Description

Technical Field

[0001] This utility model relates to the field of sensor technology, specifically to a protective structure for array sensors. Background Technology

[0002] Array sensors are widely used because they can achieve multi-point synchronous data acquisition and provide high-resolution detection results. In industrial automation production lines, array sensors can be used for product size detection and surface defect identification. In environmental monitoring scenarios, they can achieve accurate measurement of multiple parameters such as air quality, temperature and humidity. In intelligent transportation systems, they can assist in functions such as vehicle flow monitoring and pedestrian behavior analysis.

[0003] Chinese Utility Model Patent Publication No. CN219810475U discloses a protective structure and sensor. In use, the photoelectric sensor body passes through the protective coil, connecting sleeve, and fixing sleeve, and is fixed to both ends of the fixing sleeve with hexagonal thin nuts. The L-shaped support frame is fixed to the external mechanical equipment with bolts. The height of the photoelectric sensor body is adjusted by the length of the sliding plate extending relative to the L-shaped support frame. The angle of the photoelectric sensor body can be adjusted by adjusting the angle of the arc groove and the connecting seat. However, although the height of this protective structure and sensor can be adjusted, it is not designed with a sealing structure, which makes it easy for external dust, moisture and other contaminants to enter, thus affecting normal use. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide a protective structure for array sensors, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a protective structure for an array sensor, including a base box, an array sensor circuit board and a top cover. A sealing component is fixedly installed on the outer edge of the base box. A connecting frame two adapted to the sealing component is fixedly installed on the top cover near the base box. A sealing gasket one and a sealing gasket two are provided between the sealing component and the connecting frame two. A slot one and a slot two are provided on the connecting frame two near the base box.

[0006] The sealing assembly includes a connecting frame 1, and a positioning groove 1 and a positioning groove 2 are provided at one end of the connecting frame 1 near the top cover. The positioning groove 1 and the positioning groove 2, the sealing gasket 1 and the sealing gasket 2 are adapted to the slot 1 and the slot 2.

[0007] Preferably, a protrusion is fixedly installed at one end of the connecting frame one near the top cover, and a groove adapted to the protrusion is opened at one end of the connecting frame two near the bottom box.

[0008] The above technical solution, through the cooperation of the protrusion and the groove, can play a precise positioning role, which can ensure that the sealing gasket one and the sealing gasket two are accurately embedded in the slot and the positioning groove, avoiding poor sealing due to installation deviation, and enhancing the stability of the connection between the top cover and the bottom box, preventing relative displacement of the two when subjected to external force collision or vibration, and effectively blocking external dust, water vapor and other pollutants from entering.

[0009] Preferably, a first ear hook is fixedly installed at the outer edge of the bottom box, and a second ear hook is fixedly installed at the outer edge of the top cover. The first ear hook and the second ear hook are compatible with each other, and a positioning bolt is provided through the first ear hook and the second ear hook.

[0010] The above technical solution, through the combination of ear hook one, ear hook two and positioning bolt, can prevent the top cover from separating from the bottom box, ensure the normal operation of the sealing components, and avoid exposing the sensor array to harsh environments.

[0011] Preferably, there are three identical ear hooks, positioning pins and ear hooks, and the three ear hooks are distributed at equal intervals along the outer edges of the bottom box and the top cover.

[0012] Through the above technical solution, the three sets of ear hooks and positioning bolts distributed at equal intervals ensure that the connection force between the top cover and the bottom box is evenly distributed, avoiding local sealing failure or structural damage due to excessive force at a single point.

[0013] Preferably, a connecting seat is provided at the end of the top cover away from the bottom box, and a through groove is provided on the inner edge of the connecting seat away from the bottom box, extending to its inner surface. A sealing plug is installed in the connecting seat through the through groove, and the sealing plug and the through groove are interference fit.

[0014] Through the above technical solution, the interference fit design of the sealing plug and the through groove can effectively prevent external dust and moisture from entering the interior of the protective structure through the through groove when the through groove is not in use, thus protecting the sensor array from contamination. When external cables or equipment are required, the through groove can be flexibly opened to meet the functional requirements of data transmission and power supply of the sensor array.

