Description

Technical Field

[0001] This invention relates to the field of camera technology, and more particularly to a pan-tilt head and a pan-tilt camera. Background Technology

[0002] A gimbal is typically used to fix and support equipment such as cameras and to adjust the shooting direction of the equipment.

[0003] When installing a pan-tilt head upside down, to improve its reliability and prevent the risk of it falling due to loose screws, the pan-tilt head structure generally includes a base, housing, gears, and pins. Pins are typically used to connect the gears and the base. However, limiting and securing the pins is quite difficult, thus increasing the installation complexity of both the pan-tilt head structure and the camera. Summary of the Invention

[0004] Some embodiments of the present invention provide a pan-tilt unit and a pan-tilt camera, which makes the installation and fixing of the pivot pin more convenient, reduces the assembly difficulty of the pan-tilt unit and the pan-tilt camera, and thus improves the installation efficiency.

[0005] In a first aspect, the present invention provides a gimbal, the gimbal comprising: a base having a base body and an annular boss connected to the base body; a first hole provided on the annular boss; a housing rotatably connected to the base; a first transmission member located within the housing and having a second hole; an elastic snap-fit ​​member and a connecting member; and a slip ring located inside the annular boss; wherein the elastic snap-fit ​​member is configured as part of the hole wall of the first hole and is located at one end of the first hole near the base body; when the first end of the connecting member passes through the second hole to reach the first hole, it pushes open the elastic snap-fit ​​member, and the connecting member... After the first end of the connector passes through the first hole, the elastic snap-fit ​​member returns to its original shape and engages with the connector; or, the elastic snap-fit ​​member is configured as part of the hole wall of the second hole and is located at the end of the second hole away from the base body; when the first end of the connector passes through the first hole and reaches the second hole, the elastic snap-fit ​​member is pushed away, and after the first end of the connector passes through the second hole, the elastic snap-fit ​​member returns to its original shape and engages with the connector; the slip ring is used to abut against the elastic snap-fit ​​member when the elastic snap-fit ​​member and the connector are engaged, to prevent the elastic snap-fit ​​member from deforming.

[0006] The gimbal provided in this embodiment of the invention restricts the axial displacement of the connecting member by setting up mutually interlocking elastic locking parts and connecting parts, thereby realizing the connection between the annular boss and the first transmission member and preventing the first transmission member from falling under the action of gravity. Compared with installing a retaining spring inside the annular boss to limit and fix the pin shaft, the gimbal in this embodiment is easier to install, especially in small spaces, where its advantages are obvious. No other tools are needed, and the operator can complete the installation with one hand, reducing the assembly difficulty of the gimbal and improving the installation efficiency. On this basis, by setting up a slip ring that abuts against the elastic locking part, when the elastic locking part is subjected to external force (for example, under the action of external force, the elastic locking part may move away from the connecting part), the slip ring can block the elastic locking part and prevent it from deforming, thereby ensuring the reliability of the interlocking between the elastic locking part and the connecting part, further improving the reliability of the connection between the annular boss and the first transmission member and preventing the first transmission member from falling under the action of gravity.

[0007] In some embodiments, the elastic snap-fit ​​member includes: a deformable arm having a fixed end and a free end; and a snap-fit ​​portion disposed at the free end of the deformable arm and snap-fitted with the connector; wherein, when the elastic snap-fit ​​member is configured as part of the hole wall of the first hole, the fixed end of the deformable arm is fixedly connected to the annular boss; and when the elastic snap-fit ​​member is configured as part of the hole wall of the second hole, the fixed end of the deformable arm is fixedly connected to the first transmission member.

[0008] In some embodiments, a first groove is provided on the end face of the latch portion away from the deformable arm, and the first groove is offset from the first end of the connector.

[0009] In some embodiments, the end face of the latching portion near the deformable arm is configured as a guide surface, the guide surface being inclined, and in the horizontal direction, the side of the guide surface near the deformable arm is closer to the fixed end than the side of the guide surface away from the deformable arm.

[0010] In some embodiments, the connector is a pin.

