Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an electronic device. Background Technology

[0002] In related technologies, foldable electronic devices typically have two forms: folded and unfolded.

[0003] Specifically, the first frame and the second frame are connected by a hinge to realize the folding and unfolding of the electronic device. This makes the first frame and the second frame without a frame at the position where the hinge is set. When the electronic device is folded, the hinge forms a side of the electronic device, and the side where the hinge is located has a low support capacity for the first frame and the second frame.

[0004] If an electronic device falls while folded, and the sharp corners of the first and second frames corresponding to the hinge are impacted, the hinge will not be able to provide adequate support for the first and second frames, causing the frames to deform. Summary of the Invention

[0005] This application aims to provide an electronic device that at least solves one of the technical problems of easy deformation of the frame of foldable electronic devices at the hinge position.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows:

[0007] This application provides an electronic device, including:

[0008] First screen assembly, frame assembly, and hinge assembly;

[0009] The frame assembly includes a first frame and a second frame, which are rotatably connected by a hinge assembly to allow the electronic device to switch between an unfolded state and a folded state.

[0010] The hinge assembly includes a base, a swing arm mechanism, and a screen support plate. The swing arm mechanism is rotatably connected to the base, and the screen support plate is disposed on one side of the swing arm mechanism and rotates with the swing arm mechanism. The screen support plate is used to support the first screen assembly.

[0011] In this configuration, along the first direction, support members are provided on both sides of the screen support plate. The support members are fixedly connected to the screen support plate. The support members are provided with sliding grooves. The swing arm mechanism is provided with pins. The pins are at least partially located in the sliding grooves. During the rotation of the swing arm mechanism relative to the base, the pins slide along the sliding grooves. The support members and the screen support plate rotate synchronously. The first direction is the rotation axis of the swing arm mechanism.

[0012] In embodiments of this application, the electronic device includes a first screen assembly, a frame assembly, and a hinge assembly. The frame assembly includes a first frame and a second frame, which are rotatably connected via the hinge assembly to allow the electronic device to switch between an unfolded state and a folded state.

[0013] The hinge assembly includes a base, a swing arm mechanism, and a screen support plate. The swing arm mechanism is rotatably connected to the base to realize the opening and closing of the hinge. The screen support plate is disposed on one side of the swing arm mechanism and rotates with the swing arm mechanism. The screen support plate is used to support the first screen assembly, so that when the electronic device is in the unfolded state, the screen support plate can support the first screen assembly from below.

[0014] The swing arm mechanism has a rotation axis in the first direction. Along the first direction, support members are provided on both sides of the screen support plate. The support members are fixedly connected to the screen support plate. The support members are provided with a sliding groove. The swing arm mechanism is provided with a pin. The pin is at least partially located in the sliding groove. During the rotation of the swing arm mechanism relative to the base, the pin slides along the sliding groove. Since the rotation centers of the screen support plate and the swing arm mechanism are different, by providing the pin and the sliding groove, the support member can rotate synchronously with the screen support plate when it is connected to the screen support plate and the hinge assembly.

[0015] The electronic device provided in this application embodiment adds a support member to the hinge assembly. The support member can extend from both ends of the screen support plate. Furthermore, the support member can support the screen support plate while providing support for the frame assembly, thereby reducing the possibility that the frame assembly is easily deformed at the position corresponding to the hinge assembly when the electronic device is dropped, and improving the reliability of the electronic device.

[0051] The following is combined with Figures 1 to 27 An electronic device 1 according to an embodiment of this application is described.

