Description

Technical Field

[0001] The present invention relates to the technical field of hinges, and particularly to a novel hinge structure that is convenient for disassembly. Background Art

[0002] When an ordinary hinge is in use, it is usually directly fixed to the structure to be installed by screws. This screw fixing method makes the hinge inconvenient to disassemble during use and is prone to affecting its stability when subjected to vibration. Various vibrations generated during the use of the structure to be installed will increase the working burden of the hinge. During the continuous operation of the hinge, it is prone to rapid wear, affecting its normal use. Therefore, it is necessary to coat lubricating oil on the hinge to lubricate the hinge, reduce its wear during operation, extend its service life, and ensure the normal operation of the hinge.

[0003] The existing hinge has a simple structure. For a frequently used hinge structure, the lubricating oil on it is prone to loss and dripping, increasing the consumption of lubricating oil, unable to form an adaptable lubricating effect, and reducing the service life of the hinge; by opening penetration holes on the rotating shaft and the sleeve and connecting the lubricating oil when they rotate and communicate to form lubrication, in this way, during the repeated opening and closing of the hinge, the lubricating oil is prone to leakage and loss through the penetration holes; and it is not convenient to control the rotational resistance of the hinge, reducing the use adaptability and stability of the hinge.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. The present invention provides a lubricating shell and an electromagnet. Under the action of the magnetic field of the electromagnet, the viscosity of the lubricating oil with magnetic fluid characteristics in the lubricating shell is significantly increased and the fluidity is reduced, so that the lubricating oil with increased viscosity cannot pass through the lubricating hole, thereby avoiding the loss of the lubricating oil and effectively avoiding the loss of the lubricating oil through the lubricating hole when the rotating frame is repeatedly opened and closed. When lubrication is needed, during the unfolding process of the rotating frame, the electromagnet is powered off and loses the magnetic field, so that the lubricating oil with magnetic fluid characteristics recovers its original fluidity, which facilitates the lubricating oil to pass through the lubricating hole to lubricate the rotating frame and the mounting seat, thereby improving the lubrication effect on the rotating frame and the mounting seat, and controlling the fluidity of the lubricating oil through the magnetic field to perform adaptive lubrication, thereby avoiding excessive loss of the lubricating oil due to excessive fluidity.

[0020] 2. The present invention sets a lubricating shell, an electromagnet and a magnetic limit assembly. When the rotating frame is in a closed state, the electromagnet is energized to generate a magnetic field to the outside, magnetically attracting the magnetic limit assembly so that its output end clamps the lubricating page of the rotating frame, and indirectly controls the limit column to move in the direction of the electromagnet by controlling the output end of the first electric push rod to contract, driving the magnetic limit assembly to move in the same direction, thereby increasing the contact pressure between the lubricating page of the rotating frame and the limit page of the mounting seat, and increasing the resistance of the contact part between the mounting seat and the rotating frame by increasing the pressure, thereby facilitating the control of the resistance between the rotating frame and the mounting seat, thereby enhancing the adaptability and stability of the hinge.

[0021] 3. The present invention provides a sealing plug and a lubrication hole. When the rotating frame is in a closed state, the lubrication groove is in a sealed space due to the sealing effect of the sealing plug of the rotating frame on the lubrication hole. The limiting leaf of the mounting seat and the lubrication leaf of the rotating frame are in sealed friction contact. The lubrication of the lubrication groove can be obtained for easy use during opening and closing, and excess lubrication will not flow out during closing. The entire hinge structure can be installed and used at different angles. Even if the external temperature changes, it is difficult to affect the lubrication groove area in a sealed state. Moreover, when the contact pressure of the lubrication leaf and the limiting leaf is increased to control the rotation resistance of the two, this part of the resistance mainly comes from the compressed multiple sealing plugs, so the damage to the mounting seat and the rotating frame is also relatively small.

[0022] 4. The present invention sets a supporting mechanism. When the rotating frame rotates, the contact pressure between the supporting column and the fixed page of the rotating frame changes. After the pressure sensor on the rubber plug detects the pressure change, the external chip receives its signal and controls the third electric push rod to work, and finally restores the contact pressure between the supporting column and the fixed page by controlling the movement of the pressure regulating piston, so that the rotating frame is free from the resistance from the supporting column to limit its rotation at any time, thereby improving the stability of the rotating frame during operation.

