[0025] The following is for reference. Figures 1-7 The leg support assembly 100 according to an embodiment of the present invention can be raised and extended to meet different user needs, improve riding comfort, and ensure the reliability of the installation of the leg support plate 2, thereby ensuring the reliability of the leg support assembly 100 in supporting the user's legs.

[0026] like Figures 1-7 As shown, a leg support assembly 100 according to an embodiment of the present invention includes: a leg support lifting structure 7, a leg support mounting structure 1, a leg support plate 2, and a first drive assembly 6.

[0027] One end of the leg support lifting structure 7 is connected to the seat cushion frame 101, and the other end of the leg support lifting structure 7 is connected to the leg support mounting structure 1 to selectively lift the leg support mounting structure 1. The leg support mounting structure 1 forms a receiving space 131, and a guide member 14 is provided in the receiving space 131. The leg support plate 2 is slidably installed in the receiving space 131 and is retractable relative to the leg support mounting structure 1. The leg support plate 2 is provided with a guide engagement member 21 that slides with the guide member 14. The first drive assembly 6 is installed on the leg support mounting structure 1, and the first drive assembly 6 is used to drive the leg support plate 2 to retract relative to the leg support mounting structure 1.

[0028] The seat 1000 includes a seat cushion frame 101 and a backrest frame 102. The seat cushion frame 101 is located below the seat 1000, and the backrest frame 102 is rotatably connected to the seat cushion frame 101. The seat cushion frame 101 is located below the backrest frame 102, allowing occupants to sit on the seat cushion frame 101 and lean against the backrest frame 102. The backrest frame 102 can be angled according to the occupant's usage habits. A drive rocker arm, transmission link, and drive assembly can be installed at the seat cushion frame 101 to adjust the tilt angle of the seat 1000. The leg rest assembly 100 is installed at the front end of the seat cushion frame 101 and can be raised or lowered in conjunction with the backrest frame 102. This allows occupants to adjust the overall shape of the seat 1000 according to their own conditions and habits to achieve a comfortable seating posture, meet different occupant needs, and improve comfort and seating experience.

[0029] Specifically, the leg support assembly 100 is provided with a leg support lifting structure 7 and a leg support mounting structure 1. The leg support lifting structure 7 is used to adjust the overall lifting height of the leg support assembly 100. One end of the leg support lifting structure 7 can be movably connected to the front side of the seat cushion frame 101, and the other end of the leg support lifting structure 7, that is, the end away from the seat cushion frame 101, can be connected to the leg support mounting structure 1. This allows the leg support lifting structure 7 to drive the leg support mounting structure 1 to lift or lower when it moves, so as to meet different usage needs. The leg support lifting structure 7 can be set as a linkage drive or a direct motor drive, etc., with flexible setting methods.

[0030] Furthermore, the leg support assembly 100 is also equipped with a leg support plate 2. The leg support plate 2 has a flat plate structure and can be installed on the leg support mounting structure 1. The user can place their legs on the upper surface of the leg support plate 2, so that the leg support plate 2 can support the user's legs to reduce leg pressure. In actual use, a soft padding structure can be installed on the surface of the leg support plate 2 to improve the user's riding comfort. The leg support mounting structure 1 also forms an accommodating space 131 that opens towards the user's legs. The leg support plate 2 can be accommodated in the accommodating space 131, so that the accommodating space 131 can limit the leg support plate 2, so that the leg support plate 2 can only slide relative to the leg support mounting structure 1 in the leg length direction, ensuring operational stability and improving the reliability of the leg support plate 2 in supporting the legs.

[0031] Furthermore, a guide 14 is provided within the accommodating space 131. The guide 14 can be configured as a guide groove or a guide rail, etc. The guide 14 is configured to extend along the length direction of the leg. The leg support plate 2 is provided with a guide mating part 21. The guide mating part 21 can be configured as a guide rail or a guide block, etc. When the leg support plate 2 is installed in the accommodating space 131, the guide 14 and the guide mating part 21 can engage in a guiding fit, thereby allowing the leg support plate 2 to slide relative to the leg support mounting structure 1 to adjust the overall length of the leg support plate 2 and the leg support mounting structure 1, meet the user's different leg length usage needs, and also ensure the accuracy of the running trajectory of the leg support plate 2 to ensure reliable use.

