Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to an electronic equipment. Background Art

[0002] Foldable phones are becoming increasingly popular due to their large display area and enhanced portability. In these devices, two adjacent housings are pivotally connected to a base via a swing arm, enabling relative rotation between the housings and enabling the electronic device to switch between unfolded and folded states.

[0003] In a foldable electronic device, although its display screen is a flexible structure, when the electronic device is in a folded state, the internal stress of the display screen will still produce an outward pushing effect. The aforementioned stress acts on the two adjacent shells and the base, causing the base and the two shells to move away from each other. In this case, a gap will be generated between the base and the two adjacent shells, making it easy for external dust and water vapor to invade the interior of the electronic device, thereby having a significant adverse effect on the service life of the electronic device. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide an electronic device to solve the problem that when the current electronic device is in a folded state, the internal stress of the display screen drives the base and the shell to move away from each other to form a gap, causing external dust and water vapor to easily invade the interior of the electronic device, thereby having a significant adverse effect on the service life of the electronic device.

[0005] An embodiment of the present application provides an electronic device, which includes a housing, a bracket, a base, a first swing arm, and a display screen, wherein: The housing and the bracket are provided on opposite sides of the base, any one of the brackets is fixedly connected to the corresponding housing, and the display screen is connected to each of the housings; A first swing arm is provided between each of the brackets and the base, and one end of each of the first swing arms is slidably connected to the bracket, and the other end of each of the first swing arms is rotatably connected to the base. At least one of the first swing arms is provided with a first limiting portion, and the first limiting portion is protrudingly provided on a side of the first swing arm that is away from the screen supporting side of the housing. The bracket is provided with a second limiting portion. When the electronic device is in an unfolded state, the first limiting portion and the second limiting portion are spaced apart from each other; when the electronic device is in a folded state, the first limiting portion abuts against the second limiting portion to limit the first swing arm from moving relative to the bracket toward the base in the sliding direction between the first swing arm and the bracket.

[0006] An embodiment of the present application discloses an electronic device, which includes a base, a shell and a bracket are provided on opposite sides of the base, and any bracket is fixedly connected to the corresponding shell. At the same time, a first swing arm is provided between any bracket and the shell, the first swing arm is rotatably connected to the base, and the first swing arm is slidably connected to the bracket, and the display screen is connected to each shell, so that during the relative rotation of the shells on opposite sides of the base, the display screen can be driven to deform, so that the display screen and the entire electronic device can switch between a folded state and an unfolded state.

[0007] At the same time, in the electronic device disclosed in the embodiment of the present application, at least one first swing arm is provided with a first limiting portion, and the bracket is provided with a second limiting portion, wherein the first limiting portion is protrudingly provided on a side of the first swing arm away from the screen supporting side of the shell, and when the electronic device is in the unfolded state, the first limiting portion and the second limiting portion are spaced apart, thereby ensuring that the first swing arm can still move relative to the bracket in the relative sliding direction between the first swing arm and the bracket, thereby enabling the electronic device to switch to the folded state normally; correspondingly, when the electronic device is in the folded state, the first limiting portion abuts against the second limiting portion, thereby limiting the first swing arm from continuing to move relative to the bracket toward the direction where the base is located in the sliding direction between the first swing arm and the bracket by the second limiting portion. In this case, the display screen of the electronic device in the folded state can be prevented from driving the base to move away from the shell in order to restore its own deformation, thereby ensuring that no gap is generated between the base and the shell in the folded state, preventing impurities such as dust and water vapor outside the electronic device from invading the interior of the electronic device, thereby improving the service life of the electronic device.

DETAILED DESCRIPTION

[0010] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0011] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0012] like Figures 1-11 As shown, the embodiment of the present application discloses an electronic device, which is specifically a foldable electronic device, that is, the electronic device has a folded state and an unfolded state, and can switch between the folded state and the unfolded state. Figure 1 As shown, the electronic device disclosed in the embodiment of the present application includes a housing 110, a bracket 120, a base 200, a first swing arm 310 and a display screen 3. Of course, the electronic device may also include other devices such as a second swing arm 320 and a hinge cover 500, wherein the hinge cover 500 is arranged on the outside of the base 200.

[0013] The base 200 is provided with a housing 110 and a bracket 120 on opposite sides, and each bracket 120 is fixedly connected to the corresponding housing 110. The brackets 120 on opposite sides of the base 200 are connected by a first swing arm 310, allowing the housings 110 on opposite sides of the base 200 to rotate relative to the base 200, thereby enabling the electronic device to switch between an unfolded state and a folded state. Accordingly, in the electronic device, the display screen 3 is connected to each housing 110, that is, the housings 110 on opposite sides of the base 200 are connected to the display screen 3. This allows the display screen 3 to bend and deform simultaneously during the rotation of the housing 110 relative to the base 200.

