[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0020] Please see Figures 1-2 This utility model discloses a spring device with continuously adjustable spring characteristics, including a support frame 1, a servo motor 2 installed on the inner wall of the support frame 1, a controller 3 installed on one side of the support frame 1, a sleeve 4 installed on the top surface of the support frame 1, a sliding groove 5 and a limiting groove 13 opened on the inner wall of the sleeve 4, an mounting plate 6 installed on the bottom surface of the sleeve 4, a bearing 7 installed on the inner wall of the mounting plate 6, a threaded rod 8 installed on the inner wall of the bearing 7, an adjusting plate 9 installed on the outer surface of the threaded rod 8, a spring 10 installed on the top surface of the adjusting plate 9, a force plate 11 installed on the top of the spring 10, a connecting rod 12 installed on the top surface of the force plate 11, and a limiting block 14 installed on the inner wall of the limiting groove 13.
[0021] The bottom surface of the inner wall of the support frame 1 is fixedly connected to the bottom surface of the servo motor 2, and the servo motor 2 and the controller 3 are electrically connected to each other.
[0022] The bottom surface of the sleeve 4 is fixedly connected to the top surface of the support frame 1, and the inner wall of the sliding groove 5 is in sliding contact with the outer surface of the adjusting plate 9.
[0023] The servo motor 2 is started by the controller 3. As needed, the desired characteristics of the spring, such as the spring stiffness and compression, are set by the controller 3.
[0024] Servo motor drive: After receiving a control signal, servo motor 2 begins to rotate. The rotation of the servo motor drives the threaded rod 8 to rotate. The rotation of the threaded rod 8 causes the adjusting plate 9 to move along the axial direction of the threaded rod 8. The movement of the adjusting plate 9 compresses or stretches the spring 10, thereby changing the spring's compression or stiffness. Example 2
[0025] Based on the above embodiment 1, please refer to Figures 3-5 The outer surface of bearing 7 is fixedly connected to the inner wall of mounting plate 6, and the inner wall of bearing 7 is fixedly connected to the outer surface of threaded rod 8.
[0026] The inner wall of the adjusting plate 9 and the outer surface of the threaded rod 8 are rotatably connected to each other. The bottom end of the spring 10 and the top surface of the adjusting plate 9 are fixedly connected to each other. The threaded rod 8 is located on the inner wall of the spring 10. The bottom surface of the force plate 11 and the top end of the spring 10 are fixedly connected to each other.
[0027] The outer surface of the linkage rod 12 is slidably connected to the inner wall of the top end of the sleeve 4. The limiting block 14 is symmetrically installed on the outer surface of the force plate 11, and the outer surface of the limiting block 14 is slidably connected to the inner wall of the limiting groove 13.
[0028] As the adjusting plate 9 moves, the compression of the spring 10 changes, thereby altering the spring's stiffness or other properties. The force-bearing plate 11 moves with the extension and retraction of the spring 10, and the force is transmitted to the top of the sleeve 4 via the connecting rod 12. The limiting block 14 on the outer side of the force-bearing plate 11 slides within the limiting groove 13, ensuring the stable movement of the force-bearing plate 11. The sliding contact between the sliding groove 5 and the adjusting plate 9 also ensures the smoothness of the adjustment.
[0029] The working principle and usage process of this utility model are as follows: First, the servo motor 2 is started through the controller 3. As needed, the desired characteristics of the spring, such as the spring stiffness and compression, are set through the controller 3.
[0030] Servo motor drive: After receiving the control signal, servo motor 2 starts to rotate. The rotation of the servo motor drives the threaded rod 8 to rotate.
[0031] Threaded rod adjustment: Rotation of the threaded rod 8 causes the adjusting plate 9 to move axially along the threaded rod 8. The movement of the adjusting plate 9 compresses or stretches the spring 10, thereby changing the spring's compression or stiffness.
[0032] Spring characteristic adjustment: As the adjusting plate 9 moves, the compression of the spring 10 changes, which in turn changes the stiffness or other characteristics of the spring. The force plate 11 moves with the extension and retraction of the spring 10 and transmits the force to the top of the sleeve 4 through the linkage rod 12.
[0033] Limiting and stabilizing: The limiting block 14 on the outer side of the force plate 11 slides within the limiting groove 13 to ensure the stable movement of the force plate 11. The sliding contact between the sliding groove 5 and the adjusting plate 9 also ensures the smoothness of the adjustment.
[0034] Monitoring and Adjustment: Users can monitor the current state of the spring in real time through controller 3. As needed, users can fine-tune the servo motor 2 through controller 3 to further adjust the characteristics of the spring.
