Technical Field
[0001] This utility model relates to the technical field of bicycles, and in particular to a dual-power bicycle seat cooling device without a power source. Background Technology
[0002] With the acceleration of global climate change and urbanization, bicycles, as an environmentally friendly and healthy mode of transportation, are becoming increasingly popular. However, in the hot summer, prolonged cycling can cause the bicycle saddle to heat up, leading to discomfort for the rider. To address this issue, various cooling methods have been explored, such as using breathable saddle materials and installing water-cooling systems. However, these methods are either limited in effectiveness or costly and not easily adopted.
[0003] As a clean and renewable energy source, solar energy has been increasingly widely used in various fields in recent years. Using solar energy to cool bicycle saddles can not only effectively reduce saddle temperature and improve riding comfort, but also reduce dependence on traditional energy sources, which is in line with the concept of sustainable development.
[0004] In current technology, the widespread use of solar panels allows solar energy to be effectively converted into electrical energy to power various devices. In the bicycle industry, there are already cases of using solar energy to power bicycle lights, GPS navigation, and other devices. For example, some designs install small solar panels under the seat to drive miniature fans, thereby achieving a cooling effect.
[0005] In addition to solar energy, human power is another available energy source. Some bicycles are designed with human-powered generators that produce electricity through the rider's pedaling motion to power electronic devices such as lights and speakers. This human-powered cooling system can be combined with solar energy systems to improve energy efficiency.
[0006] However, no technicians have yet combined the two technologies, so how to combine the two technologies has become a technical problem that urgently needs to be solved. Utility Model Content
[0007] The purpose of this invention is to provide a dual-power bicycle seat cooling device without a physical power source, in order to solve the problem that existing technologies fail to combine solar power generation with human power generation.
[0008] To address the aforementioned technical problems, this utility model provides a dual-power bicycle seat cooling device without a physical power source, comprising a photovoltaic panel, a DC generator, a drive belt, and a cooling fan. The photovoltaic panel is electrically connected to the cooling fan to provide power, and the photovoltaic panel is equipped with a photovoltaic panel locking structure for detachable connection and fixation to the bicycle. The DC generator is electrically connected to the cooling fan to provide power, and the DC generator is equipped with a motor locking structure for detachable connection and fixation to the bicycle. The drive belt is detachably fitted around the power input wheel of the DC generator and the pedal axle of the bicycle. The cooling fan is detachably connected and fixed to the bicycle seat, and the airflow direction of the cooling fan is directed towards the bicycle seat.
[0009] In one embodiment, the photovoltaic panel locking structure is disposed on the surface of the photovoltaic panel away from its solar energy collection area.
[0010] In one embodiment, the photovoltaic panel locking structure is a clamp structure, which is used to clamp and lock the photovoltaic panel to the bicycle's frame structure.
[0011] In one embodiment, the photovoltaic panel locking structure is used for detachable connection and fixation to the handlebars of the bicycle.
[0012] In one embodiment, the motor locking structure is used for a detachable connection and fixation to the rod of the bicycle near the pedals.
[0013] In one embodiment, the DC generator is provided with a mounting hole; the motor locking structure is a bolt, which passes through a hole in the rod near the pedal of the bicycle and is threadedly connected to the mounting hole for fixation.
[0014] In one embodiment, the motor locking structure is a clamp structure, which is used to clamp and lock the motor to the pole of the bicycle near the pedal.
[0015] In one embodiment, the power input shaft of the DC generator is driven by an input commutation gearbox. The power input end of the input commutation gearbox is connected to the power input wheel, and the power output end of the input commutation gearbox is connected to the power input shaft of the DC generator. The input commutation gearbox is used to change the power input direction so that the rotation axis of the power input shaft of the DC generator is perpendicular to the rotation axis of the power input wheel.
[0016] In one embodiment, the motor locking structure is located on the input reversing gearbox.
[0017] In one embodiment, the dual-power bicycle seat cooling device further includes a temperature sensor, which, based on the detection result of the temperature sensor, is used to regulate the speed of the temperature-regulating fan.
[0018] The beneficial effects of the utility model are as follows:
[0019] This invention proposes a dual-powered bicycle saddle cooling device that combines solar and human power. Its detachable design allows for easy installation on various bicycles. The core of the device is a small solar panel and a human-powered generator, both working together to power a miniature fan.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0035] This utility model provides a dual-powered bicycle seat cooling device without a physical power source, and its implementation is as follows: Figures 1 to 6 As shown, the bicycle includes a photovoltaic panel 10, a DC generator 20, a drive belt 30, and a cooling fan 40. The photovoltaic panel 10 is electrically connected to the cooling fan 40 for power supply. The photovoltaic panel 10 is connected to a photovoltaic panel locking structure 11, which is used for detachable connection and fixation with the bicycle. The DC generator 20 is electrically connected to the cooling fan 40 for power supply. The DC generator 20 is connected to a motor locking structure 21, which is used for detachable connection and fixation with the bicycle. The drive belt 30 is detachably fitted around the power input wheel 22 of the DC generator 20 and the pedal axle 50 of the bicycle. The cooling fan 40 is detachably connected and fixed to the bicycle seat 51, and the airflow direction of the cooling fan 40 is directed towards the bicycle seat 51.
[0036] In application, the dual-power bicycle seat cooling device can be installed on the bicycle in need of use. The photovoltaic panel 10 can absorb solar energy and generate electricity, which is then transmitted to the cooling fan 40. At the same time, the user can control the power input wheel 22 by pedaling the drive belt 30 to rotate, thereby generating electricity from the DC generator 20. Therefore, the cooling fan 40 can obtain electricity from both the photovoltaic panel 10 and the DC generator 20, enabling it to obtain sufficient power to work in different environments and to provide more efficient heat dissipation for the seat 51.
