The technical solutions disclosed in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1 to 7, an embodiment of the present application discloses a hinge, which includes a rotating shaft 100, a first rotating portion 200, and a second rotating portion 300.
Wherein, in the extending direction of the rotating shaft 100, the first rotating portion 200 and the second rotating portion 300 are sequentially and rotatably sleeved on the rotating shaft 100, specifically, the first rotating portion 200 has been provided with a first rotating hole, the second rotating portion 300 has been provided with a second rotating hole, and the first rotating hole and the second rotating hole are both in rotating fit with the rotating shaft 100. The first rotating portion 200 is provided with a first magnetic member 210, the second rotating portion 300 is provided with a second magnetic member 310, the first magnetic member 210 is magnetically matched with the second magnetic member 310, and the first magnetic member 210 and the second magnetic member 310 may be permanent magnets or electromagnets, which is not limited in the embodiment of the present application. Note that the extending direction of the rotating shaft 100 is the direction of the rotation axis of the first rotating portion 200 relative to the second rotating portion 300.
The hinge is switchable between a folded state in which the first rotating portion 200 is located at a first position with respect to the second rotating portion 300 and an unfolded state in which the first rotating portion 200 is located at a second position with respect to the second rotating portion 300; in the process of switching the hinge, the first rotating portion 200 further has a third position with respect to the second rotating portion 300, and the third position is located between the first position and the second position. In general, in the folded state of the hinge, the included angle between the first rotating part 200 and the second rotating part 300 is 0 degree, and of course, the included angle between the first rotating part 200 and the second rotating part 300 may also be 1 degree, 5 degrees, 10 degrees, and the like; when the hinge is in the unfolded state, the included angle between the first rotating part 200 and the second rotating part 300 is 180 degrees, and of course, the included angle between the first rotating part 200 and the second rotating part 300 can also be 170 degrees, 190 degrees, and the like; when the first rotating portion 200 is located at the third position relative to the second rotating portion 300, that is, the hinge is in the half-unfolded state, an included angle between the first rotating portion 200 and the second rotating portion 300 may be 90 degrees, and of course, the included angle between the first rotating portion 200 and the second rotating portion 300 may also be 80 degrees, 100 degrees, and the like, which is not limited in the embodiment of the present application.
When the first rotating part 200 rotates from the first position to the third position or rotates from the second position to the third position relative to the second rotating part 300, the magnetic cooperation between the first magnetic member 210 and the second magnetic member 310 provides damping for the first rotating part 200, when the user drives the first rotating part 200 to rotate from the first position to the third position relative to the second rotating part 300 or rotates from the second position to the third position, the magnetic cooperation between the first magnetic member 210 and the second magnetic member 310 can prevent the first rotating part 200 from rotating relative to the second rotating part 300, so that the user can drive the first rotating part 200 to rotate relative to the second rotating part 300 with a larger driving force, and the first rotating part 200 is prevented from rotating relative to the second rotating part 300 more easily in the hinge folded state or the unfolded state, thereby preventing the hinge from being kept in the folded state or the unfolded state more easily, thereby preventing the hinge from being loose.
When the first rotating part 200 rotates from the third position to the first position or rotates from the third position to the second position with respect to the second rotating part 300, the magnetic cooperation between the first magnetic member 210 and the second magnetic member 310 drives the first rotating part 200 to rotate, when the user drives the first rotating part 200 to rotate from the third position to the first position or to rotate from the third position to the second position with respect to the second rotating part 300, the magnetic cooperation between the first magnetic member 210 and the second magnetic member 310 can drive the first rotating part 200 to rotate relative to the second rotating part 300, which acts as an auxiliary for the user to drive the hinge, so that the hinge can be unfolded or folded faster, and at the same time, the driving force can prevent the first rotating part 200 from being reversed relative to the second rotating part 300, thereby avoiding the situation that the first rotating part 200 shakes relative to the second rotating part 300 and further preventing the hinge from being loosened.
