Description

Technical Field

[0001] This utility model relates to the field of panel technology, specifically to a small panel for a car fuel filler door. Background Technology

[0002] The fuel tank door industry can be traced back to the 1970s. At that time, it mainly relied on metal stamping technology for manufacturing. The products had a simple structure and function, and could only meet the basic needs of covering the fuel filler neck. The continuous investment of major global automakers in energy conservation and emission reduction has prompted continuous optimization in the selection of materials for fuel filler door panels, with more high-strength plastics and composite materials being used.

[0003] In existing technologies, most automotive fuel filler door panels are manually opened. The connection between the existing fuel filler door panel and the fuel inlet on the vehicle body is sealed with a rubber strip. In rainy weather or when washing the car, this prevents rainwater from seeping into the fuel inlet area. However, there are some drawbacks: the rubber strip is mostly made of elastic rubber material, relying on its own elastic deformation to fill gaps. When the assembly gap between the fuel inlet and the fuel filler door panel is too large, the elastic stretch of the rubber strip cannot completely fill the gap, resulting in the rubber strip not being able to form a tight fit with the inner wall of the fuel inlet. This leads to poor sealing performance in preventing rainwater from seeping into the fuel inlet area. Conversely, if the assembly gap is too small, the rubber strip will lose its normal elastic deformation space due to excessive compression, which may make it difficult for the fuel filler door panel to close smoothly. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a small door panel for automobile refueling, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a car refueling door panel, including a refueling door panel body and a first sealing strip and a second sealing strip sleeved on the refueling door panel body. The refueling door panel body has mounting holes on the outer periphery of the outer periphery. An adaptive component is provided on the outer periphery of the refueling door panel body. The adaptive component is used to elastically stretch and tighten the first sealing strip and the second sealing strip to fit tightly against the inner edge of the car refueling panel inlet.

[0007] The adaptive component includes a telescopic contact strip and a fixed sleeve. The outer wall of the fixed sleeve is fixedly fitted inside the mounting hole, and a sealing cap is fixedly installed at the upper end of the fixed sleeve.

[0008] Furthermore, a compression spring is fixedly installed at the lower end of the telescopic contact strip, a movable piece is fixedly installed at the upper end of the compression spring, a telescopic guide rod is fixedly installed at the upper end of the movable piece, and a telescopic hole is opened inside the fixed sleeve.

[0009] Furthermore, the movable piece is slidably fitted inside the telescopic hole of the fixed sleeve, the telescopic guide rod is slidably fitted inside the closed cover, and the upper end of the telescopic guide rod is fixedly installed at the lower end of the telescopic contact strip.

[0010] Furthermore, the upper end of the telescopic contact strip is in close contact with the inside of the first and second sealing strips. The telescopic contact strip has the same structural shape as the first sealing strip at both ends of the refueling door panel body, and the telescopic contact strip has the same structural shape as the second sealing strip at the upper and lower ends of the refueling door panel body.

[0011] Furthermore, both the first and second sealing strips have internal grooves, and the telescopic contact strips are located inside the internal grooves.

[0012] Furthermore, a fixing slot is provided inside one side of the refueling door panel body, and a fastening block is fixedly sleeved inside the fixing slot. A connection port is provided on one side of the first sealing strip and the second sealing strip, and one end of the fastening block is connected to the inside of the connection port by heat fusion.

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

[0014] 1. This utility model, through the compression spring, telescopic guide rod, and telescopic contact plate of the adaptive component, can automatically compensate for the assembly gap error between the fuel filler inlet and the fuel filler door panel of the vehicle body through the cooperation of the compression spring and the telescopic structure. This ensures that the fuel filler door panel fits tightly against the inner wall of the fuel filler inlet of the vehicle body, effectively preventing dust, moisture, and impurities from entering the fuel filler inlet. When the assembly gap between the fuel filler inlet and the fuel filler door panel is too small, the compression spring, telescopic guide rod, and telescopic contact plate prevent the fuel filler door panel from being unable to cover the fuel filler inlet of the vehicle body smoothly.

[0015] 2. At the same time, the fixing slots and fastening blocks of the fuel filler door panel ensure that the first and second sealing strips will not fall off the fuel filler door panel body, thereby improving the sealing performance of the first and second sealing strips on the fuel filler door panel.

[0024] 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.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Reference Figures 1 to 6This is the first embodiment of the present invention, which discloses a car refueling door panel, including a refueling door panel body 1 and a first sealing strip 2 and a second sealing strip 3 sleeved on the refueling door panel body 1. The refueling door panel body 1 has mounting holes 11 on the inner side of the outer periphery. The refueling door panel body 1 has an adaptive component 6 on the outer periphery. The adaptive component 6 is used to elastically stretch and tighten the first sealing strip 2 and the second sealing strip 3 to fit tightly against the inner edge of the car refueling panel inlet. The car refueling door panel is common in the prior art. It uses ABS plastic, which has excellent impact strength and rigidity and can withstand collisions and squeezing in daily use. It will not be described in detail here. The first sealing strip 2 and the second sealing strip 3 are usually made of ethylene propylene diene monomer (EPDM) rubber or EPDM composite material modified with graphite or silane.

