[0086] Electronic devices are increasingly used in people's daily lives. As users' requirements for electronic devices continue to increase, the problem of various abnormal noises generated by electronic devices during use has gradually become prominent. Therefore, electronic devices usually use abnormal noise detection equipment to detect various abnormal noises generated by themselves during production and processing to improve the quality of electronic devices. The current abnormal noise detection equipment will generate a certain amount of noise when it is working. This noise will be mixed with the noise emitted by the electronic equipment, thereby interfering with the abnormal noise detection of the electronic equipment, resulting in the accuracy and objectivity of the detection results of the abnormal noise detection equipment being low, and it is difficult to detect the actual abnormal noise of the electronic equipment.

[0087] In response to the above problems, such as Figure 1As shown, an embodiment of the present application provides an abnormal sound detection device, including a shell 1, a detection member 2, a driving member 3 and a swing member 4.

[0088] Among them, the housing 1 can be a rectangular or square box made of sound insulation material, which is used to accommodate the part to be detected 9. In this embodiment, the part to be detected 9 is the electronic device mentioned above. Specifically, the part to be detected 9 can be a series of electronic devices such as mobile phones, tablet computers, laptops, smart watches, smart bracelets, etc., and of course it can also be a module in the electronic device, such as a camera module in a mobile phone, etc. The housing 1 can be provided with an openable and closable door (not shown in the figure), and the part to be detected 9 can be placed in the housing 1 by opening the door on the housing 1 for relevant detection. The housing 1 can isolate the external sound, thereby reducing the possibility of external sound interfering with the detection of the part to be detected 9, so as to improve the accuracy of the abnormal sound detection device.

[0089] For ease of understanding, the length direction of the shell 1 is defined as the X-axis direction, the width direction of the shell 1 is defined as the Y-axis direction, and the height direction of the shell 1 is defined as the Z-axis direction.

[0090] The detection member 2 is arranged in the housing 1 and is used to detect the abnormal sound of the component to be detected 9. Along the height direction Z of the housing 1, the detection member 2 can be installed on the top wall of the housing 1. Specifically, the detection member 2 can have a sensor 21, and the sensor 21 can be connected to the top wall of the housing 1 through a guide rail 22. The sensor 21 can be a sound sensor, which can collect the abnormal sound emitted by the component to be detected 9.

[0091] The driving member 3 can be a motor, or a pneumatic motor, a hydraulic motor or other types of driving components. Along the height direction Z of the housing 1, the driving member 3 is located at the bottom of the housing 1. The driving member 3 is used to drive the swing member 4 to move, so that the swing member 4 can drive the detection member 9 to move. The driving member 3 can achieve the shaking of the detection member 9 to simulate the scene when the detection member 9 shakes under normal use, so that the detection member 2 can detect the abnormal sound emitted by the detection member 9 under the shaking condition.

[0092] A soundproof box 11 is arranged in the shell 1. The soundproof box 11 can be a rectangular or square box made of soundproof material. The soundproof box 11 is arranged at the bottom of the shell 1. Specifically, the soundproof box 11 can be directly welded to the bottom wall of the shell 1, or the soundproof box 11 can be fixed to the bottom wall of the shell 1 by screws and other parts. Of course, other installation methods can also be used, and there is no specific limitation in the embodiment of the present application. The above-mentioned driving member 3 is located in the soundproof box 11. The function of the soundproof box 11 is to isolate and shield the abnormal noise emitted by the driving member 3 during operation, thereby reducing the possibility that the noise of the driving member 3 interferes with the detection of the detection member 9, which is conducive to improving the accuracy of abnormal sound detection.

[0093] One end of the swing member 4 is located inside the soundproof box 11 and connected to the driving member 3, and the other end is located outside the soundproof box 11 and is used to connect to the to-be-detected member 9, so that the driving member 3 can drive the swing member 4 to drive the to-be-detected member 9 to move. Specifically, the swing member 4 can be connected to a clamping member 8, which is used to carry and fix the to-be-detected member 9, thereby reducing the possibility of the to-be-detected member 9 being disconnected from the swing member 4 during the shaking process, so as to improve the reliability of the abnormal sound detection device.

