Foldable tent

[0001] This disclosure claims priority to Chinese patent applications CN2024218504948 and CN2024218538041, filed on August 1, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to a foldable tent. Background Technology

[0003] Folding tents are widely used in people's daily lives. Most folding tents need to be folded to reduce their size before transportation to facilitate movement and handling. However, due to bumps and vibrations during transportation and collisions with other goods, the tents are easily deformed, and the poles may be squeezed and collided, causing damage to the tent. To avoid the above situations, some tents are packed into boxes or storage bags after folding. However, the boxes or storage bags are also squeezed, which affects the tent inside and cannot completely prevent damage to the tent.

[0004] Packaging boxes or storage bags usually have wheels to allow users to move the tent by dragging it. However, stuffing the folded tent into the box is often cumbersome and time-consuming, and the box is easily damaged with repeated use. Some tents have wheels directly attached to the tent frame, allowing users to pull the frame directly, but the wheels increase the tent's size and shape, making storage difficult.

[0005] Public content

[0006] This disclosure provides a foldable tent, including a tent frame having an unfolded state and a folded state. The tent frame includes at least three support legs and a foldable telescopic unit connected between the support legs. In the folded state, the support legs are close together, and the telescopic unit is folded between the support legs. At least two of the support legs have rollers at their lower ends. Each roller includes a wheel seat and a wheel body rotatably connected to the wheel seat. The wheel seat is rotatably connected to the support leg about a rotation center line, which extends parallel to or collinear with the axis of the support leg. In the folded state, the roller has at least a first position and a second position. In the first position, the roller body is housed between the support legs. In the second position, the roller body is located outside the support leg, and when the foldable tent is tilted to the ground, the roller body can support the ground and roll on the ground.

[0007] The disclosed foldable tent has at least two supporting legs rotatably equipped with wheels, and when the tent frame is in the folded state, the wheels have at least two different positions. In the first position, the wheels are accommodated between multiple supporting legs, and the wheels do not increase the space occupied by the tent frame or affect its shape, thus facilitating tent storage. In the second position, the wheels are located outside the supporting legs, and by tilting the tent, the wheels can support the ground and roll on the ground, allowing the user to move the tent.

[0008] In some embodiments, a locking mechanism is provided between the support leg and the wheel seat to lock the roller in the first position and the second position. An unlocking member is provided on the wheel seat, which can be disposed relatively away from or close to the wheel seat. The unlocking member is configured to disengage the locking mechanism when relatively close to the wheel seat. During use, the user can release the locking mechanism by simply pressing the unlocking member, thereby allowing the roller to change its position.

[0009] In some embodiments, the lower part of the support leg has a hollow cavity, and the locking mechanism includes a locking member movably disposed within the hollow cavity, a first locking hole disposed on the side wall of the support leg, and a second locking hole disposed on the wheel seat, the first locking hole communicating with the hollow cavity; the locking mechanism further includes an elastic member for providing the force required for the locking member to extend out of the hollow cavity from the first locking hole; when the roller is in the first position and the second position, the first locking hole and the second locking hole are interconnected, the locking member is inserted into the first locking hole and simultaneously inserted into the second locking hole, and the locking mechanism is in a locked state; when the locking mechanism is in an unlocked state, the locking member retracts from the second locking hole; the unlocking member is configured to drive the locking member out of the second locking hole when relatively close to the wheel seat. When the roller is in the first position or the second position, the locking mechanism can automatically switch and remain in the locked state under the actuation of the elastic member.

[0010] In some embodiments, the locking mechanism includes a locking member movably disposed on the wheel seat or the support leg, the locking member being movably disposed between a locked position and an unlocked position; when in the locked position, the wheel seat and the support leg are locked to each other; when in the unlocked position, the wheel seat is rotatable relative to the support leg; the locking mechanism includes an elastic member for providing the force required to drive the locking member to the locked position; the unlocking member is configured to drive the locking member to the unlocked position when relatively close to the wheel seat.

[0011] In some embodiments, the locking mechanism includes a first locking hole on the support leg and a second locking hole on the wheel seat; when the roller is in the first position and the second position, the first locking hole and the second locking hole are in communication with each other; when the locking member is in the locked position, the locking member is inserted into both the first and second locking holes; when the locking member is in the unlocked position, the locking member is disengaged from the second locking hole; the unlocking member is configured to drive the locking member out of the second locking hole when relatively close to the wheel seat.

[0012] In some embodiments, the lower part of the support leg has a hollow cavity, the locking member is movably disposed in the hollow cavity, the first locking hole is disposed on the side wall of the support leg and communicates with the hollow cavity; the elastic member is used to provide the force required for the locking member to extend out of the hollow cavity from the first locking hole.

