The same or similar components have the same or similar reference numbers in all the drawing figures. The embodiments described below are merely examples for explaining the present application and should not be understood as limiting the present application.

[0023] Unless otherwise defined, technical terms or scientific terms used herein should be understood as having the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0024] In this document, the term "axis" refers to the axis or central axis x of the electronic device. The term "axial" or "axial direction" refers to the direction along the axis of the electronic device, the term "circumferential" refers to the direction around the axis x, the term "radial" or "radial direction" refers to the direction substantially perpendicular to the axis, pointing towards or away from the axis, the term "radially inner" or "radially in" refers to a component, part, position or direction relatively close to the axis, and the term "radially outer" or "radially out" refers to a component, part, position or direction relatively far from the axis.

[0025] The present application provides an electronic device comprising a first housing member, a second housing member and a circuit portion, wherein a peripheral wall of the first housing member is arranged parallel and adjacent to a peripheral wall of the second housing member, thereby forming a first gap therebetween, the first housing member further comprises a protrusion adjacent to the peripheral wall thereof, the protrusion being in contact with a base portion of the second housing member. In one or more embodiments, the protrusion has a tapered head in contact with the base portion of the second housing member. In another one or more embodiments, the protrusion is pressed against the base portion of the second housing member.

[0026] During use of the electronic device, the elongated dimensional gap between the first housing member perimeter wall and the second housing member perimeter wall effectively prevents moisture or humidity from entering the interior of the electronic device along the gap. In addition, the contact or pressure between the protrusion of the first housing member and the base of the second housing member effectively achieves a close fit between the first housing member and the second housing member radially inward of the first gap. This configuration effectively prevents water (that enters through the first gap) from entering the interior of the electronic device.

[0027] In one or more embodiments, the protrusion has a second gap with the first housing member perimeter wall, the second gap having a width that is greater than the first gap, e.g., 2 to 6 times the width of the first gap. In one or more embodiments, the second gap is axially aligned with the first gap.

[0028] Even if a small amount of water or humidity enters through the first gap between the first housing member perimeter wall and the second housing member perimeter wall during certain use conditions of the electronic device, the water or humidity will tend to accumulate in the second gap rather than continuing to enter the interior of the electronic device. Thus, the second gap effectively acts as a water reservoir to prevent water or humidity from entering the interior of the electronic device.

[0030] As shown, the electronic device 100 has an axis x and includes a first housing member or upper housing member 110 and a second housing member or lower housing member 140. The first housing member 110 and the second housing member 140 cooperate to define a containment space therebetween. The electronic device 100 also includes a circuit portion 160 disposed in the containment space defined by the first housing member 110 and the second housing member 140.

[0031] ​​The first housing member 110 includes a first housing member base 112 and a first housing member peripheral wall 130 that surrounds the first housing member base 112 and extends from the first housing member base 112 in a first axis direction or downward direction. The first housing member 110 also includes a heat dissipation fin 114 formed above the first housing member base for heat dissipation of the electronic device 100. In one or more embodiments, the heat dissipation fin 114 can be a separate component that is attached to the first housing member base 112. In one or more additional embodiments, the heat dissipation fin 114 can be integrally formed with the first housing member base 112. The electronic device 100 also includes a connection port 116 formed on the first housing member base 112 of the first housing member 100. The connection port 116 is adapted to be connected to an external power source or electrically signal connected to other electronic devices via an adapted connector.

[0032] In the embodiment as shown, the first housing member base 112 includes a base peripheral wall 122. The base peripheral wall 122 surrounds the rest of the first housing member base 112 and extends from it in the first axis direction or downward direction. The base peripheral wall 122 has a greater thickness compared to the first housing member peripheral wall 130. The base peripheral wall 122 and the first housing member peripheral wall 130 are flush on the outside, thereby providing a complete flat side appearance for the electronic device 100.

[0033] The second housing member 140 has a second housing member base 142 and a second housing member peripheral wall 150 that surrounds the second housing member base 142 and extends from the second housing member base 142 in the first axis direction or downward direction. The second housing member 140 can be connected to the first housing member 110 by any suitable means, such as mechanical connection means (not shown) such as screw connection or snap connection, etc.

[0034] In one or more embodiments according to the present application, the first housing member 110 is a one-piece cast metal member. In one or more embodiments according to the present application, the second housing member 140 is a one-piece stamped metal member or sheet metal member. In one or more additional embodiments according to the present application, the first and second housing members can be formed by any suitable forming method.

