Description

1 TARIFF A COVER SYSTEM FOR VEHICLES Subject of the Invention 5 The invention involves fuel tank caps or electrical outlets in vehicles. when opening the charging tank caps in vehicles by balancing the rotational movement that occurs, the lid is controlled and easy opening and therefore sudden opening preventing accidents and deformations and reducing costs by 10 a tank cap system developed for the purpose of reducing It is related. State of the Art Today, motor vehicles have manually operated gasoline / electrical systems. Various mechanisms are used in the lids of fuel tanks. (The following is a list of references / instruments) The mechanisms used generally involve a cocking spring or a dead point cocking spring. It has a spring. In mechanisms with a winding spring, the lid opens suddenly, and this 20 the situation may result in injuries or damage to the cover from hitting the surroundings This is the reason. In single-winding spring mechanisms, it is very fast and stiff. rebound effects at the end point due to opening It is being observed. The broadcast is continuously established. Because of this, the plastic, which is subjected to the maximum moment, changes over time to 25. deformations such as gaps and flushes occur. in addition to reducing its lifespan, it also negatively affects its appearance. It has an effect. Especially with lids that open diagonally upwards, lid opening As the degree increases, the center of gravity of the cover and carrier part becomes z 30 Since the potential energy increases as it is shifted upwards (+) on the axis 2 The moment required to hold the lid open is increasing (Figure-1). Setup The spring loses its strength as it is unwound from its coiled position (Figure- 2). In other words, the increase in the moment of gravity and the tension spring. inability to fully open (freeplay) due to loss of power, etc. Situations like this can be encountered. The problem of not being able to open completely is one of 5. Another reason is that the springs' strength decreases with prolonged use. It demonstrates that instead of spring-loaded winding mechanisms, dead-point winding is used. In mechanisms involving springs, the spring provides a closing force of up to 45°. Because of the procedure, the user needs to tilt the tank lid up to 45° to open it. He needs to open the lid (Figure-3). This situation affects usability 10. This creates a disadvantage in that respect. In engineering, opening and closing mechanisms are used in gasoline / electric fuel tank caps. to eliminate the disadvantages in their mechanisms There are developments. In technology, 15 is used to slow down the opening of the cocking spring. There are mechanisms with added dampers that have been developed. (The following is a list of topics / instruments) The mechanisms involved are usually in side-opening fuel tank caps. These mechanisms are used. Examples of such mechanisms include: Fuel as described in utility model document number CN205172262U A damped opening with a damping function for the filling hole cover 20 The mechanism can be given. The mechanism described in utility model document CN205172262U is a fuel tank cap base and a fuel tank cap top It includes the cap, the top cap in question is the fuel filler cap. It is placed in an opening in the base. The cover base head 25 part of it extends outwards with the hinge housing, and the hinge housing A damper is attached to one side. This damper is a damper. It is equipped with a gear and is located on top of the fuel tank cap. The lid's top extends outwards via an articulated arm. A pin is fixed to one end of the hinge arm, and the pin is attached to the hinge 30 mounted in its housing in a rotatable manner, connected to each other by a damper gear. 3 fitted with a passing pin gear and hinge housing, a mounting It is equipped with a spring. The damper located in the aforementioned mechanism. The established broadcasting company is not reducing the force it initially exerted. Therefore, the force of the spring when opening is exponential. a controlled and gentle opening due to the decrease 5 It cannot be implemented; the deformation problem persists. In addition, the addition of a damper is involved in this mechanism. by creating an additional cost, both for the producer and indirectly reduces maintenance and renewal costs for the end user. It increases. 