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] Folding screen mobile phones are becoming more and more popular with users due to their large display area and strong portability. In a folding screen mobile phone, two adjacent shells are connected by a rotating assembly including multiple parts to form a hinge mechanism. In order to ensure that the hinge mechanism has the ability to fold and unfold, a rotating connection relationship is formed between some components in the hinge mechanism.

[0003] Usually, the rotational connection relationship is formed by a shaft-hole combination structure, and in order to ensure that the rotation action is relatively smooth, there is a fitting gap between the shaft holes. In this case, when the electronic device is in the unfolded state, its two adjacent shells still have the ability to approach and move away from each other, which makes the display screen fixedly connected to the shell easy to be squeezed or stretched, which makes the display screen prone to arching or over-stretching, which has a significant adverse effect on the display effect and service life of the display screen. 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 an unfolded state, two adjacent shells still have the ability to move closer to or farther from each other, which causes the display screen to easily arch and over-stretch, which has a significant adverse effect on the display effect and service life of the display screen.

[0005] The embodiment of the present application discloses an electronic device, which includes a base, a first swing arm, a housing, an elastic extrusion member, a first extrusion member and a second extrusion member, wherein: The housing is provided with a plurality of first slide grooves, and a plurality of first swing arms are provided on one side of the base, the first end of each of the first swing arms is rotatably connected to the base, and the second end of each of the first swing arms is slidably matched with the plurality of first slide grooves in a one-to-one correspondence; Among the two adjacent first swing arms, the second end of one is provided with a first inclined surface, and the other is provided with a third inclined surface, the first inclined surface and the third inclined surface are both arranged obliquely relative to the extension direction of the first slide slot, and the first inclined surface and the third inclined surface are both arranged obliquely relative to the rotation axis of the first swing arm, and the first inclined surface and the third inclined surface are in a flared structure; The first pushing member and the second pushing member are both installed on the shell, and the first pushing member is provided with a second inclined surface, and the second pushing member is provided with a fourth inclined surface, the second inclined surface is slidably matched with the first inclined surface, and the fourth inclined surface is slidably matched with the third inclined surface, and the elastic extrusion member is elastically abutted between the first pushing member and the second pushing member.

[0006] The embodiment of the present application discloses an electronic device, wherein a housing is provided with a plurality of first slide grooves, a plurality of first swing arms are rotatably provided on one side of a base, and the plurality of first swing arms are slidably matched with the plurality of first slide grooves in a one-to-one correspondence, so that the housing and the base form an assembly relationship. At the same time, of the two adjacent first swing arms located on the same side of the base, a first inclined surface is provided at the second end of one, and a third inclined surface is provided at the other. Both the first inclined surface and the third inclined surface are inclined relative to the extension direction of the first slide groove, and are inclined relative to the rotation axis of the first swing arm. The first inclined surface and the third inclined surface are also generally in a flared structure, so as to slide and match with the second inclined surface and the fourth inclined surface on the first extrusion member and the second extrusion member, respectively.

[0007] In addition, an elastic extrusion member is elastically extruded between the first pushing member and the second pushing member clamped between the two adjacent first swing arms, and the elastic extrusion member can drive the first pushing member and the second pushing member to move in directions away from each other along the rotation axis of the first swing arm. Affected by the structural design of the first inclined plane and the third inclined plane, in the process of the first pushing member and the second pushing member moving away from each other, both of them also move in the extension direction of the first slide groove away from the base, and the first pushing member and the second pushing member are both installed on the shell, so that the shell also has a tendency to move in the direction away from the base along the aforementioned extension direction. Therefore, when the user applies a driving force to the shell, the elastic extrusion member can overcome the component force of the aforementioned driving force that makes the shell move in the direction close to the base, thereby preventing the shell and the base from getting close to each other and squeezing the display screen, thereby ensuring a relatively long service life of the display screen.

DETAILED DESCRIPTION

[0010] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments 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 without creative work are within the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0012] The present application discloses an electronic device, which is specifically a foldable electronic device, that is, the electronic device includes a hinge mechanism so that the electronic device has a folded state and an unfolded state, and can switch between the folded state and the unfolded state. Figure 1-Figure 12 As shown, the electronic device includes a base 100, a first swing arm 300, a shell 400, an elastic extrusion member 510, a first pushing member 520 and a second pushing member 530. Of course, the electronic device usually also includes other mechanisms and components such as a display screen, which will not be introduced one by one in this article.

