Please refer to FIG. 2A, FIG. 2B, and FIG. 2C simultaneously. The portable electronic apparatus 200, such as a notebook, of the embodiment includes a host 210 and a display unit 220 pivotally connected to the host 210. In the embodiment, the display unit 220 mainly includes a panel module 222, a first plate 224, and a second plate 226. Wherein, the second plate 226 is suitable to be connected to the first plate 224 to hold the panel module 222 between the first plate 224 and the second plate 226. For example, the second plate 226 of the embodiment has an opening 226a, and the panel module 222 has a display area 222a exposed from the opening 226a for users to watch.
Before the second plate 226 and the first plate 224 are connected with each other to hold the panel module 222, in the embodiment, the panel module 222 is locked on the first plate 224, such as a back cover, in a tight-fitting manner. Then, the second plate 226, such as a front cover, is covered on the first plate 224 to enable the panel module 222 be provided in the display unit 220 firmly. In details, the first plate 224 of this embodiment is composed of a plate body 224a and a plurality of positioning structures 224b provided on the plate body 224a. When the panel module 222 is provided at the first plate 224, the positioning structures 224b on the first plate 224 can lock the panel module 222 on the first plate 224 effectively to make the panel module 222 tightly fit with the first plate 224.
From above, the panel module 222 of the embodiment, such as a liquid crystal panel module, is constructed of a liquid crystal panel and a back light module. The material of the first plate 224 can be plastic, and the first plate 224 is formed by the injection molding method. The positioning structures 224b are integrally formed on the plate body 224a. On the other hand, in the embodiment, to avoid the panel module 222 provided in the display unit 220 being impacted by improper external force in use, a plurality of buffer elements 230 are provided at the contact surfaces between the positioning structures 224b and panel module 222 and the contact surface between the first plate 224 and panel module 222 to absorb the shock between the first plate 224 and the panel module 222, and further to obtain a shock avoiding effect. The buffer elements 230 can be proper elastic material, such as foam layers.
The buffer elements 230 provided between the positioning structures 224b and the panel module 222 also can make the connection between the positioning structures 224b and the panel module 222 preferred. In detail, when the panel module 222 is provided at the first plate 224, the panel module 222 presses the buffer elements 230 on the positioning structures 224b, and then the buffer elements 230 exerts an elastic force on the panel module 222 relatively to the positioning structures 224b to hold the panel module 222 at the first plate 224 more effectively.
In the embodiment, the first plate 224 is plastic, but in other embodiments, the first plate 224 also can be metal. In detail, the plate body 224a can be a metal plate, and the metal positioning structures 224b can be provided at the plate body 224a by welding.
FIG. 3 is an exploded view of the display unit of another embodiment of the invention. Please refer to FIG. 3. In the embodiment, the display unit 32 includes a panel module 322, a first plate 324, a second plate 326, and a third plate 328. For example, the panel module 322 of the embodiment is a liquid crystal panel module, the first plate 324 is a positioning plate, the second plate 326 is a back cover, and the third plate 328 is a front cover. This embodiment is the same as the display unit 220 of the above embodiment. The first plate 324 of this embodiment is also composed of a plate body 324a and a plurality of positioning structures 324b provided on the plate body 324a. The panel module 322 is locked at the first plate 324 by the positioning structures 324b and tightly fits with the first plate 324.
The combination of the panel module 322 and the first plate 324 is provided at the second plate 326, such as a back cover. The third plate 328 is like a front cover to connect with the second plate 326, and the purpose is to hold the combination of the panel module 322 and the first plate 324 between the second plate 326 and the third plate 328. Certainly, in the embodiment, a plurality of buffer elements 330 such as foam layers also can be provided at the contact surfaces between the positioning structures 324b and the panel module 322 and the contact surface between the second plate 326 and the panel module 322 to avoid the panel module 322 of the display unit 320 being impacted by improper external force in use.
In the embodiment, the first plate 324, such as the positioning plate, is a plastic plate, and the positioning structures 324b of the first plate 324 are integrally formed on the plate body 324a. The second plate 326, such as the back plate, is a metal plate, and the combination of the panel module 322 and the first plate 324 can be fastened at the second plate 326 by pasting.
To sum up, in the invention, a plurality of positioning structures are provided on the first plate of the display unit to lock the panel module on the first plate and make the panel module tightly fit with the first plate, so that the panel module can be provided in the display unit firmly. Compared with the conventional technology that assembling the positioning support at two sides of the panel module by screws and then fixing the combination of the positioning support and the panel module to the back cover, the invention has following advantages:
first, since the invention utilizes the locking structure relationship to make the panel module tightly fit on the first plate, the assembly time of the display unit of the invention can be saved effectively, and then the assembly efficiency of the portable electronic apparatus is preferred;
second, since the invention utilizes the locking structure relationship to make the panel module tightly fit with the first plate, the display unit does not need extra positioning support and fasteners. That is, the portable electronic apparatus of the invention has a lower product cost.
