[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0027] The following is for reference. Figure 1 and Figure 2 Describes a seat assembly 100 according to a first aspect embodiment of the present invention.

[0028] like Figure 1 and Figure 2 As shown, the seat assembly 100 according to the first aspect of the present invention includes: a seat body, an augmented reality device 10, and a support arm 20.

[0029] Specifically, the support arm 20 is connected between the extended reality device 10 and the seat body. The extended reality device 10 has a viewing window 11 on the side facing the seat body. The support arm 20 is rotatably connected to one side of the seat body in the left-right direction. The support arm 20 is configured to have an adjustable length between the extended reality device 10 and the seat body.

[0030] Among them, the extended reality device 10 can be a virtual reality device (VR device), an augmented reality device (AR device), or a mixed reality device (MR device).

[0031] The left and right directions of the seat body refer to the left and right directions of the user when the user is sitting normally on the seat body.

[0032] When the user is not using the extended reality device 10, the extended reality device 10 is in a stored state. For example, the extended reality device 10 can be stored behind the seat body.

[0033] When a user is sitting on the seat and using the augmented reality device 10, the user rotates the augmented reality device 10 upwards and adjusts the length of the support arm 20 between the augmented reality device 10 and the seat body. This allows the augmented reality device 10 to move around the top of the seat body and move to the front of the user, positioning the viewing window 11 opposite the user's eyes. Then, the length of the support arm 20 between the augmented reality device 10 and the seat body is adjusted so that the viewing window 11 is close to the user's eyes. This allows the user to wear the augmented reality device 10, and since the augmented reality device 10 is connected to the seat body via the support arm 20, the burden on the user caused by the augmented reality device 10 can be reduced.

[0034] After the user finishes using the extended reality device 10, the user first increases the length of the support arm 20 between the extended reality device 10 and the seat body, so that the extended reality device 10 is away from the user. Then, the user rotates the extended reality device 10 backward so that it goes around the upper side of the seat body until it is rotated to a designated position on the rear side of the seat body. In this way, the extended reality device 10 can be stored after the user takes it off.

[0035] Understandably, during the process of the user moving the extended reality device 10, the support arm 20 can guide and limit the extended reality device 10, allowing it to move and rotate within a set stroke. This makes it easier for the user to control the movement path of the extended reality device 10. In the confined space inside the vehicle, the user can more easily and conveniently adjust the extended reality device 10 into position, thereby reducing the operational difficulty for the user when using the extended reality device 10.

[0036] Preferably, there are two support arms 20. One end of each support arm 20 is connected to the left and right sides of the seat body, and the other end of each support arm 20 is connected to both ends of the extended reality device 10. This can improve the reliability and stability of the connection between the extended reality device 10 and the seat body.

[0037] According to the seat assembly 100 of the first aspect of the present invention, when a user puts on and takes off the extended reality device 10, the extended reality device 10 can be adjusted to a suitable position and angle by rotating the support arm 20 and adjusting the length of the support arm 20 between the extended reality device 10 and the seat body. The support arm 20 can guide and limit the movement of the extended reality device 10. The user's movement is small and the movement is easy, thereby reducing the difficulty of putting on and taking off the extended reality device 10. Furthermore, the seat body supports the extended reality device 10, reducing the burden on the user and improving the user experience.

[0038] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the seat body has a pivot 41 on one side in the left-right direction. The seat assembly 100 also includes a knob 30 with a rotating hole formed on the knob 30. The pivot 41 is fitted into the rotating hole, and the support arm 20 is connected to the knob 30.

[0039] By setting the knob 30, the size of the knob 30 can be adjusted during the product design process to make the knob 30 fit with the rotating shaft 41. This allows the support arm 20 to be adapted to rotating shafts 41 of different sizes. Furthermore, the material used at the knob 30 can be increased to enhance the connection strength between the knob 30 and the rotating shaft 41. This reduces the need for changes to the structure of the support arm 20 during the product design process and lowers the difficulty of product design.

[0040] In some embodiments of this utility model, a mounting cavity is formed inside the knob 30, and the rotating hole communicates with the mounting cavity. The rotating shaft 41 extends into the mounting cavity through the rotating hole. The seat assembly 100 also includes: a first locking member and a locking gear. The first locking member and the locking gear are disposed in the mounting cavity. The first locking member is connected to the inner wall of the mounting cavity. The locking gear is sleeved on the rotating shaft 41. The first locking member is adapted to mesh with the locking gear so that the knob 30 is locked on the rotating shaft 41.

