Description

Adhesive parts and electronic devices containing the same

The disclosure relates to a glued part, in particular to a glued part combining two casings and an electronic device including the glued part.

With the advancement of technology, most electronic products are becoming thinner and more beautiful. Therefore, many original designs have to be improved in response to the limited space. For example, the casing of an electronic device can no longer be locked with screws or hooks, but instead of the traditional locking method and reinforcement structure, glue is used.

However, due to the inconsistent environmental factors such as temperature and humidity during the transportation of electronic devices, it is easy to cause the problem of glue peeling (ie, glue peeling due to incomplete adhesion) in mass-produced models.

In addition, if the electronic device has a display screen, the problem of water vapor infiltrating into the screen is more likely to occur. Although designers of electronic devices try to increase the sticking area or amount of glue by over design, they can only achieve the anti-splashing effect, but cannot discharge the internal water vapor out of the shell of the electronic device. , and then damage the electronic components inside the electronic device, or cause water marks on the display screen due to moisture entering between the display and the glass cover.

In view of the above problems, the main purpose of this disclosure is to provide a glued part and an electronic device including the glued part, through the guiding channel of the glued part, to solve the problem that the colloidal structure of the conventional electronic device cannot discharge the internal moisture The problem.

To achieve the above purpose, the present disclosure provides a glued part. The glued part includes a body and a guide channel, and the guide channel is arranged on the body. The guiding channel includes a first channel and a second channel. There is a first angle between the first channel and the second channel.

To achieve the above purpose, the present disclosure further provides an electronic device, which includes a first casing, a second casing, and an adhesive member. The first casing includes a mounting portion. The glued part is arranged on the installation part and connects the first casing and the second casing. The glued part includes a body and a guide channel, and the guide channel is arranged on the body. The guiding channel includes a first channel and a second channel. There is a first angle between the first channel and the second channel.

Based on the above, according to the glued piece and the electronic device including the glued piece of the present disclosure, the glued piece includes a body and a guiding channel. The guide channel can remove the moisture accumulated inside the electronic device, so as to avoid damage to the electronic components inside the electronic device and avoid water marks. Moreover, the guiding channel includes a first channel and a second channel, and there is an angle between the first channel and the second channel, so that the external water vapor can be further prevented from entering the electronic device directly.

FIG. 1 is an exploded view of an electronic device according to an embodiment of the present disclosure. FIG. 2 is a partial cross-sectional view of the assembled electronic device shown in FIG. 1 . FIG. 3 is a schematic view of the glued part shown in FIG. 1 . , Figure 2 and Figure 3. In this embodiment, the electronic device 1 includes a first casing 10 , a second casing 20 and a glued part 30 . The electronic device 1 can be an electronic device with a display screen, the first casing 10 can be a plastic casing, and the second casing 20 can be a glass panel of the display screen. In addition, the electronic device 1 further includes an electronic component 40 disposed in the first casing 10 .

The first casing 10 includes a mounting portion 11 located on the periphery of the first casing 10 for placing and assembling the second casing 20 . The second housing 20 is partially disposed on the installation portion 11 , that is, the peripheral edge of the second housing 20 is disposed on the installation portion 11 . In addition, the adhesive member 30 is also disposed on the installation portion 11 to connect the first housing 10 and the second housing 20 . Specifically, after forming the glued part 30 on the installation part 11 first, the second casing 20 is placed on the other side of the glued part 30 so that the glued part 30 can connect the first casing 10 and the second casing 20 .

As shown in FIG. 3 , the adhesive component 30 includes a body 31 and a guide channel 33 . In this embodiment, the first casing 10 and the second casing 20 are quadrangular, and correspondingly, the installation part 11 and the body 31 of the glued part 30 are also quadrangular. In this embodiment, the main body 31 is defined as an elongated portion 311 and a corner 312 according to the configuration of the main body 31 . In other words, the body 31 includes four elongated portions 311 and four corners 312 . The four elongated portions 311 are the four sides of the body 31 , and the four corners 312 are the four fan-shaped corners of the body 31 .

