Description

Technical Field

[0001] This invention relates to the technical field of sightseeing elevators, and in particular to a small-shaft, fully circular sightseeing elevator car assembly. Background Technology

[0002] The small shaft full-circular sightseeing elevator car assembly is an elevator system designed specifically for space-constrained scenarios such as villas and scenic spots. Its core features include: adopting a 360° continuous circular curved glass car wall to maximize the sightseeing view; adapting to narrow shaft spaces (usually with a diameter ≤ 2.5 meters) and achieving a compact layout through structural optimization; and integrating aesthetic design and functionality to meet the needs of high-end buildings.

[0003] Traditional circular sightseeing elevators generally adopt an exposed straight beam structure, consisting of a car top, car bottom, and external straight beams on both sides forming a frame. The glass walls of the car are fixed to the outside of the frame with bolts. The straight beams are usually I-beams or rectangular tubes, occupying about 15%-20% of the effective space in the shaft. The car bottom retains the traditional lower beam structure, requiring additional pit support.

[0004] In existing circular sightseeing elevators, exposed straight beams encroach on the shaft cross-section, resulting in a reduction of effective passenger space by more than 30% in small shafts; moreover, the outward protrusion of the straight beams disrupts the visual continuity of the circular car, creating blind spots. Summary of the Invention

[0006] This application provides a small-shaft, fully circular sightseeing elevator car assembly, which adopts the following technical solution: A small-shaft, fully circular sightseeing elevator car assembly includes a car top, a car, and a car bottom. The car includes a continuous circular curved car wall made of glass, with symmetrical vertical notches on the car wall. Two straight beams are respectively embedded in the vertical notches and form a gantry structure with the car top and car bottom. The top of the straight beams is rigidly connected to the car top, and the bottom is welded and fixed to the reinforcing structure of the car bottom. The traditional lower beam structure of the car bottom is eliminated.

[0010] Preferably, the bottom of the car floor is provided with a three-dimensional load-bearing network formed by transverse reinforcing tubes and longitudinal reinforcing tubes, and the longitudinal reinforcing tubes extend through the bottom of the straight beam to the annular bottom plate.

[0011] Preferably, the upper surface of the car floor is covered with anti-slip ceramic material, and the car floor as a whole forms a 5° inclined slope towards the drain.

[0012] Preferably, an arc-shaped decorative panel is provided on the outer side of the vertical notch, the decorative panel is smoothly connected to the curved surface of the compartment wall, a U-shaped sealing groove is provided between the decorative panel and the compartment wall, and the sealing groove is filled with an elastic buffer seal.

[0013] Preferably, the straight beams are symmetrically distributed with the car's central axis as a reference, and triangular reinforcing plates are welded between the straight beams and the car wall. Guide shoes and safety clamp assemblies are built into the slots of the straight beams.

[0014] Preferably, a cleaning assembly for automatically cleaning the outer wall of the car is provided on one side of the car roof and outside the car. The cleaning assembly includes an annular fixed rail fixed to the bottom of the roof and coaxially arranged therewith. A slider is slidably connected inside the annular fixed rail via a drive module. The slider moves circumferentially along the annular groove inside the annular fixed rail via the drive module. A mounting base is fixedly installed at the bottom of the slider. A long rod is provided on one side of the bottom of the mounting base. A positioning plate is fixedly installed at the bottom of the long rod. A placement area is formed between the mounting base, the positioning plate, and the long rod. The opening of the placement area faces the outer wall of the car. A drive motor is provided inside the mounting base. The output end of the drive motor is connected to a rotating rod via a coupling. An installation sleeve is coaxially sleeved on the rotating rod. A positioning brush is provided on one side of the installation sleeve. A silicone scraper is provided on one side of the installation sleeve.

The L-shaped groove in the integrated block forms an interlocking structure with the cleaning component. Several stamping nozzles are provided inside the integrated block. The stamping nozzles are 45° downwards towards the positioning brush and the silicone scraper on the rotating rod.

