ENERGY HARVESTER ACTUATORFIELD

[0001] The present disclosure relates to the field of energy harvesters. More particularly, to energy harvester actuators.BACKGROUND

[0002] Energy harvesting devices can be used in different devices such as, for example, sensors and switches. Oftentimes, energy harvesting devices can be utilized in devices that are in remote locations where a permanent power supply is not available. In such situations, mechanical energy harvesters can be used instead of batteries that typically require recharging or replacement periodically. The energy produced by the energy harvesting device can be utilized for electronic communication with other components.BRIEF DESCRIPTION OF THE DRAWINGS

[0003] Some embodiments of the disclosure are herein described, by way of example only, with reference to the accompanying drawings. With specific reference now to the drawings in detail, it is stressed that the embodiments shown are by way of example and for purposes of illustrative discussion of embodiments of the disclosure. In this regard, the description taken with the drawings makes apparent to those skilled in the art how embodiments of the disclosure may be practiced.

[0010] The various embodiments of the present disclosure relate to an energy harvester or a system or device including an energy harvester of the present disclosure. The energyharvester can include an actuator. The device can include an actuator assembly mechanically coupled to the energy harvester, according to some embodiments. The actuator can include mechanical linkages configured to cause multiple actuations of the energy harvester due to an actuation such as, for example, by a user operating a switch device including the energy harvester. The energy harvester can be capable of producing increased energy as a function of the multiple actuations. The energy harvesters can also be capable of storing the electrical energy. The energy harvester can supply the electrical energy to one or more signal components to enable the device including the energy harvester to produce one or more signals, as will be further described herein. Accordingly, the energy harvester is capable of meeting increased energy needs of devices and providing longer functionality based on the actuation. In some embodiments, the movement of the actuator can be linear. In other embodiments, the movement of the actuator can be rotary.

[0011] The various embodiments of the energy harvester provide improvements over other known energy harvester switch devices including providing improved efficiency in operation by harvesting a greater amount of energy for a single mechanical actuation compared with other energy harvesters. Other known energy harvesters typically include a rocker or push switch that utilizes the principle of mechanical actuation to cause a single or double energy harvesting cycle by an energy harvester for each actuation of the switch. Accordingly, these other energy harvesters are generally limited in the amount of electrical energy they generate to power respective devices and typically for a limited functionality. Devices including the energy harvester of the present disclosure can be utilized with improved reliability over other energy harvester devices by triggering multiple actuations of the energy harvester and generating more electrical energy that can be harvested for powering the system or device for each actuation of the switch as a function of the operation of the actuator assembly. In other energy harvester devices, the limited amount of energy harvested in these devices can be exhausted in less time such as after a limited number of communication activation attempts. For example, other energy harvester devices can deplete the harvested energy with three activation messages over a 40 msec period.

[0012] Moreover, the increased use of Wi-Fi and other radio frequency (RF) devices in an environment of the device including the energy harvester can lead to increased interference or jamming caused by increased traffic from these other devices in the environment. For example, the increased use of Wi-Fi and other RF devices on vehicles, and the resulting increased signal traffic can jam or interfere with the wireless transmission of control signals by the device. The greater electrical power production and storage of the electrical power bythe devices including the energy harvester and by operation of the mechanical linkages of the actuator assembly of the present disclosure improves the reliability of transmission links of the device by enabling, for example, longer wireless transmission periods. In this regard, devices including the energy harvester of the present disclosure can be utilized with improved performance and reliability in challenging radio frequency (“RF”) environments where transmissions can easily be jammed by other transmissions in the vicinity of the device. The devices including the energy harvester of the present disclosure are capable of increased energy harvesting for each actuation of the device, thereby enabling the device to maintain an increased transmission duration and improving the probability of a successful message broadcast by the device.

[0013] Among those benefits and improvements that have been disclosed, other objects and advantages of this disclosure will become apparent from the following description taken in conjunction with the accompanying figures. Detailed embodiments of the present disclosure are disclosed herein; however, it is to be understood that the disclosed embodiments are merely illustrative of the disclosure that may be embodied in various forms.

