DETAILED DESCRIPTION
[0017] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.
[0018] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention. The figures only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.
[0019] Embodiment 1: like Figure 1 to Figure 11As shown, an energy storage-started engine comprises an engine body 1 and a hand-pull disc structure 2, wherein the hand-pull disc structure 2 is transmission-connected with the engine body 1 and used to drive the shaft body in the engine body 1 to rotate, and in this example, the shaft body inside the engine body 1 is a crankshaft; it is characterized in that the hand-pull disc structure 2 comprises a pull disc housing 21, a pull rope, a pulley 23, a pawl 24, a power storage disc spring box 25, a one-way bearing 26 and a transmission structure 27 for transmission connection with the engine body 1; wherein the pull disc housing 21 is fixedly connected with the engine body 1, and a connecting shaft 211 for connecting the pulley 23 and the power storage disc spring box 25 is provided on the pull disc housing 21; the pulley 23 is rotationally arranged on the connecting shaft 211, and a pull rope is also wound around the pulley 23; one side of the pulley 23 is close to the inner wall of the pull disc housing 21, and the other side of the pulley 23 is provided with the power storage disc spring box 25; a pulley 23 is provided between the pulley 23 and the pull disc housing 21 A first coil spring is used to help the rope pulley 23 to retract the pull rope; the energy storage coil spring box 25 is rotatably set on the connecting shaft 211 through a one-way bearing 26. It should be noted that the rotation direction of the one-way bearing 26 is consistent with the rotation direction when the rope pulley 23 pulls the pull rope; a first ratchet 251 is arranged on the side of the energy storage coil spring box 25 close to the rope pulley 23; a pawl 24 corresponding to the first ratchet 251 is arranged on the side of the rope pulley 23 close to the energy storage coil spring box 25, and the pawl 24 abuts against the first ratchet 251, so that when the rope pulley 23 rotates following the pulling of the pull rope, the cooperation between the pawl 24 and the first ratchet 251 can drive the energy storage coil spring box 25 to rotate; a transmission structure 27 is arranged on the side of the energy storage coil spring box 25 away from the rope pulley 23; the transmission structure 27 is rotatably set on the connecting shaft 211; a second coil spring for storing elastic force is also arranged between the transmission structure 27 and the energy storage coil spring box 25; the transmission structure 27 is also transmission-connected to the engine body 1. During implementation, the pull rope is pulled and the rope wheel 23 is driven to rotate, and the rope wheel 23 then presses against the ratchet on the force storage coil spring box 25 through the pawl 24, so that the force storage coil spring box 25 rotates with the rope wheel 23. After the force storage coil spring box 25 rotates, it drives the second coil spring to reel in, and transmits the rotational force to the transmission structure 27 through the second coil spring; then, when the rope wheel 23 is acted upon by the first coil spring to retract the pull rope, the force storage coil spring box 25 is difficult to rotate in the opposite direction due to the action of the one-way bearing 26, so the force storage coil spring box 25 will not rotate back, and the second coil spring continues to release the stored elastic force, and uses the elastic force to push the transmission structure 27 to continue to rotate; then the process of pulling the pull rope is repeated, so that the transmission structure 27 can drive the shaft body to maintain continuous rotation. It should be noted that when the elastic force stored in the second coil spring is too much, the force storage disc spring box 25 can drive the one-way bearing 26 to rotate on the connecting shaft 211. Although the one-way bearing 26 can only rotate in one direction, the one-way bearing 26 and the connecting shaft 211 are connected by friction. Therefore, the one-way bearing 26 can overcome the friction and rotate in the opposite direction to protect the second coil spring from damage.
