Abstract

The invention described is a controlled environment designed to house automotive onboard electronics. In general, the vibration and impact a moving vehicle experiences is detrimental to certain electronic components such as hard disk drives. Only the high-end automobiles that are equipped with elaborated shock absorbing devices may provide a suitable operating environment for these delicate electronics. Based on a completely different approach, this invention is to create a controlled space with a novel apparatus to reduce the shock and vibration within its domain regardless of what the automobile experiences. Therefore, the electronic components that reside inside this controlled space will experience far less severe impact thus enhance their chance of survival.

Claims

1. A shock reducing apparatus, for automotive electronic devices, which consists of a first liquid tight containing vessel and a smaller second liquid tight containing vessel, such that the to-be protected electronics resides inside the said second containing vessel while it resides inside the said first containing vessel and the space in between of the said first and second containing vessels is filled with fluid of appropriate density and viscosity to provide proper buoyancy.

2. In a shock reducing apparatus of claim 1, both the said containing vessels have at least one liquid tight outlet such that the electronic connection cable of the to-be-protected electronics can pass through the said outlet in a liquid tight fashion to reach the exterior of the said second containing vessel and routing loosely in the fluid to pass the said liquid tight outlet of the said first containing vessel into the exterior of it.

3. In a shock reducing apparatus of claim 2, there may be springs of appropriate spring constant mechanically connecting the exterior of the said smaller second containing vessel to the interior of the said first containing vessel, such that the springs are relatively relaxed in conjunction with the buoyancy while the said containing vessels are maintained in the nominal position.

4. In an automobile shock reducing apparatus of claim 3, airbag type floatation devices maybe attached to the sides of the said second containing vessel to provide extra buoyancy in order to give additional measures for proper matching in between of the mass and the volume of to-be-protected device(s), the spring constant and the density of the fluid.
