Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic clocks with seconds display, in particular to an electronic clock with seconds display. Background Art
[0002] The traditional pointer-type electronic clocks hung on the wall are usually used to tell time at home. They are powered by No. 5 dry batteries with an output voltage of 1.5V. However, traditional electronic clocks do not have a module that can display the battery power, and ordinary dry batteries cannot be charged and are not durable. Sometimes when the battery runs out, the clock hands will stop moving. If the clock can display the battery power, we can clearly know the battery usage and facilitate battery replacement.
[0003] An electronic clock with a dynamic second display, publication number CN204965018U, includes a control circuit board, a human body sensor, a clock dial, and a ring-shaped dot matrix composed of a plurality of light-emitting point units. 60 second scales are arranged on the clock dial, and each second scale corresponds to at least one light-emitting point unit. The human body sensor is connected to the control circuit board, and a control system is arranged in the control circuit board, which can sequentially activate the light-emitting point units corresponding to the 60 second scales.
[0004] In order to ensure a better display effect, electronic clocks currently on the market are generally added with light-emitting units so that the electronic clock can clearly observe the time even in the dark. However, the electronic clock gradually lights up a number of light-emitting units, using the lag of human vision to form a continuous running effect. This type of electronic clock will continue to work after it is turned on. If it needs to be turned off, the main power supply needs to be disconnected, that is, the time display of the electronic clock will also stop. In addition, the power consumption of the operation of the several light-emitting units is large, resulting in a significant decrease in energy saving.
[0005] Therefore, we propose an electronic clock with a seconds display. Utility Model Content
[0006] The purpose of the utility model is to provide an electronic clock with a seconds display to solve the problems raised in the above background technology.

[0008] A support rod is plugged into the bottom of the conductor, a return spring is fixed to the top of the support rod, the top of the return spring is fixed inside the conductor, a ball is rotated on the bottom of the support rod through a pin, and a light-emitting lamp is fixed on the top of the conductor.

[0012] Preferably, the conductive sheet is connected to the control circuit board via a wire, and the conductive sheet corresponds to the light-emitting unit one by one.
[0013] Preferably, the ball bearings and the conductive sheet are adapted to each other, and the ball bearings, the light emitting lamp and the control circuit board are connected in series to the circuit.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] The utility model has reasonable structural design. The light brightness of the environment where the dial is located can be detected in real time through the photosensitive sensor, so that the clock is prevented from being in a lighting state in the daylight state. Only when the photosensitive sensor detects that the light illumination is less than the standard threshold value, it indicates that the clock is in a dark state. At this time, the control circuit board controls the annular luminous dot matrix to start working. In this way, as the second hand rotates, the conductor can be driven to rotate along the insulating guide line. When the conductor and the insulating guide line are in contact, the conductor is not conductive at this time, that is, the light-emitting units on the annular luminous dot matrix are not connected. When the conductor and the conductive sheet are in contact, the conductor is in a conductive state at this time, that is, the light-emitting units on the annular luminous dot matrix are connected and start to emit light. The time can be determined according to the lighting state thereof, and as the second hand continues to rotate, the light-emitting units will be lit one by one, so that the human vision can produce the effect of running bright spots through the state of continuous lighting point by point, forming an illusion of continuous lighting, while in fact only one group of light-emitting units is connected to the circuit, which greatly saves power and improves endurance.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-Figure 2 The utility model provides a technical solution: an electronic clock with a seconds display, comprising a watch case 1, a dial 2 is nested on the watch case 1, an annular luminous dot matrix 3 is arranged on the outer edge of the surface of the dial 2, a minute hand 4, an hour hand 5 and a second hand 6 are rotatably arranged in the middle of the dial 2, a conductor 9 is fixedly arranged on the end of the second hand 6, an insulating guide wire 7 corresponding to the conductor 9 is arranged on the dial 2, a conductive sheet 8 adapted to the conductor 9 is fixedly arranged on the insulating guide wire 7, and the number of the conductive sheets 8 corresponds to the annular luminous dot matrix 3, the conductive sheet 8 is arranged on the circle where the end of the second hand 6 is located, the annular luminous dot matrix 3 includes 60 light-emitting units, and the light-emitting units are arranged as LED lamp beads, and the light-emitting units correspond to the second hand 6, the watch case 1 has a built-in control circuit board electrically connected to the annular luminous dot matrix 3, the dial 2 has a built-in photosensitive sensor, and they are respectively arranged inside the watch case 1 and integratedly installed on the control circuit board.
