Including elastic back cushion layer 21, squab plate layer 22, insulating press boards layer 23, piezoelectric vibrator layer 24 and insulation inner panel layer 25, the back cushion
Several springs 26 are connected between plate layer 22 and insulating press boards layer 23, the piezoelectric vibrator layer 24 is electrically connected with accumulator (figure
In do not show), the top and bottom of the backrest body 2 are respectively equipped with by dorsal plate 3, described vertical by dorsal plate 3
Direction is equipped with through-hole compatible with subway carriage montant handrail 1 (by through-hole so that together by dorsal plate 3 and backrest body 2
It is sheathed on handrail 1, is not marked in through-hole figure), it is described to be equipped with several charging interfaces 4, the charging by dorsal plate 3
Interface 4 is electrically connected with accumulator.
It can be seen from figure 1 that the backrest body 2 includes two symmetrical hollow secondary halfbodies, two times halfbody is integrated
It forms hollow cylindrical backrest body 2, two symmetrical hollow secondary halfbodies is respectively aligned to subway carriage montant when use
1 split of handrail, which is integrated, to be sheathed on backrest body 2 on subway carriage montant handrail 1.Two halfbodies are using routine
Connection type is integrated, and no longer repeats one by one herein.
Secondary halfbody can be the regular geometric configuration such as half tetragonal body, half polyhedron, semicylinder, time halfbody in the present embodiment
It is set as semicylinder, two hollow semicylinders are integrated to form hollow cylinder backrest body 2 (as shown in Figure 1, set
Big hollow cylinder outside handrail 1 is the backrest body), the whole each face all stress equalizations of such backrest, more
Facilitate passenger to lean on, while for the backrest of cylindrical structure is compared to polyhedral backrest, without corner angle, passenger is avoided to touch
It is injured.
It can be seen from figure 1 that being set to the top and bottom of backrest body by dorsal plate 3, it is sheathed on subway together with backrest body 2
On compartment montant handrail 1, therefore, in order to unified, it is also configured as hollow cylindrical structure by dorsal plate 3 in the present embodiment, by two
(the small hollow cylindrical structure set on 2 top of hollow cylinder backrest body is for a symmetrical hollow semicylinder composition
It is described to lean on dorsal plate 3).
Such as Fig. 1 and Fig. 2 as it can be seen that the entire length of the squab plate layer 22 is longer than the entire length of elastic back cushion layer 21, lean on
The upper and lower ends of raft 22 grow elastic back cushion layer 21 part be equipped with buffer rubber gasket 5 (buffer rubber gasket 5 be in circular ring shape
Formula is sleeved on the upper and lower ends of squab plate layer 22).Meanwhile the top and bottom that backrest body 2 is set to by 3 convex of dorsal plate
Portion, and buffer rubber gasket 5 is wrapped, to buffer squab plate layer 22 and the active force between dorsal plate 3.
The piezoelectric vibrator layer 24 is made of several piezoelectric vibrators, is connected by conductor in parallel between each piezoelectric vibrator, should
Commercially available Conventional piezoelectric oscillator may be used in piezoelectric vibrator, and piezoelectric vibrator is by piezoelectric ceramics and elastic metallic described in the present embodiment
Material is bonded together composition, the power generation for ensureing piezoelectric vibrator layer 24 simultaneously, improve the elasticity of piezoelectric vibrator layer 24.
Several springs 26 are uniformly distributed between squab plate layer 22 and insulating press boards layer 23, and insulating press boards layer 23 passes through bullet
Spring 26 is connected with squab plate layer 22, and the quantity of spring 26 is adjusted according to actual use demand, usually no less than 2.
Several hooks 6 are equipped with by dorsal plate 3 set on 2 bottom of backrest body, some articles can be hung on by passenger
On hook 6, reduce the heavy burdens, while in order to avoid 6 hooks of hook hinder passenger, linking up with 6 gib head and being inwardly arranged, link up with 6 quantity according to
Actual use demand is adjusted, usually no less than 2.
In addition, the elastic back cushion layer 21 in backrest body 2 is removably sheathed on the outer surface of squab plate layer 22, work as elasticity
When being worn by bed course 21, it is conveniently replaceable repair.
Also, rectification amplifier can be electrically connected between piezoelectric vibrator layer 24 and accumulator (not indicate in figure
Come), it is transmitted in accumulator and stores after the electric energy rectification that piezoelectric vibrator layer 24 generates is amplified, rectification amplifier and electric power storage
As soon as it has been a more mature technology that pond, which is electrically connected, no longer repeat one by one herein.
Power generation backrest described in the utility model when in use, be directly sleeved on subway carriage montant handrail can (in order to
Backrest fixing sleeve can be further set on handrail by fixedly connected parts such as screws by fixed backrest and handrail), when passenger does not have
When having seat to transfer to rest on by back, for backrest is compared to handrail, forced area significantly increases, while the outermost layer of backrest
For elastic back cushion layer 21, pliability is preferable, and comfort level when passenger leans on is good；Meanwhile passenger rests on the elastic back cushion of backrest
On layer 21, active force is applied to backrest, which first passes through elastic back cushion layer 21 and be transmitted on squab plate layer 22, and then transmits
Onto spring 26,26 stress of spring deforms, and applies elastic force to the insulating press boards layer 23 being attached thereto, insulating press boards layer 23 exists
Piezoelectric vibrator layer 24 is squeezed under the action of elastic force, piezoelectric vibrator layer 24 produces electricl energy under the action of extruding, so i.e.
The mechanical energy generated when can lean on backrest passenger is converted into electric energy, and the electric energy of generation, which is transferred in accumulator, to be stored,
The electric connection of accumulator and charging interface 4 (can be USB interface, or other custom interfaces), when passenger use it is small
When type electric appliance such as mobile phone etc. needs charging, compact electric apparatus can be inserted into charging interface 4 and charged, making for passenger will not be delayed
With further improving the psychological comfort degree of passenger.
In conclusion power generation backrest provided by the utility model, simple in structure, easy to use, it is suitable for subway carriage
Montant handrail, for not having the passenger at seat dependence in subway, the comfort level of dependence is good, and can passenger be leaned on generation
Mechanical energy is converted into electric energy, can be that passenger powers without external power supply, clean environment firendly is energy saving, highly practical.
It is last it is necessarily pointed out that：The foregoing is merely the preferable specific implementation modes of the utility model, but this
The protection domain of utility model is not limited thereto, and any one skilled in the art discloses in the utility model
