Description

Technical Field

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

[0002] When products such as tents or awnings are unfolded or folded, the leg rods will also be unfolded or folded accordingly. The leg rods generally consist of multiple hinged support rod units. During the unfolding and folding process, relative swinging will occur between adjacent support rod units. Therefore, the stability of the connection after the adjacent support rod units are unfolded is crucial.

[0003] Through understanding of related technologies, the unfolding operations of some tent or awning products are cumbersome, and there are also problems of insufficient stability and support strength. Summary of the Invention

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

[0005] In order to achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] A tent support structure includes:

[0007] A socket head;

[0008] A connecting rod, one end of which is movably connected to the socket head;

[0009] A support rod, which includes a first support rod and a second support rod that are hinged to each other, and one end of the second support rod is hinged to the connecting rod;

[0010] It further includes:

[0011] A self-locking assembly, which includes a locking portion located on the first support rod or the second support rod;

[0012] The self-locking assembly is arranged on the movement path of the movable hinge between the first support rod and the second support rod, and is adapted to, when the first support rod rotates to be in the same straight line as the second support rod, the locking portion self-locks with the rod portion of the other support rod opposite to it, so as to lock the first support rod and the second support rod to form a linear support.

[0013] Further, the connecting rod includes a first connecting rod and a second connecting rod that are hinged to each other. The hinged opening direction of the two is the same as the hinged opening direction of the first support rod and the second support rod, and is opposite to the hinged opening direction of the second support rod and the second connecting rod;

[0014] The first connecting rod is movably connected to the socket head;

[0015] The second connecting rod is movably hinged to the second support rod;

[0016] When the tent support structure extends from the folded state to the unfolded state, the first support rod is prodded in the first direction to drive the first connecting rod and the second connecting rod to move and rotate in the second direction together through the second support rod, so that the first connecting rod and the second connecting rod tend to be linearly level;

[0017] Wherein, the second direction is opposite to the first direction.

[0018] Further, the hinged opening directions of the first support rod and the second support rod, and the hinged opening directions of the first connecting rod and the second connecting rod face upward respectively;

[0019] The hinged opening direction of the second support rod and the second connecting rod faces downward;

[0020] When the tent support structure extends from the folded state to the unfolded state, the first support rod is prodded downward in the ground support direction to drive the first connecting rod and the second connecting rod to move and rotate upward together through the second support rod.

[0021] Further, the locking portion is located at the end of the first support rod or the second support rod, and the hinged portion of the first support rod and the second support rod is located inside the end;

[0022] When the tent support structure is in the folded state, the locking portion is located at the bottommost position to prevent the hinged portion from contacting the ground when the tent support structure extends from the folded state to the unfolded state.

[0023] Further, the locking portion includes a locking groove and a locking element located in the locking groove. The opening direction of the notch of the locking groove faces the rod portion of the other support rod, so as to be adapted to receive the rod portion when the first support rod and the second support rod are self-locked and lock the rod portion through the locking element.

[0024] Further, the locking element is arranged on the opposite groove walls of the locking groove and includes a locking hole arranged oppositely and an unlocking key located outside the locking hole. An elastic locking key adapted to the locking hole is arranged on the rod portion of the other support rod;

[0025] When the first support rod and the second support rod are self-locked, the elastic locking key locks into the locking hole to complete the locking. The unlocking key is operated to deform the elastic locking key to disengage from the locking hole to complete the unlocking.

[0026] Further, the disc head includes an upper pivot seat and a lower pivot seat, and a guide rod located between the upper pivot seat and the lower pivot seat;

[0027] One end of the connecting rod is hinged to the upper pivot seat and is hinged to the lower pivot seat by an inclined rod;

[0028] When the tent bracket structure extends from the folded state to the unfolded state, the first support rod is prodded in the first direction to drive the connecting rod to rotate and extend in the second direction through the second support rod, and further drive the upper pivot seat and the lower pivot seat to move relative to each other along the guide rod to approach.

[0029] Further, the upper pivot seat is fixed relative to the guide rod;

[0030] The lower pivot seat is slidably connected relative to the guide rod and is provided with a sliding locking sleeve adapted to lock with the guide rod;

[0031] When the tent bracket structure extends from the folded state to the unfolded state, the first support rod is prodded in the first direction to drive the connecting rod to rotate and extend in the second direction through the second support rod, and further drive the lower pivot seat to move along the guide rod towards the upper pivot seat.

