Description
Technical Field
The invention relates to the technical field of intelligent terminals, in particular to a magnetomotive slide rail device and an intelligent terminal.
Background
As a guide mechanism, a slide rail is widely used in some devices and products with a guide device, especially in a slide-type intelligent terminal, such as a slide-type mobile phone, and the slide rail has various structural forms, which can be mainly classified into the following types according to the type of power:
1. the unpowered sliding rail pushes the guide rail to move through manual or mechanical force;
2. the motor-driven sliding rail converts electric energy into mechanical energy through a motor to drive the sliding rail to move;
3. the spring type slide rail converts elastic potential energy into mechanical energy through a spring to drive the slide rail to move;
4. the magnetic power slide rail converts magnetic energy into mechanical energy through a magnet to drive the slide rail to move;
in the design of a reciprocating sliding mobile phone, the four schemes are applied, but each scheme has different advantages and disadvantages.
1. When the unpowered sliding rail is designed in a mobile phone, the structure is simple, the occupied space is small, the sliding mobile phone can be made to be the thinnest, but the sliding mobile phone with the unpowered sliding rail has poor hand feeling when sliding, the sliding rail is kept in an open or closed state without locking force, the sliding rail is easy to loosen, and the experience is poor.
2. The motor-driven sliding rail needs to be provided with a special motor to drive the sliding rail, so that the structure is complex, the occupied space is large, the thickness of the mobile phone is increased, and the motor cost is high.
3. Spring type slide rail is a slide rail form that uses more at present. The disadvantage is the high requirements on the life of the spring. After the slide rail slides for many times, the elastic force of the spring can be attenuated, and even the spring fails.
4. The magnetic power slide rail has the advantages of simple structure, low price and small occupied space. The outstanding advantages are that the power of the slide rail is hardly lost in the whole service cycle, and the magnets are not in contact with each other, so that the service life is greatly prolonged. Another advantage is that the magnitude of the magnetic force can be easily simulated, so that it becomes very simple for the designer to adjust the thrust of the slide rail.
However, the conventional scheme of the magnetic power slide rail has disadvantages, and referring to fig. 1, the scheme of the magnetic power slide rail in the prior art adopts a principle that the thickness direction is mutually exclusive to drive, and the driving force is not completely parallel to the sliding direction, which causes the loss of the driving force, so that the volume of the magnet is required to be larger, and the sliding hand feeling is not ideal because a mutually exclusive force is always in the thickness direction.
Therefore, there is a need to develop a magnetomotive slide rail device having no driving force loss and good sliding hand feeling, and an intelligent terminal having the same.

Specifically, referring to fig. 2 and 3, the magnetic power slide rail device according to an embodiment of the present invention includes:

The first sliding portion 10 is a rectangular flat plate, and first magnetic portions 11 are disposed on both sides of the first sliding portion 10.
Second sliding part 20
The second sliding portion 20 is also a rectangular flat plate, preferably, the first sliding portion 10 and the second sliding portion 20 have approximately the same size, the second magnetic portion 21 and the third magnetic portion 22 are disposed on both sides of the second sliding portion 20, the second magnetic portion 21 and the third magnetic portion 22 on the same side are coaxially disposed, and the distance between the second magnetic portion 21 and the third magnetic portion 22 is greater than the length of the first magnetic portion 11.
The second sliding portion 20 is mounted on the first sliding portion 10, the first magnetic portion 11 is located between the second magnetic portion 21 and the third magnetic portion 22, and the first magnetic portion 11 is coaxially disposed with the second magnetic portion 21 and the third magnetic portion 22. Since the distance between the second magnetic part 21 and the third magnetic part 22 is greater than the length of the first magnetic part 11, the first magnetic part 11 can move back and forth between the second magnetic part 21 and the third magnetic part 22, that is, the first sliding part 10 and the second sliding part 20 can slide relatively, and the sliding distance is the difference between the distance between the second magnetic part 21 and the third magnetic part 22 and the length of the first magnetic part 11.
In this embodiment, the first magnetic part 11, the second magnetic part 21 and the third magnetic part 22 are all permanent magnets, as shown in fig. 3, the first magnetic part 11 is located between the second magnetic part 21 and the third magnetic part 22, the magnetic poles of the opposite ends of the first magnetic part 11 and the second magnetic part 21 are opposite, and the magnetic poles of the opposite ends of the first magnetic part 11 and the third magnetic part 22 are opposite. Specifically, one end of the first magnetic part 11 facing the second magnetic part 21 is an S pole, and one end of the second magnetic part 21 facing the first magnetic part 11 is an N pole; an end of the first magnetic part 11 facing the third magnetic part 22 is an N-pole, and an end of the third magnetic part 22 facing the first magnetic part 11 is an S-pole. Therefore, the second magnetic part 21 and the third magnetic part 22 both generate magnetic attraction force on the first magnetic part 11, and preferably, the second magnetic part 21 and the third magnetic part 22 are made of the same material and have the same size for providing magnetic attraction force with the same size.
