Description

Technical Field

[0001] This utility model relates to the field of door and window hardware accessories, and in particular to a hinge assembly. Background Technology

[0002] Existing hinges typically include a hinge cup, a base, a damper, and a linkage structure. The linkage structure connects the hinge cup and the base, allowing the hinge cup to move sequentially between an open position, a neutral position, and a closed position relative to the base. The damper is located on the base. When the hinge cup moves from the neutral position to the closed position, one end of the damper abuts against the linkage structure and is compressed to cushion the rotation of the hinge cup relative to the base. Furthermore, to meet the needs of different application scenarios, an adjustment component is usually provided on the base to adjust the damping effect of the damper. However, because the adjustment component occupies a lot of space on the base, it results in a larger overall hinge size and less space on the base for installing other components, making it difficult to improve the performance or structure of the hinge assembly.

When the hinge cup is in the middle position, the elastic member can drive the transmission member to slide. The first connecting rod / second connecting rod is connected to the transmission member. Under the drive of the transmission member, the first connecting rod and the second connecting rod can swing to drive the hinge cup to move to the closed position.

[0012] According to some embodiments of the present invention, the first end of the damper is connected to the transmission member; when the adjusting member is in the first position and the hinge cup moves from the middle position to the closed position, the second end of the damper abuts against the first step, and the first end of the damper moves towards the second end of the damper; when the adjusting member is in the second position and the hinge cup moves from the middle position to the closed position, the second end of the damper abuts against the second step, and the first end of the damper moves towards the second end of the damper.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings.

[0039] Example 1

[0040] Please see Figures 1 to 13This embodiment discloses a hinge assembly, including a hinge cup 1, a base 2, a connecting rod structure 3, an elastic element 4, a damper 5, and an adjusting element 6. The connecting rod structure 3 is hinged to the base 2 and connected to the hinge cup 1. Under the guidance of the connecting rod structure 3, the hinge cup 1 can move relative to the base 2 between an open position, a middle position, and a closed position. The elastic element 4 is disposed between the connecting rod structure 3 and the base 2, and is used to elastically drive the hinge cup 1 to move from the middle position to the closed position. The damper 5 is disposed on the base 2 and can extend and retract along a first direction. The adjusting element 6 is movably disposed on the connecting rod structure 3. The adjusting member 6 is provided with a first step 61 and a second step 62 and can move between a first position and a second position; when the hinge cup 1 is in the open position, in the first direction, the distance between the first step 61 and the damper 5 is greater than the distance between the second step 62 and the damper 5; when the adjusting member 6 is in the first position and the hinge cup 1 moves from the middle position to the closed position, the damper 5 abuts against the first step 61 and is compressed to improve the buffer; when the adjusting member 6 is in the second position and the hinge cup 1 moves from the middle position to the closed position, the damper 5 abuts against the second step 62 and is compressed to provide buffer.

[0041] Specifically, the first direction can be referenced. Figure 4 and Figure 5 In the e1 direction.

[0042] The hinge assembly provided in this embodiment allows users to adjust the contact point between the damper 5 and the adjusting member 6 according to actual needs, thereby adjusting the damping effect. This design increases the product's flexibility and applicability, enabling the same hinge mechanism to meet the needs of different users or different application scenarios. Specifically, moving the adjusting member 6 to the first position reduces the stroke of the damper 5, while moving it to the second position increases the stroke. Users can easily adjust the damping effect by simply sliding the adjusting member 6 to change its relative position with the damper 5. This design avoids complex installation steps and additional tool requirements, making the installation and adjustment process simpler and faster. Importantly, placing the adjusting member 6 on the linkage structure 3 significantly reduces the space occupied on the base 2, making the overall size of the hinge assembly more compact. Furthermore, changing the position of the adjusting member 6 does not affect the damping adjustment function; on the contrary, it increases the available installation space on the base 2, facilitating the installation of other functional components and providing more possibilities for performance improvement and structural innovation of the hinge assembly.

