[0034] Example 1

[0035] This embodiment provides a bouncing device with an adjustable energy storage range, such as Figure 1 As shown, it includes a support 1, a power column 7 is arranged above the support 1, a first elastic member 2 is arranged between the power column 7 and the support 1, one end of the first elastic member 2 is connected to the support 1, and the other end is connected to the power column 7, and also includes a second elastic member 3 and a clamping structure 4.

[0036] The second elastic member 3 is arranged on the support 1, and the lower end of the second elastic member 3 is connected to the support 1. The clamping structure 4 is arranged between the power column 7 and the second elastic member 3, and is used to realize the connection or disconnection between the second elastic member 3 and the power column 7.

[0037] When the second elastic member 3 is connected to the power column 7, the power column 7 is moved, and the first elastic member 2 and the second elastic member 3 store energy together.

[0038] When the second elastic member 3 and the power column 7 are disconnected, the power column 7 is moved, and the first elastic member 2 stores energy alone.

[0039] In this embodiment, the clamping structure 4 includes a first limiting plate 401 and a second limiting plate 402. The first limiting plate 401 is fixedly connected to the power column 7, and the second limiting plate 402 is rotatably connected to the upper end of the second elastic member 3. At least one limiting ear plate 403 is fixed to the outer peripheral surface of the first limiting plate 401, and the second limiting plate 402 is provided with a through groove 405 through which the first limiting plate 401 and the limiting ear plate 403 can pass.

[0040] The connection or disconnection between the first limiting plate 401 and the second limiting plate 402 is achieved by rotating the second limiting plate 402 , thereby achieving the connection or disconnection between the second elastic member 3 and the power column 7 .

[0041] When in use, the second limiting plate 402 can be rotated to a first angle and a second angle. When the second limiting plate 402 is rotated to the first angle, the first limiting plate 401 and the limiting ear plate 403 can pass through the through slot 405; when the second limiting plate 402 is rotated to the second angle, the angle of the through slot 405 is staggered with the limiting ear plate 403, and the second limiting plate 402 blocks the limiting ear plate 403 on the side away from the second elastic member 3.

[0042] When in motion, the moving direction of the power column 7 is the same as the compression or extension direction of the first elastic member 2 and the second elastic member 3 , and both directions are vertical directions.

[0043] In order to prevent the second limit plate 402 and the first limit plate 401 from rotating off relative to each other during the subsequent movement after the second limit plate 402 is rotated to a set angle, a limit groove 406 is provided on the top of the second limit plate 402, and a ridge 404 is provided on the bottom of the limit ear plate 403. The ridge 404 matches the shape of the limit groove 406, and the cross-section of the limit groove 406 is arranged to be arc-shaped. When the second limit plate 402 is rotated to the second angle, the ridge 404 is stuck in the limit groove 406.

[0044] After the convex ridge 404 is stuck in the limiting groove 406 , under the elastic force of the second elastic member 3 , the convex ridge 404 is tightly fitted in the limiting groove 406 , so that the second limiting plate 402 and the first limiting plate 401 are tightly fitted.

[0045] In this embodiment, two limiting lug plates 403 or four limiting lug plates 403 are evenly arranged on the outer circumference of the first limiting plate 401. When two limiting lug plates 403 are arranged, the first angle is 0°, and the value range of the second angle is 30° to 150°. When four limiting lug plates 403 are arranged, the first angle is 0°, and the value range of the second angle is 30° to 60°.

[0046] In this embodiment, the first elastic member 2 is a small spring, the second elastic member 3 is a large spring, and the small spring is arranged inside the large spring.

[0047] The usage and working principle of this embodiment

[0048] During use, according to actual needs, the angle of the second limit plate 402 is manually rotated. When the second limit plate 402 is rotated to the first angle, the power column 7 moves downward, driving the first limit plate 401 and the limit ear plate 403 to move downward synchronously. The first limit plate 401 and the limit ear plate 403 pass through the through slot 405 when moving up and down, and have no connection with the second limit plate 402. Therefore, at this time, the power of the power column 7 is only transmitted to the first elastic member 2. The first elastic member 2 is compressed to absorb and store the power of the power column 7. Then, the elastic force of the first elastic member 2 bounces the power column 7 up to achieve bouncing.

[0049] When the second limit plate 402 is rotated to the second angle, the power column 7 moves up and down, driving the first limit plate 401 and the limit ear plate 403 to move downward synchronously. Due to the obstruction of the second limit plate 402, the limit ear plate 403 drives the second limit plate 402 downward at the same time. At this time, the second limit plate 402 moves downward to compress the second elastic member 3, and the first elastic member 2 and the second elastic member 3 are compressed at the same time to store energy. After the power column 7 is released, the first elastic member 2 and the second elastic member 3 release their elastic force at the same time, and the first elastic member 2 pushes the first limit plate 401 and the power column 7 to bounce upward. The second elastic member 3 drives the limit ear plate 403 through the second limit plate 402, drives the first limit plate 402 through the limit ear plate 403, and drives the power column 7 to bounce upward through the first limit plate 401, thereby realizing the common energy storage of the first elastic member 2 and the second elastic member 3, and expanding the energy storage range.