[0052] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10, Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown in the figure, this application provides an electronic device 1, including: a first screen assembly 11, a frame assembly 12, and a hinge assembly 13; the frame assembly 12 includes a first frame 121 and a second frame 124, the first frame 121 and the second frame 124 are rotatably connected by the hinge assembly 13, so that the electronic device 1 can switch between an unfolded state and a folded state; the hinge assembly 13 includes a base 131, a swing arm mechanism 132, and a screen support plate 137, the swing arm mechanism 132 is rotatably connected to the base 131, and the screen support plate 137 is disposed on one side of the swing arm mechanism 132 and moves with the swing arm mechanism. The screen support plate 137 is used to support the first screen assembly 11. Support members 139 are provided on both sides of the screen support plate 137 along the first direction Y. The support members 139 are fixedly connected to the screen support plate 137. The support members 139 are provided with a sliding groove 140. The swing arm mechanism 132 is provided with a pin 133, which is at least partially located within the sliding groove 140. During the rotation of the swing arm mechanism 132 relative to the base 131, the pin 133 slides along the sliding groove 140, and the support members 139 and the screen support plate 137 rotate synchronously. The first direction Y is the rotation axis of the swing arm mechanism 132. Figure 1 The X, Y, and Z directions are perpendicular to each other, with the Z direction being perpendicular to the first screen component 11 and the X direction being perpendicular to both the Z and Y directions.

[0053] In the embodiments of this application, the electronic device 1 includes a first screen assembly 11, a frame assembly 12, and a hinge assembly 13. The frame assembly includes a first frame 121 and a second frame 124. The first frame 121 and the second frame 124 are rotatably connected by the hinge assembly 13 so that the electronic device 1 can switch between an unfolded state and a folded state.

[0054] The hinge assembly 13 is connected to the first frame 121 and the second frame 124 on both sides, and the first screen assembly 11 is located on one side of the first frame 121 and the second frame 124. Thus, the opening and closing of the hinge assembly 13 realizes the unfolding and folding of the first frame 121 and the second frame 124. When the electronic device 1 is in a folded state, the first screen assembly 11 can be located on the outside or inside of the frame assembly 12.

[0055] The hinge assembly 13 includes a base 131, a swing arm mechanism 132, and a screen support plate 137. The swing arm mechanism 132 is rotatably connected to the base 131 to realize the opening and closing of the hinge. The screen support plate 137 is disposed on one side of the swing arm mechanism 132 and rotates with the swing arm mechanism. The screen support plate 137 is used to support the first screen assembly 11, so that when the electronic device 1 is in the unfolded state, the screen support plate 137 can support the first screen assembly 11 from below.

[0056] There can be two swing arm mechanisms 132 and screen support plates 137. One swing arm mechanism 132 is connected to the first frame 121, and the other swing arm mechanism is connected to the second frame 124, so that the first frame 121 and the second frame 124 move synchronously with the hinge assembly 13. One screen support plate 137 supports the first screen assembly 11 in the first frame 121, and the other screen support plate 137 supports the first screen assembly 11 in the second frame 124.

[0057] The swing arm mechanism 132 rotates along the first direction Y. Support members 139 are provided on both sides of the screen support plate 137 along the first direction Y. The support members 139 are fixedly connected to the screen support plate 137. The support members 139 are provided with a sliding groove 140. The swing arm mechanism 132 is provided with a pin 133. The pin 133 is at least partially located in the sliding groove 140. During the rotation of the swing arm mechanism 132 relative to the base 131, the pin 133 slides along the sliding groove 140. Since the rotation centers of the screen support plate 137 and the swing arm mechanism 132 are different, by providing the pin 133 and the sliding groove 140, the support member 139 can rotate synchronously with the screen support plate 137 when the support member 139 is connected to the screen support plate 137 and the hinge assembly.

[0058] Since the support member 139 is located at both ends of the screen support plate, in order for the first screen assembly 11 to be well supported, the support member 139 needs to be connected to the screen support plate 137.

[0059] However, the screen support plate 137 has a large range of motion in the first direction Y of the hinge assembly 13. Since the main function of the screen support plate 137 is to shape the teardrop shape of the first screen assembly 11 when the electronic device 1 is folded, and to support the first screen assembly 11 when the electronic device 1 is unfolded, its function is mainly reflected in the second direction of the hinge assembly 13. The degree of freedom in the first direction Y is mainly due to the large assembly tolerances required for the screen support plate 137 to coordinate with the assembly of multiple components, resulting in a large degree of freedom in the first direction Y of the hinge assembly 13, with gaps reaching 0.5mm.

