The utility model discloses in to enter the position of gas vent more hidden, guaranteed that water more is hard to enter into into gas vent, realize in the mounting shaft through the recess on the seal lip that gas can freely be passed in and out and water is unable gets into simultaneously to showing the waterproof performance who has improved ignition coil, and cancelled the pore structure among the current ignition coil, this has simplified spare part mould structure to a certain extent, thus reduce cost.
Description
Technical field
This utility model is relevant with ignition coil, particularly belongs to the waterproof sealing structure of a kind of ignition coil.
Background technology
Ignition coil is arranged on the cylinder head cover of electromotor, it includes ignition coil body 2 and high pressure extension bar 1, high pressure extension bar 1 includes high pressure extension bar main body and high-voltage connecting boom end, wherein high pressure extension bar main body cylindrically and extend in the mounting shaft 3 of electromotor, the diameter of high-voltage connecting boom end is more than the diameter of high pressure extension bar main body, for assembling, as shown in Figure 1 and Figure 2 with ignition coil body.
Owing to the operating temperature of electromotor changes between-40 degree are to 130 degree, therefore the gas in mounting shaft 3 can variation with temperature and constantly convergent-divergent, this just requires to leave the pore 4 that gas can be allowed to free in and out between the high pressure extension bar 1 of ignition coil and mounting shaft 3 to ensure the inside and outside pressure balanced of mounting shaft 3.But, owing to ignition coil needs between two electrodes of high-voltage transmission to spark plug, so for the insulation ensureing ignition coil, require that mounting shaft 3 and high pressure extension bar 1 seal to have prevented water from entering simultaneously.
At present; ignition coil product on existing market would generally be arranged labyrinth structure between ignition coil body 2 and high pressure extension bar 1 and be ultimately connected to pore 3; thus realize sealing water-proof function; as shown in Figure 3, Figure 4; having intake and exhaust groove 5 on the face that high-voltage connecting boom end and ignition coil body 2 phase are assembled, described labyrinth structure is to arrange some waterproof ribs 6 and one of them waterproof rib 6 with pore 3 at same position at high-voltage connecting boom end simultaneously.Although the passage of this pore 3 is through labyrinth structure, but owing to its intake and exhaust groove 5 remains exposed to the outside of mounting shaft 3, therefore when height/strong hydraulic pressure, the sealing waterproof ability ratio of ignition coil is relatively limited.Result of the test shows, this hermetic water-proof structure by the standard of IP4K, but often can cannot meet the requirement of IP9K.
Utility model content
Technical problem to be solved in the utility model is to provide the waterproof sealing structure of a kind of ignition coil, can improve the water resistance of ignition coil.
For solving above-mentioned technical problem, the waterproof sealing structure of the ignition coil that this utility model provides, wherein it is formed with some sealing lips on the high pressure extension bar of ignition coil, the groove having on each sealing lip at least one groove and adjacent seals lip is positioned at diverse location, the well head of the head parcel mounting shaft of described high pressure extension bar, and between a part for high-voltage connecting club head and mounting shaft well head, forming a porting, Open Side Down for described porting.
Wherein, described porting is the gap between the internal partial wall of high-voltage connecting club head and the top of mounting shaft well head and lateral wall.
In said structure, described porting is corresponding with at least one groove location of sealing lip.
Wherein, forming a gas flow passed in and out for gas in mounting shaft between described high pressure extension bar and mounting shaft, described gas flow is made up of the groove on the gap between high pressure extension bar and mounting shaft, each sealing lip and porting.
It is also preferred that the left have a groove on described each sealing lip, and between the groove on adjacent seals lip, angle is 180 degree.
The water resistance of ignition coil can be significantly improved by this utility model, to meet the highest classification of waterproof requirement of existing market application, and eliminating the air hole structure in existing ignition coil, this simplifies spare part mould structure to a certain extent, thus reduces cost.

Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
The waterproof sealing structure of ignition coil of the present utility model, as shown in Figure 5, some sealing lips 7 it are formed with on the high pressure extension bar 1 of ignition coil, the groove 8 having on each sealing lip 7 at least one groove 8 and adjacent seals lip 7 is positioned at diverse location, the well head of the head parcel mounting shaft 3 of high pressure extension bar 1, and between a part for high pressure extension bar 1 head and mounting shaft 3 well head, forming a porting 9, Open Side Down for described porting 9.
Wherein, porting 9 is the gap between the internal partial wall of high pressure extension bar 1 head and top and the lateral wall of mounting shaft 3 well head.
In the present embodiment, it is 180 degree that each sealing lip 7 has angle between a groove 8, and the groove 8 on adjacent seals lip 7, and porting 9 is corresponding with at least one groove 8 position of sealing lip 7, as shown in Figure 6.
Porting of the present utility model is arranged on high pressure extension bar 1 and coordinates the pithead position at place with mounting shaft 3, high-voltage connecting boom end coordinates with lateral wall and the top of well head, and it is opening down, compared with existing structure, the position of this porting is more hidden, thus ensure that water is more difficult to enter into porting.Simultaneously, a gas flow is formed between high pressure extension bar 1 and mounting shaft 3, this gas flow is made up of the groove 8 on the gap between high pressure extension bar 1 and mounting shaft 3, each sealing lip 7 and porting 9, so can ensure that the gas in mounting shaft 3 frees in and out, it is achieved the inside and outside pressure balanced of mounting shaft 3.
Meanwhile, this waterproof sealing structure is by arranging the labyrinth structure being made up of the groove of diverse location on sealing lip, thus in realizing mounting shaft, gas can be freed in and out by labyrinth channel and water cannot be introduced into.
The water resistance of ignition coil can be significantly improved by this utility model, to meet the highest classification of waterproof requirement of existing market application, and eliminating the air hole structure in existing ignition coil, this simplifies spare part mould structure to a certain extent, thus reduces cost.
Being described in detail this utility model above by specific embodiment, described embodiment is only preferred embodiment of the present utility model, and this utility model is not limited by it.In the case of without departing from this utility model principle, equivalent replacement that the distribution form of the labyrinth structure on sealing lip and the position etc. of porting are made by those skilled in the art and improvement, it is regarded as in the technology category that this utility model is protected.
