Description

Technical Field

[0001] The utility model relates to the technical field of rotating shafts, in particular to a rotating shaft structure and an electronic product. Background Art

[0002] The system end and display end of the laptop are connected by a hinge. When the display end is rotated to open in the range of 45° to 60°, the distance between its rotation position and the system end is the smallest. In order to avoid interference / collision between the display end and the system end, the gap between the system end and the display end needs to be kept above 1 mm. Structurally, sufficient gap can be ensured by changing the structure of the display end or increasing the axis height of the hinge. However, the adjustment of the gap by changing the structure of the display end is limited due to space constraints. Regardless of whether it is a single-axis or dual-axis hinge, the axis height is fixed. If the axis height is increased, the diameter of the hinge needs to be changed, which will increase the thickness of the whole machine.

[0003] To solve the above problem, the guide rod and the locking mechanism can be used. That is, when the display end is opened, the guide rod is used to lift the display end to a certain height to ensure sufficient gaps and avoid interference / collision. However, the structure of this solution is more complicated, not only the cost is high, but also the guide rod and the locking mechanism are set independently, which will take up a large space of the product.

[0027] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0028] An embodiment of the utility model provides a rotating shaft structure, including a shaft assembly, a lifting assembly, a first support frame and a second support frame; the shaft assembly is used to provide a driving force for rotation, and the lifting assembly can be lifted a certain distance under the action of the shaft assembly, thereby achieving the purpose of increasing the distance between the first support frame and the second support frame.

[0029] The following is a detailed description of the components of the rotating shaft structure provided by the embodiment of the utility model, as well as the connection relationship and position relationship of the components, in conjunction with the accompanying drawings.

[0030] like Figures 1 to 4As shown, the shaft assembly 1 includes a parallel driving shaft 11 and a transmission shaft 12, one end of the driving shaft 11 is connected to the first support frame 3, for example, one end of the driving shaft 11 includes a connecting end, and a planar portion is provided on the connecting end, the first support frame 3 includes a connecting portion, the connecting portion includes a planar structure, the planar structure is fitted with the planar portion of the connecting end, and connecting holes are respectively provided on the connecting end and the connecting portion, and the two are fastened together by rivets. As the driving shaft 11 rotates, the first support frame 3 rotates synchronously with the rotating shaft.

[0031] The lifting assembly 2 includes a driving part 21 and a lifting part 22, wherein the driving part 21 is connected to the shaft assembly 1, and the lifting part 22 is connected to the second support frame 4, and the driving part 21 and the lifting part 22 are movably connected. The position of the second support frame 4 is changed by the lifting assembly 2, so that the distance between the first support frame 3 and the second support frame 4 is changed, wherein the driving of the lifting assembly 2 is completed by the driving shaft 11.

[0032] When the hinge structure is in use, the corresponding structures are connected by the first frame 3 and the second frame 4, respectively. For example, taking a laptop computer as an example, it includes a system end and a display end, which is connected to the display end of the laptop computer through the first frame 3, and is connected to the system end of the laptop computer through the second frame 4. When the display end is turned on, the active shaft 11 is driven to rotate by the display end, and the active shaft 11 drives the first frame 3 and the driving part 21 to rotate synchronously. At the same time, the driving part 21 drives the lifting part 22 to move, thereby realizing the movement of the second frame 4 to a set distance, and finally, the purpose of adjusting the distance between the first frame 3 and the second frame 4 is achieved. That is, when the interval between the first frame 3 and the second frame 4 is sufficient, it can avoid collision between the system end and the display end of the laptop computer during rotation.

[0033] For example, in the embodiment of the utility model, the driving part 21 includes a first gear 211 and a second gear 212, the lifting part 22 includes a linear toothed plate 221, and the second support frame 4 is connected to the linear toothed plate 221; the first gear 211 is sleeved on the driving shaft 11 and fixedly connected to the driving shaft 11, and the second gear 212 is sleeved on the transmission shaft 12 and fixedly connected to the transmission shaft 12. In the initial state, the first gear 211 and the second gear 212 are meshed, and the linear toothed plate 221 is meshed with the first gear 211; as the driving shaft 11 rotates, the first gear 211 rotates along the circumferential direction of the second gear 212, for example, the transmission shaft 12 is fixedly arranged, and the transmission shaft 12 and the second gear 212 thereon will not be driven to rotate by the first gear 211. When the first gear 211 rotates a certain distance circumferentially along the second gear 212, the linear gear plate 221 is driven to move by the first gear 211. The moving distance of the linear gear plate 221 is the same as the rotation distance of the first gear 211 on the second gear 212. For example, the first gear 211 rotates two teeth along the second gear 212. Similarly, the linear gear plate 221 is driven by the first gear 211 to move two teeth.

