Description

Technical Field

[0001] The present invention relates to the technical field of sensors, and in particular to a quick-install sensor and a positioning method thereof. Background Art

[0002] A sensor is a device used to detect and measure physical quantities such as temperature, pressure, light, motion, etc., and convert these physical quantities into electrical signals or other measurable signals for analysis, monitoring or control of the system. It is widely used in various fields such as industrial automation, smart home, automobile, environmental monitoring, etc.

[0003] The design of the quick-release structure can facilitate the disassembly of the sensor, making the sensor easy to locate, disassemble and repair.

[0004] As in the prior art, Chinese patent publication number CN117589240A discloses a waterproof quick-detachable temperature and humidity sensor, including a fixing base, a female plug fixedly connected to one side of the lower end of the fixing base, a male plug inserted into the interior of the female plug, and a first shell fixedly connected to the end of the male plug away from the female plug. The interior of the first shell is detachably connected to the temperature and humidity sensor body, and one side of the first shell is movably connected to the second shell. The insertion rod is inserted into the mounting block. After the second magnetic block on the insertion rod contacts the first magnetic block in the mounting block, the two like-sex magnetic blocks generate mutual repulsion, pushing the first magnetic block to drive the resistance rod to move. After the resistance rod contacts the touch switch, the warning light lights up, and the connection between the first shell and the second shell is stable. Therefore, when the warning light goes out, the connection between the first shell and the second shell is unstable, which is convenient for staff to judge and makes the temperature and humidity sensor safer and more reliable to use.

[0005] For example, in the prior art, Chinese patent publication number CN113324572A discloses a modular assembled automotive sensor, which belongs to the field of automotive sensor technology and includes a base, a quick-loading mechanism is provided on the upper side of the base, and the left and right sides of the quick-loading mechanism are fixedly connected to the sensor body, and a positioning mechanism is provided on the front of the quick-loading mechanism. An installation mechanism is provided in the base, a wiring mechanism is provided in the base, and a drying mechanism is provided on the upper side of the wiring mechanism, and the drying mechanism is provided in the base. By providing the quick-loading mechanism, during installation, the quick-loading mechanism is pressed downward, and the arc surface of the arc plate can be received into the through hole under the action of the edge of the groove. When the arc block moves into the positioning groove, the quick-loading mechanism can be quickly installed. Under the action of the first guide wheel, the other end of the fixing rope can move and pull the arc block to move. At this time, the arc block can be separated from the positioning groove, so that the fixing cylinder is no longer fixed and the sensor body can be quickly disassembled.

[0006] Combined with the above materials, it can be seen that the sensor quick-install structure in the prior art generally adopts a snap-fit ​​structure instead of the traditional bolt fixation, so that there is no need to repeatedly twist the bolts during disassembly, thereby achieving the purpose of convenient disassembly and installation. However, in actual use, even if a snap-fit ​​mechanism is used, it is necessary to unplug and connect the cables during disassembly and assembly, which increases the disassembly and assembly steps. Summary of the Invention

[0007] The object of the present invention is to provide a quick-install sensor and a positioning method thereof, so as to solve the problem in the above-mentioned background art that the connection of cables during assembly and disassembly is complicated.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a quick-install sensor and a positioning method thereof, comprising a sensor body, the sensor body being mounted in the middle position above a mounting plate, and further comprising:

[0009] A junction block is fixedly mounted on the left side of the upper surface of the mounting plate, and the junction block is electrically connected to the printed circuit inside the mounting plate. A control button is mounted on the outside of the junction block, and a power line and a signal line are also connected to the side of the junction block.

[0010] Two copper contact posts are fixedly mounted in the middle of the upper surface of the mounting plate, and the contact posts correspond to the contact pieces fixedly mounted on the lower surface of the sensor body. A lifting plate is provided on the outside of the contact posts, and a cleaning mechanism is provided on the inside of the lifting plate for cleaning dust on the surface to avoid poor contact.