[0060] Furthermore, in order to improve the reliability of the support member 139 in supporting the frame assembly 12, it is also necessary to cooperate with the pin 133 and the slide 140 to make the support member 139 and the swing arm mechanism 132 cooperate. The swing arm mechanism 132 has a compact structure and high strength. Therefore, when the frame assembly 12 is subjected to force at the sharp corner corresponding to the hinge assembly 13, the support member 139 can provide support for the frame assembly 12 through the screen support plate and the swing arm mechanism 132, thereby improving the support effect of the support member 139 on the frame assembly 12.

[0061] The electronic device 1 provided in this application embodiment adds a support member 139 to the hinge assembly 13. The support member 139 can extend from both ends of the screen support plate 137. Furthermore, the support member 139 can provide support for the frame assembly 12 while supporting the screen support plate 137, thereby reducing the possibility that the frame assembly 12 is easily deformed at the position corresponding to the hinge assembly 13 when the electronic device 1 is dropped, and improving the reliability of the electronic device 1.

[0062] The electronic device 1 provided in this application embodiment mainly utilizes the small movement space of the swing arm mechanism 132 in the first direction Y of the hinge assembly 13. A support member 139 is added to the swing arm mechanism 132. The support member 139 and the swing arm mechanism 132 are arranged along the first direction Y. At the same time, since the material strength of the swing arm mechanism 132 and the support member 139 is usually greater than that of the frame assembly 12, when the electronic device 1 falls and the edge of the frame assembly 12 is impacted, the small movement space of the swing arm mechanism 132 in the first direction Y allows the swing arm mechanism 132 and the support member 139 to support the frame assembly 12, reducing the possibility of the frame assembly 12 arching and deforming towards the inside or outside of the electronic device 1, thereby reducing the possibility of cracking of the first screen assembly 11 caused by the tensile stress of the deformation of the frame assembly 12.

[0063] Optionally, such as Figure 4 As shown, the gap between the swing arm mechanism 132 and the support member 139 is less than or equal to 0.1 mm and greater than 0 mm. Theoretically, as long as there is a gap between the swing arm mechanism 132 and the support member 139, the swing arm mechanism 132 can rotate smoothly. However, due to machining errors and other reasons, the gap between the swing arm mechanism 132 and the support member 139 can be less than or equal to 0.1 mm and greater than 0.02 mm.

[0064] The electronic device 1 provided in this application embodiment adds support members 139 on both sides of the screen support plate 137 of the hinge assembly 13 and makes the support members 139 and the swing arm mechanism 132 movably connected. Since the support members 139 and the swing arm mechanism 132 fit tightly, only a gap of 0.05mm needs to be maintained in the first direction Y of the hinge assembly 13, so that the support members 139 have a small degree of freedom in the first direction Y of the hinge assembly 13, and the fitting gap with the frame assembly 12 will also be smaller.

[0065] When the electronic device 1 is in a folded state, if the end of the hinge assembly 13 falls towards the ground, the frame assembly 12 will be impacted by the ground and deform inward. However, during the inward deformation process, the frame assembly 12 will come into contact with the support member 139. The support member 139 and the swing arm mechanism 132 are fastened together to form a whole. Since the elastic modulus of the support member 139 and the swing arm mechanism 132 is much higher than that of the frame assembly 12, the frame assembly 12 is supported by the support member 139 and the swing arm mechanism 132 when it deforms inward, so that the frame assembly 12 cannot deform further into the electronic device 1, thereby reducing the amount of deformation of the frame assembly 12.

