In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0032] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists, A and B exist at the same time, and B exists. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0036] 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.

[0037] Advanced Driving Assistance System (ADAS) can prevent or reduce traffic accidents. Its principle is to use sensors installed on the car (such as millimeter wave radar, laser radar, camera, ultrasonic radar, etc.) to sense 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, after the removal and replacement of the front windshield, rear axle adjustment, four-wheel alignment adjustment, damage or disassembly of the front of the vehicle, etc., the ADAS must be re-diagnosed and calibrated using calibration equipment.

[0038] In the prior art, the front cover of the column is fastened to the side plate of the outer column by screws, and is used to cover the internal structure of the column and serve as an exterior decoration. Generally, since the driving mechanism inside the column needs to be connected to the external beam so as to drive the beam up and down through the driving mechanism, the cover needs to be split into at least two pieces, and the edges of each piece are fixed to the column by screws respectively. Combined with the large height dimensions of the column and the cover, a large number of screws are required to install and fix the front cover on the outer column. Generally, more than 10 screws are required for fixing. Not only does it take a long time to install or remove the front cover, but also, since the screws are exposed on the outer surface of the outer column, the appearance of the column is affected.

[0039] Based on this, the present application proposes a column for a calibration device. In the case where two front cover plates need to be installed and fixed to the columns separately, the front cover plate can be quickly installed by simply inserting the front cover plate into the corresponding slide groove of the column body. The front cover plate can be quickly removed by pulling it out of the card slot. The operation is convenient and fast, which reduces the assembly and disassembly time of the staff. At the same time, since the front cover plate and the side panel of the column body are fixed by plugging, the fastening screws are not visible on the outer surface, which does not affect the decorative and beautification process of the column appearance.

[0040] See also Figure 1-Figure 4 , Figure 1 A three-dimensional diagram of a column of a calibration device provided in an embodiment of the present application is shown, Figure 2 A three-dimensional diagram of a column body provided in an embodiment of the present application is shown. Figure 3 A schematic cross-sectional view of a column of a calibration device provided in an embodiment of the present application is shown. Figure 4 Shows Figure 3 A partial enlarged schematic diagram. As shown in the figure, the column 100 of the calibration equipment includes: a column body 110, a first front cover plate 120 and a second front cover plate 130. The interior of the column body 110 is used to install a lifting mechanism (not shown in the figure), and the exterior of the column body 110 is used to install a crossbeam (not shown in the figure). An opening A is formed on one side of the column body 110, and the inner walls of the column body 110 on both sides of the opening are respectively provided with slide grooves 113 extending in the vertical direction. The first front cover plate 120 is partially inserted into one of the slide grooves 113, and the second front cover plate 130 is partially inserted into the other slide groove 113, so that the first front cover plate 120 and the second front cover plate 130 jointly cover part of the opening, and a gap B is left between the first front cover plate 120 and the second front cover plate 130, and the gap B is used for the lifting mechanism installed inside the column body 110 and the crossbeam installed outside the column body 110 to be fixedly connected, so that the lifting mechanism drives the crossbeam to move up and down on the column body 110.

[0041] Specifically, the two side plates of the column body 110 are formed as follows: Figure 2 The opening A shown in the figure, and the inner walls of the two side panels are along Figure 1 A slide groove 113 is extended in the direction of the middle arrow. This embodiment does not limit the specific shape of the slide groove 113, nor does it limit the specific length of the slide groove 113. The first front cover plate 120 and the second front cover plate 130 can be inserted into the slide groove 113 and fixed on one side of the column body 110.

[0042] The first front cover plate 120 and the second front cover plate 130 can be completely the same. The first front cover plate 120 is partially inserted into one of the slide grooves 113, and the second front cover plate 130 is partially inserted into the other slide groove 113, which can mean that the opposite sides of the first front cover plate 120 and the second front cover plate 130 can be directly inserted into the two slide grooves 113 respectively; or Figure 4 A slide bar 121 adapted to the slide groove 113 is extended from one side of the first front cover plate 120 and the second front cover plate 130, and the slide bars 121 of the first front cover plate 120 and the second front cover plate 130 are respectively inserted into the two slide grooves 113, wherein the slide bar 121 is adapted to the slide groove 113 means that the slide bar 121 can be just inserted into the slide groove 113.

