Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a door hinge. Background Technology

[0002] A car door hinge is the connection mechanism between a car door and the car body. It is a mechanical device used to connect the car door and the car body and allow them to rotate relative to each other. A car door hinge includes a body fixing component, a door fixing component, and a connecting component. The connecting component is located between the body fixing component and the door fixing component. The connecting component includes a pin and a locking nut. One end of the pin passes through the side wall of one end of the body fixing component and the side wall of one end of the door fixing component. The locking nut is threaded and fixed to one end of the pin. Over time, the parts of the connecting component of the car door hinge will wear down, causing the car door to wobble during rotation. This necessitates the replacement of the car door hinge. However, the two ends of the car door hinge are fixed by bolts, which makes disassembly inconvenient and reduces the efficiency of car door hinge replacement. Utility Model Content

[0003] The purpose of this utility model is to provide a door hinge that addresses the defects and shortcomings of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The device includes a first fixing member, a second fixing member, and a connecting member. The connecting member is located between the first fixing member and the second fixing member. The first fixing member includes a first fixing part and a first mounting base. One end of the first fixing part is inserted into one end of the first mounting base. A buckle is rotatably connected to the side wall of the first mounting base. A fixing groove is provided on the side wall of the first fixing part for one end of the buckle to be engaged and fixed. A tension spring is provided between the side wall of the buckle and the side wall of the first mounting base. The tension spring drives one end of the buckle to be fixed in the fixing groove.

[0006] Preferably, the second fixing member includes a second fixing part and a second mounting base. The outer end of the second mounting base is provided with a placement groove. One end of the second fixing part is embedded in the placement groove. A limiting plate is provided on the side wall of the placement groove. The limiting plate restricts one end of the second fixing part in the placement groove. A locking component is provided in the side wall of the placement groove. The locking component can lock and fix one end of the second fixing part in the placement groove.

[0007] Preferably, the locking assembly includes a locking block and a compression spring. The second mounting base has a sliding groove on the side wall of the placement groove, and the locking block slides in the sliding groove. The side wall of the second fixing part has a locking groove, and the compression spring drives the outer end of the locking block to insert into the locking groove.

[0008] Preferably, the connector includes a pin and two locking buckles. The two ends of the pin pass through one end of the first fixing part and the second fixing part, respectively, and the two locking buckles are respectively fastened and fixed to the periphery of the two ends of the pin.

[0009] Preferably, a partition plate is provided in the middle of the pin, and one end of the first fixing part and one end of the second fixing part are respectively located at the upper and lower ends of the partition plate.

[0010] Preferably, the first fixing part is provided with a first stop plate at one end near the second fixing part, and the first stop plate can abut against one end of the second fixing part.

[0011] Preferably, the second fixing part is provided with a second stop plate at one end near the first fixing part, and the second stop plate can abut against the side wall of the first fixing part.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. When the parts inside the door hinge are worn and the door hinge needs to be replaced, the drive latch rotates, causing one end of the latch to disengage from the fixing groove. Then, one end of the first fixing part is pulled out from the first mounting seat. After that, the drive locking block slides into the sliding groove and compresses the compression spring, causing one end of the locking block to slide out from the locking groove. Then, the second fixing part disengages from the placement groove. At this time, the door hinge can be removed from the door and the vehicle body, which improves the convenience of removing the door hinge.

[0014] 2. When it is necessary to separate the first fixing part and the second fixing part, the two locking buckles are disengaged from both ends of the pin, and then one end of the first fixing part and the second fixing part are disassembled from both ends of the pin, which improves the convenience of disassembling the pin.

[0015] 3. Under the constraint of the first stop plate and the second stop plate, the first fixing part and the second fixing part can be restricted to a vertical or parallel position, thereby improving the stability between the first fixing part and the second fixing part.
