The FIGURE illustrates an embodiment of a shoe 100. The shoe 100 can include a shoe upper 10, a sole 30, an actuator 40, a transducer 50, and a thermostat 70. The sole 30 can be mounted on a bottom of the shoe upper 10. The actuator 40 can be mounted on a side of the sole 30 adjacent to the shoe upper 10. The transducer 50 can be received in the sole 30. The thermostat 70 can be electrically coupled to the transducer 50. The actuator 40 can be configured to activate the transducer 50 to generate heat. The transducer 50 can be configured to convert kinetic energy generated by movement to thermal energy. The thermostat 70 can be configured to control the temperature of the shoe 100 at an approximate predetermined temperature.
The sole 30 can include a base 31 and a heel 32 which can be coupled to an end of the base 31. The heel 32 can define a chamber 324. The actuator 40 can cover an opening of the chamber 324 facing the shoe upper 10. The actuator 40 can be made of elastic material, thus, the actuator 40 can be capable of deforming and automatically restoring its initial shape after deformation. The actuator 40 can be made of heat conduction material and spread all over a side of the sole 30 adjacent to the shoe upper 10, which enables the actuator 40 to uniformly and quickly transfer the thermal energy generated by the transducer 50 to the shoe upper 10.
The transducer 50 can be received in the chamber 324, and can include a micro-motor 52, a link structure 54, a buffering assembly 55, a heater 56, and a heat-transfer tube 58.
The micro-motor 52 can be fixedly mounted on a bottom wall of the chamber 324, and can include a rotor (not shown). The link structure 54 can be positioned between the micro-motor 52 and the actuator 40. Thus, when the actuator 40 deforms or restores its deformation, the link structure 54 can be capable of moving the rotor of micro-motor 52 to generate electric energy. In the illustrated embodiment, the link structure 54 can include a first coupling rod 5422, a second coupling rod 5426 and a third coupling rod 5428 arranged in order. A first end portion of the first coupling rod 5422 can be coupled to the micro-motor 52. A first end portion of the second coupling rod 5426 can be pivoted to a second end portion of the first coupling rod 5422 away from the micro-motor 52. A first end portion of the third coupling rod 5428 can be pivoted to a second end portion of the second coupling rod 5426 away from the first coupling rod 5422.
The buffering assembly 55 can be positioned between the link structure 54 and the actuator 40, thereby enabling the link structure 54 to receive a uniform pressure. The buffering assembly 55 can include a supporting member 554 and at least one elastic member 554. The supporting member 554 can be substantially a rectangular plate. A side of the supporting member 554 adjacent to the link structure 54 can be fixedly mounted to a second end portion of the third coupling rod 5428 away from the second coupling rod 5426. Two opposite ends of the elastic member 556 can be fixed to a side of the supporting member 554 away from the link structure 54 and the actuator 40, respectively. In this exemplary embodiment, the buffering assembly 55 can include three elastic members 556 arranged spaced from each other.
The heater 56 can be electrically coupled to the micro-motor 52, and configured to convert the electric energy provided by the micro-motor 52 to thermal energy. The heater 56 can be at least one heating wire. Two opposite ends of the heat-transfer tube 58 can be coupled to the heater 56 and the actuator 40, respectively. The heat-transfer tube 58 can be configured to transfer the thermal energy from the heater 56 to the actuator 40.
The thermostat 70 can include a temperature sensor 72 and a temperature controller 74. In this exemplary embodiment, the temperature sensor 72 can be mounted on the actuator 40 and configured to detect a temperature of the shoe 100. The temperature controller 74 can be mounted on the heel 32 and configured to control the temperature of the shoe 100. The temperature controller 74 can be coupled to the temperature sensor 72. The temperature controller 74 can be electrically coupled to the micro-motor 52. The temperature controller 74 can further include a display panel 742 mounted on an outer sidewall of the heel 32 for displaying the temperature of the shoe 100. The display panel 742 can be a touch panel which can be employed to set a predetermined temperature by the user.
In assembly, the micro-motor 52 can be mounted in the heel 32. One end of the link structure 54 can be coupled to the micro-motor 52; the other end of link structure 54 away from the micro-motor 52 can be fixed to the supporting member 554. One end of the elastic member 556 can be mounted on the supporting member 554. The heater 56 can be electrically coupled to the micro-motor 52. The heat-transfer tube 58 can be coupled to the heater 56 and extend toward the shoe upper 10. The actuator 40 can be mounted on a top of the sole 30, and coupled to the elastic member 556 and the heat-transfer tube 58 by its portion adjacent to the heel 32. The temperature sensor 72 can be mounted on the actuator 40. The temperature controller 74 can be coupled to the temperature sensor 72 and electrically coupled to the micro-motor 52.
In use, a predetermined temperature can be set via the temperature controller 74. When a user presses and forces the actuator 40 in the course of walking or exercise, the actuator 40 can be deformed or restore its deformation which allows the elastic member 556 to compress and decompress repeatedly. Thus, the force generated during the movement can be transferred to the supporting member 554 uniformly which moves the supporting member 554 upward and downward to further rotate the link structure 54. Then, the rotating link structure 54 moves the rotor of the micro-motor 52 to generate electric energy. The heater 56 can convert the electric energy provided by the micro-motor 52 into thermal energy. The heat-transfer tube 58 can transfer the thermal energy from the heater 56 to the actuator 40. Then the actuator 40 can transfer the thermal energy into the shoe upper 10 to keep the foot of the user warm. When the temperature sensor 72 detects the temperature of the shoe 100 is higher than the predetermined temperature, the temperature controller 74 can be capable of stopping the micro-motor 52. Then the heater 56 stops working due to a lack of the electric energy, preventing the temperature of the shoe 100 from being too high. When the temperature sensor 72 detects the temperature of the shoe 100 is lower than the predetermined temperature, the temperature controller 74 can activate the micro-motor 52 to work again. Thus, the micro-motor 52 can provide electric energy for the heater 56 to generate heat again. As such, the temperature of the shoe 100 can be kept at an approximate predetermined temperature.
In at least one embodiment, the actuator 40 can only cover the opening of the chamber 324 facing the shoe upper 10. The actuator 40 can be made of non-elastic material as long as the actuator 40 can bend when an external force is applied on it and can restore from the deformation when the external force is removed. The link structure 54 can be directly coupled to the actuator 40 and then the buffering assembly 55 can be omitted. The sole 30 can be thick enough to receive the transducer 50 and then the heel 32 can be omitted. The heat generated by the heater 56 can be directly transferred to the actuator 40 and then the heat-transfer tube 58 can be omitted. The temperature sensor 72 can be located on shoe upper 10. The temperature controller 74 can be located on the shoe upper 10 or in the sole 30. The number of the elastic members 546 can be one, two or more than three. The shoe 100 can also include several buttons mounted on the shoe upper 10 or the sole 30 for setting parameters such as a predetermined temperature or so on.
