Technical Field

[0001] The present invention relates to the technical field of automobiles, and in particular to a seat assembly and an automobile. Background Art

[0002] With the rise of the multi-scene concept of automobiles, the car cabin is no longer just a driving and riding space; it must also rapidly adapt its functions to different scenarios. Traditional fixed car seats are difficult to meet the diverse needs of various scenarios, and fixed seats cannot be quickly adjusted to create a suitable cabin layout. To address this, folding seats have emerged.

[0008] In an optional embodiment, the sliding member is slidingly connected to the support structure, and the backrest structure is rotatably connected to the sliding member. The backrest structure can rotate relative to the sliding member to adjust the inclination angle of the backrest structure relative to the support structure, and the backrest structure can maintain a fixed position after rotating relative to the sliding member.

[0009] In an optional embodiment, the seat assembly further comprises a backrest driving structure, wherein an output end of the backrest driving structure is connected to the backrest structure for driving the backrest structure to rotate relative to the sliding member.

[0010] In an optional embodiment, the sliding member is slidably connected to the support structure via a sliding structure, and the sliding structure includes an upper sliding rail and a lower sliding rail. The upper sliding rail is fixedly connected to the sliding member, and the lower sliding rail is fixed on the support structure. The upper sliding rail and the lower sliding rail are vertically slidably connected.

[0011] In an optional embodiment, the seat assembly further comprises a sliding drive structure, an output end of which is connected to the backrest structure for driving the backrest structure to move vertically relative to the support structure.

[0012] In an optional embodiment, the seat assembly further includes a seat cushion driving structure, an output end of which is connected to the seat cushion structure for driving the seat cushion structure to rotate relative to the backrest structure.

[0013] In an optional embodiment, the seat assembly further includes a command module and a control module, the command module is connected to the control module, and the control module is connected to the seat cushion drive structure; The instruction module is used to send a folding instruction or an unfolding instruction to the control module, and the control module is used to receive the instruction information sent by the instruction module, and when receiving the folding instruction, control the output end of the seat cushion drive structure to move in a first direction to drive the seat cushion structure to rotate to fold on one side of the backrest structure, and when receiving the unfolding instruction, control the output end of the seat cushion drive structure to move in a second direction to drive the seat cushion structure to rotate to form an angle with the backrest structure.

[0014] In an optional embodiment, the seat assembly further includes a detection module, the detection module being connected to the control module, the detection module being configured to detect a rotation angle of the seat cushion structure and transmit the detected angle information to the control module; The control module is used to receive the angle information sent by the detection module, and judge whether there is an abnormality in the rotation process of the seat cushion structure based on the angle information and the output stroke of the seat cushion drive structure; and the control module can control the seat cushion drive structure to close when it is judged that there is an abnormality in the rotation process of the seat cushion structure.

[0015] In a second aspect, the present invention provides a vehicle comprising the seat assembly according to any one of the aforementioned embodiments.

[0016] The seat assembly provided by the present invention includes a cushion structure, a backrest structure, and a support structure; the backrest structure is vertically slidably connected to the support structure, and the cushion structure is rotatably connected to one side of the backrest structure; the cushion structure is used to rotate relative to the backrest structure to be set at an angle with the backrest structure or folded to one side of the backrest structure, and the cushion structure can remain in a fixed position when set at an angle with the backrest structure; the backrest structure is used to drive the cushion structure folded to one side thereof to move vertically relative to the support structure, and the backrest structure can remain in a fixed position when sliding to the highest point. The seat assembly provided by the present invention is applied to an automobile. During normal use of the seat assembly, the backrest structure can be slid to the highest point, and the cushion structure can be rotated to be set at an angle with the backrest structure. Since the backrest structure can remain in a fixed position when sliding to the highest point and the cushion structure can remain in a fixed position when set at an angle with the backrest structure, the cushion structure and the backrest structure can support the human body at this time. When the seat cushion structure and the backrest structure are arranged at an angle, the angle between the seat cushion structure and the backrest structure must meet the seating requirements of the human body. Specifically, the angle can be a right angle or a nearly right angle. Accordingly, the seat cushion structure can be in a horizontal or nearly horizontal state, and the backrest structure can be in a vertical or nearly vertical state. When the seat assembly needs to be folded, the seat cushion structure can first be rotated to fold against the side of the backrest structure, and then the backrest structure can be moved downward on the support structure. When the backrest structure slides to the lowest point, the backrest structure and the seat cushion structure are both folded against the side of the support structure, and the seat assembly as a whole folds and sinks. It can be seen that compared to the folding method of the prior art in which the backrest is folded above the seat cushion, the seat assembly of the present invention folds the seat cushion structure against the side of the backrest structure before sinking the entire seat assembly. This fully utilizes the vertical space within the vehicle and releases all the space occupied by the seat assembly during normal use, achieving the purpose of efficient use of the vehicle interior space and flexible switching between usage scenarios.

