Description

Technical Field

[0001] The utility model relates to the technical field of lamp structures, and particularly relates to a power supply box and a panel lamp including the power supply box. Background Art

[0002] Many existing lamps include a lamp body, a light source assembly, and a power supply box. The light source assembly and the power supply box are arranged on the lamp body, and the power supply box supplies power to the light source assembly. A power supply board is arranged in the power supply box, a power cord is connected to the power supply board, and the power cord passes through the power supply box and is connected to the light source assembly. In order to prevent the power cord from being disconnected from the power supply board after being pulled, generally when producing the power cord, a wire clamping block is formed on the power cord through processes such as injection molding to limit the axial movement of the power cord.

[0003] Different light source assemblies may vary in function and power consumption, so the types and quantities of power supply components and the like matched with different light source assemblies may be different, and the corresponding specifications and sizes of the power supply boards may also be different. The position of the wire clamping block on the power cord is relatively fixed. Since the power supply box is generally fixed on the lamp body, and some power supply boxes are even integrally formed with the lamp body, the space inside the power supply box is relatively stable. If it is necessary to use the same specification of lamp body to match different light source assemblies, in order to ensure a good wire clamping effect, the following situations may occur: 1. According to the specific types and quantities of power supply components, different specifications of power supply boards are used for loading. If different specifications of power supply boards are used, then the power cord also needs to be replaced correspondingly; 2. No matter how the types and quantities of power supply components change, a unified specification and sufficiently large power supply board are used for loading, then no matter which power supply board is used, the power cord does not need to be replaced.

[0004] In the above two situations, to a certain extent, both result in an increase in production costs or a decrease in production efficiency: in situation 1, it is necessary to prepare power cords with different positions of wire clamping blocks, which will increase the consumption of power cord materials and is also more troublesome during assembly; in situation 2, some power supply components actually do not require such a large area of power supply board, which will increase the consumption of power supply board materials. Summary of the Utility Model

[0005] The main purpose of the utility model is to propose a power supply box, aiming to solve the technical problem of large consumption of power cord materials or power supply board materials during the production of lamps in the prior art.

[0006] To achieve the above object, the present utility model provides a power supply box, which comprises a box body and a power supply board; the box body is provided with an opening, and a power supply cover corresponding to the position of the opening is arranged on the box body. A power supply board mounting position is arranged on the box body, and power supply boards with different lengths and / or widths can be mounted on the power supply board mounting position. The power supply board is detachably connected to the power supply board mounting position. A wire passing hole is arranged on the box body, so that a power cord can enter the box body through the wire passing hole and be connected to the power supply board; a wire supporting structure is arranged on the box body, and a wire pressing structure corresponding to the position of the wire supporting structure is arranged on the power supply cover. The wire pressing structure is used to press the power cord on the wire supporting structure to limit the axial movement of the power cord.

[0007] The beneficial effects of the present utility model are as follows: When using this power supply box, different-sized power supply boards - usually with different lengths or widths - can be selected according to actual needs. After installing them on the power supply board mounting position, they are connected to an external electrical structure through a power cord. The power cord extends from the power supply board through the wire passing hole to the electrical structure outside the box body, and then the power supply cover is closed. At this time, the wire pressing structure on the power supply cover presses the power cord on the wire supporting structure, making the power cord axially fixed relative to the power supply board, which can effectively prevent the power cord from detaching from the power supply board. In the present utility model, a power supply board with a matching size can be selected according to the external electrical structure, which is beneficial to reducing the consumption of power supply board materials during production; the power cord is axially fixed by the wire pressing structure and the wire supporting structure. Regardless of how the size of the power supply board changes, the power cord does not need to be replaced. During production, only one or a few specifications of power cords need to be produced to meet the requirements. The fewer the types of power cord specifications, the less tail material and waste material are generated, which is beneficial to reducing the consumption of power cord materials. Moreover, the power cord used does not need to be equipped with a wire clamping block, further reducing the consumption of power cord materials and being beneficial to improving production efficiency.

[0008] Preferably, the wire pressing structure comprises a first pressing tooth assembly. The first pressing tooth assembly comprises a plurality of first pressing teeth arranged in sequence along the extending direction of the wire passing hole. A first pressing strip is arranged on the tooth crest of the first pressing tooth, and the first pressing strip is perpendicular to the extending direction of the wire passing hole, so that the power cord can be more firmly installed on the power supply box and the power cord is protected.

