[0033] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0034] Please see Figures 1 to 7 This invention provides a description of an automotive fluid filler cap assembly and an automotive vehicle. The automotive fluid filler cap assembly includes a mounting structure, a ventilation plate 1, and a cap body 3. The ventilation plate 1 is located at the upper end of the mounting structure and has a filler port. The front side of the filler port extends to the edge of the ventilation plate 1. The cap body 3 overlaps the upper end of the filler port. The rear part of the cap body 3 has a rearwardly extending extension 9, which is inserted into the ventilation plate 1. The front part of the cap body 3 has a mounting hole located above the mounting structure and fixed to the mounting structure by means of a snap fastener 4.
[0035] This utility model provides an automotive filler cap assembly. Compared with the prior art, the mounting structure is located below the ventilation plate 1 and the cap body 3, supporting the ventilation plate 1 and the cap body 3. The filler port on the ventilation plate 1 extends forward to the front end of the ventilation plate 1. The cap body 3 overlaps the filler port and is flush with the ventilation plate 1 to cover the filler port. The rear end of the cap body 3 is inserted and limited to the ventilation plate 1 through the extension 9, and the front end of the cap body 3 is connected to the mounting structure with a male and female fastener 4. The extension 9 and the male and female fastener 4 cooperate to improve the stability and strength of the connection, avoiding the problem of breakage and failure of the connection structure between the cap body 3 of the filler port and the ventilation plate 1.
[0036] Optionally, the snap fastener 4 can be an existing snap fastener 4, such as a plastic snap fastener 4 piece with model number OGO3250037A. Figure 7 As shown, the male and female buckle 4 includes a male buckle 12 and a female buckle 11. First, the female buckle 11 is installed in the mounting hole and extends into the mounting structure. At this time, the male buckle 12 is in a free state. Then, the male buckle 12 is inserted into the female buckle 11. The male buckle 12 and the female buckle 11 are connected by threads or snap-fit. When the male buckle 12 is inserted into the female buckle 11, it will squeeze and deform the support leg 13 of the female buckle 11, thereby making the female buckle 11 connected and fastened to the mounting structure.
[0037] like Figure 7 As shown, the female buckle 11 has two legs 13, with their lower ends separated. The lower part of the male buckle 12 has a locking part that fits into the inner wall of the legs 13 of the female buckle 11. When the male buckle 12 is inserted into the female buckle 11, the locking part is positioned between the two legs 13. Then, the male buckle 12 is rotated, causing the locking part to rotate. The locking part contacts the inner wall of the legs 13 and causes the legs 13 to deform and expand outward, thus fixing the female buckle 11 to the mounting structure.
[0038] The front end of the cover plate body 3 is flush with the front end of the ventilation plate 1, and its rear end is arc-shaped and fits snugly against the rear end of the filling port.

The cover plate bracket 5 is located in the clearance notch and is connected to the installation plate 2. The cover plate body 3 is connected to the cover plate bracket 5.
[0040] The mounting structure for supporting the ventilation plate 1 and the cover body 3 consists of two parts. The mounting plate 2 supports the ventilation plate 1 and has a clearance notch at the filling port, with the open end of the clearance notch facing upwards. A cover bracket 5 is installed within the clearance notch. The cover bracket 5 is used only to connect and fix to the cover body 3 to support the cover body 3.
[0041] The cover plate bracket 5 is located within the clearance notch. The lower end of the cover plate bracket 5 is fixedly connected to the mounting plate 2. The cover plate bracket 5 extends upward to the opening of the clearance notch. The cover plate bracket 5 fits against the lower end face of the cover plate body 3. The snap fastener 4 connected to the cover plate body 3 is fixed to the cover plate bracket 5. The connection between the cover plate bracket 5 and the cover plate body 3 allows the cover plate body 3 to not only cooperate with the ventilation plate 1 but also be fixedly connected to the mounting plate 2, further improving the installation stability of the cover plate body 3.
[0042] Optionally, the cover plate bracket 5 is a sheet metal part. The cover plate bracket 5 has a through hole that is compatible with the snap fastener 4.
[0043] In some possible embodiments, please refer to Figure 1 and Figure 2 The cover plate bracket 5 is a U-shaped structure with the opening facing downwards. Both ends of the cover plate bracket 5 are connected to the mounting plate 2. The middle part of the cover plate bracket 5 has a through hole, which is coaxial with the mounting hole. The male and female buckles 4 connect the mounting hole and the through hole.
