Description
Technical Field
The present invention relates to a heating, ventilation and air conditioning (HVAC) housing, and more particularly to an assembly for connecting housing portions of a heating, ventilation and air conditioning (HVAC) housing.
Background
In general, a HVAC housing (hereinafter HVAC housing) may house different components of an HVAC system, such as an evaporator, a blower having different geometries and shapes. To accommodate these various components, the HVAC housing must be irregularly shaped. If the HVAC housing is formed as a single part, it is cumbersome to accommodate different components of the HVAC system having a wide variety of geometries. Thus, the HVAC housing needs to be formed as multiple housing sections and coupled together to obtain the final HVAC housing. Further, conventional coupling elements may be provided in multiple housing portions of the HVAC housing to enable the multiple housing portions to be coupled together. While coupling portions of the HVAC housing, the portions will be precisely guided over each other to achieve effective coupling and sealing of the housing portions of the HVAC housing. Such conventional coupling elements may include separate guide structures and locking structures capable of guiding and coupling multiple housing portions of the HVAC housing. However, such conventional coupling elements may perform a single function in one location, namely guiding the housing portions together at one location of the housing portions and coupling the housing portions together at a different location of the housing portions, which increases the assembly time of the HVAC housing. If there is not enough space in the coupling element, it is not possible to achieve the function of guiding and coupling the housing parts at the same location. In the event that the coupling between the housing portions is insufficient, the seal between the housing portions becomes ineffective, which results in leakage of fluid from the HVAC housing. In addition, leakage of air from the HVAC housing may result in ineffective performance of the HVAC system.
Accordingly, there is a need for a connection assembly to connect multiple housing sections of an HVAC housing. Further, there is a need for a connector that provides an effective seal between housing portions of an HVAC housing. Furthermore, there is a need for an HVAC housing with a connection means that provides guiding and coupling of the housing parts at the same location of the housing parts.

Detailed Description
The present invention relates to a HVAC system, hereinafter HVAC system, which may include an HVAC housing assembled from a plurality of individual housing portions. The plurality of individual housing portions of the HVAC housing may include guide pins and closure members formed on the housing portions of the HVAC housing adapted to couple the plurality of individual portions together. The closing member is provided with a cut-out portion which engages with the other housing portion when the guide pin formed in the housing portion and the closing member are connected to the other housing portion. Since the HVAC housing is formed of a plurality of housing portions, it is easy to accommodate different elements of HVAC having different geometries in the HVAC housing.
While the aspects described above and below that relate to coupling multiple housing portions using guide pins and closure members to form an HVAC housing may be implemented in any shape to couple multiple housing portions to form an HVAC housing, embodiments are described in the context of the following systems.
FIG. 1 illustrates a schematic diagram of an HVAC case 100 of an HVAC system formed of one or more independent case portions according to an embodiment of the invention. The HVAC housing 100 may be formed as multiple housing sections to obtain a shape as desired, and it may be any irregular shape. HVAC housing 100 must have any irregular shape to accommodate the different components, such as the evaporator, blower, and other heat exchangers. For simplicity and clarity, the HVAC housing 100 is illustrated with two housing portions coupled together to form the HVAC housing 100, however, the HVAC housing 100 is not limited to having two or more housing portions coupled together to form the HVAC housing 100. The HVAC housing 100 may include a first housing portion 102 and a second housing portion 104. The second housing portion 104 is detachably connected to the first housing portion 102. In other words, the HVAC housing 100 is formed by detachably connecting the first housing portion 102 with the second housing portion 104. For example, the detachable connection means, i.e. the first housing part 102 may be disconnected from the second housing part 104 in a non-destructive manner, and the first housing 102 may be connected again with the second housing 104 as before the disconnection. Furthermore, the connection and disconnection of the first housing part 102 and the second housing part 104 does not cause any damage to the housing parts. The first housing portion 102 may be connected to the second housing portion 104 in such a way that the first housing portion 102 may be sealed with the second housing portion 104 to avoid any fluid leakage at the connection between the first housing portion 102 and the second housing portion 104. The HVAC housing 100 may include one or more guide pins 106 and corresponding closure members 108 formed around the one or more guide pins 106. In an embodiment, one or more guide pins 106 and a closing member 108 are formed on the first housing portion 102 and adapted to protrude into the second housing portion 104 to enable a connection between the first housing portion 102 and the second housing portion 104. For brevity and clarity of the document, the HVAC housing 100 is further described with one guide pin surrounded by one closure member, however, it is not limited that the HVAC housing 100 has more than one guide pin and closure member.
