Description

Technical Field

[0001] This invention belongs to the field of outdoor products and relates to a foldable tent, specifically a foldable tent with eaves poles. Background Technology

[0002] Tents are widely used in outdoor activities such as camping, providing protection from wind, rain, and insects, as well as warmth. Traditional foldable tents offer relatively little shade. To increase the shaded area when the tent is fully open, tents with eaves structures were developed. These tents have eaves poles extending from the top corners, and the area is increased by edging attached to these poles. These tents primarily use eaves poles that are pivotally or insert into the top poles of the tent frame. After the main tent is unfolded, the eaves poles can be selectively extended to increase the shaded area. However, existing tents may have issues with the strength of the eaves poles when fully extended. Summary of the Invention

[0003] To address the technical problem, this invention provides an improved collapsible tent that allows for flexible opening or folding of the eaves poles as needed, while the eaves poles exhibit good strength when opened.

[0004] A foldable tent includes a tent frame body, eaves poles, and a surrounding fabric. The tent frame body includes:

[0005] Multiple legs;

[0006] The eaves frame is connected between two adjacent legs;

[0007] When the foldable tent is unfolded, the eaves pole has an open state and a folded state; when the eaves pole is in the open state, the inner end of the eaves pole is connected to the tent frame body, the outer end of the eaves pole is offset from the leg pole by a certain distance, and the eaves pole is transverse to the leg pole so as to support the surrounding fabric; when the eaves pole is in the folded state, the surrounding fabric hangs down to the side of the tent frame body;

[0008] The collapsible tent also includes a crossbar, the two ends of which are respectively used to connect to the eaves frame and the eaves pole, so that the strength of the eaves pole is strengthened when the collapsible tent is in the open state.

[0009] In a preferred embodiment, the crossbar has a first end rotatably connected to the eaves pole and a second end for detachable connection to the eaves frame; the eaves pole has a folded state and an open state. In the folded state, the second end of the crossbar is detached from the eaves frame, and the outer end of the eaves pole is close to the leg pole; in the open state, the second end of the crossbar is connected to the eaves frame, and the outer end of the eaves pole is offset from the leg pole by a certain distance; during the process of switching the foldable tent from the unfolded state to the folded state, the second end of the crossbar is detached from the eaves frame, and the eaves pole changes from the open state to the folded state. This allows for flexible selection of opening or closing the eaves pole as needed, while avoiding damage to the tent structure during folding due to forgetting to close the eaves pole. Once unfolded, the canopy poles can be opened or closed flexibly as needed, and opening and closing are quick and convenient; in particular, when folding up the tent, if the canopy poles are forgotten to be closed, as the eaves frame is folded, the second end of the crossbar can be separated from the eaves frame under the action of external force, so that the canopy poles will not be accidentally broken or the main structure of the tent frame will not be damaged due to forgetting to close the canopy poles.

[0010] In a preferred embodiment, the inner end of the eaves pole is rotatably connected to the leg pole, and the tent further includes a support pole having a first end and a second end, the first end being rotatably and slidably connected to the leg pole in the vertical direction, and the second end being rotatably connected to the eaves pole.

[0011] More preferably, the first end of the support rod is rotatably connected to the support base, and the support base is slidably connected to the leg rod in the vertical direction.

[0012] Furthermore, an eaves locking mechanism is provided between the support base and the leg rod, which locks the support base and the leg rod when the eaves rod is in the open state.

[0013] More preferably, a fixed seat is provided between the inner end and the outer end of the eaves rod, the first end of the crossbar is rotatably connected to the fixed seat via a first pivot, and the second end of the support rod is rotatably connected to the fixed seat via a second pivot. When the eaves rod is in the folded state, the angle between the center lines of the first pivot and / or the second pivot and the horizontal plane is less than 10 degrees. When the eaves rod is in the folded state, the center lines of the first pivot and the second pivot are preferably parallel to the horizontal plane or inclined at only a small angle, so that the eaves rod and the crossbar can automatically fall and hang beside the leg rod under their own weight, thereby strengthening the leg rod.

[0014] Optionally, a fixed seat is provided between the inner end and the outer end of the eaves rod, and the fixed seat is rotatably connected to a rotating seat. One of the first end of the crossbar and the second end of the support rod is rotatably connected to the fixed seat and the other is rotatably connected to the rotating seat.

