DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0023] Embodiment 1:

[0024] like Figure 1-4As shown in the figure, the mechanical trunk lid automatic hinge mechanism provided by the utility model comprises: a hinge 3 for connecting a vehicle body 1 and a trunk lid 2, a plurality of hinges 3 are provided, two driving mechanisms are provided between the vehicle body 1 and the trunk lid 2, and the driving mechanisms are provided at two sides of the trunk on the vehicle body 1; the driving mechanism comprises an electric telescopic rod 4, and the electric telescopic rod 4 adopts a structure commonly used in current electric tailgates of automobiles, and its specific structure is not repeated here, and the electric telescopic rod 4 is controlled by a switch or other control device (such as an inductive electric tailgate, a voice-activated electric tailgate, etc. on existing vehicles) The electric tailgate control method controls its automatic extension and retraction, and the two ends of the electric telescopic rod 4 are respectively connected to the vehicle body 1 and the trunk lid 2 through a connecting assembly 5; the connecting assembly 5 includes a mounting frame 6, and the mounting frame 6 is connected to the vehicle body 1 or the trunk lid 2 through bolts. A plug-in tube 7 is rotatably installed on the mounting frame 6, and the bottom end of the plug-in tube 7 is closed. Connecting shafts 15 are installed on both sides. The connecting shaft 15 is rotatably connected to the mounting frame 6, so that the mounting frame 6 is rotatably connected to the plug-in tube 7. Both ends of the electric telescopic rod 4 are installed with plug connectors 8, and the side of the plug connector 8 is provided with The limit groove 9 is provided, the plug connector 8 is inserted into the plug tube 7, a limit pin 10 is installed on the side of the plug tube 7, a pull ring is installed on the limit pin 10, one end of the limit pin 10 is inserted into the limit groove 9, the plug connector 8 is limited, and the plug connector 8 is prevented from coming out of the plug tube 7. When in use, the electric telescopic rod 4 receives a control signal, and the control signal can be triggered by a switch or other measures, which will not be described in detail here, so that the electric telescopic rod 4 is powered on and started. When the electric telescopic rod 4 automatically extends, the trunk cover 2 is rotated with the hinge 3 as the axis, so that the trunk cover 2 is automatically opened. On the contrary, the trunk lid 2 is automatically closed. When the electric telescopic rod 4 needs to be replaced, the pull ring on the limit pin 10 is pulled out of the limit pin 10 in the limit groove 9, thereby releasing the limit on the plug connector 8, and the plug connector 8 is pulled out from the plug tube 7, so that the electric telescopic rod 4 can be easily removed. At the same time, the control line of the electric telescopic rod 4 can be removed, and then a new electric telescopic rod 4 can be installed and the control line can be connected to complete the replacement of the electric telescopic rod 4. No tools are required during the replacement process, and the disassembly and connection process is convenient and fast, which is conducive to popularization and use.

[0025] By providing a hinge 3 and a driving mechanism including an electric telescopic rod 4 and a connecting assembly 5, a plug connector 8 is inserted into a plug tube 7 to connect the mounting frame 6 with the electric telescopic rod 4, and a limiting pin 10 is inserted into a limiting groove 9 to limit the plug connector 8, so that the electric telescopic rod 4 can be conveniently disassembled and replaced with a new one, thereby reducing the time for repairing the driving mechanism and improving the repair efficiency.

[0026] Embodiment 2:

[0027] like Figure 3-4As shown, the bottom end of the plug connector 8 is provided with a chamfer, which is a 45-degree chamfer with a length of 5-8 mm. When in use, the bottom end of the plug connector 8 is aligned with the plug tube 7 for insertion. Since the plug connector 8 has a large chamfer, the bottom end diameter of the plug connector 8 is much smaller than the diameter of the plug tube 7. Therefore, the plug connector 8 is easier to insert into the plug tube 7, shortening the time required for plugging the two together.

[0028] By providing a chamfer at the bottom end of the plug connector 8 , it is possible to facilitate the plug connector 8 to be aligned with the plug tube 7 and inserted, thereby facilitating the plugging of the plug connector 8 and the plug tube 7 .

[0029] Embodiment 3:

One end of the limit pin 10 passes through the guide tube 11, and a return spring 12 in a compressed state is sleeved on the limit pin 10. The two ends of the return spring 12 are respectively connected to the limit pin 10 and the guide tube 11. When the limit pin 10 is pulled outward, the limit pin 10 moves outward in the guide tube 11, thereby compressing the return spring 12 until the end of the limit pin 10 is disengaged from the limit groove 9. The limit pin 10 is released, and under the action of the return spring 10, the limit pin 10 moves in the direction close to the center of the plug tube 7, so that the limit pin 10 is inserted into the limit groove 9 opened on the plug connector 8. Under the action of the return spring 12, the limit pin 10 is not easy to fall out of the limit groove 9.

[0031] By providing the guide tube 11 and the return spring 12 , the compressed return spring 12 can be used to prevent the end of the limit pin 10 from escaping from the limit groove 9 , thereby playing a limiting role.

[0032] Embodiment 4:

[0033] like Figure 4 As shown, a positioning strip 13 is installed in the plug tube 7, and a positioning groove 14 matched with the positioning strip 13 is provided on the plug connector 8. The positioning groove 14 is opened along the axial direction of the plug connector 8. When in use, the positioning groove 14 on the plug connector 8 is aligned with the positioning strip 13, and then the plug connector 8 is inserted into the plug tube 7 until the bottom end of the plug connector 8 touches the bottom end blockage of the plug tube 7. At this time, the limit pin 10 is just aligned with the limit groove 9, which facilitates the limit pin 10 to be inserted into the limit groove 9.

[0034] By providing the positioning strip 13 and the positioning groove 14 , the positional relationship between the plug connector 8 and the plug tube 7 can be positioned, so as to facilitate the plugging of the limiting pin 10 and the limiting groove 9 .

[0035] Embodiment 5:

[0036] A gasket is installed at the bottom end of the mounting frame 6. The gasket is made of rubber. When the mounting frame 6 is connected to the vehicle body 1 or the trunk lid 2 by bolts, the gasket blocks the connection between the two, which is beneficial to reduce the wear of the contact surface and reduce the possibility of rust.

[0037] By providing a mounting gasket at the bottom end of the mounting frame 6, it is helpful to reduce the wear of the contact surface and reduce the possibility of rust.

[0038] Working principle: When in use, the electric telescopic rod 4 receives a control signal, so that the electric telescopic rod 4 is powered on and started, and then the electric telescopic rod 4 automatically extends or shortens (taking extension as an example below), so that the trunk lid 2 rotates with the hinge 3 as the axis, so that the trunk lid 2 is automatically opened, and vice versa, the trunk lid 2 is automatically closed. When the electric telescopic rod 4 needs to be replaced, pull the pull ring on the limit pin 10, pull the limit pin 10 out of the limit groove 9, and then release the limit on the plug connector 8, pull the plug connector 8 out of the plug tube 7, and then the electric telescopic rod 4 can be easily removed. At the same time, the control line of the electric telescopic rod 4 can be removed, and then a new electric telescopic rod 4 can be installed and the control line can be connected to complete the replacement of the electric telescopic rod 4. No tools are required during the replacement process, and the disassembly and connection process is convenient and fast, which is conducive to popularization and use.
