Detailed implementation manners

[0035] Reference is made below to Figures 1 - 10 describe the child lock mechanism 100 according to the embodiment of the first aspect of the present utility model.

[0036] As Figures 1 - 10 shown, the child lock mechanism 100 according to the embodiment of the first aspect of the present utility model includes a rocker arm 1, a connecting arm 2 and a rotating pin 3.

[0037] Specifically, a first chute 11 is formed on the rocker arm 1. The first chute 11 includes a first sub-chute 111 and a second sub-chute 112 that communicate with each other. The first sub-chute 111 extends along a first direction (for example, Figure 5 the left-right direction in Figure 5 ), and the second sub-chute 112 extends along a second direction (for example,

[0038] The guiding groove 21 and the first sub-groove 111 at least partially overlap. One end of the rotating pin 3 is fitted in the guiding groove 21. The guiding groove 21 guides the movement of the rotating pin 3. The rotating pin 3 can move in the guiding groove 21 along the first direction, so that the other end of the rotating pin 3 can be switched between the first sub-groove 111 and the second sub-groove 112, thereby completing the separation or combination between the connecting arm 2 and the rocker arm 1, that is, completing the switching of the child lock mechanism 100 between the unlocked state and the locked state. At the same time, both the rocker arm 1 and the connecting arm 2 are fitted with the rotating pin 3, which is beneficial to restricting the rotating pin 3 and preventing the rotating pin 3 from tilting during movement, improving the use stability of the rotating pin 3, and thus improving the stability and smoothness of the switching of the child lock mechanism 100 between the unlocked state and the locked state, and avoiding the risk that the child lock mechanism 100 cannot be unlocked.

[0039] The child lock mechanism 100 is switchable between the unlocked state and the locked state. As Figure 9 shown, when the child lock mechanism 100 is in the unlocked state, the rotating pin 3 is away from the second sub-groove 112, that is, the connecting arm 2 and the rocker arm 1 are combined. The rotation of the rocker arm 1 can drive the rotation of the connecting arm 2, so that the operation of opening or closing the door can be realized through the door handle; as Figure 10 shown, when the child lock mechanism 100 is in the locked state, the rotating pin 3 is arranged in the second sub-groove 112, that is, the rocker arm 1 and the connecting arm 2 are separated. The rocker arm 1 rotates along the second direction, and the movement of the second sub-groove 112 makes the rotating pin 3 fit in different positions in the extending direction of the second sub-groove 112, while the position of the rotating pin 3 in the guiding groove 21 remains unchanged, that is, the rocker arm 1 rotates idly, so that the connecting arm 2 cannot rotate with the rotation of the rocker arm 1, thereby effectively avoiding the risk of the door being opened due to a child accidentally pulling the door handle during riding. At the same time, when the child lock is in the locked state, a force is applied to the rocker arm 1 through the door handle, and the rocker arm 1 moves along the second direction, which can prevent the user from applying a force to the door handle to impact the child lock mechanism 100, thereby avoiding damage to the child lock mechanism 100 and further extending the service life of the child lock mechanism 100.

[0040] For the child lock mechanism 100 according to the embodiment of the present invention, through the cooperation of the rotating pin 3 in the first sliding groove 11 of the rocker arm 1 and the guiding groove 21 of the connecting arm 2, the tilting of the rotating pin 3 during rotation is avoided, the use stability of the rotating pin 3 is improved, the stability and smoothness of the switching of the child lock mechanism 100 between the unlocked state and the locked state are improved, and the risk that the child lock mechanism 100 cannot be unlocked is avoided.

[0041] According to some embodiments of the present invention, referring to Figure 4 and Figure 5, at least part of the rocker arm 1 is spaced apart from the connecting arm 2, and one end of the rotating pin 3 passes through the guiding groove 21 and is in sliding fit with the first sliding groove 11. At least part of the rocker arm 1 being spaced apart from the connecting arm 2 provides an installation space for the rotating pin 3, increases the smoothness of the sliding of the rotating pin 3 in the guiding groove 21 and the first sliding groove 11, and at the same time reduces the contact area between the rocker arm 1 and the connecting arm 2, reducing the frictional resistance between the rocker arm 1 and the connecting arm 2, thereby increasing the smoothness of the relative rotation of the rocker arm 1 and the connecting arm 2 and enhancing the fluency of the switching of the child lock mechanism 100 between the unlocked state and the locked state.

