本申请要求于2022年10月20日提交中国专利局、申请号为202211289354.3、申请名称为“具有柔性银幕的可折叠电子设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。This application claims priority to the Chinese patent application filed with the China Patent Office on October 20, 2022, with application number 202211289354.3 and application name “Foldable electronic device with flexible screen”, the entire contents of which are incorporated by reference in this application.
本申请涉及电子设备技术领域,特别涉及一种具有柔性银幕的可折叠电子设备。The present application relates to the technical field of electronic equipment, and in particular to a foldable electronic device with a flexible screen.
随着柔性屏技术的逐渐成熟,促使电子设备的显示方式发生非常巨大的变化,其中之一就是可折叠手机、电脑等电子设备的出现,可折叠电子设备的柔性屏可根据不同使用场景灵活变化切换模式,同时还具有高的占屏比和清晰度,如以可折叠手机为例,手机折叠后可以只有传统手机大小,方便携带,而展开后却可以有平板的显示尺寸,能够实现大屏显示,这些特点使可折叠设备成为深受人们追捧的产品之一。As flexible screen technology matures, the display mode of electronic devices has undergone tremendous changes. One of them is the emergence of foldable mobile phones, computers and other electronic devices. The flexible screens of foldable electronic devices can flexibly switch modes according to different usage scenarios. At the same time, they have a high screen-to-body ratio and clarity. For example, when the phone is folded, it can be only the size of a traditional phone, which is convenient to carry, and when unfolded, it can have the display size of a tablet, which can achieve large-screen display. These features make foldable devices one of the most popular products.
可折叠的电子设备可以包括有折叠装置、位于折叠装置两侧的两个中框、以及铺设在中框和折叠装置上的柔性显示屏,柔性显示屏用于实现图像等的显示。两个中框之间可以通过折叠装置实现转动配合,使得两个中框能够相对发生转动,进而使两个中框可以相互叠合或展开。当两个中框完全合拢至相互平行时,电子设备处于闭合状态(也称折叠状态),柔性显示屏分别贴附在两个中框上,与折叠装置相对的部分柔性显示屏则弯折位于折叠装置围起来的空间内。当两个中框处于打开状态,柔性显示屏也随之打开,两中框以及折叠装置中相邻两者间大致呈180°(允许存在少许偏差)时,电子设备处于打开状态(也称展平状态),柔性显示屏就平铺在两中框和折叠装置上。然而,柔性显示屏在弯折与打开过程中易发生损伤,或者是在一些撞击、跌落等过程中也易发生损坏,产生黑斑、碎亮点等现象,使电子设备的可靠性较差,且为减小折叠对柔性显示屏的损伤,柔性显示屏的弯折角度要求较大,会导致电子设备厚度较厚。A foldable electronic device may include a folding device, two middle frames located on both sides of the folding device, and a flexible display screen laid on the middle frame and the folding device, and the flexible display screen is used to display images, etc. The two middle frames can be rotated together through the folding device, so that the two middle frames can rotate relative to each other, so that the two middle frames can overlap or unfold each other. When the two middle frames are completely closed and parallel to each other, the electronic device is in a closed state (also called a folded state), and the flexible display screens are respectively attached to the two middle frames, and the part of the flexible display screen opposite to the folding device is bent and located in the space enclosed by the folding device. When the two middle frames are in an open state, the flexible display screen is also opened, and when the two middle frames and the adjacent two in the folding device are approximately 180° (a small deviation is allowed), the electronic device is in an open state (also called a flattened state), and the flexible display screen is laid flat on the two middle frames and the folding device. However, flexible displays are prone to damage during the process of bending and opening, or during some impacts, drops, etc., resulting in black spots, broken bright spots, etc., making the reliability of electronic devices poor. In order to reduce the damage to the flexible display caused by folding, the bending angle of the flexible display is required to be larger, which will make the electronic device thicker.
因此,亟需一种可靠性更好,且更加轻薄的可折叠电子设备。Therefore, there is an urgent need for a foldable electronic device that is more reliable and thinner.
发明内容Summary of the invention
本申请提供一种具有柔性银幕的可折叠电子设备,弯折耐久性强,具有很好的可靠性,可实现更小角度的弯折,有利于电子设备的减薄化设计。The present application provides a foldable electronic device with a flexible screen, which has strong bending durability, good reliability, and can achieve bending at a smaller angle, which is conducive to the thinning design of the electronic device.
本申请提供一种具有柔性银幕的可折叠电子设备,包括至少一个折叠装置和分别位于折叠装置两侧的两个壳体,两个壳体通过折叠装置转动配合,柔性银幕铺设在两个壳体和折叠装置上。The present application provides a foldable electronic device with a flexible screen, comprising at least one folding device and two shells respectively located on both sides of the folding device, the two shells are rotated and matched through the folding device, and the flexible screen is laid on the two shells and the folding device.
还包括投影装置,投影装置设置在两个壳体的其中一个壳体上,投影装置用于形成显示影像,当电子设备处于展平状态时,投影装置用于将显示影像投射至柔性银幕上,实现影像的显示,也就实现了电子设备展开后的大屏显示,以保证电子设备的显示功能。It also includes a projection device, which is arranged on one of the two shells. The projection device is used to form a display image. When the electronic device is in a flat state, the projection device is used to project the display image onto the flexible screen to realize the display of the image, thereby realizing a large-screen display after the electronic device is unfolded to ensure the display function of the electronic device.
