Description

Forward type support module and sofa Technical Field The utility model relates to the field of furniture, in particular to a forward support module and a sofa. Background Compared with the traditional sofa with single function, the multifunctional sofa is popular in recent years, the multifunctional sofa comprises a seat component, a backrest component and a leg support component, a mechanical stretching component for realizing sofa state conversion is arranged below the seat component, the mechanical stretching component is of a multi-link structure with a complex structure, and when the mechanical stretching component moves, the seat component, the backrest component and the leg support component are switched to different postures under the driving of the whole mechanical stretching component, so that the requirements of users are met. When the mechanical stretching assembly is stretched and opened, the back supporting assembly is linked to be leaned back, so that the multifunctional sofa is transited from the TV posture to the lying posture, but in the process of changing the multifunctional sofa from the sitting posture to the TV posture, the leg supporting assembly which rotates forwards can lead to the gravity center of the sofa to move forwards, the forward leaning phenomenon is very easy to occur, and the safety of the sofa and the use experience of a user are affected. For example, CN218889475 discloses a functional sofa stretching device with anti-forward-leaning mechanism, which comprises a supporting mechanism, the supporting mechanism comprises a sliding block, a supporting sleeve and a supporting rod, the leg supporting component moves to drive the supporting rod to rotate and move towards the direction close to the ground, the supporting rod is close to the ground in the process of opening the sofa, and the supporting rod is driven to support on the ground when the sofa leans forward, but the supporting mechanism is fixedly arranged on a seat frame iron frame and is only suitable for specific mechanical stretching components, and the universality is low. In the prior anti-toppling sofa patent with the publication number of CN117582085, a movable supporting component independent of a mechanical stretching component is arranged on a sofa armrest, the movable supporting component comprises a mounting seat, a movable component moving along the mounting seat and supporting legs linked with the movable component, a gear is rotationally connected to the mounting seat, the upper part of the gear and the upper part of the supporting legs are kept relatively fixed in the circumferential direction, one end of the movable component is provided with a rack meshed with the gear in a transmission manner, the movable component moves along the mounting seat and drives the gear to rotate after being triggered, so that the supporting legs are opened towards the direction of supporting the ground, and the movable supporting component is in a modularized design, so that the movable supporting component can be adapted to most multifunctional sofas on the premise of not being influenced by the structure of the mechanical stretching component, and the universality of the movable supporting component is improved. However, the support legs are opened in a rotating way, and the support positions of the support legs which are opened in a rotating way are influenced by the rotating radius, so that the contact positions of the support legs which are opened in a rotating way and the ground are not enough forward, and the stability effect of the sofa is influenced. Disclosure of Invention The utility model provides a forward support module and a sofa, wherein the forward support module is independent of the outside of the sofa, and a sliding component on a base and a support rod form linkage connection capable of rotating forwards and backwards, so that the sliding component can drive the support rod to be opened in a more forward state when sliding forwards, and the forward support module is arranged on the sofa, so that the forward support rod can be supported on the ground when the sofa is switched from a sitting posture to a TV posture, and the stability of the sofa is improved. The technical scheme of the utility model is realized as follows: The forward type support module comprises a base and a support assembly, wherein the support assembly comprises a sliding assembly and a support rod, the sliding assembly comprises a driving sliding piece and a driven sliding piece which are connected to the base in a sliding manner along the front-back direction, the support rod can be connected between the driving sliding piece and the driven sliding piece in a linkage manner in a front-back rotation manner, and the support rod can be linked to rotate back and forth when relative displacement occurs between the driving sliding piece and the driven sliding piece; The support rod can be sequentially switched to a forward moving st
