Among these trends, in-vehicle screens come in various designs, such as rotating screens, pop-up screens, ceiling-mounted screens, and sliding screens, providing users with more interactive experiences and ways to use them. Typically, in-vehicle screens generate some noise during use (e.g., flipping or folding). To avoid excessive noise affecting the experience of passengers, it is necessary to test the noise level of the in-vehicle screen during operation.

[0003] In related technologies, vehicle screen noise testing equipment includes a soundproof box, a sliding table, a testing fixture, and a drive mechanism. The testing fixture is fixed on the sliding table, and the drive mechanism drives the sliding table to slide inside the soundproof box. In use, the box door is opened, the sliding table is first pushed out of the soundproof box by the drive mechanism, the vehicle screen is then installed on the testing fixture, the sliding table is then pulled into the soundproof box by the drive mechanism, and finally the box door is closed to test the vehicle screen.

[0004] However, the slide has a limited extension distance. After the vehicle screen is installed on the testing fixture, its position is fixed and cannot be placed in the middle of the soundproof box, resulting in poor testing results for the vehicle screen. Utility Model Content

[0050] An embodiment of the first aspect of this application provides a vehicle-mounted screen noise detection device. Please refer to... Figure 1 , Figure 8 and Figure 9 The vehicle screen noise detection device 100 includes a soundproof box 10, a first slide 20, a second slide 30, a testing fixture 40, a first drive mechanism 211, a second drive mechanism 311, and a noise collector 50. The first slide 20 is slidably mounted inside the soundproof box 10 along a first direction X, and the second slide 30 is slidably mounted on the first slide 20 along the first direction X. The first drive mechanism 211 is connected between the soundproof box 10 and the first slide 20 to drive the first slide 20 to slide within the soundproof box 10. The second drive mechanism 311 is connected between the first slide 20 and the second slide 30 to drive the second slide 30 to slide on the first slide 20. The testing fixture 40 is fixed on the second slide 30 and is used to mount the vehicle screen 200 to be tested. The noise collector 50 is located inside the soundproof box 10 and is used to collect the noise generated during the use of the vehicle screen 200.

[0051] The function of the soundproof enclosure 10 is to isolate external noise and prevent it from affecting the noise detection of the vehicle screen 200 inside the soundproof enclosure 10. Optionally, the noise level of the soundproof enclosure 10 is less than or equal to 30 dB.

[0052] The first slide table 20 is slidably installed in the soundproof box 10 along the first direction X; optionally, the first slide table 20 is provided with a third slide rail 212 arranged along the first direction X, and the soundproof box 10 is provided with a first slide seat 214. The first slide table 20 is slidably installed in the soundproof box 10 along the first direction X through the sliding cooperation of the third slide rail 212 and the first slide seat 214.

[0053] The second slide 30 is slidably mounted on the first slide 20 along the first direction X; optionally, the first slide 20 is provided with a fourth slide rail 213 arranged along the first direction X, and the second slide 30 is provided with a second slide block. The second slide 30 is slidably mounted on the first slide 20 along the first direction X through the sliding cooperation of the fourth slide rail 213 and the second slide block.

[0054] A first drive mechanism 211 is connected between the soundproof box 10 and the first slide 20 to drive the first slide 20 to slide within the soundproof box 10. Optionally, the first drive mechanism 211 is a first telescopic cylinder, which is arranged along a first direction X. The first telescopic cylinder includes a first cylinder body and a first telescopic rod that extends and retracts within the first cylinder body. The first cylinder body is connected to the soundproof box 10, and the first telescopic rod is connected to the first slide 20. The extension and retraction of the first telescopic rod within the first cylinder body drives the first slide 20 to slide within the soundproof box 10 along the first direction X. During the sliding process of the first slide 20, two states can be formed: product loading / unloading and testing.

