[0031] Please refer to Figure 3 , Figure 9 , Figures 10 to 11, the top connection mechanism 100 of the awning, includes a connection seat 10 and several connecting rods 20. The connection seat 10 is provided with several pivot slots 11 for pivotally connecting the several connecting rods 20 respectively. The pivot slot 11 is provided with a first side wall 111 and a second side wall 112 arranged in parallel and spaced apart. The end of the connecting rod 20 is pivotally connected between the first side wall 111 and the second side wall 112, such as by a pivot shaft (such as a rivet or a bolt) passing through the two side plates and the connecting rod; the pivot slot 11 is further provided with an elastic clamping post 113 and an abutting portion 114. The top end of the elastic clamping post 113 is provided with a clamping protrusion 115. The abutting portion 114 and the pivot line (pivot shaft) of the end of the connecting rod 20 and the pivot slot 11 are respectively arranged on both sides of the elastic clamping post 113. The bottom of the connecting rod 20 rotating relative to the connection seat 10 in the unfolded position abuts against the abutting portion 114. The maximum unfolding angle of the connecting rod 20 is limited by the abutting portion 114, that is, in the unfolded position, the awning is in the unfolded state. The clamping protrusion 115 is clamped on the top of the connecting rod 20. The connecting rod 20 is prevented from reversing and folding by the clamping protrusion 115. The connecting rod 20 is held in the unfolded position by the cooperation of the abutting portion 114 and the clamping protrusion 115, that is, locking is achieved by clamping, and it will not reverse and fold without external force (or a small external force generated by misoperation). The clamping protrusion 115 is provided with guiding structures on both the upper and lower sides. The guiding structure is such as a spherical segment structure. The connecting rod is easily locked into the above-mentioned unfolded position through the guiding structure, and, reversely folded under the condition of external force operation.

[0032] The pivot slot 11 has a first side plate 116 and a second side plate 117 arranged in a spaced manner. The facing side walls of the first side plate 116 and the second side plate 117 constitute the above-mentioned first side wall 111 and second side wall 112; the top of the second side wall 112 is in a stepped structure with a high part and a low part. The low part and the high part are arranged front and back. The elastic clamping post 113 is fixedly arranged above the low part. The top wall of the high part is flush with the top of the clamping protrusion. The structural layout is reasonable. When the connecting rod is in the unfolded position, the clamping protrusion is clamped on the top of the connecting rod. The inner side wall of the elastic clamping post 113 is flush with the second side wall 112, and the clamping protrusion 115 protrudes relative to the inner side wall of the elastic clamping post 113, improving the stability and smoothness of the pivot connection and the firmness of the clamping. The pivot slot 11 also has a slot bottom 118. The first side plate 116 and the second side plate 117 are fixedly arranged on the slot bottom 118. The abutting portion 114 is fixedly arranged between the front ends of the first side plate 116 and the second side plate 117 and protrudes above the slot bottom 118. The overall structural strength of the connection seat is high. Further, the connection seat 10 is provided with a bottom plate, and several pivot slots 11 are fixedly arranged on the bottom plate. The part of the bottom plate located between the first side wall and the second side wall constitutes the above-mentioned slot bottom.

[0033] The plurality of pivot grooves 11 are arranged in a circumferential annular array, and the groove direction of the pivot grooves 11 is not arranged along the radial direction of the annular array. In this embodiment, four locking grooves 11 are provided, and two adjacent pivot grooves 11 are perpendicular to each other. The rear end of the first side plate 116 of one pivot groove 11 is perpendicular to the middle of the first side plate 116 of another pivot groove 11, and the structure is firm and has high strength. A handle 119 can also be fixed under the connection seat as needed to facilitate the user to push up or pull down the connection seat.

[0034] Please refer to Figures 1 to 11 The awning comprises a plurality of columns 30, a top seat 40, a plurality of awning rod assemblies and a top connection mechanism 100; a fixed seat 31 is fixed on the top of the column 30, and a sliding seat 32 is slidably connected to the column 30; a scissor mechanism group is connected between the fixed seat 31 and the sliding seat 32 of each two adjacent columns 30, and the scissor mechanism group includes at least one scissor mechanism 33 connected in series, and the scissor mechanism 33 includes two second connecting rods pivotally connected together in the middle; the awning rod assembly includes a first awning rod 51 and a second tent rod 52, one end of the first tent rod 51 is pivoted to the top seat 40, one end of the second tent rod 52 is pivoted to the other end of the first tent rod 51, and the other end of the second tent rod 52 is pivoted to the fixed seat 31; the connecting seat 10 is located under the top seat 40, and the other end of the connecting rod 20 is pivoted to the middle of the first tent rod 51; a support rod 34 is provided between the second tent rod 52 and the sliding seat 32, the lower end of the support rod 34 is pivoted to the sliding seat 32, and the upper end is pivoted to the middle of the second tent rod 52.

[0035] When unfolding, the connecting seat is pushed upward to open the top connecting mechanism 100 and drive the entire canopy to open. The connecting rod rotates around the connecting seat pivot and pushes the clamping protrusion 115 of the elastic clamping column on the pivot groove. When the connecting rod rotates to the limiting structure (expanded position) on the connecting seat, the clamping protrusion 115 of the elastic clamping column clamps the connecting rod to achieve limiting, so that the canopy is opened and the canopy is in the unfolded state; when the connecting seat is pulled downward, the connecting rod disengages the clamping protrusion 115 of the elastic clamping column on the pivot groove, releasing the locking state, and continuing to pull downward can fold the canopy to the folded state; please refer to Figures 1 to 5 , Figures 6 to 8 Therefore, it has the following advantages: 1. One person can open and fold the awning, saving time and effort; 2. Simple structure and convenient production; 3. Convenient and fast to use, and stable structure.

[0036] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope covered by the present invention.
