JPH0678171U - Dynamic damper using fire extinguisher - Google Patents

Abstract

(57) [Abstract] [Purpose] By attaching a fire extinguisher to a vibration generating portion of a vehicle, particularly an automobile, the vibration amplitude of the vibration generating portion is reduced. [Structure] A fire extinguisher 5 is fastened by a fastening member 6 with an elastic body 4 interposed in a vibration generating portion 1 which constitutes a part of a vehicle body to form a dynamics damper.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The idea of this invention is to install the fire extinguisher over the joint between the back panel of the cabin and the floor of the cargo bed, which is a problematic part of the vibration of the vehicle, especially of the truck body. I try to make it smaller.

[0002]

[Prior art]

 Conventionally, an on-vehicle fire extinguisher is merely mounted on a part of the vehicle body. On the other hand, in order to reduce the resonance amplitude of the vibration generating part of the vehicle body, a vibration absorber consisting of a mass, a spring, and a dump pot was attached to the vibration generating part as a dynamic damper.

[0003]

[Problems to be solved by the device]

 Since both the fire extinguisher and the dynamic damper are factors that increase the weight of the vehicle body, the purpose of the present invention is to reduce the weight of the fire extinguisher and the dynamic damper.

[0004]

[Means for Solving the Problems]

 Here, the present invention proposes a dynamic damper using a fire extinguisher in which an elastic body is interposed in a vibration generating portion forming a part of a vehicle body and a fire extinguisher is fastened with a fastening member. .

[0005]

[Action]

 In this device having the above structure, the dynamic damper was separately mounted by adding the function of the dynamic damper to the conventional fire extinguisher mounted on the vehicle as a safety device. The weight of the vehicle body can be reduced compared to the conventional example.

[0006]

【Example】

 In FIG. 1 and FIG. 2, reference numeral 1 denotes a back panel 2 of a cabinet as a vibration generating part which constitutes a part of a vehicle body, and a floor 3 of a loading platform connected to the back panel 2. In the present invention, this vibration generating part is shown. 1, the fire extinguisher 5 is fastened by the fastening member 6 via the elastic body 4 such as a rubber mat. In the illustrated embodiment, the elastic body 4 is provided between the fire extinguisher 5 and the back panel 2 at two places and between the fire extinguisher 5 and the floor 3, but the present invention is not limited to this form.

In FIG. 3, the fastening member 6 has a pair of elastic C-shaped cross-section receivers 7 and 8 attached to the back panel 2, and a curved shape that follows the outer surface shape of the fire extinguisher 5. A fitting body 12 having cylindrical portions 10 and 11 which can be fitted to the receiving bodies 7 and 8 is formed at both ends of the portion 9.

The structure of the fastening member 6 shown in FIG. 3 does not limit the technical scope of the invention, and all other conceivable fastening means can be applied.

According to the above-mentioned structure of the present invention, the mass (mass) of the fire extinguisher 5 itself acts as a dynamic damper, thus reducing the amplitude of the vibration generating portion 1 at resonance. .

[0010]

[Effect of device]

 As described above, according to this invention, the fire extinguisher mounted on the vehicle can play the role of a dynamic damper, so that it is not necessary to separately install a dynamic damper, and the weight of the vehicle body can be reduced accordingly. While reducing the fire extinguisher, it can be used for its original purpose of use, and is a device with a high practical utility value.
