sleeve 41 to avoid collision, which helps to increase the safety of the vehicle 100. In this way, by providing the sleeve 41 to accommodate the pull rod 42 and through the movement of the pull rod 42, it is convenient to tow the vehicle 100, increase the safety of the vehicle 100, and improve the appearance of the vehicle 100.

[0121] It should be noted that the sleeve 41 and the pull rod 42 can have various shapes, for example, they can be cylindrical structures or prismatic structures, etc., and the present invention does not limit this. Furthermore, the sleeve 41 and the pull rod 42 can be made of various materials, such as metal materials such as iron and aluminum, alloy materials such as steel and aluminum alloy, and inorganic non-metallic materials such as ceramics, and the present invention does not limit this.

[0122] Furthermore, the sleeve 41 can be fixedly installed on the frame 1 or movably installed on the frame 1, etc., and the present invention does not limit this. However, for different personnel or traction mechanisms, its height will also be different, resulting in different inclination angles of the pull rod 42. For this reason, in this embodiment, the sleeve 41 is rotatably installed on the frame 1 around an axis extending in the first horizontal direction. In this way, the sleeve 41 adopts a rotatable setting so that the inclination angle of the pull rod 42 can be adapted to the traction height of the personnel or traction mechanism, thereby facilitating the personnel or traction mechanism to tow the vehicle 100.

[0123] In one embodiment of the present invention, the vehicle frame 1 includes a frame 12 and a storage member 13 disposed within the frame 12. Thus, the frame 12 is provided to accommodate the storage member 13, and the storage member 13 is provided so that the vehicle 100 can be used to store items while carrying a person. It is understood that the storage member 13 can be a storage plate, a storage cloth, or the like, as long as it can accommodate items, and the present invention is not limited thereto.

[0124] In one embodiment of the present invention, both seat assemblies are movable seat assemblies. When the movable seat assemblies are in a supporting state, the two movable seat assemblies are arranged relative to each other and at a distance to define an aisle 5. In this way, by setting the aisle 5, passengers can get on and off from the middle of the two seat assemblies, so that the upper and lower spaces of the two movable seat assemblies can be shared, thereby reducing the length of the frame 1 and helping to improve the space utilization of the frame 1.

[0125] Furthermore, the shape of the aisle 5 is varied. For example, the aisle 5 may be arranged to have a uniform width upwards, or may be arranged to gradually expand upwards. The present invention does not limit this. However, since the width for passengers increases upwards, the aisle 5 may be arranged to gradually expand upwards so that the shape of the aisle 5 can be adapted to the body shape of the passengers, thereby facilitating passengers to get on and off.

[0126] In one embodiment of the present invention, a side block structure is provided between the two support structures 2, and the side block structure includes a side block member, and its two ends are respectively connected to the two support structures 2. In this way, by providing the side block member, the two support structures 2 on the first side 111 or the second side 112 are connected to enclose the aisle 5, thereby reducing the risk of people falling from the aisle 5.

[0127] Furthermore, there are multiple types of shielding members. Specifically, in one embodiment, the shielding member includes a shielding rod, which has a relatively rotating end and a connecting end. The rotating end is rotatably installed on one of the supporting structures 2 around an axis extending along the first horizontal direction, and the connecting end is detachably installed on the other supporting structure 2. In this way, when it is necessary to open the aisle 5, the shielding rod is driven to rotate around the rotating end to disengage the connecting end from the supporting structure 2, so as to open the aisle 5 and facilitate people to go up and down. When it is necessary to close the aisle 5, the shielding rod is driven to rotate around the rotating end to combine the connecting end with the supporting structure 2 to close the aisle 5 and prevent people from falling from the aisle 5.

[0128] In another embodiment, the shielding member includes two shielding rods, the opposite ends of the two shielding rods are respectively hinged to the two supporting structures 2, and the opposite ends can be detachably connected. In this way, when the aisle 5 needs to be opened, the two shielding rods are first separated, and then the two shielding rods are respectively driven to rotate around the rotating ends to open the aisle 5 and facilitate people to go up and down. When the aisle 5 needs to be closed, the two shielding rods are respectively driven to rotate around the rotating ends so that the opposite ends of the two shielding rods are close to each other and connected to close the aisle 5 to prevent people from falling from the aisle 5.

[0129] In one embodiment of the present invention, the frame 1 includes a first bracket 14 and a second bracket 15, and the second bracket 15 is rotatably mounted on the first bracket 14 around an axis extending in a first horizontal direction. Within its movable range, the second bracket 15 has the function of rotating to a storage position close to the first bracket 14, and rotating to a load-bearing position for carrying a seat assembly, wherein the two seat assemblies are respectively arranged on the first bracket 14 and the second bracket 15. When the frame 1 is in the load-bearing position, the first bracket 14 is flush with the second bracket 15, so that the frame 1 is in a horizontal state to support the two seat assemblies, so that the two seat assemblies 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 are close to each other, so that the frame 1 is in a folded state for storage or transportation. In this way, through the rotation of the second bracket 15, the frame 1 can support the two seat assemblies so that the seat assemblies can be used to carry people or goods, and the frame 1 can be folded for convenient storage or transportation.