[0016] In summary, this application has the following beneficial effects: 1. To address the issue of exposed straight beams occupying hoistway space, this invention symmetrically embeds two straight beams into vertical notches in the car wall, forming a closed gantry frame together with the car top and bottom. Further optimized, the top of the straight beams is rigidly connected to a cross-shaped upper beam, and the bottom is welded to the car bottom reinforcing ribs, eliminating the traditional lower beam. This design increases hoistway utilization by 40% while maintaining the visual integrity of the car wall.

[0017] 2. To address the deep pit requirements resulting from traditional lower beam structures, this invention innovatively employs a combination of a ring-shaped base plate and U-shaped reinforcing ribs. Further optimized, the first reinforcing ribs are symmetrically distributed along the central axis, and the second reinforcing ribs are diagonally welded to form a stress-dispersing structure, which, together with transverse and longitudinal reinforcing tubes, constitutes a three-dimensional load-bearing network. This structure reduces the pit depth to below 1.2 meters and increases torsional strength by 35%.

[0018] 3. To solve the cleaning challenge of circular glass car cabins, this invention integrates a ring-shaped track-type cleaning component on the car roof. Further optimized, a slider-driven rotating brush and silicone scraper, in conjunction with a high-pressure spray module, achieve a fully automatic "wetting-brushing-scraping" cleaning process with high efficiency. The L-shaped self-cleaning component uses a 45° pressurized nozzle for closed-loop maintenance of the tools, extending their service life by 200%.

[0019] 4. To eliminate the visual discontinuity caused by the embedded straight beam, this invention provides a curved decorative panel with equal curvature on the outside of the vertical notch. Further optimized, the U-shaped sealing groove is filled with an elastic buffer, achieving IP54 waterproofing while simultaneously transferring glass stress to the straight beam via a concealed silicone connector, resulting in a seamless, continuous curved surface effect.

[0020] 5. By embedding the straight beam into the pre-set notch in the car wall, the traditional exposed straight beam avoids occupying the hoistway space, optimizes the car space, and improves the hoistway utilization rate. At the same time, the traditional lower beam structure of the car bottom is eliminated, and the straight beam is directly fixed in the car bottom reinforcement structure, which can further reduce the required pit depth and adapt to the limited installation conditions of small hoistways.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0023] This invention discloses a small-shaft, fully circular sightseeing elevator car 3 assembly. By embedding the straight beam 33 into a pre-set notch in the car wall 31, the traditional exposed straight beam 33 avoids occupying shaft space, optimizing the car 3 space and improving shaft utilization. Simultaneously, the traditional lower beam structure of the car bottom 2 is eliminated, and the straight beam 33 is directly fixed to the reinforcing structure of the car bottom 2, further reducing the required pit depth and adapting to the limited installation conditions of small shafts. Figure 1 As shown, from top to bottom, it includes the car top 1, the car body 3, and the car bottom 2.

[0024] The car roof 1 consists of a roof plate 11, an upper beam 12, and a suspended ceiling from top to bottom. The top surface of the roof plate 11 is welded with three U-shaped top stiffeners 13 to enhance the deformation resistance of the roof plate 11. The upper beam 12 has a cross-shaped cross section, which has high structural strength and stability. The suspended ceiling is installed at the bottom of the car roof 1 and integrates lighting fixtures and ventilation openings.

[0025] The car roof 1 adopts a layered design, achieving functional optimization through the synergistic effect of materials and structure. The roof slab 11 serves as the load-bearing surface, with three welded U-shaped stiffeners 13 forming a reinforcing rib structure. The bending resistance of the U-shaped cross-section disperses the top load, significantly improving deformation resistance. Simultaneously, the welding process of the stiffeners reduces residual stress from welding deformation, avoiding localized stress concentration. The cross-shaped cross-section design of the upper beam 12 enhances structural stability through multi-directional support: longitudinal beams resist vertical bending moments, while transverse beams suppress lateral torsion, creating a spatial truss effect that maintains the rigidity of the car roof 1 under dynamic loads (such as elevator start-stop vibrations). The suspended ceiling, as a functional layer, reduces overall weight through modular installation. Its integrated lighting fixtures and ventilation openings adopt an embedded layout, avoiding protruding components that interfere with airflow or lighting uniformity, balancing aesthetics and practicality.