[0044] The cover plate bracket 5 has a U-shaped structure. Both ends of the cover plate bracket 5 extend downwards and have outwardly extending folded edges that fit against the edge of the clearance notch. The folded edges fit against the edge of the mounting plate 2 at the clearance notch and are welded or bolted to the mounting plate 2. The width direction of the folded edges is consistent with the thickness direction of the mounting plate 2. The middle part of the cover plate bracket 5 protrudes upwards to the lower end of the cover plate body 3. A longitudinal through hole is located in the middle of the cover plate bracket 5, which mates with the mounting hole for installing the male and female fasteners 4.
[0045] The cover plate bracket 5 has a U-shaped structure, and the lower part of the middle of the cover plate bracket 5 forms a receiving area, which accommodates the support legs 13 of the snap fastener 4. The cover plate bracket 5 provides support for the cover plate body 3 and installation space for the snap fastener 4, while improving the connection strength between the cover plate body 3 and the mounting plate 2.
[0046] In some possible embodiments, please refer to Figures 1 to 4 A shock-absorbing structure 7 is provided between the cover plate body 3 and the cover plate support 5; the upper end of the cover plate support 5 has a limiting groove, which is located in the circumferential direction of the through hole, and the shock-absorbing structure 7 is located in the limiting groove.
[0047] The upper end of the cover plate bracket 5 forms an annular limiting groove, which is filled with a shock-absorbing structure 7. The upper end of the shock-absorbing structure 7 protrudes from the opening of the limiting groove and is deformed by compression under the action of the snap fastener 4. The shock-absorbing structure 7 is located between the cover plate bracket 5 and the cover plate body 3 to achieve the purpose of sealing and shock absorption, reducing the vibration and abnormal noise of the cover plate body 3.
[0048] The shock-absorbing structure 7 can use shock-absorbing materials such as sealing rings, non-woven fabric, and sponge. The sealing ring is made of silicone.
[0049] In some possible embodiments, please refer to Figure 4 The front part of the cover plate body 3 has a recessed area 6 for fitting the male and female fasteners 4, and the mounting holes are located in the recessed area 6.
[0050] The recessed area 6 is used to accommodate the installation of the snap fastener 4 and the protruding area in the middle of the cover plate bracket 5. The recessed area 6 is circular. The cover plate body 3 forms a circular recessed area 6 at the front by bending or pressing. This area corresponds to the upwardly protruding middle area of the cover plate bracket 5. The lower end face of the recessed area 6 is in contact with the upper end face of the middle part of the cover plate bracket 5 or with the shock-absorbing structure 7 on the cover plate bracket 5. The groove formed at the upper end of the recessed area 6 is used to accommodate the upper part of the snap fastener 4.
[0051] In some possible embodiments, please refer to Figure 3 and Figure 5 The ventilation plate 1 is connected to a support part 8, which extends along the edge of the filling port toward the inside of the filling port. The upper end face of the support part 8 is attached to the lower end of the cover plate body 3, and the rear side of the support part 8 has a connection hole that is adapted to the extension part 9.
[0052] The support part 8 is located at the filling port. The support part 8 is connected to the body of the ventilation plate 1. The support part 8 extends along the edge of the filling port of the ventilation plate 1 toward the inside of the filling port. The support part 8 is lower than the ventilation plate 1. The upper end surface of the support part 8 forms a support surface, which is used to support the edge of the cover plate body 3.
[0053] During installation, the cover body 3 is first inserted into the connecting hole of the bearing part 8, and then the cover body 3 is placed on the upper surface of the bearing part 8, with the edge of the cover body 3 fitting against the edge of the filling port of the ventilation plate 1. The front part of the cover body 3 overlaps on the cover bracket 5; finally, the snap fastener 4 is installed. The cover body 3 is fixed by the cooperation of the rear extension part 9 and the snap fastener 4, which improves the connection strength and ensures the connection stability between the cover body 3, the ventilation plate 1, and the mounting plate 2.
[0054] In some possible embodiments, please refer to Figure 3 and Figure 5 The cross-section of the bearing part 8 is L-shaped. The bearing part 8 includes a longitudinal section and a transverse section. The longitudinal section is connected to the lower end face of the ventilation plate 1. The transverse section is connected to the lower end of the longitudinal section and extends towards the filling port. The cover plate body 3 is attached to the transverse section. The connecting hole is opened on the longitudinal section. The upper edge of the connecting hole is flush with the lower end face of the ventilation plate 1, and the lower edge of the connecting hole is flush with the upper end face of the transverse section.
