Description

Technical Field

[0001] This utility model relates to a hinge and an opening and closing device, and more particularly to a hinge with a liftable component and an opening and closing device having thereon. Background Technology

[0002] Laptops, foldable phones, and other devices have a structure with a top cover and a base that can be opened and closed relative to each other. The top cover and base are rotated relative to each other by a hinge with a pivot.

[0003] However, a hinge that only drives rotation is not enough. Due to the need for heat dissipation of the mechanism or to allow the casing to move, a special hinge is needed that can provide the function of separating the top cover from the base while rotating. Utility Model Content

[0004] Therefore, in order to solve the various problems of existing hinges, this utility model proposes a hinge with a lifting component and an opening and closing device having it.

[0005] To achieve the above and other objectives, this utility model proposes a hinge for a liftable component, comprising: a pivot shaft with a helical groove on its surface; a support frame with a lifting groove; a drive slider disposed between the pivot shaft and the support frame, the drive slider having a positioning post that can slide relative to the helical groove, the drive slider being connected to the support frame by a slide rail assembly to allow the drive slider to slide relative to the support frame, the slide rail assembly providing an inclined track; and a lifting bushing having a lifting bushing portion and a lifting slide post, the lifting bushing portion surrounding the pivot shaft, the lifting slide post being configured to slide within the lifting groove.

[0006] In one embodiment of the present invention, the support frame is provided with an inclined first slide rail, and the drive slider is provided with a first slide post that can slide relative to the first slide rail. The first slide rail and the first slide post form the slide rail assembly.

[0007] In one embodiment of the present invention, the drive slider is provided with an inclined second slide rail, and the support is provided with a second slide post that can slide relative to the second slide rail. The second slide rail and the second slide post form the slide rail assembly.

[0008] In one embodiment of the present invention, the drive slider further includes a drive shaft sleeve portion that surrounds the rotating shaft.

[0009] In one embodiment of the present invention, the positioning post is configured to be detachably disposed on the drive shaft sleeve.

[0010] In one embodiment of the present invention, a cellular support frame and an E-shaped buckle are also included. The cellular support frame has two cellular portions that surround the pivot. The E-shaped buckle is disposed between the two cellular portions and surrounds the pivot.

[0011] In one embodiment of the present invention, a fixed column is further included. The cellular support frame also has a support portion with an axial groove. The fixed column is fixedly connected to the drive slider and is configured to slide relative to it in the axial groove.

[0012] In one embodiment of the present invention, the cellular support frame further has a locking tenon portion, which interferes with the driving slider in the extension direction of the lifting groove.

[0013] In one embodiment of the present invention, the latch is a protrusion extending axially along the pivot, and the drive slider has a receiving portion that allows the protrusion to extend into it.

[0014] This utility model also proposes an opening and closing device, which includes: a base; a top cover; and a hinge for a liftable component as described above, the pivot being connected to the top cover and the support being connected to the base.

[0015] Therefore, the hinge of the liftable component of this utility model and the opening and closing device thereon can gradually lift the component connected to the rotating shaft by rotating the rotating shaft, thereby achieving the function of synchronous rotation and lifting.

[0066] To fully understand this utility model, the following specific embodiments, in conjunction with the accompanying drawings, provide a detailed description. Those skilled in the art can understand the purpose, features, and effects of this utility model from the content disclosed in this specification. It should be noted that this utility model can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the spirit of this utility model. The following embodiments will further describe the relevant technical content of this utility model in detail, but the disclosed content is not intended to limit the scope of the patent application of this utility model. The explanation is as follows:

[0067] like Figures 1 to 2B As shown, the opening and closing device 200 of this utility model embodiment includes a base B, a top cover C, and hinges 100 for the liftable components. The hinges 100 for the liftable components can be arranged in a single set or in multiple sets on the base B and the top cover C. In this embodiment, two sets of hinges 100 for the liftable components are symmetrically arranged on the base B and the top cover C.

[0068] like Figures 2A to 3A As shown, the hinge 100 of the liftable component includes: a pivot 1, a support 2, a drive slider 3, and a lifting bushing 4. The pivot 1 is connected to the upper cover C, and the support 2 is connected to the base B. The rotational power received by the pivot 1 comes from an external force driving the relative rotation of the upper cover C and the base B.

[0069] The surface of the rotating shaft 1 is provided with a helical groove 11, the helix direction of which is centered on the axial direction of the rotating shaft 1 (X-axis in the figure). The helical groove 11 can be directly formed on the surface of the rotating shaft 1 by machining (e.g., engraving), or it can be assembled by fitting a component with the helical groove 11 onto the rotating shaft 1. The rotating shaft 1 may further have a connecting seat 12 for connecting to the upper cover C. The upper cover C can rotate the rotating shaft 1 through the connecting seat 12.

