This application claims priority to the Chinese patent application No. CN2022103293437, filed on March 28, 2022.

This disclosure pertains to the field of outdoor equipment and relates to a folding tent, specifically a folding tent with a canopy pole.

Tents are widely used in outdoor activities such as camping, providing protection from wind, rain, and insects, as well as insulation. Existing folding tents have a small shaded area. To increase the shaded area after opening, tents with awnings have emerged. These tents feature awning poles extending from the apex corners, and the surrounding fabric attached to these poles increases the shaded area. In such tents, the awning poles are primarily pivotally attached to push rods that form the brackets at the top of the tent, or inserted into them. After the tent body is deployed, the awning can be selectively extended to increase the shaded area. However, conventional tents of this type may have a problem with insufficient strength after the awning poles are extended.

One aspect of this disclosure relates to an improved folding tent that allows for flexible selection of whether to open or fold the canopy poles according to demand, and simultaneously provides superior strength after the canopy poles are opened.

One aspect of this disclosure is,
A tent frame body comprising multiple leg poles and multiple canopy frames, wherein each canopy frame is connected between two adjacent leg poles,
After the folding tent is unfolded, it takes on an open state, and when in the open state, its inner end is connected to the tent frame body, and its outer end is offset by a certain distance from the leg pole, and a canopy pole crosses the leg pole,
A folding tent is provided, which includes a crossbar at both ends for connecting to one of the plurality of canopy frames and the canopy pole, respectively, wherein the folding tent includes a crossbar that reinforces the strength of the canopy pole when the canopy pole is in the open position.

In one embodiment, the folding tent further includes an enclosure fabric. After the folding tent is unfolded, the canopy poles have a further folded state. When the canopy poles are in the open state, they are positioned to support the enclosure fabric and open. When the canopy poles are in the folded state, the enclosure fabric hangs down to the side of the tent frame body. After unfolding, the canopy poles can be flexibly opened or retracted as needed, and opening and closing are quick and convenient. In particular, after the canopy poles are opened, a crossbar is provided and connected between the canopy poles and the canopy frame to give the canopy poles good strength after they are opened.

In one embodiment, the crossbar has a first end rotatably connected to the canopy pole and a second end detachably connected to one of the plurality of canopy frames. When the canopy pole is folded, the second end of the crossbar detaches from the canopy frame, bringing the outer end of the canopy pole close to one of the plurality of leg poles. When the canopy pole is open, the second end of the crossbar is connected to the canopy frame, and the outer end of the canopy pole is shifted a certain distance from one of the plurality of leg poles. In the process of switching the folding tent from an unfolded state to a folded state, the second end of the crossbar detaches from the canopy frame, and the canopy pole is converted from an open state to a folded state. The tent allows for flexible selection of whether to open or store the canopy pole, while simultaneously avoiding damage to the tent structure during folding due to forgetting to store the canopy pole. After deployment, the awning poles can be flexibly opened or retracted as needed, and both opening and retraction are quick and convenient. In particular, when folding the tent, if the awning poles are forgotten, the second end of the crossbar automatically detaches from the awning frame's link due to external force during folding. This prevents the awning poles from being accidentally broken or the tent frame's structure from being damaged due to forgetting to retract them.

In one embodiment, the inner end of the canopy pole is rotatably connected to one of the plurality of leg poles, and the tent further comprises a support rod having a first end and a second end, the first end being rotatably and vertically slidably connected to one of the plurality of leg poles, and the second end being rotatably connected to the canopy pole.

In one embodiment, the first end of the support rod is rotatably connected to the support base, and the support base is slidably connected vertically to one of the plurality of leg poles.

In one embodiment, a canopy locking mechanism is provided between the support base and the leg pole, and when the canopy pole is in the open position, the canopy locking mechanism locks the support base and the leg pole together.

In one embodiment, a fixing sheet is provided between the inner and outer ends of the canopy pole, the first end of the crossbar is rotatably connected to the fixing sheet via a first pivot axis, and the second end of the support rod is connected to the fixing sheet via a second pivot axis. When the canopy pole is folded, the angle between the axes of the first pivot axis and/or the second pivot axis and the horizontal plane is less than 10 degrees. When the canopy pole is folded, the axes of the first pivot axis and the second pivot axis are preferably parallel to the horizontal plane or tilted at only a slight angle, so that the canopy pole and crossbar can automatically fall due to their own gravity and hang down beside the leg pole, reinforcing the leg pole.

