Description

Technical Field

[0001] The invention relates to the technical field of construction, and in particular to a window-pushing assistant. Background Art

[0002] In traditional window design, windows are mostly opened and closed manually by pushing and pulling. However, in many window usage scenarios, obstacles are placed next to the windows. For example, most kitchen windows are placed next to the stove. When the windows need to be opened or closed, users often need to lean over to push and pull the windows, which is very inconvenient to operate. In addition, the windows cannot be opened at a large angle, which reduces the ventilation effect.

[0003] At present, there are also some window openers on the market for assisting window opening, but this type of window opener first requires a groove to be opened on the window sash, and when the window is closed, the driving rod is also exposed to the outside, which is not beautiful enough. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a window pushing assistant in view of the deficiencies of the above-mentioned prior art. A quadrilateral connecting rod structure is formed at the hinged ends of the first support rod, the second support rod and the output push rod, so that the window pushing swing rod and the output push rod are always parallel. The instability of the quadrilateral structure is utilized, that is, after the lengths of the four sides of the window pushing swing rod, the first support rod, the second support rod and the output push rod are fixed, their angles can still change. By utilizing this feature, the window pushing telescopic mechanism can achieve the characteristics of deformation, flexible telescopic travel and large travel, so as to conveniently solve the problems of insufficient window opening angle and troublesome window opening and closing. At the same time, in the closed state, the quadrilateral connecting rod structure will not be exposed too much, thereby improving the aesthetics of the product.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a window-pushing auxiliary device, comprising a fixed base plate installed on the window frame and a window sash fixing member installed on the window sash, characterized in that: a window-pushing swing rod is provided on the fixed base plate, one end of the window-pushing swing rod is connected to a driving assembly, and the other end is connected to a window-pushing telescopic mechanism, the window-pushing telescopic mechanism comprises a first support rod, a second support rod and an output push rod, one end of the output push rod is hinged to the window sash fixing member, and the other end is hinged to the first support rod and the second support rod respectively, one end of the window-pushing swing rod is opened and closed with the fixed base plate as a fulcrum through the driving assembly, and the other end is hinged to the first support rod and the second support rod respectively, and forms a quadrilateral connecting rod structure with the hinged ends of the first support rod, the second support rod and the output push rod, and the window-pushing swing rod is always parallel to the output push rod.

[0006] The above technical scheme is adopted, by installing a fixed base plate on the window frame, and arranging a push-window swing rod driven by a driving assembly on the fixed base plate, so that the push-window swing rod pushes the window sash to open and close. Since the length of the push-window swing rod affects the opening and closing angle of the window sash, a too long push-window swing rod is not conducive to opening and closing and is also not beautiful. Therefore, a push-window telescopic mechanism is arranged between the push-window swing rod and the window sash, so that the push-window swing rod can drive the output push rod to open and close the window sash by being hinged with the first support rod and the second support rod, and a quadrilateral connecting rod structure is formed at the hinged end of the first support rod, the second support rod and the output push rod, so that the push-window swing rod and the output push rod are always parallel, and the instability of the quadrilateral structure is utilized, that is, after the lengths of the four sides of the push-window swing rod, the first support rod, the second support rod and the output push rod are fixed, the angle thereof can still be changed, and this feature is utilized to enable the push-window telescopic mechanism to achieve the characteristics of deformation, flexible telescopic travel and the like, conveniently solving the problems of insufficient window opening angle and troublesome window opening and closing, and at the same time, in the closed state, the quadrilateral connecting rod structure will not be exposed too much, thereby improving the aesthetics of the product.

[0007] The above-mentioned window pushing assistant can be further configured as follows: the driving component includes a mounting column arranged on a fixed base plate, a window pushing gear arranged on a window pushing swing rod, a driving gear meshing with the window pushing gear, and a hand crank for driving the driving gear to rotate; the window pushing swing rod is sleeved on the mounting column, and the window pushing swing rod is driven by the hand crank to swing with the mounting column as a fulcrum.

