Detailed Description
The utility model will be described below with reference to several examples. It is to be understood that these embodiments are described in order to enable others skilled in the art to better understand and implement the present invention, and are not intended to represent or imply any limitation on the scope of the present invention.
As shown in fig. 1 to 8, one or more embodiments of the power supply device for a dc motor of the present invention include a mounting base 101, a photoelectric conversion element 102, a rechargeable battery waterproof tube 104, a first connecting wire 105, a second connecting wire 106, a waterproof tube accommodating passage 107, and an accommodating passage end cap 108.
Specifically, the photoelectric conversion element 102, which may be, but not limited to, a solar panel, is disposed on the front side of the mounting seat 101, and a light receiving side on the photoelectric conversion element 102 is disposed corresponding to the outside, and is configured to convert at least a part of energy of light received from the light receiving side on the photoelectric conversion element 102 into electric energy.
A rechargeable battery, which may be but not limited to a lithium battery, is disposed on the mounting seat 101 for storing the electric energy converted by the photoelectric conversion member 102.
It should be noted that, in the prior art, the lithium battery has the advantage of large capacity of storing electric energy with the same volume, and is widely used, but may be other used batteries (such as nickel-metal hydride batteries) or batteries with charging function under development.
A rechargeable battery waterproof tube 104 for hermetically disposing the rechargeable battery therein. This provides the possibility of protecting the rechargeable battery from water erosion caused by non-human factors and/or human factors such as rain and snow.
In one example, the waterproof tube 104 of the rechargeable battery may be made of a material having waterproof and corrosion-resistant properties, such as aluminum, steel, etc.
And a first connecting wire 105 connecting the photoelectric conversion element 102 and the rechargeable battery, for transmitting the electric energy converted by the photoelectric conversion element 102 to the rechargeable battery. And a second connecting wire 106 for connecting the rechargeable battery and the external DC motor and transmitting the electric energy in the rechargeable battery to the DC motor.
The waterproof pipe accommodating channel 107 and the accommodating channel end cover 108 are further included, the waterproof pipe accommodating channel 107 is arranged on the mounting seat 101 and is arranged along the longitudinal extension of the mounting seat 101, and at least one end of the waterproof pipe accommodating channel 107 is communicated with the outside. And a receiving channel end cover 108 for blocking a port on the waterproof tube receiving channel 107, which is communicated with the outside. When the battery is detached, the rechargeable battery waterproof tube 104 with the rechargeable battery can be replaced by inserting or removing the rechargeable battery through the port communicating with the outside.
In one example, the photoelectric conversion element 102 is disposed along the front side of the mounting seat 101, obliquely from top to bottom and from inside to outside. In this way, it is possible to increase the area of the light receiving side by arranging the photoelectric conversion element 102 obliquely under the condition that the size of the mount 101 is limited.
In one example, the power supply device further includes a third connecting lead 112 and a channel end cap hole 116 connecting the rechargeable battery with an external power source for delivering external power to the rechargeable battery. A channel end cap aperture 116, which opens onto the channel-receiving end cap 108, cooperates with the third connecting lead 112. When in use, the outer end of the third connecting wire 112 is connected with a wire connected with an external power supply, or directly connected with the external power supply.
It should be noted that the third connecting wire 112 is arranged to receive the electric energy from the external power source to provide the power source for the dc motor or other electric tools when the photoelectric conversion element 102 cannot absorb enough light energy from the outside for converting into the electric energy due to weather.
In one example, in order to make it possible to increase the amount of electricity stored in the rechargeable battery itself, the waterproof tube accommodating passage 107 has a length substantially the same as the longitudinal length of the mount 101. The length of the rechargeable battery is substantially the same as the length of the waterproof tube accommodating passage. Therefore, under the condition of a certain length of the mounting seat 101, the volume of the rechargeable battery can be increased as much as possible, and the electric storage capacity of the rechargeable battery is correspondingly increased.
In one example, in order to increase the waterproof capability of the waterproof tube accommodating passage 107, the waterproof tube accommodating passage 107 is provided below the front side of the mount 101. Thus, the water from the outside is mostly dropped on the photoelectric conversion element 102 located above the waterproof tube accommodating passage 107, and does not directly flow to the portion of the mounting seat 101 corresponding to the waterproof tube accommodating passage 107.
In one example, both ends of the waterproof tube accommodating passage 107 communicate with the outside, respectively. The number of the accommodating channel end covers 108 is two, and the two accommodating channel end covers are respectively connected with the ports at the two ends of the waterproof pipe accommodating channel 107. This arrangement facilitates the rechargeable battery waterproof tube 104 to be able to enter or exit the waterproof tube accommodating passage 107 from a side of a relatively large installation space in a narrow installation environment.
In one example, the power supply further includes a first cavity 115, and the first cavity 115 is disposed on a front side of the mounting base 101.
It should be noted that the first chamber 115 can be provided not only for arranging internal wiring but also for facilitating heat dissipation of the photoelectric conversion member 102 and the rechargeable battery waterproof tube 107 in which the rechargeable battery is mounted.
