[0030] In the present application, the first rotating direction orientation or positional relationship is based on the direction of the arrow in the figure. Figure 1The orientation or positional relationship shown. It needs to be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0031] An embodiment of the present application provides a trolley, please refer to Figures 1-7 , the trolley includes a frame body 10 and at least one table board assembly 20.

[0032] At least one side of the frame body 10 is provided with the table board assembly 20, and the table board assembly 20 has a rotating end rotatably connected with the frame body 10. The table board assembly 20 has an initial state with a first included angle with the outer side wall of the frame body 10, and a use state with a second included angle with the outer side wall of the frame body 10. The table board assembly 20 can rotate relative to the frame body 10 around the rotating end to switch between the initial state and the use state.

[0033] Specifically, the trolley refers to a vehicle used for carrying objects by human power, and its use range is not limited. For example, the trolley is used for outdoor camping. For the convenience of description, the present application takes the trolley as an example for describing the outdoor camping trolley.

[0034] The frame body 10 is the main structure of the trolley, which is usually made of metal or plastic material, used for carrying and supporting other components.

[0035] The table board assembly 20 refers to the component on the trolley which is usually used for placing articles or as a work surface.

[0036] The number of table boards included in the table board assembly 20 is not limited. For example, the table board assembly 20 includes one table board. For another example, the table board assembly 20 includes two table boards.

[0037] The rotating end refers to the part of the table board assembly 20 rotatably connected with the frame body 10, and the table board assembly 20 rotates relative to the frame body 10 through the rotating end.

[0038] The initial state of the table board assembly 20 refers to the state of the table board assembly 20 when it is not unfolded, at which time the included angle between the table board assembly 20 and the outer side wall of the frame body 10 is small.

[0039] The use state of the table board assembly 20 refers to the state of the table board assembly 20 when it is unfolded to provide a multifunctional work and dining platform for the trolley, at which time the included angle between the table board assembly 20 and the outer side wall of the frame body 10 is large.

[0040] The first included angle refers to an angle between the table board assembly 20 and the outer side wall of the frame body 10 when the table board assembly 20 is in the initial state. For example, the first included angle is 0°, and the table board assembly 20 and the outer side wall of the frame body 10 to which the table board assembly 20 is rotationally connected are parallel.

[0041] It can be understood that the table board assembly 20 and the outer side wall of the frame body 10 can also form an included angle when the table board assembly 20 is in the initial state, and the first included angle is smaller and close to 0°. For example, the first included angle is in the range of 0°-5°. The table board assembly 20 can be inclined to the outside of the frame body 10 relative to the side wall of the frame body 10, or can be inclined to the inside of the frame body 10 relative to the side wall of the frame body 10.

[0042] The second included angle refers to an angle between the table board assembly 20 and the outer side wall of the frame body 10 when the table board assembly 20 is in the use state. For example, the second included angle is 90°, and the table board assembly 20 and the outer side wall of the frame body 10 to which the table board assembly 20 is rotationally connected are perpendicular.

[0043] It can be understood that the table board assembly 20 and the outer side wall of the frame body 10 can also form an included angle when the table board assembly 20 is in the use state, and the second included angle is larger and close to 90°. For example, the second included angle is in the range of 85°-95°.

[0044] It can be understood that the second included angle is larger than the first included angle.

[0045] The number of the table board assemblies 20 can be one or more.

[0046] At least one side of the frame body 10 is provided with the table board assembly 20 means that only one side of the frame body 10 can be provided with the table board assembly 20, or multiple sides of the frame body 10 can be respectively provided with the table board assembly 20.

[0047] For example, the table board assembly 20 is one, and is arranged on one side of the frame body 10. For example, the table board assembly 20 is two, and is arranged on two sides of the frame body 10. For example, the table board assembly 20 is three, and is arranged on three sides of the frame body 10. For example, the table board assembly 20 is four, and is arranged around the frame body 10.

[0048] The table board assembly 20 is rotationally connected with the frame body 10, and the specific connection manner is not limited as long as the table board assembly 20 can rotate relative to the frame body 10, and can support the table board assembly 20 in the use state.

[0049] For example, the trolley comprises a rotating support 30 connected with the frame body 10 and the rotating end respectively, so that the frame body 10 can rotate relative to the frame body 10; when the table board assembly 20 is in the use state, the rotating support 30 supports the table board assembly 20 and limits the rotation of the table board assembly 20. In this way, on the one hand, the rotating support 30 can provide support for the table board assembly 20 when the table board assembly 20 is converted from the initial state to the use state, maintain the stability of the table board assembly 20, and prevent the table board assembly 20 from accidentally rotating or collapsing. On the other hand, the user can adjust the angle of the table board assembly 20 through the rotating support 30 as needed to adapt to different use scenarios.

