DETAILED DESCRIPTION

[0030] The following further describes the embodiments of the present application in conjunction with the accompanying drawings. The same or similar reference numerals in the accompanying drawings represent the same or similar elements or elements with the same or similar functions.

[0031] In addition, the embodiments of the present application described below in conjunction with the drawings are exemplary and are only used to explain the embodiments of the present application and should not be construed as limiting the present application.

[0032] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0033] A yurt is a type of house inhabited by Mongolian herdsmen, also known as a yurt, a felt tent or a felt tent. It is a practical residence created by the Mongolian people during their long-term nomadic life of following water. A yurt uses a special wooden frame as a "hana" (the fence support of the yurt), which is wrapped with two to three layers of wool felt on the outside and then tied with ropes twisted from horsehair or camel hair. The top of the yurt uses "unai" (the top felt of the yurt) as a support and is covered with "bules" (the surrounding felt on the yurt), forming a canopy. The yurt is very convenient to build and move, and is easy to set up, disassemble and move, making it suitable for animal husbandry production and nomadic life.

[0034] A yurt is a prefabricated building, and the bottom of the yurt is usually suspended. However, the suspended bottom makes it inconvenient to enter and exit the yurt. In the related art, a ladder is usually installed at the door. However, if the ladder is fixed on the yurt, the installation position of the ladder is likely to hinder the normal work of the user. If a detachable ladder is set up, the ladder needs to be moved every time entering and exiting, which is extremely inconvenient. In addition, since the space in a yurt is usually small, it is difficult to free up extra space for storing the ladder.

[0035] See also Figure 1 The yurt 100 of the implementation mode of the present application includes a main body 10, the main body 10 includes a side wall 11 and a bottom plate 12, the bottom plate 12 is arranged overhead, the side wall 11 is provided with a door opening, the entry and exit device 20 includes a door panel 21 and a telescopic ladder 22, the door panel 21 is arranged on the side wall 11, and the door panel 21 is used to open or close the door opening; the telescopic ladder 22 is arranged on the bottom plate 12 of the yurt 100 corresponding to the door opening, and the telescopic ladder 22 is configured that when the door panel 21 is opened, the telescopic ladder 22 extends out to connect the bottom plate 12 and the ground, and when the door panel 21 is closed, the telescopic ladder 22 is retracted and stored on the bottom plate 12.

[0036] The entry and exit device 20 proposed in the embodiment of the present application links the telescopic ladder 22 and the door panel 21. When the door is opened, the telescopic ladder 22 automatically extends for use by the user, and when the door is closed, the telescopic ladder 22 automatically retracts, thereby effectively reducing the complexity of operation and greatly improving the convenience of entry and exit of the yurt 100. Moreover, compared with traditional ladders, the telescopic ladder 22 occupies less space when retracted. At the same time, the automatic retraction of the telescopic ladder 22 after the door is closed can avoid obstruction and reduce the wind-exposed area of ​​the yurt 100, which is beneficial to improving the stability of the yurt 100.

[0037] Specifically, the yurt 100 includes a main body 10 and a roof 30 . The roof 30 is located above the main body 10 . The main body 10 and the roof 30 can be manufactured as one piece or separately and then assembled.

[0038] The roof 30 of the yurt 100 is usually in a cone shape. The cone structure has excellent stability. Its cross section is a triangle. As a solid figure, the triangle is not easy to deform. Secondly, the cone structure is conducive to the sliding of rain and snow. Since the top of the yurt 100 has a certain inclination, when it rains or snows, the rain and snow can slide down along the slope and will not accumulate on the yurt 100, thereby avoiding the problem of roof leakage. In addition, since strong winds are a common natural phenomenon on the grassland, the cone design can make the wind blow quickly, effectively reducing the impact damage of the strong wind on the yurt 100.

[0039] The main body 10 of the yurt 100 is generally cylindrical. First, from the perspective of structural stability, the cylindrical structure has excellent support and stability. This design can effectively resist the impact of external wind and other natural forces, ensuring that the yurt 100 can stand firmly in harsh natural environments.