柔性银幕仅作为显示影像的载体或成像介质,自身不发光,也无显示功能、触控功能等的需求,其层叠结构较为简单,无需加入具有显示功能、电信号处理功能及触控功能等的镀层,具有较高的可靠性,在随着电子设备的弯折及展开的过程中、或者是碰撞跌落等场景中均不易受到损伤,能够减小或避免出现黑斑、碎亮点等显示不良的问题,在保证电子设备的功能的前提下,显著的提升了电子设备的可靠性。而且柔性银幕成本较低,有利于降低电子设备的生产成本以及更换维护成本。此外,当电子设备处于折叠状态时,柔性银幕的弯折角度要求也相对较小,在不损伤柔性银幕条件下,能够实现更小角度的弯折,有利于减小电子设备的厚度,利于实现电子设备的减薄化设计。The flexible screen is only used as a carrier or imaging medium for displaying images. It does not emit light by itself, and does not require display functions or touch functions. Its laminated structure is relatively simple, and there is no need to add coatings with display functions, electrical signal processing functions, and touch functions. It has high reliability and is not easily damaged during the bending and unfolding of electronic devices, or in scenes such as collisions and falls. It can reduce or avoid poor display problems such as black spots and broken bright spots. Under the premise of ensuring the functions of electronic devices, the reliability of electronic devices is significantly improved. Moreover, the cost of flexible screens is low, which is conducive to reducing the production cost and replacement and maintenance cost of electronic devices. In addition, when the electronic device is in a folded state, the bending angle requirement of the flexible screen is relatively small. Without damaging the flexible screen, a smaller bending angle can be achieved, which is conducive to reducing the thickness of the electronic device and realizing the thinning design of the electronic device.
在一种可能的实现方式中,每个壳体包括本体和位于本体周向外侧的外侧边,柔性银幕铺设在本体上。In a possible implementation, each shell includes a main body and an outer side located on the outer side of the main body in a circumferential direction, and the flexible screen is laid on the main body.
可折叠电子设备还包括投影支架,投影支架设置在外侧边上,投影支架上具有出光口,投影装置的
显示影像通过出光口投射至柔性银幕上,投影支架可以在实现使显示影像投射至柔性银幕上的同时,可以对投影装置等起到保护作用,而且投影支架可以便于实现对显示图像的投影角度、位置等的调节。The foldable electronic device also includes a projection bracket, which is arranged on the outer side and has a light outlet. The display image is projected onto the flexible screen through the light outlet. The projection bracket can protect the projection device while realizing the projection of the display image onto the flexible screen. Moreover, the projection bracket can facilitate the adjustment of the projection angle, position, etc. of the display image.
在一种可能的实现方式中,当电子设备处于展平状态时,出光口位于两个壳体铺设有柔性银幕的一侧上方,出光口位于投影支架上面向柔性银幕的一侧,使出光口与柔性银幕之间具有一定的角度及距离,以便于显示影像从出光口投射至柔性银幕上进行显示。In one possible implementation, when the electronic device is in a flattened state, the light outlet is located above one side of the two shells on which the flexible screen is laid, and the light outlet is located on the side of the projection bracket facing the flexible screen, so that there is a certain angle and distance between the light outlet and the flexible screen, so that the display image is projected from the light outlet to the flexible screen for display.
在一种可能的实现方式中,外侧边上开设有装配槽,投影支架位于装配槽内并与外侧边转动配合,投影支架绕第一方向转动,第一方向与外侧边的长度延伸方向相平行。使投影支架相对本体及其上的柔性银幕能够转动,投影支架转动至不同位置时,会与柔性银幕之间呈不同的倾斜角度,从出光口投射的显示影像的投影角(视场角)在柔性银幕上的位置、投射的角度以及出光口与柔性银幕间的距离等均会发生变化,在柔性银幕上会形成不同显示尺寸、不同显示精度等的显示影像。也就是说,可以通过调整投影支架的旋转角度可以实现对显示影像的显示尺寸、精度等的调节,也就实现了对显示效果的调节,有利于提升显示效果。也可以针对不同的显示场景调整对应的显示效果,进一步提升电子设备的显示功能。In a possible implementation, an assembly groove is provided on the outer side, the projection bracket is located in the assembly groove and rotates with the outer side, and the projection bracket rotates around a first direction, and the first direction is parallel to the length extension direction of the outer side. The projection bracket can rotate relative to the main body and the flexible screen thereon. When the projection bracket rotates to different positions, it will have different inclination angles with the flexible screen. The projection angle (field of view angle) of the display image projected from the light outlet on the flexible screen, the projection angle, and the distance between the light outlet and the flexible screen will all change, and display images with different display sizes and different display precisions will be formed on the flexible screen. In other words, the display size, precision, etc. of the display image can be adjusted by adjusting the rotation angle of the projection bracket, thereby adjusting the display effect, which is beneficial to improving the display effect. The corresponding display effect can also be adjusted for different display scenes to further enhance the display function of the electronic device.
在一种可能的实现方式中,装配槽延伸至本体上,当电子设备处于折叠状态时,投影支架整***于装配槽内,从而通过装配槽可以对投影支架实现容纳隐藏,减小或避免投影支架的设置对处于折叠态时电子设备的体积尺寸及形状等的影响,保证电子设备处于折叠状态时的小体积,以便于存储携带等,也有利于提升电子设备的美观性。In a possible implementation, the assembly groove extends to the main body, and when the electronic device is in a folded state, the projection bracket is entirely located in the assembly groove, so that the projection bracket can be accommodated and hidden through the assembly groove, reducing or avoiding the influence of the setting of the projection bracket on the volume size and shape of the electronic device in the folded state, ensuring the small volume of the electronic device in the folded state, facilitating storage and carrying, etc., and also helping to improve the aesthetics of the electronic device.
出光口位于投影支架上背向柔性银幕的一侧,也即出光口朝向壳体的外侧,在壳体相对的一侧可以设置有成像介质,成像介质可以是任何具有反射光特性的结构件,能够实现显示影像的显示。投影装置可以将形成的显示影像投射至成像介质上,实现影像的显示,这样就能够实现在电子设备折叠状态时显示影像的投影显示,可以实现大屏显示效果,同时也能够实现信息的交互,丰富了电子设备的适用场景,提升电子设备的整体性能。The light outlet is located on the side of the projection bracket facing away from the flexible screen, that is, the light outlet faces the outside of the shell. An imaging medium can be provided on the opposite side of the shell. The imaging medium can be any structural member with reflective light characteristics, which can realize the display of the display image. The projection device can project the formed display image onto the imaging medium to realize the display of the image, so that the projection display of the image can be realized when the electronic device is in the folded state, and a large-screen display effect can be achieved. At the same time, information interaction can also be realized, which enriches the applicable scenarios of the electronic device and improves the overall performance of the electronic device.
