Description

Technical Field

[0001] This invention relates to the field of rooftop tent equipment, and in particular to a disassembly structure for a rooftop tent. Background Technology

[0002] A rooftop tent is a two-in-one tent that is fixed to the roof of a truck or car and mounted on the roof rack. It is popular because it can be easily unfolded to provide a relatively safe and comfortable sleeping space for campers. A typical rooftop tent includes a base, ladder, tent fabric, and multiple tent fabric supports. To maximize interior space, most existing rooftop tents have folding bases. However, the addition of a ladder inevitably increases the overall size of the rooftop tent when folded and stored. Furthermore, existing designs for detachable ladders are not ideal, failing to balance stability during use with ease of installation. Summary of the Invention

[0003] To address the aforementioned issues, this invention proposes a detachable structure for a rooftop tent, which solves the problem that traditional detachable ladders for rooftop tents cannot simultaneously ensure connection stability and ease of installation.

[0004] The technical solution adopted in this invention is: a disassembly structure for a rooftop tent, including a base plate and a ladder. The base plate is provided with guide rails, two of which are arranged parallel to each other. The guide rails are provided with guide openings, which are strip-shaped and extend along the length of the guide rails. The ladder is provided with pins on both sides. A slider is slidably connected in the guide opening, and a hook is provided on the slider. The guide rail is provided with a first locking device. When the guide rail and the slider are locked relative to each other by the first locking device, a closed annular area for accommodating the pins is formed between the inner contour of the hook and the edge of the guide opening, or the width of the gap formed between the end of the hook and the edge of the guide opening is greater than the diameter of the pin.

[0005] The guide rail is also provided with a second locking device. The first locking device and the second locking device are respectively located near the two ends of the guide rail. When the second locking device locks the guide rail and the slider, the inner opening of the hook opens outward, and the pin can disengage from or connect with the hook.

[0006] Through the above technical solution, the ladder can be disassembled and stored separately after the pin is detached from the hook, effectively reducing the overall volume of the rooftop tent after folding and storage. The user places the pin into the hook and pushes the slider until the first locking device is aligned with the locking guide rail and slider. The installation process is simple, quick, and easy. When the first locking device is aligned with the locking guide rail and slider, the space between the inner contour of the hook and the edge of the guide opening stably positions the pin. The pin can rotate relative to the guide rail and hook but cannot be disassembled separately, ensuring a very stable connection. The invention's structure is rationally designed, allowing the detachable ladder to balance connection stability and ease of installation. The hook can be positioned appropriately by locking the guide rail and slider with the second locking device, opening the inner opening of the hook outwards. The user can quickly slide the slider to the appropriate position and lock it using the second locking device to place the pin into the hook, facilitating ladder installation.

[0007] Furthermore, an inclined surface is provided on one end of the guide rail near the second locking device, and the inclined surface faces away from the base plate.

[0008] With the above technical solution, during the installation of the ladder, the pin can approach the hook while adhering to the inclined surface. The inclined surface guides the pin, making it easier to align the pin and place it into the hook, thus further facilitating the installation of the ladder.

[0009] Furthermore, the first locking device and the second locking device are respectively a first positioning hole and a second positioning hole, and the slider is provided with a positioning protrusion, and the first positioning hole and the second positioning hole are both adapted to the positioning protrusion.

[0010] Through the above technical solutions, the first locking device and the second locking device have simple structures and are easy to manufacture. Furthermore, rollers are rotatably arranged on both sides of the slider, with at least two rollers on each side of the slider. Slide grooves are provided on the inner walls of both sides of the guide rail, and the rollers are connected to the slide grooves.

[0011] With the above technical solution, each slide is connected to at least two pulleys, which makes the sliding contact between the slider and the guide rail more stable and avoids the slider getting stuck due to uneven force during the sliding process on the guide rail.

[0012] Furthermore, a first limiting block and a second limiting block are respectively provided on the guide rail. The first limiting block is close to or connected to one end of the guide rail, and the second limiting block is close to or connected to the other end of the guide rail. The slider is always located between the first limiting block and the second limiting block.

[0013] With the above technical solution, the range of motion of the slider on the guide rail is limited to between the first limit block and the second limit block, which prevents the slider and the hook from detaching from the guide rail and avoids the situation where the ladder cannot be connected to the guide rail due to the loss of the slider.

