detailed description

In order to make the objects, technical solutions and advantages of the present invention more clear, the present invention will be described below with reference to the accompanying drawings. The embodiments are described in further detail.

FIG. 1A is a schematic structural view of a laser receiving structure according to an embodiment of the present invention. The laser receiving structure includes an astigmatism component 110 and at least one laser receiving component 120.

The astigmatism member 110 includes a light incident surface 111 and a light exit surface 112 for scattering the laser light incident on the light incident surface 111 and then emitting it from the light exit surface 112.

As shown in FIG. 1A, the upper surface of the astigmatism member 110 is a light incident surface 111 for receiving laser light 131 emitted from an external laser emitting assembly (not shown); opposite to the light incident surface 111, under the astigmatism member 110 The surface is the light exit surface 112, and the scattered laser light 132 is emitted through the light exit surface 112. In Fig. 1, the light exit surface 112 is formed by the exposed surface of the tapered convex structure. The light incident surface 111 is opposed to the incident direction of the laser light. In FIG. 1A, the incident direction of the laser light 131 is directed to the light incident surface 111 (ie, the incident direction of the laser light 131 is perpendicular to the light incident surface 111), and other possible implementations are described. In the embodiment, the incident direction of the laser light 131 may be at an angle to the vertical direction of the light-incident surface 131 (ie, the laser light 131 may be obliquely incident on the light-incident surface 111), which is not limited in the embodiment of the present invention.

In order for the laser receiving component 120 to receive the scattered laser light 132, the receiving end 121 of the laser receiving component 120 opposes the light exiting surface 112 of the astigmatism component 120. As shown in FIG. 1A, taking the laser receiving component 120 as a laser receiving tube as an example, the receiving end 121 is a receiving head of the laser receiving tube, and the receiving heads of the respective laser receiving tubes are opposite to the light emitting surface 112.

Optionally, the astigmatism component 110 is made of a light transmissive material (such as a light transmissive plastic, a glass or a light transmissive resin, etc.), and the light exiting surface 112 of the astigmatism component 110 includes an array of raised structures, wherein each bulge The dimensions of the structure are the same, and the raised structure may be a tapered raised structure or a curved raised structure. For example, in FIG. 1A, the light exit surface 112 includes a tapered projection structure arranged in an array.

Since the refractive index of the astigmatism member 110 and the air are different, when the laser light incident on the astigmatism member 110 passes through the light-emitting surface 112 formed by the convex structure, the laser light is refracted at the light-emitting surface 112, thereby changing the propagation of the laser light in the air. Direction, expand the projection range of the laser.

Optionally, the astigmatism component 110 can also be made of a material having astigmatism characteristics. Accordingly, the illuminating surface 112 can be made into a smooth surface. After the laser light emitted by the laser emitting component is incident on the astigmatism component 110, the laser light is scattered inside the astigmatism component, and finally re-injected into the air through the light exiting surface. Alternatively, in order to reduce the diffuse reflection generated at the light incident surface when the laser is incident, the light incident surface of the astigmatism member is formed into a smooth surface.

In order to achieve a better astigmatism effect, a certain amount of reservation between the receiving side 121 and the light-emitting surface 112 is required. The spacing allows the scattered laser 132 to reach a larger projection range.

Optionally, adjacent laser receiving components 120 are arranged in an array at predetermined intervals. For example, as shown in FIG. 1A, three laser receiving components 120 are arranged in an array opposite to the light emitting surface 112.

It should be noted that the predetermined interval between the laser receiving components 120 is proportional to the reserved interval between the receiving side 121 and the light emitting surface 112, that is, the larger the reserved interval between the receiving side 121 and the light emitting surface 112, the predetermined The larger the interval, the smaller the number of laser receiving components disposed within the unit length; the smaller the spacing reserved between the receiving side 121 and the light emitting surface 112, the smaller the predetermined interval, correspondingly, the unit length is set. The more the number of the laser receiving components is, the embodiment only describes the three laser receiving components 120 in the laser receiving structure 100 as an example, and does not limit the invention.

Obviously, as shown in FIG. 1B, if the laser light 131 emitted from the external laser emitting device is not scattered, the projection range of the laser 131 (the area between the dotted arrows) is small, and the laser receiving component 120 needs to be separately disposed at the A position (dashed line) In order to ensure that the laser 131 is received; after the astigmatism member 110 provided in the embodiment is used, the projection range of the laser 131 emitted by the laser emitting unit after being scattered by the scattering member 110 (the area between the solid arrows 132) is Large, laser receiving components 120 (shown by solid lines) at positions B and C are capable of receiving the scattered laser light 132, avoiding the need to provide additional laser receiving components 120 at the A position, thereby reducing the total amount of laser receiving components. If the above laser receiving structure is applied to an electronic device, the number of laser receiving components in the electronic device can be significantly reduced, and the total power consumption and manufacturing cost of the electronic device can be reduced.

