Description

Technical Field

[0001] This utility model relates to the field of tent technology, and in particular to the folding structure of a vehicle tail tent. Background Technology

[0002] Traditional rear tents have a fixed opening size at the outer end, making them only suitable for connecting the rear of SUVs (three-box cars) or sedans (two-box cars). If the rear tent is to be used with the other type of vehicle, a different size rear tent needs to be purchased separately. Traditional rear tents have poor versatility. Utility Model Content

[0003] One objective of this invention is to solve or alleviate the aforementioned technical problems.

[0004] The present invention employs a folding structure for a vehicle rear tent, comprising a tent body and a connecting door tent. The tent body has a connecting portion; the connecting door tent is connected to the tent body such that the connecting portion is completely located within the connecting door tent; it also includes a folding portion connected to the connecting door tent and having a folded state and an unfolded state. When the folding portion is in the folded state, there is a portion of the folding portion overlapping with the connecting door tent, and when the folding portion is configured to be in the unfolded state, the opening size of the connecting door tent is increased.

[0005] The effect achieved by this utility model is that it can increase the perimeter of the opening at the outer end of the connecting door tent, thereby improving the versatility of the connecting door tent.

[0006] A further technical solution is provided where the connecting door tent is provided with a connectable gap that connects to the outside from the outer end of the connecting door tent. The two gaps of the connectable gap are configured to be close to each other so that the folded part is in a folded state or far apart from each other so that the folded part is in an unfolded state.

[0007] A further technical solution is that the folded part unfolds into a triangle or trapezoid, and the two sides of the triangle or trapezoid of the folded part are respectively overlapped and fixed with the two gap edges of the connectable gap.

[0008] A further technical solution involves setting the folding part on the inner wall of the connecting tent, and the inner wall of the connecting tent is provided with straps for securing the folding part.

[0009] This technical solution can fix the folding part inside the connecting door curtain, preventing the folding part from sagging and affecting its use and storage.

[0010] A further technical solution also includes a gap-blocking part that is fixedly connected to the connecting door tent, the part of the gap-blocking part that is fixedly connected to the connecting door tent is a fixing part; the connectable gap is set on the side wall of the connecting door tent, and the fixing part is located above the connectable gap so that the gap-blocking part covers the connectable gap.

[0011] This technical solution can prevent rainwater from entering the folding section or connecting door through the connectable gaps, thus improving the waterproof effect.

[0012] A further technical solution is to provide an adsorption part on the side wall and / or gap blocking part of the connecting door tent, the adsorption part being located on the side of the connectable gap away from the fixing part and causing the gap blocking part to tend to approach the side wall of the connecting door tent.

[0013] This technical solution can further improve the waterproof effect and prevent inconvenience caused by the lifting of the gap cover.

[0014] A further technical solution involves providing an elastic telescopic strap at the outer end of the connecting tent, which causes the opening at the outer end of the connecting tent to tend to narrow; the telescopic strap passes through a folding section.

[0015] This technical solution can ensure the seal between the opening at the outer end of the connecting tent and the rear of the vehicle even when the perimeter of the opening at the outer end of the connecting tent increases.

[0016] A further technical solution is that both edges of the connectable gap are provided with zipper teeth, and zipper heads are provided on the zipper teeth of the two edges of the connectable gap.

[0017] A further technical solution is that the unfolded part is an isosceles triangle or an isosceles trapezoid.

[0018] A further technical solution is to set the connection gap in the same direction as the connection door curtain. Attached Figure Description

Detailed Implementation

[0031] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.

[0032] As a specific embodiment, the vehicle rear tent structure of this utility model includes a tent body 1 and a connecting door tent 2. The tent body 1 is used for the tent user to move around inside, and the connecting door tent 2 is used to connect the tent body 1 to the rear of the vehicle 9, thereby connecting the vehicle 9 and the tent body 1 to form a closed space, which can both expand the area of ​​privacy and allow the cold air generated by the vehicle 9 to enter the vehicle rear tent structure.

