Technical Field
The invention relates to the technical field of display screens, in particular to an external light supplementing device, a protective sleeve, a keyboard and a mobile terminal.
Background
Mobile phones and tablet computers are common electronic devices in life, and the electronic device channels are equipped with displays such as LCD and AMOLED, and the displays such as LCD and AMOLED can be lighted up only by backlight or self-luminous light sources, and the blue light carried by the light sources is harmful to human eyes. Display manufacturers have introduced a display that does not require backlighting or self-illumination: the luminous principle of the RLCD or the ink screen is that a reflecting layer is plated in a display, and the aim of light emission is achieved by reflecting external light.
When the ambient light is weak, such as in a night environment or indoors with dark light, the display screen formed by the RLCD or the ink screen cannot clearly see the display content when in use, so that the display screen needs to be supplemented with light by an external light-emitting source. At present, no equipment for supplementing light to the display screen formed by the RLCD or the ink screen exists, so that the display screen formed by the RLCD or the ink screen is inconvenient to use when the ambient light is weak.
Accordingly, the prior art is yet to be improved and developed.
Disclosure of Invention

Further, the light source device includes:
a light emitting source;
and the lens is arranged on the light emitting side of the light emitting source and is arranged at intervals with the light emitting source.
Through the scheme, the luminous source is used for emitting light after being electrified, and the emitted light can enhance the service efficiency and the luminous efficiency of the light through the lens.
Further, the lens is a concave lens, the lens comprising:
the first lens curved surface is positioned on one side of the lens facing the light-emitting source;
and the second lens curved surface is positioned on one side of the lens, which is far away from the luminous source.
In the above scheme, the light that the light emitting source sent carries out the adjustment for the first time through first lens curved surface, carries out the adjustment for the second time through the second lens curved surface again, makes light evenly project on the display screen.
Further, the curvature of the first lens curved surface is larger than that of the second lens curved surface.
According to the scheme, the angle of incident light is controlled by the first lens curved surface, and the light emitted by the light emitting source can enter the lens by adjusting the curvature of the preset first lens curved surface; the angle of emergent light is controlled by the curved surface of the second lens, so that the emergent light can be uniformly projected to a display area.
Furthermore, the external light supplement device also comprises a bottom plate;
the angle adjustment assembly includes:
the gear is connected with the light source part and is rotatably arranged on the bottom plate;
and the rack is arranged on the bottom plate in a sliding manner and is meshed with the gear.
Through above-mentioned scheme, gliding rack promotes the gear revolve, and pivoted gear drives light source spare rotates to the chamfer that makes light source spare send the light and shoot on the display screen is adjusted, and when the different angles of display screen adjustment, the angle that jets out that makes light suits with the display screen. Therefore, the flexible adjustment setting is carried out, and the display screens at different angles can be completely covered.
Furthermore, an accommodating groove is formed in the bottom plate, a guide post is arranged in the accommodating groove, and the rack sleeve slides on the guide post.
Through above-mentioned scheme, the guide post leads the rack, and the rack can directionally slide on the guide post to the rack remains stable, slides steadily at the removal in-process.
Further, the external light supplement device further comprises:
the pressing self-locking assembly is arranged on the light source part and one end, facing the display screen, of the bottom plate;
the first elastic piece is sleeved on the guide post and located on one side, deviating from the display screen, of the rack.
Through the scheme, one end of the light source piece, which is far away from the display screen, is used as a rotating winding point, when the light source piece rotates, one end of the light source piece, which is close to the display screen, can be far away from or close to the bottom plate, and when the light source piece moves close to the bottom plate, the pressing self-locking assembly is pressed to perform self-locking on the pressing self-locking assembly, so that the light source piece is fixed on the bottom plate; when the light source piece needs to be far away from the bottom plate to move, the self-locking pressing assembly which is self-locked is pressed, so that the self-locking pressing assembly is unlocked, the light source piece is separated from the bottom plate, and then the light source piece can be manually lifted, and the angle adjustment of the light source piece is realized.

The guide boss 165 is guided by the guide groove 164, so that the friction part 162 can stably slide and the friction part 162 is prevented from being separated from the mounting groove 136.
As shown in fig. 5, the specific structure of the damping assembly 160 further includes: a rib 124. The protruding strip 124 is disposed on the rack 122 along the sliding direction of the rack 122, and the friction portion 162 abuts against the protruding strip 124. Specifically, the two protruding strips 124 are respectively located on two sides of the width direction of the rack 122, and the protruding strips 124 are arranged along the length direction.
The rib 124 is disposed on the side of the rack 122, so that the side of the rack 122 and the side of the rib 124 form a step, the rib 124 is disposed on the side of the rack 122 away from the display 200, and the side of the rib 124 is disposed near the damping member 160. Thus, when the light source 110 needs to move away from the bottom plate 130, the self-locking pressing assembly 150 which is self-locked is pressed to unlock the self-locking pressing assembly 150, the friction portion 162 abuts against the side surface of the rack 122 at this time, and the friction portion 162 slightly applies or does not apply force to the side surface of the rack 122, so that the light source 110 is separated from the bottom plate 130, and the first elastic member 135 pushes the rack 122 to slide, and the rack 122 pushes the gear 121 to rotate, so that the light source 110 can directly rotate, and the first elastic member 135 pushes the rack 122 to enable the light source 110 to be rapidly ejected. When the first elastic member 135 pushes the rack 122 to slide, so that the position in contact with the friction portion 162 is transited from the side of the rack 122 to the side of the protrusion 124, the friction portion 162 is pressed, and the second elastic member 163 is compressed, so that the friction force between the friction portion 162 and the side of the protrusion 124 is greatly increased, and the rack 122 cannot move due to the pushing force of the first elastic member 135, and the light source 110 is ejected from the hidden place at this time, which is very convenient for the user to manually adjust after holding the rack, and the angle of the light source 110 is manually adjusted by the user, and the angle position is fixed after being adjusted.
To increase the friction force, the side of the convex strip 124 contacting the friction portion 162 is a non-smooth side (not shown), such as a concave strip. The corresponding friction portion 162 may be a rubber friction portion 162, and the side of the rubber friction portion 162 contacting the protruding strip 124 is a non-smooth side.
As shown in fig. 5, in order to make the side surface of the rack 122 smoothly transition with the side surface of the protruding strip 124, an inclined surface 125 is provided on the end surface of the protruding strip 124 facing the display panel 200, and when the side surface of the rack 122 transitions with the side surface of the protruding strip 124, the side surface of the protruding strip 124 is guided by the inclined surface 125 and then pressed by the friction portion 162.
