[0024] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following examples. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0025] like Figure 1-7 As shown, a vehicle-mounted atmosphere detector includes a body 21, a magnetic device 22 for connecting to the vehicle roof is provided at the bottom of the body 21, the magnetic device 22 includes a permanent magnet 25, a first iron pad 26 and a second iron pad 27 arranged in sequence from top to bottom, the second iron pad 27 is fixed to the bottom surface of the body 21 through a copper column 271, the permanent magnet 25 is slidably connected to the copper column 271 in the vertical direction, the first iron pad 26 is slidably arranged in the horizontal direction and the first iron pad 26 is movably arranged in the vertical direction; The permanent magnet 25, the first iron pad 26 and the second iron pad 27 are assembled to move in the following two workstations: workstation one, the permanent magnet 25, the first iron pad 26 and the second iron pad 27 are tightly fitted together, and at this time the first iron pad 26 and the second iron pad 27 are magnetized by the permanent magnet 25; and workstation two, the first iron pad 26 is removed from between the permanent magnet 25 and the second iron pad 27 in the horizontal direction, and the permanent magnet 25 and the second iron pad 27 are spaced apart, and at this time the second iron pad 27 can shield the magnetic field below the permanent magnet 25. When the permanent magnet 25, the first iron pad 26, and the second iron pad 27 are overlapped with each other, the three can be regarded as a whole, which can be effectively adsorbed on the vehicle roof; and when the first iron pad 26 is pulled out, a gap appears between the permanent magnet 25 and the second iron pad 27, and the magnetic field is refracted between the air and the second iron pad 27, thereby shielding the magnetic field under the second iron pad 27, so that the suction force between the second iron pad 27 and the roof is weakened or even disappears. At this time, the operator can easily remove the detection module from the roof.

[0026] Furthermore, the magnetic attraction device 22 also includes a side insert block 255 made of a non-ferromagnetic material. The side insert block 255 is arranged to slide in the horizontal direction. The side insert block 255 is assembled so that when the first iron block 26 is removed from between the permanent magnet 25 and the second iron block 27, the side insert block 255 can be inserted between the permanent magnet 25 and the second iron block 27 and lift the permanent magnet 25 a certain distance. When the first iron block 26 is inserted between the permanent magnet 25 and the second iron block 27, the side insert block 255 can be removed from between the permanent magnet 25 and the second iron block 27. The side insert block 255 can prevent the permanent magnet 25 from fitting with the second iron block 27 after the first iron block 26 is removed, and the side insert block 255 lifts the permanent magnet 25 by a distance so that the height of the gap between the permanent magnet 25 and the second iron block 27 is greater than the thickness of the first iron block 26, thereby facilitating the reinsertion of the first iron block 26.

[0027] Specifically, a fixed bracket 254 is provided at the bottom of the body 21, and the side insert block 255 is slidably connected to the fixed bracket 254 through a horizontally arranged first guide rod 2551, and the sliding direction of the side insert block 255 is parallel to the sliding direction of the first iron pad 26. The first guide rod 2551 is provided with a baffle 2553 at the end away from the side insert block 255, and the baffle 2553 is blocked on the sliding path of the first iron pad 26, and when the first iron pad 26 moves out from between the permanent magnet 25 and the second iron pad 27, it can be blocked by the baffle 2553 and drive the side insert block 255 to be inserted between the permanent magnet 25 and the second iron pad 27; a first elastic unit 2552 is provided between the side insert block 255 and the fixed bracket 254, and the first elastic unit 2552 is assembled so that its elastic force can drive the side insert block 255 to move out from between the permanent magnet 25 and the second iron pad 27. The present invention implements a linkage design for the side insert block 255 and the first iron block 26. When the first iron block 26 is pulled out, the side insert block 255 can be automatically driven to be inserted, thereby reducing the use of driving elements, simplifying the equipment structure, and improving the reliability of the mechanism.

[0028] Furthermore, the magnetic attraction device 22 also includes a magnet locking mechanism, which is assembled so that when the permanent magnet 25 is lifted by the side insert block 255, the magnet locking mechanism can keep the permanent magnet 25 in the lifting position, and when the first iron pad 26 is fully inserted between the permanent magnet 25 and the second iron pad 27, the first iron pad 26 can unlock the magnet locking mechanism and allow the permanent magnet 25 to fall back downward. Specifically, the magnetic locking mechanism includes a sleeve 251 fixed to the upper end of the permanent magnet 25, and a clamping plate 252 slidably connected to the fixed bracket 254 in the horizontal direction, the sliding direction of the clamping plate 252 is parallel to the sliding direction of the first iron pad 26, the outer ring surface of the sleeve 251 is provided with an annular groove 2511, the clamping plate 252 is provided with a through hole 2524 for the sleeve 251 to pass through and a U-shaped notch 2525 connected to the through hole 2524, the width of the U-shaped notch 2525 is smaller than the diameter of the outer ring surface of the sleeve 251 and larger than the diameter of the bottom ring surface of the annular groove 2511, the opening direction of the U-shaped notch 2525 is parallel to the sliding direction of the clamping plate 252, and the clamping plate 252 is assembled to slide between the following two stations: station a, the through hole 2524 is vertically opposite to the sleeve 251, and station b, the U-shaped The notch portion 2525 is vertically opposite to the sliding sleeve 251 and the U-shaped notch portion 2525 is stuck in the annular groove 2511 of the sliding sleeve 251; the card plate 252 is slidably connected to the fixed bracket 254 through the second guide column 2521, and the second guide column 2521 is provided with a push plate 2523 on the side away from the card plate 252. The first iron pad 26 is connected with a protruding structure protruding upward, and the push plate 2523 is blocked on the translation path of the protruding structure. When the first iron pad 26 is inserted between the permanent magnet and the second iron pad 27, the protruding structure is blocked by the push plate 2523 and drives the card plate 252 to move from station b to station a; a second elastic unit 2522 is also provided between the card plate 252 and the fixed bracket 254, and the second elastic unit 2522 is assembled so that its elastic force can drive the card plate 252 to move from station a to station b. A third elastic unit 253 is provided between the permanent magnet 25 and the bottom surface of the body 21. The third elastic unit 253 is configured so that its elastic force can drive the permanent magnet 25 to move downward relative to the body 21. The locking mechanism can lock the permanent magnet 25 in a raised state. During the insertion of the first iron block 26, even if the side insert block 255 is pulled out, the permanent magnet 25 will not fall downward, thereby preventing the permanent magnet 25 from squeezing the first iron block 26 and thereby increasing the resistance of the first iron block 26 during insertion. When the first iron block 26 is about to be fully inserted into place, the locking mechanism can be unlocked again, so that the permanent magnet 25, the first iron block 26, and the second iron block 27 are tightly fitted together, ensuring the continuity of the internal magnetic fields of the three.

A fourth elastic unit 263 is provided between the lifting bracket 261 and the horizontal sliding bracket 262, and the fourth elastic unit 263 is configured so that its elastic force can drive the lifting bracket 261 to move upward relative to the horizontal sliding bracket 262. The wear caused by the long-term reciprocating motion of the first iron pad 26 may cause a gap to form between it and the permanent magnet 25 and the second iron pad 27. The present invention configures the first iron pad 26 as an elastic floating structure, which can effectively compensate for the above-mentioned wear and ensure that the first iron pad 26 can still fit tightly with the permanent magnet 25 and the second iron pad 27 after long-term use.
