Thus, a feature defined as "first," "second," may explicitly or implicitly include at least one such feature. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless explicitly specified otherwise.

It is to be understood that the names of the "first housing", the "second housing", and the "housing" may be interchanged, for example, the "first housing" may also be referred to as the "second housing".

Specifically, referring to fig. 3 and 4, fig. 4 is an exploded view of the housing shown in fig. 3.

The housing 100 may be two, such as a first housing 101 and a second housing 102. Each of the housings 100 may include a housing body 10 and a connection member 20. The housing body 10 is used for carrying the display module 300, and can also be used for mounting electronic components such as a circuit board and a battery. The connector 20 is mounted on the housing body 10 for connection with the folding assembly 200 to achieve connection of the housing 100 with the folding assembly 200.

Specifically, referring to fig. 4, the housing body 10 may include a bottom plate 11, a side wall 12, and a fixing plate 13. The edge of the bottom plate 11 may be provided with a side wall 12, i.e. the side wall 12 may surround the edge of the bottom plate 11. So that the bottom plate 11 and the side wall 12 form a receiving space for receiving electronic components such as a camera, a circuit board, a battery, a display module 300, and the like. The fixing plate 13 is disposed opposite to the bottom plate 11 and is connected and fixed to the side wall 12. Namely, the side wall 12 is arranged around the fixing plate 13 and fixed with the fixing plate 13 to form a middle frame. The fixing plate 13 may divide the receiving space into two, forming a first receiving space and a second receiving space. The first receiving space is located between the bottom plate 11 and the fixing plate 13 and is used for receiving electronic components such as a camera, a circuit board, and a battery, and the second receiving space is located on a side of the fixing plate 13 away from the bottom plate 11 and is used for receiving the display module 300.

The side wall 12 surrounds the edge of the bottom plate 11 and extends to the same side of the bottom plate 11. The side wall 12 is broken to form an opening at the side of the bottom plate 11 where the mounting portion 14 is provided, so as to give way to the folding assembly 200. That is, the side wall 12 is provided around three sides of the bottom plate 11, and the mounting portion 14 is provided on the remaining one side, and the side wall 12 is not provided, to form an opening.

The side walls 12 have a smaller wall thickness on both sides of the opening than elsewhere to give way to the folding assembly 200. It will be appreciated that the opening may be more than one and may be two or three. For example, in fig. 4, the side walls 12 may be provided around two opposite edges of the bottom plate 11, with an opening being formed on each of the other two edges. Of course, the side walls 12 may also be provided around two adjacent edges of the bottom plate 11, with an opening being formed on each of the other two edges.

In one embodiment, the bottom plate 11 and the sidewalls 12 are a unitary structure, and the sidewalls 12 are made of the same material as the bottom plate 11.

In one embodiment, referring to fig. 4, the sidewall 12 and the substrate 511 are a unitary structure,

the substrate 511 may be made of the same material as the sidewall 12. In one embodiment, the substrate 511 does not cover the bottom plate 11 at the opening to give way to the foldable assembly 200, so that part of the structure of the foldable assembly 200 is placed on the bottom plate 11.

Referring to fig. 4 and 5, fig. 5 is a perspective view of a connecting arm in the housing shown in fig. 4.

The connector 20 is used to connect with the folding assembly 200. The connecting member 20 may be plural, for example, the connecting member 20 may be 2, and is a first connecting member 201 and a second connecting member 202.

Referring to fig. 6, fig. 6 is a perspective view of the folding assembly shown in fig. 3.

The folding assembly 200 may include a supporting plate 30 (e.g., a first supporting plate 301 and a second supporting plate 302), a supporting frame 40, and a hinge module 50 (e.g., a first hinge module 501 and a second hinge module 502). Specifically, the support frame 40 is disposed between two adjacent housings 100, for example, the support frame 40 is disposed between a first housing 101 and a second housing 102. The first hinge module 501 and the second hinge module 502 of the hinge module 50 are respectively located at two ends of the supporting frame 40 and are respectively fixedly connected to the supporting frame 40. The hinge module 50 is disposed between two adjacent housings 100 and respectively connects the two adjacent housings 100, so that the two adjacent housings 100 can be folded when the hinge module 50 rotates. For example, the first hinge module 501 and the second hinge module 502 can connect the first casing 101 and the second casing 102 together. The first support plate 301 and the second support plate 302 of the support plate 30 are symmetrically arranged and located at two opposite sides of the support frame 40. The first supporting plate 301 is located between the first hinge module 501 and the second hinge module 502, and is rotatably connected to the first casing 101. The first supporting plate 301 is further rotatably connected to the first hinge module 501 and the second hinge module 502, respectively.

The hinge module 50 may include a base 51, two rotating arms 52 (e.g., a first rotating arm 520a and a second rotating arm 520 b), and a limiting member 53, where the two rotating arms 52 are respectively rotatably connected to the base 51 on different and parallel rotating shafts, and the limiting member 53 is fixedly connected to the base 51, and is used to prevent the first rotating arm 520a and/or the second rotating arm 520b from being separated from the base 51, so as to prevent any rotating arm 52 of the electronic device 1000 from being separated from the base 51 in the folded state of the whole device.

Referring to fig. 12, fig. 12 is a perspective view of a base in an embodiment of the folding module shown in fig. 11.

