[0040] 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.

[0041] As mentioned in the background art, the existing capacitive touch screen only has a touch function, and its functionality is relatively simple.

[0042] In order to solve this technical problem, the utility model provides a touch screen structure with a light guide lamp, which is applied to a vehicle-mounted central control.

[0043] Specifically, please refer to Figure 1-8 The structure of the touch screen with light guide lamp specifically includes:

[0044] The cover plate 1 has through grooves 11 on both sides thereof;

[0045] The bracket 2 is provided on the surface of the cover plate 1 through the through slot 11;

[0046] A light guide plate 3, which is disposed on one side of the cover plate 1 and is connected to the two brackets 2;

[0047] The light emitting structure 4 is arranged in the bracket 2 and scatters light to the surroundings through the light guide plate 3 to form a light emitting body.

[0048] The structure of the touch screen with light guide lamp provided by the utility model is that the light guide plate 3 is arranged on one side of the cover plate 1, so that the light guide plate 3 can guide and disperse the light emitted by the light emitting structure 4 in the distribution bracket 2 on both sides thereof, so that the light is diffused inside the vehicle body through the light guide plate 3, thereby increasing the illuminated area of ​​the interior space of the vehicle, and at the same time realizing the lighting function of the touch screen itself, thereby increasing the versatility of the touch screen.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] Example 1

[0053] Please refer to Figure 1-Figure 4 A structure of a touch screen with a light guide lamp, comprising a cover plate 1, on both sides of which are respectively provided with through grooves 11; a bracket 2, which is arranged on the surface of the cover plate 1 through the through grooves 11; a light guide plate 3, which is arranged on one side of the cover plate 1 and is connected to the two brackets 2; a light emitting structure 4, which is arranged in the bracket 2 and scatters light to the surroundings through the light guide plate 3 to form a light emitting body; the bracket 2 and the light guide plate 3 are fixedly connected, such as Figure 2 As shown, the bracket 2 is arranged inside the cover plate 1 through the through slot 11, so that the plug-in assembly of the bracket 2 and the cover plate 1 is convenient, and at the same time, the stability of the overall installation and use of the light guide plate 3 is improved by two relatively parallel brackets 2;

[0054] The cover plate 1 is composed of a cover plate ink area 12 and a cover plate viewing area 13, wherein the cover plate viewing area 13 is located at the center of the cover plate ink area 12, and the light emitting structure 4 includes a lamp bead 41 and a power supply wire 42 connected to the lamp bead 41;

[0055] The lamp bead 41 is arranged in the bracket 2 at a position relative to the end of the light guide plate 3, and the free end of the power supply wire 42 extends toward the inside of the bracket 2 and is discharged through the wire arrangement groove 43;

[0056] like Figure 3 and Figure 4 As shown, since the cable groove 43 is arranged at the end of the bracket 2, the discharged power wire 42 can be placed on the inner side of the cover plate 1 to improve the overall aesthetics of the display screen, and at the same time, the power wire 42 can be distributed inside the center console on the vehicle body to connect it with the corresponding controller. Since the power wire 42 is arranged inside the bracket 2, it can also be protected.

[0057] Example 2

[0058] The structure of the touch screen with light guide lamp provided in Example 1 is further optimized. Specifically, Figure 4 As shown, the cable groove 43 is located on the outside of the bracket 2, and the power wire 42 after being discharged is located on the back of the cover 1, and the lamp beads 41 are composed of a plurality of LED lamp beads arranged in a ring shape, and two groups of lamp beads 41 are just distributed inside the bracket 2 at both ends of the light guide plate 3;

[0059] The outer side of the bracket 2 is black (i.e., opaque), and the inner side of the bracket 2 is normal light-transmitting white, so that the light generated by the lamp bead 41 can be transmitted to the light guide plate 3 to form a dispersion of the light source. The bracket 2 is made of plastic, so it has good toughness and strength, allowing it to be bent to a certain extent.

[0060] Through the above structural design, the plastic bracket 2 leads out the positive and negative power wires 42 through the cable groove 43 to connect to the external power supply so as to control the current intensity to control the light intensity, thereby improving the operator's operability of the light intensity.

[0061] At the same time, the positions of the left and right LED lamp beads of the light guide plate 3 must be symmetrical to ensure uniform light.

[0062] Example 3

[0063] The structure of the touch screen with light guide lamp provided in Example 2 is further optimized, such as Figure 1-3 As shown, both ends of the light guide plate 3 of the structure of the touch screen with light guide lamp extend 3 to 5 cm from the edge of the cover plate viewing area 13;

[0064] The length is 50~300cm (depending on the size of the central control screen, ensuring sufficient length to achieve a beautiful effect), the thickness is 0.5~2cm, and the material is acrylic / PC sheet;

[0065] By extending the two ends of the light guide plate 3 outside the cover plate viewing area 13, the overall proportion of the display screen is matched, and the light source diffused by the light guide plate 3 can be completely irradiated on the entire cover plate viewing area 13, thereby supplementing the light source inside the vehicle body while satisfying the illumination of the cover plate viewing area 13;

[0066] Furthermore, by extending the light guide plate 3 to the cover plate viewing area 13, the bracket 2 connected thereto can be distributed on both sides of the cover plate viewing area 13 and penetrated through the cover plate ink area 12, thereby avoiding obstruction of the line of sight of the cover plate viewing area 13, which is conducive to the driver's better viewing of the display screen.

