[0035] In the terminal equipment used for users to sit, in order to allow users to use the facilities configured in the terminal equipment more comfortably and obtain a better user experience, the user's head needs to have a relatively fixed position inside the cabin to meet the optimal sensory position when the terminal is set up and designed, thereby obtaining a better sensory and user experience. However, different people have different body characteristics, such as height, weight, and different people have different requirements for different postures of seats. Therefore, a seat structure with adjustable sitting posture but relatively fixed head position inside the cabin is urgently needed to meet the above requirements.

[0036] In view of this, the present invention proposes a chair, see the attached Figure 1 To Attachment Figure 7 , is an embodiment of the seat proposed in this application, and the seat will be described in detail below with reference to specific drawings.

[0037] See also Figure 1 , the chair 100 is applied to a terminal device, wherein the chair 100 includes a mounting base 1, a seat 2, a seat back 3 and a transmission structure, the mounting base 1 is used to be fixed in the cabin of the terminal device, the mounting base 1 includes a base 11 and a support frame 12 arranged on the rear side of the base 11; the seat 2 is movably mounted on the base 11 in the front-to-back direction so as to approach or move away from the support frame 12 in the front-to-back direction; the upper end of the seat back 3 is rotatably mounted on the support frame 12 around the left and right axial direction so that the lower end of the seat back 3 can swing in the front-to-back direction; the transmission structure is arranged between the seat 2 and the seat back 3 to drive the lower end of the seat back 3 to swing in the front-to-back direction when the seat 2 moves in the front-to-back direction.

[0038] In the technical solution of the present invention, the chair 100 is composed of the mounting base 1, the chair back 3 and the seat 2. Specifically, the mounting base 1 includes the base 11 and the support frame 12 located at the rear side of the base 11, and the chair back 3 and the seat 2 are independently arranged, and the upper end of the chair back 3 can be rotatably installed on the support frame 12, and the seat 2 can be movably installed on the base 11 in the forward and backward directions. The transmission structure is also provided between the seat 2 and the chair back 3, and the transmission structure is used for transmission connection, so that the seat 2 can drive the chair back 3 to rotate around its upper end during the forward and backward movement. The axis rotates to drive the lower end of the chair back 3 to swing in the front and rear directions, so that the posture of the seat 100 can be adjusted to meet the different sitting posture requirements of the seat 100 and the usage requirements of users of different body shapes. On this basis, since the upper end of the chair back 3 is rotatably installed on the support frame 12, and the user's head is correspondingly located on the top of the chair back 3, during the rotation of the chair back 3, its position corresponding to the user's head hardly changes, so that the position of the user's head hardly moves, thereby keeping the user's head relatively fixed in the terminal device, so that the user has a better audio-visual experience and meets functional requirements.

[0039] Specifically, it can be understood that the movement path of each point on the seat 2 is movement in the front-to-back direction, and the movement path of each point on the seat back 3 is rotation around the rotation axis of the seat back 3, that is, in addition to movement in the front-to-back direction, it also has movement in the up-and-down direction, but its front-to-back direction movement is linked with the up-and-down direction movement, that is, when the front-to-back direction movement of the seat 2 drives the seat back 3 to be displaced in the front-to-back direction, it must also have movement in the up-and-down direction, so as to realize the posture adjustment of the chair 100. Based on this, the transmission structure movably connects the seat 2 and the seat back 3 at least in the front-to-back direction, that is, the seat 2 can drive the seat back 3 to move, thereby realizing the above-mentioned function. Specifically, in the present application, the transmission structure is set to a connecting part and a matching part separately arranged on the seat 2 and the seat back 3, and the connecting part and the matching part are movably connected at least in the front-to-back direction to meet the above-mentioned functional requirements.

[0040] Further, see Figure 2The specific structural setting of the transmission structure can be various, as long as it can meet the above requirements. For example, the seat 2 and the seat back 3 can be connected by a deformable structure. However, when connected by a deformable structure, the relative position between the seat 2 and the seat back 3 is not fixed, that is, when subjected to force, the deformable structure will also deform, which will cause the sitting posture of the chair 100 to change, affecting the user experience. Therefore, the transmission structure needs to be set as a rigid connection structure, and when setting the rigid connection structure, it is necessary to consider the relative movement of the seat 2 and the seat back 3 in the up and down directions. Therefore, the connecting part and the matching part need to have a matching margin in the up and down directions to avoid the relative movement of the seat 2 and the seat back 3 in the up and down directions causing the connecting part and the matching part to be stuck. Based on this, in this embodiment, a guide groove 41 is provided on one of the seat 2 and the seat back 3, and the guide groove 41 extends in the front-to-back direction and is arranged at a certain angle to the horizontal direction. The guide slot 41 forms the matching portion, wherein another portion is provided with a guide post 5 extending into the guide slot 41, and the guide post 5 can move along the guide slot 41 to form the connecting portion, and the guide post 5 can move along the guide slot 41, so that the guide post 5 abuts against the slot wall of the guide slot 41 in the front-to-back direction to achieve the movable connection between the guide post 5 and the guide slot 41 in the front-to-back direction, and the guide slot 41 is set at a certain angle to the horizontal direction, so that the guide post 5 has a movable margin in the up-and-down direction during the movement of the guide post 5 in the guide slot 41, so as to avoid the situation where the guide post 5 and the guide slot 41 are stuck when the seat 2 and the seat back 3 move relative to each other in the up-and-down direction, thereby meeting the above-mentioned structural function requirements, and after the seat 2 is adjusted into place, the guide post 5 abuts against the slot wall of the guide slot 41 to form a rigid connection, and the force applied by the user during use will not cause the seat back 3 to rotate, thereby avoiding the sitting posture of the chair 100 to change.

