Description

Technical Field

[0001] This application relates to the field of tent technology, specifically to a folding frame for a tent and a tent. Background Technology

[0002] Tents are easy to carry when folded and provide shade and rain protection when unfolded, making them common equipment for camping or fieldwork. Common foldable tents are generally constructed from flexible, bendable poles connected by unidirectional hinge nodes at the ends, resembling biological joints. When unfolded, they present a centrally symmetrical, umbrella-like structure. However, the use of flexible poles limits their span and height. Currently, there are also solutions on the market that use series-parallel forked pole units to manufacture tents. For example, Chinese utility model patent CN222457000U discloses a foldable tent that uses several connecting seats, eccentric cross pole groups, and central cross pole groups to form a foldable and unfoldable tent. When unfolded, this tent has a semi-circular arched structure with a larger internal space. However, it suffers from a limited structural shape and cannot meet the diverse spatial requirements of fieldwork, emergency rescue, and military support scenarios. Utility Model Content

[0003] This application aims to address one of the technical problems in the related art to a certain extent. To this end, this application provides a folding frame for a tent and a tent itself.

[0004] To achieve the above objectives, this application adopts the following technical solution: a folding frame for a tent, the folding frame comprising:

[0005] The node mechanism is configured with multiple sets, each including a first node seat and a second node seat;

[0006] A first fork lever mechanism is provided, which includes multiple sets, each comprising two rotatably hinged first links, wherein the hinge point of the two first links is located at the midpoint of the first links; and,

[0007] The second fork lever mechanism is provided with multiple sets, each including two rotating hinged second rods. The second rods are of the same length as the first rods. The two second rods are symmetrical about their hinge points, and the position of the hinge points is offset from the midpoint of the second rods.

[0008] The folding bracket has a folded state and an unfolded state. In the unfolded state, the folding bracket has a width direction, a depth direction and a height direction. In any group of node mechanisms, the first node seat is located directly above the second node seat in the folded state. In the node mechanisms located on both sides along the depth direction, the first node seat and the second node seat are located on the same plane in the unfolded state.

[0009] Any two groups of node mechanisms arranged adjacent to each other along the depth direction are rotatably hinged to a first fork mechanism, and any two groups of node mechanisms arranged adjacent to each other along the width direction are rotatably hinged to a second fork mechanism.

[0010] When the folding bracket is in the unfolded state, the hinge points of the multiple sets of second fork mechanisms arranged sequentially along the height direction gradually move closer to or further away from the midpoint of the corresponding second rod.

[0011] The application of this application has the following beneficial effects: by setting a node mechanism, a first fork mechanism, and a second fork mechanism, the three work together to form a foldable support that can be folded and unfolded. In this application, the degree of deviation of the hinge point between the two second rods in some different groups of second fork mechanisms relative to the midpoint of the second rod is set to be different. This means that when the foldable support is in the unfolded state, the positions of the hinge points in the multiple groups of second fork mechanisms arranged sequentially along the height direction gradually move closer to or further away from the midpoint of the corresponding second rod. This allows the foldable support to take on an elliptical, parabolic, or other curved arched structure when unfolded, thereby meeting the needs of different spatial shapes in different usage scenarios. Similarly, based on this principle, the foldable support can also take on other curved shapes when unfolded.

[0012] Optionally, the number of node mechanisms arranged along the width direction is not less than three sets, and the number of node mechanisms arranged along the depth direction is not less than two sets.

[0013] Optionally, the first rod is provided with three first hinge holes in the same direction, two of which are located at both ends of the first rod and are symmetrically distributed with respect to the midpoint of the first rod, and the first hinge hole in the middle is located at the midpoint of the first rod; the second rod is provided with three second hinge holes in the same direction, two of which are located at both ends of the second rod and are symmetrically distributed with respect to the midpoint of the second rod, and the second hinge hole in the middle is offset from the midpoint of the second rod.

[0014] Optionally, the second rod has a first end and a second end, the first end being located below the second end along the height direction, and the second hinge hole located in the middle being between the midpoint of the second rod and the first end.

[0015] Optionally, both the first node seat and the second node seat include a chassis and multiple connecting plates disposed on the chassis, and both the first rod and the second rod are rotatably hinged to the connecting plates via pins.