[0017] Compared with the prior art, the seat assembly provided by the present invention can realize the folding and sinking of the seat assembly by rotating the cushion structure to fold it to one side of the backrest structure, and then allowing the backrest structure to drive the cushion structure to move downward relative to the support structure, thereby releasing all the space occupied by the seat assembly during normal use, and effectively improving the utilization rate of the space in the vehicle.

DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0024] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0025] Example: like Figures 1-6 As shown, the seat assembly provided in this embodiment includes a cushion structure 1, a backrest structure 2 and a support structure 3; the backrest structure 2 is vertically slidably connected to the support structure 3, and the cushion structure 1 is rotatably connected to one side of the backrest structure 2; the cushion structure 1 is used to rotate relative to the backrest structure 2 to be set at an angle to the backrest structure 2 or folded to one side of the backrest structure 2, and the cushion structure 1 can remain in a fixed position when it is set at an angle to the backrest structure 2; the backrest structure 2 is used to drive the cushion structure 1 folded on one side thereof to move vertically relative to the support structure 3, and the backrest structure 2 can remain in a fixed position when sliding to the highest point.

[0026] The seat assembly provided in this embodiment is applied to a car. When the seat assembly is used normally, Figure 1 and Figure 4 As shown, the backrest structure 2 can be slid to the highest point, and the cushion structure 1 can be rotated to form an angle with the backrest structure 2. Since the backrest structure 2 can maintain a fixed position when sliding to the highest point and the cushion structure 1 can maintain a fixed position when forming an angle with the backrest structure 2, the cushion structure 1 and the backrest structure 2 can support the human body at this time.

[0027] It should be noted that when the seat cushion structure 1 and the backrest structure 2 are arranged at an angle, the angle between the seat cushion structure 1 and the backrest structure 2 must meet the sitting needs of the human body. Specifically, the angle can be a right angle or an approximate right angle. Accordingly, at this time, the seat cushion structure 1 can be in a horizontal state or an approximate horizontal state, and the backrest structure 2 can be in a vertical state or an approximate vertical state.

[0028] When the seat assembly needs to be folded, such as Figure 5 As shown, the seat cushion structure 1 can be rotated to fold on one side of the backrest structure 2, and then Figure 6 As shown, the backrest structure 2 moves downward on the support structure 3. When the backrest structure 2 slides to the lowest point, the backrest structure 2 and the cushion structure 1 are both folded on one side of the support structure 3. At this time, the seat assembly is folded and sunk as a whole.

[0029] It can be seen that compared with the folding method of folding the backrest above the seat cushion in the prior art, the seat assembly of this embodiment folds the seat cushion structure 1 to one side of the backrest structure 2 and then sinks it as a whole, so as to make full use of the vertical space in the car and release all the space occupied by the seat assembly under normal use, thereby achieving the purpose of efficient use of the space in the car and flexible switching of usage scenarios.

[0030] Compared with the prior art, the seat assembly provided in this embodiment can realize the folding and sinking of the seat assembly by rotating the cushion structure 1 to fold it on one side of the backrest structure 2, and then allowing the backrest structure 2 to drive the cushion structure 1 to move downward relative to the support structure 3, thereby releasing all the space occupied by the seat assembly during normal use, and effectively improving the utilization rate of the space in the vehicle.

[0031] In this embodiment, the support structure 3 can be fixed to the vehicle floor or to a groove defined in the floor. The support structure 3 is used to provide enhanced and stable support for the backrest structure 2 and the seat cushion structure 1. The support structure 3 can be provided with hollow holes to achieve a lightweight design. The material of the support structure 3 can be selected to have sufficient strength and durability to withstand the various loads of the seat assembly during folding, sinking, and normal use.

[0032] like Figure 3 As shown, the support structure 3 may include a back panel and a bottom panel. The back panel is vertically arranged and slidably connected to the backrest structure 2; the bottom panel is vertically fixed to the side of the back panel near the backrest structure 2. When the backrest structure 2 and the seat cushion structure 1 are both folded to one side of the support structure 3, the bottoms of the backrest structure 2 and the seat cushion structure 1 can abut against the top of the bottom panel. At this time, the bottom panel supports the backrest structure 2 and the seat cushion structure 1, effectively improving the stability of the backrest structure 2 and the seat cushion structure 1 in the folded and sunken state.

