Description

Intake housing and method for producing a housing component Technical Field

[0001] The present invention relates to an air-conditioning system, in particular to an air intake housing for the air-conditioning system, and a method for manufacturing housing components. Background Art

[0002] Motor vehicles are often equipped with air conditioning systems to regulate the temperature of various vehicle components. These systems typically include an air intake housing formed by assembling multiple housing components. The interior of the air intake housing forms a cavity, and the joints between the assembled housing components can be sealed in various ways to prevent leakage.

[0003] However, in some unique air conditioning system installations, such as in harsh environments like the vehicle's engine compartment, leaks at the interface between housing components can affect the proper functioning of the vehicle's air conditioning system's electronic components. For example, moisture and other substances in the engine compartment can enter the air intake housing and damage the electronic components.

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

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

[0006] The air 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 junction of the two seals, thereby ensuring a good sealing effect at the intersection of the three housing components, thereby significantly improving the sealing performance of the entire air intake housing and improving the waterproof level of the entire air intake housing.

[0007] The air 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 sealing member is an accessory integral with the third housing body. According to this embodiment, the air intake housing has a further improved sealing effect at the opening of the third housing, thereby further improving the sealing performance of the air intake housing.

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

[0010] According to one embodiment, the first and second seals preferably intersect at the abutment location, with the second seal having a recessed portion for at least partially receiving the first seal. In the intake housing according to this embodiment, the contact sealing area formed by the first and second seals at the intersection is increased, thereby further enhancing the sealing effect of the first and second seals at the intersection.

[0011] According to one embodiment, preferably, the second seal has an embedded tooth, and the embedded tooth is embedded in the third housing body to define an embedded section. In the intake housing according to this embodiment, the second seal and the third housing body can be more firmly combined to improve sealing performance.

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

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

[0014] According to one embodiment, the third housing body preferably includes a fastening component, and the embedded section is disposed proximate to the fastening component. In the intake housing according to this embodiment, by disposing the embedded section near the fastening component, which is a critical stress point, the second sealing member near the fastening component can be securely bonded to the third housing body.

[0015] According to one embodiment, one of the first and second housings preferably includes a receiving groove for accommodating the first seal. The receiving groove extends along the junction of the first and second housings and has a first end and a second end. A guide post is provided near the first end and / or the second end to deflect the tip of the first seal toward the exterior of the intake housing. In the intake housing according to this embodiment, the tip of the first seal is deflected toward the exterior of the intake housing, allowing assemblers to easily confirm or inspect that the first seal has been installed in the first or second housing, thereby preventing missing installation and ensuring a good sealing effect.

[0016] According to one embodiment, the other of the first and second housings is preferably provided with a protrusion protruding toward the opposing housing. The protrusion is disposed proximate to the guide post and presses against the deflected end of the first sealing member. In the intake housing according to this embodiment, the end of the first sealing member can be securely held, thereby helping to ensure a sealing effect.

[0017] According to a second aspect of the present invention, a method for manufacturing a shell component is proposed, wherein the shell component is the third shell of any of the aforementioned air intake shells, and the method comprises: manufacturing a shell component body of the shell component; placing the shell 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 reserved in the cavity; and 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 fully matched with each other in shape and bonded to each other, so that the manufactured intake housing has significantly improved sealing performance while being simple to manufacture.

[0019] According to one embodiment, preferably, the sealing 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 sealing member, thereby ensuring both the strength of the third housing and its sealing performance after assembly with other housing components.

[0080] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of specific embodiments of the present invention. The same figure marks in the drawings represent the same elements. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0081] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning understood by persons of ordinary skill in the field to which the invention belongs. The words "first", "second" and similar terms used in the patent specification and claims of the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom" and the like indicate directions or positional relationships based on the directions 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 direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

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

[0083] Figures 1 and 2 respectively illustrate a perspective view and an exploded view of an air intake housing 100 according to an embodiment of the present invention. As shown in Figures 1 and 2, air intake housing 100 includes a first housing 1, a second housing 2, and a third housing 3. The second housing 2 is secured to the first housing 1 in a first direction (e.g., vertically downward in Figures 1 and 2), and the third housing 3 is secured to the first and second housings 1 and 2, which are secured to each other, in a direction different from the first direction (e.g., substantially horizontally to the left in Figures 1 and 2).

