Description

Technical Field

[0001] The utility model relates to the technical field related to vehicle detection, in particular to a vehicle detection device. Background Art

[0002] Vehicles are the most common means of transportation. Due to their complex mechanical structure, mechanical failures are very common. However, drivers can usually only hear abnormal noises but cannot directly understand the fault conditions. Professional auto repair personnel are needed to inspect vehicles with abnormal noises in order to determine the cause of the noises, find the faulty structure, and perform repairs.

[0003] There are many types of abnormal noises in vehicles, such as abnormal body noises, engine noises, gearbox noises, tire noises, suspension noises, etc. A comprehensive inspection of the entire vehicle is required to eliminate the faults.

[0004] When detecting a vehicle with abnormal noise, if the vehicle is parked, it is impossible to accurately detect the abnormal noise made by the vehicle when it is in motion. If a vehicle with abnormal noise is driving on the road, detecting it while the vehicle is in motion will pose a great safety hazard to the driver and other people around. However, the existing vehicle abnormal noise detection device can only detect when the vehicle is stationary or on a part of the vehicle. For example, Chinese patent publication number CN219935287U discloses a detection device for detecting abnormal noise in the front cabin of a vehicle, but the device can only detect the front cabin of the vehicle, such as detecting the engine and other components in the front cabin, and cannot perform a comprehensive detection of the entire vehicle.

[0005] Therefore, there is a problem in the prior art that the abnormal noise detection of the entire vehicle cannot be performed. Utility Model Content

[0061] Vehicles are a common means of transportation. When a mechanical failure occurs in a vehicle, abnormal noises generally occur. Common abnormal noises include body noises, engine noises, gearbox noises, suspension noises, etc. For example, body noises usually occur due to friction in the body or doors and windows. Engine noises and gearbox noises are usually related to wear of parts, gearbox bearings or gears, improper assembly or adjustment. When a vehicle makes abnormal noises, it is necessary to check it in time so that the vehicle can be repaired. For example, abnormal noises in the engine and gearbox require a comprehensive inspection of the vehicle.

[0062] Common detection methods include the rapid acceleration method, the regional knocking method, and the rack inspection method. The rapid acceleration method generally maintains low speed operation first, repeatedly increases the throttle, and listens to see if the abnormal sound increases with the increase in speed. If a vehicle with abnormal sound is driven on the road, it is detected while the vehicle is running, which poses a great safety hazard to the driver and other people around. The existing rack inspection method is to put the vehicle on the rack for inspection, but the rack inspection method cannot simulate the driving state of the vehicle, and it is difficult to find the source of the abnormal sound when the vehicle is turned off. In addition, if a vehicle with abnormal sound is driven, it is detected while the vehicle is driving, which poses a safety hazard to maintenance personnel and other people around.

[0063] Therefore, the present application discloses a vehicle detection device, which can place the vehicle to be detected on the vehicle detection device, simulate the normal driving state on the vehicle detection device, and further set a sound measuring mechanism to record and detect the sounds of different parts of the vehicle, and then analyze and judge the recording and measure whether there is a mechanical failure, so as to restore or simulate the vehicle operating conditions to the greatest extent.

[0064] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0065] The implementation method of this embodiment discloses a vehicle detection device, see Figure 1 The vehicle detection device includes a detection platform 100, a roller mechanism 200, a sound detection mechanism 300 and an anti-slip mechanism 400.

[0066] The vehicle 600 to be inspected is parked on the table 110 of the inspection platform 100. The roller mechanism 200 includes two sets of roller assemblies 210 disposed in the inspection platform 100 and exposed from the table 110. The two sets of roller assemblies 210 are disposed at intervals along the length direction of the inspection platform 100, and the two sets of roller assemblies 210 are respectively adapted to the front and rear wheels of the vehicle 600 to be inspected.

[0067] The sound detection mechanism 300 is arranged on the detection platform 100 and is located on the side of the vehicle 600 to be detected. The anti-slip mechanism 400 includes two sets of anti-slip components 410, which are respectively located on the outside of the two sets of roller components 210 in the length direction of the detection platform 100, and the two sets of anti-slip components 410 are respectively connected to the front end and the rear end of the vehicle 600 to be detected. Figure 1 Shown in direction A.

[0068] Specifically, in this embodiment, see Figure 1 Two groups of roller assemblies 210 are provided to respectively correspond to the front and rear wheels of the vehicle 600 to be tested. Those skilled in the art should understand that, in order to ensure that the vehicle 600 to be tested can simulate the driving state on the testing platform 100, each group of roller assemblies 210 needs to be provided with two rollers or rotating shafts arranged at intervals, so that the wheels can rotate on the roller assemblies 210, but the vehicle is relatively stationary on the table 110 of the testing platform 100.