[0055] The support portion 8 is connected to the ventilation plate 1 and extends into the filling port to form the support structure of the cover body 3. The trajectory of the support portion 8 extends along the edge of the filling port of the ventilation plate 1. The longitudinal section of the support portion 8 is connected to the ventilation plate 1, and the transverse section of the support portion 8 is perpendicularly connected to its longitudinal section and extends toward the side closer to the filling port. The transverse section and the longitudinal section cooperate to form a stepped support structure at the lower end of the ventilation plate 1. The upper end surface of the transverse section forms a support surface, and the cover body 3 is placed on the support surface. The upper end surface of the cover body 3 is flush with the upper end surface of the ventilation plate 1.
[0056] The connecting hole is opened in the longitudinal section of the bearing part 8, and it is inserted into the extension part 9 of the cover plate body 3 to limit the rear end of the cover plate body 3, avoid longitudinal vibration of the cover plate body 3 and improve the connection stability between the cover plate body 3 and the ventilation plate 1.
[0057] The transverse and longitudinal sections of the bearing portion 8 not only support the cover plate body 3 but also limit the extension portion 9 on the rear side of the cover plate body 3, thus achieving the limiting effect.
[0058] Since both the ventilation panel 1 and the cover body 3 have an upward U-shaped bend at the front, the front of the support portion 8 also bends upward to conform to the shape of the cover body 3. Optionally, the bend structure of the support portion 8 is Z-shaped, and the bend structure of the support portion 8 is connected to the bend structure of the ventilation panel 1. The front end of the support portion 8 is located inside the folded edge at the front end of the cover body 3.
[0059] In some possible embodiments, please refer to Figure 6 The extension 9 has two parts, and the two extensions 9 are spaced apart along the width direction of the cover body 3.
[0060] The cover plate body 3 has two spaced extensions 9. The extensions 9 and the snap fasteners 4 cooperate to form a three-point fixing structure, which is more stable than the two-point fixing structure.
[0061] Since the rear end of the cover plate body 3 is arc-shaped, the two extensions 9 are symmetrically arranged along the center line of the cover plate body 3. The two extensions 9 have the same structure. While ensuring the stable connection of the cover plate body 3 in the front-to-back direction, the stability of the cover plate body 3 in the left-to-right direction is also ensured, reducing the vibration of the cover plate body 3.
[0062] Specifically, the outer side of the extension 9 is wrapped with a cushioning structure 10. The cushioning structure 10 is made of non-woven fabric. The non-woven fabric is bonded to the outer side of the extension 9.
[0063] The upper end of the extension 9 is attached to the lower end of the ventilation plate 1, and its lower end is attached to the support part 8. The buffer structure 10 wraps around the outside of the extension 9 and extends into the connection hole together with the extension 9 to seal the gap between the extension 9 and the connection hole, thereby achieving a shock absorption effect and reducing abnormal noise caused by the vibration of the cover plate body 3.
[0064] Since the extension 9 and the connecting hole are plugged into each other, the buffer structure 10 cannot use easily damaged structures such as sponge.
[0065] Furthermore, the extension 9 includes an extension section and an inlet section. The inlet section is located on the side of the extension section away from the cover plate body 3, and the thickness of the inlet section gradually increases from its end toward the extension section. The lower end face of the inlet section is flush with the lower end face of the extension section, and the upper end face of the inlet section slopes upward from the free end toward the extension section. The inlet section facilitates the insertion of the extension 9 into the connection hole, and the extension section achieves the effect of insertion and limiting.
[0066] A vehicle is also provided, including the aforementioned vehicle filler cap assembly.
[0067] The present invention provides a vehicle, which, compared with the prior art, includes the above-mentioned vehicle filler cap assembly and has all the beneficial effects therein; the rear end of the filler cap assembly's cover body 3 is inserted and limited to the ventilation plate 1 through the extension 9, and the front end of the cover body 3 is connected to the mounting structure's male and female fastener 4; the extension 9 and the male and female fastener 4 cooperate to fix and improve the stability and strength of the connection, avoiding the problem of the connection structure between the filler cap body 3 and the ventilation plate 1 breaking and failing.
[0068] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
