Description

Technical Field

[0001] The utility model relates to the field of auxiliary starters, in particular to an electric starting auxiliary starter. Background Art

[0002] With the development of society, agricultural machinery has been widely used in my country, especially some small agricultural machinery. Agricultural machinery is mostly powered by diesel or gasoline engines. However, when starting, an auxiliary starter is needed to start the engine and make the agricultural machinery work. Currently, the auxiliary starters on the market are generally started by a manual pull disk or a manual cranking method.

[0003] When the auxiliary starter is started by means of a hand pull disk, it is necessary to pull the cable, and a certain force is required to pull the pull disk to effectively start the auxiliary starter driven by the cable.

[0004] Existing hand-crank assist devices, such as the auxiliary starter disclosed in CN109812367B and the auxiliary starter disclosed in CN110608122B, store energy in the hand-cranked start shaft through the cooperation of a ratchet, a stop plate, and a coil spring, and then release the energy to start the engine through the coil spring. This method is the same as the hand-pulled plate, and requires a certain amount of force to crank it manually. Since a large proportion of elderly people are now engaged in farming, there are certain problems. At the same time, for the hand-cranked auxiliary starter, it is necessary to set a related stop device, such as the stop plate of the patent cited in the background technology, and a coil spring is also required to complete the energy storage and release. In addition, since it involves the energy storage and release process, it is also necessary to consider whether the impact force between the pawl and the start cup will cause damage to the start cup. In general, the hand-cranked auxiliary starter has many parts and a relatively complex structure, and the extended part failure and product life are also affected to a certain extent.

DETAILED DESCRIPTION

[0029] The following is based on the ideal embodiment of the present invention. Through the following description, relevant personnel can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the content of the specification, but must be determined according to the scope of the claims.

[0030] The present invention will be further described with reference to the following drawings:

[0031] like Figure 1-2 As shown, an electrically started auxiliary starter includes an auxiliary starter housing 100 and a pawl assembly 300, and also includes a motor 200. The motor 200 is fixedly arranged inside the housing 100, and the power output shaft 220 of the motor 200 is connected to the pawl assembly 300. The motor 200 is connected to a power supply 400, and the power supply 400 is arranged in the housing 100 or on the housing 100. Specifically, the power supply 400 is arranged on the housing 100 through the power supply mounting portion 500. The power supply 400 is supplied to the motor 200, and the power supply 400 is connected through the starting portion and the motor 200 is started, causing the motor 200 to rotate. The motor 200 drives the pawl assembly 300 to rotate. The pawl assembly 300 then drives the engine to start.

[0032] The motor 200 is provided with a mounting base 210, which is used to securely mount the motor 200 inside the housing 100. Specifically, the mounting base 210 of the motor 200 is a pair of lugs provided on both sides of the motor 200, each of which has bolt holes, and the motor 200 is secured to the auxiliary starter housing 100 by bolts. Alternatively, the motor mounting base 210 can be snapped into the auxiliary starter housing 100 using a snap-fit structure. The auxiliary starter is equipped with a power supply 400, which can be provided inside the housing 100 or, for ease of replacement, can be provided on a power supply mounting portion 500 on the outside of the housing 100. The power supply 400 is a detachable charging device. When the power supply 400 is low on power, the power supply 400 can be recharged or replaced.

[0033] like Figure 3-4 As shown, the pawl assembly 300 includes a plurality of pawls 320, a pawl seat 330, and a stop cup 310. The pawls 320 are fixed or rotatably mounted on the pawl seat 330. The pawls 320 are primarily used to insert into the starter cup, driving the starter cup to rotate. Since this solution can omit the energy storage step via a coil spring compared to the prior art, the pawls 320 are not necessarily rotatable. It is sufficient to ensure that the pawls 320 insert into the starter cup to transmit power. Of course, allowing the pawls 320 to rotate at a certain angle can reduce the impact force between the pawls 320 and the starter cup to a certain extent.

[0034] The stopper cup 310 is positioned between the pawl seat 330 and the motor 200. The stopper cup 310 is provided with a pawl slot 311 and a pawl hole 312. The pawl seat 330 is positioned within the pawl slot 311 of the stopper cup 310. The pawl 320 extends outward from the pawl seat 330 and extends into the pawl hole 312. After extending through the pawl hole 312, the pawl 320 is inserted into the starter cup. When the pawl 320 rotates, it drives the starter cup to rotate, starting the engine.

[0035] like Figure 5 As shown, the pawl base 330 includes a first base plate 331 and a second base plate 332. The pawl 320 is disposed between the first base plate 331 and the second base plate 332 via a pin 333 extending through a pawl mounting hole. Since the pawl 320 is intended to be inserted into the starter cup to drive the starter cup to rotate, the pawl base 330 is merely a base plate, and the pawl 320 can be fixed or rotatably disposed on the pawl base 330.

[0036] To improve installation stability,

[0037] A corrugated spring piece 340 is provided between the limiting cup 310 and the pawl seat 330;

[0038] A flat washer 350 is provided between the limit cup 310 and the pawl seat 330;

[0039] A shaft retaining spring 360 is provided between the pawl seat 330 and the limiting cup 310;

[0040] The pawl seat 330 is provided with a flat washer 350 on a side away from the limiting cup 310;

[0041] The pawl seat 330 is provided with an open retaining ring 370 on a side away from the limiting cup 310 .

[0042] like Figure 6 As shown, in another embodiment, the limit cup 310 may include a left cup 310-1 and a right cup 310-2, and the left cup 310-1 and the right cup 310-2 are arranged opposite to each other. The pawl seat 330 is arranged inside the left cup 310-1 and the right cup 310-2 and fixes the left cup 310-1 and the right cup 310-2 to achieve the wrapping of the pawl 320 and the pawl seat 330, thereby improving safety.
