Description

Technical Field

[0001] The present invention relates to camping supplies, and particularly to a awning frame with an unfolding and maintaining mechanism. Background Art

[0002] Existing awning frames include a top connection seat and several pole groups. Each pole group includes a vertical pole, an awning pole group, and a support pole. A fixed seat is fixedly provided at the top end of the vertical pole, and a sliding seat is provided on the vertical pole. The awning pole group includes a first awning pole and a second awning pole. The inner end of the first awning pole is rotatably connected to the top connection seat, the inner end of the second awning pole is rotatably connected to the outer end of the first awning pole, and the outer end of the second awning pole is rotatably connected to the fixed seat. The lower end of the support pole is rotatably connected to the sliding seat, and the upper end is rotatably connected to the second awning pole. A scissor mechanism is further provided between the fixed seats and the sliding seats of every two adjacent vertical poles. The scissor mechanism includes at least one scissor unit. In order to keep the awning frame in the unfolded state, a locking mechanism needs to be provided between the sliding seat of each vertical pole and the vertical pole. Therefore, it has the following disadvantages: First, when folding, it is necessary to release the locking mechanism of each vertical pole, and the steps are cumbersome, making it inconvenient to open or fold; Second, when opening, it is necessary to push up the sliding seat relative to each vertical pole. In order to ensure that the sliding seats of multiple vertical poles are pushed up synchronously, it may require multiple people to operate together, and it is necessary to confirm whether each locking mechanism is in the locked state, and the steps are cumbersome, making it inconvenient to open or fold.

[0003] In view of the above deficiencies, some solutions have been proposed, for example:

[0004] CN207714893U adds a bottom connection seat to the original awning frame. A rotating rod is rotatably connected between each bottom connection seat and the first awning pole. One end of the rotating rod is rotatably connected to the bottom connection seat, and the other end is rotatably connected to the first awning pole. An expansion rod assembly is provided between the top connection seat and the bottom connection seat, and a tension spring is provided between the bottom connection seat and the top connection seat. The tension of the tension spring assists in unfolding the awning frame. By limiting the distance between the bottom connection seat and the top connection seat when the expansion rod assembly is in the shortest position, and by limiting this distance, the expansion rod assembly, the rotating rod, and the first awning pole form a triangular structure to keep the awning frame in the unfolded position.

[0005] US10060153 or CN109667467A adds a bottom connection seat. A rotating rod is rotatably connected between each bottom connection seat and the first awning pole. One end of the rotating rod is rotatably connected to the bottom connection seat, and the other end is rotatably connected to the first awning pole. A limiting rod is fixedly provided below the top connection seat. When unfolding, the bottom connection seat passes through the dead point, and the bottom connection seat abuts against the limiting rod to limit the distance between the bottom connection seat and the top connection seat. By limiting this distance, the expansion rod assembly, the rotating rod, and the first awning pole form a triangular structure to keep the awning frame in the unfolded position.

[0006] The applicant has applied for and publicly disclosed CN110725608A, which includes a top connection seat and a pole group. The pole group includes a vertical column and a awning pole group, and the awning pole group has a first awning pole. The awning frame includes a middle connection seat, a lower connection seat, an elastic member, and a first limiting mechanism; the pole group further includes a long support pole and a short support pole; the auxiliary unfolding mechanism includes the above-mentioned middle connection seat, lower connection seat, elastic member, first limiting mechanism, long support pole, and short support pole.

Specifically, a pivot 224 is provided to pass through the pivot hole and the push rod 24 to achieve rotation. The clearance space provides space for the second end of the push rod 24 to move. The rotation-limiting wall 223 limits the maximum rotation angle of the first end of the push rod 24 to rotate downward, that is, the unfolding angle. The pressure cover 42 presses upward against the second end 241 of the push rod 24 of the plurality of awning rod groups to keep the push rod at the unfolding angle. The push rods 24 of the plurality of awning rod groups are kept at the unfolding angle to keep the awning frame in the unfolded state. The downward angle of the push rods of at least one pair of the awning rod groups in the N awning rod groups at the unfolding angle is greater than 180 degrees. The gravity is used to cooperate with the angle greater than 180 degrees to achieve self-locking, thereby improving the stability and reliability of unfolding and maintaining.
