Description

Technical Field

[0001] This utility model relates to a retaining structure. Background Technology

[0002] In recent years, research and development on lightweighting, which contributes to energy efficiency, has been ongoing to ensure access to affordable, reliable, sustainable, and advanced energy for more people. However, in the development of lightweighting, maintaining the lightweighting and structural strength of tubular structures remains a challenge.

[0003] In existing technologies, such as those disclosed in Japanese Patent Publication No. 4767912, an anti-detachment bracket (retainer) is used to hold the fuel pipe. The anti-detachment bracket houses a portion of the fuel pipe and a connector connected to the end of the fuel pipe, securing the fuel pipe and connector to prevent them from detaching. Considering weight reduction, it is envisioned that the entire bracket could be designed as a single component, housing the fuel pipe and connector through partial opening and closing of the structure. However, if the fuel pipe is inserted into the bracket in a misaligned state, the protrusions of the fuel pipe may exert pressure on a portion of the bracket, potentially causing the protrusions to embed in the wrong location, leading to bracket deformation and affecting structural strength. Therefore, it is necessary to structurally improve the bracket (retainer) to balance weight reduction and structural strength.

[0004] This invention aims to solve the aforementioned problem by achieving a balance between maintaining lightweight construction and structural strength. Furthermore, it contributes to energy efficiency. Utility Model Content

[0005] This invention provides a retaining structure that reliably retains the fuel pipe while balancing lightweight design and structural strength.

[0006] The retaining structure of this utility model includes: a fuel tube with a protrusion integrally formed at one end; a quick connector connecting the end of the fuel tube to other components; and a fuel tube retainer covering and retaining the quick connector and the end of the fuel tube, wherein the fuel tube retainer has an integrally formed first portion, a second portion, and a third portion located between the first portion and the second portion, the first portion receiving the protrusion of the fuel tube and the quick connector, and having an anti-detachment portion to prevent the fuel tube and the quick connector from detaching, the second portion extending in the direction opposite to the quick connector and covering a portion of the fuel tube, and the third portion receiving the fuel tube and having an inclined surface for the protrusion of the fuel tube to slidably displace toward the second portion.

[0007] In an embodiment of the present invention, the third portion has a compression space that accommodates a portion of the fuel pipe, the size of the compression space being the same as the size of the fuel pipe, and the inner wall of the compression space contacting at least a portion of the outer wall of the fuel pipe.

[0008] In an embodiment of this utility model, the second part has a passage space through which a portion of the fuel pipe passes, the size of the constricted space is smaller than the size of the passage space, and the wall thickness of the constricted space is greater than the wall thickness of the passage space.

[0009] In an embodiment of this utility model, the anti-detachment part includes: a cover component; and a hinge portion connecting the first part and the cover component, wherein the cover component can be opened and closed and fitted into the first part via the hinge portion.

[0010] In an embodiment of the present invention, the fuel pipe has a bend adjacent to the end, and the second portion covers the bend of the fuel pipe.

[0011] In an embodiment of the present invention, the fuel pipe holder further has an integrally formed fourth portion, which extends from the second portion in a direction opposite to the first portion and has an anti-rotation portion to prevent the fuel pipe from rotating.

[0012] Based on the above, in the retaining structure of this invention, the first, second, and third portions of the fuel pipe retainer are integrally formed, thus achieving lightweight design. The first portion accommodates the protrusion of the fuel pipe and the quick connector, and has an anti-dislodgement portion. The second portion extends in the opposite direction and covers a portion of the fuel pipe, thereby reliably retaining the quick connector and the fuel pipe. Furthermore, the third portion accommodates the fuel pipe and has an inclined surface that allows the protrusion of the fuel pipe to slide towards the second portion. Thus, even if the fuel pipe is inserted into the fuel pipe retainer in a misaligned state (e.g., the protrusion shifts towards the third portion), the protrusion of the fuel pipe can slide back to the second portion via the inclined surface of the third portion, preventing it from embedding into the third portion under force and causing deformation of the fuel pipe retainer. Therefore, the retaining structure of this invention reliably retains the fuel pipe while achieving both lightweight design and structural strength.

