The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

The following describes the specific structure and imaging process of the imaging device 100 according to the present invention with reference to the drawings.

Referring to fig. 1, fig. 1 is a schematic view of an operating scenario of an imaging device 100 according to the present application. As shown in fig. 1, a light L on the surface of an object a is captured by a lens 140 of the imaging device 100 of the present application, and the light L is incident on the prism 110 through the lens 140 and changes the propagation direction through the prism 110. The light L changes its traveling direction through the prism 110 and then is incident on the image sensor 120, so that the object a is imaged on the image sensor 120.

Referring to fig. 2 and fig. 3, fig. 2 is a schematic structural diagram of an imaging device 100 according to the present application from a side view, and fig. 3 is a schematic exploded structural diagram of the imaging device 100 according to the present application. In the illustration of fig. 2, the imaging device 100 includes a substrate 130, a lens 140, and a housing 150. The substrate 130 and the housing 150 are fixed relative to each other, and the lens 140 is fixed on the housing 150 and directed into the cavity 151 through the housing 150. In the illustration of fig. 3, the substrate 130 and the housing 150 enclose a cavity 151, and the prism 110 and the image sensor 120 are further accommodated in the cavity 151. The image sensor 120 is fixed on the side of the substrate 130 facing the cavity 151, and the prism 110 is fixed relative to the substrate 130.

The lens 140 is fixedly connected to one end of the housing 150 along the second direction 002, and the lens 140 may be directly fixed to the housing 150 or may be fixed to the housing 150 in other manners, which is not limited in this embodiment of the application. Wherein the second direction 002 is the same as the axial direction of the lens 140. In the embodiment shown in fig. 3, the housing 150 includes a lens holder 152, and the lens holder 152 may be integrally formed with the housing 150 or detachably connected to the housing 150, which is not limited in this application. The lens 140 may be fixed relative to the housing 150 by a lens holder 152. Specifically, one end of the lens 140 is inserted into the shaft hole 1521 of the lens holder 152, so that the lens 140 is fixed on the lens holder 152. The other end of the lens 140 is exposed out of the lens holder 152 and faces a side away from the lens holder 152 in a second direction 002 to capture the light L.

The substrate 130 is fixedly disposed at one end of the housing 150 along a third direction 003, as shown in fig. 3, the third direction 003 is perpendicular to the first direction 001 and the second direction 002. The first direction 001 is perpendicular to the propagation direction of the light L inside the prism 110 (see fig. 4). Specifically, the light L is emitted from the light incident surface 111 to the light reflecting surface 113 of the prism 110, and then reflected from the light reflecting surface 113 to the light emitting surface 112, and the light L propagates inside the prism 110 to form two propagation directions. At this time, the first direction 001 needs to be perpendicular to both directions. That is, the two propagation directions of the light L in the prism 110 constitute a plane, and the first direction 001 is perpendicular to the plane. Specifically, the substrate 130 may be a rectangular plate and may be detachably connected to the housing 150, and the application is not particularly limited. In the embodiment shown in fig. 3, the substrate 130 is fixedly attached relative to the housing 150. Specifically, the base plate 130 includes a mounting surface 131, and the mounting surface 131 is a surface of the base plate 130 facing the inner cavity 151. The housing 150 is fixedly attached to the mounting surface 131.

Referring to fig. 3 and 4, fig. 4 is a schematic diagram of an internal structure of the imaging device 100 with the housing 150 removed. As shown in fig. 3 and 4, the prism 110 includes a light incident surface 111, a light emitting surface 112 and a light reflecting surface 113, wherein the light incident surface 111 faces the lens 140, the light emitting surface 112 faces the image sensor 120, and the light reflecting surface 113 is located between the light incident surface 111 and the light emitting surface 112 and forms a certain included angle with the light incident surface 111 and the light emitting surface 112 respectively, so that the light L enters from the light incident surface 111 and then exits from the light emitting surface 112. The light L enters the prism 110 from the light incident surface 111, is reflected by the light reflecting surface 113, and then exits from the light exiting surface 112. The light emitting surface 112 of the prism 110 is attached to the image sensor 120, so that the prism 110 is fixed relative to the substrate 130.

The prism 110 may be a triangular prism, a trapezoidal prism, or other shapes, and the present application is not particularly limited. In the embodiment shown in fig. 3, the prism 110 is a prism, the light incident surface 111 is a side surface of the prism 110 facing the lens 140, the light emitting surface 112 is another side surface of the prism 110 facing the image sensor 120, and the reflection surface 113 is respectively connected to the light incident surface 111 and the light emitting surface 112 and forms a certain included angle with the light incident surface 111 and the light emitting surface 112. Specifically, as shown in fig. 4, the light L captured by the lens 140 is emitted to the light incident surface 111 opposite to the lens 140 through the lens 140, and is vertically emitted into the prism 110 from the light incident surface 111. The light L entering the prism 110 is emitted to the surface of the reflective surface 113, reflected by the reflective surface 113, emitted to the light-emitting surface 112, and finally emitted from the light-emitting surface 112.

