[0002] In related technologies, photosensitive sleeves are typically directly assembled onto circuit boards, with the sleeve and board connected via a snap-fit ​​structure. However, photosensitive sleeves are made of silicone, which has low rigidity and is difficult to assemble onto circuit boards, leading to installation difficulties and room for improvement. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, one object of the present invention is to provide a display component with a light-shielding sleeve that is easy to install, not easily deformed or detached, and has high installation stability.

[0005] According to the present invention, the display component has a mounting hole on the display base, which allows the light-shielding sleeve to be inserted through the mounting hole for installation. This reduces the installation difficulty of the light-shielding sleeve and improves installation efficiency. Furthermore, the inner peripheral wall of the mounting hole can be used to constrain the light-shielding sleeve, making it less prone to deformation or detachment, thus improving the installation stability of the light-shielding sleeve.

[0006] According to some embodiments of the present invention, in a display assembly, the light-shielding sleeve has a snap-fit ​​protrusion at one end facing the circuit board, and the snap-fit ​​protrusion is sandwiched between the display base and the circuit board.

[0008] According to some embodiments of the display component of the present invention, the snap-fit ​​protrusion is constructed in a ring shape.

[0009] According to some embodiments of the present invention, in a display assembly, the end of the snap-fit ​​protrusion facing the circuit board has a guide surface, the guide surface being configured to extend outward at an angle away from the circuit board.

[0010] According to some embodiments of the present invention, the light-shielding sleeve further includes a main body and a light-shielding part.

[0012] According to some embodiments of the present invention, the first aperture segment and the second aperture segment are connected by a transition aperture segment.

[0013] The present invention also proposes a panel module.

[0019] According to the embodiments of the present invention, the household appliance has a mounting hole on the display base, which allows the light-shielding sleeve to be inserted through the mounting hole for installation. This reduces the installation difficulty of the light-shielding sleeve, improves installation efficiency, and the inner peripheral wall of the mounting hole can be used to constrain the light-shielding sleeve, making it less prone to deformation or detachment. This improves the installation stability of the light-shielding sleeve, enhances the reliability of the panel module, and improves the overall performance of the household appliance.

[0032] Embodiments of the present invention are described in detail below. 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 the present invention, and should not be construed as limiting the present invention.

[0033] Hereinafter, a display component 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0034] like Figures 1-4As shown, the display assembly 100 according to an embodiment of the present invention includes: a display box 1, a circuit board 2, a display base 3, and a light-shielding sleeve 4. The display box 1 has a mounting cavity 11; the circuit board 2 is installed in the mounting cavity 11; the display base 3 is installed on the circuit board 2, and the display base 3 is provided with a mounting hole 32; the light-shielding sleeve 4 passes through the mounting hole 32 and is engaged with the display base 3.

[0035] This reduces the difficulty of installing the light-shielding sleeve 4, improves installation efficiency, and makes the light-shielding sleeve 4 less prone to deformation or detachment, thus improving the installation stability of the light-shielding sleeve 4.

[0036] For example, refer to Figures 1-2 As shown, the display assembly 100 includes a display box 1, a circuit board 2, and a display base 3. The display box 1 has an open mounting cavity 11. The circuit board 2 is matched and disposed with the mounting cavity 11, and the circuit board 2 can be installed into the mounting cavity 11 from the open opening. For example, a buckle can be provided on the inner peripheral wall of the mounting cavity 11, and a slot can be provided on the circuit board 2. By extending the buckle into the slot, the circuit board 2 can be snapped into the mounting cavity 11.

[0037] Simultaneously, the side of the circuit board 2 facing the open opening can be designated as the mounting side, and the display base 3 can be detachably mounted on the mounting side of the circuit board 2. A light source is mounted on the display base 3, which is used to illuminate light signals, such as time signals and status signals, from the open opening. The display base 3 also has mounting holes 32, which are spaced apart from the light source. The mounting holes 32 are constructed along the thickness direction (i.e.,...). Figure 1 (As shown in the vertical direction) runs through the display base 3.

