The appearances of the phrase“in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily all referring to a common embodiment, or an embodiment that is independent of other embodiments. One of ordinary skill in the art will readily recognize from the disclosure herein the possibility of combining features of different embodiments.

[0039] The following will be described in detail Figures 1 to 8 The beam module 30, the calibration device 100 and the calibration system provided by the embodiments of the application will be described in detail.

[0040] Please refer to Figure 1 And Figure 2 , Figure 1 is a perspective view of the calibration device 100 in a working state (the beam is in an unfolded state), Figure 2 is a perspective view of the calibration device 100 in a storage state (the beam is in a folded state).

[0041] The embodiments of the application provide a calibration device 100, and the ADAS system can be calibrated by the calibration device 100. The calibration device 100 comprises a base 10, a stand column 20 and a beam module 30. The stand column 20 is vertically arranged on the base 10, and the beam module 30 is installed on the stand column 20.

[0042] The base 10 is usually made of high-strength materials, such as cast iron or steel, so as to provide stable and reliable support for the entire calibration device 100. Optionally, the bottom of the base 10 is provided with a roller, so as to facilitate the movement of the calibration device 100.

[0043] The stand column 20 can be in a rod or column structure, and the stand column 20 can be made of high-strength aluminum alloy or steel, so as to ensure sufficient strength and rigidity. The bottom end of the stand column 20 is vertically connected to the base 10. Optionally, the bottom end of the stand column 20 can be detachably installed on the base 10 by clamping, screwing or the like, so as to facilitate the disassembly and assembly of the stand column 20.

[0044] The beam module 30 can be made of relatively light and high-strength materials, such as aluminum alloy profiles, so as to reduce the weight while ensuring sufficient rigidity. The beam module 30 can be slidably installed on the stand column 20, so as to facilitate the adjustment of the installation height of the beam module 30 on the stand column 20.

[0045] Optionally, the crossbeam module 30 has an unfolded state and a folded state. When the crossbeam module 30 is unfolded in a straight line, the length of the entire crossbeam module 30 can be maximally extended, facilitating calibration work using the crossbeam module 30. When the calibration device 100 needs to be stored, the crossbeam module 30 can be folded to reduce the overall volume of the calibration device 100, improving the portability and flexibility of the calibration device 100.

[0046] Please refer to Figures 3 to 5 , Figure 3 is a perspective view of the crossbeam module 30, Figure 4 is a cross-sectional view of the crossbeam module 30 with the crossbeam 31 in the unfolded state, Figure 5 is Figure 4 is an enlarged view of part A in FIG. 8.

[0047] In some embodiments, the crossbeam module 30 includes a crossbeam 31 and a drag chain 32. The crossbeam 31 is foldably arranged, and a receiving cavity 310 is formed in the crossbeam 31. The drag chain 32 is installed in the receiving cavity 310 and is arranged along the length direction of the crossbeam 31. The drag chain 32 is provided with a wire routing groove 320 along the length direction thereof for routing a wire.

[0048] Specifically, the crossbeam 31 is foldably arranged so that it can be unfolded in a straight line when the calibration device 100 is in use, meeting the spatial requirements of calibration work. When storage is required, the crossbeam 31 can be folded, effectively reducing the overall volume of the calibration device 100 and improving the portability and flexibility of the device, facilitating transportation and storage.

[0049] The crossbeam 31 is hollow inside and forms a receiving cavity 310 for receiving the drag chain 32. The drag chain 32 can have a chain-like structure. The drag chain 32 is installed in the receiving cavity 310 and is arranged along the length direction of the crossbeam 31, so that the drag chain 32 is hidden in the receiving cavity 310 of the crossbeam 31, improving the appearance neatness of the calibration device 100.

