## Background
BACKGROUND
1. Technical Field
The present invention relates to toys and, particularly to a dinosaur toy.
2. Discussion of Related Art
Generally, a popular kind of toy is designed in the shape of an animal, for example a dinosaur.
However, animal toys are usually limited in function and children quickly lose interest in the toy. As a result, the toys' ability to assist in the intellectual growth of children is limited.
Therefore, what is needed is an electronic toy with greater number of functions to maintain a child's interest.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Reference will now be made to the drawing to describe the embodiments of the present electronic dinosaur toy, in detail.
In the drawing, an electronic dinosaur toy 10, according to an exemplary embodiment, is provided. The electronic dinosaur toy 10 maybe designed to simulate any other kind of creature, real or imagined, and is built large enough and with strong enough materials to accommodate a child riding thereon. The electronic dinosaur toy 10 includes a body 11, a head 12, a neck 13, four legs 14, and a tail 15. The neck 13, the four legs 14, and the tail 15 are respectively connected to the body 11. The head 12 is connected to the distal end of the neck 13.
The four legs 14 are configured for supporting the body 11, Each of the four legs 14 is equipped with a first actuator 141 and a pressure sensor 142. The first actuators 141 are arranged inside the legs 14 respectively and configured for driving the corresponding legs 14 to move. The first actuators 141 can be piezoelectric actuators or micro-electro-mechanical systems (MEMS) actuators. The pressure sensors 142 are arranged in distal ends of the legs 14 respectively and configured for sensing variations in pressure to any of the legs 14 and outputting feedback signals representative of those variations in response to a user's movements while riding the electronic dinosaur toy 10 or applying pressure by hand. The first actuators 141 are configured for controlling actions of the legs 14 based on the feedback signals. As such, when the user applies pressure to the electronic dinosaur toy 10, for example shills their body while on the electronic dinosaur toy 10, the movement of the electronic dinosaur toy 10 will be adjusted according to the variation of the pressure felt by the pressure sensors 142. For example, when the user mounts the electronic dinosaur toy 10, which is standing upright on a solid relatively level surface, pressure on the legs 14 will increase and he sensed by the pressure sensors 142. Then, the pressure sensors 142 will output a feedback signal, corresponding to the increase in pressure, that causes the first actuators 141 to drive the legs 14 of the electronic dinosaur toy 10 to move in a way that simulates walking and causes the electronic dinosaur toy 10 to move forward at a certain speed. As the electronic dinosaur toy 10 moves, the average magnitude of pressure on the legs 14 remains relatively stable and so, correspondingly. movement of the electronic dinosaur toy 10 remains steady. Different speeds of the electronic dinosaur toy 10 can be obtained by, for example, the user shifting their position, such as leaning forward or leaning back, which then causes pressure on the legs 14 to shift. When the user leans forward, the electronic dinosaur toy 10 can respond with an increase in speed; and when the user leans back, the electronic dinosaur toy 10 can slow down. The electronic dinosaur toy 10 further includes four shoes 143 covering the respective pressure sensors 142.
The electronic dinosaur toy 10 can have additional functional modules as described as below.
The body 11 has a vibrator 111, a multimedia player 112, a storage device 113, a game machine 114, a display device 115, a temperature sensor 116, and a power supply 117 arranged therein. The vibrator 111 is configured for generating a vibration when the user is riding the electronic dinosaur toy 10, to simulate a more life-like feeling. The multimedia player 112 is configured for playing Mp3, Mp4 files and the like. The storage device 113 is configured for storing multimedia files that can be played by the multimedia player 112. The game machine 114 includes a loud speaker (not shown). The loud speaker is configured for generating different sounds when the user wins or loses a game. The display device 115 is arranged at an exterior of the body 11 and configured for displaying information such as images output by the multimedia player 112 and the game machine 114. The temperature sensor 116 is configured for sensing ambient environmental temperature and outputting a feedback signal representative of the ambient environmental to the first actuators 141. Thereby, sensitivity of the first actuators 141 may be adjusted to accomplish different sensitivity in differing temperature environments. The power supply 117 is configured for providing electric power to the electronic dinosaur toy 10.
The head 12 is equipped with a face, a forehead, eyeballs, a mouth, a tongue arranged in the mouth, and a chin. The head 12 has an optical imaging device 121, a second actuator 122, a sensing device 123, a third actuator 124, a voice coil motor 125, a sound generating device 126 and a voice identification device 127 arranged thereon. The optical imaging device 121 is arranged on the forehead and configured for picking up an external image and sending the image to the display device 115 for display. The second actuator 122 and the sensing device 123 are arranged in the chin. The second actuator 122 is configured for driving the chin to move up and down. The sensing device 123 is configured for sensing a location of the chin and outputting a feedback signal representative of the location to the second actuator 122. Thereby, the second actuator 122 actuates the chin to move based on the feedback signal. The sensing device 123 can be a positioning sensor, for example a capacitance type position sensor. The third actuator 124 is arranged in the mouth of the head 12 for driving the tongue to move back and forth. The third actuator 124 can be an electro-active polymer actuator. As such, when different voltages are applied to the electro-active polymer actuator, the tongue is actuated to move back and forth. The voice coil motor 125 is configured for driving the eyeballs to (for example) pop in and/or pop out. The sound generating device 126 is arranged in the mouth of the head 12 and configured for generating simulated dinosaur sounds. The voice identification device 127 is arranged on the face of the head 12 and configured for receiving voice of a user and identifying an identity of the user.
The neck 13 has a fourth actuator 131 and a first motion sensor 132 arranged therein. The fourth actuator 131 is configured for driving the neck 13 to swing. The first motion sensor 132 is configured for sensing a motion state for example slanting or accelerating, of the neck 13 and outputting a feedback signal representative of the motion state to the fourth actuator 131. Thereafter the fourth actuator 131 adjusts a movement of the neck 13 based on the feedback signal. The first motion sensor can be a three-axis accelerometer or a three-gyroscope sensor.
The tail 15 has a fifth actuator 151 and a second motion sensor 152 arranged therein. The fifth actuator 151 is configured for driving the tail 15 to move for example bending, shrinking, extending and/or slanting and so on. The second motion sensor 152 is configured for sensing a motion state of the tail 15 and outputting a feedback signal representative of the motion state to the fifth actuator 151. Thereby the fifth actuator 151 adjusts a movement of the tail 15 based on the feedback signal.
In sum, the electronic dinosaur toy 10 is equipped with many different actuators and pressure sensors, which can cooperatively simulate a creatures movement and sounds, and can even transport a rider. Further, the dinosaur 10 can be equipped with entertaining and/or educational audio and video files for keeping a child's interest for a much longer time than standard animal-like toys.
Finally, it is to be understood that the above-described embodiments are intended to illustrate rather than limit the invention. Variations may be made to the embodiments without departing from the spirit of the invention as claimed. The above-described embodiments illustrate the scope of the invention but do not restrict the scope of the invention.
