Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a motion cylinder for automotive frames. Background Technology

[0002] Conventional vehicle frames mostly use a sliding friction guiding structure (hydraulic cylinder) to drive the steering motion of the car wheel hub. To reduce the frictional resistance of the hydraulic cylinder, oil is often injected through the oil port, or self-lubricating materials are used to reduce frictional resistance. Due to the high load-bearing capacity of the frame, when the piston rod needs to achieve both extension and rotation, the frictional resistance will increase sharply, leading to problems such as noise during the operation of the frame.

[0003] Therefore, it is necessary to provide a motion cylinder for automobile frames to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a motion cylinder for automobile frames that can withstand the load-bearing capacity of the frame. The piston can perform both telescopic and rotational movements on the cylinder, with low frictional resistance, avoiding noise during the frame's operation and improving the user experience.

[0005] To achieve the above objectives, the technical solution proposed by this utility model is as follows: a motion cylinder for an automobile frame, comprising:

[0006] A cylinder with an opening, wherein an inflation valve is provided on the cylinder, and the cylinder is used for connection to the vehicle frame;

[0007] A guide sleeve, the inner wall of which is provided with a first supporting motion element, is fitted at the opening of the cylinder.

[0008] The piston has a second supporting motion element on its outer wall. The piston is inserted into the cylinder and passes through the guide sleeve. The piston is connected to the car wheel hub and steering cylinder. Gas is injected into the cylinder through the inflation valve to create pressure in the cylinder, causing the piston to extend and move on the cylinder to support the vehicle frame. Alternatively, gas is extracted from the cylinder through the inflation valve to create suction in the cylinder, causing the piston to contract and move on the cylinder to lower the height of the vehicle frame.

[0009] Preferably, the cylinder has a receiving cavity, and the cylinder is provided with a channel communicating with the receiving cavity, and the inflation valve is installed at the channel.

[0010] Preferably, the piston includes a plug head and a piston rod connected to the plug head. The plug head is installed in the receiving cavity of the cylinder, and the piston rod is located in the receiving cavity and extends from the opening of the cylinder to the outside of the cylinder to connect with the vehicle wheel hub and steering cylinder.

[0011] Preferably, the central axes of the plug, piston rod, cylinder, and guide sleeve coincide.

[0012] Preferably, a first mounting groove is formed on the inside of the guide sleeve, the first supporting motion element is housed in the first mounting groove and contacts the outer wall of the piston rod; a second mounting groove is formed on the outer wall of the plug, the second supporting motion element is housed in the second mounting groove and contacts the inner wall of the cylinder.

[0013] Compared with existing technologies, the advantages are that by extracting the gas (nitrogen) from the cylinder through the inflation valve, a suction force is formed inside the cylinder, which causes the piston to contract and move on the cylinder to reduce the height of the frame. In addition, with the cooperation of the first and second support motion elements, the piston can be guided in multiple directions, which makes it convenient for the piston to rotate in the cylinder under the drive of the steering cylinder. Under the load-bearing capacity of the frame, the piston can achieve both telescopic and rotational movements on the cylinder, and the frictional resistance is small, avoiding noise during the operation of the frame, which helps to improve the user experience.

[0014] Other features and advantages of this invention will be set forth in the following description, and in part will be apparent from the description, or may be learned by practice of the invention. The features and advantages of this invention may be realized and obtained by means of the elements and combinations specifically pointed out in the appended claims. Attached Figure Description

[0024] Please see Figures 1 to 3 This utility model provides a motion cylinder for an automobile frame, comprising:

[0025] A cylinder 1 with an opening, wherein an inflation valve 11 is provided on the cylinder 1, and the cylinder 1 is used to connect to the frame 4;

[0026] Guide sleeve 2, the inner wall of which is provided with a first supporting motion element 21, the guide sleeve 2 is installed at the opening of cylinder 1;