[0070] The support frame 2 has a lifting groove 23, which extends in the predetermined lifting direction of the rotating shaft 1 (as shown by the Z-axis in the figure) and is substantially perpendicular to the axial direction of the rotating shaft 1. Of course, in special cases, the predetermined lifting direction of the rotating shaft 1 may not necessarily be perpendicular to the axial direction of the rotating shaft 1, but may be at an angle to the axial direction of the rotating shaft 1.

[0071] The drive slider 3 is disposed between the rotating shaft 1 and the support 2. The drive slider 3 has a positioning post 34 that can slide relative to the support 2 in the helical groove 11. The drive slider 3 is connected to the support 2 by a slide rail assembly, allowing the drive slider 3 to slide relative to the support 2. The purpose of the slide rail assembly is to provide an inclined track, allowing the drive slider 3 to move upwards at an angle relative to the support 2 (see reference). Figure 4B and Figure 5B The tilted arrow drives the slider 3 to move in a direction that includes a vector with positive X and positive Z axes.

[0072] There are various implementations of the specific structure of the slide rail assembly. In one embodiment, refer to... Figure 2A The support frame 2 has an inclined first slide rail 21, and the drive slider 3 has a first slide post 31 that can slide relative to the first slide rail 21. The first slide rail 21 and the first slide post 31 form a slide rail assembly. For ease of assembly, in this embodiment, the first slide post 31 can be integrally formed on the surface of the drive slider 3 by injection molding or other methods; however, the first slide post 31 can also be formed by assembly or other methods.

[0073] In another embodiment, the drive slider 3 has an inclined second slide rail 32, and the support 2 has a second slide post 22 that can slide relative to the second slide rail 32. The second slide rail 32 and the second slide post 22 form a slide rail assembly. For ease of assembly, in this embodiment, the second slide post 22 is formed on the surface of the support 2 in an assembled manner. Specifically, the support 2 has a second slide post hole 22a, and the separable second slide post part 22b passes through the drive slider 3 and is then assembled into the second slide post hole 22a. However, the present invention is not limited to this, and the second slide post 22 can also be integrally formed in other ways.

[0074] It should be noted that the slide rail assemblies in the two implementation methods described above are not mutually exclusive, and multiple sets of slide rail assemblies can be used simultaneously. For example Figure 2A The display support 2 and the drive slider 3 together have two sets of first slide rails 21 / first slide column 31 and two sets of second slide rails 32 / second slide column 22 to assist the drive slider 3 in sliding relatively in a balanced manner.

[0075] The lifting bushing 4 has a lifting bushing portion 41 and a lifting slide 42. The lifting bushing portion 41 surrounds the rotating shaft 1, and the lifting slide 42 is configured to slide in the lifting groove 23 of the support 2.

[0076] The following will explain how the hinge 100 of the liftable component of this utility model lifts the component (the upper cover C in this embodiment) connected to the pivot 1 by rotating the pivot 1.

[0077] like Figures 3A to 3D As shown, when the relative angle between the base B and the top cover C is 0 degrees, the distance between the axis of the rotating shaft 1 and the base B is L0.

[0078] Then as Figures 4A to 4D As shown, an external force is applied to cause the base B and the upper cover C to rotate relative to each other, thus rotating the shaft 1. The rotation of the shaft 1 causes the positioning pin 34 of the drive slider 3 to slide relative to each other in the helical groove 11, causing the drive slider 3 to move axially toward the shaft 1 (in the positive X-axis direction of the figure). An inclined track provided by a slide rail assembly (e.g., the aforementioned combination of the first slide rail 21 / first slide pin 31, or the combination of the second slide rail 32 / second slide pin 22) is provided between the drive slider 3 and the support frame 2, causing the drive slider 3 to move axially toward the shaft 1 (in the positive X-axis direction of the figure) while also gradually rising upwards (in the positive Z-axis direction of the figure). The upward movement of the drive slider 3 causes the shaft 1 to rise upwards. At this time, the distance between the axis of the shaft 1 and the base B is L1 (…). Figure 4D It can be seen that the distance L1 is longer than... Figure 3D The distance L0.

[0079] The base B and the upper cover C continue to rotate relative to each other, driving the slider 3 to continue to rise, thereby causing the rotating shaft 1 to rise. For example... Figures 5A to 5D As shown, when the positioning post 34 has completely slid to the other end of the spiral groove 11, the distance between the axis of the rotating shaft 1 and the base B is L2. Figure 5D It can be seen that the distance L2 is longer than... Figure 4D Distance L1 and Figure 3D The distance L0.

[0080] Although this embodiment uses 0 degrees, 67.5 degrees, and 135 degrees as examples for explanation, it is not limited to specific angles to achieve the lifting effect. In fact, the change in the opening and closing angle of the hinge 100 of the lifting component of the present invention is a gradual relationship with the displacement of the lifting stroke, rather than a staged change.