[0023] 5. The present invention sets a rack, a linkage gear, a belt linkage assembly, a stirring gear, a stirring frame and an elastic shell. When the fourth electric push rod works, its output end drives the rack to reciprocate, thereby driving multiple stirring gears to rotate through the linkage gear and the belt linkage assembly. With the cooperation of the torsion spring, the stirring gear rotates and continuously moves the stirring frame, causing it to hit the elastic shell. Then, under the stirring action of the stirring gear and the stirring frame, and the vibration action of the elastic shell, the magnetic particles precipitated to the bottom of the lubricating shell are evenly distributed, so that the lubricating oil with magnetic fluid characteristics can better play a role under the action of the magnetic field, which is convenient for controlling the fluidity of the lubricating oil at any time according to work requirements for lubrication, and further avoiding excessive loss due to excessive fluidity of the lubricating oil.

Detailed implementation manners

[0039] The following embodiments are only for illustrative purposes and are not intended to limit the scope of the present invention.

[0040] Refer to Figures 1 - 5 , a novel hinge structure that is easy to disassemble, including a mounting base 1. The mounting base 1 includes a buffer page and a limiting page, and the buffer page is fixedly connected to the limiting page. It further includes:

[0041] A rotating frame 2. The rotating frame 2 includes a lubricating page and a fixed page. The lubricating page is fixedly connected to the fixed page. The lubricating page is detachably rotatably connected to the limiting page, and the lubricating page is in sealed rotational contact with the limiting page.

[0042] A lubricating housing 9 is fixedly connected to the lubricating page and contains lubricating oil with magnetorheological fluid characteristics inside. The output end of the lubricating housing 9 is located between the limiting page and the lubricating page. An electromagnet 22 is installed on the buffer page. When the electromagnet 22 is energized, the viscosity of the lubricating oil with magnetorheological fluid characteristics increases. A magnetic moving limiting assembly is connected to the lubricating page, and the magnetic moving limiting assembly abuts and cooperates with the lubricating page when the electromagnet 22 is energized.

[0043] A pad frame 3 is fixedly connected to the outside of the buffer page, and the pad frame 3 is made of an elastic material.

[0044] The pad frame 3 can enable the mounting base 1 to reduce vibration during long-term use, and there is less wear between the mounting base 1 and the mounted component.

[0045] Refer to Figures 2 - 4 、 Figure 6 、 Figure 10 and Figure 13, a clamping convex block 101 and a limiting tube 10 are fixedly connected to the limiting page. A first electric push rod is installed inside the buffer page. The output end of the first electric push rod is fixedly connected to a first moving frame 13. A supplementary frame 15 is fixedly connected to the end of the first moving frame 13 away from the first electric push rod. The supplementary frame 15 is slidably clamped and matched with the clamping convex block 101. A through groove for the movement of the supplementary frame 15 is opened on the limiting page. The limiting tube 10 penetrates through the lubricating shell 9 in a sealed manner and is internally slidably connected to a limiting column 11. A second electric push rod is installed inside the first moving frame 13. The output end of the second electric push rod is fixedly connected to a second moving frame 14. The second moving frame 14 is clamped and matched with the end of the limiting column 11 extending into the inner side of the limiting page.

[0046] Referring to the figure Figure 5 , a clamping groove 201 and a limiting groove 202 are opened on the lubricating page. The supplementary frame 15 is rotationally matched with the clamping groove 201. The limiting groove 202 is arc-shaped, and the center of the arc corresponds to the axis of the supplementary frame 15. The other end of the limiting column 11 extends into the limiting groove 202. A magnetic limiting component is connected to the limiting column 11.

[0047] One side of the clamping groove 201 is penetrated and is in clearance fit with the clamping convex block 101.

[0048] A plurality of balls are connected to the outer side of the supplementary frame 15 by ball heads. The plurality of balls rotate and abut against the inner wall of the clamping groove 201.

