Abstract
The utility model relates to a dynamic vibration absorber technical field especially relates to a seat dynamic vibration absorber can be dismantled to low frequency, including support and quality piece, the outside parcel of quality piece has the rubber layer, and the both sides on rubber layer outwards extend and form the elastomer, the elastomer inserts in the assembly hole of support both sides and rather than closely cooperating, support upper portion is inwards bent and is formed the engaging lug, the riveting has assembly bolt or welding to have assembly nut on the engaging lug. The device has simple structure, practicality and lower cost, and can absorb the vibration of the seat. Assembling a mass block wrapped by rubber and a bracket, wherein a rubber part between the mass block and the bracket forms an elastic body to play a damping role; the dynamic vibration absorber is connected with the seat support through bolts through metal plates, and the installation and the disassembly are very convenient.
Description
Technical Field
The utility model relates to a dynamic vibration absorber technical field especially relates to a seat dynamic vibration absorber can be dismantled to low frequency.
Background
The automobile seat is an indispensable part in the existing automobile, and can provide a driving and sitting position which is convenient to operate, comfortable and safe for drivers and passengers. The existing automobile seat generally meets the following conditions: the arrangement of the seats in the whole carriage is reasonable, and particularly, the driver seat must be in the optimal position; the appearance design of the chair must accord with the physiological function of human body, and the appearance is attractive on the premise of ensuring the comfort; the seat must be safe and reliable, should have sufficient strength, rigidity and durability, compact structure and reduce the mass as much as possible; in order to satisfy the comfort of drivers and passengers, various adjusting mechanisms are provided with reliable locking devices to ensure safety.
Although the automobile seat is developed more mature, the automobile seat is always in a fixed state in the running process of an automobile, the automobile seat cannot buffer and absorb shock to a certain extent when the road is bumpy, and the waist and the hip of a driver are easily injured mechanically.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the not enough of above-mentioned technique, and provide the low frequency can dismantle seat power vibration absorber.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: the utility model provides a seat dynamic vibration absorber can be dismantled to low frequency which characterized in that: the elastic support comprises a support and a mass block, wherein a rubber layer wraps the outside of the mass block, two sides of the rubber layer extend outwards to form an elastic body, the elastic body is inserted into assembly holes in two sides of the support and is tightly matched with the assembly holes, the upper portion of the support is bent inwards to form a connecting lug, and an assembly bolt or a welding nut is riveted on the connecting lug.
Preferably, the assembly hole is racetrack shaped.
Preferably, the mass is cylindrical in shape or other shape.
Preferably, the tail end of the elastic body is provided with an annular or oval clamping groove for fixing with the assembling hole.
Compared with the prior art, the utility model has the advantages of simple structure, practicality, low cost and vibration absorption for the chair. Assembling a mass block wrapped by rubber and a bracket, wherein a rubber part between the mass block and the bracket forms an elastic body to play a damping role; the dynamic vibration absorber is connected with the seat support through bolts through metal plates, and the installation and the disassembly are very convenient.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a plan view of the present invention.
Detailed Description
The following detailed description of the preferred embodiments of the present invention is provided in connection with the accompanying drawings. As shown in figure 1 and figure 2, the low-frequency detachable seat dynamic vibration absorber is characterized in that rubber 3 and a mass block 2 are integrally vulcanized and then assembled with a support 1, assembly holes at two ends of the support 1 are in a track shape, and the shape of the assembly position corresponding to the rubber 3 is also in the track shape, so that the product is prevented from rotating in the movement process, the support is prevented from cracking the rubber, and the durability of the product is improved;
the elastic body 301 is cylindrical in structure, the natural frequencies of the dynamic vibration absorber in the X direction and the Z direction are consistent, and the problem that the X direction or the Z direction or the X/Z direction of a vehicle body has the same resonance frequency can be solved;
the riveting screw on the bracket, or the welding nut 302, can be selected according to the assembling requirements of customers.
The low frequency seat power vibration absorber is installed on the support below the headrest, and after the power vibration absorber is installed, when the seat resonates, the resonance frequency of the power vibration absorber is consistent with the resonance frequency of the seat, so that the resonance can be transmitted to the power vibration absorber, and the reverse acting force generated when the power vibration absorber resonates can reduce the vibration of the seat, thereby achieving the functions of vibration reduction and noise reduction.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
