Description

Technical Field

[0001] The invention relates to an outdoor cart, in particular to a simple folding and reinforcing structure of an outdoor cart. Background Art

[0002] With the development of society, young people nowadays like outdoor camping. Camping requires a lot of supplies to be carried, so camping cars have appeared to transport supplies.

[0003] In order not to take up space, camping cars are generally foldable. For example, a product previously applied by our company (patent number: 202320102881.2) is provided with a reinforcing rod at the bottom of the frame to ensure the overall strength of the camping car. However, the previous product has two groups of reinforcing rods, each with two rods, and the reinforcing rods are connected together by hinges with connecting joints. The above method not only has many parts and a complex structure, but also the structural strength at the hinge point is not high, resulting in insufficient strength of the bottom of the frame.

[0029] As those skilled in the art can fully understand, the features of the different embodiments of the present disclosure can be coupled or combined with each other in part or in whole, and can cooperate with each other in various ways and be driven technically. The embodiments of the present disclosure can be performed independently of each other, or can be performed together in a mutually dependent relationship.

[0030] Reference Figure 1 The present invention discloses a simple folding and reinforcing structure of an outdoor cart, comprising a stand 1 and a stand 2, a bottom frame 3 hinged to the stand 1 and a bottom frame 4 hinged to the stand 2, the stand 1, the stand 2, the bottom frame 3 and the bottom frame 4 are all welded from round tubes, the stand 1, the stand 2, the bottom frame 3 and the bottom frame 4 constitute a square frame of the cart, and when folded, the bottom frame 3 and the bottom frame 4 can each be turned over 90 degrees to be parallel and overlapped with the stand 1 and the stand 2, thereby saving space. The above structure is a prior art and is not described in detail.

[0031] As shown in the figure, the bottom frame 1 3 and the bottom frame 2 4 are hinged to each other, and a reinforcing rod assembly is provided below the bottom frame 1 3 and the bottom frame 2 4, and the reinforcing rod assembly includes a rod 1 5 and a rod 2 6, the rod 1 5 is rotatably connected to the stand 1, and the rod 2 6 is rotatably connected to the stand 2 2, and a slide groove or a slide hole 7 is provided on the rod 1 5, and the rod 2 6 is slidably matched with the slide groove or the slide hole 7, so that when the bottom frame 1 3 and the bottom frame 2 4 are relatively rotated and folded, the rod 1 5 and the rod 2 6 can also cooperate with the bottom frame 1 3 and the bottom frame 2 4 to make corresponding rotations, and at the same time, the rod 2 6 can move along the slide groove or the slide hole 7 and be side by side and roughly aligned with the rod 1 5, and be parallel and tightly attached to the stand 1 and the stand 2 2 to achieve the final folding.

[0032] As shown in the figure, the sliding hole 7 in the present application is the inner hole of the rod 1 5. When unfolded, the end of the rod 2 6 is located in the inner hole, and when folded, the rod 2 6 is completely retracted into the inner hole. As a preferred structure, the rod 1 5 and the rod 2 6 are both square tubes, and the inner hole is a square hole, so that the rod 2 6 is prevented from rotating relative to the inner hole, thereby improving the overall stability.

[0033] As shown in the figure, sleeves 8 are provided at the ends of the rod 1 5 and the rod 2 6, and the stand 1 and the stand 2 both include vehicle stand tubes. The sleeve 8 is rotatably matched with the corresponding vehicle stand tube, and the upper end of the sleeve 8 is restricted by the bottom frame 1 3 or the bottom frame 2 4 and cannot be dislodged, while the lower end of the sleeve 8 is restricted by the wheel frame and cannot be dislodged.

[0034] like Figures 2 to 4 As shown, a folding locking mechanism is provided between the bottom frame body 1 3 and the bottom frame body 2 4, and the folding locking mechanism includes a folding locking piece 1 9 provided on the bottom frame body 1 3, a folding locking piece 2 10 provided on the bottom frame body 2 4, and a locking rod 11, the folding locking piece 1 9 is hinged with the folding locking piece 2 10, a card slot 12 is provided on the folding locking piece 1 9, a guide hole 13 is provided on the folding locking piece 2 10, an end of the locking rod 11 is located in the guide hole 13, and can be inserted into the card slot 12 by rotating the folding locking piece 2 10, wherein the guide hole 13 is a long hole, and the card slot 12 and the guide hole 13 are inclinedly arranged, so that when folding, the locking rod 11 can squeeze the card slot 12 and the guide hole 13 to drive the folding locking piece 1 9 and the folding locking piece 2 10 to rotate relative to each other, and an elastic piece 14 is provided between the locking rod 11 and the folding locking piece 9 to enable the locking rod 11 to be located in the card slot 12. In order to stably lock the bottom frame 1 3 and the bottom frame 2 4, a limiting groove 15 is provided on the folding locking member 9, and a limiting rod 16 that can be inserted into the limiting groove 15 is provided on the folding locking member 9, so that after unfolding, the limiting groove 15 cooperates with the limiting rod 16 to keep the folding locking member 1 9 and the folding locking member 2 10 in a horizontal state and will not continue to rotate.

[0035] The principle of the above structure is that the locking rod 11 is fixed to the drawstring 21, and the drawstring 21 is connected to the cloth bag laid in the frame. When it needs to be folded, the user lifts the bottom surface of the cloth bag and the drawstring 21 drives the locking rod 11 to move along the guide hole 13, so that the locking rod 11 escapes from the slot 12 and abuts against the hole wall of the guide hole 13, while driving the folding locking member 2 10 and the folding locking member 1 9 to move upward. While the folding locking member 2 10 and the folding locking member 1 9 move upward, they will rotate relative to each other, thereby realizing the relative closing and folding of the bottom frame 1 3 and the bottom frame 2 4.

[0036] As shown in the figure, the specific structure of the hinge is that it also includes a hinge rod 17, a support plate 18 is relatively provided on the folding locking member 9, a receiving groove 19 is provided on the folding locking member 10, the support plate 18 is located in the receiving groove 19, a hinge hole 1 is provided on the support plate 18, and a hinge hole 2 is provided on the groove wall of the receiving groove 19. The end of the hinge rod 17 is located in the corresponding hinge hole 1 and hinge hole 2. Of course, the hinge rod can adopt a screw rod, one end of which is restricted by a nut and the other end is restricted by an end cap and cannot fall out of the hinge hole.

[0037] The elastic member 14 is a tension spring, one end of which is connected to the locking rod 11 , and the other end of which is connected to the hinge rod 17 . The tension spring can keep the locking rod 11 in the slot 12 .

[0038] The clamping slot 12 is disposed on the support plate 18 , and the guide hole 13 is disposed on the groove wall of the receiving groove 19 . The above structure is convenient for processing and assembly.

[0039] The folding locking member 1 9 and the folding locking member 2 10 are both provided with connecting grooves 20, and the bottom frame 1 3 and the bottom frame 2 4 are locked with the corresponding connecting grooves 20. During installation, they are positioned by the connecting grooves 20, and then the folding locking member 1 9 and the folding locking member 2 10 are fixed to the bottom frame 1 3 and the bottom frame 2 4 respectively by screws.

[0040] The above is a detailed introduction to a simple folding and reinforcing structure of an outdoor cart provided by an embodiment of the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
