[0018] The following detailed description provides various different embodiments or examples for implementing the present application. Of course, these are merely examples and are not intended to be limiting. Also, like reference numerals are used to designate like parts throughout the various examples and figures. These are used for a simpler and clearer description of the present application and do not represent a particular relationship between the various examples and / or structures being discussed.

[0019] The following description of the drawings and detailed description further describe the present application: as shown in Figures 1-6 A clutch transmission structure of a lock gearbox, comprising a box body 1 and a motor 2, a variable speed transmission gear set 3, a clutch gear set 4 and a power output gear 5 arranged in the box body 1, the output shaft of the motor 2 is in transmission connection with the variable speed transmission gear set 3, the clutch gear set 4 is movably arranged and can be in transmission connection with the variable speed transmission gear set 3 and can be in connection or disconnection with the power output gear 5.

[0020] In the present application, by arranging the variable speed transmission gear set 3, the clutch gear set 4 and the power output gear 5, when the lock motor 2 is normally unlocked, the clutch gear set 4 is in transmission connection with the power output gear 5, and finally the power output gear 5 is in transmission with the lock tongue assembly in the lock to achieve unlocking or locking, and when the motor 2 is not powered, the clutch gear set 4 is disconnected from the power output gear 5, so that the lock tongue assembly can be directly driven by the key manually to unlock or lock, thereby simplifying the structure of the key manual unlocking.

[0021] Further, a notch 51 is arranged on one side of the box body 1, and the power output gear 5 is arranged in the notch 51.

[0022] Referring to Figures 2-5 As shown, the clutch gear set 4 comprises a vertical shaft 21 arranged in the box body 1, a clutch swing plate 22 and a main gear 23 are sleeved on the vertical shaft 21, the main gear 23 is in transmission connection with the variable speed transmission gear set 3, a first clutch gear 24 and a second clutch gear 25 are arranged on the clutch swing plate 22, the first clutch gear 24 and the second clutch gear 25 are arranged on the left and right sides of the main gear 23 and can be engaged with the main gear 23, when the clutch swing plate 22 swings around the vertical shaft 21, the first clutch gear 24 or the second clutch gear 25 can be engaged with the power output gear 5 or the first clutch gear 24 and the second clutch gear 25 can be simultaneously disengaged from the power output gear 5.

[0023] It should be noted that when the motor 2 works to drive the variable speed transmission gear set 3 to engage with the main gear 23, due to the inertia caused by rotation, the first clutch gear 24 or the second clutch gear 25 can be kept in engagement with the main gear 23, as Figure 3As shown, when the main gear 23 rotates counterclockwise, it meshes with the first clutch gear 24 and generates inertia, causing the first clutch gear 24 and the clutch swing plate 22 to rotate counterclockwise, thereby keeping the first clutch gear 24 engaged with the power output gear 5; similarly, as Figure 4 As shown, when the main gear 23 rotates clockwise, the clutch sway plate 22 rotates clockwise, thereby keeping the second clutch gear 25 engaged with the main gear 23; while when the main gear 23 is not powered, the clutch sway plate 22 can drive the first clutch gear 24 and the second clutch gear 25 to swing, so that the first clutch gear 24 and the second clutch gear 25 are simultaneously disengaged from the main gear 23 (e.g., Figure 5 (As shown).

[0024] Furthermore, in order to facilitate the oscillation of the clutch swing plate 22, a clutch lever 31 is provided on the clutch swing plate 22.

[0025] See Figure 2 , 6 As shown, the variable speed transmission gear set 3 includes a first bevel gear 41 mounted on the output shaft of the motor 2, a second bevel gear 42 that meshes with the first bevel gear 41 mounted inside the housing 1, a transmission gear 43 mounted at the lower end of the second bevel gear 42, and multiple double-layer reduction gears 44 sequentially connected between the transmission gear 43 and the main gear 23; thus, by setting multiple double-layer reduction gears 44, high-speed, low-torque power can be converted into low-speed, high-torque power, thereby meeting the unlocking requirements.

[0026] Of course, there are many combinations of transmission methods for the gear set 3 of the speed transmission. For example, it can be transmitted by a worm gear, that is, a worm is provided on the output shaft of the motor 2, the worm gear cooperates with the worm, and the worm gear cooperates with the double-layer reduction gear 44 to transmit power, and finally realize the rotation of the main gear 23.

[0027] In this utility model, the box body 1 includes a bottom shell 61 and a cover shell 62, which are connected and fixed by a number of screws.
