Description

Rooftop tent with emergency drive and camper van including it

[0001] The present invention relates to a rooftop tent for a vehicle and a camping car including the same, and more particularly, to a rooftop tent capable of an emergency drive that can be manually operated in an emergency and a camping car including the same.

[0002] Camping is a traditional leisure activity, and related technologies are constantly being developed. Recently, with the spread of vehicle camping culture, including car camping, various technologies that combine camping and vehicles are being developed.

[0003] For example, vehicle-mounted tents (e.g., vehicle-mounted, side-extending, pop-up, etc.) are convenient because the vehicle body serves as the installation space. They also offer space-saving advantages, as they don't require separate tent storage space. For these reasons, they are favored by the camping public.

[0004] Among vehicle tents, rooftop tents, which are deployed from the vehicle roof, are fixedly attached to the vehicle, enhancing mobility. Most rooftop tents utilize actuators, such as motors or cylinders, to enable automatic opening and closing (e.g., Republic of Korea Patent No. 10-1318392).

[0005] However, outdoors, there's a need to adapt to a variety of situations. For example, if there's no power supply for a rooftop tent (e.g., a dead battery) or the actuators don't work for other reasons, the tent can become inoperable, potentially leading to a difficult situation. Furthermore, conventional rooftop tents suffer from structural instability, are fixed to the vehicle, making space expansion difficult, and their openable structure limits space. Therefore, an alternative was needed.

[0006] [Prior Art Literature]

[0007] (Patent Document 1) Republic of Korea Patent Publication No. 10-1318392, (October 15, 2013)

[0008] One technical objective of the present invention, aimed at resolving these issues, is to provide a rooftop tent that can be operated manually in an emergency, and a rooftop tent with an emergency operation that allows convenient opening and closing in any situation, both manually and automatically. Furthermore, a rooftop tent capable of folding, collapsing, and expanding using a variable structure is also provided. Another technical objective of the present invention is to provide a camping car that includes such a rooftop tent.

[0009] The technical problems of the present invention are not limited to the problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0010] A rooftop tent capable of emergency operation according to the present invention comprises: a tent cover; a base plate overlapping the lower portion of the tent cover and installed on a vehicle roof; a pair of lower rails formed on an upper portion of the base plate; a pair of upper rails formed at positions corresponding to the lower rails on the lower portion of the tent cover; a scissor lift unit including a pair of scissor lifts including a first support bar having one end hingedly connected to the lower rail and the other end slidably connected to the upper rail, a second support bar having one end hingedly connected to the upper rail and the other end slidably connected to the lower rail and intersecting the first support bar, and a pivot axis formed at an intersection of the first support bar and the second support bar; a first slide block slidably connected to the upper rail and to which the first support bar is fixed; a second slide block slidably connected to the lower rail and to which the second support bar is fixed; A driving cylinder including a cylinder body installed on the lower rail, fixed to the first support bar and including a screw rod rotatably coupled therein, and a driving motor for driving the screw rod, a nut block coupled to an outer circumferential surface of the screw rod and moving along the screw rod within the cylinder body as the screw rod rotates, and a driving bar having one end connected to the nut block and the other end fixed to the second slide block and moving the second slide block along the lower rail as the nut block moves; and a rotating handle detachably coupled to the driving cylinder and rotating the screw rod.

[0011] The above driving cylinder may further include an extension rod arranged in series on the same axis as the screw rod, one end of which is connected to the screw rod and the other end of which is exposed to the outside of the cylinder body or the driving bar and is coupled to the rotary handle.

[0012] The above rotary handle may include an outer rod arranged in series on the same axis as the extension rod, a coupling socket formed at one end of the outer rod and coupled with the other end of the extension rod, and an arm formed with a handle that protrudes perpendicularly from the other end of the outer rod and generates torque on the outer rod.

[0013] The above driving cylinder is installed horizontally parallel to the lower rail, so that the screw rod, the extension rod, and the outer rod can all rotate on the same axis parallel to the lower rail.

[0014] The above driving motor can be formed as a hollow shaft motor having a hollow shaft through which the screw rod penetrates and is coupled.

[0015] The upper rail and the lower rail include a flat plate portion overlapping the first support bar and the second support bar, and a pair of rail portions in the shape of circular bars that are positioned on the outside of the first support bar and the second support bar and are spread out on both sides of the flat plate portion, and the first slide block and the second slide block can each slide along the rail portion.

[0016] The first slide block and the second slide block may include a pair of holders having a guide hole formed on the inside through which the rail part passes and extending to the outside of the rail part to surround and combine the rail part from the outside of the rail part.

[0017] The first slide block and the second slide block may further include a friction adjusting ring that is positioned in close contact with the inner surface of the guide hole and interposed between the rail portion and the guide hole to adjust friction generated between the rail portion and the guide hole.

[0018] The tent cover is formed of a horizontally arranged plate, and may further include a side folding plate foldably arranged between the tent cover and the base plate to shield the side.

[0019] The above-mentioned side folding plate may further include a central hinge extending horizontally in the center, and both ends of which are folded symmetrically up and down based on the central hinge, and a soft elastic shielding film that overlaps the outside of the central hinge and is fixed to the side folding plate at both ends to shield the central hinge.

[0020] The tent cover may further include a thermal sensor that detects human body heat from the lower space of the tent cover.

[0021] It may further include a sliding deck inserted into the interior of the base plate or withdrawn to the side of the base plate.

[0022] An access hole formed through the sliding deck; and a movable ladder that is installed so as to be stored in the lower portion of the sliding deck and is mounted on a rail crossing the lower portion of the sliding deck so as to be able to change position with the access hole in between.

[0023] It may further include a door that is hinged to the above access hole and opens and closes, and a hinge locking module that locks the door by inhibiting rotation of the hinge.

[0024] The above hinge locking module includes a catch protruding from the hinge, so that when the movable ladder moves toward the hinge and catches on the catch, the hinge can be fixed.

[0025] The above movable ladder may include a catch bar arranged to intersect the catch piece at the upper end.

[0026] The above movable ladder may include a sliding hinge part that is connected to the rail at the upper end so as to be able to slide and that functions as a rotation axis of the movable ladder.

[0027] The withdrawal directions of the above rail and the above sliding deck may coincide with each other or intersect each other.

[0028] A camping car according to the present invention includes a rooftop tent capable of emergency operation; and a body having the rooftop tent capable of emergency operation installed on the roof.

[0029] According to the present invention, the rooftop tent can be operated both manually and automatically. Therefore, in an emergency, the user can directly operate the rooftop tent's drivetrain to open and close the tent, allowing for easy handling even when automatic operation is impeded outdoors. Furthermore, manual operation is extremely convenient, allowing anyone to easily open and close the tent. Furthermore, the structurally stable rooftop tent provides a safer camping experience. Furthermore, the tent space can be adjusted as needed, increasing utility. Furthermore, the entrance can be adjusted accordingly, enhancing user convenience. In rainy weather, the entrance is protected from rainwater, ensuring uninterrupted use. Furthermore, the improved structure makes the tent more compact when closed, reducing air resistance when moving the camper.

[0048] The advantages and features of the present invention, as well as the methods for achieving them, will become clearer with reference to the embodiments described in detail below together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below and may be implemented in various different forms. These embodiments are provided only to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined solely by the claims. Like reference numerals designate like elements throughout the specification.

[0049] Hereinafter, with reference to FIGS. 1 to 21, a rooftop tent capable of emergency operation and a camping car including the same according to the present invention will be described in detail. First, one embodiment of the invention will be described with reference to FIGS. 1 to 14, and then, based on the description, other embodiments of the invention will be described in detail with reference to the remaining drawings.

[0050] FIG. 1 is a perspective view of a rooftop tent capable of emergency operation according to one embodiment of the present invention, and FIG. 2 is a perspective view of the rooftop tent of FIG. 1 from another direction.

[0051] Referring to Fig. 1, the rooftop tent (1) (hereinafter, “rooftop tent”) capable of emergency operation according to the present invention is equipped with a scissor lift (71). The scissor lift (71) structurally stabilizes the tent by symmetrically supporting the upper surface (tent cover) and the lower surface (base plate) of the tent around a pivot axis (702). The rooftop tent (1) has a pop-up structure that can be used immediately by operating the scissor lift and unfolding it.

[0052] The scissor lift (71) can be operated by extending and contracting the drive cylinder (800). The drive cylinder (800) has a built-in drive motor, so it can be extended and contracted automatically. However, since the drive system connected to the motor is connected to the rotary handle (900), it can also be extended and contracted manually using the rotary handle (900). Accordingly, the scissor lift (71) can be operated automatically or manually, depending on the situation.

[0053] In other words, the present invention allows the user to manually operate the drive cylinder (800) and scissor lift (71) using the rotary handle (900) even in an emergency (e.g., when power supply is difficult due to battery discharge), so there is no problem in using the tent. Accordingly, it can effectively deal with various problems that may arise while camping (e.g., motor failure, power discharge, etc.).

