Smart wearable devices (e.g., smart watches, smart bracelets, smart glasses, etc.) are becoming increasingly popular with consumers, wherein smart watches are particularly widely focused by consumers, and compared with other smart wearable devices, smart watches are not only small and portable, but also can meet the demands of consumers on functions, such as conversation, voice, video, etc., to the greatest extent. However, as the requirements of users on the shooting angles of the cameras of the smart watches are higher and higher, more and more smart watches are designed to be reversible so as to achieve the effect of adjusting shooting at more angles.

In the prior art, the reversible intelligent watch is characterized in that the bearing plate and the turnover shaft are increased, so that the intelligent host can turn around the turnover shaft relative to the bearing plate, meanwhile, the rotation shaft is further increased, the extending direction of the rotation shaft is perpendicular to the extending direction of the turnover shaft, and after the intelligent host turns around the rotation shaft to form a certain angle relative to the bearing plate, the intelligent host can rotate around the rotation shaft, so that the purpose of intelligent watch multi-angle shooting is achieved. Although the purpose that the intelligent host rotates along different directions is achieved by arranging the turning shaft and the rotating shaft, the complexity of a connecting structure between the intelligent host and the bearing plate is also improved.

In view of this, the embodiment of the invention provides an intelligent wearable device, which can realize the purpose that the main body rotates in different directions without arranging a plurality of rotating shafts, and simplifies the connection structure between the main body and the bearing plate.

The following describes the smart wearable device in detail through specific embodiments:

example 1

The embodiment of the application provides an intelligent wearable device 100, as shown in fig. 1, the intelligent wearable device 100 includes a bearing plate 130, a host body 110 and a ball head rotating shaft 120. Referring to fig. 4, the edge of the host body 110 is provided with a spherical groove 111, the ball-head rotating shaft 120 is disposed between the bearing plate 130 and the host body 110, the ball-head rotating shaft 120 includes a shaft portion 122 and a ball-head portion 121 disposed at one end of the shaft portion 122, the shaft portion 122 is connected to the bearing plate 130, the ball-head portion 121 is cooperatively connected with the spherical groove 111 to form a spherical pair, and the spherical pair is configured to: the main body 110 can be turned in a direction approaching or separating from the carrier plate 130, and the main body 110 can be rotated around the shaft 122.

It should be noted that, the carrying board 130 is a board body for carrying the host computer body 110 in the intelligent wearable apparatus 100, the length of the board surface of the carrying board 130 should be greater than or equal to the length of the host computer body 110, and the width of the board surface of the carrying board 130 should be greater than or equal to the width of the host computer body 110.

As shown in fig. 1, 2 and 4, the ball-end rotating shaft 120 is disposed between the bearing plate 130 and the host body 110, so that the host body 110 is connected to the bearing plate 130 through the ball-end rotating shaft 120, specifically, the shaft portion 122 of the ball-end rotating shaft 120 is fixedly connected to the bearing plate 130, and the ball-end portion 121 is matched with a spherical groove in the host body 110.

The spherical groove 111 is a groove whose inner wall is spherical, and the inner wall of the spherical groove 111 corresponds to the surface of the ball head 121, so that a spherical pair can be formed when the surface of the ball head 121 is matched with the inner wall of the spherical groove 111.

As can be seen from the above description, since the spherical pair is formed by the mating connection of the spherical portion 121 and the spherical groove 111, and the rotating shaft is fixedly arranged on the bearing plate 130, the host body 110 can rotate on the bearing plate 130 relative to the shaft portion 122 through the spherical pair, and can turn over in a direction approaching or separating from the bearing plate 130 through the spherical pair, so that the host body 110 can rotate along different directions without arranging a plurality of rotating shafts, and the connection structure between the host body 110 and the bearing plate 130 is simplified.

It should be further noted that, as shown in fig. 1, the host body 110 turning in a direction approaching or separating from the carrier plate 130 means that the host body 110 turns in a first preset direction (X direction), and when the host body 110 turns in the first preset direction relative to the ball pivot 120, the angle between the host body 110 and the carrier plate 130 is changed. The rotation of the main body 110 relative to the shaft 122 at the middle of the edge of the carrier 130 means that the main body 110 rotates along the second preset direction (Y direction) at the middle of the edge of the carrier 130, and when the main body 110 rotates relative to the ball rotating shaft 120 along the second preset direction, the included angle between the main body 110 and the carrier 130 remains unchanged. In addition, the first preset direction and the second preset direction are perpendicular to each other.

