As shown in FIG. 1A and FIG. 1B, the electronic apparatus applies the display module 1 of the invention can be, but not limited to, a portable computer apparatus (e.g. a notebook computer, a tablet computer, and etc.) or a handheld electronic apparatus (e.g. PDA, mobile phone, game console, and etc.). In other words, the electronic apparatus applies the display module 1 of the invention can be any electronic product having a display. Electronic apparatuses that have the requirement of not exposing screws out of the displays can apply the concepts of the display module 1 disclosed by the invention to hide screws.
As shown in FIG. 1A and FIG. 1B, the display module 1 of the embodiment can include a front frame 10, a resilient member 12, a rear housing 14, a glass panel 16, and a hinge device 18. A part of the resilient member 12 is detachably engaged with the front frame 10. The rear housing 14 is also engaged with the front frame 10. The glass panel 16 is fixed to the front frame 10. For example, if an electronic apparatus is a notebook computer having flat display module attached with glass, the foregoing rear housing 14 can be the rear housing of the notebook computer, the foregoing front frame 10 can be the front frame of the notebook computer, and the hinge device 18 can be the hinge that pivotally connects the rear housing and the front frame to the host of the notebook computer. The structures and functions of all components of the display module 1 in the embodiment will be described in detail as followed.
Please refer to FIG. 2. FIG. 2 is an enlarged view showing the display module 1 near the corner 100c of the frame body 100 in FIG. 1A, wherein the pulling portion 120c separates from the circular groove 102 to expose the first disassembly hole 104.
As shown in FIG. 2, the front frame 10 in the display module 1 of the embodiment can further include a frame body 100, a circular groove 102, and a first disassembly hole 104. The circular groove 102 can be formed along a periphery of the frame body 100. The first disassembly hole 104 can be located in the circular groove 102. A part of the resilient member 12 is detachably engaged in the circular groove 102, so as to cover the first disassembly hole 104 in the circular groove 102. In the embodiment, the frame body 100 of the front frame 10 can further include an external wall 100a and a bearing portion 100b. The circular groove 102 of the front frame 10 can be located between the external wall 100a and the bearing portion 100b of the frame body 100. Therefore, the bearing portion 100b of the frame body 100 can be used to bear the glass panel 16 and fix the glass panel 16. In other words, when the glass panel 16 is fixed to the bearing portion 100b of the frame body 100, the resilient member 12 that is engaged in the circular groove 102 of the front frame 10 is also located between the external wall 100a of the frame body 100 and the glass panel 16. Of course, the first disassembly hole 104 is not necessary to be entirely located in the circular groove 102. In an embodiment, the first disassembly hole 104 can be partially located in the circular groove 102 and partially located on the bearing portion 100b of the frame body 100. Accordingly, the resilient member 12 can covers the part of the first disassembly hole 104 that is located in the circular groove 102, and the glass panel 16 can covers the part of the disassembly hole 104 that is located on the bearing portion 100b of the frame body 100.
As shown in FIG. 2, the resilient member 12 in the display module 1 of the embodiment can further include a buffer portion 120a and clamped portions 120b. The buffer portion 120a of the resilient member 12 is detachably engaged in the circular groove 102 and is located between the external wall 100a of the frame body 100 and the glass panel 16, so as to be used for covering the first disassembly hole 104. The clamped portions 120b of the resilient member 12 and the buffer portion 120a are connected to each other. The clamped portions 120b can be clamped between the glass panel 16 and the bearing portion 100b of the frame body 100, so as to prevent the resilient member 12 totally separating from the circular groove 102. The quantity of the clamped portions 120b of the resilient member 12 is not limited and can be adjusted according to the requirements of designing or restrictions of manufacturing.
Furthermore, the frame body 100 of the front frame 10 in the embodiment has a corner 100c. The first disassembly hole 104 of the front frame 10 can be located in the circular groove 102 and near the corner 100c of the frame body 100. The buffer portion 120a of the resilient member 12 can further include a pulling portion 120c. In another word, the pulling portion 120c is the part of the buffer portion 120a that is near the corner 100c and between the doted lines in FIG. 2. The pulling portion 120c of the buffer portion 120a is detachably engaged in the circular groove 102 and near the corner 100c for covering the first disassembly hole 104. Besides, the pulling portion 120c of the buffer portion 120a can be interconnected between two clamped portions 120b. Thus, during the operation of pulling the pulling portion 120c located at the corner 100c of the frame body 100 to separate from the circular groove 102, the resilient member 12 will not be pulled to entirely separate the circular groove 102 because the two clamped portions 120b connecting to the pulling portion 120c of the buffer portion 120a are clamped between the glass panel 16 and the bearing portion 100b of the frame body 100. Generally, the shape of a notebook computer is rectangular. That is to say, the front frame of the notebook computer substantially has four corners. Therefore, if the convenience of disassembly is concerned, the pulling portion 120c of the buffer portion 120a can be, but not limited to, selectively formed at the left upper corner or the right upper corner. That is to say, the quantities of the first disassembly hole 104 and the clamped portions 120b of the resilient member 12 are not limited and can be adjusted according to the requirements of designing or restrictions of manufacturing.
