Description

Technical Field

[0001] This application relates to the technical field of elevator cars, and in particular to a standardized circular arc car wall. Background Technology

[0002] In the elevator manufacturing industry, the elevator car, as a crucial component carrying passengers and goods, has always been a focus of industry attention in terms of design and manufacturing processes. As people's demands for the aesthetics and comfort of elevators continue to increase, the design of the car's interior walls has gradually diversified. The curved surface design, with its smooth lines and unique visual effect, is increasingly favored by the market. This design not only enhances the overall quality of the elevator but also increases the sense of space inside the car to a certain extent, providing passengers with a more comfortable riding experience. Furthermore, curved car interior walls are widely used in some high-end commercial buildings and luxury residences, becoming an important element in enhancing the building's prestige.

[0003] Previously, when a curved surface was required on the inner wall of an elevator car, the common method was to shape the curved surface at the ends of the wooden boards. This method involved cutting and processing the wooden boards according to design requirements, and then using specialized woodworking tools and equipment to shape the desired curved shape at the ends, either manually or mechanically. However, during mass production in a factory, the inherent properties of the wood and various factors during processing, such as tool wear and equipment precision errors, easily lead to inaccuracies in the shaped curved surface, making it difficult to guarantee product consistency and precision. Furthermore, during transportation, the relatively soft wood boards are easily damaged by impacts and pressure, affecting product quality and appearance, and increasing production and maintenance costs. Therefore, further improvements are needed. Utility Model Content

[0004] To address the above issues, this application provides a standardized circular arc car wall.

[0005] This application provides a standardized arc-shaped car wall, which adopts the following technical solution: A standardized arc-shaped car wall includes at least one arc plate, two straight plates, and an installation assembly for mounting the arc plate and the straight plates. The two straight plates are disposed on both sides of the arc plate. The installation assembly includes two connecting parts that are respectively fixedly connected to both sides of the arc plate. The connecting parts have a slot on the end face near the straight plate, and the straight plate has a snap-fit ​​part that is inserted into the slot.

[0006] By adopting the above technical solution, the curved car wall is divided into a standardized component structure consisting of a curved plate and a straight plate. The installation component is configured to include two connecting parts that are respectively fixedly connected to both sides of the curved plate, and a slot is opened on the end face of the connecting part near the straight plate. At the same time, the straight plate protrudes and is engaged in the slot, so that the curved plate and the straight plate can be connected by the engagement of the slot and the engagement part. This connection method changes the curved car wall into a standardized component structure, reduces the method of forming a curved surface at the end of the wooden board, reduces the possibility of errors during batch processing in the factory, and the standardized component structure is less prone to damage during transportation compared to the structure with a curved surface formed at the end of the wooden board.

[0007] Preferably, it also includes a covering layer covering the inner surfaces of the arc plate and the two straight plates.

[0008] By adopting the above technical solution, a covering layer can be provided to reduce the exposure of the connection seam between the arc plate and the two straight plates, thereby improving the aesthetics.

[0009] Preferably, the slot is filled with adhesive, which solidifies to form an adhesive layer.

[0010] By adopting the above technical solution, the adhesive is filled into the slot and solidified to form an adhesive layer, which can enhance the stability of the connection between the arc plate and the straight plate, making the connection between the two tighter and more reliable, effectively avoiding loosening or separation during use. Compared with simple snap-fit ​​connection, it further improves the stability and durability of the overall structure of the standardized arc car wall.

[0011] Preferably, the connecting part has protruding ridges on the inner surface of the slot, and a plurality of ridges are spaced apart along the width direction of the connecting part.

[0012] By adopting the above technical solution, several protruding ridges are provided on the inner surface of the connecting part located in the slot, which are spaced apart along the width direction of the connecting part. This increases the contact area between the inner surface of the slot and the connecting part, making the connection between the connecting part and the slot tighter. At the same time, the protruding ridges can also play a certain positioning role, which helps the connecting part to accurately engage in the slot. Furthermore, when the slot is filled with adhesive, the protruding ridges can increase the adhesion area between the adhesive and the inner surface of the slot, making the adhesive layer bonded to the slot more firmly, thereby improving the stability and reliability of the connection between the arc plate and the straight plate.

[0013] Preferably, the connecting portion has reinforcing ribs protruding from the side wall away from the straight plate.

[0014] By adopting the above technical solution, reinforcing ribs protrude from the side wall of the connecting part away from the straight plate, which can enhance the structural strength of the connecting part and further improve the overall stability and reliability of the arc-shaped car wall.

[0015] Preferably, the arc plate is made of steel plate, the straight plate is made of wood, and the outer surface of the arc plate is provided with a plurality of support members.

