Description

Technical Field

[0001] This utility model relates to the field of lifting window frame technology, specifically a lifting window frame for RVs. Background Technology

[0002] RV-specific lift-up window frames are modular structures integrated into the side walls of RVs. An electric lifter drives the window to move back and forth between the visible and concealed window areas. The window frame uses a portal frame structure, assembled from at least three aluminum profiles connected by clips or bolts to form a detachable module. However, traditional RV window frame designs often employ multi-stage transmissions: motor → gears → ropes / chains → window body. Gear clearances and rope elastic deformation accumulate errors, causing misalignment between the window body and the sealing strip after lifting, leading to sealing failure. Furthermore, these designs occupy a large amount of space, encroaching on the limited interior space and affecting both aesthetics and functionality. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 As shown, this utility model is a special lifting window frame for RVs, including a window frame body 1 and a glass window 2. A precision lifting mechanism 3 is provided between the window frame body 1 and the glass window 2. The precision lifting mechanism 3 includes a fixed seat 31 fixedly connected to the inner bottom wall of the window frame body 1 and a support seat 32 fixedly connected to the bottom of the glass window 2. Four first connecting strips 33 are rotatably connected to the fixed seat 31. A connecting block 34 is fixedly connected to the bottom of the support seat 32. Four second connecting strips 35 are rotatably connected to the connecting block 34. The two first connecting strips 33 on the left side and the two adjacent second connecting strips 35 are rotatably connected. A movable block 36 is provided. A fixed block 37 is rotatably connected between the two second connecting bars 35 on the right side and between the two adjacent second connecting bars 35. A motor 38 is fixedly connected to the inner wall of the fixed block 37. The motor 38 is a servo geared motor, which can precisely control the speed and rotation angle of the output shaft to ensure high precision in raising and lowering the window. Its output shaft has a locking function; locking the output shaft after raising and lowering ensures the stability of the window. Simultaneously, its output shaft has a reversing function; reversing the output shaft controls the window to open and lower. The motor 38 is electrically connected to an external power source and is controlled by an external program. A transmission screw 39 is fixedly connected to the output end of the motor 38. By setting a precise window raising mechanism 3, hidden inside the inner wall of the window frame body 1, precise driving is achieved, freeing up more space inside the RV for seating, storage, or activity areas. At the same time, high-precision driving allows for more accurate control of the height of the raised and lowered window 2.

[0023] A trigger rod 4 is fixedly connected to the top of the glass window 2, and a trigger sealing mechanism 5 is provided on the inner wall of the window frame body 1. By setting the trigger sealing mechanism 5 to trigger and control the inflation filling, the airtightness can be guaranteed when the window is completely closed.

[0024] The trigger sealing mechanism 5 includes an automatic inflation / deflation pump 51 fixedly connected to the inner wall of the window frame body 1. The automatic inflation / deflation pump 51 is the core component of a RV-specific lift window frame. When the window is closed, the trigger rod 4 touches the trigger button 53, activating the automatic inflation / deflation pump 51 and inflating the sealing strips 52 on both sides. After the sealing strips 52 expand, they fill the gap between the glass window 2 and the inner wall of the window frame body 1, forming an airtight barrier that effectively blocks rainwater, dust, and noise, while also improving thermal insulation performance. When the window is opened, the trigger rod 4 leaves the trigger button 53, and the automatic inflation / deflation pump 51 reverses its direction, extracting the gas from the sealing strips 52 and causing them to contract back to their original state. The trigger button 53 is a pressure switch that transmits a signal to the control unit, which then drives the pump 51. The automatic inflation / deflation pump 51 is electrically connected to an external power source. Sealing strips 52 are connected to both sides of the automatic inflation / deflation pump 51, and a trigger button 53 is located at the bottom of the pump 51.

[0025] The glass window 2 is slidably connected to the inner wall of the window frame body 1, and both sealing strips 52 are adapted to the inner wall of the window frame body 1.

[0026] The transmission screw 39 and the moving block 36 are threaded together. The inner wall of the moving block 36 is provided with a threaded groove that matches the transmission screw 39. The lengths of the four first connecting bars 33 and the four second connecting bars 35 are the same.

[0027] Four first connecting bars 33 and four second connecting bars 35 are symmetrically distributed between the connecting block 34 and the fixing seat 31.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] The working principle of this utility model is as follows: First, the starter motor 38 is controlled to drive the transmission screw 39 at the output end to rotate. When the transmission screw 39 rotates, it drives the moving block 36, causing the moving block 36 to move to the right along the surface of the transmission screw 39. When the moving block 36 moves, it squeezes and drives the connecting block 34 through the two adjacent left second connecting bars 35, and rotates on the fixed base 31 through the two left first connecting bars 33. The squeezing action of the two left second connecting bars 35 causes the connecting block 34 to rotate on the fixed block 37 through the two right second connecting bars 35, and squeezes the fixed block 37, causing the fixed block 37 to rotate on the fixed base 31 through the two right first connecting bars 33. At the same time, it supports... The support 32 moves upward in a straight line. When the support 32 moves, it drives the glass window 2 to move upward inside the window frame body 1 to achieve the window closing operation (controlling the start motor 38 to reverse its output shaft can achieve the window opening operation). When the window is closed, the trigger rod 4 at the top of the glass window 2 touches and presses the trigger button 53, which causes the automatic inflation and deflation pump 51 to start and inflate the two sealing strips 52 of the window frame body 1. This allows the two sealing strips 52 to fit and fill the space between the glass window 2 and the inner wall of the window frame body 1 to achieve a seal. (When the window is closed, the trigger rod 4 leaves and releases the press of the trigger button 53, which allows the automatic inflation and deflation pump 51 to control the sealing strips 52 to deflate.)
