Description

Technical Field

[0001] The present application relates to the field of vehicles, and in particular to a vehicle and a seat device. Background Art

[0002] As people's living standards continue to improve, the requirements for vehicle comfort are getting higher and higher. Passenger cars, commercial vehicles and other types of cars are basically equipped with air conditioners. The air conditioner includes a main unit, an air duct and air outlets located at multiple locations inside the cabin. The warm or cold air processed by the main unit is transported to the air outlets at different locations along the air duct.

[0003] At present, the location and size of air vents and air ducts need to take into account the layout of the entire vehicle, that is, the layout of air vents and air ducts is affected by other components of the vehicle, and the temperature parameters of local locations in the cabin may not meet the optimal comfort requirements. For example, affected by space and after-sales maintenance, the air outlets in the foot space under the seats are usually relatively small, and the air outlets are also far away from the passengers' feet, so the heat transferred to the feet of the rear passengers is relatively small. In particular, in cold environments, the heat provided by the air outlets under the seats can hardly meet the needs of heating the passengers' feet, and the comfort of the passengers is poor.

[0004] Therefore, how to meet the comfort of passengers as much as possible without increasing the difficulty of vehicle design is a technical problem that technical personnel in this field currently need to solve. Utility Model Content

[0005] The purpose of the present application is to provide a vehicle and a seat device, which can improve the foot comfort of rear passengers.

[0006] The present application provides a vehicle seat device, comprising the following components:

[0007] The seat body includes a cushion component, wherein the cushion component includes a seating surface and further includes a bottom portion capable of forming a receiving space with the floor of the vehicle;

[0008] A heating component is installed on the seat body, and the heating component is at least partially located on one side of the bottom.

[0009] In the embodiment of the present application, a heating component is provided at the bottom of the seat cushion component on the side away from the seating surface, and the heating component is at least partially located inside the accommodation space, which can be understood as a foot placement space, that is, the passenger located at the rear of the seat body can place his feet in the accommodation space. The heating component can heat the accommodation space below the seat body, and the cold air inside the accommodation space is heated to increase the temperature, thereby warming the feet of the passengers, and the location of the heating component can be closer to the feet of the passengers, which is conducive to increasing the heating speed of the feet of the passengers and improving the comfort of the passengers. At the same time, it can solve the technical problem that the bottom of the current vehicle seat body cannot be provided with a warm air outlet or the warm air outlet is far away from the feet of the passengers, making it difficult to heat the feet of the passengers located behind the seat device.

[0010] In the embodiment of the present application, the heating component at the bottom of the seat body can be used alone or in conjunction with the original warm air system. That is, a heating component is added to the seat body without changing the original warm air system layout of the current vehicle. The heating component can also heat the warm air blown out by the warm air system to further heat the warm air, thereby compensating for the slow heating and uneven distribution of the warm air after the passengers get on the vehicle. In addition, the heating component can further increase the amount of heating provided to the accommodating space, thereby meeting the heat needs of the passengers' feet in different environments and improving the overall quality and performance of the vehicle.

[0011] That is to say, in the embodiment of the present application, without changing the air duct arrangement structure, the position of the air outlet and the air outlet direction of the warm air system in the current vehicle, the defect of poor passenger comfort caused by the uneven distribution of warm air flow in the warm air system in the prior art can be solved only by installing a heating component on the seat body. For existing vehicles, the modification cost is relatively low, and the heating component is located at the bottom of the seat and basically does not occupy the space inside the vehicle, and there is no need to change the internal space layout of the cabin.

[0012] In one example, the heating component includes a flexible heating pad, and the accommodating space is located below the flexible heating pad.

[0013] In one example, the seat cushion comprises a cushion body and a cushion surface cover, wherein the cushion surface cover is at least mounted on one side of the seating surface of the cushion body, and at least a portion of the peripheral section of the flexible heating pad is connected and fixed to the cushion surface cover.

[0014] In one example, the flexible heating pad and the pad cover are connected and fixed by a sewing structure, an adhesive structure, or a hot-melt structure.

[0015] In one example, a detachable component is further included, and one end of the flexible heating pad is connected and fixed to the pad cover, and the other end is detachably connected to the pad body through the detachable component.

[0016] In one example, the pad main body includes a pad frame, a pad support body and a suspension spring, the pad support body is supported on the pad frame through the suspension spring, the seating surface of the pad main body is located on the pad support body, the pad surface cover at least covers the seating surface of the pad support body, and the flexible heating pad is detachably connected to the suspension spring through the detachable component.

