Description

[0001] Cross Reference to Related Applications

[0002] The present application claims priority to the Chinese patent application No. 2021107689937, filed on July 7, 2021, and entitled "Vehicle measurement device and calibration method", the entire content of which is incorporated herein by reference. TECHNICAL FIELD

[0003] Embodiments of the present application relate to the field of automobile calibration, in particular to a lifting system and a vehicle measurement device. BACKGROUND

[0004] When a four-wheel alignment instrument measures the wheel state of a vehicle, the whole vehicle needs to be lifted, and the cross beam needs to be as high as 2100mm, which occupies a lot of longitudinal space and is inconvenient to move. Therefore, the four-wheel alignment instrument is usually fixed. However, when a vehicle calibration device calibrates the driving assistance system of a vehicle, the cross beam needs to be movable, and the height of the cross beam from the ground needs to be relatively low, generally 300-1100mm. The four-wheel alignment and the vehicle calibration device have different height intervals and different movable properties. Currently, there are two design directions for the four-wheel alignment instrument and the vehicle calibration device: one is two independent devices, which doubles the cost of purchasing the devices, and the vehicle needs to be moved to two workstations for detection, which is extremely low in maintenance efficiency; the other is a movable device that integrates the four-wheel alignment instrument and the vehicle calibration device. In order to ensure that the movable device can pass through the door of the measurement site, the height of the column cannot exceed 2000mm, which is converted into a lower cross beam. After sacrificing the height of the column, the lifting height of the whole vehicle is reduced when the four-wheel alignment instrument is used, and the maintenance personnel need to bend down to adjust the four wheels, which is completely inconsistent with the ergonomics.

[0005] Therefore, it is necessary to provide a lifting system to meet the height requirements of the four-wheel alignment instrument and the vehicle calibration device, and to improve the measurement efficiency. SUMMARY

[0049] Please see Figures 1-2 This is a schematic diagram of an application scenario of a lifting system 100 provided in one embodiment of the present invention. The lifting system 100 is applied to a vehicle measuring device 1000, which integrates a four-wheel alignment instrument and a vehicle calibration device. The four-wheel alignment instrument is used to measure the wheel state of the vehicle, and the vehicle calibration device is used to calibrate the vehicle's driving assistance system.

[0050] Since the required crossbeam height for measuring vehicle wheel conditions and calibrating the vehicle's driver assistance system differs, this application provides a lifting system 100 to switch the crossbeam to different heights to meet the height requirements of the four-wheel alignment machine and vehicle calibration equipment. Furthermore, having the crossbeam at different heights allows the lifting system 100 to be applied to more scenarios; for example, the same vehicle measuring device 1000 can be used to calibrate vehicles of different models.

[0051] Please refer to the following: Figures 3-6 The lifting system 100 includes a fixed column 10, a movable column assembly 20, and a drive assembly 40. The movable column assembly 20 is sleeved inside the fixed column 10 and can be raised and lowered relative to the fixed column 10. The drive assembly 40 is installed on the fixed column 10 and connected to the movable column assembly 20. The drive assembly 40 is used to drive the movable column assembly 20 to rise and lower relative to the fixed column 10.

[0052] In some embodiments, the lifting system 100 may further include a lifting plate 30, which is installed on the movable column assembly 20. The lifting plate 30 is used to install the crossbeam assembly of the vehicle measuring equipment, so that when the movable column assembly 20 is raised or lowered relative to the fixed column 10, the lifting plate 30 and the crossbeam assembly are raised or lowered together.

[0053] It should be noted that the crossbeam assembly is equipped with a calibration element and a wheel image acquisition component. The calibration element is used to calibrate the vehicle's driver assistance system, and the wheel image acquisition component is used to acquire images of the vehicle's wheels.

[0054] In some embodiments, the fixed column 10 includes a column housing 11 and a fixed support 12, the fixed support 12 being installed on the column housing 11 and used to connect to the drive assembly 40.

[0055] The column shell 11 comprises a base 111, a first column shell 112 and a second column shell 113. The first column shell 112 is mounted on the base 111 and forms a receiving cavity (not labeled), and the second column shell 113 is detachably connected to the first column shell 112 to cover the receiving cavity. The driving assembly 40 is received in the receiving cavity, and the first column shell 112 and the second column shell 113 have a first gap 101 along the lifting direction of the movable column assembly 20. The lifting plate 30 can extend out of the first gap 101 and move along the first gap 101. The fixed support 12 is detachably mounted on the base 111 and received in the receiving cavity.