[0013] In the electronic device disclosed in the embodiment of the present application, the first swing arm 300 serves as a connection structure between the base 100 and the housing 400, and in order to improve the connection stability between the base 100 and the housing 400, a plurality of first swing arms 300 are provided on one side of the base 100, and correspondingly, the housing 400 is provided with a plurality of first slide grooves 431, the first end of each first swing arm 300 is rotatably connected to the base 100, and the second end of each first swing arm 300 is slidably matched with the plurality of first slide grooves 431 in a one-to-one correspondence, so that the plurality of first swing arms 300 are all installed between the base 100 and the housing 400. More optionally, the housing 400 includes a shell body 410 and a bracket 430 that are fixedly connected, and the first slide groove 431 is provided on the bracket 430, and in addition, the second slide groove 432 described below is also provided on the bracket 430.

[0014] In detail, the first swing arm 300 and the base 100 can form a rotational fit relationship through a rotating shaft or other device, which makes the connection stability between the two relatively high. For the first slide groove 431 on the housing 400, its extension direction is perpendicular to the axial direction of the aforementioned rotating shaft. In layman's terms, the first slide groove 431 extends straight from one side of the housing 400 close to the base 100 to the other side of the housing 400. In addition, in the electronic device disclosed in the embodiment of the present application, in order to further improve the reliability of the rotational connection relationship between the base 100 and the shell 400, the electronic device can generally further include a second swing arm 200. The second swing arm 200 is also connected between the base 100 and the shell 400, but is different from the first swing arm 300. During the assembly of the second swing arm 200, the base 100 and the shell 400 both form a rotational cooperation relationship with the first swing arm 300. In this case, the rotation centers of the first swing arm 300 and the second swing arm 200 can be misaligned with each other, so that the rotation angle of the second swing arm 200 relative to the base 100 can be greater than the rotation angle of the first swing arm 300 relative to the base 100, so that the first swing arms 300 on the opposite sides of the base 100 can form a flared structure, and the aforementioned flaring is toward the side where the base 100 is located, which makes the accommodation space corresponding to the middle area of ​​the base 100 in the display screen of the electronic device relatively larger, so as to prevent the middle area of ​​the display screen from being excessively squeezed and damaged during the folding process of the electronic device.

[0015] As described above, the first swing arm 300 and the base 100 can form a rotational connection relationship through a structure such as a rotating shaft. Furthermore, in order to ensure that the first swing arm 300 and the base 100 can rotate smoothly and stably relative to each other, during the processing of the electronic device, it is usually necessary to provide a gap between the rotating shaft and the shaft hole on the first swing arm 300. In this case, when the user needs to switch the electronic device from an unfolded state to a folded state, it is necessary to apply a force to the shells 400 on opposite sides of the base 100 in the electronic device. The aforementioned force has a tendency to cause the shells 400 on opposite sides of the base 100 to move toward each other. As described above, since there is a gap between the rotating shaft and the shaft hole of the first swing arm 300, driven by the aforementioned force, the shells 400 on opposite sides of the base 100 will be squeezed inward, thereby causing the display screens installed on opposite sides of the base 100 to be arched, thereby adversely affecting the display effect and service life of the display screens.

[0016] Based on the above situation, in the electronic device disclosed in the embodiment of the present application, among the two adjacent first swing arms 300, the second end of one is provided with a first inclined surface 301, and the other is provided with a third inclined surface 302, and the first inclined surface 301 and the third inclined surface 302 are both inclined relative to the extension direction of the first slide groove 431, and the first inclined surface 301 and the third inclined surface 302 are also inclined relative to the rotation axis of the first swing arm 300; in other words, in the embodiment of the present application, the first inclined surface 301 and the third inclined surface 302 both have a first component parallel to the extension direction of the first slide groove 431, and the first inclined surface 301 and the third inclined surface 302 both have a second component parallel to the rotation axis of the first swing arm 300. At the same time, the first inclined surface 301 and the second inclined surface 521 are in a flared structure, and the flare of the aforementioned flared structure is set away from the direction of the base 100, that is, in the embodiment of the present application, the inclination directions of the first inclined surface 301 and the second inclined surface 521 are opposite. Intuitively speaking, with the two first swing arms 300 distributed in the left and right directions, the overall inclination direction of the first inclined surface 301 on the left first swing arm 300 can be from the upper left to the lower right, and correspondingly, the overall inclination direction of the second inclined surface 521 on the right first swing arm 300 can be from the upper right to the lower left.

