Abstract
Description
Technical Field
[0001] This utility model belongs to the field of hidden door technology, specifically relating to a sliding hidden door for RVs. Background Technology
[0002] A sliding hidden door for motorhomes is a type of door designed for use inside motorhomes. It typically opens by sliding rather than a traditional revolving door. Its main advantage is space saving, as the door does not take up extra space when open, making it suitable for compact environments such as motorhomes, mobile homes, or small apartments.
[0003] Chinese patent publication number CN212047094U discloses a hidden sliding door for RVs. The patent includes an RV body with a mounting bracket welded to its front outer wall. The mounting bracket includes a storage cabinet and a frame. The frame is bolted to one outer wall of the storage cabinet. A second sliding groove is formed on one outer wall of the storage cabinet. A first sliding groove is formed on both the bottom and top inner walls of the frame, and a sliding door is slidably connected to both the first and second sliding grooves. Rubber pads are adhered to the inside of both the first and second sliding grooves. A door handle is bolted to one outer wall of the back of the sliding door. This patent reduces the impact of the sliding door on other objects when the RV is in motion, preventing damage from collisions and extending the door's lifespan. A locking ring can also be used to secure the sliding door while the RV is moving, minimizing swaying and reducing noise during RV movement.
[0004] Based on the above search of hidden doors, the following problems exist: The above patent can reduce the impact of the sliding door on other objects when the RV is in motion, avoid collision damage to the sliding door, and help improve the service life of the sliding door. However, it is difficult to restrict the door when it is open, which can easily cause the door to close accidentally when it is opened, resulting in danger. Therefore, we propose a hidden door with a sliding structure for RVs. Utility Model Content
[0005] The purpose of this invention is to provide a hidden door with a sliding structure for RVs, which can solve the problem of difficulty in restricting the opening of the vehicle door in related technologies.
[0006] The specific technical solution adopted by this utility model is as follows:
[0007] A sliding hidden door for RVs includes a frame, a bottom rail fixedly installed at the bottom of the frame, a sliding door slidably installed inside the frame, a door handle fixedly installed at the front of the sliding door, and a locking device provided at the front of the frame.
[0008] The locking device includes a rotating shaft rotatably mounted on the front of the frame. A rotating ring is fixedly mounted on the circumferential surface of the rotating shaft, and a gear is fixedly mounted on the circumferential surface of the rotating shaft. A rack is slidably mounted on the front of the frame, and a fixing plate is fixedly mounted on the top of the rack. An elastic telescopic rod is fixedly mounted on the top of the fixing plate, and a limiting block is fixedly mounted on the top of the movable end of the elastic telescopic rod. When the sliding door needs to be closed, the rotating ring is manually rotated, causing the rotating shaft to rotate. The rotating shaft then causes the gear to rotate, which in turn causes the rack to move downwards. The movement of the rack causes the fixing plate to move downwards, which in turn causes the elastic telescopic rod to move downwards, and finally, the movement of the elastic telescopic rod causes the limiting block to move downwards.
[0009] The gear meshes with the rack, and this meshing ensures that the gear can drive the rack to move when it rotates.
[0010] The top of the limiting block is set as an inclined surface, which ensures that the limiting block can be pushed smoothly.
[0011] The bottom rail is equipped with a protective device, which includes a second elastic telescopic rod. The second elastic telescopic rod is fixedly installed at the front of the bottom rail. A long plate is fixedly installed at the movable end of the second elastic telescopic rod, and a baffle is fixedly installed at the top of the long plate. A sloping panel is fixedly installed on the side of the sliding door near the baffle. A fixed rod is fixedly installed at the bottom of the sloping panel, and a push plate is fixedly installed at the bottom of the fixed rod. When the sliding door moves and closes, it causes the sloping panel to move. The moving sloping panel contacts and pushes the baffle to move. The moving baffle causes the movable end of the second elastic telescopic rod to move, opening up the space at the top of the bottom rail and no longer obstructing the movement of the sliding door. Subsequently, when the sliding door moves and closes, it causes the fixed rod to move. The moving fixed rod causes the push plate to move, and the moving push plate removes dust and other impurities that may fall into the bottom rail.
[0012] The baffle contacts the bottom rail, and the side of the inclined panel that contacts the baffle is set as an inclined surface. The contact ensures that the baffle can block the bottom rail, and the inclined surface ensures that the inclined panel can smoothly push the baffle when moving.
[0013] The push plate contacts the bottom rail, and this contact ensures that the push plate can clean the bottom rail.
[0014] The technical effects achieved by this utility model are as follows:
[0015] 1. This utility model, through the setting of a locking device, causes the limiting block to move upward and restrict the sliding door, ensuring that the sliding door will not close accidentally due to vibration, vehicle movement or external force when it is opened, effectively preventing the sliding door from closing accidentally, thereby avoiding injury to personnel or damage to the door. At the same time, it ensures that the sliding door remains stably in the required position when it is open, and will not move or close automatically due to small external forces or tilting.
[0016] 2. This utility model, through the setting of a protective device, allows the baffle to move and cover the top of the bottom track, preventing dust, sand, water droplets and other impurities from entering the bottom track. This helps to keep the bottom track clean and avoids the sliding door from sliding unevenly or getting stuck due to the accumulation of impurities, thereby extending the service life of the bottom track. The moving push plate will also remove dust and other impurities that may fall into the bottom track, ensuring that the bottom track is always clean and preventing impurities from clogging the bottom track, ensuring the smooth opening and closing of the sliding door. At the same time, it helps to reduce wear on the bottom track and prevent the bottom track from being damaged or deformed due to the accumulation of impurities. Attached Figure Description

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0025] like Figure 1-5 As shown, a sliding hidden door for a motorhome includes a frame 1, a bottom rail 2 fixedly installed at the bottom of the frame 1, a sliding door 3 slidably installed inside the frame 1, a door handle 4 fixedly installed at the front of the sliding door 3, and a locking device 5 provided at the front of the frame 1.
