[0037] Example:

[0038] This utility model provides a vehicle measuring device, including a base, a column mounted on the base, and a crossbeam module mounted on the column. A component to be installed is mounted on the crossbeam module, wherein the component to be installed can be a camera assembly or a calibration assembly.

[0039] Please see Figures 1 to 8 The crossbeam module includes a crossbeam part 1, a guide 2, and a sliding part 3. The crossbeam part 1 is provided with a slide groove 121; the guide 2 is disposed in the slide groove 121, and the length of the guide 2 extends along the length direction of the slide groove 121; the sliding part 3 is slidably assembled in the slide groove 121 and rolls with the guide 2, and the sliding part 3 is used to install the component to be installed.

[0040] By setting a guide 2 in the slide groove 121 and making the guide 2 roll with the sliding part 3, the sliding part 3 can slide more stably under the guidance of the guide 2 and slide more smoothly under the rolling action, thereby reducing shaking and improving the smoothness and stability of the sliding part 3 when sliding on the crossbeam part 1.

[0041] Please see Figure 2 , Figure 4 and Figure 6In some embodiments, the sliding portion 3 includes a slider 31 and a rolling element 32. The slider 31 is slidably fitted within the groove 121 and is used to install the component to be installed. The rolling element 32 is rotatably connected to the slider 31 and has an annular receiving groove 321. The central axis of the receiving groove 321 is coaxially arranged with the axis of rotation between the rolling element 32 and the slider 31. The guide element 2 is received within the receiving groove 321 and rolls with the rolling element 32. Thus, the rolling engagement between the guide element 2 and the slider 31 is achieved through the rolling element 32, resulting in a simple structure.

[0042] Please see Figure 4 In some embodiments, multiple rolling elements 32 are provided, and the multiple rolling elements 32 are distributed at intervals or continuously along the sliding direction of the slider 31. In this way, by providing a larger number of rolling elements 32, the smoothness of the slider 31 sliding in the groove 121 can be improved.

[0043] In some embodiments, the guide member 2 may be disposed on the bottom wall of the slide 121.

[0044] Please see Figure 4 , Figure 6 and Figure 8 In some embodiments, the guide member 2 has a guide structure on the side near the receiving groove 321, and the guide structure is adapted to the receiving groove 321. The guide structure cooperates with the rolling member 32 to guide the sliding of the slider 31, thereby improving the smoothness of the sliding of the slider 31.

[0045] Depending on actual needs, the guide structure can be in the shape of an arc, V, U, etc. The guide structure can be integrally set with the guide member 2, that is, the guide structure is the part of the guide member 2 that extends into the receiving groove 321. For example, the guide member 2 can be a cylindrical rod; or, the guide structure and the guide member 2 can be set separately, and the guide structure can be a protrusion set on the guide member 2.

[0046] In some embodiments, the stiffness of the guide member 2 is greater than that of the crossbeam portion 1, and the guide member 2 is made of a metallic material. The guide member 2 can have reinforcing ribs formed on the crossbeam portion 1, thereby improving the load-bearing strength and stiffness of the crossbeam portion 1, effectively preventing bending deformation of the crossbeam portion 1, and improving calibration accuracy. Furthermore, the guide member 2 made of metallic material is wear-resistant and has a lower cost.

[0047] Depending on actual needs, the metal material can be iron, chromium, manganese, etc., and the guide can be a steel rod. The two ends of the guide 2 are flush with the two ends of the crossbeam part 1.

[0048] Please see Figure 4 , Figure 6 and Figure 8In some embodiments, the sliding portion 3 further includes a fixing portion 33 and a connecting shaft 34. The fixing portion 33 is disposed on the slider 31; the connecting shaft 34 is rotatably connected to the fixing portion 33, and the rolling element 32 is sleeved and fixed on the outside of the connecting shaft 34; wherein the number of fixing portions 33, connecting shafts 34 and rolling elements 32 are arranged in a one-to-one correspondence. In this way, the connecting shaft 34 is mounted on the slider 31 through the fixing portion 33, and the connecting shaft 34 is the rotation axis between the rolling element 32 and the slider 31. The rolling element 32 can rotate relative to the slider 31, realizing the rolling engagement between the rolling element 32 and the crossbeam portion 1.

