As shown in fig. 1 to 6, the lifting linkage structure of the swing-screen camera provided in this embodiment includes: the device comprises a bracket 10, a screen swing connecting seat 20, a fixed rail 31, a movable rail 32 and a camera mounting seat 40; the screen swing connecting seat 20 is rotatably pivoted on the bracket 10 and is used for connecting the display 1.
The fixed rail 31 is fixedly arranged on the bracket 10, and the movable rail 32 is movably arranged on the fixed rail 31; the camera mounting seat 40 is disposed at one end of the movable rail 32 away from the pivot center of the swing-screen connecting seat 20, and is used for mounting the camera 2.
The camera mounting seat 40 and the movable rail 32 are integrally arranged in a T shape, and the lower parts of the left side surface 43 and the right side surface 43 of the camera mounting seat 40 are respectively provided with a rolling piece 60; the rolling piece 60 protrudes out of the side surface of the camera mounting seat 40; the bottom of the camera mounting seat 40 is provided with a sliding working surface 41 between the two rolling elements 60; the display 1 and the screen swing connecting seat 20 swing towards one direction, the camera mounting seat 40 tends to move downwards, and the camera mounting seat 40 is abutted against the frame of the display 1 through a rolling piece 60 and moves relatively along the frame of the display 1; when the camera mount 40 moves relatively and passes (or climbs over) the corner of the frame of the display 1, the camera mount 40 sequentially abuts against the display 1 (corner) through the rolling member 60, the sliding working surface 41 and the rolling member 60.
Specifically, the lower portion of the left side surface 43a of the camera mount 40 is provided with a left rolling piece 61 and a right rolling piece 62; left and right rolling members 61 and 62 are provided to protrude from left and right side surfaces 43a and 43b of the camera mount 40, respectively.
The side surface of the display 1 comprises a first frame 1a and a second frame 1b which are adjacent to each other; the abutment of the first frame 1a and the second frame 1b constitutes the corner portion (generally, a transitional arc surface) of the display 1.
As shown in fig. 4, which is a schematic structural diagram of the linkage structure when the back of the display is seen forward, as shown in fig. 4, the display 1 and the swing-screen connecting seat 20 swing to the right (clockwise), and the camera mounting seat 40 abuts against the first frame 1a of the display 1 through the right rolling member 62 and moves relatively along the first frame 1a of the display 1.
When the camera mount 40 moves relatively through (or overturns) the corner, the camera mount 40 sequentially abuts against the display 1 through the right rolling member 62, the sliding working surface 41 and the right rolling member 62.
On the contrary, the display 1 and the screen swing connecting seat 20 swing to the left (anticlockwise), and the camera mounting seat 40 is abutted against the first frame 1a of the display 1 through the left rolling element 61 and moves relatively along the first frame 1a of the display 1; when the camera mount 40 moves relatively through (or overturns) the corner, the camera mount 40 sequentially abuts against the display 1 through the left rolling member 61, the sliding working surface 41 and the left rolling member 61.
In the present invention, when the display 1 is normally used, the user faces the screen of the display 1, and the left-right hand direction of the user is defined as left and right sides, respectively.
The invention has a particularly simple structure, the camera mounting seat 40 tends to move downwards under the action of self gravity and/or the gravity of the movable rail 32 and/or the reset force of the reset piece, so that the camera can always move along the high-difficulty track of the relative movement of the edge of the display 1 when the display 1 and the screen swing connecting seat 20 swing and rotate, which is expected by a user, by adopting the extremely simple structure. In the swinging process of the display 1, the camera cannot be separated from the frame of the display 1 midway, and cannot turn over along with the display 1, so that the appearance looks very beautiful and elegant, and the moving track 32 of the camera expected by a user is realized.
In the above-described technical solution, more preferably, as shown in fig. 5 and 6, the rolling members 60 are disposed so as not to protrude downward from the sliding surface 41 in the height direction. That is, in the high east direction, the sliding surface 41 is flush with the lowest point of the outer circular rolling surface of the rolling member 60, or the sliding surface 41 is provided below the rolling member 60. When the display 1 does not rotate and the first frame is in a horizontal state, the camera mount 40 abuts against the first frame of the display 1 through the sliding working surface 41.
For convenience of description, the present invention defines the top surface of the display that is located above as the first frame, rather than defining the fixed frame of the display.
When the rolling element 60 moves relatively from the first frame 1a to the second frame 1b through the corner of the display, that is, at the moment when the rolling element 60 moves relatively through the end of the first frame 1a, the first frame 1a cannot support the camera mount 40 through the rolling element 60, and at this moment, the second frame 1b cannot support the camera mount 40 through the rolling element 60 immediately and continuously; in the height direction, when the rolling member 60 is provided to protrude downward from the sliding surface 41, the camera mount 40 drops at this instant, and the corner of the display 1 abuts on the sliding surface 41 (or the bottom surface of the camera mount 40), thereby causing vibration and noise problems.
According to the invention, the rolling elements are contracted above the sliding working surface 41 or flush with the bottom, so that the problem that the camera mounting seat 40 instantaneously drops and vibrates when the corner is overturned can be effectively avoided, and the linkage of the camera mounting seat 40 is smoother.
