[0031] The first embodiment of the present application provides a vehicle. It should be noted that the vehicle in the present application may refer to a large car, a small car, a special-purpose car, etc. For example, according to the vehicle type, the vehicle in the present application may be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV) or other vehicle types. Generally, a vehicle is provided with wheels, a power source, and a transmission system arranged between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, so that the wheels rotate, thereby driving the vehicle to travel.
[0032] It should be noted that in the embodiments of the present application, the type of the power source of the vehicle is not limited. For example, for a fuel vehicle, the power source may refer to a fuel engine such as a gasoline engine or a diesel engine; for an electric vehicle, the power source may refer to an electric motor; for a hybrid vehicle, the power source may refer to an engine or an electric motor; for a vehicle powered by other means, the power source may refer to a device that generates power.
[0033] It should be noted that vehicles are generally provided with seats in the vehicle, wherein the number of seats provided in the vehicle varies according to different types of vehicles. For example, for a sedan, the number of seats in the vehicle may be 4; for an off-road vehicle, the number of seats in the vehicle may be 5 to 7; for a multi-purpose vehicle, the number of seats in the vehicle may be 7; for other vehicle types, the number of seats in the vehicle may be set as required, and in the embodiments of the present application, the number of seats in the vehicle is not limited.
[0034] The vehicle provided by the first embodiment of the present application refers to Figure 1 In addition to the above-mentioned vehicle seat, it also includes a vehicle headrest 1. The headrest component 11 of the vehicle headrest 1 is connected to the top of the vehicle seat to provide head support for the user, thereby reducing the user's fatigue caused by lack of head support during driving.
[0035] Based on the first embodiment, the present application proposes a second embodiment. Figure 1 In order to solve the problem that users of different heights have different adaptability requirements for the head shape surface supported by the vehicle headrest 1, the embodiment of the present application also provides a vehicle headrest 1, including a headrest assembly 11, a headrest cover 12 and an inflatable assembly 13; the headrest assembly 11 has a supporting surface; the headrest cover 12 is mounted on the outside of the headrest assembly 11; the inflatable assembly 13 is arranged in the lower area of the supporting surface and is used for inflation to drive the lower side of the headrest cover 12 to expand outward and provide flexible support.
[0036] The vehicle headrest 1 provided in the embodiment of the present application can be inflated by the inflatable component 13, so that the lower side of the headrest cover 12 expands outward, thereby providing flexible support for the user's head; the shape of the headrest cover 12 can be adjusted by adjusting the inflation amount, thereby providing different support and wrapping effects for the heads of users of different heights, and achieving adaptation of the head shape surface for users of different heights. In addition, since the inflatable component 13 is arranged between the headrest cover 12 and the headrest component 11, it can be avoided that the inflatable component 13 is exposed and easily damaged; and since the user touches the headrest cover 12 located on the outer layer when touching the entire vehicle headrest 1, the transition between the upper part of the headrest and the inflated protruding lower part of the headrest is smoother, without any abnormal convex feeling, thereby improving the user's comfort level.
[0037] Based on the second embodiment, the present application proposes a third embodiment. Figure 1 and Figure 2In order to solve the problem of how to make the expansion direction of the airbag mainly expand outward perpendicular to the support surface, in this embodiment, the inflatable component 13 includes at least two airbags 131, and the at least two airbags 131 are stacked along a first path, and the first path is perpendicular to the support surface.
[0038] In this embodiment, during the expansion process, two or more airbags 131 expand in different directions respectively, but since at least two airbags 131 are stacked in sequence along the first path, when the multiple airbags 131 are stacked together, their overall expansion in the direction perpendicular to the support surface is most significant, that is, along the first path direction. Since one of the main functions of the vehicle headrest 1 is to provide suitable head support adaptation for users of different heights, and to achieve adaptation, the lower part of the vehicle headrest 1 needs to expand outwards so that the lower part of the vehicle headrest 1 protrudes from the upper part of the vehicle headrest 1, thereby providing support for the upper part of the user's head and the lower part of the back of the head. Therefore, when the airbag 131 expands along the first path, it can not only achieve a larger range of adjustment of the protrusion amount of the vehicle headrest 1 with a smaller inflation amount, but also avoid the problem that the protrusion effect of the airbag 131 along the first path is weakened due to the expansion of the airbag 131 in other directions, thereby weakening the support effect provided for the lower part of the back of the user's head.
