Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a seat assembly and an automobile. Background Technology

[0002] With the rise of the multi-scenario concept in automobiles, the car cabin is no longer just a driving and riding space, but also needs to quickly transform its function in different scenarios. The fixed form of traditional car seats cannot meet the diverse needs of different scenarios, and fixed seats cannot be quickly adjusted to a suitable cabin layout. Based on this, folding seats have emerged.

[0003] Existing folding seats typically consist of a base frame, a seat cushion, and a backrest. The base frame is fixed to the vehicle floor, the seat cushion is fixed to the base frame, and the backrest is hinged to one side of the seat cushion. The folding process of this folding seat is achieved by rotating the backrest forward, causing the backrest to fold over the seat cushion.

[0004] However, the existing folding seats still do not provide enough interior space when folded, making it difficult to maximize the use of interior space. Summary of the Invention

[0005] The purpose of this invention is to provide a seat assembly and a car to alleviate the technical problem in the prior art where the folding process of a car folding seat is achieved by rotating the backrest forward so that the backrest folds over the seat cushion, but the folding seat still does not provide enough space in the car interior after folding, making it difficult to maximize the use of the interior space.

[0006] In a first aspect, the present invention provides a seat assembly, the seat assembly comprising a seat cushion structure, a backrest structure, and a support structure; The backrest structure and the support structure are slidably connected vertically, and the seat cushion structure is rotatably connected to one side of the backrest structure; the seat cushion structure is used to rotate relative to the backrest structure so as to be set at an angle to the backrest structure or folded to one side of the backrest structure, and the seat cushion structure can maintain a fixed position when set at an angle to the backrest structure. The backrest structure is used to drive the seat cushion structure folded to one side to move vertically relative to the support structure, and the backrest structure can maintain a fixed position when it slides to the highest point.

[0007] In an optional embodiment, the seat assembly further includes a slider, through which the backrest structure is slidably connected to the support structure.

[0008] In an optional embodiment, the sliding member is slidably 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 tilt 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 includes a backrest drive structure, the output end of which 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 and the support structure are slidably connected by a sliding structure, the sliding structure including an upper slide rail and a lower slide rail, the upper slide rail being fixedly connected to the sliding member, the lower slide rail being fixed to the support structure, and the upper slide rail and the lower slide rail being slidably connected vertically.

[0011] In an optional embodiment, the seat assembly further includes a sliding drive structure, the 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 drive structure, the 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 an instruction module and a control module, the instruction module being connected to the control module, and the control module being connected to the seat cushion drive structure; The instruction module is used to send folding or unfolding instructions to the control module. The control module is used to receive 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 along a first direction to drive the seat cushion structure to rotate to one side of the backrest structure. When receiving the unfolding instruction, control the output end of the seat cushion drive structure to move along a second direction to drive the seat cushion structure to rotate to an angle with the backrest structure.

[0014] In an optional embodiment, the seat assembly further includes a detection module connected to the control module, the detection module being used to detect the rotation angle of the seat cushion structure and send the detected angle information to the control module; The control module is used to receive angle information sent by the detection module, and to determine whether the rotation process of the seat cushion structure is abnormal 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 shut down when it is determined that the rotation process of the seat cushion structure is abnormal.

[0015] In a second aspect, the present invention provides an automobile, the automobile including the seat assembly described in any of the foregoing embodiments.

