Description

Technical Field

[0001] The present application relates to the field of tent structures, and in particular to a tent support structure and a tent. Background Art

[0002] When tents or awnings are unfolded or folded, the foot poles will also be folded and unfolded. The foot poles are generally composed of multiple hinged support rod units. During the folding and unfolding process, each adjacent support rod unit will swing relative to each other. Therefore, the stability of the connection between adjacent support rod units after unfolding is crucial.

[0003] Through understanding the relevant technologies, we find that some tents or canopy products are cumbersome to unfold, and there are also problems with stability and insufficient supporting strength. Summary of the invention

[0004] The purpose of at least one specific embodiment of the present invention is to solve the defects of the prior art and provide a tent support structure.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A tent support structure, comprising: Connecting rod; A support rod, comprising a first support rod and a second support rod hinged to each other, wherein one end of the second support rod is hinged to the connecting rod; It also includes: A connecting member, two ends of which are connected to the first support rod and the connecting rod respectively; the first support rod, the second support rod, the connecting rod, and the connecting member together form a variable area; When the tent support structure stretches from a folded state to an unfolded state, the variable region changes from an unstable quadrilateral shape to a stable triangular shape, and during the shape change process, the connecting member is allowed to deform.

[0006] Furthermore, the connecting member is composed of at least two rigid components hinged to each other, and two ends of the connecting member are respectively hinged to the first support rod and the connecting rod; During the transformation from a quadrilateral to a triangle, the connector is adapted to change the angle between the rigid components to adapt to the change in the structural morphology.

[0007] Furthermore, when the tent support structure is in a fully unfolded state, the multiple rigid components of the connecting member are straightened and aligned in a collinear manner to rigidly support the connecting rod on the first supporting rod.

[0008] Furthermore, the connecting member is a flexibly deformable elastic rope; when the shape of the variable area changes, the elastic rope is suitable for generating tension to restrict the rotation of the first support rod and the connecting rod.

[0009] Furthermore, when the tent support structure is in a fully unfolded state, the elastic rope is in a stretched state, so as to generate a downward pulling force on the connecting rod along the axial direction of the elastic rope.

[0010] Further, when the first support rod rotates to be located on the same straight line as the second support rod, the variable area completes the change from the unstable quadrilateral shape to the stable triangular shape.

[0011] Further, when the first support rod is rotated to be located on the same straight line as the second support rod, the two are suitable for locking with each other to form a linear support.

[0012] Further, a locking portion is provided at the end of the first support rod or the second support rod; When the first support rod rotates to be located on the same straight line as the second support rod, the locking portion is self-locked with the rod portion of another support rod opposite thereto.

[0013] Furthermore, the locking portion includes a locking groove and a locking element at least partially located in the locking groove, and the slot opening direction of the locking groove is opposite to the rod portion of the other support rod, so that when the first support rod and the second support rod are self-locked, the locking groove receives and wraps the rod portion, and is locked with the rod portion through the locking element.

[0014] The tent support structure provided by the present application has the following beneficial technical effects compared with the prior art: During the unfolding process of the tent support, the variable area changes from an unstable quadrilateral shape to a stable triangular shape. The triangle is a stable geometric shape with unique advantages in mechanical structure. When the variable area forms a triangle, the stability of its structure is greatly enhanced. Compared with the characteristic of easy deformation of the quadrilateral structure, the triangular structure can better resist external force, so that the tent support can maintain a stable shape when bearing the weight of the tent and the external environmental force (such as wind, vibration, etc.), reducing the possibility of shaking and deformation.

[0015] In addition, the connectors are allowed to deform during the morphological change, and this deformation property cooperates with the change of the structural morphology to help achieve a smoother transition. In the process of changing from a quadrilateral to a triangle, the connectors can adapt to the movement of other parts and the transmission of force, making the change of the entire structure more natural and stable.

[0016] In addition, the invention also relates to a tent based on the tent support structure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] This application involves three aspects of technical content, which will be explained in detail below.