[0017] In this case, since the two first swing arms 300 are distributed along the axial direction of the rotating shaft (i.e., the left and right direction mentioned above), the first pushing members 520 and the second pushing members 530 corresponding to the two first swing arms 300 respectively move in directions away from each other, so that the first pushing members 520 and the second pushing members 530 can move together in the direction away from the base 100, thereby enabling the first pushing members 520 and the second pushing members 530 to apply a driving force to the shell 400 to move the shell 400 away from the base 100.

[0018] In detail, in the embodiment of the present application, the first pushing member 520 and the second pushing member 530 are both installed on the shell 400. Specifically, a clamping and limiting method can be adopted to make the first pushing member 520 and the second pushing member 530 form an assembly relationship with the shell 400, so that the first pushing member 520 and the second pushing member 530 are relatively fixed to the shell 400 in the extension direction of the first slide groove 431. At the same time, by providing the first pushing member 520 with the second inclined surface 521 and the second pushing member 530 with the fourth inclined surface 531, during the assembly process of the first pushing member 520 and the second pushing member 530, the second inclined surface 521 is slidably matched with the first inclined surface 301, and the fourth inclined surface 531 is slidably matched with the third inclined surface 302; and by making the elastic extrusion member 510 elastically abut between the first pushing member 520 and the second pushing member 530, the elastic extrusion member 510 can provide an elastic extrusion force, so that the first pushing member 520 and the second pushing member 530 have a movement tendency to move away from each other, and then, the first pushing member 520 and the second pushing member 530 are in a state of being moved away from each other. When the first and second pushing members 520 and 530 have the ability to move away from each other, the first pushing member 520 and the second pushing member 530 move away from each other along the first inclined surface 301 and the third inclined surface 302 respectively, and during the process of the two moving away from each other, the first pushing member 520 and the second pushing member 530 can correspondingly drive the shell 400 to move in the direction away from the base 100, and then when the user applies a squeezing force to the shell 400 on the opposite sides of the base 100, the elastic squeezing member 510 can generate a driving force that reacts with the aforementioned squeezing force, thereby preventing the shell 400 on the opposite sides of the base 100 from being squeezed inwardly, thereby ensuring that the display screen will not produce a reverse arch phenomenon, thereby improving the display effect and service life of the display screen.

[0019] As described above, the electronic device has housings 400 on both sides of the base 100, and both housings 400 are connected to the base 100 through corresponding first swing arms 300. In a specific embodiment of the present application, in order to reduce the difficulty of assembling the electronic device, multiple first swing arms 300 can be provided only on one side of the base 100, and the first pushing member 520, the second pushing member 530 and the elastic pressing member 510 are provided between two adjacent first swing arms 300 on the side of the base 100. In order to maximally prevent the display screen from being squeezed and causing the reverse arch phenomenon, in another embodiment of the present application, multiple first swing arms 300 are provided on both sides of the base 100, and the first pushing member 520, the second pushing member 530 and the elastic pressing member 510 are provided between adjacent first swing arms 300 on either side of the base 100.

[0020] The embodiment of the present application discloses an electronic device, wherein a housing 400 is provided with a plurality of first slide grooves 431, a plurality of first swing arms 300 are rotatably provided on one side of a base 100, and the plurality of first swing arms 300 are slidably matched with the plurality of first slide grooves 431 in a one-to-one correspondence, so that the housing 400 and the base 100 form an assembly relationship. At the same time, of the two adjacent first swing arms 300 located on the same side of the base 100, a first inclined surface 301 is provided at the second end of one, and a third inclined surface 302 is provided at the other. The first inclined surface 301 and the third inclined surface 302 are both inclined relative to the extension direction of the first slide groove 431, and are both inclined relative to the rotation axis of the first swing arm 300. The first inclined surface 301 and the third inclined surface 302 are also generally flared structures, so as to slide with the second inclined surface 521 and the fourth inclined surface 531 on the first extrusion member 520 and the second extrusion member 530, respectively.

[0021] In addition, an elastic extrusion member 510 is elastically extruded and arranged between the first extrusion member 520 and the second extrusion member 530 sandwiched between the two adjacent first swing arms 300. The elastic extrusion member 510 can drive the first extrusion member 520 and the second extrusion member 530 to move away from each other along the rotation axis of the first swing arm 300. Influenced by the structural design of the first inclined surface 301 and the third inclined surface 302, during the process of the first extrusion member 520 and the second extrusion member 530 moving away from each other, both of them also move along the extension direction of the first slide groove 431. The shell 400 moves in the direction away from the base 100, and the first pushing member 520 and the second pushing member 530 are both installed on the shell 400, so that the shell 400 also has a tendency to move in the direction away from the base 100 along the aforementioned extension direction. When the user applies a driving force to the shell 400, the elastic pushing member 510 can overcome the component of the driving force that makes the shell 400 move in the direction close to the base 100, thereby preventing the shell 400 and the base 100 from getting close to each other and squeezing the display screen, thereby ensuring that the service life of the display screen is relatively long.

