Benefits of technology

[0008]An objective of the invention is to provide a power driven compressor system for vehicles. The compressor is completely driven by electrical power. During its operation, the compressor has a better cooling effect.

Problems solved by technology

However, in view of the rising oil price and limited natural resources, all carmakers have been trying to develop electric cars.
Nevertheless, current power driven compressor systems (e.g., those in refrigerators) cannot be directly used in vehicles.
Since running vehicles must have vibrations, home electronic compressor systems cannot be applied to vehicles.
Moreover, as the environmental temperature due to the vehicle operation is higher, the compressor motor tends to overheat and lowers its efficiency.
The high environmental temperature also has the problem of circuit damages in the compressor system.

Embodiment Construction

[0017]The present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.

[0018]First, please refer to FIGS. 1 to 3 for the power driven compressor system for vehicles according to the invention. It includes a housing 11, a transmission set 21, and a scroll set 31.

[0019]The housing 11 consists of a bottom cover 12 and an end cover 13. The bottom cover 12 has an air inlet 14. The end cover 13 has an air outlet 15. The bottom cover 12 is fonned with a driving circuit accommodating room 16 in communications with the interior thereof and having an open end 161. A sideboard 17 correspondingly covers the open end 161 of the driving circuit accommodating room 16, blocking its communications with the external space. Two opposite concave parts 121 are formed around the open end of the bottom cover 12.

[0020]The transmission set 21 is disposed in the bottom cover 12. ...

Abstract

A power driven compressor system for vehicle includes: a housing, formed with a driving circuit accommodating room; a transmission set disposed in the housing and driven by electrical power to produce a rotating magnetic for rotating a transmission axle; a scroll set comprised of a static scroll and a orbiting scroll. The orbiting scroll is driven by the transmission axle to rotate eccentrically with respect to the static scroll. An Oldham ring is disposed between the orbiting scroll and the housing. The Oldham ring has a cross-like limiting part. A concave part corresponding to the limiting part is formed on the housing and the orbiting scroll to limit the motion of the orbiting scroll.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of Invention[0002]The invention relates to a compressor and, in particular, to a power driven compressor system for vehicles.[0003]2. Related Art[0004]A normal vehicle compressor system utilizes the power of gas engine for its operation. However, in view of the rising oil price and limited natural resources, all carmakers have been trying to develop electric cars. Therefore, it is a natural trend for vehicle compressor systems to use electrical power.[0005]Nevertheless, current power driven compressor systems (e.g., those in refrigerators) cannot be directly used in vehicles. The reason is as follows.[0006]Ordinary home electronic compressor systems are formed with a room for holding coolant oil at their bottom. When the compressor is running, the coolant oil is simultaneously sucked up to lubricate the internal components of the compressor. Therefore, the home electronic compressors can only run is a static environment. This is to prevent d...
