Abstract
Description
Technical Field
[0001] This application relates to the field of thermal management system technology, specifically to an integrated component and its assembly method. Background Technology
[0002] The integrated component includes a substrate with flow channels inside. Multiple components, such as electronic expansion valves and sensors, are mounted on the substrate. These components are connected to the flow channels inside the substrate, meaning that the substrate integrates the connection channels of multiple components inside the substrate.
[0003] These components are threaded to the substrate. During assembly, a robotic arm is needed to screw multiple components into the corresponding threaded holes in the base. However, to reduce the possibility of valve bodies and seats jamming, a high-precision robotic arm and tightening gun are required for assembling the components using threaded connections. Alternatively, welding can be used to fix multiple components to their corresponding positions on the substrate. Both of these assembly methods require expensive equipment, resulting in high assembly costs. Summary of the Invention
[0004] The purpose of this solution is to provide an integrated component and its assembly method, which can reduce the assembly cost of the integrated component.
[0005] To address the aforementioned technical problems, this solution provides an integrated component including a flow channel component, a fluid handling component, and a limiting component. One of the flow channel component and the limiting component is connected to a snap-fit portion, which is snap-fitted to the other of the flow channel component and the limiting component. The flow channel component has a flow channel portion and an interface portion, the inner cavity of the interface portion communicating with the inner cavity of the flow channel portion, and the interface portion being capable of connecting to the fluid handling component.
[0006] The limiting component has an insertion hole, which is inserted into and fitted with the fluid processing component; at least a portion of the fluid processing component is located between the flow channel component and the limiting component.
[0007] Because the limiting component has an insertion hole that mates with the fluid handling component, after the limiting component and the fluid handling component are inserted, at least a portion of the fluid handling component is located between the flow channel component and the limiting component. Furthermore, since one of the flow channel component and the limiting component is connected by a snap-fit part, which in turn snaps into the other of the flow channel component and the limiting component, the fluid handling component can be installed onto the flow channel component simply by snapping the limiting component and the flow channel component together. The snap-fit action is simple to implement, which reduces the requirements for the equipment and thus reduces the equipment investment cost.
[0008] This solution also provides a method for assembling integrated components, including:
[0009] The fluid handling component is installed at the interface of the flow channel component;
[0010] The limiting component is placed over the flow channel processing component, such that a portion of the fluid processing component passes through the insertion hole of the limiting component, and the flow channel component and the limiting component are snapped together.
[0011] This assembly method is simple to assemble, easy to operate, and can reduce installation costs when assembling integrated components. Attached Figure Description

[0043] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0044] In the embodiments of this application, the terms "first" and "second" are used only to distinguish different components and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.
[0045] Please refer to Figures 1-4 , Figure 1 This is a schematic diagram of the integrated component in the first embodiment of this application; Figure 2 for Figure 1 Exploded view; Figure 3 for Figure 1 Top view; Figure 4 for Figure 3 A sectional view along line AA.
[0046] The integrated component in this embodiment includes a flow channel component 100, a fluid handling component 300, and a limiting component 200. The flow channel component 100 has a flow channel portion 102 (shown in...). Figure 4 The interface part 101 and the flow channel part 100 can be Figure 2 The structure shown is generally plate-shaped or shell-shaped. The flow channel 102 is a channel structure set inside the plate-shaped or shell-shaped structure. There can be multiple flow channel 102 distributed inside the flow channel component 100. The flow channel component 100 can be directly formed by casting, injection molding, extrusion or other methods. The flow channel 102 can be directly formed in the casting, injection molding or extrusion process. Alternatively, an integral blank of the flow channel component 100 can be prepared first, and then the flow channel 102 located inside can be processed by machining or other methods.
