Technical Field

The utility model relates to a casing especially relates to a casing that contains pin joint spare.

Background

Because the portable computer is currently being developed in a trend of being light and thin, the heat dissipation space in the portable computer is often limited. Generally, in order to enlarge the heat dissipation space of a portable computer, a conventional portable computer may include a pivotal cover in addition to a host body and a display body which are pivotally connected to each other. The pivoting type cover body is provided with a movable side and a pivoting side which are opposite to each other, and the pivoting side is pivoted to one side of the main machine body far away from the display machine body through a pivoting piece. Therefore, the movable side can be pivoted relative to the main body to be opened when the portable computer is operated, and the heat dissipation space of the portable computer is further expanded.

However, in order to maintain the pivotal connection between the cover and the main body, the pivotal side of the cover is still maintained at the original position when the movable side of the cover is pivoted and opened relative to the main body. That is, when the movable side of the cover body pivots relative to the main body to open, the pivoting side of the cover body does not move away from the main body, which makes it difficult for the pivoting cover body to effectively expand the heat dissipation space of the portable computer.

The first side plate 4021 stands on the first top plate 4020. The first top plate 4020 and the first side plate 4021 together enclose a sliding space 4023. The bottom plate 4028 is located on one side of the first side plate 4021 away from the first top plate 4020, and has two abdicating slots 40280. The two abdicating through grooves 40280 are communicated with the sliding space 4023, and the two bodies 4010 of the two pushed pieces 401 are respectively and separably located in the two abdicating through grooves 40280. Trace 450 is fixed to backplane 4028. One side of each protrusion 4022 is connected to the first top plate 4020 and the other side of each protrusion 4022 is connected to the first side plate 4021, and the two protrusions 4022 are located in the sliding space 4023.

Please refer to fig. 4 and 5. Fig. 4 is a side sectional view of the housing of fig. 1 in a first open state. Fig. 5 is an enlarged partial side view of the housing of fig. 4 shown in another cross-section.

When the first housing 100 is pivoted to the second housing 200 through the pivot 300 and opened along an opening direction a1, the first housing 100 drives the pushing component 402 to slide on the pushed component 401 along the sliding direction S1 through the pivot section 304 of the first assembling portion 301 of the pivot 300 and the transmission component 550, so that the inclined section 4025 of the pushing surface 4024 of the pushing component 402 pushes against the inclined section 4013 of the pushed surface 4012 of the pushed component 401. When the inclined section 4025 of the abutting surface 4024 abuts against the inclined section 4013 of the pressed surface 4012, the pressed member 401 is stopped by the stopper 405 and passes through the through hole 207 of the second housing 200, and further the movable plate 500 is driven to separate from the groove 205 of the second housing 200 and the vent 206 is exposed to the outside through the groove 205, so that the heat dissipation space of the housing 10 is effectively expanded. In addition, when the movable plate 500 is separated from the groove 205 of the second housing 200, the two stopper plates 4011 are stopped by the second housing 200 and the elastic element 404 is compressed by the mounting member 403 to store elastic potential energy. Furthermore, when the movable plate 500 is separated from the groove 205 of the second housing 200, the second bottom surface 502 of the movable plate 500 and the first bottom surface 201 of the second housing 200 are spaced apart from each other by a spacing distance D2. That is, the movable plate 500 is separated from the groove 205 of the second housing 200 in a parallel manner rather than a pivoting manner. In addition, in the embodiment, the protruding distance D1 of the foot pad 600 is greater than the spacing distance D2, that is, when the movable plate 500 is separated from the groove 205 of the second housing 200, the casing 10 is supported on the supporting surface by the foot pad 600, but not limited thereto. In other embodiments, the protruding distance of the foot pad may also be less than or equal to the spacing distance between the movable plate and the first bottom surface.

Please refer to fig. 6. Fig. 6 is a side sectional view of the housing of fig. 1 in a second open state.

When the first casing 100 is pivoted relative to the second casing 200 by the pivot 300 to further open along the opening direction a1 (i.e. the casing 10 is converted from the first open state to the second open state), the first casing 100 drives the abutting member 402 to slide on the pushed member 401 along the sliding direction S1 through the pivot section 304 of the first assembling portion 301 of the pivot 300 and the transmission assembly 550, so that the flat section 4026 of the abutting surface 4024 of the abutting member 402 abuts against the flat section 4014 of the pushed surface 4012 of the pushed member 401. When the flat section 4026 of the abutting surface 4024 abuts against the flat section 4014 of the pressed surface 4012, the movable plate 500 and the second housing 200 are kept at the same distance from each other (i.e., the second bottom surface 502 of the movable plate 500 and the first bottom surface 201 of the second housing 200 are kept at the separation distance D2).

Please refer to fig. 3 and fig. 4 again. When the first casing 100 is pivoted relative to the second casing 200 along a closing direction a2 opposite to the opening direction a1 by the hinge 300 to close (i.e. the casing 10 is converted from the first opening state or the second opening state to the closing state), the first casing 100 drives the pushing element 402 to slide on the pushed element 401 along a resetting direction S2 opposite to the sliding direction S1 by the hinge section 304 of the first assembling portion 301 of the hinge 300 and the transmission element 550. Moreover, the elastic element 404 compressed by the mounting member 403 releases the elastic potential energy to assist the pushed member 401 to drive the movable plate 400 to approach the groove 205 of the second housing 200 and to be accommodated in the groove 205 again.

In other embodiments, the linking component may also pass through the through hole of the second housing in other manners without including a limiting component. In addition, in other embodiments, if the housing is not required to be switched to the second open state, the pushing surface and the pushed surface may not include a flat section but only include an inclined section. In addition, in other embodiments, the pushed element does not need to include a stop plate, but a clamping groove is arranged on the pushed element and a clamping block is arranged on the second shell, and the body of the pushed element is stopped by the second shell through the clamping of the clamping groove and the clamping block.

It should be noted that, in other embodiments, the casing may not include a linking component connected to the pivot member through a transmission component, but only include two linking components connected to the two pivot members through two transmission components, and in such embodiments, the casing does not need to include a linking rod, and the two ventilation openings may be integrated into one ventilation opening. In still other embodiments, the housing may only include a pivot member, a transmission member and a linking member connected to each other. In other embodiments, the linking component may also include only one pushed element, and in such embodiments, the pushing element may also have only one pushing surface and the second housing may also have only one through hole.

In addition, the housing is not limited to include the foot pads disclosed in the above embodiments. Referring to fig. 7, fig. 7 is a schematic side sectional view of a housing according to another embodiment of the present invention. In this embodiment, the housing 10a does not include the foot pads disclosed in the above embodiments. When the movable plate 500a is separated from the groove 205a of the second housing 200a, the casing 10a is supported on the supporting surface only by the movable plate 500 a.

According to the casing disclosed in the above embodiment, since the gear fixed to the pivot section is engaged with the rack or is engaged with the rack through another gear rotatably disposed in the second casing, the pivot section can drive the pushing member to slide on the pushed member along the sliding direction through the gear and the rack. And because the normal direction of the pushing surface and the sliding direction have a first acute angle, and the normal direction of the pushed surface and the sliding direction have a second acute angle, when the pushing surface pushes the pushed surface, the pushed piece can pass through the through hole of the second shell, and then the movable plate is driven to be separated from the second shell, and the ventilation opening is exposed outside. Therefore, the whole movable plate can be spaced from the second shell to effectively enlarge the heat dissipation space of the shell.

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