在一种可能的实现方式中,外侧边面向本体的一端上设置有滑动件,外侧边通过滑动件与本体滑动配合,外侧边可沿第二方向滑动,第二方向与外侧边的长度延伸方向相垂直(也即与第一方向垂直)。设置在外侧边上的投影支架也就能够发生沿第二方向的滑动,也就是说投影支架相对本体及其上的柔性银幕能够滑动,投影支架在第二方向上滑动至不同的位置,出光口与柔性银幕之间的距离、出光口投射的显示影像在柔性银幕上的位置等均会发生变化,会在银幕上形成不同显示尺寸、精度等的显示影像,实现对显示影像的显示尺寸及精度的调节,提升显示效果。In a possible implementation, a sliding member is provided on one end of the outer edge facing the body, and the outer edge is slidably matched with the body through the sliding member, and the outer edge can slide along a second direction, and the second direction is perpendicular to the length extension direction of the outer edge (that is, perpendicular to the first direction). The projection bracket provided on the outer edge can also slide along the second direction, that is, the projection bracket can slide relative to the body and the flexible screen thereon, and the projection bracket slides to different positions in the second direction, and the distance between the light outlet and the flexible screen, the position of the display image projected by the light outlet on the flexible screen, etc. will all change, and display images of different display sizes, precisions, etc. will be formed on the screen, so that the display size and precision of the display image can be adjusted, and the display effect is improved.
此外,投影支架既可以转动设置在外侧边上,也可以通过外侧边相对本体滑动,使投影支架相对本体及其上的柔性银幕既能发生绕第一方向的转动,又能发生沿第二方向的移动,有利于提升显示效果调节的灵活性,进一步提升显示效果。In addition, the projection bracket can be rotatably set on the outer edge, and can also slide relative to the main body through the outer edge, so that the projection bracket can rotate around the first direction and move along the second direction relative to the main body and the flexible screen thereon, which is beneficial to improving the flexibility of adjusting the display effect and further improving the display effect.
在一种可能的实现方式中,投影装置设置在投影支架内,投影装置的投影面与出光口相对,影装置形成的显示影像从投影面射出,经过出光口后投射在柔性银幕上,实现影像的显示,结构设计难度较低,便于实现。In one possible implementation, the projection device is disposed in a projection bracket, and a projection surface of the projection device is opposite to a light outlet. A display image formed by the projection device is emitted from the projection surface, and is projected onto a flexible screen after passing through the light outlet, thereby realizing image display.

The volume of the reflection unit is relatively small, and compared with disposing the projection device in the projection bracket, it is beneficial to reduce the volume size of the projection bracket and improve the aesthetics of the electronic device.
在一种可能的实现方式中,投影装置的投影面面向两个壳体铺设有柔性银幕的一侧,反射单元包括至少一个反射元件,投影面射出的显示影像可以通过一个反射元件反射至出光口,以投射至柔性银幕上,结构设计简单且成本较低,便于实现。In one possible implementation, the projection surface of the projection device faces the side of the two shells on which the flexible screen is laid, and the reflection unit includes at least one reflection element.

The two shells may be connected to the two rotating mechanisms of the folding device 20 respectively, so that the two shells can rotate and cooperate through the folding device 20, so that the two shells can rotate relatively, that is, the first shell 11 and the second shell 12 can rotate relatively, so as to achieve folding and flattening of the electronic device 100.
其中,折叠装置20分别与第一壳体11、第二壳体12的连接实现方式可以是多种的,例如可以通过粘接、焊接、卡接、以及通过螺钉等紧固件实现连接等。There are many ways to connect the folding device 20 to the first shell 11 and the second shell 12, for example, bonding, welding, snap-fitting, and fasteners such as screws.
参见图1所示,第一壳体11和第二壳体12能够相对折叠至闭合状态,示例性的,第一壳体11和第二壳体12处于闭合状态,两者能够完全合拢至相互平行,此时电子设备100处于闭合状态,也称折叠状态,电子设备100折叠呈两层的形态。As shown in FIG. 1 , the first shell 11 and the second shell 12 can be folded relative to each other to a closed state. Exemplarily, the first shell 11 and the second shell 12 are in a closed state, and the two can be completely closed to be parallel to each other. At this time, the electronic device 100 is in a closed state, also called a folded state, and the electronic device 100 is folded into a two-layer form.
参见图2所示,第一壳体11和第二壳体12能够相对展开至打开状态,示例性的,第一壳体11和第二壳体12处于打开状态时,两者可以大致呈180°,此时电子设备100处于打开状态,也称展平状态。2 , the first shell 11 and the second shell 12 can be relatively unfolded to an open state. Exemplarily, when the first shell 11 and the second shell 12 are in the open state, the two can be approximately 180° apart. At this time, the electronic device 100 is in an open state, also called a flattened state.
电子设备100还可以具有中间状态,中间状态可以是打开状态与闭合状态之间的任意状态。也即电子设备100可以通过折叠装置20的运动,在打开状态(也即展平状态)与闭合状态(也即折叠状态)之间相互切换。The electronic device 100 may also have an intermediate state, which may be any state between the open state and the closed state. That is, the electronic device 100 may switch between the open state (i.e., the flattened state) and the closed state (i.e., the folded state) by the movement of the folding device 20.
常见的可折叠电子设备还包括柔性显示屏,柔性显示屏用于实现影像的显示,柔性显示屏还用于识别用户的操控信息等,以与用户实现人机交互,柔性显示屏多由具有显示功能、电信号处理功能以及触控功能等的特殊镀层层叠形成,通过内部发光的方式实现影像的显示。柔性显示屏通常铺设在折叠装置和壳体上,当电子设备处于折叠状态时,柔性显示屏位于两壳体之间,与折叠装置相对的部分柔性显示屏弯折位于折叠装置围成的容屏空间内。壳体相对打开时,柔性显示屏随之打开,当电子设备处于展平状态时,柔性显示屏平铺在壳体和折叠装置上,实现大屏显示。Common foldable electronic devices also include flexible display screens, which are used to display images. Flexible display screens are also used to identify user control information, etc., to achieve human-computer interaction with users. Flexible display screens are mostly formed by stacking special coatings with display functions, electrical signal processing functions, and touch functions, and display images through internal light emission. Flexible display screens are usually laid on the folding device and the housing. When the electronic device is in a folded state, the flexible display screen is located between the two housings, and the part of the flexible display screen opposite to the folding device is bent and located in the screen space surrounded by the folding device. When the housing is relatively opened, the flexible display screen opens accordingly. When the electronic device is in a flattened state, the flexible display screen is laid flat on the housing and the folding device to achieve a large-screen display.
