Description

Technical Field

[0001] This utility model relates to a power supply device, and more particularly to a solar panel assembly. Background Technology

[0002] Existing sunshade devices typically include motorized curtains, motorized roller blinds, motorized Venetian blinds, and motorized awnings, which are often powered by solar energy to save energy. Examples include those disclosed in Chinese patent applications 202420097568.9 and 202411465746.X.

[0003] Because the power of the drive motor and the load of the devices differ, as do their usage frequencies, their daily electricity consumption varies, requiring different solar charging speeds. Slow charging (low charging power) may cause the battery to run out and the devices to malfunction.

[0004] Therefore, further improvements are needed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a solar panel assembly that can adjust the charging power to meet the needs of actual use environment.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a solar panel assembly, comprising a solar panel, wherein the solar panel includes a shell and a solar cell; characterized in that:

[0007] The solar panel has two opposite ends along a first direction, and at each end, the solar panel forms a first positive and negative electrode contact.

[0008] The solar panel assembly also includes a connector, which comprises:

[0009] A connector for connecting to the outer casing of a solar panel, wherein the connector connects to one of the solar panels on one of the opposite sides along a first direction, or the connector connects to one of the solar panels on each of the opposite sides along the first direction.

[0010] The second positive and negative contacts are symmetrically arranged on opposite sides of the connector along the first direction. Each second positive and negative contact can be used to electrically connect with the first positive and negative contacts of the solar panel at the corresponding position.

[0011] By setting connectors, solar panels can be modularly designed, and the symmetrical design of the connectors enables the splicing of solar panels. Multiple solar panels can be spliced ​​together by using multiple connectors. After splicing, multiple solar panels are connected in parallel in the charging circuit, which can increase the output current and thus increase the charging power. The number of spliced ​​solar panels can be freely increased or decreased according to the actual use environment to adjust the charging power and meet the charging needs of different charging devices.

[0012] Furthermore, at each end of the solar panel opposite to each other along the first direction, the housing is formed with a slot, and the connector includes a base, on both sides of the base opposite to each other along the first direction, with buckles that engage with the slot, thereby realizing a detachable connection between the solar panel and the connector.

[0013] Furthermore, at each end of the solar panel opposite to each other along the first direction, the outer casing forms a first slot, and the base is symmetrically provided with first plugs that engage with the first slots on both sides opposite to each other along the first direction, thereby enabling positioning of the solar panel and the connector when connected and enhancing the stability of the connection.

[0014] Furthermore, the first slot has two slots spaced apart along the second direction, the first direction and the second direction being perpendicular to each other, and the card slot also has two slots, each located on the side of the first slot away from the other first slot, thereby further enhancing the stability of the connection.

[0015] Furthermore, to facilitate the convenience and accuracy of electrical connection between the solar panel and the connector, a second slot is formed at each end of the solar panel opposite to each other along the first direction. The connector includes a base, and a second plug that is symmetrically arranged on both sides of the base opposite to each other along the first direction to engage with the second slot. The first positive and negative contacts are located in the second slot, and the second positive and negative contacts are arranged on the second plug.

[0016] Furthermore, to facilitate power supply for connection with external devices, the connector also includes a power supply connector for supplying power to external devices, which is electrically connected to the second positive and negative contacts. The power supply connector and the second positive and negative contacts can be electrically connected directly or indirectly.

[0017] Furthermore, to facilitate the installation of the solar panel while receiving solar energy, the housing includes a first housing and a second housing that are interlocked together, the first housing being annular in shape to allow the solar panel to be at least partially exposed.

[0018] Furthermore, to facilitate the transmission of electrical energy from the solar panel to the power supply connector, the connector also includes a circuit board and wires. The circuit board is mounted on the connector base, the second positive and negative contacts are electrically connected to the circuit board, and the wires pass through the connector base to the outside of the connector base to electrically connect the circuit board and the power supply connector.

[0019] To facilitate the routing of the conductors and improve connection stability, the connector includes a base and a groove on the base, with the portion of the conductor located inside the connector passing through the groove.

[0020] To prevent water and dust from entering when one side of the connector is not connected to the solar panel, the connector also includes an end cap that can cover the second positive and negative contacts that are not connected to the solar panel.

[0021] Compared with the prior art, the advantages of this utility model are as follows: by setting connectors, the solar panels can adopt a modular design, and the symmetrical design of the connectors enables the splicing of solar panels. Multiple solar panels can be spliced ​​by using multiple connectors. After multiple solar panels are spliced, they form a parallel structure in the charging circuit, which can increase the output current and thus increase the charging power. The number of spliced ​​solar panels can be freely increased or decreased according to the actual use environment to adjust the charging power and thus meet the charging needs of different charging devices.

In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0031] See Figures 1-6 A solar panel assembly includes a solar panel 1 and a connector 2.

