Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a hard plastic base for a car fuel filler door. Background Technology

[0002] As a crucial component of both the vehicle's appearance and function, the reliability of the fuel filler door's base structure directly impacts the user experience and perceived quality. The fuel filler door base not only needs to provide a stable mounting foundation for the door but also must effectively protect the connecting lines and moving parts.

[0003] Traditional accelerator pedal bases are mostly made of a single material, with soft rubber bases being widely used due to their elasticity. These bases are typically fixed directly to the vehicle body sheet metal via their snap-fit ​​structure or adhesive method. The accelerator pedal pivot or handle is installed by passing it through pre-drilled holes in the base, relying on the material's flexibility to achieve basic buffering and limiting functions.

[0004] However, in actual use, due to the softness of the overall material of the soft rubber base, after being subjected to the torque and vibration of the frequent opening and closing of the fuel filler door for a long time, it is prone to plastic deformation or permanent fatigue, resulting in loosening of the filler door, abnormal noise, or even failure to close properly. In addition, the single soft rubber material does not provide sufficient protection for the internal bends or cables, and friction and wear are easily generated between the parts in the vibration environment of vehicle driving. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a hard plastic base for a car fuel filler door, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a hard rubber base for a car fuel filler door, including a first protective sleeve, a top ring fixed to the top of the first protective sleeve, a pad fixed to the bottom of one side of the inner wall of the top ring, a connecting hole through the top of the pad, a rectangular groove through the inner wall of the first protective sleeve, and a lower protective sleeve and an upper protective sleeve fixed to the outer wall of the rectangular groove.

[0008] Furthermore, a second limiting hook rod is fixed at the bottom of the outer wall of the top ring near the first protective sleeve. Multiple second limiting hook rods are provided, and the second limiting hook rods are arranged in a J-shape.

[0009] Furthermore, a connecting groove is provided at the bottom of the outer wall of the first protective sleeve, and the depth of the connecting groove is 3-6 mm.

[0010] Furthermore, a first limiting hook rod is fixed to the middle part of the first protective sleeve near the connection hole and the bottom part of the outer wall of the pad. The first limiting hook rod is L-shaped and the openings of the two first limiting hook rods are arranged in opposite directions.

[0011] Furthermore, the outer walls of the lower and upper protective sleeves are arc-shaped, and the interiors of the lower and upper protective sleeves are hollow. The distance between the lower and upper protective sleeves is 2-4 mm.

[0012] Furthermore, insert rods are fixed on both sides of the outer wall of the upper protective sleeve, and limit sleeves are fixed on both sides of the outer wall of the lower protective sleeve. Limit blocks are fixed on opposite sides of the two insert rods, and one side of the limit block is inclined. The limit block and the limit sleeve are used together.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0014] This application uses multiple J-shaped second limiting hooks and connecting grooves on the outer wall of the top ring to connect with the soft rubber base, thus constraining the edge of the soft rubber base. Two L-shaped first limiting hooks with opposite openings limit the rubber strip of the mounting ring used to connect the connecting hole of the soft rubber base, preventing it from loosening and hanging. The bent handle of the refueling valve is passed through the rectangular groove, and the lower and upper protective sleeves cover the upper and lower sides of the bent handle, respectively. The limiting block at the bottom of the insertion rod is inserted into the limiting sleeve. The inclined limiting block can better enter the limiting sleeve. After insertion, the top of the limiting block is locked with the bottom of the limiting sleeve, effectively preventing the protective sleeve from opening due to vibration, significantly improving assembly stability, component protection, and reliability.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0025] This application discloses a hard plastic base for a car fuel filler door, including a first protective sleeve 4, a top ring 1 fixed to the top of the first protective sleeve 4, a pad 2 fixed to the bottom of one side of the inner wall of the top ring 1, a connecting hole 3 through the top of the pad 2, a rectangular groove 6 through the inner wall of the first protective sleeve 4, and a lower protective sleeve 7 and an upper protective sleeve 8 fixed to the outer wall of the rectangular groove 6.