而在不断的打开、闭合的过程中,由于柔性显示屏叠层复杂,弯折易产生分层现象。而且在撞击、碰撞等场景中,柔性显示屏也易受到损伤,而产生黑斑、碎亮点等显示不良的问题,显示可靠性较差。而且柔性显示屏自身的成本也较高,更换维护成本也高。此外,为保护柔性显示屏,当电子设备处于折叠状态时,柔性显示屏的弯折角度也会较大,导致电子设备的厚度较大,不利于电子设备的减薄化设计。In the process of continuous opening and closing, due to the complex stacking of flexible display screens, bending is prone to delamination. Moreover, in scenes such as impact and collision, flexible display screens are also easily damaged, resulting in poor display problems such as black spots and broken bright spots, and poor display reliability. Moreover, the cost of flexible display screens themselves is also high, and the cost of replacement and maintenance is also high. In addition, in order to protect the flexible display screen, when the electronic device is in a folded state, the bending angle of the flexible display screen will also be larger, resulting in a larger thickness of the electronic device, which is not conducive to the thinning design of the electronic device.
基于此,本申请实施例提供的一种具有柔性银幕的可折叠电子设备,使用柔性银幕和投影装置来实现柔性显示屏的功能,柔性银幕在弯折打开过程中、及跌落撞击等过程中不易损伤,具有较强的弯折耐久性,使用寿命长,具有更好的可靠性,柔性银幕的制造及维护成本较低,且有利于电子设备的减薄化。Based on this, an embodiment of the present application provides a foldable electronic device with a flexible screen, which uses a flexible screen and a projection device to realize the function of a flexible display screen. The flexible screen is not easily damaged during the bending and opening process, and during falling and impact. It has strong bending durability, long service life, and better reliability. The manufacturing and maintenance costs of the flexible screen are low, and it is conducive to the thinning of electronic devices.

以可折叠电子设备100包括一个折叠装置20和两个壳体为例,参见图2所示,可折叠电子设备100还包括柔性银幕30,柔性银幕30为自身不发光的结构件,具有反射光的特性,作为显示影像的显示载
体或成像介质,例如,柔性银幕可以是白色的幕布。柔性银幕30铺设在第一壳体11、第二壳体12和折叠装置20上,柔性银幕30可以设置在第一壳体11、第二壳体12以及折叠装置20的同一侧表面上。Taking the foldable electronic device 100 including a folding device 20 and two shells as an example, as shown in FIG. 2 , the foldable electronic device 100 also includes a flexible screen 30. The flexible screen 30 is a non-luminous structure having the property of reflecting light and serving as a display carrier for displaying images. The flexible screen 30 is arranged on the first shell 11, the second shell 12 and the folding device 20, and the flexible screen 30 can be arranged on the same side surface of the first shell 11, the second shell 12 and the folding device 20.
其中,柔性银幕30可以分别贴附固定在第一壳体11和第二壳体12上。具体的,柔性银幕30可以通过粘贴的方式贴附在第一壳体11和第二壳体12上,当然,在一些其他示例中,柔性银幕30也可以通过紧固件等其他方式贴附设置在第一壳体11和第二壳体12上。The flexible screen 30 can be attached and fixed to the first shell 11 and the second shell 12 respectively. Specifically, the flexible screen 30 can be attached to the first shell 11 and the second shell 12 by pasting. Of course, in some other examples, the flexible screen 30 can also be attached to the first shell 11 and the second shell 12 by other means such as fasteners.
当第一壳体11和第二壳体12转动并相对折叠,柔性银幕30贴附在第一壳体11和第二壳体12上并随之转动,而与折叠装置20相对的部分柔性银幕30发生弯折。当电子设备100处于折叠状态时,与折叠装置20相对的部分柔性银幕30容纳在折叠装置20围成的容屏空间21内(参见图11所示),电子设备100具有小的体积尺寸,便于携带。When the first shell 11 and the second shell 12 rotate and fold relative to each other, the flexible screen 30 is attached to the first shell 11 and the second shell 12 and rotates therewith, and the part of the flexible screen 30 opposite to the folding device 20 is bent. When the electronic device 100 is in the folded state, the part of the flexible screen 30 opposite to the folding device 20 is accommodated in the screen space 21 surrounded by the folding device 20 (see FIG. 11 ), and the electronic device 100 has a small size and is easy to carry.
当第一壳体11和第二壳体12相对展开,折叠装置20及柔性银幕30也随之展开。参见图2所示,当电子设备100处于展平状态时,柔性银幕30平铺在第一壳体11、第二壳体12和折叠装置20的同一侧表面上。When the first housing 11 and the second housing 12 are unfolded relative to each other, the folding device 20 and the flexible screen 30 are also unfolded. Referring to FIG. 2 , when the electronic device 100 is in a flattened state, the flexible screen 30 is laid flat on the same side surface of the first housing 11, the second housing 12 and the folding device 20.
其中,对于内折型的可折叠电子设备100,柔性银幕30设置在第一壳体11、第二壳体12以及折叠装置20的内侧表面。对于外折型的可折叠电子设备100,柔性银幕30设置在第一壳体11、第二壳体12以及折叠装置20的外侧表面。For the inward-folding foldable electronic device 100, the flexible screen 30 is arranged on the inner surface of the first shell 11, the second shell 12 and the folding device 20. For the outward-folding foldable electronic device 100, the flexible screen 30 is arranged on the outer surface of the first shell 11, the second shell 12 and the folding device 20.
