Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vehicle parts technology, and relates to a rotating handle for vehicles and vehicles. Background Technology
[0002] A vehicle handle is a gripping device used on a vehicle to help passengers maintain their balance while the vehicle is in motion.
[0003] Currently, there are some rotatable soft handles (i.e., hand strap handles) on the market, such as an invention patent with application number CN201420848215.4 entitled "A Rotating Handle for Automobiles". This handle has a rotatable pull strap that can rotate about 90° around a horizontal axis from a lateral posture (folded state) that fits against the roof to a vertical downward use posture, making it easier for passengers to grip.
[0004] Although the handle has a rotating function, its movement is limited to a single plane of rotation, meaning it can only rotate around one axis and cannot be adjusted in multiple directions. Therefore, it is difficult to adjust the handle to a more ergonomic grip angle. Utility Model Content
[0005] The purpose of this utility model is to address the aforementioned problems existing in the prior art by proposing a rotating handle for vehicles and a vehicle.
[0006] The objective of this utility model can be achieved through the following technical solution: a rotating handle for vehicles, comprising:
[0007] Fixed base;
[0008] A first rotating seat, which is hinged to the fixed seat via a first rotating shaft;
[0009] The second rotating seat is hinged to the first rotating seat via a second rotating shaft;
[0010] A handle strap, the end of which is fixedly connected to the second rotating seat;
[0011] Wherein, the axis of the first rotating shaft is not parallel to the axis of the second rotating shaft; the handle strap has a first rotational degree of freedom to rotate about the first rotating shaft and a second rotational degree of freedom to rotate about the second rotating shaft.
[0012] Preferably, the travel position of the first rotating seat includes a storage position, and when the first rotating seat is in the storage position, the first rotating seat overlaps with the fixed seat; the travel position of the second rotating seat includes a folded position, and when the second rotating seat is in the folded position, the second rotating seat is flush with the first rotating seat.
[0013] Preferably, the first rotating shaft is fitted with a first torsion spring, the two ends of the first torsion spring being connected to the first rotating seat and the fixed seat respectively, and the first torsion spring applying a torque to the first rotating seat to move it toward the storage position; the second rotating shaft is fitted with a second torsion spring, the two ends of the second torsion spring being connected to the first rotating seat and the second rotating seat respectively, and the second torsion spring applying a torque to the second rotating seat to move it toward the folding position.
[0014] Preferably, one of the fixed seat and the first rotating seat is provided with a limiting block and the other is provided with two limiting parts. The area between the two limiting parts is a travel interval. The limiting block is located in the travel interval. When the limiting block abuts against the limiting part, it restricts the first rotating seat from rotating relative to the fixed seat.
[0015] Preferably, the first rotating shaft is integrally connected to the first rotating seat, the first rotating shaft passes through the fixed seat, the first rotating shaft is fitted with a first axial locking member, the first axial locking member is axially locked with the first rotating shaft, and the first axial locking member abuts against the fixed seat to restrict the separation of the fixed seat from the first rotating seat.
[0016] Preferably, the mounting base is equipped with a damper, and the first rotating shaft is connected to the damper.
[0017] Preferably, the second rotating seat is provided with at least two locking pins, the locking pins passing through the handle strap, the locking pins being fitted with a second axial locking member, the second axial locking member being axially locked with the locking pin, and the second axial locking member abutting against the handle strap to restrict the handle strap from separating from the locking pin.
[0018] Preferably, the handle strap includes a rigid frame and a covering layer, the covering layer covering the surface of the rigid frame.
[0019] Preferably, the first rotating shaft is perpendicular to the second rotating shaft.
[0020] A vehicle includes the aforementioned rotary handle, and also includes a body having a roof, wherein a mounting base for the rotary handle is mounted on the roof.
[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0022] 1. The rotating handle has two different rotation angles. The handle can be adjusted in multiple directions by superimposing the two rotation angles, making it more flexible to use and easy to adjust the handle to a more ergonomic grip angle.
[0023] 2. The second degree of rotational freedom has been added, allowing the handle strap to swing and adjust in the left and right directions via the second rotating seat. This naturally accommodates the lateral position of different passengers and reduces the stress at the joint between the handle strap and the second rotating seat.