[0043] like Figure 4As shown, preferably, in this embodiment, the adjusting member 6 is slidably disposed on the connecting rod structure 3 along a straight line. After the position of the adjusting member 6 is adjusted, its relative position to the connecting rod structure 3 is fixed so that it rotates synchronously with the connecting rod structure 3. This sliding design of the adjusting member 6 along a straight line allows the user to easily and accurately adjust its position to meet different damping adjustment needs. At the same time, after adjustment, the relative position of the adjusting member 6 and the connecting rod structure 3 is fixed, ensuring the stability and reliability of the hinge assembly during rotation and avoiding the problem of unstable or failed damping effect due to loosening of the adjusting member 6.

[0044] It should be noted that in some other embodiments, the adjusting member 6 may also be rotatably set in the connecting rod structure 3. The choice can be made according to actual needs and is not limited here.

[0045] like Figure 4 , Figure 11 , Figure 12 and Figure 13 As shown, preferably, in this embodiment, the linkage structure 3 is hinged to the base 2 via a hinge shaft, and the adjusting member 6 is also slidably connected to the hinge shaft. The adjusting member 6 can move between a first position and a second position along the axial direction of the hinge shaft. Thus, on the one hand, the sliding connection design between the adjusting member 6 and the hinge shaft allows the user to easily and accurately adjust the position of the adjusting member 6. This adjustment method is not only simple to operate but also ensures the stability and reliability of the adjusting member 6 in different positions, thereby meeting diverse damping adjustment needs. On the other hand, directly sliding the adjusting member 6 to the hinge shaft avoids the problem of the adjusting member 6 occupying extra space in traditional designs. This design makes the overall structure of the hinge assembly more compact, reducing not only volume and weight but also improving flexibility and adaptability during installation, providing more freedom for hinge design. Furthermore, the sliding connection between the adjusting member 6 and the hinge shaft reduces performance degradation caused by loosening or wear of the adjusting member 6. This design not only improves the durability and service life of the hinge assembly but also reduces maintenance and replacement costs due to malfunctions.

[0046] like Figure 4 , Figure 11 , Figure 12 and Figure 13As shown, specifically in this embodiment, the linkage structure 3 includes a first linkage 31 and a second linkage 32, and the hinge shaft includes a first hinge shaft 311 and a second hinge shaft 321 that are parallel to each other; one end of the first linkage 31 is hinged to the hinge cup 1, and the other end is hinged to the base 2 through the first hinge shaft 311; one end of the second linkage 32 is hinged to the hinge cup 1, and the other end is hinged to the base 2 through the second hinge shaft 321; the first linkage 31, the second linkage 32, the hinge cup 1 and the base 2 form a four-bar linkage mechanism; the first hinge shaft 311 is located in front of the second hinge shaft 321 in the extension direction of the damper 5; preferably, the adjusting member 6 is slidably connected to the first hinge shaft 311. Thus, by placing the adjusting component 6 on the first hinge shaft 311, the space between the first hinge shaft 311 and the damper 5 is fully utilized. This design ensures that the adjusting component 6 has sufficient installation space, avoiding installation difficulties caused by space limitations. The ample installation space makes the installation process of the adjusting component 6 smoother, reducing possible interference and conflicts during installation, and improving installation efficiency and accuracy. Furthermore, the fact that the adjusting component 6 is located on the first hinge shaft 311 allows users to easily access and operate the adjusting component 6 without complicated tools or additional operating steps. This design not only improves the convenience of adjustment but also allows users to make quick and precise adjustments as needed, meeting the adjustment requirements of different application scenarios.

