[0040] Figure 6 This is a schematic diagram illustrating a foldable barbecue grill in a folded storage state according to an exemplary embodiment. Detailed Implementation

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0042] When storing portable barbecue grills in related technologies, they usually need to be disassembled into multiple independent parts. On the one hand, disassembly is required for both use and storage, which takes a long time. On the other hand, the independent parts are prone to being lost, and the loss of any part may render the barbecue grill unusable.

[0043] To address the problems existing in related technologies, this disclosure provides a foldable barbecue grill. The foldable barbecue grill includes two opposing first sidewalls, multiple second sidewalls, and a bottom wall. Both the second sidewalls and the bottom wall are rotatably connected to the first sidewalls. When the foldable barbecue grill is in its unfolded state, the first sidewalls, second sidewalls, and bottom wall are directly connected, forming a heat source housing cavity. When the foldable barbecue grill is in its retracted state, both the second sidewalls and the bottom wall are folded, and the second sidewalls are separated from the bottom wall. In this disclosure, when the barbecue grill is needed, the first sidewalls, second sidewalls, and bottom wall form a heat source housing cavity, ensuring the reliability of the heat source housing cavity. When the barbecue grill needs to be stored, only the second sidewalls and bottom wall need to be separated and folded; the first sidewalls, second sidewalls, and bottom wall remain as a single unit, requiring no disassembly and preventing loss.

[0044] According to exemplary embodiments of this disclosure, such as Figure 1 As shown, this embodiment of the present disclosure provides a foldable barbecue grill, which transforms its structure to switch between an unfolded state and a folded storage state, making it convenient for users to carry and barbecue when going out.

[0045] like Figure 1 As shown, the foldable barbecue grill includes two first sidewalls 10 disposed opposite to each other and a plurality of second sidewalls 20 disposed between the two first sidewalls 10.

[0046] In one example, see Figure 1 , Figure 3 and Figure 4 The diagram shows a foldable barbecue grill with two second sidewalls 20, namely two first sidewalls 10 and two second sidewalls 20 connected end to end, thereby enclosing a rectangular heat source accommodating cavity 40. The first sidewalls 10 and the second sidewalls 20 are used to block the heat source and prevent heat leakage.

[0047] In another example (not shown in the attached diagram), the foldable grill can be provided with two or more second sidewalls, with multiple second sidewalls along... Figure 1 As shown, the second sidewalls are arranged sequentially along the x-direction, forming a heat source cavity between any two adjacent second sidewalls. For example, multiple heat sources providing different temperatures can be placed in multiple heat source cavities, allowing for the simultaneous grilling of ingredients requiring different temperatures, or the grilling of the same ingredient at different stages above different heat source cavities, thus enhancing the grilling experience.

[0048] like Figure 1 , Figure 5 and Figure 6 As shown, the foldable barbecue grill also includes a bottom wall 30, which is disposed between the two first side walls 10. The bottom wall 30 forms the bottom surface of the heat source receiving groove to provide support for the heat source.

[0049] Among them, see Figures 2 to 5 The second sidewall 20 and the bottom wall 30 are both composed of at least two foldable panels. For example, the second sidewall 20 and the bottom wall 30 are both composed of two foldable panels. In some alternative embodiments, the second sidewall 20 and the bottom wall 30 may be composed of three, four or more panels, which will not be described in detail here.

[0050] See Figures 1 to 6 The two sides of the second sidewall 20 are rotatably connected to the first sidewall 10, and the two sides of the bottom wall 30 are rotatably connected to the two first sidewalls 10 respectively. Figures 1 to 6 It is understandable that by rotating the relative positions of the second sidewall 20 and the first sidewall 10, and rotating the relative positions of the bottom wall 30 and the first sidewall 10, and folding the second sidewall 20 and the bottom wall 30, the distance between the two first sidewalls 10 can be reduced. The folded second sidewall 20 and the bottom wall 30 are then stored between the two first sidewalls 10, thus switching the foldable barbecue grill to its foldable storage state (see...). Figure 6Correspondingly, when the second sidewall 20 and bottom wall 30 in the folded state are unfolded from the folded storage state, the second sidewall 20 and bottom wall 30 can be rotated in the opposite direction to increase the distance between the two first sidewalls 10. When the second sidewall 20 and bottom wall 30 are unfolded to the preset shape, the separated second sidewall 20 and bottom wall 30 can form a fit (direct connection), so that the first sidewall 10, the second sidewall 20 and the bottom wall 30 surround and define the heat source accommodating cavity 40.

