Description

Support devices and electronic equipment

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on July 27, 2023, with application number 202322004399.8 and application name “Support device and electronic equipment”. The entire contents of the above application are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of electronic equipment, and in particular to a supporting device and electronic equipment. Background Art

[0003] With the development of modern technology, multifunctional electronic devices are becoming increasingly popular. Take foldable electronic devices (such as laptops, two-in-one products, etc.) as an example. Due to their advantages of small space occupation and easy use, they have been widely used in home and office environments.

[0004] Foldable electronic devices can be closed for storage when not in use, but must be manually unfolded by the user. The device's support mechanism must provide stable support for the display screen. Conventional support mechanisms often have complex structures, making unfolding and closing foldable electronic devices cumbersome and impacting the user experience.

[0005] Summary of the Invention

[0006] The present application provides a support device and an electronic device, which have a simple structure and can simplify user operations, thereby improving the user experience.

[0007] In a first aspect, the present application provides a support device comprising a base plate, a rotating plate, a support member, and a sliding member. The base plate has two ends extending in a first direction, respectively comprising a connecting end and a free end. The rotating plate is connected to the base plate at the connecting end, and the rotating plate is capable of rotating relative to the base plate around a first rotation axis to switch between an expanded state and a closed state. The first rotation axis extends in a second direction, which is perpendicular to the first direction. The support member has a first end and a second end, the first end of the support member is rotatably connected to the rotating plate and is capable of rotating relative to the rotating plate around a second rotation axis, which extends in the second direction. The sliding member is slidably disposed on the base plate, and is capable of sliding relative to the base plate between a first position and a second position along the first direction, with one end of the sliding member away from the free end being rotatably connected to the second end of the support member. When the rotating plate switches from the closed state to the expanded state, the sliding member slides to a first position away from the free end. When the rotating plate switches from the expanded state to the closed state, the sliding member slides to a second position close to the free end.

[0008] In some implementations of the present application, the support device can support an electronic device, which can be a two-in-one product. The electronic product includes a first component and a second component, wherein the first component is detachably connected to the rotating plate, and the second component is detachably connected to the base plate. For example, the first component can be a display screen or a device that supports a display screen, and the second component can be a keyboard or a device that supports a keyboard.

[0009] When the support device needs to be deployed, the user rotates the rotating plate away from the base plate. Driven by the rotating plate, the support member rotates relative to the sliding member while moving backward relative to the base plate, thereby driving the sliding member to slide backward. When the sliding member slides to the first position, the support device is in an deployed state. The rotating plate, the support member, and the sliding member form a triangular support structure. The center of gravity of the first member falls within the triangular support structure, thereby providing stable support for the first member. When the support device needs to be closed, the user rotates the rotating plate away from the base plate. Driven by the rotating plate, the support member rotates relative to the sliding member while moving forward relative to the base plate, thereby driving the sliding member to slide forward. During this process, the area of ​​the triangular region surrounded by the rotating plate, the support member, and the sliding member gradually decreases. When the sliding member slides to the second position, the support device is in a closed state. The first member fits with the second member. The support device can protect the electronic device.

[0010] By using the support assembly provided in this application, the user only needs to rotate the rotating plate to expand and close the electronic device. The operation is simple and convenient, thereby improving the user experience.

[0011] In some implementations of the present application, a hinge assembly is provided on the connecting end, and the base plate and the rotating plate are hingedly connected via the hinge assembly. The upper surface of the base plate is used to place the second component of the electronic device. The rotating plate has a front side and a back side. The front side is used to place the first component of the electronic device. The first end of the support member is rotatably connected to the back side. When the rotating plate is in a closed state, the front side faces the upper surface of the base plate. When the rotating plate is in an expanded state, the front side forms an angle with the upper surface of the base plate. By placing the first component on the front side of the rotating plate and rotatably connecting the first end of the support member to the back side of the rotating plate, the supporting force provided by the support member can be directly applied to the first component, thereby enhancing the reliability of the support. For example, the support member can be a support plate, and the support plate can increase the supporting strength.