[0047] like Figure 5 , Figure 6 , Figure 7 , Figure 11 , Figure 12 and Figure 13 As shown, further, in this embodiment, the base 2 is provided with a pressing member 21, and the hinge assembly also includes a transmission member 7. The transmission member 7 is slidably disposed on the base 2. One end of the elastic member 4 is connected to the transmission member 7, and the other end is abutted against the pressing member 21. The elastic member 4 can extend and retract in the first direction to drive the transmission member 7 to slide in the first direction. When the hinge cup 1 is in the middle position, the elastic member 4 can drive the transmission member 7 to slide. The second connecting rod 32 is connected to the transmission member 7. Under the drive of the transmission member 7, the first connecting rod 31 and the second connecting rod 32 can swing to drive the hinge cup 1 to move to the closed position.

[0048] Understandably, in existing technologies, torsion springs are used to drive the hinge cup 1 to rotate from the middle position to the closed position. The installation of torsion springs is relatively complex and difficult, which makes the overall assembly of the hinge not simple and convenient. In this embodiment, a linearly telescopic elastic element 4 is used to replace the torsion spring. The assembly between the elastic element 4, the transmission element 7, the first link 31 and the second link 32 is simpler, improving the assembly efficiency. Furthermore, the elastic element 4 provides linear elastic force, and compared with the torsion spring that provides rotational elastic force, the elastic element 4 has a longer service life, thereby extending the overall service life of the hinge mechanism.

[0049] like Figure 5 and Figure 11 As shown, preferably, in this embodiment, when the hinge cup 1 is in the open position, the second connecting rod 32 abuts against the transmission member 7 to restrict the sliding of the transmission member 7, and under the action of the elastic member 4, the transmission member 7 pushes against the second connecting rod 32 to hold the second connecting rod 32 in the current position, ensuring the stability of the hinge cup 1 in the open position; as Figure 6 and Figure 12 As shown, when the hinge cup 1 is in the middle position, the second connecting rod 32 rotates to the position that releases the sliding restriction on the transmission member 7. The elastic member 4 can drive the transmission member 7 to slide. The second connecting rod 32 is connected to the transmission member 7. Under the drive of the transmission member 7, the second connecting rod 32 and the first connecting rod 31 can swing to drive the hinge cup 1 to the closed position. For details on the state of the hinge cup 1 in the closed position, please refer to [reference needed]. Figure 7 and Figure 13 .

[0050] like Figure 5 , Figure 6 , Figure 7 , Figure 11 , Figure 12 and Figure 13 As shown, preferably, in this embodiment, the transmission member 7 is provided with a transmission groove 73, and the second connecting rod 32 has an extension arm 322. The extension arm 322 and the second connecting rod 32 move synchronously. When the hinge cup 1 is in the open position, the extension arm 322 abuts against the transmission groove 73 to restrict the sliding of the transmission member 7, and under the action of the elastic member 4, the transmission groove 73 pushes against the extension arm 322 to keep the second connecting rod 32 in the current position. When the hinge cup 1 is in the middle position, the extension arm 322 rotates to the position that releases the sliding restriction on the transmission member 7, and the elastic member 4 can drive the transmission member 7 to slide. The extension arm 322 is connected to the transmission groove 73. Under the drive of the transmission groove 73, the second connecting rod 32 and the first connecting rod 31 can swing to drive the hinge cup 1 to move to the closed position. Thus, when the hinge cup 1 is in the open position, the extension arm 322 can stably abut against the transmission groove 73 to restrict the sliding of the transmission component 7. At the same time, under the action of the elastic element 4, the transmission groove 73 can push against the extension arm 322, thereby ensuring that the hinge cup 1, the second connecting rod 32, and the first connecting rod 31 maintain their current positions when not subjected to external forces. When the hinge cup 1 is in the middle position, the extension arm 322 releases the restriction on the transmission component 7, and the elastic element 4 can drive the transmission component 7 to slide. At this time, the extension arm 322 is connected to the transmission groove 73. Through the driving action of the transmission groove 73, the second connecting rod 32 and the first connecting rod 31 can swing precisely, thereby driving the hinge cup 1 to move to the closed position. This design ensures the efficiency and accuracy of the transmission.

