Description

Technical Field

[0001] This invention belongs to the field of vehicle accessories technology, and more specifically, relates to a handrail synchronous adjuster. Background Technology

[0002] There are many types of in-vehicle accessories, ranging from electronic device brackets and charging modules to storage boxes and aromatherapy products. Their design goal is to optimize the user experience within the limited interior space. Among them, the center armrest box, as a core interior component that integrates elbow support and storage functions, directly affects the convenience of daily use due to its internal volume utilization rate. The double-opening design eliminates the need for a central partition or offset hinge pillar, and the internal cavity is a through rectangle, allowing items to be placed vertically, resulting in a high loading rate in cars.

[0003] Currently, in order to improve user comfort and premium feel, some armrest boxes have added noise reduction features. However, the hinge pillars of some armrest boxes are driven by torsion springs. The different torques of the torsion springs on the left and right sides, as well as errors during installation, can easily lead to different opening speeds of the armrest covers on both sides, affecting the premium feel and user experience.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a handrail synchronous adjuster in order to achieve a more practical purpose. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an armrest synchronization adjuster to resolve the issue of inconsistent armrest cover opening speeds affecting the premium feel and user experience.

[0006] The purpose and effect of the handrail synchronization adjuster of the present invention are achieved by the following specific technical means: A handrail synchronization adjuster includes a handrail frame, with two cover plates hinged to the top of the handrail frame. A pivot is provided on the cover plate and passes through the handrail frame. A torsion spring is provided on the handrail frame, with one end of the torsion spring connected to the cover plate and the other end abutting against an adjusting member. The adjusting member's adjusting pivot is subjected to the torsion force of the torsion spring.

[0007] Furthermore, the adjusting component includes an adjusting ring sleeve, and a mounting post is provided at the end of the handrail frame. The adjusting ring sleeve is sleeved on the mounting post. The adjusting ring sleeve includes a ring sleeve body and a coaxial cam. One end of the torsion spring abuts against the cam. A rotation locking mechanism is provided on the adjusting ring sleeve.

[0008] Furthermore, the rotary locking mechanism includes a mounting plate fixedly disposed at the outer end of the mounting column. The mounting plate includes a plate body, with first limiting teeth distributed on the inner circumference of the plate body and second limiting teeth distributed on the inner circumference of the ring body. A return spring sleeved on the mounting column is provided between the handrail frame and the cam. The return spring pushes the cam so that the second limiting teeth in the ring body are engaged between the teeth of the first limiting teeth.

[0009] Furthermore, the disc body has a circumferential protrusion with a limiting protrusion, and the ring body has a limiting strip located on the moving path of the limiting protrusion.

[0010] Furthermore, a retaining sleeve is provided inside the disc body, the retaining sleeve is engaged with the mounting post, and the disc body is connected to the mounting post by bolts.

[0011] Furthermore, the glove extends outward from the periphery of the ring body.

[0012] Furthermore, the end of the handrail frame is provided with a movable groove corresponding to the cover plate, and one end of the torsion spring passes through the movable groove and is engaged with the cover plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: By setting one end of the torsion spring to abut against the adjustment component, the initial torque of the torsion spring can be adjusted, thereby changing the initial torque of the torsion spring. The adjustable setting of the torsion springs on both sides can keep the opening speed of the two covers closer in actual use, achieving basic synchronization and improving the user experience.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] Example: As attached Figure 1 To be continued Figure 7 As shown: This invention provides a handrail synchronization adjuster, including a handrail frame 1. Two cover plates 2, respectively hinged to both sides, are provided on the top of the handrail frame 1. A rotating shaft 6, passing through the handrail frame 1, is provided on each cover plate 2. The handrail frame 1... Figure 8As shown, the flip-up parts at both ends are mounting plates, and the whole is frame-shaped. The rotating shaft 6 on the cover plate 2 passes through the mounting plates at both ends of the handrail frame 1, and the end of the handrail frame 1 has a protruding bushing 102. The rotating shaft 6 is rotated and locked in the bushing 102. A torsion spring 503 is provided on the handrail frame 1. One end of the torsion spring 503 is connected to the cover plate 2, and the other end abuts against the adjusting member 5. The torsion spring 503 is sleeved on the bushing 102.

