Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

In this application, for convenience of explanation, the directions shown in fig. 1 are defined as the transverse directions, the directions along the X direction and the longitudinal directions along the Y direction, and the definitions herein are only for convenience of explanation of the technical solution and are not limited in any way.

As shown in fig. 1 and 2, the environmental noise detection device according to the embodiment of the present application includes a case 1, a detector 2, a display screen 3, and a rotating assembly 4, where the case 1 is used to fix the whole device on an external fixture to be detected, such as one side of a wall, or one side of an external support such as a cabinet, and may also be fixed by a support rod fixed on a base plate as shown in fig. 3; the other side of the housing 1 is adapted to house a detector 2 and a display 3. Wherein the detector 2 is slidably arranged at the top of the box 1, and the detector 2 is driven to move along the box 1 so as to be accommodated in the box; the display screen 3 is rotatably arranged at one side of the box body 1, specifically, at least one side wall of the box body is provided with a through hole 11, and the display screen 3 is rotatably arranged at the position of the through hole 11.

Still further, the display screen is rotatably disposed at the through-hole 11 through the rotation component 4, the rotation component 4 is disposed inside the case 1, and includes a rotation sleeve 41 fixedly disposed at one side of the display screen 3, and the rotation sleeve 41 is rotatably disposed in the case 1, so that the display screen 3 is driven to rotate relative to the case 1 when the rotation sleeve 41 rotates, and then the display screen is rotated into the case 1, so as to store the display screen 3 in a use state.

It will be appreciated that the display 3 is electrically connected to one end of the detector 2, so that the display 3 can display the noise information detected by the detector 2 in real time, so that the public can know the noise information.

It should be noted that, one or two through openings 11 may be provided, and the number of through openings 11 is to match the number of display screens 3; when the through-hole 11 is provided with one, it is provided on one of the two side walls of the case 1 in the lateral direction (lateral direction as shown in fig. 1); when two through-holes 11 are provided, the two through-holes 11 are provided on both lateral side walls of the case 1, respectively. And when being provided with two through-ports 11, be provided with two display screens 3 correspondingly, then rotate the cover 41 and be provided with two, two rotate the cover 41 and can both rotate for box 1, two rotate the cover 41 and control the rotation that corresponds display screen 3 respectively to realize the accomodating that corresponds display screen 3.

Further, as shown in fig. 4 and 5, the above-mentioned environmental noise detection device further includes a cover plate 5 and a filter plate 6, and the cover plate 5 and the filter plate 6 are fixedly connected with the display screen 3.

The cover plate 5 is fixedly arranged on one side, far away from the rotating sleeve 41, of the display screen 3, and when the display screen 3 rotates to the outer side of the box body 1 for normal use, the cover plate 5 is positioned at the top of the display screen 3, so that part of sunlight and rainwater can be shielded; and when the display screen 3 rotates into the box body 1 in bad weather, the cover plate 5 is abutted against the outer side of the box body 1 at the through opening 11 so as to shield the through opening 11 and prevent rainwater or other sundries from entering the box body.

The filter plate 6 is fixedly arranged at one side of the rotating sleeve 41, and when the display screen 3 rotates out of the box body 1 for normal use, the filter plate 6 is abutted against the inner side of the box body 1 at the through hole 11 so as to prevent external dust or sundries from entering the box body through the through hole 11.

More specifically, as shown in fig. 5, 8 and 12, the rotating assembly 4 further includes a support plate 42, a support rod 43 and a rotating body 411, where the support plate 42 is slidably disposed in the case 1, specifically, the support plate 42 can be driven to move in the case longitudinally; the support rod 43 is arranged on one side of the support plate 42, and when the support plate 42 moves longitudinally in the box body, the support rod 43 can be driven to move longitudinally in the box body 1, and one side of the support rod 43 away from the support plate 42 is arranged through the rotating sleeve 41 in a sliding manner.

The outer wall of the strut 43 is provided with a rotation groove 431, as shown in fig. 5, the inside of the rotation sleeve 41 is fixedly provided with a rotation body 411, and the rotation body 411 is slidably provided in the rotation groove 431. This causes the rod 43 to move through the rotating sleeve 41 when the rod 42 moves longitudinally in the case 1, and the rotating sleeve 41 rotates relative to the rod 42 under the action of the rotating body 411 and the rotating groove 431, thereby driving the display 3 to rotate.

