All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0039] This application provides a submersible seat frame and a seat with the seat frame to solve the technical problems existing in the prior art: the technical solution of driving the seat basin by a push rod motor assembly and an anti-submersion crossbeam welding assembly has defects such as complex overall structure, easy interference between components, and difficulty in seat design.

[0040] In a first aspect, embodiments of this application provide a retractable seat frame, referring to... Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a submersible seat frame provided in an embodiment of this application. Figure 2 This is a partial structural diagram of the base in an embodiment of this application.

[0041] This application provides a sinkable seat frame including a base 100 and a seat cushion frame 200.

A slide rail 111 is inclinedly provided on the side plate 110. The extension direction of the slide rail 111 is consistent with the extension direction of the side plate 110. The height of the side of the slide rail 111 near the rear cross tube 130 is greater than the height of the side of the slide rail 111 near the front cross tube 120. The seat frame 200 is provided with a crank 240 and a sliding member 250. One end of the crank 240 is hinged to the front side of the seat frame 200, and the other end of the crank 240 is hinged to the front side of the side plate 110. The sliding member 250 is located on the outside of the seat frame 200 away from the crank 240 and is slidably connected to the slide rail 111. A power member 140 for driving the seat frame 200 to slide is provided on the front cross tube 120. The output end of the power member 140 is hinged to the front side of the seat frame 200.

[0043] Using the above technical solution, during descent, the power component 140 is activated, driving the seat frame 200, causing the sliding member 250 to slide from the higher end to the lower end of the slide rail 111. Simultaneously, the crank 240 swings clockwise forward, thereby causing the seat frame 200 to move forward and downward. The overall structure is simple and compact, and the power component 140 is mounted on the front cross tube 120 of the base 100. The output end of the power component 140 is hinged to the front side of the seat frame 200, effectively reducing potential interference between the power component 140 and other components during descent, which is beneficial for seat design.

[0044] Furthermore, the base 100 in this embodiment also includes a base rod 170, a front connecting ear 180, a rear connecting ear 190, a front rocker arm 150, and a rear rocker arm 160. Specifically, two base rods 170 can be provided, with the two base rods 170 arranged opposite each other. Two front connecting ears 180 and two rear connecting ears 190 are each provided, with the two front connecting ears 180 respectively located at one end of the two base rods 170, and the two rear connecting ears 190 located at the other end of the two base rods 170. Two front rocker arms 150 and two rear rocker arms 160 are each provided, with the two front rocker arms 150 corresponding to the two front connecting ears 180, and the two rear rocker arms 160 corresponding to the two rear connecting ears 190. A side plate 110 corresponds to a front connecting lug 180, a front rocker arm 150, a rear connecting lug 190, and a rear rocker arm 160 located on one side. One end of the front rocker arm 150 is hinged to the end of the side plate 110 near the front cross tube 120, and the other end of the front rocker arm 150 is hinged to the corresponding front connecting lug 180. One end of the rear rocker arm 160 is hinged to the end of the side plate 110 near the rear cross tube 130, and the other end of the rear rocker arm 160 is hinged to the corresponding rear connecting lug 190.

[0045] Furthermore, refer to Figure 3 , Figure 3 This is a schematic diagram of the seat frame structure in an embodiment of this application. The seat frame 200 in this embodiment includes two opposing side beams 210 and a front crossbar 220 and a rear crossbar 230 spaced apart on the side beams 210. The extending direction of the side beams 210 is consistent with the extending direction of the side plate 110, the extending direction of the front crossbar 220 is consistent with the extending direction of the front cross tube 120, and the extending direction of the rear crossbar 230 is consistent with the extending direction of the rear cross tube 130. Two cranks 240 are included, one crank 240 corresponding to one side beam 210. The two cranks 240 are respectively located on the inner side of the corresponding side beam 210 near the front crossbar 220. One crank 240 corresponds to one side plate 110. The front end of the side plate 110 is provided with a connecting part 112, and the end of the crank 240 away from the corresponding side beam 210 is hinged to the connecting part 112 on the corresponding side plate 110. In some embodiments, the seat frame 200 further includes a seat suspension 270, which is disposed within a rectangular frame formed by the side beam 210, the front crossbar 220, and the rear crossbar 230.

[0046] Reference Figure 4 and Figure 5 , Figure 4 This is a side view of a retractable seat frame provided in an embodiment of this application. Figure 5 The side plate, slide rail, side beam, and sliding joint in the embodiments of this application are along Figure 4 A sectional view cut by AA.

[0047] The slide rail 111 can be located on the two inner sides of the two side plates 110 that are close to each other. Two sliding members 250 can be correspondingly provided. The two sliding members 250 can be rotatably located on the two sides of the two side beams 210 that are far apart from each other and are located near the rear crossbar 230. The axis of rotation of the sliding member 250 is perpendicular to the extension direction of the slide rail 111. Specifically, the sliding member 250 can be a stepped bolt 251, and the cross section of the slide rail 111 can be set as a convex shape that matches the sliding member 250. In this way, the sliding stability of the seat frame 200 is ensured, and the sliding member 250 can also be effectively prevented from coming out of the slide rail 111, thereby improving the overall structural reliability.

[0048] Reference Figure 2 and Figure 6 , Figure 6 This is an exploded view of the front cross tube, motor bracket, and telescopic motor in an embodiment of this application. The power component 140 in this embodiment can be a linear motor such as a telescopic motor 141. The telescopic motor 141 is rotatably mounted on the front cross tube 120, and its output end is hinged to the front side of the seat frame 200. Specifically, a motor bracket 121 adapted to the telescopic motor 141 can be provided on the front cross tube 120, and the telescopic motor 141 is rotatably mounted on the motor bracket 121, thus rotatably mounting the telescopic motor 141 on the front cross tube 120. Furthermore, to ensure the compactness of the overall structure and the efficiency of power transmission, a push plate 260 can be provided on the front side of the seat frame 200. Specifically, the push plate 260 is rotatably mounted on the front cross bar 220, and the output end of the telescopic motor 141 is hinged to the end of the push plate 260 away from the front cross bar 220.

[0049] Reference Figure 1 and Figure 7 , Figure 7 This is a schematic diagram of a retractable seat frame in a retracted or folded state, as provided in an embodiment of this application. In some embodiments, the seat frame further includes a backrest frame 300. Specifically, the backrest frame 300 includes two connecting plates 310 and a backrest 320. Each connecting plate 310 corresponds to a side plate 110, and the two connecting plates 310 are respectively fixed to the side of the corresponding side plate 110 near the rear cross tube 130. The backrest 320 is rotatably disposed on both sides of the two connecting plates 310 that are close to each other. Further, the backrest frame 300 also includes a rotating shaft 330, which is rotatably disposed on both sides of the two connecting plates 310 that are close to each other. The backrest 320 is disposed on the rotating shaft 330. A power source 340 for driving the rotating shaft 330 to rotate, thereby folding or unfolding the backrest 320, may also be provided on the backrest 320.

[0050] The working principle of the sinkable seat frame provided in this application embodiment is as follows: (Refer to...) Figure 1This represents the normal operating state of the seat frame. When the seat frame needs to be folded, the telescopic motor 141 is activated, driving the push plate 260, which in turn moves the seat cushion frame 200. This causes the sliding member 250 to slide from the higher end to the lower end of the slide rail 111. Simultaneously, the crank 240 swings clockwise forward, causing the seat cushion frame 200 to move forward and downward. (Refer to...) Figure 7 This is a structural diagram of the seat frame in a folded or lowered state.