[0047] The inner cavity of the interface portion 101 of the flow channel component 100 communicates with the inner cavity of the inner flow channel portion 102. The interface portion 101 is located on the outer side of the flow channel component 100. Specifically, the flow channel component 100 has a first side facing the limiting member 200, and the interface portion 101 is located on the first side. The interface portion 101 can be connected to an external fluid processing component 300, which is part of an integrated assembly. The fluid processing component 300 is, for example, a... Figure 2 The valve device shown can control the flow of fluid, such as opening and closing or throttling. Specifically, the valve device can be a throttle valve, a check valve, or a control valve. The fluid processing component 300 can also be other components besides the control valve that process the fluid, such as a heat exchanger, a liquid receiver, a gas-liquid separator, or a sensor. The interface portion 101 of the flow channel component 100 is used to connect with the fluid processing component 300. The interface portion 101 has an interface hole 101a that mates with the fluid processing component 300. Fluid within the fluid processing component 300 can flow through the interface portion 101 to the flow channel portion 102 inside the flow channel component 100, or fluid in the flow channel portion 102 can also flow through the interface portion 101 into the fluid processing component 300. Thus, fluid can flow in one or more fluid processing components 300, forming one or more loops. As can be seen, in this embodiment, the flow channel component 100 integrates the pipelines that connect multiple fluid processing components 300 to each other into its internal flow channel part 102. This integrated component has a compact and simple structure and does not require multiple external pipelines.
[0048] This application does not impose restrictions on the specific structural form, processing method, or extension path of the flow channel component 100 within the flow channel component 100. The selection and configuration can be made according to different circuit requirements and different connection requirements of the fluid processing component 300.
[0049] It is worth noting that the flow channel component 100 and the limiting component 200 of the integrated component are snap-fitted together, and at least a portion of the fluid handling component 300 is located between the flow channel component 100 and the limiting component 200, that is, the fluid handling component 300 can be limited between the flow channel component 100 and the limiting component 200.
[0050] Specifically, one of the flow channel component 100 and the limiting component 200 is connected to a snap-fit part 201, and the snap-fit part 201 is snap-fit connected to the other of the flow channel component 100 and the limiting component 200. The following embodiments mainly describe the limiting component 200 being connected to the snap-fit part 201 and the snap-fit part 201 being snap-fit with the flow channel component 100. However, it is obvious that the flow channel component 100 is connected to the snap-fit part 201 and the snap-fit part 201 is also the same, so it will not be described again.
[0051] like Figure 2 As shown, the limiting component 200 includes a plate body 205, which is generally a flat plate structure. The snap-fit portion 201 of the limiting component 200 is specifically a snap-fit 201A, which snaps into and connects to the flow channel component 100. At this time, the interface portion 101 of the flow channel component 100 is located on the side of the flow channel component 100 closest to the limiting component 200, i.e., located... Figure 2 On the upper side of the flow channel component 100, the interface portion 101 protrudes upwards. After the flow channel component 100 and the limiting component 200 are snapped together, the interface portion 101 of the flow channel component 100 faces the limiting component 200. The main body portion of the flow channel component 100 with the flow channel portion 102 can be defined as the flow channel body portion 103. The flow channel portion 102 is located inside the flow channel body portion 103. The flow channel body portion 103 has a flat plate structure or a shell structure. For example, the shell structure is a thinner shell structure similar to the flat plate structure to reduce space occupation.
[0052] like Figure 5 As shown, Figure 5 for Figure 2 Enlarged view of part B in the middle.
[0053] The interface portion 101 protrudes outward relative to the main body portion 103 of the flow channel. The interface portion 101 is located on the side of the main body portion 103 of the flow channel near the limiting member 200. Figure 4The assembled interface portion 101 will be located between the main body of the flow channel 103 and the limiting member 200. The hole wall portion of the interface portion 101 may be provided with a second stepped portion 1011 to form a second stepped wall 10111 facing the limiting member 200. The fluid handling component 300 may have a mating portion 301 that engages with the second stepped wall 10111. The mating portion 301 protrudes from the main body portion of the fluid handling component 300. After the fluid handling component 300 is inserted into the interface portion 101, the mating portion 301 of the fluid handling component 300 and the second stepped wall 10111 of the flow channel component 100 abut against each other, thus the fluid handling component 300 is inserted into place. The fluid handling component 300 and the interface portion 101 may be sealed, for example, by providing a sealing ring between them.
