Description

Technical Field

[0001] This application relates to the field of anti-torsion arms, and more specifically, to a carbon fiber anti-torsion arm. Background Technology

[0002] With increasing demands for lightweighting and structural performance optimization, carbon fiber composites, due to their high specific strength and strong corrosion resistance, are gradually replacing traditional steel and aluminum alloys in torsional structures such as automotive suspensions and industrial equipment supports. Currently, most mainstream carbon fiber torsion arms adopt a single-arm integrated structure. While this meets basic torsional requirements, it suffers from two major drawbacks: Insufficient flexibility in stiffness adjustment: Traditional torsion arms have fixed structural parameters, and torsional stiffness cannot be dynamically adjusted according to operating conditions. For example, in equipment such as carbon fiber torsion beams in automotive suspensions and industrial power arms, the fixed-stiffness torsion arm is prone to response lag or excessive deformation when loads change or operating conditions switch. A contradiction between adaptability and stability: Some torsion structures achieve length compensation through sliding pairs, but these often employ a single sliding point design, lacking coordinated constraint between the two arms. For instance, a certain lifting carbon fiber torsion arm achieves sliding through a sleeve and ball spline, which can resist reverse torque but cannot actively adjust the position of the torsional support point, making it prone to eccentric deformation under complex loads.

[0003] For example, a lifting carbon fiber anti-torsion assistive arm disclosed in Chinese Patent Publication No. CN220637970U includes two fixed ends, a main suspension beam, an anti-torsion extension sleeve, an anti-torsion fixed sleeve, and a floating ball spline; the ball spline and sleeve cooperate to achieve sliding anti-torsion, resisting the reverse torque of the tightening tool. However, the sliding structure relies on the nested cooperation between the sleeve and the ball spline, and does not have the ability to dynamically adjust stiffness. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a carbon fiber anti-torsion arm, which aims to improve the problem that the sliding structure relies on the nested fit of the sleeve and the ball spline and does not have the ability to dynamically adjust the stiffness.

[0005] This application provides a carbon fiber anti-torsion arm, including a first anti-torsion arm and a second anti-torsion arm.

[0006] The length of the first anti-torsion arm is longer than the length of the second anti-torsion arm. A multi-stage cylinder is installed below the mounting end of the first anti-torsion arm. The mounting end of the second anti-torsion arm is connected to the cylinder rod end of the multi-stage cylinder. A connecting member is fixedly connected to the second anti-torsion arm, and the connecting member is slidably connected to the first anti-torsion arm.

[0007] In one specific implementation, a mounting plate is fixedly connected to the lower part of the mounting end of the first anti-torsion arm, and the multi-stage cylinder is slidably connected to the mounting plate.

[0008] In one specific implementation, a slider is fixedly connected to the multi-stage cylinder, and a groove that cooperates with the slider is provided on the mounting plate.

[0009] In one specific implementation, an adjustment member is provided on the side of the mounting plate, and the adjustment member is sequentially screwed through the side wall of the mounting plate and the slider and rotatably connected to the other side of the slide groove.

[0010] In one specific implementation, the adjusting component includes a knob and a threaded rod. The knob is fixedly connected to the threaded rod, and the other end of the threaded rod is sequentially screwed through the side wall of the mounting plate and the slider, and is rotatably connected to the other side wall of the slide groove.

[0011] In one specific implementation, the connector includes a fixing block and a clamping part. The fixing block is fixedly sleeved on the outside of the second anti-torsion arm, and the clamping part is disposed on the fixing block and slidably sleeved on the outside of the first anti-torsion arm.

[0012] In one specific implementation, the clamp part includes an arc-shaped clamp, two arc-shaped clamps are hinged to each other, and the two arc-shaped clamps are slidably sleeved on the outside of the first anti-torsion arm.

[0013] In one specific implementation, one end of the arc-shaped clamp is rotatably connected to a connecting shaft, the connecting shaft being detachably connected to the other arc-shaped clamp.

[0014] Beneficial effects: 1. By cooperating with the first and second anti-torsion arms, the length of the anti-torsion arms can be adjusted in actual production, thus adapting to various production needs; 2. Through multi-stage adjustment of the multi-stage cylinder, the second anti-torsion arm has the ability to dynamically adjust its stiffness and is better controlled by humans, thus improving the accuracy of the second anti-torsion arm when moving.

