Description

Technical Field

[0001] This application relates to the field of automotive technology, specifically to a seat assembly and a vehicle. Background Technology

[0002] As people's quality of life continues to improve, cars have become a common means of transportation, which has spurred the rapid development of the automotive industry. People's demands for car comfort are constantly increasing, and car seats are one of the key components that best reflect car comfort.

[0003] To improve seat comfort, some car seats are equipped with leg rests. These leg rests provide support for passengers' calves, relieving soreness and discomfort caused by prolonged sitting.

[0004] In the existing technology, the overall structure of the seat assembly with leg support mechanism is complicated, and the leg support mechanism is not easy to separate from the rest of the seat assembly, making maintenance inconvenient. Summary of the Invention

[0005] One objective of this invention is to provide a vehicle seat assembly that solves the technical problem in related technologies where the leg support mechanism is not easily separable from the rest of the seat assembly. A second objective is to provide a vehicle.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A vehicle seat assembly is provided for mounting on a vehicle mounting base. The seat assembly includes a seat component and a leg rest component. The seat component is disposed on and connected to the mounting base. The leg rest component is disposed on the mounting base and located on one side of the seat component. The leg rest component includes a mounting bracket and a support component. The mounting bracket is connected to the mounting base. The support component is rotatable relative to the mounting bracket, moving closer to or further away from the mounting bracket.

[0008] Based on the aforementioned technical methods, during the installation of the seat assembly, since both the leg rest component and the seat assembly are mounted on the mounting base, there is no need to consider the assembly issues between them, greatly simplifying the structure of the seat assembly and making its design and manufacturing more convenient. The leg rest component is directly connected to the mounting base via a mounting bracket, and is not connected to the seat assembly. When the leg rest component malfunctions and requires repair or replacement, it can be disassembled by separating the mounting bracket from the mounting base, facilitating repair. After a passenger sits on the seat assembly, the rotation angle of the support component around the mounting bracket can be adjusted to adjust its position, ensuring that the passenger's legs can comfortably rest on the support component, thus alleviating leg fatigue during the journey.

[0009] Furthermore, the mounting base plate has a stepped surface. The stepped surface includes a first mounting surface and a second mounting surface that are interconnected and intersect. The mounting bracket includes mounting components, which include a first mounting plate and a second mounting plate that are interconnected. One end of the first mounting plate is connected to the second mounting plate, forming an angle between them. The first mounting plate is fitted against and connected to the first mounting surface. The second mounting plate is fitted against and connected to the second mounting surface.

[0010] According to the above technical means, since the first mounting surface and the second mounting surface can have a certain angle, the first mounting plate that is attached to the first mounting surface and the second mounting plate that is attached to the second mounting surface can also form a certain angle. In this way, the first mounting plate and the second mounting plate can fix the mounting bracket from different directions, thereby ensuring the stability of the connection between the mounting bracket and the mounting base plate.

[0011] Furthermore, there are two mounting components. The mounting bracket also includes a connector. Along the extension direction of the connector, the two mounting components are located at both ends of the connector and are connected to the connector.

[0012] According to the above technical means, the two mounting components are located at both ends of the mounting bracket, which is composed of two mounting components and a connecting component. The two mounting components can fix the mounting bracket from both ends of the mounting bracket, which can ensure the stability of the connection between the mounting bracket and the mounting base plate.

[0013] Furthermore, the mounting component also includes a fixing plate. One side of the fixing plate is connected to the connector. The first mounting plate and the second mounting plate are located on the side of the fixing plate away from the connector and are connected to the fixing plate.

[0014] Based on the aforementioned technical means, in practical use, the first and second mounting plates, when connected to the fixing plate, form a structure similar to reinforcing ribs. This improves the strength of the first and second mounting plates and prevents deformation. During the installation or disassembly of the mounting bracket, because the first and second mounting plates are located on the side of the fixing plate furthest from the connector, the tools used by workers to disassemble and install the first and second mounting plates will not interfere with the connector, making the disassembly and installation of the mounting bracket easier.

[0015] Furthermore, the connector includes multiple connecting shafts, one end of which is connected to one of the mounting components, and the other end of which is connected to another mounting component.

[0016] Based on the above technical means, multiple connecting shafts can provide support to different positions of the mounting components located at both ends of the connector, thereby ensuring that different positions of the mounting components can be supported, thus improving the stability of the mounting components.

[0017] Furthermore, the mounting component also includes a positioning post. The positioning post is disposed on one of the first mounting plate and the second mounting plate, and is located on the side of the first mounting plate and the second mounting plate that is close to each other. The positioning post passes through the mounting base plate.

