Description

Functional components and mobile terminals

Technical Field

This application relates to the field of electronic devices, and more particularly to a functional component and a mobile terminal.

Background Technology

Currently, mobile phone components provide users with functionalities. However, these components increase the size of the phone, causing inconvenience in carrying or holding it, thus reducing the user experience.

Summary of the Invention

This application provides a functional component and mobile terminal for improving user experience.

This application provides a functional component, including a base, a drive assembly, a sliding seat, and a functional device. The base has a receiving cavity, and the drive assembly is housed in the receiving cavity. The drive assembly includes a motor, a lead screw, and a slider. The lead screw is connected to the rotating shaft of the motor, and the slider is sleeved on the lead screw. The sliding seat is slidably connected to the base, and the functional device is housed in the sliding seat. A magnetic attraction force is generated between the slider and the sliding seat. When the rotating shaft drives the lead screw to rotate, the slider drives the sliding seat to move relative to the base, so that the functional device extends out of or retracts into the receiving cavity.

This application also provides a mobile terminal, including the above-mentioned functional components.

In the functional components and mobile terminal provided in this application, the sliding seat can move with the slider due to the magnetic attraction between the slider and the sliding base. When the motor's shaft rotates, it drives the lead screw to rotate, thereby causing the slider sleeved on the lead screw to move, which in turn drives the sliding seat to move relative to the base, allowing the functional device to extend out of or retract into the receiving cavity. When the functional device extends out of the receiving cavity, it ensures interaction between the functional device and the user. When the functional device retracts into the receiving cavity, it reduces the size of the mobile terminal, making it easier for the user to carry. Therefore, the functional components and mobile terminal improve the user experience. Since the slider and the sliding base are connected by magnetic attraction, there is no rigid connection between them. Therefore, if the functional device is subjected to an impact force towards the base, the sliding seat will quickly overcome the magnetic attraction and detach from the slider, allowing the sliding seat to carry the functional device into the receiving cavity. This avoids damage to the functional device due to rigid impact, resulting in high reliability of the functional components and the mobile terminal.

Please refer to Figures 1 to 3. This application embodiment provides a functional component 100. The functional component 100 includes a base 1, a drive component 2, a sliding seat 3, and a functional device 4. The base 1 has a receiving cavity 10. The drive component 2 is housed in the receiving cavity 10. The drive component 2 includes a motor 21, a lead screw 22, and a slider 23. The lead screw 22 is connected to the rotating shaft of the motor 21 (not shown in the figure). The slider 23 is sleeved on the lead screw 22. The sliding seat 3 is slidably connected to the base 1. The functional device 4 is housed in the sliding seat 3. A magnetic attraction is generated between the slider 23 and the sliding seat 3. Please refer to Figures 1 to 5. When the rotating shaft drives the lead screw 22 to rotate, the slider 23 drives the sliding seat 3 to move relative to the base 1, so that the functional device 4 extends out of or retracts into the receiving cavity 10. The functional device 4 can be any one or more combinations of a camera module, iris recognition module, face recognition module, flash, microphone, receiver, photosensor, fingerprint module, buttons, etc. It is understood that, referring to Figure 6, the functional component 100 can be applied to a mobile terminal 200. This mobile terminal 200 can be a mobile phone, tablet computer, laptop computer, etc.

In this embodiment, due to the magnetic attraction between the slider 23 and the sliding seat 3, the sliding seat 3 can move with the slider 23. When the shaft of the motor 21 rotates, it drives the lead screw 22 to rotate, thereby causing the slider 23 sleeved on the lead screw 22 to move, which in turn drives the sliding seat 3 to move relative to the base 1, allowing the functional device 4 to extend out of or retract into the receiving cavity 10. When the functional device 4 of the functional component 100 extends out of the receiving cavity 10, it ensures that the functional device 4 can interact with the user. When the functional device 4 retracts into the receiving cavity 10, it reduces the size of the mobile terminal 200, making it easier for the user to carry the mobile terminal 200. Therefore, the functional component 100 improves the user experience. Since the slider 23 and the sliding seat 3 are connected to each other by magnetic attraction, and there is no rigid connection between the slider 23 and the sliding seat 3, if the functional device 4 is subjected to an impact force that impacts the base 1, the sliding seat 3 will quickly overcome the magnetic attraction and detach from the slider 23, so that the sliding seat 3 carries the functional device 4 into the receiving cavity 10. This can prevent the functional device 4 from being damaged by rigid impact, and make the functional component 100 and the mobile terminal 200 more reliable.