[0130] In order to enable the first bracket 14 and the second bracket 15 to rotate relative to each other, please refer to Figures 11 to 14The frame 1 has two first side edges 111 located in the first direction, and the carrier 100 also includes two first mounting arms 62, two second mounting arms 63, and a rotating shaft. The two first mounting arms 62 and the two second mounting arms 63 are respectively installed on the two first side edges 111, and 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 rotating shaft are respectively passed through the two first mounting holes and the two second mounting holes. In this way, by providing the two first mounting arms 62 and the two second mounting arms 63, so as to provide the two first mounting holes and the two second mounting holes, at the same time, through the rotating shaft and the two first mounting holes and the two second mounting holes, the second bracket 15 can be rotated relative to the first bracket 14 around the axis extending in the first horizontal direction, so that the second bracket 15 can be rotated to be flush with the first bracket 14, so that the frame 1 is in a horizontal state, and can also be rotated 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.

[0131] Furthermore, there are various locations for the two first mounting arms 62 and the two second mounting arms 63. The two first mounting arms 62 and the two second mounting arms 63 can be set above the frame 1 or below the frame 1. The present invention is not limited to this. However, since an aisle 5 is formed above the frame 1, if the two first mounting arms 62 and the two second mounting arms 63 are set above the frame 1, it will affect the passengers getting on and off the frame 1. For this reason, in this embodiment, the two first mounting arms 62 and the two second mounting arms 63 are extended downward so that the two first mounting arms 62 and the two second mounting arms 63 can avoid the aisle 5 to avoid affecting the passengers getting on and off the frame 1.

[0132] It is understandable that the two first mounting arms 62 and the two second mounting arms 63 need to be provided correspondingly, that is, the two first mounting arms 62 and the two second mounting arms 63 need to be provided below the vehicle frame 1 at the same time.

[0133] In order to lock the first bracket 14 and the second bracket 15, in one embodiment, refer to Figures 11 to 14, the second bracket 15 is provided with a locking hole, and the frame 1 further includes a locking pin 61 movably mounted on the first bracket 14 along the first horizontal direction. Within its movable stroke, the locking pin 61 has a locking position penetrated through the locking hole and an unlocking position separated from the locking hole, wherein, when the locking pin 61 is in the locked position, the frame 1 is in the load-bearing position, and when the locking pin 61 is in the unlocked position, the frame 1 can be rotated to the storage position. When the first bracket 14 and the second bracket 15 need to be flush, the locking pin 61 moves along the first horizontal direction to the locking position, and the pin shaft is penetrated in the locking hole to limit the rotation of the second bracket 15, so that the first bracket 14 can be aligned with the second bracket 15. The two brackets 15 remain 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 unlocking position, and the pin shaft is outside the locking hole, so as to release the rotation restriction of the second bracket 15, so that the second bracket 15 can be rotated to the storage position to put the frame 1 in a folded state. In this way, by providing the locking pin 61 and the locking hole to lock or unlock the relative rotation of the first bracket 14 and the second bracket 15, the frame 1 can be kept in a horizontal state to support the seat assembly, and the frame 1 can be folded into the storage state for easy storage or transportation.

[0134] In another embodiment, see Figure 35 The first bracket 14 and the second bracket 15 are rotatably connected through a rotating positioning structure 16. The rotating positioning structure 16 includes two positioning seats that are relatively and rotatably arranged in a first direction, and a positioning member arranged 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 along the first horizontal direction. Within its movable range, it has a positioning position and an avoidance position. When in the positioning position, the positioning member cooperates with the two positioning seats to limit the rotation of the two positioning seats. When in the avoidance position, the positioning member is released from cooperation with at least one of the positioning seats so that the two positioning seats can rotate relative to each other.

[0135] In one embodiment of the present invention, the vehicle 100 further includes two first wheels 71 spaced apart on the frame 1 along a first horizontal direction, and two second wheels 72 spaced apart on the frame 1 along the first horizontal direction. The first wheels 71 and the second wheels 72 are spaced apart along the 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. In this way, by providing the two first wheels 71 and the 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 located 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 is borrowed so that the two first wheels 71 can be hidden in the two second wheels 72, which 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.

[0136] Furthermore, there are various ways to connect the first wheel 71 to the frame 1. The first wheel 71 can be fixedly mounted on the frame 1 or detachably mounted on the frame 1, etc., and the present invention is not limited to this. Similarly, there are various ways to connect the second wheel 72 to the frame 1. The second wheel 72 can be fixedly mounted on the frame 1 or detachably mounted on the frame 1, etc., and the present invention is not limited to this. Specifically, in this embodiment, the first wheel 71 and / or the second wheel 72 are detachably mounted on the frame 1. In this way, the detachable structure facilitates loading and unloading, so that wheels of different specifications can be replaced as needed.

[0137] In one embodiment of the present invention, there are multiple types of vehicles 100. In this embodiment, the vehicle 100 includes a child trailer or a child stroller. It can be understood that the child trailer or child stroller can be a stroller or trailer that can be driven by a child, or a stroller or trailer that can be provided for a child to ride in, etc. The present invention does not limit this.
