Description

Technical Field

[0001] This application relates to the field of mobile home construction, and in particular to a mobile home roof. Background Technology

[0002] Prefabricated houses are widely used in construction, railway, highway, water conservancy, petroleum, commerce, tourism, and military sectors for offices, conference rooms, command posts, dormitories, warehouses, shops, rooftop additions, and various temporary housing due to their reliable structure, convenient assembly and disassembly (allowing for repeated assembly and disassembly up to ten times), aesthetically pleasing design, flexible layout, waterproof structure, light weight, long service life, low disassembly and assembly loss rate, and no construction waste generated during assembly and disassembly.

[0003] The utility model patent with application number 201320126528.4 discloses a mobile house roof, which includes a cone shape composed of four triangular tempered glass panels. The angle between each triangular tempered glass panel and the horizontal plane is 15°-30°. The lower part of the joint between adjacent triangular tempered glass panels is fixed with fasteners, and the upper part is provided with an arc-shaped cover plate. The top of the cone shape composed of the four triangular tempered glass panels is provided with an asbestos cover plate.

[0004] While the movable roof technology in dual-mode technology improves the drainage and light transmission of the house, in actual use it has been found that the strong light transmission can easily cause discomfort to users during the summer when the sunlight is intense, or during midday rest. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides a mobile home roof.

[0006] This application provides a mobile home roof, which adopts the following technical solution:

[0007] The roof of the mobile home includes an inner glass layer, which is a cone shape composed of four triangular tempered glass panels. It also includes a supporting base layer, a light-shielding outer layer, and a light-shielding adjustment mechanism that drives the outer layer to slide. The supporting base layer is fixed to the circumferential outer wall of the bottom of the inner glass layer. The outer light-shielding outer layer is slidably connected to the supporting base layer. The outer light-shielding outer layer includes four light-shielding angle plates, each corresponding to one of the four included angles of the inner glass layer. Each light-shielding angle plate includes two light-shielding plates, and the included angle between the two light-shielding plates is the same as the included angle of the corresponding inner glass layer. The light-shielding adjustment mechanism drives the light-shielding angle plates to slide along the edges of the inner glass layer.

[0008] By adopting the above technical solution, when light transmission is needed, the light-blocking adjustment mechanism drives the four light-blocking angle plates to slide down along the edges of the inner glass layer, exposing the top of the inner glass layer and thus providing better indoor lighting for user convenience. When dimmer light is needed, the light-blocking adjustment mechanism drives the four light-blocking angle plates to slide down, covering the top of the inner glass layer, while the supporting bottom layer covers the bottom perimeter of the inner glass layer, making it difficult for external light to pass through. This application solution allows the roof to have both light-blocking and light-transmitting states, providing users with convenient options; at the same time, when the supporting bottom layer and the outer light-blocking layer completely block the inner glass layer, the exposure time of the inner glass layer is reduced, thereby reducing the possibility of debris falling onto the top of the inner glass layer, keeping the inner glass layer clean and tidy, and thus maintaining good light transmission and aesthetics.

[0009] Optionally, the supporting base layer is annular, with the inner and outer ring walls of the supporting base layer parallel to the inner glass layer. The light-shielding angle plate is slidably connected to the outer wall of the supporting base layer. When the light-shielding angle plate slides to the top of the inner glass layer, the supporting base layer and the four light-shielding angle plates completely cover the outer wall of the inner glass layer. The bottom height of the light-shielding angle plate is lower than the top height of the supporting base layer.

[0010] By adopting the above technical solution, when the light-shielding angle plate slides to the top of the inner glass layer, the bottom height of the light-shielding angle plate is lower than the top height of the supporting base layer, and the light-shielding angle plate slides and connects to the outer wall of the supporting base layer. This ensures that when it rains, when the outer light-shielding layer closes the top of the inner glass layer, rainwater falls onto the outer wall of the outer light-shielding layer, then is guided to the outer wall of the supporting base layer, and finally drips from the edge of the roof. Water is less likely to contact the inner glass layer, making it less likely for water to wet the angle where the two tempered glass panels on the inner glass layer are connected. Water is also less likely to leak into the house from the angle where the two tempered glass panels are connected, giving the roof better waterproof performance. At the same time, because the light-shielding angle plate is spaced apart from the inner glass layer, it can reduce indoor rain noise during rain.

[0011] Optionally, the supporting bottom layer includes four mutually fixed supporting angle plates, each supporting angle plate including two supporting plates arranged at an angle, the ends of the two supporting plates of the same supporting angle plate being integrally formed, and the two light-shielding plates of the same light-shielding angle plate being integrally formed.

[0012] By adopting the above technical solution, the ends of the two support plates of the supporting angle plate are integrally formed, and the two light-shielding plates of the light-shielding angle plate are integrally formed, making it difficult for water to leak between the two support plates and the two light-shielding plates, making it difficult for water to flow to the joint between the two tempered glass plates, and making the roof less prone to leaks.

