Description

Technical Field

[0001] This utility model relates to a household hardware accessory, specifically an external slider hardware buffer hinge. Background Technology

[0002] Buffer hinges, by incorporating damping devices, provide smooth buffering during the opening and closing process, preventing noise and damage caused by excessive impact when the hinge closes. This improves the user experience and extends the product's lifespan. Buffer hinges are widely used in various furniture, electronic products, and household appliances in daily life, becoming an indispensable and important component of modern hardware hinges.

[0003] However, existing buffer hardware hinges still have some shortcomings in design and application, specifically in the following aspects:

[0004] 1. Existing damping hinges typically house the damping device within the hinge cup or arm. However, due to the generally limited internal space of the hinge cup and arm, this design restricts the installation space for the damping device. This confined space necessitates a highly compact design for the damping device to fit within the limited installation area. While this design can achieve a certain degree of damping effect, it increases the manufacturing complexity and cost of the damping device and fails to meet modern demands for efficient damping and long service life.

[0005] 2. Due to the limited internal space of the hinge cup and hinge arm, each component of the damping device needs to be precision-manufactured to ensure proper operation within this confined space. This design not only increases manufacturing difficulty but also raises the defect rate during production, thus affecting product consistency and reliability. The precision manufacturing requirements also lead to increased production costs, and the occurrence of defective products may reduce product durability.

[0006] 3. The limited space in the hinge cup and hinge arm directly restricts the size of the damper, resulting in insufficient cushioning force. Although a small damper can achieve a certain degree of cushioning, its effect is unlikely to reach an ideal level, failing to effectively reduce the impact and noise generated when the hinge closes. This can lead to insufficient cushioning in the hinge over long-term use, affecting the user experience, especially under high-frequency opening and closing conditions.

[0007] 4. Due to the small size of the damper, its internal moving parts experience greater stress, leading to accelerated wear and a gradual decrease in damping effectiveness. Furthermore, the limited internal space may result in poor heat dissipation, restricting the damping device's performance. With temperature changes, the damper's oil may deteriorate, affecting its long-term stability. These factors combined significantly impact the damper's lifespan, necessitating urgent improvements in the design and structure of damping devices to extend their service life and enhance performance. Utility Model Content

[0008] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide an external slider hardware buffer hinge that is simple in structure, easy to use, and effectively improves the buffering effect and extends the service life without increasing manufacturing difficulty and cost.

[0009] The purpose of this utility model is achieved through the following means: an external slider hardware buffer hinge, which includes a hinge cup and a hinge arm. The hinge cup and the hinge arm are hinged together by an upper rocker arm and a lower rocker arm. The upper rocker arm and the lower rocker arm swing relative to the hinge cup and the hinge arm to realize the opening and closing of the hinge. The bottom of the hinge cup is provided with a first clearance groove and a second clearance groove, which are provided through the bottom of the hinge cup body.

[0010] The outer bottom of the hinge cup is also covered with a slider. The slider has a first side plate and a second side plate extending upward on both sides, respectively covering the two outer side walls of the hinge cup.

[0011] The top of the slider is provided with a first guide block and a second guide block, which extend into the first clearance groove and the second clearance groove respectively and slide therein.

[0012] The upper rocker arm is provided with a downwardly extending drive block. When the hinge is closed, the drive block contacts the second guide block and pushes the slider to slide outside the hinge cup.

[0013] A damper is provided between the hinge cup and the slider, and the damper plays a role in damping the movement speed of the slider.

[0014] Furthermore: the first guide block is provided with a first guide groove and a second guide groove through the slider on both sides, and the first clearance groove is provided with a first hook and a second hook extending inward on both sides of the groove. The first hook and the second hook extend into the first guide groove and the second guide groove respectively, and extend into the bottom of the first guide block.

[0015] Furthermore, the cross-section of the second clearance groove is convex, and a guide area is formed between the bottom of the second guide block and the slider. The guide area slides on the side wall of the second clearance groove.

[0016] Furthermore, the end face of the second clearance groove is also provided with a limiting hook extending into the groove. Correspondingly, a positioning area is provided on the second guide block. When the second guide block moves to the end of the second guide groove, the limiting hook extends into the positioning area.

