Description

Technical Field

[0001] This utility model relates to the field of automotive rocker arm technology, and more specifically, to a durable automotive rocker arm. Background Technology

[0002] In existing technologies, the rocker arm of a car has significant design flaws that severely restrict the efficiency and convenience of automotive repair and maintenance. Specifically, the connection between the rocker arm and adjacent mechanical components in current technologies is overly complex and lacks standardized design. This typically makes it difficult to easily connect or disassemble the rocker arm with other parts. Technicians usually need to use various specialized tools, such as special-sized wrenches, sockets, torque wrenches, pry bars, and pullers, to assemble or disassemble the rocker arm. Even more problematic is that in the compact engine compartment or chassis structure of modern cars, the rocker arm is often installed in a space-constrained and poorly oriented location. These confined working environments prevent conventional repair tools from reaching the necessary angles or applying sufficient torque or pulling force. In such situations, even experienced mechanics often face the challenge of not being able to access the necessary tools, hindering convenient assembly and disassembly of the rocker arm. This design flaw... The defects not only significantly extend repair time and increase labor intensity, but also often force technicians to disassemble more adjacent components to obtain sufficient operating space, resulting in a substantial increase in workload and potential additional damage risks. This design feature of difficulty in disassembly and assembly directly leads to reduced automotive repair efficiency and increased costs, making it impossible to conveniently inspect or replace rocker arms. When rocker arms experience wear, deformation, or breakage, the increased difficulty and time cost of repair make timely repairs difficult. This not only extends the vehicle's repair cycle and increases the time and financial burden on car owners, but may also lead to the escalation of the fault due to untimely repairs, further damaging connected steering systems or suspension components, seriously affecting driving safety and driving experience. In addition, this difficulty in disassembly and assembly also limits the implementation of preventive maintenance, making it difficult for technicians to conduct regular inspections and early fault diagnosis, ultimately leading to a series of adverse effects such as shortened service life, increased repair frequency, and decreased overall vehicle reliability.

[0003] (a) Technical problems to be solved

[0004] In view of the problems existing in the prior art, this utility model provides a durable automotive rocker arm to solve the technical problems mentioned in the background art.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a durable automotive rocker arm, comprising a rocker arm, with quick-release levers detachably mounted on both sides of the rocker arm. A quick-release sleeve is detachably fitted onto the outer side of one end of the quick-release lever, and a quick-release groove is formed on the outer side of the quick-release lever. A linkage sleeve is slidably fitted onto the outer side of the quick-release sleeve, and a linkage groove is formed on the inner side of the linkage sleeve. A linkage frame is movably mounted on the inner side of the linkage sleeve. Linkage blocks are fixedly connected to both sides of the linkage frame, and the linkage blocks slide within the linkage groove. A quick-release frame is fixedly connected to one end of the linkage frame, and one end of the quick-release frame is inserted into the quick-release groove. An adapter plate is slidably mounted on one side of the quick-release sleeve, and multiple elastic plates are connected to one side of the adapter plate. An adapter block is fixedly connected to one side of the elastic plate.

[0007] The present invention is further configured such that multiple limiting blocks are fixedly provided on the outer side of the quick-release sleeve, and the setting of the limiting blocks provides space for the adapter block to ensure the coordinated cooperation between the components.

[0008] The present invention is further configured such that a fixing plate is fixedly provided on the outer side of the quick-release sleeve, a push spring is connected to one side of the fixing plate, and the other end of the push spring is connected to the linkage sleeve. The setting of the push spring and the fixing plate realizes the automatic reset function of the linkage sleeve.

[0009] The present invention is further configured such that multiple push springs are provided.

[0010] The present invention is further configured such that the quick-release slot is formed in a ring structure on the outside of the quick-release rod, so that the quick-release slot and the quick-release bracket do not require precise alignment angles, making installation more convenient and faster.

[0011] The present invention is further configured such that the linkage groove is an inclined structure opened on the inner side of the linkage sleeve.

[0012] The present invention is further configured such that a quick-clamp plate is fixedly provided at one end of both the quick-clamp sleeve and the quick-clamp rod, and the elastic plate slides through the quick-clamp plate connected to one end of the quick-clamp sleeve.