Fig. 2A illustrates a perspective view of the first housing portion 102 and the second housing portion 104 of the HVAC housing 100 of fig. 1 in accordance with an embodiment of the present invention. The first housing portion 102 may include a guide pin 106 and a closure member 108. The guide pin 106 and the closing member 108 extend from the first housing part 102 and are adapted to protrude into the second housing part 104 when the first housing part 102 is connected to the second housing part 104. The closure member 108 is formed on the first housing portion 102 in such a way that the closure member 108 surrounds the guide pin 106. In an embodiment, the closure member 108 extends from the first housing portion 102 along with the guide pin 106. In another embodiment, the guide pin 106 and the closure member 108 extend perpendicularly from the first housing portion 102 of the HVAC housing 100. In an embodiment, the guide pin 106 and the closure member 108 are formed on a base 110 defined in the first housing portion 103. In other words, the guide pin 106 and the closure member 108 extend from a base 110 formed in the first housing portion 102.
The closure member 108 further includes one or more cut-out portions 112, the one or more cut-out portions 112 being adapted to be displaced towards the guide pin 106 when the closure member 108 is inserted into the second housing portion 104. In one embodiment, one or more cut-out portions 112 are formed by vertically cutting the closure member 108. In another embodiment, the closure member 108 is formed in a discontinuous circular shape with some openings, and one or more cut-out portions 112 are formed on the openings in the discontinuous circular shape closure member 108. In such an embodiment, the one or more cut-out portions 112 are formed as flexible walls disposed in the opening of the closure member 108. The closure member 108 further includes at least one locking element 114 formed on a perimeter of each of the one or more cutout portions 112, the locking element 114 being adapted to engage the second housing portion 104 when the closure member 108 is inserted into the second housing portion 104. For the sake of brevity and clarity of the document, the closure member 108 is illustrated with one cut-out portion having one locking element, however, there is no limitation in having more than one cut-out portion in the closure member 108 that includes more than one locking element. In an embodiment, the closure member 108 is shorter than the guide pin 106 such that the guide pin 106 is capable of guiding the first housing portion 102 into the second housing portion 104 and the closure member 108 is capable of locking the first housing portion 102 with the second housing portion 104.
The second housing portion 104 further comprises a receiving member 202, the receiving member 202 being adapted to receive the guide pin 106 together with the closing member 108 when the first housing portion 102 is connected to the second housing portion 104. The receiving member 202 may be formed on the second housing portion 104 in such a way that the receiving member 202 is in line with the guide pin 106 and the closure member 108 formed in the first housing portion 102. Since the receiving member 202 and the guide pin 106 together with the closing member 108 are in line with each other, the guide pin 106 together with the closing member 108 of the first housing portion 102 can be easily connected to the receiving member 202 of the second housing portion 104, thereby assembling the HVAC housing 100. Further, the locking element 114 formed on the cut-out portion 112 is adapted to engage with the receiving member 202 of the second housing portion 104 when the closure member 108 is coupled to the second housing portion 104.
Fig. 2B shows a schematic view of the guide pin 106, wherein the closure member 108 has one cut-out portion 112 formed in the first housing portion 102 of fig. 2A. The closing member 108 may be circular in shape, and the cutout portion 112 is formed on the circumference of the closing member 108. A locking element 114 is formed on the periphery of the cut-out portion 112, the cut-out portion 112 being adapted to engage with the second housing portion 104 when the closure member 108 is projected or inserted into the second housing portion 104. In an embodiment, the locking element 114 is a snap-fit assembly adapted to lock with the receiving member 202 of the second housing portion 104 when the closure member 108 is inserted into the second housing portion 104 together with the cut-out portion 112.