[0013] In some embodiments, the unlocking member has a connecting portion and a pressing portion disposed on opposite sides of itself. The connecting portion is rotatably connected to the wheel seat, and the pressing portion is positioned against the second lock hole. Specifically, the pressing portion is positioned against one side of the second lock hole and is movable towards the second lock hole. When the locking mechanism is in the locked state, the locking member is in the locked position, and the locking member abuts against the pressing portion. Driving the pressing portion towards the second lock hole can drive the locking member into the hollow cavity, thereby achieving unlocking.

[0014] In some embodiments, the support leg is provided with two first locking holes, and the wheel seat is provided with two corresponding second locking holes. When the roller is in the first position and the second position, the two first locking holes are respectively connected to the two second locking holes. The elastic element is a V-shaped spring sheet, and the two free ends of the spring sheet are fixed with outwardly protruding protrusions, which constitute the locking element. The two protrusions are respectively inserted into the two first locking holes. The two locking elements make the locking between the wheel seat and the support leg more secure. Pressing the two unlocking elements at the same time can release the locking mechanism, which is simple to operate.

[0015] In some embodiments, the tent frame includes four support legs, with rollers mounted on two adjacent support legs. A limiting mechanism is provided between the rollers and the support legs, configured to prevent the rollers from rotating between the two support legs on which the rollers are mounted. The limiting mechanism includes a guide member disposed on one of the wheel seat and the support leg, and a limiting member disposed on the other. When the rollers are in the first position and the second position, the limiting member blocks one side of the guide member. By limiting the rotation direction of the rollers, the limiting mechanism can prevent the two rollers from interfering with each other during transitions.

[0016] In some embodiments, the wheel seat is sleeved on the support leg, the outer side wall of the support leg is provided with an outwardly protruding limiting member, and the wheel seat is provided with an arc-shaped guide groove extending circumferentially, the arc-shaped guide groove constituting the guide member, and the limiting member is inserted in the arc-shaped guide groove; when the roller is in the first position and the second position, the limiting member abuts against the side wall of the arc-shaped guide groove. The guide groove not only provides guidance for the relative rotation of the wheel seat and the support leg, but also restricts the direction of rotation.

[0017] In some embodiments, the support legs are provided with feet for supporting the ground. When the foldable tent is in the folded state, adjacent feet abut or connect with each other, and an accommodating space is formed between the upper parts of all the feet and all the support legs. When the rollers are in the first position, the wheels are housed in the accommodating space. The interaction between the feet maintains the stability between the support legs and prevents relative displacement of the support legs. This ensures that the tent frame remains stable when the foldable tent is moved using the rollers, while the accommodating space prevents interference between the rollers and other components.

[0018] In some embodiments, one of two adjacent legs has a laterally protruding positioning protrusion, and the other leg has a positioning groove. When the foldable tent is in the folded state, the positioning protrusion is inserted into the positioning groove. The legs abut against each other through the cooperation between the positioning protrusion and the positioning groove.

[0019] In some embodiments, the foldable tent further includes a protective cover for covering the top of the foldable tent when it is in a folded state. The protective cover extends partially downward from the top of the foldable tent, and when the rollers are in the second position, the rollers are outside the protective cover. The protective cover helps maintain the folded state of the tent frame.

[0020] Another aspect of this disclosure is to provide a foldable tent, including a tent body having a folded state and an unfolded state. The tent body includes at least three support legs and a foldable telescopic unit connected between the support legs. In the unfolded state, the multiple support legs are far apart from each other, and the telescopic unit is unfolded. In the folded state, the multiple support legs are close together, and the telescopic unit is folded between the multiple support legs. Each support leg is provided with a support portion. When the tent body is in the folded state, the support portions abut against each other, and at least two support portions are connected to each other. The support portions are used to fix the multiple support legs and prevent relative displacement between the support legs.

[0021] The disclosed foldable tent, when the main body of the tent is in a folded state, achieves mutual fixation between the support legs through the mutual cooperation between the support parts on each support leg, preventing mutual displacement between the support legs, avoiding deformation of the main body of the tent during transportation, and preventing squeezing or collision between the components of the foldable tent.

[0022] In some embodiments, the support legs are provided with wheel assemblies, each wheel assembly including a wheel seat disposed on the support leg and a wheel body rotatably disposed on the wheel seat. In the folded state, the wheel body can be located outside the support leg. When the foldable tent is tilted to the ground, the wheel body can support the ground and roll on the ground, facilitating the movement of the tent. Preferably, at least two support legs are provided with the wheel assemblies, and the support portions disposed on the support legs having the wheel assemblies are fixedly connected to each other. The fixed connection of the support portions prevents the tent body from deforming when the foldable tent is moved using the wheel assemblies. In some embodiments, an accommodating space is formed between the upper part of the support portion and the support leg. The wheel seat is rotatably connected to the support leg. When the tent body is in the folded state, the wheel assembly has a first position and a second position. When the wheel assembly is in the first position, the wheel body is housed within the accommodating space; when the wheel assembly is in the second position, the wheel body is located outside the support leg.