[0094] The following is a further explanation of the example of the part to be detected 9 being a mobile phone. In the process of the user using the mobile phone, the mobile phone will shake to a certain extent as the user moves. At this time, some parts inside the mobile phone will collide with each other due to loose assembly or other reasons, thereby generating abnormal noise, affecting the normal use of the user and causing the user's experience to decline. For example, in the case of shaking, the motor in the camera module of the mobile phone is easy to collide with the base of the camera module or the camera body, thereby generating abnormal noise. In view of the above-mentioned abnormal noise problem, the embodiment of the present application provides an abnormal noise detection device. When the mobile phone is placed in the housing 1 of the abnormal noise detection device, the mobile phone can be connected to the swing member 4 through the clamping member 8 so that the mobile phone is fixed at the upper end of the swing member 4, and then the driving member 3 is started. The driving member 3 can drive the mobile phone to shake through the swing member 4. At this time, the mobile phone with problems will make abnormal noises, and the detection member 2 can detect the abnormal noises, which is convenient for the staff to understand the real situation of the abnormal noises of the mobile phone.

[0095] Among them, considering that the driver 3 itself will also make noise when working, the noise is easy to be mixed with the abnormal noise of the mobile phone, thereby interfering with the normal detection work, and then affecting the accuracy of the detection. In view of this problem, the embodiment of the present application sets a soundproof box with a soundproof effect in the shell 1, and puts the driver 3 into the soundproof box 11, so that the soundproof box 11 plays a role of shielding and isolating the noise emitted by the driver 3, thereby reducing the possibility of the noise of the driver 3 interfering with the abnormal sound detection, that is, reducing the possibility of the braking noise generated by the abnormal sound detection device itself affecting the detection of the mobile phone, so that the abnormal sound detection device can detect the abnormal sound of the mobile phone more realistically, objectively and accurately, thereby helping to improve the accuracy of the detection. On the other hand, the abnormal sound detection device is conducive to realizing automated detection work, reducing the possibility of using manual detection, and while accurately characterizing the actual abnormal sound situation of the mobile phone, it also improves the efficiency of detection.

[0096] As can be seen from the above, the abnormal noise detection device provided in the embodiment of the present application can isolate the operating noise of the driving member 3 from the abnormal noise of the detected member 9 itself to improve the accuracy of the detection. Therefore, the detected member 9 must be arranged outside the soundproof box 11, and the driving member 3 and the detected member 9 are connected through the swing member 4, then the swing member 4 will be connected to the soundproof box 11, that is, the swing member 4 will extend into the soundproof box 11 to achieve the connection with the driving member 3. In this case, the connection between the swing member 4 and the top wall of the soundproof box 11 is also prone to generate certain noise,

[0097] For example, the noise transmitted outward by the driving member 3 through the gap at the connection. Specifically, a certain installation space is provided on the top wall of the sound insulation box 11 so that the swinging member 4 can extend into the interior of the sound insulation box 11 and provide space for the swinging member 4 to move. The operating noise of the driving member 3 is easily transmitted outward through the above-mentioned installation space, causing the phenomenon of "sound leakage"; for another example, the noise may be the noise emitted by the swinging member 4 when it moves itself; for another example, the noise may also be the noise emitted by the swinging member 4 colliding with the top wall of the sound insulation box 11 when it moves, and so on. It is difficult to isolate the above-mentioned series of noises by the sound insulation box 11 itself, and these noises are also likely to interfere with the detection work of the component 9 to be detected.

[0098] In view of this, in the abnormal sound detection device provided in the embodiment of the present application, a sound insulation installation platform 5 is provided on the top wall of the sound insulation box 11, and the swing member 4 is connected to the sound insulation box 11 through the sound insulation installation platform 5. By providing the sound insulation installation platform 5, the noise that may be generated at the connection between the swing member 4 and the top wall of the sound insulation box 11 is shielded, thereby effectively improving the accuracy of the detection.

[0099] like Figure 2 Please also refer to Figure 1The sound insulation installation platform 5 may include a first sound insulation board 51 installed on the upper side of the top wall of the sound insulation box 11, please refer to Figure 3 The sound insulation installation platform 5 may also include a second sound insulation board 52 installed on the lower side of the top wall of the sound insulation box 11. The first sound insulation board 51 and the second sound insulation board 52 may be made of sound insulation materials, so that the entire sound insulation installation platform 5 can more effectively isolate and shield noise.

