Description
[0001] DOOR HINGE WITH INTEGRATED STEPPED STOPPER
[0002] Technical Field
[0003] The invention relates to the door hinge with integrated stepped stopper, which allows the cargo doors to be opened in a controlled manner and stop at the desired angle.
[0004] In particular, the invention relates to a door hinge with integrated stepped stopper made of aluminum material to reduce carbon emission and hinge weight.
[0005] State of the art
[0006] Door hinges used in cars are mechanical parts used to connect vehicle doors to the body of the vehicle and to open and close the vehicle. These hinges are usually made of sturdy and durable materials and are subject to constant use. In addition, door hinges are exposed to vibrations, impacts and various external factors while driving. Stepped hinges are also used on vehicle doors.
[0007] In the state of art, the hinge and the control arm are positioned independently of each other in the vehicles. After the vehicle door is connected to the vehicle body, the pull handle is mounted from the lower or upper part of the hinge. However, vehicle manufacturers create different housings for hinges and different housings for control arms in order to use the hinge and the pull handle in the same place. In addition, the hinge and pull handle are screwed and connected to the door and body. The use of two different materials for two different functions leads to an increase in the number of parts used. In this way, door and body assembly times are extended and the cost increases. Thus, a large amount of time and cost is lost for manufacturers.
[0008] Vehicles cause carbon emissions by releasing greenhouse gases such as carbon dioxide (CO2) into the atmosphere as a result of the combustion of fossil fuels. These emissions contribute to global climate change by increasing greenhouse gas concentrations in the atmosphere. Today, many companies are working to lighten the weight of vehicles. Lighter vehicles generally provide better fuel economy. Light-weight vehicles consume less energy and travel longer distances with less fuel consumption. This provides an economic advantage for drivers and operators, while at the same time reducing the carbon footprint.
[0009] In the state of art, steel alloys are commonly used to provide the desired effort in stepped vehicle hinges. However, this traditional preference is based on the preference for steel alloys, as they generally have higher strength properties. In this invention, the aluminum hinge design is developed with the aim of obtaining the strength properties provided by steel alloys. The lightweight nature of aluminum satisfies the need to provide the desired effort in stepped hinges and at the same time offers the potential to reduce overall weight.
[0010] As a result of the research conducted on the subject, application No. US11434676B2 was found. The application relates to a vehicle door hinge and a manufacturing method that can reduce the weight of a vehicle and increase production efficiency. However, there is no mention of an aluminum hinge in the application, which combines the functions of hinge and control arm and has the ability to stop gradually at the desired angles.
[0011] As a result, due to the disadvantages described above and the inadequacy of the existing solutions on the subject, it has been necessary to make a development in the relevant technical field.
[0012] Object of the Invention
[0013] The invention is inspired by current situations and aims to solve the above-mentioned problems.
[0014] The main object of the invention is to provide a stepped hinge with an integrated control arm, which offers the hinge and control arm functions together.
[0015] Another object of the invention is to ensure that the cargo doors are opened in a controlled manner and stop in the desired position.
[0016] Another object of the invention is to reduce carbon emission by lightening the weight of the hinge. In order to fulfill the purposes described above, the invention is the door hinge with integrated stepped stopper, which allows the cargo doors to be opened in a controlled manner and stop at the desired angle, and which comprises a fixed body which is the part where the hinge is connected to the vehicle, a movable body which is the part where the hinge is connected to the door, a groove on the movable body, a monolithic locking sleeve mounted on the movable body via the groove to ensure that the internal mechanism remains in predetermined step positions, a form fitting on the locking sleeve to ensure coaxial operation by bearing the movable body and the locking sleeve, a groove positioned for the hinge to stop in the desired positions, a top cover and a top sealing o-ring to protect the elements inside the hinge from external factors and to prevent the oil from leaking which is inside and necessary for the operation of the system, a locking pin which moves on the inner surface of the locking sleeve to ensure the rotation ability of the hinge, at least one spring which is placed on the slotted axis pin located in the internal mechanism to ensure that the door opens and closes via applying the necessary effort by the movable body to the locking pin during the rotation and to ensure that it fits into the step by pressing the locking pin on the groove on the locking sleeve, a slotted axis pin which comprises at least one spring inside to ensure the rotation of the hinge within the movable body and which comprises the locking pin and pin holder pressed by the springs, an oil retaining ball to prevent oil leakage at the bottom and top of the slotted axis pin, a lower sliding bearing to increase the rotation ability by reducing friction force when the movable body rotates, a sliding washer to increase the rotation ability by reducing the friction force when there is a rotation movement on the contacting upper and lower surfaces of the movable body and the fixed body, a bottom cover and bottom sealing o-ring to protect the elements inside the hinge from external factors and to prevent the oil from leaking which is inside and necessary for the operation of the system, an upper sliding bearing to increase the rotation ability by reducing the friction force when the movable body rotates, a fastening pin to ensure that the system remains stable by combining the internal mechanism with the fixed body connected to the vehicle, and a pin holder to prevent noise and deformation of the locking pin, which is placed in the channel on the slotted axis pin, during the operation of the system over time.

