technical field

The present invention relates to a touch lens structure, in particular to a touch lens structure with touch sensing and applicable to robot structures.

Background technique

The development of robots, from toys with simple functions at the beginning, to robots with various specific functions with artificial intelligence, has gradually occupied a place in daily life. Today's robot development has been able to collect a large amount of surrounding information, and use various algorithms to judge and trigger various responses, thereby enabling the robot to have more functions. Even a robot positioned as a toy can make various responses through various sensors or internal processing units, which not only increases the fun but also further increases the functionality of the actual operation.

However, not all robots need to install various sensors or detection devices to increase the cost of hardware equipment, but they also need an interface to receive or display information to increase communication between robots and humans. For example, the welcome robot needs to emit sounds or lights to greet guests when they approach, or provide an input interface for selecting services. If a touch panel with a display screen is simply provided, although the same effect can be achieved, it will lose the anthropomorphic service. In this way, if the guests face the computer screen operation, it loses the meaning of setting up a welcome robot. Therefore, how to design the robot structure to achieve the required operation mode of detection and response will be a major focus of the development of these robots.

Taking the existing robot as an example, the head, body, limbs and other parts of the general human are often designed. The shells of these parts are usually only to protect the internal mechanism or electronic equipment of the robot and form the appearance of the corresponding parts. Other special features. If the shell structure can be further designed to have the function of display or induction, it will be helpful for the setting of the aforementioned input and output interfaces. Looking at the above, in the existing robot shell design, other interface settings are not considered. Therefore, the inventors of the present invention have considered and designed a touch lens structure to improve the deficiencies in the prior art, thereby enhancing industrial implementation and utilization.

The light-transmitting structure will be further described in the following embodiments.

Returning to the inner surface 112 of the lens body 11 , which is the back surface of the light-transmitting structure, originally the housing was only a partition surface for blocking the external light-transmitting part and the internal mechanism, but in this embodiment, a conductive layer 13 is provided on the inner surface 112 superior. The conductive layer 13 can cover the entire inner surface 112 of the entire lens body 11 according to requirements, that is, when any part outside the entire lens body 11 is not touched, the inner conductive layer 13 will be driven. However, the present invention is not limited to this, the conductive layer 13 may also be smaller than the inner surface 112 and only cover part of the inner surface 112 . Relatively, the lens body 11 can only trigger a touch response when the corresponding part is touched.

In this embodiment, the conductive layer 13 is a whole-surface metal conductive sheet, such as a copper foil conductive sheet, an aluminum foil conductive sheet, or other conductive metal foils, which can be attached to the inner surface 112 . When the lens body 11 is touched and squeezed, the conductive sheet of the conductive layer 13 will also deform correspondingly, thereby driving the contact member 14 to trigger the touch response. In this embodiment, the contact piece 14 is a transmission chain, one end of which is connected to the upper end of the conductive layer 13 through a metal ring 141 , the connecting piece of the conductive layer 13 is locked by a screw 142 , and the other end can be connected by a spring sheet or a switch For the touch signal transmitter, when the conductive layer 13 is deformed by the touch, the transmission chain 141 is driven, so that the driving signal transmitter transmits the touch signal.

In other words, by controlling the type and color of the light source generated by the light-emitting diode 12 and setting different light-transmitting structures 114 , the robot can produce different color light, and even display a specific image, forming a specific lens luminous structure.

For displaying or presenting different colors and images through the lens, the robot sets the interface as output, and the light-transmitting structure 114 can present the output information, but to interact with the robot, an input interface is still required. Unlike a general computer, the robot has an input interface such as a mouse keyboard or a touch screen, and the input information can be achieved by the touch lens 10 of this embodiment. For example, when the light-transmitting structure displays a specific color that needs to be selected, the selection can be completed by contacting and pressing the touch lens 10, and the conductive layer 13 drives the touch signal generator to send a signal. Compared with the existing button design or other external input interfaces, the operation of the touch lens 10 of this embodiment is more direct and convenient for the user.

When the conductive layer 23 is deformed by the touch, the contact piece 24 is brought into contact with the elastic piece 241 , so that the driving signal transmitter transmits the touch signal.

In other embodiments, the conductive layer 23 can be a thin-film conductive film. For example, the conductive material is sprayed onto the film by conductive paint or directly sprayed onto the inner surface to form a conductive film. When the conductive film drives the contact piece 24 to be in contact with the elastic sheet 241, it can also be driven to generate a touch signal.

Please refer to FIG. 4 , which is a schematic diagram of a touch lens according to another embodiment of the present invention. As shown in the figure, the touch lens 20 is a touch lens 20 with the same structure as the previous embodiment. After the touch lens 20 is assembled, it can be installed on the front end of the robot arm as a casing of the robot arm. The light emitting diode 22 is disposed on the substrate 221 and placed in the light incident structure 211 of the lens body 21 . By controlling the type and color of the light source generated by the light emitting diode 22 and setting it through different light-transmitting structures 213 , the robot arm can generate light of different colors, and even display a specific image to form a specific lens light-emitting structure.

The touch lens 20 can be mounted on the robotic arm member of the robot by the engaging member 214 on the side of the lens body 21 , and the light-transmitting structure 213 at the outer end of the touch lens 20 can display or present different colors and images as an output interface of the robot.
