[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 lifting component, comprising: a pivot shaft with a helical groove on its surface; a pivot shaft carrier connected to the pivot shaft, the carrier being configured to be independent of the pivot shaft's rotation but capable of moving the pivot shaft in a lifting direction different from the pivot shaft's axial direction; a support frame with a shaft hole; a drive slider having a threaded portion that engages with the helical groove, the drive slider also having a hollow area with a toothed groove on the side of the hollow area away from the pivot shaft; and at least one drive gear. The drive gear, located in the hollowed-out area, includes a tooth and a protrusion. The tooth meshes with the tooth groove, and the protrusion is eccentric to the center of the drive gear. The protrusion is inserted into the shaft hole and is configured to interfere with the support in the lifting direction. An axial slide rail assembly includes an axial slide rail formed in the rotating shaft carrier, a receiving hole formed in the drive slider, and a slide post. The axial slide rail extends along the axial direction, and the slide post is disposed in the receiving hole and configured to slide within the axial slide rail. The rotating shaft carrier is connected to the drive slider in the lifting direction via the slide post.

[0006] In one embodiment of the present invention, the drive slider further has a bushing portion through which the rotating shaft passes.

[0007] In one embodiment of the present invention, the drive slider is disposed between the rotating shaft carrier and the support frame.

[0008] In one embodiment of the present invention, a first lifting member is further included. The support frame has a first lifting groove along the lifting direction. The first lifting member is connected to the drive slider and is configured to slide in the first lifting groove.

[0009] In one embodiment of this utility model, the number of drive gears is two, and the number of shaft holes is two.

[0010] In one embodiment of the present invention, a retaining member is further included, disposed between the two drive gears, and an arc-shaped slide rail is provided on each of the opposite sides of the retaining member so that the drive gear rotates along the arc-shaped slide rail.

[0011] In one embodiment of the present invention, a second lifting member is further included. The support has a second lifting groove along the lifting direction. The second lifting member is fixed to the supporting member and is configured to slide in the second lifting groove.

[0012] In one embodiment of the present invention, a fixing member is further included, which passes through the drive gear and is connected to the rotating shaft carrier.

[0013] In one embodiment of the present invention, the rotating shaft carrier further includes an E-shaped buckle and two circular portions, the two circular portions surrounding the rotating shaft, and the E-shaped buckle being disposed between the two circular portions and surrounding the rotating shaft.

[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.

[0072] 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:

[0073] 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 a hinge 100 for a liftable component. The hinge 100 for the liftable component can be a single set or multiple sets can be set on the base B and the top cover C. In this embodiment, two sets of hinges 100 for the liftable component are symmetrically set on the base B and the top cover C.

[0074] like Figures 2A to 3A As shown, the hinge 100 of the liftable component includes: a pivot 1, a pivot carrier 2, a support frame 3, a drive slider 4, at least one drive gear 5, and an axial slide rail assembly 6. The pivot 1 is connected to the upper cover C, and the support frame 3 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.

[0075] 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.

[0076] The rotating shaft carrier 2 is connected to the rotating shaft 1. The rotating shaft carrier 2 is configured to be independent of the rotation of the rotating shaft 1, and can move the rotating shaft 1 in a lifting direction (Z-axis direction) different from the axial direction of the rotating shaft 1 (X-axis direction in this embodiment). In this embodiment, the lifting direction is perpendicular to the axial direction of the rotating shaft 1, but this invention is not limited to this. In other cases, the lifting direction may not be perpendicular to the axial direction of the rotating shaft 1, but rather at a non-right angle to the axial direction of the rotating shaft 1. That is, the design of the lifting direction can be changed as needed. In this embodiment, the specific form of the rotating shaft carrier 2 is that the cellular portion 24 of the rotating shaft carrier 2 surrounds the rotating shaft 1, so that the rotating shaft 1 does not pull the rotating shaft carrier 2 to rotate along with it when it rotates, but the displacement of the rotating shaft carrier 2, including at least the lifting direction, will cause the rotating shaft 1 to move together. However, this invention is not limited to this, and the specific structure of the rotating shaft carrier 2 can be arbitrarily adjusted as needed. Any structure that can drive the rotating shaft 1 to a displacement other than the axial direction and is not affected by the rotation of the rotating shaft 1 can be used in the rotating shaft carrier 2 of this utility model.

