Description
Technical field
The present invention relates to auto body accessory device, be specifically related to a kind of motor vehicle seat back vibration absorber of absorbing frequency-adjustable.
Background technology
Automotive seat often can produce strong vibration in the process of moving, and the dynamic traveling comfort of automotive seat refers to the comfort experienced after seat transfers vibrations to human body by cushion frame and seat cushion under motoring condition, main relevant with vibration characteristic.The most responsive frequency limit of human body is: vertical vibration is 4 ~ 8Hz, and horizontal direction vibration is below 2Hz, and how reducing in the vibration of this frequency limit is as much as possible main target.In order to make automotive seat, there is good dynamic traveling comfort, passive vibration isolation mode is generally adopted both at home and abroad to decay the nuisance vibration of seat, because Passive Control effectiveness in vibration suppression is generally undesirable, chaufeur is vulnerable to all types of vibratory impulse, greatly reduce the traveling comfort taken, therefore people devise various shock attenuation unit to seat vibration of decaying at present, improve travelling comfort.
Disclosed in CN 1765654A " rubber spring vibration-dampening chair ", under damping element is arranged on seat plate by it, utilize the change of different passenger size to change the rigidity of rubber spring, thus realize vibration damping, but this invention for vibration damping vertical direction being cushion, and almost can only not have attenuation to the vibration of back of seat.
And for example CN 103332128 A disclosed " vibration-damping seat for automobile ", this seat comprises base support body, the bearer connection part of the sheet being arranged at backrest support body on base support body and take for user, the bottom of bearer connection part is connected on base support body, wherein, this vibration-damping seat for automobile also comprises a shock absorber and a sliding bar, sliding bar is arranged in can slide up and down on backrest support body, and sliding bar lateral arrangement on backrest support body, the top of bearer connection part is connected on sliding bar, shock absorber to be located on base support body or backrest support body and to be had the mouth of an elastic telescopic, mouth is connected with sliding bar.Although this invention can carry out vibration damping decay to back of seat, it is still utilize the change of different passenger size to change the rigidity of damper spring, thus realizes vibration damping.But, in fact automobile is under different operating modes, the dynamic excitation frequency that seat is subject to also constantly is changing, and frequency range is wider, only utilize the conversion of driver's body weight can not the vibration that decays under most excitation frequency of actv. in the mode changing damper spring rigidity, therefore, develop and be a kind ofly applicable to various vehicle and the motor vehicle seat back vibration absorber of absorbing frequency-adjustable just seems very necessary.
Summary of the invention
The object of the present invention is to provide a kind of motor vehicle seat back vibration absorber of absorbing frequency-adjustable, it can the vibration of effective attenuation automotive seat under dynamic excitation, can adapt to the different driving cycles of automobile, the vibration of decay different frequency scope, improves the dynamic traveling comfort of seat.
The motor vehicle seat back vibration absorber of absorbing frequency-adjustable of the present invention, comprise the base plate of lateral arrangement, left adapter plate is straight up provided with at the left end of base plate, right adapter plate is straight up provided with at the right-hand member of base plate, relative chute is respectively equipped with in the inner side of described left adapter plate, right adapter plate, it is characterized in that: a mass is transversely arranged on the top of described base plate, the two ends of described mass are stretched in the chute of left adapter plate, right adapter plate respectively; Between described base plate and mass, be at least provided with a Compress Spring, described mass can slide up and down along chute and drive described Compress Spring to do fore and aft motion.
Upper end, the lower end of described left adapter plate are all connected with support with bolt, and are fixed on the left side of seat back-rest framework by support, and upper end, the lower end of described right adapter plate are all connected with support with bolt, and are fixed on the right side of seat back-rest framework by support.
The present invention has the following advantages: be installed to after on seat back-rest framework by this vibration absorber, mass in vibration absorber can slide up and down in the chute of left and right installation board, and drive Compress Spring to do fore and aft motion, the mechanical energy that dynamic excitation produces is converted to the elastic potential energy of Compress Spring, therefore, it is possible to the vibration of effective attenuation automotive seat under dynamic excitation.Under the different driving cycles of automobile, the height that mass slides up and down is different, the amplitude that Compress Spring stretches also can be different, Compress Spring stretches and causes the change of its rigidity, and then have adjusted the absorbing frequency of vibration absorber, the vibration of different frequency scope so this vibration absorber can be decayed, improves the dynamic traveling comfort of seat.In addition, the structure of this motor vehicle seat back vibration absorber and assembly technology are simply, with low cost, are suitable for heavy industrialization application.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Fig. 1 ~ Fig. 4, the motor vehicle seat back vibration absorber of described absorbing frequency-adjustable, comprise the base plate 3 of lateral arrangement, left adapter plate 5 is straight up provided with at the left end of base plate, right adapter plate 6 is straight up provided with at the right-hand member of base plate, be respectively equipped with the top that relative chute 7, mass 4 is transversely arranged on described base plate 3 in the inner side of described left adapter plate, right adapter plate, the two ends of described mass 4 are stretched in the chute 7 of left adapter plate, right adapter plate respectively; Between described base plate 3 and mass 4, be provided with two Compress Springs 2, described mass 4 can slide up and down along chute and drive described Compress Spring 2 to do fore and aft motion.
Upper end, the lower end of described left adapter plate 5 are all connected with support 8 with bolt, and the left side of seat back-rest framework 1 is fixed on by support, upper end, the lower end of described right adapter plate 6 are all connected with support 8 with bolt, and are fixed on the right side of seat back-rest framework 1 by support.
This vibration absorber is installed to after on seat back-rest framework, mass in vibration absorber can slide up and down in the chute of left and right installation board, and drive Compress Spring to do fore and aft motion, the mechanical energy that dynamic excitation produces is converted to the elastic potential energy of Compress Spring, therefore, it is possible to the vibration of effective attenuation automotive seat under dynamic excitation.Under the different driving cycles of automobile, the height that mass slides up and down is different, the amplitude that Compress Spring stretches also can be different, Compress Spring stretches and causes the change of its rigidity, and then have adjusted the absorbing frequency of whole vibration insulating system, the vibration of different frequency scope so this vibration absorber can be decayed, improves the dynamic traveling comfort of seat.