[0016] By adopting the above technical solution, the arc plate is made of steel plate and the straight plate is made of wood plate, which makes it easier to take advantage of the different characteristics of steel plate and wood plate, and reduce costs while ensuring the strength of the car wall structure. Since the arc plate is made of steel plate, when it has the same strength as the template, the required thickness is thinner. In order to fit closely, support members are set for support to reduce the impact of hollowness.

[0017] Preferably, the connecting part includes a first connecting plate fixed to the arc plate, a second connecting plate perpendicular to the first connecting plate, and a third connecting plate. The width direction of the first connecting plate is perpendicular to the width direction of the straight plate, and the width directions of the second connecting plate and the third connecting plate are both parallel to the width direction of the straight plate. The surfaces of the second connecting plate and the third connecting plate that are close to each other form a groove.

[0018] By adopting the above technical solution, the connecting part adopts a structure of a first connecting plate, a second connecting plate and a third connecting plate. The first connecting plate is fixed to the arc plate, and its width direction is perpendicular to the width direction of the straight plate, providing a stable foundation for the connection. The width directions of the second connecting plate and the third connecting plate are parallel to the width direction of the straight plate, and the surfaces of the two are close to each other to form a groove, which can easily engage the engaging part of the straight plate and realize the effective connection between the arc plate and the straight plate.

[0019] Preferably, the second connecting plate is flush with the outer surface of the straight plate, and the width of the second connecting plate is greater than or equal to the width of the third connecting plate.

[0020] By adopting the above technical solution, the outer surface of the second connecting plate is flush with the outer surface of the straight plate, which makes the outer surface of the standardized arc-shaped car wall smoother, improving the overall aesthetics and smoothness. At the same time, the width of the second connecting plate is greater than or equal to the width of the third connecting plate, which enhances the structural stability and connection strength of the connection, better connects the arc plate and the straight plate together, ensures the overall structural stability of the standardized arc-shaped car wall, and reduces loosening or damage caused by weak connections.

[0021] Preferably, the third connecting plate is provided in a plurality of portions spaced apart along the width direction of the first connecting plate.

[0022] By adopting the above technical solution, the third connecting plate is spaced out with several slots along the width direction of the first connecting plate, thereby forming multiple slots. This enhances the structural stability and strength of the connecting part, makes the connection between the arc plate and the straight plate more stable, and further improves the overall stability and reliability of the standardized arc car wall.

[0023] Preferably, the mounting assembly further includes bolts threaded through the second connecting plate and the third connecting plate, the bolts being inserted into the snap-fit ​​portion.

[0024] By adopting the above technical solution and adding bolts, the connection strength between the arc plate and the straight plate can be further strengthened, making the structure of the standardized arc car wall more stable, effectively reducing the separation or loosening of the arc plate and the straight plate during use, and improving the overall stability and reliability of the standardized arc car wall.

[0025] In summary, this application has the following beneficial effects: 1. The curved car wall is divided into three sections, with straight plates at both ends and a curved end. These sections are connected by installation components to form a standardized component structure, avoiding the need to form a curved surface at the end of the wooden board and reducing errors during mass production in the factory. 2. The standardized component structure reduces the risk of damage during car wall transportation, as each component can be packaged and transported independently; 3. The curved plate and the straight plate are connected by mounting components, which improves product consistency and precision, and reduces production and maintenance costs.

[0028] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0029] This application discloses a standardized circular arc car wall.

[0030] Example 1: A standardized circular arc sedan wall, as referenced Figure 1 , Figure 2It includes at least one arc plate 1, two straight plates 2, a mounting assembly 3, and a covering layer 4. The two straight plates 2 are disposed on both sides of the arc plate 1. The mounting assembly 3 is used to install the arc plate 1 and the straight plates 2. The covering layer 4 covers the inner surfaces of the arc plate 1 and the two straight plates 2. This structure makes the car wall a standardized component structure, which is convenient for processing and transportation, and can also improve the overall precision and quality.

[0031] In this embodiment, the arc plate 1 is made of steel plate, which has good strength and stability, ensuring the overall structure of the car wall. In practical applications, other metal plates with similar properties, such as aluminum plates, can be used to replace the steel plate. The surface of the steel plate can be treated, such as by painting or galvanizing, to improve its rust and corrosion resistance. Several support members 11 are provided on the surface of the arc plate 1 away from the covering layer 4. The support members 11 can be triangular reinforcing ribs, which enhance the structural strength of the arc plate 1 and prevent deformation during use. Of course, the support members 11 can also adopt other shapes and structures, such as columnar support columns. These support members 11 are fixed to the arc plate 1 by welding to ensure the firmness of the connection.