[0100] The above-mentioned swinging member 4 extends into the interior of the soundproof box 11 through the soundproof mounting platform 5, and is movably connected to the soundproof mounting platform 5. The swinging member 4 can pass through the top wall of the soundproof box 11 and extend into the interior of the soundproof box 11. Therefore, by providing the soundproof mounting platform 5 with good soundproofing effect, the soundproof mounting platform 5 has a soundproofing effect on the connection between the swinging member 4 and the soundproof box 11, which is conducive to further isolating the above-mentioned noise, and then is conducive to improving the objectivity and accuracy of the abnormal sound detection device, and further improving the reliability of the abnormal sound detection device.

[0101] Of course, the abnormal sound detection device can also be used to detect abnormal sounds emitted by the to-be-detected member 9 in a stationary state, that is, during the detection process, the driving member 3 can also be disabled, so that the swing member 4 is in a stationary state, and the to-be-detected member 9 can be detected at this time. The following is an example of detecting the abnormal sound of the background noise emitted by the camera module in a mobile phone: First, turn on the camera device in the mobile phone to put it in a working state, then open the housing 1 and put the mobile phone on the clamping member 8, and put the mobile phone in a stationary state. At this time, the detection member 2 can detect the abnormal sound of the background noise emitted by the mobile phone.

[0102] It can be seen from this that the abnormal sound detection device provided in the embodiment of the present application can realize the abnormal sound detection function of the component to be detected 9 in a static state and in a moving state.

[0103] like Figure 2 As shown, in a possible implementation, the above-mentioned swing member 4 may include a first swing rod 41 and a second swing rod 42 that are movably connected to each other. The first swing rod 41 and the second swing rod 42 may both be rod-shaped bodies, and the material thereof may be metal, plastic or other materials that meet the use requirements. Please continue to refer to Figure 1 Under the action of the driving member 3, the first swing rod 41 and the second swing rod 42 can swing accordingly to drive the detected member 9 to move, thereby simulating the scene when the detected member 9 shakes. The first swing rod 41 and the second swing rod 42 have a relatively simple structure and high reliability, which is conducive to achieving stable movement of the detected member 9, thereby facilitating improving the accuracy of detection.

[0104] The first swing arm 41 and the second swing arm 42 are respectively located on both sides of the sound insulation installation platform 5. Specifically, the first swing arm 41 can be located outside the sound insulation box 11, and the second swing arm 42 can be located inside the sound insulation box 11. The end of the first swing arm 41 away from the second swing arm 42 is used to connect with the to-be-detected part 9, and the end of the second swing arm 42 away from the first swing arm 41 is connected to the driving member 3. The first swing arm 41 and the second swing arm 42 are respectively movably connected to the sound insulation installation platform 5, that is, the first swing arm 41 and the second swing arm 42 can both move relative to the sound insulation installation platform 5, thereby realizing the movement of the to-be-detected part 9.

[0105] In the above embodiment, the first swing rod 41 is connected to the second swing rod 42, and the first swing rod 41 can move relative to the second swing rod 42. Under the drive of the driving member 3, the second swing rod 42 drives the detection member 9 to swing through the first swing rod 41, so that the abnormal sound detection device can detect the abnormal sound of the detection member 9 in the shaking state. Such a design is conducive to realizing the connection between the driving member 3 and the detection member 9, thereby facilitating the movement of the detection member 9, so as to facilitate the detection of the abnormal sound of the detection member 9 in the movement state.

[0106] like Figure 3 As shown, in a possible embodiment, the above-mentioned swinging member 4 also includes a connecting member 43, and the connecting member 43 can be a slider, and its shape can be square or round, etc., and its material can be plastic, or metal or other materials can be selected, and no further restrictions are made in the embodiments of the present application.

[0107] The first swing rod 41 is movably connected to the second swing rod 42 through a connecting member 43. Specifically, Figure 4 As shown, a matching groove 431 may be provided on the connecting member 43, the bottom of the first swing rod 41 has a first matching portion 412, and the top of the second swing rod 42 has a second matching portion 422. The first matching portion 412 and the second matching portion 422 can extend into the matching groove 431 and can match with the matching groove 431, thereby realizing a movable connection between the first swing rod 41, the second swing rod 42 and the connecting member 43. By providing the connecting member 43, it is beneficial to realize the connection between the first swing rod 41 and the second swing rod 42, thereby facilitating the movement of the first swing rod 41 and the second swing rod 42. At the same time, such a design is beneficial to improving the stability and reliability of the connection between the first swing rod 41 and the second swing rod 42, and is beneficial to realizing the smooth and fluent movement of the first swing rod 41 and the second swing rod 42, thereby improving the stability of the movement of the to-be-detected member 9, and further improving the accuracy of the detection by the abnormal sound detection device.

