Description

Technical Field

[0001] This utility model belongs to the technical field of automotive automation equipment, and in particular relates to an automatic locking-unlocking motion mechanism. Background Technology

[0002] Currently, many multi-functional vehicles are designed with devices that require automatic movement. Typically, automated moving devices can only move while fixed to a single bracket or rail. If the device needs to move between two or more brackets or rails, it becomes impossible to maintain relative stability during movement. When the device moves from one bracket or rail to another, it cannot automatically disengage from the fixed connection, and the receiving bracket or rail cannot automatically lock the device in place, nor can it reliably move the device to the designated position. Especially during vehicle operation, the vibrations caused by the vehicle's movement affect the device's movement, making such movements impossible. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an automatic locking-unlocking motion mechanism that can realize the automatic transfer of equipment between any two or more supports or guide rails.

[0004] To solve the above technical problems, this utility model provides an automatic locking-unlocking motion mechanism, including a transport system and an automated manipulator. The transport system consists of a power unit, a transmission unit, and a slide rail. The automated manipulator includes a fixed claw, a movable claw, a roller, and a guide plate. The fixed claw is positioned above the slide rail and can slide along the slide rail. The power unit is connected to the fixed claw through the transmission unit. The movable claw is movably connected to the fixed claw. The lower end of the movable claw is connected to the roller. The roller is positioned above the guide plate and can roll along the guide plate.

[0005] This invention's automatic locking-unlocking motion mechanism enables automated movement of on-board equipment. It can switch between a locked, fixed state and an unlocked, freely moving state, allowing for the fixing and unlocking of fixed components. This enables the fixed components to drive the on-board equipment to move automatically between any two or more supports or guide rails. The fixed components can be connected to the equipment that needs to be moved.

[0006] The optimized technical solution of this utility model is as follows: Furthermore, the two sides of the fixed claw are respectively connected to the torsion spring and the movable claw via a rotating shaft. One end of the torsion spring is inserted into the fixing hole on the fixed claw, and the other end is stuck on the movable claw.

[0007] Furthermore, the lower end of the movable claw is connected to the roller via a roller shaft.

[0008] Furthermore, at least one end of the guide plate has a bevel.

[0009] Furthermore, the slide rail is mounted on the base plate, and a guide plate is respectively provided on both sides of the slide rail on the base plate.

[0010] Furthermore, the length of the guide plate is less than the length of the base plate.

[0011] In the above structure, the fixed claw and the movable claw are connected by a torsion spring, ensuring that the movable claw is always inclined to the open state. The lower end of the movable claw is connected to the roller via a roller shaft, and due to the action of the torsion spring, the roller is always pressed against the next plane. That is, in the locked state, the roller presses against the guide plate. When unlocking, the roller rolls along the inclined surface of the guide plate to the bottom plate, causing the lower end of the movable claw to descend without being pressed by the guide plate, so that the movable claw opens under the action of the torsion spring, releasing the fixed component. After gripping the fixed component, the roller rolls along the inclined surface of the guide plate to the guide plate. During this process, the lower end of the movable claw rises and is gradually pressed by the guide plate, eventually causing the movable claw to close, achieving the locking and fixing of the fixed component. Thus, when the roller is pressed against the guide plate, the robot is in the locked state, and vice versa, it is in the unlocked state.

[0012] Furthermore, one side of the fixing claw is provided with a groove that can match the fixing member.

[0013] Furthermore, the fastener is cylindrical.

[0014] The aforementioned fastener adopts a cylindrical structure, which facilitates the robotic arm to grasp and release the fastener.

[0015] The advantages of this utility model are its simple structure and ease of use on vehicles. It uses an automated robotic arm to grasp, fix, and unlock the equipment, and the grasping, fixing, and unlocking components are very safe and reliable, which can improve the smoothness and reliability of the transport and transfer of items between different guide rails or supports during vehicle operation.