[0054] In addition, the rooftop tent (1) can be used by expanding the space by using a sliding deck (30) that extends to the side of the base plate (20). The sliding deck (30) can be extended outward as shown in Fig. 1 or inserted into the base plate as shown in Fig. 3, so that the size of the tent space can be adjusted as needed.

[0055] The rooftop tent (1) of the present invention is configured as follows.A rooftop tent (1) comprises: a tent cover (10), a base plate (20) that overlaps the lower portion of the tent cover (10) and is installed on the vehicle roof; a pair of lower rails (50) formed on the upper portion of the base plate (20); a pair of upper rails (see 60 in FIG. 2) formed at positions corresponding to the lower rails (50) on the lower portion of the tent cover (10); a first support bar (see 710 in FIG. 8) having one end hinged to the lower rail (50) (see 701 in FIG. 8) and the other end slidably connected to the upper rail (60); a second support bar (see 720 in FIG. 8) having one end hinged to the upper rail (60) (see 701 in FIG. 8) and the other end slidably connected to the lower rail (50) and intersecting with the first support bar (710); and a second support bar (see 720 in FIG. 8) formed at the intersection of the first support bar (710) and the second support bar (720). A scissor lift unit (see 70 in FIG. 8) including a pair of scissor lifts (see 71, 72 in FIG. 8) including a pivot shaft (see 702 in FIG. 8), a first slide block (see 740 in FIG. 8) that is slidably connected to an upper rail (60) and has a first support bar (710) fixed thereto, a second slide block (see 730 in FIG. 8) that is slidably connected to a lower rail (50) and has a second support bar (720) fixed thereto, a cylinder body (see 801 in FIG. 11) that includes a screw rod (see 803 in FIG. 11) that is installed on the lower rail (50), is fixed to the first support bar (710) and is rotatably connected thereto, and a driving motor (see 804 in FIG. 11) that drives the screw rod (803), and a cylinder body (see 801 in FIG. 11) that is connected to an outer surface of the screw rod (803) so that as the screw rod (803) rotates, A drive cylinder (800) including a nut block (see 805 in FIG. 11) that moves along a screw rod (803) inside a cylinder body (801), a drive bar (see 802 in FIG. 11) that has one end connected to the nut block (805) and the other end fixed to a second slide block (730) so that the second slide block (730) moves along a lower rail (50) as the nut block (805) moves, and a rotary handle (900) that is detachably connected to the drive cylinder (800) and rotates the screw rod (803).

[0056] That is, the drive cylinder (800) of the present invention has a drive motor (804) and a screw rod (803) built into it, and is expanded and contracted by the rotation of the screw rod (803) (more specifically, the nut block that moves back and forth when the screw rod rotates converts the rotational motion into linear motion to operate the drive bar). The rotation handle (900) is detachable, so that when it is fastened to the screw rod (803), the screw rod (803) can be manually rotated at any time, and thus the present invention can be manually operated at any time when necessary.

[0057] In this embodiment, the rooftop tent (1) may further include the following configuration. The driving cylinder (800) may further include an extension rod (806) that is arranged in series on the same axis as the screw rod (803) and has one end connected to the screw rod (803) and the other end exposed to the outside of the cylinder body (801) or the driving bar (802) and coupled to a rotary handle (900), and the rotary handle (900) may include an outer rod (901) that is arranged in series on the same axis as the extension rod (806), a coupling socket (902) formed at one end of the outer rod (901) and coupled to the other end of the extension rod (806), and an arm (903) that is formed with a handle (903a) that protrudes vertically from the other end of the outer rod (901) and generates torque on the outer rod (901).

[0058] The drive cylinder (800) is installed horizontally parallel to the lower rail (50) as shown, so that the screw rod (803), the extension rod (806), and the outer rod (901) can all rotate on the same axis parallel to the lower rail (50). That is, since the drive cylinder (800) does not move and is fixed horizontally, the rotation handle (900) can also be coupled parallel to it and rotated stably. For example, if the drive cylinder (800) has a different arrangement in which the angle changes according to the raising and lowering of the scissor lift (e.g., when it is connected obliquely between the lower rail and the second support bar), the cylinder continues to move according to the operation of the scissor lift (71), so manual operation may be difficult.

[0059] In addition, in this embodiment, the rooftop tent (1) may further include a side folding plate (30) formed by a horizontally arranged plate with a tent cover (10) and foldable between the tent cover (10) and the base plate (20) to shield the side. Accordingly, a safer and more sturdy rooftop tent can be realized by shielding both the upper and lower surfaces and the side surfaces.

[0060] In addition, a sliding deck (210) is installed on the base plate (20), so that it can be inserted into the inside of the base plate (20) or pulled out to the side of the base plate (20) for use. A movable ladder (220) is also installed on the sliding deck (210), so that it is easy to enter and exit the tent even when it is expanded.

[0061] Hereinafter, the configuration and operational effects of the present invention will be described in more detail based on one embodiment of the present invention.

[0062] FIG. 4 is an operation diagram showing the opening and closing operation of the rooftop tent of FIG. 1, FIG. 5 is a perspective view showing the rooftop tent of FIG. 1 with the tent cover and side folding plates separated, FIG. 6 is an operation diagram showing the storage method of the side folding plates of FIG. 5, FIG. 7 is a diagram showing a modified example in which a side shield is applied instead of the side folding plates of FIG. 5, and FIG. 8 is an exploded view of a scissor lift part included in the rooftop tent of FIG. 1.

[0063] First, referring to Fig. 1, the exterior of the rooftop tent (1) will be described as follows. Referring to Fig. 1, the rooftop tent (1) may include a tent cover (10), a side folding plate (30), a base plate (20), and a side rotating plate (40). The tent cover (10) and the base plate (20) correspond to each other vertically and close or open, and the side folding plate (30) and the side rotating plate (40) are folded therebetween and stored between the tent cover (10) and the base plate (20). Therefore, the rooftop tent (1) can be fixed to the vehicle roof by folding the tent cover (10) and the base plate (20) adjacent to each other. This state is illustrated in Fig. 4 (d).

[0064] The tent cover (10), side folding plate (30), base plate (20), and side rotating plate (40) may all be formed as plates. Each plate may include a honeycomb-shaped support structure (101) therein, as shown in FIG. 1. Therefore, a lightweight yet sturdy tent can be constructed. The size of the tent may vary depending on the vehicle size, roof area, etc., and the shape of each plate including the tent cover (10) may also be modified if necessary. Therefore, the shape illustrated in FIG. 1 should be understood as an example.

[0065] In the case of the base plate (20), it can have an appropriate thickness to accommodate the sliding deck (210) inside. The base plate (20) includes a side opening (200a) on the side through which the sliding deck (210) enters and exits, so that the sliding deck (210) can be pulled out laterally. In such a case, the base plate (20) can also be formed as a double-structured plate body with a space formed inside.

[0066] The base plate (20) can be fixed to a vehicle (see 2 in FIG. 14). The base plate (20) is a lower structure that supports the entire rooftop tent (1) and serves as the base of the rooftop tent (1). When the base plate (20) is installed on the vehicle roof, the rooftop tent (1) is mounted on the vehicle (see FIG. 14). The base plate (20) can be firmly fixed to the vehicle roof using bolting or other various fastening methods. The lower rail (50) is mounted on the base plate (20), so it can be fixed to the vehicle together with the base plate (20). However, since the base plate (20) can be replaced with the vehicle body if necessary, it is not necessary to understand the configuration in a limited manner. The vehicle installation state of the rooftop tent will be described in detail later.

[0067] Referring to Fig. 2, the sliding deck (210) can be slidably coupled to the base plate (20). A guide portion (213) that guides the sliding movement can be arranged between the sliding deck (210) and the base plate (20). The guide portion (213) can be formed as a sliding bar that is fixed to the sliding deck (210) on one side and fixed to the base plate (20) on the other side and is elastic, and can also be formed as a sliding bar that is extended in multiple stages. The guide portion (213) can guide the sliding movement of the sliding deck (30) and can also play a role in supporting both sides by combining the sliding deck (210) and the base plate (20), so that the supporting force of the sliding deck can be increased by installing a plurality of guide portions (213).

[0068] When the sliding deck (210) is formed, a movable ladder (220) and a variable support member (214) that can be stored can also be installed under the sliding deck. The movable ladder (220) can be moved along a rail (212) installed on the sliding deck (210) and can also be folded by rotating the top about an axis. The variable support member (214) is also hinged to the sliding deck (210) so that it can be unfolded downward (see FIG. 1), and can be supported on the floor by extending in the longitudinal direction when unfolded. Therefore, when the sliding deck (30) is withdrawn, the tent can be installed more stably by supporting the floor with the movable ladder (220) and the variable support member (214).

