Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent home drive flipping, and in particular relates to a power reversing transmission pair mounting structure and an electric flip cover driver. Background Art

[0002] In today's society, the smart home sector is experiencing unprecedented rapid development. A wide variety of smart home appliances are popping up like mushrooms after rain, significantly enriching the market and improving consumers' quality of life. Among them, smart toilets, as a key component of smart home products, are experiencing particularly rapid growth and are highly sought after by consumers.

[0003] One of the core functions of smart toilets is automatic lid opening, a convenient feature that greatly enhances the user experience. Currently, smart toilets on the market generally use electric lid actuators to achieve this function. However, due to internal space constraints, the actuators must be relatively compact, placing stringent requirements on the design and mounting structure of the motor and transmission.

[0004] In mechanical transmission systems, the connection method between the motor output and the power supply has a significant impact on overall system performance and space utilization. Traditionally, the motor is typically connected directly to the drive shaft or installed parallel to the drive shaft. However, both connection methods have limitations.

[0005] While direct motor connection is simple and straightforward, it often results in the motor and transmission axis aligning, making the overall structure larger in one direction and taking up more space. This is particularly disadvantageous in space-constrained applications.

[0006] On the other hand, while installing the motor parallel to the drive shaft reduces the axial dimension to a certain extent, it still requires a larger installation space and a complex support structure to maintain stable motor operation. Furthermore, this installation method may increase energy loss and noise during the transmission process, affecting the overall performance of the system.

[0007] In traditional mechanical transmission, worm gear reducers, as part of a reversing transmission pair, are widely used in various mechanical equipment due to their high reduction ratio, compact structure, and high transmission efficiency. However, the traditional worm gear installation method typically uses a vertical axis layout, which has certain limitations in practical applications.

[0008] Specifically, when using the same model motor and worm gear, the vertical mounting method means the motor occupies a larger vertical space, which often fails to meet the design requirements of some space-critical applications. This is especially true in applications that require optimized layout and increased space utilization, where traditional vertical mounting becomes particularly inconvenient and can even become a design bottleneck.

[0009] Therefore, in order to solve this problem, the utility model proposes a power reversing transmission pair installation structure and an electric flip cover driver. Utility Model Content

[0010] To address the challenges of existing technologies, the present invention provides a power reversing transmission pair mounting structure and an electric flip lid actuator that achieve powerful output torque within a compact footprint. By designing a reversing gear pair, this electric flip lid actuator changes the traditional motor mounting method, enabling a more flexible and space-efficient connection between the motor and the transmission system. This approach effectively reduces the vertical space occupied by the motor, improving space utilization and addressing a wider range of space-critical applications.

[0016] Advantages and technical effects of the utility model: The power reversing transmission pair mounting structure and the electric flip cover driver provided by the utility model have significant and diversified technical effects, which are mainly reflected in the following aspects:

[0017] First, by using a worm gear as the reversing transmission pair, the drive achieves a high reduction ratio and high torque output, enabling efficient transmission within a limited space. This feature is particularly important in applications requiring high torque drive and limited space.

[0018] Secondly, the application of tilted mounting significantly improves space utilization, making the layout of the motor and transmission components more compact. This design reduces overall size and weight, increases design flexibility, and enables the drive to better adapt to various installation environments.

[0019] Further optimized technical features also bring significant technical benefits.

[0020] In addition, the optimized structural layout and space utilization make the overall structure more compact, simplifying the installation process and improving assembly efficiency. The improved transmission efficiency and precision ensure the efficient operation and precise control of the drive.

[0021] Finally, the overall structural design also takes into account ease of maintenance and servicing. For example, the shaft head press-fit on the rear end cover allows the shaft head of the worm gear to remain in the shaft head installation slot, ensuring transmission stability while facilitating removal and replacement when necessary.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] See 1 and Figure 2A power reversing transmission pair installation structure includes a motor 1 and a reversing transmission pair 2 connected to the motor output shaft, wherein the reversing transmission pair is a worm gear transmission pair composed of a worm wheel 2-1 and a worm 2-2; the angle between the vertical plane where the axis direction of the motor shaft of the motor is located and the plane where the vertical center line of the worm wheel is located is 0-45 degrees, and the motor is located below the worm wheel, and the output shaft of the motor is connected to the worm.

[0034] Technical Effect Analysis of the Power Reversing Transmission Pair Installation Structure

[0035] 1. Technical effect of using worm gear as reversing transmission pair

[0036] High reduction ratio and high torque output: The worm gear transmission pair, with its unique meshing method, can achieve a large reduction ratio, allowing the motor to run at a higher speed. At the same time, the worm gear transmission pair reduces the speed and outputs greater torque. This is particularly important for applications requiring high torque drive scenarios.

