Description

Shell for protecting battery and electronic device

[ technical field ] A method for producing a semiconductor device

The present invention relates to a housing, and more particularly, to a housing for protecting a battery and an electronic device.

[ background of the invention ]

Users often carry portable electronic devices (e.g., tablet computers or smart phones) with them and use them in a variety of environments, and thus, compared to stationary or household electronic devices (e.g., desktop computers), the portable electronic devices have a higher possibility of liquid infiltration into them to cause malfunction (e.g., outdoor use in rainy days or use in water play). To avoid such a situation, more and more portable electronic devices have waterproof function.

The portable electronic device is provided with a battery, and generally, the battery of the portable electronic device can be built-in or separated. The built-in battery is integrated in the portable electronic device, so that the electric connection structure which is easy to allow liquid to permeate can be reduced, and the waterproof design is simpler. However, the built-in battery cannot be replaced, which causes inconvenience in use. The detachable battery is exposed to the exterior of the portable electronic device, and generally, a battery receiving groove is formed in the back of the portable electronic device, a socket is formed in the battery receiving groove, the detachable battery is installed in the battery receiving groove, and a plug of the detachable battery is inserted into the socket. Therefore, the separated battery can be electrically connected with the electronic component in the portable electronic device. The separate battery is generally replaceable, and thus more convenient in use. However, in the portable electronic device using the separated battery, the plug of the battery and the socket of the battery accommodating groove are electrically connected to allow liquid to permeate. Therefore, if the portable electronic device needs to have a higher waterproof function, an additional waterproof structure needs to be designed for the plug and the jack.

[ summary of the invention ]

The portable electronic device which adopts the separated battery design and has a higher-level waterproof function needs to design an additional waterproof structure aiming at the plug and the socket, so that the manufacturing procedure is complicated, and the cost of manpower or materials is higher. In view of the above, the present invention provides a casing and an electronic device for protecting a battery, so as to solve the problem of complicated manufacturing process and reduce the production cost.

In one embodiment of the present invention, a housing for protecting a battery includes a main body, an annular wall, and a waterproof member. The main body comprises a first side face, and the annular wall is connected with the first side face and extends towards a first direction far away from the first side face. The annular wall includes an annular groove that surrounds the annular wall and is recessed in the outer wall surface of the annular wall. The waterproof piece comprises an annular base part and an annular convex part, wherein the annular base part is arranged in the annular groove, and the annular convex part is positioned on the outer surface of the annular base part relative to the annular groove.

In an embodiment of the invention, the annular convex part further includes two opposite third sections, and one end of each third section is connected with the first section and extends along the second direction, so that the other end is connected with the second section. The first direction and the second direction form an angle, and the angle is greater than 0 degree and less than 90 degrees.

The first section and the second section are substantially parallel to each other, and the third section is arc-shaped. Further, the path length of the first section is equal to the path length of the second section, and the path length of the first section is greater than the path length of the third section.

In an embodiment of the invention, the first section comprises a first steep slope side and a first gentle slope side opposite to each other, the first steep slope side being close to the first side face with respect to the first gentle slope side. The second section comprises a second steep slope side and a second gentle slope side which are opposite, and the second gentle slope side is close to the first side face relative to the second steep slope side.

In an embodiment of the invention, the annular base comprises opposing first and second sections. The first section of the annular base is adjacent the first side relative to the second section of the annular base, the first section of the annular protrusion is disposed on the first section of the annular base, and the second section of the annular protrusion is disposed on the second section of the annular base.

In an embodiment of the present invention, the first section of the annular base portion has a first width along the first direction, the second section of the annular base portion has a second width along the first direction, and the first width is greater than the second width.

In an embodiment of the present invention, the elasticity of the waterproof member is greater than the elasticity of the annular wall.

In an embodiment of the invention, the annular wall and the waterproof member are two-material injection members, and the waterproof member is formed on the annular wall by a two-material injection molding process.

The battery module is detachably arranged in the battery accommodating groove and comprises the shell and a battery, and the battery is positioned in the shell. The battery includes a connection unit, and an annular wall surrounds the connection unit. The annular wall penetrates through the connecting port, so that the connecting unit can be electrically connected with the electronic component. Wherein the waterproof member is positioned between the connection port and the annular wall, the first section of the annular convex part is abutted against the first edge of the connection port, and the second section of the annular convex part is abutted against the second edge of the connection port.

[ detailed description ] embodiments

Referring to fig. 1, fig. 1 is a schematic view of a case 100 for protecting a battery according to an embodiment of the invention. In this embodiment, a battery (not shown) may be disposed inside the housing 100. The housing 100 includes a body 110, an annular wall 120, and a waterproof member 130. In the present embodiment, the body 110 is a hexahedron, but is not limited thereto. The main body 110 includes a first side surface 111 and a second side surface 112, and the first side surface 111 and the second side surface 112 are two surfaces adjacent to and perpendicular to each other on the main body 110. The annular wall 120 connects the first side 111 and extends in a first direction O1 away from the first side 111. The battery can be disposed inside the main body 110, and an electrical connection terminal (not shown) of the battery can pass through the first side 111 of the main body 110 and be positioned in the annular wall 120 (i.e., the annular wall 120 surrounds the electrical connection terminal).

