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, electronic devices include a hinge mechanism and a frame. The hinge mechanism includes a synchronous swing arm, a virtual swing arm, and a frame support. Both the synchronous swing arm and the virtual swing arm are connected to the frame of the electronic device through the frame support. Applying external force to both ends of the frame causes the frame to move the synchronous swing arm and the virtual swing arm via the frame support. The movement of the virtual swing arm pushes the frame upwards, expanding the space for accommodating the foldable screen of the electronic device. The movement of the synchronous swing arm meets the opening and closing requirements of the foldable screen. However, the hinge mechanism has many components, is complex to assemble, has high production costs, is heavy, and results in a poor user experience. Summary of the Invention

[0003] This application aims to provide an electronic device that at least solves the technical problems of hinge mechanisms in the related art, such as numerous components, complex assembly, high production costs, and heavy weight.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] On one hand, this application proposes an electronic device, which includes two frames and a hinge mechanism. The two frames are configured to be in an unfolded state and a folded state through the hinge mechanism. The hinge mechanism includes: a bracket; a first hinge part and a second hinge part, which are disposed on both sides of the bracket. Either the first hinge part and the second hinge part includes: a cam, which is disposed on the bracket; a guide rod, the first end of which abuts against the cam, and the second end of which is connected to a frame. During the switching between the folded state and the unfolded state, the first end of the guide rod slides along the outer contour of the cam.

[0006] In embodiments of this application, the electronic device includes two frames and a hinge mechanism. The hinge mechanism includes a first hinge portion and a second hinge portion of a bracket, which are disposed on both sides of the bracket, and either the first hinge portion or the second hinge portion is connected between the bracket and a frame.

[0007] Either the first hinge portion or the second hinge portion includes a cam and a guide rod, the guide rod including a first end and a second end.

[0008] The cam is mounted on the bracket, which serves as the mounting carrier for the cam and has the function of supporting and fixing the cam. The cam is fixedly connected to the bracket and cannot move with the frame.

[0009] The first end of the guide rod abuts against the cam and can slide along the outer contour of the cam. The second end of the guide rod is connected to a frame, for example, the second end of the guide rod is fixedly connected to a frame.

[0010] When folding the two frames, an external force is applied to both frames, causing the frames to slide along the cam until the first end of the guide rod moves to the first position. When unfolding the two frames, an external force is applied to both frames, causing the frames to slide along the cam until the first end of the guide rod moves to the second position.

[0011] Specifically, when the two frames are folded, the guide rod slides along the cam. The movement of the guide rod pushes the frames upward, thereby expanding the space for accommodating the foldable screen of the electronic device. Furthermore, the sliding of the guide rod along the cam allows the two frames to rotate relative to the support, thus meeting the folding requirements of the foldable screen.

[0012] Specifically, when the two frames are unfolded, the guide rod slides along the cam, which can meet the usage requirements of the two frames rotating relative to the bracket, and can realize the unfolding of the folding screen.

[0013] In other words, the bracket, cam, guide rod, and frame work together to meet both the opening and closing requirements of the two frames and the need to increase the screen storage space. Furthermore, this design simplifies the components of the hinge mechanism, resulting in a simpler structure, higher assembly and disassembly efficiency, lower production costs, and reduced hinge weight, thus improving overall product manufacturing costs.

[0031] The following is combined with Figures 1 to 9 This application describes an electronic device 200 according to an embodiment of the present application.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, according to some embodiments of this application, an electronic device 200 includes two frames 210 and a hinge mechanism 100. The two frames 210 are configured to be in an unfolded state and a folded state via the hinge mechanism 100. The hinge mechanism 100 includes: a bracket 110; a first hinge portion 120 and a second hinge portion 121, which are disposed on both sides of the bracket 110. Either the first hinge portion 120 or the second hinge portion 121 includes: a cam 122 disposed on the bracket 110; and a guide rod 124, the first end 126 of which abuts against the cam 122, and the second end 128 of which is connected to one of the frames 210. During the switching between the folded state and the unfolded state, the first end 126 of the guide rod slides along the outer contour of the cam 122.

