[0036] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0037] The technical solutions of the present invention will be described clearly and completely below in association with the specific embodiments and the accompanying drawings. It should be noted that when an element is referenced as being "mounted or attached to" another element, this means that the element may be directly on the other element or that an intermediate element may also be present. When an element is referenced as being "connected" to another element, this means that the element may be directly connected to the other element or that intermediate elements may also be present. In the illustrated embodiment, the directions indicated as up, down, left, right, forward and backward, etc., are relative and are used to explain that the structures and movements of the various elements are relative in this case. These representations are appropriate when the elements are in the positions indicated in the figures. However, if the description of the positions of the elements changes, it is believed that these representations will change accordingly.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art of the present invention. The terminology used herein is used only to describe particular embodiments and is not intended to limit the present invention. As used herein, the term "and / or" includes all combinations of one or more of the listed elements together.

[0039] The "vacuum surface adhesion state" referred to herein document is the working principle of a suction cup. When the suction cup is attached to a surface of an object and when the surrounding pressure (atmospheric pressure) is higher than the pressure between the suction cup and the surface, a lower pressure is generated between the suction cup and the surface, and the lower the pressure, the higher the degree of vacuum and the stronger the gripping force of the suction cup, thus creating a state of vacuum surface adhesion between the suction cup and the surface.

[0040] [Fig.l] shows a three-dimensional view of the present invention. The multi-surface adhesion fixing device 10 of the present invention comprises a shell assembly 20, a magnetic surface adhesion assembly 30 and a suction cup assembly 40. The suction cup assembly 40 comprises a suction cup body 41 and a release member 42. The suction cup body 41 is installed exposedly on the shell assembly 20, and the suction cup body 41 is used for adhering to a flat contact surface so as to form a vacuum surface adhesion state. The magnetic surface adhesion assembly 30 is disposed in the shell assembly 20 and adjacent to the suction cup body 4L. The magnetic surface adhesion assembly 30 is magnetically attracted to a metal object having a contact surface.The release member 42 is installed on the shell assembly 20 and is located opposite the suction cup body 4L. The release member 42 contacts the suction cup body 41 after being actuated, and . the vacuum surface adhesion state between the suction cup body 41 and the contact surface is released during the contact process. The metal object may be the surface of another device, such as a mobile phone, a tablet computer, etc., but is not limited to it. The fixing device 10 of the present invention has dual effects of surface adhesion and fixing, such as magnetic attraction and vacuum suction, and since the shell assembly 20 has a floating structure, the magnetic attraction and vacuum suction can achieve the most suitable surface adhesion effect.

[0041] When the user uses the fixing device 10 of the present invention, the fixing device 10 is first placed on the contact surface of the metal object, and the magnetic surface adhesion assembly 30 is magnetically fixed to the contact surface to first achieve the magnetic attraction effect. Then, an external force is applied to the fixing device 10 to lower the position of the suction cup body 41 continuously. During the lowering of the suction cup body 41, the air between the suction cup body 41 and the contact surface is expelled, so that the suction cup body 41 is in contact with the contact surface, and a negative pressure vacuum surface adhesion state is generated between the suction cup body 41 and the surface, thereby achieving the vacuum surface adhesion effect in a second step.Therefore, in order to achieve such an actuation mode, the shell assembly 20 of the present invention adopts a structure of at least two pieces, and two pieces are respectively combined with the magnetic surface adhesion assembly 30 and the suction cup assembly 40 to meet the requirements of different stages during actuation.

[0042] As shown in Figures 2 and 4, the shell assembly 20 includes a first shell 21, a second shell 22, and a plurality of elastic members 23. The second shell 22 is movably connected to the first shell 21 to allow relative movement therebetween. For example, the second shell 22 may move toward or away from the first shell 21, or the first shell 21 may move toward or away from the second shell 22. However, the two shells do not separate. A plurality of elastic members 23 are disposed between the first shell 21 and the second shell 22, and the elastic members 23 maximize the distance between the two shells without external force. In the present embodiment, the second shell 22 has a larger outer diameter than the first shell 21.The second shell 22 has an annular shape and is connected to the first shell 21 in a conical arc shape, the suction cup body 41 being fixed to the central area of the first shell 21, and the magnetic surface adhesion assembly 30 surrounds the periphery of the suction cup body 41 and is fixed in the second shell 22. Thus, when an external force is applied to the first shell 21, the first shell 21 moves downward and . causes the suction cup body 41 to fit against the contact surface.

