Description

Technical Field

[0001] The utility model relates to the technical field of starters, and in particular to a high-efficiency waterproof switch structure of a starter. Background Art

[0002] A starter, also known as a motor, is a device used to start an internal combustion engine. Its main function is to convert the electrical energy of the battery into mechanical energy, drive the engine flywheel to rotate, and thus start the engine. Common starters include DC starters, gasoline starters, and compressed air starters. Among them, electric starters have become mainstream in the modern automotive field. They convert electrical energy into mechanical energy to automatically start the engine, greatly facilitating the driver's operation.

[0003] In the prior art, the switch structure of the starter is generally an electromagnetic structure. The electromagnetic structure has the advantages of fast response speed, high control accuracy, and high reliability. The switch structure is generally divided into a combination of a shell and a cover, and the two are mostly connected by a threaded connection. Although this method can quickly install the two, when used in some humid environments, it is inevitable that water vapor will enter the interior of the switch structure through the gap between the two, causing damage to the electronic components inside the switch structure, resulting in the switch structure being unusable. Utility Model Content

[0004] The purpose of the utility model is to provide an efficient and waterproof switch structure for a starter, which solves the problem that the switch structure is generally divided into a combination of a shell and a cover, and the two are mostly connected by a threaded connection. Although this method can quickly install the two, when used in some humid environments, it is inevitable that water vapor will enter the interior of the switch structure through the gap between the two, causing damage to the electronic components inside the switch structure, resulting in the problem of being unable to use the switch structure.

[0005] The utility model provides the following technical solution: a high-efficiency waterproof switch structure of a starter, comprising an electromagnetic switch body, an outer wall of the electromagnetic switch body is provided with a first clamp, the lower bottom end of the first clamp is fixedly connected to a second clamp, the lower bottom end of the second clamp is fixedly connected to a protective sleeve, the upper top of the first clamp is symmetrically threaded with a mounting screw, the mounting screw is located inside the protective sleeve, the end of the electromagnetic switch body is provided with a shell cover, and a sealing structure for reinforcing the seal is provided at the connection between the electromagnetic switch body and the shell cover.

[0006] By adopting the above scheme, the connection between the two clamps can limit the electromagnetic switch body during use. At this time, the electromagnetic switch body can be conveniently installed in a suitable position, and the protective sleeve is to protect the installation screw from damage and avoid rust due to water vapor. The installation screw is used to connect the clamp on the one hand and to install the electromagnetic switch body on the other hand.

[0007] As a preferred embodiment of the above technical solution, the sealing structure includes a sealant and a waterproof gasket bonded to the connection between the electromagnetic switch body and the shell cover, and the sealant uses a light-curing glue to seal the connection.

[0008] The model of the light-curing adhesive is TS391A, and the light-curing adhesive has excellent sealing and water resistance, which can effectively prevent water and moisture from penetrating into the main body of the electromagnetic switch, and can maintain its waterproof performance even when exposed to harsh environments such as humidity and temperature changes for a long time. This durability ensures that the switch can maintain good working condition during long-term use.

[0009] As a preferred embodiment of the above technical solution, the outer side wall of the shell cover is fixedly connected to a mounting plate, the outer side wall of the mounting plate is symmetrically fixedly connected to a second contact rod, and the outer side wall of the mounting plate is fixedly connected to a terminal at the interval between the two second contact rods.

[0010] With the above solution, the terminal is provided to facilitate connection with external wires, so that external power can provide corresponding support to the electromagnetic switch body through the wires and the terminal.

[0011] As a preferred embodiment of the above technical solution, a Z-shaped plate is provided on the outer wall of the shell cover at one side of the mounting upper plate, and the Z-shaped plate is located on the outer wall of the shell cover through bolts.

[0012] With the above scheme, the provision of the special-shaped plate and the circular plate is to facilitate the connection between the second contact rod and the shell cover, thereby increasing the corresponding stability. The Z-shaped plate is fixed to the outer wall of the shell cover by bolts, which can ensure that the contact rod is not easily displaced or fallen off when subjected to external forces or vibrations, thereby improving the stability and reliability of the entire switch structure.

[0014] By adopting the above scheme, the annular setting of the electromagnetic coil can generate an electromagnetic field more effectively. When the electromagnetic coil is energized, it can quickly generate a strong electromagnetic suction force, causing the moving iron core to move quickly, thereby driving the switch body to operate, realizing fast and accurate electromagnetic control. The static iron core is fixed inside the limit seat, so when the electromagnetic coil is working, the static iron core can attract the moving iron core to move and contact the end of the switch body, so that the switch body can be controlled.

[0015] As a preferred embodiment of the above technical solution, the outer side wall of the limit seat is fixedly connected with a contact plate, the end of the contact plate is fixedly connected with a pad, and the outer side wall of the pad is fixedly connected with a reset spring connected to the end of the mounting plate.

