The nighttime power supply unit converts solar energy into electrical energy and stores it, outputting electrical energy at night to drive the swing arm mechanism. This solar-powered circulating power supply system allows the swing arm mechanism to be continuously powered by solar-generated electricity during both day and night, eliminating concerns about the swing arm mechanism ceasing operation after sunset, effectively improving the power supply shortcomings of current electric swing arm machines.

Description

[Technical Field]

[0001] This invention relates to a transmission device and a power supply system, and more particularly to a solar-powered circulating power transmission device and its solar-powered circulating power supply system. [Previous Technology]

[0002] During road construction, to prevent vehicles or pedestrians from encroaching on the construction area and causing accidental injuries to road users and construction workers, traffic controllers are usually stationed in the oncoming traffic direction of the construction area. These controllers use flags to instruct road users to detour. However, in very hot weather, traffic controllers are prone to feeling unwell or suffering from heatstroke. In view of this, more and more construction companies have switched to using electric swing-arm machines to replace manual labor, with electric power driving the electric swing-arm machines to automatically wave flags for warning.

[0003] Because electricity is not readily available during outdoor construction, these types of electric swing-arm machines are equipped with solar modules. During the day, the solar modules power the machine. However, after sunset, the solar modules stop generating electricity, so the electric swing-arm machine typically stops operating shortly after sunset. Therefore, the current power supply system for electric swing-arm machines still needs improvement. [Summary of the Invention]

[0004] Therefore, the object of the present invention is to provide a solar cycle power supply system that can improve at least one of the disadvantages of the prior art.

[0005] Therefore, the solar-powered circulating power supply system of the present invention is suitable for powering a load. The solar-powered circulating power supply system includes a first solar module and a second solar module capable of converting solar energy into electrical energy, a first battery and a second battery, and a control device electrically connected to the load. The control device is electrically connected between the first solar module and the first battery, and electrically connected between the second solar module and the second battery.

[0006] The control device includes a power generation status determination module and a power supply control module. The power generation status determination module generates a first signal when the electrical energy generated by the first solar module and / or the second solar module exceeds a first threshold. The power supply control module is triggered by the first signal and controls the first solar module and the second solar module to charge the first battery and the second battery respectively with the generated electrical energy, and outputs the electrical energy stored in the first battery to drive the load. The power generation status determination module generates a second signal when the electrical energy generated by the first solar module and / or the second solar module falls below a second threshold. The power supply control module is triggered by the second signal and outputs the electrical energy stored in the second battery to drive the load.

[0007] A solar-powered circulating power supply system is suitable for powering a load. The solar-powered circulating power supply system includes a daytime power supply device and a nighttime power supply device for electrically connecting to the load.

[0008] The daytime power supply device includes a first solar module for converting solar energy into electrical energy, a first battery, and a first control module electrically connected between the first solar module and the first battery. The first control module includes a first power generation status determination unit and a first power supply control unit.

[0009] When the first power generation state determination unit determines that the electrical energy generated by the first solar module is higher than a first threshold, it will trigger the first power supply control unit, which will charge the first battery with the electrical energy generated by the first solar module and output the electrical energy stored in the first battery to drive the load.

[0010] The nighttime power supply device is signal-connected to the daytime power supply device. The nighttime power supply device includes a second solar module for converting solar energy into electrical energy, a second battery, and a second control module electrically connected between the second solar module and the second battery.

[0011] The second control module includes a second power generation state determination unit and a second power supply control unit. When the second power generation state determination unit determines that the electrical energy generated by the second solar module is higher than the first threshold, it triggers the second power supply control unit, which then charges the second battery with the electrical energy generated by the second solar module and does not output the electrical energy stored in the second battery. When the second power generation state determination unit determines that the electrical energy generated by the second solar module is lower than a second threshold, it triggers the second power supply control unit, which then outputs the electrical energy stored in the second battery to drive the load and controls the first power supply control unit not to output the electrical energy stored in the first battery.

[0012] Therefore, another object of the present invention is to provide a solar-powered circulating transmission device that can improve at least one of the disadvantages of the prior art.

[0013] Therefore, the solar-powered circulating power transmission device of the present invention includes a swing arm mechanism and a solar-powered circulating power system as described above.