In a specific using process, when the hinge is switched from the folded state to the half-unfolded state, the magnetic cooperation between the first magnetic member 210 and the second magnetic member 310 hinders the first rotating portion 200 from rotating, and at this time, a user needs to increase a driving force to drive the first rotating portion 200 to rotate; when the hinge is switched from the half-unfolded state to the unfolded state, the magnetic cooperation between the first magnetic member 210 and the second magnetic member 310 drives the first rotating part 200 to rotate, so that the hinge can be switched to the unfolded state quickly; when the hinge is switched from the unfolded state to the folded state, the magnetic cooperation between the first magnetic member 210 and the second magnetic member 310 hinders the rotation of the first rotating part 200, and at this time, a user needs to increase the driving force to drive the first magnetic member 210 to rotate, and at the same time, the hindering force can prevent the first rotating part 200 from easily rotating relative to the second rotating part 300, so that the first magnetic member 210 can be prevented from being reversed, and the hinge can be stably in the unfolded state; when the hinge is switched from the half unfolded state to the folded state, the magnetic engagement between the first magnetic member 210 and the second magnetic member 310 drives the first rotating portion 200 to rotate, so that the hinge can be switched to the folded state relatively quickly, and at the same time, the driving force can prevent the first rotating portion 200 from rotating relatively easily with respect to the second rotating portion 300, so that the first magnetic member 210 can be prevented from being reversed, so that the hinge is stably in the folded state.
In the hinge disclosed in the present application, the first rotating portion 200 is provided with the first magnetic member 210, the second rotating portion 300 is provided with the second magnetic member 310, when the first rotating portion 200 rotates from the first position to the third position or rotates from the second position to the third position relative to the second rotating portion 300, the magnetic engagement between the first magnetic member 210 and the second magnetic member 310 provides damping for the first rotating portion 200, and when the first rotating portion 200 rotates from the third position to the first position or rotates from the third position to the second position relative to the second rotating portion 300, the magnetic engagement between the first magnetic member 210 and the second magnetic member 310 drives the first rotating portion 200 to rotate. Under the condition, the hinge can realize damping rotation without a spring, so that the hinge cannot be stably kept in a folded state or an unfolded state due to the fatigue effect of the spring, and under the condition that the folding screen mobile phone is provided with the hinge, two main bodies of the folding screen mobile phone are difficult to relatively rotate, so that the folding screen mobile phone can be stably kept in the unfolded state or the folded state, the phenomenon that the folding screen mobile phone is loose is avoided, the structure of the folding screen mobile phone is compact, and the folding screen mobile phone is prevented from being closed or unfolded incompletely.
As described above, the first magnetic member 210 and the second magnetic member 310 are magnetically matched, specifically, the first magnetic member 210 and the second magnetic member 310 may be magnetically repulsive, that is, a magnetic pole of the first magnetic member 210 facing the second magnetic member 310 is the same as a magnetic pole of the second magnetic member 310 facing the first magnetic member 210, that is, a magnetic force between the first magnetic member 210 and the second magnetic member 310 is a repulsive force, and in a case where the first rotating portion 200 is located at the third position relative to the second rotating portion 300, the first magnetic member 210 and the second magnetic member 310 may be oppositely disposed in the extending direction of the rotating shaft 100, that is, in a case where the first rotating portion 200 rotates relative to the second rotating portion 300 from the first position to the third position or rotates from the second position to the third position, the first magnetic member 210 is close to the second magnetic member 310.
In a specific rotation process, in the case that the first rotation portion 200 rotates from the first position to the third position or rotates from the second position to the third position with respect to the second rotation portion 300, the magnetic repulsive force between the first magnetic member 210 and the second magnetic member 310 provides damping for the first rotation portion 200, and when the first rotation portion 200 gradually rotates to the third position, the magnetic repulsive force gradually increases; when the first rotating portion 200 rotates from the third position to the first position or rotates from the third position to the second position with respect to the second rotating portion 300, the magnetic repulsive force between the first magnetic member 210 and the second magnetic member 310 drives the first rotating portion 200 to rotate, and when the first rotating portion 200 gradually rotates to the first position or the second position, the magnetic repulsive force gradually decreases. The hinge has a simple structure and is reliable in rotation, and meanwhile, the magnetic repulsion force between the first magnetic part 210 and the second magnetic part 310 cannot disappear due to repeated use of the hinge, so that the hinge is prevented from being loosened after being used for multiple times, and the service life of the hinge can be prolonged.