It should be understood that, in the present application, the rotation of the rotating sleeve 41 is mainly used to rotate the display screen 3 into the case 1, so in the embodiment of the present application, as shown in fig. 8, the rotating groove 431 is a spiral groove, and the spiral angle of the spiral groove needs to be selected so that the display screen 3 can be rotated to the outside of the case 1 for display in the use state, and the display screen 3 can be rotated into the case 1 for storage in the storage state.

In addition, in the above technical solution, the rotating body 411 is disposed to drive the rotating sleeve 41 to rotate under the action of the rotating groove 431, so the shape of the rotating body 411 is required to be capable of meeting the requirement of rotating along with the movement of the rotating strut 43.

In a preferred embodiment, as shown again in fig. 12, the rotating assembly 4 further comprises a moving block 44 and a stop ring 45; wherein the moving block 44 is sleeved outside the supporting rod 43, the rotating sleeve 41 can rotate relative to the moving block 44, and the moving block 44 is connected with the inner wall of the box body 1 through an elastic piece 46; and the limiting ring 45 is fixedly arranged on one side of the supporting rod 43 close to the supporting plate 42, and the supporting plate 42 is provided with a sliding hole 421 along the transverse direction, and the limiting ring 45 is slidably arranged in the sliding hole 421.

In this solution, when the moving block 44 is driven by an external force to move along the lateral direction of the case 1, the supporting rod 43 can be driven to move along the lateral direction of the case 1.

The problem considered in this technical solution is that, when the display screen 3 needs to be stored in the case 1, the rotating sleeve 41 rotates, at this time, the cover plate 5 rotates to be parallel to the side wall of the case 1, but a certain distance remains between the cover plate 5 and the side wall of the case 1, that is, a part of the display screen may still exist outside the case 1 (as shown in fig. 6 and 7), at this time, if the weather is worse, damage to the display screen 3 may still be caused, and since the through-hole 11 is still exposed, part of rainwater and the like can enter the case through the through-hole 11, so that even a part of the display screen 3 stored in the case 1 cannot be well protected.

Through the arrangement of the above technical scheme, when the display screen 3 needs to be stored in the box body 1, the rotating sleeve 41 is driven to rotate by the longitudinal movement of the supporting rod 42, so that the display screen 3 rotates to be parallel to the side wall of the through opening 11 of the box body 1, namely, the state shown in fig. 6 and 7; then, the moving block 44 is driven by external force, so that the moving block 44 and the supporting rod 43 move in the box 1 transversely towards the middle of the box 1, and the display screen 3 is completely contained in the box until the cover plate 5 is attached to the side wall of the through opening 11 of the box 1 to shield the through opening 11, and rainwater and the like are prevented from entering the box 1 through the through opening 11.

It can be understood that in the above scheme, when the display screen 3 needs to be moved out of the case 1 for normal use, the moving block 44 is driven to move transversely toward the side wall of the case 1, so that the cover 5 is gradually far away from the side wall where the case through-hole 11 is located; then the supporting rod 43 moves towards the side where the supporting plate 42 is located along the longitudinal direction, so as to drive the rotating sleeve 41 to rotate reversely, and then drive the display screen 3 to rotate from the through hole 11 to the outer side of the box body 1 until the filter plate 6 abuts against the inner wall of the box body.

Of course, in the above technical solution, the driving of the moving block 44 moving in the lateral direction in the box may be a linear module set in the box 1, but in the embodiment of the application, considering the saving of the driving mechanism and the simplification of the motion control, as shown in fig. 8, a linear groove 432 is further formed at one end of the outer side of the strut 43 near the limiting ring 45, and the linear groove 432 is communicated with the rotating groove 431; the pushing block 47 is fixedly arranged in the box 1, and when the supporting rod 43 moves towards one side far away from the supporting plate 42, and the rotating body 411 moves into the linear groove 432, the pushing block 47 pushes the supporting rod 43 to move along the direction of the sliding hole 421.

In the above technical solution, when the strut 43 moves along the longitudinal direction toward the side far away from the strut 42, the rotating sleeve can act as follows:

first, the rotating groove 431 of the supporting rod 43 is firstly contacted with the rotating body 411 of the rotating sleeve 41, so that the movement of the supporting rod 43 can drive the rotating sleeve 41 to rotate, and the display screen 3 rotates to a first state (the state shown in fig. 6 and 7);

in the second step, the supporting rod 43 continues to move, so that the linear groove 432 of the supporting rod 43 contacts with the rotating body 411, that is, the movement of the supporting rod 43 does not drive the rotating sleeve 411 to rotate any more, at this time, the pushing block 47 pushes the supporting rod 43 to move laterally, and the limiting ring 45 moves in the sliding hole 421, so that the cover plate 5 approaches to the sidewall where the through hole 11 of the box body is located, and at this time, the display screen 3 moves to the second state (as shown in fig. 9 and 10).

