[0023] Example 1 The seat with tilting function provided in this application can be used in vehicles or other usage scenarios. See also Figures 1 to 6 As shown, the seat with tilting function provided in this application includes a base 7, a seat body 3, and a drive module; in the left-right direction of the seat body 3, the middle part of the seat body 3 is hinged to the base 7 via a pivot; the length direction of the pivot is the front-back direction of the seat body 3; the drive module includes a drive assembly and a linkage assembly 4; a linkage assembly 4 is provided between the first side of the seat body 3 and the base 7, and / or a linkage assembly 4 is provided between the second side of the seat body 3 and the base 7, and the drive end of the drive assembly is connected to the seat body 3 so that the seat body 3 can swing back and forth around the pivot; the first side and the second side are spaced apart along the left-right direction of the seat body 3.
[0024] Specifically, in the left-right direction of the seat body 3, the middle part of the seat body 3 is hinged to the base 7 through a pivot. The pivot is parallel to the Y-axis of the vehicle and serves as the center of rotation, constraining the seat body 3 to tilt around this axis. Figure 1 The seat body 3 shown in the figure has linkage assemblies 4 on both the left and right sides (i.e., the first and second sides) to connect with the base 7, which can improve the overall support stability. In addition, the linkage assemblies 4 on both sides of the seat body 3 form a double-sided symmetrical four-bar linkage mechanism, which can convert the driving force output by the drive assembly into the rotational motion of the seat body 3, so that the seat body 3 can swing back and forth in the left and right directions.
[0025] Optionally, a linkage assembly 4 is provided on one of the left and right sides of the seat body 3, and the other side of the seat body 3 can be suspended above the base 7 to form a single-sided support structure. This structure can simplify the structure, reduce costs, and is suitable for light-load scenarios.
[0026] The seat with tilt function provided in this application can tilt the car seat in the left and right directions to improve the seat's entertainment, comfort and safety, and meet users' multi-dimensional requirements for car seats.
[0027] In an optional embodiment, the linkage assembly 4 specifically includes a first linkage 1 and a second linkage 2; one end of the first linkage 1 is hinged to the base 7, the other end of the first linkage 1 is hinged to one end of the second linkage 2, and the other end of the second linkage 2 is hinged to the seat body 3; the first linkage 1, the second linkage 2, the seat body 3, and the base 7 form a first planar four-bar linkage.
[0028] In this embodiment, when the first link 1 undergoes angular displacement, the second link 2 and the seat body 3 hinged to it generate corresponding angular displacement. The changes in the angles of each link conform to the linkage relationship of the kinematic closed-loop equation of the four-bar linkage, thus avoiding motion uncertainty caused by elastic deformation, sliding friction or program control errors in the existing structure.
[0029] More specifically, the drive assembly includes a first connecting ear 5 and a drive device; the mounting end of the drive device is hinged to the base 7; the drive end of the drive device is hinged to the first connecting ear 5, and the first connecting ear 5 is connected to the second link 2 of one of the linkage assemblies 4; the drive end of the drive device extends and retracts to drive the first connecting ear 5 to swing around a preset axis; the preset axis is the connecting axis between the second link 2 and the seat body 3; the drive device, the first connecting ear 5, the seat body 3 and the base 7 form a second planar four-bar linkage.
[0030] In this embodiment, the driving device is specifically a lead screw motor 6. One end of the first connecting ear 5 is hinged to the driving end of the lead screw motor 6, and the other end of the first connecting ear 5 is rigidly connected to the second connecting rod 2. The relative positions of the first connecting ear 5 and the second connecting rod 2 are fixed (the included angle between them remains unchanged). The lead screw motor 6, the first connecting ear 5, the seat body 3, and the base 7 form a second planar four-bar linkage, and the second planar four-bar linkage is arranged parallel to the first planar four-bar linkage.
