Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Examples

As shown in fig. 1, an invisible door guide rail assembly with noise reduction function, includes door frame 2 and door body 1, door body 1 passes through guide rail 3 subassembly and door body 1 sliding connection, the guide rail 3 subassembly includes the guide rail 3 at door frame 2 top, the both sides of guide rail 3 are equipped with a plurality of relative gyro wheel 4 groups, and relative gyro wheel 4 is a set of promptly, and relative gyro wheel 4 passes through T type pole 5 and connects, T type pole 5 is made by the honeycomb panel, and the lower extreme of T type pole 5 stretches out and with door body 1 fixed connection from the guide rail 3 opening. The door body 1 is connected with the door frame 2 in a sliding way through a guide rail 3 assembly consisting of the T-shaped rod 5, the roller 4 group and the guide rail 3, and a small gap exists between the upper end and the lower end of the door body 1 and the door frame 2, so that the door body 1 cannot rub against the edge of the door frame 2 in the pushing and pulling process, and the collision noise of the door body 1 and the door frame 2 can be reduced; secondly, the T-shaped rod 5 is made of a honeycomb plate, the inside of the T-shaped rod is of a honeycomb structure, the pores are communicated with each other and filled with air, as is known, the sound propagation speed in the air is the slowest, so the sound propagation can be effectively prevented, secondly, the noise generated by the collision of the roller 4 and the guide rail 3 passes through the T-shaped rod 5, the honeycomb core 51 in the T-shaped rod absorbs vibration and is converted into the deformation energy of the core material to be slowly released, so the noise is greatly attenuated, in addition, after the sound wave enters the honeycomb core 51, the vibration of the air and the material can be caused, and a part of sound energy is converted into heat energy to be dissipated due to the friction and viscous resistance of air molecules, so the noise is effectively reduced, the sound insulation.

In this embodiment, the honeycomb core 51 of the honeycomb plate is made of one of aramid paper honeycomb, glass cloth honeycomb, aluminum honeycomb, graphite honeycomb, kraft paper honeycomb, stainless steel honeycomb, and cotton cloth honeycomb.

In this embodiment, the honeycomb panel is filled with a sound absorbing material (not shown). The porosity and viscous resistance are increased through the sound-absorbing material, and the sound-absorbing material is subjected to mechanical vibration, so that sound energy is lost and converted into heat energy, the vibration caused by solid-borne sound and air is weakened, and the sound-absorbing effect is enhanced; secondly, the honeycomb plate and the sound absorption material are used in a composite mode, so that the sound absorption range can be expanded, and the sound absorption coefficient can be improved.

In this embodiment, the sound absorbing material is one or more of organic fiber, inorganic fiber, foam glass, and foam plastic. The organic fiber, the inorganic fiber, the foam glass and the foam plastic are all loose and porous materials, so that sound waves are refracted and rubbed in gaps, the propagation path is greatly increased, more sound energy is converted into heat energy and structural deformation energy, and the transmission of the sound waves is effectively prevented.