[0033] In this embodiment, the electronic device 200 includes two frames 210 and a hinge mechanism 100. The hinge mechanism 100 includes a first hinge portion 120 and a second hinge portion 121 of a bracket 110. The first hinge portion 120 and the second hinge portion 121 are disposed on both sides of the bracket 110, and either the first hinge portion 120 or the second hinge portion 121 is connected between the bracket 110 and a frame 210.

[0034] Either the first hinge portion 120 or the second hinge portion 121 includes a cam 122 and a guide rod 124, the guide rod 124 including a first end and a second end.

[0035] The cam 122 is mounted on the bracket 110. That is, the bracket 110 serves as the mounting carrier for the cam 122 and has the function of supporting and fixing the cam 122. The cam 122 is fixedly connected to the bracket 110 and cannot move with the frame 210.

[0036] The first end 126 of the guide rod abuts against the cam 122, and the first end 126 of the guide rod can slide along the outer contour of the cam 122. The second end 128 of the guide rod is connected to a frame 210, for example, the second end 128 of the guide rod is fixedly connected to a frame 210.

[0037] When folding the two frames 210, an external force is applied to the two frames 210, causing the frames 210 to slide along the cam 122 until the first end 126 of the guide rod moves to the first position. When unfolding the two frames 210, an external force is applied to the two frames 210, causing the frames 210 to slide along the cam 122 until the first end 126 of the guide rod moves to the second position.

[0038] Specifically, when the two frames 210 are folded, the guide rod 124 slides along the cam 122. The movement of the guide rod 124 can push the frames 210 upward to expand the space for accommodating the foldable screen 230 of the electronic device 200. Furthermore, the sliding of the guide rod 124 along the cam 122 can meet the usage requirements of the two frames 210 rotating relative to the bracket 110, and can meet the folding usage requirements of the foldable screen 230.

[0039] Specifically, when the two frames 210 are unfolded, the guide rod 124 slides along the cam 122, which can meet the usage requirements of the two frames 210 rotating relative to the bracket 110, and can realize the unfolding of the folding screen 230.

[0040] In other words, the bracket 110, cam 122, guide rod 124, and frame 210 work together to meet both the opening and closing requirements of the two frames 210 and the need to increase the screen storage space. Furthermore, this design simplifies the components of the hinge mechanism 100, resulting in a simpler mechanism, higher assembly and disassembly efficiency, lower production costs, and reduced weight of the hinge mechanism 100, thus improving overall product manufacturing costs.

[0041] In some embodiments, in the folded state, the first end 126 of the guide rod moves along the cam 122 to a first position; in the unfolded state, the first end 126 of the guide rod moves along the cam 122 to a second position; along the first direction, the first position is closer to the middle of the bracket 110 than the second position; along the second direction, the second position is closer to the bottom 112 of the bracket than the first position, and the first direction is perpendicular to the second direction.

[0042] When folding the two frames 210, an external force is applied to the two frames 210, causing the frames 210 to slide along the cam 122 until the first end 126 of the guide rod moves to the first position. When unfolding the two frames 210, an external force is applied to the two frames 210, causing the frames 210 to slide along the cam 122 until the first end 126 of the guide rod moves to the second position.

[0043] In the first direction, the first position is closer to the middle of the bracket 110 than the second position. In the second direction, the second position is closer to the bottom 112 of the bracket than the first position, and the first direction is perpendicular to the second direction.

[0044] Specifically, when folding the two frames 210, the guide rod 124 slides along the cam 122, and the first end 126 of the guide rod moves to a first position. The movement of the guide rod 124 can push the frames 210 upward to expand the space for accommodating the foldable screen 230 of the electronic device 200. Furthermore, the sliding of the guide rod 124 along the cam 122 can satisfy the rotation requirements of the two frames 210 relative to the bracket 110, and can satisfy the folding requirements of the foldable screen 230.