[0011] A left-right symmetrical cooling fan is installed on the upper surface of the mounting plate, and the cooling fan is rotatably connected to the mounting plate, and a fixing clip for fixing the sensor body is fixedly installed above the cooling fan;

[0012] Uniformly arranged heat dissipation fins are fixedly installed on the front and rear sides of the sensor body, and the lower surface of the sensor body and the adsorption magnetic strips fixedly installed on the upper surface of the mounting plate are magnetically attracted to each other.

[0013] Preferably, an L-shaped reset spring is fixedly installed between the outer surface of the cooling fan and the upper surface of the mounting plate, and the fixing clip on the upper surface of the cooling fan is engaged with the sensor body.

[0014] Preferably, a push plate is fixedly installed on the inner surface of the lower end of the cooling fan, and the two push plates correspond to the two ends of the lifting plate, and a return spring is fixedly installed between the lower surface of the lifting plate and the upper surface of the mounting plate.

[0015] Preferably, the cleaning mechanism includes an avoidance hole provided inside the lifting plate and a cleaning brush fixedly installed inside the avoidance hole, and the avoidance hole corresponds to the position of the contact post, and the cleaning brush contacts the outer surface of the contact post.

[0016] Preferably, a conveying groove is provided inside the lifting plate, and the position of the conveying groove corresponds to that of the cleaning brush, and the conveying groove is communicated with the lower end of the conveying pipe.

[0017] Preferably, the upper end of the delivery pipe and the extrusion airbag are communicated with each other, and the extrusion airbag is fixedly mounted on the inner surface of the heat dissipation fan, and the extrusion airbag and the sensor body are extruded with each other.

[0018] Preferably, a dust-sticking plate made of double-sided adhesive is pasted on the middle position of the upper surface of the mounting plate, and the position of the dust-sticking plate corresponds to the position of the cleaning brush in the upper and lower directions.

[0019] Preferably, the sensor body has side heat dissipation holes on its side, and the sensor body has top heat dissipation holes on its upper end, and the side heat dissipation holes and the top heat dissipation holes are interconnected, and the side heat dissipation holes correspond to the positions of the cooling fans.

[0020] Preferably, positioning holes are provided at the four corners of the lower surface of the sensor body, and the positioning holes and the positioning posts fixedly mounted on the upper surface of the mounting plate are inserted into each other for positioning.

[0021] Preferably, a positioning method for a quick-install sensor is characterized by comprising the following steps:

[0022] S1. Use bolts to secure the mounting plate to the device. Then, bend the cooling fans outward and place the sensor body between the left and right cooling fans. Insert the positioning posts on the upper surface of the mounting plate into the positioning holes on the lower surface of the sensor body.

[0023] S2. After placing the sensor body, slowly release the cooling fan. The elastic action of the reset spring pushes the cooling fan to rotate and reset. At this time, the sensor body moves downward under the action of its own gravity, and finally the cooling fan rotates to the vertical position;

[0024] S3. When the cooling fan rotates to a vertical position, the fixing clip above it clamps and fixes the sensor body. After the fixing is completed, the contact column fixed on the upper surface of the mounting plate contacts and is connected to the contact sheet on the lower surface of the sensor body.

[0025] S4. After the fixation is completed, connect the power line and signal line to the wiring block. After the cables are connected, turn on the control button to turn on the sensor body.

[0026] Compared with the prior art, the present invention has the following beneficial effects: the quick-install sensor and positioning method thereof adopt a novel structural design, the specific contents of which are as follows:

[0027] 1. This device uses a snap-fit ​​structure instead of transmission bolts or glue to fix. That is, the cooling fan is pushed by the elastic action of the reset spring, and finally the fixing clip above the cooling fan clamps the sensor body. When fixing, the positioning column and the positioning hole are used to achieve the purpose of positioning to prevent the sensor from shifting.