[0049] Connected by balls, compared with the rotating frame 2 directly rotating around the supplementary frame 15, the rotation is smoother. The design of the balls also changes the sliding friction into smaller rolling friction.

[0050] Referring to Figures 3 - 5 , a plurality of lubricating grooves 102 are opened on the side of the limiting page close to the lubricating page. A plurality of lubricating holes 103 are communicated inside the lubricating grooves 102. The end of the lubricating hole 103 away from the lubricating groove 102 is communicated with the inside of the lubricating shell 9. A plurality of sealing plugs 203 are fixedly connected to the side of the lubricating page close to the limiting page. The plurality of sealing plugs 203 correspond to the plurality of lubricating holes 103 one by one and seal the lubricating holes 103 in the closed state of the rotating frame 2.

[0051] Referring to Figures 10 - 14, the magnetic motion limit assembly includes an adjustment frame 12 which is slidably connected within a limit post 11. One end of the adjustment frame 12 penetrates through the limit post 11 and extends into the inner side of the limit page, and a first permanent magnet 121 is installed. The first permanent magnet 121 has opposite magnetic poles to the magnetic field generated by the energized electromagnet 22. At the other end of the adjustment frame 12, two second permanent magnets 122 are installed, and the magnetic pole directions of the two second permanent magnets 122 are opposite. One end of the limit post 11 extending into the limit slot 202 is slidably connected with a clamping post 111, and a third permanent magnet is installed within the clamping post 111. The second permanent magnet 122 close to the electromagnet 22 has opposite magnetic poles to the third permanent magnet. The sliding distance of the adjustment frame 12 is equal to the spacing between the two second permanent magnets 122.

[0052] An elastic member is fixedly connected between the adjustment frame 12 and the limit post 11. In the initial state, the elastic member makes the second permanent magnet 122 close to the electromagnet 22 face the third permanent magnet, and the second permanent magnet 122 forms a magnetic attraction on the third permanent magnet, causing the clamping post 111 to be retracted within the limit post 11 in the initial state; after the adjustment frame 12 is pulled closer to the electromagnet 22, the other second permanent magnet 122 faces the third permanent magnet, and under the action of magnetic repulsion, the clamping post 111 extends out of the limit post 11.

[0053] Refer to Figure 1 , Figures 7 - 9 , it further includes a support mechanism. The support mechanism includes a pressure regulating shell 8 which is fixedly connected to the mounting base 1. A third electric push rod is installed at the bottom inside the pressure regulating shell 8. The output end of the third electric push rod is fixedly connected with a pressure regulating piston 801 which is hermetically and slidably connected within the pressure regulating shell 8. A connecting pipe 7 communicates with the top inside the pressure regulating shell 8. A relief groove 4 is formed within the spacer frame 3. One end of the connecting pipe 7 away from the pressure regulating shell 8 penetrates through the buffer page and communicates with the bottom inside the relief groove 4. A rubber plug 5 is hermetically and slidably connected within the relief groove 4. Multiple springs are fixedly connected to the top of the rubber plug 5, and the top of the springs is fixedly connected with a support post 6. The top end of the support post 6 hermetically penetrates through the spacer frame 3 and abuts against the bottom of the fixed page.

[0054] A pressure sensor is installed at the bottom of the rubber plug 5. The pressure sensor and the third electric push rod are both electrically connected to an external chip, and the external chip receives the signal from the pressure sensor to control the working state of the third electric push rod.

[0055] Refer to Figures 9 - 12, a fourth electric push rod is installed on the pressure regulating shell 8. The output end of the fourth electric push rod is fixedly connected with a rack 16. When the fourth electric push rod works, its output end reciprocates telescopically. A protective shell 17 is fixedly connected to the side of the lubricating shell 9 away from the limiting page. The top end of the rack 16 penetrates into the protective shell 17, and meshes with a linkage gear 161. The linkage gear 161 is rotatably connected in the protective shell 17. A belt linkage assembly 18 is arranged in the protective shell 17. The linkage gear 161 is connected to the input end of the belt linkage assembly 18. Connecting shafts are fixedly connected to both the linkage gear 161 and the output end of the belt linkage assembly 18. One ends of multiple connecting shafts away from the linkage gear 161 all penetrate into the lubricating shell 9 in a sealed manner and are fixedly connected with stirring gears 19. Multiple stirring frames 20 are rotatably connected in the lubricating shell 9. A torsion spring is fixedly connected between the stirring frame 20 and the lubricating shell 9. One ends of multiple stirring frames 20 respectively abut against multiple stirring gears 19, and the other ends abut against the same elastic shell 21. The elastic shell 21 is fixedly connected in the lubricating shell 9.

