[0027] like Figure 1 and 2 As shown, a touch slider module with a guiding function includes a protective cover 110 and a touch slider sensor 130, wherein the touch slider sensor 130 is arranged on the lower surface of the protective cover 110, and the upper surface of the protective cover 110 is provided with a strip slide groove 111 corresponding to the touch slider sensor 130; the surface of the strip slide groove 111 is covered with a varnish layer 140.
[0028] The touch slider module of the utility model is provided with a strip slide groove 111 corresponding to the touch slider sensor 130 on the protective cover 110, and the strip slide groove 111 is used to provide a guiding function for the touch slider sensor 130 during finger sliding operation; at the same time, the varnish layer 140 is used to cover the surface of the strip slide groove 111 to improve the surface flatness and reflection brightness value of the strip slide groove 111, reduce the diffuse reflection effect of the surface of the strip slide groove 111 on light, so that the light reflection effect between the surface of the strip slide groove 111 and the smooth surface of the protective cover 110 is close.
[0029] The varnish layer 140 is a highly transparent synthetic resin, also called surface transparent varnish, commonly known as varnish, which is made of a base material and an additive, and includes two types: UV varnish and PU varnish. The difference between UV varnish and PU varnish lies in the different ways of curing and forming films. After being coated on the surface of the strip slide groove 111, the varnish layer 140 can fill the surface of the strip slide groove 111, improve the surface flatness of the strip slide groove 111, and reduce the diffuse reflection effect of the surface of the strip slide groove 111 on light. The varnish layer 140 is shiny after curing and forming a film, which can improve the reflection brightness value of the strip slide groove 111, making it close to the light reflection effect between the smooth surface of the protective cover plate 110, thereby maintaining the overall visual consistency of the touch screen.
[0030] The strip-shaped slide groove 111 is formed by subtracting the material from the upper surface of the protective cover plate 110 through CNC grinding and grooving, wet etching and grooving, or laser etching and grooving. After CNC grinding and grooving, wet etching and grooving, or laser etching and grooving, the surface of the strip-shaped slide groove 111 is an uneven frosted surface. After the varnish layer 140 is coated on the surface of the strip-shaped slide groove 111, the uneven frosted surface of the strip-shaped slide groove 111 can be filled, the surface flatness of the strip-shaped slide groove 111 can be improved, and the diffuse reflection effect of the surface of the strip-shaped slide groove 111 on light can be reduced.
[0031] The surface of the strip slide groove 111 includes a slide groove bottom surface and a plurality of slide groove side surfaces surrounding the slide groove bottom surface. Preferably, the slide groove bottom surface and the slide groove side surface, and two adjacent slide groove side surfaces are connected by an inner rounded corner surface 112, and the slide groove side surface and the upper surface of the protective cover plate 110 are connected by an outer rounded corner surface 113.
[0032] The utility model connects the bottom surface of the strip slide groove 111 with the side surface of the slide groove, and two adjacent side surfaces of the slide groove are connected by an inner rounded surface 112, and connects the side surface of the slide groove 111 with the upper surface of the protective cover plate 110 by an outer rounded surface 113, which can improve the comfort of fingers when sliding in the strip slide groove 111 and avoid scratches on fingers by the corners of the strip slide groove 111 during sliding operations.
[0033] The strip-shaped slide groove 111 has a length direction X and a width direction Y. The length direction X of the strip-shaped slide groove 111 is parallel to the sliding direction of the touch slider sensor 130, and the width direction Y of the strip-shaped slide groove 111 is perpendicular to the sliding direction of the touch slider sensor 130. The size of the strip-shaped slide groove 111 in the length direction X is greater than its size in the width direction Y.
[0034] Since the length dimension of the strip slide groove 111 is greater than its width dimension, and the length direction X of the strip slide groove 111 is parallel to the sliding direction of the touch slide bar sensor 130, the finger in the strip slide groove 111 cannot slide in the width direction Y of the strip slide groove 111, which is convenient for users, especially drivers, to use finger touch to identify the sliding direction of the touch slide bar sensor 130, so that the finger is inserted into the strip slide groove 111 and is restricted in the strip slide groove 111 due to the special three-dimensional structure design, so that the finger can only slide along the length direction X in the strip slide groove 111.
[0035] The touch slider module further includes an adhesive layer 120 , and the protection cover 110 and the touch slider sensor 130 are bonded and fixed by the adhesive layer 120 .
[0036] In this embodiment, the adhesive layer 120 can be but is not limited to solid OCA or double-sided tape. The touch slider sensor 130 is provided with a driving chip electrically connected to the vehicle-mounted host. After being bonded and fixed to the lower surface of the protective cover 110, it is electrically connected to the vehicle-mounted host through the driving circuit board on the driving chip, so that the touch slider sensor 130 converts the sliding touch signal in the strip-shaped slide groove 111 into an electrical signal and sends it to the vehicle-mounted host. The vehicle-mounted host controls other components of the vehicle system according to the electrical signal, such as controlling the brightness of the screen, the volume of the sound, the air volume of the air conditioner, or the temperature.
[0037] In this embodiment, the touch slider sensor 130 may be a capacitive sensor, an infrared sensor, an optical sensor, etc., and its driver chip communicates with the vehicle-mounted host through an I2C or SPI interface.
[0038] In this embodiment, the protective cover plate 110 may not be limited to a glass cover plate, a plastic cover plate or a sapphire cover plate. Embodiment 2
