[0040] The implementation process of the technical solution of the present invention is described below in conjunction with specific embodiments, which is not intended to limit the present invention.

[0041] The present invention proposes a rotating measuring unit connected to the outside through a support shaft, and the rotating measuring unit is a measuring device with a rotating scanning mechanism. The present invention records the core architecture of the rotating measuring unit, and based on the core architecture and improved to obtain a variety of practical applications, multiple types of measuring equipment are realized, such as lidar or other optical, laser, and radio measuring devices, but not limited thereto. The rotating measuring unit connected to the outside through a support shaft based on the present invention can be more suitable for the use environment, help optimize the design and installation, and improve the use efficiency. It is also convenient for equipment weight reduction and volume compression.

[0042] like Figure 2 , 3A 3B is a schematic diagram of the structure of a single rotating measuring machine connected to the outside through a support shaft of the present invention.

[0043] The rotation measuring unit 1 connected to the outside through the support shaft comprises:

[0044] Support shaft 10;

[0045] The rotating unit 20 is disposed on the supporting shaft 10;

[0046] A non-rotating unit 30 is disposed on the support shaft 10;

[0047] A housing 40 is disposed on the support shaft 10 and covers the support shaft 10, the rotating unit 20 and the non-rotating unit 30;

[0048] The support shaft 10 is also used to be connected to an external structural member 50 outside the rotation measuring unit 1 to support the rotation measuring unit 1 .

[0049] The rotating unit 20 can be coupled to the support shaft 10 through a connecting component such as a bearing. The rotating unit 20 can rotate relative to the support shaft 10. The non-rotating unit 30 is stationary relative to the support shaft 10. The housing 40 only serves as isolation protection and has no supporting and positioning function.

[0050] The architecture designed by the present invention eliminates the existing design method that takes the inherent base as the core, and transforms it into a design method that takes the support shaft 10 as the core, and uses the support shaft 10 as the basis for internal positioning and support and the root component that carries all components. It also serves as a hub for external connection and support. The architecture designed by the present invention has an integrated design concept, with the support shaft 10 as the main focus, providing a stable, reliable, and simple architecture foundation for design modifications, installation position changes, and installation form adjustments during product development, thereby greatly improving the robustness of the overall architecture.

[0051] Specifically, the present invention provides a new support and positioning architecture. Internally, all components in the rotating measuring unit 1 are mounted on the support shaft 10, and externally, the support shaft 10 is rigidly connected to the external structural member. That is, the architecture design of the present invention is centralized. The support shaft 10 is the core of the structure, and all components are placed on the support shaft 10. The position of the rotating measuring unit 1 can be changed by changing the position of the support shaft 10, and the connection with the rotating measuring unit 1 can be achieved by connecting with the support shaft 10. It can be seen that the present invention abandons the prior art of taking the base as the reference and changes to taking the support shaft as the reference, so that the position or shape setting of the support shaft can be accurately transmitted to all components of the rotating measuring unit 1 through the support shaft, thereby improving the overall design planning controllability of all components in the rotating measuring unit 1.

[0052] The external structural member may be a load-bearing substrate on a smart car body, or a load-bearing bracket of a drone, but is not limited thereto. The rotation measurement unit 1 is connected or separated with the external structural member through the support shaft 10 to meet different practical needs in a real environment.

[0053] In one embodiment, the end of the support shaft 10 has an external rigid connection interface 15. Through the external rigid connection interface 15, it can be connected to an external structural member, thereby realizing the positioning connection between the rotation measurement unit and the external structural member. For example, the external rigid connection interface 15 can be a screw hole, and a screw is inserted into the screw hole to connect and position the rotation measurement unit 1 to an external structural member to achieve a rigid connection. The specific method of the external rigid connection interface 15 may include a variety of obvious variations, all of which are within the scope of the disclosure of the present invention.

[0054] The end of the support shaft has a reliable positioning portion 16, which is used to achieve reliable positioning of the support shaft 10 and the housing. Figure 3B As shown, the cross section of the reliable positioning portion 16 can be larger than the cross section of the support shaft 10 and be circular or rectangular, or the reliable positioning portion 16 can also be cross-shaped. Various obvious deformations of the reliable positioning portion 16 are also within the scope of the disclosure of the present invention. The reliable positioning portion 16 and the external rigid connection interface 15 can be provided simultaneously or selectively. The support shaft 10 can be connected to the external structural member only through one end thereof, or can be connected to the corresponding external structural member through both ends, such as Figure 4A That is to say, the rotary measuring unit 1 can be fixed at two positioning points to increase the fixing firmness and stability. The two ends of the support shaft 10 can be connected to the corresponding external structural parts respectively, so that the rotary measuring unit can be flexibly fixed and connected in various practical application environments.

[0055] In addition, one or both ends of the support shaft 10 may protrude from the housing 40, such as Figure 4BAt this time, the support shaft 10 can be inserted into the positioning groove of the external structural member to achieve a rigid connection with the external structural member. In addition, since the support shaft 10 protrudes from the housing 40, the support shaft 10 can be inserted into the corresponding external structural member at a desired predetermined angle, such as Figure 4C As shown, the support shaft 10 and the housing 40 can be connected at a desired angle.

