Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of automobile inspection and calibration, and specifically to a column device and a calibration device. Background Art

[0002] Advanced Driving Assistance System (ADAS) can prevent or reduce traffic accidents. It uses sensors installed on the car (such as millimeter wave radar, laser radar, camera, ultrasonic radar, etc.) to sense the surroundings and collect environmental data during the driving process of the car, complete the identification, detection and tracking of static and dynamic objects, and calculate and analyze in combination with map data, so as to pre-judge potential dangers and improve safety. In order to ensure the normal operation of ADAS, the ADAS system must be recalibrated after the front windshield is replaced, the rear axle is adjusted, the four-wheel alignment is adjusted, the front of the vehicle is damaged or disassembled, etc. During calibration, the calibration instruments such as the ACC millimeter wave radar calibrator and the LDW camera calibration pattern plate need to be placed at the specified relative position and height, and ensure that they are centered relative to the vehicle. When calibrating the various parts of different ADAS systems, the calibration instruments need to work normally at different heights, and the lifting and lowering of the calibration instruments to different heights is achieved by lifting and lowering the column device on the calibration equipment.

[0003] The column device of the existing calibration equipment is directly driven by the lifting of the drive component to drive the lifting of the calibration instrument. The stroke height of the calibration instrument is equal to the stroke height of the drive component.

[0040] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0041] The column device of the existing calibration equipment includes a column, a drive assembly and a lifting platform. The calibration instrument is fixed on the lifting platform and rises and falls with the lifting platform. The drive assembly is set on the column. When the drive assembly is working, the lifting platform is fixedly connected to the output end of the drive assembly, so that the lifting and lowering of the output end of the drive assembly can drive the lifting platform to rise and fall together. The calibration instrument that is lifted and lowered by the lifting platform can only rise to the lifting height of the drive assembly. However, the lifting distance of the column device is limited, which makes the lifting range of the calibration instrument small and cannot meet the axial lifting requirements of the calibration instrument. As a result, when calibrating, the vehicle needs to be moved to cooperate with the existing calibration instrument to complete the calibration.

[0042] Based on this, the inventor of the present application discovered that a hanging assembly can be set on the lifting drive component in the column device, and the lifting platform in the column device can be hung on the hanging assembly through a flexible transmission member, and one end of the flexible transmission member is fixed to the column as a base, and the other end is connected to the lifting platform, so that the hanging assembly forms a movable pulley. By utilizing the motion characteristics of the movable pulley, the lifting platform can be lifted and lowered with a stroke twice that of the lifting drive component, thereby increasing the lifting stroke range of the lifting platform. At the same time, considering that the lifting platform will shake during the lifting and moving process after being hung on the flexible transmission member, the present application also connects the lifting platform to the lifting drive component in a lifting and sliding manner, so as to limit the movement of the lifting platform except the lifting direction through the sliding cooperation between the lifting drive component and the lifting platform, thereby ensuring the stability and reliability of the operation of the lifting platform.

[0043] When the column device is applied to the calibration equipment of the car, a crossbeam can be installed on the lifting platform, and the calibration instrument is installed on the crossbeam. During the calibration operation, if the actual position of the calibration instrument deviates from the preset position, it will affect the calibration of the ADAS system by the calibration instrument. Therefore, if the lifting platform is directly hung on the flexible transmission part, the lifting platform will shake during the lifting process, which will directly affect the angle and horizontal height of the calibration instrument on the crossbeam, causing the actual position reached by the calibration instrument to deviate from the preset position. In this regard, the lifting platform is limited by slidingly connecting the lifting platform to the lifting drive component, which can improve the stability of the crossbeam on the lifting platform and the calibration instrument on the crossbeam during the lifting process, thereby ensuring that the calibration instrument can better reach the preset position.

[0044] The column device provided in the present application includes, but is not limited to, calibration equipment for automobiles and other mechanical equipment that require lifting and lowering movements. The following description will be given using the calibration equipment for automobiles as an example.