Detailed Implementation

[0018] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0019] Please see Figures 1-4 This application provides a carbon fiber anti-torsion arm, including a first anti-torsion arm 1 and a second anti-torsion arm 2.

[0020] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The first anti-torsion arm 1 is longer than the second anti-torsion arm 2. Specifically, both the first and second anti-torsion arms 1 and 2 are supported by carbon fiber composite materials, resulting in high strength and corrosion resistance, thus extending their service life. A multi-stage cylinder 3 is installed below the mounting end of the first anti-torsion arm 1. The mounting end of the second anti-torsion arm 2 is connected to the cylinder rod end of the multi-stage cylinder 3. A connecting piece 4 is fixedly connected to the second anti-torsion arm 2, and the connecting piece 4 is slidably connected to the first anti-torsion arm 1. During production, under normal conditions, the first anti-torsion arm 1 operates. When the length of the first anti-torsion arm 1 is short during production, the multi-stage cylinder 3 is activated, causing the cylinder rod end of the multi-stage cylinder 3 to extend, thereby making the extended length of the second anti-torsion arm 2 greater than the length of the first anti-torsion arm 1, thus achieving normal operation. Through the cooperation of the first and second anti-torsion arms 1 and 2, the length of the anti-torsion arms can be adjusted in actual production, thus adapting to various production needs. Through the multi-stage adjustment of the multi-stage cylinder 3, the second anti-torsion arm 2 has the ability to dynamically adjust its stiffness and is better controlled by humans, thereby improving the accuracy of the second anti-torsion arm 2 when it moves.

[0021] In this embodiment, a mounting plate 5 is fixedly connected to the lower part of the mounting end of the first anti-torsion arm 1, and the multi-stage cylinder 3 is slidably connected to the mounting plate 5. A slider 7 is fixedly connected to the multi-stage cylinder 3, and a groove 51 that mates with the slider 7 is provided on the mounting plate 5. An adjusting member 6 is provided on the side of the mounting plate 5, and the adjusting member 6 is sequentially screwed through the side wall of the mounting plate 5 and the slider 7 and rotatably connected to the other side of the groove 51. The adjusting member 6 includes a knob 61 and a threaded rod 62. The knob 61 is fixedly connected to the threaded rod 62, and the other end of the threaded rod 62 is sequentially screwed through the side wall of the mounting plate 5 and the slider 7 and rotatably connected to the other side wall of the groove 51. When it is necessary to adjust the multi-stage cylinder 3, the knob 61 is rotated, causing the threaded rod 62 to rotate, thereby causing the slider 7 to move inside the groove 51, thus changing the position of the multi-stage cylinder 3.

[0022] In this embodiment, the connector 4 includes a fixing block 41 and a clamping part 42. The fixing block 41 is fixedly sleeved on the outside of the second anti-torsion arm 2, and the clamping part 42 is disposed on the fixing block 41 and slidably sleeved on the outside of the first anti-torsion arm 1. The clamping part 42 includes an arc-shaped clamp 421, and two arc-shaped clamps 421 are hinged to each other and slidably sleeved on the outside of the first anti-torsion arm 1 respectively. The other end of one arc-shaped clamp 421 is rotatably connected to a connecting shaft 422, and the connecting shaft 422 is detachably connected to the other arc-shaped clamp 421. The sliding connection between the arc-shaped clamp 421 and the first anti-torsion arm 1 makes the second anti-torsion arm 2 more stable during operation and facilitates disassembly.

[0023] Working principle of the carbon fiber anti-torsion arm: During production, under normal conditions, the first anti-torsion arm 1 operates. When the length of the first anti-torsion arm 1 is short during production, the multi-stage cylinder 3 is activated, causing the cylinder rod end of the multi-stage cylinder 3 to extend. This results in the second anti-torsion arm 2 extending to a length greater than the first anti-torsion arm 1, thus achieving normal operation. Through the cooperation of the first anti-torsion arm 1 and the second anti-torsion arm 2, the length of the anti-torsion arms can be adjusted in actual production, thus adapting to various production needs. The multi-stage adjustment of the multi-stage cylinder 3 enables the second anti-torsion arm 2 to have dynamic stiffness adjustment capability, allowing for better human control and improving the accuracy of its movement.

[0024] It should be noted that the specific model and specifications of the multi-stage cylinder 3 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0025] The power supply and principle of the multi-stage cylinder 3 are clear to those skilled in the art and will not be described in detail here.
