Description

Technical Field

[0001] This utility model relates to the technical field of vehicle door hinge structure, specifically to a driver's cab door hinge structure. Background Technology

[0002] A hinge, also known as a door hinge, is a structural device used to connect two solid objects and allow relative rotation between them. When connecting a car door to the car body, a hinge is usually required. Types of door hinges generally include wing-type door hinges, scissor door hinges, sliding door hinges, revolving door hinges, and hinges for both the old and new Volkswagen Sagitar models.

[0003] The current cab door hinge structure, due to the weight of the door and the long-term rotation and hinge operation, will wear down during use. Especially in some vehicles that enter and exit dusty environments, dust will accumulate at the hinge connection points, causing abnormal noises from the hinges every time the door is opened and closed, affecting the user experience.

[0004] To address this, a new cab door hinge structure is proposed, which upgrades and modifies the existing device to resolve these shortcomings. Utility Model Content

[0005] The purpose of this utility model is to provide a cab door hinge structure in order to solve the problems in the background technology.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A driver's cab door hinge structure includes a door body, a fixed block, a rotating block, and a vehicle body. The fixed block is disposed on one side of the door body. A bolt is provided at the end of the fixed block away from the door body, and one end of the bolt passes through the fixed block and is threadedly connected to the inner wall of the door body. The inner side of the fixed block is rotatably connected to the outer end of the rotating block. The end of the rotating block away from the fixed block is disposed on the outer side of the vehicle body. A bolt is provided on the inner side of the rotating block, and one end of the bolt passes through the rotating block and is threadedly connected to the inner wall of the vehicle body. A pin is provided at the upper end of the door body, and one end of the pin passes through the fixed block and the rotating block. A lubrication mechanism is provided on the inner side of the rotating block.

[0008] Furthermore, a connector rod is inserted into the lower side of the outer end of the pin shaft.

[0009] Furthermore, a limit block is fixedly connected to one end of the fixed block, and stop blocks are fixedly connected to the upper and lower sides of the rotating block, with the outer end of the stop block abutting against the outer end of the limit block.

[0010] Furthermore, the lubrication mechanism includes a liquid storage tank. The outer end of the liquid storage tank is fixedly installed on the inner side of the rotating block. An inlet is fixedly connected to the outer end of the liquid storage tank. A three-way pipe is fixedly installed on the lower outer side of the liquid storage tank near the inlet. One end of the three-way pipe near the pin shaft is fixedly installed on the upper surface of the rotating block, and the other end of the three-way pipe near the pin shaft is fixedly installed on the bottom inner side of the rotating block. A cavity is opened on the upper side of the interior of the liquid storage tank. An elastic air block is fixedly installed on the inner wall of the cavity. The air outlet of the elastic air block is connected to the upper inner wall of the liquid storage tank. A compression block is fixedly installed on one end of the elastic air block. A slider at the end of the compression block away from the elastic air block passes through the liquid storage tank and abuts against a compression plate. The two sides of the compression plate near the liquid storage tank are fixedly connected to the outer ends of the limiting block.

[0011] Furthermore, a one-way port is fixedly installed on the inner wall of the liquid inlet.

[0012] Furthermore, a sealing plug is provided on the upper side of the one-way port, the lower end of the sealing plug is sleeved with the inner wall of the liquid inlet, and a pull ring is fixedly connected to the upper end of the sealing plug.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention allows the fixed block to rotate on the rotating block when the main body of the car door is opened, enabling the limiting block to contact the stop block. This facilitates the squeezing plate to squeeze the squeezing block, and the elastic inflatable block to inflate the liquid storage tank. This increases the air pressure inside the liquid storage tank, allowing the lubricating oil inside the tank to flow through the three-way pipe to the connection between the fixed block and the rotating block, thus lubricating the connection. This not only improves the service life of the connection between the fixed block and the rotating block but also reduces any abnormal noises that may occur during rotation between the fixed block and the rotating block.

