Description

Technical Field

[0001] The invention relates to camping supplies, in particular to an awning rack with an auxiliary unfolding mechanism. Background Art

[0002] Camping tents are generally divided into tents and awnings. The difference between the two lies in the upper and lower position relationship between the tarpaulin and the pole. The tent includes a tent frame (pole) and a tarpaulin, and the tarpaulin is connected under the tent frame. The awning includes an awning frame (pole) and a tarpaulin, and the tarpaulin is covered on the awning frame.

[0003] 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 fixedly provided on the top of the column, and a sliding seat 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 sliding seat, and the upper end is rotatably connected to the second awning rod. A scissor mechanism is also provided between the fixed seat and the sliding seat 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 sliding seat and the column of each column. Therefore, it has the following shortcomings: first, when folding, the locking mechanism of each column needs to be loosened, the steps are cumbersome, and it is inconvenient to open or fold; second, when opening, it is necessary to push the slide seat up relative to each column. In order to ensure that multiple columns push the slide seats 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.

[0004] In view of the above shortcomings, some people have proposed solutions, such as:

[0005] CN207714893U adds a bottom connection seat to the original awning frame, and a rotating rod is rotatably connected between each bottom connection seat and the first awning rod. 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 rod. A telescopic 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 awning frame is assisted in unfolding by the tension of the tension spring, and the distance between the bottom connection seat and the top connection seat is limited by the telescopic rod assembly being in the shortest position. By limiting the distance, the telescopic rod assembly, the rotating rod and the first awning rod form a triangular structure to keep the awning frame in the unfolded position.

[0006] US10060153 or CN109667467A adds a bottom connection seat, and a rotating rod is rotatably connected between each bottom connection seat and the first tent 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 tent pole, and a limiting rod is fixed under the top connection seat. When unfolded, the bottom connection seat passes 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. The distance is limited so that the telescopic rod assembly, the rotating rod and the first tent pole form a triangular structure to keep the tent frame in the unfolded position.

[0007] The above-mentioned awning frame is kept in an unfolded state by locking the distance between the top connecting seat and the bottom connecting seat, and has a complex structure and high cost. Summary of the invention

[0040] Embodiment 1

[0041] Please refer to Figures 1 to 13 The utility model discloses an awning frame with an auxiliary unfolding mechanism, comprising a top connecting seat 1 and a plurality of rack rod groups 2.

[0042] The rack rod set 2 includes a column 21, a tent rod set 22 and a support rod 23. The column 21 is a telescopic rod that can be extended (such as Figure 1 and Figure 2 As shown in the figure, a fixed seat 211 is fixed on the top of the column 21, and a slide seat 212 is slidably connected to the column 21, and the slide seat 212 can slide up and down relative to the column 21. The canopy rod group 22 includes a first canopy rod 221 and a second canopy rod 222. The inner end of the first canopy rod 221 is rotatably connected to the top seat 1, the inner end of the second canopy rod 222 is rotatably connected to the outer end of the first canopy rod 221, and the outer end of the second canopy rod 222 is rotatably connected to the fixed seat 211. The lower end of the support rod 23 is rotatably connected to the slide seat 212, and the upper end is rotatably connected to the second canopy rod 222.

[0043] A scissor mechanism 24 is rotatably connected between the fixed seat 211 and the sliding seat 212 of each two adjacent columns 21 , and the scissor mechanism 24 includes a plurality of scissor units 241 connected in series.

[0044] The awning frame also includes a middle seat 3, a lower seat 4, an elastic member 5, a first limiting mechanism 6 and a guide rod 7. The lower seat 4 is fixedly connected to the bottom of the guide rod 7, the middle seat 3 is located below the top seat 1, and the middle seat 3 can be slidably connected to the guide rod 7 and located above the lower seat 4, so that the middle seat 3 and the lower seat 4 are arranged up and down and can be separated or approached. The elastic member 5 includes a spring, which is sleeved outside the guide rod 7 and abuts between the lower seat 4 and the middle seat 3, so as to generate an elastic force that separates the middle seat 3 and the lower seat 4, and generates a thrust that can push the middle seat 3 to slide upward. The first limiting mechanism 6 limits the maximum distance between the middle seat 3 and the lower seat 4. In the specific structure, the first limiting member 71 is provided on the upper part of the guide rod 7 and the first limiting member at least partially protrudes from the side of the guide rod 7. The middle seat 3 is slidably sleeved outside the guide rod 7 and is located between the first limiting member and the lower seat 4. The middle seat 3 is pressed against the first limiting member to achieve the limiting. Further, the first limiting member 71 is a positioning pin fixedly connected to the guide rod 7. The positioning pin has a protruding portion protruding from the side of the guide rod. The limiting is achieved by the cooperation between the protruding portion and the middle seat. The rack rod group 2 also includes a long support rod 25 and a short support rod 26. The two ends of the long support rod 25 are respectively rotatably connected to the middle seat 3 and the first tent rod 221, and the two ends of the short support rod 26 are respectively rotatably connected to the lower seat 4 and the long support rod 25. The auxiliary deployment mechanism includes the above-mentioned middle seat 3, the lower seat 4, the elastic member 5, the first limiting mechanism 6, the guide rod 7, the long support rod 25 and the short support rod 26.

