[0043] In an embodiment, the first lens 20 and the second lens 40 enclose a containing space 30, and the emission lens 60 partially penetrates the through -going part 50 and extends into the containing space 30.

[0044] As Figure 1 As shown, it can be understood that the given space between the first lens 20 and the second lens 40 is the containing space 30, and the emission lens 60 partially penetrates the through -going part 50 and extends into the containing space 30.

[0045] It can be understood that part of the emission lens 60 is arranged in the containing space 30, which rationally utilizes the space between the first lens 20 and the second lens 40, avoids the idle of the containing space 30, and improves the utilization rate of the space in the receiving lens 10.

[0046] It can be understood that the emission lens 60 is arranged on the side of the second lens 40 facing the first lens 20, and the first focusing of the second lens 40 avoids the influence of the emission lens 60 on the reception of light, improving the accuracy of distance measurement.

[0047] In an embodiment, the receiving lens 10 further comprises a first housing 11, and the first lens 20 and the second lens 40 are arranged in the first housing 11.

[0048] The emission lens 60 comprises a second housing 61.

[0049] The second housing 61 partially penetrates the through -going part 50 and extends into the containing space 30, and the second housing 61 is connected with the first housing 11.

[0050] In order to facilitate the installation of the lens, the first shell 11 is connected with the second shell 61, so as to reduce the difficulty of installing the transmitting lens 60 in the receiving lens 10.

[0051] Further, in order to facilitate the connection between the first shell 11 and the second shell 61, the second shell 61 is arranged close to the inner wall of the first shell 11, that is, the second shell 61 is away from the axis of the first shell 11, so as to facilitate the direct connection between the second shell 61 and the inner wall of the first shell 11, and reduce the influence of the transmitting lens 60 on the light receiving efficiency of the receiving lens 10, and improve the accuracy of distance measurement.

[0052] As shown in Figure 2 The second shell 61 is arranged close to the inner wall of the first shell 11, so that the through portion 50 on the first lens 20 is away from the center of the first lens 20, thereby facilitating the penetration of the second shell 61, and the second shell 61 is away from the focal point of the first lens 20, avoiding affecting the focusing of the first lens 20.

[0053] In an embodiment, in order to facilitate the connection between the second shell 61 and the first shell 11, a connecting portion is connected between the second shell 61 and the first shell 11, so as to facilitate the connection and assembly between the first shell 61 and the first shell 11.

[0054] In an embodiment, the second shell 61 and the first shell 11 are integrally formed.

[0055] In order to reduce the assembly difficulty of the second shell 61 in the first shell 11, the first shell 11 and the second shell 61 are integrally formed, and the assembly connection between the first shell 11 and the second shell 61 is omitted.

[0056] In an embodiment, the vertical cross section of the first shell 11 connected with the first lens 20 is smaller than the vertical cross section of the first shell 11 connected with the second lens 40.

[0057] In order to maximize the aperture of the receiving lens 10 in a given space, the vertical cross section of the first shell 11 connected with the first lens 20 is smaller than the vertical cross section of the first shell 11 connected with the second lens 40.

[0058] It is understood that the area of ​​the first lens 20 is smaller than the area of ​​the second lens 40, and the second lens 40 is located on the side of the transmitting lens 60 away from the first lens 20. Thus, the second lens 40 preferentially receives reflected light, and the large area of ​​the second lens 40 can receive as much reflected light as possible and achieve light focusing, so that the second lens can further focus the light on the photosensitive surface for accurate measurement.

[0059] In one embodiment, the portion of the side of the first housing 11 surrounding the second housing 61 within the receiving space that is away from the second housing 61 is tilted toward the first lens 20.

[0060] like Figure 1 As shown, the second housing 61 is disposed on the side of the inner wall of the first housing 11, and the portion of the first housing 11 between the first lens 20 and the second lens 40 that is away from the second housing 61 is inclined and tilted toward the direction of the first lens 20.

[0061] It is understandable that by tapering the first housing 11 in the extending direction of the first housing 11, the first housing 11 can be fitted to the first lens 20 and the second lens 40, and the volume of the first housing 11 can be reduced, thereby reducing the space occupied by the rangefinder.

[0062] In one embodiment, the first housing 11 includes a first housing portion 111, a second housing portion 112, and a third housing portion 113. The first housing portion 111 and the third housing portion 113 are both hollow and disposed on the same plane. The vertical cross-section of the first housing portion 111 is larger than the vertical cross-section of the third housing portion 113. The second housing portion 112 is connected to the side of the first housing portion 111 and extends obliquely toward the side of the third housing portion 113.

[0063] like Figure 1 As shown, the first shell portion 111 is used to enclose the second lens 40, the third shell portion 113 is used to enclose the first lens 20, and the second shell portion 112 is arranged around the receiving space.

[0064] It is understandable that by arranging the first shell 111, the second shell 112, and the third shell 113 in a gradually decreasing manner, the aperture of the receiving lens can be maximized to improve the ranging capability of the rangefinder, while also reducing the size of the rangefinder's outer contour, saving space, and facilitating user adaptation and installation.

[0065] In an embodiment, the first shell part 111 and the third shell part 113 are arranged on the same plane as a base surface, and the emission lens is arranged close to the base surface.

[0066] In order to facilitate the connection or integration between the first shell 11 and the second shell 61, as shown, the first shell part 111 close to the emission lens 60, the second shell part 112 close to the emission lens 60, and the third shell part 113 close to the emission lens 60 are all arranged on the same plane. Figure 1

[0067] It can be understood that the part of the first shell 11 connecting the second shell 61 is arranged in a straight line along the extension direction of the first shell 11 to ensure the stability of the connection between the second shell 61 and the first shell 11, and to avoid the influence of the emission lens 60 on the reception of light by the first lens 20 due to the inclined second shell part 112, which is beneficial to improve the accuracy of distance measurement.

[0068] In an embodiment, the first lens 20 and the second lens 40 are both arranged close to the second shell part 112.

[0069] It can be understood that the first lens 20 and the second lens 40 are arranged on opposite sides of the second shell part 112, so as to minimize the size of the accommodation space as much as possible while ensuring the collection of light by the first lens 20 to the second lens 40. In the case of arranging the emission lens 60 part in the accommodation space 30, the size of the first shell 11 is reduced by reducing the size of the accommodation space, thereby reducing the occupied space of the distance measuring instrument, avoiding excessive space limitation in the assembly process due to the excessive size of the first shell 11, and improving the user's experience.

[0070] The utility model also proposes a kind of laser range finder, the laser range finder includes the lens integrated structure, the specific structure of the lens integrated structure refers to above embodiment, since the laser range finder of the present application adopts all technical solutions of above all embodiments, at least has all beneficial effects brought by the technical solutions of above embodiments, here no longer one by one elaboration.

[0071] The above is only exemplary embodiment of the utility model, and not therefore limit the patent range of the utility model, any equivalent structural transformation made by using the utility model specification and drawing contents, or direct / indirect application in other related technical fields are included in the patent protection range of the utility model.​