[0050] Specifically, the rotating support 30 refers to a mechanical component connecting the table board assembly 20 and the frame body 10, which allows the table board to rotate within a certain range and provides necessary support and stability for the table board assembly 20 when the table board assembly 20 is in the use state.

[0051] The structure type of the rotating support 30 is not limited. For example, the rotating support 30 is a hinge.

[0052] For another example, the rotating support comprises two hinges, which are arranged along the axial direction of the rotating end, thereby improving the rotation stability of the table board assembly 20.

[0053] An embodiment of the present application provides a trolley, which comprises a frame body 10 and at least one table board assembly 20. At least one side of the frame body 10 is provided with the table board assembly 20, the table board assembly 20 has a rotating end rotationally connected with the frame body 10, the table board assembly 20 has an initial state with a first included angle with the outer side wall of the frame body 10 and a use state with a second included angle with the outer side wall of the frame body 10, and the table board assembly 20 can rotate relative to the frame body 10 around the rotating end to switch between the initial state and the use state. By rotating the table board assembly 20 to adjust the angle between the table board assembly 20 and the frame body 10, the rapid switching between the initial state and the use state is realized, thereby improving the assembly portability of the trolley.

[0054] In an embodiment, please refer to Figure 1 , Figure 2 and Figure 3 When the table board assembly is in the initial state, the table board assembly 20 extends along the vertical direction; when the table board assembly 20 is in the use state, the table board assembly 20 extends along the horizontal direction. On the one hand, in the initial state, the table board assembly 20 extends along the vertical direction, which can reduce the size of the trolley and reduce the space occupied by the trolley. In the use state, the table board assembly 20 extends along the horizontal direction, providing a stable work platform and increasing the practicability of the trolley.

[0055] In an embodiment, please refer to Figure 1、 Figure 2 and Figure 3 The table board assembly 20 comprises a first table board 21 and a second table board 22, the first table board 21 has a rotating end, one end of the second table board 22 is rotatably connected with the rotating end, the table board assembly 20 has an open state in which the first table board 21 and the second table board 22 form a third angle, and a folding state in which the first table board 21 and the second table board 22 form a fourth angle. Thus, by setting the first table board 21 and the second table board 22, the table board assembly 20 provides a larger working platform in the open state, further increasing the practicability of the trolley.

[0056] Specifically, the first table board 21 has a rotating end, allowing the entire table board assembly 20 to rotate relative to the trolley frame body 10.

[0057] One end of the second table board 22 is rotatably connected with the rotating end of the first table board 21, for expanding or folding the table board.

[0058] The open state of the table board assembly 20 refers to the state in which the first table board 21 and the second table board 22 are separated, and the extension directions of the first table board 21 and the second table board 22 are opposite.

[0059] The folding state of the table board assembly 20 refers to the state in which the first table board 21 and the second table board 22 are attached, and the extension directions of the first table board 21 and the second table board 22 are the same.

[0060] The third angle refers to the angle between the first table board 21 and the second table board 22 when the table board assembly 20 is in the open state. For example, the angle of the third angle is 180°, at this time the first table board 21 and the second table board 22 are completely unfolded, forming parallel planes, and the extension directions of the first table board 21 and the second table board 22 are opposite.

[0061] It can be understood that the third angle of the table board assembly 20 in the open state can also be an angle close to 180°, for example, the angle of the third angle is in the range of 175°-185°.

[0062] The fourth angle refers to the angle between the first table board 21 and the second table board 22 when the table board assembly 20 is in the folding state. For example, the angle of the fourth angle is 0°, at this time the first table board 21 and the second table board 22 are attached, and the extension directions of the first table board 21 and the second table board 22 are the same.

[0063] It can be understood that the fourth angle of the table board assembly 20 in the folding state can also be an angle close to 0°, for example, the angle of the fourth angle is in the range of 0°-5°.

[0064] It can be understood that the angle of the third angle is greater than the angle of the fourth angle.

[0065] The specific connection mode of the first table board 21 and the second table board 22 is not limited, as long as the second table board 22 and the first table board 21 can rotate relative to each other, and the second table board 22 and the first table board 21 maintain a fixed angle when the table board assembly 20 is in an open state.

[0066] In an embodiment, referring to Figure 1 and Figure 2 , the use states include a first use state and a second use state; when the table board assembly 20 is in the first use state, the first table board 21 and the second table board 22 are in a folded state; and when the table board assembly 20 is in the second use state, the first table board 21 and the second table board 22 are in an open state. Thus, the user can select different use states of the table board according to needs to adapt to different spaces and use requirements.

[0067] Specifically, the table board assembly 20 has two use states, and the first use state is one of the use states of the table board assembly 20.

[0068] Exemplarily, referring to Figure 1 , when the table board assembly is in the first use state, at least part of the projection of the first table board 21 and at least part of the projection of the second table board 22 are located outside the projection range of the frame body 10 in the horizontal projection plane, and both extend away from the projection of the frame body 10. Thus, additional use space is provided without increasing the size of the frame body 10.