[0045] Specifically, see Figure 1 and Figure 2 , Figure 1 The overall structure of the column device provided in the embodiment of the present application is shown. Figure 2 The column device 100 is shown in the figure. As shown in the figure, the column device 100 includes: a column 110, a driving assembly 120, a guide rail assembly 130, a hanging assembly 140, a flexible transmission member 150 and a lifting platform 160; wherein the driving assembly 120 is arranged on the column 110; the guide rail assembly 130 is fixedly connected to the output end of the driving assembly 120, and can be lifted and slidably connected to the column 110, and the guide rail assembly 130 is used to lift and slide relative to the column 110 under the drive of the driving assembly 120; the hanging assembly 140 is arranged on the guide rail assembly 130, and moves with the guide rail assembly 140. The assembly 130 is raised and lowered; the flexible transmission member 150 is suspended on the hanging assembly 140, and one end is fixed relative to the column 110, and the other end is fixedly connected to the lifting platform 160; the lifting platform 160 is connected to the guide rail assembly 130 in a lifting and sliding manner, and the lifting platform 160 is used to rise along the guide rail assembly 130 driven by the flexible transmission member 150 when the guide rail assembly 130 rises relative to the column 110, and the lifting platform 160 is also used to descend along the guide rail assembly 130 under the action of gravity when the guide rail assembly 130 descends relative to the column 110.

[0046] Specifically, the drive assembly 120 can be as follows Figure 2 The screw module is shown in the figure, and of course in some other embodiments, hydraulic cylinders, pneumatic cylinders, belt pulleys, sprocket chains, size racks and other mechanisms can also be used to achieve the lifting and lowering drive of the guide rail assembly 130. The output end of the drive assembly 120 refers to the component in the drive assembly 120 used to finally output the lifting driving force. For example, when the drive assembly 120 is a screw module, its output end is a nut that moves relative to the screw rod. When the drive assembly 120 is a hydraulic cylinder or a pneumatic cylinder, its output end is a piston rod. When the drive assembly 120 is a belt pulley, a sprocket chain or a gear rack, its output end is a belt, a chain or a rack.

[0047] It should be pointed out that the embodiment of the present application does not specifically limit the driving assembly 120, the hanging assembly 140 and the flexible transmission member 150, and they can be selected according to actual use requirements. When the driving assembly 120 is a motor, a sprocket and a chain, the motor drives the sprocket to rotate, and the sprocket drives the chain to rotate, so that the chain rises and falls along the axial direction of the column 110, thereby driving the guide rail assembly 130 fixed on the chain to rise and fall; when the driving assembly 120 is a motor, a gear and a rack, the motor drives the gear to rotate, and the gear drives the rack to rotate, so that the rack rises and falls along the axial direction of the column 110, thereby driving the guide rail assembly 130 fixed on the rack to rise and fall; when the driving assembly 120 is a pneumatic cylinder, the lifting of the piston of the pneumatic cylinder can drive the guide rail assembly 130 fixed on the piston to rise and fall. The hanging assembly 140 and the flexible transmission member 150 can be a sprocket and chain, a pulley and a synchronous belt, or a pulley and a steel cable.

[0048] exist Figure 2In the specific embodiment shown, a first linear guide 1101 is provided on the column 110, and the guide assembly 130 is slidably connected to the first linear guide 1101, so as to realize the lifting and lowering movement of the guide assembly 130 relative to the column 110. A second linear guide 1301 is provided on the guide assembly 130, and the lifting platform 160 is slidably connected to the second linear guide 1301, so as to realize the lifting and lowering sliding of the lifting platform 160 on the guide assembly 130.

[0049] When the driving component 120 is working, the guide rail component 130 is fixedly connected to the output end of the driving component 120, so that the lifting and lowering of the output end of the driving component 120 can drive the guide rail component 130 to be lifted and lowered along the column 110; the hanging component 140 is arranged on the guide rail component 130, so that the lifting and lowering of the guide rail component 130 can drive the hanging component 140 to be lifted and lowered together; the flexible transmission member 150 is hung on the hanging component 140, and one end is relatively fixed to the column 110, and the other end is fixedly connected to the lifting platform 160, so that the lifting platform 160, the flexible transmission member 150 and the hanging component 140 cooperate to lift and lower, and the hanging component 140 is equivalent to a movable pulley. By utilizing the movement characteristics of the movable pulley, the lifting platform 160 can be lifted and lowered with twice the stroke of the hanging component 140, so that the lifting platform 160 can rise to a height that is twice the height that the guide rail component 130 can rise. Therefore, when the crossbeam and marking instrument are installed on the lifting platform 160, the calibration instrument driven by the lifting platform 160 can rise to a height that is twice the height of the guide rail assembly 130, thereby expanding the lifting and lowering range of the calibration instrument and meeting the lifting and lowering range requirements of the calibration instrument during calibration, thus avoiding the need to move the vehicle to complete the calibration.