[0018] According to the above technical means, as the mounting bracket approaches the mounting base plate, the positioning post can be inserted through the mounting base plate to fix the relative position between the mounting bracket and the mounting base plate, which facilitates the subsequent fixing of the leg support assembly to the mounting base plate.

[0019] Furthermore, the leg support assembly also includes a drive mechanism. The drive mechanism is connected to the mounting bracket and also to the support assembly. The drive mechanism is used to move the support assembly away from or towards the mounting bracket.

[0020] Based on the aforementioned technical means, passengers can adjust the position of the support component by adjusting the drive mechanism, which can fix the support component in a comfortable position and improve passenger comfort.

[0021] Furthermore, the drive mechanism includes a connecting rod, a drive motor, a drive component, an adapter, and a driving component. The connecting rod is connected to the mounting bracket. The drive motor is rotatably connected to the connecting rod. The drive component is connected to the output shaft of the drive motor. The drive motor drives the drive component to slide along the extension direction of the output shaft. The sliding direction of the drive component is perpendicular to the rotation axis of the drive motor. One end of the adapter is rotatably connected to the connecting rod, and the rotation axis of the adapter is parallel to the rotation axis of the drive motor. The other end of the adapter is connected to the support assembly. One end of the driving component is rotatably connected to the drive component, and its rotation axis is parallel to the rotation axis of the drive motor. The other end of the driving component is connected to the adapter and is used to drive the adapter to rotate around the rotation axis.

[0022] According to the above technical means, since the rotation axis of the adapter is parallel to the rotation axis of the drive motor, the movement of the adapter and the drive motor will not interfere with each other during rotation, ensuring normal rotation. After the drive motor starts, it drives the drive component to move along the extension direction of the output shaft. Simultaneously, the drive component, which is rotatably connected to the drive component, moves synchronously. Since one end of the drive component is connected to the adapter, the adapter rotates around its rotation axis under the drive of the drive component. This drives the support assembly to move, achieving position adjustment of the support assembly.

[0023] Furthermore, the drive mechanism also includes two sets of linkage assemblies. Along the rotation axis of the adapter, the two sets of linkage assemblies are located on both sides of the adapter. Each linkage assembly includes a first link, a second link, and a third link. The first link is rotatably connected to the adapter, and one end is rotatably connected to a support assembly. The second link is located on the side of the first link away from the drive motor, with one end rotatably connected to the adapter and the other end rotatably connected to the support assembly. One end of the third link is rotatably connected to the other end of the first link, and the other end is rotatably connected to a connecting rod. The connecting rod is connected to the support assembly via the first and third links. The rotation axes of the first, second, and third links are all parallel to the rotation axis of the drive motor.

[0024] According to the aforementioned technical means, since the first link is rotatably connected to the adapter, it moves synchronously with the adapter. Simultaneously, because one end of the third link is rotatably connected to the other end of the first link, and the other end is rotatably connected to the connecting rod, the movement of the first link is restricted by the third link. At this time, the third link rotates counterclockwise, and the first link rotates clockwise. The end of the support assembly connected to the first link rotates counterclockwise under the drive of the first link. As the support assembly rotates with the adapter, it can also rotate counterclockwise itself, thereby increasing the rotation range of the support assembly. Thus, when adjusting the angle of the support assembly, the required stroke of the driving component is smaller, reducing the overall space required by the driving mechanism.

[0025] This application also provides a vehicle including the aforementioned seat assembly, which is mounted on the vehicle body. The seat assembly can be used for passenger seating.

[0026] Therefore, the above-mentioned technical features of this application have the following beneficial effects:

[0027] (1) During the installation of the seat assembly, since the leg support assembly is set on the mounting base plate and the seat assembly is set on the mounting base plate, there is no need to consider the assembly problem between the leg support assembly and the seat assembly, which greatly simplifies the structure of the seat assembly and makes the design and processing of the seat assembly more convenient.

[0028] (2) The leg support assembly is directly connected to the mounting base plate via the mounting bracket, and is not connected to the seat assembly. When the leg support assembly malfunctions and needs repair or replacement, the mounting bracket can be separated from the mounting base plate to remove the leg support assembly, making it easy to repair.

[0029] (3) After the passenger sits on the seat assembly, the angle of rotation of the support assembly around the mounting bracket can be adjusted to adjust the position of the support assembly, ensuring that the passenger's legs can be comfortably placed on the support assembly, which can relieve the passenger's leg fatigue during the ride.

