Description

Technical Field

[0001] This utility model relates to the field of automotive locks, and more specifically, to a super lock mechanism. Background Technology

[0002] With the development and demands of the automotive market, automotive opening and closing systems not only need to be diversified, electric, and independent, but also need to retain the mechanical features of traditional side door locks. Doors need both an electric unlocking function and a traditional key backup, each independent and non-conflicting. The electric and mechanical unlocking functions control outward opening; similarly, inward opening requires a safety lock to ensure internal security. An independent internal superlock motor and transmission mechanism ensure that the internal safety features meet requirements. Externally, while retaining a mechanical backup key for mechanical unlocking, it also possesses a superlock function that can unlock both the internal and external safety locks at once, thus preventing situations where the internal and external safety locks cannot be unlocked when the vehicle is powered down or without power.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] Example

[0032] Reference Figures 1-8 A superlock mechanism includes a housing, wherein the housing is a mounting carrier for the superlock mechanism.

[0033] A motor 101 is fixedly mounted on the housing, and a worm gear 102 is fixedly mounted on the rotor of the motor 101.

[0034] A worm gear 103 is provided on the housing, which is connected to the housing and rotates around the first axis (a1 in the figure), forming a worm gear transmission structure with the worm 102.

[0035] A torsion spring 104 is installed on the housing. One end of the spring is fixed to the worm gear 103, and the other end is fixed to the housing. By setting an appropriate eccentric angle, the worm gear 103 is stably positioned between two extreme angles, providing a tactile feedback. The use of the torsion spring 104 to provide this tactile feedback is a well-known technology in the door lock industry and will not be elaborated upon here.

[0036] The housing is also equipped with a lever 75, which is rotatably connected to the housing about a second axis (a2 in the figure). The second axis is parallel to the first axis.

[0037] The housing is equipped with a pawl and a pawl release lever, both of which rotate together around a third axis (a3 in the figure) perpendicular to the second axis a2. When the pawl rotates to a set angle, it overcomes the torque of the pawl spring (not shown in the figure), disengaging from the bolt 11 and allowing the bolt 11 to rotate freely, thus unlocking the door. The cooperation between the pawl and the bolt 11 is well-known technology in the field of door locks and will not be elaborated upon here.

[0038] The lever 75 has a fourth axis (a4 in the figure), and a coupling rod 95 is mounted on the fourth axis a4. The coupling rod 95 is connected to the lever 75 by rotating around the fourth axis a4. The fourth axis a4 is parallel to the second axis a2.

[0039] An internal opening lever 91 is provided on the housing, and the internal opening lever 91 is mounted on the housing in a manner that allows rotation about a second axis a2. As a result, the lever 75 and the internal opening lever 91 can rotate independently about the second axis a2. A connecting hole 91a is provided on the internal opening lever 91, which engages with the pull cable 195 on the outside of the door lock. When an external force pulls the pull cable 195, the internal opening lever 91 rotates about the second axis a2, serving as a mechanical interface for operating the door lock. In particular, it serves as a mechanical interface for opening the interior of the vehicle.

[0040] The coupling rod 95 is provided with an actuating protrusion 95c, which is coupled to the internal opening lever protrusion 91c on the internal opening rod 91. When the rotation position of the coupling rod 95 couples the actuating protrusion 95c and the internal opening lever protrusion 91c, the pulling of the internal opening lever 91 will drive the coupling rod 95, and further drive the coupling rod 95 to rotate together, as shown. Figure 2 This causes the aforementioned mechanism to disengage the latch 11, a process that constitutes the internal opening function of the door lock. When the rotational position of the coupling rod 95 decouples the actuating protrusion 95c and the internal opening lever protrusion 91c, as... Figure 3 As shown, pulling the internal opening lever 91 causes the coupling rod 95 to rotate together. This prevents the latch 11 from being released. The above process constitutes the internal locking function of the door lock, meaning the door lock cannot be opened from the inside. Depending on the specific purpose, this can be a child lock function or a super lock function.

[0041] The coupling rod 95 is provided with an actuating protrusion 95b, which engages with the worm wheel protrusion 103b provided on the worm wheel 103. The motor 101 drives the worm wheel 103 to rotate, changing the position of the worm wheel protrusion 103b. When the worm wheel protrusion 103b pushes the actuating protrusion 95b to the aforementioned decoupling position, as... Figure 5The electric mechanism enables the aforementioned child lock or super lock functions. When the worm gear protrusion 103b no longer pushes the actuation protrusion 95b and reaches the aforementioned coupling position, as... Figure 4 The electric version achieves the aforementioned child lock or super lock unlocking functions.

[0042] The coupling rod (95) actuates the lever (75) to rotate.

[0043] In some embodiments, a contact switch (S4 in the figure) is provided on the housing. A cam 103c is provided on the outer wall of the worm gear 103. When the rotational position of the worm gear 103 is at... Figure 5 When the cam 103c is in the counterclockwise position, it does not contact the contact switch S4; when the worm gear 103 is in the clockwise position shown in Figure 4, the cam 103c presses the contact switch, changes its electrical signal, and serves as a signal feedback function for the child lock or super lock function.

[0044] In some embodiments, a key lever 69 is provided that can rotate about a fifth axis (a5 in the figure), which is perpendicular to the second axis a2. One end of the key lever 69 has a key lever protrusion 69d that can engage with an actuating protrusion 95c. As a result, the key lever 69 can push the coupling rod 95 to rotate about a fourth axis a4 at a specific rotation angle, such as... Figure 6 , Figure 7 , Figure 8 The sequence of actions causes the superlock mechanism to transition from the decoupled state to the coupled state. As a result, on the one hand, the internal opening lever 91 can operate the door lock to unlock; on the other hand, the rotation of the coupling lever 95 actuates the actuation protrusion 95b, which pushes the worm gear protrusion 103b, which in turn drives the worm gear 102 and the motor 101 to rotate, thus resetting the motor. In a typical application of automotive door locks, this is the function of unlocking the superlock with a mechanical key.

[0045] Finally, in some embodiments, a pull rod 65 is provided inside the housing, sliding along its length. A drive worm gear 83 rotatable about a sixth axis (a6 in the figure) is also provided. An external safety structure (not shown in the figure) is provided inside the housing, which, when the pull rod 65 is in... Figure 6 When the sliding position shown is to the left, it is in the upper outer safety state. When the lever 65 is in the position shown... Figure 8 When the sliding position is to the right, the external safety is disengaged. Simultaneously, the key lever 69, while pushing the internal safety from the disengaged state to the coupled state, also pushes the pull rod 65 from the sliding position left to the sliding position right, synchronously disengaging the external safety. This completes another action of unlocking the superlock with the mechanical key.

[0046] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