[0032] In addition, the leg support assembly 100 is also provided with a first drive component 6. The first drive component 6 can be installed on the leg support mounting structure 1 and is located on the side of the leg support plate 2 away from the user's legs to avoid affecting the user's experience. The first drive component 6 can be poweredly connected to the leg support plate 2, so that when the user uses the leg support assembly 100 and adjusts the extension length of the leg support assembly 100, the first drive component 6 can drive the leg support plate 2 to slide relative to the leg support mounting structure 1, thereby improving automation, improving ease of use, and ensuring the user's experience.

[0033] According to an embodiment of the present invention, the leg support assembly 100 is provided with a leg support lifting structure 7 and a leg support mounting structure 1, and the leg support plate 2 is telescopic relative to the leg support mounting structure 1. This allows the leg support assembly 100 to be adjusted for lifting and telescopic movement, meeting different user needs and improving riding comfort. The leg support mounting structure 1 forms a receiving space 131, and the leg support plate 2 slides with the guide member 14 in the receiving space 131 through the guide fitting member 21. The receiving space 131 can limit the leg support plate 2, ensuring the reliability of the leg support plate 2 installation while allowing the leg support plate 2 to telescopically move relative to the leg support mounting structure 1. This ensures the reliability of the leg support assembly 100 in supporting the user's legs, resulting in better performance and a wider range of applications.

[0034] In some embodiments, the leg support mounting structure 1 includes a connecting mounting bracket 11 and two guide mounting brackets 12. The two guide mounting brackets 12 are spaced apart along a second direction and are respectively connected to the leg support lifting structure 7. The connecting mounting bracket 11 is connected between the two guide mounting brackets 12. The guide member 14 extends along a first direction and is disposed on the guide mounting bracket 12, allowing the leg support plate 2 to slide along the first direction. The first drive assembly 6 is connected to the connecting mounting bracket 11. The first direction intersects with the second direction.

[0035] Specifically, the leg support mounting structure 1 is used to mount the leg support plate 2 and can be connected to the leg support lifting structure 7, and as... Figures 2-3As shown, the leg support mounting structure 1 is provided with a connecting mounting bracket 11 and a guide mounting bracket 12. The guide mounting bracket 12 is provided in two and spaced apart along the second direction. The connecting mounting bracket 11 can be constructed to extend along the second direction and be connected to the two guide mounting brackets 12 at both ends by welding or other means. The leg support lifting structure 7 can be connected to the guide mounting bracket 12 by bolts or other connecting parts, so that the leg support lifting structure 7 can lift the entire leg support mounting structure 1 through the guide mounting bracket 12. The first drive component 6 can be installed on the connecting mounting bracket 11, and the guide component 14 can be installed on the guide mounting bracket 12, thereby avoiding interference between the first drive component 6 and the guide component 14 and ensuring the operational stability of each structure.

[0036] Furthermore, the guide member 14 is disposed on the guide mounting bracket 12 and is configured to extend along the first direction, so that the guide member 14 and the guide mating member 21 can slide relative to each other along the first direction, thereby allowing the leg support plate 2 to extend or retract relative to the leg support mounting structure 1 along the first direction. The first direction and the second direction intersect. In this embodiment, the first direction and the second direction are arranged perpendicularly, and the first direction can be set as the length direction of the leg, and the second direction can be set as the width direction of the leg. This allows each guide mounting bracket 12 to support a single leg, distributing the weight of the leg to extend the service life of the leg support mounting structure 1 and reduce the overall weight of the leg support mounting structure 1, thereby improving lightweight design and extending the vehicle's range.

[0037] In some embodiments, the guide mounting bracket 12 includes a first sub-bracket 121 and a second sub-bracket 127. The first sub-bracket 121 is connected to the outside of the second sub-bracket 127, and the first sub-bracket 121 is configured as a part of the side wall of the receiving space 131. The second sub-bracket 127 is configured as a part of the bottom wall of the receiving space 131. The two ends of the connecting mounting bracket 11 are respectively connected to the two second sub-brackets 127, and the guide member 14 is disposed on the second sub-bracket 127.