需要说明的是,当电子设备100处于折叠状态,第一壳体11和第二壳体12相邻且相对的两个表面分别为第一壳体11和第二壳体12的内侧表面,折叠装置20与第一壳体11、第二壳体12的内侧表面同一侧的表面为折叠装置20的内侧表面。第一壳体11和第二壳体12相背的两个表面分别为第一壳体11和第二壳体12的外侧表面,折叠装置20与第一壳体11、第二壳体12的外侧表面同一侧的表面为折叠装置20的外侧表面。It should be noted that when the electronic device 100 is in a folded state, the two adjacent and opposite surfaces of the first shell 11 and the second shell 12 are the inner surfaces of the first shell 11 and the second shell 12, and the surface of the folding device 20 on the same side as the inner surfaces of the first shell 11 and the second shell 12 is the inner surface of the folding device 20. The two opposite surfaces of the first shell 11 and the second shell 12 are the outer surfaces of the first shell 11 and the second shell 12, and the surface of the folding device 20 on the same side as the outer surfaces of the first shell 11 and the second shell 12 is the outer surface of the folding device 20.
柔性银幕30自身不发光,为实现电子设备100的显示功能,继续参见图2所示,电子设备100还可以包括有投影装置40,投影装置40可以设置在其中一个壳体上,例如,可以设置在第一壳体11上,投影装置40能够形成显示影像。当电子设备100处于展平状态时,投影装置40能够将形成的显示影像投射至平铺的柔性银幕30上,实现影像的显示,也就实现了电子设备100展开后的大屏显示。The flexible screen 30 itself does not emit light. To realize the display function of the electronic device 100, as shown in FIG. 2 , the electronic device 100 may further include a projection device 40. The projection device 40 may be disposed on one of the housings, for example, on the first housing 11. The projection device 40 may form a display image. When the electronic device 100 is in a flattened state, the projection device 40 may project the formed display image onto the flat flexible screen 30 to realize the display of the image, thereby realizing a large-screen display after the electronic device 100 is unfolded.
而且柔性银幕30仅作为显示影像的显示载体或成像介质,自身不发光,也无显示功能、触控功能等的需求,其层叠结构较为简单,无需加入具有显示功能、电信号处理功能及触控功能等的镀层,具有较高的可靠性,在随着电子设备100的弯折及展开的过程中也不易受到损伤,能够减小或避免出现黑斑、碎亮点等显示不良的问题,在保证电子设备100显示功能的前提下,显著的提升了电子设备100的可靠性。而且柔性银幕30成本较低,有利于降低电子设备100的生产成本以及更换维护成本。Moreover, the flexible screen 30 is only used as a display carrier or imaging medium for displaying images. It does not emit light by itself, and does not require display functions or touch functions. Its laminated structure is relatively simple, and it does not need to add a coating with display functions, electrical signal processing functions, and touch functions. It has high reliability and is not easily damaged during the bending and unfolding of the electronic device 100. It can reduce or avoid the problems of poor display such as black spots and broken bright spots. Under the premise of ensuring the display function of the electronic device 100, the reliability of the electronic device 100 is significantly improved. In addition, the cost of the flexible screen 30 is relatively low, which is conducive to reducing the production cost and replacement and maintenance cost of the electronic device 100.
此外,当电子设备100处于折叠状态时,柔性银幕30的弯折角度要求也相对较小,在不对柔性银幕30造成损伤的条件下,柔性银幕30能够弯折至较小的弯折角度,也即实现更小角度的弯折,有利于减小电子设备100的厚度,利于实现电子设备100的减薄化设计。In addition, when the electronic device 100 is in a folded state, the bending angle requirement of the flexible screen 30 is relatively small. Without causing damage to the flexible screen 30, the flexible screen 30 can be bent to a smaller bending angle, that is, a smaller bending angle can be achieved, which is beneficial to reducing the thickness of the electronic device 100 and facilitating the thinning design of the electronic device 100.
其中,柔性银幕30可以是具有较好的柔软度以及较好的定向光线反射特性的结构件,例如,柔性银幕30的成型材料可以包括有软性树脂或玻塑材料,示例性的,柔性银幕30可以是白塑布、玻纤板、聚氯乙烯(Polyvinyl chloride,简称PVC))板等。Among them, the flexible screen 30 can be a structural component with good softness and good directional light reflection characteristics. For example, the molding material of the flexible screen 30 can include soft resin or glass plastic material. Exemplarily, the flexible screen 30 can be white plastic cloth, fiberglass board, polyvinyl chloride (PVC) board, etc.
柔性银幕30可以由一层材料层形成,或者,柔性银幕30也可以是层叠的结构,由多层材料层堆叠形成。The flexible screen 30 may be formed by a single material layer, or the flexible screen 30 may be a laminated structure formed by stacking multiple material layers.
其中,需要说明的是,信息的交互功能可以通过投影装置40实现,也即投影装置40既能实现影像的显示功能,也能够实现对用户操作信息的检测及获取等功能,实现人机交互。例如,在投影装置40内可以设置有操控功能传感器(参照图9所示),操控功能传感器能够检测并获取用户的操作信息。It should be noted that the information interaction function can be realized by the projection device 40, that is, the projection device 40 can realize the image display function, and can also realize the functions of detecting and obtaining user operation information, so as to realize human-computer interaction. For example, a control function sensor (as shown in FIG. 9 ) can be provided in the projection device 40, and the control function sensor can detect and obtain the user's operation information.
示例性的,操控功能传感器42可以为红外传感器,操控功能传感器42可以通过红外定位的方式检测并获取用户的操作信息,例如,通过发出的红外光来定位用户的操作在x、y、z三维方向上的位置或手势轨迹等,从而检测用户是否作出操作。并在用户作出操作时,获取形成操作的位置及轨迹等操作信息。操控功能传感器42可以与电子设备的主控板连接,操控功能传感器42可以将检测获取的操作信息传输至电子设备,从而使电子设备能够根据该操作信息作出反应,实现电子设备与用户的信息交互功能,进一步完善电子设备的性能。Exemplarily, the control function sensor 42 may be an infrared sensor, which may detect and obtain the user's operation information by infrared positioning, for example, by emitting infrared light to locate the position of the user's operation in the three-dimensional directions of x, y, and z or the trajectory of the gesture, thereby detecting whether the user has made an operation. When the user makes an operation, operation information such as the position and trajectory of the operation is obtained. The control function sensor 42 may be connected to the main control board of the electronic device, and the control function sensor 42 may transmit the detected operation information to the electronic device, so that the electronic device can react according to the operation information, realize the information interaction function between the electronic device and the user, and further improve the performance of the electronic device.