[0038] The display assembly 100 also includes a light-shielding sleeve 4, which is made of rubber and has a cylindrical structure. The light-shielding sleeve 4 is matched with the mounting hole 32, allowing it to pass through the mounting hole 32 and to snap onto the display base 3 for fixation. A light-entry path is formed inside the light-shielding sleeve 4. A photosensitive element is provided on the circuit board 2 to detect ambient light. The photosensitive element is positioned opposite the light-entry path. The light-shielding sleeve 4 can block the light source from illuminating the photosensitive element, thus ensuring the detection accuracy of the photosensitive element.

[0039] Specifically, the circuit board 2 can be installed into the mounting cavity 11 first, and then the light-shielding sleeve 4 can be inserted from the end of the mounting hole 32 away from the circuit board 2 into the mounting hole 32 to engage with the display base 3. Then the display base 3 can be fixed onto the circuit board 2, thereby completing the installation of the display component 100.

[0040] It is understandable that by providing mounting holes 32 on the display base 3 and passing the light-shielding sleeve 4 through the mounting holes 32 to fix it on the display base 3, unlike connecting the light-shielding sleeve 4 to the circuit board 2 by a snap, the installation difficulty of the light-shielding sleeve 4 can be reduced, and the inner peripheral wall of the mounting hole 32 can constrain the light-shielding sleeve 4 so that the light-shielding sleeve 4 is not easily deformed or detached.

[0041] According to the present invention, the display component 100 has a mounting hole 32 on the display base 3, which allows the light-shielding sleeve 4 to be inserted through the mounting hole 32 for installation. This reduces the installation difficulty of the light-shielding sleeve 4 and improves the installation efficiency. Furthermore, the inner peripheral wall of the mounting hole 32 can be used to constrain the light-shielding sleeve 4, making it less prone to deformation or detachment, thus improving the installation stability of the light-shielding sleeve 4.

[0042] In some embodiments of the present invention, the end of the light-shielding sleeve 4 facing the circuit board 2 is provided with a snap-fit ​​protrusion 43, which is sandwiched between the display base 3 and the circuit board 2. For example, see reference Figures 1-2 As shown, a snap-fit ​​protrusion 43 can be provided at the end of the light-shielding sleeve 4 facing the circuit board 2. The snap-fit ​​protrusion 43 protrudes outward radially from the light-shielding sleeve 4. A snap-fit ​​surface is formed around the mounting hole 32 on the side of the display base 3 facing the circuit board 2. When the fixed end of the light-shielding sleeve 4 (i.e., the end facing the circuit board 2) passes through the mounting hole 32, the snap-fit ​​protrusion 43 can abut against the snap-fit ​​surface to snap into the display base 3. At this time, if the display base 3 is installed on the circuit board 2, the side of the snap-fit ​​protrusion 43 facing the circuit board 2 can be supported on the side wall of the circuit board 2, so that the snap-fit ​​protrusion 43 can be clamped between the display base 3 and the circuit board 2, thereby achieving stable installation of the light-shielding sleeve 4.

[0043] It is understandable that by attaching the end of the light-shielding sleeve 4 to the side of the circuit board 2, the light from the light source can be prevented from shining onto the photosensitive element through the gap between the light-shielding sleeve 4 and the circuit board 2, which helps to improve the light-shielding effect of the light-shielding sleeve 4.

[0044] In some embodiments of the present invention, the display base 3 has an open mounting port at both ends, and a limiting flange 31 is provided in the mounting port. At least a portion of the limiting flange 31 is spaced apart from the inner peripheral wall of the mounting port. The limiting flange 31 defines a mounting hole 32, and a snap-fit ​​protrusion 43 is clamped between the limiting flange 31 and the circuit board 2.

[0045] For example, refer to Figures 1-3As shown, a mounting opening can be formed within the display base 3. The mounting opening is constructed to penetrate the display base 3 along its thickness direction and is open at both ends. A limiting flange 31 is provided within the mounting opening. The limiting flange 31 is cylindrical in shape. One end of the limiting flange 31 is connected to the inner peripheral wall of the mounting hole 32, and the other end extends towards the circuit board 2. The portion of the limiting flange 31 that is not connected to the inner peripheral wall of the mounting hole 32 is spaced apart from the inner peripheral wall of the mounting hole 32, and the mounting hole 32 is defined within the limiting flange 31. Thus, when the light-shielding sleeve 4 is installed into the mounting hole 32, the limiting flange 31 can undergo a slight outward deformation under the action of the light-shielding sleeve 4. This reduces the installation difficulty of the light-shielding sleeve 4.

