Abstract
The utility model relates to a wireless water-proof stopwatch which comprises an instrument head and a wireless sensor. The technique key point is in that, a LCD display mask (2) is placed on a facing cap of the instrument (1), a liquid crystal screen LCD is mounted in the LCD display mask (2) and is connected with a wiring board through a bus bar. The wiring board comprises a chip, an element and a wireless receiving modular. The electric signal of a senor sending modular is received and transported to the receiving modular by the wiring board, and the chip on the wiring board makes a signal treatment and reflects the result to the liquid crystal screen LCD to display the data of the wireless movement. The wireless water-proof stopwatch, which employs the advanced wireless electronic technique, solves the evil that the connection between the instrument head of the general stopwatch and the sensor by electric wire has complex installment, potential safety hazard and bad displaying accuracy.
Description
One, technical field:
The utility model relates to body-building, and the leisure instrument is specially adapted to be installed on bicycle, above the sport car etc., as a kind of wireless waterproof code table of counting speed.
Two, background technology:
At present, domestic general code table is all finished sensor with connecting line and is connected with the signal of instrument, mainly has following shortcoming:
(1) trouble is installed: Dial of instrument adopts electric wire to be connected with sensor, and fixes and fix with screw and make troubles to installation with the screwdriver that the screw model differs, the user need be equipped with all size first.
(2) potential safety hazard: adopt electric wire to connect, wire rod greatly then may cause personal safety as being sandwiched on the wheel steel wire, then can damage instrument for a short time.(3) can not waterproof: nearly all code table production commercial city solve the function of waterproof, run into bad weather situation such as rainy day gas, even have run into dew weather and all may make gauge internal make moist or intake to cause instrument normally not show.(4) demonstration is inaccurate: adopt electric wire to connect, the time has been grown, and tends to make connection terminal loosening, causes demonstration untrue, can not reflect the data of motion.
Above-mentioned some be the common fault that present code table production firm exists, thereby can not allow the user reach the effect that tests the speed normally.
Three, summary of the invention:
At above-mentioned general code table gauge outfit and sensor with electric wire be connected exist install trouble, can not waterproof, show that inaccurate shortcoming, the utility model provide a kind of Dial of instrument to be connected without electric wire with sensor, and the wireless waterproof code table of employing radiotelegraphy.
The technical scheme of the utility model is wireless waterproof code table is: it is made up of Dial of instrument and wireless senser, the instrument head comprises: instrument cover (1), LCD display frame (2), mat button (3), button (4), lower cover (5) and battery cover (6), it is characterized in that LCD display frame (2) is placed on the instrument cover (1), liquid crystal display LCD is contained in the LCD display frame (2), be connected with wiring board by bus, wiring board is by chip, outer element admittedly and wireless receiving module are formed, the wiring board group is installed in code table and moulds in the shell, and provide power supply by the 3V battery, the key of wireless portion is wireless receiving module, it is the electric signal of receiving sensor emission, goes to handle thereby offer chip.Mat button (3) is contained on the button (4), mainly plays sealing function, and battery cover (6) is contained in the middle of the lower cover (5), instrument cover (1) has all adopted ultrasonic welding process with lower cover (5), replace the trouble that the past fixedly brings with screw, and reached sealing again, the purpose of waterproof.
The electronic section of its wireless code table: electronic section has liquid crystal display LCD, electronic circuit board and related elements: (comprising chip, wireless receiving, transmitter module, compositions such as peripheral component), sensor (tongue tube), battery, compositions such as electromagnet.Specifically see Fig. 2-A for details; 2-B.Wireless waterproof code table adopts the advanced wireless power technology, solved the Dial of instrument of general code table and sensor disadvantage with the method for wireless induction with electric wire connection trouble, potential safety hazard, display precision difference, instrument cover and lower cover have adopted ultrasonic welding process, the good airproof performance cancellation past fixedly bothers and blow-by with screw, adopt the O-ring seal sealing between each space, solved the waterproof problem of instrument.
Four, description of drawings:
Fig. 1 is the product structure synoptic diagram of wireless waterproof code table.
Fig. 2-A is the schematic block circuit diagram of wireless waterproof code table Dial of instrument.
Fig. 2-B is the schematic block circuit diagram of wireless waterproof code table wireless senser.
Among the figure: 1, instrument cover; 2, LCD display frame; 3, press a button; 4, button; 5, lower cover; 6, battery cover.
Five, embodiment:
A kind of wireless waterproof code table is made up of Dial of instrument and wireless senser, LCD display frame (2) is placed on the instrument cover (1), and liquid crystal display LCD is contained in the LCD display frame (2), is connected with wiring board by bus, mat button (3) is contained in button (4), and battery cover is contained in the middle of the lower cover (5).According to Fig. 2-A, the theory of constitution figure of Dial of instrument shows: liquid crystal (LCD) is to be used for the data of display radio motion, be connected with wiring board by bus, bus is to press on the conductive gold finger that is on the wiring board, wiring board mainly is made up of chip, peripheral cell and wireless receiving module, and provides power supply by the 3V battery.The key of wireless portion is wireless receiving module, and it is the electric signal that the receiving sensor transmitter module sends, and goes to handle thereby offer chip.The theory of constitution figure of Fig. 2-B wireless senser; Wireless senser is made up of tongue tube, wireless transmitter module and power supply, its principle of work is as follows: the magnet that is installed on the wheel removes to respond to tongue tube, tongue tube is transferred to the wireless receiving module of Dial of instrument and carries out signal Processing by the chip on the wiring board after sensing signal, and the result is reflected on the LCD.
Below simply say, send signal and A received signal by B exactly, and go up the data of display radio motion, use for reference at liquid crystal (LCD).This wireless waterproof code table uses as being installed on above bicycle, the sport car etc., can measure the speed of its motion: the highest, minimum, average, instant mileage number, the distance of travelling and the parameter of multinomial motion, the sporter can be intuitively from the display screen of this code table sense data.
Claims (1)
1, a kind of wireless waterproof code table, form by Dial of instrument and wireless senser, its feature is placed on the instrument cover (1) in LCD display frame (2), liquid crystal display LCD is contained in the LCD display frame (2), be connected with wiring board by bus, mat button (3) is contained on the button (4), and battery cover (6) is contained in the middle of the lower cover (5).
