Description

Technical Field

[0001] This invention relates to the field of automotive manufacturing technology, specifically to a flexible and durable automotive hinge. Background Technology

[0002] A car door hinge is a mechanical device that connects the car door to the car body and allows the door to rotate around an axis. It's essentially the "joint" of the door, a core component that enables the door to open and close. Car door hinges are mainly divided into two categories: stamped concealed hinges and hinged hinges. The former consists of two high-strength steel plates connected by a pivot (pin). One plate is fixed to the A / B / C pillars (body panel), and the other is fixed to the door. The latter is similar in structure to a household door hinge, consisting of multiple sets of hinges connected in series by a long pivot.

[0003] Most existing car hinges are made of steel, which has the advantage of high absolute strength and is not easily deformed. However, with long-term use, their surface will rust, affecting their service life. In addition, after long-term use, the hinge joint will wear out more severely, and the lubrication effect will be relatively poor when lubricating. It is difficult to directly apply the lubricating oil to the hinge joint, which affects the lubrication effect.

[0004] Secondly, existing automotive hinges, in order to balance cost and quality, generally do not use solid structures, but mostly adopt multi-layer sheet metal riveting processes. Sheet metal riveting is generally a press riveting process, while hinge production generally uses a spin riveting process. Therefore, two types of equipment are usually required to work separately. The equipment occupies a large area, has low integration, and affects processing quality and efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a flexible and durable automotive hinge that facilitates lubrication, reduces wear, extends the hinge's service life, and features high integration with processing equipment, thereby improving production efficiency and quality and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flexible and durable automotive hinge, comprising a first hinge seat, a second hinge seat, and a fixing pin. A mounting plate is provided on one side of the first hinge seat, the interior of the second hinge seat is hollow, and a reinforcing rib is installed on the inner wall of the second hinge seat. The first hinge seat and the second hinge seat are hinged by a connecting pin, and a fixing pin is provided between the second hinge seat and the reinforcing rib. One side of the mounting plate is connected to the vehicle beam, and the end of the second hinge seat is connected to the vehicle door. The second hinge seat is L-shaped, and the reinforcing rib and the second hinge seat are triangularly arranged. Fixing pins are set at both ends of the reinforcing rib.

An oil injection hole is provided at the top of the first hinge seat, and the bottom of the oil injection hole is connected to the through hole of the first hinge seat.

[0009] A processing device for flexible and durable automotive hinges, used to process the aforementioned flexible and durable automotive hinge, includes a bottom bracket, a riveting mechanism, a riveting mechanism, a mounting plate, a conveyor rail, and a stepping conveyor assembly mounted on the bottom bracket. The riveting mechanism and the riveting mechanism are arranged side by side. The mounting plate is mounted on the top of the bottom bracket. The conveyor rail is mounted on the outside of the mounting plate. The stepping conveyor assembly is located on one side of the conveyor rail. An end detection mechanism is provided at the tail end of the conveyor rail. The automotive hinge is mounted on the conveyor rail.

[0010] Preferably, the pressing riveting mechanism consists of a hydraulic component and a top pressing plate, and the riveting mechanism consists of a telescopic component, a motor rotating component, and a riveting end head, with the top pressing plate and the riveting end head positioned directly above the conveying track.

[0011] Preferably, the stepping conveyor assembly consists of a first electric push rod, a limiting slide rod, a first sliding plate, a second electric push rod, a slide rail, and a second sliding plate. The first electric push rod and the limiting slide rod are mounted on the top of the mounting plate, the first sliding plate is slidably mounted with the limiting slide rod, the second electric push rod and the slide rail are mounted on the top of the first sliding plate, the second sliding plate slides on the slide rail, the end of the second sliding plate is fixedly connected to one side of the second electric push rod, and the end holder is mounted on the end of the second sliding plate.

[0013] Preferably, a limiting abutment assembly is installed on one side of the mounting plate. The limiting abutment assembly consists of a fixed seat, a limiting electric push rod, and a top block. The fixed seat is installed on the surface of the mounting plate and is located behind the conveying track. The limiting electric push rod is installed on the top of the fixed seat. The top block is connected to the output end of the limiting electric push rod. The bottom of the top block is flush with the top of the conveying track.

[0016] 2. This flexible and durable automotive hinge, through the design of the oil injection hole, improves the lubrication effect by allowing lubricant to be injected into the interior of the rotating connection, unlike traditional hinges where lubricant is generally applied to the outer surface of the rotating connection.