[0050] The column device of the existing calibration equipment includes a column, a driving component and a lifting platform. When the driving component is working, the lifting platform is fixedly connected to the output end of the driving component, so that the lifting of the output end of the driving component can drive the lifting platform to rise and fall together, and the calibration instrument that is lifted and lowered by the lifting platform can only rise to the lifting height of the driving component. According to the motion characteristics of the movable pulley, when the lifting height of the lifting platform 160 is the same, the work required by the driving component 120 in the embodiment of the present application is only half of the work done by the driving component of the existing calibration equipment, that is, half of the output of the driving component 120 can be saved; and, when the lifting height of the lifting platform 160 is the same, the lifting time required by the lifting platform 160 in the embodiment of the present application is only half of the lifting time required by the lifting platform of the existing calibration equipment, thereby improving the calibration efficiency of the calibration instrument.

[0051] Furthermore, the lifting platform 160 is arranged on the guide rail assembly 130. When the guide rail assembly 130 rises, the lifting platform 160 rises along the guide rail assembly 130 under the pull of the flexible transmission member 150. When the guide rail assembly 130 descends, the lifting platform 160 descends along the guide rail assembly 130 under the action of gravity, thereby reducing the shaking of the lifting platform 160 during the lifting process, improving the stability of the calibration instrument and the reliability of the column device 100, and avoiding the shaking of the lifting platform 160 due to the shaking of the flexible transmission member 150 during the transmission process, thereby preventing the actual position of the calibration instrument from deviating greatly from the preset position to be lifted after the calibration instrument is installed on the lifting platform 160.

[0052] The column device 100 provided in the embodiment of the present application is lifted and lowered by the cooperation between the lifting platform 160, the flexible transmission member 150 and the hanging assembly 140, wherein the hanging assembly 140 is equivalent to a movable pulley. By utilizing the motion characteristics of the movable pulley, the lifting platform 160 can be lifted and lowered with a stroke twice that of the hanging assembly 140, that is, it can be lifted and lowered with a stroke twice that of the guide rail assembly 130, thereby expanding the lifting and lowering stroke range of the lifting platform 160, meeting the requirements for the lifting and lowering stroke range when the calibration instrument is calibrated when applied to calibration equipment, and avoiding the situation where the calibration needs to be completed by moving the vehicle. In addition, the lifting platform 160 can be lifted and lowered and slidably connected to the guide rail assembly 130. By limiting the lifting platform 160 by the guide rail assembly 130, the shaking of the lifting platform 160 during the lifting process can be reduced, thereby improving the stability and reliability of the overall operation of the column device 100.

[0053] Regarding the specific structure of the driving assembly 120, this application proposes an implementation method. Figure 3 , the figure shows the internal structure of the column device. As shown in the figure, the driving assembly 120 includes a driving member 121, a screw module 122 and a sleeve 123; the driving member 121 is fixed to the column 110; the driving member 121 is connected to the bottom end of the screw in the screw module 122, and is used to drive the screw to rotate, so that the nut sleeved on the screw in the screw module 122 can be lifted and slid, and the sleeve 123 is sleeved and fixed on the nut, and is used to slide with the nut; the guide rail assembly 130 is fixedly connected to the side of the sleeve 123, and is used to slide with the sleeve 123 under the drive of the driving member 121.

[0054] When the driving member 121 is working, the driving member 121 drives the screw to rotate by connecting with the bottom end of the screw in the screw module 122. After the screw rotates, the nut sleeved on the screw in the screw module 122 will move along the axial direction of the screw and perform linear motion. That is, the driving member 121 drives the screw to rotate to make the nut perform axial lifting and sliding, and then the nut drives the sleeve 123 to perform axial lifting and sliding movement. The guide rail assembly 130 is fixedly connected to the side of the sleeve 123 and slides and rises and falls along the column 110 as the sleeve 123 moves up and down.