[0014] Furthermore, the guide rail is provided with a socket, and a pin is detachably connected to the socket; when the guide rail and the slider are locked relative to each other using the first locking device, the slider is located between the first limiting block and the pin. Through the above technical solution, when the slider is locked using the first positioning device, the pin and the first limiting block respectively abut and limit the slider at opposite ends. When the user climbs the ladder, the force on the ladder is transmitted to the slider through the hook and pin. The pin and the first limiting block can share the force on the slider in different directions, making the ladder connection more stable and secure.

[0015] Furthermore, the slider is provided with a threaded hole, and a stud is internally threaded into the threaded hole, with the positioning protrusion disposed on the end face of the stud.

[0016] Through the above technical solution, the extension distance of the positioning protrusion relative to the slider can be adjusted in time by rotating the stud. The user can rotate the stud to adjust the position of the positioning protrusion as needed. The stud can be screwed outward to make the connection between the positioning protrusion and the first or second positioning hole tighter. The stud can be screwed inward to reduce the difficulty of the positioning protrusion disengaging from the first or second positioning hole, making it easier to use.

[0017] Furthermore, there are two threaded holes and two studs, with positioning protrusions on the two studs located on both sides of the slider, and the first positioning hole and the second positioning hole are both located on both sides of the guide rail.

[0018] Through the above technical solution, the positioning protrusions on both sides of the slider simultaneously connect to two first positioning holes or two second positioning holes, making the force on both sides of the slider more even when using the first locking device or the second locking device, thus preventing the slider from jamming due to uneven force.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

See also Figures 1-10 A disassembly structure for a rooftop tent includes a base plate 1 and a ladder 2. The base plate 1 is provided with two guide rails 3 arranged parallel to each other. The guide rails 3 are provided with guide openings 301, which are strip-shaped and extend along the length of the guide rails 3. The ladder 2 is provided with axle pins 4 on both sides. A slider 5 is slidably connected in the guide opening 301, and a hook 6 is provided on the slider 5.

[0035] The guide rail 3 is also provided with a second locking device. The first locking device and the second locking device are respectively close to the two ends of the guide rail 3. When the second locking device locks the guide rail 3 and the slider 5, the inner opening of the hook 6 is open to the outside, and the shaft pin 4 can be disengaged from or connected to the hook 6.

[0036] Depending on the shape of the hook 6, the positional relationship between the hook 6 and the edge of the guide opening 301 during use will also be different, specifically in the following two cases;

[0037] Example 1: See Figure 6 The guide rail 3 is provided with a first locking device. When the guide rail 3 and the slider 5 are locked relative to each other by the first locking device, a closed annular area for placing the pin 4 is formed between the inner contour of the hook 6 and the edge of the guide opening 301.

[0038] Example 2: See Figure 7 A first locking device is provided on the guide rail 3. When the guide rail 3 and the slider 5 are locked relative to each other by the first locking device, the gap width formed between the end of the hook 6 and the edge of the guide opening 301 is greater than the diameter of the shaft pin 4. The preferred embodiment of the present invention is 1. Embodiments 1 and 2 are applicable to the following description.

[0039] After the pin 4 disengages from the hook 6, the ladder 2 is detached and stored separately, effectively reducing the overall volume of the rooftop tent after folding and storage. The user places the pin into the hook 6 and pushes the slider 5 until the first locking device is aligned with the locking guide rail 3 and the slider 5. The installation process is simple, quick, and easy. When the first locking device is aligned with the locking guide rail 3 and the slider 5, the space between the inner contour of the hook 6 and the edge of the guide opening 301 stably houses the pin 4. The pin 4 can rotate relative to the guide rail 3 and the hook 6 but cannot be disassembled separately, ensuring a very stable connection. The invention's structure is rationally designed, allowing the detachable ladder 2 to balance connection stability and ease of installation. By using the second locking device to lock the guide rail 3 and the slider 5, the hook 6 can be positioned appropriately, opening the inner opening of the hook 6 outwards. The user can quickly slide the slider 5 to the appropriate position and lock it using the second locking device to place the pin into the hook 6, facilitating the installation of the ladder 2.

[0040] See Figure 1 , 2 3, 5, 8, A ramp 302 is provided on one end of the guide rail 3 near the second locking device, and the ramp 302 is inclined away from the base plate 1.

[0041] During the installation of ladder 2, the pin can approach the hook 6 while adhering to the inclined surface 302. The inclined surface 302 guides the pin, making it easier to align and insert it into the hook 6, thus facilitating the installation of ladder 2. (See reference...) Figures 1-8 The first locking device and the second locking device are respectively the first positioning hole 303 and the second positioning hole 304. The slider 5 is provided with a positioning protrusion 7, and the first positioning hole 303 and the second positioning hole 304 are both adapted to the positioning protrusion 7.

