Embodiment Construction

[0017] The specific embodiment of the present invention and working process will be further described below in conjunction with accompanying drawing.

[0018] The orientation terms such as up, down, left, right, front and rear in this application document are established based on the positional relationship shown in the drawings. If the drawings are different, the corresponding positional relationship may also change accordingly, so this should not be understood as limiting the scope of protection.

[0019] The invention provides a speed bump power generation device, which can convert the pressure generated when a car passes through the speed bump into electric energy, and supply it to roadside power facilities, including station sign lighting, emergency mobile device charging or other electrical appliances.

[0020] Such as figure 1 As shown, the speed bump power generation device includes a piezoelectric power generation device and an energy storage device 4 . The piezoele...

Abstract

The invention discloses a speed bump power generation device, and the device comprises a piezoelectric power generation apparatus and an energy storage apparatus. The piezoelectric power generation apparatus comprises at least one piezoelectric power generation unit. The piezoelectric power generation unit comprises a speed bump, a pressure augmentor, a piezoelectric material, and a box body withan inner groove. The speed bump, the pressure augmentor and the piezoelectric material are sequentially placed in the box body from the top to the bottom. The piezoelectric material is connected withthe energy storage apparatus through a connecting line. The piezoelectric power generation apparatus comprises a plurality of piezoelectric power generation units which are sequentially connected to form a strip-shaped road speed bump. The piezoelectric materials of the piezoelectric power generation units are connected in parallel and / or in series through connecting lines. The device also comprises a boost circuit board, and the boost circuit board is disposed between the energy storage apparatus and the piezoelectric material. The device is simple in structure, and is high in stability of the quality of power generation.

Description

technical field [0001] The invention relates to a speed bump power generation device, which belongs to the technical field of piezoelectric power generation in the field of energy saving and environmental protection. Background technique [0002] The speed bump is a special protruding facility on the road. When the vehicle passes by, due to the severe mechanical vibration that may be generated, the driver will consciously reduce the speed to ensure road safety. And this mechanical vibration is often a kind of energy. Since the total length of roads in our country is long and the number of motor vehicles is huge, this is undoubtedly a potential energy source. Especially near the bus station, on the one hand, power is needed to provide lighting for the bus station’s signage to facilitate people’s travel. On the other hand, vehicles need to slow down when passing the bus station to ensure safety. [0003] Patent document CN204551316 (2015.08.12) proposed a self-generating spe...