Detailed Implementation

[0044] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0045] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0046] This application provides a vehicle, which includes a vehicle body and a seat assembly disposed inside the vehicle body. The seat assembly can be used to carry passengers. It is understood that the vehicle provided in this application may also include other components, such as an engine, a transmission mechanism, etc., to realize the basic functions of the vehicle.

[0047] The following is a further description of the seat assembly provided in the embodiments of this application, such as... Figure 1 As shown, Figure 1 This is one of the structural schematic diagrams of a vehicle seat assembly 100 provided in an embodiment of this application. The vehicle seat assembly 100 is used to mount on a mounting base 1 of a vehicle. The vehicle seat assembly 100 includes a seat component 2 and a leg support component 3. The seat component 2 is mounted on and connected to the mounting base 1. The leg support component 3 is mounted on the mounting base 1 and located on one side of the seat component 2. During the installation of the vehicle seat assembly 100, since the leg support component 3 is mounted on the mounting base 1 and the seat component 2 is mounted on the mounting base 1, there is no need to consider the assembly problem between the leg support component 3 and the seat component 2, which greatly simplifies the structure of the seat component 2 and makes the design and processing of the seat component 2 more convenient.

[0048] The leg support assembly 3 includes a mounting bracket 301 and a support assembly 302. The mounting bracket 301 is connected to the mounting base plate 1. During the installation of the leg support assembly 3, the leg support assembly 3 is directly connected to the mounting base plate 1 via the mounting bracket 301, and the leg support assembly 3 is not connected to the seat assembly 2. When the leg support assembly 3 malfunctions and needs repair or replacement, the leg support assembly 3 can be disassembled by separating the mounting bracket 301 from the mounting base plate 1, facilitating repair of the leg support assembly 3.

[0049] The support component 302 can rotate relative to the mounting bracket 301, moving closer to or further away from the mounting bracket 301. After a passenger sits on the seat component 2, the rotation angle of the support component 302 around the mounting bracket 301 can be adjusted to adjust the position of the support component 302, ensuring that the passenger's legs can be comfortably placed on the support component 302, which can alleviate leg fatigue during the journey.

[0050] To ensure the stability of the connection between the leg support assembly 3 and the mounting base plate 1, in some embodiments, such as... Figure 1 As shown, the mounting base plate 1 has a stepped surface 101. The stepped surface 101 includes a first mounting surface 1011 and a second mounting surface 1012 that are connected to each other and intersect. Thus, the first mounting surface 1011 and the second mounting surface 1012 can have a certain angle between them.

[0051] like Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of the mounting bracket 301 provided in an embodiment of this application. The mounting bracket 301 includes a mounting member 3011, which includes a first mounting plate 30111 and a second mounting plate 30112 connected to each other. One end of the first mounting plate 30111 is connected to the second mounting plate 30112, and an angle is formed between them. The first mounting plate 30111 and the first mounting surface 1011 ( Figure 1 The second mounting plate 30112 is attached to the first mounting surface 1011 and connected to it. Figure 1 It fits and is connected to the second mounting surface 1012.

[0052] Since the first mounting surface 1011 and the second mounting surface 1012 can have a certain angle, the first mounting plate 30111, which is attached to the first mounting surface 1011, and the second mounting plate 30112, which is attached to the second mounting surface 1012, can also form a certain angle. In this way, the first mounting plate 30111 and the second mounting plate 30112 can fix the mounting bracket 301 from different directions, thereby ensuring the stability of the connection between the mounting bracket 301 and the mounting base plate 1.

[0053] It is understood that the angle between the first mounting surface 1011 and the second mounting surface 1012 can be adjusted according to actual needs, for example, such as Figure 1 As shown, the first mounting surface 1011 and the second mounting surface 1012 are perpendicular to each other, forming a right-angled step. Correspondingly, the first mounting plate 30111 and the second mounting plate 30112 are also perpendicular to each other, respectively fitting against the first mounting surface 1011 and the second mounting surface 1012. When the mounting component 3011 shakes, the fitting of the first mounting plate 30111 with the first mounting surface 1011 can resist vertical shaking, and the fitting of the second mounting plate 30112 with the second mounting surface 1012 can resist shaking in the direction perpendicular to the first mounting plate 30111, thereby effectively improving the stability of the connection between the mounting component 3011 and the stepped surface 101.