[0056] Inserting the support shaft 10 into the external structural member at a required angle can further improve the convenience of assembly, so that the installation angle can be more conveniently adapted to the objective environmental requirements.

[0057] That is, by adjusting the connection angle between the support shaft 10 and the external structural member, the installation and debugging of the relative position of the rotating unit 20 and the external structural member can be made more accurate. In particular, when the rotating measurement unit is placed on a vehicle body or an intelligent robot, especially in situations where the installation position requirements are relatively strict, the overall structural setting method of the laser radar of the present invention will be more advantageous.

[0058] Similarly, a reliable positioning portion 16 can be provided at the end of the support shaft 10 to achieve reliable positioning of the support shaft 10 and the external structural member. Various obvious variations of the reliable positioning portion 16 are also within the scope of the present invention.

[0059] In another embodiment, if Figure 5A , 5B As shown, the support shaft can be in a broken line shape, including a first support portion 11 and a second support portion 12, the first support portion and the second support portion are connected end to end or are separately arranged. The first support portion 11 and the second support portion 12 have different angles relative to a reference plane A. The rotating unit 20 includes a first rotating unit 21 and a second rotating unit 22, the first rotating unit 21 is arranged on the first supporting portion 11, and the second rotating unit 22 is arranged on the second supporting portion 12.

[0060] At this time, the first support portion 11 and the second support portion 12 are respectively connected to different external structural members. In another embodiment, the first support portion 11 and the second support portion 12 can also be connected to the same external structural member 50, such as Figure 6 shown.

[0061] The housing 40 can be a fully enclosed opaque material suitable for forming a magnetic detection device. In addition, the housing 40 can also have a light-transmitting area or a wave-transmitting area, for example, the housing 40 can have an optical window to facilitate the transmission and reception of laser and optical signals.

[0062] The housing 40 is provided with an external electrical connection interface, including electronic and electrical components, and the external electrical connection interface can be connected to the non-rotating unit.

[0063] The housing 40 and the support shaft 10 are designed separately. The housing 40 and the support shaft 10 can be made of different materials. The housing 40 can be tightly clamped on the surface of the support shaft 10, or tightly engaged with the support shaft in other ways, so as not to loosen. And because the housing does not bear any positioning support function, the shape of the housing can be based on the space occupied by its internal components, so that the housing has greater design flexibility, and the shape can be adaptively adjusted according to the space requirements, and the volume can be compressed. The material selection of the housing does not need to be dense, and light weight is the basis.

[0064] The rotating unit 20 includes: a laser measurement sensor, an image measurement sensor, a radar measurement unit, and / or a rotating structure.

[0065] The non-rotating unit 30 includes: a driving / control circuit, a data processing circuit, and / or a non-rotating structural component.

[0066] By selecting the specific composition of the rotating unit 20 and the non-rotating unit 30, the rotating measuring unit can be configured for different types of specific applications.

[0067] For example, when the rotation unit 20 includes at least a laser measurement sensor, the rotation measurement unit 1 may form a laser radar connected to the outside through a support shaft.

[0068] When the rotation unit 20 includes an image measurement sensor, the rotation measurement unit 1 can form an image detection device.

[0069] When the rotation unit 20 comprises a radar measurement unit, the rotation measurement unit 1 can form a detection device.

[0070] The non-rotating unit 30 can be configured to have circuits or structural components that are required according to the specific application being formed.

[0071] The structural design of the present invention that is connected to the outside through the support shaft is transformed into a design with the support shaft 10 as the core, and the support shaft 10 is used as the basis for internal positioning and support and the root component for carrying all components. It also serves as a hub for external connection and support. This makes the structure designed by the present invention have an integrated design concept, eliminating the design method of the prior art that takes the base as the core.

[0072] The present invention uses the support shaft 10 as the main gripper, the rotating unit 20 is uniquely bound to the support shaft 10, and the positioning or position and angle adjustment of the rotating unit 20 only needs to be performed on the support shaft 10. This makes the laser radar more suitable for the use environment and improves the use efficiency.

[0073] At the same time, the rotating unit 20 is only structurally related to the supporting shaft 10, which improves the modular functional partitioning of the laser radar and can enrich the peripheral adaptability design of the laser radar to adapt to various usage environments.

[0074] The support shaft 10 simultaneously supports the rotating unit 20 inside the laser radar and positions the external structural parts, so that the core internal component of the laser radar, that is, the rotating unit 20, can be accurately positioned relative to the external components.

[0075] The support shaft 10 can be inserted into the corresponding external structural member according to a predetermined angle, so that the architecture of the present invention has a more flexible customization space. It provides a stable, reliable and simple architecture foundation for design modification, installation position change and installation form adjustment during product development, greatly improving the robustness of the overall architecture.

[0076] The above embodiments are merely exemplary descriptions for implementing the present invention and are not intended to limit the protection scope of the present invention. Those skilled in the art may make various obvious modifications and equivalent replacement technical solutions based on the above embodiments, which are all included in the disclosure scope of the present invention. The protection scope of the present invention shall be subject to the following claims.
