Detailed Description

The following are preferred embodiments of the present application and it should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of the present application, and these improvements and modifications should be considered as the protection scope of the present application.

Before the technical solutions of the present application are introduced, the technical problems in the related art will be described in detail.

Currently, electronic devices are usually provided with side keys on the sides thereof, so that users can touch or press the side keys, and control operations on the electronic devices are realized. For example, pressing the side key may lock the screen and wake the screen up. Or may increase and decrease the volume. In the related art, the side key is usually installed on the extending portion of the middle frame, that is, a first groove is formed on one side of the extending portion, which is away from the body, and the side key is installed in the first groove. But this requires the side keys to be fixed to prevent the side keys from falling. Therefore, at present, a hole is usually formed in the extending portion, and the side key fixing bracket is inserted into the first groove from the hole, so as to fix the side key.

However, since the through hole is formed on the surface of the extending portion and the battery cover is adhered to the surface in the following step, the adhesive layer cannot be adhered to the opening, so that the length of the opening on the surface is increased and the waterproof sealing width is reduced. Water entering the first groove from the side key is easier to enter the electronic equipment from the space between the middle frame and the battery cover, and the sealing and waterproof performance of the electronic equipment is reduced. In addition, some have filled seals into the hole in an attempt to plug the hole. But the surface of the sealing part can not be completely flush with the surface of the extending part provided with the hole. When the surface of the sealing part is lower than the surface provided with the holes, the bonding layer can not be adhered to the positions of the holes. When the surface of the sealing part is higher than the surface provided with the hole, the problem of top printing of the battery cover occurs, and the above technical problem cannot be effectively solved.

In view of this, the present application provides an electronic device and an assembling method thereof, in which a positioning assembly is directly installed from an opening of a first groove, so as to avoid an additional hole on an extension portion, thereby increasing a waterproof sealing width of a middle frame and improving a sealing performance of the electronic device.

Referring to fig. 1 and fig. 2 together, fig. 1 is an exploded schematic view of an electronic device according to an embodiment of the present application. Fig. 2 is a schematic structural diagram of an electronic device according to an embodiment of the present application. The embodiment provides an electronic device 1, which specifically comprises a middle frame 10, side keys 20 and a positioning component 30. The middle frame 10 includes a body 11 and an extending portion 12 extending from the periphery of the body 11, wherein a first groove 13 is formed on one side of the extending portion 12 away from the body 11, and a second groove 14 is formed on the side wall of the first groove 13. The side key 20 includes a side key body 21 and a positioning portion 22 disposed on one side of the side key body 21, and the positioning portion 22 is provided with a first through hole 23 corresponding to an opening of the second groove 14. The positioning assembly 30 includes a positioning member 31 and an elastic member 32 connected to the positioning member 31, the positioning member 31 includes a first portion 311 and a second portion 312, the first portion 311 is disposed in the second recess 14, and the second portion 312 is disposed in the first through hole 23 to limit the side key 20 from moving in a direction away from the middle frame 10.

The positioning assembly 30 includes a positioning member 31 and an elastic member 32, wherein the elastic member 32 is connected to the positioning member 31. The positioning member 31 includes a first portion 311 and a second portion 312, the first portion 311 is disposed in the second recess 14, the second portion 312 is disposed in the first through hole 23, and the positioning member 31 is used for limiting the side key 20 to move in a direction away from the middle frame 10.

The electronic device 1 provided by the present application includes, but is not limited to, a mobile terminal such as a mobile phone, a tablet Computer, a notebook Computer, a palmtop Computer, a Personal Computer (PC), a Personal Digital Assistant (PDA), a Portable Media Player (PMP), a navigation device, a wearable device, a smart band, a pedometer, and a fixed terminal such as a Digital TV, a desktop Computer, and the like.

The main body 11 is used for bearing structural components such as a main circuit board, a battery and the like; one side of the extension portion 12 is used for installing a display screen, the other side is used for bonding a battery cover through an adhesive layer, and in the related art, a hole is additionally formed on the other side of the extension portion 12 for installing a side key 20 fixing bracket. In the present application, a first groove 13 is formed on one side of the extension portion 12 departing from the body 11. Therefore, the extension portion 12 includes a first bottom wall 131 forming the first groove 13, and a first side wall 132 extending from the periphery of the first bottom wall 131. The present application provides a second groove 14 on the sidewall (i.e. the first sidewall 132) of the extension portion 12 forming the first groove 13. Similarly, the extension portion 12 forms a bottom wall of the first groove 13, i.e., a first bottom wall 131. The present application is described below with the first bottom wall 131 and the first side wall 132 being replaced.

The side key 20 provided by the present application includes a side key body 21 and a positioning portion 22, wherein the side key body 21 is exposed on an appearance surface of the electronic device 1 for a user to press and touch. The positioning part 22 is connected with the side key body 21 and arranged in the first groove 13, and the positioning part 22 is used for connecting the part 213 of the positioning piece 31. In addition, the opening of the first through hole 23 opened on the positioning portion 22 is arranged corresponding to the opening of the second groove 14. The corresponding arrangement mentioned here is to be understood as meaning that the opening of the first through-hole 23 at least partially overlaps the opening of the second through-hole. It is further understood that an orthographic projection of the opening of the first through hole 23 on the side wall opening the second recess 14 at least partially overlaps within the second recess 14. This allows the first portion 311 of the positioning member 31 to be disposed in the second recess 14, and the second portion 312 to be disposed in the first through hole 23.