[0050] The wire routing groove 320 is arranged along the length direction of the drag chain 32 for routing the wire. By placing the wire in the wire routing groove 320 of the drag chain 32 and hiding the drag chain 32 in the receiving cavity 310 of the crossbeam 31, the drag chain 32 can adjust its position accordingly during the unfolding and folding of the crossbeam 31. The wire is always in a relatively stable and protected environment, preventing the wire from being damaged by pulling, abrasion, winding, etc. during the unfolding or folding of the crossbeam 31, ensuring the integrity and normal working performance of the wire, improving the service life and reliability of the cable, and avoiding the tedious operation of repeatedly disassembling and connecting the wire when switching between the folded and unfolded states of the crossbeam 31, saving a lot of time and labor costs.

[0051] It can be understood that, in the process of folding the cross beam 31, the drag chain 32 located inside the cross beam 31 will change its form accordingly following the folding process of the cross beam 31, and finally present a folding form adapted to the folding state of the cross beam 31.

[0052] In some embodiments, the cross beam 31 comprises a first cross beam part 311 and a second cross beam part 312 arranged foldably, a first mounting cavity 3110 is formed in the first cross beam part 311, a second mounting cavity 3120 is formed in the second cross beam part 312, the first mounting cavity 3110 and the second mounting cavity 3120 are connected and form a receiving cavity 310, a part of the drag chain 32 is received in the first mounting cavity 3110, another part of the drag chain 32 is received in the second mounting cavity 3120, one end of the drag chain 32 is connected with the first mounting cavity 3110, and the other end of the drag chain 32 is connected with the second mounting cavity 3120.

[0053] The first cross beam part 311 and the second cross beam part 312 can be hollow tubular structures, the first cross beam part 311 and the second cross beam part 312 form the first mounting cavity 3110 and the second mounting cavity 3120 respectively, and the two ends of the drag chain 32 are connected in the first mounting cavity 3110 and the second mounting cavity 3120 respectively.

[0054] Optionally, the first cross beam part 311 and the second cross beam part 312 can be folded and unfolded through a hinge structure, in the unfolded state, the first cross beam part 311 and the second cross beam part 312 are arranged horizontally and collinearly, and the first cross beam part 311 and the second cross beam part 312 are accurately aligned in the length direction thereof. When folding is needed, the first cross beam part 311 and the second cross beam part 312 are rotated to make the first cross beam part 311 and the second cross beam part 312 close to each other and present a generally vertical state, and the folding of the cross beam 31 is completed. Optionally, when the cross beam 31 is folded, the cross beam 31 is first slid to the bottom of the stand column 20, and then the first cross beam part 311 and the second cross beam part 312 are rotated upward to the vertical state, and the folding of the cross beam 31 is completed (see Figure 2 ).

[0055] It can be understood that, when the first cross beam part 311 and the second cross beam part 312 are in the folded state, the drag chain 32 located in the first cross beam part 311 will be in a generally vertical state, and the drag chain 32 located in the second cross beam part 312 will also be in a generally vertical state, and the part of the drag chain 32 connecting the first cross beam part 311 and the second cross beam part 312 will form a curved transition area to adapt to the angle change caused by the folding of the cross beam 31, so that the drag chain 32 will form a generally "U" shaped structure when the cross beam 31 is in the folded state.

[0056] Please refer to Figures 6 to 8 , Figure 6 is a schematic view of the three-dimensional structure of the drag chain 32,Figure 7 is a schematic diagram of the three-dimensional structure of the assembled drag chain 32 and elastic member 33, Figure 8 is a schematic diagram of the three-dimensional structure of the hinge unit 323.

[0057] In some embodiments, the drag chain 32 includes a first chain 321 and a second chain 322 connected together, the first chain 321 is connected to the first mounting cavity 3110 at one end away from the second chain 322, and the second chain 322 is connected to the second mounting cavity 3120 at one end away from the first chain 321; when the crossbeam 31 is in the extended state, the first chain 321 is arranged along the length direction of the crossbeam 31, and the second chain 322 is bent towards one side of the first chain 321.