Alternatively, the first magnetic member 210 and the second magnetic member 310 may also be magnetically attracted, that is, a magnetic pole of the first magnetic member 210 facing the second magnetic member 310 is opposite to a magnetic pole of the second magnetic member 310 facing the first magnetic member 210, that is, the magnetic force between the first magnetic member 210 and the second magnetic member 310 is an attraction force, and when the first rotating portion 200 rotates from the first position to the third position or rotates from the second position to the third position with respect to the second rotating portion 300, the first magnetic member 210 is away from the second magnetic member 310, that is, when the first rotating portion 200 is located at the first position or the second position with respect to the second rotating portion 300, the first magnetic member 210 and the second magnetic member 310 may be disposed opposite to each other in the extending direction of the rotating shaft 100.
In a specific rotating process, when the first rotating portion 200 rotates from the first position to the third position or rotates from the second position to the third position with respect to the second rotating portion 300, since the first magnetic member 210 is gradually far away from the second magnetic member 310, the magnetic attraction force between the first magnetic member 210 and the second magnetic member 310 provides damping for the first rotating portion 200, and when the first rotating portion 200 gradually rotates to the third position, the magnetic attraction force gradually decreases; when the first rotating portion 200 rotates from the third position to the first position or rotates from the third position to the second position with respect to the second rotating portion 300, the magnetic attraction force between the first magnetic member 210 and the second magnetic member 310 drives the first rotating portion 200 to rotate, and when the first rotating portion 200 gradually rotates to the first position or the second position, the magnetic attraction force gradually increases. Similarly, the hinge has a simple structure and is reliable in rotation, and meanwhile, the magnetic attraction force between the first magnetic element 210 and the second magnetic element 310 does not disappear due to the repeated use of the hinge, so that the hinge is prevented from being loosened after the repeated use, and the service life of the hinge can be prolonged.
Specifically, the first magnetic member 210 may be an arc-shaped magnetic member, and the arc-shaped magnetic member extends in the rotation direction of the first rotation portion 200, so that the magnetic matching area between the first magnetic member 210 and the second magnetic member 310 is large, and in the process of rotating the first rotation portion 200 relative to the second rotation portion 300, the first magnetic member 210 and the second magnetic member 310 are beneficial to providing stable and regular magnetic attraction or magnetic repulsion for the first rotation portion 200, so that the hinge can be stably switched between the folded state and the unfolded state, and the stability of the hinge is further improved.
Optionally, the second magnetic member 310 may also be an arc-shaped magnetic member, and the arc-shaped magnetic member extends in the rotation direction of the first rotation portion 200, so that the region where the second magnetic member 310 is magnetically matched with the first magnetic member 210 is relatively large, and in the process that the first rotation portion 200 rotates relative to the second rotation portion 300, the first magnetic member 210 and the second magnetic member 310 are beneficial to providing stable and regular magnetic attraction or magnetic repulsion for the first rotation portion 200, so that the hinge can be stably switched between the folded state and the unfolded state, and further the stability of the hinge is improved.
Further, the first magnetic member 210 and the second magnetic member 310 may be arc-shaped magnetic members, so as to further enable the hinge to be stably switched between the folded state and the unfolded state, and further improve the stability of the hinge. The arc-shaped magnetic member may be a half ring, such as a quarter ring and a half ring, but the arc-shaped magnetic member may not be a full ring, that is, the arc-shaped magnetic member may not form a closed ring.
As described above, the first rotating portion 200 is provided with the first magnetic member 210, the second rotating portion 300 is provided with the second magnetic member 310, and the first rotating portion 200 is provided with a plurality of positions for disposing the first magnetic member 210, for example, a side of the first rotating portion 200 facing away from the second rotating portion 300, or a side wall of the first rotating portion 200, and of course, the second rotating portion 300 is provided with a plurality of positions for disposing the second magnetic member 310, for example, a side of the second rotating portion 300 facing away from the first rotating portion 200, or a side wall of the second rotating portion 300, which is not limited in the embodiment of the present application.