[0017] In one example, an adjustable member with adjustable length is further included, and the adjustable member is disposed between the detachable component and the flexible heating pad.

[0018] In one example, the adjustable member includes at least one of a spring, a retractable cord, or an elastic cord;

[0019] Alternatively or / and, the detachable component includes a hook.

[0020] In addition, an embodiment of the present application further provides a vehicle, including:

[0021] floor;

[0022] At least two rows of seats are installed on the floor, each row of seats is arranged along the length direction of the vehicle body, at least one of the seats is a seat device of the vehicle described in any one of the above items, and the opening of the accommodating space formed by the seat device and the floor faces the rear row of seats.

[0023] In one example, a warm air system is further included, wherein the warm air system has an air outlet located in the accommodating space, and the air outlet faces toward the rear seats.

[0024] In the embodiment of the present application, the vehicle has the above-mentioned seat device, so the vehicle also has the above-mentioned technical effects of the seat device. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] Please refer to Figures 1 to 8 , Figure 1 A three-dimensional schematic diagram of a vehicle provided in an embodiment of the present application; Figure 2 This is a schematic diagram of the structure of the heating component in the embodiment of the present application; Figure 3 for Figure 1 A partial schematic diagram of the structure near the mid-foot placement space; the dotted lines in the figure represent the feet of the passengers; Figure 4 for Figure 3 A schematic diagram of the structure from another perspective; wherein the dotted lines in the figure represent the feet of the passengers; Figure 5 This is a schematic diagram of the assembly process of the cushion cover and the heating component in the embodiment of the present application; Figure 6 This is an exploded schematic diagram of the various parts of the seat cushion component 11 and the heating component in one embodiment of the present application; Figure 7 It is a partial schematic diagram of the connection position between the heating component and the suspension spring in the embodiment of the present application; Figure 8 It is a schematic diagram of the decomposition of the suspension spring and the heating component in the embodiment of the present application.

[0038] See also Figure 1The vehicle 100 provided in the embodiment of the present application includes a vehicle body 6, a floor 5 and wheels 7. The vehicle body 6 is supported by the wheels 7. The number of wheels 7 is usually four, but may be more. The vehicle body 6 has a cabin 6a. Seats are fixed inside the cabin 6a. The seats are fixed on the floor. At least two rows of seats are fixed on the floor along the length direction of the vehicle body 6. Figure 1 An example of a cockpit 6a having two rows of seats arranged in front and back is shown. For a seven-seater vehicle, three rows of seats can also be arranged on the floor 5. The number and arrangement of seats can be specifically set according to the vehicle model 100. In this application document, the side where the steering wheel is located is defined as the front, and the direction of the rear of the vehicle away from the steering wheel is defined as the rear.

[0039] In the embodiment of the present application, the structures of the seats in the cabin 6a can be the same or different. The present application provides a seat device. For a vehicle 100 with N rows of seats, there is no passenger behind the last row of seats, so there is no need to set a heating component at the bottom of the last row of seats. Therefore, the last row of seats does not need to use the seat device provided by the embodiment of the present application. Only the seats in the first row to the N-1th row can use the seat device of the embodiment of the present application. For example, for a vehicle 100 with only two rows of seats, the seat device of the embodiment of the present application can be set only in the first row, such as Figure 1 The bottom 112 of the second row seat 1 ′ is not provided with a heating component 2 ; for a vehicle 100 with three rows of seats, the first row seat and the second row seat may both be seat devices in the embodiment of the present application.

[0040] Of course, in some examples, the last row may also use the seat device provided in the embodiment of the present application.

[0041] Please refer again Figure 1In the embodiment of the present application, the vehicle 100 also includes a warm air system. In one example, the heat of the warm air system comes from the heat generated when the engine is working. After the cooling system of the engine dissipates the heat to the engine, the heat dissipated is sent into the vehicle through the fan to form warm air. Of course, for electric vehicles, the warm air system can be an air conditioning system on the vehicle 100, and the air conditioning system takes into account both cooling and heating functions. When warm air is needed, the air conditioning system turns on the heating function. The cockpit 6a can be provided with air outlets at the front window position, the driver's leg position, and the bottom 112 foot placement space of the seat body 1. In other words, the warm air system includes a front window air duct 33 connected to the air outlet at the front window position, a driver's side air duct 32 connected to the driver's leg position, and a foot air duct 31 connected to the bottom 112 foot placement space of the seat body 1. The air outlet of the front window air duct 33 can guide the warm air to the front windshield to remove the fog on the front windshield. The air outlet located at the driver's side air duct 32 can provide warm air for the driver. The air outlet 311 located at the bottom 112 of the seat body 1 can provide warm air heating for the feet of the rear passengers, that is, the warm air system in the embodiment of the present application includes the air outlet 311 located in the accommodating space 101, and the air outlet 311 is arranged to face backward, that is, the air outlet direction is toward the rear seats.