[0021] This embodiment provides an automatic locking-unlocking motion mechanism, the structure of which is as follows: Figures 1 to 4 As shown, the system includes a base plate 2 and a slide rail 4 mounted on the base plate 2. A baffle is installed at the front and rear ends of the base plate 2. A guide plate 3 is installed on the base plate 2 on both sides of the slide rail 4. The length of the guide plate 3 is less than the length of the base plate 2, and at least one end of the guide plate 3 has a slope. A fixing claw 8 is positioned above the slide rail 4 and can slide along the slide rail 4. Specifically, a slider 13 is provided on the slide rail 4, and the fixing claw 8 is mounted on the slider 13 and can move along the slide rail 4 together with the slider 13. A groove matching the fixing member 1 is formed on the rear side of the fixing claw 8. The left and right sides of the fixing claw 8 are hinged to a movable claw 9 via a rotating shaft 12. The lower end of the movable claw 9 is connected to a roller 10 via a roller shaft 11. The roller 10 is positioned above the guide plate 3 and can roll along the guide plate 3. The fixed claw 8 and the movable claw 9 cooperate to form a robotic arm for automatically gripping or releasing the fixed component 1. The movable claw 9 swings around the rotary shaft 12. The fixed component 1 is cylindrical and is detachably connected to the vehicle-mounted mobile device. Both the fixed claw 8 and the movable claw 9 are connected to the torsion spring 5 via the rotary shaft 12. The central hole of the torsion spring 5 passes through the rotary shaft 12. One end of the torsion spring 5 is inserted into the fixed hole on the fixed claw 8, and the other end is locked onto the movable claw 9 to ensure that the movable claw 9 always tends to approach the limit position of the fixed claw 8 and tends to be in the open state.

[0022] The fixed claw 8 is connected to the transport system, which consists of a power unit 6, a transmission mechanism 7, and a slide rail 4. The length of the transport system can be set as needed, meaning the lengths of the slide rail 4 and the transmission mechanism 7 can be determined. The fixed claw 8 is fixedly connected to the power unit 6 via the transmission mechanism 7, allowing it to move along the slide rail 4 under power. The transmission mechanism 7 can be a lead screw or a hydraulic cylinder, and the power unit 6 can be a reducer or a hydraulic pump station. Specifically, the transmission mechanism 7 converts the output of the power unit 6 into linear displacement of the fixed claw 8, causing it to move along the slide rail 4. When the transmission mechanism 7 uses a lead screw mechanism, the power unit 6 uses a reducer. The output of the reducer drives the threaded rod of the lead screw mechanism to rotate, which in turn drives the nut fitted on the threaded rod to move linearly. The fixed claw 8 is connected to the nut and can move linearly along with it.

[0023] The movable claw 9 consists of an upper movable claw and a lower movable claw. The lower end of the upper movable claw and the upper end of the lower movable claw are hinged together by a rotary shaft 12, and the lower end of the lower movable claw is movably connected to the roller 10 by a roller shaft 11. The roller 10 is mounted on the guide plate 3 and can move along the guide plate 3.

[0024] The robotic arm of this invention has an unlocking function (see...). Figure 3 ) and locking (see Figure 2 In two states, after the robotic arm unlocks, the fixing part 1 can automatically move to the position of the robotic arm to realize the robotic arm's grasping and releasing of the fixing part 1 (see...). Figure 4 The grasping, releasing, unlocking, and locking movements are all achieved by an automated robotic arm. The automated robotic arm consists of a fixed gripper 8, a movable gripper 9, rollers 10, a torsion spring 5, a guide plate 3, roller shafts 11, and a rotary shaft 12. The automated robotic arm is used to automatically grasp and transport the fixed component 1. The transport system, as a transmission mechanism, acts as a transport mechanism after the automated robotic arm grasps the fixed component 1.

[0025] A slide rail 4 is mounted on the base plate 2, and the slider on it is used to fix the automated robot arm and provide the running trajectory for the robot arm's transport. Parallel to the slide rail 4 and mounted on the base plate 2 is a transmission mechanism 7, which provides power to the transport system. A power unit 6 is mounted at one end of the transmission mechanism 7 to provide power to the transport system. A guide plate 3 is fixed parallel to the slide rail 4 to ensure the automated robot arm can perform grasping and releasing movements (see...). Figure 2 ).

[0026] In actual use, when the robotic arm is in the unlocked position, the cylindrical fixing part 1 can roll into or out of the groove of the fixing claw 8, realizing the robotic arm's grasping and releasing of the fixing part 1. After the robotic arm grasps the fixing part 1, the power unit 6 drives the robotic arm to move forward along the guide plate 3 through the transmission mechanism 7. In the initial stage of movement, the roller 10 moves upward along the slope of the guide plate 3, driving the position of the movable claw 9 to rise, causing the movable claw 9 to close towards the fixing claw 8 to clamp the fixing part 1; when the roller 10 climbs to the top of the slope, the robotic arm is in the locked state. When it is necessary to release the fixing part 1, the power unit 6 drives the robotic arm to move backward along the guide plate 3 through the transmission mechanism 7. When the roller 10 moves to the slope position of the guide plate 3, it rolls down the slope, which will bring the position of the movable claw 9 down, causing the movable claw 9 to be released from the pressure of the guide plate 3 and gradually open under the action of the torsion spring 5, so that the robotic arm is in the unlocked state to release the fixing part 1.

[0027] The mechanism of this invention can be used in conjunction with a sensor.

[0028] In addition to the embodiments described above, this utility model may have other implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