[0039] Further, in some embodiments of the present application, referring to Figure 1 and Figure 2 In order to solve the problem of how to make the stacked airbags 131 fit better under the back of the human head after inflation, in the fourth embodiment of the present application, the inflatable component 13 includes N airbags 131, and the serial numbers of the N airbags 131 increase successively in the direction away from the support surface; the first airbag 131 is connected to the lower area of the support surface, the k+1th airbag 131 is connected to the lower side of the kth airbag 131, and the height dimension of the k+1th airbag 131 is smaller than the height dimension of the kth airbag 131; wherein, 1≤k≤N-1.
[0040] In the present embodiment, since the k+1th airbag 131 among the multiple airbags 131 is connected to the lower side of the kth airbag 131, and the height dimension of the k+1th airbag 131 is smaller than the height dimension of the kth airbag 131, the multiple airbags 131 can form an inclined surface inclined downward along a first path when inflated, and the inclined surface coincides with the arc below the back of the human body. Therefore, when the user leans against the vehicle-mounted headrest 1, the headrest cover 12 inflated along the inclined surface can better fit under the back of the user's head, thereby improving the adaptability of the vehicle-mounted headrest 1 to the head shape of users of different heights.
[0041] Further, in some embodiments of the present application, referring to Figure 1 and Figure 2, the inner cavities of at least two airbags 131 are interconnected, and one of the airbags 131 is provided with an inflation port 1311; the inflation assembly 13 also includes an air pipe 132, one end of the air pipe 132 is connected to the inflation port 1311, and the other end of the air pipe 132 is used to connect to the air supply device. In this way, in this embodiment, the airbags 131 are interconnected, and the air pipe 132 is connected to one of the airbags 131, so that gas can be introduced into multiple airbags 131 through a single air pipe 132 to inflate them, without using multiple air pipes 132 to be connected to each airbag 131 one by one.
[0042] In this embodiment, an air supply device is used to inflate the airbag 131. It should be noted that this embodiment does not limit the type of air supply device and the inflation method. Exemplarily, the air supply device can be an external air supply device or a vehicle-mounted air supply device; the air supply device can be an automatic suction device such as an electric air pump, a compressed air tank, a manual air pump, a foot-operated air pump, or other types of air supply devices with inflation methods.
[0043] Based on the second embodiment, the present application proposes a fourth embodiment. In order to solve the problem of how to make the vehicle headrest 1 provide flexible support for the head when the inflatable component 13 of the vehicle headrest 1 is not inflated, refer to Figure 1 and Figure 3 The headrest assembly 11 includes a flexible support 111 having a first side surface, the inflatable assembly 13 is arranged on the lower side of the first side surface, and the headrest cover 12 is sleeved on the outside of the flexible support 111 .
[0044] Thus, in this embodiment, the headrest assembly 11 includes a flexible support 111. When the inflatable assembly 13 is not inflated, the flexible support 111 provides flexible support for the entire head; after the inflatable assembly 13 is inflated, the flexible support 111 provides support for the upper side of the back of the head, and the inflatable assembly 13 provides flexible support for the lower side of the back of the head, thereby achieving head shape support for users in different situations and improving the comfort of users leaning on the vehicle headrest 1.
[0045] It should be noted that this embodiment does not limit the type of the flexible support 111. Exemplarily, the flexible support 111 can be set as a headrest foam, such as polyurethane foam, or a fiber filler, such as polyester fiber, polyester fiber, etc. The above materials can provide a soft touch and a certain degree of support.