[0049] Please see Figure 4 and Figure 6 In some embodiments, the slider 31 is provided with a mounting hole 313, and the fixing part 33 is assembled in the mounting hole 313, and the fixing part 33 is detachably connected to the slider 31. In this way, it is convenient to fix the fixing part 33 on the slider 31; wherein, the mounting hole 313 is adapted to the fixing part 33, for example, the fixing part 33 may be disc-shaped, and the mounting hole 313 may be a round hole.

[0050] It should be noted that the fixing part 33 abuts against the bottom wall of the mounting hole 313, which can prevent the connecting shaft 34 and the rolling element 32 from moving axially, thereby limiting the rolling element 32.

[0051] Please see Figure 8 In some embodiments, the fixing part 33 and the rolling element 32 are respectively located at both ends of the connecting shaft 34. The bottom wall of the mounting hole 313 is provided with threaded holes. The fixing part 33 is locked into the threaded holes by screws, thereby fixing the fixing part 33 to the slider 31 by screws. Furthermore, multiple threaded holes can be provided at intervals on the bottom wall of the mounting hole 313. After multiple screws are inserted into the fixing part 33, they are screwed into the corresponding threaded holes. By adjusting the screws, the specific position and angle of the rolling element 32 can be finely adjusted.

[0052] Please see Figure 7 In some embodiments, the crossbeam portion 1 has a first sidewall 122 and a second sidewall 123 that are relatively distributed along the length of the slide groove 121, and the guide member 2 is disposed on the first sidewall 122 and / or the second sidewall 123. In this way, the guide member 2 can provide lateral support to the slider 31, which can effectively prevent the slider 31 from shaking during sliding and further improve the stability of the slider 31 sliding.

[0053] Please see Figure 7 In a specific example, guide members 2 are respectively provided on the first sidewall 122 and the second sidewall 123, and the guide members 2 on the first sidewall 122 and the second sidewall 123 are symmetrically arranged.

[0054] In some embodiments, multiple guide members 2 may be provided on the first sidewall 122 and the second sidewall 123, and multiple receiving grooves 321 may be provided on the rolling member 32, with the multiple guide members 2 being received one-to-one in the multiple receiving grooves 321. In this way, the rolling cooperation between the multiple guide members 2 and the multiple rolling members 32 is beneficial to improving the smoothness and stability of the sliding of the slider 31.

[0055] Please see Figure 7 and Figure 8 In some embodiments, the guide member 2 is detachably connected to the crossbeam portion 1. The first side wall 122 and the second side wall 123 are both provided with a surrounding receiving structure. The surrounding receiving structure can be an arc-shaped structure with a bending angle greater than 180°. The guide member 2 is housed in the surrounding receiving structure, thereby realizing the detachable connection between the guide member 2 and the crossbeam portion 1.

[0056] Please see Figure 7 and Figure 8 In some embodiments, both the first sidewall 122 and the second sidewall 123 are provided with mounting grooves 124, and the guide member 2 is assembled in the mounting groove 124. The side of the guide member 2 near the mounting groove 124 is provided with a smooth transition structure, and the length of the cross-section of the guide member 2 gradually increases and then gradually decreases, thereby facilitating the installation of the guide member 2 in the mounting groove 124. The surrounding receiving structure can be the mounting groove 124, and the smooth transition structure can be the arc surface structure on the guide member 2.

[0057] Please see Figure 4 , Figure 5 and Figure 7 In some embodiments, the slider 31 has a clearance groove 311 on the side near the guide member 2, and the guide member 2 is housed in the clearance groove 311, with a gap between the guide member 2 and the inner wall of the clearance groove 311. Thus, when the guide member 2 contacts the rolling member 32, the clearance groove 311 prevents the guide member 2 from directly contacting the slider 31; that is, the guide member 2 only contacts the slider 31 through the rolling member 32, resulting in less friction and improving the smoothness of the slider 31 sliding on the crossbeam portion 1.