[0040] Secondly, the cylindrical design helps to maximize the living area. When the circumference is equal, the circle has the largest area. Therefore, designing the bottom of the yurt 100 into a circle can obtain the maximum living space with limited materials, thereby meeting the living needs of nomads.

[0041] In addition, the cylindrical design also has certain wind and snow resistance. On the grassland, wind and snow pressure are common natural phenomena. The cylindrical structure can effectively reduce the direct impact of wind and snow on the yurt 100, protecting the safety and comfort of the residents.

[0042] Finally, the cylindrical design also reflects the full utilization and conservation of materials. Nomads need to carry yurts during migration, so lightness and ease of carrying are very important. The cylindrical design can minimize the use of materials while ensuring structural stability, facilitating the migration of nomads.

[0043] The chassis is an important part of the yurt 100, providing a stable support and a solid foundation for the yurt 100. In the related art, the shape of the chassis of the yurt 100 is matched with the main body 10, and is usually circular. The diameter and height of the chassis vary according to the size and purpose of the yurt 100. The chassis is usually constructed of durable materials.

[0044] The chassis not only provides a stable support for the yurt 100, but also prevents the yurt 100 from swaying or falling in the wind. In addition, the chassis can also disperse the weight of the yurt 100, reduce the pressure on the ground, and thus protect the ecological environment of the ground.

[0045] The chassis of the Yurt 100 is relatively easy to set up and dismantle, usually without the need for complex tools and skills. When the Yurt 100 needs to be moved or relocated, the chassis can be easily disassembled and carried to the new location for reconstruction.

[0046] In other embodiments, the chassis of the yurt 100 does not need to be disassembled and can be directly moved with the yurt 100 as a whole.

[0047] The yurt 100 is usually provided with supporting feet 40 under the chassis, and the supporting feet 40 lift the main body 10 off the ground. Specifically, first, the supporting feet 40 are used to isolate the yurt 100 from the ground, which helps to prevent moisture from the ground from penetrating into the yurt 100. Especially in humid or rainy areas, this design can effectively keep the inside of the yurt 100 dry, prevent items from getting wet, and provide a more comfortable living environment for the residents.

[0048] Second, raising the yurt 100 can increase the distance between it and the ground, which helps air circulation and improves ventilation. Especially in the hot summer, this design can make the air inside the yurt 100 more circulated, reduce the accumulation of heat, and provide a cooler environment for the occupants.

[0049] Third, by lifting the yurt 100 through the support legs 40, the possibility of insects, small animals, etc. on the ground entering the yurt 100 can be reduced. This helps to protect the safety and health of the residents, and also maintains the cleanliness and sanitation of the internal environment of the yurt 100.

[0050] Fourth, as a form of residence for nomadic people, the yurt 100 needs to adapt to different terrains and ground conditions. The design of the support legs 40 allows the yurt 100 to be easily placed on various grounds, whether it is grass, sand or uneven ground, and can maintain its stability and comfort.

[0051] Since the chassis is suspended by the support legs 40, a ladder is usually provided at the door opening of the yurt 100 for easy access. The ladder plays a vital role in the use and life of the yurt 100 and is the main passage for entering and exiting the yurt 100. Since the yurt 100 is usually round and the ground is at a certain height from the top of the yurt, the ladder becomes the main way to enter and exit the yurt 100. One end of the ladder is fixed to the bottom of the yurt 100, and the other end extends to the vicinity of the top of the yurt, so that the occupants can enter and exit the yurt 100 safely and conveniently.

[0052] In this embodiment, the ladder is a telescopic ladder 22. The telescopic ladder 22 refers to a ladder that can be stretched and shortened like a fishing rod, and is mainly divided into an engineering telescopic ladder 22, a bamboo telescopic ladder 22, a folding telescopic ladder 22, and the like.