[0045] Specifically, when the two frames 210 are unfolded, the guide rod 124 slides along the cam 122, and the first end 126 of the guide rod moves to the second position, which can meet the usage requirements of the two frames 210 rotating relative to the bracket 110 and realize the unfolding of the folding screen 230.

[0046] It is understood that the electronic device 200 includes a foldable screen 230, which is disposed in two frames 210. When the two frames 210 are folded, the foldable screen 230 folds accordingly; when the two frames 210 are unfolded, the foldable screen 230 unfolds accordingly.

[0047] In this embodiment, the first direction is perpendicular to the second direction.

[0048] In some other embodiments, the angle between the first direction and the second direction is an acute angle.

[0049] In some other embodiments, the angle between the first direction and the second direction is an obtuse angle.

[0050] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the outer contour of the cam 122 includes a first arc segment 122a and a second arc segment 122b, which are arranged opposite to each other. The radius of the first arc segment 122a is smaller than the radius of the second arc segment 122b. In the folded state, the first end 126 of the guide rod moves to the first arc segment 122a, and in the unfolded state, the first end 126 of the guide rod moves to the second arc segment 122b.

[0051] In this embodiment, the outer contour of the cam 122 includes a first arc segment 122a and a second arc segment 122b, the radius of the first arc segment 122a being smaller than the radius of the second arc segment 122b. That is, by utilizing the shape characteristics of the cam 122 itself, when folding the two frames 210, the guide rod 124 can push the two frames 210 upward during its movement to expand the screen space.

[0052] Specifically, such as Figure 2 As shown, the first arc segment 122a and the second arc segment 122b are correspondingly arranged along the second direction. The first arc segment 122a is located above the second arc segment 122b, and the radius of the first arc segment 122a is smaller than the radius of the second arc segment 122b. The outer contour of the cam 122 also includes a transition section, which connects the first arc segment 122a and the second arc segment 122b, and the transition section is inclined.

[0053] Fold the two frames 210, and the first end 126 of the guide rod moves from the second arc segment 122b through the transition segment to the first arc segment 122a.

[0054] The two frames 210 are unfolded, and the first end 126 of the guide rod moves from the first arc segment 122a, through the transition segment, to the second arc segment 122b.

[0055] In some embodiments, such as Figures 1 to 4 As shown, either the first hinge portion 120 or the second hinge portion 121 further includes: a first guide rail 134, the first guide rail 134 being located around the guide rod 124, the first end of the first guide rail 134 being rotatably connected to the bracket 110, and the second end of the first guide rail 134 being connected to a frame 210.

[0056] In this embodiment, both the first hinge portion 120 and the second hinge portion 121 further include a first guide rail 134, which defines the mating structure of the first guide rail 134, the guide rod 124, the bracket 110, and the frame 210. Specifically, the first guide rail 134 is located on the periphery of the guide rod 124, the first end of the first guide rail 134 is rotatably connected to the bracket 110, and the second end of the first guide rail 134 is connected to a frame 210. That is, the first guide rail 134 is connected between the bracket 110 and the frame 210. When the frame 210 is opened and closed, the first guide rail 134 can rotate relative to the bracket 110 as the frame 210 rotates.

[0057] The first guide rail 134 is located around the guide rod 124. For example, the first guide rail 134 is provided with a guide hole, and the guide rod 124 passes through the guide hole.

[0058] The first guide rail 134 has the function of limiting the movement trajectory of the guide rod 124, ensuring that the first end 126 of the guide rod is in contact with the cam 122, so as to meet the use requirements of sliding connection between the guide rod 124 and the cam 122, and to meet the use requirements of effectively opening and closing the electronic device 200.