[0051] like Figure 5 , Figure 6 , Figure 7 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, further, in this embodiment, the first end of the damper 5 is connected to the transmission member 7; when the adjusting member 6 is in the first position and the hinge cup 1 moves from the middle position to the closed position, the second end of the damper 5 abuts against the first step 61, and the first end of the damper 5 moves towards the second end of the damper 5; when the adjusting member 6 is in the second position and the hinge cup 1 moves from the middle position to the closed position, the second end of the damper 5 abuts against the second step 62, and the first end of the damper 5 moves towards the second end of the damper 5. Thus, by mounting the elastic element 4 and damper 5 together on the transmission element 7, modular installation of the elastic element 4, damper 5, and transmission element 7 is achieved. Importantly, the modularly installed elastic element 4, damper 5, and transmission element 7 can be installed as a whole onto the base 2. During installation, the elastic element 4 and damper 5 can be installed onto the transmission element 7 first, and then the entire module consisting of the elastic element 4, damper 5, and transmission element 7 can be installed onto the base 2. Only one end of the elastic element 4 needs to abut against the pressing element 21. This feature simplifies and stabilizes the overall assembly process of the hinge mechanism, improving its stability and reliability. This not only increases production efficiency and service life but also facilitates later maintenance and replacement. On the one hand, modular installation greatly simplifies the assembly process. Traditional assembly methods require separate installation of the torsion spring and damper 5, which is not only cumbersome but also increases the risk of errors. Modular design allows the elastic element 4, damper 5, and transmission element 7 to be installed as a whole, greatly reducing assembly steps and time, lowering assembly difficulty, and improving production efficiency. Furthermore, modular design makes the structure of the power components more compact and rational. By integrating the elastic element 4, damper 5, and transmission element 7 into a module, the gaps and connection points between components are reduced, thereby improving the overall compactness and structural rationality. This not only optimizes space utilization but also enhances the synergy between components and improves the efficiency of power transmission.

[0052] like Figure 4 and Figure 8 As shown, preferably, in this embodiment, the first connecting rod 31 is provided with a slide groove 312 extending axially along the first hinge axis 311. The adjusting member 6 is fixedly provided with a button block 63, which is slidably connected to the slide groove 312. The user can apply force to the button block 63 to move the adjusting member 6 between a first position and a second position. In this way, a button block 63 is fixedly installed on the adjusting member 6, and a sliding connection is established between the button block 63 and the slide groove 312, providing precise guidance for the movement of the adjusting member 6. This connection mechanism allows the user to easily control the movement of the adjusting member 6 between the first position and the second position by applying force to the button block 63.

[0053] like Figure 4 , Figure 11 , Figure 12 and Figure 13 As shown, more preferably, in this embodiment, the adjusting member 6 is sleeved on the first hinge shaft 311. Thus, the adjusting member 6 sleeved on the first hinge shaft 311 ensures its stability and accuracy during movement. Since the first hinge shaft 311 serves as the support and rotation center of the entire linkage structure 3, its stability and accuracy are crucial. Sleeving the adjusting member 6 on the first hinge shaft 311 effectively prevents the adjusting member 6 from wobbling or shifting during movement, thereby ensuring the accuracy and consistency of adjustment.

[0054] It should be noted that in some other embodiments, the slide groove 312 can also be provided on the second connecting rod 32, and the adjusting member 6 can be correspondingly slidably provided on the second hinge shaft 321, depending on the actual needs.

[0055] like Figure 14 , Figure 15 As shown, preferably, in this embodiment, the transmission member 7 is provided with a first mounting groove 71, the elastic member 4 is disposed in the first mounting groove 71, and one end of the elastic member 4 is connected to the groove wall of the first mounting groove 71. Thus, on the one hand, the elastic element 4 is cleverly placed in the first mounting groove 71 provided on the transmission component 7. This design not only makes the overall structure more compact and effectively utilizes the limited space, but also avoids possible interference and damage to the elastic element 4 in the external environment. At the same time, the compact structure helps to reduce the overall size of the product, improve space utilization, and meet the needs of modern product design for miniaturization and lightweighting. On the other hand, connecting one end of the elastic element 4 to the groove wall of the first mounting groove 71 not only simplifies the assembly process and improves production efficiency, but also makes the elastic element 4 more stable and less likely to fall off or loosen, thereby ensuring the stability and reliability of the product. Furthermore, the design of the first mounting groove 71 makes the replacement and maintenance of the elastic element 4 more convenient. When the elastic element 4 wears or fails due to long-term use, it can be simply disassembled and replaced with a new elastic element 4 without replacing the entire transmission component 7. In addition, this design also provides convenience for product upgrades and modifications. By replacing the elastic element 4 with one of different performance or size, the performance of the product can be adjusted and optimized.