[0013] The present invention is further configured such that the outer side of the linkage sleeve adopts a rounded corner structure design and the adapter block adopts an arc-shaped column structure design. This special structural design makes the operation smoother and avoids jamming.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a durable automotive rocker arm with the following advantages:

[0016] 1. The quick-release levers and quick-release sleeves detachably mounted on both sides of the rocker arm enable convenient installation and disassembly without tools. The annular quick-release groove on the outer side of the quick-release lever and the quick-release bracket at the end of the linkage frame form a precise locking mechanism, ensuring accurate connection. The inclined linkage groove on the inner side of the linkage sleeve and the sliding engagement of the linkage block constitute a sensitive force transmission system. This allows the operator to simply pull the linkage sleeve to drive the linkage frame through the linkage block, causing the quick-release bracket to disengage from the quick-release groove and complete the unlocking process. The combination design of the adapter plate and the elastic plate enhances the ease of installation, eliminating the need for separate manual unlocking. The adapter block fixedly connected to one side of the elastic plate ensures a smooth transition between unlocking and locking. This innovative design completely eliminates the complex operation requiring multiple professional tools in traditional rocker arm connections, allowing technicians to easily disassemble and assemble the rocker arm in confined spaces. This significantly improves maintenance efficiency, reduces labor intensity, and solves the problem of difficult disassembly and assembly caused by the inability to reach tools in existing technologies.

[0017] 2. The overall structural design fully considers practicality, durability, and ease of operation. Multiple limiting blocks fixed to the outside of the quick-release sleeve provide precise positional definition for the linkage sleeve, leaving room for the adapter block to prevent excessive movement. The fixing plate on the outside of the quick-release sleeve, combined with the push spring, forms a reliable return mechanism, ensuring the linkage sleeve automatically resets after operation. The multiple push springs enhance the system's stability and durability. The annular structure design of the quick-release slot allows the quick-release bracket to be inserted and locked from any angle, improving installation flexibility. The inclined structure design of the linkage slot further enhances force transmission. This design reduces the force required for operation, and the coordinated work of the overall structure ensures that the rocker arm can be precisely aligned and securely locked during installation, and can be easily unlocked and quickly removed during disassembly. It completely solves the problems of complex, time-consuming, and tool-intensive rocker arm disassembly and assembly in existing technologies, greatly shortening the maintenance cycle, reducing maintenance costs, and avoiding the risk of escalation of failures due to difficult disassembly and assembly. At the same time, it facilitates regular inspections and preventive maintenance by technicians, extends the service life of the rocker arm, improves the overall reliability and safety of the vehicle, and provides users with a more convenient and efficient automotive maintenance experience.

[0027] Please see Figures 1-5 A durable automotive rocker arm includes a rocker arm 1. Both sides of the rocker arm 1 are detachably equipped with quick-locking rods 2. A quick-locking sleeve 3 is detachably fitted onto the outer side of one end of the quick-locking rod 2. A quick-locking groove 4 is formed on the outer side of the quick-locking rod 2. A linkage sleeve 5 is slidably fitted onto the outer side of the quick-locking sleeve 3. A linkage groove 6 is formed on the inner side of the linkage sleeve 5. A linkage frame 7 is movably mounted on the inner side of the linkage sleeve 5. Linkage blocks 8 are fixedly connected to both sides of the linkage frame 7. The linkage blocks 8 slide within the linkage groove 6. A quick-locking bracket 9 is fixedly connected to one end of the linkage frame 7. One end of the quick-locking bracket 9 is inserted into the quick-locking groove 4. An adapter plate 10 is slidably mounted on one side of the quick-locking sleeve 3. Multiple elastic plates 11 are connected to one side of the adapter plate 10. An adapter block 12 is fixedly connected to one side of each elastic plate 11.