[0067] For the above-mentioned embodiments 1 to 3, the use process of the structure of the touch screen with light guide lamp provided by the utility model is as follows: the lamp bead 41 is powered on and illuminated through the power light guide 42. During the illumination process, the light generated by the lamp bead 41 will be transmitted to the inside of the light guide plate 3, and the light source will be further dispersed through the light guide plate 3 to form an illumination effect on the interior space of the vehicle body.

[0068] Example 4

[0069] The structure of the touch screen with light guide lamp provided in Example 1 is further optimized, such as Figure 5-Figure 8 As shown, both ends of the light guide plate 3 are connected to the corresponding bracket 2 through the buckle assembly 5;

[0070] The buckle assembly 5 includes a male buckle 51 and a female buckle 52, the male buckle 51 is connected to one end of the light guide plate 3, and the female buckle 52 is connected to the inner side of the bracket 2;

[0071] The male buckle 51 is symmetrically provided with fasteners 53 inside, and the female buckle 52 is formed with an entry groove 54 at the position corresponding to the fastener 53, and the female buckle 52 is also provided with a screw-in groove 55 connected thereto at the position corresponding to the entry groove 54. The overall length of the light guide plate 3 plus the male buckles 51 on both sides is exactly the same as the relative distance between the two brackets 2. By setting this distance, when installing the light guide plate 3, the front ends of the two brackets 2 must first be bent apart at a certain angle, and then the light guide plate 3 is placed on the inner side of the two brackets 2. After the force on the brackets 2 is released, the brackets 2 can be elastically reset so that they are still parallel to each other. Therefore, the reset brackets 2 can achieve the initial fixation of the light guide plate 3 therein by their own force, that is, the initial limit of the fastener 53 placed in the corresponding position in the entry groove 54, which facilitates the subsequent rotation and further tightening operation;

[0072] By setting the buckle assembly 5, the rotation of the light guide plate 3 inside the two brackets 2 is realized, and the brackets 2 have elastic characteristics, so that the light guide plate 3 after the rotation contact can be taken out from the inside of the brackets 2, so as to form a replacement operation of the light guide plate 3;

[0073] Specifically, after aligning the fastener 53 on the male buckle 51 with the insertion groove 54 in the female buckle 52, the light guide plate 3 is rotated so that the male buckle 51 on it drives the fastener 53 therein to rotate synchronously in the screw-in groove 55. When the light guide plate 3 is rotated to 90 degrees, the fastener 53 rotates to the end in the screw-in groove 55. At this time, the male buckle 51 and the female buckle 52 form a relative locking state, that is, the light guide plate 3 and the bracket 2 form a locking state.

[0074] Similarly, the light guide plate 3 is rotated in the opposite direction by 90 degrees, so that the fastener 53 in the screw-in groove 55 is rotated and reset to the position corresponding to the groove 54, and then the brackets 2 on both sides can be moved to produce a certain elastic deformation, so that the fastener 53 can be separated from the groove 54 to remove or replace the light guide plate 3.

[0075] Example 5

[0076] The structure of the touch screen with light guide lamp provided in Example 4 is further optimized, such as Figure 1 As shown, a buckle groove 56 is formed at the end of the screw-in groove 55, and an elastic convex ball 57 adapted to the buckle groove 56 is formed at the position of the buckle 53 corresponding to the buckle groove 56. The elastic convex ball 57 has a certain elasticity. The elastic convex ball in this embodiment is made of rubber;

[0077] During the process of rotating the light guide plate 3 to lock it, the elastic convex ball 57 is deformed by the resistance force of the inner wall of the screw-in groove 55. When the light guide plate 3 is rotated to ninety degrees and the fastener 53 thereon is rotated to the end of the screw-in groove 55, the elastic convex ball 57 is not affected by the resistance force of the inner wall of the screw-in groove 55 and is reset in the fastener groove 56, which further improves the mutual locking stability between the fastener 53 and the fastener groove 56, making the light guide plate 3 installed more firmly and not prone to autonomous rotation displacement and falling off.

[0078] For the above-mentioned Embodiments 4 and 5, the use process of the structure of the touch screen with a light guide light provided by the utility model is as follows: after the front ends of the two brackets 2 are swung outward at a certain angle, the light guide plate 3 is placed on the inner side of the two brackets 2. During the placement process, the male buckles 51 and the female buckles 52 at both ends of the light guide plate 3 are set correspondingly, that is, the fasteners 53 and the positions of the slots 54 are matched, and then the brackets 2 are released. After the initial positioning of the light guide plate 3 is formed by the restoring force of the brackets 2 themselves, the light guide plate 3 is then rotated ninety degrees. At this time, the fasteners 53 are rotated to the end in the screw-in slots 55. At this time, the male buckle 51 and the female buckle 52 form a relative locking state, that is, the light guide plate 3 and the bracket 2 form a locking state. Conversely, the light guide plate 3 can be contacted by rotating the light guide plate 3 in the opposite direction to perform the replacement operation.
