A type of oblique tongue linkage mechanism

Abstract

This application discloses a latch linkage mechanism, including a mounting cavity disposed within a panel. A latch assembly and a driving device are disposed within the mounting cavity. The panel has an opening for the latch assembly to extend. The latch assembly has a limiting groove, and a toggle member is movably fitted onto the limiting groove. The toggle member is connected to the driving device. Under the action of the driving device, the toggle member rotates within the limiting groove to push the latch assembly back into the mounting cavity or extend out of the opening. Compared to the prior art, this application utilizes the limiting fit between the toggle member and the latch assembly to replace the gear and gear plate fit in the prior art, thereby effectively reducing noise generation.

Description

Technical Field

[0001] This utility model particularly relates to a slanted tongue linkage mechanism. Background Technology

[0002] Existing smart locks include a panel mounted on the door, with a mounting cavity inside the panel. An opening communicating with the mounting cavity is located on the side of the panel. A linkage mechanism is installed within the mounting cavity, and this mechanism includes a latch. Under external force, the linkage mechanism moves the latch, causing it to retract into the mounting cavity or extend out of the opening. Existing linkage mechanisms exhibit significant noise when engaging the latch, for the following reasons:

[0003] The current linkage mechanism includes a geared disc housed within the mounting cavity, a rack meshing on the geared disc, a transmission rod connected to the rack, and a pull rod on the slant. One end of the transmission rod is connected to the pull rod. The geared disc rotates under external force, thereby driving the rack to move. During the rack's movement, the transmission rod, in conjunction with the pull rod, drives the slant to move. Analysis shows that after repeated use, gears may experience root tearing, tip wear, or insufficient manufacturing precision in the geared disc and rack, which can also lead to noise issues during operation.

[0028] A latch linkage mechanism includes a mounting cavity 2 disposed in a panel 1, a latch assembly and a driving device 3 disposed in the mounting cavity 2, an opening 4 for the latch assembly to extend out of the panel 1, a limiting groove 5 disposed on the latch assembly, a toggle member movably fitted on the limiting groove 5, the toggle member being connected to the driving device 3, the toggle member rotating within the limiting groove 5 under the action of the driving device 3 to push the latch assembly to retract into the mounting cavity 2 or extend out of the opening 4.

[0029] Furthermore, the drive device 3 is a planetary motor.

[0030] Furthermore, the locking tongue assembly includes a slanted tongue 61, a pull rod 62 is provided on the slanted tongue 61, the limiting groove 5 is provided on the pull rod 62, and the pull rod 62 is movably disposed in the mounting cavity 2.

[0031] Furthermore, the pull rod 62 has an elastic element 7 connected to the end away from the tongue 61, and the elastic element 7 is connected to the panel 1.

[0032] Furthermore, the elastic element 7 is a spring.

[0033] Furthermore, the actuating element includes a mounting shell 81 connected to the driving device 3. The mounting shell 81 has a first side portion 811 and a second side portion 812 defined on it. A toggle block 82 is provided on the second side portion 812. A push portion 621 is provided on the pull rod 62. When the push portion 621 is located on the first side portion 811, the oblique tongue 61 extends out of the opening 4. When the mounting shell 81 rotates in conjunction with the toggle block 82 to push the push portion 621 to move away from the oblique tongue 61, the oblique tongue 61 retracts into the mounting cavity 2.

[0034] Furthermore, the toggle block 82 has a straight-line structure.

[0035] Furthermore, the limiting groove 5 has an L-shaped structure.

[0036] Furthermore, the mounting cavity 2 is provided with a mounting base 9 for mounting the planetary motor.

[0037] The working principle of this utility model is as follows:

[0038] like Figure 2 As shown, to better illustrate the design concept of this application, the mounting housing 81 is defined to have a first side 811 and a second side 812, and a toggle block 82 is provided on the second side 812, as... Figure 2 As shown, when locked, the oblique tongue 61 is in a state of extending out of the mounting cavity 2, by... Figure 1 It can be seen that at this time, the pushing part 621 on the pull rod 62 is located on the first side part 811 of the mounting shell 81. When unlocking is required, the drive device 3 is activated, and the drive device 3 drives the mounting shell 81 to rotate. The mounting shell 81 drives the actuating block 82 to rotate within the limiting groove 5. When the actuating block 82 rotates to the pushing part 621, the actuating block 82 will push the pushing part 621, causing the pushing part 621 to move in conjunction with the pull rod 62, ultimately causing the tongue 61 to retract into the mounting cavity 2. Figure 4 As shown. In Embodiment 1, the drive device 3 can be implemented using a planetary motor. Compared with the prior art, this application uses the limiting cooperation of the toggle member and the locking tongue assembly to replace the gear and gear plate cooperation in the prior art, thereby effectively reducing noise generation.

[0039] Regarding the cooperation between the slanted tongue 61 and the actuating component, a specific implementation method could be to provide a pull rod 62 on the slanted tongue 61, a limit groove 5 on the pull rod 62, and a pushing part 621 on the pull rod 62, such as... Figure 1As shown, when the oblique tongue 61 extends out of the mounting cavity 2, the mounting shell 81 drives the actuating block 82 to rotate until one end moves out of the limiting groove 5, and the length direction of the actuating block 82 is perpendicular to the length direction of the pull rod 62. The pushing part 621 on the pull rod 62 is located on the first side part 811 of the mounting shell 81. When the oblique tongue 61 is retracted into the mounting cavity 2, the mounting shell 81 drives the actuating block 82 to rotate, causing the actuating block 82 to push the pushing part 621 to move away from the oblique tongue 61. As shown in the figure, the actuating block 82 is completely located in the limiting groove 5 at this time.

[0040] Based on the above technical solution, this application further provides an elastic element 7 on the pull rod 62. One end of the elastic element 7 is fixed inside the mounting cavity 2. As in embodiment 1, the elastic element 7 can be implemented using a spring. The spring is provided to buffer the buffering force exerted on the door body by the tongue 61 extending out of the panel 1, preventing damage to the components.

[0041] Regarding the installation method of the planetary motor in the above-mentioned technical solution, a mounting base 9 for installing the planetary motor can be provided in the mounting cavity 2 of the panel 1.

[0042] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
