The resilient member 16 is detachably engaged with the front frame 10 partially. The glass panel 20 can be 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 12 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. 2A, FIG. 2B, and FIG. 2C. FIG. 2A is an exploded view showing the display module 1 in FIG. 1A, wherein the trimming board 14 has not assembled with the front frame 10 and the rear housing 12. FIG. 2B is an enlarged view showing the display module 1 in FIG. 2A. FIG. 2C is another enlarged view showing the display module 1 in FIG. 2B.
As shown in FIG. 2A, FIG. 2B, and FIG. 2C, the front frame 10 in the display module 1 of the embodiment can include a frame body 100, a first positioning hole 102, and a clamping hole 104. The first positioning hole 102 and the clamping hole 104 of the front frame 10 are both located on the frame body 100. The rear housing 12 can include a housing body 120 and a second positioning hole 122. The housing body 120 of the rear housing 12 and the frame body 100 of the front frame 10 can be engaged to each other. The engaging type between the housing body 120 of the rear housing 12 and the frame body 100 can achieved by, but not limited to, hooks to lock to each other. And, after the housing body 120 of the rear housing 12 and the frame body 100 of the front frame 10 are engaged to each other, the second positioning hole 122 of the rear housing 12 is just communicated with the first positioning hole 102 of the front frame 10, as shown in FIG. 2B. Correspondingly, the trimming board 14 can include a bolt structure 140. The bolt structure 140 of the trimming board 14 can be adapted to pass through the first positioning hole 102 and the second positioning hole 122 that are respectively located on the front frame 10 and the rear housing 12 and communicated to each other, so as to prevent the frame body 100 from separating from the housing body 120. In other words, the bolt structure 140 of the trimming board 14 can achieve the function like a door latch. Besides, the trimming board 14 can further include a clamping structure 142 corresponding to the clamping hole 104 of the front frame 10. The clamping structure 142 of the trimming board 14 can be used to pass through the clamping hole 104 of the front frame 10, wherein the clamping hole 104 prevents the clamping structure 142 from separating, so that the trimming board 14 cannot be easily separated from the frame body 100.
As shown in FIG. 2C, in order to make the clamping hole 104 of the front frame 10 to effectively clamp the clamping structure 142 of the trimming board 14, the clamping structure 142 of the trimming board 14 can further include a neck portion 142a and a head portion 142b extended from the neck portion 142a in the embodiment. The head portion142b of the clamping structure 142 has a diameter larger than that of the clamping hole 104 of the front frame 10. And, the clamping hole 104 of the front frame 10 can be adapted to clamp the neck portion 142a of the clamping structure 142, so as to prevent the head portion 142b of the clamping structure 142 from separating from the clamping hole 104.
Besides, because the diameter of the head portion 142b of the clamping structure 142 is larger than that of the clamping hole 104 of the front frame 10, the head portion 142b of the clamping structure 142 and the clamping hole 104 of the front frame 10 form an interference fit, which makes the head portion 142b of the clamping structure 142 hardly to move forward during the operation of passing through the clamping hole 104 of the front frame 10. So, as shown in FIG. 2A and FIG. 2B, the front frame 10 can further include a slot 104a in the embodiment. The slot 104a of the front frame 10 can be located on the frame body 100 and communicated with the clamping hole 104. In other words, the slot 104a that is communicated with the clamping hole 104 of the front frame 10 can effectively improve the deformation capability of the clamping hole 104. During the operation that the head portion 142b of the clamping structure 142 passes through the clamping hole 104 of the front frame 10, the clamping hole 104 that is pressed through by the head portion 142b of the clamping structure 142 can be deformed toward the interior of the display module 1 with the assistance of the slot 104a. After the head portion 142b of the clamping structure 142 entirely passes through the clamping hole 104 of the front frame 10, the deformed clamping hole 104 can elastically recover to clamp the neck portion 142a of the clamping structure 142, so as to achieve the function of preventing the head portion 142b of the clamping structure 142 from separating from the clamping hole 104. Besides, if the head portion 142b of the clamping structure 142 has to entirely pass into the interior of the display module 1 through the clamping hole 104 of the front frame 10, the head portion 142b of the clamping structure 142 must pass through the rear housing 12. Therefore, the rear housing 12 can further include a first passing zone 124a in the embodiment. The passing zone 124a of the rear housing 12 can be located on the housing body 120 to be passed through by the head portion 142b of the clamping structure 142. The quantity of the slot 104a on the front frame 10 that communicates with the clamping hole 104 is not limited by FIG. 2A and FIG. 2B and can be adjusted according to the requirements of designing or restrictions of manufacturing.
