Description

Technical Field

[0001] The utility model relates to the field of automobile interior decoration, in particular to an automobile seat structure. Background Art

[0002] As people's demand for seat functions gradually increases, current car seats can no longer meet the needs of passengers. Car seats are no longer limited to providing a good driving or riding posture. Car seat backs can basically be rotated and adjusted backward to provide a better relaxation and rest state. However, most existing car seats can only be adjusted backward to a maximum inclination angle of 135 degrees with the seat cushion, but this cannot achieve a more comfortable state for most passengers. There is still a step difference between the existing seat backs that can be fully reclined and the seat cushion, and passengers still feel uncomfortable when lying flat.

[0003] The technical problem to be solved by this application is: how to improve the comfort of the seat after the backrest is fully reclined. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the present invention aims to provide a seat structure in a large bed mode.

[0005] The technical solution adopted by the present invention is: a seat structure in a large bed mode, including a seat cushion frame, a backrest frame and an angle adjustment structure, the angle adjustment structure includes a connecting piece, a first angle adjuster and a second angle adjuster, the bottom end of the backrest frame is rotatably connected to one end of the connecting piece through the first angle adjuster, and the rear end of the seat cushion frame is rotatably connected to the other end of the connecting piece through the second angle adjuster.

[0006] In some embodiments, first recliners are respectively provided on both sides of the backrest frame, and the two first recliners are connected via a first rotating shaft.

[0007] In some embodiments, a second recliner is provided on each side of the seat cushion frame, and the two second recliners are connected via a second rotating shaft.

[0008] In some embodiments, the angle adjustment structure includes a first driving element and a second driving element. The first driving element drives the first angle adjuster to work, and the first driving element is set on the backrest frame. The second driving element drives the second angle adjuster to work, and the second driving element is set on the seat cushion frame.

[0009] In some embodiments, the cross-section of the connecting member is stepped, and one end of the connecting member connected to the seat cushion frame is arranged on the inner side of the seat cushion frame.

[0010] In some embodiments, the first driving element is disposed on an inner side of the backrest frame, and the second driving element is disposed on an inner side of the seat cushion frame.

[0011] The beneficial effects of the present invention are:

[0012] The seat structure of the king-size bed mode adopts a double-angle adjustment design. When in the king-size bed mode, the double-angle adjustment design can make the backrest and the seat cushion have no step difference, so that the seat structure forms a king-size bed mode with good comfort and flatness, thereby improving the comfort of passengers when resting, and does not affect the daily adjustment of the backrest angle during driving.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1 and Figure 2 The present invention provides a technical solution: a large bed-mode chair structure comprising a seat cushion frame 1, a seat cushion cover 2, a backrest frame 3, a backrest cover 4, and an angle adjustment structure 5. The angle adjustment structure 5 is disposed between the seat cushion frame 1 and the backrest frame 3. The seat cushion cover 2 is fixedly mounted on the seat cushion frame 1, and the backrest cover 4 is mounted on the backrest frame 3.

[0018] The angle adjustment structure 5 includes a connector 51, a first drive element 52, a first rotating shaft 53, a first recliner 54, a second drive element 55, a second rotating shaft 56, and a second recliner 57. The first drive element 52 and the second drive element 55 are recliner motors. The backrest frame 3 is connected to the seat cushion frame 1 via the connector 51. The bottom end of the backrest frame 3 is connected to one end of the connector 51 for limited rotation. The connection position between the backrest frame 3 and the connector 51 is set to the first angle adjustment position. The rear end of the seat cushion frame 1 near the backrest frame 3 is connected to the other end of the connector 51 for limited rotation. The connection position between the seat cushion frame 1 and the connector 51 is the second angle adjustment position. The first angle adjustment position is set on both sides of the backrest frame 3, and the second angle adjustment position is set on both sides of the seat cushion frame 1. A first drive element 52 is disposed inside the backrest frame 3. The output end of the first drive element 52 is connected to a first rotating shaft 53, through which the backrest frame 3 is rotatably connected to the connector 51. The ends of the first rotating shaft 53 are respectively connected to first recliners 54 on either side of the backrest frame 3. The first recliners 54 are positioned in the first angle adjustment position and are fixedly connected to the connector 51. When the first drive element 52 is in operation, the backrest frame 3 rotates about the first angle adjustment position. A second drive element 55 is disposed inside the seat cushion frame 1. The output end of the second drive element 55 is connected to a second rotating shaft 56, through which the seat cushion frame 1 is rotatably connected to the connector 51. The ends of the second rotating shaft 56 are respectively connected to second recliners 57 on either side of the seat cushion frame 1. The second recliners 57 are positioned in the second angle adjustment position and are fixedly connected to the connector 51. When the second drive element 55 is in operation, the connector 51 rotates about the second angle adjustment position.

[0019] In order to save the lateral space of the seat, the cross section of the connecting member 51 is designed to be stepped, and the end of the connecting member 51 connected to the seat cushion frame 1 is arranged on the inner side of the seat cushion frame 1.

[0020] In order to make the seat more beautiful, the connecting member 51 is provided with a fixed side panel 58, and side baffles 59 are respectively provided on both sides of the seat cushion frame 1.

[0021] When the passenger is in a normal sitting position, the angle between the backrest frame 3 and the connecting member 51 is less than 30 degrees, so as to ensure that the subsequent rotation range of the connecting member 51 is large enough and the connection position between the backrest frame 3 and the sitting frame is smoother.

[0022] The working principle and usage process of the present invention are as follows: when a passenger needs to adjust the angle of the backrest frame 3, the first driving element 52 works, and the backrest frame 3 is adjusted to the angle required by the passenger; when the passenger needs to lay down the backrest frame 3, the backrest frame 3 maintains its original set position, the second driving element 55 works, and the backrest frame 3 and the connecting member 51 rotate together until the backrest frame 3 and the connecting member 51 are flattened to a relatively flat angle between the backrest frame 3 and the backrest cushion, and there is no step between the backrest frame 3 and the backrest cushion, so that the passenger is more comfortable when lying down to rest.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
