Description

Technical Field

[0001] The utility model relates to the technical field of mechanical energy storage, in particular to a single-direction reciprocating energy storage release device. Background Art

[0002] With the continuous innovation and development of science and technology, there are different ways to store energy for utilization, such as hydraulic energy storage, spring energy storage, mechanical energy storage, etc., and different energy storage methods can be applied in different scenarios. For example, in the patent document with Chinese patent application number 202310735874.0 and publication date 2023.08.25, a coil spring type human walking energy collector is disclosed, including a transmission mechanism, a stroke control mechanism, and a power generation mechanism; the transmission mechanism includes a coil spring, an angle limit unit, a one-way ratchet, a gear pair, a flywheel, a transmission shaft and a corresponding support shell; the stroke control mechanism includes two sets of slide rail sliders, a pull ring, a clamping unit, a limit guide wheel and corresponding connecting parts; one part of the power generation mechanism is a small DC motor energy storage mechanism connected to the driven shaft, and the other part is a piezoelectric mechanism composed of a clamped piezoelectric cantilever beam and a pull ring.

[0003] The above-mentioned patent documents mainly focus on the characteristics of coil spring energy storage and release, which converts the kinetic energy generated by walking into electrical energy and deformation energy. It is necessary to pull the coil spring through a pull ring to tighten the coil spring, and then release energy through the coil spring after the coil spring is tightened to drive the active shaft to rotate and drive the driven shaft to rotate. The rotation limit of the active shaft can only be adjusted by the downward pulling distance of the pull ring, which results in low reliability of the limit. At the same time, since the coil spring energy storage can only be achieved by pulling the pull ring downward, the entire device requires a certain distance in the height direction, which causes the entire device to occupy a larger space, affecting the arrangement of the drive motor in the robot space and increasing the use cost of the robot. Utility Model Content

[0004] The utility model aims to provide a unidirectional reciprocating energy storage and release device, which stores energy by rotatingly connecting with an external input part and limits position by a limit device, and has a simple structure and high reliability.

[0005] The utility model provides the following technical solutions: a single-direction reciprocating energy storage and release device, comprising a ratchet, a coil spring, a partial gear structure, a limit device and a rotating shaft body, one end of the rotating shaft body passes through a through hole in the middle of the partial gear structure body and is rotatably connected to the partial wheel structure body through a bearing, one side of the partial gear structure body protrudes outward along the direction of the axis to form an extension end, the extension end and the end face of the partial gear structure form a receiving cavity, one end of the coil spring arranged in the receiving cavity is clamped on a slot 1 of the rotating shaft body, and the other end of the coil spring is clamped on a slot 2 of the extension end, the ratchet located in the receiving cavity is fixed on the rotating shaft body, the limit device is arranged on the extension end, and a receiving groove is arranged on the extension end near the ratchet, a limit cone is arranged on the limit device, the limit cone is meshed with the ratchet, and when the coil spring stores energy, the limit cone swings in the receiving groove under the action of the limit device.

[0006] The above arrangement is to arrange a rotating shaft body to pass through a partial gear structure body and then be rotatably connected to the partial gear structure body through a bearing. In this way, when an external driving source drives the partial gear structure body to rotate, the partial gear structure body and the rotating shaft body rotate relative to each other, and then the partial gear structure drives the coil spring to store energy. An extension end is arranged on the partial gear structure body, and a receiving cavity is formed between the extension end and the end face of the partial gear structure body, so that it is convenient to arrange the coil spring in the receiving cavity, and a slot one is arranged on the rotating shaft body, and a slot two is arranged on the extension end, so that one end of the coil spring can be clamped on the rotating shaft body, and the other end of the coil spring can be clamped on the extension end. In the process of rotation of the partial gear structure body, the coil spring is driven to store energy. In the process of energy storage, due to the ratchet Fixed on the rotating shaft, the limiting cone swings in the accommodating groove, so that the ratchet does not rotate. Then, when the partial gear structure rotates to a position without a gear, the driving device does not mesh with the partial gear structure, so that the driving device is in an unloaded state, so that the coil spring relaxes and releases energy, so that the partial gear structure rotates in the opposite direction. Since the limiting cone meshes with the ratchet, the limiting cone drives the ratchet to rotate in the opposite direction. In this way, the ratchet can be axially limited during the coil spring energy storage process through the limiting device, and the ratchet can be driven to rotate when the coil spring is in a relaxed state, so that other components can be driven through the ratchet. Since the limiting device is arranged in the accommodating cavity, there is no need to set a longer stretching space, and the structure is simple and reliable.