[0022] As described above, the first pushing member 520 and the second pushing member 530 can be assembled with the housing 400 by means of clamping and limiting, so that the first pushing member 520 and the second pushing member 530 can form a relatively fixed relationship with the housing 400 in the extension direction of the first slide groove 431. In order to further improve the installation stability of the first pushing member 520 and the second pushing member 530, in a specific embodiment of the present application, the housing 400 is provided with a receiving groove 413, and the first pushing member 520, the elastic extrusion member 510 and the second pushing member 530 are all installed in the receiving groove 413, so that the receiving groove 413 provides a certain limiting effect for the first pushing member 520 and the second pushing member 530.

[0023] More optionally, the side surfaces of the first pushing member 520 and the second pushing member 530 facing away from the base 100 can cooperate with the bottom of the accommodating groove 413, so that when the first pushing member 520 and the second pushing member 530 move away from each other and move together away from the base 100, the first pushing member 520 and the second pushing member 530 can cooperate with the bottom of the accommodating groove 413 to drive the shell 400 to move in a direction away from the base 100.

[0024] In the embodiment of the present application, a receiving groove 413 is provided on the shell 400, which has a groove bottom, and correspondingly, the receiving groove 413 also has a groove wall, that is, a side wall, wherein the two groove walls of the receiving groove 413 opposite to each other along the rotation axis of the first swing arm 300 are respectively the first groove side wall and the second groove side wall. As mentioned above, the receiving groove 413 is used to accommodate the first pushing member 520 and the second pushing member 530, and the first pushing member 520 and the second pushing member 530 have the ability to move away from each other along the aforementioned rotation axis. Furthermore, in order to prevent the first groove side wall and the second groove side wall of the receiving groove 413 from hindering the process of the first pushing member 520 and the second pushing member 530 moving away from each other, in the embodiment of the present application, the distance between the first groove side wall and the second groove side wall can be made larger than the maximum movement range between the first pushing member 520 and the second pushing member 530.

[0025] In other words, in the embodiment of the present application, when the end face of one end of the first pushing member 520 away from the second pushing member 530 is limited to the first groove side wall of the accommodating groove 413, and the end face of the second pushing member 530 away from the first pushing member 520 is limited to the second groove side wall of the accommodating groove 413, the first inclined surface 301 moves to the end of the second inclined surface 521 away from the base 100, but a portion of the first inclined surface 301 is still matched with the second inclined surface 521. Correspondingly, the third inclined surface 302 moves to the end of the fourth inclined surface 531 away from the base 100, and a portion of the third inclined surface 302 is still matched with the fourth inclined surface 531. In this case, the first pushing member 520 and the second pushing member 530 can still move along the second inclined surface 521 and the fourth inclined surface 531 respectively and approach each other when subjected to the force of mutual extrusion.

[0026] As described above, the elastic extrusion member 510 elastically abuts between the first extrusion member 520 and the second extrusion member 530. Optionally, the elastic extrusion member 510 can be a compression spring. In order to prevent the shell 400 from moving toward the direction close to the base 100 due to external force as much as possible, in the embodiment of the present application, after the first extrusion member 520 and the second extrusion member 530 are respectively limited by the first groove side wall and the second groove side wall, the elastic extrusion member 510 can still be in a compressed state.

[0027] Furthermore, in order to prevent the elastic extrusion member 510 from bending and deforming when it is in a compressed state, in a specific embodiment of the present application, the shell 400 can include a shell body 410 and a surrounding portion 420, wherein the shell body 410 is provided with a receiving groove 413, the surrounding portion 420 is fixed to the shell body 410, and the surrounding portion 420 is arranged toward the notch of the receiving groove 413, and by clamping at least a portion of the elastic extrusion member 510 between the surrounding portion 420 and the bottom of the receiving groove 413, the bottom of the receiving groove 413 and the surrounding portion 420 can provide a certain limiting effect for the elastic extrusion member 510, thereby preventing the elastic extrusion member 510 from bending and deforming during operation and losing the ability to drive the first extrusion member 520 and the second extrusion member 530 away from each other.