In one embodiment, as shown in fig. 4, the light incident surface 111 is vertically connected to the light emitting surface 112. It can be understood that, by arranging the vertical connection between the light incident surface 111 and the light emitting surface 112, the external light can also be emitted from the light emitting surface 112 vertically after entering the light incident surface 111 vertically, so as to further avoid the loss of reflection or refraction when the light propagates in the prism 110, and further ensure the amount of light entering the image sensor 120.

Referring to fig. 3, the image sensor 120 includes an imaging area 121, and the imaging area 121 is used for receiving the light L emitted from the light emitting surface 112. The image sensor 120 is fixedly connected to the substrate 130, and the connection manner between the image sensor 120 and the substrate 130 is not particularly limited in this application. In the embodiment shown in fig. 3, the image sensor 120 is recessed on the substrate 130, such that the surface of the image sensor 120 facing the inner cavity 151 and the mounting surface 131 form a flat plane, and the light emitting surface 112 can be attached to the image sensor 120, or can be attached to a common plane formed by the image sensor 120 and the substrate 130, so that the prism 110 is fixed relative to the substrate 130. In addition, the image sensor 120 faces the cavity 151 and is completely accommodated in the cavity 151.

In one embodiment, the image sensor 120 may be further fixed on the mounting surface 131. At this time, the light exit surface 112 is bonded to the image sensor 120, so that the prism 110 is fixed to the substrate 130.

Further, the light emitting surface 112 of the prism 110 may be attached to the image sensor 120 or the substrate 130, or may be attached to a plane formed by the image sensor 120 and the substrate 130 at the same time, so that the prism 110 is fixed relative to the substrate 130, which is not limited in this application. It can be understood that the light-emitting surface 112 of the prism 110 is attached to the image sensor 120, so that the prism 110 can be fixed relative to the image sensor 120.

In addition, as shown in fig. 3, the inner cavity 151 formed by the housing 150 and the mounting surface 131 of the substrate 130 has a shape adapted to the outer shape structure of the prism 110 so that the prism 110 can be completely accommodated in the housing 150.

In the prior art, the prism 110 is generally fixed inside the terminal 200 (not shown) by a prism bracket or other structures, and in order to avoid the abutting pressure between the prism 110 and the image sensor 120, a preset distance is required between the prism 110 and the image sensor 120 for accommodating the assembly tolerance. The preset distance between the prism 110 and the image sensor 120 is likely to cause the image sensor 120 to be invaded by dust and moisture, which may affect the imaging quality. And a bracket or other structure for fixing the prism 110 is specially provided, so that the structural complexity of the imaging device 100 is increased, and assembly tolerance is easily accumulated, so that the preset distance between the prism 110 and the image sensor 120 is difficult to control, and the imaging quality may be affected. This application is through the laminating of exit surface 112 and image sensor 120 or base plate 130 of prism 110, can reduce the distance between prism 110 and the image sensor 120, eliminates prism 110 and image sensor 120's distance of predetermineeing, avoids external dust and steam to invade image sensor 120, and then causes image sensor 120's damage for imaging quality is not high. Meanwhile, by directly fixing the prism 110 to the image sensor 120 or the substrate 130, a prism holder or a structure separately for fixing the prism 110 is omitted, the structure of the imaging device 100 is further simplified, and assembly tolerances between parts are reduced.

In an embodiment, the prism 110 may be attached to the image sensor 120 or the substrate 130 by glue, shadowless glue, or double-sided glue, and the application does not specifically limit the attaching manner between the prism 110 and the image sensor 120 or the substrate 130. The adhesion between the prism 110 and the image sensor 120 or the substrate 130 can be ensured by glue, shadowless glue or double-sided glue.

Referring to fig. 5, fig. 5 is a schematic structural view of a side view of the prism 110 according to an embodiment. As shown in fig. 5, the light exit surface 112 includes a light exit region 1121, and the light L exits the light exit surface 112 from the light exit region 1121. When the prism 110 is attached to the image sensor 120 or the substrate 130 through the light emitting surface 112, the light emitting area 1121 can completely cover the imaging area 121 of the image sensor 120, so as to improve the utilization rate of the image sensor 120. In this embodiment, when a light-permeable adhesive, such as an optical adhesive or a shadowless adhesive, is used, the adhesive may be further disposed within the light exit region 1121, so that the light exit region 1121 of the prism 110 and the imaging region 121 of the image sensor 120 are attached to each other by the adhesive, and the connection stability between the prism 110 and the image sensor 120 is further improved.