[0033] It should be noted that when the vehicle rear tent structure is deployed, it can be connected to the vehicle 9 via the connecting door tent 2, or it can be left unconnected. When the connecting door tent 2 is not connected to the vehicle 9, the vehicle rear tent can function as a regular tent. In this case, the connecting door tent 2 can be stored away, and the storage method is not limited. For example, it can be rolled up and secured using the straps of the tent body 1 (not shown in the attached diagram). Alternatively, the connecting door tent 2 can be detachably connected to the tent body 1, allowing it to be directly removed.

[0034] The tent body 1 is provided with a connecting part 11. In some embodiments, the connecting part 11 is an opening in the tent body 1, through which the connecting door 2 can communicate with the interior of the tent body 1 (not shown in the figure). In other embodiments, the connecting part 11 is an opening in the tent body 1 and a cover (not shown in the figure) provided in the opening. The cover can be detachably connected to the tent body 1, thereby realizing the communication or closure between the connecting door 2 and the tent body 1. The detachable connection method between the cover and the tent body 1 is not limited. For example, it can be detachably connected by a zipper, Velcro, or other structures. The tent body 1 has a bottom wall and at least three sides connected to the bottom wall. The at least three sides are connected in sequence and together with the bottom wall form the tent body 1, wherein at least one of the sides is provided with the connecting part 11.

[0035] Typically, the tent body 1 also includes a tent back door 17, with the connecting part 11 and the tent back door 17 located on the front and rear sides of the tent body 1, respectively; tent side windows 18 are provided on the left and right sides of the tent body 1. The tent body 1 can be a tent that is shaped by being suspended by the tent frame 19 and the tent suspension lines 191 on the tent frame 19, or it can have hooks (not shown in the attached diagram) formed at the tent body 1 to hook onto the tent frame 19 for connection, or it can be a rigid tent (relying on its own rigidity to maintain its shape, without the need for a tent frame 19). Since the tent body 1 is usually made of fabric and can deform, it has open and folded states. The positional relationships described below are all based on the tent body 1 being in the open state and connected to the door tent 2 and the vehicle.

[0036] The connecting tent 2 is connected to the tent body 1 such that the connecting part 11 is completely located within the connecting tent 2. For example, the projection of the connecting part 11 on the vertical plane is completely within the projection of the curve formed by the intersection of the connecting tent 2 and the tent body 1 on the same vertical plane. A water-retaining part 241 is provided at the bottom end of the connecting part 11; the connecting tent 2 has a connecting tent bottom wall 24, the inner end of which is fixedly connected to the top end of the water-retaining part 241, and the connecting tent bottom wall 24 is at least partially lower than the top end of the water-retaining part 241.

[0037] The connecting tent 2 is equipped with an elastic telescopic strap 22 (for example, the telescopic strap 22 is provided at the end of the connecting tent 2 away from the connecting part 11; of course, the telescopic strap 22 can also be provided in the middle of the connecting tent 2, or at a position on the connecting tent 2 with a gap between it and the connecting part 11). The telescopic strap 22 causes the opening at the outer end of the connecting tent 2 to tend to narrow, meaning that the circumference of the opening at the outer end of the connecting tent 2 becomes smaller. In use, the outer end of the connecting tent 2 is fitted over the rear of the vehicle 9. Under the action of the telescopic strap 22, the opening at the outer end of the connecting tent 2 can expand or shrink within a certain range. When connected to the rear of the vehicle 9, the connecting tent 2 can apply a tightening force to the rear of the vehicle 9, thereby making the connecting tent 2 fit tightly against the rear of the vehicle 9 and preventing or reducing rainwater from entering the connecting tent 2 from the opening at the outer end of the connecting tent 2. If the air conditioner of the vehicle 9 is turned on, it can also prevent air leakage from the connecting tent 2 and the tent body 1. Furthermore, for the rear of vehicles 9 of different specifications (typically, the shape and size of the rear of vehicle 9 also change according to the specifications of vehicle 9), the opening at the outer end of the connecting door tent 2 can, under the action of the telescopic strap 22, fit tightly against the rear of vehicle 9 within a certain size range, thus improving versatility. The rear tent structure of this embodiment of the present invention ensures a tight seal between the opening at the outer end of the connecting door tent 2 and the rear of vehicle 9, thereby improving versatility.

[0038] As one specific implementation, the outer ends of the connecting tent 2 are located on the same vertical plane. In other words, the edges of the upper side wall, the left side wall, the right side, and the bottom wall 24 of the connecting tent 2 are all located in the same vertical plane.