[0059] It is understandable that the second end of the first guide rail 134 is connected to a frame 210, and the rotation of the frame 210 can drive the first guide rail 134 to rotate.

[0060] In some embodiments, such as Figures 1 to 4 As shown, either the first hinge portion 120 or the second hinge portion 121 further includes an elastic portion 136, through which the second end of the first guide rail 134 and the frame 210 are connected; wherein, in the folded state, the elastic portion 136 is in a stretched state, and in the unfolded state, the elastic portion 136 is reset.

[0061] In this embodiment, the structure of the first hinge portion 120 and the second hinge portion 121 is further defined. Both the first hinge portion 120 and the second hinge portion 121 further include an elastic portion 136. The elastic portion 136 is connected to the second end of the first guide rail 134 and is connected to the frame 210.

[0062] When the two frames 210 are folded, the elastic part 136 is in a stretched state. When the two frames 210 are unfolded, the elastic part 136 returns to its original state, that is, the elastic part 136 is in its initial state. The elastic part 136 provides reliable structural support for the first guide rail 134 to effectively limit the movement trajectory of the guide rod 124.

[0063] Specifically, the elastic part 136 includes springs, retaining rings, etc., which will not be listed here.

[0064] Specifically, the number of elastic parts 136 can be one or more. When the number of elastic parts 136 is multiple, the multiple elastic parts 136 are arranged at intervals.

[0065] In some embodiments, such as Figures 5 to 8 As shown, either the first hinge portion 120 or the second hinge portion 121 further includes: a second guide rail 138, located on one side of the cam 122, the second guide rail 138 having a guide groove 140, the first end 126 of the guide rod extending into the guide groove 140; a shaft 142, passing through the cam 122 and the second guide rail 138, and the second guide rail 138 being rotatable around the shaft 142, the bottom of the guide groove 140 being located between the shaft 142 and the first end 126 of the guide rod.

[0066] In this embodiment, either the first hinge portion 120 or the second hinge portion 121 further includes a second guide rail 138 and a shaft 142.

[0067] The second guide rail 138 is located on one side of the cam 122, and the shaft 142 passes through the cam 122 and the second guide rail 138. The second guide rail 138 can rotate around the shaft 142.

[0068] The second guide rail 138 is provided with a guide groove 140, the first end 126 of the guide rod extends into the guide groove 140, and the bottom of the guide groove 140 is located between the shaft 142 and the first end 126 of the guide rod.

[0069] The second guide rail 138 has the function of limiting the movement trajectory of the guide rod 124, ensuring that the first end 126 of the guide rod is in contact with the cam 122, so as to meet the use requirements of sliding connection between the guide rod 124 and the cam 122, and to meet the use requirements of effectively opening and closing the electronic device 200.

[0070] Understandably, the shaft 142 passes through the cam 122 and the second guide rail 138. This arrangement limits the mating dimensions of the cam 122 and the second guide rail 138, and thus limits the mating dimensions of the guide rod 124 and the cam 122.

[0071] In some embodiments, the first end 126 of the guide rod is spherical.

[0072] In this embodiment, the structure of the guide rod 124 is further defined. Specifically, the first end 126 of the guide rod is spherical. This design ensures that the guide rod 124 is slidably connected to the cam 122 while reducing the contact area between the guide rod 124 and the cam 122. Therefore, it can reduce the resistance when the guide rod 124 moves, so that the guide rod 124 can move smoothly along the cam 122, and can ensure the smooth opening and closing of the electronic device 200.

[0073] In this embodiment, the guide rod 124 includes a main rod, a first end 126 of the guide rod, and a second end 128 of the guide rod, which are integrally formed.

[0074] In some other embodiments, the guide rod 124 includes a main rod, a first end 126 of the guide rod, and a second end 128 of the guide rod. The main rod is detachably connected to the first end 126 of the guide rod, and / or the main rod is detachably connected to the second end 128 of the guide rod.

