Description

Technical Field

[0001] The utility model relates to the technical field of solar lamps, in particular to a solar charging device. Background Art

[0002] Existing solar charging devices that can charge using solar energy mainly include an upper cover, a bottom shell, a solar panel installed on the upper cover, and a battery installed in the bottom shell. The electrical components in the bottom shell need to be connected to external devices through cables. The solar charging device realizes the cable threading by setting a threading hole on the side wall of the bottom shell. The threading hole is small in size. The cable needs to be welded to the circuit board part in the bottom shell first, and then the cable is passed through the threading hole. Finally, the upper cover and the bottom shell are connected and installed. The installation process is relatively cumbersome. In addition, the threading hole is set on the side wall of the bottom shell, which is easy to get water in on rainy days, and the waterproof effect is poor. Utility Model Content

[0003] In order to overcome the deficiencies in the prior art, the utility model provides a solar charging device housing, which is convenient for cable threading and has a good waterproof effect on the threading portion.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A solar charging device shell includes an upper cover and a bottom shell, the bottom shell includes a bottom plate and an edge plate arranged at the edge of the bottom plate, the bottom plate and the edge plate together form a cavity with an upper end opening, the upper cover is sleeved on the outside of the edge plate and closes the cavity to form an accommodating cavity, the bottom plate is provided with a threading portion for threading cables, the threading portion is provided with a threading hole and a sealing cover for covering the threading hole, the sealing cover is detachably connected to the threading portion, the cable passes through the threading portion from the accommodating cavity and extends out of the bottom shell.

[0006] In the above technical solution, when the solar charging device is in use, the solar panel is mounted on the upper end surface of the upper cover, generally facing upward or diagonally upward. The bottom plate and the upper cover are disposed opposite each other, and the threading portion is disposed on the bottom plate, which is not easily exposed to rainwater. Furthermore, the sealing function of the sealing cover ensures that the threading portion is waterproof. When threading is required, the sealing cover can be removed. After the cable is threaded, the threading hole can be sealed with the sealing cover.

[0007] Preferably, the threading part is provided with a limiting countersunk hole arranged side by side with the threading hole, and the sealing cover is provided with a limiting plate, one end of the limiting plate extends into the limiting countersunk hole, and the limiting countersunk hole and the limiting plate together form a U-shaped wiring channel. The cable extends from the threading hole to the outside of the bottom shell along the U-shaped wiring channel, and the limiting plate presses the cable.

[0008] In the above technical solution, after the limit plate presses the cable, the cable extends from the wire hole along the U-shaped wiring channel to the outside of the bottom shell, so that the cable and the bottom shell can be reliably fixed together. When the cable is subjected to external pulling force, the cable can be prevented from transmitting the pulling force to the bottom shell, thereby avoiding the connection point between the cable and the terminal block in the shell from being subjected to force, preventing the cable from being separated from the terminal block, and ensuring the reliability of the electrical connection between the cable and the terminal block.

[0009] Preferably, a first limiting groove for limiting the cable is provided between the threading hole and the limiting countersunk hole, the cable passes through the first limiting groove, and the sealing cover presses the cable at the position of the first limiting groove.

[0010] In the above technical solution, the first limiting groove can limit the cable to avoid cable misplacement, and the sealing cover presses the cable at the position of the first limiting groove, which can further increase the reliability of the connection between the cable and the base plate.

[0011] Preferably, a second limiting groove is provided on a side of the limiting countersunk hole away from the threading hole, the cable passes through the second limiting groove, and the sealing cover presses the cable at the position of the second limiting groove.

[0012] In the above technical solution, the second limiting groove can limit the cable to avoid cable misplacement, and the sealing cover presses the cable at the position of the second limiting groove, which can further increase the reliability of the connection between the cable and the base plate.

[0013] Preferably, the sealing cover is provided with a second connecting column, the threading portion is provided with a second connecting hole corresponding to the second connecting column, and the second connecting column is tightly fitted with the second connecting hole.

[0014] The above technical solution can realize a detachable connection between the sealing cover and the threading portion.

[0015] Preferably, the number of the second connecting posts is two, and the two second connecting posts are arranged on opposite sides of the cable.

[0016] In the above technical solution, the second connecting holes and the second connecting posts are provided correspondingly, and the two second connecting posts can press the cable from both sides of the cable, making the connection between the cable and the base plate more reliable.

[0017] Preferably, a connecting portion is provided on an outer side wall adjacent to the bottom shell and the upper cover, the connecting portion and the bottom shell are integrally formed, and the connecting portion is rotatably connected to a joint.

