Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, and in particular to an elastic pressing structure on a main body. Background Technology

[0002] With the popularization of modern home appliances and smart devices, control panels have become an important interface for users to interact with devices. On these control panels, buttons, as one of the main input methods, play a key role in transmitting user commands. Currently, most home appliance control panels and smart devices on the market typically use microswitches or other similar mechanical structures for their button structures. The design of microswitches often requires complex assembly processes and additional supporting structural components, which not only increases production costs but also places high demands on the assembly process. This may also lead to poor button reset performance or easy damage during long-term use. Utility Model Content

[0003] In response to the problems raised in the background art, the purpose of this utility model is to propose an elastic pressing structure on the main body, which can be used for pressing without the need for another structural component, and can be repeatedly pressed, has good repositioning, is not easily deformed, and reduces assembly difficulty and cost.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] An elastic pressing structure on a main body, the elastic pressing structure including a pressing structure and two elastic connecting arms;

[0006] The main body has an opening, and the pressing structure is disposed at the opening;

[0007] One end of the elastic connecting arm is connected to the pressing structure, and the other end of the elastic connecting arm is connected to the main body;

[0008] The connection points of the two elastic connecting arms to the pressing structure are located at opposite ends of the pressing structure, and the connection point of the elastic connecting arm to the main body is located on one side of the connection point of the other elastic connecting arm to the pressing structure;

[0009] The pressing structure is used to contact the button after being pressed to form a pressing operation.

[0010] Preferably, the main body, the pressing structure, and the elastic connecting arm are all made of plastic.

[0011] Preferably, a support position is provided between the pressing structure and the button, and the support position is used to limit the pressing range of the pressing structure.

[0012] Preferably, the pressing structure is parallel to the main body.

[0013] Preferably, the cross-sectional shape of the pressing structure is square.

[0014] Preferably, the cross-sectional dimension of the elastic connecting arm is smaller than the cross-sectional dimension of the pressing structure.

[0015] Preferably, the elastic connecting arm includes a first straight arm portion, a second straight arm portion, and a turning portion;

[0016] One end of the first straight arm is connected to the main body, and the other end is connected to one end of the second straight arm through a bend. The other end of the second straight arm is connected to the pressing structure through a bend.

[0017] Preferably, the mounting part is integrally formed with the main body.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] By adopting a flexible pressing structure, the complex assembly process and supporting structures of traditional button mechanisms are effectively simplified, reducing production costs and improving the durability and lifespan of the buttons. The flexible connecting arm design provides smooth pressing feedback, avoiding common microswitch problems such as poor reset or easy damage, ensuring that the button consistently returns to its original shape during repeated pressing. Furthermore, the J-shaped hook-type flexible connecting arm can reasonably distribute the force during pressing, optimizing the tactile feedback of the button, reducing deformation or damage caused by stress concentration, and improving the smoothness and comfort of pressing operation. The use of plastic materials further enhances the structure's elasticity, fatigue resistance, and production efficiency, thereby improving the overall user experience and ensuring higher product reliability and economy.

[0026] With the popularization of modern home appliances and smart devices, control panels have become an important interface for users to interact with devices. On these control panels, buttons, as one of the main input methods, play a key role in transmitting user commands. Currently, most home appliance control panels and smart devices on the market typically use microswitches or other similar mechanical structures for their button structures. The design of microswitches often requires complex assembly processes and additional supporting structural components, which not only increases production costs but also places high demands on the assembly process. This may also lead to poor button reset performance or easy damage during long-term use.

[0027] Therefore, an elastic pressing structure on the main body is proposed, such as Figure 1 and Figure 2 As shown, the elastic pressing structure 1 includes a mounting part, a pressing structure 1, and two elastic connecting arms 2;

[0028] The mounting part is provided with a through hole, and the pressing structure 1 is disposed in the through hole;

[0029] One end of the elastic connecting arm 2 is connected to the pressing structure 1, and the other end of the elastic connecting arm 2 is connected to the mounting part;

[0030] The connection points of the two elastic connecting arms 2 and the pressing structure 1 are located at opposite ends of the pressing structure 1. The connection point of the elastic connecting arm 2 and the main body is located on one side of the connection point of the other elastic connecting arm 2 and the pressing structure 1. When an external force is applied to the pressing structure 1, the pressing structure 1 moves relative to the main body. When the external force disappears, the pressing structure 1 returns to its original position under the elastic action of the elastic connecting arm 2.

