[0038] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0039] The steps described in the specification and the flowcharts in the accompanying drawings of this invention are not necessarily to be strictly followed according to the step numbers; the execution order of the steps can be changed. Furthermore, certain steps can be omitted, multiple steps can be combined into one step, and / or one step can be broken down into multiple steps.

[0040] The development of optoelectronic equipment requires mounting it on a vehicle roof and driving along a specific route. During this journey, the equipment needs to be rotated to test its performance. Current methods involve disassembling the equipment, lifting it, rotating it at a certain angle, and then reinstalling it. However, since the vehicle and equipment are usually already connected for power and signal transmission, lifting and rotating the equipment poses a risk of power and signal interruption. Furthermore, optoelectronic equipment is typically heavy and complex to install, requiring two or more people to operate it. The operating space on the vehicle roof is also limited, making it difficult to rotate the equipment after disassembly. Finally, performing complex operations in a confined space on the vehicle roof also presents certain dangers.

[0041] In order to overcome the shortcomings of the prior art, the present invention provides a vehicle rotation device 100 for testing various optoelectronic devices 510. It can quickly rotate the optoelectronic device 510 to a certain angle. It is simple to operate and highly safe. It is especially suitable for devices with limited operating size and those that cannot be disassembled or installed in environments such as the roof of a vehicle.

[0042] According to an embodiment of the present invention, a vehicle rotation device 100 is used to fix a photoelectric device 510 to the top of the vehicle and to adjust the rotation angle of the photoelectric device 510, such as... Figures 1-7 As shown, the indexing device 100 includes: a fixed plate 10, a rotating assembly 20, and a support rod 30.

[0043] Among them, combined Figure 4 and Figure 5 As shown, the fixing plate 10 is fixed to the roof 600 of the vehicle. The rotating assembly 20 is located on the side of the fixing plate 10 away from the roof 600, and the photoelectric device 510 is provided on the rotating assembly 20. For example, when the fixing plate 10 is fixed to the roof 600, the rotating assembly 20 is located above the fixing plate 10.

[0044] One end of the support rod 30 can pass through the rotating assembly 20 and abut against the fixed plate 10, so that the rotating assembly 20 and the fixed plate 10 are separated. The rotating assembly 20 can rotate relative to the fixed plate 10 under the support of the support rod 30 and the fixed plate 10, so as to adjust the rotation angle of the photoelectric device 510.

[0045] It should be noted that since the rotating component 20 and the fixed plate 10 are in surface-to-surface contact, it is difficult and inconvenient to directly make relative rotation between the rotating component 20 and the fixed plate 10. By using the support rod 30, the rotating component 20 can be separated from the fixed plate 10, and the surface-to-surface contact between the rotating component 20 and the fixed plate 10 can be converted into a point-to-surface contact between the support rod 30 and the fixed plate 10, thereby facilitating the rotational adjustment between the rotating component 20 and the fixed plate 10.

[0046] Combination Figure 6 and Figure 7 As shown, the vehicle rotation device 100 according to an embodiment of the present invention, when performing rotation operation, only the rotation device 100 needs to be rotated, without disassembling the photoelectric device 510, thus ensuring the stability of power supply and signal transmission of the photoelectric device 510; the present invention utilizes the rotation device 100 to convert surface friction into point friction, which is simple to operate and can be performed by a single person; the present invention has low requirements for operating space and is suitable for confined spaces; the present invention utilizes the rotation device 100, which eliminates the need for large-scale operations, resulting in high operational safety; the present invention is particularly suitable for scenarios with small operating spaces and high operating heights.

[0047] According to some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the rotating component 20 has a through mating hole with an internal thread, and the support rod 30 has an external thread 330 that matches the internal thread. That is, the rotating component 20 and the support rod 30 can be threaded together. When the support rod 30 is rotated, it can be screwed in or out, thereby controlling the support rod 30 to make the rotating component 20 fit or separate from the fixed plate 10, so as to control the rotation of the rotating component 20.

[0048] In some embodiments of the present invention, such as Figures 1-4 As shown, the rotating assembly 20 includes a rotating plate 210 and a flange 220. The photoelectric device 510 is disposed on the rotating plate 210. The flange 220 is disposed on the rotating plate 210, and the rotating plate 210 has a through hole that is opposite to the through hole of the flange 220. The mating hole includes a through hole and a through hole, and an internal thread is provided on the inner wall of the through hole.

[0049] It should be noted that the rotating assembly 20 can also consist of only a rotating plate 210, with a mating hole having internal threads to mate with the external threads 330 of the support rod 30. It is understandable that by using a flange 220 and its through-hole internal threads, the thickness requirement of the rotating plate 210 can be reduced compared to directly creating a mating hole with internal threads in the rotating plate 210.

[0050] According to some embodiments of the present invention, such as Figure 3 and Figure 4As shown, the end of the support rod 30 facing the fixed plate 10 is a ball head 310, and the fixed plate 10 is provided with a spherical surface 110 that matches the ball head 310. It can be understood that by setting the ball head 310 and the spherical surface 110, when rotating, the support rod 30 and the spherical surface 110 at the center of the fixed plate 10 come into contact, converting the surface friction between the rotating component 20 and the fixed plate 10 into point friction. This can reduce the frictional force between the support rod 30 and the fixed plate 10 during rotation, and facilitate the relative rotation between the rotating component 20 and the fixed plate 10.