[0016] The seat assembly provided by this invention includes a seat cushion structure, a backrest structure, and a support structure. The backrest structure and the support structure are slidably connected vertically, and the seat cushion structure is rotatably connected to one side of the backrest structure. The seat cushion structure is used to rotate relative to the backrest structure to be angled to the backrest structure or folded to one side of the backrest structure, and the seat cushion structure can maintain a fixed position when angled to the backrest structure. The backrest structure is used to drive the seat cushion structure folded to one side to move vertically relative to the support structure, and the backrest structure can maintain a fixed position when sliding to its highest point. The seat assembly provided by this invention is applied to automobiles. When using the seat assembly normally, the backrest structure can be slid to its highest point, and the seat cushion structure can be rotated to be angled to the backrest structure. Since the backrest structure can maintain a fixed position when sliding to its highest point, and the seat cushion structure can maintain a fixed position when angled to the backrest structure, the seat cushion structure and the backrest structure can support the human body at this time. When the seat cushion structure and backrest structure are set at an angle, the angle between them must meet the needs of human seating. Specifically, this angle can be a right angle or a near-right angle. Correspondingly, the seat cushion structure can be in a horizontal or near-horizontal state, while the backrest structure can be in a vertical or near-vertical state. When the seat assembly needs to be folded, the seat cushion structure can be rotated to fold onto the side of the backrest structure first, and then the backrest structure can be moved downwards on the support structure. When the backrest structure slides to its lowest point, both the backrest structure and the seat cushion structure are folded onto one side of the support structure, at which point the entire seat assembly is folded down. It can be seen that, compared to the existing folding method where the backrest is folded above the seat cushion, the seat assembly of this invention folds the seat cushion structure onto one side of the backrest structure before sinking down as a whole. This fully utilizes the vertical space inside the vehicle, releasing all the space occupied by the seat assembly during normal use, achieving efficient utilization of the vehicle's interior space and flexible switching of usage scenarios.

[0017] Compared with the prior art, the seat assembly provided by the present invention can fold down the seat assembly by rotating the seat cushion structure to one side of the backrest structure, and then causing the backrest structure to move the seat cushion structure downward relative to the support structure. This releases all the space occupied by the seat assembly under normal use and effectively improves the utilization rate of the vehicle interior space.

[0018] The automobile provided by the present invention includes the above-described seat assembly, and thus the automobile has the same beneficial effects as the above-described seat assembly. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0024] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

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

[0026] The seat assembly provided in this embodiment is applied to automobiles. When using the seat assembly normally, such as... Figure 1 and Figure 4 As shown, the backrest structure 2 can be slid to the highest point, and the seat 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 it is slid to the highest point, and the seat cushion structure 1 can maintain a fixed position when it is set at an angle with the backrest structure 2, the seat 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 set at an angle, the angle between the seat cushion structure 1 and the backrest structure 2 must meet the needs of human seating. Specifically, the angle can be a right angle or an approximately right angle. Correspondingly, the seat cushion structure 1 can be in a horizontal or approximately horizontal state, while the backrest structure 2 can be in a vertical or approximately vertical state.

[0028] When it is necessary to fold the seat components, such as Figure 5 As shown, the seat cushion structure 1 can be rotated to fold onto 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, both the backrest structure 2 and the seat cushion structure 1 fold to one side of the support structure 3. At this time, the entire seat assembly folds down.

[0029] As can be seen, compared with the existing technology where the backrest is folded over the seat cushion, the seat assembly in this embodiment folds the seat cushion structure 1 to one side of the backrest structure 2 and then lowers it as a whole. This makes full use of the vertical space in the vehicle and releases all the space occupied by the seat assembly under normal use, achieving the purpose of efficient use of the vehicle space and flexible switching of usage scenarios.

[0030] Compared with the prior art, the seat assembly provided in this embodiment can fold down and release the space occupied by the seat cushion structure 1 when it is in normal use, by rotating the seat cushion structure 1 to one side of the backrest structure 2, and then causing the backrest structure 2 to drive the seat cushion structure 1 to move downward relative to the support structure 3. This effectively improves the utilization rate of the vehicle interior space.

[0031] In this embodiment, the support structure 3 can be fixed to the car floor or to a groove in the floor. The support structure 3 is used to provide stable support for the backrest structure 2 and the seat cushion structure 1. The support structure 3 may have perforations to facilitate lightweight design. The material of the support structure 3 can be selected to have sufficient strength and durability so that the support structure 3 can withstand various loads on the seat assembly under folding, sinking, and normal use conditions.

[0032] like Figure 3 As shown, the support structure 3 may include a back plate and a bottom plate. The back plate is vertically arranged and slidably connected to the backrest structure 2; the bottom plate is vertically fixed to the side of the back plate closest to the backrest structure 2. When both the backrest structure 2 and the seat cushion structure 1 are folded to one side of the support structure 3, the bottom of both the backrest structure 2 and the seat cushion structure 1 can abut against the top of the bottom plate. At this time, the bottom plate 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 so that a groove is formed on the side of the support structure 3 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 backrest structure 2 and the seat 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 seat 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 also includes a slider 4, and the backrest structure 2 is slidably connected to the bracket structure 3 through the slider 4.

