The electronic device 10 also includes a supporting arm 16 . The two ends of the support arm 16 are respectively pivotally connected to the first housing 12 and the second housing 14. When the second housing 14 is turned over relative to the first housing 12, it stands on the surface of the first housing 12 to provide a better When the viewing angle of the screen is high, the support arm 16 is used to support the weight of the second housing 14, assisting the hinge shaft to limit the rotation of the second housing 14 relative to the first housing 12, so as to keep the second housing 14 at a preset position. s position.

As shown in FIG. 2 , the first housing 12 has a sliding rail structure 121 , and the second housing 14 has a sliding block 141 . The sliding block 141 is movably disposed in the sliding rail structure 121 , so that the second casing 14 can perform an angular flip operation relative to the first casing 12 through the sliding combination of the sliding block 141 and the sliding rail structure 121 . In other words, the sliding of the slider 141 relative to the slide rail structure 121 is synchronized with the turning over of the second casing 14 relative to the first casing 12, so the electronic device 10 also includes a limiting element 18, which is arranged on the slide rail structure 121 and slider 141. The limiting element 18 has a compressible deformation characteristic, and is used to be installed in the gap between the slider 141 and the slide rail structure 121, and utilizes the generated frictional force to form a restraint on the slider 141, thereby slowing down the movement of the slider 141 relative to the slide rail structure 121. The fluency of movement can prevent the sliding block 141 from sliding in the sliding rail structure 121 , so as to achieve the purpose of limiting the turning angle of the second housing 14 .

Please refer to FIG. 1 to FIG. 4, FIG. 3 is an exploded schematic diagram of the partial structure of the limiting element 18 of the first embodiment of the present utility model, and FIG. 4 is a part of the limiting element 18 of the first embodiment of the present utility model Assembly diagram of the structure. The limiting element 18 of the first embodiment may include at least one compressible structure 20, and the compressible structure 20 may be made of rubber material or sponge material. As shown in FIG. 3 , the limiting element 18 has two compressible structures 20 , each of which can be a strip-like structure attached to the inner walls 123 on both sides of the slide rail structure 121 adjacent to the slider 141 . The width H1 of the slider 141 may be smaller than the width H2 of the slide rail structure 121 , and the width H1 may also be greater than the distance H3 between the two inner walls 123 of the compressible structure 20 pasted thereon. Therefore, if the slider 141 is to be installed, the user needs to apply an external force to drive the slider 141 to squeeze the two compressible structures 20 inside the slide rail structure 121 to produce compression deformation, so that the slider 141 is squeezed into the slide rail structure. Within 121.

The limiting element 18' can also include a baffle 22 and at least one elastic part 24. In the second embodiment, the limiting element 18' is provided with a baffle 22 and three elastic parts on the left and right sides of the slider 141 respectively. twenty four. The three elastic parts 24 are respectively arranged on the upper section, the middle section and the lower section of the corresponding baffle plate 22, so as to achieve the purpose of stable support without deflection. The number and arrangement positions of the elastic parts 24 are not limited to those described in this embodiment, but depend on design requirements. Two ends of each elastic portion 24 are respectively connected to the baffle 22 and the inner wall 123 of the slide rail structure 121 . The user can apply pressure on the slider 141 to push the baffle 22 to drive the elastic portion 24 to produce elastic deformation, so as to push the slider 141 into the slide rail structure 121 in a pressing manner.