[0081] It should be explained in detail that the function of the lifting sleeve 4 is to restrict the axial displacement of the rotating shaft 1. When the drive slider 3 slides at an angle, the sliding direction includes the X-axis and Z-axis in the figure. The rotating shaft 1 is restricted by the lifting slide post 42 and can only slide in the lifting groove 23, thus restricting the axial displacement of the rotating shaft 1. From another perspective, it is precisely because the axial displacement of the rotating shaft 1 is restricted that the positioning post 34 of the drive slider 3 can slide along the helical groove 11, thus producing movement in the X-axis direction in the figure. The design of the lifting sleeve 4 and the design of the positioning post 34 / helical groove 11 complement each other.

[0082] In summary, the hinge 100 of the liftable component of this utility model can be rotated to allow the rotating shaft 1 (connected to the upper cover C) to gradually move away from the support frame 2 connected to the base B, thereby achieving synchronous rotation and lifting. Conversely, if the upper cover C is rotated in the opposite direction to cover the base B, the upper cover C can return to its initial position from its lifted state.

[0083] It needs to be explained in detail that the way the drive slider 3 is connected to the rotating shaft 1 must ensure that the drive slider 3, although not rotating synchronously with the rotating shaft 1, can still push the rotating shaft 1 to lift upwards / retract downwards. The simplest approach is to rely solely on the positioning pin 34 to push the rotating shaft 1 upwards / retract downwards by pushing the wall of the spiral groove 11. However, a drive shaft sleeve 33 can be further provided in the drive slider 3, surrounding the rotating shaft 1. Through the drive shaft sleeve 33, the drive slider 3 can push the rotating shaft 1 upwards / retract downwards without rotating synchronously with the rotating shaft 1. In this embodiment, the positioning pin 34 is provided in the drive shaft sleeve 33, and the drive shaft sleeve 33 also protects the positioning pin 34 from falling out. For ease of assembly, the positioning pin 34 is designed to be detachably disposed within the drive shaft sleeve 33. One approach is to use a pin 35 passing through the drive shaft sleeve 33 and the positioning pin 34 to laterally fix the positioning pin 34. However, this utility model is not limited to this. The positioning post 34 can be detachably installed in the drive shaft sleeve 33 or in other positions of the drive slider 3 through other forms of mechanism, or it can be integrally formed in the drive shaft sleeve 33 or in other positions of the drive slider 3. This utility model does not limit the specific position and detailed arrangement of the positioning post 34.

[0084] Other methods of connecting the drive slider 3 to the rotating shaft 1 can also be achieved indirectly. For example, as... Figure 2A and Figure 2B The hinge 100 of the liftable component shown also includes a cellular support frame 5, which has at least one cellular portion 51 and a latch portion 53. The cellular portion 51 surrounds the pivot 1, and the latch portion 53 interferes with the drive slider 3 in the extending direction of the lifting groove 23. The drive slider 3 is indirectly connected to the pivot 1, allowing it to push the pivot 1 upwards / downwards even though it does not rotate synchronously with the pivot 1. Specifically, in this embodiment, the latch portion 53 is a protrusion extending axially along the pivot 1, and the drive slider 3 has a receiving portion 36 that allows the protrusion to extend into it (see...). Figure 3C , 4C (5C). However, the latch 53 and the receiving portion 36 may not be in the form shown in this embodiment, and may be other structures that interfere with each other in the extension direction of the lifting groove 23. In addition, the way the drive slider 3 of this utility model is connected to the rotating shaft 1 is not limited to being through the cellular support frame 5.

[0085] Since the drive slider 3 has a displacement vector along the axial direction (X-axis in the figure), while the cellular support frame 5 and the rotating shaft 1 do not move accordingly, the drive slider 3 and the cellular support frame 5 must also be connected in the form of a slide rail. Specifically, in this embodiment, the hinge 100 of the liftable component further includes a fixing post 7, and the cellular support frame 5 also has a support portion 52, which has an axial groove 521. The fixing post 7 is fixedly connected to the drive slider 3 by assembly or integral molding, and is configured to slide relative to it in the axial groove 521.

[0086] Furthermore, the hinge 100 of the liftable component also includes an E-type retaining ring 6. The cellular support frame 5 has two cellular portions 51, and the E-type retaining ring 6 is disposed between the two cellular portions 51 and surrounds the rotating shaft 1. The E-type retaining ring 6 holds the rotating shaft 1 and can rotate with the rotating shaft 1. The E-type retaining ring 6 protrudes from the surface of the rotating shaft 1, and its main function is to interfere with the cellular portions 51 in the axial direction of the rotating shaft 1 to prevent the rotating shaft 1 from falling out in the opposite direction.

[0087] Furthermore, the hinge 100 of the liftable component also includes a hinge cover 8, which covers multiple structures such as the pivot 1, the drive slider 3, and the lifting bushing 4, and can protect these components from being exposed.

[0088] This utility model has been disclosed above with examples; however, those skilled in the art should understand that these examples are merely illustrative and should not be construed as limiting the scope of the utility model. It should be noted that all variations and substitutions equivalent to these examples should be considered within the scope of this utility model. Therefore, the protection scope of this utility model should be determined by the claims.