[0013] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below, and detailed descriptions are provided in conjunction with the accompanying drawings. Attached Figure Description

Figure 4B yes Figure 4A The diagram shown is a top view of the retaining structure. The following will be accompanied by... Figures 1 to 4B This invention describes the specific structure and installation method of the retaining structure 100 in this embodiment, but this invention is not limited thereto and can be adjusted according to requirements.

[0048] Please refer to Figures 1 to 2BIn this embodiment, the retaining structure 100 refers to a structure located near the fuel pipe 110 in the vehicle for retaining the fuel pipe 110. The retaining structure 100 includes the fuel pipe 110, the quick connector 120, and the fuel pipe retaining seat 130. The fuel pipe 110 has a protrusion 112 integrally formed at one end E1. The quick connector 120 connects the end E1 of the fuel pipe 110 to other components. The fuel pipe retaining seat 130 covers and retains the quick connector 120 and the end E1 of the fuel pipe 110. The fuel pipe retaining seat 130 has an integrally formed first portion 132, a second portion 134, and a third portion 136 located between the first portion 132 and the second portion 134. The first portion 132 accommodates the protrusion 112 of the fuel pipe 110 and the quick connector 120, and has an anti-detachment portion 132P to prevent the fuel pipe 110 and the quick connector 120 from detaching. The second portion 134 extends in the opposite direction to the quick connector 120 (i.e., toward the end E2) and covers a portion of the fuel pipe 110. The third portion 136 houses the fuel pipe 110 and has an inclined surface 137 that allows the protrusion 112 of the fuel pipe 110 to be slidably displaced toward the second portion 134.

[0049] Specifically, in this embodiment, as Figure 1 and Figure 2A As shown, the fuel pipe 110 is, for example, a pipe structure used in a vehicle, and has opposing ends E1 and E2. A protrusion 112 is integrally formed on end E1 of the fuel pipe 110, for example, configured as an annular protrusion surrounding the outer periphery of end E1 of the fuel pipe 110 (not a limitation). Furthermore, the quick connector 120 is, for example, a cylindrical connecting member that connects end E1 of the fuel pipe 110 to other components. Other components are exemplified here as another fuel pipe 140 (not a limitation). The other fuel pipe 140 is, for example, another pipe structure used in a vehicle. Thus, the end E1 of fuel pipe 110 and the end E3 of another fuel pipe 140 are inserted into the interior of quick connector 120 and connected, and engaged by the engaging portion 114 (e.g., another protrusion closer to the other fuel pipe 140 than the protrusion 112) formed on the end E1 of fuel pipe 110 and the engaged portion 142 (e.g., a notch) formed on the end E3 of the other fuel pipe 140. That is, quick connector 120 connects the fuel pipe 110 and the other fuel pipe 140 by covering the engaged ends E1 and E3 of the fuel pipe 110 from their outer peripheral sides. However, this invention does not limit the specific structure of fuel pipe 110, quick connector 120, and the other fuel pipe 140 (other components), as well as the connection means, etc., which can be adjusted according to requirements.

[0050] Additionally, in this embodiment, as Figure 1 and Figure 2A As shown, the fuel pipe holder 130 is, for example, a single component, and its support structure accommodates the fuel pipe 110 and the quick connector 120 through partial opening and closing. The fuel pipe holder 130 has a first portion 132, a third portion 136, and a second portion 134 sequentially formed on the fuel pipe 110 from end E1 towards end E2, to cover and hold the quick connector 120 and end E1 of the fuel pipe 110. For example, the fuel pipe 110 has a bend 116 adjacent to end E1. Thus, the end E1 of the fuel pipe 110 with the protrusion 112, the quick connector 120, and the end E3 of another fuel pipe 140 (which is another component) are preferably accommodated in the first portion 132. The portion of the fuel pipe 110 that is further towards end E2 than the protrusion 112 (e.g., the bend 116) is preferably covered by the second portion 134, and the portion of the fuel pipe 110 between the protrusion 112 and the bend 116 is preferably accommodated in the third portion 136. Furthermore, the first portion 132, the second portion 134, and the third portion 136 of the fuel pipe holder 130 are integrally formed, thereby achieving a lightweight design. However, this invention is not limited thereto and can be adjusted according to requirements.

