Description
Technical Field
The present application relates to an electromagnetic switch for a starter and a starter including the same.
Background
Generally, an automobile engine is operated by starting a starter. The starter mainly comprises a direct current motor, an electromagnetic switch and a one-way clutch. On the one hand, the electromagnetic switch pushes the one-way clutch to slide forward along the drive shaft to engage with a large disk of the engine in accordance with a command from the ignition switch. On the other hand, the electromagnetic switch turns on or off the power supply to the dc motor.
In some applications, electromagnetic switches are all required to be of a closed design. With this closed design of the electromagnetic switch, the gas pressure will gradually increase because the gas inside the electromagnetic switch cannot be exhausted. Especially, when the starter is in a high-temperature environment, the high air pressure inside the electromagnetic switch may cause the electromagnetic switch to be unable to be attracted.
The arrangement of the exhaust valve on the switch cover of the electromagnetic switch is a commonly used means for solving the technical problems, and the exhaust valve achieves the purpose of only allowing gas to pass through but not allowing water and other substances to pass through.
Fig. 1 shows a vent valve structure used in the prior art. The exhaust valve 10 is installed in a hole section 17a with a larger diameter of an installation hole 17 formed in the open/close cover 15, and a hole section 17b with a smaller diameter of the installation hole 17 plays a role in positioning the exhaust valve 10 in the axial direction.
The exhaust valve 10 includes a rubber member 12 and a gas permeable membrane 14. The rubber member 12 is of a substantially cylindrical shape and includes outwardly projecting teeth 16 on an outer peripheral surface, and correspondingly, inwardly projecting teeth 19 on an inner peripheral surface of a larger diameter hole section 17a of the mounting hole 17. The innermost dimension D of the teeth 19 is slightly larger than the outer diameter of the outer peripheral surface of the rubber member 12, and the outermost dimension D of the teeth 16 is larger than the inner diameter of the hole section 17a of the mounting hole 17 having a larger diameter. When the exhaust valve 10 is fitted into the large-diameter hole section 17a of the mounting hole 17, the teeth 16 on the outer peripheral surface of the rubber member 12 are elastically deformed between the adjacent teeth 19 by the inner wall of the large-diameter hole section 17a of the mounting hole 17 to form an interference fit.
The gas permeable membrane 14 is adhered to the rubber 12 and sandwiched between the rubber 12 and the shoulder of the mounting hole 17 after the exhaust valve 10 is mounted in place. In this way, the air inside the electromagnetic switch 10 is discharged out of the electromagnetic switch through the air permeable film 14 and the internal air vent 18 of the rubber member 12.
However, in the exhaust valve 10, the teeth 19 of the mounting hole 17 of the open/close cover 15 are protruded from the inner surface, which is difficult to process and expensive, and more importantly, cannot be achieved by domestic suppliers. Moreover, the exhaust valve is not ideally fixed in the mounting hole 17, and particularly after long-time use, the exhaust valve is easily driven out of the switch cover under the action of high air pressure in the electromagnetic switch, so that the electromagnetic switch fails.

The foregoing and other features, aspects, and advantages of the present application will become more apparent upon reading the following description of preferred embodiments of the present application, taken in conjunction with the accompanying drawings, in which:
FIG. 1 illustrates a discharge valve structure of a starter solenoid switch according to the prior art; and
fig. 2 is a structure of an exhaust assembly of a starter solenoid switch according to a preferred embodiment of the present application.
Detailed Description
An exhaust assembly according to a preferred embodiment of the present application for use in an electromagnetic switch of a starter, particularly for use in an electromagnetic switch of a vehicle starter, is described below with reference to fig. 2.
In fig. 2, an exhaust assembly for a starter solenoid switch is denoted by reference numeral 20, and fig. 2 also shows a switch cover 50 of the solenoid switch, and a mounting hole for mounting the exhaust assembly 20 is formed in the switch cover 50. The switch cover 50 includes a first surface 50a, i.e., an inner surface, facing the interior components of the electromagnetic switch, and an opposite second surface 50b, i.e., an outer surface, facing away from the interior components of the electromagnetic switch.
The mounting hole for mounting the exhaust assembly 20 includes three portions: a first bore section 52 adjacent the first surface 50a of the switch cover 50, a third bore section 56 adjacent the second surface 50b of the switch cover 50, and a second bore section 54 located between the first bore section 52 and the third bore section 56, wherein the second bore section 54 has an inner diameter less than the inner diameters of the first bore section 52 and the third bore section 56. A first step 63 is formed between the first and second bore sections 52, 54 and a second step 65 is formed between the third and second bore sections 56, 54.
The vent assembly 20 generally includes a plug 30 and a permeable element 40.
The plug 30 is made of an elastic material, such as soft rubber or any other suitable elastic material. The plug 30 is formed with a through hole 35 serving as an exhaust hole for allowing gas in the electromagnetic switch to be exhausted out of the electromagnetic switch. For example, the through hole 35 is a tapered hole gradually expanding from the first surface 50a of the open/close cover 50 toward the second surface 50b of the open/close cover 50 to enhance the air discharge effect.
The permeable element 40 is attached to the end surface of the plug 30 close to the first surface 50a, for example by gluing or laser welding, or by other attachment means. The air-permeable element 40 is an element through which air can pass but through which water and other substances cannot pass. The ventilation element 40 may be provided as a membrane, such as a gas permeable membrane, or as a plate, such as a gas permeable plate, or any other element having a ventilation function.
