Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of electronic equipment, and particularly relates to an electronic equipment. BACKGROUND

[0002] With the progress of technology, users' demand for foldable electronic equipment with large display area and strong portability gradually increases. Generally, a hinge mechanism is arranged in the foldable electronic equipment, and supports for supporting a screen in the electronic equipment are connected to each other through the hinge mechanism. In order to ensure the relative rotation between the two supports, a connecting arm is arranged in the hinge. In order to ensure that the connecting arm and the support can normally rotate and cooperate, the two need to have an assembly gap in the rotation axis direction. However, due to the aforementioned assembly gap, the two supports of the electronic equipment are prone to axial rubbing, which affects the user experience and reduces the service life of the electronic equipment. SUMMARY

[0003] The electronic equipment provided by the embodiments of the present application basically does not produce axial rubbing, and can improve the user experience and the service life of the electronic equipment.

[0004] The embodiments of the present application provide an electronic equipment including a base, a first support, a first connecting arm and an elastic assembly. The first support is used for supporting a screen of the electronic equipment. A first rotating end of the first connecting arm is rotationally connected with the base. A second rotating end of the first connecting arm is rotationally connected with a connecting portion of the first support. In the rotation axis direction of the first connecting arm, two ends of the elastic assembly are respectively abutted against a matching portion of the first support and the first connecting arm.

[0005] The embodiments of the present application disclose an electronic equipment. A first support of the electronic equipment is used for supporting a screen of the electronic equipment. A first rotating end of a first connecting arm is rotationally connected with a base. A second rotating end of the first connecting arm is rotationally connected with a connecting portion of the first support. The first support can form a rotating cooperation relationship with the base, so that the electronic equipment can be switched between an unfolded state and a folded state.

[0006] Meanwhile, in the rotation axis direction of the first connecting arm, two ends of the elastic assembly are respectively abutted against a matching portion of the first support and the first connecting arm. The elastic assembly can use the elastic extrusion of itself to extrude the first connecting arm and the first support in the rotation axis direction of the first connecting arm, and limit the relative movement of the two in the rotation axis direction of the first connecting arm. The purpose of preventing the electronic equipment from producing axial rubbing during use is achieved, and the user experience and the service life of the electronic equipment are improved.

[0007] In addition, during switching of the electronic device between the folded state and the unfolded state, the elastic assembly can be compressed under the action of an external force, so that the elastic assembly can prevent the first connecting arm and the first support from being limited from relative rotation, and the electronic device can still be normally switched between the folded state and the unfolded state.

[0031] The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

It is to be understood that the use of these terms herein is merely for distinguishing between the objects and the terms first and second are used arbitrarily and are interchangeable under appropriate circumstances.

The terms "and / or" between two or more statements or structures is used in their broadest and most general sense, and is used inclusively and not exclusivity.

[0033] As shown in Figures 1-17 The electronic device provided by the embodiments of the present application includes a base 100, a first support 211, a first connecting arm 311 and an elastic assembly 410, wherein the first support 211 and the first connecting arm 311 are both arranged on the same side of the base 100 and are connected to each other, so that the first support 211 can be in a rotating fitting relationship with the base 100 through the first connecting arm 311, and the electronic device has a deformation ability, so that the electronic device can be folded and unfolded, and the electronic device has a large display area and strong portability.

[0034] As described above, the first support 211 and the first connecting arm 311 are both arranged on the same side of the base 100, and correspondingly, the electronic device can further include a second support 212 and a second connecting arm 312, and the second support 212 and the second connecting arm 312 are arranged on the other side of the base 100, so that the second support 212 is in a rotating fitting relationship with the base 100 through the second connecting arm 312, wherein the assembly relationship between the second support 212 and the second connecting arm 312 and the base 100 can be different from the assembly relationship between the first support 211 and the first connecting arm 311 and the base 100. In one specific embodiment of the present application, optionally, the structures of the second support 212 and the second connecting arm 312 are respectively the same as those of the first support 211 and the first connecting arm 311, and the assembly relationship between the second support 212 and the second connecting arm 312 can also be arranged in correspondence with the first support 211 and the first connecting arm 311.