[0051] Furthermore, in this embodiment, as Figure 1 and Figure 2A As shown, the first portion 132 accommodates the protrusion 112 of the fuel pipe 110 and the quick connector 120, and has an anti-dislodgement portion 132P. As an example, the first portion 132 is configured as a thin-walled cylindrical structure with a receiving space 132S for accommodating the protrusion 112 of the fuel pipe 110 and the quick connector 120, and has an anti-dislodgement portion 132P that can be opened and closed relative to the receiving space 132S. When the fuel pipe 110 and quick connector 120, which are engaged with each other, are inserted into the fuel pipe holder 130, the fuel pipe 110 should be positioned such that the end E1 with the protrusion 112 is aligned with the quick connector 120 in the receiving space 132S of the first portion 132. The anti-dislodgement portion 132P includes a cover member 150 and a hinge portion 160. The hinge portion 160 connects the first portion 132 and the cover member 150, and the cover member 150 is openably and closably fitted into the first portion 132 via the hinge portion 160. Therefore, when the cover component 150 is in the open state, the fuel pipe 110 and quick connector 120, which are engaged with each other, are inserted into the fuel pipe retainer 130, and the end E1 of the fuel pipe 110 with the protrusion 112 and the quick connector 120 are placed in the receiving space 132S of the first part 132 (as shown in the image). Figure 1 and Figure 2A As shown), the cover component 150 rotates via the hinge portion 160 (e.g., in...). Figure 1The first part 132 is fitted into the first portion 132 (by flipping it upwards) and covers the fuel pipe 110 and quick connector 120, thereby forming an anti-detachment portion 132P to prevent the fuel pipe 110 and quick connector 120 from falling off. Thus, by providing the anti-detachment portion 132P, the first portion 132 can reliably hold the quick connector 120 and the fuel pipe 110. However, this invention does not limit the specific structure of the first portion 132 and the anti-detachment portion 132P, etc., and they can be adjusted according to requirements.

[0052] Similarly, in this embodiment, as Figure 1 and Figure 2A As shown, the second portion 134 extends in the reverse direction (i.e., toward the end E2) and covers a portion of the fuel pipe 110. As an example, the second portion 134 is configured as a curved, thin-walled cylindrical structure with a passage space 134S for a portion of the fuel pipe 110 (e.g., the bend 116) to pass through. Therefore, when the fuel pipe 110 and quick connector 120, which are engaged with each other, are inserted into the fuel pipe retainer 130, and the end E1 of the fuel pipe 110 with the protrusion 112 and the quick connector 120 are placed in the receiving space 132S of the first portion 132 (e.g., ... Figure 1 and Figure 2A As shown, a portion of the fuel pipe 110 (e.g., the bend 116) can also be smoothly placed in the passage space 134S of the second portion 134, so that a portion of the fuel pipe 110 (e.g., the bend 116) is covered by the second portion 134. Furthermore, by providing the second portion 134 corresponding to the shape of the bend 116, the second portion 134 can reliably hold the fuel pipe 110. However, this invention does not limit the specific structure of the second portion 134, etc., and it can be adjusted according to requirements.

[0053] Furthermore, in this embodiment, such as Figures 1 to 2B As shown, the third portion 136 houses the fuel pipe 110 and has an inclined surface 137 that allows the protrusion 112 of the fuel pipe 110 to slide towards the second portion 134. As an example, the third portion 136 is configured as a thick-walled cylindrical structure with a constricted space 136S that houses a portion of the fuel pipe 110 (e.g., the portion between the protrusion 112 and the bend 116). The housing space 132S of the first portion 132, the constricted space 136S of the third portion 136, and the passage space 134S of the second portion 134 are interconnected. Therefore, when the fuel pipe 110 and the quick connector 120, which are engaged with each other, are inserted into the fuel pipe holder 130, and the end E1 of the fuel pipe 110 with the protrusion 112 and the quick connector 120 are placed in the housing space 132S of the first portion 132 (e.g.... Figure 1 and Figure 2AAs shown), a portion of the fuel pipe 110 (e.g., the portion between the protrusion 112 and the bend 116) can also be smoothly placed in the constricted space 136S of the third part 136, so that a portion of the fuel pipe 110 (e.g., the portion between the protrusion 112 and the bend 116) is received by the third part 136.

