[0017] Figure 1 is an exploded view of components of an electric lacing drive according to some example embodiments. Figure 1An electric shoelace lacing transmission device shown includes a reduction motor assembly 10 and a transmission assembly 20.

The reduction motor 10 provides power and rotational speed for the electric shoelace lacing transmission device; the transmission assembly transmits power and rotational speed. The reduction motor assembly 10 and the transmission assembly 20 are mechanically mated to transmit the power and rotational speed output by the reduction motor 10 to the transmission assembly 20. The transmission assembly 20 transmits power and rotational speed and completes lacing and unlacing the shoelace within a specific time, corresponding to tightening and loosening the shoelace.

[0018] Figure 2 and Figure 3 is a top view of an electric shoelace lacing transmission device according to some exemplary embodiments, Figure 2 and Figure 3 as shown, it includes a motor 110, a vertical reducer 120, a driving member 210, a driven member 220, a winding ring 230, and a shoelace 240. Figure 2 and Figure 3 show the main components of the electric shoelace lacing transmission device. An electric shoelace lacing transmission device starts with the motor 110 being powered on and the motor shaft rotating, driving the internal gears of the vertical reduction motor 120 to mesh and its output shaft to rotate, driving the driving member 210 to rotate, thereby driving the driven member 220 to rotate, and further driving the winding ring 230 to rotate. The shaft of the motor 220 rotates clockwise and counterclockwise, thus driving the winding ring to rotate clockwise and counterclockwise; thereby achieving the purpose of tightening and loosening the shoelace;

[0019] In Figure 2 the example, the driving member 210 is a worm structure, and the driven member 220 is a turbine structure. The power and rotational speed for lacing the shoelace are transmitted through gear transmission. In Figure 3 the instance, the driving member 210A is a spur gear or a bevel gear, and the corresponding driven member 220A is a crown gear or a bevel gear. The power and rotational speed for lacing the shoelace are transmitted through gear transmission; Figure 2 and Figure 3 the shown structural principles are the same;

[0020] Figure 4 and Figure 5 are a top view and a front view of the lacing part of an electric shoelace lacing transmission device according to some exemplary embodiments. In the example of this figure, the winding ring 230 includes a winding groove 231 and a central hole 232, and the shoelace includes a right shoelace 241, a left shoelace 242, and a shoelace center knot 243; the shoelace center knot 243 is stuck in the central hole 232 of the winding ring 230 to ensure that the lengths of the shoelaces on both sides of the right shoelace 241 and the left shoelace 242 are the same during the process of winding and unwinding;

[0021] In the example of this figure, the shoelace 240 is placed in the middle winding groove 231 of the winding loop 230. When the winding loop 230 rotates clockwise, the right shoelace 241 winds around the upper winding groove 231, and the left shoelace 242 winds around the lower winding groove 231, so as to achieve the purpose of tightening the shoelace; when the winding loop 230 rotates counterclockwise, the right shoelace 241 and the left shoelace 242 are simultaneously untied from the winding groove 231 to achieve the purpose of loosening the shoelace.

[0022] Figure 6 It is a simplified view of the speed reducer of an electric shoelace lacing drive device according to some exemplary embodiments.

The gear 122 is installed on the motor shaft and rotates with the rotation of the motor shaft, and drives the gear 123 meshing with its teeth to rotate. The gear 123 drives the speed reducer output shaft 121 coaxial with it to rotate; the gear 122 and the gear 123 can be a worm and a worm wheel, and the worm wheel can be replaced by a helical gear; it can be a pair of bevel gears; it can be a spur gear and a crown gear, so as to drive the rotation of the entire system while keeping the motor shaft and the output shaft perpendicular.

[0023] Figure 7 It is a simplified view of the speed reducer of an electric shoelace lacing drive device according to some exemplary embodiments. In the example of this figure, the vertical speed reducer part can be formed by assembling two sets of meshing gears. The gear 122 is installed on the motor shaft and rotates with the rotation of the motor shaft, and drives the gear 123A meshing with its teeth to rotate. The gear 123A then drives the gear 124 meshing with its teeth to rotate. The gear 124 drives the speed reducer output shaft 121 coaxial with it to rotate; the gear 123A is composed of two coaxial gears, namely the gears 123A1 and 123A2. Among them, the gear 123A1 is assembled with the teeth of the gear 122, and the gear 123A2 is assembled with the teeth of the gear 124. One of the two sets of meshing gears can be a worm and a worm wheel, the worm wheel can be replaced by a helical gear, it can be a pair of bevel gears, it can be a spur gear and a crown gear; so as to drive the rotation of the entire system while keeping the motor shaft and the output shaft perpendicular.

[0024] Figure 8Is a simplified view of a speed reducer of an electric shoelace driving device according to some exemplary embodiments. In the example of this figure, the vertical speed reducer part can be formed by assembling multiple sets of meshing gears. The gear 122 is installed on the motor shaft and rotates with the rotation of the motor shaft, and drives the gear 123A meshing with its teeth to rotate. The gear 123A then drives the gear 124A meshing with its teeth to rotate. The gear 124A then drives the gear 125 meshing with its teeth to rotate. The gear 125 drives the output shaft 121 of the speed reducer coaxial with it to rotate; the gear 123A is composed of two coaxial gears, namely the gear 123A1 and 123A2, and the gear 124A is composed of two coaxial gears, namely the gear 124A1 and 124A2.

In the example of this figure, the vertical gearbox can be extended to multiple sets of tooth mating assemblies. The number of sets of gears selected mainly depends on the selection of output torque and speed in the usage scenario. At least one set of the multiple sets of meshing gears can be a worm and worm gear. The worm gear can be replaced by a helical gear, can be a pair of bevel gears, or can be a spur gear and a crown gear; so as to drive the rotation of the entire system while making the motor shaft and the output shaft perpendicular.