[0037] It should be noted that the electrical connection between the photovoltaic panel 10 and the cooling fan 40, as well as the electrical connection between the DC generator 20 and the cooling fan 40, can be achieved using wires. The wires can be fixed to the bicycle frame using various methods such as binding, clipping, pasting, or even magnetic attraction, as long as the connection is secure and does not affect the normal use of the bicycle.
[0038] like Figure 4 As shown, in this embodiment, a photovoltaic panel locking structure 11 is provided on the surface of the photovoltaic panel 10 away from its solar energy collection area.
[0039] By adopting this configuration, it can be ensured that there are no obstructions in the area where the photovoltaic panel 10 collects solar energy, allowing the photovoltaic panel 10 to absorb the sun more comprehensively and improve the solar energy conversion efficiency.
[0040] like Figure 4 As shown, in this embodiment, the photovoltaic panel locking structure 11 is set as a clamp structure, which is used to clamp and lock with the bicycle pole structure.
[0041] Since most bicycle frames are constructed using cylindrical rods, the photovoltaic panel locking structure 11 can be made more widely applicable by adopting the above-mentioned setup. Simply tightening and loosening the photovoltaic panel locking structure 11 allows for easy loading and unloading between the photovoltaic panel locking structure 11 and the bicycle.
[0042] Furthermore, when installing and fixing the photovoltaic panel 10 to the bicycle, the photovoltaic panel locking structure 11 is a clamp structure, which allows the installation angle of the photovoltaic panel 10 to be adjusted. For example, after adjusting the photovoltaic panel 10 to be angled upwards, the photovoltaic panel 10 can better absorb solar energy.
[0043] like Figure 4 As shown, this embodiment provides a photovoltaic panel locking structure 11 for detachable connection and fixation with the handlebars of a bicycle.
[0044] With this setup, the photovoltaic panel 10 can be fixed to the front of the bicycle, allowing it to better receive and absorb solar energy during cycling, thus ensuring that the photovoltaic panel 10 obtains more solar energy.
[0045] like Figure 2 As shown, this embodiment provides a motor locking structure 21 for detachable connection and fixation with the rod near the pedals of the bicycle.
[0046] By adopting this configuration, the distance between the DC generator 20 and the bicycle pedals is shortened, which not only makes the installation of the transmission belt 30 at the DC generator 20 and the bicycle pedals more stable, but also improves the power transmission efficiency, thereby improving the power generation efficiency of the DC generator 20.
[0047] like Figure 2 As shown, in this embodiment, the power input shaft of the DC generator 20 is connected to an input commutation gearbox 24. The power input end of the input commutation gearbox 24 is connected to the power input wheel 22, and the power output end of the input commutation gearbox 24 is connected to the power input shaft of the DC generator 20. The input commutation gearbox 24 is used to change the direction of power input so that the rotation axis of the power input shaft of the DC generator 20 is perpendicular to the rotation axis of the power input wheel 22.
[0048] Since the DC generator 20 is generally a long rectangular structure, this configuration changes the power acquisition direction of the DC generator 20, allowing the DC generator 20 to be arranged in the same way as the length of the bicycle frame. This avoids unreasonable space occupation after installation and ensures that the DC generator 20 does not obstruct the bicycle's riding after installation.
[0049] like Figure 6 As shown, in this embodiment, the motor locking structure 21 is installed on the input reversing gearbox 24.
[0050] With this setup, there is no need to make major modifications to standard components such as the DC generator 20. Instead, the DC generator 20 is installed and fixed using the input commutation drive box 24, thereby reducing production and design costs.
[0051] If necessary, it is also feasible to directly install the motor locking structure 21 on the DC generator 20. For example, the DC generator 20 can be provided with a mounting hole 23; and the motor locking structure 21 can be set as a bolt. The motor locking structure 21 passes through the rod hole near the pedal of the bicycle and is threadedly connected to the mounting hole 23 for fixation, which can also achieve the detachable installation of the DC generator 20.
[0052] After adopting this setting method, the motor locking structure 21 can be threaded and fixed to the mounting hole 23 by simply passing the motor locking structure 21 through the rod hole near the pedal of the bicycle. The operation is simple and the installation is firm.
[0053] Of course, not all bicycles may have the corresponding holes. Therefore, in order to improve the compatibility of the motor locking structure 21 with different types of bicycles, it is also possible to consider setting the motor locking structure 21 as a clamp structure. The motor locking structure 21 is used to clamp and lock the bicycle rod near the pedal.
[0054] By adopting this setting, the application range of the motor locking structure 21 can be expanded. The motor locking structure 21 can be easily installed and removed from the bicycle by simply tightening and loosening it.
[0055] Finally, it should be noted that the dual-power bicycle saddle cooling device in this embodiment also includes a temperature sensor. Based on the detection results of the temperature sensor, the dual-power bicycle saddle cooling device is used to regulate the speed of the temperature regulating fan.
[0056] For example, a temperature sensor can be placed on the bicycle saddle 51, so the temperature sensor can monitor the temperature of the saddle 51 in real time. If the temperature of the saddle 51 is too high, the speed of the cooling fan 40 can be increased to increase the heat dissipation efficiency of the saddle 51; if the temperature of the saddle 51 is too low, the speed of the cooling fan 40 can be reduced to reduce the energy consumption of the cooling fan 40.
[0057] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
