[0034] See Figure 1-3 , is a hidden snap fastener structure of this embodiment, used to connect the upper plate 100 and the lower plate 200, wherein the upper plate 100 has a through hole; wherein the hidden snap fastener structure includes:

[0035] The body 1 is provided with a first end and a second end in the axial direction, the second end to the first end has a first direction, and the first end to the second end has a second direction, the body encloses a cavity, the opening of the cavity is provided at the first end of the body, and the second end of the body 1 is connected to the lower plate; wherein, the first end of the body 1 is provided with a first protrusion 11a and a second protrusion 11b, the first protrusion 11a gradually extending outward from the outer side wall of the first end of the body 1; the second protrusion 11b gradually extending inward from the inner side wall of the first end of the body 1;

[0036] The support mechanism 2 includes an elastic component 21 and a support body 22. The elastic component 21 and the support body 22 are installed in the cavity. The elastic component 21 has a first end and a second end opposite to each other. The first end of the elastic component 21 is connected to the second end of the body 1. The second end of the elastic component 21 contacts the support body 22.

[0037] The main body 1 is made of elastic material, the support body 22 is made of magnetic material, and the support body 22 can reciprocate along a first direction, thereby enabling the first end of the main body 1 to expand or contract radially.

[0038] Specifically, see Figure 3 The second protrusion 11 b has a first annular wall 111 for contacting the support body 22 , and the size of the first annular wall 111 gradually increases along the first direction.

[0039] In the first state, the support body 22 is lifted by the elastic member 21 and abuts against the first annular wall 111, and the first end of the body 1 is opened. At this time, the outer dimension of the first protrusion 11a is larger than the dimension of the through hole;

[0040] In the second state, the support body 22 is attracted by the magnet on the side of the lower plate 100 facing away from the support body 22, and the support body 22 moves along the second direction. The support body 22 is separated from the first annular wall 111, and the first end of the main body 1 retracts. At this time, the size of the first protrusion 11a is smaller than the size of the through hole.

[0041] For the above structure, during installation, the operator first pre-fixes the second end of the body 1 to the upper surface of the lower plate 200 facing the upper plate 100, so that the first end of the body 1 is placed toward the lower plate 200. Then, the through-hole position of the upper plate 100 is placed toward the first end of the body 1. During this process, the upper plate 100 can be installed in two ways. The first method is to place a magnet on the side of the lower plate 200 facing away from the upper plate 100. Since the support body 22 of the support mechanism 2 is set to a magnetic material, the magnet generates a magnetic force on the support body 22, and the support body 22 generates a movement along the second direction. The elastic component 21 is pressed down and deformed by the support body 22 in the second direction. Since the first end of the main body 1 is separated from the support of the support body 22, it retracts to its initial state, so that the outer diameter of the support body 22 becomes smaller. Therefore, the first end of the main body 1 can pass through the through hole of the upper plate 100 without hindrance. After the entire first end of the main body 1 passes through the upper plate 100, the magnet can be removed. The support body 22 that loses the magnetic attraction is pushed up again in the first direction by the elastic component 21 until it conflicts with the first annular wall 111 of the second protrusion 11b, and the first end of the main body 1 is pushed open, so that the size of the first protrusion 11a is larger than the inner diameter of the through hole of the upper plate 100, so that the upper plate 100 is limited by the first end of the main body 1, and the installation of this method is completed. In the second method, the first protrusion 11a is provided with a second annular wall 112 for contacting the inner wall of the through hole, and the second annular wall 112 gradually increases in size along the second direction. During installation, the second annular wall 112 can be directly contacted with the inner wall of the through hole, and the upper plate 100 is continuously applied to the lower plate 200. The inner wall of the through hole of the upper plate 100 slides and rubs against the second annular wall 112 of the first protrusion 11a, and in this process, the body 1 is deformed, the first protrusion 11a is squeezed, and the first annular wall 111 abuts the support body 22 along the second direction. The pressure causes the support body 22 to displace along the second direction, the elastic component 21 to deform along the second direction, and the size of the first protrusion 11a is reduced until the first end of the main body 1 is completely passed through the through hole of the upper plate 100. At this time, there is no limitation of the through hole of the upper plate, and the support body 22 is pushed up again along the first direction by the elastic component 21. The first end of the main body 1 expands again, so that the size of the first protrusion 11a is larger than the inner diameter of the through hole of the upper plate 100, so that the upper plate 100 is limited by the first end of the main body 1, and the installation of this method is completed. The above two installation methods can be selected according to actual needs.If it is necessary to separate the upper plate 100 from the lower plate 200, it is necessary to place a magnet on the side of the lower plate 200 facing away from the upper plate 100, away from the same as above, in the first state where the support body 22 is pressed down and the first end of the main body 1 is opened. At this time, since the size of the first protrusion 11a is smaller than the through hole size of the upper plate 100, the first end of the main body 1 loses its limit on the upper plate 100, and the upper plate 100 can be easily removed.