[0039] As one specific implementation, the telescopic strap 22 is a closed ring and fixed inside the connecting door tent 2. For example, the telescopic strap 22 is sewn to the inner surface of the outer end of the connecting door tent 2 for fixation; or, for another example, the telescopic strap 22 is fixed between two layers of fabric at the outer end of the connecting door tent 2, that is, the telescopic strap 22 is fixed inside the outer end of the connecting door tent 2. The telescopic strap 22 is a closed ring, meaning that the ends of the telescopic strap 22 are connected to each other, so that the inside and outside of the telescopic strap 22 are completely separated. The closed ring of the telescopic strap 22 allows the contraction force on the opening at the outer end of the connecting door tent 2 to be consistent, so that any position of the opening can be stretched and contracted to accommodate different types of car rear ends 9. The connecting door tent 2 is made of waterproof fabric or the like, and the telescopic strap 22 is placed inside the connecting door tent 2 to prevent it from contacting rainwater, thereby ensuring the service life of the telescopic strap 22.

[0040] As one specific implementation, at least one pair (two in a pair) of quick-locking straps 221 are provided at the outer end of the connecting tent 2. The quick-locking straps 221 are all arranged along the telescopic belt 22. The ends of the two quick-locking straps 221 in a pair are detachably connected to each other. For example, one end of each pair of quick-locking straps 221 (i.e., the other end of the quick-locking strap 221) is fixedly connected to the connecting tent 2. The ends of the two quick-locking straps 221 in a pair are detachably connected via a buckle structure 3. The buckle structure 3 includes a male buckle 31 and a female buckle 32. The male buckle 31 is provided with a long rod 341, and both sides of the long rod 341 are provided with length adjustment holes 34. The female buckle 32 is provided with a connecting hole 33. The ends of the two quick-locking straps 221 in a pair... One end of the quick-locking strap 221 passes sequentially through the length adjustment hole 34, the length rod 341, and the length adjustment hole 34 again before returning to the length adjustment hole 34, so that one end of the pair of quick-locking straps 221 is connected to the male buckle 31, and the position of the male buckle 31 on the quick-locking strap 221 can be adjusted; the other end of the pair of quick-locking straps 221 passes through the connecting hole 33 and is sewn to itself, so that the other end of the pair of quick-locking straps 221 is fixedly connected to the female buckle 32. The male buckle 31 is inserted into the female buckle 32 and fixed to it. Pressing the male buckle 31 allows it to be pulled out of the female buckle 32, thus achieving a detachable connection through the buckle structure 3. It is easy to understand that those skilled in the art will readily conceive of using the buckle structure 3 for the detachable connection described later. Figure 9As shown, after the outer end of the connecting tent 2 is fitted over the rear of the vehicle 9, the ends of the two quick-locking straps 221 are connected to each other, which can quickly lock and fix the opening of the outer end of the connecting tent 2 to the rear wheel well 931. It is easy to understand that the quick-locking straps 221 can only partially reduce the opening of the outer end of the connecting tent 2, while the other part of the opening of the outer end of the connecting tent 2 is still tightly fitted to the rear of the vehicle 9 under the action of the telescopic straps 22. Therefore, this embodiment can also ensure that the opening of the outer end of the connecting tent 2 is tightly fitted to the rear of the vehicle 9.

[0041] A connecting strap 23 is provided at the outer end of the connecting gate tent 2. For example, as one specific implementation method, such as Figure 8 As shown, at least one set of inner connecting straps 231 and outer connecting straps 232 are provided at the outer end of the top wall of the tent 2. Both inner connecting straps 231 and outer connecting straps 232 are arranged in a direction away from the main body of the tent 1. The outer ends of the inner connecting straps 231 and outer connecting straps 232 in the same set are detachably connected, for example, by means of a buckle structure 3. One of the outer ends of the inner connecting straps 231 and outer connecting straps 232 passes around the roof rack 92 and then connects to each other, which can ensure that the outer end of the top wall of the tent 2 is firmly connected to the rear of the vehicle 9 and is not easy to fall off the rear of the vehicle 9.