[0026] Furthermore, a cover 14 is provided on one side of the car roof 1. The curvature of the cover 14 is consistent with that of the car roof 1. The cover 14 covers the upper beam 12 to prevent dust from entering and to enhance the overall aesthetics.

[0027] The car bottom 2 includes an annular bottom plate 21, a first reinforcing rib 22 and a second reinforcing rib 23. Both the first reinforcing rib 22 and the second reinforcing rib 23 are U-shaped plates and are connected by staggered diagonal welding to prevent stress concentration. The first reinforcing rib 22 is distributed along the central axis of the annular bottom plate 21, and the second reinforcing rib 23 is symmetrically distributed on the outside of the first reinforcing rib.

[0028] The car bottom 2 adopts a combined structure of annular bottom plate 21 and U-shaped reinforcing ribs. Its core principle lies in optimizing load distribution and improving overall rigidity. The annular bottom plate 21, as the foundation bearing surface, can evenly distribute the pressure of the car 3 and the load, reducing the risk of local deformation. The first reinforcing rib 22 is distributed along the central axis, directly bearing the main longitudinal load, and enhances structural stability through the high bending resistance of the U-shaped cross-section. The second reinforcing rib 23 is symmetrically distributed on the outer side, forming an auxiliary support frame, improving torsional resistance, and preventing the bottom plate from warping or twisting under dynamic loads (such as elevator start-stop and vibration). The application of staggered diagonal welding further optimizes stress distribution, avoiding local stress peaks caused by weld concentration, and reducing the risk of fatigue failure. This design combines materials mechanics and welding technology to ensure that the car bottom 2 maintains high reliability and durability during long-term use.

[0029] Furthermore, the upper surface of the car bottom 2 is covered with a floor 24, which is made of anti-slip ceramic tiles or rock slabs, has a good anti-slip effect, and is flat and seamless overall.

[0030] Furthermore, the bottom of the car bottom 2 is equipped with a transverse reinforcing tube 25 and a longitudinal reinforcing tube 26, and the longitudinal reinforcing tube 26 penetrates the bottom of the straight beam 33 to form a three-dimensional load-bearing network.

[0031] Furthermore, the car bottom 2 is slightly tilted 5° towards the drain to prevent water accumulation in the car bottom 2.

[0032] The car 3 includes a car wall 31, a double-leaf centrally-parting door 32, and straight beams 33. Both the car wall 31 and the double-leaf centrally-parting door 32 are made of glass. The car wall 31 has symmetrically distributed vertical notches, and the two straight beams 33 are respectively embedded in these vertical notches, forming a gantry structure with the upper beam 12 and the car floor 2. The car 3 adopts a composite structure of glass car wall 31 + double-leaf centrally-parting door 32 + straight beam 33 gantry structure. Its core principle lies in the synergistic optimization of material properties and mechanical structure. The glass car wall 31 not only meets the aesthetic requirements of modern elevators, but its high light transmittance also improves the interior lighting of the car 3. The symmetrically distributed vertical notches allow the straight beams 33 to be precisely embedded and form a closed gantry structure with the upper beam 12 and the car floor 2, significantly improving overall rigidity. The opening and closing mechanism of the double-leaf centrally-parting door 32 saves space, making it particularly suitable for narrow shaft environments. At the same time, the seamless connection between the glass material and the car wall 31 reduces wind resistance and noise. The embedded layout of the straight beam 33 optimizes the force transmission path, evenly distributing the load of the car 3 to the four support points of the gantry frame, thus avoiding stress concentration at the glass joints. Furthermore, the geometric stability of the gantry frame effectively resists lateral vibrations during elevator operation, ensuring stability under high-speed conditions.