[0017] Furthermore: the outer wall of the hinge cup is recessed inward to form a mounting groove, the second side plate covers the outside of the mounting groove, and the second side plate and the mounting groove together form a mounting area, and the damper is fixed in the mounting area.

[0018] Furthermore, the damper is a compression-damped hydraulic damping cylinder, and the piston rod of the damper is connected to the second side plate.

[0019] Furthermore, the damper has a connecting seat extending rearward from its tail end, and a limiting port is provided on the hinge cup. The other end of the connecting seat extends into the limiting port for fixation, thereby providing axial positioning for the damper.

[0020] Furthermore, the side wall of the hinge cup extends towards the damper with a positioning post, and the tail of the damper is supported on the positioning post, which plays a role in axial positioning of the damper.

[0021] Furthermore: the drive block is disposed on the end face of the upper rocker arm, and the drive block is disposed away from the hinge point between the upper rocker arm and the hinge cup.

[0022] The beneficial effects of this utility model are: 1. Simple structure, low production cost, and improved market competitiveness.

[0023] 2. A key innovation of this invention lies in mounting the buffer on the outside of the hinge arm, thus avoiding the design difficulties of buffer devices caused by limited internal space, a common problem in traditional buffer hardware hinges. Through the ingenious design of the guide groove and drive block, the external mounting method of the buffer not only overcomes the internal space limitations but also makes full use of the space outside the hinge arm, ensuring that the buffer device can be rationally configured and optimized to the greatest extent in terms of function.

[0024] 3. Because the buffer device of this invention is located on the outside of the hinge arm, the internal structure of the hinge cup and hinge arm becomes simpler. The number of internal parts is greatly reduced, decreasing the need for complex mechanical structures and precision manufacturing, thereby improving the stability and reliability of the overall hinge structure. This design not only simplifies the hinge assembly process but also reduces potential manufacturing errors during production, improving the overall quality of the product.

[0025] 4. This utility model, through the design of an external buffer device, not only optimizes the function of the hinge but also reduces the complexity of the internal structure. This significantly reduces the precision requirements for internal parts during production, effectively controlling manufacturing difficulty and cost. The simplified design also makes hinge production more efficient while ensuring high stability and reliability. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to the accompanying drawings. An external slider hardware buffer hinge includes a hinge cup 1 and a hinge arm 2. The hinge cup 1 and the hinge arm 2 are hinged together by an upper rocker arm 3 and a lower rocker arm 4. The upper rocker arm 3 and the lower rocker arm 4 swing relative to the hinge cup 1 and the hinge arm 2 to realize the opening and closing of the hinge. The bottom of the hinge cup 1 is provided with a first clearance groove 11 and a second clearance groove 12, which are provided through the bottom of the hinge cup 1 body.

[0031] The bottom of the hinge cup 1 is also covered by a slider 5. The slider 5 has a first side plate 51 and a second side plate 52 extending upward on both sides, respectively covering the two outer side walls of the hinge cup 1.

[0032] The top of the slider 5 is provided with a first guide block 53 and a second guide block 54, which extend into the first clearance groove 11 and the second clearance groove 12 respectively and slide.

[0033] The upper rocker arm 3 is provided with a downwardly extending drive block 31. When the hinge is closed, the drive block 31 contacts the second guide block 54, pushing the slider 5 to slide outside the hinge cup 1.

[0034] A damper 6 is provided between the hinge cup 1 and the slider 5, and the damper 6 plays a role in damping the movement speed of the slider 5.

[0035] In one embodiment: the first guide block 53 is provided with a first guide groove 55 and a second guide groove 56 that penetrate the slider 5 on both sides; the first clearance groove 11 is provided with a first hook 13 and a second hook 14 extending inward on both sides; the first hook 13 and the second hook 14 extend into the first guide groove 55 and the second guide groove 56 respectively, and extend into the lower part of the first guide block 53.

[0036] In one embodiment: the cross-section of the second clearance groove 12 is convex, and a guide area 57 is formed between the bottom of the second guide block 54 and the slider 5. The guide area 57 slides on the side wall of the second clearance groove 12.

[0037] In one embodiment: the end face of the second clearance groove 12 is also provided with a limiting hook 15 extending inward into the groove. Correspondingly, a positioning area 58 is provided on the second guide block 54. When the second guide block 54 moves to the end of the second guide groove 56, the limiting hook 15 extends into the positioning area 58.

