Problems solved by technology

Their common defects are: first, it is necessary to regularly apply external force to the weight or spring to ensure that it does not stop working, and it is cumbersome to use and operate; The shortcoming of the small pendulum, because if the pendulum is enlarged or the design of the pendulum is enlarged, it will inevitably lead to the problem that the weight is too heavy or the clockwork mechanism is too large. For places that require a large pendulum, the current pendulum clock cannot meet the needs of users. need
Third, the driving mechanism drives the needle shaft and the pendulum to work through a complex transmission wheel train. The structure is complex, the failure rate is high, and maintenance and repair are inconvenient.

Embodiment 1

[0014] As shown in FIG. 1 , this embodiment includes a pendulum 1 , a pendulum mechanism 2 for driving the pendulum 1 to swing, and an escapement mechanism 4 for driving the pendulum mechanism 2 to work. Also be provided with motor 6, its output shaft is connected with worm screw 7, and the worm wheel 5 that is connected with this worm screw is connected with the escape wheel of escapement mechanism.

[0015] The upper end of the swing rod mechanism 2 is fixedly connected with the outer end of the swing rod drive shaft 3 , and the inner end of the swing rod drive shaft 3 is connected with the pallet fork of the escapement mechanism 4 .

[0016] Wherein the worm wheel 5 is coaxially connected with the escape wheel of the escapement mechanism 4 .

Embodiment 2

[0018] As shown in FIG. 2 , on the basis of the first embodiment, a gear transmission mechanism 8 is added, the worm gear 5 is coaxially connected with the driving gear therein, and the driven gear is coaxially connected with the escape wheel of the escapement mechanism 4 .

Embodiment 3

[0020] The motor 6, the worm 7, the worm wheel 5 and the escapement mechanism 4 are fixed in the casing to form an independent pendulum drive motor, which is directly connected with the pendulum drive shaft 3.

Abstract

This invention relates to improved pendulum drive device, which comprises pendulum, pendulum bar structure to drive the swing and work detent structure to drive the bar structure, motor with output axis connected to whirl bar, wherein, the whirl wheel matches with whirl bar connected to the detent wheel through spring parts; This invention can be made into large intelligent pendulum with diameter more than 100CM.

Description

technical field [0001] The invention relates to a pendulum driving device of a pendulum clock, in particular to a pendulum driving device with an improved structure. Background technique [0002] The driving mechanism of the existing pendulum clock generally adopts two modes of driving the sprocket wheel by the weight or driving the gear by the spring. Their common defects are: first, it is necessary to regularly apply external force to the weight or spring to ensure that it does not stop working, and it is cumbersome to use and operate; The shortcoming of the small pendulum, because if the pendulum is enlarged or the design of the pendulum is enlarged, it will inevitably lead to the problem that the weight is too heavy or the clockwork mechanism is too large. For places that require a large pendulum, the current pendulum clock cannot meet the needs of users. need. Third, the driving mechanism drives the needle shaft and the pendulum to work through a complex transmission ...
