Description
Technical Field
The utility model relates to an electronic pump technical field specifically is an electronic pump seal groove three-point positioning mechanism.
Background
After the automobile is started, heat dissipation components such as an engine and electronic control components can generate a large amount of heat, the generated heat must be timely discharged through a heat dissipation circulation system, the engine, the electronic control components and other heat dissipation components can normally work within a certain temperature range, and the electronic water pump is a power source for heat-conducting medium to flow circularly in the heat dissipation circulation system. In the current electronic water pump production technology, because the motor shape is comparatively complicated for the phenomenon that the sealing washer upwarped appears when sealed in the sealing washer, on the other hand, be clearance fit between current sealing washer and the seal groove, the sealing washer drops in the seal groove easily, makes behind the motor lid can not carry out good sealing with motor casing, influences the performance and the life of motor.
Disclosure of Invention
In order to solve the technical problem, the utility model provides an electronic water pump seal groove three-point positioning mechanism.
The utility model discloses the technical problem that will solve adopts following technical scheme to realize:
A three-point positioning mechanism for a sealing groove of an electronic water pump comprises a motor and a motor rear cover, wherein the motor and the motor rear cover are provided with the sealing groove which is formed by mutually laminating, a sealing ring is arranged in the sealing groove, the sealing ring is formed by sequentially connecting four long arc-shaped sections and four short arc-shaped sections end to end, and two ends of each long arc-shaped section 3a are provided with three-point positioning components;
the three-point positioning assembly comprises a first positioning salient point, a second positioning salient point and a third positioning salient point, wherein the first positioning salient point and the second positioning salient point are arranged on the inner side wall of the long arc-shaped section, and the third positioning salient point is arranged on the outer side wall of the long arc-shaped section.
As a further improvement of the present invention, the bending direction of the long arc-shaped section is outward along the radial direction, and the bending direction of the short arc-shaped section is inward along the radial direction.
as a further improvement, the top of a location bump, No. two location bumps, No. three location bumps and the inside wall of seal groove are to closing in order to be used for sealing washer and seal groove interference fit.
the utility model has the advantages that:
The utility model arranges three positioning salient points on the inner and outer side walls of the sealing ring, wherein, two positioning salient points are arranged on the inner side wall and one positioning salient point is arranged on the outer side wall, so that the sealing ring and the sealing groove can be in interference fit; the phenomenon that the sealing ring upwarps when sealed has not only been solved to current sealing washer, and the sealing ring is difficult for dropping from the seal groove moreover for lid and motor casing have good sealed behind the motor.
Drawings
the invention will be further described with reference to the following figures and examples:
Fig. 1 is an exploded view of the structure of the present invention;
Fig. 2 is a schematic structural view of a seal ring in the present invention;
Fig. 3 is an enlarged schematic view at I in fig. 2.
Detailed Description
in order to make the technical means, creation features, achievement purposes and effects of the present invention easy to understand, the present invention will be further explained with reference to the accompanying drawings and embodiments.
As shown in fig. 1 to 3, a three-point positioning mechanism for a sealing groove of an electronic water pump comprises a motor 1, a motor rear cover 2, and screws 5 for tightly connecting the motor 1 and the motor rear cover 2, wherein the motor 1 and the motor rear cover 2 are provided with sealing grooves 4 formed by mutually attaching, sealing rings 3 matched with the sealing grooves 4 are arranged in the sealing grooves 4, each sealing ring 3 is formed by sequentially connecting four long arc-shaped sections 3a and four short arc-shaped sections 3b end to end, the bending directions of the long arc-shaped sections 3a are outward along the radial direction, the bending directions of the short arc-shaped sections 3b are inward along the radial direction, two ends of each long arc-shaped section 3a are provided with three-point positioning assemblies, each three-point positioning assembly comprises a first positioning salient point 31, a second positioning salient point 32 and a third positioning salient point 33 arranged on the outer side wall of the long arc-shaped section 3a, no. one location bump 31, No. two location bumps 32, No. three location bumps 33 are triangle position and distribute, and the benefit of design like this lies in, has avoided the sealing washer to stick up toward one side easily, and then has solved because of the easy perk of sealing washer, has caused the problem of bad sealing. The top of a location bump 31, No. two location bumps 32, No. three location bumps 33 all supports with the inside wall of seal groove 4 and closes in order to be used for sealing washer 3 and 4 interference fit of seal groove to prevent that sealing washer 3 from dropping in the seal groove 4.
