[0002] In daily life, cabinet doors are usually designed with an upward-opening structure, typically supported by hydraulic struts or elastic hinges. However, when the cabinet door is opened using this structure, it flips directly to the top. Since people of different heights have different heights, it is very inconvenient for shorter people to close the cabinet door because it flips directly to the top. Therefore, how to make the cabinet door open at any angle within a certain range to meet the needs of people of different heights and make it easy to close the door is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A support mechanism with adjustable support force, comprising:

[0006] A base having a receiving cavity, wherein a first mounting position is provided on the base;

[0007] A first bracket is rotatably mounted on the base, and a first hinge point is provided between the first bracket and the base. A second mounting position is provided on the first bracket.

[0013] In some embodiments, the first connector is provided with a first limiting post, and the base is provided with a first limiting groove adapted to the first limiting post. The first limiting post is movably inserted into the first limiting groove, and the first limiting groove has a preset length.

[0014] In some embodiments, a first screw is also included, which is rotatably mounted on the base. The first slider is provided with a first threaded hole adapted to the first screw, and the first slider is movably mounted on the first screw through the first threaded hole.

[0031] The present application will be further described in detail below with reference to the accompanying drawings. In the description of the embodiments, unless otherwise stated, the terms "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the present application must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present application.

[0032] like Figure 1 and Figure 2As shown, this utility model provides an adjustable support mechanism, which mainly includes a base 100, a first bracket 200, a first slider 101, a second slider 102, and a first elastic element 104.

[0033] Specifically, the base 100 has a receiving cavity, and a first mounting position is provided on the base 100. In this embodiment, for example... Figure 3 As shown, the base 100 is formed by snapping together a first housing 1001 and a second housing 1002. A through first fixing hole 103 is provided on both the first housing 1001 and the second housing 1002 to facilitate the rotation and fixing of the base 100. The first fixing hole 103 is located at one end of the base 100, near the edge.

[0034] The first bracket 200 is rotatably mounted on the other end of the base 100. A second fixing hole 201 is provided on the other end of the base 100. The first bracket 200 is rotatably mounted on the second fixing hole 201 via a pin, forming a first hinge point. The second fixing hole 201 is located close to the other end of the base 100, thereby ensuring the distance between the first fixing hole 103 and the second fixing hole 201, forming a large rotation radius. A second mounting position 202 is provided on the other end of the first bracket 200 for rotatably connecting with an external structure. In this embodiment, the second mounting position 202 can be a pin structure or a hole structure.

[0035] The first slider 101 is disposed within the receiving cavity of the base 100. The first slider 101 can reciprocate linearly within the base, and the direction of movement is the length direction of the base 100. The second slider 102 is movably disposed within the receiving cavity of the base 100. The second slider 102 can reciprocate linearly relative to the base 100. The second slider 102 abuts against one end of the first support 200. The rotation of the first support 200 relative to the base 100 drives the second slider 102 to move linearly. A first elastic element 104 is disposed between the first slider 101 and the second slider 102. One end of the first elastic element 104 abuts against the first slider 101, and the other end of the first elastic element 104 abuts against the second slider 102. In the initial state, that is, when the angle between the first support 200 and the base 100 is the smallest, the first elastic element 104 is in a natural state or a compressed state.

[0036] Preferably, the first elastic element 104 is a spring, and the outer diameter of the spring matches the size of the receiving cavity, thereby ensuring that the spring will not bend during compression. Optionally, the first elastic element 104 may also be a metal spring sheet structure.

[0037] In this embodiment, a first slider 101 is provided. By adjusting the position of the first slider 101 relative to the base 100, the first elastic member 104 is squeezed, thereby increasing the elastic force of the first elastic member 104 on the second slider 02. When the first support 200 rotates and drives the second slider 102 to move and squeeze the first elastic member 104, its corresponding elastic force increases, thereby realizing different support forces of the first support 200 to meet the adjustment of different angles of the first support 200 relative to the base 100.