[0020] The rope wheel 23 is rotatably provided with two pawls 24, and the two pawls 24 are rotationally symmetrically arranged about the center of the rope wheel 23; the pawls 24 cooperate with the first ratchet 251 on the power storage coil spring box 25, so that when the rope wheel 23 rotates following the pull rope, the pawls 24 abut against the first ratchet 251, driving the power storage coil spring box 25 to rotate. The rope wheel 23 is also provided with a raised connecting column 232, and the connecting column 232 is used to rotate and connect the pawl 24; a torsion spring is also provided between the pawl 24 and the rope wheel 23 to help the pawl 24 reset, and under the action of the torsion spring, the pawl 24 is always in close contact with the outer side of the first ratchet 251 on the power storage coil spring box 25.
[0021] The middle part of the energy storage disc spring box 25 is provided with an embedding hole 252 for embedding the one-way bearing 26; the embedding hole 252 is a cylindrical concave hole as a whole, and the bottom of the embedding hole 252 is also provided with a through hole for passing the connecting shaft 211; wherein the one-way bearing 26 is located in the embedding hole 252, and the connecting shaft 211 passes through the one-way bearing 26 and the through hole at the bottom of the embedding hole 252 respectively. The side wall of the embedding hole 252 is provided with a raised clamping strip 253, which abuts against the outer side surface of the one-way bearing 26 to clamp the one-way bearing 26; the extending direction of the clamping strip 253 is parallel to the central axis of the embedding hole 252. In this example, the outer side of the one-way bearing 26 is provided with a clamping groove 261 matching the clamping strip 253, and the extension direction of the clamping groove 261 is parallel to the axis of the one-way bearing 26, so that the clamping strip 253 can be embedded in the clamping groove 261, ensuring the relative position stability of the one-way bearing 26 and the power storage disc spring box 25, and preventing the one-way bearing 26 from rotating in the embedding hole 252. The end of the clamping strip 253 close to the opening of the embedding hole 252 is also provided with a rounded corner, which facilitates the installation of the one-way bearing 26 in the embedding hole 252 and enables the clamping groove 261 on the one-way bearing 26 to form a match with the clamping strip 253.
[0022] The one-way bearing includes a bearing sleeve 262, a needle roller 263, an elastic sheet and a sealing sheet 265; the bearing sleeve 262 is generally annular and cylindrical, and a movable groove 266 is provided on the side close to the inner wall of the bearing sleeve 262, and the movable groove 266 is used to provide a movable space for the needle roller 263; the movable groove 266 is also provided with a square hole 264 on the side close to the inside of the bearing sleeve 262, and the square hole 264 connects the inner side of the bearing sleeve 262 and the movable groove 266; it should be noted that the two ends of the movable groove 266 are at different distances from the inner wall of the bearing sleeve 262, and the square hole 264 is located at one end of the movable groove 266 close to the inner wall of the bearing sleeve 262; the needle roller 263 is generally cylindrical, and the needle roller 263 is located in the movable groove 266, and the outer circumferential arc surface of the needle roller 263 can pass through the square hole 264 and enter the bearing The area inside the sleeve 262 is used to clamp the connecting shaft passing through the bearing sleeve 262, but the aperture of the square hole 264 is smaller than the outer diameter of the needle roller 263 to prevent the needle roller from escaping from the movable groove from the square hole; an elastic sheet is also provided in the movable groove 266, and the two ends of the elastic sheet respectively abut against the inside of the movable groove 266 and the needle roller 263, and are used to push the needle roller 263 to the end of the movable groove 266 where the square hole 264 is provided; a sealing sheet 265 is provided at the end of the bearing sleeve 262, and is used to cover the end of the needle roller 263 and seal the needle roller 263 in the movable groove 266. In this example, one end of the movable groove passes through the bearing sleeve, and the other end is in the bearing sleeve, and the sealing sheet 265 is located on the side where the movable groove passes through the bearing sleeve; in this example, seven movable grooves 266 are provided on the bearing sleeve 262, which are rotationally symmetrical about the axis of the bearing sleeve 262. The elastic sheet is V-shaped as a whole, and the elastic sheet is located on the side of the movable groove 266 away from the square hole 264. The clamping groove is located on the outer periphery of the bearing sleeve 262 , and the direction of the clamping groove is parallel to the axis of the bearing sleeve 262 . When the connecting shaft passes through the one-way bearing, when the connecting shaft rotates toward the side of the movable groove 266 away from the one-way bearing where the elastic sheet is provided, the needle roller 263 is pressed against the square hole 264 by the force of the elastic sheet. As the one-way bearing rotates, the needle roller 263 in the movable groove 266 continues to be pushed toward the side of the movable groove 266 away from the elastic sheet. When the one-way bearing moves in the direction away from the elastic sheet, the one-way bearing is restricted by the movement of the movable groove 266, and more parts are exposed to the square hole 264, further squeezing the connecting shaft inside the bearing sleeve 262 to achieve clamping of the connecting shaft; conversely, when the connecting shaft rotates toward the side of the elastic sheet, the part of the needle roller 263 exposed to the square hole 264 is affected by the friction force of the connecting shaft and moves toward the direction of the elastic sheet provided in the movable groove 266. At this time, the part of the needle roller 263 exposed to the square hole 264 is reduced, making it difficult for the needle roller 263 to clamp the connecting shaft, thereby achieving one-way rotation.