[0013] Optionally, the outer walls of the four edges at the top of the supporting base are provided with sliding support blocks, and the inner wall of the light-shielding angle plate is provided with a sliding support groove, the extension direction of which is along the connecting line of the two light-shielding plates.

[0014] By adopting the above technical solution, by setting sliding support blocks and sliding support grooves, the sliding contact area is reduced and the frictional resistance is lowered. At the same time, the sliding support grooves guide the sliding of the light-shielding angle plate, making the sliding of the light-shielding angle plate stable, and also preventing the light-shielding angle plate from sliding into the inner layer of the glass, thus preventing wear on the inner layer of the glass.

[0015] Optionally, the light-blocking adjustment mechanism includes a support frame, four lifting ropes, and four sets of rope winding assemblies. The support frame includes a support column and a mounting frame. The support column is fixed to the top of the inner glass layer, with the top of the support column located outside the inner glass layer and the bottom of the support column located inside the inner glass layer. The mounting frame is fixed to the bottom of the support column and is used to mount the four sets of rope winding assemblies. Each of the four lifting ropes is connected to a light-blocking angle plate, and the lifting rope is fixed to the top of the light-blocking angle plate. The lifting rope is also fixed to the connection point of two light-blocking plates. Each of the four sets of rope winding assemblies controls the winding and unwinding of the four lifting ropes.

[0016] By adopting the above technical solution, when light transmission is needed, the rope winding assembly releases the lifting rope, allowing the light-blocking angle plate to slide down under its own weight. When light blocking is needed, the rope winding assembly rewinds the lifting rope, thereby lifting the light-blocking angle plate, so that the four light-blocking angle plates cover the top of the inner layer of the glass, which is quite convenient.

[0017] Optionally, the rope winding assembly includes a rope winding gear, a first bevel gear, a second bevel gear, and a rope winding roller. The rope winding gear is rotatably connected to the mounting frame, and its axis is vertical. The first bevel gear is coaxially fixed to the rope winding gear. The rope winding roller is rotatably connected to the mounting frame, and its axis is horizontal. The second bevel gear is coaxially fixed to the rope winding roller and meshes with the first bevel gear. The end of the lifting rope is connected to the rope winding roller. The support column is provided with a guide hole, one end of which is located below the inner glass layer, and the other end is located above the inner glass layer. The light-blocking adjustment mechanism also includes a drive assembly that simultaneously drives the four rope winding gears to rotate.

[0018] By adopting the above technical solution, when winding or unwinding the rope, the drive component drives four rope winding gears to rotate simultaneously. Through the transmission of the first and second bevel gears, the rope winding roller rotates, thereby realizing the winding and unwinding of the lifting rope. This facilitates the sliding of the shading angle plate, thus simplifying the switching between shading and light transmission modes of the roof. The guide hole design facilitates guiding the lifting rope from the inside to the outside of the inner glass layer, making the installation of the lifting rope convenient.

[0019] Optionally, the drive assembly includes a rope winding motor, a main shaft, and a main gear. The main shaft is rotatably connected to the mounting bracket, and the main gear is coaxially fixed to the main gear. The rope winding motor drives the main shaft to rotate. Four rope winding gears are arranged circumferentially on the main gear, and the main gear meshes with the four rope winding gears.

[0020] By adopting the above technical solution, using one rope-winding motor to drive the main gear to rotate can simultaneously drive four rope-winding gears to rotate, reducing the driving source, saving roof costs and reducing roof weight.

[0021] Optionally, the end of the support column located above the inner glass layer is rotatably connected to four guide rollers, and the wheel surface of the guide rollers is provided with guide ring grooves to accommodate the lifting rope.

[0022] By adopting the above technical solution, the lifting rope is turned after being abutted by the roller, which reduces the friction force received by the lifting rope when it moves, making the lifting rope less prone to breakage and improving the service life of the roof.

[0023] Optionally, a leak-proof plate is fixed to the top of the support column. When the four light-shielding angle plates slide close to the support column, the leak-proof plate is located above the top of the four light-shielding angle plates.

[0024] By adopting the above technical solution, the leak-proof plate blocks the tops of the four light-blocking corner plates, thus making it difficult for rainwater to leak from the tops of the four light-blocking corner plates.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Install a light-shielding angle plate. Drive the light-shielding angle plate along the edge of the inner layer of the glass through the light-shielding adjustment mechanism to adjust the light-shielding and light-transmitting state of the roof. This makes it convenient for users to adjust the roof state, while reducing the exposure time of the inner layer of the glass, reducing the adhesion of dust and debris to the inner layer of the glass, and maintaining good light transmittance and aesthetics of the inner layer of the glass.

