[0002] In the television industry, screwless back cover mounting is gradually becoming a popular trend. This design, with its clean lines and seamless aesthetics, has gained favor with many manufacturers and consumers.

[0003] The current mainstream solution for fixing the back cover of a TV without screws is to first install clips on the back panel and then use the clips to fix the back cover to the back panel. However, in related technologies, the clips still need to be installed on the back panel with screws, which makes it inconvenient to install and remove the clips and affects subsequent maintenance. Utility Model Content

[0004] Therefore, it is necessary to provide a home appliance that addresses the issue of improving the material convenience of fasteners.

[0005] This application provides a household appliance, including:

[0006] case;

[0007] The back plate has interconnected mounting holes and clearance holes;

[0008] The fastener includes:

[0009] A snap-fit ​​body, which is used to connect with the housing;

[0010] The mounting post is connected to the buckle body, the mounting post is inserted into the mounting hole, and the side wall of the mounting post is provided with a locking part.

[0011] The latching member can switch between a locked position and an unlocked position relative to the back plate. In the unlocked position, the latching part is aligned with the clearance hole and can pass through the clearance hole so that the mounting post can be inserted into or removed from the mounting hole. In the locked position, the latching part is misaligned with the clearance hole, and the latching part abuts against the side of the back plate away from the latching body.

[0012] The technical solution will be further explained below:

[0013] In one embodiment, one of the buckle body and the back plate is provided with a positioning post protruding out, and the other is provided with a positioning hole. When in the locked position, the positioning post is inserted into the positioning hole.

[0014] In one embodiment, the buckle body has a protruding anti-loosening protrusion that abuts against the side of the back plate near the buckle body.

[0015] In one embodiment, the latching portion has a first abutting surface for abutting against the back plate, and the anti-loosening protrusion has a second abutting surface for abutting against the back plate, wherein the vertical distance between the first abutting surface and the second abutting surface is less than or equal to the thickness of the back plate.

[0016] In one embodiment, there are multiple anti-loosening protrusions, which are spaced apart on the side of the buckle body near the back plate.

[0017] In one embodiment, the back plate has a boss protruding toward the side close to the buckle body, the mounting hole and the clearance hole are both formed on the boss, and a groove is formed on the side of the boss away from the buckle body, the groove being in communication with the mounting hole and the clearance hole.

[0018] In one embodiment, the latching part has a conical structure, and the radius of the latching part gradually decreases along the direction away from the buckle body from the mounting post; the clearance hole is semi-circular or fan-shaped, and the diameter of the clearance hole is larger than the maximum diameter of the latching part.

[0019] In one embodiment, the housing has a protruding snap-fit ​​portion on the side near the back plate, which engages with the buckle body.

[0020] In one embodiment, the buckle body includes two hook portions, which are arranged opposite to each other. A groove for accommodating the snap-fit ​​portion is formed between the two hook portions, and the two hook portions are respectively snapped into the opposite sides of the snap-fit ​​portion.

[0021] In one embodiment, there are multiple fasteners, which are spaced apart along the edge of the back plate.

[0022] During assembly of the aforementioned home appliance, first align the locking part of the fastener with the clearance hole on the back panel. Then, insert the mounting post of the fastener into the mounting hole, ensuring the locking part passes through the clearance hole. Next, rotate the fastener to the locked position, causing the locking part to misalign with the clearance hole and abut against the side of the back panel away from the fastener body. At this point, the mounting post is confined within the mounting hole by the locking part and cannot disengage, thus achieving screwless fastening of the fastener to the back panel. Finally, connect the housing to the fastener body of the fastener, thus mounting the housing onto the back panel. When it is necessary to remove the fastener, simply switch it to the unlocked position, aligning the locking part with the clearance hole. The locking part will then release the restriction on the mounting post. Finally, pull the mounting post out of the mounting hole to separate the fastener from the back panel. Compared to traditional home appliances that require screws to fix the fasteners, the home appliance of this application can install the fasteners onto the back panel without screws, making the fasteners easier to install and remove. Furthermore, it eliminates the need to drill screw holes in the fasteners, ensuring the structural strength and overall appearance of the fasteners. Attached Figure Description

[0040] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0041] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and 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 of this application.

