Description

Technical Field

[0001] The present disclosure relates to an air duct component and an air supply assembly comprising the air duct component. Background Art

[0002] Duct components are an important part of vehicle air conditioning and sensor cleaning systems. Due to the limitation of vehicle body space, duct components are mostly irregular in shape, which can be called special-shaped duct components. Duct components can usually be made by injection molding or blow molding. Although the injection molding process has low cost and the product has high dimensional accuracy, it has certain limitations on the spatial structure of duct components and is not suitable for the preparation of irregularly shaped duct components. Although the blow molding process can prepare special-shaped duct components, it is expensive, the dimensional accuracy of the product is poor, and there are certain limitations on materials and product thickness.

[0003] In addition, the outlet of the air duct component is usually plugged with a nozzle, which requires the air duct component to have not only a certain strength, but also a certain flexibility in the area where the nozzle is plugged, so that the nozzle can be inserted into the air duct component in a sealed manner and the assembly tolerance between the two can be compensated. However, most of the existing air duct components are made of plastic, which not only cannot ensure the sealing of the connection between the nozzle and the air duct component, but also cannot compensate for the assembly tolerance between the two. Some other air duct components are made of rubber, which makes the air duct component too soft and difficult to insert components such as nozzles.

[0004] Therefore, how to design an irregularly shaped air duct component that can not only reduce the preparation cost and have higher dimensional accuracy and structural strength, but also sealably plug the nozzle and compensate for the assembly tolerance between the two has become an urgent problem to be solved. Summary of the invention

In addition, the air duct component can also include a seal arranged at the outlet of the air duct housing, and the air duct housing with greater hardness provides structural strength, and the seal provides flexibility at the connection, so as to facilitate the insertion of the nozzle into the air duct component and ensure the sealing performance of the connection.

[0046] The following describes the implementation of the present disclosure through specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification.

[0047] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings attached to this specification are only used to match the contents disclosed in the specification for the understanding and reading of those skilled in the art, and are not used to limit the limiting conditions for the implementation of the present disclosure, so they have no substantial technical significance. Any structural modification, change in proportional relationship, or adjustment of size, without affecting the effects and purposes that can be achieved by the present disclosure, should still fall within the scope of the technical contents disclosed by the present disclosure. At the same time, the terms such as "on" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present disclosure. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present disclosure without substantially changing the technical contents.

[0048] In order to more clearly understand the present disclosure, various embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0049] The present disclosure provides an irregularly shaped air duct component 1, see Figure 1 and Figure 2 , the air duct component 1 includes an air duct housing H. The air duct housing H can be made of a plastic with a relatively high hardness, and the air duct housing H has an inlet H1 (also called an air inlet) for connecting to an air source, an outlet H2 (also called an air outlet) for connecting to an insert component such as a nozzle, and an air duct between the inlet H1 and the outlet H2. The air duct housing H includes a first shell half 10 and a second shell half 20, both of which extend from the inlet H1 to the outlet H2, and are fixed to each other to define an air duct between the first shell half 10 and the second shell half 20. In this way, the irregularly shaped air duct component 1, especially the design of dividing the air duct housing H of the air duct component 1 into two parts (i.e., the first shell half 10 and the second shell half 10), enables each part to be manufactured by injection molding, with low preparation cost, and high dimensional accuracy of the manufactured product, avoiding the problem that the injection molding process is limited by the spatial structure of the air duct component.

[0050] See also Figure 2 and Figure 3 The first shell half 10 may be roughly ∩-shaped, and the second shell half 20 may be roughly ∪-shaped, and the two are butted at the interface edge, and can be fixed together by the first fixing member 101. The first fixing members 101 (10 are described in the present disclosure, but are not limited thereto) can be distributed along the outer side of the interface edge of the first shell half 10 and the second shell half 20, so that the first and second shell halves 10 and 20 can be fixed without being restricted by the limited vehicle body space and avoiding interference with the vehicle body.