Optionally, please refer to fig. 1 again. The first sidewall 132 includes a first sub-sidewall 1321 and a second sub-sidewall 1322 connected to each other, the second groove 14 is formed on the first sub-sidewall 1321, the first sub-sidewall 1321 is perpendicular to the body 11, and the second sub-sidewall 1322 is parallel to the body 11. The first sidewall 132 of the present application includes a first sub-sidewall 1321 and a second sub-sidewall 1322 connected to each other, and the second groove 14 is opened on the first sub-sidewall 1321. In addition, the first sub-sidewall 1321 of the present application is disposed perpendicular to the body 11, and the second sub-sidewall 1322 is disposed parallel to the body 11. Since the extension portion 12 of the present electronic apparatus 1 is substantially rectangular, and the second sub-sidewall 1322 is in the extending direction of the extension portion 12. Therefore, the second groove 14 is formed in the first sub-sidewall 1321, so that the side key 20, the second groove 14 and the positioning component 30 can be easily designed and installed in size, the structure is simplified, and the assembly difficulty is reduced.

The positioning assembly 30 provided by the present application includes a positioning member 31 and an elastic member 32, wherein the elastic member 32 is connected to the positioning member 31, that is, one end of the elastic member 32 is connected to the positioning member 31, but there are many cases in the present application with respect to the other end of the elastic member 32, and therefore, the details will be described later. The elastic member 32 is used for driving the positioning member 31 to move under the action of the elastic force, so that the first portion 311 is disposed in the second recess 14, and the second portion 312 is disposed in the first through hole 23. Alternatively, the elastic member 32 may be a spring, a steel plate having elastic deformation, elastic plastic, or the like.

Therefore, as can be seen from the above, the positioning assembly 30 of the present application can be directly installed from the opening of the first groove 13, and the positioning element 31 can move in the direction perpendicular to the first sub-sidewall 1321, so that it is not necessary to additionally provide a through hole on the extension portion 12, thereby increasing the waterproof sealing width of the middle frame 10 and improving the sealing performance of the electronic device 1. In addition, by additionally providing the positioning assembly 30, the positioning assembly 30 includes an elastic member 32 and a positioning member 31, the elastic member 32 is utilized to control the movement of the positioning member 31, and finally the first portion 311 of the positioning member 31 is disposed in the second recess 14, and the second portion 312 is disposed in the first through hole 23. Therefore, the positioning member 31 can limit the side key 20 from moving in the direction away from the middle frame 10, and prevent the side key 20 from falling off, thereby improving the connection performance of the side key 20.

In addition, the electronic equipment 1 increases the waterproof sealing width from 1.22 to 3.32, reduces the opening length from 6.2 to 0, increases the adhesive area of the back adhesive of the middle frame 10, and enhances the sealing performance and the adhesive strength of the whole machine. In addition, the elastic part 32 is used for pushing the positioning part 31 and the outer side key 20 limiting mode for limiting the second groove 14 of the middle frame 10, two side key 20 fixing supports in the related art are replaced, the material cost of the side key 20 fixing supports and the assembly cost of the side keys 20 are reduced, and the problem of battery cap top printing is also prevented.

As can be seen from the above, one end of the elastic member 32 is connected to the positioning member 31, but the other end has various connection positions. For example, the other end of the elastic element 32 can be connected to the side key body 21 or fixed in the second groove 14. Optionally, referring to fig. 2 again, in this embodiment, one end of the elastic element 32 is connected to the positioning element 31, and the other end of the elastic element 32 is connected to the side key body 21. This allows the positioning member 31 to move from the first through hole 23 toward the second recess 14 by the elastic member 32. It can also be understood that, in the present application, one end of the elastic element 32 may be connected to the side key body 21, the positioning element 31 may pass through the first through hole 23, and then the positioning element 31 may move towards the second groove 14 by the elastic force of the elastic element 32. As to the specific assembly method, the present application will be described in detail later. And the elastic piece 32 is connected to the side key body 21, so that the assembly difficulty of the positioning assembly 30 can be reduced, and the elastic piece 32 is easier to install.

Please refer to fig. 3, and fig. 3 is a schematic structural diagram of an electronic device according to another embodiment of the present application. The electronic device 1 shown in fig. 3 is substantially the same as the electronic device 1 shown in fig. 2, except that in this embodiment, one side of the positioning member 31 away from the elastic member 32 abuts against the extending portion 12 to form a bottom wall of the second groove 14, so as to limit the movement of the positioning member 31 in a direction close to the second groove 14.

