Description

Technical FieldThe invention relates to the field of accessories for door and window fittings and, more particularly, to a pop-up device with an optimized cushioning and cushioning structure for furniture.Background ArtOn Nov. 5, 2024, the applicant published Patent Document No. CN202420217423.8. The patent designation is a cushioning and cushioning structure of the furniture unfolding apparatus. A damper mechanism is separately mounted on the cabinet of the furniture unfolding apparatus. A damper, a slider, and front and rear adjusting members are mounted in the base body of the damper mechanism. Front and rear adjustment members drive the slide to move in the axial direction. And the slider drives the damper to move in the axial direction so that the damper abuts the main support arm and provides a damping action when the pop-up device is in the closed state;Although the damper mechanism is more convenient to install than the present door pop-up device and does not require too much space as a whole, there is a disadvantage: the effect of the damper mechanism is at the lower swing end of the main support arm. When a light cabinet door is used, the torque at the lower pivot end is low, which cannot balance the force of the damper, whereby the cabinet door is less dense in the closed state; therefore, further improvement is required.Content of the Utility ModelThe purpose of the present invention is to provide a pop-up device with an optimized cushioning and cushioning structure for furniture, which is characterized in the above-mentioned manner. Background Art To Solve Problems Raised.In order to achieve the above purpose, the utility model provides the following technical solutions:A pop-up device with an optimized cushioning and cushioning structure for furniture, comprising a housing, a support arm mechanism and a cushioning mechanism, the housing being arranged on the furniture body, the support arm mechanism being connected to the cabinet door and turning over with respect to the furniture body, the cushioning mechanism generating a cushioning force for the support arm mechanism when it is turned over and closed, the support arm mechanism comprising at least one main support arm, the upper end of the main support arm being hingedly connected to the housing, the center of the main support arm being provided at the top with an action point, the cushioning mechanism comprising a rotary seat a and a damper, the lower end of the rotary seat a being hingedly connected to the housing, the upper end of the rotary seat a being provided with an action part, the action point being in contact with the action part, when the main support arm is closed, one end of the damper is hinged to the housing, the other end acting on the pivot seat a, so that the damper provides a buffer force to the support arm mechanism.Preferably, the point of action is a transverse pin, the axial direction of the transverse pin being adjusted along the thickness direction of the main support arm.Preferably, the bottom surface of the action part is provided with a ramp.Preferably, a limiting column is arranged symmetrically at each end of the seat a remote from the articulation point, a corresponding limiting column being provided on the housing with an arcuate groove, the limiting column being slidably fitted with the arcuate groove.Preferably, the damper mechanism further comprises a transmission screw and a slider, the transmission screw being rotatably disposed in the rotational seat a, the threaded part being connected to the slider, the slider being linearly driven in the rotational seat a as the transmission screw rotates, the telescopic end of the damper being connected to the slider.Preferably, the transmission screw is provided with a driving part, the driving part being a gear structure.Preferably, a plug slot is provided on the slider, wherein a telescopic end of the damper is inserted into the plug slot, wherein the plug slot has a round table shape and guide ramps are provided above and below the opening of the plug slot.Preferably, the damper mechanism further comprises a swivel seat b, the swivel seat b being provided with a mounting cavity, the cylinder end of the damper being matched with the mounting cavity, the cylinder end of the damper being embedded in the mounting cavity, one end of the swivel seat b being rotatably connected to the housing such that the telescopic end of the damper swings along the pivot point.Preferably, the housing also comprises an elastic mechanism providing elastic force to the support arm mechanism and a force adjusting mechanism, wherein the central shaft of the force adjusting mechanism is connected to the housing and the upper swinging end of the force adjusting mechanism is hingedly connected to the support arm mechanism, wherein the lower swinging end of the force adjusting mechanism is hingedly connected to the elastic mechanism, wherein the force adjusting mechanism is used for adjusting elastic force provided by the elastic device to the support arm mechanism.Preferably, an angular cavity is formed between the support arm mechanism and the elastic mechanism and the force adjusting mechanism, the damper mechanism being disposed in the angular cavity.As compared with the prior art, the present technical solution provides a pop-up device with an optimized cushioning and cushioning structure for furniture: by having an action point at the center of the main support arm, the action point of the main support arm is applied to the action part of the swivel seat a when the support arm mechanism is turned over and closed, so that the damper hinged to the housing suppresses the action force of the support arm mechanism; in the utility model, the position of the action point is changed for matching with the swivel seat a and the damper, so that the cushioning force of the damper can be balanced when the support arm mechanism is turned over and closed, and it can be used on light doors to increase applicability.Illustration of the Accompanying DrawingsFIG. 1 is a schematic view of the main view of the open state in the present invention.
