Description

Technical Field

[0001] This utility model belongs to the field of automotive hinges, specifically relating to a bidirectional adjustable hinge. Background Technology

[0002] With the improvement of living standards, the domestic demand for high-end MPV models continues to grow. Most domestic OEMs are developing high-end MPV models. The refinement of the overall vehicle appearance and the precision of door gaps and surface defects need to be improved. Reducing door gaps and surface defects is the minimum requirement for high-end MPVs. Since MPVs are sliding door models, there is no fixed way to install sliding doors. The gaps and surface defects of sliding doors need to provide a multi-directional adjustment strategy from the sliding door hinges. When producing MPV models, the gaps and surface defects of the whole vehicle can be adjusted, reducing the rework rate, thereby improving production efficiency and reducing production costs.

[0003] Traditional locating pin sliding door hinges can only be designed with adjustment in one direction. Designing a locating pin hinge with two adjustment directions will cause the hinge to be installed off-center, resulting in abnormal noise from the rollers.

[0004] Currently, Mercedes-Benz has designed a two-way adjustable hinge, such as Figure 1 As shown, the door mounting bracket design incorporates X-axis adjustment (lateral adjustment), with bolts and lock nuts added to the rotating shaft, and a Z-axis adjustment (longitudinal adjustment). This is the most widely used two-way adjustable hinge on the market. However, this design has the following drawbacks: 1. The addition of threads to the rotating shaft 26 for the Z-axis adjustment is inconvenient. When tightening the lock nut, the wrench 25 requires custom-made tools due to space constraints, and is not easy to operate, demanding high-performance rotating shafts. 2. The rotating shaft requires special customization, and the threaded area needs localized heat treatment to ensure thread strength while maintaining material hardness in other areas to guarantee successful riveting. 3. The hinge bearing bracket also requires a threaded structure, making it difficult to control the concentricity of the bearing bracket rotating shaft mating holes, resulting in high costs. 4. The distance between the door bracket rotating shaft and the mounting surface must be less than 50mm, making it difficult to loosen the lock nut. This dimension affects the arrangement of surrounding parts, thus limiting its functionality. Utility Model Content

Movable groove; Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0032] See Figures 3 to 10 A bidirectional adjustable hinge, shown for connection to door panel 1, includes:

[0033] A hinge body 2, the hinge body 2 includes a mounting bracket 3 and a guide wheel frame 4, the mounting bracket 3 includes a bracket body, an upper bracket plate 5 and a lower bracket plate 6 are connected to the bracket body, and the guide wheel frame 4 is hinged to the mounting bracket 3;

[0034] An adjusting plate 7 is provided, and the hinge body 2 is connected to the adjusting plate 7 by a fastening structure. The hinge body 2 is provided with a first adjusting structure, and the adjusting plate 7 is provided with a second adjusting structure.

[0035] When this utility model is used, it is shipped to the OEM as a whole. During assembly at the OEM, the fastening structure, the first adjustment structure, and the second adjustment structure need to be loosened first. The process of installing it on the car door is as follows: First, the hinge body 2 and the adjustment plate 7 are initially positioned and connected to the door panel 1. Then, the position of the adjustment plate 7 or the hinge body 2 is adjusted by the first adjustment structure and the second adjustment structure to match different car models. The first adjustment structure is a longitudinal or lateral adjustment structure, and the second adjustment structure is a longitudinal or lateral adjustment structure perpendicular to the direction of the first adjustment structure. After the hinge body 2 is adjusted to the correct position, the fastening structure is used to fasten the hinge body 2 and the adjustment plate 7 to the door panel 1.

[0036] Furthermore, such as Figures 3-5The first adjustment structure is a longitudinal adjustment structure, the second adjustment structure is a transverse adjustment structure, and the fastening structure includes an enlarged hole 8 opened on the upper support plate 5 and the lower support plate 6, and an adjustment groove 9 (horizontally set) opened on the adjustment plate 7. The adjustment groove 9 and the enlarged hole 8 are matched. Specifically, the first adjustment structure of this utility model is a longitudinal adjustment structure, used to adjust the specific position of the hinge body 2 in the longitudinal direction. The second adjustment structure is a transverse adjustment structure, used to adjust the specific position of the adjustment plate 7 and the hinge as a whole in the transverse direction. The fastening structure consists of enlarged holes 8 respectively provided on the upper support plate 5 and the lower support plate 6, and an adjustment groove 9 on the adjustment plate 7. This allows the screw 16 to pass through the enlarged holes 8 and the adjustment groove 9 and be fastened to the door panel 1. When the screw 16 is fastened, the hinge body 2 and the adjustment plate 7 can be pressed together. The reason for using the enlarged holes 8 is to allow the screw 16 to have a certain amount of room to move in the enlarged holes 8 before being pressed together, so that the hinge body 2 will not be interfered with when moving longitudinally, and the adjustment plate 7 and the hinge body 2 as a whole will not be interfered with when moving laterally.

[0037] Furthermore, the longitudinal adjustment structure includes two longitudinal slots 10 formed on the upper support plate 5 and the lower support plate 6. A locking bolt 11 for connecting with the adjustment plate 7 passes through one longitudinal slot 10. The adjustment plate 7 has a sliding limiting member 12 that matches the other longitudinal slot 10. In this invention, adjustment is first performed in the longitudinal direction of the hinge body 2, specifically through the longitudinal adjustment structure. After the longitudinal position adjustment is completed, the locking bolt 11 is tightened, and the adjustment plate 7 and the hinge body 2 are integrated as a whole, allowing for lateral adjustment of the adjustment plate 7. When the adjustment plate 7 moves laterally, the hinge body 2, as a whole with the adjustment plate 7, also moves laterally. Compared to traditional bidirectional adjustment structures, this invention is smaller, more flexible and convenient to adjust, and has lower production costs. Additionally, graduations can be provided on both sides of the longitudinal slots 10 for accurate measurement during adjustment. The sliding limiting member on the adjustment plate 7 is a stamped protrusion and does not require separate connection.

