Description

Technical Field

[0001] The utility model relates to the technical field of touch devices and equipment, in particular to an elliptical touch device. Background Art

[0002] A touch device is an electronic device that can collect and respond to user touch input. It converts the user's physical touch actions into electrical signals by detecting information such as touch position, pressure, and movement, thereby enabling interaction with electronic devices. The elliptical touch device has an elliptical surface shape and uses touch sensing technology to detect and respond to user touch operations on its surface. It is used to control and operate various electronic devices.

[0003] After searching, the Chinese patent with the publication number CN203689484U discloses a touch device. The patent describes a pixel unit provided with an electrochromic layer, a pixel electrode, and a thin film transistor as a pixel electrode switch, wherein the pixel electrode is connected to the electrochromic layer; the touch unit includes a touch drive electrode and a touch sensing electrode arranged with cross insulation, which are used to obtain a touch position; the thin film transistor is used to control the operation of the pixel electrode according to the obtained touch position, so as to apply a drive signal to the electrochromic layer connected to the pixel electrode, and change the color of the electrochromic layer corresponding to the pixel unit according to the touch position, thereby increasing the color change of the touch screen. Since the touch position is obtained by the touch unit, the electrochromic layer corresponding to the touch position can be controlled to change color.

[0026] Example 1: An oval touch device, including a shell 1, a shell 2 2 is installed at the bottom of the shell 1, the shell 1 is the main shell, and the surface is covered with a tempered glass protective layer. This protective layer not only enhances the durability of the device, but also protects the internal precision components from damage during long-term use. A pressure sensor 4 is installed inside the shell 1, a limit plate 5 is installed at the bottom of the pressure sensor 4, a fixing plate 16 is installed at the bottom of the limit plate 5, an upper film 11 is provided at the bottom of the fixing plate 16, an elastic block 12 is installed at the bottom of the upper film 11, and a sensing layer 13 is fixedly connected to the bottom of the elastic block 12. When the user's finger touches the shell 1, the touch pressure is transmitted to the pressure sensor 4 through the tempered glass protective layer. After the pressure sensor 4 detects the touch pressure, it converts it into an electrical signal. At the same time, the touch pressure is further transmitted to The surface of the upper film 11 and the fixed plate 16, the fixed plate 16 is provided with a lower electrode 14 and an upper electrode 15. These electrodes sense the touch position and force through changes in the electrodes. When the touch pressure is transmitted to the elastic block 12, the elastic block 12 is compressed and deformed, and the touch sensing is refined to further improve the accuracy of touch detection. The fixed plate 16 is provided with a lower electrode 14 and an upper electrode 15. The lower electrode 14 is installed on one side of the upper electrode 15. The deformation and touch pressure of the elastic block 12 are finally transmitted to the sensing layer 13. The sensing layer 13 converts the sensed touch information into an electrical signal and transmits it to the control chip inside the shell 2. The control chip processes and analyzes the received electrical signal, and converts data such as touch position and force into touch data recognized by the main control system of the power supply equipment. The main control system takes corresponding actions based on this data.

[0027] Example 2: The difference between this example and Example 1 is that, the interior of the limit plate 5 is fixedly connected to a storage column 10, a spring 9 is installed inside the storage column 10, and the bottom of the limit plate 5 is fixedly connected to a pad 6, wherein the pad 6 provides additional supporting force to ensure the stability of the pressure sensor 4, and the sliding connection mechanism between column 1 7 and column 2 8 ensures that the downstream movement of the limit plate 5 exceeds and is accurate, and the combined design of the spring 9 and the storage column 10 ensures that the device can quickly return to its original state and maintain its height after being subjected to external force, the bottom of the pad 6 is fixedly connected to column 1 7, the top of the inner wall of the limit plate 5 is fixedly connected to column 2 8, column 1 7 is slidably connected to the inside of column 2 8, the storage columns 10 are distributed in a linear array, one side of the shell 2 2 is electrically connected to the connector 3, the surface of the shell 1 is provided with a glass protective layer, and the interior of the shell 2 2 is provided with a control chip.

[0028] When working, the shell 1 is the main shell of the touch device, and the surface is covered with a tempered glass protective layer. This protective layer not only enhances the durability of the device, but also protects the precision components inside. The interior of the shell 1 is equipped with a pressure sensor 4, a limit plate 5, a fixing plate 16, an upper film 11, an elastic block 12 and a sensing layer 13. These components work well to achieve touch detection. When the user's finger touches the shell 1, the touch pressure is transmitted to the pressure sensor 4 through the tempered glass protective layer. After the pressure sensor 4 detects the touch pressure, it converts it into an electrical signal. At the same time, the touch pressure is further transmitted to the surface of the upper film 11 and the fixing plate 16. The fixing plate 16 is internally provided with a lower electrode 14 and an upper electrode 15. These electrodes sense the touch position and force through the changes in the electrodes. When the touch pressure is transmitted to the elastic block 13, the pressure is sensed. When the elastic block 12 is moved, the elastic block 12 is deformed under pressure and the touch sensing is refined, thereby further improving the accuracy of touch detection. The deformation of the elastic block 12 and the touch pressure are finally transmitted to the sensing layer 13. The sensing layer 13 converts the sensed touch information into an electrical signal and transmits it to the control chip inside the shell 2. The control chip processes and analyzes the received electrical signal, and converts the touch position, force and other data into touch data recognized by the main control system of the power supply equipment. The main control system takes corresponding actions based on these data. The pad 6 provides additional support force to ensure the stability of the pressure sensor 4. The sliding connection mechanism between the column 1 7 and the column 2 8 ensures that the downstream movement of the limit plate 5 is more precise, and the combined design of the spring 9 and the storage column 10 ensures that the device can quickly return to its original state and maintain its height after being subjected to external force.
