Description

Technical Field

[0001] The utility model relates to the technical field of water pump manufacturing, in particular to a waterproof chamber made of metal. Background Technique

[0002] At present, new energy vehicles can be seen everywhere. Whether it is pure electric or hybrid, a water pump is required to transport the coolant to various heat dissipation areas of the vehicle body. Once the water pump itself leaks, various fault alarms will appear in the vehicle itself.

[0003] For the existing waterproof chamber, for example, a motor waterproof structure disclosed in the utility model patent with the application number 201720980802.2, its main structure includes a housing, an end cover sleeved on the motor rotor shaft and fixedly connected to the housing, a bearing arranged between the end cover and the motor rotor shaft, and also includes a bearing outer cover, a water throwing disc and a cover plate. The bearing outer cover presses the bearing and is fixed on the end cover. A seal is arranged between the bearing outer cover and the motor rotor shaft. The water throwing disc is fixed on the motor rotor shaft and is arranged in clearance fit with the bearing outer cover. The cover plate is sleeved on the water throwing disc and fixedly connected to the end cover; during use, through the cooperation of the bearing outer cover, the seal, the water throwing disc and the cover plate, a waterproof and sealing structure is added outside the bearing and the end cover to prevent cooling water from directly entering the motor inner cavity from parts such as the bearing and the end cover.

[0004] However, in the traditional waterproof chamber, generally a heat dissipation block and plastic are placed at the bottom and injection molded together, and a sealing ring is used for sealing during assembly, and there are many factors affecting leakage. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a waterproof chamber made of metal, which is manufactured by integral stamping, not only completely realizes the separation of dry and wet, but also achieves the purpose of dissipating heat for the water pump.

[0006] A waterproof chamber made of metal of the utility model includes a housing; it also includes an edge, a protrusion and a rotating shaft. The edge is installed on the housing to facilitate the placement of the sealing ring. Four groups of protrusions are installed on the housing to enhance the fixing effect. The rotating shaft is installed on the housing, and the device is integrally stamped; by fixedly connecting this device with the water pump and installing the sealing ring inside the edge, the problem of coolant leakage into the dry chamber can be effectively avoided, and heat can be dissipated for the water pump.

[0007] Preferably, the housing material is SUS305 and the plate thickness is 1 mm; SUS305 is a high-quality stainless steel material with good corrosion resistance, high-temperature strength and good processing performance, which can not only adapt to the working environment inside the water pump, but also facilitate integral stamping.

[0008] Preferably, it further includes a groove formed on the edge; installing the sealing ring in the groove on the edge can not only fix the sealing ring, but also effectively avoid the problem of coolant leaking into the dry cavity.

[0009] Preferably, it further includes that there are four groups of the protrusions, and the four groups of protrusions are symmetrically arranged on the housing; stamping out four groups of symmetrical protrusions on the bottom of the housing can play a role in strengthening the fixation.

[0010] Preferably, it further includes that the diameter of the rotating shaft is 6 mm; by setting the rotating shaft, it is convenient for the housing to rotate following the motor and for the transmission of power.

[0011] Preferably, it further includes applying heat dissipation glue at the connection position between the bottom of the housing and the rotating shaft; closely attaching the water pump control board to this position, with the operation of the water pump and the flow of the coolant, the heat generated by the PCBA can be taken away, achieving the effect of dissipating heat for the whole water pump.

[0012] Compared with the prior art, the beneficial effect of the present utility model is that: fixedly connecting this device with the water pump and installing the sealing ring inside the edge can effectively avoid the problem of coolant leaking into the dry cavity and dissipate heat for the water pump.

[0018] For the convenience of understanding the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided so that the disclosure of the present utility model is more thorough and comprehensive.

[0019] Embodiment 1

[0020] A waterproof chamber made of metal according to the present utility model includes a housing 11; it further includes an edge 12, a protrusion 13 and a rotating shaft 14. The edge 12 is installed on the housing 11 to facilitate the placement of a sealing ring. Four groups of protrusions 13 are installed on the housing 11 to enhance the fixing effect. The rotating shaft 14 is installed on the housing 11, and the whole device is formed by stamping; the material of the housing 11 is SUS305 with a plate thickness of 1 mm; there is a groove on the edge 12; there are four groups of the protrusions 13, and the four groups of protrusions 13 are symmetrically arranged on the housing 11; the diameter of the rotating shaft 14 is 6 mm; when it works, first, install the sealing ring in the groove of the edge 12, which can not only fix the sealing ring, but also effectively avoid the problem of coolant leaking into the dry cavity. Four groups of symmetric protrusions 13 are stamped at the bottom of the housing 11, which can play a role in strengthening the fixation.