[0055] The second drive mechanism 311 is connected between the first slide 20 and the second slide 30 to drive the second slide 30 to slide on the first slide 20. Optionally, the second drive mechanism 311 is a second telescopic cylinder, which is arranged along the first direction X. The second telescopic cylinder includes a second cylinder body and a second telescopic rod that extends and retracts within the second cylinder body. The second cylinder body is connected to the first slide 20, and the second telescopic rod is connected to the second slide 30. The second telescopic rod extends and retracts within the second cylinder body to drive the second slide 30 to slide along the first direction X on the first slide 20. During the sliding process, the second slide 30 mainly assists the first slide 20 in picking up and placing products in appropriate positions and testing them in reasonable locations.

[0056] The testing fixture 40 is fixed on the second slide 30, meaning that the testing fixture 40 can move along the first direction X on the first slide 20 with the second slide 30. The testing fixture 40 is used to simulate the installation state of the vehicle-mounted screen 200.

[0057] A noise collector 50 is installed inside the soundproof enclosure 10 and is used to collect noise generated during the use of the vehicle screen 200 (e.g., flipping or folding). Optionally, one or more noise collectors 50 can be installed. When multiple noise collectors 50 are installed, they can be distributed at different locations on the vehicle screen 200 to better collect noise generated during the use of the vehicle screen 200; for example, the noise collectors 50 can be installed above, below, to the left, to the right, in front of, or to the right of the vehicle screen 200.

[0058] Optionally, the noise collector 50 is a microphone.

[0059] The vehicle screen 200 can be a rotating screen, a folding screen, a ceiling-mounted screen, etc.; among them, the maximum compatible size is 900mm in length, 400mm in width, and 300mm in height.

[0060] The beneficial effects of the vehicle screen noise detection device 100 provided in this application embodiment are as follows: In use, the first slide 20 is first pushed out of the soundproof box 10 by the first drive mechanism 211, and then the vehicle screen 200 is installed on the detection fixture 40. After that, the first slide 20 is pulled into the soundproof box 10 by the first drive mechanism 211. Then, the second slide 30 is driven to slide on the first slide 20 by the second drive mechanism 311, so that the detection fixture 40 is in the middle position of the soundproof box 10, thus solving the problem of poor detection effect of the vehicle screen 200.

[0061] Among them, the vehicle-mounted screen noise detection device 100 can be connected to the workshop's MES system to monitor product information.

[0062] Please refer to Figure 9 In some embodiments, the first slide 20 includes two sliding arms 21 arranged along a first direction X, and a connecting arm 22 arranged along a second direction Y. The two ends of the connecting arm 22 are respectively connected to the two sliding arms 21, wherein the first direction X intersects the second direction Y.

[0063] Optionally, both sliding arms 21 are provided with a third slide rail 212 to ensure the stability of the first slide 20 sliding within the soundproof box 10, and / or both sliding arms 21 are provided with a fourth slide rail 213 to ensure the stability of the second slide 30 sliding on the first slide 20.

[0064] Optionally, the first direction X intersects the second direction Y perpendicularly or approximately perpendicularly.

[0065] Optionally, the second slide table 30 includes two sliding bodies 31, which slide along the first direction X on the two sliding arms 21 respectively, and the detection fixture 40 is fixed on the two sliding bodies 31.

[0066] Based on the above scheme, the two ends of the connecting arm 22 are respectively connected to two sliding arms 21, so that the first slide table 20 is U-shaped as a whole, which simplifies the structure of the first slide table 20 and ensures the structural stability of the first slide table 20.

[0067] In other embodiments, the first slide 20 may be a frame structure.

[0068] Please refer to Figure 8 In some embodiments, the vehicle screen noise detection device 100 further includes an adjustment mechanism 60 disposed in the soundproof box 10. The adjustment mechanism 60 is connected to the noise collector 50 and is used to adjust the position of the noise collector 50 relative to the vehicle screen 200.

[0069] Optionally, the adjustment mechanism 60 can adjust the position of the noise collector 50 relative to the vehicle screen 200 along the first direction X, the second direction Y, and the third direction Z.

