Description

Technical Field

[0001] This utility model relates to the field of robotics technology, specifically to a head rotation mechanism driven by a servo motor. Background Technology

[0002] As the application scenarios of small robots continue to expand, the performance and ease of use of their head rotation mechanisms are gradually becoming key factors affecting the overall user experience. Currently, the mechanisms used to drive the head rotation of small robots often have significant design shortcomings. On the one hand, they struggle to achieve a wide range of left and right rotation, directly limiting the robot's observation or working coverage and failing to meet diverse usage needs. On the other hand, some mechanisms employ complex structural designs to achieve basic rotation effects, resulting in a large and bulky overall size. This not only disrupts the robot's overall aesthetic harmony but may also hinder its flexible movement in confined spaces.

[0003] In addition, existing head rotation mechanisms are inconvenient to disassemble and assemble. Most structures lack convenient fixing and disassembly designs, and some mechanisms that use plug-in connections cannot even achieve reliable locking. During robot operation, the head is prone to falling off, which seriously affects the stability of use and increases subsequent maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a servo motor driven head rotation mechanism, which aims to solve the problems of limited left and right rotation angles, bulky structure, and inconvenient assembly and disassembly of small robot heads.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A servo-driven head rotation mechanism includes a main body, a servo motor, a drive shaft, a first link, a second link, a connecting plate, a connecting device, and a sleeve servo motor mounted on the main body and fixedly connected to the main body. The drive shaft is mounted on the servo motor; one end of the first connecting rod is rotatably connected to the drive shaft, and the other end is rotatably connected to the second connecting rod; one end of the connecting plate is rotatably connected to the second connecting rod, and the other end is rotatably connected to the sleeve; the sleeve is located in the middle of the main body; the sleeve and the connecting device are rotatably connected.

[0006] Preferably, the connecting device is a connecting rod. Preferably, the locking device is a quick-release latch. Beneficial effects

[0007] This servo-driven head rotation mechanism, through the cooperation of the servo and the eccentric crank mechanism, effectively improves the problem of limited left and right rotation angles of the small robot's head, making head rotation smoother and more flexible. Its design of fixing the servo to the main frame, combined with the compact fit of the body connecting rods and rod sleeves, significantly optimizes the bulky structure, making the overall structure simpler and lighter.

[0008] Meanwhile, the quick-release locking tongue and the head shell slot not only enable convenient disassembly and assembly without tools, but also reliably lock the mechanism, completely solving the problem that the head is easy to fall off due to the inability to fix the plug-in position in the past, and significantly improving the ease of use and operational stability of the mechanism.

[0009] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

Detailed Implementation

[0011] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0012] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0013] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0014] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0015] like Figures 1 to 3 As shown, a servo-driven head rotation mechanism includes a main body 1, a servo motor 2, a transmission shaft 3, a first connecting rod 4, a second connecting rod 5, a connecting plate 6, a connecting device 7, a sleeve 8, and a locking device 9.

[0016] Servo motor 2 is mounted on the main body 1 and fixedly connected to it; drive shaft 3 is mounted on servo motor 2; one end of first connecting rod 4 is rotatably connected to drive shaft 3, and the other end is rotatably connected to second connecting rod 5; one end of connecting plate 6 is rotatably connected to second connecting rod 5, and the other end is rotatably connected to sleeve 8; sleeve 8 is located in the middle of the main body 1 and is detached from connecting device 7; sleeve 8 and connecting device 7 are rotatably connected. Locking device 9 is detachably connected to sleeve 8. Drive shaft 3 and connecting device 7 form an eccentric crank mechanism. The rotatable connections between the above components are all achieved through bearings or connecting rods, which are conventional technical means for those skilled in the art.

[0017] Preferably, the connecting device 7 is a connecting rod used to transmit the power output from the drive shaft 3.

[0018] Preferably, the locking device 9 is a quick-release locking tongue, which is used to cooperate with the head shell slot to achieve tool-free quick release and solve the problem that the previous plug-in position could not be locked and the head was easy to fall off.

[0019] When using Servo motor 2 is fixed on the main body 1 and is mainly used to provide the power for reciprocating swing. When in use, servo motor 2 is started first, and servo motor 2 drives the transmission shaft 3 to rotate. The transmission shaft will drive the first link 4 connected to it to move. The first link 4 then pushes or pulls the second link 5. The second link 5 transmits the power to the connecting plate 6. The connecting plate 6 then drives the sleeve 8 to move around its connection position with the main body 1. The movement of the sleeve 8 will drive the connecting device 7 to achieve the technical effect of controlling the rotation of the robot head.

[0020] Meanwhile, the eccentric crank mechanism formed by the drive shaft 3 and the connecting device 7 can effectively break through the limitations of traditional rotation angles, allowing the connecting device 7 to smoothly drive the head to achieve a wide range of smooth and flexible left and right rotations, meeting diverse observation or work needs.

[0021] In terms of structural design, the fixing method of the servo motor 2 and the main body 1, combined with the compact cooperation of the connecting device 7 and the sleeve 8, greatly simplifies the overall structure and avoids the problem of bulkiness. It not only ensures the coordination of the robot's appearance, but also does not affect its movement in narrow spaces. When it is necessary to disassemble or assemble the head, no additional tools are required. The locking device 9 can be operated directly. When disassembling, the locking device 9 can be disengaged from the slot of the head shell to remove the head. When installing, the locking device 9 can be locked into the slot of the head shell to achieve reliable locking. This fundamentally solves the problem of the head easily falling off and ensures the stable operation of the entire mechanism.

[0022] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0023] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