Referring to fig. 2 and 3 again, fig. 2 is an enlarged schematic view of the annular wall 120 and the waterproof member 130 of fig. 1, and fig. 3 is a schematic view of the waterproof member 130 separated from the annular wall 120. The annular wall 120 defines an outer wall surface 122, and the annular wall 120 includes an annular groove 121, the annular groove 121 being recessed in the outer wall surface 122 and surrounding the annular wall 120. The waterproof member 130 includes an annular base portion 131 and an annular protrusion 132, the annular base portion 131 is disposed in the annular groove 121, and the annular protrusion 132 is located on an outer surface 1314 of the annular base portion 131 relative to the annular groove 121. In the present embodiment, the annular wall 120 and the waterproof member 130 are two-material injection (DoubleInjection) members. In other words, the waterproof member 130 is formed on the annular wall 120 by a two-shot molding process. For example, in the injection molding process, the raw materials of the body 110 and the annular wall 120 can be injected into the mold in the first stage, and the body 110, the annular wall 120 and the annular groove 121 are molded in the first stage. Then, without demolding the body 110 and the annular wall 120, the raw material of the waterproof member 130 is injected into the mold at the second stage, and the annular base 131 is directly formed in the annular groove 121. After demolding, the body 110, the annular wall 120 and the waterproof member 130 can be molded. Thus, the production process can be simplified, and the connection strength between the waterproof member 130 and the annular wall 120 can be improved. The elasticity of the waterproof member 130 is greater than that of the annular wall 120; alternatively, the Young's Modulus of the material of the waterproof member 130 is smaller than that of the material of the annular wall 120. For example, but not limited to, the waterproof member 130 is made of rubber, and the annular wall 120 is made of polystyrene.

Referring to fig. 2 to 4, fig. 4 is a schematic view of the waterproof member 130 and the annular wall 120 of fig. 2 from another view angle. The annular base 131 includes a first section 1311, a second section 1312, and two third sections 1313, the first section 1311 and the second section 1312 of the annular base 131 being opposite to each other, the two third sections 1313 of the annular base 131 being opposite to each other, and the third section 1313 being located between the first section 1311 and the second section 1312. The first section 1311, the second section 1312 and the two third sections 1313 of the ring-shaped base 131 together form a complete ring-shaped structure. Annular projection 132 includes a first segment 1321, a second segment 1322, and two third segments 1323, wherein first segment 1321 and second segment 1322 are opposite to each other, two third segments 1323 of annular projection 132 are opposite to each other, and third segment 1323 is located between first segment 1321 and second segment 1322. The first segment 1321, the second segment 1322 and the two third segments 1323 of the annular protrusion 132 together form a complete annular structure. The first section 1321 of the annular projection 132 is arranged on the first section 1311 of the annular base 131, the second section 1322 of the annular projection 132 is arranged on the second section 1312 of the annular base 131, and the two third sections 1323 of the annular projection 132 are arranged on the two third sections 1313 of the annular base 131, respectively.

Referring to fig. 5 to 7, fig. 5 is a front view of the waterproof member 130 and the annular wall 120, fig. 6 is a side view of the waterproof member 130 and the annular wall 120, and fig. 7 is a cross-sectional view taken along line 7-7 of fig. 5. In the present embodiment, as shown in fig. 5, the first segment 1321 and the second segment 1322 of the annular protrusion 132 are substantially parallel to each other, and the third segment 1323 of the annular protrusion 132 is arc-shaped. That is, the annular protrusion 132 is generally oblong in a front view of the annular wall 120 (see fig. 5), but is not limited thereto. As shown in fig. 6 and 7, the first segment 1321 of the annular projection 132 is close to the first side surface 111 relative to the second segment 1322, and one end of each third segment 1323 of the annular projection 132 is connected to the first segment 1321 and extends in the second direction O2 (refer to fig. 6), so that the other end is connected to the second segment 1323. The first direction O1 and the second direction O2 form an angle θ, and the angle θ is greater than 0 degree and less than 90 degrees. That is, the annular protrusion 132 is inclined with respect to the annular wall 120 in a side view of the annular wall 120 (see fig. 6).