[0031] The pressing structure 1 is used to contact the button after being pressed to form a pressing operation.

[0032] The main body can be the outer shell of a device or apparatus, such as the outer shell of a computer case or the panel shell used to connect the buttons. The main body provides fixed support for the elastic connecting arm 2, ensuring that the entire pressing structure 1 can operate stably. The main body has an opening for accommodating the pressing structure 1 and the elastic connecting arm 2. The elastic connecting arm 2 is an elastic component that connects the pressing structure 1 and the main body. It can be made of elastic materials (such as spring steel, elastic plastic, etc.). The elastic connecting arm 2 connects the pressing structure 1 and the main body, transmits the pressing force, and after pressing, it elastically returns to its original shape, allowing the pressing structure 1 to reset. The number and design of the elastic connecting arms 2 can determine the smoothness and stability of the pressing operation. The opening provides a space for the pressing structure 1 to move within the opening and realize the pressing operation.

[0033] The pressing structure 1 can be made of different materials, such as plastic, silicone, or metal. The choice of material affects the comfort, durability, and production cost of pressing. Choosing a suitable material can improve the user experience or reduce manufacturing costs based on product positioning. The size of the opening should not be too large to avoid pressing into an off-center position, which could lead to misalignment or damage to the elastic connecting arm 2 or the pressing structure 1. Preferably, the size of the opening can be between 6-10cm, the cross-sectional dimension of the pressing structure 1 can be set to 3cm, and the cross-sectional dimension of the elastic connecting arm 2 can be 1.5cm. The size of the pressing structure 1 and the cross-sectional dimension of the elastic connecting arm 2 can be designed according to the pressing frequency and force to adjust the load-bearing capacity of the elastic connecting arm 2 and the pressing structure 1.

[0034] The two elastic connecting arms 2 are designed with "J"-shaped hooks. This hook design can effectively distribute the force applied to the thin arms when pressing. Due to the hook-shaped bending structure, the elastic pressing structure can deform within a small range when pressed, producing a smoother tactile feedback. The thin arms with the hook-shaped structure can bend or compress more easily when subjected to pressure, while also ensuring that the elastic pressing structure can smoothly return to its original position after the user releases the pressure. Compared to a connecting arm extending straight from the main body and connecting to the pressing structure 1, the J-shaped hook makes the elastic pressing structure more ergonomic in its response. When pressed, the mechanical force is relatively dispersed, avoiding excessively direct impact. The hook-shaped design helps the elastic pressing structure maintain its stability and durability during repeated pressing. If it were a straight design, the thin arm might be more prone to premature fatigue or deformation with increasing pressing frequency, reducing the lifespan of the elastic pressing structure. If two straight thin arms extend directly from the center of the pressing structure 1 and connect to the main body, such a design would cause greater stress concentration during pressing. Due to the lack of a curved hook structure, the bending or deformation space of the thin arms is limited, which may cause the elastic pressing structure to become more rigid or generate excessive rebound force during pressing. Furthermore, the straight thin arms make it difficult to control the pressing depth, which may also make the elastic pressing mechanism more rigid, losing its smooth touch and appropriate feedback.

[0035] Preferably, the main body, the pressing structure 1, and the elastic connecting arm 2 are all made of plastic.

[0036] Specifically, plastic material has good elasticity and fatigue resistance, and can withstand multiple presses without easily deforming or being damaged, thus greatly extending the product's service life. The elastic connecting arm 2 provides appropriate rebound force, making the pressing feedback smooth and comfortable, which helps to enhance the user experience. In addition, plastic is relatively inexpensive and easy to mass-produce, which helps to reduce production costs.

[0037] Preferably, a support position is provided between the pressing structure 1 and the button, and the support position is used to limit the pressing range of the pressing structure 1.

