DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1 to Figure 4 The short-distance sensor shown in the figure comprises a substrate 1, and circular grooves 4 are formed at both ends of the top of the substrate 1, and a transmitting component 5 and a receiving component 15 are respectively installed inside the two circular grooves 4. The transmitting component 5 is used to transmit a light signal, and the receiving component 15 senses an object by receiving the light signal reflected by the object.

[0024] The outside of the substrate 1 is plugged with a light shielding frame 3, which is fixedly connected to the substrate 1 by screws 14. The light shielding frame 3 can be made of, but not limited to, epoxy resin material, and has a light shielding effect.

[0025] In order to improve the stability of the transmitting component 5 and the receiving component 15 in use and prevent vibration damage due to bumps, an airbag ring 6 is fixedly connected to the inside of the circular groove 4, and the two airbag rings 6 respectively surround the outside of the transmitting component 5 and the receiving component 15. When the airbag ring 6 expands and becomes larger, it will adaptively abut against the outside of the bottom of the transmitting component 5 or the receiving component 15, thereby improving the stability of the transmitting component 5 and the receiving component 15 in use.

[0026] A shading plate 9 is provided between the transmitting component 5 and the receiving component 15. The shading plate 9 is integrally formed on the substrate 1. The shading plate 9 may be made of, but not limited to, epoxy resin material and has a shading effect.

[0027] In order to improve the shading effect, a second square groove 10 is provided on the upper surface of the shading plate 9, and a slide plate 11 is slidably connected inside the second square groove 10. First square grooves 7 are provided at both ends of the substrate 1, and the two first square grooves 7 are connected to the second square groove 10. The airbag ring 6 is connected to the corresponding first square groove 7 through the flow channel 8, and a shading agent is filled between the second square groove 10 and the two first square grooves 7. The shading agent is a substance used to shade or block light to prevent light signal interference between the transmitting component 5 and the receiving component 15.

[0028] A sealing assembly for squeezing the slide plate 11 is disposed above the substrate 1. The sealing assembly includes a light-transmitting member 2 and a pressing plate 13. The light-transmitting member 2 is fixedly connected to the top of the light-shielding frame 3. The light-transmitting member 2 and the light-shielding frame 3 are an integrated structure. The light-transmitting member 2 can be made of, but not limited to, glass. The pressing plate 13 is fixedly connected to the bottom of the light-transmitting member 2. The pressing plate 13 is inserted into the inside of the second square groove 10 and abuts against the slide plate 11.

[0029] Specifically, the transmitting component 5 is used to transmit a light signal to the outside of the light-transmitting member 2 , and the receiving component 15 senses the object by receiving the light signal reflected by the object outside the light-transmitting member 2 .

[0030] A spring 12 is disposed inside the second square groove 10 . One end of the spring 12 is fixedly connected to the slide plate 11 , and the other end of the spring 12 is fixedly connected to the inner wall of the second square groove 10 .

[0031] During operation, the pressure plate 13 is inserted into the second square groove 10 and abuts against the slide plate 11, forcing the slide plate 11 to slide downward, and the spring 12 contracts. The downward sliding of the slide plate 11 will cause the sunscreen to flow into the airbag rings 6 on both sides, and adaptively abut against the outer sides of the bottoms of the emitting component 5 and the receiving component 15, respectively, to improve the stability of the use of the emitting component 5 and the receiving component 15.

[0032] At the same time, the sunshade cooperates with the sunshade plate 9 to provide double protection, thereby improving the sunshade effect and preventing optical signal interference between the transmitting component 5 and the receiving component 15.

[0033] Furthermore, the plug-in fit between the pressure plate 13 and the second square groove 10 forms a connected whole that is not easily deformed, and can also improve the accuracy and convenience of the installation of the proximity sensor.

[0034] Furthermore, when the transmitting component 5 and the receiving component 15 need to be inspected, the screw 14 is removed, and the restoring elastic force of the spring 12 causes the light-transmitting component 2 to spring upward, and the light-transmitting component 2, the light-shielding frame 3 and the substrate 1 are quickly separated, thereby improving the efficiency of the inspection.

[0035] At the same time, when the light-transmitting member 2 pops up, the slide plate 11 slides upward, and the sunshade inside the airbag ring 6 flows back to the inside of the second square groove 10 and the first square groove 7, making it easy to remove the transmitting component 5 or the receiving component 15.

[0036] The utility model also includes an electronic device, which uses the above-mentioned proximity sensor. The electronic device can be a wearable device, a smart phone, a smart home, a smart car and other devices.
