Description

Convex electronic clock

Technical Field

The utility model relates to the technical field of electronic clocks, in particular to a convex electronic clock.

Background

The convex electronic clock is a clock product, and the structure of the convex electronic clock comprises an electronic clock main body and a lug adhered to the outer side of a display part of the electronic clock, wherein the lug is formed by cutting an acrylic plate. For example, a convex body clock (single) disclosed in chinese patent, patent No. 201830193077.4. The LED display device has the advantages that the projection diverges the light of the LED lamp beads on the display part, and the display effect is enlarged through the structure, so that the display device is more beneficial to checking time.

However, the prior art has the disadvantages that: acrylic or similar plastic plates, glass plates, which are suitable for straight light guide, have poor diffusion effect.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides a convex electronic clock.

The technical scheme of the utility model is as follows:

the convex electronic clock comprises a main body, wherein bumps are adhered to the display part of the front end face of the main body and correspond to LED lamp beads, each bump comprises a frame body, a reflecting edge and a diffusion film, a rectangular groove is formed in one side, close to the main body, of the frame body, a diffusion film is attached to the inner wall, far away from the main body, of the rectangular groove, a reflecting edge is attached to the side wall, close to a notch, of the rectangular groove, and the section of each reflecting edge is in a right triangle shape and forms a 45-degree included angle with the diffusion film.

Furthermore, the frame body is made of acrylic, so that the cost is low and the processing is convenient.

Further, the reflective ribs are made of ABS, so that a hard surface can be formed, and the reflective ribs are suitable for reflecting light rays.

Further, the bottom end of the main body is adhered with a bottom plate, the distance between the front end and the rear end of the bottom plate is equal to the sum of the thickness of the main body and the thickness of the protruding block, and the rear end of the bottom plate is flush with the rear end surface of the main body. The bottom plate is used for increasing the bottom area of the electronic clock, and the convex blocks are protruded out of the front end face of the main body, so that the gravity center of the electronic clock can be inclined forwards, and the bottom plate can prevent the electronic clock from overturning.

Further, the pressure-sensitive adhesive layer is arranged on the bottom surface of the bottom plate, friction force can be greatly increased after the pressure-sensitive adhesive layer is stressed, and the possibility that the electronic clock is blown down by wind can be reduced.

The beneficial effects of the utility model are as follows: through optimizing the internal structure of lug for the light that the LED lamp pearl sent is by abundant diffusion and mainly shoots out at the preceding terminal surface of lug, does benefit to the user and looks over time.

Detailed Description

The following is a further description of embodiments of the utility model, taken in conjunction with the accompanying drawings:

as shown in fig. 1-3, the convex electronic clock comprises a main body 1, wherein a convex block 2 is adhered to a display part of the front end face of the main body 1 and corresponds to each LED lamp bead, the convex block 2 comprises a frame 5, a reflecting edge 7 and a diffusion film 8, a rectangular groove 6 is formed in one side, close to the main body 1, of the frame 5, a diffusion film 8 is adhered to the inner wall, far away from the main body 1, of the rectangular groove 6, a reflecting edge 7 is adhered to the side wall, close to a notch, of the rectangular groove 6, the cross section of the reflecting edge 7 is in a right triangle shape, and an inclined plane forms a 45-degree included angle with the diffusion film 8.

The frame body 5 is made of acrylic.

The reflective ribs 7 are made of ABS.

The bottom of the main body 1 is adhered with a bottom plate 3, the distance between the front end and the rear end of the bottom plate 3 is equal to the sum of the thickness of the main body 1 and the thickness of the protruding block 2, and the rear end of the bottom plate 3 is flush with the rear end face of the main body 1.

The bottom surface of the bottom plate 3 is provided with a pressure-sensitive adhesive layer 4.

The working principle of the utility model is as follows:

1) As shown in fig. 4, each display part of the electronic clock is provided with 7 LED beads such as abcdefg, etc., and 10 numbers such as 0-9 are displayed through the 7 LED beads, so as to display time; after the circuit board is installed, the LED lamp beads are positioned on the front end face of the main body, and then the convex blocks are adhered outside the corresponding LED lamp beads;

2) When a certain LED lamp bead is lighted, light enters the rectangular groove of the corresponding lug, and the reflection edges reflect the light at the side part of the rectangular groove to the diffusion film, so that light leakage at the side part is reduced and the brightness of the diffusion film is improved;

3) The light passes through the diffusion film and passes through the medium with different refractive indexes, so that the light is subjected to a plurality of phenomena of refraction, reflection and scattering, the light can be corrected into a uniform surface light source to achieve the effect of optical diffusion, and the light radiation area is increased.

The foregoing embodiments and description have been provided merely to illustrate the principles and best modes of carrying out the utility model, and various changes and modifications can be made therein without departing from the spirit and scope of the utility model as defined in the appended claims.
