DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 5 The utility model provides a technical solution: a lightweight panel for the inner door of an automobile. It includes a functional end 1 and a fixed end 2, the fixed end 2 is fixedly installed on one side of the functional end 1, a connector 3 is fixedly installed on the surface of the fixed end 2, a slide rail 4 is provided on the other side of the functional end 1, a slider 5 is slidably installed on the inner wall of the slide rail 4, a clamping block 8 is slidably installed on the surface of the slider 5, a connecting spring 9 is fixedly installed between the clamping block 8 and the slider 5, a limit plate 6 is slidably installed on the surface of the functional end 1, a plurality of stop bars 7 arranged in sequence are fixedly installed at the bottom of the limit plate 6, a plurality of openings are provided on the surface of the slide rail 4 and are aligned with the stop bars 7, a slot is provided on the top of the slider 5, and the neatly combed wire harness is clamped into the clamping block 8 to prevent the wire harness from shaking and producing abnormal noise.

[0023] A spring is arranged between the limit plate 6 and the functional end 1. The cross section of the stop rod 7 is adapted to the opening on the surface of the slide rail 4 and the slot on the top of the slider 5. After the stop rod 7 moves into the slot, the slider 5 is restricted so that the slider 5 cannot move.

[0024] A spring piece 10 is slidably installed on the surface of the slider 5, a pull rod 12 is fixedly installed on the surface of the spring piece 10, a fixed plate 13 is fixedly installed on the inner wall of the fixed end 2, a blade 14 is fixedly installed on the inner wall of the fixed end 2, and a traction rope 15 is sleeved on a section of the fixed plate 13 and the pull rod 12 away from the spring piece 10. When the traction rope 15 breaks, the pull rod 12 pops out under the elastic force of the elastic member.

[0025] An elastic member is arranged between the spring piece 10 and the slider 5 . A plurality of fixing plates 13 and blades 14 are arranged in sequence. When the door is hit, the panel will deform to displace the blade 14 , and the displaced blade cuts the traction rope 15 .

[0026] Trapezoidal plates 11 are fixedly installed on the top and bottom of the spring piece 10 and the side surfaces are set as inclined surfaces. The position of the clamping block 8 close to the inclined surface of the trapezoidal plate 11 is also set as an inclined surface. When the spring piece 10 pops out, it will drive the trapezoidal plate 11 to move, and the moving trapezoidal plate 11 will squeeze the bottom inclined surface of the clamping block 8 to open the clamping block 8.

[0027] A rubber pad 16 is fixedly mounted on the surface of the functional end 1 to prevent the wiring harness from being squeezed and damaged when the panel is deformed.

[0028] When working, align the connecting piece 3 with the docking port on the door inner panel and insert it into the docking port so that the panel is installed on the surface of the vehicle door inner panel. The panel can increase the impact resistance of the vehicle door. After installation, the wiring harness of the electronic components in the vehicle door inner panel is neatly combed and then clamped into the clamping block 8. The distance between the clamping blocks 8 can be adjusted according to the number of wiring harnesses. At the same time, the horizontal position of the clamping block 8 can be adjusted according to the installation angle of the wiring harness. After lifting the limit plate 6, the moving limit plate 6 drives the stopper 7 to leave the slot on the surface of the slider, and the limit on the slider 5 is released. At this time, the slider 5 can be moved left and right to determine where the combed wiring harness needs to be fixed, and the limit plate 6 is lowered. The moving limit plate 6 drives the stopper 7 to move into the slot, limiting the slider 5 so that the slider 5 cannot shake, so that the clamping block 8 fixes the wiring harness of the electronic components in the vehicle door inner panel, avoiding the shaking of the vehicle body during the movement of the vehicle, driving the wiring harness to shake, causing abnormal noise at the door inner panel, interfering with the normal driving of the driver, and also affecting the quietness of the driver and passengers.

[0029] When the door is hit in an emergency, the strong impact will cause the inner door panel to deform. The deformed door panel squeezes the panel to bend the fixed end 2. The bent fixed end 2 causes the blade 14 to shift instantly. The shifted blade 14 contacts and cuts off the traction rope 15. The broken traction rope no longer pulls the pull rod 12. The pull rod 12 releases its elastic potential energy under the elastic force of the elastic member and pops out. The popped-out pull rod 12 causes the spring piece 10 to pop out, pushing the wiring harness stuck in the clamp block 8 away from the functional end 1, so as to avoid the panel body being squeezed and deformed instantly by the impact, causing damage to the wiring harness. At the same time, the popped-out spring piece 10 drives the trapezoidal plate 11 to move. The moving trapezoidal plate 11 squeezes the inclined surface of the clamp block 8 to push the clamp block 8 to move, so as to open the clamp block 8, so that the spring piece 10 can effectively pop out the wiring harness.

[0030] If the inner panel 1 is deformed and contacts the wiring harness, the rubber pad 16 can mitigate a portion of the impact force, thereby preventing the inner panel 1 from deforming and squeezing the wiring harness and damaging the wiring harness, thereby reducing the maintenance cost of the vehicle after an accident.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