[0017] 3. This flexible and durable automotive hinge, by having the connecting pin and the fixing pin aligned in a straight line during processing, and by employing both a spin riveting mechanism and a press riveting mechanism for separate processing, can improve the integration of processing equipment, reduce the footprint, and improve production efficiency by riveting the fixing pin with the press riveting mechanism, while improving the riveting quality and aesthetics by riveting the connecting pin with the spin riveting mechanism. Combining the two ensures both riveting quality and production efficiency. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 For one embodiment of the present invention, please refer to [link / reference]. Figure 5 , Figure 6 and Figure 8 A flexible and durable automotive hinge includes a first hinge seat 801, a second hinge seat 802, and a fixing pin 806. A mounting plate 803 is provided on one side of the first hinge seat 801. The interior of the second hinge seat 802 is hollow. A reinforcing rib 804 is installed on the inner wall of the second hinge seat 802. The first hinge seat 801 and the second hinge seat 802 are hinged by a connecting pin 805. A fixing pin 806 is provided between the second hinge seat 802 and the reinforcing rib 804. One side of the mounting plate 803 is connected to the vehicle beam, and the end of the second hinge seat 802 is connected to the vehicle door. The second hinge seat 802 is L-shaped, and the reinforcing rib 804 is triangularly arranged with the second hinge seat 802. The fixing pin 806 is set at both ends of the reinforcing rib 804.

[0022] The first hinge seat 801 and the second hinge seat 802 have the same through hole, and a wear-resistant washer 808 is installed inside the through hole.

[0023] Wear-resistant pads 807 are provided at the bottom of the first hinge seat 801 and the top of the second hinge seat 802. The two sets of wear-resistant pads 807 abut against each other. An oil injection hole 809 is provided at the top of the first hinge seat 801. The bottom of the oil injection hole 809 is connected to the through hole of the first hinge seat 801.

[0024] Specifically, existing car hinges on the market are generally made of rigid sheet metal parts riveted together, and the riveting joints are affected by the long-term opening of the car door, resulting in significant wear. In addition, since the door hinges also need to bear the weight of the car door, they will undergo slight deformation during long-term use, greatly reducing their service life. This application designs a flexible and durable automotive hinge. At the rotation point of the connecting pin 805, a wear-resistant washer 808 is provided inside the through hole of the first hinge seat 801 and the second hinge seat 802. This prevents the connecting pin 805 from contacting the inner wall of the through hole of the first hinge seat 801 and the second hinge seat 802. The high wear resistance provided by the wear-resistant washer 808 can significantly reduce the wear caused by the connecting pin 805 on the first hinge seat 801 and the second hinge seat 802 when they rotate relative to each other, thus improving the service life of the automotive hinge. In addition, wear-resistant pads 807 are provided on the contact surfaces of the first hinge seat 801 and the second hinge seat 802 respectively, which also reduces the wear between the contact surfaces of the first hinge seat 801 and the second hinge seat 802.

[0025] In actual production, to ensure a balance between cost and quality, automotive hinges generally use steel structural components, which are often formed by riveting together multiple layers of sheet metal. This improves overall performance and reduces costs. However, in this case, the rigidity of sheet metal components is far less than that of integral castings. When subjected to compression and long-term use, their rigidity decreases significantly. Therefore, this application adds a reinforcing rib 804 inside the second hinge seat 802. The reinforcing rib 804 is made of aluminum alloy. Since aluminum alloy is lightweight, not easily oxidized, and has a lower cost compared to steel sheet metal components, it can significantly improve the overall strength of the automotive hinge without increasing costs excessively.

[0026] In addition, the first hinge seat 801 on the car hinge in this application is provided with an oil injection hole 809 at its top. This design allows lubricating oil to be directly injected into the interior of the first hinge seat 801 and the second hinge seat 802 through the oil injection hole 809 during the lubrication process, thereby improving the lubrication effect.

[0027] Example 2 As one embodiment of the present invention, please refer to Figures 1 to 4 and Figure 7A flexible and durable processing device for automotive hinges, used to process the aforementioned automotive hinges, includes a bottom bracket 1, a riveting mechanism 2 and a riveting mechanism 3 mounted on the bottom bracket 1, a mounting plate 4, a conveying track 5, and a stepping conveying assembly 6. The riveting mechanism 2 and the riveting mechanism 3 are arranged side by side. The mounting plate 4 is mounted on the top of the bottom bracket 1. The conveying track 5 is mounted on the outside of the mounting plate 4. The stepping conveying assembly 6 is located on one side of the conveying track 5. An end detection mechanism 9 is provided at the tail of the conveying track 5. The automotive hinge is mounted on the conveying track 5.

[0028] The top of the conveying track 5 is provided with a top limiting groove 501. The bottom of the connecting pin 805 slides inside the top limiting groove 501. The mounting plate 803 is snapped onto the outside of the conveying track 5. The bottom of the fixing pin 806 slides inside the top limiting groove 501. The fixing pin 806 and the connecting pin 805 are set in the same straight line on the conveying track 5.

