Detailed Description

Various preferred embodiments of the present invention will be described below with reference to the accompanying drawings. The following description with reference to the accompanying drawings is provided to assist in understanding the exemplary embodiments of the invention as defined by the claims and their equivalents. It includes various specific details to assist understanding, but they are to be construed as merely illustrative. Accordingly, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Also, in order to make the description clearer and simpler, a detailed description of functions and configurations well known in the art will be omitted.

First, a mouse according to the present invention will be described with reference to fig. 1. According to the utility model discloses a mouse does not have the connecting wire, its and an information processing equipment wireless connection. Fig. 1 is a functional block diagram showing a configuration of a mouse according to the present invention. As shown in fig. 1, the mouse includes: a roller 10, an electric power generation device 20, and an electric power storage device 30.

The wheel 10 is used for receiving operation input of a user. For example, by dialing the wheel 10 with a finger to rotate forward or backward while the user is browsing a web page or text.

The power generation device 20 is used for converting mechanical energy during the operation of the mouse into electric energy. Specifically, during operation of the mouse, rotation of the scroll wheel and sliding of the mouse are typically involved. When the mouse wheel is operated by the user to rotate, the electric energy generating device 20 can convert the mechanical energy of the rotation of the wheel into electric energy. When the user operates the mouse slide, the power generation device 20 may convert the mechanical energy of the mouse slide into the electric energy. Specific details regarding energy conversion will be described below.

The electric energy storage device 30 is used for storing the electric energy generated by the electric energy generating device 20 after predetermined processing so as to supply power to the mouse. For example, the electrical energy storage device 30 may further include: the amplifying circuit is used for amplifying the current signal generated by the electric energy generating device; the alternating current-direct current conversion circuit is connected with the amplifying circuit and is used for converting the alternating current signal into a direct current signal; the energy storage circuit is used for receiving and storing the power supply signal output by the alternating current-direct current conversion circuit; and the wireless transceiving circuit is connected with the energy storage circuit and used for receiving and outputting the power supply signal.

Fig. 2 shows a schematic structural diagram of a mouse wheel according to the present invention, which is a side view based on a side view of a mouse. As shown in fig. 2, a first magnetic element 101 is provided on the roller 10 at one radial edge from the center of rotation. When the user operates the mouse wheel, the first magnetic element 101 rotates to a different position along with the rotation of the wheel. In fig. 2, the first magnetic element is shown disposed at only one radial edge position on the circumference of the roller 10, although the present invention is not limited thereto. Alternatively, a plurality of first magnetic elements may be provided at a plurality of radial edges (e.g., two diametrically opposed radial edges) of the roller.

Fig. 3 shows a specific configuration of the electric energy generating apparatus of the mouse according to the present invention, which is a top view based on the viewing angle above the mouse. As shown in fig. 3, the electric power generation device 20 includes: the magnetic valve comprises a closed hollow cylinder 201, a second magnetic element 202, a first elastic element 203 and a spiral coil 204.

The hollow portion of the closed hollow cylinder 201 is used to form a slide guide space.

The second magnetic element 202 is disposed in the slide guide space and is freely slidable therein. In fig. 3, the magnetism of the portion with the hatching pattern is opposite to that of the portion without the hatching pattern. For example, the shaded portion is the N pole, and the unshaded portion is the S pole.

The first end of the first elastic element 203 is fixed at the first end of the closed hollow cylinder, and the second end of the first elastic element is connected with the first end of the second magnetic element. For example, as one possible embodiment, the first elastic element is a spring.

The helical coil 204 is made of a conductive material and is wound around a portion of the outer surface of the closed hollow cylinder. In fig. 3, the winding of a helical coil on the outer surface of the left part of the closed hollow cylinder is shown. Of course, the present invention is not limited thereto, and the helical coil may be wound on the outer surface of the right portion or the outer surface of the middle portion of the closed hollow cylinder.

In addition, the electric power generation apparatus 20 further includes: a detecting element (not shown in the figure) for detecting parameters during the operation of the mouse; and a switching mechanism (not shown) for switching the closed hollow cylinder between a first state and a second state.