[0014] In which, the display screen 3 can be a flexible screen as a whole, or the display screen 3 can include a first part 31, a second part 32 and a third part 33, wherein the third part 33 is connected between the first part 31 and the second part 32, and the first part 31 and the second part 32 are respectively supported on two adjacent shells 110, the first part 31 and the second part 32 can be flexible structures or rigid structures, the third part 33 is opposite to the base 200, and the third part 33 is a flexible structure.

[0015] As described above, the housing 110 and the bracket 120 are provided on opposite sides of the base 200, and the housing 110 and the bracket 120 can be connected to the base 200 via the first swing arm 310. More specifically, the housing 110 and the bracket 120 are further connected to the base 200 via the second swing arm 320. In other words, the first swing arm 310 and the second swing arm 320 are typically provided on opposite sides of the base 200, and the bracket 120 is typically directly connected to the first swing arm 310 and the second swing arm 320. This allows the bracket 120 to bridge the gap and form a relatively stable assembly relationship between two adjacent housings 110.

[0016] Among them, the base 200 is the basic structure of the hinge mechanism, and other devices such as the first swing arm 310 can be directly or indirectly installed or connected to the base 200, so that the electronic device can form an integral structure and provide a rotational connection function for the two adjacent shells 110.

[0017] As described above, a first swing arm 310 is provided between each bracket 120 and the base 200. In the electronic device disclosed in the embodiment of the present application, one end of each first swing arm 310 is slidably connected to the bracket 120, and the other end of each first swing arm 310 is rotatably connected to the base 200. In a specific embodiment of the present application, a connecting device such as a rotating shaft can be used to form a more reliable rotational connection relationship between the first swing arm 310 and the base 200. Specifically, the base 200 and the first swing arm 310 can both be provided with an axis hole, and by having the rotating shaft correspondingly pass through the respective axis holes of the base 200 and the first swing arm 310, it can be ensured that the first swing arm 310 and the base 200 can form a stable rotational connection relationship through the rotating shaft.

[0018] Furthermore, in the electronic device disclosed in the embodiment of the present application, the bracket 120 may be provided with a first slide groove 121, and the first slide groove 121 extends in a direction perpendicular to the rotation direction of the first swing arm 310. A part of the first swing arm 310 away from the base 200 can be extended into the first slide groove 121, so that the first swing arm 310 and the bracket 120 form a reliable sliding fit relationship, and during the process of switching the electronic device between the folded state and the unfolded state, the first swing arm 310 can slide in the first slide groove 121 relative to the bracket 120.

[0019] In addition, as mentioned above, the electronic device further includes a second swing arm 320. In layman's terms, the base 200, the first swing arm 310, the second swing arm 320 and the hinge cover 500 can be considered as a hinge mechanism 1. Figure 11 As shown, housings 110 are provided on opposite sides of the hinge mechanism 1, and the two housings 110 can be connected to each other through the hinge mechanism 1. Of course, the hinge mechanism 1 can also generally include other components such as a bracket 120 and a damping mechanism, which will not be described here one by one.

[0020] For the second swing arm 320, its opposite ends form a rotational cooperation relationship with the bracket 120 and the base 200 respectively. Similarly, the second swing arm 320 can also be connected to the base 200 by a rotating shaft. In other embodiments of the present application, the second swing arm 320 can also be connected to the base 200 by an arc-shaped bearing structure. In this case, the rotation axis between the second swing arm 320 and the base 200 can be located outside the base 200, thereby increasing the relative rotation angle between the second swing arm 320 and the base 200, and when the electronic device is in a folded state, a flared structure facing the base 200 is formed between the second swing arms 320 on opposite sides of the base 200, which can increase the accommodation space of the corresponding position in the display screen 3 (that is, the above-mentioned third part 33), thereby reducing the deformation of the display screen 3 and improving the service life of the display screen 3.

