Description

Technical Field

[0001] The present invention relates to the technical field of electronic products, and in particular to a mounting assembly for a middle frame and an electronic device. Background Art

[0002] With the development of electronic technology, the requirements for electronic products such as mobile phones, tablets, and e-readers are getting higher and higher. Among them, waterproof performance has become the most basic requirement for electronic products. When assembling electronic products, since the method of assembling buttons from the inside out is not suitable for waterproof products, at present, the buttons are basically assembled from the outside in. According to the structure of the button, it can be divided into an integrated button (the button is a whole) and a split button (the split button usually includes a button and a mounting part for installing the button).

[0003] The integrated key is assembled by key + TPU glue dispensing bonding. This assembly method has the following defects: 1) It has high requirements for the amount of glue controlled and the storage of glue. Insufficient glue dispensing, use of expired glue or glue not set according to the specified parameters will lead to insufficient pull-out force and the risk of the key falling off; 2) During assembly, there is a situation where the key is stuck in the installation slot and cannot be completely reset, resulting in a poor feel; 3) The key shakes greatly.

[0004] Split-type keys are usually assembled by combining a hook on the key with a small steel sheet. This assembly method has the following defects: 1) The small steel sheet is fixed to the middle frame (metal material) by friction. The friction coefficient between the two metals is relatively small, resulting in the small steel sheet being unstable and easy to fall off; 2) The small steel sheet itself shakes, resulting in the key not being able to be locked well, causing the key to shake significantly. Summary of the invention

[0005] The main purpose of the embodiments of the present invention is to provide an installation component for a middle frame and an electronic device, which aims to solve technical problems such as unstable installation and easy shaking of buttons.

[0006] In a first aspect, an embodiment of the present invention provides an installation assembly for a middle frame, including:

[0007] A mounting member, a portion of which is accommodated in the accommodating groove of the middle frame and is used to install the button of the middle frame;

[0008] The elastic member is configured such that when the mounting member is accommodated in the accommodating groove, at least a portion of the elastic member is elastically squeezed between the mounting member and the groove side wall of the accommodating groove.

[0009] In a second aspect, an embodiment of the present invention further provides an electronic device, including:

[0010] A middle frame, wherein the middle frame has a mounting groove and a receiving groove, and the mounting groove and the receiving groove are connected;

[0011] A button, the button is movably mounted in the mounting slot, a portion of the button is accommodated in the mounting slot, and another portion of the button extends out of the mounting slot;

[0012] The mounting assembly is the above-mentioned mounting assembly, a part of which is accommodated in the accommodating groove, and another part extends into the mounting groove to abut against the button and is used to limit the button from moving toward the notch of the mounting groove.

[0013] The installation component and electronic device for the middle frame provided by the embodiment of the present invention are used to install the button of the middle frame by setting a mounting piece, that is, abutting against the button to prevent the button from falling off from the middle frame, and combined with the elastic force provided by the switch, the button is firmly installed and will not shake; by setting an elastic piece, when the mounting piece is accommodated in the accommodating groove, the elastic piece is elastically squeezed between the mounting piece and the groove side wall of the accommodating groove. On the one hand, the mounting piece is firmly accommodated in the accommodating groove, thereby avoiding the shaking of the button caused by the shaking of the mounting piece. On the other hand, since the elastic piece is elastically squeezed between the mounting piece and the groove side wall of the accommodating groove, it is not necessary to make the size of the accommodating groove strictly match the external contour of the mounting piece, thereby reducing the requirement on the size of the accommodating groove, that is, reducing the processing requirement on the size of the middle frame, and the tolerance capability is strong, the yield of the middle frame is greatly improved, and the cost is greatly reduced. On the other hand, due to the elasticity of the elastic piece, it is convenient to install the mounting component in the accommodating groove or take it out from the accommodating groove. Therefore, the installation assembly provided by the present invention can enable the key to be firmly installed in the middle frame without shaking, and at the same time, the processing requirements for the size of the middle frame are low, and the installation assembly is easy to disassemble and assemble.

[0034] When assembling buttons, both integrated buttons and split buttons have more or less defects, such as loose installation of buttons, shaking of buttons, etc. In view of this, the present invention provides an installation assembly for a middle frame and an electronic device, wherein the installation assembly can firmly assemble the buttons on the middle frame without shaking, and has low processing requirements on the size of the middle frame.

