[Embodiment] Please refer to FIG. 1 and FIG. 2, and FIG. 1 and FIG. 2 are respectively schematic views of the electronic device 10 according to the first embodiment of the present invention at different viewing angles. The electronic φ device 10 can be a notebook computer including a first housing 12 and a second housing 14. The first housing 12 is a host end, and is internally provided with electronic components such as a keyboard, a motherboard, a hard disk drive, and a microprocessor. The second housing 14 is a screen end and is provided with a display panel. The second housing 14 is reversibly disposed on the first housing 12 through a hinge shaft, so that the electronic device 10 is a foldable open type notebook computer. The electronic device 10 further includes a support arm 16. The two ends of the support arm 16 are respectively connected to the first housing 12 and the second housing 14. When the second housing I 14 is turned over with respect to the first housing 12, it is provided on the surface of the first housing 12 to provide In a preferred viewing angle of the screen, the support arm 16 is used to support the weight of the second housing 14 to assist the hinge shaft to restrict the rotation of the second housing 14 relative to the first housing 12 to move the second housing 14 Keep at the preset position. As shown in Fig. 2, the first housing 12 has a sliding structure 121, and the second housing 14 has a slider 141. The slider 141 is movably disposed in the slide-rail structure 121 such that the second housing 14 can be angularly inverted relative to the first housing 12 by the sliding combination of the slider 141 and the slide rail structure 121. operating. In other words, the slip of the slider 141 relative to the slide rail structure 121 is synchronous with the flipping of the second 7 housing 14 relative to the first housing 12, so the electronic device further includes a limiting component 18 disposed on the sliding structure. Between 21 and slider Mi. The limiting element 18 has a compressible deformation property for the gap between the slider (4) and the sliding structure (2), and the generation of the friction force generates a restraint on the slider mi, thereby slowing down the relative sliding rail structure of the slider 141. a] the fluency of the movement, the barrier slider 141 is moved in the row of the rail structure 121 (10) to achieve the purpose of limiting the flip angle of the second housing 14. See the first! 4 to 3, FIG. 3 is a schematic exploded view of a part of the structure of the limit 7L member 18 of the first embodiment of the present invention, and FIG. 4 is a partial structure of the position limiting member 18 of the first embodiment of the present invention. Group diagram. The limiting member 18 of the first embodiment may comprise at least one compressible structural body 2, and the compressible structural body 20 may be composed of a rubber material f or a sponge material. As shown in FIG. 3, the limiting member 18 has two compressible structural bodies 2, which may each be a long sheet-like structure, respectively attached to the inner wall of the sliding rail structure 121 adjacent to both sides of the slider 141. 123. The width hi of one of the sliders 141 may be substantially smaller than the width H2 of one of the rail structures 121, and the width m$ may be substantially greater than the distance between the two inner walls 123 of the bonded compression structure 20. Therefore, if the slider 141 is to be mounted, the user needs to apply an external force to drive the slider 141 to press the two compressible structures 2 inside the sliding structure 121 to generate a compression deformation, so that the slider 141 can be squeezed into the slider 141. Inside the slide rail structure 121. In general, a surface of the compressible structure 20 for contacting the slider 141 can be specially treated to increase the surface confidentiality thereof, thereby increasing the friction coefficient thereof, so that the slider 14! can have the slide rail structure 121. The stepless limit function M443792 can be used to achieve the requirement of arbitrarily adjusting the viewing angle of the second housing 14. In addition, the compressible structure 20 is adhered to the inner wall 123 of the slide rail structure 121. When the slider 141 is inserted into the slide rail structure 121, a portion of the structure of the compressible structure 20 is pressed by the slider 141. The depression is deformed, so that the side of the slider 141 is covered by the compressible structure 20, as shown in FIG. 4, so that the friction between the slider 141 and the compressible structure 20 can be further increased to prevent the slider. 141 moves relative to the slide rail structure 121, that is, prevents the second housing 14 from flipping relative to the first shell φ body. Please refer to FIG. 5 and FIG. 6 , FIG. 5 is a schematic exploded view of a part of the structure of the limiting component 18 ′ according to the second embodiment of the present invention, and FIG. 6 is a limiting component of the second embodiment of the present invention. A group diagram of the structure of the 18'. The limiting member 18' may further include a baffle 22 and at least one elastic portion 24. In the second embodiment, the limiting member 18' is provided with a baffle 22 and three elastic portions on the left and right sides of the slider 141. twenty four. The three elastic portions 24 are respectively disposed at the upper, middle and lower portions of the opposite baffle 22 to achieve stable support without deflection. The number and position of the elastic portions 24 may not be limited to those described in the embodiment, depending on the design requirements. Both ends of each elastic portion 24 are connected to the baffle 22 and the inner wall 123 of the slide rail structure 121, respectively. The user can press the slider 141 to push the shutter 22 to drive the elastic portion 24 to elastically deform to insert the slider 141 into the sliding structure 121 in an extruded manner. The baffle 22 is adapted to contact the surface of one of the