[0021] As described above, during the operation of the electronic device, the shells 110 on both sides of the base 200 can rotate relative to each other, thereby causing the display screen 3 to deform. Although the display screen 3 (the middle part) is a flexible structure, when the electronic device is in the folded state, the middle part of the display screen 3 will still be affected by the internal stress and produce a tendency and movement to recover the deformation. Among them, the relative position stability between the two adjacent shells 110 in the electronic device in the folded state is relatively high. For this reason, the internal stress of the display screen 3 is more likely to act on the base 200, so that the base 200 moves in the direction of its own thickness away from the two shells 110. Movement, wherein, when the electronic device is in the folded state, the thickness direction of the base 200 is parallel to the relative sliding direction between the first swing arm 310 and the bracket 120, and then, in the process of the base 200 moving in the direction away from the shell 110, the first swing arm 310 rotatably connected to the base 200 will further slide relative to the bracket 120 fixedly connected to the shell 110, thereby causing gaps between the two side edges of the base 200 and the two adjacent shells 110, causing impurities such as dust and water vapor outside the electronic device to easily invade the interior of the electronic device, thereby adversely affecting the service life of the electronic device.

[0022] Based on the above problems, in the electronic device disclosed in the embodiment of the present application, if Figure 1As shown, at least one first swing arm 310 is provided with a first limiting portion 410, and the first limiting portion 410 is protrudingly arranged on the side of the first swing arm 310 that is away from the screen supporting side of the shell 110. Correspondingly, a second limiting portion 420 is provided on the bracket 120. The first limiting portion 410 and the second limiting portion 420 are used to limit each other in the direction of relative sliding between the first swing arm 310 and the bracket 120, so as to set the sliding end position of the first swing arm 310 relative to the bracket 120, thereby preventing the first swing arm 310 and the bracket 120 from sliding relative to each other in an uncontrolled manner, causing the display screen 3 to drive the base 200 to move relative to the shell 110, thereby causing a gap to be generated between the base 200 and the shell 110.

[0023] Optionally, when the electronic device is in the folded state, to ensure relatively high stability in the relative fixed state between the housing 110 and the base 200 on opposite sides of the base 200, in a further embodiment, first position-limiting portions 410 may be provided on each of the two first swing arms 310 located on opposite sides of the base 200, and second position-limiting portions 420 may be provided on each of the two brackets 120 located on opposite sides of the base 200. In this case, relatively high positional stability between the base 200 and two adjacent housings 110 can be ensured. Furthermore, multiple first swing arms 310 may be provided between the base 200 and any bracket 120. In this case, at least one first position-limiting portion 410 may be provided on each first swing arm 310, and second position-limiting portions 420 corresponding to the first position-limiting portions 410 may be provided at corresponding positions on the bracket 120, thereby maximizing the stability of the relative fixed state between the base 200 and the housing 110.

[0024] As described above, the display screen 3 can be interconnected with each shell 110. For this purpose, the shell 110 has the ability to support the display screen 3. In this case, the side of the shell 110 facing the display screen 3 is the screen supporting side of the shell 110. In more detail, the bracket 120 is fixedly installed on the screen supporting side of the shell 110, and the first swing arm 310 is slidably installed in the first slide groove 121 of the bracket 120. For this purpose, the side of the first swing arm 310 facing the shell 110 is the side of the first swing arm 310 facing away from the screen supporting side of the shell 110. More intuitively, as shown in the figure, in the electronic device in the folded state, the space clamped between the two first swing arms 310 on the opposite sides of the base 200 is used to accommodate the display screen 3, that is, the display screen 3 is located on the inner side of the two first swing arms 310, and correspondingly, the first limit portion 410 is located on the outer side of the first swing arm 310. In the electronic device disclosed in the embodiment of the present application, by setting the first limiting portion 410 on the aforementioned side of the first swing arm 310, the processing difficulty of the first limiting portion 410 and the second limiting portion 420 can be reduced. At the same time, by adopting the aforementioned technical solution, the overall size of the first swing arm 310 and the first limiting portion 410 in the rotation axis of the first swing arm 310 can be minimized, thereby expanding the installation space of the electronic device in its own length direction, which facilitates the development of foldable electronic devices towards lightweight and thinness.

[0025] Based on the electronic device structure described above, when the electronic device is in the unfolded state, the first limiting portion 410 can be spaced apart from the second limiting portion 420. Specifically, the first limiting portion 410 and the second limiting portion 420 are spaced apart from each other in the aforementioned sliding direction, thereby ensuring that the first limiting portion 410 can slide relative to the bracket 120 (and the second limiting portion 420) along with the first swing arm 310, thereby enabling the electronic device to switch to the folded state. Accordingly, during the process of switching the electronic device from the unfolded state to the folded state, the first limiting portion 410 gradually moves toward the second limiting portion 420. When the electronic device is in the folded state, the first limiting portion 410 abuts against the second limiting portion 420, thereby restricting the first swing arm 310 from moving relative to the bracket 120 toward the base 200 in the sliding direction between the first swing arm 310 and the bracket 120.

