Description

Technical Field

[0001] The present disclosure relates to the technical field of trolleys, and particularly to a solar-powered assisted trolley. Background Art

[0002] A trolley is a handling vehicle that can work in places where motor vehicles are inconvenient to use, so as to facilitate short-distance cargo turnover. Traditional trolleys rely entirely on manual pushing or pulling, with low work efficiency. Moreover, due to human limitations, the amount of goods transported is small. For this reason, technicians have developed electric trolleys with built-in motors, and further developed electric trolleys that use solar energy as a form of electrical energy supplement, significantly improving the work efficiency and transportation capacity of trolleys.

[0003] In related technologies, for example, a utility model patent with the publication number "CN 203946117 U" discloses a solar panel vehicle, in which the solar components are arranged on a solar component bracket between the middle parts of two support pipes; when the solar panel vehicle is not in use, the support pipes are laid flat so that the working surface of the solar components faces upward for solar charging. However, when the solar panel vehicle is in use, the support pipes are in an upright state, and the solar components are easily damaged during the process of carrying goods.

[0004] Another example is a utility model patent with the publication number "CN 209064124 U" that discloses a trolley. The photovoltaic power generation components for converting solar energy into electrical energy are arranged on the light-facing surface of the load-carrying plate. However, in order to prevent the goods placed on the load-carrying plate from damaging the photovoltaic power generation components, it is necessary to protect the surface of the photovoltaic power generation components. For example, a waterproof protective layer is provided on the flexible thin-film photovoltaic components disclosed in this patent document. However, this will inevitably increase the equipment cost, and scratches or dirt are easily left on the flexible thin-film photovoltaic components during the process of carrying goods, which will affect the power generation efficiency of the photovoltaic power generation components.

When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0028] In addition, the "first", "second" and similar terms used in the present disclosure do not denote any order, quantity or importance, but are only used to distinguish different parts. "Vertical" is not strictly vertical, but within the allowable error range. "Parallel" is not strictly parallel, but within the allowable error range. Words such as "including" or "comprising" mean that the elements before the word cover the elements listed after the word, and do not exclude the possibility of also covering other elements.

[0029] It should also be noted that in the description of the present disclosure, unless otherwise clearly defined and limited, the terms "mounted", "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances. When it is described that a specific device is located between a first device and a second device, there may or may not be an intermediate device between the specific device and the first device or the second device.

[0030] All terms used in the present disclosure have the same meanings as those understood by those of ordinary skill in the art to which the present disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, such as those, should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such here.

[0031] Technologies, methods and devices known to those of ordinary skill in the relevant fields may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the specification.

[0032] In combination withFigure 1 and Figure 2 As shown in Figure 2 , the present disclosure provides a solar-assisted trolley, which includes a load-carrying board 10 and a solar power generation component. A pushing and pulling mechanism 20 extending upward is provided on one side of the load-carrying board 10, and a traveling mechanism 30 and a motor 40 for providing power to the traveling mechanism 30 are provided on the bottom surface of the load-carrying board 10; the solar power generation component is used to convert light energy into electrical energy required by the motor 40. The solar power generation component includes a solar panel 50 for receiving light. The solar panel 50 includes a first solar panel unit 51 and a plurality of second solar panel units 52 connected in sequence. The first solar panel unit 51 is provided on one side of the load-carrying board 10 where the pushing and pulling mechanism 20 is fixed. The plurality of second solar panel units 52 have a working position spread along the extending direction of the pushing and pulling mechanism 20, and a storage position folded in sequence and stacked above the first solar panel unit 51.

[0033] It can be understood that the solar power generation component can convert light energy into electrical energy and supply it to the motor 40, and the traveling mechanism 30 is driven by the motor 40, thereby overcoming the defects of low working efficiency and small single-time cargo handling capacity existing in the existing trolley by manual pushing and pulling.

[0034] In the related art, the solar panel 50 is a key part of the solar power generation component, which directly or indirectly converts light energy into electrical energy through the photovoltaic effect or the photochemical effect. If the solar panel 50 is damaged, it will directly affect the conversion of light energy and even directly affect the service life of the solar power generation component.

[0035] In the technical solution provided by the present disclosure, by designing the solar panel 50 to include a first solar panel unit 51 and a plurality of second solar panel units 52 connected in sequence, when the trolley is not in use, the plurality of second solar panel units 52 are spread along the extending direction of the pushing and pulling mechanism 20 to receive light with a larger light-receiving area and convert it into electrical energy; when the trolley needs to be used, the plurality of second solar panel units 52 are folded in sequence and stacked above the first solar panel unit 51 to complete the storage of the solar panel, preventing the solar panel 50 from being damaged during the use of the trolley. The solar-assisted trolley provided by the present disclosure can use solar energy as a form of electrical energy supplement and can effectively prevent the solar panel 50 from being bruised during the use of the trolley.

[0036] In some embodiments, adjacent two second solar panel units 52 are connected by hinges. In this way, when storing, the plurality of second solar panel units 52 can be folded in sequence. As Figure 1As shown, in some embodiments, there are four second solar panel units 52. The lowermost second solar panel unit 52 is hinged to the side of the first solar panel unit 51. After the four second solar panel units 52 are folded in sequence, they exactly overlap the first solar panel unit 51.

