The cup cavity of the hinge cup is closed at the position of the rocker arm and the first linkage part. Since the first linkage part and the second linkage part of the linkage component form an angle design, the rocker arm and the first linkage part can be in a vertical state, reducing the space occupied.

[0039] The following is for reference. Figure 1 and Figure 2 Description of a shallow cup buffer hinge according to an embodiment of the present invention.

[0040] like Figure 1 and Figure 2 As shown, the shallow cup buffer hinge according to an embodiment of the present utility model includes a hinge body 100, a hinge cup 200, a rocker arm 300, and a linkage 400.

[0041] A damping cylinder 500 is provided on the hinge body 100; a hinge cup 200 is located on the front side of the hinge body 100, the hinge cup 200 has a cup cavity 210, and a U-shaped pin 600 is provided on the cup cavity 210; the two ends of the rocker arm 300 are rotatably connected to the front side of the hinge body 100 and one end of the U-shaped pin 600, respectively; the linkage 400 includes a first linkage part 410 and a second linkage part 420, the included angle formed between the first linkage part 410 and the second linkage part 420 is a right angle or an acute angle, a linkage pivot 430 is provided between the first linkage part 410 and the second linkage part 420 and connected to the hinge body 100, the first linkage part 410 is located on the lower side of the rocker arm 300, the end of the first linkage part 410 is rotatably connected to the other end of the U-shaped pin 600, and the damping cylinder 500 locks the end of the second linkage part 420.

[0042] For example, such as Figure 1 and Figure 2 As shown, a damping cylinder 500 is provided on the hinge body 100, meaning the damping cylinder 500 is connected to the hinge body 100. A hinge cup 200 is located at the front of the hinge body 100 and is rotatable on the hinge body 100; specifically, the hinge cup 200 can rotate to switch between an extended state and a retracted state. The hinge cup 200 has a cup cavity 210. (Refer to...) Figure 3A U-shaped pin 600 is provided on the cup cavity 210, and the U-shaped pin 600 is fixedly connected to the hinge cup 200. The two ends of the rocker arm 300 are rotatably connected to the front side of the hinge body 100 and one end of the U-shaped pin 600, respectively; that is, the rocker arm 300 and the hinge cup 200 are connected together through one end of the U-shaped pin 600. The linkage 400 includes a first linkage part 410 and a second linkage part 420, and the included angle formed between the first linkage part 410 and the second linkage part 420 is a right angle or an acute angle; that is, the linkage 400 has an included angle of a right angle or an acute angle. A linkage pivot 430 is provided between the first linkage part 410 and the second linkage part 420 and connects to the hinge body 100; that is, the linkage 400 and the hinge body 100 are connected through the linkage pivot 430. The first linkage part 410 is located on the lower side of the rocker arm 300. The end of the first linkage part 410 is rotatably connected to the other end of the U-shaped pin 600, that is, the linkage 400 and the hinge cup 200 are connected together through the other end of the U-shaped pin 600. The damping cylinder 500 locks the end of the second linkage part 420, so that the damping cylinder 500 can drive the linkage 400 to move.

[0043] In practical work, refer to Figure 4 The hinge cup 200 switches to the unfolded state, which is equivalent to being in the open door state. At this time, the rocker arm 300 and the first linkage part 410 of the linkage component 400 both extend forward. The second linkage part 420 of the linkage component 400 is in a roughly vertical state.

[0044] When it is necessary to close the door, refer to... Figure 4 The hinge cup 200 rotates to switch to the retracted state, equivalent to being in a closed state. During the above process, the hinge cup 200 flips upward around the U-shaped pin 600, the rocker arm 300 flips downward, and the first linkage part 410 of the linkage 400 also flips downward. When the rocker arm 300 and the first linkage part 410 are flipped to a roughly vertical position, the hinge cup 200 is retracted, and the cup cavity 210 of the hinge cup 200 covers the rocker arm 300 and the first linkage part 410. The damping cylinder 500 provides a damping buffer effect for the above process by locking the second linkage part 420 of the linkage 400.