[0028] Optionally, the enclosure 420 can be integrally formed with the shell body 410, or the enclosure 420 can be fixed at the notch of the receiving groove 413 by welding or bonding. In addition, in the rotation axis direction of the first swing arm 300, it is necessary to make the size of the enclosure 420 smaller than the size of the receiving groove 413, and make the size of the first pushing member 520 and the second pushing member 530 in the aforementioned rotation axis direction larger than the maximum distance between the bottom of the receiving groove 413 and the enclosure 420, so that a part of each of the first pushing member 520 and the second pushing member 530 can pass over the enclosure 420 and be located on the side of the enclosure 420 away from the receiving groove 413, thereby ensuring that the first pushing member 520 and the second pushing member 530 can still cooperate with the corresponding first swing arm 300.

[0029] Of course, in order to ensure that the first pushing member 520 and the second pushing member 530 can still move along the second inclined surface 521 and the fourth inclined surface 531 respectively to approach and move away from each other, in the embodiment of the present application, it is also necessary to design the distance between the enclosure 420 and the bottom of the receiving groove 413, so that when the first pushing member 520 and the second pushing member 530 are mutually limited with the enclosure 420, the first inclined surface 301 slides to the end of the second inclined surface 521 close to the base 100 and still cooperates with the second inclined surface 521, and accordingly, the third inclined surface 302 moves to the end of the fourth inclined surface 531 close to the base 100, and a part of the third inclined surface 302 still cooperates with the fourth inclined surface 531. In this case, when the first pushing member 520 and the second pushing member 530 are driven by the elastic extrusion member 510, the two can still move along the second inclined surface 521 and the fourth inclined surface 531 respectively and move away from each other.

[0030] Optionally, the first pushing member 520 can be provided with a first limiting end face 522 on the side facing the enclosure portion 420, and the second pushing member 530 can be provided with a second limiting end face 532 on the side facing the enclosure portion 420. In the process of the first pushing member 520 and the second pushing member 530 continuing to approach each other, one of the two end faces of the enclosure portion 420 opposite to each other along the aforementioned rotation axis can be limitedly matched with the first limiting end face 522, and the other can be limitedly matched with the second limiting end face 532, so that the enclosure portion 420 and the accommodating groove 413 can respectively limit the minimum spacing and the maximum spacing between the first pushing member 520 and the second pushing member 530.

[0031] As described above, the enclosure portion 420 is provided at the notch of the receiving groove 413 to improve the assembly stability of the elastic extrusion member 510, the first extrusion member 520 and the second extrusion member 530. In this case, in order to ensure that the first extrusion member 520 and the second extrusion member 530 can be normally installed between the enclosure portion 420 and the receiving groove 413, the distance between the enclosure portion 420 and the receiving groove 413 can be made relatively large, or the enclosure portion 420 and the receiving groove 413 can be detachably fixedly connected, so that after the first extrusion member 520 and the second extrusion member 530 are installed in the receiving groove 413, the enclosure portion 420 can be installed at the notch of the receiving groove 413.

[0032] In another embodiment of the present application, the shell body 410 can include a main body portion 411 and a pressure cover portion 412, wherein the main body portion 411 and the pressure cover portion 412 are formed separately, that is, during the processing of the shell body 410, the main body portion 411 and the pressure cover portion 412 are processed and formed separately, and then the first pushing member 520 and the second pushing member 530, and the elastic extrusion member 510 can be installed in the main body portion 411 through the top opening of the main body portion 411. In this case, the main body portion 411 and the pressure cover portion 412 are fixedly connected by bonding or welding, and form a receiving groove 413. In this case, the difficulty of installing the first pushing member 520 and the second pushing member 530 can also be reduced, and the stability of the relative fixed relationship between the enclosing portion 420 and the bottom of the accommodating groove 413 can be ensured to be relatively higher, and the distance between the enclosing portion 420 and the bottom of the accommodating groove 413 can be made relatively small, so as to improve the matching reliability between the first pushing member 520 and the second pushing member 530 and the corresponding first swing arm 300.

[0033] As described above, the enclosure 420 can provide a certain limiting effect for the elastic extrusion member 510. In order to further improve the stability of the elastic extrusion member 510 and prevent it from bending and deforming during compression, in another embodiment of the present application, the first extrusion member 520 can include an extrusion body 523 and a guide column 524, wherein the first inclined surface 301 is provided on the extrusion body 523, and the guide column 524 is inserted into the elastic extrusion member 510. In this case, the guide column 524 can provide a more reliable limiting effect for the elastic extrusion member 510, thereby further improving the compression linearity of the elastic extrusion member 510.