[0009] Preferably, the wire pressing structure further comprises a second pressing tooth assembly. The second pressing tooth assembly comprises a plurality of second pressing teeth arranged in sequence. The arrangement direction of the plurality of second pressing teeth is perpendicular to the extending direction of the wire passing hole. A second pressing strip is arranged on the tooth crest of the second pressing tooth, and the extending direction of the second pressing strip is the same as that of the wire passing hole, so as to limit the movement of the power cord along its own width direction, make the power cord more firmly installed on the power supply box, reduce the swinging amplitude of the power cord, and make the connection between the power cord and the external electrical structure more stable.

[0010] Preferably, the multiple second pressing teeth include two outer pressing teeth and two inner pressing teeth. The two inner pressing teeth are located between the two outer pressing teeth. The height H1 of the outer pressing teeth is higher than the height H2 of the inner pressing teeth, so that while the inner pressing teeth tightly press the middle part of the power cord, the outer pressing teeth can also tightly press the arc-shaped connecting surfaces on both sides of the power cord, thereby fixing the power cord on the power supply box more stably.

[0011] Preferably, the wire supporting structure includes a wire supporting platform. The side wall of the box body provided with a wire passing hole is called the wire passing wall, and the wire supporting platform is arranged on the wire passing wall; the lower side surface of the wire passing hole is flush with the upper side surface of the wire supporting platform, which makes it more convenient to fix the power cord with the pressing structure, avoiding bending the power cord so as not to cause unnecessary damage to the power cord and extending the service life of the power cord.

[0012] Preferably, a wire supporting convex structure is arranged on the upper side surface of the wire supporting platform. While further restricting the movement of the power cord, it can balance the acting forces on the upper and lower sides of the power cord, making the power cord not easily deformed and damaged, protecting the power cord and extending the service life of the power cord.

[0013] Preferably, the power supply cover is rotatably connected to the box body, and its rotation axis extends along the length direction of the box body; a fastening structure is arranged on the power supply cover, and a clamping structure matching the fastening structure is arranged on the box body, so that the power supply cover can be opened or closed to the opening, which is convenient for replacing the power supply board and improves the assembly, replacement and maintenance efficiency.

[0014] Preferably, the fastening structure includes a pressing and fastening part, and the clamping structure includes a pressing and clamping part matching the pressing and fastening part. The pressing and clamping part is arranged beside the wire supporting structure, which is beneficial to reducing the possibility of the pressing structure loosening.

[0015] The present utility model also discloses a panel lamp, which includes the above-mentioned power supply box.

[0016] Preferably, the panel lamp further includes a panel frame, a light source assembly and a power cord. The light source assembly is arranged inside the panel frame. The power supply box is arranged on one of the side frames of the panel frame, and the length direction of the power supply box is the same as the length direction of this side frame. One end of the power cord passes through the wire passing hole and is connected to the power supply board, and the other end is connected to the light source assembly, which can make the overall structure of the panel lamp compact and the position of the power supply box stable, and is beneficial to improving the quality of the panel lamp.

[0032] As Figure 1 、 Figures 3 to 9 shown, a power supply box includes a box body 1 and a power supply board 3; the box body 1 is provided with an opening 15, a power supply cover 2 corresponding to the position of the opening 15 is provided on the box body 1, a power supply board installation position 12 is provided on the box body 1, the power supply board installation position 12 can install power supply boards 3 with different lengths and / or widths, the power supply board 3 is detachably connected to the power supply board installation position 12, a wire passing hole 11 is provided on the box body 1 so that a power cord 50 can enter the box body 1 through the wire passing hole 11 and be connected to the power supply board 3; a wire supporting structure 4 is provided on the box body 1, a wire pressing structure 5 corresponding to the position of the wire supporting structure 4 is provided on the power supply cover 2, and the wire pressing structure 5 is used to press the power cord 50 on the wire supporting structure 4 to limit the axial movement of the power cord 50.