[0084] As further shown in FIG2 , a first sealing member 4 is provided between the first shell 1 and the second shell 2. The first sealing member 4 may be a sealing strip, which is configured to be arranged in a receiving groove 110 at the opening edge of the first shell 1. Specifically, as shown in FIG2 , the upward-facing opening of the first shell 1 is configured to engage with the downward-facing opening of the second shell 2. A section of the opening edge of the first shell 1 is configured to be covered from the right side by the third shell 3, while a section of the opening edge of the first shell 1 that is not covered by the third shell 3 (i.e., a section exposed to the outside of the air intake shell) is provided as a continuous receiving groove 110. Thus, the receiving groove 110 has a first end 111 and a second end 112, and the first sealing member 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 joined to each other and the first sealing member 4 is already disposed in the receiving groove 110, the raised edge section 210 at least partially enters the receiving groove 110 and presses the first sealing member 4, thereby sealing the air intake housing 100 in the opening edge section corresponding to the receiving groove 110.

[0086] With further reference to Figures 1 to 3 , as previously described, the third housing 3 is secured to the first and second housings 1 and 2 , which are secured to each other. As shown in Figures 2 and 3 , a first groove 120 is provided on the first housing 1 at a position for engaging a portion of the opening edge 301 of the third housing 3, and a second groove 220 is provided on the second housing 2 at a position for engaging another portion of the opening edge 301 of the third housing 3. When the first and second housings 1 and 2 are secured to each other, the first and second grooves 120 and 220 form an annular receiving space 125. In other words, the annular receiving space 125 is configured to receive the opening edge 301 of the third housing 3.

[0087] As shown in Figure 2, the third housing 3 includes a third housing body 310 and a second sealing member 320. The second sealing member 320 is annular and is disposed around the entire opening edge 301 of the third housing 3. In this embodiment of the present invention, the second sealing member 320 is an integral accessory to the third housing body 310, securely attached to the third housing body 310. When the third housing 3 is secured to the first and second housings 1 and 2, the second sealing member 320, along with the opening edge 311 of the third housing body 310, enters the annular accommodating space 125. The second sealing member 320 is compressed within the annular accommodating space 125, which at least substantially seals the third housing 3 from the outside.

[0088] According to the present invention, when the various housing components (i.e., the first housing 1, the second housing 2, and the third housing 3) are sealed and assembled together via the first seal 4 and the second seal 320, the first seal 4 and the second seal 320 are pressed together. In this embodiment of the present invention, the first seal 4 and the second seal 320 press against each other near the first end 111 and the second end 112 of the receiving groove, respectively. As a result, the first housing 1, the second housing 2, and the third housing 3 are also well sealed at their intersections. As a result, the entire air intake housing 100 is completely sealed from the outside world, and the air intake housing 100 also has significantly improved sealing performance compared to existing air intake housings.

[0089] 4A to 8D , the relevant structure of the air intake housing 100 will be further described.

[0090] Figures 4A and 4B respectively illustrate a top view and a perspective view of the first housing 1 of the air intake housing 100 according to an embodiment of the present invention, wherein the first seal 4 is installed in the receiving groove 110. As shown in Figures 4A and 4B, the ends of the first seal 4 extend beyond the first end 111 and the second end 112 of the receiving groove, respectively, and deflect outward. On the other hand, referring also to Figures 5A and 5B, the first end 111 of the receiving groove is 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 receiving space 125.

[0091] As specifically shown in Figures 5A and 5B , the space near the bottom of the first end 111 of the accommodating groove partially intersects with the space near the bottom of the first end 121 of the first groove 120, thereby forming a first abutting portion 130. Similarly, the space near the bottom of the second end 112 of the accommodating groove partially intersects with the space near the bottom of the second end 122 of the first groove 120, thereby forming a second abutting portion 140. By allowing the first seal 4 to enter the annular accommodating space 125 at the first abutting portion 130 and the second abutting portion 140, respectively, the assembled first seal 4 and second seal 320 can be pressed against each other, thereby completely sealing the entire intake housing 100 from the outside. See also Figure 6 , which shows only the perspective view of the first seal 4 and second seal 320 when assembled.