[0016] Optionally, each chassis is provided with four connecting plates, which are symmetrically arranged at circumferential intervals.

[0017] Optionally, the node mechanism located in the middle along the width direction further includes a connecting structure disposed between the first node seat and the second node seat, the connecting structure being used to detachably fix the corresponding first node seat and the second node seat when the folding bracket is in the unfolded state.

[0018] Optionally, the connection structure includes a first connecting rod and a socket adapted to the first connecting rod, one of the first connecting rod and the socket being disposed on a first node seat and the other being disposed on a second node seat, the first node seat being detachably fixed to the second node seat by inserting the first connecting rod into the socket; or, the connection structure includes a first magnetic suction member and a second magnetic suction member, one of the first magnetic suction member and the second magnetic suction member being disposed on a first node seat and the other being disposed on a second node seat, the first node seat being detachably fixed to the second node seat by attracting the first magnetic suction member and the second magnetic suction member; or, the connection structure includes a first threaded rod disposed on a first node seat, a second threaded rod disposed on a second connecting seat, and a threaded sleeve disposed between the first threaded rod and the second threaded rod, the first node seat being detachably fixed to the second node seat by screwing the threaded sleeve onto the first threaded rod and the second threaded rod.

[0019] Furthermore, this application also provides a tent, including a tarpaulin, and the tent further includes a folding support as described in any of the above technical solutions, wherein one side surface of the tarpaulin is fixedly connected to the first node seat. The reasoning process for the beneficial effects of the tent provided in this application and the aforementioned folding support is similar, and will not be repeated here.

[0020] Optionally, the tent may further include a reinforcement component, which is disposed on the node mechanism and / or the first fork mechanism and is used for insertion and fixing to the ground.

[0040] This embodiment provides a folding frame for a tent, such as... Figure 1 , Figure 2 and Figure 3 As shown, the folding bracket includes a node mechanism 1, a first fork mechanism 2, and a second fork mechanism 3. The node mechanism 1 has multiple sets, each including a first node seat 10 and a second node seat 11. The first fork mechanism 2 has multiple sets, each including two rotatably hinged first rods 20, with the hinge point of the two first rods 20 located at the midpoint of the first rod 20. The second fork mechanism 3 has multiple sets, each including two rotatably hinged second rods 30, with the second rods 30 being of equal length to the first rods 20. The two second rods 30 are symmetrical about their hinge points, and the hinge points are offset from the midpoint of the second rods 30. Figure 3 The specific structure of the second link 30 is illustrated using the second fork mechanism 3 as an example. It is easy to understand that the first link 20 and the second link 30 in the first fork mechanism 2 have the same shape and dimensions; only the hinge points of the two first links 20 and the two second links 30 are different. Furthermore, Figure 1 A schematic diagram of the folding bracket is shown, where the cube represents node mechanism 1. The specific structure of node mechanism 1 will be explained later. Figure 7 and Figure 8 As shown in the image.

[0041] The folding bracket in this embodiment has a folded state and an unfolded state. Figure 1 and Figure 2 The image shows the unfolded and intermediate states of the folding bracket. In its unfolded state, the folding bracket has width, depth, and height dimensions. Specifically, Figure 1 Arrow X points in the width direction, arrow Y points in the depth direction, and arrow Z points in the height direction. When the folding bracket is in the folded state, the first node seat 10 in any set of node mechanisms 1 is directly above the second node seat 11. When the folding bracket is in the unfolded state, the first node seat 10 and the second node seat 11 in the node mechanisms 1 located at the two edges along the depth direction are on the same plane. That is, when the folding bracket is in the unfolded state, the first node seat 10 and the second node seat 11 in the node mechanisms 1 located at the two edges along the depth direction can simultaneously rest on the ground to provide stable support for the folding bracket.

[0042] like Figure 1 As shown, any two sets of adjacent node mechanisms 1 arranged along the depth direction are rotatably hinged to a first fork mechanism 2, and any two sets of adjacent node mechanisms 1 arranged along the width direction are rotatably hinged to a second fork mechanism 3. By setting the node mechanism 1, the first fork mechanism 2 and the second fork mechanism 3, the three cooperate to form a folding bracket that can be folded and unfolded.

