Description

Technical Field

[0001] The invention relates to the technical field of automobile parts, and in particular to an automobile cover structure, a working method and an automobile. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The common flap structure on cars on the market is the gooseneck flap, which is opened and closed by the rotation of the gooseneck, specifically flipping up and opening sideways. The maximum opening angle of the flap outer panel is 90 degrees, perpendicular to the side outer panel. When the car is refueling or charging, the flap is opened, and the flap outer panel structure completely protrudes from the entire car body.

[0004] At present, four-link type covers have appeared and are gradually increasing. They are basically used in larger charging cover. Specifically, they can be divided into four-link downward sliding and four-link forward sliding. Due to the structural characteristics of the four-link, the opening and closing of the cover is relatively flexible, and the outer panel of the cover can be opened in parallel with the outer panel of the side panel.

[0005] Since the outer panel of the gooseneck cover is usually made of plastic, especially the charging port cover has a larger outer panel, when the cover is opened, people or other moving objects passing by are very likely to break the hinge of the cover.

[0006] The four-link mouth cover structure design is composed of multiple rods, which is relatively complex, increasing the difficulty and cost of the manufacturing process, and usually makes the mouth cover heavier and larger in size. Summary of the invention

[0007] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a vehicle cover structure, a working method and a vehicle, which are improved on the basis of the current gooseneck cover structure and overcome the defects of the current gooseneck cover structure and four-link cover structure.

[0030] Example 1

[0031] This embodiment provides a car cover structure, such as Figure 1-Figure 3As shown, a plate and a curved arm 2, a first rotating shaft 3 is provided on the outer side of one end of the mouth box 1, the first rotating shaft 3 is rotatably connected to one end of the curved arm 2, and the other end of the curved arm 2 is connected to the outer plate of the mouth cover, the curved arm 2 adopts a gooseneck shape, the curved arm 2 passes through the mouth box 1 through an opening provided on the side box wall of one side of the mouth box 1, one end of the curved arm 2 is rotatably connected to the first rotating shaft 3, and the other end of the curved arm 2 is connected to the outer plate of the mouth cover. Specifically, a connecting block 4 is provided on the outer side surface of one side of the mouth box 1, and a first rotating shaft 3 is provided on the top of the connecting block 4. The first rotating shaft 3 is a smooth shaft, and a sleeve is provided on the end of the curved arm 2 for connecting with the first rotating shaft 3, which is sleeved on the outer periphery of the first rotating shaft 3 and rotatably connected to the first rotating shaft 3, and the curved arm 2 can rotate around the first rotating shaft 3. Since the first rotating shaft 3 is a smooth shaft, the friction between the curved arm 2 and the first rotating shaft 3 is very small. There is an actuator 5, which can be made of existing technology and is used to cooperate with the outer panel of the mouth cover so that the outer panel of the mouth cover can be locked and fixed in the closed state. The outer panel of the mouth cover includes a plate body 6 and a protrusion 7 arranged on the inner side of the plate body. The protrusion 7 is made of plastic material, and the plate body 6 is made of the same sheet metal material as the vehicle body material. The protrusion 7 is connected to the end of the curved arm 2 through a connecting member 8. The connecting member 8 adopts a block structure, and its end with a larger area is connected to one end on the inner side of the protrusion 7, and the end with a smaller area is connected to the end of the curved arm 2. The curved arm 2 can rotate around the first rotating shaft 3, thereby realizing the switching of the open and closed states of the open side of the mouth box 1. When the outer panel of the mouth cover closes the open side of the mouth box 1, the outer panel of the mouth cover can cooperate with the contacts of the actuator 5, thereby triggering the actuator 5 to work and lock the outer panel of the mouth cover.

[0032] The above technology can adopt the existing automobile gooseneck cover technology, and its further technical details are not described in detail here.

[0033] In a traditional gooseneck automobile hatch structure, the connector 8 is integrally fixedly connected to the curved arm 2, the protrusion 7, the connector 8, the curved arm 2 and the hatch box 1 are all made of plastic. When the hatch outer panel is opened, due to the limiting effect of the opening of the side box wall of the hatch box 1, the maximum angle at which the hatch outer panel can rotate outward is 90°. The hatch outer panel reaches the maximum rotation angle when it rotates to a state perpendicular to the side outer panel of the automobile body. In this embodiment, the state of the hatch outer panel at this time is defined as the first state, and the hatch outer panel protrudes from the automobile body. When someone or other objects pass by the car, it is very likely to collide with the hatch outer panel and cause damage to the entire hatch structure.