In summary, in the embodiment, the astigmatism component in the laser receiving structure is used to scatter the received laser beam, thereby expanding the projection range of the laser laser beam and improving the success rate of receiving the laser by the laser receiving component; Under the premise of laser receiving effect, the number of laser receiving components in the device is reduced, and the overall energy consumption of the device is reduced.

2A is a schematic structural view of a light diffusing member according to another embodiment of the present invention. The astigmatism member includes a carrying portion 210 and a plurality of astigmatism portions 220 arranged in an array on the carrying portion 210.

The carrying portion includes a first surface 211 and a second surface 212. The first surface 211 and the second surface 212 are parallel; the first surface 211 is a light incident surface of the astigmatism component, and the second surface of the bearing portion 210 is used to carry a plurality of The astigmatism unit 220.

As shown in FIG. 2A, the carrying portion 210 of the astigmatism member may be a rectangular parallelepiped, the upper surface of the rectangular parallelepiped is the first surface 211 of the carrying portion 210, and the lower surface parallel to the upper surface is the second surface 212 of the carrying portion 210.

The astigmatism portion 220 includes a connecting surface 221 and at least two plane scattering surfaces 222; the connecting surface 221 of the astigmatism portion 220 is fixed to the second surface 212 of the carrying portion 210, and the plane scattering surface 222 of the plurality of astigmatism portions 220 constitutes a light emitting surface of the astigmatism member .

As shown in FIG. 2A, in a possible implementation manner, the astigmatism portion 220 of the astigmatism member may be a triangular prism including a column top surface ABC, a column bottom surface abc, and three adjacent rectangular cylinders, respectively Rectangular cylinder Abba, rectangular cylinder BCcb and rectangular cylinder ACca. Wherein, the column top surface ABC and the column bottom surface abc are all isosceles triangles, AC is the bottom edge of the column top surface ABC, ac is the bottom side of the column bottom surface abc, AB and CB are the column top surface ABC waist, ab and cb are The waist of the abc of the bottom of the column.

The rectangular cylinder on which the base of the isosceles triangle is located is the connection surface 221 of the astigmatism portion 220, and the rectangular cylinder surface on which the isosceles triangle waist is located is the plane scattering surface 222 of the astigmatism portion 220. That is, among the three rectangular cylinders, the rectangular cylinder ACca where the bottom edge ABC and the bottom edge abc are located is the joint surface 221 of the astigmatism portion 220; the rectangular cylinder surface ABba where the waist AB and the waist ab are located is the plane scattering surface 222, the waist BC and The rectangular cylindrical surface BCcb where the waist bc is located is a plane scattering surface 222.

As shown in FIG. 2A, when the astigmatism portion 220 is connected to the carrier portion 210, the rectangular cylindrical surface ACca (connection surface 221) of the triangular prism is fixed to the lower surface (second surface 212) of the rectangular parallelepiped. The other two rectangular cylinders (planar scattering surfaces 222) of the respective triangular prisms are connected to the light-emitting surface constituting the astigmatism member.

In the astigmatism part, the carrying portion 210 and the astigmatism portion 220 are both made of a light transmissive material, and the first surface 211 of the carrying portion 210 is a smooth surface, thereby reducing the diffuse reflection generated when the laser light is projected on the first surface 211. The laser light is incident on the first surface 211 of the carrier 210 and is incident on the scattering portion 220 through the second surface 212 of the carrier 210. When the laser light reaches the plane scattering surface 222 of the scattering portion 220, since the refractive index of the astigmatism member and the air are different, when the laser light incident on the astigmatism member 110 is incident on the air through the plane scattering surface 222, the laser light is at the plane scattering surface 222. The refraction occurs, and the projection range of the laser after the refraction is larger than the projection range when the laser is incident on the first surface 211.

Obviously, the longer the transmission path of the scattered laser light, the larger the projection range of the laser, and accordingly, the smaller the number of laser receiving components (ie, the number of laser receiving components and the distance from the laser receiving component to the light emitting surface). Anti-proportional relationship).

Therefore, when the laser receiving component is disposed, the distance between the laser receiving component and the plane scattering surface 222 can be widened, so that the projection range of the scattered laser light is larger, thereby reducing the number of laser receiving components disposed.

In a possible implementation, the number of planar scattering surfaces in a single scattering portion can be increased. To expand the projection range of the scattered laser light, optionally, the scattering portion 220 in the astigmatism member may be an n-pyramid, n≥3, and n is an integer. As shown in FIG. 2B, the n-pyramid is taken as a triangular pyramid as an example for illustration.

The triangular pyramid includes a cone bottom surface ABC and three cone surfaces, which are a cone ADC, a tapered surface ADB, and a tapered surface DBC. The cone bottom surface ABC is the connection surface 221 of the astigmatism portion 220, and the triangular pyramid surface, that is, the cone bottom surface ABC is fixed to the second surface 212 of the carrier portion 210; the tapered surface ADC, the tapered surface ADB, and the tapered surface DBC are planes of the astigmatism portion 220. Scattering surface 222.