10 Another example of the state of the art is CN208698496U. A number of utility model documents can be provided. The aforementioned documents This relates to the spring mechanism of fuel tank caps in vehicles. The spring mechanism of the fuel tank cap discussed in the document differs from others. It also includes a cover and a cover spring. The spring in question is 15 It consists of a metal elastic part and an elastic arm, and in this structure When the lid is about to be opened, the jammed spring releases and the latch... compressing and rotating the elastic arm around the axis of rotation, Thus, it opens the cover. The operation of the system described in the document is simple. This is achieved with a spring mechanism, providing rebound effects and 20 Deformation problems may occur. Another example of the state of the art is CN107089134A. A number of patent documents may be issued. The structure in question is the subject of the aforementioned document. a hinge that connects the fuel tank cap to the vehicle body It has a rotating handle connected to a shaft, and the rotation is 25°. a spring to provide elastic force to drive the arm It is assembled. Depending on the opening mechanism for the tank lid, it rotates. The spring is designed to rotate the arm, along with the cover, to its maximum point. It is driven by the elastic force it provides and automatically It does not close and the turning arm does not respond to any force in the extension direction. It is not exposed to. The document creation mechanism is based on a spring-loaded structure, 4 in terms of structural deformation and rebound effects It is thought that this will create a disadvantage. To overcome the disadvantages mentioned above, fuel fuel tank caps or charging tanks in electric vehicles by balancing the spring forces during the lid opening process 5 It provides a smooth opening, and a rebound effect when opened. eliminating the deformation of the lid and mechanism A low-cost, barrier-resistant cover system has been developed. Detailed Description of the Invention The invention relates to fuel tank caps on vehicles or in electric vehicles. a cover system developed for charging port covers It is related. One purpose of the invention is to facilitate the opening of fuel tank or charging tank caps. In this process, the spring forces are balanced to create a smooth, controlled 15 It is the development of a system that enables opening (Figure-13). One purpose of the invention is to prevent accidents caused by the sudden opening of the lid. prevention. One purpose of the invention is to counteract the rebound effect caused by sudden opening. The goal is to prevent these effects. 20 One purpose of the invention is to continuously apply pressure to the spring while the cover is closed. Preventing deformations by reducing the maximum force and Therefore, the aim is to increase the lifespan of the parts. One purpose of the invention is to improve the performance of lids, especially those that open diagonally upwards. the opening problem caused by the increase in the gravitational moment occurring 25 It is the elimination of. Another aim of the invention is to create a low-cost tank lid system. It is the production of. The invention relates to a fuel tank for vehicles that is attached to the vehicle body. or one that includes at least one cover (3) located in the charging port inlet It is a cover system, in its most general form; a cover (3) that carries carrier (2), connected with the aforementioned carrier (2), cover (3) a spring (5) that continuously pushes the lid (3) 5 depending on the degree of opening, either in the opening direction or the closing direction. a dead point cocking spring (6) that applies a pushing force, cocking passing through the spring (5), the winding spring (5) and dead point winding containing at least one pin (4) that provides the connection between the spring (6) a drive mechanism (9) and the aforementioned drive mechanism (9) 10 a body (1) and lid (3) to which it is attached and kept closed It includes at least one locking mechanism (8) that provides. In one configuration of the invention, the pin (4) is the dead point setting spring. (6) at least one opening for at least one end to pass through It includes. In one configuration of the invention, the pin (4) is 15 of the cover (3). It is perpendicular to the axis of rotation. A configuration of the invention is the moment from the winding spring (1) It contains at least one buffer (7) for stabilization. A configuration of the invention allows the lid to close up to (3) 45°. The correct pushing force, the pushing force in the opening direction after 45° is 20. It includes a dead point spring (6) that applies. The invention relates to fuel tanks or charging docks in electric vehicles. balancing the spring forces during the lid opening process It is softer than the systems used in the technology, and it vibrates when opened. 25 that eliminates the rebound effect and undergoes less deformation. and to provide less costly locking mechanisms locking mechanisms that use two different types of springs It is related to this. Especially in tank covers that open diagonally upwards. Eliminating opening problems caused by increased moment of gravity This is ensured. 