[0108] like Figure 5As shown, the soundproof mounting platform 5 may include a mounting groove 54 provided on the top wall of the soundproof box 11, and the connecting member 43 is arranged in the mounting groove 54 and can move relative to the mounting groove 54. Specifically, under the action of the driving member 3, the second swing arm 42 can drive the connecting member 43 to move in the mounting groove 54, thereby driving the first swing arm 41 to move. The mounting groove 54 can play the role of installing and limiting the connecting member 43. Since the soundproof mounting platform 5 has a good soundproofing effect, therefore, arranging the connecting member 43 in the mounting groove 54 of the soundproof mounting platform 5 is conducive to isolating the noise generated when the connecting member 43 moves, reducing the possibility of the noise interfering with the detection of the detection member 9, and further helping to improve the accuracy and objectivity of the abnormal sound detection device.

[0109] like Figure 3 As shown, in a possible implementation, the sound insulation installation platform 5 further includes a first sound insulation board 51 and a second sound insulation board 52 located on both sides of the installation slot 54. The first sound insulation board 51 and the second sound insulation board 52 are both made of sound insulation materials, and both are plate-shaped members. Figure 5 , the mounting groove 54 can be a through groove provided on the top wall of the soundproof box 11. Along the height direction Z of the shell 1, the first soundproof board 51 and the second soundproof board 52 are respectively located on both sides of the mounting groove 54. The first soundproof board 51 is installed on the upper surface of the top wall of the soundproof box 11, and the second soundproof board 52 is installed on the lower surface of the top wall of the soundproof box 11. That is, the first soundproof board 51 and the second soundproof board 52 can be regarded as the top wall and the bottom wall of the mounting groove 54, respectively. Since the mounting groove 54 is provided on the top wall of the soundproof box 11, the noise generated by the driving member 3 in the soundproof box 11 during operation is easily transmitted outward through the mounting groove 54. By providing the first soundproof board 51 and the second soundproof board 52, it is beneficial to improve the sealing of the soundproof box 11, thereby further facilitating the isolation of the noise generated by the driving member 3, reducing the possibility of its interference with the detection of the component 9 to be detected, and further improving the accuracy and objectivity of the detection result.

[0110] The first swing arm 41 is movably connected to the first sound insulation board 51, and the second swing arm 42 is movably connected to the second sound insulation board 52. Specifically, corresponding slide grooves (not shown in the figure) can be provided on the first sound insulation board 51 and the second sound insulation board 52, and the first swing arm 41 and the second swing arm 42 can cooperate with the first sound insulation board 51 and the second sound insulation board 52 through the corresponding slide grooves, thereby realizing the movable connection between the first swing arm 41 and the first sound insulation board 51 and the second cover plate and the second sound insulation board 52.

[0111] The connecting member 43 is located between the first sound insulation board 51 and the second sound insulation board 52, and can move relative to the first sound insulation board 51 and the second sound insulation board 52. The first sound insulation board 51 and the second sound insulation board 52 also limit the connecting member 43, reducing the possibility of the connecting member 43 coming out of the installation groove 54, so as to improve the stability of the connection between the first swing rod 41, the second swing rod 42 and the connecting member 43. When the second swing rod 42 drives the connecting member 43 to move, the connecting member 43 will also generate a certain amount of noise. Since the first sound insulation board 51 and the second sound insulation board 52 have good sound insulation effects, the possibility of the noise generated by the connecting member 43 being transmitted to the part to be detected 9 and interfering with the detection of the part to be detected 9 is reduced. Therefore, by setting the first sound insulation board 51 and the second sound insulation board 52, it is helpful to improve the accuracy of the abnormal sound detection device.

[0112] like Figure 2 As shown, in a possible implementation, the sound insulation installation platform 5 further includes at least one fastener 53, the fastener 53 may be a bolt, and the number of the fasteners 53 may be one, two, three, four or more. Figure 3 , the first sound insulation board 51 and the second sound insulation board 52 are connected to the top wall of the sound insulation box 11 through the above-mentioned fasteners 53. Such a design is conducive to improving the stability and reliability of the connection between the first sound insulation board 51, the second sound insulation board 52 and the sound insulation box 11, that is, it is conducive to improving the stability of the entire sound insulation installation platform 5 installed on the sound insulation box 11, reducing the possibility of the first sound insulation board 51 and the second sound insulation board 52 falling off from the sound insulation box 11, thereby facilitating the stability of the connection member 43 placed in the sound insulation installation platform 5, and at the same time, it is also conducive to improving the stability of the connection between the first swing arm 41, the second swing arm 42 and the sound insulation installation platform 5, and then it is conducive to realizing the overall smooth and smooth movement of the swing member 4.