[0032] Further, when the first support rod rotates to be on the same straight line as the second support rod, the lower pivot seat moves along the guide rod towards the upper pivot seat and is locked with the guide rod by the sliding locking sleeve.

[0033] Further, a connecting member is further provided between the first support rod and the connecting rod;

[0034] The first support rod, the second support rod, the connecting rod, and the connecting member enclose a variable region;

[0035] When the tent bracket structure extends from the folded state to the 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.

[0036] Further, the connecting member is composed of at least two rigid members hinged to each other, and both ends of the connecting member are movably hinged to the first support rod and the connecting rod respectively;

[0037] During the shape transformation process from a quadrilateral to a triangle, the connecting member is adapted to change the angle between the rigid members to adapt to the change of the structural shape.

[0038] Further, when the tent bracket structure is in the fully unfolded state, the multiple rigid members of the connecting member are straightened and collinear to rigidly support the connecting rod on the first support rod.

[0039] Furthermore, the connecting member is a flexible and deformable elastic cord; when the variable region changes in shape, the elastic cord is adapted to generate a tensile force to restrict the rotation of the first support rod and the connecting rod.

[0040] Furthermore, when the tent support structure is in a fully deployed state, the elastic cord is in a stretched state to generate a downward tensile force on the connecting rod along the axis direction of the elastic cord.

[0041] Furthermore, when the first support rod rotates to be in the same straight line as the second support rod, the variable region completes the change from an unstable quadrilateral shape to a stable triangular shape.

[0042] The beneficial technical effects of the tent support structure provided by the present application compared with the prior art are as follows:

[0043] The self-locking function of this technical solution makes the construction process of the tent support more convenient. When the user unfolds the first support rod and the second support rod to the same straight line position, the self-locking component automatically locks, achieving locking without additional complex operations. For users, whether setting up a tent quickly during outdoor camping or setting up a tent at some temporary activity sites, it can save time and effort.

[0044] Once the self-locking function is activated and locking is completed, the tent support forms a linear support structure. From a mechanical perspective, at this time, the entire support structure is in a new equilibrium state. The forces externally applied to the tent (such as gravity, wind force, etc.) are transmitted to the support rods through the disc head and the connecting rod. Since the two support rods are locked in a linear state, they can cooperate to transmit these external forces along the linear direction to the ground to form a stable support.

[0045] Another tent support structure provided by the present application includes:

[0046] A connecting rod;

[0047] A support rod, which includes a first support rod and a second support rod that are hinged to each other, and one end of the second support rod is hinged to the connecting rod;

[0048] Characterized in that it further includes:

[0049] A connecting member, the two ends of which are respectively connected to the first support rod and the connecting rod;

[0050] The first support rod, the second support rod, the connecting rod, and the connecting member enclose a variable region;

[0051] When the tent support structure extends from the folded state to the 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.

[0052] Furthermore, the connecting member is composed of at least two rigid members hinged to each other, and both ends of the connecting member are movably hinged to the first support rod and the connecting rod respectively;

[0053] During the shape transformation process from a quadrilateral to a triangle, the connecting member is adapted to change the angle between the rigid members to adapt to the change in the structural shape.

[0054] Furthermore, when the tent support structure is in the fully unfolded state, the multiple rigid members of the connecting member are straightened and collinear to rigidly support the connecting rod on the first support rod.

[0055] Furthermore, the connecting member is a flexible and deformable elastic rope; when the shape of the variable region changes, the elastic rope is adapted to generate a tensile force to restrict the rotation of the first support rod and the connecting rod.

[0056] Furthermore, when the tent support structure is in the fully unfolded state, the elastic rope is in a stretched state to generate a downward tensile force on the connecting rod along the axis direction of the elastic rope.

[0057] Furthermore, when the first support rod rotates to be on the same straight line as the second support rod, the variable region completes the change from an unstable quadrilateral shape to a stable triangular shape.