[0029] Specifically, during riveting, the car hinges need to be spliced ​​together. First, the reinforcing rib 804 is inserted into the second hinge seat 802. Then, a fixing pin 806 and a connecting pin 805 are inserted into the second hinge seat 802. Next, the first hinge seat 801 is inserted into the bottom of the connecting pin 805. Finally, the spliced ​​car hinge is placed on the conveyor rail 5, with the large ends of the connecting pin 805 and the fixing pin 806 facing down, and placed into the top limiting groove 501 of the conveyor rail 5. The mounting plate 803 is snapped onto the outside of the conveyor rail 5 to limit the first hinge seat 801 and the second hinge seat 802, allowing the car hinge to move laterally as a whole without falling apart. This design of the conveyor rail 5 facilitates stable conveying of the car hinges and improves automation.

[0030] The infeed conveying assembly 6 consists of a first electric push rod 601, a limiting slide rod 602, a first sliding plate 603, a second electric push rod 604, a slide rail 605, and a second sliding plate 606. The first electric push rod 601 and the limiting slide rod 602 are mounted on the top of the mounting plate 4. The first sliding plate 603 is slidably disposed with the limiting slide rod 602. The second electric push rod 604 and the slide rail 605 are mounted on the top of the first sliding plate 603. The second sliding plate 606 slides on the slide rail 605. The end of the second sliding plate 606 is fixedly connected to one side of the second electric push rod 604. The end holder 607 is mounted on the end of the second sliding plate 606.

[0031] Specifically, when the car hinge is conveyed on the conveying track 5, the first electric push rod 601 drives the first sliding plate 603 to move laterally, while the second electric push rod 604 drives the second sliding plate 606 to move vertically. This causes the end holder 607 connected to the end of the second sliding plate 606 to move in a stepping motion on the conveying track 5, which can stepwise convey the car hinge to the area below the riveting mechanism 2 and the riveting mechanism 3, making it convenient to rivet the connecting pin 805 and the fixing pin 806.

[0032] A limiting abutment component 7 is installed on one side of the mounting plate 4. The limiting abutment component 7 consists of a fixed base 701, a limiting electric push rod 702, and a top block 703. The fixed base 701 is installed on the surface of the mounting plate 4 and is located behind the conveying track 5. The limiting electric push rod 702 is installed on the top of the fixed base 701. The top block 703 is connected to the output end of the limiting electric push rod 702. The bottom of the top block 703 is flush with the top of the conveying track 5.

[0033] The riveting mechanism 2 consists of a hydraulic component and a top pressure plate 201, and the riveting mechanism 3 consists of a telescopic component, a motor rotation component, and a riveting end 301. The top pressure plate 201 and the riveting end 301 are positioned directly above the conveying track 5.

[0034] Since the connecting pin 805 and the fixing pin 806 have different functions, the fixing pin 806 is mainly used to strengthen the structural rigidity of the second hinge seat 802. It is in a fixed state and does not rub against other parts, so it is riveted. During riveting, the fixing pin 806 is riveted first. Then, the car hinge is transported to the bottom of the riveting mechanism 2 by the stepping conveyor assembly 6. The limit electric push rod 702 drives the top block 703 to move, so that the top block 703 abuts against one side of the reinforcing rib 804. In addition, the end card seat 607 abuts against the outside of the second hinge seat 802, which can completely fix the second hinge seat 802 and prevent shaking during riveting, thereby reducing the riveting quality. The riveting mechanism 2 presses down the top pressure plate 201, so that the two bottom pressure blocks at the bottom of the top pressure plate 201 simultaneously rivet the two fixing pins 806. The riveting speed is fast and multiple pins can be riveted at the same time, thereby improving production efficiency.

[0035] Since the connecting pin 805 is subjected to the rotation of the first hinge seat 801 and the second hinge seat 802, a riveting process is generally adopted. During riveting, the riveting mechanism 3 drives the riveting end 301 to press down on the top of the connecting pin 805 and rotate it at the same time, so that it rivets the top of the first hinge seat 801.

[0036] This process combines press riveting and spin riveting, allowing them to work simultaneously without interfering with each other. This improves the integration of the riveting process and significantly enhances the production efficiency and quality of automotive hinges.

[0037] An end detection mechanism 9 is provided on one side of the tail end of the conveying track 5. The end detection mechanism 9 is provided with a vertical detection end, which is located directly above the top limiting groove 501.

[0038] After riveting is completed, the height of the connecting pin 805 at the riveting point is detected by the end detection mechanism 9. If it meets the specified parameters, it can be rejected; otherwise, an alarm will be triggered.

[0039] In summary, the flexible and durable automotive hinge designed in this application has high structural strength, good wear resistance, and is easy to lubricate, thus improving lubrication. The processing device for the automotive hinge designed in this application can be applied not only to the automotive hinge of this application but also to commonly used automotive hinges. It has a high degree of integration, a small footprint, and can improve processing efficiency and quality.
