Abstract
The utility model relates to the field of automobiles, in particular to a car roof with noise preventing function. The noise preventing car roof comprises a covering plate and a lining plate, wherein the lining plate is fixedly connected with the covering plate; the larger lining plate is fixedly connected with the weak part of the covering plate to strengthen the entire rigidity of the sedan roof, so the roof deformation caused by reasons, such as vibration, air damping and the like when car drives is reduced so as to prevent noise; the binder adhering surface between the lining plate and the covering plate is large, and the craft is simple. The density of synthetic rubber sheets is relatively small, and the vibration absorption is favorable, which can enhance the noise preventing effect of the car roof. In addition the synthetic rubber sheets are odorless and can be recovered.
Description
Technical field
The utility model relates to vehicle on-fixed roof technical field, especially a kind of car roof with its anti-noise function.
Background technology
Car roof is a large-scale covering, the big and thinner thickness of cladding plate area; Reasons such as vibration and air damping when car travels cause the car roof vibration to produce noise, influence the car comfort level; The utility model of patent No. ZL200720124392.8 discloses a kind of car roof structure, employing adds a crossbeam at the car roof middle part, the crossbeam two ends are connected with the covering at gusset top, both sides with attaching parts, the bonded assembly method of crossbeam top and cladding plate makes the car roof cladding plate become the part than a young waiter in a wineshop or an inn, thus noise when reducing car and travelling; Its weak point is: crossbeam is a rigid material, does not have the absorbing effect, so car roof minimizing noise result is not ideal enough, and installs complicated.
Summary of the invention
The purpose of this utility model is to overcome existing reason such as vibration and air damping when travelling because of car, causes the car roof vibration, and the deficiency of generation noise has designed a kind of its anti-noise car roof.
The purpose of this utility model is achieved through the following technical solutions:
A kind of its anti-noise car roof comprises cladding plate, and described its anti-noise car roof has flexible liner plate; Described flexible liner plate is captiveed joint with cladding plate is inboard.Flexible liner plate can be made one or more; Because the bigger flexible liner plate of area is fixedly connected on the inboard of cladding plate, has the absorbing effect, prevented to produce when car from travelling noise.
As preferably: described its anti-noise car roof, adhesive agent is bonding between described liner plate and cladding plate inboard.The bonding joint face of adhesive agent is big and technology is simple, and preferred binder is an epoxy resin.
As preferably: described its anti-noise car roof, the neoprene plate that described flexible liner plate is thickness 1.2～2.5mm.Neoprene plate density is less relatively, and absorbing is good, can strengthen car roof its anti-noise effect; And neoprene plate odorlessness, recyclable.Also can adopt the similar other materials of performance as liner plate.
As preferably: described its anti-noise car roof, described flexible liner plate is 1:2 to 1:4 with the ratio of cladding plate area; Better through testing this ratio its anti-noise effect.
The beneficial effects of the utility model:
The flexible liner plate that area is bigger is fixedly connected on the cladding plate inboard, has the absorbing effect, has absorbed the vibration that top cover produced when car travelled, and has prevented the noise generation, and the car comfort level is improved; Adhesive agent is bonding between flexible liner plate and cladding plate inboard, and joint face is big and technology is simple.
Description of drawings
Fig. 1 is a scheme drawing of the present utility model.
Embodiment
The utility model is as shown in Figure 1: the thickness range 1.2～2.5mm of flexible liner plate 2, embodiment adopt two 2 mm thick; The flexible liner panel material is a neoprene; Neoprene plate density is less relatively, and absorbing can strengthen car roof its anti-noise effect well, and neoprene plate odorlessness, and is recyclable; Two flexible liner plate gross areas are about 1:3 with the ratio of cladding plate 1 area, and are better through testing this ratio its anti-noise effect; Flexible liner plate and cladding plate are inboard uses epoxy bond, and faying face is big and technology is simple.
Have the flexible liner plate that the absorbing active area has the absorbing effect more greatly and be fixedly connected on the cladding plate inboard, have the absorbing effect, absorbed the vibration that top cover produced when car travelled, prevented the noise generation, the car comfort level is improved; Adhesive agent is bonding between flexible liner plate and cladding plate inboard, and joint face is big and technology is simple.
Claims (4)
1. an its anti-noise car roof comprises cladding plate, it is characterized in that: described its anti-noise car roof has flexible liner plate; Described flexible liner plate is captiveed joint with cladding plate is inboard.
