Description

Technical Field

[0001] This utility model relates to the field of home appliance display panel housing technology, and specifically discloses a home appliance display panel anti-deformation injection molded housing. Background Technology

[0002] In the structural composition of home appliances, the display panel is a key component for human-computer interaction and information display. The display panel typically requires a molded housing for fixation and protection. As the mounting carrier for the display panel, the structural stability of the molded housing directly affects the assembly precision, display effect, and overall lifespan of the home appliance.

[0003] Currently, most commercially available home appliance display panel injection-molded shells are made from a single plastic material using injection molding. However, in actual use, these injection-molded shells are prone to deformation. The main reasons include the following: First, during the injection molding process, due to the shrinkage characteristics of the plastic material itself, as well as improper mold design and molding process parameter control, internal stress can easily be generated after the shell cools and solidifies, leading to warping, dents, and other deformations during later use. Second, home appliances are affected by changes in ambient temperature during daily use. The thermal expansion and contraction characteristics of the plastic material cause uneven expansion and contraction deformation in different parts of the shell, which can lead to a decrease in structural stability after long-term use. Third, during installation, disassembly, or transportation of home appliances, the shell may be subjected to external impacts or compression. Traditional shells lack sufficient structural strength and cannot effectively resist these external forces, resulting in deformation. Therefore, a deformation-resistant injection-molded shell for home appliance display panels is needed to solve the above problems. Utility Model Content

[0004] This utility model proposes an anti-deformation injection molded shell for home appliance display panels. Through the coordinated work of horizontal reinforcing ribs, vertical reinforcing ribs, grid-type reinforcing ribs, rubber protective protrusions, and anti-deformation frame, the injection molded shell comprehensively improves the anti-deformation ability from both internal structural reinforcement and external protection, effectively solving the problem of easy deformation of traditional shells.

[0005] This utility model is implemented as follows: a deformation-resistant injection-molded shell for a home appliance display panel includes a shell body. The inner wall of the shell body is provided with multiple transverse and longitudinal reinforcing ribs. The distance between two adjacent transverse and longitudinal reinforcing ribs is 3cm. The surface of the transverse reinforcing ribs away from the inner wall of the shell body is provided with a grid-type reinforcing rib with a height of 1.2mm. The outer surface of the shell body is provided with multiple rubber protective protrusions. The multiple rubber protective protrusions are evenly distributed and are hemispherical. The edge of the shell body is provided with a deformation-resistant frame.

[0006] As a preferred embodiment of the anti-deformation injection molded housing for a home appliance display panel according to this utility model, the anti-deformation frame is arranged perpendicularly to the housing body, and the thickness of the anti-deformation frame is 2mm and the height is 10mm.

[0007] As a preferred embodiment of the anti-deformation injection molded shell for a home appliance display panel according to this utility model, the transverse reinforcing ribs, longitudinal reinforcing ribs, and grid-type reinforcing ribs are integrally injection molded with the shell body.

[0008] As a preferred embodiment of the present invention, the multiple rubber protective protrusions are distributed in a matrix on the outer surface of the outer shell body.

[0009] As a preferred embodiment of the present invention, the rubber protective protrusion is fixed to the outer surface of the housing body by vulcanization bonding.

[0010] As a preferred embodiment of the present invention, the anti-deformation injection molded housing for a home appliance display panel is made of ABS plastic material through injection molding.

[0011] The beneficial effects of this utility model are:

[0012] Multiple transverse and longitudinal reinforcing ribs on the inner wall of the outer casing can initially prevent deformation of the casing. The grid structure of the mesh-type reinforcing ribs further increases the structural strength and rigidity of the transverse reinforcing ribs. The hemispherical rubber protective protrusions evenly distributed on the outer surface of the casing can absorb the impact force by the elastic deformation of the rubber material when the casing is subjected to external impact or compression, thus playing a buffering role. The anti-deformation frame at the edge of the casing can reinforce the edge area, enhance the structural strength of the casing edge, resist the warping and deformation tendency of the edge under stress or temperature changes, and ensure a good fit between the casing edge and the display panel. Through the synergistic work of the above structures, this injection-molded casing comprehensively improves its anti-deformation ability from both internal structural reinforcement and external protection, effectively solving the problem of easy deformation of traditional casings.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0020] Please see Figure 1-4 A deformation-resistant injection-molded housing for a home appliance display panel includes a housing body 1. The inner wall of the housing body 1 is provided with multiple transverse reinforcing ribs 2 and longitudinal reinforcing ribs 4. The distance between two adjacent transverse reinforcing ribs 2 and two adjacent longitudinal reinforcing ribs 4 is 3cm. The surface of the transverse reinforcing ribs 2 away from the inner wall of the housing body 1 is provided with a grid-type reinforcing rib 3. The height of the grid-type reinforcing rib 3 is 1.2mm. The outer surface of the housing body 1 is provided with multiple rubber protective protrusions 5. The multiple rubber protective protrusions 5 are evenly distributed and are hemispherical. The edge of the housing body 1 is provided with a deformation-resistant frame 6.

[0021] In this embodiment, multiple transverse reinforcing ribs 2 and longitudinal reinforcing ribs 4 are provided on the inner wall of the outer shell body 1 to initially prevent deformation of the outer shell body 1. Adjacent transverse reinforcing ribs 2 and adjacent longitudinal reinforcing ribs 4 are evenly distributed at a spacing of 3 cm, effectively improving the overall bending and tensile resistance of the outer shell body 1.

