Description

Technical Field

[0001] The present application relates to the technical field of elevators, and in particular to a car and an elevator. Background Art

[0002] With the rapid development of technology and the increasing height of buildings, elevators are used more and more frequently in daily life. The elevator car is one of the core components of the elevator, mainly used to carry and transport people and materials.

[0003] A typical elevator car consists of a roof, a floor, a door connected between the roof and the floor, and three side panels. Each of the three side panels is composed of multiple vertical panels. The decorative surface of the vertical panels is rectangular, and the long sides of the vertical panels are perpendicular to the roof and floor, and the short sides are parallel to the roof and floor. After splicing, the joints between adjacent vertical panels are also set along the longitudinal direction. However, this splicing method requires installers to enter the shaft to complete the assembly, which is cumbersome and poses a risk of falling to installers.

[0036] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0037] In the description of this application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0038] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0039] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0040] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is described as being "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is described as being "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0041] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

[0042] As mentioned above, in a traditional elevator car, the three side wall panels are composed of multiple vertical wall panels spliced ​​together. The decorative surface of the vertical wall panels is rectangular, and the long sides of the vertical wall panels are perpendicular to the car roof and car bottom, and the short sides are parallel to the car roof and platform. After splicing, a longitudinal seam will be formed between adjacent vertical wall panels. However, the height of the vertical wall panels, that is, the length of the long side, is usually equal to the height of the car. The height of the elevator cars currently on the market is greater than its width and depth. Therefore, the size of a single vertical wall panel is large, and the strength will be relatively reduced. To improve the strength of the vertical wall panels, it can only be done by increasing the thickness of the panels or adding reinforcement components, which will significantly increase the cost. At the same time, due to the high height of the vertical wall panels, when splicing and assembling them, the installers need to enter the shaft to complete the installation. The installation process is cumbersome and there is a risk of falling for the installers. In addition, due to the existence of the longitudinal seam, when adding additional functional components such as handrails that meet national standards, the legs or fixing holes of the functional components need to avoid the seam of the wall panels 20, which reduces compatibility.

[0043] Based on this, an embodiment of the present application provides a car with high strength, good compatibility and easy assembly. Figure 1 as well as Figure 2The car of one embodiment includes a car bottom 11 and a car top 12 arranged opposite to each other, and a front wall 13, a rear wall 14 and two side walls 15 connected between the car bottom 11 and the car top 12. The front wall 13 is provided with a doorway 134. The rear wall 14 is arranged opposite to the front wall 13. The two side walls 15 are connected between the front wall 13 and the rear wall 14. The rear wall 14 and the two side walls 15 each include at least two wall panels 20 connected in sequence from the car bottom 11 to the car top 12. Figure 3 Each wall panel 20 includes a panel 21 and a bent edge 22. The panel 21 has a decorative surface 211 facing the interior of the car. The bent edge 22 is arranged around the edge of the panel 21 and extends away from the decorative surface 211. Two adjacent wall panels 20 are connected by the bent edge 22. Here, "two adjacent wall panels 20 are connected by the bent edge 22" means that the bent edge 22 of at least one of the two adjacent wall panels 20 is connected to the other wall panel 20, for example, by a threaded connection such as a bolt, or fixedly connected by welding or bonding.

[0044] In the aforementioned car, the rear wall 14 and two side walls 15 comprise at least two wall panels 20 connected sequentially from the car floor 11 to the car ceiling 12, effectively reducing the height of each wall panel 20. During assembly, workers can stand inside the car and install the wall panels 20 layer by layer from bottom to top to complete the assembly of the side walls 15 and rear wall 14. This eliminates the need to enter the hoistway, thus avoiding the risk of falling and improving safety. The size of each wall panel 20 is significantly reduced compared to traditional wall panels, increasing the strength of each wall panel 20. Furthermore, the edges of the panels 21 of each wall panel 20 are each provided with a bent edge 22, thereby reinforcing each wall panel 20 and improving the overall strength of the car while maintaining cost. Adjacent wall panels 20 are connected by a bent edge 22, which extends away from the decorative surface 211, thereby ensuring the connection and fixation of each wall panel 20 without affecting the appearance of the decorative surface 211. The front wall 13, rear wall 14, and two side walls 15 are interconnected to form a single unit, providing sufficient structural strength for use. No additional reinforcement structures, such as columns, are required, simplifying the structural design, saving material costs, and shortening installation time. After assembly, the seam between two adjacent wall panels 20 on the same side is horizontal. Optional components such as handrails can be installed on the same wall panel 20, preventing interference between the fixed legs of these components and the seam between the wall panels 20, thereby improving the compatibility of the car.