[0051] Specifically, the first fixing member 101 may include a protrusion 12 and a snap ring 22 that can cooperate with each other. The protrusion 12 is arranged on the first shell half 10 and arranged along the outer side of the interface edge of the first shell half 10. Correspondingly, the snap ring 22 is arranged on the second shell half 20 and arranged along the outer side of the interface edge of the second shell half 20. The snap ring 22 can be snapped / engaged on the protrusion 12 to fix the first shell half 10 and the second shell half 20 together. This assembly method is easy to operate and has a simple structure. Of course, the present disclosure is not limited to this. For example, the protrusion 12 can also be arranged on the second shell half 20, and correspondingly, the snap ring 22 is arranged on the first shell 10, as long as the first shell half 10 and the second shell half 20 can be fixed together.

[0052] Please continue to see Figure 1 and Figure 2 Since the outlet H2 of the air duct component 1 is generally a long and flat mouth, it is easy to deform under the action of external force. In order to avoid this problem, the air duct component 1 can also be provided with a second fixing member 102 inside it (the present disclosure is described with two, but is not limited to this). The second fixing member 102 is close to the outlet H2 of the air duct component 1, and includes a first connector (not shown) arranged on the inner wall of the first shell half 10 and facing the second shell half 20 and a second connector 23 arranged on the inner wall of the second shell half 20 and facing the first shell half 10. The second connector 23 can be fixedly plugged into the first connector to support and lock the first shell half 10 and the second shell half 20, thereby effectively improving the structural strength and stability of the air duct component 1. Of course, the present disclosure is not limited to this. For example, the first connector may also be arranged on the inner wall of the second shell half 20, and the second connector 23 may be correspondingly arranged on the first shell half 10. Alternatively, the air duct component 1 may not be provided with the second fixing member 102, but a reinforcing rib is provided on the first shell half 10 or the second shell half 20 to abut against the other shell half (wherein the reinforcing rib extends along the air duct direction), as long as the structural strength and stability of the air duct component 1 can be increased.

[0053] See also Figure 4 and Figure 5Preferably, in order to improve the sealing performance of the connection between the first shell half 10 and the second shell half 20, a protrusion 11 may be provided on the interface edge of one of the first shell half 10 and the second shell half 20, and a groove 21 capable of receiving the protrusion 11 may be provided on the interface edge of the other. The protrusion 11 is located in the groove 21 and presses against at least one surface of the groove 21, or the protrusion 11 may be inserted into the groove 21 in an interference fit manner, thereby increasing the contact area between the first shell half 10 and the second shell half 20 and improving the sealing performance therebetween. Moreover, even if the interface edge of the first shell half 10 and the second shell half 20 is not tightly fitted due to manufacturing tolerances or the like, the above-mentioned arrangement of the protrusion 11 and the groove 21 can also ensure the sealing performance of the connection between the first and second shell halves 10 and 20. In this embodiment, the protrusion 11 is provided on the first shell half 10, and correspondingly, the groove 21 is provided on the second shell half 20, and the two side walls of the protrusion 11 abut against / closely fit the two side walls of the groove 12 to improve the sealing performance at the connection between the first shell half 10 and the second shell half 20. Of course, the present disclosure is not limited to the above structure, for example, the interface edges of the first shell half 10 and the second shell half 20 may also be provided with a plurality of protrusions 11 and grooves 21, or may be provided with mutually matching sawtooth structures, as long as the sealing performance at the connection between the two can be improved.

[0054] Please return to see Figure 2 The air duct component 1 may further include a sealing member 30 which is generally in the shape of a short tube. The sealing member 30 may be made of a rubber material having a hardness lower than that of plastic. The sealing member 30 is at least partially disposed between the first housing half 10 and the second housing half 20 and is located at the outlet H2 of the air duct housing H, and is used to connect a plug-in component such as a nozzle to the outlet H2 so that the plug-in component can be sealedly connected to the air duct housing H.