In one example, to facilitate replacement of the rechargeable battery, one end of the rechargeable battery waterproof tube 104 communicates with the outside. The waterproof tube 104 of the rechargeable battery further comprises a waterproof tube end cover 110 and an end cover wire guide hole 111. The periphery of the waterproof tube end cover 110 is sealed (for example, but not limited to, by using cement, or by providing a pair of connecting threads on the outer side of the waterproof tube end cover 110 and the inner side of the port of the waterproof tube 104 of the rechargeable battery, and additionally providing a sealing ring) on the port of the end of the waterproof tube 104 of the rechargeable battery, which is communicated with the outside. And the end cover wire hole 111 is formed in the waterproof tube end cover 110 and is used for allowing the wires (including the first connecting wire 105, the second connecting wire 106 and the third connecting wire 112) to extend out of the rechargeable battery waterproof tube 104. The end cover wire hole 111 is connected with the wire at the upper part of the end cover wire hole 111 in a sealing way.
It should be noted that the number of the end cap wire holes 111 may be the same as or less than the number of the wires. In addition, the end cap wire guiding hole 111 and the upper portion of the wire disposed on the end cap wire guiding hole 111 can be connected by, but not limited to, sealing with cement.
In one example, to facilitate ease of wire connection. The power supply may further include an electrical connector 120, and the electrical connector 120 may be an electrical plug, an electrical socket, or both. Thus, when the first connecting wire 105 is electrically connected with the photoelectric conversion element 102, the second connecting wire 106 is electrically connected with the external dc motor, and the third connecting wire 112 is electrically connected with the external power supply, the electrical connection or disconnection can be realized only by the plugging and unplugging actions of the electrical plug 120.
In one example, the electrical connector 120 disposed on the third connecting lead 112 may be positioned to correspond to the access cover aperture 116, which facilitates the insertion and removal of the rechargeable battery from an external power source.
In one example, the photoelectric conversion member 102 is easily attached and detached. The photoelectric conversion element 102 has a plate-like structure. The power supply device further includes a pair of photoelectric conversion element slots 109. The pair of photoelectric conversion element insertion grooves 109 are provided on the front surface side of the mount 101, extend in the longitudinal direction of the mount 101, and are provided in a vertically corresponding manner, and are used for inserting into the plate-shaped photoelectric conversion element 102 from the opposite upper and lower sides.
In one example, a mounting bracket 113 and a pair of bracket mounting slots 114 are also included. The pair of bracket mounting grooves 114 are provided on the back surface side of the mounting base 101 at intervals corresponding to each other in the vertical direction, and the mounting bracket 113 is provided in the pair of mounting grooves 114 on the upper side and the lower side, respectively, in use.
When the installation is performed, the installation bracket 113 is fixed to an external load-bearing part (such as a wall) by passing through the bracket installation hole 118 through the installation nail, and then the installation bracket 113 is inserted into the pair of bracket installation grooves 114.
In one example, a pair of bracket mounting grooves 114 are provided extending in the longitudinal direction of the back surface side of the mount 101, and the length of the pair of bracket mounting grooves 114 is substantially the same as the longitudinal length of the back surface side of the mount 101, and both the front and rear sides of the pair of bracket mounting grooves 114 in the longitudinal direction of the back surface side of the mount 101 communicate with the outside. Therefore, a plurality of mounting brackets 113 can be accommodated, the adjustment range of the interval between the mounting brackets 113 is enlarged, and the mounting is convenient.
In one example, the distance between the bottoms of the pair of the bracket mounting grooves 114 is less than 2 to 10 mm of the height of the mounting bracket 113. The mounting bracket 113 further includes an elastic supporting leg 117. When the mounting is performed, the elastic support legs 117 are compressed, so that the mounting bracket 113 enters and engages with the pair of bracket mounting grooves 114 in a relatively upper side and a relatively lower side. This not only improves the firmness of the connection between the mounting bracket 113 and the mounting seat 101. In addition, when mounting, the mounting bracket 113 can be directly mounted from between the spaces of the pair of bracket mounting grooves 114 without entering from a side port on one longitudinal side of the pair of bracket mounting grooves 114 communicating with the outside.
In one example, the mounting bracket 113 further defines a second connecting wire receiving groove 119 for receiving a portion of the second connecting wire 106.
The elastic support leg 117 may be made of an elastic material, may have an elastically deformable structure, or may be a combination of the two. As shown in fig. 7 to 8, the number of the elastic supporting legs 117 is a pair of supporting legs formed in a shape of a Chinese character 'ba' and made of plastic. In this way, when in use, the pair of splayed support legs are compressed and narrowed, so that the mounting bracket 113 enters the pair of bracket mounting grooves 114 through the spaced region of the pair of bracket mounting grooves 114, and then the compressed and narrowed splayed support legs are gradually widened in the process of returning to the original state after losing the external force, so that the opposite upper and lower sides of the mounting bracket 113 are engaged with the pair of bracket mounting grooves 114.
