In the description of this specification, the description referring to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0026] In the present utility model, as Figure 1-2 shown, there is provided a ground variable sign for lane guiding, including: a substrate 1, the substrate 1 can be fixed on the road surface; an upper plate 2, the upper plate 2 can be installed on the top surface of the substrate 1, the upper plate 2 is provided as a steel plate, and the upper plate 2 is provided with light-transmitting holes 3 at intervals along a set path; a lighting member, the lighting member includes a plurality of lamp beads 4, a PU glue 5 connecting the lamp beads 4 to the upper plate 2, and each of the lamp beads 4 corresponds to a position of one of the light-transmitting holes 3.

[0027] For the variable sign of the present utility model, when installing, after installing the substrate 1 on the road surface, the upper plate 2 can be directly fixedly installed on the substrate 1. The upper plate 2 is in the form of a steel plate, and it is not easy to age and is stable in use under working conditions such as repeated rolling and high temperature. The present utility model fixes the lamp beads 4 at the bottom of the upper plate through the PU glue 5, and conducts the light emitted by the lamp beads 4 outward through the light-transmitting holes 3, so that when the sign is rolled, the rolling pressure and impact on the PU glue 5 and the lamp beads 4 can be reduced, and further improve the use stability of the PU glue 5 and the lamp beads 4.

[0028] In a preferred embodiment, for the structure of the present utility model, more specifically, anti-slip lines 6 are provided on the top surface of the upper plate 2. This can further improve the anti-slip property of the present utility model.

[0029] In a preferred embodiment, for the structure of the present utility model, more specifically, a receiving groove 7 is provided on the substrate 1 corresponding to the position of the light-emitting component. Through such a setting, the requirement for the thickness of the upper plate 2 can be reduced, and the layout space of the light-emitting component can be increased to facilitate the installation of the light-emitting component.

[0030] Or, in an alternative embodiment, a receiving groove for installing the light-emitting component can also be provided on the bottom surface of the upper plate 2.

[0031] In a preferred embodiment, for the structure of the present utility model, more specifically, the light-emitting component further includes a positioning groove 8. The notch of the positioning groove 8 is connected to the bottom surface of the upper plate 2. The positioning groove 8 and the upper plate 2 enclose a space for accommodating the lamp beads 4, and the lamp beads 4 are connected in the positioning groove 8.

[0032] As shown in the figure, by providing the positioning groove 8, after installing the lamp beads 4 on the upper plate 2, the installation stability of the lamp beads 4 on the upper plate 2 can be further improved through the positioning groove 8. Moreover, during assembly, the lamp beads 4 can be pre-installed at the positions corresponding to the lamp holes in the positioning groove 8, and then when the positioning groove 8 is integrally installed on the upper plate 2, the lamp beads 4 are automatically aligned with the light-transmitting holes 3. Compared with fixedly installing the lamp beads 4 on the larger-sized and heavier upper plate 2, this can facilitate the positioning installation of the lamp beads 4 and facilitate the positioning of the lamp beads 4 and the light-transmitting holes 3.

[0033] Preferably, the lamp beads 4 can be pre-bonded in the positioning groove 8.

[0034] For the connection between the positioning groove 8 and the upper plate 2, preferably, spot welding is used between the upper plate 2 and the positioning groove 8.

[0035] In a preferred embodiment, for the structure of the present utility model, more specifically, the groove wall of the positioning groove 8 is provided with a hollow structure. By setting the groove wall of the positioning groove 8 as hollow, during processing and manufacturing, the lamp beads 4 can be pre-fixed in the positioning groove 8 by means of bonding or clamping, etc. Then, the positioning groove 8 is connected to the upper plate 2, and then the PU glue 5 enters the positioning groove 8 through the light-transmitting holes 3 or the hollow groove wall of the positioning groove 8, so that the lamp beads 4 are filled, bonded and fixed in the positioning groove 8 by the PU glue 5. The groove wall of the positioning groove 8 being set as hollow can facilitate the full flow of the PU glue 5 into the positioning groove 8 and reduce internal air pockets.

[0036] In the illustrated embodiment, for the setting of the hollow structure, more specifically, as shown in the figure, the bottom wall and the side wall of the positioning groove 8 are provided with hollow holes at intervals.

[0037] In a preferred embodiment, for the structure of the present utility model, more specifically, the positioning groove 8 is set as a metal positioning groove 8, and there is a gap between the outer surface of the metal positioning groove 8 and the inner surface of the accommodating groove 7.

[0038] By setting a gap between the positioning groove 8 and the accommodating groove 7, the difficulty of the positioning groove 8 entering the accommodating groove 7 can be reduced, and when the upper plate 2 transmits vibration to the positioning groove 8, it can prevent the repeated shearing of the positioning groove 8 and the substrate 1 caused by the contact between the positioning groove 8 and the substrate 1, thereby preventing the connection failure between the positioning groove 8 and the upper plate 2 and between the PU glue 5 and the upper plate 2 caused by this.

[0039] In a preferred embodiment, for the structure of the present utility model, more specifically, the edge of the upper plate 2 forms a reinforcing rib 9 inserted into the accommodating groove 7, and the reinforcing rib 9 abuts against the outer side wall of the accommodating groove.

[0040] By setting the reinforcing rib 9, the shape stability of the edge of the upper plate 2 can be increased, and the reinforcing rib 9 can be inserted into the accommodating groove 7 to improve the cooperation stability between the upper plate 2 and the substrate 1.

[0041] In a preferred embodiment, for the structure of the present utility model, more specifically, the edge of the upper plate 2 is turned downwards to form the reinforcing rib 9.

[0042] In a preferred embodiment, for the structure of the present utility model, more specifically, the edge of the upper plate 2 is welded to the substrate 1. As shown in the figure, the upper plate 2 and the substrate 1 can be stably connected in this way.

[0043] In a preferred embodiment, with respect to the structure of the present utility model, more specifically, the PU glue 5 forms an upper covering layer 10 extending along the set path on the top surface of the upper plate 2. As shown in the figure, by providing the upper covering layer 10, the connection stability between the lamp beads 4 and the upper plate 2 can be further increased, and a continuous upper covering layer 10 can be formed on the upper side of the upper plate 2. Subsequently, the light transmitted from each lamp bead 4 to the upper covering layer 10 can form continuous marks after refraction and reflection inside, further enhancing the augmented reality effect.

[0044] It should be noted that the improvement of the present utility model lies in the installation structure of the sign, and there is no restriction or improvement on the installation method of the substrate 1 on the road surface. In an alternative embodiment, the substrate 1 can be integrally cast into the concrete layer of the road surface or fixed to the ground by rivets. Regarding the way of leading out the wires of the lamp beads 4, in a specific implementation, the wires can be led out from the positioning groove 8 and then led out to the side of the substrate 1 from the accommodating groove 7 of the substrate 1. Specifically, a lead-out groove can be cut out on the substrate 1, and the wires can be led out from the lead-out groove of the substrate 1.

[0045] Regarding the setting of the substrate 1, in the illustrated embodiment, the substrate 1 is set as a double-layer substrate 1, and the double-layer substrate 1 is connected by support ribs. A layout space for the positioning groove 8 is formed between the double-layer substrate 1 for convenient installation. In an alternative embodiment, the substrate 1 can also be set as a single-layer substrate 1, and the accommodating groove 7 is directly opened on the single-layer substrate 1.

[0046] Each embodiment in this specification is described in a progressive manner. For the same or similar parts between the embodiments, reference can be made to each other. Each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and reference can be made to the relevant parts of the method embodiment for the relevant content.
