Abstract
Description
Technical Field
[0001] This disclosure relates to a waterproof housing and an electronic device containing therein. Prior Technology
[0002] Currently, there are various waterproof electronic devices on the market, which usually require regular battery replacement or other maintenance. Therefore, the back cover design of the device must meet the following conflicting requirements at the same time: (1) airtightness / waterproofness: to ensure that the electronic components are not exposed to moisture or damage, the back cover must be tightly connected to the device body to prevent moisture from entering; (2) ease of disassembly: for easy battery replacement or maintenance, the back cover must be easily disassembled by the user; and (3) structural strength: the back cover must be strong enough to withstand the impact and pressure in daily use while maintaining airtightness.
[0003] However, existing technologies often encounter some challenges in meeting all of the above requirements: (1) Traditional embedded back cover design: After the back cover of this type of design is embedded in the device body, it forms a smooth surface with few gripping points, making it difficult to disassemble by hand. Furthermore, due to the tight airtightness between the back cover and the body, a vacuum suction force is generated during disassembly, further increasing the difficulty of disassembly; and (2) Existing unlocking structure: Although structures such as latches or buckles can be used to unlock the back cover, these structures can usually only unlock it and cannot provide enough force to push the back cover out.
[0004] Therefore, how to develop a waterproof casing that can solve the above problems is one of the issues that the industry is currently eager to address by investing research and development resources in. Summary of the Invention
[0005] In view of this, one of the purposes of this disclosure is to propose a waterproof casing that can solve the above-mentioned problems.
[0006] To achieve the above objectives, according to one embodiment of this disclosure, a waterproof housing includes a base, a cover, and a latching member. The base includes a latching portion and a first abutment. The cover is detachably connected to the base to form an internal space. The cover has a through hole. The latching member is disposed on the side of the cover facing the base and configured to move relative to the cover between a first position and a second position. The latching member includes a lever, a latching portion, and a second abutment. When the latching member is in the first position, the latching portion latches with the latching portion. During the movement of the latching member from the first position to the second position, the latching portion disengages from the latching portion, and the second abutment abuts against the first abutment, causing the cover to rise relative to the base.
[0007] In one or more embodiments disclosed herein, at least one of the first abutment and the second abutment is a ramp structure.
[0008] In one or more embodiments disclosed herein, the first abutment has a first ramp. The second abutment has a second ramp. During the movement of the latch from the first position to the second position, the second ramp slides relative to the first ramp after contacting it, causing the second abutment to rise relative to the first abutment.
[0009] In one or more embodiments disclosed herein, the waterproof housing further includes a waterproof ring. The waterproof ring is hermetically abutted between the inner edge of the base and the outer edge of the cover.
[0010] In one or more embodiments disclosed herein, the outer edge of the cover has an annular groove. A waterproof ring is hermetically disposed within the annular groove. When the cover is lifted relative to the base, the hermetically sealed contact between the waterproof ring and the base is at least partially released.
[0011] In one or more embodiments disclosed herein, the waterproof housing further includes at least one lifting mechanism. The lifting mechanism is disposed between the base and the cover and configured to push the cover away from the base.
[0012] In one or more embodiments disclosed herein, the lifting mechanism includes an elastic element and a lifting block. The elastic element is disposed on the base. The lifting block is connected to the elastic element and configured to lift the cover.
[0013] In one or more embodiments disclosed herein, the lifting mechanism includes two magnetic elements. The two magnetic elements are respectively disposed on the base and the cover, and are configured to generate magnetic repulsion between them.
[0014] In one or more embodiments disclosed herein, the waterproof housing further includes a reset member. The reset member is disposed between the cover and the latch member and configured to reset the latch member to a first position.
[0015] In one or more embodiments disclosed herein, the waterproof housing further includes an annular gasket. The annular gasket is disposed on the side of the cover facing the latch and surrounds the through-hole. The latch further includes an annular protrusion surrounding the lever. The annular protrusion abuts against the annular gasket in an airtight manner.
[0016] In one or more embodiments disclosed herein, the contact profile between the annular protrusion and the annular gasket is a closed ring.
[0017] In one or more embodiments disclosed herein, when the latch is in the first position, the contact profile between the annular protrusion and the annular washer is a closed annulus. When the latch is in the second position, the contact profile is a non-closed annulus.
[0018] In one or more embodiments disclosed herein, the annular gasket has a first cutout portion and a second cutout portion. The inner edge of the first cutout portion surrounds a through hole. The second cutout portion is connected to one side of the first cutout portion and extends away from the through hole.