[0033] Furthermore, a side plate can be provided between the bottom plate and the back plate of the support structure 3 to form a groove on the side of the support structure 3 close to the backrest structure 2. When the backrest structure 2 and the cushion structure 1 are both folded to one side of the support structure 3, the backrest structure 2 and the cushion structure 1 are located in the groove. At this time, the support structure 3 can further improve the stability of the backrest structure 2 and the cushion structure 1 in the folded and sunken state.

[0034] like Figure 1 and Figure 2 As shown, the seat assembly provided in this embodiment further includes a sliding member 4 , and the backrest structure 2 is slidably connected to the support structure 3 via the sliding member 4 .

[0035] The sliding member 4 can be fixedly connected to the backrest structure 2 . The sliding member 4 is used to achieve a sliding connection between the backrest structure 2 and the support structure 3 , thereby improving the stability of the sliding process between the backrest structure 2 and the support structure 3 .

[0036] Further, such as Figure 1 and Figure 2 As shown, the sliding member 4 is slidingly connected to the support structure 3, and the backrest structure 2 is rotationally connected to the sliding member 4. The backrest structure 2 can rotate relative to the sliding member 4 to adjust the inclination angle of the backrest structure 2 relative to the support structure 3, and the backrest structure 2 can maintain a fixed position after rotating relative to the sliding member 4.

[0037] When the backrest structure 2 is rotatably connected to the sliding member 4, the backrest structure 2 can rotate relative to the support structure 3, thereby realizing the adjustment of the inclination angle of the backrest structure 2 relative to the support structure 3. At this time, the inclination angle of the backrest structure 2 relative to the vertical plane can also be adjusted, which can meet the human body's different inclination angle requirements for the backrest structure 2.

[0038] like Figure 1 and Figure 2 As shown, the seat assembly further includes a backrest driving structure 5 , the output end of which is connected to the backrest structure 2 for driving the backrest structure 2 to rotate relative to the sliding member 4 .

[0039] Compared with manually driving the backrest structure 2 to rotate, the backrest driving structure 5 can not only save manpower, but also improve the stability of the rotation process of the backrest structure 2.

[0040] In addition, when the seat assembly also includes a backrest drive structure 5, the rotation angle of the backrest structure 2 can be adjusted by controlling the output stroke of the backrest drive structure 5, and the backrest structure 2 can be ensured to remain in a fixed position after rotating relative to the sliding member 4.

[0041] Further, such as Figure 1 and Figure 2 As shown, the backrest drive structure 5 may include a backrest rotation driver 50 and a backrest transmission mechanism 51; the backrest structure 2 and the sliding member 4 are rotationally connected via a backrest shaft, the backrest transmission mechanism 51 is connected to the backrest shaft, and the output end of the backrest rotation driver 50 is connected to the backrest transmission mechanism 51; the backrest rotation driver 50 is used to drive the backrest structure 2 to rotate relative to the sliding member 4 via the backrest transmission mechanism 51 and the backrest shaft.

[0042] The backrest rotation driver 50 may be a rotation driver such as a motor, and the backrest transmission mechanism 51 may be a recliner including gears.

[0043] like Figure 1-Figure 3 As shown, the sliding member 4 is slidably connected to the support structure 3 through the sliding structure 6. The sliding structure 6 includes an upper sliding rail 60 and a lower sliding rail 61. The upper sliding rail 60 is fixedly connected to the sliding member 4, and the lower sliding rail 61 is fixed on the support structure 3. The upper sliding rail 60 and the lower sliding rail 61 are vertically slidably connected.

[0044] The upper slide rail 60 can be fixed vertically on one side of the sliding member 4, and the lower slide rail 61 can be fixed vertically on the support structure 3. The lower slide rail 61 serves as a fixed part of the sliding structure 6 and is used to provide a guide for vertical movement of the upper slide rail 60 during the sliding process.

[0045] To further enhance the stability of the sliding structure 6 during sliding, at least the lower rail 61 of the upper rail 60 and the lower rail 61 is groove-shaped, with the upper rail 60 slidingly connected within the groove of the lower rail 61. When the upper rail 60 is also groove-shaped, to enhance the overall structural strength, appearance, and smoothness of the slide structure, the notch of the upper rail 60 can be inserted into the groove of the lower rail 61, with the spaces within the grooves of the upper rail 60 and the lower rail 61 being butted together to form a cavity.

[0046] As shown in the figure, the seat assembly further includes a sliding drive structure 7 , the output end of which is connected to the backrest structure 2 for driving the backrest structure 2 to move vertically relative to the support structure 3 .

