Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of shock absorption and buffer devices, and in particular to a novel damping oil pipe and damper. Background Technology
[0002] A damper is a device that can absorb and dissipate vibration energy, reduce vibration amplitude and frequency. A damper can absorb the impact force of a hinge during movement and reduce the vibration amplitude, thereby achieving a shock absorption effect. This shock absorption effect is crucial for protecting hinges and connecting parts from damage. Especially under frequent opening and closing or heavy load conditions, it can effectively extend the service life of the hinge and adjust the movement speed of the hinge to ensure that the door panel or cover closes more smoothly, avoiding noise and collisions caused by rapid closing.
[0003] However, common dampers on the market require the door panel to be opened more than 30 degrees to trigger the buffer, while small-angle dampers can be triggered at around 10-15 degrees. They have a good buffering effect, but the speed needs to be slowed down and the closing speed needs to be uniform, which makes the overall closing speed slower and cannot provide sufficient flexibility and adaptability. Therefore, further improvements to the existing technology are needed. Utility Model Content
[0004] The purpose of this invention is to provide a novel damping oil pipe designed to solve at least one technical problem in the background art.
[0005] The purpose of this invention is to provide a damper designed to solve at least one technical problem in the background art.
[0006] To achieve the above objectives, the present invention adopts the following solution: a novel damping oil pipe, comprising an oil pipe body, wherein the top of the oil pipe body is provided with an opening and the oil pipe body has an inwardly recessed cavity, the cavity is filled with oil, and the upper and / or middle part of the inner sidewall of the oil pipe body is provided with an oil passage groove for oil flow, the upper and / or middle part of the cavity forms a first hydraulic space, and the lower part of the cavity forms a second hydraulic space.
[0007] The inner wall of the oil pipe body is provided with an inwardly protruding part.
[0008] The protrusion is located in the middle and / or lower part of the inner wall of the tubing body.
[0009] The oil groove is recessed from the top of the protrusion to the bottom of the protrusion.
[0010] The oil passage groove has one or more sets, and the multiple sets of oil passage grooves are arranged at intervals.
[0011] The protrusion has an inclined surface that gradually slopes from the top of the protrusion to the bottom of the protrusion.
[0012] The damper includes a piston and the novel damping oil pipe, wherein the piston is at least partially slidably mounted within the cavity, and its speed is reduced when the piston moves from the first hydraulic space into the second hydraulic space.
[0013] The piston component includes a movable rod and a plug body, the plug body being assembled on the movable rod and at least partially placed within the cavity.
[0014] The outer wall of the plug body is provided with a flow port for oil flow.

[0016] The advantages of this utility model are as follows: This application is provided with an oil groove. When the piston is pushed inward into the first hydraulic space, the oil groove allows the oil to flow, which increases the speed at which the piston is pushed in and prevents it from stopping due to resistance. When the piston is pushed inward into the second hydraulic space, the speed at which the piston is pushed in slows down. Thus, the piston is pushed in at a fast speed in the first part and at a slow speed in the second part, which improves the closing speed. Attached Figure Description

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so as to intuitively and vividly understand each technical feature and overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

