DETAILED DESCRIPTION
[0038] Here, the technical solutions in the embodiments (or "implementations") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0039] If there are terms related to directional indications or positional relationships in the embodiments of this application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first" and "second" in the embodiments of this application are only used for the purpose of convenience of description and should not be understood as indicating or implying relative importance.
[0040] like Figures 1 to 5 As shown, the chair of the present application includes a seat back 1, a seat cushion 2, a foot support 3, a fixing frame 4, and a locking member 5. The seat back 1 is hinged to the seat cushion 2, which is hinged to the foot support 3, allowing the seat back 1 to fold toward the seat cushion 2, and the seat cushion 2 to fold toward the foot support 3. The foot support 3 supports the seat cushion 2 and is hinged to the fixing frame 4. The locking member 5 is used to lock the seat cushion 2 to limit its displacement.
[0041] In some embodiments, the support frame 3 includes a first hinge end 31 and a second hinge end 32. The first hinge end 31 is hinged to the seat cushion 2, and the second hinge end 32 faces away from the seat cushion 2 and is hinged to the fixing frame 4.
[0042] The seat includes an unfolded state and a folded state. When the seat is in the unfolded state, the second hinge end 32 protrudes forward from the seat cushion 2 along the front-to-back direction of the seat, and the second hinge end 32 is located in front of and below the first hinge end 31. The footrest 3 abuts the seat cushion 2, and the angle between the footrest 3 and the seat cushion 2 is an obtuse angle. This arrangement allows the footrest 3 to support the seat and limit the downward movement of the seat. At the same time, when the seat is in the unfolded state, the front side of the seat cushion 2 is higher than the back side of the seat cushion 2, the first hinge end 31 is connected to the front side of the seat cushion 2, and the lock 5 is connected to the back side of the seat cushion 2.
[0043] When the seat is in the folded state, the backrest 1 is folded against the seat cushion 2, the seat cushion 2 is folded against the leg support 3, and the seat cushion 2 does not exceed the second hinge end 32 in the front-to-rear direction of the seat. Specifically, the rear end of the seat cushion 2 is flush with the second hinge end 32 or is located in front of the second hinge end 32. In this way, when the seat is folded, the backrest 1 and the seat cushion 2 can move forward, reducing the overall space occupied by the seat and increasing the space at the rear of the seat, thereby improving the convenience of using the seat.
[0044] Further in combination Figures 6 to 9 As shown, the folded state of the seat includes a first folded state, a second folded state, and a third folded state. When the seat is in the first folded state, the backrest 1 is folded against the seat cushion 2.
[0045] When the seat is in the second folded state, the backrest 1 is rotated with the seat cushion 2 and the leg support 3 about the second hinge end 32, and the rotation angle is not more than 90 degrees. Preferably, the backrest 1 is rotated with the seat cushion 2 and the leg support 3 about the second hinge end 32 by an angle of 60 degrees. In this way, space is provided for the next folding action of the seat, while avoiding interference between the backrest 1 and other components when the seat is in the second folded state.
[0046] The backrest 1, the seat cushion 2, and the leg support 3 are relatively stationary during the rotation, i.e., the backrest 1, the seat cushion 2, and the leg support 3 move synchronously. The direction of rotation of the backrest 1, the seat cushion 2, and the leg support 3 about the second hinge end 32 is the same as the direction of rotation of the backrest 1 relative to the seat cushion 2 when the seat is in the first folded state.
[0047] When the seat is in the second folded state, the backrest 1 is in a forward-leaning state with the seat cushion 2, and the rear side of the seat cushion 2 is approximately at the highest point of the seat cushion 2, and the first hinge end 31 is approximately directly above the second hinge end 32.
[0048] When the seat is in the third folded state, the backrest 1 is rotated with the seat cushion 2 about the first hinge end 31, and the seat cushion 2 is folded against the leg support 3. During this process, the backrest 1 and the seat cushion 2 move synchronously, and the direction of rotation of the backrest 1 and the seat cushion 2 about the first hinge end 31 is opposite to the direction of rotation of the backrest 1 relative to the seat cushion 2 when the seat is in the first folded state. The seat cushion 2 is folded towards the leg support 3 until it is in close contact with the leg support 3, so as to reduce the volume of the seat after folding and thereby reduce the space occupied.
[0049] The rotation angle of the backrest 1 and the seat cushion 2 about the first hinge end 31 is not more than 150 degrees. Preferably, the rotation angle of the backrest 1 and the seat cushion 2 about the first hinge end 31 is 130 degrees. In this way, the seat cushion 2 is folded against the leg support 3, and the volume of the seat after folding is reduced.
[0050] When the seat is in the third folded position, the support leg 3 further rotates about the second hinge end 32, and in the front-to-back direction of the seat, the first hinge end 31 is located in front of the second hinge end 32. While the support leg 3 rotates about the second hinge end 32, the seat back 1, seat cushion 2, and support leg 3 remain relatively stationary during the rotation process, i.e., the seat back 1, seat cushion 2, and support leg 3 move synchronously.
[0051] Furthermore, when the seat is in the third folded position, after the seat cushion 2 is folded against the foot support 3, the foot support 3 rotates about the second hinge end 32. During the process of the seat cushion 2 being folded against the foot support 3, the foot support 3 remains approximately fixed. In the third folded position, the seat is moved forward relative to the position in the unfolded position, thereby increasing the rear space of the seat and improving the convenience of seat use.
