The housing 100 is made of stainless steel, and an inner space 110 for accommodating other components is formed therein, thereby protecting the other components. A through hole 120 capable of communicating with the inner space 110 is formed at the top of the housing 100, and the force bearing rod 200 can pass through the through hole 120 and be connected with the housing 100 in a sliding manner. One end of the bearing rod 200 is connected with the shell 100 through the first elastic piece 300, and the other end of the bearing rod 200 is connected with the contact assembly 400, so that when the contact assembly 400 is pressed, the bearing rod 200 can transmit the acting force, and the first elastic piece 300 mainly plays a role in resetting the bearing rod 200 and reducing the impact of the bearing rod 200 on the shell 100. In this embodiment, the first elastic member 300 is embodied as a spring, and the compression direction thereof is the same as the shape direction of the force bearing rod 200.

The force-bearing rod 200 is provided with a press block 210 having an annular shape. A plurality of L-shaped beams 500 are arranged in a circumferential array around the carrier rod 200, one end of each L-shaped beam 500 is fixedly connected with the shell 100, and the other end thereof is suspended and can be contacted with the pressing block 210. Each L-beam 500 is mounted with a piezoelectric film 600 for converting the mechanical energy of deformation of the L-beam 500 into electrical energy. When the bearing rod 200 is pressed to longitudinally displace, the pressing blocks 210 can contact and apply pressure to each L-shaped beam 500, so that the L-shaped beams 500 are pressed and deformed, the piezoelectric film 600 generates electricity, and the conversion of electric energy is completed.

All the L-beams 500 and the piezoelectric film 600 thereon, which are distributed in a circumferential array at the same height, are set as one power generation group.

Each piezoelectric film 600 is electrically connected to an energy storage (not shown) through a wire, so that the electric energy generated by each piezoelectric film 600 is collected into the energy storage for storage, and when an external road auxiliary system needs to be supplied with electric energy, the electric energy can be directly obtained from the energy storage. Specifically, the lead adopts an anti-corrosion waterproof lead, so that the abrasion or aging of the lead in the long-term use process is reduced, and the service life of the pavement pressing type energy collecting device is prolonged.

For the contact assembly 400, which comprises a pressure plate 410, a second elastic member 420 and a contact plate 430, the pressure plate 410 is fixedly connected with the force bearing rod 200 and is used for increasing the contact area of the force bearing rod 200 and a vehicle tire and reducing the pressure generated when the force bearing rod 200 and the vehicle tire are contacted. The second elastic member 420 is embodied as a spring, both ends of which are respectively connected to the pressing plate 410 and the contact plate 430, and the contact plate 430 is in direct contact with the vehicle tire, so that the instantaneous impact force generated when the contact is made can be absorbed by the second elastic member 420, thereby reducing the damage to the force bearing rod 200. Specifically, the touch panel 430 has a reflective strip attached to its surface, which reflects light when illuminated, thereby alerting a driver or a pedestrian. It will be readily understood that it is also possible to replace the LED lighting strip with an electrical connection to the energy store, so that the electrical energy required for self-illumination can be taken from the energy store.

The housing 100 is a main structure of the road surface pressing type energy collecting device, and is specifically a stainless steel member for loading and protecting other components. The housing 100 is cylindrical and is buried underground to absorb road vibration energy. The housing 100 has an inner space 110 capable of accommodating other components therein, and a through hole 120 communicating with the inner space 110 is formed at the top of the housing 100, and the through hole 120 is formed at the center of the top of the housing 100.

The bearing rod 200 is in a round rod shape and can penetrate through the through hole 120, and the through hole 120 is matched with the shape of the bearing rod 200, so that the lateral movement of the bearing rod 200 after penetrating through the through hole 120 is reduced. The force bearing rod 200 is superposed with the central axis of the shell 100. The force bearing rod 200 is provided with a press block 210 for transmitting pressure, which is annular.