In one embodiment, a fixed sheet is provided between the inner and outer ends of the canopy pole, the fixed sheet and the turntable are rotatably connected, one of the first end of the crossbar and the second end of the support rod is rotatably connected to the fixed sheet, and the other is rotatably connected to the turntable.

In one embodiment, a fixing sheet is provided between the inner and outer ends of the canopy pole. One of the pivot axes—the first end of the crossbar and the second end of the support rod—is connected to the fixing sheet, while the other is rotatably connected to the fixing sheet via a universal rotary joint.

In one embodiment, when the canopy pole is folded, the support rod approaches the front or rear of the canopy pole, and when viewed from the front or rear, the support rod is completely hidden by the canopy pole.

In one embodiment, when the canopy pole is in a folded state, the outer end of the canopy pole and the first end of the support rod approach the lower end of one of the plurality of leg poles.

In one embodiment, at least one of the plurality of canopy frames is provided with a link that can rotate downward when the tent frame body is folded, and a slot portion that can engage with the link is formed at the second end of the crossbar.

In one embodiment, the slot portion has a downward-facing slot opening.

In one embodiment, the slot formed from the slot portion extends upward from the lower surface of the slot portion. Furthermore, in a cross-section perpendicular to the longitudinal direction of the link of the slot portion, the contour of the slot is approximately an inverted U-shape.

In one embodiment, the link has a positioning bump, and the slot portion has a positioning slot that fits into the positioning bump. Furthermore, the positioning slot has two opposing stopper walls, the stopper walls as a whole are not parallel to the longitudinal direction of the link, and the positioning bump is located between the two stopper walls, preventing the slot portion from moving back and forth.

In one embodiment, the outer end of the canopy pole is connected to the enclosure fabric, so that the enclosure fabric can be spread out to provide shade or hung down to the side of the tent structure.

In one embodiment, the canopy pole is detachably inserted into one of the plurality of leg poles, and when the canopy pole is in the open state, the inner end of the canopy pole is inserted into one of the plurality of leg poles, and when the canopy pole is in the folded state, the inner end of the canopy pole is detached from the leg pole.

In one embodiment, the canopy pole extends along the length of one of the canopy frames when it is in the open position.

In one embodiment, each of the leg poles corresponds to at least one of the canopy poles, and each of the canopy poles is connected to at least one of the crossbars.

In one embodiment, when the folding tent is folded, the canopy poles bias the crossbars so that the crossbars automatically detach from the canopy frame.

In one embodiment, the tent frame body further comprises a plurality of foldable pushrod units, each of which comprises an inner pushrod and an outer pushrod, each having one end rotatably connected, the other end of the outer pushrod rotatably connected to the upper end of the leg pole, and the other end of the inner pushrod of each pushrod unit rotatably connected to a center lock mechanism. The tent frame body further comprises at least one reinforcing mechanism connected between the canopy frame and the pushrod units, or between the canopy frame and the center lock mechanism. The reinforcing mechanism can offset or reduce the thrust of the canopy frame by the crossbar and avoid the problem of inward concave deformation of the canopy frame due to the pre-tension of the crossbar.

In one embodiment, the reinforcing mechanism includes a reinforcing rod, the reinforcing rod having one end rotatably connected to the internal push rod and the other end rotatably connected to the canopy frame.

In one embodiment, the reinforcing mechanism comprises an outer reinforcing rod and an inner reinforcing rod, one end of which is rotatably connected, the other end of which is rotatably connected to the canopy frame, and the other end of which is rotatably connected to the center lock mechanism.

The advantages and features of this disclosure will be readily apparent to those skilled in the art, by describing preferred embodiments in detail below with reference to the accompanying drawings. It should be noted that these descriptions of embodiments are provided to aid in understanding this disclosure, but do not constitute limitations thereof. Furthermore, the technical features included in the various embodiments of this disclosure described below can be combined with each other, insofar as they do not conflict with each other.