[0046] Further, in some embodiments of the present application, referring to Figure 1The flexible support 111 has a second side surface, which is arranged opposite to the first side surface; the headrest assembly 11 includes a headrest frame 112, which is connected to the second side surface, and the headrest frame 112 is used to connect to the seat in the vehicle. Thus, in this embodiment, the flexible support 111 is fixed by connecting the headrest frame 112 to the seat in the vehicle and connecting the headrest frame 112 to the second side surface of the flexible support 111.
[0047] Specifically, in some embodiments of the present application, refer to Figure 1 The top of the headrest frame 112 is provided with a connecting structure, which is in the shape of a plate, and a plurality of connecting holes are opened on one side of the connecting structure, through which the threaded fasteners pass through the connecting holes and are threadedly connected to the second side surface of the flexible support 111. In this way, the connecting structure can not only realize the connection between the headrest frame 112 and the flexible support 111, but also because the connecting structure is in the shape of a plate, compared with the solution of directly connecting the headrest frame 112 and the flexible support 111 and providing support, the contact area of the connecting structure with the flexible support 111 is increased, thereby providing more reliable support and fixation for the second side surface of the flexible support 111.
[0048] Furthermore, in some embodiments of the present application, if there is no rigid structure to provide protection for the outer periphery of the trachea 132, it is easy to be scratched or blocked, making it difficult to inflate normally. Figure 4 To solve the above problems, the headrest frame 112 has a cavity inside; the inflatable component 13 includes an airbag 131 and an air tube 132. The airbag 131 is provided with an inflating port 1311. One end of the air tube 132 is connected to the inflating port 1311, and the other end of the air tube 132 passes through the inner cavity of the headrest frame 112 and is used to connect to the air supply device. In this way, in this embodiment, the air tube 132 passes through the headrest frame 112, and the rigid structure of the headrest frame 112 is used to provide protection for the air tube 132, avoiding problems such as the air tube 132 being blocked or scratched, and ensuring the reliability of inflation and deflation.
[0049] Further, in some embodiments of the present application, since the airbag 131 and the air tube 132 are arranged on the first side of the flexible support 111, and the headrest frame 112 is arranged on the second side of the flexible support 111, in order to solve the problem of how to avoid the air tube 132 from being blocked on the path leading to the headrest frame 112, refer to Figure 3The flexible support 111 is provided with a connecting channel 1111, the connecting channel 1111 extends from the first side surface to the second side surface, and the air pipe 132 is arranged in the connecting channel 1111. Thus, in this embodiment, by providing the connecting channel 1111 on the flexible support 111, and allowing the air pipe 132 to pass through the connecting channel 1111 and then be arranged in the headrest frame 112, it is avoided that the air pipe 132 is squeezed and blocked on the path leading to the headrest frame 112, resulting in the situation that the gas cannot be normally charged and discharged.
[0050] Based on the second embodiment, the present application proposes a fifth embodiment. Since the headrest assembly 11 is provided with an inflatable assembly 13, even when it is not inflated, the existence of the inflatable assembly 13 will cause the headrest cover 12 to bulge, resulting in a decrease in the user's comfort when the inflatable assembly 13 is not inflated. In order to solve the above problem, refer to Figure 1 and Figure 3 The headrest assembly 11 is provided with a mounting groove 113, which is located at the lower side of the support surface and is used to accommodate the inflatable assembly 13. Thus, in this embodiment, by accommodating the inflatable assembly 13 in the mounting groove 113, it is prevented that the inflatable assembly 13 protrudes from the support surface of the headrest assembly 11 in the uninflated state, thereby ensuring a good experience for the user to lean against the vehicle-mounted headrest 1 in the uninflated state. In the inflated state, the inflatable assembly 13 expands outward and protrudes from the support surface, and drives the lower side of the headrest cover 12 to expand outward to provide flexible support.
[0051] The serial numbers of the embodiments of the present application are only for description and do not represent the advantages and disadvantages of the embodiments. The above are only preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