[0058] The beneficial technical effects of the tent support structure provided by this application compared with the prior art are as follows:

[0059] During the unfolding process of the tent support, the variable region changes from an unstable quadrilateral shape to a stable triangular shape. A triangle is a stable geometric shape with unique advantages in mechanical structures. When the variable region forms a triangle, the stability of its structure is greatly enhanced. Compared with the characteristic that a quadrilateral structure is prone to deformation, a triangular structure can better resist external forces, enabling the tent support to maintain a stable shape when bearing the weight of the tent and external environmental forces (such as wind force, vibration, etc.), and reducing the possibility of shaking and deformation.

[0060] In addition, the connecting member is allowed to deform during the shape change process, and this deformation characteristic cooperates with the transformation of the structural shape, which helps to achieve a smoother transition. During the change from a quadrilateral to a triangle, the connecting member can make adaptive adjustments according to the movement of other components and the transmission of forces, making the change of the entire structure more natural and stable.

[0061] In addition, the present invention also relates to a tent based on the tent support structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0078] Next, the technical solution of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0079] This application involves three aspects of technical content, which will be elaborated in detail one by one below.

[0080] First aspect: Regarding the self-locking component 40.

[0081] Referring to Figure 1 and Figure 2 shown, a tent support structure includes:

[0082] a socket head 10;

[0083] a connecting rod 20, one end of which is movably connected to the socket head 10;

[0084] a support rod 30, which includes a first support rod 301 and a second support rod 302 that are hinged to each other, and one end of the second support rod 302 is hinged to the connecting rod 20;

[0085] a self-locking component 40, which includes a locking portion 401 located on the first support rod 301 or the second support rod 302;

[0086] The self-locking assembly 40 is arranged on the movement path where the first support rod 301 and the second support rod 302 are movably hinged. When the first support rod 301 rotates to be on the same straight line L1 as the second support rod 302, the locking portion 401 self-locks with the rod portion of the other support rod 30 opposite to it, so as to lock the first support rod 301 and the second support rod 302 to form a linear support.

[0087] Specifically, in the embodiment as Figures 1 to 3 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 Figure 3 shown, the locking portion 401 self-locks with the rod portion 3021 of 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.

[0088] The self-locking function of this technical solution makes the erection process of the tent bracket more convenient. When the user unfolds the first support rod 301 and the second support rod 302 to the same straight line position, the self-locking assembly 40 automatically locks, achieving locking without additional complex operations. For users, whether it is quickly erecting a tent during outdoor camping or erecting a tent at some temporary activity sites, it can save time and effort.

[0089] In addition, in the tent bracket structure, the self-locking assembly 40 is arranged on the movement path where the first support rod 301 and the second support rod 302 are movably hinged. When the first support rod 301 rotates 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 they reach the linear arrangement state. At this time, the position information is like an "instruction" to notify the self-locking assembly to start working.

[0090] 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 opposite support rod. This interaction can be achieved through a mechanical structure. For example:

[0091] Snap structure: The locking portion 401 is an elastic snap. When the two support rods are in a straight line, the snap automatically snaps into the corresponding slot on the rod portion of the other support rod under the action of elastic force, thus achieving locking. The shape and size of the slot are closely matched with the snap to ensure that the two support rods will not easily separate in the locked state;

[0092] Frictional structure: The locking part 401 can also be a component with a rough surface or with friction material. When the two support rods reach the straight position, the locking part 401 is in close contact with the rod part of the other support rod, and relies on friction to prevent the relative movement of the two support rods. The magnitude of this frictional force is sufficient to overcome the external forces that the tent may be subjected to during normal use, such as the sway caused by a gentle breeze, a slight collision, etc.

[0093] Once the self-locking function is activated and the locking is completed, the tent support forms a linear support structure. From a mechanical perspective, at this time the entire support structure is in a new equilibrium state. The forces applied externally to the tent (such as gravity, wind force, etc.) are transmitted to the support rods 30 through the disc 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 along the linear direction to the ground to form a stable support.

[0094] In addition, it should be specifically noted that:

[0095] In the technical solution provided in this application, the locking part 401 self-locks with the rod part of the other support rod opposite to it, which is different from the self-locking at the hinge part itself in the traditional technology (such as the prior art CN218479638U).

