[0004] The shape of the middle frame needs to match the shape of the battery cover. In the above-mentioned terminal device, the opening of the mounting holes will affect the appearance of the middle frame. Therefore, how to take into account the installation of some buttons and the aesthetic appearance in the case of a narrow frame is a problem that needs to be solved. Utility Model Content

[0028] Here, the technical solutions in the embodiments (or "implementations") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0029] If there are terms related to directional indications or positional relationships in the embodiments of this application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first" and "second" in the embodiments of this application are only used for the purpose of convenience of description and should not be understood as indicating or implying relative importance.

[0030] See also Figure 1 、 Figure 5 、 Figure 8 and Figure 10 Combined with Figure 3 and Figure 4 The present application discloses a middle frame assembly. The middle frame assembly includes a middle frame 1, a first side key 2, a second side key 3 and a latch 4.

[0031] See also Figure 3 、 Figure 8 and Figure 10 Combined with Figure 4 , the side of the middle frame 1 includes a first mounting portion 11 and a second mounting portion 12. The second mounting portion 12 protrudes toward the back of the middle frame relative to the first mounting portion 11 and includes a curved surface 19, so that the back of the middle frame 1 is located on the inner side of the first mounting portion 11 in the direction perpendicular to the thickness of the middle frame. As a result, the side of the middle frame 1 is a curved surface that can match the battery cover. Some scenarios for forming the curved surface 19 are: the second side key 3 is a button with a larger width, for example, a button that integrates fingerprint function and power function and has a larger width. When the second side key 3 is wider, in order to avoid increasing the overall thickness of the middle frame 1 due to compatibility with the second side key 3, the second mounting portion 12 is protruded.

[0032] See also Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 , based on the distance from the second mounting portion 12, the first side key 2 includes a proximal end 21 and a distal end 22. The middle frame 1 also includes a proximal mounting hole 13 and a distal mounting hole 14. The proximal mounting hole 13 corresponds to the area where the first mounting portion 11 and the second mounting portion 12 are connected, see Figure 3 、 Figure 5 and Figure 8The proximal mounting hole 13 also extends from the front surface of the middle frame 1 toward the interior of the middle frame 1 , and its depth is less than the thickness of the middle frame 1 , that is, the proximal mounting hole 13 is formed by opening from the front surface of the middle frame 1 but does not penetrate the middle frame 1 .

[0033] The first mounting portion 11 includes a mounting slot. The mounting slot is connected to the proximal mounting hole 13 and the distal mounting hole 14. Figure 5 and Figure 7 After the first side key 2 is inserted into the mounting slot, the proximal end 21 is mounted in the proximal mounting hole 13. Figure 6 and combined Figure 5 , Figure 9 and combined Figure 8 as well as Figure 11 and Figure 10 The distal end 22 is mounted in the distal mounting hole 14 by the latch 4. The proximal end 21 and the distal end 22 are mounted in any manner as long as the first side key 2 does not fall out of the middle frame 1. The second side key 3 is mounted on the second mounting portion 12.

[0034] In some related technologies, because other components (for example, antennas, etc.) are also provided on the middle frame assembly, the distance between the first side key 2 and the second side key 3 is limited, resulting in the proximal mounting hole 13 being located in the connection area shown in F. If a hole is opened from the back of the middle frame 1, the second mounting portion 12, or the curved surface 19, will inevitably be damaged, and thus the appearance of the middle frame 1 is not beautiful. However, with the above arrangement, since the proximal mounting hole 13 corresponds to the area where the first mounting portion 11 and the second mounting portion 12 are connected, it also extends from the front of the middle frame 1 to the inside of the middle frame 1, and its depth is less than the thickness of the middle frame 1. Therefore, the proximal mounting hole 13 is opened from the front and does not penetrate the middle frame 1 (the proximal mounting hole 13 is opened from the front). Figure 1 、 Figure 2 、 Figure 5 and Figure 7 and with Figure 8 and Figure 10 As can be seen from the comparison, the proximal mounting hole 13 does not penetrate the middle frame 1, thus avoiding damage to the second mounting portion 12 or the curved surface 19. This ensures the aesthetic appearance of the middle frame 1, given its narrow, thin frame and the curved battery cover. Furthermore, the first side button 2 is lateral, so the direction of the mounting slot is perpendicular to the direction of the proximal mounting hole 13. This not only facilitates machining of the mounting slot and the proximal mounting hole 13, but also makes it easier to verify that the first side button 2 is properly installed in the proximal mounting hole 13.

[0035] For the distal mounting hole 14, it can be formed by opening a hole on the back of the middle frame 1 or on the front of the middle frame 1. Figure 1 、 Figure 2 、 Figure 5 and Figure 6 The distal mounting hole 14 extends from the front surface of the middle frame 1 toward the interior of the middle frame 1 .

[0036] As described above, if the distal mounting hole 14 is opened from the back of the middle frame 1 and the proximal mounting hole 13 is opened from the front of the middle frame 1, the distal mounting hole 14 and the proximal mounting hole 13 will be distributed on the front and back of the middle frame 1. During the processing, different clamping positions are required, and the relative position accuracy of the proximal mounting hole 13 and the distal mounting hole 14 cannot be guaranteed, and the appearance of the first side key 2 will have an uneven appearance. However, the distal mounting hole 14 and the proximal mounting hole 13 of the present application are both formed by opening from the front of the middle frame 1, and do not require different clamping positions. Therefore, the relative position accuracy of the proximal mounting hole 13 and the distal mounting hole 14 is ensured, and the appearance of the first side key 2 is highly consistent.