[0056] Please refer to Figures 7-8 The movable column assembly 20 comprises a first housing 21, a second housing 22, a cover plate 23 and a top cover 24. The first housing 21 and the second housing 22 are both fixed to the cover plate 23, and the first housing 21 and the second housing 22 have a second gap 201 along the lifting direction of the movable column assembly 20. The lifting plate 30 is mounted on the second gap 201, and the second gap 201 is in communication with the first gap 101. The top cover 24 covers the cover plate 23.

[0057] Please refer to Figure 9 In some embodiments, the driving assembly 40 is an electric push rod. The driving assembly 40 comprises a conversion box 41, a main body 42, a driving motor 43 and a push rod assembly. The conversion box 41 is mounted on the first column 10, specifically, the conversion box 41 is mounted on the fixed support 12. The main body 42 and the driving motor 43 are both fixed to the conversion box 41. The push rod assembly comprises a lead screw 44 and a push rod 45. The output shaft of the driving motor 43 is coaxially fixed with the lead screw 44. The lead screw 44 is received in the main body 42. One end of the push rod 45 is threadedly connected with the lead screw 44, and the other end of the push rod 45 is fixedly connected with the movable column assembly 20. The push rod 45 is arranged along the length direction of the fixed column 10. When the driving motor 43 rotates, the push rod 45 can drive the movable column assembly 20 to lift along the length direction of the fixed column 10 under the driving of the driving motor 43.

[0058] In some embodiments, the driving assembly 40 further comprises a gear assembly. The gear assembly is received in the conversion box 41. For example, the gear assembly comprises a driving gear and a plurality of driven gears. The output shaft of the driving motor 43 is in transmission connection with the driving gear. The driving gear and the plurality of driven gears are in meshing with each other. The lead screw 44 is coaxially fixed with the last driven gear.

[0059] It is understood that the gear assembly can be replaced with other transmission components, as long as they can participate in the transmission and cause the lead screw 44 to rotate when the drive motor 43 rotates.

[0060] In addition, the push rod in the above-mentioned push rod assembly can be replaced with a nut seat. For example, the nut seat is fixed to the movable column assembly 20, and the nut seat is threadedly connected to the lead screw 44.

[0061] In some embodiments, please refer to Figure 10 To prevent excessive swaying of the push rod 45 during its movement, a limiting seat 13 is provided on the inner wall of the fixed column 10, and the push rod 45 passes through the limiting seat 13 and connects to the movable column assembly 20.

[0062] In some embodiments, the fixed support 12 and the limiting seat 13 are located at both ends of the column shell 11.

[0063] In some embodiments, to facilitate the connection between the push rod 45 and the movable column assembly 20, the top of the push rod 45 is provided with a connecting shaft, and the cover plate 23 is provided with a connecting seat. The connecting shaft is engaged with the connecting seat, thereby realizing the connection between the push rod and the movable column assembly.

[0064] It is understood that in other embodiments, the drive component may also be a linkage mechanism or a cam mechanism, etc., and all mechanisms that enable the movable column assembly 20 to rise and fall relative to the fixed column 20 are within the scope of protection of this application.

[0065] In some embodiments, please refer to Figure 11 Since both the drive assembly 40 and the movable column assembly 20 are installed inside the fixed column 10, in order to avoid interference between the drive assembly 40 and the movable column assembly 20, the movable column assembly 20 is provided with a clearance groove 221 on the side near the drive assembly 40. That is, the second housing 22 is provided with a clearance groove 221, which is used to accommodate the main body 42 and the push rod 45.

[0066] Please continue reading. Figure 10 In some embodiments, to make the lifting of the movable column assembly 20 more stable, the lifting system 100 includes a first guide assembly 50. The first guide assembly 50 includes a first guide rail 51 and a first slider 52. The first guide rail 51 is fixed to the inner wall of the fixed column 10. For example, the first guide rail 51 is fixed to the second housing 22 along the length of the fixed column 10. The first slider 52 is slidably disposed on the first guide rail 51. The movable column assembly 20 is fixed to the first slider 52.

[0067] It can be understood that the first guide component 50 is used to orient the movable column component 20 to rise or fall under the action of the drive component 40.

[0068] In some embodiments, there are two first guide rails 51 and four first sliders. Two first guide rails 51 are spaced apart on the inner wall of the fixed column, and two first sliders 52 are slidably mounted on one first guide rail 51.