[0035] like Figures 1 to 7As shown, the electronic device provided by the embodiment of the present invention includes a middle frame 100, a button 200 and a mounting assembly 300; the middle frame 100 has a mounting groove 101 and a receiving groove 102, and the mounting groove 101 and the receiving groove 102 are connected; the button 200 can be movably mounted in the mounting groove 101, a part of the button 200 is received in the mounting groove 101, and the other part extends out of the mounting groove 101; a part of the mounting assembly 300 is received in the receiving groove 102, and the other part extends into the mounting groove 101 to abut against the button 200, and is used to limit the button 200 from moving in the direction of the notch of the mounting groove 101. In a specific application, one end of the button 200 away from the notch of the mounting groove 101 is connected to a switch of the electronic device, and the switch applies an elastic force to the button 200 in the direction of the notch of the mounting groove 101, so that the button 200 moves in the direction close to the notch of the mounting groove 101, and then abuts against the mounting assembly 300. When the button 200 abuts against the mounting assembly 300, the mounting assembly 300 generates resistance to the button 200 in the direction of the switch, and the button 200 is firmly installed in the mounting groove 101 under the action of the elastic force and the resistance. In addition, at least one end of the button 200 away from the switch extends out of the mounting groove 101 when the button 200 abuts against the mounting assembly 300, that is, the button 200 is protruded to facilitate pressing.

[0036] By adopting the above technical scheme, by setting the installation groove 101 and the receiving groove 102, the button 200 is movably installed in the installation groove 101, and the installation component 300 is installed in the receiving groove 102. By connecting the installation groove 101 and the receiving groove 102, when the button 200 moves toward the direction close to the notch of the installation groove 101 under the action of the switch, the button 200 can abut against the installation component 300, restricting the button 200 from moving toward the direction close to the notch of the installation groove 101, thereby preventing the button 200 from falling off from the installation groove 101, and under the joint action of the installation component 300 and the switch, the button 200 is subjected to the joint action of resistance and elastic force in opposite directions, and will not shake.

[0037] As an embodiment, the electronic device includes but is not limited to a mobile phone, a tablet computer, a laptop computer, and an e-reader.

[0038] Reference Figure 5 and Figure 8As shown, the installation assembly 300 provided in the embodiment of the present invention is used for the middle frame 100, and includes a mounting member 10 and an elastic member 20; a portion of the mounting member 10 is accommodated in the receiving groove 102 of the middle frame 100, and is used to install the button 200 of the middle frame 100; when the mounting member 10 is accommodated in the receiving groove 102, at least a portion of the elastic member 20 is elastically squeezed between the mounting member 10 and the groove side wall of the receiving groove 102. The mounting member 10 is provided to mount the button 200 of the middle frame 100, that is, the mounting member 10 abuts against the button 200 to prevent the button 200 from falling off from the middle frame 100, and combined with the elastic force provided by the switch, the button 200 is firmly installed without shaking; the elastic member 20 is provided, and when the mounting member 10 is accommodated in the accommodating groove 102, the elastic member 20 is elastically squeezed between the mounting member 10 and the groove side wall of the accommodating groove 102, on the one hand, the mounting member 10 is firmly accommodated in the accommodating groove 102, thereby preventing the mounting member 10 from shaking and causing the button 200 to fall off from the middle frame 100. On the other hand, since the elastic member 20 is elastically squeezed between the mounting member 10 and the groove side wall of the receiving groove 102, it is not necessary to make the size of the receiving groove 102 strictly match the outer contour of the mounting member 10, which reduces the requirements for the size of the receiving groove 102, that is, reduces the processing requirements for the size of the middle frame 100, has a strong tolerance capability, greatly improves the yield of the middle frame 100, and greatly reduces the cost. On the other hand, because of the elasticity of the elastic member 20, it is conducive to installing the installation component 300 in the receiving groove 102 or taking it out of the receiving groove 102. Therefore, the installation component 300 provided in the embodiment of the present invention can make the key 200 firmly installed in the middle frame 100 without shaking, and at the same time, the processing requirements for the size of the middle frame 100 are low, and the installation component 300 is easy to disassemble and assemble.