[0008] By adopting the above technical solution, a mounting column is set on the fixed base plate, and the window push swing rod is mounted on the mounting column and swung by gear transmission. The window push swing rod is driven by a hand crank to swing with the mounting column as a fulcrum to complete the opening and closing of the window, conveniently solving the problem of insufficient window opening angle and troublesome window opening and closing.

[0009] The above-mentioned window pushing assistant can be further configured as follows: the driving component includes a driving motor arranged at one end of a fixed base plate, the driving end of the driving motor is connected to the window pushing swing rod, and drives the window pushing swing rod to swing with the driving motor as a fulcrum.

[0010] By adopting the above technical solution, when the driving component is a driving motor, the driving motor can drive the window push rod to swing with the output end of the driving motor as the fulcrum, thereby realizing electric opening and closing of the window. Remote starting can solve the problem of insufficient window opening angle and troublesome window opening and closing.

[0011] The above-mentioned window pushing auxiliary device can be further configured as follows: the first support rod and the second support rod have the same shape, the hinge point between the first support rod and the window pushing swing rod is a, and the hinge point between the first support rod and the output push rod is b, the hinge point between the second support rod and the window pushing swing rod is c, and the hinge point between the second support rod and the output push rod is d, and the distance from the hinge point a to the hinge point c is equal to the distance from the hinge point b to the hinge point d.

[0012] By adopting the above technical solution, by setting the distance from the hinge point a to the hinge point c and the distance from the hinge point b to the hinge point d to be equal, and the window push rod and the output push rod are always parallel, it can be concluded that the distance between the first support rod and the second support rod is the same, and it is concluded that the window push telescopic mechanism and the window push rod form a parallelogram, and the polymorphism of the parallelogram, that is, when the side length of the parallelogram is fixed, its angle can be changed to form countless parallelograms with the same side length but different angles, and the instability of the parallelogram means that the side length of the parallelogram is determined, but its shape and size cannot be completely determined, so as to realize a structure in which the distance between opposite sides is not changed, and complete the function of pushing and closing the window.

[0013] The above-mentioned window-pushing assistant may be further configured as follows: a driving box body for accommodating the driving component is provided on the fixed bottom plate.

[0014] By adopting the above technical solution, the drive box body is provided to cover the drive assembly, thereby improving the aesthetics of the product and preventing the drive assembly from being affected by external factors (dust, water) during operation, thereby improving the stability and service life of the product.

[0015] The above-mentioned window-pushing auxiliary device can be further configured as follows: the fixed bottom plate outer cover is provided with a window-pushing shell with an open end, and its open end faces one end of the window sash, and the window-pushing shell is provided with a accommodating cavity for accommodating the window-pushing swing rod and the window-pushing telescopic mechanism.

[0016] By adopting the above technical solution, a window push shell is provided to wrap the parts on the fixed bottom plate, so that the window push swing rod and the window push telescopic mechanism are hidden by the window push shell, thereby improving the aesthetics of the product.

[0017] The above-mentioned window pushing auxiliary device can be further configured as follows: the window pushing swing rod and the output push rod are in the same horizontal plane, the first support rod and the second support rod are in the same horizontal plane, the end at which the first support rod is hinged to the output push rod is provided with a first yielding arc portion bent from the end surface of the hinge point d to the hinge point b, and the end at which the second support rod is hinged to the window pushing swing rod is provided with a second yielding arc portion bent from the end surface of the hinge point a to the hinge point c.

[0018] By adopting the above technical solution, by setting the first yielding curved portion and the second yielding curved portion, when the window pushing auxiliary device is in the closed state, the first support rod is parallel to the hinged end of the window pushing rocker rod, the first yielding curved portion avoids the hinge point d and is connected to the hinge point b, the second support rod is parallel to the hinged end of the output push rod, and the second yielding curved portion avoids the hinge point a and is connected to the hinge point c, so that the window pushing auxiliary device is made into a quadrilateral structure requiring two overlapping layers, which can realize pushing and closing the window, and the first and second support rods in the closed state give way to each other, so as to avoid the push rod of the window pushing auxiliary device being exposed to the outside, thereby improving the aesthetics of the product.