[0033] Furthermore, the side wall 31 is a continuous circular curved surface, with an arc-shaped decorative panel sealing the outer side of the vertical notch, and the curvature of the decorative panel is completely consistent with that of the side wall 31. A U-shaped groove is provided at the junction of the decorative panel and the curved glass, with sponge or rubber pads placed inside the U-shaped groove to cushion vibrations and ensure a waterproof seal, visually achieving an integrated effect between the straight beam 33 and the side wall 31. Connectors are provided on the inner side of the curved glass to connect with the decorative panel of the straight beam 33. The connectors are hidden at the edge of the glass, not obstructing the view, and the gaps are filled with silicone sealant to prevent water seepage.

[0034] The car wall 31 adopts a composite design of continuous circular curved surface + arc-shaped decorative panel + concealed connection. Its core principle lies in the optimization of fluid mechanics and the integration of vision and function. The continuous circular curved surface not only conforms to the streamlined aesthetics of modern elevators, but also effectively reduces the air vortex resistance of the car 3 during high-speed operation (reducing wind resistance by about 15% compared to the flat design). At the same time, the stress distribution characteristics of the curved glass can improve wind pressure resistance. The arc-shaped decorative panel on the outside of the vertical notch adopts the equal curvature sealing technology. The CNC bending process ensures that the curvature error with the car wall 31 is not missed, achieving a seamless visual transition. The sponge / gasket embedded in the U-shaped groove inside forms a double buffer sealing system: the elastic material absorbs the micro-vibration during elevator start and stop, and fills the assembly tolerance through compression deformation, forming an IP54 waterproof barrier. The concealed connectors transform the mechanical connection between the straight beam 33 and the glass into a chemical bond through concealed silicone injection process. While ensuring structural strength, it completely eliminates the interference of exposed bolts on the viewing view, and the weather resistance of silicone ensures long-term sealing reliability.

[0035] Furthermore, the double straight beams 33 are symmetrically distributed along the central axis of the car 3, located at 180° positions on both sides of the door opening side, with vertical notches facing away from each other. Components such as guide shoes and safety gears are directly installed within the slots of the straight beams 33, without being exposed or occupying space. This double straight beam 33 system adopts a mechanical layout of central axis symmetry and back-to-back embedded design, its core principle based on space optimization and load balance theory. The double straight beams 33 are symmetrically distributed at 180° with the central axis of the car 3 as a reference, forming a stable couple structure, allowing the lateral forces during elevator operation to be evenly distributed. The innovative design of the back-to-back vertical notches, combined with the slot-embedded installation of key components such as guide shoes and safety gears, further enhances this effect.

[0036] Furthermore, the top of the straight beam 33 is rigidly connected to the upper beam 12 of the car roof 1 by bolts, and the bottom end is directly welded to the reinforcing rib of the annular bottom plate 21, eliminating the traditional lower beam and reducing the pit height requirement; and a triangular reinforcing plate is welded between the straight beam 33 and the car wall.

[0037] The door operator system is integrated into the upper beam 12 of the car top 1. It drives the door body to move along the arc-shaped guide rail through the screw slide block drive and the swing arm transmission.

[0038] Furthermore, a touch-sensitive control panel is embedded in one of the straight beams 33 for controlling the elevator. Example

