[0030] The following detailed description of this case is provided in conjunction with the accompanying drawings and specific embodiments.
[0031] This case involves a clock, such as Figures 1-7 As shown, it includes a housing 1 and a control panel 2 disposed within the housing 1. The housing 1 includes a main shell 11, a light guide plate 12, and a groove 13 formed between the main shell 11 and the light guide plate 12.
[0032] like Figure 3 As shown, the groove 13 has a bottom surface 131 and an inner sidewall 132 on the main shell 11, an outer sidewall 133 on the light guide plate 12, and an opening 134 located between the inner sidewall 131 and the outer sidewall 132 and opposite to the bottom surface 131.
[0033] like Figure 4 As shown, the control board 2 has an LED light source 21 located at the opening 134 and emitting light towards the bottom surface 131.
[0034] The LED light source 21 on the control board 2 plays the function of integrating a small night light or atmosphere light on the clock. The light emitted by the LED light source 21 enters the groove 13, is reflected and diffused on the bottom surface 131 and the inner side wall 132 of the groove 13, and is uniformly scattered from the outer side wall 133 formed by the light guide plate 12 after single or multiple scattering reflection, so that the originally dazzling LED point light source becomes a uniform area light source, and no obvious light spot or bright and dark stripes can be seen, and a uniform and soft light effect is obtained, bringing a comfortable user experience.
[0035] In addition, because the light is used efficiently, compared with the prior art, the LED light beads of the LED light source 21 can be arranged at a multiple distance interval to achieve the same lighting effect, that is, fewer LED light beads can uniformly illuminate a larger area, thereby bringing the technical effects of cost saving and energy saving and efficiency.
[0036] As shown in Figure 1 , Figure 2 and Figure 7 , the clock further comprises a display window 3 located on the front surface of the shell 1, the control board 2 has a front surface 201 facing the display window 3 and a back surface 202 opposite to the front surface 201; the front surface 201 has an LED array 22 corresponding to the display window 3, and the LED light source 21 is arranged on the back surface of the control board 2. The LED array 22 on the front surface 201 of the control board 2 is not specifically shown in Figure 1 and Figure 2 . The LED array 22 is arranged one by one according to the display area defined by the hollowed-out numbers or symbols of the display window 3. Further, the display window 3 comprises a transparent plate 31 and a light shielding plate 32 closely attached to the inner side of the transparent plate 31. The display area defined by the hollowed-out numbers or symbols is formed on the light shielding plate 32.
[0037] The novel clock, the LED array 22 for display and the LED light source 21 for night light atmosphere illumination are arranged on the front surface 201 and the back surface 202 of the same control board 2. Compared with the prior art, the internal structure is simplified, and the circuit connection is simple and neat, so that the material cost and the assembly cost are greatly reduced.
[0038] Of course, the clock further comprises a power supply module and related keys electrically connected to the control board 2. The power supply module can be a detachable battery or a charging interface, and the related keys can be set according to the control needs. The control board 2 is a PCB circuit board with welded LEDs, and the electrical connection and working principle of the power supply module, the related keys and the control board 2 are the prior art.
[0039] As shown in Figure 6As shown, the groove 13 is a long slot on the side of the shell 1, and the LED light source 21 is a long strip of LED light beads evenly spaced on the corresponding side of the control panel 2. The long strip of LED light beads is evenly arranged at the opening of the long slot. In this way, a long strip of ambient night light is formed on the side of the clock, which is novel and interesting.
[0040] As shown, Figure 6 the groove 13 includes a long slot 136 on the side of the shell 1 and two corner grooves 137 formed by bending and extending at both ends of the long slot 136. The light guide plate 12 has a long light emitting area 121 corresponding to the long slot 136 and two corner light emitting areas 122 corresponding to the two corner grooves 137. In this way, a long strip of ambient night light with double wings is formed on the clock, which is novel and interesting.
[0041] Further, as shown, Figure 1 the long light emitting area 121 is located on the bottom surface of the shell 1, and the two corner light emitting areas 122 are respectively located on the left and right side surfaces of the shell 1. In the normal state of the clock, the long light emitting area 121 is hidden and not visible on the front surface, and the visible light emitting area is a long strip of light emitting area formed on the bottom edge of the front surface and the light emitting double wings on the two sides. The combination of the narrow light emitting strip and the wide light emitting double wings forms a complete night light atmosphere, providing a comfortable and lively user experience.
[0042] As shown, Figure 4 the inner side wall 132 of the groove 13 is lower than the outer side wall 133, and the control panel 2 is placed on the inner side wall 132. This facilitates the compact arrangement of the control panel 2 and the display window 3 on the shell 1, and facilitates the combination of the narrow light emitting strip and the wide light emitting double wings.
[0043] As shown, Figure 5 a connecting structure is provided between the main shell 11 and the light guide plate 12. In a specific embodiment, the connecting structure is a clamping groove 123 provided on the light guide plate 12 and a clamping strip 111 provided on the main shell 11. Of course, the connecting structure can also be a clamping groove provided on the main shell 11 and a clamping strip provided on the light guide plate 12. In a specific embodiment, the clamping groove 123 and the clamping strip 111 are provided with two groups on the left and right sides. During assembly, the clamping groove 123 is aligned with the clamping strip 111 and is matched and placed, completing the mutual assembly of the main shell 11 and the light guide plate 12.
[0044] As shown, Figure 5 the light guide plate 12 has a lap joint portion 124 on the bottom surface 131 of the main shell 11. This facilitates the precise alignment and assembly of the main shell 11 and the light guide plate 12, and ensures that the connection between the main shell 11 and the light guide plate 12 is tight and there is no gap, so as to avoid the possible light leakage that may affect the overall light emitting effect.
[0045] Further, the bottom surface 131 and the overlapping portion 124 are provided with a positioning structure. Through the cooperation of the bottom surface 131 and the overlapping portion 124 and the positioning structure, the light guide plate 12 and the main shell 11 are simply and stably assembled. The positioning structure is a specific embodiment of a corresponding positioning hole and a positioning convex particle. In a specific embodiment, the bottom surface 131 is provided with a positioning convex particle 112, and the overlapping portion 124 is provided with a positioning hole 125. Because the bottom surface 131 and the light guide plate 12 are long strips, the positioning hole and the positioning convex particle can be provided with several groups along the long strip direction.