[0042] Each air outlet can be opened or closed by a controller, and when warm air is needed, the corresponding air outlet is opened. It should be understood by those skilled in the art that the location of the air outlet is not limited to the several locations described in the embodiments of the present application, and can be determined according to the specific vehicle model.

[0043] In the embodiment of the present application, the seat device includes a seat body 1 and a heating component 2. In one example, the seat body 1 may include a seat cushion component 11, a seat back 12 and a headrest 13, wherein the headrest 13 is connected to the upper part of the seat back 12, and the seat cushion component 11 is connected to the lower part of the seat back 12. The seat cushion component 11 includes a seating surface 111, and the embodiment of the present application defines the surface in contact with the buttocks of the passenger as the seating surface 111.

[0044] In the embodiment of the present application, the side of the seat cushion assembly 11 away from the seating surface 111 also has a bottom 112, and the bottom 112 and the seating surface 111 are respectively located at the lower side and the upper side of the seat cushion assembly 11. In the embodiment of the present application, the bottom 112 of the seat cushion assembly 11 can form a storage space 101 with the bottom plate of the vehicle 100, and the rear passengers can extend their feet into the storage space 101, which can also be called a foot placement space. When the seat body 1 is installed on the floor 5 of the vehicle 100, a storage space 101 is formed between the bottom 112 of the seat cushion assembly 11 and the floor 5 of the vehicle 100. For example, the feet of the second row passengers can extend into the storage space 101 below the first row seat device. That is, the feet of the Nth row passengers can extend into the storage space 101 below the N-1th row seat device.

[0045] In the embodiment of the present application, the heating component 2 is at least partially installed on one side of the bottom 112 of the seat device of the vehicle 100. The heating component 2 can be installed on the side of the bottom 112 facing the accommodating space 101. The main function of the heating component 2 is to heat the accommodating space 101. The heating component 2 can be an electric heating component, such as a heating wire heating component or a carbon fiber heating component, etc., or a heating component 2 heated by a fluid medium, such as a heating component 2 integrated with a heat dissipation pipe, and both ends of the heat dissipation pipe can be connected to an external heat source medium pipeline to pass the heat source medium into the interior of the heating component 2.

[0046] The power of the heating component 2 may be constant or adjustable, thereby increasing the flexibility of heating the accommodating space 101 .

[0047] In the embodiment of the present application, a heating component is provided at the bottom 112 of the seat cushion assembly 11 facing away from the seating surface, and the heating component is at least partially located inside the accommodating space 101. The heating component can heat the accommodating space 101 below the seat body, and the cold air inside the accommodating space 101 is heated to increase its temperature, thereby warming the feet 200 of the occupant, and the position of the heating component 2 can be closer to the feet 200 of the occupant, which is beneficial to increasing the heating speed of the feet 200 of the occupant and improving the comfort of the occupant. At the same time, it can solve the technical problem that the bottom 112 of the seat body 1 of the current vehicle 100 cannot be provided with a warm air outlet or the warm air outlet is far away from the feet 200 of the occupant, making it difficult to heat the feet 200 of the occupant located behind the seat device.

[0048] In the embodiment of the present application, the heating component 2 at the bottom 112 of the seat body 1 can be used alone or in conjunction with the original warm air system. That is, without changing the original warm air system layout of the current vehicle 100, a heating component 2 is added to the seat body 1. The heating component 2 can also heat the warm air blown out by the warm air system to further heat the warm air, thereby compensating for the slow heating and uneven distribution of the warm air after the passengers get on the vehicle. In addition, the heating component 2 can further increase the amount of heating provided to the accommodating space 101, thereby meeting the heat requirements of the feet 200 of the passengers in different environments and improving the overall quality performance of the vehicle 100.