[0041] When the user needs to rotate the support arm 20, the user operates the first locking member to disengage from the locking gear. At this time, the knob 30 can rotate freely around the rotating shaft 41. When the support arm 20 rotates to a suitable angle, the user operates the first locking member to engage with the locking gear. In this way, the knob 30 and the rotating shaft 41 are fixed relative to each other. Thus, the angle of the extended reality device 10 relative to the seat body can be fixed.

[0042] The locking method of the first locking element and the locking gear is relatively simple. The locking gear has teeth on its circumference and the structure of the locking gear is relatively simple. In product design, it is relatively easy to arrange the first locking element and the locking gear in the knob 30, and it is relatively easy to make the cooperation logic between the first locking element and the locking gear meet the usage requirements.

[0043] In some embodiments of this utility model, the first locking member is provided with a first unlocking part and a first locking part. The first locking member is rotatably connected to the inner wall of the mounting cavity. The first unlocking part and the first locking part are respectively provided on both sides of the rotation axis of the first locking member. A first unlocking hole communicating with the mounting cavity is formed on the knob 30. The first unlocking part extends out of the mounting cavity through the first unlocking hole. The first locking part is adapted to engage with the locking gear. The seat assembly 100 also includes: a first reset member. The first reset member is connected between the first locking member and the inner wall of the mounting cavity. The first reset member is configured to apply a force to the first locking member to rotate the first locking part toward the locking gear.

[0044] When the user needs to rotate the support arm 20, the user can press the first unlocking part with the force of the first reset member and rotate the first locking member. The first locking part gradually rotates away from the locking gear. At the same time, the first reset member applies a force to the first locking member to make the first locking part rotate toward the locking gear. When the first locking part disengages from the locking gear, the first locking member releases the lock between the knob 30 and the rotating shaft 41. The user can freely rotate the support arm 20. When the user rotates the support arm 20 to a suitable angle, the user releases the pressure on the first unlocking part. Under the action of the first reset member, the first locking part rotates toward the locking gear until it engages with the locking gear. Thus, the angle of the support arm 20 can be locked.

[0045] The first unlocking part and the first locking part are located on opposite sides of the rotation axis of the first locking member. A first reset member applies a force to the first locking member, causing the first locking part to rotate towards the locking gear. When the knob 30 is locked on the rotating shaft 41, the force of the first reset member improves the reliability of the engagement between the first locking part and the locking gear, thereby improving the reliability of the angle locking of the support arm 20. To unlock, the user simply presses down on the first unlocking part against the force of the first reset member, making the operation relatively simple. To relock, the user releases the first unlocking part, and under the action of the first reset member, the first locking part rotates to engage with the locking gear, thus automatically locking the knob 30 on the rotating shaft 41. This further reduces the operational difficulty for users when using the extended reality device 10.

[0046] Preferably, the first reset element is a reset spring, which is easier to arrange within the knob 30, thus further reducing the difficulty of product design.

[0047] In some embodiments of this utility model, a guide hole is formed on the knob 30 extending along the length direction of the support arm 20, and the support arm 20 is movably disposed in the guide hole along the length direction.

[0048] During the operation of the extended reality device 10 by the user, when it is necessary to adjust the distance between the extended reality device 10 and the seat body, the extended reality device 10 is pushed so that the support arm 20 moves along the length direction of the support arm 20 in the guide hole. In this way, the length of the support arm 20 between the extended reality device 10 and the seat body can be adjusted, thereby realizing the adjustment of the distance between the extended reality device 10 and the seat body.

[0049] Specifically, the length of the support arm 20 between the extended reality device 10 and the seat body is adjusted by moving the support arm 20 within the guide hole. The guide hole guides and limits the movement of the support arm 20, and the operation is relatively simple for the user, thus further reducing the difficulty of using the extended reality device 10. In addition, the cooperation structure between the guide hole and the support arm 20 is relatively simple, which can reduce the difficulty of product design.

[0050] In some embodiments of this utility model, the support arm 20 is provided with a rack segment, which is disposed in a guide hole. The knob 30 is also provided with a second unlocking hole communicating with the guide hole. The seat assembly 100 further includes: a second locking member and a second resetting member. The second locking member and the second resetting member are disposed in the guide hole. The second locking member is provided with a second unlocking part and a second locking part. The second locking member is rotatably connected to the inner wall of the guide hole. The second unlocking part and the second locking part are respectively disposed on both sides of the rotation axis of the second locking member. The second unlocking part extends out of the guide hole through the second unlocking hole. The second locking part is adapted to engage with the rack segment. The second resetting member is connected between the inner wall of the guide hole and the second locking member. The second resetting member applies a force to the second locking member to rotate the second locking part toward the rack segment.