[0034] Similarly, the second pushing member 530 may also include a pushing body 523 and a guide post 524, and the pushing body 523 of the second pushing member 530 may be provided with a third inclined surface 302, and the guide post 524 of the second pushing member 530 is plugged into the other end of the elastic pushing member 510, thereby providing a more reliable limiting effect for the elastic pushing member. In addition, the pushing bodies 523 of the first pushing member 520 and the second pushing member 530 may each be provided with a weight-reducing hole 525 to reduce the weight of the first pushing member 520 and the second pushing member 530, thereby facilitating the movement of the two and making the electronic device thinner and lighter.

[0035] Of course, the sizes of the guide posts 524 of the first extrusion member 520 and the second extrusion member 530 can generally be such that the sum of their sizes is smaller than the size of the elastic extrusion member 510 when it is in the maximum compression state, so as to prevent the existence of the guide posts 524 from interfering with the compression process of the elastic extrusion member 510. Alternatively, the guide posts 524 of the first extrusion member 520 and the second extrusion member 530 can be arranged in a staggered manner, which can also prevent the guide posts 524 from interfering with the compression process of the elastic extrusion member 510.

[0036] In order to further improve the matching stability between the first pushing member 520 and the second pushing member 530 and the corresponding first swing arm 300, and to reduce the design difficulty of the first swing arm 300 and other components, in a specific embodiment of the present application, the first inclined surface 301 and the third inclined surface 302 can be made parallel to each other in the thickness direction of the base 100, and at the same time, the second inclined surface 521 is arranged in abutment with the first inclined surface 301, and the fourth inclined surface 531 is arranged in abutment with the third inclined surface 302. In this case, when the first pushing member 520 and the second pushing member 530 move relative to the base 100 along the rotation axis of the first swing arm 300, only a synchronous movement relative to the base 100 along the extension direction of the first slide groove 431 will occur, and no movement relative to the base 100 in other directions will occur, which, on the one hand, makes the size of the first pushing member 520 and the second pushing member 530 in the thickness direction of the base 100 relatively smaller, and on the other hand, can also reduce the size of the structure such as the above-mentioned receiving groove 413, thereby further improving the lightness and thinness of the electronic device. The thickness direction of the base 100 is perpendicular to the rotation axis of the first swing arm 300 and the extension direction of the first sliding groove 431 .

[0037] In addition, in order to improve the utilization efficiency of the elastic force of the elastic extrusion member 510, in a specific embodiment of the present application, the elastic direction of the elastic extrusion member 510 can be parallel to the rotation axis of the first swing arm 300. In this case, it can also prevent the elastic force of the elastic extrusion member 510 from generating a component force that is not parallel to the aforementioned rotation axis, thereby preventing the first extrusion member 520 and the second extrusion member 530 from having an adverse effect on the matching stability between the corresponding first swing arm 300.

[0038] As described above, in the hinge mechanism, a second swing arm 200 may be further provided, so as to make the assembly relationship between the base 100 and the housing 400 more stable. In the above embodiment, one end of each second swing arm 200 may be rotatably connected to the base 100, and the other end of the second swing arm may be rotatably connected to the housing 400, so that the second swing arm may be used to make the housing 400 rotate relative to the base 100 more reliably.

[0039] In another embodiment of the present application, one end of the second swing arm 200 can be rotatably connected to the base 100, so that the other end of the second swing arm 200 can be rotatably connected to the shell 400 and can also have the ability to slide relative to the shell 400.

[0040] More optionally, in an embodiment of the present application, a bearing-type connection structure can be used to form a rotational connection relationship between the second swing arm 200 and the base 100. In this case, the rotation axis between the second swing arm 200 and the base 100 can be located outside the base 100. Furthermore, after the second swing arms 200 on opposite sides of the base 100 rotate the same angle relative to the base 100, compared to the method of using a rotating shaft connection, if the distance between the rotation axes of the two second swing arms 200 relative to the base 100 is the same, by adopting the rotational connection form disclosed in the above embodiment of the present application, the distance between the two second swing arms 200 is relatively larger, and the aforementioned distance is used to accommodate the display screen, thereby expanding the accommodating space of the display screen.

[0041] From another perspective, after the second swing arms 200 on opposite sides of the base 100 rotate the same angle relative to the base 100, compared to the method of adopting a hinge connection, when in a folded state, the spacing between the two second swing arms 200 for accommodating the display screen is the same. By adopting the rotation connection form disclosed in the above embodiment of the present application, the spacing between the rotation axes of the two second swing arms 200 relative to the base 100 can be reduced, thereby reducing the width dimension of the hinge mechanism in the electronic device, so that the installation space occupied by the hinge mechanism is relatively smaller.

