[0025] The utility model is further illustrated below in combination with specific embodiments and drawings.

[0026] As shown in Figures 1-7 The utility model discloses a switch hinge structure with damper module, which comprises a hinge lower seat 1, a damper module 2 and a lock piece 3.

[0027] The damper module 2 is a damper without shell, which is installed in the hinge lower seat 1, that is, the hinge lower seat 1 is used as the shell to form the damper structure with the damper module 2. The lock piece 3 is installed on the upper end of the hinge lower seat 1 to limit the damper module 2 in the hinge lower seat 1, and the upper end of the damper module 2 passes through the lock piece 3 and extends out of the upper end of the hinge lower seat 1 to be connected with the upper cover or other parts needing rotation.

[0028] Specifically, the hinge lower seat 1 is generally made of metal material (for example, stainless steel, zinc alloy, etc.), and a plurality of hanging ears 11 are integrally formed on the outer side of the hinge lower seat 1, wherein the hanging ear 11 is provided with a mounting hole 111, and the hinge lower seat 1 is an inner hollow structure, that is, the hinge lower seat 1 is provided with an installation cavity 12 for installing the damper module 2 along the upper end thereof.

[0029] The damper module 2 includes a spindle 21 inserted into the mounting cavity 12 and rotatable, a first oil seal 22 and a second oil seal 23 mounted on the outside of the spindle 21 and in sealing contact with the inner wall of the mounting cavity 12, and a first sealing ring 24 sleeved on the spindle 21 and in sealing contact with the inner wall of the mounting cavity 12. The first oil seal 22 and the second oil seal 23 divide the mounting cavity 12 to form a first damping cavity and a second damping cavity. Both the first damping cavity and the second damping cavity are filled with damping grease. The locking member 3 is installed at the upper opening of the hinge lower seat 1 and confines the damper module 2 within the mounting cavity 12 of the hinge lower seat 1. The upper end of the spindle 21 passes through the locking member 3 and extends out of the lower end of the hinge lower seat 1. In other words, this invention eliminates the outer shell of the damper and uses a damper module 2 without an outer shell, replacing the outer shell with a hinge base 1. That is, the hinge base 1 serves as the outer shell to form a damper structure with the damper module 2. This reduces the mold manufacturing cost associated with using an outer shell and also reduces the space occupied, allowing the hinge base 1 to be made smaller. This achieves miniaturization and compactness of the structure, further reducing space and cost, and can be applied to structures requiring limited space. Furthermore, this invention replaces the rotating shaft with the core shaft of the damper module to form an independent damped switch hinge structure. During installation, simply attach the lug 11 tightly to the top cover and screw it through the mounting hole 111 to the top cover for connection. Installation is simple, eliminating the need to install a small damper separately in an invisible or difficult-to-see space.

[0030] During operation, the upper end of the mandrel is fixedly inserted into the mounting groove of the housing, and the lower hinge seat 1 is assembled with the upper cover via the lug 11, thus completing the hinged installation of the upper cover and the lower housing. When the upper cover rotates relative to the housing (e.g., falls), the upper cover drives the mandrel of the damper module to rotate. When the mandrel rotates, it drives the first oil seal 22 and the second oil seal 23 on its outer side to rotate. When the first oil seal 22 and the second oil seal 23 rotate, they squeeze and push the damping grease, so that they are resisted by the damping grease, thereby reducing the rotation speed of the mandrel, achieving the purpose of damping, and causing the upper cover to fall slowly relative to the housing.

[0031] The longitudinal section of the lug 11 is inverted L-shaped, which can better fit and assemble with the upper cover. The upper end of the lug 11 is also formed with an arc-shaped positioning part 112. The positioning part 112 is distributed on the outside of the upper end of the spindle 21, and the inner side of the positioning part 112 is connected to the inner wall of the upper opening of the mounting cavity 12 in the hinge lower seat 1. The positioning rib 113 will not affect the normal use of the upper opening of the mounting cavity 12 in the hinge lower seat 1, so that the lock 3 can be disassembled normally. The positioning part 112 of the lug 11 is used to cooperate with the upper cover, so that the present invention can be assembled with the upper cover more stably.

