[0001] This application relates to the field of furniture technology, and in particular to a base assembly and a sofa seat. Background Technology
[0002] Currently, sofa base assemblies generally consist of a frame and a seat frame that is detachably connected to the frame. In existing sofas, the seat cushions are usually detachably connected to the seat frame for easy removal, cleaning, or replacement. However, traditional metal frames have U-shaped outward-curving edges, which can easily cause cuts when users remove the seat cushions, seriously affecting safety and user experience. Moreover, metal frames are more difficult to manufacture and require more expensive materials, which significantly increases manufacturing time and production costs. Utility Model Content
[0003] The purpose of this utility model is to disclose a base assembly and sofa seat, in which the cross-section of the seat frame is designed as a plane with closed edges, eliminating the possibility of users being cut when removing the seat cushion due to the outward turning of the traditional seat frame edges, greatly improving the safety of use and the user experience. Moreover, this structure can be directly formed by cutting and sanding solid wood seat frames, which not only greatly reduces the manufacturing difficulty of the seat frame, but also significantly reduces material costs, thus greatly shortening the manufacturing time and saving production costs.
[0004] To achieve the above objectives, this utility model discloses a base assembly, comprising:
[0005] A support frame, including a support bracket, a side plate for mounting guide rails, and a slider that can slide along the guide rails.
[0006] The seat frame has a connecting plate for hinged connection with the slider. The top surface of the seat frame is used to form a detachable connection with the bottom surface of the seat cushion. The cross-section of the seat frame is a plane with closed edges.
[0007] As an optional implementation, the rear end of the support frame is provided with a first support leg, the front end of the support frame is provided with a protrusion, and the bottom end of the protrusion is connected to a second support leg.

[0012] The foot pedal assembly is mounted on the front side of the seat frame. The moving end is hinged to the seat frame by hinge with the foot pedal assembly to drive the foot pedal assembly to extend and retract and drive the seat frame to slide.
[0013] As an optional implementation, the foot pedal assembly includes two telescopic legs and a connecting crossbar. The two telescopic legs are respectively installed at the front end of the seat frame, and the connecting crossbar is connected between the two telescopic legs. The movable end is hinged to the connecting crossbar.
[0014] As an alternative implementation, the foot pedal assembly also includes a spring disposed between the telescopic leg and the support frame to provide a force assisting in the retraction of the telescopic leg.
[0015] As an optional implementation, the motor assembly also includes a slide rail, which is fixed relative to the fixed end, and the movable end is slidably disposed on the slide rail so that the movable end can move along the slide rail.
[0016] As an optional implementation, it also includes:

[0043] Example 1:
[0044] Please see Figure 1-13 This application provides a base assembly for use in sofa seats, including a support frame 1 and a seat frame 2.
[0045] Specifically, the support frame 1 includes a support bracket 11, on which a side plate 15 for mounting a guide rail is provided, and a slider that can slide along the guide rail is provided; the seat frame 2 is provided with a connecting plate 21 for hinged connection with the slider, the top surface of the seat frame 2 is used to form a detachable connection with the bottom surface of the seat cushion, and the cross-section of the seat frame 2 is a plane with closed edge lines.
[0046] By setting the cut surface of the seat frame 2 as a plane with closed edges, the possibility of users being cut due to the outward turning of the edges of the traditional seat frame 2 when removing the seat cushion is eliminated, which greatly improves the safety of use and the user experience. Moreover, this structure can be directly formed by cutting and sanding solid wood seat frame 2, which not only greatly reduces the manufacturing difficulty of seat frame 2, but also significantly reduces material costs, which can greatly shorten the manufacturing time and save production costs.
[0047] Specifically, the rear end of the support frame 11 is provided with a first support leg 12, the front end of the support frame 11 is provided with a protrusion 13, and the bottom end of the protrusion 13 is connected to a second support leg 14. This support frame 11 structure is also made of wood to further reduce the manufacturing difficulty and production cost of the entire base assembly; more specifically, the rear end of the support frame 11 is provided with a crossbeam 10, and the first support leg 12 is provided on the bottom side of the end of the crossbeam 10.
[0048] Furthermore, the base assembly also includes a motor assembly 5, which includes a fixed end 51 and a movable end 52. The fixed end 51 is fixed to the crossbeam 10, and the movable end 52 is hinged to the seat frame 2. The movable end 52 can move relative to the fixed end 51. Furthermore, the base assembly also includes a foot pedal assembly 4, which is installed on the front side of the seat frame 2. The movable end 52 is hinged to the seat frame 2 by hinged to the foot pedal assembly 4, so as to drive the foot pedal assembly 4 to extend and retract and drive the seat frame 2 to slide.
[0049] Preferably, the foot pedal assembly 4 includes two telescopic legs 41 and a connecting crossbar 42. The two telescopic legs 41 are respectively installed at the front end of the seat frame 2, and the connecting crossbar 42 is connected between the two telescopic legs 41. The moving end 52 is hinged to the connecting crossbar 42. More preferably, the foot pedal assembly 4 also includes a spring 43, which is disposed between the telescopic legs 41 and the support frame 11 to provide an auxiliary force for the telescopic legs 41 to retract. In practice, the motor assembly 5 also includes a slide rail 53, which is fixed relative to the fixed end 51. The moving end 52 is slidably disposed on the slide rail 53 so that the moving end 52 moves along the slide rail 53. The fixed end 51 can be configured as a power motor, and the moving end 52 can be configured as a slide table. The moving end 52 can be hinged to the connecting crossbar 42 through a connecting rod. Specifically, one end of the connecting rod is hinged to the moving end 52, and the other end of the connecting rod is hinged to the connecting crossbar 42.
[0050] When the mobile end 52 pushes the telescopic leg 41 to extend, the seat frame 2 slides forward accordingly, thereby realizing the extended state of this base assembly; when the mobile end 52 pulls to retract, the seat frame 2 slides backward accordingly, and under the action of the spring 43, the telescopic leg 41 can retract more smoothly, and correspondingly, the seat frame 2 can also slide backward more smoothly, thereby realizing the retracted state of this base assembly.