Optionally, the motor 21 may be a stepper motor or other servo motor capable of precise control, so as to accurately control the movement stroke of the sliding seat 3 through the slider 23, thereby improving the user experience and reliability of the functional component 100 and the mobile terminal 200. The motor 21 is fixed on the base 1.

Optionally, the slider 23 is screwed onto the lead screw 22. Specifically, the outer surface of the lead screw 22 is provided with a helical groove. The slider 23 is provided with a through hole, and a limiting block is provided on the wall of the through hole. The slider 23 is sleeved on the outer surface of the lead screw 22, and the limiting block is received in the helical groove to move along the helical groove. In other embodiments, the outer surface of the lead screw may be provided with an external thread, and the wall of the through hole may be provided with an internal thread, with the internal thread and the external thread screwed together.

Optionally, referring to Figures 2, 3, and 5, the sliding seat 3 includes a base 31 and a driving block 32. The base 31 supports the functional device 4. The driving block 32 is fixed to the base 31 and faces the slider 23, and a magnetic attraction is generated between the slider 23 and the driving block 32. The driving block 32 can be fixed to the base 31 by means of snap-fit connection, fastener connection, bonding, or welding.

In one embodiment, both the slider 23 and the driving block 32 are made of permanent magnet materials, and the magnetic properties of the driving block 32 are opposite to those of the slider 23. The driving block 32 and the slider 23, with their opposite magnetic properties, generate a magnetic attraction force, attracting each other. This allows the driving block 32 and the sliding seat 3 to move by moving the slider 23. Permanent magnet materials, also known as "hard magnetic materials," refer to materials that maintain constant magnetism once magnetized. Permanent magnet materials include, but are not limited to, AlNiCo permanent magnet alloys, IronChromiumCo permanent magnet alloys, permanent magnet ferrites, rare earth permanent magnet materials, and composite permanent magnet materials.

In another embodiment, the slider 23 is made of a permanent magnet material, and the drive block 32 is made of a ferromagnetic material. Ferromagnetic materials include, but are not limited to, iron, cobalt, nickel, and gadolinium. The substrate 31 is made of a non-ferromagnetic material. In this case, a magnetic attraction is generated between the slider 23 and the drive block 32, and the slider 23 attracts the drive block 32, thereby enabling the drive block 32 and the sliding seat 3 to move by moving the slider 23. The substrate 31 is made of a non-ferromagnetic material, so it is not attracted by the slider 23, thus avoiding interference with the magnetic attraction between the slider 23 and the drive block 32, allowing the slider 23 to accurately control the movement of the drive block 32.

Optionally, referring to Figures 2 and 5, a gap is formed between the slider 23 and the driving block 32. When the functional device 4 is subjected to an impact force towards the base 1, the gap prevents the slider 23 from hitting the driving block 32 and allows the sliding seat 3 to overcome the magnetic attraction and detach from the slider 23 more quickly. This allows the sliding seat 3 to carry the functional device 4 into the receiving cavity 10, preventing the functional device 4 from being damaged by rigid impact, thus improving the reliability of the functional component 100 and the mobile terminal 200. Further, the gap is less than or equal to 1 mm. In this case, the magnetic attraction between the slider 23 and the driving block 32 ensures that the slider 23 can smoothly move the sliding seat 3 through the driving block 32.

Optionally, referring to Figures 3 and 7, the number of driving components 2 is two sets, with the two sets of driving components 2 located on opposite sides of the base 31. The number of driving blocks 32 is two, with the two driving blocks 32 respectively embedded on two opposite sides 312 of the base 31, and the two driving blocks 32 are arranged facing the sliders 23 of the two sets of driving components 2 in a one-to-one correspondence.