The first elastic member 300 is specifically a spring, and both ends of the spring are respectively connected to one end of the force-bearing rod 200 and the housing 100, and are in a compressed state, so as to restore the force-bearing rod 200 and reduce the impact of the force-bearing rod 200 on the housing 100.

The contact assembly 400 is arranged at the other end of the bearing rod 200 and is used for contacting with a vehicle tire, and the contact assembly plays a role in increasing the contact area of the bearing rod 200 and the vehicle tire.

The number of the L-shaped beams 500 is multiple, and the L-shaped beams are distributed around the circumference of the bearing rod 200 in an array manner. One end of the L-shaped beam 500 is fixedly connected to the housing 100, and the other end is suspended and can contact the pressing block 210. The number of piezoelectric membranes 600 corresponds to the number of L-beams 500 and is arranged in one-to-one correspondence with the L-beams 500. The piezoelectric film 600 is attached to the L-shaped beam 500, so that when the L-shaped beam 500 is pressed by the pressing block 210 to be deformed, the piezoelectric film 600 is deformed, and mechanical energy is converted into electric energy through a positive piezoelectric effect. The piezoelectric element is electrically polarized under the action of external mechanical force, and bound charges with opposite signs appear on the surfaces of two ends of the piezoelectric element, and the charge density is in direct proportion to the external mechanical force. The piezoelectric film 600 for generating current by using the direct piezoelectric effect is a prior art and will not be described herein.

The energy storage is electrically connected with each piezoelectric film 600 through a lead, and the electric energy generated by the piezoelectric films 600 is transmitted to the energy storage through the lead for storage, and can be obtained from the energy storage when external equipment needs to use the electric energy. An energy storage is in this application referred to as a device or means capable of storing electrical energy.

Furthermore, the L-shaped beams 500 distributed in a circumferential array at the same height and the piezoelectric film 600 thereon are a power generation set, the number of the pressing blocks 210 is at least two, the pressing blocks 210 are arranged along the shape direction of the force bearing rod 200, the number of the power generation sets is consistent with the number of the pressing blocks 210 and the pressing blocks 210 are arranged in a one-to-one correspondence manner, when the force bearing rod 200 is pressed to move, each pressing block 210 presses the corresponding L-shaped beam 500, so that the electric energy converted by single pressing is increased, and the conversion rate is improved.

Further, the contact assembly 400 includes a pressing plate 410, a second elastic member 420, and a contact plate 430. The pressure plate 410 is fixedly connected with the bearing rod 200 and is used for increasing the contact area of the bearing rod 200 and a vehicle tire and reducing the pressure generated when the bearing rod 200 and the vehicle tire are in contact. The second elastic member 420 is embodied as a spring, both ends of which are respectively connected to the pressure plate 410 and the contact plate 430, and the contact plate 430 is used to directly contact the vehicle tire. When the vehicle is installed, the contact plate 430 is exposed out of the ground 700, and when the vehicle drives over and presses the contact plate 430, the second elastic element 420 is firstly compressed to absorb the instantaneous impact force when the vehicle rolls over, and then the pressure is transmitted to each L-shaped beam 500 through the pressure plate 410 and the force bearing rod 200 to realize mechanical energy conversion.

Furthermore, a reflective strip is attached to the contact plate 430 to reflect light when light is emitted, thereby providing a warning effect. It is easily understood that the reflective strip can also be replaced by an LED light-emitting strip which is powered by an energy storage device so as to emit light by itself and achieve a better warning effect.

Further, the road surface pressing type energy collecting device further comprises a sensor which is electrically connected with the energy storage device and used for detecting the traffic flow. Specifically, a touch sensor may be used, which is triggered when the vehicle passes through and presses the force bearing rod 200, and the traffic density at this time can be estimated by the number of times of triggering within a period of time. The visual sensor can also be adopted, and the traffic density information can be acquired by continuously shooting the road surface through the visual sensor arranged on the road surface.