[0070] Of course, the adjustment mechanism 60 can also adjust the position of the noise collector 50 relative to the vehicle screen 200 in one or two of the first direction X, the second direction Y, and the third direction Z. For example, the adjustment mechanism 60 can adjust the position of the noise collector 50 relative to the vehicle screen 200 only along the first direction X, the second direction Y, or the third direction Z; or, the adjustment mechanism 60 can adjust the position of the noise collector 50 relative to the vehicle screen 200 only along the first direction X and the second direction Y; or, the adjustment mechanism 60 can adjust the position of the noise collector 50 relative to the vehicle screen 200 only along the first direction X and the third direction Z; or, the adjustment mechanism 60 can adjust the position of the noise collector 50 relative to the vehicle screen 200 only along the second direction Y and the third direction Z.

[0071] It is understandable that the adjustment mechanism 60 can be a manual adjustment mechanism or an automatic adjustment mechanism.

[0072] Based on the above scheme, the position of the noise collector 50 relative to the vehicle screen 200 is adjusted by the adjustment mechanism 60 to ensure that the distance and position of the noise collector 50 and the vehicle screen 200 are appropriate, so as to better collect the noise generated during the use of the vehicle screen 200.

[0073] In other embodiments, the adjustment mechanism 60 may be omitted, and the noise collector 50 may be fixed at a predetermined position inside the soundproof box 10.

[0074] Please refer to Figure 8 In some embodiments, the vehicle screen noise detection device 100 further includes a vibration component 70 disposed in the sound insulation box 10. The vibration component 70 includes a third drive mechanism 71, a buffer block 72, and a vibration sensor 73. The vibration sensor 73 is connected to the third drive mechanism 71 through the buffer block 72.

[0075] Optionally, the third drive mechanism 71 is a third telescopic cylinder arranged along the third direction Z.

[0076] The buffer block 72 can buffer the vibration sensor 73 and extend the service life of the vibration sensor 73.

[0077] Vibration sensor 73 can be attached to vehicle screen 200 to collect low-frequency noise during vehicle screen 200 use.

[0078] Please refer to Figure 3 , Figure 4 and Figure 6In some embodiments, the soundproof box 10 includes a soundproof outer box 11 and a soundproof inner box 12 disposed inside the soundproof outer box 11. The soundproof outer box 11 includes an outer box body 111 and an outer box door 112 movably installed on the outer box body 111. The soundproof inner box 12 includes an inner box body 121 and an inner box door 122 movably installed on the inner box body 121. The outer box door 112 and the inner box door 122 are arranged correspondingly.

[0079] Optionally, the outer door 112 moves along a third direction Z on the outer casing 111 to open or close; the inner door 122 moves along a third direction Z on the inner casing 121 to open or close.

[0080] The outer box door 112 and the inner box door 122 are arranged correspondingly. That is, after both the outer box door 112 and the inner box door 122 are opened, the first slide 20 can be pushed out from inside the soundproof box 10.

[0081] By dividing the soundproof box 10 into two layers, the outer soundproof box 11 and the inner soundproof box 12, the soundproof box 10 has better sound insulation capabilities and can better isolate external noise interference.

[0082] In other embodiments, the soundproof box 10 has only one layer. For example, the soundproof box 10 includes a soundproof outer box 11 but does not include a soundproof inner box 12; or, the soundproof box 10 includes a soundproof inner box 12 but does not include a soundproof outer box 11.

[0083] Please refer to Figure 3 In some embodiments, an air insulation layer 13 is also provided between the soundproof outer box 11 and the soundproof inner box 12.

[0084] This can be understood as a gap being left between the soundproof outer box 11 and the soundproof inner box 12, which forms an air soundproof layer 13.

[0085] Based on the above solution, by setting an air sound insulation layer 13 between the soundproof outer box 11 and the soundproof inner box 12, a three-layer sound insulation is formed, which further improves the sound insulation capability of the soundproof box 10.