In addition, the main body 110 may first turn along a first preset direction and then rotate along a second preset direction relative to the ball pivot 120, and the main body 110 may also first rotate along the second preset direction and then turn along the first preset direction relative to the ball pivot 120, which is not limited herein. For example, when a user takes a picture by using the smart wearable device 100, the host body 110 is first turned 90 ° along a first preset direction, as shown in fig. 5, and then the host body 110 is adjusted to rotate 90 ° along a second preset direction, as shown in fig. 6, so that the smart wearable device 100 is at an optimal photographing angle. Wherein, the overturning angle of the main body 110 relative to the ball head rotating shaft 120 along the first preset direction is between 0 and 180 degrees, and the rotating angle of the main body 110 relative to the ball head rotating shaft 120 along the second preset direction is between 0 and 360 degrees.

In some embodiments, as shown in fig. 3 and 4, the ball groove 111 is disposed in the middle of the edge of the host body 110.

The middle of the edge refers to the middle position or the position near the middle of the edge of either side of the main body 110. Thus, the main body 110 can be rotated around the central portion of the edge of the main body 110 with respect to the ball pivot 120.

In order to achieve the purpose of turning the main body 110 along the first preset direction relative to the ball pivot 120, in some embodiments, as shown in fig. 3 and 4, a through hole 113 and a first guide groove 112 are formed on the lower surface of the main body 110, which are communicated with the spherical groove 111, the first guide groove 112 is connected with the through hole 113, and the first guide groove 112 penetrates through the side wall of the main body 110, which is close to one side of the spherical groove 111, and the diameter of the through hole 113 and the width of the first guide groove 112 are smaller than the diameter of the ball 121, and the shaft 122 can pass through the first guide groove 112 to turn the main body 110 along the preset direction.

It should be understood that the above-mentioned preset directions include a first preset direction and a second preset direction.

In this embodiment, as shown in fig. 2, when the main body 110 is fully attached to the carrier 130, the shaft 122 is fixedly connected to the ball 121 located in the ball groove 111 through the through hole 113, and as shown in fig. 3 and 5, when the main body 110 is turned over in the first preset direction relative to the ball pivot 120, the main body 110 is changed from being connected to the shaft 122 through the through hole 113 to being connected to the shaft 122 through the first guide groove 112, that is, when the main body 110 is turned over in the direction away from the carrier 130, the shaft 122 enters the first guide groove 112 through the through hole 113, and as the main body 110 continues to move in the direction away from the carrier 130, the shaft 122 continues to move in the first guide groove 112 until the shaft 122 abuts against the side wall of the first guide groove 112. Thus, by providing the first guide groove 112 connected with the through hole 113, the interference between the main body 110 and the shaft 122 during the overturning process along the first preset direction is avoided, so that the main body 110 can be overturned smoothly along the first preset direction relative to the ball rotating shaft 120.

In another embodiment, as shown in fig. 7, 8 and 14, a spherical groove 111 is provided at a corner of the main body 110.

Thus, the main body 110 can also be rotated in a third preset direction (Z direction) by the spherical pair, wherein the third preset direction is perpendicular to the first preset direction and the second preset direction, respectively, and the main body 110 has a first sidewall 1181 and a second sidewall 1182 adjacent and perpendicular, and the corner is near the intersection position of the first sidewall 1181 and the second sidewall 1182. For example, when the host body 110 is turned by 90 ° along the first preset direction, the first sidewall 1181 abuts against the carrying plate 130, and when the host body 110 is rotated by 90 ° along the third preset direction, the host body 110 is converted from abutting against the carrying plate 130 through the first sidewall 1181 to abutting against the second sidewall 1182 to abutting against the carrying plate 130, thereby realizing the switching between the horizontal screen and the vertical screen of the host body 110.