[0043] In the present invention, the shell assembly 20 also comprises a partition wall 24, which is locked to an end surface of the first shell 21 facing the direction of the second shell 22. As shown in [Fig. 3], the partition wall 24 has a plurality of positioning rods 241 toward the direction of the first shell 21, and a plurality of screws 242 are used to partially penetrate the first shell 21 from the outside and be locked to the positioning rods 241, so as to fix the first shell 21 to the partition wall 24, and there is a gap therebetween, and the gap is used to accommodate the release member 42.

[0044] Furthermore, the partition wall 24 has a plurality of recessed first receiving seats 245 facing the second shell 22, and the second shell 22 has a plurality of protruding second receiving seats 222 facing the partition wall 24. The elastic member 23 is a compressible spring. As shown in [Fig. 4], the two ends of the elastic member 23 are respectively located inside the corresponding first receiving seat 245 and outside the second receiving seat 222. Although the first shell 21 and the partition wall 24 can be pressed downward, when the external force disappears, the elastic member 23 can be used to restore the distance between the first shell 21 and the second shell 22 to the maximum, or make both maintain an appropriate stiffness.

[0045] The following describes how the present invention ensures that the first shell 21 and the second shell 22 can move relative to each other without being separated. As shown in Figures 2, 3 and 5, a plurality of guide rods 221 are provided on the second shell 22 facing the direction of the partition wall 24. The guide rods 221 can slide through the partition wall 24 without separation, so that the second shell 22 can move closer to or further away from the first shell 21 with the help of the plurality of guide rods 221. In the present embodiment, the guide rods 221 are four in number and they are distributed at an equal angle on the second shell 22. The partition wall 24 also has a plurality of guide holes 243, and a plurality of limiting screws 244 are provided and locked on the guide rods 221 above the partition wall 24.Since the diameter of the top of the limiting screw 244 is larger than that of the guide hole 243, and the diameter of the guide rod 221 is smaller than that of the guide hole 243, the guide rod 221 can thus move in the guide hole 243 without separation. The second shell 22 can move toward or away from the first shell 21 smoothly by using the guide rods 221 at different positions.

[0046] The magnetic surface adhesion assembly 30 is an object having a magnetic attraction force, such as a magnet. The number of magnets may be plural and they are arranged in an annular shape. However, in the present embodiment, the magnetic surface adhesion assembly 30 consists of a single magnet having the shape of a circular ring. The second shell 22 is formed with a concave annular groove 223 on the end surface away from the first shell 21. The magnetic surface adhesion assembly 30 is installed in the annular groove 223. The second shell 22 also has a flexible pad 224. The flexible pad 224 is used to seal the annular groove 223 so that the magnetic surface adhesion assembly 30 is hidden in the second shell 22. The magnetic surface adhesion assembly 30 is distributed around the periphery of the suction cup body 4L

[0047] The suction cup assembly 40 comprises the suction cup body 41 and the release member 42. The release member 42 is used to contact the upper surface of the suction cup body 41 near the edge and lift it, thereby releasing the vacuum surface adhesion state. The suction cup body 41 is a conical sheet which may be made of rubber or other soft materials. The suction cup body 41 has at its center a traction member 411 projecting upwardly. In the present embodiment, the traction member 411 is fixed in the center of the partition wall 24, and an assembly hole 246 is provided in the center of the partition wall 24. When assembling, the traction member 411 protrudes from the partition wall 24 through the assembly hole 246, then a connecting pin 412 penetrates the traction member 411, and the suction cup body 41 is fixed to the partition wall 24.