In this embodiment, the two sets of drive components 2 can move the two drive blocks 32 simultaneously through the two sliders 23, thereby moving the sliding seat 3 quickly and accurately, making the action of the functional component 100 extending out of the receiving cavity 10 and retracting into the receiving cavity 10 faster, more accurate and reliable.

The two sets of drive components 2 and the sliding base 3 are arranged in the planar direction of the mobile terminal 200 (that is, in the direction perpendicular to the thickness direction of the mobile terminal 200) to avoid increasing the thickness of the mobile terminal 200 and to facilitate the thinning of the mobile terminal 200.

Optionally, referring to Figures 2, 3, and 5, the substrate 31 includes a bottom 311 and a side portion 312 surrounding the bottom 311. The bottom 311 and the side portion 312 together enclose a device space 310. The functional device 4 is housed in the device space 310. The sliding seat 3 also includes a cover plate 33, which connects to the side portion 312 to cover the device space 310. The cover plate 33 has a signal penetration portion 331 facing the functional device 4.

In this embodiment, the cover plate 33 and the base 31 together surround the functional device 4, thereby providing protection. The signal penetration part 331 provided on the cover plate 33 enables smooth interaction with the user when the functional device 4 extends out of the receiving cavity 10.

In one embodiment, the functional device 4 includes a camera module, and/or an iris recognition module, and/or a face recognition module, and/or a fingerprint recognition module, and/or a flash, and/or a photosensor. The signal penetration portion 331 is a light-transmitting lens or a light-transmitting hole. The signal penetration portion 331 allows light signals to pass through. For example, the functional device 4 can be a front-facing camera module. The functional device 4 acquires images of the scene to be photographed in a direction away from the bottom 311. The signal penetration portion 331 of the cover plate 33 is a light-transmitting hole. The cover plate 33 protects the functional device 4 and provides a darkroom environment for the functional device 4 to facilitate its shooting.

In another embodiment, the functional device 4 includes a receiver and/or a transmitter, and the signal penetration portion 331 is a perforated plate or a through hole. The signal penetration portion 331 is used to allow sound signals to pass through.

In another embodiment, there are multiple functional devices 4 and multiple signal penetration sections 331. Each of the multiple signal penetration sections 331 is directly opposite to the multiple functional devices 4 and is adapted to the signal type received or released by the multiple functional devices 4.

Optionally, referring to Figures 2 and 5, the base 1 includes a base plate 11 and a frame 12 connecting the periphery of the base plate 11. The frame 12 has a telescopic opening 121 communicating with the receiving cavity. The sliding seat 3 is slidably connected to the frame 12 via the telescopic opening 121, so that the functional device 4 extends out of or retracts into the receiving cavity 10 via the telescopic opening 121. The base plate 11 may be the back cover of the mobile terminal 200. The frame 12 may be the peripheral frame 12 of the mobile terminal 200.

In this embodiment, the base plate 11 of the base 1 supports the sliding seat 3 and the driving assembly 2 to ensure that the driving assembly 2 can drive the sliding seat 3 to extend and retract relative to the base 1. The motor 21 is fixed to the base plate 11. The extension direction of the lead screw 22 is approximately perpendicular to the side of the frame 12 where the telescopic opening 121 is provided, so as to reduce the travel of the slider 23. The frame 12 covers and hides the sliding seat 3 and the driving assembly 2 to improve the appearance and safety performance of the functional component 100. Since the telescopic opening 121 is provided on the frame 12, the functional device 4 extends and retracts on the side of the base 1, that is, the functional device 4 extends and retracts on the side of the mobile terminal 200, and the functional device 4 does not occupy the front space of the mobile terminal 200.

Optionally, referring to Figures 1 to 5, the outer peripheral sidewall of the sliding seat 3 is clearance-fitted with the inner peripheral sidewall of the telescopic opening 121. In this case, the gap between the outer peripheral sidewall of the sliding seat 3 and the inner peripheral sidewall of the telescopic opening 121 ensures that the sliding seat 3 can slide smoothly relative to the base 1.