[0054] In addition, such as Figure 2 As shown, the limiting member 200 has an insertion hole 200a, which penetrates the limiting member 200 along its thickness direction, specifically penetrating the plate body 205. The thickness direction of the limiting member 200 is also the engagement direction between the limiting member 200 and the flow channel member 100. This engagement direction can be defined as the first direction, such as... Figure 4 As shown, the thickness directions of both the limiting component 200 and the flow channel component 100 are in the first direction. After they are snapped together, they cannot be separated in the first direction. Furthermore, the limiting component 200 can be defined as being located above the flow channel component 100, meaning that the two are... Figure 2 , 4 In the orientation shown, the limiting component 200 is located above, and the flow channel component 100 is located below.
[0055] The insertion portion 200a of the limiting member 200 is used for insertion and mating with the fluid handling member 300. The insertion portion 200a and the fluid handling member 300 may have a radial gap. The insertion portion 200a can be a through-hole structure or a blind-hole structure. The end of the insertion portion 200a closest to the limiting member 200 is the first end, and the other end of the insertion portion 200a furthest from the limiting member 200 is the second end. During assembly, the fluid handling member 300 is first installed onto the interface portion 101 of the flow channel member 100, and then the flow channel member 100 and the limiting member 200 are assembled. At this time, a portion of the fluid handling member 300 can pass through the insertion portion 200a from the first end to the second end. Figure 2 , 4 From a certain perspective, a portion of the fluid handling component 300 can pass through the insertion portion 200a of the limiting component 200 from bottom to top. A portion of the assembled fluid handling component 300 will be located within the interface portion 101 for connection. A portion of the fluid handling component 300 will also be located within the insertion portion 200a, while another portion will protrude from the insertion portion 200a to be located on the side of the limiting component 200 opposite to the flow channel component 100. Figure 1As shown, a portion of the fluid handling component 300 is located above the limiting component 200.
[0056] Combination Figure 2 Understandably, the integrated components in this embodiment specifically include a first valve device 300A, a second valve device 300B, a third valve device 300C, a fourth valve device 300D, and a fifth valve device 300E. Correspondingly, the flow channel component 100 is provided with five corresponding interface portions 101, which protrude upward relative to the flow channel body portion 103, such as... Figure 5 As shown, the interface section 101 is a columnar structure, or a cylindrical structure, with a through-hole. The lower end of the valve device can be inserted into the interface section 101 to connect with the corresponding flow channel section 102. Depending on the structure and size of different valve devices, the structure and size of the interface section 101 will be set accordingly to allow a part of the valve device to pass through the corresponding insertion hole section 200a. Figure 2 In the first valve device 300A, the second valve device 300B, and the third valve device 300C are relatively small in size, with the corresponding three interface parts 101 being thinner and the three insertion holes 200a being smaller in diameter. The fourth valve device 300D and the fifth valve device 300E are relatively large in size, with the corresponding two interface parts 101 being thicker and the two insertion holes 200a being larger in diameter.
[0057] Further reference is available. Figures 6-8 , Figure 6 for Figure 4 Enlarged view of section C; Figure 7 for Figure 2 Schematic diagram of the structure of the second valve device 300B; Figure 8 for Figure 2 A schematic diagram of the middle limiting component 200 shows the side of the limiting component 200 facing the flow channel component 100.
[0058] To confine at least a portion of the fluid handling component 300 between the flow channel component 100 and the limiting component 200, the limiting component 200 in this embodiment further includes a limiting structure 200a11 for restricting the fluid handling component 300 from disengaging from the interface portion 101 in a direction away from the flow channel component 100. To achieve this, the fluid handling component 300 has a mating portion 301, and the limiting structure 200a11 is located on the side of the mating portion 301 of the fluid handling component 300 away from the flow channel component 100. Figure 7The limiting structure 200a11 is located on the upper side of the mating portion. Furthermore, when projected along the engagement direction of the flow channel component 100 and the limiting component 200, i.e., along the first direction (the engagement direction), at least a portion of the projection of the limiting structure 200a11 coincides with the projection of the mating portion 301. Thus, when the fluid handling component 300 moves in the direction of disengagement from the interface portion 101, the mating portion 301 and the limiting structure 200a11 abut against each other, restricting the movement of the fluid handling component 300.
