Description

Technical Field

[0001] This utility model belongs to the technical field of window push-window motor equipment, specifically relating to a window push-window motor. Background Technology

[0002] In the field of modern building automation and smart home, electric window opening systems are widely used in commercial buildings, rail transit stations, large factories, and smart homes due to their convenience and intelligent advantages. As the core power component of the system, the structural design of the window opening motor directly affects installation convenience, operational stability, space utilization, and manufacturing costs. Therefore, its compactness, structural simplification, and reliability are extremely important. Currently, window opening motors on the market are mainly divided into linear and rotary types. Both have significant structural design flaws, making it difficult to meet the requirements of "small size, high integration, and easy assembly." Linear window opening motors convert rotary motion into linear motion of the push rod through a motor-driven lead screw, gear rack, and other structures. Existing products require independent motor, reduction, transmission, and guide components, with each component fixed by complex connectors, resulting in a fragmented and bulky overall structure that is difficult to adapt to scenarios with limited installation space. Furthermore, the dispersed design of multiple components increases the number of parts and assembly difficulty, requiring repeated calibration of coaxiality; otherwise, transmission jamming and noise problems can easily occur. Moreover, after long-term operation, loose connectors can lead to decreased transmission accuracy or even push rod jamming. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems by providing a window pusher motor.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A window push-opening motor includes a motor housing with an inner cavity. The motor housing has an axially distributed motor cavity and a power output cavity. A motor transmission assembly is installed in the motor cavity. A lead screw body connected to the motor transmission assembly is axially rotatably inserted into the power output cavity. A lead screw nut seat threadedly connected to the lead screw body is fitted onto the lead screw body. A sliding platform located outside the power output cavity and extending axially along the motor housing has a sliding platform on one side. A motor power output block is axially movably mounted on the sliding platform. The lead screw nut seat is connected to the motor power output block through a connecting structure penetrating one side of the sliding platform. The motor cavity facilitates the placement of the motor transmission assembly, and the power output cavity facilitates the placement of the lead screw body. The lead screw nut seat is movably mounted through the threaded lead screw body. The lead screw nut seat is fixedly connected to the motor power output block through a connecting structure, which improves structural compactness and reduces space occupation. Furthermore, the lead screw nut seat can drive the motor power output block to slide synchronously on the sliding platform during the sliding process of the lead screw body. The motor power output block facilitates the control of the window opening state.

[0005] In the aforementioned window push motor, the motor transmission assembly includes a cylindrical motor transmission housing disposed within the motor cavity. A motor body is located on the inner side of one end of the motor transmission housing, and the motor body is connected to a planetary gear set located on the inner side of the other end of the motor transmission housing. The motor transmission housing provides good protection for the motor body, and the planetary gear housing on the outer circumferential side of the planetary gear set provides protection for the planetary gear set, thereby improving the service life of the motor body and the planetary gear set.

[0006] In the aforementioned window pusher motor, a partition seat is provided on the inner side of the middle part of the motor housing, and the power output cavity and the motor cavity are respectively located on both sides of the partition seat. One end of the lead screw passes through the partition seat and is connected to the output end of the planetary gear set through a coupling. The other end of the lead screw is rotatably connected to the bearing at the end of the power output cavity away from the motor cavity. The coupling enables the planetary gear set to drive the lead screw to rotate synchronously through the output end. The oil-impregnated bearing and bearing can improve the support and lubrication effect of the lead screw, ensure the rotational stability of the lead screw, and ensure the displacement accuracy of the lead screw on the lead screw nut seat.

[0007] In the aforementioned window sliding motor, the lead screw nut seat is rectangular in shape, the lead screw body axially penetrates the lead screw nut seat, and the upper and lower sides of the lead screw nut seat slide in contact with the inner sides of the motor housing, respectively; the motor power output block has grooves at both ends, and the lower end of the motor power output block is provided with a pad that slides in contact with the sliding platform. The grooves facilitate the connection between the motor power output block and the window control, and the pad reduces the sliding friction between the motor power output block and the sliding platform, ensuring the smooth sliding of the motor power output block on the sliding platform.

[0008] In the aforementioned window pusher motor, one side of the sliding platform has a strip-shaped groove that is connected to the power output cavity and extends axially along the motor housing. The sliding platform is also provided with a dustproof component that can cover the strip-shaped groove. The strip-shaped groove facilitates the motor power output block to be fixedly connected to the lead screw nut seat through a connecting structure. The dustproof component can also prevent dust from entering the power output cavity, ensuring the displacement accuracy of the lead screw nut seat.