[0023] In some embodiments, the lower end of the support leg is provided with a foot for supporting the ground, and a portion of the foot extends laterally to form the support portion. In some embodiments, the tent body includes four support legs, the support portions on two adjacent support legs abut against each other, and two adjacent support portions are fixedly connected.

[0024] In some embodiments, one of two adjacent support portions has a laterally protruding positioning protrusion, and the other support portion has a positioning groove. When the foldable tent is in a folded state, the positioning protrusion is inserted into the positioning groove. The mutual abutment of the support portions is achieved through the cooperation of the positioning protrusion and the positioning groove. In some embodiments, one of two adjacent support portions has a first connecting hole, and the other support portion has a second connecting hole. The foldable tent also includes a connector. When the tent body is in a folded state, the first connecting hole and the second connecting hole are interconnected. The connector is inserted into both the first and second connecting holes, thereby connecting the two support portions.

[0025] In some embodiments, one of the two adjacent support portions is provided with a first connecting ring, and the other support portion is provided with a second connecting ring. The first connecting ring has a first connecting hole extending along a first direction, and the first connecting ring has two holes spaced apart along the first direction. The second connecting ring has a second connecting hole extending along the first direction. When the tent body is in the folded state, the second connecting ring is inserted between the two first connecting rings, and the connector is inserted into the first connecting ring and the second connecting ring along the first direction. Preferably, the first direction is perpendicular to the axis of the support leg, making the connection between the two support portions less susceptible to external forces, thereby improving the stability of the connection and facilitating disassembly.

[0026] In some embodiments, the support portion is disposed at the lower part of the support leg, and the foldable tent further includes a protective cover for covering the top of the foldable tent when the tent body is in a folded state. The protective cover extends partially downward from the top of the foldable tent. The protective cover and the support portion together maintain the folded state of the tent body.

[0027] In some embodiments, the tent body includes four support legs, the support portions are L-shaped, and when the tent body is in the folded state, the outer sides of the four support portions are smoothly connected; the projected outline of the four support portions on the horizontal plane is rectangular.

[0053] The technical solutions of the embodiments of this disclosure will now be clearly and completely described with reference to the accompanying drawings, so that the advantages and features of this disclosure can be more easily understood by those skilled in the art. Obviously, the embodiments described in this disclosure are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0054] The following are marked in Figures A1-A12: 100, tent frame; 110, telescopic unit; 1, support leg; 10, hollow cavity; 11, first locking hole; 12, limiting component; 13, support foot; 131, positioning protrusion; 132, first connecting ring; 133, second connecting ring; 134, connector; 2, roller; 21, wheel seat; 211, second locking hole; 212, arc-shaped guide groove; 22, wheel body; 3, locking component; 4, elastic component; 5, unlocking component; 50, pivot; 51, connecting part; 52, pressing part; 53, protrusion.

[0055] Referring to Figure A1, Embodiment 1 of this disclosure provides a foldable tent, which includes a tent frame 100 having an unfolded state and a folded state. The tent frame 100 includes at least three support legs 1 and a foldable telescopic unit 110 connected between the support legs 1. When the tent frame 100 is in the folded state, the multiple support legs 1 are close together, and the telescopic unit 110 is folded between the multiple support legs 1.

[0056] At least two support legs 1 have rollers 2 at their lower ends. Each roller 2 includes a wheel seat 21 and a wheel body 22 rotatably connected to the wheel seat 21. The wheel seat 21 is rotatably connected to the support leg 1 about a rotation center line, which extends parallel to or collinear with the axis of the support leg 1. When the tent frame 100 is in a folded state, the rollers 2 have at least a first position and a second position, as shown in Figures A2 and A4. In the first position, the wheel body 22 is housed among the support legs 1, facilitating tent storage. As shown in Figure A5, in the second position, the wheel body 22 is located outside the support leg 1. In this state, when the foldable tent is tilted to the ground, the wheel body 22 can support itself on the ground and roll on the ground. Thus, there is no need to prepare a wheeled transport bag or spend effort loading the foldable tent into a transport bag; the foldable tent can be transferred directly using the rollers 2 on the support legs 1, providing convenience for the user.

[0057] In this embodiment, a locking mechanism is provided between the support leg 1 and the wheel seat 21 to lock the roller 2 in a first position or a second position. In this embodiment, the wheel seat 21 is provided with an unlocking member 5, which can be positioned relatively away from or close to the wheel seat 21. When the unlocking member 5 is relatively close to the wheel seat 21, it can drive the locking mechanism to switch to an unlocked state. During use, the user can release the lock on the roller 2 by pressing the unlocking member 5, thereby allowing the roller 2 to be adjusted between the first and second positions.

