Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a high-strength, low-noise timing belt front cover. Background Technology

[0002] The timing belt cover plays a crucial role in precisely synchronizing the crankshaft and camshaft during the operation of a car engine. The timing belt cover can prevent impurities such as dust, mud, and water from entering the belt's working area, thus avoiding wear, slippage, and other malfunctions caused by these impurities.

[0003] The traditional timing belt cover commonly found on the market has many drawbacks in dealing with engine operation. First, the traditional timing belt cover is mostly a simple protective shell. When the internal fluid of the engine continuously impacts, the cover has to directly bear the impact force of the fluid. Under long-term action, it is very easy to cause excessive local stress on the cover, leading to deformation or even damage, which seriously affects its service life.

[0004] Secondly, traditional timing belt covers cannot effectively convert the impact force when faced with liquid impact. As a result, the impact force of the liquid inside the engine cannot be effectively handled. Under frequent impacts, the stability of the cover is greatly reduced, which not only affects its own structure, but also has an adverse effect on the normal operation of the timing belt and other surrounding components.

[0005] Finally, traditional timing belt front covers cannot effectively convert and store the impact force into elastic potential energy after being hit by liquid. This makes the front cover prone to displacement of components after multiple impacts, further damaging the stability of the overall structure and increasing the probability of failure.

[0006] To address this, a high-strength, low-noise timing belt front cover is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a high-strength, low-noise timing belt front cover to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a high-strength, low-noise timing belt front cover, comprising a timing belt front cover, wherein the interior of the timing belt front cover is provided with a power consumption component for improving the tightness.

[0009] Preferably, the power consumption component includes a columnar groove, which is formed on the top of the timing belt front cover. A sealing cover is slidably connected inside the columnar groove. A return spring is fixedly connected to the top of the inner cavity of the sealing cover. A limit slide rod is fixedly connected to the end of the return spring away from the sealing cover.

[0010] Preferably, the power consumption component further includes a first triangular block, which is fixedly connected to the inner wall of the sealing cover, and a second triangular block is fixedly connected to the inner wall of the sealing cover.

[0011] Preferably, the power consumption component further includes a Z-shaped block, which is slidably connected to the inside of the limiting slide rod. The bottom of the limiting slide rod is fixedly connected to a lever plate, and the lever plate is slidably connected to the inside of the timing belt front cover.

[0012] Preferably, the limiting slide bar is slidably connected to the bottom of the columnar groove, and the Z-shaped block is slidably connected to the inside of the timing belt front cover.

[0013] Preferably, the first triangular block and the second triangular block are arranged in opposite directions.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting up the power consumption components, during the operation of the car engine, the lever plate will convert the power of the internal fluid impact into the power of the limiting slide rod to move the Z-shaped block. At the same time, the Z-shaped block will push the sealing cover into the columnar groove through the first and second triangular blocks, so that the sealing cover and the limiting slide rod will convert the power generated by the lever plate into the power of compressing the return spring, thereby reducing the impact of the internal fluid of the engine on the timing belt front cover and improving the stability of the timing belt front cover.

[0016] Among them, the lever plate can convert the liquid impact force into the power of other components to move, thereby effectively dispersing and transferring the impact force. Because it can disperse the liquid impact force, compared with the traditional timing belt front cover, it bears less instantaneous impact force, reducing the risk of deformation or damage to the timing belt front cover due to excessive local stress, helping to maintain the structural integrity of the timing belt front cover during engine operation and improving stability.

[0017] In addition, the limiting slide bar abuts against the first triangular block and the second triangular block through the Z-shaped block, and finally the sealing cover and the limiting slide bar convert the kinetic energy into the power to compress the return spring. The return spring can effectively convert the power generated by the lever plate into its own elastic potential energy, and at the same time play the role of energy absorption and buffering, improving the stability of the timing belt front cover.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 4 One embodiment of this utility model is a high-strength, low-noise timing belt front cover, including a timing belt front cover 11, the interior of which is provided with a power consumption component for improving the tightness.

[0026] The power consumption component includes a columnar groove 21, which is opened on the top of the timing belt front cover 11. A sealing cover 22 is slidably connected inside the columnar groove 21. A return spring 26 is fixedly connected to the top of the inner cavity of the sealing cover 22. A limit slide rod 25 is fixedly connected to the end of the return spring 26 away from the sealing cover 22.

[0027] The power consumption component also includes a first triangular block 23, which is fixedly connected to the inner wall of the sealing cover 22, and a second triangular block 24 is fixedly connected to the inner wall of the sealing cover 22.

[0028] The power consumption component also includes a Z-shaped block 27, which is slidably connected to the inside of the limiting slide bar 25. The bottom of the limiting slide bar 25 is fixedly connected to a lever plate 28, which is slidably connected to the inside of the timing belt front cover 11.

[0029] The limiting slide bar 25 is slidably connected to the bottom of the columnar groove 21, and the Z-shaped block 27 is slidably connected to the inside of the timing belt front cover 11, so that the limiting slide bar 25 can drive the Z-shaped block 27 to slide inside the timing belt front cover 11.

[0030] The first triangular block 23 and the second triangular block 24 are arranged in opposite directions, so that the Z-shaped block 27 can move the sealing cover 22 by using the first triangular block 23 and the second triangular block 24.

[0031] Working principle: In the initial state, the return spring 26 is not compressed, the Z-shaped block 27 is always in contact with the first triangular block 23 and the second triangular block 24, and the sealing cover 22 is located at the top of the columnar groove 21.

[0032] During operation, when the car engine is running, the engine oil and other liquids inside the engine will continuously impact the lever plate 28 inside the timing belt front cover 11, causing the lever plate 28 to move towards the top of the timing belt front cover 11.

[0033] During this process, the lever plate 28 will drive the limiting slide bar 25 to slide along the timing belt front cover 11 toward the sealing cover 22. Since the limiting slide bar 25 is slidably connected to the bottom of the columnar groove 21 and the Z-shaped block 27 is slidably connected to the inside of the timing belt front cover 11, the limiting slide bar 25 will drive the Z-shaped block 27 to abut against the first triangular block 23 and the second triangular block 24, so that the first triangular block 23 and the second triangular block 24 will drive the sealing cover 22 to slide into the columnar groove 21.

[0034] During the process of the sealing cover 22 sliding into the columnar groove 21, the direction of the movement of the limiting slide rod 25 driven by the lever plate 28 is opposite to the direction of the sliding of the sealing cover 22 into the columnar groove 21. As a result, the limiting slide rod 25 and the sealing cover 22 will compress the return spring 26, thereby converting the force of the liquid impacting the timing belt front cover 11 into the force of compressing the return spring 26.

[0035] Therefore, when the liquid continuously impacts the timing belt front cover 11, the lever plate 28 will always convert the impact force of the liquid into the power to compress the return spring 26, thereby reducing the impact of the liquid inside the engine on the timing belt front cover 11 and improving the stability of the timing belt front cover 11. The lever plate 28 can disperse the liquid impact force, and compared with the traditional timing belt front cover 11, the instantaneous impact force it bears is reduced, reducing the risk of deformation or damage to the timing belt front cover 11 due to excessive local stress. Moreover, the return spring 26 can effectively convert the power generated by the lever plate 28 into its own elastic potential energy, and at the same time play the role of energy absorption and buffering, improving the stability of the timing belt front cover 11.
