Abstract
The utility model discloses drive recorder electric supply installation, comprise the input line, voltage conversion device and the output interface that are electrically connected successively, voltage conversion device comprises housing and is built in the voltage conversion circuit plate of this housing, voltage conversion circuit plate has input and output, output interface is fixed on voltage conversion circuit plate and is electrically connected with described output, and input line to penetrate in housing and is electrically connected with described input.The utility model can avoid the electromagnetic interference of modular converter, is also beneficial to the heat radiation of this modular converter simultaneously.
Description
Technical field
The utility model relates to voltage conversion device, particularly relates to drive recorder electric supply installation.
Background technology
Usual vehicle power supply voltage is 12V, and the equipment nominal input voltage such as most of drive recorder are 5V, therefore needs voltage conversion device to carry out step-down as the electric supply installation forming recorder.The existing voltage conversion device forming recorder that is applied on the market generally comprises the input line connected successively, modular converter, output line and output interface, because cable is more, this electric supply installation of car domestic demand Zang Na, therefore, input line, modular converter, output line all will be contained in roof by Tibetan, be unfavorable for the maintenance of modular converter, and, because modular converter voltage is lower, be vulnerable to other interference of electromagnetic field in roof, more crucially be, the amount of heat that modular converter operationally gives out will be difficult to shed, modular converter is caused to work at relatively high temperatures for a long time, reduce useful life.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide drive recorder electric supply installation, can avoid the electromagnetic interference of modular converter, is also beneficial to the heat radiation of this modular converter simultaneously.
The purpose of this utility model realizes by the following technical solutions:
Drive recorder electric supply installation, comprise the input line, voltage conversion device and the output interface that are electrically connected successively, voltage conversion device comprises housing and is built in the voltage conversion circuit plate of this housing, voltage conversion circuit plate has input and output, output interface is fixed on voltage conversion circuit plate and is electrically connected with described output, and input line to penetrate in housing and is electrically connected with described input.
Preferably, housing comprises body, plug and capping, and plug is plugged in one end mouth of pipe of body, and this plug Fixing shrink ring is in voltage conversion circuit plate, and output interface is fixed in this plug; Capping is plugged in the other end of body, this capping has the perforation penetrated for input line.
Preferably, output interface is MicroUSB interface or MiniUSB interface.
Preferably, housing is made up of metal material or plastics, and plug and capping are made up of insulating material respectively.
Compared to existing technology, the beneficial effects of the utility model are:
Output interface is set directly at the position near voltage conversion device by the utility model, therefore, after output interface is plugged on the power input forming recorder, voltage conversion device will expose, and be output interface and directly support unsettled, therefore, this voltage conversion device can avoid the interference being subject to roof electromagnetic signal, good heat radiation can also be formed, can be dispelled the heat further by air louver in aid vehicle, meanwhile, only input line is positioned at roof inside, therefore its mounting or dismounting are easy, are beneficial to maintenance.
Accompanying drawing explanation
Fig. 1 is one of perspective view of the utility model drive recorder electric supply installation;
Fig. 2 is the perspective view two (saving input line) of the utility model drive recorder electric supply installation;
Fig. 3 is the exploded view (saving input line) of the utility model drive recorder electric supply installation.
In figure: 1, input line; 2, voltage conversion device; 21, housing; 211, body; 212, plug; 213, capping; 214, bore a hole; 22, voltage conversion circuit plate; 3, output interface.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
Drive recorder electric supply installation as shown in Figures 1 to 3, comprise the input line, voltage conversion device and the output interface that are electrically connected successively, voltage conversion device comprises housing and is built in the voltage conversion circuit plate of this housing, voltage conversion circuit plate has input and output, output interface is fixed on voltage conversion circuit plate and is electrically connected with described output, and input line to penetrate in housing and is electrically connected with described input.
Output interface is set directly at the position near voltage conversion device, therefore, after output interface is plugged on the power input forming recorder, voltage conversion device will expose, and be output interface and directly support unsettled, therefore, this voltage conversion device can avoid the interference being subject to roof electromagnetic signal, good heat radiation can also be formed, increase the service life, can be dispelled the heat further by air louver in aid vehicle, simultaneously, only input line is positioned at roof inside, and therefore its mounting or dismounting are easy, are beneficial to maintenance.
Wherein, voltage conversion circuit plate is the board structure of circuit can changed voltage of existing routine.Drive recorder situation is applied to for this example, voltage conversion circuit plate 12V being converted to 5V can be adopted.
As one preferred embodiment, for forming effective protection to voltage conversion circuit plate, there is provided again good mounting or dismounting performance simultaneously, the housing of this example comprises body, plug and capping, plug is plugged in one end mouth of pipe of body, and this plug Fixing shrink ring is in voltage conversion circuit plate, output interface is fixed in this plug; Capping is plugged in the other end of body, this capping has the perforation penetrated for input line.Plug both played plugging action, played again the effect being fixedly connected with output interface, to realize the good effect of being tightly connected to output interface.
The output interface of this example is MicroUSB interface, also can adopt MiniUSB interface.
For the benefit of dispel the heat, ensure again the insulation property of output interface, input line, housing is made up of metal material or plastics simultaneously, and such as adopt iron or Steel material to make, plug and capping are made up of insulating material respectively, such as, adopt plastic material to make.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection range of the utility model claim.
