The frame may include a first frame 111, a second frame 112, and a third frame 113. The first frame 111, the second frame 112, and the third frame 113 are surrounded around the substrate 114. The first frame 111 and the third frame 113 are disposed in parallel, and both ends of the second frame 112 are connected to the ends of the first frame 111 and the third frame 113, respectively. The first frame 111 is provided with a first connecting portion 13 at an end away from the second frame 112 for connecting with the folding mechanism 40. The third frame 113 is provided with a second connecting portion 14 at an end away from the second frame 112 for connecting with the folding mechanism 40.

In an embodiment, as shown in fig. 6, fig. 6 discloses a partially enlarged structural schematic view of a cross-sectional structure of an electronic device in an embodiment of the present application. The abutment 17 may be provided on a sidewall of the rear cover 12 close to the second housing 20a to avoid the abutment 17 occupying a space outside the rear cover 12, so that the surface of the rear cover 12 facing away from the accommodating space is smoother.

Alternatively, in an embodiment, the abutment 17 may be integrally formed with the rear cover 12. For example, when the rear cover 12 is made of a metal material, the abutting pieces 17 may be made of a metal material integrated with the rear cover 12, and after the rear cover 12 is formed by stamping or bending, the abutting pieces 17 on the rear cover 12 may be formed at the same time, so that the manufacturing process of the abutting pieces 17 is simplified, and the production efficiency of the housing assembly 100 is improved.
Alternatively, in another embodiment, the abutment member 17 may be connected to the rear cover 12 by bonding or welding. For example, the abutment 17 can be made using hot-melt glue. Specifically, a plurality of protrusions may be formed on the sidewall of the rear cover 12 by dispensing, and after cooling, the plurality of protrusions form solid abutments 17 for supporting and fixing between adjacent housings.
As shown in fig. 3 and 4, the number of the abutment pieces 17 provided on the rear cover 12 of the first housing 10 is at least two, for example, two, three, or four. At least two abutments 17 are provided at intervals in a direction perpendicular to the connecting direction of the at least two housings. That is, at least two abutments 17 are provided at intervals in the width direction of the first housing 10 to form a stable support at the junction of the first housing 10 and the second housing 20a, and to promote the abutting support force of the abutments 17 against the adjacent two housings.
The size of the suction acting force can be adjusted by adjusting the material and the size of the suction member 15 and the relative position of the arrangement, so that the requirement that the two parts of the mobile phone in the unfolded state are firmly fixed is met, and the size and the position of the rotary suction member 15 are easily pushed.
As shown in fig. 3 and 4, the engaging member 15 may be provided at an edge of the rear cover 12 of the first housing 10 near the second housing 20 a. Specifically, a magnet installation groove 122 is formed at an edge of the rear cover 12 adjacent to the second housing 20a, and the attraction member 15 is embedded in the magnet installation groove 122. The suction member 15 can be bonded and fixed in the magnet mounting groove 122, the suction member 15 can be clamped in the magnet mounting groove 122 in an interference fit manner with the magnet mounting groove 122, the suction member 15 can also be fixed in the magnet mounting groove 122 in a welding manner and the like, and the embodiment of the application is not specifically limited.
Wherein, the magnet mounting groove 122 can be located one side of the back cover 12 towards the accommodating space, on the one hand, the outer surface of the first casing 10 can be more flat, the cleaning and maintenance of the casing assembly 100 are facilitated, the absorbing part 15 can be further protected, and the absorbing part 15 is prevented from falling off under the action of external force. Alternatively, the magnet installation groove 122 may also be disposed on a side of the rear cover 12 away from the accommodating space, and this embodiment of the present application is not particularly limited.
Referring to fig. 7 and 8, fig. 7 and 8 respectively disclose a partial structure diagram of the first housing and a perspective structure diagram of the engaging member in another embodiment of the present application. The magnet mounting groove 122 has an opening on the side of the rear cover 12, a bottom wall 1221 opposite to the opening, and two opposite side walls 1222 connected between the opening and the bottom wall 1221, wherein a limiting portion 1223 is protruded on the two opposite side walls 1222, and the limiting portion 1223 is spaced from the bottom wall 1221 to form a clamping groove 1224. The engaging member 15 is provided with an engaging portion 152, and the engaging portion 152 is engaged in the engaging groove 1224. Because the size of the opening of the magnet installation groove 122 defined by the two limiting parts 1223 is smaller than the maximum size of the attraction piece 15 defined by the two clamping parts 152, the attraction piece 15 cannot be sucked out of the magnet installation groove 122 by the acting force between the two corresponding attraction pieces 15, and the installation stability of the attraction piece 15 can be further improved.
Alternatively, in another embodiment, two opposite side walls 1222 of the magnet installation groove 122 may be disposed obliquely to the bottom wall 1221 to form the magnet installation groove 122 in a dovetail shape, thereby achieving the limit of the attraction piece 15. Of course, in other embodiments, other shapes of the magnet installation groove 122 with a limiting function may also be adopted, and the embodiment of the present application is not particularly limited.
In one embodiment, the engaging member 15 disposed on the rear cover 12 may be a permanent magnet to reduce the complexity of controlling the housing assembly 100.
Because the space in the electronic device 000 is tight, in order to maximize the utilization of the space, the material of the permanent magnet is selected from a material with a large magnetic coefficient, for example, a soft magnetic material, a metal permanent magnetic material, a ferrite permanent magnetic material, and the like may be used, and the embodiment of the present application is not particularly limited.
Meanwhile, in order to avoid the permanent magnet occupying the thickness dimension of the housing assembly 100, the permanent magnet may be provided to be thin in the dimension perpendicular to the plane direction of the housing assembly 100, while the dimension of the permanent magnet is increased in the plane direction of the housing assembly 100.