[0043] When the first front cover plate 120 and the second front cover plate 130 are inserted into the slide groove 113, the first front cover plate 120 and the second front cover plate 130 can be fixed to each other with the column body 110, so that the first front cover plate 120 and the second front cover plate 130 jointly cover part of the opening, and a gap B exists between the first front cover plate 120 and the second front cover plate 130, so that the first front cover plate 120 and the second front cover plate 130 can block the lifting mechanism installed in the column body 110 and moving up and down in the column body 110, and the gap B can enable the lifting mechanism to drive the cross bar fixedly connected thereto and installed outside the column body 110 to move up and down.

[0044] The column 100 of the calibration device provided in the embodiment of the present application can quickly complete the installation of the front cover of the calibration device by respectively inserting the first front cover plate 120 and the second front cover plate 130 into the slide grooves 113 of the inner walls on both sides of the opening of the column body 110, thereby covering the lifting mechanism in the column body 110; and can quickly complete the disassembly of the front cover of the calibration device by pulling the first front cover plate 120 and the second front cover plate 130 out of the slide groove 113. The operation is convenient and fast, which reduces the assembly and disassembly time of the staff. At the same time, since the front cover plate and the side panel of the column body are fixed by plug-in connection, the fastening screws are not visible on the outer surface, which does not affect the decorative and beautifying process of the column appearance.

[0045] In order to prevent the first front cover plate 120 and the second front cover plate 130 from sliding out or being pulled out in the horizontal direction, the present application further proposes an implementation method, please continue to refer to Figure 4 As shown in the figure, the slide groove 113 and the slide bar 121 are engaged with each other in the horizontal direction.

[0046] In the embodiment of the present application, the slide groove 113 and the slide bar 121 are mutually engaged, and the shapes of the slide groove 113 and the slide bar 121 are not specifically limited while ensuring that the slide bar 121 cannot slide out of the slide groove 113 in the horizontal direction or be pulled out by external force. For example, the cross section of the slide groove 113 can also be as follows: Figure 4 The cross section of the slide bar 121 is a structure with a circular protrusion; the cross section of the slide groove 113 can also be as follows Figure 5 The cross section of the slide bar 121 is a structure with a rectangular protrusion; the cross section of the slide groove 113 can be as follows: Figure 6 The slide bar 121 has an open triangular structure, and the cross section of the slide bar 121 has a triangular protrusion structure.

[0047] In order to reduce the degree of deformation and damage to the slide slot 113 when installing and removing the first front cover plate 120 and the second front cover plate 130, the present application further proposes an implementation method, please continue to refer to Figure 3 and Figure 4 As shown in the figure, the first front cover plate 120 and the second front cover plate 130 have opposite sides that extend vertically inward to form a folded edge 122, and the slide bar 121 is arranged on the two opposite sides of the two folded edges 122, so that after the slide bar 121 is inserted into the slide groove 113, the outer surface of the first front cover plate 120 and the second front cover plate 130 is flush with the side where the opening on the column body 110 is located.

[0048] Specifically, in order to ensure the stability of the beam installed outside the column body 110 during the up and down lifting process, the outer surfaces of the first front cover plate 120 and the second front cover plate 130 are arranged flush with the side where the opening of the column body 110 is located. In this case, when the folded edges 122 of the first front cover plate 120 and the second front cover plate 130 are both extended vertically toward the interior of the column body 110, the slide strips 121 arranged on the two opposite sides of the two folded edges 122 are deeper into the interior of the column body 110; therefore, the slide groove 113 does not need to be arranged on the edge of the side where the two side plates of the column body 110 form an opening, but can be arranged on the inner wall of the two side plates closer to the interior of the column body 110, so that the outer surface of the first front cover plate 120 and the second front cover plate 130 are flush with the side where the two side plates of the column body 110 form an opening, so as to reduce the degree of deformation and damage to the structure at the slide groove 113 during the installation and removal of the first front cover plate 120 and the second front cover plate 130, thereby extending the service life of the column body 110.

[0049] In some embodiments, see Figure 4 When the slide bars 121 of the first front cover plate 120 and the second front cover plate 130 are respectively inserted into the slide grooves 113, the folded edges 122 of the first front cover plate 120 and the second front cover plate 130 are in contact with the two side plates of the column body 110, which can reduce the resistance in the process of inserting or withdrawing the slide bars 121 of the first front cover plate 120 and the second front cover plate 130 into or out of the slide grooves 113, thereby making it easier to install and remove the first front cover plate 120 and the second front cover plate 130.

[0050] In order to fix the first front cover plate 120 and the second front cover plate 130, the present application further proposes an implementation method, please continue to refer to Figure 1 As shown in the figure, the column 100 of the calibration device also includes a bottom plate 140 and a top plate 150, and the two ends of the column body 110 are detachably fixedly connected to the bottom plate 140 and the top plate 150. The two ends of the first front cover plate 120 and the second front cover plate 130 are detachably fixedly connected to the bottom plate 140 and the top plate 150.

