Illustratively, the first waterproof adhesive member 20 may include, but is not limited to, waterproof foam or other double-sided adhesive having waterproof properties. The substrate of the waterproof foam adhesive can include, but is not limited to, closed-cell foam of polyethylene or other substrates with waterproof performance. In the present embodiment, the structure of the first waterproof adhesive member 20 is not further limited.

As shown in fig. 6, the outer edge of the first waterproof adhesive member 20 extends toward the outside of the key assembly 10. Thus, the area of the first waterproof adhesive member 20 can be increased, and when the key assembly 10 is bonded in the key groove 212 through the first waterproof adhesive member 20, the distance between the edge of the first waterproof adhesive member 20 and the groove wall 2122 of the key groove 212 can be reduced, so that liquid entering the key groove 212 carelessly is far away from the insertion port 2121, the waterproof performance of the electronic device 200 at the key groove 212 is enhanced, and the bonding effect of the key assembly 10 in the key groove 212 can also be enhanced.

This enables the width of the first waterproof adhesive member 20 to be controlled within a certain range while achieving the assembly of the key assembly 10 in the key groove 212 and ensuring the waterproof performance of the electronic device 200 at the key groove 212, so as to save the assembly cost of the touch key unit 100 in the key groove 212.

In some embodiments, the outer edge of the first waterproof adhesive 20 may be flush with the edge of the adhesive surface 131, or the outer edge of the first waterproof adhesive 20 may protrude and be exposed outside the adhesive surface 131. Thus, the bonding area between the key assembly 10 and the casing 210 can be increased, the stability of the key assembly 10 during assembly can be increased, the liquid entering the key groove 212 can be prevented from entering the bonding surface 131 of the key assembly 10, the water resistance of the key assembly 10 on the bonding surface 131 can be realized, and the liquid in the key groove 212 can be kept away from the interface 2121 as far as possible, which is beneficial to further enhancing the waterproof performance of the electronic device 200 at the key groove 212.

In order to facilitate the interface member 132 to be inserted into the interface 2121, referring to fig. 6 and 8, the first waterproof adhesive member 20 has an avoiding hole 21 for the interface member 132 to pass through, and the avoiding hole 21 is disposed opposite to the interface member 132. Thus, on the basis that the key assembly 10 is assembled in the key groove 212 through the first waterproof adhesive member 20, the interface member 132 can be avoided through the avoiding hole 21, so that the interface member 132 can penetrate through the avoiding hole 21 and be arranged in the interface 2121 in a penetrating manner.

Referring to fig. 8, since key assembly 10 is provided with other functional modules on adhesive surface 131, the functional modules are located on one side of interface member 132. For avoiding the functional module to influence the bonding effect of key assembly 10 and casing 210, the trompil size of dodging hole 21 can be greater than the size of interface piece 132 to functional module can wear to establish in dodging hole 21, dodge the back through dodging hole 21 to functional module, can hold and establish in the heavy platform according to keyway 212, in order to ensure the bonding effect of key assembly 10 and casing 210.

FIG. 9 illustrates an exploded view of an assembly of a touch key unit from a first viewing angle.

The light touch key unit 100 is provided with a positioning hole matched with the positioning part 2123 in structure. The positioning holes are opposite to the positioning portions 2123 in number and correspond to one another. In the process that the light-touch key unit 100 is bonded to the housing 210 at the key groove 212 through the first waterproof adhesive member 20, the positioning portion 2123 may first penetrate through the positioning hole, so that the bonding of the light-touch key unit 100 in the key groove 212 can be positioned through the interaction between the positioning portion 2123 and the positioning hole, thereby improving the assembly accuracy of the light-touch key unit 100 in the key groove 212.

In this embodiment, the two positioning portions 2123 are disposed on the groove surface of the key groove 212, so that the assembly accuracy of the tactile key unit 100 in the key groove 212 is ensured, and the structures of the housing 210 and the tactile key unit 100 in the key groove 212 can be simplified, which is helpful for further reducing the manufacturing cost of the electronic device 200.