[0035] In addition, the electronic device can further be provided with a synchronous assembly. The synchronous assembly can make the first support 211 and the second support 212 form a synchronous rotating relationship, ensure that the unfolding angles of the parts on the first support 211 and the second support 212 are equivalent, and improve the display effect. The synchronous assembly includes a first synchronous arm 511 and a second synchronous arm 512, which are connected with the first support 211 and the second support 212 respectively, and the first synchronous arm 511 and the second synchronous arm 512 form a synchronous rotating relationship through a gear structure, so that the first synchronous arm 511 and the second synchronous arm 512 can synchronously rotate towards or away from each other.

[0036] In addition, the electronic device can further include a damping assembly. The damping assembly can make the first support 211 and the second support 212 in a hovering state, that is, between the folded state and the unfolded state, thereby expanding the use scenarios of the electronic device. The damping assembly can include a cam 520 mounted on the base 100 through an elastic return member 530, and at least one of the first synchronous arm 511 and the second synchronous arm 512 is provided with a concave-convex structure corresponding to the cam 520. Under the action of the elastic return member 530, the first synchronous arm 511 and the second synchronous arm 512 can remain in a relatively static state without being affected by other external forces, thereby making the electronic device present a hovering state.

[0037] In more detail, in the electronic device, the first support 211 is used to support the screen of the electronic device, so as to ensure that the screen can be stably supported and provide good display effect. Specifically, the first support 211 can be an approximately plate-shaped structure to provide reliable support for the screen, and the actual structure of the first support 211 can be determined according to actual needs, which is not limited here. Of course, considering that the first support 211 needs to rotate relative to the base 100, and there are relatively many connecting devices between the two, in order to reduce the design and processing difficulty of the electronic device, the size of the first support 211 can be relatively small, and the electronic device further includes a screen support part and the like to provide main support for the screen through a large-area screen support part, and the first support 211 only provides support for a smaller area of the middle region of the screen.

[0038] In the process of assembling the electronic device, the first rotating end 311a of the first connecting arm 311 is rotationally connected with the base 100, and the second rotating end 311b of the first connecting arm 311 is rotationally connected with the connecting part of the first support 211, so that the first support 211 can form a rotating fitting relationship with the base 100 through the first connecting arm 311. Specifically, the first connecting arm 311 is a rod-shaped structure as a whole, and the opposite ends thereof can be provided with corresponding rotating fitting structures, and are rotationally connected with the base 100 and the first support 211 respectively.

[0039] Further, the electronic device disclosed in the embodiments of the present application comprises the elastic component 410. In detail, the two ends of the elastic component 410 abut against the matching portion of the first support 211 and the first connecting arm 311 in the rotation axis direction of the first connecting arm 311. The elastic component 410 is a device or component with elastic capability. For example, the elastic component 410 can comprise a device formed of an elastic material such as rubber, or the elastic component 410 can further comprise a device such as a compression spring with relatively better elastic capability. The elastic component 410 can provide elastic force, so that the devices connected to the two opposite ends of the elastic component 410 can be compressed, thereby preventing the relative movement of the devices connected to the two opposite ends of the elastic component 410 in the elastic direction of the elastic component 410.

[0040] As described above, the first support 211 can be a plate-shaped structural member as a whole. The portion of the first support 211 that is rotationally connected to the first connecting arm 311 is the connecting portion, and the portion of the first support 211 that is connected to the elastic component 410 is the matching portion. In the actual structure of the first support 211, there can be no structural boundary between the connecting portion, the matching portion, and other portions that can be included in the first support 211, and the functions of these portions are only different.

[0041] Further, in the present application, by abutting the two ends of the elastic component 410 against the matching portion of the first support 211 and the first connecting arm 311, the first support 211 and the first connecting arm 311 have a tendency to move away from each other in the elastic direction of the elastic component 410. At the same time, due to the rotational matching structure between the first connecting arm 311 and the first support 211, only when there is no other force, the matching gap between the first connecting arm 311 and the first support 211 can be compressed to make the first connecting arm 311 and the first support 211 contact each other, but the first connecting arm 311 and the first support 211 will not be pushed by the elastic component 410 without limitation and move in the direction away from each other. When the matching gap between the first connecting arm 311 and the first support 211 is compressed by the elastic component 410 to be eliminated, the first connecting arm 311 and the first support 211 will not have relative movement in the rotation axis direction of the first connecting arm 311 when there is no other force.