[0026] Specifically, both the first limiting portion 410 and the second limiting portion 420 can have a strip-shaped or block-shaped structure, and the first limiting portion 410 can be formed during the processing of the first swing arm 310. Similarly, the second limiting portion 420 can also be formed during the processing of the bracket 120 to improve the connection reliability between the first limiting portion 410 and the first swing arm 310, and between the second limiting portion 420 and the bracket 120. Furthermore, other parameters such as the dimensions of the first limiting portion 410 and the second limiting portion 420 are not limited herein.

[0027] An embodiment of the present application discloses an electronic device, which includes a base 200, wherein a shell 110 and a bracket 120 are provided on opposite sides of the base 200, and any bracket 120 is fixedly connected to the corresponding shell 110. At the same time, a first swing arm 310 is provided between any bracket 120 and the shell 110, and the first swing arm 310 is rotatably connected to the base 200, and the first swing arm 310 is slidably connected to the bracket 120. The display screen 3 is connected to each shell 110, so that during the relative rotation of the shells 110 on opposite sides of the base 200, the display screen 3 can be driven to deform, so that the display screen 3 and the entire electronic device can switch between a folded state and an unfolded state.

[0028] At the same time, in the electronic device disclosed in the embodiment of the present application, at least one first swing arm 310 is provided with a first limiting portion 410, and the bracket 120 is provided with a second limiting portion 420, wherein the first limiting portion 410 is protrudingly arranged on a side of the first swing arm 310 that is away from the screen supporting side of the shell 110, and when the electronic device is in the unfolded state, the first limiting portion 410 and the second limiting portion 420 are spaced apart, thereby ensuring that the first swing arm 310 can still move relative to the bracket 120 in the relative sliding direction between the first swing arm 310 and the bracket 120, thereby enabling the electronic device to switch to the folded state normally; correspondingly, when the electronic device is in the folded state, In this case, the first limiting portion 410 abuts against the second limiting portion 420, so that in the sliding direction between the first swing arm 310 and the bracket 120, the second limiting portion 420 limits the first swing arm 310 from continuing to move relative to the bracket 120 toward the direction where the base 200 is located. In this case, the display screen 3 of the electronic device in the folded state can be prevented from driving the base 200 to move away from the shell 110 in order to restore its own deformation, thereby ensuring that no gap is generated between the base 200 and the shell 110 in the folded state, preventing impurities such as dust and water vapor outside the electronic device from invading the interior of the electronic device, thereby improving the service life of the electronic device.

[0029] As described above, the back of the first swing arm 310 is provided with a first limiting portion 410, and the bracket 120 is provided with a second limiting portion 420. At the same time, the bracket 120 is provided with a first sliding groove 121. Therefore, in a specific embodiment of the present application, the first sliding groove 121 can be further provided with another groove extending along the aforementioned sliding direction on the groove wall close to the housing 110, and after the first swing arm 310 is installed in the first sliding groove 121, a second limiting portion 420 is provided at the end of the groove, so that when the electronic device is automatically unfolded, the second limiting portion 420 is provided. During the process of switching the state to the folded state, the first swing arm 310 can slide in the first slide groove 121, and the first limiting portion 410 can slide in the aforementioned groove. Correspondingly, when the electronic device is switched to the folded state, the first limiting portion 410 can slide to the end of the groove, and the first limiting portion 410 abuts against the second limiting portion 420 to limit the first limiting portion 410 from continuing to slide relative to the bracket 120. At the same time, the first swing arm 310 can also be synchronously limited from continuing to slide along the first slide groove 121.

[0030] In order to reduce the overall processing difficulty of the bracket 120 and the second limiting portion 420, in another embodiment of the application, as shown in FIG. Figure 1 As shown, in addition to the first slide groove 121, the bracket 120 is also provided with an opening 123, and the opening 123 is communicated with the first slide groove 121. As above, the first swing arm 310 is slidably installed in the first slide groove 121, and in the embodiment of the present application, the opening 123 is arranged on the side of the first slide groove 121 away from the screen support surface of the shell 110. In this case, the overall size of the first swing arm 310 and the bracket 120 in the thickness direction of the first swing arm 310 can be reduced, which is further conducive to the development of electronic equipment towards lighter and thinner directions.