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

[0093] FIG7A also shows a first guide post 132 provided near the first end 111 of the receiving groove of the first housing 1, see also FIG7B . The first guide post 132 limits the specific extension direction of the end of the first seal 4 extending from the first end 111 of the receiving groove, causing the end to deflect toward the outside of the air intake housing 100. Thus, assemblers 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 to each other, thereby preventing missing installation while also ensuring the sealing performance of the first seal 4. Similarly, a second guide post 142 can be provided near the second end 112 of the receiving groove of the first housing 1. The second guide post 142 limits the specific extension direction of the end of the first seal 4 extending from the second end 112 of the receiving groove, causing the end to deflect toward the outside of the air intake housing 100.

[0094] Figure 7B also shows a corresponding portion of the second housing 2, including a first protrusion 232 disposed on the second housing 2 and protruding toward the first housing 1. The first protrusion 232 is disposed near the first guide post 132 and presses against the deflected end of the first seal 4 to further secure the first seal 4 and ensure the extension direction of the end. Similarly, the second housing 2 may also be provided with a second protrusion 242 protruding toward the first housing 1. The second protrusion 242 is disposed near the second guide post 142 and presses against the deflected end of the first seal 4. Alternatively, guide members and protrusions of other configurations may be provided at the first end 111 and / or the second end 112 of the accommodating groove to deflect the end of the first seal 4 toward the exterior of the air intake housing.

[0095] Figures 8A and 8B respectively illustrate partial perspective views of a second seal 320 disposed near the first end 111 and the second end 112 of the receiving groove according to an embodiment of the present invention. Figures 8C and 8D respectively illustrate partial perspective views of a first seal 4 and a second seal 320 disposed near the first end 111 and the second end 112 of the receiving groove according to an embodiment of the present invention in an assembled position. As shown in Figures 8A-8D, the second seal 320 has a recess 321 near the first end 111 of the receiving groove to at least partially receive the first seal 4, and the second seal 320 and the first seal 4 are pressed against and intersected at the recess 321. The second seal 320 has a recess 322 near the second end 112 of the receiving groove to at least partially receive the first seal 4, and the second seal 320 and the first seal 4 are pressed against and intersected at the recess 322. Therefore, when the first seal 4 and the second seal 320 are assembled together in the air intake housing 100, the contact area at the intersection of the first seal 4 and the second seal 320 is increased, thereby improving the sealing effect of the intersection, and at the same time preventing the first seal 4 and the second seal 320 from being difficult to install or the seals from being broken due to excessive pressure between each other.

[0096] The air intake housing 100 having the above-mentioned structure can be assembled through the following steps: first, the first housing 1 is fixed in an orientation with its opening facing upward, and the first seal 4 is placed in the accommodating groove 110. The first seal 4 is in a naturally stretched state in the accommodating groove 110, and the orientations of the two end heads of the first seal 4 located on the outside of the two ends of the accommodating groove 110 are roughly fixed by the guide columns 132 and 142; then, the second housing 2 is placed above the first housing 1, and the raised edge section 210 of the second housing 2 at least partially enters the accommodating groove 110 and abuts 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 squeezes 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, and the opening edge 301 of the third housing 3 together with the second seal 320 at least partially enters the annular accommodating space 125, and then the third housing 3 is fixed to the first housing 1 and the second housing 2 fixed to each other, for example, by screws, and this step squeezes the second seal 320.

[0097] 9A to 11 , some advantageous specific structures of the third housing 3 will be described, especially the configuration of the cooperation between the second sealing member 320 and the third housing body 310 .