[0015] Optionally, a fixed seat is provided between the inner end and the outer end of the eaves rod, and one of the first end of the crossbar and the second end of the support rod is pivotally connected to the fixed seat while the other is rotatably connected to the fixed seat via a universal joint.

[0016] Furthermore, when the eaves pole is folded, the support pole is close to the front or back of the eaves pole, and the support pole is completely covered by the eaves pole when viewed from the front or back.

[0017] More preferably, when the eaves rod is in the folded state, the outer end of the eaves rod, the first end of the support rod, and the lower end of the leg rod are close together.

[0018] In a preferred embodiment, the eaves frame includes a link that can rotate downward when the main body of the tent frame is folded, and a slot is formed on the second end of the crossbar that can be engaged with the link.

[0019] More preferably, the slot portion has a downward-facing opening.

[0020] More preferably, the groove formed by the groove portion extends upward from the lower surface of the groove portion. Furthermore, in the cross-section of the groove portion perpendicular to the length direction of the connecting rod, the outline of the groove is generally an inverted U-shape.

[0021] Furthermore, a positioning protrusion is formed on the connecting rod, and the slot portion has a positioning groove that mates with the positioning protrusion. Even further, the positioning groove has two opposing limiting walls, the limiting walls being not parallel to the length direction of the connecting rod, and the positioning protrusion is located between these two limiting walls to prevent the slot portion from moving back and forth on the connecting rod.

[0022] In a preferred embodiment, the outer end of the eaves rod is connected to the surrounding fabric.

[0023] In one embodiment, the eaves rod is detachably inserted into the leg rod, and when the eaves rod is in the open state, the inner end of the eaves rod is inserted into the leg rod; when the eaves rod is in the folded state, the inner end of the eaves rod is detached from the leg rod.

[0024] In one embodiment, each of the eaves rods extends along the length of one of the eaves frames when in the open state.

[0025] In one embodiment, when the collapsible tent is folded, the eaves pole applies force to the crossbar, causing the crossbar to automatically detach from the eaves frame.

[0026] In a preferred embodiment, the tent frame body further includes multiple foldable top rod units. Each top rod unit includes an inner top rod and an outer top rod rotatably connected at their ends. The other end of the outer top rod is rotatably connected to the upper end of the leg pole. The other end of the inner top rod of each top rod unit is rotatably connected to a central locking mechanism. The tent frame body also includes a reinforcing mechanism connecting the eaves frame and the top rod units or the eaves frame and the central locking mechanism. This counteracts or reduces the thrust of the crossbars on the eaves frame, preventing the eaves frame from deforming inwards due to the pretension of the fabric cover.

[0027] More preferably, the reinforcing mechanism includes a reinforcing rod, one end of which is rotatably connected to the inner top rod and the other end of which is rotatably connected to the eaves frame.

[0028] More preferably, the reinforcing mechanism includes an outer reinforcing rod and an inner reinforcing rod rotatably connected at one end, the other end of the outer reinforcing rod being rotatably connected to the eaves frame, and the other end of the outer reinforcing rod being rotatably connected to the center locking mechanism.

[0029] Furthermore, the eaves frame includes at least one link assembly rotatably connected between the legs. The link assembly includes two first and second links that can be extended and brought together relative to each other. The middle portions of the first and second links are rotatably connected via a third pivot. The other end of the outer reinforcing rod is rotatably connected to a connector, which is connected to the third pivot.

[0030] Furthermore, the central locking mechanism includes a top cap and a bottom cap that can be locked or disengaged from each other. The other end of the inner top rod is rotatably connected to the top cap. Each top rod unit also includes an auxiliary top rod, one end of which is rotatably connected to the inner top rod and the other end of which is rotatably connected to the bottom cap. The reinforcing mechanism also includes an auxiliary reinforcing rod, one end of which is rotatably connected to the inner reinforcing rod and the other end of which is rotatably connected to the bottom cap.

[0031] The present invention adopts the above solution, which has the following advantages compared with the prior art:

[0032] The collapsible tent of the present invention allows for flexible selection of opening or folding of the eaves poles after unfolding, and the opening and closing are quick and convenient; in particular, after the eaves poles are opened, by setting a crossbar and connecting it between the eaves poles and the roof frame, the eaves poles have good strength after being opened.