Figures 1 to 12 show an example of a folding tent. As shown in Figures 1 to 12, the folding tent has an unfolded state and a folded state, and comprises a foldable tent frame body 2, which can be independently supported on the ground, and is covered with a fabric cover (not shown) to protect from the sun, wind, rain, etc., and a part of the fabric cover (e.g., the edge) can hang down to the side of the tent frame body 2, and this part of the fabric cover is called the enclosure fabric. As shown in Figures 1 and 3 to 5, the tent frame body 2 comprises a plurality of leg poles 1 extending in the vertical direction and a canopy connected to the top of the leg poles 1, and is supported on the ground via the leg poles 1, with the fabric cover mainly covering the canopy. The tent further comprises canopy poles 3 having inner and outer ends, the inner ends of the canopy poles 3 being rotatably connected to the leg poles 1, specifically via pivot axes. There are multiple canopy poles 3, and their number and position correspond one-to-one with the leg poles 1. That is, the inner end of each canopy pole 3 is rotatably connected to the corresponding leg pole 1, and the aforementioned enclosure fabric is connected to the outer end of the canopy pole 3. Supported by the canopy poles 3, it can be opened to increase the shaded area as a canopy, and when the canopy poles 3 are folded, it hangs down to the side of the tent and can be used as a side enclosure fabric. Each canopy pole 3 has a folded state and an open state. When the canopy pole 3 is folded, it approaches the leg pole 1, and when it is open, it is offset by a certain distance from the leg pole 1. In other words, the canopy pole 3 has a folded state that approaches the leg pole 1 and an open state that is unfolded relative to the leg pole 1. After the canopy poles 3 are unfolded, the enclosure fabric can be spread outwards to increase the shaded area of the tent. Furthermore, when the left awning pole 3 is in the open position, it extends to the left, meaning its outer end is located to the left of the leg pole 1. Similarly, when the right awning pole 3 is in the open position, it extends to the right, meaning its outer end is located to the right of the leg pole 1. Therefore, it supports and opens the left and right side enclosure fabrics, increasing the awning area on both the left and right sides of the tent, thereby increasing the sunshade area on both sides. When the awning poles 3 are folded, the enclosure fabric hangs down and is located towards the tent.

The canopy comprises a plurality of foldable awning frames 21, which are connected between adjacent leg poles 1. The tent further comprises a plurality of crossbars 4, the number and position of which correspond one-to-one with the plurality of awning poles 3. As shown in Figures 7 to 12, each crossbar 4 has a first end that is rotatably connected to an awning pole 3 and a second end that is detachably connected to an awning frame 21. When the awning poles 3 are folded, the second end of the crossbar 4 is detached from the awning frame 21, and when the awning poles 3 are open, the second end of the crossbar 4 is connected to the awning frame 21. In the process of switching the tent frame body 2 from an unfolded state to a folded state, the second end of the crossbar 4 is detached from the awning frame 21, and the awning poles 3 are switched from an open state to a folded state. The second end of the crossbar 4 and the lever on the canopy frame 21 use a detachable connection method, allowing them to automatically detach from the canopy frame 21 when the canopy frame 21 is folded, receiving force from the canopy pole 3. One implementation method will be described in detail below.

In this embodiment, the canopy pole 3 is directly and rotatably connected to the leg pole 1 via a pivot axis. In some other embodiments, the canopy pole 3 is indirectly and rotatably connected to the leg pole 1 via other components, such as a sliding sleeve or connecting cap on the leg pole 1.

The canopy frame 21 includes a link 211 that can rotate downward when the tent frame body 2 is folded, and a slot portion 41 formed at the second end of the crossbar 4 that can engage with the link 211. As shown in Figure 12, the slot portion 41 has a downward-facing slot opening 410. Preferably, the slot formed from the slot portion 41 extends upward from the lower surface of the slot portion 41 and, in a cross section perpendicular to the length direction of the link 211 of the slot portion 41, the contour of the slot is approximately an inverted U shape. When the tent frame body 2 is folded, the link 211 rotates downward and disengages from the slot of the slot portion 41, releasing the connection between the crossbar 4 and the canopy frame 21, thus preventing the tent frame body 2 from being folded due to forgetting to fold the canopy pole 3, or damaging the levers of the canopy pole 3 and the tent frame body 2. In this embodiment, the canopy poles 3 do not open diagonally along the tent, but rather, as shown in Figures 3 and 4, each canopy pole 3 extends in the longitudinal direction of the first canopy frame 21 (for example, the canopy frame on the front side). That is, in a plan view, the canopy poles 3 are approximately in the same direction as the extension of the first canopy frame 21. The crossbars 4, which are in contact with the canopy poles 3, are detachably connected to the second canopy frame 21, and this second canopy frame 21 intersects with the first canopy frame 21, for example, the canopy frame on the left side.

