[0029] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the described embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application. It can be understood that, without conflict, some technical means described in the various embodiments herein may be replaced or combined with each other.
[0030] In the description of the specification and claims of this application, if there are terms such as "first", "second", etc., they are only used to distinguish the described objects and do not have any sequential or technical meanings. Thus, the objects defined with "first", "second", etc. may explicitly or implicitly include one or more of such objects. Also, words such as "a" or "one" do not indicate a quantity limitation but rather indicate the existence of at least one, and "multiple" means not less than two.
[0031] In the description of the specification and claims of this application, if there are terms such as "connect", "install", "fix", "accommodate", etc., without special instructions, they should all be understood in a broad sense. For example, "connect" can be a split connection or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a non-detachable connection or a detachable connection. Another example is that "accommodate" does not necessarily mean complete accommodation as a whole, and this concept also includes a situation where a part protrudes outside and is partially accommodated. For those skilled in the art, the specific meanings of the foregoing terms in this application can be understood according to specific circumstances.
[0032] In the description of the specification and claims of this application, if there are terms such as "upper", "lower", "horizontal", etc. indicating an orientation or positional relationship, it is based on the orientation or positional relationship shown in the drawings. This is only for the purpose of clearly and simply describing this application, rather than indicating or implying that the referred element must have a specific direction, be constructed and operated in a specific orientation. These directional terms are relative concepts used for relative description and clarification, and can change accordingly with the change of the orientation in which the components are placed in the drawings. For example, if the device in the figure is flipped, the element described as "below" other elements will be positioned "above" other elements.
[0033] In the description of the specification and claims of this application, if there is the term "if", depending on the context, it can usually be interchanged with "when", "at the time of", "in response to a determination", or "in response to detecting".
[0034] In the description of the specification and claims of this application, if there is "in the direction of" regarding motion, including motion with a directional component, it is not necessarily to understand the term "in the direction of" as only motion in that one direction. For those skilled in the art, the specific meanings of the foregoing terms in this application can be understood according to specific circumstances.
[0035] Such as Figures 1 to 6As shown in the figure, a portable folding camping cart includes a cart frame with a deployed state and a folded state, a wheel assembly provided at the bottom of the cart frame, and a locking mechanism for locking the cart frame in the deployed state. The cart frame includes a front bracket 1, a rear bracket 2, and a push rod bracket 3 that are rotatably connected. A storage basket 4 that can be folded and retracted back and forth is rotatably provided between the front bracket 1 and the rear bracket 2. A linkage 5 is rotatably connected between the folding and retracting point of the storage basket 4 and the push rod bracket 3.
[0036] In this embodiment, the storage basket 4 includes an upper surrounding frame 410 formed by rotatably connecting an upper front frame 411 and an upper rear frame 412, a lower surrounding frame 420 formed by rotatably connecting a lower front frame 421 and a lower rear frame 422, and a cloth cover provided on the upper surrounding frame 410 and the lower surrounding frame 420. The upper front frame 411 and the lower front frame 421 are respectively rotatably connected to the upper and lower parts of the front bracket 1, and the upper rear frame 412 and the lower rear frame 422 are respectively rotatably connected to the upper and lower parts of the rear bracket 2. The above storage basket 4 is only a specific basket structure that can be folded and retracted back and forth, but is not limited thereto. It can also be other basket structures that can be folded and retracted back and forth, and will not be specifically described and limited here.
[0037] In this embodiment, the upper end of the linkage 5 is rotatably connected to the lower part of the push rod bracket 3, and the lower end of the linkage 5 is rotatably connected to the rotation point between the upper front frame 411 and the upper rear frame 412.
[0038] When the cart frame is in the deployed state, the storage basket 4 is deployed and placed flat between the front bracket 1 and the rear bracket 2. When the cart frame is folded, the push rod bracket 3 is retracted towards the rear bracket 2. Driven by the push rod bracket 33, the linkage 5 drives the rotation point between the upper front frame 411 and the upper rear frame 412 to move upward, thereby causing the middle part of the storage basket 4 to fold and retract upward and backward and downward, and causing the front bracket 1 to retract relative to the rear bracket 2, thus completing the folding of the whole vehicle.
[0039] In this embodiment, the lower part of the front bracket 1 has a front cross bar 101, the lower part of the rear bracket 2 has a rear cross bar 201, and the lower parts of the lower front frame 421 and the lower rear frame 422 are respectively sleeved on the front cross bar 101 and the rear cross bar 201 through sleeves. When the cart frame is in the deployed state, the deployed lower surrounding frame 420 is placed flat above the front cross bar 101 and the rear cross bar 201. This design improves the load-bearing stability of the storage basket 4.
[0040] In this embodiment, the upper end of the front bracket 1, the upper end of the rear bracket 2, and the lower end of the push rod bracket 3 are preferably rotatably connected coaxially. When the cart frame is in the unfolded state, the front bracket 1, the rear bracket 2, and the push rod bracket 3 are unfolded in a V shape. The rotation connection point between the linkage 5 and the push rod bracket 3 is located below the rotation connection points among the front bracket 1, the rear bracket 2, and the push rod bracket 3. After the cart frame is folded, the rotation connection point between the linkage 5 and the push rod bracket 3 is located in front of and above the rotation connection points among the front bracket 1, the rear bracket 2, and the push rod bracket 3.
[0041] In this embodiment, the locking mechanism is disposed between the push rod bracket 3 and the front bracket 1 or between the push rod bracket 3 and the rear bracket 2. Since the locking mechanism for locking the unfolding of the cart is a conventional technique in this technical field and there are various structural types, no specific description or limitation is given here.
[0042] In this embodiment, the wheel assembly includes a front wheel assembly 6 installed below the front bracket 1 and a rear wheel assembly 7 disposed below the rear bracket 2. Among them, the front wheel assembly 6 and the rear wheel assembly 7 are preferably wheels with shock absorption functions. Since the setting of such wheel assemblies is a conventional technique in this technical field, no specific description or limitation is given here.
[0043] The present utility model adopts a traditional cart structure as the main frame structure and is configured with a storage basket 4 that can be folded and retracted forward and backward. When the cart frame is folded, the push rod bracket 3 is retracted to the rear side of the rear bracket 2. The storage basket 4 is folded and retracted forward and backward under the drive of the linkage 5, and the front bracket 1 is retracted to the front side of the rear bracket 2, thereby completing the folding of the whole vehicle. The overall structure is novel and simple, and the whole vehicle can be quickly folded.