[0058] In this embodiment, the locking mechanism includes a locking member 3 movably disposed on the support leg 1 or the wheel seat 21. The locking member 3 is movably disposed between a locked position and an unlocked position. When in the locked position, the locking mechanism is in a locked state, and the wheel seat 21 and the support leg 1 are locked together. When the locking member 3 is in the unlocked position, the locking mechanism is in an unlocked state, and the wheel seat 21 can rotate relative to the support leg 1. In this embodiment, the locking mechanism includes an elastic member 4, which provides the force required to drive the locking member 3 to the locked position, so as to maintain the wheel 2 when it is in the first position or the second position. In this embodiment, the unlocking member 5 is configured to drive the locking member 3 to the unlocked position when it is relatively close to the wheel seat 21. In this embodiment, the locking mechanism further includes a first locking hole 11 disposed on the side wall of the support leg 1 and a second locking hole 211 disposed on the wheel seat 21. When the roller 2 is in the first position and the second position, the first locking hole 11 and the second locking hole 211 are interconnected. When the locking member is in the locked position, the locking member 3 is inserted into both the first locking hole 11 and the second locking hole 211, and the locking mechanism is in a locked state. When the locking member is in the unlocked position, the locking mechanism is in an unlocked state, the locking member 3 exits from the second locking hole 211, and the wheel seat 21 can rotate relative to the support leg 1. In this embodiment, when the unlocking member 5 is relatively close to the support leg 1, it can drive the locking member 3 to exit the second locking hole 211, thereby releasing the locking mechanism. In this embodiment, referring to Figure A10, the lower part of the support leg 1 has a hollow cavity 10, the locking member 3 is movably disposed in the hollow cavity 10, and the first locking hole 11 communicates with the hollow cavity 10.

[0059] In this embodiment, the elastic element 4 provides the force required for the locking element 3 to extend from the first locking hole 11 into the hollow cavity 10. When the roller 2 is switched to the first position or the second position, under the action of the elastic element 4, the locking element 3 automatically extends out of the first locking hole 11 and inserts into the second locking hole 211, so that the locking mechanism automatically switches to the locked state. At the same time, under the action of the elastic element 4, the locking mechanism can maintain the locked state.

[0060] In this embodiment, referring to Figures A3 and A7, the unlocking member 5 has a connecting portion 51 and a pressing portion 52 located on opposite sides of itself. The connecting portion 51 is rotatably connected to the wheel seat 21, and the pressing portion 52 is abutted against the second lock hole 211. Specifically, the pressing portion 52 is abutted against one side of the second lock hole 211 and can move towards the second lock hole 211. In this embodiment, when the locking mechanism is in the locked state, the locking member 3 abuts against the pressing portion 52. Specifically, referring to Figure A8, the connecting portion 51 is located above the pressing portion 52, and the connecting portion 51 is rotatably connected to the wheel seat 21 via a rotating shaft 50. The axis of the rotating shaft 50 extends perpendicularly to the axial direction of the support leg 1. Referring to Figure A10, the pressing portion 52 has a protrusion 53 extending towards the second lock hole 211 on the side near the wheel seat 21. When the locking mechanism is in the locked state, the protrusion 53 abuts against the locking member 3. Referring to Figure A11, by driving the pressing part 52 to move closer to the wheel seat 21, the protrusion 53 also moves closer to the second locking hole 211 and pushes the locking member 3 into the hollow cavity 10, so that the locking member 3 disengages from the second locking hole 211.

[0061] In this embodiment, referring to Figures A6 and A7, the wheel seat 21 is fitted onto the support leg 1. The support leg 1 has two first locking holes 11, and the wheel seat 21 has two corresponding second locking holes 211. Specifically, the two first locking holes 11 are arranged opposite each other along a straight line, and the two second locking holes 211 are also arranged opposite each other along a straight line. When the roller 2 is in the first position and the second position, the two first locking holes 11 are respectively connected to the two second locking holes 211. When switching from the first position to the second position, the second locking hole 211 corresponding to any one of the first locking holes 11 is different. Specifically, the second locking holes 211 corresponding to the first locking hole 11 are swapped. In this embodiment, referring to Figures A9 and A10, the elastic element 4 is a V-shaped spring sheet. The two free ends of the spring sheet are fixed with outwardly protruding protrusions, which constitute the locking element 3. The two protrusions are respectively inserted into the two first locking holes 11. When the roller 2 is in the first and second positions, driven by the outward opening force of the two free ends of the spring, the two protrusions extend out of the first locking hole 11 and into the second locking hole 211. The two locking elements 3 make the locking between the wheel seat 21 and the support leg 1 more secure.

[0062] In this embodiment, each wheel seat 21 is provided with two unlocking parts 5. Pressing the two unlocking parts 5 at the same time causes the two free ends of the spring to come closer together, thereby causing the two protrusions to exit the two second lock holes 211 respectively, thus unlocking the device. The unlocking operation is simple.