[0075] In some embodiments, such as Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the outer contour of the cam 122 is formed with a cam groove 132, and the first end 126 of the guide rod includes a lug 130, which can slide within the cam groove 132.

[0076] In this embodiment, the mating structure of the cam 122 and the guide rod 124 is further defined. Specifically, the outer contour of the cam 122 is formed with a cam groove 132, and the first end 126 of the guide rod includes a lug 130, which is inserted into the cam groove 132 and can slide within the cam groove 132. That is, the lug 130 moves along the groove wall of the cam groove 132. Utilizing the shape characteristics of the cam groove 132 itself, when folding the two frames 210, the guide rod 124 can push the two frames 210 upwards during its movement to expand the screen space. This configuration enhances the mating structure of the cam 122 and the guide rod 124, ensuring the stability and reliability of the guide rod 124's movement along the cam 122 and preventing misalignment of the guide rod 124.

[0077] In this embodiment, as Figures 5 to 9 As shown, the cam groove 132 is an annular cam groove 132.

[0078] In some other embodiments, the cam groove 132 is an arc-shaped cam groove 132.

[0079] In this embodiment, the guide rod 124 is integrally formed with a lug 130.

[0080] In other embodiments, the guide rod 124 and the lug 130 are detachably connected, such as by plugging, snapping, screwing, etc., which will not be listed here.

[0081] In some embodiments, the lug 130 is cylindrical in shape.

[0082] In this embodiment, the shape of the lug 130 is further defined; specifically, the lug 130 is cylindrical. This design, while ensuring the sliding connection between the guide rod 124 and the cam 122, reduces the contact area between the guide rod 124 and the cam 122. Therefore, it can reduce the resistance when the guide rod 124 moves, allowing the lug 130 to move smoothly along the cam groove 132, thus ensuring the smooth opening and closing of the electronic device 200.

[0083] In other embodiments, the shape of the lug 130 includes conical, spherical, etc., which will not be listed here.

[0084] In some embodiments, such as Figures 1 to 8 As shown, the hinge mechanism 100 further includes: a hinge cover 150, disposed on the side of the bracket 110 away from the cam 122; a floating plate 160, located between the cam 122 of the first hinge portion 120 and the cam 122 of the second hinge portion 121; and an elastic element 170 connected between the floating plate 160 and the hinge cover 150. In the folded state, the hinge cover 150 exposes two frames 210; in the unfolded state, the hinge mechanism 100 is located inside the two frames 210.

[0085] In this embodiment, the hinge mechanism 100 further includes a hinge cover 150, which is connected to the bracket 110 and is located on the side of the bracket 110 away from the cam 122.

[0086] When the two frames 210 are folded, the hinge cover 150 protrudes from the two frames 210. The hinge cover 150 engages with the two frames 210 to cover the internal components of the electronic device 200. That is, the internal components of the electronic device 200 are not exposed through the area between the two frames 210, thus ensuring the aesthetic appearance of the electronic device 200.

[0087] When the two frames 210 are in the unfolded state, the hinge mechanism 100 is located inside the two frames 210, that is, the two frames 210 can enclose the area for accommodating the hinge mechanism 100.

[0088] The hinge mechanism 100 also includes a floating plate 160 and an elastic element 170. The floating plate 160 is connected to the hinge cover 150 via the elastic element 170. In the folded state, the folding screen 230 can press the floating plate 160 downward, and the elastic element 170 is compressed accordingly. In the unfolded state, the elastic element 170 and the floating plate 160 return to their original positions.

[0089] Specifically, the elastic element 170 includes compression springs, springs, etc., which will not be listed here.

[0090] Specifically, electronic device 200 can be a mobile terminal such as a mobile phone, wearable device, tablet computer, laptop computer, mobile computer, augmented reality device (also known as AR device), virtual reality device (also known as VR device), and handheld game console, etc.

