The invention is not limited thereto.

[0027] FIG. 5 is a partial cross-sectional schematic view of the computer apparatus of the embodiment of FIG. 1. Please refer to FIG. 3 and FIG. 5. In the embodiment, the host unit 110 has at least one host guide portion 114, the display unit 120 has at least one display guide portion 124, and the at least one display guide portion 124 corresponds to the at least one host guide portion 114. Specifically, the host unit 110 has a plurality of host guide portions 114, for example three host guide portions 114. The display unit 120 has a plurality of display guide portions 124, for example three display guide portions 124. The host guide portions 114 and the display guide portions 124 correspond to each other, so that the display bonding area A2 may be positioned to the host bonding area A1, and the display connector 122 is connected to the host connector 112. That is to say, when the user connects the host unit 110 and the display unit 120, the host guide portions 114 and the display guide portions 124 may guide the user to move the host unit 110 and the display unit 120 to a suitable position. This way, the display bonding area A2 may be positioned to the host bonding area A1, and the display connector 122 may be connected to the host connector 112.

[0028] Referring to FIG. 5, in the embodiment, the host guide portion 114 includes a guide pillar 114a and an elastic element 114b. The display guide portion 124 is, for example, a guide opening. Specifically, the guide pillar 114a and the elastic element 114b are disposed on the outer casing 116. The elastic element 114b is disposed between the guide pillar 114a and the host unit 110. When the guide pillar 114a is not located at the corresponding position relative to the display guide portion 124, the guide pillar 114a is blocked by the outer casing 126 to compress the elastic element 114b. At this point, the guide pillar 114a and the compressed elastic element 114b are both located in the space that the elastic element 114b was in prior to be compressed. This way, the guide pillar 114a does not protrude out the surface of the outer casing 116 facing the display unit 120. In addition, when the guide pillar 114a is located at the corresponding position relative to the display guide portion 124, the guide pillar 114a is pushed by the elastic element 114b to enter the display guide portion 124 and restrict the movement, for example, movement along the direction of the second axis Y and the third axis Z, of the outer casing 116 on the surface of the display unit 120. In the embodiment, when the guide portions 114a of the host unit 110 have all respectively entered the display guide portions 124 of the display unit 120, the guide pillars 114a restrict the movement and rotation of the outer casing 116 on the surface of the display unit 120. For example, the movement along the directions of the second axis Y and the third axis Z, and the rotation on the direction of the first axis X are limited. At this point, the host unit 110 and the display unit 120 are both in suitable positions, and the display bonding area A2 is positioned to the host bonding area A1, and the display connector 122 is connected to the host connector 112. In other embodiments, the host guide portions 114 and the display guide portions 124 also may be other types of guide components, the invention is not limited thereto.

[0029] Furthermore, in the embodiment, the display bonding area A2 may be slightly recessed. When the user attempts to connect the host unit 110 and the display unit 120, the slightly recessed display bonding area A2 may guide the user to position the display bonding area A2 to the host bonding area A1 faster. In other embodiments, the computer apparatus 100 may also have other positioning mechanisms, to assist in positioning the display bonding area A2 to the host bonding area A1, the invention is not limited thereto.

[0030] Referring to FIG. 3, in the embodiment, the computer apparatus 100 further includes at least one locking element 140. When the display bonding area A2 is positioned to the host bonding area A 1 and the display connector 122 is coupled to the host connector 112, the locking unit 140 is adapted to lock the host unit 110 to the display unit 120. Specifically, the computer apparatus 100 for example, includes a plurality of locking elements 140. The locking elements 140 are, for example, a plurality of screws. Each of the screws (locking elements 140) penetrates a screw hole 142 located in the outer casing 116 and a screw hole 144 located in the outer casing 126, so that the host unit 110 is locked to the display unit 120. However, the invention does not limit the actual locking method of the locking element 140. In the embodiment, the user connects the host unit 110 and the display unit 120, and after the display connector 122 is connected to the host connector 112, the locking elements 140 are then used to lock the host unit 110 to the display unit 120.