[0012] In some implementations of the present application, the rotating shaft assembly includes a fixed seat and a rotating shaft that rotate with each other, that is, an axial hole is provided on the fixed seat, and the rotating shaft is installed in the axial hole and rotates with the axial hole; the fixed seat is connected to the base plate, and the rotating shaft is connected to the rotating plate. A damping structure is provided between the fixed seat and the rotating shaft. During the rotation of the rotating plate, the damping structure can provide a damping force for the rotating plate so that the rotating plate can stay stably at the set rotation angle, so that the user can rotate the rotating plate to the set position according to their own needs, thereby improving the user experience. In some implementations of the present application, a locking frame is provided on the end face of the rotating shaft, and the rotating plate is locked to the locking frame by screws to realize the connection between the rotating plate and the rotating shaft. The rotating shaft is provided with a threading hole extending along the axial direction of the rotating shaft, and the threading hole passes through the two end faces of the rotating shaft for threading. In some implementations of the present application, the threading hole can be an eccentric hole, that is, there is a certain distance between the axis of the threading hole and the axis of the rotating shaft, and the locking frame is arranged on the side with a thicker wall on the end face of the rotating shaft; by setting the threading hole as an eccentric hole, more space can be left for installing the locking frame, thereby increasing the thickness of the locking frame and enhancing the strength of the locking frame.

[0013] In some implementations of the present application, the bottom surface of the base plate is provided with an inwardly recessed notch, located near the connection end, and the sliding member is at least partially located within the notch. Providing a notch at one end of the bottom of the base plate near the connection end further reduces the weight of the device and allows the sliding member to be concealed and stored when the support device is in the closed state.

[0014] In some implementations of the present application, the sliding member includes a slide plate and a curved plate. The slide plate is slidably disposed within the notch, with the lower surface of the slide plate being higher than or flush with the lower surface of the base plate. The curved plate is curved toward a side away from the notch, with one end of the curved plate connected to an outer edge of the slide plate and the other end of the curved plate rotatably connected to the second end of the support member. The curvature of the curved plate can be designed based on the outer contour of the hinge assembly so that when the electronic device is in a closed state, the curved plate can cover the hinge assembly, thereby protecting the hinge assembly and improving the aesthetics of the device.

[0015] In other embodiments, a receiving groove can be provided on the side wall of the base plate connection end, with the opening of the receiving groove facing the rear side to accommodate the slide. However, since both the upper and lower walls of the receiving groove have a certain thickness, providing the receiving groove increases the thickness of the base plate. When the slide plate slides in the receiving groove, both the upper and lower surfaces of the slide plate will rub against the receiving groove, increasing the friction of the slide plate and causing it to slide unsmoothly. In addition, when the base plate is subjected to external pressure and the receiving groove is deformed, the upper and lower surfaces of the slide plate will contact the receiving groove, so the slide plate is prone to getting stuck during the sliding process. The embodiment of the present application provides a notch at one end of the bottom of the base plate near the connecting end, so that only the upper surface of the skateboard is in contact with the upper wall of the notch, and the lower surface of the skateboard is the appearance surface of the base plate and does not contact the base plate, thereby reducing the thickness and weight of the base plate, and reducing the friction when the skateboard slides, making the sliding smoother; in addition, when the base plate is subjected to external pressure and the notch is deformed, since there is no retaining wall under the skateboard to limit it, the skateboard can deform downward with the notch, so that the skateboard will not be stuck during the sliding process.

[0016] In some implementations of the present application, a sliding mechanism is provided between the slider and the notch. The sliding mechanism is used to restrict the slider's motion trajectory, allowing the slider to slide within the notch in a first direction. The sliding mechanism includes a guide rail and a slider. The guide rail is provided on the upper surface of the notch and extends in the first direction. The slider is provided on the upper surface of the slider and is slidably connected to the guide rail. Exemplarily, the guide rail is an ultra-thin guide rail. In some embodiments, the guide rail is formed from powder metallurgy, and the slider slides on the inner groove of the guide rail. Silent rollers are provided on the contact surface between the slider and the guide rail. The silent rollers can be made of a material with a low friction coefficient, such as Teflon, POM, or a round bar-shaped metal with a high surface finish. In addition to ensuring smoother sliding of the slider, the silent rollers can also reduce noise during sliding. In other embodiments, the guide rail can be stamped from stainless steel, with a hollow structure in the middle. The inner groove of the slider is snapped onto the guide rail. The slider can be made of a material with a low friction coefficient or a metal with a high surface finish.

[0017] In some implementations of the present application, a gap is provided between the upper surface of the slide and the upper surface of the notch, and a protrusion is provided on the upper surface of the slide, with the top of the protrusion contacting the upper surface of the notch. Providing the protrusion and utilizing the protrusion to contact the upper surface of the notch reduces the contact area compared to utilizing the entire upper surface of the slide to contact the upper surface of the notch, thereby reducing wear, noise, and sliding resistance.