[0016] By adopting the above scheme, when the switch body enters into the interior of the driving switch, the static iron core and the limit seat will be compressed, and the reset spring will be in a compressed state. When the moving iron core in the switch body is no longer attracted, the reset spring can drive the switch body to automatically reset.

[0017] As a preferred embodiment of the above technical solution, the second contact rod extends to the inside of the shell cover, and the waterproof gasket is arranged on the contact surface between the inner top end of the shell cover and the second contact rod.

A waterproof gasket is also provided, and even if water vapor enters, it will be blocked by the waterproof gasket, further increasing the sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS

This fast curing feature makes the production and maintenance process of the switch more efficient, reducing production time and cost.

[0027] like Figure 2 , Figure 3 and Figure 4As shown, the outer wall of the shell cover 4 is fixedly connected to the mounting plate 41, and the outer wall of the mounting plate 41 is symmetrically fixedly connected to the second contact rod 44, and the outer wall of the mounting plate 41 is fixedly connected to the terminal 45 at the interval between the two second contact rods 44, so that the external wire can be quickly connected to generate power support for the electromagnetic switch body 1, and the outer wall of the shell cover 4 is provided with a Z-shaped plate 42 at one side of the mounting plate 41, and the Z-shaped plate 42 is located on the outer wall of the shell cover 4 through bolts, and the outer wall of the Z-shaped plate 42 is fixedly connected to the first contact rod 43, and the connection between the second contact rod 44 and the mounting plate 41 is fixedly connected to a special-shaped plate 441, and the connection between the other second contact rod 44 and the mounting plate 41 is fixedly connected to a circular plate 442, so as to increase the connectivity between the second contact rod 44 and the mounting plate 41.

[0028] like Figure 3 and Figure 4 As shown, an electromagnetic coil 13 is arranged in an annular shape inside the electromagnetic switch body 1, a switch body 11 is arranged at the inner end of the electromagnetic switch body 1, and a contact head 12 is arranged at the end of the switch body 11 so that it can be connected to an external power unit, thereby achieving the purpose of controlling the external power unit, and a moving iron core 19 is arranged at the end of the switch body 11, and a limiting seat 14 is arranged inside the electromagnetic switch body 1 at one side of the switch body 11, and a static iron core 15 is arranged inside the limiting seat 14, so that when the electromagnetic coil 13 works, the static iron core 15 generates suction, which can attract the moving iron core 19, and at this time, the switch body 11 can be driven to move, and a contact plate 18 is fixedly connected to the outer wall of the limiting seat 14, and a pad 16 is fixedly connected to the end of the contact plate 18, and a reset spring 17 connected to the end of the mounting plate 41 is fixedly connected to the outer wall of the pad 16, and the second contact rod 44 extends to the inside of the shell cover 4, and a waterproof gasket 31 is arranged on the contact surface between the inner top end of the shell cover 4 and the second contact rod 44, so as to further increase the sealing effect.

[0029] Working principle: When in use, connect the terminal 45 to the external wire, and then it can be used. Since the electromagnetic switch body 1 has been connected to the external wire, the electromagnetic coil 13 works and generates an electromagnetic field, and the static iron core 15 can attract or approach the static iron core 15 through the contact plate 18, and the static iron core 15 attracts the moving iron core 19 to drive the switch body 11 and the contact head 12 to contract, and control the external power mechanism connected to the contact head 12. At this time, the external power mechanism is in an open or closed state under the action of the electromagnetic switch body 1. When the electromagnetic coil 13 loses power support, it will no longer attract the moving iron core 19. At this time, the switch body 11 and the contact head 12 can be automatically reset under the drive of the reset spring 17, and because there is a large gap between the electromagnetic switch body 1 and the shell cover 4. A threaded connection method is mostly used. In some humid environments, it is easy for water vapor to enter the interior of the electromagnetic switch body 1 through the gap between the electromagnetic switch body 1 and the shell cover 4. In order to increase the sealing performance, a sealant 3 is arranged on the outside of the junction of the electromagnetic switch body 1 and the shell cover 4, and the sealant 3 is sealed with a photocurable glue. Under ultraviolet light, the photocurable glue can be quickly cured, thereby greatly shortening the production cycle. The cured glue layer has excellent weather resistance and chemical resistance, can maintain stable performance in various environments, and effectively achieves a waterproof effect to prevent water vapor from entering the interior of the electromagnetic switch body 1. A waterproof gasket 31 is also provided. Even if water vapor enters through the gap between the second contact rod 44 and the shell cover 4, it will be blocked by the waterproof gasket 31, further increasing the sealing effect.

[0030] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
