Detailed description of the invention
Embodiments provide a kind of sedan tail door self closing device, high for the functional realiey cost solving existing car electric tail gate, baroque technical problem.
For making goal of the invention of the present invention, feature, advantage can be more obvious and understandable, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, the embodiments described below are only the present invention's part embodiments, and the embodiment of not all.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, in the embodiment of the present invention, a kind of sedan tail door self closing device comprises: motor 12, reduction box 11, worm mechanism, the first transmission guide rod 7, second transmission guide rod 10, first bracing wire assembly 6 and the second bracing wire assembly 15.This motor 12 is connected with worm mechanism by reduction box 11, and when motor 12 works, the high-speed rotation that reduction box 11 makes motor 12 export becomes and slowly runs, but torsion enhancing, then transmission drive worm mechanism to slowly run.This first transmission guide rod 7 and the second transmission guide rod 10 correspondence are arranged, and are provided with this worm mechanism between the two.The inner side of the first transmission guide rod 7 and the second transmission guide rod 10 is provided with screw thread, engages each other with the screw thread that this worm mechanism is arranged.
One end of this first bracing wire assembly 6 is connected with the connecting rod of sedan tail door side, and the other end is connected with this first transmission guide rod 7; One end of this second bracing wire assembly 15 is connected with the connecting rod of sedan tail door opposite side, and the other end is connected with this second transmission guide rod 10.
This sedan tail door self closing device operationally, motor 12 drives worm mechanism to rotate by reduction box 11, the first transmission guide rod 7 engaged with worm mechanism and the second transmission guide rod 10 are respectively to moving right, being moved to the left, thus drive the first bracing wire assembly 6 on it and the second bracing wire assembly 15 to move right in the lump, be moved to the left, stay cord 14 on two bracing wire assemblies shrinks, because stay cord 14 two ends is fixed on the connecting rod of sedan tail door, thus sedan tail door is closed.Otherwise when motor 12 rotates backward, the first bracing wire assembly 6 and the second bracing wire assembly 15 extend, and bracing wire assembly is in releasing orientation, then sedan tail door can be opened at any time.It should be noted that, by the first bracing wire assembly 6 and the second bracing wire assembly 15 and the different settings of the annexation between sedan tail door connecting rod, also can make, when motor 12 works, when stay cord 14 shrinks, sedan tail door is opened; And stay cord 14 is when stretching, sedan tail door is in releasing orientation.
Wherein, this worm mechanism specifically can comprise main worm screw 9 and secondary worm screw 8, as shown in Figure 2.Main worm screw 9 is connected with reduction box 11, and main worm screw 9 is connected by helical teeth or straight-tooth and secondary worm screw 8, thus when reduction box 11 drives main worm screw 9 to rotate, main worm screw 9 also drives secondary worm screw 8 to rotate.Wherein, main worm screw 9 and the first transmission guide rod 7 engage each other, and secondary worm screw 8 and the second transmission guide rod 10 engage each other.
Preferably, this motor 12 and reduction box 11 can be arranged in motor connecting box 2, and one end of this motor connecting box 2 is provided with motor attachment cap 1, and this motor attachment cap 1 is provided with power connector 13.And the other end of motor connecting box 2 is fixedly connected with transmission shell 3, it is inner that this worm mechanism, the first transmission guide rod 7, second transmission guide rod 10, first bracing wire assembly 6 and the second bracing wire assembly 15 are installed in this transmission shell 3.This transmission shell 3 specifically can also be divided into upper cover 4 and lower cover 5, as shown in Figure 4.
Under a certain application-specific scene, as shown in Figure 5, this sedan tail door self closing device laterally can be arranged on the inside of car trunk, and two ends are connected with the swing arm connecting rod of sedan tail door with the stay cord 14 on the second bracing wire assembly 15 respectively by the first bracing wire assembly 6.Operationally, by operating the key switch of car key remote controller or automobile tail gate, energising controls the rotating of motor 12, motor 12 drives major and minor worm screw 8 to rotate by exporting after reduction box 11, allowing transmission guide rod move left and right inside transmission shell 3 makes stay cord 14 shrink, thus realizes the closedown of sedan tail door.
In the present embodiment, this sedan tail door self closing device can drive the stay cord 14 on bracing wire assembly to shrink by motor 12 rotating, thus realizes the action of closing the door of sedan tail door, with low cost, structure simple, filled up the vacancy of car electric tail gate function.
Above a kind of sedan tail door self closing device provided by the present invention is described in detail, for one of ordinary skill in the art, according to the thought of the embodiment of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
