Description

Technical Field

[0001] The present invention relates to camping supplies, in particular to an awning rack. Background Art

[0002] The existing awning frame includes a top connection seat and a plurality of frame rod groups. The frame rod group includes a column, a awning rod group and a strut. A fixed seat is fixed on the top of the column, and a slide is provided on the column. The awning rod group includes a first awning rod and a second awning rod, the inner end of the first awning rod is rotatably connected to the top connection seat, the inner end of the second awning rod is rotatably connected to the outer end of the first awning rod, and the outer end of the second awning rod is rotatably connected to the fixed seat. The lower end of the strut is rotatably connected to the slide, and the upper end is rotatably connected to the second awning rod. A scissor mechanism is also provided between the fixed seat and the slide of each adjacent column, and 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 slide and the column of each column. Therefore, it has the following shortcomings: first, when folding, it is necessary to loosen the locking mechanism of each column, the steps are cumbersome, and it is inconvenient to open or fold; second, when opening, it is necessary to push the slide up relative to each column. In order to ensure that multiple columns push the slide up synchronously, multiple people may be required to operate together, and it is necessary to confirm whether each locking mechanism is in a locked state, the steps are cumbersome, and it is inconvenient to open or fold.

[0003] In response to the above shortcomings, some people have proposed solutions, such as:

[0004] CN207714893U adds a base connector to the existing awning frame. A rotating rod is rotatably connected between each base connector and the first awning rod. One end of the rotating rod is rotatably connected to the base connector and the other end is rotatably connected to the first awning rod. A telescopic rod assembly is provided between the top and bottom connectors, and a tension spring is provided between the bottom and top connectors. The tension of the tension spring assists in the awning frame's deployment. The telescopic rod assembly is in its shortest position, which defines the spacing between the base and top connectors. This defined spacing allows the telescopic rod assembly, rotating rod, and first awning rod to form a triangular structure, maintaining the awning frame in its deployed position.

[0005] US10060153 or CN109667467A adds base connectors. A rotating rod is rotatably connected between each base connector and the first awning pole. One end of the rotating rod is rotatably connected to the base connector, and the other end is rotatably connected to the first awning pole. A limiting rod is fixed below the top connector. When deployed, the base connector passes through dead center and abuts against the limiting rod, defining the spacing between the base connector and the top connector. This spacing is limited, allowing the telescopic rod assembly, rotating rod, and first awning pole to form a triangular structure, maintaining the awning frame in the deployed position.

[0006] CN110725608A, filed and published by the applicant, comprises a top connector and a pole assembly. The pole assembly comprises a column and a canopy pole assembly, which includes a first canopy pole. The canopy frame comprises a middle connector, a lower connector, an elastic member, and a first limiting mechanism; the pole assembly also comprises a long support pole and a short support pole; and the auxiliary deployment mechanism comprises the aforementioned middle connector, lower connector, elastic member, first limiting mechanism, long support pole, and short support pole.

[0037] Example 1

[0038] Please refer to Figures 1 to 7 The awning frame includes N columns 1 and a canopy mechanism 2, where N is a natural number greater than or equal to 3. The top of the column 1 is fixed with a fixed seat 11, and a slide 12 is slidably connected to the column 1. The column 1 is provided with a third limiting mechanism for limiting the slide 12 from sliding upward to the highest position. The third limiting mechanism can be Figure 2 、 3 The limiting ring 13 fixed on the column can also be a locking mechanism that directly locks the slide 12 at a predetermined height. The locking mechanism can be a snap lock or a latch lock, etc.; the N columns 1 are arranged in a ring structure, such as a rectangle, a hexagon, etc., and a scissor mechanism 3 is connected between the fixed seat 11 and the slide 12 of each two adjacent ring columns 1. The scissor mechanism 3 includes a plurality of serially connected scissor units 31, and the scissor unit 31 includes two support rods rotatably connected together in the middle, and the end of the support rod of the outermost scissor unit 31 is rotatably connected to the slide or fixed seat, so that the N columns can be retracted or opened toward the center of the ring.

[0039] The canopy mechanism 2 includes an upper connecting seat 21, a middle connecting seat 22, a lower connecting seat 23, N canopy pole groups, a first limiting mechanism and a second limiting mechanism; the upper connecting seat 21, the middle connecting seat 22 and the lower connecting seat 23 are all provided with N connecting nests arranged at circumferential annular intervals, and the upper connecting seat 21, the middle connecting seat 22 and the lower connecting seat 23 are arranged in the upper, middle and lower positions. The two ends of the canopy pole group are respectively connected to the upper connecting seat 21 and the fixed seat 11, and a canopy pole group is provided between the fixed seat 11 and the upper connecting seat 21 of each column 1.