In this solution, the pushing block 47 is configured to push the strut 43/moving block 44 laterally, so that the strut 43 moves laterally, and then the display screen 3 moves from the first state position to the second state position, so that a side surface of the pushing block 47 near the strut 43 can change the movement form of the strut 43, and in the following description, the side surface capable of changing the movement form of the strut 43 is defined as an acting surface for convenience of explanation.

Under this concept, in the embodiment of the present application, the arrangement scheme of the pushing block 47 may be as follows:

1) The pushing block 47 is arranged on one side of the supporting rod 43 close to the side wall of the corresponding box body 4, and the longer the acting surface is from the supporting plate to the side wall of the corresponding box body 4, so that when the supporting rod 43 is abutted against the acting surface and moves towards the side far from the supporting plate 42, the display screen 3 can be driven to move towards the inside of the box body;

in this solution, the elastic member 46 is a spring disposed at one side of the moving block, and the other end of the spring is connected to the inner wall of the case 4, and the spring is gradually stretched as the strut 43 collides against the acting surface and moves toward the side away from the strut 42;

when the display screen 3 needs to be moved to the outside of the box body 1 for normal use, the supporting rod 43 moves in the box body 1 along the longitudinal direction towards the side where the supporting plate 42 is located, and under the action of the spring tension, the supporting rod 43 still abuts against the acting surface of the pushing block 47, so that the supporting rod 43 gradually moves towards the side where the corresponding through hole 11 is located, and the display screen 3 gradually rotates from the second state to the first state; the support rods 73 then continue to move towards the side of the support plates 42, and the rotating sleeve rotates under the action of the rotating grooves, so that the display screen rotates out of the box.

2) The pushing block is arranged on one side of the supporting rod, which is far away from the side wall of the corresponding box body, and the longer the acting surface is from the side wall of the corresponding box body along with the distance from the supporting plate;

in this scheme, as shown in fig. 12, an auxiliary block 433 is fixedly arranged on one side of the support rod far away from the support plate, so that when the auxiliary block 433 is abutted against the action surface and moves towards one side far away from the support plate, the display screen can be driven to move towards the inside of the box body; and the pushing block 47 includes a smooth section 471 and a moving section 472, and when the rotating body 411 slides in the rotating groove 431, the auxiliary block 433 abuts against the smooth section 471; when the rotator 411 slides in the linear slot 432, the auxiliary block 433 abuts against the moving section 472, so that the strut 43 moves along the sliding hole 421.

That is, in this embodiment, the moving section 472 of the pushing block 47 is the aforementioned acting surface, and when the auxiliary block abuts against the moving section 472, the supporting rod 43 moves not only longitudinally in the case, but also transversely to move the display screen into the case.

Based on the same principle, in this solution, the elastic member is a spring disposed at one side of the moving block, when the supporting rod starts to move, that is, when the movement of the supporting rod 43 drives the display screen 3 to rotate, the auxiliary block 433 abuts against the smooth section 471, at this time, the spring is compressed, and when the auxiliary block 433 moves to the moving section 172, the compressed spring pushes the auxiliary block 433 to move toward the inner side of the case in the lateral direction.

In both the above solutions, the movement of the strut in the lateral direction in the box is achieved on the basis of the action of the elastic element (spring), in order to ensure the stability of the movement, in some embodiments, the box is fixedly provided with a support frame 13 close to the position of the spring, and the moving block is slidingly arranged in the corresponding support frame 13.

The key point of the technical scheme is that the display screen is accommodated in the box body. It will be appreciated that the detector 2 for detecting ambient noise also needs to be housed in the housing when it is subjected to heavy rain or bad weather, and therefore in embodiments of the present application the ambient noise detection device further comprises a movement assembly 7 for driving the detector along the housing, facilitating the housing of the detector in the housing.

Wherein, as shown in fig. 13, the moving assembly comprises a screw 71 and a slide post 72; the screw rod 71 is rotatably arranged in the box body 1; the sliding column 72 is screwed on one end of the screw rod 71, and when the screw rod 71 rotates, the sliding column 72 moves in the box body, and the sliding column 72 is fixedly arranged at the bottom end of the detector 2 to drive the detector 2 to move. So that when the detector 2 needs to be stored, the screw 71 is driven to rotate by a driving mechanism arranged in the box 1, and then the slide column 72 moves up and down in the box.