[0018] In the above technical solution, the connecting portion is disposed on the outer side wall of the bottom shell adjacent to the upper cover, thereby preventing interference between the connecting portion and the threading portion. Furthermore, when the upper cover is facing obliquely upward, the connector is disposed on one side of the upper cover, thereby preventing interference with the upper cover in the height direction. This facilitates the installation of multiple upper covers of varying heights. The connecting portion is integrally formed with the bottom shell, allowing for a reliable connection between the connecting portion and the bottom shell without requiring splicing and installation, thereby improving the overall installation efficiency of the solar charging device.

[0019] Preferably, the threading portion is arranged on a side close to the connecting portion. When in use, the threading portion is relatively low relative to the bottom shell. The solution can make the threading portion relatively low, so that it can be shielded by the structure above and less exposed to rain.

[0020] A solar charging device includes a solar panel and a battery, and also includes the above-mentioned solar charging device shell, the battery is installed in the accommodating cavity, and the solar panel is installed on the upper end surface of the upper cover.

[0021] Preferably, a circuit board is installed in the accommodating cavity, and the circuit board is electrically connected to the solar panel and the battery respectively. The circuit board is provided with a wiring terminal, and the wiring terminal is located above the wire threading hole and faces the wire threading hole; a battery slot is provided in the accommodating cavity, and at least part of the structure of the battery is arranged in the battery slot.

[0022] In the above technical solution, the wiring terminal is located above the wire threading hole and faces the wire threading hole, which makes it convenient to open the sealing cover and directly connect the cable. There is no need to connect the wires first and then thread the wires, which reduces the threading time and improves the installation efficiency of the solar charging device.

[0023] The beneficial effects of the present invention are as follows: (1) the threading portion is arranged on the bottom plate and is not easily exposed to rainwater directly. In addition, the sealing effect of the sealing cover can ensure the waterproofness of the threading portion; (2) after the limit plate presses the cable, the cable extends from the threading hole to the outside of the bottom shell along the U-shaped wiring channel, which can reliably fix the cable and the bottom shell together. When the cable is subjected to external pulling force, the cable can be prevented from transmitting the pulling force to the bottom shell, thereby preventing the connection point between the cable and the terminal block in the shell from being subjected to force, preventing the cable from being separated from the terminal block, and ensuring the reliability of the electrical connection between the cable and the terminal block; (3) the wiring terminal is located above the threading hole and facing the threading hole, which makes it convenient to open the sealing cover and directly connect the cable. There is no need to connect the cable first and then thread the cable, which reduces the threading time and improves the installation efficiency of the solar charging device.

DETAILED DESCRIPTION

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1:

[0035] like Figures 1 to 8 As shown, a solar charging device housing includes an upper cover 1 and a bottom shell 2. The bottom shell 2 includes a bottom plate 2.0 and an edge plate 2.1 arranged at the edge of the bottom plate 2.0. The bottom plate 2.0 and the edge plate 2.1 together form a cavity 2.2 with an upper end opening. The upper cover 1 is sleeved on the outside of the edge plate 2.1 and closes the cavity 2.2 to form an accommodating cavity 2.3. The bottom plate 2.0 is provided with a threading portion 7 for threading cables. The threading portion 7 is provided with a threading hole 7.1 and a sealing cover 7.2 for covering the threading hole 7.1. The sealing cover 7.2 is detachably connected to the threading portion 7. The cable passes through the threading portion 7 from the accommodating cavity 2.3 and extends out of the bottom shell 2. The accommodating cavity 2.3 is provided with a battery slot 2.7 for placing the battery 4. The cables are not drawn in the figure.

[0036] In the above technical solution, when the solar charging device is in use, since the solar panel 3 is mounted on the upper end surface of the upper cover 1, the solar panel 3 generally faces upward or diagonally upward. The bottom plate 2.0 is arranged opposite the upper cover 1, and the wire threading portion 7 is located on the bottom plate 2.0, which is not easily exposed to rainwater. In addition, the sealing effect of the sealing cover 7.2 ensures the waterproofness of the wire threading portion 7. When wire threading is required, the sealing cover 7.2 can be removed. After the cable is threaded, the sealing cover 7.2 can be used to seal the wire threading hole 7.1. The battery compartment 2.7 is used to accommodate the battery 4 to prevent the battery 4 from shaking.

[0037] Preferably, Figures 5 to 8 As shown, the threading portion 7 is provided with a limiting countersunk hole 7.3 arranged side by side with the threading hole 7.1, and a limiting plate 7.4 is fixed on the sealing cover 7.2. One end of the limiting plate 7.4 extends into the limiting countersunk hole 7.3. The limiting countersunk hole 7.3 and the limiting plate 7.4 together form a U-shaped wiring channel 7.5. The cable extends from the threading hole 7.1 to the outside of the bottom shell 2 along the U-shaped wiring channel 7.5, and the limiting plate 7.4 presses the cable.