[0051] Specifically, the bottom plate 140 and the top plate 150 may be respectively provided with slots that can engage with the column body 110, the first front cover plate 120 and the second front cover plate 130, so that when assembling the column 100 of the calibration device, one end of the column body 110 can be inserted into the slot of the bottom plate 140, and one end of the first front cover plate 120 and the second front cover plate 130 can be inserted into the slot of the bottom plate 140, and then the assembly of the column 100 of the calibration device can be quickly completed by inserting the other ends of the column body 110, the first front cover plate 120 and the second front cover plate 130 into the slots of the top plate 150 respectively; when disassembling the column 100 of the calibration device, the top plate 150 of the bottom plate 140 can be respectively pulled out, and then the first front cover plate 120 and the second front cover plate 130 can be respectively pulled out from the slide groove 113, so that the disassembly of the column 100 of the calibration device can be quickly completed, thereby facilitating the transportation of the calibration device.

[0052] In order to improve the connection stability between the column body 110 and the bottom plate 140 and the top plate 150, please continue to refer to Figure 3 , and combined with Figure 7 and Figure 8 , Figure 7 and Figure 8The schematic diagrams of the structures of the bottom plate and the top plate provided in the embodiment of the present application are respectively shown. As shown in the figure, a plurality of first fixing holes 114 can be respectively provided at both ends of the column body 110, and a second fixing hole 115 can be provided at a position corresponding to each first fixing hole 114 of the bottom plate 140 and the top plate 150. Then, by connecting and fixing the first fixing hole 114 and the second fixing hole 115, the column body 110 is respectively fixedly connected to the bottom plate 140 and the top plate 150. For example, the first fixing hole 114 and the second fixing hole 115 can be bound by a metal wire, or the first fixing hole 114 and the second fixing hole 115 can be fixed by nuts and bolts.

[0053] Similarly, in order to improve the connection stability between the pillar body 110 and the first front cover plate 120 and the second front cover plate 130, please continue to refer to Figure 3 , Figure 7 and Figure 8 , a third fixing hole 123 may be provided at both ends of the first front cover plate 120 and the second front cover plate 130 facing each other, and a fourth fixing hole 124 may be provided at the positions of the bottom plate 140 and the top plate 150 corresponding to the third fixing hole 123, so that the bottom plate 140 may be fixedly connected to the first front cover plate 120 and the second front cover plate 130 respectively, and the top plate 150 may be fixedly connected to the first front cover plate 120 and the second front cover plate 130 respectively by connecting and fixing the third fixing hole 123 and the fourth fixing hole 124. For example, the third fixing hole 123 and the fourth fixing hole 124 may be bound by a metal wire, or the third fixing hole 123 and the fourth fixing hole 124 may be fixed by nuts and bolts. In the above manner, the first front cover plate 120 and the second front cover plate 130 can be detachably fixed on the column body 110 without using fastening screws on the outside of the column body 110, and since the fixed connection structures are located at both ends of the column 100 and can be hidden inside the column body 110, it is possible to avoid affecting the appearance decoration and beautification process of the column 100.

[0054] In order to facilitate the installation and removal of the first front cover plate 120 and the second front cover plate 130, the present application further proposes an implementation method, please continue to refer to Figure 3 , Figure 7 and Figure 8 As shown in the figure, the first fixing hole 114 and the third fixing hole 123 are both threaded holes. The first fixing hole 114 is fixedly connected to the second fixing hole 115 by a threaded fastener, and the third fixing hole 123 is fixedly connected to the fourth fixing hole 124 by a threaded fastener.

[0055] The second fixing hole 115 and the fourth fixing hole 124 can be set as through holes, in which case screws can be used as threaded fasteners; the second fixing hole 115 and the fourth fixing hole 124 can also be set as threaded holes, in which case studs and screws can be used as threaded fasteners.

[0056] The first fixing hole 114 and the third fixing hole 123 are set as threaded holes. The first front cover plate 120 and the second front cover plate 130 can be connected and fixed to the bottom plate 140 and the top plate 150 respectively only by passing the threaded fastener through the second fixing hole 115 and screwing it into the first fixing hole 114, and passing the threaded fastener through the fourth fixing hole 124 and screwing it into the third fixing hole 123. This is convenient, fast and easy to install, and can save time for installing and disassembling the first front cover plate 120 and the second front cover plate 130.