当然,在一些其他示例中,操控功能传感器42也可以是其他能够实现光定位识别功能的传感器,
例如操控功能传感器42还可以是激光传感器。Of course, in some other examples, the control function sensor 42 may also be other sensors capable of realizing the light positioning recognition function. For example, the control function sensor 42 may also be a laser sensor.
或者,信息的交互功能也可以通过其他结构实现,例如,可以通过下文中说明的,在壳体上与柔性银幕相对一侧设置的显示屏来实现,也即投影装置40只能实现投影显示功能,显示屏用来检测并获取用户的操作信息。Alternatively, the information interaction function can also be achieved through other structures, for example, it can be achieved through a display screen arranged on the side of the shell opposite to the flexible screen as described below, that is, the projection device 40 can only realize the projection display function, and the display screen is used to detect and obtain the user's operation information.
应当理解的是,在一些其他示例中,该可折叠电子设备也可以是笔记本电脑,笔记本电脑可以包括第一壳体和第二壳体,第一壳体和第二壳体能够相对折叠至闭合状态,使笔记本电脑处于闭合状态(也即折叠状态)。相应的,第一壳体和第二壳体从折叠状态起,相对展开至打开状态,笔记本电脑处于打开状态(也即展平状态),在第一壳体和第二壳体的至少一个上可以设置投影装置。在展平状态时,第一壳体上的至少部分柔性银幕可以用于实现图像等的显示,投影装置将形成的显示影像投射至该部分柔性银幕上,第二壳体上的至少部分柔性银幕可以作为虚拟键盘、虚拟鼠标盘等使用,投影装置也可以检测并获取用户的操作信息(例如,按键信息等)。It should be understood that in some other examples, the foldable electronic device may also be a laptop computer, and the laptop computer may include a first shell and a second shell, and the first shell and the second shell can be relatively folded to a closed state, so that the laptop computer is in a closed state (i.e., a folded state). Accordingly, the first shell and the second shell are relatively unfolded from the folded state to the open state, and the laptop computer is in an open state (i.e., a flattened state), and a projection device may be provided on at least one of the first shell and the second shell. In the flattened state, at least a portion of the flexible screen on the first shell can be used to display images, etc., and the projection device projects the formed display image onto the portion of the flexible screen, and at least a portion of the flexible screen on the second shell can be used as a virtual keyboard, a virtual mouse disk, etc., and the projection device can also detect and obtain user operation information (e.g., key information, etc.).

Referring to FIG. 11 , taking the projection bracket 50 arranged on the outer side 11a of the first shell 11 as an example, the extension direction of the outer side 11a is parallel to the x direction. An assembly groove 111 may be provided on the outer side 11a, and the projection bracket 50 may be arranged in the assembly groove 111. Specifically, one end of the projection bracket 50 may extend into the assembly groove 111, and one end of the projection bracket 50 may be fixedly connected to the outer side 11a, or one end of the projection bracket 50 may also be rotatably connected to the outer side 11a.
示例性的,投影支架50与外侧边11a可以通过轴孔配合的方式转动连接。例如,参见图12所示,在投影支架50的一端沿第一方向(与外侧边11a的长度延伸方向相平行的方向,例如平行于x方向)上相对的两端可以设置有凸起的转动件52,在装配槽111内沿第一方向上相对的两侧壁上可以设置有配位孔112。转动件52能够伸入配位孔112内,并与配位孔112转动配合,从而使投影支架50与外侧边11a转动配合,投影支架50能够发生绕第一方向的旋转,换言之,投影支架50能够相对本体11b及其上的柔性银幕30绕第一方向旋转。Exemplarily, the projection bracket 50 can be rotatably connected with the outer side 11a by means of a shaft hole matching. For example, referring to FIG. 12 , a protruding rotating member 52 can be provided at two opposite ends of one end of the projection bracket 50 along a first direction (a direction parallel to the length extension direction of the outer side 11a, for example, parallel to the x direction), and a matching hole 112 can be provided on two opposite side walls along the first direction in the assembly groove 111. The rotating member 52 can extend into the matching hole 112 and rotatably match with the matching hole 112, so that the projection bracket 50 can be rotatably matched with the outer side 11a, and the projection bracket 50 can rotate around the first direction. In other words, the projection bracket 50 can rotate around the first direction relative to the body 11b and the flexible screen 30 thereon.
其中,装配槽111开设在外侧边11a上,具体的,装配槽111可以从外侧边11a延伸至主体11b上,应当理解的是,为避让投影支架50,装配槽111至少位于外侧边11a边缘的部分为通槽,以便于实现投影支架50绕第一方向的旋转。例如,装配槽111位于外侧边11a上的部分为通槽,而延伸至主体11b的部分可以是通槽,或者,也可以是盲槽,具体的可以根据设计需求选择设定。The assembly groove 111 is provided on the outer side 11a.

For example, the portion of the assembly groove 111 located on the outer side 11a is a through groove, and the portion extending to the main body 11b can be a through groove, or can also be a blind groove, which can be specifically selected and set according to design requirements.
图13为本申请实施例提供的另一种可折叠电子设备处于折叠状态时的投影场景示意图。FIG13 is a schematic diagram of a projection scene when another foldable electronic device provided in an embodiment of the present application is in a folded state.
参见图13所示,当电子设备100处于折叠状态时,投影支架50经过转动后可以整体设置在装配槽111(图中未示出)内,从而通过装配槽111可以对投影支架50实现容纳隐藏,减小或避免投影支架50的设置对处于折叠态时电子设备100的体积尺寸及形状等的影响,保证电子设备100处于折叠状态时的小体积,以便于存储携带等,也有利于提升电子设备100的美观性。13 , when the electronic device 100 is in the folded state, the projection bracket 50 can be integrally disposed in the assembly groove 111 (not shown in the figure) after being rotated, so that the projection bracket 50 can be accommodated and hidden through the assembly groove 111, thereby reducing or avoiding the influence of the arrangement of the projection bracket 50 on the volume size and shape of the electronic device 100 in the folded state, ensuring the small volume of the electronic device 100 in the folded state, facilitating storage and carrying, etc., and also helping to improve the aesthetics of the electronic device 100.
