Description

TECHNICAL FIELD

[0001] The utility model relates to a device shell and electronic device, especially a device shell and electronic device containing foot pad. BACKGROUND

[0002] A notebook computer usually comprises a main body and a display body which is pivoted to the main body by a pivot. In recent years, in order to effectively cool various heat sources in the main body, some manufacturers design the bottom cover of the main body to be connected with the pivot, so that the bottom cover is moved when the notebook computer is opened to increase the heat dissipation space.

[0003] However, when the user needs to use the notebook computer in a quiet environment, the bottom cover connected with the pivot will inevitably transmit the noise generated by the fan while increasing the heat dissipation space. In addition, such design also requires the entire bottom cover to be removed in order to maintain the main body. Therefore, the conventional design of connecting the bottom cover with the pivot has the problems of insufficient flexibility and inconvenience in maintenance. SUMMARY

[0004] The utility model discloses a device shell and electronic device to improve the flexibility of the device shell and make the maintenance of the elements in the device shell more convenient.

[0005] The device shell disclosed by an embodiment of the utility model comprises a base, two foot pads and a bottom cover. The two foot pads protrude from the same side of the base and are separated from each other. Each of the two foot pads has at least one sliding groove. In each of the two foot pads, the at least one sliding groove comprises a first horizontal section, a bent section and a second horizontal section. The bent section connects the first horizontal section and the second horizontal section. The first horizontal section and the second horizontal section are parallel to each other, and the second horizontal section is farther away from the base than the first horizontal section. The opposite sides of the bottom cover are respectively and slidably arranged in the at least one sliding groove of the two foot pads.

[0006] According to one embodiment of the present disclosure, the base has a receiving groove, the bottom cover comprises a low-noise position, an efficient heat dissipation position and a maintenance position, when the bottom cover is located at the low-noise position, the bottom cover is located at one end of the first horizontal section away from the bent section and covers the receiving groove, when the bottom cover is located at the efficient heat dissipation position, the bottom cover is located at one end of the second horizontal section close to the bent section, and the bottom cover exposes part of the receiving groove, when the bottom cover is located at the maintenance position, the bottom cover is located at one end of the second horizontal section away from the bent section, and the bottom cover exposes more part of the receiving groove than when the bottom cover is located at the efficient heat dissipation position.

[0007] According to one of the embodiments of the present disclosure, a positioning device is further included, which is slidably arranged on the base and located on one side of the bottom cover. The positioning device has at least one first positioning structure, and the one side of the bottom cover has at least one second positioning structure. The at least one first positioning structure and the at least one second positioning structure are a convex column and a concave groove matched with each other. When the bottom cover is located at the low-noise position, the at least one first positioning structure and the at least one second positioning structure are positioned with each other.

[0008] According to one of the embodiments of the present disclosure, a positioning device is further included, which is located on one side of the bottom cover and includes a movable seat, an elastic element and a stop protrusion. The movable seat is movably arranged on the base through the elastic element. The stop protrusion protrudes from the side of the movable seat away from the elastic element. The bottom cover has a clamping protrusion protruding towards the accommodating groove. When the bottom cover is located at the high-efficiency heat dissipation position, the stop protrusion is stopped on one side of the clamping protrusion to position the bottom cover at the high-efficiency heat dissipation position.

[0009] According to one of the embodiments of the present disclosure, a positioning device is further included. The base further has an assembly groove separated from the accommodating groove. The positioning device includes an operation part and at least one clamping part connected with each other. The operation part is slidably arranged in the assembly groove. The bottom cover has at least one clamping protrusion protruding towards the accommodating groove. The at least one clamping part is detachably clamped with the at least one clamping protrusion of the bottom cover.

[0010] According to one of the embodiments of the present disclosure, the number of the at least one sliding groove of each of the two foot pads is a plurality. In each of the two foot pads, a plurality of sliding grooves are separated from each other. The opposite sides of the bottom cover are slidably arranged in the plurality of sliding grooves of the two foot pads, respectively.

[0011] Another embodiment of the electronic device includes a device housing, a mainboard assembly and a fan. The device housing includes a base, two foot pads and a bottom cover. The two foot pads protrude from the same side of the base and are separated from each other. Each of the two foot pads has at least one sliding groove. In each of the two foot pads, the at least one sliding groove includes a first horizontal segment, a bent segment and a second horizontal segment. The bent segment connects the first horizontal segment and the second horizontal segment. The first horizontal segment and the second horizontal segment are parallel to each other. The second horizontal segment is farther away from the base than the first horizontal segment. The opposite sides of the bottom cover are slidably arranged in the at least one sliding groove of the two foot pads, respectively. The mainboard assembly is arranged in the base. The fan is arranged in the base and electrically connected to the mainboard assembly.

