Conventional rotating platform is all based on the rotating platform that central axis is built currently on the market.Since the central axis occupies The central area of the routine rotating platform, limited installation space is separated into annular space, leads to other components or each Kind functional module (such as laser radar or camera module etc. sensor) can only be fixed around the central axis, because This, under the trend of product miniaturization multifunction, which will greatly limit the installation of various functional modules, cause to produce Product size is not able to satisfy the demand of miniaturization, and ideal effect is not achieved.Further, since the central area of the rotating platform is by this Mandrel occupies, and causes various sensors that can only be eccentrically mounted on the rotating platform, so that entire product is relative in this The rotary inertia of mandrel is unevenly distributed, and therefore, which will occur biggish bounce or shake, serious shadow when rotated The normal work or service life of the rotating platform are rung, and then also will affect perception or the detection accuracy of various functional modules.

With reference to shown in Fig. 1 to Fig. 5 of attached drawing, the hidden shaft type rotating device of the one of a preferred embodiment according to the present utility model And manufacturing method is elucidated with.It is traditional to substitute by a hidden axis mechanism in the preferred embodiment of the utility model The central axle designs of rotating platform, so that the central area of the hidden shaft type rotating device can be used in installing various function moulds Block, and the rotation function of the hidden shaft type rotating device is not influenced, be conducive to the overall volume for reducing complete product, Jin Erman The demand of sufficient product miniaturization trend.

Specifically, as depicted in figs. 1 and 2, the hidden shaft type rotating device 10 includes a base assembly 11, a rotary components 12, a driving mechanism 13 and a hidden axis mechanism 15.The driving mechanism 13 is arranged at the base assembly 11 and the rotation Turn between component 12, to drive the rotary components 12 around a center of the rotary components 12 by the driving mechanism 13 Axis 120 rotates.The rotary components 12 have a central area 121 and a fringe region 122, wherein the fringe region 122 are located at around the central area 121, and the central axis 120 passes through the center of the rotary components 12 Region 121.The hidden axis mechanism 15 is fixedly arranged on the fringe region 122 of the rotary components 12, in the hidden axis machine A complete installation space 150 is formed between structure 15 and the central area 121 of the rotary components 12, for by a function mould Block 20 is installed on the central area 121 of the rotary components 12.When the rotary components 12 are driven by the driving mechanism 13 When moving with around the central axis 120 rotation, the rotary components 12 are for driving the functional module 20 around the center Axis 120 carries out 360 degree rotation, and the functional module 20 is enabled to perceive or detect in all directions ambient enviroment.This field Technical staff it is understood that the functional module 20 can be, but not limited to be implemented as such as laser radar, camera module, Thermal imaging inductor etc. can orient perception or detect the sensor of external environment, to acquire ring by the functional module 20 Border data, wherein the environmental data can be obstacle distance information, traffic information, itself posture information etc., this is practical It is novel without limitation.

Further, as shown in Fig. 2, the hidden shaft type rotating device 10 further includes a cap assembly 14, wherein the top Cap assemblies 14 are arranged in correspondence in the base assembly 11, with the shape between the cap assembly 14 and the base assembly 11 At an accommodation space 100, to accommodate the rotary components 12, the driving mechanism 13, the hidden axis mechanism 15 and be mounted In the functional module 20 of the rotary components 12.In addition, one end of the hidden axis mechanism 15 and the rotary components 12 The fringe region 122 is permanently connected, and the other end of the hidden axis mechanism 15 is that axis quilt can with the central axis 120 It is rotationally connected with the cap assembly 14, the hidden axis mechanism 15 is enabled to substitute the central axis of conventional rotating platform, To ensure that the overall mechanism of the hidden shaft type rotating device 10 is stablized.

It is worth noting that, when the rotary components 12 are driven by the driving mechanism 13 around the central axis When 120 rotation, the hidden axis mechanism 15 is driven by the rotary components 12 to rotate around the central axis 120, so that institute It states hidden axis mechanism 15 and is substituting the central axis in conventional rotating platform to ensure hidden 10 stable structure of shaft type rotating device Meanwhile the central area 121 of the rotary components 12 will not be also occupied or separate, so that the functional module 20 is installed To the central area 121 of the rotary components 12, facilitate the overall dimensions for reducing the hidden shaft type rotating device 10.It changes Sentence is talked about, since the hidden axis mechanism 15 is fixedly arranged on the fringe region 122 of the rotary components 12, rather than conventional rotation The central axis for turning platform will occupy the center of rotating platform like that, therefore the hidden shaft type rotating device 10 can be in the hidden axis machine The central area 121 of structure 15 and the rotary components 12 forms a complete installation space, is convenient for the functional module 20 are integrally mounted to the central area 121 of the rotary components 12, to reduce the whole of the hidden shaft type rotary components 12 Body size, it helps replace the functional module 20.

Further, since the functional module 20 can be installed in the central area 121 of the rotary components 12, and The central axis 120 of the rotary components 12 passes through the central area 121 of the rotary components 12, therefore, described The center of gravity that functional module 20 can be configured to the functional module 20 is located at the central axis 120, so that the function The rotary inertia of module 20 is minimum, therefore when the rotary components 12 drive the functional module 20 around the central axis When 120 rotation, the centrifugal force that the functional module 20 is subject to is minimum, to prevent damaging the functional module because centrifugal force is excessive 20, facilitate the service life for extending the functional module 20.

In this way, without the concern for the type or weight of the functional module 20, only being needed when installing the functional module 20 Ensure that the center of gravity of the functional module 20 is located at the central axis 120 of the rotary components 12, so that the hidden axis Formula rotating device 10 can adapt to the functional module 20 of various types or different weight.It should be appreciated that for routine Rotating platform cause functional module that can only prejudicially be pacified since central axis is in occupation of the central area of conventional rotating platform Loaded on conventional rotating platform, need to carry out dynamic balancing detection and calibration to the conventional rotating platform for being equipped with functional module, therefore The routine rotating platform can only adapt to the functional module of specific dimensions and weight, that is to say, that once replacement different type or not With the functional module of weight, then the dynamic balancing of the routine rotating platform can be seriously destroyed, cause the routine rotating platform can not be just Often work.

More specifically, the hidden axis mechanism 15 includes at least two brackets 151 and a top frame 152, wherein the top frame 152 are connect in a manner of bearing connection with the cap assembly 14, and per the bracket 151 from the institute of the rotary components 12 It states fringe region 122 and extends to the top frame 152, to rotatably support the cap assembly by the hidden axis mechanism 15 14, convenient for while enhancing the overall structural strength of the hidden shaft type rotating device 10, also using the hidden axis mechanism 15 come The central axis of conventional rotating platform is substituted, to enhance the rotational stability of the rotary components 12.