[0045] See also Figure 3 as well as Figure 4In one embodiment, the bent edge 22 includes two long sides 221 and two short sides 222. The two long sides 221 are oppositely arranged and parallel to the car floor 11, while the two short sides 222 are oppositely arranged between the two long sides 221 and perpendicular to the car floor 11. In other words, the wall panel 20 has a rectangular structure. Furthermore, along the direction from the car floor 11 to the car roof 12, adjacent wall panels 20 are connected by the long sides 221, for example, by threaded fasteners, welding, or bonding. In the side wall 15, one short side 222 of the wall panel 20 is connected to the front wall 13, and the other short side 222 is connected to the decorative surface 211 of the rear wall 14. Similarly, these connections can also be made by threaded fasteners, welding, or bonding.

[0046] See also Figure 5 In one embodiment, a first connection hole 2211 is defined along the long side 221, and the first connection holes 2211 of two adjacent wall panels 20 communicate with each other along the direction from the car bottom 11 to the car roof 12. Specifically, the first connection holes 2211 can be threaded with a connecting member such as a bolt. By connecting the long sides 221 of two adjacent wall panels 20 on the same side via the connecting member, the two adjacent wall panels 20 can be secured together. Similarly, the long side 221 of the wall panel 20 closest to the car roof 12 can also be secured to the car roof 12 via a connecting member threaded through its first connection hole 2211. Furthermore, a plurality of first connection holes 2211 are provided, and the plurality of first connection holes 2211 are spaced apart along the length of the long side 221, thereby enhancing the securing effect between the two adjacent wall panels 20.

[0047] Further, see Figure 4 In the side wall 15, the short side 222 of the wall plate 20 is provided with a second connection hole 2221. Figure 8 as well as Figure 9 In the rear wall 14, the decorative surface 211 of the wall panel 20 is provided with a third connection hole 2111, which communicates with the second connection hole 2221. Thus, by inserting a connecting member such as a bolt through the communicating second connection hole 2221 and third connection hole 2111, the rear wall 14 is securely connected to one short side 222 of the wall panel 20 of the side wall 15. Similarly, the other short side 222 of the wall panel 20 of the side wall 15 can also be connected to the front wall 13 via a connecting member inserted through the second connection hole 2221.

[0048] See also Figure 5In one embodiment, a first flange 231 is provided at the end of the long side 221 facing away from the panel 21. The first flange 231 extends toward the other long side 221. The first flange 231 reinforces the long side 221, thereby increasing the strength of the wall panel 20. Similarly, a second flange 232 is provided at the end of the short side 222 facing away from the panel 21. The second flange 232 extends toward the other short side 222. The first flange 231 reinforces the short side 222, thereby further increasing the strength of the wall panel 20.

[0049] See also Figure 6 as well as Figure 7 Optionally, in one embodiment, the length of the short side 222 is less than the width of the panel 21, the length of the long side 221 is equal to the length of the panel 21, the height of the long side 221 protruding from the panel 21 is greater than the height of the short side 222 protruding from the panel 21, and the projection of the first flange 231 on the panel 21 covers the ends of the short side 222. In this way, the two long sides 221 can respectively wrap around the ends of the two short sides 222, so that the two long sides 221 and the two short sides 222 together form a closed ring structure, thereby reducing the risk of light leakage from the cabin.

[0050] Understandably, in another embodiment, the length of the long side 221 may be shorter than the length of the panel 21, the length of the short side 222 may be equal to the width of the panel 21, the height of the short side 222 protruding from the panel 21 may be greater than the height of the long side 221 protruding from the panel 21, and the projection of the second flange 232 on the panel 21 may cover the end of the long side 221. In this way, the two short sides 222 can respectively wrap around the two ends of the two long sides 221, and the two long sides 221 and the two short sides 222 can together form a closed ring structure, thereby reducing the risk of light leakage from the cabin.

[0051] See also Figure 1 as well as Figure 2 The front wall 21 includes a first front panel 131 and a second front panel 132 spaced apart from each other, and a crossbeam 133 connecting the first and second front panels 131, 132. The first and second front panels 131, 132, and the crossbeam 133 together enclose a doorway 134. The first front panel 131 is connected to all of the wall panels 20 of one side wall 15, thereby strengthening the connection and fixation of all of the wall panels 20 on one side wall 15. The second front panel 132 is connected to all of the wall panels 20 of the other side wall 15, thereby strengthening the connection and fixation of all of the wall panels 20 on the other side wall 15. The crossbeam 133 is connected to the wall panel 20 of the side wall 15 closest to the car roof 12 and is connected to the car roof 12, thereby securing the first and second front panels 131, 132 to the car roof 12 and strengthening the connection and fixation of the wall panel 20 of the side wall 15 closest to the car roof 12. Furthermore, in one embodiment, the crossbeam 133 can also be used to mount electrical components of the elevator.