[0012] According to the device housing and electronic device disclosed in the above embodiments, since the opposite sides of the bottom cover are slidably disposed in the grooves of the foot pads, and the grooves include a first horizontal section, a bent section, and a second horizontal section farther from the base than the first horizontal section, the bottom cover can slide independently in the first horizontal section, the bent section, and the second horizontal section of the groove without being restricted by other components (such as pivot members disposed on the device housing). This improves the flexibility of the device housing in use.

[0013] Furthermore, by incorporating the sliding groove into the foot pad, the bottom cover can be slidable with a simpler structure, making the sliding operation of the bottom cover easier. This allows the bottom cover to be moved more conveniently to a position where components inside the device housing can be repaired. In addition, this invention designs the sliding groove into the existing structure (i.e., the foot pad) within the device housing. This avoids occupying additional installation space in the device housing, thus meeting the requirement for a thinner device housing. Attached Figure Description

[0055] The detailed features and advantages of the embodiments of the present application are described in detail in the embodiments below, which are sufficient for anyone with ordinary knowledge in the art to understand the technical content of the embodiments of the present application and to implement them, and according to the content disclosed in the specification, claims and drawings, those skilled in the art can easily understand the related purposes and advantages of the present application. The following embodiments further illustrate the ideas of the present application, but do not limit the scope of the present application in any way.

[0056] Please refer to Figures 1 to 5 . Figure 1 is a perspective view of an electronic device according to an embodiment of the present application. Figure 2 is Figure 1 a perspective view of a bottom cover of a device housing of the electronic device in Figure 3 is Figure 1 a side cross-sectional view of the bottom cover of the device housing of the electronic device in Figures 4 to 6 is Figure 3 a cross-sectional view of the electronic device in

[0057] In the present embodiment, the electronic device 10 is, for example, a main housing of a notebook computer, and includes a device housing 100, a mainboard assembly 300, and a fan 400.

[0058] In the present embodiment, the device housing 100 includes, for example, a base 110, two foot pads 120, a bottom cover 130, a positioning device 140, a positioning device 150, and a positioning device 160. As shown in Figure 1 , the positioning devices 140, 150, 160 are disposed, for example, on three adjacent sides of the base 110. In addition, the positioning devices 140, 150, 160 are disposed, for example, on three adjacent sides of the bottom cover 130. The positioning devices 150, 160 are disposed on opposite sides of the bottom cover 130. It should be noted that in other embodiments, the positioning device 150 or the positioning device 160 can be disposed on both opposite sides of the bottom cover.

[0059] The base 110 has a receiving groove 111 and an assembly groove 112 separated from each other. The mainboard assembly 300 and the fan 400 are located in the receiving groove 111. The fan 400 is electrically connected to the mainboard assembly 300.

[0060] Two foot pads 120 protrude from the same side of the base 110 and are separated from each other. Each foot pad 120 has a plurality of grooves 121 that are separated from each other. These grooves 121 of each foot pad 120 have similar structures. Therefore, one groove 121 of one of the foot pads 120 will be described by way of example below. The groove 121 includes a first horizontal segment 122, a bent segment 123 and a second horizontal segment 124. The bent segment 123 connects the first horizontal segment 122 and the second horizontal segment 124. The first horizontal segment 122 and the second horizontal segment 124 are parallel to each other. The second horizontal segment 124 is further away from the base 110 than the first horizontal segment 122.

[0061] like Figure 3 As shown, the opposite sides of the bottom cover 130 are slidably disposed in the grooves 121 of the two foot pads 120 via a plurality of guide posts 200. It should be noted that, in this embodiment, each of the two foot pads 120 includes, for example, two grooves 121. Correspondingly, each of the opposite sides of the bottom cover 130 has two guide posts 200, so that the bottom cover 130 can slide more stably through the cooperation of the guide posts 200 and the grooves 121. However, in other embodiments, if the size of the bottom cover is small, each foot pad may also include only one groove.

[0062] like Figures 2 to 4 As shown, in this embodiment, the positioning device 140 includes an operating part 141 and two latching parts 142 connected to each other. The operating part 141 is slidably disposed in the assembly groove 112. The bottom cover 130 has two latching protrusions 131 protruding toward the receiving groove 111. The two latching parts 142 are detachably engaged with the two latching protrusions 131 respectively.

