If the specific posture changes, the directional indications will also change accordingly.

[0034] In addition, in the present utility model, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0035] In the present utility model, unless otherwise clearly specified and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; "connection" can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0036] See Figures 1-6 , the present utility model provides a vehicle-mounted mobile sign, which includes: a square active display panel 10 and a bracket 20.

[0038] Those skilled in the art should understand that this application mainly designs its vehicle-mounted and support structures based on existing active light-emitting signs to fix the light-emitting signs, and does not design the light-emitting signs themselves. As long as it is a panel-shaped light-emitting sign in the prior art, the technical solutions of this application can be applied.

[0039] In one embodiment, an integrated acoustic, optical, and electric control box 11 can be provided at the lower part of the display panel 10. The acoustic, optical, and electric control box 11 can be electrically connected to the display panel 10 by means of interface plugging, or can be integrated with the display panel 10.

[0040] Specifically, in a preferred design, the acoustic, optical, and electric control box 11 integrates red and blue flashing, a voice system, and a ternary lithium battery. The voice system is assisted by a 15W brand high-quality speaker + front and rear acoustic cavities, and the effect is comparable to that of a 30W sound column; the ternary lithium battery + M10 photovoltaic cell + charge and discharge protection management circuit small program can remotely replace the voice content for timed playback, playback when people come, etc. with additional dual outputs. One output can be independently output to supply power to the signboard, and one output is reserved for external devices to supply power. Customizable voices are supported, and remote mobile phone APP voice sending is supported. The APP has built-in TTS text-to-speech.