[0077] The support frame 3 has a shaft hole 33. The support frame 3 is a structure fixedly connected to the base B and can be regarded as an extension of the base B. Therefore, the various possible rotations and / or displacements generated by the upper cover C pushing the rotating shaft 1 are movements relative to the support frame 3 and the base B.

[0078] The drive slider 4 has a threaded portion 41, which is threaded into the helical groove 11, so that the drive slider 4 is driven by the rotating shaft 1. Figure 2A As shown, the drive slider 4 also has a hollow area 42 along the axial direction of the rotating shaft 1, and a toothed groove 422 is provided on the side of the hollow area 42 away from the rotating shaft 1. The so-called side away from the rotating shaft 1 refers to the side away from the rotating shaft 1 after it is lifted.

[0079] like Figure 2A and Figure 3A As shown, at least one drive gear 5 is disposed in the hollow area 42. The drive gear 5 includes a tooth 51 and a protrusion 52. The tooth 51 meshes with the tooth groove 422, and the protrusion 52 is eccentric to the center of the drive gear 5. The protrusion 52 is inserted into the shaft hole 33 of the support 3 and is configured to interfere with the support 3 in the lifting direction. That is, the shape of the shaft hole 33 and the protrusion 52 may not be perfectly matched. The shaft hole 33 is slightly larger than the protrusion 52, which may cause the protrusion 52 to move in the shaft hole 33. However, if the protrusion 52 attempts to move in the lifting direction, it will be restricted by the interference of the shaft hole 33. In this embodiment, the hinge 100 of the liftable component has two drive gears 5, which are axially distributed in the hollow area 42 and mesh with the tooth groove 422 respectively, so as to achieve a more balanced and stable driving lifting effect. However, the present invention is not limited to this. There may be only one or more drive gears 5, and the number can be changed as needed.

[0080] like Figure 2A As shown, the axial slide rail assembly 6 includes an axial slide rail 61 formed in the rotating shaft carrier 2, a receiving hole 62 formed in the drive slider 4, and a slide post 63. The axial slide rail 61 extends axially, and the slide post 63 is disposed in the receiving hole 62 and configured to slide within the axial slide rail 61. The rotating shaft carrier 2 is connected to the drive slider 4 in the lifting direction via the slide post 63, and the sliding of the slide post 63 on the axial slide rail 61 allows the drive slider 4 and the rotating shaft carrier 2 to be axially separated.

[0081] 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.

[0082] 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.

[0083] Then as Figures 4A to 4D As shown, an external force is applied to cause the base B and the top cover C to rotate relative to each other, and the rotating shaft 1 rotates accordingly. The rotation of the rotating shaft 1 causes the threaded part 41 of the drive slider 4 to be pushed by the helical groove 11 and to be displaced relative to each other along the axial direction, so that the drive slider 4 moves toward the axial direction of the rotating shaft 1 (in the positive X-axis direction in the figure).

[0084] like Figure 4A As shown, the axial movement of the drive slider 4 causes the tooth groove 422 to also move axially, thereby driving the drive gear 5 meshing with the tooth groove 422 to rotate. Since the protrusion 52 is eccentric to the center of the drive gear 5, meaning the protrusion 52 is not located at the center of the drive gear 5, when the tooth 51 is driven to rotate, the protrusion 52 tends to produce a displacement in the lifting direction; in this embodiment, this displacement is in the opposite direction to the lifting direction (downward). See reference... Figures 3A to 4A Due to the difference in position, the protrusion 52 gradually descends towards the tooth groove 422 in the hollow area 42. However, the protrusion 52 is actually inserted into the shaft hole 33, and the protrusion 52 is configured to interfere with the support 3 in the lifting direction. That is to say, although the protrusion 52 itself is restricted by the support 3 and cannot generate displacement in the lifting direction (Z-axis), once a force "displacement in the opposite direction to the lifting direction" is applied to the protrusion 52, it will cause the other parts of the drive gear 5 to lift in the positive lifting direction; that is, the drive gear uses the protrusion 52-shaft hole 33 as the fulcrum, and the other parts of the drive gear 5 move relative to the protrusion 52 as the fulcrum. Returning to the figure, from Figure 3A , Figures 4A to 5AThe changes show that the position of the protrusion 52 relative to the drive slider 4 gradually decreases (opposite to the lifting direction). However, the protrusion 52, the support 3, and the base B connected to the support 3 are all fixed in the lifting direction. Instead, the drive slider 4 is driven upward along the lifting direction (positive Z-axis) by the teeth 51 of the drive gear 5. When the other parts of the drive gear 5 are lifted relative to the protrusion 52, which serves as a fulcrum, the drive slider 4, meshing with the teeth 51, is also lifted. In other words, when the shaft 1 rotates, the drive slider 4 will simultaneously produce displacement along the axial direction and along the lifting direction.