[0054] To facilitate positioning the relative position of the leg support assembly 3 and the mounting base plate 1 during installation, in some embodiments, such as... Figure 2 As shown, the mounting component 3011 also includes a positioning post 30113. The positioning post 30113 is disposed on one of the first mounting plate 30111 and the second mounting plate 30112, and is located on the side of the first mounting plate 30111 and the second mounting plate 30112 that are close to each other. The positioning post 30113 passes through the mounting base plate 1 (…). Figure 1 )superior.

[0055] After installing the leg support assembly 3 on the mounting base plate 1 ( Figure 1 During the process of mounting, since the positioning post 30113 is located on the side where the first mounting plate 30111 and the second mounting plate 30112 are close to each other, the side where the first mounting plate 30111 and the second mounting plate 30112 are close to each other is adjacent to the mounting base plate 1. Figure 1 ) stepped surface 101 ( Figure 1 As the mounting bracket 301 approaches the mounting base plate 1, the two plates fit together. Figure 1The positioning post 30113 can be inserted into the mounting base plate 1. Figure 1 ), thereby connecting the mounting bracket 301 and the mounting base plate 1 ( Figure 1 The relative positions between the components are fixed to facilitate subsequent fixing of the leg support assembly 3 to the mounting base 1. Figure 1 )superior.

[0056] Since the positioning post 30113 is disposed on one of the first mounting plate 30111 and the second mounting plate 30112, as the first mounting plate 30111 and the second mounting plate 30112 approach the stepped surface, the positioning post 30113 is inserted into the mounting base plate 1 in the same direction. Figure 1 On the other hand, there will be no interference between them.

[0057] For example, such as Figure 2 As shown, the positioning post 30113 is a cylindrical post, and the positioning post 30113 is connected to the first mounting plate 30111. Figure 1 As shown, the mounting base plate 1 is provided with positioning holes 102. The position of the positioning holes 102 corresponds to the positioning pins 30113. When positioning the mounting bracket 301 onto the mounting base plate 1, firstly, the side of the second mounting plate 30112 closest to the first mounting plate 30111 is attached to the second mounting surface 1012. Then, the side of the first mounting plate 30111 closest to the second mounting plate 30112 is attached to the first mounting surface 1011. As the first mounting plate 30111 approaches the first mounting surface 1011, the positioning pins 30113 can be inserted into the positioning holes 102, thereby defining the position of the mounting bracket 301 and the mounting base plate 1.

[0058] It is understood that in some other embodiments, the positioning post 30113 can be connected to the second mounting plate 30112. When positioning the mounting bracket 301 onto the mounting base plate 1, the side of the first mounting plate 30111 closest to the second mounting plate 30112 is first attached to the first mounting surface 1011, and then the side of the second mounting plate 30112 closest to the first mounting plate 30111 is attached to the second mounting surface 1012. As the second mounting plate 30112 approaches the first mounting surface 1011, the positioning post 30113 can also be inserted into the positioning hole 102, thereby defining the position of the mounting bracket 301 and the mounting base plate 1.

[0059] In some embodiments, such as Figure 2As shown, there are two mounting members 3011. The mounting bracket 301 also includes a connector 3012. Along the extending direction of the connector 3012, the two mounting members 3011 are located at both ends of the connector 3012 and connected to it. Thus, the two mounting members 3011 are located at both ends of the mounting bracket 301, which is composed of the two mounting members 3011 and the connector 3012. The two mounting members 3011 can fix the mounting bracket 301 from both ends of the mounting bracket 301, ensuring that the mounting bracket 301 is fixed to the mounting base plate 1. Figure 1 The stability of the connection.

[0060] It should be noted that the number of mounting components 3011 can be adjusted according to actual needs. For example, there can be three mounting components 3011, located at both ends and the middle of the connector 3012 along its extension direction. In this way, the mounting components 3011 can fix the mounting bracket 301 from both ends and the middle, ensuring the stability of the mounting bracket 301.

[0061] In some embodiments, such as Figure 2 As shown, the mounting component 3011 also includes a fixing plate 3013. One side of the fixing plate 3013 is connected to the connector 3012. The first mounting plate 30111 and the second mounting plate 30112 are located on the side of the fixing plate 3013 away from the connector 3012 and are connected to the fixing plate 3013.

[0062] In practical use, the first mounting plate 30111 and the second mounting plate 30112 are connected together with the fixing plate 3013 to form a structure similar to a reinforcing rib, which can improve the strength of the first mounting plate 30111 and the second mounting plate 30112 and prevent deformation of the first mounting plate 30111 and the second mounting plate 30112.

[0063] During the installation or disassembly of the mounting bracket 301, since the first mounting plate 30111 and the second mounting plate 30112 are located on the side of the fixing plate 3013 away from the connector 3012, when the operator uses tools to disassemble and install the first mounting plate 30111 and the second mounting plate 30112, the tools will not interfere with the connector 3012, making it easier to disassemble and install the mounting bracket 301.

