[0024] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0025] This embodiment is described by taking the actual application of a simple calf support bracket to a leg support assembly as an example.

[0026] like Figures 1 to 3 As shown, a simple calf support bracket includes a main beam 1, and side mounting plates 2 are symmetrically fixed at both ends of the main beam 1 in the length direction. The side mounting plates 2 are used for slidingly connecting the extension plates 8 of the leg support. A support shaft 3 is installed at the rear end of the side mounting plate 2. The support shaft 3 is used to flip the calf support bracket and install it on the base 14 at the front end of the seat bottom. In this embodiment, the base 14 is mainly used to support the entire calf support bracket. A support beam 4 extending backward is fixedly set on the rear side of the middle part of the main beam 1. A connecting part 5 is provided at the rear end of the support beam 4. The connecting part 5 is used to connect the synchronization component of the extension plate 8. The synchronization component can make the extension plate 8 extend synchronously when the leg support bracket rotates relative to the base 14. A hinge seat 6 is provided on the lower side of the middle part of the main beam 1. The hinge seat 6 is used to connect the flip drive mechanism 9 of the leg support. The flip drive mechanism 9 can make the leg support bracket flip.

[0027] The side mounting plate 2 provided on the main beam 1 facilitates the installation of the extension plate 8. The design of the connecting portion 5 further facilitates the installation of the synchronization component, thereby allowing the extension plate 8 to extend synchronously with the rotation of the leg rest. The support shaft 3 and the hinge seat 6 allow the leg rest bracket to be rotatably mounted on the front end of the seat. Based on this, the simplified calf leg rest bracket not only meets the requirements for the installation of all functional components of the leg rest, but also has the technical advantages of simple structure and easy processing and manufacturing, which can optimize the compactness of the leg rest structure and reduce the production cost of the leg rest.

[0028] Specifically, such as Figure 4As shown, the flip drive mechanism 9 includes a motor 9a, a screw 9b, and a drive block 9c. The motor 9a is hinged to the hinge base 6, the screw 9b is fixedly mounted to the output end of the motor 9a, and the drive block 9c is threadedly mounted on the screw 9b. The drive block 9c is also hinged below the end of the base 14 away from the main beam 1. With this design, when the motor 9a is running, the main beam 1 can flip relative to the base 14 under the transmission action of the screw 9b and the drive block 9c.

[0029] like Figure 1 As shown, a hinge hole 2e is formed at the rear end of the side mounting plate 2. The support shaft 3 is rotatably mounted in the hinge hole 2e on the inner side of the side mounting plate 2. The end of the support shaft 3 away from the side mounting plate 2 is fixed to the side of the base 14 by screws. This design allows the main beam 1 to rotate stably relative to the base 14.

[0030] like Figure 1 and Figure 4 As shown, in this embodiment, the main hinge seat 6 is formed with two downwardly extending hanging ears 6a, and the motor 9a is rotatably installed between the two hanging ears 6a. Such a design can make the motor 9a stably installed, and can also stably drive the main beam 1 to rotate relative to the base 14.

[0031] In this embodiment, both the main beam 1 and the supporting beam 4 are hollow rectangular tubes, and the supporting beam 4 is welded and fixed to the center of the rear side of the main beam 1. This design ensures a stable structure between the main beam 1 and the supporting beam 4. In addition, the top of the main beam 1 is formed with an array of first weight-reducing holes 1a. This design can reduce the overall weight of the leg support bracket, thereby reducing production costs.

[0032] Furthermore, the side mounting plate 2 is formed with a snap-in hole 2d having the same cross-section as the main beam 1. The end of the main beam 1 is inserted into the snap-in hole 2d, and the end of the main beam 1 protrudes outward beyond the outer surface of the side mounting plate 2. This design allows for a more stable installation of the side mounting plate 2. In this embodiment, to further ensure stable installation between the main beam 1 and the side mounting plate 2, the contact surfaces between the two are additionally secured by welding.

[0033] like Figure 1 As shown, the front end of the side mounting plate 2 has an extension portion 2a, and the upper end of the outer side of the side mounting plate 2 and the side of the extension portion 2a are formed with positioning holes 2b. The positioning holes 2b are used to fix the mounting slide rail 7, and the extension plate 8 is slidably mounted on the slide rail 7. In this embodiment, the side mounting plate 2 is also formed with second reduction holes 2c, and the second reduction holes 2c and the positioning holes 2b are alternately arranged in sequence. The second reduction holes 2c reduce the overall weight of the side mounting plate 2, and the alternating arrangement of the second reduction holes 2c and the positioning holes 2b makes the structure of the side mounting plate 2 more stable.

[0034] like Figure 1 As shown, the connecting portion 5 is a cylindrical structure and is fixedly mounted on the top of the rear end of the support beam 4. A mounting hole 5a is formed on the top of the connecting portion 5, and the synchronization component is associated with the extension plate 8 through the mounting hole 5a.

[0035] Specifically, the synchronization assembly includes a driving crossbar 10 and a connecting rod assembly 11, such as Figure 2 、 Figure 3 and Figure 5 As shown, the driving crossbar 10 and the extension plate 8 are arranged parallel to each other and are rotatably mounted on the front end of the base 6 via a linkage plate 12. The connecting rod assembly 11 includes a first connecting rod 11a, a second connecting rod 11b, and a third connecting rod 11c, which are hinged in sequence. The end of the first connecting rod 11a away from the second connecting rod 11b is hinged to the mounting hole 5a, the middle of the second connecting rod 11b is hinged to the middle of the driving crossbar 10, and the end of the third connecting rod 11c away from the second connecting rod 11b is hinged to the middle of the extension plate 8. With this design, when the main beam 1 rotates forward relative to the base 14 and unfolds, the connecting portion 5 rotates backward relative to the driving crossbar 10. At this time, the distance between the connecting portion 5 and the driving crossbar 10 increases, causing the connecting rod assembly 11 to slowly unfold, thereby causing the extension plate 8 to slide forward and unfold. When the main beam 1 is rotated and folded backward relative to the base 14 , the distance between the connecting portion 5 and the driving cross bar 10 becomes closer and closer, so the connecting rod assembly 11 can be slowly folded, thereby causing the extension plate 8 to slide and fold backward.

[0036] In this embodiment, a fourth link 11d is connected between the first link 11a and the third link 11c. The two ends of the fourth link 11d are hinged to the first link 11a and the third link 11c respectively, and the second link 11b and the fourth link 11d are arranged parallel to each other. With this design, the four-bar linkage can make the link assembly 11 more stable when unfolded and folded.

[0037] In this embodiment, when the main beam 1 is in the folded state, the linkage piece 12 can be rotated and folded inside the base 6 to ensure that the overall thickness of the leg support is low when it is folded.

[0038] like Figure 2 and Figure 3 As shown, a second extension plate 13 is also installed in a sliding manner at the front end of the extension plate 8. The second extension plate 13 can achieve secondary extension of the leg rest, further meeting the leg rest needs of passengers of different heights.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention. Such changes fall within the scope of protection of the present invention.