[0071] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0072] Example 1

[0073] Reference Figures 1 to 12 As shown, the collapsible tent of this embodiment has an unfolded state and a folded state, and includes a collapsible tent frame body 2; the tent frame body 2 can be independently supported on the ground, and the tent frame body 2 is covered with a cloth cover (not shown in the figure) for sunshade, wind protection, rain protection, etc.; wherein a part of the cloth cover (e.g., the edge part) can hang down to the side of the tent frame body 2, and this part of the cover is called the drape. Figure 1 and Figures 3 to 5 As shown, the tent frame body 2 includes multiple leg poles 1 extending vertically and a top frame connected to the upper part of the leg poles 1. The tent is supported on the ground by the leg poles 1, and the fabric cover mainly covers the top frame. The tent also includes eaves poles 3 with inner and outer ends. The inner end of the eaves pole 3 is rotatably connected to the leg pole 1, specifically via a pivot. There are multiple eaves poles 3, and their number and position correspond one-to-one with the leg poles 1. That is, the inner end of each eaves pole 3 is rotatably connected to the corresponding leg pole 1. The aforementioned fabric is connected to the outer end of the eaves pole 3 and can be opened by the eaves pole 3 to serve as an eave to increase the sunshade area. It can also hang down to the side of the tent as the eaves pole 3 is folded, serving as side drapes. Each eaves pole 3 has a folded state and an open state. In the folded state, the outer end of the eaves pole 3 is close to the leg pole 1, while in the open state, it is offset from the leg pole 1 by a certain distance. In other words, the eaves pole 3 has a folded state where it is close to the leg pole 1, and an open state where it is unfolded relative to the leg pole 1. When the eaves pole 3 is unfolded, the surrounding fabric extends outward, increasing the sunshade area of ​​the tent. Furthermore, the left eaves pole 3 extends to the left when it is open, meaning that the outer end of the eaves pole 3 is located on the left side of the leg pole 1; the right eaves pole 3 extends to the right when it is open, meaning that the outer end of the eaves pole 3 is located on the right side of the leg pole 1; thus, the surrounding fabric on the left and right sides can be opened, increasing the eaves area on the left and right sides of the tent, and increasing the sunshade area on both sides. When the eaves pole 3 is folded, the surrounding fabric hangs down and is located on the side of the tent.

[0074] The roof frame includes multiple foldable eaves frames 21, which are connected to adjacent leg poles 1. The tent also includes multiple crossbars 4, the number and position of which correspond one-to-one with the eaves poles 3. Figures 7 to 12 As shown, each crossbar 4 has a first end rotatably connected to the eaves pole 3 and a second end for detachable connection to the eaves frame 21. When the eaves pole 3 is in the folded state, the second end of the crossbar 4 is detached from the eaves frame 21; when the eaves pole 3 is in the open state, the second end of the crossbar 4 is connected to the eaves frame 21. During the process of switching the tent frame body 2 from the unfolded state to the folded state, the second end of the crossbar 4 detaches from the eaves frame 21, and the eaves pole 3 changes from the open state to the folded state. The second end of the crossbar 4 and the eaves frame 21 are detachably connected and configured to automatically detach from the eaves frame 21 when subjected to force from the crossbar 3 during folding. One implementation of this configuration will be described in detail below.

[0075] It should also be noted that in this embodiment, the eaves rod 3 is directly rotatably connected to the leg rod 1 via a pivot; in other embodiments, the eaves rod 3 can be indirectly rotatably connected to the leg rod 1 via other components, such as through a sliding sleeve or connecting cap on the leg rod 1.