[0053] The door panel 21 is an important part of the yurt 100 and is usually made of wood. From a structural point of view, the door panel 21 is laterally fixed to the Khana (the wall of the yurt 100) during the construction process, so it can be regarded as a deformed Khana, providing stable support for the yurt 100. The height of the door panel 21 is usually low, in order to maintain the overall structure and stability of the yurt 100. In addition, the door panel 21 of the yurt 100 not only has practical functions, but also has decorative effects.

[0054] In this embodiment, the yurt 100 is provided with one door opening and a door panel 21 for opening or closing the door opening. In other embodiments, one door opening may also be provided with two door panels 21, which are arranged opposite to each other and can be opened individually or in full when in use.

[0055] In other embodiments, the number of the door panels 21 can also be set to multiple, and the number of door openings is the same as the door panels 21, and the door openings and door panels 21 are arranged one by one. In this case, a telescopic ladder 22 is required to be provided at the edge of the bottom plate 12 under each door opening.

[0056] See also Figure 1 In some embodiments, the door panel 21 is slidably disposed on the side wall 11 and is configured to slide between a first position for closing the door opening and a second position for opening the door opening.

[0057] Thus, compared with other forms of opening and closing door panels 21, the sliding door panels 21 occupy less space when sliding, which is beneficial for saving space for the yurt 100 and improving space utilization.

[0058] Specifically, the door panel 21 and the side wall 11 are connected in a sliding manner, and the door panel 21 can be slidably set along the vertical direction, the direction of the side wall 11 or any other direction. In this embodiment, the door panel 21 is slidably set along the direction of the side wall 11, and a sliding groove for the sliding of the door panel 21 is provided on the side wall 11.

[0059] When the door panel 21 is in the first position, the door panel 21 completely covers the door opening, so that the door opening is completely closed. When the door panel 21 is in the second position, the door panel 21 is located at one side of the door opening, and the door opening is open. Further, the first position and the second position are respectively located at two ends of the slide slot.

[0060] In other embodiments, the door panel 21 may also be hinged to the side wall 11. Specifically, the yurt 100 further includes a hinge, and the hinge includes two connecting parts. One connecting part of the hinge is installed at one edge of the door panel 21 through a fastener, and the other connecting part is installed at the edge of the side wall 11 closest to the hinge through a fastener. Optionally, the hinge may be a spring hinge or a glass hinge. When a larger opening angle is required, the hinge may also be a special-shaped hinge.

[0061] In other embodiments, the door panel 21 may also be rotatably connected to the side wall 11. In this case, a rotating shaft for rotating the door panel 21 is required, and the rotating shaft may be vertically arranged on the door panel 21 or at both ends. One end of the rotating shaft is connected to the side wall 11, and the other end of the rotating shaft is connected to the side wall 11 or the bottom plate 12. Alternatively, the rotating shaft may be horizontally arranged at both ends of the door panel 21, and in this case, the two ends of the rotating shaft are respectively connected to the side walls 11 on both sides of the door opening.

[0062] In some embodiments, the access device 20 further includes a first driving assembly, which is disposed on the main body 10 and is used to drive the door panel 21 to open or close the door opening.

[0063] In this way, the door panel 21 is driven by the first driving assembly, which effectively reduces the operating difficulty of the user and facilitates linkage with the telescopic ladder 22.

[0064] Specifically, in the present embodiment, since the door panel 21 slides along the edge of the side wall 11, its motion trajectory is not a straight line. Therefore, the linear drive component is difficult to directly apply. The first drive component may be a motor and a gear set. The motor drives the gear set to drive the door panel 21 to slide, or the motor drives a chain drive or a belt drive to drive the door panel 21 to slide.

[0065] In other embodiments, the sliding track of the door panel 21 may also be set as a straight line. In this case, the first driving member may be set as a traditional linear driving component, such as a linear motor, a ball screw assembly, a cylinder or a hydraulic cylinder.

[0066] In some embodiments, the telescopic ladder 22 has a fixed end and a movable end, and the fixed end is fixed to the edge of the bottom plate 12 near the door opening.

