Description

Technical Field

[0001] The utility model relates to the technical field of transmission housing processing, and particularly relates to a hydrophobic device for a new energy transmission housing. Background Art

[0002] With the popularization of new energy vehicles, as one of the core components of automobiles, the performance and reliability of the transmission are crucial for the operation of the whole vehicle. During vehicle driving, especially in the case of wading through water, water is likely to accumulate in the transmission housing, resulting in internal components being affected by moisture, corroded, and even causing failures. Therefore, designing an effective hydrophobic device for the transmission housing is of great significance for improving the reliability and safety of new energy vehicles.

[0003] The Chinese utility model with the publication number CN211371220U proposes a new type of hydrophobic device for a transmission housing: including a sphere, a bracket, and a housing mounting boss. The housing mounting boss includes a hydrophobic hole, a boss conical surface, and a snap ring groove. A bracket is arranged inside the housing mounting boss, and a sphere is arranged inside the bracket. Anti - detachment buckles are arranged at the groove positions on the surface of the bracket. The housing mounting boss is cast on the transmission housing, and the number of anti - detachment buckles is several groups. In the hydrophobic device for the transmission housing of the utility model when the vehicle wades through water, the sphere floats upward by the buoyancy of water and contacts the conical surface of the housing mounting boss to form a linear seal, which can effectively prevent external water from flowing back and effectively prevent the failure of the components with poor waterproof performance inside the transmission.

[0004] However, the existing technology still has deficiencies:

[0005] The sealing structure formed only by the buoyancy of the sphere rising is not very stable. When the housing is being lifted from the water body and has not completely separated from the water body, the sphere will sink due to the change in buoyancy, affecting the sealing performance of the device. Summary of the Utility Model

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a hydrophobic device for a new energy transmission housing, which solves the problem that in the prior art, the sealing structure formed only by the buoyancy of the sphere rising is not very stable. When the housing is being lifted from the water body and has not completely separated from the water body, the sphere will sink due to the change in buoyancy, affecting the sealing performance of the device.

[0007] To achieve the above object, the utility model provides a hydrophobic device for a new energy transmission housing, including a bracket. A plurality of drainage holes are opened at the bottom of the bracket. A sphere is arranged inside the bracket. The density of the sphere is less than that of water. A base is fixedly installed inside the bracket. A pair of limit holes are opened on the base. The limit holes are symmetrically arranged on both sides of the sphere. A guide rod is slidably connected inside the limit hole. A magnet ring is fixedly installed on the guide rod. One end of the guide rod is fixedly installed with a limit rod.

[0008] As a further solution of the present invention: a limiting ring is fixedly mounted on the bracket, and a plurality of buckles are fixedly mounted on the bracket.

[0009] As a further solution of the present invention: a limit seat is provided on the base, and the position of the limit seat corresponds to the position of the sphere.

[0010] As a further solution of the present invention: a plurality of through holes are provided in the limit seat.

[0011] As a further solution of the present invention: the magnet ring is semicircular, and a pair of the magnet rings attract each other to form a circular ring.

[0012] As a further solution of the present invention: the ring is arranged on the outer ring of the sphere and close to the upper end of the sphere.

[0013] As a further solution of the present invention: the limiting rod is fixedly mounted on an end of the guide rod away from the limiting ring.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. A magnet ring is arranged on the outer ring of the sphere, a circle of iron foil is fixedly installed on the sphere, a drainage hole is opened at the bottom of the bracket, and a plurality of through holes are opened in the limit seat; a pair of limit holes are opened on the base, and the limit holes are symmetrically arranged on both sides of the sphere. A guide rod is slidably connected in the limit hole, and a magnet ring is fixedly installed on the guide rod. The magnet ring is semicircular, and a pair of magnet rings attract each other to form a circular ring. The circular ring is arranged on the outer ring of the sphere and close to the upper end of the sphere. A limit rod is fixedly installed on the end of the guide rod away from the limit ring. Pulling the limit rod can drive the pair of magnet rings away from each other. When water accumulates inside the gearbox, the sphere will float up under the action of buoyancy, press against the limit ring, and block the limit ring. The hole on the ring prevents water from continuing to enter the gearbox. During the rising process of the sphere, the iron foil is driven up by the sphere. When the iron foil rises and approaches the magnet ring, it is attracted by the magnet ring and accelerates the rising speed of the sphere. After attraction, the sphere can be limited to keep the sphere and the limit ring against each other. When the gearbox is taken out of the water or drained, the sphere can maintain the contact state with the limit ring. When the gearbox is out of the water, the pair of limit rods are pulled toward each other, driving the pair of magnet rings away from each other, thereby releasing the attraction of the iron foil. The sphere recovers under the action of gravity and falls into the limit seat. When the sphere is away from the limit seat, the through hole on the limit seat is exposed. Through the cooperation of the drainage hole, the limit hole and the through hole, the accumulated water in the device can be discharged.