[0051] During the operation of the extended reality device 10, when it is necessary to adjust the distance between the extended reality device 10 and the seat body, the user overcomes the force of the second reset member, presses the second unlocking part, and rotates the second locking member. The second locking part gradually rotates away from the rack segment. At the same time, the second reset member applies a force to the second locking member to rotate the second locking part toward the rack segment. When the second locking part disengages from the rack segment, the second locking member releases the lock between the knob 30 and the support arm 20. The user can freely move the support arm 20 in the guide hole. When the user moves the support arm 20 to a suitable position, the user releases the pressure on the second unlocking part. Under the action of the second reset member, the second locking part rotates toward the rack segment until it engages with the rack segment. Thus, the length of the support arm 20 between the extended reality device 10 and the seat body can be locked.

[0052] The second unlocking part and the second locking part are located on opposite sides of the rotation axis of the second locking member. A second reset member applies a force to the second locking member, causing the second locking part to rotate towards the rack segment. When the support arm 20 is locked on the knob 30, the force of the second reset member improves the reliability of the engagement between the second locking part and the rack segment, thereby improving the reliability of the length locking of the support arm 20. To unlock, the user simply presses down on the second unlocking part against the force of the second reset member, making the operation relatively simple. To relock, the user releases the second unlocking part, and under the action of the second reset member, the second locking part rotates to engage with the rack segment, thus automatically locking the support arm 20 on the knob 30. This further reduces the operational difficulty for users when using the extended reality device 10.

[0053] In some embodiments of this utility model, the support arm 20 includes: a plurality of support segments, which are sequentially connected between the extended reality device 10 and the seat body, and one of two adjacent support segments is provided with a telescopic hole extending along the length direction of the support segment, and the other of two adjacent support segments is movably extended into the telescopic hole along the length direction of the support arm 20. For example, there can be two, three or four support segments.

[0054] During the operation of the extended reality device 10 by the user, when the user pushes the extended reality device 10 away from the seat body, the support section is gradually pulled out from the telescopic hole. As a result, the length of the support arm 20 between the extended reality device 10 and the seat body can be increased, thereby increasing the distance between the extended reality device 10 and the seat body.

[0055] When the user pushes the extended reality device 10 toward the seat body, the support section gradually extends into the telescopic hole, thereby reducing the length of the support arm 20 between the extended reality device 10 and the seat body, thus reducing the distance between the extended reality device 10 and the seat body.

[0056] This allows for adjustment of the length of the support arm 20 between the seat body and the augmented reality device 10, and reduces the space occupied by the support arm 20, thereby reducing the interference of the support arm 20 with the occupants in the vehicle and facilitating the arrangement of the support arm 20 within the vehicle.

[0057] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the seat body includes: a headrest 40, and a support arm 20 that is rotatably connected to one side of the headrest 40 in the left-right direction.

[0058] Understandably, the headrest 40 is close to the user's head. It is connected to the headrest 40 via the support arm 20. When the user adjusts the position of the extended reality device 10, it is easier to align the viewing window 11 with the user's glasses. Furthermore, the extended reality device 10 has a shorter length to go around the support arm 20 from the top of the headrest 40, which reduces the space occupied by the support arm 20 and the space occupied by the extended reality device 10 during movement. This reduces the interference of the support arm 20 with the occupants in the vehicle and improves the user's riding experience.

[0059] Preferably, there are two support arms 20. One end of each support arm 20 is connected to the left and right sides of the headrest 40, and the other end of each support arm 20 is connected to both ends of the extended reality device 10. This can improve the reliability and stability of the connection between the extended reality device 10 and the headrest 40.

[0060] In some embodiments of this invention, a speaker is provided on at least one side of the headrest 40 in the left-right direction, and the speaker is electrically connected to the extended reality device 10. That is, the headrest 40 may have a speaker on one side in the left-right direction, or the headrest 40 may have speakers on both sides in the left-right direction.

[0061] In this way, the speaker is close to the user's head, which reduces interference to other passengers, provided that the speaker's loudness meets the user's needs on the seat.

[0062] Preferably, the speaker is located inside the knob 30, and the power supply harness of the vehicle passes through the headrest 40 and extends into the knob 30 to connect with the speaker.

[0063] The vehicle according to a second aspect of the present invention includes: the seat assembly 100 according to the first aspect of the present invention.

[0064] According to the second aspect of the present invention, by providing the seat assembly 100 according to the first aspect of the present invention, the difficulty of the user putting on and taking off the extended reality device 10 can be reduced, and the burden of the extended reality device 10 on the user can be reduced, thereby improving the user experience.