[0033] When using this power supply box, according to actual requirements, a power supply board 3 with different sizes - usually different in length or width - can be selected. After installing it at the power supply board installation position 12, it is connected to an external power-consuming structure through a power cord 50. The power cord 50 extends from the power supply board 3 through the wire hole 11 to the power-consuming structure outside the box body 1, and then the power supply cover 2 is closed. At this time, the wire pressing structure 5 on the power supply cover 2 presses the power cord 50 on the wire supporting structure 4, making the power cord 50 relatively fixed axially with respect to the power supply board 3, which can effectively prevent the power cord 50 from detaching from the power supply board 3. In this embodiment, a power supply board 3 with a matching size can be selected according to the external power-consuming structure, which is beneficial to reducing the consumption of the material of the power supply board 3 during production; the power cord 50 is axially fixed by the wire pressing structure 5 and the wire supporting structure 4. No matter how the size of the power supply board 3 changes, the power cord 50 does not need to be replaced. During production, only one or a few specifications of the power cord 50 are required to meet the requirements. The fewer the specification types of the power cord 50, the less tail material and waste material are generated, which is beneficial to reducing the consumption of the material of the power cord 50. Moreover, the used power cord 50 does not need to be equipped with a wire clamping block, further reducing the consumption of the material of the power cord 50 and being beneficial to improving production efficiency.

[0034] In the prior art, in order to achieve a good wire clamping effect, the size matching of the box body 1 and the power supply board 3 needs to adapt to the position of the wire clamping block on the power cord 50. Since the position of the wire clamping block on the power cord 50 is relatively fixed, the applicable range of the power cord 50 is relatively small. When the size of the power supply board 3 changes, it may be necessary to replace the power cord 50 of different specifications. Here, the "power cord 50 of different specifications" mainly refers to various power cords 50 with different relative positions of the wire clamping blocks. Thus, it is necessary to prepare a variety of power cords 50 of different specifications when assembling the lamp, which is likely to cause waste of the material of the power cord 50. If you don't want to waste the material of the power cord 50, it is necessary to keep the size of the power supply board 3 unchanged. However, for some light source components 30, the corresponding power supply components do not require such a large power supply board 3, which is likely to cause waste of the material of the power supply board 3. Generally speaking, in the prior art, if you want to achieve a good wire clamping effect, either the material of the power cord 50 is wasted or the material of the power supply board 3 is wasted.

[0035] In this embodiment, a power supply board 3 with a suitable size can be selected according to different light source components 30, and there is no need to replace the power cord 50 of another specification - which is beneficial to saving the material of the power supply board 3 and the material of the power cord 50, thus reducing the overall production cost and improving economic benefits.

[0036] In some specific embodiments, referring to Figure 4 and Figure 5, the wire pressing structure 5 includes a first pressing tooth assembly 51. The first pressing tooth assembly 51 includes a plurality of first pressing teeth 511 arranged in sequence along the extending direction of the wire passing hole 11. A first pressing strip 5111 is provided on the tooth crest of the first pressing tooth 511, and the first pressing strip 5111 is perpendicular to the extending direction of the wire passing hole 11.

[0037] The plurality of first pressing teeth 511 arranged in sequence along the extending direction of the wire passing hole 11 form a serrated first pressing tooth assembly 51, which is beneficial to increasing the friction between the wire pressing structure 5 and the power cord 50, making it more difficult for the power cord 50 to move axially; setting the first pressing strip 5111 perpendicular to the extending direction of the wire passing hole 11 on the tooth crest of the first pressing tooth 511 can further restrict the axial movement of the power cord 50, enabling the power cord 50 to be more firmly installed on the power supply box and protecting the power cord 50.

[0038] In some specific embodiments, referring to Figure 4 , Figure 5 and Figure 9 , the wire pressing structure 5 further includes a second pressing tooth assembly 52. The second pressing tooth assembly 52 includes a plurality of second pressing teeth 521 arranged in sequence. The arrangement direction of the plurality of second pressing teeth 521 is perpendicular to the extending direction of the wire passing hole 11. A second pressing strip 5211 is provided on the tooth crest of the second pressing tooth 521, and the extending direction of the second pressing strip 5211 is the same as that of the wire passing hole 11 to restrict the power cord 50 from moving along its own width direction.

[0039] The plurality of first pressing teeth 511 arranged in sequence form a serrated second pressing tooth assembly 52, which is beneficial to increasing the friction between the wire pressing structure 5 and the power cord 50, making it more difficult for the power cord 50 to move in its own width direction; setting the first pressing strip 5111 perpendicular to the extending direction of the wire passing hole 11 on the tooth crest of the first pressing tooth 511 can further restrict the power cord 50 from moving along its own width direction, enabling the power cord 50 to be more firmly installed on the power supply box, reducing the swinging amplitude of the power cord 50, so that the connection between the power cord 50 and the external electrical structure is more stable.