[0011] In some embodiments, the pin includes a first sub-part and a second sub-part connected to each other; the first sub-part and the second sub-part are coaxially arranged, and the average diameter of the first sub-part is smaller than the average diameter of the second sub-part; the latching part is arranged opposite to the first sub-part, and the latching part protrudes toward the first hole.

[0012] In some embodiments, the gimbal further includes: a locking screw, wherein the first transmission member and the annular boss are fixedly connected by the locking screw; and there is a play in the axial and radial directions of the pin, so that when the locking screw falls off, the first transmission member shakes during transmission.

[0013] In some embodiments, the annular boss includes an annular inner wall and an annular outer wall, the annular outer wall surrounding the annular inner wall; the first hole is located between the annular inner wall and the annular outer wall, and is fixedly connected to both the annular inner wall and the annular outer wall; when the resilient snap-fit ​​is configured as part of the hole wall of the first hole, the resilient snap-fit ​​is also configured as part of the annular inner wall.

[0014] In some embodiments, the gimbal further includes a limiting part, which is connected to the slip ring and the base body.

[0015] In some embodiments, the gimbal further includes: at least one bearing located between the annular boss and the housing, the housing rotating relative to the annular boss via the bearing; and a second transmission member connected to the housing, the second transmission member meshing with the first transmission member, and the second transmission member moving around the first transmission member to drive the housing to rotate.

[0016] Secondly, the present invention provides a PTZ camera, the PTZ camera comprising: the PTZ as described in any of the above embodiments and a camera mounted on the PTZ.

[0017] The beneficial effects of the second aspect mentioned above can be referred to the description of the first aspect, and will not be repeated here. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] In the description of this invention, it should be understood that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings; they are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0027] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0028] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection", and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] like Figure 1 As shown, some embodiments of this application provide a PTZ camera 1000. The camera is mounted on a PTZ platform, which drives the camera to rotate, capturing images from multiple angles, thus expanding the camera's monitoring range and enabling large-area scanning and monitoring.

[0030] For example, the PTZ camera 1000 can be widely used in specific scenarios such as conference rooms. As another example, the PTZ camera 1000 can also be used as a security camera.

[0031] For example, such as Figure 1 As shown, the pan-tilt camera 1000 includes a pan-tilt unit 100 and at least one camera 200.

[0032] For example, the pan-tilt unit 100 is used to mount and fix a camera.

[0033] For example, the pan-tilt unit 100 can rotate, thereby causing the camera 200 to rotate.

[0034] In one implementation, such as Figure 2 As shown, the pan-tilt head 100 generally includes a base, a housing, a gear, and a pin 500. The pin 500 typically connects the gear and the base. For example, one end of the pin 500 passes through the mounting holes on the gear and the base sequentially from bottom to top, thus connecting the gear and the base. Since the end of the pin 500 needs to pass through the mounting holes on the gear and the base, the diameter of the end of the pin 500 must be less than or equal to the diameter of the mounting holes on the gear and the base. To prevent the pin 500 from falling under gravity and causing the connection between the gear and the base to fail, a retaining ring 3 is usually installed to limit and fix the end of the pin 500. However, due to the small internal space of the annular boss 12, the installation of the retaining ring 3 is difficult, and the size of the retaining ring 3 is usually small, requiring the use of other tools for installation, thus making the installation of the pan-tilt head 100 and the pan-tilt camera 1000 more difficult.

[0035] Based on this, some embodiments of this application provide a pan-tilt unit 100, which can be applied to the pan-tilt camera 1000 described above.

[0036] In some examples, such as Figure 3 As shown, the gimbal 100 includes: a base 10, a housing 20, a first transmission component 30, an elastic snap-fit ​​component 40, a connector 50, and a slip ring 60.

[0037] For example, when the pan-tilt head 100 is applied to the pan-tilt camera 1000, the pan-tilt head 100 can be either inverted or upright. In the inverted case, the base 10 is on top, and the housing 20 is located below the base 10. In the upright case, the housing 20 is on top, and the base 10 is located below the housing 20.