[0059] As mentioned above, the fluid handling component 300 can extend out of the socket portion 200a from the first end to the second end. Figure 4 If the fluid handling component 300 extends upward through the insertion hole 200a, without a limiting structure, it may detach upward from the flow channel component 100, affecting the connection reliability between the fluid handling component 300 and the interface portion 101. The limiting structure 200a11 restricts the position of the fluid handling component 300 and the limiting component 200 in the first direction. Thus, when the limiting component 200 and the flow channel component 100 are engaged, the position of the fluid handling component 300 and the flow channel component 100 in the first direction is also defined. A portion of the fluid handling component 300 is limited between the limiting component 200 and the flow channel component 100, thereby positioning the fluid handling component 300 within the flow channel component 100.
[0060] In detail Figure 6 , 8 As shown, the hole wall portion of the insertion portion 200a has a first stepped portion 200a1, and the first stepped portion 200a1 has a first stepped wall facing the flow channel component 100, that is, the first stepped wall is in Figure 6 The first step wall is the aforementioned limiting structure 200a11, which is set downwards from the center. Figure 7 In the middle, an annular boss is provided on the outer periphery of the second valve device 300B. The annular boss is a mating part 301. The end face of the mating part 301 on the side opposite to the flow channel component 100 is a limiting surface 301a. The limiting surface 301a is located in... Figure 6 The limiting surface 301a and the limiting structure 200a11 are positioned upwards, and their projections in the first direction at least partially overlap. It is understood that the limiting structure 200a11 is not limited to being formed by providing a first step portion 200a1 on the hole wall portion of the insertion hole portion 200a. For example, when the insertion hole portion 200a is a blind hole, the limiting structure 200a11 can also be the bottom wall of the insertion hole portion 200a. Furthermore, the limiting structure 200a11 can also be a portion of the bottom surface of the limiting member 200 facing the flow channel member 100.
[0061] The remaining valve devices are also equipped with mating parts 301 in the same manner as the second valve device 300B, and will not be described in detail here. During assembly, each valve device can first be installed to the corresponding interface part 101 of the flow channel component 100, and then the limiting component 200 is snapped into the flow channel component 100 from top to bottom. When the limiting component 200 and the flow channel component 100 move relative to each other in the first direction (i.e., the vertical direction), the second valve device 300B also passes through the insertion hole part 200a of the limiting component 200 from bottom to top. When the limiting component 200 and the flow channel component 100 are snapped into place, the limiting surface 301a of the mating part 301 and the limiting structure 200a11 of the limiting component 200 come into contact or abut against each other, and the valve device is thus limited between the flow channel component 100 and the limiting component 200.
[0062] It is understood that when the limiting component 200 and the flow channel component 100 are snapped together, the first step wall of the limiting structure 200a11 and the limiting surface 301a of the second valve device 300B are not limited to contact or abutment. They can also have a gap in the first direction. When the pressure fluid flows in the interface 101 corresponding to the valve device, the valve device will automatically move upward under the pressure of the fluid so that its limiting surface 301a abuts against the limiting structure 200a11 of the limiting component 200.
[0063] In addition, the first step portion 200a1 can be annular, which makes the limiting more reliable. Figure 8 In the middle, the two insertion portions 200a that cooperate with the fourth valve device 300D and the fifth valve device 300E have a first step portion 200a1 that is not annular, but has a notch, so as to avoid the lead wire components on the side of the fourth valve device 300D and the fifth valve device 300E (the fourth valve device 300D and the fifth valve device 300E are electronic expansion valves). The three insertion portions 200a that cooperate with the first valve device 300A, the second valve device 300B and the third valve device 300C have annular first step portions 200a1 and annular limiting structures 200a11.
