The foldable storage basket provided in this embodiment is set at the rear 61 of the electric vehicle 6. The electric vehicle 6 can be used as a golf cart, sightseeing vehicle, shared electric vehicle, passenger electric vehicle, etc.

[0048] The foldable storage basket includes a fixing frame 3, a basket body 1, and an opening and closing device 2; the fixing frame 3 is installed at the rear 61 of the electric vehicle 6; the basket body 1 is rotatably connected to the fixing frame 3 and is folded onto or unfolded relative to the fixing frame 3 via the opening and closing device 2; the unfolded basket body 1 and the fixing frame 3 form a frame structure with an open top (e.g., Figure 1 The frame structure is used for storage, and the basket 1 is folded and stored in the fixing frame 3 (e.g., Figure 12 It is easy to store and saves space.

[0049] A rotation limiting device 4 is provided between the fixing frame 3 and the basket 1. The rotation limiting device 4 includes a slow-descent device 41, which is a pneumatic or hydraulic rod. The slow-descent device 41 is connected to the bottom plate 11 of the basket 1. The slow-descent device 41 is provided on at least one side of the bottom plate 11 of the basket 1. When the basket 1 is unfolded, the bottom plate 11 of the basket 1 flips downward, and the slow-descent device 41 slows down the downward speed of the bottom plate 11 of the basket 1.

[0050] The rotation limiting device 4 also includes a pull rope 42, one end of which is fixed to the fixing frame 3 and the other end is fixed to the bottom plate 11 of the basket body 1; the pull rope 42 is provided on at least one side of the bottom plate 11 of the basket body 1; after the basket body 1 is unfolded, the fixing frame 3, the bottom plate 11 of the basket body 1 and the pull rope 42 form a triangular structure, which makes the unfolded storage basket structure more stable. The pull rope 42 can be made of materials such as plastic, fiber, and metal.

[0051] In this embodiment, as Figure 2 A slow-descent device 41 is provided on one side of the bottom plate 11 of the basket 1, and a pull rope 42 is provided on the other side. The slow-descent device 41 can prevent the bottom plate 11 of the basket 1 from falling down instantly. When the opening and closing device 2 releases the lock between the basket 1 and the fixing frame 3, the bottom plate 11 of the basket 1 is slowly lowered under the action of the slow-descent device 41. The pull rope 42 is gradually pulled open until the pull rope 42 is straightened and forms a triangular structure with the fixing frame 3 and the bottom plate 11 of the basket 1. When folding is required, external force is applied to squeeze the slow-descent device 41 and the bottom plate 11 of the basket 1 is folded into the fixing frame 3.

[0052] like Figure 3 The basket 1 has the following specific structure: it includes a fence 12 rotatably connected to a base plate 11, and two guardrails 13 rotatably connected to both sides of the fence 12. The fence 12 is positioned opposite to the fixing frame 3. When folded, the two guardrails 13 rotatably fold onto the fence 12, the fence 12 rotatably folds onto the base plate 11, and the base plate 11 rotatably folds onto the fixing frame 3. When unfolded, the guardrails 13 are rotated and unfolded relative to the fence 12, and the end of the guardrail 13 away from the fence 12 is detachably connected to the fixing frame 3. The unfolded state of the guardrails 13 relative to the fence 12 is as follows: Figure 4 It should be noted that the rotary connection mentioned in this article can be achieved through a rotating shaft or a direct hinge. This rotary connection is existing technology and will not be described in detail here.

