[0001] This utility model relates to an electronic device, and more particularly to an electronic device with waterproof properties. Background Technology

[0002] Today, electronic devices and various types of displays are widely used in consumer electronics, automotive electronics, commercial and retail, gaming and entertainment, medical and healthcare, industrial and automation, and other fields. Taking a common electronic device as an example, the assembly tolerances must be considered when assembling the front and rear shells, so a certain gap must be reserved in the design.

[0003] However, the gap between the front and back covers of an electronic device may allow liquid to enter the device if cleaning fluid or other liquids are accidentally splashed onto the top or side of the device. This could cause short circuits in the internal electronic components, leading to malfunctions.

[0004] Therefore, how to propose an electronic device that can effectively solve the above problems is one of the issues that the industry is currently eager to invest research and development resources to address. Utility Model Content

[0005] In view of this, one object of this disclosure is to provide an electronic device that can solve the above-mentioned problems.

[0006] To achieve the above objectives, according to one embodiment of the present disclosure, an electronic device has opposing first and second sides, and opposing third and fourth sides. The electronic device includes a base, a rear shell, a front frame, and a plurality of waterproof foams. The rear shell is connected to the base adjacent to the second side. The front frame is detachably mounted to the rear shell. Waterproof foams are disposed between the rear shell and the front frame. The waterproof foams include a first waterproof foam, a second waterproof foam, a third waterproof foam, and a fourth waterproof foam. The first waterproof foam is disposed on the first side and partially extends to the third and fourth sides. The second waterproof foam is disposed on the second side. The third waterproof foam is disposed on the third side and partially extends to the second side. The fourth waterproof foam is disposed on the fourth side and partially extends to the second side.

[0009] In one or more embodiments disclosed herein, the two first interfaces and the two second interfaces are stepped.

[0010] In one or more embodiments disclosed herein, the third waterproof foam has two third joint surfaces respectively connecting the first waterproof foam and the second waterproof foam. The fourth waterproof foam has two fourth joint surfaces respectively connecting the first waterproof foam and the second waterproof foam.

[0011] In one or more embodiments disclosed herein, the two first contact surfaces are located on the third side and the fourth side, respectively. The two second contact surfaces are located together on the second side.

[0012] In one or more embodiments disclosed herein, the two first contact surfaces are respectively located at both ends adjacent to the first side. One of the two second contact surfaces is located at one end adjacent to the third side. The other of the two second contact surfaces is located at one end adjacent to the fourth side.

[0048] The following description, with reference to the accompanying drawings, illustrates several embodiments of this disclosure. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this disclosure. That is, in some embodiments of this disclosure, these practical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and elements will be shown in the drawings in a simplified schematic manner.

[0049] To help readers better understand the interrelationships and orientations of the various components, the accompanying diagram indicates the coordinate axes X as the first direction, Y as the second direction, and Z as the third direction. Furthermore, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0050] Please refer to Figure 1 and Figure 2 . Figure 1 A perspective rear view of an electronic device 10 according to one embodiment of the present disclosure is shown. Figure 2 For illustration Figure 1 An exploded view of electronic device 10. (See attached image.) Figure 1 and Figure 2 As shown, in this embodiment, the electronic device 10 includes a base 110, a rear shell 120, a front frame 130, and a display panel 140. The rear shell 120 and the display panel 140 are respectively disposed on opposite sides of the front frame 130, and the front frame 130 is detachably mounted on the rear shell 120. In this embodiment, the rear shell 120 is detachably connected to the base 110. Specifically, the base 110 can support the assembled rear shell 120, front frame 130, and display panel 140, so that the display panel 140 maintains a specific tilt angle (e.g., the angle facing the operator's viewing angle), thereby increasing the display effect of the electronic device 10.

[0051] like Figure 1 As shown, in this embodiment, the electronic device 10 includes, but is not limited to, wearable or portable display devices, consumer computer display devices, industrial computer display devices, point of sale (POS) display devices, kiosk self-service machines, or other embedded display devices.

[0052] like Figure 2 As shown, and in conjunction with reference Figure 1 In this embodiment, the electronic device 10 has opposing first sides 10a and second sides 10b, and opposing third sides 10c and fourth sides 10d. Specifically, the second side 10b is adjacent to the base 110; in other words, when the rear shell 120 is assembled on the base 110, the second side 10b is located at the lower edge of the electronic device 10. In this embodiment, due to the inertia of liquid flowing downwards, liquid or cleaning fluid splashed on the first side 10a, third side 10c, and fourth side 10d of the electronic device 10 will flow downwards and converge in the opposite direction of the second direction Y. To prevent liquid from entering the interior of the electronic device 10 from the first side 10a, third side 10c, and fourth side 10d during the downward flow, causing short circuits or corrosion of electronic components, a plurality of waterproof foams 150 are provided between the rear shell 120 and the front frame 130. The waterproof foams 150 can fill the gaps between the two caused by manufacturing tolerances. Waterproof foam 150 has a specific joint shape and connection method, which will be discussed in more detail below.

