[0041] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0042] As mentioned in the background art, the traditional touch screen itself has a relatively monotonous appearance and has no additional functions except for touch display, which makes it incompatible with the personalized needs of users. Therefore, a touch screen structure with a color light guide is proposed.

[0043] In order to solve this technical problem, the utility model provides a touch screen structure with a color light guide lamp, which is applied to a vehicle-mounted touch screen.

[0044] Specifically, please refer to Figure 1-Figure 8 The touch screen structure of the color light guide lamp specifically includes:

[0045] A touch screen 1, wherein a display area 11 is provided on the surface of the touch screen 1;

[0046] The mounting grooves 12 are distributed on both sides below the display area 11 and formed on the touch screen 1;

[0047] The housing 2 is mounted on the touch screen 1 through the mounting groove 12, and a prism 21 is mounted on one side of the housing;

[0048] The light emitting element 3 is disposed inside the housing 2 and is used for emitting light. The emitted light is refracted into colored light by the prism 21 .

[0049] The touch screen structure of the colored light guide provided by the utility model adds a light emitting element 3 outside the display area 11 of the touch screen 1, so that when the backlight LED lamp 31 is working, the divergent light will be directly irradiated onto the prism 21 through the action of the light guide column 32. At this time, the light is diverged by the prism 21, so that the light is emitted in the form of colored light, so that the area space inside the car can be supplemented with light, while at the same time the diversity of the in-vehicle entertainment system is improved, meeting the personalized needs of some people.

[0050] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0051] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0052] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0053] Please refer to Figure 1-Figure 2 A touch screen structure with a color light guide, comprising a touch screen 1, a display area 11 being arranged on the surface of the touch screen 1; mounting grooves 12 being distributed on both sides below the display area 11 and formed on the touch screen 1; a housing 2 being assembled on the touch screen 1 through the mounting grooves 12, and having a prism 21 mounted on one side thereof; a light emitting element 3 being arranged inside the housing 2 for emitting light, and the emitted light being refracted into color light by the prism 21; the light emitting element 3 comprising a backlight LED lamp 31 and a light guide column 32; wherein the backlight LED lamp 31 is arranged on the other side of the housing 2 and connected to a control module in a car through a wire, and the light guide column 32 is arranged between the backlight LED lamp 31 and the prism 21, so that the light is directly irradiated onto the prism 21;

[0054] The housing 2 in this embodiment is directly fixed inside the mounting slot 12;

[0055] The backlight LED lamp 31 in this embodiment is a light emitting diode LED, and the light source contains all bands of visible light;

[0056] The present embodiment further optimizes the structure of the light emitting element 3. Specifically, the structure of the light emitting element 3 is composed of a backlight LED lamp 31 and a light guide column 32. The backlight LED lamp 31 can provide initial vehicle light, and the light guide column 32 on one side can guide the light emitted by the backlight LED lamp 31 to directly hit the prism 21, thereby satisfying the requirement of refracting the light into colored light.

[0057] like Figure 2 As shown, during the installation of the above-mentioned backlight LED lamp 31, the wires connected thereto pass through the left side and are connected to the vehicle-mounted module. In actual application, the current intensity can also be controlled by the vehicle-mounted module to control the light intensity. The above-mentioned technology is a mature and complete existing technology and is not further elaborated in this embodiment. In the actual connection process, a certain length of wire can be reserved on one side of the backlight LED lamp 31 to meet the adjustment of the light angle and position in subsequent embodiments.

[0058] The touch screen structure of the color light guide lamp provided in Example 1 is further optimized. Specifically, Figure 4 As shown, one side of the housing 2 has an opening slot 22, and a blocking cover 23 is engaged in the opening slot 22;

[0059] Side plates 24 are fixed on both sides of the prism 21, and the prism 21 is fixed to the side wall of the housing 2 through the side plates 24;

[0060] Through the above structural design, the blocking cover 23 can be arranged in the opening groove 22 to protect the structure inside the shell 2. At the same time, the blocking cover 23 can be removed to expose the internal structure of the shell 2, thereby facilitating its subsequent replacement and maintenance.

[0061] The side plate 24 serves as a carrier connected between the prism 21 and the shell 2, which not only improves the position limitation of the prism 21 itself, making it more stable in the actual light divergence process, but also avoids direct contact between the prism 21 body and the inner wall of the shell 2, which is beneficial to the protection and use of the prism 21.