[0021] First aspect: regarding the self-locking component 40.

[0022] Reference Figure 1 and Figure 2 As shown, a tent support structure comprises: Pan head 10; A connecting rod 20, one end of which is movably connected to the pan head 10; The support rod 30 includes a first support rod 301 and a second support rod 302 which are hinged to each other, and one end of the second support rod 302 is hinged to the connecting rod 20; The self-locking assembly 40 includes a locking portion 401 located on the first support rod 301 or the second support rod 302; The self-locking component 40 is arranged on the movement path of the movable hinge of the first support rod 301 and the second support rod 302, and is suitable for the locking portion 401 to self-lock with the rod portion of the other support rod 30 opposite to it when the first support rod 301 is rotated to be on the same straight line L1 as the second support rod 302, so as to lock the first support rod 301 and the second support rod 302 to form a linear support.

[0023] Specifically, in Figures 1 to 3 In the embodiment shown, the locking portion 401 is located on the first support rod 301. When the first support rod 301 rotates to be on the same straight line L1 as the second support rod 302, as shown in FIG. Figure 3 As shown, the locking portion 401 and the rod portion 3021 of the second support rod 302 are self-locked to lock the first support rod 301 and the second support rod 302 to form a linear support.

[0024] The self-locking function of the technical solution makes the process of setting up the tent stand easier. When the user unfolds the first support rod 301 and the second support rod 302 to the same straight line position, the self-locking component 40 automatically locks and achieves locking without the need for additional complicated operations. This can save time and energy for users, whether they are setting up a tent quickly for camping in the wild or setting up a tent in some temporary activity venues.

[0025] In addition, in the tent support structure, the self-locking component 40 is arranged on the motion path where the first support rod 301 and the second support rod 302 are movably hinged. When the first support rod 301 is rotated to be on the same straight line L1 as the second support rod 302, this specific position becomes the key condition for triggering the self-locking function. During the rotation process, the relative positions of the components change continuously until a linear arrangement state is reached. The position information at this time is like an "instruction" that notifies the self-locking component to start working.

[0026] The self-locking assembly 40 includes a locking portion 401 located on the first support rod 301 or the second support rod 302. When the two support rods are in the same straight line position, the locking portion 401 interacts with the rod portion of the other support rod. This interaction can be achieved through a mechanical structure, for example: Buckle structure: The locking part 401 is an elastic buckle. When the two support rods are in a straight line, the buckle automatically snaps into the corresponding slot on the other support rod under the action of elastic force, thereby achieving locking. The shape and size of the slot are closely matched with the buckle, ensuring that the two support rods will not easily fall apart in the locked state; Friction structure: The locking part 401 may also be a part with a rough surface or a friction material. When the two support poles reach a straight position, the locking part 401 is in close contact with the rod of the other support pole, and the relative movement of the two support poles is prevented by friction. The magnitude of this friction force is sufficient to overcome the external force that the tent may be subjected to during normal use, such as shaking caused by breeze, slight collision, etc.

[0027] Once the self-locking function is activated and locked, the tent support forms a linear support structure. From a mechanical point of view, the entire support structure is in a new equilibrium state at this time. The external force applied to the tent (such as gravity, wind force, etc.) is transmitted to the support rod 30 through the pan head 10 and the connecting rod 20. Since the two support rods are locked in a linear state, they can cooperate to transmit these external forces to the ground in a linear direction to form a stable support.

[0028] In addition, it is necessary to specially point out that: In the technical solution provided in the present application, the locking portion 401 is self-locking with the rod portion of another supporting rod opposite thereto, which is different from the self-locking of the hinge portion itself in the traditional technology (such as the prior art CN218479638U).

[0029] On the one hand, since the structure of the hinge is relatively complex, its main function is to achieve relative rotation between the support rods rather than to withstand large axial forces. Self-locking at the hinge will cause excessive concentration of force in this local area, which may easily exceed the limit that the hinge can withstand and cause damage to the hinge, such as deformation of the connecting shaft, increased wear at the joints, etc., thereby affecting the overall stability and service life of the tent stand.