[0039] like Figure 3 , Figure 4 and Figure 5As shown, a cleaning assembly 4 for automatically cleaning the outer wall of the car 3 is provided on one side of the car top 1 and outside the car 3. The cleaning assembly 4 includes an annular fixed rail 41 fixed to the bottom of the top plate 11 and coaxially arranged therewith. A slider 42 is slidably connected inside the annular fixed rail 41 through a drive module. The slider 42 moves circumferentially along the annular groove inside the annular fixed rail 41 through the drive module. A mounting base 43 is fixedly installed at the bottom of the slider 42. A long rod 44 is provided on one side of the bottom of the mounting base 43. A positioning plate 45 is fixedly installed at the bottom of the long rod 44. A placement area is formed between the mounting base 43, the positioning plate 45 and the long rod 44. The opening of the placement area faces the outer wall of the car 3. A drive motor is provided inside the mounting base 43. The output end of the drive motor is connected to a rotating rod 46 through a coupling. A mounting sleeve 47 is coaxially sleeved on the rotating rod 46. A positioning brush 48 is provided on one side of the mounting sleeve 47, and a silicone scraper 49 is provided on one side of the mounting sleeve 47. A spray module 410 for spraying cleaning fluid is provided on the long side of the long rod 44. The nozzles in the spray module 410 are vertically oriented towards the outer wall of the car 3. First, the mounting base 43 is driven by the slider 42, and the cleaning fluid sprayed by the nozzles of the spray module 410 is sprayed all over the outer wall of the car 3 to soften the dust and impurities on the outer wall of the car 3. Then, the rotating rod 46 is driven by the drive motor, so that the positioning brush 48 is attached to the outer wall of the car 3 and the softened impurities on the surface of the outer wall of the car 3 are brushed away with the help of the slider 42. Then, the rotating rod 46 is driven by the drive motor, so that the silicone scraper 49 is attached to the outer wall of the car 3 and the impurities on the surface of the outer wall of the car 3 are scraped away with the help of the slider 42, thus realizing the automated cleaning function.

[0040] Specifically, the cleaning component 4 adopts an intelligent cleaning architecture of a ring track and multi-module collaboration. Its core technology principle is reflected in the precise coordination between three-dimensional spatial motion and cleaning process. The ring fixed track 41 is set coaxially with the car top 1 to form a closed-loop motion path. The slider 42 is controlled by a servo drive module to achieve a positioning accuracy of ±0.05mm, ensuring that the cleaning component can cover 100% of the surface area of ​​the outer wall of the car 3.

[0041] Cleanup Component 4 integrates three major functional modules: 1) The spray module 410 uses a high-pressure atomizing nozzle to spray environmentally friendly cleaning liquid at a 30° fan angle. Its nano-sized droplets can penetrate into the surface micropores.

[0042] 2) The rotating cleaning unit drives the carbon fiber positioning brush 48 and the silicone scraper 49 through a variable frequency motor. The hardness of the brush bristles and the elastic modulus of the scraper are optimized and matched so that it can remove stubborn stains without damaging the glass coating.

[0043] 3) The closed-loop control system monitors the position of slider 42 in real time through a Hall sensor and adjusts the cleaning fluid spray volume in conjunction with a flow meter. The entire cleaning process strictly follows the industrial cleaning standard of "wetting-brushing-scraping," which is 8 times more efficient than manual cleaning.

[0044] like Figure 6 As shown, a self-cleaning component 5 is further fixedly installed at the bottom of the annular fixed rail 41. The self-cleaning component 5 is used to clean the positioning brush 48 and the silicone scraper 49. Specifically, the self-cleaning component 5 includes a positioning block 51. An integrated block 52 with an L-shaped cross-section is fixedly installed on one side of the positioning block 51. The L-shaped groove inside the integrated block 52 forms an interlocking structure with the cleaning component 4. Several stamping nozzles 53 are arranged inside the integrated block 52. The stamping nozzles 53 face downward at 45° toward the positioning brush 48 and the silicone scraper 49 on the rotating rod 46. The self-cleaning component 5 adopts a collaborative design of L-shaped interlocking + directional stamping. Its core principle is to achieve closed-loop maintenance of the cleaning tool. The positioning block 51 at the bottom of the annular fixed rail 41 and the integrated block 52 form a rigid connection. The precision engaging structure of the L-shaped groove ensures that the cleaning component does not shift when moving, while forming a closed cleaning chamber. The stamping nozzles 53 are arranged in a 45° angled array, generating a 0.2MPa fan-shaped water curtain through the Bernoulli effect, covering the fiber gaps of the positioning brush 48 and the grooves of the silicone scraper 49. After the cleaning assembly completes its work on the outer wall of the car 3, the slider 42 drives the rotating rod 46 into the groove of the integrated block 52. At this time, the nozzles activate the high-pressure pulse mode, and the water flow penetrates the roots of the brush bristles in an alternating vortex pattern, effectively removing embedded particulate contaminants; the silicone scraper 49 then peels off surface adhering substances through the action of a water wedge. This innovative design integrates the maintenance process of the cleaning tools into the main motion trajectory, eliminating the need for additional downtime.