[0038] A support is provided between the pressing structure 1 and the button. The support is designed to limit the pressing range of the pressing structure 1, thereby ensuring the accuracy and stability of the pressing action. Through the constraint of the support, the movement range of the pressing structure 1 on the button is controlled, avoiding over-pressing or misoperation. This not only effectively prevents button damage but also improves the user experience, ensuring consistent feedback with each press. Furthermore, the support prevents unnecessary shaking or offset during pressing, making button operation smoother and more reliable. Optionally, the support limits the pressing range to 0.2mm.

[0039] Preferably, the pressing surface of the pressing structure 1 is parallel to the surface of the main body.

[0040] Specifically, the parallel alignment of the pressing structure 1 with the main body makes the pressing action more stable and balanced. When the pressing structure 1 is parallel to the main body, it is easier for users to press, improving the user experience. In addition, the parallel design simplifies the manufacturing process, reduces complex angle adjustments or additional supports, thereby reducing production costs. It also optimizes the overall structural durability and production efficiency, preventing possible scratches due to the protrusion of the pressing structure 1.

[0041] Preferably, the cross-sectional shape of the pressing structure 1 is square.

[0042] The square cross-section of the pressing structure 1 provides a uniform pressing feel. The square shape allows for a wider contact surface and a more even distribution of force, thus avoiding discomfort or damage risks caused by concentrated local pressure. Furthermore, the square corner design helps improve pressing stability, enabling users to more accurately perceive the pressing area, enhancing operational comfort and accuracy. This shape also facilitates manufacturing and precise machining, helping to reduce production costs and improve consistency.

[0043] Preferably, the cross-sectional dimension of the elastic connecting arm 2 is smaller than the cross-sectional dimension of the pressing structure 1.

[0044] Specifically, the design of the elastic connecting arm 2 having a smaller cross-sectional dimension than the pressing structure 1 effectively controls the flexibility and force of the pressing action, ensuring that the elastic connecting arm 2 can undergo appropriate elastic deformation during the pressing process, avoiding excessive deformation or damage to the pressing structure 1. Furthermore, the smaller size of the elastic connecting arm 2 also ensures higher durability and response speed, thereby optimizing the quality of the pressing feedback. At the same time, the smaller cross-sectional dimension reduces the weight and volume of the elastic connecting arm 2, avoiding unnecessary space occupation and making the entire structure more compact and lightweight.

[0045] Preferably, in Figure 1 and Figure 2 In the middle, the elastic connecting arm 2 includes a first straight arm portion 21, a second straight arm portion 22, and a turning portion 23;

[0046] One end of the first straight arm 21 is connected to the main body, and the other end is connected to one end of the second straight arm 22 through the bend 23. The other end of the second straight arm 22 is connected to the pressing structure 1 through the bend 23.

[0047] The first straight arm 21 is connected to the main body at one end. Its main function is to fix and support a part of the elastic connecting arm 2. Since the first straight arm 21 is located on one side of the main body, it provides initial support and fixing force for the elastic connecting arm 2, so that the whole structure has a certain stability when pressed. The turning part 23 is the key part connecting the first straight arm 21 and the second straight arm 22, as well as the second straight arm 22 and the pressing structure 1. The turning part 23 changes direction so that the force can be better transmitted and ensures that the elastic connecting arm 2 can produce appropriate displacement or elastic deformation during the pressing process. Its function is to coordinate the movement relationship between the first straight arm 21 and the second straight arm 22 so that the pressing structure 1 can obtain an appropriate response when subjected to pressure. The second straight arm 22 is connected at one end to the turning part 23 and at the other end to the pressing structure 1. It is responsible for transmitting elastic deformation to the pressing structure 1. The length and stiffness of the second straight arm 22 directly affect the pressing feel and rebound effect of the pressing structure 1. Through elastic connection, the second straight arm 22 can return to its original shape after pressing, providing the rebound force of the elastic pressing structure. When force is applied to the elastic connecting arm 2, the straight arm can produce uniform elastic deformation, maintaining the simplicity of the structure and the expected mechanical properties. Compared with the curved arm, the straight elastic arm can provide consistent force feedback during pressing and rebound, avoiding unpredictable deformation or uneven deformation that may occur due to the curved shape.

[0048] Preferably, the mounting part is integrally formed with the main body.

[0049] Specifically, the mounting section is integrally molded with the main body, which reduces the installation space required for the elastic pressing structure and makes it suitable for smaller devices.

[0050] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