[0042] Of course, during the arrangement of the elastic component 410, the elastic direction of the elastic component 410 can be inclined relative to the rotation axis direction of the first connecting arm 311. In this case, the elastic component 410 has a component force in the rotation axis direction of the first connecting arm 311, so that the elastic component 410 can provide elastic driving force for the first connecting arm 311 and the first support 211.

[0043] In another embodiment of the present application, the elastic direction of the elastic assembly 410 can be parallel to the rotation axis of the first connecting arm 311, so that the efficiency of the elastic assembly 410 can be improved, and the installation difficulty of the elastic assembly 410 can be reduced.

[0044] The electronic device disclosed in the embodiments of the present application comprises a first support 211 for supporting a screen of the electronic device, and a first connecting arm 311, wherein the first rotating end 311a of the first connecting arm 311 is rotationally connected with the base 100, and the second rotating end 311b of the first connecting arm 311 is rotationally connected with the connecting portion of the first support 211, so that the first support 211 can form a rotationally matched relationship with the base 100, and the electronic device can be switched between the unfolded state and the folded state.

[0045] Meanwhile, in the rotation axis direction of the first connecting arm 311, the two ends of the elastic assembly 410 abut against the matched portion of the first support 211 and the first connecting arm 311 respectively, so that the elastic assembly 410 can press the first connecting arm 311 and the first support 211 in the rotation axis direction of the first connecting arm 311 by using the elastic extrusion of the elastic assembly 410, and the relative movement of the first connecting arm 311 and the first support 211 in the rotation axis direction of the first connecting arm 311 is limited, so as to prevent the electronic device from being axially rubbed during use, and improve the user experience and the service life of the electronic device.

[0046] In addition, during the switching of the electronic device between the folded state and the unfolded state, the elastic assembly 410 can be compressed under the action of external force, so that the elastic assembly 410 can prevent the relative rotation between the first connecting arm 311 and the first support 211, and ensure that the electronic device can be normally switched between the folded state and the unfolded state.

[0047] As described above, one of the two ends of the elastic assembly 410 abuts against the first connecting arm 311, specifically, the first connecting arm 311 comprises a first side wall, the first side wall is a side wall between the first rotating end 311a and the second rotating end 311b of the first connecting arm 311, and the first side wall faces the matched portion of the first support 211, and one end of the elastic assembly 410 can specifically abut against the first side wall, which can reduce the installation difficulty of the elastic assembly 410, and improve the matching reliability between the first connecting arm 311 and the elastic assembly 410. It should be noted that in the embodiments of the present application, the first rotating end 311a and the second rotating end 311b of the first connecting arm 311 can be regarded as mass points, that is, the side surface between the two opposite ends of the first connecting arm 311 and facing the matched portion of the first support 211 is the first side wall, and the elastic assembly 410 can be arranged at any position between the first rotating end 311a and the second rotating end 311b.

[0048] Of course, in the process of arranging the elastic assembly 410, the regions in the first connecting arm 311 that respectively rotate with the base 100 and the first support 211 also need to be avoided to ensure that the first connecting arm 311 can form a rotating fit with the first support 211 and the base 100. More specifically, in order to make the overall stress condition of the first connecting arm 311 more uniform, in the embodiment of the present application, in the direction in which the first rotating end 311a points to the second rotating end 311b, one end of the elastic assembly 410 can abut against the middle of the first side wall. In this case, the force of the elastic assembly 410 can act on the middle of the first connecting arm 311 in the length direction of the first connecting arm 311, so that the stress conditions of the entire first connecting arm 311, especially the first rotating end 311a and the second rotating end 311b of the first connecting arm 311, are basically consistent, thereby preventing the first connecting arm 311 from tilting when the first connecting arm 311 is subjected to the force of the elastic assembly 410 and the first support 211 moves relative to the first connecting arm 311 along the rotating axis of the first connecting arm 311, and adversely affecting the smoothness of the rotating action of the first connecting arm 311.

[0049] As described above, the elastic assembly 410 can include a device with elastic capability. In the embodiment of the present application, more specifically, the elastic assembly 410 includes a spring and a limiting shaft 420. The spring has relatively good elastic capability and a relatively long service life. Meanwhile, by providing the spring with the limiting shaft 420 and sleeving the spring on the limiting shaft 420, the limiting shaft 420 can provide guiding and limiting functions for the spring to prevent the spring from being bent and deformed during compression, further improve the service life of the spring, and improve the reliability of the electronic device.

