DETAILED DESCRIPTION

[0046] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0047] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0048] The technical solution of the embodiment of the present disclosure is to solve the above technical problems, and the overall idea is as follows:

[0049] Example 1

[0050] Reference Figure 1 , Attachment Figure 5 And attached Fig. 9 The connecting device provided by the embodiment of the present disclosure includes a first shaft body 1, a second shaft body 2, a transmission assembly 3 and a support portion 4; the first shaft body 1 is used to connect the first body 5; the second shaft body 2 is used to connect the second body 6; the transmission assembly 3 is movably connected to the second shaft body 2, so that the transmission assembly 3 can reciprocate along the first direction a with the rotation of the second shaft body 2; the first direction a is parallel to the axial direction of the second shaft body 2; the support portion 4 is movably connected to the transmission assembly 3, so that the transmission assembly 3 reciprocates along the first direction a while the support portion 4 reciprocates along the second direction b; the second direction b has an angle with the first direction a.

[0051] Specifically, in order to solve the problem of poor user experience when the screen of a sinking 360-degree flip notebook is sunk, the connecting device provided in this embodiment is configured through the cooperation of the transmission component 3 and the support part 4, so that when the second axis 2 rotates relative to the first axis 1, the support part 4 can be driven to reciprocate along the second direction b through the transmission component 3. For the corresponding second body 6, when the first body 5 rotates relative to the second body 6 through the second axis 2, the transmission component 3 can drive the support part 4 to gradually extend or retract to the second body 6 to form a support, thereby preventing the first body 5 from sinking close to the edge of the second body 6 and touching the desktop or the supporting surface.

[0052] Among them, the first axis 1 and the second axis 2 are parallel to each other and the connection can be but not limited to forming a 360-degree dual-axis sinking shaft structure, which can be but not limited to a cylindrical shaft or a runway circular shaft, and can be but not limited to being used in a laptop computer. It can be understood that the first body 5 and the second body 6 can be but not limited to the screen end and the system end of the laptop computer. When the connecting device is assembled in the electronic device, the first body 5 can be flipped relative to the second body 6, and the flipping process includes the first rotation stroke of the first body 5 through the second axis 2, which is switched to the second rotation stroke of the first body 5 through the first axis 1 in the middle, and then switched to the third rotation stroke of the first body 5 through the second axis 2 again. The angle of each rotation stroke can be designed and adjusted according to actual needs, such as a first rotation stroke of 0-135 degrees, a second rotation stroke of 135-300 degrees, and a third rotation stroke of 300-360 degrees; it can be understood that the connecting device provided in this embodiment can adjust the extension and retraction of the support part 4 relative to the second body 6 during the first rotation stroke and the third rotation stroke, thereby effectively supporting the second body 6 and preventing the edge of the first body 5 from hitting the desktop or the supporting plane after sinking relative to the second body. It is not difficult to understand that two connecting devices are required in the electronic device, which are respectively provided at the two ends of the width direction of the first body 5 .

[0053] Among them, the support part 4 can be a rigid structure or an elastic structure, which is arranged in the second body 6, and can be extended and retracted relative to the second body 4 under the drive of the transmission assembly 3 to adjust the support height of the second body 6; the shape and size of the support part 4 can be designed and adjusted according to actual needs, and the support part 4 can be set in a long strip parallel to the second axis 4, or in a columnar shape perpendicular to the second axis 2, as long as the support strength for the second body 6 is guaranteed. It can be understood that the angle between the second direction b and the first direction a in this embodiment can be designed and adjusted according to actual needs, and can be but not limited to the angle that meets the vertical condition, that is, a vertical or nearly vertical angle.

[0054] Among them, the transmission component 3 is a rigid structure, which serves as the connection between the second shaft body 2 and the support part 4 and the power transmission object. It also flexibly connects the second shaft body 2 and the support part 4, and can convert the rotational movement of the second shaft body 2 into the linear motion of the support part 4, thereby realizing the linkage between the support part 4 and the second shaft body 2; the transmission component 3 can be a combination of a slider, a guide groove, and a connecting rod, or a combination of a cam group, a gear rack, and a screw.