[0014] The swing arm mechanism includes a bracket, a geared motor mounted on the bracket, and a swing arm module pivotally mounted on the bracket and connected to the geared motor. The geared motor can be electrically driven to drive the swing arm module to reciprocate relative to the bracket. The solar-powered circulating power supply system is electrically connected to the geared motor and can output the electrical energy stored in the first battery or the second battery to drive the geared motor.

[0015] The advantage of this invention is that, through the design of the solar energy cycle power supply system, the power generated by solar energy conversion can be continuously used to drive the swing arm mechanism or the load connected by electricity during the day and at night, without worrying that the swing arm mechanism will stop operating after sunset. This can indeed improve the power supply shortcomings of the current electric swing arm machine.

Implementation Method

[0017] Before the present invention is described in detail, it should be noted that similar elements are represented by the same numbers in the following description.

[0018] Referring to Figures 1, 2 and 3, a first embodiment of the solar-powered circulating transmission device of the present invention includes a swing arm mechanism 2 and a solar-powered circulating system 6 electrically connected to the swing arm mechanism 2.

[0019] The swing arm mechanism 2 includes a support 3 for erecting on the ground, a reduction motor device 4 mounted on the support 3, and a swing arm module 5 pivotally mounted on the support 3 and connected to the reduction motor device 4.

[0020] The bracket 3 has a base 31, a wheel set 32 ​​mounted on the base 31, a support module 33 that can be extended and retracted on the base 31, a top seat 34 mounted on the top of the support module 33, and a model head 35 disposed on the top seat 34.

[0021] The base 31 has a plate-shaped body portion 311 extending front to back for laying on the ground, and a lifting grip portion 312 extending obliquely upward from the front end of the plate body portion 311. The lifting grip portion 312 is provided with a gripping hole 313. The wheel set 32 ​​is pivotally mounted on the rear end section of the plate body portion 311.

[0022] The support module 33 has two lower support rods 331 that are spaced apart from each other and are erected on the plate body 311, two upper support rods 333 that are retractable and inserted into the lower support rods 331 respectively, and two positioning members 335 that are respectively disposed on the lower support rods 331 and the upper support rods 333.

[0023] In this first embodiment, each lower support rod 331 has a plurality of vertically arranged positioning holes 332, and each upper support rod 333 has a plurality of vertically arranged positioning holes 334. Each upper support rod 333 can be adjusted vertically relative to the corresponding lower support rod 331, so that one of the positioning holes 334 communicates with one of the positioning holes 332. Each positioning member 335 is a positioning pin, which can be detachably inserted into the correspondingly connected positioning holes 332, 334, so that the corresponding lower support rod 331 and upper support rod 333 can be adjusted vertically for positioning.

[0024] Since the height of the support module 33 can be adjusted by extension and retraction, which is an existing technology and there are many types, the implementation is not limited to the above-mentioned implementation mode.

[0025] The top seat 34 is located at the top of the upper support rod 333 and can be driven by the support module 33 to move the model head 35 and the reduction motor device 4 up and down.

[0026] The geared motor device 4 includes a geared motor module 41 mounted and fixed on the top seat 34 and having an output shaft 410 with a front-rear axial direction, and an eccentric member 42 connected to the output shaft 410 of the geared motor module 41. The eccentric member 42 has an eccentric end 421 that is eccentrically disposed relative to the output shaft 410.

[0027] The swing arm module 5 includes a swing seat 51 pivotally mounted on the top seat 34, two swing arms 52 spaced apart on the swing seat 51, and a transmission link 53 pivotally connected between the eccentric member 42 and the swing seat 51. The swing seat 51 has a pivot portion 511 pivotally connected to the top seat 34 and an eccentric portion 512 offset from the pivot portion 511. The swing arms 52 are respectively mounted on the left and right sides of the pivot portion 511 of the swing seat 51. The transmission link 53 is pivotally connected at both ends to the eccentric end 421 and the eccentric portion 512, respectively.

[0028] When the geared motor module 41 is driven to operate, the output shaft 410 drives the eccentric member 42 to rotate relative to the top seat 34. The eccentric member 42 drives the rocker seat 51 to reciprocate up and down relative to the left and right ends of the top seat 34 via the transmission link 53, thereby driving the rocker arms 52 to swing up and down. In practice, warning flags or luminous warning sticks can be set on the rocker arms 52 to produce a warning effect.

[0029] The solar-powered circulating power supply system 6 includes a first solar module 61, a second solar module 62, a first battery 63, a second battery 64, and a control device 65. The control device 65 is electrically connected between the first solar module 61, the second solar module 62, the first battery 63, and the second battery 64, and is also electrically connected to the geared motor module 41.