[0018] In some implementations of the present application, the area where the protrusion rubs against the upper surface of the notch during sliding is the friction zone. When the rotating plate is in the extended state, the projection of the friction zone lies vertically within the projection of the sliding plate. By adopting this design, the area where the protrusion rubs against the upper surface of the notch is covered by the sliding plate, regardless of whether the support device is in the extended or closed state. This prevents the friction zone from being exposed and affecting the aesthetic appearance of the device.

[0019] In some implementations of the present application, the bottom of the skateboard is provided with a wear-resistant member made of a low-damping material. This prevents the bottom of the skateboard from being damaged by friction with the tabletop. For example, the wear-resistant member can be a foot pad made of Teflon, POM, or TPFE. The lower surface of the base plate can also be provided with a foot pad. The foot pads under the skateboard and the base plate can collectively raise the bottom of the support device as a whole, thereby preventing the base plate and the lower surface of the skateboard from contacting and rubbing against the tabletop.

[0020] In some implementations of the present application, a flexible connector is provided between the first end and the back surface of the support member, and between the second end of the support member and the bent plate. The flexible connector is made of a flexible material and is configured to bend and deform when subjected to force, thereby achieving a rotational connection between the first end and the back surface of the support member, and between the second end of the support member and the bent plate. For example, a veneer connection can be used between the first end and the back surface of the support member, and between the second end of the support member and the bent plate. The flexible connector can be a sheet made of PU. The bending deformation of the flexible sheet enables relative rotation between two adjacent components. This has a simple structure and can reduce the connection size, thereby forming a flat appearance.

[0021] In some implementations of the present application, there are two rotating shaft assemblies, and the two rotating shaft assemblies are spaced apart on both sides of the connecting end along the second direction. A storage groove is provided on the rotating plate in the area near the first rotation axis. The storage groove is located between the two rotating shaft assemblies. The storage groove is magnetic and is used to absorb accessories on the electronic device. For example, the accessory on the electronic device can be a stylus. The outside of the stylus can be provided with a pen cap. Both ends of the stylus and the pen cap are provided with magnets so that the user can firmly absorb the stylus and the pen cap in the storage groove. For example, a first magnetic component and a second magnetic component are provided on the outer wall of the storage groove. The first magnetic component can absorb the stylus alone, and the second magnetic component can absorb the pen cap alone, or it can absorb the pen cap with the stylus.

[0022] In a second aspect, the present application provides an electronic device comprising a first component, a second component, and a support device as in the first aspect, wherein the first component is disposed on a rotating plate and the second component is disposed on a bottom plate. In addition to being a laptop computer and a two-in-one product, the electronic device may also be other possible foldable electronic devices. The electronic device only needs to include two parts that can rotate relative to a rotating shaft assembly of any form. For example, the first component may be a display screen or a host computer having a display screen, and the second component may be a keyboard or a host computer having a keyboard. The first component and the second component may be opened and closed by a user driving the support device.

[0023] In some implementations of the present application, the electronic device further includes a stylus, and a storage slot is provided on the rotating plate in an area near the first rotation axis. The storage slot is magnetic, and the stylus can be detachably adsorbed in the storage slot for easy storage of the stylus. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0059] Embodiments of the present application provide a support device that can support an electronic device. For example, the electronic device can be a combination of a laptop computer and a tablet computer, known as a two-in-one product. However, the present application is not limited thereto and a tablet computer can also be used. According to this embodiment, the electronic product includes a first component 10 and a second component 20. For example, the first component 10 can be a display screen or a device that supports a display screen, and the second component 20 can be a keyboard or a device that supports a keyboard.