Specifically, the permanent magnet may be disposed in a long strip shape, and an extending direction of the permanent magnet is perpendicular to a connecting direction of the at least two housings, that is, the extending direction of the permanent magnet is a width direction of the first housing 10. Thus, not only can a continuous suction acting force be formed in the width direction of the first shell 10, but also the suction strength can be increased to overcome the acting force of gravity on the shells, and the two shells are prevented from rotating relative to the folding mechanism 40, so that the two adjacent shells are positioned on the same plane, and further the flatness of the shell assembly 100 is improved.
Further, the number of the permanent magnets provided on the edge of the first housing 10 may be at least two, for example, two, three, or four, etc. The at least two permanent magnets are arranged at intervals along the connecting direction perpendicular to the at least two shells. That is, two at least permanent magnets set up along the parallel interval of width direction of first casing 10 to on the basis of guaranteeing permanent magnet overall length and actuation intensity, shorten the length of each permanent magnet, and then promote the structural strength of rectangular shape permanent magnet, avoid the permanent magnet to take place the fracture.
Alternatively, in another embodiment, the engaging element 15 disposed on the rear cover 12 may be an electromagnet, and when two adjacent shells are unfolded, the electromagnet on the two adjacent shells is powered on, so as to engage and fix the two adjacent shells, thereby improving the flatness of the shell assembly 100. When two adjacent shells are folded through the folding mechanism 40, the electromagnets on the two adjacent shells are powered off, so that the shell assembly 100 is pushed to be folded, the folding resistance is reduced, and the user experience is improved.
Wherein, the electro-magnet can be connected with the mainboard electricity of locating in the accommodation space, and then control the circular telegram and the outage of electro-magnet. For example, the folded state of the housing assembly 100 during the folding process can be detected and determined by using a gyroscope, a hall element, and other devices disposed in the electronic device 000, and then the main board determines whether to energize the electromagnet to generate magnetic force through the folded state.
With continuing reference to fig. 3, 4 and 9, fig. 9 discloses a schematic plan view of an electronic device according to another embodiment of the present application. The first mounting plate 1151 is disposed on a side of the first frame 111 close to the display module 400, for mounting the magnetic member 16. The third frame 113 is provided with a second mounting plate 1152 at a side close to the display module 400 for mounting the magnetic member 16. The magnetic members 16 on the first mounting plate 1151 and the magnetic members 16 on the second mounting plate 1152 are provided on opposite sides of the first housing 10 in a direction perpendicular to the direction in which the at least two housings are coupled. By providing the magnetic members 16 on the first and second opposite mounting plates 1151 and 1152, the first housing 10 can be fixed on both opposite sides of the first housing, so that the first housing 10 can be stressed uniformly, and the connection strength of the housing folded relatively can be enhanced, thereby improving the stability of the housing assembly 100.
In one embodiment, the magnetic member 16 may be disposed on a side of the mounting plate 115 facing away from the receiving space. Specifically, as shown in fig. 10, fig. 10 discloses an exploded partial enlarged structural diagram of the magnetic member and the mounting plate in fig. 3. A mounting groove 1153 may be formed on a surface of the mounting plate 115 facing away from the receiving space, and the magnetic member 16 may be inserted into the mounting groove 1153. The mounting groove 1153 may be a blind groove formed in the mounting plate 115, or may be a through groove penetrating through the mounting plate 115, which is not specifically limited in the embodiment of the present application.
Wherein, magnetism spare 16 can be the permanent magnet, and the permanent magnet can be bonded fixation in mounting groove 1153, and the permanent magnet can be located in mounting groove 1153 with mounting groove 1153 interference fit card, and the permanent magnet can also be fixed in mounting groove 1153 through modes such as welding in, this application embodiment does not do specifically and restricts.
Alternatively, the magnetic member 16 may be an electromagnet, as shown in fig. 11, where fig. 11 discloses a schematic structural diagram of an electromagnet in an embodiment of the present application. The electromagnet may include a magnetic attraction portion 161 and a flexible circuit board 163 electrically connected to the magnetic attraction portion 161. In this embodiment, the mounting groove 1153 is a through groove penetrating through the mounting plate 115, the magnetic attraction portion 161 is embedded in the mounting groove 1153, and the flexible circuit board 163 extends into the accommodating space. By arranging the electromagnets to fix the housing assembly 100, when the housing assembly needs to be fixed, the electromagnets on the two housings can be respectively electrified to be fixed, so that the electromagnets on the two housings can be attracted and fixed. When the two housings need to be rotated to be unfolded, the power can be cut off to eliminate the attraction force between the two housings, thereby facilitating the unfolding of the housing assembly 100.

The convex portion 434 is used for cooperating with the rotation shaft supporting frame 46 to prevent the supporting plate from separating from the rotation shaft supporting frame 46 to cause the bending damage of the reverse deformation of the display module 400.
Referring to fig. 18, the number of the positioning pieces 45 may be four, and the positioning pieces 45 are mounted on the rotating shaft support 46. Each connecting column 473 corresponds to the first rotating shaft module 41 and the second rotating shaft module 42 respectively, and is used for avoiding scratches caused by direct contact between the connecting column 473 and the supporting plate and the display module 400, limiting the supporting plate, and avoiding damage to the display module 400 caused by movement of the supporting plate along the axis of the rotating shaft. The locating tab 45 may be attached to the shaft support 46 by adhesive bonding, welding, snap-fit connection, or the like. In one embodiment, the positioning plate 45 may be integrated with the shaft support 46.
