[0029] The application will be further described below in conjunction with the drawings and embodiments.

[0030] First embodiment

[0031] Please refer to Figure 1 , Figure 2 and Figure 3 , among them, Figure 1 It is a structure diagram of the first embodiment of a new type of automobile door lock tight opening function structure provided by the application; Figure 2 It is a rear view of the door lock tight opening function structure shown in Figure 1 ; Figure 3 It is a front view of the door lock tight opening function structure shown in Figure 1 . A new type of automobile door lock tight opening function structure, comprising:

[0032] Connecting plate 1, opening push plate 2, fixed sleeve 3, transmission cylinder 4, unlocking stop drive arm 5, first rotating part 6, movable arm 14 and inner unlocking stop output arm 9;

[0033] The opening push plate 2 is arranged on the surface of the connecting plate 1;

[0034] The fixed sleeve 3 is arranged on one side of the connecting plate 1;

[0035] The transmission cylinder 4 is arranged inside the fixed sleeve 3;

[0036] The unlocking stop drive arm 5 is connected to one end of the connecting plate 1 through the first rotating part 6;

[0037] The movable arm 14 is arranged on the back of the connecting plate 1;

[0038] The inner unlocking stop output arm 9 is arranged on the back of the movable arm 14.

[0039] The surface of the opening push plate 2 is provided with an oval through slot 8.

[0040] The oval through slot 8 is used to provide position compensation during transmission, avoid movement interference between components, and ensure the smoothness of the action of the opening push plate 2.

[0041] The surface of the inner unlocking stop output arm 9 is provided with a mounting hole 10, and the inside of the mounting hole 10 is provided with a second rotating part 11.

[0042] The second rotating part 11 provides a stable rotating center for the inner unlocking stop output arm 9, and guarantees the accuracy of the rotating action.

[0043] The surface of the connecting plate 1 is provided with an arc-shaped movable groove 15.

[0044] The arc-shaped movable groove 15 is matched with the movement track of the opening push plate 2, provides guidance and limiting for the movement of the opening push plate 2, and prevents deviation during the movement.

[0045] The surface of the movable arm 14 is provided with a waist-shaped hole 7.

[0046] The waist-shaped hole 7 is used for adapting the stroke adjustment during transmission, so that the cooperation between the movable arm 14 and other components is more flexible, and the transmission requirements under different working conditions are met.

[0047] One end of the opening push plate 2 is connected with an outer opening output arm 13, and a reset torsional spring 12 is arranged between the opening push plate 2 and the movable arm 14.

[0048] The reset torsional spring 12 provides power support for the reset action of the structure, and guarantees the reset reliability after the function is realized.

[0049] Through the reasonable cooperation of the reset torsional spring 12, the fixed sleeve 3 and the inner unlocking stop output arm 9, the stable and reliable realization of the tension opening function is guaranteed, and the waist-shaped hole 7, the transmission cylinder 4, the arc-shaped movable groove 15 and the opening push plate 2 ensure the smoothness of the movement process, and the use performance and service life of the product are improved.

[0050] The working principle of the novel automobile door lock tension opening function structure provided by the application is as follows:

[0051] The inner unlocking stop output arm 9 rotates around the second rotating part 11 as the rotating center, the waist-shaped hole 7 on the surface of the inner unlocking stop output arm 9 is in sliding cooperation with the transmission cylinder 4 on the unlocking stop driving arm 5, power transmission is realized through the cooperation, and the unlocking stop driving arm 5 rotates synchronously around the first rotating part 6 as the rotating center.

[0052] When the door lock tension opening function is realized, the opening push plate 2 is fixed by the external structure and cannot rotate, at this time, the unlocking stop driving arm 5 rotates in the clockwise direction, and drives the inner unlocking stop output arm 9 to rotate in the counterclockwise direction through the cooperation of the transmission cylinder and the waist-shaped hole, since the fixed sleeve 3 and the opening push plate 2 remain relatively fixed, the fixed state of the opening push plate 2 makes the fixed sleeve 3 unable to rotate, and the inner unlocking stop output arm 9 rotates counterclockwise, which synchronously drives the reset torsional spring 12 to twist counterclockwise, and the reset torsional spring 12 is twisted and stores elastic potential energy due to being fixed at one end of the fixed sleeve 3.

[0053] When the fixed restriction of the opening push plate 2 is released, the reset torsional spring 12 releases the stored elastic potential energy, generates a reverse torque, drives the fixed sleeve 3 to rotate counterclockwise with the self-assembly limit as the rotation center, and stops until the fixed sleeve 3 reaches the limit position of the structure, and the whole tension opening function action cycle is completed.

[0054] In the conventional door lock opening working condition, the opening push plate 2 can smoothly slide along the arc-shaped movable slot 15 on the surface of the connecting plate 1, the outer opening output arm 13 synchronously transmits power with the action of the opening push plate 2, realizes the conventional opening function of the door lock, and the cooperation of the components is coordinated and there is no motion interference in the whole process.

[0055] Compared with the related art, the novel automobile door lock tension opening function structure has the following beneficial effects:

[0056] The novel automobile door lock tension opening function structure provided by the application cancels the unlocking stop conversion arm part in the traditional structure, reduces the number of transmission components, simplifies the mechanical structure and production process, reduces the product manufacturing cost, effectively reduces the overall weight of the structure, and realizes the lightweight design goal.