[0042] As one of the specific implementation methods, such as Figure 9 As shown, a rear wheel stop connecting strap 233 is provided at the outer end of the side wall connecting the canopy 2 (or at a position other than the outer end of the side wall connecting the canopy 2). A hook (not shown in the attached diagram) is fixedly provided at the end of the rear wheel stop connecting strap 233 away from the canopy 2. Each rear wheel stop connecting strap 233 has at least two detachably connected ends, for example, these two detachably connected ends are detachably connected by a snap-fit ​​structure 3. The hook is hung on the rear of the vehicle 9, ensuring a secure connection between the outer end of the side wall connecting the canopy 2 and the rear of the vehicle 9, preventing it from easily falling off. When the hook is not needed, the rear wheel stop connecting strap (233) can be detached using the snap-fit ​​structure 3.

[0043] As one of the specific implementation methods, such as Figure 2 As shown, a vehicle bottom connecting strap 234 is provided at the outer end of the bottom wall of the connecting tent 2 (i.e., the bottom wall 24 of the connecting tent). The vehicle bottom connecting strap 234 extends from the outer end of the bottom wall of the connecting tent 2 away from the main tent 1. The vehicle bottom connecting strap 234 is used to connect to the bottom of the rear of the vehicle 9 (such as the hook of the vehicle 9), which can ensure that the outer end of the bottom wall of the connecting tent 2 is firmly connected to the rear of the vehicle 9 and is not easy to fall off.

[0044] As one of the specific implementation methods, such as Figure 7As shown, the connecting canopy 2 also includes an extension strap 235 with a front cover pivot hook 236 at one end. The other end of the extension strap 235 is detachably connected to the inner connecting strap 231 and / or the outer connecting strap 232, for example, via a snap-fit ​​structure 3. The front cover pivot hook 236 is hung on the front cover pivot 911 of the car hood 91 or other locations on the car 9. The other end of the extension strap 235 wraps around the roof of the car 9 and is detachably connected to the inner connecting strap 231 and / or the outer connecting strap 232, ensuring a secure connection between the outer end of the top wall of the connecting canopy 2 and the rear of the car 9, preventing it from easily detaching. Furthermore, this embodiment also ensures a secure connection between the outer end of the top wall of the connecting canopy 2 and the rear of the car 9 for cars 9 without a roof rack 92, offering high versatility. When connecting the car 9, the inner connecting strap 231 can be connected to the outer connecting strap 232 and used in conjunction with the car 9, or the extension strap 235 can be added as needed, providing high flexibility.

[0045] like Figure 6 As shown, the rear tent structure of this embodiment of the utility model further includes a folding part 21, which is connected to the connecting door tent 2 and has a folded state and an unfolded state. When the folding part 21 is in the folded state, there is a portion of the folding part 21 that overlaps with the connecting door tent 2. When the folding part 21 is configured to be in the unfolded state, the opening size of the connecting door tent 2 is increased. It should be noted that when the folding part 21 has a portion that partially overlaps with the connecting door tent 2, it can be considered that the folding part 21 is in the folded state. When the folding part 21 is in the unfolded state, the surface of the folding part 21 can be substantially on the same outer surface as the connecting door tent 2.

