[0027] The utility model provides a steering wheel integrated with a display screen, comprising a steering wheel body and a circular display screen, wherein the circular display screen is fixed at the center of the steering wheel body, the rotation center of the steering wheel body overlaps with the center of the circular display screen, the circular display screen comprises a circular cover plate and a circular display module, the circular display module is arranged below the circular cover plate, the circular display module is fully bonded to the circular cover plate by optical glue, and an ink layer is arranged on the lower surface of the circular cover plate located in a visible area, and the ink layer is a dot matrix ink.

[0028] Because the ink layer is set in the visible area and the ink layer is dot matrix ink, the light of the circular display screen can pass through the dot matrix gap when it is lit, so that the driver can see the display content; when it is not lit, most of the light is blocked by the dot matrix ink and the circular display screen cannot be seen by the naked eye, and the steering wheel is no different from a normal steering wheel. The steering wheel and the circular display screen are integrated, thereby achieving a stunning display effect and improving the competitiveness of the product.

[0029] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.

[0030] See also Figure 1 and Figure 2 , a steering wheel integrated with a display screen provided by the utility model, comprising a steering wheel body 1 and a circular display screen 2, the circular display screen 2 is fixed at the center of the steering wheel body 1, the rotation center of the steering wheel body 1 overlaps with the center of the circular display screen 2, the circular display screen 2 comprises a circular cover plate 21 and a circular display module 22, the circular display module 22 is arranged below the circular cover plate 21, the circular display module 22 and the circular cover plate 21 are fully bonded by an optical adhesive 23, and an ink layer 24 is arranged on the lower surface of the circular cover plate 21 located in the visible area, and the ink layer 24 is a dot matrix ink. Since the ink layer 24 is arranged in the visible area, and the ink layer 24 is a dot matrix ink, when the circular display screen 2 is lit, light can pass through the dot matrix gap, so that the driver can see the display content; when it is not lit, most of the light is blocked by the dot matrix ink, so that the naked eye cannot see the circular display screen 2, and the steering wheel is no different from a normal steering wheel, and the steering wheel and the circular display screen 2 are integrated, thereby achieving a stunning display effect and improving the competitiveness of the product.

[0031] Furthermore, the size of the dot matrix ink is in the micrometer level, and the side length of each dot matrix ink is 1 μm-20 μm.

[0032] Please combine Figures 1 to 3 Furthermore, since the rotation center of the steering wheel body 1 overlaps with the center of the circular display screen 2, an angle sensor is provided in the steering wheel body 1 or the circular display screen 2, and a control chip is provided in the circular display screen 2. The control chip is electrically connected to the angle sensor. After receiving the angle signal from the angle sensor, the control chip can control the display content of the circular display screen 2 to rotate in the opposite direction to a corresponding angle. When the steering wheel body 1 rotates, the angle sensor built into the steering wheel body 1 will calculate the rotation angle of the steering wheel body 1, and then convert this parameter into a signal and transmit it to the display screen control chip. The display screen control chip rotates the display content of the circular display screen 2 back to the same angle according to the rotation angle of the steering wheel body 1, so that the display content of the circular display screen 2 can always remain vertical relative to the driver. And since the steering wheel body 1 and the circular display screen 2 are both circular, and the refresh frequency of the display screen is generally 60HZ, the driver's naked eyes cannot see the rotation change of the display content of the circular display screen 2. In this way, no matter how the steering wheel body 1 is rotated, the display content of the circular display screen 2 is always presented to the driver in the same position and in the same direction, that is, the display content of the circular display screen 2 always maintains the same position and direction, avoiding the driver's misjudgment due to the rotation of the display content of the circular display screen 2, reducing unnecessary losses, and thus making the product sufficiently competitive to meet the company's growing quality requirements.

[0033] See also Figure 4 As a further optimization scheme of Example 1, in this embodiment, a frame-shaped overflow glue groove 25 is etched on the lower surface of the circular cover plate 21 located in the non-visible area, and a light-shielding ink 26 is provided on the edge of the lower surface of the circular cover plate 21 located in the non-visible area, and the light-shielding ink 26 is coated on the outer surface of the overflow glue groove 25 and the lower surface of the circular cover plate 21. Since the overflow glue groove 25 is provided on the lower surface of the circular cover plate 21, when the optical glue 23 is coated, the optical glue 23 will overflow outward under pressure, and the excess glue will flow to and be stored in the overflow glue groove 25 to prevent it from continuing to diffuse outward, thereby limiting the overflow glue range, which can effectively prevent the optical glue 23 from overflowing and causing light leakage; the edge of the lower surface of the circular cover plate 21 is provided with a light-shielding ink 26, and the light-shielding ink 26 is coated on the outer surface of the overflow glue groove 25 and the lower surface of the circular cover plate 21, and the overflow glue groove 25 is in the light-shielding ink 26 area at the edge of the circular cover plate 21, so it will not affect the appearance of the product.

[0034] Furthermore, the shape of the overflow glue groove 25 can be convenient for etching shape design, and the cross section is not limited to semicircular, V-shaped, etc. The thickness of the circular cover plate 21 commonly used in the industry is about 0.8 mm, the thickness of the optical glue 23 is about 0.1 mm, and the etching depth of the overflow glue groove 25 can be designed to be 0.05 mm, and adjusted according to the actual overflow glue amount.

[0035] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
