Detailed Implementation

[0019] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention. Example

[0020] Please see Figures 1-5 As shown, this utility model provides a multi-integrated actuator, including a lower actuator housing 1, an upper actuator housing 3 detachably and sealingly connected to the upper opening of the lower actuator housing 1, a circuit board 4 installed in the mounting cavity 2, and at least two sets of actuator mechanisms are also provided in the mounting cavity 2. The actuator mechanism includes a drive motor 5 electrically connected to the circuit board 4, a worm gear 6 located on the output shaft of the drive motor 5, and a gear system 7 linked with the worm gear 6. The gear system 7 has an output gear 8 that passes through the upper actuator housing 3 to output the actuator action outward.

[0021] In this embodiment, by integrating at least two sets of actuators within the actuator housing, the actuator structural layout and circuit board connection layout are adaptively optimized and adjusted, thereby improving the flexibility and adaptability of the actuator and allowing multiple actions to be executed concurrently at the same time without interfering with each other.

[0022] like Figure 3 and 4As shown, in order to integrate the external wiring of each actuator inside the actuator, the wiring terminals are designed as a single integrated unit. In this embodiment, a multi-in-one wiring pin box 9 is provided in the middle of the outer side wall of the lower shell 1 of the actuator. Multiple pins corresponding to the circuit board 4 are fixed inside the multi-in-one wiring pin box 9. These pins include at least a power pin and a ground pin located in the center, as well as the positive terminal pin, negative terminal pin and signal feedback pin of each actuator located on the outside.

[0023] like Figure 4 As shown, to improve the installation stability of the circuit board 4, the lower housing 1 of the actuator is also provided with circuit board fixing protrusions 10 for fixing the circuit board 4, and a grid-like reinforcing rib 11 with horizontal, vertical and horizontal intersections. The circuit board fixing protrusions 10 are vertically arranged on the ribs of the grid-like reinforcing rib 11. The grid-like reinforcing rib 11 can strengthen the structural strength of the lower housing 1 of the actuator itself, and also enhance the strength of the circuit board fixing protrusions 10, making the protrusions less likely to break during the snap-fit ​​installation process.

[0024] like Figure 3 , 4 As shown in this application, the gear system 7 specifically includes a first transmission gear 12 rotatably mounted on the lower housing 1 of the actuator and meshing with the worm gear 6, and a second transmission gear 13 meshing with the first transmission gear 12 and the output gear 8 respectively. The inner side of the outer end of the output gear 8 has an output tooth 81 for connecting to an external controlled component. The output gear 8 is driven to obtain a set rotation speed through multi-stage transmission gear reduction, so as to smoothly perform the action output.

[0025] To ensure the installation stability of each drive motor 5 inside the housing, such as Figure 4 As shown, at least two sets of motor brackets 14 and at least two sets of motor limiting frames 15 are provided on the inner wall of the lower housing 1 of the actuator. The drive motor 5 is installed on the corresponding motor bracket 14 and is located between the corresponding motor limiting frame 15 and the side wall of the lower housing 1 of the actuator. There are two motor brackets 14 that are spaced apart from each other and are located at the beginning and end of the drive motor 5, respectively, for forming a stable clamping and fixing of the drive motor 5. The motor limiting frame 15 is located on the side of the drive motor installation position for lateral limiting of the drive motor 5.

[0026] like Figure 2As shown in this application, in order to improve the overall structural strength of the actuator housing 1, while also taking into account the reserved installation positions of the motor and specific gears on the housing, a portion of the lower housing 1 of the actuator protrudes outward to form a motor mounting housing 16 and an output gear mounting housing 17. The motor mounting housing 16 and the output gear mounting housing 17 are integrally formed and connected to accommodate the drive motor 5 and the output gear 8 in the same actuator group. The corner of the lower housing 1 of the actuator is also provided with several corner fixing seats 19 with fixing holes 18. The corner fixing seats 19 are integrally formed and connected to the nearby reinforcing rib motor mounting housing or output gear mounting housing. The integral forming design has high processing and manufacturing efficiency and optimizes the structural strength of the corresponding parts of the housing.

[0027] As one of the optimized designs, in this application, since multiple sets of drive mechanisms are designed to jointly control and execute actions, it is necessary to ensure the long-term stable operation of each drive motor. However, the motor may fail or be damaged due to the increased temperature after long-term operation. Therefore, the actuator also includes a temperature sensor installed in the lower housing 1 of the actuator. The temperature sensor is arranged close to the drive motor to sense the surrounding temperature of the drive motor during operation. When the temperature of the motor reaches the set threshold, the temperature parameter is fed back to the upper main control unit to issue an alarm or control the actuator to stop.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
