When the distance sensing module is assembled on the smart terminal, the cover plate 60 covers the top of the light guide post 40, the light hole 61 corresponds to the second light transmission surface 412, and the housing 70 surrounds the main board 30 and the light guide post 40.

In the embodiment, the connecting portion 42 is disposed between the first light-transmitting surface 411 and the second light-transmitting surface 412 of the light guide bar 40, and a light transmission path is still formed between the first light-transmitting surface 411 and the second light-transmitting surface 412, so that the light guide bar 40 is substantially in a Z shape rotated by 90 ° when viewed from the side, when the side where the first light-transmitting surface 411 of the light guide bar 40 is located is fixed on the motherboard 30, the second light-transmitting surface 412 is further shifted to the outer side (right side in fig. 3) of the motherboard 30, in other words, the end where the first light-transmitting surface 411 is located is shifted to the middle (left side in fig. 3) of the motherboard 30 relative to the second light-transmitting surface 412 and the light-transmitting hole 61 of the cover plate 60. The structure enables the light distance sensor 50, the light guide pillar 40 and the light holes 61 of the cover plate 60 to meet the light path required by the light distance sensor 50 without aligning along the direction perpendicular to the main board 30 when the light distance sensing module is assembled on the intelligent terminal, so that the main board 30 does not need to protrude outwards for a part, or the distance of the main board 30 protruding outwards is reduced, the supporting position of the light guide pillar 40 can be provided, the area of the main board 30 is reduced, and the cost is reduced; meanwhile, since the main board 30 does not need to be provided with the protruding portion, the first light-transmitting surface 411 is also offset toward the middle of the main board 30 relative to the second light-transmitting surface 412, that is, the thinning degree of the housing 70 is smaller than that in the prior art, which is beneficial to ensuring the waterproof and strength performance.

Alternatively, as shown in fig. 3, in the present embodiment, a first reflection surface 421 and a second reflection surface 422 are formed on the connection portion 42 to be opposite to each other. The light beam incident from the first light-transmitting surface 411 passes through the first reflecting surface 421 and the second reflecting surface 422, and then exits from the second light-transmitting surface 412; the light beam incident from the second light-transmitting surface 412 passes through the second reflecting surface 422 and the first reflecting surface 421, and then exits from the first light-transmitting surface 411.

Optionally, as shown in fig. 3, in the present embodiment, the planes of the first reflective surface 421 and the second reflective surface 422 and the planes of the first light-transmitting surface 411 and the second light-transmitting surface 412 form an included angle, and more specifically, the first light-transmitting surface 411 and the second light-transmitting surface 412 are parallel to each other, the first reflective surface 421 and the second reflective surface 422 are parallel to each other, the included angle between the first reflective surface 421 and the first light-transmitting surface 411, and the included angle between the second reflective surface 422 and the second light-transmitting surface 412 are 45 °.

Further, the light guide pillar 40 further includes an extension portion 43, one end of the extension portion 43 is connected to the upper portion of the connection portion 42, the other end extends upward along the vertical direction, and the second light-transmitting surface 412 is formed on one end of the extension portion 43 away from the connection portion 42. By the arrangement of the extension portion 43, the distance between the first light-transmitting surface 411 and the second light-transmitting surface 412 can be adjusted in the Z direction, so that the optical distance sensing module does not receive interference from the thickness of the components between the cover plate 60 and the main board 30, such as the display module.

It can be understood that the light-exiting light guide pillar 45 or the light-entering light guide pillar 46 has the first light-transmitting surface 411, the second light-transmitting surface 412, the connecting portion 42, the extending portion 43, and the like. As shown in fig. 3, when the light emitting unit 51 emits light, the light enters the light guide pillar 45 through the first light transmitting surface 411 of the light guide pillar 45, and is reflected by the first reflecting surface 421 and the second reflecting surface 422, and then is emitted from the second light transmitting surface 412 of the light guide pillar 45; when the reflected light enters the light guiding column 46 through the second transparent surface 412 of the light guiding column 46, the light is reflected by the second reflecting surface 422 and the first reflecting surface 421, and then exits through the first transparent surface 411 of the light guiding column 46 and enters the light receiving unit 52.

Alternatively, as shown in fig. 3, 10 and 11, a gap is formed between the light exit guide pillar 45 and the light entrance guide pillar 46, and a partition plate 71 is provided in the gap to prevent the light beams from interfering with each other.
