Description

Technical Field

[0001] The present invention relates to the technical field of automobile maintenance, and particularly relates to an automobile maintenance detection method. Background Art

[0002] Automobile maintenance is a general term for automobile maintenance and repair. It is to find out the reasons for the faults of the automobile through technical means and take certain measures to eliminate the faults and restore it to a certain performance and safety standard. Automobile maintenance usually targets multiple aspects such as the engine, braking system, tires, cooling system, fuel system, exhaust system, transmission system, and suspension system.

[0003] During the maintenance and detection of the suspension system, usually the vehicle is lifted, and then the maintenance worker observes the wear conditions of components such as the shock absorber, spring, and suspension arm of the vehicle suspension system, and then judges the shock absorption effect of the vehicle suspension system. However, it is difficult to achieve accurate detection of the suspension system by means of manual observation.

[0004] Based on this, in the prior art, a large number of automobile maintenance detection and corresponding devices have also been disclosed. Among them, for example, the Chinese patent with the publication number CN117054120A discloses a new energy vehicle performance test platform and its detection method, which includes a base. An installation cavity is opened on the base. A sliding block is slidably installed on the bottom inner wall of the installation cavity. A transmission rod is rotatably installed on the sliding block. A fixed block is rotatably installed on the transmission rod. An adjustment table is installed on the fixed block. Rotating shafts are installed on both sides of the adjustment table away from each other. Two rotation holes are opened on the base, and the two rotating shafts are respectively rotatably installed in the two rotation holes.

[0005] When the above prior art is used, first, the vehicle is tested on the normal flat horizontal plane of the adjustment table, and then the adjustment table is adjusted to different angles so that the new energy vehicle performs driving performance and braking effect tests on slopes at different angles. Then, control the vibration test seat to move upward to the top, and then drive the new energy vehicle to travel on the horizontal and differently angled adjustment tables with roadblocks respectively to detect the shock absorption effect of the new energy vehicle, and at the same time, the braking effect on rough roads at different angles can also be detected.

[0006] However, the above prior art still has the following deficiencies in the process of detecting the vehicle:

[0007] 1. Since the length of the adjustment table is limited, when the vehicle travels on the adjustment table, it can only move a certain distance. Therefore, the vehicle will be restricted by the travel distance, and it is difficult to make the vehicle travel a specified distance for comprehensive detection, which will affect the detection effect of the vehicle.

[0008] 2. When the vehicle is driving on a rough road surface, its four wheels cannot move to the pothole position or the raised position simultaneously, resulting in different heights of the positions where the four wheels of the vehicle are located. However, when detecting the shock absorption effect of the vehicle using the above-mentioned existing technology, only by lifting the vibration test seat to simulate the roadblocks during vehicle driving, the two front wheels or two rear wheels of the vehicle pass over the roadblocks simultaneously, so that the wheels of the vehicle cannot be detected individually, and thus the shock absorption of the vehicle cannot be comprehensively detected.

[0009] Therefore, under the viewpoints stated above, there is still room for improvement in the existing vehicle detection means. Summary of the Invention

Detailed implementation mode

[0040] The following is combined with the attached Figures 1-9 The embodiments of the present invention will be described in detail.

[0041] The embodiment of the present application discloses an automobile maintenance detection method. It should be noted that this automobile maintenance detection method is mainly applied in the process of maintaining and detecting an automobile. In terms of technical effects, it can start the automobile and simulate its normal driving, and is not limited by distance, so as to enhance the detection effect of the automobile. Especially during the detection process, it can simulate the automobile driving on roads with different flatness, specifically including bumpy roads, potholed roads, and flat roads, so as to detect the shock absorption effect of the suspension system when the automobile is driving on different roads. Further, this automobile maintenance detection method can also convert the flatness of the road surface on which the simulated automobile is driving, so as to detect the shock absorption effect of the suspension system at different wheels of the automobile respectively, and then comprehensively detect the suspension system. Embodiment

[0042] Refer to Figure 2 And Figure 3 As shown in the figure, an automobile maintenance detection method uses the following automobile maintenance detection device. The automobile maintenance detection device includes a detection platform 1. Guide platforms 2 are installed on both sides in the length direction of the detection platform 1, and receiving grooves 3 are opened at the four corners of the upper end of the detection platform 1. A supporting unit 4 for supporting the automobile wheels is arranged in the receiving groove 3, and the supporting unit 4 includes a conveyor belt 41 for rotating with the automobile wheels.