[0042] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0044] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0045] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, 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 possible implementation.

[0046] As described in the background section, current flat-panel TVs typically use screws to attach clips to the back panel before securing the back cover to the TV's back panel, thus avoiding exposed screws and maintaining a clean and unified appearance. However, the clips still require screws to be tightened, which is cumbersome and necessitates drilling screw holes in them. This compromises both the structural strength and the clean, unified appearance of the clips.

[0047] Based on this, one embodiment of this application provides a home appliance, which may be a flat-screen TV or other home appliances, such as a computer, refrigerator, air conditioner, washing machine, etc., without limitation.

[0048] Specifically, see Figures 1 to 5 One embodiment of the home appliance includes a housing 20, a back panel 10, and a fastener 30. The back panel 10 is used to mount electronic components. The housing 20 is fixed to the back panel 10 by the fastener 30, and the housing 20 is used to protect the electronic components on the back panel 10.

[0049] Specifically, taking a flat-panel TV as an example, the back panel 10 is located on the back of the display panel of the flat-panel TV, serving to support the display panel. The back panel 10 is equipped with circuit boards, driver boards, and other electronic components, which provide electrical and control signals for the image display of the display panel. The housing 20 is the back cover of the flat-panel TV, and the back cover is set on the back panel 10 by the fasteners 30. The back cover provides protection and shielding for the back panel 10 and the circuit boards, driver boards, and other electronic components set on the back panel 10.

[0050] Referring to 11, in some embodiments, the back plate 10 has a communicating mounting hole 11 and a clearance hole 12. The mounting hole 11 is used to install the fastener 30.

[0051] Specifically, in combination Figure 12 In some embodiments, the latching member 30 includes a latching body 31 for connecting to the housing 20.

[0052] See also Figure 12In some embodiments, the buckle 30 further includes a mounting post 321, which is connected to the buckle body 31. The mounting post 321 is inserted into the mounting hole 11, and a locking part 322 protrudes from the side wall of the mounting post 321.

[0053] Furthermore, combined Figures 6 to 10 The latching member 30 has a locked position and an unlocked position. The latching member 30 can switch between the locked position and the unlocked position relative to the back plate 10. For example, the latching member 30 can rotate relative to the back plate 10 to switch between the locked position and the unlocked position. Specifically, see Figure 9 In the unlocked position, the latch 322 aligns with and can pass through the clearance hole 12, allowing the mounting post 321 to be inserted into or removed from the mounting hole 11; combined with Figure 10 When in the locked position, the latching part 322 is misaligned with the clearance hole 12, and the latching part 322 abuts against the side of the back plate 10 away from the buckle body 31.

[0054] For example, during the assembly of the aforementioned home appliance, the locking part 322 of the fastener 30 is first aligned with the clearance hole 12 on the back plate 10. Then, the mounting post 321 of the fastener 30 is inserted into the mounting hole 11, and the locking part 322 passes through the clearance hole 12. Subsequently, the fastener 30 is rotated to the locked position, so that the locking part 322 is misaligned with the clearance hole 12 and abuts against the side of the back plate 10 away from the fastener body 31. At this time, the mounting post 321 is limited in the mounting hole 11 by the locking part 322 and cannot come out of the mounting hole 11, thus achieving screwless fixing of the fastener 30 to the back plate 10. Finally, the housing 20 is connected to the fastener body 31 of the fastener 30, thus achieving the installation of the housing 20 on the back plate 10. When it is necessary to remove the buckle 30, simply rotate the buckle 30 to the unlock position so that the locking part 322 is aligned with the clearance hole 12. At this time, the locking part 322 can release the restriction on the mounting post 321. Then, pull the mounting post 321 out of the mounting hole 11 to separate the buckle 30 from the back plate 10.

[0055] Compared to traditional home appliances that require screws to fix the fasteners, the home appliance of this application can install the fastener 30 onto the back panel 10 without screws, and the fastener 30 can be locked and removed by rotating it, making the fastener 30 easier to install and remove. Furthermore, there is no need to drill screw holes on the fastener 30, which ensures the structural strength and overall appearance of the fastener 30.

