Description

Technical Field

[0001] This utility model belongs to the field of multi-degree-of-freedom adjustment technology, and specifically relates to a multi-degree-of-freedom rotation device. Background Technology

[0002] In existing technologies, rotating devices used to support and adjust the angles of equipment such as cameras, displays, and lamps are widely used. However, traditional rotating devices typically suffer from one or more of the following technical problems:

[0003] Limited degrees of freedom and inflexible adjustment: Many devices can only achieve rotation in one direction, which cannot meet the complex application scenarios that require simultaneous multi-angle and multi-directional adjustment; Complex structure and poor stability: In order to achieve the limiting and fixing functions, some devices use complex gears, buckles or locking mechanisms, which not only increases the complexity of the structure and manufacturing cost, but may also loosen due to wear after long-term use, affecting the stability and positioning accuracy of the equipment; Inconvenient operation and inaccurate positioning: The adjustment and locking process of some devices requires the use of tools, or the adjustment process lacks clear sense of gear positions, which leads to a poor user experience and makes it difficult to quickly and accurately fix the equipment in the preset optimal position. For example, the rotating body may "spin freely" due to the lack of effective limiting, or rely on the friction of a single component for fixing, and its reliability will be significantly reduced when subjected to vibration or impact; Functional coupling and limited performance: In some designs, the rotation support and angle limiting functions are undertaken by the same component, such as a threaded shaft. This functional coupling design makes the force transmission path unclear, which can easily lead to excessive wear of components, and may accidentally affect the state of another degree of freedom when adjusting one degree of freedom.

[0004] Therefore, based on the above problems, there is an urgent need to provide a new multi-degree-of-freedom rotation device. Utility Model Content

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0043] To achieve the above objectives, the technical solution of this utility model is as follows:

[0044] See Figures 1-7 This utility model provides a multi-degree-of-freedom rotation device, comprising:

[0045] The first mounting structure 100 includes a first body 110, the first body 110 being provided with a first mounting part 140 and a first limiting part 150;

[0046] The second mounting structure 200 includes a second body 210, a second mounting component 220, and a second rotating component 230; wherein...

[0047] The second mounting member 220 is connected to the first mounting part 140, and the second rotating member 230 is limited and engaged with the first limiting part 150.

[0048] This invention provides a multi-degree-of-freedom rotational device. The second mounting member 220 serves as the rotation axis, ensuring that the second mounting structure 200 can rotate smoothly relative to the first mounting structure 100 around the second mounting member 220. The limiting cooperation between the second rotating member 230 and the first limiting part 150 provides a limiting function during rotation, preventing the second mounting structure 200 from rotating infinitely relative to the first mounting structure 100, and fixing the rotating body, such as the second body 210 of the second mounting structure 200, at a specific preset position. That is, the limiting cooperation between the second limiting member 230 and the first limiting part 150 corresponds to a specific preset position. This multi-degree-of-freedom rotational device of this invention has a compact structure. By assigning the mounting function and the limiting function to different components, the force and motion transmission path is clear, and the structure is stable and reliable.

[0049] Furthermore, the multi-degree-of-freedom rotational device provided by this utility model also includes:

[0050] The third mounting structure 300 includes a second mounting portion 310 and a second limiting portion 320; and...

[0051] The first mounting structure 100 further includes a first mounting component 120 and a first rotating component 130; wherein...

[0052] The first mounting component 120 is connected to the second mounting part 310, and the first rotating component 130 is limited and engaged with the second limiting part 320.

[0053] By superimposing a rotary joint on the first mounting structure 100, that is, by achieving a rotary connection between the first mounting structure 100 and the third mounting structure 300, the multi-degree-of-freedom rotation device provided by this utility model has at least two rotation axes, specifically the rotation axis formed between the first mounting structure 100 and the third mounting structure 300, and the rotation axis formed between the first mounting structure 100 and the second mounting structure 200. This greatly improves the flexibility and adjustment range of the multi-degree-of-freedom rotation device. Through its multi-degree-of-freedom design, this multi-degree-of-freedom rotation device can adapt to more complex installation and adjustment scenarios, such as cameras, displays, and lamps that require simultaneous adjustment of pitch and horizontal angles.

[0054] Furthermore, the first mounting portion 140 includes a first groove 141 and a first mounting hole 142, with the first mounting hole 142 disposed in the first groove 141; the first limiting portion 150 includes a second groove 151 and a first limiting hole 152, with the first limiting hole 152 disposed at both ends of the second groove 151; wherein, the first groove 141 and the second groove 151 are connected; the second groove 151 is arc-shaped.

[0055] It should be noted that a first groove 141 and a second groove 151 are respectively formed on the side surface of the first body 110 facing the second mounting structure 200 and recessed towards the interior of the first body 110; and the second groove 151 is arc-shaped and disposed on part of the outer periphery of the first groove 141; wherein, the recess depth of the second groove 151 relative to the side surface of the first body 110 facing the second mounting structure 200 is greater than the recess depth of the first groove 141 relative to the side surface of the first body 110 facing the second mounting structure 200, that is, the second groove 151, the first groove 141 and the surface of the first body 110 sequentially form multiple steps.