[0055] According to the above, the connecting device provided by the present application, by cooperating with the transmission assembly 3 and the support part 4, enables the support part 4 to gradually extend and retract relative to the second body 6 during the rotation of the first body 5 relative to the second body 6 through the second axis 2, thereby ensuring that the support part 4 can provide sufficient support height during the flipping and sinking of the first body 5 relative to the second body 6, and preventing the bottom of the first body 5 from colliding with the support surface of the electronic device; thereby solving the problem of low user experience of the sinking 360-degree flip notebook when the screen sinks.

[0056] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B, which is specifically understood as: A and B may be included at the same time, A may exist alone, or B may exist alone, and any of the above three situations may exist.

[0057] Further, see Attachment Figure 1 To Attachment Figure 3 , Attachment Figure 5 and attached Figure 6 In the connection device provided in this embodiment, in a specific implementation, the transmission assembly 3 includes a first moving part 31, a second moving part 32 and a lifting part 33; the first moving part 31 is adapted to the guide area 21 of the second shaft body 2 to reciprocate along the first direction a; the second moving part 32 is parallel to the second shaft body 2 and connected to the first moving part 31, so that the first moving part 31 and the second moving part 32 reciprocate along the first direction a at the same time; the lifting part 33 extends along the second direction b and is movably connected to the second moving part 32, and the lifting part 33 is connected to the support part 4.

[0058] Specifically, in order to realize the conversion of the movement direction of the transmission component 3, it is configured in the present embodiment to include a first moving part 31, a second moving part 32 and a lifting part 33, and the first moving part 31, the second moving part 32 and the lifting part 33 are all rigid structural parts; accordingly, a guide area 21 is provided on the second shaft body 2, and the guide area 21 can be but not limited to a guide surface or a guide groove provided on the second shaft body 2; the guide area 21 cooperates with the first moving part 31, so that the first moving part 31 can move parallel to the axial direction of the second shaft body 2, that is, the first direction a, as the second shaft body 2 rotates, thereby driving the second moving part 32 to move relative to the second body 6 and the second shaft body 2 along the first direction a. It is not difficult to understand that the first moving part 31 and the second moving part 32 are in a fixed form, and at least the second moving part 32 needs to be slidably connected to the second body 5 in the first direction a through a sliding part, for example: a guide groove is provided on the second body 6, and a corresponding slider is provided on the second moving part 32. At the same time, the lifting part 33 and the second moving part 32 can be, but are not limited to, connected by a connecting rod or a screw-like structure, so that the linear motion of the moving part 32 can be converted into linear motion in the vertical direction, and then when the second moving part 32 reciprocates along the first direction a, the lifting part 33 can drive the supporting part 4 to reciprocate in the second direction b. It can be, but is not limited to, the reciprocating motion of the lifting part 33 in the second direction b drives the movement of the supporting part 4, or the supporting part 4 reciprocates in the second direction b relative to the lifting part 33.

[0059] Furthermore, in the specific implementation of the connection device provided in this embodiment, the setting mode of the guide area 21 includes at least the following two modes:

[0060] The first one, refer to the attached Figure 4 The second shaft body 2 is provided with a spiral groove along its axial direction to form the guide area 21; the first moving part 31 is provided with a guide part (not shown in the figure) adapted to the spiral groove.

[0061] Specifically, the spiral groove on the second shaft body 2 provides a spiral motion path. When the first motion part 31 cooperates with the spiral groove and the second body 6 , the movement of the first motion part 31 in the spiral groove can cause the first motion part 31 to reciprocate along the axial direction of the second shaft body 2 .

[0062] The second type, refer to the attached Figure 8 The second shaft body 2 is provided with a cam 22 , and the guide area 21 is formed on the cam 22 ; the first moving part 31 is provided with a cam matched with the cam 22 , and the cam is sleeved on the second shaft body 2 .

[0063] Specifically, the cam 22 provides a guide path on one side facing the cam, so that when the cam 22 rotates with the second shaft body 2 , the guide area, ie, the guide path, can be used to drive the cam to perform linear motion along the second shaft body 2 .