[0069] Referring to FIG. 1, the tent cover (10) is formed as a square plate, and the base plate (20) can also be formed in a corresponding shape. A gap cover (102) that blocks the gap between the base plate (20) and the tent cover (10) when the tent is folded can also be formed on the edge of the tent cover (10). The gap cover (102) can also be formed as a solid plate, but can also be implemented in a curtain shape, etc., if necessary, and thus is not limited to a specific structure. The gap cover may be opened by forming a cutout at the insertion position of the rotary handle (900) to facilitate manual operation, if necessary. In the drawing, the gap cover (102) is drawn in phantom lines to reveal the movable structure, and the gap cover is omitted in other drawings.

[0070] A thermal sensor (see 11 in FIG. 1 - omitted in other drawings) for detecting human body heat may also be disposed on the tent cover (10). That is, the rooftop tent (1) may include a thermal sensor (11) disposed on the tent cover (10) for detecting human body heat from the lower space of the tent cover (10). The thermal sensor (11) detects human body heat to determine whether there is a living being, such as a person, in the inner space of the tent (i.e., the lower space of the tent cover) before folding the tent. For example, it is also possible to control the operation of the thermal sensor (11) and the drive motor (see 804 in FIG. 11) of the drive cylinder (800) or the controller controlling it to automatically stop the operation of the drive motor (804) when a sensor detection value is input upon detection of body heat by connecting the thermal sensor (11) and the drive motor (800) or the controller controlling the same. In addition, when manually operating using the rotary handle (900), an alarm unit (e.g., a display device and / or a speaker) that generates a light signal and / or a warning sound when body heat is detected can be activated to notify the user that there is a person inside the tent. That is, the rooftop tent (1) can be switched to a safety mode in which automatic operation is stopped when there is a person inside the tent according to the detection value of the heat detection sensor (11), thereby protecting the person inside the tent. Through such control, the rooftop tent can be opened and closed more safely.

[0071] The rooftop tent (1) can be completely folded as shown in FIGS. 3 and 4. That is, in the unfolded state as shown in FIG. 1, the sliding deck (210) is inserted into the base plate (20) as shown in FIG. 3, and then the scissor lift (71) is operated in the steps of FIG. 4 to completely fold the entire tent. When inserting the sliding deck (210), the movable ladder (220) and variable support can be folded first, stored under the sliding deck (210), and then inserted (see FIG. 3). In another embodiment, if the sliding deck is not applied, the steps of FIG. 4 can be performed immediately to fold the rooftop tent.

[0072] Referring to FIG. 4, the rooftop tent is folded by inserting the sliding deck into the base plate (20) as in FIG. 4 (a), rotating the side pivot plate (40) as in FIG. 4 (b) to make it adhere to the lower surface of the tent cover (10), and folding the side folding plate (30) as in FIG. 4 (c) so that both the side folding plate (30) and the side pivot plate (40) can be stored between the tent cover (10) and the base plate (20). As a result, the rooftop tent (1) is folded compactly as in FIG. 4 (d) with the side folding plate and the side pivot plate built in. At this time, the gap cover (see 102 in FIG. 1) described above blocks the gap between the tent cover (10) and the base plate (20), so that the tent is watertight even when folded. If this operation is performed in reverse, the tent can be unfolded again.

[0073] At this time, when the rotary handle (900) is coupled to the driving cylinder (800) (can be coupled via an extension bar (806 in FIG. 1) or the like) and rotated, the driving cylinder (800) and the scissor lift (71) are manually operated. That is, as in FIG. 4, the rooftop tent (1) can be manually folded or unfolded by manually operating the scissor lift (71) with the rotary handle (900). By using the rotary handle (900), the opening and closing operation as in FIG. 4 can also be performed manually.

[0074] However, since the drive cylinder (800) has a built-in drive motor (see 804 in FIG. 11), it automatically expands and contracts when power is supplied. Therefore, in normal times when manual operation is not required, the opening and closing operation is performed exactly the same as in FIG. 4 without the rotary handle (900). That is, the operation using the rotary handle in FIG. 4 should be understood as an example for demonstrating the features of the present invention. Since the rooftop tent (1) of the present invention allows both manual and automatic operation of the drive cylinder (800), the user can select and operate the drive method as needed. The structure of the drive cylinder (800) that allows such operation will be described in detail later.

[0075] Figures 5 and 6 illustrate the side structure of the rooftop tent in more detail. Referring to Figures 5 and 6, the side folding plate (30) may include a central hinge (310) extending horizontally in the center, and may have a structure in which both ends fold symmetrically up and down based on the central hinge (310). A soft elastic shielding film (320) may be arranged on the outside of the central hinge (310) so as to overlap the central hinge (310) and have both ends fixed to the side folding plate (30) to shield the central hinge (310). This enables effective watertightness even in rainy weather.

[0076] Referring to the enlarged views of FIGS. 5 and 6, the elastic shielding film (320) can be flexibly deformed on the outside of the center hinge and shield the center hinge (310) (the enlarged views of FIGS. 5 and 6 are cross-sectional views of the center hinge portion). Both ends of the elastic shielding film (320) can be inserted into and fixed to the fixed holder (321) formed on the side folding plate (30). The non-fixed side can be deformed in response to the rotation of the center hinge (310). The elastic shielding film (320) can be formed of a soft rubber material or the like, and can be formed in the shape of a strap having a length corresponding to the length of the center hinge (310).

[0077] An inner watertight portion (330) may also be formed on the opposite side of the elastic shielding film (320). The inner watertight portion (330) may serve to seal the gap in the folding portion of the side folding plate (30) where the center hinge (310) is located. Since the elastic shielding film (320) and the inner watertight portion (330) seal on both sides of the center hinge (310) as shown, the side folding plate (30) can be very effectively watertight even though it has a folding structure. The inner watertight portion (330) may be formed of, for example, a rubber bar having a length corresponding to the length of the center hinge (310).

[0078] An outer watertight portion (410) that surrounds the perimeter of the side pivot plate (40) as shown in Fig. 5 may also be formed. The outer watertight portion (410) may be formed of a ring made of a soft rubber material, etc. The outer watertight portion (410) seals the gap between the side pivot plate (40) and the side folding plate (30) and may also seal the gap with the base plate. This watertight structure enhances the soundproofing and waterproofing effects of the rooftop tent.

[0079] Although the specific city is omitted, the side pivot plate (40) can be hinged at the top to the bottom of the tent cover (10). Therefore, it can be rotated as shown in (b) of Fig. 4 and stored in a close contact state against the bottom of the tent cover (10). When the side pivot plate (40) is unfolded, the bottom can be in close contact with the base plate.

[0080] The side folding plate (30) can also be hingedly connected to the tent cover (10) and the base plate (20) at the top and bottom, respectively. The side folding plate (30) can be folded and stored in a form similar to a kind of folded plate, as shown in (a) of Fig. 6, when the upper and lower hinges and the central hinge (310) operate simultaneously.

[0081] Although omitted from the drawing, the tent cover (10), side folding plate (30), side rotating plate (40), and base plate (20) may form a structure (e.g., a window or an entrance / exit) that can be partially opened or closed. If necessary, a portion of the plate-like structure may be opened to form a window, entrance / exit, etc. as appropriate. Since such a structure can be formed as needed, its specific illustration is omitted from the drawing.

[0082] Meanwhile, the rooftop tent can also be applied by changing the side shielding structure to a soft side shield (30-1) as shown in FIG. 7. The side shield (30-1) can be formed of, for example, waterproof cloth or a waterproof-coated functional fabric, and can be installed by connecting the upper end to the lower surface of the tent cover (10). Although not shown, the lower end of the side shield (30-1) can be directly fixed to a base plate or a vehicle body. The side shield (30-1) can surround and shield the entire side space under the tent cover (10), and thus can shield the space with a single structure. As shown, an entrance / exit structure such as a window can be easily formed in the side shield (30-1) formed of fabric or the like.

[0083] This side shield (30-1) can be stored by being folded as a whole simultaneously when the tent cover (10) is raised as shown in (b) of Fig. 7. In other words, the side shield structure can be transformed into a soft membrane, cotton, or fabric, rather than a plate structure, to form a structure that can be folded as a whole for easier storage. In this way, the side shield structure can be transformed into any easily foldable structure such as a membrane, cotton, or fabric, in addition to the side folding plate, like the side shield, so the above-described structure (side folding plate, etc.) is not limited. The present invention can select and apply any of the illustrated side shield structures as needed.

[0084] FIG. 8 illustrates in detail a scissor lift unit (70) installed between a tent cover (10) and a base plate (20). Referring to FIG. 8, the scissor lift unit (70) includes a pair of scissor lifts (71, 72) arranged at both ends of the tent cover (10). A pair of upper rails (60) are formed on the lower (or lower) side of the tent cover (10), a pair of lower rails (50) are formed on the upper side of the base plate (20), and a pair of scissor lifts (71, 72) are arranged between them so that the upper and lower ends are connected to the upper rail (60) and the lower rail (50), respectively, to form the scissor lift unit.