FIG. 10 illustrates an exploded view of an assembly of a touch key unit from a second viewing angle.

Referring to fig. 9 and 10, the key assembly 10 may include a flexible pressing member 11, a second waterproof adhesive member 12, and a circuit board 13, and the flexible pressing member 11, the second waterproof adhesive member 12, and the circuit board 13 may constitute a touch key assembly. Circuit board 13 is located in key slot 212, interface member 132 is located on the side of circuit board 13 facing key slot 212 (i.e., the back side of circuit board 13), the side of circuit board 13 facing key slot 212 forms bonding surface 131 of key assembly 10, and first waterproof bonding member 20 is bonded to the side of circuit board 13 facing key slot 212. The side of the circuit board 13 opposite to the interface member 132 (i.e., the front side of the circuit board 13) has at least one tact-type key switch 133. That is, the side of the circuit board 13 opposite to the interface member 132 has one or a tact-type key switch 133. In this embodiment, the number of the key switches 133 on the circuit board 13 is not further limited.

Illustratively, the second waterproof adhesive 12 may include, but is not limited to, a 3M double-sided tape or a double-sided tape having waterproof property.

The flexible pressing member 11 is located on a surface of the circuit board 13 where the key switch 133 is located, and is bonded to the circuit board 13 by the second waterproof adhesive member 12, and the flexible pressing member 11 is configured to turn on the key switch 133 when pressed by an external force. Thus, while ensuring the key function of the key assembly 10, the flexible pressing member 11 can be bonded to the front surface of the circuit board 13 through the second waterproof bonding member 12, and the liquid entering the key groove 212 can be blocked from entering the front surface of the circuit board 13 to some extent, which helps to block the liquid in the key groove 212 at the side of the circuit board 13, thereby achieving the function of blocking water on the front surface of the circuit board 13 by the touch key unit 100, and effectively avoiding the liquid from damaging the key switch 133, the interface member 132 and other functional modules on the circuit board 13, so that the touch key unit 100 and the electronic device 200 have better waterproof performance.

By way of example, the flexible pressing member 11 may include, but is not limited to, a flexible material made of Polycarbonate (PC), Polyvinyl chloride (PVC), or other deformable materials. In the present embodiment, the material used for the flexible pressing member 11 is not further limited.

The circuit board 13 may be provided with a first positioning hole 134 at a position opposite to the positioning portion 2123, the first waterproof adhesive member 20 may be provided with a second positioning hole 22 at a position opposite to the positioning portion 2123, and the second positioning holes 22 are equal in number and correspond to the first positioning holes 134 one to one. The first positioning hole 134 and the second positioning hole 22 may constitute positioning holes on the touch key unit 100.

When the housing 210 is a metal frame, such as an aluminum frame, in order to avoid the contact between the interface 132 and the solder joint on the back of the circuit board 13 and the metal housing 210, as shown in fig. 7 to 10, the first waterproof adhesive member 20 further has a spacer portion 23, the spacer portion 23 is a bending structure that bends the edge of the avoiding hole 21 toward one side of the key slot 212, and the spacer portion 23 is located on the side where the solder joint is located and is opposite to the interface 132. When the key assembly 10 is fixed in the key slot 212 through the first waterproof adhesive member 20, the spacer 23 can shield the solder joint, so that the solder joint is isolated from the metal shell 210, thereby avoiding the metal isolation from contacting the solder joint and ensuring the safety performance of the electronic device.

