Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to a flexible snap-fit ​​structure that facilitates disassembly and assembly. Background Technology

[0002] Many household appliances on the market have plastic casings, such as washing machines, refrigerators, and televisions. The interior of these appliances requires specific components to ensure their normal operation and use. Circuit boards, in particular, are a crucial part of these appliances, transmitting electrical signals and ensuring that the appliance executes its intended logic and functions.

[0003] Currently, there are generally two methods for securing internal components: one is to connect the internal component to the outer casing using screws, and the other is to use a snap-fit ​​structure formed by the plastic casing. For the snap-fit ​​method, existing structures are mainly directly installed on the inner wall of the casing. To secure the internal component, for components of the exact size, the casing at the snap-fit ​​connection needs to deform, creating an opening of the appropriate size so that the internal component can reach under the snap-fit ​​structure for fixation. It is evident that using this snap-fit ​​structure requires more force during installation and may damage the casing. Furthermore, if installation is incorrect and reassembly is needed, the casing at the connection point needs to be deformed further to remove the component. This is especially problematic deep inside large household appliances, where thin components like circuit boards, if perfectly matched to the dimensions of the plastic casing with no significant gap, are difficult to remove even with tools. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to propose an easily detachable elastic snap-fit ​​structure, which solves the problems of difficulty in installing and disassembling internal components of household appliances, easy damage to the casing, and difficulty in removing relatively thin components located deep inside.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A resilient snap-fit ​​structure that facilitates assembly and disassembly includes a receiving portion and at least two main bodies. The receiving portion has a receiving area for accommodating a device. The inner wall of the receiving area has at least two through holes. Partial edges of the through holes are connected to the main bodies, and each through hole corresponds to one of the main bodies. The main bodies are located within the receiving area. Each main body includes a connecting portion and an elastic portion. One end of the connecting portion is connected to the through hole, and the other end of the connecting portion extends away from the edge of the connected hole and is connected to the elastic portion. The elastic portion, the connecting portion, and the receiving portion form an integrated structure. The elastic portion is used to relatively limit and fix the device within the receiving portion. Under the action of external force, the elastic portion can tilt outward toward the through hole. When the elastic portion tilts toward the through hole, the device can be detached from the receiving portion.

[0011] Preferably, within one of the receiving portions, the number of the main bodies is two, the two main bodies are arranged opposite each other, the two main bodies are located in the middle of the side of the receiving portion, and the bottom surface of the elastic portion is on the same plane.

[0012] Preferably, the number of the main bodies in one of the receiving portions is four; the four main bodies are at the same height and arranged opposite each other in pairs.

[0013] Preferably, it further includes a fixing block located at the bottom of the interior of the receiving portion; the fixing block and the elastic portion form an installation gap for the limiting device in the vertical direction.

[0014] Furthermore, there are four fixing blocks, all of the same shape, with their upper surfaces at the same height, and the four fixing blocks are located at the four corners of the bottom of the receiving part.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish and describe features, without any order or emphasis.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The following is in conjunction with the accompanying drawings. Figures 1 to 7 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0030] Currently, most household appliances on the market use snap-fit ​​structures on their plastic casings, which are directly installed on the inner wall of the casing. To secure internal components, for components of the exact same size, the casing at the snap-fit ​​connection point needs to deform to create an opening of the appropriate size, allowing the internal component to reach under the snap-fit ​​structure and achieve its purpose of fixation. It is evident that using this snap-fit ​​structure requires more force during the installation of internal components and may damage the casing. Furthermore, if installation is incorrect or if internal components need to be inspected, removing the installed component requires further deformation of the casing at the snap-fit ​​connection point. This is especially problematic deep inside large household appliances, where thin components like circuit boards are particularly difficult to remove if they fit perfectly with the internal dimensions of the plastic casing without significant gaps.

[0031] To address this, this technical solution proposes an ergonomically designed resilient locking structure, comprising a receiving portion 1 and at least two main bodies 2. The receiving portion 1 has a receiving area 11 for accommodating devices. The inner wall of the receiving area 11 has at least two through holes 12. Part of the edge of each through hole 12 is connected to the main body 2, and each through hole 12 corresponds to one main body 2. The main body 2 is located within the receiving area 11. The main body 2 includes a connecting portion 21 and an elastic portion 22. One end of the connecting portion 21 is connected to the through hole 12, and the other end of the connecting portion 21 extends away from the edge of the hole it is connected to, and this other end is connected to the elastic portion 22. The elastic portion 22, the connecting portion 21, and the receiving portion 1 form an integrated structure. The elastic portion 22 is used to relatively limit and fix the device within the receiving portion 1. Under the action of external force, the elastic portion 22 can tilt outward toward the through hole 12. When the elastic portion 22 tilts toward the through hole 12, the device can be detached from the receiving portion 1.