[0064] Further, see Attachment Figure 4 and attached Figure 8 Regardless of the first or second setting method mentioned above, the guide area 21 includes a first guide surface 23, a second guide surface 24 and a third guide surface 25 connected in sequence; the first guide surface 23 is arranged obliquely along the axial direction of the second shaft body 2, so that the support portion 4 is in the first position when the first moving portion 31 moves to the connection between the first guide surface 23 and the second guide surface 24; the second guide surface 24 is arranged perpendicular to the axial direction of the second shaft body 2, so that the support portion 4 maintains the first position when the first moving portion 31 moves on the second guide surface 24; the third guide surface 25 is arranged obliquely along the axial direction of the second shaft body 1, so that the support portion 4 is in the second position when the first moving portion 31 moves to the end of the third guide surface 25 away from the second guide surface 24.

[0065] Specifically, when corresponding to the spiral groove, the side wall of the spiral groove is the corresponding guide surface; when corresponding to the cam 22, the surface of the cam 22 facing the concave wheel is the corresponding guide surface. The first position is the maximum extension of the support part 4, and the second position is the maximum retraction of the support part 4. It can be understood that the inclination angles of the first guide surface 23 and the third guide surface 24 can be designed and adjusted according to actual needs, and can be the same or different. For example, referring to the above-mentioned first to third rotation strokes, the first rotation stroke can include two sub-strokes. The first sub-stroke is 0-90 degrees. The first moving part 31 moves from the starting end of the first guide surface 23 to the connection between the second guide surface 23 and the second guide surface 24. In this process, the extension degree of the support part 4 gradually increases to the maximum. The second sub-stroke is 90-135 degrees. The first moving part 31 is on the second guide surface 2 4, the first moving part 31 does not produce a linear displacement in the first direction a, and the extension degree of the support part 4 remains unchanged; the second rotation stroke is 135-300 degrees, during which the second shaft body 2 does not rotate, and the transmission assembly 3 and the support part 4 do not change position; the third rotation stroke is 300-360 degrees, during which the second shaft body 2 rotates, and the first moving part 31 moves from the connection between the second guide surface 24 and the third guide surface 25 to the end of the third guide surface 25 facing the first guide surface 23, and the retraction degree of the support part 4 gradually increases to the maximum during the process. It can be understood that the first guide surface 23 and the third guide surface 25 can be directly connected or can be connected through the fourth guide surface 26, and the fourth guide surface 26 can be perpendicular to the axial direction of the second shaft body 2, that is, Figure 4 and Figure 8 It can be understood that, corresponding to electronic devices, especially laptop computers, a fixed foot pad structure (not shown in the figure) is provided on the back of the second body 6 at one end away from the rotating shaft, and thus the support portion 4 provided in this embodiment will still reserve a portion exposed outside the second body 6 when in the second position, so as to cooperate with the fixed foot pad structure to ensure stable support of the electronic device.

[0066] Further, see Attachment Figure 1 and attached Figure 5 , in the connection device provided in this embodiment, in a specific implementation, the second moving part 32 can have at least the following two settings;

[0067] The first one, refer to the attached Figure 5 The second moving part 32 is a rack, the first end of the lifting part 33 is provided with a gear 34 adapted to the rack, and the second end of the lifting part 33 is connected to the supporting part 4, so that the second moving part 32 reciprocates along the first direction a while the supporting part 4 reciprocates along the second direction b.

[0068] Specifically, under this setting mode, the lifting part 33 and the support part 4 can be in the form of screw connection or fixed connection. When the two are in the form of screw connection, the lifting part 33 is a twill screw, and when the second moving part 32 moves along the first direction a, it can drive the gear 34 to rotate around the second direction b, and the lifting part 33 rotates around the second direction b with the gear 34, and the support part 4 makes a linear motion in the second direction b; when the two are in the form of fixed connection, the lifting part 33 needs to be screwed with the second body 6, and then the lifting part 33 rotates around the second direction b relative to the second body 6 and makes a linear motion along the second direction b, thereby driving the support part 4 to make a linear motion in the second direction b; of course, the screw connection between the lifting part 33 and the second body 6 here can be achieved by the mounting frame 61 of the connecting device. Accordingly, in order to cooperate with the extension and retraction of the support part 4, reference can be made to the attached Figure 7 , a corresponding sliding part is arranged on the mounting frame 61 , for example, a sliding groove 62 is arranged on the supporting part 4 , and a matching sliding block is arranged on the mounting frame 61 .