As shown in fig. 6, the outer edge of the second waterproof adhesive 12 may extend toward the outside of the circuit board 13. Wherein the outer edge of the second waterproof adhesive 12 may have a distance from the outermost edge of the circuit board 13. Alternatively, the outer edge of the second waterproof adhesive 12 may be flush with the outermost edge of the circuit board 13. Alternatively, the outer edge of the second waterproof adhesive member 12 may extend out and be exposed to the outside of the circuit board 13, and be adhered to the groove surface of the key groove 212. Therefore, the area of the second waterproof bonding piece 12 can be increased to improve the bonding effect of the flexible pressing piece 11 and the front surface of the circuit board 13, and liquid entering the front surface of the circuit board 13 can be effectively blocked, so that the function of blocking water on the front surface of the circuit board 13 by the touch key unit 100 is realized.

As shown in fig. 9 and 10, the second waterproof adhesive member 12 has a through hole 121 through which the key switch 133 passes, and the through hole 121 is disposed opposite to the key switch 133. So that the key switch 133 can pass through the through hole 121 and be positioned under the flexible pressing member 11, the key switch 133 can be turned on by the flexible pressing member 11 when an external force acts on the flexible pressing member 11.

In order to facilitate the user to recognize the position of the key switch 133, the flexible pressing member 11 shown in fig. 9 and 10 has the flexible key 112 disposed opposite to the key switch 133 with a space between the flexible key 112 and the key switch 133 so as to generate a certain amount of deformation with respect to the key switch 133 by the flexible key 112. The flexible key 112 is configured to turn on the key switch 133 upon external force pressing. Specifically, when an external force acts on the flexible key 112 to force the flexible key 112 to deform toward one side of the key switch 133, the flexible key 112 will contact with the key portion of the key switch 133, and the key portion can move relative to the key switch 133 under the action of the flexible key 112, so that the key switch 133 is in an on state, and the key switch 133 is turned on. Accordingly, when the external force disappears, the flexible key 112 is deformed again, the key portion is automatically reset, and the inside of the key switch 133 is turned off, thereby turning off the key switch 133.

It should be noted that the structure, on and off principle of the key switch 133 can be referred to the related description of the light touch type key switch in the related art, and in this embodiment, it is not further explained.

The flexible press 11 may include a press body 111 and a flexible key 112, the flexible key 112 being integrally connected with the press body 111. The flexible key 112 may be a recessed portion recessed toward a side of the pressing body 111 away from the circuit board 13. When the flexible press piece 11 is adhered to the circuit board 13 by the second waterproof adhesive piece 12, the concave portion may be understood as a bulge structure on the press piece body 111. Thus, while the flexible key 112 and the key switch 133 are spaced, the thickness of the area of the touch key unit 100 except for the flexible key 112 can be reduced, which is helpful for making the touch key unit 100 thinner.

Alternatively, in some embodiments, flexible key 112 may also be a planar structure on pusher body 111. In the present embodiment, the structure of the flexible pressing member 11 is not further limited.

Referring to fig. 9 and 10, the circuit board 13 has a plurality of (e.g., three) key switches 133, and the second waterproof adhesive member 12 has a plurality of through holes 121, where the through holes 121 correspond to the key switches 133 one to one. The key switches 133 are respectively inserted into the corresponding through holes 121. When an external force acts on the flexible key 112 to force the flexible key 112 to deform toward one side of the key switch 133, air at a position corresponding to the flexible key 112 is gathered in the through hole 121 and cannot be discharged, thereby affecting the pressing hand feeling of the user on the touch key unit 100.

For this, referring to fig. 9 and 10, the second waterproof adhesive member 12 has at least one communication hole 121, and the communication hole 121 is located between adjacent two of the through holes 121. By the arrangement of the communication holes 121, when one of the flexible keys 112 deforms toward one side of the key switch 133 under the action of external force, air at the corresponding position of the flexible key 112 moves into the through hole 121 corresponding to the adjacent flexible key 112 along the communication hole 121, so that the pressing hand feeling of the user on the touch key unit 100 is enhanced.

It should be noted that, in the present embodiment, the waterproof level of the electronic device 200 at the key slot 212 may reach five levels or more, which can meet the daily use requirement of the electronic device 200.