[0040] In some specific embodiments, referring to Figure 4 , Figure 5 and Figure 9 , the plurality of second pressing teeth 521 include two outer pressing teeth 522 and two inner pressing teeth 523. The two inner pressing teeth 523 are located between the two outer pressing teeth 522, and the height H1 of the outer pressing tooth 522 is higher than the height H2 of the inner pressing tooth 523.

[0041] For a general power cord 50, arc-shaped connecting surfaces are provided on both sides thereof. If the heights of multiple second pressing teeth 521 are all kept the same, it may not be possible to press the arc-shaped connecting surfaces on both sides of the power cord 50. Therefore, two outer pressing teeth 522 are specifically provided, and the height of the outer pressing teeth 522 is higher than that of the inner pressing teeth 523, so that while the inner pressing teeth 523 tightly press the middle part of the power cord 50, the outer pressing teeth 522 can also tightly press the arc-shaped connecting surfaces on both sides of the power cord 50, thereby more stably fixing the power cord 50 on the power supply box.

[0042] In some specific embodiments, referring to Figure 4 , Figure 6 and Figure 7 , the wire supporting structure 4 includes a wire supporting table 41. The side wall of the box body 1 provided with the wire passing hole 11 is called the wire passing wall 141, and the wire supporting table 41 is arranged on the wire passing wall 141; the lower side surface of the wire passing hole 11 is flush with the upper side surface of the wire supporting table 41.

[0043] Arranging the wire supporting table 41 on the wire passing wall 141 forms a structure that can support the power cord 50 over a long distance. When installing the power cord 50 on this structure, the power cord 50 is not easily displaced, and it is more convenient to fix the power cord 50 with the wire pressing structure 5, and the fixing effect is better. The lower side surface of the wire passing hole 11 is flush with the upper side surface of the wire supporting table 41, which can avoid bending the power cord 50 so as not to cause unnecessary damage to the power cord 50 and extend the service life of the power cord 50.

[0044] In some other embodiments, the wire pressing structure 5 and the wire supporting structure 4 enclose to form the wire passing hole 11.

[0045] In some specific embodiments, referring to Figure 4 and Figure 6 , a wire supporting convex structure 4111 is provided on the upper side surface of the wire supporting table 41.

[0046] As can be seen from the above content, after the power cord 50 is fixed, there is a strong frictional force between the power cord 50 and the wire pressing structure 5. The setting of the wire supporting convex structure 4111 can increase the frictional force between the power cord 50 and the wire supporting structure 4. While further restricting the movement of the power cord 50, it can balance the acting forces on the upper and lower sides of the power cord 50, making the power cord 50 not easily deformed or damaged, protecting the power cord 50, and extending the service life of the power cord 50.

[0047] Specifically, the wire supporting convex structure 4111 includes wire supporting teeth, and wire supporting strips are provided on the tooth peaks of the wire supporting teeth. The extending direction of the wire supporting strips is perpendicular to the extending direction of the wire passing hole 11.

[0048] In some other embodiments, the wire supporting convex structure 4111 includes square convex blocks, pyramid-shaped protrusions, etc., as long as it can increase the frictional force between the power cord 50 and the wire supporting structure 4.

[0049] In some specific embodiments, referring to Figure 7 , the power supply cover 2 is rotatably connected to the box body 1, and its rotation axis extends along the length direction of the box body 1; a fastening structure 6 is provided on the power supply cover 2, and an engaging structure 7 that is arranged in a matching manner with the fastening structure 6 is provided on the box body 1, so that the power supply cover 2 can be opened or closed to the opening 15.

[0050] Specifically, one of the long sides of the box body 1 is rotatably connected to the power supply cover 2, and the power supply board 3 is generally strip-shaped. When the power supply board 3 is installed in the box body 1, its length direction is consistent with the length direction of the box body 1. With such an arrangement, when the power supply cover 2 opens the box body 1, the power supply board 3 can be completely exposed, facilitating the replacement of the power supply board 3 and improving the assembly, replacement, and maintenance efficiency.

[0051] Compared with the setting where the rotation axis of the power supply cover 2 extends along the width direction of the box body 1, in this embodiment, the space required to open the power supply cover 2 is smaller, which is more convenient for the installation, replacement, and maintenance of the power supply board 3.

