[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

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

[0034] like Figure 1-Figure 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 seat 3 and a shading cover 4, wherein a mounting cavity 11 is formed in the display box 1; the circuit board 2 is mounted in the mounting cavity 11; the display seat 3 is mounted on the circuit board 2, and the display seat 3 is provided with a mounting hole 32; the shading cover 4 is passed through the mounting hole 32 and is snap-fitted with the display seat 3.

[0035] Thereby, the difficulty of installing the light-shielding cover 4 can be reduced, which is beneficial to improving the installation efficiency, and the light-shielding cover 4 can be made less likely to be deformed or fall off, thereby improving the installation stability of the light-shielding cover 4.

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

[0037] At the same time, the side of the circuit board 2 facing the opening can be set as the installation side, and the display seat 3 can be detachably installed on the installation side of the circuit board 2. A light source component is installed on the display seat 3, and the light source component is used to irradiate light source signals, such as time signals, status signals, etc., from the opening. The display seat 3 is also provided with a mounting hole 32, which is spaced apart from the light source component, and the mounting hole 32 is configured to be arranged along the thickness direction (i.e. Figure 1 The upper and lower directions shown in the figure) penetrate the display seat 3.

[0038] The display assembly 100 further includes a light shielding sheath 4, which is made of rubber and is cylindrical in shape. The light shielding sheath 4 is matched with the mounting hole 32 so that the light shielding sheath 4 can be inserted into the mounting hole 32, and the light shielding sheath 4 can be snap-fitted with the display seat 3 to be fixed on the display seat 3. A light inlet passage is formed in the light shielding sheath 4, and a photosensitive element is provided on the circuit board 2. The photosensitive element is used to detect ambient light. The photosensitive element is arranged opposite to the light inlet passage. The light shielding sheath 4 can block the irradiation of the light source to the photosensitive element to ensure the detection accuracy of the photosensitive element.

[0039] Specifically, the circuit board 2 can be installed in the mounting cavity 11 first, and then the light shielding cover 4 can be passed through the mounting hole 32 from the end of the mounting hole 32 away from the circuit board 2 to engage with the display seat 3, and then the display seat 3 can be fixed to the circuit board 2 to complete the installation of the display assembly 100.

[0040] It can be understood that by providing a mounting hole 32 on the display base 3 and passing the light-shielding cover 4 through the mounting hole 32 to be fixed on the display base 3, unlike connecting the light-shielding cover 4 to the circuit board 2 by snaps, the difficulty of installing the light-shielding cover 4 can be reduced, and the inner peripheral wall of the mounting hole 32 can constrain the light-shielding cover 4 so that the light-shielding cover 4 is not easily deformed or falls off.

[0041] According to the display assembly 100 of the embodiment of the present invention, a mounting hole 32 is provided on the display base 3, so that the light-shielding cover 4 can be inserted into the mounting hole 32 for installation, which reduces the difficulty of installing the light-shielding cover 4 and is beneficial to improving the installation efficiency. In addition, the inner wall of the mounting hole 32 can be used to constrain the light-shielding cover 4 so that the light-shielding cover 4 is not easily deformed or falls off, thereby improving the installation stability of the light-shielding cover 4.

[0042] In some embodiments of the present invention, a clamping protrusion 43 is provided at one end of the light shielding cover 4 facing the circuit board 2, and the clamping protrusion 43 is sandwiched between the display seat 3 and the circuit board 2. Figure 1-Figure 2 As shown, a snap-in protrusion 43 may be provided at one end of the light-shielding cover 4 facing the circuit board 2, and the snap-in protrusion 43 is provided to protrude outwardly along the radial direction of the light-shielding cover 4. A snap-in plane is formed around the mounting hole 32 on the side of the display seat 3 facing the circuit board 2. When the fixed end of the light-shielding cover 4 (i.e., the end facing the circuit board 2) passes through the mounting hole 32, the snap-in protrusion 43 may stop on the snap-in plane to snap-fit ​​with the display seat 3. At this time, if the display seat 3 is mounted on the circuit board 2, the side of the snap-in protrusion 43 facing the circuit board 2 may be supported on the side wall of the circuit board 2, so that the snap-in protrusion 43 may be clamped between the display seat 3 and the circuit board 2, thereby achieving stable installation of the light-shielding cover 4.