[0016] 2. By providing a limit seat on the base that matches the sphere and cooperating with the guide rod, the stability of the sphere's movement during the rising and falling process can be maintained. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] As Figures 1-3 shown, a hydrophobic device for a new energy transmission case includes a bracket 1, a limit ring 4 is fixedly installed on the bracket 1, and a plurality of buckles 2 are fixedly installed on the bracket 1. The purpose of the above settings is to install the device on the transmission. The overall connection between the device and the transmission is realized by the buckle 2 being clamped with the snap ring groove in the installation boss of the transmission. The limit ring 4 corresponds to the hydrophobic hole on the transmission installation boss, and the transmission is connected to the outside through the hole on the limit ring 4;

[0023] As an implementation mode in this embodiment, a sphere 3 is arranged inside the bracket 1. The density of the sphere 3 is less than that of water, and it floats when encountering water. A circle of iron foil 9 is fixedly installed on the sphere 3. A base 6 is fixedly installed inside the bracket 1. A limit seat 12 is opened on the base 6. The position of the limit seat 12 corresponds to that of the sphere 3, which plays a limiting role for the sphere 3. A number of through holes 13 are opened inside the limit seat 12; a pair of limit holes 5 are opened on the base 6. The limit holes 5 are symmetrically arranged on both sides of the sphere 3. A guide rod 10 is slidably connected inside the limit holes 5. A magnet ring 11 is fixedly installed on the guide rod 10. The magnet ring 11 is semicircular. A pair of magnet rings 11 attract each other to form a ring. The ring is arranged on the outer circle of the sphere 3 and close to the upper end of the sphere 3. A limit rod 8 is fixedly installed at one end of the guide rod 10 away from the limit ring 4. Pulling the limit rod 8 can drive a pair of magnet rings 11 to move away from each other. The purpose of the above settings is that when there is accumulated water inside the gearbox, the sphere 3 floats upward under the action of buoyancy, abuts against the limit ring 4, blocks the holes on the limit ring 4, and prevents the gearbox from continuing to intake water. During the rising process of the sphere 3, the iron foil 9 is driven to rise. When the iron foil 9 rises close to the magnet ring 11, it is attracted by the magnet ring 11 to accelerate the rising speed of the sphere 3. After being attracted, the sphere 3 can be limited, and the sphere 3 is kept in contact with the limit ring 4. When the gearbox is taken out of the water body or drained, the sphere 3 can maintain the contact state with the limit ring 4. When the gearbox is separated from the water body, pull a pair of limit rods 8 in opposite directions to drive a pair of magnet rings 11 to move away from each other, thereby releasing the attraction to the iron foil 9, and the sphere 3 returns to its original position under the action of gravity and falls into the limit seat 12.

[0024] As an implementation mode in this embodiment, a number of drain holes 7 are opened at the bottom of the bracket 1. Cooperating with the limit holes 5 and the through holes 13, the accumulated water inside the device can be drained.

[0025] Working principle:

[0026] Install the device on the gearbox. The overall device is fixedly connected to the gearbox by clamping the buckle 2 with the snap ring groove inside the installation boss of the gearbox. The limit ring 4 corresponds to the hydrophobic hole on the installation boss of the gearbox. The gearbox is communicated with the outside through the holes on the limit ring 4; when there is accumulated water inside the gearbox, the sphere 3 floats upward under the action of buoyancy, abuts against the limit ring 4, blocks the holes on the limit ring 4, and prevents the gearbox from continuing to intake water. During the rising process of the sphere 3, the iron foil 9 is driven to rise. When the iron foil 9 rises close to the magnet ring 11, it is attracted by the magnet ring 11 to accelerate the rising speed of the sphere 3. After being attracted, the sphere 3 can be limited, and the sphere 3 is kept in contact with the limit ring 4. When the gearbox is taken out of the water body or drained, the sphere 3 can maintain the contact state with the limit ring 4. When the gearbox is separated from the water body, pull a pair of limit rods 8 in opposite directions to drive a pair of magnet rings 11 to move away from each other, thereby releasing the attraction to the iron foil 9, and the sphere 3 returns to its original position under the action of gravity and falls into the limit seat 12.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0028] The above has described in detail one embodiment of the present utility model, but the content described is only the preferred embodiment of the present utility model and cannot be considered as used to limit the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of the application of the present utility model should still fall within the scope covered by the patent of the present utility model.
