Description

Technical Field

[0001] This utility model relates to the technical field of intelligent actuators, specifically to a compact intelligent actuator. Background Technology

[0002] Actuators are an essential component of automatic control systems. Their function is to receive control signals from the controller, change the magnitude of the controlled medium, and thus maintain the controlled variable at the required value or within a certain range. Actuators can be classified into three main categories according to their energy source: pneumatic, hydraulic, and electric. Electric actuators offer convenient energy access and rapid signal transmission, and are characterized by their large output thrust.

[0003] Chinese patent application CN202411578975.2, entitled "An Intelligent Control Actuator," discloses an intelligent control actuator that includes a housing, a motor, an output shaft, an input gear, an output gear, and a gear set. The gear set includes several sequentially meshing double gears. Common gear sets on the market are similar to those in the aforementioned patent. The several double gears are distributed in a curved or vortex pattern, which results in a large cross-sectional area of ​​the actuator, i.e., a long width or length. This is not conducive to use in narrow spaces. Therefore, a compact intelligent actuator needs to be designed. Utility Model Content

[0004] In view of the above-mentioned technical problems, the purpose of this utility model is to overcome the problem that the large size of the actuator in the prior art is not conducive to use in small spaces.

[0005] To achieve the above objectives, this utility model provides a compact intelligent actuator, which includes: a housing, an input gear, an output gear, and several double gears for connecting the output gear and the input gear. Each double gear is fitted with a rotating shaft mounted on the housing. The several double gears are arranged in a V-shaped stepped manner, and the double gear located at the tip of the V-shape is a pointed double gear, which is located at the lowest or highest point of the several double gears.

[0006] Preferably, the input gears are arranged close to each other.

[0007] Preferably, the actuator further includes a motor, the input gear is fixedly sleeved on the motor shaft, the housing has a protruding mounting part that matches the motor, and the tip double gear is disposed near the mounting part.

[0008] Preferably, the actuator further includes an output shaft that is fixedly connected to the output gear and has one end extending out of one side of the housing mounting portion, and the output gear is fixedly sleeved on the output shaft.

[0009] Preferably, the end of the output shaft that protrudes from the housing is provided with a recessed groove.

[0010] Preferably, the double gear located between the tip double gear and the output gear is the first double gear, and the double gear located between the tip double gear and the input gear is the second double gear, and the number of the second double gear is greater than the number of the first double gear.

[0011] According to the above technical solution, the compact intelligent actuator provided by this utility model has the following beneficial effects in use: Firstly, several double gears are arranged in a V-shaped stepped manner, with the pointed double gear located at the lowest or highest point of the several double gears. That is, the double gears at both ends are arranged in a stepped manner with the pointed double gear as the center, thus reducing the overall height of the several double gears. Secondly, the multiple double gears are arranged in a V-shape, which has a higher space utilization rate compared to the existing vortex distribution. This reduces the overall size of the actuator and allows it to be used in small spaces. The height and length of the actuator can be adjusted to make its shape more cubic, thus making it suitable for small space environments. This makes it highly adaptable and applicable to a wider range of environments.

[0012] Other features and advantages of this utility model will be described in detail in the following detailed description section; and all parts not covered in this utility model are the same as or can be implemented using existing technology. Attached Figure Description

[0015] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0016] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0017] like Figure 1-6 As shown, a compact intelligent actuator includes: a housing 1, an input gear 2, an output gear 3, and several double gears for connecting the output gear 3 and the input gear 2. Each double gear is fitted with a rotating shaft mounted on the housing 1. The several double gears are arranged in a V-shaped stepped manner, and the double gear located at the tip of the V-shape is a pointed double gear 4, which is located at the lowest or highest point of the several double gears.

[0018] In the above technical solution, several double gears are arranged in a V-shaped stepped manner, with the tip double gear 4 located at the lowest or highest point of the several double gears. That is, the double gears at both ends are arranged in a stepped manner with the tip double gear 4 as the center, thus reducing the overall height of the several double gears. Several double gears are arranged in a V-shape, which has a higher space utilization rate compared to the existing spiral distribution. It can reduce the overall size of the actuator and can be used in small spaces. The height and length of the actuator can be adjusted to make the shape of the actuator tend to be cube-shaped, thus making it suitable for small space environments. It has strong applicability and a wider range of applicable environments.

[0019] In a preferred embodiment of this utility model, the input gear 2 and the input gear 2 are arranged close to each other.

[0020] In the above technical solution, several double gears are arranged in a V-shape, with the input gear 2 and the output gear 3 located at the two ends of the V-shape respectively. The input gear 2 and the output gear 3 are arranged close to each other, which can reduce the overall volume of the input gear 2, the output gear 3 and several double gears without interfering with each other, thereby improving the space utilization rate inside the housing 1.

[0021] In a preferred embodiment of the present invention, the actuator further includes a motor 5, the input gear 2 is fixedly sleeved on the shaft of the motor 5, the housing 1 has a protruding mounting part 6 that matches the motor 5, and the tip double gear 4 is disposed near the mounting part 6.

[0022] In the above technical solution, the tip double gear 4 is set close to the mounting part 6, that is, the input gear 2 is set close to the center of the housing 1. The distance between the input gear 2 and the mounting part 6 is increased, providing installation space for the motor 5, thereby reducing the height of the mounting part 6 and reducing the volume of the entire actuator.

[0023] In a preferred embodiment of the present invention, the actuator further includes an output shaft 7 that is fixedly connected to the output gear 3 and has one end extending through one side of the mounting portion 6 of the housing 1, and the output gear 3 is fixedly sleeved on the output shaft 7.

[0024] In the above technical solution, the output shaft 7 and the mounting part 6 are located on opposite sides of the housing 1, which is conducive to installation. At the same time, it allows the output shaft and the PCB board to overlap in the axial direction of the output shaft 7. The PCB board is used in existing actuators to connect external signals to control the motor, thereby improving space utilization.

[0025] In a preferred embodiment of this utility model, the end of the output shaft 7 that protrudes from the housing 1 is provided with a recessed irregular groove.

[0026] In the above technical solution, the irregularly shaped slot facilitates connection with an external connecting shaft.

[0027] In a preferred embodiment of this utility model, the double gear located between the tip double gear 4 and the output gear 3 is a first double gear 8, and the double gear located between the tip double gear 4 and the input gear 2 is a second double gear 9. The number of second double gears 9 is greater than the number of first double gears 8.

[0028] In the above technical solution, because the output gear 3 is large, the specifications of the double gears that mesh sequentially from the output gear 3 to the input gear 2 decrease sequentially. Furthermore, the specifications of the first double gear 8 are also larger than those of the second double gear 9. In order to balance the overall thickness of the several double gears, the output gear 3, and the input gear 2, the number of second double gears 9 is greater than the number of first double gears 8. By reasonably controlling the number of first double gears 8 and second double gears 9, the overall thickness can be reduced, further reducing the size of the actuator.

[0029] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0030] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0031] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