[0038] In some examples, combined Figures 3-5As shown, the base 10 has a base body 11 and an annular boss 12 connected to the base body 11, and the annular boss 12 is provided with a first hole 121.

[0039] For example, the base 10 is used to fix the gimbal 100.

[0040] Optionally, the base body 11 and the annular boss 12 can be an integral structure. The base body 11 and the annular boss 12 can be integrated in various ways, such as by integral casting, stamping, or other suitable methods; the embodiments of this application do not limit this.

[0041] It is understandable that "integrated structure" refers to the fact that the two connected components are continuous and not separated. When the base body 11 and the annular boss 12 are integrated, it not only simplifies the manufacturing process of the base 10, but also improves the structural stability of the base 10, and facilitates unified manufacturing and assembly, thus reducing assembly costs.

[0042] For example, the housing 20 is rotatably connected to the base 10. That is, the housing 20 is movable relative to the base 10.

[0043] For example, in combination Figure 3 and Figure 4 As shown, the housing 20 has an opening 21, and the annular boss 12 extends into the housing 20 through the opening 21.

[0044] For example, the camera 200 is fixedly connected to the housing 20, and the housing 20 can drive the camera 200 to rotate.

[0045] For example, the base 10 is fixed, while the housing 20 rotates, thereby causing the camera 200 to rotate and enabling the camera 200 to monitor different areas.

[0046] In some examples, combined Figure 3 and Figure 4 As shown, the first transmission component 30 is located inside the housing 20, and the first transmission component 30 has a second hole 31.

[0047] For example, the first transmission member 30 is connected to the end of the annular boss 12 away from the base body 11.

[0048] Optionally, the first transmission member 30 is fitted with the end face of the annular boss 12 on the side away from the base body 11.

[0049] For example, the first transmission member 30 and the annular boss 12 can be connected to each other in various ways. For instance, the first transmission member 30 and the annular boss 12 can be connected by plug-in connection, fastener locking connection, etc.

[0050] Optionally, the first transmission component 30 can be a gear. The gear and the annular boss 12 can be coaxially arranged.

[0051] For example, the number of flexible snap-fit ​​connectors 40 can be one or more, and the embodiments of this application do not limit this.

[0052] For example, the number of connectors 50 can be one or more, and the embodiments of this application do not limit this. It is understood that the number of connectors 50 is the same as the number of elastic snap-fit ​​connectors 40, and the connectors 50 and elastic snap-fit ​​connectors 40 are configured in a one-to-one correspondence.

[0053] For example, such as Figure 3 and Figure 4 As shown, the connector 50 has a first end 51 and a second end 52 opposite to each other.

[0054] In some examples, such as Figure 5 As shown, the aforementioned elastic snap-fit ​​member 40 is configured as part of the hole wall of the first hole 121 and is located at one end of the first hole 121 near the base body 11.

[0055] For example, during the installation of connector 50, when the first end 51 of connector 50 passes through the second hole 31 and reaches the first hole 121, the elastic snap-fit ​​member 40 is pushed open. After the first end 51 of connector 50 passes through the first hole 121, the elastic snap-fit ​​member 40 returns to its original shape and snaps into contact with connector 50. This restricts connector 50 along its axial direction (i.e., Figure 3 The displacement in the Y direction (as shown in the diagram); in addition, the second end 52 of the connector 50 abuts against the first transmission member 30, thereby limiting the displacement of the first transmission member 30 in the Y direction.

[0056] In other examples, the aforementioned resilient snap-fit ​​40 is configured as part of the hole wall of the second hole 31 and is located at the end of the second hole 31 away from the base body 11.

[0057] For example, when installing the connector 50, when the first end 51 of the connector 50 passes through the first hole 121 and reaches the second hole 31, the elastic snap-fit ​​member 40 is pushed open. After the first end 51 of the connector 50 passes through the second hole 31, the elastic snap-fit ​​member 40 returns to its original shape and snaps into the connector 50. Thus, the connection between the annular boss 12 and the first transmission member 30 is achieved through the connector 50, preventing the first transmission member 30 from falling under the action of gravity.