[0038] Furthermore, the lateral adjustment structure includes a lateral groove 13 formed in the middle of the adjustment plate 7. A positioning screw 14 passing through the lateral groove 13 is connected to the adjustment plate 7, and a locking nut 15 is threaded onto the positioning screw 14. The lateral adjustment structure includes the lateral groove 13 in the middle of the adjustment plate 7. When lateral movement of the hinge body 2 is required, the hinge body 2 and the adjustment plate 7 act as a single unit. In this case, only the position of the adjustment plate 7 needs to be adjusted. Specifically, the locking nut 15 is loosened, the position of the adjustment plate 7 is moved, and finally the locking nut 15 is tightened onto the positioning screw 14 (the positioning screw 14 has a positioning head at its tail). Additionally, graduations can be provided on both sides of the lateral groove 13 for accurate measurement during adjustment.

[0039] Furthermore, the lateral adjustment structure also includes a sliding limiter 12 on the adjustment plate 7, and a sliding groove 17 matching the sliding limiter 12 is provided on the door panel 1. Figures 3 to 5 Based on the previous embodiment, the sliding pin and sliding groove 17 are provided, which ensures that the adjusting plate 7 moves only in the horizontal direction when moving laterally, and will not deviate or rotate around the positioning screw 14, making the adjustment of the lateral position more precise. This sliding limit component is also a protrusion formed by stamping, and does not require separate connection.

[0040] Furthermore, such as Figure 6 As shown, the lateral adjustment structure also includes a secondary lateral groove 18 on the adjustment plate 7. A secondary positioning screw 19 passing through the secondary lateral groove 18 is connected to the adjustment plate 7, and a secondary locking nut 20 is threaded onto the secondary positioning screw 19. Specifically, the secondary lateral groove 18 can replace the matching of the sliding limit member and the sliding groove 17. Specifically, a secondary positioning screw 19 is connected to the door panel 1, and a secondary locking nut 20 is also fixed on the secondary positioning screw 19. When adjusting the position of the adjustment plate 7, the adjustment plate 7 will only move in the horizontal direction and will not deviate.

[0041] Furthermore, a flanged nut plate 21 is fixed to the back of the door panel 1. The flanged nut plate 21 is provided with a welding nut 22 that matches the enlarged hole 8. The flanged nut plate 21 is provided with a first through hole and a second through hole. Specifically, in order to further improve the firmness of the bidirectional adjustable hinge connected to the door panel 1, a flanged nut plate 21 is also fixed to the back of the door panel 1 to facilitate a more secure fastening between the screw 16 and the door panel 1. Correspondingly, the flanged nut plate 21 is provided with a first through hole 23 that matches the positioning screw 14, and a second through hole 24 that matches the sliding limit member or the secondary positioning screw, to facilitate the connection of the positioning screw 14, the secondary positioning screw 19, or the sliding limit member 12.

[0042] Furthermore, such as Figures 8-9 As shown, the longitudinal adjustment mechanism includes two longitudinal slots 10 respectively opened on the upper support plate 5 and the lower support plate 6. The lateral adjustment mechanism includes a lateral slot 13 opened on the adjustment plate 7. The lateral slot 13 is located below the upper support plate 5. A movable slot 25 matching the lateral slot 13 is opened on the upper support plate 5. A positioning screw 14 passing through the lateral slot 13 and the movable slot 25 is connected to the adjustment plate 7. A locking nut 15 is threaded on the positioning screw 14. A sliding limiter 12 matching one of the longitudinal slots 10 is fixed on the adjustment plate 7. When the hinge body is connected to the door panel, a horizontal slot (not shown) is opened on the door panel. A positioning screw 14 passing through the adjustment plate 7 and another longitudinal slot 10 is connected in the horizontal slot. A locking nut 15 is connected to the positioning screw 14. Specifically, this invention can also provide a transverse groove 13 located below the upper support plate 5 on the adjusting plate 7, and a movable groove 25 matching the transverse groove 13. The door panel 1 has a horizontal groove matching another longitudinal groove 10. Thus, when adjusting the longitudinal direction of the hinge body 2, the hinge body 2 slides directly in the longitudinal groove 10. When adjusting the lateral position of the hinge body 2, the adjusting plate 7 and the hinge body 2 are adjusted laterally as a whole. After adjustment, the locking nut 15 is tightened, and simultaneously, the screw 16 in the enlarged hole 8 and the adjusting groove are also tightened to the door. This method allows for simultaneous adjustment of the hinge body in both the horizontal and vertical directions, but the adjustment precision is not as high. Figures 3-7 The examples in the document are accurate.

[0043] In addition, such as Figure 10 As shown, the adjustment directions of the first and second adjustment structures of this utility model can be interchanged. That is, the first adjustment structure can be set as a horizontal adjustment structure, such as by setting a horizontal groove on the upper support plate. The second adjustment structure can be set as a vertical adjustment structure, such as by setting a vertical groove for adjustment and a positioning screw and nut on the adjustment plate, as well as multiple vertical grooves and screws for positioning. At the same time, the upper support plate and the lower support plate are provided with enlarged holes 8, which can also achieve the same bidirectional adjustment effect.

[0044] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