[0053] like Figure 4-10The opening and closing device 2 includes a pin 21, a rotating component 22, a connecting rod 24 connecting the pin 21 and the rotating component 22, and a slot 23 formed on the fixed frame 3. The fixed frame 3 includes a side plate 32, and the slot 23 is provided on the side plate 32. The bottom plate 11 of the basket body 1 has an opening 111 with rotation space in the middle, and the rotating component 22 is placed in the opening 111. The connecting rod 24 is placed in the bottom plate 11 of the basket body 1, and the pin 21 extends out from the side of the bottom plate 11 of the basket body 1. When the basket body 1 is folded, the opening 111 is provided on the outward side of the bottom plate 11 of the basket body 1. When the basket body 1 is folded on the fixed frame 3, rotating the rotating component 22 causes the pin 21 to be engaged with or disengaged from the slot 23. The slot 23 is a U-shaped slot with an opening 111 facing the pin 21; one end of the U-shaped slot is an arc-shaped structure 231 with the arc surface facing upward, which matches the movement trajectory of the pin 21 when engaging or disengaging from the slot 23.

[0054] The opening and closing device 2 operates as follows: when the basket 1 needs to be unfolded for use, the opening and closing device 2 releases the basket 1 relative to the fixing frame 3, such as... Figure 7 By rotating the rotating member 22 downwards, the rotating member 22 rotates outwards from the opening 111. The rotation of the rotating member 22 drives the pin 21 to rotate via the connecting rod 24, as shown below. Figure 6 The pin 21 moves outward from the slot 23 and disengages from the slot 23 along the arc structure 231. At this time, the basket 1 can flip downward relative to the fixed frame 3 and unfold to form a frame structure. When the basket 1 is folded against the fixed frame 3, as... Figure 10 By rotating the rotating member 22 upwards, the rotating member 22 is inserted into the opening 111. The rotation of the rotating member 22 drives the pin 21 to rotate via the connecting rod 24. Figure 9 The pin 21 moves toward the slot 23 and engages with the slot 23 along the arc structure 231, fixing the basket 1 to the fixing frame 3 to maintain the folded state.

[0055] like Figure 11 The guardrail 13 and the fixing frame 3 are detachably connected in such a way that the end of the guardrail 13 away from the fence 12 is provided with a connector 5 (such as...). Figure 3The fixing frame 3 is provided with a socket 31 corresponding to the position of the plug-in component 5; the plug-in component 5 includes a housing 51 and a pin 52, the housing 51 has an elastic element 53 inside; the pin 52 is inserted into the housing 51, and the rear end of the pin 52 is connected to the elastic element 53; the pin 52 can extend or retract from the housing 51 with the cooperation of the elastic element 53, and the pin 52 extends out of the housing 51 and plugs into the socket 31; the plug-in component 5 includes an unlocking element, which acts on the pin 52 to disengage it from the socket 31 to form a detachable connection. When the basket 1 is flipped downwards and stretched straight, the fence 12 rotates and unfolds relative to the bottom plate 11 of the basket 1 (e.g. Figure 4 After the guardrail 13 rotates and unfolds relative to the fence 12, the guardrail 13 is inserted into the socket 31 using the connector 5 (e.g., Figure 11 ), and fix the guardrail 13 to the fixing frame 3.

[0056] like Figure 11 The unlocking component includes a protrusion 521 on the pin 52 and a sliding groove on the housing 51. The protrusion 521 is placed in the sliding groove, and the pin 52 is confined within the housing 51. The sliding groove includes a first groove 511 and a second groove 512. The protrusion 521 can slide along the sliding groove and be placed in either the first groove 511 or the second groove 512. When the protrusion 521 is placed in the first groove 511, the elastic member 53 pops out the pin 52, and the pin 52 is inserted into the socket 31. The guardrail 13 is connected to the fixing frame 3. When the protrusion 521 is placed in the second groove 512, the pin 52 presses the elastic member 53 to retract into the housing 51, the pin 52 disengages from the socket 31, and the guardrail 13 separates from the fixing frame 3.

[0057] To improve the load-bearing capacity of the unfolded folding storage basket, a load-bearing structure is added between the connector 5 and the fixing frame 3 to provide support. The fixing frame 3 includes a side plate 32 with a protruding post 33, and a locking hole 513 on the housing 51. The guardrail 13 rotates and unfolds relative to the fence 12, and the locking hole 513 engages with the protruding post 33, forming a load-bearing structure together.

[0058] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