[0062] The touch screen structure of the color light guide lamp provided in Example 1 or 2 is further optimized, such as Figure 3-Figure 8 As shown, a sleeve 4 is sleeved on the surface of the housing 2, and the sleeve 4 is fixed in the mounting groove 12, wherein a universal element 5 is installed in the sleeve 4 for adjusting the irradiation angle of the light emitting element 3;

[0063] The difference between this embodiment and the embodiments 1 and 2 is that the mounting groove 12 in this embodiment is used to directly fix with the sleeve 4, and the housing 2 is placed inside the sleeve 4 and connected with the sleeve 4 through the universal element 5;

[0064] The universal element 5 in this embodiment includes a slide rail 51 fixed to the top wall of the sleeve 4 and a slider 52 slidably arranged inside the slide rail 51. The slider 52 can slide along the slide rail 51 along the length direction of the sleeve 4 to adjust the telescopic distance of the universal element 5.

[0065] Since a certain length of wire is reserved during the actual installation of the backlight LED lamp 31 in the above-mentioned embodiment 1, the shell 2 is pulled outward from the sleeve 4, and the shell 2 slides relative to the slide rail 51 through the slider 52, so that the end of the shell 2 can slide outward to a certain distance. This distance can be used to adjust the irradiation position of the light-emitting element 3, and it is also convenient for further adjustment of the irradiation angle range of the light-emitting element 3 in subsequent embodiments.

[0066] The touch screen structure of the color light guide lamp provided in Example 3 is further optimized, such as Figure 3-Figure 8 As shown, a slot 53 is provided inside the slider 52, and a universal ball 54 fixed to the top of the housing 2 is embedded in the slot 53;

[0067] The universal ball 54 can rotate inside the slot 53, so that the angle between the housing 2 and the sleeve 4 can be adjusted, thereby adjusting the light irradiation angle of the light emitting element 3 to achieve the use of fill light in a wider range inside the vehicle;

[0068] At the same time, when the shell 2 is placed inside the sleeve 4, the end of the shell 2 itself is limited by the internal space of the sleeve 4, resulting in a limited range of angle adjustment. Therefore, the shell 2 can be pulled outward by the slide rail 51 to a certain distance, and then the angle of the shell 2 and the light-emitting element 3 inside it can be adjusted. This operation improves the range of angle adjustment of the light-emitting element 3 to a certain extent, and better meets the needs of some users for personalized adjustment.

[0069] As a further optimization in this embodiment: an anti-skid pad layer 55 is filled between the universal ball 54 and the slot body 53. When the universal ball 54 and the slider 52 rotate relative to each other to adjust the angle of illumination of the light-emitting element 3, the anti-skid pad layer 55 increases the relative friction between the universal ball 54 and the slot body 53, thereby ensuring the stability of the position of the universal ball 54 and its upper shell 2 after the angle adjustment.

[0070] The touch screen structure of the color light guide lamp provided in Example 4 is further optimized, such as Figure 3-Figure 8 As shown, a dustproof element 6 is also provided on the surface of the housing 2 to protect the opening of the sleeve 4;

[0071] The dustproof element 6 includes a dustproof cover 61. A channel 62 for accommodating the housing 2 is formed on the inner side of the dustproof cover 61. An inner connecting ring 63 is fixed in the channel 62. The dustproof cover 61 is a flexible structure and has a certain wrinkled area (not shown in the figure). For details, please refer to the dustproof cover on the gear lever in the car.

[0072] Among them, an outer connecting ring 64 is fixed to the outer side of the dust cover 61, and the outer connecting ring 64 forms a sliding assembly with the outer side of the slide rail 51, while the inner connecting ring 63 is fixed on the housing 2 to form a blocking structure;

[0073] During the process of adjusting the angle of the shell 2 in the sleeve 4, the moving shell 4 will synchronously drive the dust cover 61 thereon to adaptively deform, thereby satisfying the effect that the dust cover 61 can seal and protect the inside of the sleeve 4. At the same time, when the shell 2 moves outward to further increase the illumination angle of its light-emitting element 3, the dustproof element 6 can also slide synchronously through the external connecting ring 64 thereon to meet its synchronous dustproof requirements without forming an obstacle to the movement of the shell 2 when it slides.

[0074] The use process of the touch screen structure of the color light guide lamp provided by the utility model is as follows:

[0075] According to the area space to be illuminated inside the car, the position of the shell 2 is adjusted inside the sleeve 4. After it is moved to a suitable position, the shell 2 is rotated so that the universal ball 54 thereon and the corresponding slider 52 form a relative rotation, so that the angle of the shell 2 is adjusted, and then the backlight LED lamp 31 is started. The light emitted by it is irradiated on the corresponding prism 21 through the light guide column 32. The emission of the prism 21 finally irradiates the designated area inside the car with colored light.