[0042] At the same time, the second swing arm 200 can form an assembly relationship with the connection part of the housing 400, and the two have the ability to rotate and move relative to each other. In detail, the housing 400 is provided with a second slide groove 432, and the extension direction of the second slide groove 432 has a component parallel to the thickness direction of the housing 400. As above, the thickness direction of the base 100 is perpendicular to the rotation axis of the first swing arm 300 and the extension direction of the first slide groove 431. In addition, when the hinge mechanism is in the unfolded state, the thickness direction of the electronic device is parallel to the thickness direction of the base 100.

[0043] Correspondingly, the second swing arm 200 is installed in the second slide slot 432, and the second swing arm 200 can move relative to the housing 400 along the extension direction of the second slide slot 432. In the process of the second swing arm 200 moving relative to the second slide slot 432, the second swing arm 200 can also rotate relative to the second slide slot 432, so as to adapt to the relative rotation between the second swing arm 200 and the housing 400 during the switching of the hinge mechanism between the unfolded state and the folded state. Of course, in order to ensure that the second swing arm 200 has the ability to slide and rotate relative to the second slide slot 432, in the embodiment of the present application, the part of the second swing arm 200 installed in the second slide slot 432 can include a cylindrical structure, so that the outer surface of the second swing arm 200 that directly contacts the groove wall of the second slide slot 432 is a cylindrical side surface structure.

[0044] For example, the second slide groove 432 can be extended along the thickness direction of the housing 400. In this case, the movement path of the second swing arm 200 is designed, and the relative movement between the second swing arm 200 and the housing 400 can be coordinated with the relative movement between the housing 400 and the base 100. In more detail, when the electronic device is in the folded state, the second swing arm 200 is located in the second slide groove 432 at a position relatively far from the screen support side of the housing 400, and in the process of switching the electronic device from the folded state to the unfolded state, the second swing arm 200 is rotated and slid in the second slide groove 432, so that the second swing arm 200 moves toward the screen support side of the housing 400, that is, the side where the screen support side of the hinge mechanism is located, and then when the electronic device is switched to the unfolded state, the second swing arm 200 is located in the second slide groove 432 at a position relatively close to the screen support side of the housing 400.

[0045] Obviously, by forming the above-mentioned matching relationship between the second swing arm 200 and the shell 400, during the rotation of the shell 400 relative to the base 100, the shell 400 can drive the second swing arm 200 to rotate relative to the base 100, and at the same time, the second swing arm 200 and the shell 400 can also generate relative rotation. Moreover, by restricting the above-mentioned movement mode of the second swing arm 200, the relative rotation direction between the second swing arm 200 and the shell 400 is opposite to the relative rotation direction between the shell 400 and the base 100. Therefore, during the switching of the electronic device between the unfolded and folded states, the rotation angle of the second swing arm 200 relative to the base 100 is also smaller than the rotation angle of the shell 400 relative to the base 100. Therefore, the rotation angle of the second swing arm 200 relative to the base 100 is generally less than 90°.

[0046] When the above technical solution is adopted, when the electronic device is in a folded state, the size of the portion of the second swing arm 200 that is still located in the base 100 in the second swing arm 200 that forms a rotational connection relationship with the base 100 using a bearing structure is relatively larger, thereby improving the stability of the rotational connection relationship between the second swing arm 200 and the base 100; and, since the rotation angle of the second swing arm 200 relative to the base 100 is relatively small, the space formed by the second swing arms 200 located on opposite sides of the base 100 in the electronic device in the folded state can be relatively larger, and when the electronic device is in the folded state, the size of the gap between the second swing arm 200 and the display screen can be increased, thereby reducing the probability of the second swing arm 200 squeezing the display screen; at the same time, the thickness of the second swing arm 200 can be appropriately increased, thereby improving the overall structural reliability of the second swing arm 200, thereby improving the service life of the electronic device.

[0047] In the above embodiment, the second slide groove 432 can be extended along the thickness direction of the housing 400. In another embodiment of the present application, the second slide groove 432 can also have corresponding components in both the thickness direction of the housing 400 and the extension direction of the first slide groove 431, wherein, when the electronic device is in the unfolded state, the extension direction of the first slide groove 431 is parallel to the width direction of the housing 400. That is, the second slide groove 432 is inclined relative to the thickness direction of the housing 400 and the width direction of the housing 400.