[0019] To achieve the above objectives, according to one embodiment of this disclosure, an electronic device includes the aforementioned waterproof housing and a lens module. The lens module is disposed in the internal space and exposed from the side of the base away from the cover.
[0020] In summary, according to the waterproof housing disclosed herein, during the lateral movement of the latch relative to the cover by actuating the latching block, the second abutment of the latching member abuts against the first abutment of the base, causing the cover to rise relative to the base. This allows one side of the cover to tilt upwards, creating a gap with the base and releasing the airtightness between the base and the cover, facilitating further removal of the cover by the user. After one side of the cover rises relative to the base, a pushing mechanism located between the base and the cover assists in pushing the cover upwards, ensuring that the cover can smoothly spring up after the airtightness is released, reducing the need for manual operation by the user. During the lateral movement of the latching member relative to the cover, by switching the contact profile between the annular protrusion of the latching member and the annular gasket on the cover from a closed ring to a non-closed ring, the airtightness can be released in the initial stage of opening the cover, without waiting for the latching member to fully displace, thus helping to reduce the difficulty of opening the cover.
[0021] The above description is only used to illustrate the problem to be solved by this disclosure, the technical means to solve the problem, and the effects produced, etc. The specific details of this disclosure will be described in detail in the following implementation methods and related figures.

[0023] The following drawings disclose 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. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.
[0024] Please refer to Figure 1, which is a perspective view illustrating an electronic device 10 according to an embodiment of this disclosure. As shown in Figure 1, in this embodiment, the electronic device 10 includes a waterproof housing 100 and a lens module 200. The waterproof housing 100 includes a base 110 and a cover 120. The cover 120 is detachably connected to the base 110 to collectively form an internal space S of the electronic device 10 (see Figure 7A). The lens module 200 is disposed in the internal space S and is exposed from the side of the base 110 away from the cover 120. Thus, the electronic device 10 of this embodiment is a waterproof camera, but this disclosure is not limited thereto. In other embodiments, the electronic device 10 may further include other functional modules, such as a doorbell module, making the electronic device 10 a doorbell device with photographic functionality. In practical applications, the waterproof housing 100 disclosed herein can be used for any electronic product that requires waterproofing.
[0025] Please refer to Figures 2 and 3. Figure 2 is another perspective view illustrating the waterproof housing 100 in Figure 1. Figure 3 is an exploded view illustrating the waterproof housing 100 in Figure 2. As shown in Figures 2 and 3, in this embodiment, the base 110 includes a first housing portion 111, a second housing portion 112, and a third housing portion 113. The second housing portion 112 is disposed within the first housing portion 111 from one side of the first housing portion 111, and the cover 120 is detachably connected to the aforementioned side of the first housing portion 111 and covers the second housing portion 112. The third housing portion 113 is located outside the first housing portion 111 and is disposed on the other side of the first housing portion 111 away from the cover 120. Therefore, the first housing portion 111, the second housing portion 112, and the third housing portion 113 can respectively serve as an outer shell, an inner shell, and a decorative panel. The second housing portion 112 has a receiving groove 112a. For example, the receiving groove 112a is a battery slot. Therefore, maintaining the airtightness of the internal space S of the electronic device 10 can protect the normal operation of the electronic components installed in the internal space S.
[0026] In this embodiment, the first shell portion 111, the second shell portion 112, and the third shell portion 113 are each independent components, but this disclosure is not limited thereto. In other embodiments, at least one of the first shell portion 111, the second shell portion 112, and the third shell portion 113 may also be integrally formed to constitute a single-unit structure.
[0027] As shown in Figure 3, in this embodiment, the second shell portion 112 of the base 110 includes a latching portion 112b and a first abutment portion 112c. Please also refer to Figures 4, 5, and 6. Figure 4 is an exploded view showing some components of the waterproof housing 100 in Figure 3. Figures 5 and 6 are perspective views showing some components of the waterproof housing 100 in Figure 3. As shown in Figures 3 to 6, in this embodiment, the cover 120 has a through hole 121. The waterproof housing 100 further includes a latch 130 and a limiting plate 140. The limiting plate 140 is fixed to the side of the cover 120 facing the base 110. The latch 130 is disposed on the side of the cover 120 facing the base 110 and is positioned between the cover 120 and the limiting plate 140. The latch 130 is configured to move relative to the cover 120 along direction D (see Figure 4) between a first position (i.e., the position of the cover 120 in Figure 7A) and a second position (i.e., the position of the cover 120 in Figure 7B).