In the embodiment, the buffer portion 120a of the resilient member 12 can be circular. The circular groove 102 can be, but not limited to, adapted to entirely accommodate the buffer portion 120a of the resilient member 12 (as shown in FIG. 1A and FIG. 1B), and the buffer portion 120a of the resilient member 12 is located between the external wall 100a of the frame body 100 and the glass panel 16. For example, there can also be a plurality of resilient members disposed in the circular groove 102, as long as the resilient members can achieve the functions and goals of buffering between the external wall 100a of the frame body 100 and the glass panel 16 and covering the first disassembly hole 104 in the circular groove 102.
Please refer to FIG. 3 and FIG. 4. FIG. 3 is an enlarged view showing the rear housing 14 and the front frame 10 in FIG. 1A, wherein the trimming board 146 has not engaged with the housing body 140, and the first fastening member 20 has not been fastened in the first assembly hole 142. FIG. 4 is a section view showing the rear housing 14 and the front frame 10 in FIG. 3 along the line 4-4, wherein the trimming board 146 has engaged with the housing body 140, and the first fastening member 20 has been fastened in the first assembly hole 142.
As shown in FIG. 3 and FIG. 4, the rear housing 14 in the display module 1 of the embodiment can further include a housing body 140, a first assembly hole 142, a second disassembly hole 144, a trimming board 146, and an opening groove 148. The housing body 140 of the rear housing 14 and the frame body 100 of the front frame 10 can be engaged to each other. The first assembly hole 142 of the rear housing 14 can be located on the housing body 140. The second disassembly hole 144 can also be located on the housing body 140. The trimming board 146 of the rear housing 14 and the housing body 140 can be engaged to each other. Furthermore, the trimming board 146 of the rear housing 14 can further include a longer first engagement structure 146b and a shorter engagement structure 146c. During the operation of engaging the trimming board 146 of the rear housing 14 to the housing body 140, the first engagement structure 146b of the trimming board 146 can be engaged into the opening groove 148 before engaging the second engagement structure 146c to the housing body 140. Thus, the trimming board 146 of the rear housing 14 can be used to cover the first assembly hole 142 and the second disassembly hole 144. Besides, the first fastening member 20 can be used for fastening the rear housing 14 to the front frame 10 through the first assembly hole 142. It can be seen that after the first fastening member 20 is fastened to the rear housing 14, the trimming board 146 engaged with the rear housing 14 can hide the first fastening member 20. In other words, no fastening member will be seen on the appearance of the rear housing 14, and the goal of the invention to hide screws can be achieved. In the embodiment, the foregoing first fastening member 20 can be, but not limited to, a screw. For example, the foregoing first fastening member 20 can also be a bolt, a pin, or other fastening member that has equivalent fastening effect.
Please refer to FIG. 5A and FIG. 5B. FIG. 5A is a section view showing the rear housing 14 and the front frame 10 in FIG. 3 along the line 5A-5A, wherein the trimming board 146 has not separated from the housing body 140. FIG. 5B is another section view showing the rear housing 14 and the front frame 10 in FIG. 5A, wherein the trimming board 146 has separated from the housing body 140.
As shown in FIG. 5A and FIG. 5B, the first disassembly hole 104 located in the circular groove 102 of the front frame 10 and the second disassembly hole 144 of the rear housing 14 are communicated to each other. Therefore, under the condition that the trimming board 146 is engaged with the housing body 140 to cover and hide the first fastening member 20 fastened to the housing body 140, firstly the pulling portion 120c of the resilient member 12 can be pulled to separate from the circular groove 102 and thus to expose the first disassembly hole 104 (as shown in FIG. 2) as long as the first fastening member 20 is desired to be disassembled to separate the rear housing 14 from the front frame 10 (as shown in FIG. 5A). Afterwards, because the first disassembly hole 104 in the circular groove 102 of the front frame 10 and the second disassembly hole 144 of the rear housing 14 communicate to each other, the trimming board 146 engaged to the rear housing 14 can be pushed away from the housing body 140 through the first disassembly hole 104 of the front frame 10 and the second disassembly hole 144 of the rear housing 14 by any long and thin disassembly tool, such as a pin, a needle, a toothpick, and etc. So, the first fastening member 20 that is fastened in the first assembly hole 142 of the housing body 140 can be exposed and disassembled.
In the embodiment, in order to prevent the trimming board 146 engaged to the housing body 140 from unpredictably moving relative to the housing body 140, the trimming board 146 can further include a support pillar 146a. The support pillar 146a of the trimming board 146 is capable of passing through the second disassembly hole 144 of the housing body 140. Accordingly, after the trimming board 146 is engaged to the housing body 140, the support pillar 146a that is inserted into the second disassembly hole 144 can improve the positioning capability of the trimming board 146 relative to the housing body 140. Moreover, because the support pillar 146a of the trimming board 146 is inserted into the second disassembly hole 144 of the housing body 140, the disassembly tool for pushing the trimming board 146 away from the housing body 140 is unnecessarily too long, so as to decrease the time to find a proper disassembly tool and increase the convenience of disassembling the trimming board 146.
According to the foregoing recitations of the embodiments of the invention, it is obvious that the display module of the invention mainly includes following advantages. In order to achieve the design of hiding screws of the display module, the screw for fastening the rear housing to the front frame can be hid by the trimming board engaged on the rear housing. Besides, in order to disassemble the screw on the rear housing, the display module of the invention further includes a hidden disassembly hole on the front frame. The trimming board can be pushed apart from the rear housing through the disassembly hole, so as to expose the screw on the rear housing and thus the screw can be disassembled.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims.
