Except for the special description, the materials and equipment used in the embodiments can be purchased from the market. The examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation on the present application.

[0031] In the description of the present application, it needs to be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically specified and limited.

[0032] In the description of the present application, it needs to be understood that unless otherwise explicitly specified and limited, the terms "connected", "communicated", "connected" should be understood in a broad sense, for example, it can be fixedly connected, it can be connected through an intermediate medium, it can be internal communication of two elements or interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0033] As shown in Figure 1 , Figure 2 and Figure 3 , the present embodiment provides a cushion, which comprises a cushion body, a breathable pad 2, a temperature adjusting sheet 3 and a fan 4. The cushion body has a bearing surface, which refers to the side surface of the cushion body on which the user sits when using it. The bearing surface can be a plane or an arc surface. In the present embodiment, the bearing surface is an arc surface. The cushion body is recessed inward from the bearing surface to form a sunken groove 10. The breathable pad 2 is adapted to the sunken groove 10 and is arranged in the sunken groove 10. The term "adapted" here means that the shape of the breathable pad 2 is adapted to the shape of the sunken groove 10 and the size is substantially the same, so that the breathable pad 2 can be conveniently and comfortably placed in the sunken groove 10. An installation groove 11 is arranged on the bottom wall of the sunken groove 10, and the fan 4 is arranged in the installation groove 11, while the temperature adjusting sheet 3 is arranged on the outer surface of the breathable pad 2. In the direction perpendicular to the bearing surface, the temperature adjusting sheet 3 and the fan 4 are staggered with each other. In this way, the temperature adjusting sheet 3 will not block the fan 4, and the temperature adjusting effect of the fan 4 can be avoided. It should be noted that the "direction perpendicular to the bearing surface" is a single direction when the bearing surface is a plane. When the bearing surface is an arc surface, the "direction perpendicular to the bearing surface" is different at different positions of the bearing surface.

[0034] The cushion provided in the present embodiment can be applied to a seat, which comprises a chassis and the above-mentioned cushion. The cushion is arranged on the chassis. The seat can be a gaming chair, a leisure chair, an office chair, a sofa or a passenger seat on a vehicle, etc. In other embodiments, the seat can further comprise one or more of the functional components such as a backrest, a lumbar support, a headrest, an armrest, etc. to provide more functions.

[0035] The cushion or the seat provided by the embodiment selects the fan 4 and the temperature adjusting sheet 3 as the temperature adjusting device, and through the setting of the sink groove 10 and the air permeable pad 2 on the cushion body, the fan 4 and the temperature adjusting sheet 3 can be arranged in layers and staggered with each other, so that the temperature adjusting effect of the fan 4 and the temperature adjusting sheet 3 can be fully exerted. At the same time, the air permeable pad 2 can reduce the pressure of the user on the position of the installation groove 11 on the cushion body, thereby reducing the probability of collapse of the position of the installation groove 11 on the cushion body. The specific principle is explained as follows: assuming that the air permeable pad 2 is not set, the user will directly contact the cushion body when using the seat provided with the cushion, assuming that the area of the cushion body in contact with the user is a first set area, and correspondingly, the first set area has a set area. When the scheme of setting the air permeable pad 2 in the present application is adopted, the user will directly contact the air permeable pad 2, assuming that the area of the air permeable pad 2 in contact with the user is a second set area, and under the condition that the user's weight and posture are certain, the size of the second set area is also a set area. The air permeable pad 2 has a contact area larger than the set area between the air permeable pad 2 and the cushion body, so that the air permeable pad 2 can conduct the force applied by the user to the area of the cushion body outside the first set area, compared with the scheme without the air permeable pad, the force on the first set area of the cushion body can be reduced, thereby reducing the pressure of the user on the position of the installation groove 11 on the cushion body. In addition, the power of the fan 4 and the temperature adjusting sheet 3 is relatively low, and the energy consumption is very low during use, and the external power bank can also be used for a long time.

[0036] Specifically, in the embodiment, the fan 4 is a cooling fan, that is, the fan 4 can play a role of refrigeration and cooling; the temperature adjusting sheet 3 is an electric heating sheet, that is, the temperature adjusting sheet 3 can play a role of heating and warming. It should be pointed out that in other alternative embodiments, the fan can also be a hot air fan with built-in electric heating wire, that is, the fan can also play a role of heating and warming, and correspondingly, the temperature adjusting sheet can also be a refrigeration sheet, for example, a common semiconductor refrigeration sheet, that is, the temperature adjusting sheet can also play a role of refrigeration and cooling.

