Description

Technical Field

[0001] This application relates to the field of automotive seat technology, specifically to a seat frame with air storage function and a vehicle seat. Background Technology

[0002] In the research and design of car seats, pneumatic units are increasingly used to achieve certain special functions. At the same time, in order to cooperate with the normal operation of the pneumatic unit, a separate air supply device is required to supply air to the pneumatic unit. However, due to the limited space available inside the seat, there is not enough space to place the existing air tank.

[0003] Therefore, the limited storage space inside car seats restricts further research and development of car seats and creates technical obstacles to the realization of some functions. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, this application aims to provide a seat frame and vehicle seat with air storage function to solve the above problems.

[0005] According to the first aspect of this application, a seat frame with a gas storage function is provided within the seat frame, the storage space being used to store gas.

[0006] The seat frame is provided with at least one ventilation channel, which is connected to the storage space. An air source delivers gas to the storage space through the ventilation channel, or the storage space supplies gas to the air-using device inside the seat through the ventilation channel.

[0007] The seat frame provided by this utility model has a gas storage function, which can store gas and supply gas to the gas-using device inside the seat. This utility model utilizes the space inside the seat frame to store gas without occupying the limited space in other areas inside the seat, thus realizing the gas supply to the gas-using device and providing strong support for the development of some functions of the seat.

[0008] Specifically, the seat frame is equipped with interconnected ventilation channels and storage spaces. Designers can first supply gas to the storage space through the ventilation channels, and then supply the gas in the storage space to the gas-using device through the ventilation channels according to the needs of the gas-using device. The storage space can be used multiple times, providing designers with sufficient gas storage locations and solving the current difficulty of not being able to install additional gas tanks in car seats due to limited space.

[0009] In some embodiments of the seat frame with air storage function of this utility model, part or all of the space inside the seat frame is configured as the storage space.

[0010] The seat frame comprises multiple hollow tubing sections, one or more of which can be configured as storage spaces to store gas and supply gas to gas-using devices.

[0011] Designers can set the size of the storage space according to actual needs. When a smaller storage space is needed, one or more tubes can be selected as the storage space. When a larger storage space is needed, all the storage spaces in all the tubes in the seat frame can be used to store gas.

[0012] Designers can also design seat frames with larger storage space, which can improve the seat frame's ability to store gas, as well as increase the strength and rigidity of the seat frame, making the entire seat more sturdy.

[0013] In some embodiments of the seat frame with air storage function of this utility model, the seat frame with air storage function further includes a sealing component, which is disposed at the interface of the ventilation channel and the interface of the storage space, and the ventilation channel and the storage space together form a sealed space.

[0014] When the storage space inside the seat frame is used to store gas, a sealing component can be installed to construct a sealed space, which can store gas for a long time and reduce gas leakage within the storage space. The sealing component can be installed at the interface of the ventilation channel or at the interface of the storage space. Whether gas is being delivered to the storage space or to the gas-using device through the ventilation pipe, gas leakage can be reduced and the utilization rate of the gas in the storage space can be improved.

[0015] In some embodiments of the air-storage seat frame of this utility model, the seat frame includes a backrest frame part, a seat frame part, and a connecting part, wherein the backrest frame part and the seat frame part are connected as one unit through the connecting part.

[0016] The storage space is provided within the backrest frame portion and / or the seating frame portion and / or the connecting portion.

[0017] The seat frame is divided into a backrest frame, a seat frame, and a connecting part. Each part can be set with independent storage space, which makes it easy to supply gas to gas devices in different areas independently.

[0018] Two or three of the parts can be connected to form a through cavity, which supplies gas to multiple gas-using devices, thereby increasing the gas capacity of the through cavity and reducing the frequency of gas delivery into the through cavity.

[0019] In some embodiments of the seat frame with air storage function of this utility model, the backrest frame, the seat frame and the connecting part are tubular frames or sheet metal frames.

[0020] Using a tubular frame allows the hollow structure inside the tubing to serve as storage space, improving the space utilization of the seat frame. Using a sheet metal frame allows multiple sheets to be constructed into a single storage space, which is used to house the air storage unit. The sheet metal frame forms the outer shell of the air storage unit, reducing the air storage unit's susceptibility to interference from the external environment.

[0021] In some embodiments of the seat frame with air storage function of this utility model, the storage space is provided with a flexible air storage unit. The flexible air storage unit has an elastic structure, is used to store pressurized gas, and can supply gas to the gas-using device at a stable pressure.

[0022] A flexible gas storage unit is installed inside the seat frame. The elastic expansion of the flexible gas storage unit can accommodate more gas and can also appropriately increase the gas pressure. In particular, when the flexible gas storage unit supplies gas to the gas-using device, the elastic contraction of the flexible gas storage unit can stabilize the output gas and control the output gas within a predetermined pressure range to meet the needs of the gas-using device.

[0023] In some embodiments of the seat frame with air storage function of this utility model, the seat frame with air storage function further includes an air pressure sensor, which is disposed in the flexible air storage unit and is used to detect the air pressure in the flexible air storage unit; or, the air pressure sensor is disposed in the storage space and is used to detect the air pressure in the storage space.

[0024] By setting up a pressure sensor, the pressure in the storage space is detected. Based on the detected pressure value, it is determined whether the gas capacity in the storage space meets the needs of the gas-using device, and then it is determined whether gas needs to be supplied to the storage space. Based on the detected pressure value, it can also be determined whether the storage space meets the preset storage capacity, thereby determining whether there is a leak or damage in the storage space. Based on the detected pressure value, it can also be determined whether the gas in the storage space can provide the preset gas volume or pressure required for the normal operation of the gas-using device.

[0025] In some embodiments of the seat frame with air storage function of this utility model, the seat frame part is provided with a double-layer structure, and a storage compartment is formed between the double-layer structure. The storage compartment is used to store air or to accommodate an air storage device.

[0026] By designing the seating frame as a double-layer structure with a storage compartment, the internal space of the seating area of ​​the seat assembly can be utilized to the maximum extent. Gas can be stored in part or all of the space in the storage compartment. In particular, when a flexible gas storage unit is used in the storage compartment, the irregular space in the storage compartment can be made reasonable use, thereby improving the space utilization rate within the seat frame.

[0027] A second aspect of this utility model provides a vehicle seat, the vehicle seat comprising a seat frame with an air storage function as described in any of the preceding claims.

[0028] When a seat frame with air storage function as described above is used in the vehicle seat, the limited space inside the seat frame is used to store gas and supply gas to the gas-using device, which improves the space utilization rate of the seat frame. When the gas in the storage space can meet the needs of the gas-using device, there is no need to set up an additional air tank, which provides greater technical support for R&D personnel and designers, and allows more pneumatic functional components to be arranged in the seat assembly.

[0029] In some embodiments of the vehicle seat of this utility model, the vehicle seat includes a connecting pipe, the connecting pipe having a hollow structure, and part or all of the space within the connecting pipe being configured as the storage space.

[0030] Additional connecting pipes are installed on the vehicle seat to provide storage space and increase the total amount of gas stored. These connecting pipes can be part of the seat frame or connected to the seat frame as an external structural component.

[0031] In some embodiments of the seat frame of this utility model, the vehicle seat is provided with a pneumatic system, and the gas in the storage space is used to supply air to the pneumatic system.

[0032] The pneumatic system on vehicle seats includes pneumatic massage devices, pneumatically adjustable seat cushions, occupant grading detection devices, pneumatic lumbar supports, or pneumatic leg supports, etc. Attached Figure Description