[0042] Further, as Figure 5 shown, the rocker arm 1 includes a first connecting section 13, a second connecting section 14, and a third connecting section 15. The first connecting section 13 is rotatably connected to the connecting arm 2 coaxially. The second connecting section 14 is connected to the first connecting section 13, and the second connecting section 14 extends in a direction away from the connecting arm 2. The third connecting section 15 is connected to the second connecting section 14, and the third connecting section 15 extends in a direction away from the first connecting section 13, and a first sliding groove 11 is formed on the third connecting section 15. Thus, the first connecting section 13 is used for rotatably connecting to the connecting arm 2 coaxially, and the second connecting section 14 extends in the thickness direction of the rocker arm 1 away from the first connecting section 13 to facilitate spacing the third connecting section 15 and the connecting arm 2, thereby facilitating the spacing of at least part of the rocker arm 1 and the connecting arm 2.

[0043] According to some embodiments of the present invention, the rocker arm 1 includes a rocker arm body and a rib (not shown in the figure). The first sliding groove 11 is formed on the rocker arm body. The rib is provided on a side of the rocker arm body adjacent to the connecting arm 2, the rib and the first sliding groove 11 are spaced apart in a first direction, and the rib is in contact with the connecting arm 2. The rib may be provided circumferentially on the rocker arm body, or circumferentially at a position corresponding to the position where the rocker arm body is rotatably connected to the connecting arm 2 coaxially. The rib may be multiple, and the multiple ribs are spaced apart circumferentially at the position where the rocker arm is rotatably connected to the connecting arm 2 coaxially, or the rib is one, and the rib is provided annularly on the rocker arm body. No specific limitation is made here. The side of the rib away from the rocker arm 1 is adapted to contact the surface of the connecting arm 2 to use the rib to space the rocker arm 1 and the connecting arm 2 apart.

[0044] Optionally, the rib may also be provided on the connecting arm 2. Specifically, the rib is provided along the circumferential direction of the connecting arm 2, and the side of the rib away from the connecting arm 2 is adapted to contact the surface of the rocker arm 1 to use the rib to space at least part of the rocker arm 1 and the connecting arm 2 apart.

[0045] Optionally, ribs are provided on both the rocker arm 1 and the connecting arm 2, and the two ribs face each other to space at least part of the rocker arm 1 and the connecting arm 2 apart.

[0046] In addition, referring to Figures 1 - 3 , and combining with Figure 9 and Figure 10, a mounting groove 16 is formed on the rocker arm 1. The child lock mechanism 100 further includes an elastic reset member 4 and a push rod 5. One end of the elastic reset member 4 is installed in the mounting groove 16. The push rod 5 is arranged on the side of the connecting arm 2 adjacent to the rocker arm 1, and the push rod 5 is connected to the other end of the elastic reset member 4. When the child lock mechanism 100 is in the unlocked state, the push rod 5 contacts the rocker arm 1. When the child lock mechanism 100 is in the unlocked state, the push rod 5 pushes the rocker arm 1, and the elastic reset member 4 rotates around its connection position with the push rod 5 to form a rotational force, that is, the elastic reset member 4 deforms as the rocker arm 1 rotates; when the acting force of the push rod 5 on the rocker arm 1 is removed, the force for the elastic reset member 4 to restore deformation causes the rocker arm 1 to return to its previous position. Thus, the elastic reset member 4 is beneficial to restricting the rotation angle of the rocker arm 1 and at the same time enabling the rocker arm 1 to reliably return to its previous position, thereby improving the use stability of the child lock mechanism 100 and prolonging the service life of the child lock mechanism 100.

[0047] Wherein, the mounting groove 16 is arc-shaped, which is convenient for the installation of the elastic reset member 4 in the mounting groove 16. However, it is not limited thereto. Optionally, the elastic reset member 4 is a spring member. However, it is not limited thereto.

[0048] Furthermore, referring to Figures 1 - 3 , and combining with Figure 6 , the push rod 5 includes a first mounting portion 51, a second mounting portion 52 and a third mounting portion 53. The first mounting portion 51 is adapted to be rotatably connected to the door hinge. The second mounting portion 52 is arranged on the side of the first mounting portion 51 away from the rocker arm 1, and the second mounting portion 52 is adapted to be connected to the door handle. The third mounting portion 53 is arranged on the side of the first mounting portion 51 adjacent to the rocker arm 1, and the third mounting portion 53 contacts the rocker arm 1.