[0045] During the above process, since the cup cavity 210 of the hinge cup 200 covers the rocker arm 300 and the first linkage part 410, the rocker arm 300 and the first linkage part 410 can be in a vertical position, reducing the space occupied. This eliminates the need for a deep inner cavity design for the cup cavity 210, effectively reducing its depth. The hinge cup 200 can then adopt a shallow cup design to match the requirements of thinner door panels.

[0046] In some embodiments of this utility model, reference is made to Figure 3 , Figure 6The linkage 400 has a first linkage hole 411, a second linkage hole 421 and a third linkage hole 431. The first linkage hole 411 is located at the end of the first linkage part 410, the second linkage hole 421 is located at the end of the second linkage part 420, and the third linkage hole 431 is located between the first linkage part 410 and the second linkage part 420. The other end of the U-shaped pin 600 is inserted into the first linkage hole 411. A rear retaining shaft 422 is inserted into the second linkage hole 421. The damping cylinder 500 holds the rear retaining shaft 422. The linkage shaft 430 is inserted into the third linkage hole 431. The linkage 400 can rotate up and down around the linkage shaft 430.

[0047] Reference Figure 4 , Figure 5 A first connecting line 401 is formed between the center of the first linkage hole 411 and the center of the third linkage hole 431, and a second connecting line 402 is formed between the center of the second linkage hole 421 and the center of the third linkage hole 431. An included angle α is formed between the first connecting line 401 and the second connecting line 402, where α is between 80° and 100°. This is equivalent to the linkage component 400 having an included angle formed by the first linkage part 410 and the second linkage part 420.

[0048] The linkage 400 has at least a first linkage hole 411, a second linkage hole 421, and a third linkage hole 431. The first linkage hole 411 connects to a U-shaped pin 600 at the end of the first linkage part 410, and the second linkage hole 421 connects to a retaining pin 422 at the end of the second linkage part 420. The third linkage hole 431 is located at a suitable position between the first linkage part 410 and the second linkage part 420 to fix the linkage shaft 430, thus ensuring the balance of the linkage 400 during rotation and providing support for the linkage 400.

[0049] The first connecting line 401 at the position of the first linkage part 410 and the second connecting line 402 at the position of the second linkage part 420 form an angle α between them, which ranges from 80° to 100°. The shapes of the first linkage part 410 and the second linkage part 420 are slightly adjusted without affecting the first connecting line 401 and the second connecting line 402.

[0050] Reference Figure 5The U-shaped pin 600 on the first linkage hole 411 is linked with the hinge cup 200. The rear retaining pin 422 on the second linkage hole 421 is linked with the damping cylinder 500, ensuring that the damping cylinder 500 can provide stability and damping effect during the movement of the hinge cup 200. Based on this working requirement, the linkage member 400 is designed with an included angle, that is, the linkage member 400 has an included angle formed by the first linkage part 410 and the second linkage part 420. This ensures that the damping cylinder 500 can continuously provide damping effect to the second linkage part 420 of the linkage member 400, while maximizing the retraction of the first linkage part 410 of the linkage member 400. This greatly ensures the overall stability and flexibility of the linkage member, while ensuring that the cup cavity 210 of the hinge cup 200 can adopt a shallow cup design without affecting the retraction of the hinge of this utility model.

[0051] In some specific embodiments of this utility model, both the linkage shaft 430 and the rear locking shaft 422 extend in the left-right direction.

[0052] In some embodiments of this utility model, reference is made to Figure 4 , Figure 5 , Figure 6 A linkage top shaft 412 is provided on the upper side of the first linkage part 410. The rocker arm 300 is connected to the front side of the hinge body 100 via the rocker arm pivot 310. A torsion spring 320 is fitted on the rocker arm pivot 310. One end of the torsion spring 320 presses downward against the linkage top shaft 412, and the other end of the torsion spring 320 presses upward against the lower side of the top wall of the hinge body 100. The torsion spring 320 can apply a downward pushing force to the first linkage part 410. (Refer to...) Figure 4 This allows the torsion spring 320 to provide a continuous thrust to the linkage 400, making it easier to open the door when the hinge of this utility model is switched to the unfolded state.

[0053] In some specific embodiments of this utility model, both the linkage top shaft 412 and the rocker arm rotating shaft 310 extend in the left-right direction.