[0007] Furthermore, the rotating shaft body includes an end portion, a rotating shaft and a sleeve, the sleeve is fixedly sleeved on the rotating shaft, one side of the end portion is respectively fixedly connected to one end of the rotating shaft and one end of the sleeve, and a slot is provided on the other end of the sleeve.

[0008] With the above arrangement, after the rotating shaft body passes through a part of the gear structure, the end portion plays a limiting role in the axial direction, and can also enable the coil spring to be sleeved in the sleeve to avoid abutment with the ratchet.

[0009] Furthermore, the length of the rotating shaft is greater than the length of the sleeve, and the diameter of the end portion is greater than the diameter of the sleeve.

[0010] With the above arrangement, after the coil spring is sleeved on the sleeve, the ratchet is fixed on the rotating shaft, isolating the coil spring from contacting the ratchet.

[0011] Furthermore, a through hole is provided on part of the gear structure at the extension end, and the limiting device includes a fixing member matching the through hole, a locking member matching the fixing member, a spring, and a limiting member sleeved on the fixing member, and a receiving groove matching the limiting member is provided on the extension end, the limiting member rotates around the fixing member in the receiving groove, and the spring is connected to the bottom of the limiting member.

[0012] The above arrangement makes it easy for the fixing part to pass through the through hole, and then match the fixing part with the locking part to limit the axial position of the limit part. Then the spring is connected to the bottom of the limit part, so that the limit part can be swung and restored by the elastic force of the spring, thereby fixing the entire limit device on a part of the gear structure.

[0013] Furthermore, the limiting member comprises a limiting block, the outer side of the limiting block protrudes outward and extends to form a limiting cone, and the inclination direction of the limiting cone is matched with the inclination direction of the ratchet strip on the ratchet wheel.

[0014] With the above arrangement, after the partial gear structure drives the limit block to rotate around the fixing part to compress the coil spring energy storage and complete the neutral rotation period, the limit block and the ratchet bar of the ratchet can be matched to drive the ratchet to rotate.

[0015] Furthermore, one end of the limit block extends outward along the axial direction to form a straight tube, and a rib block connected to a spring is fixedly provided on the outside of the straight tube. A spacing is provided between the rib block and the limit cone and they are arranged side by side.

[0016] The above arrangement makes it easy for the tendon block to compress the spring by rotating with the straight tube after being connected to the spring.

[0017] Furthermore, one side of the rib block is recessed inwardly along the thickness direction of the rib block to form a limiting groove, one end of the spring is fixed in the limiting groove, and the other end of the spring is fixedly connected to the inner side of the accommodating groove.

[0018] The above arrangement prevents the spring from slipping and deviating from contact with the limit cone during the compression process, and at the same time enables the limit block to be reset after rotation through the spring.

[0019] Furthermore, a gear area and a gearless area are provided on the outer wall of a part of the gear structure, the gear area is provided with gears, and the gearless area is provided with an outer side wall, and the arc length of the gear area is 3:1 to the arc length of the gearless area.

[0020] The above arrangement, by arranging a gearless area on a part of the gear structure, enables the part of the gear structure to perform an idling period when it rotates to a certain position, thereby facilitating the resetting of the ratchet. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figure 1-5 As shown, the utility model provides a single-direction reciprocating energy storage release device, including a ratchet 1, a coil spring 2, a partial gear structure 3, a limit device and a rotating shaft body, one end of the rotating shaft body passes through a through hole (not marked in the figure) in the middle of the partial gear structure 3 and is rotatably connected to the partial gear structure 3 through a bearing 4, the rotating shaft body includes an end 11, a rotating shaft 12 and a sleeve 13, the sleeve 13 is fixedly sleeved on the rotating shaft 12, one side of the end 11 is fixedly connected to one end of the rotating shaft 12 and one end of the sleeve 13 respectively, and a slot 14 is provided on the other end of the sleeve 13.

[0028] In this embodiment, the length of the rotating shaft 12 is greater than the length of the sleeve 13, so that the ratchet 1 is fixed on the rotating shaft 12, and the coil spring 2 is sleeved on the sleeve 13 to prevent the coil spring 2 from contacting the ratchet 1. The diameter of the end 11 is greater than the diameter of the sleeve 13, and the end 11 is configured as a disc. In this way, after the rotating shaft body passes through the partial gear structure 3, the end 13 plays a limiting role in the axial direction. The outer wall of the partial gear structure 3 is provided with a gear area and a gearless area, and the gear area is provided with gears, and the gearless area is only provided with an outer wall without gears. The arc length of the gear area and the arc length of the gearless area are 3:1.