[0032] When it is necessary to install internal components, because one end of the connecting part 21 is connected to the through hole 12, and the other end of the connecting part 21 extends away from the edge of the hole it is connected to, and this other end is connected to the elastic part 22, simply pressing the elastic part 22 will cause the connecting part 21 to deform accordingly. The elastic part 22 can be pushed from inside the receiving part 1 to outside the receiving part 1, and there will be no obstruction from the elastic part 22 inside the receiving part 1. Thus, the internal components can smoothly reach the required position. Then, releasing the elastic part 22 will return the elastic part 22 and the connecting part 21 to their original positions, achieving the purpose of fixing the internal components.

[0033] Similarly, when disassembly is required, simply press the elastic part 22, and the disassembly of the internal components will not be hindered, thus solving the problem of difficulty in installation and disassembly of the internal components of household appliances and easy damage to the outer casing.

[0034] Preferably, the through hole 12 is a square hole, the main body 2 is an L-shaped part, the short side plate of the L-shaped part is the connecting part 21, the long side plate of the L-shaped part is the elastic part 22, and the projection of the long side plate in the horizontal direction is located within the projection of the square hole in the horizontal direction.

[0035] Specifically, such as Figure 4As shown, the short side plate of the L-shaped component is the connecting part 21, and the long side plate of the L-shaped component is the elastic part 22. The projection of the long side plate in the horizontal direction is located within the projection of the square hole in the horizontal direction, ensuring that the elastic part 22, that is, the long side plate, can be pressed down during use to ensure that the internal components can enter and exit smoothly. In other words, the through hole 12 is larger than the elastic part 22 and will not hinder the elastic part 22 from being pressed to the outside of the receiving part 1.

[0036] Furthermore, the length of the short side plate is less than the width of the through hole, the width w1 of the short side plate is 2-3mm, and an operation clearance groove 3 is formed between the long side plate and the square hole, the width w2 of the operation clearance groove 3 is 2-3mm.

[0037] It is worth noting that the length of the short side plate is less than the width of the through hole 12, ensuring that the body 2 is smaller than the through hole 12. The body 2 can change position depending on where it connects to the through hole 12, such as... Figure 5 As shown, the width w1 of the short side plate is limited to 2-3mm. Within this range, the short side plate can meet the deformation requirements, ensuring that the elastic part 22 can be pressed outside the through hole 12 while being quickly positioned so that the user can quickly find and press it. In this embodiment, the pressing position is the elastic part 22.

[0038] An operation clearance groove 3 is formed between the long side plate and the square hole. For relatively thin devices located deep within the receiving part 1, whose dimensions perfectly match the internal dimensions of the receiving part 1, the device can be pushed out using a tool through the operation clearance groove 3. This avoids the need to pry out thin devices from inside the receiving part 1 with a tool, which could damage the receiving part 1 or prevent the device from being removed. Furthermore, when the width w2 of the operation clearance groove 3 is 2-3mm, it provides operating space for tools, facilitating mold processing, while effectively reducing the entry of external dust, thus minimizing the impact on internal devices.

[0039] Preferably, the through hole 12 is a square hole, the connecting part 21 is a vertically arranged plate structure, the length of the plate structure is less than the width of the square hole, the elastic part 22 is a right-angled trapezoidal prism, the top surface of the right-angled trapezoidal prism is connected to the bottom of the connecting part 21, the outer side surface of the plate structure, the right-angled side surface of the right-angled trapezoidal prism and the outer surface of the receiving part 1 are located in the same plane; an operation clearance groove 3 is formed between the square hole and the right-angled trapezoidal prism.

[0040] like Figure 2-3As shown, it is worth noting that the connecting part 21 is a vertically arranged plate structure, and the elastic part 22 is a right-angled trapezoidal prism. The top surface of the right-angled trapezoidal prism is connected to the bottom of the connecting part 21. That is, when installing internal components, the pressing part is the inclined side of the right-angled trapezoidal prism, which provides a larger contact area, making it easier to apply force during operation, facilitating pressing operation, ensuring uniform force distribution, reducing local stress concentration, and lowering the risk of damage.

[0041] Furthermore, the outer side of the plate structure, the right-angled side of the right-angled trapezoidal prism, and the outer surface of the receiving part 1 are located in the same plane. That is, the smooth surface of the receiving part 1 will not protrude, reducing the risk of scratching with other objects, ensuring the integrity of the connection between the main body 2 and the receiving part 1, minimizing damage, facilitating cleaning, preventing the placement of electrical appliances due to protrusion, and maintaining the neatness and aesthetics of the receiving part 1.

