Detailed Description

Fig. 1 to 3 show an embodiment of a pivoting device 1000 of the present invention, the pivoting device 1000 is connected between a display 2000 and a stand 3000, so that the display 2000 can rotate around a central axis X facing a user. Referring to fig. 4 to 6, the pivoting device 1000 includes a base 1, a shaft 2, a rotating member 3, a sliding member 4, an elastic member 5, a nut 6 and a plurality of spring washers 7, wherein the shaft 2 defines a central axis X.

Referring to fig. 1 and 7, the seat body 1 is connected to the upright column 3000, and preferably, the seat body 1 can be tilted with respect to the upright column 3000 and has three stop blocks 11, and the stop blocks 11 respectively have two opposite stop surfaces 111 for contacting and interfering with the rotating member 3.

The shaft 2 is fixed on the seat 1, and more specifically, the shaft 2 penetrates through the seat 1, and the nut 6 is screwed on the shaft 2 to fix the shaft 2 on the seat 1, the shaft 2 has a head 21, and the head 21 and the nut 6 together clamp the seat 1 from two sides.

Referring to fig. 8, the rotating member 3 is pivotally sleeved on the shaft center 2 and connected to the display 2000. The rotating member 3 includes a first abutting portion 31, two stopping rods 32 and a first central hole 33. The first abutting portion 31 has a plurality of first protruding regions 311 and a plurality of first recessed regions 312. The first recessed areas 312 are respectively formed between the first protruding areas 311, a first central angle θ 1 is formed between adjacent first protruding areas 311 with the central axis X as a center, and a first central angle θ 1 is formed between adjacent first recessed areas 312, and the first protruding areas 311 and the first recessed areas 312 are connected in a staggered manner in the circumferential direction with the central axis X as a center, so that the surface of the first abutting portion 31 is wavy. The stop rod 32 is configured to interfere with the stop block 11, and when the rotating member 3 rotates at a certain angle relative to the central axis X, the stop rod 32 contacts the stop surface 111 to be limited. It should be noted that the pivoting device 1 can achieve the limiting effect only by one stop rod 32 and two stop blocks 11, in the embodiment, the two stop rods 32 and three stop blocks 11 are taken as an example for illustration, and can be configured according to the positioning requirement of the rotation of the display 2000. The first central hole 33 is for the shaft 2 to pass through, and the first central hole 33 is circular, so that the rotating member 3 can rotate relative to the shaft 2. Further, since the stopper bar 32 abuts against the seat body 1 in the direction of the central axis X, the rotation member 3 is restricted from moving along the central axis X.

Referring to fig. 9, the sliding member 4 includes a second abutting portion 41, a second central hole 42 and a receiving groove 43. The sliding member 4 is sleeved on the shaft center 2 and can slide along the central axis X relative to the shaft center 2, and in detail, the second central hole 42 is used for the shaft center 2 to penetrate through, and the cross-sectional shapes of the second central hole 42 and the shaft center 2 are non-circular and correspond to each other, so that the sliding member 4 can only move relative to the shaft center 2 and cannot rotate relative to the shaft center 2. The second abutting portion 41 has a plurality of second protruding regions 411 and a plurality of second recessed regions 412, the second recessed regions 412 are respectively formed between the second protruding regions 411, the adjacent second protruding regions 411 sandwich a first central angle θ 1 circle with the central axis X as the center, the adjacent second recessed regions 412 sandwich the first central angle θ 1 circle, the second protruding regions 411 and the second recessed regions 412 are connected in a staggered manner in the circumferential direction with the central axis X as the center, so that the surface of the second abutting portion 41 is wavy. The second contact portion 41 is constantly in contact with the first contact portion 31 due to being pushed by the elastic member 5. Normally, the second protruding portion 411 is received in the first recessed portion 312, and the second recessed portion 412 is used for receiving the first protruding portion 311, so that the rotating member 3 and the sliding member 4 are tightly attached. The receiving groove 43 is used for receiving the elastic element 5.

The elastic element 5 is abutted between the base 1 and the sliding element 4, and the accommodating groove 43 has a limiting function, so that the elastic element 5 can be partially arranged in the accommodating groove 43 to maintain the elastic element to provide an elastic force along the central axis X without deviation. The elastic member 5 is preferably a compression spring, and in other embodiments, the elastic member 5 may be another member providing an elastic force parallel to the central axis X.

The spring washer 7 is sleeved on the shaft center 2 and clamped between the head 21 and the rotating piece 3, the spring washer 7 can be used as a friction piece when the shaft center 2 and the rotating piece 3 rotate relatively, and can be used for adjusting the hand feeling when the rotating piece 3 rotates relative to the shaft center 2.