[0038] In one embodiment: the outer wall of the hinge cup 1 is recessed inward to form a mounting groove 16, the second side plate 52 covers the outside of the mounting groove 16, and the second side plate 52 and the mounting groove 16 enclose a mounting area, and the damper 6 is fixed in the mounting area.

[0039] In one embodiment: the damper 6 is a compression damping type hydraulic damping cylinder, and the piston rod 61 of the damper 6 is connected to the second side plate 52.

[0040] like Figure 1-8 As shown, in one embodiment: the rear end of the damper 6 extends to form a connecting seat 62, the hinge cup 1 is provided with a limiting port 17, and the other end of the connecting seat 62 extends into the limiting port 17 for fixation, thereby providing axial positioning for the damper 6.

[0041] like Figure 9 As shown, in one embodiment: the side wall of the hinge cup 1 extends toward the damper 6 with a positioning post 18, and the tail of the damper 6 is supported on the positioning post 18, which plays a role in axial positioning of the damper 6.

[0042] In one embodiment: the drive block 31 is disposed on the end face of the upper rocker arm 3, and the drive block 31 is disposed away from the hinge point between the upper rocker arm 3 and the hinge cup 1.

[0043] Working principle

[0044] In this invention, the hinge cup 1 and hinge arm 2 are hinged together by the upper rocker arm 3 and the lower rocker arm 4, allowing the hinge to move relative to each other during opening and closing. When the hinge cup and hinge arm swing through the rocker arm, the hinge completes the opening and closing action.

[0045] In this case, two clearance grooves are formed at the bottom of the hinge cup, and a first guide block 53 and a second guide block 54 are set at the top of the slider. These two guide blocks extend into the first clearance groove 11 and the second clearance groove 12 respectively, and cooperate with the hooks in the grooves to ensure that the slider can move smoothly on the outer bottom of the hinge cup. At the same time, this connecting structure also serves to connect and position the slider and the hinge cup.

[0046] The upper rocker arm 3 is equipped with a downwardly extending drive block 31. When the hinge closes to a set angle, the drive block 31 contacts the second guide block 54 and pushes the slider 5 to slide outside the hinge cup. At this time, the cooperation between the slider and the damper generates a damping force when the hinge closes, allowing the hinge to close slowly and reducing the impact force when the hinge closes.

[0047] One key technological innovation of this invention is the installation of the damper 6 between the hinge cup 1 and the slider 5, achieving a buffering effect through the movement of the slider. The damper's external location, unrestricted by the internal space of the hinge cup and hinge arm, allows for the use of a larger, more powerful hydraulic damper. This hydraulic damper provides greater damping force, thus more effectively smoothing the hinge's closing action and reducing impact and noise. The piston rod 61 of the damper 6 is connected to the second side plate 52, providing a stronger buffering effect.

[0048] In order to ensure the smooth closing of the hinge, the end face of the second clearance groove 12 is provided with a limiting hook 15 extending into the groove. The limiting hook 15 cooperates with the positioning area 58 on the second guide block 54 to ensure that the relative movement between the guide block and the slider is reasonably limited when the hinge is closed, thereby making the slider movement more stable and smooth, and ensuring the stability of the hinge opening and closing.

[0049] Compared with traditional technologies, this invention solves the problem of difficult buffer design caused by the limited internal space of the hinge cup and hinge arm in traditional designs by placing the buffer device externally. The externally installed buffer can utilize more space, avoiding the constraints of space limitations, and thus providing a more ideal buffering effect.

[0050] By placing the buffer externally, the internal structure of the hinge cup and hinge arm becomes simpler. This reduces the number of complex internal parts, making the overall structure more stable and reliable. The precision requirements for internal components are significantly reduced, thereby decreasing manufacturing difficulty and production costs, while simultaneously improving product consistency and stability.

[0051] In summary, by placing the buffer externally, this invention not only solves the design and manufacturing difficulties caused by limited internal space in existing technologies, but also further enhances the performance and reliability of the hinge by improving the buffering effect and simplifying the internal structure. These innovations give this invention significant technical advantages in improving user experience, extending service life, and reducing production costs.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