[0030] The at least one recess 134 can include a shape having any of a plurality of profiles and dimensions including, but not limited to, concave shapes, arcuate shapes, angular shapes, orthogonal shapes, other profiles, or any combination thereof, such that the at least one recess 134 extends into the first body 122 of first activation member 120 at the first side 128 and the engagement portion 152 of second activation member 140 engaging (e.g., contacting) the surface of the first body 122 of first activation member 120 at the first side 128 can be displaced in an inward lateral direction relative the first activation member 120 by engaging the at least one recess 134 as the first activation member 120 moves between the first axial position and the second axial position along the first axis 180 so as to actuate the energy harvester 106. In some embodiments, the at least one recess 134 can have a concave shape that curves inward into the first body 122 of first activation member 120 at the first side 128. In other embodiments, the at least one recess 134 can have an orthogonal shape that forms a step that radially extends inward into the first body 122 of first activation member 120 at the first side 128 and towards a central longitudinal axis of first activation member 120.

[0031] According to some embodiments, the at least one recess 134 can include two recesses, three recesses, four recesses, or four or more recesses disposed at the first side 128 of first body 122 of first activation member 120. In some embodiments, the first body 122 of first activation member 120 can include at least two recesses such as recess 134 located at the first side 128, and each of the recesses 134 can be located adjacent the at least one protrusion 132 so as to enable the multiple actuations of the energy harvester 106, as will be further described herein. As shown in the non-limiting example of device 102 in FIG. 2, the first activation member 120 can include a first recess 134a and a second recess 134b, the first recess 134a disposed between first protrusion 132a and second protrusion 132b and thesecond recess 134b disposed between second protrusion 132b and the second end 126 of first activation member 120, in some embodiments.

[0032] According to some embodiments, the first body 122 of first activation member 120 can include a receptacle 136 arranged at the second end 126 of first activation member 120. The receptacle 136 can extend into the first body 122 towards the first end 124 of first activation member 120. In some embodiments, the receptacle 136 can be formed by a bore extending into the first body 122 of first activation member 120, the first body 122 at the second end 126 defining an opening of receptacle 136. The receptacle 136 can be defined by at least one inner side wall and a bottom surface. The receptacle 136 can include a size and dimensions configured to receive a first spring element 160.

[0033] The device 102 includes second activation member 140. Second activation member 140 includes a second body 142 arranged on a second axis 182 (which may be parallel or substantially parallel to first axis 180 when the first and second activation members 120, 140 are at rest). The second body 142 of second activation member 140 includes a first end 144, a second end 146 opposite the first end 144, a first side 148, and a second side 150 opposite the first side 148. The second body 142 of second activation member 140 includes an engagement portion 152 located at the first side 148 of second body 142 of second activation member 140, the engagement portion 152 protruding outward from the second body 142 of second activation member 140 in a radial direction relative second axis 182. In housing 104 of device 102, the second activation member 140 can be arranged adjacent to first activation member 120 such that the engagement portion 152 of second body 142 extends towards the first side 128 of first activation member 120, and the engagement portion 152 can engage a surface of the first side 128 of first body 122 of first activation member 120.

[0034] During the movement of the first activation member 120 between the first axial position and the second axial position, the engagement portion 152 engages the surface of the first body 122 of first activation member 120 at the first side 128 including engaging a portion of the surface including one or more engagement members. The engagement portion 152 of the second body 142 of second activation member 140 engaging the one or more engagement members on the surface of the first body 122 of first activation member 120 at the first side 128 causes movement of the second body 142 of second activation member 140 at the first end 144 between a first lateral position and a second lateral position. The one or more engagement members can include at least one protrusion 132, at least one recess 134, or both the at least one protrusion 132 and at least one recess 134, according to some embodiments.

[0035] In addition, the second body 142 of second activation member 140 translates the movement at the first end 144 of second body 142 to the second end 146 of second body 142, the second activation member 140 at the second end 146 being mechanically coupled to energy harvester 106. In this regard, the movement of first activation member 120 between the first axial position and the second axial position actuates movement of second activation member 140 between the first lateral position and the second lateral position as a function of the mechanical linkage between first activation member 120 and second activation member 140, and thereby actuates the energy harvester 106 as a function of the mechanical coupling between second activation member 140 and energy harvester 106.

[0036] According to some embodiments, the first body 122 of first activation member 120 includes a first longitudinal length and the second body 142 of second activation member 140 includes a second longitudinal length. In some embodiments, the second longitudinal length can be less than the first longitudinal length.

[0037] The device 102 includes a first spring element 160. First spring element 160 can be configured to apply a first spring force onto the first activation member 120 to return the first activation member 120 to the first axial position in response to the first activation member 120 being slidably moved to the second axial position from the first axial position by an actuation force applied to the first end 124 of first activation member 120. The first spring element 160 can include, but is not limited to, straight coil springs, barrel springs, concave springs, conical springs, variable rate springs, banana springs, torsion springs, volute springs, flat springs, gas springs, air springs, other types of springs, or any combination thereof.