[0098] 9A and 9B illustrate the third housing 3 without and with the second seal 320, respectively. As previously described, the second seal 320 is disposed around the entire opening edge 301 of the third housing 3. Referring also to FIG10A and FIG10B , the second seal 320 has one or more embedded teeth 323 in some sections thereof, thereby defining embedded sections 324. These embedded teeth 323 are embedded in one or more corresponding grooves 313 in the opening edge 311 of the third housing body 310, thereby more firmly fixing the second seal 320 and the third housing body 310 to each other.

[0099] In Figures 9A and 9B , each embedded section 324 is provided near the fastening member 330 of the third housing 3, which is used to secure the third housing 3 to the first housing 1 or the second housing 2. Because the portion of the third housing 3 near the fastening member 330 is subject to greater deformation and pressure, providing the embedded sections 324 near the fastening member 330 is particularly effective in preventing the second sealing member 320 from detaching from the third housing body 310 near the fastening member 330. However, the embedded sections 324 may also be provided at other locations on the opening edge 301 of the third housing 3.

[0100] Further reference is made to Figures 10A and 10B , which respectively illustrate partial cross-sectional views of the third housing 3. In the cross-sectional views shown in Figures 10A and 10B , the second sealing member 320 and the third housing body 310 form a V-shaped edge, with the outer branch 328 of the V-shaped edge formed by the second sealing member 320, and the inner branch 318 of the V-shaped edge formed by the third housing body 310. Compared to the prior art arrangement of a separate sealing ring at the housing opening edge, the above-described configuration of the present invention ensures that the opening edge 301 of the third housing 3 near its top has both higher structural strength and better sealing performance. This V-shaped edge structure can be continued into the aforementioned embedded section 324, with a portion of the inner branch 318 of the V-shaped edge formed from the material of the second sealing member 320, ensuring a secure local bond between the second sealing member 320 and the third housing body 310 and a good overall sealing effect.

[0101] Figure 11 shows the side of the third housing 3 opposite the opening, specifically the support rib 326 of the second sealing member 320. Referring also to Figure 10A , the support rib 326 extends toward the third housing body 310. In Figures 10A and 11 , the support rib 326 extends from the second sealing member 320 toward the outer surface 340 of the third housing body 310 and is supported between the second sealing member 320 and the outer surface 340, thereby further supporting the bonding of the second sealing member 320 to the third housing body 310 and the sealing effect of the second sealing member 320.

[0102] The third housing 3 shown in Figures 9A-11 can be manufactured using the manufacturing method shown in Figures 12-16, achieving a good form fit and bonding effect between the second seal 320 and the third housing body 310. Hereinafter, the third housing 3 is also referred to as the housing component 3, and the manufacturing method described below is applicable to the manufacture of housing components requiring such a seal.

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

[0104] In this method, the housing component body 310 of the housing component 3 is first manufactured. This housing component body 310 is then placed in a mold cavity formed by a first mold 5 and a second mold 6, as shown in Figures 13-15 . This allows for a seal molding space corresponding to the second seal 320 to be left in the mold cavity. Specifically, as shown in Figures 12A and 12B , the mold cavity surfaces of the first mold 5 and the second mold 6 substantially correspond to the exterior and interior surfaces of the housing component body 310, with only partial seal molding spaces 505 and 605, respectively, left at locations corresponding to the second seal 320. After the housing component body 310 is placed in the mold cavity and the first mold 5 and the second mold 6 are closed, the partial seal molding spaces 505 and 605 together form a seal molding space corresponding to the second seal.

[0105] Next, as shown in FIG16 , a sealing material is injected into the sealing molding space (e.g., through the injection hole 501 shown in FIG12A ) to form the second sealing member 320. After the sealing material solidifies, the second sealing member 320 is integrated with the housing component main body 310. The first mold 5 and the second mold 6 can then be separated to remove the integrated housing component 3.

[0106] In an embodiment according to the present invention, the housing body 310 is made of hard plastic, while the second sealing member 320 is made of soft plastic. This ensures the mechanical strength of the housing body 3 and the sealing effect of the opening edge. For example, the housing body 310 can be made of plastic, and the second sealing member 320 can be made of rubber.