[0037] In addition, in the embodiment, the air permeable pad 2 is made of polyester silk and mesh cloth, which is a cloth pad with a certain thickness and air permeability, of course, other fabrics can also be used to make the air permeable pad 2. And in other alternative embodiments, the air permeable pad 2 can also be made of bamboo, plastic and other rigid materials, and air permeable holes are formed thereon. As described above, the shape and size of the air permeable pad 2 can be manufactured according to the shape and size of the sink groove 10, so that the air permeable pad 2 can be conveniently and comfortably placed in the sink groove 10.

[0038] In order to obtain better temperature adjustment effect, the temperature adjustment sheet 3 and the fan 4 are arranged as follows from the perspective of ergonomics: the bottom wall of the sink 10 is provided with a plurality of installation grooves 11 at the middle region thereof from front to back, the air permeable pad 2 is provided with the temperature adjustment sheet 3 on both sides thereof, and the temperature adjustment sheet 3 extends along the front-back direction of the air permeable pad 2. Herein, "front", "back", "left" and "right" refer to the direction of the user's face when the user sits on the cushion, i.e., the direction of the user's face is "front", the direction of the user's back is "back", and the left and right sides of the user are "left" and "right" respectively.

[0039] Specifically, the temperature adjustment sheet 3 in the embodiment is provided with two pieces, the installation groove 11 is provided with two, and each installation groove 11 is provided with a fan 4. As shown in Figure 1 and Figure 3 , the two temperature adjustment sheets 3 and the two fans 4 are arranged in a cross shape. It should be noted that in other alternative embodiments, other arrangements can also be used, for example, the installation groove 11 is arranged at the four corners of the bottom wall of the sink 10, and the temperature adjustment sheet is arranged at the middle of the air permeable pad 2.

[0040] As shown in Figure 3 and Figure 4 , the cushion body in the embodiment includes a support frame 5 and a cushion cotton 1 arranged on the support frame 5, and the cushion cotton 1 forms a bearing surface. The cushion cotton 1 in the embodiment is a shaped cotton with good resilience, and the sink 10 and the installation groove 11 are arranged thereon. As described above, by designing the sink 10 and arranging the air permeable pad 2 in the sink 10, the air permeable pad 2 can be used to reduce the pressure of the user on the installation groove 11 of the cushion cotton 1, i.e., the air permeable pad 2 can play a certain supporting role to prevent the installation groove 11 arranged on the cushion cotton 1 from collapsing due to excessive local stress. Further, as shown in Figure 5 , the support frame 5 in the embodiment includes a bottom frame and a support plate 53 arranged on the bottom frame, and the side surface of the cushion cotton 1 away from the bearing surface forms a fitting portion 12 corresponding to the sink 10, and the support plate 53 is tightly attached to the fitting portion 12 to form support for the fan 4 located in the installation groove 11. The support frame 5 in the embodiment is made of carbon steel, and the support frame 5 is tightly attached to the fitting portion 12 on the cushion cotton 1 to form support for the cushion cotton 1, and indirectly forms support for the fan 4 located in the sink 10 through the bottom wall of the sink 10.

[0041] It should be noted that, since the fan 4 is installed in the installation groove 11, in order to ensure normal air flow, the bottom wall of the installation groove 11 and the support plate 53 are provided with air inlet holes penetrating through. Specifically, the bottom wall of the installation groove 11 is provided with a first air inlet hole 103, and the support plate 53 is provided with a second air inlet hole 530. The first air inlet hole 103 is aligned with and communicates with the second air inlet hole 530. When the fan 4 is working, the rotation of the fan blade drives the air to flow from the bottom of the cushion to the side of the bearing surface of the cushion.

[0042] In the embodiment, the fan 4 and the temperature adjusting sheet 3 both have power supply cables leading outwards. Correspondingly, the bottom wall of the sink groove 10 and the support plate 53 are provided with wire holes penetrating through. Specifically, the bottom wall of the sink groove 10 is provided with a first wire hole 100, and the support plate 53 is provided with a second wire hole 531. The first wire hole 100 corresponds in position to the second wire hole 531 and communicates with the second wire hole 531. The bottom wall of the sink groove 10 is further provided with a first wire groove 101 between the first wire hole 100 and the installation groove 11. The power supply cable of the fan 4 enters the first wire hole 100 through the first wire groove 101, and then leads outwards of the support frame 5 through the first wire hole 100 and the second wire hole 531. There is a gap between the air-permeable pad 2 and the side wall of the sink groove 10 for the cable to pass through. The bottom wall of the sink groove 10 is further provided with a second wire groove 102 between the gap and the installation groove 11. The power supply cable of the temperature adjusting sheet 3 enters the first wire groove 101 through the gap, and then enters the first wire hole 100 through the first wire groove 101. Then, the power supply cable leads outwards of the support frame 5 through the first wire hole 100 and the second wire hole 531.