Compared with the use of the triangular prism as the scattering portion 220, only two faces are used as the plane astigmatism surface 222, and when the n pyramid is used as the scattering portion 220, there are n faces simultaneously as the astigmatism surface 222, so that the projection range of the laser after scattering Got an improvement.

When the astigmatism portion 220 adopts an n-pyramid, when n>3, the n-pyramid includes an n-sided cone bottom surface and n tapered surfaces, and the n-sided cone bottom surface is the connection surface 221 of the astigmatism portion 220, and n tapered surfaces. Both are plane scattering surfaces 222 of the astigmatism portion 220.

In the present embodiment, by using the n pyramid as the astigmatism member, the laser light entering the astigmatism member can be simultaneously scattered on the n plane scattering surfaces, thereby further expanding the projection range of the scattered laser light and reducing the number of laser receiving components provided.

In other possible embodiments, the astigmatism surface of the astigmatism portion on the astigmatism member may be an arc-shaped scattering surface, and correspondingly, the laser light incident on the astigmatism member is scattered at the arc-shaped scattering surface. As shown in Fig. 2C, the scattering portion 220 in the astigmatism member is a semi-cylindrical shape.

The semi-cylindrical includes a column top surface 223, a column bottom surface 224, a curved cylinder surface 225, and a rectangular cylindrical surface 226. The rectangular cylindrical surface 226 is a connecting surface 221 of the scattering portion 220, and the semi-cylindrical surface is connected to the second surface 212 of the carrying portion 210 through the rectangular cylindrical surface 226; the curved cylindrical surface 225 is an arc-shaped scattering surface 222 of the scattering portion 220, The laser light incident on the scattering portion 220 is scattered at the curved cylindrical surface 225.

Correspondingly, a plurality of semi-cylindrical arrays are arranged on the carrying portion 210, and each of the semi-cylindrical curved cylindrical surfaces 225 (arc-shaped scattering surfaces 222) are joined to form a light-emitting surface of the entire astigmatism member.

Optionally, as shown in FIG. 2D , the scattering portion 220 may also be a hemisphere. The circular bottom surface 227 of the hemisphere is a connecting surface 221 of the scattering portion 220 , and the curved spherical surface 228 of the hemisphere is the scattering portion 220 . The scattering surface 222, the laser light entering the scattering portion 220, is scattered at the curved spherical surface 228.

Optionally, the astigmatism portion 220 may also adopt a cone. The bottom surface of the cone in the cone is the connecting surface 221 of the astigmatism portion 220, and the conical surface is the arc-shaped scattering surface 222 of the astigmatism portion 220. This is not limited.

It should be noted that the astigmatism components provided by the embodiments shown in FIG. 2A to FIG. 2D are all formed by the connection of the bearing portion and the scattering portion. In the actual manufacturing process, the astigmatism component may also be formed by integral molding, and the present invention is not correct. The manner in which the astigmatism component is made is limited.

In a possible application scenario, the astigmatism component provided by each of the above embodiments may be applied to a competition device casing, which may be a casing of a competition device such as a smart battle toy car or a smart battle toy aircraft.

When playing against a combat device, the laser emitting component disposed at the head of the combat device is usually used to emit laser light forward, and the other combat device receives the laser through a laser receiving component disposed at the tail. Therefore, as a possible implementation, the astigmatism component can be disposed at the tail of the battle equipment housing.

The laser light emitted by the laser emitting device is scattered by the astigmatism component on the outer casing of the competition device, and can be received by the laser receiving component (which is disposed opposite to the light emitting surface of the astigmatism component) disposed in the competition device. Since the projection range of the scattered laser light is large, only a small number of laser receiving components need to be disposed in the battle equipment. For a smaller device such as a combat device, reducing the number of laser receiving components can effectively reduce the overall device. Energy consumption, and avoiding a large number of pins on the battle device control chip is occupied by the laser receiving component.

It is to be noted that the above embodiment is only described by taking the astigmatism component at the tail of the competition device casing. In other possible implementations, the astigmatism component may be disposed on the circumferential side of the competition device casing, and the present invention is not correct. This is limited.

Another point to be noted is that the astigmatism component may be formed by integral molding when the battle equipment casing is made, or may be fixed to the battle equipment casing by spot welding, dispensing, etc., and the present invention does not Limited.

Correspondingly, the laser receiving structure provided by the above embodiment can be applied to a competition device, wherein the astigmatism component in the laser receiving structure is disposed on the peripheral side of the competition device casing, and the laser receiving component in the laser receiving structure is correspondingly disposed in the competition device. Internally, and electrically connected to the laser demodulation circuit in the competition device, after receiving the laser, the laser receiving component demodulates the received laser through the laser demodulation circuit, thereby acquiring information carried in the laser.
