In this embodiment, the mating structure of the frame assembly 110 and the base 134 is further defined, optionally, the frame assembly 110 is provided with a mounting groove 116, a portion of a groove sidewall of the mounting groove 116 is obliquely disposed to form a first inclined surface 1162, the base 134 is formed with a second inclined surface 1348, the first inclined surface 1162 and the second inclined surface 1348 are opposite and are arranged at intervals, the inclination directions of the first inclined surface 1162 and the second inclined surface 1348 are the same, and a third included angle D is formed between the first inclined surface 1162 and a plane on which the display surface 159 of the second display screen 150 is located, and the third included angle D is an acute angle. That is, the mounting groove 116 is a flared structure. This arrangement makes the clearance between the first inclined surface 1162 and the second inclined surface 1348 form an inner flare with a smaller outside and a larger inside, or the interval of the clearance between the first inclined surface 1162 and the second inclined surface 1348 is equal, so that the fit gap between the frame assembly 110 and the rear cover 130 can be effectively reduced, which is beneficial to improving the appearance streamline and the aesthetic property of the electronic device 100.

Optionally, the third included angle D formed between the first inclined surface 1162 and the plane on which the display surface 159 of the second display screen 150 is located is greater than 0 ° and less than or equal to 45 °. For example, the third included angle D includes 5 °, 10 °,15 °, 20 °, 25 °, 30, 35 °, and so on, which are not illustrated herein.

Optionally, the electronic device 100 includes a frame assembly 110, a first display 120, a second display 150, and a rear cover 130. A rear cover 130 base 134 and a leather layer 136. The second display 150 is a secondary screen.

The sub-screen is glued, pressure-maintained and adhered to the base 134, and the flexible circuit board 156 of the second display screen 150 is attached to the back surface of the rear cover 130. The rear cover 130 and the auxiliary screen are combined to form the rear cover 130 part of the upper body of the upper and lower folding machine.

The rear cover 130 of the present application can meet the requirements of users on the leather rear cover 130, and meanwhile, optimize the layout mode of the electronic device 100, which is beneficial to reducing the thickness of the electronic device 100. The requirements of manufacturability, structural reliability and appearance are also met.

The secondary screen includes a light-transmissive cover plate 152 (e.g., the light-transmissive cover plate 152 includes a glass cover plate), a display portion 154, a driver chip 158, and a connector 160.

As shown in fig. 4, 5, 6, 7, 8, 9 and 10, the lower half of the rear cover 130 is firstly glued to form an annular glue layer 180, meanwhile, the flexible circuit board 156 of the auxiliary screen is folded back and fixed in the auxiliary screen in advance, then the auxiliary screen is assembled on the rear cover 130 along the vertical direction, and then the auxiliary screen is put into a pressure maintaining clamp for maintaining pressure for a certain time, and is taken out from the pressure maintaining clamp after the glue is completely solidified. After being taken out, the reversely folded flexible circuit board 156 is folded back and stuck in the corresponding fixing groove of the rear cover 130. And then the decorative ring of the camera 190, the double-sided adhesive of the rear cover 130 and the like are assembled.

Finally, the connector 160 is buckled with the connector 160 on the main board of the electronic device 100, so that the electric connection between the auxiliary screen and the whole machine is realized, and the whole rear cover 130 and the second display screen 150 are adhered with the frame body assembly 110 through double faced adhesive tape.

The second display 150 includes a light-transmitting cover plate 152, a display portion 154, a flexible circuit board 156, and a driving chip 158.

In the second display 150, the driving chip 158 is the thickest, and the position of the driving chip 158 determines the thickness bottleneck of the rear cover 130. In this application, as shown in fig. 9 and 10, the driving chip 158 is laid out on the flexible circuit board 156 of the sub-screen, and the driving chip 158 and the display portion 154 are juxtaposed on one side of the light-transmitting cover plate 152. This arrangement can effectively reduce the thickness of the rear cover 130. Because the driving chip 158 is arranged on the flexible circuit board 156, the driving chip 158 can be arranged at any position in the whole machine according to the stacking condition in the whole machine.

