Abstract
The invention relates to the design of automobile interior trimming in the automobile manufacture industry and in particular relates to a middle-sized heavy-duty commercial vehicle cab heat insulation pad comprising aluminum foil, a fiber felt and non-woven fabric, wherein the fiber felt is located between the aluminum foil and the non-woven cloth, and the aluminum foil, the fiber felt and the non-woven fabric are formed through press fit; the edge and the part requiring the assembly of buckles, metal members and wiring harnesses of the heat insulation pad are provided with an assembly part; the middle part forms a sound absorption part; the thickness of the fiber felt at the assembly part is less than that at the sound absorption part; the thickness of the assembly part is less than the thickness of the sound absorption part. Compared with the prior art, the heat insulation pad is characterized in that the structure and the thickness of the conventional heat insulation pad are changed and the assembly part and the sound absorption part are provided; the thickness of the sound absorption part is greater than the thickness of the assembly part, so that sound absorption is greater; the cotton fiber felt causes no irritation to the skin of people; cotton fibers are easy to degrade and have smaller influence on environment; the whole heat insulation pad is divided into two segments which are detachably connected via buckles, thereby facilitating manual assembly.
Description
Technical field
The present invention relates to the design of automobile manufacture industry automotive trim, more particularly, to a kind of medium and heavy commercial car is driven
Sail room heat insulating mattress.
Background technology
Not only luxurious warmth with family is felt but also is pursued technology sense and shelves for the design of heavy truck interior trim in the world
Secondary sense, domestic at present high-end medium and heavy commercial car is to improve outer heat-insulated, the adiabatic effect with car, reduces in-car
Noise, improves sound-absorbing effect and lifting riding comfort and safety, and interior material selects to get over design
More to trend towards a sedan-chair type, from extensive style to environmental-friendly and comfortable attractive in appearance top grade transition, such as not only at each position
Increase heat insulating mattress, and material select more focus on heat insulation sound absorbent effect, not only lifting car load class and also can
Improve the NVH performance of car load.
The product of present invention design is used for heavy truck vehicle driver's cabin, and heat insulating mattress is located at truck cap panel beating bottom
Portion, in order to intercept heat and the noise of electromotor, prototype employ thickness all in 5mm about glass
Glass fibrous material structure, not only stimulate skin, and absorb sound, effect of heat insulation poor, the heat of bottom directly passes
Indoor to driving, new car just uses just has Customer Complaint, so upgrading is badly in need of in main engine plants.
Content of the invention
The purpose of the present invention is：A kind of medium and heavy commercial-vehicle cab heat insulating mattress is provided, the sound absorption of this heat insulating mattress,
Good heat-insulation effect, and can avoid stimulating skin, easy to assembly.For realizing this purpose, the present invention is using such as
Lower technical scheme：
A kind of medium and heavy commercial-vehicle cab heat insulating mattress, including aluminium foil, fiber felt and non-woven fabrics, fiber felt
Between aluminium foil and non-woven fabrics it is characterised in that：Described aluminium foil, fiber felt and nonwoven cloth force fit molding,
Heat insulating mattress edge and the position formation department of assembly needing assembling buckle, metalwork and wire harness, middle part is formed
Sound-absorbing part, described fiber felt is less than its thickness at sound-absorbing part, described department of assembly in the thickness at department of assembly
Thickness be less than sound-absorbing part thickness.Increased sound-absorbing part, the thickness of sound-absorbing part in the case of not affecting assembling
Degree, more than the thickness of department of assembly, increased the effect of sound-absorption and heat-insulation, and the aluminium foil of whole heat insulating mattress and non-woven fabrics
Thickness is close, and only sound-absorbing part is realized by increasing the thickness of fiber felt, convenient formation.
Further, the thickness of described sound-absorbing part is 3～4 times of department of assembly's thickness.
Further, described fiber felt is cotton fiber felt.The relatively existing glass mat of cotton fiber felt avoids
Stimulation skin, and easy degrade.
Further, assemble for ease of workman, described heat insulating mattress is split type composition, before being divided into heat insulating mattress
Section and heat insulating mattress back segment.
Further, described heat insulating mattress leading portion and heat insulating mattress back segment pass through buckle detachable connection.Buckle is torn open
Formula of unloading connects, and is easy to assemble.
Further, described aluminium foil is positioned close to the side of electromotor.Aluminium foil good heat-insulation effect, Ke Yiyou
The heat that effect isolation electromotor distributes.
Further, the thickness of described department of assembly is 4mm～6mm, and the thickness of described sound-absorbing part is 12～18mm.
Further, described heat insulating mattress is provided with pilot hole.Pilot hole is easy to heat insulating mattress and the part matching
Assembling.
Compare prior art, the device have the advantages that：
(1) present invention changes structure and the thickness of original heat insulating mattress, is provided with department of assembly and sound-absorbing part, dress
Join that portion is identical with original structure, the thickness of sound-absorbing part is more than the thickness of department of assembly, is easy to sound-absorbing.
(2) replace existing glass mat with cotton fiber felt, it is to avoid stimulation to human body skin, with
When cotton fiber degradable, the impact to environment is less.
(3) whole heat insulating mattress is divided into and being detachably connected with bayonet type between two sections, and two sections, just workman's dress
Join.
