Referring to fig. 1, fig. 2, fig. 3, fig. 4 and fig. 6, the present invention provides an optical lens assembly 10 applied to a mouse 100.

In an embodiment of the present invention, the optical lens assembly 10 includes a first lens 11, a second lens 13 and a light-condensing portion; the first lens 11 is used for transmitting light rays emitted by the light source 70 of the mouse 100 to the mounting surface 300 on which the mouse 100 is mounted, and the first lens 11 has a first light incident surface 11 a; the second lens 13 is connected to the first lens 11 and is used for transmitting the light reflected by the mounting surface 300 used for mounting the mouse 100 to the optical sensor 90 of the mouse 100; the light condensing part is convexly arranged on the first light incident surface 11a, and the distance between one side of the light condensing part departing from the first light incident surface 11a and the first light incident surface 11a is reduced in a first horizontal direction in which the first lens 11 is far away from the second lens 13; the direction perpendicular to the first lens 11 away from the second lens 13 is defined as a second horizontal direction, and the distance between two opposite sides of the light-condensing portion in the second horizontal direction is reduced in the direction of the light-condensing portion away from the first light incident surface 11 a.

In an embodiment of the present invention, the first lens 11 and the second lens 13 may be disposed in an integral structure. This improves the strength of the joint and reduces the possibility of damage to the joint, thereby extending the useful life of the optical lens assembly 10. Of course, the present application is not limited thereto, and in other embodiments, the first lens 11 and the second lens 13 may be separately configured and detachably connected. Therefore, when one of the two is damaged, the two can be detached for replacement, so that the problem that the whole optical lens assembly 10 needs to be replaced due to local damage is avoided, and the replacement cost of the optical lens assembly 10 is reduced. Specifically, the first lens 11 and the second lens 13 may be fixed by a snap connection or a magnetic attraction. In addition, the mounting surface 300 on which the mouse 100 is mounted is a plane for supporting the mouse 100, for example: a desktop or surface light of the mouse 100 pad.

The first lens 11 may transmit the light to the mounting surface 300 on which the mouse 100 is mounted, and may transmit the light into the second lens 13 by reflection from the mounting surface 300 on which the mouse 100 is mounted. The second lens 13 can transmit the light to the optical sensor 90 for imaging, so that the mouse 100 can determine the moving direction and the moving distance of the mouse 100 by analyzing the position change of the feature point on the image, thereby completing the positioning process of the mouse 100. Because the optical lens in this scheme still includes the spotlight portion, the first income plain noodles 11a is located to the spotlight portion arch, and on the direction that first lens 11 kept away from second lens 13, the distance that the spotlight portion deviates from between one side of first income plain noodles 11a and the first income plain noodles 11a is the reduction setting. Therefore, the light emitted by the light source 70 of the mouse 100 can be transmitted towards the direction close to the second lens 13 through the refraction of the light-gathering part, and the possibility of light waste caused by the transmission of the light emitted by the light source 70 of the mouse 100 towards the direction far away from the second lens 13 is reduced. That is, the utilization rate of the light emitted by the light source 70 is increased, and the definition of the track image shot by the optical mouse 100 in the moving process is enhanced, so that the positioning accuracy of the mouse 100 in the positioning process is improved. And, define the direction perpendicular to first lens 11 and far away from second lens 13 as the second horizontal direction, in the direction that the light concentration portion deviates from first income light face 11a, the distance between the relative both sides of light concentration portion on the second horizontal direction is setting up for reducing. So make the light that light source 70 sent pass through the spotlight portion and can be the trend that is close to each other after the refraction of the relative both sides on the second horizontal direction, also realized the gathering of light promptly, strengthened the light intensity that gets into in the first lens 11 through having reduced light because the light energy loss that the diffusion transmission caused. So that the utilization rate of the light emitted by the light source 70 can be further increased, thereby further improving the positioning accuracy of the mouse 100 in the positioning process.

Referring to fig. 2 and 4, in an embodiment of the present invention, the projection of the light-condensing portion is disposed in an arch shape or a triangle shape on the projection plane parallel to the second horizontal direction.

It can be understood that the projection of spotlight portion is the arch form and can make spotlight portion be an cambered surface and with the machined surface looks adaptation of cutter, so be convenient for the cutter to its direct machining or process its forming die to the complexity of the processing of spotlight portion can be reduced. When the projection of spotlight portion was the triangle-shaped setting, can be so that the volume of spotlight portion is less relatively, so reduced the material that this spotlight portion of production will use to the manufacturing cost of spotlight portion has been reduced.

