Mounting components and electronic devices for midframes

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure is based on Chinese patent application CN202310830850.3 filed on July 6, 2023, entitled “Installation assembly and electronic device for middle frame”, and claims the priority of the patent application, and all the contents disclosed therein are incorporated into this disclosure by reference. Technical Field

[0003] The present disclosure 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

[0004] With the advancement of electronic technology, the requirements for electronic products such as mobile phones, tablets, and e-readers are becoming increasingly stringent. Waterproofing has become a fundamental requirement for these products. Since assembling buttons from the inside out is not suitable for waterproof products, the current method of assembling buttons from the outside in is generally used. Keyboards can be categorized by their structure as either one-piece buttons (which are a single unit) or split buttons (which typically consist of both the button and mounting hardware).

[0005] The integrated key is assembled using a key + TPU glue dispensing method. This assembly method has the following defects: 1) It has high requirements for the amount of glue used 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 pulling 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.

[0006] Split keys are usually assembled by combining a hook on the key and 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.

[0035] When assembling buttons, both integrated and split buttons have varying degrees of defects, such as loose or wobbly installation. In light of this, the present disclosure provides a mounting assembly for a midframe and an electronic device. The mounting assembly securely mounts buttons to the midframe without wobbling, while also minimizing the processing requirements for the midframe dimensions.

[0036] As shown in Figures 1 to 7, the electronic device provided by the embodiment of the present disclosure 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 is movably mounted in the mounting groove 101, with a portion of the button 200 received in the mounting groove 101 and another portion extending out of the mounting groove 101; a portion of the mounting assembly 300 is received in the receiving groove 102, and another portion extends into the mounting groove 101 to abut against the button 200, and is used to limit the movement of the button 200 toward the notch of the mounting groove 101. In a specific application, the 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 toward the notch of the mounting groove 101, thereby causing the button 200 to move toward the notch of the mounting groove 101 and then abut against the mounting assembly 300. When the button 200 abuts the mounting assembly 300, the mounting assembly 300 generates resistance against the button 200 in the direction of the switch. Due to the elastic force and resistance, the button 200 is securely mounted in the mounting slot 101. Furthermore, at least the end of the button 200 away from the switch protrudes out of the mounting slot 101 when the button 200 abuts the mounting assembly 300, i.e., the button 200 is protruding, facilitating pressing.

[0037] By adopting the above technical solution, 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, limiting the movement of the button 200 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.

[0038] 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.

[0039] 5 and 8 , an installation assembly 300 provided in an embodiment of the present disclosure is used for a middle frame 100 and includes a mounting member 10 and an elastic member 20 . A portion of the mounting member 10 is accommodated in a receiving groove 102 of the middle frame 100 and is used to install a 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 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 mounted 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 elastically squeezes between the mounting member 10 and the groove side wall of the accommodating groove 102, on the one hand, so that 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. This causes the key 200 to wobble. On the other hand, because the elastic member 20 elastically squeezes between the mounting member 10 and the sidewalls of the receiving groove 102, it is not necessary to strictly match the dimensions of the receiving groove 102 with the outer contour of the mounting member 10. This reduces the requirements for the dimensions of the receiving groove 102, that is, reduces the processing requirements for the dimensions of the middle frame 100, improves the tolerance capability, greatly improves the yield of the middle frame 100, and significantly reduces the cost. On the other hand, the elasticity of the elastic member 20 facilitates the installation of the mounting assembly 300 in the receiving groove 102 or its removal from the receiving groove 102. Therefore, the mounting assembly 300 provided in the embodiment of the present disclosure can firmly install the key 200 in the middle frame 100 without shaking, while having low processing requirements for the dimensions of the middle frame 100 and facilitating the assembly and disassembly of the mounting assembly 300.

[0040] As one embodiment, as shown in Figures 5 and 8 , the mounting member 10 includes a mounting body 11 and at least one first abutting portion 12 connected to the mounting body 11. The first abutting portion 12 is configured to abut against the button 200 of the middle frame 100. An elastic member 20 is connected to the mounting body 11. When the mounting member 10 is received in the receiving groove 102, at least a portion of the elastic member 20 is elastically compressed between the mounting body 11 and the sidewalls of the receiving groove 102. This structure is simple and easy to manufacture. Of course, in specific applications, as an alternative embodiment, the elastic member 20 may not be connected to the mounting body 11. For example, the elastic member 20 may be connected to the sidewalls of the receiving groove 102, or the elastic member 20 may be provided separately. When the mounting member 10 is received in the receiving groove 102, the elastic member 20 is compressed between the mounting member 10 and the sidewalls of the receiving groove 102.

