Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
The first embodiment is as follows:
referring to fig. 1-2, a power supply for a vehicle includes a supply housing 1, a power supply device is installed in the supply housing 1, a heat dissipation hole 101 is formed in a sidewall of the supply housing 1, an exhaust pipe 3 is fixedly connected to the supply housing 1 and is communicated with an interior of the supply housing, and a windward pipe 2 is fixedly connected to a sidewall of the exhaust pipe 3 and is communicated with the interior of the exhaust pipe.
The power supply device comprises a wind wheel 7 which is rotatably connected to the inner top of the windward pipe 2, and particularly, the wind wheel 7 is a wind cup-shaped wind wheel and can rotate under the blowing of transverse airflow. And one of the blades of the wind wheel 7 is made of magnetic material, the exhaust pipe 3 is connected with a permanent magnet 8 in a sliding mode, when the magnetic blade and the permanent magnet 8 are aligned, the like magnetic poles of the magnetic blade and the permanent magnet are opposite, the permanent magnet 8 overcomes the elastic force of the first spring 9 to move downwards due to the magnetic repulsion force, when the exhaust pipe is manufactured specifically, the exhaust pipe 3 can be made longer, the windward pipe 2 can extend out of the vehicle, and meanwhile the permanent magnet 8 in the exhaust pipe 3 is prevented from interfering with the iron sheet 52. And permanent magnet 8 passes through the interior bottom of first spring 9 elastic connection in blast pipe 3, and blast pipe 3 embeds is equipped with helical coil 10, and helical coil 10 couples in the power supply circuit of electro-magnet 51. In addition, the effective length of the spiral coil 10 is short, so that the permanent magnet 8 can be completely separated from the spiral coil 10 when moving up and down, and when the permanent magnet 8 is separated from the spiral coil 10, the magnetic flux in the spiral coil 10 is zero, so that induction current is not generated, and therefore, the current generated when the permanent magnet 8 moves up and down is intermittent.
When the automobile is installed, the windward pipe 2 can extend out of the automobile, so that when the automobile runs, air flows in the windward pipe 2 at a high speed, the air flow rate of the exhaust pipe 3 communicated with the windward pipe 2 is relatively slow, the Bernoulli principle shows that the pressure intensity generated when the air flow rate is fast is small, the pressure intensity is strong when the air flow rate is slow, therefore, the air pressure of the exhaust pipe 3 is larger than that in the windward pipe 2, hot air in the supplier shell 1 can continuously flow into the windward pipe 2 through the exhaust pipe 3 under the action of the air pressure and is exhausted along with the air flow (the flow direction of the air in the exhaust pipe 3 and the windward pipe 2 can refer to the arrow direction in the windward pipe 2), and external cold air enters the supplier shell 1 through the heat dissipation holes 101 for supplement, so that the heat accumulation in the supplier shell 1 can be effectively avoided to generate high temperature, and the damage of the power supplier.
Meanwhile, when air flows at a high speed in the windward pipe 2, the wind wheel 7 can be pushed to rotate circularly, the magnetic blade of the wind wheel 7 is continuously opposite to the permanent magnet 8, when the magnetic blade is opposite to the permanent magnet 8, the permanent magnet 8 can move downwards and enter the spiral coil 10 under the action of magnetic repulsion, and when the magnetic blade is far away, the first spring 9 pushes the permanent magnet 8 to move upwards for resetting. The permanent magnet 8 can continuously move up and down and enter and exit the spiral coil 10, magnetic flux in the spiral coil 10 is changed when the permanent magnet 8 enters and exits the spiral coil 10, the electromagnet 51 is electrified when induction current is generated, the electromagnet 51 is electrified to generate magnetism, then the iron sheet 52 is attracted to be attached to the electromagnet 51, the pump liquid cylinder 5 is shrunk, and cooling liquid is extruded into the one-way liquid outlet pipe 6; and after the permanent magnet 8 leaves the spiral coil 10 completely, the magnetic flux in the spiral coil 10 becomes zero, the electromagnet 51 is powered off, the pump liquid cylinder 5 expands and recovers under the action of the elasticity of the electromagnet, the cooling liquid can be pumped into the pump liquid cylinder 5 along the one-way liquid inlet pipe 13, so that the pump liquid cylinder 5 can expand and contract continuously, and the cooling liquid is forced to flow along the one-way liquid inlet pipe 13 and the one-way liquid outlet pipe in a one-way circulating manner under the action of the one-way liquid inlet pipe 13 and the one-way liquid outlet pipe 6, so that the heat dissipation efficiency of the device is further improved.
Example two:
referring to fig. 3, unlike the first embodiment, a dust screen 11 is embedded in the feeder housing 1, the dust screen 11 is elastically connected to the inner wall of the feeder housing 1 by a second spring 12, and the second spring 12 is coupled to the spiral coil 10.
Due to dust raised during the driving of the vehicle, the dust inevitably enters the interior of the power supply and gradually accumulates on each electronic component in the power supply equipment, resulting in a reduction in the heat dissipation efficiency of the power supply. Therefore, the dust filtering net 11 is arranged in the power supply device, dust can be effectively prevented from falling on the power supply device in the supply device shell 1, meanwhile, induced current intermittently generated in the spiral coil 10 is continuously led to the second spring 12, the second spring 12 contracts when being powered on, and is extended and recovered when being powered off, the second spring 12 which is continuously stretched can pull the dust filtering net 11 to shake continuously, dust adhered to the outside of the dust filtering net 11 can be shaken off, the dust is prevented from blocking meshes, interaction of air inside and outside the power supply device is difficult, and good ventilation and heat dissipation effects are guaranteed while dust is prevented.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