When the parameters detected by the detection element meet the preset conditions, the closed hollow cylinder is switched to the first state, and the central axis of the closed hollow cylinder is vertical to the central axis of the roller in the first state; and when the parameter detected by the detection element does not meet the preset condition, switching the closed hollow cylinder to the second state, wherein the central axis of the closed hollow cylinder is parallel to the central axis of the roller in the second state.

The central axis of the closed hollow cylinder is perpendicular to the central axis of the roller in the first state, and the central axis of the closed hollow cylinder is parallel to the central axis of the roller in the second state, in other words, the closed hollow cylinder in the second state is rotated by 90 degrees compared to the closed hollow cylinder in the first state. Therefore, the switching mechanism included in the electric power generation device may be any mechanical structure capable of performing a rotational operation of a predetermined angle.

For example, as a possible embodiment, the detection element may comprise an acceleration sensor for detecting an acceleration during operation of the mouse. In this case, the predetermined condition is that the accelerations detected by the acceleration sensors are all equal to zero for a predetermined period of time. Specifically, in the process of operating the mouse by the user, there are generally three types of actions of scrolling the scroll wheel, pressing the left and right buttons, and sliding the mouse. When the user scrolls the scroll wheel or presses the left key and the right key, the mouse remains stationary and therefore its acceleration is zero. When the user slides the mouse, the acceleration of the mouse is greater than zero. The first state is a state of the sealed hollow cylinder to be set when the mouse is stationary, and the second state is a state of the sealed hollow cylinder to be set when the mouse slides.

Next, a specific process of converting mechanical energy into electrical energy during operation of the mouse will be described. First, a specific operation process of the power generation apparatus when the mouse is stationary is described with reference to fig. 4A, 4B, 5A, and 5B. Fig. 4A and 4B respectively show two states during rotation of the wheel, which are side views based on the side angle of the mouse. In fig. 4A and 4B, the arrow indicates the rotation direction. Fig. 5A and 5B are schematic structural diagrams of a mouse according to the present invention, which is a top view based on an upper viewing angle of the mouse. Since the electric energy storage device is not involved in describing the specific operation of the electric energy generation device, the electric energy storage device is not shown in fig. 5A and 5B. Moreover, for the sake of simplicity, fig. 5A and 5B also omit illustrations of conventional devices in other mice that are not directly related to the self-powered system of the present invention.

In fig. 5A and 5B, a case where the hermetically sealed hollow cylinder in the power generation apparatus is in the first state when the mouse is moved is shown. As can be seen from fig. 5A and 5B, in the first state, the central axis aa 'of the closed hollow cylinder is perpendicular to the central axis bb' of the roller. In the first state, by setting the hermetically closed hollow cylinder to the state as shown in fig. 5A and 5B, in response to the rotation of the roller, the second magnetic element is subjected to alternate action of the magnetic force of the first magnetic element and the elastic force of the first elastic element, slides reciprocally in the slide guide space, causing a change in the magnetic flux passing through the helical coil, and inducing current in the helical coil.

In addition, in order to maximize the magnetic force between the first magnetic element and the second magnetic element, as shown in fig. 5A and 5B, in the second state, an extension line of the central axis of the closed hollow cylinder passes through the roller in a radial direction of the roller.

Also, in order to maximize the magnetic force between the first magnetic element and the second magnetic element, as shown in fig. 5A and 5B, in the second state, the second end of the closed hollow cylinder may be placed closer to the roller than the first end.

The states of the rollers shown in fig. 4A and 4B correspond to the states of the closed hollow cylinders shown in fig. 5A and 5B, respectively. In fig. 4A and 4B, the first magnetic element shown in hatching has the same magnetism as that of the portion of the second magnetic element shown in hatching in fig. 5A and 5B.

Specifically, fig. 5A shows the state of the mouse at the current time point. Corresponding to the roller state of fig. 4A, it can be seen that the first magnetic element in the roller is at a position away from the second magnetic element in the enclosed hollow cylinder. At this time, there is no interaction force between the first magnetic element and the second magnetic element. Thus, the first elastic element is in a free state. Fig. 5B shows the state of the mouse at the next time point. Corresponding to the roller state of fig. 4B, it can be seen that the first magnetic element in the roller rolls to a position close to the second magnetic element in the closed hollow cylinder. At this time, the first magnetic element and the second magnetic element generate a repulsive force when they are close to each other because the magnetic properties are the same. Thus, the first elastic element is in a compressed state.