[0043] In the specific implementation process, first drive the automobile to the upper end of the detection platform 1 so that the four wheels of the automobile are respectively located on the upper ends of multiple conveyor belts 41. Secondly, the tester starts the automobile so that the wheels of the automobile rotate on the upper ends of the conveyor belts 41. Then, the supporting unit 4 applies a jacking force to different wheels of the automobile respectively to facilitate the detection of the suspension systems of different wheels of the automobile; in addition, different road conditions can be simulated through the supporting unit 4 to simulate the detection of the suspension system during the actual driving process of the automobile.

[0044] Refer to Figure 3 AndFigure 4 As shown, in order to facilitate the detection of the suspension system of the vehicle, in this embodiment, it is possible to simulate the vehicle driving normally on roads with different flatness levels, so as to comprehensively detect the suspension system of the vehicle. Based on this, a supporting unit 4 is provided in this embodiment. Specifically, the supporting unit 4 further includes a support frame 42. There are two support frames 42 symmetrically arranged along the conveyor belt 41 inside the receiving groove 3. One side of the support frame 42 away from the conveyor belt 41 is connected to the inner wall of the receiving groove 3 through a horizontal plate 43.

[0045] Furthermore, in this embodiment, a plurality of support shafts 44 that abut against the inner side wall of the conveyor belt 41 are rotatably arranged between the two support frames 42 inside the same receiving groove 3. And a top support plate 45 is rotatably installed between the two support shafts 44 on the upper side in the same receiving groove 3. The top support plate 45 is slidably abutted against the inner top wall of the conveyor belt 41. The supporting unit 4 further includes a driving assembly 46 for controlling the rotation of the conveyor belt 41.

[0046] In the specific implementation process, the top support plate 45 can support the top of the conveyor belt 41. After the tester drives the vehicle to the upper end of the detection platform 1, the four wheels of the vehicle respectively move to the upper end of the corresponding conveyor belt 41. At this time, a plurality of top support plates 45 can provide a supporting force for the conveyor belt 41. Subsequently, the tester starts the vehicle to make the vehicle wheels rotate. At the same time, the driving assembly 46 is used to control the conveyor belt 41 to rotate in the reverse direction, and the rotation speed of the vehicle wheels is equal to the rotation speed of the conveyor belt 41, so as to simulate the vehicle driving normally without being limited by the driving distance.

[0047] It should be noted that, in order to ensure the synchronous start of the wheels and the conveyor belt 41 during the vehicle detection process and the stability during the vehicle detection process, a lift (not shown in the figure) is installed on the detection platform 1 in this embodiment. In this way, after the vehicle drives on the upper end of the conveyor belt 41, the vehicle can be lifted upward by the lift. Subsequently, the vehicle and the control of the rotation of the conveyor belt 41 are started simultaneously, and then the vehicle is lowered onto the conveyor belt 41, so as to ensure the stability of the vehicle. After the detection is completed, the conveyor belt 41 can be turned off to drive the vehicle out of the detection platform 1.

[0048] Continue to refer to Figure 4 As shown, in order to facilitate the synchronous rotation of the conveyor belt 41 with the vehicle wheels, in this embodiment, the two support shafts 44 on the same axis are connected after passing through the support frame 42. The driving assembly 46 includes an installation groove opened inside the detection platform 1. A driving motor 461 is arranged inside the installation groove. The axis of the output shaft of the driving motor 461 is parallel to the support shaft 44, and the driving motor 461 is connected to any one of the support shafts 44 through a belt drive. A belt 462 is jointly sleeved between the two support shafts 44 in the relative two directions of the length of the detection platform 1.

[0049] In the specific implementation process, after the vehicle drives to the upper end of the detection platform 1 and is lifted, the drive motor 461 is started. The drive motor 461 drives the support shaft 44 to rotate clockwise. Through the arrangement of the belt 462, the support shafts 44 on both sides in the length direction of the multiple detection platforms 1 rotate synchronously, thereby controlling the synchronous rotation of the multiple conveyor belts 41 with equal rotation speeds. Subsequently, the vehicle is started, and then the vehicle is lowered and the vehicle wheels are controlled to abut against the conveyor belt 41, so that the vehicle travels on the rotating conveyor belt 41, which can ensure the normal driving of the vehicle without displacement. At the same time, through the cooperation between the conveyor belt 41 and the vehicle wheels, roads with different flatness levels encountered during the normal driving of the vehicle can be simulated, so as to improve the detection effect on the vehicle suspension system.

[0050] It should be further noted that the above-mentioned lift can limit the vehicle to prevent the vehicle from moving along the length direction of the detection platform 1 and driving out of the detection platform 1.