[0042] Preferably, the through hole 12 is a square hole, the connecting part 21 is a vertically arranged plate structure, the elastic part 22 is a sector-shaped bottom triangular prism, the included angle between the two radii of the sector of the sector-shaped bottom triangular prism is 90°, a part of the arc surface of the sector-shaped bottom triangular prism is connected to the bottom of the connecting part 21, and the projection of the remaining part of the arc surface of the sector-shaped triangular prism in the vertical direction is located within the vertical projection of the receiving part 1. The outer side of the plate structure, the right-angled side of the sector-shaped bottom triangular prism, and the outer surface of the receiving part 1 are located in the same plane; an operation clearance groove 3 is formed between the square hole and the sector-shaped bottom triangular prism.

[0043] Specifically, such as Figure 6-7 As shown, the included angle between the two radii of the sector is 90°. One radius is coplanar with the outer surface of the receiving part 1, and the other radius is perpendicular to the interior of the receiving part 1, ensuring that the required internal components can be fixed. A portion of the arc surface of the sector-shaped bottom triangular prism is connected to the bottom of the connecting part 21. The projection of the remaining portion of the arc surface of the sector-shaped triangular prism in the vertical direction is located within the vertical projection of the receiving part 1. That is, the pressing part is a raised arc. The arc-shaped pressing surface provides a natural and intuitive pressing point, which allows users to easily locate and apply force, improving the convenience of operation. Furthermore, the arc-shaped surface conforms to ergonomic principles, providing a better feel and pressing experience.

[0044] Preferably, within one of the receiving portions 1, there are two main bodies 2, which are arranged opposite to each other and located in the middle of the side of the receiving portion 1, and the bottom surfaces of the elastic portions 22 are on the same plane.

[0045] The two main bodies 2 are distributed on opposite surfaces and are positioned opposite each other. The two main bodies 2 are located in the middle of the side of the receiving part 1, which can more evenly distribute the stress on the receiving part 1, reduce local stress concentration, improve the durability and stability of the receiving part 1, and the fixing point formed by the two main bodies 2 can increase the stability of the overall structure, provide stronger fixing force, make the connection between the receiving part 1 and the internal components more secure, and reduce loosening caused by vibration or impact.

[0046] Furthermore, the bottom surface of the elastic part 22 is on the same plane, generating pressure in the same direction on the fixed device, thereby ensuring the stability and firmness of the object, uniform force distribution, and reducing damage to the fastening structure caused by force imbalance.

[0047] Preferably, within one of the receiving portions 1, there are four main bodies 2; the four main bodies 2 are at the same height and arranged opposite each other in pairs.

[0048] Specifically, the receiving part 1 is provided with four main bodies 2, which are arranged in pairs opposite each other, so as to better fix the device and keep it stable during transportation, and it is not easy for it to fall off due to uneven fixation and bumps.

[0049] Furthermore, the four main bodies 2 are located in the middle of the side of the receiving part 1, which can improve the overall aesthetics while ensuring the uniformity of force on the device.

[0050] Preferably, it further includes a fixing block 4, which is located at the bottom of the interior of the receiving portion 1; the fixing block 4 and the elastic portion 22 form an installation gap for limiting the device in the vertical direction.

[0051] Specifically, in order to securely fix the device inside the receiving part 1, the fixing block 4 is located at the bottom of the receiving part 1. When it is necessary to fix a thinner device, the fixing block 4 can play a supporting role, keeping the device stable and preventing the device from being easily damaged when fixed at the bottom of the receiving part 1. Furthermore, the fixing block 4 and the elastic part 22 form an installation gap for limiting the device. The fixing block 4 and the main body 2 work together to act on both sides of the fixed device, thereby better fixing the device.

[0052] Furthermore, there are four fixing blocks 4, all of which have the same shape and their upper surfaces are at the same height. The four fixing blocks 4 are located at the four corners of the bottom of the receiving part 1.

[0053] Specifically, the upper surfaces of the fixing blocks 4 are at the same height, and the four fixing blocks 4 are respectively located at the four corners of the bottom of the receiving part 1, so that the height of the mounting gap between the fixing blocks 4 and the elastic part 22 for the limiting device is equal. This layout helps to evenly distribute the weight of the object placed in the receiving part 1, reduce local stress concentration, and avoid deformation or damage caused by uneven weight distribution. In addition, the four fixing blocks 2 located at the four corners of the bottom of the receiving part 1 can provide better support, increase the stability of the entire structure, and reduce the occupancy of internal space.

[0054] Preferably, the length d of the elastic part 22 extending into the interior of the receiving part 1 is not greater than 5 mm, and the height h of the connecting part 21 is greater than 4 mm.

[0055] like Figure 3 As shown, when the length d of the elastic part 22 extending into the interior of the receiving part 1 is not greater than 5mm and the height h of the connecting part 21 is greater than 4mm, the elastic part 22 can be quickly pressed until there are no protrusions inside the receiving part 1 when the fixed device is removed, ensuring that the device can be smoothly removed while ensuring that the device is securely fixed.

[0056] 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.