[0045] The column 21 is provided with a second limiting mechanism for limiting the sliding seat 212 from sliding upward to the highest position, and when the sliding seat 212 is at the highest position: the awning frame is in the unfolded state, the middle seat 3 abuts against the first limiting mechanism 6, and the middle seat 3 and the lower seat 4 are at the maximum distance. In this embodiment: the second limiting mechanism includes an increased portion 213 fixed on the sliding seat 212, and the increased portion 213 abuts against the fixed seat 211 to achieve limiting. In the specific structure: the increased portion 213 constitutes a sleeve portion of the sleeve column, and the increased portion and the sliding seat can be integrally formed. The above-mentioned increased portion can cooperate with the fixed seat to achieve limiting, and can also enhance the supporting strength, and is convenient for hand-held operation.

[0046] In this embodiment, the awning frame can be changed between the unfolded state and the folded state. The angle between the long support rod 25 and the middle seat 3 will pass through a dead point when the awning frame is changed between the unfolded state and the folded state. The dead point refers to an angle of 180 degrees. This setting can enhance the holding force of the awning frame in the unfolded state. Figure 6 When unfolded, the angle between the long support rod and the middle seat is rotated from less than 180 degrees to 181-190 degrees (such as 182 degrees), such as from less than 90 degrees or equal to 90 degrees or slightly greater than 90 degrees to 182 degrees.

[0047] In this embodiment, the distance between the rotation axis of the long support rod 25 and the first tent rod 221 and the outer end of the first tent rod 221 is shorter than the length of the long support rod 25, so that during the folding process, the middle seat, the lower seat, etc. are located below the first tent rod 221 (such as Figure 5 and Fig.13 As shown), the middle seat, the lower seat, etc. are prevented from interfering with the folding of the awning rod assembly.

[0048] The working principle of the awning frame of this embodiment is as follows: the thrust of the elastic member 5 (spring) pushes the middle seat 3 and the lower seat 4 apart, so that the long support rod 25 tends to open, and the long support rod 25 drives the first awning rod 221 to open, so that the user can save more effort in the process of opening the awning frame, and the elastic force of the elastic member 5 plays an auxiliary opening effect, that is, part of the force of opening or folding is applied by the elastic force; further, if the user opens the awning frame halfway, he can enter the middle of the awning frame and directly push the lower seat 4 upward, so that the awning frame can be opened more easily. When the awning is fully opened, the elastic member 5 (spring) is still in a certain compression state. Under the elastic force of the spring, there is always a certain force to prevent the awning frame from being folded, thereby effectively playing a role in stabilizing the awning, that is, even if the locking mechanism is omitted in the awning frame, the elastic force of the elastic member can keep the awning frame in the unfolded state. When the awning is to be folded, the awning can be folded by pulling the lower seat 4 downward with a certain force.

[0049] As needed, the rack rod group 2 also includes an eaves rod 27, the inner end of the eaves rod 27 is rotatably connected to the support rod 23, and the outer end passes through a through channel 215 provided on the fixed seat 211. When the awning frame is opened, the eaves rod 27 can be driven to partially extend out of the through channel 215 to form an eaves rod, and can be retracted when folded, so that little space is occupied after folding.

[0050] Embodiment 2

[0051] Please refer to Fig.14 The difference between the second limiting mechanism and the first embodiment is that: the second limiting mechanism includes a second limiting member 214 which is arranged on the column 21, located under the fixed seat 211 and protruding from the side of the column 21, and the limiting is achieved by the slide seat 212 pressing against the second limiting member 214. The second limiting member 214 is a positioning pin fixed to the column, and the positioning pin has an extending portion extending from the surface of the column, and the limiting is achieved by the cooperation between the slide seat 212 and the extending portion.

[0052] Embodiment 3

[0053] Please refer to Fig.15, which is different from the first embodiment in that: a third limiting mechanism is provided between the first awning rod 221 and the second awning rod 222 to limit the maximum upward lifting angle of the first awning rod and the second awning rod. Moreover, when the awning rack is at the maximum lifting angle: the awning rack is in the unfolded state, the middle seat 3 abuts against the first limiting mechanism 6, and the middle seat 3 and the lower seat 4 are at the maximum distance. The third limiting mechanism includes a rotating joint 223, and the first awning rod and the second awning rod are connected together through the rotating joint. In the specific structure, the rotating joint 223 includes a base body, and two connecting grooves 2231 are recessed on the top surface of the base body. The two connecting grooves 2231 are arranged in parallel, the right end of one connecting groove 2231 is connected to the right side wall of the base body, and the left end of the other connecting groove 2231 is connected to the left side wall of the base body. The first awning rod 221 and the second awning rod 222 are respectively placed in the two connecting grooves, and a rotating shaft 224 is provided to pass through the first awning rod, the second awning rod and the base body so that the first awning rod and the second awning rod can be rotatably connected to the rotating joint.

[0054] According to needs, the awning frame can select at least one of the second limiting mechanism and the third limiting mechanism.

[0055] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope 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 of the present invention.