[0113] like Figure 4 As shown, in a possible implementation, the first swing rod 41 has a first contact portion 411, which is located at the bottom of the first swing rod 41, and the second swing rod 42 has a second contact portion 421, which is located at the top of the second swing rod 42, wherein the first contact portion 411 and the second contact portion 421 are both spherical structures. Please also refer to Figure 3, the first contact part 411 is movably connected to the connecting member 43 and the first sound insulation board 51, and the second contact part 421 is movably connected to the connecting member 43 and the second sound insulation board 52. Such a design is conducive to achieving stable and smooth movement of the first swing rod 41 and the second swing rod 42. Specifically, under the action of the driving member 3, the first swing rod 41 and the second swing rod 42 can achieve reciprocating swinging motion. Therefore, by setting the first contact part 411, it is conducive to achieving relative movement between the first swing rod 41 and the connecting member 43 and the first sound insulation board 51, and it is conducive to improving the stability and smoothness of the swing of the first swing rod 41. Similarly, by setting the second contact part 421, it is conducive to improving the stability and smoothness of the swing of the second swing rod 42, thereby facilitating improving the reliability of the entire swing member 4.

[0114] In this embodiment, the first rocker arm 41 may have a first matching portion 412 connected to the connecting member 43, and the first matching portion 412 may be connected to the first contact portion 411; the second rocker arm 42 may have a second matching portion 422 connected to the connecting member 43, and the second matching portion 422 may be connected to the first contact portion 411.

[0115] like Figure 6 As shown, the abnormal sound detection device of the embodiment of the present application drives the swing member 4 to move through the driving member 3, and then drives the member to be detected 9 to move, so as to simulate the scene when the member to be detected 9 shakes under normal use. The existing abnormal sound detection equipment can only realize the movement of the member to be detected in a single direction, such as only being able to swing the member to be detected left and right, or only being able to swing forward and backward, that is, the detection direction of the existing abnormal sound detection equipment is relatively single, resulting in low detection accuracy and prone to errors. For example, when shaking, some parts in the member to be detected will only collide with each other in the left and right directions to produce abnormal sounds, while other parts will only collide with each other in the front and back directions to produce abnormal sounds. At this time, it is difficult to fully reflect the real abnormal sound problem of the member to be detected by only detecting in a single direction, thereby affecting the objectivity and accuracy of the detection. To address this problem, the driving member 3 in the embodiment of the present application can realize the movement of the part to be detected 9 in two different directions, namely, a first direction and a second direction. The first direction can be parallel to the length direction X of the shell 1, and the second direction can be parallel to the width direction Y of the shell 1. Even if the part to be detected 9 can move in the left and right directions and in the front and back directions, such a design is conducive to expanding the detection range of the abnormal sound detection device and reducing detection errors, thereby helping to improve the accuracy and objectivity of the detection.

[0116] like Figure 7 As shown, in a possible implementation, the driving member 3 includes a first driving member 31, and the first driving member 31 can be a motor or other driving components such as a motor. Figure 6The first driving member 31 is connected to the swing member 4 to drive the swing member 4 to drive the detection member 9 to move along the first direction. The first direction is parallel to the length direction X of the housing 1, that is, the detection member 9 can swing left and right.

[0117] The first driving member 31 can be electrically connected to an external device (not shown in the figure) to power the first driving member 31 and control the speed and direction of the operation of the first driving member 31. By providing the first driving member 31, it is beneficial to realize the swing of the member to be detected 9 in the first direction, so that the abnormal sound detection device can simulate the scene where the member to be detected 9 is used in a shaking state, and then it is convenient to detect the abnormal sound caused by the shaking of the member to be detected 9.

[0118] like Figure 7 As shown, in a possible embodiment, the abnormal sound detection device also includes a first transmission member 71 and a second transmission member 72. The first transmission member 71 and the second transmission member 72 are both located on the side of the swing member 4 close to the first driving member 31. The first transmission member 71 is connected to the first driving member 31, and the second transmission member 72 is meshed with the first transmission member 71 and connected to the second rocker rod 42.