[0031] See Figure 4 As shown, the lead screw motor 6 is connected to the connecting rod assembly 4 on the left side. The figure shows different states of the seat body 3. Figure 4 Figure a shows the horizontal state of the seat body 3. Figure 4 Figure b shows the seat body 3 tilted to the left. Figure 4Figure c shows the seat body 3 tilted to the right. When the lead screw motor 6 shortens, the first connecting lug 5 of the left linkage assembly 4 drives the second link 2 to rotate counterclockwise, and the first link 1 to rotate clockwise, causing the left side of the seat body 3 to lower, while the middle position of the seat body 3 remains unchanged, and the right side of the seat body 3 to rise accordingly. When the lead screw motor 6 extends, the first connecting lug 5 of the left linkage assembly 4 drives the second link 2 to rotate clockwise, and the first link 1 to rotate counterclockwise, causing the left side of the seat body 3 to rise, while the middle position of the seat body 3 remains unchanged, and the right side of the seat body 3 to lower accordingly. This structure allows the seat body 3 to change angles relative to the base 7 within a certain range, providing users with a comfortable seating posture.
[0032] In an optional embodiment, the linkage assembly 4 further includes a connecting rod 8; there are multiple first linkages 1, and the multiple first linkages 1 are spaced apart along the front-rear direction of the seat body 3; there are multiple second linkages 2, and the multiple second linkages 2 are respectively connected to the multiple first linkages 1, and the connecting rod 8 is connected to the end of the multiple second linkages 2 away from the first linkage 1.
[0033] In this embodiment, the combination of multiple first links 1 and multiple second links 2 improves the overall stability and load-bearing capacity of the seat. Each link can share a portion of the load, thereby reducing the stress on a single link. The multiple hinge points formed by the multiple first links 1 and multiple second links 2 provide more support points, ensuring good support for the seat at different angles. Furthermore, the arrangement of the connecting rod 8 ensures that all second links 2 move synchronously, thereby achieving smooth seat adjustment and improving the user experience.
[0034] In an optional embodiment, the first connecting ear 5 is connected to the connecting rod 8, which can increase the contact area of the connection point, thereby improving the strength and stability of the connection.
[0035] In an optional embodiment, a second connecting ear 9 is provided on the first and / or second side of the seat body 3; the second connecting ear 9 is correspondingly provided with the second connecting rod 2 of the connecting rod assembly 4, and the second connecting ear 9 is hinged to the end of the second connecting rod 2 away from the first connecting rod 1. The seat body 3 is hinged to the second connecting rod 2 through the second connecting ear 9, which can increase the contact area of the connection point, thereby improving the strength and stability of the connection.
[0036] In an optional embodiment, a third connecting ear 10 is provided in the middle of the seat body 3, and the third connecting ear 10 is connected to the base 7 via a pivot. The seat body 3 is hinged to the base 7 via the third connecting ear 10, which can increase the contact area of the connection point, thereby improving the strength and stability of the connection.
[0037] Optionally, such as Figure 5As shown in the figure, another installation configuration of the drive unit is illustrated. The figure also shows different states of the seat body 3. Figure 5 Figure a shows the seat body 3 in a horizontal position. Figure 5 Figure b shows the seat body 3 tilted to the left. Figure 5 Figure c shows the seat body 3 tilted to the right. Specifically, the mounting end of the lead screw motor 6 is connected to the connecting rod assembly 4 on the right side. The mounting end of the lead screw motor 6 can be connected to the first connecting rod 1 of the connecting rod assembly 4 on the right side through the fourth connecting lug 11. The mounting end of the lead screw motor 6 is hinged to one end of the fourth connecting lug 11, and the other end of the fourth connecting lug 11 is rigidly connected to the first connecting rod 1. The relative position of the fourth connecting lug 11 and the first connecting rod 1 is fixed (the included angle between them remains unchanged). When the first connecting rod 1 rotates, the lead screw motor 6 rotates accordingly.
