Description

Technical Field

[0001] The utility model relates to the technical field of steering gears, in particular to a bus steering gear with multiple interfaces. Background Art

[0002] Currently, high-precision equipment is required in the industrial field, and the servo is a position servo drive suitable for applications that require precise angle control. It can accurately control the rotation angle through the internal position feedback system. Especially in the field of robotics, the servo is set on each rotating joint component of the robot to control the rotation angle of the joint component or the tension and closing degree of grasping objects. Therefore, the cooperation of multiple servos is required to achieve high-precision robot movement, but setting up multiple servos also creates the problem of complex line connection.

[0003] A general servo has only one input interface. In actual application scenarios, each servo needs to be connected to a power signal line separately to control the operation of the servo. When multiple servos need to work together, the servos cannot be directly connected in series. They need to be connected separately to the same control source. In a limited space, the difficulty and complexity of wiring are increased, resulting in an extremely chaotic and cumbersome layout of the overall circuit. Therefore, a more reasonable servo structure is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0004] Aiming at the disadvantage that the servo has only a single connector in the above technology, which makes wiring difficult and complicated, the utility model provides a bus servo with multiple interfaces.

[0005] To achieve the above-mentioned purpose, the present invention provides a bus servo with multiple interfaces, comprising an upper shell, a connecting shell and a lower shell connected in sequence, wherein the upper shell, the connecting shell and the lower shell are connected to form a accommodating cavity, and a first main control board, a second main control board and a drive motor electrically connected to the first main control board and the second main control board are provided in the lower shell, a drive gear set is provided in the upper shell, and the output end of the drive motor is connected to the drive gear set; at least two connectors electrically connected to the first main control board and the second main control board are provided in the lower shell, and one end of the connector protrudes out of the lower shell.

[0006] As an improved solution of the present invention, the end surface of the connector extending out of the lower shell is flush with the outer wall surface of the lower shell.

[0007] As an improved solution of the present invention, a first mounting slot adapted to the connector is provided on the wall surface of the lower shell, the number of the first mounting slots is adapted to the connector, and one connector is correspondingly arranged on one first mounting slot.

[0008] As an improved solution of the present invention, a second mounting slot adapted to the connector is formed on the connecting surface of the connecting shell and the lower shell; when the lower shell and the connecting shell are assembled, the first mounting slot and the second mounting slot fit together to clamp the connector.

[0009] As an improved solution of the present invention, the second main control board is fixedly arranged on the lower shell, the connector is arranged between the first main control board and the second main control board, and the first main control board and the second main control board are attached to the connector.

[0010] As an improved solution of the present invention, a surface of the second main control board close to the connecting shell is flush with the bottom surface of the first installation notch.

[0011] The beneficial effects of the present invention are as follows: compared with the prior art, the present invention provides a bus servo with multiple interfaces. The servo of the present application has multiple connectors, so that the servos can be connected in series with each other. Only one servo needs to be connected to the control source to control the other servos to work together, which reduces the lines connecting the servos and the control source, improves the neatness of the overall line layout, and solves the problem of chaotic and complicated line layout caused by the inability to connect servos; and the servo can also be connected to other electronic components through connectors, thereby enhancing the closed-loop control of the servo and improving the scalability of the servo.

[0019] In order to more clearly illustrate the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0020] In the following description, examples are provided to provide a deeper understanding of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. It should be understood that the specific embodiments described are only for the purpose of explaining the present invention and are not intended to limit the present invention.

[0021] It should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the stated features, integers, steps, operations, elements or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components or combinations thereof.

[0022] At present, since most of the servos in the existing technology only have a single interface, that is, the servos cannot be directly connected in series, and need to be connected to the same control source, the arrangement of the connecting wires is difficult and complicated, making the line distribution disorganized and difficult to organize. Therefore, a more reasonable servo structure is urgently needed to solve the above-mentioned technical problems.

[0023] See also Figures 1-4 In order to solve the above-mentioned technical problems, the present invention provides a bus servo with multiple interfaces, including an upper housing 1, a connecting housing 3 and a lower housing 2 connected in sequence. The lower housing 2 is provided with a drive motor 4, a main control board 5 and at least two connectors 6 electrically connected to the first main control board 5 and the second main control board 8. The upper housing 1 is provided with a drive gear set 7, and the output end of the drive motor 4 is connected to the drive gear set 7. The lower housing is provided with at least two connectors 6 electrically connected to the first main control board 5 and the second main control board 8. One end of the connector 6 protrudes from the outside of the lower housing, and the connector 6 protrudes from the lower housing 2. The end face of the outer end is flush with the outer wall of the lower shell 2, and a first mounting slot 9 adapted to the connector 6 is provided on the wall of the lower shell 2. The number of the first mounting slots 9 is the same as the number of the connectors 6, and one connector 6 is correspondingly arranged on one first mounting slot 9; in order to reduce the difficulty of circuit layout, a plurality of connectors 6 are arranged inside the lower shell 2 and electrically connected to the first main control board 5 and the second main control board 8, so that the control output of the servo can be more flexible and controllable, and the servos can be connected in series with each other, thereby reducing the line connection path between the servo and the control source and improving the simplicity of the overall circuit.

[0024] See also Figure 1 and Figure 3In actual application scenarios, depending on the structural size of the servo, the number of connectors 6 can be configured to be three, respectively arranged on the two opposite sides of the lower shell 2 and the end face of the lower shell 2. It can be understood that the connector 6 can also be arranged at the bottom position of the lower shell 2, and depending on the size of the servo, a servo with a larger internal space can also be provided with multiple connectors 6 on the same side; furthermore, multiple connectors 6 can also enable the servo to be connected to other electronic products, such as encoders, force sensors, etc., to enhance the closed-loop control and expandability of the servo.

[0025] In another embodiment, all technical features of the above embodiment are included. Figure 3-Figure 4 In order to achieve stable assembly of the connector 6, the second main control board 8 is fixedly arranged on the inner bottom surface of the lower shell 2, and the connector 6 is arranged between the second main control board 8 and the first main control board 5. The connector 6 fits with the second main control board 8 and the first main control board 5. Since the connector 6 is arranged on the second main control board 8, the connector 6 fits with the first control board 5, which ensures that the connector 6 is tightly and stably arranged inside the shell.

[0026] In this example, see Figure 1 、 Figure 3 and Figure 5 A second mounting notch 10 adapted to the plug connector 6 is formed on the connecting surface of the connecting shell 3 and the lower shell 2. When the lower shell 2 and the connecting shell 3 are assembled, the first mounting notch 9 and the second mounting notch 10 clamp the plug connector 6, further ensuring that the assembly of the plug connector 6 is stable, and the side of the second main control board 8 close to the connecting shell 3 is flush with the bottom surface of the first mounting notch 9, ensuring that the plug connector 6 remains flush in the horizontal direction, preventing the plug connector 6 from being installed at an angle, and avoiding the problem of the plug connector being unable to be inserted into the plug connector 6 in actual application scenarios.

[0027] The advantages of this utility model are:

[0028] 1) The servo is equipped with multiple connectors, which reduces the wiring connecting the servo and the control source, improves the neatness of the overall wiring layout, and solves the problem of confusing and complicated wiring layout caused by the inability to connect servos.

[0029] 2) The servo can also be connected to other electronic components through connectors to enhance the closed-loop control of the servo and improve the scalability of the servo.

[0030] The above disclosures are only a few specific embodiments of the present invention, but the present invention is not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
