Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology, and in particular relates to an adaptive seat applied to automobiles. Background Technology

[0002] A car seat is the seat you sit on while riding in a car. Based on the parts, they can be roughly divided into: front seats: headrest, backrest, seat cushion, (armrest); rear seats: (headrest), backrest, seat cushion, side bolsters, (armrest).

[0003] Currently, most hybrid, gasoline, and pure electric vehicles on the market have simple seat structures, and their shapes can only be designed with reference to standard body types to provide relatively supportive seat contours. They cannot provide a comfortable seat support for all body types. Therefore, this utility model proposes an adaptive seat for automobiles to solve the above problems. Utility Model Content

[0004] This invention provides an adaptive seat for automobiles, aiming to solve the problems mentioned in the background art.

[0005] This utility model is implemented as follows: an adaptive seat for automobiles includes a power supply, dual air pumps, an air tank, a seat cushion pressure sensor, a backrest pressure sensor, a valve body, and pneumatic equipment.

[0006] The pneumatic device includes a pneumatic lumbar support, pneumatic side wings, and a seat cushion air bag;

[0007] The power input current drives the dual air pumps, which are used to inflate the air tank and supply air to the pneumatic device when the air pressure is insufficient. The valve body is used to monitor whether the gas in the air tank is saturated. The valve body is also used for gas transmission between the air tank and the pneumatic device. The valve body is controlled by the seat pressure sensor and the backrest pressure sensor. The seat pressure sensor and the backrest pressure sensor adjust the contact area between the human body and the seat pressure sensor and the backrest pressure sensor by inflating and deflating the pneumatic device to achieve adaptive fit to the human body. The backrest pressure sensor inflates the pneumatic side wings in the pressure area when the human body turns or leaves the seat to compensate for the pressure and restore the human body's normal driving posture.

[0008] Preferably, the valve body is connected between the dual air pump and the air storage tank. When the valve body detects that the gas in the air storage tank is not saturated, the dual air pump is activated to fill the air storage tank.

[0009] Preferably, the valve body is connected between the gas storage tank and the pneumatic device, and the valve body controls the gas storage tank to charge and release gas into the pneumatic device.

[0010] Preferably, when the seat cushion pressure sensor and the backrest pressure sensor are simultaneously contacted, the seating area is determined to be a person, and the adaptive seat is activated; when the seat cushion pressure sensor and the backrest pressure sensor are not simultaneously contacted, the seating area is determined to be an object, and the adaptive seat is not activated.

[0011] Preferably, the seat pressure sensor and the backrest pressure sensor control the valve body to inflate or deflate the pneumatic device to adjust the fit of the support contour between the seat and the human body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The adaptive seat determines the fit between the seat and the human body by measuring the contact area between the seat cushion pressure sensor and the backrest pressure sensor. This means the seat's support contour conforms to the body's contours. Pneumatic devices are controlled to increase the contact area, ensuring a better fit for different body types and providing adequate support. Dual air pumps and an air tank ensure rapid air supply, allowing the adaptive function to quickly provide support. During cornering, the seat coordinates with pneumatic side wings to support the occupant and help them regain a driving posture by detecting a sudden increase in the contact area of ​​the backrest pressure sensor. This addresses the problems of current seats not conforming to all body types, slow adaptive function implementation, and inability to maintain a stable driving posture. Attached Figure Description