[0051] In this embodiment, when the barbecue grill is needed, the first side wall, the second side wall, and the bottom wall enclose and define a heat source accommodating cavity. The first side wall, the second side wall, and the bottom wall are directly connected to ensure the reliability of the heat source accommodating cavity. When the barbecue grill needs to be stored, the second side wall and the bottom wall can be separated and folded. The first side wall, the second side wall, and the bottom wall remain as a whole and do not need to be disassembled, making them less likely to be lost.

[0052] In one exemplary embodiment, such as Figure 1 As shown, the foldable barbecue grill includes two opposing first side walls 10, multiple second side walls 20, and a bottom wall 30. The second side walls 20 and the bottom wall 30 are rotatably connected to the first side walls 10. When the foldable barbecue grill is in the unfolded state, the first side walls 10, the second side walls 20, and the bottom wall 30 are directly connected, and the first side walls 10, the second side walls 20, and the bottom wall 30 enclose and define a heat source accommodating cavity 40. When the foldable barbecue grill is in the stored state, the second side walls 20 and the bottom wall 30 are in the folded state, and the second side walls 20 and the bottom wall 30 are separated.

[0053] In this embodiment, as Figure 4 and Figure 5 As shown, the bottom wall 30 includes a first bottom plate 31 and a second bottom plate 32 that can be folded relative to each other. The first bottom plate 31 is rotatably connected to one of the two first side walls 10, and the second bottom plate 32 is rotatably connected to the other of the two first side walls 10. The first bottom plate 31 and the second bottom plate 32 are rotatably connected by a first preset pivot 33. The second side wall 20 includes a first side plate 21 and a second side plate 22 that can be folded relative to each other. The first side plate 21 is rotatably connected to one of the two first side walls 10, and the second side plate 22 is rotatably connected to the other of the two first side walls 10. The first side plate 21 and the second side plate 22 are rotatably connected by a second preset pivot 23. The axial direction of the first preset pivot 33 is perpendicular to the axial direction of the second preset pivot 23, and the axial direction of the second preset pivot 23 is parallel to the height direction of the foldable barbecue grill.

[0054] Among them, Figure 2 and Figure 3As shown, the second preset rotating shaft 23 has a first slot 231, the extension direction of which is parallel to the axial direction of the first preset rotating shaft 23. For example, the first slot 231 can be a metal sleeve, and is connected to the second preset rotating shaft 23 by welding.

[0055] See Figure 1 When the foldable barbecue grill is in the unfolded state, a portion of the structure (e.g., the end) of the first preset pivot 33 extends into the first slot 231. (See also...) Figure 6 When the foldable barbecue grill is in its folded storage state, the end of the first preset rotating shaft 33 disengages from the first slot 231. It is understood that the first sidewall 10 can contact the ground (support surface), and the second sidewall 20 is rotatably connected to the first sidewall 10 through multiple sleeves arranged in an overlapping manner. The sleeves on the first sidewall 10 can limit the sleeves on the second sidewall 20, preventing the second sidewall 20 from moving vertically. Furthermore, the second sidewall 20 can limit the bottom wall 30 through the first slot 231 and the first preset rotating shaft 33, preventing the bottom wall 30 from flipping around the first preset rotating shaft 33 when subjected to heat, thus improving structural reliability.

[0056] See Figure 4 The first preset rotating shaft 33 includes a sleeve, a telescopic rod, and a reset member. The outer circumferential surface of the sleeve is connected to the first base plate 31 and the second base plate 32. The telescopic rod and the reset member are disposed inside the sleeve, and at least a portion of the telescopic rod can extend out of the sleeve along the axial direction of the sleeve. The reset member is disposed inside the sleeve and connected to the telescopic rod, and is used to provide a reset force to the telescopic rod, so that the telescopic rod can extend out of the sleeve. In this embodiment, by making the first preset rotating shaft 33 telescopic, the first preset rotating shaft 33 can be easily inserted into or disengaged from the first slot 231 under external force (human push), reducing the difficulty of changing the shape of the foldable barbecue grill.

[0057] In one example, the sleeve contains two telescopic rods, and the reset element is a compression spring positioned between the two telescopic rods.

[0058] In some embodiments (not shown in the figures), the outer peripheral surface of the second preset rotating shaft has a protruding structure that protrudes from the surface of the second preset rotating shaft and extends along the heat source accommodating cavity. The end of the first preset rotating shaft has a second slot that is formed by the end face of the second preset rotating shaft being recessed inward in the axial direction. When the foldable barbecue grill is in the unfolded state, the protruding structure can extend into the second slot to form a fit.

