Description

Technical Field

[0001] The utility model relates to a moving mechanism, in particular to a bidirectional moving mechanism. Background Art

[0002] With the continuous advancement of technology, the application of automated equipment in industrial production, robotics, smart homes and other fields is becoming increasingly widespread. These devices require flexible movement capabilities to adapt to complex working environments and diverse operational requirements. Therefore, the development and application of multi-directional motion mechanisms has become particularly important and has become a key technology to improve the functionality and efficiency of these devices.

[0003] Currently, existing multi-directional motion mechanisms typically rely on multiple drive mechanisms or the switching of transmission components to achieve multi-directional synchronous movement. Specifically, these mechanisms may use multiple motors, gears, or chain systems to drive movement in different directions. These designs help improve the controllability of multi-directional movement.

[0004] However, this complex design also brings about an increase in the number of mechanical components and challenges in coordinated control, leading to an increase in the potential risk of system failure. In particular, in some scenarios where only bidirectional movement is required and independent control of each direction is not required, the existing multi-directional movement mechanism design may not be suitable. If multiple drive sources or switching transmission mechanisms are still used, it will not only increase manufacturing and maintenance costs, but also limit the scope of application and restrict its use in a wider range of fields. Therefore, it is urgent to propose a bidirectional movement mechanism to solve the above problems. Utility Model Content

[0058] like Figures 1 to 5As shown, a preferred embodiment of the present application provides a bidirectional moving mechanism including a driving mechanism 100, a first cam assembly 200, a second cam assembly 300 and a moving seat 400. The driving mechanism 100 includes a rotating shaft 110, which rotates in a controlled manner, and the rotation axis of the rotating shaft 110 coincides with its own axis; the first cam assembly 200 includes a first cam 210, a first bracket 220 and a first follower 230, wherein the first cam 210 is fixedly sleeved on the outside of the rotating shaft 110 and rotates synchronously with the rotating shaft 110, the first cam 210 is provided with a first cam groove 211 on a side parallel to the axis of the rotating shaft 110, the first bracket 220 is restricted to move in a first direction, and the first direction is parallel to the axis of the rotating shaft 110, the first follower 230 is mounted on the first bracket 220, and the first follower 230 is movably arranged in the first cam groove 211 to drive the first bracket 220 to move; the second cam assembly 300 includes a second cam 310, a second bracket 320 and a second follower 330, wherein the second cam 310 is fixedly sleeved on the outside of the rotating shaft 110 and rotates synchronously with the rotating shaft 110, and the second cam 310 is provided with a second cam groove 311 on a side surface perpendicular to the axis of the rotating shaft 110, and the second bracket 320 is restricted to move along the second direction, and the second direction is parallel to the rotation plane of the rotating shaft 110, and the second follower 330 is arranged on the second bracket 320, and the second follower 330 is movably arranged in the second cam groove 311 to drive the second bracket 320 to move; the movable seat 400 is arranged at one end of the first bracket 220 away from the first follower 230 to move synchronously with the first bracket 220, and the end of the second bracket 320 away from the second follower 330 is slidably connected to the movable seat 400.

[0059] In this embodiment, the bidirectional movement mechanism solves the problems of complexity and high cost of multi-directional movement mechanisms by integrating the design of the drive mechanism 100 and the cam assembly. Specifically, due to the technical means of realizing bidirectional movement through the cooperation of the rotating shaft 110, the first cam groove 211 and the second cam groove 311, the use of multiple drive mechanisms 100 and complex transmission parts switching is avoided, thereby simplifying the mechanism structure, reducing the number of mechanical components and the complexity of coordinated control. Therefore, it effectively solves the problems of high manufacturing and maintenance costs and increased potential failure risks in the prior art, thereby achieving efficient and stable bidirectional movement capabilities, and improving the adaptability and application range of the equipment in different scenarios.

[0060] The rotating shaft 110 is the core component of the entire mechanism, and provides driving force through controlled rotation to ensure that the connected first cam 210 and second cam 310 can rotate synchronously.