Optionally, referring to Figures 1 to 5, a sealing ring 34 is fitted around the outer periphery of the side 312 of the sliding seat 3 away from the fixed seat (as shown in Figure 3). When the functional device 4 is retracted into the receiving cavity 10, the sealing ring 34 seals between the outer peripheral sidewall of the sliding seat 3 and the inner peripheral sidewall of the telescopic opening 121. The sealing ring 34 prevents external moisture and dust from entering the receiving cavity 10 through the telescopic opening 121, thereby improving the reliability of the functional device 4 and the mobile terminal 200.

Optionally, referring to Figures 4 and 5, the base plate 11 is provided with a guide groove 111, which connects the receiving cavity 10 and the telescopic opening 121. The sliding seat 3 slides along the guide groove 111. The guide groove 111 is used to cooperate with the telescopic opening 121 to jointly limit the sliding direction of the sliding seat 3, thereby ensuring that the functional device 4 can smoothly extend out of or retract into the receiving cavity 10.

Further, referring to Figures 4 and 5, a gap is formed between the end face 1111 of the guide groove 111 away from the frame 12 and the outer side surface 121 of the frame 12 (i.e., the side away from the base plate 11). The sliding seat 3 has a length dimension in the extending direction of the guide groove 111. The ratio of the gap to the length dimension is greater than or equal to 1 and less than or equal to 1.1.

At this time, the end face 1111 of the guide groove 111 away from the frame 12 can limit the sliding seat 3, restricting the depth of the sliding seat 3 into the receiving cavity 10, and preventing the sliding seat 3 from falling completely into the receiving cavity 10, thereby ensuring the reliability of the functional component 100 and the mobile terminal 200. Furthermore, it can also limit and protect the sliding seat 3 when the functional component 100 is subjected to accidental impact or the functional device 4 is retracted into the receiving cavity 10.

Optionally, referring to Figures 2, 3, and 5, the functional component 100 also includes a flexible printed circuit board (FPC) 5. One end of the flexible circuit board 5 extends into the sliding base 3 and is electrically connected to the functional device 4, while the other end of the flexible circuit board 5 extends out of the sliding base 3. The other end of the flexible circuit board 5 is located within the receiving cavity 10 to electrically connect to other devices located within the receiving cavity 10, such as the motherboard 201 of the mobile terminal 200.

Please refer to Figures 1 to 7. This application also provides a mobile terminal 200. The mobile terminal 200 includes the functional components 100 described in any of the above embodiments. The mobile terminal 200 involved in this application can be any device with communication and storage functions, such as: tablet computers, mobile phones, e-readers, remote controls, personal computers (PCs), laptops, in-vehicle devices, smart TVs, wearable devices, and other intelligent devices with network functions. The mobile terminal 200 also includes a battery 202, a motherboard 201, etc., housed within the accommodating cavity 10.

Optionally, the accommodating cavity 10 has a receiving opening 101 perpendicular to the sliding direction of the functional device 4. The mobile terminal 200 also includes a display module 203, which covers the base 1 and conceals the receiving opening 101. Since the functional device 4 can flexibly extend out of or retract into the accommodating cavity 10 according to usage requirements, the functional device 4 does not need to occupy the front space of the mobile terminal 200 and does not limit the screen ratio of the display module 203, thereby increasing the screen ratio of the mobile terminal 200 and facilitating the development of full-screen display for the mobile terminal 200.

The display module 203 includes a display area 2031 and a border area 2032 surrounding the display area 2031. The ratio of the area of the display area 2031 to the area of the border area 2032 is greater than or equal to 9. In other words, the display area 2031 occupies more than or equal to 90% of the front area of the display module 203. In this case, the display module 203 can achieve full-screen display. The border area 2032 is used to arrange the drive cables to enable the display area 2031 to display the image.

The display module 203 may be a touch display module 203. The display module 203 may be a liquid crystal display (LCD) or an organic light-emitting diode (OLED).

The above are the implementation methods of the embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the embodiments of this application, and these improvements and modifications are also considered to be within the protection scope of this application.