[0027] 2. The light-shielding angle plate is slidably installed on the outer layer of the support base. When the light-shielding angle plate is slid to the top of the inner layer of the glass, the bottom height of the light-shielding angle plate is lower than the top height of the support base, so that water is less likely to come into contact with the inner layer of the glass and the roof is less likely to leak.

[0028] 3. The system includes a support frame, four lifting ropes, four sets of rope winding assemblies, a rope winding motor, a main shaft, and a main gear. One motor drives four rope winding assemblies to simultaneously wind and unwind four lifting ropes, facilitating the sliding of the outer shading layer and preventing the roof from becoming too heavy.

[0036] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] This application discloses a mobile home roof. (Refer to...) Figure 1 , Figure 2 The roof of the mobile house includes an inner glass layer 1, a supporting base layer 2, a light-shielding outer layer 3, and a light-shielding adjustment mechanism 4 that drives the light-shielding outer layer 3 to slide. The supporting base layer 2 is fixed to the circumferential outer wall of the bottom of the inner glass layer 1, and the light-shielding outer layer 3 is slidably connected to the supporting base layer 2. After the light-shielding outer layer 3 slides, it exposes the outer wall of the inner glass layer 1 or covers the top of the inner glass layer 1.

[0038] Reference Figure 3The inner glass layer 1 is a cone shape composed of four triangular tempered glass plates. The joints of the four triangular tempered glass plates are sealed with hot melt adhesive. An L-shaped plate 5 is fixed at the included angle of the inner wall of the adjacent tempered glass plates. The included angle of the L-shaped plate 5 fits with the included angle of the adjacent tempered glass plates. The L-shaped plate 5 is fixed to the two adjacent tempered glass plates by bolts.

[0039] Reference Figure 3 , Figure 4 The supporting base layer 2 is annular, and its inner wall is fixed to the outer wall of the bottom of the inner glass layer 1 by bolts. The inner and outer annular walls of the supporting base layer 2 are parallel to the inner glass layer 1. The supporting base layer 2 includes four mutually fixed supporting angle plates 21. Each supporting angle plate 21 includes two supporting plates 211 arranged at an angle. The ends of the two supporting plates 211 of the same supporting angle plate 21 are integrally formed, and the included angle between the two supporting plates 211 of the same supporting angle plate 21 is the same as the included angle between the two tempered glass plates on the corresponding inner glass layer 1.

[0040] Reference Figure 1 , Figure 2 The light-shielding outer layer 3 includes four light-shielding angle plates 31, which correspond one-to-one with the four angles of the inner glass layer 1. Each light-shielding angle plate 31 includes two light-shielding plates 311 arranged at an angle. The angle between the two light-shielding plates 311 is the same as the angle of the corresponding inner glass layer 1. The two light-shielding plates 311 of the same light-shielding angle plate 31 are integrally formed.

[0041] Reference Figure 1 , Figure 4 and Figure 5 The light-shielding angle plate 31 is slidably connected to the outer wall of the supporting bottom layer 2. The outer wall of the four edges of the top of the supporting bottom layer 2 is integrally formed with sliding support blocks 6. The inner wall of the light-shielding angle plate 31 is provided with a sliding support groove 7. The extension direction of the sliding support groove 7 is along the connecting line of the two light-shielding plates 311, so that the light-shielding angle plate 31 slides along the edge of the inner glass layer 1 and also slides along the edge of the supporting angle plate 21.

[0042] Reference Figure 5 When the light-shielding angle plate 31 slides to the top of the inner glass layer 1, the supporting bottom layer 2 and the four light-shielding angle plates 31 completely cover the outer wall of the inner glass layer 1. The sliding support block 6 is located at the bottom of the sliding support groove 7. The sliding support block 6 does not detach from the sliding support groove 7. At this time, the bottom height of the light-shielding angle plate 31 is lower than the top height of the supporting bottom layer 2.

[0043] Reference Figure 2 When it rains, the light-blocking angle plate 31 slides to the top of the inner glass layer 1 and seals the top of the inner glass layer 1. At this time, the light-blocking angle plate 31 and the inner glass layer 1 are spaced apart, which has a good sound insulation effect and reduces the noise caused by rain hitting the roof when it rains.

[0044] Reference Figure 2 , Figure 4 The light-blocking adjustment mechanism 4 drives the light-blocking angle plate 31 to slide along the edge of the inner glass layer 1. The light-blocking adjustment mechanism 4 includes a support frame 41, four lifting ropes 42, a drive assembly 43, and four sets of rope winding assemblies 44. The support frame 41 includes a support column 411 and a mounting bracket 412. The support column 411 is fixed to the top of the inner glass layer 1, and the length direction of the support column 411 is vertical. The top of the support column 411 is located outside the inner glass layer 1, and the bottom of the support column 411 is located inside the inner glass layer 1.

