Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a vehicle seat and a vehicle. Background Technology

[0002] With the development of new energy vehicle technology, intelligent cockpit technology is becoming increasingly mature, and its functions are becoming more diverse. As a means of transportation, automobiles are increasingly providing enhanced entertainment and relaxation experiences.

[0003] The rear seats fold forward and lie flat with the trunk, providing a space where passengers can lie down and rest. This folded state of the rear seats can be called "folding into a bed".

[0004] Passengers can lie down on the suitcases and rear seats in the "bed" configuration, just like resting in their own bedroom. The comfort of the "bed" may also be an important indicator for consumers. Since the seat backs not only need to support the sitting posture but also the lying load when the passengers are in the "bed" configuration, the strength requirements are high, resulting in insufficient functionality as a bed and an overly firm experience. Utility Model Content

[0005] This application provides a vehicle seat and a vehicle that can improve the comfort of the vehicle seat in a bed-like configuration.

[0006] To achieve the above objectives, the main technical solutions adopted in this application include: In a first aspect, embodiments of this application provide a vehicle seat, including a seat and a backrest, an inflation device, an airbag, and a heating element. The backrest is hinged to the seat and can be folded toward the seat. The inflation device is disposed on the backrest. Along the thickness direction of the backrest, the airbag has a first wall and a second wall disposed opposite to each other. The first wall is connected to the backrest, and the heating element is disposed on the second wall. The inflation device is connected to the airbag to inflate or deflate the airbag.

[0007] The vehicle seat proposed in this application embodiment, by being equipped with a heating element and an airbag, provides occupants with a comfortable sleeping position while also allowing the temperature of the first wall of the airbag to be adjusted through the heating element, thus providing a comfortable experience for occupants.

[0008] Optionally, the second wall includes a second wall body and a flexible portion. Along the thickness direction of the chair back, the flexible portion is disposed on the side of the second wall body away from the first wall, and the heating portion is embedded in the flexible portion.

[0009] In the above embodiment, the flexible part is located on the side of the second wall body away from the first wall for contact with the human body. The heating part is embedded in the flexible part, and the comfort of the occupants is improved by heating the flexible part in cold weather.

[0010] Optionally, the airbag further includes a peripheral wall connected between the outer periphery of the first wall and the outer periphery of the second wall, wherein the elastic modulus of the peripheral wall is less than that of the second wall.

[0011] In the above embodiments, when the inflation device inflates the airbag, the peripheral wall with a smaller elastic modulus deforms and expands, while the second wall with a larger elastic modulus does not undergo elastic deformation or undergoes only a small elastic deformation, thereby protecting the heating part provided on the second wall from damage.

[0012] Optionally, the vehicle seat also includes a plurality of pull cords disposed on the second wall, wherein the elastic modulus of the pull cords is less than that of the second wall.

[0013] In the above embodiment, the elastic modulus of the pull cord is greater than that of the second wall, reducing the probability of pull cord breakage and enabling the pull cord to always position the airbag.

[0014] Optionally, the plurality of pull ropes includes a plurality of first pull ropes and a plurality of second pull ropes, wherein the plurality of first pull ropes extend along a first direction and are spaced apart, and the plurality of second pull ropes extend along a second direction and are spaced apart, wherein the first direction intersects the second direction.

[0015] In the above embodiments, multiple first pull ropes and multiple second pull ropes divide the second wall into multiple grids, thereby improving the positioning of the airbag and thus improving the aesthetics of the vehicle seat.

[0016] Optionally, the inflation device includes an air pump and a pipeline. The air pump is located on the back of the chair, one end of the pipeline is connected to the air pump, and the other end is connected to the internal space of the airbag.

[0017] In the above embodiment, the air pump inflates the airbag, causing it to expand in the thickness direction of the chair back. After use, when the airbag is being stored, the air pump reverses its operation to deflate the airbag, causing it to tighten.

[0018] Optionally, the vehicle seat also includes a valve located in the pipeline.

[0019] In the above embodiments, when the airbag is filled with gas, the inflation pump stops working and the valve closes to reduce the outflow of gas from the airbag; when the airbag needs to be deflated, the valve opens to allow the gas from the airbag to flow out.