[0061] The first cam 210 is a transmission mechanism for driving the first bracket 220 to move, converting the rotation of the shaft 110 into the movement of the first bracket 220 along the first direction. Figures 4 and 5 As shown, the design of the first cam groove 211 allows the first follower 230 to move along the groove when the first cam 210 rotates, thereby achieving linear movement of the first bracket 220, which plays a role in converting the rotation of the shaft 110 into linear motion in the overall mechanism.

[0062] The first bracket 220 is a key component of the bidirectional movement mechanism, primarily responsible for supporting and guiding the movement of the first follower 230. Specifically, the first bracket 220 can be embodied as an elongated structure, one end of which is fixedly connected to the first follower 230 and the other end is connected to the movable base 400. The first bracket 220 is designed to allow free movement in a first direction, while its structure and external constraints ensure that it does not twist or deflect during movement. The first bracket 220 can be constructed of lightweight yet durable materials, such as aluminum alloy or engineering plastic, to reduce overall weight and improve durability. The primary function of the first bracket 220 is to support and guide the first follower 230 as it slides within the first cam groove 211. When the rotating shaft 110 rotates, the first cam 210 drives the first follower 230 along the first cam groove 211, thereby causing the first bracket 220 to move in the first direction. This movement directly affects the position of the movable base 400 to which it is connected, thereby achieving the desired movement in one direction of the bidirectional movement. The first bracket 220 is designed as an elongated structure, effectively transmitting power from the first follower 230, enabling precise linear movement of the movable base 400. The kinematic characteristics of the first bracket 220, in synergy with the first cam assembly 200, provide the bidirectional motion mechanism with greater flexibility and reliability, thus meeting the needs of various automated equipment in complex working environments.

[0063] The primary function of the first follower 230 is to convert the rotational motion of the first cam 210 into linear motion of the first bracket 220. Specifically, the first follower 230 is embodied as a pulley or guide wheel, typically cylindrical. This shape allows it to slide freely within the first cam groove 211 while abutting against the inner wall of the first cam groove 211. This ensures stable movement of the first follower 230 within the first cam groove 211, preventing it from shifting during movement. The first follower 230 can be made of wear-resistant engineering plastic or metal to enhance its durability and stability during movement. The primary function of the first follower 230 is to slide under the drive of the first cam 210. When the rotating shaft 110 rotates, the first cam 210 rotates, driving the first follower 230 within the first cam groove 211. Through this motion, the first follower 230 propels the connected first bracket 220 in a first direction, thereby causing the connected movable base 400 to move synchronously. This motion conversion process is the core of the bidirectional movement mechanism. The first follower 230, working in conjunction with the first cam 210, efficiently converts rotary motion into linear motion. Its design and functionality enable the bidirectional motion mechanism to flexibly address diverse motion requirements in complex automation applications, improving overall equipment reliability and efficiency. The precise movement and wear resistance of the first follower 230 ensure system stability over extended periods of operation, meeting high performance requirements.

[0064] In some embodiments, the first cam assembly 200 also includes a first linear guide pair and a first support 240, wherein the first linear guide pair includes a first linear guide 250 and a first slider 260, the extension direction of the first linear guide 250 is parallel to the axis of the rotating shaft 110, the first slider 260 is slidingly connected to the first linear guide 250, the first support 240 is fixedly connected to the first slider 260 so as to move synchronously with the first slider 260, and a first guide groove is provided on the first support 240 for the first bracket 220 to pass through and slide with it to limit the moving direction of the first bracket 220 to the first direction, and the shape and size of the first guide groove are adapted to the shape and size of the cross-sectional profile of the first bracket 220.

[0065] The second cam 310 is a transmission mechanism for driving the second bracket 320 to move, converting the rotation of the rotating shaft 110 into the movement of the second bracket 320 along the second direction. Figures 4 and 5 As shown, the annular guide groove formed on the end surface allows the second follower 330 to slide therein. This design ensures that when the second cam 310 rotates with the rotating shaft 110, the second follower 330 moves within the second cam groove 311, thereby driving the second bracket 320 to move in the second direction, effectively converting the rotation of the rotating shaft 110 into linear movement in another direction.

