[0002] At present, in the automotive field, car door locks are important components to ensure the safety of car doors. The door lock mechanisms on the market generally have only input but no output. This results in the need to set up an input mechanism and an output mechanism in the actual application process, which leads to a complex structure of the car door lock and increases the cost and installation difficulty of the car door lock. For example, the published patent 2022113589517 discloses a car door lock, a car door and a hugging door opening method, by respectively setting the front and rear inner opening handles at the front and rear positions of the inner side of the car door, and only when the two inner opening handles are pulled at the same time, that is, when the body of the door opener is in a state of turning towards the car door, can the car door be unlocked. When a single opening handle is pulled, the car door lock is in a semi-unlocked state and cannot be fully opened. Therefore, under the use and training of this hugging door opening method, the awareness of observing the situation behind the car before opening the car door is cultivated, and this kind of door opening habit is formed. However, the above structure still has only an input end and no output end, and still needs to be additionally installed with an output end in structure, which is more complicated in door lock arrangement and more expensive. Therefore, it is particularly important to solve the problem of complex structure and increased cost caused by the fact that ordinary car door locks only have an input end but no output end.

DETAILED DESCRIPTION

[0024] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0025] like Figure 1-2 As shown, this embodiment provides a multi-input and output door lock mechanism, including a card plate 1, a connecting rod 2, a pawl 3 and a gear 4, the pawl 3 is arranged on one side of the card plate 1, and the gear 4 is arranged above the pawl 3, characterized in that: a first rotating shaft 5 is also arranged in the mechanism, a first release rod 6 is arranged on the first rotating shaft 5, the connecting rod 2 is arranged on the upper end of the first release rod 6, a first opening 7 and a second opening 8 are opened on the first release rod 6, and the first opening 7 and the second opening 8 are respectively arranged at two positions on the first release rod 6. A second release rod 9 is arranged beside the pawl 3, a second rotating shaft 10 is arranged at one end of the second release rod 9, and a third opening 11 is arranged at the other end of the second release rod 9. A third release rod 12 is also arranged on the second rotating shaft 10, and the third release rod 12 is connected to the gear 4, and the gear 4 rotates through the third rotating shaft 13 to be connected to the third release rod 12. A fourth rotating shaft 14 is arranged beside the card plate 1, and a fourth release rod 15 is arranged on the fourth rotating shaft 14. A fifth rotating shaft 16 is disposed on the card plate 1 , and the card plate 1 rotates around the fifth rotating shaft 16 as an axis.

[0026] like Figure 6As shown, a hook-shaped feature 17 is provided on the connecting rod 2 , and a first auxiliary release rod 18 is also provided on the first release rod 6 .

[0027] like Figure 7 As shown, a special-shaped shaft 19 is provided on the connecting rod 2, and a special-shaped hole 20 is provided on the first release rod 6, and the special-shaped shaft 19 and the special-shaped hole 20 are matched and connected.

[0028] like Figure 8-9 As shown, a second auxiliary release lever 21 is provided on the second release lever 9. A cam structure 22 is provided on the gear 4, a third release lever first auxiliary lever 23 is provided on the end of the third release lever 12 close to the gear 4, a third release lever second auxiliary lever 24 is provided on the end of the third release lever 12 away from the gear 4, and a third release lever third auxiliary lever 25 is provided on one side of the third release lever 12 and the second auxiliary release lever 21 of the coaxial second release lever 9.

[0029] Each rotating shaft is equipped with a return spring to enable it to maintain or return to the initial position after movement.

[0030] like Figure 3 As shown, the working principle of the first release state is as follows: The first release rod 6 is provided with a second opening 8 for applying a pulling wire. By applying force in the direction of the arrow, the first release rod 6 rotates around the first rotating shaft 5 in the direction of the arrow, and the first opening 7 on the first release rod 6 also moves accordingly. A pulling wire can be installed on the first opening 7 to cause displacement.

[0031] The first release rod 6 has a special-shaped hole 20, which cooperates with the special-shaped shaft 19 on the connecting rod 2. When the first release rod 6 rotates according to the arrow, it also drives the connecting rod 2 to move. The hook-shaped feature 17 on the connecting rod 2 hooks the fourth release rod 15 to rotate it around the fourth rotating shaft 14. The fourth release rod 15 is coaxial with the pawl 3 and hard-connected, driving the pawl 3 to rotate in the release direction to disengage it from the card plate 1. The card plate 1 can be opened after it is disengaged from the pawl 3.

[0032] like Figure 4 As shown, the working principle of the second release state is as follows: The second release rod 9 is provided with a third opening 11 to apply a pulling wire, and a force is applied in the direction of the arrow, so that the second release rod 9 rotates around the second rotating shaft 10 in the direction of the arrow, and the second auxiliary release rod 21 on the second release rod 9 contacts the third release rod and the third auxiliary rod 25 on the third release rod 12. The second release rod 9 and the third release rod 12 are coaxial, and the second release rod 9 pushes the third release rod 12 to rotate in the direction indicated by the arrow, and the third release rod and the second auxiliary rod 24 contact the first auxiliary release rod 18, thereby pushing the first release rod 6 to rotate around the first rotating shaft 5, and the first opening 7 on the first release rod 6 also moves accordingly. A pulling wire can be installed on the first opening 7 to cause it to be displaced.

[0033] The first release rod 6 has a special-shaped hole 20, which cooperates with the special-shaped shaft 19 on the connecting rod 2. When the first release rod 6 rotates according to the arrow, it also drives the connecting rod 2 to move. The hook-shaped feature 17 on the connecting rod 2 hooks the fourth release rod 15 to rotate it around the fourth rotation axis 14. The fourth release rod 15 is coaxial with the pawl 3 and is hard-connected to drive the pawl 3 to rotate in the release direction to disengage it from the card plate 1. The card plate 1 can be opened after it is disengaged from the pawl 3.

[0034] like Figure 5 As shown, the working principle of the third release state is as follows: The gear 4 can be rotated in the direction of the arrow by external power. The cam feature 22 on the gear 4 conflicts with the third release lever and the first auxiliary lever 23. The third release lever and the first auxiliary lever 23 drive the third release lever 12 to rotate around the second rotation axis 10 in the direction of the arrow. The third release lever and the second auxiliary lever 24 conflicts with the first auxiliary release lever 18, thereby pushing the first release lever 6 to rotate around the first rotation axis 5.

[0035] The first opening 7 on the first release rod 6 also moves accordingly, and a pull wire can be installed on the first opening 7 to cause it to move. The first release rod 6 has a special-shaped hole 20, which cooperates with the special-shaped shaft 19 on the connecting rod 2. When the first release rod 6 rotates according to the arrow, it also drives the connecting rod 2 to move. The hook-shaped feature 17 on the connecting rod 2 hooks the fourth release rod 15 to rotate it around the fourth rotating shaft 14. The fourth release rod 15 is coaxial with the pawl 3 and is hard-connected to drive the pawl 3 to rotate in the release direction to disengage it from the card plate 1. The card plate 1 can be opened after it is disengaged from the pawl 3.

[0036] 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.