[0031] In the embodiment, the display bonding area A2 may be positioned to the host bonding area A 1 and the display connector 122 is connected to the host connector 112. In addition, the display unit 120 is detachably connected to the host unit 110. Thus, when the display unit 120 or the host unit 110 is damaged, the display unit 120 or the host unit 110 may be individually removed or replaced. For example, when the computer apparatus 100 malfunctions and the maintenance person (or user) does not know if the host unit 110 or the display unit 120 has malfunctioned, the maintenance person (or user) may separate the host unit 110 from e display unit 120. Then each may be respectively inspected, to quickly determine whether the host unit 110 or the display unit 120 has malfunctioned. In addition, the maintenance person (or user) may individually remove the display unit 120 or the host unit 110, and replace it with a spare, so that when a malfunction occurs, the entire computer apparatus 100 does not have to be returned to the factory maintenance. At the same time, the malfunctioned and removed display unit 120 or host unit 110 may perform further processes such as being inspected more in depth, fixed, or scrapped. Thus, the maintenance person (or user) may individually replace the malfunctioned display unit 120 or the malfunctioned host unit 110, so that the user may continue using the computer apparatus 100. This way, the computer apparatus 100 with an AIO framework is more convenient when undergoing maintenance.

[0032] FIG. 6 is a schematic view of the display unit of the computer apparatus of the embodiment of FIG. 1 being individually changed. Please refer to FIG. 6. In the embodiment, when the user has different requirements for the display unit or the hardware of the host unit, the user may individually replace or upgrade one of the display unit 120 or the host unit 110. The entire computer apparatus 100 does not need to be changed or upgraded. For example, when the user wants to use a display unit 120′ with bigger dimensions to replace the display unit 120 with smaller dimensions, the user may individually remove the display unit 120 originally connected to the host unit 110. Then, the user may position the display bonding area A2′ of the display unit 120′ to the host bonding area A1, and the display connector 122′ of the display unit 120′ is connected to the host connector 112. This way, the display unit 120′ is connected to the host unit 110. Similarly, when the user wants to replace the original host unit 110 with another host unit having better specifications, or the user wants to replace the original display unit 120 with another display unit having better specifications, the user may use a similar method to individually upgrade and replace one of the display unit 120 or the host unit 110. Thus, the computer apparatus 100 with an AIO framework is easy to upgrade and customize its hardware.

[0033] FIG. 7A to FIG. 7G are schematic views of a process of changing an angle of the display unit relative to the host unit according to another embodiment of the invention. Please refer to FIG. 7A to FIG. 7G. In the embodiment, the shapes of the host bonding area A1 and the display bonding area A2 are regular polygons with an even number of sides, such as four sides. In addition, the shape of the position concave portion PR corresponds to the shape of the host bonding area A1. The shape of the concave of the position frame PS corresponds to the shape of the position concave portion PR. In the embodiment, the shape of the position concave portion PR and the shape of the position frame PS are, for example, regular polygons with four sides. The position frame PS is matched the position concave portion PR to be in a first position or a second position. This way, an angle of the host connector 112 relative to the host unit 110 is changed from a first angle corresponding to the first position to a second angle corresponding to the second position. It should be noted that, in some embodiments, the shape of the host bonding area A1 may be designed according to the shape of the outer casing 116, with suitable trimming, chamfering, or filleting. At the same time, the shape of the display bonding area A2 corresponds to the shape of the host bonding area A1. The invention is not limited thereto.

[0034] In particular, the user may change an angle of the display unit 120 relative to the host unit 110 according to user requirements. In the embodiment, the display unit 120 being rotated relative to the host unit 110 may be described in the following schematic process diagrams. First, referring to FIG. 7A and FIG. 7B, after unlocking the locking element 140 locking the host unit 110 to the display unit 120, the display unit 120 (along with the outer casing) and the host unit 110 (along with the outer casing) are separated from each other in opposite directions along the first axis X (separated as shown in FIG. 7B). Next, referring to FIG. 7B and FIG. 7C, the display unit 120 is rotated an angle, for example 90 degrees (after rotation as shown in FIG. 7C) relative to the host unit 110. For example, a long side of the display unit 120 was originally parallel to the second axis Y, and after being rotated, the long side of the display unit 120 is, for example, parallel to the third axis Z. In addition, the display connector 122 is also rotated 90 degrees with the display unit 120 relative to the host unit 110.

[0035] Next, referring to FIG. 7C and FIG. 7D, the position frame PS (along with the host connector 112) is removed from the position concave portion PR in an opposite direction along the first axis X (removed as shown in FIG. 7D). Prior the position frame PS being removed from the position concave portion PR, the position frame PS is disposed in the position concave portion PR in a first position, and the host connector 112 has a first angle corresponding to the first position relative to the host unit 110. The first angle is, for example, 0 degrees (i.e. the host connector 112 has not been rotated yet).