[0064] Therefore, it can be seen that the integrated component in this embodiment, by setting the limiting component 200, can install the fluid processing component 300 onto the flow channel component 100 simply by snapping the limiting component 200 and the flow channel component 100 together. There is no need to assemble the fluid processing component 300 and the flow channel component 100 through relatively complicated methods such as threaded connection or welding. The assembly is simple, easy to operate, and can reduce installation costs.
[0065] The above-described method of forming a limiting structure 200a11 by providing a first stepped portion 200a1 on the hole wall portion of the insertion portion 200a is merely an example, and the structural form of the limiting structure 200a11 is obviously not limited to this. For example, it is also possible to provide a limiting structure on the side of the limiting member 200 away from the flow channel member 100, near the edge of the insertion portion 200a, so as to abut, contact, or have a certain gap with a part of the fluid processing member 300 in the first direction.
[0066] Please continue to combine Figure 2 and refer to Figures 9-11 understand, Figure 9 for Figure 3 A sectional view of the DD section; Figure 10 for Figure 9 Enlarged view of part E in the middle; Figure 11 for Figure 10 The three-dimensional structural diagram of the middle snap-fit part 201 is the first structure of the snap-fit part 201 in the embodiments of this application.
[0067] In this embodiment, the snap-fit portion 201 specifically includes a snap fastener 201A. The flow channel component 100 or the limiting component 200 may be provided with a snap-fit wall portion that snaps into the snap fastener 201A. In this embodiment, the snap fastener 201A is provided in the limiting component 200, and the first snap-fit wall portion 1031 is correspondingly provided in the flow channel component 100. The snap fastener 201A needs to snap into the first snap-fit wall portion 1031. Therefore, the snap fastener 201A includes a first snap-fit end 2011, which is a hook portion of the snap fastener 201A, to snap into the first snap-fit wall portion 1031 of the flow channel component 100. The first snap-fit end 2011 also includes a first snap-fit flange 20111 for more reliable snap-fit and fixation to the flow channel component 100. Figure 10 In the first engagement end 2011, the first engagement wall portion 1031 is engaged with the first engagement end 2011, thereby forming an engagement in the first direction. More specifically, the flow channel component 100 is provided with a groove portion 100a, the groove opening of the groove portion 100a is downward, and the downward-facing end face of the groove sidewall on one side is the first engagement wall portion 1031. The groove sidewall also has an inner wall portion extending in the first direction, and the first engagement flange 20111 is also engaged with the inner wall portion of the groove sidewall, thus achieving a double engagement, making the engagement more reliable.
[0068] Figure 11In the middle, the snap-fit part 201 includes a first connecting end 2012, a connecting part 2016, and a first snap-fit end 2011. The first connecting end 2012 and the first snap-fit end 2011 both extend in a direction perpendicular to the first direction. The connecting part 2016 extends in the first direction to connect the first snap-fit end 2011 and the first connecting end 2012. The entire snap-fit part 201 is generally a U-shaped block structure. The edge of the first snap-fit end 2011 is provided with a first snap-fit flange 20111. The first snap-fit flange 20111 protrudes from the first snap-fit end 2011 in a general direction and has a bevel, which can play a guiding role in the snap-fit process.
[0069] In this embodiment, the buckle 201A and the limiting component 200 are rotatably connected; for details, please refer to [further details]. Figure 10 , 11 ,as well as Figures 12-13 understand, Figure 12 for Figure 2 A schematic diagram of the middle limiting component 200 shows the side of the limiting component 200 away from the flow channel component 100, that is, it shows... Figure 8 On the opposite side of the middle limiting component 200; Figure 13 for Figure 12 Enlarged view of part F in the middle.
