Description
Technical Field
[0001] This application relates to the technical field of automotive parts, and in particular to a heated seat cushion. Background Technology
[0002] With the advancement of technology in the vehicle transportation sector, people's demands for vehicle comfort are increasing. In low-temperature environments, the interior temperature of a car parked outdoors can be extremely low. Even after the user turns on the car's air conditioning, it takes time for the interior temperature to rise, and the heat generated is very limited, not significantly affecting the car seats. Consequently, users may feel uncomfortable using car seats due to the excessively low temperature. Current methods use resistance wire heating to heat car seats, but this method has the following drawbacks: the point heating method results in uneven heating; the resistance of the resistance wire is relatively high, resulting in less heat generation at a given voltage; and the resistance wire is not flexible enough, leading to poor comfort when placed on the seat. Utility Model Content
[0003] In order to meet the heating needs of seat cushions and improve the user experience, this application provides a heated seat cushion.
[0004] The heated seat cushion provided in this application adopts the following technical solution:
[0005] A heated seat cushion includes a cover, an inner liner, a graphene sheet, a wire, and a connector. The cover has a receiving cavity, the inner liner is embedded in the receiving cavity, the graphene sheet is connected to the outer wall of the inner liner, the wire is connected to the inner liner and electrically connected to the graphene sheet, and the connector is connected to one end of the wire. The connector is used to connect to an external power source to provide power to the graphene sheet.
[0006] By adopting the above technical solution, the connector is connected to an external power source to provide power to the graphene sheet. The graphene sheet acts as a heating element, converting electrical energy into heat energy to achieve uniform heating of the entire seat cushion, which can meet the heating needs of the seat cushion. The protective cover acts as an insulator to prevent the graphene sheet from directly contacting the user, so that the temperature of the seat cushion is in a comfortable state and the user experience is improved.
[0007] Preferably, the cavity wall is provided with a strip-shaped opening, which is connected to the outside and is used for the inner lining to pass through.
[0008] By adopting the above technical solution and setting a strip-shaped opening, it is convenient to remove the liner and graphene sheet inside the receiving cavity for replacement or maintenance, thereby improving the ease of operation.
[0009] Preferably, the slot is provided with a zipper to enable the slot to be opened and closed.
[0010] By adopting the above technical solution, a zipper is provided inside the slot, which can be easily closed and opened as needed. This helps to isolate the cavity from the outside world, preventing external substances from entering the cavity and causing damage to the lining and graphene sheet, thus improving the service life of the cushion.
[0011] Preferably, it further includes a fixing component, which is embedded in the receiving cavity and connected between the liner and the sheath to achieve a fixed connection between the liner and the sheath.
[0012] By adopting the above technical solution, the inner lining and the cover are fixedly connected through the fixing components, reducing the possibility of relative movement of the inner lining during use, allowing graphene to heat the target area, improving the reliability of the cushion and the utilization rate of the heat energy generated by the graphene sheet.
[0013] Preferably, the fixing component is located on the side of the liner away from the graphene sheet, and the fixing component adopts a connecting hook and loop fastener, and a plurality of the connecting hook and loop fasteners are provided, and the plurality of the connecting hook and loop fasteners are distributed at intervals along the circumference of the liner.
[0014] By adopting the above technical solution, the fixing component is a connecting hook and loop fastener, which facilitates the assembly and disassembly of the lining and the sheath. Several connecting hook and loop fasteners are provided, and these fasteners are distributed at intervals along the circumference of the lining, thereby improving the stability of the connection between the lining and the sheath.
[0015] Preferably, it also includes a power supply bag, which is connected to the protective sleeve. One end of the power supply bag is provided with a mounting cavity for placing an external power source. The cavity wall is provided with a wire passage hole for a connector to pass through and connect to the external power source.
[0016] By adopting the above technical solution and setting up a power supply bag, the external power source can be embedded in the installation cavity, making it easy for the seat cushion and the external power source to move together. This reduces the possibility of damage to the connection between the external power source and the graphene sheet or the connection between the wire and the connector when the seat cushion is moved and the external power source remains stationary. This also improves the service life of the seat cushion.
[0017] Preferably, a sealing Velcro is attached to the cavity wall near the cavity opening to seal the cavity opening.
[0018] By adopting the above technical solution, the cavity opening is connected with a closed Velcro, which realizes the closure of the cavity opening, reduces the possibility of accidental disconnection of the external power source inside the cavity, and improves the reliability of the seat cushion.
[0019] Preferably, it also includes a protective cover, the protective cover having a groove for inserting one end of the connector to be connected to an external power source, and a connecting strip connected to the side wall of the protective cover, the other end of the connecting strip being connected to the connector.
[0020] By adopting the above technical solution, a protective cover is set up to protect the connecting joint, reducing the possibility of damage to the connecting joint caused by external objects hitting it, and improving the service life of the seat cushion.
[0021] Preferably, it also includes a control switch connected to the inner liner, the control switch being used to control the operation of the graphene sheet, and a connecting hole being provided in the cavity wall for the control switch to pass through.
[0022] By adopting the above technical solution, the control switch extends out of the receiving cavity after passing through the connecting hole, which serves as a limit for the control switch, making it convenient for users to control the graphene sheet to work and realize the opening and closing of the seat heating function.
[0023] Preferably, the liner has a cavity for filling with cushioning material.
[0024] By adopting the above technical solution, the cavity of the liner is filled with cushioning material, which improves the softness of the cushion, helps to retain the heat generated by the graphene sheet, reduces the possibility of heat loss from the side away from the human body, and improves the utilization rate of the heat generated by the graphene sheet.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. Connect the connector to an external power source to provide power to the graphene sheet. The graphene sheet acts as a heating element, converting electrical energy into heat energy to achieve uniform heating of the entire seat cushion, which can meet the heating needs of the seat cushion. The protective cover acts as an insulator to prevent the graphene sheet from directly contacting the user, so that the temperature of the seat cushion is in a comfortable state and the user experience is improved.
[0027] 2. The fastening component is a Velcro fastener, which facilitates the assembly and disassembly of the lining and the sheath. Several Velcro fasteners are provided, and they are spaced apart along the circumference of the lining to improve the stability of the connection between the lining and the sheath.
[0028] 3. A power supply pocket is provided, which can embed an external power source inside the mounting cavity. This allows the seat cushion and the external power source to move together, reducing the possibility of damage to the connection between the external power source and the graphene sheet or the connection between the power source and the connector when the seat cushion is moved and the external power source remains stationary. This extends the lifespan of the seat cushion. Attached Figure Description