[0052] After the power supply cover 2 and the box body 1 are connected through the engaging structure 7 and the fastening structure 6, the wire pressing structure 5 also presses the power cord 50 on the wire supporting structure 4 at the same time, completing the fixation of the power cord 50.

[0053] Specifically, the engaging structure 7 includes a plurality of engaging members 71, the fastening structure 6 includes a plurality of fastening members 61, and the plurality of engaging members 71 and the plurality of fastening members 61 correspond to each other one by one.

[0054] In some other embodiments, one of the short sides of the box body 1 is rotatably connected to the power supply cover 2, and its rotation axis extends along the width direction of the box body 1.

[0055] In some specific embodiments, referring to Figure 4 , the fastening structure 6 includes a wire pressing and fastening portion 62, the engaging structure 7 includes a wire pressing and engaging portion 72 that is arranged in a matching manner with the wire pressing and fastening portion 62, and the wire pressing and engaging portion 72 is arranged beside the wire supporting structure 4.

[0056] By specifically setting the wire pressing and fastening portion 62 and the wire pressing and engaging portion 72, while making the connection between the power supply cover 2 and the box body 1 more stable, it is beneficial to reduce the possibility of the wire pressing structure 5 loosening, thereby improving the position stability of the power cord 50 on the power supply box, which is beneficial to the protection of the power cord 50 and the connection stability between the power supply box and the external electrical structure.

[0057] Specifically, the wire pressing and engaging portion 72 is one or more engaging members 71 arranged beside the wire supporting table 41, and the wire pressing and fastening portion 62 is a fastening member 61 that is arranged in a matching manner with the engaging member 71.

[0058] In some specific embodiments, referring toFigure 7 The box body 1 includes two first side plates 13 extending along the length direction and two second side plates 14 extending along the width direction. The power board mounting position 12 is provided between the two first side plates 13. The power board 3 can be directly clamped between the two first side plates 13. The power board 3 and the wire passing hole 11 are arranged along the length direction of the power board 3.

[0059] Generally speaking, the box body 1 is in the shape of a cuboid. Correspondingly, the power board 3 is generally in the shape of a long strip. For power boards 3 of different specifications, the difference generally lies in the length. Accordingly, in this embodiment, the power board mounting position 12 is provided between the two first side plates 13. No matter how the length of the power board 3 changes, as long as the width of the power board 3 remains unchanged, it can be clamped on the box body 1.

[0060] In some other embodiments, due to special requirements, there are also some types of power boards 3 whose specifications are different in width. Therefore, the power board 3 can be mounted between the two second side plates 14.

[0061] In some other embodiments, the power board 3 is locked on the box body 1 by screws. In this fixing form, no matter how the length and width of the power board 3 change, as long as the box body 1 can accommodate the power board 3, the power board 3 can be installed in the box body 1.

[0062] This embodiment also discloses a panel light, including the above power box.

[0063] In some specific embodiments, referring to Figure 1 and Figure 2 the panel light further includes a panel frame 10, a light source assembly 30 and a power cord 50. The light source assembly 30 is arranged inside the panel frame 10. The power box is arranged on one of the side frames 101 of the panel frame 10, and the length direction of the power box is the same as the length direction of the side frame 101. One end of the power cord 50 passes through the wire passing hole 11 and is connected to the power board 3, and the other end is connected to the light source assembly 30.

[0064] Specifically, a recessed portion 102 is formed in the middle part of the panel frame 10. The light source assembly 30 is arranged in the recessed portion 102. The power box is arranged on the back of the panel frame 10. Looking from the back of the panel frame 10, the recessed portion 102 is protruding. The four side frames 101 of the panel frame 10 surround the recessed portion 102 and are connected end to end. The power box is in the shape of a cuboid as a whole. If it is arranged in the middle part of the panel frame 10, it will increase the height of the panel light and is not convenient for installation, transportation, etc. Therefore, the power box is arranged on the side frame 101 and is consistent with the length direction of the side frame 101. Such an arrangement can make the overall structure of the panel light compact, the position of the power box stable, and is beneficial to improving the quality of the panel light.

[0065] In some specific embodiments, referring to Figure 1 andFigure 2 , an extension plate 20 is provided on the panel frame 10. A display screen 40 is provided on the front surface of the extension plate 20, and a digital display control box 201 communicatively connected to the display screen 40 is provided on the back surface of the extension plate 20. The digital display control box 201 can control the display screen 40 to display information such as brightness and light color, enabling users to intuitively understand and use the panel light.

[0066] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