sliders 141 to selectively distribute the complex array rough surface structure 221. The function of the rough surface structure 221 is to increase the coefficient of friction of the slider 141 relative to the baffle 22 slip. When the slider 141 moves along the slide rail structure 121 along with the second 9 J1443792 housing 14 flipped relative to the first housing 12, the plurality of elastic portions 24 drive the two jaws 22 from the slider 141 by its elastic restoring force. Apply pressure on both sides. By the roughness design of the surface of the baffle 22 (the density and size of the rough surface structure 221) and the clamping force driven by the elastic portion 24, the movement of the slider M1 on the slide rail structure 121 can be effectively limited, thereby achieving the limitation. The second housing 14 is inverted relative to the first housing 12. The rough surface structure 221 may be composed of a complex array of granular structures, but is not limited thereto. As shown in Fig. 5, the baffle 22 can have a plurality of engaging portions 26, and the engaging portion 26 can be a stud, and the number of the engaging portions 26 corresponds to the number of the elastic portions 24. The engagement design of each of the elastic portions 24 that can be sleeved on the corresponding engaging portion 26 to be coupled to the engaging portion 26 of the baffle 22 can effectively prevent the elastic portion from coming off the baffle 22 due to an external force. Furthermore, the sliding structure 121 may further have a plurality of limiting slots 125' wherein the number of limiting slots 125 corresponds to the number of elastic portions. Each elastic portion 24 can be disposed in the corresponding limiting slot 125 to limit the movable range of the elastic portion 24 to prevent it from coming off the sliding rail structure 12, and the sliding structure can also have two stopping walls 127. The upper and lower ends of the baffle 22. When the support plate 22 is driven by the elastic restoring force of the elastic portion 24, the upper and lower ends are in contact with the stop wall 127 and slide along the stop wall 127 to prevent the baffle 22 from generating irregular sway during the movement. . Wherein, the direction of movement of one of the baffles 22 can be substantially parallel to the structure of one of the stops 127. In addition, the limiting component 18 can further include a plurality of positioning pins 28, and the supporting plate 22 can include a plurality of guiding slots 223. The number of locating pins 28 corresponds to the number of guide slots 223. The positioning pin 28 can be inserted into the corresponding guiding groove, and the M443792 22 T is limited to the sliding rail structure 121. Since the rafting plate 22 can be driven by the elastic restoring force of 4 24, the inner diameter L1 of the guiding groove milk can be It is substantially larger than the outer diameter dimension 3 of the positioning pin 28. Further, a small amount of sliding can be generated under the restriction of the positioning pin 28, and the elastic restoring force of the elastic portion 24 can be used to tightly hold the slider 141 to restrict the first housing 14 from being reversed. As shown in FIG. 6, the two multicast plates 22 are driven by the side elastic portion 24 to generate displacement, and are tightly pressed from both sides of the slider 141 by the combination of the positioning pin and the guide groove such as the limit of the guide groove. The slider is lost, and friction is generated to achieve the effect of limiting displacement. It is worth mentioning that the baffle 22 is composed of a material that is not elastically deformable, so that the two slabs 22 can maintain the structure parallel to each other under the squeezing of the elastic portion 24 and the slider 141. The occlusion 127 is slid to ensure that the left and right sides of the slider (4) are respectively subjected to a uniformly balanced clamping force. In summary, the electronic device of the present invention uses a limiting component to clamp and press the slider to reduce the smoothness of the slider relative to the sliding structure by friction, so that when the second housing When the first housing is turned over, the limiting member can limit the flip angle ' of the second housing by the displacement of the stop slider to fix the screen end (second housing) at a better viewing angle. The limit element of this creation discloses an embodiment of the rain. The first embodiment uses the structural deformation of the compressible structure to soften the slider, thereby generating a frictional force to limit the displacement of the slider. In the second embodiment, the slider is squeezed by a rigid baffle, and the force of driving the jaw is derived from the elastic portion provided at the side thereof. The broadcast board of the second embodiment can also utilize the guidance of the soil support and the combination of the positioning pin and the guide groove to stabilize the movement direction of the board JM43792, thereby ensuring that the baffle can apply a positive force to the slider two. On the side, the effect of limiting the displacement of the slider is achieved by generating friction. The implementation of the limit component of the present invention may not be limited to that described in the foregoing embodiment, depending on the design requirements. Compared to the prior art, the present invention utilizes a stop element to limit the movement of the slider relative to the sliding structure, thereby simultaneously stopping the flipping movement of the second housing relative to the first housing. The creation has the advantages of simple structure and easy operation, and the limiting element frictionally stops the slider, and can provide the user to arbitrarily adjust the viewing angle of the second housing relative to the first housing in a stepless rotation manner. The above descriptions are only preferred embodiments of the present invention, and all changes and modifications made to the scope of the patent application are subject to the scope of this creation.