[0030] The first solar module 61 and the second solar module 62 are mounted on the top base 34 and are located on the left and right sides of the model head 35, respectively. The first solar module 61 and the second solar module 62 can be used to convert solar energy into electrical energy. The first battery 63 and the second battery 64 are both mounted on the base 31 and can be used to store electricity, and the stored electrical energy can be controlled to be output. The first battery 63 and the second battery 64 are, for example, but not limited to, storage batteries, lithium-ion batteries, etc.

[0031] Since the first solar module 61 and the second solar module 62, as well as the first battery 63 and the second battery 64, are of various types and are existing technologies, they will not be described in detail.

[0032] The control device 65 includes a power generation status judgment module 651 and a power supply control module 652.

[0033] The power generation status judgment module 651 receives and analyzes the amount of electrical energy generated by the first solar module 61 and the second solar module 62. It generates a first signal when it determines that the electrical energy generated by either the first solar module 61 or the second solar module 62 is greater than a first threshold, and generates a second signal when it determines that the electrical energy generated by either the first solar module 61 or the second solar module 62 is less than a second threshold. The first threshold is greater than the second threshold. The first threshold and the second threshold are, for example, but not limited to, voltage values.

[0034] The power supply control module 652 is triggered by the first signal to charge the first battery 63 with the electrical energy generated by the first solar module 61, and to charge the second battery 64 with the electrical energy generated by the second solar module 62. Furthermore, the power supply control module 652 also outputs the electrical energy stored in the first battery 63 to drive the geared motor module 41, but does not output the electrical energy stored in the second battery 64. The power supply control module 652 is triggered by the second signal to output the electrical energy stored in the second battery 64 to drive the geared motor module 41, and does not output the electrical energy stored in the first battery 63.

[0035] When the solar-powered circulating power transmission device of the present invention is used, a set of clothes can be put on the top seat 34 of the bracket 3 and the support module 33, for example, a reflective vest can be set, and warning flags or luminous warning sticks can be set on the swing arms 52 of the swing arm module 5 respectively, so as to simulate the appearance of waving flags to warn people.

[0036] During the day, the electrical energy generated by the first solar module 61 and the second solar module 62 exceeds the first threshold. The power supply control module 652 is triggered by the first signal generated by the power generation status judgment module 651, and the electrical energy generated by the first solar module 61 and the second solar module 62 charges the first battery 63 and the second battery 64 respectively. At the same time, the power supply control module 652 also outputs the electrical energy stored in the first battery 63 to drive the geared motor module 41. The geared motor module 41 drives the swing arm module 5 to swing back and forth via the eccentric member 42, thereby waving the warning flags or luminous warning sticks set up by the swing arms 52.

[0037] As sunset approaches evening, the electrical energy generated by the first solar module 61 and the second solar module 62 will gradually decrease. When the electrical energy generated by one of the first solar module 61 and the second solar module 62 has decreased below the second threshold, the power generation status judgment module 651 will generate the second signal. The power supply control module 652 will be triggered by the second signal and will stop outputting electrical energy from the first battery 63 and instead output electrical energy from the second battery 64 to drive the geared motor module 41, thereby driving the swing arms 52 to continue waving the warning flag or the luminous warning stick.

[0038] As the sunlight gradually intensifies after sunrise, the electrical energy generated by the first solar module 61 and the second solar module 62 will gradually increase. When the electrical energy generated by one of the first solar module 61 and the second solar module 62 rises above the first threshold, the power generation status judgment module 651 will generate the first signal. The power supply control module 652 will be triggered again by the first signal, and in addition to charging the first battery 63 and the second battery 64 respectively by the first solar module 61 and the second solar module 62, it will also switch to outputting the electrical energy of the first battery 63 to drive the geared motor module 41, and will no longer output the electrical energy of the second battery 64.

[0039] Through the design of this solar-powered circulating power supply system 6, during the daytime hours of sunrise, the first battery 63 can supply power to drive the swing arm mechanism 2, while the second battery 64 continuously stores power. During the nighttime hours of sunset, the second battery 64 supplies power to drive the swing arm mechanism 2. In other words, the solar-powered circulating power supply system 6 can continuously supply power to drive the swing arm mechanism 2 for warning purposes, whether it is day or night.