[0070] In this embodiment, the buckle 201A includes a first connecting end 2012 and a first engaging end 2011 for engaging with the flow channel component 100. The first connecting end 2012 is used for rotatably engaging with the limiting component 200. Specifically, as shown... Figure 12 , 13 As shown, the limiting component 200 is provided with a rotating shaft 202. The rotating shaft 202 and the limiting component 200 can be an integral structure, or they can be separately configured and then fixedly connected. Figure 10 As shown, the buckle 201A has a first groove portion 201a, which includes a first groove portion 201a1 and a second groove portion 201a2. The extension direction of the first groove portion 201a1 is parallel to the snapping direction of the buckle 201A, that is, it extends along the first direction. The extension direction of the second groove portion 201a2 is perpendicular to the extension direction of the first groove portion 201a1. The first end of the second groove portion 201a2 is connected to the lower end of the first groove portion 201a1. The second end of the second groove portion 201a2 penetrates the surface of the buckle 201A. Thus, the first groove portion 201a is specifically an L-shaped notch groove portion with one end open.
[0071] When assembling the buckle 201A to the limiting component 200, the second end of the second groove 201a2 of the buckle 201A can be aligned with the rotating shaft 202. Pushing the buckle 201A causes the rotating shaft 202 to engage with the second groove 201a2. That is, one open notch end of the second groove 201a2 serves as the inlet for the rotating shaft 202. After the rotating shaft 202 engages with the second groove 201a2, pulling the buckle 201A downwards causes the rotating shaft 202 to engage with the first groove 201a1. Simultaneously, the first engaging end 2011 at the lower end engages with the first engaging wall 1031, and the first engaging flange 20111 engages with the slot 100a. In other words, the rotating shaft 202 can slide from the second end of the second groove 201a2 into the first groove 201a1, thereby positioning the buckle 201A in a [position not specified]. Figure 10 As shown, the snap fastener 201A and the rotating shaft 202 are assembled in the following state: with the first snap-fit end 2011 in the snap-fit position, a portion of the rotating shaft 202 is located within the first groove 201a1 and engages with the first snap-fit flange 20111. This prevents the snap fastener 201A from disengaging from the limiting component 200 or the flow channel component 100 along the first direction or perpendicular to the first direction, thus achieving a relatively reliable assembly. This method of rotating the snap fastener 201A and the limiting component 200 together via the rotating shaft 202 is relatively simple and convenient for disassembling the snap fastener 201A.
[0072] Please continue to refer to this. Figure 13 At this time, the limiting component 200 is provided with a second groove portion 200b, which includes two oppositely arranged sidewall portions. Each sidewall portion is provided with a rotating shaft 202. The second groove portion 200b also has a notch facing the buckle 201A. The first connecting end 2012 of the buckle 201A can be pushed into the second groove portion 200b from the notch position, so that the rotating shaft 202 is engaged in the second groove portion 201a2 of the buckle 201A and finally engaged in the first groove portion 201a1. At this time, both opposite sides of the buckle 201A have a first groove portion 201a, and each first groove portion 201a and each rotating shaft 202 are correspondingly arranged, that is, both sides of each buckle 201A are engaged with the rotating shaft 202. In this way, the connection between the buckle 201A and the limiting component 200 is more reliable and the force is more balanced.
[0073] Obviously, the connection method between the buckle 201A and the limiting component 200 via the rotating shaft 202 is not limited to this. For example, one buckle 201A can be used with one rotating shaft 202, and the first connecting end 2012 of the buckle 201A is provided with a slot extending through both sides, so that it can be directly used with a rotating shaft 202. The above-mentioned method of using two rotating shafts 202 and one buckle 201A makes the connection and assembly of the first connecting end 2012 of the buckle 201A and the rotating shaft 202 more convenient, and the connection is reliable and not easy to detach.
[0074] Let's look again. Figures 14-16, Figure 14 This is a schematic diagram of the second structure of the snap-fit portion 201 in an embodiment of this application; Figure 15 for Figure 14 The main view; Figure 16 for Figure 14 A schematic diagram showing the engagement positions of the middle locking part 201, the limiting part 200, and the flow channel part 100.