[0020] Optionally, the heating element is constructed as a resistance wire embedded in the flexible element.

[0021] Optionally, the vehicle seat also includes a sensor located within the airbag for detecting the pressure within the airbag.

[0022] In the above embodiments, the sensor can detect the pressure inside the airbag. When the airbag is inflated, it can prevent the air pressure inside the airbag from becoming too high. When the airbag is deflated, it can empty the compressed gas inside the airbag and reduce the space occupied by the airbag.

[0023] Secondly, embodiments of this application provide a vehicle including the vehicle seat described in any of the above embodiments.

[0024] The vehicle in this embodiment includes the vehicle seat described in any of the above embodiments and has the beneficial effects of the vehicle seat described in any of the above embodiments. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0030] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0033] In this application, "multiple" refers to two or more (including two), similarly, "multiple sets" refers to two or more (including two sets), and "multiple pieces" refers to two or more (including two pieces).

[0034] When passengers use the vehicle with the seats in a "bed" configuration as a resting space, especially when the vehicle is in a camping area or on a highway, the current climate can directly affect the passengers' experience.

[0035] In hot weather, the car's air conditioning can be turned on to regulate the interior temperature and improve passenger comfort. However, in cold weather, although the air conditioning can be used to adjust the interior temperature, the sleeping surface, which is in direct contact with the body, affects the lying experience in cold weather. Without a heated sleeping surface, it would easily be abandoned by customers in cold environments.

[0036] Furthermore, because the seat back needs to support both sitting and reclining postures, as well as lying down when the seat is in bed position, it requires high strength, resulting in insufficient support for its bed function and an overly firm feel. Adding soft upholstery directly to the back of the seat would increase its thickness, affecting seat installation and reducing luggage space. Providing blankets or other fabric covers for passengers to use when the seat is in bed position would make packing inconvenient.

[0037] Therefore, there is a need for a vehicle seat that is comfortable enough when in bed mode and can be heated in cold weather.

[0038] Firstly, reference Figure 1 and Figure 2 This application provides a vehicle seat, which includes a seat 1 and a backrest 2, an inflation device 3, an airbag 4 and a heating element (not shown in the figure). The backrest 2 is hinged to the seat 1 and can be folded toward the seat 1. The inflation device 3 is disposed on the backrest 2. Along the thickness direction X of the backrest 2, the airbag 4 has a first wall 41 and a second wall 42 disposed opposite to each other. The first wall 41 is connected to the backrest 2, the heating element is disposed on the second wall 42, and the inflation device 3 is connected to the airbag 4 to inflate or deflate the airbag 4.

[0039] The backrest 2 is rotatable relative to the seat 1. When the backrest 2 is rotated to a predetermined position away from the seat 1, the seat 1 is used for passengers to sit on, and the backrest 2 is used for passengers to lean against. When the backrest 2 is rotated towards the seat 1 and abuts against the seat 1, the backrest 2 and the bottom wall of the suitcase can serve as a bed for passengers to lie down and rest. The airbag 4 is located on the backrest 2. The first wall 41 of the airbag 4 can be directly fixed to the backrest 2 by sewing or a fixing structure 8, or it can be prevented from sticking to the backrest 2 by Velcro 9, etc. The connection method between the airbag 4 and the backrest 2 is not limited in this application.

[0040] When the backrest 2 rotates to abut against the seat 1, the airbag 4 is above the backrest 2. The first wall 41 of the airbag 4 is connected to the backrest 2, and the heating element is located on the second wall 42. The second wall 42 of the airbag 4 is for contact with the human body. The inflation device 3 is located on the backrest 2 and is used to inflate air into the airbag 4, giving the airbag 4 a certain elasticity. After being inflated, the airbag 4 is flush with the surface of the suitcase. The airbag 4 and the surface of the suitcase together serve as a bed for passengers to lie down, improving passenger comfort. In cold weather, the heating element can be used to heat the passengers, further improving passenger comfort.

[0041] The vehicle seat proposed in this application embodiment provides a moderately firm sleeping surface for occupants by incorporating a heating element and an airbag 4. At the same time, the heating element allows for temperature adjustment of the first wall 41 of the airbag 4, providing a comfortable experience for the occupants.