[0086] In other embodiments, the air insulation layer 13 may not be provided between the soundproof outer box 11 and the soundproof inner box 12, that is, the soundproof outer box 11 and the soundproof inner box 12 are arranged in close contact.

[0087] Please refer to Figure 4 and Figure 5In some embodiments, the outer casing 111 is provided with a first slide rail 1111 arranged along the third direction Z, and the outer casing door 112 is provided with a first sliding member 1121 that slides in cooperation with the first slide rail 1111. The third direction Z is perpendicular to the first direction X. The vehicle screen noise detection device 100 also includes a fourth drive mechanism 113 disposed between the outer casing 111 and the outer casing door 112, and a first locking mechanism 114 on the outer casing 111. The first locking mechanism 114 is used to lock in cooperation with the first sliding member 1121 when the outer casing door 112 is opened, so as to lock the outer casing door 112 in the open state.

[0088] Optionally, the fourth drive mechanism 113 is a fourth telescopic cylinder arranged along the third direction Z.

[0089] Optionally, two first slide rails 1111, two first sliding members 1121, and two fourth drive mechanisms 113 are provided. In the second direction Y, the two first slide rails 1111 are respectively located on both sides of the outer box door 112, the two first sliding members 1121 are respectively located on both sides of the outer box door 112, and the two fourth drive mechanisms 113 are respectively located on both sides of the outer box door 112 to ensure the stability of the outer box door 112 when it is opened and closed.

[0090] Optionally, the first locking mechanism 114 includes a first driving member and a first locking tongue connected to the first driving member. The first driving member drives the first locking tongue to move along the second direction Y. The first sliding member 1121 is provided with a first locking groove 11211 that cooperates with the first locking tongue. When the outer door 112 is in the open state, the first driving member drives the first locking tongue to move towards the first sliding member 1121 and insert it into the first locking groove 11211 to lock the first sliding member 1121, thereby locking the outer door 112 in the open state. The first driving member can be an electromagnet, a telescopic cylinder, an electric push rod, etc.

[0091] One or more first locking mechanisms 114 may be provided; optionally, two first locking mechanisms 114 are provided, and the two first locking mechanisms 114 are respectively located on both sides of the outer box door 112.

[0092] By adopting the above technical solution, the first locking mechanism 114 can prevent the outer door 112 from falling and hitting people due to a sudden power outage.

[0093] Please refer to Figure 6 and Figure 7In some embodiments, the inner box 121 is provided with a second slide rail 1211 arranged along the third direction Z, and the inner box door 122 is provided with a second sliding member 1221 that slides with the second slide rail 1211. The third direction Z is perpendicular to the first direction X. The vehicle screen noise detection device 100 also includes a fifth drive mechanism 123 disposed between the inner box 121 and the inner box door 122, and a second locking mechanism 124 disposed on the inner box 121. The second locking mechanism 124 is used to lock with the second sliding member 1221 when the inner box door 122 is opened, so as to lock the inner box door 122 in the open state.

[0094] Optionally, the fifth drive mechanism 123 is a fifth telescopic cylinder arranged along the third direction Z.

[0095] Optionally, two second slide rails 1211, two second sliding members 1221, and two fifth drive mechanisms 123 are provided.

[0096] Optionally, the second locking mechanism 124 includes a second driving member and a second locking tongue connected to the second driving member. The second driving member drives the second locking tongue to move along the second direction Y. The second sliding member 1221 is provided with a second locking groove 12211 that cooperates with the second locking tongue. When the inner door 122 is in the open state, the second driving member drives the second locking tongue to move towards the second sliding member 1221 and insert it into the second locking groove 12211 to lock the second sliding member 1221, thereby locking the inner door 122 in the open state. The second driving member can be an electromagnet, a telescopic cylinder, an electric push rod, etc.

[0097] One or more second locking mechanisms 124 may be provided; optionally, two second locking mechanisms 124 are provided, and the two second locking mechanisms 124 are respectively located on both sides of the inner box door 122.