[0075] In this embodiment, the snap-fit portion 201 is also a snap-fit 201A, but the snap-fit 201A includes a first snap-fit end 2011 and a second snap-fit end 2013. The first snap-fit end 2011 has the same structure as the first snap-fit end 2011 of the snap-fit portion 201A in the first structure described above, and it is also snap-fitted to the flow channel component 100. The snap-fit 201A of this structure is also roughly U-shaped. In the second structure, the snap-fit portion 201 and the limiting component 200 are no longer rotatably connected, but are also snap-fitted. The second snap-fit end 2013 is snap-fitted to the limiting component 200. The second snap-fit end 2013 has the same structure as the first snap-fit end 2011. The end edge of the second snap-fit end 2013 is also provided with a second snap-fit flange 20131, and the limiting component 200 is also provided with a slot portion 200d. Figure 16 In the middle, the slot of the slot portion 200d faces upward, and the end face of the slot sidewall on one side facing upward is the second snap-fit wall portion 2051. The slot sidewall also has an inner wall portion extending along the first direction. The second snap-fit flange 20131 also snaps with the inner wall portion of the slot sidewall, thus achieving double snap-fit, and the snap-fit is more reliable.
[0076] The snap-fit portion 201 in this embodiment can also adopt a third structure, such as... Figures 17-21 As shown, Figure 17 This is a schematic diagram of the integrated component in the second embodiment of this application; Figure 18 for Figure 17 A schematic diagram of the middle limiting component 200 shows the third structure of the snap-fit part 201; Figure 19 for Figure 17 Top view; Figure 20 for Figure 19 Central GG-direction sectional view; Figure 21 for Figure 20 Enlarged view of the H section.
[0077] In this embodiment, the snap-fit part 201 is also a snap-fit 201A. The snap-fit 201A includes a first snap-fit end 2011 and a second connecting end 2015. Similar to the above embodiment, the first snap-fit end 2011 is also used for snap-fit connection with the flow channel component 100. However, the snap-fit 201A and the limiting component 200 are not separate; the second connecting end 2015 of the snap-fit 201A and the limiting component 200 are an integral structure. Thus, when assembling the limiting component 200 and the flow channel component 100, only the limiting component 200 and the snap-fit part 201 need to be assembled. The limiting component 200 can be directly snap-fit connected to the flow channel component 100 along the first direction, simplifying the operation. However, compared to the above-mentioned snap-fit part 201, which is separate from the limiting component 200, it is more convenient for processing. Furthermore, as... Figure 21 As shown, unlike the U-shaped buckle 201A structure in the above embodiments, the buckle 201A in this embodiment is approximately L-shaped. The limiting component 200 can be provided with a third step portion, and the downward-facing wall of the third step portion is the first engaging wall portion 1031, which makes the engagement more convenient. Of course, in this embodiment, the first engaging end 2011 can also be provided with a first engaging flange to cooperate with the slot portion for engagement. In comparison, the above-mentioned U-shaped engaging portion 201 has a stronger deformation capacity, and the double engagement formed by providing the first engaging flange 20111 is easier to achieve and the engagement is more reliable.
[0078] Please continue to refer to this. Figures 22-26 As shown, Figure 22 This is a schematic diagram of the integrated component in the third embodiment of this application; Figure 23 for Figure 22 A schematic diagram of the middle limiting component 200 shows the fourth structure of the snap-fit part 201; Figure 24 for Figure 22 Top view; Figure 25 for Figure 24 Sectional view in the middle II direction; Figure 26 for Figure 25 Enlarged view of the J-section; Figure 27 for Figure 23 A magnified view of the K-section.