[0026] The locking device 5 includes a rotating shaft 51, which is rotatably mounted on the front of the frame 1. A rotating ring 52 is fixedly mounted on the circumferential surface of the rotating shaft 51, and a gear 53 is fixedly mounted on the circumferential surface of the rotating shaft 51. A rack 54 is slidably mounted on the front of the frame 1. A fixing plate 55 is fixedly mounted on the top of the rack 54. An elastic telescopic rod 56 is fixedly mounted on the top of the fixing plate 55. A limiting block 57 is fixedly mounted on the top of the movable end of the elastic telescopic rod 56. The limiting block 57 moves upward and restricts the sliding door 3, ensuring that the sliding door 3 will not close accidentally due to vibration, vehicle movement, or external force when it is opened. This effectively prevents the sliding door 3 from closing accidentally, thereby avoiding injury to personnel or damage to the door. At the same time, it ensures that the sliding door 3 is stably maintained in the required position when it is open, and will not move or close automatically due to small external forces or tilting.
[0027] Gear 53 meshes with rack 54, and the meshing ensures that gear 53 can drive rack 54 to move when it rotates.
[0028] The top of the limiting block 57 is set as a slope to ensure that the limiting block 57 can be pushed smoothly.
[0029] Working principle: First, the car door needs to be unlocked before opening. Then, the sliding door 3 is opened by pulling the door handle 4. The sliding door 3 moves into the frame 1. Then, the door handle 4 contacts and pushes the limiting block 57 to move downward. After the door handle 4 has moved, the limiting block 57 begins to move and reset under the action of the movable end of the elastic telescopic rod 56. Then, the limiting block 57 moves upward and restricts the sliding door 3, ensuring that the sliding door 3 will not close accidentally due to vibration, vehicle movement, or external force when it is open. This effectively prevents the sliding door 3 from closing accidentally, thereby avoiding personal injury or damage to the door. At the same time, it ensures that the sliding door 3... When open, the sliding door 3 remains stably in the desired position and will not automatically move or close due to small external forces or tilting. When it is necessary to close the sliding door 3, the rotating ring 52 is manually rotated. The rotation of the rotating ring 52 drives the rotating shaft 51 to start rotating. The rotation of the rotating shaft 51 drives the gear 53 to start rotating. The rotation of the gear 53 drives the rack 54 to start moving downward. The movement of the rack 54 drives the fixed plate 55 to start moving downward. The movement of the fixed plate 55 drives the elastic telescopic rod 56 to move downward. The movement of the elastic telescopic rod 56 drives the limiting block 57 to start moving downward. The downward movement of the limiting block 57 no longer restricts the door handle 4. Then, the door handle 4 is pulled to close the sliding door 3.
[0030] like Figure 1-5 As shown, a protective device 6 is installed inside the bottom rail 2. The protective device 6 includes a second elastic telescopic rod 61, which is fixedly installed at the front of the bottom rail 2. A long plate 62 is fixedly installed at the movable end of the elastic telescopic rod 61, and a baffle 63 is fixedly installed at the top of the long plate 62. A sloping panel 64 is fixedly installed on the side of the sliding door 3 near the baffle 63. A fixing rod 65 is fixedly installed at the bottom of the sloping panel 64, and a push plate 66 is fixedly installed at the bottom of the fixing rod 65. By moving the baffle 63, the top of the bottom rail 2 is blocked, preventing dust, sand, water droplets and other impurities from entering the bottom rail 2. This helps to keep the bottom rail 2 clean and avoids the sliding door 3 from sliding unsmoothly or getting stuck due to the accumulation of impurities, thereby extending the service life of the bottom rail 2.
[0031] The baffle 63 contacts the bottom rail 2, and the side of the inclined panel 64 that contacts the baffle 63 is set as an inclined surface. The contact ensures that the baffle 63 can block the bottom rail 2, and the inclined surface ensures that the inclined panel 64 can smoothly push the baffle 63 when moving.
[0032] The push plate 66 contacts the bottom rail 2, and the contact ensures that the push plate 66 can clean the bottom rail 2.
[0033] Working principle: When the sliding door 3 moves to close, it drives the inclined panel 64 to move. The inclined panel 64 contacts and pushes the baffle 63 to move. The movement of the baffle 63 drives the movable end of the elastic telescopic rod 61 to move. The movement of the baffle 63 opens the space at the top of the bottom rail 2, no longer obstructing the movement of the sliding door 3. Subsequently, the sliding door 3 moves to close, driving the fixed rod 65 to move. The movement of the fixed rod 65 drives the push plate 66 to move. The movement of the push plate 66 removes dust and other impurities that may fall into the bottom rail 2, ensuring that the bottom rail 2 is always clean and preventing impurities from obstructing the movement. The bottom rail 2 is plugged to ensure smooth opening and closing of the sliding door 3, while also helping to reduce wear on the bottom rail 2 and prevent damage or deformation of the bottom rail 2 due to the accumulation of impurities. When the sliding door 3 is opened, the inclined panel 64 no longer pushes the baffle 63. Subsequently, the baffle 63 begins to move under the action of the movable end of the elastic telescopic rod 61. The movement of the baffle 63 blocks the top of the bottom rail 2, preventing dust, sand, water droplets and other impurities from entering the bottom rail 2. This helps to keep the bottom rail 2 clean and prevents the sliding door 3 from sliding unsmoothly or getting stuck due to the accumulation of impurities, thereby extending the service life of the bottom rail 2.
[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