[0056] The belt linkage assembly 18 adopts the prior art. The linkage gear 161 is linked with its own belt pulley through a belt, and adjacent two belt pulleys are linked through the belt. The belt pulley is coaxially fixed with the connecting shaft. The power of the linkage gear 161 is transmitted to the belt pulley through the belt and finally transmitted to the connecting shaft to complete the transmission function.

[0057] When the present invention is in use, the mounting seat 1 is fixed to one end that is not often disassembled with bolts, and a backing plate frame 3 is padded between the mounting seat 1 and the component to be mounted.

[0058] Control the output end of the first electric push rod to contract, pull the first moving frame 13, so that the replenishing frame 15 is away from the end of the clamping convex block 101. Align the clamping groove 201 of the rotating frame 2 with the clamping convex block 101 and insert it. Then, extend the output end of the first electric push rod, so that the replenishing frame 15 is inserted into the clamping groove 201, facilitating the rotation of the rotating frame 2 on the replenishing frame 15 through the clamping groove 201.

[0059] Control the output end of the second electric push rod in the first moving frame 13 to extend, so that the second moving frame 14 is clamped and connected with the limiting column 11. At this time, when the first electric push rod works, the limiting column 11 can be indirectly controlled to slide inside the limiting tube 10 through the first moving frame 13, the second electric push rod and the second moving frame 14.

[0060] When the output end of the first electric push rod extends, the limiting column 11 also inserts into the limiting groove 202 of the rotating frame 2. The limiting column 11 limits the rotation angle of the rotating frame 2. Only need to control the output end of the first electric push rod to contract, then the replenishing frame 15 and the limiting column 11 can be both away from the rotating frame 2. At this time, only need to rotate the rotating frame 2 to a suitable angle and take it out along the clamping groove 201, then the rotating frame 2 can be quickly disassembled, and it is also convenient for subsequent quick installation.

[0061] The interior of the lubricating shell 9 is filled with liquid lubricating oil. The area of the mounting seat 1 covered by the lubricating shell 9 is exactly the area where the rotating frame 2 rotates. And several arc-shaped lubricating grooves 102 are formed on the side of this area facing the rotating frame 2. Several lubricating holes 103 are communicated between the lubricating grooves 102 and the lubricating shell 9.

[0062] When the rotating frame 2 is in the closed state, the lubricating grooves 102 are in a sealed space due to the sealing effect of the sealing plugs 203 embedded in the inner wall of the rotating frame 2 on the lubricating holes 103. The limiting pages of the mounting seat 1 and the lubricating pages of the rotating frame 2 are in sealed frictional contact. It can be lubricated by the lubricating oil in the lubricating grooves 102 for use when opening and closing, and the excess lubricating oil will not flow out when closed. The entire hinge structure can be installed and used at different angles, and it is difficult for external temperature changes to affect the lubricating groove 102 area in the sealed state.

[0063] When the electromagnet 22 works, the electromagnet 22 is energized to generate a magnetic field externally, magnetically attracting the first permanent magnet 121 on the adjusting frame 12, so that a part of the adjusting frame 12 extends out of the limiting column 11. The positions of the two second permanent magnets 122 inside the adjusting frame 12 change. Since the magnetic poles of the two second permanent magnets 122 are opposite, after the two second permanent magnets 122 move, the second permanent magnet 122 that originally magnetically attracted the third permanent magnet in the clamping column 111 moves away, so that the second permanent magnet 122 that magnetically repels the third permanent magnet is aligned with the clamping column 111. Under the magnetic repulsion of the two, the clamping column 111 extends out of the limiting column 11 and presses against the inner wall of the limiting groove 202 of the rotating frame 2, further restricting the rotating frame 2 to prevent it from moving.