[0060] Referring to Figures 1 to 3, the support device provided in this embodiment includes a base plate 1, a rotating plate 2, a support member 3, and a sliding member 4. The base plate 1 extends along a first direction (e.g., the X direction shown in Figures 1(a) and 2 ) at two ends, respectively, comprising a connection end 11 and a free end 12. The rotating plate 2 is connected to the base plate 1 at the connection end 11 and is capable of rotating relative to the base plate 1 about a first rotation axis L1 to switch between an expanded state and a closed state. The first rotation axis L1 extends along a second direction (e.g., the Y direction shown in Figure 1(a) ), which is perpendicular to the first direction. The support member 3 has a first end and a second end. The first end of the support member 3 is rotatably connected to the rotating plate 2 and is capable of rotating relative to the rotating plate 2 about a second rotation axis L2, which extends along a second direction. The sliding member 4 is slidably disposed on the base plate 1 and is capable of sliding relative to the base plate 1 along the first direction between a first position and a second position. The end of the sliding member 4, distal from the free end 12, is rotatably connected to the second end of the support member 3. The first component 10 of the electronic device is detachably connected to the rotating plate 2, and the second component 20 of the electronic device is detachably connected to the base plate 1. When the rotating plate 2 switches from the closed state to the extended state, the slider 4 slides to a first position away from the free end 12, that is, slides backward (in the direction M1 shown in Figure 2); when the rotating plate 2 switches from the extended state to the closed state, the slider 4 slides to a second position closer to the free end 12, that is, slides forward (in the direction N1 shown in Figure 2).

[0061] When the support device needs to be unfolded, the user rotates the rotating plate 2 in the counterclockwise direction in Figure 2. Driven by the rotating plate 2, the support member 3 rotates relative to the sliding member 4 while moving backward relative to the base plate 1, thereby driving the sliding member 4 to slide backward; when the sliding member 4 slides to the first position, as shown in Figures 1(a) and 2, the support device is in an unfolded state, and the rotating plate 2, the support member 3 and the sliding member 4 form a triangular support structure. The center of gravity of the first component 10 falls into the triangular support structure, thereby providing stable support for the first component 10. When the support device needs to be closed, the user rotates the rotating plate 2 in the clockwise direction in Figure 2. Driven by the rotating plate 2, the support member 3 rotates relative to the sliding member 4 while moving forward (in the N1 direction as shown in Figure 2) relative to the base plate 1, thereby driving the sliding member 4 to slide forward. During this process, the area of ​​the triangular region surrounded by the rotating plate 2, the support member 3 and the sliding member 4 gradually decreases. When the sliding member 4 slides to the second position, as shown in Figure 1(b), the support device is in a closed state, the first component 10 is in contact with the second component 20, and the support device can protect the electronic equipment.

[0062] With the support assembly provided by the present application, the user only needs to rotate the rotating plate 2 to open and close the electronic device, which is simple and convenient to operate, thereby improving the user experience. In addition, the support assembly provided by the present application has a simple structure, is light in weight and thickness, and is easy for users to use and carry.

[0063] This application does not limit the specific structure of the rotational connection between the base plate 1 and the rotating plate 2. Any mechanism that can achieve the rotation of the rotating plate 2 relative to the base plate 1 is included in the scope of this application. In some implementations of this application, as shown in Figure 1(a), a rotating shaft assembly 5 is provided on the connecting end 11, and the base plate 1 and the rotating plate 2 are hingedly connected via the rotating shaft assembly 5. The upper surface of the base plate 1 is used to place the second component 20 of the electronic device. The rotating plate 2 has a front side 21 and a back side 22. As shown in Figure 2, the front side 21 usually faces the user in normal use, and the back side 22 is opposite to the front side 21 and faces away from the user in normal use. The front side 21 is used to place the first component 10 of the electronic device, and the first end of the support member 3 is rotatably connected to the back side 22. When the rotating plate 2 is in the closed state, the front side 21 faces the upper surface of the base plate 1. When the rotating plate 2 is in the extended state, the front side 21 forms an angle with the upper surface of the base plate 1 (such as the angle α shown in Figure 2). By placing the first component 10 on the front surface 21 of the rotating plate 2 and rotating the first end of the support member 3 to connect it to the rear surface 22 of the rotating plate 2, the supporting force provided by the support member 3 can be directly applied to the first component 10, thereby enhancing the reliability of the support. For example, the support member 3 can be a support plate that extends along the second direction to increase the support strength.

