Description

Technical Field

[0001] The present invention relates to an air-conditioning system, and more particularly to an intake housing for an air-conditioning system and a method of manufacturing a housing component. Background Art

[0002] Motor vehicles are typically provided with an air-conditioning system to regulate the temperature of various parts of the vehicle. Such an air-conditioning system generally includes an intake housing formed by assembling a plurality of housing components with each other. The internal space of the intake housing forms a cavity, and the housing components assembled with each other can be sealed in different ways at the joints to prevent leakage at the joints of the housing components.

[0003] However, for some special installation situations of the air-conditioning system, such as when the intake housing is arranged in a harsh environment such as the engine compartment of a vehicle, the leakage occurring at the joints of the housing components may affect the normal operation of the electronic components of the vehicle air-conditioning system. For example, substances such as water vapor in the engine compartment may enter the intake housing and damage the electronic components.

[0004] Therefore, there is still a need for an intake housing with further improved sealing performance. Summary of the Invention

[0005] In view of the above problems, according to a first aspect of the present invention, there is provided an intake housing for an air-conditioning system, characterized in that the intake housing includes: a first housing, a second housing fixed to the first housing in a first direction, and a first seal is provided between the first housing and the second housing, and a third housing fixed to the first housing and the second housing in a second direction different from the first direction, wherein the third housing includes a second seal provided at its opening, and the second seal is pressed against the first seal.

[0006] The intake housing according to the present invention has at least the following effects: by pressing the first seal and the second seal against each other, a good sealing effect is ensured at the joint of the two seals, and thus a good sealing effect is ensured at the intersection of the three housing components, thereby significantly improving the sealing performance of the entire intake housing and increasing the waterproof level of the entire intake housing.

[0007] The intake housing according to the present invention may have one or more of the following features.

[0008] According to one embodiment, preferably, the third housing includes a third housing body, and the second seal is an accessory integral with the third housing body. The intake housing according to this embodiment has a further improved sealing effect at the opening of the third housing, and thus the intake housing has further improved sealing performance.

[0009] According to an embodiment, preferably, a first groove for accommodating a second seal is formed on the first housing, and a second groove for accommodating the second seal is formed on the second housing. The first groove and the second groove form an annular accommodation space, and the first seal at least partially enters the annular accommodation space. The intake housing according to this embodiment has an improved sealing effect at the opening of the third housing, and thus the intake housing has further improved sealing performance.

[0010] According to an embodiment, preferably, the first seal and the second seal cross each other at the pressing position, and the second seal has a recess to at least partially receive the first seal. In the intake housing according to this embodiment, the contact sealing area formed by the first seal and the second seal at the intersecting position is increased, thereby further improving the sealing effect of the first seal and the second seal at the intersecting position.

[0011] According to an embodiment, preferably, the second seal has an embedding tooth, and the embedding tooth embeds into the main body of the third housing to define an embedding section. In the intake housing according to this embodiment, the second seal and the main body of the third housing can be more firmly combined to improve the sealing performance.

[0012] According to an embodiment, preferably, at the opening of the third housing, the second seal and the main body of the third housing form a V-shaped edge, wherein the outer branch of the V-shaped edge is constituted by the second seal, and the inner branch of the V-shaped edge is constituted by the main body of the third housing. In the intake housing according to this embodiment, the sealing effect of the second seal at the opening of the third housing and the mechanical strength near the opening of the third housing are jointly improved.

[0013] According to an embodiment, preferably, the second seal has a support rib facing the main body of the third housing. In the intake housing according to this embodiment, the shape of the second seal and its position relative to the main body of the third housing can be better maintained, thereby better ensuring the sealing performance.

[0014] According to an embodiment, preferably, the main body of the third housing has a fastening component, and the embedding section is arranged near the fastening component. In the intake housing according to this embodiment, by arranging the embedding section near the fastening component which is a key stress point, it is ensured that the second seal near the fastening component can be firmly combined with the main body of the third housing.