[0047] Compared with manpower to drive the backrest structure 2 to move vertically or relying on gravity to achieve automatic downward movement of the backrest structure 2, the sliding drive structure 7 can save manpower and improve the reliability and stability of the vertical movement process of the backrest structure 2.

[0048] In addition, the vertical movement position of the backrest structure 2 can be adjusted by controlling the output stroke of the sliding drive structure 7, so that the vertical movement process of the backrest structure 2 is adjustable and safer.

[0049] Among them, the sliding drive structure 7 can adopt a telescopic drive such as an electric push rod. Figure 1 and Figure 2 As shown, the preferred sliding drive structure 7 of this embodiment includes a slide motor 70, a screw rod 71, a nut and a worm gear transmission mechanism. One end of the screw rod 71 is fixedly connected to the upper slide rail 60, and the nut is threadedly sleeved on the outside of the screw rod 71. The slide motor 70 is fixed on the bracket structure 3, and the output end of the slide motor 70 and the nut are connected through a worm gear transmission mechanism; the slide motor 70 is used to drive the nut to rotate through the worm gear transmission mechanism, thereby driving the screw rod 71 to rotate and move vertically at the same time. When the screw rod moves vertically, it can drive the upper slide rail 60 to move vertically, thereby realizing the vertical movement of the backrest structure 2, ensuring the stability of the backrest structure 2 during the sinking process after folding.

[0050] In this embodiment, if Figure 1 and Figure 2 As shown, the seat assembly further includes a seat cushion driving structure 8 , the output end of which is connected to the seat cushion structure 1 for driving the seat cushion structure 1 to rotate relative to the backrest structure 2 .

[0051] Compared to manually driving the seat cushion structure 1 to rotate, the seat cushion drive structure 8 not only saves manpower but also improves the smoothness of the seat cushion structure 1's rotation process. Furthermore, this embodiment can adjust the seat cushion structure 1's rotation angle by controlling the output stroke of the seat cushion drive structure 8, ensuring that the seat cushion structure 1 remains fixed in position after rotation, thereby ensuring that the seat cushion structure 1 remains fixed in position when it is arranged at an angle to the backrest structure 2.

[0052] Among them, the seat cushion drive structure 8 can include a seat cushion rotation driver 80 and a seat cushion transmission mechanism 81; the seat cushion structure 1 and the backrest structure 2 are rotationally connected through the seat cushion shaft, the seat cushion transmission mechanism 81 is connected to the seat cushion shaft, and the output end of the seat cushion rotation driver 80 is connected to the seat cushion transmission mechanism 81; the seat cushion rotation driver 80 is used to drive the seat cushion structure 1 to rotate relative to the backrest structure 2 through the seat cushion transmission mechanism 81 and the seat cushion shaft.

[0053] Furthermore, the seat cushion rotation driver 80 may also be a rotation driver such as a motor, and the seat cushion transmission mechanism 81 may also be a recliner including gears.

[0054] When the seat assembly provided in this embodiment includes a backrest drive structure 5, a sliding drive structure 7 and a seat cushion drive structure 8, during the process of folding the seat assembly, the backrest drive structure 5 and the seat cushion drive structure 8 can first be used to drive the backrest and the seat cushion to rotate in opposite directions, so that the backrest and the seat cushion are both rotated to a vertical state, and then driven by the sliding drive structure 7, they sink vertically together, thereby releasing all the space occupied by the seat assembly during normal use, thereby achieving the purpose of improving space utilization and flexible scene switching.

[0055] The seat assembly provided in this embodiment may further include a command module and a control module, the command module being connected to the control module, and the control module being connected to the seat cushion drive structure 8; the command module being used to send a folding command or an unfolding command to the control module, the control module being used to receive the command information sent by the command module, and controlling the output end of the seat cushion drive structure 8 to move in a first direction upon receiving the folding command, so as to drive the seat cushion structure 1 to rotate to a side folded on the backrest structure 2, and controlling the output end of the seat cushion drive structure 8 to move in a second direction upon receiving the unfolding command, so as to drive the seat cushion structure 1 to rotate to an angle with the backrest structure 2.

[0056] The first direction and the second direction are opposite. When the seat driving structure 8 includes a rotary driver, the first direction may be counterclockwise, and correspondingly, the second direction is clockwise.

[0057] In this embodiment, the command module may be a physical button, a touch screen or a voice control interface preset on the car, and the control module may be the car's onboard system.

