[0036] Example:

[0037] This utility model provides a vehicle measuring device, including a calibration bracket on which a component to be installed can be mounted, wherein the component to be installed can be a camera assembly or a calibration assembly.

[0038] Please see Figures 1 to 6 In some embodiments, the calibration bracket includes a crossbeam portion 1, a base, a stand, and a sliding portion 3. The stand is mounted on the base, the crossbeam portion 1 is mounted on the stand, and the crossbeam portion 1 is movable relative to the stand along the length direction of the stand. The sliding portion 3 includes a slider 31 and a rolling element 32. The slider 31 is used to mount the component to be installed. The rolling element 32 is rotatably mounted on the slider 31 and rolls relative to the crossbeam portion 1 along the length direction of the crossbeam portion 1. There are multiple rolling elements 32, and the multiple rolling elements 32 are distributed at intervals or continuously along the sliding direction of the slider 31.

[0039] By providing a rolling element 32 between the slider 31 and the crossbeam portion 1, a rolling engagement is achieved between the slider 31 and the crossbeam portion 1, allowing the slider 31 to slide more smoothly on the crossbeam portion 1, reducing wobbling, and improving the smoothness and stability of the slider 31 when sliding on the crossbeam portion 1.

[0040] It should be noted that, in this embodiment of the utility model, the axis of rotation between the rolling element 32 and the slider 31 intersects with the sliding direction of the slider 31.

[0041] In some embodiments, the crossbeam portion 1 is provided with a groove 121, and the crossbeam portion 1 is provided with a first sidewall 122 and a second sidewall 123 distributed opposite to each other along the length of the groove 121; the rolling element 32 is received within the groove 121, and each rolling element 32 rolls into contact with at least one of the first sidewall 122 and the second sidewall 123. Thus, the rolling element 32 rolls into contact with at least one of the first sidewall 122 and the second sidewall 123, and the slider 31 is located within the groove 121, allowing the rolling element 32 to provide lateral support to the slider 31, further improving the stability of the slider 31 during sliding.

[0042] Depending on actual needs, a rolling element 32 can be configured to roll in cooperation with both the first sidewall 122 and the second sidewall 123, or a rolling element 32 can be configured to roll in cooperation with only the first sidewall 122 or the second sidewall 123.

[0043] Please see Figure 2 , Figure 3 and Figure 4 In some embodiments, multiple rolling elements 32 are arranged on the slider 31 to form multiple sets of rolling groups. Each set of rolling groups has multiple rolling elements 32 distributed along the sliding direction of the slider 31. At least one set of rolling groups contacts only the first sidewall 122, and at least one set contacts only the second sidewall 123. In this way, the slider 31 can maintain balance during sliding, thereby improving the stability of the slider 31 during sliding. Moreover, since the two sets of rolling groups contact the first sidewall 122 and the second sidewall 123 respectively, they can provide lateral support to the slider 31 from both sides of the crossbeam portion 1, which is beneficial to improving the stability of the slider 31 during sliding.

[0044] Please see Figure 2 and Figure 3 In some embodiments, the calibration bracket has two sets of rolling groups distributed on opposite sides of the slider 31. One set of rolling groups contacts only the first sidewall 122, and the other set contacts only the second sidewall 123. In this way, lateral support can be provided to the slider 31 from both sides of the crossbeam portion 1, improving the stability of the slider 31 during sliding.

[0045] Please see Figure 3In some embodiments, the rolling elements 32 in the two sets of rolling groups are staggered or directly opposite each other. Thus, the rolling elements 32 can be arranged on the slider 31 according to actual needs; wherein, when the space of the slide groove 121 is small, the rolling elements 32 in the two sets of rolling groups are staggered, that is, the rolling elements 32 of the two sets of rolling groups each form a row (a row along the direction of the first sidewall 122), and are arranged alternately at intervals; when a larger number of rolling elements 32 are needed, the rolling elements 32 in the two sets of rolling groups are directly opposite each other, that is, the two sets of rolling groups each form a row (a row along the direction of the first sidewall 122), and the two rolling elements 32 of different rolling groups are arranged in a row.

[0046] In some embodiments, the rolling assembly is provided in three groups, one of which is in contact with the first sidewall 122, one of which is in contact with the second sidewall 123, and one of which is in contact with both the first sidewall 122 and the second sidewall 123.

[0047] In some embodiments, the number of rollers 32 in the two roller groups 32 can be the same or different. For example, one group of rollers 32 may have three rollers and the other group may have two rollers.

[0048] Please see Figure 3 In a specific example, a set of rolling elements is provided on each of the opposite sides of the slider 31. The rolling elements 32 in the two sets of rolling elements are staggered. One set of rolling elements has two rolling elements 32, and the other set has three rolling elements 32.

[0049] It should be noted that the number of scroll groups and the number of scroll elements 32 are set according to actual needs.

[0050] In some embodiments, the calibration bracket further includes a guide member 2 disposed on the first sidewall 122 and / or the second sidewall 123. The rolling member 32 has an annular receiving groove 321, the central axis of which is coaxially arranged with the axis of rotation between the rolling member 32 and the slider 31. The guide member 2 is received within the receiving groove 321 and rolls with the rolling member 32. Thus, the rolling engagement between the guide member 2 and the slider 31 is achieved through the rolling member 32, resulting in a simple structure.