[0056] Furthermore, the first mounting hole 142 is recessed from the first groove 141 toward the interior of the first body 110 and penetrates the side surface of the first body 110 away from the second mounting structure 200; preferably, the first mounting hole 142 is a threaded through hole.

[0057] Furthermore, the first limiting hole 152 is recessed from the second groove 151 toward the interior of the first body 110; preferably, the first limiting hole 152 is a blind hole; preferably, the first limiting hole 152 and the first mounting hole 142 are arranged parallel to each other and both extend along the first direction X, and the second groove 151 is arranged in an arc around the first direction X at one-quarter of the outer periphery of the first groove 141, that is, the second groove 151 is in a 90° arc shape; furthermore, the first limiting hole 152 is disposed at both ends of the second groove 151.

[0058] By setting the second groove 151 as a 90° arc-shaped groove and setting the first limiting hole 152 at both ends of the second groove 151, the sliding path of the second rotating member 230 is precisely defined, thereby limiting the rotation angle range of the second mounting structure 200 relative to the first mounting structure 100 to 0~90°, thus providing a clear rotation trajectory and fixed position.

[0059] Furthermore, the second rotating component 230 slides within the second groove 151 (i.e., the arc-shaped groove), achieving stepless adjustment. Simultaneously, the second rotating component 230 can be inserted into either of the first limiting holes 152 located at either end of the arc-shaped groove, achieving precise and fixed positioning and preventing accidental displacement of the second rotating component 230 due to external force or vibration. This design, combining the second groove 151 as a slide rail and the first limiting holes 152 as positioning holes, balances flexibility and stability, achieving compatibility between continuous adjustment and discrete positioning.

[0060] Furthermore, the second mounting member 220 penetrates the second mounting structure 200 and connects to the first mounting hole 142; one end of the second rotating member 230 is connected to the second mounting structure 200, and the other end cooperates with the first limiting part 150. Preferably, the second mounting member 220 penetrates the second body 210 from the side away from the first mounting structure 100 and connects to the first mounting hole 142 of the first body 110. Since the first mounting hole 142 is a threaded through hole and the second mounting member 220 is a threaded rod, the second mounting member 220 penetrates the second body 210 and is threadedly fastened to the first mounting hole 142 of the first body 110, thereby achieving a fastened connection or a detachable connection between the second body 210 and the first body 110.

[0061] Furthermore, the end of the second rotating member 230 away from the second mounting structure 200 is slidably engaged with the second groove 151 or can be inserted into the first limiting hole 152; the second rotating member 230 is an elastic member. Specifically, the second rotating member 230 is fixedly connected to the second body 210; the second rotating member 230 and the second mounting member 220 are spaced apart, and the distance between the second rotating member 230 and the second mounting member 220 is equal to the distance between the first limiting hole 152 and the first mounting hole 142, so as to ensure that the second rotating member 230 can slide smoothly in the second groove 151, and the second rotating member 230 can be inserted into the first limiting hole 152, wherein the second rotating member 230 is an elastic member.

[0062] Furthermore, the second mounting structure 200 also includes a second gasket 240, the second mounting member 220 passing through the second gasket 240 and connected to the first mounting hole 142, and the second gasket 240 being disposed between the first groove 141 and the second mounting structure 200. Specifically, the second gasket 240 is spaced between the side surface of the second body 210 facing the first groove 141 and the first groove 141, and the second gasket 240 is disposed within the first groove 141. Preferably, the depth dimension of the first groove 141 is greater than or equal to the thickness dimension of the second gasket 240, so that the second body 210 and the first body 110 can fit tightly together.

[0063] Preferably, the second washer 240 is a metal washer. The second washer 240 is disposed between the rotational contact surfaces formed by the first mounting structure 100 and the second mounting structure 200, thereby effectively reducing frictional resistance and wear during rotation, extending the service life of the multi-degree-of-freedom rotating device, reducing frictional wear, and improving rotational smoothness. The second washer 240 can fill assembly gaps, preventing connecting parts such as the second mounting part 220 from loosening due to vibration after long-term use, ensuring that the rotating joint always maintains appropriate preload, preventing loosening, and improving stability.

[0064] In this embodiment, the key design feature is that the second rotating member 230 is an elastic element, such as a spring pin. The user can apply a pulling force to disengage the second rotating member 230 from the first limiting hole 152 for rotational adjustment; after release, the elastic force will automatically engage the second rotating member 230 in another first limiting hole 152 for fixation. This process requires no tools and is simple, fast, and efficient. In the locked state between the second mounting structure 200 and the first mounting structure 100, the pre-tightening force of the second rotating member 230 (i.e., the elastic element) ensures a tight fit between the second rotating member 230 and the first limiting hole 152, providing a robust connection and enhanced resistance to impact and vibration.

[0065] Furthermore, the second mounting portion 310 includes a second mounting hole, and the second limiting portion 320 includes a second limiting hole; wherein the second limiting holes are circumferentially spaced apart from the second mounting hole.