[0032] In addition, the hanging ear 11 is provided with a positioning rib 113 outside, the size of the positioning rib 113 gradually increases from the upper end to the lower end, the upper end of the positioning rib 113 is flush with the upper end opening of the mounting cavity 12 in the hinge lower seat 1, and the positioning rib 113 is used for embedding the positioning groove of the upper cover, so that the hinge can be more stably assembled with the upper cover, and the structural firmness and stability are improved.

[0033] In order to prevent the mandrel 21 from excessive rotation and improve the damping effect, the following design is made: the inner wall of the mounting cavity 12 is provided with first and second blocking columns 121 and 122 which are spaced and used for limiting the rotation angle of the mandrel 21, and gaps are formed between the outer walls of the first and second blocking columns 121 and 122 and the outer wall of the mandrel 21. When the mandrel rotates, the first and second oil seals 22 and 23 outside the mandrel will rotate, and the first and second oil seals 22 and 23 will extrude and push the damping grease when rotating. The damping grease is blocked by the first and second blocking columns 121 and 122, thereby improving the damping effect and better reducing the rotation speed of the mandrel. The damping grease also passes the first and second blocking columns 121 and 122 to the other side of the first and second blocking columns 121 and 122, so that the maximum rotation angle of the mandrel is that the first and second oil seals 22 and 23 respectively contact the first and second blocking columns 121 and 122. When the mandrel is reversely rotated, the damping grease also passes the first and second blocking columns 121 and 122 to one side of the first and second blocking columns 121 and 122.

[0034] The following is the specific assembly structure of the hinge lower seat 1 and the lock piece 3.

The lock piece 3 is provided with an external thread 32 outside, and the lock piece 3 is screw-fixed by the external thread 32 and the internal thread 123. The assembly structure is simple, the connection is stable, the hinge forms a product with higher quality, and the lock piece 3 is partially or completely immersed in the upper end opening of the hinge lower seat 1, which does not affect the use of other structures.

[0036] In order to more conveniently disassemble and assemble the lock piece 3, a corresponding first tool groove 33 and a second tool groove 34 are arranged on the upper end of the lock piece 3, and the first tool groove 33 and the second tool groove 34 can communicate with the central hole 31. In specific use, the staff can use a tool to cross the upper end of the mandrel 21 to simultaneously insert the first tool groove 33 and the second tool groove 34, and rotate the tool, so as to drive the lock piece 3 to rotate, thereby facilitating the disassembly and assembly of the lock piece 3.

[0037] The lower end of the lock piece 3 is provided with a first ring groove 35, and a second sealing ring 36 is arranged in the first ring groove 35, which is in sealing contact with the inner wall of the mounting cavity 12, thereby improving the sealing performance of the assembly structure.

[0038] In order to prevent the mandrel 21 from being driven when the lock piece 3 is disassembled, the mandrel 21 is provided with a step 211 protruding outward in the middle, and a gasket 212 is arranged on the upper part of the mandrel 21 and abuts against the step 211. The lower end of the lock piece 3 abuts against the upper end surface of the gasket 212, so that the lock piece 3 is separated from the mandrel 21 by the gasket 212, which serves to separate the rotation, so that the mandrel 21 is not driven when the lock piece 3 is disassembled.

[0039] In order to improve the stability and rotation stability of the assembly structure of the mandrel 21, the lower end of the mandrel 21 is formed with a shaft 213 with a smaller size, and the outer surface of the shaft 213 is provided with an oil storage groove 214. The bottom of the mounting cavity 12 is provided with a shaft groove 124, and the shaft 213 is pressed into the shaft groove 124, so that the lower end of the mandrel 21 and the bottom of the mounting cavity 12 form a rotatable assembly structure. An oil storage space is formed between the oil storage groove 214 and the shaft groove 124, and damping grease is filled in the oil storage space. The damping grease also serves as a lubricant, which can improve the smoothness of the rotation of the mandrel 21, avoid wear, and reduce or eliminate friction noise.

[0040] The assembly structure of the mandrel 21, the first oil seal 22 and the second oil seal 23 is as follows: the outer side of the mandrel 21 is provided with a first mounting protrusion 215 and a second mounting protrusion 216. The first mounting protrusion 215 is provided with a plurality of first clamping grooves 201, and the first oil seal 22 is provided with a plurality of first buckles 221.