[0069] The sound measuring mechanism 300 may be a common sound tester, a recorder, a sound measuring column, etc. Those skilled in the art may design and select the sound measuring mechanism 300 according to actual needs, and this embodiment does not specifically limit this.

[0070] The two sets of anti-slip components 410 are respectively located on the outside of the two sets of roller components 210 in the length direction of the testing platform 100. The two sets of anti-slip components 410 can respectively fix the front and rear ends of the vehicle. The anti-slip components 410 can be common anti-slip hooks, anti-slip ropes, winch hooks, etc.

[0071] Furthermore, when the vehicle detection device disclosed in this embodiment is used, the vehicle with mechanical abnormal noise or to be detected is transferred to the table 110 of the detection platform 100, and the front and rear wheels of the vehicle are placed on the corresponding two groups of roller assemblies 210, and the front and rear ends of the vehicle are fixed with two groups of anti-detachment assemblies 410 to prevent detachment, so that the vehicle can simulate road driving conditions on the detection platform 100, and detect mechanical abnormal noises when the vehicle is in motion. While the actual operation of the vehicle can be completely restored, it can also avoid driving a vehicle with mechanical failure on the road in order to detect vehicle abnormal noises, thereby ensuring the safety of the driver and other people around. More specifically, the two groups of anti-detachment assemblies 410 are respectively adapted to be connected with the front and rear ends of the vehicle 600 to be detected, and can assist in traction or anti-detachment positioning of the vehicle 600 to be detected, so as to prevent the vehicle 600 to be detected from simulating driving on the detection platform 100 and rushing out of the detection platform 100, causing harm to the operator. The sound measuring mechanism 300 records and detects the sounds of different parts of the vehicle when they are running, and then professional maintenance personnel conduct professional analysis on the recorded sounds to determine whether there is a mechanical failure in the vehicle.

[0072] Next, the specific structure of the detection platform 100 is explained:

[0073] The embodiment of the utility model also discloses a vehicle detection device, see Figure 1 as well as Figure 2 The testing platform 100 is in a stepped shape as a whole, the middle part of the testing platform 100 is a plane extending in the horizontal direction, and both sides of the length direction of the testing platform 100 have inclined surfaces 130. The inclined surfaces 130 are provided to facilitate vehicles to drive onto the table 110 of the testing platform 100.

[0074] Next, the specific structure of the roller mechanism 200 is explained in detail:

[0075] See also Figure 1 to Figure 3 In the vehicle detection device disclosed in this embodiment, two roller mounting grooves 120 are provided on the table 110 of the detection platform 100, and two groups of roller assemblies 210 are rotatably disposed in the corresponding roller mounting grooves 120. Each group of roller assemblies 210 includes two rotating rollers 211, which are parallel to each other and spaced apart and disposed in the roller mounting grooves 120. For further information, see Figure 4 Each rotating roller 211 includes a rotating shaft 212 and a rotating roller 213 , and the rotating roller 213 is fixedly sleeved on the outer wall of the rotating shaft 212 .

[0076] Each rotating roller 211 is arranged along the width direction of the detection platform 100. Figure 1 As shown in the direction B, the rotating roller 211 is extended in the roller shaft installation groove 120, and two rotating shaft holes (not shown in the figure) are arranged at intervals on both side walls of the roller shaft installation groove 120. The rotating shafts 212 of the two rotating rollers 211 are rotatably arranged in the two rotating shaft holes, and one end of each rotating shaft 212 passes through one side wall where the rotating shaft hole is located and protrudes from one side of the detection platform 100. In addition, the wheels of the vehicle 600 to be detected on the detection platform 100 are respectively positioned on the corresponding roller shaft assembly 210.

[0077] It should be noted that the corresponding reference Figure 4 and Figure 5 , one end of each rotating shaft 212 passes through one of the side walls where the rotating shaft hole is located and protrudes from one side of the detection platform 100, so that after the rotating shaft 212 protrudes from the detection platform 100, it is locked and controlled by the locking mechanism for each rotating roller 211, and the rotating shaft 212 protruding from one side of the detection platform 100 is controlled by the locking mechanism, thereby controlling each rotating roller 211 to switch between the rotating state and the locked state. Those skilled in the art should understand that the roller assembly 210 can also be set as a roller, a roller wheel, etc. commonly used in the art, and this embodiment will not be repeated.