[0037] Compact structure: The worm gear transmission pair has a relatively compact structure, which can achieve efficient transmission in a limited space. This feature makes the worm gear transmission pair an ideal choice for space-constrained applications.

[0038] Self-locking: Some worm gear pairs have a self-locking feature. This means that when the worm's lead angle is less than the worm-gear friction angle, the worm can actively drive the worm wheel, while the worm wheel cannot reversely drive the worm. This feature is very useful in some situations where reverse transmission is required.

[0039] Self-aligning performance: The worm gear transmission pair also has a certain self-aligning performance and can adapt to certain axial and radial deviations, thereby simplifying the installation and adjustment process and improving assembly accuracy and efficiency.

[0040] 2. Technical Effects of Inclined Worm Gear Installation Compared with Traditional Vertical Installation

[0041] Improved space utilization: In traditional vertical installation, the motor and worm gear pair are typically aligned along the same vertical axis, occupying a large amount of vertical space. However, with an inclined installation, the motor shaft is tilted relative to the worm gear centerline, with the motor positioned below the worm gear. This significantly reduces the vertical space occupied by the motor and improves space utilization. This is particularly important for space-constrained equipment or systems, reducing overall size and weight and increasing design flexibility.

[0042] Optimizing Transmission Efficiency: While tilted mounting itself has a limited direct impact on transmission efficiency, proper design and calculation can ensure that the worm gear pair maintains good lubrication and cooling conditions, thereby maintaining high transmission efficiency. Furthermore, tilted mounting helps reduce the additional friction and energy loss that can sometimes be caused by improper installation.

[0043] Easy installation and maintenance: The tilted installation makes it easier to access and maintain some previously difficult-to-access components (such as the lubrication points of the worm gear). This helps reduce maintenance costs and time, and improves the reliability and service life of the equipment.

[0044] Increased adaptability and flexibility: Tilt mounting increases design flexibility, allowing designers to select the optimal mounting angle and layout based on specific application scenarios and space constraints. This flexibility helps meet diverse design needs and market changes.

[0045] In summary, the use of a worm gear as a reversing transmission pair, combined with an inclined mounting method, not only achieves efficient transmission and torque output, but also significantly improves space utilization, optimizes transmission efficiency, enhances installation and maintenance convenience, and improves design adaptability and flexibility. These technical benefits make this mounting structure promising for broad application in a variety of mechanical equipment and systems.

The worm wheel of the reversing transmission pair is installed in the housing through a worm wheel support shaft 2-3. The worm gear transmission pair preferably has a worm gear transmission pair with a reduction function; the reduction gear 4 includes at least a first-stage reduction gear pair. The input pinion 4-1 of the first-stage reduction gear pair is installed on the worm wheel support shaft 2-3, and the final-stage output gear 4-2 of the reduction gear is connected to the power output shaft. Depending on actual needs, the reduction gear can be single-stage, double-stage, or triple-stage. The technical benefits of the electric clamshell actuator using a worm gear as a reversing transmission pair combined with an inclined mounting method are primarily reflected in the following aspects: First, the worm gear transmission pair, with its high reduction ratio and high torque output, enables the electric clamshell actuator to achieve efficient transmission within a limited space. Second, the inclined mounting method significantly improves space utilization, making the layout of the motor and transmission components more compact, reducing overall size and weight, and increasing design flexibility.

A worm shaft head mounting groove 3-70 is provided; the center of the worm shaft head mounting groove and the first arc-shaped support groove are in the same straight line; a shaft head pressing portion 3-20 is provided on the rear end cover 3-2 at the position corresponding to the worm shaft head mounting groove, so that the shaft head of the worm is kept in the shaft head mounting groove.

This design not only provides additional support for the motor, but also effectively utilizes the space of the rear end cover, making the overall structure more compact.

[0055] After the rear end cover is fixedly connected to the housing, the motor is firmly fixed in the power source chamber. This integrated design simplifies the installation process and improves assembly efficiency.

[0056] Improved transmission efficiency and precision:

[0057] The design of the worm gear support rear axle seat and the worm gear support front axle seat ensures the stable installation and precise positioning of the worm gear support shaft, reduces deviation and friction during transmission, and thus improves transmission efficiency and precision.

[0058] Convenient maintenance and care:

[0059] The overall structure is designed with ease of maintenance and upkeep in mind.
