[0046] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "install", "connect", "connect", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.
[0047] The seat elements and seats disclosed in the embodiments of the present application take the seats of cars as an example. However, it can be understood that the seats of the present application are applicable to vehicles other than cars, such as airplanes, cruise ships and other vehicles. Moreover, the seats of the present application are not limited to vehicles, such as seats in fixed places, such as seats for audience seats in large-scale events and conferences. As long as there are front and rear seats, the seat structure of the present application can be applied to provide good visual perception and audio-visual experience for the passengers in the back row.
[0048] refer to Figures 1 to 5 As shown, in some embodiments, the seat 100 may include a backrest portion 1 and a headrest portion 2 , wherein the headrest portion 2 is located on the top of the backrest portion 1 .
[0049] The meaning of the backrest portion 1 here is similar to that in the field of seats, that is, the seat mainly provides a back support function for the occupant, and the headrest portion 2 is arranged corresponding to the head of the occupant.
[0050] like Figure 1 or Figure 5 As shown, the headrest portion 2 includes a headrest body 21, which provides support for the head of the occupant. The structure connecting the headrest portion 2 and the backrest portion 1 can be as follows: Figure 1 The structure shown in the figure is connected by the headrest rod 22, and can also be as follows Figure 5 The headrest body 21 shown is directly connected to the backrest portion 1 in a relatively slidable manner, for example, via a structure such as a slide rail, but this is not intended to be limiting.
[0051] Continue to refer Figures 1 to 5 As shown, the headrest portion 2 is provided with an ultra-short-throw projection element 3 , and the ultra-short-throw projection direction is toward the backrest 1 , and the projection image projected by the ultra-short-throw projection element 3 is displayed on the backrest 1 .
[0052] For the structure using the headrest rod 22, the wiring harness connected to the ultra-short-throw projection element 3 is located inside the headrest rod 22, and the wiring harness is respectively connected to the power supply and the projection image signal input source. The structure set in this way is compact, but it is not limited to this. For example, the connection method between the ultra-short-throw projection element 3 and the projection image signal input source can also be through a wireless connection method such as Bluetooth, WiFi, 5G, etc., or it can be through a wireless connection to obtain the projection image signal input source from the cloud.
[0053] For the heat dissipation of the ultra-short-throw projection element 3, in some embodiments, a heat dissipation fan and heat dissipation holes may be provided inside the headrest portion 2 for heat dissipation of the ultra-short-throw projection element 3. This is particularly applicable to a headrest having a structure in which a fan is integrated inside the headrest portion 2 to provide functions such as fragrance.
[0054] The ultra-short-throw projection here can also be called ultra-close-range projection, and its meaning is similar to that in the field of projection, that is, the projection device has a parameter of projection ratio, which is the ratio of the projection distance to the length of the bottom edge of the projected picture. The formula is: projection ratio = projection distance / screen width. The smaller the ratio, the larger the width of the projected picture at the same projection distance, that is, the larger the projected picture. Generally speaking, a projection ratio of less than 0.4 is the current ultra-short-throw / ultra-close-range projection. Preferably, the minimum focal length of the ultra-short-throw projection element 3 is greater than or equal to 10 cm, so that the quality of the projected picture obtained is higher.
[0055] Continue to refer Figures 1 to 5 As shown, in some embodiments, the projection image projected by the ultra-short-throw projection element 3 is located in the first adjacent area 11 of the backrest portion 1 adjacent to the headrest portion 2. Such projection can provide a more comfortable viewing angle for rear passengers.
[0056] refer to Figure 3 as well as Figure 4 As shown, in some embodiments, as Figure 3 As shown, the ultra-short-throw projection element 3 is rotatably connected to the headrest 2, and the headrest 2 can move from a first height position 201 to a second height position 202 in the height direction relative to the backrest 1; when the headrest 2 is at the first height position 201, the ultra-short-throw projection element 3 is at a first rotation position 301 relative to the headrest 2, and the position of the projection image projected by the ultra-short-throw projection element 3 is located in the first adjacent area 11. Figure 4 As shown, when the headrest portion 2 moves from the first height position 201 to the second height position 202 , the ultra-short focus projection element 3 rotates from the first rotation position 301 to the second rotation position 302 , so that the position of the projection image projected by the ultra-short focus projection element 3 is still located in the first adjacent area 11 .
[0057] It can be understood that in the above description, the structure that enables the headrest portion 2 to move from the first height position 201 to the second height position 202 relative to the backrest portion 1 in the height direction can be, for example, as follows: Figure 1 Through the adjustment of the headrest rod 22, the headrest rod 22 is generally provided with a related limiting mechanism to prevent excessive movement and excessive pulling and loosening of the wiring harness.
[0058] Preferably, the size of the projected image projected by the ultra-short-throw projector 3 is 12 inches to 15 inches, so that the rear space of the backrest of the seat can be fully utilized to provide a better audio-visual experience. Preferably, the area of the backrest 1 corresponding to the projected image projected by the ultra-short-throw projector 3 is at least mostly a plane, that is, the projected area of the backrest 1 is the part close to the middle plane, which further improves the visual perception of the projected image by the rear users.
[0059] contrast Figure 1 , Figure 5 As shown in Figure 1 In the embodiment shown, the headrest portion 2 includes a headrest body 21, and an ultra-short-throw projection element 3 is disposed at a second adjacent area 23 of the bottom of the headrest body 21 adjacent to the backrest 1. Figure 5 The structure shown integrates an ultra-short-throw projection element 3 .
[0060] exist Figure 5 In the illustrated embodiment, the headrest portion 2 includes a headrest body 21 and an extension portion 24 extending rearward from the headrest body 21 , and an ultra-short-throw projection element 3 is disposed at the rear end of the extension portion 24 . Figure 5 The embodiment shown is particularly suitable for Figure 5 The headrest portion 2 shown has a relatively thin structure.
[0061] As introduced above, the present application also provides a vehicle 1000, which may include the seat 100 introduced in the above embodiment. It can be understood that the use of the seat 100 in the vehicle provides the rear passengers with a better visual perception of the seat and a good audio-visual experience.
[0062] In summary, the beneficial effects of the seat and the vehicle described in the above embodiments include but are not limited to:
[0063] By arranging an ultra-short-throw projector on the headrest of the seat, and the projection direction of the ultra-short-throw projector is toward the backrest, that is, the lens of the ultra-short-throw projector is oriented downward from the headrest to the backrest, so that it will not affect the overall visual perception of the seat by the occupant. In addition, the structure of integrating the ultra-short-throw projector into the headrest not only makes the seat compact, but also has better stability of the projection image, which is particularly suitable for maintaining the stability of the projection image in the moving scene of the vehicle to ensure the user experience of the vehicle occupants.
