Technical Field

The application relates to the technical field of electric control, in particular to a control box and a control system.

Background

Most of the existing luminous products can directly look at the lamp beads on the light emergent surface, so that dazzling glare or uneven light spots can be caused. In order to make the light-emitting surface not dazzling or uniform in light spots, a vaporific light-transmitting member is often used as the light-emitting member. The fog-shaped light-transmitting piece realizes no dazzling glare on the light-emitting surface, but occupies most of the structure of the shell, so that the appearance design of the product is limited and is single.

Disclosure of Invention

The application provides a control box and a control system.

In a first aspect, the present application provides a control box, the control box including a housing, a light source, a light guide, and a light outlet. The shell is provided with an installation space and a light outlet groove, and the light outlet groove is communicated with the installation space and the outside. The light source is arranged in the installation space. The light guide piece is arranged in the installation space, the light guide piece is provided with a light inlet surface and a light outlet surface, the light inlet surface is opposite to the light source, and the light outlet surface and the light inlet surface are positioned on different sides of the light guide piece. The light emitting piece is arranged between the light guide piece and the shell, and is provided with a reflecting surface which is positioned on a light path of light rays emitted by the light emitting surface.

In a second aspect, the present application provides a control system, where the control system includes a display device and the control box, and the control box is electrically connected to the display device.

Compared with the prior art, when the control box provided by the application is used, the light source emits light, and the light irradiates the light incident surface and enters the light guide piece through the light incident surface. The light is conducted to the light-emitting surface in the light guide piece, and the light guide piece uniformly diffuses the light out of the light-emitting surface. Light rays transmitted from the light guide piece are transmitted to the light reflecting surface, reflected by the light reflecting surface, transmitted to the outside through the light emitting groove and seen by human eyes. The light guide member uniformly diffuses and spreads the light emitted by the light source to the light emitting member, so that the light effect of the light which is uniform in light emission and free of dark spots and shadows is met. In this application, light propagation to the outside of shell through the reflection of light face with the light of light source, consequently the light source can set up in the shell in a flexible way, makes the light source need not directly reveal outside the shell, so the light source can go out light through light-emitting groove when shining, and the external world can not directly see the light source, and this kind of hidden light-emitting mode has realized that the light-emitting does not have dazzling effect. The light-emitting surface of the light-emitting piece is used for emitting light through the light-emitting groove, the light-emitting area is small, the traditional light-emitting pieces such as a lampshade are not needed to be used for emitting light, space can be vacated for appearance or other structural designs, and various flexible structures and appearance designs can be realized.

Referring to fig. 2 and 3, in the present embodiment, the control box 100 may include a housing 10, a light source 30, a light guide 50, and a light emitting member 70. The housing 10 has an installation space 11 and a light-emitting groove 13, and the light-emitting groove 13 communicates the installation space 11 with the outside. The light source 30, the light guide 50 and the light emitting member 70 are disposed in the installation space 11. The light guide 50 has a light incident surface 51 and a light emergent surface 53, the light incident surface 51 is opposite to the light source 30, the light emergent surface 53 and the light incident surface 51 are positioned on different sides of the light guide 50, and the light reflecting surface 71 is positioned on the light path of the light emitted from the light emergent surface 53.

In use, referring to fig. 3 and 4, the light source 30 emits light, and the light irradiates the light incident surface 51 and enters the light guide 50 through the light incident surface 51. The light is transmitted to the light-emitting surface 53 in the light guide 50, and the light is uniformly diffused from the light-emitting surface 53 by the light guide 50. The light transmitted from the light guide 50 propagates to the light reflecting surface 71, is reflected by the light reflecting surface 71, and propagates to the outside through the light emitting groove 13, and is seen by human eyes. The light guide 50 uniformly spreads and spreads the light emitted from the light source 30 to the light emitting member 70, thereby satisfying the light effect of uniform light emission without light spots and shadows. The light-reflecting surface 71 of the light-emitting member 70 is used for emitting light through the light-emitting groove 13, so that the effect of no dazzling glare of the emitted light is achieved, and the defect that the product appearance design is limited due to the fact that the vaporific light-emitting member emits light is avoided.

Further, in the embodiment of the present application, the light reflecting surface 71 is located on the light path of the light emitted by the light emitting surface 53, and the light emitting slot 13 is located on the light path of the light reflected by the light reflecting surface 71, specifically, the light reflecting surface 53 and the light emitting slot 13 may be at least partially disposed opposite to each other, so that the light can be emitted through the light emitting slot 13 after being reflected on the light reflecting surface 53. For example, the light reflecting surface 71 may be disposed entirely inside the housing 10 (not located in the light emitting groove 13) and opposite to the light emitting groove 13. Alternatively, the light reflecting surface 71 may be disposed entirely within the light emitting groove 13, for example, disposed near a side wall of the light emitting groove 13, and reflect the light transmitted from the light guide 50 out of the light emitting groove 13.

