Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0035] In the description of the present application, it should be understood that the terms "opening", "upper", "middle", "length", "inner" and the like indicate the orientation or positional relationship, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the components or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0036] In order to keep the following description of the embodiments of the present application clear and concise, the present application omits the detailed description of known functions and known components.

[0037] Embodiment one

[0038] Please refer to Figures 1-5 As shown in the figure, in the present embodiment, a tunnel vehicle piezoelectric energy recovery indicating lamp is provided, a tunnel pavement 1 is laid in the tunnel, and then two road edge crash side stones 2 are fixedly installed on both sides of the tunnel pavement 1. These road edge crash side stones 2 not only play a role in protecting the edge of the tunnel, but also serve as the installation basis of the indicating lamp.

[0039] A first groove 3 is formed in each road edge crash side stone 2, and a connecting block 4 is installed in the groove. The connecting block 4 has a road edge indicating lamp 5 fixedly installed inside, which is used for lighting in the tunnel. At the same time, a piezoelectric power generation unit 6 is arranged in the tunnel pavement 1, which can generate electric energy through the pressure of the tire on the road when the vehicle passes. A battery 18 is arranged in the road edge crash side stone 2, and a second connecting wire 71 is electrically connected between the battery 18 and the road edge indicating lamp 5, and a first connecting wire 7 is electrically connected between the battery 18 and the piezoelectric power generation unit 6, so as to facilitate the storage of electric energy. The piezoelectric power generation unit 6 comprises a piezoelectric power generation device, which is composed of a plurality of piezoelectric energy harvesting units;

[0040] When the vehicle is running on the tunnel pavement 1, the tire exerts pressure on the tunnel pavement 1, which is transmitted to the piezoelectric power generation unit 6, exciting the internal piezoelectric energy harvesting unit to generate electric energy. The piezoelectric energy harvesting unit uses the piezoelectric effect to convert mechanical energy (pressure of the vehicle tire on the road) into electrical energy. The generated electric energy is transmitted to the storage battery 18 through the first connecting wire 7 for storage. When lighting is needed, the storage battery 18 transmits electric energy to the curb indicator light 5 through the second connecting wire 71, and the curb indicator light 5 emits light under the drive of electric energy to provide lighting for the tunnel.

[0041] In order to realize the quick fixing and dismounting of the connecting block 4 in the curb anti-collision curbstone 2, a set of connecting components is designed. Two second grooves 11 are formed in the connecting block 4, and two clamping blocks 10 are slidably installed in each groove. Four clamping grooves 9 are formed in the curb anti-collision curbstone 2 and communicate with the first grooves 3. During installation, the clamping blocks 10 are aligned with the clamping grooves 9 and pushed in until the clamping blocks 10 are completely clamped in the grooves, thereby fixing the connecting block 4. At the same time, two clamping springs 12 are installed between the two clamping blocks 10 to ensure that the clamping blocks 10 can remain clamped when not subjected to external force.

[0042] In order to facilitate the dismounting of the connecting block 4, an extrusion assembly is designed. Two third grooves 13 are formed in the connecting block 4, and a pressing plate 14 is slidably installed in each groove. The side end of the pressing plate 14 is fixed with two extrusion rods 16, and an extrusion groove 8 is formed in the clamping block 10. When it is necessary to dismount the connecting block 4, the extrusion rods 16 are brought into contact with the inclined surface of the extrusion groove 8 and generate extrusion force by pressing the pressing plate 14, thereby pushing the clamping block 10 to move outward and disengage from the clamping groove 9, achieving quick dismounting of the connecting block 4.

[0043] The third groove 13 and the recessed groove 17 form an L-shaped groove, which facilitates the maintenance personnel to pull the connecting block 4 outward by inserting their fingers into the L-shaped groove.

[0044] Example Two

[0045] Based on the improvement of Example One: refer to the attached Figure 1 -Attached Figure 5 A tunnel vehicle piezoelectric energy recovery indicator light is provided to ensure that the pressing plate 14 can automatically reset when not subjected to external force. Positioning springs 15 are fixed to the side ends of the two pressing plates 14, and the positioning springs 15 are fixed in the third grooves 13. In addition, two recessed grooves 17 are formed in the connecting block 4 and communicate with the third grooves 13, so as to facilitate the insertion of fingers into the pressing plate 14 and the operation of the pressing plate 14.

[0046] In order to improve the convenience of operation, the two pressing plates 14 are designed to be horizontal with the side ends of the connecting block 4, so that the user can directly press from the side without the need for special tools to achieve quick dismounting of the connecting block 4.