[0053] like Figure 2 As shown, in this embodiment, the waterproof foam 150 includes a first waterproof foam 150a, a second waterproof foam 150b, a third waterproof foam 150c, and a fourth waterproof foam 150d. The first waterproof foam 150a is disposed on the first side 10a and partially extends to the third side 10c and the fourth side 10d. In other words, the length of the first waterproof foam 150a is greater than the length of the first side 10a, and the two ends of the first waterproof foam 150a that extend beyond the length of the first side 10a are respectively bent downwards to the third side 10c and the fourth side 10d. In this embodiment, the second waterproof foam 150b is disposed on the second side 10b, and the length of the second waterproof foam 150b is less than that of the second side 10b, so that the second side 10b can reserve a portion of space for the third waterproof foam 150c and the fourth waterproof foam 150d to bend, allowing the third waterproof foam 150c disposed on the third side 10c and the fourth waterproof foam 150d disposed on the fourth side 10d to partially extend to the second side 10b. In this embodiment, the third waterproof foam 150c and the fourth waterproof foam 150d jointly connect the first waterproof foam 150a and the second waterproof foam 150b, and the length of the first waterproof foam 150a is greater than the length of the second waterproof foam 150b.

[0054] like Figure 2As shown, in this embodiment, by distributing the first waterproof foam 150a, the second waterproof foam 150b, the third waterproof foam 150c, and the fourth waterproof foam 150d on the four sides between the rear shell 120 and the front frame 130, rather than directly filling the waterproof foam 150 in a one-piece molding manner, the conformability of the waterproof foam 150 can be increased more effectively, allowing the waterproof foam 150 to fit more evenly on the four sides and avoiding poor sealing that may be caused by one-piece molding. In addition, the segmented design of the waterproof foam 150 can also alleviate the stress of thermal expansion and contraction, and avoid dimensional changes of the waterproof foam 150 under different temperature conditions (for example, the waterproof foam 150 may expand and deform due to the high temperature during use of the electronic device 10). Furthermore, the segmented design of the waterproof foam 150 can also improve the flexibility of the various components of the electronic device 10 during assembly, allowing the waterproof foam 150 on one side to be adjusted according to the tolerance dimensions between the rear shell 120 and the front frame 130 after assembly. Finally, the segmented design makes it easier to replace one side of the waterproof foam 150 individually when it ages or is damaged, reducing labor time and maintenance costs.

[0055] like Figure 2 As shown, and in conjunction with reference Figure 1 In this embodiment, the first waterproof foam 150a has two first contact surfaces 151a that respectively connect the third waterproof foam 150c and the fourth waterproof foam 150d, and the two first contact surfaces 151a are located on the third side 10c and the fourth side 10d, respectively. With this configuration, when the rear shell 120 is installed on the base 110, it can prevent liquid from directly entering the interior of the electronic device 10 from the most easily permeable contact surface due to the inertia of downward flow when liquid splashes or water vapor enters above the electronic device 10 (i.e., the first side 10a). In other words, when the rear shell 120 is installed on the base 110, the third side 10c and the fourth side 10d are substantially parallel to the direction of downward liquid flow (i.e., the opposite direction of the second direction Y), so liquid is less likely to remain on the third side 10c and the fourth side 10d compared to the first side 10a.

[0056] like Figure 2As shown, in this embodiment, in order to prevent liquid flowing downward through the third side 10c and the fourth side 10d from entering the electronic device 10, the joint surfaces of the third waterproof foam 150c and the fourth waterproof foam 150d, respectively connecting to the second waterproof foam 150b, are jointly disposed on the second side 10b to achieve a better waterproof effect. Specifically, the third waterproof foam 150c has two third joint surfaces 151c that connect to the first waterproof foam 150a and the second waterproof foam 150b, and the fourth waterproof foam 150d has two fourth joint surfaces 151d that connect to the first waterproof foam 150a and the second waterproof foam 150b, respectively. The third joint surfaces 151c and 151d are respectively matched with the first joint surfaces 151a and 151b connected to them. In other words, the contours of each joint surface of the waterproof foam 150 are substantially corresponding to each other. In this way, the waterproof foam 150 can be prevented from overlapping or having gaps due to mismatch between the joints, thus reducing the risk of liquid entering.