[0085] The following explains how to make the drive slider 4 transmit displacement to the rotating shaft 1 only in the lifting direction.

[0086] The sliding column 63 is disposed in the receiving hole 62 of the drive slider 4 and is configured to slide in the axial slide rail 61. That is, the drive slider 4 can generate relative displacement along the axial direction with the rotating shaft carrier 2 through the sliding column 63. Therefore, the relative displacement of the drive slider 4 in the axial direction will not be transmitted to the rotating shaft 1 through the rotating shaft carrier 2. However, the rotating shaft carrier 2 is linked to the drive slider 4 in the lifting direction through the sliding column 63. Specifically, for example, the axial slide rail 61 and the sliding column 63 interfere in the lifting direction. Once the drive slider 4 is displaced in the lifting direction, it will drive the rotating shaft carrier 2 to move together through the sliding column 63. The rotating shaft carrier 2 is configured to drive the rotating shaft 1 to move in the lifting direction. Therefore, the drive slider 4 only transmits the displacement along the lifting direction to the rotating shaft 1.

[0087] In summary, when the top cover C and the base B rotate relative to each other, the base B and the support frame 3 remain stationary. The rotating shaft 1 rotates and displaces in the lifting direction. The rotating shaft support frame 2 does not rotate with the rotating shaft 1 but drives the rotating shaft 1 to displace in the lifting direction. The driving slider 4 simultaneously generates displacement along the axial direction and along the lifting direction. The driving gear 5 rotates in the hollow area 42 of the driving slider 4 and displaces along the lifting direction.

[0088] Therefore, by causing the upper cover C to rotate relative to the base B, the rotating shaft 1 is driven. The rotating shaft 1 is displaced in the lifting direction through the hinge 100 of the liftable component of this utility model, thereby lifting the upper cover C. Figure 3D and Figure 4D As shown, when the upper cover C and the base B rotate relative to each other from 0 degrees to 67.5 degrees, the distance between the axis of rotation 1 and the base B changes from L0 to L1. It can be seen that distance L1 is longer than... Figure 3D The distance L0. For example... Figure 5D As shown, the base B and the upper cover C continue to rotate relative to each other, driving the slider 4 to continue to rise, thereby causing the rotating shaft 1 to rise. When the angle between the upper cover C and the base B changes to 135 degrees, the distance between the axis of the rotating shaft 1 and the base B becomes L2. It can be seen that the distance L2 is longer than... Figure 4DDistance L1 and Figure 3D The distance L0.

[0089] 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 this utility model is a gradual relationship with the displacement of the lifting stroke, rather than a staged change.

[0090] Furthermore, in this embodiment, as Figure 2A As shown, the drive slider 4 also has a bushing portion 43, through which the rotating shaft 1 is configured to pass. The design of the bushing portion 43 allows the drive slider 4 to be directly connected to the rotating shaft 1 without being affected by the rotation of the rotating shaft 1. Furthermore, the axial displacement of the drive slider 4 will not affect the rotating shaft 1, but can only be connected to the displacement in the lifting direction. The bushing portion 43 is preferably connected to both ends of the rotating shaft 1 with the screw portion 41 respectively, so as to connect the rotating shaft 1 in a balanced manner.

[0091] Furthermore, in this embodiment, as Figure 2A As shown, the drive slider 4 is plate-shaped and disposed between the rotating shaft carrier 2 and the support frame 3. For ease of use and assembly, and since the drive slider 4 primarily provides functions in the axial and lifting directions, it is preferably shaped as a plane formed by the axial and lifting directions and sandwiched between the rotating shaft carrier 2 and the support frame 3. However, this invention is not limited to this; the drive slider 4 can still be presented in other structures, and the relative positions of the rotating shaft carrier 2, the support frame 3, and the drive slider 4 can be changed according to requirements.