[0038] In the above technical solution, after the limit plate 7.4 presses the cable, the cable extends from the wire hole 7.1 along the U-shaped wiring channel 7.5 to the outside of the bottom shell 2, so that the cable and the bottom shell 2 can be reliably fixed together. When the cable is subjected to external pulling force, the cable can be prevented from transmitting the pulling force to the bottom shell 2, thereby avoiding the connection point between the cable and the circuit board 12 in the shell from being subjected to force, preventing the cable from detaching from the circuit board 12, and ensuring the reliability of the electrical connection between the cable and the circuit board 12.

[0039] Specifically, a first limiting groove 2.4 for limiting the cable is provided between the threading hole 7.1 and the limiting counterbore 7.3. The cable passes through the first limiting groove 2.4, and the sealing cover 7.2 presses the cable at the position of the first limiting groove 2.4. A second limiting groove 2.5 is provided on the side of the limiting counterbore 7.3 away from the threading hole 7.1. The cable passes through the second limiting groove 2.5, and the sealing cover 7.2 presses the cable at the position of the second limiting groove 2.5. Two second connecting columns 7.6 are provided on the sealing cover 7.2, and two second connecting holes 2.6 corresponding to the second connecting columns 7.6 are provided on the threading portion 7. The second connecting columns 7.6 are tightly fitted with the second connecting holes 2.6. The two second connecting columns 7.6 are arranged on opposite sides of the cable.

[0040] In the above technical solution, the first limiting groove 2.4 can limit the cable to avoid cable misalignment, and the sealing cover 7.2 presses the cable at the position of the first limiting groove 2.4, which can further increase the reliability of the connection between the cable and the base plate 2.0. The second limiting groove 2.5 can limit the cable to avoid cable misalignment, and the sealing cover 7.2 presses the cable at the position of the second limiting groove 2.5, which can further increase the reliability of the connection between the cable and the base plate 2.0. The second connecting hole 2.6 is corresponding to the second connecting column 7.6, and the two second connecting columns 7.6 can press the cable from both sides of the cable, making the connection between the cable and the base plate 2.0 more reliable.

[0041] It is understandable that in another embodiment, the sealing cover 7.2 and the threading portion 7 can be detachably connected by screws.

[0042] Preferably, Figures 1 to 8 As shown, a connecting portion 9 is provided on the outer side wall adjacent to the bottom shell 2 and the upper cover 1. The connecting portion 9 is an integrally formed structure with the bottom shell 2, and the connecting portion 9 is rotatably connected to a joint 10. The threading portion 7 is provided on a side close to the connecting portion 9. In the above technical solution, the connecting portion 9 is provided on the outer side wall adjacent to the bottom shell 2 and the upper cover 1, which can avoid interference between the connecting portion 9 and the threading portion 7. When the upper cover 1 is facing obliquely upward, the joint 10 is provided on one side of the upper cover 1, which is not easy to interfere with the upper cover 1 in the height direction, thereby facilitating the arrangement of multiple upper covers 1 with different heights in the height direction. The connecting portion 9 is integrally formed with the bottom shell 2, so that the connecting portion 9 and the bottom shell 2 can be reliably connected together, and no splicing installation is required, thereby improving the overall installation efficiency of the solar charging device. When in use, the threading portion 7 is relatively low relative to the bottom shell 2. The solution can also make the threading portion 7 relatively low, so that it can be shielded by the structure above and less exposed to rain.

[0043] Example 2:

[0044] like Figures 1 to 8 As shown, a solar charging device includes a solar panel 3 and a battery 4, and also includes the solar charging device housing described in Example 1. The battery 4 is fixed in the accommodating cavity 2.3, and the solar panel 3 is bonded or clamped to the upper end surface of the upper cover 1. A circuit board 12 is installed in the accommodating cavity 2.3, and the circuit board 12 is electrically connected to the solar panel 3 and the battery 4 respectively. The circuit board 12 is provided with a terminal 12.1, which is located above and facing the wire threading hole 7.1.

[0045] In the above technical solution, the wiring terminal 12.1 is located above the wire threading hole 7.1 and faces the wire threading hole 7.1, which makes it convenient to open the sealing cover 7.2 and directly connect the cables. There is no need to connect the cables first and then thread the cables, which reduces the threading time and improves the installation efficiency of the solar charging device.