[0076] The roof frame 21 includes a connecting rod 211 that can rotate downwards when the tent frame body 2 is folded; a slot 41 is formed on the second end of the crossbar 4 that can engage with the connecting rod 211, the slot 41 having a downward-facing opening 410, such as... Figure 12 As shown. The slot formed by the slot portion 41 preferably extends upward from the lower surface of the slot portion 41, and the outline of the slot in the cross section of the slot portion 41 perpendicular to the length direction of the connecting rod 211 is generally an inverted U-shape. When the tent frame body 2 is folded, the connecting rod 211 will rotate downward, thereby disengaging from the slot of the slot portion 41, and the crossbar 4 and the eaves frame 21 will be disconnected, avoiding the tent frame body 2 from being unable to be folded due to forgetting to fold the eaves pole 3, or damage to the eaves pole 3 and the poles of the tent frame body 2. In this embodiment, the eaves pole 3 does not open along the diagonal direction of the tent; as Figure 3 and Figure 4 As shown, each eaves rod 3 extends along the length of the first eaves frame 21 (e.g., the eaves frame located on the front side), meaning that when viewed from above, the eaves rod 3 extends in roughly the same direction as the first eaves frame 21. The crossbar 4 connected to the eaves rod 3 is detachably connected to the second eaves frame 21, which intersects with the first eaves frame 21, for example, the eaves frame located on the left side.

[0077] Combination Figures 10b to 12 As shown, a positioning protrusion 211a is formed on the connecting rod 211 that cooperates with the crossbar 4. The slot portion 41 has a positioning groove 411 that cooperates with the positioning protrusion 211a to limit the sliding of the slot portion 41 along the length direction of the connecting rod 211. The positioning groove 411 and the slot portion 41 are interconnected and extend upward from the lower surface of the slot portion 41. During the process of the slot portion 41 engaging with the connecting rod 211, the positioning protrusion 211a enters the positioning groove 411. The positioning groove 411 has two opposing limiting walls, which are not parallel to the length direction of the connecting rod 211. The positioning protrusion 211a is located between the two limiting walls, preventing the slot portion 41 from moving back and forth on the connecting rod 211. The positioning protrusion 211a specifically includes a pin, pull stud, or rivet fixed to the connecting rod 211. In this embodiment, each crossbar 4 is composed of a single rod; while in some other embodiments, the crossbar 4 may be composed of multiple rods.

[0078] The tent also includes multiple support poles 5, each with a first end and a second end, the number and position of which correspond one-to-one with the eaves poles 3. Figure 2b , Figures 7 to 12As shown, the first end of each support rod 5 is rotatably and slidably connected to the leg rod 1 in the vertical direction, while the second end is rotatably connected to the eaves rod 3. Specifically, the first end of the support rod 5 is rotatably connected to the support base 51, and the support base 51 is slidably connected to the leg rod 1 in the vertical direction. The support base 51 is preferably a sliding sleeve that can be slidably fitted onto the leg rod 1 in the vertical direction, with the lower end of the support rod 5 pivotally connected to the sliding sleeve and the upper end pivotally connected to the eaves rod 3. An eaves locking mechanism is provided between the support base 51 and the leg rod 1, which locks the support base 51 and the leg rod 1 when the eaves rod 3 is in the open state. This eaves locking mechanism can adopt a known structure, for example, the support base 51 is provided with a movable locking member (not shown in the figure), and the leg rod 1 is provided with a locking hole 102 that cooperates with the locking member, and the locking member can be detachably inserted into the locking hole 102. When in the open state, the locking element on the support base 51 is inserted into the lock hole 102 to lock the eaves rod 3 in the open state, allowing it to unfold stably. When it needs to be converted to the folded state, press the unlock button 52 on the support base 51 to disengage the locking element from the lock hole 102. The support base 51 slides down to the lower part of the leg rod 1, causing the eaves rod 3 to fold until its outer end is close to the leg rod 1. At the same time, the first end (lower end) of the support rod 5 also comes into contact with the lower end of the leg rod 1.

[0079] Furthermore, a fixing seat 30 is provided between the inner and outer ends of the eaves pole 3, and the fixing seat 30 is located approximately in the middle of the eaves pole 3. The first end of the crossbar 4 is rotatably connected to the fixing seat 30 via a first pivot 301, and the second end (upper end) of the support rod 5 is rotatably connected to the fixing seat 30 via a second pivot 302. When the eaves pole 3 is in the folded state, the angle between the axis of the first pivot 301 and / or the second pivot 302 and the horizontal plane is less than 10 degrees. Specifically, when the eaves pole 3 is in the folded state, the axis of the first pivot 301 and the axis of the second pivot 302 are preferably parallel to the horizontal plane or inclined at only a small angle, and the axis of the pivot connecting the eaves pole 3 to the leg pole 1 is also preferably parallel to the horizontal plane or inclined at only a small angle, so that the eaves pole 3 and the crossbar 4 can automatically fall and hang beside the leg pole 1 under their own weight. Furthermore, when the eaves rod 3 is folded, the support rod 5 is close to the front and rear sides of the eaves rod 3; and, when viewed from the front or rear, the support rod 5 is completely covered by the eaves rod 3.

