Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a hinge that is easy to replace. Background Technology

[0002] Currently, the opening mechanism for car trunk lids typically combines a bow-shaped hinge and a torsion spring. The bow-shaped hinge includes a hinge support, a fixing pin 1, a fixing pin 2, a buffer block, a connecting rod, and a hinge rod. The hinge support is fastened to the car frame with bolts, and the hinge rod is connected to the trunk lid with bolts. The torsion spring is fixed through slots on the hinge support and the connecting rod. The torsion spring has a certain torsional torque. After the trunk lid is unlocked, the torsion spring releases its torsional force and pushes the hinge rod through the connecting rod, thereby allowing the trunk lid to be pre-opened to a certain angle.

[0003] Over time, hinges can wear out significantly, potentially leading to increased friction noise and other issues. In such cases, hinges need to be replaced. However, since they are bolted to the door and body, replacement requires considerable force or the use of power tools, making disassembly inconvenient and replacement inefficient.

[0004] Therefore, we now offer an easy-to-replace hinge that eliminates the drawbacks of existing devices. Summary of the Invention

The hinge support 100 and the hinge rod 600 are provided with fixing holes 102. The first connecting plate 101 and the second connecting plate 601 are provided with insertion holes 103 corresponding to the fixing holes 102. The second connecting plate 601 is provided with a clamping mechanism for limiting the hinge support 100 and the hinge rod 600. The hinge support 100 and the hinge rod 600 are provided with fixing units for fixing the first connecting plate 101 and the second connecting plate 601. The first connecting plate 101 is fixedly connected to the car frame, and the second connecting plate 601 is fixedly connected to the car rear cover. The clamping mechanism clamps and limits the hinge support and the hinge rod on the first connecting plate and the second connecting plate, and then fixes them with fixing units, which facilitates installation and disassembly. The torsion spring is fixed on the hinge support and the connecting rod. The torsion spring has a certain torsional torque. After the car rear cover is unlocked, the torsion spring releases the torsional force and pushes the hinge rod through the connecting rod, thereby realizing the pre-opening of the car rear cover to a certain angle.

[0024] In this embodiment, as Figure 3As shown, the clamping mechanism includes a bidirectional screw 701, which is disposed in a groove 702 in the first connecting plate 101 and the second connecting plate 601. One end of the bidirectional screw 701 is rotatably connected to the inner wall of the groove 702, and the other end of the bidirectional screw 701 is fixedly connected to a knob 703 outside the groove 702. Two sliders 704 are threadedly connected to the outer end of the bidirectional screw 701. The sliders 704 are slidably connected in the groove 702. Block 704 is fixedly connected to clamping plate 705 outside slide groove 702. When clamping is required, turn knob 703. Knob 703 drives bidirectional screw 701 to rotate. Bidirectional screw 701 drives two sliders 704 to move closer to each other, clamping hinge support 100 and hinge rod 600. When disassembly is required, simply turn knob 703 in the opposite direction. Bidirectional screw 701 rotates, driving the two sliders 704 to move away from each other, thereby releasing hinge support 100 and hinge rod 600.

[0025] In one embodiment, such as Figure 2 As shown, the fixing unit includes a pin 801. The outer end of the pin 801 contacts the surfaces of the fixing hole 102 and the insertion hole 103. A through hole 802 is provided in the pin 801. An annular protrusion 803 is fixedly connected to the inner surface of the through hole 802. A limiting rod 804 is slidably connected in the through hole 802. One end of the limiting rod 804 is fixedly connected to a button 805, and the other end of the limiting rod 804 is provided with a limiting groove 806. A spring 807 is provided at the outer end of the limiting rod 804. One end of the spring 807 is fixedly connected to the button 805, and the other end of the spring 807 is fixedly connected to the annular protrusion 803. Two spheres 808 are provided at the limiting groove 806. The pin 801 is provided with... The ball 808 is connected to the movable groove 809. The surface of the insertion hole 103 is provided with a first slot 810 that is connected to the ball 808. When installing the hinge support 100 and the hinge rod 600, the fixing hole 102 and the insertion hole 103 are aligned, and then the insertion post 801 is inserted into the fixing hole 102 and the insertion hole 103. The ball 808 cooperates with the first slot 810 to fix the hinge support 100 to the first connecting plate 101 and the hinge rod 600 to the second connecting plate 601. When disassembly is required, the button 805 is pressed. The button 805 drives the limiting rod 804 to move downward and compresses the spring 807. The ball 808 retracts into the limiting groove 806, and the insertion post 801 can be pulled out to remove the hinge.

[0026] In one embodiment, such as Figure 3 As shown, the outer end of the knob 703 is provided with anti-slip texture 901, which increases the friction between the finger and the knob 703, prevents slippage, and makes it easier to fix and disassemble the hinge.

[0027] In one embodiment, such as Figure 3As shown, a rubber pad 902 is fixedly connected to the side of the clamping plate 705 that contacts the hinge support 100 and the hinge rod 600 to increase friction, making the clamping more stable and protecting the surfaces of the hinge support 100 and the hinge rod 600 from scratches.

[0028] In one embodiment, such as Figure 1 As shown, the hinge support 100 and the connecting rod 500 are provided with a second slot 903 for fixing the torsion spring. The torsion spring is fixed by the second slot 903 on the hinge support 100 and the connecting rod 600. The torsion spring has a certain torsional torque. After the car rear cover is unlocked, the torsion spring releases the torsional force and pushes the hinge rod 600 through the connecting rod 500, thereby realizing the pre-opening of the car rear cover to a certain angle.

[0029] In one embodiment, such as Figure 1 and Figure 3 As shown, the two clamping plates 705 are symmetrically arranged on both sides of the hinge support 100 and the hinge rod 600, making the clamping of the hinge support 100 and the hinge rod 600 more stable.

[0030] In one embodiment, such as Figure 1 As shown, a buffer block 400 is fixedly connected to the side of the hinge rod 600 away from the connecting rod 500. When the car trunk is opened, the buffer block 400 can play a certain role in buffering and protecting the hinge rod 600 from directly colliding with the car.

[0031] The above embodiments disclose a hinge that is easy to replace. When installing the hinge, rotating the knob 703 causes the bidirectional screw 701 to rotate. The bidirectional screw 701 causes the two sliders 704 to move closer together, clamping the hinge support 100 and the hinge rod 600. The fixing hole 102 and the insertion hole 103 are aligned. Then, the insertion post 801 is inserted into the fixing hole 102 and the insertion hole 103. The ball 808 engages with the first slot 810, connecting the hinge support 100 to the first connecting plate. 101 is fixed to the hinge rod 600 and the second connecting plate 601. When disassembly is required, press button 805. Button 805 moves the limit rod 804 downward and compresses the spring 807. The ball 808 retracts into the limit groove 806, and the insert 801 can be pulled out. Rotate knob 703 in the opposite direction. The bidirectional screw 701 rotates, causing the two sliders 704 to move away from each other, thereby loosening the hinge support 100 and the hinge rod 600, which facilitates disassembly and installation and improves the efficiency of replacement.
