It should be understood that "first," "second" distinct objects may be interchanged under appropriate circumstances such that embodiments of the present application described herein may be implemented in an order other than those illustrated or described herein.
The detection device according to the embodiment of the present application will be described in detail below with reference to fig. 1 to 11.
The detection device comprises: a body 110, a light blocking member 120, a detecting member 130, and a light emitting member 140. The body 110 has an accommodating space and an opening 113; the opening 113 communicates with the accommodating space; the light-blocking member 120 is disposed in the accommodating space, and the light-blocking member 120 divides at least part of the accommodating space into a first cavity 111 and a second cavity 112; the detecting member 130 is disposed in the first cavity 111, and the detecting member 130 can detect a characteristic parameter of the object 210 to be detected at the first region of the opening 113; the light emitting member 140 is disposed in the second cavity 112, and the light emitting member 140 can emit light to a second region of the opening 113; the first region is located in the second region, so that the first region detected by the detecting member 130 has the emitted light, thereby improving the brightness of the first region and greatly improving the detection accuracy of the detecting member 130.
As shown in fig. 2, the detecting member 130 is located in the first cavity 111, and the detecting member 130 can detect the characteristic parameters of the object 210 to be detected at the area where the opening 113 is located on the side of the first cavity 111; the light-emitting member 140 is located in the second cavity 112, the light-emitting member 140 can emit light to the object 210 to be detected in the area where the opening 113 is located on the second cavity 112 side, the light-emitting member 140 cannot emit light to the object 210 to be detected in the area where the opening 113 is located on the first cavity 111 side, at this time, only a small amount of light of the light-emitting member 140 enters the area where the opening 113 is located on the first cavity 111 side to illuminate the object 210 to be detected, the light of the area where the opening 113 is located on the first cavity 111 side is insufficient, and the detection accuracy of the detection of the detecting member 130 is low. As an example, the light in the area of the opening 113 on the first cavity 111 side is insufficient, and the amount of light reflected by the surface 5 of the object 210 to be detected on the first cavity 111 side to the detecting member 130 is insufficient, which may cause the induced chromatic aberration of the detecting member 130 to be larger; in particular to
In the case where the surface of the detection object 210 is dark-toned, the color difference Δ E measured in black, deep blue, deep green, etc., is large and unstable. As shown in fig. 1, the first region has the emission light, that is, the entire region of the opening 113 on the side of the first cavity 111 has the emission light, so that the brightness of the first region can be improved, and the detection accuracy of the detection member 130 can be greatly improved.
0 in the embodiment of the present application, the structure of the body 110 is not limited. For example, the body 110 may be a post
A shape structure. For example, the body 110 may have a rectangular parallelepiped structure.
In the embodiment of the present application, the material of the light blocking member 120 is not limited as long as the light blocking member 120 can block light; light cannot pass through the light-blocking member 120. For example, the light blocking member 120 may be a non-transparent structure.
The light-blocking member 120 may be disposed in the receiving space by welding or bonding. The first cavity 1115 and the second cavity 112 may be two completely separated cavities, in which case the first cavity 111 and the second cavity
Body 112 has no connected regions, as shown in FIG. 3. Of course, the first cavity 111 and the second cavity 112 may be separated by a region where the light blocking member 120 is disposed, and a region where the light blocking member 120 is not disposed may communicate with each other, and in this case, there is a region where the first cavity 111 and the second cavity 112 communicate with each other. As an example, as shown in figure 4,
the middle of the first chamber 111 and the middle of the second chamber 112 are partitioned by the light-blocking member 120, and the end of the first chamber 0 111 and the end of the second chamber 112 communicate with each other.
The light blocking member 120 may be located at the middle of the receiving space, and the width of the first cavity 111 and the width of the second cavity 112 may satisfy the equality condition, which means equal or substantially equal. Of course, the light-blocking member 120 may be located at the side close to the light-emitting member 140 in the accommodating space, and the width of the first cavity 111 may be smaller than that of the second cavity
The width of the two cavities 112 is such that the light emitting member 140 emits light more easily to the 5 regions of the opening 113 located at the side of the first cavity 111.
In the embodiment of the present application, the structure of the detecting member 130 is not limited. For example, the detecting member 130 may be a laser ranging sensor. For another example, the detecting member 130 may be a color sensor. Insufficient light affects the detection accuracy of the detecting member 130.
The object 210 to be detected is not limited, and the characteristic parameter is not limited. For example, in the case where the detecting member 130 is a laser ranging sensor, the object to be detected 210 may be an object to be detected in distance, and the characteristic parameter may be distance. For another example, in the case that the detecting member 130 is a color sensor, the object to be detected 210 may be an object to be detected in color, and the characteristic parameter may be a color of the object to be detected 210.