[0119] Specifically, the first transmission member 71 and the second transmission member 72 can be driven by a worm gear, the first transmission member 71 can be a worm, the second transmission member 72 is a gear that can mesh with the worm, the first transmission member 71 is arranged along the length direction X of the housing 1, and the second transmission member 72 is located above the first transmission member 71 along the height direction Z of the housing 1. This transmission method has high stability and reliability. At the same time, the overall structure of the first transmission member 71 and the second transmission member 72 is relatively compact, and the noise generated is relatively small. The above design is conducive to realizing the swing of the member to be detected 9 in the first direction, and is conducive to improving the stability of the swing of the member to be detected 9, thereby helping to improve the accuracy of detection.

[0120] like Figure 7 As shown, in a possible embodiment, the abnormal sound detection device also includes a first bracket 44, and the first bracket 44 can be a U-shaped bracket, which can be made of metal material; a portion of the second transmission member 72 can extend into the first bracket 44, so that the structure inside the sound insulation box 11 is more compact, which is beneficial to saving the volume of the sound insulation box 11.

[0121] The first bracket 44 is located on a side of the second swing rod 42 close to the second transmission member 72. One end of the first bracket 44 is connected to the second swing rod 42, and the other end is connected to the second transmission member 72, so that the second transmission member 72 drives the second swing rod 42 to move through the first bracket 44. Specifically, the upper end of the first bracket 44 is fixedly connected to the second swing rod 42, and the lower end of the first bracket 44 is fixedly connected to the second transmission member 72. Therefore, when the first driving member 31 drives the second transmission member 72 to rotate through the first transmission member 71, the second transmission member 72 can drive the swing member 4 to swing along the first direction through the first bracket 44. By setting the first bracket 44, it is conducive to realize the connection between the second transmission member 72 and the swing member 4, so as to realize the swing of the to-be-detected member 9 in the first direction. At the same time, such a setting is also conducive to improving the stability of the connection between the second transmission member 72 and the second swing rod 42, so as to improve the stability of the movement of the entire swing member 4, and then to improve the stability of the movement of the to-be-detected member 9.

[0122] like Figure 7 As shown, in a possible embodiment, the driving member 3 also includes a second driving member 32, and the second driving member 32 can be a motor, or other driving components such as a motor. The second driving member 32 is connected to the swinging member 4, and drives the detection member 2 to swing along the second direction. Similarly, the second driving member 32 can be electrically connected to an external device (not shown in the figure), so as to power the second driving member 32, and control the speed, direction, etc. of the operation of the second driving member 32. By arranging the second driving member 32, the swing of the detection member 9 in the second direction can be realized, so that the driving member 3 as a whole can realize the swing of the detection member 9 in two directions, which is conducive to enabling the staff to adjust the swing direction of the detection member 9 according to the actual detection requirements, so as to obtain objective and accurate detection results, and at the same time, such a design is also conducive to improving the flexibility of the use of the abnormal sound detection device, so as to improve the scope of application of the abnormal sound detection device.

[0123] The second driving member 32 is located at one side of the first driving member 31. Specifically, the second driving member 32 can be arranged side by side with the first driving member 31, and the second driving member 32 can have a certain interval with the first transmission member 71. The second direction intersects with the first direction. Specifically, the second direction can be parallel to the width direction Y of the housing 1, that is, the member to be detected 9 can swing back and forth.

[0124] like Figure 7As shown, in a possible implementation, the abnormal sound detection device includes a second bracket 45, the second bracket 45 is located on the side of the first bracket 44 away from the second swing rod 42, one end of the second bracket 45 is rotatably connected to the first bracket 44, and the other end is connected to the second driving member 32. When the first driving member 31 is in operation, the second bracket 45 is in a stationary rotation because it is not affected by the first driving member 31, and since the first bracket 44 and the second bracket 45 are rotatably connected together, the first bracket 44 can swing along the first direction driven by the first transmission member 71 and the second transmission member 72; and when the second driving member 32 is in operation, the second driving member 32 can directly drive the second bracket 45 to swing along the second direction, and the second bracket 45 drives the swinging member 4 to swing through the first bracket 44, thereby realizing the swinging of the swinging member 4 in the second direction. By setting the second bracket 45, it is helpful to improve the stability of the connection between the second driving member 32 and the swinging member 4, thereby facilitating the swinging of the swinging member 4 in the second direction, wherein the second bracket 45 is rotatably connected to the first bracket 44. Such a design is conducive to the swinging of the member to be detected 9 in the first direction and the second direction, thereby facilitating the objectivity and accuracy of the detection of the abnormal sound detection device.