[0069] Specifically, the horizontal projection plane refers to a projection plane parallel to the horizontal plane.

[0070] The projection range refers to the area occupied by the projection of the object on the horizontal projection plane.

[0071] The horizontal projection of the first table board 21 can be located outside the projection range of the frame body 10, or part of it can be located outside the projection range of the frame body 10.

[0072] The horizontal projection of the second table board 22 can be located outside the projection range of the frame body 10, or part of it can be located outside the projection range of the frame body 10.

[0073] That is, in the first use state, the first table board 21 and the second table board 22 are attached and extend outward from the frame body 10.

[0074] The second use state is one of the use states of the table board assembly 20.

[0075] Exemplarily, referring to Figure 2When the table board assembly 20 is in the second use state, in the horizontal projection plane, at least part of the projection of the first table board 21 is located outside the projection range of the frame body 10 and extends in a direction away from the projection of the frame body 10; at least part of the projection of the second table board 22 is located within the projection range of the frame body 10 and extends in a direction away from the projection of the first table board 21. Thus, in the second use state, the table board assembly 20 provides a larger working platform for the frame body 10, further increasing the practicability of the trolley.

[0076] Specifically, the horizontal projection of the first table board 21 can be located outside the projection range of the frame body 10, or a part of the horizontal projection of the first table board 21 can be located outside the projection range of the frame body 10.

[0077] The horizontal projection of the second table board 22 can be located within the projection range of the frame body 10, or a part of the horizontal projection of the second table board 22 can be located within the projection range of the frame body 10.

[0078] The first table board 21 extends to a side away from the frame body 10, and the second table board 22 extends to a side close to the frame body 10, and the extending directions of the first table board 21 and the second table board 22 are opposite.

[0079] In an embodiment, referring to Figure 2 The frame body 10 has a receiving cavity, and the top of the receiving cavity is open to form a storage opening; when the table board assembly 20 is in the second use state, in the horizontal projection plane, at least part of the projection of the storage opening is located outside the projection range of the second table board 22. Thus, in the use state of the table board assembly 20, the user can still conveniently access the articles in the receiving cavity.

[0080] Specifically, the receiving cavity refers to the internal space of the frame body 10 for storing articles.

[0081] The storage opening is an opening at the top of the receiving cavity, so that the receiving cavity is in communication with the outside, allowing articles to enter or be taken out of the receiving cavity.

[0082] In the second use state, at least part of the projection of the storage opening is located outside the projection range of the second table board 22, that is, in the second use state of the table board assembly 20, the second table board 22 does not completely cover the storage opening of the receiving cavity, thereby maintaining the convenience of accessing articles.

[0083] At least part of the projection of the storage opening being located outside the projection range of the second table board 22 means that the projection of the storage opening can be entirely located outside the projection range of the second table board 22, or a part of the projection of the storage opening can be located outside the projection range of the second table board 22.

[0084] In an embodiment, referring to Figure 2 The table board assembly includes a rotating shaft 23, and the rotating shaft 23 is connected to the rotating end and the second table board 22, respectively.

[0085] In the process that the table board assembly 20 switches from the folded state to the open state, the second table board 22 rotates relative to the rotating end along the first rotating direction around the rotating shaft 23; when the table board assembly 20 is in the open state, the rotating shaft 23 limits the rotation of the second table board 22 along the first rotating direction. In this way, on the one hand, the table board assembly 20 can be switched between the folded state and the open state through the rotating shaft 23, which is convenient to operate. On the other hand, the rotating shaft 23 can limit the rotation of the second table board 22 along the first rotating direction in the open state, which provides stability for the table board assembly 20.

[0086] Specifically, the rotating shaft 23 refers to a mechanical component in the table board assembly 20, which is the center point of the rotation of the table board assembly 20 and allows the second table board 22 to rotate around it.

[0087] The first rotating direction refers to the rotating direction of the second table board 22 when the table board assembly 20 switches from the folded state to the open state.

[0088] When the table board assembly 20 is in the open state, the rotating shaft 23 can limit the rotation of the second table board 22 to keep the table board assembly 20 stable.

[0089] It should be noted that when the table board assembly 20 is in the open state, the rotating shaft 23 can only limit the rotation of the second table board 22 along the first rotating direction, without limiting the rotation of the second table board 22 along the second rotating direction opposite to the first rotating direction. Of course, in other embodiments, the rotating shaft 23 can also limit the rotation of the second table board 22 along the second rotating direction.

[0090] The structure of the rotating shaft 23 is not limited. For example, the rotating shaft 23 adopts a bearing design to ensure the smoothness and reduce the friction when the second table board 22 rotates.

[0091] For another example, the rotating shaft 23 includes a locking structure, which fixes the position of the second table board 22 in the open state to prevent accidental rotation.