Please refer to FIG. 3A and FIG. 3B. FIG. 3A is an enlarged view showing the display module 1 near the corner 100c of the frame body 100 in FIG. 1, wherein the pulling portion 160c separates from the circular groove 106 to expose the disassembly hole 108. FIG. 3B is another enlarged view showing the display module 1 near the corner 100c of the frame body 100 in FIG. 3A, wherein the trimming board 14 separates from the frame body 100 and the housing body 120.
As shown in FIG. 3A and FIG. 3B, the front frame 10 in the display module 1 of the embodiment can further include a circular groove 106 and disassembly hole 108. The circular groove 106 can be formed along a periphery of the frame body 100. The disassembly hole 108 can be located in the circular groove 106. A part of the resilient member 16 is detachably engaged in the circular groove 106 and covers the disassembly hole 108 in the circular groove 106. 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 106 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 20 and fix the glass panel 20. In other words, when the glass panel 20 is fixed to the bearing portion 100b of the frame body 100, the resilient member 16 that is engaged in the circular groove 106 of the front frame 10 is also located between the external wall 100a of the frame body 100 and the glass panel 20. Of course, the disassembly hole 108 is not necessary to be entirely located in the circular groove 106. In an embodiment, the disassembly hole 108 can be partially located in the circular groove 106 and partially located on the bearing portion 100b of the frame body 100. Accordingly, the resilient member 16 can covers the part of the disassembly hole 108 that is located in the circular groove 106, and the glass panel 20 can covers the part of the disassembly hole 108 that is located on the bearing portion 100b of the frame body 100.
As shown in FIG. 3A and FIG. 3B, the resilient member 16 in the display module 1 of the embodiment can further include a buffer portion 160a and clamped portions 160b. The buffer portion 160a of the resilient member 16 is detachably engaged in the circular groove 106 and is located between the external wall 100a of the frame body 100 and the glass panel 20, so as to be used for covering the disassembly hole 108. The clamped portions 160b and the buffer portion 160a of the resilient member 16 are connected to each other. The clamped portions 160b can be clamped between the glass panel 20 and the bearing portion 100b of the frame body 100, so as to prevent the resilient member 16 entirely separating from the circular groove 106. The quantity of the clamped portions 160b of the resilient member 16 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 disassembly hole 108 of the front frame 10 can be located in the circular groove 106 and near the corner 100c of the frame body 100. The buffer portion 160a of the resilient member 16 can further include a pulling portion 160c. In another word, the pulling portion 160c is the part of the buffer portion 160a that is near the corner 100c and between the doted lines in FIG. 3A. The pulling portion 160c of the buffer portion 160a is detachably engaged in the circular groove 106 and near the corner 100c for covering the disassembly hole 108. Besides, the pulling portion 160c of the buffer portion 160a can be interconnected between two clamped portions 160b. Thus, during the operation of pulling the pulling portion 160c located at the corner 100c of the frame body 100 to separate from the circular groove 106, the resilient member 16 will not be pulled to entirely separate the circular groove 106 because the two clamped portions 160b interconnected to the pulling portion 160c of the buffer portion 160a are clamped between the glass panel 20 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 160c of the buffer portion 160a 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 disassembly hole 108 and the clamped portions 160b of the resilient member 16 are not limited and can be adjusted according to the requirements of designing or restrictions of manufacturing.