[0052] The rotation direction of the foot stand 3 in the third folded state is the same as the rotation direction of the foot stand 3 in the second folded state, and is also the same as the rotation direction of the seat back 1 relative to the seat cushion 2 in the first folded state.
[0053] When the seat is in the third folded position, the rotation angle of the support leg 3 does not exceed 90 degrees. Preferably, the rotation angle of the support leg 3 is 75 degrees. The line connecting the first hinge end 31 and the second hinge end 32 of the support leg 3 is horizontal, and the seat cushion 2 is located above the support leg 3.
[0054] In some other embodiments, when the seat is in the third folding state, the rotation of the seat back 1 and the seat cushion 2 about the first hinge end 31 occurs simultaneously with the rotation of the support leg 3 about the second hinge end 32. Furthermore, the rotation of the seat back 1 and the seat cushion 2 about the first hinge end 31 occurs slightly later than the rotation of the support leg 3 about the second hinge end 32, or the rotation of the support leg 3 about the second hinge end 32 occurs slightly later than the rotation of the seat back 1 and the seat cushion 2 about the first hinge end 31.
[0055] Recombination Figure 1 and Figure 2 As shown, in some embodiments, the support frame 3 includes a first support leg 33 and a second support leg 34 symmetrically arranged. The fixing frame 4 is located between the first support leg 33 and the second support leg 34, and the first support leg 33 and the second support leg 34 move synchronously. The second hinged end 32 is hinged to the fixing frame 4.
[0056] The lock 5 is connected to the rear end of the seat cushion 2 to limit the rotation of the seat cushion 2. Specifically, the lock 5 includes a lock buckle 51 and a lock body 52. The lock body 52 is provided on the seat cushion 2, and the lock body 52 can be engaged with the lock buckle 51.
[0057] In some embodiments, the seat comprises a first rotation shaft 7, a second rotation shaft 8, a third rotation shaft 9, and a plurality of driving members (not shown). The first rotation shaft 7 is connected to the backrest 1 and the seat cushion 2 respectively, and the backrest 1 is rotatable relative to the seat cushion 2 about the first rotation shaft 7. The second rotation shaft 8 is connected to the seat cushion 2 and the first hinged end 31 respectively, and the seat cushion 2 is rotatable relative to the foot support 3 about the second rotation shaft 8. The third rotation shaft 9 is connected to the second hinged end 32 and the fixed frame 4 respectively, and the foot support 3 is rotatable relative to the fixed frame 4 about the third rotation shaft 9.
[0058] The driving members are used to drive the backrest 1, the seat cushion 2, and the foot support 3 to fold and unfold. Further, the driving members are provided in plurality, and are provided in one-to-one correspondence with the first rotation shaft 7, the second rotation shaft 8, and the third rotation shaft 9. The driving members are preferably electric motors.
[0059] In other embodiments, the driving members are provided in one or two, and the driving members control the seat to fold and unfold through a plurality of gear transmission mechanisms.
[0060] Further combining Figures 10 to 12 As shown, the present application also provides a vehicle comprising a controller (not shown), a luggage compartment 6, and the seat as described above. The luggage compartment 6 is located behind the seat in the front-rear direction of the vehicle. The fixed frame 4 and the lock catch 51 are both provided on the floor of the vehicle. The luggage compartment 6 comprises a compartment body 61 and a compartment cover 62 provided on the compartment body 61. When the seat is in the folded state, the compartment cover 62 can be lapped on the backrest 1, so that the compartment cover 62 and the backrest 1 form a flat plane, thereby facilitating the vehicle to carry bulky items or facilitating the user to lie flat in the vehicle for rest.
[0061] In some embodiments, the compartment cover 62 comprises a first compartment cover 621 and a second compartment cover 622 hinged to the first compartment cover 621. The first compartment cover 621 is located between the second compartment cover 622 and the compartment body 61. When the seat is in the folded state, the second compartment cover 622 can be rotatably lapped on the backrest 1, and the first compartment cover 621 is still lapped on the compartment body 61. In this way, the second compartment cover 622 is more convenient to contact the backrest 1, and the second compartment cover 622, the backrest 1, and the first compartment cover 621 form a flat plane.
[0062] In other embodiments, the second compartment cover 622 is slidingly provided on the first compartment cover 621, and when the seat is in the folded state, the second compartment cover 622 slidingly contacts the backrest 1. In this way, the space above the luggage compartment 6 is not too small, the second compartment cover 622 does not interfere, and the convenience of operating the luggage compartment 6 is improved.
[0063] The movement of the second compartment cover 622 can also be controlled by the driving members such as electric motors, thereby improving the convenience of operating the vehicle and enhancing the user's experience.
[0064] The controller of the vehicle can be electrically connected with the seat, and the folding and unfolding actions of the seat can be input through the controller. When people need to carry large-volume objects or temporarily lie down to rest, the seat can be automatically folded through the control of the vehicle system. After the seat is folded, the seat is moved forward relative to the position when the seat is unfolded, so as to improve the internal space of the vehicle, facilitate loading more objects, and improve the comfort of people when lying down. The second hatch 622 is lapped to the seat to form a bearing plane for bearing objects or a simple "bed" to facilitate people to lie down and rest, thereby improving the use experience of people and the market competitiveness of the vehicle.
[0065] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of the present application is not limited to the precise structures described in the above embodiments and shown in the drawings; any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