In the embodiment of the present application, the driving mechanism for driving the screw 71 to rotate is a driving motor 73 fixedly disposed in the box, and the screw 71 is fixedly disposed at an output end of the driving motor 73.

In a more preferable solution, as shown in fig. 14, a storage barrel 12 is fixedly arranged in the box body near the top end, the sliding column 72 can slide through the storage barrel 12, and when the sliding column 72 drives the detector 2 to move into the box body under the driving of the screw rod 71, the detector 2 is stored in the storage barrel 12, so that the detector 2 is further protected.

In some embodiments of the present application, two of the detectors 2 are provided, and both of the detectors 2 can be moved into the case 1; and the two detectors 2 are connected with the same top cover 8, and when the detectors 2 move into the box 1, the top cover 8 is abutted against the top wall of the box.

In this scheme, when the detector is housed in the housing tube 12, the top cover 8 abuts against the top wall of the case, and external rainwater or the like is prevented from entering the case from the top of the case 1, so that the detector 2 and the display screen 3 are effectively protected.

As can be seen from the above-described technical solution, in the present application, the detector 2 is accommodated by the moving assembly 7, the display screen 3 is accommodated by the rotating assembly 4, the moving assembly 7 is driven by the driving motor 73 fixedly arranged in the box, and the driving of the rotating assembly may be a linear driving mechanism driving the supporting rod 43 to move longitudinally in the box during the actual working process.

In a preferred embodiment, as shown in fig. 13, a driving gear 48 is fixedly disposed at one end of the screw 71, a toothed plate 49 is fixedly disposed at one side of the support plate 42, and the toothed plate 49 is meshed with one side of the driving gear 48, so that the moving assembly 7 and the rotating assembly 4 synchronously operate.

The technical proposal ensures that the detector 2 and the display screen 3 are stored synchronously, and is beneficial to saving the driving mechanism and simplifying the control program.

The number of the display screen 3 may be two, and when the display screen 3 is provided with two display screens, the two support rods 43 for driving the display screen 3 to rotate are provided with two corresponding support rods, in this case, the two support rods 43 are connected with the same support plate 42, the two sides of the support plate 42 are provided with the sliding holes 421, and the support rods 43 are respectively arranged in the corresponding sliding holes 421.

In this case, when the screw 71 rotates, the driving gear 48 is driven to rotate, and the two struts 43 can be driven to move synchronously through the toothed plate 49 and the support plate 42, that is, the display screens 3 on both sides can be rotated synchronously and stored in the case 1.

The method for detecting the environmental noise by the environmental noise detection device comprises the following steps:

the case 1 is installed at one side of an external fixture to be detected, which may be a wall or a cabinet, etc., and when there is no wall or cabinet for supporting, a support bar fixed to a base plate as shown in fig. 3 may be provided as an external fixture for supporting the case formation.

Under normal use condition, detector 2 and display screen 3 remove box 1, and detector 2 is used for detecting ambient noise, and display screen 3 is used for showing the ambient noise information that the detector detected.

When a severe rainy day or other severe weather is met, the detector 2 is moved to be contained in the case 1; simultaneously, the display screen 3 is rotated into the box body 1 from the through hole 11 through the rotating component 4;

specifically, when rainy days or other bad weather are met, the driving motor 73 drives the screw rod 71 to rotate; on the one hand, the support plate 42 can be driven to move by the driving gear 48 and the toothed plate 49 through the rotation of the screw 71, and the support rod 43 is driven to longitudinally move in the box body 1 through the movement of the support plate 42; the movement of the support rod 43 firstly drives the rotating sleeve 41 to rotate, so that the display screen 6 rotates from the use state to the first state, then the support rod 43 continues to move to drive the display screen 3 to move transversely, so that the display screen 3 moves from the first state to the second state to finish the storage of the display screen 3, and the through hole 44 on the corresponding side of the display screen 3 is covered by the cover plate 5; rotation of the screw 71, on the other hand, moves the detector 2 by the spool 72 to receive the detector 2 into the receiving cylinder 12 and to cover the path through which the detector 2 moves by the top cover 8.

Through the steps, the detector 2 and the display screen 3 can be accommodated in the box body 1, and the moving channels of the detector 2 and the display screen 3 are closed through the cover plate 5 and the top cover 8, so that external rainwater or other sundries are prevented from entering the box body 1.