其中,出光口51可以位于投影支架50背向柔性银幕30的一侧上,也即出光口51朝向第一壳体
11的外侧,在第一壳体11相对的一侧可以设置有成像介质90,成像介质90可以是任何具有反射光特性的结构件,能够实现显示影像的显示。投影装置40可以将形成的显示影像投射至成像介质90上,实现影像的显示,这样就能够实现在电子设备100折叠状态时显示影像的投影显示,可以实现大屏显示效果,同时也能够实现信息的交互,丰富了电子设备100的适用场景,提升电子设备100的整体性能。The light outlet 51 may be located on a side of the projection bracket 50 facing away from the flexible screen 30, that is, the light outlet 51 faces the first housing. An imaging medium 90 may be disposed on the outer side of the first housing 11, and on the side opposite to the first housing 11. The imaging medium 90 may be any structural member having a light reflecting property, and may realize the display of a display image. The projection device 40 may project the formed display image onto the imaging medium 90 to realize the display of the image, so that the projection display of the display image can be realized when the electronic device 100 is in a folded state, and a large-screen display effect can be realized. At the same time, information interaction can also be realized, which enriches the applicable scenarios of the electronic device 100 and improves the overall performance of the electronic device 100.
需要说明的是,电子设备100可以包括有成像介质90,例如,成像介质90为搭配电子设备100的幕布等结构件。或者,电子设备100中也可以不包括成像介质90,成像介质90可以是日常使用场景中的墙壁、桌面、投影幕布等。It should be noted that the electronic device 100 may include an imaging medium 90, for example, the imaging medium 90 is a structural member such as a screen that matches the electronic device 100.

Figure 15 is a schematic diagram of the flipping of the projection bracket in another foldable electronic device provided in an embodiment of the present application. Figure 16 is a schematic diagram of the partial cross-sectional structure of another foldable electronic device provided in an embodiment of the present application.
使第一壳体11、第二壳体12和第三壳体13转动以打开电子设备100,参见图14所示,当电子设备100处于展平状态时,投影支架50仍位于装配槽111内,可以转动投影支架50,使其绕第一方向旋转,结合图15所示,投影支架50可以转动至与柔性银幕30垂直,出光口51位于壳体铺设有柔性银幕30的一侧上方,出光口51位于投影支架50面向柔性银幕30的一侧,位于投影支架50内的投影装置40能够将显示影像投射至柔性银幕30上,以实现影像的显示以及信息交互等。The first shell 11, the second shell 12 and the third shell 13 are rotated to open the electronic device 100, as shown in Figure 14. When the electronic device 100 is in a flattened state, the projection bracket 50 is still located in the assembly groove 111. The projection bracket 50 can be rotated to rotate around the first direction. As shown in Figure 15, the projection bracket 50 can be rotated to be perpendicular to the flexible screen 30. The light outlet 51 is located above the side of the shell on which the flexible screen 30 is laid. The light outlet 51 is located on the side of the projection bracket 50 facing the flexible screen 30. The projection device 40 located in the projection bracket 50 can project the display image onto the flexible screen 30 to realize image display and information interaction.
其中,需要说明的是,投影支架50的旋转可以是用户手动操作,也就是说,参见图15所示,用户在打开电子设备100使其处于展平状态后,手动旋转投影支架50,将出光口51转动至面向柔性银幕30的一侧,以进行投影显示。It should be noted that the rotation of the projection bracket 50 can be manually operated by the user. That is to say, as shown in Figure 15, after the user opens the electronic device 100 to make it flat, the user manually rotates the projection bracket 50 and turns the light outlet 51 to the side facing the flexible screen 30 for projection display.
当然,在一些其他示例中,投影支架50的转动可以通过电子设备100驱动实现,例如,电子设备100内还可以设置有驱动结构(图中未示出),驱动结构可以与投影支架50连接,以驱动投影支架50旋转。其中,可以在电子设备100上设置有按钮,按钮可以与驱动结构配合,通过按钮可以使驱动结构运作,以驱动投影支架50旋转。或者,驱动结构也可以与折叠机构、壳体等配合,实现联动,在电子设备100打开或闭合的过程中自动实现投影支架50的旋转。Of course, in some other examples, the rotation of the projection bracket 50 can be driven by the electronic device 100. For example, a driving structure (not shown in the figure) can be provided in the electronic device 100, and the driving structure can be connected to the projection bracket 50 to drive the projection bracket 50 to rotate. Among them, a button can be provided on the electronic device 100, and the button can cooperate with the driving structure. The driving structure can be operated by the button to drive the projection bracket 50 to rotate. Alternatively, the driving structure can also cooperate with the folding mechanism, the housing, etc. to achieve linkage, and automatically realize the rotation of the projection bracket 50 during the opening or closing process of the electronic device 100.
此外,参见图16所示,投影支架50相对本体11b及其上的柔性银幕30发生绕第一方向的转动,投影支架50转动至不同位置时,会与柔性银幕30之间呈不同的倾斜角度,从出光口51投射的显示影像的投影角α(视场角)在柔性银幕30上的位置、投射的角度以及出光口51与柔性银幕30间的距离等均会发生变化,在柔性银幕30上会形成不同显示尺寸、不同显示精度等的显示影像。也就是说,可以通过调整投影支架50的旋转角度可以实现对显示影像的显示尺寸、精度等的调节,也就实现了对显示效果的调节,有利于提升显示效果。也可以针对不同的显示场景调整对应的显示效果,进一步提升电子设备100的显示功能。In addition, as shown in FIG. 16 , the projection bracket 50 rotates around the first direction relative to the body 11 b and the flexible screen 30 thereon. When the projection bracket 50 rotates to different positions, it will be at different inclination angles with the flexible screen 30. The projection angle α (field of view angle) of the display image projected from the light outlet 51 on the flexible screen 30, the projection angle, and the distance between the light outlet 51 and the flexible screen 30 will all change, and display images with different display sizes and different display accuracies will be formed on the flexible screen 30. In other words, the display size, accuracy, etc. of the display image can be adjusted by adjusting the rotation angle of the projection bracket 50, which also realizes the adjustment of the display effect, which is conducive to improving the display effect. The corresponding display effect can also be adjusted for different display scenes to further improve the display function of the electronic device 100.