Alternatively, the susceptor 51 may include a base plate 511, a first base 512 and a mounting plate 513, wherein the base plate 511 and the mounting plate 513 are respectively located on two opposite side surfaces of the first base 512, and the base plate 511 and the mounting plate 513 are respectively located on different and mutually parallel planes and are fixedly connected to the first base 512. The base plate 511 is provided with fixing holes 5110, and a fixing member such as a screw is inserted through the fixing holes 5110 and the fixing portion 410 to achieve the fixed connection with the main support plate 41 and the support frame 40. Specifically, the fixing holes 5110 include a first fixing hole 5110a disposed on the substrate 511 of the first rotating shaft module 501, and the first fixing hole 5110a corresponds to the first fixing portion 410a, so as to realize the fixed connection between the first rotating shaft module 501 and the supporting frame 40; the fixing hole 5110 further includes a second fixing hole 5110b disposed on the substrate 511 of the second hinge module 502, and the second fixing hole 5110b corresponds to the second fixing portion 410b to achieve the fixed connection between the second hinge module 502 and the supporting frame 40.

Referring to fig. 9 to 12, the first base 512 may include a first face 5120 away from the substrate 511, and the mounting plate 513 may include a second face 5130 parallel to the first face 5120, wherein the first face 5120 and the second face 5130 are arranged in a step-like manner, that is, the base 51 includes a first face 5120 and a second face 5130 which are arranged in a step-like manner. The position-limiting member 53 is fixed on the second surface 5130, and a side of the position-limiting member 53 away from the second surface 5130 is flush with the first surface 5120 or slightly lower than the first surface 5120, so as to prevent the display module 300 from being bumpy and affecting the touch of the display module 300 when the display module 300 is attached to the hinge module 50.

Optionally, two first pivoting grooves 5121 (such as a first sliding groove 5121a and a second sliding groove 5121 b) are disposed on a side surface of the first base 512 connected to the substrate 511, wherein two ends of the first pivoting groove 5121 are respectively connected to the first surface 5120, so that the first rotating arm 520a and the second rotating arm 520b can be screwed into or at least partially selected from the first pivoting grooves 5121. The first rotary arm 520a can be received in and slidably coupled to the first sliding groove 5121a, and the second rotary arm 520b can be received in and slidably coupled to the second sliding groove 5121b, so that the first rotary arm 520a and the second rotary arm 520b can move relative to the base 51. With such a design, the dimensions of the first and second pivoting arms 520a and 520b in the pivoting axis direction can be reduced, and the space utilization rate inside the electronic device 1000 can be improved.

Further, the first pivot groove 5121 is arc-shaped, that is, the first sliding groove 5121a and the second sliding groove 5121b are arc-shaped, and the first rotating arm 520a and the second rotating arm 520b can slide along the first sliding groove 5121a and the second sliding groove 5121b, so that the first rotating arm 520a and the second rotating arm 520b can rotate relative to the base 51. It is understood that when the ends of the first and second rotating arms 520a and 520b far from the base 51 are close to each other (as shown in fig. 11), the electronic device 1000 is in the folded state, and when the ends of the first and second rotating arms 520a and 520b far from the base 51 are far from each other and are substantially located on the same plane (as shown in fig. 10), the electronic device 1000 is in the unfolded state.

Optionally, the first base portion 512 further has two limiting grooves 5122 formed thereon and located on the first surface 5120, such as a first limiting groove 5122a and a second limiting groove 5122b, wherein the first limiting groove 5122a is communicated with the first sliding groove 5121a, and the second limiting groove 5122b is communicated with the second sliding groove 5121b. The first limiting groove 5122a is located at an end of the first sliding groove 5121a far away from the second sliding groove 5121b, and the second limiting groove 5122b is located at an end of the second sliding groove 5121b far away from the first sliding groove 5121 a. The limiting members 53 are respectively held and received in the first limiting groove 5122a and the second limiting groove 5122b, and are used for blocking the first rotating arm 520a and the second rotating arm 520b from being separated from the base 51 in the folded state of the electronic device 1000.

Referring to fig. 9 and 10, specifically, the first limiting groove 5122a is communicated with an end of the first sliding groove 5121a far away from the second sliding groove 5121b, and the second limiting groove 5122b is communicated with an end of the second sliding groove 5121b far away from the first sliding groove 5121 a. It can be understood that when the first rotating arm 520a and the second rotating arm 520b are screwed into the end of the first sliding groove 5121a communicating with the first limiting groove 5122a and the end of the second sliding groove 5121b communicating with the second limiting groove 5122b respectively, due to the supporting function of the base plate 511, when the first rotating arm 520a and the second rotating arm 520b are in the same plane, the first rotating arm 520a and the second rotating arm 520b cannot rotate continuously, so as to limit the first rotating arm 520a and the second rotating arm 520 b.

When the electronic device 1000 is in a folded state, that is, the first rotating arm 520a and the second rotating arm 520b are parallel to each other, the first slider 5222 of the first rotating arm 520a and the second rotating arm 520b is partially received in the corresponding first sliding groove 5121a and the second sliding groove 5121b, and it can be understood that when the electronic device 1000 falls, the first rotating arm 520a and the second rotating arm 520b are easily separated from the base 51.