[0015] Preferably, a connecting end is fixedly installed at one end of the bottom box, and a sleeve is inserted into the end of the connecting end away from the bottom box. A fixing groove adapted to the connecting end is opened on the inner surface of the sleeve, and a pull block is fixedly installed at the end of the sleeve away from the bottom box.

[0016] With the above technical solution, the fixing groove of the insert is aligned with the connecting end, and the insert is forcefully inserted along the connecting end until the connecting end is fully embedded in the fixing groove. When disassembling, the pull block is pulled to remove the insert from the connecting end, which can protect it when not in use.

[0017] Preferably, a connecting sleeve is fixedly installed at one end of the top cover near the bottom box, and the connecting sleeve is in contact with the array sensor circuit board.

[0018] Through the above technical solution, the contact between the connecting sleeve and the array sensor circuit board can play a positioning role, ensuring that the array sensor circuit board is accurately positioned in the bottom box and avoiding the impact of sensor detection accuracy due to installation misalignment.

[0019] Compared with the prior art, the present invention provides a protective structure for array sensors, which has the following beneficial effects:

[0020] 1. The protective structure used for array sensors can play a precise positioning role through the cooperation of protrusions and grooves. It can ensure that sealing gasket one and sealing gasket two are accurately embedded in the slot and positioning groove, avoiding poor sealing due to installation deviation. It also enhances the stability of the connection between the top cover and the bottom box, preventing relative displacement between the two when subjected to external impact or vibration, and effectively blocking external dust, water vapor and other pollutants from entering.

[0021] 2. The protective structure for array sensors features an interference fit design between the sealing plug and the through slot. When the through slot is not in use, it can effectively prevent external dust and moisture from entering the interior of the protective structure through the through slot, protecting the sensor array from contamination. When external cables or equipment are required, the through slot can be flexibly opened to meet the sensor array's data transmission, power supply, and other functional requirements.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1: As Figure 1-7 As shown, the protective structure for array sensors provided by this utility model includes a base box 1, an array sensor circuit board 7, and a top cover 12. A sealing component 2 is fixedly installed on the outer edge of the base box 1. A connecting frame 2 17 adapted to the sealing component 2 is fixedly installed on one end of the top cover 12 near the base box 1. A sealing gasket 5 and a sealing gasket 6 are provided between the sealing component 2 and the connecting frame 2 17. A slot 18 and a slot 2 19 are provided on one end of the connecting frame 2 17 near the base box 1.

[0032] The sealing assembly 2 includes a connecting frame 201. The connecting frame 201 has a positioning groove 202 and a positioning groove 203 at one end near the top cover 12. The positioning groove 202 and the positioning groove 203, the sealing gasket 5 and the sealing gasket 6 are adapted to the slot 18 and the slot 29.

[0033] Specifically, a protrusion 204 is fixedly installed at one end of the connecting frame 1 201 near the top cover 12, and a groove 20 that matches the protrusion 204 is opened at one end of the connecting frame 2 17 near the bottom box 1. The advantage is that the cooperation between the protrusion 204 and the groove 20 can play a precise positioning role, which can ensure that the sealing gasket 1 5 and the sealing gasket 2 6 are accurately embedded in the slot and positioning groove, avoiding poor sealing due to installation deviation, and enhancing the stability of the connection between the top cover 12 and the bottom box 1, preventing relative displacement of the two when subjected to external force collision or vibration, and effectively blocking external dust, water vapor and other pollutants from entering.

[0034] Specifically, a first ear hook 3 is fixedly installed on the outer edge of the bottom box 1, and a second ear hook 16 is fixedly installed on the outer edge of the top cover 12. The first ear hook 3 and the second ear hook 16 are compatible with each other, and a positioning bolt 4 is provided through the first ear hook 3 and the second ear hook 16. The advantage is that the combination of the first ear hook 3, the second ear hook 16 and the positioning bolt 4 can prevent the top cover 12 from separating from the bottom box 1, ensure the normal operation of the sealing component 2, and avoid the sensor array being exposed to harsh environments.

