Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive one-way valve technology, specifically an automotive one-way valve with a protective mechanism. Background Technology
[0002] A one-way valve in an automobile is a mechanical device mainly used to control the one-way or two-way torque transmission between two meshing components in a transmission system. It is usually installed on components such as drive wheels and guide wheels to ensure that power is transmitted in a specific direction, while blocking power transmission in the opposite direction.
[0003] In existing automotive one-way clutches, the spring assembly is mostly located inside the clutch. Therefore, during use, the spring inside the clutch is subjected to compression and rebound for a long time, which can easily lead to damage. Since the spring is inside the clutch, after the spring is damaged, the clutch usually needs to be disassembled before the spring can be repaired. At the same time, most one-way clutches do not have a protective mechanism to protect the clutch during repair. Therefore, we propose an automotive one-way clutch with a protective mechanism. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides an automotive one-way valve with a protective mechanism. The protective housing effectively protects the internal input and output components, preventing impact damage. An inspection port facilitates maintenance of the internal reset spring, ensuring normal operation of the one-way valve. A buffer assembly, with a locking mechanism, secures the input and output components. Furthermore, the buffer rod, piston block, buffer housing, and buffer spring dampen vibrations in the input and output components. This design solves the problem that in existing automotive one-way valves, the spring assembly is mostly located inside the valve. Therefore, during use, the internal spring is subjected to prolonged compression and rebound, easily leading to spring damage. Since the spring is inside the valve, repairs often require disassembly of the valve, and most one-way valves lack a protective mechanism for maintenance and protection.
[0006] (II) Technical Solution
[0007] To achieve the aforementioned protection of the internal input and output components under the protective casing, thereby preventing impact damage and providing an access port for maintenance of the internal reset spring to maintain normal operation of the one-way valve, a buffer assembly is provided. This assembly, with the help of a clamp, secures the input and output components. Simultaneously, the buffer rod, piston block, buffer shell, and buffer spring work together to dampen vibrations in the input and output components. Therefore, this invention provides the following technical solution: A car one-way valve with a protective mechanism, comprising an input component and an output component, the surfaces of which together include:
[0008] A protective component, the protective component including a protective housing, the inner wall of the protective housing having multiple access ports;
[0009] A buffer assembly includes a bracket, a buffer rod fixedly connected to one side of the bracket, a piston block fixedly connected to one end of the buffer rod, a buffer shell slidably connected to the surface of the piston block, and a buffer spring fixedly connected to one side of the inner wall of the buffer shell and one side of the piston block. By providing this protective assembly, the internal input and output components are easily protected by the protective shell, thus preventing them from being damaged by impact. An inspection port is also provided to facilitate maintenance of the internal reset spring, ensuring the normal operation of the one-way controller. The buffer assembly, with the bracket, easily holds the input and output components in place. Simultaneously, the buffer rod, piston block, buffer shell, and buffer spring facilitate vibration damping when the input and output components vibrate.
[0010] As a preferred technical solution of this utility model, the inner walls of the plurality of card holders are distributed and engaged with the surfaces of the input component and the output component. By setting the card holders, it is convenient to install the input component and the output component, and to hold the input component and the output component in the card holders.
[0011] As a preferred technical solution of this utility model, buffer air holes are provided on the upper sides of both the left and right sides of the buffer spring. By providing buffer air holes, the air in the buffer spring can flow and the air flow speed is slowed down, thereby buffering the movement speed of the piston block and reducing the vibration generated by the input component and the output component.
[0012] As a preferred embodiment of this utility model, the opposite ends of multiple corresponding buffer springs are fixedly connected to a connecting ring. By setting the connecting ring, it is convenient to install all the buffer components inside the connecting ring, thereby supporting the buffer components.
[0013] As a preferred technical solution of this utility model, the protective shell is provided with multiple reset components inside. Each reset component includes a limiting slide rod, and a reset spring is sleeved on the rod wall of the limiting slide rod. By setting the reset components, the reset effect between the input component and the output component is facilitated under the action of the reset spring. This allows the input component and the output component to be quickly reset through the multiple buffer components in the connecting ring. At the same time, the movement of the connecting ring is easily limited under the action of the limiting slide rod.