[0051] Continue to refer to Figure 4 As shown, in order to facilitate enhancing the detection effect on the vehicle, in this embodiment, the conveyor belt 41 is an elastic structure for elastic deformation, and a plurality of strip-shaped grooves 411 for simulating the vehicle driving on a bumpy road section are uniformly formed on the outer side wall of the conveyor belt 41. When the vehicle wheels travel on the upper end of the conveyor belt 41, the uneven road surface can be simulated through the strip-shaped grooves 411. At this time, when detecting the vehicle suspension system, the vehicle driving on a bumpy road section can be simulated, so as to facilitate detecting the shock absorption effect of the suspension system.

[0052] Refer to Figure 5 、 Figure 6 and Figure 7 As shown, in order to facilitate detecting the shock absorption effect of the suspension system when the vehicle drives on a potholed road section, in this embodiment, positioning plates 421 are arranged on the opposite sides of the two support frames 42 in the same receiving groove 3. A hydraulic cylinder 422 is installed at the center of the bottom of the positioning plate 421. After the telescopic end of the hydraulic cylinder 422 extends to the upper end of the positioning plate 421, a jacking block 423 is provided. The jacking block 423 is in sliding contact with the inner top wall of the conveyor belt 41. A through hole for passing through the jacking block 423 is formed on the top support plate 45. In the initial state, the top of the jacking block 423 and the top support plate 45 are flush and jointly support the top of the conveyor belt 41 upward.

[0053] In the specific implementation process, the hydraulic cylinder 422 is started to drive the jacking block 423 to move up or down. When the jacking block 423 moves upward, an upward jacking force can be applied to the vehicle wheels to simulate the vehicle driving on a road section with protrusions. On the contrary, when the jacking block 423 moves downward, the conveyor belt 41 is depressed downward into the through hole under the gravity of the vehicle, and at this time, the vehicle driving on a road section with a pit can be simulated.

[0054] By controlling the up and down movement of the jacking blocks 423 at different positions, it is possible to simulate the situation where the vehicle is driving on a road section with bumps or a potholed road surface with unevenness, thereby realizing the conversion of road surface flatness, so as to respectively detect the shock absorption effect of the suspension system at different wheels of the vehicle, and then comprehensively detect the suspension system.

[0055] Refer to Figure 8 and Figure 9 As shown, in order to further convert the road surface flatness for detecting the suspension system, it is necessary to correspondingly control the flatness of the outer wall of the conveyor belt 41. Based on this, two push plates 31 that are symmetrically arranged along the conveyor belt 41 and sleeved outside the horizontal plate 43 are provided inside the accommodating groove 3. A plurality of filling strips 32 corresponding to the positions of the strip-shaped grooves 411 are provided on one side of the push plate 31 close to the conveyor belt 41.

[0056] Furthermore, in this embodiment, a linkage belt 33 sleeved on the outer walls of a plurality of support shafts 44 is installed on one side of the push plate 31 close to the conveyor belt 41. Through the linkage belt 33, the filling strips 32 can be driven to rotate synchronously with the conveyor belt 41. The filling strips 32 are installed on the side of the linkage belt 33 away from the push plate 31, and the side of the filling strip 32 away from the linkage belt 33 is slidably butted in the strip-shaped groove 411. In the initial state, the distance between the push plate 31 and the conveyor belt 41 is the largest. At this time, the filling strips 32 are located on both sides of the strip-shaped groove 411 in the length direction and will not block the vehicle wheels.

[0057] Even further, in this embodiment, the conveyor belt 41 is composed of an execution belt 412 and two auxiliary belts 413. Among them, the two auxiliary belts 413 are symmetrically arranged along the execution belt 412. The execution belt 412 and the auxiliary belts 413 rotate synchronously, and the filling strips 32 are slidably butted in the strip-shaped grooves 411 on the outer walls of the auxiliary belts 413. The top support plate 45 and the jacking blocks 423 are abutted against the inner top wall of the execution belt 412; the execution belt 412 and the auxiliary belts 413 rotate synchronously, and the auxiliary belts 413 will not affect the protrusions and depressions of the execution belt 412.

