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.
[0054] 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.
[0055] refer to Figures 1 to 7 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 .
[0056] 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.
[0057] like Figure 1 or Figure 6 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, or the headrest body 21 can be directly connected to the backrest 1 by relative sliding, for example, by a structure such as a slide rail, and the like, and the headrest 2 can also be directly connected to the backrest 1 in an integral manner, and the headrest 2 can also be directly connected to the backrest 1 in an integral manner, and the like ...
[0058] The backrest 1 is provided with an ultra-short-focus projection element 3, which is arranged inside the backrest 1; the projection direction of the ultra-short-focus projection element 3 is from the backrest 1 toward the headrest 2; the projection image projected by the ultra-short-focus projection element 3 is located in the first adjacent area 11 of the backrest 1 adjacent to the headrest 2, and / or in the second adjacent area 23 at the bottom of the headrest 2 adjacent to the backrest 1.
[0059] Continue to refer Figures 1 to 6 As shown, especially Figure 3 as well as Figure 4 As shown, in some embodiments, the backrest portion 1 is provided with an ultra-short-throw projection element 3 , and the ultra-short-throw projection element 3 is arranged inside the backrest portion 1 in a pop-up manner.
[0060] Specifically, in Figure 3 In the first state of the seat 100 shown, the ultra-short-throw projection element 3 is located inside the backrest portion 1 .
[0061] exist Figure 4 In the second state of the seat 100 shown, the ultra-short-focus projection element 3 is located outside the backrest 1, and the projection direction of the ultra-short-focus projection element 3 is from the backrest 1 toward the headrest 2, and the projection image projected by the ultra-short-focus projection element 3 is displayed on the headrest 2 or the backrest 1.
[0062] Continue to refer Figures 1 to 6 As shown, in some embodiments, the structure for realizing the pop-up setting of the ultra-short-throw projection element 3 can be realized by a push-press platform 4. The push-press platform 4 carries the ultra-short-throw projection element 3, and in the first state of the seat 100, the push-press platform 4 is located inside the backrest 1; the push-press platform 4 can pop out of the backrest 1, so that the ultra-short-throw projection element 3 is located outside the backrest 1.
[0063] The meaning of the push-and-press platform 4, as the name implies, can realize the switching between ejection and return by the operator's pressing, for example, the ejection and return structure of a common optical drive can be referred to. The power of ejection can be driven by a motor. It can be understood that the push-and-press platform 4 is not limited to being opened only by the user's pressing, for example, the user can also send a driving signal to the driving motor by remote control to make it push the push-and-press platform 4 to eject. The structure of the push-and-press platform 4 has the beneficial effect that its structure is relatively mature and reliable, and is easy to implement in the seat.
[0064] 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 push-pressing platform 4 for heat dissipation of the ultra-short-throw projection element 3. The driving source of the heat dissipation fan may be a pump provided inside the backrest 1, especially when the seat has an inflatable massage function, the driving source of the heat dissipation fan may be a pump using an inflatable massage function, thereby further improving the integration of the seat.
[0065] The ultra-short focus projection here can also be called ultra-close-range projection, and its meaning is similar to that in the projection field, that is, the projection equipment 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 greater 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 focus / ultra-close-range projection. Preferably, the minimum focal length of the ultra-short focus projection component 3 is greater than or equal to 10 cm, so that the quality of the projected picture obtained is higher. Preferably, the size of the projected image projected by the ultra-short focus projection component 3 is 12 inches to 15 inches, so that the back space of the seat back or the headrest can be fully utilized to provide a better audio-visual experience. It can be understood that, for example Figure 1 As shown, the size of the image projected onto the headrest 2 is generally smaller than the size of the image projected onto the backrest 1, and can be flexibly selected according to actual needs. Preferably, the area of the backrest 1 or the headrest 2 corresponding to the projection image projected by the ultra-short-throw projection element 3 is at least partially a plane, that is, the area projected onto the backrest 1 and the headrest 2 at least includes a portion of the plane close to the middle, which further enhances the visual perception of the projection image for the rear row users.
[0066] The wiring harness connected to the ultra-short-throw projection element 3 can generally be located inside the backrest 1, 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 ultra-short-throw projection element 3 can also be connected to the projection image signal input source through wireless transmission methods such as Bluetooth and WiFi. The input source is not limited to the image signal input source of the vehicle itself, but can also be obtained from the cloud or the user's mobile terminal, such as the user's mobile phone, tablet computer, etc., to further meet the user's audio-visual needs.
