Technical Field

[0001] The invention relates to the technical field of speed bump energy harvesting, and more particularly to a triangular modular speed bump energy harvesting device. Background Art

[0002] In daily life, vehicle speed bumps are very common, especially in places with dense traffic and frequent accidents, as well as parking lot entrances and exits. In these places, speed bumps are often needed to slow down vehicles passively, attracting the attention of drivers to protect driving safety or other purposes. During the deceleration process, the mechanical energy of the vehicle is relatively greatly lost. Speed ​​bump energy harvesting devices can be used to collect this energy and store it in the form of electrical energy.

[0003] At present, most of the research on such devices is still in the stage of theoretical analysis and circuit design. In actual situations, there are still many unresolved issues in speed bump energy collection, and experiments are needed to obtain the reasonable installation location and layout of the collection device. In addition, most of the speed bump energy collection devices designed previously have problems such as low energy recovery efficiency and short service life.

[0004] As mentioned above, designing a speed bump energy harvesting device that is flexible, adjustable, and easy to repair and replace is an issue that needs to be addressed urgently. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0032] The following will be combined Figure 1-3 It is worth noting that the following embodiments are only used to explain the present application and do not constitute a limitation on the present application.

[0033] Example

[0034] like Figure 1As shown, a triangular modular speed bump energy harvesting device provided by an embodiment of the present invention includes: a lower support base 1; a side support steel plate 2; a structural frame 3; a triangular plate 4; a small generator 5; and a transmission gear 6 connected to a transmission shaft. The function of the transmission gear 6 is to be able to extend to a generator at a distance by installing a transmission system through the part. Among them, the lower support base, the side support steel plate, and the structural frame are fixed on the ground, and the triangular plate is installed on the lower support base through a spring connection.

[0035] When a vehicle passes through the device, the spring corresponding to the module under pressure is compressed, and the triangular plate is displaced in the direction of spring compression. Finally, the side of the triangular plate contacts the side of the hexagonal beam to form a limit, and the triangular plate stops displacing until the vehicle passes the corresponding module, the spring returns to its original length, and the triangular plate is reset.

[0036] like Figure 2 , 3 As shown, each triangular module corresponds to a set of transmission gears and a one-way energy collection device. When the triangular plate is pressed down, the rack fixedly connected to the triangular plate causes the gear to drive the one-way energy collection device to rotate counterclockwise, and the two movable teeth in the one-way energy collection device open, driving the transmission shaft to rotate. When the triangular plate is reset and moved upward, the rack causes the gear to drive the one-way energy collection device to rotate clockwise, and the two movable teeth in the one-way energy collection device are retracted and cannot drive the transmission shaft to rotate, thereby realizing one-way energy collection. Figure 4 , 5 6 are schematic diagrams of the components of the unidirectional energy collection device. Figure 2 As shown in the figure, the first gear 9 is fixed to the mounting plate 11, and the annular collecting body 10 is fixed to the transmission shaft 14. When the surface triangular plate structure is subjected to pressure, the second gear 8 is driven to rotate clockwise, and the first gear 9 and the mounting plate 11 are rotated counterclockwise, thereby driving the annular collecting body 10 to rotate counterclockwise, and the transmission shaft 14 is rotated counterclockwise at the same time.

[0037] like Figure 7 , 8 As shown, the energy harvesting device consists of two layout structures, A and B. Fig. 9 In the two layout structures A and B, the fixed positions of the rack and the triangular plate are different, so the same group of triangular kinetic energy collection modules can be connected to the same fixed shaft and transmission shaft and do not affect each other during operation, so that the fixed shaft 13 is always the shaft that rotates in the same direction and is connected to the generator, and the transmission shaft 14 is always the shaft that fixes the position of the transmission gear.

[0038] like Fig.10 The outer frame is composed of regular hexagonal components, and the side contacting the upper triangular plate structure is 60° to the horizontal plane. The side of the upper plate structure is also 60° to the horizontal plane, thus forming a natural limit structure and giving the interior a larger space.

[0039] like Fig.11 The side structure of the slopes on both sides of the speed bump is reduced to a single-row collection layout due to insufficient space. Only a row of triangular plates close to the top of the speed bump is equipped with springs and corresponding energy collection devices. The lower end of the spring of the corresponding energy collection module is fixed on the side of the lower support base, such as Fig.11 As shown in , the triangular plate structure in the side structure remains parallel to the side slope of the base, thereby avoiding damage caused by eccentric force on the spring. The remaining plates close to the ground in the side structure are not equipped with springs, that is, this row of triangular plates does not participate in kinetic energy collection and is directly fixed to the frame structure.

[0040] The triangular modular speed bump energy harvesting device provided in the embodiment of the present invention comprises the following assembly steps:

[0041] S1: Select a spring with a suitable stiffness coefficient according to the actual application scenario;

[0042] S2: Install the spring at the corresponding position of the lower support base;

[0043] S3: Install the external frame structure and the side support steel plate on one side;

[0044] S4: Install the fixed shaft and the transmission shaft;

[0045] S5: Install the transmission gear and the unidirectional energy collection device in groups on the fixed shaft and the transmission shaft.

[0046] Location;

[0047] S6: Install the side support steel plate on the other side;

[0048] S7: Connect and fix the triangular plate to the rack;

[0049] S8: Adjust the specific positions of the transmission gear and the one-way energy collection device, and install the corresponding position of the lower end of the triangular plate on the upper end of the spring.

[0050] As described above, the triangular modular speed bump energy harvesting device of the embodiment of the present invention can flexibly install different springs according to the actual application scenario to achieve efficient energy harvesting. The modular design makes installation and subsequent maintenance more convenient and has stronger practical value. In addition, the external frame structure of the device makes the entire device more stable and effectively extends the service life of the device. In addition, in addition to being able to effectively harvest energy, the device can also effectively produce a certain shock-absorbing effect on vehicles passing through the speed bump, making it more practical.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