[0035] The sliding member 4 can be fixedly connected to the backrest structure 2. The sliding member 4 is used to realize the 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] Furthermore, such as Figure 1 and Figure 2 As shown, the sliding member 4 is slidably connected to the support structure 3, and the backrest structure 2 is rotatably connected to the sliding member 4. The backrest structure 2 can rotate relative to the sliding member 4 to adjust the tilt 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 tilt angle of the backrest structure 2 relative to the support structure 3. At this time, the tilt angle of the backrest structure 2 relative to the vertical plane can also be adjusted, which can meet the different tilt angle requirements of the human body for the backrest structure 2.

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

[0039] Compared to manually driving the backrest structure 2 to rotate, the backrest drive 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 kept in a fixed position after rotating relative to the sliding member 4.

[0041] Furthermore, 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 rotatably connected by a backrest rotating shaft, the backrest transmission mechanism 51 is connected to the backrest rotating 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 through the backrest transmission mechanism 51 and the backrest rotating shaft.

[0042] The backrest rotation drive 50 can be a rotary drive such as a motor, and the backrest transmission mechanism 51 can be an angle adjuster including gears.

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

[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 the fixed part of the sliding structure 6 and is used to provide vertical movement guidance for the sliding process of the upper slide rail 60.

[0045] To further improve the stability of the sliding structure 6 during the sliding process, at least the lower slide rail 61 is grooved, and the upper slide rail 60 is slidably connected to the groove of the lower slide rail 61. When the upper slide rail 60 is also grooved, to improve the overall structural strength, appearance neatness, and smoothness of the slide rail structure, the groove of the upper slide rail 60 can be inserted into the groove of the lower slide rail 61, and the spaces inside the grooves of the upper slide rail 60 and the lower slide rail 61 are connected to form a cavity.

[0046] As shown in the figure, the seat assembly also includes a sliding drive structure 7. The output end of the sliding drive structure 7 is connected to the backrest structure 2 and is used to drive the backrest structure 2 to move vertically relative to the support structure 3.

[0047] Compared to manually moving the backrest structure 2 vertically or relying on gravity to automatically move the backrest structure 2 downwards, 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] Furthermore, by controlling the output stroke of the sliding drive structure 7, the vertical movement position of the backrest structure 2 can also be adjusted, thereby making the vertical movement process of the backrest structure 2 adjustable and safer.

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

[0050] In this embodiment, as Figure 1 and Figure 2 As shown, the seat assembly also includes a seat cushion drive structure 8, the output end of which is connected to the seat cushion structure 1 and is used to drive 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 rotation process of the seat cushion structure 1. In addition, this embodiment can also adjust the rotation angle of the seat cushion structure 1 by controlling the output stroke of the seat cushion drive structure 8, and ensure that the seat cushion structure 1 remains in a fixed position after rotation, so that the seat cushion structure 1 remains in a fixed position when it is set at an angle with the backrest structure 2.

[0052] The seat cushion drive structure 8 may 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 rotatably connected by a 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 rotation drive 80 can also be a rotary drive such as a motor, and the seat transmission mechanism 81 can also be an angle adjuster 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 folding process of the seat assembly, the backrest and seat cushion can be driven to rotate in opposite directions by the backrest drive structure 5 and the seat cushion drive structure 8, so that the backrest and seat cushion are rotated to a vertical state. Then, driven by the sliding drive structure 7, they sink together vertically, releasing all the space occupied by the seat assembly under normal use, thereby improving space utilization and allowing for flexible scene switching.

[0055] The seat assembly provided in this embodiment may further include an instruction module and a control module. The instruction module is connected to the control module, and the control module is connected to the seat cushion drive structure 8. The instruction module is used to send folding instructions or unfolding instructions to the control module. The control module is used to receive instruction information sent by the instruction module, and when receiving the folding instruction, it controls the output end of the seat cushion drive structure 8 to move along a first direction to drive the seat cushion structure 1 to rotate to one side of the backrest structure 2. When receiving the unfolding instruction, it controls the output end of the seat cushion drive structure 8 to move along a second direction 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 drive structure 8 includes a rotary driver, the first direction can be counterclockwise, and the corresponding second direction is clockwise.