[0066] like Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 , Figure 19 and Figure 20 As shown, according to some embodiments of this application, the hinge assembly 13 further includes: a slide rail 142, a first groove 141 is provided on the inner side of the slide groove 140, and the slide rail 142 is engaged in the first groove 141; a sliding member 148 is slidably connected to the slide rail 142, a second groove 134 is provided on the side wall of the pin 133, and the sliding member 148 is disposed in the second groove 134; wherein, during the rotation of the swing arm mechanism 132 relative to the base 131, the pin 133 drives the sliding member 148 to slide along the slide rail 142.

[0067] Specifically, the hinge assembly 13 also includes a slide rail 142 and a slider 148. The slider 148 and the slide rail 142 are slidably connected, and the slider 148 can slide along the slide rail 142. The inner wall of the slide groove 140 of the support member 139 is provided with a first groove 141, and the slide rail 142 is disposed in the first groove 141. The side wall of the pin 133 is provided with a second groove 134, and the slider 148 is disposed in the second groove 134. Thus, during the rotation of the swing arm mechanism 132 relative to the base 131, the pin 133 drives the slider 148 to slide along the slide rail 142, and the support member 139 and the swing arm mechanism 132 are movably connected through the slide rail 142 and the slider 148.

[0068] The slider 148 and the slide rail 142 are clearance fit, thereby providing a margin of movement for the swing arm mechanism 132.

[0069] like Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 , Figure 19 and Figure 20 As shown, according to some embodiments of this application, the slide rail 142 includes a first track 143 and a second track 144, which are respectively located on both sides of the pin 133. The first track 143 is fitted with at least one sliding member 148, and the second track 144 is fitted with at least one sliding member 148. The pin 133 is provided with at least two second grooves 134, some of which are opposite to the first track 143, and others are opposite to the second track 144. During the rotation of the swing arm mechanism 132 relative to the base 131, the pin 133 drives some of the sliding members 148 to slide along the first track 143, and the pin 133 drives another part of the sliding members 148 to slide along the second track 144.

[0070] Specifically, the slide rail 142 includes a first track 143 and a second track 144, which are respectively disposed on both sides of the pin 133. The pin 133 is provided with at least two second grooves 134, some of which are disposed opposite to the first track 143, and others are disposed opposite to the second track 144. At least one sliding member 148 is sleeved on the first track 143. The sliding member 148 on the first track 143 is disposed in at least one second groove 134 on one side of the pin 133, and the sliding member 148 on the second track 144 is disposed in at least one second groove 134 on the other side of the pin 133. Thus, the sliding member 148 on the first track 143 and the sliding member 148 on the second track 144 clamp the pin 133 on both sides, thereby reducing the possibility of the pin 133 disengaging from the slide groove 140 and improving the reliability of the cooperation of the various components in the hinge assembly 13.

[0071] The support member 139 and the swing arm mechanism 132 are fastened together by a sliding member 148. The sliding member 148 is sleeved on the slide rail 142, and the two sliding members 148 and the slide rail 142 are embedded in the support member 139. The swing arm mechanism 132 has a second groove 134, which is fastened to the sliding member 148 to form a lock, so that the swing arm mechanism 132 and the support member 139 are fixed in the first direction Y. This means that when the support member 139 is impacted by the frame assembly 12 along the first direction Y, due to the small gap between the support member 139 and the swing arm mechanism 132, the impact force on the support member 139 is preferentially transmitted to the swing arm mechanism 132.

[0072] The slider 148 is provided with a through hole and passes through the slide rail 142.

[0073] like Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 , Figure 19 and Figure 20 As shown, according to some embodiments of this application, one end of the first track 143 is connected to one end of the second track 144, and the other end of the first track 143 and the other end of the second track 144 form a break 145; the slide rail 142 is disposed in the first groove 141.

[0074] Specifically, one end of the first track 143 is connected to one end of the second track 144, the other end of the first track 143 and the other end of the second track 144 form a break 145, and the slide rail 142 is disposed in the first groove 141, that is, reducing the assembly difficulty of the slide rail 142 and the support member 139.