Referring to fig. 4, when the first magnetic part 11 is located near the second magnetic part 21, the magnetic attraction force F1 between the first magnetic part 11 and the second magnetic part 21 is greater than the magnetic attraction force F2 between the first magnetic part 11 and the third magnetic part 22, the first sliding part and the second sliding part are located at the first relative position, and the slide rail device is located in the first state. It should be noted that the approach referred to herein may be close (not directly, with a certain distance) or direct contact, depending on whether there is a stop or a buffer. Under the condition that no other limiting structure or buffer device is arranged, the first magnetic part 11 and the second magnetic part 21 are attracted when the slide rail device is in the first state.
Referring to fig. 5, when an external force is applied to the first sliding portion 10 and the second sliding portion 20 to make them relatively slide along the axial direction of the first magnetic portion 11, the second magnetic portion 21, and the third magnetic portion 22, so that the first magnetic portion 11 is located at a position close to the third magnetic portion 22, the magnetic attraction force F2 between the first magnetic portion 11 and the third magnetic portion 22 is greater than the magnetic attraction force F1 between the first magnetic portion 11 and the second magnetic portion 21, the first sliding portion and the second sliding portion are located at a second relative position, and the slide rail apparatus is located at a second state. Under the condition that no other limiting structure or buffer device is arranged, when the slide rail device is in the second state, the first magnetic part 11 and the third magnetic part 22 are attracted.
Referring to fig. 6, when the first magnetic part 11 is located at the middle position between the second magnetic part 21 and the third magnetic part 22, the magnetic attraction force F1 between the first magnetic part 11 and the second magnetic part 21 is equal to the magnetic attraction force F2 between the first magnetic part 11 and the third magnetic part 22, the first sliding part and the second sliding part are located at the third relative position, and the slide rail device is located at the third state. At this time, when an external force is applied to move the first magnetic part 11 toward the second magnetic part 21, the magnetic attraction force F1 between the first magnetic part 11 and the second magnetic part 21 is greater than the magnetic attraction force F2 between the first magnetic part 11 and the third magnetic part 22, so that the slide rail apparatus enters the first state; when an external force is applied to move the first magnetic part 11 toward the third magnetic part 22, the magnetic attraction force F2 between the first magnetic part 11 and the third magnetic part 22 is greater than the magnetic attraction force F1 between the first magnetic part 11 and the second magnetic part 21, so that the slide rail apparatus enters the second state.
Referring to fig. 2 and 3, in the present embodiment, a position-limiting portion 14 is disposed on the first sliding portion 10, and the position-limiting portion 14 is used to limit the first sliding portion 10 and the second sliding portion 20 to slide only along the axial direction of the first magnetic portion 11, the second magnetic portion 21, and the third magnetic portion 22. The limiting portion 14 is a guide rail disposed on two sides of the first sliding portion 10, the guide rail is overlapped or parallel to the axes of the first magnetic portion 11, the second magnetic portion 21, and the third magnetic portion 22, and accordingly, two side edges of the second sliding portion 20 extend into the guide rail. Specifically, the guide rail is a folded edge bent inward from the side edge of the first sliding portion 10, and is approximately in an inverted L shape, and the corner of the folded edge is in arc transition. The two side edges of the second sliding portion 20 extend into the position-limiting portions 14 on the two sides of the first sliding portion 10, and the position-limiting portions 14 limit the second sliding portion 20 to slide relative to the first sliding portion 10 only along the axial direction of the first magnetic portion 11, the second magnetic portion 21, and the third magnetic portion 22, but not along the direction perpendicular to the first sliding portion 10. Preferably, the side of the second sliding part 20 is shaped to match the shape of the inside of the hem, so that the two can be more closely combined; further, be provided with the self-lubricating material layer between the side of second sliding part 20 and the guide rail, the self-lubricating material layer is fixed in on the side of second sliding part 20 or is fixed in the guide rail inboard through some glue or the mode of moulding plastics in the mould for frictional resistance when reducing to slide. The self-lubricating material layer can be POM engineering plastic or other suitable solid self-lubricating materials. In some embodiments, the limiting portion 14 may also be disposed on the second sliding portion 20, and the structure and principle thereof are similar to those of the present embodiment, and are not described herein again.