[0064] In some implementations of the present application, as shown in Figures 3(a) and 3(b), the rotating shaft assembly 5 includes a fixed base 51 and a rotating shaft 52 that rotate with each other. An axial hole is provided on the fixed base 51, and the rotating shaft 52 is installed in the axial hole and rotates with the axial hole. The fixed base 51 is connected to the base plate 1, and the rotating shaft 52 is connected to the rotating plate 2. A damping structure is provided between the fixed base 51 and the rotating shaft 52. During the rotation of the rotating plate 2, the damping structure can provide a damping force for the rotating plate 2 so that the rotating plate 2 can stably stay at the set rotation angle, so that the user can rotate the rotating plate 2 to the set position according to their own needs, thereby improving the user experience. In some implementations of the present application, a locking frame 54 is provided on the end face of the rotating shaft 52, and the rotating plate 2 is locked to the locking frame 54 by screws to achieve the connection between the rotating plate 2 and the rotating shaft 52. The rotating shaft 52 is provided with a threading hole 53 extending along the axis of the rotating shaft 52. The threading hole 53 passes through both end surfaces of the rotating shaft 52 for threading. In some implementations of the present application, the threading hole 53 may be an eccentric hole, that is, the axis of the threading hole 53 is spaced a certain distance from the axis of the rotating shaft 52, and the locking frame 54 is provided on the side of the rotating shaft 52 with a thicker wall. By setting the threading hole 53 as an eccentric hole, more space can be left for installing the locking frame 54, thereby increasing the thickness of the locking frame 54 and enhancing the strength of the locking frame 54.

[0065] Compared to the support devices in some other embodiments, the embodiments of the present application have better effects. For example, in some embodiments, as shown in Figure 10, the support device includes a mounting plate 101, a first placement plate 102, a first panel 103, a connecting plate 105, and a first support plate 104. The first placement plate 102 is slidably disposed on the upper surface of the mounting plate 101. One end of the first panel 103 is rotatably connected to one end of the first placement plate 102. The connecting plate 105 is in contact with and fixedly connected to the back of the first panel 103. The outer surface of the connecting plate 105 and the back of the first panel 103 are both provided with a PU sheet. One end of the first support plate 104 is rotatably connected to one end of the mounting plate 101, and the other end of the first support plate 104 is rotatably connected to the connecting plate 105. The first panel 103 is used to place the first component 10, and the first placement plate 102 is used to place the second component 20. When the support device is placed on a desktop, the lower surface of the mounting plate 101 contacts the desktop. When the support device needs to be deployed, the user flips the first panel 103 in a direction away from the first placement plate 102 (in the counterclockwise direction in Figure 10). The first panel 103 rotates while driving the first placement plate 102 to slide forward (in the N3 direction as shown in Figure 10). When the support device is in the deployed state, the stopper can limit the first panel 103 or the first placement plate 102, so that the first panel 103 stays at a set angle. At this time, the first placement plate 102, the first panel 103 and the first support plate 104 form a triangular support structure. The center of gravity of the first component 10 falls within the triangular support structure, thereby providing stable support for the first component 10. When the support device needs to be closed, the user flips the first panel 103 in a direction close to the first placement plate 102 (in the clockwise direction in Figure 10). The first panel 103 rotates while driving the first placement plate 102 to slide backward (in the M3 direction as shown in Figure 10) until the first component 10 and the second component 20 are in contact.

[0066] While the embodiment shown in Figure 10 can support the first component 10, the sliding surface between the first placement plate 102 and the mounting plate 101 is large, making it susceptible to scratching. Furthermore, the support structure is relatively complex. When the support device is closed, it comprises, from top to bottom, a PU sheet, a connecting plate 105, a PU sheet, a first panel 103, the first placement plate 102, and the mounting plate 101. This complex structure results in considerable weight and thickness.

[0067] In comparison, in the support device provided by the present application, the sliding surface between the sliding member 4 and the base plate 1 is smaller, which can reduce scratches. In addition, the rotating plate 2 adopts a PU-wrapped frame design, eliminating the connecting plate 105 and simplifying the structure. Moreover, the base plate 1 does not have the staggered structure of relative sliding between the mounting plate 101 and the first placement plate 102 shown in Figure 10. Therefore, the support device provided by the present application includes, from top to bottom, the following: support member 3, rotating plate 2 and base plate 1. Its structure is simple, and its weight and thickness are both relatively low.

