Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of starters of internal combustion engines, in particular to a water leakage pipe for starters. Background Art
[0002] The starter (starter motor) is an ignition and starting device for internal combustion engine vehicles. The stator of the starter is in a cylindrical state and has a magnetic field. There is a rotor inside to cooperate with it. When the starter is powered on, the rotor cuts the magnetic field to rotate itself. During the rotation, heat is continuously generated to increase the temperature of the starter. After the starter stops working, the temperature difference between the inside and outside of the starter will cause water vapor to be generated inside the starter. For the current starter, there is no dedicated water vapor discharge structure. Therefore, the water vapor will condense into water droplets inside the starter. After a long period of use, the water droplets will have an adverse effect on the internal structure of the starter. Therefore, how to discharge the water vapor inside the starter is the current problem. Summary of the invention
[0003] In view of the above problems, the utility model provides a water leakage pipe for a starter, which can easily discharge the water vapor inside the starter.
[0004] The technical solutions to the above technical problems are as follows:
[0005] A leaky water pipe for a starter, comprising:
[0006] A leaking pipe body, one end of which has an input port, the other end of which has an output port, and a card slot is arranged on the inner wall of the leaking pipe body;
[0007] The clamping component includes a clamping ring and a buckle. The clamping ring cooperates with the clamping groove. One end of the buckle is fixed to the clamping ring, and the other end of the buckle passes through the input port and is exposed outside the leaking pipe body.
[0008] Furthermore, it also includes a first anti-backflow component, which is fixed to a part of the inner wall of the leaking pipe body, and a first channel is formed between the first anti-backflow component and another part of the inner wall of the leaking pipe body.
[0009] Furthermore, it also includes a second backflow prevention component, which is fixed to the inner wall surface of the leaking pipe body and is provided with a second channel.
[0010] Furthermore, the output port is located on the peripheral surface of the leaking pipe body.
[0011] Furthermore, it also includes a first sealing lip and a second sealing lip. The first sealing lip is fixed to the leaking pipe body and surrounds the input port, and the second sealing lip is fixed to the leaking pipe body and surrounds the first sealing lip.
[0012] Furthermore, it also includes a reinforcing component, which is arranged on the circumferential surface of the leaking pipe body.
[0013] In the utility model, the leaking pipe is fixed on the starter by cooperating with the electromagnetic switch and the exhaust port on the rear end cover through the clamping component. Since the leaking pipe is provided with an input port and an output port, when there is water vapor or condensed water droplets in the starter, the water vapor or water droplets inside the starter will be discharged from the leaking hole. In addition, since the leaking pipe is provided with a first sealing lip and a second sealing lip structure, the leaking pipe can be in close contact with the electromagnetic switch and the rear end cover, effectively preventing water from entering the exhaust port. In addition, since the first anti-backflow component and the second anti-backflow component are provided in the utility model, the possibility of water entering the starter can be significantly reduced by preventing water from backflow through the first anti-backflow component and the second anti-backflow component, thereby protecting the starter from short circuit due to wading in water. It can be seen that the utility model is not only reliable and effective in exhausting steam and water, and has high sealing performance, but also is particularly suitable for RA type starters.

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0022] like Figures 1 to 4The utility model discloses a leaking pipe for a starter, comprising a leaking pipe body 1 and a clamping component 2. One end of the leaking pipe body 1 has an input port 1a, the other end of the leaking pipe body 1 has an output port 1b, and a clamping groove 1c is provided on the inner wall of the leaking pipe body 1; the input port 1a is located on the axial end face of one end of the leaking pipe body 1, the output port 1b is located on the circumferential surface of the leaking pipe body 1, and the clamping groove 1c is an annular groove.
[0023] The working environment of the starter is exposed in the engine compartment, and it is matched with both gasoline and diesel engines. Therefore, the working temperature of the starter is high, and it needs to be oil-resistant and waterproof. The material of the leakage pipe body 1 is preferably chloroprene rubber, which is oil-resistant and heat-resistant and aging-resistant, and meets the use conditions.
