Among them, FIG. 3A and FIG. 3B are schematic diagrams when the anti-skid mechanism is not in operation, and FIG. 4A and FIG. 4B are schematic diagrams when the anti-skid mechanism is in operation. Here, "the anti-skid mechanism is not in operation" means that the anti-skid mechanism is not in operation and no bumps are formed; and "the anti-skid mechanism is in operation" means that the anti-skid mechanism is in operation and a plurality of bumps are formed.

Please refer to FIG. 1A and FIG. 1B , the electronic device 1 includes a housing 11 and at least one anti-skid mechanism 2. The housing 11 has a display surface 111 and a back surface 112 opposite to the display surface 111. The display surface 111 is used to display images, and the at least one anti-skid mechanism 2 is disposed on the back surface 112 of the housing 11. Here, the back surface 112 of the housing 11 has a groove 1121 corresponding to the shape of the anti-skid mechanism 2, and the anti-skid mechanism 2 can be disposed in the groove 1121. When the anti-skid mechanism 2 is not activated, the back surface 112 of the housing 11 and the surface of one side of the anti-skid mechanism 2 are substantially coplanar (FIG. 1A), so that the original thin and light appearance of the electronic device 1 is not affected, and the integrity of the design can be maintained. In addition, when the anti-skid mechanism 2 is in operation, a plurality of protrusions 221 ( FIG. 1B ) are formed, so that the user is not likely to slip and cause damage when using the electronic device 1. In this embodiment, there are two anti-skid mechanisms 2, which are disposed on opposite sides of the back surface 112 of the housing 11.

2A to 4B , the anti-slip mechanism 2 may include a base 21, an elastic membrane 22, a lifting unit 23 and a driving unit 24. The driving unit 24, the lifting unit 23, the base 21 and the elastic membrane 22 are stacked in sequence from bottom to top to constitute the anti-slip mechanism 2 of this embodiment.

The base 21 includes a substrate 211 and a plurality of through holes 212. Here, the substrate 211 has a first surface S1 and a second surface S2 opposite to the first surface S1. The through holes 212 are arranged in an array, for example, and each through hole 212 penetrates the first surface S1 and the second surface S2 of the substrate 211 respectively. The through holes 212 of this embodiment are arranged in a two-dimensional array as an example. Of course, the arrangement of the through holes 212 is not limited to this. The substrate 211 can be made of a high-hardness material, such as but not limited to plastic steel or other suitable materials. In some embodiments, the base 21 and the housing 11 of the electronic device 1 can be independent components; in some embodiments, the base 21 and the housing 11 of the electronic device 1 can be integrally formed to form a single component. This embodiment takes the base 21 and the housing 11 of the electronic device 1 as an example of independent components.

The elastic film 22 is disposed on the first surface S1 of the substrate 211 and covers the through holes 212. Here, the elastic film 22 is attached to the first surface S1 of the substrate 211 and covers all the through holes 212. When the anti-slip mechanism 2 is not activated, such as shown in Figures 1A, 2A, 3A and 3B, the elastic film 22 is a flat surface; when the anti-slip mechanism 2 is activated, such as shown in Figures 1B, 4A and 4B, the elastic film 22 can be deformed to form a plurality of protrusions 221, thereby increasing the friction force. The elastic film 22 is made of a soft material with elasticity, such as but not limited to silicone or other suitable materials.

The lifting unit 23 is movably disposed on the second surface S2 of the substrate 211 (i.e., the side opposite to the elastic film 22). The lifting unit 23 of this embodiment can be moved in a direction perpendicular to the second surface S2 (e.g., the third direction D3 of FIG. 4A and the opposite direction thereof) to rise or fall, wherein the lifting unit 23 can approach the substrate 211 of the base 21 when it rises, so that the elastic film 22 can form a convex point 221; and the lifting unit 23 can be away from the substrate 211 of the base 21 when it falls, so that the elastic film 22 becomes a flat surface. The lifting unit 23 can include a body 231 and a plurality of protruding posts 232 protruding from the body 231 toward the substrate 211, and the protruding posts 232 are arranged corresponding to the through holes 212. Here, each protrusion 232 is perpendicular to the surface of the body 231 and is formed integrally with the body 231, and the end of each protrusion 232 is substantially coplanar, and the substrate 211 is located between the body 231 and the elastic film 22, and each protrusion 232 can be respectively penetrated through each through hole 212. When the lifting unit 23 is not lifted and is away from the substrate 211 of the base 21 (that is, when the body 231 is located at the second position), there is a distance d (Figure 3B) between the body 231 and the second surface S2 of the substrate 211, and the end of each protrusion 232 is located in each through hole 212, and each protrusion 232 can contact or not contact the elastic film 22. The lifting unit 23 can be made of a high-hardness material, such as but not limited to plastic steel or other suitable materials.