[0046] The connecting door 2 is provided with a connectable gap 211 that connects to the outside from the outer end of the connecting door 2. The two gap edges of the connectable gap 211 (not shown in the attached figure. It is easy to understand that when the two gap edges of the connectable gap 211 are connected to each other, the connectable gap 211 is a line; when the two gap edges of the connectable gap 211 are separated from each other, the connectable gap 211 is divided into two lines, and these two lines are the two gap edges) are detachably connected to each other. For example, both gap edges of the connectable gap 211 are provided with zipper teeth (such as... Figure 6As shown in the grid-like filling, zipper heads (not shown in the attached figure) are provided on the zipper teeth of the two gap edges of the connectable gap 211. The zipper heads move back and forth on the zipper teeth of the two gap edges of the connectable gap 211, so that the two sides of the connectable gap 211 can be separated and connected to each other. Of course, the two gap edges of the connectable gap 211 can also be detachably connected to each other by a snap-fit ​​structure 3, Velcro, or other means. The two ends of the folding part 21 are respectively fixedly connected to the connecting door curtain 2 on both sides of the connectable gap 211, so that the folding part 21 has a part that overlaps with the connecting door curtain 2. In other words, the connecting door curtain 2 is provided with a connectable gap 211 that communicates with the outside from the outer end of the connecting door curtain 2. The two gaps of the connectable gap 211 are configured to be close to each other so that the folding part 21 is in a folded state or far apart so that the folding part 21 is in an unfolded state. In summary, the folding part 21 is connected to the connecting door tent 2 and has a folded state and an unfolded state. When the folding part 21 is in the folded state, there is a portion of the folding part 21 that overlaps with the connecting door tent 2. When the folding part 21 is configured to be in the unfolded state, the opening size of the connecting door tent 2 is increased. Figure 6 As shown, after the two gap edges of the connectable gap 211 are separated from each other, the folding part 21 can be unfolded, thereby expanding the outer opening of the connecting door 2 and increasing the circumference of the outer opening of the connecting door 2, thus improving the versatility of the connecting door 2. For example, for SUVs and other hatchbacks, when the rear size of the car 9 is large, the connecting door 2 with the two gap edges of the connectable gap 211 separated can be used; for sedans and other three-box cars, when the rear size of the car 9 is small, the connecting door 2 with the two gap edges of the connectable gap 211 connected can be used. The setting direction of the connectable gap 211 is the same as the setting direction of the connecting door 2; it should be noted that, as Figure 4 As shown, the connecting door 2 is set in the horizontal direction, and the connectable gap 211 is set at an angle and has a vector in the horizontal direction. Therefore, the setting direction of the connectable gap 211 is the same as the setting direction of the connecting door 2.

[0047] As another implementation, the connectable gaps 211 are not limited to being detachably connected to each other. For example, the connectable gaps 211 can always remain connected. See the following for details. Figure 10 ,like Figure 10As shown by the thick solid line and the rectangle on the thick solid line, there is a folded connection point on each of the two edges of the connectable gap 211. A folded rope is provided between the two folded connection points, and the connectable gap 211 is always connected by the folded rope. A folded rope locking device is provided on the folded rope, and the two middle sections of the folded rope pass through the rope locking device. The rope locking device is a prior art device used to maintain its relative position with the folded rope. After the folded rope is received, adjusting the length of the two middle sections of the folded rope can make the two folded connection points coincide; conversely, it can separate the two folded connection points. It is easy to understand that multiple folded ropes can be provided along the connectable gap 211. The folded rope can be an elastic rope, and the folded rope locking device can be a double-hole rope buckle.

[0048] As one specific implementation, the folding part 21 unfolds into a triangle or trapezoid, and the two sides of the triangle or trapezoid of the folding part 21 overlap and are fixed with the two gap edges of the connectable gap 211. In this implementation, only the perimeter of the outer end opening of the door curtain 2 increases when the folding part 21 is unfolded.

[0049] It should be noted that the folded part 21 can be two pieces of fabric that are different from the connecting door curtain 2 and are connected by sewing. Alternatively, the folded part 21 can be integrally connected to the connecting door curtain 2, which is equivalent to a part of the connecting door curtain 2. In this case, the connection between the folded part 21 and the connecting door curtain 2 can be understood as the connection between the folded part 21 and the non-folded part 21 in the connecting door curtain 2.

[0050] As one specific implementation, the folding part 21 is rectangular when unfolded, and the two opposite sides of the rectangle of the folding part 21 (not the two adjacent sides of the rectangle) overlap and are fixed with the two gap edges of the connectable gap 211. In this implementation, when the folding part 21 is unfolded, the perimeter of the opening at the outer end of the connecting door tent 2 and the perimeter of the middle part of the connecting door tent 2 both increase, thereby expanding the internal space of the connecting door tent 2.

[0051] It should be noted that the shape of the unfolded fold 21 is not limited. In other embodiments, the fold 21 may also be other regular or irregular shapes.

[0052] As one specific embodiment, the folding part 21 is provided on the inner wall of the connecting door curtain 2, and the inner wall of the connecting door curtain 2 is provided with a strap for fixing the folding part 21 (not shown in the figure). This embodiment can fix the folding part 21 inside the connecting door curtain 2, preventing the folding part 21 from sagging and affecting its use and storage.

