Hybrid power assisting system of lifting window

Abstract

The invention discloses a hybrid power assisting system of a lifting window. The hybrid power assisting system comprises a window frame, a window sash, driving mechanisms, air spring power assisting mechanisms and balancing weight power assisting mechanisms; the window sash capable of being opened is arranged on the window frame, the driving mechanisms for driving the window sash to be opened and closed are arranged in the window frame on the two sides of the window sash, and the two air spring power assisting mechanisms are arranged in the top of the window frame; the two air spring power assisting mechanisms are opposite in orientation, and the two air spring power assisting mechanisms distributed along the opposite corners of the window sash and connected to the side wall of the window sash; and the balancing weight power assisting mechanisms are further arranged at the tops of the two sides of the window frame and connected to the other opposite corners of the window sash. According to the hybrid power assisting system, by adopting the balance weight scheme of combining the air spring power assisting mechanisms and the balancing weight power assisting mechanisms, the space in the window frame can be saved, the situation that attractiveness is affected due to the fact that the size of the window frame is increased is prevented, and meanwhile the balance weight of air springs can be reduced, so that balance weight errors caused by temperature difference are reduced, therefore, the counterweight ratio of a heavy window sash is ensured to be within the normal load range of a driving electric motor, and the normal operation of the window sash is ensured.

technical field [0001] The invention relates to the field of lift window boosting, in particular to a lift window hybrid boosting system. Background technique [0002] The window sash is the main channel for indoor ventilation and light transmission. For this reason, the size of the existing window sash is relatively large, and the corresponding weight is also relatively heavy. However, the increase in the weight of the window sash also brings some other problems, such as being too heavy and inconvenient to open and close. , Difficulty in installation and debugging, etc. In order to reduce the self-weight of the existing window sash, most of the counterweights are used to reduce the self-weight of the window sash, that is, the window sash is assisted, and the counterweight method mainly includes counterweight counterweight or gas spring counterweight, because the counterweight will occupy the size of the window frame , causing the thickness of the window frame to increase, ...

Problems solved by technology

[0002] The window sash is the main channel for indoor ventilation and light transmission. For this reason, the size of the existing window sash is relatively large, and the corresponding weight is also relatively heavy. However, the increase in the weight of the window sash also brings some other problems, such as being too heavy and inconvenient to open and close. , installation and debugging difficulties, etc.

In order to reduce the self-weight of the existing window sash, most of the counterweights are used to reduce the self-weight of the window sash, that is, the window sash is assisted, and the counterweight method mainly includes counterweight counterweight or gas spring counterweight, because the counterweight will occupy the size of the window frame , causing the thickness of the window frame to increase, which affects the appearance of the window sash, so the existing window sash weights mostly use gas springs

However, the gas spring itself has the following problems: 1. However, when the length of the gas spring is extended and retracted, its strength is unequal, and the strength of the gas spring itself is unequal. And the elastic force of the gas spring when it returns to the free state from the compressed state and the free state is different by 5cm, that is, the use of the gas spring is not equal to the force of the direction of movement and the distance of movement

Therefore, the use environment of the existing gas spring is mainly the hanging window, that is, the top of the window is hinged with the window frame, and the environment in which the lower part of the sash is opened by pushing out. One hinge point, these two hinge points can be decomposed to make the force of the gas spring tend to be equal, but the application of the gas spring and the lifting window will cause the counterweight ratio of the lifting window to be inconsistent; 2. The force of the gas spring There is still a 10-20% deviation, that is, the distribution of the elastic force of a 100kg gas spring is within the range of 80-120kg, while the distribution range of the elastic force of a 300kg gas spring is larger, resulting in large and heavy lifting windows. The load range of the motor is large; 3. There is temperature drift in the gas spring, that is, the force value of the gas spring of the same specification is different under different ambient temperatures, which makes it inconvenient to control the weight of the gas spring; 4. The gas spring The elastic force distribution is uneven during linear motion, resulting in unstable force values. The specific performance is that only a small force is required to compress the gas spring in the early stage of compression, and a large force is required to compress the gas spring in the late stage of compression.

The above problems will seriously affect the counterweight of the gas spring to the heavy-duty lift window. Due to the structure of the heavy-duty lift window, the gas spring can only move in a straight line when the gas spring is used, and it will directly act on the motor, resulting in an increase in the load range of the motor. Large, affecting the stability of the motor operation