[0031] Of course, in the case of adopting the above technical solution, in order to ensure that the first swing arm 310 can be normally installed in the first sliding groove 121, as shown in FIG. Figure 1 As shown, in the sliding direction of the first swing arm 310 and the bracket 120, the opening 123 extends from one side of the bracket 120 close to the base 200 to the other side, and along the rotation axis of the first swing arm 310, the second limiting portion 420 protrudes into the opening 123. In this case, the first limiting portion 410 arranged on the side of the first swing arm 310 away from the screen supporting side of the shell 110 can cooperate with the second limiting portion 420 protruding in the opening 123 to limit the sliding direction.

[0032] In the above technical solution, it is necessary to make the dimensions of the first slide groove 121 and the first swing arm 310 in the thickness direction of the first swing arm 310 comparable, so as to ensure that when the first swing arm 310 slides along the first slide groove 121, the first limiting portion 410 can normally limit each other with the second limiting portion 420 in the sliding direction.

[0033] In addition, when the above technical solution is adopted, when the first swing arm 310 and the bracket 120 are assembled with each other when necessary, the first swing arm 310 can be first installed in the first slide groove 121 at an angle. During this process, the first limiting portion 410 can move inward from the opening 123. Thereafter, after the first limiting portion 410 moves from the opening 123 to the side of the second limiting portion 420 away from the base 200, the first swing arm 310 is straightened so that the first swing arm 310 and the first slide groove 121 form a corresponding sliding fit relationship.

[0034] In the above embodiment, the back side of the bracket 120 is provided with an opening 123 connected to the first slide groove 121. In order to ensure that the sliding fit between the first swing arm 310 and the first slide groove 121 is relatively stable, in the process of forming the opening 123, along the rotation axis of the first swing arm 310, it is necessary to prevent the extension dimensions of the opposite ends of the opening 123 from being too large, so as to ensure that the first swing arm 310 can form a relatively stable fit relationship with the opposite sides of the first slide groove 121 on both sides of its own rotation axis.

[0035] Based on the above situation, in order to further improve the stability of the limiting cooperation relationship between the first swing arm 310 and the bracket 120 in the electronic device in the folded state, optionally, as Figure 1 As shown, and combined Figure 2 and Figure 3 In the rotational axis direction, second limiting portions 420 can be provided on opposite sides of the opening 123, and each second limiting portion 420 can protrude inward from the edge of the opening 123. Correspondingly, in the embodiment of the present application, two first limiting portions 410 are also provided on the side of the first swing arm 310 corresponding to the aforementioned opening 123, which is away from the screen-supporting side of the housing 110. The two second limiting portions 420 correspond to the two first limiting portions 410 in a one-to-one manner.

[0036] When the above technical solution is adopted, since the two first limiting portions 410 provided on the back of the same first swing arm 310 are spaced apart from each other in the aforementioned rotation axis direction, the two first limiting portions 410 on the back of the first swing arm 310 are respectively limited to the two corresponding second limiting portions 420 on the bracket 120, which can further improve the stability of the limiting cooperation relationship between the first swing arm 310 and the bracket 120. At the same time, it can also prevent the base 200 from driving one side of the first swing arm 310 to move when the base 200 is subjected to the internal stress of the display screen 3, causing the first swing arm 310 to tilt relative to the first slide groove 121.

[0037] Based on the above embodiment, when two second limiting portions 420 spaced apart from each other along the rotation axis of the first swing arm 310 are provided at the opening 123, in order to further reduce the difficulty of assembling the first swing arm 310 and the bracket 120, optionally, as shown in FIG. Figure 1 As shown, in the sliding direction of the first swing arm 310 and the bracket 120, the two first limiting portions 410 arranged on one side of the first swing arm 310 can be spaced apart, and accordingly, the two second limiting portions 420 arranged at the opening 123 are also spaced apart. In this case, the straight-line distance between the two second limiting portions 420 can be increased, which facilitates the assembly work between the first swing arm 310 and the bracket 120.

[0038] Of course, it should be noted that in the process of designing electronic equipment, the distance between the two first limiting portions 410 on the back of the same first swing arm 310 in the aforementioned sliding direction cannot be too large, so as to minimize the size of the first swing arm 310 in the aforementioned sliding direction, thereby reducing the space occupied by the first swing arm 310 and the bracket 120 on the opposite sides of the base 200 in the aforementioned sliding direction.

[0039] In the above embodiment, when assembling the first swing arm 310 and the bracket 120, the first swing arm 310 having two first limiting portions 410 on the back and the bracket 120 can be tilted relative to each other, so that the two first limiting portions 410 can pass through the gap between the two second limiting portions 420, thereby ensuring that the first swing arm 310 and the bracket 120 can complete the mutual assembly work normally.

