Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1 to 4, fig. 1 is a schematic structural diagram of an embodiment of the angle adjustable device of the present application, fig. 2 is a schematic structural diagram of a cross-section of the angle adjustable device of fig. 1 along a plane a-a, fig. 3 is an enlarged schematic diagram of a position B in fig. 2, and fig. 4 is an exploded structural diagram of the angle adjustable device of fig. 1. The angle adjustable device is any device capable of adjusting the angle, for example, a camera arranged on the intelligent wearable device, and when the angle of the camera relative to the intelligent wearable device needs to be adjusted, the angle of the camera can be directly adjusted by a user without any auxiliary tool. Specifically, the angularly adjustable device 100 includes a housing 110, a dampening bar 120, and a dampening wheel 130.

The housing 110 has an accommodating space 111 and a through hole 112 communicating with the accommodating space 111, the accommodating space 111 communicates with an external space of the angle-adjustable device 100 through the through hole 112, wherein the housing 110 of the angle-adjustable device 100 is further connected with other elements (not shown), when a user needs to adjust the angle of the angle-adjustable device 100, an external force is directly applied to the housing 110, so that the angles of the housing 110 and the connecting elements thereof are changed together. The damping rod 120 is inserted into the accommodating space 111 through the through hole 112, and has one end disposed in the accommodating space 111 and one end exposed to the outside of the case 110. The damping rod 120 specifically includes a rod body 121 and an arc-shaped protrusion 122, the rod body 121 includes a first end 1211 and a second end 1212 that are disposed opposite to each other, the arc-shaped protrusion 122 is connected to the first end 1211 of the rod body 121, when the damping rod 120 is inserted into the accommodating space 111, the first end 1211 and the arc-shaped protrusion 122 of the rod body 121 are disposed in the accommodating space 111, and the second end 1212 is exposed outside the housing 110. The damping wheel 130 is disposed in the accommodating space 111 and slidably sleeved on the periphery of the rod body 121, and when an external force is applied to the damping wheel 130, the damping wheel 130 can slide along the rod body 121, wherein at least a portion of the damping wheel 130 is tightly attached to the inner wall of the housing 110 under any state.

After the housing 110 is adjusted to a predetermined angle by applying an external force, at least a portion of one side of the arc protrusion 122 away from the rod 121 is tightly attached to the inner wall of the housing 110 to generate a first damping, at least a portion of the outer wall of the damping wheel 130 is tightly attached to the inner wall of the housing 110 to generate a second damping, and the housing 110 is maintained at the predetermined angle by the cooperation of the first damping and the second damping. Specifically, after the casing 110 is adjusted to a predetermined angle, at least a portion of the arc-shaped protrusion 122 is tightly attached to the inner wall of the casing 110 to generate a friction force, which is a first damping, at least a portion of the outer wall of the damping wheel 130 is tightly attached to the inner wall of the casing 110 to generate a friction force, which is a second damping, and the mutual fit between the first damping and the second damping can be balanced with the gravity of the casing 110 and the elements connected thereto, so that the casing 110 can be maintained at the predetermined angle. When the angle of the casing 110 needs to be changed, because the damping wheel 130 is slidably sleeved on the periphery of the damping rod 120, a user can apply an external acting force on the casing 110, so that the casing 110 drives the damping wheel 130 to move relative to the damping rod 120 along the extending direction of the damping rod 120, so that the arc-shaped convex portion 122 is separated from the inner wall of the casing 110, at this time, the first damping disappears, and the user continues to apply the external acting force, and the external acting force applied on the casing 110 is greater than the second damping between the damping wheel 130 and the casing 110, and when the external acting force applied on the casing 110 is greater than the second damping between the damping wheel 130 and the casing 110, the angle of the casing 110 relative to the damping rod 120 can be changed, specifically, because the damping rod 120 and the damping wheel 130 are both provided in the present embodiment, when the external acting force applied on the casing 110 is greater than the second damping, according to the stress situation, the housing 110 can rotate 360 degrees relative to the damping rod 120, and can also tilt a certain angle relative to the damping rod 120. As shown in fig. 2, if the coordinate system shown in fig. 2 is established (X-axis is parallel to the a-a section, Y-axis is perpendicular to the a-a section, and Z-axis is parallel to the extending direction of the rod 121), after the acting force is applied to separate the inner wall of the housing 110 from the arc-shaped protrusion 122, if the acting force continuously applied is greater than the second damping between the damping wheel 130 and the housing 110, the housing 110 may rotate 360 degrees around the Z-axis, or adjust the angle on the X/Y-axis, or both rotate 360 degrees around the Z-axis and adjust the angle on the X/Y-axis, depending on the force.

