Description

Technical Field

[0001] This utility model relates to the field of engine starting, and in particular to an auxiliary starter and a starting plate for the auxiliary starter. Background Technology

[0002] Auxiliary starters are commonly used equipment in the field of agricultural machinery, mainly used to start engines. Auxiliary starters are divided into three types: hand-cranked, pull-plate type, and electric starter.

[0003] In the existing technology, the common method for hand-cranked auxiliary starters is to use a hand-cranked starter shaft to drive a coiled spring to store energy, and then release the potential energy of the coiled spring through a limiting mechanism to drive the pawl plate connected to the starter shaft to rotate. Several pawls are hinged on the pawl plate. During the rotation of the pawl plate, the pawls rotate and insert the starter cup, which in turn drives the starter cup to rotate, thereby starting the engine.

[0004] In existing methods, when starting the assisted start, the starting plate needs to be rotated to disengage its limiting part from the ratchet, thereby releasing the elastic potential energy of the coil spring. The rotation angle of the starting plate is often limited for safety reasons. However, the limiting mechanism in existing technologies has a limited lifespan. For example, Chinese patent CN207777045U uses a downward-facing flange (stop) on the starting plate. During rotation, the downward-facing stop impacts the stopping part. Prolonged use or excessive force during starting can cause the stop to deform or break, affecting the normal use of the product and posing a certain operational risk. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide an auxiliary starter and its starter plate, thereby solving the problem that the instability of the limiting structure affects the service life of the product in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a starting plate for an auxiliary starter, comprising a starting plate body, the starting plate body comprising a positioning part, a starting part and a mounting hole, characterized in that the starting plate body is further provided with a sleeve having a through hole, the sleeve being fixedly disposed at the bottom of the starting plate body, and the through hole of the sleeve corresponding to the mounting hole, the starting plate body being rotatably disposed on the auxiliary starter housing by the positioning pin passing through the mounting hole and the through hole of the sleeve, the side wall of the sleeve having a notch, and a stop part being provided at the notch of the side wall of the sleeve.

[0007] Furthermore, the stop portion is disposed on the side wall of the positioning post.

[0008] Furthermore, the stop portion is disposed on the housing of the auxiliary starter.

[0009] Furthermore, the starter plate body includes an upper plate and a lower plate, the positioning part of the lower plate includes a Z-shaped part, and rollers are provided at the Z-shaped parts of the upper plate and the lower plate.

[0010] Furthermore, the starting part is provided with a cable hole.

[0011] Furthermore, the starting part is provided with a flange, and the cable hole is provided on the flange of the starting part.

[0012] An auxiliary starter is also provided, comprising a starter chip of any of the aforementioned auxiliary starters.

[0013] The technical effects of this utility model are: 1. A sleeve is installed below the starter plate body. A notch is cut into the sleeve, which, in conjunction with a stop within the notch, limits the rotation angle of the starter plate. Furthermore, the notch-cut sleeve design provides significantly greater impact resistance compared to the flanged design in existing technologies. Therefore, the limiting mechanism provided by this solution is more stable, less prone to damage, has a longer service life, and a higher safety factor. Attached Figure Description

Detailed Implementation

[0016] The following embodiments of this utility model serve as inspiration. Through the following description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The scope of protection of this utility model is not limited to the contents of the claims and description.

[0017] The present invention will be further described with reference to the accompanying drawings: The starting plate of the auxiliary starter is mainly used to rotate the starter shaft when starting the auxiliary starter, restricting the ratchet and preventing reverse rotation to allow the coil spring to properly store energy. Once energy storage is complete, the starting plate needs to be moved to separate it from the ratchet, releasing the elastic potential energy of the coil spring. This energy drives the main shaft to rotate, further rotating the starter pawl assembly, causing the starter pawl to insert into the engine's starter cup, thus starting the engine. As patent CN207777045U has already provided a detailed explanation of the starting mechanism and auxiliary starter implementation principles, it will not be repeated here.

[0018] A starting plate for an auxiliary starter includes a starting plate body 100. The starting plate body 100 includes a positioning part 110, an starting part 120, and a mounting hole 130. The positioning part 110 is used to engage with a ratchet to prevent the ratchet from reversing and to realize the energy storage of the coiled spring. The starting part 120 is used to separate the positioning part 110 from the ratchet and to realize the release of the elastic potential energy of the coiled spring. The mounting hole 130 is used to mount the starting plate on a housing. The starting plate body 100 is also provided with a sleeve 140 with a through hole. The sleeve 140 is fixedly disposed at the bottom of the starting plate body 100, and the through hole of the sleeve 140 corresponds to the mounting hole 130. The starting plate body 100 is rotatably disposed on the auxiliary starter housing by a positioning pin 180 passing through the mounting hole 130 and the through hole of the sleeve 140. A notch 141 is opened on the side wall of the sleeve 140, and a stop part 150 is also provided at the notch 141 on the side wall of the sleeve 140. The stop part 150 is fixedly installed. When the starter plate is rotated, the notch 141 rotates relative to the stop part 150. When one side of the notch 141 abuts against the stop part 150, the starter plate is limited.

[0019] Of course, the stop 150 can be located on the side wall of the positioning post 180. Specifically, it can be located at the bottom or the middle of the side wall of the positioning post 180. For ease of installation, the bottom of the side wall of the positioning post 180 is the best location.

[0020] The stop portion 150 can also be provided on the housing of the auxiliary starter. Since the notch 141 of the sleeve 140 can be close to the housing of the auxiliary starter, providing the stop portion 150 on the housing can also achieve the effect of limiting the rotation angle of the starter plate.

[0021] The starter plate body 100 includes an upper plate 160 and a lower plate 170. The positioning part 110 of the lower plate 170 includes a Z-shaped part 171. Rollers 111 are provided at the Z-shaped parts 171 of the upper plate 160 and the lower plate 170. The rollers 111 are inserted between the two teeth of the ratchet. When the starter shaft is rotated, the rollers 111 and the ratchet achieve rolling friction, which reduces the friction force, facilitates starting, and also prevents the ratchet from reversing.

[0022] Since some agricultural machinery is started by remotely controlling the auxiliary starter with a handle, the starter part 120 of the auxiliary starter is connected to the handle by a cable. Therefore, the starter part 120 is provided with a flange 121, and the cable hole 122 is provided on the flange 121 of the starter part 120.

[0023] An auxiliary starter is also provided, comprising a starter chip of any of the aforementioned auxiliary starters.