[0032] In this embodiment, the straight panel 2 is made of wood, which has a good texture and decorative properties, creating a warm and comfortable atmosphere inside the car. In some cases, materials such as plastic panels or composite panels can also be used instead of wood. The surface of the wood panel can be sanded, painted, etc., to make it smoother and more beautiful. The two straight panels 2 are located on both sides of the arc panel 1 and are connected to the arc panel 1 through the mounting assembly 3.

[0033] Reference Figure 2 , Figure 3The mounting assembly 3 includes two connecting parts fixedly connected to both sides of the arc plate 1. The connecting parts are integrally formed with the arc plate 1 and are used to connect the arc plate 1 and the straight plate 2. Each connecting part includes a first connecting plate 31 fixed to the arc plate 1, a second connecting plate 32 perpendicular to the first connecting plate 31, and a third connecting plate 33. The width direction of the first connecting plate 31 is perpendicular to the width direction of the straight plate 2, while the width directions of the second connecting plate 32 and the third connecting plate 33 are parallel to the width direction of the straight plate 2. A groove 34 is formed on the surfaces of the second connecting plate 32 and the third connecting plate 33 that are close to each other. The second connecting plate 32 is flush with the outer surface of the straight plate 2, and the width of the second connecting plate 32 is greater than or equal to the width of the third connecting plate 33. The first connecting plate 31 can be fixed to the arc plate 1 by welding or bolts 37 to ensure the stability of the connection. The surfaces of the second connecting plate 32 and the third connecting plate 33 that are close to each other form a slot 34. The straight plate 2 has a protruding engaging part 5 that is fitted into the slot 34. The engaging part 5 and the slot 34 are tightly fitted together, which can achieve preliminary positioning and connection. For example, the engaging part 5 can be a protruding structure integrally formed at the end of the straight plate 2, and its shape is adapted to the slot 34.

[0034] It should be noted that the third connecting plate 33 may be provided in several intervals along the width direction of the first connecting plate 31 to form multiple slots 34, thereby improving the connection strength between the arc plate 1 and the straight plate 2.

[0035] Adhesive is filled into the slot 34, and after solidification, it forms an adhesive layer 6. The function of the adhesive layer 6 is to further strengthen the connection between the straight plate 2 and the curved plate 1. The adhesive can be a strong and durable glue such as epoxy resin. A protruding ridge 35 protrudes from the inner surface of the slot 34 at the connection part. Several ridges 35 are spaced apart along the width direction of the connection part, and are specifically located on the surface of the third connection near the second connecting plate 32. The function of the ridges 35 is to increase the contact area between the adhesive and the connection part, improving the bonding effect. The ridges 35 can be strip-shaped protrusions, and their height and width can be designed according to the actual situation.

[0036] Furthermore, a reinforcing rib 36 protrudes from the side wall of the connecting portion away from the straight plate 2. The reinforcing rib 36 can be a triangular rib, the function of which is to enhance the structural strength of the connecting plate and prevent deformation during use. The reinforcing rib 36 is fixed to the connecting plate by welding to ensure the firmness of the connection.

[0037] The arc-shaped plate 1 is made of steel, and the straight plate 2 is made of wood. Several support members 11 are provided on the outer surface of the arc-shaped plate 1. The connecting part includes a first connecting plate 31 fixed to the arc-shaped plate 1, a second connecting plate 32 perpendicular to the first connecting plate 31, and a third connecting plate 33. The implementation principle of a standardized arc-shaped car wall in this embodiment is as follows: The arc-shaped car wall is designed as a three-section structure, consisting of straight plates 2 at both ends and an arc-shaped plate 1 in the middle, connected by an installation component 3. This standardized component structure avoids the method of forming arc surfaces at the ends of wooden boards, reducing errors during batch processing in factories and improving product consistency and precision. Simultaneously, due to the combination of steel and wood plates, the steel plate has higher strength and is less prone to damage during transportation, while the wood, although softer, can also be effectively protected from damage through proper packaging and transportation methods. Furthermore, the design of the slots 34, snap-fit ​​parts 5, adhesive layer 6, protruding ribs 35, reinforcing ribs 36, and bolts 37 in the installation component 3 further enhances the connection strength and stability of the car wall, improving the overall quality and service life of the product, representing a significant improvement and enhancement compared to existing technologies.

[0038] Example 2: Reference Figure 4 The difference from Embodiment 1 is that the mounting assembly 3 further includes bolts 37 threaded through the second connecting plate 32 and the third connecting plate 33, with the bolts 37 passing through the snap-fit ​​portion 5. The function of the bolts 37 is to further secure the straight plate 2 and the arc plate 1, reducing the likelihood of loosening during use. High-strength alloy steel bolts 37 can be used to ensure the reliability of the connection.

[0039] 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.