[0029] like Figure 2 and 3As shown, one side of the partial gear structure 3 protrudes outward along the direction of the axis to form an extension end 31, and the extension end 31 and the end face of the partial gear structure 3 form a accommodating cavity 32, one end of the coil spring 2 arranged in the accommodating cavity 32 is clamped on the slot 14 of the sleeve 13, and the other end of the coil spring 2 is clamped on the slot 2 33 of the extension end 31, and the ratchet 1 located in the accommodating cavity 32 is fixed on the rotating shaft 12, a through hole is provided on the partial gear structure 3 at the position of the extension end 31, and an accommodating groove is provided on the extension end 31 near the ratchet 1, and a limiting cone 51 is provided on the limiting device, and the limiting cone 51 is meshed with the ratchet 1. When the coil spring 2 stores energy, the limiting cone 51 swings in the accommodating groove under the action of the limiting device.

[0030] like Figure 4 As shown, the limiting device includes a fixing member 21 matching the through hole, a locking member 22 matching the fixing member 21, a limiting member 5 sleeved on the fixing member 21, and a spring (not shown in the figure). The fixing member 21 passes through the through hole and matches the locking member 22, so that the limiting member 5 can be fixed on the partial gear structure 3. In this embodiment, the fixing member 21 is configured as a bolt, and the locking member 22 is configured as a nut matching the bolt. A receiving groove 34 matching the limiting member 5 is provided on the extending end 31 of the partial gear structure 3. When the partial gear structure 3 is driven to rotate under external input drive, the limiting member 5 can be driven to swing around the fixing member 21 in the receiving groove 34.

[0031] like Figure 4 As shown, the limit member 5 includes a limit block 51, and the outer side of the limit block 51 protrudes outward and extends to form a limit cone 52. After the partial gear structure 3 drives the limit block 51 to rotate around the fixing member 21 to compress the coil spring 2 to complete the energy storage and enter the neutral rotation period, the ratchet 1 can be driven to rotate under the action of the limit block 5.

[0032] like Figure 4 As shown, one end of the limit block 51 extends outward along the axial direction to form a straight tube 53, and a rib block 54 connected to the spring is fixedly provided on the outer side of the straight tube 53. A spacing is provided between the rib block 54 and the limit cone 52 and they are arranged side by side. One side of the rib block 54 is recessed inward along the thickness direction of the rib block 54 to form a limit groove 55. One end of the spring is fixed in the limit groove 55, and the other end of the spring is fixedly connected to the inner side of the accommodating groove 34, which can prevent the spring from slipping and deviating from the contact with the limit cone 52 during the compression process. At the same time, the limit block 51 can be reset after rotation through the spring. In this embodiment, the restoring force of the coil spring 2 is greater than the resistance of the ratchet 1 and the limit cone 51 to it.

[0033] The working principle of the utility model is as follows: the output end of an external power source such as a driving motor (not shown in the figure) can be connected to the transmission gear 01, thereby driving the transmission gear to rotate, and at the same time making the transmission gear mesh with the partial gear structure 3 to rotate externally. When the driving motor drives the transmission gear to rotate clockwise, it can drive the partial gear structure 3 to rotate counterclockwise. During the rotation, since the ratchet is fixed on the rotating shaft, the ratchet 1 does not rotate, and the limiting cone 52 is subjected to the force of the ratchet during the rotation, so that the spring is compressed and drives the limiting cone to swing in the receiving groove. When there is no blocking force from the ratchet, the limiting cone 52 resets, so that the limiting cone 52 swings in the receiving groove, so that the limiting cone 52 does not engage with the ratchet. 1 is abutted against the edge, so that the ratchet 1 does not rotate, thereby limiting the coil spring in the axial direction. At the same time, the partial gear structure 3 rotates to drive the coil spring 2 to be compressed, thereby storing energy in the compression spring 2. This process is repeated until the coil spring 2 in the accommodating cavity 32 is completely wound up to store energy and the partial structure 3 enters the gearless area, so that the drive motor enters the no-load area. After the drive motor stops inputting, the coil spring 2 releases energy. In this process, the coil spring 2 drives the partial structure 3 to rotate clockwise. Since the limiting cone 51 is engaged with the ratchet 1, the ratchet 1 is driven to rotate clockwise, and at the same time, the external structure connected to the rotating shaft 12 is driven to complete the corresponding action, such as the leg structure of the jumping robot (not shown in the figure), so that the jumping action can be completed.