Referring to fig. 2, in this embodiment, a sliding slot 12 is disposed on the first sliding portion 10, a sliding block 13 is disposed in the sliding slot 12, a flexible protruding portion is disposed on the sliding block 13, and the protruding portion is disposed on the sliding block 13 and faces to two sides of an end of the sliding slot 12, so as to play a role of buffering when the sliding block 13 slides to the end of the sliding slot 12, on one hand, to slow down the impact between the sliding block 13 and the sliding slot 12, avoid damage caused by the impact, and prolong the service life of the sliding block 13 and the sliding slot 12; on the other hand, the sound generated when the sliding block 13 collides with the sliding groove 12 is reduced, and the use experience of the user is improved. Preferably, the flexible convex part is made of TPU. The sliding block 13 can only slide in the sliding groove 12; the distance that the slider 13 slides in the slide groove 12 is smaller than the difference between the distance between the second magnetic part 21 and the third magnetic part 22 and the length of the first magnetic part 11. The direction of the sliding groove 12 is parallel to the axial direction of the first magnetic part 11, the second magnetic part 21 and the third magnetic part 22. Meanwhile, the sliding block 13 is fixedly connected with the second sliding portion 20, so that when the first sliding portion 10 slides relative to the second sliding portion 20, the second sliding portion 20 drives the sliding block 13 to move synchronously in the sliding groove 12. Specifically, in the present embodiment, a screw is disposed on the slider, a screw hole 23 is correspondingly disposed on the second sliding portion 20, and the slider 13 and the second sliding portion 20 are fixedly connected by the threaded engagement of the screw and the screw hole 23. In some embodiments, the sliding block 13 and the second sliding portion 20 are fixedly connected by spot welding. The sliding grooves 12 and the sliding blocks 13 are used for limiting the relative sliding distance of the first sliding part 10 and the second sliding part 20. Since the sliding distance of the sliding block 13 in the sliding slot 12 is smaller than the difference between the distance between the second magnetic part 21 and the third magnetic part 22 and the length of the first magnetic part 11, it can be defined that when the slide rail device is in the first state, the first magnetic part 11 and the second magnetic part 21 are not in direct contact, but keep a certain distance, and when the slide rail device is in the second state, the first magnetic part 11 and the third magnetic part 22 are not in direct contact, but keep a certain distance. Through the arrangement, when the slide rail device is switched between the first state and the second state, the first magnetic part 11, the second magnetic part 21 and the third magnetic part 22 directly collide to cause damage, so that the service lives of the first magnetic part 11, the second magnetic part 21 and the third magnetic part 22 can be prolonged, and the slide rail device can stably work for a long period. In some embodiments, the sliding groove 12 and the sliding block 13 may be disposed on the second sliding portion 20, and the sliding block 13 and the first sliding portion 10 are fixedly connected and move synchronously. And will not be described in detail herein.
In some embodiments, instead of the sliding groove 12 and the sliding block 13, a buffer member for avoiding direct impact may be disposed between the first magnetic part 11 and the second magnetic part 21, and the buffer member is fixedly connected to an end of the first magnetic part 11 or the second magnetic part 21; meanwhile, a buffer member for avoiding direct impact is also arranged between the first magnetic part 11 and the third magnetic part 22, and the buffer member is fixedly connected to the end of the first magnetic part 11 or the third magnetic part 22. The cushioning member may preferably be a rubber cushion. The buffer member may be fixedly connected to an end of the first magnetic part 11, the second magnetic part 21 or the third magnetic part 22 by gluing. Through the arrangement of the buffer component, when the slide rail device is switched between the first state and the second state, the first magnetic part 11, the second magnetic part 21 and the third magnetic part 22 can be prevented from directly colliding to cause damage to the first magnetic part 11, the second magnetic part 21 and the third magnetic part 22, so that the service lives of the first magnetic part 11, the second magnetic part 21 and the third magnetic part 22 can be prolonged, and the slide rail device can stably work for a long period. Meanwhile, the buffer component can reduce the sound generated when the sliding rail device is switched between the first state and the second state, and the use experience of a user is improved. It should be noted that in this embodiment, the coupling force between the first magnetic part 11 and the second magnetic part 21 needs to be properly adjusted to provide the slide rail device with a good sliding feel. In some embodiments, the buffering member may not be provided, and the first magnetic part 11 and the second magnetic part 21 or the third magnetic part 22 are in direct contact.