Alternatively, in the extending direction of the rotating shaft 100, a side of the first rotating part 200 facing the second rotating part 300 may be provided with the first magnetic member 210, and a side of the second rotating part 300 facing the first rotating part 200 may be provided with the second magnetic member 310. Because the side of the first rotating part 200 facing the second rotating part 300 is closer to the second rotating part 300, and the side of the second rotating part 300 facing the first rotating part 200 is closer to the first rotating part 200, the distance between the first magnetic member 210 and the second magnetic member 310 can be smaller by the arrangement, so that the magnetic force between the first magnetic member 210 and the second magnetic member 310 can be larger, and a stronger damping feeling can be provided for the hinge. Meanwhile, under the condition that the magnetic force between the first magnetic member 210 and the second magnetic member 310 is the same, the volumes of the first magnetic member 210 and the second magnetic member 310 can be set to be smaller, so that the setting cost of the first magnetic member 210 and the second magnetic member 310 can be saved, the size of the hinge can be smaller, and the hinge is favorable for being installed on electronic equipment.
Specifically, in the extending direction of the rotating shaft 100, a first mounting groove 220 may be formed on one side of the first rotating portion 200 facing the second rotating portion 300, a second mounting groove 320 may be formed on one side of the second rotating portion 300 facing the first rotating portion 200, the first magnetic element 210 may be located in the first mounting groove 220, and the second magnetic element 310 may be located in the second mounting groove 320. The first mounting groove 220 can provide a mounting space for the first magnetic member 210, and the second mounting groove 320 can provide a mounting space for the second magnetic member 310, so that the volumes of the first rotating part 200 and the second rotating part 300 can be effectively reduced, and further, the volume of the hinge can be reduced, so that the hinge has a small size, and further, the hinge is convenient to mount on an electronic device.
Further, the first magnetic members 210 are all located in the first mounting groove 220, and the second magnetic members 310 are all located in the second mounting groove 320, so that the first magnetic members 210 are prevented from protruding out of the first mounting groove 220, and the second magnetic members 310 are prevented from protruding out of the second mounting groove 320, and therefore, when the first rotating portion 200 rotates relative to the second rotating portion 300, the first magnetic members 210 and the second magnetic members 310 are prevented from interfering.
The first rotating portion 200 and the second rotating portion 300 may be worn seriously after being used for a long time, which results in the reduction of the assembling precision of the hinge and further causes the structure of the hinge to be not compact enough, so that the hinge is easy to be loosened. Based on this, in an alternative embodiment, in the extending direction of the rotating shaft 100, a gap may be formed between the first rotating portion 200 and the second rotating portion 300, and the gap can prevent the first rotating portion 200 and the second rotating portion 300 from being worn seriously after being used for a long time, and prevent the assembling precision of the hinge from being reduced, so that the structure of the hinge is compact, the hinge is prevented from being loosened, and the stability of the hinge is further improved.
In the embodiment of the present application, the first magnetic member 210 and the second magnetic member 310 may be electromagnets, but the electromagnets need to be powered on to have magnetic force, and the configuration process of powering on the electromagnets on the hinge is inconvenient, and the wiring is complicated, which may result in a complicated structure and high cost of the hinge. Based on this, in an optional embodiment, the first magnetic member 210 and the second magnetic member 310 may be both permanent magnets, and compared with an electromagnet, the permanent magnets do not need to be electrified, so that the first magnetic member 210 and the second magnetic member 310 can be prevented from being electrified, and an electrical connection line can be prevented from being arranged on the hinge, and meanwhile, the cost of the permanent magnets is low, so that the cost of the hinge can be reduced.
In an alternative embodiment, the first rotating part 200 may include a first rotating body 230 and a first connecting part 240 connected to the first rotating body 230, the second rotating part 300 may include a second rotating body 330 and a second connecting part 340 connected to the second rotating body 330, and both the first connecting part 240 and the second connecting part 340 may be connected to an external part (e.g., a first folding part and a second folding part of a folding screen mobile phone). The first connecting portion 240 and the second connecting portion 340 can facilitate connection of external components and the hinge, so that the hinge can be installed highly, the hinge can be applied to various products (such as a rotary camera and a folding screen mobile phone) conveniently, and product competitiveness of the hinge is improved.