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0019] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0020] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figures 1 to 4This utility model provides a technical solution: an adaptive seat for automobiles, which can be installed in the middle or front row of the car interior. It includes a power supply, dual air pumps, an air tank, a seat cushion pressure sensor, a backrest pressure sensor, a valve body, and pneumatic equipment. The pneumatic equipment includes a pneumatic lumbar support, pneumatic side wings, and a seat cushion air bag. The power supply drives the dual air pumps with input current. When the dual air pumps are working, they output gas to inflate the air tank and simultaneously supply air to the pneumatic equipment when the air pressure is insufficient. The valve body monitors whether the gas in the air tank is saturated. If saturated, it controls the dual air pumps to stop working; if not saturated, it controls the dual air pumps to inflate the air tank. The valve body also serves as a gas transfer mechanism between the air tank and the pneumatic lumbar support, pneumatic side wings, and seat cushion air bag. The valve body is connected to the seat cushion pressure sensor and the backrest. The system is controlled by pressure sensors. When both the seat cushion pressure sensor and the backrest pressure sensor are in contact with an object, it is determined that a person is sitting. At this time, the control valve opens the inflation valve to supply air to the pneumatic lumbar support, pneumatic side wings, and seat cushion air bag, causing them to inflate. This pushes the seat cushion pressure sensor and backrest pressure sensor to continuously conform to the human body. Once the seat cushion pressure sensor and backrest pressure sensor reach the standard contact area with the human body, the valve closes, and the seat contour provides adequate support for the human body. When the car is turning or the human body deviates from the correct driving posture, the contact area of ​​the pressure sensor on one side of the backrest increases. At this time, the valve is quickly activated to inflate the pneumatic side wings of the backrest in the area with increased contact area, providing reverse support force and quickly assisting the driver to return to the correct position.

[0024] Among them, the dual air pump is used to fill the air tank and supply air to the pneumatic equipment when the air pressure is insufficient. The dual air pump and the air tank provide efficient and rapid air supply to the pneumatic equipment.

[0025] The valve body can monitor whether the gas content in the gas tank is saturated and determine whether to start the dual air pump to replenish the gas in the gas tank. When the valve body detects that the gas in the gas tank is not saturated, the dual air pump starts to fill the gas tank; otherwise, no gas is replenished.

[0026] The backrest pressure sensor and the seat cushion pressure sensor determine whether the seating area is a person or an object by whether they are simultaneously contacted, and then determine whether to activate the adaptive seat. When the seat cushion pressure sensor and the backrest pressure sensor are simultaneously contacted, the seating area is determined to be a person, and the adaptive seat is activated. When the seat cushion pressure sensor and the backrest pressure sensor are not simultaneously contacted, the seating area is determined to be an object, and the adaptive seat is not activated.

[0027] The seat cushion pressure sensor and backrest pressure sensor increase or decrease the fit between the seat contour and the human body by inflating or deflating the pneumatic device to achieve the optimal support contour.

[0028] The backrest pressure sensor can detect which side has a sudden increase in pressure contact area when turning and inflate the corresponding side pneumatic wing to provide support for the human body, thus helping the human body return to the correct driving posture.

[0029] In this invention, efficient air supply is achieved through dual air pumps and an air tank, improving the responsiveness of the pneumatic equipment. The presence of a person or object in the seating area is determined by whether the seat cushion pressure sensor and backrest pressure sensor are simultaneously in contact, effectively preventing accidental activation of the adaptive function. The contact area between the seat cushion pressure sensor, backrest pressure sensor, and the human body determines whether the pneumatic equipment should be activated to conform to the body and provide support, thus providing conformal support for different body types. The inflation and deflation of the pneumatic equipment achieves the effect of conforming to different body types. The backrest pressure sensor determines whether the human body has deviated from the normal driving posture, thereby inflating the pneumatic wings in the pressure area to correct the driving posture and assist the passenger in returning to the correct sitting position.

[0030] The working principle and usage process of this utility model are as follows: When the power is on, the dual air pumps are activated to inflate the air tank. When the air tank is saturated, the feedback valve closes and the dual air pumps stop inflating. When the backrest pressure sensor and the seat cushion pressure sensor of the car seat are in contact with the human body at the same time, the valve is activated to inflate the pneumatic side wings, pneumatic lumbar support, and seat cushion air bag. The pneumatic equipment pushes the backrest pressure sensor and the seat cushion pressure sensor to increase the contact area between them and the human body, so as to achieve the purpose of adaptive fit and support. When the backrest pressure sensor suddenly increases the contact pressure on one side, the valve is activated to inflate the pneumatic side wings of the pressurized area to achieve counter-compensation and assist the human body to return to the correct driving posture. This utility model adopts the above-mentioned structure, which is simple and reliable, has complete functions, and is suitable for different human body shapes.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