[0038] First spring element 160 can be arranged between first activation member 120 and at least one sidewall of housing 104. First spring element 160 can be configured to apply the first spring force to the first activation member 120 to maintain the first activation member 120 in the first axial position. That is, the first activation member 120 slidably moving from the first axial position to the second axial position in response to an actuation force applied onto the first end 124 of first activation member 120 compresses first spring element 160, and the first spring force of first spring element 160 applied to the first activation member 120 can return the first activation member 120 from the second axial position to the first axial position in response to the actuation force being removed from the first end 124 of first activation member 120, the first activation member 120 slidably moving from the second axial position to the first axial position.

[0039] In some embodiments, first spring element 160 can apply the first spring force between the second end 126 of first body 122 of first activation member 120 and the at leastone sidewall of housing 104. In other embodiments, the first activation member 120 can include a receptacle 136 at the second end 126 of first body 122, and the first spring element 160 can extend between a bottom surface of receptacle 136 and the at least one sidewall of housing 104 and apply the first spring force of first spring element 160 between the bottom surface of receptacle 136 and the at least one sidewall of housing 104 in response to the actuation force that slidably moved the first activation member 120 from the first axial position to the second axial position being removed from the first end 124 of first body 122 of first activation member 120.

[0040] The first spring element 160 returning the first activation member 120 to the first axial position from the second axial position effectively doubles the number of actuations of energy harvester 106 that results from a single actuation of first activation member 120 as a function of the mechanical linkage between the first activation member 120 and the second activation member 140 as a result of the engagement portion 152 engaging a surface of the first activation member 120 at the first side 128 including the one or more engagement members.

[0041] In some embodiments, the at least one sidewall of housing 104 can include a first member 184 configured to retain a position of first spring element 160 relative the at least one sidewall of housing 104. In this regard, the first member 184 can be configured to retain the position of first spring element 160 between the at least one sidewall of housing 104 and the first activation member 120. In some embodiments, the first member 184 can be configured to retain the position of first spring element 160 between the at least one sidewall of housing 104 and in the receptacle 136 of first activation member 120.

[0042] The first member 184 can include a shape having any of a plurality of profiles and dimensions including, but not limited to, convex shapes, arcuate shapes, angular shapes, orthogonal shapes, other profiles, or any combination thereof, such that the first member 184 retains the position of the first spring element 160 between the at least one sidewall of housing 104 and the first activation member 120. In some embodiments, the first member 184 can have an orthogonal shape so as to form a step protruding from the at least one sidewall of housing 104.

The one or more engagement members can be sequentially arranged in an alternating order on the first body 122 of first activation member 120 at the first side 128. In some embodiments, the one or more engagement members can include at least one protrusion 132 or at least one recess 134. In other embodiments, the one or more engagement members can include at least one protrusion 132 and at least one recess 134. Referring to FIGS. 3 and 4, for example, the first activation member 120 includes one or more engagement members including first protrusion 132a, second protrusion 132b, first recess 134a, and second recess 134b located on first body 122 at the first side 128.

[0054] First activation member 120 can slidably move between first axial position 188 and second axial position 190. First activation member 120 can be located at first axial position 188 as a function of first spring element 160 applying the first spring force onto first activation member 120. An actuation force 192 can be applied to the first end 124 of first activation member 120, and the first activation member 120 can slidably move from first axial position 188 to second axial position 190 in response to the actuation force 192. Inaddition, removing the actuation force from the first activation member 120 can cause the first spring force of first spring element 160 to return the position of first activation member 120 to first axial position 188 by slidably moving the first body 122 from second axial position 190 to first axial position 188.

[0055] Second activation member 140 can engage the surface of first body 122 of first activation member 120 at the first side 128. Second activation member 140 can pivotably move laterally outward relative the first side 128 of first activation member 120 from first lateral position 194 to second lateral position 196 by the engagement portion 152 of second activation member 140 engaging the at least one protrusion 132. In addition, second activation member 140 can pivotably move laterally inward relative the first side 128 of first activation member 120 from second lateral position 196 to first lateral position 194 by the engagement portion 152 of second activation member 140 engaging the at least one recess 134.

[0056] In this regard, during movement of first body 122 of first activation member 120 between the first axial position 188 and the second axial position 190, the second body 142 of second activation member 140 is configured to translate movement from the first lateral position 194 to the second lateral position 196 at the first end 144 of second body 142 of second activation member 140 to the second end 146 of second body 142 of second activation member 140 to actuate energy harvester 106 a cycle for each of the at least one protrusion 132 in response to the engagement portion 152 engaging the at least one protrusion 132 of first activation member 120.