[0038] Specifically, the guide mounting bracket 12 is configured as two, and as follows: Figures 2-3 As shown, each guide mounting bracket 12 is provided with a first sub-bracket 121 and a second sub-bracket 127. The first sub-bracket 121 is bent and connected to the side of the second sub-bracket 127 away from the other guide mounting bracket 12, that is, the outer side of the second sub-bracket 127. The accommodating space 131 is formed between the two guide mounting brackets 12, so that the first sub-bracket 121 can be constructed as part of the side wall of the accommodating space 131, and the second sub-bracket 127 can be constructed as part of the bottom wall of the accommodating space 131. This allows the leg support plate 2 to be supported above the second sub-bracket 127, and the first sub-bracket 121 can limit the leg support plate 2 in the second direction to ensure the reliability of the installation of the leg support plate 2.

[0039] Furthermore, the connecting mounting bracket 11 is located between the two guide mounting brackets 12, and both ends of the connecting mounting bracket 11 are connected to the two second sub-brackets 127 respectively, so that the connecting mounting bracket 11 can also be constructed as part of the bottom wall of the accommodating space 131. The second sub-brackets 127 extend along the first direction, and the connecting mounting bracket 11 extends along the second direction, so that the second sub-brackets 127 and the connecting mounting bracket 11 can support multiple points of the leg support plate 2, ensuring the reliability of the installation of the leg support plate 2. The guide member 14 is installed on the second sub-bracket 127, and each second sub-bracket 127 can be provided with one guide member 14, that is, the two second sub-brackets 127 can be provided with two guide members 14 distributed separately along the second direction, so that the two points of the leg support plate 2 can slide with the leg support mounting structure 1, ensuring the reliability of installation and relative sliding.

[0040] In actual setup, it can also be like this: Figure 4 As shown, a third sub-support 128 is provided on the guide mounting bracket 12. The third sub-support 128 is connected to the second sub-support 127 on the side away from the first sub-support 121 and protrudes towards the side away from the leg support plate 2. That is, both ends of the connecting mounting bracket 11 are connected to the two third sub-supports 128 respectively, and the leg support lifting structure 7 is also connected to the third sub-support 128. The guide member 14 is provided on the second sub-support 127, and the first drive assembly 6 is provided on the connecting mounting bracket 11. This allows the connection point between the leg support lifting structure 7 and the guide mounting bracket 12 to be away from the first drive assembly 6 and the guide member 14, so as to ensure the operational stability between the various structures.

[0041] In some embodiments, the first sub-support 121 is formed with a first limiting portion 126, and the leg support 2 is adapted to limit and press against the first limiting portion 126 when retracted to the maximum position.

[0042] Specifically, such as Figure 2 As shown, the first sub-support 121 and the second sub-support 127 are bent and connected and protrude towards the user's leg. The first sub-support 121 has a first limiting part 126, which can be constructed as a limiting protrusion or a limiting block. The first driving component 6 can drive the leg support plate 2 to slide relative to the leg support mounting structure 1 to expand or retract. When the leg support plate 2 is retracted to the maximum position relative to the leg support mounting structure 1, that is, when the length of the leg support plate 2 and the leg support mounting structure 1 along the first direction is the shortest, the leg support plate 2 can press against the first limiting part 126 to ensure the stability of the leg support plate 2 during operation.

[0043] In other embodiments, the guide member 14 is formed with a second limiting portion 141, and the guide mating member 21 is formed with a first limiting mating portion 211 and a second limiting mating portion 212. The first limiting mating portion 211 is adapted to limit and press against the second limiting portion 141 when it is contracted to the maximum position, and the second limiting mating portion 212 is adapted to limit and press against the second limiting portion 141 when it is extended to the maximum position.

[0044] Specifically, such as Figures 1-4 As shown, the leg support mounting structure 1 is provided with a guide member 14 and can be constructed as a guide rail. The leg support plate 2 is provided with a guide mating member 21 and can also be constructed as a guide rail. The guide member 14 is provided with a second limiting part 141, which can be constructed as a limiting plate or a limiting block, etc., and the second limiting part 141 is located at one end of the guide member 14. The guide mating member 21 is provided with a first limiting mating part 211 and a second limiting mating part 212. Both the first limiting mating part 211 and the second limiting mating part 212 can be constructed as a limiting plate or a limiting block, etc., and the first limiting mating part 211 and the second limiting mating part 212 are respectively located at both ends of the guide mating member 21.

