The invention relates to the technical field of driving box bodies, and discloses a buffer noise reduction device for a driving box body, the buffer noise reduction device comprises a protective shell, the left side of the protective shell is fixedly connected with a baffle, the left side of the baffle is in threaded connection with a fixing screw, and two supporting frames are fixed in the bottom end of the protective shell; a sound absorption plate is fixedly installed in the supporting frame at the top end, a sound insulation plate is fixedly installed in the supporting frame at the bottom end, and a dustproof plate is fixedly connected to the top of the protective shell. According to the buffer noise reduction device for the driving box body, the box body pushes a push plate, a damping spring outside a limiting rod is extruded, the impact force of the box body can be relieved, a dustproof plate can prevent dust or particulate matter from entering the interior to affect the buffer effect of the damping spring, and a sound absorption plate inside a top end supporting frame can absorb noise generated in the operation process of the box body; and if part of noise passes through the acoustic panel, the noise can be rebounded by the acoustic panel, so that the noise is reduced.
Description
technical field [0001] The invention relates to the technical field of driving boxes, in particular to a buffering and noise reduction device for driving boxes. Background technique [0002] The box body is usually made of gray cast iron. Gray cast iron has good casting performance and vibration damping performance. For heavy load or impact load, the box body generally refers to the base of the transmission parts and should have sufficient strength and rigidity. [0003] Some types of vehicles have their own cabinets. The driving cabinets can store items and are mostly used for transportation. However, due to the large number of items stored in the driving cabinets, it is easy to cause certain damage to the driving cabinets when the vehicle stops suddenly. The box body vibrates with the driving of the vehicle, and it is easy to emit a lot of noise, so a buffer and noise reduction device for driving box body is proposed to solve the above-mentioned problems.
