Each of the plurality of pivoting connection slots comprises a first side wall and a second side wall arranged spaced apart from the first side wall. The plurality of connecting rods are pivotally connected between the first side wall and the second side wall. Because the plurality of pivoting connection slots are not provided with a locking structure, the plurality of connecting rods cannot be locked in place when in an unfolded position. Thus, existing canopies are easily subject to misoperation or easily affected by external forces to fold. There is a need for further improvement.

[0004] The technical solution disclosed in CN208669085U or U.S. Pat. No. 11,225,809B2, differs from the aforementioned existing canopies in that a pull rod is fixedly installed on the connection seat, and when unfolded, the upper end of the pull rod abuts the bottom surface of the top seat to maintain the unfolded state. Because the pull rod is added, the existing canopies have complex structures, not only is the use of space inside the canopy affected, but the pull rod occupies a large amount of space after packaging.

[0005] The technical solution disclosed in CN109667467A or U.S. Pat. No. 10,597,897B2 or CN207260738U or CN206110825U or U.S. Pat. No. 10,060,153B2, differs from the aforementioned existing canopies in that a stop rod is fixedly installed below the top seat, and the unfolded state is maintained by the stop rod abutting and locking the connection seat. This technical solution has a complex structure and inconvenient operation.

[0006] The technical solution disclosed in CN110725608B or U.S. Pat. No. 10,982,466B2, differs from the aforementioned existing canopies in that the canopy comprises a middle connection seat, a lower connection seat, an elastic member, and a first limiting mechanism. The middle connection seat and the lower connection seat are arranged up and down and can move away from or close to each other, and the elastic member is arranged between the middle connection seat and the lower connection seat to generate elastic force causing the middle connection seat and the lower connection seat to move away from each other.

Two ends of the long support rod are pivotally connected to the middle connection seat and a first canopy rod respectively, and two ends of the short support rod are pivotally connected to the lower connection seat and the long support rod respectively. An auxiliary unfolding mechanism comprises the middle connection seat, the lower connection seat, the elastic member, the first limiting mechanism, the long support rod, and the short support rod. Because the middle connection seat, the lower connection seat, the elastic member, and the first limiting mechanism are added, this technical solution has a complex structure.

[0007] The technical solution disclosed in CN114809794A, differs from the aforementioned existing canopies in that the canopy mechanism comprises an upper connection seat, a lower connection seat, and a plurality of canopy rod groups. The upper connection seat and the lower connection seat are arranged up and down, and two ends of each of the plurality of canopy rod groups are pivotally connected to the upper connection seat and the fixed seat respectively.

[0034] Referring to FIGS. 3, 9, 10, and 11, a top connecting mechanism 100 of a canopy comprises a connecting seat 10 and a plurality of connecting rods 20. The connecting seat 10 comprises a plurality of pivoting grooves 11 respectively pivotally connected to the plurality of connecting rods 20. Each of the plurality of pivoting grooves 11 comprises a first side wall 111 and a second side wall 112 arranged in parallel and spaced apart from each other. An end portion of each of the plurality of connecting rods 20 is pivotally connected to the first side wall 111 and the second side wall 112 of a corresponding one of the plurality of pivoting grooves 11, such as by a pivot (such as a rivet or a bolt) passing through the two side plates (i.e., the first side wall 111 and the second side wall 112) and a corresponding one of the plurality of connecting rods 20. Each of the plurality of pivoting grooves 11 comprises an elastic buckling column 113 and an abutting portion 115. A top end of the elastic buckling column 113 comprises a buckling protrusion 114. The abutting portion 115 and a pivoting line (i.e., the pivot) of the end portion of a corresponding one of the plurality of connecting rods 20 and a corresponding one of the plurality of pivoting grooves 11 are respectively arranged on two sides of the elastic buckling column 113. Each of the plurality of connecting rods 20 is configured to be rotated relative to the connecting seat 10 to be in an unfolded position, so that a bottom of each of the plurality of connecting rods 20 can be supported on the abutting portion 115 of the corresponding one of the plurality of pivoting grooves 11. The abutting portion 115 can inhibit a maximum expansion angle of the corresponding one of the plurality of connecting rods 20, which corresponds to the unfolded position. At this time, the canopy is in an unfolded state. The buckling protrusion 114 is buckled to a top of the corresponding one of the plurality of connecting rods 20, and the buckling protrusion 114 can prevent the corresponding one of the plurality of connecting rods 20 from rotating and folding in a reverse direction. The abutting portion 115 and the buckling protrusion 114 cooperate to keep the corresponding one of the plurality of connecting rods 20 in the unfolded position to achieve locking by buckling. The corresponding one of the plurality of connecting rods 20 will not be rotated and folded in the reverse direction without an external force (or a small external force generated by misoperation). An upper part and a lower part of the buckling protrusion 114 each comprise a guiding structure 1141, and the guiding structure 1141 can be a spherical structure. The guiding structure 1141 is convenient for locking the corresponding one of the plurality of connecting rods 20 into the unfolded position, and the guiding structure 1141 is convenient for folding the corresponding one of the plurality of connecting rods 20 in the reverse direction due to an external force operation.