[0063] like Figure 1 and Figure 5 As shown, the positioning device 150 is slidably disposed on the base 110. The positioning device 150 has a plurality of first positioning structures 151. One side of the bottom cover 130 has a plurality of second positioning structures 132. These first positioning structures 151 and these second positioning structures 132 are, for example, mutually matching protrusions and grooves. However, in other embodiments, the forms of the first positioning structures and the second positioning structures can also be interchanged, with grooves and protrusions respectively. Furthermore, in other embodiments, the number of both the first positioning structure and the second positioning structure may be one.

[0064] like Figures 1 to 3 and Figure 6As shown, the positioning device 160 includes a movable seat 161, a resilient element 162, and a stop protrusion 163. The movable seat 161 is movably disposed on the base 110 by the resilient element 162. The resilient element 162 is, for example, a spring. The stop protrusion 163 protrudes from a side of the movable seat 161 away from the resilient element 162. The bottom cover 130 has a clamping protrusion 133 protruding toward the accommodating groove 111. The clamping protrusion 133 has, for example, a first guide inclined surface 134. The stop protrusion 163 has, for example, a second guide inclined surface 164. The clamping protrusion 133 corresponds to the stop protrusion 163, and the first guide inclined surface 134 corresponds to the second guide inclined surface 164.

[0065] In this embodiment, the bottom cover 130 includes, for example, a low-noise position, a high-efficiency heat dissipation position, and a maintenance position. First, as shown in Figure 1 and Figure 3 shown, when the bottom cover 130 is located at the low-noise position, the guide column 200 of the bottom cover 130 is located at an end of the first horizontal section 122 away from the bent section 123, and the bottom cover 130 shields the accommodating groove 111. In this way, the noise transmitted from the fan 400 to the outside of the device housing 100 can be reduced.

[0066] In addition, as shown in Figure 1 , the two magnets 211 fixed to the bottom cover 130 are respectively attracted to the two magnets 212 fixed to the base 110, so as to position the bottom cover 130 at the low-noise position.

[0067] In addition, as shown in Figure 4 , when the bottom cover 130 is located at the low-noise position, the operation portion 141 is located at the clamping position so that the two clamping hook portions 142 are respectively engaged with the two clamping protrusions 131, so as to position the bottom cover 130 at the low-noise position. In addition, as shown in Figure 4 , when the operation portion 141 is located at the clamping position, the magnet 221 fixed to the operation portion 141 is separated from the magnet 222 fixed to the base 110.

[0068] In addition, as shown in Figure 5 , when the bottom cover 130 is located at the low-noise position, the first positioning structures 151 are respectively positioned with the second positioning structures 132, so as to position the bottom cover 130 at the low-noise position.

[0069] Please refer to Figures 7 to 11 . Figures 7 to 11 To present the actuation schematic diagram of moving the bottom cover in Figure 3 from the low-noise position to the high-efficiency heat dissipation position. In order to move the bottom cover 130 from the low-noise position to the high-efficiency heat dissipation position, as shown in Figure 7As shown, the operation portion 141 can be moved from the engaging position to the releasing position in the assembling groove 112 along a pulling direction Ml. In this way, the two engaging hook portions 142 are separated from the two engaging convex portions 131, respectively. In addition, as shown, Figure 7 As shown, when the operation portion 141 is located at the releasing position, the magnet 221 fixed on the operation portion 141 is attracted to the magnet 222 fixed on the base 110 to position the operation portion 141 at the releasing position. Then, as shown, Figure 8 As shown, the positioning device 150 can be pulled along a pulling direction M2 to separate the first positioning structures 151 from the second positioning structures 132, respectively.

[0070] Then, as shown, Figures 9 to 11 As shown, the bottom cover 130 can be moved from the low-noise position to the high-efficiency heat dissipation position along a sliding direction S. When the bottom cover 130 is located at the high-efficiency heat dissipation position, the guide post 200 of the bottom cover 130 is located at one end of the second horizontal section 124 close to the bending section 123, and the bottom cover 130 exposes part of the accommodating groove 111, and the bottom cover 130 is away from the base 110. In this way, the fan 400 has more space to dissipate heat for the mainboard assembly 300. In addition, as shown, Figure 11 As shown, when the bottom cover 130 is located at the high-efficiency heat dissipation position, the stop convex portion 163 is stopped at one side of the engaging convex block 133 to position the bottom cover 130 at the high-efficiency heat dissipation position.

[0071] In addition, as shown, Figure 9 As shown, when the bottom cover 130 is located at the high-efficiency heat dissipation position, the two magnets 231 fixed on the bottom cover 130 are repelled from the two magnets 232 fixed on the base 110 to provide a buffer feeling when the bottom cover 130 is moved from the low-noise position to the high-efficiency heat dissipation position, and to assist the bottom cover 130 to move from the high-efficiency heat dissipation position to the maintenance position.