FIG. 4 is an enlarged schematic view of the elongated part of the body shown in FIG. 3 , and FIG. 5 is an enlarged schematic view of a corner of the body shown in FIG. 3 . Please refer to FIG. 2 , FIG. 3 , FIG. 4 , and FIG. 5 . In this embodiment, the corner 312 includes two sides 3121 and an arc 3122 . The two sides 3121 are connected, and the arc-shaped side 3122 is located between the two sides 3121 to form a fan-shaped structure, as shown in FIG. 5 . Moreover, the intersection point of the two sides 3121 is a center C of the corner 312 .

As shown in FIG. 4 , the guiding channel 33 of this embodiment is located at the elongated portion 311 of the main body 31 to remove moisture accumulated inside the electronic device 1 . It should be noted that, for simplicity of the drawing, the elongated portion 311 shown in FIG. 4 omits the dot pattern representing the material of the glued part 30 , and FIG. 4 only shows one side 3121 of the corner 312 . The guiding channel 33 includes a first channel 331 and a second channel 332 , the first channel 331 is close to the inside of the body 31 , and the second channel 332 is close to the outside of the body 31 . Wherein, the first channel 331 and the second channel 332 are linear channels, which may include straight channels or curved channels, which are not limited by the present invention.

Moreover, there is a first angle θ1 between the first channel 331 and the second channel 332 . Wherein, the first included angle θ1 is less than 90 degrees. Preferably, the first included angle θ1 is between 50 degrees and 80 degrees. The moisture inside the electronic device 1 can be discharged to the outside through the first channel 331 and the second channel 332 in sequence. Therefore, the design of the guide channel 33 can prevent moisture from accumulating inside the electronic device 1 , thus avoiding damage to the electronic components 40 inside the electronic device 1 and avoiding water marks.

Preferably, the guiding channel 33 is located close to the corner 312 , so each elongated portion 311 can be provided with two guiding channels 33 , as shown in FIG. 3 . In this embodiment, a shortest distance D1 between the corner 312 and the guiding channel 33 is between 10 mm and 20 mm. That is, the shortest distance D1 between one side 3121 of the corner 312 and the guiding channel 33 (for example, the second channel 332 is located at the opening of the outer side wall of the main body) is between 10 mm and 20 mm.

Preferably, the body 31 has an inner wall 313 , and the inner wall 313 is close to the first channel 331 , that is, close to the inner side of the body 31 , as shown in FIG. 3 . Moreover, the inner side wall 313 tapers from the corner 312 toward the guide channel 33 . Specifically, the width of the main body 31 is not uniform, and the portion close to the first channel 331 of the guiding channel 33 is relatively small. In this embodiment, there is a second included angle θ2 between the inner wall 313 and one side 3121 of the corner 312 . The second included angle θ2 is less than 90 degrees, so as to form a thinned structure on the inner side wall 313 of the body 31 , thereby guiding the water vapor to the first channel 331 . Preferably, the second included angle θ2 may be between 75 degrees and 87 degrees. Correspondingly, the thinned width T2 of the inner sidewall 313 of the main body 31 is between 0.25 mm and 1.0 mm. In addition, the inner diameter D2 of the opening of the first channel 331 may preferably be between 0.25 mm and 1.0 mm.

In addition, the first channel 331 and the second channel 332 are bent, that is, the first channel 331 and the second channel 332 have a first angle θ1, so that moisture outside the electronic device 1 can be prevented from entering the electronic device 1 at the same time. Preferably, the guiding channel 33 further includes a waterproof groove 333 disposed between the first channel 331 and the second channel 332 and located on a side opposite to the first included angle θ1. In other words, the waterproof groove 333 is located on the obtuse side of the guide channel 33 . Therefore, even if the moisture on the outside of the electronic device 1 enters the guide channel 33 through the second channel 332 , it can directly flow into the waterproof groove 333 to prevent the moisture from entering the electronic device 1 .