[0045] Furthermore, the first limiting engagement portion 211 is adapted to limit and press against the second limiting portion 141 when retracted to the maximum position, and the second limiting engagement portion 212 is adapted to limit and press against the second limiting portion 141 when extended to the maximum position. The first driving assembly 6 can drive the leg support plate 2 to slide relative to the leg support mounting structure 1 to extend or retract. When the leg support plate 2 is retracted to the maximum position relative to the leg support mounting structure 1, that is, when the length of the leg support plate 2 and the leg support mounting structure 1 along the first direction is the shortest, the first limiting engagement portion 211 can press against the second limiting portion 141. When the leg support plate 2 is extended to the maximum position relative to the leg support mounting structure 1, that is, when the length of the leg support plate 2 and the leg support mounting structure 1 along the first direction is the longest, the second limiting engagement portion 212 can press against the second limiting portion 141.

[0046] Thus, when the leg support plate 2 is extended or retracted to its maximum position relative to the leg support mounting structure 1, the guide member 14 can limit the guide mating member 21, ensuring the reliability of the leg support plate 2 in operation.

[0047] In some embodiments, a first reinforcing member 3 and a second reinforcing member 4 are connected between two second sub-supports 127 and spaced apart. The two second sub-supports 127 are provided with inner connecting surfaces 129 facing each other, and the two ends of the first reinforcing member 3 are respectively connected to the two inner connecting surfaces 129. The two second sub-supports 127 are provided with outer connecting surfaces 130 facing away from each other, and the two ends of the second reinforcing member 4 are respectively connected to the two outer connecting surfaces 130.

[0048] Specifically, there are two second sub-supports 127, which are spaced apart along the second direction. Each second sub-support 127 has an inner connecting surface 129 facing each other and an outer connecting surface 130 facing away from each other. A first reinforcing member 3 and a second reinforcing member 4 are also provided between the second sub-supports 127. Both the first reinforcing member 3 and the second reinforcing member 4 can be constructed as reinforcing plates or reinforcing columns, etc. Both the first reinforcing member 3 and the second reinforcing member 4 have a support portion and two connecting portions. The two connecting portions are bent and connected to the ends of the connecting portions. The two connecting portions of the first reinforcing member 3 are respectively connected to the two inner connecting surfaces 129, so that the support portion of the first reinforcing member 3 can be supported between the two inner connecting surfaces 129. The two connecting portions of the second reinforcing member 4 are respectively connected to the two outer connecting surfaces 130, so that the support portion of the second reinforcing member 4 can be connected between the two inner connecting surfaces 129.

[0049] When the leg support mounting structure 1 is in use, the user's legs will exert a force on the leg support mounting structure 1, which will cause the two second sub-supports 127 to have a relative displacement tendency in the second direction. The first reinforcing member 3 can support the two second sub-supports 127 when they tend to move closer to each other, and the second reinforcing member 4 can provide a pulling force to bring the two second sub-supports 127 closer to each other when they tend to move away from each other, so as to ensure the reliability of the two second sub-supports 127 and thus ensure the overall stability of the leg support mounting structure 1.

[0050] In actual installation, if a third sub-support 128 is provided on the side of the second sub-support 127 away from the first sub-support 121, the inner connecting surface 129 is formed on the side of the two third sub-supports 128 facing each other, and the two ends of the first reinforcing member 3 are respectively connected to the two inner connecting surfaces 129 of the third sub-support 128, so the installation method is flexible.

[0051] In some embodiments, the first sub-support 121 includes an inner side plate 122, a top plate 123, and an outer side plate 124 connected in sequence. The inner side plate 122 and the outer side plate 124 are distributed opposite to each other and together with the top plate 123 define a support groove 125 open on one side. A third reinforcing member 5 is connected between the first sub-support 121 and the second sub-support 127. At least a portion of the third reinforcing member 5 is located in the support groove 125 and connected to the outer side plate 124.

[0052] Specifically, such as Figures 1-3As shown, the first sub-support 121 is connected to one side of the second sub-support 127, and the first sub-support 121 is provided with an inner side plate 122, a top plate 123, and an outer side plate 124.

The middle part of the second link 712 and the middle part of the third link 713 are rotatably connected. One end of the connecting rod 74 is connected to the third link 713 and is located between the second link 712 and the first mounting bracket 72. Thus, when the connecting rod 74 rotates, it can drive the third link 713 to rotate, thereby driving the first link 711, the second link 712 and the fourth link 714 to move together to complete the lifting and lowering of the leg support assembly 100. The structure is simple, the installation cost is low, and the reliability of use can be guaranteed.