In an embodiment of the present invention, the light-gathering portion and the first lens 11 are integrally formed.

It can be understood that, the arrangement makes the connection between the light-gathering portion and the first lens 11 more stable, and reduces the possibility of the light-gathering portion and the first lens 11 being separated from each other, so that the light-gathering portion is stably fixed to the first light incident surface 11a of the first lens 11. Meanwhile, the arrangement avoids the influence on the transmission path of the light because the connection structure is arranged between the light source and the light receiver, thereby ensuring the light condensation effect of the light condensation part.

In an embodiment of the present invention, the first lens 11 has a light source accommodating base 111 protruding from the first light incident surface 11a, and the light source accommodating base 111 is disposed around the light-condensing portion.

It can be appreciated that the light source receiving platform 111 is annular and can be used to receive the light source 70 of the mouse 100 to make the installation thereof more compact, thereby reducing the overall size of the mouse 100 and reducing the space occupation. When a part of the light emitted from the light source 70 is transmitted to the inner wall of the light source accommodating table 111, the inner wall of the light source accommodating table 111 may reflect the part of the light and transmit the part of the light to the light condensing portion. Thus, the energy loss of the light source 70 caused by light diffusion can be reduced, thereby further improving the utilization rate of light and improving the positioning accuracy of the mouse 100 in the positioning process. The light source receiving table 111 may have a square configuration or a circular configuration, but the present application is not limited thereto and may have the same shape as the light source 70 of the mouse 100.

Referring to fig. 2 and fig. 3, in an embodiment of the present invention, the first lens 11 further includes a first light emitting surface 11b, a first reflecting surface 11c and a second reflecting surface 11d, the first light emitting surface 11b and the first light incident surface 11a are oppositely disposed, the first reflecting surface 11c and the second reflecting surface 11d are both connected to the first light incident surface 11a and the first light emitting surface 11b, the first reflecting surface 11c and the second reflecting surface 11d are oppositely disposed, the light emitted from the light source 70 sequentially passes through the first light incident surface 11a, the first reflecting surface 11c, the second reflecting surface 11d and the first light emitting surface 11b, and the second lens 13 is connected to the second reflecting surface 11 d.

It can be understood that, the structure of the first lens 11 is arranged such that the light emitted by the light source 70 enters the first lens 11 through the first light incident surface 11a, then sequentially passes through the first reflection surface 11c and the second reflection surface to reflect the light so as to change the transmission path of the light, and is refracted to the mounting surface 300 used for mounting the mouse 100 through the first light emitting surface 11b, and finally the light can be accurately transmitted to the second lens 13 through the reflection of the mounting surface 300 used for mounting the mouse 100, and is accurately transmitted to the optical sensor 90 of the mouse 100 through the second lens 13, thereby completing the transmission process of the light. Since the light transmission path is short, the light energy lost during the transmission process of the light can be reduced to further improve the utilization efficiency of the light, and the structure of the first lens 11 can be simple. Of course, the present application is not limited thereto, and in other embodiments, the first lens 11 may further have a third reflecting surface or a fourth reflecting surface, etc. so that the transmission distance of the light ray in the direction of approaching the second lens 13 of the first lens 11 can be increased under more reflections of the light ray by the first reflecting surface 11c, the second reflecting surface 11d, and the third reflecting surface or the fourth reflecting surface.

In an embodiment of the present invention, the first reflective surface 11c is recessed toward the second reflective surface 11d to form a curved surface or two walls disposed at an included angle.

It can be understood that the arrangement makes the first reflecting surface 11c have a condensing effect on the light, so that the energy loss of the light caused by diffusion and transmission in the transmission process is reduced, more light can be transmitted to the second reflecting surface 11d after being reflected by the first reflecting surface 11c, and the light condensing performance of the first lens 11 is improved.

In an embodiment of the present invention, the second reflective surface 11d is recessed toward the first reflective surface 11c to form a curved surface or two walls disposed at an included angle.

It can be understood that, by such an arrangement, the second reflecting surface 11d also has a condensing effect on the light, so as to further reduce the energy loss caused by diffusion and transmission of the light during transmission, so that more light can be transmitted to the first light emitting surface 11b after being reflected by the second reflecting surface 11d, thereby further improving the light condensing performance of the first lens 11.