[0035] Each of the plurality of pivoting grooves 11 has a first side plate 116 and a second side plate 117 arranged at intervals, and side walls of the first side plate 116 and the second side plate 117 facing each other define the first side wall 111 and the second side wall 112. A top of the second side wall 112 is a high-low stepped structure so as to have a high part 1121 and a low part 1122, and the low part 1122 and the high part 1121 are arranged in a front-and-rear direction. The elastic buckling column 113 is fixedly disposed on the low part 1122, a top wall of the high part 1121 is flush with a top of the buckling protrusion 114, and the structural layout is reasonable. When the corresponding one of the plurality of connecting rods 20 is in the unfolded position, the buckling protrusion 114 is buckled to a top of the corresponding one of the plurality of connecting rods 20. An inner side wall of the elastic buckling column 113 is arranged flush with the second side wall 112, and the buckling protrusion 114 protrudes relative to the inner side wall of the elastic buckling column 113, so as to improve stability and smoothness of a pivot connection and improve firmness of a buckling connection. Each of the plurality of pivoting grooves 11 has a groove bottom 118, and the first side plate 116 and the second side plate 117 are fixedly disposed on the groove bottom 118. The abutting portion 115 is fixedly disposed between a front end portion of the first side plate 116 and a front end portion of the second side plate 117 and protrudes from the groove bottom 118, and overall structural strength of the connecting seat 10 is high. Furthermore, the connecting seat 10 comprises a bottom plate 12, and the plurality of pivoting grooves 11 are fixedly disposed on the bottom plate 12. A portion of the bottom plate 12 located between the first side wall 111 and the second side wall 112 defines the groove bottom 118.

[0036] The plurality of pivoting grooves 11 are arranged in a circumferential annular array, and an extending direction of each of the plurality of pivoting grooves 11 is not arranged along a radial direction of the circumferential annular array. In this embodiment, the plurality of pivoting grooves 11 are four pivoting grooves 11, and adjacent two pivoting grooves 11 of the four pivoting grooves 11 are perpendicular to each other. A rear end of the first side plate 116 of a first one of the adjacent two pivoting grooves 11 is perpendicular to a middle of the first side plate 116 of a second one of the adjacent two pivoting grooves 11, and a structure is firm and has high strength. A handle 119 can also be fixedly connected to a lower side of the connecting seat 10 as needed to facilitate a user pushing up or pulling down the connecting seat 10.

[0037] Referring to FIGS. 1 to 11, the canopy comprises a plurality of columns 30, a top seat 40, a plurality of canopy rod assemblies, and a top connecting mechanism 100. A top of each of the plurality of columns 30 is fixedly disposed with a fixed seat 31, and each of the plurality of columns 30 is slidably disposed with a sliding seat 32. The fixed seats 31 and the sliding seats 32 of adjacent two columns 30 of the plurality of columns 30 are connected through a scissor mechanism assembly, and the scissor mechanism assembly comprises at least one scissor mechanism 33 (e.g., the scissor mechanism assembly can comprises at least two scissor mechanisms 33 connected in series). Each of the at least one scissor mechanism 33 comprises two second connecting rods 331 pivotally connected together at a middle position of the two second connecting rods 331. Each of the plurality of canopy rod assemblies comprises a first canopy rod 51 and a second canopy rod 52. A first end of the first canopy rod 51 is pivotally connected to the top seat 40. A first end of the second canopy rod 52 is pivotally connected to a second end of the first canopy rod 51, and a second end of the second canopy rod 52 is pivotally connected to the fixed seat 31. The connecting seat 10 is located below the top seat 40, and a second end portion of each of the plurality of connecting rods 20 is pivotally connected to a middle of a corresponding one of the first canopy rods 51. A supporting rod 34 is disposed between the second canopy rod 52 and the sliding seat 32. A lower end of the supporting rod 34 is pivotally connected to the sliding seat 32, and an upper end of the supporting rod 34 is pivotally connected to a middle of a corresponding one of the second canopy rods 52.

