Massage type ventilation seat for automobile
Technical Field
The invention relates to the field of automobile accessories, in particular to an automobile seat.
Background
For the car seat, its travelling comfort is very exquisite, especially in summer, because ambient temperature is higher, when the human body is sat on the car, often the back has more sweat, and the air conditioning of in-car air conditioner can't reach between back and the seat, leads to sweat to ferment in this region, has obvious vexation sense, lets the people very uncomfortable, arouses bedsore easily when sedating for a long time. Therefore, there is a ventilation seat cushion (of course, it can also be made into a seat) for an automobile, in which a ventilation channel is provided, the ventilation channel is connected to a blower, when the blower is working, the blower can blow out airflow from the air holes on the surface of the seat cushion through the ventilation channel, so as to achieve the effect of ventilation; in order to improve the comfort of the seat cushion, the seat cushion is generally provided with a massage function; the massage function is realized through a magnetic therapy module, a far infrared module or a movable mechanical structure; the magnetic therapy module and the far infrared module are weak in action, the comfort level is very limited due to the fact that no obvious meridian mechanical action exists, the magnetic therapy module and the far infrared module are achieved through a vibrating machine or a movable massage head, the comfort level is very limited or even poor for the vibrating machine massage structure, a complex transmission mechanism is needed for the movable massage head, the realization cost is huge, and the movable massage head is easy to damage.
Disclosure of Invention
In view of the above problems, an object of the present invention is to provide a massage-type ventilation seat, which can achieve ventilation and massage functions at the same time, and has a simple structure and low cost.
The technical scheme adopted by the invention for solving the technical problems is as follows: the massage type ventilation chair comprises a chair back and a chair seat, wherein the upper side and the lower side of the chair back comprise a pair of rotating shafts, and a conveying belt type annular air bag is arranged on each rotating shaft; the annular air bag is made of non-breathable elastic fabric, a transverse air hole belt formed by air hole arrays is arranged on the surface of the annular air bag facing the back of a human body, and a flexible screen plate which is connected with the chair back and has a smooth surface is arranged in front of the surface facing the back of the human body; the pair of rotating shafts are driven by a stepping motor which continuously and alternately rotates forwards and backwards; the surface of the chair back, which is contacted with the annular air bag, is smooth; the seat is provided with an air bag, and the upper surface of the air bag is provided with an air hole; the annular air bag and the air bag are connected to an air pump through an air duct.
Preferably, the flexible mesh plate is also made of elastic materials, so that the swelling position of the annular air bag can be pushed to the back of a human body, and the back of the human body can feel a flowing air cushion feeling along with the movement of the swelling position of the annular air bag, thereby further promoting the comfort level.
The invention has the beneficial effects that: when the massage type ventilation seat is used, the annular air bag is stretched and tied on the pair of rotating shafts which continuously and alternately rotate forwards and backwards, so that the transverse air hole belts on the annular air bag can reciprocate up and down, and air flow which is flushed to the back of a human body from the transverse air hole belts can scrape and rub the back up and down like a scraper blade, so that a massage effect with high comfort is generated, and ventilation are realized; the massage type ventilation seat can realize the functions of ventilation and massage at the same time, and has simple structure and lower cost.

Detailed Description
The invention is further illustrated with reference to the following figures and examples:
in the embodiment shown in fig. 1, the massage-type ventilated seat comprises a chair back 11 and a chair seat 12, wherein the upper side and the lower side of the chair back 11 comprise a pair of rotating shafts 2 and 2 ', and a conveyer-type annular air bag 3 is stretched on the rotating shafts 2 and 2'; the annular air bag 3 is made of non-breathable elastic fabric, a transverse air hole belt 30 formed by air hole arrays is arranged on the surface of the annular air bag 3 facing the back of a human body, and a flexible screen plate 5 which is connected with a chair back and has a smooth surface is arranged in front of the surface facing the back of the human body; the pair of rotating shafts 2 and 2' are driven by a stepping motor (not shown) which continuously and alternately rotates forwards and backwards; the stepping motor can only drive one of the rotating shafts, and the other rotating shaft is used as a driven shaft and driven by the annular air bag 3.
The surface of the chair back 11, which is contacted with the annular air bag 3, is smooth; the seat 12 is provided with an air bag 4, and the upper surface of the air bag 4 is provided with an air hole 40; the annular gas bag 3 and the gas bag 4 are connected to an air pump (not shown) via a vent line.
In the ventilated seat, the flexible mesh 5 is also made of an elastic material, so that the bulge of the annular air bag 3, which is formed on the surface far away from the transverse air hole belt 30 due to the air pressure in the annular air bag 3, can be pressed against the back of the human body. Along with the up-and-down movement of the annular air bag 3, the transverse air hole belt 30 also moves up and down, so that the bulging position of the annular air bag 3 also moves up and down, the human body can feel the flowing air cushion feeling on the back, and the comfort is further promoted.
When the massage type ventilation seat is used, the annular air bag 3 is connected on the pair of rotating shafts 2 and 2' which continuously and alternately rotate forwards and backwards, so that the transverse air hole belt 30 on the annular air bag 3 can reciprocate up and down, and the air flow rushing to the back of a human body from the transverse air hole belt 30 can scrape and knead the back up and down like a scraper, so that a massage effect with high comfort is generated, and ventilation are realized; the massage type ventilation seat can realize the functions of ventilation and massage at the same time, and has simple structure and lower cost.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