[0085] Since the pair of scissor lifts (71, 72) are substantially identical in structure as illustrated, the structure and operation will be described in more detail below based on one scissor lift. The following description of the scissor lift applies equally to both scissor lifts, even if not otherwise specified. The scissor lift and the drive cylinder that drives the scissor lift will be described in more detail below.

[0086] Fig. 9 is an operation diagram illustrating automatic operation of the scissor lift part of Fig. 8, and Fig. 10 is an operation diagram illustrating manual operation of the scissor lift part of Fig. 8. The two drawings differ only in the presence or absence of a rotary handle combination, and the shape of the scissor lift is the same. Therefore, the structure of the scissor lift will be described with reference to Fig. 9 first, and then Fig. 10 will be referred to when explaining manual operation using a rotary handle.

[0087] Referring to FIG. 9, the scissor lift (71) includes a first support bar (710) having one end connected to the lower rail (50) by a hinge (701) and the other end slidably connected to the upper rail (60), and a second support bar (720) having one end connected to the upper rail (60) by a hinge (701) and the other end slidably connected to the lower rail (50). The first support bar (710) and the second support bar (720) intersect each other, and a pivot axis (702) is formed at the intersection. Accordingly, the support bars on both sides can rotate crosswise about the pivot axis (702) to fold as in FIG. 9 (a) or unfold as in FIG. 9 (b).

[0088] The first support bar (710) and the second support bar (720) have their other ends that are not connected to the hinges so as to slide along the upper rail (60) and the lower rail (50). As shown, the other ends of each support bar are connected to a first slide block (740) and a second slide block (730). The first slide block (740) is slidably connected to the upper rail (60) so that the first support bar (710) is fixed, and the second slide block (730) is slidably connected to the lower rail (50) so that the second support bar (720) is fixed. In this case, fixing means that the other ends of each support bar are fixed to the slide blocks so that they move together with each slide block. Each support bar is axially connected to each slide block.

[0089] The first slide block (740) and the second slide block (730) can be connected to the other end of the first support bar (710) and the other end of the second support bar (720) by axes (730a, 740a), respectively. Therefore, the angles can be changed. Since the inclination of each support bar changes as the scissor lift is operated, this structure can be used to cope with it. The axes (730a, 740a) are not particularly limited within the range of rotation, and thus include hinge axes, etc. Each support bar can be connected to the corresponding slide block by an axis so as to be able to change the angle and be fixed thereto.

[0090] The first slide block (740) and the second slide block (730) are slidably connected to the upper rail (60) and the lower rail (50), respectively. As described later, the upper rail (60) and the lower rail (50) are formed with rail portions (see 510 and 610 of FIG. 13) that are flared outward, so that each slide block is connected in a structure that grips the rail portion from the outside. Due to the flared rail portions, interference between the rail portions and the support bars is eliminated, so that each rail (upper rail and lower rail) is arranged more closely when folded. This can reduce the gap between the tent cover (10) and the base plate, and can also reduce the cross-section when the rooftop tent (1) is folded more compactly. The connection structure between the slide blocks and each rail will be described in more detail later.

[0091] A stopper (704) may also be installed on the first support bar (710) and the second support bar (720) to maintain a gap therebetween. The stopper (704) is formed to protrude from one of the first support bar (710) and the second support bar (720) toward the other, and is interposed between the first support bar (710) and the second support bar (720) when they are adjacent to each other. Accordingly, even when the scissor lift (71) is folded as shown in (a) of FIG. 9, the gap between the two support bars can be maintained and they can be arranged in parallel.

[0092] One end of the first support bar (710) and one end of the second support bar (720) are connected to the lower rail (50) and the upper rail (60), respectively, by a hinge (701). Since the two support bars are crossed and connected by a pivot axis (702), they rotate in opposite directions around the hinge (701) and simultaneously fold or unfold. The hinge (701) may be formed at the end of each rail (upper rail and lower rail).

[0093] The driving cylinder (800) is installed on the lower rail (50), and both ends are fixed to the first support bar (710) and the second slide block (730) to adjust the gap between the two sides in the horizontal direction. More specifically, the cylinder body (see 801 of FIG. 11) of the driving cylinder (800) is fixed to the first support bar (710), and the driving bar (see 802 of FIG. 11) inserted into the cylinder body is fixed to the second slide block (730), so that the driving bar is elastic with respect to the cylinder body, and the gap between the first support bar (710) and the second slide block (730) [more specifically, the horizontal gap between the end of the first support bar (710) where the hinge (701) is formed and the second slide block (730)] can be changed. When the driving cylinder (800) is extended, the lower gap of the scissor lift (71) changes as shown in Fig. 9, so the upper gap also changes in the same manner around the pivot shaft (702), and the scissor lift (71) folds up and down [(a) of Fig. 9] or unfolds [(b) of Fig. 9].

[0094] At this time, the extension rod (806) protruding from the drive cylinder (800) can remain exposed regardless of the expansion and contraction of the drive cylinder (800) and can be arranged parallel to the lower rail (50) by penetrating the end of the drive bar (802) and the second slide block (730) fixed to the drive bar (802). The extension rod (806) can be exposed to the outside of the drive bar (802) and coupled to a rotary handle (see 900 in FIG. 10).

[0095] That is, the present invention can expand or contract the vertical gap between the upper rail (60) and the lower rail (50) by horizontally expanding and contracting the drive cylinder (800) as in FIG. 9. At this time, the drive cylinder (800) can be automatically expanded and contracted by the drive motor (804) as in FIG. 9, or can be manually expanded and contracted by the rotation of the rotary handle (900) as in FIG. 10. When the rotary handle (900) is used, the extension rod (806) can act as a mediating structure that transmits the rotational force to the drive cylinder (800). That is, the drive cylinder (800) can be operated both automatically by the built-in drive motor (804) as in FIG. 9, and manually by the manual operation of the rotary handle (900) as in FIG. 10. Therefore, the scissor lift (71) is also operated automatically or manually. This effect is possible due to the structure of the drive cylinder (800) described below. Hereinafter, the internal structure of the drive cylinder (800) will be described in more detail.

[0096] Fig. 11 is a cross-sectional view showing the internal structure of the drive cylinder mounted on the scissor lift of Fig. 10, and Fig. 12 is a perspective view showing the method of coupling the drive cylinder and the rotary handle of Fig. 11.

[0097] Referring to the cross-sectional view of Fig. 11, the driving cylinder (800) includes a cylinder body (801) installed on the lower rail (50) and fixed to the first support bar (710), and a driving bar (802) that is flexibly (or slidably) connected to the cylinder body (801) and fixed to the second slide block (730). That is, the driving cylinder is formed so that the cylinder body (801) is fixed to the first support bar (710) side and the driving bar (802) is fixed to the second slide block (730) side, so that the second slide block is slidably moved by pushing or pulling the driving bar.

[0098] The cylinder body (801) and the drive bar (802) may be long, concentrically connected bodies, and thus may have an internal space. The drive bar (802) may be slidably connected to the inside of the cylinder body (801). Accordingly, the length of the drive cylinder (800) may be varied as the drive bar (802) is inserted into the cylinder body (801) or protrudes from the cylinder body (801).

[0099] A screw rod (803) and a driving motor (804) are installed inside the cylinder body (801). The screw rod is installed across the inside of the cylinder body, and the driving motor provides power to the screw rod to rotate it. The screw rod (803) is rotatably coupled to the inside of the cylinder body (801) and is arranged in the longitudinal direction of the cylinder body (801). The screw rod (803) can be rotatably supported by a support structure formed inside the cylinder body. The screw rod (803) has screw threads (screws) formed on its surface, and thus power can be transmitted using the screw threads.

[0100] The drive motor (804) can be arranged in various forms that can drive the screw rod (803). Since the motor driving method of the screw rod (803) can be both direct driving by the motor and / or indirect driving by the motor and a power transmission mechanism (e.g., gear, chain, belt, etc.), the arrangement of the drive motor (804) and the screw rod (803) needs to be understood as broadly as possible. For example, the drive motor (804) can be formed as a hollow shaft motor having a hollow shaft (see enlarged view of 804a) through which the screw rod (803) passes and is coupled, so that the screw rod can be driven in a state in which it is directly connected to the screw rod.

[0101] That is, as in the present embodiment, a driving motor (804) having a hollow shaft (804a) formed inside a cylinder body (801) can be installed so that the screw rod (803) can pass through the driving motor (804) and be coupled. In such a case, the driving motor (804) can serve as a driving unit that rotates the screw rod (803) and also as a support structure that rotatably supports the screw rod (803).