[0096] On the one hand, due to the relatively complex structure of the hinge part, its main function is to achieve the relative rotation between the support rods, rather than to bear a large axial force. Self-locking at the hinge part will cause the force to be overly concentrated in this local area, easily exceeding the limit that the hinge part can bear, resulting in damage to the hinge part, such as the deformation of the connecting shaft, the aggravation of wear at the joint, etc., thus affecting the overall stability and service life of the tent support.

[0097] The structure of the rod part is relatively simple and regular. Compared with the hinge part, its shape and size are more conducive to achieving stable self-locking. Self-locking at the rod part can utilize the geometric characteristics of the rod part, such as its cylindrical shape (usually), etc., to design a more reliable locking structure, such as through the cooperation of the locking groove and the rod part, the combination of the elastic locking key and the locking hole, etc., to achieve firm self-locking. This self-locking method based on the rod part can largely avoid the self-locking failure situation that may occur due to complex structure. For example, in a complex outdoor environment (including the influence of factors such as sand and dust, rain, vibration, etc.), the linear support state of the first support rod 301 and the second support rod 302 can still be maintained.

[0098] 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 more compact and stable. This linear structure is similar to a strengthened pillar and can effectively resist deformations such as bending and twisting that may occur during the use of the tent. If self-locking is performed at the hinge portion, since the hinge portion itself has a certain degree of freedom of movement, it may produce slight rotation or displacement when subjected to external forces, thereby affecting the rigidity and stability of the entire linear support structure and being unfavorable for the tent bracket to provide stable support for the tent.

[0099] Further, referring to Figure 4 , Figure 5 and Figure 6 shown, the connecting rod 20 includes a first connecting rod 201 and a second connecting rod 202 that are hinged to each other. The hinged opening directions of the two are the same as the hinged opening direction of the first support rod 301 and the second support rod 302, and are opposite to the hinged opening direction of the second support rod 302 and the second connecting rod 202;

[0100] The first connecting rod 201 is movably connected to the disc head 10;

[0101] The second connecting rod 202 is movably hinged to the second support rod 302;

[0102] When the tent bracket structure extends from the folded state to the unfolded state, the first support rod 301 is prodded in the first direction S1 to drive the first connecting rod 201 and the second connecting rod 202 to move and rotate and extend together 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, as shown in Figure 7 shown;

[0103] wherein, the second direction S2 is opposite to the first direction S1.

[0104] This structural design enables the tent bracket, when extending from the folded state to the unfolded state, by prodding the first support rod 301 in a specific direction (the first direction S1), to drive multiple components of the entire tent bracket (including the first connecting rod 201 and the second connecting rod 202) to move and rotate and extend in a preset direction (the second direction S2). The user only needs to perform a relatively simple operation action to realize the unfolding of the tent bracket. The operation process is intuitive and convenient, and there is no need for complex steps to separately adjust the positions of each component.

[0105] During the unfolding process, the first connecting rod 201 and the second connecting rod 202 tend to be linearly level. Referring to Figure 7As shown, this linear structure can provide better mechanical support performance. When the tent is fully unfolded, the linearly level connecting rods can more effectively share the weight of the tent and the forces applied externally (such as wind force). Compared with the non-linear connecting rod structure, the linear structure can reduce the stress concentration, making the force transmission in the bracket structure more uniform, thus enhancing the stability of the entire tent bracket.

[0106] In addition, when the first support rod 301 is prodded along the first direction S1, due to the second direction S2 being opposite to it, the resulting reaction force can be reasonably guided to other components of the tent bracket. This reaction force causes the first connecting rod 201 and the second connecting rod 202 to move and rotate along the second direction S2 and extend. That is, during the unfolding process, the force applied by the user is converted into the power to unfold the tent bracket through this opposite-direction setting, enabling the force to be effectively transmitted and utilized within the structure instead of being offset against each other.

[0107] Continue to refer to Figure 4 , Figure 5 and Figure 6 As shown, the hinge opening directions of the first support rod 301 and the second support rod 302, and the hinge opening directions of the first connecting rod 201 and the second connecting rod 202 are respectively upward;

[0108] The hinge opening direction of the second support rod 302 and the second connecting rod 202 is downward;

[0109] When the tent bracket structure extends from the folded state to the unfolded state, prod the first support rod 301 downward in the ground support direction to drive the first connecting rod 201 and the second connecting rod 202 to move and rotate upward together through the second support rod 302.

