Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sensor technology and relates to a sealed transceiver. Background Technology
[0002] A sensor is a detection device that can sense the information being measured and transform that information into an electrical signal or other required form of information output according to certain rules, so as to meet the requirements of information transmission, processing, storage, display, recording and control. The characteristics of sensors include miniaturization, digitization, intelligence, multi-functionality, systematization and networking. It is the primary link in realizing automatic detection and automatic control. The existence and development of sensors have given objects senses such as touch, taste and smell, making objects gradually come alive.
[0003] Traditional methods for sealing and encapsulating existing sensor products typically involve either snap-fit assembly or adhesive dispensing. Both methods present two main problems. Snap-fit assembly, while providing a secure connection between plastic parts, fails to achieve the required IP67 airtightness and waterproof rating during sensor use. Adhesive dispensing, on the other hand, relies heavily on the adhesive material and environmental conditions to ensure IP67 airtightness. The adhesive's performance can also be affected by environmental factors and aging, leading to poor airtightness and waterproofing. Furthermore, due to the small size of the product, the dispensing cycle time (CT) is 8 seconds, and issues like dispensing instability and adhesive overflow can occur, increasing adhesive costs and resulting in wasted processing resources.
[0004] Therefore, there is an urgent need in the field for a sealed transceiver to solve the above-mentioned technical problems. Utility Model Content

[0031] Please refer to Figures 1-4One embodiment of this utility model provides a sealed transceiver to solve the problems of existing products being unable to achieve airtight and waterproof ratings and the high manufacturing costs of CT dispensing processes and adhesive materials.
[0032] Specifically, please refer to Figure 1 A perspective view of a sealed transceiver provided in an embodiment of this utility model. Figure 2 This is an exploded view of a sealed transceiver provided by an embodiment of the present invention. The present invention provides a sealed transceiver, including: a transceiver body 10, a cover plate 20, and a sealing fit structure 30 connecting the transceiver body 10 and the cover plate 20. By setting the sealing fit structure 30 to connect the transceiver body 10 and the cover plate 20, a tight connection between the transceiver body 10 and the cover plate 20 is achieved. The sealing fit structure 30 can prevent dust, rainwater, etc. from entering the transceiver, achieving IP67 level protection, protecting the internal electronic components from dust contamination, and enabling normal operation under harsh environmental conditions (such as rain, snow, and humidity). The cover plate 20 and the sealing structure provide additional physical protection for the internal components, preventing damage to the internal components from external impacts and vibrations.
[0033] Specifically, the sealing structure 30 includes a first toothed structure 31 disposed on the transceiver body 10 and a second toothed structure 32 disposed on the cover plate 20. The first toothed structure 31 is disposed facing the cover plate 20, and the second toothed structure 32 is disposed corresponding to the first toothed structure 31. The first toothed structure 31 and the second toothed structure 32 are connected to each other in a cooperative manner. By setting the sealing mating structure 30, which includes a first toothed structure 31 on the transceiver body 10 and a second toothed structure 32 on the cover plate 20, the design of the toothed structure with the first toothed structure 31 and the second toothed structure 32 engaging with each other can form multiple sealing lines, increasing the effective sealing area and thus improving the overall sealing performance. The first toothed structure 31 and the second toothed structure 32 can quickly mesh, ensuring the positional accuracy of the cover plate 20 and the body during installation, avoiding misalignment problems, achieving a fast and firm connection, increasing the mechanical strength of the connection part, improving the durability of the equipment under external impact and vibration, and also saving on the manufacturing cost of CT and the cost of adhesive materials in the dispensing process.
[0034] As a further improvement of this utility model, the first toothed structure 31 and the second toothed structure 32 are ultrasonically welded to form the sealing fit structure 30. By setting the first toothed structure 31 and the second toothed structure 32 to form the sealing fit structure 30 through ultrasonic welding, the first toothed structure 31 and the second toothed structure 32 form a seamless connection, effectively preventing the ingress of moisture, dust and other impurities, achieving a very high sealing level (such as IP67 or higher). At the same time, the connection formed by ultrasonic welding is very stable and not easily affected by environmental factors, maintaining good sealing performance for a long time. Compared with the existing technology of assembly by dispensing, ultrasonic welding of the first toothed structure 31 and the second toothed structure 32 does not require additional materials, reducing costs and complexity. Compared with other welding methods, ultrasonic welding does not use solvents or harmful chemicals during the process, making it environmentally friendly and in line with the requirements of sustainable development.
[0035] As a further improvement to this utility model, please refer to Figure 3 The transceiver body 10 has a cavity 11 facing the cover plate 20. The cavity 11 includes a first cavity 111 and a second cavity 112. The bottom of the first cavity 111 has a transmitting hole 1111 and a first lens is placed inside the first cavity 111. The bottom of the second cavity 112 has a receiving hole 1121 and a second lens is placed inside the second cavity 112. The transceiver body 10 is provided with a cavity 11 facing the cover plate 20. The cavity 11 includes a first cavity 111 and a second cavity 112. The first cavity 111 and the second cavity 112 can be independently designed and adjusted to adapt to the optical characteristics of different lenses. Preferably, the first cavity 111 contains a first lens, and the second cavity 112 contains a second lens. The first lens in the first cavity 111 forms a transmitting optical path through the transmitting aperture 1111, and the first lens is used to diverge the light beam on the transmitting optical path. The second lens in the second cavity 112 forms a receiving optical path through the receiving aperture 1121, and the second lens is used to converge the light beam on the receiving optical path. The transmitting and receiving optical paths in the first cavity 111 and the second cavity 112 cooperate to achieve distance detection. The design of the first cavity 111 and the second cavity 112 provides physical isolation, protecting each lens from external impacts and vibrations, and improving the overall stability of the sealed transceiver.