[0058] In some examples, combined Figure 3 and Figure 4As shown, the slip ring 60 is located inside the annular boss 12; the slip ring 60 is used to abut against the elastic snap-fit ​​member 40 when the elastic snap-fit ​​member 40 and the connector 50 are snapped together, so as to prevent the elastic snap-fit ​​member 40 from deforming.

[0059] For example, the slip ring 60 abuts against the resilient snap fastener 40, preventing the resilient snap fastener 40 from moving away from the connector 50.

[0060] For example, the slip ring 60 is hollow inside, and at least part of the cable in the gimbal 100 can pass through the interior of the slip ring 60.

[0061] The gimbal 100 provided in the embodiments of the present invention restricts the axial displacement of the connecting member 50 by setting an elastic snap-fit ​​member 40 and a connecting member 50 that interlock with each other, thereby realizing the connection between the annular boss 12 and the first transmission member 30 and preventing the first transmission member 30 from falling off under the action of gravity. Compared with installing a retaining spring 3 inside the annular boss to limit and fix the pin 500, the gimbal 100 in this embodiment is easier to install, especially when working in a small space, and has obvious advantages. No other tools are needed, and the operator can complete the installation with one hand, reducing costs. The assembly difficulty of the gimbal 100 improves installation efficiency. Furthermore, by setting a slip ring 60, which abuts against the elastic locking member 40, when the elastic locking member 40 is subjected to external force (for example, under the action of external force, the elastic locking member 40 may move away from the connector 50), the slip ring 60 can block the elastic locking member 40, preventing deformation and thus ensuring the reliability of the engagement between the elastic locking member 40 and the connector 50. This further improves the reliability of the connection between the annular boss 12 and the first transmission member 30, preventing the first transmission member 30 from falling under gravity.

[0062] In some embodiments, combined with Figure 3 and Figure 5 As shown, the elastic snap-fit ​​member 40 includes: a deformable arm 41 and a snap-fit ​​part 42.

[0063] For example, the deformable arm 41 has a fixed end and a free end. A latching part 42 is provided at the free end of the deformable arm 41 and engages with the connector 50.

[0064] For example, the deformable arm 41 can move relative to the annular boss 12 under the action of an external force.

[0065] For example, such as Figure 5As shown, the deformable arm 41 is connected to the latching part 42 and is an integral structure. When the latching part 42 moves under the action of an external force, the deformable arm 41 connected to the latching part 42 will undergo elastic deformation under the action of the latching part 42. When the external force is removed, the deformable arm 41 can return to its original position (or return to its original shape), so that the elastic latching member 40 can be used multiple times.

[0066] It should be noted that when the elastic snap-fit ​​40 is configured as part of the hole wall of the first hole 121, the fixed end of the deformable arm 41 is the end of the deformable arm 41 that is fixedly connected to the other parts of the first hole 121; the other end opposite to the fixed end of the deformable arm 41 is the free end of the deformable arm 41. That is, the fixed end of the deformable arm 41 is fixedly connected to the annular boss 12. At this time, the deformable arm 41 and the annular boss 12 can be integrated into one structure and formed using the same mold, thus eliminating the need to fix the elastic snap-fit ​​40 to the annular boss 12, and eliminating the need to install the fixing structure of the connector 40 in the narrow space of the annular boss 12, thereby reducing the difficulty of installing and fixing the connector 40 and reducing the assembly difficulty of the gimbal 100.

[0067] When the elastic snap-fit ​​member 40 is configured as part of the hole wall of the second hole 31, the fixed end of the deformable arm 41 is the end that is fixedly connected to the other part of the second hole 31, and the other end opposite to the fixed end of the deformable arm 41 is the free end of the deformable arm 41. That is, the fixed end of the deformable arm 41 is fixedly connected to the first transmission member 30. At this time, the deformable arm 41 and the first transmission member 30 can be integrated into one structure and formed using the same mold, thus eliminating the need to fix the elastic snap-fit ​​member 40 to the first transmission member 30, thereby reducing the difficulty of installing and fixing the connector 40 and reducing the assembly difficulty of the gimbal 100.