When a feature is referred to as "set," "fixed," or "connected" to another feature, it can be directly set, fixed, or connected to the other feature, or it can be indirectly set, fixed, or connected to the other feature.
[0026] In the description of this utility model, the term "several" means one or more, and "multiple" means two or more. The terms "greater than," "less than," and "exceeding" should be understood as excluding the stated number. The terms "above," "below," and "within" should be understood as including the stated number. The terms "first" and "second" should be understood as distinguishing technical features and not as indicating or implying relative importance, the quantity of indicated technical features, or the sequential relationship between indicated technical features.
[0027] Furthermore, unless otherwise defined, the technical and scientific terms used in this invention have the same meanings as commonly understood by one of ordinary skill in the art. The terminology used in this invention is for the purpose of describing particular embodiments only and not for limiting the invention. It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or collections thereof.
[0028] Example 1: As Figure 1-7As shown, a novel damping oil pipe includes an oil pipe body 1. The top of the oil pipe body 1 has an opening 10, and the oil pipe body 1 has an inwardly recessed cavity 100 filled with oil. An oil passage groove 11 for oil flow is provided on the upper and / or middle part of the inner wall of the oil pipe body. A first hydraulic space 101 is formed in the upper and / or middle part of the cavity 100, and a second hydraulic space 102 is formed in the lower part of the cavity. The inner... The side wall is provided with an inwardly protruding protrusion 12, which is located in the middle and / or lower part of the inner side wall of the oil pipe body 1. This application provides an oil groove. When the piston is pushed inward into the first hydraulic space, the oil in the oil groove makes the piston push faster, so that the piston stops without resistance. When the piston is pushed inward into the second hydraulic space, the piston pushes slower. Thus, the piston pushes in faster at the beginning and slower at the end, which improves the closing speed.
[0029] The oil groove 11 is recessed from the top of the protrusion 12 to the bottom of the protrusion 12, so that when the piston is pushed into the oil groove, the oil in the oil groove can lubricate the piston, thereby accelerating the piston's push-in.
[0030] The oil passage 11 has one or more sets, and the multiple sets of oil passage 11 are arranged at intervals. The multiple sets of oil passage 11 enable the piston to be pushed in more quickly.
[0031] The protrusion 12 has an inclined surface 121 that gradually slopes from the top of the protrusion 12 to the bottom of the protrusion 12. The inclined surface reduces the jamming when the piston pushes into the protrusion.
[0032] Example 2: As Figure 1-7 As shown, the damper includes a piston 2 and the novel damping oil pipe. The piston 2 is at least partially slidably mounted in the cavity 10. The piston 2 enters the third hydraulic space, the first hydraulic space, and the second hydraulic space sequentially from the opening. When the piston 2 enters the second hydraulic space from the first hydraulic space, its speed decreases. This application provides an oil groove. When the piston is pushed inward into the first hydraulic space, the oil groove allows the oil to flow, making the piston push faster and preventing it from stopping due to resistance. When the piston is pushed inward into the second hydraulic space, its pushing speed decreases. Thus, the piston pushes in at a fast initial speed and at a slow final speed. When the damper is used on a hinge, the hinge closes at a fast initial speed and at a slow final speed, reducing the noise of the door closing. The slower the final speed, the better the buffering effect, improving the overall door closing speed and enhancing the user experience.
[0033] The piston component 2 includes a movable rod 21 and a plug body 22. The plug body 22 is mounted on the movable rod 21 and is at least partially placed inside the cavity 10. The movable rod is configured to push the plug body.
[0034] The outer wall of the plug body 22 is provided with a flow port 220 for oil flow. The flow port allows some oil to be discharged through the flow port, thereby controlling the flow rate of the oil and slowing down the speed at which the piston is pushed in.
[0035] The piston component 2 includes a seal 23, which is mounted on the movable rod 21 and located above the plug body 22. The seal 23 is at least partially placed in the cavity 10. The seal plays a role in maintaining the damping effect in the hydraulic damper, ensuring that the oil flows along a predetermined path, thereby providing a stable damping force.
[0036] The device includes a first elastic member 3, which is assembled inside the cavity 10. One end of the first elastic member 3 abuts against the inner bottom wall of the cavity 10, and the other end of the first elastic member 3 abuts against the piston member 2. The first elastic member is configured to push the piston member to reset when it is reset.
[0037] and / or
[0038] It includes a second elastic element 4 and a sealing gasket 5. The second elastic element 4 is fitted onto the movable rod 21, and the sealing gasket 5 is fitted onto the movable rod 21 and located above the second elastic element 4. One end of the second elastic element 4 abuts against the sealing gasket 5. The sealing gasket is provided to prevent the second elastic element from coming off the movable rod. The second elastic element is provided so that the damper has a buffering effect when the external force pushes the piston and when the external force is removed from the piston.
[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