[0053] As one specific implementation, the rear tent structure of this utility model further includes a gap-covering part 212 fixedly connected to the connecting door tent 2. The part of the gap-covering part 212 fixedly connected to the connecting door tent 2 is a fixing part 213, for example, the gap-covering part 212 is sewn to the outer wall of the connecting door tent 2 to form the fixing part 213. The connectable gap 211 is provided on the side wall of the connecting door tent 2 (i.e., the left side wall and / or right side wall of the connecting door tent 2), and the fixing part 213 is located on one side of the connectable gap 211 so that the gap-covering part 212 covers the connectable gap 211. After rainwater accumulates on the connecting door tent 2, it flows down from the side wall of the connecting door tent 2 due to its own weight. When passing through the gap-covering part 212, it flows down from the outer wall of the gap-covering part 212 without passing through the connectable gap 211, which can prevent rainwater from entering the folding part 21 or the connecting door tent 2 from the connectable gap 211, thereby improving the waterproof effect.

[0054] As one specific implementation, an adsorption part 214 is provided on the side wall and / or gap-blocking part 212 of the connecting door 2. The adsorption part 214 is located on the side of the connectable gap 211 away from the fixing part 213, that is, the adsorption part 214 and the fixing part 213 are located on opposite sides of the connectable gap 211, and the gap-blocking part 212 tends to be close to the side wall of the connecting door 2. For example, the adsorption part 214 is Velcro, a magnet, a disk, etc., which makes the gap-blocking part 212 tend to be close to the side wall of the connecting door 2. This implementation can further prevent rainwater from entering the folding part 21 or the connecting door 2 from the connectable gap 211, improve the waterproof effect, and also prevent inconvenience caused by the gap-blocking part 212 sticking up.

[0055] As one specific implementation, the telescopic strap 22 passes through the fold 21; in other words, when the fold 21 is unfolded, the telescopic strap 22 remains a closed loop. This implementation ensures a tight seal between the opening at the outer end of the connecting door tent 2 and the rear of the vehicle 9, even when the circumference of the opening at the outer end of the connecting door tent 2 increases.

[0056] like Figure 4 As shown, the bottom wall of the connecting door tent 2 is the connecting door tent bottom wall 24, and a drainage hole 242 is provided on the connecting door tent bottom wall 24. Rainwater and other water that leaks into the connecting door tent 2 can be discharged through the drainage hole 242, which can reduce the amount of rainwater and other water in the connecting door tent 2 and enable the connecting door tent 2 to have a drainage function.

[0057] As one specific implementation, a water-blocking part 241 is provided at the bottom end of the connecting part 11; the inner end of the bottom wall 24 of the connecting tent is fixedly connected to the top end of the water-blocking part 241, and the bottom wall 24 of the connecting tent is at least partially lower than the top end of the water-blocking part 241. When rainwater flows into the connecting tent 2 from the gap between the connecting tent 2 and the vehicle 9, it will accumulate towards the bottom wall 24 of the connecting tent under the action of gravity. Since the bottom wall 24 of the connecting tent is at least partially lower than the top end of the water-blocking part 241, the rainwater accumulated on the bottom wall 24 of the connecting tent will be blocked by the water-blocking part 241. This prevents rainwater and other water accumulated on the bottom wall 24 of the connecting tent from entering the tent body 1 through the connecting part 11.

[0058] The water-blocking part 241 can be a lower portion of one side of the tent body 2, and the water-blocking part 241 is integrally connected to the other parts of the corresponding side of the tent body 2. The bottom end of the water-blocking part 241 can be connected to the bottom wall of the tent body 2. In other embodiments, the water-blocking part 241 can also be a structure independent of the tent body 2, as long as it is at least partially located below the connecting part 11, and the top end of the water-blocking part 241 is higher than the bottom wall 24 of the connecting door tent, thereby preventing rainwater from entering the tent body 2.