[0052] See also Figure 10 In one embodiment, the wall panel 20 closest to the car floor 11 is spaced apart from the car floor 11, thereby forming a vent 111 in the gap between the wall panel 20 and the car floor 11, thereby enhancing air circulation within the car. Furthermore, the car includes a spacer block 40 that connects the wall panel 20 closest to the car floor 11 to the car floor 11, thereby securing the connection between the wall panel 20 and the car floor 11.

[0053] Specifically, see Figure 11 The pad 40 includes a fixing plate 41 and a pad 42. The fixing plate 41 includes a connecting surface 411. The connecting surface 411 is connected to the car bottom 11 and abuts against the wall panel 20 closest to the car bottom 11. Specifically, the fixing plate 41 is connected to the side of the car bottom 11 by bolts. At the same time, the connecting surface 411 of the fixing plate 41 abuts against the first flange 231 of the wall panel 20 closest to the car bottom 11. In this way, when the wall panel 20 closest to the car bottom 11 is installed, the wall panel 20 can be preliminarily positioned. Furthermore, the pad 42 is fixed on the connecting surface 411 and is arranged perpendicular to the connecting surface 411, that is, the pad 40 has a "T"-shaped structure as a whole. The pad 42 is arranged between the wall panel 20 closest to the car bottom 11 and the car bottom 11 and is connected to the wall panel 20 closest to the car bottom 11. Specifically, the pad 42 is provided with an oblong hole 421, which is communicated with the first connecting hole 2211 of the wall panel 20 closest to the car bottom 11. Therefore, the pad 40 and the wall panel 20 closest to the car bottom 11 can be connected and fixed by passing bolts or other connecting parts through the oblong hole 421 and the first connecting hole 2211. In addition, the oblong hole 421 can weaken the misalignment problem of the first connecting hole 2211 caused by processing errors, thereby making it easier to connect the two.

[0054] Optionally, in one embodiment, the decorative surfaces 211 of adjacent wall panels 20 along the direction from the car bottom 11 to the car top 12 are made of different materials. For example, in the side wall 15, from bottom to top, the wall panels 20 of each layer are made of different plastics or different metal materials. Similarly, in the rear wall 14, the wall panels 20 of each layer can also be made of different plastics or different metal materials, thereby forming a variety of decorative styles and enhancing the passenger experience.

[0055] Specifically, in one embodiment, the decorative surface 211 of the wall panel 20 closest to the car floor 11 is made of a wear-resistant material. Specifically, the wall panel 20 closest to the car floor 11 can be made entirely of a wear-resistant material, or the decorative surface 211 of the wall panel 20 closest to the car floor 11 can be covered with a wear-resistant material. Furthermore, wear-resistant materials include, but are not limited to, wear-resistant plastics such as polymer plastics, wear-resistant rubber, or wear-resistant metals such as stainless steel, or ceramic materials. This effectively reduces scratches on the lower wall panel 20 caused by bumps and kicks, thereby improving the car's scratch resistance. Furthermore, the height of the wall panel 20 closest to the car floor 11 is no greater than 700 mm, thereby covering the height of the cart while controlling costs. Furthermore, when the lowest wall panel 20 is made of a wear-resistant material, the other wall panels 20 can be made of other fine materials, thereby ensuring the car's scratch resistance while also enhancing its aesthetic appearance.

[0056] See also Figure 1 as well as Figure 4 A reinforcing beam 30 is further provided on the side of the panel 21 facing away from the decorative surface 211. The reinforcing beam 30 is arranged parallel to the car bottom 11. Specifically, the two ends of the reinforcing beam 30 are respectively connected to the two short sides 222 of the wall panel 20, thereby further strengthening the strength of the wall panel 20 and further improving the structural strength of the car.

[0057] Furthermore, the above-mentioned car comprises the following steps during assembly:

[0058] S1: Install the front wall 13. Specifically, use bolts or other connectors to fix the first front plate 131 and the second front plate 132 to the car bottom 11, and then use bolts or other connectors to fix the crossbeam 133 above the first front plate 131 and the second front plate 132 of the front wall 13.