[0042] For example, the heating element may be embedded in the second wall 42 or disposed on the surface of the second wall 42.

[0043] Optionally, the second wall 42 includes a second wall body and a flexible part 44. Along the thickness direction X of the chair back 2, the flexible part 44 is disposed on the side of the second wall body away from the first wall 41, and the heating part is embedded in the flexible part 44.

[0044] The flexible part 44 is located on the side of the second wall body away from the first wall 41, and is used to contact the human body to improve human comfort. The heating part is embedded in the flexible part 44, and the comfort of the occupants is improved by heating the flexible part 44 in cold weather.

[0045] For example, the flexible part 44 may be fabric or leather, etc.

[0046] Optionally, the heating element is constructed as a resistance wire embedded in the flexible part 44. The resistance wire is embedded in the flexible part 44 in an "S" shape or other form. When the resistance wire is energized, the resistance wire generates heat to heat the flexible part 44.

[0047] It should be understood that embedding the resistance wire in the flexible part 44 has a similar function to that of an electric blanket.

[0048] Optionally, refer to Figure 1 and Figure 2 The airbag 4 also includes a peripheral wall 43, which is connected between the outer periphery of the first wall 41 and the outer periphery of the second wall 42. The elastic modulus of the peripheral wall 43 is less than that of the second wall 42.

[0049] The lower elastic modulus of the peripheral wall 43 allows it to easily undergo elastic deformation under pressure, while the higher elastic modulus of the second wall 42 prevents or minimizes elastic deformation under pressure. When the inflation device 3 inflates the airbag 4, the peripheral wall 43, with its lower elastic modulus, deforms and expands first, while the second wall 42, with its higher elastic modulus, remains undeformed or undergoes only minimal elastic deformation. This protects the heating element on the second wall 42 from damage.

[0050] For example, when the seat is in the bed position, when the inflation device 3 inflates the airbag 4, the airbag 4 only inflates in the thickness direction X of the backrest 2 (that is, the vertical direction of the vehicle), and does not inflate or inflates less in the front-back direction (that is, the front-back direction of the vehicle) and the left-right direction (that is, the left-right direction of the vehicle), thereby reducing damage to the heating element.

[0051] Optionally, refer to Figure 1 and Figure 2 The vehicle seat also includes multiple pull ropes 6, which are disposed on the second wall 42. The elastic modulus of the pull ropes 6 is less than that of the second wall 42.

[0052] Multiple pull cords 6 are installed on the second wall 42. When the airbag 4 is in the inflated state, the pull cords 6 position the airbag 4, reducing the chance of the airbag 4 becoming dislodged, thereby improving the airbag 4's retractability and enhancing the aesthetics of the vehicle seat. The elastic modulus of the pull cords 6 is lower than that of the second wall 42, reducing the chance of the pull cords 6 breaking. Even if the second wall 42 deforms, the pull cords 6 will not break, ensuring that the pull cords 6 can always position the airbag 4.

[0053] The multiple pull ropes 6 can be spaced apart in one direction or staggered, depending on the specific application.

[0054] Optionally, refer to Figure 1 The plurality of pull ropes 6 include a plurality of first pull ropes 61 and a plurality of second pull ropes 62. The plurality of first pull ropes 61 extend along a first direction Y and are spaced apart, and the plurality of second pull ropes 62 extend along a second direction Z and are spaced apart. The first direction Y and the second direction Z intersect.

[0055] Multiple first pull ropes 61 are spaced apart, each extending along a first direction Y; multiple second pull ropes 62 are spaced apart, each extending along a second direction Z. It should be understood that the direction in which the multiple first pull ropes 61 are spaced apart can be determined according to the specific application.

[0056] Multiple first pull ropes 61 and multiple second pull ropes 62 divide the second wall 42 into multiple grids, thereby improving the positioning of the airbag 4 and thus improving the aesthetics of the vehicle seat.