[0043] It should be noted that the cushion provided in the embodiment further comprises a control unit. The control unit is connected to the fan 4 and the temperature adjusting sheet 3, and is used to control the fan 4 and the temperature adjusting sheet 3 to work. Specifically, the control unit comprises a key switch 6. The key switch 6 is electrically connected to the fan 4 and the temperature adjusting sheet 3 respectively. The key switch 6 comprises a fan 4 switch assembly, a heating sheet switch assembly and a connecting cable. The fan 4 switch assembly and the heating sheet switch assembly both comprise corresponding electric control boards and keys. The key switch 6 is electrically connected to the power supply cables leading out of the wire holes through the connecting cable. In this way, the fan 4 and the temperature adjusting sheet 3 can be controlled to work through the key switch 6. In other alternative embodiments, the control unit can also adopt other schemes, which will be described in detail later.

[0044] In combination Figure 4 and Figure 5As shown in the drawings, the cushion cotton 1 in the embodiment is stably connected with the support frame 5 by the following scheme: the bottom frame in the support frame 5 comprises a frame body 50, a surrounding barrier 51 arranged at the side of the frame body 50, and a connecting rod 52 arranged at the middle of the frame body 50, and a support plate 53 is fixed on the connecting rod 52. The cushion cotton 1 is formed with a limiting flange 13 matched with the frame body 50 and a slot 14 matched with the surrounding barrier 51, the limiting flange 13 is arranged around the frame body 50 and is attached to the frame body 50, and the surrounding barrier 51 is inserted into the slot 14. The limiting flange 13 formed on the cushion cotton 1 cooperates with the frame body 50 to limit the cushion cotton 1, preventing the cushion cotton 1 from being separated from the support frame 5, and the insertion of the surrounding barrier 51 into the slot 14 further improves the limiting effect. The frame body 50 can have a rectangular structure, and can also have other shapes. Further, the cushion provided in the embodiment further comprises an elastic cushion cover (not shown in the drawings), the elastic cushion cover is sleeved on the cushion cotton 1, and the elastic cushion cover makes the cushion cotton 1 tightly attached to the support frame 5 through elastic deformation. That is, the elastic force of the elastic cushion cover can make the cushion cotton 1 and the support frame 5 have a greater attachment force, so that the cushion cotton 1 is less likely to be separated from the support frame 5. In addition, a steel wire is arranged at the edge of the elastic cushion cover, and a steel wire is also pre-buried at the corresponding position of the cushion cotton 1, after the elastic cushion cover is sleeved on the cushion cotton 1, the steel wires arranged on the two are buckled together by a C-shaped ring to realize the positioning of the elastic cushion cover relative to the cushion cotton 1. In other embodiments, the C-shaped ring can be other connecting pieces capable of fixedly connecting the steel wire on the cushion cover and the steel wire on the cushion cotton together.

[0045] The aforementioned key switch 6 can be sewn on the elastic cushion cover, and the connecting cable of the key switch 6 can be led out to the bottom of the support frame 5 through the side of the cushion cotton 1.

[0046] When designing the shape and size, first, the shape and size of the cushion cotton 1 are designed according to the needs, and then the shape and size of the support frame 5, the breathable pad 2 and the elastic cushion cover are designed according to the shape and size of the cushion cotton 1. The number and specifications of the fans 4 and the temperature adjusting sheets 3 can be selected according to the needs, and the number of the corresponding mounting grooves 11 can be designed according to the number of the fans 4. The cushion has a simple structure, and the shape and size are not obviously different from common cushions.

[0047] In the assembly, the fan 4 is first placed in the mounting groove 11, and the bottom wall and the side wall of the mounting groove 11 limit the fan 4, then the air-permeable pad 2 is placed in the sink groove 10, and the temperature adjusting sheet 3 is attached to the air-permeable pad 2. In the above assembly process, the power cable of the fan 4 and the temperature adjusting sheet 3 is led out to the first wire hole 100 in the above-mentioned manner. Then the support frame 5 is assembled with the cushion cotton 1. Specifically, the power cable is passed through the second wire hole 531 on the support plate 53, and the enclosure 51 on the support frame 5 is inserted into the insertion slot 14 on the cushion cotton 1, and at the same time, the limiting flange 13 on the cushion cotton 1 is arranged outside the frame 50. Finally, the elastic cushion cover with the key switch 6 sewn is sleeved on the cushion cotton 1.