[0034] The structure of the linear tooth plate 221 can be understood as follows: the structure of the linear tooth plate 221 is a plate-like structure, and a tooth structure distributed along a straight line is arranged on a plane on one side of the plate-like structure.

[0035] For example, in the embodiment of the utility model, the second gear 212 is a gap gear; there is a set meshing arc between the first gear 211 and the second gear 212. The circumferential surface of the gap gear includes some teeth. For example, on the circumferential surface of the gap gear, two-thirds are arc-shaped structures, and the other one-third is provided with teeth, and the first gear 211 is partially meshed with the teeth. By setting the gap gear, it is possible to avoid the linear tooth plate 221 from being lifted up infinitely, that is, by determining the meshing amount between the gap gear and the first gear 211, the number of teeth (height) of the linear tooth plate 221 that are lifted up is determined.

[0036] As the first gear 211 rotates, in the initial state, the first gear 211 rotates along the teeth of the second gear 212 (gap gear), and the number of teeth of the two gears meshing and rotating is the same as the number of teeth lifted by the linear toothed plate 221. When the first gear 211 and the second gear 212 are not meshing, the first gear 211 and the linear toothed plate 221 remain in meshing state and rotate synchronously, wherein, in this rotating state, the first support frame 3 and the second support frame 4 rotate at the lifted interval.

[0037] For example, the tooth module of the first gear 211, the second gear 212 and the linear gear plate 221 is 0.25 mm. During the lifting process, the linear gear plate 221 is lifted by two teeth. It can be seen that the lifted height is 0.5 mm. For example, the starting distance between the first support frame 3 and the second support frame 4 is 0.8 mm. After the shaft structure rotates the set angle, the distance between the first support frame 3 and the second support frame 4 is 1.3 mm.

[0038] In the embodiment of the utility model, the lifting assembly 2 also includes a box body 23, the driving shaft 11 and the transmission shaft 12 pass through the box body 23, and the first gear 211 and the second gear 212 are arranged in the box body 23; the box body 23 includes a box opening 231, and the linear tooth plate 221 is buckled on the box opening 231 and slides on the box opening 231.

[0039] The housing 23 is provided with a through hole, and the driving shaft 11 and the transmission shaft 12 are provided on the housing 23 through the through hole. The driving shaft 11 and the transmission shaft 12 can rotate freely at the through hole position. For example, a bearing or other structure can be provided to assist the driving shaft 11 and the transmission shaft 12 to rotate.

[0040] The first gear 211 and the second gear 212 are both disposed in the housing 23, and the housing 23 protects the first gear 211 and the second gear 212, preventing external structures / components from entering the gear set and affecting the normal operation of the gears. For example, the thickness of the housing 23 is about 8 mm, which does not increase the size of the shaft structure.

[0041] In the embodiment of the utility model, a slide groove 232 is provided on the side wall of the box opening 231 along the sliding direction of the linear tooth plate 221 , and both sides of the linear tooth plate 221 are respectively arranged in the slide groove 232 on the same side; the linear tooth plate 221 slides along the slide groove 232 .

[0042] The direction of the slide groove 232 is the same as the sliding direction of the linear tooth plate 221, and the slide groove 232 has a limiting and guiding function. For example, a stop structure is set at the end position of the linear tooth plate 221, and the stop structure is used to abut against the end of the slide groove 232, wherein a sufficient sliding stroke is set at the front end of the stop structure. Under normal use, the stop structure and the slide groove 232 have no contact and limiting conditions, but the stop structure can limit the linear tooth plate 221 from sliding unrestricted in the slide groove 232, and can prevent the linear tooth plate 221 from falling off in the slide groove 232, thereby playing a stopping role.