Further, with the slide rail device in the embodiment of fig. 2, the first sliding portion 10 and the second sliding portion 20 are approximately the same size, so that when the slide rail device is in the first state, the first sliding portion 10 and the second sliding portion 20 are approximately overlapped, so that the surface of the first sliding portion 10 facing the second sliding portion 20 and the surface of the second sliding portion 20 facing the first sliding portion 10 are shielded from view. When the slide rail device is in the second state, the first sliding portion 10 and the second sliding portion 20 are staggered by a certain position, that is, a part of one surface of the first sliding portion 10 facing the second sliding portion 20 and a part of one surface of the second sliding portion 20 facing the first sliding portion 10 are exposed and visible. Thus, we can define the first state as the off state and the second state as the on state. Preferably, the first sliding part 10 or the second sliding part 20 is provided with a component to be exposed, and the difference between the distance between the second magnetic part 21 and the third magnetic part 22 and the length of the first magnetic part 11 is greater than or equal to the length of the component to be exposed; when the slide rail device is in a first state, the component to be exposed is shielded; when the slide rail device is in the second state, the part to be exposed is exposed. Specifically, for example, when the slide rail device is applied to a smart phone, the second sliding portion 20 located at the upper portion may be a first phone portion including a screen, and the first sliding portion 10 located at the lower portion may be a second phone portion including a battery and the like, and in order to implement a full-screen design, a front camera module, i.e., the exposed portion, may be disposed on the first sliding portion 10 on a side facing the second sliding portion 20. When the slide rail device is in a first state, namely a closed state, the second sliding portion 20 shields the front camera module on the first sliding portion 10 to make it invisible, and when the slide rail device is in a second state, namely an open state, the second sliding portion 20 and the first sliding portion 10 are staggered by a certain position to expose the front camera module, so that the front camera module works in the second state to realize the function. Through such design, can realize the design of full face screen, make the screen keep intact and have great display area, and need not reduce the display area of screen or carry out the trompil on the screen in order to set up leading camera module. In some embodiments, the to-be-exposed component may be a keyboard module, the keyboard module is hidden when the slide rail device is in a first state, namely, a closed state, and is exposed when the slide rail device is in a second state, namely, an open state, so that when the slide rail device is applied to an intelligent terminal such as a smart phone, a full keyboard can be implemented in the intelligent terminal, and the input of a user is facilitated. The belt exposure component is not limited to the front camera module or the keyboard module, and can be other suitable components. The exposed part is arranged in the sliding rail device, so that the application scenes of the sliding rail device are greatly enriched.
In the embodiment of fig. 2, the first magnetic part 11, the second magnetic part 21 and the third magnetic part 22 are all permanent magnets. In some embodiments, the first magnetic part 11, the second magnetic part 21 and the third magnetic part 22 may be electromagnets. The electromagnet has the advantages that the direction of the magnetic field and the strength of the magnetic field can be changed by changing the electrifying direction and the current strength, so that the automatic sliding of the sliding rail is realized, and the sliding direction and speed can be adjusted. Specifically, taking fig. 3 as an example, when the first magnetic part 11, the second magnetic part 21 and the third magnetic part 22 are all electromagnets, the slide rail device is in the first state, an end of the first magnetic part 11 facing the second magnetic part 21 is an S pole, and an end of the second magnetic part 21 facing the first magnetic part 11 is an N pole; an end of the first magnetic part 11 facing the third magnetic part 22 is an N-pole, and an end of the third magnetic part 22 facing the first magnetic part 11 is an S-pole. By changing the direction of the current flowing into the second magnetic part 21, the end of the second magnetic part 21 facing the first magnetic part 11 is changed from N-level to S-level, and the second magnetic part 21 generates a repulsive force to the first magnetic part 11 to push the first magnetic part 11 to move towards the third magnetic part 22, further, the current flowing into the second magnetic part 21 can be increased, so that the repulsive force is increased to further push the first magnetic part 11 to move towards the third magnetic part 22 until the slide rail device is in the second state. Therefore, when the first magnetic part 11, the second magnetic part 21 and the third magnetic part 22 are electromagnets, the direction and the magnitude of the current are changed, so that the slide rail can be automatically switched between the first state and the second state without applying external force, and the slide rail can be applied to some automatic lifting devices. On the other hand, for the magnetic power slide rail of the slide phone in the prior art, the permanent magnet is used, the magnetic force is fixed, and a user can only adapt to the magnetic power slide rail when using the magnetic power slide rail, and can not change the use habit of the user to freely adjust the magnetic power slide rail.