[0046] Alternatively, the end of the limiting flange 31 facing the circuit board 2 can be formed as a snap-fit ​​surface. After the light-shielding sleeve 4 is installed, the snap-fit ​​protrusion 43 can extend to the end of the limiting flange 31 facing the circuit board 2 and engage with the snap-fit ​​surface. At this time, if the display stand 3 is installed on the circuit board 2, the snap-fit ​​protrusion 43 can be sandwiched between the limiting flange 31 and the circuit board 2. This helps to simplify the structural complexity of the display component 100 and improves the layout rationality of the display component 100.

[0047] In some embodiments of the present invention, such as Figures 1-2 As shown, the snap-fit ​​protrusion 43 can be constructed as a ring. With the above configuration, the display base 3 and the circuit board 2 can limit the light-shielding sleeve 4 along the circumference of the light-shielding sleeve 4, thereby improving the installation stability of the light-shielding sleeve 4 and the reliability of the display assembly 100.

[0048] Furthermore, the radial fit dimension between the snap-fit ​​protrusion 43 and the limiting flange 31 can be set to W, where 0.5mm ≤ W ≤ 1.5mm. Specifically, the radial fit dimension W between the snap-fit ​​protrusion 43 and the limiting flange 31 can be 0.6mm; or, the radial fit dimension W between the snap-fit ​​protrusion 43 and the limiting flange 31 can be 1mm; or, the radial fit dimension W between the snap-fit ​​protrusion 43 and the limiting flange 31 can be 1.4mm, and the present invention does not limit this. Through the above settings, the fit stability between the light-shielding sleeve 4 and the limiting flange 31 can be guaranteed, and the difficulty in installation caused by the excessive size of the snap-fit ​​protrusion 43 can be avoided, thereby improving the reliability of the display component 100.

[0049] In some embodiments of the present invention, such as Figure 1 As shown, a guide surface 431 can be formed at the end of the snap-fit ​​protrusion 43 facing the circuit board 2. The guide surface 431 is constructed to extend outward at an angle away from the circuit board 2. With the above configuration, when the light-shielding sleeve 4 is installed into the mounting hole 32, the guide surface 431 can abut against the inner peripheral wall of the mounting hole 32 to achieve guidance, which can reduce the installation difficulty of the light-shielding sleeve 4 and improve the operating feel.

[0050] Furthermore, the radial dimension of the guide surface 431 along the light-shielding sleeve 4 can be set to be no less than 0.5 times the radial dimension of the snap-fit ​​protrusion 43. This can improve the guiding effect of the guide surface 431.

[0051] In some embodiments of the present invention, the light-shielding sleeve 4 further includes a main body 41 and a light-shielding part 42. One end of the main body 41 near the circuit board 2 is connected to a snap-fit ​​protrusion 43 and the other end is connected to the light-shielding part 42. The light-shielding part 42 is flared. At least a portion of the light-shielding part 42 and the main body 41 pass through the mounting hole 32.

[0052] For example, refer to Figures 1-3 As shown, the light-shielding sleeve 4 also includes a main body 41 and a light-shielding part 42. Both the main body 41 and the light-shielding part 42 are cylindrical. A snap-fit ​​protrusion 43 is connected to the end of the main body 41 near the circuit board 2. The snap-fit ​​protrusion 43 protrudes outward along the radial direction of the main body 41. The light-shielding part 42 is connected to the end of the main body 41 away from the circuit board 2, and the light-shielding part 42 is flared, that is, the diameter of the light-shielding part 42 gradually increases in the direction away from the circuit board 2. At least a portion of the light-shielding part 42 and the main body 41 are inserted into the mounting hole 32. The inner peripheral wall of the mounting hole 32 can constrain at least a portion of the main body 41 and the light-shielding part 42. Therefore, the light-shielding part 42 can be prevented from turning over during transportation, improving the reliability of the display assembly 100.

[0053] In some embodiments of the present invention, the mounting hole 32 includes a first hole segment 321 and a second hole segment 322. The main body 41 passes through the first hole segment 321, the second hole segment 322 is connected to the end of the first hole segment 321 away from the circuit board 2, the light-shielding part 42 passes through the second hole segment 322, and the second hole segment 322 is configured such that its inner diameter gradually increases in the direction away from the circuit board 2.