[0067] Preferably, in some embodiments, Figure 5 as well as Figure 6 As shown, the ultra-short-throw projection member 3 is rotatably connected to the push-pressing platform 4, for example, by a hinge connection. Such a structure is simple and reliable. The headrest portion 2 can be adjusted in height relative to the backrest portion 1. Figure 5 The first height position 201 shown moves to Figure 6 When the headrest 2 is at the first height position 201, the ultra-short-throw projection element 3 is at the 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 second adjacent area 23; when the headrest 2 moves from the first height position 201 to the second height position 202, the ultra-short-throw projection element 3 rotates from the first rotation position 301 to the second rotation position 302, and the position of the projection image projected by the ultra-short-throw projection element 3 is still located in the second adjacent area 23. In this way, the position of the projected image can be further stabilized and will not change significantly with the change in the height of the headrest 2, further improving the viewing experience of the user.
[0068] Continue to refer Figure 1 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 1 adjacent to the headrest 2, or in the second adjacent area 23 of the bottom of the headrest 2 adjacent to the backrest 1. This can meet the viewing requirements of users in different sitting postures, especially in the case of zero-gravity seats in the back row with a large sitting adjustment angle, further improving the viewing experience of passengers.
[0069] refer to Figure 7 As shown, in other embodiments, Figures 1 to 6 Similar to the illustrated embodiment, the backrest 1 is provided with an ultra-short-focus projection element 3, which is arranged inside the backrest 1; the projection direction of the ultra-short-focus projection element 3 is from the backrest 1 toward the headrest 2; the projection image projected by the ultra-short-focus projection element 3 is located in the first adjacent area 11 of the backrest 1 adjacent to the headrest 2, and / or in the second adjacent area 23 at the bottom of the headrest 2 adjacent to the backrest 1.
[0070] But with Figures 1 to 6 The difference is, Figure 7 In the embodiment shown, a fixed bracket 5 is disposed inside the backrest 1, and the ultra-short-throw projection element 3 is disposed on the fixed bracket 5. The fixed bracket 5 here means that its position is fixed, not Figures 1 to 6 The position of the ultra-short-throw projector 3 can be changed in different states, that is, the position of the ultra-short-throw projector 3 is also located inside the backrest of the seat during use. Figure 7 In the embodiment shown, the ultra-short-throw projection element 3 provides a projection light path from the inside of the seat backrest 1 to the back of the seat when in operation, which may be the back of the backrest 1 and / or the back of the headrest 2. It can be understood that if the backrest 1 and the headrest 2 are separated rather than integrated, then the projection can only be onto the back of the backrest 1. When the backrest 1 and the headrest 2 are an integrated connection structure, then the projection can be onto the back of the headrest 2. Figure 7 As shown, the first adjacent area 11 of the backrest 1 and / or the second adjacent area 23 of the headrest 2 are correspondingly provided with a transparent projection screen 6 or an electrochromic glass 7, so that the projection light path can form a projection image from the inside of the seat to the back of the seat. It can be understood that the meaning of the transparent projection screen 6 is similar to that in the field of projection, but it is different from an ordinary screen in that, due to the projection from the inside to the outside, the projection screen 6 here needs to be transparent. For example, a holographic film can be provided on the inner side of the transparent projection screen 6. Similarly, when projection is required, the electrochromic glass 7 turns into the color of the screen after power is turned on. In addition, since it is a projection from the inside to the outside, compared to Figures 1 to 6 An embodiment of Figure 7 The projection image signal in the illustrated embodiment generally requires mirror processing. In addition, since the projection component is kept inside the backrest 1, the wiring harness is hidden inside the seat back plate, connected to the power supply and the image signal input source respectively, the integration and appearance of the structure are better.
[0071] Preferably, in some embodiments, the back of the backrest 1 is provided with heat dissipation holes for dissipating heat from the ultra-short-throw projection element 3, thereby further ensuring reliable heat dissipation of the ultra-short-throw projection element 3 disposed inside. Figures 1 to 6 Similar to the embodiment shown, a heat dissipation fan and heat dissipation holes may be arranged inside or near the fixing bracket 5 .
[0072] 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.
[0073] In summary, the beneficial effects of the seats and vehicles introduced in the above embodiments include but are not limited to: achieving the integrity of the seat back while providing a better audio-visual experience. Specifically, by arranging a pop-up ultra-short-focus projection component on the backrest, when not in use, the ultra-short-focus projection component can be hidden inside the backrest, and when needed, the ultra-short-focus projection component can be popped out to the outside of the backrest, so that the installation space of the backrest can be fully utilized, and the setting of the ultra-short-focus projection component is avoided to affect the overall look and feel of the seat. In addition, the use of a pop-up ultra-short-focus projection component not only makes the seat structure 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 passengers. In addition, the solution of keeping the ultra-short-focus projection component inside the seat can also be adopted, so that the overall look and feel of the seat back can be maintained in the use and non-use states.
[0074] Although the present application is disclosed as above with preferred embodiments, it is not intended to limit the present application, and any person skilled in the art may make possible changes and modifications without departing from the spirit and scope of the present application. Therefore, any modification, equivalent change and modification made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application shall fall within the scope of protection defined by the claims of the present application.