[0048] The seat with the cushion can be provided with a battery or externally connected to a power source. In use, the fan 4 and the temperature adjusting sheet 3 are controlled to work by operating the key switch 6, and then blowing and cooling or heating are realized. In order to improve the user experience, the key switch 6 in the embodiment has a multi-position function (as can be easily understood, different positions correspond to different cooling or heating effects), and an indicator is also provided, for example, different colors or different numbers are used to indicate the position switching. The specific example is as follows: press the cooling key in the key switch 6 once, start the three-position blowing of the fan 4, and light up three green indicator lights; press the cooling key again, switch to two-position blowing, and light up two green indicator lights; press the cooling key again, switch to one-position blowing, and light up one green indicator light. Similarly, press the heating key in the key switch 6 once, start the three-position heating of the temperature adjusting sheet 3, and light up three red indicator lights; press the heating key again, switch to two-position heating, and light up two red indicator lights; press the heating key again, switch to one-position heating, and light up one red indicator light.

[0049] When the key switch 6 controls the fan 4 and the temperature adjusting sheet 3 to work, the controller can be matched, the input end of the controller is electrically connected with the output end of the key switch 6, and the output end of the controller is electrically connected with the fan 4 and the temperature adjusting sheet 3 to realize, the controller receives the trigger signal generated by the pressing times of the key switch 6, and controls the position of the fan 4 or the temperature adjusting sheet 3 based on the trigger signal.

[0050] In other embodiments, the key switch 6 can also be a knob. The knob can have two, one of which is used for air volume adjustment, and the other is used for heat adjustment. The knob is directly connected between the power source and the fan 4, and the other knob is directly connected between the power source and the temperature adjusting sheet 3. The resistance value of the voltage dividing resistor is adjusted by rotating the knob, so as to adjust the air volume of the fan 4 or the heat of the temperature adjusting sheet 3.

[0051] As described above, the present embodiment proposes a scheme of using the key switch as the control unit, in other optional embodiments, the control unit can also use other schemes. For example, the key switch as the control unit in the present embodiment is sewn on the elastic cushion cover, in other schemes, the control unit can also be designed as a remote controller and a control module controlled by the remote controller by using the existing signal control mode, the control module is electrically connected with the fan and the temperature adjusting sheet, and then the remote controller can be used to control the fan and the temperature adjusting sheet to work through the control module.

[0052] Alternatively, in another optional embodiment, the control unit can include a detection sensor, the detection sensor controls the fan and the temperature adjusting sheet to work according to the detected external information. For example, the detection sensor can include a pressure sensor, the pressure sensor is arranged in the bearing surface area of the cushion cotton, so that whether the user sits on the cushion can be judged according to the pressure sensor. The pressure sensor can be used in cooperation with the key switch described above, for example, after the user sits on the cushion, the user can operate the key switch to adjust the temperature by himself, when the user leaves, the key switch can be used to control the fan or the temperature adjusting sheet which has been started to be closed, or the pressure sensor can be used to detect that the user leaves and directly control the fan or the temperature adjusting sheet to be closed (the user may forget to close the operation). The detection sensor can also include a temperature sensor, the pressure sensor and the temperature sensor are used in cooperation to realize completely automatic temperature adjustment. For example, when the pressure sensor detects that the user sits on the cushion, whether to start the fan or the temperature adjusting sheet to adjust the temperature is decided according to the ambient temperature detected by the temperature sensor, when the pressure sensor detects that the user leaves, the fan or the temperature adjusting sheet which has been started is controlled to be closed.

[0053] It should be noted that the detection sensor needs to be used in cooperation with the controller when in use, that is, the detection sensor sends the collected external information (such as the pressure information or the ambient temperature information described above) to the controller, the controller compares the external information with the preset value, and then controls the fan or / and the temperature adjusting sheet to work according to the comparison result.

[0054] Finally, it should be noted that: the above embodiments are only optional embodiments of the present application, and cannot be used to limit the scope of protection of the present application, any non-substantial changes and replacements made by the person skilled in the art on the basis of the present application all belong to the scope of protection required by the present application.
