Abstract
The utility model relates to a vibration attenuation interior mirror which comprises a mirror body, wherein the mirror body comprises a shell and a mirror plate; a vibration attenuation mechanism is arranged in the shell and comprises connection rubber and a mass block; the connection rubber is fixed in an inner cavity of the shell; the mass block is fixed on the connection rubber; a flanging capable of covering the mirror plate is arranged on the rim of the shell; the top of the flanging is inwards bent and covers the peripheral part of the mirror plate; the rim of the connection rubber is clamped between the flanging and the rim of the mirror plate after extending towards the flanging. The vibration attenuation interior mirror can prevent the mirror plate from being loosened and also prevent a driver from being dizzy when the driver observes the mirror.
Description
Technical field
The utility model relates to a kind of accessory of automobile, is specifically related to a kind of vibration damping room mirror.
Background technology
Internal car noise is one of essential items for inspection of dispatching from the factory of car load, is also the important indicator of evaluating vehicle NVH performance, and along with the development of auto-industry, customer pays close attention to the travelling comfort of vehicle more, and the requirement that vehicle noise is controlled is stricter.The generation of vehicle noise is except the exciting sources such as driving engine, tire, air stream, and the mode of body structure transmitting vibrations is also the main contributor that produces noise.For example, front windshield glass of car is generally fixed on Metal Sheets for Body-manufacturing by glass cement, because glass cement quality is soft, rigidity is little, constraint ability relatively a little less than, when enough large to the exciting force of tire from driving engine or road surface, thereby front windshield will resonate and cause thundering in car, affect car load NVH performance.For addressing the above problem, there is at present a kind of room mirror for vehicle front windshield vibration and noise reducing, it comprises driving mirror bracket and body of backsight mirror, driving mirror bracket is fixed on front windshield glass of car, described body of backsight mirror comprises housing and rear view mirror lens, described housing is arranged on driving mirror bracket, is symmetrical set two groups of damper mechanisms in housing.Damper mechanism comprises and connects rubber and mass, and described connection rubber is fixed in housing inner chamber, described mass be fixed on connect rubber above.
The principle of work of above-mentioned back mirror is: the mass in its damper mechanism has at inhibition effect of vibration, and its radical function shows in the following areas, the one, and the vibrational energy that decay is transmitted along structure; The 2nd, weaken near the vibration of resonance frequency; The 3rd, the vibration that reduces free vibration of structures or caused by impact.When making front windshield glass produce vibration from driving engine or road surface to the exciting force of tire, be positioned at the mass absorbing vibrational energy of housing, weaken the vibration amplitude of front windshield glass, reach the object that reduces the roar in car.But because eyeglass and housing are clamping relations, therefore, when driving, after housing is vibrated, a part of vibration can be directly delivered on eyeglass, still can cause eyeglass to produce vibration, cause chaufeur dizzy when observing back mirror.
Summary of the invention
For above-mentioned technical matters, main purpose of the present utility model is, a kind of chaufeur dizzy vibration damping room mirror when observing back mirror that prevents is provided.
The technical scheme solving the problems of the technologies described above is as follows:
Vibration damping room mirror, comprise body of backsight mirror, body of backsight mirror comprises housing and eyeglass, in housing, be provided with damper mechanism, damper mechanism comprises connection rubber and mass, described connection rubber is fixed in housing inner chamber, described mass is fixed on and connects above rubber, the edge of described housing is provided with the flange in eyeglass is wrapped in, the top of described flange bends inwards and covers on the periphery position of eyeglass, the edge of described connection rubber is clamped between flange and eyeglass after extending to flange.
Further, the back side of described eyeglass is provided with heater strip.
Adopted such scheme, the edge of described housing is provided with the flange in eyeglass is wrapped in, the top of described flange bends inwards and covers on the periphery position of eyeglass, and this structure can be securely fixed in eyeglass in housing, avoids eyeglass to occur in housing loosening.The edge of described connection rubber is clamped between flange and eyeglass after extending to flange, by connecting rubber, effect of vibration power is absorbed, and can form damping of vibrations to eyeglass, avoids chaufeur to occur when observing back mirror dizzy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
1 is housing, and 2 is eyeglass, and 3 for connecting rubber, and 4 is mass, and 5 is flange, and 6 is heater strip.
The specific embodiment
See figures.1.and.2, a kind of vibration damping room mirror of the present utility model, comprises body of backsight mirror, and body of backsight mirror comprises housing 1 and eyeglass 2, and the back side of described eyeglass is provided with heater strip 6.In housing, be provided with damper mechanism, damper mechanism comprises connection rubber 3 and mass 4, and described connection rubber 3 is fixed in housing 1 inner chamber, and described mass 4 is fixed on and connects above rubber 3.The edge of described housing is provided with the flange 5 in eyeglass is wrapped in, and the top of described flange bends inwards and covers on the periphery position of eyeglass, and the edge of described connection rubber 3 is clamped between flange and eyeglass after extending to flange.
Claims (2)
1. vibration damping room mirror, comprise body of backsight mirror, body of backsight mirror comprises housing and eyeglass, in housing, be provided with damper mechanism, damper mechanism comprises connection rubber and mass, described connection rubber is fixed in housing inner chamber, described mass is fixed on and connects above rubber, it is characterized in that: the edge of described housing is provided with the flange in eyeglass is wrapped in, the top of described flange bends inwards and covers on the periphery position of eyeglass, the edge of described connection rubber is clamped between flange and the edge of eyeglass after extending to flange.
2. vibration damping room mirror according to claim 1, is characterized in that: the back side of described eyeglass is provided with heater strip.