[0059] like Figure 4 As shown by the thick dashed line, before the connection between the tent flap 2 and the rear of the vehicle 9, the telescopic strap 22 is stretched, making the opening at the outer end of the tent flap 2 larger. At this time, the opening at the outer end of the tent flap 2 is enlarged, and the cross-section of the bottom wall 24 of the tent flap can be an inclined strip. The end of the strip furthest from the tent body 1 is lower than the end closest to the tent body 1, thus making the strip inclined. The lowest point of the bottom wall 24 of the tent flap is higher than the bottom wall of the tent body 1. Figure 4 As shown by the thin dashed lines, the connecting tent 2 is connected to the rear of the car 9, and the telescopic strap 22 reduces the opening at the outer end of the connecting tent 2, resulting in an arc-shaped cross-section of the bottom wall 24 of the connecting tent. Both the inner and outer ends of the bottom wall 24 are higher than the ground. When a user steps on the bottom wall 24, a portion of the bottom wall 24 dips down and contacts the ground. Rainwater accumulated on the bottom wall 24 flows downwards due to its own weight and is discharged outside the bottom wall 24 through the drainage hole 242, improving the drainage effect of the connecting tent 2. Furthermore, when the user leaves the bottom wall 24, the bottom wall 24 returns to its original position, separating the drainage hole 242 from the ground, preventing water from the ground from flowing back into the connecting tent 2. Of course, even if the tent user does not step on the bottom wall 24 of the connecting door tent, the partial concavity of the bottom wall 24 of the connecting door tent can improve the drainage effect of the connecting door tent 2.

[0060] It should be noted that the cross-sectional shape of the connecting bottom wall 24 of the tent is not limited to being changed from a strip-shaped incline to an arc shape by the telescopic belt 22. In other embodiments, the cross-section of the connecting bottom wall 24 of the tent may be either a strip-shaped incline or an arc shape, regardless of whether it is in the expanded or shrunken state.

[0061] As one specific implementation, the top of the water-blocking part 241 extends upward to form an upper extension part 243. This implementation can further prevent rainwater and other water accumulated on the bottom wall 24 of the connecting door from entering the tent body 1 through the connecting part 11, thereby improving the effect of preventing water from entering the tent body 1.

[0062] As one specific implementation method, there are multiple drainage holes 242, which are arranged in a direction perpendicular to the setting direction of the connecting door curtain 2. For example... Figure 4 As shown, the multiple drainage holes 242 are arranged in a direction perpendicular to the paper. The "middle position" can be understood as the drainage hole 242 being approximately located in the middle of the bottom wall 24 of the connecting door tent 2 in the direction it is set up. Furthermore, the drainage hole 242 is also approximately located in the middle of the bottom wall 24 of the connecting door tent 2 in both the horizontal and perpendicular directions. The drainage holes 242 are concentrated in the middle of the connecting door tent 2. Due to the effect of the telescopic belt 22, the bottom wall 24 of the connecting door tent 24, located in the middle, is lower both in the direction perpendicular to and along the direction it is set up, making it easier to drain rainwater.

[0063] As one specific implementation, a metal insert is provided inside the drainage hole 242. For example, the drainage hole 242 is a circular hole, and the metal insert is shaped like a C-shaped cross-section, formed by rotating around the axis located on the left side of the C-shape. The metal insert is respectively attached to the inner wall of the drainage hole 242, the top surface of the connecting tent bottom wall 24 at the outer periphery of the drainage hole 242, and the bottom surface of the connecting tent bottom wall 24 at the outer periphery of the drainage hole 242. This implementation can ensure the strength of the connecting tent bottom wall 24, ensuring that the connecting tent bottom wall 24 will not or is not easily torn from the drainage hole 242 when the tent user passes through the drainage hole 242.

[0064] The terms used in this invention, such as "first," "second," etc., do not indicate any order, quantity, or importance, but are merely for distinction.

[0065] In this invention, terms such as "a" or "an" are used to indicate not a limitation on the quantity, but rather to indicate the existence of at least one of the mentioned objects.

[0066] In this utility model, terms indicating direction or location such as top, bottom, side, longitudinal, transverse, middle, center, outside, inside, horizontal, vertical, left, right, above, and below are used to indicate relative positions rather than absolute positions.

[0067] Terms used in this invention, such as "approximately," "generally," "approximately," and "similar," are limiting terms used to indicate features that are present but allow for certain deviations. The amount of deviation allowed may vary depending on the specific context; for example, regarding dimensional deviations, the specific context may include, but is not limited to, relevant standards for dimensional tolerances.