[0040] In another embodiment of the present application, the first swing arm 310 can also include a first arm body 311 and a second arm body 312 that are separately arranged, and the first arm body 311 and the second arm body 312 are spaced apart from each other in the rotation axis of the first swing arm 310. At the same time, the first arm body 311 and the second arm body 312 are both slidingly matched with the same first slide groove 121 on the bracket 120, which can also ensure that the first arm body 311 and the second arm body 312 have good consistency during the rotation relative to the base 200, and further improve the stability of the sliding matching relationship between the first swing arm 310 and the bracket 120.

[0041] When the electronic device is assembled using the above technical solution, the first arm 311 and the second arm 312 can be installed sequentially. During the installation process, the first arm 311 can be extended into the opening 123 from the side of the opening 123 closer to the base 200 along the extension direction of the first slide groove 121. After the first limiter 410 passes the position of the second limiter 420, the first arm 311 can be translated relative to the bracket 120 along the rotation axis of the first swing arm 310 so that the first arm 311 extends into the first slide groove 121, completing the installation of the first arm 311. At the same time, since the first arm body 311 and the second arm body 312 are spaced apart from each other in the aforementioned rotation axis direction, even after the first arm body 311 has been installed in the first slide groove 121, the first limiting portion 410 on the second arm body 312 and the second limiting portion 420 on the other side of the opening 123 can be spaced apart from each other, and the second arm body 312 can also extend from the opening 123 into the opening 123 along the aforementioned sliding direction, ensuring that the second limiting portion 420 will not interfere with the first limiting portion 410. Accordingly, after the first limiting portion 410 on the second arm body 312 passes over the other second limiting portion 420 at the opening 123, the second arm body 312 can also be translated relative to the bracket 120 along the aforementioned rotation axis and installed in the first slide groove 121.

[0042] In order to further reduce the difficulty of assembly between the first arm body 311 and the bracket 120, optionally, a side of the first arm body 311 facing away from the screen support side of the shell 110 can also be recessed to provide an avoidance groove 313, and the avoidance groove 313 is provided with a first limiting portion 410 at the end away from the base 200. At the same time, along the rotation axis of the first swing arm 310, the avoidance groove 313 provided on the first arm body 311 extends to the side of the first arm body 311 facing away from the second arm body 312, and at least a portion of the second limiting portion 420 can be located in the avoidance groove 313.

[0043] When the above-mentioned technical solution is adopted, when it is necessary to assemble the first arm body 311 and the bracket 120, in the process of the first arm body 311 extending into the opening 123 relative to the bracket 120 along the aforementioned sliding direction, a lateral force can be applied to the first arm body 311 along the rotation axis, and the first arm body 311 can be installed in the first slide groove 121. In this case, after the first limiting portion 410 on the first arm body 311 passes over the second limiting portion 420, it can be directly installed in the first slide groove 121 under the action of the aforementioned lateral force, which can greatly reduce the difficulty of assembly between the first arm body 311 and the bracket 120.

[0044] Of course, the dimensions of the avoidance groove 313 in the aforementioned sliding direction can also be designed so that in the sliding direction, the second limiter 420 can only slide between the opposite ends of the avoidance groove 313, thereby providing a stop for the electronic device during the switching process between the folded and unfolded states, further improving the reliability of the electronic device. In addition, the second arm 312 can also be provided with a groove structure similar to the avoidance groove 313, and the groove structure can be extended along the rotation axis to the side of the second arm 312 facing away from the first arm 311, thereby reducing the difficulty of assembling the second arm 312 and the bracket 120.

[0045] In order to further ensure the reliability of the limiting cooperation between the first limiting portion 410 and the second limiting portion 420, as shown in FIG. Figure 6 and Figure 7 As shown, in the rotational direction of the first swing arm 310, the overlap dimension A between the first limiting portion 410 and the second limiting portion 420 can be approximately 0.5 mm. In the relative sliding direction between the first swing arm 310 and the bracket 120, the dimension B of the first limiting portion 410 can be approximately 0.4 mm, and the dimension C of the second limiting portion 420 can be approximately 0.4 mm. In addition, due to processing accuracy and based on current processing conditions, it may not be possible to ensure that the first limiting portion 410 and the second limiting portion 420 exactly abut and fit when the electronic device switches to the folded state. Furthermore, to prevent the abutting and fitting relationship between the first limiting portion 410 and the second limiting portion 420 from interfering with the normal folding process of the electronic device, a gap can be provided between the first limiting portion 410 and the second limiting portion 420 in the aforementioned sliding direction when the electronic device is in the folded state. The dimension D of the gap can be approximately 0.1 mm. At the same time, in order to further improve the structural reliability of the first limiting portion 410 and the second limiting portion 420, the size E of each of the first limiting portion 410 and the second limiting portion 420 can be made approximately 0.3 mm in a direction perpendicular to both the aforementioned rotation axis and the sliding direction, or in the thickness direction of the first swing arm 310.

