[0002] A hinge is a mechanical device used to connect two solid objects and allow them to rotate relative to each other. It is commonly used in doors, covers, and other parts that require hinged connections.

[0003] Chinese Patent Publication No. CN 113756667 A discloses a Chinese invention patent entitled "An Electric Hinge," which includes: an upper hinge fixed to a door or window frame; a lower hinge fixed to a door or window; a shape memory alloy strip, one end of which is fixedly connected to the upper hinge and the other end to the lower hinge. When the temperature of the shape memory alloy strip changes to its phase transition temperature, the strip deforms according to a pre-set shape, forcing the upper and lower hinges to rotate relative to each other, thereby rotating the door or window; a power source to provide electrical energy to force the shape memory alloy strip to change its temperature; and a power switch to control the power supply to heat or cool the shape memory alloy strip. This electric hinge allows the opening and closing of doors or windows to be controlled remotely, saving time and effort, greatly facilitating people's lives, improving the quality of life, and making home life more intelligent.

[0004] However, when the inventors implemented this device, they found the following defects: the hinge switch driven by heating or cooling the shape memory alloy strip with electrical energy has poor stability and is easily affected by the ambient temperature.

[0052] Example 2

[0053] The novel hinge provided in Example 1 is further optimized, specifically, as follows: Figure 3 As shown, the first mounting part 1 includes a first base 101. The side of the first base 101 facing the second mounting part 2 is provided with a first swing arm seat mounting groove 102. A first swing arm mounting seat is installed inside the first swing arm seat mounting groove 102. The first swing arm mounting seat is hinged to one end of the swing arm part 3.

[0054] The second mounting part 2 includes a second base 201. The side of the second base 201 facing the first base 101 is provided with a second swing arm seat mounting groove 202. A second swing arm mounting seat is provided inside the second swing arm seat mounting groove 202. The second swing arm mounting seat is hinged to the other end of the swing arm part 3.

[0055] Through the above structural design, the first base 101 and the second base 201 are respectively used to fix the two objects to be connected, and can be installed in a pre-embedded manner, serving as a concealed hinge. The first swing arm mounting seat and the second swing arm mounting seat are used to install the swing arm 3, so that the first base 101 and the second base 201 can be connected together and can rotate. Thus, the basic hinge function is realized.

[0056] Specifically, the first swing arm mounting base includes an upper first swing arm mounting base 103 and a lower first swing arm mounting base 104, which are respectively installed at the upper and lower ends inside the first swing arm mounting groove 102. This is used to hinge one end of the swing arm portion 3 from both the upper and lower sides. The second swing arm mounting base includes an upper second swing arm mounting base 203 and a lower second swing arm mounting base 204, which are respectively installed at the upper and lower ends inside the second swing arm mounting groove 202. This is used to hinge the other end of the swing arm portion 3 from both the upper and lower sides.

[0057] It should be noted that the upper 203 and lower 204 of the second swing arm mounting base are connected to the second swing arm mounting groove 202 by bolts. The connecting holes of the second swing arm mounting groove 202, the upper 203 and the lower 204 of the second swing arm mounting base are all runway round holes, and the runway round holes on the upper 203 and the lower 204 of the second swing arm mounting base are distributed in a cross shape with the runway round holes on the second swing arm mounting groove 202.

[0058] Through the above structural design, the installation positions of the upper 103 and lower 104 of the first swing arm mounting seat, as well as the upper 203 and lower 204 of the second swing arm mounting seat, can be adjusted as needed to improve the adaptability of the hinge. Furthermore, the cross-shaped distribution of the runway-shaped holes allows for vertical and horizontal adjustment of the installation positions of the upper 203 and lower 204 of the second swing arm mounting seat.

[0059] Example 3

[0060] The novel hinges provided in the above embodiments are further optimized, such as... Figures 3-5As shown, the swing arm 3 includes a first swing arm 301 and a second swing arm 302. The first swing arm 301 and the second swing arm 302 are respectively hinged to the first swing arm mounting base and the second swing arm mounting base. A third swing arm 303 and a fourth swing arm 304 are provided between the first swing arm 301 and the second swing arm 302, and the third swing arm 303 and the fourth swing arm 304 are hinged to each other on their axes.

[0061] One end of the third swing arm 303 is hinged to the first swing arm 301, and the other end of the third swing arm 303 is hinged to the second swing arm mounting base. One end of the fourth swing arm 304 is hinged to the second swing arm mounting base, and the other end of the fourth swing arm 304 is hinged to the first swing arm mounting base.

[0062] Through the above structural design, all swing arms can be evenly stressed, thus ensuring stability and robustness during support. Furthermore, both ends of the third swing arm 303 and the fourth swing arm 304 are supported, increasing safety. During opening and closing, the third swing arm 303 and the fourth swing arm 304 restrain each other, preventing sudden acceleration.

[0063] Example 4

[0064] The novel hinges provided in embodiments 1, 2, and 3 above are further optimized, such as... Figures 3-5 As shown, the drive unit 4 includes a drive motor 401, which is mounted on the side of the first base 101, and its cable is led out through a cable groove. To improve the accuracy and stability of the drive, the drive motor 401 is preferably a servo motor or a stepper motor. The output end of the drive motor 401 is provided with a power transmission component, which extends into the interior of the first swing arm seat mounting groove 102 to drive the first swing arm 301.

[0065] A mounting bracket 402 is provided at the upper end of the drive motor 401, and a sealing plate 403 is provided on the side of the mounting bracket 402. The sealing plate 403 is bolted to the side of the first swing arm seat mounting groove 102, so that the entire drive unit 4 can be easily disassembled and assembled. The power transmission component is installed above the mounting bracket 402, and the mounting bracket 402 can provide stable support for the power transmission component.

[0066] The power transmission component includes a drive gear 405, a relay gear 406, and a drive gear 407. The drive gear 405 is connected to the output end of the drive motor 401, and the shaft of the drive gear 407 is connected to the first swing arm 301. The relay gear 406 is meshed between the drive gear 405 and the drive gear 407. Using the drive gear 405, relay gear 406, and drive gear 407 to form the power transmission component provides torque output to the first swing arm 301, thus providing a more stable power output during use. It eliminates the need for a reduction gearbox. Furthermore, changing the tooth pitch or diameter between the drive gear 405, relay gear 406, and drive gear 407 can effectively create deceleration or acceleration effects, expanding the hinge's applicability.

[0067] It should be noted that the top of the mounting bracket 402 is provided with a transmission mounting seat 404. The transmission mounting seat 404 includes two clamping plates, and the drive gear 405, the intermediate gear 406 and the driving gear 407 are all installed between the two clamping plates, thereby effectively improving the stability of the connection between the drive gear 405, the intermediate gear 406 and the driving gear 407, and providing a certain degree of protection.

[0068] The novel hinge provided by this utility model is used as follows:

[0069] The first base 101 and the second base 201 are fixed to the mounting surfaces of the two objects with screws. Then, the two ends of the swing arm 3 are respectively installed in the first swing arm mounting seat and the second swing arm mounting seat, and then the first swing arm mounting seat and the second swing arm mounting seat are installed respectively. During the installation process, the first swing arm mounting seat is installed first, so that the drive gear 407 can stably transmit power to the first swing arm 301. The drive motor 401 is then powered on and tested. Then, according to the installation position requirements, the installation positions of the upper 203 and the lower 204 of the second swing arm mounting seat are adjusted to keep the entire hinge stable.