[0051] Please see Figure 3 and Figure 5 In some embodiments, the rolling element 32 is provided with two abutment rings 322, which are spaced apart by a receiving groove 321. Both abutment rings 322 are coaxially arranged with the pivot between the rolling element 32 and the slider 31. The abutment rings 322 and the crossbeam portion 1 make rolling contact, so that the crossbeam portion 1 can provide lateral support for the rolling of the rolling element 32, thereby improving the rolling stability of the rolling element 32.

[0052] It should be noted that when the vehicle measuring equipment is working, the first side wall 122 is on top and the second side wall 123 is on the bottom, and when the slider 31 slides, the outer side walls of the two abutting rings 322 roll against the second side wall 123.

[0053] Please see Figure 3 and Figure 5 In 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 pivot 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.

[0054] Please see Figure 3 and Figure 5 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.

[0055] 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.

[0056] In some embodiments, the fixing part 33 and the rolling element 32 are respectively disposed at both ends of the connecting shaft 34. The bottom wall of the mounting hole 313 is provided with a threaded hole. The fixing part 33 is locked into the threaded hole by a screw, thereby fixing the fixing part 33 to the slider 31 by the screw. 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.

[0057] Please see Figure 1 In some embodiments, at least three sliding portions 3 are provided, each sliding portion 3 is spaced apart on the crossbeam portion 1, and at least two sliding portions 3 are configured with different loads to install components of different weights. In this way, components of different weights can be installed through multiple sliding portions 3 with different loads, thereby improving adaptability.

[0058] Please see Figure 3 , Figure 4 and Figure 6 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.

[0059] Please see Figure 2 , Figure 3 and Figure 6 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.

[0060] Please see Figure 3 and Figure 4 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.

[0061] 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.

[0062] Please see Figure 1 , Figure 2 and Figure 6 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 rolls with the rolling element 32. The guide rail 12 has a groove 121, and a first sidewall 122 and a second sidewall 123 are provided oppositely distributed along the length of the groove 121. This simplifies the structure of the crossbeam portion 1, reduces processing and assembly difficulty, and the guide rail 12 guides the sliding of the slider 31.

[0063] Please see Figure 1 and Figure 2In some embodiments, the calibration bracket 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.

[0064] Furthermore, the connector 4 may be provided with a receiving structure and a calibration hole that connects to the inside of the receiving structure. The receiving structure may house calibration components such as radar lasers. The signals emitted by the calibration components (such as laser signal lights) are transmitted to the outside through the calibration hole to achieve calibration or measurement of the components to be calibrated.

[0065] Furthermore, the connecting seat 4 may be provided with a mounting structure such as a hanging rod, threaded hole, or mounting groove, which is used to install the component to be installed. Specifically, the component to be installed may be a target such as a radar calibration plate. The target may be provided with a through hole, and the signal emitted by the target can be transmitted to the component to be calibrated through the calibration hole and the through hole, thereby realizing the calibration or measurement of the component to be calibrated.

[0066] In some embodiments, the calibration bracket may further include a handrail structure disposed at one end of the slider 31, which allows the user to slide the slider 31 by pushing the handrail structure. Specifically, the handrail structure includes a first handrail that can slide or rotate at one end relative to the slider 31. The first handrail has a handrail portion at one end and a stop portion at the other end, and an elastic element is provided between the first handrail and the slider 31. The stop portion is disposed facing the crossbeam portion 1 (such as the first side wall 122, the second side wall 123, or the guide 2, etc.). If the user pushes the first handrail, the stop portion will move away from the crossbeam portion 1, and the slider 31 will unlock and slide under force. When the user releases the first handrail, the stop portion will move towards the crossbeam portion 1 under the action of the elastic element. When the stop portion abuts against the slider 31, the slider 31 will lock.

[0067] Furthermore, the handrail structure may also include a first handrail fixedly mounted on the slider 31, and a second handrail disposed opposite to the first handrail. When using the handrail, the user can simultaneously hold the first handrail and the handrail part, thereby using the first handrail for support to facilitate the user's exertion of force.

[0068] In some embodiments, a limit cap 341 is provided at one end of the connecting shaft 34 away from the fixed part 33, and a receiving groove 323 is provided at one end of the rolling element 32 away from the fixed part 33. The limit cap 341 is received in the receiving groove 323, wherein the limit cap 341 abuts against the bottom wall of the receiving groove 323, and the end of the rolling element 32 away from the crossbeam part 1 abuts against the connecting seat 4, thereby restricting the axial movement of the rolling element 32 and realizing the limiting function.

[0069] It should be noted that in order to reduce the friction between the rolling element 32 and other components, the contact area between the rolling element 32 and other components should be minimized as much as possible. Specifically, the side of the limiting cap 341 that contacts the bottom wall of the receiving groove 323 can be a conical surface, and the side of the rolling element 32 that contacts the connecting seat 4 is partially hollowed out.

[0070] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