[0075] Optionally, the slide rail 142 is an elastic structure, which allows the slide rail 142 to be snapped into the first groove 141 through elastic deformation, thereby facilitating the assembly of the slide rail 142.

[0076] The slide rail 142 has an open ring structure, which allows it to engage with the first groove 141 through its own elasticity, reducing the installation difficulty of the slide rail 142 and the support member 139. The slide rail 142 is provided with at least two sliding members 148, and the pin 133 is provided with at least two second grooves 134 on its periphery. One sliding member 148 is disposed in one second groove 134. Thus, the two sliding members 148 can prevent the pin 133 from contacting the support member 139 and the slide rail 142. The pin 133 can only contact the sliding members 148, thereby improving the smoothness of the sliding of the pin 133.

[0077] At least two second grooves 134 are evenly distributed on the periphery of the pin 133.

[0078] like Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 , Figure 19 and Figure 20As shown, according to some embodiments of this application, the second groove 134 includes a first part 135 and a second part 136. The size of the second part 136 is larger than the size of the first part 135. The first part 135 is used to position the slide rail 142, and the second part 136 provides sliding space for the slider 148.

[0079] Specifically, the second groove 134 includes a first part 135 and a second part 136. The size of the second part 136 is larger than that of the first part 135, so that the first part 135 can support and position the slide rail 142. The larger size of the second part 136 provides sliding space for the slider 148, so that the slider 148 can slide on the slide rail 142.

[0080] A slide rail 142 is provided on the support member 139, and a slider 148 is provided on the slide rail 142. The slide rail 142 has a partial break 145, forming an open annular structure. Pressing the slide rail 142 can deform the slide rail 142 so that the slide rail 142 can be embedded into the first groove 141 of the support member 139. The second groove 134 includes a first part 135 and a second part 136. The second part 136 is larger in size, which facilitates the sliding of the slider 148 in the first groove 141. At the same time, it can also limit the swing arm mechanism 132 and the support member 139 in the first direction Y and reduce the possibility of the slider 148 falling off.

[0081] As the movement trajectory of the swing arm mechanism 132 changes during the switching between the unfolded and folded states of the electronic device 1, the sliding member 148 and the swing arm mechanism 132 engage to form a whole during the switching between the unfolded and folded states. A slide rail 142 is provided inside the support member 139, allowing the sliding member 148 and the swing arm mechanism 132 to slide on the slide rail 142 of the support member 139. During the switching between the folded and unfolded states of the electronic device 1, the swing arm mechanism 132 itself also rotates, and the swing arm mechanism 132 performs a partial rotation around the sliding member 148.

[0082] like Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 10 As shown, according to some embodiments of this application, the hinge assembly 13 further includes: a fixing pin 149; a third groove 138 is provided on the edge of the screen support plate 137; a fourth groove 146 is provided on the edge of the support member 139; the third groove 138 and the fourth groove 146 are arranged opposite to each other; and the fixing pin 149 is disposed in the third groove 138 and the fourth groove 146 to connect the screen support plate 137 and the support member 139.

[0083] Specifically, the hinge assembly 13 also includes a fixing pin 149 for fixing the screen support plate 137 and the support member 139. The fixing pin 149 connects the screen support plate 137 and the support member 139, so that the screen support plate 137 and the support member 139 can rotate synchronously, and reduces the assembly difficulty of the screen support plate 137 and the support member 139.

[0084] The screen support plate 137 has a third groove 138 on its edge facing the support member 139, and the support member 139 has a fourth groove 146 on its edge facing the screen support plate. The third groove 138 and the fourth groove 146 are arranged opposite to each other. The fixing pin 149 is simultaneously arranged in the third groove 138 and the fourth groove 146, thereby connecting the screen support plate 137 and the support member 139, so that at least a part of the support member 139 and the screen support plate 137 are located in the same plane, thereby providing better support for the first screen assembly 11.