When the display 1 and the screen swing connecting seat 20 swing, in a projection plane perpendicular to the pivot axis of the screen swing connecting seat 20, the rolling element 60 relatively moves to the corner and the tail end of the first frame 1a of the display 1, and the extension line of the second frame 1b passes through the pivot center O of the rolling element 60, the intersection point of the extension line of the second frame 1b and the rolling working surface (or called as the outer circle rolling surface) of the rolling element 60 is defined as a crossing node J1, the camera mounting seat 40 further comprises a smooth transition cambered surface 42, and two ends of the smooth transition cambered surface 42 are respectively connected with the crossing node J1 and the sliding working surface 41; in the height direction, the rolling element 60 does not protrude from the smooth transition cambered surface 42, so that the corner of the display screen relatively moves to the position where the rolling element 60 passes over the junction J1, and then smoothly relatively slides to the sliding working surface 41 through the smooth transition cambered surface 42, the display continues to turn over, and finally, the rolling element 60 collides with the second frame 1b through the transition of the sliding working surface 41, and the rolling element continuously relatively moves along the second frame 1 b.
In the above-described aspect, it is more preferable that the center of the rolling member 60 is not disposed to protrude outward from the side surface 43 of the camera mount 40 in a projection plane perpendicular to the pivot axis of the swing joint base 20. Thereby facilitating the provision of a smooth transitional cambered surface 42 between the side surface 43 and the sliding surface 41. In the above-described technical solution, more preferably, as shown in fig. 5 and 6, in a projection plane perpendicular to the pivot axis of the swing-screen connector 20, the flip-over joint J1 is not disposed to protrude outward from the side surface 43 of the camera mount 40.
When the rolling element 60 relatively moves to the position of the turning joint J1 at the corner of the display screen through the first frame 1a of the display screen, in a projection plane perpendicular to the pivot axis of the screen swing and connection seat 20, an intersection point of a perpendicular line passing through the center of the rolling element 60 and the first frame 1a is defined as a lower limit joint J3, and an intersection point of the perpendicular line and the bottom of the rolling working surface of the rolling element 60 is defined as an upper limit joint J2; in the height direction, the sliding surface 41 is disposed between an upper limit node and a lower limit node, or the sliding surface 41 passes through the upper limit node or the lower limit node. The smooth transition arc 42 is disposed between the rolling member 60 and the first frame 1a (including the smooth transition arc 42 being tangential to the rolling member 60 or the first frame 1 a).
As shown in fig. 5 and 6, the sliding surface passing through the upper limit joint J2 is defined as an upper limit surface 41a, and the sliding surface passing through the lower limit joint J3 is defined as a lower limit surface 41b. Preferably, the height of the sliding surface is set between the upper limit surface 41a and the lower limit surface 41b (including the upper limit surface 41a and the lower limit surface 41 b).
In this embodiment, the camera mount 40 is preferably elongated, and the camera 2 is disposed at a central position thereof. The rolling elements 60 are preferably rolling bearings. The bearing outer ring is rotatably arranged and is abutted against the frame of the display 1. Of course, there are many forms of rolling elements 60, such as rollers, rotatably mounted shafts, etc.
In addition, the camera mounting seat 40 is fixedly connected with the movable rail 32. A plurality of balls are arranged between the movable rail 32 and the fixed rail 31, and the movable rail 32 is arranged on the fixed rail 31 in a linear movement manner through the balls.
Namely, the movable rail 32 and the fixed rail 31 form a sliding rail structure, and the sliding rail structure comprises the fixed rail 31, the movable rail 32, a plurality of balls and a ball retainer; the fixed rail 31 is arranged on the fixed rail 31 in a rolling and movable way through a plurality of balls, and the ball retainer is used for keeping two adjacent balls arranged at intervals.
The camera mount 40 tends to move downwards under the action of its own weight and/or the weight of the movable rail 32 and/or the restoring force of the restoring member and is abutted against the rim of the display 1 by the rolling member 60.
The camera mount 40 tends to move downward by the restoring force of the restoring member, which may be a coil spring, a wrap spring, or a tension (pull) gas spring, and is abutted against the bezel of the display 1 by the rolling member 60.
In this embodiment, the movable rail 32 is hollow, and the power line and/or the data line 50 are connected to the camera 2 through the hollow.
Further, the movable rail 32 is erected, and the movable rail 32 is movable in the up-down direction.
In the present application, for convenience of description, the left-right hand direction of the user facing the display 1 is defined as left side and right side, respectively.
As shown in fig. 4, a mounting groove is provided below the side surface of the camera mount 40, and the rolling member 60 is disposed in the mounting groove. In addition, the rolling element 60 may further include a body and an elastic shock absorbing rubber ring, and the elastic shock absorbing rubber ring is sleeved on the outer circle of the body. Preferably, the outer circle of the body is provided with a mounting ring groove, and the elastic damping rubber ring is sleeved in the mounting ring groove. The rolling surface of the rolling member 60 refers to the outer circumferential surface of the elastic shock-absorbing rubber ring.
The invention has a particularly simple structure, and particularly realizes the high-difficulty track movement of the camera which can be always in fit with the relative movement along the edge of the display 1 when the display 1 and the screen swing connecting seat 20 swing and rotate expected by a user by using the extremely simple structure. In the process of swinging the display 1, the camera cannot be separated from the frame of the display 1 midway, and cannot turn over along with the display 1, so that the appearance is attractive and elegant.