[0028] The following describes the technical means by which the seat 110 and the cover 120 achieve an airtight seal for the internal space S. As shown in Figures 3 and 4, the waterproof housing 100 further includes a waterproof ring 150. The waterproof ring 150 is airtightly abutted between the inner edge 111a of the first shell portion 111 of the seat 110 and the outer edge 120a of the cover 120. This prevents external moisture from entering the internal space S through the gap between the inner edge 111a of the first shell portion 111 and the outer edge 120a of the cover 120. Specifically, the outer edge 120a of the cover 120 has an annular groove 120a1. The waterproof ring 150 is airtightly disposed within the annular groove 120a1 to securely mount the waterproof ring 150 onto the cover 120. As shown in Figures 4 and 6, the waterproof housing 100 further includes an annular gasket 160. An annular gasket 160 is disposed on the side of the cover 120 facing the latch 130 and surrounds the through hole 121 of the cover 120. The latch 130 includes an annular protrusion 135. The annular protrusion 135 abuts against the annular gasket 160 in an airtight manner. The contact profile C between the annular protrusion 135 and the annular gasket 160 is a closed ring, as shown in Figure 6. This prevents external moisture from entering the internal space S through the through hole 121 of the cover 120. Thus, an airtight seal is formed between the seat 110 and the cover 120.
[0029] As shown in Figures 3 to 5, in this embodiment, the latch 130 further includes a body portion 131, a lever 132, a latch portion 133, and a second abutment 134. The body portion 131 is movably (in direction D) confined between the cover 120 and the limiting plate 140. The lever 132 is a protrusion connecting the body portion 131 and passing through the through hole 121 of the cover 120. The latch portion 133 connects to the body portion 131 and extends away from the cover 120. The second abutment 134 is connected to the side of the body portion 131 away from the cover 120. Specifically, the latch portion 133 is connected to the edge of the body portion 131 and extends away from the cover 120 through the edge of the limiting plate 140. The limiting plate 140 has a through groove 142, and the second abutment 134 passes through the through groove 142 of the limiting plate 140.
[0030] In this embodiment, the latch portion 133 is a hook-shaped structure, and the latch portion 112b is a slot structure. The inner surface of the latch portion 112b is configured for the latch portion 133 to latch. However, this disclosure is not limited to this.
[0031] Please refer to Figures 7A and 7B. Figure 7A is a partial cross-sectional view of the waterproof housing 100 in Figure 2 along line segment 7A-7A. Figure 7B is another partial cross-sectional view of the waterproof housing 100 in Figure 7A. In Figure 7A, the latch 130 is in a first position relative to the cover 120. In Figure 7B, the latch 130 is in a second position relative to the cover 120. When the latch 130 is in the first position relative to the cover 120, the latch portion 133 of the latch 130 latches with the latching portion 112b of the second housing portion 112 (refer to Figure 8A, where the latch portion 133 latches onto the inner surface of the latching portion 112b). During the movement of the latch 130 relative to the cover 120 from the first position to the second position, the latch portion 133 disengages from the latch portion 112b (see Figure 8B for reference), and the second abutment 134 of the latch 130 abuts against the first abutment 112c of the second shell portion 112. This causes the latch 130, positioned between the cover 120 and the limiting plate 140, to lift the cover 120 relative to the base 110. This allows one side of the cover 120 to tilt upwards, creating a gap with the base 110 and releasing the airtight seal between the base 110 and the cover 120, facilitating further removal of the cover 120 by the user. Specifically, when the cover 120 is lifted relative to the base 110, the tilted-up side of the cover 120 at least partially releases the airtight contact between the waterproof ring 150 and the base 110. The aforementioned airtight contact state being released may include a situation where at least a portion of the waterproof ring 150 is no longer in contact with the inner edge 111a of the first shell portion 111, and a situation where the waterproof ring 150 is in contact with the inner edge 111a of the first shell portion 111 but cannot prevent external moisture from passing between the two.
[0032] In practical applications, the waterproof ring 150 can also be fixed to the base 110. For example, the waterproof ring 150 can be set on the inner edge 111a of the first shell 111 by a two-material injection molding process so that the outer edge 120a of the cover 120 can make airtight contact.
[0033] As shown in Figures 3 and 5, in this embodiment, the first abutment 112c and the second abutment 134 are respectively located on one side (e.g., the left side) of the second shell 112 and the cover 120, so that the left side of the cover 120 rises relative to the base 110 when unlocked, but this disclosure is not limited thereto. In other embodiments, the combination of the first abutment 112c and the second abutment 134 can also be changed to be respectively provided on the other side (e.g., the right side) of the second shell 112 and the cover 120, so that the right side of the cover 120 rises relative to the base 110 when unlocked. In practical applications, the combination of the first abutment 112c and the second abutment 134 can also be provided on multiple sides of the waterproof shell 100.