[0063] In this embodiment, the tent frame 100 includes four support legs 1. Two adjacent support legs 1 are equipped with rollers 2, while the other two support legs 1 are not equipped with rollers 2. A limiting mechanism is provided between the rollers 2 and the support legs 1. The limiting mechanism is used to restrict the rotation direction of the rollers 2. Specifically, the limiting mechanism is used to prevent the rollers 2 from rotating between the two support legs 1 on which the rollers 2 are provided, thereby avoiding mutual interference between the two rollers 2. The limiting mechanism includes a guide member provided on one of the wheel seat 21 and the support leg 1, and a limiting member 12 provided on the other one. When the rollers 2 are in the first position and the second position, the limiting member 12 abuts against one side of the guide member, thereby restricting the relative movement direction of the two.

[0064] In this embodiment, referring to Figure A3, the limiting member 12 protrudes outward from the outer side wall of the support leg 1. The wheel seat 21 is provided with an arc-shaped guide groove 212 extending circumferentially. The arc-shaped guide groove 212 constitutes the aforementioned guide member, and the limiting member 12 is inserted into the arc-shaped guide groove 212. The cooperation between the arc-shaped guide groove 212 and the limiting member 12 provides guidance for the rotation of the wheel seat 21. At the same time, when the roller 2 is in the first position and the second position, the limiting member 12 abuts against the side wall of the arc-shaped guide groove 212, restricting the displacement of the wheel seat 21 relative to the support leg 1.

[0065] In this embodiment, each support leg 1 is provided with a foot 13 for supporting the ground. When the foldable tent is in the folded state, adjacent feet 13 abut against or connect with each other. The feet 13 fix the support legs 1 together, preventing relative displacement between them, thereby maintaining the shape of the tent frame 100 and preventing deformation of the foldable tent. Thus, when the roller 2 is in the second position, the foldable tent can move stably. Referring to Figure A2, a receiving space is formed between all the feet 13 and all the support legs 1. When the roller 2 is in the first position, the wheel 22 is housed in the receiving space, which can prevent the wheel 22 from interfering with the support legs 1 or the telescopic unit 110.

[0066] In this embodiment, as shown in Figure A12, one of two adjacent legs 13 has a laterally protruding positioning protrusion 131, and the other leg 13 has a positioning groove. When the foldable tent is in the folded state, the positioning protrusion 131 is inserted into the positioning groove, and the two legs 13 abut against each other through the positioning protrusion 131 and the positioning groove. In this embodiment, two adjacent legs 13 are connected together by a connector 134. Specifically, as shown in Figure A12, one leg 13 has a first connecting ring 132, and the other leg 13 has a second connecting ring 133. When the tent frame 100 is in the folded state, the connector 134 is inserted into the first connecting ring 132 and the second connecting ring 133, thereby connecting the two legs 13. When the foldable tent needs to be unfolded, the connector 134 must first be detached from the first connecting ring 132 and the second connecting ring 133. By connecting the two legs 13 with the connector 134, the stability of the contact between the legs 13 can be further improved, the overall integrity of the legs 13 can be improved, and thus the stability of the support legs 1 can be improved.

[0067] In this embodiment, the foldable tent also includes a protective cover (not shown in the figure), which is used to cover the top of the foldable tent when it is in the folded state. The protective cover extends partially downward from the top of the foldable tent, and when the rollers 2 are in the second position, the wheels 22 are outside the protective cover. The protective cover can fix the foldable tent. By covering the top of the foldable tent, it can prevent the foldable tent from unfolding outward. At the same time, with the mutual abutment of the legs 13, the foldable tent can stably maintain its shape and prevent deformation. At the same time, the protective cover does not affect the rolling of the wheels 22. The rollers 2 can be used to transfer the tent. Compared with a wheeled transport bag, the protective cover occupies less space and is easier to carry. In other embodiments, in the folded state, the tent frame 100 is fixed by other fixing structures or methods in the prior art, such as straps, so that the tent frame 100 is kept in the folded state and does not affect the movement of the rollers 2.

[0068] Referring to Figure A1, in this embodiment of the foldable tent, when the tent frame 100 is in the folded state and the casters 2 are in the first position, the tent frame 100 has a regular shape and is approximately rectangular. Even when the protective cover is placed on the tent frame 100, it does not increase the volume of the tent frame 100, nor does it affect the shape of the tent frame 100, making it easy to store. Preferably, a connecting structure is provided between the protective cover and the tent frame 100 for fixing the protective cover and the tent frame 100 together after the protective cover is placed over the foldable tent. In some preferred embodiments, the protective cover is also provided with a handle, which the user can use to move the foldable tent.

