Detailed Description

The core of the application is to provide the electronic equipment, and user experience in a screen rotation process is improved.

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 of 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 and fig. 2, an embodiment of the present application provides an electronic device, including a rotating body 1, a supporting frame, and a gravity balance mechanism 3; the rotating body 1 is rotatably connected to the support frame, and the rotating body 1 can rotate around a rotating point; gravity balance mechanism 3 sets up in the support frame, and gravity balance mechanism 3 is connected with the focus position 5 of rotating body 1, and gravity balance mechanism 3 can exert the effort opposite with the gravity direction to the focus position all the time at the rotatory in-process of rotating body 1 to with the gravity balance of rotating body 1.

This electronic equipment's rotatory body 1 revolutes the in-process that the rotation point is rotatory in the support frame, 3 gravity balance mechanism exert with the reverse effort of gravity direction to the focus position 5 of rotatory body 1, this effort and rotatory body 1's gravity are balanced each other, thereby the rotatory resistance of rotatory body 1's self gravity pairing rotation body 1 production has been eliminated, only leave the rotatory resistance of rotatory body 1 and support frame's rotation junction friction production, then it is irrelevant with rotatory body 1's weight size and turned angle to rotate the required power of rotatory body 1, thereby user experience of using has been improved.

The embodiment provides a specific gravity balance mechanism 3, which comprises a horizontal guide structure 31, a moving member 33 and a constant force elastic member 32; the horizontal guide structure 31 is fixedly arranged on the support frame along the horizontal direction, and the horizontal guide structure 31 is still relative to the support frame all the time and is kept horizontal all the time; the moving member 33 is movably arranged on the horizontal guide structure 31 along the horizontal direction, the moving member 33 is matched with the horizontal guide structure 31, and the moving member 33 moves along the horizontal direction through the horizontal guide of the horizontal guide structure 31; both ends of the constant force elastic member 32 are connected to the moving member 33 and the gravity center position 5 of the rotating body 1, respectively.

If the rotating body 1 rotates, the gravity center position 5 can make circular motion around the rotating point of the rotating body 1 in the rotating plane formed by the rotation of the rotating body 1, because the gravity center position 5 is connected with one end of the constant force elastic part 32, the gravity center position 5 can make circular motion along with the gravity center position 5, the gravity center position 5 acts on the constant force elastic part 32, so that one end of the constant force elastic part 32 connected with the gravity center position 5 can move along with the other end of the constant force elastic part 32 is connected with the moving part 33, the constant force elastic part 32 generates acting force, the acting force is separated in the horizontal direction, and then the horizontal component of the acting force of the constant force elastic part 32 drives the moving part 33 to move correspondingly on the horizontal guide structure 31, so that the moving part 33 and the gravity center position 5 are kept in the same vertical direction.

This gravity balance mechanism 3's horizontal guide structure 31 is fixed in the support frame, the support frame rotates and supports rotating body 1, and the one end of constant force elastic component 32 passes through moving member 33 and moves along the horizontal direction and set up in horizontal guide structure 31, the barycenter position 5 of rotating body 1 is connected to the other end of constant force elastic component 32, therefore, the support of constant force elastic component 32 through the support frame, the effort opposite with the gravity direction is applyed to rotating body 1, no matter how the constant force elastic component 32 moves, the effort size that constant force elastic component 32 produced is invariable, this invariable effort is balanced each other with rotating body 1's gravity all the time. Thereby eliminated the rotation resistance that the self gravity of rotating body 1 produced to rotating body 1, only left the rotation resistance that the rotation junction friction of rotating body 1 and support frame produced, then rotated the required power of rotating body 1 and have had nothing to do with the weight size and the turned angle of rotating body 1 to user's use experience has been improved.

Further, in this embodiment, the support frame includes supporting part and fixed frame 2, the supporting part is used for supporting the rotation of rotatory body 1, fixed frame 2 is fixed in the supporting part, fixed frame 2 is motionless, rotatory body 1 is rotatory relative to fixed frame 2, horizontal guide structure 31 is fixed in fixed frame 2, thereby guaranteed that horizontal guide structure 31 remains the horizontal direction all the time and arranges, the turning point of rotatory body 1 is located fixed frame 2, it connects inside fixed frame 2 to rotate directly promptly rotatory body 1, also can rotate with the supporting part and be connected, fixed frame 2 encloses around the turning point of rotatory body 1. Constant force elastic component 32 and moving member 33 all are located fixed frame 2, hide and protect through fixed frame 2, and the both ends of horizontal guide structure 31 extend to fixed frame 2's inner wall, carry on spacingly through fixed frame 2 to the both ends of horizontal guide structure 31 to avoid moving member 33 to remove at the both ends of horizontal guide structure 31 and deviate from.

In this embodiment, as the rotating body 1 rotates continuously in a certain direction, the gravity center position 5 of the rotating body 1 also rotates continuously in a certain direction, and if the gravity center position 5 is located in the lower region of the horizontal guide structure 31 during the rotation, the constant force elastic member 32 is located below the horizontal guide structure 31 and between the horizontal guide structure 31 and the gravity center position 5, and the constant force elastic member 32 applies a constant force to the gravity center position 5 to face away from the gravity center position.