As shown in fig. 13, the rear cover 130 cooperates with the sub-screen in the X-direction (horizontal direction) and Y-direction (vertical direction), and the tail position requires an angle of draft angle B (i.e., the groove side walls of the groove 1342 are required to be inclined), for example, the angle B is 88.5 ° due to the requirement of demolding the base 134. In this application, as shown in fig. 13, when the transparent cover plate 152 is cut, the cutter is inclined at an angle such that a second included angle C formed between the side wall of the transparent cover plate 152 and the plane where the end surface of the transparent cover plate 152 exposes the leather layer 136 is not a right angle, for example, the second included angle C is 86.5 °. Thus, after the base 134 and the second display 150 are assembled, an inner flare gap with a smaller outside and a larger inside is formed between the groove side wall of the groove 1342 and the side wall of the light-transmitting cover plate 152, and this arrangement can effectively reduce the fit gap between the rear cover 130 and the auxiliary screen. Meanwhile, the glue can be contained by the device, and the glue overflow is reduced.

In addition, as shown in fig. 4 and 5, the rear cover 130 is matched with the sub-screen in the Z direction, and a plurality of support bosses 1344 are uniformly provided on the rear cover 130 throughout the entire circle. The supporting boss 1344 is in direct contact with the light-transmitting cover plate 152 of the auxiliary screen, so that the auxiliary screen can be effectively prevented from sinking during pressure maintaining, and the problem of scraping hands caused by the height difference between the auxiliary screen and the rear cover 130 is avoided. Meanwhile, enough glue height can be ensured, and the bonding strength is ensured. And when the glue path is overlapped with the supporting boss 1344, a glue overflow groove 1346 is arranged near the supporting boss 1344 to prevent the glue from overflowing to the appearance surface.

In the test of the falling reliability of the whole machine, when the whole machine is in a folded state and the grounding position is the left and right lower corners of the auxiliary screen, the light-transmitting cover plate 152 of the auxiliary screen is extremely easy to crack.

In this application, the electronic device 100 includes a frame assembly 110, where the frame assembly 110 is provided with a mounting groove 116, a portion of a groove sidewall of the mounting groove 116 is obliquely disposed to form a first inclined surface 1162, a portion of the base 134 corresponding to the first inclined surface 1162 forms a second inclined surface 1348, inclination directions of the first inclined surface 1162 and the second inclined surface 1348 are the same, a third included angle D is formed between the first inclined surface 1162 and a plane where the display surface 159 of the second display screen 150 is located, and the third included angle D is greater than 0 ° and less than or equal to 45 °.

The frame assembly 110 is raised synchronously to be close to the outer surface of the rear cover 130. Thus, when the electronic device 100 falls, although the rear cover 130 is still in contact with the ground first, since the frame assembly 110 is substantially flush with the rear cover 130, on one hand, the sinking degree of the rear cover 130 can be effectively reduced, and on the other hand, after the rear cover 130 is deformed and sagged, the frame assembly 110 is grounded before the auxiliary screen, and the frame assembly 110 is made of a harder material and cannot be deformed further, so that the ground impact can be effectively carried, and the auxiliary screen is protected.

In the related art, the frame assembly is located below the rear cover. Optionally, the surface stress of the auxiliary screen is reduced from 1943MPa to 814MPa, and through experimental tests, the mobile phone in the related technology is placed in an iron drum with the depth of 1 meter in a folded state for rolling test, and the auxiliary screen is cracked within 5 times of falling test.

The mobile phone is placed in a folding state in an iron barrel with the depth of 1 meter for rolling test, and the secondary screen is not cracked after the mobile phone is subjected to drop test for times. The rear cover 130 and the auxiliary screen of the present application are combined together by using glue, and may also be assembled together by other forms, such as double faced adhesive tape, fastening position, interference fit, etc. As shown in fig. 13, the light-transmitting cover plate 152 includes a light-transmitting body 1522 and a film 1524, the light-transmitting body 1522 is exposed on the leather layer 136, the film 1524 is disposed on one side of the light-transmitting body 1522 facing the bottom of the groove 1342, and the supporting boss 1344 abuts against the film 1524.