Specifically, as shown in fig. 10, the lower surface of the main body 110 is provided with a through hole 113, a first guide groove 112 and a second guide groove 119, which are communicated with the spherical groove 111, the first guide groove 112 and the second guide groove 119 are respectively connected with the through hole 113, the first guide groove 112 penetrates through a first sidewall 1181 of the main body 110 on a side close to the spherical groove 111, the second guide groove 119 penetrates through a second sidewall 1182 of the main body 110 on a side close to the spherical groove 111, the first sidewall 1181 and the second sidewall 1182 are mutually perpendicular and adjacent, the diameter of the through hole 113, the width of the first guide groove 112 and the width of the second guide groove 119 are smaller than the diameter of the ball head 121, and the shaft 122 can turn over the main body 110 along different preset directions through the first guide groove 112 and the second guide groove 119.

In this embodiment, when the main body 110 is turned over along the first preset direction relative to the ball pivot 120, the first guiding groove 112 guides the shaft 122, so that the main body 110 moves in a direction approaching or separating from the bearing plate 130, and different angles are formed between the main body 110 and the bearing plate 130. Similarly, when the main body 110 rotates along the third preset direction relative to the ball pivot 120, the second guiding groove 119 guides the shaft 122, so that the main body 110 is transformed from the first sidewall 1181 abutting against the bearing plate 130 to the second sidewall 1182 abutting against the bearing plate 130, thereby realizing the switching between the horizontal screen and the vertical screen of the main body 110.

The shaft 122 is fixedly disposed in the middle or corner of the edge of the carrier 130, and the shaft 122 is fixedly connected to the carrier 130 in various manners, wherein one possible connection manner is as follows: the shaft 122 and the bearing plate 130 are adhered and fixed, namely, an adhesive layer is coated between the connection parts of the shaft 122 and the bearing plate 130, and the shaft 122 and the bearing plate 130 are fixed together after the adhesive layer is solidified, so that the installation is convenient.

In another possible connection manner, the shaft portion 122 is fixedly connected with the bearing plate 130 through threads, specifically, the shaft portion 122 has external threads, a threaded hole is formed in the middle of the edge of the bearing plate 130, and the shaft portion 122 is connected with the threaded hole in a matched manner through the external threads, so that the shaft portion 122 and the bearing plate 130 are fixedly connected, and connection stability of the shaft portion 122 and the bearing plate 130 is improved. The threaded hole may be a through hole 113 or a blind hole, which is not limited herein.

Of course, the manner of the fixed connection between the shaft 122 and the bearing plate 130 is not limited to the above two types, and will not be described in detail herein.

The smart wearable device 100, such as a camera of a smart watch, is disposed on the host body 110, and when a video call or photographing is performed by using the smart watch, the camera needs to be adjusted to achieve multi-angle photographing, that is, the position of the host body 110 relative to the carrier plate 130 is adjusted, so that a user can take a photograph or perform a video call in a more comfortable posture. Specifically, the main body 110 is rotated along the first preset direction and/or the second preset direction by the ball pivot 120, so that the camera can shoot at multiple angles, however, because the main body 110 has a certain bearing force, in the process of shooting at multiple angles by adjusting the main body 110, the camera is easy to shake, so that the shooting stability of the camera is poor, thereby affecting the user experience, and based on this, in some embodiments, as shown in fig. 11, the main body 110 is further provided with a damping member 150, and the damping member 150 is used for providing a damping force for keeping the main body 110 in a rotated state, so that the main body 110 can keep the rotated state for a long time.

The damping member 150 is provided with a plurality of types, for example, the damping member 150 includes a plurality of layers of elastic pieces which are stacked, the plurality of layers of elastic pieces are located above the ball head portion 121 and are abutted to the ball head portion 121, an end face of one end of each of the plurality of layers of elastic pieces, which is abutted to the ball head portion 121, is an arc surface corresponding to the spherical surface of the ball head portion 121, and the plurality of layers of elastic pieces are in a pre-tightening state, so that the pre-tightening force of the plurality of layers of elastic pieces generates longitudinal pressure on the ball head portion 121, a friction damping force is generated between the ball head portion 121 and the arc surface, and the friction damping force can enable the main body 110 to keep the state after rotation. For another example, the damping member 150 is an elastic member, the elastic member is in a pre-tensioned state, and a friction damping force is provided between the end of the elastic member abutting against the ball head portion 121 and the ball head portion 121. The following description will be made in detail with the damping member 150 as an elastic member:

in one possible embodiment, as shown in fig. 4 and 11, the accommodating cavity 114 communicating with the spherical groove 111 is provided in the main body 110, the damping member 150 includes an elastic member disposed in the accommodating cavity 114, one end of the elastic member abuts against a top wall of the accommodating cavity 114, the other end of the elastic member abuts against the ball head 121, and the elastic member can apply pressure to the ball head 121 to form a friction damping force between the ball head 121 and the spherical groove 111.