[0028] Furthermore, after the sensor body is fixed, the contact posts above the mounting plate and the contact pieces on the lower surface of the sensor body are in contact and conductive, thereby enabling the sensor body to operate normally. This structure eliminates the need to remove the connecting wires before disassembling the sensor body (both the power line and the signal line are connected to the wiring block, and the wiring block is connected to the contact posts using the printed circuit inside the mounting plate), making disassembly and maintenance more convenient.

[0029] 2. When the cooling fan is moved to disassemble the sensor body, the cooling fan drives the push plate inside to rotate. The push of the push plate and the elastic action of the reset spring make the lifting plate move up and down. During the movement of the lifting plate, use the cleaning brush inside the avoidance hole to clean the surface of the contact post to avoid dust adhering to the surface of the contact post after the sensor body is disassembled, which may cause poor contact later.

[0030] Furthermore, when the sensor body is fixed, the extrusion airbag on the inside of the cooling fan and the sensor body are squeezed against each other. At this time, the air in the extrusion airbag enters the conveying groove through the conveying pipe, and finally the air is ejected from the conveying groove, and the dust on the cleaning brush is blown off by the action of the airflow, so as to avoid affecting the cleaning effect of the subsequent cleaning brush.

[0031] 3. When the sensor body is in use, turn on the cooling fan. The airflow generated by the cooling fan enters the side heat dissipation holes and then is discharged from the side heat dissipation holes, thereby utilizing the flow of gas to cooperate with the heat dissipation fins outside the sensor body to achieve the purpose of heat dissipation.

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] Example 1: Please refer to Figure 1-Figure 3In order to achieve the purpose of facilitating the disassembly and assembly of the sensor, this embodiment provides the following technical solutions, which specifically disclose: a sensor body 1, the sensor body 1 is installed in the middle position above the mounting plate 2, a wiring block 3 is fixedly installed on the left side of the upper surface of the mounting plate 2, and the wiring block 3 is electrically connected to the printed circuit inside the mounting plate 2, and a control button 4 is installed on the outside of the wiring block 3, and a power line 5 and a signal line 6 are also connected to the side of the wiring block 3, two copper contact posts 7 are fixedly installed in the middle position of the upper surface of the mounting plate 2, and the contact posts 7 correspond to the contact pieces 8 fixedly installed on the lower surface of the sensor body 1, and the sensor Positioning holes 10 are provided at the four corners of the lower surface of the sensor body 1, and the positioning holes 10 and the positioning columns 9 fixedly mounted on the upper surface of the mounting plate 2 are inserted into each other for positioning. A bilaterally symmetrical cooling fan 11 is mounted on the upper surface of the mounting plate 2, and the cooling fan 11 is rotatably connected to the mounting plate 2. A fixing clip 12 for fixing the sensor body 1 is fixedly mounted above the cooling fan 11. A reset spring 13 with an "L"-shaped structure is fixedly mounted between the outer surface of the cooling fan 11 and the upper surface of the mounting plate 2, and the fixing clip 12 on the upper surface of the cooling fan 11 is engaged with the sensor body 1.

[0045] Use bolts to fix the mounting plate 2 on the equipment, then bend the cooling fan 11 outward, and then place the sensor body 1 between the cooling fans 11 on the left and right sides. At this time, the positioning columns 9 on the upper surface of the mounting plate 2 are inserted into the positioning holes 10 on the lower surface of the sensor body 1. After placing the sensor body 1, slowly release the cooling fan 11, and push the cooling fan 11 to rotate and reset under the elastic action of the reset spring 13. At this time, the sensor body 1 moves downward under the action of its own gravity, and finally the cooling fan 11 rotates to a vertical position. When the cooling fan 11 rotates to a vertical position, the fixing clip 12 above it clamps and fixes the sensor body 1. After the fixing is completed, the contact column 7 fixed on the upper surface of the mounting plate 2 is in contact with the contact piece 8 on the lower surface of the sensor body 1. After the fixing is completed, the power cord 5 and the signal line 6 are connected to the wiring block 3. After the cables are connected, turn on the control button 4 to turn on the sensor body 1.

