Abstract
The utility model discloses a structure of an intelligent vehicle-mounted terminal for supplying power to a data acquisition unit. The structure of the intelligent vehicle-mounted terminal for supplying power to the data acquisition unit is characterized in that a power supply contact end for supplying voltage to peripheral equipment is arranged on the intelligent vehicle-mounted terminal; a permanent magnet for achieving positioning and pressing contact of the peripheral equipment is also arranged on the intelligent vehicle-mounted terminal; a conductive spring needle which is connected with an external power supply device and used for supplying power to the data acquisition unit is arranged on the data acquisition unit; a permanent magnet with the polarity attractive to that of the permanent magnet in the external power supply device is also arranged on the data acquisition unit; and during use, the power supplying conductive spring needle on the data acquisition unit is aligned with the power supply contact end on the intelligent vehicle-mounted terminal, and through attraction provided by the attractive magnetic poles, positioning and tight contact are achieved. Through external power supply, the data acquisition unit can be diminished, so that a magnetically attractive fixing way can be adopted, and the data acquisition unit becomes simpler in integral structure and is lighter; and the intelligent vehicle-mounted terminal can ensure continuous and stable power supply to the data acquisition unit.
Description
Technical field
The utility model relates to a kind of intelligent vehicle mounted terminal to the structure of data trap power supply.
Background technology
Traditional data trap power supply mode has two kinds: a kind of is that data trap inside carries supplying cell; Another kind is to contact by the elastic contact chip that arranges on the fixed-conductive film that arranges on the data trap and the car-mounted terminal power supply that provided by terminal is provided.Data trap need regularly charge the battery from the mode of charged pool; if battery short of electricity when collecting work is carrying out then need charging or change battery might cause data acquisition temporarily to stop, in addition; Battery disposal to service life also is a problem in a large number, is unfavorable for environmental protection.Contact the fixed sturcture that the mode that the power supply that provided by terminal is provided needs to arrange on the car-mounted terminal more complicated by the elastic contact chip that arranges on the fixed-conductive film that arranges on the data trap and the car-mounted terminal, simultaneously the fixed contact piece on elastic contact chip and the data trap once a day or cliding friction for several times will cause the severe wear of contact portion, causing that power supply lost efficacy.
Summary of the invention
The utility model is at the proposition of above problem, and develops a kind of intelligent vehicle mounted terminal to the structure of data trap power supply.The technical solution adopted in the utility model is as follows:
A kind of intelligent vehicle mounted terminal is characterized in that to the structure of data trap power supply:
Intelligent vehicle mounted terminal is provided with the power supply contact jaw that voltage is provided for external device;
Data trap is provided with the power spring pin that is connected to the data trap power supply with extraneous electric supply installation;
During use, the power spring pin of the power supply on the data trap is closely contacted with the power supply contact jaw on the intelligent vehicle mounted terminal.
Described data trap is provided with for the permanent magnet II that data trap is absorbed and fixed on the intelligent vehicle mounted terminal; Described intelligent vehicle mounted terminal is provided with permanent magnet II position corresponding, and the permanent magnet I that can inhale mutually with the permanent magnet II.
Described data trap is provided with the positioning boss for the location; Corresponding intelligent vehicle mounted terminal is provided with the positioning boss position corresponding, and the detent that is complementary with positioning boss.
Electric power-feeding structure described in the utility model, it is apparent comparing advantage with prior art, owing to adopt externally fed, eliminated the handling problem of battery charge and old and useless battery, simultaneously can do data trap very little, fixed form just can adopt magnetic-type fixing like this, makes the harvester total become simple, light; In addition, intelligent vehicle mounted terminal can guarantee to provide lasting, stable power supply for data trap.Because it is simple in structure, not only is convenient to produce, and with low costly is suitable for extensive popularization.
Description of drawings
The utlity model has a width of cloth accompanying drawing:
Fig. 1 is the structural representation of electric power-feeding structure described in the utility model.
The specific embodiment
Intelligent vehicle mounted terminal as shown in Figure 1 is to the structure of data trap power supply, and wherein intelligent vehicle mounted terminal 1 is provided with the power supply contact jaw 11 that voltage is provided for external device; Data trap 2 is provided with the power spring pin 21 that is connected to data trap 2 power supplies with extraneous electric supply installation; During use, the power spring pin 21 of the power supply on the data trap 2 is closely contacted with the power supply contact jaw 11 on the intelligent vehicle mounted terminal 1.Described data trap 2 is provided with for the permanent magnet II 22 that data trap 2 is absorbed and fixed on the intelligent vehicle mounted terminal 1; Described intelligent vehicle mounted terminal 1 is provided with permanent magnet II 22 positions corresponding, and the permanent magnet I 12 (being that permanent magnet II 22 is opposite with the polarity of permanent magnet I 12 opposite faces) that can inhale mutually with permanent magnet II 22, because the adsorption of permanent magnet, data trap 2 is fixed on the intelligent vehicle mounted terminal 1, it is compressed to make that simultaneously power spring pin 21 and power supply contact jaw 11 contact its inner spring of back, because the effect of spring guarantees that the front end of power spring pin 21 closely contacts with power supply contact jaw 11.Described data trap 2 is provided with the positioning boss 23 for the location; Corresponding intelligent vehicle mounted terminal 1 is provided with positioning boss 23 positions corresponding, and the detent 13 that is complementary with positioning boss 23, and this structure can guarantee that data trap 2 and intelligent vehicle mounted terminal 1 accurately locate.
When intelligent vehicle mounted terminal and data trap by infrared when carrying out data transmission, the advantage of this electric power-feeding structure is particularly evident: because adopt externally fed, data trap can be done very for a short time, during use, by magnetic force data trap is fixed on the intelligent vehicle mounted terminal, can guarantee the stability of stationary state fully, and intelligent vehicle mounted terminal can guarantee the power supply that provides lasting, stable.In addition, the location by boss and groove guarantees that the power supply contact jaw accurately contacts and the accurate contraposition of data transmission mouth.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and inventive concept thereof, all should be encompassed within the protection domain of the present utility model.