[0068] In the embodiment shown in FIG10 , since the user may hold the front end of the first placement plate 102 with one hand when the support device is unfolded, it is easy to cause the first placement plate 102 to deform. Therefore, it is necessary to set a reinforcing carbon plate or other structural parts in the first placement plate 102 to enhance the strength of the first placement plate 102. In some embodiments of the present application, the base plate 1 includes an upper base plate 14 and a lower base plate 15. The lower surface of the upper base plate 14 is in contact with the upper surface of the lower base plate 15, and the two are fixedly connected. The present application increases the strength of the base plate 1 by setting the base plate 1 as a double-layer structure, thereby preventing accidental touches of the touch panel caused by deformation of the base plate 1. At the same time, since there is no staggered structure between the upper base plate 14 and the lower base plate 15 that can slide relative to each other as in the embodiment of FIG10 , there is no need to set a reinforcing carbon plate or other structural parts in the upper base plate 14 for enhancing strength, thereby reducing weight, thickness and manufacturing cost.

[0069] In addition, in the embodiment shown in Figure 10, the first panel 103 cannot be rotatably connected to the first placement plate 102 via the rotating shaft assembly 5 with a damping structure. This is because if a rotating shaft assembly 5 with a damping structure is set between the first panel 103 and the first placement plate 102, the user must press the first placement plate 102 with one hand and flip the first panel 103 with the other hand to unfold the support device. When the support device in Figure 10 is unfolded, the first placement plate 102 will slide forward, so the user cannot apply pressure to the first placement plate 102, which results in the first panel 103 being unable to be rotatably connected to the first placement plate 102 via the rotating shaft assembly 5 with a damping structure. Therefore, the first panel 103 needs to stay in a preset position under the limiting action of the limiting member, and the rotation angle of the first panel 103 cannot be infinitely adjusted. In the support device provided in the present application, the base plate 1 does not need to slide, and the user can press it to unfold the support device. Therefore, the rotating plate 2 can be rotatably connected to the base plate 1 via the rotating shaft assembly 5 with a damping structure, and the rotation angle of the rotating plate 2 in the present application can be infinitely adjusted. In addition, in the embodiment shown in Figure 10, the front end of the first placement plate 102 may be misaligned with the front end of the mounting plate 101 during the sliding process, causing the user's hands to be pinched. In the support device provided by this application, the sliding member 4 is located at the bottom rear side of the base plate 1, away from the user's hands, so the user's hands will not be pinched.

[0070] For example, in some other embodiments, as shown in FIG11 , the support device includes a second placement plate 201, a second support plate 202, a second panel 203, a first hinge 204, and a second hinge 205. The second panel 203 is used to place the first component 10, and the second placement plate 201 is used to place the second component 20. One end of the second support plate 202 is hinged to the end of the second placement plate 201 via the first hinge 204, and the other end of the second support plate 202 is hinged to the end of the second panel 203 via the second hinge 205. When the support device is deployed, the first hinge 204 acts as a stop for the second support plate 202, and the second hinge 205 acts as a stop for the second panel 203. The second support plate 202, the second placement plate 201, and the first hinge 204 form two sides and a vertex of a support triangle, so that the center of gravity of the first component 10 falls within the support triangle, thereby providing support for the first component 10.

[0071] Although the embodiment shown in FIG11 can support the first component 10, the entire weight of the first component 10 falls on the second support plate 202. Therefore, the second support plate 202 and the first hinge shaft 204 need to be made very thick to increase the strength of the second support plate 202 and the first hinge shaft 204. This results in a heavy weight and thickness of the support device. In addition, in the embodiment shown in FIG11, when the electronic device is unfolded, the first component 10 is suspended above the second placement plate 201. Therefore, the area of ​​the second placement plate 201 near the first hinge shaft 204 needs to be kept clear of air. This means that only second components 20 with a smaller width can be placed on the second placement plate 201, thereby affecting the user experience.

[0072] In comparison, in the support device provided by the present application, since the support member 3 is connected to the sliding member 4, and the sliding member 4 is slidably connected to the base plate 1, the support member 3 will transfer the weight of the first component 10 to the sliding member 4 and the base plate 1, and the support member 3 will not bear the entire gravity from the first component 10. The support member 3 does not need to be processed to be very thick and heavy. Therefore, the thickness and weight of the support device provided by the present application are relatively small, making it easy for users to carry. In addition, when the support device provided by the present application is unfolded, the first component 10 is not suspended above the base plate 1, so the base plate 1 does not need to be kept clear of air, and the second component 20 with a larger width can be placed on the base plate 1, thereby improving the user experience.

[0073] 2 and 6( b ), in some implementations of the present application, the lower surface of the base plate 1 is provided with an inwardly recessed notch 13, which is located near the connecting end 11, and the slider 4 is at least partially located within the notch 13. Providing the notch 13 at one end of the bottom of the base plate 1 near the connecting end 11 further reduces the weight of the device and allows the slider 4 to be concealed and stored when the support device is in the closed state.