As shown in Figures 10b to 12, a positioning bump 211a is formed on the link 211 that fits onto the crossbar 4, and the slot portion 41 has a positioning slot 411 that fits onto the positioning bump 211a so as to restrict the sliding of the slot portion 41 in the longitudinal direction of the link 211. The positioning slot 411 and the slot formed from the slot portion 41 are in communication with each other and extend upward from the lower surface of the slot portion 41, and in the process of the slot portion 41 engaging with the link 211 the positioning bump 211a enters the positioning slot 411, and the positioning slot 411 has two opposing stopper walls, the stopper walls as a whole are not parallel to the longitudinal direction of the link 211, and the positioning bump 211a is located between the two stopper walls, preventing the slot portion 41 from moving the link 211 back and forth. The positioning bump 211a specifically comprises a pin, blind rivet, or rivet fixed to the link 211, and furthermore, the positioning bump 211a is located at the pivot point between the link 211 and another lever (preferably another lever on the canopy frame), and may be part of the pivot axis that pivots the link 211 and the other lever, or may be provided on the pivot axis. In this embodiment, each crossbar 4 consists of a single rod, but in some other embodiments, the crossbar 4 may consist of multiple levers.

The tent further comprises support rods 5 having a first end and a second end, and there are multiple support rods 5, with the number and position of the multiple support rods 5 corresponding one-to-one with the multiple canopy poles 3. As shown in Figures 2b, 7 to 12, each support rod 5 has its first end rotatably and vertically slidably connected to a leg pole 1, and its second end rotatably connected to a canopy pole 3. Specifically, the first end of the support rod 5 is rotatably connected to a support base 51, and the support base 51 is vertically slidably connected to the leg pole 1. Preferably, the support base 51 can be vertically slidably fitted onto a sliding sleeve on the leg pole 1, and the lower end of the support rod 5 is pivotally connected to the sliding sleeve, and the upper end is pivotally connected to the canopy pole 3. A canopy locking mechanism is provided between the support base 51 and the leg pole 1, and when the canopy pole 3 is in the open position, the canopy locking mechanism locks the support base 51 and the leg pole 1. A known structure can be used for the canopy locking mechanism. For example, the support base 51 is provided with a movable locking piece (not shown), and the leg pole 1 is provided with a keyhole 102 that fits into the locking piece. The locking piece is detachably inserted into the keyhole 102. When in the open position, the locking piece on the support base 51 is inserted into the keyhole 102, locking the canopy pole 3 in the open position for stable deployment. When it is necessary to convert to the folded position, pressing the unlock button 52 on the support base 51 releases the locking piece from the keyhole 102, causing the support base 51 to slide down to the bottom of the leg pole 1. This drives the canopy pole 3 to fold until its outer end approaches the leg pole 1. Simultaneously, the first end (lower end) of the support rod 5 also approaches the lower end of the leg pole 1.

Furthermore, a fixing sheet 30 is provided between the inner and outer ends of the canopy pole 3, and the fixing sheet 30 is located approximately in the middle of the canopy pole 3. The first end of the crossbar 4 is rotatably connected to the fixing sheet 30 via a first pivot shaft 301, and the second end (upper end) of the support rod 5 is rotatably connected to the fixing sheet 30 via a second pivot shaft 302. When the canopy pole 3 is in the folded state, the angle between the axes of the first pivot shaft 301 and/or the second pivot shaft 302 and the horizontal plane is less than 10 degrees. Specifically, when the canopy pole 3 is in the folded state, the axes of the first pivot axis 301 and the second pivot axis 302 are preferably parallel to the horizontal plane or tilted at only a slight angle. Furthermore, the axis of the pivot axis connecting the canopy pole 3 and the leg pole 1 is also preferably parallel to the horizontal plane or tilted at only a slight angle. Therefore, the canopy pole 3 and crossbar 4 can automatically fall due to gravity and hang down beside the leg pole 1. Moreover, when the canopy pole 3 is in the folded state, the support rod 5 approaches the front or rear side of the canopy pole 3, and when viewed from the front or rear, the support rod 5 is completely hidden by the canopy pole 3.