Fig. 2C shows a schematic view of a receiving member 202 formed on the second housing portion 104 of fig. 2A. The receiving member 202 comprises an aperture 204, the aperture 204 being adapted to receive the guide pin 106 of the first housing part 102 together with the closing member 108. When the closure member 108 protrudes into the aperture 204 provided in the receiving member 202 of the second housing portion 104, the cut-out portion 112 formed in the closure member 108 is displaced towards the guide pin 106. At the same time, the locking element 114 formed on the cut-out portion 112 engages with the periphery of the receiving member 202 of the second housing portion 104, thereby forming a rigid connection between the first housing portion 102 and the second housing portion 104. The receiving member 202 may include a cylindrical wall having a first end 206 and a second end 208. The guide pin 106, along with the closure member 108, passes through the first end 206 of the receiving member 202 to the second end 208 of the receiving member 202. As the guide pin 106 passes through the receiving member first end 206 along with the closure member 108, the cutout portion 112 and the locking element 114 are displaced radially towards the guide pin 106, thereby enabling easy insertion of the guide pin 106 along with the closure member 108 into the receiving member 202 of the second housing portion 104. When the locking element 114 has been fully inserted through the receiving member 202, the locking element 114 protrudes from the second end 208 out of the receiving member 202. The cut-out portion 112 is displaced outwardly from the guide pin 106, thereby enabling the locking element 114 to be coupled with the second end 208 of the receiving member 202 of the second housing portion 104.
Fig. 2D shows a cross-sectional view of the guide pin 106 surrounded by the closure member 108 formed on the first housing portion 102 of fig. 2A. The guide pin 106 has a cross section with three wings 212 extending radially from the center of the guide pin 106. In one embodiment, the three wings 212 of the guide pin 106 may be formed as three points. Further, when the closing member 108 is inserted into the receiving member 202 of the second housing portion 104, the cut-out portion 112 of the closing member 108 is displaced between two of the three wings 212 of the guide pin 106. The guide pin 106 further includes a reinforcing element 210 formed on the notched portion 112 on a side facing the guide pin 106 to provide reinforcement to the notched portion 112 when the notched portion 112 is displaced toward the guide pin 106.
Fig. 3A, 3B and 3C illustrate different views of an HVAC system 300 in which the HVAC housing 100 of fig. 1 is installed, according to an embodiment of the present invention. The HVAC system 300 can include an HVAC housing 100 adapted to house various elements, such as an evaporator, a blower, and flaps, etc. The HVAC housing 100 can include a third housing portion 302 adapted to be connected to the first and second housing portions 102, 104 at a connection point between the first housing portion 102 and the second housing portion 104. In an example, fig. 3A shows a cross-sectional view of the HVAC system 300 with the third housing portion 302 connected to the HVAC housing 100, and fig. 3B shows an exploded view of the HVAC system 300 depicting the first housing portion 102, the second housing portion 104, and the third housing portion 302. In this embodiment, the first housing portion 102 is connected to the second housing portion 104 in a straight line and the third housing portion 302 connects the first housing portion 102 and the second housing portion 104 vertically. The guide pin 106 and the closure member 108 of the first housing part 102 are connected with the receiving member 202 of the second housing part 104 by means of the third housing part 302. Further, the third housing portion 302 may include an aperture 304 formed on the third housing portion 302 in such a way that the aperture 304 is aligned with the receiving member 202 of the second housing portion 104 to receive the guide pin 106 and the closure member 108 of the first housing portion 102.
When the guide pin 106 and the closure member 108 of the first housing portion 102 pass through the aperture 304 and the receiving member 202, the first housing portion 102, the second housing portion 104, and the third housing portion 302 are connected together to form the HVAC housing 100. In one embodiment, the third housing portion 302 is connected between the receiving member 202 of the second housing portion 104 and the base 110 of the first housing portion 102, as shown in fig. 3A. Further, when the guide pin 106, along with the closure member 108, passes through the aperture 304 formed in the third housing portion 302 and the receiving member 202 of the second housing portion 104, the locking element 114 engages with the receiving member 202 of the second housing portion 104, thereby locking the first housing portion 102, the second housing portion 104, and the third housing portion 302 together. Furthermore, the guide pins 106 enable guiding the first housing part 102 into the second housing part 104 and the third housing part 302. At the same time, the closure member 108 enables the first housing portion 102 to be locked with the second and third housing portions 104, 302, as shown in fig. 3C. Fig. 3C is an assembled view of the first housing portion 102, wherein the second housing portion 104 and the third housing portion 302 form the HVAC housing 100. Since the guide pin 106 and the closure member 108 are capable of guiding and locking the housing portions of the HVAC housing 100, the packaging of the HVAC housing in the vehicle is improved and the housing portions of the HVAC housing are effectively sealed together.
Obviously, many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood that this invention may be practiced otherwise than as specifically described herein.