[0030] The structure of the rod is relatively simple and regular, and its shape and size are more conducive to achieving stable self-locking than the hinged part. Self-locking on the rod can utilize geometric characteristics such as the cylindrical shape of the rod (usually) to design a more reliable locking structure, such as through the matching of the locking groove and the rod, the combination of the elastic lock key and the locking hole, etc., to achieve a firm self-locking. This self-locking method based on the rod can largely avoid the self-locking failure that may occur due to the complex structure. For example, in a complex outdoor environment (including dust, rain, vibration and other factors), the linear support state of the first support rod 301 and the second support rod 302 can still be maintained.

[0031] In addition, when the locking portion 401 is self-locked with the rod portion of another support rod, the linear support structure formed by the two support rods is tighter and more stable. This linear structure is similar to a reinforced pillar, which can effectively resist deformation such as bending and twisting that may occur during the use of the tent. If self-locking is performed at the hinge part, since the hinge part itself has a certain degree of freedom of movement, it may produce a slight rotation or displacement when subjected to external force, thereby affecting the rigidity and stability of the entire linear support structure, which is not conducive to the tent bracket providing stable support for the tent.

[0032] Further, refer to Figure 4 , Figure 5 and Figure 6 As shown, the connecting rod 20 includes a first connecting rod 201 and a second connecting rod 202 which are hinged to each other, and the hinge opening direction of the two is the same as the hinge opening direction of the first support rod 301 and the second support rod 302, and is opposite to the hinge opening direction of the second support rod 302 and the second connecting rod 202; The first connecting rod 201 is movably connected to the pan head 10; The second connecting rod 202 is movably hinged to the second supporting rod 302; When the tent support structure is extended from the folded state to the unfolded state, the first support rod 301 is moved along the first direction S1 to drive the first connecting rod 201 and the second connecting rod 202 to move and rotate in the second direction S2 through the second support rod 302, so that the first connecting rod 201 and the second connecting rod 202 tend to be linearly level, such as Figure 7 As shown; The second direction S2 is opposite to the first direction S1.

[0033] This structural design allows the tent support to be extended from a folded state to an unfolded state by moving the first support rod 301 along a specific direction (first direction S1), thereby driving multiple components of the entire tent support (including the first connecting rod 201 and the second connecting rod 202) to move and rotate and extend in a preset direction (second direction S2). The user only needs to perform a relatively simple operation to unfold the tent support. The operation process is intuitive and convenient, and no complicated steps are required to adjust the positions of each component separately.

[0034] During the deployment process, the first connecting rod 201 and the second connecting rod 202 tend to be linearly flat. Figure 7 As shown, this linear structure can provide better mechanical support performance. When the tent is fully unfolded, the linear and flat connecting rods can more effectively share the weight of the tent and external forces (such as wind force). Compared with the non-linear connecting rod structure, the linear structure can reduce stress concentration and make the force transmission in the bracket structure more uniform, thereby enhancing the stability of the entire tent bracket.

[0035] In addition, when the first support rod 301 is moved along the first direction S1, since the second direction S2 is opposite thereto, the reaction force generated can be reasonably guided to other components of the tent support. This reaction force prompts the first connecting rod 201 and the second connecting rod 202 to move and rotate and extend along the second direction S2. That is, during the unfolding process, the force applied by the user is converted into the power for unfolding the tent support through this opposite direction setting, so that the force can be effectively transmitted and utilized inside the structure instead of offsetting each other.

[0036] Continue to refer to Figure 4 , Figure 5 and Figure 6 As shown, the hinged opening directions of the first support rod 301 and the second support rod 302, and the hinged opening directions of the first connecting rod 201 and the second connecting rod 202 are respectively facing upwards; The hinged opening direction of the second support rod 302 and the second connecting rod 202 is downward; When the tent support structure is extended from the folded state to the unfolded state, the first support rod 301 is moved downward in the ground support direction to drive the first connecting rod 201 and the second connecting rod 202 to move upward together and rotate and extend through the second support rod 302 .