[0055] In one embodiment, if Fig. 9 As shown, the seal 30 may be provided with at least one first annular protrusion 31 located upstream (the present disclosure is described as two, but is not limited to this) and at least one second annular protrusion 32 located downstream (the present disclosure is described as two, but is not limited to this) on its inner wall. Such a configuration can further improve the sealing between the nozzle and the air duct housing H when a plug-in component such as a nozzle is inserted into the outlet H2. At the same time, when the plug-in component such as the nozzle has a large assembly tolerance, it can also be compensated by the first and second annular protrusions 31 and 32.

[0056] In another embodiment, if Fig.14 and 15As shown, the seal 30 may include a flat ring-shaped body 33 and a flange 34 extending laterally outward (in the up and down directions as shown in the figure) from the flat ring-shaped body 33. Such an arrangement can perform sealing through the flat ring-shaped body 33 and the flange 34 when a plug-in component such as a nozzle is inserted into the outlet H2, thereby effectively improving the sealing between the nozzle and the air duct housing H.

[0057] It can be seen that the special-shaped air duct component 1 provided by the present disclosure is divided into the air duct housing H as the first housing half and the second housing half, so that the first housing half and the second housing half can be made by injection molding process, the preparation cost is low, and the product size precision is high, which can avoid the problem that the injection molding process is limited by the spatial structure of the air duct component. The air duct component 1 of the present disclosure may also include a seal 30 arranged at the outlet, so that when plugging in plug-in components such as nozzles, the sealing between the air duct housing H and the plug-in components can be ensured. Moreover, the flow channel component 1 of the present disclosure can be provided with structural strength by the air duct housing H with greater hardness, and the flexibility of the connection can be provided by the seal 30 to ensure the sealing performance. In addition, the present disclosure sets a first fixing part 101 on the outer side of the interface edge of the first and second housing halves 10 and 20, wherein the first fixing part 101 includes a mutually matching protrusion 12 and a snap ring 22, so that it is not only convenient for the assembly of the first and second housing components 10 and 20, but also the above-mentioned arrangement is not limited to the limited vehicle body space, and can avoid interference with the vehicle body. In addition, the present disclosure may also provide mutually matching protrusions 11 and grooves 21 on the interface edges of the first and second shell halves 10 and 20 to effectively improve the sealing performance of the connection between the first and second shell halves 10 and 20 .

[0058] The present disclosure also provides an air supply assembly, and various embodiments of the air supply assembly of the present disclosure are described below in conjunction with the accompanying drawings.

[0059] See also Figure 6 and Figure 7 The air supply assembly includes the aforementioned air duct component 1 and a nozzle 2. The nozzle 2 can be partially inserted into the outlet H2 of the air duct component 1 and is sealedly connected to the air duct component 1. Figure 6 and Figure 7 Also shown is a wind source 3 (eg, a blower, etc.), which is connected to the inlet H1 of the air duct component 1 in the air supply assembly to transport / inject air (wind) to a specific location through the air supply assembly.

[0060] See also Figure 8 and Fig. 9, the nozzle 2 is inserted into the outlet H2 of the air duct housing H, and the seal 30 is clamped between the nozzle 2 and the air duct housing H to ensure the sealing of the connection between the air duct component 1 and the nozzle 2. Specifically, the seal 30 may be roughly in the shape of a short tube and located in the outlet H2 of the air duct component 1. Preferably, as mentioned above, the seal 30 may be provided with at least one first annular protrusion 31 located upstream and at least one second annular protrusion 32 located downstream on its inner wall, so that when the nozzle 2 has an installation deviation, it can be compensated by the first and second annular protrusions 31 and 32, further effectively ensuring the sealing of the connection.