[0049] In the direction away from the rocker arm 1, the third mounting portion 53, the first mounting portion 51 and the second mounting portion 52 are connected in sequence. The user can make the push rod 5 rotate around the door hinge through the door handle, and the third mounting portion 53 transmits the acting force to the surface of the rocker arm 1 to rotate the rocker arm 1.

[0050] The cross-sectional shape of the third mounting portion 53 is arc-shaped, which is beneficial to ensuring the contact between the push rod 5 and the rocker arm 1 during rotation, thereby improving the stability of the push rod 5 transmitting the acting force to the rocker arm 1.

[0051] According to some embodiments of the present invention, such as Figures 1 - 3 ,, and Figures 7 - 10, the child lock mechanism 100 further includes a driving arm 6, a driving gear 7, and a driving member 8. The driving arm 6 is provided on a side of the swing arm 1 away from the connecting arm 2. A second chute 611 is formed on the driving arm 6, and the rotating pin 3 is slidably engaged with the second chute 611. A third chute 71 is formed on the driving gear 7, and the driving arm 6 is slidably engaged with the third chute 71. The output shaft 81 of the driving member 8 has a gear portion 82, and the gear portion 82 meshes with the driving gear 7. Thus, the acting force is transmitted between the driving member 8 and the driving gear 7 through the engagement between the gear portion 82 and the driving gear 7, the acting force is transmitted between the driving gear 7 and the driving arm 6 through the cooperation between the driving arm 6 and the third chute 71, and the acting force is transmitted between the driving arm 6 and the rotating pin 3 through the cooperation between the rotating pin 3 and the second chute 611.

[0052] When the child lock mechanism 100 switches between the unlocked state and the locked state, the driving member 8 drives the driving gear 7 to rotate clockwise or counterclockwise by a certain angle. The driving gear 7 moves the driving arm 6 through the cooperation with the third chute 71, and the driving arm 6 drives the rotating pin 3 to slide in the first chute 11 and the guiding chute 21. When the rotating pin 3 slides to one end of the first sub-chute 111 and the guiding chute 21 away from the second sub-chute 112, the child lock mechanism 100 is in the unlocked state; when the rotating pin 3 slides to one end of the second sub-chute 112 and the guiding chute 21 away from the first sub-chute 111, the child lock mechanism 100 is in the locked state.

[0053] Further, as Figure 7 and Figure 8 shown, the driving arm 6 includes a driving body 61, a positioning post 62, and at least one limiting protrusion 63. The driving body 61 is formed with a second chute 611. The positioning post 62 is provided on a side of the driving body 61 adjacent to the driving gear 7, and the positioning post 62 is slidably engaged with the third chute 71. The limiting protrusion 63 is provided on a side of the driving body 61 adjacent to the driving gear 7, and the limiting protrusion 63 and the positioning post 62 are spaced apart along the length direction of the driving body 61 (for example, Figure 7 the front-back direction in Figure 7 ). The second chute 611 is provided on one side in the thickness direction of the driving body 61 (for example, the up-down direction in Figure 7 ), and the second chute 611 faces the swing arm 1 to facilitate the rotating pin 3 to pass through the first chute 11 and the second chute 611. The positioning post 62 and the limiting protrusion 63 are provided on the other side in the thickness direction of the driving body 61 to prevent the positioning post 62 and the limiting protrusion 63 from interfering with the sliding engagement of the rotating pin 3 in the second chute 611.

[0054] Along the length direction of the driving body 61, a positioning post 62 and two limiting protrusions 63 are provided on the driving body 61. The positioning post 62 cooperates with the third chute 71 on the driving gear 7 to transmit the acting force on the driving gear 7 to the driving arm 6. During the rotation of the driving arm 6, the limiting protrusion 63 can abut against the driving arm 6 in the circumferential direction to prevent the driving arm 6 from rotating excessively, which is beneficial to restricting the movement of the driving arm 6 to improve the running stability of the driving arm 6. At the same time, the limiting protrusion 63 also has a certain strengthening effect on the structure of the driving body 61 to extend the service life of the driving body 61.

[0055] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 , the rotating pin 3 includes a first rotating portion 31, a second rotating portion 32 and a third rotating portion 33 connected axially. The first rotating portion 31 cooperates with the first chute 11, the second rotating portion 32 is arranged between the rocker arm 1 and the connecting arm 2, and the third rotating portion 33 cooperates with the guiding groove 21. With such a setting, it is beneficial for both axial sides of the second rotating portion 32 to contact the rocker arm 1 and the connecting arm 2 respectively, so as to improve the stability of the interval between at least part of the rocker arm 1 and the connecting arm 2, prevent the rocker arm 1 and the connecting arm 2 from tilting during use, and at the same time improve the stability of the rotating pin 3, thereby improving the stability and smoothness of the switching between the unlocking state and the locking state of the child lock mechanism 100.