[0058] The backrest drive mechanism 5 and the sliding drive mechanism 7 provided in this embodiment can both be connected to a control module. When the seat assembly needs to be folded, the user first issues a folding command via a physical button, touch screen, or smart terminal in the vehicle. The control module receives the folding command, converts it into an electrical signal, and transmits it to the seat cushion drive mechanism 8, the backrest drive mechanism 5, and the sliding drive mechanism 7. The seat cushion drive mechanism 8 then drives the seat cushion structure 1 to rotate until it folds against the side of the backrest structure 2. The backrest drive mechanism 5 drives the backrest structure 2 to rotate to a vertical position. At this point, the backrest structure 2 and the seat cushion structure 1 rotate in opposite directions until they are both in a vertical or nearly vertical position. The sliding drive mechanism 7 then drives the upper rail 60 of the slide rail structure downward, thereby causing the backrest structure 2 and seat cushion structure 1 to sink. During the sinking process, the lower rail 61 of the slide rail structure provides a smooth guide to prevent the seat assembly from shaking or shifting. When the seat assembly is folded and stored to the target position (i.e., the backrest structure 2 and seat cushion structure 1 are both folded against one side of the support structure 3), the seat cushion drive mechanism, the backrest drive mechanism 5, and the sliding drive mechanism 7 all stop operating.

[0059] To deploy the seat assembly, the user first issues a deployment command via a physical button, touchscreen, or smart terminal inside the vehicle. The control module receives the deployment command, converts it into an electrical signal, and transmits it to the seat cushion drive mechanism 8, the backrest drive mechanism 5, and the sliding drive mechanism 7. The sliding drive mechanism 7 then drives the upper rail 60 of the slide rail structure upward, thereby lifting the backrest structure 2 and the seat cushion structure 1. When the backrest structure 2 and the seat cushion structure 1 reach their target positions (typically the highest point of the backrest structure 2's sliding travel), the seat cushion drive mechanism 8 and the backrest drive mechanism 5 drive the seat cushion structure 1 and the backrest structure 2 to rotate in opposite directions, deploying the seat cushion structure 1 to a horizontal or nearly horizontal position and the backrest structure 2 to a specified angle to meet the user's seating requirements. At this point, the seat cushion structure 1 and the backrest structure 2 are typically arranged at an obtuse angle. When the backrest structure 2's ground clearance, the backrest structure 2's rotation angle, and the seat cushion structure 1's rotation angle all reach their target positions, the seat cushion drive mechanism, the backrest drive mechanism 5, and the sliding drive mechanism 7 all cease operation.

[0060] It can be seen that this embodiment adopts a command module and a control module, so that the user can activate the folding or unfolding function of the seat assembly by simply pressing a physical button, touching the touch screen or voice control, which effectively improves the operating convenience of the seat assembly.

[0061] Furthermore, the seat assembly also includes a detection module, which is connected to the control module, and the detection module is used to detect the rotation angle of the cushion structure 1 and send the detected angle information to the control module; the control module is used to receive the angle information sent by the detection module, and based on the angle information and the output stroke of the cushion drive structure 8, determine whether there is an abnormality in the rotation process of the cushion structure 1; and the control module can control the cushion drive structure 8 to shut down when it is determined that there is an abnormality in the rotation process of the cushion structure 1.

[0062] The detection module may include a seat cushion angle sensor, which is used to detect the rotation angle of the seat cushion structure 1. Furthermore, the detection module may include a backrest angle sensor and a distance sensor, the backrest angle sensor being used to detect the rotation angle of the backrest structure 2, and the distance sensor being used to detect the sinking position of the backrest structure 2. In this case, the backrest angle sensor and the distance sensor may also respectively send the information they detect to the control module. After receiving the information sent by the backrest angle sensor and the distance sensor, the control module may also determine whether there is any abnormality in the rotation process and the sinking process of the backrest based on this information and the output stroke of the backrest structure 2 and the output stroke of the sliding drive structure 7, and control the backrest structure 2 and the sliding drive structure 7 to close if it is determined that there is an abnormality.

[0063] The abnormal situation refers to a situation where the value detected by the sensor does not match the output stroke of the driving structure corresponding to the sensor.

[0064] It can be seen that this embodiment can also monitor the folding angle and sinking position of the seat assembly in real time by setting up a detection module, and promptly control each driving structure to stop operation in time when abnormal situations occur in the folding and sinking process of the seat assembly to ensure safe use.

[0065] This embodiment also provides a car, which includes the above-mentioned seat assembly. Therefore, the car and the above-mentioned seat assembly can solve the same technical problems and achieve the same technical effects, which will not be described in detail here.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
