TECHNICAL FIELD

[0001] The utility model relates to gearbox technical field, especially relate to a breather protector cover for gearbox controller. BACKGROUND

[0002] Gearbox controller is the control unit of automatic gearbox, and the gearbox controller is composed of shell, and the processor, signal processing circuit and power drive module etc. components arranged in the shell, and its shell is installed with breather, and the breather is used for the gas exchange between the inside and outside of gearbox controller, adjusts internal air pressure, removes internal exhaust gas etc. Function. Because the breather is located above the gearbox controller, when the gearbox controller is arranged horizontally, and the arrangement position is located in the outdoor shelter not strictly or is not equipped with the car hopper, the breather place can be rained in the rainy day and this place is very easy to accumulate water, and when the gearbox controller works, due to the temperature change, the inside and outside produce the risk of air pressure difference, and the accumulated water at the breather place enters the inside of the gearbox controller from the breather. SUMMARY

[0003] In view of the above defects, the utility model aims at providing a gearbox breather protector cover, which can effectively prevent the breather from raining or accumulating water, and has the protection effect of waterproofing and anti-pounding on the breather.

[0004] In order to achieve the above purpose, the technical scheme of the utility model is:

[0005] A gearbox breather protector cover is buckled on the shell of a gearbox controller, comprising a water shielding part above the breather, wherein the water shielding part is integrally connected with a downward bending part on the side of the edge of the shell of the gearbox controller, and a gas gap is left between the downward bending part and the shell of the gearbox controller for gas exchange of the breather.

[0006] The side of the water shielding part towards the breather is provided with an annular positioning protrusion.

[0007] The positioning protrusion is provided with a gas gap notch at the position corresponding to the gas gap.

[0008] The positioning protrusion is clamped in the inner side of the side wall of the breather mounting groove.

[0009] The water shielding part outside the positioning protrusion is provided with a recessed glue groove, and the glue groove is filled with glue for sealing and fixing the protector cover on the shell of the gearbox controller.

[0010] The glue groove is in U shape and is arranged on the three sides of the water shielding part not connected with the downward bending part.

[0011] The water-shielding part is a plane structure on the inner side of the positioning protrusion.

[0012] The water-shielding part is a plane structure on the inner side of the positioning protrusion.

[0013] After the above technical scheme is adopted, the gearbox breather protector cover has the following beneficial effects:

[0014] The gearbox breather protector cover is arranged above the breather, and is bent downward, so that the air gap opening for gas exchange is downward, which can prevent the breather from being drenched by rain and can prevent rainwater from flowing backward, thereby effectively preventing the breather from being drenched and waterlogged, eliminating the risk of water entering the gearbox controller, and preventing the breather from being damaged by external objects, thereby achieving the waterproof and anti-impact protection of the breather.

[0015] In summary, the gearbox breather protector cover solves the technical problems of rain drenching and waterlogging of the breather of the gearbox controller in the prior art, and can effectively prevent the breather from being drenched or waterlogged, thereby achieving the waterproof and anti-impact protection of the breather.

[0021] The utility model is further described below in combination with the drawings and examples.

[0022] The orientation referred to in the specification is the orientation shown in the drawings, which only represents a relative positional relationship and does not represent an absolute positional relationship.

[0023] As Figure 1 , Figure 2 and Figure 3 shown, a protective cover 20 of a gearbox breather is square in structure and buckled on a gearbox controller shell 10, and a breather 30 is installed in a breather installation groove 12 at a side edge of the gearbox controller shell 10. The protective cover 20 includes a water shielding part 22 buckled above the breather 30, the water shielding part 22 is connected with a downward bending part 24 at a side edge of the breather 30, the water shielding part 22 and the downward bending part 24 are in an integrated structure, and the downward bending part 24 and the gearbox controller shell 10 leave a gas gap 50 for gas exchange of the breather 30. The downward bending part 24 makes the opening of the gas gap 50 downward, thereby effectively avoiding rainwater from flowing backward and protecting the breather 30 without affecting the gas exchange of the breather 30.

[0024] As Figure 2 , Figure 3 and Figure 4 shown, an inner side of the water shielding part 22, i.e., a side surface facing the breather 30, is an inclined surface matched with the gearbox controller shell 10. The inner side of the water shielding part 22 is provided with an annular positioning protrusion 28, the positioning protrusion 28 is matched in shape and size with the breather installation groove 12, and when the protective cover 20 is buckled on the gearbox controller shell 10, the positioning protrusion 28 is just buckled in the inner side of the side wall of the breather installation groove 12, thereby playing a positioning role for the protective cover 20. In order to make the airflow flow smoothly, the water shielding part 22 at the inner side of the positioning protrusion 28 is preferably in a planar structure, and meanwhile, a gas gap gap 29 is provided at a position of the positioning protrusion 28 corresponding to the gas gap 50, thereby facilitating the flow of gas.

[0025] As Figure 2 , Figure 3 and Figure 4 shown, a recessed glue groove 26 is provided on the water shielding part 22 outside the positioning protrusion 28, the glue groove 26 is preferably in a U-shaped type and is arranged at three sides of the water shielding part 22 not connected with the downward bending part 24, and glue 40 is filled in the glue groove 26, the glue 40 is sealing fixing glue, used for sealing and fixing the protective cover 20 on the gearbox controller shell 10, thereby effectively preventing rainwater from seeping from a gap between the protective cover 20 and the gearbox controller shell 10, eliminating the probability of water accumulation at the breather 30, and further playing a waterproof role.

[0026] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the drawings, the assembling process of the gearbox breather protector cover is as follows:

[0027] First step: clean the gearbox controller shell 10 and the protective cover 20 with alcohol, and wait for the alcohol to evaporate completely;

[0028] Second step: squeeze the glue into the glue groove 26, and make the glue fill full and overflow, then quickly cover the protective cover 20 on the gearbox controller shell 10, at this time, the glue of three edges should overflow;

[0029] Third step: press the protective cover 20 with hand for more than five seconds to ensure that there is no looseness;

[0030] Fourth step: place the gearbox controller in the direction of the breather 30 upward, and solidify at room temperature for more than 24 hours;

[0031] Fifth step: after complete solidification, clean the redundant residual glue around the protective cover 20 with a blade to complete the assembling.

[0032] As described above, the gearbox breather protector cover can effectively prevent rain or water accumulation at the breather, and has the protection effects of waterproofing and anti-punching on the breather.

[0033] The utility model is not limited to the above specific implementation, and the ordinary skilled in the art can make various changes without creative labor based on the above concept, and all the changes fall within the protection scope of the utility model.