[0058] In the specific implementation process, control the push plate 31 to move towards the side close to the conveyor belt 41. The push plate 31 drives the filling strips 32 to move synchronously, so that the filling strips 32 fill the strip-shaped grooves 411 on the outer wall of the execution belt 412, so that the outer wall of the execution belt 412 is a plane as a whole, and further conversion of the flatness of the outer wall of the conveyor belt 41 can be realized. At this time, it is possible to simulate the vehicle driving on a flat road section to facilitate the detection of the stability of the vehicle suspension system. Embodiment

[0059] Refer to Figure 9As shown, on the basis of the first embodiment, in order to facilitate the automatic filling of the filling strip 32 into the strip groove 411 on the outer wall of the execution belt 412, based on this, a control assembly 34 is further provided in this embodiment. Specifically, the control assembly 34 includes force-receiving plates 341 installed on both side walls in the length direction of the push plate 31. On the opposite sides of the two opposite force-receiving plates 341, racks 342 are respectively arranged on the upper and lower sides. A plurality of transmission groups corresponding to the positions of the accommodation grooves 3 are arranged inside the detection platform 1. Each transmission group includes two fixed rotating shafts symmetrically arranged along the accommodation groove 3. A gear 343 that is located between the two racks 342 and meshes with them is sleeved on the outer wall of the fixed rotating shaft.

[0060] Furthermore, in this embodiment, the two fixed rotating shafts on the same side of the accommodation groove 3 are connected by a belt drive. A plurality of positioning motors 344 symmetrically arranged along the accommodation groove 3 are also installed inside the detection platform 1. The positioning motor 344 is connected to any one of the fixed shafts on the same side of the accommodation groove 3.

[0061] In the specific implementation process, when the positioning motor 344 is started, the positioning motor 344 drives the fixed rotating shaft and the gear 343 connected to its output shaft to rotate. The fixed rotating shaft drives another fixed rotating shaft and the gear 343 to rotate synchronously through the belt drive connection. Through the cooperation between the gear 343 and the rack 342, the force-receiving plate 341 can be driven to move relatively or away from each other. The force-receiving plate 341 drives the push plate 31 to move synchronously, so that the push plate 31 can automatically move towards the side close to the conveyor belt 41. Furthermore, the push plate 31 drives the filling strip 32 to automatically fill the strip groove 411, thereby realizing the automatic conversion of the flatness of the conveyor belt 41.

[0062] Refer to Figure 1 As shown, when using this vehicle maintenance and detection device to perform vehicle maintenance and detection, the following steps are included:

[0063] S1. Vehicle movement: First, drive the vehicle to the upper end of the detection platform 1 so that the four wheels of the vehicle are respectively located on the upper ends of the plurality of conveyor belts 41.

[0064] S2. Vehicle start: The tester starts the vehicle so that the wheels of the vehicle rotate on the upper end of the conveyor belt 41. At this time, the plurality of top support plates 45 can provide a supporting force for the conveyor belt 41. Then, the vehicle is lifted upward and the tester starts the vehicle. At the same time, the drive motor 461 is started, and the drive motor 461 drives the support shaft 44 to rotate clockwise, thereby controlling the plurality of conveyor belts 41 to rotate synchronously.

[0065] Subsequently, the vehicle is lowered and the vehicle wheels are controlled to abut against the conveyor belt 41, so that the vehicle travels on the rotating conveyor belt 41, thereby ensuring the normal driving of the vehicle without being restricted by the driving distance.

[0066] S3. Detection of the vehicle suspension system: The strip grooves 411 on the outer wall of the conveyor belt 41 can simulate an uneven road surface, and can simulate the vehicle driving on a bumpy road section, so as to facilitate the detection of the shock absorption effect of the suspension system.

[0067] In addition, starting the hydraulic cylinder 422, the hydraulic cylinder 422 drives the jacking block 423 to move up or down, which can simulate the vehicle driving on a road section with protrusions or a potholed road section with uneven road surface, so as to realize the conversion of road surface flatness; when the jacking block 423 moves upward, it can cause an upward jacking force on the vehicle wheels to simulate the vehicle driving on a road section with protrusions; on the contrary, when the jacking block 423 moves downward, the conveyor belt 41 is depressed into the through hole under the gravity of the vehicle, and at this time, it can simulate the vehicle driving on a road surface with pits; thus, the shock absorption effects of the suspension systems at different vehicle wheels can be detected respectively, and then the suspension system can be comprehensively detected.

[0068] Further, start the positioning motor 344. The output shaft of the positioning motor 344 drives the gear 343 to rotate through the fixed rotating shaft. The gear 343 cooperates with the rack 342 to drive the force receiving plate 341 and the push plate 31 to move relatively as a whole, so that the push plate 31 drives the filling strip 32 to fill the strip grooves 411 on the outer wall of the execution belt 412, so that the outer wall of the execution belt 412 is a plane as a whole, and further the flatness conversion of the outer wall of the conveyor belt 41 can be realized. At this time, it can simulate the vehicle driving on a flat road section to facilitate the detection of the stability of the vehicle suspension system.

[0069] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.

[0070] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