[0080] Combination Figure 2b , Figures 7 to 9As shown, the leg pole 1 includes a leg pole body 10 extending vertically, a fixing section 11 fixed to the upper end of the leg pole body 10, and a foot pad 12 fixed to the lower end of the leg pole body 10. The inner end of the eaves pole 3 is pivotally connected to the fixing section 11, the support seat 51 is slidably fitted onto the leg pole body 10, and the locking hole 102 is opened on the leg pole body 10. The foot pad 12 provides a large contact area with the ground, and some of the leg poles 1 (e.g., the two leg poles 1 on the right) have rollers 13 on their foot pads 12 for easy transport of the tent. Unless otherwise specified, "upper end of leg pole 1" and "lower end of leg pole 1" as mentioned below refer to the fixing section 11 and the foot pad 12, respectively.

[0081] Combination Figure 1 , Figures 3 to 5 As shown, the top frame of this embodiment includes multiple foldable eaves frames 21 and multiple foldable top pole units 22. The eaves frames 21 are connected between adjacent leg poles 1; since there are four leg poles 1, an eaves frame 21 is provided on each of the four sides of the tent. Each eaves frame 21 includes at least one connecting rod assembly 210 rotatably connected between adjacent leg poles 1. Each connecting rod assembly 210 includes two connecting rods 211 that can be unfolded and brought together relative to each other. The middle parts of the two connecting rods 211 are rotatably connected by a third pivot 212, forming a cross-shaped scissor-like structure. The upper end of the leg pole 1 (specifically, the fixed section 11) is pivotally connected to one end of a connecting rod 211 in the connecting rod assembly 210. The leg pole 1 (specifically, the leg pole body 10) is also provided with a sliding sleeve 101, which can be fitted onto the leg pole 1 in the vertical direction. The sliding sleeve 101 is pivotally connected to one end of another connecting rod 211 in the connecting rod assembly 210. When folded, the sliding sleeve 101 slides downwards, causing the two connecting rods 211 of the connecting rod assembly 210 to move laterally closer together, thus bringing the leg poles 1 closer together and reducing the size of the tent in the front-back and left-right directions. Figure 6 As shown. Specifically, in this embodiment, each eaves frame 21 is composed of three sequentially rotatably connected link assemblies 210. The aforementioned slot portion 41 is preferably detachably connected to the upper end of the link 211 that is connected to the upper end of the leg 1, and the aforementioned positioning protrusion 211a is also formed on the upper end of the link 211.

[0082] Each push rod unit 22 includes an inner push rod 222 and an outer push rod 221 rotatably connected at one end. The other end of the outer push rod 221 is rotatably connected to the upper end of the leg rod 1. The other end of the inner push rod 222 of each push rod unit 22 is rotatably connected to a central locking mechanism 23. The central locking mechanism 23 includes a top cap 231 and a bottom cap 232 that can be locked or disengaged from each other. The other end of the inner push rod 222 is rotatably connected to the top cap 231. Each push rod unit 22 also includes an auxiliary push rod 223, one end of which is rotatably connected to the inner push rod 222 and the other end of which is rotatably connected to the bottom cap 232. Each push rod unit 22 also includes a diagonal rod 224, the upper end of which is rotatably connected to the outer push rod 221 and the lower end of which is rotatably connected to the sliding sleeve 101 on the leg rod 1. When the top cap 231 and bottom cap 232 are locked, the tent frame body 2 is locked in the unfolded state by the central locking mechanism 23; when the top cap 231 and bottom cap 232 are unlocked, the diagonal rod 224 moves downward with the sliding sleeve 101, which pulls the top rod unit 22 to fold, that is, the outer top rod 221 and inner top rod 222 rotate downward, so that the inner end of the outer top rod 221 and the outer end of the inner top rod 222 move closer to the lower end of the leg rod 1, the upper end of the top cap 231 and the upper end of the leg rod 1 move closer to each other, and the lower end of the auxiliary top rod 223 and the outer end of the bottom cap 232 and the inner top rod 222 move closer to each other.

