Description
Technical field
The utility model relates to a kind of sound-insulating structures, more specifically, the utility model, which relates generally to one kind, can be used for vehicle
Carry the sound-insulating structure of inflator pump.
Background technique
Currently, vehicle-mounted air pump structure on the market is essentially identical, it is by motor band piston in piston cylinder
Interior reciprocating motion, and air inlet and compression are completed by air inlet in cylinder body and the check valve on gas outlet, and then carry out to tire
Inflation hinders noise transmission, but poor effect due in the vehicle-mounted inflator pump of this class formation, only relying on shell, while noise exists
Enclosure interior roundtrip generates resonance, can amplify noise, thus it is necessary to for the sound-insulating structure of existing vehicle-mounted inflator pump into
Row research and improvement.
Utility model content
One of the purpose of this utility model is to provide a kind of sound insulation knot that can be used for vehicle-mounted inflator pump in view of the above deficiencies
Structure solves vehicle-mounted inflator pump in the prior art with expectation and relies solely on shell obstruction noise transmission, and soundproof effect is poor, and noise exists
Enclosure interior roundtrip, generating resonance leads to the technical problems such as decibels amplification.
In order to solve the above technical problems, the utility model uses following technical scheme:
A kind of sound-insulating structure can be used for vehicle-mounted inflator pump provided by the utility model, including outer housing, the shell
The inside of body is equipped with motor, and output end and the piston rod of the motor are connected by power, and the end of the piston rod is equipped with work
Chock plug, the piston rod and piston head are placed in cylinder body, and the inside of the outer housing is additionally provided with multiple acoustical cottons, the sound-absorbing
Cotton is placed in the side of motor, cylinder body.
Preferably, further technical solution is: the outer housing is equipped with multiple openings, and each opening is corresponding
Outer housing inside be mounted on an acoustical cotton.
Further technical solution is: the outer housing is equipped at least one exhaust outlet, and the exhaust outlet is corresponding
One acoustical cotton is installed inside outer housing.
Compared with prior art, the beneficial effects of the utility model first is that: it is multiple by adding within the outer shell
Acoustical cotton, and acoustical cotton surrounds the intracorporal noise source of shell, can as noise source motor and piston/cylinder make a noise
When, noise is absorbed first, i.e., interior energy is converted for noise during noise transmission by acoustical cotton, to reduce noise
Decibels, be effectively improved sound when vehicle-mounted inflator pump uses, help to promote user experience, while the knot of the utility model
Structure is simple, and suitable for installing and using in the inside of all kinds of vehicle-mounted inflator pumps, application range is wide.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for illustrating the utility model one embodiment；
In figure, 1 it is outer housing, 2 is motor, 3 is cylinder body, 4 is acoustical cotton, 5 is exhaust outlet.
Specific embodiment
The utility model is further elaborated with reference to the accompanying drawing.
Refering to what is shown in Fig. 1, one embodiment of the utility model is a kind of sound-insulating structure that can be used for vehicle-mounted inflator pump, packet
Outer housing 1 is included, the inside of the outer housing 1 is equipped with motor 2, and output end and the piston rod of the motor 2 are connected by power, and corresponding
, the end of the piston rod is equipped with piston head, and piston rod and piston head are both needed to be placed in the cylinder body 3 of piston, even more important
It is to be additionally provided with multiple acoustical cottons 4 in the inside of outer housing 1, these acoustical cottons 4 are both needed to be placed in the side of motor 2, cylinder body 3.
In the present embodiment, by adding multiple acoustical cottons 4 in the inside of outer housing 1, and acoustical cotton 4 will be in outer housing 1
Noise source surround, can as noise source motor 2 and piston/cylinder 3 make a noise when, noise is absorbed first, i.e.,
Interior energy is converted by noise during noise transmission by acoustical cotton 4, to reduce the decibels of noise, is effectively improved vehicle-mounted fill
Sound when air pump uses helps to promote user experience.
In another embodiment of the utility model, inventor in order to advanced optimize the attraction effect of above-mentioned acoustical cotton 4,
After considering internal transmission to external position of the noise from outer housing 1, the physical location of acoustical cotton 4 is adjusted,
Specially when multiple openings are arranged on outer housing 1, one is mounted on inside the corresponding outer housing 1 of each opening
Acoustical cotton 4；And it is further, especially when exhaust outlet 5 is arranged on outer housing 1, then with greater need for corresponding outer in the exhaust outlet 5
One acoustical cotton 4 is installed inside shell 1.
Refering to what is shown in Fig. 1, the above-mentioned preferred one embodiment of the utility model is in actual use, when above-mentioned sound insulation knot
Structure, in use, after the power supply conducting of inflation pump motor 2, starts to drive piston rod and piston head in cylinder body 3 in vehicle-mounted inflator pump
Inside move back and forth, in the process, different degrees of vibration can occur for cylinder body 3 and motor 2, and then generate noise, this
When, the sound wave that the two vibration generates is contacted with acoustical cotton 4 first, as mentioned here above, will be in noise transmission by acoustical cotton 4
Interior energy is converted by noise in the process, noise is sponged, prevents noise leakage, to realize low noise, make vehicle-mounted inflator pump work
Noise when making greatly reduces, and in the sound-insulating structure in application, without changing the structure inside vehicle-mounted inflator pump, Yi Jiqi
The sealing performance of outer housing 1 only installs corresponding acoustical cotton 4 in reserved space inside it.