[0068] In some embodiments, combined with Figure 3 and Figure 5 As shown, a first groove 421 is provided on the end face of the buckle part 42 away from the deformable arm 41, and the first groove 421 is offset from the first end 51 of the connector 50.

[0069] For example, the depth direction of the first groove 421 is parallel to the axial direction of the elastic snap-fit ​​member 40.

[0070] When disassembling the connector 50, an external force can be applied to the elastic snap-fit ​​member 40 using the first groove 421. For example, an external force can be applied to the snap-fit ​​part 42 away from the connector 50, causing the deformable arm 41 to move away from the connector 50, thereby separating the elastic snap-fit ​​member 40 from the connector 50, and thus the connector 50 can be easily disassembled. In addition, the first groove 421 is offset from the first end 51 of the connector 50. Therefore, when disassembling the connector 50, the first end 51 can be prevented from blocking the first groove 421, so that the first groove 421 is exposed outside the first end 51. This allows the first groove 421 to be used to apply external force to the snap-fit ​​part 42, thereby disassembling the connector 50.

[0071] In some embodiments, combined with Figure 3 and Figure 5 As shown, the end face of the latching part 42 near the deformable arm 41 is configured as a guide surface. The guide surface is inclined, and in the horizontal direction, the side of the guide surface near the deformable arm 41 is closer to the fixed end than the side of the guide surface away from the deformable arm 41.

[0072] For example, the latching portion 42 also includes a first surface that abuts against the connector 50. The first surface is connected to the aforementioned guide surface.

[0073] For example, in the end face of the latching part 42 near the deformable arm 41, a portion of the end face is configured as a guide surface, and the remaining portion of the end face is used for fixed connection with the deformable arm; in the horizontal direction, the side of the guide surface near the deformable arm 41 is in direct contact with the deformable arm 41, and the side of the guide surface away from the deformable arm 41 is in direct contact with the aforementioned first surface.

[0074] For example, during the insertion of the connector 50, under the action of external force, the first end 51 of the connector 50 first contacts the guide surface of the latching part 42, and then under the action of external force, the connector 50 pushes away the guide surface and continues to move forward until the connector 50 is engaged with the latching part 42.

[0075] It is understandable that when the first end 51 of the connector 50 contacts the guide surface of the latching part 42 and the connector 50 continues to move forward, the latching part 42, under the action of the external force, causes the deformable arm 41 to undergo elastic deformation. When the external force is removed, the deformable arm 41 can return to its original position.

[0076] With the above configuration, the installation of the connector 50 is more convenient. Under the action of external force, the first end 51 of the connector 50 can more easily pass over the latching part 42 and then engage with the latching part 42.

[0077] In some embodiments, the connector 50 is a pin 500.

[0078] For example, multiple pins 500 are symmetrically arranged about the center line of the annular boss 12. This further improves the reliability of the connection between the annular boss 12 and the first transmission member 30.

[0079] Using pin 500 as a connector ensures reliable operation and easy disassembly. Compared with conventional connectors, pin 500 has higher strength and lower cost, which helps reduce the manufacturing cost of gimbal 100.

[0080] In some embodiments, such as Figure 4 As shown, the pin 500 includes a first sub-part 501 and a second sub-part 502 that are connected to each other. The first sub-part 501 and the second sub-part 502 are coaxially arranged, and the average diameter of the first sub-part 501 is smaller than the average diameter of the second sub-part 502.

[0081] For example, the first end 51 of the connector 50 (that is, the first end 51 of the pin 500) is connected to the first sub-part 501; the second end 52 of the connector 50 (that is, the second end 52 of the pin 500) is connected to the second sub-part 502.

[0082] Furthermore, the diameter of the first end 51 of the connector 50 (i.e., the first end 51 of the pin 500) is larger than the average diameter of the first sub-part 501, and the diameter of the second end 52 of the connector 50 (i.e., the second end 52 of the pin 500) is larger than the average diameter of the second sub-part 502. Thus, the axial movement of the pin 500 and the connection and fixation between the annular boss 12 and the first transmission member 30 can be restricted by the first end 51 and the second end 52.