[0023] like Figures 1 to 3As shown, a driver's cab door hinge structure includes a door body 1, a fixing block 11, a rotating block 17, and a vehicle body 19. The fixing block 11 is disposed on one side of the door body 1. A bolt 12 is disposed at the end of the fixing block 11 away from the door body 1. One end of the bolt 12 passes through the fixing block 11 and is threadedly connected to the inner wall of the door body 1. The inner side of the fixing block 11 is rotatably connected to the outer end of the rotating block 17. The end of the rotating block 17 away from the fixing block 11 is disposed on the outer side of the vehicle body 19. A bolt 18 is provided on the inner side of the door body 1. One end of the bolt 18 passes through the rotating block 17 and is threaded to the inner wall of the body body 19. A pin 13 is provided at the upper end of the door body 1. One end of the pin 13 passes through the fixing block 11 and the rotating block 17. A lubrication mechanism 2 is provided on the inner side of the rotating block 17. Specifically, the fixing block 11 and the rotating block 17 are connected by the pin 13, so that the fixing block 11 can rotate on the rotating block 17, which facilitates the rotation between the door body 1 and the body body 19.

[0024] like Figure 1 and Figure 2 As shown, a connecting rod 10 is inserted into the lower side of the outer end of the pin shaft 13; specifically, this prevents the pin shaft 13 from disengaging from the fixed block 11 and the rotating block 17, while facilitating the quick connection of the fixed block 11 and the rotating block 17 together.

[0025] like Figure 1 and Figure 2 As shown, a limiting block 15 is fixedly connected to one end of the fixed block 11, and a stop block 16 is fixedly connected to the upper and lower sides of the rotating block 17. The outer end of the stop block 16 abuts against the outer end of the limiting block 15. Specifically, the rotation angle between the fixed block 11 and the rotating block 17 is limited by the cooperation of the limiting block 15 and the stop block 16.

[0026] like Figure 1 and Figure 3As shown, the lubrication mechanism 2 includes a liquid storage tank 27. The outer end of the liquid storage tank 27 is fixedly installed inside the rotating block 17. An inlet 22 is fixedly connected to the outer end of the liquid storage tank 27. A three-way pipe 23 is fixedly installed on the lower outer end of the liquid storage tank 27 near the inlet 22. One end of the three-way pipe 23 near the pin shaft 13 is fixedly installed to the upper surface of the rotating block 17, and the other end of the three-way pipe 23 near the pin shaft 13 is fixedly installed to the bottom inner side of the rotating block 17. A cavity 28 is opened on the upper side of the interior of the liquid storage tank 27. An elastic air block 29 is fixedly installed on the inner wall of the cavity 28. The air outlet of the elastic air block 29 is connected to the upper side of the inner wall of the liquid storage tank 27. A compression block 290 is fixedly installed on one end of the elastic air block 29. The end of the compression block 290 away from the elastic inflatable block 29 passes through the liquid storage tank 27 and abuts against the compression plate 14. The two sides of the end of the compression plate 14 near the liquid storage tank 27 are fixedly connected to the outer end of the limiting block 15. Specifically, the limiting block 15 can contact the stop block 16, so that the compression plate 14 can compress the compression block 290, so that the elastic inflatable block 29 can inflate the liquid storage tank 27, thereby increasing the air pressure inside the liquid storage tank 27. The lubricating oil inside the liquid storage tank 27 can flow through the three-way pipe 23 to the connection between the fixed block 11 and the rotating block 17 to lubricate the connection between the fixed block 11 and the rotating block 17, which not only improves the service life of the connection between the fixed block 11 and the rotating block 17.

[0027] like Figure 1 and Figure 3 As shown, a one-way port 26 is fixedly installed on the inner wall of the liquid inlet 22. A sealing plug 21 is provided on the upper side of the one-way port 26. The lower end of the sealing plug 21 is sleeved with the inner wall of the liquid inlet 22, and a pull ring 25 is fixedly connected to the upper end of the sealing plug 21. Specifically, this is to facilitate blocking the liquid inlet 22 and prevent air from being discharged from the liquid inlet 22.

[0028] In summary: By opening the main body 1 of the car door, the fixed block 11 rotates on the rotating block 17, allowing the limiting block 15 to contact the stop block 16, thus limiting the rotation between the fixed block 11 and the rotating block 17. This facilitates the squeezing plate 14 to squeeze the squeezing block 290, causing the elastic inflation block 29 to inflate the inside of the liquid reservoir 27, increasing the air pressure inside the liquid reservoir 27. This allows the lubricating oil inside the liquid reservoir 27 to flow through the three-way pipe 23 to the connection between the fixed block 11 and the rotating block 17, lubricating the connection and ensuring that the fixed block 11 and the rotating block 17 will not experience any obstruction during long-term use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