[0027] Piston 3, with a second supporting motion element 31 on its outer wall, is inserted into cylinder 1 and passes through guide sleeve 2. Piston 3 is connected to vehicle wheel hub 5 and steering cylinder 6. Gas (nitrogen) is injected into cylinder 1 through inflation valve 11, creating pressure in cylinder 1 and causing piston 3 to extend and support vehicle frame 4. Alternatively, gas (nitrogen) can be extracted from cylinder 1 through inflation valve 11, creating suction in cylinder 1 and causing piston 3 to contract and lower the height of vehicle frame 4. With the cooperation of the first supporting motion element 21 and the second supporting motion element 31, the piston 3 can be guided in multiple directions, allowing piston 3 to rotate in cylinder 1 under the drive of steering cylinder 6.

[0028] It should be noted that in this embodiment, both the first support motion element 21 and the second support motion element 31 are ball bearings. When installed on the guide sleeve 2 and the piston 3, they facilitate the smooth rotation of the piston 3 within the cylinder 1.

[0029] In this way, while bearing the load of the frame 4, the piston 3 can both extend and rotate on the cylinder 1, and the frictional resistance is small, which avoids noise during the operation of the frame 4 and helps to improve the user experience.

[0030] In one specific embodiment, the cylinder 1 has a receiving cavity 10, and the cylinder 1 is provided with a channel 12 communicating with the receiving cavity 10. The inflation valve 11 is installed at the channel 12. The inflation valve 11 is connected to an external air injection pipe, which facilitates the external air injection pipe to inject gas (nitrogen) into the inner cavity of the cylinder 1 through the inflation valve 11, or to extract gas from the cylinder 1.

[0031] In one specific embodiment, the piston 3 includes a plug head 32 and a piston rod 33 connected to the plug head 32. The plug head 32 is installed in the receiving cavity 10 of the cylinder 1, and the piston rod 33 is located in the receiving cavity 10 and extends from the opening of the cylinder 1 to the outside of the cylinder 1, connecting to the wheel hub 5 and the steering cylinder 6. When the external air injection pipe injects gas (nitrogen) into the inner cavity of the cylinder 1 through the air filling valve 11, pressure is generated, causing the piston 3 to move within the receiving cavity 10, and the piston rod 33 extends from the opening of the cylinder 1 to the outside of the cylinder 1. When the external air injection pipe extracts gas from the cylinder 1 through the air filling valve 11, the piston 3 is forced to move within the receiving cavity 10, and the piston rod 33 retracts into the cylinder 1, lowering the height of the frame 4. During this process, the moving cylinder bears the weight of the frame 4, preventing the frame 4 from shaking violently.

[0032] In one specific embodiment, the central axes of the plug head 32, piston rod 33, cylinder 1 and guide sleeve 2 coincide, which facilitates the piston 3 to move axially and retract within the receiving cavity 10 of the cylinder 1.

[0033] In one specific embodiment, a first mounting groove 22 is formed inside the guide sleeve 2, and the first supporting motion element 21 is housed in the first mounting groove 22 and in close contact with the outer wall of the piston rod 33; a second mounting groove is formed on the outer wall of the plug head 32, and the second supporting motion element 31 is housed in the second mounting groove and in close contact with the inner wall of the cylinder 1, which facilitates the smooth rotation of the piston 3 within the cylinder 1. It should be noted that the first mounting groove 22 and the second mounting groove are approximately circular.

[0034] In operation, the gas (nitrogen) inside the cylinder 1 is extracted through the inflation valve 11, creating suction within the cylinder 1. This suction causes the piston 3 to contract and move on the cylinder 1, lowering the height of the frame 4. Furthermore, the combined action of the first and second support elements 21 and 31 provides multi-directional guidance for the piston 3, facilitating its rotation within the cylinder 1 under the influence of the steering cylinder 6. During this process, with the cylinder capable of bearing the load of the frame 4, the piston 3 can achieve both telescopic and rotational movements on the cylinder 1, with low frictional resistance, preventing noise during the frame 4's operation and improving the user experience.

[0035] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