[0066] The second bracket 320 is a crucial component of the bidirectional motion mechanism, primarily used to support and guide the movement of the second follower 330 and convert its linear displacement into overall motion of the mechanism. Specifically, the second bracket 320 can be embodied as a long rod, designed to provide a certain degree of strength and rigidity. One end of the second bracket 320 is connected to the second follower 330, and the other end is slidably connected to the movable base 400, ensuring stability during motion. Aluminum alloy or other lightweight, high-strength materials can be used to reduce overall weight and increase tensile strength. The primary function of the second bracket 320 is to support the movement of the second follower 330 and effectively transmit its displacement to the movable base 400. When the second cam 310 rotates, the second follower 330 slides within the second cam groove 311, pushing the second bracket 320 in the second direction. This design enables coordinated movement of the second bracket 320 with the first bracket 220, thereby enhancing the flexibility of the bidirectional motion mechanism. The design and functionality of the second bracket 320 enable the bidirectional motion mechanism to achieve smooth and efficient multi-directional motion. Its coordination with the second follower 330 ensures accurate and continuous motion, providing the necessary support and guidance for the entire system. Through its optimized structural design, the second bracket 320 not only improves the durability of the mechanism but also effectively reduces frictional losses during motion, enhancing the reliability of the bidirectional motion mechanism in automation and industrial applications.

[0067] The second follower 330 is responsible for converting the rotational motion of the second cam 310 into linear motion of the second bracket 320. Specifically, the second follower 330 is embodied as a pulley or guide wheel, typically cylindrical in shape. Its dimensions are adapted to the second cam groove 311 to ensure smooth coordination with the second cam 310 during movement. High-strength plastic or metal is often used for enhanced wear resistance and pressure resistance. The primary function of the second follower 330 is to convert the rotational motion of the second cam 310 into linear motion in the second direction. As the second cam 310 rotates, the second follower 330 slides within its groove, pushing the second bracket 320 to move, thereby cooperating with the first cam assembly 200 to achieve the function of the entire bidirectional motion mechanism. Due to its rational structural design, the second follower 330 efficiently and accurately transmits power to the second bracket 320. The design and function of the second follower 330 are central to the smooth operation of the bidirectional motion mechanism. Its coordination with the second cam 310 enables efficient and stable bidirectional motion.

[0068] The second cam assembly 300 also includes a second support 340, a guide member 350 and a sliding member 360, wherein the second support 340 is provided with a second guide groove for the second bracket 320 to pass through and slide with it to limit the moving direction of the second bracket 320 to the second direction, the guide member 350 is arranged on the side of the moving seat 400 facing the second cam 310, and the guide member 350 is provided with a linear guide groove 351 along the first direction, the sliding member 360 is fixedly connected to the end of the second bracket 320 away from the second follower 330, and the sliding member 360 is arranged in the linear guide groove 351 in a sliding connection manner, so that the second bracket 320 can move along the second direction while the moving seat 400 moves along the first direction.

[0069] The movable base 400 has at least one plane, which is located on the side of the movable base 400 away from the rotating shaft 110 for mounting external equipment. The movable base 400 is embodied as a plate in a specific manner. For example, Figures 1 to 2 As shown, one end of the first bracket 220 is fixedly connected to one end of the plate, and the end of the second bracket 320 facing away from the second follower 330 is slidably connected to the side of the plate toward the rotating shaft 110, thereby ensuring that the entire mechanism can achieve bidirectional movement.

[0070] The movable base 400 is responsible for carrying external devices and connecting the first bracket 220 and the second bracket 320 to achieve multi-directional movement. Specifically, the movable base 400 can be embodied as a flat plate. The side of the first bracket 220 facing away from the first follower 230 is fixedly connected to the movable base 400, while the other side of the movable base 400 is slidably connected to the end of the second bracket 320 facing away from the second follower 330. This structural design allows the movable base 400 to move flexibly in response to the movement of the first bracket 220 and the second bracket 320. The primary function of the movable base 400 is to convert the movement of the first bracket 220 and the second bracket 320 into overall movement. Through its connection with the first bracket 220 and the second bracket 320, the movable base 400 can move synchronously in the first and second directions, thereby achieving overall bidirectional movement. This design ensures the efficiency and stability of the mechanism. As a key component connecting the first bracket 220 and the second bracket 320, the movable base 400 plays a key role in load bearing and transmission in the entire bidirectional movement mechanism. Its stability and flexibility directly affect the overall performance of the mechanism, ensuring efficient and reliable movement in different working scenarios. Therefore, the design and function of the moving base 400 not only enhances the operational flexibility of the bidirectional moving mechanism, but also improves its applicability in practical applications.