Accordingly, the mechanical linkage from the engagement portion 152 of second activation member 140 engaging the first body 122 of first activation member 120 at the first side 128 provides the multiple actuations of energy harvester 106 coupled to the second activation member 140 at the second end 146 in response to an actuation of the first activation member 120.

[0057] For example, referring to FIG. 3, the first activation member 120 moving from first axial position 188 to second axial position 190 actuates energy harvester 106 four cycles by the engagement portion 152 of second activation member 140 engaging second recess 134b,engaging second protrusion 132b, engaging first recess 134a, and engaging first protrusion 132a. For example, referring again to FIG. 3, the first activation member 120 moving from second axial position 190 to first axial position 188 actuates energy harvester 106 four cycles by the engagement portion 152 of second activation member 140 engaging first protrusion 132a, engaging first recess 134a, engaging second protrusion 132b, and engaging second recess 134b.

For example, a user can directly apply the actuation force to the first activation member 120 at the first end 124. In other embodiments, although not shown in the figures, device 102 can include another component in connected engagement with first activation member 120, and application of the actuation force onto the other component can be translated to the first activation member 120 at the first end 124 to cause the first activation member 120 to move between the first axial position 188 and the second axial position 190. The other component can include, for example, a button or button assembly for translating an actuation force onto the first activation member 120. In another example, the other component can include an actuator device for applying an actuation force onto the first activation member 120.

[0059] Referring to FIG. 4, the first activation member 120 is shown positioned between first axial position 188 and second axial position 190. Engagement portion 152 of second activation member 140 is shown engaging the at least one protrusion 132 at the surface of first body 122 of first activation member 120 at the first side 128. In addition, the second activation member 140 is shown in the second lateral position 196 and compressing second spring element 170. The second body 142 of second activation member 140 translates the positioning of the first end 144 of second body 142 in the first lateral position 194 to the second end 146 of second body 142 of second activation member 140, the second activation member 140 at the second end 146 being mechanically coupled to the energy harvester 106 to actuate the energy harvester 106 as the first activation member 120 pivotably moves between first lateral position 194 and second lateral position 196.

[0060] The first activation member 120 can include a third side 137 extending between first side 128 and second side 130 and a fourth side 138 extending between first side 128 and second side 130 opposite third side 137. In some embodiments, at least one of the third side137 and fourth side 138 of first activation member 120 can include a slot 139. The slot 139 can be configured to receive a retaining member (not shown) having corresponding dimensions based on the dimensions of slot 139 such that the first activation member 120 can slidably move between the first axial position 188 and the second axial position 190. In some embodiments, the housing 104 can include the retaining member. For example, the retaining member can protrude from the at least one sidewall of housing 104, and the first activation member 120 can be positioned in the housing 104 of device 102 such that the retaining member is arranged in the slot 139 of first activation member 120. In another example, the first activation member 120 at the third side 137 can include a first slot 139a and the first activation member 120 at the fourth side 138 can include a second slot 139b, and the device 102 can include a first retaining member positioned in the first slot 139a and a second retaining member positioned in the second slot 139b to retain the first activation member 120 in the housing 104 while allowing the first activation member 120 to move between the first axial position 188 and the second axial position 190.

[0061] In the figures, it is generally shown that the first activation member 120 slidably moves in an axial direction along the first axis relative to the housing 104 of device 102, and the mechanical linkage of second activation member 140 to first activation member 120 translates the movement into the multiple actuations of energy harvester 106. Although not shown in the figures, it is to be appreciated that the first activation member 120 can be a static member (e.g., first activation member 120 does not move relative housing 104) and instead energy harvester 106 may slidably move in an axial direction along a respective axis relative to the housing 104 of device 102. In this regard, second activation member 140 can be mechanically coupled to energy harvester 106 and mechanically linked to first activation member 120 such that the second activation member 140 can be configured to slidingly move with energy harvester 106 between a first axial position and a second axial position while simultaneously engaging (e.g., contacting) the one or more engagement features of first activation member 120 to cause the second activation member 140 at the first end 144 to move between the first lateral position and the second lateral position to cause the multiple actuations of energy harvester 106. For example, device 102 can include a carriage configured to slidingly move between a first position and a second position along a respective axis relative to housing 104 in response to an actuation, and energy harvester 106, second activation member 140, and second spring element 170 can be arranged on the carriage so that the components move therewith in response to an actuation.