When the housing 110 is adjusted to a predetermined angle, the user directly removes the external force applied to the housing 110, and the inner wall of the housing 110 is again engaged with at least a portion of the arc protrusion 122 under the self-weight to generate a first damping, and since the damping wheel 130 is at least partially engaged with the inner wall of the housing 110 under any state, that is, the second damping is always present, the housing 110 is finally maintained at the adjusted predetermined angle under the mutual engagement of the first damping and the second damping.

As can be seen from the above, the angle-adjustable device 100 of the present embodiment can allow a user to adjust the angle directly without any auxiliary tool and without locking by a locking element such as a screw, and is convenient and fast, and on the other hand, the housing 110 of the angle-adjustable device 100 can rotate 360 degrees around the damping rod 120 and can tilt a certain angle relative to the damping rod 120.

In one application scenario, the damping rod 120 is mushroom-shaped, including a rod body 121 as a mushroom rod and an arc-shaped protrusion 122 as a mushroom head. Wherein, in order to ensure the uniformity of the stress, the damping rods 120 are in an axisymmetric pattern. And in this application scenario, in order to increase the first damping between the arc-shaped protrusion 122 and the housing 110 and the second damping between the damping wheel 130 and the housing 110, the angularly adjustable device 100 further comprises a spring 140. The spring 140 is elastically supported between the arc protrusion 122 and the damper wheel 130, and has one end 141 abutting against one side of the arc protrusion 122 close to the rod 121 and the other end 142 abutting against the damper wheel 130. Wherein the spring 140 is always in a compressed state regardless of whether the housing 110 is being angularly adjusted or the housing 110 is being held at a predetermined angle. After the casing 110 is adjusted to a predetermined angle, at this time, not only friction force but also acting force exerted by the spring 140 are provided between the arc-shaped convex part 122 and the casing 110, and not only friction force but also acting force exerted by the spring 140 are provided between the damping wheel 130 and the casing 110, compared with the case where the spring 140 is not provided, the first damping is increased, the second damping is increased, so that the gravity balance between the casing 110 and the connecting elements thereof can be ensured through the cooperation of the first damping and the second damping, and the angle change of the casing 110 under the condition of not receiving external acting force is avoided. It is understood that the amount of deformation of the spring 140 is greater than the amount of deformation of the spring 140 when the housing 110 is maintained at the predetermined angle during the application of the external force to move the housing 110 with the damping wheel 130 relative to the damping lever 120.

In this application scenario, the inner wall of the damping wheel 130 is partially attached to the rod 121, and a predetermined distance is formed between the inner wall and the rod 121, so that the spring 140 abutting against the other end 142 of the damping wheel 130 can be disposed between the damping wheel 130 and the rod 121. Of course, in other application scenarios, the inner wall of the damping wheel 130 may also be completely attached to the rod body 121, which is not limited herein.

In another application scenario, in order to increase the second damping between the damping wheel 130 and the housing 110, the angle-adjustable device 100 further includes a silicone ring 150, the silicone ring 150 surrounds the damping wheel 130 and is embedded at the periphery of the damping wheel 130, wherein when the housing 110 is maintained at the predetermined angle, at least a portion of the silicone ring 150 is tightly attached to the inner wall of the housing 110. Specifically, the damping wheel 130 is provided at the periphery thereof with an annular groove 131, the silicone ring 150 is partially disposed in the annular groove 131 and partially protrudes out of the annular groove 131, and when the housing 110 is held at a predetermined angle, the portion of the silicone ring 150 protruding out of the annular groove 131 is pressed by the housing 110 and the damping wheel 130 to be closely attached to the inner wall of the housing 110, thereby increasing the frictional force between the damping wheel 130 and the housing 110. The number of the silicone rings 150 can be set according to specific conditions, and the number of the silicone rings can be one, two or more, which is not limited herein. It should be noted that the silicone ring 150 may also be fixed on the periphery of the damping wheel 130 by an adhesive, such as glue, a double-sided tape, and the like.