[0023] A handle is also provided at the end of the pull rope away from the rope wheel 23; the handle includes a rope connecting frame 222 and a grip 223; a notch 224 for embedding the rope connecting frame 222 is provided on the grip 223; in this example, the overall shape of the grip 223 is T-shaped, and a T-shaped hollow groove is provided in the middle area of the grip 223 as the notch 224. The pull rope is wound around the rope connecting frame 222 and then inserted into the grip 223 to achieve the connection between the handle and the pull rope; a first rope hole connecting the outer side of the grip 223 and the inside of the notch 224 is also provided on the grip 223; a second rope hole for connecting the pull rope is provided on the rope connecting frame 222.
[0024] The transmission structure 27 includes a second ratchet 271 , which is in transmission connection with the engine body 1 , so that the transmission structure 27 can drive the shaft in the engine body 1 to rotate, and after the engine is started, the rotation of the shaft will not affect the transmission structure 27 .
[0025] The end of the connecting shaft 211 away from the connecting pull plate housing 21 is provided with a flat washer 272 for limiting, and the flat washer 272 is fixedly connected to the connecting shaft 211 by screws; the flat washer 272 limits the transmission structure 27, the power storage coil spring box 25 and the rope pulley 23 on the connecting shaft 211. In this example, a spring washer is also provided between the flat washer 272 and the transmission structure 27 to prevent the screws from loosening and falling off due to the vibration generated by the operation of the engine body 1.
[0026] The pull tray housing 21 is also provided with a rope hole for passing a pull rope. In addition, a nameplate 28 is also provided on the pull tray housing 21 to indicate product information and name.
[0027] During the implementation process, by setting a force storage disc spring box 25 in conjunction with the one-way bearing 26 and the second coil spring, the pulling force is converted into the elastic force of the second coil spring for storage and continuous release, so as to keep the shaft of the engine body 1 able to maintain rotation and facilitate starting the engine; by setting a pawl 24 in conjunction with the first ratchet 251, the rope wheel 23 can drive the force storage disc spring box 25 to rotate in one direction, and reduce the interference to the force storage disc spring box 25 when the rope wheel 23 retracts the pull rope; by setting a clamping strip 253 in the embedding hole 252 of the force storage disc spring box 25, in conjunction with the clamping groove 261 on the one-way bearing 26, the one-way bearing 26 can be kept able to rotate stably with the force storage disc spring box 25; by setting a needle roller 263 in the one-way bearing in conjunction with the elastic sheet and the movable groove 266 structure, the one-way rotation of the one-way shaft when it is sleeved on the connecting shaft is realized.
[0028] The above description is only a specific example of the present invention and does not constitute any limitation to the present invention. It is obvious that for professionals in this field, after understanding the content and principle of the present invention, various modifications and changes in form and details may be made without departing from the principle and structure of the present invention, but these modifications and changes based on the idea of the present invention are still within the scope of protection of the claims of the present invention.