The following describes the actuation relationship of the components of the pivoting device 1000 of the present invention. Normally, the first abutting portion 31 and the second abutting portion 41 are matched, the rotating member 3 and the sliding member 4 are in an abutting state, and each of the stop rods 32 is in contact with one of the stop blocks 11. When an external force is applied to rotate the rotating member 3 relative to the shaft center 2, the degree of interference between the first abutting portion 31 and the second abutting portion 41 increases, and the sliding member 4 is pushed by the rotating member 3 to move along the central axis X toward the seat body 1 and compress the elastic member 5. As the rotation member 3 rotates relative to the shaft center 2, the degree of interference between the first protruding section 311 and the second protruding section 411 increases. When the external force is removed, the elastic element 5 pushes the sliding element 4 to move towards the rotating element 3, the second abutting portion 41 pushes the first abutting portion 31, and tends to push the first abutting portion 31 to a position with a low degree of interference, so that the rotating element 3 is pushed by the sliding element 4 to rotate relative to the sliding element 4, and finally the rotating element 3 and the sliding element 4 return to the attached state.

In detail, the rotation of the rotation member 3 is divided into the following two cases. When the rotating member 3 is rotated by an external force relative to the sliding member 4 and the external force is removed before the top end of the first protruding area 311 crosses the top end of the second protruding area 411, the sliding member 4 will reset the rotating member 3, so that the rotating member 3 and the sliding member 4 are restored to the attached state.

However, when the rotating member 3 is rotated relative to the sliding member 4 by an external force and the external force is removed after the top end of the first protruding region 311 crosses the top end of the second protruding region 411, the sliding member 4 rotates the rotating member 3 until the first protruding region 311 corresponds to another adjacent second recessed region 412, the first recessed region 312 corresponds to another adjacent second protruding region 411, and the rotating member 3 and the sliding member 4 are restored to the attached state, so that the rotating member 3 is rotated by the first central angle θ 1 before receiving the external force.

By the above mechanism, the joint state can be limited to two predetermined rotation limit positions (shown in fig. 2 and fig. 3, respectively) of the display 2000, and an intermediate position between the rotation limit positions (corresponding to a state where the first protruding region 311 and the second protruding region 411 contact each other) is used as a boundary point to distinguish the rotation tendency of the first contact portion 31 and the second contact portion 41 for assisting the rotation. Referring to fig. 2 as an initial state, when the user rotates the display 2000 around the central axis X, the pivoting device 1000 tends to rotate the display 2000 back to the original position (see fig. 2) by the interference-assisted rotation of the first abutting portion 31 and the second abutting portion 41 when the user rotates the display 2000 not beyond the intermediate position, and when the user rotates the display 2000 beyond the intermediate position, the pivoting device 1000 tends to rotate the display 2000 to another rotation limit position (see fig. 3) which is rotated by the first central angle θ 1 compared to the initial position.

In the present embodiment, the first central angle θ 1 is 90 degrees, and the display 2000 can be switched between a vertical swing (raster mode) and a horizontal swing (landscape mode) in this configuration. Each of the stop rods 32 defines a second central angle θ 2 with the central axis X as a center, and a third central angle θ 3 is formed between two adjacent stop surfaces 111 of two adjacent stop blocks 11 with the central axis X as a center, so that the stop rods 32 can rotate the first central angle θ 1 between the stop surfaces 111, and the angle of the third central angle θ 3 between the stop surfaces 111 is the sum of the first central angle θ 1 and the second central angle θ 2.

It should be noted that, in other embodiments, the first central angle θ 1 is not necessarily 90 degrees, but is preferably a multiple of 90 degrees. In addition, the arrangement of the stop block 11 and the stop rod 32 can be changed, for example, the position between two rotation limit positions can be changed to cover more fitting states, so that the display 2000 has multi-stage and larger rotation relative to the rotation of the upright post 3000, and even the stop block 11 and the stop rod 32 can be omitted according to the requirement, so that the rotation range of the display 2000 is not limited.

In summary, when the user pivots the display, the interference of the first abutting portion and the second abutting portion can assist the display to rotate to the positioning position, so that the display has a better hand feeling compared with the known pivoting mechanism, and in the positioning of the display, the first abutting portion and the second abutting portion are in a stable bonding state with low interference, so that the angle of the display can be maintained to be fixed and not to rotate.

The above-mentioned embodiments are only used for illustrating the embodiments of the present disclosure and illustrating the technical features of the present disclosure, and are not used to limit the scope of the present disclosure. Any modification, equivalent replacement, improvement and the like made without departing from the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure. The protection scope of the claims of the present disclosure shall be subject to the protection scope of the claims.