[0058] As shown in Figure 6 , the first chain 321 and the second chain 322 are connected and constitute the drag chain 32, one part of the first chain 321 is located in the first mounting cavity 3110, another part of the first chain 321 is located in the second mounting cavity 3120, and the second chain 322 is located in the second mounting cavity 3120.

[0059] When the crossbeam 31 is in the extended state, the first chain 321 is arranged in a straight line, and the second chain 322 is bent towards one side of the first chain 321, so that the second chain 322 partially overlaps the first chain 321 in the vertical direction.

[0060] During the process of switching the crossbeam 31 from the extended state to the folded state, the second chain 322 provides additional length and flexibility, so that the second chain 322 can jointly constitute a "U"-shaped drag chain 32 structure with the first chain 321, ensuring that the drag chain 32 can smoothly complete the conversion from the extended state to the folded state. In other words, without the second chain 322, the drag chain 32 is likely to be excessively stretched during the folding process due to its too short length, thereby damaging the structure of the drag chain 32 or affecting the normal wiring of the internal wires.

[0061] As shown in Figure 7 , in some embodiments, the crossbeam module 30 further includes an elastic member 33, which is installed on the drag chain 32 and arranged along the length direction of the drag chain 32. The elastic member 33 is used to provide a restoring force for the drag chain 32 to return to its original shape, ensuring that the drag chain 32 can automatically adjust and maintain a good shape during the unfolding and folding process of the crossbeam 31.

[0062] Specifically, when the crossbeam 31 is in the extended state, the first chain 321 is arranged in a straight line inside the crossbeam 31, and the elastic member 33 can be arranged along the length direction of the first chain 321.

[0063] When the cross beam 31 is switched from the unfolded state to the folded state, the elastic member 33 will be elastically deformed with the movement of the cross beam 31 and the drag chain 32 and store elastic potential energy. When the cross beam 31 is restored from the folded state to the unfolded state, the stored elastic potential energy forms a restoring force and provides power support for the rebound of the drag chain 32, ensuring that the drag chain 32 can be accurately and smoothly restored, so that the wires remain in a suitable connection and wiring state, effectively avoiding the problems of wire entanglement and poor connection caused by the failure of the drag chain 32 to be restored in time.

[0064] In some embodiments, the elastic member 33 is an elastic sheet, and the elastic sheet is installed in the wire slot 320. The elastic member 33 can be an elastic sheet in a generally long strip structure, which can be more conveniently installed in the wire slot 320 of the drag chain 32. The wire slot 320 provides a certain protection and hiding effect for the elastic sheet, avoiding interference and damage of the elastic sheet by external factors. Moreover, the elastic member 33 can be reasonably arranged according to the shape and size of the wire slot 320, without occupying too much additional space, which is conducive to maintaining the compactness of the device structure.

[0065] In addition, the installation of the elastic sheet in the wire slot 320 can make the elastic sheet closely combined with the drag chain 32 and the wires therein. During the movement of the drag chain 32, the elastic sheet can directly act on the drag chain 32, better guiding the deformation and restoration of the drag chain 32, ensuring that the wires are always in a relatively stable position during the movement of the drag chain 32, and reducing the problems of wire displacement and shaking that may be caused by the separation or indirect action of the elastic member 33 and the drag chain 32.

[0066] As shown in Figure 5 In some embodiments, the cross beam module 30 further includes a guide wheel 34, which is arranged in the accommodation cavity 310 and guides the drag chain 32.

[0067] Specifically, the guide wheel 34 can be arranged in the first mounting cavity 3110, the second mounting cavity 3120, or the junction of the first mounting cavity 3110 and the second mounting cavity 3120. The guide wheel 34 can be provided with one or more, for example, the guide wheel 34 can have multiple. The cavity wall of the first mounting cavity 3110 and the cavity wall of the second mounting cavity 3120 are respectively provided with an axle, and each guide wheel 34 is respectively installed on the corresponding axle.