[0024] The clamping component 2 includes a clamping ring 2a and a buckle 2b. The material of the clamping component 2 is thermoplastic resin nylon 6. The thermoplastic resin nylon 6 has high mechanical strength, high wear resistance and heat resistance. The clamping ring 2a cooperates with the clamping groove 1c, one end of the buckle 2b is fixed with the clamping ring 2a, and the other end of the buckle 2b passes through the input port 1a and is exposed outside the leaking pipe body 1. The rear end cover 11 of the starter and the electromagnetic switch 13 are both provided with exhaust ports. The buckle 2b is clamped with the exhaust port. There are two buckles 2b. Applying a clamping force to the two buckles 2b can cause the two buckles 2b to deform, so that the buckles 2b are inserted into the exhaust port. The buckle 2b has a barb 2c, and a buckling part is provided on the inner wall surface of the exhaust port. After releasing the clamping force, the buckle 2b is reset, and the barb 2c cooperates with the buckling part, so that the clamping component 2 is fixed to the rear end cover 11 and the electromagnetic switch 13 as a whole.
[0025] After the water leakage pipe of the utility model is installed on the rear end cover 11 and the electromagnetic switch 13, the angle of the mounting hole of the drive cover 12 in the starter is adjusted to keep the water leakage pipe below the starter, thereby ensuring that water vapor will not accumulate inside the starter and protecting other mechanisms from damage.
[0026] The leaking pipe body 1 and the clamping component 2 are easy to assemble, and the two have a pull-out force of more than 19.6N after being combined. After the leaking pipe is assembled with the starter, it is ensured that the leaking pipe does not fall off.
[0027] The utility model further includes a first anti-backflow component 3, which is fixed to a part of the inner wall of the leaking pipe body 1, and a first channel 3a is formed between the first anti-backflow component 3 and another part of the inner wall of the leaking pipe body 1. When backflow enters the leaking pipe body 1 through the outlet 1b, the first anti-backflow component 3 forms an obstruction effect on the backflow water, which can significantly reduce the possibility of water entering the starter, thereby protecting the starter from short circuit due to the product wading in water.
[0028] The utility model further includes a second anti-backflow component 4, which is fixed to the inner wall of the leaking pipe body 1, and a second channel 4a is provided on the second anti-backflow component 4. The second anti-backflow component 4 is located between the first anti-backflow component 3 and the output port 1b. Similarly, when backflow enters the leaking pipe body 1 through the output port 1b, the second anti-backflow component 4 forms an obstruction to the backflow, which can significantly reduce the possibility of water entering the starter, thereby protecting the starter from short circuit due to the product wading in water.
[0029] The utility model further comprises a first sealing lip 5 and a second sealing lip 6. The first sealing lip 5 is fixed to the water leakage pipe body 1 and surrounds the input port 1a. The second sealing lip 6 is fixed to the water leakage pipe body 1 and surrounds the first sealing lip 5. The first sealing lip 5 and the second sealing lip 6 are made of the same material as the water leakage pipe body 1. When the water leakage pipe is installed on the rear end cover 11 and the electromagnetic switch 13, the rubber property is utilized to provide a certain amount of compression after assembly. The first sealing lip 5 and the second sealing lip 6 form a tight fit with the starter, effectively preventing water from entering the input port 1a.
[0030] The utility model further comprises a reinforcing component 7, which is arranged on the circumference of the leaking pipe body 1. The reinforcing component 7 can increase the strength of the leaking pipe body 1.
[0031] Finally, it should be noted that the above-described implementation mode is only a preferred embodiment of the utility model to illustrate the technical solution of the utility model, and does not limit it, let alone limit the protection scope of the utility model; although the utility model is described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solution deviate from the protection scope of the claims.
