Problems solved by technology

Even if the sealing member 64 is extended to seal the gap at this part, it is still difficult to completely extend the sealing member 64 to the corner gap in consideration of manufacturing tolerances, etc.
In such a case, it is impossible to completely prevent the intrusion of dust or water droplets from the part of the gap GP
For example, when a vehicle-mounted power supply unit is required, there may be a need for a structure that can prevent the intrusion of dust of 75 μm or less, and the existing structure cannot fully meet this demand

Embodiment 1

[0113] based on Figure 1 to Figure 15 , an example in which the power supply device according to Embodiment 1 is applied to a vehicle-mounted power supply device will be described. The power supply device shown in the above figure is mainly suitable as a power source for electric vehicles such as a hybrid vehicle that runs on both an engine and an electric motor, or an electric vehicle that runs only on an electric motor. Among them, the power supply device of the present invention can be used in vehicles other than hybrid vehicles and electric vehicles, and can also be used in applications requiring large output other than electric vehicles. In addition, in addition to the power supply unit, the housing is also provided with a control device for accommodating the circuit, etc., and the housing can be used as a dustproof function for improving mechanical strength and protecting internal components from intrusion of dust, or for protecting the inside. The member is used as a ...

Embodiment 2

[0159] In addition, in the above-mentioned example, the structure which divided the casing into three parts except the side plate and two cover plates was demonstrated, but this invention is not limited to this structure. For example, it can also be applied to a structure in which the casing is divided into two, an upper casing and a lower casing. exist Figure 16 Such a structure is shown in Example 2. The case of the power supply unit 100B shown in the figure is composed of a base plate 4B with an upper opening and a cover plate 5B that closes the opening of the base plate 4B. The cover plate 5B closes the opening in a dust-proof state via the sealing member 15 and is fixed by a fixing member. The base plate 4B is formed in a box shape with an upper opening, and accommodates the battery block 2, electronic components, and the like inside. The base plate 4B has a cover mounting surface 4a' around it, and the upper edge of the cover mounting surface 4a' is connected to the ...

Abstract

The invention provides a power source apparatus capable of blocking gap generated between attachment interfaces of housings reliably and improving dust-free performance, and a vehicle and a dust-free case equipped with the power source apparatus. The power source apparatus has a sealing component (15) having flexible projections (44) extending in the lengthwise direction and intervening between cover-attachment-surfaces (4a) on a base-plate (4) and base-attachment-surfaces (8a) on a cover-plate (5). Ends of the cover-plate (5) are provided with hood segments (8b) that extend from the base-attachment-surfaces in a direction approximately perpendicular to the attachment-surfaces and cover the sides of the sealing component (15) and the cover-attachment-surfaces. In addition, sealing pieces (16) are provided between the cover-plate and the sealing material in a manner that extends continuously from the base-attachment-surface to the hood segment. With sealing material intervening between cover-attachment-surfaces and base-attachment-surfaces, base-plate and cover-plate attachment-surfaces are sealed together with the sealing pieces compressed on top of the flexible projections.

Description

technical field [0001] The present invention relates to a power supply device for large currents mainly used for power supply for driving a motor of a motor vehicle such as a hybrid vehicle or an electric vehicle, for storing electricity in a household or in a factory, a vehicle equipped with such a power supply device, and an anti-corrosion device. dust case. Background technique [0002] Motor vehicles such as electric vehicles that run on electric motors or hybrid cars that run on both electric motors and engines are equipped with a power supply device that is formed by housing a plurality of battery cells in a case. . In order to drive a motor vehicle with an electric motor, the power supply device needs to increase the output, and therefore, a plurality of battery cells are connected in series to increase the output voltage. For example, the voltage of a storage battery for electrical equipment mounted on a motor vehicle is often 12V, but the output voltage of a power...