[0022] The mesh-type reinforcing rib 3 further increases the structural strength and rigidity of the transverse reinforcing rib 2 with its mesh structure. When the transverse reinforcing rib 2 is under stress, the mesh-type reinforcing rib 3 can distribute the force to a larger area, preventing the transverse reinforcing rib 2 from bending or breaking due to excessive local stress, thereby ensuring the supporting effect of the transverse reinforcing rib 2 on the entire shell.

[0023] The hemispherical rubber protective protrusions 5, evenly distributed on the outer surface of the outer shell body 1, absorb the impact force through the elastic deformation of the rubber material when the shell is subjected to external impact or compression, thus acting as a buffer. The anti-deformation frame 6 at the edge of the outer shell body 1 reinforces the edge area. It enhances the structural strength of the shell edge, resists the warping and deformation tendency of the edge under stress or temperature changes, and ensures a good fit between the shell edge and the display panel. Through the coordinated work of the above structures, this injection-molded shell comprehensively improves its anti-deformation ability from both internal structural reinforcement and external protection, effectively solving the problem of easy deformation of traditional shells.

[0024] As a technical optimization of this utility model, the anti-deformation frame 6 is set perpendicularly to the outer shell body 1, and the thickness of the anti-deformation frame 6 is 2mm and the height is 10mm.

[0025] In this embodiment, the vertical arrangement allows the anti-deformation frame 6 and the outer shell body 1 to form a stable right-angle support structure, which greatly enhances the bending resistance of the edge and effectively resists edge warping caused by external forces or temperature changes.

[0026] As a technical optimization of this utility model, the transverse reinforcing rib 2, the longitudinal reinforcing rib 4, the grid-type reinforcing rib 3 and the outer shell body 1 are integrated injection molded structures.

[0027] In this embodiment, the integrated molding allows each reinforcing rib to form a seamless integral structure with the outer shell body 1, avoiding gaps or weak points that may exist in the assembly connection. This allows forces to be transmitted more evenly among the components. When the shell is subjected to external forces or temperature changes that generate stress, the stress can be dispersed and dissipated through the overall structure, greatly improving the deformation resistance of the entire shell and reducing the risk of local breakage or deformation caused by weak connections between components.

[0028] As a technical optimization of this utility model, multiple rubber protective protrusions 5 are distributed in a matrix on the outer surface of the outer shell body 1.

[0029] In this embodiment, the matrix distribution allows the rubber protective protrusions 5 to work together from multiple points when the shell is subjected to external impact or compression, distributing the impact force evenly over a larger area of ​​the shell surface, thus avoiding excessive local force concentration that could damage the shell.

[0030] As a technical optimization of this utility model, the rubber protective protrusion 5 is fixed to the outer surface of the outer shell body 1 by vulcanization bonding.

[0031] In this embodiment, vulcanization bonding enables the rubber protective protrusion 5 to form a stable bond with the outer shell body 1, which is not easy to fall off due to external impact, friction or long-term use, thus ensuring the durability of the protective structure.

[0032] As a technical optimization of this utility model, the outer shell body 1 is injection molded from ABS plastic material.

[0033] In this embodiment: ABS plastic has good mechanical properties, with moderate strength and rigidity, which can meet the requirements of the shell body 1 for basic support capacity, making it less likely to be deformed or damaged by slight force in daily use.

[0034] The working principle and usage process of this utility model: Multiple transverse reinforcing ribs 2 and longitudinal reinforcing ribs 4 are provided on the inner wall of the outer shell body 1 to initially prevent deformation of the outer shell body 1. The adjacent transverse reinforcing ribs 2 and adjacent longitudinal reinforcing ribs 4 are evenly distributed at a spacing of 3cm, which can disperse the transverse force on the outer shell body 1. The two work together to effectively improve the overall bending and tensile resistance of the outer shell body 1 and reduce deformation caused by uneven force.

[0035] The transverse reinforcing rib 2 has a mesh-type reinforcing rib 3 on the side of the outer shell body 1 away from the inner wall, with a height of 1.2mm. Its mesh structure further increases the structural strength and rigidity of the transverse reinforcing rib 2. When the transverse reinforcing rib 2 is under stress, the mesh-type reinforcing rib 3 can distribute the force to a larger area, avoiding excessive local stress on the transverse reinforcing rib 2, which may cause bending or breakage, thereby ensuring the supporting effect of the transverse reinforcing rib 2 on the entire shell.

[0036] The hemispherical rubber protective protrusions 5 evenly distributed on the outer surface of the outer shell 1 absorb the impact force by utilizing the elastic deformation of the rubber material when the shell is subjected to external impact or compression, thus playing a buffering role. This buffering reduces the direct transmission of external force to the outer shell 1, reducing the possibility of the outer shell 1 deforming due to external force. At the same time, multiple evenly distributed rubber protective protrusions 5 make the buffering effect more uniform and stable.

[0037] The anti-deformation frame 6 at the edge of the outer casing 1 reinforces the edge area. It enhances the structural strength of the outer casing edge, resists warping and deformation tendencies caused by stress or temperature changes, ensures a good fit between the outer casing edge and the display panel, and guarantees the installation stability of the display panel. Through the coordinated work of the above structures, this injection-molded outer casing comprehensively improves its anti-deformation capability from both internal structural reinforcement and external protection, effectively solving the problem of easy deformation of traditional outer casings.