[0125] For details, please refer to Figure 7 The second bracket 45 includes a first main body 451 and a second main body 452. The second main body 452 is rotatably connected to the first bracket 44, and the second main body 452 is connected to the second driving member 32 through the first main body 451. The second main body 452 can be a "mouth"-shaped structure, and the second transmission member 72 can extend into the second main body 452. This design is conducive to realizing a compact design between each transmission member and each bracket. The first main body 451 extends along the height direction Z of the housing 1, which is conducive to improving the installation position of the second main body 452, thereby reducing the possibility of interference between the second main body 452 and the first transmission member 71, resulting in the first transmission member 71 not being able to work normally.

[0126] like Figure 7 As shown, in a possible embodiment, a fitting member 6 is sleeved on the first transmission member 71, and the fitting member 6 has an annular structure and can be a metal member. The fitting member 6 can rotate relative to the first transmission member 71, and the second bracket 45 is rotatably connected to the first transmission member 71 through the fitting member 6. By providing the fitting member 6, it is beneficial to realize the connection between the second bracket 45 and the first transmission member 71. Such a design improves the stability of the installation of the second bracket 45, reduces the possibility of the second bracket 45 shaking and thus causing the movement stability of the swing member 4 to decrease. At the same time, such a design is beneficial to improve the compactness of the internal structure of the sound insulation box 11, thereby saving the volume of the sound insulation box 11, and further saving the volume of the entire abnormal sound detection device.

[0127] Among them, the first driving member 31 and the second driving member 32 can be arranged along the length direction X of the shell 1. Along the length direction X of the shell 1, one end of the second bracket 45 can be directly connected to the second driving member 32, and the other end can be mounted on the first transmission member 71 through the matching member 6. When the second bracket 45 swings back and forth along the second direction under the action of the second driving member 32, the second bracket 45 can also move relative to the first transmission member 71 under the action of the matching member 6.

[0128] As can be seen from the above, the abnormal sound detection device in the embodiment of the present application realizes the movement of the to-be-detected member 9 in the first direction and the second direction by setting two driving devices, the first driving member 31 and the second driving member 32. As the number of driving devices increases, the noise during operation will also increase accordingly. Considering this problem, the abnormal sound detection device in the embodiment of the present application simultaneously shields and isolates the operation noise of the first driving member 31 and the second driving member 32 by setting a soundproof box 11, so that the abnormal sound detection device can realize the movement of the to-be-detected member 9 in multiple directions, and also reduce the possibility of interference of each driving member on the detection of the to-be-detected member 9, further improving the accuracy of the detection.

[0129] like Figure 6 As shown, in a possible implementation, the abnormal sound detection device further includes a clamping member 8, which is disposed on a side of the swinging member 4 away from the driving member 3 and is movably connected to the swinging member 4, and is used to clamp the member to be detected 9.

[0130] The clamping member 8 plays a role of clamping and fixing the part to be detected 9. Specifically, the clamping member 8 can adjust its own size to clamp the parts to be detected 9 of different sizes. The clamping member 8 can move relative to the swinging member 4, so that the posture of the part to be detected 9 can be adjusted according to different needs to improve the accuracy and objectivity of detection. By providing the clamping member 8, it is beneficial to fix the part to be detected 9 inside the abnormal sound detection device, thereby reducing the possibility of the part to be detected 9 falling off the swinging member 4 during the swinging process. By adjusting the position of the clamping member 8, the posture of the part to be detected 9 can be adjusted, which is further beneficial to improve the flexibility of the use of the abnormal sound detection device and facilitate the detection work of the abnormal sound detection device.

[0131] like Figure 8 As shown, in a possible implementation, the detection element 2 includes at least one sensor 21, which can be a sound sensor, which can collect the abnormal sound emitted by the detection element 9 to realize the detection function of the abnormal sound detection device. The sensor 21 can be electrically connected to an external device such as a (processor), so as to send the collected relevant data to the external device (not shown in the figure) for analysis and judgment to obtain the detection result.