[0034] In order to solve the above problems, this embodiment is improved on the basis of the existing automobile gooseneck cover structure, specifically:

[0035] A second rotating shaft 9 is arranged at the end of the crank arm for connecting the connecting piece. Both ends of the second rotating shaft 9 are fixed on the ear plate, and the ear plate is fixedly connected to the end of the crank arm 2 in an integral manner.

[0036] The end of the connecting member 8 used to connect the crank arm is provided with a protrusion, which can be inserted between the two ear plates. A through hole matching the second rotating shaft 9 is provided in the protrusion. The second rotating shaft 9 passes through the through hole and is rotatably connected to the connecting member through the through hole. With this arrangement, when the crank arm 2 rotates to the point where the outer panel of the flap is in the first state and cannot continue to rotate, the outer panel of the flap can continue to rotate 90° outward around the second rotating shaft 9 with the connecting member, so that the outer panel of the flap reaches a state parallel to the outer panel of the side wall of the vehicle body. In this embodiment, the state of the outer panel of the flap at this time is defined as the second state. In the second state, the outer panel of the flap will not protrude from the vehicle body, thereby avoiding the problem of flap structure damage caused by collision with the outer panel of the flap when someone or other objects pass by the car.

[0037] Furthermore, in order to facilitate the opening of the outer panel of the mouth cover, the outer panel of the mouth cover can be rotated to the first state and then to the second state with the curved arm 2. A damping structure is provided between the second rotating shaft and the through hole surface of the protrusion of the connecting member, so that the friction force between the connecting member and the second rotating shaft 9 is greater than the friction force between the sleeve at the other end of the curved arm and the first rotating shaft 3. When a smaller force is used to open the outer panel of the mouth cover, the friction force between the connecting member and the second rotating shaft 9 cannot be overcome, so that the outer panel of the mouth cover, the curved arm 2, the connecting member 8, and the second rotating shaft 9 can be synchronously rotated without generating relative movement until the outer panel of the mouth cover is in the first state. This process is exactly the same as the process of opening the outer panel of the traditional mouth cover.

[0038] In one embodiment, the damping structure adopts a flexible sleeve, which is fixed on the outer periphery of the second rotating shaft 9. The outer annular surface of the flexible sleeve is a first serrated surface, and correspondingly, the inner hole surface of the through hole is a second serrated surface meshing with the first serrated surface. Through the meshing of the first serrated surface and the second serrated surface, the friction between the second rotating shaft and the hole surface of the through hole can be increased, so that the connecting part can rotate around the second rotating shaft only under the action of a set external force load.

[0039] In this embodiment, under the action of a set external force load, the first serrated surface of the flexible sleeve can be squeezed and deformed, thereby allowing the connecting member to rotate around the second rotation axis. After the rotation is completed, the first serrated surface returns to its original state and re-engages with the second serrated surface to maintain the posture of the outer panel of the cover.

[0040] In another embodiment, the flexible sleeve is fixed to the inner surface of the through hole, and the inner annular surface of the flexible sleeve is provided with a first serrated surface. Accordingly, the axial surface of the second rotating shaft 9 is a second serrated surface meshing with the first serrated surface.

[0041] The flexible sleeve is a rubber sleeve or a silicone sleeve, etc., and those skilled in the art can select one according to actual needs.

[0042] The mouth box 1 can be made of existing technology, and is a box-shaped structure with one end open. A water leakage hole is provided at the lower edge of the bottom box wall, and the water leakage hole is used to connect a drain pipe to facilitate the drainage of water in the mouth box. The side box wall of the mouth box 1 is also provided with a buckle structure 10, which is used to be clamped and fixed with the side outer panel of the vehicle body. The open side edge of the mouth box 1 is also provided with a circle of soft rubber ring 11, which is used to fit with the outer edge of the plate body 6 in the outer panel of the mouth cover to play a sealing role.