[0015] According to an embodiment, preferably, one of the first housing and the second housing is formed with a receiving groove for receiving the first seal. The receiving groove extends along the joint portion of the first housing and the second housing and has a first end and a second end. Guide posts are provided near the first end and / or the second end so that the end of the first seal deflects towards the outside of the intake housing. In the intake housing according to this embodiment, the end of the first seal deflects towards the outside of the intake housing, so that the assembler can conveniently confirm or check that the first seal has been installed on the first housing or the second housing to prevent missing installation and ensure the sealing effect at the same time.

[0016] According to an embodiment, preferably, the other of the first housing and the second housing is provided with a protrusion protruding towards the opposing housing. The protrusion is provided near the guide post and presses against the end of the first seal after deflection. In the intake housing according to this embodiment, the end of the first seal can be firmly held, thus helping to ensure the sealing effect.

[0017] According to a second aspect of the present invention, a method of manufacturing a housing component is provided. The housing component is the third housing of any of the foregoing intake housings. The method includes: manufacturing a housing component body of the housing component; placing the housing component body in a cavity formed by a first mold and a second mold so that a seal molding space corresponding to the second seal is left in the cavity; injecting a seal material into the seal molding space to form the second seal.

[0018] In the housing component (third housing) manufactured by this method, the third housing body and the second seal are completely shape-fitted to each other and adhered to each other, so that the manufactured intake housing has significantly improved sealing performance and the manufacturing process is relatively simple.

[0019] According to an embodiment, preferably, the seal material is a soft rubber and the housing component body is made of a hard rubber. The housing component (third housing) manufactured by this method has a relatively hard housing component body and a relatively soft seal, thereby ensuring the strength of the third housing and its sealing performance after being assembled with other housing components at the same time.

[0081] Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings understood by those of ordinary skill in the art to which the present invention pertains. The "first", "second", and similar terms used in the specification and claims of this invention patent do not denote any order, quantity, or importance, but are merely used to distinguish different components. In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "left", "right", "top", "bottom", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0082] The present invention will be described in detail below by way of describing exemplary embodiments.

[0083] Figure 1 and Figure 2 respectively show a perspective view and an exploded view of the intake housing 100 according to an embodiment of the present invention. As Figure 1 and Figure 2 shown, the intake housing 100 includes a first housing 1, a second housing 2, and a third housing 3, wherein the second housing 2 is fixed to the first housing 1 along a first direction (such as Figure 1 , 2 the vertically downward direction in), and the third housing 3 is fixed to the mutually fixed first housing 1 and second housing 2 along a direction different from the first direction (such as Figure 1 , 2 the substantially horizontally leftward direction in).

[0084] As Figure 2 further shown, a first seal 4 is provided between the first housing 1 and the second housing 2. The first seal 4 can be a sealing strip, which is configured to be arranged in a receiving groove 110 at the opening edge of the first housing 1. Specifically, as Figure 2As shown, the upward-facing opening of the first housing 1 is configured to engage with the downward-facing opening of the second housing 2. A section of the opening edge of the first housing 1 is configured to be covered by the third housing 3 from the right side, and the section of the opening edge of the first housing 1 that is not covered by the third housing 3 (i.e., the section exposed to the outside of the intake housing) is provided as a continuous receiving groove 110. Thus, the receiving groove 110 has a first end 111 and a second end 112, and a first seal 4 in the form of a sealing strip is arranged in the receiving groove 110.

[0085] On the other hand, the section of the opening edge of the second housing 2 corresponding to the receiving groove 110 of the first housing 1 is configured as a raised edge section 210. When the first housing 1 and the second housing 2 are engaged with each other and the first seal 4 has been arranged in the receiving groove 110, the raised edge section 210 at least partially enters the receiving groove 110 and presses the first seal 4, thereby sealing the intake housing 100 at the opening edge section corresponding to the receiving groove 110.