[0074] 4 and 6(a), in some implementations of the present application, the sliding member 4 includes a slide plate 41 and a bent plate 42. The slide plate 41 is slidably disposed in the notch 13. The lower surface of the slide plate 41 is higher than the lower surface of the base plate 1, or the lower surface of the slide plate 41 is flush with the lower surface of the base plate 1. The bent plate 42 is bent toward the side away from the notch 13, one end of the bent plate 42 is connected to the outer edge of the slide plate 41 (i.e., the edge of the slide plate 41 away from the free end 12), and the other end of the bent plate 42 is rotatably connected to the second end of the support member 3. The curvature of the bent plate 42 can be designed according to the outer contour of the hinge assembly 5, so that when the electronic device is in a closed state, the bent plate 42 can cover the hinge assembly 5, protect the hinge assembly 5, and improve the aesthetic appearance of the device.

[0075] Referring to FIG9 , in other embodiments, a receiving groove 301 is provided on the side wall of the connecting end 11 of the base plate 1, with the opening of the receiving groove 301 facing the rear side (such as the M2 direction as shown in FIG9 ) to accommodate the slide plate 41. However, since both the upper and lower walls of the receiving groove 301 have a certain thickness, the provision of the receiving groove 301 increases the thickness of the base plate 1. Moreover, when the slide plate 41 slides in the receiving groove 301, both the upper and lower surfaces of the slide plate 41 rub against the receiving groove 301, increasing the friction force of the slide plate 41 and causing the slide plate 41 to slide unsmoothly. In addition, when the base plate 1 is subjected to external pressure and the receiving groove 301 is deformed, since both the upper and lower surfaces of the slide plate 41 are in contact with the receiving groove 301, the slide plate 41 is easily stuck during the sliding process.

[0076] In comparison, the embodiment of the present application provides a notch 13 at one end of the bottom of the base plate 1 near the connection end 11, so that only the upper surface of the slide plate 41 contacts the upper wall of the notch 13. The lower surface of the slide plate 41 serves as the exterior surface of the base plate 1 and does not contact the base plate 1, thereby reducing the thickness and weight of the base plate 1 and also reducing friction when the slide plate 41 slides, making the sliding motion smoother. In addition, when the base plate 1 is subjected to external pressure and the notch 13 is deformed, since there is no retaining wall below the slide plate 41 to restrict it, the slide plate 41 can deform downward along with the notch 13, thereby preventing the slide plate 41 from getting stuck during the sliding process.

[0077] 4 , in some implementations of the present application, a sliding mechanism 6 is provided between the sliding member 4 and the notch 13 , and the sliding mechanism 6 is used to limit the movement trajectory of the sliding member 4 so that the sliding member 4 slides in the notch 13 along a first direction.

[0078] Referring to Figures 5(a) and 5(b), in some implementations of the present application, the sliding mechanism 6 includes a guide rail 61 and a slider 62. The guide rail 61 is provided on the upper surface of the notch 13 and extends along the first direction in which the sliding member 4 slides in the notch 13. The slider 62 is provided on the upper surface of the slide plate 41, and the slider 62 is slidably connected to the guide rail 61. Exemplarily, the guide rail 61 is an ultra-thin guide rail. In some embodiments, the guide rail 61 is made of powder metallurgy, and the slider 62 slides on the inner groove of the guide rail 61. The contact surface between the slider 62 and the guide rail 61 is provided with a silent roller 63. The material of the silent roller 63 can be a material with a low friction coefficient, such as Teflon, POM or a round rod-shaped metal with a high surface finish. In addition to making the slider 62 slide more smoothly, the silent roller 63 can also reduce noise during the sliding process.

[0079] In other embodiments, the guide rail 61 can also be made of stainless steel stamping, the middle part of the guide rail 61 is a hollow structure, the inner groove of the slider 62 is clamped on the guide rail 61, and the material of the slider 62 can be a material with a low friction coefficient or a metal with a high surface finish.

[0080] Referring to FIG. 6( a ), in some implementations of the present application, a gap is provided between the upper surface of the slide plate 41 and the upper surface of the notch 13. A protrusion 411 is provided on the upper surface of the slide plate 41, and the top of the protrusion 411 contacts the upper surface of the notch 13. Protrusions 411 are provided and contact is made with the upper surface of the notch 13. Compared to contacting the entire upper surface of the slide plate 41 with the upper surface of the notch 13, the contact area can be reduced, thereby reducing wear, noise, and sliding resistance.