[0085] A portion of the fixing pin 149 is embedded in the screen support plate 137, and another portion of the fixing pin 149 is embedded in the support member 139, thereby improving the connection strength between the screen support plate 137 and the support member 139.

[0086] Among them, the fixing pin 149 can be dovetail-shaped, figure-eight-shaped, or column-shaped, etc.

[0087] The support member 139 and the screen support plate 137 are fastened by the fixing pin 149. The support member 139 and the screen support plate 137 are provided with irregular groove structures at the corresponding positions of the fixing pin 149 to facilitate the cooperation with the fixing pin 149. Since the screen support plate 137 is a movable part, and since the support member 139 and the screen support plate 137 are fixed, when the swing arm mechanism 132 moves, it drives the movement of the support member 139, and the support member 139 drives the movement of the screen support plate 137. This reduces the possibility of discontinuous movement of the support member 139 and the screen support plate 137, and reduces the possibility of abnormal creases in the first screen assembly 11.

[0088] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, according to some embodiments of this application, the base 131 is provided with buckles 17 on both sides, and the buckles 17 are located on one side of the first screen assembly 11; wherein, the buckles 17 span across the first frame 121 and the second frame 124, the first frame 121 includes a first border 122, which is located on the outside of the first screen assembly 11, the second frame 124 includes a second border 125, which is located on the outside of the first screen assembly 11, and the support member 139 is disposed opposite to the first border 122 or the second border 125.

[0089] Specifically, since the first frame 121 and the second frame 124 need to provide space for the hinge assembly 13 to rotate, the first side frame 122 of the first frame 121 and the second side frame 125 of the second frame 124 cannot be connected. Therefore, buckles 17 need to be set at both ends of the base 131 to protect the first screen assembly 11 and the hinge assembly 13.

[0090] The buckle 17 spans across the first frame 121 and the second frame 124. The first frame 122 of the first frame 121 is located on the outside of the first screen assembly 11, and the second frame 125 of the second frame 124 is located on the outside of the first screen assembly 11. The buckle 17 avoids at least a portion of the support member 139. The support member 139 is disposed opposite to the first frame 122 or the second frame 125, so that the support member 139 can support the first frame 122 or the second frame 125. Therefore, when the electronic device 1 is dropped, the support member 139 can provide support for the first frame 122 or the second frame 125 with the help of the screen support plate 137 and the swing arm mechanism 132, reducing the possibility of deformation of the first frame 122 or the second frame 125.

[0091] By adding support in certain areas, the possibility of the buckle 17 impacting the first screen assembly 11 is also effectively reduced, thus optimizing the reliability of the first screen assembly 11. In the context of the increasing demand for thinner electronic devices 1, this provides another option for improving the reliability of the first screen assembly 11.

[0092] In related technologies, the latch does not avoid the hinge. The electronic device 1 provided in this application embodiment supports the frame assembly 12 by the support member 139 passing over the latch 17, thereby improving the reliability of the electronic device 1.

[0093] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, according to some embodiments of this application, a first protrusion 147 is provided on the side of the support member 139 away from the screen support plate 137, and a buckle 17 covers part of the surface of the support member 139. Part of the buckle 17 is located between the first screen assembly 11 and the first protrusion 147, and the first protrusion 147 is disposed opposite to the first frame 122 or the second frame 125.

[0094] Specifically, the support member 139 has a first protrusion 147 on the side away from the screen support plate 137, and the buckle 17 covers part of the surface of the support member 139. The buckle 17 avoids the first protrusion 147. The first protrusion 147 is located on the side of the buckle 17 away from the first screen assembly 11, so that the first protrusion 147 can pass over the buckle 17 to support the first frame 122 or the second frame 125. The support member 139 can support the first frame 122 or the second frame 125 without affecting the buckle 17.