[0069] The second type, refer to the attached Figure 1 The second moving part 32 is configured as a slider, and the lifting part 33 includes a first connecting rod 35 ; the first end of the first connecting rod 35 is rotatably connected to the second moving part 32 , and the second end of the first connecting rod 35 is rotatably connected to the supporting part 4 .

[0070] Specifically, in this configuration, the first connecting rod 35 is a rigid rod body, which can be referred to in the attached Figure 2The movement of the second moving part 32 in the first direction a can drive the second end of the first connecting rod 35 to move in the second direction b. Further, a limiting groove 63 or a limiting cylinder along the second direction b can be set on the mounting frame 61 of the connecting device in the second body 6, so that when the second moving part 32 moves in the first direction a, the force is transmitted to the first connecting rod 35, and then the second end of the first connecting rod 35 intelligently moves the supporting part 4 along the second direction b within the range of the limiting groove 63.

[0071] Furthermore, in order to ensure the stable and labor-saving movement of the support part 4, a second connecting rod 36 can also be provided in the present embodiment. The first end of the second connecting rod 36 is spaced apart from the first end of the first connecting rod 35 in the opposite direction of the first direction a and is rotatably connected to the second body 6. The second end of the second connecting rod 36 is rotatably connected to the support part 4. The second connecting rod 36 and the first connecting rod 35 form a V-shaped frame, so that the lifting part 33 can drive the support part 4 in the second direction b more quickly and stably.

[0072] Further, see Attachment Figure 3 and attached Figure 6 The connecting device provided in this embodiment, in a specific implementation, further includes an elastic portion 7; the elastic portion 7 is arranged along the first direction a, and the elastic portion 7 abuts against the second moving portion 32 to provide a force to cooperate with the movement of the support portion 4 in the second direction b.

[0073] Specifically, in order to improve the smoothness of the support portion 4 extending out of the second body 6, reduce the force applied by the user, and improve the user experience, an elastic portion 7 is provided in this embodiment, and the elastic portion 7 can be but is not limited to a spring or a rubber member; corresponding to the two different second moving portions 32, the setting position and method of the elastic portion 7 are also different:

[0074] The first one, refer to the attached Figure 6 , corresponding to the case where the second moving part 32 is a rack, the elastic part 7 is arranged in the first direction of the second moving part 32, and the initial state of the elastic part 7 is a pre-compression state, that is, Figure 6 The leftmost end of the middle rack is meshed with the gear 34, and the elastic part 7 provides a force in the opposite direction of the first direction a. At this time, the first body 5 and the second body 6 of the electronic device are in a closed state parallel to each other. When the first body 5 rotates relative to the second body 6 through the second shaft 2, the rack moves in the opposite direction of the first direction a. Figure 6 The elastic portion 7 provides a force in the same direction, thereby accelerating the movement speed of the rack in the opposite direction of the first direction a and reducing the difficulty of the rack moving in this direction, thereby reducing the difficulty of the support portion 4 extending out of the second body 6.

[0075] The second type, refer to the attached Figure 3, when the second moving part 32 is a slider, the second moving part 32 is arranged in the first direction of the elastic part 7, and the initial state of the elastic part 7 is a pre-stretched state, that is, Figure 3 The middle slider is located at the rightmost end of the mounting bracket 61, and the elastic part 7 provides a force in the opposite direction of the first direction a. At this time, the first body 5 and the second body 6 of the electronic device are in a closed state parallel to each other. When the first body 5 rotates relative to the second body 6 through the second shaft 2, the slider moves in the opposite direction of the first direction a. Figure 3 The left side movement, at this time, he does not provide the same direction force 7, thereby accelerating the movement speed of the slider in the opposite direction of the first direction a and reducing the difficulty of the slider moving in this direction, thereby reducing the difficulty of the support part 4 extending out of the second body 6.