[0054] For example, refer to Figures 1-3As shown, the mounting hole 32 can be provided with a first hole segment 321 and a second hole segment 322. The first hole segment 321 is located at the end of the mounting hole 32 near the circuit board 2. The first hole segment 321 is matched with the main body 41, and the inner diameter of the first hole segment 321 is larger than the outer diameter of the main body 41, so that the main body 41 can be spaced through the first hole segment 321. The second hole segment 322 is connected to the end of the first hole segment 321 away from the circuit board 2. The light-shielding part 42 passes through the second hole segment 322. The second hole segment 322 is constructed such that the inner diameter gradually increases in the direction away from the circuit board 2, and the diameter of the second hole segment 322 is larger than the outer diameter of the light-shielding part 42, so that the inner peripheral wall of the second hole segment 322 can be spaced apart from the outer peripheral wall of the light-shielding part 42. Through the above arrangement, the inner peripheral wall of the mounting hole 32 can be prevented from squeezing the light-shielding sleeve 4, which would cause the light-shielding sleeve 4 to deform, thus ensuring the working reliability of the light-shielding sleeve 4 and improving the overall performance of the display assembly 100.

[0055] Furthermore, the distance between the outer peripheral wall of the light-shielding sleeve 4 and the inner peripheral wall of the mounting hole 32 can be set to be no less than 0.5mm. This setting allows for sufficient clearance for the light-shielding sleeve 4, which helps improve the reliability of the display assembly 100.

[0056] In some embodiments of the present invention, such as Figures 1-3 As shown, the first hole segment 321 and the second hole segment 322 can be connected by a transition hole segment 323, which is constructed such that its diameter gradually increases in the direction away from the circuit board 2. In this way, during the installation of the light-shielding sleeve 4, the transition hole segment 323 can guide the light-shielding sleeve 4. This reduces the difficulty of installing the light-shielding sleeve 4, improves the handling feel, and enhances the overall performance of the display assembly 100.

[0057] The present invention also proposes a panel module 1000.

[0058] like Figure 4 As shown, the panel module 1000 according to an embodiment of the present invention includes: a light source, a display panel 200, and a display component 100 according to any of the above embodiments. The light source is mounted on the display base 3 of the display component 100, and the display component 100 is detachably mounted on the display panel 200. The light source and the display panel 200 are arranged opposite to each other so that the light source can emit light source signals, such as time signals and status signals, through the display panel 200.

[0059] According to the present invention, the panel module 1000 has a mounting hole 32 on the display base 3, which allows the light-shielding sleeve 4 to be inserted through the mounting hole 32 for installation. This reduces the installation difficulty of the light-shielding sleeve 4 and improves the installation efficiency. Furthermore, the inner peripheral wall of the mounting hole 32 can be used to constrain the light-shielding sleeve 4, making it less prone to deformation or detachment. This improves the installation stability of the light-shielding sleeve 4 and enhances the reliability of the panel module 1000.

[0060] In some embodiments of the present invention, such as Figure 1 and Figure 4 As shown, the end of the light-shielding sleeve 4 facing away from the circuit board 2 protrudes from the display base 3 and presses against the display panel 200. It is understood that by allowing the end of the light-shielding sleeve 4 to fit against the inner wall of the display panel 200, light from the light source can be prevented from shining onto the photosensitive element through the gap between the light-shielding sleeve 4 and the display panel 200, thus improving the light-shielding effect of the light-shielding sleeve 4 and enhancing the reliability of the panel module 1000.

[0061] This invention also proposes a household appliance.

[0062] A household appliance according to an embodiment of the present invention includes a panel module 1000 according to any of the above embodiments.

[0063] According to the embodiments of the present invention, the household appliance has a mounting hole 32 on the display base 3, which allows the light-shielding sleeve 4 to be inserted through the mounting hole 32 for installation. This reduces the installation difficulty of the light-shielding sleeve 4, improves installation efficiency, and the inner peripheral wall of the mounting hole 32 can be used to constrain the light-shielding sleeve 4, making it less prone to deformation or detachment. This improves the installation stability of the light-shielding sleeve 4, enhances the reliability of the panel module 1000, and improves the overall performance of the household appliance.