[0064] To maintain the stability of the mounting component 3011, in some embodiments, such as Figure 2As shown, the connector 3012 includes multiple connecting shafts 30121. One end of each connecting shaft 30121 is connected to one of the mounting members 3011, and the other end is connected to another mounting member 3011. The multiple connecting shafts 30121 can provide support at different positions of the mounting members 3011 located at both ends of the connector 3012, thereby ensuring that different positions of the mounting members 3011 can be supported, thus improving the stability of the mounting members 3011.

[0065] For example, such as Figure 2 As shown, there are two connecting shafts 30121, which are arranged parallel to each other at intervals along the first direction X. The two connecting shafts 30121 are connected to two fixing plates 3013 respectively, thereby forming stable support for both ends of the fixing plates 3013 and making the fixing plates 3013 less prone to deformation.

[0066] In some embodiments, such as Figure 2 As shown, the connecting shaft 30121 may include a horizontal section (not shown) and two connecting sections (not shown). The horizontal section extends along a first direction X, and the two connecting sections are located at both ends of the horizontal section. Along the first direction X, two fixing plates 3013 are spaced apart. Each fixing plate 3013 has a connecting through hole (not shown). The two connecting sections of the connecting shaft 30121 are respectively connected to the connecting through holes on the two fixing plates 3013. When the fixing plates 3013 on both sides tilt towards or away from each other, the connecting sections of the connecting shaft 30121 inserted into the connecting through holes on the fixing plates 3013 can provide support to the fixing plates 3013 on both sides, preventing the fixing plates 3013 from tilting and ensuring that the mounting bracket 301 does not deform.

[0067] In some embodiments, such as Figure 3 As shown, Figure 3 This is a schematic diagram of the leg support assembly 3 provided in an embodiment of this application. The leg support assembly 3 also includes a drive mechanism 303. The drive mechanism 303 is connected to the mounting bracket 301 and to the support assembly 302. The drive mechanism 303 is used to move the support assembly 302 away from or towards the mounting bracket 301. Passengers can adjust the position of the support assembly 302 by adjusting the drive mechanism 303, which can fix the support assembly 302 in a comfortable position, improving passenger comfort.

[0068] In some embodiments, such as Figure 4 As shown, Figure 4 This is one of the exploded views of the drive mechanism 303 provided in the embodiments of this application. The drive mechanism 303 includes a connecting rod 3031, a drive motor 3032, a drive component 3033, an adapter 3034, and a driving component 3035. The connecting rod 3031 and the mounting bracket 301 ( Figure 3The drive motor 3032 is rotatably connected to the connecting rod 3031. The drive component 3033 is connected to the output shaft 30321 of the drive motor 3032. The drive motor 3032 drives the drive component 3033 to slide along the extension direction of the output shaft 30321. The sliding direction of the drive component 3033 is perpendicular to the rotation axis direction of the drive motor 3032.

[0069] One end of the adapter 3034 is rotatably connected to the connecting rod 3031, and the rotation axis of the adapter 3034 is parallel to the rotation axis of the drive motor 3032. This ensures that the adapter 3034 and the drive motor 3032 will not interfere with each other during rotation, guaranteeing normal rotation. The other end of the adapter 3034 is connected to the support assembly 302 (…). Figure 3 )connect.

[0070] One end of the driving component 3035 is rotatably connected to the driving component 3033, and the rotation axis is parallel to the rotation axis of the drive motor 3032. The other end of the driving component 3035 is connected to the adapter 3034, and is used to drive the adapter 3034 to rotate around the rotation axis.

[0071] After the drive motor 3032 starts, it drives the drive component 3033 to move along the extension direction of the output shaft 30321. Simultaneously, the driving component 3035, which is rotatably connected to the drive component 3033, moves synchronously. Since one end of the driving component 3035 is connected to the adapter 3034, the adapter 3034 rotates around its rotation axis under the drive of the drive component 3035. This drives the support assembly 302 to move, thus enabling the support assembly 302 (… Figure 3 Position adjustment.

[0072] For example, such as Figure 5 As shown, Figure 5 This is one of the structural schematic diagrams of the drive mechanism 303 provided in the embodiments of this application. Connecting portions 30311 are formed at both ends of the connecting rod 3031. Through holes (not shown in the figure) are provided on the connecting portions 30311. The connecting portions 30311 are connected to the fixing plate 3013 through the through holes (not shown in the figure). Figure 2 ) connect, thereby connecting the connecting rod 3031 to the mounting bracket 301 ( Figure 2 ) are connected together.