[0054] Furthermore, in this embodiment, as Figure 1 and Figure 2A As shown, as an example, the size of the compression space 136S of the third portion 136 (e.g., the inner circumferential diameter) is the same as the size of the fuel pipe 110 (e.g., the pipe diameter), and the inner wall of the compression space 136S contacts at least a portion of the outer wall of the fuel pipe 110. That is, the compression space 136S of the third portion 136 preferably accommodates a portion of the fuel pipe 110 (e.g., the portion between the protrusion 112 and the bend 116) without gaps, but gaps due to manufacturing tolerances are allowed. In this way, the third portion 136, formed with the compression space 136S, can reliably hold the fuel pipe 110 without providing a structure like the anti-detachment portion 132P of the first portion 132. Preferably, the size of the constricted space 136S of the third portion 136 (e.g., the inner circumferential diameter) is smaller than the size of the passage space 134S of the second portion 134 (e.g., the inner circumferential diameter), and the wall thickness of the constricted space 136S of the third portion 136 (thick-walled cylindrical structure) is greater than the wall thickness of the passage space 134S of the second portion 134 (thin-walled cylindrical structure). Thus, when the third portion 136 and the second portion 134 have continuously extending outer circumferential surfaces (e.g., the same outer circumferential diameter), a constricted space 136S is formed inwardly in the third portion 136. This allows the third portion 136 to accommodate a portion of the fuel pipe 110 without gaps, reliably retain the fuel pipe 110 through the thick-walled structure, and easily form the inclined surface 137. However, this invention does not limit the specific structure of the third portion 136, etc., and it can be adjusted according to requirements.

[0055] Therefore, in this embodiment, as Figure 1 and Figure 2AAs shown, the inclined surface 137 of the third portion 136 spans the first portion 132 and the second portion 134, and is provided on the surface side of the constriction space 136S, gradually sloping from the first portion 132 toward the second portion 134. For example, the side of the third portion 136 corresponding to the first portion 132 is thicker than the side of the third portion 136 corresponding to the second portion 134, so that the surface side of the third portion 136 forms an inclined surface 137 that gradually decreases in thickness from the first portion 132 toward the second portion 134. Therefore, when the fuel pipe 110 and the quick connector 120, which are engaged with each other, are inserted into the fuel pipe holder 130, but the end E1 of the fuel pipe 110 with the protrusion 112 is not aligned with the quick connector 120 in the receiving space 132S of the first portion 132, as... Figure 3A and Figure 3B As shown, the fuel pipe 110 is misaligned relative to the fuel pipe holder 130 (for example, the protrusion 112 is offset towards the third portion 136 relative to the first portion 132). If the fuel pipe 110 is inserted into the fuel pipe holder 130 in the misaligned state, the portion of the fuel pipe 110 with the protrusion 112 cannot be accommodated due to the small size of the constriction space 136S of the third portion 136. The portion of the fuel pipe 110 with the protrusion 112 is blocked on the surface side of the constriction space 136S, i.e., the inclined surface 137, by the third portion 136, which is composed of a thick-walled structure, and will not be embedded in the third portion 136 due to force. Furthermore, since the third portion 136 is provided with an inclined surface 137, even when the fuel pipe 110 is inserted into the fuel pipe holder 130 in a misaligned state (e.g., the protrusion 112 is offset towards the third portion 136), the protrusion 112 of the fuel pipe 110 can be slidably displaced to the second portion 134 via the inclined surface 137 of the third portion 136 (e.g., ...). Figure 4A and Figure 4B As shown), the fuel pipe holder 130 will not deform due to being embedded in the third part 136 under force.