[0068] Optionally, the cavity wall of the accommodation cavity 310 is provided with an axle, and the guide wheel 34 is installed on the axle. The guide wheel 34 has a supporting and guiding effect on the drag chain 32. During the unfolding and folding of the cross beam 31, the drag chain 32 will slide along the guide wheel 34, avoiding friction between the drag chain 32 and the cavity wall of the accommodation cavity 310, and ensuring the smoothness and stability during the sliding process.

[0069] As shown in Figure 7 andFigure 8 As shown, in some embodiments, the drag chain 32 comprises a plurality of hinge units 323, and two adjacent hinge units 323 are hingedly connected.

[0070] Specifically, the structure of each hinge unit 323 can be the same, and the hinge units 323 are hingedly connected in sequence to facilitate the assembly of the drag chain 32 into any length, which helps to improve the versatility and applicability of the drag chain 32. It can be understood that the first chain 321 and the second chain 322 described above are both composed of a plurality of hinge units 323 hingedly connected.

[0071] The hingedly connected hinge units 323 enable the drag chain 32 to flexibly bend and stretch, so as to better adapt to the conversion of the cross beam 31 between the unfolded and folded states. When the cross beam 31 switches from the unfolded state to the folded state, or recovers from the folded state to the unfolded state, the hingedly connected hinge units 323 can flexibly adjust their own shapes according to the shape change of the cross beam 31, avoiding the rigidity of the drag chain 32 being too high to adapt to the structural change, and ensuring that the drag chain 32 can smoothly change shape following the movement of the cross beam 31.

[0072] In some embodiments, the hinge unit 323 comprises a hinge body 3230, a first hinge part 3231 and a second hinge part 3233, the hinge body is provided with a wire slot 320, the first hinge part 3231 and the second hinge part 3233 are respectively arranged at opposite ends of the hinge body, and the first hinge part 3231 of one of the two adjacent hinge units 323 is hingedly connected with the second hinge part 3233 of the other hinge unit 323.

[0073] The hinge body 3230, the first hinge part 3231 and the second hinge part 3233 can be integrally formed to ensure the structural strength.

[0074] The wire slot 320 is arranged on the hinge body of each hinge unit 323, and the wire can be sequentially arranged in the wire slots 320 on the hinge bodies, so that the wire is orderly arranged inside the drag chain 32. The elastic member 33 can also be sequentially arranged in the wire slots 320 on the hinge bodies to complete the installation of the elastic member 33 in the wire slots 320.

[0075] Optionally, one of the first hinge part 3231 and the second hinge part 3233 is provided with a hinge hole 3232, and the other is provided with a hinge shaft 3234, and the hinge shaft 3234 of one of the two adjacent hinge units 323 is inserted into the hinge hole 3232 of the other hinge unit 323, so as to realize the hingedly connection of the two adjacent hinge units 323.

[0076] In some embodiments, one end of the drag chain 32 is provided with a first connecting piece 324, and the other end of the drag chain 32 is fixedly connected with the cavity wall of the second mounting cavity 3120 through the second connecting piece 325.

[0077] As shown in the drawings, the first connecting piece 324 and the second connecting piece 325 can have the same structure. Figure 6 The first connecting piece 324 and the second connecting piece 325 can have a block structure, the first connecting piece 324 is fixedly connected with one end of the drag chain 32, and the first connecting piece 324 can be fixedly connected with the cavity wall of the first mounting cavity 3110 through screws, bolts or other fasteners.

[0078] Based on the same inventive concept, the utility model further provides a calibration system, which comprises the calibration device 100 and a diagnostic instrument.

[0079] The diagnostic instrument can be a tablet diagnostic instrument, so as to facilitate carrying and transportation.

[0080] Optionally, the calibration system can further comprise a target, a mirror, a laser and other calibration elements, which can be installed on the cross beam 31.