[0132] Among them, the sensor 21 can move relative to the part to be detected 9. Specifically, the sensor 21 can move along the length direction X or the width direction Y of the shell 1 to adjust the relative position between itself and the part to be detected 9, so as to facilitate the collection of abnormal sounds emitted by the part to be detected 9. At the same time, the sensor 21 can also move along the height direction Z of the shell 1 to shorten the distance between itself and the part to be detected 9, so that the sensor 21 can collect clearer sound data to improve the accuracy of detection of the abnormal sound detection device.

[0133] The number of the sensing elements 21 may be one, two, three or more. By providing a plurality of sensing elements 21, it is advantageous to more comprehensively collect abnormal sounds emitted by the detection element 9, thereby facilitating improving the accuracy of the detection result.

[0134] like Figure 8 As shown, in a possible implementation, the detection member 2 further includes at least one guide rail 22 , the guide rail 22 is connected to the housing 1 , and the sensor 21 is connected to the corresponding guide rail 22 , so that the sensor 21 can move along the guide rail 22 .

[0135] The guide rail 22 can be welded to the inner surface of the top wall of the housing 1, or can be installed on the top wall of the housing 1 by screws and other parts. Specifically, the guide rail 22 can be set along the length direction X or the width direction Y of the housing 1. The number of guide rails 22 corresponds to the number of sensors 21, so that each sensor 21 can move along the corresponding guide rail 22, thereby reducing the possibility of interference and collision between multiple sensors 21 during movement. By setting the guide rail 22, it is helpful to improve the stability of the movement of the sensor 21, and then it is helpful to improve the reliability of the entire abnormal sound detection device.

[0136] like Figure 8 As shown, in a possible embodiment, the detection member 2 also includes at least one connecting rod 23, which can be a rod-shaped member; the sensor member 21 is connected to the guide rail 22 via the corresponding connecting rod 23, that is, the connecting rod 23 can play a connecting role. The setting of the connecting rod 23 is beneficial to improving the stability and reliability of the connection between the sensor member 21 and the guide rail 22, thereby facilitating the smooth movement of the sensor member 21.

[0137] The sensor 21 can move relative to the connecting rod 23 to adjust its posture. The sensor 21 adjusts its posture to meet different detection requirements, thereby improving the accuracy of detection and further improving the reliability of the abnormal sound detection device.

[0138] Specifically, the connecting rod 23 can also be a rod-shaped component with an adjustment function, which can adjust the position of the sensor 21 in the height direction Z of the shell 1 by adjusting its own size, thereby facilitating the adjustment of the distance between the sensor 21 and the component to be detected 9, so that the sensor 21 can collect clear sound data.

[0139] It can be seen from the above that the abnormal sound detection device provided in the embodiment of the present application can detect the abnormal sound of the part to be detected 9 in a static state and in a moving state, that is, the abnormal sound detection device can perform shaking abnormal sound detection and background noise abnormal sound detection on the part to be detected 9.

[0140] Among them, the method for detecting abnormal noise during shaking is as follows: open the shell 1 and put in the part to be detected 9, and fix the part to be detected 9 by the clamping part 8, wherein the position of the clamping part 8 can be adjusted according to the specific requirements of the detection to adjust the posture of the part to be detected 9; the abnormal noise detection device has an external device electrically connected to the detection part 2, and the position and posture of the sensor 21 can be adjusted by operating the external device; the driving part 3 can also be electrically connected to the above-mentioned external device, and the driving part 3 can be controlled by operating the external device so that the swinging part 4 drives the part to be detected 9 to swing according to the preset direction, speed and frequency; when the part to be detected 9 is shaking, relevant sound data is collected by the sensor 21, and the sound data is sent to the external device, and the external device can analyze and judge the sound data to obtain the final detection result.

[0141] The detection method of background noise is roughly similar to the detection method of shaking noise. The difference is that the detection of background noise requires the detection of abnormal noise emitted by the detected part 9 in a static working state. Therefore, when performing the detection, the driving part 3 does not need to drive the swinging part 4 to move. The following is an example of detecting the background noise emitted by the camera module in the mobile phone: First, the camera device in the mobile phone needs to be turned on and put it in working state, and then the shell 1 is opened to put the mobile phone on the clamping part 8, and according to the actual detection requirements, the position of the clamping part 8 and the sensor 21 is adjusted, and the background noise emitted by the mobile phone is collected through the sensor 21. Finally, the external equipment analyzes and judges the data collected by the sensor 21 to obtain the final detection result.

[0142] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