[0086] Further referring to Figures 1 to 3 , as described above, the third housing 3 is fixed to the first housing 1 and the second housing 2 that are fixed to each other. As Figure 2 and Figure 3 shown, a first groove 120 is provided at a position on the first housing 1 for engaging a part of the opening edge 301 of the third housing 3, and a second groove 220 is provided at a position on the second housing 2 for engaging another part of the opening edge 301 of the third housing 3. When the first housing 1 and the second housing 2 are fixed to each other, the first groove 120 and the second groove 220 form an annular receiving space 125. In other words, the annular receiving space 125 is for receiving the opening edge 301 of the third housing 3.

[0087] As Figure 2 shown, the third housing 3 includes a third housing body 310 and a second seal 320. The second seal 320 is annular and is arranged around the entire opening edge 301 of the third housing 3. In this embodiment of the present invention, the second seal 320 is an accessory integral with the third housing body 310 to be firmly attached to the third housing body 310. When the third housing 3 is fixed to the first housing 1 and the second housing 2, the second seal 320 and the opening edge 311 of the third housing body 310 enter the annular receiving space 125 together. The second seal 320 is pressed in the annular receiving space 125, and this pressing makes the third housing 3 at least substantially sealed relative to the outside.

[0088] According to the present invention, when the respective housing components (i.e., the first housing 1, the second housing 2, and the third housing 3) are hermetically assembled with each other through the first seal 4 and the second seal 320, the first seal 4 and the second seal 320 are pressed against each other. In this embodiment of the present invention, the first seal 4 and the second seal 320 are pressed against each other near the first end 111 and the second end 112 of the receiving groove, respectively. Thus, the first housing 1, the second housing 2, and the third housing 3 also have good sealing at the intersection. Therefore, the entire intake housing 100 is completely sealed with respect to the outside world, and the intake housing 100 also has significantly improved sealing performance compared to the existing intake housing.

[0089] Next, with reference to Figures 4A - 8D , the related structure of the intake housing 100 will be further described.

[0090] Figure 4A and 4B respectively show a top view and a perspective view of the first housing 1 of the intake housing 100 according to an embodiment of the present invention, wherein the first seal 4 is installed in the receiving groove 110. As Figure 4A and Figure 4B shown, the ends of both ends of the first seal 4 also extend beyond the first end 111 and the second end 112 of the receiving groove, respectively, and deflect outward. On the other hand, also refer to Figure 5A and 5B , the first end 111 of the receiving groove is also connected to the first end 121 of the first groove 120, and the second end 112 of the receiving groove is connected to the second end 122 of the first groove 120, so that when the first seal 4 is arranged in the receiving groove 110, the first seal 4 at least partially enters the first groove 120, that is, at least partially enters the annular accommodation space 125.

[0091] As Figure 5A and Figure 5B specifically shown, the space near the bottom of the first end 111 of the receiving groove partially intersects with the space near the bottom of the first end 121 of the first groove 120, thereby forming a first adjacent portion 130. Similarly, the space near the bottom of the second end 112 of the receiving groove partially abuts against the space near the bottom of the second end 122 of the first groove 120, thereby forming a second adjacent portion 140. By allowing the first seal 4 to enter the annular accommodation space 125 at the first adjacent portion 130 and the second adjacent portion 140 respectively, the first seal 4 and the second seal 320 assembled with each other can be pressed against each other, so as to completely seal the entire intake housing 100 with respect to the outside world. Also refer to Figure 6 for a perspective view showing only the assembly of the first seal 4 and the second seal 320 with each other.

[0092] Furthermore, with reference to Figure 7A, which shows a partial front view of the first housing 1, shows the first end 111 of the receiving groove, and shows the first seal 4 and the second seal 320 pressed against each other, wherein the first seal 4 partially enters the annular receiving space 125.