[0021] In actual use, since a photosensitive sensor is provided, the light brightness of the environment in which the dial 2 is located can be detected in real time through the photosensitive sensor, so as to prevent the clock from being still in the lighting state in the daylight state. Only when the photosensitive sensor detects that the light illumination is less than the standard threshold value, it indicates that the clock is in the dark state. At this time, the control circuit board controls the annular luminous dot matrix 3 to start working, so that with the rotation of the second hand 6, the conductor 9 can be driven to rotate along the insulating guide wire 7. When the conductor 9 and the insulating guide wire 7 are in contact, the conductor 9 is not conductive, that is, the light-emitting unit on the annular luminous dot matrix 3 is not connected. When the conductor 9 and the conductive sheet 8 are in contact, the conductor 9 is in a conductive state, that is, the light-emitting unit on the annular luminous dot matrix 3 is connected and starts to emit light. The time can be determined according to its lighting state, and as the second hand 6 continues to rotate, the light-emitting units will be lit one by one. In this way, the state of continuous lighting point by point can make the human vision produce the effect of running bright spots, forming an illusion of continuous lighting, while in fact only one group of light-emitting units is connected to the circuit, which greatly saves power and improves endurance.
[0022] A power display meter 14 is fixedly mounted on the dial 2, and a power supply device is fixed inside the watch case 1. The power supply device is connected to the voltage-reducing device and the power display meter 14 via wires, and the voltage-reducing device is connected to the control circuit board via wires. The power supply device can provide power for the watch, and after the voltage-reducing effect of the voltage-reducing device, the power display meter 14 displays the remaining power of the watch in real time, so that the battery power usage can be reflected in real time after power is turned on.
[0023] See also Figure 2, the bottom of the conductor 9 is plugged with a support rod 10, the top of the support rod 10 is fixed with a reset spring 11, the top of the reset spring 11 is fixed inside the conductor 9, the bottom of the support rod 10 is rotated by a pin and equipped with a ball 12, the top of the conductor 9 is fixed with a light-emitting lamp 13, the conductive sheet 8 is connected to the control circuit board through a wire, the conductive sheet 8 and the light-emitting unit correspond one to one, the ball 12 and the conductive sheet 8 are adapted, and the ball 12, the light-emitting lamp 13 and the control circuit board are connected in series to the circuit. In actual use, the second hand 6 drives the conductor 9 to move, and the ball 12 moves along the insulating guide wire 7. When the ball 12 contacts the conductive sheet 8, the conductive sheet 8 can prompt the ball 12 to return to the support rod 10. The reset spring 11 is squeezed to compress the reset spring 11, which can provide the ball 12 with an extrusion force on the conductive sheet 8 to prevent the luminous failure caused by poor contact. At the same time, the reset spring 11 can give the ball 12 and the dial 2 a contact force to improve the stability of the second hand 6 during rotation. When the second hand 6 rotates, the ball 12 is rolled and assembled on the dial 2, so the rotation resistance of the second hand 6 is small. When the conductor 9 and the insulating guide wire 7 are in contact, the conductor 9 is not conductive at this time, that is, the light-emitting unit on the annular light-emitting dot matrix 3 is not connected. When the conductor 9 and the conductive sheet 8 are in contact, the conductor 9 is in a conductive state, that is, the light-emitting unit on the annular light-emitting dot matrix 3 is connected and starts to emit light.
[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