[0083] The tent frame body 2 also includes a reinforcing mechanism 6 connecting the eaves frame 21 and the central locking mechanism 23. Specifically, the reinforcing mechanism 6 includes an outer reinforcing rod 621 and an inner reinforcing rod 622 rotatably connected at one end. The other end of the outer reinforcing rod 621 is rotatably connected to the eaves frame and rotatably connected to the central locking mechanism 23, specifically the top cap 231. The reinforcing mechanism 6 also includes an auxiliary reinforcing rod 623, one end of which is rotatably connected to the inner reinforcing rod 622 and the other end of which is rotatably connected to the bottom cap 232. In this embodiment, the other end of the outer reinforcing rod 621 is rotatably connected to the cross connection of the intermediate connecting rod assembly 210. Specifically, the other end of the outer reinforcing rod 621 is rotatably connected to a connector 624 via a fourth pivot 621a. The connector 624 is fixedly connected to a third pivot 212. The axis of the fourth pivot 621a and the axis of the third pivot 212 form an angle greater than zero and less than 180 degrees, preferably perpendicular to each other. The tent in this embodiment has two reinforcing mechanisms 6, respectively located on the left and right sides of the top frame.

[0084] The tent is used as follows: Unfold the tent frame body 2. After unfolding, lock the top cap 231 and bottom cap 232 together to ensure stable tent unfolding. Figure 1 As shown, the eaves rod 3 on one side can be opened as needed, such as... Figure 3As shown; or choose to open the eaves rods 3 on both sides, as shown. Figure 4 and 5 As shown. The specific process of opening the eaves pole 3 is as follows: the eaves pole 3 is lifted, the support base 51 moves upward accordingly, and the second end of the crossbar 4 is locked onto the positioning protrusion 211a on the connecting rod 211. The eaves locking mechanism locks the eaves pole 3 in its open state. The specific process of folding the eaves pole 3 is as follows: the eaves locking mechanism is unlocked, the second end of the crossbar 4 is disengaged from the connecting rod 211, and under its own weight, the support base 51 slides down, and the eaves pole 3 and the crossbar 4 automatically droop to the side of the leg body 10. When the tent needs to be folded up, the eaves pole 3 can be folded up in advance; if it is forgotten to be folded up, the crossbar 4 can be automatically released from the connecting rod 211 under the pressure of external force during the folding process of the tent frame body 2. Specifically, the top cap 231 and bottom cap 232 are unlocked, the sliding sleeve 101 on the leg body 10 moves down, and the connecting rods 211 of the eaves frame 21 rotate and move closer to each other. In particular, the connecting rod 211 connected to the crossbar 4 rotates downward and disengages from the slot 410 on the slot 41, and the tent frame body 2 is folded up normally.

[0085] After unfolding, the tent can flexibly open or close the eaves pole 3 as needed, and the opening and closing are quick and convenient. The crossbar 4 can be reinforced after the eaves pole 3 is opened, providing good strength. In particular, when folding the tent, if the eaves pole 3 is forgotten to be closed, as the eaves frame 21 is folded, the second end of the crossbar 4 can automatically disengage from the connecting rod 211 of the eaves frame 21 under external force, preventing the eaves pole 3 from accidentally breaking or the structure of the tent frame body 2 from being damaged due to forgetting to close it. In addition, a foldable reinforcing mechanism 6 is provided between the eaves frame 21 and the central locking mechanism 23, which can offset or reduce the thrust of the crossbar 4 on the eaves frame 21 while the tent frame body 2 is unfolded and folded, avoiding the problem of inward deformation of the eaves frame 21 caused by the thrust of the crossbar 4. The tent frame body 2 is locked by the central locking mechanism 23, allowing for quick opening and closing.

