Technical Field
[0001] This utility model relates to the field of automotive component technology, specifically to a high-strength automotive door hinge. Background Technology
[0002] A car door hinge is a mechanical device, also known as a hinge, door hinge, or door hinge, mainly used to connect the car door and the car body to enable the door to open and close. It plays a vital role in the daily use of a car.
[0003] Existing car door hinges, due to the inability of the hinges to maintain a tight fit over time, are prone to deformation in certain parts after prolonged use and after possible collisions, scratches, or other accidents. Utility Model Content
[0004] To solve the above-mentioned problems, this utility model provides a high-strength automotive door hinge, which avoids the problem that existing automotive door hinges are prone to deformation after long-term use and after possible collisions, scratches and other accidents because the hinges cannot always maintain a tight fit.
[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a high-strength automotive door hinge, including a hinge seat one and a hinge seat two, a fixing device is slidably connected inside the hinge seat one, a fixing base is fixedly connected to the middle of the hinge seat one, a fixing block is rotatably connected inside the fixing base, a locking pin is fixedly connected to one side of the fixing block, rotating blocks are rotatably connected to the upper and lower parts of the fixing base, a connecting device is connected inside the rotating block, and the connecting device is fixedly connected to the hinge seat two;
[0006] The fixing device includes a sliding plate slidably connected inside the hinge seat, a connecting block fixedly connected to one side of the sliding plate, and a fixing plate fixedly connected to the side of the connecting block away from the sliding plate.
[0007] As an improvement, a sliding groove is provided on the side of the hinge seat near the sliding plate.
[0008] As an improvement, the hinge seat has multiple threaded holes inside, and the hinge seat is fixedly connected to the fixing plate by bolts.
[0009] As an improvement, the connecting device includes a stud fixedly connected to the rotating block, an ear seat fixedly connected to the middle of the stud, a connecting plate fixedly connected to one side of the ear seat, and the connecting plate fixedly connected to the hinge seat.
[0010] As an improvement, a groove is provided inside the hinge seat 2 on the side near the locking post.
[0011] As an improvement, the hinge seat is provided with multiple threaded holes at both ends.
[0012] The advantages of this utility model compared with the prior art are as follows: the fixing device enables the hinge seat one to match different car models, the connecting device fixes the hinge seat one and the hinge seat two together, and the locking post ensures that the hinge seat one and the hinge seat two are tightly connected. This avoids the problem that existing car door hinges are prone to deformation after long-term use due to the inability of the hinges to maintain a tight fit. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings.
[0017] In specific implementation, this utility model is combined with Figures 1 to 2 A high-strength automotive door hinge includes a hinge base 1 and a hinge base 2. A fixing device 2 is slidably connected inside the hinge base 1, so that the hinge base 1 is connected to the vehicle body. A fixing seat 3 is fixedly connected to the middle of the hinge base 1. A fixing block 4 is rotatably connected inside the fixing seat 3. A locking post 5 is fixedly connected to one side of the fixing block 4. The locking post 5 and the groove inside the hinge base 2 8 form a precise fit, further enhancing the stability and durability of the hinge.
[0018] The fixing device 2 includes a sliding plate 201 that is slidably connected inside the hinge seat 1. The hinge seat 1 is provided with a sliding groove on the side near the sliding plate 201. A connecting block 202 is fixedly connected to one side of the sliding plate 201. A fixing plate 203 is fixedly connected to the side of the connecting block 202 away from the sliding plate 201. Multiple threaded holes are provided inside the hinge seat 1. The hinge seat 1 is fixedly connected to the fixing plate 203 by bolts.
[0019] In the implementation of this utility model, the position of the sliding plate 201 is adjusted to adapt to different installation requirements of the hinge seat 1. The hinge seat 1 has multiple threaded holes pre-set inside. The fixing plate 203 is tightly locked to the hinge seat 1 by bolts, thereby realizing a stable connection between the hinge seat 1 and the vehicle body.
[0020] The upper and lower parts of the fixed base 3 are rotatably connected to rotating blocks 6. The rotating blocks 6 are internally connected to connecting devices 7. The connecting devices 7 are fixedly connected to the hinge base 2 8. The end of the hinge base 2 8 is provided with multiple threaded holes.