[0059] S2: Install the wall panel 20 closest to the car floor 11 (i.e., the lowest level). Specifically, first securely connect the fixing plate 41 of the cushion block 40 to the frame of the car floor 11 using connectors. Then, within the car, bring the long side 221 of the wall panel 20 on one side (e.g., the right side) of the sidewall 15 into contact with the pad 42 of the cushion block 40. The flange of the wall panel 20 contacts the fixing plate 41 of the pad 40 to prevent the wall panel 20 from falling into the shaft. Align the first connecting hole 2211 of the long side 221 with the oblong hole 421 of the pad 42 and the connecting hole on the frame of the car floor 11. Then, secure the three together using connectors. Furthermore, if the bottom wall panel 20 is relatively small, one can stand directly inside the car and reach into the hoistway with both hands, secure the nut with one hand, and with the other hand, insert the connector through the first connecting hole 2211, the oblong hole 421, and the connecting hole on the car bottom 11 frame, and then connect it to the nut to secure the bottom wall panel 20, the spacer 40, and the car bottom 11. If the bottom wall panel 20 is relatively large and it is not possible to simultaneously insert both hands into the hoistway while standing inside the car to secure it, one can first install the nut through the connecting hole on the car bottom 11 frame (for example, by welding or gluing the nut), then insert the connector through the first connecting hole 2211, the oblong hole 421, and the nut inside the car, thus securing the bottom wall panel 20, the spacer 40, and the car bottom 11. The bottom wall panel 20 can then be secured to the front wall 13 through the second connecting hole on the short side 222 of the wall panel 20. The other side (for example, the left side) of the wall panel 20 can then be installed in the same manner. The first connecting holes 2211 of the long sides 221 of the wall panel 20 of the rear wall 14 are then connected and fixed to the frame of the car platform 11. The third connecting holes 2111 on both sides of the decorative surface 211 of the wall panel 20 of the rear wall 14 are aligned with the second connecting holes 2221 of the short sides 222 of the left and right sidewalls 15, respectively, and fixed via connectors, thus completing the installation of the bottom wall panel 20. The installation order can be adjusted. For example, in another embodiment, the left sidewall 15 panel can be installed first, followed by the right sidewall 15 panel.

[0060] S3: Install the middle wall panels 20. Following the method in step S2, inside the car, use tools to climb up, reach into the hoistway from inside the car to connect and secure the wall panels 20. The upper wall panels 20 are directly connected and secured to the corresponding connection holes of the lower wall panels 20. The height of the middle wall panels 20 must not exceed the maximum size that can be installed in the car. The empirical value is 620mm.

[0061] S4: Install the top wall panel 20. The installation method is similar to that of the middle wall panel 20, except that the short side 222 of the wall panel 20 of the side wall 15 needs to be connected to the crossbeam 133, and the upper long sides 221 of the wall panel 20 of the side wall 15 and the wall panel 20 of the rear wall 14 are both connected and fixed to the car roof 12 using the first connecting holes.

[0062] An embodiment of the present application further provides an elevator. Specifically, the elevator of one embodiment is characterized by comprising the above-mentioned elevator car.

[0063] In the aforementioned car, the rear wall 14 and two side walls 15 comprise at least two wall panels 20 connected sequentially from the car floor 11 to the car ceiling 12. This effectively reduces the height of each wall panel 20. During assembly, workers can stand on the car floor 11 and install the wall panels 20 layer by layer from bottom to top to complete the assembly of the side walls 15 and rear wall 14. This eliminates the need to enter the hoistway, thus reducing the risk of falling and improving safety. Furthermore, the size of each wall panel 20 is significantly reduced compared to conventional wall panels, increasing the strength of each individual wall panel 20. Furthermore, the edges of the panels 21 are each provided with a bent edge 22, reinforcing each wall panel 20 and improving the overall strength of the car while maintaining cost. Furthermore, adjacent wall panels 20 are connected by a bent edge 22, which extends away from the decorative surface 211. This allows for the connection and fixation of each wall panel 20 without affecting the appearance of the decorative surface 211. This eliminates the need for additional reinforcement structures such as columns, simplifying the structural design, saving material costs, and shortening installation time. Moreover, after assembly, the joints between two adjacent wall panels 20 on the same side are horizontal. When the car is equipped with handrails and other components, they can be installed on the same wall panel 20, avoiding interference between the fixed legs of handrails and other components and the joints of the wall panels 20, thereby improving the compatibility of the car.

[0064] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