[0040] When moving the solar-powered circulating transmission device, the base 31 can be lifted by pulling the lifting grip 312 upwards, causing the base 31 to swing upwards off the ground with the wheel set 32 ​​as the fulcrum, so that the bracket 3 only rolls against the ground with the wheel set 32. At this time, the base 31 can be moved by pushing and pulling it back and forth, which is quite convenient.

[0041] In practice, the above-mentioned power judgment and charging / discharging control functions of the control device 65 can be achieved through the design of electronic circuits, logic circuits, and / or microprocessors.

[0042] Referring to Figure 4, a second embodiment of the solar-powered circulating power transmission device of the present invention differs from the first embodiment in that the design of the solar-powered circulating power system 6 is different. For ease of explanation, the following description will only focus on the differences between these embodiments.

[0043] In this second embodiment, the solar-powered circulating power supply system 6 includes a daytime power supply device 7 and a nighttime power supply device 8.

[0044] The daytime power supply device 7 includes a first solar module 71 and a first battery 72, and a first control module 73 electrically connected to the first solar module 71 and the first battery 72. The first control module 73 has a first power generation status determination unit 731 and a first power supply control unit 732.

[0045] The nighttime power supply device 8 includes a second solar module 81 and a second battery 82, and a second control module 83 electrically connected to the second solar module 81 and the second battery 82, and the second control module 83 is also signal-connected to the first control module 73. The second control module 83 has a second power generation status determination unit 831 and a second power supply control unit 832.

[0046] When the first power generation state judgment unit 731 determines that the electrical energy generated by the first solar module 71 is higher than a first threshold, the first power supply control unit 732 will be triggered by the first power generation state judgment unit 731, and the electrical energy generated by the first solar module 71 will be used to charge the first battery 72, and the electrical energy stored in the first battery 72 will be output to drive the swing arm mechanism 2.

[0047] When the second power generation state judgment unit 831 determines that the electrical energy generated by the second solar module 81 is higher than the first threshold, the second power supply control unit 832 will be triggered by the second power generation state judgment unit 831, and the electrical energy generated by the second solar module 81 will be used to charge the second battery 82, and the stored electrical energy of the second battery 82 will not be output.

[0048] When the second power generation state judgment unit 831 determines that the electrical energy generated by the second solar module 81 is lower than a second threshold, the second power supply control unit 832 will be triggered by the second power generation state judgment unit 831, and output the electrical energy stored in the second battery 82 to drive the swing arm mechanism 2, and will control the first power supply control unit 732 not to output the electrical energy stored in the first battery 72.

[0049] In use of this second embodiment, during the daytime, the first control module 73 of the daytime power supply device 7 continuously charges the first battery 72 with the electrical energy generated by the first solar module 71, and continuously outputs electrical energy from the first battery 72 to drive the swing arm mechanism 2. Furthermore, the second control module 83 of the nighttime power supply device 8 continuously charges the second battery 82 with the electrical energy generated by the second solar module 81, but does not output the stored electrical energy from the second battery 82.

[0050] After sunset, the second control module 83 of the nighttime power supply device 8 will control the first control module 73 to stop outputting power from the first battery 72, and the second control module 83 will output the stored power from the second battery 82 to drive the swing arm mechanism 2. With this design, the swing arm mechanism 2 can be continuously driven to operate during both day and night.

[0051] In practice, the above-mentioned power judgment and charging / discharging control functions of the daytime power supply device 7 and the nighttime power supply device 8 can be achieved through the design of electronic circuits, logic circuits, and / or microprocessors.

[0052] In the above two embodiments, the solar circulating power supply system 6 can also be used to supply the electrical energy required for the operation of other loads.

[0053] In summary, through the design of the solar power circulation system 6, the power generated by solar energy conversion can be continuously used to drive the swing arm mechanism 2 or the electrically connected load during the day and night, without worrying that the swing arm mechanism 2 will stop operating after sunset. This can indeed improve the power supply shortcomings of the current electric swing arm machine.

[0054] Furthermore, by using the geared motor device 4 to drive the swing of the rocker seat 51, energy consumption can be reduced and the output torque can be increased, thereby driving the swing of the rocker seat 51 and the swing arms 52 to swing more efficiently.

[0055] Therefore, the solar-powered circulating power transmission device of the present invention is indeed a highly innovative and practical creation, and can indeed achieve the purpose of the present invention.

[0056] However, the above description is only an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the patent specification of the present invention shall still fall within the scope of the patent of the present invention.