[0037] See also Figure 1 and combined Figure 2 、 Figure 6 and combined Figure 5 as well as Figure 11 and combined Figure 10 The distal mounting hole 14 extends toward the interior of the middle frame 1 and penetrates the middle frame 1 , and the latch 4 is installed into the distal mounting hole from the back of the middle frame 1 and plugged into the distal end 22 of the first side button 2 .

[0038] In some related designs, the latch 4 is installed into the distal mounting hole 14 from the front of the middle frame 1. This requires the main screen to be removed when the latch 4 is removed, thus rendering the main screen useless. In the above arrangement, the distal mounting hole 14 passes through the middle frame 1, and the latch 4 is installed into the distal mounting hole 14 from the back of the middle frame 1 and plugged into the distal end 22. Compared to installing the latch 4 into the distal mounting hole 14 from the front of the middle frame 1, the main screen does not need to be removed when the latch 4 is removed, thus preventing the main screen from being useless.

[0039] See also Figure 11 and combined Figure 10 , the middle frame 1 is provided with a limiting portion 141. Figure 2 and combined Figure 1 、 Figure 6 and combined Figure 5 、 Figure 9 and combined Figure 8 as well as Figure 11 and combined Figure 10 The latch 4 includes a contact portion 41 and an inserting portion 42. When the contact portion 41 is assembled with the limiting portion 141, the inserting portion 42 is inserted into the distal end 22 of the first side button 2.

[0040] As set up above, the distal mounting hole 14, whether it is opened from the front or from the back, extends along the thickness direction of the middle frame 1 (which can be understood as the Z direction of the terminal device, for example, the direction perpendicular to the screen), and the contact portion 41 contacts the limiting portion 141 to limit the pin 4 in the Z direction, ensuring that the plug-in portion 42 and the distal end 22 are reliably and accurately plugged in.

[0041] Based on the above-mentioned function of the limiting portion 141 , the structure and location of the limiting portion 141 are not limited, as long as the above-mentioned function can be achieved.

[0042] See also Figure 11 Combined with Figure 10 The middle frame 1 includes a limiting groove 15 connected to the distal mounting hole 14. The bottom wall of the limiting groove 15 and the inner wall of the distal mounting hole 14 form a step. The limiting portion 141 includes the step. The contact portion 41 is located on the step to achieve the assembly.

[0043] As described above, the limiting groove 15 is connected to the distal mounting hole 14, and the bottom wall of the limiting groove 15 and the inner wall of the distal mounting hole 14 form a step. The limiting portion 141 includes the step. In this way, the limiting portion 141 is simple in structure (for example, the limiting groove 15 and the distal mounting hole 14 can be formed together), and it is also easier to position the pin 4.

[0044] See also Figure 11 、 Figure 9 and Figure 6 The limiting groove 15 includes a groove wall 151 perpendicularly connected to the bottom wall, and the two ends of the groove wall 151 include limiting walls 152. Along the length direction of the first side key 2, the limiting walls 152 limit the corresponding ends of the contact portion 41. In other words, the limiting wall 152 located at the left end of the limiting groove 15 limits the left end of the contact portion 41, and the limiting wall 152 located at the right end of the limiting groove 15 limits the right end of the contact portion 41.

[0045] As set up above, the contact portion 41 is limited by two limiting walls 152 (also limited along the length direction of the first side key 2), combined with the limiting portion 141 limiting the contact portion 41 in the Z direction, so that the insertion accuracy between the pin 4 and the distal end 22 can be better ensured.

[0046] See also Figure 2 and Figure 11 The distal mounting hole 14 includes a distal hole wall 142 facing away from the outer side of the middle frame 1. Figure 11 , an insertion space 143 is formed between the distal end 22 and the distal end hole wall 142. Figure 6 and Figure 9 Combined with Figure 2 and Figure 11 The plug 4 includes an inserting portion 42 , and the inserting portion 42 is inserted into the inserting space 143 .

[0047] See also Figure 7 and Figure 2 The proximal mounting hole 13 includes a proximal hole wall 131 opposite to the outer side of the middle frame 1 , and the proximal end 21 abuts against the proximal hole wall 131 .

[0048] As described above, when installing the first side key 2, first insert the proximal end 21 into the proximal mounting hole 13 and Figure 1 Rotate in the direction indicated by the arrow R until the distal end 22 is located in the distal mounting hole 14 and forms the insertion space 143 with the distal hole wall 142. Then, insert the pin 4 into the insertion space 143 along the depth direction of the middle frame 1. As a result, the installation of the first side key 2 is convenient and simple, and a pin 4 can be omitted.

[0049] In some embodiments, the midframe assembly includes a battery cover (not shown). The battery cover has a curved edge. The shape of the battery cover edge complements the shape of the first mounting portion 11 and the shape of the second mounting portion 12. Thus, when the battery cover is assembled with the midframe 1, the edge of the battery cover engages with the first mounting portion 11 and the second mounting portion 12.

[0050] As described above, the first side key 2 and the second side key 3 can be installed while the middle frame 1 has an aesthetically pleasing appearance while the edge of the battery cover is curved and the frame is narrow.

[0051] In some embodiments, the first side key 2 is a volume key. The second side key 3 is a key that integrates fingerprint and power functions. In other embodiments, the second side key 3 is a fingerprint key or a power key. In this case, the first side key 2 may not be a volume key. Similarly, if the first side key 2 is a volume key, the second side key 3 may not be a key that integrates fingerprint and power functions.

[0052] In a second aspect, embodiments of the present application disclose a terminal device. The terminal device includes any of the aforementioned midframe assemblies. The terminal device can be a mobile phone, a laptop computer, a tablet computer, a learning machine, or other intelligent communication device.

[0053] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application shall be included in the scope of protection of this application.