[0069] It is understood that, due to the large size of the movable column assembly 20, in order to ensure that the movable column assembly 20 can be stably connected to the first slider 52, the first guide assembly 50 also includes a first sliding plate 53. The movable column assembly 20 is fixed to the first slider 52 by the first sliding plate 53, that is, the first sliding plate 53 is fixed to the four first sliders 52.

[0070] Please refer to the following: Figures 6-8 In some embodiments, to facilitate rapid switching between the four-wheel alignment system and the vehicle calibration equipment, the lifting system 100 further includes a traction component 60. The traction component 60 includes a traction member 61, which is mounted on the top of the movable column assembly 20. One end of the traction member 61 is connected to the lifting plate 30, and the other end is connected to the fixed column 10. This allows the lifting plate 30 and the movable column assembly 20 to form a linkage system, so that when the movable column assembly 20 rises and falls relative to the fixed column 10, the lifting plate 30 rises and falls in tandem with the movable column assembly 20. This results in the lifting height of the lifting plate 30 relative to the fixed column 10 being twice the lifting height of the movable column assembly 20 relative to the fixed column 10, thereby improving the switching efficiency between the four-wheel alignment system and the vehicle calibration equipment.

[0071] It should be noted that the cover plate 23 is provided with two through holes spaced apart. One end of the traction member 61 passes through one of the through holes and is connected to the lifting plate 30. The other end of the traction member 61 passes through the other through hole and is connected to the fixed column 10. This allows the lifting plate 30 to rise and fall relative to the moving column assembly 20 when the end of the traction member 61 connected to the lifting plate 30 is raised and lowered.

[0072] In some embodiments, to increase the stroke of the lifting plate 30, the end of the traction member 61 away from the lifting plate 30 is connected to the bottom of the fixed column 10.

[0073] It is understood that the bottom of the movable column assembly 20 is provided with an opening for the traction member 61 to pass through, so that the traction member 61 can be connected to the fixed column 10 through the opening, or the traction member 61 can be connected to the fixed column 10 through the second gap 201.

[0074] In some embodiments, the traction member 61 may be a rope, wire rope, or chain, etc.

[0075] This application uses the traction component 61 as an example for illustration.

[0076] Specifically, in some embodiments, the traction assembly 60 further includes a mounting base 62 and a rotating component 63. The mounting base 62 is fixed to the cover plate 23, and the rotating component 63 is rotatably mounted on the mounting base 62. Both the mounting base 62 and the rotating component 63 are disposed within the space enclosed by the cover plate 23 and the top cover 24 to maintain aesthetics. The traction component 61 is partially wrapped around the rotating component 63, and the rotating component 63 is used to reduce the friction between the traction component 61 and the mounting base 62. In this embodiment, the rotating component 63 is a sprocket, and the chain meshes with the sprocket. When the drive assembly 40 drives the movable column assembly 20 to rise and fall, the chain 61 drives the lifting plate 30 to rise and fall relative to the movable column assembly 20.

[0077] It is understood that the rotating component can also be other structures, as long as the traction component and the rotating component can cooperate with each other. For example, the traction component is a belt and the rotating component is a pulley.

[0078] In some embodiments, to improve the stability of the connection between the lifting plate 30 and the traction member 61, there are two chains, and the sprockets 63 correspond one-to-one with the chains 61. That is, there are two mounting seats 62, with the two mounting seats 62 spaced apart from the cover plate 23, and one sprocket 63 rotatably mounted on one mounting seat 62.

[0079] It should be understood that in some embodiments, the lifting plate 30 may be omitted. In this case, one end of the traction member 61 is directly connected to the crossbeam assembly, and the other end of the traction member 61 is directly installed on the fixed column 10. At this time, at least two traction members 61 need to be provided so that the crossbeam assembly can be kept horizontally balanced when the traction member 61 is connected to the crossbeam assembly.

[0080] In some embodiments, please refer to Figure 8To improve the stability of the lifting plate 30 relative to the movable column assembly 20 during lifting, the lifting system 100 also includes a second guide assembly 70. The second guide assembly 70 includes a second guide rail 71 and a second slider 72. The second guide rail 71 is disposed on the second housing 22 along the length direction of the movable column assembly 20. The second slider 72 is slidably connected to the second guide rail 71. The lifting plate is fixed to the second slider 72 so that the lifting plate 30 can slide along the second guide rail 71 under the drive of the second slider 72.

[0081] In some embodiments, the number of the second guide rails 71 is 2, the number of the second sliders is 4, two second guide rails 71 are spaced apart on the inner wall of the movable column assembly 20, and two second sliders 72 are slidably mounted on one of the second guide rails 71.