[0102] The nut block (805) is coupled (screw-coupled) to the outer surface of the screw rod (803) and moves along the screw rod (803) inside the cylinder body (801) as the screw rod (803) rotates (see enlarged view). The nut block (805) has an inner surface on which screw threads (not shown) are formed and engages with the outer surface of the screw rod (803) on which corresponding screw threads are formed. Although briefly illustrated, the inner surface of the nut block (805) may have screw threads that engage with the screw threads formed on the outer surface of the screw rod (803). The nut block (805) is fixed to the drive bar (802) and does not rotate when the screw rod (803) rotates. Therefore, the screw threads of the screw rod (803) are pushed forward or backward by the pushing force and are moved back and forth (see arrows in the enlarged view). As a result, the rotational motion of the screw rod is converted into the linear motion of the nut block.

[0103] The shape and size of the nut block (805) can be changed as much as possible within the limits of such an action, so the drawing should be understood as an example. Since one end of the drive bar (802) is connected to the nut block (805) and the other end is fixed to the second slide block (730), the nut block (805), the drive bar (802), and the second slide block (730) move together. Therefore, the drive bar (802) can move and expand in the longitudinal direction of the screw rod (803) together with the nut block (805). In this way, the drive bar (802) of the drive cylinder (800) can be expanded and contracted using the power conversion device (screw rod and nut block) built into the drive cylinder. As a result, when the gap between the second slide block (730) and the first support bar (710) changes, the scissor lift (71) is raised and lowered.

[0104] The nut block (805) can be fixed to the drive bar (802) without moving by screwing, etc. However, the method of connection is various and therefore need not be limited to the example. The nut block (805) can be fixed to the end of the drive bar (802) without rotating in various ways. Since the other end of the drive bar (802) is fixed to the second slide block (730), the second slide block (730) slides in the direction in which the drive bar is extended (see the arrow in the enlarged view). By appropriately adjusting the size of the cylinder body (801), the length of the drive bar (802), etc., the extension distance of the drive bar can be adjusted and the corresponding operating range of the second slide block (730) can also be adjusted.

[0105] Therefore, the length of the driving cylinder, the length of the cylinder body, and the length or shape of the driving bar need not be limited to the drawings. The driving bar can be inserted into the cylinder body and then protruded outward, and can be formed to have an appropriate length that can move the second slide block to a distance that allows the scissor lift to be driven. The second slide block (730) can be moved as much as necessary using a driving cylinder (800) having an appropriate range of motion.

[0106] A watertight structure such as an O-ring (see enlarged drawing 807) can also be applied to the contact surface between the drive bar (802) and the cylinder body (801). This prevents the inflow of impurities, thereby more effectively protecting the internal structure of the drive cylinder (800). In this way, a drive cylinder (800) having a screw rod and a nut block positioned internally can be configured.

[0107] The rotary handle (900) is detachably coupled to the drive cylinder (800) and is connected to the internal screw rod (803) when coupled. Therefore, the screw rod (803) can be rotated by the rotary handle (900). The rotary handle (900) can be coupled to the drive cylinder in various ways that can be connected to the screw rod (803), and when properly coupled, can also be directly connected to the screw rod (803). However, as in the present embodiment, it may be convenient to connect via a connecting rod (806) that is an extension of the screw rod (803).

[0108] The screw rod (803) and the rotary handle (900) can be directly connected, but can also be connected via an extension rod (806) as in this embodiment. That is, the driving cylinder (800) can include an extension rod (806) that is arranged in series on the same axis as the screw rod (803), with one end connected to the screw rod (803) and the other end exposed to the outside of the cylinder body (801) or the driving bar (802). The rotary handle (900) can be connected to the screw rod via the extension rod (806) to rotate the screw rod (803).

[0109] Since the extension rod (806) is a structure in which the screw rod (803) is extended and the end is exposed to the outside of the drive cylinder (800), the direction of exposure can also change depending on the direction in which it is coupled to the screw rod. For example, if the extension rod is coupled to the end of the screw rod on the cylinder body side, it can be exposed to the outside of the cylinder body, and conversely, if it is coupled to the end of the screw rod on the drive bar side, it can be exposed to the outside of the drive bar. Since the drive motor having the hollow shaft formed as described above exposes both ends of the screw rod, selective coupling of the extension rod using both ends of the screw rod is possible.

[0110] However, in this embodiment, a structure in which the extension rod (806) is exposed to the outside of the drive bar (802) is described, and a structure in which the second slide block (730) connected to the end of the drive bar (802) is also penetrated and exposed to the outside of the second slide block (730) is described. That is, one end of the extension rod (806) is connected to the screw rod (803), and the other end passes through the drive bar (802) and then passes through the second slide block (730) to be exposed to the outside.

[0111] Referring to the enlarged view of Fig. 11, the extension rod (806) can be extended from the screw rod (803) to the inside of the drive bar (802). The drive bar (802) is formed as a hollow cylinder structure inside so that the extension rod (806) can pass inside. The extension rod (806) and the screw rod (803) are arranged in series (meaning arranged in a straight line) on the same axis, and a coupler (806a) can also be used when joining. The coupler (806a) can be a structure that fixes one end of the extension rod (806) and the end of the screw rod (803) on both sides so that their centers of rotation are aligned, thereby joining the two sides in a state where they are placed on the same axis. However, the coupler is not essential, so if necessary, the screw rod and the extension rod can be directly joined by welding or the like.

[0112] The extension rod (806) can be exposed to the outside through a through-hole (735) of a second slide block (730) fixed to an end of the drive bar (802) after passing through the inside of the drive bar (802). The drive bar (802) is formed as a cylinder with both ends open, so that the extension rod (806) can be passed inside regardless of expansion and contraction, and the second slide block (730) that moves together with the drive bar (802) has a through-hole (735) formed at the end that exposes the extension rod (806) to the outside, so that the extension rod can be exposed through the through-hole (735). Therefore, as illustrated, a rotary handle (900) can be coupled to the extension rod (806) exposed to the outside to rotate the screw rod (803) (see enlarged view).

[0113] The extension rod (806) extends to the end of the lower rail (50) and can be conveniently combined with the rotary handle (900). Since the extension rod (806) only rotates and does not expand, when the nut block (805) moves and the drive bar (802) is inserted into the cylinder body (801), more of the extension rod can be exposed to the outside (see Fig. 10). In this way, by using the extension rod with one end connected to the screw rod and the other end exposed to the outside, manual operation using the rotary handle can be made more convenient.

[0114] A rotary support (810) that supports a rotary handle (900) may also be arranged at the end of the lower rail (50). The rotary support (810) may be formed in various shapes capable of supporting the rotary handle, and may also have a block structure as illustrated. The rotary support (810) may include an insertion hole (811) through which the rotary handle passes. If necessary, the end of the extension rod (806) may be extended into the insertion hole (811) of the rotary support (810). In this way, by arranging the extension rod connected to the screw rod, the rotational force can be transmitted to the screw rod via the extension rod.

[0115] The rotary handle may be detachably fixed to the end of the extension rod (806) by a coupling socket (902) at the end thereof. The rotary handle (900) may include, for example, an outer rod (901) arranged in series on the same axis as the extension rod (806), a coupling socket (902) formed at one end of the outer rod (901) to couple with the other end of the extension rod (806), and an arm (903) having a handle (903a) formed thereon that protrudes vertically from the other end of the outer rod (901) and generates torque on the outer rod (901). As a result, the screw rod (803), the extension rod (806), and the outer rod (901) can all rotate in a coupled state on the same axis.

[0116] Fig. 12 illustrates a perspective view of a method of coupling a rotary handle and an extension rod. As illustrated in Fig. 12, the rotary handle (900) is detachably coupled to an end of an extension rod (806) that is exposed to the outside of the second slide block (730) through the drive bar (802). The coupling socket (902) of the rotary handle (900) and the exposed other end of the extension rod (806) may have a coupling surface processed into a polygonal shape or the like to facilitate the transmission of rotational force. For example, a polygonal groove may be formed on the inside of the coupling socket (902) and a matching polygonal outer peripheral portion may be formed on the other end of the extension rod (806) so that they may be coupled in a manner of engaging each other.

[0117] In this way, when the rotary handle (900) is connected to the driving cylinder (800) via the extension rod (806), the outer rod (901) of the rotary handle (900), the extension rod (806), and the screw rod inside the driving cylinder (see 803 in FIG. 11) are arranged in a row on the same axis. Therefore, they can be rotated simultaneously while being connected in series on the same axis. As described above, the screw rod (803) is also connected to the shaft of the driving motor (see 804 in FIG. 11), but since the shaft of the motor rotates freely when no electric force is supplied, manual driving is also not a problem. That is, since the screw rod can be connected to both the driving motor and the rotary handle, when the driving motor (804) is operated, the screw rod (803) rotates by the power of the motor, and when the rotary handle (900) is connected and an external force is applied, the screw rod (803) can also be rotated manually. Therefore, the user can operate the rooftop tent manually or automatically as desired.