[0035] Specifically, there are three identical ear hooks 1-3, positioning pins 4, and ear hooks 2-16. The three ear hooks 1-3, positioning pins 4, and ear hooks 2-16 are evenly distributed at intervals along the outer edges of the bottom box 1 and the top cover 12. The advantage is that the three sets of ear hooks 1-3 and positioning pins 4 evenly distributed at intervals make the connection force between the top cover 12 and the bottom box 1 evenly distributed, avoiding local sealing failure or structural damage due to excessive force at a single point.

[0036] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0037] Specifically, a connecting seat 13 is provided at the end of the top cover 12 away from the bottom box 1. A through groove 14 is provided on the inner edge of the connecting seat 13 away from the bottom box 1, extending to its inner surface. A sealing plug 15 is inserted into the connecting seat 13 through the through groove 14. The sealing plug 15 and the through groove 14 are in an interference fit. The advantage is that the interference fit design between the sealing plug 15 and the through groove 14 can effectively prevent external dust and moisture from entering the interior of the protective structure through the through groove 14 when the through groove 14 is not in use, thus protecting the sensor array from contamination. When external cables or equipment are required, the through groove 14 can be flexibly opened to meet the functional requirements of data transmission and power supply of the sensor array.

[0038] Specifically, a connecting end 8 is fixedly installed at one end of the bottom box 1, and a sleeve 9 is inserted into the end of the connecting end 8 away from the bottom box 1. A fixing groove 10 adapted to the connecting end 8 is opened on the inner surface of the sleeve 9. A pull block 11 is fixedly installed at the end of the sleeve 9 away from the bottom box 1. The advantage is that the fixing groove 10 of the sleeve 9 is aligned with the connecting end 8, and the sleeve 9 is inserted into the connecting end 8 with force until the connecting end 8 is completely embedded in the fixing groove 10. When disassembling, the pull block 11 is pulled to pull the sleeve 9 out of the connecting end 8. When not in use, it can play a protective role.

[0039] Specifically, a connecting sleeve 21 is fixedly installed at one end of the top cover 12 near the bottom box 1. The connecting sleeve 21 is in contact with the array sensor circuit board 7. The advantage is that the contact between the connecting sleeve 21 and the array sensor circuit board 7 can play a positioning role, ensuring that the array sensor circuit board 7 is accurately positioned in the bottom box 1, and avoiding the impact of installation offset on the sensor detection accuracy.

[0040] Working Principle: During use, the cooperation between the protrusion 204 and the groove 20 provides precise positioning, ensuring that the sealing gasket 1 5 and sealing gasket 2 6 are accurately embedded in the slot and positioning groove, preventing poor sealing due to installation deviation. It also enhances the stability of the connection between the top cover 12 and the bottom box 1, preventing relative displacement when subjected to external impact or vibration, and effectively blocking external dust, moisture, and other contaminants from entering. The combination of ear hook 1 3, ear hook 2 16, and positioning bolt 4 prevents the top cover 12 from separating from the bottom box 1, ensuring the normal operation of the sealing assembly 2 and preventing the sensor array from being exposed to harsh environments. The three sets of equally spaced ear hooks 1 3 and positioning bolts 4 evenly distribute the connection force between the top cover 12 and the bottom box 1, preventing local sealing failure or structural damage due to excessive force at a single point. The interference fit design between the plug 15 and the through slot 14 effectively prevents external dust and moisture from entering the protective structure when the through slot 14 is not in use, protecting the sensor array from contamination. When external cables or equipment are needed, the through slot 14 can be flexibly opened to meet the data transmission and power supply requirements of the sensor array. The fixing slot 10 of the plug sleeve 9 is aligned with the connecting end 8, and the plug sleeve 9 is forcefully inserted along the connecting end 8 until the connecting end 8 is fully embedded in the fixing slot 10. When disassembling, pull the pull block 11 to pull the plug sleeve 9 out of the connecting end 8. When not in use, it can protect the plug sleeve. The contact between the connecting sleeve 21 and the array sensor circuit board 7 can serve a positioning function to ensure that the array sensor circuit board 7 is accurately positioned in the bottom box 1, avoiding the impact of installation misalignment on the sensor detection accuracy.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