[0082] It is understood that, since the lifting plate 30 is used to install the crossbeam assembly, and the crossbeam assembly is relatively heavy, in order to ensure that the lifting plate 30 can be stably connected to the second slider 72, the second guide assembly 70 also includes a second sliding plate 73. The lifting plate 30 is fixed to the second slider 72 through the second sliding plate 73. That is, the lifting plate 30 is fixed to the second sliding plate 73, and the second sliding plate 73 is fixed to the four second sliders 72.

[0083] In some embodiments, the fixed column 10 is provided with a first fixing seat 14 (e.g., Figure 10 As shown in the figure, specifically, the first fixed seat 14 is disposed at one end of the first column shell 112 near the base 111, and the end of the traction member 61 away from the lifting plate 30 is fixed to the first fixed seat 14.

[0084] It can be understood that the first fixing seat 14 corresponds one-to-one with the traction member 61, that is, when the number of the traction member 61 is 2, the number of the first fixing seat 14 is also 2.

[0085] In some embodiments, please refer to Figure 12 To avoid installation errors between components in the lifting system 100 or excessive weight of the crossbeam assembly causing obstruction to the moving column assembly 20 during lifting (e.g., the moving column assembly 20 abutting against the fixed column 10), thus preventing the moving column assembly 20 from lifting normally, the lifting system 100 further includes an adjustment assembly 80. The adjustment assembly 80 is used to adjust the angle of the moving column assembly 20 relative to the fixed column 10. Specifically, the adjustment assembly 80 includes an adjustment seat 81 and a second fixed seat 82. The adjustment seat 81 (see...) Figure 5The first fixed seat 82 is located at the bottom of the conversion box 41, and the second fixed seat 82 is located at the bottom of the fixed column 10. Specifically, the second fixed seat 82 is fixed to the base 111, and the adjusting seat 81 is rotatably connected to the second fixed seat 82, so that the moving column assembly 20 can be driven by the driving assembly 40 to rise and fall relative to the fixed column 10 under the action of the adjusting assembly 80.

[0086] In some embodiments, please refer to Figure 11 The lifting system further includes a control module 90, which is located on the fixed column 10, for example, on the first housing 11. The control module 90 includes a main control board and a power supply assembly. The power supply assembly is electrically connected to both the main control board and the drive motor, and supplies power to both the main control board and the drive motor. The main control board controls the start / stop and direction of the drive motor.

[0087] In some embodiments, the first housing 11 is provided with a first button, a second button and a third button, which are electrically connected to the main control board. The first button is used to control the start / stop of the drive motor, the second button is used to control the drive motor to rotate forward, and the third button is used to control the drive motor to rotate in reverse.

[0088] It should be noted that when the drive motor 43 rotates forward, the movable column assembly 20 rises relative to the fixed column 10, and when the drive motor 43 rotates in reverse, the movable column assembly 20 falls relative to the fixed column 10.

[0089] Taking the lifting plate 30 at its lowest position (the height required by the vehicle calibration equipment) as an example, the height of the lifting plate 30 from the ground is 300mm, and the height of the lifting plate 30 at its highest position (the height required by the four-wheel alignment machine) is 2100mm, the lifting plate 30 needs to be raised and lowered by 1800mm to switch between the highest and lowest positions. By introducing a traction member 61, one end of the traction member 61 is connected to the lifting plate 30, and the other end is connected to the moving column assembly 20. This allows the drive motor 43 in the drive assembly 40 to drive the push rod 45 to be raised and lowered by 900mm, thus enabling the lifting plate 30 to switch between the lowest and highest positions. This reduces the need for half the output selection of the drive motor and improves the switching efficiency between the four-wheel alignment machine and the vehicle calibration equipment.

[0090] This application embodiment also provides a vehicle measuring device 100, such as... Figure 1The vehicle measuring device 1000 includes a lifting system 100, a base 200, and a crossbeam assembly 300. The lifting system 100 is mounted on the base 200, and the crossbeam assembly 300 is mounted on the lifting plate 30. The crossbeam assembly 300 is used to carry calibration elements, which are used to calibrate the vehicle's driving assistance system.

[0091] In some embodiments, the vehicle measuring device 1000 further includes two wheel image acquisition components 400, which are laterally spaced at both ends of the crossbeam assembly 300. The field of view of the two wheel image acquisition components 400 is respectively used to cover the areas where the wheels are located on both sides of the vehicle.