In the embodiment, the buffer portion 160a of the resilient member 16 can be circular. The circular groove 106 can be, but not limited to, adapted to entirely accommodate the buffer portion 160a of the resilient member 16 (as shown in FIG. 1), and the buffer portion 160a of the resilient member 16 is located between the external wall 100a of the frame body 100 and the glass panel 20. For example, there can also be a plurality of resilient members disposed in the circular groove 106, 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 20 and covering the disassembly hole 108 in the circular groove 106.
Furthermore, the trimming board 14 in the display module 1 of the embodiment can further include a sloping structure 144, as shown in FIG. 2A and FIG. 2C. The sloping structure 144 of the trimming board 14 is capable of passing into the interior of the display module 1 (i.e., passing between the frame body 100 of the front frame 10 and the housing body 120 of the rear housing 12). Correspondingly, the front frame 10 can further include a second passing zone 110 corresponding to the sloping structure 144. The second passing zone 110 of the front frame 10 can be located on the frame body 100. The rear housing 12 can also include a third passing zone 124b corresponding to the sloping structure 144. The third passing zone 124b can be located on the housing body 120. Under the condition that the frame body 100 of the front frame 10 and the housing body 120 of the rear housing 12 are engaged to each other, the second passing zone 110 of the front frame 10 just faces the third passing zone 124b of the rear housing 12, and the shapes and sizes of the second passing zone 110 of the front frame 10 and the third passing zone 124b of the rear housing 12 are adapted to be passed through by the sloping structure 144 of the trimming board 14.
Please refer to FIG. 4. FIG. 4 is a section view showing the display module 1 in FIG. 1.
As shown in FIG. 4, FIG. 2A, FIG. 2B, and FIG. 2C, the sloping structure 144 of the trimming board 14 in the embodiment can further include a slope 144a. After the trimming board 14 is entirely assembled to the front frame 10 and the rear housing 12, the sloping structure 144 passing through the second passing zone 110 of the front frame 10 and the third passing zone 124b of the rear housing 12 will extend near the disassembly hole 108 of the front frame 10 at the inner side of the frame body 100, so as to make the disassembly hole 108 of the front frame 10 to face the slope 144a of the sloping structure 144.
As shown in FIG. 3A and FIG. 3B, the disassembly hole 108 located in the circular groove 106 of the front frame 10 can be communicated with the interior of the display module 1. Therefore, under the condition that the bolt structure 140 of the trimming board 14 is respectively engaged with the first positioning hole 102 of the front frame 10 and the second positioning hole 122 of the rear housing 12, firstly the pulling portion 160c of the resilient member 16 can be pulled to separate from the circular groove 106 and thus to expose the disassembly hole 108 (as shown in FIG. 3A and FIG. 3B) as long as the trimming board 14 is desired to be disassembled to separate the rear housing 12 from the front frame 10. Afterwards, because the disassembly hole 108 in the circular groove 106 of the front frame 10 is communicated with the interior of the display module 1 and just faces the slope 144a of the sloping structure 144, the slope 144a of the sloping structure 144 can be pressed through the disassembly hole 108 of the front frame 10 by any long and thin disassembly tool (e.g., a needle, a toothpick, and etc), so as to push the bolt structure 140 of the trimming board 14 away from the first positioning hole 102 of the front frame 10 and the second positioning hole 122 of the rear housing 12. So, the frame body 100 of the front frame 10 and the housing body 120 of the rear housing 12 can be unlocked to separate. It can be seen that the design of hiding/reducing screws of the display module can be achieved by replacing the screws for fastening the rear housing 12 to the front frame 10 with the trimming board 14 engaged on the front frame 10 that is capable of fastening the front frame 10 and the rear housing 12.
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/reducing screws of the display module, the approach of fastening the rear housing to the front frame by screws will be replaced by the trimming board engaged on the front frame that is capable of fastening the front frame and 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 that is fastened to the front frame and the rear housing at the same time can be pushed away through the disassembly hole, so as to separate the front frame from the rear housing.
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.