[0043] The above-mentioned water leakage hole, buckle structure and soft rubber ring can be arranged by using the existing technology, and the further technical details thereof will not be described in detail here.

[0044] During the design of the cover structure, the cover outer panel is lower than the body side outer panel in the closed state and higher than the body side outer panel in the open state. The traditional cover design should be installed inside the cover box, with a self-draining angle of more than 3 degrees. When self-draining cannot be achieved, a leak hole should be designed at the lowest point of the refueling or charging cover box to drain water under the wheel arch. There should be a certain space between the charging seat or oil pipe and the cover outer panel to meet the static clearance requirements. During each rotation, the cover outer panel maintains a set distance from the body side outer panel to prevent damage to the body side outer panel. The soft rubber ring on the edge of the open side of the cover box has a certain amount of interference with the body side outer panel to ensure the firmness of the cover box. When disassembling the cover outer panel of the refueling or charging cover, it is necessary to ensure that the hinge and the outer panel maintain a certain gap after moving a set distance in the disassembly direction. In the process, the refueling pipe or charging seat is installed first, and then the refueling or charging cover structure is installed, or the refueling or charging cover structure is hit first.

[0045] The charging seat presses the cover of the charging port cover sealing structure. The charging seat and the port box need to maintain a certain gap requirement. The side wall of the charging seat and the charging port box interfere with the sealing structure of the port box. The gap between the charging seat and the port box must meet the set requirements. When the refueling or charging port cover is opened to the maximum position, the refueling gun or charging gun envelope is placed in the working position. It is required that the surroundings of the refueling port cover and the hinge have no interference with the refueling gun envelope. The surroundings of the charging port box and the charging gun envelope maintain a gap. At the same time, the charging gun envelope and the body side sheet metal maintain a gap. After the refueling or charging port cover is pressed and unlocked, the outer panel of the refueling or charging port cover pops up a certain height (from the R angle of the body side outer panel to the edge of the refueling or charging port cover). When the cover is opened or closed, the port box is centered in the Z direction and horizontally close to the edge of the port box to maintain a certain distance. Considering that when the front of the vehicle is parked on a slope with the front facing forward or backward, there is no area where water can accumulate in the refueling or charging port box, and the hinge has a certain drainage angle in the X direction.

[0046] The above-mentioned design requirements may adopt the design requirements of the current mouth cover structure, and further technical details thereof will not be described in detail here.

[0047] Example 2

[0048] This embodiment discloses a working method of the automobile cover structure described in Embodiment 1:

[0049] When it is necessary to open, first one end of the crank arm 2 rotates around the first rotating shaft 3, and the cover outer plate, the connecting member 8, the second rotating shaft 9, and the flexible sleeve move synchronously with the crank arm 2 to the first state, and the cover outer plate is separated from the open end of the mouth box 1 to open the mouth box. Then, under the action of a set external force, the cover outer plate overcomes the friction between the connecting member 8 and the second rotating shaft 9 caused by the flexible sleeve and continues to rotate to be parallel to the body side outer plate, reaching the second state;

[0050] When closing is required, first, under the action of a set external force, the outer plate of the mouth cover overcomes the friction between the connecting member 8 and the second rotating shaft 9 caused by the flexible sleeve and rotates from the second state to the first state, and then the outer plate of the mouth cover, the connecting member 8, the second rotating shaft 9, and the flexible sleeve move synchronously with the curved arm 2 to the outer plate of the mouth cover to close the open end of the mouth box 1.

[0051] With the flap structure and working method of the present embodiment, when the flap structure is opened, after the flap cover plate rotates to the first state, it can continue to rotate by overcoming the friction between the second rotating shaft and the connecting member through the action of external force, so that the flap outer panel is parallel to the vehicle body side outer panel, and the flap outer panel will not protrude from the overall vehicle body, thereby preventing people or other objects from colliding with the flap structure when passing by, thereby causing damage to the flap structure. Moreover, by providing the second rotating shaft and the damping structure, the flap outer panel can be rotated to a state parallel to the vehicle body side outer panel. Compared with the traditional four-link flap structure, the structure is simpler, the difficulty and cost of the manufacturing process are reduced, and the weight and volume of the flap structure will not be increased.