[0095] The support member 139 and the swing arm mechanism 132 are fastened together to form a whole. The buckle 17 makes partial clearance to allow the first protrusion 147 of the support member 139 to extend, so that when the frame assembly 12 is impacted, it can contact the first protrusion 147 of the support member 139 to complete the force transmission.

[0096] like Figure 21 , Figure 22 , Figure 23 , Figure 24 , Figure 25 , Figure 26 and Figure 27 As shown, according to some embodiments of this application, the hinge assembly 13 further includes: a frame bracket 151, at least a portion of which is located on the side of the screen support plate 137 away from the first screen assembly 11; wherein, the frame bracket 151 includes a plurality of second protrusions 152, the first frame 121 includes a first plate 123 located on the side of the frame bracket 151 away from the first screen assembly 11, the second frame 124 includes a second plate 126 located on the side of the frame bracket 151 away from the first screen assembly 11, and the plurality of second protrusions 152 are embedded in the first plate 123 or the second plate 126.

[0097] Specifically, the hinge assembly 13 also includes a frame bracket 151, at least a portion of which is located on the side of the screen support plate 137 away from the first screen assembly 11, and the frame bracket 151 and the swing arm mechanism 132 rotate synchronously.

[0098] The frame support 151 includes a plurality of second protrusions 152. The first frame 121 includes a first plate 123 located on the side of the frame support 151 away from the first screen assembly 11. The second frame 124 includes a second plate 126 located on the side of the frame support 151 away from the first screen assembly 11. The plurality of second protrusions 152 are embedded in the first plate 123 or the second plate 126, thereby constraining the first plate 123 or the second plate 126, reducing the possibility of deformation of the first plate 123 or the second plate 126, thereby further reducing the possibility of deformation of the frame assembly 12 and improving the reliability of the electronic device 1.

[0099] That is, by binding the first frame 121 or the second frame 124 to the frame support 151, the strength of the first frame 121 or the second frame 124 is improved by combining two different metal materials. This reduces the local deformation of the first frame 121 or the second frame 124 by requiring the frame support 151 to deform in order to deform the first frame 121 or the second frame 124. By providing a second protrusion 152 on the frame bracket 151, the second protrusion 152 is fixedly connected to the first frame 121 or the second frame 124. The second protrusion 152 and the first plate 123 or the second plate 126 can be connected by welding, thereby combining the first plate 123 or the second plate 126 with the hinge assembly 13. This reduces the possibility that the first plate 123 or the second plate 126 will deform due to the impact energy acting on the weak points of the first plate 123 or the second plate 126 when it is subjected to impact. This also reduces the possibility that the first screen assembly 11 or the second screen assembly 16 will crack due to external tension because of the deformation of the weak points of the first plate 123 or the second plate 126.

[0100] like Figure 21 , Figure 22 , Figure 23 , Figure 24 , Figure 25 , Figure 26 and Figure 27As shown, the electronic device 1 provided in this embodiment of the application has a second protrusion 152 on the frame support 151 of the hinge assembly 13. The second protrusion 152 cooperates with the first plate 123 or the second plate 126, and the first plate 123 or the second plate 126 is fixedly connected to the frame support 151 through a welding process. This means that when the first plate 123 or the second plate 126 is impacted near the corner of the hinge assembly 13, if the first plate 123 or the second plate 126 is about to arch and deform, the fixed connection between the first plate 123 or the second plate 126 and the frame support 151 causes the first plate 123 or the second plate 126 to be pulled by the frame support 151, thereby reducing the possibility of the first plate 123 or the second plate 126 arching and deforming, and thus reducing the possibility of the first screen assembly 11 or the second screen assembly 16 cracking due to the arching and deformation of the frame assembly 12.