[0036] Next, referring to FIG. 7D and FIG. 7E, the position frame PS is rotated an angle, for example 90 degrees (as shown in FIG. 7E). Next, referring to FIG. 7E and FIG. 7F, the position frame PS is disposed in the position concave portion PR in a direction along the first axis X. Since the shape of the position concave portion PR and the shape of the concave of the position frame PS are both regular polygons with four sides, thus when the position frame PS is rotated 90 degrees, the position frame PS is still able to be successfully disposed in the position concave portion PR (as seen in FIG. 7F). At this point, the position frame PS is disposed in the position concave portion PR in a second position, and the host connector 112 has a second angle corresponding to the second position relative to the host unit 110. The second angle is, for example 90 degrees (the host connector 112 is rotated 90 degrees relative to the host unit 110). Next, referring to FIG. 7F and FIG. 7G, the display unit 120 moves in a direction along the first axis X, so that the display connector 122 is connected again with the host connector 112, and the display unit 120 is connected with the host unit 110 again (shown in FIG. 7G). In particular, an angle of the display unit 120 relative to the host unit 110 is changed to an angle of 90 degrees. In addition, since the display connector 122 is rotated 90 degrees because the display unit 120 is rotated relative to the host unit 110, thus, the display connector 122 and the host connector 112 may still successfully connect, so that the display unit 120 and the host unit 110 maintain and electrical connection.

[0037] In other embodiments, the shapes of the host bonding area A1 and the display bonding area A2 may be other regular polygons with regular polygons with an even number of sides, circles, or other shapes. Since the shape of the position concave portion PR and the shape of the concave of the position frame PS correspond to the shape of the host bonding area A1, thus when the position frame PS is rotated an angle, the position frame PS may still be successfully disposed in the position concave portion PR. In addition, in these embodiments, suitable shapes may be adapted for the host bonding area A1 and the display bonding area A2, so that the display unit 120 may be rotated other angles relative to the host unit 110, the invention is not limited thereto. Furthermore, in these embodiments, the shape of the position concave portion PR and the shape of the position frame PS may be shapes that do not correspond with the shape of the host bonding area A1. However, in the embodiments, the shape of the position concave portion PR and the shape of the concave of the position frame PS may be regular polygons with regular polygons with an even number of sides, circles, or other shapes, so that when the position frame PS is rotated an angle, the position frame PS still is successfully disposed in the position concave portion PR. To be specific, in the embodiments, through the above methods, the display unit 120 may be rotated relative to the host unit 110. For example, the user may rotate the display unit 120 in 90 degrees with respect to the host unit 110 according to user requirements, so that the originally horizontal display unit 120 is changed to vertical. Thus, the computer apparatus 100 has many applications.

[0038] Furthermore, in other embodiments, the display unit 120 may have a position frame and a position concave portion, and the display connector 122 is disposed on the position frame. In the embodiment, the position frame and the position concave portion of the display unit 120 is similar to the position frame PS and the position concave portion PR of FIG. 3 and FIG. 4. In addition, the position frame of the display unit 120 may correspond with the position concave portion of the display unit 120 to be at a first position or a second position. This way, an angle of the display connector 122 relative to the display unit is changed from a first angle corresponding to the first position to a second angle corresponding to the second position. In detail, the display connector 122 of the embodiments may use similar methods to the host connector 112 in FIG. 7A to FIG. 7G, so that when the display unit 120 is rotated an angle relative to the host unit 110, the host connector 112 is still connected with the display connector 122, so that the display unit 120 and the host unit 110 are electrically connected.

[0039] To sum up, the embodiments of the invention have at least one of the following advantages or effects. In the computer apparatus of the embodiment of the invention, the display bonding area may be positioned to the host bonding area, and the display connector is coupled to the host connector. In addition, the display unit is detachably connected to the host unit. Thus, when the display unit or the host unit is damaged, the display unit or the host unit may be individually changed, so that the computer apparatus with an AIO framework may undergo maintenance conveniently. In addition, the user may individually select the display unit or the host unit to undergo an upgrade or change according to user requirements. The entire computer apparatus does not need to be changed or upgraded. Thus, the computer apparatus with an AIO framework is easy to upgrade and customize its hardware. Furthermore, in an embodiment of the invention, the display unit of the computer apparatus may be rotated an angle relative to the host unit, so that the computer apparatus may have multiple applications.