[0035] Figure 4 is Figure 3A magnified view of portion B in FIG. 1 A. As shown, the first housing piece perimeter wall 130 is parallel and adjacent to the second housing piece perimeter wall 150, forming a gap 132 therebetween. In the embodiment shown, the gap between the first housing piece perimeter wall 130 and the second housing piece perimeter wall 150 has a width wl of about 0.5 mm and a length L of about 5 mm or more. In one or more embodiments according to the present disclosure, the gap 132 between the first housing piece perimeter wall 130 and the second housing piece perimeter wall 150 can have a width wl in a range of 0.3 mm to 0.8 mm and a length L in a range of 3 mm to 10 mm. In one or more embodiments according to the present disclosure, the gap 132 between the first housing piece perimeter wall 130 and the second housing piece perimeter wall 150 can have a width wl in a range of 0.2 mm to 1.5 mm and a length L in a range of 4 mm to 15 mm. In one or more embodiments, the gap 132 between the first housing piece perimeter wall 130 and the second housing piece perimeter wall 150 can have a width wl in a range of 0.2 mm to 1.5 mm or in a range of 0.3 mm to 0.8 mm and a length L that is about 8, 10, 12, or more times the width wl. Such a long and narrow gap 132 between the first housing piece perimeter wall 130 and the second housing piece perimeter wall 150 can effectively prevent moisture or humidity from entering the interior of the electronic device 100 along the gap 132 during use of the electronic device 100.

[0036] The first housing piece 110 also includes a protrusion 124 formed on the base perimeter wall 122. The protrusion 124 extends from the base perimeter wall 122 in a first axis direction or downward direction, generally parallel to the first housing piece perimeter wall 130. In one or more embodiments according to the present disclosure, a gap 126 between the protrusion 124 and the first housing piece perimeter wall 130 has a width w2 that is greater than the width wl of the gap 132 between the first housing piece perimeter wall 130 and the second housing piece perimeter wall 150. In one or more embodiments according to the present disclosure, the width w2 of the gap 126 is 3-5 times the width wl of the gap 132. In one or more additional embodiments according to the present disclosure, the width w2 of the gap 126 is 2-6 times the width wl of the gap 132.

[0037] As shown, the gap 126 is axially aligned with and in communication with the gap 132, and the gap 126 has a greater width. Even if a small amount of water or moisture enters through the gap 132 between the first housing piece peripheral wall 130 and the second housing piece peripheral wall 150 in some use cases of the electronic device 100, the water or moisture will tend to accumulate in the gap 126 rather than continuing to enter the interior of the electronic device 100. Thus, the gap 126 can act as a water reservoir for the electronic device 100, temporarily storing a small amount of water or moisture that enters through the narrow gap 132 between the first housing piece peripheral wall 130 and the second housing piece peripheral wall 150, preventing it from further entering the interior of the electronic device 100.

[0038] As shown, the protrusion 124 has a tapered head 124a. In one or more embodiments, the tapered head 124a of the protrusion 124 contacts the second housing piece base of the second housing piece 140. In the embodiment as shown, the tapered head 124a of the protrusion 124 presses against the second housing piece base of the second housing piece 140. In the embodiment as shown, similar to the first housing piece peripheral wall 130, the protrusion 124 also extends around the entire perimeter of the first housing piece base 112. By pressing the tapered head 124a of the protrusion 124 against the second housing piece base of the second housing piece 140, a tight fit between the first housing piece 110 and the second housing piece 140 is achieved around the entire or substantially entire perimeter of the first housing piece base 112. In this configuration as shown, even if a small amount of water or moisture enters the gap 126 acting as a water reservoir through the gap 132, the tight fit between the first housing piece 110 and the second housing piece 140 achieved by the protrusion 124 effectively prevents the water from further entering the interior of the electronic device 100.

[0039] Thus, in the electronic device 100 of the present application, a sealing structure is achieved by the first housing piece peripheral wall 130, the second housing piece peripheral wall 150, and the protrusion 124, achieving the desired waterproof performance without the need to set up a special sealing material, such as sealing glue or sealing rubber. Compared with the sealing structure achieved by conventional sealing glue or sealing rubber, the sealing structure of the electronic device 100 of the present application is simple, low in cost, and simplifies the assembly process.