Similarly, a silicon sheet (not shown) may be disposed on a side of the arc protrusion 122 away from the rod body 121, and a friction force between the arc protrusion 122 and the shell 110 is increased by the silicon sheet, so that the shell 110 is not easily moved relative to the damping rod 120 without being affected by an external force.

In another application scenario, the housing 110 includes a first housing 1101 and a second housing 1102, the first housing 1101 and the second housing 1102 are detachably connected, for example, by bolts, threads, snaps, and the like, and the first housing 1101 and the second housing 1102 cooperate with each other to form the accommodating space 111, and when the housing 110 is held at a predetermined angle, at least a portion of the arc protrusion 122 closely fits to an inner wall of the first housing 1101, and at least a portion of the damping wheel 130 closely fits to an inner wall of the second housing 1102.

In another application scenario, the angle-adjustable device 100 further includes a base 160 for supporting the angle-adjustable device 100, which is fixedly connected to the second end 1212 of the rod body 121 of the damping rod 120. While the base 160 also serves to secure the angularly adjustable device 100 to other devices.

The material of the damping rod 120 and the damping wheel 130 is not limited in this application, and may be metal, silica gel, or other materials.

To facilitate understanding of the angle-adjustable device 100 in the present application, the following describes the adjustment process of the angle-adjustable device 100 in detail with reference to fig. 1 to 4 again.

When the angle of the housing 110 does not need to be changed, at least part of the arc-shaped convex part 122 is attached to the inner wall of the first housing 1101 to generate a first damping, at least part of the damping wheel 130 is attached to the inner wall of the second housing 1102 to generate a second damping, so that the first damping and the second damping are mutually matched to balance the gravity of the housing 110, and the housing 110 is static relative to the damping rod 120 and the damping wheel 130.

When the angle of the housing 110 needs to be adjusted, a user applies an external force to move the housing 110 along the extending direction of the damping rod 120 to a direction close to the arc-shaped protrusion 122, and the damping wheel 130 moves together with the housing 110 relative to the damping rod 120 under the driving of the housing 110. When the housing 110 moves relative to the damping rod 120 to separate the arc-shaped protrusion 122 from the first housing 1101, the first damping between the arc-shaped protrusion 122 and the first housing 1101 disappears, and the user can continue to apply a force to make the applied force greater than the second damping between the damping wheel 130 and the second housing 1102, so as to make the housing 110 perform 360-degree rotation around the damping rod 120 and/or tilt at a certain angle relative to the damping rod 120, where it should be noted that the 360-degree rotation of the housing 110 around the damping rod 120 and the tilting of the housing 110 relative to the damping rod 120 may be performed independently or simultaneously, that is, the housing 110 may perform only 360-degree rotation around the damping rod 120, or the housing 110 may tilt at a certain angle relative to the damping rod 120, or the housing 110 may tilt at the same time as performing 360-degree rotation around the damping rod 120 and also tilt at the same time relative to the damping rod 120.

After the casing 110 is adjusted to a predetermined angle, the user removes the external force applied to the casing 110, at this time, under the action of the self weight, the inner wall of the first casing 1101 is attached to the arc-shaped protrusion 122 again, that is, the first damping is generated again, because at least part of the damping wheel 130 is always attached to the inner wall of the second casing 1102 in the adjusting process, that is, the second damping is always present, and the casing 110 is finally maintained at the predetermined angle under the mutual cooperation of the first damping and the second damping.

The silicone ring 240 surrounds the damping wheel 220 and is embedded on the periphery of the damping wheel 220.

The damping rod 210, the damping wheel 220, the spring 230, and the silicone ring 240 in this embodiment are the same as the damping rod 120, the damping wheel 130, the spring 140, and the silicone ring 150 in the above embodiments, and the detailed structure can be referred to the above embodiments, which is not described herein again.

In summary, the angle-adjustable device in the present application is provided with the damping rod and the damping wheel slidably sleeved on the periphery of the damping rod, so that when the housing is adjusted to a predetermined angle, a first damping is generated between the arc-shaped convex portion of the damping rod and the housing, and a second damping is generated between the damping wheel and the housing, so that the housing is maintained at the predetermined angle through the mutual cooperation of the first damping and the second damping, and the user can directly adjust the angle of the housing, which is convenient to operate.