[0036] As a further improvement of this utility model, the sealed transceiver also includes a fixing member 40. The fixing member 40 is provided with a first fixing cylinder 41 and a second fixing cylinder 42. The first fixing cylinder 41 is connected to the first cavity 111, and the second fixing cylinder 42 is connected to the second cavity 112. By setting the fixing member 40 to include the first fixing cylinder 41 and the second fixing cylinder 42, and connecting the first fixing cylinder 41 and the second fixing cylinder 42 to the first cavity 111 and the second cavity 112 respectively, additional mechanical support can be provided for the first lens and the second lens in the first cavity 111 and the second cavity 112, enhancing the rigidity and stability of the entire transceiver, effectively reducing the influence of external vibration on the internal lenses, and ensuring the stability and accuracy of the optical system. At the same time, the fixing member 40 connects the first cavity 111 and the second cavity 112 through the first fixing cylinder 41 and the second fixing cylinder 42 respectively, which can better isolate the transmitting optical path and the receiving optical path, reduce mutual interference between optical paths, and improve the detection accuracy of the sealed transceiver.
[0037] As a further improvement of this utility model, the side wall of the fixing member 40 is provided with a first snap-fit structure 43, and the transceiver body 10 is provided with a second snap-fit structure 12 corresponding to the first snap-fit structure 43. The first snap-fit structure 43 and the second snap-fit structure 12 cooperate to connect the fixing member 40 and the transceiver body 10. By providing the first snap-fit structure 43 on the side wall of the fixing member 40 and the second snap-fit structure 12 corresponding to the first snap-fit structure 43 on the transceiver body 10, the first snap-fit structure 43 and the second snap-fit structure 12 cooperate to connect the fixing member 40 and the transceiver body 10, ensuring a reliable connection between the fixing member 40 and the transceiver body 10, avoiding loosening or separation between the fixing member 40 and the transceiver body 10. The snap-fit structure can effectively reduce the influence of external vibration on the internal lens, ensure the stability and accuracy of the optical system, and enhance the rigidity and stability of the sealed transceiver.
[0038] As a further improvement of this utility model, a fixing groove 421 is provided on the second fixing cylinder 42, and a filter plate 422 is provided in the fixing groove 421. By providing a fixing groove 421 on the second fixing cylinder 42 and providing a filter plate 422 in the fixing groove 421, the installation stability of the filter plate 422 is ensured. The fixing groove 421 provides physical isolation for the filter plate 422, protecting it from the effects of external impact and vibration. The filter plate 422 can effectively reduce stray light and background noise, improve the signal-to-noise ratio of the transceiver, and thus improve the stability and reliability of the sealed transceiver in complex environments.
[0039] As a further improvement of this utility model, by circumferentially disposing the first toothed structure 31 around the cavity 11, the first toothed structure 31 can form multiple sealing lines at the connection, further improving the overall sealing performance and preventing moisture, dust and other impurities from entering the cavity 11.
[0040] As a further improvement to this utility model, please refer to Figure 4 The first toothed structure 31 includes a plurality of interconnected first teeth 311, and the second toothed structure 32 includes a plurality of interconnected second teeth 321. By configuring the first toothed structure 31 to include a plurality of interconnected first teeth 311 and the second toothed structure 32 to include a plurality of interconnected second teeth 321, each first tooth 311 or second tooth 321 can form a sealing line at the connection. The combined action of multiple first teeth 311 or second teeth 321 can form multiple sealing lines, significantly improving the overall sealing performance. The smaller gaps between the multiple teeth allow for better filling of the connection area, reducing the possibility of leakage.
[0041] As a further improvement of this utility model, the transceiver body 10 includes a first sidewall 13 and a second sidewall 14 disposed opposite to each other. A through hole 15 is provided between the first cavity 111 and the second cavity 112, and the through hole 15 connects the first sidewall 13 and the second sidewall 14. By setting the transceiver body 10 to include the first sidewall 13 and the second sidewall 14 disposed opposite to each other, and providing a through hole 15 between the first cavity 111 and the second cavity 112, the through hole 15 connects the first sidewall 13 and the second sidewall 14, enabling air convection through the through hole 15. This helps to make the temperature distribution inside the cavity 11 more uniform and reduce the problem of local overheating. The design of the through hole 15 can reduce the amount of material used, thereby reducing the overall weight of the sealed transceiver. The through hole 15 can also serve as an assembly hole to realize the fixed installation of the sealed transceiver, expanding the application scenarios of the sealed transceiver.
[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0043] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