[0056] Preferably, in this embodiment, as Figure 4A and Figure 4BAs shown, even if the protrusion 112 of the fuel pipe 110 slides to the second portion 134 via the inclined surface 137, since the quick connector 120 and the like are not housed in the receiving space 132S of the first portion 132 due to misalignment, or more preferably, the quick connector 120 is blocked on the surface side of the constriction space 136S of the third portion 136, i.e., the inclined surface 137, the protrusion 112 will not be embedded in the passage space 134S of the second portion 134. In other words, in the state of misalignment of the fuel pipe 110, the fuel pipe 110 and the quick connector 120 are guided by the inclined surface 137 to avoid improper installation and will not damage the fuel pipe retainer 130, thereby ensuring the structural strength of the retaining structure 100 during installation. After the protrusion 112 of the misaligned fuel pipe 110 is slidably displaced towards the second portion 134 via the inclined surface 137, the fuel pipe 110 and the quick connector 120 are blocked on the surface side of the constriction space 136S of the third portion 136, i.e., the inclined surface 137, and are not improperly embedded in the fuel pipe holder 130. Therefore, the fuel pipe 110 can be easily reinstalled. For example, the fuel pipe 110 can be repositioned such that the end E1 with the protrusion 112 is aligned with the quick connector 120 in the receiving space 132S of the first portion 132. It can be repeatedly adjusted before correct installation without damaging the fuel pipe holder 130. Accordingly, the retaining structure 100 can reliably retain the fuel pipe 110 while taking into account both lightweight and structural strength.

[0057] Therefore, in this embodiment, as Figures 1 to 2B As shown, the fuel pipe holder 130 also has an integrally formed fourth portion 138, which extends from the second portion 134 in a direction opposite to the first portion 132 (i.e., toward the end E2), and has an anti-rotation portion 138P to prevent the fuel pipe 110 from rotating. For example, the first portion 132 is provided with an anti-rotation space 138S for accommodating the fuel pipe 110 and is configured as a thin-walled cylindrical structure, and has an anti-rotation portion 138P that can be opened and closed relative to the anti-rotation space 138S. The anti-rotation portion 138P includes a cover portion 170 and a shaft portion 180, the shaft portion 180 connecting the fourth portion 138 and the cover portion 170, and the cover portion 170 being openably and closably fitted into the fourth portion 138 via the shaft portion 180. Therefore, when the fuel pipe 110 is placed in the anti-rotation space 138S of the fourth portion 138 with the cover portion 170 open (e.g., ...), ... Figure 1 and Figure 2A As shown), the cover 170 can rotate via the shaft 180 (e.g., in...). Figure 1The fuel pipe 110 is fitted into the fourth part 138 (flipped upwards) and covers the fuel pipe 110 placed in the anti-rotation space 138S, thereby forming an anti-rotation part 138P to prevent the fuel pipe 110 from rotating. Thus, by providing the anti-rotation part 138P, the fourth part 138 can more reliably hold the fuel pipe 110. However, this invention does not limit the specific structure of the fourth part 138 and the anti-rotation part 138P, etc., which can be adjusted according to requirements.

[0058] Furthermore, in this embodiment, such as Figures 1 to 2B As shown, in the fuel pipe retainer 130, not only are the first portion 132, the second portion 134, the third portion 136, and the fourth portion 138 integrally formed, but preferably, the anti-detachment portion 132P and the anti-rotation portion 138P are also integrally formed with the aforementioned portions, meaning the entire fuel pipe retainer 130 is configured as a single component. In this way, the retaining structure 100 can further achieve structural lightweighting and improve versatility. However, this invention does not limit the specific structure of the fuel pipe retainer 130, which can be adjusted according to requirements.

[0059] In summary, in the retaining structure of this invention, the first, second, and third portions of the fuel pipe retainer are integrally formed, thus achieving lightweight design. The first portion accommodates the protrusion of the fuel pipe and the quick connector and has an anti-dislodgement portion. The second portion extends in the opposite direction and covers a portion of the fuel pipe, thereby reliably retaining the quick connector and the fuel pipe. Furthermore, the third portion accommodates the fuel pipe and has an inclined surface that allows the protrusion of the fuel pipe to slide towards the second portion. Thus, even if the fuel pipe is inserted into the fuel pipe retainer in a misaligned state (e.g., the protrusion shifts towards the third portion), the protrusion of the fuel pipe can slide back to the second portion via the inclined surface of the third portion, preventing it from embedding into the third portion under force and causing deformation of the fuel pipe retainer. Preferably, the fuel pipe retainer also has an integrally formed fourth portion, which extends in the opposite direction from the second portion and has an anti-rotation portion, thereby further reliably retaining the fuel pipe. Accordingly, the retaining structure of this invention reliably retains the fuel pipe while achieving both lightweight design and structural strength.