As shown in fig. 5, the prism 110 further includes a fixing portion 114, the fixing portion 114 forms at least one attaching area 1141 on the light-emitting surface 112, and the attaching area 1141 may be rectangular, square, circular or other shapes. In addition, the edge of the attaching region 1141 may coincide with the edge of the light emitting region 1121, or may be spaced from the light emitting region 1121, and the shape and position of the attaching region 1141 are not specifically limited in this application. The prism 110 is fixed with respect to the image sensor 120 by attaching at least one of the attaching regions 1141 to the image sensor 120 or the substrate 130. Furthermore, at least one attaching region 1141 is disposed around the light exit region 1121, so that the light entering the imaging region 121 can be prevented from being shielded by the attaching region 1141, thereby affecting the imaging quality of the image sensor 120. In this embodiment, when a non-transparent adhesive, such as a double-sided tape, is used, the non-transparent adhesive may be located in the attaching region 1141, so that the attaching region 1141 of the fixing portion 114 is attached to the image sensor 120 or the substrate 130, and the prism 110 is fixed to the image sensor 120 without shielding the outgoing light L of the light outgoing region 1121.

In an embodiment, when the non-transparent adhesive is used to attach the attachment region 1141 to the image sensor 120 or the substrate 130, the surface roughness of the attachment region 1141 may be further improved or an uneven structure, such as a wave structure, a sawtooth structure, or a lattice structure, may be additionally disposed on the surface of the attachment region 1141, so as to further increase the contact area between the adhesive and the two opposite surfaces, and improve the connection stability between the attachment region 1141 and the image sensor 120 or the substrate 130.

Further, the fixing portion 114 may be a triangular shape, a triangular pyramid, a trapezoidal shape, or a stepped shape, and the application is not particularly limited. By configuring the fixing portion 114 to have a triangular shape, a triangular pyramid shape, a trapezoidal shape, or the like, the bonding area between the prism 110 and the image sensor 120 or the substrate 130 can be increased without greatly increasing the volume of the prism 110. Specifically, in the embodiment shown in fig. 5, the fixing portion 114 includes a first fixing portion 1142 and a second fixing portion 1143, the first fixing portion 1142 and the second fixing portion 1143 are triangular and respectively arranged at two sides of the light emitting region 1121 along the first direction 001, and the edge of the first fixing portion coincides with the light emitting region 1121.

As shown in fig. 3, the fixing portion 114 is provided with four attaching areas 1141, wherein the first fixing portion 1142 and the second fixing portion 1143 are respectively provided with two attaching areas 1141, the two attaching areas 1141 located on the same side are disposed at a certain distance apart, and the edges of the two attaching areas are overlapped with the light emitting area 1121. The first fixing portion 1142 and the second fixing portion 1143 are bonded to the image sensor 120 or the substrate 130, respectively, so that connection stability between the prism 110 and the image sensor 120 can be further improved.

In one embodiment, the first fixing portion 1142 and the second fixing portion 1143 have a triangular pyramid structure. Specifically, please refer to fig. 6, fig. 6 is a schematic structural diagram of the first fixing portion 1142 and the second fixing portion 1143 being triangular pyramids. As shown in fig. 6, when the first fixing portion 1142 and the second fixing portion 1143 are triangular pyramids, the light incident surface 111 is trapezoidal.

Specifically, referring to fig. 7, fig. 7 is a schematic structural diagram of a stepped structure of the first fixing portion 1142 and the second fixing portion 1143. As shown in fig. 7, when the first fixing portion 1142 and the second fixing portion 1143 are in a step-like structure, the light incident surface 111 is in a convex shape.

In one embodiment, the fixing portion 114 may further include a third fixing portion 1144. Referring to fig. 8, fig. 8 is a schematic structural view of the third fixing portion 1144. The third fixing portion 1144 is located at one side of the prism 110 along the second direction 002, that is, the third fixing portion 1144 may be located at one side of the light incident surface 111 of the prism 110 along the second direction 002, or located at one side of the light reflecting surface 113 of the prism 110. In the embodiment shown in fig. 8, the third fixing portion 1144 is located on the light reflecting surface 113 side of the prism 110 along the second direction 002. By the adhesion of the third fixing portion 1144 to the image sensor 120 or the substrate 130, the adhesion area between the prism 110 and the image sensor 120 is further increased, so that the fixation of the prism 110 with respect to the image sensor 120 is more stable.

In one embodiment, the fixing portion 114 may further include a fourth fixing portion 1145. Referring to fig. 9, fig. 9 is a schematic structural view of the fourth fixing portion 1145. As shown in fig. 9, the fourth fixing portion 1145 is located on the other side of the prism 110 with respect to the third fixing portion 1144 along the second direction 002.