In the embodiment of the present application, the light emitting member 140 may be disposed in the second cavity 112 by welding or bonding. As an example, as shown in fig. 5 and 6, the detection apparatus may further include: the circuit board 160, the circuit board 160 can be fixed in the accommodating space by a screw or a snap structure, and the detecting member 130 and the light emitting member 140 can be soldered to the circuit board 160; the circuit board 160 may be provided with a slot 161, the detecting member 130 and the light emitting member 140 may be located at both sides of the slot 161, and at least a portion of the light blocking member 120 may be caught in the slot 161 to separate the detecting member 130 and the light emitting member 140.
The structure of the light emitting member 140 is not limited as long as it can emit light. For example, the light emitting member 140 may be a light emitting diode LED.
The first region is located in the second region, and the area of the first region may be the same as or different from that of the second region. When the area of a first region is the same as the area of the second region, the first region and the second region satisfy the same condition; the same condition means the same or substantially the same. In the case that the area of the first region is different from the area of the second region, the area of the first region is smaller than the area of the second region, and at this time, the detecting member 130 cannot detect the characteristic parameter of the object 210 to be detected at the region of the opening 113 located at the side of the second cavity 112, as shown in fig. 1.
In some optional implementations of the embodiments of the present application, the area enclosed by the open end surfaces 114 forms an open area B, and the light-shielding member 120 has a projected area a at the open area, as shown in fig. 7; at this time, the opening region B includes: a region of which the opening region is located at the first cavity 111 side, a region of which the opening region is located at the second cavity 112 side, and a projection region a; the region of the open region on the first chamber 111 side and the region of the open region on the second chamber 112 side are located on opposite sides of the projection region a.
In this implementation, the opening end surface 114 refers to an end surface of the body 110 forming the opening 113.
In this implementation, the second region and the opening region may satisfy the same condition. The first region and the opening region may satisfy the same condition, and the first region may also be smaller than the opening region.
In this embodiment, the main optical axis of the light emitting member 140 and the opening region have a first intersection point C, and as shown in fig. 7, the position of the first intersection point C is not limited. For example, as shown in fig. 1 and 7, the first intersection point C may be located at a region where the opening region is located at the side of the second cavity 112; at this time, the main optical axis of the light emitting member 140 may satisfy a vertical condition with respect to the opening region, as shown in fig. 1, the vertical condition being vertical or substantially vertical. Of course, the main optical axis of the light emitting member 140 may be inclined toward the first cavity 111 side so that the first intersection point C is close to the projection area a, as shown in fig. 7, thereby causing the light emitting member 140 to emit light toward an area having an opening area on the first cavity 111 side. For another example, as shown in fig. 8, the first intersection point is located in the projection region a, and at this time, the light emitting member 140 is disposed toward the first cavity 111, and the main light axis of the light emitting member 140 is inclined toward the first cavity 111, so that the light emitting member 140 emits light to a region having an opening region located at the first cavity 111 side. As an example, as shown in fig. 9, the first intersection point is located at the middle of the projection region, so that the light emitting member 140 emits light to the region having the opening region located at the side of the first cavity 111 and the light emitting member 140 emits light to the region having the opening region located at the side of the second cavity 112 substantially the same. For another example, the first intersection point C may be located in a region where the opening region is located at the first cavity 111 side; therefore, the brightness of the object 210 to be detected on the side of the detection piece 130 can be further improved, and the detection accuracy of the detection piece 130 can be improved.
In this implementation, the light shielding member 120 has a first distance D from the opening 113, so that at least part of the edge of the second region intersects with the opening end surface 114 on the first cavity 111 side, as shown in fig. 9 and 1, so that the interference light generated by the position arrangement of the light shielding member 120 and the opening 113 can be prevented from being generated by the position arrangement of at least part of the edge of the second region on the inner wall forming the accommodating space, and the influence of the interference light on the accuracy of the detecting member 130 by the inner wall forming the accommodating space is reduced. Here, the first intersection point may be located at a region where the opening region is located at the side of the second cavity 112, as shown in fig. 1 and 7, or may be located at the projection region, as shown in fig. 8 and 9.
At least a part of the edge of the second region intersects with the opening end surface 114 on the first cavity 111 side, or the whole edge of the second region intersects with the opening end surface 114 on the first cavity 111 side. The implementation manner of intersecting all edges of the second region with the opening end face 114 on the first cavity 111 side is not limited; for example, the shape of the light-blocking member 120 matches the shape of the open end face 114 so that the entire edge of the second region intersects the open end face 114 on the first cavity 111 side; for another example, the shape of the opening end surface 114 matches the shape of the second region, so that the entire edge of the second region intersects the opening end surface 114 on the first cavity 111 side.