[0057] Please refer to Figure 3 It is a drawing Figure 2 A three-dimensional view of the waterproof foam 150 installed on the back cover 120. (See image below.) Figure 3 As shown, and in conjunction with reference Figure 2 In this embodiment, the waterproof foam 150 is disposed on the rear shell 120. Specifically, the electronic device 10 further includes a waterproof adhesive 160. During the assembly of the various components of the electronic device 10, the operator can first evenly apply the waterproof adhesive 160 to the rear shell 120, then adhere the waterproof foam 150 to the waterproof adhesive 160, and then assemble the front frame 130 and the display panel 140 in sequence, so that the waterproof foam 150 can seamlessly fill the gap between the rear shell 120 and the front frame 130. However, this disclosure is not limited to this. In some embodiments, the waterproof adhesive 160 can also be disposed on the front frame 130. The operator can first evenly apply the waterproof adhesive 160 to the front frame 130, and after the waterproof foam 150 adheres to the front frame 130, then assemble the rear shell 120 and the display panel 140 in sequence.

[0058] Please refer to Figure 4 It is a magnified drawing. Figure 3 A partial enlarged view of the electronic device 10 in the area marked by the dashed circle A. (See image below.) Figure 4 As shown, and in conjunction with reference Figure 2In this embodiment, the first joint surface 151a of the first waterproof foam 150a and the fourth joint surface 151d of the fourth waterproof foam 150d located on the fourth side 10d are non-flat surfaces. The non-flat surface design effectively improves the waterproof performance of the waterproof foam 150 because a non-flat joint surface is less likely to allow liquid to enter than a flush joint surface, thereby increasing the airtightness of the waterproof foam 150. Furthermore, the non-flat surface design can also increase the connection effect between the waterproof foams 150, preventing displacement or gaps caused by vibration or compression. In this embodiment, the first joint surface 151a and the fourth joint surface 151d are mutually matching stepped shapes, but this disclosure is not limited to this. In some embodiments, the first joint surface 151a and the fourth joint surface 151d can also be other mutually matching non-flat surfaces with specific shapes, such as serrated or other irregular shapes. It should be particularly noted that although... Figure 4 Only the joint surface of the waterproof foam 150 located on the fourth side 10d is shown, but in fact, the first waterproof foam 150a and the third waterproof foam 150c located on the third side 10c have the same non-flat surface design as described above, with their first joint surface 151a and third joint surface 151c connected.

[0059] Please refer to Figure 5 It is a magnified drawing. Figure 3 A partial enlarged view of the electronic device 10 in the area marked by the dashed circle B. (See image below.) Figure 5 As shown, and in conjunction with reference Figure 2 In this embodiment, the second joint surface 151b of the second waterproof foam 150b located on the second side 10b and the fourth joint surface 151d of the fourth waterproof foam 150d are non-flat surfaces. In this embodiment, the second joint surface 151b and the fourth joint surface 151d are also mutually matching stepped shapes. It should be noted that, although Figure 5 Only the joint surfaces of the second waterproof foam 150b and the fourth waterproof foam 150d located on the second side 10b are shown. However, in reality, the second joint surface 151b and the third joint surface 151c of the second waterproof foam 150b and the third waterproof foam 150c located on the second side 10b also have the above-mentioned non-flat surface design.

[0060] like Figure 4 and Figure 5 As shown, and in conjunction with reference Figure 2In this embodiment, the two first joint surfaces 151a of the first waterproof foam 150a are respectively located on the third side 10c and the fourth side 10d, adjacent to the two ends of the first side 10a. The two second joint surfaces 151b of the second waterproof foam 150b are respectively located on the second side 10b, adjacent to the two ends of the third side 10c and the fourth side 10d. In other words, each joint surface of the waterproof foam 150 is connected to each other near the four corners of the electronic device 10. In this embodiment, by setting each joint surface of the waterproof foam 150 near the side corners (rather than directly designing it in the corners or the middle section), it is possible to prevent the joint surfaces of the waterproof foam 150 from being located in stress concentration positions at the corners or easily deformable areas in the middle section after the rear shell 120 and the front frame 130 are combined, so that the joint surfaces of the waterproof foam 150 achieve a better sealing effect due to uniform stress distribution.

[0061] From the detailed description of the specific embodiments disclosed above, it is clear that in the electronic device disclosed herein, by providing waterproof foam between the rear shell and the front frame, the gap caused by manufacturing tolerances between the rear shell and the front frame can be filled. The segmented design of the waterproof foam increases the sealing effect on each side of the electronic device, alleviates the stress of thermal expansion and contraction, and increases the flexibility of replacing the waterproof foam on a single side. By placing the joint surfaces of the waterproof foam on the second, third, and fourth sides respectively, the flow of liquid can be oriented to prevent moisture intrusion on the most vulnerable side. The non-flat joint surface design of the waterproof foam increases its airtightness, achieving better sealing, dustproof, and waterproof effects.

[0062] Although the present disclosure has been described above with reference to embodiments, it is not intended to limit the present disclosure. Any person skilled in the art may make various modifications and refinements without departing from the spirit and scope of the present disclosure. Therefore, the scope of protection of the present disclosure shall be determined by the appended claims.