If the gravity center position 5 is located in both the lower area of the horizontal guide structure 31 and the upper area of the horizontal guide structure 31 during the rotation, the constant force elastic member 32 is always located below the horizontal guide structure 31 when the gravity center position 5 moves in the lower area of the horizontal guide structure 31, and the constant force elastic member 32 applies a constant force to the gravity center position 5, which is directed away from the gravity center position 5, and the direction of the force is opposite to the gravity direction of the rotating body 1.

When the gravity center position 5 moves in the upper region of the horizontal guide structure 31, the constant force elastic member 32 is always located above the horizontal guide structure 31, and the constant force elastic member 32 applies a constant force to the gravity center position 5 toward the gravity center position 5, in which the direction of the force is opposite to the gravity direction of the rotating body 1.

Therefore, no matter how the relative position of the gravity center position 5 and the horizontal guiding structure 31 is, how the rotating body 1 rotates within 360 degrees, the constant force elastic part 32 can always apply a constant acting force opposite to the gravity direction to the gravity center position 5, so that the constant acting force is balanced with the gravity, the rotating resistance generated by the gravity to the rotating body 1 is offset, only the rotating resistance generated by the friction of the rotating connection part of the rotating body 1 and the supporting frame is left, the force required for rotating the rotating body 1 is irrelevant to the weight size and the rotating angle of the rotating body 1, and the use experience of a user is improved.

In the present embodiment, the rotation point of the rotating body 1 is located at the geometric center position 6 of the rotating body 1, and the geometric center position 6 and the center of gravity position 5 of the rotating body 1 are not coincident, so that the gravity balance mechanism 3 can counteract the spatial gravity when the rotating body 1 rotates. Since the geometric center position 6 of the rotating body 1 does not coincide with the center of gravity position 5, if the rotation point is set at the geometric center position 6, the center of gravity position 5 makes a circular motion around the geometric center position 6 during the rotation of the rotating body 1, and if the rotation angle θ of the rotating body 1 is in the range of 0 ° to 90 ° and the center of gravity position 5 is located below the geometric center position 6, the motion of the center of gravity position 5 is similar to a simple pendulum motion, such as the motion trajectory of the center of gravity position 5 shown in fig. 3. The gravity at the center of gravity position 5 generates a rotational resistance to the rotating body 1, and therefore, the gravity balance mechanism 3 cancels out the spatial gravity when the rotating body 1 rotates.

In this case, since the movement speed generated by the rotation of the rotating body 1 is controlled by the user, the constant force elastic member 32 is usually a constant force spring, and in order to enable the constant force spring to bear the maximum movement speed generated by the rotation of the rotating body 1 without failure and provide a constant force for the balance weight, it is necessary to finally determine the stress limit and change of the constant force spring according to the maximum speed of the rotation of the rotating body 1, the swing angle θ of the center of gravity position 5 relative to the geometric center position 6, the mass of the rotating body 1, and other factors, and then select the constant force spring with suitable material, number of turns, resilience coefficient, and the like according to the stress limit.

Of course, when the rotation point of the rotating body 1 is located at the geometric center position 6 of the rotating body 1, the geometric center position 6 and the center of gravity position 5 of the rotating body 1 may be overlapped, so that the gravity balance mechanism 3 can counteract the gravity acting on the rotation shaft when the rotating body 1 rotates. Because the gravity center position 5 coincides with the geometric center position 6, in the rotating process of the rotating body 1, the position of the gravity center position 5 in the space is always unchanged, the gravity balance mechanism 3 does not move along with the rotation of the rotating body 1, the structure is simpler, and the rotating friction force generated by gravity on the rotating body 1 can be more simply counteracted.

In this embodiment, the rotating body 1 is rotatably connected to the supporting frame through the rotating shaft, and in the axial space parallel to the axial direction of the rotating shaft, the position of the horizontal guiding structure 31 and the position of the rotating shaft are arranged in a staggered manner and have an interval space, and the constant-force elastic member 32 can move in the interval space. So set up, when rotatory body 1 revolves the pivot rotation, the motion of constant force elastic component 32 can not receive the blockking and interfering of pivot, guarantees that constant force elastic component 32 normally works.

The embodiment provides a specific horizontal guiding structure 31, the horizontal guiding structure 31 is a horizontal guide rail, the moving member 33 is a slider structure or a roller structure movably matched with the horizontal guide rail, and the moving member 33 is driven by the constant-force elastic member 32 to move along the horizontal guide rail. The horizontal guide rail only provides vertical upward supporting force for the sliding block structure and the roller structure, and the rotary body 1 is suitable for the condition that the gravity center position of the rotary body 1 only moves in the lower area of the horizontal guide rail. The horizontal guide rail is simple in structure, and only a sliding block structure or a roller structure is required to be placed on the horizontal guide rail.

The present embodiment provides another horizontal guiding structure 31, the horizontal guiding structure 31 is a horizontal guiding groove, the moving member 33 is a sliding block structure disposed in the horizontal guiding groove in a fitting manner, and the moving member 33 is driven by the constant force elastic member 32 to move along the horizontal guiding groove. Horizontal guide slot can carry out the upper and lower spacing of vertical direction to the slider structure, and the slider structure can only be in horizontal guide slot horizontal migration, is applicable to the condition of the regional motion in the top of horizontal guide slot and below of the focus position of rotating body 1, and application scope is wider.
