  • Patent number: 8893839
    Abstract: A battery cooling structure for a vehicle includes: a vehicle body floor part; and a battery module that is located under the vehicle body floor part, and that is arranged such that a clearance is formed between the battery module and the vehicle body floor part and an airflow that is introduced from the front side of a vehicle body into the clearance is discharged from the rear end of the clearance. At least one of the vehicle body floor part and the battery module has a wall portion that is formed so as to gradually decrease the area of a cross-section of the clearance, the cross-section being perpendicular to the longitudinal direction of the vehicle body, along the direction toward the rear of the vehicle body.

  • Patent number: 8863877
    Abstract: A vehicle battery mounting structure includes a first frame member, a battery unit, a coupling portion, and a brittle portion. The first frame member supports a vehicle floor and includes a front portion, an inclined portion and a rear portion. The inclined portion extends rearward from a rear end of the front portion in a front-rear direction of the vehicle and upward from the rear end in a vertical direction of the vehicle. The battery unit is disposed under the vehicle floor. The coupling portion couples the battery unit to the inclined portion or a second frame member connected to the inclined portion. The brittle portion is provided at the coupling portion and releases the inclined portion or the second frame member from a connection with the battery unit when a forward load is applied to the coupling portion in the front-rear direction of the vehicle.

  • Patent number: 8779670
    Abstract: A lighting device includes a pyroelectric sensor, a shutter and a lighting control unit. The lighting control unit is configured, when the lighting load is turned off, to turn the lighting load on if the pyroelectric sensor detects a change in infrared radiation. The lighting control unit is also configured, when the lighting load is turned on, to turn the lighting load off if a repetition count or time of a lighting retention time reaches a specified count or time, respectively, with no change in infrared radiation detected through the pyroelectric sensor within each lighting retention time per the passage of lighting retention time.

  • Publication number: 20140015421
    Abstract: An LED module includes a light-emitting unit composed of a plurality of LEDs connected in series to one another, a sensor unit, a power interrupt circuit inserted into a power supply path through which the light-emitting unit is supplied with power from an external power source, and a control circuit that controls the power interrupt circuit according to output of the sensor unit. The LED module further includes a secondary battery and a voltage supply circuit. The voltage supply circuit supplies the control circuit with voltage equivalent to voltage drop between the ends of a group of LEDs included in the plurality of LEDs that constitute the light-emitting unit while the external power source is supplying power to the light-emitting unit, and supplies the control circuit with voltage output from the secondary battery while power interrupt circuit is interrupting the power from the external power source to the light-emitting unit.

  • Publication number: 20130270853
    Abstract: A structural body part and a method of assembling a structural body part are provided. The structural body part includes an inner wall surface defining an enclosed space. A nut is disposed within the enclosed space. The structural body part includes an aperture for receiving a fastener so as to accommodate the addition of additional structure. The body structure includes a spacer. The nut is attached to the spacer. The spacer is configured to suspend the nut above the inner wall surface of the structural body part. Thus, the inner wall surface of the structural body part is exposed and covered with a solution when submersed therein.

  • Publication number: 20130127200
    Abstract: A service hole cover has a housing recessed portion that has been brought from above the vehicle floor toward the battery unit through the service hole through a service hole formed in a floor panel from inside a vehicle cabin, and that covers an upper portion of a power supply circuit interrupting device from the floor panel side. An extended portion that extends toward an outside of the housing recessed portion is provided on a lower end portion of an inner peripheral wall portion of this housing recessed portion. Also, a bent-back portion that is bent back toward the floor panel side is provided on an outer peripheral side end portion of the extended portion. This bent-back portion will easily deform toward the inner peripheral wall portion side of the housing recessed portion with the outer peripheral side end portion of the extended portion as the fulcrum.

  • Patent number: 5711562
    Abstract: A bumper assembly is effective to prevent stepped walls of a concave portion of a bumper cover from being sharply deformed. Cavities are formed at parts of an energy absorber facing to a bottom wall of the concave portion of the bumper cover to define spaces behind the bottom wall. The stepped walls are moved in the cavities of the energy absorber when the energy absorber is deformed elastically in collision.
