Description

Technical Field

[0001] The utility model relates to the technical field of vehicle door hinge equipment, in particular to a high-strength vehicle door hinge. Background Art

[0002] Auto parts are the various units that make up a car and the products that serve the car. There are many different types of auto parts. As people's living standards improve, they are spending more and more on cars, and the auto parts market is growing. Among auto parts, car door hinges are crucial components that ensure the opening and closing of car doors. Because car doors themselves require a high safety factor, and they are often subjected to strong impacts during use, the door hinge plate itself must have high strength and stability. When installing existing car hinges, they often need to be constantly adjusted to the appropriate installation position according to the installation situation, which is time-consuming and labor-intensive. Furthermore, when lubricating existing hinges, the lubricant does not penetrate well into the internal connection of the hinge.

[0003] Application number CN202321923337.0 discloses a high-strength door hinge, which relates to the field of automotive accessories technology. It includes a main connecting block and a secondary connecting block rotatably connected to the upper surface of the main connecting block. Special gaskets are provided on one side of the outer surface of each of the main connecting block and the secondary connecting block. Positioning blocks are fixedly connected to one side of the outer surface of each of the main connecting block and the secondary connecting block. The outer surface of the main connecting block is provided with a vehicle body, and a positioning groove is provided on one side of the outer surface of the vehicle body. Compared with existing ordinary high-strength door hinges, this high-strength door hinge, when installed, places the positioning block in the positioning groove that has been pre-stamped on the vehicle body and door. Tightening the bolts can keep the door and the body in the correct installation position, eliminating the need to repeatedly loosen and tighten the bolts to adjust the relative position of the door and the body according to the installation situation. The special gasket can strengthen the fixing strength of the bolts. This design can improve installation quality and assembly efficiency.

[0004] The high-strength door hinge disclosed in the above document has the following defects: during use, the door hinge operates by pulling one hinged component to drive another component. When opening and closing the door daily, the hinged component needs to be pulled frequently. In the end, the connection between the two hinged components may not be stable enough, which may cause damage to the component. It is necessary to set a corresponding structure to make the door hinge more stable.

[0005] It can be seen from this that the existing high-strength door hinge does not have the function of improving the stability of the hinge block connection. It is necessary to improve the existing deficiencies and provide a function that can improve the stability of the hinge block connection. Utility Model Content

[0006] The purpose of the present invention is to provide a high-strength vehicle door hinge to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0008] The utility model is a high-strength vehicle door hinge, comprising a component one and a component two, wherein the component two is hinged on the inner wall of the component one, and the component one comprises a connecting block, wherein a groove is provided on the middle outer wall of the connecting block, and positioning grooves are provided on the inner walls on both sides of the middle of the groove, and a cylindrical block is rotatably connected to the inner wall of the positioning groove, and a reinforcing block is provided on the outside of the cylindrical block, and the middle parts of the reinforcing block and the cylindrical block are located in the groove of the connecting block. The purpose of such arrangement is that during the use of the door hinge, the base and the mounting block are respectively mounted inside the vehicle and on the vehicle door, so that the vehicle door is fixed at the door frame for opening and closing movements. When the vehicle door begins to close, the mounting block is driven forward and backward by the vehicle door. When the mounting block extends forward, the rotating block and the limiting block respectively pull the long rod and the reinforcing block forward together. The long rod moving forward drives the connecting block connected to the front end, and the top end of the connecting block is pulled forward. At this time, the reinforcing block and the connecting block move forward together. When the reinforcing block moves, it drives the middle cylindrical block and the middle end of the connecting block connected to it to move forward together. The reinforcing block and the cylindrical block are accommodated and limited by the groove. The positioning groove limits the cylindrical block and the middle end of the reinforcement block to perform circular motion, and the top and middle end of the connecting block are driven forward together, and the tail end of the connecting block is hinged to the base through the positioning rod, so that the connecting block can cooperate with the long rod to perform stretching motion on the base and the mounting block. The top end of the reinforcement block is hinged to the hinge block 1, and the reinforcement block stretches the top hinge block 1 of the support rod forward when moving forward. The hinge block 1 at the tail end of the support rod is hinged to the base, so that the reinforcement block can cooperate with the support rod to assist in reinforcing the tensile motion of the connecting block and the long rod on the base and the mounting block. The structure sets two hinge blocks to be closely connected and move in coordination, thereby improving the stability of the door hinge.

[0009] Furthermore, the first component includes a base, with positioning rods rotatably connected to the inner walls of one end of the base. The rear end of the connecting block is sleeved onto the outside of the positioning rods. This arrangement is intended to allow the rear end of the connecting block to be hinged to the base via the positioning rods during use of the door hinge, allowing the connecting block to cooperate with the long rod to stretch the base and the mounting block.

[0010] Furthermore, a support rod is provided on the other side of the base, and hinge blocks 1 are provided at each end of the support rod. The hinge blocks 1 at the bottom are hinged to the inner walls on both sides of the other end of the base. This arrangement is intended to ensure that when the door hinge is in use, the top end of the reinforcement block is hinged to the hinge block 1, and when the reinforcement block moves forward, it pulls the hinge block 1 at the top of the support rod forward.

[0011] Furthermore, the top end of the reinforcement block is hingedly connected to hinge block 1 at the top of the support rod. Hinge blocks 2 are rotatably connected to the inner walls on both sides of the top end of the connecting block, and a long rod is provided at the bottom end of the second hinge block. This arrangement is intended to ensure that when the door hinge is in use, the long rod drives the connecting block forward through hinge block 2, pulling the top and middle ends of the connecting block forward together. The rear end of the connecting block is hinged to the base via a positioning rod, allowing the connecting block to cooperate with the long rod to stretch the base and the mounting block.

[0012] Furthermore, the bottom end of the reinforcement block is hingedly connected to a rotating block, and a limit block is hingedly connected to the outer wall of the bottom end of the rotating block. The limit block is hingedly connected to the bottom end of the long rod. This arrangement is designed so that when the door hinge is in use, when the mounting block extends forward, the long rod and the reinforcing block are pulled forward together by the rotating block and the limit block respectively. The forward movement of the long rod drives the connecting block connected to the front end.

[0013] Furthermore, the rotating block is located inside the stop block, and a mounting block is provided at the end of the rotating block adjacent to the stop block. This arrangement allows the mounting block to be driven forward and backward by the vehicle door during use of the door hinge. When the mounting block extends forward, the rotating block and the stop block pull the long rod and the reinforcing block forward, respectively. The long rod then pulls the connecting block forward, and the reinforcing block then pulls the support rod forward.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model sets a reinforcing block and a support rod. The top end of the reinforcing block is hinged to the hinge block 1. When the reinforcing block moves forward, the top hinge block 1 of the support rod is stretched forward. The hinge block 1 at the rear end of the support rod is hinged to the base. The reinforcing block can cooperate with the support rod to assist in the stretching movement of the reinforcement connection block and the long rod on the base and the mounting block. The two hinge blocks of this structure are tightly connected and move in coordination, thereby improving the stability of the door hinge.