[0079] Unlike the snap-fit portion 201 in the above embodiment, which is a snap-fit 201A, the snap-fit portion 201 in this embodiment is a claw portion 201B. The claw portion 201B includes a plurality of claws 2014 arranged in a ring, such as... Figure 14As shown, the claw portion 201B includes four claws 2014. Each claw 2014 can also be understood as a latching structure. Each claw 2014 includes a claw root 20142 extending generally along a first direction and a claw claw portion 20141 located at the end of the claw root 20142. When subjected to external force, the multiple claws 2014 can retract and move closer together. The claw portion 201B can be directly mounted on the plate body 205, and can be an integral structure with the plate body 205, or it can be separate and then fixed. The flow channel component 100 may be provided with a locking portion 104 protruding towards the limiting component 200. The locking portion 104 is also a columnar structure with a hollow interior forming a hollow cavity 104a. The end of the locking portion 104 near the limiting component 200 has an annular flange 1041 extending radially inward. The outer diameter of the circumference of the multiple locking claws 104 of the locking claw portion 201B is larger than the inner diameter of the annular flange 1041. When the locking claw portion 201B is inserted into the through hole in the middle of the annular flange 1041, it will be squeezed and contracted. When the locking claw portion 201B is inserted into the hollow cavity 104a, the multiple locking claws 20141 of the locking claw portion 201B return to their original position, and the locking claws 20141 will engage with the side wall of the annular flange 1041 facing the hollow cavity 104a. The latch portion 201B is used as the latching part 201, ensuring reliable insertion and easy operation. The number of latch portions 201B can be set according to actual needs. Figure 23 The three claw parts 201B are shown.
[0080] In the above embodiments, the limiting component 200 includes a plate body 205, and an insertion hole 200a is disposed on the plate body 205, that is, the insertion hole 200a penetrates the plate body 205. The plate body 205 is disposed opposite to the flow channel component 100. In addition, the limiting component 200 also includes a support portion 204 extending from the plate body 205 to the flow channel component 100. When the snap-fit portion 201 is in the snap-fit state, the support portion 204 and the flow channel component 100 abut against each other, so that the plate body 205 and the flow channel component 100 have a gap in the first direction. In this way, space can be left on the plate body 205 and the limiting component 200 to avoid the interface portion 101.
[0081] like Figure 2 , 18As shown, the support portion 204 and the plate body 205 can be an integral structure, formed as a single piece. For example, the plate body 205 may have a recessed portion that partially faces the flow channel component 100, and this recessed portion serves as the support portion 204. In this case, the support portion 204 can be formed on the plate-shaped blank by stamping or stretching. Specifically, the support portion 204 may include a support sidewall portion 2041 and a support bottom wall portion 2042. One end of the support sidewall portion 2041 is connected to the plate body 205, and the support sidewall portion 2041 extends towards the flow channel component 100 in a first direction. The support bottom wall portion 2042 is connected to the end of the support sidewall portion 2041 near the flow channel component 100 and can abut against the surface of the flow channel component 100. In this way, the strength of the support portion 204 is relatively reliable.
[0082] Moreover, such as Figure 2 , 8 As shown, the support sidewall 2041 and support bottom wall 2042 of the support portion 204 form a groove structure with one side open. This support portion 204 has more reliable strength, and the number and distribution of the support portions 204 can be set according to the structure of the flow channel component 100 and actual needs. In some embodiments, the plate body 205 is generally rectangular, with support portions 204 provided at its two corners, and a support portion 204 also provided on the edge of a long side opposite to the two corners, for a total of three support portions 204.
[0083] Combination Figure 8 It is understood that in this embodiment, the limiting component 200 is further provided with a reinforcing part 203, which is specifically a triangular rib structure. The reinforcing part 203 connects the surface of the plate body 205 and the support part 204. One side of the reinforcing part 203 is connected to the support part 204, specifically extending along the support side wall 2041 to the support bottom wall 2042. The reinforcing part 203, the plate body 205, and the support part 204 can be an integral structure. The provision of the reinforcing part 203 makes the support part 204 stronger and the connection between the limiting component 200 and the flow channel component 100 more reliable.
[0084] Furthermore, in the above embodiments, when the latching part 201 is configured as a snap fastener 201A, the snap fastener 201A can be connected to the support part 204. For example... Figure 2 , 8 As shown in Figures 12 and 18, since the support portion 204 extends into the flow channel component 100, and the buckle 201A is disposed on the support portion 204, a portion of the buckle 201A can abut against the support portion 204, thereby making the buckle 201A have a stronger snap-fit bearing capacity. Figure 12 The second groove portion 200b is provided in the support bottom wall portion 2042. Figure 18 The second connecting end 2015 of the buckle 201A is directly integrated with the supporting bottom wall 2042.
[0085] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