In correspondence with the mounting hole formed on the opening and closing cover 50 including three hole sections, the plug 30 also includes three portions having three different diameters: a first portion 32 adjacent the first surface 50a of the switch cover 50 and having an outer diameter slightly smaller than the inner diameter of the first bore section 52, a third portion 36 adjacent the second surface 50b of the switch cover 50 and having an outer diameter slightly smaller than the inner diameter of the third bore section 56, and a second portion 34 between the first portion 32 and the third portion 36. Similarly, a first step is formed between the first portion 32 and the second portion 34, and a second step is formed between the third portion 36 and the second portion 34.
A plurality of teeth 38 are formed on the outer peripheral surface 34a of the second portion 34 to project outwardly therefrom, and the outermost diameter of the teeth 38 is larger than the inner diameter of the second bore section 54 of the switch cover 50. Preferably, each tooth 38 extends the entire circumference of the second portion 34 of the plug 30 in the circumferential direction of the second portion 34, or each tooth 38 includes a plurality of extending segments evenly spaced in the circumferential direction of the second portion 34 of the plug 30. Optionally, each tooth 38 extends helically continuously or intermittently on the outer peripheral surface 34a of the second portion 34 of the plug 30. The cross-sectional shape of the teeth 38 may be triangular as shown in fig. 2, alternatively, square, trapezoidal, or any other shape may be used.
When the plug 30 is mounted in the hole of the switch cover 50, the plug 30 is pressed into the mounting hole from the first surface 50a side of the switch cover 50. After passing through the first bore section 52 of the mounting bore of the switch cover 50, the third portion 36 of the plug 30 enters the second bore section 54, and since the outer diameter of the third portion 36 of the plug 30 is greater than the inner diameter of the second bore section 54 and the outermost diameter of the teeth 38 is also greater than the inner diameter of the second bore section 54, the third portion 36 of the plug 30 and the teeth 38 on the second portion 34 both pass through in a crushed shape as the plug 30 passes through the second bore section 54 of the switch cover 50. After the third portion 36 of the plug 30 passes the second bore section 54, the third portion 36 of the plug 30 is restored by virtue of the resilient action of the material forming the plug 30.
At this time, the second step between the third portion 36 and the second portion 34 of the plug 30 abuts against the second step 65 of the switch cover 50, indicating that the plug 30 is mounted in place. Also, at this time, the first step portion between the first portion 32 and the second portion 34 of the shutter 30 abuts on the first step portion 63 of the opening and closing cover 50. This abutment corresponding to the first step portion prevents the plug 30 and the gas permeable element 40 attached to the plug 30 from being pressed out of the mounting hole of the switch cover 50 in the gas discharge direction from the first surface 50a toward the second surface 50b by the gas pressure inside the electromagnetic switch during use, avoiding the electromagnetic switch from failing due to detachment of the exhaust assembly 20.
With the exhaust assembly 20 according to the present application, the abutment between the second step portion of the plug 30 and the second step portion 65 of the switch cover 50 enables the positioning of the plug 30 within the mounting hole of the switch cover 50, while the abutment between the first step portion of the plug 30 and the first step portion 63 of the switch cover 50 ensures that the exhaust assembly 20 is not forced out of the through hole of the switch cover 50 by excessive gas pressure inside the electromagnetic switch.
Providing the compressively deformable teeth 38 on the second portion 34 of the plug 30 further ensures an interference fit between the second portion 34 of the plug 30 and the second bore section 54 of the switch cover 50, preferably forming a gas-tight seal between the plug 30 and the switch cover 50, without having to machine teeth on the inner surface of the second bore section 54 of the switch cover 50 that mate with the teeth 38 on the second portion 34 of the plug 30, as in the prior art, which greatly simplifies the manufacture of the switch cover 50, and correspondingly reduces the machining cost of the switch cover 50.
Through the corresponding abutment of the first step portions and the interference fit between the second portion and the second hole section, the exhaust assembly 20 can be securely mounted on the switch cover, and the reliability of the design is improved.
Through set up above-mentioned structure on closed electromagnetic switch's switch cover, the air in the electromagnetic switch can be discharged electromagnetic switch in time, prevents to take place because the rising of the interior gas pressure of electromagnetic switch leads to discharging the danger that the subassembly roll-off switch cover and consequently electromagnetic switch became invalid.
Here, it should be noted that while the plug of the exhaust assembly is illustrated as including three generally cylindrical shaped portions in the illustrated embodiment of the invention, it should be understood that the plug portions need not be cylindrical in shape as illustrated, and that plugs of elastomeric material having other cross-sectional shapes can perform the same function.
The electromagnetic switch of the starter according to the present application provides at least the following advantages: firstly, the exhaust assembly comprises a stopping part which prevents the exhaust assembly from being driven out of the mounting hole by gas in the electromagnetic switch along the gas discharging direction, and particularly, the exhaust assembly can be firmly fixed in a switch cover of the electromagnetic switch even if the gas pressure in the electromagnetic switch is overlarge in an abutting mode through a step part; secondly, the exhaust component of the electromagnetic switch comprises an air tightness interference fit part, and particularly, the exhaust component is fixed with the switch cover in an enhanced mode by using the elastic deformation mode of the convex teeth, and the air tightness sealing between the exhaust component and the switch cover is ensured; and thirdly, each hole section of the mounting hole formed on the switch cover and used for mounting the exhaust assembly is a unthreaded hole, so that the processing and the manufacturing are simple, and the cost is lower.
In conclusion, according to the electromagnetic switch of the application, the manufacture is simple, the cost is low, meanwhile, the fixation of the exhaust assembly in the switch cover is firm and reliable, and the phenomenon that the exhaust assembly slides out of the switch cover is guaranteed.
The foregoing merely illustrates a preferred embodiment in accordance with the principles of the invention and it will thus be appreciated by those skilled in the art that the present invention is not intended to be limited to the embodiments illustrated above and shown in the accompanying drawings. Various modifications and variations may occur to those skilled in the art, without departing from the spirit and scope of the invention, as defined by the following claims.