[0050] In the process of assembling the elastic assembly 410 including the above structure, in order to improve the installation reliability of the elastic assembly 410, the first support 211 is provided with a first shaft seat 221, and the first side wall is provided with a second shaft seat 321. The first shaft seat 221 and the second shaft seat 321 are both provided with grooves to provide installation space for the limiting shaft 420. Based on this, the opposite ends of the limiting shaft 420 are respectively installed in the grooves of the first shaft seat 221 and the second shaft seat 321, thereby making the limiting shaft 420 have relatively high installation reliability. Meanwhile, in order to ensure that the elastic assembly 410 can normally provide elastic compression, the limiting shaft 420 is movably connected with at least one of the first shaft seat 221 or the second shaft seat 321 in the axial direction of the limiting shaft 420.

[0051] In other words, the limiting shaft 420 can move along its axial direction relative to one of the first support 211 and the first connecting arm 311, in which case, the distance between the first shaft seat 221 and the second shaft seat 321 in the axial direction of the limiting shaft 420 can be changed, so as to enable the spring to drive the first support 211 and the first connecting arm 311 to move relative to each other in the aforementioned direction, so as to press the first support 211 and the first connecting arm 311, so as to eliminate the fitting gap therebetween, and prevent the first support 211 and the first connecting arm 311 from being twisted along the axial direction of the limiting shaft 420.

[0052] In addition, considering that the first support 211 and the base 100 are connected through the first connecting arm 311, and the first connecting arm 311 and the first support 211 can have inconsistent trajectories during relative rotation with respect to the base 100, based on this, as shown in Figure 6 In the direction perpendicular to the axial direction of the limiting shaft 420, or in the radial direction of the limiting shaft 420, at least one of the first shaft seat 221 and the second shaft seat 321 can be movably connected with the limiting shaft 420, so as to compensate for the inconsistent trajectories of the first support 211 and the first connecting arm 311.

[0053] Based on the above, further, the limiting shaft 420 can be movably connected with the first connecting arm 311 in the radial direction of the limiting shaft 420. Alternatively, the second shaft seat 321 is provided with a sliding groove 321a, so that the limiting shaft 420 is movably connected with the first support 211 in the radial direction of the limiting shaft 420, and the limiting shaft 420 is movably connected with the sliding groove 321a, on the one hand, the installation difficulty of the limiting shaft 420 can be reduced, and it is ensured that the arrangement of the limiting shaft 420 will not hinder the normal fitting relationship between the first connecting arm 311 and the first support 211, on the other hand, by movably connecting one end of the limiting shaft 420 with the first support 211, the installation stability of the limiting shaft 420 can be improved.

[0054] Specifically, the sliding groove 321a can be recessed in the second shaft seat 321, and the specific extension direction and extension size of the sliding groove 321a can be determined according to the specific parameters of the relative motion trajectory between the first connecting arm 311 and the first support 211, so as to ensure that the sliding groove 321a can provide a movable space for the limiting shaft 420.

[0055] Meanwhile, in order to prevent the limiting shaft 420 from moving uncontrollably in the sliding groove 321a and adversely affecting the movement reliability of the first connecting arm 311 and the first support 211, the extension size of the sliding groove 321a can also be designed based on the stroke of the limiting shaft 420 when the first support 211 and the first connecting arm 311 move during the design of the sliding groove 321a, so as to ensure that when the first support 211 and the first connecting arm 311 move synchronously to a position where they cannot continue to move relative to the base 100, the sliding groove 321a can provide a limiting action for the limiting shaft 420.

[0056] Specifically, the electronic device has a folded state and an unfolded state. When the electronic device is in the folded state, the limiting shaft 420 is located at one end of the sliding groove 321a, and when the electronic device is in the unfolded state, the limiting shaft 420 is located at the other end of the sliding groove 321a, so that the cooperation state between the limiting shaft 420 and the sliding groove 321a corresponds to the state of the electronic device. When the first support 211 and the first connecting arm 311 have relative movement capability, the limiting shaft 420 and the sliding groove 321a also have relative movement capability, and when the movement of the first support 211 and the first connecting arm 311 is limited, the limiting shaft 420 and the sliding groove 321a are also in a limited movement state, thereby further improving the reliability of the electronic device and the synergy between components.