[0091] In some embodiments, such as Figures 1 to 8 As shown, the electronic device 200 further includes: two frames 210, which are arranged at intervals along a first direction; a folding screen 230, which is disposed on the two frames 210; each frame 210 is provided with a recess 212, and the recesses 212 of the two frames 210 and the folding screen 230 enclose an installation area 220; when the two frames 210 are in the unfolded state, the hinge mechanism 100 is located within the installation area 220; when the two frames 210 are in the folded state, the hinge cover 150 exposes the two frames 210.

[0092] Specifically, the support 110 is an amorphous component.

[0093] Specifically, the hinge mechanism 100 includes a bracket 110, a first hinge portion 120, and a second hinge portion 121. Each hinge portion includes a cam 122, a guide rod 124, and a guide rail. The cam 122 is fixed to the bracket 110. The guide rod 124 is connected between a frame 210 and the cam 122. The guide rail limits the movement of the guide rod 124.

[0094] When the two frames 210 are in the folded state, the guide rod 124 rotates and moves upward along the surface contour of the cam 122, thereby realizing the flipping and upward movement of the frame 210 of the electronic device 200, increasing the screen space.

[0095] like Figures 1 to 4 As shown, two cams 122 are fixed to the bracket 110 and do not move with the frame 210. The first end of the first guide rail 134 is rotatably connected to the bracket 110, and the second end of the first guide rail 134 is connected to the frame 210 through two deformable springs. Therefore, when the two frames 210 are folded, the first guide rail 134 can rotate with the frames 210. When the two frames 210 are in the unfolded state, the springs are in the unfurled state. The first end 126 of the guide rod contacts the surface contour of the cam 122, and the second end 128 of the guide rod is fixedly connected to the frame 210. The first end 126 of the guide rod is spherical in shape.

[0096] When folding the two frames 210, an external force is applied to both ends of the frames 210. The frames 210 drive the guide rod 124 to rotate on the surface of the cam 122. The special outer contour of the cam 122 allows the guide rod 124 to push the frames 210 upward during rotation, expanding the screen space. Simultaneously, the frame 210 also drives the first guide rail 134 to rotate (with the point where the first guide rail 134 and the bracket 110 are rotatably connected as the center of rotation). The first guide rail 134 limits the guide rod 124, ensuring that the guide rod 124 and the cam 122 remain in contact. Since the first end of the first guide rail 134 is rotatably connected to the bracket 110, the frame 210 moves upward relative to it. Therefore, the other end of the first guide rail 134 is connected to the frame 210 via a spring, allowing for relative displacement between the first guide rail 134 and the frame 210. During folding, the spring is in a stretched state.

[0097] like Figures 5 to 8 As shown, two cams 122 are fixed to the bracket 110 and do not move with the frame 210. The outer surface of the cam 122 has a cam groove 132. The second end 128 of the guide rod is fixed to the frame 210, and the first end 126 of the guide rod has a cylindrical lug 130, which engages with the cam groove 132. One end of the second guide rail 138 has a through hole that engages with the shaft 142 on the cam 122. Therefore, when the two frames 210 are folded, the second guide rail 138 rotates around the shaft 142 on the cam 122 as its rotation center. The second guide rail 138 can accommodate the guide rod 124, thus restricting the degree of freedom of the guide rod 124 and limiting its rotation direction.

[0098] When folding the two frames 210, an external force is applied to both ends of the frames 210, causing the frames 210 to rotate and the guide rod 124 to rotate. The lugs 130 on the guide rod 124 move within the cam groove 132. The shape of the cam groove 132 allows the guide rod 124 to push the frames 210 upward during rotation, expanding the screen space. Simultaneously with the rotation of the frames 210, the second guide rail 138 also rotates (around the shaft 142). The second guide rail 138 limits the movement of the guide rod 124, ensuring its rotational trajectory, thus enabling the frames 210 to rotate and rise simultaneously during the folding process.