The surface of the baffle 22 used to contact the slider 141 can optionally be distributed with multiple groups of rough surface structures 221 . The function of the rough surface structure 221 is to increase the coefficient of friction of the sliding block 141 sliding relative to the baffle plate 22 . When the slider 141 moves along the slide rail structure 121 as the second housing 14 turns over relative to the first housing 12, the plurality of elastic parts 24 utilize their elastic restoring force to drive the two baffle plates 22 from the two sides of the slider 141. Apply sideways pressure. With the roughness design of the surface of the baffle plate 22 (the density and size of the rough surface structure 221) and the clamping force driven by the elastic part 24, the movement of the slider 141 in the slide rail structure 121 can be effectively restricted, thereby achieving restriction The purpose of the second shell 14 turning over relative to the first shell 12 . The multiple sets of rough surface structures 221 may be multiple sets of granular structures, but it 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 protrusion, and the number of engaging portions 26 corresponds to the number of the elastic portions 24 . Each elastic portion 24 can be sleeved on the corresponding engaging portion 26 to be connected to the baffle 22 . The engaging design of the engaging portion 26 can effectively prevent the elastic portion 24 from being separated from the baffle 22 due to external impact. In addition, the sliding rail structure 121 can also have a plurality of limiting grooves 125 , wherein the number of limiting grooves 125 corresponds to the number of the elastic parts 24 . Each elastic portion 24 can be disposed in the corresponding limiting groove 125 to limit the range of movement of the elastic portion 24 and prevent it from detaching from the slide rail structure 121 . The slide rail structure 121 can also have two stopper walls 127 , which are located at the upper and lower ends of the baffle plate 22 . When the baffle 22 is driven by the elastic restoring force of the elastic portion 24 to move, its upper and lower ends contact the stop wall 127 and slide along the stop wall 127 to avoid irregular shaking of the baffle 22 during the moving process. Wherein, the moving direction of the baffle plate 22 may be parallel to the wall extension direction of the stop wall 127 .

In addition, the limiting element 18' can also include a plurality of positioning pins 28, and the baffle 22 can include a plurality of guide grooves 223. The number of positioning pins 28 corresponds to the number of guide grooves 223 . The positioning pin 28 can pass through the corresponding guide groove 223 so that the baffle 22 can be limited in the slide rail structure 121 . Since the baffle 22 can be driven by the elastic restoring force of the elastic portion 24 to slide, the size of the inner diameter L1 of the guide groove 223 (that is, the dimension in the longitudinal direction) can be greater than the size of the outer diameter L2 of the positioning pin 28, and the baffle 22 A small sliding can be produced under the restriction of the positioning pin 28 to cooperate with the elastic restoring force of the elastic part 24 to tightly clamp the slider 141 to achieve the purpose of restricting the turning of the second housing 14 . As shown in Figure 6, the two sets of baffles 22 are driven by the elastic parts 24 on both sides to generate displacement, and by the combination of the positioning pin 28 and the guide groove 223, the sliding block 141 is tightly pressed and clamped from both sides. Block 141, and then generate friction to achieve the effect of limiting displacement. It is worth mentioning that the baffles 22 are made of materials that cannot be elastically deformed, so that the two baffles 22 can still maintain their structures parallel to each other under the extrusion of the elastic part 24 and the slider 141, and along the The stopper wall 127 slides to ensure that the left and right sides of the slider 141 receive uniform and balanced clamping force respectively.

To sum up, the electronic device of the present utility model uses the limiting element to clamp and compress the slider, so as to slow down the smoothness of the slider relative to the slide rail structure by using friction force. In this way, when the second housing is relatively When the casing is turned over, the limiting element can limit the turning angle of the second casing through the displacement of the stopper slider, so as to fix the screen end (the second casing) at a better viewing angle. The limiting element of the present invention discloses two embodiments. In the first embodiment, the structural deformation of the compressible structure is used to softly cover the slider, thereby generating friction to limit the displacement of the slider. In the second embodiment, a hard baffle is used to squeeze and clamp the slide block, and the power to drive the baffle comes from the elastic part arranged on its side. The baffle plate of the second embodiment can also use the guide of the stop wall and the combination of the positioning pin and the guide groove to stabilize the moving direction of the baffle plate, thereby ensuring that the baffle plate can apply positive force to both sides of the slider , in order to generate friction to achieve the effect of limiting the displacement of the slider. The implementation of the limiting element of the present invention is not limited to the foregoing embodiments, but depends on design requirements.
