DETAILED DESCRIPTION

[0022] Implementations of the present disclosure will now be described, by way of embodiments only, with reference to the drawings. It should be understood that the specific embodiments described here are only used to explain but not to limit the present application. Based on the embodiments in the present application, all other embodiments obtained by one ordinary skill in the art without creative labor is within the scope of the present application.

[0023] The invention is further explained below in combination with the attached drawings and the embodiment.

[0024] Referring to FIG. 1-3, FIG. 1 is a structural diagram of a preferred embodiment of a switchable mode gravity-sensing heated seat cushion; FIG. 2 is a schematic side view of the switch shown in FIG. 1; FIG. 3 is control block diagram of switchable mode gravity-sensing heated seat cushion.

[0025] A switchable mode gravity-sensing heated seat cushion, which comprise:

[0026] Seat cushion cover 1 and switch 2, The switch 2 is provided on the seat cushion cover 1. The switch 2 is provided with on/off button 3. The switch 2 is provided with a temperature adjustment button 4;

[0027] The gravity-sensing heating plate 5 is arranged inside the seat cushion cover 1, and a pressure thin film 6 is provided inside the seat cushion cover 1. The pressure thin film 6 is located at the bottom of the gravity-sensing heating plate 5. The interior of the seat cushion cover 1 is filled with filler 7.

[0028] The position of switch 2 is not limited to a certain place on the seat cushion cover 1. It can be set at any position on the seat cushion cover 1.

[0029] The filler 7 is preferably filled with cotton. It should be noted that it is not necessarily cotton. It may be an inflatable cushion or other various fillings.

[0030] The temperature adjustment button 4 can control the gravity-sensing heating plate 5, so that the seat cushion can achieve the effect of manual control of heating. When the on/off button 3 is pressed, the manual mode can be adjusted to the automatic mode. After a person sits on it, press the pressure thin film 6, the gravity-sensing heating plate 5 can be heated. When the person leaves, the pressure thin film 6 cannot feel the pressure, and it enters a non-heating state.

[0031] The gravity-sensing heating plate 5 provides three different temperature gears, which can be switched through the temperature adjustment button 4.

[0032] The thickness of the pressure thin film 6 is <=0.65 mm, response point: 80 g, durability: >1 million times, initial resistance: >10 m (no load), working voltage: 0V-20V, working current: 0-50 mA, response time: <1 ms, recovery time: <15 ms, working temperature: 20 C.-60 C. The port type is a hot melt joint or equivalent material capable of completing heating and The startup parameter is 80 G.

[0033] The light assembly 8 is provided on the top of the switch 2. The light assembly 8 includes a white light 81 and a temperature light 82. The white light 81 and the temperature light 82 are both installed on the top of the switch 2.

[0034] The bottom of the switch 2 is provided with a power interface 9, wherein the power interface 9 has a wire, and the power interface 9 is used to connect to an external power supply to realize the power supply function, the power interfaces not limited to USB interfaces, type C, DC and other interfaces.

[0035] The shape of the seat cushion cover 1 is one of square, rectangle, circle, and triangle. The shape of the seat cushion cover 1 not limited to square, rectangle, circle, triangle, and can be in any shape.

[0036] The exterior of the seat cushion cover 1 is provided with a waterproof coating.

[0037] The working principle of the switchable mode gravity induction heating seat cushion provided by this invention is as follows:

[0038] The setting of switch 2 is used to turn on and switch modes. The initial state is manual mode. Press the on/off button 3 to switch from manual mode to automatic mode. In manual mode: white light 81 does not light up, and temperature light 82 lights up. At this time, press the temperature adjustment button 4 to adjust the three temperature settings of low, middle and high, and start using the heated seat cushion; automatic mode: in the standby state, the white light 81 is on, and the temperature light 82 is off. At this time, the seat cushion is in a pressure-free state, and the three settings of low, middle and high are adjusted. Temperature, select the gear, and the pressure switch is triggered when the person sits on it. At this time, the temperature light 82 lights up, and the temperature is the corresponding gear temperature. The heated seat cushion is started to be used. In the automatic mode, the person leaves the seat cushion, that is, there is no pressure on the seat cushion. Finally, the temperature lamp 82 goes out after a short period of time, and then enters the non-heating state.

[0039] Compared with the related techniques, a switchable mode gravity-sensing heated seat cushion provided by the present invention have the following beneficial effects:

[0040] The seat cushion heating is started through gravity induction. As soon as a person sits on it, the pressure switch is triggered, and the seat cushion begins to heat. When the person leaves the seat cushion, that is, after there is no pressure on the seat cushion, it enters a non-heating state. This can avoid manual forgetting to turn it off, avoid power loss, and can to switch between manual adjustment and automatic induction adjustment, the manual and automatic modes are distinguished through the change of the indicator light assembly 8 on the switch 2, thereby making it more convenient to use the seat cushion.

[0041] In another embodiment of the disclosure, The switchable mode gravity-sensing heated seat cushion also include a backrest, which contains a foldable heating pad integrated with the pressure thin film 6 of the gravity-sensing heating plate 5.

[0042] The above descriptions are only examples of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly used in other applications Relevant technical fields are similarly included in the scope of patent protection of the present invention.