[0028] In this embodiment, when the rocker arm 1 needs to be removed, first pull the linkage sleeve 5 to one side. The linkage sleeve 5 will cause the inner inclined linkage groove 6 to slide. Then the linkage block 8 will move in the linkage groove 6, causing the linkage block 8 to drive the linkage frame 7 to slide outward. Then the linkage frame 7 will drive one side of the quick-release bracket 9 to gradually disengage from the quick-release groove 4. During this process, the release sleeve will cooperate with the fixing plate 14 to gradually compress the push spring 15. Due to the rounded corner design of the outer wall of the release sleeve and the arc-shaped column structure of the adapter block 12, the release sleeve will push the adapter block 12 outward. Then the adapter block 12 will drive the elastic plate 11 to tilt outward. When the linkage sleeve 5 has completely moved to the other side of the adapter block 12, the elastic plate 11 will drive the adapter block 12 to return to the center, and one end of the quick-release bracket 9 will completely disengage from the quick-release groove 4. Then the linkage sleeve 5 is connected to the other side of the adapter block 12. Pull the quick-release sleeve 3 outwards to remove it. Then release the linkage sleeve 5. The push spring 15 pushes the linkage sleeve 5 to slide back to its original position. Then the linkage sleeve 5 pushes the adapter block 12 on one side to slide, so that the adapter block 12 drives the elastic plate 11 to slide along the quick-release plate 16 on one side of the quick-release sleeve 3. Then the elastic plate 11 will drive the adapter plate 10 connected at one end to slide back to its original position. When the linkage sleeve 5 is fully reset, one end of the linkage sleeve 5 will abut against the limit block 13. During the reset process of the linkage sleeve 5, the inner linkage groove 6 will slide back to its original position. Then the linkage block 8 will drive the quick-release frame 9 to slide back to its original position through the linkage frame 7. Then pull the quick-release rod 2 out from the other side to the other side to completely remove the quick-release sleeve 3 and quick-release rod 2. Then, follow the above steps to remove the other quick-release sleeves 3 and quick-release rods 2. Then the rocker arm 1 can be removed.

[0029] Please see Figures 3-5 As a further implementation of the overall equipment: multiple limiting blocks 13 are fixedly provided on the outside of the quick-release sleeve 3.

[0030] A fixing plate 14 is fixedly provided on the outside of the quick-release sleeve 3. A push spring 15 is connected to one side of the fixing plate 14, and the other end of the push spring 15 is connected to the linkage sleeve 5.

[0031] Multiple push springs 15 are provided.

[0032] The quick-release slot 4 is a ring-shaped structure located on the outside of the quick-release lever 2.

[0033] The linkage slot 6 is an inclined structure located inside the linkage sleeve 5.

[0034] Both the quick-clamp sleeve 3 and the quick-clamp rod 2 have a quick-clamp plate 16 fixed at one end, and the elastic plate 11 slides through the quick-clamp plate 16 connected to one end of the quick-clamp sleeve 3.

[0035] The outer side of the linkage sleeve 5 adopts a rounded corner structure design, and the adapter block 12 is an arc-shaped column structure design.

[0036] More specifically, when installing the rocker arm 1, first, position the rocker arm 1 correctly and align the mounting holes of the rocker arm 1 and the external component mounting holes concentrically. Then, pass the quick-release rod 2 through the mounting holes from one side, and then fit the quick-release sleeve 3 onto the outside of the quick-release rod 2 from the other side. Next, one side of the adapter plate 10 contacts the mounting surface, preventing it from moving. Then, continue moving the quick-release sleeve 3, causing the elastic plate 11 to slide relative to the adapter block 12. The adapter block 12 then presses against one side of the linkage sleeve 5, causing the linkage sleeve 5 to slide relative to the outside of the quick-release sleeve 3. The linkage sleeve 5 then cooperates with the fixing plate 14 to press against the push spring 15, and simultaneously, the linkage sleeve 5 again drives the inclined inner linkage groove 6 to slide. Then, the linkage block 8 drives the quick-clamp bracket 9 to move outward again through the linkage frame 7. When the quick-clamp sleeve 3 is fully fitted onto the outside of the quick-clamp rod 2, the position of the quick-clamp groove 4 corresponds to the position of the quick-clamp bracket 9, and the pushing force of the push spring 15 is greater than the force applied by the elastic plate 11. Then the push spring 15 pushes the adapter block 12, causing the adapter block 12 to drive the elastic plate 11 to tilt outward again. Then the linkage sleeve 5 will drive the inner linkage groove 6 to slide and reset again, so that the linkage block 8 drives the quick-clamp bracket 9 to slide and reset inward through the linkage frame 7, so that one end of the quick-clamp bracket 9 is inserted into the quick-clamp groove 4. Then the push spring 15 is fully reset, so that one end of the linkage sleeve 5 abuts against the limit block 13, and the elastic plate 11 drives the adapter block 12 to return to the center, realizing the convenient installation of the rocker arm 1.

