Creation Instructions (1) [Technical Field to which the New Type belongs] This creation relates to external modules, especially a connection structure used to combine external modules with a projector. [Previous technology] Projectors are commonly used in presentations or home audio-visual. With the increase of users' functional requirements, the functions of the projector itself are no longer sufficient. Therefore, external modules have been developed that can provide additional functions, such as The external wireless transmission module, the external optical storage module, the external input control module, etc. are connected to the projector through the external module, and the function of the projection device can be dynamically increased according to the needs of the user. Please refer to FIG. 1, a plurality of openings 1 1 1 are provided at the upper end of the back of the conventional projector 1 1, a connecting base 1 1 2 is provided at the lower end, and a hook 1 2 1 is convexly provided at the upper end of the external module 12 , The lower end is provided with a connector 1 2 2, and the hook 1 2 1 is fastened to the opening 1 1 1 and the connector 1 2 2 is combined with the connector 1 2 1 to assemble the external module 1 2 to the projector 1 1 . Of course, the rigid structure of the hook 1 2 1 and the connector 1 2 2 is used to fix the external module 1 2. When the processing margin of each component (such as: hook 1 2 1, opening 1 1 1, etc.) is too large , Will make the external module 12 easily loosen after assembly, resulting in the external module 12 and the projector 11 cannot be tightly connected, which affects the transmission efficiency and effect between the external module 12 and the projector 11. [New content 1] One of the purposes of this creation is to provide a connection structure for plug-in modules. The use of elastic elements is provided to achieve processing and assembly margins.

M254869 4. Creation Instructions (2) Another purpose of this creation is to provide a connection structure for external modules.

In order to achieve the above purpose, the connection structure of the plug-in module is used to connect the external module to the projector. The connection structure includes a guide element, a latch element, an elastic element, and an opening; the guide element is fixed on the On the external module, a latching element is movably sleeved on the guide element. The latching element has a buckling part protruding from the external module. One end of the elastic element is fixed to the external module and the other end resists the latch. Locking element ', the opening is set on the back of the projector; when the external module is combined with the projector, the latching element is acted by the elastic element to absorb the assembly tolerances so that the external module can be closely fitted to the projector. [Embodiment] Regarding the technical means and other effects used in this creation to achieve the above-mentioned purpose, a preferred embodiment is described below with reference to the drawings: Please refer to FIG. 2 and FIG. The creative connection structure is used to connect an external module 2 2 to a projector 2 3 on the back 2 3 1. The external module 2 2 is composed of a box body 2 2 1 and a cover plate 2 2 2 on the cover plate 222. It is provided with a through hole 2221 and an inner surface 2222, a projector 2 3, and a back 2 3 1 with a first opening 2 3 2, a second opening 2 3 3 and a connector 2 3 4, and an external module 2 2 series A connecting base 2 2 3 is connected to the connector 2 3 4; the connecting structure includes a guide element 2 1 1, a latching element 2 1 2, a first elastic element 2 1 3 and

M254869 4. Creation instructions (3) A pressing structure 2 1 4; the guide element 2 1 1 is vertically fixed on the cover 2 2 2 inside surface 2 2 2 2, and the latch element 2 1 2 is sleeved on the guide element 2 1 1 and corresponding to the first opening 2 3 2, it has a door-shaped body 2 1 2 1 and a first latching portion 2 1 2 2 connected to one end of the body 2 1 2 1. 2 1 2 1 is perpendicular to the inner surface 2222 of the cover 2 2. A through hole 2123 is provided in the center and penetrates the guide element 2 1 1. The through hole 2 1 2 3 is larger than the guide element 2 1 1 Shaft diameter so that the body 2 1 2 1 can be guided by the guide element 2 1 1 to

It moves linearly with respect to the external module 2 2 and the first latching portion 2 1 2 2 passes through the perforation 2 2 2 1 of the cover 2 2 2 and protrudes beyond the cover 2 2 2. The first latching portion 2 1 2 2 is used for engaging in the first opening 2 3 2; and the first elastic element 2 1 3 is provided between the latch element 2 1 2 and the cover plate 222, and one end thereof is fixed to the inner surface of the cover plate 222 2222, the other end resists the inner surface of the latch element 2 1 2 body 2 1 2 1 and the elastic deformation direction of the first elastic element 2 1 3 is the vertical cover 2 2 2;

The pressing structure 2 1 4 is arranged on both sides of the external module 2 2. Each pressing structure 214 includes a stopper 2141, a pressing portion 2142 and a second elastic element 2 1 4 3, and the stopper 2 1 4 1 It is formed by suspending a fixing base 2141 1 on the inner surface 2222 of the cover plate 222. The pressing portion 2 1 4 2 includes a button-shaped body 2 1 4 2 1 and a second "second snap portion 2 1" provided on its end. 4 2 2, the second buckling portion 2 1 4 2 2: is protruding vertically from the cover 2 2 2, and the second buckling portion 2 1 4 2 2 is used to be engaged with the second opening 2 2 3 Inside, the box body 2 2 1 is provided with an opening 2 2 1 1 on the side to make the body 2 1 4 2 1 convex

Page 10 M254869 IV. Creation instructions (4) Out of the box 2 2 1 side, one end of the second elastic element 2 1 4 3 is connected to the pressing portion 2 1 4 2 and the other end is restricted by the stopper 2 1 4 1, the elastic deformation direction is parallel to the pressing direction of the pressing portion 2 1 4 2. Refer to FIG. 2 and FIG. 3 again, and refer to the operating states of the latch element shown in FIGS. 4A and 4B. In the figure, the box body 2 2 1 is removed and is a top view. When the portion 2 1 42 is pressed, the second buckling portion 2 1 4 2 2 is contracted in a horizontal direction, the second elastic element 2 1 4 3 is compressed, and then the first buckling portion 2 1 2 2 and the second card are compressed. The buckling portions 2 1 4 2 2 are respectively aligned with the first opening 2 2 2 and the second opening 2 3 3 of the projector, and then release the pressing portion 2 1 4 2 so that the first buckling portion 2122 is locked. Fit in the first opening 232, and the second buckling portion 2 1 4 2 2 fits in the second opening 2 3 3 to tightly connect the external module 2 2 and the projector 2 3 at the same time The connector 2 3 4 is connected to the connection seat 2 2 3. Since the first buckling portion 2 1 2 2-the end is hooked on the fixed first opening 2 3 2 and is affected by the elastic element 2 1 3, the external module 2 2 can be forced to fit on the projector 2 3 and The external module 2 2 is restricted from moving forward and backward, and the second latching portion 2 1 4 2 2 —the end is hooked on the fixed second opening 2 3 3 and is forced by the elastic element 2 1 4 3 to the second latching portion 2 1 4 2 2 presses the second opening 2 3 of the projector 2 3, the inner wall, and can restrict the left and right displacement of the external module 2 2. Therefore, when each component (such as: the snap portion 2 1 2 2, the opening 2 3 2 etc.) When the processing margin is too large, the assembly margin will be absorbed by the elastic element 2 1 3, 2 1 4 3, so it can solve the assembly of the external module 2 2

M254869 Fourth, the problem of easy loosening after the creation description (5), so that the external module 2 2 and the projector 2 3 have the best transmission effect, and the use of elastic components 2 1 3, 2 1 4 3 settings to provide Compared with the conventional rigid connection structure, the elastic connection structure can improve the convenience of assembly. The above is only for the convenience of explaining the preferred embodiments of this creation, and the scope of this creation is not limited to these preferred embodiments. Any changes made in accordance with this creation will not depart from the spirit of this creation. It is within the scope of this creation application patent.