[0056] like Figure 14 and Figure 16As shown, preferably, in this embodiment, the transmission component 7 is provided with a second mounting groove 72, and the damper 5 is disposed in the second mounting groove 72, with the first end of the damper 5 connected to the groove wall of the second mounting groove 72. Thus, on the one hand, by providing a second mounting groove 72 on the transmission component 7 and cleverly placing the damper 5 within it, a high degree of structural integration is achieved. This design not only effectively utilizes the space on the transmission component 7 and avoids potential interference and damage to the damper 5 in the external environment, but also makes the overall structure more compact and aesthetically pleasing. Simultaneously, the integrated design helps reduce the number of parts, lowers assembly complexity, and improves production efficiency. On the other hand, the first end of the damper 5 being connected to the groove wall of the second mounting groove 72 ensures the stability of the damper 5 on the transmission component 7, making it less likely to detach or loosen, thereby greatly improving the stability and reliability of the product. Furthermore, the design of the second mounting groove 72 allows the damper 5 to... Maintenance and replacement become more convenient. When the damper 5 wears out or fails due to long-term use, it can be simply disassembled and replaced with a new damper 5 without disassembling or replacing the entire transmission component 7. This design not only reduces maintenance costs but also improves the maintainability and service life of the product. Furthermore, due to the more compact structure and reduced material requirements, it helps to further reduce production costs. In addition, the integrated design provides potential for product upgrades and modifications. With the continuous advancement of technology and the expansion of application scenarios, users may need to adjust and optimize the performance of the product according to actual needs. The design of the second mounting slot 72 in this embodiment allows users to easily replace dampers 5 with different performance or size, thereby achieving flexible adjustment of product performance.

[0057] like Figure 14 , Figure 15 and Figure 16 As shown, with this configuration, the first mounting slot 71 and the second mounting slot 72 are used to install the elastic element 4 and the damper 5, respectively. The compact structure helps to reduce the total space required for the power components, making the overall design simpler and more efficient, which is conducive to improving the degree of modularity. Furthermore, the elastic element 4, the damper 5, and the transmission component 7 can be quickly assembled into a complete module, making the assembly process of the power components simpler and faster. In addition, the first mounting slot 71 and the second mounting slot 72 provide independent installation space for the elastic element 4 and the damper 5, reducing mutual interference between them, helping to maintain the stability and consistency of the power components during operation, and improving the overall performance.

[0058] like Figure 14 , Figure 15 and Figure 16As shown, preferably, in this embodiment, the elastic element 4 is a compression spring. Thus, on the one hand, the compression spring has stable elastic characteristics, providing a uniform rebound force when compressed by external force. This characteristic allows the hinge mechanism to maintain a smooth movement trajectory during opening and closing, reducing jamming or abnormal noise caused by uneven elastic force. On the other hand, the shape and size of the compression spring can be customized according to specific needs to adapt to different hinge mechanisms and installation environments. Furthermore, the compression spring is made of high-quality spring steel, possessing high strength and durability. During long-term use, even under frequent compression and release, the compression spring maintains good elastic performance and shape stability, extending the service life of the hinge mechanism. Moreover, the production cost of the compression spring is relatively low, and it is easy to procure and process, making the hinge mechanism using the compression spring as the elastic element 4 more price-competitive and helping to reduce overall costs.