[0093] Figure 7A Also shown is the first guide post 132 provided on the first housing 1 near the first end 111 of the receiving groove. See also Figure 7B . The first guide post 132 restricts the specific extending direction of the end of the first seal 4 extending out from the first end 111 of the receiving groove, causing the end to deflect towards the outside of the intake housing 100. Thus, the assembler can easily confirm or check whether the first seal 4 is installed between the first housing 1 and the second housing 2 that have been joined or assembled with each other, thereby preventing missing installation and at the same time ensuring the sealing performance of the first seal 4. Similarly, the first housing 1 may be provided with a second guide post 142 near the second end 112 of the receiving groove. The second guide post 142 restricts the specific extending direction of the end of the first seal 4 extending out from the second end 112 of the receiving groove, causing the end to deflect towards the outside of the intake housing 100.

[0094] Figure 7B Also shown is the corresponding part of the second housing 2, showing the first protrusion 232 provided on the second housing 2 protruding towards the first housing 1. The first protrusion 232 is provided near the first guide post 132 and presses against the deflected end of the first seal 4 to further fix the first seal 4 and ensure the extending direction of the end. Similarly, the second housing 2 may also be provided with a second protrusion 242 protruding towards the first housing 1. The second protrusion 242 is provided near the second guide post 142 and presses against the deflected end of the first seal 4. Alternatively, guide components and protrusion components with other structures may be provided at the first end 111 and / or the second end 112 of the receiving groove to deflect the end of the first seal 4 towards the outside of the intake housing.

[0095] Figure 8A and 8B respectively show partial perspective views of the second seal 320 according to an embodiment of the present invention provided near the first end 111 and the second end 112 of the receiving groove. Figure 8C and 8D respectively show partial perspective views of the first seal 4 and the second seal 320 in the assembled position according to an embodiment of the present invention provided near the first end 111 and the second end 112 of the receiving groove. As Figures 8A - 8DAs shown, the second seal 320 has recesses 321 near the first end 111 of the receiving groove to at least partially receive the first seal 4, and the second seal 320 presses against and crosses the first seal 4 at the recess 321. The second seal 320 has recesses 322 near the second end 112 of the receiving groove to at least partially receive the first seal 4, and the second seal 320 presses against and crosses the first seal 4 at the recess 322. Thus, when the first seal 4 and the second seal 320 are jointly assembled in the intake housing 100, the contact area at the intersection of the first seal 4 and the second seal 320 increases, thereby improving the sealing effect at the intersection, and at the same time preventing the first seal 4 and the second seal 320 from being difficult to install or the seal being broken due to excessive pressure between them.

[0096] The intake housing 100 having the foregoing structure can be assembled through the following steps: First, the first housing 1 is fixed with its opening facing upward, and the first seal 4 is placed in the receiving groove 110. The first seal 4 is in a natural stretched state in the receiving groove 110, and the orientations of the two end heads of the first seal 4 located outside both ends of the receiving groove 110 are approximately fixed by the guide posts 132 and 142; then, the second housing 2 is placed above the first housing 1, and the protruding edge section 210 of the second housing 2 at least partially enters the receiving groove 110 to abut against the first seal 4, and then the second housing 2 is positioned and fixed to the first housing 1 (for example, by positioning pins and screws respectively), and this step presses the first seal 4; finally, the third housing 3 is installed on the first housing 1 and the second housing 2 fixed to each other. The opening edge 301 of the third housing 3 together with the second seal 320 at least partially enters the annular receiving space 125, and then the third housing 3 is fixed to the first housing 1 and the second housing 2 fixed to each other by screws, for example, and this step presses the second seal 320.

[0097] Next, with reference to Figures 9A - 11 , some advantageous specific structures of the third housing 3 will be described, especially the structure of the cooperation between the second seal 320 and the third housing body 310.

[0098] Figure 9A and Figure 9B respectively show the third housing 3 without the second seal 320 and with the seal 320. As described above, the second seal 320 is disposed around the entire opening edge 301 of the third housing 3. Also refer to Figure 10A and Figure 10B, the second seal 320 has one or more embedding teeth 323 in some of its segments, thereby defining an embedding segment 324. These embedding teeth 323 are embedded in corresponding one or more grooves 313 of the opening edge 311 of the third housing body 310, so that the second seal 320 and the third housing body 310 are fixed to each other more firmly.