In an embodiment of the present invention, in the first horizontal direction, the distance between the first light emitting surface 11b and the first light incident surface 11a is in a decreasing setting.

It can be understood that, the arrangement is such that the light is refracted by the first light emitting surface 11b and transmitted toward the direction close to the second lens 13, so as to further reduce the possibility of light waste caused by the transmission of the light emitted by the light source 70 of the mouse 100 toward the direction away from the second lens 13, that is, further increase the utilization rate of the light.

In an embodiment of the present invention, the second lens 13 has a second light incident surface 13a and a second light emitting surface 13b which are disposed oppositely, a direction of the second light incident surface 13a facing the second light emitting surface 13b is perpendicular to a direction of the first lens 11 away from the second lens 13, and light reflected by the mounting surface 300 for mounting the mouse 100 passes through the second light incident surface 13a and the second light emitting surface 13b in sequence.

It is understood that the second lens 13 is disposed parallel to the mounting surface 300 on which the mouse 100 is mounted, so that the light reflected by the mounting surface 300 on which the mouse 100 is mounted is transmitted to the second lens 13. In this case, the second lens 13 may be directly connected to the second reflecting surface 11d of the first lens 11 through the second light incident surface 13a, or may be indirectly connected to the second reflecting surface 11d of the first lens 11 through a connecting block. In addition, it should be noted that, in other embodiments, the second lens 13 may further include a fifth reflecting surface or a sixth reflecting surface, so that after the light reflected by the mounting surface 300 used for mounting the mouse 100 enters the second lens 13 through the second light incident surface 13a, the light transmission path may be changed through the fifth reflecting surface or the sixth reflecting surface, so that the optical sensor 90 of the mouse 100 may be disposed at different positions and still receive the light refracted by the second light emitting surface 13 b.

In an embodiment of the present invention, the second light incident surface 13a is recessed toward the second light emitting surface 13b to form a curved surface or two walls disposed at an included angle; and/or the second light emitting surface 13b is concavely arranged towards the second light incident surface 13a to form an arc surface or concavely arranged to form two wall surfaces arranged at an included angle

It can be understood that, with such an arrangement, the light reflected by the mounting surface 300 on which the mouse 100 is mounted and used can reduce the included angle formed with the vertical direction after being refracted twice by the second light incident surface 13a and the second light emitting surface 13b, that is, more light can be emitted more forward to the optical sensor 90 of the mouse 100, so that the optical sensor 90 can shoot and image the light. Since the optical sensor 90 of the mouse 100 captures and images light as a prior art, the operation of the optical sensor 90 will not be described in detail.

In an embodiment of the present invention, the second lens 13 is convexly provided with a sensor accommodating base 131, and the sensor accommodating base 131 is disposed around the second light emitting surface 13 b.

It will be appreciated that the sensor receiving platform 131 is annular and may be used to receive the optical sensor 90 of the mouse 100 to make the installation thereof more compact, thereby further reducing the overall size of the mouse 100 and reducing the space occupied thereby. When a part of the light emitted from the second light emitting surface 13b is transmitted to the inner wall of the sensor accommodating table 131, the inner wall of the sensor accommodating table 131 can reflect the part of the light and transmit the part of the light to the optical sensor 90. Thus, the energy loss of the light source 70 caused by light diffusion can be reduced, thereby further improving the utilization rate of light and improving the positioning accuracy of the mouse 100 in the positioning process. The sensor housing table 131 may have a square configuration or a circular configuration, but the present application is not limited thereto and may have the same shape as the optical sensor 90 of the mouse 100.

It will be appreciated that bonding the light source 70 to the side of the circuit board 50 facing the optical lens allows the light source 70 and the first lens 11 to be closer together, thereby reducing energy loss by shortening the light transmission path. The light source 70 is adhered to the circuit board 50 to ensure the stability of the connection between the two; the circuit board 50 does not need a connecting structure for fixing the circuit board, so that the influence of the arrangement of the connecting structure on the structure of the circuit board 50 can be avoided. Specifically, the light source 70 may be accommodated in the light source accommodating stage 111 of the first projector, and the optical sensor 90 may be partially embedded in the sensor accommodating stage 131 of the second lens 13, so as to reduce the overall volume of the mouse 100.