In this embodiment, the light emitting units 32 are LED lamp beads, and the specific number of the light emitting units 32 is not limited in this specification, and the number of the light emitting units 32 may be plural, and plural light emitting units 32 are arranged on the substrate 34 at intervals along the extending direction of the substrate 34, for example, part of the light emitting units 32 are arranged on the first component 341 and the second component 343 at intervals along the second direction Y, and are arranged on the third component 345 at intervals along the first direction X.

The specific material of the substrate 34 is not limited in this specification, and for example, the substrate 34 may be an aluminum substrate or a copper substrate. In this embodiment, the substrate 34 is a printed circuit board, which is a metal-based copper-clad plate with good heat dissipation function, and the single panel is generally composed of three layers, namely a circuit layer (copper foil), an insulating layer and a metal base layer.

It will be understood that "an element is connected to another element" in this specification, and it will be understood that the connection may be directly in contact with the other element or indirectly (e.g., when there is an intervening element therebetween), such as that the other element is mounted on the intervening element, and that the element may be connected to the intervening element, thereby "connecting to the other element". In this embodiment, the substrate 34 may be indirectly connected to the top wall 121, for example, indirectly connected to the top wall 121 through the light guide 50.

In order to receive the light emitted from the light emitting unit 32 to a greater extent, the light guide 50 may be disposed around the light source 30, and in this embodiment, the light source 30 is generally "C-shaped" opening toward the cover plate 16 according to the shape of the substrate 34, so the light guide 50 may also be disposed "C-shaped" opening toward the cover plate 16, and enclosed outside the light source 30, between the light source 30 and the inner peripheral wall of the housing 10.

The light guide 50 has a shape substantially identical to that of the substrate 34, and the light guide 50 may include a first component (not shown), a second component, and a third component connected between the first component and the second component, where the first component and the second component are disposed at a distance from each other. The first component part extends along the second direction Y, the second component part is approximately parallel to the first component part, the third component part extends along the first direction X, and the third component part is approximately perpendicular to the first component part. The first, second and third components of the light guide 50 are disposed in one-to-one correspondence with the first, second and third components 341, 343 and 345 of the substrate 34, respectively.

Referring to fig. 4 and fig. 7, the first, second and third components of the light guide 50 have substantially the same structural composition, and the light guide 50 may include a first light guide 52 and a second light guide 54, for example, the first component of the light guide 50. The first light guide part 52 is located between the light emitting groove 13 and the light source 30, and the second light guide part 54 is connected to one side of the first light guide part 52 facing the light source 30 and protrudes relative to the first light guide part 52; the light incident surface 51 is provided on at least one of the first light guide portion 52 and the second light guide portion 54.

As an example, the first light guide 52 is disposed at a distance from the light source 30 in the first direction X, the first light guide 52 is substantially parallel to and spaced from the inner wall of the housing 10, and the first light guide 52 is also disposed at a distance from the light exit groove 13. The second light guiding portion 54 is connected to a side of the first light guiding portion 52 near the top wall 121 and extends toward the light source 30, and the second light guiding portion 54 is substantially perpendicular to the first light guiding portion 54. The second light guide 54 is connected to the top wall 121, for example, the second light guide 54 may be provided with a connection hole, the top wall 121 may be provided with a structure in which a connection post, a connection protrusion, or the like is coupled to the connection hole, or the second light guide 54 may be fixed to the top wall 121 by a fastener such as a bolt or a screw.

The light incident surface 51 is disposed on a side of the first light guide portion 52 facing the light emitting unit 32, an auxiliary light incident surface 541 is formed on a surface of the second light guide portion 54 adjacent to the first light guide portion 52, the auxiliary light incident surface 541 is substantially perpendicular to the light incident surface 51, the substrate 34 is stacked on a side of the auxiliary light incident surface 541 adjacent to the light incident surface 51, the auxiliary light incident surface 541 and the light incident surface 51 form a bent surrounding structure, so as to surround the light emitting unit 32, thereby achieving a higher light receiving efficiency. The light incident surface 51 and the auxiliary light incident surface 541 commonly receive light emitted from the light emitting unit 32, and thus the light utilization rate is improved. In order to further improve the light utilization rate, the substrate 34 is stacked on a side of the second light guiding portion 54 facing away from the top wall 121, so as to ensure that the divergent light emitted by the light emitting unit 32 is received by the auxiliary light incident surface 541 and the light incident surface 51 as much as possible. The substrate 34 may be connected to the top wall 121 through the second light guide portion 54.