[0048] As shown in Figures 3 and 6, the suction cup body 41 has a protruding member 413 on the upper surface of the contact edge. In the present embodiment, the protruding member 413 is an inverted U-shaped shell. This shape and position correspond to those of the release member 42. The partition wall 24 has an opening 247 at a corresponding position, and the protruding member 413 is located in the opening 247 or protrudes from the opening 247. The release member 42 is an object that is limited within the shell assembly 20 and can only cause the protruding member 413 to move. More specifically, the first shell 21 has a window 211, and the release member 42 is configured to be within the window 211 and is limited to moving only a short distance in the space between the partition wall 24 and the first shell 21.Furthermore, the release member 42 has a hook 421 facing downward (as the direction of the suction cup body 41). After assembly, the hook 421 can extend into the opening 247. When an external force is applied to . the release member 42 and moves toward the center of the suction cup body 41, i.e., toward the pull member 411, the hook member 421 contacts the protruding member 413 during the movement, thereby causing the edge of the suction cup body 41 to separate from the contact surface to release the vacuum surface adhesion state. Therefore, the position of the protruding member 413 in the opening 247 must be within the movement path of the hook 421.

[0049] To ensure the stability of the release member 42 during movement and its ability to return to its initial position after the disappearance of the external force, the suction cup assembly 40 further comprises at least one spring 43. The partition wall 24 comprises at least one upwardly projecting stopper 248 and two guide pieces 249. The distance between the two guide pieces 249 corresponds to the width of the release member 42. As shown in Figures 2 and 3, the lower part of the release member 42 is formed with at least one guide groove 422. After assembly, the release member 42 is limited between the two guide pieces 249, and the stopper 248 and the spring 43 are located in the guide groove 422. Thus, the release member 42 can only move toward the direction of the center of the suction cup body 41 and will not be separated from the partition wall. separation 24.In the absence of external force, the elasticity of the spring 43 causes the release element 42 to be in the position furthest from the traction element 411.

[0050] Next, an explanation will be given on the actual operation of the present invention. As shown in [Fig.7], when the fixing device 10 is used, the fixing device 10 is first placed on a contact surface 51 of a metal object 50. The contact surface 51 is preferably a flat and smooth surface. The magnetic surface adhesion assembly 30 and the contact surface 51 produce a preliminary magnetic fixing effect by magnetic attraction.

[0051] As shown in [Fig.8], an external force is then applied to the first shell 21, and the partition wall 24 causes the position of the suction cup body 41 to continuously lower. During the lowering process, the air in the space between the suction cup body 41 and the contact surface is expelled, causing a negative pressure vacuum surface adhesion state to be established between the suction cup body 41 and the contact surface 51.

[0052] It should be noted that, as shown in [Fig.9], when the external force disappears, the elastic restoring force of the elastic member 23 pushes the partition wall 24 to move upward as much as possible, and synchronously causes the traction member 411 to rise. This generates a negative pressure vacuum surface adhesion force between the central area of the suction cup body 41 and the contact surface 51. As shown in the Figure, sometimes it is sufficient to generate a very small gap in the central area of the suction cup body 41 to ensure and maintain the required empty surface adhesion state. Apparently, this force also has the same effect when the fixing device of other electronic equipment is installed on the upper surface of the first shell 21 of the present invention.

[0053] As shown in [Fig. 10], when the fixing device 10 is to be removed, the vacuum surface adhesion state must first be released. First, an external force is applied to cause the release member 42 to move toward the pull member 411. During the movement, the hook member 421 contacts the protruding member 413. As the protruding member 413 continues to move, the edge of the suction cup body 41 is pushed back. The contact surface 51 allows outside air to enter the central area of the lower surface of the suction cup body 41, thereby releasing the vacuum surface adhesion state. Then, an external force is applied to the shell assembly 20 and overcomes the magnetic force of the magnetic surface adhesion assembly 30, so that the entire fastener 10 can be removed from the contact surface 51.

[0054] As shown in [Fig. 1 1], which is a schematic view of the actual product of the present invention, reference should also be made to [Fig. 3]. The outer wall of the first shell 21, remote from the second shell 22, has a connecting portion 212. The connecting portion 212 may be a variety of deformation structures, grooves, or shapes. It is used to work with a docking structure of an external device. As shown in [Fig. 10], a pair of docking sockets 60 have been provided therein. With the docking socket 60, the present invention can be installed on the hands-free holder of the mobile phone and for fixing a mobile phone by the fixing device 10 by magnetic surface adhesion and vacuum suction.

[0055] Although the present invention has been described with reference to preferred embodiments thereof, it will be apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention.
