Abstract
The utility model discloses a stop watch power supply system comprising a stop watch and a stop watch circuit arranged in the stop watch, wherein the stop watch circuit is respectively provided with a first button and a second button; a bottom of the stop watch is externally connected with a first cell box and a second cell box, the first cell box and the second cell box are provided with two identical cells, and the two cells are connected in a parallel manner; the stop watch of the utility model is used for long distance cycling, and the stop watch will not be unavailable because that the cell energy is running out; when the cells are replaced, firstly one cell is replaced and then the other cell is replaced, because the circuit is always powered up by power source, so cycling data will not be erased in power failure; and the stop watch power supply system is easy in usage, and prolongs cell serving time of the stop watch.
Description
Technical field
The utility model relates to a kind of code table, specifically relates to a kind of code table electric power system.
Background technology
Since the relatively power consumption of wireless bicycle code table, the bicycle code table that has noctilucent function and GPS code table, and present code table uses the power supply power supply of 3V or 1.5V, uses a 3V battery when needing 3V, uses a 1.5V battery when needs 1.5V.During long-distance riding, often can't use because battery electric quantity exhausts out of doors, when changing battery, the data of riding can all be removed.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of two battery cases that have, and has made things convenient for use, the code table electric power system that prolongs battery service time of code table.
The utility model is achieved through the following technical solutions:
A kind of code table electric power system comprises code table, and is arranged on the code table circuit in the code table, is respectively equipped with first button and second button on the described code table circuit.
As optimized technical scheme, described code table lower end is circumscribed with first battery case and second battery case.
As optimized technical scheme, be provided with two identical batteries in described first battery case and second battery case, thereby increase the battery altering time of code table, when preventing long-distance riding code table because battery electric quantity exhausts idle phenomenon.
As optimized technical scheme, connect by parallel way between described two batteries, owing to be parallel way, when changing battery, change a battery earlier, change another battery again.
The beneficial effects of the utility model are: code table of the present utility model, when long-distance riding, code table can can't not use because battery electric quantity exhausts, when changing battery, change a battery earlier, change another battery again, because the power supply of circuit one direct power supply, the data of riding can not removed because of power down, have made things convenient for use, prolong the battery service time of code table.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the circuit block diagram of the utility model code table electric power system.
Embodiment
As shown in Figure 1, a kind of code table electric power system of the present utility model comprises code table, and is arranged on the code table circuit in the code table, is respectively equipped with first button and second button on the described code table circuit.
Wherein, described code table lower end is circumscribed with first battery case and second battery case.
Be provided with two identical batteries in described first battery case and second battery case, thereby increase the battery altering time of code table, when preventing long-distance riding code table because battery electric quantity exhausts idle phenomenon.
Connect by parallel way between described two batteries, owing to be parallel way, when changing battery, change a battery earlier, change another battery again.
Two battery cases of design below the table body of code table, put into two identical batteries in two battery cases simultaneously, the connected mode of two batteries is in parallel, they are with advancing all to give circuit supply, when changing battery, change a battery earlier, change another battery again, because the power supply of circuit one direct power supply, the data of riding can not removed because of power down.
The beneficial effects of the utility model are: code table of the present utility model, be provided with two battery cases after, made things convenient for use, prolonged code table the service time of battery, better guaranteed the normal use of code table in the long-distance process of riding.
The above only is embodiment of the present utility model, but protection range of the present utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