[0046] Based on the above embodiment, in order to further improve the stability of the relative fixed relationship between the base 200 and the housing 110 when the electronic device is in the folded state, optionally, as Figure 3 and 8 As shown, and combined Figure 9 and Figure 10 In the embodiment of the present application, a third limiting portion 430 may be further provided on the side of the first swing arm 310 that is away from the screen supporting side of the shell 110. At the same time, in the embodiment of the present application, a fourth limiting portion 440 may be further provided on the side of the shell 110 that faces the bracket 120, and the fourth limiting portion 440 may be provided to protrude from the shell 110 in the thickness direction of the shell 110.

[0047] Of course, in the process of designing electronic devices, the relative positions of the third limiting portion 430 and the fourth limiting portion 440 need to have a corresponding relationship, so that when the electronic device is in the unfolded state, the third limiting portion 430 and the fourth limiting portion 440 can be spaced apart, and when the electronic device is in the folded state, the third limiting portion 430 is in contact with the fourth limiting portion 440, thereby limiting the movement of the first swing arm 310 relative to the shell 110 toward the direction close to the base 200 in the sliding direction of the first swing arm 310 and the bracket 120.

[0048] As described above, during the transition of the electronic device between the unfolded and folded states, the first swing arm 310 and the bracket 120 are able to slide relative to each other, and the bracket 120 is fixedly connected to the housing 110. Therefore, the first swing arm 310 and the housing 110 are also able to move relative to each other in the aforementioned sliding direction. Based on this, more specifically, in the embodiment of the present application, the relative positional relationship between the third limiting portion 430 and the fourth limiting portion 440 can be determined based on the relative sliding range between the first swing arm 310 and the housing 110, so that when the electronic device is in the unfolded state, the third limiting portion 430 and the fourth limiting portion 440 are separated from each other by a predetermined distance along the aforementioned sliding direction.

[0049] More specifically, the third limiting portion 430 is also located on the back of the first swing arm 310. To this end, the first swing arm 310, the first limiting portion 410, and the third limiting portion 430 can be formed in an integral manner to reduce the difficulty of processing and connecting the aforementioned components. Of course, in other embodiments of the present application, if there is a corresponding need, the first swing arm 310, the first limiting portion 410, and the third limiting portion 430 can also be formed separately in a separate molding manner. Thereafter, the first limiting portion 410 and the third limiting portion 430 are fixedly connected to the corresponding positions on the back of the first swing arm 310 by welding or other means.

[0050] In addition, in the above embodiment, the first swing arm 310 may include a first arm body 311 and a second arm body 312. Based on this, in a specific embodiment of the present application, the first arm body 311 or the second arm body 312 may be provided with the third limiting portion 430. In another embodiment of the present application, both the first arm body 311 and the second arm body 312 may be provided with the third limiting portion 430. Correspondingly, two fourth limiting portions 440 may be provided on the side of the housing 110 facing the bracket 120, and the specific positions of the two fourth limiting portions 440 correspond to the relative positions of the two third limiting portions 430. Therefore, when the electronic device is in the folded state, the third limiting portions 430 of the first arm body 311 and the second arm body 312 can be mutually limited by the corresponding fourth limiting portions 440.

[0051] As described above, a second swing arm 320 is further provided between the base 200 and the brackets 120 on opposite sides thereof. More specifically, the second swing arm 320 may include a first mating portion 321, a second mating portion 322, and a connecting portion 323. The first mating portion 321 is rotationally connected to the bracket 120, and the second mating portion 322 is rotationally connected to the base 200. The first mating portion 321 is fixedly connected to the second mating portion 322 via the connecting portion 323. To further enhance the stability of the relative fixed relationship between the base 200 and the housing 110 (and the bracket 120) in the electronic device when in the folded state, based on the above-described structure of the second swing arm 320, a fifth limiting portion 450 may be further provided on the side of the housing 110 facing the bracket 120, with the fifth limiting portion 450 being arranged to protrude from the housing 110.