As shown in Figures 2b, 7 to 9, the leg pole 1 comprises a leg pole body 10 extending vertically, a fixed joint 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 canopy pole 3 is pivotally connected to the fixed joint 11, the support base 51 is slidably fitted onto the leg pole body 10, and a keyhole 102 is opened in the leg pole body 10. The foot pad 12 provides a relatively large contact area with the ground, and some of the foot pads 12 of the leg poles 1 (for example, the two right-hand leg poles 1) are provided with rollers 13 for transporting the tent. Unless otherwise specified, “upper end of leg pole 1” and “lower end of leg pole 1” below refer to the fixed joint 11 and the foot pad 12, respectively. Furthermore, some or all of the foot pads 12 are provided with insertion slots, allowing a protective bag with a lower opening to cover the tent after it has been folded. The lower end of the protective bag is secured to the insertion slot by a connecting assembly, and the protective bag is secured to the tent by, for example, inserting a plug in the connecting tape into the insertion slot of the foot pad 12.

As shown in Figures 1, 3 to 5, the canopy of this embodiment comprises a plurality of foldable canopy frames 21 and a plurality of foldable push rod units 22. The canopy frames 21 are connected between interconnected leg poles 1, and there are four leg poles 1, so that one canopy frame 21 is provided on each of the four sides of the tent (front, back, left, and right). Each canopy frame 21 comprises at least one link assembly 210 that is rotatably connected between adjacent leg poles 1, and each link assembly 210 comprises two links 211 that can be deployed or brought closer together, and the middle portions of the two links 211 are rotatably connected via a third pivot shaft 212, forming a staggered clamp-like structure. The upper end of the leg pole 1 (specifically, the fixed joint 11) is pivotally connected to one end of one link 211 of the link assembly 210 that is adjacent to it. The leg pole 1 (specifically the leg pole body 10) is further provided with a sliding sleeve 101, which is fitted onto the leg pole 1 so as to be slidable in the vertical direction, and the sliding sleeve 101 is pivotally connected to one end of the other link 211 of the link assembly 210. When folded, the sliding sleeve 101 slides downward, and the two links 211 of the link assembly 210 move closer to each other in the horizontal direction, bringing the leg poles 1 closer to each other and reducing the size of the tent in the front, back, left, and right directions, as shown in Figure 6. Specifically, in this embodiment, each canopy frame 21 is composed of three link assemblies 210 that are sequentially rotatably connected. The aforementioned slot portion 41 is preferably detachably connected to the upper end of the link 211 to which the upper end of the leg pole 1 is connected, and the aforementioned positioning bump 211a is also formed on the upper end of the link 211.

Each push rod unit 22 comprises an inner push rod 222 and an outer push rod 221, one end of which is rotatably connected. The other end of the outer push rod 221 is rotatably connected to the upper end of the leg pole 1. The other end of the inner push rod 222 of each push rod unit 22 is rotatably connected to a center lock mechanism 23. The center lock mechanism 23 comprises a top cap 231 and a bottom cap 232 that can engage or disengage with 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 comprises 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 is equipped with an inclined 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 pole 1. After the top cap 231 and bottom cap 232 engage, the tent frame body 2 is locked in the deployed state by the center lock mechanism 23. After the engagement between the top cap 231 and bottom cap 232 is released, the inclined rod 224 moves downward with the sliding sleeve 101, driving the push rod unit 22 to fold. This causes the outer push rod 221 and inner push rod 222 to rotate downward, so that the inner end of the outer push rod 221 and the outer end of the inner push rod 222 approach the lower end of the leg pole 1, the top cap 231 and the upper end of the leg pole 1 approach each other, and the lower end of the auxiliary push rod 223 and the bottom cap 232 and the outer end of the inner push rod 222 approach each other.