[0038] When unfolded, the connecting seat 10 is pushed upward to unfold the top connecting mechanism 100 and drive the entire canopy to open at the same time. The plurality of connecting rods 20 rotate around the pivots of the connecting seat 10 and push the buckling protrusions 114 of the elastic buckling columns 113 on the plurality of pivoting grooves 11. When the plurality of connecting rods 20 rotate to correspond to a position-limiting structure (i.e., the buckling protrusions 114) on the connecting seat 10 to be in the unfolded position, the plurality of connecting rods 20 are buckled by the buckling protrusions 114 of the elastic buckling columns 113 to achieve an interlocking connection, so that the canopy is unfolded to be in an unfolded state. Referring to FIGS. 1 to 5 and FIGS. 6 to 8, when the connecting seat 10 is pulled downward, the plurality of connecting rods 20 are separated from the buckling protrusions 114 of the elastic buckling columns 113 on the plurality of pivoting grooves 11, a locking state of the canopy is released, and the connecting seat 10 is pulled downward to fold the canopy to a folded state. Therefore, the present disclosure has the following advantages: 1. A single person can complete unfolding and folding operations of the canopy, saving time and effort; 2. The structure is simple, and it is convenient to produce; 3. The canopy is convenient and fast to use and has stable structure.

[0039] The above description is only a preferred embodiment of the present disclosure, and therefore should not be used to limit the scope of implementation of the present disclosure. That is, equivalent changes and modifications made according to the patent scope of the present disclosure and the contents of the specification should still fall within the scope covered by the present disclosure.

[0034] Referring to FIGS. 3, 9, 10, and 11, a top connecting mechanism 100 of a canopy comprises a connecting seat 10 and a plurality of connecting rods 20. The connecting seat 10 comprises a plurality of pivoting grooves 11 respectively pivotally connected to the plurality of connecting rods 20. Each of the plurality of pivoting grooves 11 comprises a first side wall 111 and a second side wall 112 arranged in parallel and spaced apart from each other. An end portion of each of the plurality of connecting rods 20 is pivotally connected to the first side wall 111 and the second side wall 112 of a corresponding one of the plurality of pivoting grooves 11, such as by a pivot (such as a rivet or a bolt) passing through the two side plates (i.e., the first side wall 111 and the second side wall 112) and a corresponding one of the plurality of connecting rods 20. Each of the plurality of pivoting grooves 11 comprises an elastic buckling column 113 and an abutting portion 115. A top end of the elastic buckling column 113 comprises a buckling protrusion 114. The abutting portion 115 and a pivoting line (i.e., the pivot) of the end portion of a corresponding one of the plurality of connecting rods 20 and a corresponding one of the plurality of pivoting grooves 11 are respectively arranged on two sides of the elastic buckling column 113. Each of the plurality of connecting rods 20 is configured to be rotated relative to the connecting seat 10 to be in an unfolded position, so that a bottom of each of the plurality of connecting rods 20 can be supported on the abutting portion 115 of the corresponding one of the plurality of pivoting grooves 11. The abutting portion 115 can inhibit a maximum expansion angle of the corresponding one of the plurality of connecting rods 20, which corresponds to the unfolded position. At this time, the canopy is in an unfolded state. The buckling protrusion 114 is buckled to a top of the corresponding one of the plurality of connecting rods 20, and the buckling protrusion 114 can prevent the corresponding one of the plurality of connecting rods 20 from rotating and folding in a reverse direction. The abutting portion 115 and the buckling protrusion 114 cooperate to keep the corresponding one of the plurality of connecting rods 20 in the unfolded position to achieve locking by buckling. The corresponding one of the plurality of connecting rods 20 will not be rotated and folded in the reverse direction without an external force (or a small external force generated by misoperation). An upper part and a lower part of the buckling protrusion 114 each comprise a guiding structure 1141, and the guiding structure 1141 can be a spherical structure. The guiding structure 1141 is convenient for locking the corresponding one of the plurality of connecting rods 20 into the unfolded position, and the guiding structure 1141 is convenient for folding the corresponding one of the plurality of connecting rods 20 in the reverse direction due to an external force operation.

[0035] Each of the plurality of pivoting grooves 11 has a first side plate 116 and a second side plate 117 arranged at intervals, and side walls of the first side plate 116 and the second side plate 117 facing each other define the first side wall 111 and the second side wall 112. A top of the second side wall 112 is a high-low stepped structure so as to have a high part 1121 and a low part 1122, and the low part 1122 and the high part 1121 are arranged in a front-and-rear direction. The elastic buckling column 113 is fixedly disposed on the low part 1122, a top wall of the high part 1121 is flush with a top of the buckling protrusion 114, and the structural layout is reasonable. When the corresponding one of the plurality of connecting rods 20 is in the unfolded position, the buckling protrusion 114 is buckled to a top of the corresponding one of the plurality of connecting rods 20. An inner side wall of the elastic buckling column 113 is arranged flush with the second side wall 112, and the buckling protrusion 114 protrudes relative to the inner side wall of the elastic buckling column 113, so as to improve stability and smoothness of a pivot connection and improve firmness of a buckling connection. Each of the plurality of pivoting grooves 11 has a groove bottom 118, and the first side plate 116 and the second side plate 117 are fixedly disposed on the groove bottom 118. The abutting portion 115 is fixedly disposed between a front end portion of the first side plate 116 and a front end portion of the second side plate 117 and protrudes from the groove bottom 118, and overall structural strength of the connecting seat 10 is high. Furthermore, the connecting seat 10 comprises a bottom plate 12, and the plurality of pivoting grooves 11 are fixedly disposed on the bottom plate 12. A portion of the bottom plate 12 located between the first side wall 111 and the second side wall 112 defines the groove bottom 118.