[0040] The awning rod assembly includes a first awning rod 24, a second awning rod 25, a support rod 26, a push rod 27, and a connecting rod 28. The inner end of the first awning rod 24 is pivotally connected to the connection socket of the upper receiving seat 21. The inner end of the second awning rod 25 is pivotally connected to the outer end of the first awning rod 24. The second awning rod 25 is pivotally connected to the fixed seat 11. The outer end of the second awning rod 25 is pivotally connected to the fixed seat 11, and the outer end of the second awning rod 25 can extend outside the fixed seat 11 as needed. The lower end of the support rod 26 is pivotally connected to the sliding seat 12, and the upper end is pivotally connected to the middle of the second awning rod 25. The first end of the push rod 27 is connected to the middle of the first awning rod 24, and the second end is connected to the connection socket of the lower receiving seat 23. The first end of the connecting rod 28 is connected to the middle of the push rod 27, and the second end is connected to the connection socket of the middle receiving seat 22. The first limiting mechanism cooperates with the middle connecting seat 22 and the lower connecting seat 23 and limits the minimum distance between the middle connecting seat 22 and the lower connecting seat 23; the second limiting mechanism limits the maximum upward rotation angle of the connecting rod 28, and the end of the connecting rod 28 at the maximum rotation angle is arranged tilted upward. Through the above-mentioned first limiting mechanism and second limiting mechanism, when the awning frame is in the unfolded state, the downward angle A of the connecting rod 28 relative to each of the two awning rod groups is greater than 180 degrees (such as 181-200 degrees, such as 187 degrees), such as Figure 1 、 5 As shown in Figures 7 and 8, the self-locking is achieved by utilizing the angle greater than 180 degrees, and the unfolded state is maintained by self-locking. The unfolding is stable and reliable, and the unfolding is labor-saving, convenient and fast.

[0041] The first limiting mechanism includes a push rod 221 fixedly mounted below the middle connector 22. The push rod 221 abuts against the top surface of the lower connector 23 to achieve position limiting. Unless the middle connector 22 is manually lifted, the first limiting mechanism will remain in the limited position under the action of gravity (the push rod 221 abuts against the top surface of the lower connector 23, at which point there is a certain height difference between the connection between the middle connector and the connecting rod and the connection between the lower connector and the push rod). The second limiting mechanism remains in the deployed state. If desired, the push rod can be omitted. The middle connector 22 itself has a certain height and abuts directly against the lower connector 23, utilizing this height to achieve a certain height difference between the connection nest of the middle connector and the connection nest of the lower connector.

[0042] The second limiting mechanism connects the central seat 22 and the connecting rod 28. This second limiting mechanism includes a rotation-limiting wall 222 located within a connection nest within the central seat 22. The connection nest and the rotation-limiting wall cooperate to limit the maximum upward rotation angle of the connecting rod 28. Specifically, the central seat 22 is recessed with the connection nest, and the bottom wall of the connection nest forms the rotation-limiting wall 222. In this embodiment, the second limiting mechanism is located between the central seat 22 and the connecting rod 28 to directly limit the maximum rotation angle of the connecting rod. However, it can also be located elsewhere, such as between the lower seat and the push rod, as needed.

[0043] As needed, the awning rod group also includes an eaves rod 29, the inner end of the eaves rod 29 is rotatably connected to the support rod 26, and the outer end passes through a through-channel provided on the fixed seat 11. When the awning frame is opened, the eaves rod 29 can be driven to partially extend out of the through-channel to form the eaves rod, and can be retracted when folded, so that it occupies less space after folding.

[0044] Please refer to Figures 1 to 6 During the opening process, N columns 1 are unfolded from the center outward, the slide 12 slides upward to the third limit mechanism, the top rod 221 of the middle seat 22 presses against the lower seat 23, and the connecting rod 28 rotates upward to the maximum rotation angle, that is, the first and second limit mechanisms are in the limit state. At this time, the downward angle of the connecting rod 28 of each relative two awning pole groups is greater than 180 degrees (such as 187 degrees). Figure 1 、 5 As shown in Figures 7 and 8, the self-locking is achieved by utilizing the angle greater than 180 degrees, and the tent is kept in the unfolded state by self-locking. The unfolding is stable and reliable, and the unfolding requires little effort, making the unfolding convenient and quick. During the folding process, first, the middle connecting seat 22 is lifted upwards so that the downward angle of the connecting rod 28 of each relative pair of tent pole groups is less than 180 degrees. At this time, the self-locking is unlocked, and the unlocking requires little effort, making the unlocking convenient. Then, the N uprights 1 are moved from the outside to the center, and the slide 12 slides downwards until it is in the folded state. The folding requires little effort, and the folding is convenient and quick.

[0045] Example 2

[0046] Please refer to Figure 8 The difference between the embodiment 1 and the embodiment 2 is that the first end of at least one connecting rod 28 in the plurality of awning pole groups extends outward and forms an operating handle 281. Pressing the operating handle 281 can lift the middle connecting seat 22 to unlock the awning, making unlocking more convenient and quick. Moreover, after being folded, the operating handle 281 is also folded to the side of the first awning pole, making the structure compact.

[0047] Example 3

[0048] Please refer to Figure 9 This embodiment differs from the first embodiment in that the lower connecting seat 23 is provided with a movable member that can move relative to the lower connecting seat 23. The movable member controls whether to lift the top rod of the middle connecting seat 22 upward, so that the downward angle of the connecting rod 28 relative to each of the two tent rod groups is less than 180 degrees, thereby achieving unlocking. In the specific structure, the movable member includes a slide and a driving member 231. The lower connecting seat 23 is provided with a sliding hole 232 extending vertically therethrough. The slide can be slidably connected to the sliding hole 232. The driving member 231 can be rotatably connected below the lower connecting seat 23. The lower end of the slide abuts the top surface of the driving member 231, and the rotation of the driving member 231 drives the slide to slide up and down. Furthermore, the top surface of the driving member can be provided with a cam surface to drive the slider. Of course, other transmission structures can also be used. As needed, the movable member can also adopt other movement methods, such as swinging, so that it abuts the top rod.

[0049] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of the present invention. In other words, equivalent changes and modifications made according to the scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