[0078] Through this structural design, each group of roller assemblies 210 includes two rotating rollers 211 that are parallel and spaced apart in the roller mounting groove 120. When the vehicle simulates a driving condition, the two rotating rollers 211 rotate and the front and rear wheels of the vehicle also rotate, which is convenient for checking whether there is a mechanical fault in the driving state.

[0079] Next, the specific structure of the anti-slip mechanism 400 is explained in detail:

[0080] The implementation method of this embodiment also discloses a vehicle detection device, see Figure 2 and Figure 3 On the table 110 of the testing table 100, anti-slip installation grooves 140 are also provided along the length direction of the testing table 100 and on the outer sides of the two roller shaft assemblies 210. Each anti-slip assembly 410 includes a capstan 411, a capstan shaft 412, a rocker 413, a traction rope 414 and a hook 415. Among them:

[0081] The winch 411 and the winch shaft 412 are located inside the test bench 100 and at corresponding positions below the corresponding anti-slip installation groove 140. The winch 411 is fixedly arranged on the winch shaft 412, and the rocker 413 is fixedly arranged at one end of the winch shaft 412. Along the length direction of the winch shaft 412, both side walls of the anti-slip installation groove 140 are provided with rotation shaft holes (not shown in the figure), and the winch shaft 412 is rotatably arranged in the rotation shaft hole. One end of the rocker 413 provided on the winch shaft 412 passes through one of the side walls where the rotation shaft hole is located and protrudes from one side of the test bench 100; the traction rope 414 is wound around the outer periphery of the winch 411, and the hook 415 is fixedly arranged at one end of the traction rope 414. The hook 415 and part of the traction rope 414 extend out of the corresponding anti-slip installation groove 140. In addition, the front end or the rear end of the vehicle 600 to be tested on the test bench 100 is respectively hooked with the corresponding hook 415.

[0082] It should be noted that the traction rope 414 and the hook 415 are only one specific implementation of the anti-slip mechanism 400. Those skilled in the art can set it to other structures according to actual needs, such as a traction rope plus a hook, a traction rope plus a hook, etc. Similarly, the winch 411, the winch shaft 412 and the rocker 413 can also be set to a motor plus a winch and a winch shaft. In the implementation disclosed in this embodiment, the winch 411 can be driven to rotate by shaking the winch shaft 412 through the rocker 413, thereby adjusting the length of the traction rope 414 wound on the winch 411. The traction rope 414 can be retracted and released during the process of fixing the vehicle, and the traction rope 414 can be adjusted to a suitable length, which has the advantages of simple structure, convenient operation and low cost.

[0083] Next, the specific structure of the locking mechanism is explained in detail:

[0084] The implementation method of this embodiment also discloses a vehicle detection device, see Figure 1 and Figure 4 , and also includes a locking mechanism arranged on one side of the detection platform 100, which is transmission-connected to the end of the rotating shaft 212 of each roller assembly 210 protruding from one side of the detection platform 100, and the end of the capstan rotating shaft 412 of each anti-slip assembly 410, and the locking mechanism controls the roller assembly 210 and the anti-slip assembly 410 to switch between a rotating state and a fixed state.

[0085] See also Figure 1 In one preferred embodiment, the locking mechanism includes two locking assemblies 500 spaced apart in the length direction of the testing platform 100, each locking assembly 500 corresponds to a group of roller assemblies 210 and a group of anti-detachment assemblies 410 on the same side in the length direction, that is, one locking assembly 500 corresponds to controlling a group of roller assemblies 210 and a group of anti-detachment assemblies 410, and each locking assembly 500 includes a telescopic driving part 510, a linkage rod 520, a first clamping part and a second clamping part 540.

[0086] See 4 and Figure 5 A telescopic rod 511 is provided at the output end of the telescopic driving part 510, and the telescopic rod 511 is fixedly connected to the opposite end of the linkage rod 520. The first clamping part and the second clamping part 540 are arranged on the linkage rod 520 at intervals. The telescopic rod 511 and the linkage rod 520 are both extended along the length direction of the detection platform 100 and span the end of the rotating shaft 212 of the corresponding roller assembly 210 and the end of the capstan rotating shaft 412 of the anti-slip assembly 410.

[0088] By adopting the above-mentioned structural design, a locking assembly 500 is provided to simultaneously control the two rotating shafts 212 of the roller assembly 210 and the capstan rotating shaft 412 of the anti-slip assembly 410. The rotating shafts 212 of the two rotating rollers 211 and the capstan rotating shaft 412 are synchronously controlled by a locking assembly 500, thereby controlling the rotating shafts 212 of the rotating rollers 211 and the capstan rotating shaft 412 to switch between the clamping locking and unlocking states.