[0036] The plurality of pivoting grooves 11 are arranged in a circumferential annular array, and an extending direction of each of the plurality of pivoting grooves 11 is not arranged along a radial direction of the circumferential annular array. In this embodiment, the plurality of pivoting grooves 11 are four pivoting grooves 11, and adjacent two pivoting grooves 11 of the four pivoting grooves 11 are perpendicular to each other. A rear end of the first side plate 116 of a first one of the adjacent two pivoting grooves 11 is perpendicular to a middle of the first side plate 116 of a second one of the adjacent two pivoting grooves 11, and a structure is firm and has high strength. A handle 119 can also be fixedly connected to a lower side of the connecting seat 10 as needed to facilitate a user pushing up or pulling down the connecting seat 10.

[0037] Referring to FIGS. 1 to 11, the canopy comprises a plurality of columns 30, a top seat 40, a plurality of canopy rod assemblies, and a top connecting mechanism 100. A top of each of the plurality of columns 30 is fixedly disposed with a fixed seat 31, and each of the plurality of columns 30 is slidably disposed with a sliding seat 32. The fixed seats 31 and the sliding seats 32 of adjacent two columns 30 of the plurality of columns 30 are connected through a scissor mechanism assembly, and the scissor mechanism assembly comprises at least one scissor mechanism 33 (e.g., the scissor mechanism assembly can comprises at least two scissor mechanisms 33 connected in series). Each of the at least one scissor mechanism 33 comprises two second connecting rods 331 pivotally connected together at a middle position of the two second connecting rods 331. Each of the plurality of canopy rod assemblies comprises a first canopy rod 51 and a second canopy rod 52. A first end of the first canopy rod 51 is pivotally connected to the top seat 40. A first end of the second canopy rod 52 is pivotally connected to a second end of the first canopy rod 51, and a second end of the second canopy rod 52 is pivotally connected to the fixed seat 31. The connecting seat 10 is located below the top seat 40, and a second end portion of each of the plurality of connecting rods 20 is pivotally connected to a middle of a corresponding one of the first canopy rods 51. A supporting rod 34 is disposed between the second canopy rod 52 and the sliding seat 32. A lower end of the supporting rod 34 is pivotally connected to the sliding seat 32, and an upper end of the supporting rod 34 is pivotally connected to a middle of a corresponding one of the second canopy rods 52.

[0038] When unfolded, the connecting seat 10 is pushed upward to unfold the top connecting mechanism 100 and drive the entire canopy to open at the same time. The plurality of connecting rods 20 rotate around the pivots of the connecting seat 10 and push the buckling protrusions 114 of the elastic buckling columns 113 on the plurality of pivoting grooves 11. When the plurality of connecting rods 20 rotate to correspond to a position-limiting structure (i.e., the buckling protrusions 114) on the connecting seat 10 to be in the unfolded position, the plurality of connecting rods 20 are buckled by the buckling protrusions 114 of the elastic buckling columns 113 to achieve an interlocking connection, so that the canopy is unfolded to be in an unfolded state. Referring to FIGS. 1 to 5 and FIGS. 6 to 8, when the connecting seat 10 is pulled downward, the plurality of connecting rods 20 are separated from the buckling protrusions 114 of the elastic buckling columns 113 on the plurality of pivoting grooves 11, a locking state of the canopy is released, and the connecting seat 10 is pulled downward to fold the canopy to a folded state. Therefore, the present disclosure has the following advantages: 1. A single person can complete unfolding and folding operations of the canopy, saving time and effort; 2. The structure is simple, and it is convenient to produce; 3. The canopy is convenient and fast to use and has stable structure.

[0039] The above description is only a preferred embodiment of the present disclosure, and therefore should not be used to limit the scope of implementation of the present disclosure. That is, equivalent changes and modifications made according to the patent scope of the present disclosure and the contents of the specification should still fall within the scope covered by the present disclosure.