[0055] In the lead screw module 122, its nut can move from the top of the screw to the bottom of the screw, so under a limited length, the lead screw module 122 has a large moving stroke. Based on this, in this embodiment, under the premise of using the lead screw module 122, by sleeve 123 on the nut of the lead screw module 122, and by the sleeve 123 and the guide rail assembly 130 are fixedly connected, so that the sleeve 123 and the guide rail assembly 130 can be fully and reliably fixed. Further, by fixing the guide rail assembly 130 to the side of the sleeve 123, the guide rail assembly 130 can be extended to the bottom position of the sleeve 123, thereby ensuring that the lifting platform 160 that can be lifted and slidably connected to the guide rail assembly 130 can slide from the side of the sleeve 123 to the bottom position of the sleeve 123, thereby ensuring that the lifting platform 160 has a large lifting and moving stroke.

[0056] For the calibration equipment of the automobile, the calibration instrument needs to be calibrated at multiple levels. When the lifting platform 160 needs to be as low as possible, the nut of the screw module 122 can be rotated to a position close to the bottom end of the screw to reduce the height of the lifting platform 160 as much as possible, so that the height of the lifting platform 160 from the ground is relatively small to reach the height required by the calibration instrument, thereby avoiding the need to move the vehicle in order to complete the calibration of the calibration instrument. The guide rail assembly 130 is fixedly connected to the side of the sleeve 123 to ensure that the lifting platform 160 is lowered to the lowest end of the screw, thereby meeting the height requirement required for calibration.

[0057] For further information, see Figure 4 , the figure shows the structure of the column device from the bottom perspective. As shown in the figure, in some embodiments, a position on the lifting platform 160 opposite to the sleeve 123 is provided with an avoidance groove 161, which is used to avoid the sleeve 123 so that the lifting platform 160 can be lifted and slid to the side of the sleeve 123.

[0058] By providing the avoidance groove 161 on the lifting platform 160, it is possible to prevent the lifting platform 160 from rubbing against or interfering with the sleeve 123 during the lifting process, thereby ensuring the stability of the operation. When the lifting platform 160 needs to be as low as possible, the avoidance groove 161 on the lifting platform 160 allows the lifting platform 160 to slide to the side of the sleeve 123 to lower the height of the lifting platform 160, thereby reducing the height of the lifting platform 160 from the ground, thereby increasing the lifting stroke of the lifting platform 160 and reaching the height required when the calibration instrument is calibrated.

[0059] In order to improve the stability of the lifting platform 160 during the lifting process, in an optional manner, please refer to Figure 3 As shown in the figure, the guide rail assembly 130 includes a first guide rail 131 and a second guide rail 132; the first guide rail 131 and the second guide rail 132 are fixed on the two opposite sides of the sleeve 123, and both can be lifted and slidably connected to the column 110, and the first guide rail 131 and the second guide rail 132 are used to be lifted and moved synchronously with the sleeve 123 under the drive of the driving member 121; the lifting platform 160 is respectively connected to the first guide rail 131 and the second guide rail 132 for lifting and sliding.

[0060] exist Figure 3 In the specific embodiment shown, the column 110 includes two linear guide rails, and the first guide rail 131 and the second guide rail 132 are respectively connected to the two linear guide rails in a liftable and slidable manner.

[0061] Considering that if the guide rail assembly 130 uses one guide rail and is fixedly connected to the side of the sleeve 123, the stress distribution on the guide rail assembly 130 is uneven, so that it is easy to slip, fall, etc. during the lifting process. Based on this, in this embodiment, two guide rails (the first guide rail 131 and the second guide rail 132) are respectively fixed on the two opposite sides of the sleeve 123, and the lifting platform 160 is slidably connected to the two guide rails, so that the guide rail assembly 130 is evenly stressed, ensuring the stability and reliability of the guide rail assembly 130 and the lifting platform 160 during lifting and lowering operation.

[0062] Furthermore, in a preferred embodiment, the first guide rail 131 and the second guide rail 132 are symmetrically arranged on both sides of the lifting platform 160 to further improve the stability of the lifting platform 160 during the lifting process.