[0110] During the unfolding process, when the first support rod 301 is prodded downward in the ground support direction, the effect of gravity is utilized. Since the second direction S2 is upward, opposite to the direction of gravity, during the upward unfolding process, gravity can help each component extend to the appropriate position better. For example, when the first connecting rod 201 and the second connecting rod 202 move and rotate upward and extend, gravity will cause them to naturally tend to the appropriate position during the extension process, reducing the need for extra adjustment work.

[0111] In short, this technical solution has the technical effect of natural stretching assistance. When the tent support is stretched from the folded state to the unfolded state, the first support rod 301 is lifted downward, causing the first connecting rod 201 and the second connecting rod 202 to move upward and rotate and stretch. This movement method utilizes the effect of gravity. When the components are unfolded upward, gravity can act as an auxiliary force to help the components naturally adjust their positions during the stretching process. For example, during the upward rotation and stretching of the connecting rods, gravity will make it easier for them to tend to the final linear flat state, reducing the need for additional manual adjustment operations and making the unfolding process smoother.

[0112] In addition, the action of lifting downward conforms more to the principles of ergonomics. In actual operation, it is easier for the user to exert force on the downward action, and this action is relatively natural and comfortable, without the need to bend over or twist the body excessively. This operation method that conforms to human habits can reduce the fatigue of the user during the process of setting up the tent and improve the convenience and efficiency of the operation.

[0113] Furthermore, the locking portion 401 can be located at the end of the first support rod 301 or the second support rod 302. Refer 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 of the first support rod 301 and the second support rod 302 is located inside the end;

[0114] 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 stretched from the folded state to the unfolded state.

[0115] On the one hand, it can achieve the technical effect of protecting the hinge portion 50 and extending its service life. On the other hand, it can ensure the smooth progress of the unfolding process.

[0116] Specifically, when the tent support is in the folded state, the locking portion 401 is located at the bottommost position, effectively preventing the hinge portion 50 from contacting the ground. During the process of folding and unfolding the tent, as well as when the tent is placed on different ground environments (such as sandy ground, rocky ground, grassland, etc.), the ground may cause wear to the contacting components. Through this design, the easily damaged hinge portion 50 is lifted, making it not directly contact the ground, greatly reducing the wear of the hinge portion 50 caused by friction, thereby extending the service life of the hinge portion 50. It can be imagined that if the hinge portion 50 contacts the ground, especially on some rough or sharp object-containing ground, it may cause the hinge portion to deform or be damaged, affecting the normal use of the tent support. And the design of the locking portion 401 located at the bottommost position reduces this risk of damage, ensures the integrity of the tent support structure, and improves the reliability of the tent support in various environments.

[0117] In addition, since the locking portion 401 is at the bottommost end in the folded state, it prevents the hinge portion 50 from contacting the ground. When the tent bracket extends from the folded state to the unfolded state, the hinge portion 50 will not be stuck or obstructed by the ground. This can ensure that the tent bracket can be smoothly unfolded in the designed manner, reduce the problems of unsmooth unfolding or the need for additional adjustment caused by component obstruction, and improve the efficiency of tent setup.

[0118] Further, referring 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 faces the rod portion of another support rod, so as to receive the rod portion and lock it with the rod portion through the locking element 4012 when the first support rod 301 and the second support rod 302 are self-locked.

[0119] As described above, in this embodiment, the locking portion 401 is located on the first support rod 301. Therefore, in this embodiment, the opening direction of the notch 4011a faces the rod portion 3021 of the second support rod 302, and receives the rod portion 3021 and locks it 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.

[0120] The locking groove 4011 provides a "receiving space" for the rod portion 3021, so that when the first support rod 301 and the second support rod 302 reach the linear position, the rod portion 3021 can accurately enter the locking groove 4011. Moreover, 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 the 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 cooperation between the rod portion and the locking groove 4011 is obvious at a glance, and the user can intuitively judge whether the tent bracket is correctly self-locked, improving the convenience of use and the user experience.