[0043] In this embodiment, the positions of the hinge points on the two second rods 30 in the second fork mechanism 3 are designed so that, when the folding bracket is in the unfolded state, the positions of the hinge points in the multiple sets of second fork mechanisms 3 arranged sequentially along the height direction gradually move closer to or further away from the midpoint of the corresponding second rod 30. Specifically, as... Figure 3 As shown, the second rod 30 is provided with three unidirectional second hinge holes 300, wherein: two second hinge holes 300 are located at both ends of the second rod 30 and are symmetrically distributed with respect to the midpoint O of the second rod 30, while the second hinge hole 300 located in the middle is offset from the midpoint O of the second rod 30. The distance between the center of the second hinge hole 300 located in the middle and the midpoint O of the second rod 30 is denoted as D. The distance value D can characterize the degree to which the hinge point of the two second rods 30 deviates from the midpoint of the second rod 30. In this embodiment, the second rod 30 has a first end 301 and a second end 302. The first end 301 is located below the second end 302 along the height direction, and the second hinge hole 300 located in the middle is between the midpoint of the second rod 30 and the first end 301. Therefore, when the distance value D is larger, the position of the hinge point is farther from the midpoint of the second rod 30, and correspondingly, the position of the hinge point is closer to the first end 301.

[0044] Furthermore, in combination Figure 4 As shown, this embodiment uses a parabolic folding bracket as an example for explanation. For ease of description, the parabolic folding bracket is referred to as the parabolic bracket 5. Specifically, after unfolding, the parabolic bracket 5 has seven sets of second fork mechanisms 3 along the width direction X. For ease of description, the four sets of second fork mechanisms 3 arranged sequentially from low to high along the height direction Z are named the first height group 50, the second height group 51, the third height group 52, and the fourth height group 53, respectively. The aforementioned "when the folding bracket is in the unfolded state, the positions of the hinge points in the multiple sets of second fork mechanisms 3 arranged sequentially along the height direction gradually move away from the midpoint of the corresponding second rod 30" refers to the fact that the spacing value D in the first height group 50, the second height group 51, the third height group 52, and the fourth height group 53 gradually increases. Figure 5 As shown, in this case, a parabolic support 5 is obtained. Compared with the semi-circular support 8 in the prior art, the parabolic support 5 shown in this embodiment can achieve a larger size when the same number of second fork mechanisms 3 are set.

[0045] Similarly, the aforementioned statement that "when the folding bracket is in the unfolded state, the hinge points of the multiple sets of second fork mechanisms 3 arranged sequentially along the height direction gradually move closer to the midpoint of the corresponding second rod 30" refers to the gradual decrease of the spacing value D in the first height group 50, the second height group 51, the third height group 52, and the fourth height group 53. In this case, the following can be obtained: Figure 6 The elliptical folding bracket shown is referred to as the elliptical bracket 4 in this embodiment for ease of description. Compared to the semi-circular bracket 8 in the prior art, the elliptical bracket 4 shown in this embodiment can achieve a larger span when the same number of second fork mechanisms 3 are set.

[0046] Therefore, in this embodiment, by setting different degrees of deviation between the hinge points of two second rods 30 in some different groups of second fork mechanisms 3 relative to the midpoint of the second rod 30, the hinge points in the multiple groups of second fork mechanisms 3 arranged sequentially along the height direction gradually move closer to or further away from the midpoint of the corresponding second rod 30 when the folding bracket is in the unfolded state. This allows the folding bracket to present an elliptical arched structure or a parabolic arched structure when unfolded, thereby meeting the needs of different spatial shapes in different usage scenarios. Similarly, based on this principle, the folding bracket can also present other curved shapes when unfolded.

[0047] It should be noted that the dimensions of the first member 20, the second member 30, and the various spacing values ​​D can be designed according to the optimization design scheme. By setting optimization objectives and constraints, the above-mentioned dimensional values ​​can be determined through existing optimization design methods. This design process can be completed through existing optimization design methods, and will not be elaborated here.