[0037] During the deployment process, when the first support rod 301 is lifted downward in the ground support direction, gravity is used. Since the second direction S2 is upward, which is opposite to the direction of gravity, gravity can help each component to be better stretched into place during the upward deployment process. For example, when the first connecting rod 201 and the second connecting rod 202 move upward and rotate to stretch, gravity will make them naturally tend to the appropriate position during the stretching process, reducing additional adjustment work.

[0038] In short, the technical solution has the technical effect of natural extension assistance. When the tent support is extended from the folded state to the unfolded state, the first support rod 301 is pushed downward, so that the first connecting rod 201 and the second connecting rod 202 move upward and rotate and extend. This movement mode utilizes the effect of gravity. When the components are extended upward, gravity can be used as an auxiliary force to help the components adjust their positions naturally during the extension process. For example, in the process of the connecting rods rotating and extending upward, gravity will make them more easily tend to the final linear flat state, reducing additional manual adjustment operations and making the extension process smoother.

[0039] In addition, the downward movement is more in line with the principles of ergonomics. In actual operation, it is easier for users to exert force on the downward movement, and this movement is relatively natural and comfortable, without the need to bend over or twist the body excessively. This operation method that conforms to human body habits can reduce the user's fatigue during the tent setting process and improve the convenience and efficiency of operation.

[0040] Furthermore, the locking portion 401 may be located at the end of the first support rod 301 or the second support rod 302, referring to Figures 1 to 6 As shown, specifically in this embodiment, the locking portion 401 is located at the end of the first support rod 301, and the hinge portion 50 between the first support rod 301 and the second support rod 302 is located on the inner side of the end; When the tent support structure is in the folded state, the locking portion 401 is located at the bottommost position to prevent the hinge portion 50 from contacting the ground when the tent support structure is extended from the folded state to the unfolded state.

[0041] On the one hand, it can protect the hinged portion 50 and extend its service life, and on the other hand, it can ensure that the unfolding process proceeds smoothly.

[0042] Specifically, when the tent support is in a folded state, the locking portion 401 is located at the bottom, which effectively prevents the hinge 50 from contacting the ground. In the process of folding and unfolding the tent, and when the tent is placed in different ground environments (such as sand, stone, grass, etc.), the ground may cause wear to the contacting parts. Through this design, the hinge 50, which is easily damaged, is raised so that it does not directly contact the ground, which greatly reduces the wear of the hinge 50 caused by friction, thereby extending the service life of the hinge 50. It can be imagined that if the hinge 50 contacts the ground, especially on some rough or sharp ground, it may cause the hinge to deform and damage, affecting the normal use of the tent support. The design of the locking portion 401 being located at the bottom reduces the risk of such damage, ensures the integrity of the tent support structure, and improves the reliability of the tent support in various environments.

[0043] In addition, since the locking portion 401 is at the bottom in the folded state, the hinge portion 50 is prevented from contacting the ground, and when the tent frame is extended from the folded state to the unfolded state, the hinge portion 50 will not be stuck or blocked by the ground. This ensures that the tent frame can be smoothly unfolded as designed, reduces the problem of unsmooth unfolding or the need for additional adjustments due to obstruction of components, and improves the efficiency of tent erection.

[0044] Further, refer to Figure 2 and Figure 8 As shown, the locking portion 401 includes a locking groove 4011 and a locking element 4012 at least partially located in the locking groove 4011. The opening direction of the notch 4011a of the locking groove 4011 is opposite to the rod portion of another support rod, so as to be suitable for receiving the rod portion and locking with the rod portion through the locking element 4012 when the first support rod 301 and the second support rod 302 are self-locking.