[0069] In summary, the foldable tent of this embodiment has rollers 2 on its two support legs 1. When the tent frame 100 is in the folded state, the rollers 2 can be switched to a second position, so that the wheel body 22 is fixed on the outside of the support leg 1. At this time, the tent frame 100 is tilted, and the wheel body 22 can roll on the ground, so that the user can drive the foldable tent to move. In the folded state, the protective cover is placed on the tent frame 100 to fix the tent frame 100 and prevent the tent frame 100 from unfolding. At the same time, the legs 13 can fix the four support legs 1 by abutting and connecting with each other. Under the combined action of the protective cover and the legs 13, the tent frame 100 can be stably maintained in the folded state, so that the foldable tent can also maintain stability when the user moves the foldable tent using the rollers 2. By pressing the two unlocking pieces 5 at the same time, the locking mechanism can be released, and the wheel seat 21 can be driven to rotate around the axis of the support leg 1, so that the roller 2 can be switched to the first position. When in the first position, the locking mechanism automatically switches to the locked state. At this time, the wheel 22 is housed in the space between the upper part of the support leg 13 and the support leg 1. The tent frame 100 has a regular shape and occupies little space, making it easy to store.

[0070] The foldable tent of Embodiment 2 of this disclosure will now be described with reference to Figures B1-B11. Unless otherwise specified, the accompanying drawings in this section are used for illustration with reference to one or more of Figures B1-B11.

[0072] Referring to Figure B1, Embodiment 2 of this disclosure provides a foldable tent, including a tent body 100 having a folded state and an unfolded state. The tent body 100 includes a foldable telescopic unit 120 and at least three support legs 110, with the telescopic unit 120 connected between the support legs. When the tent body 100 is in the unfolded state, the multiple support legs 110 are spaced apart, and the telescopic unit is unfolded. When the tent body 100 is in the folded state, the multiple support legs 110 are close together, and the telescopic unit 120 is folded between the multiple support legs 110.

[0073] Each support leg 110 is provided with a support part 200. When the tent body 100 is in a folded state, each support part 200 directly or indirectly abuts against each other, and at least two support parts 200 are connected to each other. Specifically, at least two support parts 200 are fixedly connected. Through the mutual cooperation between each support part 200, the multiple support legs 110 can be fixed to each other, thereby preventing relative displacement between the support legs 110 and ensuring that the tent body 100 will not deform during transportation.

[0074] In this embodiment, the tent body 100 includes four support legs 110. When the tent body 100 is folded, the four support legs 110 are close together and distributed at the four vertices of a rectangle. In some preferred embodiments, the support portion 200 on each support leg 110 extends to the two adjacent support legs 110, and the two extension directions are perpendicular to each other. In this embodiment, the support portion 200 is L-shaped. When the tent body 100 is folded, the outer sides of the four support portions 200 are smoothly connected, and the projected outline of the four support portions 200 on the horizontal plane is rectangular. Thus, the folded tent body 100 can maintain a cuboid shape, which is regular in shape and easy to store and organize.

[0075] In this embodiment, the support portion 200 is disposed at the lower part of the support leg 110. Specifically, the lower end of the support leg 110 is provided with a foot 300 for supporting the ground. A portion of the foot 300 extends laterally to form the aforementioned support portion 200. The support portions 200 on two adjacent support legs 110 abut against each other or connect with each other. Referring to Figures B2 and B3, the two sides of the foot 300 extend toward the two adjacent support legs 110 respectively, thereby forming an L-shaped support portion 200. When the tent body 100 is in the folded state, the outer contours of all the feet 300 and the support portions 200 are square. In this embodiment, one of the two adjacent support portions 200 is provided with a laterally protruding positioning protrusion 210, and the other support portion 200 is provided with a positioning groove 220. When the foldable tent is in the folded state, the positioning protrusion 210 is inserted into the positioning groove 220. Through the cooperation between the positioning protrusion 210 and the positioning groove 220, the two adjacent support portions 200 abut against each other and connect with each other.

[0076] In this embodiment, one of the two adjacent support portions 200 is provided with a first connecting hole, and the other support portion 200 is provided with a second connecting hole. The foldable tent also includes a connector 400. When the tent body 100 is in a folded state, the first connecting hole and the second connecting hole are interconnected, and the connector 400 is inserted into both the first and second connecting holes, thereby connecting the two support portions 200. Specifically, when the tent body 100 is in a folded state, the first connecting hole and the second connecting hole are interconnected along a first direction, and the connector 400 is inserted into both the first and second connecting holes along the first direction. The first direction is perpendicular to the extension direction of the support leg 110, improving the stability of the connection between the two support portions 200.

[0077] In this embodiment, one of the support portions 200 has a first connecting ring 230 on one side. The first connecting ring 230 has a first connecting hole extending along a first direction, and there are two first connecting rings 230 spaced apart along the first direction. The other support portion 200 adjacent to the support portion 200 with the first connecting ring 230 has a second connecting ring 240, which has a second connecting hole extending along the first direction. When the tent body 100 is in a folded state, the second connecting ring 240 is inserted between the two first connecting rings 230, making the two first connecting holes and the second connecting hole interconnected. The connector 400 is inserted into the first connecting ring 230 and the second connecting ring 240. Through the cooperation between the first connecting ring 230, the second connecting ring 240, and the connector 400, the relative displacement of the two support portions 200 is restricted, achieving mutual fixation of the two support portions 200. After the connector 400 is pulled out from the first connecting hole and the second connecting hole, the connection between the two support portions 200 can be released. In other embodiments, at least two support portions 200 are detachably connected via a snap-fit ​​structure, whereby the connection between the support portions 200 can be easily severed through a simple operation. In still other embodiments, at least two support portions 200 are connected using other existing structures that enable detachable connection for easy disassembly.