[0038] In one embodiment, to improve the stability of the connection structure between the first support 200 and the second slider 102, a first connector 300 is further included. A first fixed shaft 301 is provided on the first connector 300, and a corresponding fixing hole is provided on the first support. This allows the first connector 300 to be rotatably positioned at the end of the first support 200 near the base, with one end of the first connector 300 abutting against the second slider 102. By providing the first connector 300, when the first support 200 rotates, it drives the first connector 300 to rotate, thereby pushing the second slider 102 to move. This reduces the distance between the contact section between the first support 200 and the second slider 102 and the rotation point of the first support 200, thus reducing the size of the device.

[0039] Furthermore, such as Figure 4 As shown, to ensure the stability of the transmission structure of the first connector 300, multiple first locking teeth 302 are provided on the first connector 300, and multiple matching first locking slots 1021 are provided on the second slider 102. The first locking teeth 302 are engaged in the first locking slots 1021. When the first connector 300 rotates, the cooperation between the first locking teeth 302 and the first locking slots 1021 makes the transmission structure between the second slider 102 and the first connector 300 more stable. When the first bracket 200 rotates relative to the base 100, a first locking tooth 302 will be engaged in the first locking slot 1021, satisfying the movable contact between the two without slippage during transmission.

[0040] Alternatively, as another variation of this embodiment, the first locking tooth 302 can be disposed on the first slider 102, and the first locking groove 1021 can be disposed on the first connector 300, which can also achieve the above purpose.

[0041] In one embodiment, to limit the angle between the first bracket 200 and the base 100 and prevent the angle from being too large, a first limiting post 303 is provided on the first connector 300, and a first limiting groove 107 corresponding to the position is provided on the inner wall of the first housing 1001 and the second housing 1002 of the base 100. Figure 7As shown, the first limiting post 303 is movably inserted into the first limiting groove 107. In this embodiment, the first limiting groove 107 has a preset length, thereby allowing the first bracket 200 to rotate relative to the base 100 within a certain range of angles. Furthermore, there are two first limiting grooves 107 and two first limiting posts 303, arranged symmetrically. The first limiting posts 303 are located on both sides of the first connector 300, and the first limiting grooves 107 are located on the first housing 1001 and the second housing 1002, respectively.

[0042] Alternatively, the first limiting groove 107 can be disposed on the first connecting member 300, and the first limiting post 303 can be disposed on the first housing 1001 and the second housing 1002, which can also achieve the above purpose.

[0043] In one embodiment, such as Figure 3 and Figure 5 As shown, to facilitate the reciprocating linear movement of the first slider 101, a first screw 106 is also included within the base 100. The first screw 106 is rotatably disposed within the base 100. A first threaded hole is provided on the first slider 101, which is adapted to the outer diameter of the first screw 106. The first slider 101 is movably disposed on the first screw 106 through the first threaded hole. In this embodiment, the reciprocating linear movement of the first slider 101 is achieved by rotating the first screw 106 in both directions.

[0044] Furthermore, a first adjusting head 1061 is provided on the first screw 106, and a plurality of evenly spaced first adjusting grooves 1062 are provided on the first adjusting head 1061. A first adjusting hole 105 is provided on the base 100, and the position of the first adjusting hole 105 corresponds to the position of the first adjusting head 1061. The axis of the first adjusting hole 105 is perpendicular to the axis of the first screw 106. In this embodiment, by providing the first adjusting hole 105, an external tool such as a screwdriver can be inserted into the first adjusting hole 105. By rotating the screwdriver to engage with the first adjusting grooves 1062, the first screw 106 is driven to rotate, thereby causing the first slider 101 to move relative to the first screw 106. In this embodiment, the engagement between the first adjusting groove 1062 and the screwdriver is based on the same principle as the engagement of two bevel gears to change the direction of force transmission, which will not be elaborated further here. It should be particularly noted that the first screw 106 only rotates relative to the base 100 and does not move along its own axis. For example, by locking the first adjusting head 1061, only the first screw 106 can rotate relative to the base 100.