[0041] Furthermore, if the guide column 5 extends into the guide groove 41 unidirectionally, that is, the guide column 5 forms a cantilever structure, the structural stability of which is poor. After long-term use, the guide column 5 may be deformed, affecting the adjustment of the seat 2 and the chair back 3. Therefore, in this embodiment, the guide groove 41 is penetrated upward in the left and right directions, so that the guide column 5 can be penetrated in the guide groove 41 in the left and right directions. In this way, both ends of the guide column 5 can be fixed to ensure the reliability of the guide column 5 structure.

[0042] Furthermore, if the guide post 5 moves in the guide groove 41 in a sliding manner, there will be a problem of wear, which affects the service life of the seat 100. Therefore, the present application aims to adjust the movement of the guide post 5 relative to the guide groove 41 to rolling. In some embodiments, the guide post 5 can be directly set as a rolling structure, and in other embodiments, a rolling member 51 is sleeved at the position of the guide post 5 corresponding to the guide groove 41, which meets the requirements and can extend the service life of the seat 100. In this embodiment, the method of sleeve-mounting the rolling member 51 on the guide post 5 is selected, which has a simple structure, is easy to install, and is easy to disassemble and assemble.

[0043] Furthermore, if the method of sleeve-mounting the rolling member 51 on the guide column 5 is adopted, it is necessary to ensure that the rolling member 51 is located in the guide groove 41 to ensure its transmission function. Therefore, in order to prevent the rolling member 51 from escaping from the guide groove 41 in the left-right direction, a stopper is further provided in the guide groove 41 in the present embodiment to limit the position of the rolling member 51 in the left-right direction through the stopper.

[0044] Further, see Figure 4 , the specific arrangement of the guide groove 41 and the guide column 5 is not actually limited. For example, the guide groove 41 can be directly opened on the main body of the seat 2 or the seat back 3, but it is obvious that the structural molding is more complicated. Therefore, in this embodiment, the guide groove 41 and the guide column 5 are set independently of the main body of the seat 2 and the seat back 3, that is, a guide part 4 is provided on one of the seat 2 and the seat back 3, and the guide part 4 is detachably arranged, and the guide groove 41 is penetrated along the left and right sides of the guide part 4. At the same time, the guide column 5 can be detachably installed on the other one of the seat 2 and the seat back 3, and the guide column 5 is inserted into the guide groove 41, so as to realize the guide column 5 cooperates with the guide groove 41. On the basis of the above-mentioned detachable setting structure, the fixed stopper set in the guide groove 41 will affect the disassembly and assembly of the guide column 5. Therefore, in this embodiment, the cover plate 42 is set at the notch of the guide groove 41, and the stopper is formed by the cover plate 42. A slot is opened on the cover plate 42, and the guide column 5 is penetrated through the slot. During the installation of the guide column 5, after the rolling element 51 is sleeved on the guide column 5, the guide column 5 is passed through the guide groove 41, and then the cover plate 42 is sleeved on the guide column 5, and the cover plate 42 is moved to the notch of the guide groove 41 and fixed. In this way, the limiting of the rolling element 51 is completed, and the operation is convenient and easy to replace.

[0045] In addition, in order to prevent the rolling member 51 placed in the guide groove 41 from having a movable gap in the left and right directions and upward directions, thereby causing the rolling member 51 to move in an unstable manner in the guide groove 41 and possibly become stuck, a sleeve 52 is also sleeved on the guide column 5, and the sleeve 52 is arranged between the rolling member 51 and the stopper to limit the rolling member 51. Of course, the size of the rolling member 51 can be processed according to the size of the guide groove 41, which can also meet the limiting function. Here, it is mainly for the rolling member 51 to be a standard part or a workpiece that is difficult to process, and it can be adjusted by additionally setting the sleeve 52 with a simple structure and easy processing, which is relatively more practical.

[0046] Specifically, the rolling element 51 includes a bearing, and the sleeve 52 is arranged corresponding to the inner ring of the bearing. The rolling element 51 is arranged as the bearing, which has mature technology, low cost, and small rolling resistance, and the sleeve 52 is arranged corresponding to the inner ring of the bearing to avoid the sleeve 52 affecting the rotation of the bearing.

[0047] The present invention also proposes a terminal device, which includes a cabin and a seat 100, wherein the seat 100 is installed in the cabin. The specific structure of the seat 100 refers to the above-mentioned embodiment. Since the terminal device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0048] It is understandable that the terminal device includes an audio-visual cabin or a vehicle cabin, or other application scenarios in which the seat 100 can be applied. Moreover, the cabin of the terminal device may include audio-visual equipment, or only speakers, or other equipment and structures adapted to the functions of the terminal device, which are not specifically limited here.

[0049] This application mainly involves the field of immersive panoramic sound smart cockpits. Because of the setting of the sound field, in order to allow users to enjoy high-quality sound sensations, the user's head needs to have a relatively fixed position inside the cockpit to fit the sound field, thereby obtaining a higher sound quality experience. Therefore, in this embodiment, the terminal device mainly includes the audio-visual cockpit, and the cabin of the audio-visual cockpit includes at least the speaker device to provide users with a more immersive vocal experience.

[0050] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
