The invention relates to the field of solar cell panels, in particular to a bicycle solar cell panel with an elastic sealing edge.

Background

With the rapid development of sharing economy and the appearance of sharing bicycles, people can go out more green and convenient, and great convenience is brought to the life of people. The sharing single car is quickly accepted by a large number of consumers in a quick and convenient renting mode, and becomes the most successful sharing economic product. The existing shared bicycle is mainly based on an intelligent lock technology capable of unlocking by scanning codes, rapid unlocking and locking operations are conveniently realized through a mobile terminal, and the intelligent lock is required to have a corresponding communication function and related control devices and driving devices which all need electric power to ensure normal operation of the intelligent lock. Therefore, power supply becomes the essential component part of sharing bicycle, and the solar cell panel that the power supply of present sharing bicycle almost all adopted is as power supply, and solar cell panel mainly installs in the anterior basket bottom of sharing bicycle, and convenience of customers holds article and provides power supply for the intelligence lock.

However, the currently used solar panels for single vehicles still have many problems:

1. the solar cell panel for the bicycle has a multilayer structure, the edge of the solar cell panel is in direct contact with air, the protection effect is poor, water vapor and oxygen are easy to invade from the layers, the aging and the failure of the solar cell panel are accelerated, and the solar cell panel is even layered.

2. Temperature change is big when bicycle solar cell panel insolate and the electricity generation, when installing at the bicycle basket, and its stereoplasm edge and installation fixed orifices and bicycle frame direct contact are fixed, and the panel expansion and contraction receives bicycle frame framework and fixed screw extrusion when cold and hot in turn, leads to deformation such as arch, swell, sunken, causes the panel to damage and splits even.

The Chinese invention patent CN201810801704.7 discloses a solar cell panel with a warning function, which is provided with a movable shielding plate to shield the solar cell panel when a bicycle is not used; in the riding process of a user, the shielding plate is controlled to move to the fixed plate, so that the illuminated surface of the solar cell panel can receive sunlight to generate electric energy to charge the intelligent lock battery in the riding process of the user, and lawless persons can be effectively prevented from attaching small advertisements to the solar cell panel; and meanwhile, a covering object detection sensor is arranged on the light receiving surface of the solar cell panel to judge whether a covering object is attached to the light receiving surface of the solar cell panel after the intelligent lock is closed by a user, if the covering object detection sensor detects the covering object, warning information is sent to a voice prompt module of the intelligent lock to prompt the user to remove the covering object as soon as possible, and if not, the shared bicycle account information of the user is sent to a remote server to penalize the user and forbid the use of the bicycle. But has the following disadvantages: the cover is mainly used for solving the covering problem of the surface of the battery plate, and does not relate to the protection and safety performance of the bicycle plate.

The Chinese invention patent CN201811265195.7 discloses a solar cell panel for a sharing bicycle, which can greatly reduce the number and the probability of the small advertisements of the solar cell panel stuck with adhesive sticker and ensure the power supply. The solar cell module comprises a front packaging plate, a front packaging adhesive film, a solar cell module group, a rear packaging adhesive film and a back plate. The outer side surface of the front packaging plate is composed of supporting columns and lighting areas, the supporting columns are arranged in an array, the tops of the supporting columns are higher than the plane of the lighting areas, when a small advertisement propaganda posts a non-setting adhesive small advertisement, the non-setting adhesive layer can only contact with the tops of the supporting columns and cannot contact with the lighting areas, the contact area is reduced by about 99.5%, the corresponding adhesive force is reduced by about 99.5%, only about 0.5% of the adhesive force is left, the non-setting adhesive small advertisement cannot be firmly adhered, most of the non-setting adhesive small advertisement can be torn by sharing the vibration and the wind power during the driving of a bicycle, the completeness rate of the bicycle is improved. It has simple structure, wide material source, easy production and low cost. The disadvantages are that: the method is mainly used for solving the problem that the small advertisements are stuck on the surface of the battery board to cover the battery board, and does not relate to the protection and safety performance of the bicycle board.

Therefore, what is needed is a solar panel for a bicycle, which can prevent water, oxygen and the like from invading the inside of the solar panel, effectively reduce the deformation and impact damage of the solar panel, and ensure the normal use of the solar panel for the bicycle.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide a bicycle solar panel with an elastic edge seal, which is waterproof, antioxidant, and capable of effectively reducing deformation and impact damage of the panel.

In order to achieve the purpose, the invention designs a bicycle solar cell panel with an elastic sealing edge, which comprises a cell panel body and is characterized in that: the solar cell panel comprises a panel body and is characterized in that the panel body comprises a flexible transparent front plate, a front packaging adhesive film, a solar cell string, a rear packaging adhesive film and a hard supporting rear plate which are sequentially stacked from an illuminated surface to a backlight surface, a plurality of fixing holes are distributed in the edge of the panel body, and elastic soft edges are arranged on the outer edge of the panel body and the edge of each fixing hole.

Preferably, the hard supporting rear plate is a glass fiber modified resin plate or a metal plate.

Preferably, the flexible soft edge is composed of an extension of the flexible transparent front plate and an elastic resin material positioned at the lower layer of the extension.

Further, the elastic resin material is one of an EVA (ethylene vinyl acetate) adhesive film, a POE (polyolefin elastomer) adhesive film, a TPU (thermoplastic polyurethane) adhesive film, butyl rubber, ethylene propylene rubber and nitrile rubber.