[0042] During the above use, the control magnet can realize the up and down displacement of the support body 22, so that the size of the first protrusion 11a can be changed as needed, thereby realizing the rapid switching between the limiting and releasing states of the upper plate 100 - the first state Figure 2 and the second state Figure 1 , making the installation between the upper plate 100 and the lower plate 200 easier.

[0043] Further, if Figure 2 As shown, in another embodiment, the first protrusion 11a is provided with a third annular wall 113 for abutting against the inner wall of the through hole. The third annular wall 113 gradually increases in size along the first direction. The third annular wall 113 is provided on the side of the second annular wall 112 facing the second end of the body 1. Through the provision of the third annular wall 113, in some cases, when the upper plate 100 is separated from the first end of the body 1 and the upper plate 100 moves in the first direction, the third annular wall 113 may slide against the inner wall of the through hole of the upper plate 100. The third annular wall 113 plays a guiding role for the upper plate 100, and the first end of the body 1 can be smoothly squeezed and retracted by the inner wall of the through hole of the upper plate 100, thereby avoiding the accidental situation in which the support body 22 fails to move in the second direction in time due to insufficient magnetic attraction force when the magnetic support body 22 is attracted.

[0044] Furthermore, the first raised portion 11a further includes a fourth annular wall 114 extending axially between the second annular wall 112 and the third annular wall 113. The provision of the fourth annular wall 114 allows for a smoother transition between the second annular wall 112 and the third annular wall 113, preventing damage to the upper plate 100 by the first raised portion 11a. Furthermore, the structure of the first raised portion 11a itself allows for a smaller amount of bevel cutting, making it easier to machine and reducing component costs.

[0045] Further, if Figure 4As shown, the second end of the body 1 has a rivet portion 12, so that the lower plate 200 can be riveted and fixed to the second end of the body 1. Specifically, when connecting the lower plate 200 to the body 1, axial pressure can be applied between the lower plate 200 and the body 1, so that part of the material of the lower plate 200 at the rivet portion 12 is deformed and released, forming a stable riveted fixation between the lower plate 200 and the body 1.

[0046] In another embodiment, Figure 5 As shown, the second end of the body 1 has a piercing rivet 13, so that the lower plate 200 can be self-pierced and fixed to the second end of the body 1. Specifically, the slot is configured to have a certain curvature. During the process of inserting the piercing rivet 13 into the lower plate 200, the piercing rivet 13 is squeezed into the lower plate 200, ultimately achieving fixation between the piercing rivet 13 and the lower plate 200, and generating a large tensile force between the two.

[0047] Of course, the connection method between the lower plate 200 and the second end of the main body 1 is not limited to the above-mentioned riveting and insertion, but also includes SMT welding, gluing, riveting, etc., as long as effective fixation between the lower plate 200 and the second end of the main body 1 can be achieved.

[0048] Furthermore, in this embodiment, the support body 22 is configured as a sphere, and the cavity is configured as a cylindrical space slightly larger than the diameter of the sphere to facilitate smooth movement of the sphere. Of course, in another embodiment, the shape of the support body 22 is not limited to a sphere. As long as it can effectively resist the body 1 and provide support, it can be a cylindrical or annular shape without departing from the concept of the present invention.