[0067] In this way, after the telescopic ladder 22 is retracted, it will not cause any obstruction to the people around, and at the same time, the space occupied by the telescopic ladder 22 can be reduced.

[0068] Specifically, the fixed end refers to the end whose position remains unchanged or changes within a small range when the telescopic ladder 22 is extended or retracted, and the movable end refers to the end that is extended to the outside of the bottom plate 12 when the telescopic ladder 22 is extended and is retracted to the inside of the bottom plate 12 when retracted. The movable end usually has a pedal 222.

[0069] See also Figure 2 In some embodiments, the access device 20 further includes a storage cabin 23 , which is disposed below the bottom plate 12 , and the telescopic ladder 22 is retracted and stored in the storage cabin 23 .

[0070] In this way, a storage cabin 23 is provided under the bottom plate 12, which utilizes the useless area under the bottom plate 12, solves the storage problem of the telescopic ladder 22, avoids space occupation after the telescopic ladder 22 is retracted, and effectively improves the space utilization rate of the yurt 100.

[0071] It is easy to understand that there is usually a certain space under the bottom plate 12 due to the support legs 40 being suspended, and the space here is usually not used. At this time, the storage cabin 23 is arranged under the bottom plate 12, which not only solves the storage problem of the telescopic ladder 22, but also improves the storage capacity of the yurt 100.

[0072] Specifically, the edge of the floor near the door opening is recessed inward to form a storage compartment 23, and the storage compartment 23 and the bottom plate 12 are an integrated structure formed by integral processing.

[0073] In other embodiments, the storage compartment 23 may also be an independent structure that is processed separately, and the storage compartment 23 is installed below the bottom plate 12 near the edge of the door opening through fasteners.

[0074] Furthermore, multiple storage compartments 23 can be provided, and the multiple storage compartments 23 are all provided under the chassis. The storage compartment 23 located near the door opening is used to store the telescopic ladder 22, and the storage compartments 23 located at other positions can also be used to store other items, thereby further improving the storage capacity of the yurt 100.

[0075] See also Figure 2 In some embodiments, the storage compartment 23 is formed with an opening for the telescopic ladder 22 to enter and exit, and the storage compartment 23 includes a storage compartment door 231, which is used to open or close the opening.

[0076] In this way, when the telescopic ladder 22 is in the retracted state, the storage hatch 231 can protect the telescopic ladder 22 and effectively isolate it from external moisture, dust, etc., to prevent the telescopic ladder 22 from rusting due to moisture or getting stuck due to dust, which is beneficial to improving the service life of the telescopic ladder 22.

[0077] Specifically, the storage hatch 231 is rotatably disposed at the opening of the storage cabin 23. A rotation shaft is disposed at the rear of the storage hatch 231, and the rotation shaft passes through the rear of the storage hatch 231, and the two ends of the rotation shaft are respectively connected to the two opposite side walls 11 of the storage cabin 23. The storage hatch 231 is an integrated structure formed by integral processing. In order to enhance the protection effect of the telescopic ladder 22, the storage hatch 231 can be made of metal. Optionally, the storage hatch 231 can be made of aluminum, iron, steel and other materials.

[0078] Furthermore, a limiting support portion 2311 is provided on the storage hatch 231. The limiting support portion 2311 is used to limit the opening angle of the storage hatch 231 to prevent it from hitting the ground and causing damage to the storage hatch 231. At the same time, the limiting support portion 2311 can also support the storage hatch 231 to prevent the storage hatch 231 from being accidentally closed due to external force, thereby affecting the use of the telescopic ladder 22, and even causing damage or jamming.

[0079] Furthermore, a sealing gasket may be provided at the position where the storage door 231 contacts the storage compartment 23. First, the sealing gasket may provide a buffer when the storage door 231 is closed. Second, the sealing gasket may be provided between the storage door 231 and the storage compartment 23 to further prevent moisture and dust in the air from entering the storage compartment 23, thereby affecting the telescopic ladder 22 inside.