[0081] 7(a) and 7(b), in some implementations of the present application, the area where the protrusion 411 generates friction with the upper surface of the notch 13 during sliding is the friction area S. When the rotating plate 2 is in the extended state, the vertical projection of the friction area S is located within the projection range of the slide plate 41. By adopting the above design, whether the support device is in the extended state (as shown in FIG. 7(a)) or the closed state (as shown in FIG. 7(b)), the friction area S can be covered by the slide plate 41, thereby preventing the friction area S from being exposed and affecting the aesthetic appearance of the device.

[0082] In some implementations of the present application, the bottom of the slide 41 is provided with a wear-resistant member made of a low-damping material. This prevents the bottom of the slide 41 from being damaged by friction with the tabletop. For example, the wear-resistant member can be a foot pad made of Teflon, POM, or TPFE. The lower surface of the base plate 1 can also be provided with a foot pad. The foot pads under the slide 41 and the foot pads under the base plate 1 can jointly raise the bottom of the support device as a whole, thereby preventing contact and friction between the base plate 1 and the lower surface of the slide 41 and the tabletop.

[0083] Referring to FIG. 4 , in some implementations of the present application, a flexible connector 71 is provided between the first end of the support member 3 and the rear surface 22, and between the second end of the support member 3 and the curved plate 42. The flexible connector 71 is made of a flexible material and is configured to bend and deform when subjected to force, thereby achieving a rotational connection between the first end of the support member 3 and the rear surface 22, and between the second end of the support member 3 and the curved plate 42. For example, a veneer connection can be used between the first end of the support member 3 and the rear surface 22, and between the second end of the support member 3 and the curved plate 42. Specifically, a layer of flexible material 7 is attached to the rear surface of the rotating plate 2, the outer surface of the support member 3, and the outer surface of the sliding member 4. The flexible material 7 between the first end of the support member 3 and the rear surface 22, and between the second end of the support member 3 and the curved plate 42 constitutes the flexible connector 71. For example, the flexible material 7 can be a sheet made of polyurethane (PU), which has a simple structure and can reduce the connection size, thereby creating a smooth appearance.

[0084] Referring to Figures 8(a), 8(b), and 4, in some implementations of the present application, there are two hinge assemblies 5, spaced apart along the second direction on either side of the connecting end 11. A receiving slot 23 is provided on the rotating plate 2 near the hinge assemblies 5. The receiving slot 23 is located between the two hinge assemblies 5 and is magnetic. The receiving slot 23 is used to retain accessories on the electronic device. For example, the accessory on the electronic device may be a stylus 30, which may be provided with a pen cap 40 on its exterior. Both ends of the stylus 30 and the pen cap 40 may be provided with magnets, allowing a user to securely retain the stylus 30 and the pen cap 40 within the receiving slot 23. For example, a first magnetic member 231 and a second magnetic member 232 are provided on the outer wall of the receiving slot 23. The first magnetic member 231 can retain the stylus 30 alone, and the second magnetic member 232 can retain the pen cap 40 alone, or can retain the pen cap 40 with the stylus 30 attached.

[0085] With reference to Figures 1(a), 1(b) and 2, the present application also provides an electronic device, which includes a first component 10, a second component 20 and any of the aforementioned support devices, wherein the first component 10 is provided on the rotating plate 2, and the second component 20 is provided on the bottom plate 1. In addition to being a laptop computer and a two-in-one product, the electronic device can also be other possible foldable electronic devices. The electronic device only needs to include two parts that can rotate relative to a rotating shaft assembly 5 of any form. For example, the first component 10 can be a display screen or a host with a display screen, and the second component 20 can be a keyboard or a host with a keyboard. The first component 10 and the second component 20 can be opened and closed by the user driving the support device. The aforementioned support device is used in the electronic device provided in the present application. Since the structure of the support device is simple, the electronic device can be made lighter and thinner.

[0086] In some implementations of the present application, the electronic device further includes a stylus 30 , and a storage slot 23 is provided on the rotating plate 2 in an area near the first rotation axis L1 . The storage slot 23 is magnetic, and the stylus 30 can be detachably adsorbed in the storage slot 23 to facilitate storage of the stylus 30 .