[0049] That is to say, in the embodiment of the present application, without changing the air duct arrangement structure, the position of the air outlet and the air outlet direction of the warm air system in the current vehicle 100, the defect of poor passenger comfort caused by the uneven distribution of warm air flow in the warm air system in the prior art can be solved only by installing the heating component 2 on the seat body 1. For the existing vehicle 100, the modification cost is relatively low, and the heating component 2 is located at the bottom 112 of the seat and basically does not occupy the space inside the vehicle, and there is no need to change the internal space layout of the cabin 6a.

[0050] Please refer to Figure 2 In an embodiment of the present application, the heating component 2 may include a flexible heating pad, the shape of which can be deformed according to the installation space, and the installation flexibility is relatively high. The flexible heating pad may be a heating wire heating pad, a carbon fiber heating pad, an infrared heating pad, or the like. The flexible heating pad includes a flexible substrate 21 and a heating element 22 built into the flexible substrate 21 or fixed to the flexible substrate 21, and the heating element 22 may be sewn on the flexible substrate 21 by knitted thread. The flexible substrate 21 may be a non-woven fabric. The heating element 22 may be a heating wire or a heating tube or other components. One end of the heating wire connecting wire passes through the flexible substrate 21 to connect to the external power supply 4, which may be integrated inside the seat body 1, or may be installed on the vehicle body 6. The connecting wire 221 between the flexible heating pad and the power supply may use the internal structure of the seat as a shield.

[0051] Combination Figure 3 and Figure 4 It is understood that the flexible heating pad is installed on the side of the bottom 112 facing the foot receiving space 101, and the receiving space 101 is located below the flexible heating pad, that is, the receiving space is formed between the flexible heating pad and the floor 5 of the vehicle 100. The flexible heating pad has a simple structure, is easy to install and operate, occupies a small space, and has a low cost.

[0052] The size of the flexible heating pad can be determined according to the accommodation space 101 and the required heat. The embodiment of the present application does not disclose the size parameters and power parameters of the flexible heating pad and does not affect the understanding and implementation of the above technical solutions of the present application by those skilled in the art.

[0053] There are many ways to install the flexible heating pad, and the flexible heating pad can be fixedly connected or detachably connected to the seat body 1. For example, the connection method between the flexible heating pad and the seat body 1 includes but is not limited to the following methods: sewing, hanging, bonding, buckling, zipper or hot melting.

[0054] Please refer to Figure 5 and Figure 6 In the embodiment of the present application, the seat cushion component 11 includes a cushion body and a cushion cover 1-1. The cushion cover 1-1 is at least mounted on one side of the seating surface 111 of the cushion body. The cushion cover 1-1 may be made of materials such as ice silk, linen, cotton and linen silkworm silk, or leather. One of the functions of the cushion cover 1-1 is to improve the comfort of passengers, and the other function is to improve the quality of the vehicle interior. The cushion cover 1-1 and the cushion body can be mounted in a fully wrapped manner or a half-wrapped manner, that is, the cushion cover 1-1 wraps the seating surface 111 of the cushion body and the circumference of the cushion body. The rear end portion 23 of the flexible heating pad is connected to the cushion cover 1-1 through a sewing structure 2-1 (please refer to Figure 5 ) or adhesive structure or hot melt structure to connect and fix.

[0055] In the embodiment of the present application, at least part of the peripheral section of the flexible heating pad is connected and fixed to the cushion cover 1-1. For the seat cushion component 11, the cushion cover is made of textile material. The flexible heating pad can be connected and fixed to the cushion cover 1-1 by sewing. This connection method is relatively simple.

[0056] Please combine Figure 2 , Figures 5 to 8 It is understood that, in order to facilitate disassembly, maintenance and replacement, in the embodiment of the present application, the vehicle 100 seat device may also include a detachable component 8, and the flexible heating pad is partially detachably connected to the pad body through the detachable component 8, and partially connected and fixed to the pad cover 1-1. In this way, when it is necessary to remove the heating component 2 from the seat body 1, the flexible heating pad is separated from the pad body by operating the detachable component 8. When the pad cover 1-1 is removed from the pad body, the flexible heating pad can be separated from the pad body together with the pad cover 1-1, and it is easy to disassemble.