[0026] Reference Appendix Figure 3 and 5 The bottom of the outer wall of the top ring 1 is fixed with a second limiting hook rod 10 near the first protective sleeve 4. There are multiple second limiting hook rods 10, and the second limiting hook rods 10 are arranged in a J-shape. By locking the ring at the top of the soft rubber base inside the multiple second limiting hook rods 10, the initial connection between the soft rubber base and the hard rubber base is achieved.

[0027] Reference Appendix Figure 1 The bottom of the outer wall of the first protective sleeve 4 is provided with a connecting groove 5. The depth of the connecting groove 5 is 3-6MM. The connecting groove 5 is used to snap onto the top edge of the soft rubber base or to stick it with glue.

[0028] Reference Appendix Figure 2The first protective sleeve 4 is fixed with a first limiting hook rod 9 on the middle part of the side near the connecting hole 3 and on the bottom side of the outer wall of the pad 2. The first limiting hook rod 9 is L-shaped and the openings of the two first limiting hook rods 9 are opposite. The rubber strip of the soft rubber base used to connect the mounting ring of the connecting hole 3 can be limited by the two first limiting hook rods 9. After the connecting hole 3 is connected to the connector of the soft rubber base, the rubber strip will not hang.

[0029] Reference Appendix Figure 3 and 4 The lower protective sleeve 7 and the upper protective sleeve 8 have arc-shaped outer walls and hollow interiors. The spacing between the lower protective sleeve 7 and the upper protective sleeve 8 is 2-4 mm. The arc-shaped lower protective sleeve 7 and the upper protective sleeve 8 can better fit the curved handle of the fuel filler door. During installation, the curved handle of the fuel filler door can be passed through the rectangular groove 6, and the lower protective sleeve 7 and the upper protective sleeve 8 cover the upper and lower sides of the curved handle, respectively.

[0030] Reference Appendix Figure 4 The upper protective sleeve 8 has two fixed insert rods 11 on both sides of its outer wall, and the lower protective sleeve 7 has two fixed limit sleeves 13 on both sides of its outer wall. The two insert rods 11 have two fixed limit blocks 12 on opposite sides. The limit blocks 12 are set at an angle. The limit blocks 12 and the limit sleeves 13 are used together. After the bent handle is installed, the limit block 12 at the bottom of the insert rod 11 is inserted into the limit sleeve 13. The angled limit block 12 can enter the limit sleeve 13 better. After insertion, the top of the limit block 12 is stuck to the bottom of the limit sleeve 13 to prevent the upper protective sleeve 8 and the lower protective sleeve 7 from separating.

[0031] The workflow of this utility model is as follows:

[0032] First, the ring at the top of the soft rubber base is inserted into the interior of multiple second limiting hooks 10 to achieve a preliminary connection between the soft rubber base and the hard rubber base. Then, the top edge of the soft rubber base is embedded into the connecting groove 5 at the bottom of the outer wall of the first protective sleeve 4. The 3-6mm deep connecting groove ensures a tight fit at the edge. Next, the mounting ring rubber strip on the soft rubber base used to connect the connecting hole 3 is inserted into the two L-shaped first limiting hooks 9 with opposite openings to ensure that the rubber strip does not droop after the connecting hole 3 is connected to the connector of the soft rubber base. Then, the curved handle of the fuel filler door is passed through the rectangular groove 6 so that the arc-shaped lower protective sleeve 7 and upper protective sleeve 8 cover the upper and lower sides of the curved handle to form protection. Finally, the insert rods 11 on both sides of the upper protective sleeve 8 are inserted into the limiting sleeves 13 on both sides of the lower protective sleeve 7. After the inclined limiting block 12 on the insert rod 11 smoothly enters the limiting sleeve 13, the top of the limiting block 12 and the bottom of the limiting sleeve 13 form a locking connection to prevent the upper protective sleeve 8 and the lower protective sleeve 7 from separating, thus completing the entire installation process.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