In this embodiment, the elastic member is installed in the accommodating chamber 114 in a pre-tensioned state, and one end of the elastic member is abutted against the top wall of the accommodating chamber 114, and the other end of the elastic member is abutted against the ball head 121, whereby the elastic member can apply pressure to the ball head 121, so that a frictional damping force is formed between the ball head 121 and the spherical groove 111, which can maintain the main body 110 in its rotated state.

In addition, the pressure applied to the ball portion 121 by the elastic member can be transmitted to the ball portion 121 through the ball portion 121, that is, the ball portion 121 applies pressure to the ball portion 111, and thus, a friction damping force is also formed between the ball portion 121 and the ball portion 111, so that the friction damping force acting on the ball portion 121 is increased, the damping effect of the damping member 150 is improved, and the stability of the state maintained after the rotation of the main body 110 is further improved.

The specific structure of the elastic member is various, and in one possible embodiment, the elastic member may be a rubber column, and the end surface of the rubber column, which is used for abutting against the ball head 121, is a concave spherical surface, and the concave spherical surface is matched with the ball head 121.

In this embodiment, since the concave spherical surface is abutted against the ball head 121 and the rubber column can apply pressure to the ball head 121, a frictional damping force is formed between the concave spherical surface and the ball head 121. Because the end surface of the rubber column, which is used for being abutted against the ball head 121, is a concave spherical surface, the contact area between the rubber column and the ball head 121 is increased, so that the friction damping force between the concave spherical surface and the ball head 121 is increased, and the damping effect of the damping piece 150 is further improved.

The concave spherical surface is a spherical surface recessed in a direction away from the ball head 121, and the depth of the concave spherical surface is not limited here, but is related to the diameter of the rubber column and the diameter of the ball head 121. The concave spherical surface is matched with the ball head 121, that is, the inner diameter of the concave spherical surface is the same as or approximately the same as the spherical diameter of the ball head 121.

In another possible embodiment, as shown in fig. 11, 12 and 13, the elastic member includes a spring 151 and an abutment member 152 fixed to one end of the spring 151, and an end surface of the abutment member 152 away from the spring 151 is a concave spherical surface, and the concave spherical surface is in mating abutment with the ball head 121.

In this embodiment, in order to secure a frictional damping force between the elastic member and the ball portion 121, an abutment member 152 is provided at the other end of the spring 151, and the abutment member 152 has a concave spherical surface, and a frictional damping force is formed between the concave spherical surface and the ball portion 121 by the cooperative abutment of the concave spherical surface and the ball portion 121. In addition, the concave spherical surface may be made of rubber, and the friction coefficient of the rubber is large, so that the friction damping force between the concave spherical surface and the ball head 121 can be further improved.

Alternatively, as shown in fig. 13, a sleeve 153 is sleeved outside the spring 151, the sleeve 153 and the abutting piece 152 are integrally formed, and one end of the spring 151 away from the abutting piece 152 extends out of the sleeve 153. By fitting the spring 151 into the sleeve 153, the possibility of the spring 151 being deformed obliquely during rotation of the main body 110 can be reduced. Through sleeve 153 and butt piece 152 integrated into one piece setting, the installation of host computer body 110 has effectually been simplified. By arranging the end of the spring 151 far away from the abutting piece 152 extending out of the sleeve 153, a gap is formed between the top wall of the accommodating cavity 114 and the end face of the end of the sleeve 153 far away from the concave spherical surface, so that the sleeve 153 can move up and down relative to the accommodating cavity 114 in the process of rotating the host body 110 relative to the ball rotating shaft 120, and interference of the host body 110 in the process of rotating relative to the ball rotating shaft 120 is reduced.

Further, the inner diameter of the accommodating cavity 114 is larger than the outer diameter of the sleeve 153, so that the sleeve 153 can move up and down in the accommodating cavity 114 in the process of rotating relative to the ball head rotating shaft 120, and larger pulling force at the joint of the ball head 121 and the shaft 122 in the ball head rotating shaft 120 is avoided, and the service life of the ball head rotating shaft 120 is prolonged.