[0042] The first and second locking devices have simple structures and are easy to manufacture.

[0043] The slider 5 is provided with a threaded hole 12, and a stud 13 is connected to the threaded hole 12 by an internal thread. The positioning protrusion 7 is provided on the end face of the stud 13.

[0044] The extension distance of the positioning protrusion 7 relative to the slider 5 can be adjusted in time by rotating the stud 13. The user can adjust the position of the positioning protrusion 7 by rotating the stud 13 as needed. The stud 13 can be screwed outward to make the connection between the positioning protrusion 7 and the first positioning hole 303 or the second positioning hole 304 more secure. The stud 13 can be screwed inward to reduce the difficulty of the positioning protrusion 7 disengaging from the first positioning hole 303 or the second positioning hole 304, making it easier to use.

[0045] See Figure 5 , 67. Preferably, the threaded hole 12 is provided through the slider 5, and preferably, the stud 13 is provided with an internal hexagonal hole 14 on the other end relative to the positioning protrusion 7. The user can use a wrench to turn the stud 13 with the internal hexagonal hole 14.

[0046] There are two threaded holes 12 and two studs 13. The positioning protrusions 7 on the two studs 13 are located on both sides of the slider 5. The first positioning hole 303 and the second positioning hole 304 are both located on both sides of the guide rail 3.

[0047] The positioning protrusions on both sides of the slider 5 simultaneously connect to the two first positioning holes 303 or the two second positioning holes 304, so that the slider 5 is subjected to more even force on both sides when using the first locking device or the second locking device, thus avoiding the situation where the slider 5 gets stuck due to uneven force.

[0048] See Figure 1 , 2 3, 4, 5, 8, 10. Rollers 8 are rotatably provided on both sides of slider 5. There are at least two rollers 8 on each side of slider 5. Slide grooves 305 are provided on the inner walls of both sides of guide rail 3. The rollers 8 are connected in slide grooves 305.

[0049] Each slide groove 305 is connected to at least two pulleys, making the sliding engagement between the slider 5 and the guide rail 3 more stable and preventing the slider 5 from getting stuck due to uneven force during the sliding process on the guide rail 3.

[0050] Two rollers 8 are preferably provided on each side of the slider 5.

[0051] See Figure 1 , 2 3, 4, 8, the guide rail 3 is respectively provided with a first limiting block 9 and a second limiting block 10. The first limiting block 9 is close to or connected to one end of the guide rail 3, and the second limiting block 10 is close to or connected to the other end of the guide rail 3. The slider 5 is always located between the first limiting block 9 and the second limiting block 10.

[0052] The range of motion of slider 5 on guide rail 3 is limited between the first limiting block 9 and the second limiting block 10, so as to prevent slider 5 and hook 6 from detaching from guide rail 3 and to prevent ladder 2 from being unable to be connected to guide rail 3 due to loss of slider 5.

[0053] Preferably, both the first limiting block 9 and the second limiting block 10 are screws, and the two screws are fixedly connected to the guide rail 3 near the two ends.

[0054] See Figure 3 , 45, 6, 7, 8, The guide rail 3 is provided with a socket 306, and a pin 11 is detachably connected to the socket 306; When the first locking device locks the guide rail 3 and the slider 5, the slider 5 is located between the first limiting block 9 and the pin 11.

[0055] When the first positioning device locks the slider 5, the pins 11 and the first limiting block 9 are respectively used to abut and limit the slider 5 on the opposite end faces. When the user climbs the ladder 2, the force on the ladder 2 will be transmitted to the slider 5 through the hook 6 and the pin. The pins 11 and the first limiting block 9 can share the force on the slider 5 in different directions, making the connection state of the ladder 2 more stable and firm.

[0056] See Figures 1-10 During installation, the slider 5 needs to be moved to a suitable position so that the positioning protrusions 7 on both sides of the slider 5 engage with the two second positioning holes 304. At this time, the inner opening of the hook 6 is open outward.

[0057] Then, the user needs to align the pins on both sides of the ladder 2 with the clips and engage them in the hooks 6. During this process, the inclined surface 302 can guide the pins.

[0058] Then, the user pushes the ladder 2 and causes the slider 5 to slide relative to the guide rail 3. During this process, the positioning protrusion 7 first disengages from the second positioning hole 304 until the positioning protrusion 7 and the first positioning hole 303 are engaged.

[0059] Finally, the pin 11 is inserted into the socket 306. In this state, a closed annular area for accommodating the pin 4 is formed between the inner contour of the hook 6 and the edge of the guide opening 301.

[0060] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