[0061] Specifically, when the nozzle 2 is installed to be located at Fig.10 When the nozzle 2 is in the 2′ position (i.e., the nozzle 2 has a counterclockwise installation deviation), the lower portion of the nozzle 2 close to the second shell half 20 abuts against the first annular protrusion 31 of the compression seal 3, and the upper portion of the nozzle 2 close to the first shell half 10 abuts against the second annular protrusion 32 of the compression seal 3, which can effectively ensure the sealing of the connection between the nozzle 2 and the air duct component 1. Fig.10 When the nozzle 2 is at the 2″ position (i.e., the nozzle 2 has a clockwise installation deviation), the upper portion of the nozzle 2 close to the first shell half 10 abuts against the first annular protrusion 31 of the compression seal 3, and the lower portion of the nozzle 2 close to the second shell half 20 abuts against the second annular protrusion 32 of the compression seal 3 to ensure the sealing of the connection. It can be seen that the above-mentioned arrangement of the seal 3 can ensure the sealing of the connection when the nozzle 2 has an installation deviation.

[0062] Please continue to see Fig. 9 and Fig.10 The outer peripheral wall of the nozzle 2 may be provided with a first boss 201 surrounding the nozzle 2, and the first boss 201 is used to further abut the sealing member 3 to further improve the sealing performance of the connection between the nozzle 2 and the air duct component 1. Fig. 9 and Fig.10 In the cross-sectional view shown, the first boss 201 may be substantially in the shape of an arc-shaped protrusion, so as to facilitate insertion into the outlet H2 of the air duct component 1, and when the nozzle 2 has an installation deviation, the provision of the first boss 201 may also ensure the sealing of the connection between the nozzle 2 and the air duct component 1. In one embodiment, the first boss 201 of the nozzle 2 may be located between the first annular protrusion 31 and the second annular protrusion 32 of the sealing member 3 to multiple ensure the sealing of the connection.

[0063] The following will describe different embodiments of the air supply assembly of the present disclosure. For simplicity, the following will mainly describe the differences between the embodiments, and the similarities will not be repeated. In addition, the same elements in the embodiments of the present disclosure are marked with the same reference numerals to facilitate mutual comparison between the embodiments.

[0064] Fig.11 Another embodiment of the air supply assembly is shown. As shown in the figure, the air supply assembly includes an air duct component 1 and a nozzle 2 sealed and connected to the outlet H2 of the air duct component 1. Figure 7 The difference between the illustrated embodiments is that the shape of the inlet H1 of the air duct component 1 is different. In the present embodiment, the inlet H1 of the air duct component 1 is circular to facilitate the connection of components such as pipes.

[0065] See also Fig.14 and Fig.15 , a sealing member 30 is sandwiched between the air duct component 1 and the nozzle 2. The sealing member 30 may include a flat ring-shaped body 33 and a flange 34 extending laterally outward (in the up-down direction as shown in the figure) from the flat ring-shaped body 33, wherein the flat ring-shaped body 33 is located in the outlet H2 of the air duct component 1, and the flange 34 is located outside the outlet H2 of the air duct component 1. The nozzle 2 may be partially inserted into the outlet H2 of the air duct component 1, and press against the flat ring-shaped body 33 of the sealing member 30, so that the connection between the nozzle 2 and the air duct component 1 is sealed. Preferably, as Fig.11 , Fig.14 and Fig.15 As shown, the outer peripheral wall of the nozzle 2 may also be provided with a second boss 202 surrounding the nozzle 2. The second boss 202 cooperates with the air duct housing H of the air duct component 1 to clamp the flange 34 of the seal 3 to increase the sealing area between the nozzle 2 and the air duct component 1.

[0066] Please continue to see Figures 11 to 15 , the air supply assembly may include a fastener 4 arranged along the connection between the nozzle 2 and the air duct component 1, which is used to fix the nozzle 2 to the air duct component 1 and maintain the clamping force of the nozzle 2 and the air duct component 1 on the flange 34. Specifically, the fastener 4 may include a first fastening portion 401 and a second fastening portion 402 that can be fastened to the first fastening portion 401. The first fastening portion 401 may be roughly in the form of a snap ring and may be arranged on the second boss 202 of the nozzle 2. Correspondingly, the second fastening portion 402 may be roughly in the form of a convex block and be arranged on the outer wall of the air duct component 1. In this way, the nozzle 2 can be fixed to the air duct component 1 by the first fastener 401 being engaged with the second fastening portion 402, and the clamping force on the flange 34 can be maintained. The structure is simple and easy to operate.