[0027] An end plate 3 is provided at the end of the handrail frame 1. A limit button 4 is connected to the end plate 3 by a spring. When the button 4 is pressed down, the restriction on the cover plate 2 is released, and the torsion spring 503 drives the cover plate 2 to flip open. The adjusting component 5 determines the initial torque of the torsion spring 503 and the speed at which the cover plate 2 flips.

[0028] In this embodiment, as Figures 3 to 6 As shown, the adjusting component 5 includes an adjusting ring 502. The end of the handrail frame 1 is provided with a mounting post 101. The adjusting ring 502 is sleeved on the mounting post 101. The adjusting ring 502 includes a ring body 5021 and a coaxial cam 5022. Both the ring body 5021 and the cam 5022 are hollowly sleeved on the mounting post 101. One end of the torsion spring 503 abuts against the cam 5022. The rotation of the cam 5022 can push the end of the torsion spring 503 and change the initial torque of the torsion spring 503.

[0029] The adjusting ring 502 is equipped with a rotation locking mechanism, including a mounting plate 501 fixedly mounted on the outer end of the mounting post 101. The mounting plate 501 includes a plate body 5011, with first limiting teeth 5014 distributed on the inner circumference of the plate body 5011, and second limiting teeth 5024 distributed on the inner circumference of the ring body 5021. A return spring 504 sleeved on the mounting post 101 is provided between the handrail frame 1 and the cam 5022. The return spring 504 pushes the cam 5022 so that the second limiting teeth 5024 in the ring body 5021 are engaged between the teeth of the first limiting teeth 5014. Both tooth 5014 and the second limiting tooth 5024 are triangular teeth. By forcefully rotating the ring body 5021, the inclined surface of the second limiting tooth 5024 pushes the first limiting tooth 5014, or by pressing the ring body 5021 inward and rotating it, so that they are offset, thereby rotating the cam 5022 by a certain angle and changing the initial torque of the torsion spring 503. The first limiting tooth 5014 has eight triangular teeth distributed circumferentially. After the ring body 5021 stops rotating every 45°, the reset spring 504 drives the ring body 5021 to reset, and the second limiting tooth 5024 automatically engages in the first limiting tooth 5014 to complete the 45° limit.

[0030] like Figure 4 As shown, during the clockwise rotation of the left cam 5022, it will push the end of the torsion spring 503 upward, increasing its initial torque. Figure 5The disc body 5011 shown has a limiting protrusion 5013 protruding from its periphery. The ring body 5021 has a limiting strip 5025 located on the moving path of the limiting protrusion 5013. The height of the limiting strip 5025 is higher than the second limiting tooth 5024, which limits the rotation of the ring body 5021 to more than 315°, prevents the end of the torsion spring 503 from passing the position where the protruding part of the cam 5022 shrinks, and prevents the torque from decreasing rapidly and rebounding.

[0031] The adjustable torsion springs 503 on both sides can keep the opening speed of the two covers 2 closer in actual use, achieving basic synchronization and improving the user experience.

[0032] In addition, a retainer 5012 is provided on the inner side of the disc body 5011. The retainer 5012 is engaged with the mounting post 101, and the disc body 5011 is connected to the mounting post 101 by bolts, so that the mounting disc 501 is a detachable structure, which can be replaced after the triangular teeth are ground flat after long-term use.

[0033] The ring body 5021 extends outward from the circumference to form a handle 5023, which facilitates the user's operation and rotation of the ring body 5021.

[0034] The handrail 1 has a movable groove 103 at one end that corresponds to the cover plate 2. One end of the torsion spring 503 passes through the movable groove 103 and is locked on the cover plate 2, which limits the range of the torsion spring 503 that drives the cover plate 2 to rotate, so that the cover plate 2 is ultimately in a vertically upward state after it is opened.

[0035] The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and to design various embodiments with various modifications suitable for a particular purpose.