[0072] In addition, as shown, Figure 9 As shown, when the bottom cover 130 is located at the high-efficiency heat dissipation position, a protective cover 240 can be arranged on the bottom cover 130 to shield the part of the accommodating groove 111 exposed by the bottom cover 130 to meet safety standards. The protective cover 240 can be arranged on the bottom cover 130 by a buckle structure 241, but is not limited thereto. In other embodiments, the protective cover can also be arranged on the bottom cover by magnetic attraction.

[0073] Please refer to Figures 12 to 14 . Figures 12 to 14 To present the actuation schematic diagram of moving the bottom cover in Figure 10 from the high-efficiency heat dissipation position to the maintenance position. In order to move the bottom cover 130 from the high-efficiency heat dissipation position to the maintenance position, as shown, Figure 12As shown, the movable seat 161 can be moved away from the bottom cover 130 in a certain direction M3. This will cause the locking protrusion 133 to disengage from the stop protrusion 163. Then, as... Figure 13 and Figure 14 As shown, the bottom cover 130 can be moved from the high-efficiency heat dissipation position to the maintenance position along the sliding direction S. When the bottom cover 130 is in the maintenance position, the bottom cover 130 is located at the end of the second horizontal segment 124 away from the bending segment 123, and the bottom cover 130 is positioned relative to the position in the high-efficiency heat dissipation position (e.g., ...). Figure 9 As shown, more of the receiving slot 111 is exposed. This makes it easier to repair or clean the motherboard assembly 300 or the fan 400.

[0074] In addition, such as Figure 13 As shown, when the bottom cover 130 is in the maintenance position, the two magnets 231 fixed to the bottom cover 130 will repel the two magnets 252 fixed to the base 110 respectively, so as to provide a cushioning feel when the bottom cover 130 is about to move from the high-efficiency heat dissipation position to the maintenance position, and assist the bottom cover 130 to return from the maintenance position to the high-efficiency heat dissipation position.

[0075] Please see Figure 15 . Figure 15 To present Figure 14 This diagram illustrates the movement of the bottom cover from the maintenance position back to the high-efficiency heat dissipation position or the low-noise position. When the bottom cover 130 moves from the maintenance position (e.g., ...) Figure 13 (As shown) Move to a location with high-efficiency heat dissipation (such as...) Figure 9 When (as shown), the first guide slope 134 of the locking protrusion 133 pushes against the second guide slope 164 of the stop protrusion 163, causing the movable seat 161 to move away from the bottom cover 130. In this way, the stop protrusion 163 can be moved out of place without additional operation of the movable seat 161.

[0076] According to the device housing and electronic device disclosed in the above embodiments, since the opposite sides of the bottom cover are slidably disposed in the grooves of the foot pads, and the grooves include a first horizontal section, a bent section, and a second horizontal section farther from the base than the first horizontal section, the bottom cover can slide independently in the first horizontal section, the bent section, and the second horizontal section of the groove without being restricted by other components (such as pivot members disposed on the device housing). This improves the flexibility of the device housing in use.

[0077] Furthermore, by incorporating the sliding groove into the foot pad, the bottom cover can be slidable with a simpler structure, making the sliding operation of the bottom cover easier. This allows the bottom cover to be moved more conveniently to a position where components inside the device housing can be repaired. In addition, this invention designs the sliding groove into the existing structure (i.e., the foot pad) within the device housing. This avoids occupying additional installation space in the device housing, thus meeting the requirement for a thinner device housing.

[0078] For example, the bottom cover can be located at one end of the first horizontal section away from the bending section (i.e. the low noise position) to cover the accommodation groove, so as to reduce the noise transmitted from the fan to the outside of the device housing; the bottom cover can be located at one end of the second horizontal section close to the bending section (i.e. the high heat dissipation position) to expose part of the accommodation groove, so that the fan has more space to dissipate heat for the mainboard assembly; the bottom cover can be located at one end of the second horizontal section away from the bending section (i.e. the maintenance position) to expose more part of the accommodation groove than when located at the high heat dissipation position, so as to facilitate maintenance of the mainboard assembly or the fan. Therefore, the device housing and the electronic device of the above-mentioned embodiments can at least provide the use flexibility considering the above three requirements.

[0079] Although the utility model discloses as above with the foregoing implementation examples, however, it is not used to limit the utility model, and the person skilled in the art can make some changes and decorations without departing from the spirit and scope of the utility model, therefore the patent protection scope of the utility model must be defined by the claims attached to the specification.