[0089] Further preferably, the telescopic drive part 510 can be provided with a common hydraulic cylinder, telescopic cylinder, air cylinder or other structure, and each of the first clamping member 530 and the second clamping part 540 includes a movable clamping block 531 and a fixed clamping block 532, and the movable clamping block 531 and the fixed clamping block 532 are arranged on the circumferential side of the end of the corresponding rotating shaft 212, and the movable clamping block 531 and the fixed clamping block 532 are generally annular in shape in the clamped state, and the inner side walls of the movable clamping block 531 and the fixed clamping block 532 are respectively adapted to the outer side walls of the end of the corresponding rotating shaft 212, and the fixed clamping block 532 is fixedly arranged on one side of the rotating shaft 212. In addition, the movable clamping blocks 531 of the first clamping part and the second clamping part 540 are fixedly arranged on the linkage rod 520, and the linkage rod 520 drives the movable clamping blocks 531 of the first clamping part and the second clamping part 540 to move relative to the rotating shaft 212, so that the movable clamping blocks 531 of the first clamping part and the second clamping part 540 are switched between a relaxed state and a clamped state relative to the corresponding end of the rotating shaft 212.

[0090] In one of the settings or implementations, for example, when the capstan shaft 412 of the anti-slip assembly 410 and the shaft 212 of the rotating roller 211 need to be clamped or relaxed synchronously, the movable clamping block 531 of the first clamping member 530 and the second clamping portion 540 can be set on the same side of the linkage rod 520. When the clamping and relaxing states of the capstan shaft 412 and the shaft 212 of the rotating roller 211 need to be opposite, for example, when the capstan shaft 412 is in the clamped state, the shaft 212 of the rotating roller 211 needs to be relaxed or when the capstan shaft 412 is in the relaxed state, the shaft 212 of the rotating roller 211 needs to be clamped, in this case, the setting positions of the movable clamping block 531 of the first clamping member 530 and the movable clamping block 531 of the second clamping portion 540 can be adjusted. For example Figure 5 In one implementation shown, the movable clamping block 531 of the first clamping member 530 is arranged above the linkage rod 520, and the movable clamping block 531 of the second clamping portion 540 is arranged below the linkage rod 520. With this structural design, when the linkage rod 520 drives the movable clamping block 531 of the second clamping portion 540 and the winch shaft 412 to clamp, the movable clamping block 531 of the first clamping member 530 loosens the shaft 212 of the rotating roller 211. When the vehicle is tested in a specific working condition, the winch shaft 412 is clamped so that the traction rope 414 and the hook 415 fix the vehicle, and the shaft 212 of the rotating roller 211 is in a relaxed rotation state for rotation testing. Those skilled in the art can adjust and control according to actual needs, and this embodiment does not make a sole limitation on this.

[0091] Further preferably, the inner side walls of the movable clamp block 531 and / or the fixed clamp block 532 are both installed with friction plates (not shown in the figure). For example, friction plates are installed on the inner side walls of both the movable clamp block 531 and the fixed clamp block 532, or only the inner side wall of the movable clamp block 531 is installed with the friction plate, or only the inner side wall of the fixed clamp block 532 is installed with the friction plate. Those skilled in the art can make actual designs according to requirements, and this embodiment does not specifically limit this.

[0092] With this structural design, each of the first clamping member 530 and the second clamping portion 540 includes a movable clamping block 531 and a fixed clamping block 532. When the rotating shaft 212 of the rotating roller 211 and the capstan shaft 412 need to be controlled by the locking assembly 500 to switch between the relaxed state and the clamped state, the hydraulic cylinder or the air cylinder drives the linkage rod 520 to move so that the movable clamping block 531 moves relative to the fixed clamping block 532. The control is simple, convenient and fast, and the control efficiency is higher. In addition, the inner side walls of the movable clamping block 531 and / or the fixed clamping block 532 are installed with friction plates, which can improve the clamping and fixing effect of the first clamping member 530 and the second clamping portion 540.

A hollow sound amplification cavity 313 is opened in the sound measuring column 311. A recording unit 314 is installed in the sound amplification cavity 313. A connecting rod 315 is arranged on the side of the sound measuring column 311 close to the mounting frame 321. The sound measuring column 311 is fixedly connected to the mounting frame 321 through the connecting rod 315.

[0096] The recording unit 314 can be a common recorder, recording equipment, etc., with the above-mentioned structural design, and a sound measuring mechanism 300 is set to record the sounds of different internal parts of the vehicle when it is driving or working, and the sound measuring columns 311 are all horn-shaped and can absorb sound well.