[0043] It is understandable that by fitting the end of the shading cover 4 to the side of the circuit board 2 , it is possible to prevent the light from the light source from irradiating the photosensitive element from the gap between the shading cover 4 and the circuit board 2 , which is beneficial to improving the shading effect of the shading cover 4 .

[0044] In some embodiments of the present invention, a mounting opening with two ends open is formed in the display seat 3, a limiting flange 31 is provided in the mounting opening, at least a portion of the limiting flange 31 is spaced apart from the inner peripheral wall of the mounting opening, the limiting flange 31 defines a mounting hole 32, and the clamping protrusion 43 is clamped between the limiting flange 31 and the circuit board 2.

[0045] For example, refer to Figure 1-Figure 3As shown, a mounting opening can be formed in the display seat 3, and the mounting opening is configured to penetrate the display seat 3 in the thickness direction and be open at both ends. A limiting flange 31 is provided in the mounting opening, and the limiting flange 31 is configured to be cylindrical, one end of the limiting flange 31 is connected to the inner peripheral wall of the mounting hole 32 and the other end is extended in the direction close to the circuit board 2, and 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 in the limiting flange 31. In this way, when the light-shielding cover 4 is installed to the mounting hole 32, the limiting flange 31 can produce a slight outward deformation under the action of the light-shielding cover 4. In this way, the difficulty of installing the light-shielding cover 4 can be reduced.

[0046] In addition, the end of the limiting flange 31 facing the circuit board 2 can be formed into a clamping plane. When the light shielding cover 4 is installed, the clamping protrusion 43 can extend to the end of the limiting flange 31 facing the circuit board 2 and be clamped with the clamping plane. At this time, if the display base 3 is installed on the circuit board 2, the clamping protrusion 43 can be clamped between the limiting flange 31 and the circuit board 2. Therefore, it is helpful to simplify the structural complexity of the display assembly 100 and improve the rationality of the layout of the display assembly 100.

[0047] In some embodiments of the present invention, Figure 1-Figure 2 Through the above arrangement, the display base 3 and the circuit board 2 can limit the shading cover 4 along the circumference of the shading cover 4, thereby improving the installation stability of the shading cover 4 and the reliability of the display assembly 100.

[0048] Furthermore, the radial matching dimension of the snap-in protrusion 43 and the limiting flange 31 can be set to W, wherein 0.5mm≤W≤1.5mm. Specifically, the radial matching dimension W of the snap-in protrusion 43 and the limiting flange 31 can be set to 0.6mm; or, the radial matching dimension W of the snap-in protrusion 43 and the limiting flange 31 can be set to 1mm; or, the radial matching dimension W of the snap-in protrusion 43 and the limiting flange 31 can be set to 1.4mm, and the present invention does not impose any restrictions on this. Through the above-mentioned setting, the matching stability between the light-shielding sheath 4 and the limiting flange 31 can be ensured, and the size of the snap-in protrusion 43 can be avoided to be too large, which makes it difficult to install, thereby improving the reliability of the display assembly 100.

[0049] In some embodiments of the present invention, Figure 1 As shown, a guide surface 431 may be formed at one end of the clamping protrusion 43 facing the circuit board 2, and the guide surface 431 is configured to extend outwardly in a direction away from the circuit board 2. Through the above arrangement, when the light shielding cover 4 is installed in the mounting hole 32, the guide surface 431 may abut against the inner peripheral wall of the mounting hole 32 to achieve guidance, which can reduce the difficulty of installing the light shielding cover 4 and improve the operating feel.

[0050] Furthermore, the radial dimension of the guide surface 431 along the light shielding sheath 4 may be set to be no less than 0.5 times the radial dimension of the clamping protrusion 43. Thus, the guiding effect of the guide surface 431 may be improved.

[0051] In some embodiments of the present invention, the light-shielding cover 4 also includes a main body 41 and a light-shielding portion 42. One end of the main body 41 close to the circuit board 2 is connected to a snap-in protrusion 43 and the other end is connected to the light-shielding portion 42. The light-shielding portion 42 is constructed in a flared shape, and at least part of the light-shielding portion 42 and the main body 41 are inserted into the mounting hole 32.