[0099] In Figure 9A and 9B , each embedding segment 324 is disposed near a fastening member 330 of the third housing 3 for fixing to the first housing 1 or the second housing 2. Since the portion of the third housing 3 near the fastening member 330 undergoes greater deformation and pressure, disposing the embedding segment 324 near the fastening member 330 particularly effectively prevents the second seal 320 from detaching from the third housing body 310 near the fastening member 330. However, the embedding segment 324 can also be disposed at other positions on the opening edge 301 of the third housing 3.

[0100] Further referring to Figure 10A and Figure 10B , which respectively show partial views of a cross-section of the third housing 3. In the cross-section as shown in Figure 10A and Figure 10B , the second seal 320 and the third housing body 310 form a V-shaped edge. The outer branch 328 of the V-shaped edge is constituted by the second seal 320, and the inner branch 318 of the V-shaped edge is constituted by the third housing body 310. Compared with the prior art arrangement of providing a separate sealing ring at the opening edge of the housing, the above structure of the present invention enables the opening edge 301 of the third housing 3 to have both high structural strength and good sealing performance near its top. Such a V-shaped edge structure can extend to the aforementioned embedding segment 324, where a part of the inner branch 318 of the V-shaped edge is constituted by the material of the second seal 320 to ensure the firm local bonding between the second seal 320 and the third housing body 310 and the overall sealing effect.

[0101] Figure 11 shows the side of the third housing 3 opposite to its opening, specifically showing the support ribs 326 of the second seal 320. Also referring to Figure 10A , the support ribs 326 extend towards the third housing body 310. In Figure 10A and Figure 11 , the support ribs 326 extend from the second seal 320 towards the outer surface 340 of the third housing body 310 and are supported between the second seal 320 and the outer surface 340, thereby further supporting the bonding between the second seal 320 and the third housing body 310 and the sealing effect of the second seal 320.

[0102] As Figures 9A - 11The third housing 3 shown can be manufactured by the manufacturing method shown in FIGS. 12 - 16, and a good form fit and bonding effect between the second seal 320 and the third housing body 310 can be obtained. The third housing 3 in the following text is also referred to as the housing component 3, and the following manufacturing method is applicable to the manufacture of housing components that require such sealing.

[0103] In the method for manufacturing the housing component 3 according to an embodiment of the present invention, Figure 12A and Figure 12B the first mold 5 and the second mold 6 shown respectively are used to manufacture the housing component 3. Figures 13 - 16 Some steps of the method are shown.

[0104] In this method, first, the housing component body 310 of the housing component 3 is manufactured, and then the housing component body 310 is placed in the cavity formed by the first mold 5 and the second mold 6, as Figures 13 - 15 shown, and a seal molding space corresponding to the second seal 320 is left in the cavity. Specifically, as Figure 12A and Figure 12B shown, the cavity surfaces of the first mold 5 and the second mold 6 basically correspond to the outer surface and the inner surface of the housing component body 310, and only partial seal molding spaces 505, 605 are left at the corresponding positions of the second seal 320 respectively. After the housing component body 310 is placed in the cavity and the first mold 5 and the second mold 6 are closed with each other, the partial seal molding spaces 505, 605 together form a seal molding space corresponding to the second seal.

[0105] Next, as Figure 16 shown, a seal material is injected into the seal molding space (for example, the seal material is injected through the injection hole 501 shown in Figure 12A shown) to form the second seal 320. After the seal material is cured, the formed second seal 320 and the housing component body 310 are bonded together as a whole. After that, the first mold 5 and the second mold 6 can be separated from each other to take out the integrated housing component 3.

[0106] In an embodiment according to the present invention, the housing component body 310 is made of hard glue, while the second seal 320 is made of soft glue, thereby ensuring the mechanical strength of the housing component 3 and the sealing effect of its opening edge.
