Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a middle frame assembly and electronic equipment. Background Art

[0002] In today's mobile phone industry, in order to achieve better image quality, the size of cameras is getting bigger and bigger. At the same time, people want their mobile phones to be thin and light. Therefore, the Z-direction size of the camera has become the most critical reason for limiting the thickness of the entire phone.

[0003] At present, there are three main ways to limit the camera in the Z direction. The first is to use an integrated aluminum alloy to directly limit the camera. This solution is limited by the strength and flatness of the aluminum alloy, and often requires a thickness of 0.40mm. The maximum thickness is at least 0.30mm, which directly affects the thickness of the whole machine. The second is to use an external bracket to add to the camera, and the middle frame directly supports the camera bracket for Z-direction limiting. This solution can make a hole in the camera position of the middle frame, so it is the most economical way to save Z-direction thickness. However, this will add a camera bracket to the camera, which not only increases the manufacturing cost, but also occupies the effective area of ​​the motherboard and affects the motherboard layout. The third is to use the middle frame to make a hole at the camera position, and then spot weld a layer of stainless steel sheet on the back to support the camera with the stainless steel sheet. Because the thickness of the stainless steel sheet can usually be 0.20mm, it will save at least 0.10mm of the whole machine thickness compared to the first solution. However, since the middle frame is usually made of aluminum alloy, and the mutual welding reliability of stainless steel and aluminum alloy is relatively low, during the whole machine falling process, the stainless steel sheet is likely to be desoldered by force, which will cause the risk of screen cracking.

[0039] Reference Figures 1 to 5 As shown, a middle frame assembly provided in this embodiment includes: a middle frame 1, which is formed with a receiving space for accommodating a camera assembly 5, and the receiving space penetrates the middle frame 1 along the thickness direction Z of the middle frame 1; a limiter 2, wherein the limiter 2 can be a rigid material that is not easily deformed, such as stainless steel, and is covered at one end of the middle frame 1 along its thickness direction Z; wherein the limiter 2 is connected to the middle frame 1 through a fastener 3, and the fastener 3 can be a structure such as a bolt, a screw, a rivet column, etc.

[0040] The middle frame assembly provided in this embodiment connects the middle frame 1 and the limiter 2 with the fastener 3, which not only ensures that a stable and reliable camera support structure is formed on the middle frame 1 by utilizing the self rigidity of the limiter 2, but also the limiter 2 is connected to the middle frame 1 through the fastener 3, which can improve the connection strength between the limiter 2 and the middle frame 1, thereby further improving the connection stability and reliability between the camera assembly 5 and the middle frame 1; at the same time, the support of the limiter 2 can also be utilized to save the thickness of the middle frame 1 in the thickness direction Z, thereby reducing the influence of the camera assembly 5 on the thickness of the whole machine.

[0041] In some embodiments, the middle frame 1 includes a first surface 11 located at one end of the middle frame 1 in the thickness direction Z and a second surface 12 arranged opposite to the first surface 11. It should be understood that the first surface 11 refers to the end surface of the middle frame 1 away from the camera assembly 5; the first surface 11 is provided with a first sink 13, and the first sink 13 includes a bottom wall 131 and a side wall 132, the bottom wall 131 and the side wall 132 are connected, and the side wall 132 is arranged around the receiving space; the limiter 2 is received in the first sink 13 and abuts against the bottom wall 131, wherein the bottom wall 131 and the limiter The end face of the limiting member 2 on one side facing the camera assembly 5 is abutted against the limiting member 2; by setting the first recessed groove 13, the peripheral side and end face of the limiting member 2 can be limited, so that the limiting member 2 and the middle frame 1 can be pre-installed conveniently. That is to say, before the limiting member 2 and the middle frame 1 are fixedly connected by the fastener 3, the limiting member 2 can be placed in the first recessed groove 13 first, so that the limiting member 2 will not shake or deflect when connected to the middle frame 1 by the fastener 3, thereby improving the stability of the limiting member 2 on the middle frame 1 and improving the installation efficiency of the limiting member 2 on the middle frame 1.