[0041] As one embodiment, as shown in Figures 5, 7, 9, and 10, the mounting body 11 has a first side surface 111. When the mounting 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 sidewall of the receiving groove 102. The first abutting portion 12 has a second side surface 121, which is configured to abut against the button 200 of the middle frame 100. The first side surface 111 and the second side surface 121 are disposed on the same side. By arranging the second side surface 121 to abut against the button 200, at least the portion of the elastic member 20 that protrudes from or is flush with the first side surface 111 is configured to elastically press against the sidewall of the receiving groove 102. The first side surface 111 and the second side surface 121 are disposed on the same side. This allows the third side surface 112 of the mounting body 11, described below, to abut against another portion of the sidewall of the receiving groove 102 when the mounting member 10 is accommodated in the receiving groove 102. For ease of description, the sidewall of the accommodating groove 102 elastically squeezed by at least the portion of the elastic member 20 that protrudes or is flush with the first side surface 111 is defined as the first sidewall 1021, and the sidewall of the accommodating groove 102 against which the third side surface 112 abuts is defined as the second sidewall 1022. Regardless of whether the button 200 abuts the first abutting portion 12, the third side surface 112 of the mounting body 11 abuts the second sidewall 1022. The mounting member 10 is securely installed and is not affected by whether the button 200 abuts, forming a unilateral interference arrangement that is less affected by other factors. The second sidewall 1022 is spaced apart from the first sidewall 1021 and disposed in opposition. In specific applications, the elastic member 20 can be configured to have a unilateral interference of 0.05 mm to 0.1 mm. This prevents the elastic member 20 from loosening and prevents the mounting assembly 300 from being difficult to install in the accommodating groove 102.

[0042] As one embodiment, as shown in Figures 5, 7, and 9, the elastic member 20 has an inclined surface 21. The inclined surface 21 extends from the top of the mounting member 10 to the bottom of the mounting member 10, gradually approaching the first side surface 111. Specifically, at least the elastic member 20 at the top of the mounting member 10 elastically presses against the first groove sidewall 1021. This arrangement facilitates insertion of the mounting assembly 300 into the receiving groove 102 and reduces the dimensional requirements for the machining 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 of the mounting member 10 corresponding to the notch of the receiving groove 102 when the mounting member 10 is received in the receiving groove 102, and the bottom of the mounting member 10 refers to the end of the mounting member 10 corresponding to the bottom wall of the receiving groove 102 when the mounting member 10 is received in the receiving groove 102. Of course, in specific applications, as an alternative embodiment, the elastic member 20 can also be provided without the inclined surface 21.

[0043] In one embodiment, the elastic member 20 is annular and is mounted on the outer periphery of the mounting body 11 along the height direction of the mounting member 10, with at least a portion of the elastic member 20 protruding from the first side surface 111. With this arrangement, during the assembly process, the elastic member 20 can be directly mounted on the outer periphery of the mounting body 11 along the height direction of the mounting member 10, making assembly convenient and quick. Of course, in specific applications, as an alternative embodiment, the elastic member 20 may not be configured as an annular shape, such as a strip or block shape. In this case, the elastic member 20 may be mounted on the first side surface 111. The height direction of the mounting member 10 is the direction from the bottom to the top of the mounting member 10.

[0044] As one embodiment, as shown in FIG8 , the mounting body 11 is provided with an annular groove 13 along its height, and the elastic member 20 is accommodated within the annular groove 13. This improves the stability of the elastic member 20 assembled on the mounting member 10. It is understood that in other embodiments, the mounting body 11 may not be provided with the annular groove 13, and the elastic member 20 may be directly mounted on the outer surface of the mounting body 11.

[0045] As one embodiment, referring to Figures 7, 9, and 11, the mounting body 11 further includes a third side surface 112 disposed opposite the first side surface 111. The annular groove 13 includes a first groove body 131 and a second groove body 132. The groove opening of the first groove body 131 is located on the first side surface 111, and the groove opening of the second groove body 132 is located on the third side surface 112. The cross-sectional diameter of the elastic member 20 is greater than the groove depth of the first groove body 131 and less than or equal to the groove depth of the second groove body 132. This configuration allows a portion of the elastic member 20 to protrude from the first side surface 111. When the mounting assembly 300 is accommodated in the accommodating groove 102, the elastic member 20 can elastically press against the first groove sidewall 1021, and the second side portion of the mounting body 11 can abut against the second groove sidewall 1022.