[0092] Furthermore, in this embodiment, as Figure 2A As shown, the hinge 100 of the liftable component also includes a first lifting member 71. The support 3 has a first lifting groove 31 along the lifting direction. The first lifting member 71 is connected to the drive slider 4 and configured to slide in the first lifting groove. The design of the first lifting member 71 and the first lifting groove 31 is to stabilize the displacement of the drive slider 4 relative to the support 3 in the lifting direction. See also Figure 3B , Figure 4B and Figure 5BThe changes are as follows. In this embodiment, the first lifting member 71 passes through the hole 44 of the driving slider 4 and is connected to the driving slider 4. Since the displacement of the driving slider 4 relative to the support 3 includes both axial and lifting directions, the extension direction of the hole 44 includes both axial and lifting directions, while the first lifting groove 31 only has a lifting direction. In this embodiment, for ease of manufacturing, the hole 44 is connected to the hollow area 42, but the present invention is not limited to this. In addition, the purpose of the driving slider 4 is to drive the rotating shaft carrier 2 to move in the lifting direction, so the first lifting member 71 can also pass through the driving slider 4 and be fixed in the first hole 21 of the rotating shaft carrier 2, so that the rotating shaft carrier 2 and the driving slider 4 together are stably displaced relative to the support 3 in the lifting direction. However, the present invention is not limited to this, and the first lifting member 71 can only connect either the rotating shaft carrier 2 or the driving slider 4.

[0093] Furthermore, in this embodiment, as Figure 2A As shown, there are two drive gears 5 and two shaft holes 33. The hinge 100 of the lifting component also includes a retainer 8, which is disposed between the two drive gears 5. An arc-shaped slide rail is provided on each of the opposite sides of the retainer 8 so that the two drive gears 5 can rotate along the arc-shaped slide rail respectively, thereby stabilizing the drive gears 5 and preventing them from disengaging from the hollow area 42.

[0094] Furthermore, in this embodiment, as Figure 2A As shown, the hinge 100 of the liftable component also includes a second lifting member 72, and the support 3 has a second lifting groove 32 along the lifting direction. The second lifting member 72 is fixed to the retaining member 8 and configured to slide in the second lifting groove 32. The design of the second lifting member 72 and the second lifting groove 32 is to stabilize the displacement of the drive slider 4 relative to the support 3 in the lifting direction. See also Figure 3B , Figure 4B and Figure 5B The second lifting member 72 passes through the hole 81 of the retaining member 8 and is indirectly connected to the driving slider 4 via the driving gear 5. Furthermore, the purpose of the driving slider 4 is to drive the rotating shaft carrier 2 to move in the lifting direction. Therefore, the second lifting member 72 can also pass through the retaining member 8 and be fixed in the second hole 22 of the rotating shaft carrier 2, so that the rotating shaft carrier 2 and the driving slider 4 together move stably relative to the support frame 3 in the lifting direction. However, this invention is not limited to this; the second lifting member 72 may connect only to either the rotating shaft carrier 2 or the retaining member 8.

[0095] Furthermore, in this embodiment, as Figure 2AAs shown, the hinge 100 of the liftable component also includes a fixing member 9, which passes through the hole 53 of the drive gear 5 and is connected to the third hole 23 of the rotating shaft carrier 2. The purpose of the fixing member 9 is to maintain stability between the drive gear 5 and the rotating shaft carrier 2, and the fixing member 9 preferably passes through the center of the drive gear 5 to avoid interfering with the movement of the drive gear 5.

[0096] Furthermore, in this embodiment, as Figure 2A As shown, the rotating shaft carrier 2 also includes an E-type retaining ring 25 and two circular portions 24. The two circular portions 24 surround the rotating shaft 1. In addition to transmitting displacement, including at least in the lifting direction, as mentioned above, the circular portions 24 can also provide rotational torque. The E-type retaining ring 25 secures the rotating shaft 1 and can rotate with it. The E-type retaining ring 25 protrudes from the surface of the rotating shaft 1, and its main function is to interfere with the circular portions 24 in the axial direction of the rotating shaft 1 to prevent the rotating shaft 1 from falling out in the opposite direction.

[0097] Furthermore, the hinge 100 of the liftable component also includes a hinge cover K, which covers multiple structures such as the pivot 1, pivot carrier 2, support frame 3, and drive slider 4, and can protect these components from being exposed.

[0098] 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.