[0052] Among them, the fifth limiting portion 450 is used to cooperate with the connecting portion 323 of the second swing arm 320. For this reason, in the process of designing the fifth limiting portion 450, it is necessary to determine the setting position of the fifth limiting portion 450 on the shell 110 accordingly based on the relative position change between the second swing arm 320 and the shell 110 when the electronic device switches between the unfolded state and the folded state, so that when the electronic device is in the unfolded state, the connecting portion 323 and the fifth limiting portion 450 are spaced apart; at the same time, when the electronic device is in the folded state, the connecting portion 323 is abutted against the fifth limiting portion 450, thereby limiting the second swing arm 320 from moving relative to the shell 110 toward the direction close to the base 200 in the sliding direction between the first swing arm 310 and the bracket 120. In this case, the stability of the relative fixed state between the base 200 and the shell 110 can be further improved. At the same time, since the second matching portion 322 of the second swing arm 320 can be a bearing-like arc structure, it can also prevent the second matching portion 322 from being misaligned with the rotating groove on the base 200, causing jamming between the second swing arm 320 and the base 200, thereby affecting the normal unfolding and folding of the electronic device.

[0053] As described above, the second mating portion 322 of the second swing arm 320 can utilize a bearing-like arcuate structure to form a rotational connection with the base 200, thereby increasing the relative rotational angle between the second swing arm 320 and the base 200. This reduces the deformation of the display screen 3 sandwiched between the second swing arms 320 on opposite sides of the base 200 when the electronic device is folded. The first mating portion 321 of the second swing arm 320 can be rotationally mated with the bracket 120 via a shaft-hole connection structure.

[0054] In another embodiment of the present application, the bracket 120 can also be provided with a second slide groove 122, and the first matching portion 321 can be rotatably and slidably installed in the second slide groove 122 to reduce the rotation angle of the second swing arm 320 relative to the base 200, thereby making the size of the overlapping portion between the second matching portion 322 and the base 200 relatively larger, thereby improving the connection stability between the second swing arm 320 and the base 200.

[0055] Specifically, in the embodiment of the present application, the bracket 120 is provided with a second slide groove 122. The extension direction of the second slide groove 122 has a first component and a second component, the first component being parallel to the sliding direction, and the second component being parallel to the thickness direction of the bracket 120. The first mating portion 321 is rotatably and slidably mounted on the second slide groove 122. Intuitively speaking, the extension direction of the second slide groove 122 is inclined both relative to the aforementioned sliding direction and relative to the thickness direction of the bracket 120. Of course, the extension direction of the second slide groove 122 is generally perpendicular to the rotation axis of the first swing arm 310 (and the second swing arm 320).

[0056] Based on the above structure, since the first engaging portion 321 of the second swing arm 320 can move within the second slide groove 122, when the electronic device is in the unfolded state, the spacing between the first engaging portion 321 and the housing 110 in the thickness direction of the housing 110 is a first spacing; when the electronic device is in the folded state, the spacing between the first engaging portion 321 and the housing 110 in the thickness direction of the housing 110 is a second spacing, which is smaller than the first spacing. Intuitively, during the process of switching the electronic device from the unfolded state to the folded state, the first engaging portion 321 moves along the second slide groove 122, gradually moving away from the display screen 3 (or gradually approaching the corresponding housing 110).

[0057] When the above technical solution is adopted, in order to further improve the reliability of the relative fixed relationship between the second swing arm 320 and the base 200 when the electronic device is in the folded state, a sixth limiting portion 460 can be provided on the side of the shell 110 facing the bracket 120. The sixth limiting portion 460 protrudes from the shell 110 and faces the second slide groove 122, so that the sixth limiting portion 460 provides a stopping effect for the first matching portion 321 installed in the second slide groove 122, thereby preventing the base 200 from being subjected to the internal stress of the display screen 3 when the electronic device is in the folded state, driving the second swing arm 320 to continue to rotate relative to the base 200 toward the direction close to the shell 110, thereby ensuring that the electronic device is stably maintained in the folded state.

[0058] Accordingly, if Figure 9As shown, when the electronic device is in the unfolded state, the first matching portion 321 and the sixth limiting portion 460 are spaced apart in the extension direction of the second slide groove 122; when the electronic device is in the folded state, the first matching portion 321 abuts against the sixth limiting portion 460 to limit the first matching portion 321 from moving relative to the bracket 120 toward the shell 110 in the extension direction of the second slide groove 122.
