All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 7, in an embodiment of the present utility model, a dead bolt transmission mechanism for a motor home lock includes a lock body base 10, a dead bolt assembly 20 mounted on the lock body base 10, and a transmission assembly 30 mounted on the lock body base 10; the dead bolt assembly 20 and the transmission assembly 30 are movably connected to the lock body base 10, the dead bolt latch 21 is arranged at one end of the dead bolt assembly 20 extending into the lock body base 10, the transmission assembly 30 is provided with a transmission gear 31, the transmission gear 31 is in meshed connection with the dead bolt latch 21, and the transmission gear 31 drives the dead bolt latch 21 to drive the dead bolt assembly 20 to move.

Specifically, in order to improve the stability of the caravan lock, the dead bolt latch 21 is engaged with the toggle gear teeth 32, so that the stability of the dead bolt can be ensured during running. In addition, at least one dead bolt latch 21 may be provided, and for example, when the dead bolt assembly 20 is relatively long, a plurality of dead bolt latches 21 may be provided. Likewise, a plurality of toggle gear teeth 32 may be provided, and in general, the toggle gear teeth 32 need to be one more than the number of dead bolt latch teeth 21, because the toggle gear teeth 32 need to perform two operations of forward and backward movement on the dead bolt latch teeth 21, so as to achieve two effects of locking and unlocking.

As shown in fig. 5 and 6, the transmission gear 31 is provided with at least two stirring gear teeth 32, the stirring gear teeth 32 are in meshed connection with the dead bolt latch teeth 21, and the stirring gear teeth 32 drive the dead bolt latch teeth 21 to drive the dead bolt assembly 20 to move. Specifically, the engagement connection formed by the poking gear teeth 32 and the dead bolt latch teeth 21 is loose connection, namely, a certain gap can exist between the poking gear teeth 32 and the dead bolt latch teeth 21, and on the basis that the poking gear teeth 32 can drive the dead bolt latch teeth 21, the dead bolt assembly 20 can be prevented from crashing the dead bolt latch teeth 21 or poking the gear teeth 32 in the running shake of the motor home by setting a certain gap. In addition, the sizes of the toggle gear teeth 32 and the dead bolt latch teeth 21 can be set to be relatively larger, so that the structural strength of the dead bolt latch teeth is increased, and the reliability of the transmission mechanism is further improved.

As shown in fig. 4, the transmission assembly 30 is provided with a rotation shaft body 33, the rotation shaft body 33 is movably connected to the lock body base 10, the transmission gear 31 is coaxially and fixedly connected with the rotation shaft body 33, and the transmission gear 31 synchronously rotates along with the rotation shaft body 33. Specifically, the transmission gear 31 and the rotating shaft body 33 may be integrally formed as one component, or may be two components assembled together to form an integral component.

Specifically, the manual handle 12 can drive the rotation shaft 33 to rotate, so as to drive the transmission gear 31 to rotate synchronously, so that the toggle gear teeth 32 form toggle pushing force on the dead bolt latch 21, and the dead bolt assembly 20 moves a certain distance, thereby realizing the locking or unlocking operation.

As shown in fig. 2, 3 and 7, the dead bolt transmission mechanism further comprises a lock cylinder assembly 11, a central axis of the lock cylinder assembly 11 coincides with a central axis of the rotating shaft body 33, the lock cylinder assembly 11 and the rotating shaft body 33 form a buckling connection, and the lock cylinder assembly 11 drives the rotating shaft body 33 to rotate. Specifically, the lock core assembly 11 may be directly sleeved on the rotating shaft body 33, or connected by a buckle of a matching fixture block and a buckling block, so long as the lock core assembly 11 can be opened by using a key, the key can be turned, and the lock core assembly 11 can be synchronously turned, thereby driving the rotating shaft body 33 to synchronously rotate, and unlocking or locking operation can be performed.

As shown in fig. 3 and 4, the dead bolt transmission mechanism further comprises an electric component 40, the electric component 40 is fixedly connected to the lock body base 10, and the electric component 40 is in meshed connection with the transmission component 30, so that the electric component 40 drives the transmission component 30 to rotate to drive the dead bolt latch 21 to move. The electric assembly 40 is provided with a gear motor 41 and a driving gear, the gear motor 41 is fixedly connected to the lock body base 10, the driving gear is fixedly connected to an output shaft of the gear motor 41, and the gear motor 41 drives the driving gear to rotate. Specifically, the gear motor 41 may be a combination of a single motor and a single speed reducer, or may be a single gear motor 41. It is preferable to use the single four-stage gear motor 41 because the single gear motor 41 has a compact internal structure, and the reliability is higher and the stability of the transmission mechanism can be improved through the quality inspection cooperation of the factory. In addition, it has been found through experiments that the use of the four-stage reduction motor 41 is most suitable, and the reduction of the motor rotation speed and the improvement of the motor torque meet the use requirements. When the manual rotary handle 12 is rotated or the key is used for rotating the lock cylinder assembly 11, the driving gear is driven by the rotating shaft body 33, so that the rotating moment for driving the gear motor 41 is just suitable, and the situation that the moment is too large and the rotation cannot be realized can be avoided.

The central angle of the sector gear 35 cannot be too small, which is not beneficial to the connection of the driving gear; nor too large to use, but rather waste material.

When the lock is used, the dead bolt transmission mechanism is arranged on the car lock and is arranged at the car door position of the car, so that the locking effect on the car door is realized. The dead bolt transmission mechanism can be used for locking or unlocking by using the manual rotary handle 12 in a motor home, and can also be used for operating the lock cylinder assembly 11 by using a key outside the motor home, so that the locking or unlocking operation is realized. In addition, the motor home lock can be locked or unlocked through the electric assembly 40. It will be appreciated that the power assembly 40 herein may also be used in conjunction with other components (not shown) to effect remote locking or unlocking operations.

In addition, the rotating shaft body 33 can be movably connected to the lock body base 10 in a sleeve manner, preferably, the rotating shaft body 33 is movably connected to the lock body base 10 through a bearing, and the bearing can enable the rotating shaft body 33 to be connected to the lock body base 10 more reliably and also can rotate more stably.