[0057] For example, the first direction Y and the second direction Z are perpendicular, and the first pull cord 61 and the second pull cord 62 can be arranged perpendicularly. Multiple first pull cords 61 can be arranged around the airbag 4, and the second pull cords 62 can be arranged around the airbag 4. Alternatively, both ends of each first pull cord 61 are connected to the chair back 2, and the middle portion of each first pull cord 61 is connected to the second wall 42; both ends of each second pull cord 62 are connected to the chair back 2, and the middle portion of each second pull cord 62 is connected to the second wall 42.

[0058] Optionally, refer to Figure 2 The inflation device 3 includes an air pump 31 and a pipe 32. The air pump 31 is located on the backrest 2. One end of the pipe 32 is connected to the air pump 31, and the other end is connected to the internal space of the airbag 4.

[0059] An air pump 31, located on the backrest 2, can inflate or deflate the airbag 4 via a pipe 32. When the switch 5 is activated, the air pump 31 begins inflating the airbag 4, which expands along the thickness X direction of the backrest 2 until inflation is complete. After use, when the airbag 4 is being stored, the air pump 31 reverses its operation to deflate the airbag, causing the inflated airbag 4 to tighten.

[0060] The airbag 4 is provided with a vent hole connected to the pipe 32 so that the air pump 31 can inflate or deflate the airbag 4 through the pipe.

[0061] Optionally, refer to Figure 2 The vehicle seat also includes a valve 7, which is located in the pipeline 32. When the airbag 4 is inflated, the inflation pump 31 stops working, the valve 7 closes, and the outflow of gas from the airbag 4 is reduced; when the airbag 4 needs to deflate, the valve 7 opens, allowing the gas from the airbag 4 to flow out.

[0062] For example, valve 7 may be a two-way solenoid valve or a combination of a check valve and an air release valve, but this application is not limited thereto.

[0063] Optionally, the vehicle seat also includes a sensor (not shown in the figure), located inside the airbag 4, for detecting the pressure inside the airbag 4. This sensor is a pressure sensor that detects the pressure inside the airbag 4. When the air pump 31 inflates the airbag 4, the sensor detects the pressure inside the airbag 4. When the sensor detects that the pressure inside the airbag 4 reaches a predetermined value, the air pump 31 stops working, and the valve 7 closes. After use, the deflation mode of the switch 5 is activated, and the air pump 31 begins to work in reverse to deflate the airbag 4. The valve 7 opens, the gas inside the airbag 4 flows out, the inflated airbag 4 begins to contract, and the pull cord 6 begins to tighten. When the sensor detects that the vacuum level inside the airbag 4 reaches the gas evacuation requirement, the air pump 31 stops working. In other words, the sensor can detect the pressure inside the airbag 4. When the airbag 4 is inflated, it can prevent the air pressure inside the airbag 4 from becoming too high; when the airbag 4 is deflated, it can evacuate the compressed gas inside the airbag 4, reducing the space occupied by the airbag 4.

[0064] Optionally, the vehicle seat also includes a controller, which is electrically connected to the inflation device 3 and the heating unit. The controller controls the temperature by controlling the power of the heating unit. The controller can be independently integrated into the seat 1 or the seat back 2, or it can be independently installed on the vehicle body; this application is not limited to these options.

[0065] The control switch 5 in this application integrates a visual position indicator, which has the function of turning the heating on / off, and can also independently activate the inflation and deflation of the airbag 4. The position switch 5 releases a signal to the controller to control the temperature of the heating element and inflate and deflate the airbag 4. The adjustment buttons can be arranged on the seat or in other locations, and this application is not limited to these.

[0066] In one specific embodiment, a switch 5 may be provided on the seat, trunk trim, or side panel to control the heating element's on / off state. Simultaneously, this switch 5 may integrate functions for controlling the inflation and deflation of the airbag 4. The switch 5's position sends a signal to the controller, controlling the heating function of the heating element and the inflation and deflation functions of the airbag 4. The heating element's power supply is independent of the seat 1's heating power supply, allowing power to be supplied to the heating element even when the vehicle is stationary (parked).

[0067] Secondly, embodiments of this application provide a vehicle including the vehicle seat described in any of the above embodiments. The vehicle in this embodiment, including the vehicle seat described in any of the above embodiments, has the beneficial effects of the vehicle seat described in any of the above embodiments.

[0068] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0069] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.