[0073] like Figure 6As shown, a rotating part (not shown) is formed on the connecting rod 3031, and the drive motor 3032 is rotatably connected to the rotating part by bolts. The surface of the output shaft 30321 of the drive motor 3032 may be threaded, and a transmission through hole (not shown) is formed on the drive member 3033. The inner surface of the transmission through hole (not shown) has a thread that matches the thread on the surface of the output shaft 30321. The output shaft 30321 passes through the transmission through hole (not shown) and is connected to the drive member 3033 in a transmission manner. Furthermore, the rotation axis of the output shaft 30321 is perpendicular to the rotation axis of the drive motor 3032.

[0074] A transmission groove (not shown in the figure) is formed on the driving member 3035. The adapter 3034 includes two parallel first adapters 30341 and a second adapter 30342, with both ends of the second adapter 30342 connected to the two first adapters 30341 respectively. The second adapter 30342 is engaged in the transmission groove. Because the second adapter 30342 is engaged in the transmission groove, it can restrict the driving member 3035, making the rotation direction of the driving member 3035 consistent with that of the second adapter 30342, that is, the rotation direction of the driving member 3035 is consistent with the overall rotation direction of the adapter 3034. Since the drive member 3035 is rotatably connected to the drive member 3033 and the axis of rotation is consistent with the adapter 3034, the drive member 3035 can restrict the drive member 3033, preventing the drive member 3033 from rotating with the output shaft 30321, thereby ensuring that the output shaft 30321 can drive the drive member 3033 to move along the extension direction of the output shaft 30321.

[0075] When the driving component 3033 moves away from the drive motor 3032 along the output shaft 30321, the driving component 3035 moves away from the drive motor 3032 along with the driving component 3033. During this movement, the driving component 3035 rotates counterclockwise, and the second adapter 30342 rotates accordingly, thereby causing the first adapter 30341 to rotate counterclockwise around the rotation axis. As the first adapter 30341 rotates counterclockwise, the support assembly 302 ( Figure 3 It will lift upwards.

[0076] In some embodiments, such as Figure 4 As shown, the drive mechanism 303 also includes two sets of linkage assemblies 3036. Along the rotation axis of the adapter 3034, the two sets of linkage assemblies 3036 are located on both sides of the adapter 3034.

[0077] Linkage assembly 3036 includes a first link 30361, a second link 30362, and a third link 30363. The first link 30361 is rotatably connected to the adapter 3034, and one end is connected to the support assembly 302. Figure 3The second link 30362 is located on the side of the first link 30361 away from the drive motor 3032, with one end rotatably connected to the adapter 3034 and the other end connected to the support assembly 302. Figure 3 Rotary connection. One end of the third link 30363 is rotatably connected to the other end of the first link 30361, and the other end is rotatably connected to the connecting rod 3031.

[0078] Connecting rod 3031 is connected to support assembly 302 via first link 30361 and third link 30363. Figure 3 The first link 30361, the second link 30362, and the third link 30363 are all parallel to the rotation axis of the drive motor 3032.

[0079] As the support assembly 302 is lifted upwards, the adapter 3034 rotates counterclockwise. Since the first link 30361 is rotatably connected to the adapter 3034, the first link 30361 moves synchronously with the adapter 3034. Simultaneously, because one end of the third link 30363 is rotatably connected to the other end of the first link 30361, and the other end is rotatably connected to the connecting rod 3031, the movement of the first link 30361 is restricted by the third link 30363. At this time, the third link 30363 rotates counterclockwise, and the first link 30361 rotates clockwise. Support assembly 302 ( Figure 3 The end of the first link 30361 connected to the first link 30361 rotates counterclockwise under the drive of the first link 30361. Correspondingly, the second link 30362 rotates clockwise at this time, driving the support assembly 302 ( Figure 3 The end connected to the second link 30362 rotates counterclockwise. Support assembly 302 ( Figure 3 As the adapter 3034 rotates, it can also rotate counterclockwise, thereby improving the support assembly 302. Figure 3 The rotation range of the support component 302. Figure 3 When the angle is adjusted, the required stroke of the drive component 3033 is smaller, which can reduce the overall space required by the drive mechanism 303.