[0064] When it is necessary to increase the damping between the rotating frame 2 and the mounting seat 1, control the output end of the first electric push rod to contract, indirectly control the limiting column 11 to move towards the direction close to the electromagnet 22. The limiting column 11 increases the contact pressure between the lubricating page and the limiting page through the frictional effect of the clamping column 111 on the lubricating page of the rotating frame 2, and increases the resistance at the contact part of the mounting seat 1 and the rotating frame 2 by increasing the pressure. This part of the resistance mainly comes from the compressed sealing plugs 203, so the damage to the mounting seat 1 and the rotating frame 2 is also relatively small.

[0065] During the process of the limiting column 11 approaching the electromagnet 22, the electromagnet 22 still forms a magnetic attraction on the first permanent magnet 121, so that the adjusting frame 12 moves with the movement of the limiting column 11, maintaining the magnetic repulsion effect of the second permanent magnet 122 on the adjusting frame 12 on the third permanent magnet of the clamping column 111.

[0066] In addition, the third electric push rod operates, and its output end drives the pressure regulating piston 801 to move, changing the size of the space between the top of the pressure regulating piston 801 and the inside of the pressure regulating shell 8, changing the internal air pressure, and thus, through the connecting pipe 7, changing the internal air pressure of the relief groove 4. Under the action of the air pressure, the spring is overcome to push the support column 6 upward to abut against the bottom of the fixed page of the rotating frame 2. Then, controlled by an external chip, when the rotating frame 2 rotates, the contact pressure between the support column 6 and the fixed page changes accordingly. Under the elastic force of the spring, the rubber plug 5 moves accordingly, and the pressure sensor 501 detects the pressure change at the bottom of the relief groove 4. The external chip receives the signal from the pressure sensor 501 and controls the operation of the third electric push rod to move the pressure regulating piston 801, ultimately keeping the value of the pressure sensor 501 within a stable range, even if the rotating frame 2 is constantly subjected to the resistance restricting its rotation from the support column 6.

[0067] The lubricating oil in the lubricating shell 9 is also doped with a sufficient amount of nanoscale Fe 3 O 4 particles. The nanoscale Fe 3 O 4 particles are dispersed in the lubricating oil after surface modification to form a ferrofluid. Such particles exhibit superparamagnetism under the action of an external magnetic field, resulting in a significant increase in the viscosity of the lubricating oil and a decrease in fluidity, so that the lubricating oil with increased viscosity cannot pass through the lubricating hole 103, avoiding lubricating oil loss.

[0068] During the continuous closing and unfolding of the rotating frame 2, when the rotating frame 2 rotates away from the mounting seat 1 once, the lubricating hole 103 is no longer sealed by the sealing plug 203 at this time. The electromagnet 22 is controlled to lose its magnetic field when powered off. When the magnetic field is removed, the directional arrangement of the magnetic particles is disrupted, and the lubricating oil restores its original fluidity, facilitating the passage of the lubricating oil through the lubricating hole 103 to lubricate the rotating frame 2 and the mounting seat 1.

[0069] The viscosity change characteristic of the ferrofluid is directly related to the magnetic field strength, and the lubrication effect can be dynamically controlled by adjusting the magnetic field.

[0070] To ensure the uniform distribution of the magnetic particles inside the lubricating shell 9, the fourth electric push rod inside the pressure regulating shell 8 operates, and its output end controls the rack 16 to move up and down. The movement of the rack 16 drives the meshing linkage gear 161 to rotate. The rotation of the linkage gear 161 drives the belt linkage assembly 18 to move, thereby driving multiple stirring gears 19 to rotate. When the stirring gears 19 rotate, under the elastic force of the torsion spring, the stirring frame 20 can be continuously toggled. When the stirring frame 20 rotates, it knocks on the elastic shell 21. The rotation of the stirring gears 19 and the knocking of the stirring frame 20 can make the magnetic particles deposited at the bottom evenly distributed, better play a role under the action of the magnetic field, facilitate controlling the fluidity of the lubricating oil for lubrication according to the working requirements at any time, and avoid excessive loss due to too strong fluidity of the lubricating oil.

[0071] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