[0071] In some embodiments, there is only one first cam 210, and the axis of the first cam 210 is collinear with the axis of the rotating shaft 110. There are two second cams 310, one at each end of the first cam 210, and the axes of the two second cams 310 are collinear with the axis of the rotating shaft 110.

[0072] like Figures 6 to 8 As shown, the first cam groove 211 is composed of a first stationary groove section 2111 and a first driving groove section 2112. When the first follower 230 moves through the first stationary groove section 2111, the first bracket 220 remains stationary. When the first follower 230 moves through the first driving groove section 2112, the first follower 230 moves along the first direction. The second cam groove 311 includes a second stationary groove section 3111 and a second driving groove section 3112. When the second follower 330 moves through the second stationary groove section 3111, the second bracket 320 remains stationary. When the first follower 230 moves through the second driving groove section 3112, the second follower 330 moves along the second direction.

[0073] In some embodiments, the graphical area formed by the line connecting the orthographic projection of the first drive slot segment 2112 on the rotation plane of the rotating shaft 110 and the axis of the rotating shaft 110 is defined as the first drive area, and the graphical area formed by the line connecting the orthographic projection of the second drive slot segment 3112 on the rotation plane of the rotating shaft 110 and the axis of the rotating shaft 110 is defined as the second drive area. The first drive area and the second drive area are arranged so as not to overlap, so that the movable base 400 can only move in the first direction or the second direction at any one time. In other words, the first bracket 220 and the second bracket 320 do not move simultaneously; at any one time, only the first bracket 220 or the second bracket 320 moves in the corresponding direction.

[0074] In other embodiments, the graphical area formed by the line connecting the orthographic projection of the first driving slot segment 2112 on the rotation plane of the rotating shaft 110 and the axis of the rotating shaft 110 is defined as the first driving area, and the graphical area formed by the line connecting the orthographic projection of the second driving slot segment 3112 on the rotation plane of the rotating shaft 110 and the axis of the rotating shaft 110 is defined as the second driving area. The first driving area and the second driving area are arranged to overlap, so that the movable base 400 can move simultaneously in the first direction and the second direction. In other words, the first bracket 220 and the second bracket 320 will move simultaneously in the first direction and the second direction at the same time.

[0075] In some embodiments, a bidirectional movement mechanism further includes a base plate 500, a support plate 600, a pillar 700, and a second linear guide pair 800, wherein the base plate 500 includes a first mounting plane, the first direction is parallel to the first mounting plane, and the second direction is perpendicular to the first mounting plane. The support plate 600 includes a second mounting plane, the second mounting plane is arranged parallel to the first mounting plane, and the support plate 600 is located between the base plate 500 and the movable seat 400, and the support plate 600 is provided with a through slot 610 for the first bracket 220 and the second bracket 320 to pass through. One end of the pillar 700 is fixedly connected to the base plate 500, and the other end of the pillar 700 is fixedly connected to the support plate 600. The second linear guide pair 800 includes a second linear guide 810, which is arranged on the second mounting plane, and the extension direction of the second linear guide 810 is parallel to the axis of the rotating shaft 110. The second slider 820 is arranged on the movable seat 400, and the second slider 820 is slidably connected to the second linear guide 810.

[0076] In some embodiments, the drive mechanism 100 further includes a shaft seat 120, a driver 130, and a transmission assembly (not shown). The shaft seat 120 and the driver 130 are both mounted on a first mounting plane. A bearing is provided on the shaft seat 120, and the rotating shaft 110 is rotatably connected to the shaft seat 120 via the bearing. The driver 130 includes an output end that rotates in a controlled manner, and the output end of the driver 130 is transmission-connected to the rotating shaft 110 via the transmission assembly.