[0051] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, a handle 320 is provided at the end of the support rod 30 away from the fixed plate 10. It can be understood that by providing the handle 320, the support rod 30 can be easily rotated.

[0052] According to some embodiments of the present invention, such as Figure 4 As shown, the handle 320 is a circular rotary steering wheel with radial stripes. The rotary steering wheel may also be provided with an axially extending grip, thereby improving the ease of operation of the handle 320 and making it more convenient for personnel to operate.

[0053] In some embodiments of the present invention, such as Figure 4 As shown, the rotation device 100 further includes a fixing member 40, which cooperates with the rotating assembly 20 and the fixing plate 10 to fix the rotating assembly 20 and the fixing plate 10 after the photoelectric device 510 rotates to a preset angle. This prevents relative movement between the rotating assembly 20 and the fixing plate 10 support, improving the reliability of fixing the photoelectric device 510.

[0054] According to some embodiments of the present invention, such as Figures 1-4 As shown, the rotating component 20 has an arc-shaped groove 211 with the support rod 30 passing through the point as the center, and the fixing plate 10 has a plurality of fixing holes 120 spaced apart with the point where the support rod 30 abuts as the center. When the photoelectric device 510 rotates to a preset angle, the fixing member 40 passes through the groove 211 and cooperates with the fixing holes 120 to fix the rotating component 20 and the fixing plate 10.

[0055] For example, the fastener 40 can be a bolt that passes through the slide groove 211 and fits into the fixing hole 120. When it is necessary to adjust the angle of the photoelectric device 510, the bolt can be loosened, the rotating component 20 can be rotated to the preset angle, and then the bolt can be tightened to fix it, which is convenient and efficient.

[0056] In some embodiments of the present invention, such as Figure 5As shown, the indexing device 100 is fixed to the roof 600 via the roof mounting bracket 610. This facilitates the fixed assembly of the indexing device 100 and avoids the problem of having to drill too many holes in the roof 600 if the indexing device 100 is directly fixed to the roof 600.

[0057] According to some embodiments of the present invention, such as Figure 5 As shown, the rotating assembly 20 is also provided with a photoelectric load 520, and the support rod 30 is located between the photoelectric device 510 and the photoelectric load 520. It can be understood that placing the support rod 30 between the photoelectric device 510 and the photoelectric load 520 can effectively utilize the area of ​​the indexing device 100 and improve the compactness of the indexing device 100.

[0058] The present invention will now be described in detail with reference to the accompanying drawings, taking the indexing device 100 mounted on a sports car as an example. It should be understood that the following description is merely exemplary and should not be construed as a specific limitation of the present invention.

[0059] like Figure 1 As shown, the sports car quick-shifting device 100 includes: a support rod 30, a rotating assembly 20, and a fixing plate 10.

[0060] like Figure 1 As shown, the support rod 30 can be screwed into the flange 220 of the rotating assembly 20, and the flange 220 is fixed to the rotating plate 210 in the rotating assembly 20. The rotating assembly 20 is fixed to the fixed plate 10 by mounting bolts (i.e., the fastener 40 mentioned above).

[0061] like Figures 2-4 As shown, the support rod 30 is provided with a ball head 310 and an external thread 330, the rotating plate 210 is provided with a sliding groove 211, and the fixed plate 10 is provided with a spherical surface 110 at its center.

[0062] like Figure 5 As shown, a roof mounting bracket 610 is installed on the roof 600, and the rotation device 100 is fixed to the roof mounting bracket 610 by a fixing plate 10. A photoelectric device 510 and a photoelectric load 520 are installed on the rotating plate 210.

[0063] Working principle:

[0064] like Figures 1-7 As shown, the sports car rapid rotation device 100 of the present invention adopts a support rod 30 + rotating component 20 + fixing plate 10, which has a simple structure, low cost, stable and mature process, and long service life.

[0065] In use, the rotating support rod 30 is screwed into the flange 220 of the rotating assembly 20 via its external thread 330, thus separating the rotating assembly 20 from the fixed plate 10. The ball head 310 of the support rod 30 and the spherical surface 110 of the fixed plate 10 make point contact. When the rotating assembly 20 is rotated, the surface friction between the rotating assembly 20 and the fixed plate 10 is converted into point friction between the ball head 310 of the support rod 30 and the spherical surface 110 of the fixed plate 10. The frictional force is reduced, and the trolley quick-rotation device 100 can easily rotate the photoelectric device 510 and the photoelectric load 520 fixed on the rotating plate 210. After rotation, the rotating assembly 20 is fixed to the fixed plate 10 by using mounting bolts through the sliding groove 211 on the rotating plate 210, thereby achieving quick rotation.

[0066] In summary, the vehicle rotation device 100 of this invention allows for simple rotation of the vehicle track quick rotation device 100 during rotation operations, eliminating the need to disassemble the photoelectric device 510 and ensuring the stability of power supply and signal transmission for the photoelectric device 510. This invention utilizes the vehicle track quick rotation device 100 to convert surface friction into point friction, simplifying operation and allowing for single-person operation. It requires minimal operating space and is suitable for confined spaces. The vehicle track quick rotation device 100 eliminates the need for large-scale operations, ensuring high operational safety. This invention is particularly suitable for scenarios with limited operating space and high operating heights.

[0067] Through the description of specific embodiments, a more in-depth and specific understanding should be gained of the technical means and effects adopted by the present invention to achieve the intended purpose. However, the accompanying drawings are only for reference and illustration and are not intended to limit the present invention.