[0058] Please see Figure 2 , Figure 4 and Figure 7 In some embodiments, a limiting part 312 is provided at the end of the slider 31. The limiting part 312 is slidably fitted in the slide groove 121, and the clearance groove 311 is located on the side of the limiting part 312 near the guide member 2. In this way, the limiting part 312 cooperates with the first side wall 122 and the second side wall 123 to restrict the vertical movement of the slider 31; the guide member 2 is housed in the clearance groove 311, so that the guide member 2 can cooperate with the limiting part 312 to restrict the forward and backward movement of the slider 31, thereby effectively preventing the slider 31 from shaking during sliding and improving the stability of the slider 31 sliding.

[0059] Please see Figure 4 and Figure 5 In some embodiments, the slider 31 is provided with limiting parts 312 at both ends. The vertical cross-section shape of the slider 31 at both ends can be T-shaped, wherein the vertical cross-section direction is basically parallel to the length direction of the column. A cavity is formed between the two limiting parts 312, and the rolling element 32 is disposed in the cavity between the two limiting parts 312.

[0060] In some embodiments, the clearance groove 311 is adapted to the guide member 2, and the clearance groove 311 is an arc-shaped groove. This helps to prevent the guide member 2 from contacting the inner wall of the clearance groove 311.

[0061] Depending on actual needs, guide 2 can be a cylinder.

[0062] Please see Figure 1 , Figure 2 and Figure 7 In some embodiments, the crossbeam portion 1 includes a crossbeam body 11 and a guide rail 12. The guide rail 12 is detachably connected to the crossbeam body 11 and is provided with a groove 121. The guide rail 12 has a first sidewall 122 and a second sidewall 123 that are relatively distributed along the length of the groove 121. In this way, the guide member 2 is installed on the guide rail 12, which facilitates the installation and removal of the guide member 2. The slider 31 is slidably assembled on the guide rail 12. Compared with the slider 31 being directly slidably assembled on the crossbeam body 11, the processing and installation of the guide rail 12 is simpler, thereby reducing the processing difficulty and assembly difficulty.

[0063] Please see Figure 7 In some embodiments, both the first sidewall 122 and the second sidewall 123 are provided with mounting grooves 124, and the guide member 2 is assembled in the mounting grooves 124. In this way, the installation difficulty of the guide member 2 can be reduced.

[0064] Please see Figure 1 and Figure 2 In some embodiments, the crossbeam portion 1 is provided with multiple segments distributed along its length, and two adjacent crossbeam portions 1 are connected by a folding structure 5, thereby facilitating the storage of the crossbeam portion 1.

[0065] Please see Figure 2In some embodiments, the folding structure 5 includes a first folding seat 51, a first rotating shaft 53, a second folding seat 52, and a locking assembly 54. The first folding seat 51 and the second folding seat 52 are respectively disposed on two adjacent crossbeam sections 1. The first rotating shaft 53 is disposed on the first folding seat 51. The second folding seat 52 is rotatably connected to the first rotating shaft 53. The axial extension direction of the first rotating shaft 53 is perpendicular to the length extension direction of the crossbeam section 1. The locking assembly 54 is movably disposed on the second folding seat 52 and is engaged with the first folding seat 51, thereby locking the second folding seat 52 on the first folding seat 51.

[0066] In some embodiments, the locking component 54 includes a latch, an elastic element, and a second rotating shaft. The latch is rotatably connected to the second folding seat 52 via the second rotating shaft, and the latch is engaged with the first folding seat 51. The elastic element is connected between the second folding seat 52 and the latch, so that the latch can be reset after release.

[0067] In some embodiments, the guide member 2 is provided with multiple segments, and the multiple segments of the guide member 2 are continuously arranged along the length direction of the crossbeam portion 1. In this way, it is possible to avoid assembling an entire guide member 2 onto the crossbeam portion 1, reducing the assembly difficulty; moreover, the multiple segments of the guide member 2 are assembled one-to-one onto the multiple segments of the crossbeam portion 1, thereby cooperating with the segmented crossbeam portion 1.

[0068] Please see Figure 1 and Figure 2 In some embodiments, the crossbeam module further includes a connecting seat 4 disposed on the side of the slider 31 away from the crossbeam portion 1, the connecting seat 4 being used to mount the component to be mounted. Thus, the component to be mounted can be conveniently mounted on the slider 31 via the connecting seat 4; wherein the connecting seat 4 and the slider 31 are detachably connected, for example, the connecting seat 4 and the slider 31 can be connected by screws.

[0069] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