[0057] In a specific embodiment, the cushion body includes a cushion frame 1-4, a cushion support body 1-2 and a suspension spring 1-3, wherein the cushion frame 1-4 is mostly made of metal, for example, the cushion frame 1-4 can be formed by connecting components such as sheet metal or steel pipes, and mainly plays the role of supporting other parts of the cushion body and facilitating connection with other components. The cushion support body 1-2 mainly supports the buttocks of the passengers and can improve the comfort of the passengers, and is usually made of foam material. In other words, the sitting surface of the cushion body is located on the cushion support body 1-2, and the cushion surface cover 1-1 at least covers the sitting surface of the cushion support body 1-2. Of course, the cushion surface cover 1-1 can also cover the circumference of the cushion support body 1-2. The cushion support body 1-2 is supported on the cushion frame 1-4 by the suspension spring 1-3, and the suspension spring 1-3 is provided with a first structure connected to the cushion support body 1-2, and a second structure connected to the cushion frame 1-4. The suspension spring 1-3 mainly realizes the elastic support of the cushion support body 1-2 on the cushion frame 1-4 to improve the riding comfort. The specific structures of the pad frame 1-4, the pad support body 1-2 and the suspension spring 1-3 can be referred to the prior art and will not be elaborated in this article.

[0058] In the embodiment of the present application, the flexible heating pad is detachably connected to the suspension spring 1-3 through the detachable component 8, that is, the flexible heating pad is connected to the suspension spring 1-3. The suspension spring 1-3 itself has multiple holes or the rod is relatively thin, and the flexible heating pad can be connected to the holes or rods of the suspension spring 1-3. In this way, there is no need to additionally process a connection structure on the pad body to match the connection with the flexible heating pad, and the processing technology is relatively simple, saving processing costs.

[0059] In one example, the front end portion 24 of the flexible heating pad is connected to the suspension spring 1 - 3 via a detachable component 8 , wherein the detachable components 8 may be provided at both corners of the front end portion 24 .

[0060] In the embodiment of the present application, the seat device also includes an adjustable part 9, which is connected between the detachable part 8 and the flexible heating pad. The length of the adjustable part 9 can be adjusted, that is, by adjusting the length of the adjustable part 9, the distance between the detachable part 8 and the flexible heating pad can be adjusted. In this way, the length of the adjustable part 9 can be adjusted according to the fixed position on the suspension spring 1-3, so that the detachable part can be connected to the specified fixed position on the suspension spring 1-3, thereby improving the flexibility of the connection and fixation between the flexible heating pad and the suspension spring 1-3.

[0061] Of course, by adjusting the length of the adjustable part 9, the distance between the flexible heating pad and the foot 200 can also be adjusted, so that the flexible heating pad can have a better heating effect on the foot 200, further improving the comfort of the passengers.

[0062] In the embodiment of the present application, the adjustable part 9 can be a spring, such as a coil spring. The adjustable part 9 can also be a telescopic part, such as two parts connected by threads, and the length of the telescopic part can be adjusted by adjusting the length of the threaded connection between the two parts. Of course, the telescopic part can also be an electric telescopic part. The adjustable part 9 can also be an elastic part, such as a rope or belt made of elastic material.

[0063] One or more adjustable parts 9 may be connected between a detachable part 8 and the flexible heating pad, as long as the distance between the detachable part 8 and the flexible heating pad can be adjusted.

[0064] The two corners on the same side of the flexible heating pad can be both provided with an adjustable part 9 and a detachable part 8. Of course, the flexible heating pad can also be provided with an adjustable part 9 and a detachable part 8 in the middle of the two corners to further improve the fixing reliability of the flexible heating pad on this side. Of course, for scenarios where the flexible heating pad is relatively large in size, the two sides of the flexible heating pad perpendicular to the front-to-back direction can also be further provided with adjustable parts 9 and detachable parts 8, so that the four sides of the flexible heating pad are connected to the pad body to improve the fixing reliability of the flexible heating pad.

[0065] The embodiment of the present application also includes a temperature sensor and a controller. The temperature sensor is used to detect the temperature signal of the heating component 2. When the heating component 2 is a flexible heating pad, the temperature sensor can be built into the flexible heating pad, so that the temperature sensor does not need to occupy external space, and there is no need to set up additional installation components to install the temperature sensor.

[0066] The controller controls the heating operation of the heating component 2 according to the temperature signal detected by the temperature sensor. The controller may be a control unit of the vehicle 100, or may be a separately provided control module.

[0067] In this way, the working state of the heating component 2 can be automatically adjusted according to the needs of the passengers, so that the comfort of the passengers can reach a better state.