[0086] Example 2

[0087] This embodiment is basically the same as Embodiment 1, except that the reinforcing mechanism 6 is different. (Refer to...) Figures 14 to 16As shown, the reinforcing mechanism 6 in this embodiment is connected between the eaves frame 21 and the top rod unit 22. The reinforcing mechanism 6 includes a reinforcing rod 610, one end of which is rotatably connected to the inner top rod 222, and the other end is rotatably connected to the eaves frame 21 (specifically, the upper rotatable connection point of two adjacent link assemblies 210). Specifically, one end of the reinforcing rod 610 is pivotally connected to the inner top rod 222, and the distance between the connection point and the inner end of the inner top rod 222 is less than one-third of the length of the inner top rod 222; the other end of the reinforcing rod 610 is pivotally connected to a connector 611, through which the link 211 of the two adjacent link assemblies 210 is rotatably connected. The tent in this embodiment has eight reinforcing rods 610. Each eaves frame 21 is rotatably connected to the inner top rod 222 of two adjacent top rod units 22 via two reinforcing rods 610. This connects the four sets of eaves frames 21 and top rod units 22 to form a reinforcing structure, thereby reducing the problem of inward deformation of the eaves frame 21 caused by the thrust of the crossbar 4. The reinforcing rods 610 can rotate accordingly with the unfolding and folding of the tent frame body 2 without affecting the unfolding and folding of the tent frame body 2.

[0088] Figure 14 A tent with a canopy 70 is shown. The two eaves poles 3 on the left are open, thus the canopy 70 on the left is raised to increase the coverage area; while the two eaves poles 3 on the right are not open, and the canopy 70 on the right hangs down on the right side of the tent, specifically to the right of the two right leg poles 1.

[0089] Example 3

[0090] This embodiment is basically the same as Embodiment 1, except that the connection method between the eaves pole 3 and the main body of the tent frame is different; combined with Figures 17 to 19 As shown, the eaves pole 3 is detachably inserted into the leg pole 1, rather than being rotatably connected to the leg pole 1. Specifically, the inner end of the eaves pole 3 is detachably inserted into the leg pole 1 via a sliding sleeve 101 on the leg pole 1. The sliding sleeve 101 is provided with a slot 101a, which extends generally at an angle. When the eaves pole 3 is in the open state, the inner end of the eaves pole 3 is inserted into the slot 101a and connected to the leg pole 1; when the eaves pole 3 is in the folded state, the inner end of the eaves pole 3 is pulled out of the slot 101a and detached from the leg pole 1. Although the crossbar is not shown, it can also automatically detach from the eaves frame 21 when the tent frame body is folded.

[0091] Example 4

[0092] This embodiment is basically the same as Embodiment 1, except that the connection method between the eaves pole 3 and the main body of the tent frame is different; combined with Figure 20 and Figure 21As shown, the eaves pole 3 is detachably inserted into the leg pole 1, rather than being rotatably connected to the leg pole 1. Specifically, the inner end of the eaves pole 3 is detachably inserted into the fixing section 11 of the leg pole 1. The fixing section 11 is provided with a slot 11a, which extends generally at an angle. When the eaves pole 3 is in the open state, the inner end of the eaves pole 3 is inserted into the slot 11a and connected to the leg pole 1; when the eaves pole 3 is in the folded state, the inner end of the eaves pole 3 is pulled out from the slot 11a and detached from the leg pole 1. Although the crossbar is not shown, it can also automatically detach from the eaves frame 21 when the tent frame body is folded.

[0093] Example 5

[0094] This embodiment is basically the same as Embodiment 1, except that the connection method of the eaves rod 3, the horizontal bar 4, and the support rod 5 is different. Specifically, combined with Figures 22 to 24 As shown, the fixed seat 30 on the eaves rod 3 is rotatably connected to a rotating seat 31. The first end of the crossbar 4 and the rotating seat 31 are rotatably connected via pivot a1, and the second end of the support rod 5 and the fixed seat 30 are rotatably connected via pivot a2. Furthermore, the rotating seat 31, the fixed seat 30, and the second end of the support rod 5 are rotatably connected via pivot a2.

[0095] Example 6

[0096] This embodiment is basically the same as Embodiment 1, except that the connection method of the eaves rod 3, the horizontal bar 4, and the support rod 5 is different. Specifically, combined with Figures 25 to 27 As shown, the first end of the crossbar 4 is rotatably connected to the fixed seat 30 on the eaves rod 3 via a universal swivel joint 32, and the second end of the support rod 5 is rotatably connected to the fixed seat 30 via a pivot a3.

[0097] Regardless of which of the three connection methods, namely Embodiment 1, Embodiment 5, or Embodiment 6, when the eaves rod 3 is in the folded state, the lower end of the eaves rod 3, the second end of the crossbar 4, the first end of the support rod 5, and the leg rod 1 are close to each other.