[0048] In this embodiment, the number of node mechanisms 1 arranged along the width direction X is eight, and the number of node mechanisms 1 arranged along the depth direction Y is six. Correspondingly, in this embodiment, the number of second fork mechanisms 3 arranged along the width direction X is seven, and the number of first fork mechanisms 2 arranged along the depth direction Y is five. In other optional embodiments, the number of node mechanisms 1 arranged along the width direction is not less than three, and the number of node mechanisms 1 arranged along the depth direction is not less than two.

[0049] Similar to the structure of the second member 30, the first member 20 in this embodiment is provided with three first hinge holes in the same direction. Two of the first hinge holes are located at the two ends of the first member 20 and are symmetrically distributed relative to the midpoint of the first member 20. The first hinge hole in the middle is located at the midpoint of the first member 20.

[0050] like Figure 6 and Figure 7 As shown, in this embodiment, both the first node seat 10 and the second node seat 11 include a chassis 12 and multiple connecting plates 13 disposed on the chassis 12. The first rod 20 and the second rod 30 are rotatably hinged to the connecting plates 13 via pins. Furthermore, in this embodiment, each chassis 12 is provided with four connecting plates 13, which are symmetrically arranged at circumferential intervals. This structural arrangement facilitates the hinged assembly of a single first node seat 10 or a single second node seat 11 with the corresponding multiple first rods 20 or second rods 30, avoiding interference between the first rods 20 or second rods 30 installed on the same set of node mechanisms 1. Furthermore, the cross-shaped arrangement of the four connecting plates 13 improves the structural strength of the first node seat 10 and the second node seat 11.

[0051] It should be noted that, Figure 7 , Figure 8 and Figure 9 The diagram shows an embodiment where the chassis 12 has a circular, grooveless structure, which is simple to manufacture and has a lower cost. Figure 12 The diagram shows an embodiment where the chassis 12 has a square grooved structure, which provides better structural strength.

[0052] Combination Figure 1 and Figure 9As shown, when the folding bracket is fully unfolded, it can be stabilized by connecting the first node seat 10 and the second node seat 11 in part of the node mechanism 1. In this embodiment, the node mechanism 1 located in the middle along the width direction X also includes a connecting structure disposed between the first node seat 10 and the second node seat 11. The connecting structure is used to fix the corresponding first node seat 10 and second node seat 11 when the folding bracket is in the unfolded state. It is easy to understand that the connecting structure of the fixed first node seat 10 and the second node seat 11 needs to be disassembled before the folding operation.

[0053] The connection structure in this embodiment includes a first connecting rod 14 and a socket adapted to the first connecting rod 14. In this embodiment, the first connecting rod 14 is provided on the first node seat 10, and a socket adapted to the first connecting rod 14 is provided on the second node seat 11. In other optional embodiments, the first connecting rod 14 and the socket can be respectively provided on the second node seat 11 and the first node seat 10. Specifically, in this embodiment, the first connecting rod 14 is rotatably hinged to the first node seat 10, and a second connecting rod 15 is rotatably hinged to the second node seat 11. The socket is provided at the end of the second connecting rod 15 facing the first connecting rod 14. The end of the first connecting rod 14 facing the second connecting rod 15 is detachably plugged into the socket on the second connecting rod 15. It is easy to understand that a slot can also be provided on the end of the first connecting rod 14 facing the second connecting rod 15. Correspondingly, a plug that matches the aforementioned slot is provided on the inner wall of the insertion port at the end of the second connecting rod 15. Thus, a male and female plug structure is formed on the opposite ends of the first connecting rod 14 and the second connecting rod 15, which can improve the plug-in firmness.

[0054] It should be noted that connection structures can be set for all node mechanisms 1 located in the middle along the width direction X, or for only some node mechanisms 1 located in the middle along the width direction X. Furthermore, in use, the first connecting rod 14 and the second connecting rod 15 of all the connection structures can be connected together, or only the first connecting rod 14 and the second connecting rod 15 of some of the connection structures can be connected together. From the principle of structural design, only one set of connection structures in node mechanisms 1 is needed to connect the first node seat 10 and the second node seat 11 to maintain a certain stability of the folding bracket. It is easy to understand that the more connection structures are set and used, the better the stability of the folding bracket in the unfolded state. In practical applications, the usage of the connection structures can be determined according to the stress conditions of the tent in the usage environment (whether it is windy, rainy, snowy, etc.).