In this embodiment, the light guide 50 may further include a third light guide portion 56, where the third light guide portion 56 is disposed on a side of the first light guide portion 52 away from the light source 30, and protrudes relative to the surface of the first light guide portion 52, and an end of the third light guide portion 56 away from the first light guide portion 52 is approximately abutted against the inner wall of the first housing 12, so that the structural compactness of the control box 100 is improved. The light emitting surface 53 is disposed on a side of the third light guide 56 facing the light emitting element 70 (as shown in fig. 3), and the light emitting surface 53 is oriented substantially along a third direction Z, which is a thickness direction of the housing 10 and intersects (e.g., is perpendicular to) the first direction X and the second direction Y along the third direction Z. That is, the direction of the light emitting surface 53 is approximately parallel to the side wall of the housing 10, and from the above, the direction of the light entering surface 51 is approximately perpendicular to the side wall of the housing 10, the directions of the light emitting surface 53 and the light entering surface 51 intersect, and the light guide 50 changes the direction of the light emitted by the light source 30.

As another example, the second light guide portion 54 is disposed opposite to the light source 30 in the first direction X at a distance, and the first light guide portion 52 is connected to one side of the second light guide portion 54 and extends toward the light emitting member 70. The light incident surface 51 is disposed on a side of the second light guide portion 54 facing the light source 30, and the auxiliary light incident surface 541 is disposed on a surface of the first light guide portion 52 adjacent to the second light guide portion 54.

The light guide 50 may be formed by extrusion, and therefore, although the first light guide 52, the second light guide 54, and the third light guide 56 are designated by different designations to refer to different portions of the light guide 50, these designations should not be construed as limiting the structure of the light guide 50, and these designations are made only for convenience of description, for example, the connection between the first light guide 52, the second light guide 54, and the third light guide 56 may be an integrally formed connection structure, and the first light guide 52, the second light guide 54, and the third light guide 56 may not have an obvious dividing line. In other embodiments, the light guide 50 may be formed by assembling and connecting, so as to reduce the difficulty in manufacturing, for example, the first light guide 52, the second light guide 54, and the third light guide 56 may be assembled together by fasteners after being manufactured independently.

The light emitting unit 52 emits light, the light enters the light guide 50 through the light incident surface 51 and the auxiliary light incident surface 541, and the light guide 50 guides the light and uniformly diffuses the light out through the light emergent surface 53, thereby improving the uniformity of the emergent light. The specific material of the light guide 50 is not limited in this specification, for example, the light guide 52 may be made of a frosted PC (polycarbonate), frosted glass, or the like, and in this embodiment, the light guide 52 is made of a frosted white PC material, so that light can be uniformly diffused to make the light uniform.

In order to improve the installation stability of the light guide 50 in the first housing 12, in this embodiment, the first housing 12 may further include a limiting portion 1212, where the limiting portion 1212 is disposed on the inner side of the top wall 121 and protrudes relative to the surface of the top wall 121. The third light guiding portion 56 is recessed towards one side of the top wall 121 to form a limiting groove 561, and the limiting portion 1212 is embedded in the limiting groove 561. The limit portion 1212 cooperates with the limit groove 561 to provide support for mounting the light guide 50, thereby improving the mounting stability of the light guide 50 in the first housing 12. The number of the limit portions 1212 may be plural, the plural limit portions 1212 are arranged at intervals along the circumferential direction of the first housing 12, and the limit groove 561 may be an entire "C-shaped" groove or plural sub-grooves corresponding to the limit portions 1212.

Referring to fig. 3, fig. 4 and fig. 8, in the present embodiment, the light emitting member 70 is disposed on the side of the light guiding member 50 having the light emitting surface 53, specifically, the light emitting member 70 is located between the first light guiding portion 52 and the light emitting groove 13, and the light emitting member 70 is configured to reflect the light emitted from the light emitting surface 53 to the light emitting groove 13. To receive the light transmitted by the light guide 50 to a greater extent, the light emitting member 70 may be disposed around the light guide 50. Similar to the shapes of the light guide 50 and the light source 30, the light emitting member 70 has an overall shape of a "C" opening toward the cover plate 16, surrounding the light guide 50, between the light guide 50 and the inner peripheral wall of the housing 10. The light emitting member 70 may also include a first component (not shown), a second component and a third component, and the description of the light guiding member 50 and the substrate 34 may be referred to specifically and not repeated herein.