[0057] In the case of using the first shaft seat 221 and the second shaft seat 321 to provide mounting action for the limiting shaft 420, the spring can be mounted into the first shaft seat 221 and the second shaft seat 321 together with the limiting shaft 420. In another embodiment of the present application, one end of the spring can abut against the end face of the first shaft seat 221 facing the second shaft seat 321, and the other end of the spring can abut against the end face of the second shaft seat 321 facing the first shaft seat 221. In other words, the spring is mounted outside the groove of the first shaft seat 221 and the second shaft seat 321, or in other words, the spring is completely located in the region between the first shaft seat 221 and the second shaft seat 321. In the case of using this technical solution, when the first connecting arm 311 moves relative to the base 100, even if the position of the limiting shaft 420 changes relative to the first connecting arm 311, the spring will not move relative to the first connecting arm 311, thereby making the installation stability of the spring relatively high, ensuring that the spring can always provide elastic extrusion action for the first support 211 and the first connecting arm 311, and improving the reliability of the electronic device.

[0058] As described above, the elastic assembly 410 can include the spring and the limiting shaft 420 to improve the stability of the spring by using the limiting shaft 420. In another embodiment of the present application, the elastic assembly 410 can no longer include the limiting shaft 420, that is, the spring of the elastic assembly 410 no longer uses the limiting shaft 420 to provide the guiding and limiting functions. On this basis, in order to still have relatively high installation stability of the spring, as shown in Figure 14 As shown, the first locating column 222 is arranged on the fitting part of the first support 211, and the second locating column 322 is arranged on the first side wall of the first connecting arm 311. The first locating column 222 and the second locating column 322 are oppositely and spacedly arranged, so that the opposite ends of the spring can be respectively sleeved on the first locating column 222 and the second locating column 322 to provide the locating function for the spring and ensure the relatively high stability of the spring. Specifically, the first locating column 222 can be formed together with the first support 211, and similarly, the second locating column 322 can be formed together with the first connecting arm 311, so as to reduce the processing difficulty of the first locating column 222 and the second locating column 322 and improve the structural reliability of the first locating column 222 and the second locating column 322.

[0059] In addition, in the case of using the above technical solutions, since the limiting shaft 420 is not arranged in the spring, the opposite ends of the spring have the relative movement in the direction perpendicular to the elastic direction of the spring, so that the spring is deformed to adapt to the difference between the movement trajectories of the first connecting arm 311 and the first support 211. In addition, the first locating column 222 and the second locating column 322 can be respectively fixed on the first support 211 and the first connecting arm 311, which can reduce the design and installation difficulty of the device for positioning the spring in the electronic device, and can also reduce the number of moving parts in the electronic device and the failure rate of the electronic device.

[0060] As described above, in the case of using the first locating column 222 and the second locating column 322 to provide the locating function for the spring, the opposite ends of the spring will also have the relative movement in the direction perpendicular to the rotation axis direction of the first connecting arm 311 with the relative movement of the first support 211 and the second connecting arm 312, so that the spring is deformed. Based on the above, in the process of designing the electronic device disclosed in the above embodiment, the electronic device can be designed to have the spring in a straight line structure when the electronic device is in the unfolded state or the folded state, and the opposite ends of the spring can continuously move away from each other in the direction perpendicular to the rotation axis direction of the first connecting arm 311 during the switching of the electronic device to the folded state or the unfolded state.

[0061] In another embodiment of the present application, in order to reduce the distance of the opposite movement between the opposite ends of the spring and reduce the maximum deformation degree of the spring, the axes of the first positioning column 222 and the second positioning column 322 are arranged to be staggered with each other when the electronic device is in the folded state and the unfolded state. Of course, the staggered directions of the first positioning column 222 and the second positioning column 322 are opposite when the electronic device is in the folded state and the unfolded state, respectively.

[0062] Specifically, the electronic device further includes a hovering state, which is an intermediate state between the folded state and the unfolded state of the electronic device. When the electronic device is in the hovering state, the axes of the first positioning column 222 and the second positioning column 322 are arranged to be collinear. That is, during the switching of the electronic device from the hovering state to the folded state (and the unfolded state), the axes of the first positioning column 222 and the second positioning column 322 are switched from the collinear state to the staggered state, and vice versa, during the switching of the electronic device from the folded state (and the unfolded state) to the hovering state, the axes of the first positioning column 222 and the second positioning column 322 are switched from the staggered state to the collinear state.