[0083] For example, the first end 51, the first sub-part 501, the second sub-part 502, and the second end 52 can be an integral structure. The first end 51, the first sub-part 501, the second sub-part 502, and the second end 52 can be configured as an integral structure in various ways, such as integral casting, stamping, or other suitable methods, thereby facilitating the machining of the pin 500 and the overall installation.

[0084] For example, after the pin 500 is installed, the first sub-part 501 and the second sub-part 502 are located inside the first hole 121 and the second hole 31. The first end 51 of the connector 50 (that is, the first end 51 of the pin 500) and the second end 52 of the connector 50 (that is, the second end 52 of the pin 500) are located outside the first hole 121 and the second hole 31.

[0085] For example, the latching part 42 is disposed opposite to the first sub-part 501, and the latching part 42 protrudes toward the first hole 121.

[0086] For example, the latching part 42 abuts against the first sub-part 501, which prevents the pin 500 from moving along its axial direction and avoids the pin 500 from falling off under its own weight. Furthermore, the pin 500 is used to connect and fix the annular boss 12 to the first transmission member 30.

[0087] In some embodiments, such as Figure 4 As shown, the gimbal 100 also includes at least one locking screw 70, and the first transmission member 30 is fixedly connected to the annular boss 12 by at least one locking screw 70.

[0088] In some examples, the first transmission member 30 is fixedly connected to the annular boss 12 by a single locking screw 70. In other examples, the first transmission member 30 is fixedly connected to the annular boss 12 by multiple locking screws 70. Embodiments of the present invention are not limited in this respect.

[0089] Furthermore, when the first transmission member 30 and the annular boss 12 are fixedly connected by a plurality of locking screws 70, the positions of the plurality of locking screws 70 can be symmetrically arranged about the center of the first transmission member 30. This further improves the reliability of the connection between the annular boss 12 and the first transmission member 30.

[0090] Optionally, the locking screw 70 can be a self-tapping screw or a regular screw. The embodiments of this application do not limit this.

[0091] For example, the first transmission member 30 is provided with at least one through hole, and correspondingly, the annular boss 12 is provided with a screw hole on its end face near the first transmission member 30. When assembling the gimbal 100, the locking screw 70 passes through the through hole on the first transmission member 30 and connects to the screw hole on the annular boss 12 from the side of the first transmission member 30 away from the annular boss 12, thereby achieving a fixed connection between the first transmission member 30 and the annular boss 12.

[0092] In some examples, there is play in both the axial and radial directions of the pin 500 so that the first transmission member 30 wobbles during transmission when the locking screw 70 falls off.

[0093] For example, the average diameter of the first sub-part 501 and the average diameter of the second sub-part 502 of the pin 500 are both smaller than the diameters of the first hole 121 and the second hole 31, resulting in a clearance in the radial direction of the pin 500. The axial length of the pin 500 is greater than the maximum distance between the first hole 121 and the second hole 31, resulting in a clearance in the axial direction of the pin 500.

[0094] Based on this, when the gimbal 100 is inverted, the base 10 is on top, and the housing 20 is below the base 10. The weight of the housing 20 and the structures on the housing 20 (such as the camera 200) is borne by the first transmission member 30. When the locking screw 70 falls off, under the action of gravity, the first transmission member 30, the housing 20, and the structures on the housing 20 may fall, potentially causing a safety accident. In the embodiments of this application, the elastic snap-fit ​​member 40 snaps into the pin 500, restricting the displacement of the first transmission member 30 in the Y direction, thus achieving a dual connection between the annular boss 12 and the first transmission member 30. At this time, even if the locking screw 70 loosens or falls off, the first transmission component 30 can still be hooked onto the base 10 through the elastic snap-fit ​​40 and the pin 500. Under the action of gravity, the first transmission component 30, the housing 20 and the structure on the housing 20 may fall down, but will not completely fall off, thus preventing the first transmission component 30, the housing 20 and the structure on the housing 20 from falling off. At the same time, due to the existence of the axial and radial movement clearance of the pin 500, the first transmission component 30 will shake during transmission, resulting in abnormal transmission. This allows the operator to discover the abnormality and repair it in time, thereby further avoiding damage caused by the first transmission component 30 falling off.

