[0021] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 This patent provides a technical solution: a spherical car glass door, including a stainless steel frame 2, a door panel connector 1 fixedly connected to the top side of the stainless steel frame 2 by bolts, a spherical curved tempered glass 3 fixedly installed on the inner side of the stainless steel frame 2, a left outer cover 5 and a right outer cover 6 fixedly installed on the left and right sides of the stainless steel frame 2 respectively, and a left pressure plate 7 and a right pressure plate 8 fixedly installed on the left and right ends of the front side of the spherical curved tempered glass 3.

[0023] Connection between stainless steel frame 2 and door panel connector 1: Use M8 high-strength bolts, 4 in total, evenly distributed at the connection between door panel connector 1 and stainless steel frame 2, with a tightening torque of 30 N·m to ensure a stable connection.

[0024] Glass fixing: High-strength structural adhesive is used to bond the spherical curved tempered glass 3 to the stainless steel frame 2, left pressure plate 7, and right pressure plate 8, with the adhesive layer thickness controlled at 2mm; at the same time, a metal clip is set every 200mm along the edge of the glass to help fix the glass and enhance the reliability of the connection.

[0025] The bottom of the stainless steel frame 2 is fitted with a load-bearing roller 12 and a guide bearing roller 13 through pre-drilled threaded holes.

[0026] Stainless steel frame 2: 2000mm long, 1000mm wide, with a frame cross-section of 50mm×50mm×3mm.

[0027] Spherical curved tempered laminated glass 3: spherical radius 1500mm, glass thickness 10mm (including 1.5mm thick interlayer film), size compatible with stainless steel frame, with 10mm installation gap reserved around all four sides.

[0028] Left outer cover 5 and right outer cover 6: 1800mm long, 150mm wide, and 2mm thick, they are installed to fit snugly against the stainless steel frame and cover the sides of the frame.

[0029] Load-bearing roller 12 and guide bearing roller 13: roller diameter 100mm, width 50mm, to ensure compatibility with elevator rails and ensure smooth car door operation.

[0030] The bearing model 16 is 6205, with a rated dynamic load of 14.0kN, a rated static load of 10.8kN, and a maximum speed of 1000r / min, which meets the load and operation requirements of the car door.

[0031] Guide bearing roller 13: adopts deep groove ball bearing, model 6004, rated dynamic load 7.85kN, rated static load 5.30kN, to ensure accurate guidance during car door operation.

[0032] The front lower sealing plate 9 and the rear lower sealing plate 10 are fixedly installed on the front, back and rear bottom of the stainless steel frame 2, respectively. The front upper sealing plate 4 and the rear upper sealing plate 11 are fixedly installed on the front and rear top of the stainless steel frame 2, respectively.

[0033] Stainless steel frame 2: Made of 304 stainless steel, with a tensile strength ≥520MPa and a yield strength ≥205MPa, it has good corrosion resistance and strength.

[0034] Spherical curved tempered laminated glass 3: The tempering degree meets national standards, and the surface stress is ≥90MPa; the interlayer uses PVB film with a thickness of 1.5mm, which has good impact resistance and bonding strength.

[0035] Left outer cover 5, right outer cover 6, left pressure plate 7, and right pressure plate 8: all are made of aluminum alloy, grade 6061, with a tensile strength ≥260MPa. They are lightweight and high-strength, making them easy to install and maintain.

[0036] Specifically, the door panel connector 1 is Z-shaped, and the corner joints of the door panel connector 1 are integrally formed with reinforcing ribs 14.

[0037] The reinforcing rib 14 is provided to increase the compressive strength of the door panel connector 1.

[0038] Specifically, the heavy-duty bearing roller 12 includes a wheel body 15, a bearing 16, and a connecting ring 20. The wheel body 15 has a mounting hole in the middle. The outer side wall of the outer ring of the bearing 16 is fixedly installed on the inner side wall of the mounting hole. A threaded rod 17 is fixedly installed on the inner side wall of the inner ring of the bearing 16. A pressure ring 18 is integrally formed on the side wall of the threaded rod 17. The top of the outer side wall of the connecting ring 20 is fixedly installed on the bottom of the stainless steel frame 2. The end of the threaded rod 17 passes through the connecting ring 20 and is screwed with a nut 22. The left side surface of the connecting ring 20 has positioning grooves 21 at both the upper and lower ends. The right side surface of the pressure ring 18 has positioning rods 19 integrally formed at both the upper and lower ends. The positioning rods 19 are inserted into the positioning grooves 21.

[0039] Traditionally, the load-bearing rollers at the bottom of the car door are connected to the nuts by bolts passing through the connecting rings on the bottom side of the door panel. Because these rollers are load-bearing rollers, the bearings inside have high compressive strength, resulting in extremely high friction between the inner and outer rings of the bearing. When the outer ring of the bearing is severely compressed and jammed, it can easily cause the inner ring to rotate simultaneously, causing the threaded rod and nut connected to it to rotate and loosen, leading to the nut falling off.

[0040] By setting the positioning rod 19 to be inserted into the positioning groove 21, the threaded rod 17, the nut 22 and the inner ring of the bearing 16 can be fixed and prevented from rotating, thus preventing the nut 22 from falling off.

[0041] Specifically, the diameter of the pressure ring 18 is the same as the diameter of the connecting ring 20.

[0042] By making the diameter of the pressure ring 18 the same as the diameter of the connecting ring 20, the pressing area of ​​the pressure ring 18 on the connecting ring 20 can be increased, thereby increasing the pressing force.

[0043] Specifically, the right end of the positioning rod 19 is provided with a tapered surface 23.

[0044] The tapered surface 23 reduces the size of the right end of the positioning rod 19, making it easier for the positioning rod 19 to be inserted into the positioning groove 21.

[0045] Specifically, a rubber gasket 24 is fitted on the left side of the nut 22.

[0046] The rubber gasket 24 is provided to prevent the nut 22 from wearing on the connecting ring 20.

[0047] Working principle: This car door panel is used in the structure of a spherical sightseeing elevator. It adopts high-strength tempered laminated glass 3, and the outer surface curvature radius of the single curved glass is matched with the spherical outline of the car (radius R1107) using the single-piece curved glass integral molding technology. The overall frame of the door panel is composed of 304 stainless steel. The guide shoes of the door panel are composed of a combination of load-bearing rollers and heavy-duty rollers, which greatly reduces the coefficient of friction and improves the smoothness of the door panel.