[0045] As described above, in this embodiment, the locking portion 401 is located on the first support rod 301, so in this embodiment, the opening direction of the slot 4011a is opposite to the rod portion 3021 of the second support rod 302, and receives the rod portion 3021 and locks with the rod portion 3021 through the locking element 4012 when the first support rod 301 and the second support rod 302 are self-locked.

[0046] The locking groove 4011 provides a "storage space" for the rod 3021, so that when the first support rod 301 and the second support rod 302 reach a linear position, the rod 3021 can accurately enter the locking groove 4011, and for the user, it has an intuitive use experience. On the one hand, the design of the locking groove 4011 with a clear opening direction and a relatively simple locking element 4012 makes the tent bracket easier to operate during the assembly process. On the other hand, when setting up the tent, the self-locking process can be clearly seen and understood. When the first support rod 301 and the second support rod 302 are close to the linear position, the coordination between the rod and the locking groove 4011 is clear at a glance, and the user can intuitively judge whether the tent bracket is correctly self-locked, thereby improving the convenience of use and user experience.

[0047] Continue to refer to Figure 8 As shown, the locking element 4012 is arranged on the groove wall 4011b opposite to the locking groove 4011, including a locking hole 4012a arranged oppositely and an unlocking key 4012b located outside the locking hole 4012a, and the rod portion of the other support rod, that is, the rod portion 3021 of the second support rod 302 is provided with an elastic locking key 402 adapted to the locking hole 4012a; in this embodiment, the elastic locking key 402 is a "U"-shaped leaf spring.

[0048] When the first support rod 301 and the second support rod 302 are self-locked, the elastic lock key 402 is locked into the locking hole 4012a to complete the locking, and the unlocking key 4012b is operated to deform the elastic lock key 402 and disengage from the locking hole 4012a to complete the unlocking.

[0049] In addition, it is necessary to specially point out that: When the first support rod 301 and the second support rod 302 are self-locked, the elastic locking key 402 is locked into the locking hole 4012a to complete the locking, and the groove wall 4011b wraps one end of the rod 3021. When the tent is subjected to lateral wind force, the tent frame will bear a large lateral force. The wrapped structure can prevent the rod from shaking or twisting in the groove, thereby ensuring the stability of the connection between the two support rods; at the same time, the hinged end 3022 of the second support rod 302 is also transferred into the locking groove 4011 and is also wrapped by the groove wall 4011b, so that the locked connection between the second support rod 302 and the first support rod 301 forms a tight whole. From a spatial point of view, the two support rods are tightly fitted at the connection part.

[0050] In this way, the self-locking of the first support rod 301 and the second support rod 302 is not only the locking of the elastic lock key 402 and the locking hole 4012a, but also includes the wrapping of the rod portion 3021 and the hinged end 3022 by the groove wall 4011b. This connection method constrains the two support rods in multiple directions such as axial, radial and around the hinge point, so that the connection between them is no longer a simple point connection or a one-way connection, but forms an all-round tight connection structure. The relative position and angle between them can remain relatively stable when subjected to lateral wind force, and can effectively resist deformation caused by lateral wind force.

[0051] The second aspect: About Pantou 10.

[0052] Continue to refer to Figure 5 and Figure 6 As shown, the pan head 10 includes an upper pivot seat 101 and a lower pivot seat 102, and a guide rod 103 located between the upper pivot seat 101 and the lower pivot seat 102; One end of the connecting rod 20 is hinged to the upper pivot seat 101, and is hinged to the lower pivot seat 102 by an inclined rod 60; When the tent support structure is extended from the folded state to the unfolded state, the first support rod 301 is moved along the first direction S1 to drive the first connecting rod 201 and the second connecting rod 202 to rotate and extend in the second direction S2 via the second support rod 302, and then drive the upper pivot seat 101 and the lower pivot seat 102 to move relative to each other along the guide rod 103 to get closer.

