DETAILED DESCRIPTION

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Secondly, the utility model is described in detail with reference to the schematic diagram. When describing the embodiments of the utility model, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagrams are only examples, which should not limit the scope of protection of the utility model. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0030] Example 1

[0031] Reference Figure 1-5 , which is the first embodiment of the utility model, and this embodiment provides a lightweight and high-strength soundproof door, comprising the following parts:

[0032] A door frame 1 and a door leaf 2 are matched with each other, and a door handle 3 is movably mounted on the door leaf 2, so as to be used for hand-holding or cooperating with a door lock to open and close the door;

[0033] The pushing mechanism 4 is used so that the door leaf 2 can obtain a thrust from the door opening direction or the door closing direction through the pushing mechanism 4;

[0034] The first force-bearing member 5 and the second force-bearing member 6 provided on the door leaf 2 form a linkage with the pushing mechanism 4. When the user applies a push-pull force in the door opening direction and the door closing direction to the door handle 3, the two sides of the door handle 3 will apply force to the first force-bearing member 5 and the second force-bearing member 6 respectively.

[0035] Based on the above, through linkage, the present invention can set such a motion relationship: when the first force-bearing member 5 is subjected to force, the pushing mechanism 4 applies a pushing force in the door opening direction to the door leaf 2, and vice versa, when the second force-bearing member 6 is subjected to force, the pushing mechanism 4 applies a pushing force in the door closing direction to the door leaf 2. Through such a motion relationship, during the use of the present invention, when the user holds the door handle 3 and pushes the door handle 3 in the door opening direction, the door handle 3 applies force to the first force-bearing member 5, so that the pushing mechanism 4 automatically applies a pushing force in the door opening direction to the door leaf 2, thereby cooperating with the user to play a power-assisting effect when opening the door, and vice versa, the same is true when closing the door;

[0036] The utility model automatically provides a power-assisting effect when opening and closing the door, thereby reducing the heavy feeling brought to the user by the heavy structure of the door leaf 2 during the opening and closing process. Compared with the soundproof door in the prior art, it can achieve a certain lightness while maintaining high strength.

[0037] Further, see Figure 1 and Figure 2 The pushing mechanism 4 includes a slider 401 that is slidably arranged relative to the door frame 1 and a push rod 402 that is hinged between the slider 401 and the door leaf 2. The slider 401 can be slidably matched with the door frame 1 by setting a slide groove on the door frame 1. The pushing mechanism 4 also includes a power element 403 that acts on the slider 401, thereby driving the slider 401 to move;

[0038] Based on this structure, when the slider 401 is moved by force, a thrust is formed on the door leaf 2 through the push rod 402, thereby assisting the door leaf 2. This structural design can keep the entire pushing mechanism 4 simple, thereby helping to improve the streamlined effect of the appearance of the utility model.

[0039] Further, see Figure 2 The door leaf 2 is provided with a force-applying end 7, and the push rod 402 is hinged to the force-applying end 7 to achieve the effect of being hinged to the door leaf 2, and a certain distance is formed between the force-applying end 7 and the surface of the door leaf 2;

[0040] This structural feature allows a certain distance between one end of the push rod 402 and the surface of the door leaf 2, so that the push rod 402 and the surface of the door leaf 2 form a certain angle, which helps to better form a thrust on the door leaf 2.

[0041] Further, see Figure 2 and Figure 3 , with respect to the form of the power element 403, the utility model further comprises a guide member 8 fixedly arranged relatively to the door frame 1 along the moving path direction of the slider 401, which has magnetism. Figure 3 As shown in , a columnar magnetic block can be used, the power element 403 includes a winding 403a fixedly arranged on the slider 401, a through area is provided on the slider 401, the winding 403a is located in the through area, so that the guide member 8 can also directly pass through the through area, so that the winding 403a forms a sleeve on the guide member 8, and the winding 403a is also provided with a power supply module, which is used to be linked with the first force-bearing member 5 and the second force-bearing member 6;

[0042] Based on this, when the winding 403a is energized by the power supply module, a magnetic field is formed, thereby cooperating with the guide 8 to form a mutual thrust, causing the slider 401 to slide, and its sliding direction is determined by the force direction of the winding 403a, that is, it is determined by the direction of the current provided to the winding 403a.