[0039] As an implementation method, refer to Figure 5 and Figure 8 As shown, the mounting member 10 includes a mounting body 11 and at least one first abutting portion 12 connected to the mounting body 11, and the first abutting portion 12 is used to abut against the button 200 of the middle frame 100; the elastic member 20 is connected to the mounting body 11, and when the mounting member 10 is accommodated in the accommodating groove 102, at least a part of the elastic member 20 is elastically squeezed between the mounting body 11 and the groove side wall of the accommodating groove 102. The structure is simple and easy to manufacture. Of course, in a specific application, as an alternative embodiment, it is also possible that the elastic member 20 is not connected to the mounting body 11; for example, the elastic member 20 is connected to the groove side wall of the accommodating groove 102, or the elastic member 20 is separately provided, and when the mounting member 10 is accommodated in the accommodating groove 102, the elastic member 20 is squeezed between the mounting member 10 and the groove side wall of the accommodating groove 102.

[0040] As an implementation method, refer to Figure 5 , Figure 7 , Fig. 9 and Fig.10 As shown, the installation body 11 is provided with a first side surface 111. When the installation member 10 is accommodated in the receiving groove 102, at least a portion of the elastic member 20 protrudes from or is flush with the first side surface 111 and is pressed against the groove side wall of the receiving groove 102. The first abutting portion 12 is provided with a second side surface 121. The second side surface 121 is used to abut against the button 200 of the middle frame 100. The first side surface 111 and the second side surface 121 are arranged on the same side. By arranging the second side surface 121 to abut against the button 200, at least a portion of the elastic member 20 protruding from or flush with the first side surface 111 is arranged to be elastically pressed against the groove side wall of the receiving groove 102, and the first side surface 111 and the second side surface 121 are arranged on the same side, so that the third side surface 112 of the installation body 11 described below abuts against another portion of the groove side wall of the receiving groove 102 when the installation member 10 is accommodated in the receiving groove 102. For ease of description, the groove side wall of the accommodating groove 102 elastically squeezed by at least part of the elastic member 20 protruding or flush with the first side surface 111 is defined as the first groove side wall 1021, and the groove side wall of the accommodating groove 102 pressed by the third side surface 112 is defined as the second groove side wall 1022. Regardless of whether the button 200 abuts against the first abutting portion 12, the third side surface 112 of the mounting body 11 abuts against the second groove side wall 1022, and the mounting member 10 is firmly installed, which is not affected by whether the button 200 abuts, forming a unilateral interference mode, and is less affected by other factors. Among them, the second groove side wall 1022 is arranged relative to the first groove side wall 1021 at a distance. In specific applications, the elastic member 20 can be set to a unilateral interference of 0.05mm to 0.1mm, so that the elastic member 20 can be prevented from loosening and the mounting assembly 300 can be prevented from being difficult to install in the accommodating groove 102.

[0041] As an implementation method, refer to Figure 5 , Figure 7 and Fig. 9 As shown, the elastic member 20 has an inclined surface 21; the inclined surface 21 extends obliquely from the top of the mounting member 10 to the bottom of the mounting member 10 in a trend of gradually approaching the first side surface 111. Specifically, at least the elastic member 20 located at the top of the mounting member 10 is elastically pressed against the first groove side wall 1021. Such a configuration facilitates the insertion of the mounting assembly 300 into the receiving groove 102, and reduces the dimensional requirements for the processing accuracy of the receiving groove 102 and the mold forming accuracy of the mounting assembly 300. The top of the mounting member 10 refers to the end corresponding to the notch of the receiving groove 102 when the mounting member 10 is accommodated in the receiving groove 102, and the bottom of the mounting member 10 refers to the end corresponding to the bottom wall of the receiving groove 102 when the mounting member 10 is accommodated in the receiving groove 102. Of course, in a specific application, as an alternative embodiment, it is also possible that the elastic member 20 is not provided with the inclined surface 21.

In this way, in the assembly process, the elastic member 20 can be directly sleeved on the outer periphery of the mounting body 11 along the height direction of the mounting member 10, and the assembly is convenient and quick. Of course, in a specific application, as an alternative embodiment, the elastic member 20 is not set to be annular, and it is also possible to set it to be strip-shaped or block-shaped, etc. When this solution is adopted, the elastic member 20 can be installed on the first side surface 111. Among them, the height direction of the mounting member 10 is the direction from the bottom to the top of the mounting member 10.

[0043] As an implementation method, refer to Figure 8 As shown, the mounting body 11 is provided with an annular groove 13 along the height direction, and the elastic member 20 is accommodated in the annular groove 13.