30 6 Among the most important advantages of the invention is the double spring (coiling spring (5)+ The invention includes a dead point spring (6). the double spring actuation mechanism in the system, the cocking spring (5) long term environment due to reduction of initial force Its effect on reducing gap and flush changes under these conditions is 5. It is located there. By increasing the force when the lid is fully open... The continuous opening of the part is supported. The system that is the subject of the invention. It is being stripped of the perception also known as incomplete freedom play, Achieve a smooth opening, almost like automatic opening. is being done. 10 The system relating to the configuration of the invention is shown in Figure 4. is shown. A body (1) is shown in more detail in Figure 4. carrier (2), cover (3), pin (4), cocking spring (5), dead point cocking The spring (6), buffer (7) and lock (8) are shown. The subject of the invention The most important features that distinguish the system from the known state of the art are 15 There are two different springs between the winding spring (5) and the dead point winding. publication (6) includes together. In the system described in the invention, the driving force is transmitted by two springs. is provided. The spring (5) continuously opens the lid (3). It applies a force in the direction of the dead point spring (6) 45° to 20°. Closing up to 45° helps to open after that. Lid (3) To reduce the opening moment that occurs when the lid (3) is open In this state, it attempts to increase the opening moment. Another In other words, the pushing force that the spring (5) continuously applies is dead Damped up to 45° by the dotted spring (6), after 45° 25 This is also supported. This situation prevents accidents caused by sudden opening. to prevent the moment of gravity from increasing as the lid (3) is opened Therefore, to prevent the failure of the spring (5) to force. to ensure the plastic deformation time of plastic parts. This extends the lifespan of the system's stable operation. 30 7 gaps and flushes caused by plastic deformation This prevents their deterioration. The key (8) in the system which is the subject of a configuration of the invention, It is used to keep the lid (3) closed. Tampon (7) part while the lid is closed, 5 comes from the winding spring (5) (from the 1st spring). It serves the function of balancing the moment. The drive system involved in the invention is a configuration of the system. in the mechanism (9), where the pin (4) carrier and springs are placed and the drive mechanism fixed adjacent to the body (1) (9) is located and is positioned perpendicular to the axis of rotation. 10 and dead point spring (6) at one end and spring at the other end It carries the broadcast. In the system which is the subject of a configuration of the invention, the cover (3) is cross and opening upwards and together with the carrier (2) as weight It weighs approximately 425 grams. Potentially 15 when the lid (3) is opened. The energy difference is increasing. In the side-opening hatches (3) mentioned No potential difference is encountered. Coil spring (5) cover (3) It loses strength as it opens. At this point, it's a dead-point setup. The spring (6) comes into play as a supporting force. With the lid (3) in the closed position, the opening spring (5) must be continuously opened 20 It applies force. In technology, it only contains a coil spring. due to the force mentioned in the mechanisms, in plastics Deformation occurs. The dead cells in the system that is the subject of the invention. The dotted spring (6) reduces the opening force, while the buffer (7) Preventing warping of parts by applying a load opposite to the moment 25 It is helpful. As the opening angle increases in gasoline tanks that open upwards diagonally The force exerted by the weight against the opening is increasing. To fully open the lid (3) when using the spring alone Approximately twice the initial moment is required (~1300 Nmm³). 30 8 The double spring drive mechanism included in the system described in the invention. Thanks to this, the aforementioned moment has been reduced to ~700Nmm, eliminating the dead point. By further reducing the initial force with the spring (6) (2nd spring) (~480Nmm) long-term warping / deformation effect on the part. It has been reduced. The moment applied by a single spring at full opening is 5. When the values ​​drop to ~350Nmm, the dead point winding spring (6) extra with a moment (~180Nmm) sufficient moment for full opening (>450Nmm) This is provided by the double spring system included in the invention. Thanks to the mechanism, it opens quickly and forcefully and rebounds at the final point. Preventing (jittering) effects or problems with not opening completely 10 This is being done to prevent the deformation problem. passing through and dead point setup (6) contributes to full opening Therefore, this problem is eliminated.