[0053] In this way, the unfolding process of the tent support is a linkage process. By stirring the first support rod 301, the connecting rod 20, the upper pivot seat 101 and the lower pivot seat 102 can be driven to move in sequence. This linkage mechanism makes the tent unfolding operation easier. The user only needs to perform a simple stirring action to drive the entire tent support to unfold step by step. The relative movement of the upper pivot seat 101 and the lower pivot seat 102 along the guide rod 103 is part of this linkage process, which makes the unfolding of the tent support more orderly and efficient.

[0054] In addition, the unfolding process is relatively intuitive for the user. When unfolding the tent, the user can clearly see the movement direction and status of the upper pivot seat 101 and the lower pivot seat 102, and can easily determine whether the tent frame is unfolded correctly. This intuitive operation method improves the user experience, especially for non-professionals, it is easier to master the method of setting up the tent.

[0055] Further, the upper pivot seat 101 remains fixed relative to the guide rod 103; The lower pivot seat 102 is slidably connected with the guide rod 103 and is provided with a sliding locking sleeve 104 suitable for locking with the guide rod 103; When the tent support structure is extended from the folded state to the unfolded state, the first support rod 301 is moved along the first direction S1 to drive the first connecting rod 201 and the second connecting rod 202 to rotate and extend in the second direction S2 via the second support rod 302, and further drive the lower pivot seat 102 to move toward the upper pivot seat 101 along the guide rod 103.

[0056] Specifically, in Figure 6 and Figure 7 In the illustrated embodiment, when the tent support structure is extended from a folded state to an unfolded state, the first support rod 301 is pushed downward in the ground support direction to drive the first connecting rod 201 and the second connecting rod 202 to move upward together and rotate and extend through the second support rod 302, thereby driving the lower pivot seat 102 to move upward along the guide rod 103 and move toward the upper pivot seat 101.

[0057] Further, when the first support rod 301 rotates to be on the same straight line as the second support rod 302, the lower pivot seat 102 moves along the guide rod 103 toward the upper pivot seat 101 and is locked by the sliding locking sleeve 104 and the guide rod 103. Figure 7 shown.

[0058] When the first support rod 301 and the second support rod 302 are in a straight line and the lower pivot seat 102 and the guide rod 103 are locked, the various parts of the tent frame reach a coordinated stable state. At this time, the linearly arranged support rods and the locked pan heads together form a stable support structure. In this state, the forces (such as gravity, wind force, etc.) borne by the tent can be evenly dispersed to the ground through the stable connection between the various components, avoiding structural deformation or damage caused by excessive local force, and greatly enhancing the overall stability of the tent.

[0059] In addition, the locking mechanism effectively prevents the lower pivot seat 102 from accidentally sliding during the use of the tent. In an outdoor environment, the tent may be affected by various dynamic external forces, such as gusts of wind, activities of people in the tent, etc., and the locking state at this time can ensure the structural stability of the pan head part, avoid the shaking of the tent top or the change of the relative position between the poles caused by the sliding of the lower pivot seat 102, and maintain the integrity and stability of the tent support structure.

[0060] The third aspect: regarding the connecting piece 70.

[0061] Continue to refer to Figures 1 to 3 As shown, a connecting member 70 is further provided between the first support rod 301 and the connecting rod 20; The first support rod 301, the second support rod 302, the connecting rod 20, and the connecting member 70 together form a variable area; When the tent support structure stretches from the folded state to the unfolded state, the variable area changes from an unstable quadrilateral shape to a stable triangular shape. During the shape change process, the connecting member 70 is allowed to deform.

[0062] When the connecting rod 20 includes the first connecting rod 201 and the second connecting rod 202, the variable area is formed by the first supporting rod 301, the second supporting rod 302, the second connecting rod 202, and the connecting member 70. Figures 4 to 7 shown.

[0063] During the unfolding of the tent support, the variable area changes from an unstable quadrilateral shape to a stable triangular shape, which is a key structural optimization process. The triangle is a stable geometric shape with unique advantages in mechanical structures. When the variable area forms a triangle, the stability of its structure is greatly enhanced. Compared with the characteristic of the quadrilateral structure that is prone to deformation, the triangular structure can better resist external forces, so that the tent support can maintain a stable shape when bearing the weight of the tent and the external environmental forces (such as wind, vibration, etc.), reducing the possibility of shaking and deformation.