In this embodiment, a side of the waterproof groove 333 close to the inner wall 313 has a plane 3331 , and the opposite side can be an extension surface of the second channel 332 . Preferably, the width D3 of the plane 3331 may be between 0.5 mm and 2.0 mm. Preferably, there is a third included angle θ3 between the second channel 332 and the outer wall of the main body 31 , and the third included angle θ3 may range from 18 degrees to 33 degrees. In addition, the two sides of the plane 3331 can be arc surfaces, so that the entire guide channel 33 forms a similar inclined letter "R", so as to achieve better dual effects of eliminating internal moisture and preventing external moisture from entering. That is to say, if moisture enters the electronic device 1 through the second channel 332, the moisture can be accumulated in the waterproof groove 333 first, and the electronic device can release the moisture accumulated in the waterproof groove 333 while generating heat energy. It is evaporated and then discharged through the second channel 332 to further achieve the effect of buffering water vapor from entering the display area of the electronic device. In other embodiments, the waterproof groove 333 can also be a circular, oval, polygonal, or linear channel structure, which can also achieve the effect of preventing moisture from entering the interior of the electronic device 1 .

As shown in FIGS. 3 and 5 , the glued component 30 of this embodiment further includes at least one buffer groove 32 . The buffer slot 32 is disposed at the corner 312 , and the buffer slot 32 has a first side wall 321 . The first side wall 321 is close to the arc edge 3122 of the corner 312 , that is, the first side wall 321 is close to the outside. Moreover, there is a first distance S1 between the first side wall 321 and the arc-shaped side 3122 , and the first distance S1 is smaller than the maximum width T1 of the main body 31 . Wherein, the length of the side 3121 is the maximum width T1 of the main body 31 . In other words, the buffer groove 32 is disposed inside the corner 312 . Preferably, the ratio of the first distance S1 to the maximum width T1 may be between 0.3 and 0.6. In this embodiment, the maximum width T1 of the body 31 may be between 3 millimeters (mm) and 20 millimeters. Correspondingly, the first distance S1 between the first side wall 321 and the arc-shaped side 3122 may be between 0.9 millimeters and 12 millimeters.

Preferably, the first sidewall 321 may be arc-shaped and parallel to the arc-shaped side 3122 of the corner 312 . The buffer slot 32 has a second side wall 322 . The second side wall 322 is close to the center C of the corner 312 , and there is a second distance S2 between the second side wall 322 and the center C of the circle. Likewise, the second distance S2 is smaller than the maximum width T1 of the body 31 (ie the length of the side 3121 ). Preferably, the ratio of the second spacing S2 to the maximum width T1 is between 0.15 and 0.3. As mentioned above, the maximum width T1 of this embodiment is between 3 mm and 20 mm, and correspondingly, the second distance S2 between the second side wall 322 and the center C may be between 0.45 mm and 6 mm. Preferably, the second side wall 322 is also arc-shaped and parallel to the first side wall 321 and the arc-shaped side 3122 of the corner 312 .

The buffer groove 32 provided inside the corner 312 of the main body 31 can effectively reduce the peeling rate of the four corners of the electronic device 1 , which means that the impact energy of corner drop can be dissipated without replacing the high-viscosity glue. Specifically, a drop test will be performed after the electronic device 1 is assembled. When the four corners of the electronic device 1 are dropped, the buffer groove 32 can absorb the impact force, so as to reduce the probability of peeling off the adhesive part 30 from the second casing 20 (or the first casing 10 ). According to tests, the design of the buffer groove 32 can reduce the peeling rate of the four corners of the electronic device 1 by at least 3%. In this embodiment, both the first sidewall 321 and the second sidewall 322 are arc-shaped, which can reduce the peeling rate of the four corners of the electronic device 1 by about 29%. In other embodiments, the buffer groove 32 can also be a trapezoidal structure, that is, the first sidewall 321 and the second sidewall 322 are designed to be straight, which can reduce the peeling rate of the four corners of the electronic device 1 by about 10%. In other embodiments, the buffer groove 32 is rhomboid, triangular, or circular, and the peeling rate can be reduced by 6%, 5%, or 3%, respectively.

To sum up, according to the electronic device and its glued part of the present disclosure, the glued part includes a main body and a guiding channel. The guide channel can remove the moisture accumulated inside the electronic device, so as to avoid damage to the electronic components inside the electronic device and avoid water marks. In addition, the guiding channel includes a first channel and a second channel, which can further prevent external moisture from directly entering into the electronic device.