[0101] Optionally, the frame bracket 151 is provided with five second protrusions 152, and the first plate 123 or the second plate 126 is provided with five holes. The frame bracket 151 and the first plate 123 or the second plate 126 form an assembly structure of second protrusions 152 and holes. After assembly, since the frame bracket 151 and the first plate 123 or the second plate 126 are two different metal materials, the two parts can be fixed together by a specific riveting and welding process on the assembly line, thus forming a whole. The frame bracket 151 is made of metal, and its elastic modulus is higher than that of the metal of the frame assembly 12. The combination of the two is equivalent to thickening the frame assembly 12 during deformation, and strengthening the frame assembly 12 with a metal of higher elastic modulus. This results in greater resistance when the inner side of the frame assembly 12 is subjected to compression and bending, thereby achieving the purpose of preventing deformation.

[0102] The frame support 151 has two parts, which are respectively connected to the first plate 123 and the second plate 126. Both frame supports 151 are provided with a second protrusion 152, or only one of the two frame supports 151 is provided with a second protrusion 152.

[0103] To meet the demand for an ultra-thin and lightweight electronic device 1, the internal structural components are improved by using stronger components to enhance weaker components, thereby achieving a balance in product strength and effectively solving the deformation of the frame assembly 12. This also addresses a series of chain reactions caused by the deformation of the frame assembly 12, such as cracking of the second screen assembly 16, impact of the buckle 17 against the first screen assembly 11, delamination of the second screen assembly 16, and liquid ingress into the electronic device 1.

[0104] like Figure 21 , Figure 22 , Figure 23 , Figure 24 , Figure 25 , Figure 26and Figure 27 As shown, according to some embodiments of this application, the electronic device 1 further includes: a second screen assembly 16, which is disposed on the side of the first frame 121 away from the first screen assembly 11; wherein, there are two swing arm mechanisms 132 and two screen support plates 137, which are respectively disposed corresponding to the first frame 121 and the second frame 124, and the support members 139 are disposed on both sides of the screen support plate 137 in the first frame 121.

[0105] Specifically, the electronic device 1 also includes a second screen assembly 16 disposed on the side of the first frame 121 opposite to the first screen assembly 11.

[0106] There are two swing arm mechanisms 132 and two screen support plates 137. One swing arm mechanism 132 and one screen support plate 137 are disposed in the first frame 121, and the other swing arm mechanism 132 and the other screen support plate 137 are disposed in the second frame 124. Support members 139 are disposed on both sides of the screen support plate 137 of the first frame 121, thereby reducing the possibility of deformation of the first frame 121 and squeezing the second screen assembly 16. Furthermore, setting support members 139 at only both ends of one swing arm mechanism 132 can reduce the cost of electronic device 1 while reducing the deformation of frame assembly 12.

[0107] When the electronic device 1 is in a folded state, if the end of the hinge assembly 13 falls towards the ground, the frame assembly 12 will be impacted by the ground and deform inward. However, during the inward deformation process, the frame assembly 12 will come into contact with the support member 139. The support member 139 and the swing arm mechanism 132 are fastened together to form a whole. Since the elastic modulus of the support member 139 and the swing arm mechanism 132 is much higher than that of the frame assembly 12, the frame assembly 12 is supported by the support member 139 and the swing arm mechanism 132 when it deforms inward. This prevents the frame assembly 12 from deforming further into the electronic device 1, thereby reducing the amount of deformation of the frame assembly 12 and reducing the possibility of cracking of the second screen assembly 16 due to excessive external surface tension caused by the deformation of the frame assembly 12.

[0108] By optimizing the space of multiple components within the electronic device 1, the material selection of the frame assembly 12 can be more flexible, effectively reducing the deformation of the frame assembly 12 during cumulative drops. This reduces the tensile stress on the outer surface of the second screen assembly 16 due to the deformation of the frame assembly 12, thereby reducing the possibility of cracking of the second screen assembly 16.

[0109] In this application embodiment, electronic device 1 can be a terminal or other devices besides a terminal. For example, electronic device 1 can be a mobile phone, tablet computer, laptop computer, or PDA, etc.