[0121] Continuing to refer to Figure 8 As shown, the locking element 4012 is arranged on the opposite groove walls 4011b of the locking groove 4011, and includes oppositely arranged locking holes 4012a and unlocking keys 4012b located outside the locking holes 4012a. An elastic locking key 402 adapted to the locking holes 4012a is provided on the rod portion of another support rod, that is, the rod portion 3021 of the second support rod 302; in this embodiment, the elastic locking key 402 is a "U"-shaped leaf spring.

[0122] When the first support rod 301 and the second support rod 302 are self-locked, the elastic lock key 402 locks into the locking hole 4012a to complete the locking. Operating the unlocking key 4012b causes the elastic lock key 402 to deform and disengage from the locking hole 4012a to complete the unlocking.

[0123] In addition, it should be particularly noted that:

[0124] When the first support rod 301 and the second support rod 302 are self-locked, the elastic lock key 402 locks into the locking hole 4012a to complete the locking. The groove wall 4011b wraps around one end of the rod portion 3021. When the tent is subjected to lateral wind force, the tent support will bear a large lateral force. The wrapped structure can prevent the rod from shaking or twisting in the groove, 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 also turns into the locking groove 4011 and is also wrapped by the groove wall 4011b, making the locking connection between the second support rod 302 and the first support rod 301 form a tight whole. Spatially, the two support rods are closely fitted at the connection part.

[0125] 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 groove wall 4011b around the rod portion 3021 and the hinged end 3022. This connection method restricts the two support rods in multiple directions such as the axial direction, the radial direction, and the direction around the hinge point, making their connection no longer a simple point connection or one-way connection, but a full-range tight connection structure. Their relative position and angle can remain relatively stable when subjected to lateral wind force, and can effectively resist the deformation caused by lateral wind force.

[0126] Second aspect: Regarding the disc head 10.

[0127] Continue to refer to Figure 5 and Figure 6 As shown, the disc 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;

[0128] 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;

[0129] When the tent support structure extends from the folded state to the unfolded state, the first support rod 301 is prodded in 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 through the second support rod 302, and further drive the upper pivot seat 101 and the lower pivot seat 102 to move relative to each other along the guide rod 103 to approach.

[0130] In this way, the unfolding process of the tent support is a linkage process. By prodding the first support rod 301, the movement of components such as the connecting rod 20, the upper pivot seat 101, and the lower pivot seat 102 can be driven in sequence. This linkage mechanism makes the tent unfolding operation more convenient. The user only needs to perform a simple prodding action to drive the entire tent support to gradually unfold. 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.

[0131] In addition, this unfolding process is relatively intuitive for the user. When unfolding the tent, the user can clearly see the movement direction and state of the upper pivot seat 101 and the lower pivot seat 102, and can easily judge whether the tent support is correctly unfolded. This intuitive operation method improves the user experience. Especially for non-professionals, it is easier to master the tent erection method.

[0132] Furthermore, the upper pivot seat 101 remains fixed relative to the guide rod 103;

[0133] The lower pivot seat 102 is slidably connected relative to the guide rod 103 and is provided with a sliding locking sleeve 104 adapted to lock with the guide rod 103;

[0134] When the tent support structure extends from the folded state to the unfolded state, prod the first support rod 301 in 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 upward along the guide rod 103 towards the upper pivot seat 101.

[0135] Specifically, in the embodiments as shown in Figure 6 and Figure 7 , when the tent support structure extends from the folded state to the unfolded state, prod the first support rod 301 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 via the second support rod 302, and further drive the lower pivot seat 102 to move upward along the guide rod 103 and move towards the upper pivot seat 101.

[0136] Furthermore, when the first support rod 301 rotates to be in the same straight line as the second support rod 302, the lower pivot seat 102 moves upward along the guide rod 103 towards the upper pivot seat 101 and is locked with the guide rod 103 by the sliding locking sleeve 104, as shown in Figure 7 .

[0137] When the first support rod 301 and the second support rod 302 are aligned, and the lower pivot 102 is locked with the guide rod 103, the various components of the tent frame achieve a coordinated and stable state. At this point, the linearly arranged support rods and the locked pan head together form a stable support structure. In this state, forces exerted on the tent (such as gravity and wind) are evenly distributed to the ground through the stable connections between the various components, preventing structural deformation or damage caused by excessive local forces and greatly enhancing the overall stability of the tent.