[0063] Please continue reading Figure 3For the embodiments using the first guide rail 131 and the second guide rail 132, further, in some embodiments, the hanging assembly 140 includes a first hanging member 141 and a second hanging member 142; the first hanging member 141 is arranged at the top of the first guide rail 131 and rises and falls with the first guide rail 131, and the second hanging member 142 is arranged at the top of the second guide rail 132 and rises and falls with the second guide rail 132; the flexible transmission member 150 includes a first sub-flexible transmission member 151 and a second sub-flexible transmission member 152, the first sub-flexible transmission member 151 is hung on the first hanging member 141, and the second sub-flexible transmission member 152 is hung on the first hanging member 141. The sub-flexible transmission member 152 is suspended on the second hanging member 142, one end of the first sub-flexible transmission member 151 and one end of the second sub-flexible transmission member 152 are relatively fixed to the column 110, and the other end of the first sub-flexible transmission member 151 and the other end of the second sub-flexible transmission member 152 are fixedly connected to the lifting platform 160; the lifting platform 160 is used to lift and slide along the first guide rail 131 and the second guide rail 132 driven by the first sub-flexible transmission member 151 and the second sub-flexible transmission member 152 when the first guide rail 131 and the second guide rail 132 are lifted and slid relative to the column 110.

[0064] By setting the first hanging member 141 at the top of the first guide rail 131, setting the second hanging member 142 at the top of the second guide rail 132, and hanging the first sub-flexible transmission member 151 on the first hanging member 141, hanging the second sub-flexible transmission member 152 on the second hanging member 142, and the first sub-flexible transmission member 151 and the second sub-flexible transmission member 152 are fixedly connected to the lifting platform 160, the stability of the lifting platform 160 can be fully guaranteed and the carrying capacity of the lifting platform 160 can be improved.

[0065] See also Figure 5 , the figure shows Figure 2 Enlarged structure at A. As shown in the figure, in some embodiments, the column device 100 further includes a limiter 170, the limiter 170 is fixed to the top of the guide rail assembly 130, and the hanging assembly 140 is arranged at the top of the limiter 170 away from the guide rail assembly 130; a notch 171 is arranged on the limiter 170, and the flexible transmission member 150 passes through the notch 171, and the inner wall of the notch 171 is used to limit the swing of the flexible transmission member 150.

[0066] Specifically, in the process of driving the lifting platform 160 to move up and down, the flexible transmission member 150 will inevitably vibrate, causing the flexible transmission member 150 to swing. In order to prevent the flexible transmission member 150 from swinging too much and causing decoupling, breakage, etc., a notch 171 is opened on the limit member 170 in this embodiment. When the flexible transmission member 150 swings greatly, the inner wall of the notch 171 abuts against the flexible transmission member 150 to limit the flexible transmission member 150, ensuring that the flexible transmission member 150 does not shake significantly, thereby ensuring the stability and reliability of the transmission between the flexible transmission member 150 and the lifting platform 160.

[0067] Please combine Figure 1 and Figure 2 In an optional manner, the driving assembly 120 is disposed inside the column 110 , and the guide rail assembly 130 is connected to the inner wall of the column 110 in a liftable and slidable manner.

[0068] The driving assembly 120 is disposed inside the column 110, and the guide rail assembly 130 can be raised and lowered and slidably connected to the inner wall of the column 110, so that the column 110 can not only maintain the stability of the guide rail assembly 130 when sliding, but also prevent the driving assembly 120 from being exposed to the outside and being caught in debris, thereby interfering with the normal operation of the driving assembly 120.

[0069] According to another aspect of the embodiments of the present application, a calibration device is also provided, which includes the column device 100 as in any of the above embodiments.

[0070] Furthermore, in some embodiments, the calibration device also includes a crossbeam and a calibration instrument. The crossbeam is fixedly connected to the lifting platform 160. The lifting platform 160 is used to drive the crossbeam to rise and fall and slide relative to the column 110. The calibration instrument is arranged on the crossbeam, and the calibration instrument is used to calibrate the car.

[0071] When the calibration equipment is used to calibrate the car, the calibration instrument on the crossbeam can be raised and lowered by raising and lowering the lifting platform 160 on the calibration equipment, thereby adjusting the height of the calibration instrument to complete various calibration operations.