[0055] In other alternative embodiments, the connection structure may also include a first magnetic attractor and a second magnetic attractor, one of which is disposed on the first node seat 10 and the other on the second node seat 11. The first node seat 10 is detachably fixed to the second node seat 11 by the attraction of the first magnetic attractor and the second magnetic attractor. Alternatively, the connection structure may also include a first threaded rod disposed on the first node seat 10, a second threaded rod disposed on the second connecting seat, and a threaded sleeve disposed between the first threaded rod and the second threaded rod. The first node seat 10 is detachably fixed to the second node seat 11 by screwing the threaded sleeve onto the first threaded rod and the second threaded rod.

[0056] like Figure 10 and Figure 11 A tent using the folding frame provided in this embodiment is shown. The tent includes a tent fabric 6 and a folding frame, with one side surface of the tent fabric 6 fixedly connected to a first node seat 10. The tent fabric 6 may include a top cover and side covers, and the entire tent fabric 6 covers the top and four sides of the folding frame, forming a closed covering structure. Optional zipper openings may be provided on the four sides of the tent fabric 6 to facilitate entry and exit from the tent. The tent fabric 6 can be fixed to the first node seat 10 by means of bolt connection, Velcro fastening, snap fastening, or strap binding.

[0057] The design ensures that the tarpaulin 6 meets the following requirements: the positions on the tarpaulin 6 used for connecting with the first node seat 10 are designated as connection points, and the positions of each connection point correspond to the positions of each first node seat 10 when the folding support is in the unfolded state. This ensures that the spacing between adjacent connection points is the same as the spacing between their corresponding first node seats 10, allowing the tarpaulin 6 to automatically tension and form a "skin effect" when the folding support is in the unfolded state. Thus, the tarpaulin 6, in its tensioned state, not only provides shelter but also acts like a cable under external loads, forming a collaborative working system with the folding support. This effectively improves the overall structural rigidity and stability, reduces reliance on rigid members, and lowers the system's self-weight.

[0058] Furthermore, such as Figure 12As shown, the tent in this embodiment also includes a reinforcing component 7, specifically a ground peg. The ground peg can be selectively mounted on the node mechanism 1 and the first fork mechanism 2 near the ground, reinforcing the tent by inserting it into the ground. It is easy to understand that when mounting the reinforcing component 7 onto the node mechanism 1, it can be mounted on either the first node seat 10 or the second node seat 11. Furthermore, one end of the ground peg is inserted into the ground, and the other end can be provided with a hook-shaped connecting part as needed. The connecting plate 13 in the node mechanism 1 is provided with a connecting hole for rotatably hinged to the first rod 20 or the second rod 30. The ground peg can either pass through the connecting hole and be inserted into the ground, or it can be hung on the first rod 20 and inserted into the ground via the hook-shaped connecting part.

[0059] The tent can be set up and folded down by a single operator. Specifically, when setting up the tent, the operator first pulls the folding frame along the width direction (X) to unfold it simultaneously along both the width and depth directions. This operation causes the first rod 20 and the second rod 30 to rotate around their respective three hinge points. As this operation continues, when the included angle between the two first rods 20 and the two second rods 30 in the first fork mechanism 2 and the second fork mechanism 3 gradually reaches approximately 90°, the folding frame is nearly flattened. At this point, the horizontal pulling operation is completed, and the frame unfolds from its folded state to its flattened state. Figure 2 The intermediate state is shown. Then, the operator applies an upward thrust near the center of the folding bracket, causing the first node seats 10 and second node seats 11 located in the center to rise in tandem. The folding bracket further unfolds synchronously along the width, depth, and height directions until it transforms into the intermediate state shown. Figure 1 The design shown is in its unfolded state, with the integrated tarpaulin unfolding synchronously with the folding support during the process. The entire process requires only simple horizontal pulling and upward pushing by the operator. Finally, the first node seat 10 and the second node seat 11 are connected via a connecting structure, and ground stakes are inserted into the ground to complete the entire unfolding and erection operation.

[0060] It is easy to understand that the process of unpacking and folding is simply the reverse of the above operations, which will not be elaborated here.

[0061] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Those skilled in the art should understand that this application includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this application will be included within the scope of the claims.