[0037] It can be understood that in the embodiments of the present disclosure, the loading plate 10 can be adaptively changed according to the type of the goods carried. Exemplarily, the loading plate 10 is set as a flat plate, so that various types of goods can be conveniently loaded and unloaded.

[0038] In the embodiments of the present disclosure, the first solar panel unit 51 of the solar panel 50 can be arranged on the loading plate 10 in any suitable form. In some embodiments, a groove 11 is provided on one side of the fixed push-pull mechanism 20 of the loading plate 10. The first solar panel unit 51 is installed in the groove 11, and multiple second solar panel units 52 are sequentially folded and accommodated in the groove 11. By providing the groove 11 to install the first solar panel unit 51 of the solar panel 50 and accommodate multiple sequentially folded second solar panel units 52, the overall protection effect of the solar panel 50 is ensured.

[0039] In some embodiments, the upper top surface of the multiple second solar panel units 52 after being sequentially folded is flush with the upper side surface of the loading plate 10.

[0040] It can be understood that through the above settings, the storage position of the solar panel 50 can also be used to carry goods, thereby increasing the loading capacity of the goods or facilitating the adjustment of the placement method of the goods on the loading plate 10. And it can be understood that since the solar panel 50 is stored horizontally at a position equal to the height of the loading plate 10, it will neither be damaged by the carried goods nor be easily damaged by hitting other objects during the movement of the trolley.

[0041] In some embodiments, the traveling mechanism 30 includes at least two rotating shafts 31 rotatably arranged on the bottom surface of the loading plate 10. Rollers 32 are respectively arranged at both ends of the rotating shaft 31, and at least one rotating shaft 31 is in transmission connection with the output shaft of the motor 40.

[0042] It can be understood that by rotatably arranging two parallel and spaced rotating shafts 31 on the bottom surface of the loading plate 10, the movement of the loading plate 10 can be realized, and the output shaft of the motor 40 is in transmission connection with one of the rotating shafts 31 to provide power for the traveling mechanism 30 to drive the loading plate 10 to move. In some embodiments, as shown in Figure 3 As shown, there are two rotating shafts 31, and the rotating shaft 31 close to the push-pull mechanism 20 is in transmission connection with the output shaft of the motor 40.

[0043] In the embodiment of the present disclosure, the output shaft of the motor 40 may be transmission-connected to the rotating shaft 31 in any appropriate form. For example, the output shaft of the motor 40 drives the rotating shaft 31 to rotate via a pulley.

[0044] In some embodiments, the push-pull mechanism 20 includes at least two support members 21 , the bottom ends of the at least two support members 21 are fixed to one side of the carrier plate 10 , and a horizontal handle 22 is disposed between the top ends of the at least two support members 21 .

[0045] In some embodiments, the push-pull mechanism 20 includes two support members 21 , the bottom ends of the two support members 21 are fixed to one side of the carrier plate 10 , and a horizontal handle 22 is disposed between the top ends of the two support members 21 .

[0046] In some embodiments, at least two upper ends of the supporting members 21 are respectively provided with a bending portion 211 extending upward along a side away from the carrier 10. In the embodiment of the present disclosure, by providing the bending portion 211, a certain distance is formed between the carrier and the solar-powered trolley, thereby preventing the carrier 10 from hitting the carrier's legs or feet during the movement.

[0047] In the embodiment of the present disclosure, the purpose of spreading out the multiple second solar panel units 52 along the extension direction of the push-pull mechanism 20 is to enable the multiple second solar panel units 52 to rely on the push-pull mechanism 20 to receive light. In order to further improve the stability of the multiple second solar panel units 52 during the light receiving process, in some embodiments, the push-pull mechanism 20 is provided with fixing parts for fixing the spread out multiple second solar panel units 52.

[0048] In some embodiments, the fixing member is a strap 23 provided on the push-pull mechanism 20. It is simple and convenient to fix the plurality of second solar panel units 52 by providing the strap 23. For example, the top second solar panel unit 52 can be pulled and fixed on the horizontal handle 22 of the push-pull mechanism 20 by the strap 23.

[0049] In some embodiments, the solar power generation assembly further includes a storage battery, which is used to store the electric energy generated by the solar power generation assembly. When the solar power generation assembly converts light energy into electric energy, it can be stored in the storage battery. When the cart needs to be used, the storage battery can be used to provide electric energy to the motor 40. By providing a storage battery to store the electric energy generated by the solar power generation assembly, the solar-powered cart can also be used in scenes without light, thereby extending the working time of the solar-powered cart and expanding the application scenarios of the solar-powered cart.

[0050] It is understandable that the battery can also provide electrical energy for other electrical devices disposed on the solar-powered trolley, such as a horn and lights.

[0051] In some embodiments, the solar-assisted trolley further includes a controller disposed on the push-pull mechanism 20, and the controller is configured to control the output power of the motor 40. It can be understood that the output power of the motor 40 is adjusted by the controller, and then the traveling speed of the traveling mechanism 30 is controlled to meet the needs of the operator and improve the cargo handling efficiency of the trolley.

Those skilled in the art should understand that the above embodiments can be modified or some technical features can be equivalently replaced without departing from the scope and spirit of the present disclosure. In particular, as long as there is no structural conflict, the technical features mentioned in each of the embodiments can be combined in any way.