[0050] Example 2

[0051] On the basis of Example 1, the bouncing device provided in this embodiment has a cylinder 5 fixedly arranged on the support 1 in order to limit the moving direction of the second limiting plate 402 and the first limiting plate 401. The inner wall shape of the cylinder 5 matches the outer peripheral shape of the second limiting plate 402. The second limiting plate 402 is slidably arranged in the cylinder 5. A limiting structure 8 is arranged between the cylinder 5 and the first limiting plate 401. The limiting structure 8 is used to limit the movement of the first limiting plate 401 in the vertical direction.

[0052] When rotating the second limiting plate 402 , the staff pushes the second limiting plate 402 downward from the top opening of the cylinder 5 to separate the second limiting plate 402 from the first limiting plate 401 and then rotates the second limiting plate 402 .

[0053] When the second limiting plate 402 is rotated to the 0° position, the second limiting plate 402 moves upward to the top position of the cylinder 5 under the elastic force of the second elastic member 3 , and at this time the second limiting plate 402 does not affect the up and down movement of the first limiting plate 401 .

[0054] In order to enable the power column 7 to move up and down, a transmission assembly 6 is provided on the support 1, and the transmission assembly 6 is used to transmit the rotating power to the power column 7, so that the power column 7 moves up and down. The transmission assembly 6 includes a support frame 602, a rotating wheel 601, a sleeve 603, a protrusion 604 and a limit plate 605. The support frame 602 is fixed on the support 1, and the rotating wheel 601 is rotatably arranged on the support frame 602. The bottom of the rotating wheel 601 is fixedly connected to the sleeve 603. The center of the rotating wheel 601 has a through hole, and the power column 7 passes through the sleeve 603 and the through hole. The outer peripheral surface of the sleeve 603 is fixedly connected to the protrusion 604. The limit plate 605 is arranged on the outside of the sleeve 603, and the limit plate 605 is fixedly connected to the first limit plate 401. One side of the limit plate 605 is arranged as an inclined surface, and the inclined surface cooperates with the protrusion 604 for transmission.

[0055] Since the power column 7 can only move up and down under the limiting action of the limiting structure 8, the limiting plate 605 relatively fixedly connected to the power column 7 can only move up and down. When the protrusion 604 rotates, the limiting plate 605 is pushed downward through the inclined surface, and the limiting plate 605 drives the power column 7 to move downward. The protrusion 604 continues to rotate until it passes over the limiting plate 605. The protrusion 604 no longer limits the limiting plate 605, and the power column 7 is bounced up under the action of the elastic force of the elastic member.

[0056] In order to match the shape of the first limiting plate 401 and the shape of the sleeve 603 , the limiting plate 605 is configured as an arc-shaped plate, and the central axis of the arc-shaped plate is parallel to the central axis of the sleeve 603 .

[0057] In this embodiment, two limiting plates 605 are provided. The two limiting plates 605 are centrally symmetrically arranged on the first limiting plate 401 , and the symmetry centers of the two limiting plates 605 coincide with the center of the sleeve 603 .

[0058] According to actual needs, the rotating wheel 601 can select one of a pulley, a sprocket or a gear, and the corresponding driving mechanism can select one of a belt drive, a chain drive or a gear drive mechanism.

[0059] In order to ensure that the power column 7 moves in the vertical direction, the limiting structure 8 includes a guide rod 801 and a guide groove 802. The guide groove 802 is opened on the limiting plate 605 along the vertical direction. One end of the guide rod 801 is fixedly connected to the cylinder 5, and the other end is slidably set in the guide groove 802.

[0060] The method of use or working principle of this embodiment

[0061] When the bouncing device provided in this embodiment is in use, the driving mechanism drives the rotating wheel 601 to rotate. When the rotating wheel 601 rotates, the sleeve 603 rotates synchronously. The protrusion 604 on the sleeve 603 rotates with the sleeve 603. When the protrusion 604 rotates, it cooperates with the inclined surface of the limiting plate 605. Since the power column 7 can only move up and down under the limiting action of the guide rod 801 and the guide groove 802, the limiting plate 605 is relatively fixedly connected to the power column 7. Therefore, when the protrusion 604 rotates, it can drive the limiting plate 605 to move downward through the inclined surface, thereby driving the power column 7 to move downward to compress the first elastic member 2 or compress the first elastic member 2 and the second elastic member 3 to store energy. When the protrusion 604 rotates and passes over the limiting plate 605, the protrusion 604 no longer limits the limiting plate 605, and the elastic force of the first elastic member 2 or the first elastic member 2 and the second elastic member 3 is released to bounce the power column 7 to achieve bouncing.

[0062] The above disclosure is only a preferred specific embodiment of the present invention, but the embodiments of the present invention are not limited thereto, and any changes that can be conceived by technicians in this field should fall within the protection scope of the present invention.