[0067] It can be seen that the nozzle 2 and the air duct component 1 of this embodiment can increase the sealing area between the nozzle 2 and the air duct component 1 by clamping the flat ring-shaped body 33 and the flange 34 of the seal 30, thereby more effectively ensuring the sealing of the connection.

[0068] Although the present disclosure is described as the seal 30 having the first and second annular protrusions 31 and 32, and the nozzle 2 having the first boss 201, the present disclosure is not limited to this. For example, the seal 30 and the nozzle 2 may not have the above-mentioned settings, or only the first and second annular protrusions 31 and 32 may be provided on the seal 30, or only the first boss 201 may be provided on the nozzle 2, as long as the nozzle 2 can press against the inner wall of the seal 30 to seal the connection.

[0069] In addition, the seal 30 of the present disclosure is described as an independent component, but the present disclosure is not limited thereto. For example, the seal 30 can also be overmolded on the nozzle 2 as long as a good seal can be ensured at the connection between the nozzle 2 and the air duct component 1. The nozzle 2 and the seal 30 are formed into one piece to simplify the processing technology and facilitate assembly.

[0070] In addition, the air duct component 1 of the present disclosure is described by dividing the air duct housing H into two parts, namely, the first and second housing halves 10 and 20, but the present disclosure is not limited thereto. For example, the air duct component 1 can also divide the air duct housing H into three or more parts according to the limitation of the vehicle body space, as long as each part can be made by injection molding process and can be sealed and conveniently connected together. Moreover, the air duct component 1 of the present disclosure is not limited to the specific shapes of the inlet H1 and the outlet H2, as long as the inlet H1 and the outlet H2 can be sealed and connected to other parts.

[0071] Furthermore, the air supply assembly of the present disclosure is described as connecting the air source 3 to the inlet H1 of the air duct component 1 and conveying air, but the present disclosure is not limited to this. For example, the inlet H1 of the air duct component 1 can be connected to other fluid sources as long as it can convey fluid.

[0072] In summary, the present disclosure provides a special-shaped air duct component and an air supply assembly including the air duct component. The air duct component can be made by injection molding process by dividing the air duct housing into a first housing half and a second housing half, etc., with low preparation cost and high dimensional accuracy of the product, which can avoid the problem that the injection molding process is limited by the spatial structure of the air duct component. In addition, the air duct component can also include a seal arranged at the outlet of the air duct housing, and the air duct housing with greater hardness provides structural strength, and the seal provides flexibility at the connection to facilitate the insertion of the nozzle into the air duct component and ensure the sealing performance of the connection. In addition, the first and second housing components of the air duct housing are respectively provided with mutually matching protrusions and snap rings (i.e., first fixing members) on the outer sides of the interface edges thereof, so that the air duct housing can be easily assembled, and is not limited by the limited vehicle body space. The air supply assembly of the present disclosure includes the above-mentioned air duct component and a nozzle that can be sealably connected to the outlet of the air duct component, which is easy to assemble. The air supply component can effectively ensure the sealing of the connection by clamping a seal between the air duct shell and the nozzle of the air duct component, and a fastener is provided at the connection between the air duct component and the nozzle, which can effectively maintain the clamping force of the seal and ensure the sealing of the seal.

[0073] The above describes exemplary implementations of the air duct components and air supply components provided by the present disclosure with reference to preferred embodiments. However, those skilled in the art will appreciate that, without departing from the concept of the present disclosure, various modifications and variations may be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure may be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the appended claims.