[0009] In the aforementioned window pusher motor, the connection structure includes several vertical slots sequentially arranged on one side of the lead screw nut seat. Each vertical slot is connected to one end of a sliding bracket by mounting bolts. The sliding brackets pass vertically through the strip-shaped slots and are integrally formed on one side of the lower end of the lead screw nut seat. The vertical slots and sliding brackets facilitate the fixed connection between the motor power output block and the lead screw nut seat, ensuring the connection stability between the motor power output block and the lead screw nut seat.

[0010] In the aforementioned window sliding motor, the dustproof component includes a dustproof rubber pad. The dustproof rubber pad extends axially along a strip-shaped slide groove, and one side of the dustproof rubber pad has a flexible covering portion that covers the strip-shaped slide groove. The other side of the dustproof rubber pad has a pad mounting portion with a T-shaped cross-section. The pad mounting portion is installed in a strip-shaped mounting groove located on the side of the strip-shaped slide groove away from the sliding platform. The strip-shaped mounting groove facilitates the installation of the dustproof rubber pad through the pad mounting portion, and the flexible covering portion covers the strip-shaped mounting groove to ensure a dustproof effect on the power output cavity.

[0011] In the aforementioned window push motor, the motor housing has a mounting boss on one side adjacent to the sliding platform. The sliding platform is concave, and the motor power output block does not extend beyond the outer side of the mounting boss. The mounting boss has a circuit board mounting structure. The mounting boss facilitates the installation of the motor board mounting structure, and the motor board mounting structure facilitates user control of the motor transmission components.

[0012] In the aforementioned sliding window motor, the circuit board mounting structure includes a circuit board mounting cavity disposed within a mounting boss and located outside the motor cavity. A circuit board body is disposed within the circuit board mounting cavity, and the motor cavity and the circuit board mounting cavity are connected via a wire hole. One side of the circuit board mounting cavity is open, and a cover plate that can close the openness is provided on the outside of the mounting boss via a sealing ring. The circuit board mounting cavity facilitates the installation of the circuit board body, and the wire hole facilitates the connection between the circuit board body and the motor drive assembly. The cover plate provides a sealing and protective effect for the circuit board mounting cavity, and the sealing ring further enhances the sealing effect and extends the service life of the circuit board body.

[0013] In the aforementioned window push motor, the motor housing is assembled from an upper housing and a lower housing arranged correspondingly above and below. The mounting boss and the sliding platform are both located on the side of the upper housing away from the lower housing. The motor drive housing is positioned between the upper housing and the lower housing by means of a shock-absorbing pad. The upper housing and the lower housing facilitate the installation of the motor drive assembly and the lead screw, and the shock-absorbing pad can reduce the vibration of the motor drive assembly during operation, thereby improving the stability of the motor drive assembly.

[0014] Compared with existing technologies, the advantages of this utility model are:

The lead screw nut seat 31 is movably set through the thread of the lead screw body 3. The lead screw nut seat 31 is fixedly connected to the motor power output block 4 through the connecting structure 5, which can improve the structural compactness and reduce the space occupied. During the sliding process of the lead screw nut seat 31 on the lead screw body 3, it can drive the motor power output block 4 to slide synchronously on the sliding platform 13. The motor power output block 4 can also facilitate the control of the window opening status.

[0027] Specifically, the motor drive assembly 2 includes a cylindrical motor drive housing 21 disposed inside the motor cavity 11. A motor body 22 is provided on the inner side of one end of the motor drive housing 21, and the motor body 22 is connected to a planetary gear set 23 located on the inner side of the other end of the motor drive housing 21.

[0028] The motor housing 1 has a partition seat 14 on its inner side in the middle, and the power output cavity 12 and the motor cavity 11 are located on both sides of the partition seat 14. One end of the lead screw 3 passes through the partition seat 14 and is connected to the output end 231 of the planetary gear set 23 via the coupling 6. A gearbox damping pad is fitted around the output end 231, which effectively reduces the vibration of the planetary gear set 23 during transmission and extends its service life. A coupling damping pad is also provided between the output end 231 and the coupling 6, which further reduces vibration. To minimize vibration during transmission and ensure transmission stability, the separator 14 has an oil-impregnated bearing sleeved on the outer circumference of the lead screw body 3.