[0043] In the embodiment of the utility model, the torsion assembly 5 of the rotating shaft structure is arranged on the driving shaft 11 and the transmission shaft 12, and is arranged side by side with the lifting assembly 2. For example, the torsion assembly 5 includes a plurality of torsion plates 51 stacked along the axial direction of the driving shaft 11 and the transmission shaft 12; one end of the torsion assembly 5 abuts against the limiting structure 52, and the other end abuts against the outer wall of the box body 23. When the driving shaft 11 rotates to the desired angle, under the action of the torsion assembly 5, it can be maintained at the current angle to prevent the driving shaft 11 and the transmission shaft 12 from rotating freely relative to each other. In the embodiment of the utility model, the structure of the torsion assembly 5 is not limited to the torsion plate 51, and it can also be other torsion structures.

[0044] The utility model also provides an electronic product, including the above-mentioned rotating shaft structure, through which the electronic product can complete the rotation of a set angle. For example, the electronic product includes a display end and a system end, and the housing of the display end and the housing of the system end are connected by the rotating shaft structure.

[0045] The housing of the display end is connected to the first support frame 3, and the housing of the system end is connected to the second support frame 4. In the initial state, there is a set fixed distance between the first support frame 3 and the second support frame 4. Figure 3 As shown, it is the starting state, the connection part between the first support frame 3 and the display end, and the connection part between the second support frame 4 and the system end are arranged in parallel. At this time, the relative angle between the first support frame 3 and the second support frame 4 is 0°, and the first gear 211 is respectively engaged with the second gear 212 and the linear gear plate 221.

[0046] When the display end is opened, the shell of the display end is pulled (such as manually), and the shell drives the active shaft 11 to rotate through the first support frame 3. As the active shaft 11 rotates, the first gear 211 rotates along the teeth of the second gear 212, and the linear gear plate 221 rotates along the teeth of the first gear 211, so that the linear gear plate 221 moves away from the system end, that is, moves away from the second support frame 4, thereby increasing the interval between the first support frame 3 and the second support frame 4, and achieving the purpose of lifting the display end.

[0047] When the display end and the driving shaft 11 continue to rotate and the linear end plate is lifted to the set position, the teeth of the first gear 211 and the second gear 212 (gap gear) are separated, and the first gear 211 and the second gear 212 are separated, and the two are in a non-meshing relationship, such as Figure 4 As shown, there is no relative driving relationship between the first gear 211 and the second gear 212 . As the transmission shaft 12 continues to rotate, the first gear 211 and the linear gear plate 221 rotate synchronously, but there is no relative movement between the first gear 211 and the linear gear plate 221 .

[0048] like Figure 3 and Figure 4As shown, the number of teeth rotating between the first gear 211 and the second gear 212 is two teeth, and the same linear toothed plate 221 is lifted by two teeth by the first gear 211. The lifting height of the two teeth is the set lifting height, that is, the lifting distance can be determined by adjusting the number of teeth meshing between the first gear 211 and the second gear 212.

[0049] As the driving shaft 11 continues to rotate, the first gear 211 and the second gear 212 rotate to the required angle in a non-meshing state. At this time, the display end and the system end continue to rotate at the interval after the distance is raised. Rotating at this interval can avoid / reduce interference between the display end and the system end.

[0050] For example, the electronic product is a laptop computer, and the display terminal and the system terminal are the display part and the system part of the laptop computer respectively. When using the laptop computer, it is necessary to manually pull the display terminal to open the display terminal to a certain angle. The above-mentioned hinge structure can increase the interval between the display terminal and the system terminal to avoid interference during the opening process.

[0051] When the display end starts to rotate, for example, the lifting of the second support frame 4 can be completed before rotating 30°. In the subsequent rotation process, it rotates after being lifted, that is, it rotates at a large spacing. Therefore, interference can be avoided / reduced.

[0052] The utility model provides a shaft structure and an electronic product, wherein a lifting assembly 2 is connected to a shaft assembly 1, and one of the supports can be lifted by the lifting assembly 2 as the shaft rotates, thereby increasing the interval between the two supports, increasing the axis height of the shaft, and effectively ensuring the distance between the supports. The technical solution of the utility model has a simpler structure and low cost while ensuring the stability of the axis height of the shaft, and combined with the shaft assembly, it will not cause the shaft structure to be excessively enlarged, and the required installation space is small.