[0027] The adaptive component 6 includes a telescopic contact strip 61 and a fixed sleeve 62. The outer wall of the fixed sleeve 62 is fixedly fitted inside the mounting hole 11. The outer wall of the fixed sleeve 62 is coated with sealant and aligned with the mounting hole 11 of the fuel filler door panel body 1. An interference fit or bolt fastening method is used to make the fixed sleeve 62 and the mounting hole 11 form a rigid connection. A sealing cover 67 is fixedly installed on the upper end of the fixed sleeve 62. A compression spring 64 is fixedly installed on the lower end of the telescopic contact strip 61. A movable piece 65 is fixedly installed on the upper end of the compression spring 64. The compression spring 64 is inserted from the lower end of the fixed sleeve 62. Then the movable piece 65 is slidably fitted into the telescopic hole 63. A telescopic guide rod 66 is fixedly installed on the upper end of the movable piece 65. The telescopic hole 63 is opened inside the fixed sleeve 62.

[0028] The movable piece 65 is slidably fitted inside the telescopic hole 63 of the fixed sleeve 62, and the telescopic guide rod 66 is slidably fitted inside the closed cover 67. The upper end of the telescopic guide rod 66 is fixedly installed on the lower end of the telescopic contact strip 61. The upper end of the telescopic contact strip 61 is in close contact with the inside of the first sealing strip 2 and the second sealing strip 3. The telescopic contact strip 61 has the same structural shape as the first sealing strip 2 at both ends of the refueling door panel body 1, and the telescopic contact strip 61 has the same structural shape as the second sealing strip 3 at the upper and lower ends of the refueling door panel body 1. The first sealing strip 2 and the second sealing strip 3 are both provided with inner grooves 5. The compression spring 64 inside the telescopic contact strip 61 is in a pre-compressed state. The elastic force is transmitted to the telescopic contact strip 61 through the movable piece 65 and the telescopic guide rod 66, so that it always has an upward thrust. The telescopic contact strip 61 is located inside the inner groove 5.

[0029] In use, when the refueling door panel is closed over the refueling inlet of the car body, the outer sides of the first sealing strip 2 and the second sealing strip 3 come into contact with the inner wall of the refueling inlet. During the closing process, the first sealing strip 2 and the second sealing strip 3 are initially compressed and contracted, and the telescopic contact strip 61 is compressed, further driving the telescopic contact strip 61 to move downward. This, in turn, causes the telescopic guide rod 66 and the movable piece 65 to contract and move downward inside the fixed sleeve 62, compressing the compression spring 64 downward. The refueling door panel is then completely closed over the inner wall of the refueling inlet of the car body. When the refueling inlet of the car body is in contact with the refueling inlet... When the assembly gap between the small door panels is too large, the compression spring 64 will cause the movable piece 65 and the telescopic guide rod 66 to move upward, which in turn will cause the telescopic contact strip 61 to move upward, thereby extending the first sealing strip 2 and the second sealing strip 3. This allows the first sealing strip 2 and the second sealing strip 3 to be tightly pressed against the inner wall of the fuel filler inlet of the car body. When the assembly gap between the fuel filler inlet of the car body and the fuel filler door panel is too small, the compression spring 64, the telescopic guide rod and the telescopic contact piece will prevent the fuel filler door panel from being unable to cover the fuel filler inlet of the car body smoothly.

[0030] Example 2:

[0031] Reference Figure 2 and Figure 3 , Figure 5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a fixing groove 12 is provided inside one side of the refueling door panel body 1. A fixing groove 12 of a preset size is machined inside one side of the refueling door panel body 1 to ensure that the groove size matches the fastening block 4. The fastening block 4 is fixedly sleeved inside the fixing groove 12. A connection port 21 is provided on one side of the first sealing strip 2 and the second sealing strip 3. One end of the fastening block 4 is connected to the inside of the connection port 21 by heat fusion.

[0032] In use, the fastening block 4 forms a molecular-level bond with the connection port 21 of the sealing strip through a heat-melting method. The fastening block 4 is made of plastic material and is fixed by the fixing slot 12, which provides a fixed base for the fastening block 4, ensuring that the first sealing strip 2 and the second sealing strip 3 will not fall off the fuel filler door panel body 1, thereby improving the sealing performance of the first sealing strip 2 and the second sealing strip 3 on the fuel filler door panel.

[0033] The remaining structure is the same as that in Example 1.

[0034] 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.