[0056] For example, in some embodiments, the locking position and unlocking position of the latching member 30 differ by a predetermined angle along the circumferential direction of the mounting hole 11. Optionally, the predetermined angle can be selected from 30° to 180°, such as 30°, 60°, 90°, 120°, 145°, or 180°, etc., without limitation. Thus, after inserting the latching member 30 into the mounting hole 11 in the unlocked position, rotating the latching member 30 through the predetermined angle will rotate the latching member 30 to the locking position, thereby fixing the latching member 30 on the back plate 10, which is convenient to operate.

[0057] See Figure 10 In some embodiments, the buckle body 31 also has a protruding positioning post 33, and the back plate 10 has a positioning hole 13. When in the locked position, the positioning post 33 is inserted into the positioning hole 13. Thus, on the one hand, when the buckle 30 rotates from the unlocked position to the locked position, the positioning post 33 falls into the positioning hole 13, providing positive feedback to the operator, reminding them that the buckle 30 has been rotated into place. On the other hand, the cooperation between the positioning post 33 and the positioning hole 13 locks the buckle 30 in the locked position, preventing it from rotating arbitrarily and disengaging from the mounting hole 11, thereby improving the connection stability between the buckle 30 and the back plate 10. It is easy to understand that when it is necessary to remove the buckle 30, simply pull the positioning post 33 out of the positioning hole 13 to release the lock on the buckle 30, and then rotate the buckle 30 to the unlocked position to remove it.

[0058] Alternatively, in some other embodiments, the positioning post 33 may also be provided on the back plate 10, and correspondingly, the positioning hole 13 is provided on the buckle body 31, so as to achieve positioning of the buckle body 31, which will not be described in detail here.

[0059] Optionally, in some embodiments, the number of positioning pins 33 and positioning holes 13 can be one or more, as long as it is ensured that the positioning pins 33 can be inserted into the positioning holes 13 one by one in the locked position, and there is no limitation here.

[0060] See Figure 12 In some embodiments, optionally, the buckle body 31 is provided with an anti-loosening protrusion 34, which abuts against the side of the back plate 10 near the buckle body 31. Specifically, when the buckle 30 is rotated to the locked position, the anti-loosening protrusion 34 and the locking part 322 can abut against the opposite sides of the back plate 10 respectively. In this way, by cooperating with the anti-loosening protrusion 34 and the locking part, the back plate 10 can be clamped from the opposite sides, improving the connection stability between the buckle 30 and the back plate 10 and preventing the buckle 30 from loosening.

[0061] Optionally, in some embodiments, the locking portion 322 has a first abutting surface for abutting against the back plate 10, and the anti-loosening protrusion 34 has a second abutting surface for abutting against the back plate 10. The vertical distance between the first abutting surface and the second abutting surface is less than or equal to the thickness of the back plate 10. Understandably, the anti-loosening protrusion 34, the locking portion 322, and the back plate 10 all have a certain elastic deformation capability. By configuring the distance between the anti-loosening protrusion 34 and the locking portion 322 to be less than or equal to the thickness of the back plate 10, it is ensured that the anti-loosening protrusion 34, the locking portion 322, and the back plate 10 can form an interference fit, thereby further improving the connection stability between the fastener 30 and the back plate 10.

[0062] Optionally, in some embodiments, the number of anti-loosening protrusions 34 is multiple, such as two, three, four, five or more, and the multiple anti-loosening protrusions 34 are spaced apart on the side of the buckle body 31 near the back plate 10. By having multiple anti-loosening protrusions 34 abut against the back plate 10 together, the contact area between the anti-loosening protrusions 34 and the back plate 10 can be increased. This improves the connection stability between the anti-loosening protrusions 34 and the back plate 10, while avoiding stress concentration between the back plate 10 and the anti-loosening protrusions 34, making the force on the back plate 10 more uniform, and further improving the connection stability between the back plate 10 and the buckle 30.