[0045] Working principle: First, when the elevator starts, the straight beam 33 embedded in the vertical notch of the car wall 31, together with the car top 1 and car bottom 2, forms a gantry load-bearing system. The top of the straight beam 33 is fixed to the cross-shaped upper beam 12 by high-strength bolts, and the bottom is directly welded to the reinforcing rib node of the annular bottom plate 21 of the car bottom 2. This design transforms the traditionally dispersed frame stress into a centralized load transmission path, allowing the dynamic load of the car 3 to be distributed in three levels through the straight beam 33-reinforcing rib-three-dimensional load-bearing network, and finally evenly transmitted to the hoistway guide rails. After eliminating the lower beam, the thickness of the car bottom 2 is reduced to 150mm, and the required pit depth is reduced by 30%.

[0046] Then, when the elevator is subjected to lateral vibration during operation, the continuous circular curved surface of the car wall 31 resists wind pressure through the prestress of the glass tempered layer. At the same time, the triangular reinforcing plates welded between the straight beam 33 and the glass wall form local rigid nodes to suppress micro-deformation of the glass. The symmetrically distributed U-shaped reinforcing ribs, through the diagonal welding process, enable the car bottom 2 to redistribute stress through the staggered stiffener network when subjected to uneven loads (such as passengers standing in a concentrated manner), thus preventing local stress from exceeding the allowable strength of the glass.

[0047] Subsequently, the automatic cleaning system starts according to the preset program. The servo drive module in the annular fixed rail 41 drives the slider 42 to move circumferentially at a speed of 0.2 m / s. The fan-shaped nozzles of the spray module 410 spray environmentally friendly cleaning fluid at a pressure of 0.5 MPa, covering the outer wall of the car 3; at the same time, the drive motor drives the carbon fiber positioning brush 48 to rotate at a speed of 1200 r / min, and the brush bristles form a 3 mm compression with the glass surface, peeling off the attached dirt. The silicone scraper 49 then scrapes off the residual liquid film with a contact pressure of 5 N / cm². The entire process is controlled by PLC to ensure no water stains remain.

[0048] Furthermore, when the cleaning components return to their initial position, the punch nozzle 53 of the L-shaped integrated block 52 activates, spraying high-pressure water at a 45° angle. The water flow generates a vortex effect between the fibers of the positioning brush 48, removing particulate contaminants; the silicone scraper 49 then peels off surface deposits through a water wedge action. Cleaning wastewater flows into the floor drain along a 25° slope at the bottom of the car, preventing water accumulation and structural corrosion.

[0049] Finally, the elevator door operator system drives the door body through the screw slide assembly built into the upper beam 12. The swing arm mechanism converts linear motion into an arc trajectory, allowing the double-leaf center-parting door 32 to open and close smoothly along the customized guide rail. The touch control panel is integrated inside the decorative panel of the straight beam 33, enabling blind operation through capacitive sensing technology and perfectly hidden within the curved glass surface. Through structural innovation and the synergistic effect of functional modules, the entire system ultimately achieves a triple breakthrough in space utilization, aesthetic performance, and ease of maintenance in small shaft conditions.

[0050] 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.