[0043] Further, see Figure 4 and Figure 5 , as for the coordination mode between the first force-bearing member 5, the second force-bearing member 6 and the door handle 3, specifically, the first force-bearing member 5 includes a first push switch 501, the second force-bearing member 6 includes a second push switch 601, the first push switch 501 and the second push switch 601 are both electrically connected to the power supply module, so as to form a linkage with each other. In terms of positional relationship, when the door handle 3 is acted upon by an external force provided by a user, it applies force to the first push switch 501 and the second push switch 601 respectively when it moves relative to the two sides of the door leaf 2 according to two different force application directions provided by the user;

[0044] Based on this, for example, when the user holds the door handle 3 and pushes the door leaf 2 in the direction of opening the door, the door handle 3 presses the first push switch 501, so that the power supply module provides the current in the target direction to the winding 403a through the electrical linkage, so as to complete the sliding of the slider 401 in the predetermined direction, and realize the push rod 402 to provide the door leaf 2 with a thrust in the direction of opening the door. Similarly, when the user holds the door handle 3 to close the door, the process is also the opposite. Through the cooperation of the first push switch 501 and the second push switch 601, the detection process of the activity direction of the door handle 3 is rapid and direct, thereby fully improving the safety of the present invention. sensitivity during operation; and regarding the power supply module, for example, in the utility model, a conventional forward and reverse circuit can be directly configured, the circuit is powered by an external power supply, the main circuit part thereof is connected to the winding 403a, and the control circuit part is connected to the first push switch 501 and the second push switch 601, so that when the first push switch 501 and the second push switch 601 are respectively actuated, the main circuit part can respectively provide two power supply signals with different voltage directions to the winding 403a to form two magnetic fields in different directions, thereby completing the linkage coordination to achieve the simplest linkage effect.

[0045] Further, see Figure 4 and Figure 5, an annular plate 9 is provided on the door handle 3, and the annular plate 9 is coaxial with the main shaft part of the door handle 3, the first push switch 501 and the second push switch 601 are both fixedly connected to the door leaf 2, and respectively contact the two sides of the annular plate 9, so that when the door handle 3 moves in two directions, a force pushing effect can be formed on the first push switch 501 and the second push switch 601 respectively, and the door leaf 2 is also fixedly provided with a spring assembly 10 that respectively contacts the two sides of the annular plate 9;

[0046] Based on this, the cooperation of the annular plate 9 allows the annular plate 9 to always cover the first push switch 501 and the second push switch 601 during the rotation of the door handle 3, so that when the door handle 3 rotates, the door handle 3 can always push the first push switch 501 or the second push switch 601 during the movement relative to the length direction of its own main axis, thereby avoiding deviation. In addition, the setting of the spring assembly 10 ensures that the door handle 3 is always in a fixed position under normal circumstances, thereby not pressing the first push switch 501 and the second push switch 601.

[0047] Further, see Figure 4 and Figure 5 , the annular plate 9 includes a fixed layer 901 and movable layers 902 respectively located on both sides of the fixed layer 901, the fixed layer 901 is fixedly connected to the main shaft of the door handle 3, and the movable layer 902 is rotationally matched with the main shaft of the door handle 3, so as to be used to contact the spring assembly 10, and the two movable layers 902 are also used to contact the first push switch 501 and the second push switch 601 respectively;

[0048] Based on this, the rotation coordination of the movable layer 902 ensures that the door handle 3 will not rotate synchronously with it when it rotates, which is not easy to cause wear of the first push switch 501 and the second push switch 601, and will not cause the spring assembly 10 to swing due to friction, which is beneficial to maintaining the stability of the structure.

[0049] Example 2

[0050] The content of this embodiment is basically the same as that of embodiment 1, except that the power element 403 is used. Figure 6The power element 403 includes a rotating rod 403b that is arranged to rotate relative to the door frame 1, and a driving motor 403c that is configured to cooperate with the rotating rod 403b in transmission. The driving motor 403c can be directly fixed to the door frame 1. The rotating rod 403b is threadedly matched with the slider 401, so that when the driving motor 403c is driven to rotate in two directions respectively, the slider 401 can also achieve sliding movement in two directions. The driving motor 403c is still powered by the power supply module introduced in Example 1. When the driving motor When 403c obtains voltages in two different directions respectively, it can still complete rotation in two directions according to the different current directions; the difference between this embodiment and embodiment 1 is that, in this embodiment, through threaded cooperation, when the entire pushing mechanism 4 is not working, the position of the slider 401 can be locked, thereby achieving the locking effect of the door leaf 2, so as to achieve the locking effect of the entire soundproof door, so that for some doors that are not often opened and closed, as long as the power is cut off, the door leaf 2 can be automatically locked, thereby providing different practical effects.

[0051] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