[0046] In one embodiment, the depth of the first groove 131 gradually increases from the top to the bottom of the mounting member 10. This configuration allows the elastic member 20, when accommodated within the annular groove 13, to form an inclined surface 21 within the first groove 131. Of course, in specific applications, as an alternative embodiment, the depth of the first groove 131 can be maintained constant from the top to the bottom of the mounting member 10, and the inclined surface 21 can also be provided directly on the elastic member 20.

[0047] As an embodiment, the mounting member 10 includes two first abutment portions 12 connected to opposite sides of the mounting body 11, forming a symmetrical structure. This arrangement facilitates installation and manufacture of the mounting member 10 while also improving its versatility. Specifically, the mounting member 10 can be symmetrically arranged with the portion corresponding to the annular groove 13 as its central axis. Of course, in specific applications, as an alternative embodiment, the mounting member 10 can also include a single first abutment portion 12.

[0048] In one embodiment, the mounting member 10 is made of a hard rubber material, and the elastic member 20 is made of a soft rubber material. The mounting member 10 is made of a hard rubber material to ensure sufficient strength to abut against the button 200; the elastic member 20 is made of a soft rubber material to ensure elasticity.

[0049] In one embodiment, the hard plastic material includes at least one of acrylonitrile butadiene styrene (ABS) and polycarbonate (PC); the soft plastic material includes at least one of hydrogenated cyanobutyl rubber, nitrile butadiene rubber, silicone rubber, fluorinated rubber, fluorosilicone rubber, and butyl rubber. In specific applications, the color of the mounting member 10 and the elastic member 20 can be made to match the color of the middle frame 100 (both black), which can enhance the secondary appearance of the electronic device.

[0050] As an embodiment, the mounting assembly 300 is formed by integrally molding the elastic member 20 and the mounting member 10 through a liquid silicone injection molding process, which is quick to manufacture and saves time.

[0051] As an embodiment, as shown in FIG5 , there are two mounting assemblies 300 and two receiving slots 102 . The two receiving slots 102 are spaced apart along a first direction, and the mounting slot 101 is disposed between the two receiving slots 102 and communicates with both receiving slots 102 . The mounting assemblies 300 are disposed in a one-to-one correspondence with the receiving slots 102 . In this way, both sides of the key 200 along the first direction are mounted via the mounting assemblies 300 , making the key 200 more secure and less prone to shaking. The first direction is the length of the key 200 .

[0052] As an embodiment, the two receiving grooves 102 are symmetrically arranged on both sides of the installation groove 101, so that the two installation components 300 are symmetrically located on both sides of the button 200. Such an arrangement improves the stability of the installation of the button 200.

[0053] As an embodiment, referring to Figures 5, 8, and 12, the button 200 includes a pressing portion 201, two second abutting portions 202, and two connecting portions 203. The pressing portion 201 extends along a first direction, and the two second abutting portions 202 are spaced apart along the first direction. The two second abutting portions 202 are both located on a side of the pressing portion 201 that faces the bottom wall of the mounting groove 101. A connecting portion 203 is connected between each second abutting portion 202 and the pressing portion 201, and a first abutting portion 12 is provided between each second abutting portion 202 and the pressing portion 201. With this arrangement, the second abutting portions 202 abut against the first abutting portions 12, and when the second abutting portions 202 abut against the first abutting portions 12, the first abutting portions 12 exert resistance on the second abutting portions 202 in the switching direction.

[0054] In one embodiment, the notch of the mounting groove 101 is opened on the side of the middle frame 100, and the mounting groove 101 extends along the width direction or the length direction of the middle frame 100. Specifically, the side of the electronic device with a display screen is the front, the side opposite to the front is the rear, and the parts connecting the front and rear are all sides, where the sides can be divided into upper side, lower side, left side, and right side. When the notch of the mounting groove 101 is opened on the upper side or lower side of the middle frame 100, the mounting groove 101 extends along the width direction of the middle frame 100, and the above-mentioned first direction is the width direction of the middle frame 100; when the notch of the mounting groove 101 is opened on the left side or right side of the middle frame 100, the mounting groove 101 extends along the length direction of the middle frame 100, and the above-mentioned first direction is the length direction of the middle frame 100.

[0055] As an embodiment, the notch of the accommodating groove 102 is opened at the rear portion of the middle frame 100 , and the accommodating groove 102 extends along the thickness direction of the middle frame 100 .

[0056] The above description is only a preferred embodiment of the present disclosure and does not limit the patent scope of the present disclosure. All equivalent structural transformations made by using the contents of the present disclosure and the drawings under the inventive concept of the present disclosure, or direct / indirect application in other related technical fields are included in the patent protection scope of the present disclosure.