[0078] In this embodiment, the foldable tent also includes a protective cover (not shown in the figure). The protective cover covers the top of the foldable tent when the tent body 100 is in the folded state, and extends partially downward from the top of the foldable tent. The protective cover serves to secure the foldable tent, preventing the tent body 100 from unfolding outward. Simultaneously, with the combined action of the protective cover and the support 200, the foldable tent can stably maintain its shape, preventing deformation and thus avoiding collisions and compression between components during transportation. In other embodiments, in the folded state, the tent body 100 is secured using other existing fixing structures or methods, such as straps, which, combined with the support 200, maintain the tent body 100 in the folded state.

[0079] In some embodiments, a wheel assembly 500 is provided on the support leg 110. The wheel assembly 500 includes a wheel seat 510 and a wheel body 520, wherein the wheel seat 510 is disposed on the support leg 110, and the wheel body 520 is rotatably connected to the wheel seat 510. When the tent body is in a folded state, the wheel body 520 is located on the outside of the support leg 110. By driving the foldable tent to tilt on the ground, the wheel body 520 can support the ground and roll on the ground, so that the user can use the wheel assembly 500 to drive the foldable tent to move. In this way, there is no need to prepare a transport bag with wheels, nor is it necessary to spend effort to pack the foldable tent into a transport bag. The foldable tent can be transferred directly using the wheel assembly 500 on the support leg 110, providing convenience for the user.

[0080] In this embodiment, at least two support legs 110 are equipped with wheel assemblies 500. The support portions 200 on the support legs 110 with wheel assemblies 500 are fixedly connected to each other to prevent relative displacement between the support legs 110 with wheel assemblies 500 during the movement of the foldable tent. This maintains the stability between the wheel assemblies 500 and improves the stability of the foldable tent, ensuring its normal transfer. In this embodiment, the foldable tent has a total of four support legs 110, of which two adjacent support legs 110 are equipped with wheel assemblies 500. The two support legs 110 with wheel assemblies 500 are located on the same side. In the folded state, the support portions 200 of the two support legs 110 with wheel assemblies 500 are fixedly connected together.

[0081] In this embodiment, the wheel seat 510 is rotatably connected to the lower end of the support leg 110. Specifically, the wheel seat 510 is sleeved on the support leg 110 and can rotate around the support leg 110. When the tent body 100 is in a folded state, the wheel assembly 500 has at least a first position and a second position, as shown in Figures B2 and B4. When the wheel assembly 500 is in the first position, it is stored between the multiple support legs 110, facilitating the folding and organization of the tent. When the wheel assembly 500 is in the second position, it extends to the outside of the support leg 110, allowing the tent to be moved.

[0082] In this embodiment, a locking mechanism is provided between the support leg 110 and the wheel seat 510 to lock the wheel assembly 500 in a first position and a second position. In this embodiment, the wheel seat 510 is provided with an unlocking member 600, which can be positioned relatively away from or close to the wheel seat 510. When the unlocking member 600 is relatively close to the wheel seat 510, it can drive the locking mechanism to release the lock. Specifically, during use, the user can release the lock of the wheel assembly 500 by pressing the unlocking member 600, thereby driving the wheel assembly 500 to adjust between the first position and the second position.

[0083] In this embodiment, the locking structure includes a locking member 700 movably disposed on the support leg 110 or the wheel seat 510, a first locking hole 111 disposed on the side wall of the support leg 110, and a second locking hole 511 disposed on the wheel seat 510. When the wheel assembly 500 is in the first position and the second position, the first locking hole 111 and the second locking hole 511 are interconnected, and the locking member 700 is inserted into both the first and second locking holes 111, and the locking mechanism is in a locked state. When the locking mechanism is in an unlocked state, the locking member 700 is disengaged from the second locking hole 511, and the wheel seat 510 can rotate relative to the support leg 110. Specifically, referring to Figure B10, the lower part of the support leg 110 has a hollow cavity 113, and the locking member 700 is movably disposed in the hollow cavity 113, with the first locking hole 111 communicating with the hollow cavity 113. In this embodiment, the locking mechanism further includes an elastic element 800, which provides a force for the locking member 700 to extend from the first locking hole 111 into the hollow cavity 113. When the wheel assembly 500 is switched to the first position or the second position, under the action of the elastic element 800, the locking member 700 automatically extends out of the first locking hole 111 and inserts into the second locking hole 511, so that the locking mechanism automatically switches to the locked state. At the same time, under the action of the elastic element 800, the locking mechanism can maintain the locked state.