[0056] Wherein, the cross-sectional area of the second rotating portion 32 is larger than the cross-sectional area of the first rotating portion 31, and / or the cross-sectional area of the second rotating portion 32 is larger than the cross-sectional area of the third rotating portion 33. Thus, it can prevent the rotating pin 3 from moving axially towards the first rotating portion 31 and / or the second rotating portion 32 excessively, which is beneficial to improving the setting stability and reliability of the rotating pin 3 between the rocker arm 1 and the connecting arm 2.

[0057] Further, the height of the second rotating portion 32 in the axial direction of the rotating pin 3 is less than or equal to the minimum distance between the rocker arm 1 and the connecting arm 2. When the height of the second rotating portion 32 in the axial direction of the rotating pin 3 is greater than the minimum distance between the rocker arm 1 and the connecting arm 2, the second rotating portion 32 abuts against the rocker arm 1 and the connecting arm 2 excessively, thereby increasing the resistance when the rotating pin 3 rotates, reducing the use experience of the child lock mechanism 100, and at the same time easily increasing the volume of the child lock mechanism 100 and reducing the applicability of the child lock mechanism 100. Therefore, by setting the height of the second rotating portion 32 in the axial direction of the rotating pin 3 to be less than or equal to the minimum distance between the rocker arm 1 and the connecting arm 2, it is beneficial to improve the rotation smoothness of the rotating pin 3 to enhance the user's use experience of the child lock mechanism 100.

[0058] According to some embodiments of the present invention, referring to Figures 1 - 3, a first connection hole 17 is formed on the first connection section 13, and a second connection hole 22 is correspondingly formed on the connection arm 2. The first connection hole 17 and the second connection hole 22 correspond to each other, and a rotating member is inserted into the first connection hole 17 and the second connection hole 22 to rotatably connect the rocker arm 1 and the connection arm 2. The first connection hole 17 is formed on the first connection section 13, reducing the distance between the first connection section 13 and the connection arm 2, which is beneficial to increasing the connection stability between the rocker arm 1 and the connection arm 2, realizing the coaxial rotational connection of the rocker arm 1 and the connection arm 2, and increasing the stability of the relative rotation between the rocker arm 1 and the connection arm 2.

[0059] Optionally, the convex rib can also be arranged along the circumferential direction of the second connection hole 22.

[0060] Optionally, a spacer is provided on the rotating member, and the spacer is located between the rocker arm 1 and the connection arm 2 to space at least part of the rocker arm 1 and the connection arm 2.

[0061] According to the child lock mechanism 100 of the embodiment of the present invention, the child lock mechanism 100 has the following working modes:

[0062] As Figure 9 shown, when the child lock mechanism 100 is in the unlocked state, the driving member 8 drives the driving gear 7 to rotate, so that the driving arm 6 moves. The driving arm 6 transmits the acting force to the rotating pin 3, and the rotating pin 3 slides to one end of the first sub-slot 111 and the guiding slot 21 away from the second sub-slot 112. The rocker arm 1 and the connection arm 2 are combined and can rotate together, and thus do not affect the normal opening and closing of the vehicle door.

[0063] As Figure 10 shown, when the child lock mechanism 100 is in the locked state, the rotating pin 3 slides to one end of the second sub-slot 112 and the guiding slot 21 away from the first sub-slot 111. The rocker arm 1 and the connection arm 2 are separated, so that only the rocker arm 1 can rotate idly through the door handle, and the connection arm 2 will not be driven to rotate. Therefore, it effectively avoids the danger of the vehicle door being opened due to a child accidentally pulling the door handle while riding in the vehicle.

[0064] The vehicle door assembly according to the second aspect embodiment of the present invention includes the child lock mechanism 100 according to the first aspect embodiment of the present invention above.

[0065] According to the vehicle door assembly (not shown in the figure) of the embodiment of the present invention, by adopting the above-mentioned child lock mechanism 100, it is beneficial to improve the applicability of the vehicle door assembly and extend the service life of the vehicle door assembly.

[0066] The vehicle (not shown in the figure) according to the third aspect embodiment of the present invention includes the child lock mechanism 100 according to the first aspect embodiment of the present invention above, or the vehicle door assembly according to the second aspect embodiment of the present invention above.