[0046] Example 2: Please refer to Figures 4-10In order to achieve the purpose of cleaning the contacts, this embodiment provides the following technical solutions, which specifically disclose: a lifting plate 17 is provided on the outside of the contact column 7, and a cleaning mechanism for cleaning dust on its surface to avoid poor contact is provided on the inside of the lifting plate 17. A pushing plate 19 is fixedly installed on the inner surface of the lower end of the cooling fan 11, and the two pushing plates 19 correspond to the two ends of the lifting plate 17, and a return spring 18 is fixedly installed between the lower surface of the lifting plate 17 and the upper surface of the mounting plate 2. The cleaning mechanism includes an avoidance hole 20 opened inside the lifting plate 17 and a cleaning brush 21 fixedly installed inside the avoidance hole 20, and the avoidance hole 20 The position of the contact column 7 corresponds to each other, and the cleaning brush 21 contacts the outer surface of the contact column 7. A conveying groove 22 is opened inside the lifting plate 17, and the conveying groove 22 corresponds to the position of the cleaning brush 21, and the conveying groove 22 is connected to the lower end of the conveying pipe 24, and the upper end of the conveying pipe 24 is connected to the extrusion airbag 23, and the extrusion airbag 23 is fixedly installed on the inner surface of the cooling fan 11, and the extrusion airbag 23 and the sensor body 1 are squeezed against each other. A dust-sticking plate 25 made of double-sided tape is pasted in the middle of the upper surface of the mounting plate 2, and the position of the dust-sticking plate 25 corresponds to the position of the cleaning brush 21.

[0047] When disassembling and assembling the sensor body 1, the staff bends the cooling fan 11. At this time, the cooling fan 11 drives the pushing plate 19 inside it to rotate synchronously, and uses the pushing plate 19 to push the lifting plate 17 upward, and then drives the lifting plate 17 downward under the elastic pulling action of the return spring 18. In the process of the lifting plate 17 moving up and down, the avoidance hole 20 inside it moves relative to the contact column 7. At this time, the cleaning brush 21 inside the avoidance hole 20 cleans the surface of the contact column 7, and less dust adheres to cause poor contact of the contact column 7. When the cooling fan 11 is close to the sensor body 1 (that is, when the sensor body 1 is fixed), the extrusion airbag 23 inside the cooling fan 11 is squeezed with the sensor body 1. At this time, the air inside the extrusion airbag 23 enters the conveying groove 22 through the conveying pipe 24, and finally the airflow is ejected from the conveying groove 22, blowing off the dust on the cleaning brush 21, and the blown-off dust is stuck to the dust-sticking plate 25.

[0048] Example 3: Please refer to Figure 1-Figure 2 In order to achieve the purpose of dissipating heat for the sensor, this embodiment provides the following technical solutions, which specifically disclose: evenly arranged heat dissipation fins 14 are fixedly installed on the front and rear sides of the sensor body 1, and the adsorption magnetic strips 26 fixedly installed on the lower surface of the sensor body 1 and the upper surface of the mounting plate 2 are magnetically attracted to each other, side heat dissipation holes 15 are opened on the side of the sensor body 1, and top heat dissipation holes 16 are opened on the upper end of the sensor body 1, and the side heat dissipation holes 15 and the top heat dissipation holes 16 are connected to each other, and the side heat dissipation holes 15 correspond to the position of the cooling fan 11.

[0049] When the sensor body 1 is in use, the cooling fan 11 is turned on. The cooling fan 11 drives the surrounding air to flow. The flowing air enters the side heat dissipation holes 15 and is then discharged from the top heat dissipation holes 16. In this way, the flowing airflow is combined with the heat dissipation fins 14 on the side of the sensor body 1 to achieve the purpose of effective heat dissipation.
