Definitions

  • the invention relates to a housing and a compressor equipped with such a housing. It is aimed, in particular, at applications in the automotive field.
  • enclosures housing a printed circuit board are known, with edges conforming to the inner contour of a housing defined jointly by the body and lid of the enclosure. Furthermore, the enclosure's watertightness is maintained by a gasket interposed between the body and the lid.
  • a compressor housing is known to DE102015 116052 .
  • the invention aims to overcome at least in part the previous drawbacks and proposes for this purpose a housing, in particular a compressor housing, said housing comprising first and second parts jointly defining a first housing, said housing further comprising a plate, one or more supports for holding said plate and a sealing gasket, said plate and said support(s) being arranged in said first housing, said sealing gasket being located between said first and second parts, said sealing gasket comprising one or more protrusions directed towards the inside of the first housing and pressing on said plate at the level of a contour of said plate to apply said plate to said support(s).
  • the protrusions on the gasket help to secure the plate within the housing. This reduces the risk of vibration at the plate's free edges without requiring additional fasteners such as screws or rivets. Furthermore, the limited surface area of the protrusions on the plate's perimeter further enhances the secure fit.
  • the invention also relates to a compressor comprising a housing as described above.
  • the invention relates to a housing. Its applications include, for example, in a motor vehicle as a compressor for a refrigerant fluid in a vehicle temperature control system, such as for a vehicle passenger compartment, and/or for vehicle components, such as an electrical energy storage device, an electric motor, and/or an electronic control device for said electric motor.
  • a motor vehicle as a compressor for a refrigerant fluid in a vehicle temperature control system, such as for a vehicle passenger compartment, and/or for vehicle components, such as an electrical energy storage device, an electric motor, and/or an electronic control device for said electric motor.
  • the housing accommodates an electric motor and a compression system driven by said motor.
  • the said housing comprises first and second parts 2 and 4, which together define a first compartment, not visible in this figure.
  • the first part 2 forms the body of the housing and the second part 4 forms a lid of said housing.
  • the housing for example, the body, advantageously includes a second compartment 6 for housing the electric motor and/or the compression system, not shown.
  • the body further includes inlet/outlet tubes 7 for the refrigerant intended to enter the second compartment 6 at low pressure and exit it at high pressure.
  • the second compartment 6 is intended to be closed by another cover, not shown, of the housing.
  • said first piece 2 includes an edge 20 peripherally delimiting said first housing, marked 10 and this time visible, the cover having been removed in this figure.
  • the said housing further includes a plate 8.
  • Said plate 8 is disposed in said first housing 10.
  • Said plate 8 is formed, for example, of a printed circuit board bearing various electronic components used, in particular, for controlling the drive motor located in said second housing 6.
  • a base of the first housing 10 advantageously forms a partition separating the first and second housings 6, 10.
  • Said second housing 6 is preferably configured so that the refrigerant circulating in said second housing 6 is in contact with said partition which allows at least part of the heat released by said electronic components located in said first housing 10 to be evacuated.
  • the said housing further includes a sealing gasket 12, located between the said first and second parts 2, 4, to ensure a watertight closure of the said first housing 10.
  • the said gasket 12 includes, for example, a metal core coated at least partially with an elastomeric material.
  • said housing includes one or more supports 14 for retaining said plate 8.
  • the said retaining support(s) 14 are arranged in said first housing 10.
  • said sealing joint 12 comprises one or more protrusions 22, here two, directed towards the interior of the first housing 10.
  • said protrusion or protrusions 22 press on said plate 8 at the level of a contour 24 of said plate 8 to apply said plate 8 onto said retaining supports 14.
  • the retention of plate 8 is reinforced, which limits the risk of vibration of the free edges of plate 8 without requiring multiple specific plate fastening elements, such as screws or rivets. Furthermore, by pressing on the contour 24 of plate 8, the protrusions 22 present a limited surface area. Indeed, it is understood that the aforementioned support(s) 14 are located along the contour 24 of plate 8.
  • the contour 24 of the plate 8 is free over at least part of said contour 24, in particular at the level of said protrusions 22.
  • the contour 24 of the plate 8 is free over its entirety and/or fits a wall 28 of said first housing 10, with a slight play.
  • the said protrusions 22 bear on said plate 8 and said plate 8 bears on the support(s) 14 in respective support areas.
  • the bearing area(s) of plate 8 on the support(s) 14 and the bearing area(s) of the protrusions 22 on plate 8 are located directly above each other. Plate 8 is thus sandwiched between said protrusions 22 and the support(s) 14.
  • the housing includes one or more mounting brackets 14' for the plate 8.
  • the mounting bracket(s) 14' are located, in particular, along the contour 24 of the plate 8.

  • the plate 8 includes first openings 30 for the passage of the first fastening elements 26.
  • the support(s) 14, 14' are here linked to the first part 2, notably formed from the material of said part 2.
  • the support(s) 14, 14' include, for example, a pin 16, 16' having a vertex 18, 18' in contact with the plate 8.
  • the vertex 18 of the pin 16 of the support(s) 14 forms the bearing area of the plate 8 against the support(s).
  • the pin 18' of the mounting support(s) 14' includes first bores 32 cooperating with the first mounting elements 26.
  • the said mounting bracket(s) 14' comprise a pin and a nut, bearing against said pin. Said nut is in contact with said plate. In other words, said plate bears against said nut. Said nut cooperates with said plate fastening elements 8.
  • the said support bracket(s) 14 and the said fixing bracket(s) 14' are located at a distance from each other.
  • first and second pieces 2, 4 are fixed to each other by sandwiching said joint 12 but, except locally, not said plate 8 whose contour 24, as already said, remains preferentially free.
  • the said protrusions 22 include one or more bosses 34 for contact with said plate 8. Said bosses 34 facilitate the support of said plate 8 against the retaining support(s) 14.