[0034] As shown in Figures 3 to 5, in this embodiment, the number of combinations of the latch portion 133 of the latch member 130 and the latch portion 112b of the second housing portion 112 is six, but this disclosure is not limited to this and can be flexibly increased or decreased according to actual needs.
[0035] As shown in Figure 7A, in this embodiment, the first abutment 112c of the second shell portion 112 has a first inclined surface 112c1. The second abutment 134 of the cover 120 has a second inclined surface 134a. That is, both the first abutment 112c and the second abutment 134 are sloping structures. During the movement of the latch 130 from the first position to the second position, the second inclined surface 134a slides relative to the first inclined surface 112c1 after contacting it, causing the second abutment 134 to rise relative to the first abutment 112c.
[0036] As shown in Figure 7A, in this embodiment, both the first inclined surface 112c1 and the second inclined surface 134a are planar, but this disclosure is not limited thereto. In other embodiments, at least one of the first inclined surface 112c1 and the second inclined surface 134a may be a curved surface.
[0037] In practical applications, either the first abutment 112c or the second abutment 134 can be a ramp structure. For example, if one of the first abutment 112c and the second abutment 134 is a ramp structure and the other is a protrusion, the same purpose can be achieved by mutually abutting each other to lift the cover 120 relative to the seat 110.
[0038] As shown in Figures 4 and 7A, in this embodiment, the waterproof housing 100 further includes a reset member 170. The reset member 170 is disposed between the cover 120 and the latch member 130, and configured to reset the latch member 130 to a first position. Specifically, the reset member 170 is a spring. The body portion 131 of the latch member 130 includes a through groove 131a and a positioning post 131b extending within the through groove 131a. The limiting plate 140 includes a stop portion 141 passing through the through groove 131a of the body portion 131. The positioning post 131b of the body portion 131 extends toward the stop portion 141. The reset member 170 is sleeved on the positioning post 131b and abuts against the inner edge of the through groove 131a and the stop portion 141. Thus, the reset member 170 can continuously apply a force to the latch member 130 to reset it to the first position. The reset member 170 is housed in the through slot 131a of the body 131, which is a more compact mechanism design and helps to increase the space utilization of the internal space S of the waterproof housing 100.
[0039] In some other embodiments, the stop portion 141 may be disposed on the cover 120. In some other embodiments, the through groove 131a and the positioning post 131b may be disposed on the limiting plate 140, while the stop portion 141 may be disposed on the latch 130.
[0040] Please refer to Figures 8A and 8B. Figure 8A is a partial cross-sectional view of the waterproof housing 100 in Figure 2 along line segment 8A-8A. Figure 8B is another partial cross-sectional view of the waterproof housing 100 in Figure 8A. As shown in Figures 8A to 8C, in this embodiment, the waterproof housing 100 further includes a lifting mechanism 180. The lifting mechanism 180 is disposed between the base 110 and the cover 120 and is configured to push the cover 120 away from the base 110. The lifting mechanism 180 includes an elastic member 181 and a lifting block 182. The elastic member 181 is disposed on the base 110. The lifting block 182 is connected to the elastic member 181 and is configured to push the cover 120. Specifically, the second shell portion 112 of the base 110 further includes a limiting groove 112d and a positioning post 112e located within the limiting groove 112d. The elastic element 181 is housed within the limiting groove 112d. The elastic element 181, for example, is a spring or sheet spring, and is sleeved on the positioning post 112e. The push block 182 is housed within the limiting groove 112d and is configured to partially pass through the opening 112d1 of the limiting groove 112d to push against the limiting plate 140. The elastic element 181 is compressed between the positioning post 112e and the push block 182.