[0095] In some embodiments, combined with Figure 3 and Figure 5 As shown, the annular boss 12 includes an annular inner wall 122 and an annular outer wall 123. The annular outer wall 123 surrounds the annular inner wall 122.

[0096] For example, the first hole 121 is located between the inner annular wall 122 and the outer annular wall 123, and the hole wall of the first hole 121 is fixedly connected to both the inner annular wall 122 and the outer annular wall 123.

[0097] For example, when the resilient snap-fit ​​40 is configured as part of the hole wall of the first hole 121, the resilient snap-fit ​​40 is also configured as part of the annular inner wall 122.

[0098] For example, the first hole 121, the annular inner wall 122, and the annular outer wall 123 are integral structures formed using the same mold. The elastic snap-fit ​​member 40 is located at the connection position between the first hole 121 and the annular inner wall 122.

[0099] For example, in the hole wall of the first hole 121, the hole wall near the end of the first transmission member 30 is a complete hole wall, and the hole wall away from the first transmission member 30 is a non-complete hole wall. A portion of this hole wall constitutes the aforementioned elastic snap-fit ​​member 40. Furthermore, the elastic snap-fit ​​member 40 is also configured as part of the annular inner wall 122, where the hole wall near the end of the annular inner wall 122 near the first transmission member 30 is a complete hole wall, and the hole wall away from the end of the annular inner wall 122 is a non-complete hole wall. A portion of this hole wall constitutes the aforementioned elastic snap-fit ​​member 40.

[0100] Therefore, the axial positioning of the pin 500 can be achieved by engaging the elastic snap-fit ​​part 40 with the pin 500, and the entire structure of the gimbal 100 is made simpler and easier to assemble.

[0101] In some embodiments, such as Figure 4 As shown, the gimbal 100 also includes a limiting part 80, which is connected to the slip ring 60 and the base body 11.

[0102] For example, the limiting part 80 and the slip ring 60 can be an integral structure.

[0103] For example, the limiting part 80 and the base body 11 can be interconnected by at least one locking screw 70.

[0104] In some examples, the limiting part 80 is fixedly connected to the base body 11 by a locking screw 70. In other examples, the limiting part 80 is fixedly connected to the base body 11 by multiple locking screws 70. Embodiments of the present invention do not limit this.

[0105] Furthermore, when the limiting part 80 and the base body 11 are fixedly connected by a plurality of locking screws 70, the positions of the plurality of locking screws 70 can be symmetrically arranged about the center of the limiting part 80. This further improves the reliability of the connection between the annular boss 12 and the first transmission member 30.

[0106] In some embodiments, such as Figure 4 As shown, the gimbal 100 also includes at least one bearing 90, which is located between the annular boss 12 and the housing 20, and the housing 20 rotates relative to the annular boss 12 via the bearing 90.

[0107] For example, the bearing 90 is capable of rotating around the annular boss 12.

[0108] For example, the number of bearings 90 can be one or more, and the embodiments of this application do not limit this. Figure 4 The diagram shows two bearings at 90°.

[0109] Optionally, the bearing 90 may include an inner ring, an outer ring, and a rotor disposed coaxially between the inner and outer rings. The inner ring of the bearing 90 is fitted onto the annular boss 12, and the outer ring of the bearing 90 is connected to the inner wall of the housing 20 near the annular boss 12.

[0110] For example, the gimbal 100 further includes a second transmission member, which is connected to the housing 20 and engages with the first transmission member 30. The second transmission member moves around the first transmission member 30, thereby causing the housing 20 to rotate.

[0111] Optionally, the second transmission component can be a gear.

[0112] Optionally, the gimbal 100 may also include a motor disposed inside the housing 20. The output shaft of the motor is connected to a second transmission member, providing driving force to the second transmission member, enabling the second transmission member to move around the first transmission member 30.

[0113] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