[0138] Furthermore, the locking mechanism effectively prevents the lower pivot 102 from accidentally sliding during use. In outdoor environments, tents may be subject to various dynamic external forces, such as gusts of wind and the movement of people inside the tent. The locked state ensures the structural stability of the pan head, preventing the tent top from shaking or the relative position of the poles from shifting due to the sliding of the lower pivot 102, thus maintaining the integrity and stability of the tent frame structure.

[0139] The third aspect: regarding the connecting piece 70.

[0140] 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;

[0141] The first support rod 301, the second support rod 302, the connecting rod 20, and the connecting member 70 together form a variable area;

[0142] When the tent support structure stretches from the folded state to the unfolded state, the variable region changes from an unstable quadrilateral shape to a stable triangular shape. During the shape change process, the connecting member 70 is allowed to deform.

[0143] 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 support rod 301, the second support rod 302, the second connecting rod 202, and the connecting member 70. Figures 4 to 7 shown.

[0144] During the tent's deployment process, the variable area changes from an unstable quadrilateral to a stable triangular shape, a critical structural optimization process. A triangle is a stable geometric shape with unique advantages in mechanical structures. When the variable area forms a triangle, its structural stability is greatly enhanced. Compared to a quadrilateral structure, which is prone to deformation, a triangular structure is better able to resist external forces. This allows the tent to maintain its shape and reduce the possibility of shaking and deformation when subjected to the weight of the tent and external environmental forces (such as wind and vibration).

[0145] In addition, the connecting member 70 is allowed to deform during the morphological change process, and this deformation characteristic cooperates with the transformation of the structural form, which helps to achieve a smoother transition. During the change from a quadrilateral to a triangle, the connecting member 70 can adaptively adjust according to the movement and force transmission of other components, making the change of the entire structure more natural and stable.

[0146] In one embodiment, the connecting member 70 is composed of at least two rigid members 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 movably.

[0147] During the morphological transformation from a quadrilateral to a triangle, the connecting member 70 is adapted to change the angle between the rigid members to adapt to the change of the structural form.

[0148] Specifically, referring to Figures 1 to 7 as shown, the connecting member 70 is composed of three rigid members 701, 702, and 703 hinged to each other. In this way, the structures at both ends of the connecting member 70 can be designed to be the same, without the need to distinguish between the upper and lower ends, which is convenient for later assembly.

[0149] Of course, the connecting member 70 can also be composed of two rigid members 701 and 702 hinged to each other, referring to Figure 10 as shown.

[0150] During the tent unfolding 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 each component by adjusting its own angle, ensuring the smooth progress of the structural change process and not hindering the unfolding of the tent bracket due to the limitation of its own structure.

[0151] After the morphological transformation is completed, the connecting member still can provide stable support for the tent bracket, enabling the tent bracket to better resist external forces in the triangular form, such as the wind force, snow pressure, or the gravity of internal items on the tent, thereby enhancing the stability of the entire tent bracket.

[0152] Referring to Figure 9 and Figure 10 as shown, when the tent bracket structure is in the fully unfolded state, the multiple rigid members of the connecting member 70 are straightened and collinear to rigidly support the connecting rod 20 on the first support rod 301.

[0153] In this way, when the rigid members of the connecting member 70 are straightened and collinear to form a side of the triangle, the entire tent bracket structure forms a complete triangular frame. Based on the triangular form, the rigid support of the connecting member 70 further enhances the structural stability.

[0154] In addition, in the fully expanded state, the rigid components are straightened and collinear, rigidly supporting the connecting rod 20 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.

[0155] In another embodiment, referring to Figures 11 to 15 As shown, the connecting member 70 is a flexible and 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.

[0156] The tension of the elastic cord 704 balances the forces between the various components of the tent frame. When the tent frame is disturbed by external factors (such as wind or rolling forces caused by uneven ground), the elastic cord 704 can rebalance the forces acting on the various components by varying its own tension. For example, when encountering a sideways wind, the elastic cord 704 can adjust its tension based on the wind direction and force, maintaining a relatively stable position between the first support rod 301 and the connecting rod 20, thereby enhancing the overall wind resistance of the tent frame.