In this implementation, the light shielding member 120 has a first distance D from the opening 113, so that at least a part of the edge of the first region intersects with the opening end surface 114 on the side of the second cavity 112, as shown in fig. 9, so that the interference light generated by the position arrangement of the light shielding member 120 and the opening 113 can be prevented from being located on the inner wall forming the accommodating space, and the influence of the interference light on the accuracy of the detecting member 130 by the inner wall forming the accommodating space is reduced; meanwhile, the detection range of the detection member 130 in the opening region can be increased, so that the detection member 130 can detect the characteristic parameters of the object 210 to be detected at all the opening regions.
At least a part of the edge of the first region intersects the opening end surface 114 on the second cavity 112 side, or the whole edge of the first region intersects the opening end surface 114 on the second cavity 112 side. The implementation manner of intersecting all edges of the first region with the opening end surface 114 on the second cavity 112 side is not limited; for example, the shape of the light barrier 120 matches the shape of the open end face 114 so that the entire edge of the first region intersects the open end face 114 on the second cavity 112 side; for another example, the shape of the open end surface 114 matches the shape of the first region such that all edges of the first region intersect the open end surface 114 on the second cavity 112 side.
In some optional implementations of the embodiments of the present application, as shown in fig. 1, the detection apparatus may further include: the light-transmitting member 150 is arranged in the accommodating space, the light-transmitting member 150 is in contact with the light-shielding member 120, and the light-transmitting member 150 forms the end parts of the first cavity 111 and the second cavity 112, so that the first cavity 111 and the second cavity 112 can be blocked by the light-transmitting member 150, and dust is prevented from entering the first cavity 111 and the second cavity 112 to influence the work of the detecting member 130 and the light-emitting member 140; meanwhile, the light emitting member 140 can also emit light through the light transmitting member 150.
In this implementation, the structure of the light-transmitting member 150 is not limited as long as light can pass through the light-transmitting member 150. The light-transmitting member 150 may be a lens. For example, the light-transmitting member 150 may be a glass sheet. For another example, the light-transmitting member 150 may be a plastic sheet.
The thickness of the light-transmitting member 150 may be smaller than the first predetermined value, so that the light-transmitting member 150 is as thin as possible, and the loss of light in the light-transmitting member 150 is reduced.
In this implementation, the main optical axis of the light emitting element 140 has a first incident angle with the light transmitting element 150; the range of the first incident angle is not limited. For example, as shown in fig. 10, the first incident angle i may range from 40 degrees to 45 degrees to prevent the reflectance from increasing and the transmittance from decreasing due to an excessively large first incident angle i; as shown in fig. 11, when the first incident angle i is greater than 45 degrees, the reflectivity of the light-transmitting member 150 increases, and the transmittance decreases, so that most of the emitted light of the light-emitting member 140 is reflected and cannot reach the opening region, which affects the detection accuracy of the detecting member 130. Here, the light emitting member 140 may be disposed toward the first cavity 111 side, and may be capable of making the first intersection closer to a region of the opening 113 corresponding to the first cavity 111 and reducing the reflectance at the first incident angle; here, the light emitting member 140 may be obliquely disposed on the circuit board 160 such that the first intersection is closer to a region of the opening 113 corresponding to the first cavity 111, as shown in fig. 6.
The detection device of the embodiment of the application comprises: a body 110 having an accommodating space and an opening 113; the opening 113 communicates with the accommodating space; a light-blocking member 120 disposed in the accommodating space such that at least a portion of the accommodating space is partitioned into a first cavity 111 and a second cavity 112; the detecting element 130 is disposed in the first cavity 111 and is capable of detecting characteristic parameters of the object 210 to be detected in the first region of the opening 113; a light emitting member 140 disposed in the second cavity 112 and capable of emitting light to a second region of the opening 113; the first region is located in the second region, so that the first region detected by the detecting member 130 has the emitted light, thereby improving the brightness of the first region and greatly improving the detection accuracy of the detecting member 130.
The embodiment of the application also describes an electronic device, which comprises the detection device of the embodiment of the application.
The structure of the electronic device is not limited. For example, the electronic device may be a mobile phone or a computer. As an example, as shown in fig. 12, the electronic device may be a stylus pen, so that the electronic device can both perform touch control and detect characteristic parameters of the object 210 to be detected, and the opening may be disposed at a top end of the stylus pen; under the condition that the characteristic parameter is the color of the object 210 to be detected, the electronic device has a color taking function, and the electronic device is attached to the drawing and the designed and manufactured scene of the user and is more and more popular with the user.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application.