[0080] In other embodiments, the storage hatch 231 and the bottom plate 12 may also be connected by a hinge, and the hinge includes two connecting parts, wherein one connecting part of the hinge is installed at the tail of the storage hatch 231 through a fastener, and the other connecting part is installed at the edge of the bottom plate 12 near the tail of the storage hatch 231 through a fastener.

[0081] In other embodiments, the storage hatch 231 and the bottom plate 12 may also be slidably connected. In this case, the storage hatch 231 may be configured as a rolling door, and guide rails for the storage hatch 231 to slide are provided at the edges of the two side walls 11 of the storage cabin 23.

[0082] In some embodiments, the storage hatch 231 is configured to open when the door panel 21 is open, and to close when the door panel 21 is closed.

[0083] In this way, the placement and recovery of the telescopic ladder 22 can be achieved by only controlling the opening and closing of the door panel 21 without performing other controls, which is conducive to simplifying the operating difficulty of the access device 20 and improving the user's experience.

[0084] Specifically, when the door panel 21 is open, someone needs to go in or out, the storage cabin door 231 is opened first, and the telescopic ladder 22 extends from the storage cabin 23. Since the telescopic ladder 22 is extended at this time, the storage cabin door 231 cannot be closed, so it needs to be kept open. When the door panel 21 is closed, it means that no one needs to go in or out at this time, and the telescopic ladder 22 is retracted first. After the telescopic ladder 22 is retracted, the storage cabin door 231 is closed, thereby sealing the storage cabin 23 to protect the telescopic ladder 22.

[0085] Furthermore, a third driving assembly is provided in the storage cabin 23, the third driving assembly matches the storage cabin door 231, and the third driving assembly is used to drive the opening and closing of the storage cabin door 231. In this embodiment, the third driving assembly can be a rotary cylinder, and the rotary cylinder drives the storage cabin door 231 to rotate to realize the opening and closing of the storage cabin door 231.

[0086] See also Figure 3 In some embodiments, the telescopic ladder 22 includes a pedal 222 and two telescopic frames 221 . The telescopic frames 221 can be unfolded or folded. The two telescopic frames 221 are arranged in parallel, and the pedal 222 is connected between the two telescopic frames 221 .

[0087] Thus, the telescopic ladder 22 has a simple structure, is easy to manufacture, and is also easy to install and maintain.

[0088] Specifically, in this embodiment, the telescopic ladder 22 is a folding telescopic ladder 22, and the telescopic frame 221 includes a first support frame 2211, a second support frame 2212, a third support frame 2213, a first connecting frame 2214, a second connecting frame 2215 and a driving frame 2216. One end of the first connecting frame 2214 is rotatably connected to one end of the first support frame 2211. One end of the third support frame 2213 is rotatably connected to the other end of the first connecting frame 2214. One end of the second support frame 2212 is rotatably connected to the end of the driving frame 2216. The other end of the second support frame 2212 is rotatably connected to one end of the second connecting frame 2215. The middle part of the first connecting frame 2214 is rotatably connected to the middle part of the second support frame 2212. One end of the second connecting frame 2215 away from the second support frame 2212 is rotatably connected to the middle part of the third support frame 2213. The first support frame 2211 is rotatably connected to the middle part of the driving frame 2216.

[0089] Each telescopic ladder 22 has two telescopic frames 221. The first support frames 2211 of the two telescopic frames 221 are respectively connected to the two ends of a pedal 222. The second support frames 2212 of the two telescopic frames 221 are respectively connected to the two ends of the second pedal 222. The third support frames 2213 of the two telescopic frames 221 are respectively connected to the two ends of the third pedal 222.

[0090] One end of the driving frame 2216 away from the second supporting frame 2212 is rotatably disposed on the side wall of the storage compartment 23. One end of the first supporting frame 2211 away from the first connecting frame 2214 is slidably disposed on the side wall of the storage compartment 23 in a horizontal direction.