[0063] More specifically, taking the example that the first connecting arm 311 rotates 90° relative to the base 100 when the electronic device is switched between the folded state and the unfolded state, the electronic device can be in the above-mentioned hovering state, and the first connecting arm 311 can be rotated by an angle of 45° relative to the base 100. In other words, when the electronic device is in the above-mentioned hovering state, the angle through which the first connecting arm 311 is rotated relative to the base 100 is half of the maximum rotation angle of the first connecting arm 311 relative to the base 100, which can further reduce the deformation amplitude of the spring and thus improve the service life of the spring.

[0064] As described above, the elastic direction of the elastic assembly 410 can be arranged to be inclined relative to the rotation axis of the first connecting arm 311, or the elastic direction of the elastic assembly 410 can be parallel to the rotation axis of the first connecting arm 311, so as to improve the action efficiency of the elastic assembly 410. On this basis, the axis of the elastic assembly 410 can be further designed to be collinear with the rotation axis of the second end of the first connecting arm 311, that is, the elastic assembly 410 is installed at the position where the second end of the first connecting arm 311 forms a rotating connection relationship with the first support 211.

[0065] Based on the above embodiment, optionally, the elastic assembly 410 comprises a spring, and the electronic device comprises the first positioning column 222 and the connecting piece, wherein the first positioning column 222 is fixed to the fitting part of the first support 211, the connecting piece comprises the rotating shaft 430 and the second positioning column 322, the second positioning column 322 is fixed to one end of the rotating shaft 430, the second rotating end 311b of the first connecting arm 311 is rotationally connected to the connecting part of the first support 211 through the rotating shaft 430, and one end of the spring is sleeved on the first positioning column 222, and the other end of the spring is sleeved on the second positioning column 322, so as to provide the auxiliary action for the installation stability of the connecting piece by the spring while providing the positioning action for the spring by the connecting piece and the first positioning column 222, to ensure that the rotating fitting relationship between the first connecting arm 311 and the first support 211 is relatively stable, and to ensure that the installation reliability of the spring is relatively high. In the case of adopting the above technical solution, the number of components in the electronic device can be further reduced, thereby further reducing the assembly difficulty and failure rate of the electronic device.

[0066] Specifically, the connecting piece can be formed in an integral molding manner, by making the connecting piece extend into the second end of the first connecting arm 311, and making the second positioning column 322 of the connecting piece extend out of the first connecting arm 311 to cooperate with the spring. And by making the end of the rotating shaft 430 of the connecting piece away from the second positioning column 322 extend into the first support 211, the connecting piece can be made to cooperate with the first positioning column 222, and provide the action of “rotating shaft” for the rotation of the first connecting arm 311. Or, a part of the first support 211 can also extend into the through hole in the second end of the first connecting arm 311 for installing the connecting piece, and serve as a “rotating shaft” together with the connecting piece and the first positioning column 222, to ensure that the rotating fitting relationship between the first connecting arm 311 and the first support 211 is relatively stable.

[0067] In the above embodiment, the elastic component 410 is pressed between the first connecting arm 311 and the first support 211. Alternatively, the elastic component 410 can be arranged on the side of the first connecting arm 311 away from or towards the display screen. In another embodiment of the present application, the matching part of the first support 211 is provided with a recessed avoiding space from the surface, and the elastic component 410 is accommodated in the avoiding space. Thus, the space originally occupied by the first support 211 is used to provide installation space for the elastic component 410. On the one hand, the elastic component 410 does not further occupy additional installation space, so that the installation space inside the electronic device is not further limited. On the other hand, the first support 211 can be further lightened, so that the weight of the electronic device is reduced. At the same time, by accommodating the elastic component 410 in the avoiding space on the first support 211, after the electronic device is assembled, i.e. after the screen and the shell and other structures are respectively arranged on the two opposite sides of the first support 211, the elastic component 410 can be provided with better limiting effect, so that the elastic component 410 is further prevented from being bent and the like during work, and the reliability of the elastic component 410 is improved.

[0068] The embodiments of the present application are described above in combination with the drawings, but the present application is not limited to the above specific embodiments, and the above specific embodiments are only illustrative but not restrictive. Those skilled in the art can make many forms under the inspiration of the present application without departing from the scope of the present application and the protection scope of the claims.