[0048] Detailed Description of the Invention
[0049] In this detailed description, the preferred embodiments of the door hinge (18) with integrated stepped stopper of the present invention are explained only for a better understanding of the subject.
[0050] The door hinge (18) with integrated stepped stopper ensures that the cargo doors are opened in a controlled manner and stopped at the desired angle. It can be moved via the steps by applying a sufficient control force in a predetermined position in which the door must be stopped. This feature promotes safe use and is widely used in commercial vehicles, trucks and other vehicles. Cargo doors are important to facilitate load handling operations and to ensure the safety of transported materials. The stepped door stopper integration makes this functionality more user-friendly and safer.
[0051] High-strength aluminum alloy, commercial vehicle door hinge (18) with integrated stepped stopper has a simple and reliable structure, providing a significant weight reduction effect. The rear cargo door hinge system with integrated stepped door stopper is used to control the opening and closing processes of cargo doors and stop in a stepped way. The feature of the stepped door stopper allows the cargo door to stop at the desired angle. In an alternative embodiment of the invention, the hinge opens and closes at 45, 90, 180 and 270 degrees. This feature ensures a safe use for users as the door does not open completely or close suddenly. The cargo door is gradually opened to the desired angle and then held at the desired angle.
[0052] The door hinge (18) with integrated stepped stopper consists of an internal mechanism (17), a fixed body (1 ), a movable body (2), a locking sleeve (3), a top cover (4), a slotted axis pin (5), a top sealing o-ring (6), an oil retaining ball (7), a locking pin (8), a lower sliding bearing (9), a sliding washer (10), a bottom cover (11 ), an upper sliding bearing (12), a bottom sealing o-ring (13), a fastening pin (14), a spring (15) and a pin holder (16).
[0053] The fixed body (1) is the part where the hinge is attached to the vehicle. The movable body (2) is the part where the hinge is attached to the door. There is a groove (2a) on the movable body (2). The fixed body (1) and the movable body (2) are coated to prevent contact corrosion. The locking sleeve (3) is mounted to the movable body (2) by means of the groove (2a), ensuring that the internal mechanism (17) remains in the predetermined step positions (angles). In an alternative embodiment of the invention, the locking sleeve (3) is made of steel material to provide the effort in the steps. The locking sleeve (3) is monolithic, and there is a form fitting (3a) and a groove (3b) thereon. The form fitting (3a) allows the movable body (2) and the locking sleeve (3) to work coaxially by bearing. In an alternative embodiment of the invention, the form fitting (3a) and / or the serrated structure are used together. The top cover (4) and the top sealing o-ring (6) protect the elements inside the hinge from external factors and prevent the oil from leaking which is inside and necessary for the operation of the system. The slotted axis pin (5) comprises a locking pin (8) and a pin holder (16), which comprises at least one spring (15) and where the springs (15) press, in order to provide the rotational movement of the hinge in the movable body (2). The slotted axis pin (5) has an oil retaining ball (7) at the top and bottom to prevent oil leakage. The locking pin (8) moves on the inner surface of the locking sleeve (3), ensuring the rotational ability of the hinge. There is a locking pin (8) and a groove (3b) positioned to keep the hinge in the desired positions. The locking pin (8) is placed on these grooves (3b) and stopping in the desired position is achieved. The lower sliding bearing (9) increases the rotational ability by reducing the friction force when the movable body (2) makes a rotational movement. The sliding washer (10) increases the rotational ability by reducing the friction force when there is rotational movement on the contacting upper and lower surfaces of the movable body (2) and the fixed body (1). The bottom cover (11 ) and the bottom sealing o-ring (13) protect the elements inside the hinge from external factors and prevent the oil from leaking which is inside and necessary for the operation of the system. The upper sliding bearing (12) increases the rotational ability by reducing the friction force when the movable body (2) makes a rotational movement. The fastening pin (14) ensures that the system remains stable by connecting the internal mechanism (17) with the fixed body (1) connected to the vehicle. It allows the movable body (2) to rotate, which is connected to the door. At least one spring (15) is supported on the slotted axis pin (5) in the internal mechanism (17) and ensures that the door is opened and closed via applying the necessary effort by the movable body (2) to the locking pin (8) during the rotation. The spring (15) presses the locking pin (8) on the groove (3b) on the locking sleeve (3) to ensure that it fits into the step. The pin holder (16) is made of polymer material to prevent noise and deformation of the locking pin (8), which is placed in the channel (5a) on the slotted axis pin (5), during the operation of the system over time.