[0045] Reference Figure 6 The mounting bracket 412 is fixed to the bottom of the support column 411, and provides mounting space for four sets of rope winding assemblies 44. Each of the four lifting ropes 42 is connected to a corresponding light-shielding angle plate 31. One end of each lifting rope 42 is fixed to the top of the light-shielding angle plate 31, and the other end is fixed to the connection point of two light-shielding plates 311. The other end of each lifting rope 42 is connected to a rope winding assembly 44, and the four sets of rope winding assemblies 44 control the winding and unwinding of the four lifting ropes 42.

[0046] Reference Figure 6 The mounting bracket 412 includes a base plate 4121, a mounting plate 4122 and four vertical shafts 4123. The four vertical shafts 4123 are fixed to the top surface of the base plate 4121, the mounting plate 4122 is fixed to the top of the four vertical shafts 4123, and the support column 411 is fixed to the top surface of the mounting plate 4122.

[0047] Reference Figure 6 The rope winding assembly 44 includes a rope winding gear 441, a first bevel gear 442, a second bevel gear 443, and a rope winding roller 444. The rope winding gear 441 is coaxially rotatably connected to the vertical shaft 4123, and the first bevel gear 442 is coaxially fixed to the rope winding gear 441. The rope winding roller 444 is rotatably connected to the mounting bracket 412, and the second bevel gear 443 coaxially fixes the rope winding roller 444. The axis of the rope winding roller 444 is horizontal. The second bevel gear 443 meshes with the first bevel gear 442, and the end of the lifting rope 42 is connected to the rope winding roller 444.

[0048] Reference Figure 2 , Figure 6 The support column 411 has a guide hole 8 for the lifting rope 42 to pass through. One end of the guide hole 8 is located below the inner glass layer 1, and the other end is located above the inner glass layer 1. The guide hole 8 facilitates the installation of the lifting rope 42.

[0049] Reference Figure 6The drive assembly 43 is used to simultaneously drive four rope winding gears 441 to rotate. The drive assembly 43 includes a rope winding motor 431, a main shaft 432, and a main gear 433. The main shaft 432 is rotatably connected to the bottom of the mounting plate 4122, and the axis of the main shaft 432 is vertical. The main gear 433 is coaxially fixed to the main shaft 432. The rope winding motor 431 is fixed to the top surface of the mounting plate 4122, and the motor shaft of the rope winding motor 431 is coaxially fixed to the main shaft 432. The rope winding motor 431 drives the main shaft 432 to rotate.

[0050] Reference Figure 6 Four rope-winding gears 441 are arranged around the main gear 433 in a circumferential manner. The main gear 433 meshes with the four rope-winding gears 441 simultaneously, and the rotation of the main shaft 432 drives the four rope-winding gears 441 to rotate simultaneously.

[0051] Reference Figure 6 The support column 411 has four mounting slots 9 on its axial sidewall at the end above the inner glass layer 1. Four guide rollers 91 are rotatably connected to the wall of the mounting slots 9. The wheel surface of the guide rollers 91 is provided with guide ring grooves 92 to accommodate the lifting rope 42. The top end of the guide hole 8 extends into the mounting slot 9. After the lifting rope 42 passes through the top end of the guide hole 8, it abuts against the top end of the guide roller 91 and then extends out of the mounting slot 9.

[0052] Reference Figure 6 A leak-proof plate 10 is fixed at the top of the support column 411. When the four light-shielding angle plates 31 slide close to the support column 411, the top of the light-shielding angle plates 31 is attached to the outer wall of the support column 411. At this time, the leak-proof plate 10 is located above the top of the four light-shielding angle plates 31. The leak-proof plate 10 is integrally formed with the top of the support column 411. The leak-proof plate 10 blocks the connection seam between the light-shielding angle plates 31 and the support column 411, so that rainwater is not easy to enter the light-shielding angle plates 31 from the top of the light-shielding angle plates 31 between the inner glass layer 1.

[0053] The implementation principle of a mobile house roof according to an embodiment of this application is as follows: When the indoor lighting needs to be adjusted, the rope motor 431 drives the main shaft 432 to rotate, which in turn drives the four rope gears 441 to rotate. Through the rotation of the first bevel gear 442 and the second bevel gear 443, the rope roller 444 is driven to rotate, thereby realizing the raising and lowering of the lifting rope 42, and allowing the light-shielding angle plate 31 to slide or slide down along the length of the edge of the inner glass layer 1. When the light-shielding angle plate 31 slides up, it covers the top of the inner glass layer 1, and the bottom of the inner glass layer 1 is covered by the supporting bottom layer 2, thus making the roof light-shielding. When the light-shielding angle plate 31 slides down, the top of the inner glass layer 1 is exposed, making the roof light-transmitting.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