[0118] If necessary, an inlet portion (see 800a in the enlarged view of FIG. 11) that can be used to connect a power circuit or a control circuit, etc., can be formed on one side of the drive cylinder (800). The inlet portion can be arranged adjacent to the drive motor. For example, the inlet portion (800a) can be used for purposes such as connecting an external power source or a controller that controls the motor to the drive motor (804) via a wire. However, this is just one example, and the inlet portion may be removed in other embodiments. When the inlet portion is formed, the inlet portion can be appropriately sealed to be watertight.

[0119] Using this drive cylinder (800), the rooftop tent can be operated manually at any time by combining it with a rotary handle, even in an emergency. The rotary handle (900) can be installed in the vehicle and used by combining it with the drive cylinder (800) whenever necessary. Therefore, the rooftop tent can be unfolded and used even when there is no power, and after use, it can be manually folded, mounted on the vehicle, and then transported. Therefore, camping using the rooftop tent outdoors is possible without being restricted by power or other factors.

[0120] Fig. 13 is a perspective view and a side view showing the joint structure of the upper rail, lower rail, first slide block, and second slide block applied to the rooftop tent of Fig. 1.

[0121] The structural features of the slide block and rail portion of the present invention will be described in more detail with reference to FIG. 13 below. In FIG. 13, the aforementioned rotary support is drawn in dotted lines to reveal the structure of the slide block.

[0122] Referring to Fig. 13, both the upper rail (60) and the lower rail (50) of the present invention are formed with rail portions (510, 620). Referring to the side view of Fig. 13(b), the upper rail (60) and the lower rail (50) include flat plate portions (520, 620) that overlap (vertically) the first support bar (710) and the second support bar (720), respectively, and rail portions (510, 610) formed in the shape of a pair of circular bars that are spread out on both sides of the flat plate portions and are positioned outside the first support bar (710) and the second support bar (720) (and therefore positioned so as not to overlap with the support bars). That is, a pair of rail parts (610) that are flared outwardly are formed on both sides of the flat plate part (620) of the upper rail (60), and a pair of rail parts (510) that are flared outwardly are also formed on both sides of the flat plate part (520) of the lower rail (50). The structures of the upper rail and the lower rail may be symmetrical to each other. The first slide block (740) and the second slide block (730) are formed to slide along these rail parts (510, 610).

[0123] That is, the rail portions (510, 610) that guide the movement path of the slide blocks (the first slide block and the second slide block) have a characteristic of being spread outward from each support bar so as not to come into contact with the support bars (the first support bar and the second support bar) of the scissor lift (71). Therefore, the upper rail (60) and the lower rail (50) can be folded more closely with less interference with the support bars [(b) of FIG. 13]. For example, if the rail portions (510, 610) are arranged inside each flat plate portion (520, 620), the first support bar (710) and the second support bar (720) interfere with the rail portions (510, 610) protruding from the flat plate portion (520, 620) when folded, so that the gap between the upper (upper rail) and the lower (lower rail) of the rooftop tent can be greatly increased when folded. In such cases, since the rooftop tent is not compact, problems such as air resistance may increase when the vehicle is moved. The present invention solves this problem by using rail sections (510, 610) that are positioned so as to extend outward from the flat section (520, 620) and not come into contact with the support bar.

[0124] That is, the rail portions (510, 610) of the present invention have the effect of reducing interference between the upper rail (60) and the lower rail (50) and the first support bar (710) and the second support bar (720) positioned therebetween. Unnecessary interference can be eliminated by displacing the rail portions (510, 610) as guide structures outside the flat portions (520, 620) of each rail. Within the limits where such an action is possible, the shape, size, angle, etc. of the rail portions (510, 610) can be modified as needed, and thus need not be limited to the drawings.

[0125] The first slide block (740) and the second slide block (730) are formed in a structure that is more effectively coupled to the rail portions (510, 610) that are extended outwardly from the flat portions (520, 620). The first slide block (740) and the second slide block (730) may each include a pair of holders (733, 743) that have guide holes (731, 741) formed on the inside through which the rail portions (510, 610) pass and extend outwardly from the rail portions (510, 610) to surround and couple the rail portions (510, 610) from the outside of the rail portions.

[0126] Holders (733, 743) formed on the slide blocks can be connected by, for example, fixed brackets (734, 744). The fixed brackets (734, 744) can be formed integrally with the holders and can serve as the body of each slide block. An axis (see 730a, 740a of Fig. 13(a)) that rotatably connects a support bar connected to each slide block can also be formed on the fixed brackets. The first slide block (740) and the second slide block (730) of this type can be slidably connected to the rail portions (610, 510) formed on the upper rail (60) and the lower rail (50), respectively.

[0127] Referring to the enlarged view of Fig. 13(b), a friction adjusting ring (732, 742) may be arranged on the inner surface of the guide hole (731, 741) of each slide block, which is interposed between the rail portion (510, 610) and the guide hole (731, 741) to adjust the friction generated between the rail portion (510, 610) and the guide hole (731, 741). The friction adjusting ring (732, 742) is arranged in close contact with the inner surface of the guide hole (731, 741).

[0128] The inner surface of the friction adjustment ring (732, 742) may be formed with a contact surface that protrudes and makes contact with the rail portion (510, 610), and a non-contact surface that is retracted and does not make contact with the rail portion (510, 610). That is, the contact surface and the non-contact surface repeatedly form a rough structure, so that the frictional heat generated in the rail portion (510, 610) can be dissipated through the non-contact surface. In addition, since the frictional force can be increased or decreased by adjusting the area ratio of the contact surface and the non-contact surface, the moving speed of each slide block can be appropriately adjusted using the friction adjustment ring. With this structure, it is possible to eliminate the frictional heat generated during sliding movement between each slide block (first slide block and second slide block) and the rail (upper rail and lower rail), and to appropriately adjust the size of the frictional force.

[0129] In this manner, a robust and stable rooftop tent can be realized. Furthermore, as previously described, in an emergency, a rotating handle (see 900 in FIG. 11) can be attached to the drive cylinder (see 800 in FIG. 11) (via an extension rod) for manual operation. In normal times, the rooftop tent can be realized as a highly versatile tent capable of automatic operation by a motor. Therefore, the present invention can be installed on a vehicle and used effectively outdoors.

[0130] Hereinafter, a camping car to which the rooftop tent of the present invention is applied will be described in more detail with reference to FIG. 14.

[0131] Fig. 14 is a conceptual diagram of a camping car according to one embodiment of the present invention.

[0132] Referring to Fig. 14, the camping car (2) according to the present invention includes the rooftop tent (1) (hereinafter, “rooftop tent”) capable of emergency operation as described above. The rooftop tent (1) is installed on the roof of the vehicle body (2a). That is, the camping car (2) can be configured to include the rooftop tent (1) described above and the vehicle body (2a) on which the rooftop tent (1) is installed on the roof. The vehicle body (2a) of the camping car (2) can be modified into various shapes, and the size and length of the rooftop tent can also be changed accordingly depending on the size and length of the vehicle body.

[0133] The rooftop tent (1) can be opened in a pop-up manner from the vehicle roof. That is, the rooftop tent (1) is folded in a state of close contact with the roof of the camping car (2) in the manner of the aforementioned FIG. 4 [see (d) of FIG. 4], and then, as shown in FIG. 14, the tent cover (10) is raised upwards by operating the scissor lifts (71, 72), allowing the tent to be easily installed in a pop-up manner. Although the tent is shown in an inserted state in the drawing, the aforementioned sliding deck can be pulled out to expand the space if necessary. Matters related to the sliding deck will be described in more detail in another embodiment of the present invention.

[0134] The rooftop tent (1) can be opened and closed by automatically and / or manually operating the drive cylinder (800) as described above. That is, in normal times, if there are no problems, the drive motor (see 804 of FIG. 11) can be operated to automatically extend and contract the drive cylinder (800) to open and close the rooftop tent (1). In addition, even in an emergency situation where automatic operation is difficult (e.g., power loss due to battery discharge), the rooftop tent (1) can be opened and closed by manually operating the drive cylinder (800) by combining the rotary handle (900), so that it can effectively respond even in an emergency.

[0135] Fig. 14 illustrates the manual operation of such a rooftop tent (1). That is, in an emergency, the user can support the rotating handle (900) on the vehicle body (2a) by connecting the horizontally arranged driving cylinder (800) to the extension rod (806) and rotate it stably. That is, as described above, the driving cylinder (800) is installed parallel to the lower rail (50) and is fixed in the horizontal direction, so that when the rotating handle is connected, the screw rod (see 803 in Fig. 11), the extension rod (see 806 in Fig. 11), and the outer rod (see 901 in Fig. 11) of the rotating handle (900) can be supported on the same axis parallel to the vehicle body and rotated easily. As previously explained, if the drive cylinder has a different arrangement (e.g., connected at an angle between the lower rail and the second support bar) that changes angle as the scissor lift is raised or lowered, the cylinder continues to move as the scissor lift is operated, making such manual operation difficult. The present invention has the advantage of not only making the scissor lift easy to operate by installing the drive cylinder horizontally on the lower rail, but also making manual operation extremely convenient.