[0064] In addition, the connector 70 is allowed to deform during the shape change process, and this deformation characteristic cooperates with the change of the structural shape to help achieve a smoother transition. In the process of changing from a quadrilateral to a triangle, the connector 70 can be adaptively adjusted according to the movement of other components and the transmission of force, making the change of the entire structure more natural and stable.

[0065] In one embodiment, the connecting member 70 is composed of at least two rigid components hinged to each other, and the two ends of the connecting member 70 are respectively hinged to the first support rod 301 and the connecting rod 20; During the transformation from a quadrilateral to a triangle, the connector 70 is adapted to change the angle between the rigid components to accommodate the change in the structural shape.

[0066] Specifically, refer to Figures 1 to 7 As shown, the connecting member 70 is composed of three rigid components 701, 702, and 703 that are hinged to each other. In this way, the structures at both ends of the connecting member 70 can be designed to be the same, and there is no need to distinguish between the upper and lower ends, which is convenient for later assembly.

[0067] Of course, the connecting member 70 can also be composed of two rigid components 701 and 702 that are hinged to each other. Fig.10 shown.

[0068] During the tent deployment process, as the relative positions of the first support rod 301, the second support rod 302 and the connecting rod 20 change, the connecting member 70 can always maintain effective connection with the various components by adjusting its own angle, ensuring the smooth progress of the structural change process and not hindering the deployment of the tent support due to the limitations of its own structure.

[0069] After the shape transformation is completed, the connecting member 70 can still provide stable support for the tent frame, so that the tent frame can better resist external forces in the triangular shape, such as wind force, snow pressure or gravity of internal items, thereby enhancing the stability of the entire tent frame.

[0070] Reference Fig. 9 and Fig.10 As shown, when the tent support structure is in a fully unfolded state, the multiple rigid components of the connecting member 70 are straightened and aligned to rigidly support the connecting rod 20 on the first supporting rod 301 .

[0071] Thus, when the rigid components of the connector 70 are straightened and collinear to form one side of a triangle, the entire tent support structure forms a complete triangular frame. Based on the triangular shape, the rigid support of the connector 70 further enhances the structural stability.

[0072] In addition, in the fully expanded state, the rigid components are straightened and aligned, and the connecting rod 20 is rigidly supported on the first support rod 301, forming a rigid support beam on one side of the triangle. This rigid support can withstand greater pressure and prevent this side of the triangle from bending or deforming when subjected to external force; at the same time, it also strengthens the connection strength between adjacent sides, making the entire triangular structure tighter and more stable, greatly improving the ability of the tent stand to resist external deformation factors.

[0073] In another embodiment, referring to Figures 11 to 15 As shown, the connecting member 70 is a flexibly deformable elastic rope 704 ; when the shape of the variable area changes, the elastic rope 704 is suitable for generating tension to restrict the rotation of the first support rod 301 and the connecting rod 20 .

[0074] The tension of the elastic rope 704 can balance the forces between the various components of the tent frame. When the tent frame is disturbed by external factors (such as wind force, tilting force caused by uneven ground, etc.), the elastic rope 704 can rebalance the forces of the various components by changing its own tension. For example, when encountering lateral wind force, the elastic rope 704 can adjust the tension according to the wind direction and wind force, so that the first support rod 301 and the connecting rod 20 maintain a relatively stable position relationship, thereby enhancing the overall wind resistance stability of the tent frame.

[0075] In addition, the tension of the elastic rope 704 provides a guiding force for the unfolding of the tent stand. During the unfolding process, when the user moves the first support rod 301, the elastic rope 704 will generate corresponding tension according to the movement of the components. This tension can guide the first support rod 301 and the connecting rod 20 to rotate in a predetermined direction and angle. This guiding effect makes the unfolding of the tent stand smoother and reduces the unfolding difficulty or jamming caused by the uncoordinated movement of the components.