The driving unit 24 is disposed on a side of the lifting unit 23 away from the base 21. The driving unit 24 is connected to the lifting unit 23 and is suitable for driving the body 231 of the lifting unit 23 to be located at a first position close to the substrate 211 (as shown in FIG. 4A and FIG. 4B) or a second position away from the substrate 211 (as shown in FIG. 3A and FIG. 3B). When the body 231 of the lifting unit 23 is located at the first position, the protruding columns 232 can protrude from the first surface S1 and push the elastic film 22 to deform to form a plurality of protrusions 221. When the body 231 of the lifting unit 23 is located at the second position (i.e., each component is located at the initial position), the elastic film 22 can return to its original state and present a plane. Specifically, as shown in FIG. 4A and FIG. 4B , when the driving unit 24 drives the body 231 of the lifting unit 23 to move toward the third direction D3 close to the substrate 211 and reaches the first position, the protruding columns 232 of the lifting unit 23 can push the elastic film 22 to deform to form a plurality of protrusions 221. In addition, as shown in FIG. 3A and FIG. 3B , when the driving unit 24 drives the body 231 of the lifting unit 23 to move away from the substrate 211 (the opposite direction of the third direction D3) and reaches the second position, the elastic film 22 can restore its original state due to its own elasticity, the protrusions 221 disappear, and the elastic film 22 presents a flat surface and is coplanar with the back surface 112 of the housing 11.

The driving unit 24 of this embodiment includes a driving member 241 and a sliding member 242 connected to each other. The sliding member 242 is disposed on a side of the lifting unit 23 opposite to the base 21. The driving member 241 includes a transmission part 243, and when the driving member 241 moves, the transmission part 243 can drive the sliding member 242 to move along a first direction D1 parallel to the second surface S2 of the substrate 211 or a second direction D2 opposite to the first direction D1 (as shown in Figures 3A and 4A), so that the sliding member can drive the body 231 of the lifting unit 23 to move to the first position or the second position. The driving member 241 of this embodiment is, for example, a stepping motor; the transmission part 243 is, for example, a gear; and the sliding member 242 can be made of a high-hardness material, such as but not limited to plastic steel or other suitable materials.

The sliding member 242 of this embodiment includes a linking portion 2421 protruding in a direction away from the lifting unit 23. The linking portion 2421 has a through hole h, and the transmission portion 243 can pass through the through hole h and be disposed in the through hole h. In addition, the linking portion 2421 can form a linking structure 2422, and the linking structure 2422 is arranged in cooperation with the transmission portion 243. Here, the linking structure 2422 is, for example, a gear, and is engaged with the transmission portion 243 (gear). Therefore, when the transmission part 243 (gear) of the driving member 241 rotates, the rotation of the transmission part 243 can be converted into linear motion through the engagement of the transmission part 243 (gear) and the linkage structure 2422 (tooth bar), so that the driving member 241 can drive the sliding member 242 to move in the first direction D1 or the second direction D2 through the transmission part 243 and the linkage part 2421. When the sliding member 242 moves in the first direction D1, the lifting unit 23 can be lifted in the third direction D3 to reach the first position and approach the base plate 211 of the base 21, and the protruding columns 232 can push the elastic film 22 to deform to form a plurality of protrusions 221 (FIG. 4A, FIG. 4B). When the sliding member 242 moves in the second direction D2, the sliding member 242 no longer pushes against the lifting unit 23, and the lifting unit 23 can be lowered in the opposite direction of the third direction D3 through the restoring elastic force of the elastic membrane 22 or an elastic mechanism (not shown) additionally provided and connected to the lifting unit 23, thereby returning to the second position of the substrate 211 away from the base 21, and the elastic membrane 22 can return to its original state and present a plane (Figures 3A and 3B). In practice, in order to fix the driving member 241 and its transmission part 243, for example, two protruding fixing parts 2111 (Figure 2B) can be set on the second surface S2 of the substrate 211. The two fixing parts 2111 can pass through the main body 231 and the sliding member 242 (the main body 231 and the sliding member 242 must have corresponding holes) to fix (clamp) the driving member 241 and its transmission part 243.