[0057] In this embodiment, the instruction module can be a preset physical button, touch screen, or voice control interface on the vehicle, while the control module can be the vehicle's infotainment system.

[0058] The backrest drive structure 5 and sliding drive structure 7 provided in this embodiment can both be connected to the control module. When the seat assembly needs to be folded, the user first issues a folding command through a physical button, touch screen, or smart terminal in the vehicle. After receiving the folding command, the control module converts it into an electrical signal and transmits it to the cushion drive structure 8, backrest drive structure 5, and sliding drive structure 7. Then, the cushion drive structure 8 drives the cushion structure 1 to rotate to one side of the backrest structure 2, and the backrest drive structure 5 drives the backrest structure 2 to rotate to a vertical position. At this time, the backrest structure 2 and the cushion structure 1 rotate in opposite directions to both be in a vertical or near-vertical position. Then, the sliding drive structure 7 drives the upper slide rail 60 in the slide rail structure to move downward, thereby causing the backrest structure 2 and the cushion structure 1 to sink. During the sinking process, the lower slide rail 61 in the slide rail structure provides a smooth guiding effect to prevent the seat assembly from shaking or shifting. When the seat assembly is folded and stored to the target state (that is, the backrest structure 2 and the cushion structure 1 are both folded to one side of the bracket structure 3), the cushion drive mechanism, the backrest drive structure 5, and the sliding drive structure 7 all stop working.

[0059] When the seat assembly needs to be unfolded, the user first issues an unfolding command via a physical button, touchscreen, or smart terminal inside the vehicle. Upon receiving the command, the control module converts it into an electrical signal and transmits it to the seat cushion drive structure 8, backrest drive structure 5, and sliding drive structure 7. The sliding drive structure 7 then drives the upper slide rail 60 in the slide rail structure to move upwards, thereby raising the backrest structure 2 and seat cushion structure 1. When the backrest structure 2 and seat cushion structure 1 reach the target position (usually the highest point of the sliding stroke of the backrest structure 2), the seat cushion drive structure 8 and backrest drive structure 5 drive the seat cushion structure 1 and backrest structure 2 to rotate in opposite directions, causing the seat cushion structure 1 to unfold to a horizontal or near-horizontal state, and the backrest structure 2 to unfold to a specified angle to meet the user's seating needs. At this point, the seat cushion structure 1 and backrest structure 2 are typically set at an obtuse angle. Once the height of the backrest structure 2 from the ground, the rotation angle of the backrest structure 2, and the rotation angle of the seat cushion structure 1 all reach the target positions, the seat cushion drive mechanism, backrest drive structure 5, and sliding drive structure 7 all cease operation.

[0060] As can be seen, this embodiment, by employing an instruction module and a control module, enables users to activate the folding or unfolding function of the seat assembly through a simple operation such as pressing a physical button, touching a touch screen, or voice control, effectively improving the ease of operation of the seat assembly.

[0061] Furthermore, the seat assembly also includes a detection module connected to the control module. The detection module is used to detect the rotation angle of the seat 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 determine whether there is an abnormality in the rotation process of the seat cushion structure 1 based on the angle information and the output stroke of the seat cushion drive structure 8. The control module can control the seat cushion drive structure 8 to shut down when it determines that there is an abnormality in the rotation process of the seat 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. Further, the detection module may include a backrest angle sensor and a distance sensor. The backrest angle sensor is used to detect the rotation angle of the backrest structure 2, and the distance sensor is used to detect the sinking position of the backrest structure 2. The backrest angle sensor and the distance sensor can also send their detected information to the control module. After receiving the information from the backrest angle sensor and the distance sensor, the control module can determine whether any abnormalities have occurred in the rotation and sinking processes 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. If an abnormality is detected, the control module will shut down the backrest structure 2 and the sliding drive structure 7.

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

[0064] As can be seen, this embodiment can also monitor the folding angle and sinking position of the seat assembly in real time by setting a detection module, and promptly control each drive structure to stop operating when abnormalities occur during the folding and sinking process of the seat assembly, so as to ensure safe use.

[0065] This embodiment also provides a car that includes the above-described seat assembly. Therefore, the car and the above-described seat assembly can solve the same technical problem and achieve the same technical effect, 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, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions 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.