[0076] Furthermore, when the tent support structure is in a fully unfolded state, the elastic rope 704 is in a stretched state, so as to generate a downward pulling force on the connecting rod 20 along the axial direction of the elastic rope 704 .

[0077] In this way, the downward pulling force exerts an additional "fixing force" on the connecting rod 20, which can effectively prevent the connecting rod 20 from lifting or shaking upward when subjected to external interference (such as wind force, slight collision, etc.), thereby enhancing the stability of the entire tent support structure. In outdoor environments, wind force is one of the main challenges faced by tents. When the wind blows through the bottom of the tent from below or blows toward the tent from the side, the tent tends to lift up. At this time, the downward pulling force generated by the elastic rope 704 on the connecting rod 20 can effectively resist this upward force. It is like an "anchor", pulling the connecting rod 20 and the tent part connected thereto tightly to the ground, so that the tent can be better kept in place, reducing the risk of the tent being blown away or damaged by the wind.

[0078] Further, when the first support rod 301 rotates to be on the same straight line as the second support rod 302 , the variable region completes the change from the unstable quadrilateral shape to the stable triangle shape.

[0079] The deployment of a tent is a systematic process, and each component must cooperate with each other to form a stable support. The stability of the variable area will drive the coordinated stability of the entire tent frame. From the pan head to the support rod, and then to the connecting rod, the connection between the various components is tighter and more effective. When this variable area is stable, it can better transfer force to other components, making the entire tent frame work like an organic whole, jointly bearing the weight of the tent and external forces, thereby significantly enhancing the overall support stability of the tent after deployment.

[0080] In addition, the present application further relates to a tent support structure, comprising: Pan head 10; The connecting rod 20 includes a first connecting rod 201 and a second connecting rod 202 which are hinged to each other, and one end of the first connecting rod 201 is movably connected to the pan head 10; The support rod 30 includes a first support rod 301 and a second support rod 302 which are hinged to each other, and one end of the second support rod 302 is hinged to the second connecting rod 202; Reference Figure 5 and Fig.12 As shown, when the tent support structure is in a fully folded state; The hinge axis center lines of the first connecting rod 201 and the second connecting rod 202 are located on the first plane P1; The hinge axis centerline of the first support rod 301 and the second support rod 302 is located on the second plane P2; The bottom point of the locking portion 401 is located on the third plane P3; Among them, the first plane P1, the second plane P2 and the third plane P3 are parallel to each other, and compared with the supporting ground, the third plane P3 is located at the bottom, the second plane P2 is higher than the third plane P3, and the first plane P1 is higher than the second plane P2.

[0081] In this way, the height difference between the first plane P1 and the second plane P2 provides a step-by-step guiding process for the extension of the connecting rod. During the force transmission process, the first connecting rod and the second connecting rod receive the force from the second plane below on a higher plane. Due to the height difference of the planes, they will first produce an upward displacement, and then start to rotate and extend as the force continues to act. In addition, the layout in which the first plane P1 is higher than the second plane P2 provides a stable starting position for the extension of the connecting rod. In addition, the layout in which the first plane P1 is higher than the second plane P2 provides convenience for the extension of the connecting rod in space. During the process of the connecting rod moving upward and rotating and extending, since they are on a higher plane, they have a certain spatial stratification with the support rod located on the second plane, reducing the possibility of mutual interference during the movement. For example, when rotating and extending, the connecting rod will not collide with the support rod because they are at the same height. They can move freely within their respective spatial layers, thereby improving the smoothness of the entire tent support deployment process.

[0082] The third plane P3 is located at the bottom, which is determined by the locking portion 401 being located at the bottom. When the tent support structure is in a folded state, the hinge portion 50 can be prevented from contacting the ground when the tent support structure extends from the folded state to the unfolded state.