Then, after the state shown in fig. 5B, the roller may continue to rotate, for example, when the roller rotates to a position away from the second magnetic element in the closed hollow cylinder, the second magnetic element is subjected to the elastic force of the first elastic element to slide toward the direction close to the roller; when the roller rotates to a position where the first magnetic element is close to the second magnetic element in the closed hollow cylinder, the second magnetic element slides towards a direction far away from the first magnetic element to compress the first elastic element. In this way, the second magnetic element reciprocates in the closed hollow cylinder in cycles along with the rolling of the roller, so that the magnetic flux passing through the spiral coil is changed, and an induced current is generated in the spiral coil.

Although in fig. 4A to 5B, the case where the magnetism of the first magnetic element is the same as that of the second magnetic element is shown. However, the present invention is not limited to this. It will be appreciated by those skilled in the art that the situation where the first magnetic element is magnetically opposite to the second magnetic element may be similarly applied to the present invention.

Next, a specific operation process of the power generation device when the mouse is moved is described with reference to fig. 6A and 6B.

Fig. 6A and 6B are schematic structural diagrams of a mouse according to the present invention, which is a top view based on an upper viewing angle of the mouse. Similarly to fig. 5A and 5B, since the electric energy storage device is not involved in describing the specific operation of the electric energy generation device, the electric energy storage device is not shown in fig. 6A and 6B. Moreover, for the sake of simplicity, fig. 6A and 6B also omit illustrations of conventional devices in other mice that are not directly related to the self-powered system of the present invention.

In fig. 6A and 6B, a case where the hermetically sealed hollow cylinder in the electric power generating apparatus is in the second state when the mouse is moved is shown. As can be seen from fig. 6A and 6B, in the second state, the central axis aa 'of the closed hollow cylinder is parallel to the central axis bb' of the roller. In the sliding process of the mouse, sliding in the horizontal direction (left-right direction) is often performed. In the second state, by setting the hermetically closed hollow cylinder to the state as shown in fig. 6A and 6B, the second magnetic element slides reciprocally in the slide guide space in response to the movement of the mouse, causing a change in magnetic flux passing through the helical coil and generating an induced current in the helical coil.

Specifically, fig. 6A shows a state of the mouse at the present time point when the first elastic member is in a free state, and fig. 6B shows a state of the mouse at the next time point when the first elastic member is in a compressed state. For example, the mouse can slide to the left in an accelerated manner, and at this time, the second magnetic element inside the sealed hollow cylinder will also slide to the left, and further the first elastic element is compressed to be in a compressed state, so that the change from fig. 6A to fig. 6B can be realized. When the mouse does not slide to the left any more, for example, when the mouse further slides to the right at an accelerated speed, the second magnetic element inside the closed hollow cylinder will also slide to the right, and the first elastic element is restored to the free state and even further in the stretching state. That is, when the sealed hollow cylinder is in the second state, the mouse can be converted into the left-right movement of the second magnetic element in the sealed hollow cylinder by sliding left and right. When the second magnetic element moves left and right in the closed hollow cylinder, the magnetic flux passing through the spiral coil is changed, and thus an induced current is generated in the spiral coil.

Furthermore, in the above figures only one elastic element is shown arranged in the closed hollow cylinder. However, the present invention is not limited to this. It will be appreciated by those skilled in the art that two elastic elements may also be provided in the closed hollow cylinder. Specifically, in addition to the first elastic element, a second elastic element may be further disposed in the closed hollow cylinder, a first end of which is fixed to a second end of the closed hollow cylinder, and a second end of which is connected to a second end of the second magnetic element. In other words, two elastic elements are respectively fixed at two ends of the closed hollow cylinder, and the second magnetic element is connected between the two elastic elements. A mouse having the configuration described above may also be similarly adapted to the power generation process described above.

Heretofore, a mouse according to the present invention has been described in detail with reference to fig. 1 to 6B. According to the utility model discloses an in the mouse, through adjusting airtight hollow cylinder's state appropriately, can be respectively with the mouse when static rolling mechanical energy of gyro wheel and the mechanical energy conversion of mouse during motion for the electric energy to supply mouse normal operating to use.