In addition, the sliding member 242 may further include at least one protrusion 2423 protruding toward the main body 231 of the lifting unit 23, and the main body 231 also includes at least one recess 2311 arranged corresponding to the at least one protrusion 2423. When the driving member 241 drives the sliding member 242 to move along the second direction D2, the main body 231 is driven away from the substrate 211 to restore the elastic film 22 to its original state and present a plane (as shown in Figure 3A). At the same time, the protrusion 2423 moves to the recess 2311 to return the main body 231 to the second position. Each of the two opposite sides of the sliding member 242 of the present embodiment has two spaced-apart protrusions 2423, and each of the two opposite sides of the main body 231 has two recesses 2311 corresponding to the two protrusions 2423, so that when the anti-slip mechanism 2 is not actuated (or returns to its initial position), each protrusion 2423 is located in the corresponding recess 2311, and when the protrusion 2423 is located in the recess 2311, the elastic membrane 22 can present a flat surface.

In order to convert the lateral movement of the sliding member 242 (toward the first direction D1 or the second direction D2) into the longitudinal movement of the lifting unit 23 (toward the third direction D3 or the opposite direction), each protrusion 2423 of the present embodiment has an inclined surface 2424, and the body 231 further includes a plurality of extensions 2312 adjacent to the recess 2311, and each extension 2312 is disposed corresponding to each protrusion 2423. Here, each of the two opposite sides of the body 231 has two extensions 2312 corresponding to the two protrusions 2423. Therefore, when the driving member 241 drives the sliding member 242 to continuously move in the first direction D1 through the transmission part 243 and the linkage part 2421, the inclined surface 2424 of the protrusion 2423 can move relative to the recessed part 2311, so that the inclined surface 2424 can lift the extension part 2312 to push the main body 231 to move in the third direction D3. Finally, the protrusion 2423 can push against the lower edge 2313 of the extension part 2312, so that the main body 231 moves to the first position (Figure 4A), so that the protrusion 232 of the lifting unit 23 can push the elastic film 22 to deform and form the protrusion 221, thereby increasing the friction of the electronic device 1 so that the electronic device 1 is not easy to slip when in use. On the contrary, when the driving member 241 of the driving unit 24 drives the sliding member 242 to move in the second direction D2 through the transmission part 243 and the linkage part 2421, so that the lifting unit 23 moves away from the substrate 211 (the opposite direction of the third direction D3) and away from the base 21, as shown in Figure 3A, each protrusion 2423 can be located in the corresponding recess 2311, and the elastic membrane 22 can present a flat surface and return to its original state.

In practice, the driving member 241 can drive the sliding member 242 to move on one side (such as the above-mentioned embodiment of the present application), or can drive the sliding member 242 to move on both sides synchronously, without limitation. In addition, the power source of the anti-skid mechanism 2 can be the battery of the anti-skid mechanism 2 itself, or can come from the battery of the electronic device 1, also without limitation. In some embodiments, the anti-skid mechanism 2 can receive a control command to control the lifting unit 23 to lift and lower to be located at the first position or the second position (close to or away from the substrate 211 of the base 21). The source of the control command can be an application (such as an app) installed in the electronic device 1, or a physical or virtual button set in the electronic device 1 or the anti-skid mechanism 2, and the present invention is not limited thereto.

In summary, in the anti-slip mechanism and the electronic device having the anti-slip mechanism of the present invention, the elastic film is disposed on the first surface of the substrate and covers the through-holes of the substrate, the lifting unit is movably disposed on the side opposite to the elastic film, and each protrusion of the lifting unit is respectively penetrated through each through-hole, and the driving unit is connected to the lifting unit and is suitable for driving the main body of the lifting unit to be located at a first position (close to the substrate) or a second position (far away from the substrate). substrate); wherein, when the body is located at the first position, the protruding posts penetrate the first surface and push the elastic film to deform to form a plurality of protrusions; when the body is located at the second position, the elastic film presents a planar structural design, so that the electronic device of the present invention can add a lifting anti-slip mechanism to form a plurality of protrusions without affecting the thin and light appearance and the overall design, so that the electronic device will not slide and cause damage when being used.