[0054] In some embodiments of this utility model, reference is made to Figure 6 The first linkage part 410 has an upper protrusion 413 on the upper side and a lower recess 414 on the lower side. This structure makes the stress distribution of the first linkage part 410 more reasonable, and in particular, it can ensure that the first linkage part 410 is not easy to break due to metal fatigue.

[0055] In some embodiments of this utility model, reference is made to Figure 3 , Figure 7A cylinder extension rod 510 is provided on the front side of the damping cylinder 500. A swing member 700 is provided between the cylinder extension rod 510 and the linkage 400. The swing member 700 is connected to the hinge body 100 through a swing member pivot 710 in the middle. The swing member 700 can rotate up and down around the swing member pivot 710. A swing member guide groove 720 is provided on the front side of the swing member 700, and the rear side of the swing member 700 is connected to the cylinder extension rod 510 through a swing member connecting shaft 730. A rear retaining shaft 422 is provided at the end of the second linkage 420, and the rear retaining shaft 422 slides into the swing member guide groove 720. The cylinder extension rod 510 of the damping cylinder 500 is telescopic. The rear retaining shaft 422 can slide within the swing member guide groove 720.

[0056] A swing element 700 is designed at the front end of the cylinder telescopic rod 510 as a mechanical linkage component. The swing element 700 can act as a linkage between the cylinder telescopic rod 510 and the linkage component 400. The middle part of the swing element 700 is firmly connected to the hinge body 100 through the swing element pivot 710, giving the swing element 700 the ability to rotate up and down around the swing element pivot 710. A swing element guide groove 720 is designed on the front part of the swing element 700. This guide groove structure not only guides and restricts the movement trajectory of the swing element 700, but also provides stable support for the rear locking shaft 422 that slides on the swing element 700. On the rear side of the swing element 700, a dedicated swing element connecting shaft 730 is used to achieve a firm and rotatable connection with the cylinder telescopic rod 510, ensuring the reliability and stability of power transmission.

[0057] Through the components and connection methods designed above, during the rotation of the linkage 400, the second linkage part 420 of the linkage 400 can continuously receive the damping buffering effect provided by the damping cylinder 500. Furthermore, since the swing element 700 can be rotated and adjusted, the damping cylinder 500 itself does not need to undergo significant angle adjustments. In this way, the entire hinge mechanism operates efficiently and stably, meeting the usage requirements under complex working conditions.

[0058] In some specific embodiments of this utility model, the connecting shaft 730 of the ornament extends in the left-right direction.

[0059] In some embodiments of this utility model, the guide groove 720 of the ornament is an arc-shaped groove, and the end of the guide groove 720 has a guide groove opening 722. The rear retaining shaft 422 can slide into the guide groove 720 through the guide groove opening 722, which facilitates the assembly and connection of the linkage 400 and the ornament 700.

[0060] In some embodiments of this utility model, the guide groove 720 of the ornament is an arc-shaped groove, and the guide groove 720 of the ornament has an arc-shaped protrusion 721. When the hinge cup 200 is rotated to the unfolded state, the arc-shaped protrusion 721 of the guide groove 720 of the ornament faces downward, ensuring that the process of the linkage 400 driving the ornament 700 to move through the rear retaining shaft 422 is smoother.

[0061] In some embodiments of this utility model, the rear side of the damping cylinder 500 is connected to the hinge body 100 via a cylinder connecting shaft 520, so that the damping cylinder 500 can adjust the angle within a small range to cooperate with the movement of the linkage 400.

[0062] In some embodiments of this utility model, the U-shaped pin 600 has a first connecting pin 610 and a second connecting pin 620 at both ends. The first connecting pin 610 is connected to the rocker arm 300 and the hinge cup 200, and the second connecting pin 620 is connected to the first linkage part 410 and the hinge cup 200, so as to ensure that the hinge cup 200 is sufficiently securely connected to the rocker arm 300 and the linkage part 400.

[0063] In some specific embodiments of this utility model, the first connecting pin 610 and the second connecting pin 620 of the U-shaped pin 600 both extend in the left-right direction.

[0064] In a further embodiment of this utility model, the hinge body 100 has a first side hole 110, a second side hole 120, a third side hole 130, and a fourth side hole 140 on its side wall.