[0038] Optionally, such as Figure 6 As shown in the figure, another installation configuration of the drive unit is illustrated. The figure also shows different states of the seat body 3. Figure 6 Figure a shows the seat body 3 in a horizontal position. Figure 6 Figure b shows the seat body 3 tilted to the left. Figure 6 Figure c shows the seat body 3 tilted to the right. Specifically, the drive end of the lead screw motor 6 can be connected to the first link 1 of the left-side linkage assembly 4 via the fifth connecting lug 12. The drive end of the lead screw motor 6 is hinged to one end of the fifth connecting lug 12, and the other end of the fifth connecting lug 12 is rigidly connected to the first link 1. The relative position of the fifth connecting lug 12 and the first link 1 is fixed (the included angle between them remains unchanged). The mounting end of the lead screw motor 6 can be connected to the first link 1 of the right-side linkage assembly 4 via the fourth connecting lug 11. The mounting end of the lead screw motor 6 is hinged to one end of the fourth connecting lug 11, and the other end of the fourth connecting lug 11 is rigidly connected to the first link 1. The relative position of the fourth connecting lug 11 and the first link 1 is fixed (the included angle between them remains unchanged). When the first link 1 rotates, the lead screw motor 6 rotates accordingly.
[0039] The lead screw motor 6 can be driven by a single motor or dual motors, or arranged in parallel or symmetrical arrangements, all of which are included within the scope of this application.
[0040] Example 2 The seat with tilting function in this second embodiment is an improvement on the above embodiments. The technical content disclosed in the above embodiments will not be described again, and the content disclosed in the above embodiments also belongs to the content disclosed in this second embodiment.
[0041] In an optional embodiment, the base 7 includes two longitudinal beams and two transverse beams; the two longitudinal beams are spaced apart along the left-right direction of the seat body 3, and the two transverse beams are spaced apart along the front-back direction of the seat body 3. The two ends of the transverse beams are connected to the two longitudinal beams respectively to form a frame structure; the middle part of the seat body 3 is hinged to the middle part of the two transverse beams, the first side is hinged to one end of the two transverse beams, and the second side is hinged to the other end of the two transverse beams.
[0042] In this embodiment, a frame structure is formed by two longitudinal beams and two transverse beams, which enhances the overall rigidity of the base 7 and improves the overall stability of the seat. The frame structure can evenly distribute the load applied to the seat body 3, avoid local overload, and extend the service life of the seat.
[0043] Example 3 This application provides a vehicle in embodiment three, which includes a seat with a tilting function as described in any of the above embodiments. Therefore, all the beneficial technical effects of the seat with a tilting function as described in any of the above embodiments will not be repeated here.
[0044] In an optional embodiment, the vehicle also includes a controller; the controller is communicatively connected to the drive components to control the movement of the drive components, thereby driving the seat body 3 to tilt in a specific scenario, which can improve the entertainment, comfort and safety of the ride.
[0045] Specifically, in terms of entertainment, buttons that communicate with the controller can be set up so that passengers can control the seat body 3 to tilt to the left or right by pressing the buttons, thereby increasing the fun and entertainment of riding.
[0046] In terms of comfort, with traditional car seats, when a car turns, the occupants experience centrifugal force in the opposite direction of the turn due to inertia, pushing them in that direction. The occupants can only maintain balance by adjusting their seating position, affecting their comfort. The seat with a tilt function provided in this application improves occupant comfort when the car turns by raising the left or right side of the seat body 3. For example, when the vehicle turns left, the lead screw motor 6 receives a control signal from the controller and adjusts the seat body 3 to a raised right side. This allows the horizontal component of the supporting force exerted by the seat body 3 on the occupants to partially balance the centrifugal force, reducing its impact and improving comfort. The same principle applies when the vehicle turns right, and will not be elaborated further.
[0047] In terms of safety, traditional car seats directly transmit the impact to the occupants during lateral collisions, causing injury. The tilting seat provided in this application reduces the impact on occupants by raising either the left or right side of the seat body 3. For example, when the vehicle is impacted from the left, the lead screw motor 6 receives a control signal from the controller and adjusts the seat body 3 to a tilted-left position. This tilt increases the contact area with the impact, allowing the seat body 3 to absorb some of the impact energy instead of the occupants. Simultaneously, the seat body 3 tilts the occupants to the right, further reducing their impact and improving safety. The same principle applies when the vehicle is impacted from the right, and will not be elaborated further here.
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application 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 therein; 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 this application. In addition, those skilled in the art can understand that although some embodiments herein include certain features included in other embodiments but not other features, combinations of features from different embodiments are meant to be within the scope of this application and form different embodiments.