The tent frame body 2 further includes a reinforcing mechanism 6 connected between the canopy frame 21 and the center lock mechanism 23. Specifically, the reinforcing mechanism 6 comprises an outer reinforcing rod 621 and an inner reinforcing rod 622, one end of which is rotatably connected. The other end of the outer reinforcing rod 621 is rotatably connected to the canopy frame, and the other end of the outer reinforcing rod 621 is rotatably connected to the center lock mechanism 23, specifically to the top cap 231. The reinforcing mechanism 6 further 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 intersection connection point of the central link assembly 210. Specifically, the other end of the outer reinforcing rod 621 is rotatably connected to the connector 624 via the fourth pivot shaft 621a, and the connector 624 is fixedly connected to the third pivot shaft 212. The axis of the fourth pivot shaft 621a and the axis of the third pivot shaft 212 form an angle greater than 0 and less than 180 degrees, and are preferably perpendicular to each other. The tent in this embodiment has two reinforcing mechanisms 6, which are provided on the left and right sides of the canopy, respectively.

The method of using the tent is as follows: The tent frame body 2 is unfolded, and after unfolding, the top cap 231 and bottom cap 232 are engaged with each other to stably unfold the tent. As shown in Figure 1, or as needed, one side of the canopy pole 3 may be opened as shown in Figure 3, or both sides of the canopy pole 3 may be opened as shown in Figures 4 and 5. The specific process of opening the canopy pole 3 is as follows: The canopy pole 3 is lifted, the support base 51 moves upward accordingly, the second end of the crossbar 4 engages with the positioning bump 211a on the link 211, the canopy locking mechanism is locked, and the canopy pole 3 is stably in its open state. The specific process of folding the canopy pole 3 is as follows: The canopy locking mechanism is unlocked, the second end of the crossbar 4 is released from the link 211, the support base 51 slides downward due to gravity, and the canopy pole 3 and crossbar 4 automatically hang down to the side of the leg pole body 10. When folding the tent, the canopy poles 3 may be folded beforehand. If this is forgotten, during the folding process of the tent frame body 2, the external force pressing down will automatically detach the crossbar 4 from the link 211 and release it. Specifically, the top cap 231 and bottom cap 232 will be unlocked, the sliding sleeve 101 on the leg pole body 10 will move downward, the links 211 of the canopy frame 21 will rotate toward each other, and in particular the link 211 connected to the crossbar 4 will rotate downward, detach from the slot opening 410 in the slot section 41, and the tent frame body 2 will fold normally.

The tent allows for flexible selection of whether to open or retract the awning poles 3 after deployment, depending on the need. Opening and retracting are quick and convenient. The crossbar 4 can reinforce the awning poles 3 after they are opened, providing good strength. In particular, when folding the tent, if the awning poles 3 are forgotten, the second end of the crossbar 4 can automatically detach from the link 211 of the awning frame 21 due to external force during folding. This prevents the awning poles 3 from being accidentally broken or the structure of the tent frame body 2 from being damaged due to forgetting to retract them. Furthermore, by providing a foldable reinforcing mechanism 6 between the awning frame 21 and the center lock mechanism 23, the thrust of the awning frame 21 by the crossbar 4 can be offset or reduced simultaneously during deployment and folding of the tent frame body 2, avoiding the problem of the awning frame 21 deforming into a concave shape due to the thrust of the crossbar 4. The tent frame body 2 can be locked by the center lock mechanism 23 and opened or retracted.

Figures 14 to 16 show another example of a folding tent, the only difference from the folding tent described above being the difference in the reinforcing mechanism 6. As shown in Figures 14 to 16, the reinforcing mechanism 6 of this embodiment is connected between the canopy frame 21 and the push rod unit 22. The reinforcing mechanism 6 comprises a reinforcing rod 610, one end of which is rotatably connected to an internal push rod 222, and the other end of which is rotatably connected to the canopy frame 21 (specifically, a pivot connection point above two adjacent link assemblies 210). Specifically, one end of the reinforcing rod 610 is pivotally connected to the internal push rod 222, and the distance between the connection point and the inner end of the internal push rod 222 is less than one-third of the length of the internal push rod 222, and the other end of the reinforcing rod 610 is pivotally connected to a connection head 611, and the links 211 of the two adjacent link assemblies 210 described above are rotatably connected via the connection head 611. The tent in this embodiment is equipped with eight reinforcing rods 610. Each canopy frame 21 is rotatably connected to the push rods 222 within two adjacent push rod units 22 via two reinforcing rods 610. Four sets of canopy frames 21 and push rod units 22 are connected to form a reinforcing structure, reducing the problem of inward concave deformation of the canopy frame 21 due to the thrust of the crossbar 4. The reinforcing rods 610 can rotate in response to the deployment and folding of the tent frame body 2, without affecting the deployment and folding of the tent frame body 2.