As shown in fig. 2 to 5, the path length of the first segment 1321 and the second segment 1322 of the annular convex portion 132 is defined as the straight line length between the two third segments 1323, and the path length of the third segment 1323 of the annular convex portion 132 is defined as the arc length between the first segment 1321 and the second segment 1322, in this embodiment, the path length of the first segment 1321 of the annular convex portion 132 is equal to the path length of the second segment 1322, and the path length of the first segment 1321 of the annular convex portion 132 is greater than the path length of the third segment 1323. Further, as shown in FIG. 6, the outer surface 1314 of the annular base 131 is cut flush with the outer wall surface 122 of the annular wall 120.

As shown in fig. 6 and 7, the first section 1321 of the annular projection 132 includes a first steep slope side 1324 and a first gentle slope side 1325 that are opposed, wherein the first steep slope side 1324 is adjacent to the first side surface 111 relative to the first gentle slope side 1325. The second segment 1322 of the annular projection 132 includes a second steep slope side 1326 and a second gentle slope side 1327 that are opposite, and the second gentle slope side 1327 is adjacent to the first side surface 111 relative to the second steep slope side 1326. The first steep slope side 1324 and the second steep slope side 1326 represent surfaces forming a steeper (or more varying slope) slope, and the first gentle slope side 1325 and the second gentle slope side 1327 represent surfaces having a steeper (or less varying slope) slope.

Specifically, the first section 1311 of the annular base 131 has a first width W1 in the first direction O1, the second section 1312 of the annular base 131 has a second width W2 in the first direction O1, and the first width W1 is greater than the second width W2. The first section 1321 of the annular projection 132 is located on a side of the first section 1311 of the annular base portion 131 close to the first side surface 111, and the second section 1322 of the annular projection 132 is located on a side of the second section 1312 of the annular base portion 131 remote from the first side surface 111.

Referring to fig. 8 and 9, fig. 8 is a schematic view of an electronic device 10 according to an embodiment of the invention, and fig. 9 is a schematic view of a battery module 300 and a device body 200 in a separated state. In the present embodiment, the electronic device 10 is a tablet computer, but is not limited thereto. The electronic device 10 includes a device body 200 and a battery module 300, wherein the device body 200 includes an electronic component (not shown) and a housing 210, and the electronic component is disposed in an inner space of the housing 210. The electronic components are, for example, a motherboard, a chip and a memory disposed on the motherboard, and a display module and a hard disk electrically connected to the motherboard. The battery module 300 is a separate type that can be mounted to the pack body 200 and forms an integral external appearance with the pack body 200. When the battery module 300 is properly mounted to the device body 200, the battery module 300 is electrically connected to and can supply power to the electronic components.

As shown in fig. 9, the housing 210 defines a battery receiving groove 211, and the battery receiving groove 211 includes a groove wall 2111 and a groove bottom 2112 which are annularly closed. A portion of the groove wall 2111 defines a connection port 212, and the connection port 212 communicates the battery receiving groove 211 with the inner space of the housing 210. The connection port 212 includes a first side 2121 and a second side 2122 opposite to each other, and the first side 2121 is close to the groove bottom 2112 of the battery accommodation groove 211 relative to the second side 2122. The battery module 300 is detachably disposed in the battery receiving groove 211, and the battery module 300 includes the housing 100 shown in fig. 1 to 7 and a battery (not shown), and the battery is located in the housing 100. As shown in fig. 9, the housing 100 of the battery module 300 is inclined with respect to the battery receiving groove 211, so that the battery module 300 can be easily mounted on the device body 200 or dismounted from the device body 200, as described in detail later.

Referring to fig. 10 and 11 again, fig. 10 is a sectional view illustrating a process in which the battery module 300 is mounted to the pack body 200, wherein the annular wall 120 is inclined into the connection port 212, and fig. 11 is a sectional view illustrating the battery module 300 of fig. 10 mounted to the pack body 200. It should be noted that the housing 100 of the battery module 300 shown in fig. 8-11 is upside down relative to the housing 100 shown in fig. 1-7, i.e., the second side 112 of the housing 100 and the first segment 1321 of the annular protrusion 132 shown in fig. 8-11 are located below the drawing. The battery includes a connection unit 310, and the connection unit 310 protrudes from the first side 111 and is located in the annular wall 120, i.e. the annular wall 120 surrounds the connection unit 310. The connection unit 310 is, for example, a plurality of metal pins spaced from each other or a plurality of metal sheets spaced on the tongue plate.