[0136] In addition, the rooftop tent (1) is sturdy because all of the shielding structures, such as the side folding plates (30), tent cover (10), and base plate (20), as described above, can be configured in the form of a hard cover, and it also has excellent soundproofing and waterproofing functions due to its watertight structure. Therefore, you can rest more comfortably inside the camping car (2).

[0137] The rooftop tent (1) can be entered and exited through various routes. For example, it is possible to enter and exit the tent by forming an opening (not shown) in the roof of the camping car (2), and as described above, it is also possible to enter and exit from the outside of the vehicle by using a movable ladder (see 220 in FIG. 1) installed on the sliding deck (see 210 in FIG. 1). However, if the sliding deck is formed, entry and exit through the vehicle roof may be difficult due to the internal structure of the base plate, so it may be convenient to use a ladder structure (movable ladder) installed on the sliding deck.

[0138] If necessary, a reinforcing member (2b) may be installed on the upper part of the body (2a). The reinforcing member (2b) can be installed in areas where the tent and the body are separated by the curved surface of the body (2a). The reinforcing member (2b) can also serve to secure the base plate and reduce air resistance by forming a streamlined outer surface.

[0139] In this manner, a camping car (2) including a rooftop tent (1) of the present invention can be formed. The camping car (2) is convenient because the tent can be opened up and used immediately from the roof in a pop-up manner, and space can also be expanded by applying a sliding deck. Furthermore, since both automatic and / or manual operation are possible, it can effectively respond to problems that may arise outdoors. A camping car (2) having this structure can be implemented using the rooftop tent (1) of the present invention.

[0140] Hereinafter, with reference to FIGS. 16 to 21, a rooftop tent capable of emergency operation and a camper van including the same according to another embodiment of the present invention will be described in detail. Since this other embodiment of the present invention features an access structure via a sliding deck and an automatic door locking method, repeated descriptions of the aforementioned details will be omitted, and the differences will be described with emphasis. Any portions not described separately can be understood based on the description of the previous embodiment.

[0141] Fig. 15 is a perspective view of a rooftop tent capable of emergency operation according to another embodiment of the present invention.

[0142] Referring to FIG. 15, a rooftop tent (1-1) capable of emergency operation according to another embodiment of the present invention (hereinafter, “rooftop tent”) further includes a sliding deck (210) inserted into the interior of a base plate (20) or entering and exiting from the side of the base plate (20), an access hole (210a) formed through the sliding deck (210), and a movable ladder (220) movably installed on the sliding deck (210). Since the position of the movable ladder (220) is adjusted as shown in FIG. 18, the movable ladder can be moved to an accessible position in the access hole and entry and exit can be made through the access hole.

[0143] However, since there is a risk of falling if the access hole (210a) is always open, a door (211) may be applied together. In this embodiment, the door (211) has a function that automatically locks or unlocks by changing the position of the movable ladder (220), so that it can be used more safely by opening the door only when necessary. A rooftop tent (1-1) according to another embodiment of the present invention is configured as follows.

[0144] The rooftop tent (1-1) equally includes the aforementioned tent cover (10), base plate (20), lower rail and upper rail, scissor lift part, first slide block, second slide block, driving cylinder, and rotary handle (see previous embodiment), and further includes a sliding deck (210) inserted into the interior of the base plate (20) or withdrawn to the side of the base plate (20), an access hole (210a) formed through the sliding deck (210), and a movable ladder (220) that is installed so as to be stored in the lower part of the sliding deck (210) and is mounted on a rail (see 212 of FIG. 18) that crosses the lower part of the sliding deck (210) so as to be able to change its position with the access hole (210a) therebetween.

[0145] In addition, the rooftop tent (1-1) may further include a door (211) that is opened and closed by being connected to an access hole (210a) by a hinge (2111), and a hinge locking module (211A) that locks the door (211) by inhibiting the rotation of the hinge (2111). In addition, the hinge locking module (211A) includes a catch (2112) protruding from the hinge (2111), so that when the movable ladder (220) moves toward the hinge (2111) and catches the catch (2112), the hinge (2111) can be fixed. Through this, a function of automatically locking the door can be implemented. Hereinafter, this structure will be described in more detail with reference to the drawings.

[0146] Figures 16 and 17 are drawings illustrating a door locking structure formed on a sliding deck of a rooftop tent, and Figures 18 and 19 are drawings illustrating an unlocking operation of a door formed on a sliding deck.

[0147] In the drawings above, Figures 16 and 18 illustrate the lower part of the sliding deck, and the enlarged views of Figures 17 and 19 are cross-sectional views.

[0148] Referring to FIGS. 15, 16, and 18 together, an access hole (210a) penetrating the sliding deck (210) is formed. The access hole (210a) may be formed by opening a portion of the sliding deck to a size that allows a person to pass through. The access hole functions as a passageway for entering and exiting the tent, and within such a limit, its shape is not limited, and thus, it may be modified into a shape other than that shown in the example.

[0149] A movable ladder (220) is installed in the sliding deck (210) together with an access hole (210a). The movable ladder (220) is mounted on a rail (212) that crosses the lower part of the sliding deck (210) and can be moved around with the access hole (210a) in between (see FIG. 18). Accordingly, the movable ladder (220) can be moved to enter and exit the access hole (210a) (see FIG. 21), or the movable ladder can be placed outside the sliding deck and can be entered and exited outside the sliding deck (210) rather than through the access hole (210a) (see FIG. 20).

[0150] Referring to Fig. 16, the movable ladder (220) is slidably connected to a rail (212) that crosses the lower portion of the sliding deck (210). The rails (212) are arranged in pairs to cross the lower portion of the sliding deck with an access hole (210a) therebetween, and the movable ladder (220) can be inserted between the rails (212) and moved along the rails (212). In the present embodiment, the rails (212) are arranged in a direction that matches the withdrawal direction of the sliding deck (210), but if necessary, the rails (212) can also be installed in a direction that intersects the withdrawal direction of the sliding deck (210). However, in any case, since the rail (212) is arranged across the lower part of the sliding deck (210), the movable ladder (220) mounted on the rail (212) can reach the access hole (210a) along the rail (212) or pass through the access hole (210a) to move to the end of the sliding deck (210).

[0151] The movable ladder (220) may be formed to be foldable. For example, the movable ladder (220) may include a pair of frame bars (223) that are foldable in the longitudinal direction, and a plurality of step pads (224) that are foldable and installed between the frame bars (223). The step pads (224) are formed to be foldable, for example, in a rotational manner, so that they can be easily stored between the frame bars (223) when the frame bars (223) are folded. Accordingly, the movable ladder (220) can be folded in the longitudinal direction to be reduced and then stored under the sliding deck (210). The structure of the movable ladder (220) will be described in more detail later.

[0152] As described above, a variable support member (214) capable of being stored may also be installed at the bottom of the sliding deck (210). The variable support member (214) is hinged to the sliding deck (210) so that it can be unfolded downward (see FIG. 15), and when unfolded, it can be extended lengthwise to support the floor (see FIG. 20). Therefore, when the sliding deck (210) is withdrawn, the variable support member (214) can support the floor, allowing for a more stable tent installation. The shape, structure, number, etc. of the variable support member (214) may be changed within such limits.

[0153] Referring to Fig. 15, a door (211) is installed to open and close an access hole (210a). The door (211) can be connected to the access hole (210a) using a hinge (2111). The hinge (2111) can be installed at an end facing the outside of the sliding deck of the access hole (210a) and can be fixed to the sliding deck (210). The door (211) is connected to the access hole (210a) by the hinge (2111) to be opened and closed.

[0154] Since the door (211) is connected by a hinge (2111), it can be opened only when the hinge (2111) rotates. Therefore, a hinge locking module (211A) that locks the door (211) by suppressing the rotation of the hinge (2111) may be considered. Referring to the enlarged view of Fig. 15, the hinge locking module (211A) includes a catch (2112) protruding from the hinge (2111), so that when the movable ladder (220) moves toward the hinge (2111) and catches on the catch (2112), the hinge (2111) can be fixed. In Fig. 15, the movable ladder (220) is positioned in an overlapping state under the catch (2112), so that the door is locked.

[0155] The catch (2112) may be a kind of rotation-preventing projection protruding from the hinge (2111). Since the hinge (2111) has a shaft and a rotating part connected to the shaft (e.g., a part connected to the door around the shaft), the catch (2112) may be protruded from the rotating part of the hinge (2111) to rotate together with the hinge or to be caught on a ladder (movable ladder) to prevent rotation. In particular, since the catch (2112) extends to the outer end of the sliding deck (210) as illustrated, when the movable ladder (220) moves to the outer end of the sliding deck (210), it may overlap with the movable ladder (220) vertically (see FIG. 17). Therefore, when the catch (2112) is caught on the movable ladder (220), the rotation of the hinge (2111) is prevented.