[0041] In Figure 8A, when the latch 130 is in the first position relative to the cover 120, the latch portion 133 of the latch 130 latches with the latching portion 112b of the second housing portion 112. At this time, the limiting plate 140 presses against the push block 182, causing the elastic member 181 to be compressed between the positioning post 112e and the push block 182. In Figure 8B, the latch 130 moves from the first position to the second position relative to the cover 120, and the latch portion 133 has disengaged from the latching portion 112b. Therefore, the cover 120 is lifted relative to the seat 110 and presents a state of tilting to one side. It should be noted that Figures 7B and 8B are different cross-sections of the same operating state of the waterproof housing 100. As shown in Figure 8C, after the latch 133 disengages from the latch 112b and the cover 120 is lifted relative to the base 110, the airtightness of the internal space S is released. Therefore, the elastic member 181 can release its elastic potential energy to partially push the push block 182 out of the slot 112d1, thereby further lifting the cover 120, which was already tilted relative to the base 110. In addition, the push block 182 has a hook 182a located in the limiting groove 112d and can hook onto the inner side of the slot 112d1 to prevent the push block 182 from completely disengaging from the limiting groove 112d. In this way, it can be ensured that the cover 120 can smoothly lift relative to the base 110 after the airtightness of the internal space S is released, reducing the need for manual operation by the user. In other words, after the airtightness of the internal space S is forcibly released by the combination of the first abutment 112c and the second abutment 134, the lifting mechanism 180 can assist the cover 120 in detaching from the base 110. In some other embodiments, the lifting mechanism 180 may also include two magnetic elements. The magnetic elements are, for example, magnets. The two magnetic elements may be respectively disposed on the base 110 and the limiting plate 140, and the ends of the two magnetic elements with the same polarity may be opposite each other to generate a magnetic repulsive force when the cover 120 is assembled to the base 110. This magnetic repulsive force can be used as the source of force for the cover 120 to spring up relative to the base 110.
[0042] As shown in Figure 3, in this embodiment, the number of lifting mechanisms 180 included in the waterproof housing 100 is four, but this disclosure is not limited to this and can be flexibly adjusted according to actual needs.
[0043] Please refer to Figure 9, which is a partial perspective view illustrating a cover 120 and an annular gasket 160A according to another embodiment of this disclosure. As shown in the embodiment of Figure 6, the inner edge of the annular gasket 160 is substantially square. As shown in the embodiment of Figure 9, the inner edge of the annular gasket 160A is not square. Specifically, the annular gasket 160A has a first cutout portion 161 and a second cutout portion 162. The inner edge of the first cutout portion 161 surrounds the through hole 121 of the cover 120. The second cutout portion 162 is connected to one side of the first cutout portion 161 and extends away from the through hole 121.
[0044] Please refer to Figures 10A, 10B, and 11. Figure 10A is a front view of the annular gasket 160A in Figure 9. Figure 10B is another front view of the annular gasket 160A in Figure 10A. Figure 11 is a partial cross-sectional view of a waterproof housing 100 according to another embodiment of this disclosure along line 7A-7A in Figure 2. In Figure 10A, the contact contour C between the annular protrusion 135 of the latch 130 and the annular gasket 160A is a closed annulus, and the latch 130 is in a first position relative to the cover 120. In Figure 10B, the contact contour C between the annular protrusion 135 of the latch 130 and the annular gasket 160A is a non-closed annulus (e.g., C-shaped), and the latch 130 is in a second position relative to the cover 120. In Figure 11, the latch 130 is in the second position relative to the cover 120. As shown in Figure 11, when the latch 130 moves from the first position to the second position relative to the cover 120, such that a portion of the annular protrusion 135 crosses the second perforation 162 of the annular gasket 160A, this portion of the annular protrusion 135 will not be able to make airtight contact with the annular gasket 160A, thereby forming a gap channel that allows gas in the internal space S to flow with external gas along the path indicated by the dashed double arrows in Figure 11. This allows the airtightness to be released in the initial stage of opening the cover (e.g., before the latch 130 has moved to the second position relative to the cover 120), thus helping to reduce the difficulty of opening the cover.
[0045] From the detailed description of the specific embodiments disclosed above, it is clear that, according to the waterproof housing disclosed herein, during the lateral movement of the latch relative to the cover by moving the latching block, the second abutment of the latching member abuts against the first abutment of the base, causing the cover to rise relative to the base. This allows one side of the cover to tilt upwards, creating a gap with the base and releasing the airtightness between the base and the cover, facilitating further removal of the cover by the user. After one side of the cover rises relative to the base, a pushing mechanism located between the base and the cover assists in pushing the cover upwards, ensuring that the cover can smoothly spring up after the airtightness is released, reducing the need for manual operation by the user. During the lateral movement of the latching member relative to the cover, by switching the contact profile between the annular protrusion of the latching member and the annular gasket located on the cover from a closed ring to a non-closed ring, the airtightness can be released in the initial stage of opening the cover, without waiting for the latching member to fully displace, thereby helping to reduce the difficulty of opening the cover.
[0046] Although the present disclosure has been described above with reference to embodiments, it is not intended to limit the present disclosure. Anyone 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.