When the user wants to mount the battery module 300 to the device body 200, as shown in fig. 10, the battery module 300 is first tilted with respect to the battery receiving groove 211 such that the annular wall 120 is aligned with the connection port 212 and slightly enters the connection port 212. At this time, the second side 112 of the battery module 300 and the groove bottom 2112 form an acute angle, and the first segment 1321 of the annular protrusion 132 is adjacent to the first edge 2121 of the connection port 212, and the second segment 1322 of the annular protrusion 132 is adjacent to the second edge 2122 of the connection port 212. In this case, since the second segment 1322 is farther from the first side 111 than the first segment 1321, the second segment 1322 extends further into the connection port 212 than the first segment 1321. Then, the battery module 300 is rotated (counterclockwise in fig. 10) while the annular wall 120 continues to enter the connection port 212, and during the process that the annular wall 120 enters the connection port 212, an included angle between the second side surface 112 of the battery module 300 and the groove bottom 2112 is gradually reduced, that is, an inclination degree of the battery module 300 relative to the battery accommodation groove 211 is gradually reduced. As the annular wall 120 gradually enters the connection port 212 and the inclination degree of the battery module 300 with respect to the battery accommodation groove 211 gradually decreases, the second section 1322 of the annular protrusion 132 first contacts the second edge 2122 of the connection port 212, and the first section 1321 of the annular protrusion 132 does not contact the first edge 2121 of the connection port 212 until the included angle between the second side surface 112 and the groove bottom 2112 decreases to a certain extent (e.g., less than 30 degrees), at which time, the first section 1321 of the annular protrusion 132 and the first edge 2121 contact each other, and a friction force is generated due to the relative movement therebetween. When the first section 1321 hits the first edge 2121, the annular wall 120 enters the connection opening 212 slightly and the battery module 300 rotates slightly, i.e., as shown in fig. 11, the second side surface 112 is aligned with the groove bottom 2112 and the first side surface 111 is aligned with the groove wall 2111. At this time, the battery module 300 is properly mounted on the device body 200, the annular wall 120 is properly inserted into the connection port 212, and the connection unit 310 is electrically connected to the electronic components.

In a state where the battery module 300 is properly mounted to the pack body 200, the annular protrusion 132 is interposed between the annular wall 120 and the inner wall surface of the connection port 212 to achieve a waterproof effect. Specifically, the first segment 1321 of the annular protrusion 132 abuts against the first edge 2121 of the connection port 212, the second segment 1322 abuts against the second edge 2122, and the third segment 1323 abuts against the remaining portion of the connection port 212, thereby forming a waterproof structure. Moreover, because the waterproof member 130 is made of a material with high elasticity (compared with the materials of the annular wall 120 and the connecting port 212), the annular protrusion 132 is slightly deformed due to the compression, so as to more closely adhere to the inner wall surface of the connecting port 212 to fill the gap between the connecting port 212 and the annular wall 120, thereby achieving a better waterproof effect.

As described above, in the process of mounting the battery module 300 to the device body 200, the second segment 1322 of the annular protrusion 132 and the second edge 2122 of the connection port 212 contact each other with less stroke of relative movement (because the second segment 1322 has penetrated into the connection port 212 when the second segment 1322 hits the second edge 2122); also, the first segment 1321 and the first edge 2121 contact each other and move relatively with less travel (because the first segment 1321 is closer to the first side 111, the first segment 1321 does not structurally extend into the connection port 212 as the second segment 1322 does). Overall, when the battery module 300 is mounted in the device body 200, the less friction is generated between the annular protrusion 132 and the connection port 212, which means less resistance to the user when mounting the battery module 300. As a result, the process of mounting the battery module 300 to the device body 200 by the user is smoother and more labor-saving.

In addition, as shown in fig. 10 and 11, when the first stage 1321 of the annular protrusion 132 and the first side 2121 of the connection port 212 contact each other and move relatively during the installation of the battery module 300 to the device body 200, the first gentle slope side 1325 first contacts the first side 2121 and moves relatively to the first side 2121, and the slope of the first gentle slope side 1325 is gentle, so that it is helpful to reduce the friction force when the first stage 1321 and the first side 2121 move relatively to increase the smoothness of the installation of the battery module 300.

When the user wants to detach the battery module 300 from the device body 200, the above-described process may be reversed. During the reverse operation, the second segment 1322 of the annular projection 132 and the second edge 2122 of the connection port 212 contact each other and move relatively with a small stroke, and the first segment 1321 and the first edge 2121 contact each other and move relatively with a small stroke. In general, when the battery module 300 is detached from the device body 200, the frictional force generated between the annular protrusion 132 and the connection port 212 is small, which means that the user has less resistance to detachment of the battery module 300. Thus, the process of detaching the battery module 300 from the device body 200 by the user is smoother and more labor-saving.

In addition, as shown in fig. 10 and 11, when the second side surface 112 of the battery module 300 is rotated clockwise (the rotation direction is shown in fig. 10 and 11) with respect to the groove bottom 2112 during the detachment of the battery module 300 from the device body 200, the second segment 1322 of the annular projection 132 is also rotated clockwise while contacting the second side 2122 of the connection port 212, and at this time, the slope of the second gentle slope side 1327 is gentle, so that the resistance to the clockwise rotation of the second segment 1322 is small, and the smoothness of the battery module 300 during the detachment is increased.

Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made without departing from the spirit and scope of the invention as defined by the appended claims.