[0156] This structure provides a function to automatically lock the door (211) by changing the position of the movable ladder (220). That is, when the movable ladder (220) is moved along the rail (330) to the position of the catch (2112) on the outside of the sliding deck (210), the catch and the movable ladder overlap (hinge rotation is suppressed), and the door (211) is locked. When the movable ladder (220) is moved to the inside of the sliding deck (210) where there is no catch (2112), the door (211) is opened (hinge rotation suppression is released). Accordingly, as shown in FIG. 15, the movable ladder (220) is placed outside the sliding deck (210) so that entry and exit can be made outside the sliding deck (210) while the door (211) is locked, and as shown in FIG. 18, the movable ladder (220) is placed inside the sliding deck (210) so that the door (211) is opened so that entry and exit can be made through the access hole (210a).

[0157] The door (211) opens and closes through the access hole (210a) of the sliding deck (210). Therefore, if it is always open, the access hole (210a) may be unnecessarily exposed, which may lead to a risk of falling accidents. However, if a structure is applied in which the door (211) opens only when necessary using a movable ladder (220), as in this embodiment, such a risk can be eliminated. Hereinafter, the locking structure and operating method of the door (211) using the movable ladder (220) and the hinge locking module (211A) will be described in more detail.

[0158] Referring to FIGS. 16 and 17, the door (211) is automatically locked when the movable ladder (220) moves to the outer end of the sliding deck (210). Since the movable ladder (220) is mounted on a rail (212) that crosses the sliding deck (210), it can be slid along the rail (212) to the outer end (end) of the sliding deck (210). As shown in Fig. 17, the catch piece (2112) extends to the outer end of the sliding deck (210), and the movable ladder (220) includes a catch bar (221) installed in a direction intersecting the catch piece (2112) at the upper end, so that when the movable ladder (220) moves to the outer end of the sliding deck (210), the catch piece (2112) and the catch bar (221) intersect, thereby inhibiting the rotation of the hinge (2111).

[0159] Referring to the enlarged view of Fig. 17, the door (211) can only be opened by rotating upward because it covers the upper portion of the access hole (210a). However, the catch (2112) protruding from the hinge (2111) to the opposite side of the door (211) intersects with the catch bar (221) of the movable ladder (220), so in the state of Fig. 17, the catch (2112) cannot rotate downward. Therefore, in the state of Fig. 17, the door (211) is locked.

[0160] That is, in order to open the door (211), the hinge (2111) must be rotated, but the catch (2112) protruding from the hinge (2111) is caught on the movable ladder (220) and prevents the rotation of the hinge (2111), so that the door (211) is locked. Therefore, in this state, it is possible to safely enter and exit the tent through the outside of the sliding deck (210) without worrying about the access hole (210a) opening (see FIG. 20).

[0161] Referring to the enlarged view of Fig. 16, the movable ladder (220) has a catch bar (221) formed at the upper end to intersect with the catch piece (2112), so that the movement of the catch piece (2112) can be easily blocked. The catch bar (221) can be installed across the frame bars (223) at the upper end of the movable ladder (220). Since the rails (212) are installed on both sides with the access hole (210a) in between and the movable ladder (220) is placed between them, the catch bar (221) placed at the upper end of the movable ladder (220) can easily overlap with the hinge (2111) of the door (211) coupled to the access hole (210a) while moving through the access hole (210a).

[0162] Accordingly, the catch bar (221) easily intersects with the catch piece (2112), which is a protrusion protruding from the hinge (2111). Preferably, the catch piece (2112) is arranged in a direction perpendicular to the catch bar (221) and is located on the movement path of the movable ladder (220) so as to easily intersect with the movable ladder (220). The hinge (2111) is installed on the upper surface of the sliding deck (210) adjacent to the access hole (210a), and the catch piece (2112) can be formed so as not to interfere with the sliding deck (210) by inserting it into a slit (2112a) opened by cutting the sliding deck (210) around the hinge (2111). As illustrated in FIG. 17, the catch piece (2112) can be arranged parallel to the sliding deck (210) when the door (211) is closed.

[0163] The movable ladder (220) may also include a sliding hinge portion (222). The sliding hinge portion (222) is a bar that functions as a hinge axis and is located at the upper end of the movable ladder (220) and is slidably connected to the rail (212) while also functioning as a rotation axis of the movable ladder (220). For example, the sliding hinge portion (222) may be formed as a cylindrical bar that is concentrically connected to a catch bar (221) and has an end that protrudes outward from the frame bar and is rotatably connected to the rail (212). For example, as shown in FIG. 16, the sliding hinge portion (222) may be formed in a structure in which it is arranged concentrically with the catch bar (221) and has an end that protrudes outward and is connected to the rail (212). Due to this fastening structure, the movable ladder (220) can be easily moved along the rail (212) and can also be folded by rotating the top around an axis (see Fig. 2).

[0164] Referring to FIGS. 18 and 19, when the movable ladder (220) is moved along the rail (212) toward the inside of the sliding deck (210), the overlap between the catch (2112) and the movable ladder (220) is released, allowing the door (211) to be easily opened. That is, as shown in FIG. 18, when the movable ladder (220) is positioned toward the inside of the sliding deck (210) through the access hole (210a), the interference of the catch (2112) is eliminated, allowing the door (211) to be easily rotated downward, allowing the door to be easily opened upward. Therefore, when the position of the movable ladder (220) is changed so that the connection between the catch (2112) and the movable ladder (220) (or the catch bar of the movable ladder) is released, the door (211) can be converted to an openable state.

[0165] This operation is more clearly shown in the enlarged view of Fig. 19. The movable ladder (220) can be moved along the rail (212) to get out of the catch (2112) and be positioned at the opposite end (the side without the hinge) of the access hole (210a). At this time, it is also possible to fix the movable ladder at a desired position by installing a fixing device (not shown) or a locking device that can fix the movable ladder at a specific position on the rail. In this state, the catch (2112) and the movable ladder (220) are completely separated, so that the catch (2112) cannot restrain the rotation of the hinge (2111), and when the door (211) is opened to enter and exit through the access hole (210a), the catch (2112) rotates to the opposite side of the door, allowing the door (211) to be easily opened.

[0166] In this state, since the door (211) can be opened without any problem because the door is entered through the movable ladder (220) to the access hole (210a), the door (211) can be closed after entering the upper part of the sliding deck (210) through the access hole (210a). After passing through the access hole, if the position of the movable ladder (220) is moved to the outer end of the sliding deck (210), the door (211) can be locked again as described above.

[0167] Figures 20 and 21 are conceptual diagrams of a camping car according to another embodiment of the present invention.

[0168] Accordingly, the present invention allows the movable ladder (220) to be moved outside the sliding deck (210) as shown in FIG. 20, and allows entry and exit to the outside of the sliding deck (210) through the movable ladder (220) (at this time, the door is in a locked state, so entry and exit is safe). As shown in FIG. 21, the movable ladder (220) is moved inside the sliding deck (210), and allows entry and exit to the inside of the sliding deck (210) through the access hole (210a) (at this time, the door is in an open state, so entry and exit is safe through the access hole).

[0169] In particular, when applying an expansion module (140) that shields the upper part of the sliding deck (210) as in FIG. 21, since the tent space is extended to the sliding deck, you can enter and exit the tent without getting wet even in the rain by entering and exiting through the access hole (210a) inside the sliding deck (210). The expansion module (140) extends from the tent cover (10) and the side structure (the aforementioned side folding plate, side rotating plate, etc.) toward the sliding deck (210) and can be formed into a shielding structure that is easy to fold or unfold, such as fabric. If necessary, it is also possible to configure it by adding a sliding panel or a folding panel that is pulled out to the side of the tent cover (10), so there is no need to have a limited understanding of the form of the expansion module.

[0170] A foldable railing module (150) can also be installed on the upper surface of the sliding deck (210), so that the railing module (150) can be unfolded to prevent people from falling. The railing module (150) and the expansion module (140) are not limited in structure, so they are conceptually depicted in the drawing.

[0171] After safely enjoying camping by installing the rooftop tent (1-1) in this manner, the tent can be folded and moved as in the embodiment described above (see FIGS. 3 and 4). The rooftop tent (1-1) can be installed on the roof of the camping car (2) using the vehicle body in the same manner as in the embodiment described above, and can be conveniently used by folding or unfolding it while fixed to the camping car (2). Furthermore, if an entrance structure is formed on the inside of the sliding deck as in this embodiment, the expanded tent can be entered and exited in various ways and used more effectively. In addition, in this embodiment as described above, the tent can be manually operated in an emergency using the rotary handle (see 900 in FIG. 15), so that preparation for emergency situations is also possible. A rooftop tent like this can be configured, installed, and used on a vehicle.

[0172] Although the embodiments of the present invention have been described with reference to the attached drawings, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without altering the technical concept or essential features thereof. Therefore, the embodiments described above should be understood to be illustrative in all respects and not restrictive.