[0059] In some embodiments, see Figure 2 When the foldable barbecue grill is in the unfolded state, the multiple foldable structures of the second side wall 20 are in a flat state.

[0060] In other embodiments, see Figure 4 When the foldable barbecue grill is in the unfolded state, the multiple relatively foldable structures of the bottom wall 30 are in a flat state.

[0061] In some other embodiments, see [reference] Figure 1 When the foldable barbecue grill is in the unfolded state, the multiple foldable structures of the second side wall 20 and the bottom wall 30 are all in a flat state.

[0062] In one exemplary embodiment, such as Figure 1 As shown, the foldable barbecue grill includes two opposing first side walls 10, multiple second side walls 20, and a bottom wall 30. The second side walls 20 and the bottom wall 30 are rotatably connected to the first side walls 10. When the foldable barbecue grill is in the unfolded state, the first side walls 10, the second side walls 20, and the bottom wall 30 are directly connected, and the first side walls 10, the second side walls 20, and the bottom wall 30 enclose and define a heat source accommodating cavity 40. When the foldable barbecue grill is in the stored state, the second side walls 20 and the bottom wall 30 are in the folded state, and the second side walls 20 and the bottom wall 30 are separated.

[0063] The foldable barbecue grill provided in this embodiment may include any structural components provided in the above embodiments.

[0064] like Figures 1 to 6 As shown, the foldable barbecue grill includes two U-shaped legs 50, which are respectively connected to two first side walls 10 to provide support for the first side walls 10. (See reference...) Figures 1 to 6 The U-shaped support leg 50 includes a crossbeam 51 and two support columns 52, located at both ends of the crossbeam 51. The first sidewall 10 and the second sidewall 20 are rotatably connected via the support columns 52. The crossbeam 51 is used to contact the ground and is connected to the first sidewall 10 and the second sidewall 20 via the two support columns 52. It can be determined that the U-shaped support leg 50 provided in this embodiment has a simple structure and can be formed by continuously bending metal columns or metal wires during the production process. The production method is simple, but it also provides support and connects the first sidewall 10 and the second sidewall 20, which is beneficial to realizing the portability of the foldable barbecue grill.

[0065] See Figure 1 Along the height direction of the foldable barbecue grill ( Figure 1 (as shown in the z-direction), the crossbeam 51, the support column 52, and the first side wall 10 enclose a clearance area 60, which is formed when the foldable barbecue grill is in the folded storage state (see...). Figure 6 The bottom wall 30 is flipped relative to the first side wall 10 and placed in the avoidance area 60.

[0066] In one example, see Figure 5 and Figure 6 The bottom wall 30 is composed of a first bottom plate 31 and a second bottom plate 32 of equal size. The distance between the crossbeam 51 and the first side wall 10 is equal to the width of the first bottom plate 31, so that the first bottom plate 31 can completely fill the clearance area 60, ensuring the aesthetics of the foldable barbecue grill in its folded storage state. In some alternative embodiments, the distance between the crossbeam 51 and the first side wall 10 can be greater than the width of the first bottom plate 31, so that when the foldable barbecue grill is in its folded storage state, the crossbeam 51 of the U-shaped support leg 50 can serve as a handle for the user to hold and carry.

[0067] Among them, Figure 2 and Figure 6 As shown, the end of the support column 52 away from the crossbeam 51 has a bend 53, and the bends 53 of the two supports 52 are arranged opposite to each other, with the bends 53 connected to the top of the first sidewall 10. In this embodiment, by providing bends 53 that can cooperate with the first sidewall 10, the U-shaped support leg 50 can be positioned vertically ( Figure 1 The first sidewall 10 is supported in the z-direction shown in the diagram.

[0068] Among them, Figure 1 As shown, the foldable barbecue grill also includes a barbecue rack 70, which is used to hold the food to be grilled.

[0069] See Figure 1 and Figure 2 The two U-shaped support legs 50 include a first support leg 50a and a second support leg 50b. One side of the grill rack 70 is rotatably connected to the two bends 53 of the first support leg 50a. When the foldable grill is in the unfolded state, the other side of the grill rack 70 overlaps the bends 53 of the second support leg 50b. When the foldable grill is in the folded state, the grill rack 70 can rotate and flip around the bends 53 of the first support leg 50a to the outside of the first side wall 10. The outside of the first side wall 10 is also the side of the two first side walls 10 that are opposite to each other, so that the grill rack 70 and the two first side walls 10 are stacked in sequence. The grill rack 70 provided in this embodiment has a simple structure, a simple assembly method, and a clever folding and storage method, which allows the foldable grill to be folded into a thin and light form for storage.