[0048] Furthermore, as for the inclination of the second slide groove 432 relative to the thickness direction, optionally, as Fig.11 As shown, when the electronic device is in the unfolded state, the end of the second slide groove 432 away from the screen support side of the electronic device can be relatively closer to the base 100 of the electronic device. That is, when the electronic device is in the unfolded state, the distance between the end of the second slide groove 432 away from the screen support side of the electronic device and the base 100 is smaller than the distance between the end of the second slide groove 432 close to the screen support side of the electronic device and the base 100. In this case, it is possible to prevent the second slide groove 432 from having a component in the width direction of the housing 400, which may cause a negative effect on the relative rotation between the second swing arm 200 and the housing 400.

[0049] As described above, one end of the second swing arm 200 forms an assembly relationship with the shell 400 through the second slide groove 432. In order to ensure that the second swing arm 200 can form a relatively smooth and stable relative motion relationship with the second slide groove 432, it is also necessary to form an assembly gap between the second swing arm 200 and the second slide groove 432 in the width direction of the shell 400. In this case, during the folding of the electronic device, the shells 400 on the opposite sides of the base 100 will also have a tendency to be squeezed inwards due to the squeezing force. Based on this, in order to ensure that the electronic device has a stable state in the unfolded state, A relatively large outward stroke is provided to ensure that the flattening degree of the display screen is relatively high, to prevent the display screen from being arched, and at the same time, to ensure that the electronic device has a relatively small amount of rubbing and falling stability in the folded state. In the embodiment of the present application, the second slide groove 432 may include a first groove section 432a and a second groove section 432b that are interconnected, wherein the second groove section 432b is located on the side of the first groove section 432a that is away from the screen supporting side of the housing 400, and in the extension direction of the first slide groove 431, the size of the first groove section 432a is larger than the size of the second groove section 432b. At the same time, in the embodiment of the present application, when the electronic device is in the unfolded state, the second end of the second swing arm 200 is located in the first groove section 432a; and when the electronic device is in the folded state, the second end of the second swing arm 200 is located in the second groove section 432b.

[0050] Furthermore, the first groove section 432a can include a first groove surface 4321 and a second groove surface 4322 opposite to each other along the extension direction, and the second groove section 432b can include a third groove surface 4323 and a fourth groove surface 4324 opposite to each other along the extension direction, wherein the first groove surface 4321 is connected to the third groove surface 4323 and is coplanarly arranged, and the second groove surface 4322 is located on the side of the fourth groove surface 4324 close to the base 100. In this case, the processing difficulty of the first groove surface 4321 and the third groove surface 4323 is relatively small, and in the process of the hinge mechanism switching from the folded state to the unfolded state, the third groove surface 4323 and the first groove surface 4321 can provide a guiding effect for the second swing arm 200, so that the second swing arm 200 can move relatively smoothly in the second slide groove 432.

[0051] As described above, in the process of the electronic device switching from the unfolded state to the folded state, the shells 400 on the opposite sides of the base 100 will be subjected to an extrusion force, so that the shells 400 on the opposite sides of the base 100 will have a movement tendency and movement situation approaching each other. For this reason, in the aforementioned process, the second swing arm 200 may move from a position in contact with the first groove surface 4321 to a position close to the second groove surface 4322. At the same time, since the size of the first groove section 432a is greater than the size of the second groove section 432b in the extension direction of the first slide groove 431, in order to prevent the second swing arm 200 from getting stuck at the fourth groove surface 4324, in a specific embodiment of the present application, the second slide groove 432 also includes a transition groove section 432c, and the transition groove section 432c is connected between the first groove section 432a and the second groove section 432b, and the transition groove section 432c includes a transition groove surface 4325, and the transition groove surface 4325 is connected between the second groove surface 4322 and the fourth groove surface 4324. Intuitively speaking, the transition groove surface 4325 in the transition groove surface 4325 can be an inclined plane or an inclined arc surface. The transition groove surface 4325 can be used to make a smooth transition between the second groove surface 4322 and the fourth surface, ensuring that when the electronic device switches between the unfolded state and the folded state, the sliding process of the second swing arm 200 in the second slide groove 432 can be relatively smooth.

[0052] Furthermore, a plurality of second slide grooves 432 can be provided on the shells 400 on opposite sides of the base 100, and a plurality of second swing arms 200 can be provided on either side of the base 100. The plurality of second swing arms 200 correspond one-to-one with the plurality of second slide grooves 432 on the corresponding shells 400, and any second slide groove 432 can include the above-mentioned first groove section 432a, second groove section 432b and transition groove section 432c, so as to ensure that the cooperation smoothness between each second swing arm 200 and the corresponding second slide groove 432 is relatively good.