[0045] Alternatively, the axis of the first adjusting hole 105 can be set collinearly with the axis of the first screw 106. In this case, the structure of the first adjusting groove 1062 is similar to the cross groove structure of the screw head, thereby realizing the rotation of the first screw 106.

[0046] Alternatively, the rotation structure of the first screw 106 can also be controlled by an electric structure. For example, the rotation of the first screw 106 can also be achieved by connecting the first screw 106 to the output shaft of a micro motor.

[0047] In one embodiment, to facilitate the operator's understanding of the supporting force of the first support 200, a first scale line 108 is provided on the base 100, such as... Figure 6 As shown, a first indicator block 1011 is provided on the first slider 101. The first indicator block 1011 can coincide with multiple marks on the first scale line 108. The first indicator block 1011 protrudes relative to the base 100. By observing the position of the first indicator block 1011 corresponding to the first scale line 108, the operator can accurately determine the position of the first slider 101, thereby determining the squeezing force exerted by the first slider 101 on the first elastic member 104, and thus confirming the supporting force transmitted by the first elastic member 104 to the first support 200 through the second slider 102. For example, when the first slider 101 is closer to the second slider 102, the first elastic member 104 is compressed. When the first support 200 rotates, a greater force is needed to move the second slider 102 towards the first slider 101, thereby providing a greater supporting force to the first support 200. In this embodiment, the first elastic element 104 is preferably a spring. The elastic force provided by the spring is the spring elastic coefficient multiplied by the amount of spring compression. The closer the first slider 101 is to the second slider 102, the shorter the spring is compressed. When the first support 200 rotates and drives the second slider 102 to move, the force required for the second slider 102 to compress within a unit degree is greater, that is, the feedback to the first support 200 is a larger supporting force.

[0048] Alternatively, the base 100 can be made transparent at the position corresponding to the first slider 101. In this case, the first indicator block 1011 does not need to protrude relative to the base 100. A position edge line can be set on the first slider 101, and the position mark can be aligned with the first scale line 108.

[0049] In one embodiment, in order to enable the first slider 101 to reciprocate linearly relative to the base 100, a first limiting boss 1012 is provided on the first slider 101, and a corresponding first limiting groove is provided on the base. The first limiting boss 1012 is engaged in the first limiting groove, and the first limiting groove is provided along the length direction of the base 100.

[0050] Optionally, the first limiting groove can be disposed on the first slider 101, and the first limiting boss 1012 can be disposed on the inner wall of the base 100. Optionally, the first slider 101 can be disposed in a non-circular irregular shape, such as a rectangular, triangular, or pentagonal cross-section, and the receiving cavity of the base 100 can be configured to fit the first slider 101, thus enabling the first slider 101 to move only in a straight line. Further, a second limiting structure is provided between the second slider 102 and the base 100, a second limiting boss 1022 is provided on the second slider 102, and a corresponding second limiting groove is provided on the base 100, so that the second slider 102 can move reciprocally in a straight line relative to the base. The principle of the first limiting structure and the second limiting structure is the same, as described above, and will not be elaborated further here.

[0051] In one embodiment, such as Figure 8 As shown, this support mechanism is applied to the cabinet door 400. One end of the first bracket 200, which has a second mounting position 202, is rotatably connected to the cabinet door 400. The base 100 is rotatably connected to the cabinet body through a first fixing hole 103. When the first bracket 200 is in an open state relative to the base 100, the angle between the first bracket 200 and the base 100 is not less than 25 degrees. When the angle between them is less than 25 degrees, the cabinet door 400 is closed. When the angle between them is greater than 25 degrees, the cabinet door 400 can be adjusted outwards to any angle. It should be noted that the maximum opening angle of the cabinet door 400 is when the angle between the first bracket 200 and the base 100 is at its maximum. The supporting force of the first bracket balances the weight of the cabinet door, thus ensuring that the cabinet door is at the desired opening angle.

[0052] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model. These improvements and modifications should also be considered within the scope of protection of this utility model.