[0059] like Figure 11 and Figure 12 As shown, preferably, in this embodiment, the pressing member 21 is a pin, which is inserted into the base 2. Thus, on the one hand, the pin, as a commonly used fastener, has precise dimensions and shape, ensuring stable insertion into the base 2. This design not only achieves precise positioning between hinge components but also effectively prevents relative movement or misalignment between components, thereby guaranteeing the stability and reliability of the hinge mechanism. On the other hand, the installation process of the pin is relatively simple; typically, it only requires inserting it into a predetermined hole and fixing it. This design makes the assembly and disassembly of the hinge mechanism easier, reducing installation and maintenance costs. While reducing the difficulty of disassembling the pin, it also makes the disassembly of the hinge mechanism relatively convenient, facilitating the maintenance or replacement of parts. On the other hand, the pin is inserted into the base 2, forming a tight fit with the base 2, thereby enhancing the overall structural strength of the hinge mechanism. This design enables the hinge mechanism to withstand greater loads and impacts, improving its durability and service life. Furthermore, compared to other complex pressing parts 21 designs, using a pin as the pressing part 21 not only simplifies the structure but also reduces production costs. This design allows the hinge mechanism to maintain high performance while having a higher cost-effectiveness, helping to enhance the product's market competitiveness.

[0060] Preferably, in this embodiment, the transmission component 7 is made of plastic. Of course, in some other embodiments, the transmission component 7 may also be made of metal, but is not limited to it; the choice can be made according to actual needs, and no single limitation is made here.

[0061] It should be noted that in some other embodiments, the elastic element 4 may also be, but is not limited to, a rubber spring, a polyester spring, a fiberglass spring, a gas spring, or a leaf spring, etc., and can be selected according to actual needs. There is no single limitation here.

[0062] It should be noted that in some other embodiments, the linkage structure 3 can also be a connecting arm. One end of the connecting arm is fixed to the hinge cup 1, and the other end is hinged to the base 2 through the hinge shaft. Under the guidance of the connecting arm, the hinge cup 1 can move relative to the base 2 between the open position, the intermediate position and the closed position; the adjusting member 6 is slidably disposed on the hinge shaft of the connecting arm.

[0063] Example 2

[0064] The main difference between this embodiment and Embodiment 1 is that: when the hinge cup 1 is in the open position, the first connecting rod 31 abuts against the transmission member 7 to restrict the sliding of the transmission member 7, and under the action of the elastic member 4, the transmission member 7 pushes against the first connecting rod 31 to keep the first connecting rod 31 in the current position; when the hinge cup 1 is in the middle position, the first connecting rod 31 rotates to the position that releases the sliding restriction on the transmission member 7, the elastic member 4 can drive the transmission member 7 to slide, the first connecting rod 31 is connected to the transmission member 7, and under the drive of the transmission member 7, the first connecting rod 31 and the second connecting rod 32 can swing to drive the hinge cup 1 to move to the closed position.

[0065] In summary, the hinge assembly disclosed in this utility model can bring at least the following beneficial technical effects:

[0066] 1) By setting the adjustment piece 6 on the connecting rod structure 3, the space occupied in the base 2 is significantly reduced, making the overall volume of the hinge assembly more compact;

[0067] 2) The change in the position of the adjustment component 6 did not affect the realization of the damping adjustment function. On the contrary, it increased the available installation space on the base 2, making it easier to install other functional components and providing more possibilities for the performance improvement and structural innovation of the hinge assembly.

[0068] 3) The sliding design of the adjusting component 6 along the straight direction allows users to easily and accurately adjust its position to meet different damping adjustment needs;

[0069] 4) The adjustment component 6 is directly slidably connected to the hinge shaft, which avoids the problem of the adjustment component 6 occupying extra space in the traditional design. This design makes the overall structure of the hinge assembly more compact, which not only reduces the size and weight, but also improves the flexibility and adaptability in the installation process, and provides more freedom for hinge design.

[0070] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