[0157] Furthermore, the tension of the elastic cord 704 provides a guiding force for the tent frame to unfold. During the unfolding process, when the user moves the first support rod 301, the elastic cord 704 generates a corresponding tension based on the movement of the components. This tension guides the first support rod 301 and the connecting rod 20 to rotate in the predetermined direction and angle. This guiding effect makes the tent frame unfold more smoothly, reducing the difficulty or jamming caused by uncoordinated component movement.

[0158] Furthermore, when the tent support structure is fully deployed, the elastic rope 704 is in a stretched state, so as to generate a downward pulling force on the connecting rod 20 along the axis direction of the elastic rope 704 .

[0159] Thus, this downward pulling force exerts an additional "fixing force" on the connecting rod 20, which can effectively prevent the connecting rod 20 from lifting upward or shaking when subjected to external disturbances (such as wind force, slight collision, etc.), thereby enhancing the stability of the entire tent support structure. In an outdoor environment, wind force is one of the main challenges faced by tents. When the wind blows under the bottom of the tent or blows towards the tent from the side, the tent has a tendency to lift upward. At this time, the downward pulling force generated by the elastic rope 704 on the connecting rod 20 can effectively resist this upward lifting force. It is like an "anchor", pulling the connecting rod 20 and the tent part connected thereto tightly towards the ground, enabling the tent to better maintain its position in place and reducing the risk of the tent being blown away or damaged.

[0160] Further, when the first support rod 301 rotates to be in the same straight line as the second support rod 302, the variable region completes the change from an unstable quadrilateral shape to a stable triangular shape.

[0161] The deployment of the tent is a systematic process, and each component needs to cooperate with each other to form a stable support. The stability of the variable region will drive the coordinated stability of the entire tent support. From the disc head part to the support rods and then to the connecting rods, the connections between the components are tighter and more effective. When this variable region is stable, it can better transfer the force to other components, enabling the entire tent support to work like an organic whole, jointly bearing the weight of the tent and external acting forces, thereby significantly enhancing the overall support stability after the tent is deployed.

[0162] In addition, the present application further relates to a tent support structure, comprising:

[0163] A disc head 10;

[0164] A connecting rod 20, which includes a first connecting rod 201 and a second connecting rod 202 that are hinged to each other, and one end of the first connecting rod 201 is movably connected to the disc head 10;

[0165] A support rod 30, which includes a first support rod 301 and a second support rod 302 that are hinged to each other, and one end of the second support rod 302 is hinged to the second connecting rod 202;

[0166] Referring to Figure 5 and Figure 12 As shown, when the tent support structure is in a fully folded state;

[0167] The hinge axis centerlines of the first connecting rod 201 and the second connecting rod 202 are located on the first plane P1;

[0168] The hinge axis centerlines of the first support rod 301 and the second support rod 302 are located on the second plane P2;

[0169] The lowest point of the above-mentioned locking part 401 is located on the third plane P3;

[0170] Among them, the first plane P1, the second plane P2 and the third plane P3 are parallel to each other. Compared with the supporting ground, the third plane P3 is at the lowest position, the second plane P2 is higher than the third plane P3, and the first plane P1 is higher than the second plane P2.

[0171] In this way, the height difference between the first plane P1 and the second plane P2 provides a gradual 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 lower second plane on the higher plane. Due to the height difference between the planes, they will first generate an upward displacement, and then start to rotate and extend as the force continues to act. Moreover, the layout where 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 where the first plane P1 is higher than the second plane P2 facilitates the extension of the connecting rod in space. During the upward displacement and rotational extension of the connecting rod, since they are on a higher plane, there is a certain layering in space with the support rod located on the second plane, reducing the possibility of interference with each other during movement. For example, during rotational extension, the connecting rod will not collide because it is at the same height as the support rod. They can move freely within their respective spatial levels, thus improving the smoothness of the entire tent bracket unfolding process.

[0172] The third plane P3 is at the lowest position, which is determined by the fact that the locking part 401 is at the bottommost position. When the tent bracket structure is in the folded state, it can prevent the hinge part 50 from contacting the ground when the tent bracket structure extends from the folded state to the unfolded state.

[0173] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