其中,可以对投影支架50的旋转设置多个档位,每个档位对应投影支架50与柔性银幕30的一个倾斜角度,也就对应一种场景的显示尺寸及精度等。Among them, multiple gears can be set for the rotation of the projection bracket 50, and each gear corresponds to an inclination angle between the projection bracket 50 and the flexible screen 30, which corresponds to the display size and accuracy of a scene.

为实现对显示效果的调节,参见图17所示,在外侧边11a面向主体11b的一侧上可以设置有滑动件60,滑动件60与主体11b滑动配合,使外侧边11a通过滑动件60滑动设置在主体11b上,外侧边11a能够发生沿第二方向(垂直于上述第一方向,例如图中的y方向)的滑动。In order to adjust the display effect, as shown in Figure 17, a sliding member 60 can be provided on the side of the outer edge 11a facing the main body 11b. The sliding member 60 slides with the main body 11b, so that the outer edge 11a is slidably set on the main body 11b through the sliding member 60, and the outer edge 11a can slide along the second direction (perpendicular to the above-mentioned first direction, such as the y direction in the figure).
示例性的,主体11b和滑动件60可以采用滑轨配合的方式实现滑动连接,例如,在主体11b上可以开设有滑轨113,滑轨113的延伸方向可以与主体11b的长度方向(也即y方向)平行,外侧边11a一端与滑动件60连接,滑动件60的另一端可以伸入滑轨113内,并沿着滑轨113滑动,从而使滑动件60相对主体11b发生沿第二方向的滑动。Exemplarily, the main body 11b and the sliding member 60 can be slidably connected by means of a slide rail. For example, a slide rail 113 can be provided on the main body 11b, and the extension direction of the slide rail 113 can be parallel to the length direction of the main body 11b (that is, the y direction). One end of the outer edge 11a is connected to the sliding member 60, and the other end of the sliding member 60 can extend into the slide rail 113 and slide along the slide rail 113, so that the sliding member 60 slides along the second direction relative to the main body 11b.
当然,在一些其他示例中,滑动件60也可以采用其他方式实现与主体11b的滑动配合,例如,轨道与滚轮、皮带与滑轮等方式。Of course, in some other examples, the sliding member 60 may also adopt other methods to achieve sliding cooperation with the main body 11b, for example, a track and a roller, a belt and a pulley, etc.

The projection bracket 50 slides to different positions in the second direction, and the distance between the light outlet 51 and the flexible screen 30, the position of the display image projected by the light outlet 51 on the flexible screen 30, etc. will change, and display images with different display sizes and accuracies will be formed on the screen, thereby realizing the adjustment of the display size and accuracy of the display image and improving the display effect.

度等。Correspondingly, the sliding position of the projection bracket 50 can also be set to multiple gears, each gear corresponding to the display size and precision of a scene. Degrees, etc.

在对显示影像的显示效果实现调节时,可以使投影支架50既发生转动又发生滑动以达到调节的目的。或者,也可以仅通过投影支架50的转动实现调节。或者,也可以仅通过投影支架50的滑动来实现调节。When adjusting the display effect of the displayed image, the projection bracket 50 can be rotated and slid to achieve the purpose of adjustment. Alternatively, the adjustment can be achieved only by rotating the projection bracket 50. Alternatively, the adjustment can be achieved only by sliding the projection bracket 50.
当然,在一些其他示例中,投影支架50可以与外侧边11a转动配合,外侧边11a可以与主体11b固定,使投影支架50只能实现绕第一方向的旋转。或者,投影支架50可以固定设置在外侧边11a上,外侧边11a与主体11b滑动配合,使投影支架50只能实现沿第二方向的移动。Of course, in some other examples, the projection bracket 50 can be rotatably matched with the outer side 11a, and the outer side 11a can be fixed with the main body 11b, so that the projection bracket 50 can only rotate around the first direction. Alternatively, the projection bracket 50 can be fixedly set on the outer side 11a, and the outer side 11a and the main body 11b are slidably matched, so that the projection bracket 50 can only move along the second direction.
在本申请实施例中,参见图17所示,投影装置40可以设置在投影支架50内,投影装置40的投影面可以与出光口51相对,投影装置40形成的显示影像从投影面射出,经过出光口51后投射在柔性银幕30上。结构设计难度较低,便于实现。In the embodiment of the present application, as shown in FIG. 17 , the projection device 40 can be disposed in the projection bracket 50, the projection surface of the projection device 40 can be opposite to the light outlet 51, and the display image formed by the projection device 40 is emitted from the projection surface and is projected onto the flexible screen 30 after passing through the light outlet 51.

The display image emitted from the projection surface of the projection device 40 may be irradiated onto the reflection unit 70, and the display image is reflected to the light outlet 51 by the reflection unit 70. The display image is projected onto the flexible screen 30 after passing through the light outlet 51, thereby realizing the display of the image.

应当理解的是,改变反射单元70在投影支架50内的设置角度、反射角度等,也能够改变显示影像投射至柔性银幕30上的位置、投射的角度等,实现对显示影像的显示尺寸、精度等的调节,也能够便于提升显示效果。It should be understood that changing the setting angle, reflection angle, etc. of the reflection unit 70 in the projection bracket 50 can also change the position and projection angle of the displayed image projected onto the flexible screen 30, thereby adjusting the display size, accuracy, etc. of the displayed image, and can also facilitate improving the display effect.
其中,反射单元70可以仅包括一个反射元件,例如,反射单元70可以为一个反射镜。或者,反射单元70也可以包括多个反射元件,每个反射元件为一个反射镜,也即反射单元70由多个反射镜构成。The reflecting unit 70 may include only one reflecting element, for example, the reflecting unit 70 may be a reflecting mirror.

The reflection unit 70 can include multiple reflection elements, for example, two reflection elements, namely, reflection element 71 and reflection element 72. The display image emitted from the projection surface of the projection device 40 can first be irradiated to the reflection element 71, and then reflected to the reflection element 72 by the reflection element 71.