[0037] In summary, during the use or operation of the overall equipment: when it is necessary to remove the rocker arm 1, first pull the linkage sleeve 5 to one side. The linkage sleeve 5 will cause the inner inclined linkage groove 6 to slide. Then, the linkage block 8 will move in the linkage groove 6, causing the linkage block 8 to drive the linkage frame 7 to slide outward. Then, the linkage frame 7 will drive one side of the quick-lock bracket 9 to gradually disengage from the quick-lock groove 4. During this process, the release sleeve will cooperate with the fixing plate 14 to gradually compress the push spring 15. Due to the rounded corner design of the outer wall of the release sleeve and the arc-shaped column structure of the adapter block 12, the release sleeve will push the adapter block 12 outward. Then, the adapter block 12 will drive the elastic plate 11 to tilt outward. When the linkage sleeve 5 has completely moved to the other side of the adapter block 12, the elastic plate 11 will drive the adapter block 12 to return to the center, and one end of the quick-lock bracket 9 will completely disengage from the quick-lock groove 4. The linkage sleeve 5, together with the quick-clamp sleeve 3, is pulled outward to remove the quick-clamp sleeve 3. Then, the linkage sleeve 5 is released, and the push spring 15 pushes the linkage sleeve 5 to slide back to its original position. Then, the linkage sleeve 5 pushes the adapter block 12 on one side to slide, so that the adapter block 12 drives the elastic plate 11 to slide along the quick-clamp plate 16 on one side of the quick-clamp sleeve 3. Then, the elastic plate 11 will drive the adapter plate 10 connected at one end to slide back to its original position. When the linkage sleeve 5 is completely reset, one end of the linkage sleeve 5 will abut against the limit block 13. During the reset process of the linkage sleeve 5, the inner linkage groove 6 will slide back to its original position. Then, the linkage block 8 will drive the quick-clamp frame 9 to slide back to its original position through the linkage frame 7. Then, the quick-clamp rod 2 is pulled out from the other side to the other side to completely remove the quick-clamp sleeve 3 and the quick-clamp rod 2. Then, the other quick-clamp sleeves 3 and quick-clamp rods 2 are removed by referring to the above steps. Then, the rocker arm 1 can be removed.

[0038] When installing rocker arm 1, first position rocker arm 1 correctly and align the mounting holes of rocker arm 1 and external components concentrically. Then, pass quick-release rod 2 through the mounting holes from one side, and then fit quick-release sleeve 3 onto the outside of quick-release rod 2 from the other side. Next, one side of adapter plate 10 contacts the mounting surface, preventing it from moving. Then, continue moving quick-release sleeve 3, causing elastic plate 11 to slide relative to adapter block 12. Then, adapter block 12 presses against one side of linkage sleeve 5, causing linkage sleeve 5 to slide relative to quick-release sleeve 3. Linkage sleeve 5 then cooperates with fixed plate 14 to press against push spring 15, and simultaneously, linkage sleeve 5 again drives the inclined inner linkage groove 6 to slide. The rear linkage block 8 drives the quick-clamp bracket 9 to move outward again through the linkage frame 7. When the quick-clamp sleeve 3 is fully fitted onto the outside of the quick-clamp rod 2, the position of the quick-clamp groove 4 corresponds to the position of the quick-clamp bracket 9, and the pushing force of the push spring 15 is greater than the force applied by the elastic plate 11. Then the push spring 15 pushes the adapter block 12, causing the adapter block 12 to drive the elastic plate 11 to tilt outward again. Then the linkage sleeve 5 will drive the inner linkage groove 6 to slide and reset again, so that the linkage block 8 drives the quick-clamp bracket 9 to slide and reset inward through the linkage frame 7, so that one end of the quick-clamp bracket 9 is inserted into the quick-clamp groove 4. Then the push spring 15 is fully reset, so that one end of the linkage sleeve 5 abuts against the limit block 13, and the elastic plate 11 drives the adapter block 12 to return to the center, realizing the convenient installation of the rocker arm 1.