[0080] To facilitate passenger adjustment of the position of the support assembly 302, in some embodiments, such as Figure 1As shown, the seat assembly 100 also includes an adjustment button 4 and a leg rest wiring harness 5. The adjustment button 4 is located on the seat assembly 2. One end of the leg rest wiring harness 5 is connected to the adjustment button 4, and the other end is connected to the drive motor 3032 of the drive mechanism 303. The adjustment button 4 is electrically connected to the drive motor 3032 of the drive mechanism 303 through the leg rest wiring harness 5. When a passenger sits on the seat assembly 2, they can control the movement of the drive motor 3032 of the drive mechanism 303 with the adjustment button 4, thereby adjusting the position of the support assembly 302 through the drive mechanism 303.

[0081] In some embodiments, such as Figure 4 As shown, the support assembly 302 includes a leg support mounting plate 304 and a rotating frame 305. One end of the first connecting rod 30361 is connected to the rotating frame 305, and the other end of the second connecting rod 30362 is connected to the rotating frame 305. The leg support mounting plate 304 is connected to the rotating frame 305 and is located on the side of the rotating frame 305 away from the drive motor 3032.

[0082] In some embodiments, such as Figure 7 As shown, Figure 7 This is a schematic diagram of the structure of the support component 302 provided in the embodiment of this application. The support component 302 also includes a leg support bracket 3021, a leg support foam layer 3022, and a leg support cover 3023. The leg support bracket 3021 is connected to the leg support mounting plate 304.

[0083] The leg rest foam layer 3022 wraps around the side of the leg rest bracket 3021 away from the drive mechanism 303. The leg rest foam layer 3022 is made of a soft material, which improves the comfort of the leg rest bracket 3021. The leg rest cover 3023 wraps around the outside of the leg rest foam layer 3022, and comes into contact with the passenger's legs when the passenger places their legs on the support component 302. Dust from the passenger's clothing is blocked by the leg rest cover 3023, preventing it from soiling the inner leg rest foam layer 3022. When the support component 302 needs cleaning, simply remove the leg rest cover 3023 for washing.

[0084] To improve the stability of the leg support cover 3023, in some embodiments, such as Figure 7 As shown, a groove 30211 is formed on the side of the leg support bracket 3021 near the drive mechanism 303. The leg support bracket 3021 also includes multiple hooks 3024. The multiple hooks 3024 are disposed on the peripheral wall of the groove 30211, and the edge of the leg support cover 3023 is connected to the hooks 3024. The hooks 3024 can fix the position of the leg support cover 3023, so that the leg support cover 3023 will not fall off when the passenger's leg moves on the surface of the leg support cover 3023.

[0085] To facilitate the disassembly of the support assembly 302, in some embodiments, such as Figure 7 As shown, the leg support bracket 3021 also includes multiple snap fasteners 3025. The multiple snap fasteners 3025 are located within the groove 30211 and are connected to the bottom wall of the groove 30211. Figure 5 As shown, a snap-fit ​​slot 3041 is formed on the leg support mounting plate 304, and a snap-fit ​​3025 is snapped into the snap-fit ​​slot 3041.

[0086] According to the above, since the buckle 3025 is engaged in the buckle slot 3041, when it is necessary to remove the leg support bracket 3021, the leg support bracket 3021 can be separated from the leg support mounting plate 304 without the aid of tools, and the leg support bracket 3021 can be easily removed.

[0087] In some embodiments, such as Figure 8 As shown, Figure 8 This is a cross-sectional view of the seat assembly 2 provided in an embodiment of this application. The seat assembly 2 includes a seat base 201, and the seat base 201 and the mounting base 1 ( Figure 1 ) connection. The seat base 201 is close to the mounting base 1 ( Figure 1 A mounting cavity 2011 with an opening is formed on one side of the support assembly 302. The leg support assembly 3 is located inside the mounting cavity 2011. In this way, when the support assembly 302 is in the retracted state, the leg support assembly 3 can be retracted into the mounting cavity 2011, reducing the space occupied in the vehicle interior.

[0088] To ensure passenger comfort, such as Figure 8 As shown, the seat assembly 2 includes a seat panel 202 and a backrest 203. The seat panel 202 is located on the seat base 201 away from the mounting base 1. Figure 1 The backrest 203 is located on one side of the seat panel 202 away from the seat base 201 and is connected to the seat panel 202. The backrest 203 is located at the end of the seat panel 202 away from the mounting cavity 2011.

[0089] When passengers are riding in a vehicle, if Figure 9 As shown, Figure 9 This is a second schematic diagram of the vehicle seat assembly 100 provided in this application embodiment. The passenger sits on the seat panel 202, with the passenger's center of gravity located near the backrest 203. Due to the mounting cavity 2011 ( Figure 8 Located at the end furthest from the backrest 203, the structure below one end of the backrest 203 is not affected by the mounting cavity 2011. Figure 8 The opening of the seat back 203 will not reduce the thickness of the foam layer (not shown in the figure), thus ensuring passenger comfort.