Figure 14 shows a tent with a perimeter fabric 70. Because the two left-side canopy poles 3 are open, the left-side perimeter fabric 70 is supported and used to increase the shaded area. On the other hand, the two right-side canopy poles 3 are not open, and the right-side perimeter fabric 70 is perpendicular to the right side of the tent, specifically located to the right of the two right-side leg poles 1. Furthermore, the connection points of the crossbar 4 and the canopy frame 21 are lower than the perimeter fabric 70.

Figures 17 to 19 show another example of a folding tent, and the only difference from the folding tent shown in Figures 1 to 12 is the method of connecting the canopy pole 3 to the tent frame body. As shown in Figures 17 to 19, the canopy pole 3 is not rotatably connected to the leg pole 1, but is detachably inserted into the leg pole 1. Specifically, the inner end of the canopy 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 at an angle. When the canopy pole 3 is in the open position, the inner end of the canopy pole 3 is inserted into the slot 101a and connected to the leg pole 1, and when the canopy pole 3 is in the folded position, the inner end of the canopy pole 3 is pulled out of the slot 101a and detached from the leg pole 1. When the tent frame body is folded, the crossbar 4 can similarly be automatically detached from the link 211 of the canopy frame 21.

Figures 20 and 21 show a fourth example of a folding tent. The only difference from the folding tents shown in Figures 1 to 12 is the connection method between the canopy pole 3 and the tent frame body. As shown in Figures 20 and 21, the canopy pole 3 is not rotatably connected to the leg pole 1, but rather detachably inserted into the leg pole 1. Specifically, the inner end of the canopy pole 3 is detachably inserted into the fixed joint 11 of the leg pole 1. The fixed joint 11 is provided with a slot 11a, which extends at an approximate angle. When the canopy pole 3 is in the open position, the inner end of the canopy pole 3 is inserted into the slot 11a and connected to the leg pole 1. When the canopy pole 3 is in the folded position, the inner end of the canopy pole 3 is pulled out of the slot 11a and detached from the leg pole 1. Similarly, when the tent frame body is folded, the crossbar 4 can automatically detach from the link 211 of the canopy frame 21.

Figures 22 to 24 show a fifth example of a folding tent. The only difference from the folding tents shown in Figures 1 to 12 is the connection method of the three components: the canopy pole 3, the crossbar 4, and the support rod 5. Specifically, as shown in Figures 22 to 24, the fixed sheet 30 on the canopy pole 3 is rotatably connected to the turntable 31; the first end of the crossbar 4 is rotatably connected to the turntable 31 via a pivot axis a1; and the second end of the support rod 5 is rotatably connected to the fixed sheet 30 via a pivot axis a2. Furthermore, the turntable 31, the fixed sheet 30, and the second end of the support rod 5 are rotatably connected via the pivot axis a2.

Figures 25 to 27 show a sixth example of a folding tent. The only difference from the folding tents shown in Figures 1 to 12 is the connection method of the canopy pole 3, crossbar 4, and support rod 5. Specifically, as shown in Figures 25 to 27, the first end of the crossbar 4 is rotatably connected to the fixed sheet 30 on the canopy pole 3 via a universal rotary joint 32, and the second end of the support rod 5 is rotatably connected to the fixed sheet 30 via a pivot shaft a3.

Regardless of which of the three connection methods described above is adopted, when the canopy pole 3 is in the folded state, the lower end of the canopy pole 3, the second end of the crossbar 4, and the first end of the support rod 5 will be close to each other and to the leg pole 1.