[0063] See Figure 9 as well as Figure 10 Optionally, in one embodiment, the back plate 10 has a boss portion 14 protruding toward the side near the buckle body 31, and both the mounting hole 11 and the clearance hole 12 are formed on the boss portion 14. A groove 15 is formed on the side of the boss portion 14 away from the buckle body 31, and the groove 15 communicates with the mounting hole 11 and the clearance hole 12.

[0064] It is easy to understand that the boss portion 14 can raise the latching member 30, ensuring a stable connection between the latching member 30 and the housing 20. Furthermore, the boss portion 14 can strengthen the structural strength at the connection between the back plate 10 and the latching member 30, improving the stability of the connection between the latching member 30 and the back plate 10. In addition, by forming a groove 15 on the side of the boss portion 14 away from the latching body 31, the groove 15 can accommodate the mounting post 321, preventing interference between the mounting post 321 and other components of the back plate 10 on the side away from the latching body 31 (such as the backlight module of a flat-panel TV, the display panel, etc.).

[0065] Specifically, in some embodiments, the back plate 10 can be a sheet metal part, and the boss 14 and the groove 15 can be formed on the back plate 10 in one stamping process, thereby simplifying the forming process.

[0066] Optionally, the boss portion 14 can be a rectangular boss, a circular boss, or other irregularly shaped boss, and there is no limitation on this.

[0067] See Figure 12In some embodiments, the locking portion 322 has a conical structure, such as a semi-circular cone or a fan-shaped cone, and the radius of the locking portion 322 gradually decreases along the direction away from the latching body 31 from the mounting post 321. Correspondingly, the clearance hole 12 is semi-circular or fan-shaped, and the diameter of the clearance hole 12 is larger than the maximum diameter of the locking portion 322. By configuring the diameter of the clearance hole 12 to be larger than the maximum diameter of the locking portion 322, it is ensured that the locking portion 322 can pass smoothly through the clearance hole 12 when the latching member 30 is in the unlocked position. Furthermore, by configuring the locking portion 322 as a semi-circular cone structure that is larger at the top and smaller at the bottom, it is easier for the locking portion 322 to penetrate into the clearance hole 12.

[0068] For example, the central angle corresponding to the semi-conical structure of the locking part 322 can be 30° to 270°, such as 30°, 90°, 180° or 270°, so as to ensure the structural strength of the locking part 322 itself, while ensuring that the locking part 322 and the back plate 10 have sufficient contact area, thereby improving the connection strength between the fastener 30 and the back plate 10.

[0069] Understandably, in other embodiments, the locking part 322 may also be a cylindrical structure, a prism structure, or a hook structure, etc., and there is no limitation here.

[0070] See Figure 5 In some embodiments, a snap-fit ​​portion 21 protrudes from the side of the housing 20 near the back plate 10, and the snap-fit ​​portion 21 engages with the snap-fit ​​body 31. By engaging the snap-fit ​​portion 21 with the snap-fit ​​body 31, the housing 20 is installed and fixed onto the back plate 10, improving the ease of installation of the housing 20.

[0071] In conjunction with 8, in some embodiments, the buckle body 31 includes two hook portions 311, which are disposed opposite to each other. A groove 312 for accommodating the engaging portion 21 is formed between the two hook portions 311, and the two hook portions 311 are respectively engaged with the opposite sides of the engaging portion 21. Exemplarily, hook structures are provided on both sides of the hook portions 311. By engaging the two hook portions 311 with the hook structures on the opposite sides of the engaging portion 21, the connection stability between the buckle body 31 and the hook portions 311 is improved, thereby improving the stability of the housing 20.

[0072] For example, in some embodiments, the slot 312 is a U-shaped slot, which makes it easier for the snap-fit ​​portion 21 to be inserted into the slot 312, thereby improving the ease of installation of the housing 20.

[0073] Optionally, in some embodiments, the number of fasteners 30 is multiple, such as two, three, four, five, six, or more, and the multiple fasteners 30 are spaced apart along the edge of the back plate 10. Correspondingly, the housing 20 is provided with multiple engaging portions 21 on the side near the back plate 10, and each engaging portion 21 engages with each fastener 30, thereby improving the connection stability between the housing 20 and the back plate 10.

[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0075] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