[0090] To ensure the stability of the seat assembly 2, in some embodiments, such as Figure 1As shown, the seat assembly 2 also includes a retaining clip 204. The retaining clip 204 is located at the opening and connects to the seat base 201. The seat assembly 100 also includes a locking clip 8, connected to the leg rest assembly 3, located on the side of the leg rest assembly 3 near the seat plate 202. The retaining clip 204 is connected to the locking clip 8. After the retaining clip 204 and the locking clip 8 are connected together, one end of the seat base 201 can be connected to the leg rest assembly 3, improving the stability of the seat base 201 installation.

[0091] For example, such as Figure 5 As shown, a connecting sheet metal (not shown in the figure) is provided on the connecting rod 3031, and a mounting groove (not shown in the figure) is formed on the connecting sheet metal, and a locking buckle 8 ( Figure 1 It connects to the mounting slot. 204 fixing clip. Figure 1 ) and locking buckle 8 ( Figure 1 After connecting them together, the seat base 201 can be connected. Figure 8 It is fixed together with the connecting rod 3031, which can improve the stability of the seat base 201.

[0092] In some embodiments, such as Figure 10 As shown, Figure 10 The third schematic diagram of the drive mechanism 303 provided in this application embodiment shows that the drive mechanism 303 may further include a first shield 306 and a second shield 307. Along the rotation axis of the adapter 3034, the first shield 306 is located on both sides of the connecting rod assembly 3036 and connected to the adapter 3034. In this way, the first shield 306 can protect the drive mechanism 303 from both sides of the adapter 3034, preventing debris from entering the movement stroke of the drive mechanism 303 and affecting its normal operation.

[0093] Along the rotation axis of the rotating frame 305, the second shield 307 is located on both sides of the connecting rod assembly 3036 and connected to the rotating frame 305. The second shield 307 can protect the drive mechanism 303 from the rotating frame 305, preventing foreign objects from entering the movement stroke of the drive mechanism 303 from the position of the rotating frame 305 and affecting the normal operation of the drive mechanism 303.

[0094] The second cover plate 307 is located on the side of the first cover plate 306 away from the connecting rod assembly 3036. In this way, no collision will occur between the first cover plate 306 and the second cover plate 307 during the rotation of the adapter 3034 and the rotating frame 305.

[0095] For example, such as Figure 11 As shown, Figure 11The second exploded view of the drive mechanism 303 provided in this application embodiment shows that the first shield 306 has two parallel shielding surfaces 3061, 3062, and 3063. Along the rotation axis of the adapter 3034, the two shielding surfaces 3061 are located on both sides of the connecting rod assembly 3036 and connected to the adapter 3034. The two shielding surfaces 3061 can prevent debris from affecting the operation of the drive mechanism 303 from both sides.

[0096] The second shielding surface 3062 is located on the side of the first shielding surface 3061 away from the drive motor 3032, and is connected to both first shielding surfaces 3061. The second shielding surface 3062 can prevent debris from affecting the operation of the drive mechanism 303 from below. The third shielding surface 3063 is located on the side of the first shielding surface 3061 closer to the rotating frame 305. The third shielding surface 3063 can prevent debris from affecting the operation of the drive mechanism 303 from the direction of the rotating frame 305.

[0097] Continue to refer to Figure 11 The second shield 307 has two parallel fourth shielding surfaces 3071 and a fifth shielding surface 3072. Along the rotation axis of the rotating frame 305, the two fourth shielding surfaces 3071 are located on both sides of the connecting rod assembly 3036 and connected to the rotating frame 305. The fourth shielding surfaces 3071 can block debris from both sides of the rotating frame 305, preventing debris from entering the movement range of the rotating frame 305.

[0098] The fourth shielding surfaces 3071 on both sides are located on the side of the first shielding surfaces 3061 that are away from the connecting rod assembly 3036. In this way, the fourth shielding surface 3071 will not diverge and interfere with the first shielding surface 3061 and the third shielding surface 3063 during the movement with the rotating frame 305.

[0099] The fifth shielding surface 3072 is located on the side of the fourth shielding surface 3071 away from the drive motor 3032. It can shield debris from the side of the fourth shielding surface 3071 away from the drive motor 3032, preventing debris from entering the movement range of the rotating frame 305.

[0100] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