The extension portion 12 further includes a second bottom wall 141 forming the second groove 14, and a second side wall 142 extending from the periphery of the second bottom wall 141. I.e. the bottom wall of the extension 12 forming the second recess 14, can be understood as a second bottom wall 141. Alternatively, the sidewall of the extension 12 forming the second groove 14 may be understood as the second sidewall 142. Therefore, the present application will be described below with reference to the second bottom wall 141 and the second side wall 142 instead.

In order to fix the side key 20 well, the positioning member 31 can be fixed to prevent the positioning member 31 from moving in a direction perpendicular to the second bottom wall 141, so that the positioning member 31 is only disposed in the first through hole 23, and the fixed side key 20 falls out again. Therefore, the side of the positioning element 31 departing from the elastic element 32 abuts against the second bottom wall 141, so that the elastic element 32 can limit the positioning element 31 from moving in the direction away from the second groove 14 without the external force. The second bottom wall 141 can limit the positioning element 31 from moving in a direction close to the second groove 14, so as to better limit the positioning element 31 from moving in a direction perpendicular to the second bottom wall 141, and improve the connection performance of the second positioning element 31.

Optionally, the resilient member 32 is in a compressed state. When one side of the positioning element 31 departing from the elastic element 32 abuts against the second bottom wall 141, the elastic element 32 is in a compressed state, and at this time, the positioning element 31 receives a force in a direction approaching to the second bottom wall 141, so that the positioning element 31 moves towards the second bottom wall 141. But the positioning member 31 is now abutting against the second bottom wall 141, better limiting the movement of the positioning member 31 in the direction perpendicular to the second bottom wall 141. Thus, the elastic member 32 is compressed to further improve the coupling performance of the positioning member 31.

Please refer to fig. 4, and fig. 4 is a schematic structural diagram of an electronic device according to another embodiment of the present application. The electronic device 1 shown in fig. 4 is substantially the same as the electronic device 1 shown in fig. 2, except that in this embodiment, a first locking portion 33 is disposed at an end of the positioning member 31 away from the elastic member 32, and a second locking portion 34 connected to the first locking portion 33 is disposed in the second groove 14 to limit the movement of the positioning member 31 in a direction away from the second groove 14.

As can be seen from the above, in an embodiment of the present application, a side of the positioning element 31 away from the elastic element 32 abuts against the second bottom wall 141, so as to better limit the movement of the positioning element 31 in a direction perpendicular to the second bottom wall 141. In another embodiment of the present application, the above object can be achieved by a snap connection of the snap portion. For example, a first locking portion 33 is disposed at an end of the positioning member 31 away from the elastic member 32, and a second locking portion 34 is disposed in the second recess 14. And the first latch portion 33 is in latch connection with the second latch portion 34, so as to limit the positioning member 31 from moving in a direction away from the second recess 14. This can reduce the length of the positioning member 31, thereby making it easier to assemble the positioning member 31.

Please refer to fig. 5, and fig. 5 is a schematic structural diagram of an electronic device according to another embodiment of the present application. The electronic device 1 shown in fig. 5 is substantially the same as the electronic device 1 shown in fig. 4, except that in this embodiment, a third locking portion 35 is further disposed in the second groove 14, the first locking portion 33 is disposed between the second locking portion 34 and the third locking portion 35, and the first locking portion 33 abuts against the second locking portion 34 and the third locking portion 35, respectively.

In the present application, a third fastening portion 35 may be further added, and the first fastening portion 33 is disposed between the second fastening portion 34 and the third fastening portion 35, and the first fastening portion 33 is respectively abutted to the second fastening portion 34 and the third fastening portion 35. In this way, the second locking portion 34 can limit the positioning member 31 from moving in a direction away from the second recess 14. And the third latching portion 35 can limit the positioning member 31 from moving in a direction approaching the second groove 14. The second buckling part 34 is matched with the third buckling part 35, so that the movement of the positioning piece 31 in the direction departing from the second bottom wall 141 is limited, and the connection performance of the positioning piece 31 is improved.

Please refer to fig. 6, and fig. 6 is a schematic structural diagram of an electronic device according to another embodiment of the present application. The electronic device 1 provided in fig. 6 of the present application is substantially the same as the electronic device 1 provided in fig. 2 of the present application, except that in this embodiment, the opening size of the second groove 14 close to the side key body 21 is larger than the opening size of the second groove 14 far from the side key body 21.

The positioning member 31 of the present application needs to enter the second recess 14 from the direction of the first through hole 23. Therefore, the present application can make the opening size of the second groove 14 close to the side key body 21 larger than the opening size of the second groove 14 far from the side key body 21, and can also understand that the second groove 14 includes a first end 143 and a second end 144 oppositely disposed, wherein the first end 143 is close to the side key body 21, and the second end 144 is far away from the side key body 21. And the opening size of first end 143 is larger than the opening size of second end 144. This makes the side of the second recess 14 close to the side key body 21 open more, which allows the positioning member 31 to enter the second recess 14 better.

Please refer to fig. 7, and fig. 7 is a schematic structural diagram of an electronic device according to another embodiment of the present application. The electronic device 1 shown in fig. 7 is substantially the same as the electronic device 1 shown in fig. 6, except that in this embodiment, a surface of the positioning member 31 on a side away from the elastic member 32 is arc-shaped.
