Description

[Technical Field]

[0001] This utility model relates to the field of clock technology, specifically to a clock that can display seconds by emitting light from the back. [Background Technology]

[0002] Clocks are ubiquitous in households, serving to help people tell time. A clock mainly consists of a dial, a digital display, and a back cover. Ordinary clocks lack illumination and cannot display the time at night. To meet the need for nighttime timekeeping, luminous clocks were gradually developed. There are many ways luminous clocks emit light, such as coating the dial with fluorescent agents or installing LED strips inside the dial. To ensure clear reading of minutes and seconds, some even incorporate multiple light-emitting devices on the dial, not only illuminating the dial but also clearly displaying the seconds.

[0003] For example, CN2566310Y discloses a second-indicating electronic clock with a digital display in the center of the dial and 60 light-emitting elements evenly distributed around the perimeter. This clock has a simple and elegant design and good night-vision performance. However, because the 60 light-emitting elements are mounted on the dial surface, the light shines directly into people's eyes at night, resulting in excessive brightness and making it unsuitable for visual viewing; this has led to a poor market response.

[0004] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. [Utility Model Content]

[0005] This invention aims to solve the technical problem that the light of existing luminous clocks is too glaring and unsuitable for visual viewing. It provides a clock that can emit light from the back to display the seconds. The 60 light-emitting elements simulate 60 second marks and are projected onto the wall behind the clock, so that people can clearly see the time at night without glare.

[0006] This invention is implemented as follows: a clock that can emit light from the back to display the number of seconds includes an electronic board and a back cover, wherein 60 light-emitting elements are evenly distributed around the periphery of the side of the electronic board facing the back cover.

[0007] Furthermore, the 60 light-emitting elements are arranged in a circular, equidistant pattern.

[0008] Furthermore, the back cover has 60 light-reflecting grooves, and the 60 light-reflecting grooves are distributed in a one-to-one correspondence with 60 light-emitting elements.

[0009] Furthermore, the light reflector includes an inclined sidewall, a light inlet is formed on the side of the inclined sidewall facing the light-emitting element, a top wall is fixed on the side of the inclined sidewall opposite the inlet, and a light outlet is formed on the opposite side of the inclined sidewall.

[0010] Furthermore, a partition is provided between adjacent light reflector slots.

[0011] Furthermore, the light-emitting element is an LED lamp.

[0012] Furthermore, a battery mounting boss is formed in the middle of the rear cover; a plurality of outwardly extending extension plates are formed on the outer periphery of the battery mounting boss, and a winding space is formed between the extension plates and the rear cover.

[0013] Furthermore, the multiple extension plates are arranged at equal intervals.

[0014] Furthermore, it also includes a dial mounted on the side of the electronic board opposite the back cover.

[0015] The advantages of this utility model are:

[0016] 1. By placing the light-emitting elements on the side of the electronic board facing the back cover, the light emitted by the light-emitting elements forms luminous second dots on the wall. The luminous second dots are projected onto the wall instead of shining directly into the eyes. The 60 light-emitting elements are evenly distributed along the perimeter of the electronic board, so that the 60 luminous second dots are distributed in a regular circle to simulate the second scale of a clock.

[0017] 2. Sixty light-emitting elements simulate 60 illuminated second dots projected onto the wall behind the clock. This illuminates the clock at night while allowing people to clearly see the time. The light is not direct into the eyes, making it comfortable to see. An electronic board controls the 60 light-emitting elements to light up sequentially from 1 to 60, thus projecting illuminating second dots onto the wall from 1 to 60. Once all 60 are lit, they are all turned off, and the cycle repeats.

[0018] 3. By setting a light reflector on the back cover, the light first shines into the light reflector and then reflects out, making the diameter of the light circle formed by the light-emitting second point larger and spreading outward, so that people can see the time more clearly.

Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0027] Please see Figures 1 to 4 As shown, a clock capable of displaying seconds by emitting light from the back includes an electronic board 1 and a back cover 2. Sixty light-emitting elements 3 are evenly distributed around the periphery of the side of the electronic board 1 facing the back cover 2. The electronic board 1 can control the light-emitting elements 3 to emit light cyclically.

[0028] The clock with a backlight that can display seconds has at least the following beneficial technical effects:

[0029] 1. By installing the light-emitting element 3 on the side of the electronic board 1 facing the back cover 2, the light emitted by the light-emitting element 3 forms a light-emitting second point on the wall. The light-emitting second point is projected on the wall instead of shining directly into the eyes. 60 light-emitting elements 3 are evenly distributed along the periphery of the electronic board 1, so that the 60 light-emitting second points are distributed in a regular circle, which is used to simulate the second scale of a clock.

[0030] 2. Sixty light-emitting elements 3 simulate 60 luminous second dots projected onto the wall behind the clock. This illuminates the clock at night, allowing people to clearly see the time without the light shining directly into their eyes, making it suitable for visual viewing. Electronic board 1 controls the 60 light-emitting elements 3 to light up sequentially from 1 to 60, thus projecting luminous second dots onto the wall from 1 to 60. Once all 60 are lit, they are all turned off, and the cycle repeats.

[0031] In this invention, the 60 light-emitting elements 3 are arranged in a circular, equidistant pattern to simulate the second-count distribution of a clock, making the projected light-emitting second points more regular and aesthetically pleasing.

[0032] In this invention, the back cover 2 has 60 light-reflecting grooves 4, and the 60 light-emitting elements 3 are distributed one-to-one. To prevent the light from being blocked by the back of the clock when projected vertically onto the wall, the light-reflecting grooves 4 are provided on the back cover 2. The light first enters the light-reflecting grooves 4 and then is reflected outward, making the diameter of the aperture formed by the multiple light-emitting seconds larger and spreading outward, so that people can see the time more clearly.

[0033] In this invention, the light reflector groove 4 is formed on the side of the back cover 2 away from the electronic board 1. The 60 light reflector grooves 4 are arranged in a regular circular pattern, so that the 60 light reflector grooves 4 can correspond one-to-one with the 60 light-emitting elements 3.

[0034] In this utility model, reference is made to the appendix. Figure 4 As shown, the light reflector 4 includes an inclined sidewall 41. A light inlet 42 is formed on the side of the inclined sidewall 41 facing the light-emitting element 3. A top wall 43 is fixed on the side of the inclined sidewall 41 opposite the inlet. A light outlet 44 is formed opposite the inclined sidewall 41. Part of the light emitted by the light-emitting element 3 is directed towards the inclined sidewall 41, then reflected to the top wall 43, and then emitted from the light outlet 44, finally projecting onto the wall to form a light-emitting dot.

[0035] In this invention, a partition 45 is provided between adjacent light reflector troughs 4. The light emitted by any light-emitting element 3 can only be reflected in the corresponding light reflector trough 4. After the light-emitting seconds are projected onto the wall, there is a gap between adjacent light-emitting seconds, which can prevent the overlapping of adjacent light-emitting seconds and make it easier for people to read the accurate time.

[0036] In this invention, the light-emitting element 3 is an LED lamp. LED lamps have the advantages of energy saving, environmental protection, long lifespan, and small size.

[0037] In this invention, a boss 5 is formed in the middle of the rear cover 2; the boss 5 is formed on the side of the rear cover 2 away from the electronic board 1. Multiple outwardly extending extension plates 6 are formed around the outer periphery of the boss 5, and a winding space is formed between the extension plates 6 and the rear cover 2. Wires can be wound around the outside of the boss 5, avoiding redundant exposed wires that would affect aesthetics. A battery mounting cavity is provided inside the boss 5.

[0038] This invention also includes a dial 7 mounted on the side of the electronic board 1 opposite the back cover 2; the dial 7, the electronic board 1, and the back cover 2 are assembled sequentially from front to back. The dial 7 can display information such as year, month, day, hour, and minute.

[0039] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