[0032] The solar panel 1 can be generally rectangular in shape, comprising a first housing 11, a second housing 12, and a solar panel 13. The first housing 11 and the second housing 12 can be fastened together to form an outer shell. The solar panel 13 is sandwiched between and fixed to the first housing 11 and the second housing 12. The outer shell is composed of the first housing 11 and the second housing 12, which facilitates the installation of the solar panel 13. The first housing 11 can be annular, so that the solar panel 13 can be exposed between the two housings to receive sunlight.

[0033] The solar panel 1 has two opposite ends along a first direction X (two ends along the length direction in this embodiment). At each end, the integral structure formed by the first housing 11 and the second housing 12 has a first slot 141, a second slot 142, and a slot 15. The first slot 141 may have two slots spaced apart along a second direction Y (spaced apart along the width direction in this embodiment), with the first direction X and the second direction Y perpendicular to each other. There may also be two slots 15, each located on the side of each first slot 141 away from the other. The second slot 142 is located between the two first slots 141. That is, along the second direction Y, the arrangement of the slots is: slot 15, first slot 141, second slot 142, first slot 141, and slot 15.

[0034] The solar panel 13 has a first positive and negative contact 131 at each end, which is located in the second slot 142.

[0035] Connector 2 includes a connector base 21, a cover plate 22, an end cap 23, a wire 24, and a power supply connector 25. Connector base 21 includes a base 214, a first plug 211, a second plug 212, and a latch 213. The number, shape, and position of the first plugs 211 correspond to the first slot 141 of the solar panel 1, and the first plugs 211 can be inserted into the first slot 141 to position the solar panel 1 and connector 2. The number and position of the latches 213 correspond to the slots 15 of the solar panel 1, and the latches 213 snap into the slots 15 to connect the solar panel 1 and connector 2.

[0036] The aforementioned combination of the first plug 211, the second plug 212, and the latch 213 comprises two sets, symmetrically arranged on opposite sides of the base 214 along the first direction X. In this embodiment, the first plug 211 and the first slot 141 provide positioning (and also provide a certain frictional force for connection), and the latch 213 and the slot 15 provide connection. Optionally, other positioning methods and detachable connection methods of the prior art can also be adopted, such as the cooperation of positioning holes and positioning posts, such as plug-in connection, etc.

[0037] The connector 2 also includes second positive and negative contacts 26 disposed on each second plug 212. These second positive and negative contacts 26 are elastic elements. When the second plug 212 is inserted into the second slot 142, the second positive and negative contacts 26 contact the first positive and negative contacts 131 to achieve electrical connection, thereby transmitting electrical energy from the solar panel 1 to the connector 2. The second positive and negative contacts 26 are in the form of spring clips to ensure stability when connected to the first positive and negative contacts 131.

[0038] Connector 2 also includes a circuit board 27, which is mounted on the connector 21. The aforementioned second positive and negative contacts 26 are electrically connected to the circuit board 27. Furthermore, the wire 24 is also electrically connected to the circuit board 27 and extends out of the connector 21. The connector 21 also includes a wire groove 215 on the base 214 for the portion of the wire 24 located within the connector 21 to pass through, defining the routing path of the wire 214 and preventing risks such as disconnection from the circuit board 27 or short circuits due to excessive freedom of movement of the wire 214. A power connector 25 is located at the end of the wire 214 outside the connector 21 for electrical connection to external power-required equipment, such as the motor of an electric curtain.

[0039] The cover plate 22 is placed on the base 214 and can cover part of the circuit board 27 and wires 24, thus serving to prevent water and dust.

[0040] See Figure 1When only one solar panel 1 is used, since it is only connected to one set of first plug 211, second plug 212, clip 213, and second positive and negative contacts 26, the other set of first plug 211, second plug 212, clip 213, and second positive and negative contacts 26 of the connector 21 must be covered by end cap 23 to prevent exposure and subsequent water or dust ingress. See also Figure 7 When the connector 2 connects two solar panels 1, the end cap 23 is not required. In this case, the two solar panels 1 are respectively connected to opposite sides of the connector 2 along the first direction X, achieving mechanical connection and fixation with the connector 21, and electrical connection with the second positive and negative contacts 26. Figure 7 Based on this, by adding connector 2, more solar panels 1 can be spliced ​​together. When splicing two or more solar panels 1, only one of the connectors 2 needs to have a power supply connector 25.

[0041] This enables the modular design of solar panel 1, and the symmetrical design of connector 2 enables the splicing of solar panel 1. Multiple solar panels 1 can be spliced ​​by using multiple connectors 2.

[0042] The solar panel assembly may also include mounting bracket 3, as shown in [reference]. Figure 1 It can be inserted and mated with the second housing 12 for installing the solar panel 1 to the external mounting base. The mounting bracket 3 can be set as a bracket that can be freely adjusted in height. Alternatively, the mounting bracket 3 can be omitted, and the second housing 12 of the solar panel 1 can be directly fixed with double-sided tape.