[0014] As a preferred technical solution of this utility model, the left and right ends of the limiting slide rod are fixedly connected to the left and right sides of the inner wall of the protective shell, respectively. The rod wall of the limiting slide rod is slidably connected to the inner wall of the connecting ring. The two ends of the reset spring are fixedly connected to one side of the connecting ring, respectively. By setting the reset spring, it is convenient to drive the input component and the output component to reset and move.

[0017] 1. This automotive one-way valve, by incorporating protective components, effectively protects the internal input and output components from impact damage through a protective housing. It also features an inspection port for easy access to the internal reset spring, ensuring proper operation of the one-way valve. Furthermore, a buffer component, along with a clamping mechanism, effectively holds the input and output components in place. Simultaneously, the buffer rod, piston block, buffer housing, and buffer spring work together to dampen vibrations in the input and output components.
[0018] 2. This automotive one-way switch, by setting a reset component, facilitates a reset effect between the input and output components under the action of the reset spring. This allows the input and output components to be quickly reset through multiple buffer components in the connecting ring.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0025] Example 1
[0026] Reference Figure 1-4 This is the first embodiment of the present invention, providing a car one-way valve with a protective mechanism, including an input component and an output component. The input component is disposed to the left of the output component, and the surfaces of the input component and the output component together include:
[0027] The protective component includes a protective housing. The left end of the input component and the right end of the output component penetrate through the left and right sides of the inner wall of the protective housing to their respective sides. Multiple inspection ports are provided on the surface of the inner wall of the protective housing.
[0028] The buffer assembly consists of multiple sets, which are evenly distributed inside the protective housing. Each buffer assembly includes a card holder, which is clipped onto the surface of the input and output components. A buffer rod is fixedly connected to one side of the card holder, and a piston block is fixedly connected to one end of the buffer rod. A buffer shell is slidably connected to the surface of the piston block. A buffer spring is fixedly connected to one side of the inner wall of the buffer shell and one side of the piston block. The buffer spring contains air.
[0029] The inner walls of multiple card holders are distributed and engage with the surfaces of the input and output components.
[0030] The upper sides of both sides of the buffer spring are provided with buffer air holes, and rubber sheets are provided inside the buffer air holes. Multiple micropores are provided on the surface of the rubber sheets.
[0031] Multiple corresponding buffer springs are fixedly connected to a connecting ring at opposite ends, and the surface of the connecting ring is slidably connected to the inner wall of the protective shell.
[0032] During use, the device is installed in the location where it is used. When the input and output components are operating, the protective housing helps to protect the input and output components from impact damage. At the same time, the access port facilitates the maintenance of the internal equipment without the need to remove the protective housing.
[0033] When the input and output components operate, they generate power, causing them to vibrate. The buffer rod on the card holder moves within the buffer spring and slides within the buffer spring under the action of the piston block. The piston block can push or draw air out of the buffer spring, and the air in the buffer spring moves slowly through the buffer air hole, thereby slowing down the movement speed of the piston block and buffering the vibration generated by the input and output components. At the same time, under the action of the buffer shell, it is easy to drive the piston block to reset.
[0034] Example 2
[0035] Reference Figure 1-4 In the second embodiment of this utility model, the protective shell is provided with multiple reset components. The reset components include a limiting slide rod, and a reset spring is sleeved on the rod wall of the limiting slide rod.
[0036] The left and right ends of the limiting slide rod are fixedly connected to the left and right sides of the inner wall of the protective shell, respectively. The rod wall of the limiting slide rod is slidably connected to the inner wall of the connecting ring, and the two ends of the return spring are fixedly connected to one side of the connecting ring, respectively.
[0037] During use, when the distance between the input and output components changes, the input and output components move left and right via the buffer rod and buffer spring on the card holder, respectively. The connecting ring slides on the limit slide rod, and the reset spring is stretched due to the change in distance between the two connecting rings. When the reset spring resets, it can drive the connecting ring to reset, thereby driving the buffer spring and the card holder on the buffer rod to reset, and the card holder drives the input and output components to move closer to each other.
[0038] The remaining structure is the same as that in Example 1.
[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