In some embodiments, the end surface of the elastic member, which is used to abut against the ball head 121, is provided with a protrusion, and the surface of the ball head 121 is provided with a plurality of pits, the protrusion is matched with the pits, and the plurality of pits are arranged along the turning direction and/or the rotating direction of the host body 110.

Based on the above structure, when the host body 110 rotates along the overturning direction and/or the rotating direction, the protrusions on the end surface of the elastic member, which is used for abutting against the ball head 121, will sequentially enter the plurality of pits, and when the protrusions enter and exit the pits, the protrusions will make the host body 110 generate an obvious sense of a shift in the rotating process, and the sense of a shift is a shift hand feeling.

The turning direction may be a first preset direction, or the turning direction may be a third preset direction. The rotation direction may be a second predetermined direction.

The end surface of the elastic member, which is used to abut against the ball head 121, is a concave spherical surface, and the protrusion is located on the inner wall of the concave spherical surface.

The gear feeling is not limited to the above-mentioned scheme, and in another possible implementation manner, a plurality of pits may be formed on the inner wall of the spherical groove 111, and protrusions are formed on the inner wall of the concave spherical surface, so that the gear feeling can be generated during the rotation of the main body 110 relative to the ball pivot 120.

In order to facilitate the convenience of installing the ball spindle 120, in some embodiments, as shown in fig. 3, 11 and 13, a mounting opening 115 communicating with the accommodating cavity 114 is formed on a surface of the main body 110 away from the bearing plate 130, a sealing plug 140 is detachably connected to the mounting opening 115, and the diameter of the mounting opening 115 and the inner diameter of the accommodating cavity 114 are both larger than the diameter of the ball head 121.

In this embodiment, since the mounting opening 115 is in communication with the accommodating cavity 114, and the diameter of the mounting opening 115 and the inner diameter of the accommodating cavity 114 are both larger than the diameter of the ball head portion 121, when the ball head shaft 120 is mounted, the shaft portion 122 is made to put the ball head shaft 120 from the mounting opening 115 toward the bearing plate 130, and the ball head shaft 120 is made to sequentially enter the accommodating cavity 114 and the spherical groove 111, when the shaft portion 122 is extended from the through hole 113, the shaft portion 122 is fixed at the middle or angle of the edge of the bearing plate 130, and then the elastic member is mounted in the accommodating cavity 114, and the mounting opening 115 is closed by the closing plug 140, so that the mounting of the ball head shaft 120 is completed.

In order to avoid interference between the host body 110 and the carrier plate 130 when the host body 110 is turned in the first preset direction, in some possible embodiments, as shown in fig. 10, a chamfer 116 is formed on a side edge of the lower surface of the host body 110 near the ball groove 111, where the chamfer 116 may be a planar chamfer 116 or an arc chamfer 116, and thus, during the turning of the host body 110 in the first preset direction, a turning gap will exist between a side edge of the lower surface of the host body 110 near the ball groove 111 and the upper surface of the carrier plate 130.

In other embodiments, as shown in fig. 15, the upper surface of the bearing plate 130 is provided with an avoidance groove 131, and the avoidance groove 131 is used for avoiding the edge of the host body 110 when the host body 110 is turned in a direction away from the bearing plate 130.

Specifically, as shown in fig. 15, when the shape and the size of the upper surface of the carrier plate 130 and the lower surface of the host body 110 correspond, the avoidance groove 131 penetrates through the edge of the upper surface of the carrier plate 130, and in addition, when the spherical groove 111 is disposed at the corner of the host body 110, the host body 110 can also be turned relative to the ball pivot 120 along the third preset direction to switch between the horizontal screen and the vertical screen of the host body 110, so that the avoidance groove 131 needs to be disposed at the adjacent edge of the carrier plate 130, and thus, when the host body 110 is turned away from the carrier plate 130, the interference between the edge of the host body 110 and the carrier plate 130 can be avoided.

In addition, as shown in fig. 14, when the ball groove 111 is disposed at the corner of the main body 110, in order to mount the edge main body 110 on the bearing plate 130 through the ball spindle 120, a positioning protrusion 117 is disposed on the lower surface of the main body 110, and the positioning protrusion 117 is located at the edge of the through hole 113, and a positioning groove 132 is disposed at a position of the bearing plate 130 corresponding to the positioning protrusion 117.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