[0052] For example, refer to Figure 1-Figure 3 As shown, the light shielding sheath 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 constructed in a cylindrical shape. The end of the main body 41 close to the circuit board 2 is connected with a snap-on protrusion 43, and the snap-on protrusion 43 is arranged to protrude 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 constructed in a flared shape, that is, the light shielding part 42 is constructed to gradually increase in diameter in the direction away from the circuit board 2. At least part of the light shielding part 42 and the main body 41 are both inserted into the mounting hole 32, and the inner peripheral wall of the mounting hole 32 can constrain at least part of the main body 41 and the light shielding part 42. In this way, it is possible to avoid the light shielding part 42 from flanging during transportation, thereby 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 is passed through the first hole segment 321, the second hole segment 322 is connected to the end of the first hole segment 321 facing away from the circuit board 2, the shading portion 42 is passed through the second hole segment 322, and the second hole segment 322 is constructed to have an inner diameter that gradually increases in a direction away from the circuit board 2.

[0054] For example, refer to Figure 1-Figure 3As shown, the mounting hole 32 may include a first hole section 321 and a second hole section 322. The first hole section 321 is provided at one end of the mounting hole 32 close to the circuit board 2. The first hole section 321 is matched with the main body 41, and the inner diameter of the first hole section 321 is larger than the outer diameter of the main body 41, so that the main body 41 can be arranged in intervals in the first hole section 321. The second hole section 322 is connected to the end of the first hole section 321 away from the circuit board 2. The light shielding portion 42 is arranged in the second hole section 322. The second hole section 322 is configured to gradually increase its inner diameter in the direction away from the circuit board 2, and the diameter of the second hole section 322 is larger than the outer diameter of the light shielding portion 42, so that the inner peripheral wall of the second hole section 322 can be spaced from the outer peripheral wall of the light shielding portion 42. Through the above arrangement, it is possible to avoid the inner peripheral wall of the mounting hole 32 from squeezing the light shielding cover 4 and causing the light shielding cover 4 to deform, thereby ensuring the working reliability of the light shielding cover 4 and improving the overall performance of the display assembly 100.

[0055] Furthermore, the distance between the outer wall of the light shielding cover 4 and the inner wall of the mounting hole 32 can be set to be not less than 0.5 mm. Through the above arrangement, sufficient avoidance space can be reserved for the light shielding cover 4, which is conducive to improving the reliability of the display assembly 100.

[0056] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the first hole segment 321 and the second hole segment 322 may be connected via a transition hole segment 323, and the transition hole segment 323 is configured to gradually increase in diameter in a direction away from the circuit board 2. In this way, during the installation of the light shielding cover 4, the transition hole segment 323 may guide the light shielding cover 4. Thus, the installation difficulty of the light shielding cover 4 may be reduced, the operating feel may be improved, and the overall performance of the display assembly 100 may be improved.

[0057] The present invention also provides 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 component, a display panel 200 and a display component 100 according to any of the above embodiments, the light source component is installed on the display seat 3 of the display component 100, the display component 100 is detachably installed on the display panel 200, and the light source component is arranged opposite to the display panel 200, so that the light source component can emit light source signals such as time signals, status signals, etc. through the display panel 200.

[0059] According to the panel module 1000 of the embodiment of the present invention, a mounting hole 32 is provided on the display seat 3, so that the light-shielding cover 4 can be inserted into the mounting hole 32 for installation, which reduces the difficulty of installing the light-shielding cover 4 and is beneficial to improving the installation efficiency. In addition, the inner wall of the mounting hole 32 can be used to constrain the light-shielding cover 4 so that the light-shielding cover 4 is not easily deformed or falls off, thereby improving the installation stability of the light-shielding cover 4 and improving the reliability of the panel module 1000.

[0060] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the end of the light shielding cover 4 facing away from the circuit board 2 may be protruded from the display seat 3 and pressed against the display panel 200. It is understandable that by making the end of the light shielding cover 4 fit the inner wall of the display panel 200, it is possible to prevent the light of the light source from irradiating the photosensitive element from the gap between the light shielding cover 4 and the display panel 200, which is beneficial to improving the light shielding effect of the light shielding cover 4 and improving the reliability of the panel module 1000.

[0061] The present invention further provides a household appliance.