[0084] In this embodiment, when the unlocking member 600 is relatively close to the support leg 110, it can drive the locking member 700 out of the second lock hole 511, thereby releasing the locking mechanism. In this embodiment, referring to Figures B5 and B8, the unlocking member 600 has a connecting portion 610 and a pressing portion 620 located on opposite sides of itself. The connecting portion 610 is rotatably connected to the wheel seat 510, and the pressing portion 620 is positioned on one side of the second lock hole 511. Specifically, referring to Figure B8, the connecting portion 610 is located above the pressing portion 620, and the connecting portion 610 is rotatably connected to the wheel seat 510 via a rotating shaft 601. The axis of the rotating shaft 601 extends perpendicularly to the axial direction of the support leg 110. Referring to Figure B10, the pressing portion 620 has a protrusion 630 extending into the second lock hole 511 on the side near the wheel seat 510. When the locking mechanism is in the locked state, the protrusion 630 abuts against the locking member 700. Referring to Figure B11, by driving the pressing part 620 to move closer to the wheel seat 510, the protrusion 630 also moves closer to the second locking hole 511 and pushes the locking member 700 into the hollow cavity 113, so that the locking member 700 disengages from the second locking hole 511.

[0085] In this embodiment, referring to Figures B6 and B7, the support leg 110 is provided with two first locking holes 111, and the wheel seat 510 is provided with two corresponding second locking holes 511. Specifically, the two first locking holes 111 are arranged opposite each other along a straight line, and the two second locking holes 511 are also arranged opposite each other along a straight line. When the wheel assembly 500 is in the first position and the second position, the two first locking holes 111 are respectively connected to the two second locking holes 511, and when the wheel assembly 500 is switched from the first position to the second position, the second locking holes 511 corresponding to the first locking holes 111 are swapped. In this embodiment, referring to Figure B9, the elastic element 800 is a V-shaped spring sheet, and the two free ends of the spring sheet are fixed with outwardly protruding protrusions, which constitute the locking element 700. The two protrusions are respectively inserted into the two first locking holes 111. When the wheel assembly 500 is in the first and second positions, driven by the outward opening force of the two free ends of the spring, the two protrusions extend out of the first locking hole 111 and into the second locking hole 511. The provision of two locking elements 700 makes the locking between the wheel seat 510 and the support leg 110 more secure.

[0086] In this embodiment, each wheel seat 510 is provided with two unlocking parts 600. Pressing the two unlocking parts 600 at the same time causes the two free ends of the spring to come closer together, thereby causing the two protrusions to exit the two second lock holes 511 respectively, thus achieving unlocking. The unlocking operation is simple.

[0087] In this embodiment, wheel assemblies 500 are provided on two adjacent support legs 110, while wheel assemblies 500 are not provided on the other two support legs 110. A limiting mechanism is provided between the wheel assembly 500 and the support leg 110. The limiting mechanism is used to restrict the rotation direction of the wheel assembly 500. Specifically, the limiting mechanism is used to prevent the wheel assembly 500 from rotating towards the middle of the two support legs 110 on which the wheel assembly 500 is provided, thereby avoiding mutual interference between the two wheel assemblies 500. The limiting mechanism includes a guide member provided on one of the wheel seat 510 and the support leg 110, and a limiting member 112 provided on the other one. When the wheel assembly 500 is in the first position and the second position, the limiting member 112 abuts against one side of the guide member, thereby restricting the relative movement direction of the two.

[0088] In this embodiment, referring to Figure B5, the limiting member 112 protrudes outward from the outer wall of the support leg 110, and the wheel seat 510 is provided with an arc-shaped guide groove 512 extending circumferentially. The arc-shaped guide groove 512 constitutes the aforementioned guide member, and the limiting member 112 is inserted into the arc-shaped guide groove 512. The cooperation between the arc-shaped guide groove 512 and the limiting member 112 provides guidance for the rotation of the wheel seat 510. At the same time, when the wheel assembly 500 is in the first position and the second position, the limiting member 112 abuts against the side wall of the arc-shaped guide groove 512, restricting the displacement of the wheel seat 510 relative to the support leg 110. In this embodiment, when the tent body 100 is in a folded state, an accommodating space is formed between the upper part of the support 200 and the support leg 110. When the wheel assembly 500 is in the first position, the wheel assembly 500 is stored in the accommodating space, which reduces the volume of the tent body 100 and maintains the regularity of the shape of the tent body 100. It can also prevent the wheel 520 from interfering with the support leg 110 or the telescopic unit 120.

[0089] In summary, in this embodiment of the foldable tent, when the tent body 100 is in a folded state, the support portions 200 on each support leg 110 abut against each other, and the two support portions 200 are connected together by the connector 400, so that each support portion 200 becomes a whole, thereby fixing each support leg 110 to each other, avoiding relative displacement between the support legs 110, thus preventing the foldable tent from deforming, and also preventing squeezing or collision between the components.