[0066] With multiple second limiting holes circumferentially distributed in the second mounting hole, the first mounting structure 100 can be fixed relative to the third mounting structure 300 at multiple discrete angles within a 360° range; this effectively provides a wider angle adjustment range than the second groove 151, i.e., the arc-shaped groove, whose angle adjustment range is less than 180°, thus enabling multi-angle adjustment of the first mounting structure 100 relative to the third mounting structure 300. The circumferential distribution of the second limiting holes in the second limiting part 320 ensures that the rotating body, i.e., the first mounting structure 100 or the third mounting structure 300, receives balanced support at each fixed angle.

[0067] Furthermore, the second limiting holes of the second limiting part 320 are evenly distributed circumferentially on the outside of the second mounting hole of the second mounting part 310. The design of four second limiting holes arranged in a circumferential array on the outer periphery of the second mounting hole achieves structural symmetry and uniform force distribution.

[0068] Furthermore, the first mounting member 120 penetrates the first mounting structure 100 and is connected to the second mounting hole;

[0069] One end of the first rotating component 130 is connected to the first mounting structure 100, and the other end is engaged with the second limiting hole;

[0070] It should be added that the third mounting structure 300 includes a third body 301, and a second mounting part 310 and a second limiting part 320 are disposed on the third body 301. The third body 301 extends in the third direction Z.

[0071] The first rotating member 130 is an elastic member. Preferably, the first mounting member 120 is a threaded rod, and the second mounting hole of the second mounting part 320 is a threaded hole. The first mounting member 120 is threadedly connected to the second mounting hole to realize the connection between the second body 210 and the third body 301, that is, a fastening connection or a detachable connection.

[0072] Furthermore, the end of the first rotating member 130 away from the first mounting structure 100 is used for insertion and removal into the second limiting hole. The first rotating member 130 is fixedly connected to the first body 110.

[0073] By utilizing the elastic properties of the first rotating component 130, the rotary joint can be quickly, tool-free, and multi-anglely adjusted and locked, achieving convenient adjustment and secure locking of another degree of freedom.

[0074] Furthermore, a third groove 170 is formed by recessing the surface of the first body 110 toward the third body 301 toward the interior of the first body 110. The first body 110 is also provided with a first through hole 180 and a first blind hole 190. The first through hole 180 is formed by recessing the third groove 170 toward the side of the first body 110 away from the third body 301 and penetrates the first body 110. The first blind hole 190 is formed by recessing the third groove 170 toward the interior of the first body 110. The first blind hole 190 and the first through hole 180 are spaced apart, and both the first blind hole 190 and the first through hole 180 extend along the second direction Y.

[0075] Furthermore, the first mounting structure 100 also includes a first gasket 160, through which the first mounting member 120 passes and is connected to the second mounting hole 311. The first gasket 160 is disposed between the first mounting structure 100 and the third mounting structure 300. Specifically, the first gasket 160 is spaced between the surface of the first body 110 facing the third body 301 and the third groove 170. The first gasket 160 is disposed within the third groove 170. Preferably, the depth of the third groove 170 is greater than or equal to the thickness of the first gasket 160, so that the first body 110 and the third body 301 can fit tightly together.

[0076] Preferably, the first washer 160 is a metal washer. The first washer 160 is disposed between the rotational contact surfaces formed by the first mounting structure 100 and the third mounting structure 300, thereby effectively reducing frictional resistance and wear during rotation, extending the service life of the multi-degree-of-freedom rotating device, reducing frictional wear, and improving rotational smoothness. The first washer 160 can fill assembly gaps, preventing connectors such as the first mounting member 120 from loosening due to vibration after long-term use, ensuring that the rotating joint always maintains appropriate preload, preventing loosening, and improving stability.

[0077] Furthermore, the second mounting structure 200 is provided with a mounting groove 250 for mounting the bracket 251.

[0078] The mounting slot 250 provides a standardized interface for easy connection of various brackets 251, allowing the multi-degree-of-freedom rotation device provided in this application to be quickly installed on different devices such as cameras, surveillance probes, and mobile phones, greatly expanding the application range of the multi-degree-of-freedom rotation device and enhancing its versatility and integration convenience.

[0079] Therefore, in the multi-degree-of-freedom rotation device provided in this application, the third mounting structure 300 is assembled with the first mounting structure 100 along the third direction Z, and the first mounting structure 100 is assembled with the second mounting structure 200 along the first direction X. Using the second mounting member 220 as the rotation axis, it is ensured that the second mounting structure 200 can rotate smoothly around the second mounting member 220 and around the first direction X. The cooperation between the second rotating member 230 and the first limiting part 150 provides a limiting function during rotation, preventing the structure from spinning without limit and fixing the second rotating member 230 in a specific preset position. This multi-degree-of-freedom rotation device has a compact structure, with the mounting and limiting functions handled by different components, resulting in a clear force and motion transmission path and a stable and reliable structure.

[0080] The above are merely preferred embodiments of the present utility model and are 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.