[0024] 3. The second torsion spring applies a constant restoring force to the second rotating seat, causing it to automatically return to the folded position when no external force is applied, eliminating the need for manual reset by the user and simplifying the operation process. Furthermore, the second torsion spring prevents the second rotating seat from accidentally unfolding due to bumps during travel. Attached Figure Description

Detailed Implementation
[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0035] like Figures 1 to 7 As shown, a car rotary handle includes:
[0036] Fixed base 100;
[0037] The first rotating seat 200 is hinged to the fixed seat 100 via a first rotating shaft 210;
[0038] The second rotating seat 300 is hinged to the first rotating seat 200 via a second rotating shaft 310;
[0039] The handle belt 400 is fixedly connected to the second rotating seat 300 at its end.
[0040] The axis of the first rotating shaft 210 is not parallel to the axis of the second rotating shaft 310; the handle belt 400 has a first rotational degree of freedom to rotate around the first rotating shaft 210 and a second rotational degree of freedom to rotate around the second rotating shaft 310.
[0041] The fixed base 100 is preferably a base structure made of robust metal or high-strength plastic. The fixed base 100 is used for fixed connection to the vehicle roof and provides a stable hinge point for the first rotating base 200, bearing all tension and torque applied by the user. The first rotating base 200 is a rotatable component that can rotate relative to the fixed base 100 about a first pivot 210, while simultaneously supporting the second rotating base 300 and the handle strap 400. The movement of the first rotating base 200 determines the swing of the handle strap 400 in a first direction (forward / backward or up / down). The second rotating base 300 is also a rotatable component that can rotate relative to the first rotating base 200 about a second pivot 310, allowing the handle strap 400 to swing in a second direction (left / right). The second rotating base 300 can also transmit and superimpose the movement of the first rotating base 200 onto the handle strap 400.
[0042] The first rotating shaft 210 provides the rotation center for the first degree of rotational freedom, and the second rotating shaft 310 provides the rotation center for the second degree of rotational freedom. The end of the handle 400 is firmly fixed to the second rotating seat 300, allowing the user to reach into the handle 400 for gripping. The handle 400 has a certain rigidity and will not sag naturally due to gravity, and it provides a comfortable gripping area.
[0043] The core working principle of the handle lies in the superposition of two non-parallel rotational degrees of freedom. The first rotating seat 200 can be held in the retracted position by damping, a limiting structure, or a slight preload, thereby keeping the handle strap 400 in its initial position. When the user reaches out and grasps the handle strap 400, a force is applied to the handle strap 400 according to their body position and needs. One component of this force causes the first rotating seat 200 to rotate around the first axis 210, thereby causing the handle strap 400 to rotate in the first rotational degree of freedom. At the same time, the other component of the force drives the second rotating seat 300 to rotate relative to the first rotating seat 200 around the second axis 310, thereby causing the handle strap 400 to rotate in the second rotational degree of freedom.
[0044] In actual use, the handle strap 400 is in a roughly horizontal state. The user's hand passes through the handle strap 400 and pulls it. The rotation of the first rotating seat 200 causes the handle strap 400 to rotate to a roughly vertical state. At the same time, the handle strap 400 can swing left and right through the second rotating seat 300, so as to conveniently adjust the handle strap 400 to a more ergonomic grip angle.
[0045] Compared to traditional rotating handles, this handle greatly expands the range of motion and accessible spatial positions of the handle belt 400 through two non-parallel rotational degrees of freedom. Whether the passenger is tall or short, whether they need to lean forward and upward when getting on the vehicle, or need to stabilize their body to the side while the vehicle is in motion, they can easily and comfortably find a suitable grip point.
[0046] It should be further noted that the ingenuity of this design lies in the addition of a second rotational degree of freedom to the existing one, allowing the handle strap 400 to swing and adjust in the left and right directions via the second rotating seat 300. This naturally accommodates the lateral positions of different passengers and reduces the stress at the joint between the handle strap 400 and the second rotating seat 300.
[0047] Preferably, the mounting base 100 is provided with at least one connecting portion 110. The connecting portion 110 can be fixedly connected to the vehicle roof by screws.
[0048] like Figures 1 to 3 As shown, based on the above embodiment, the first rotating shaft 210 is integrally connected with the first rotating seat 200. The first rotating shaft 210 passes through the fixed seat 100. The first rotating shaft 210 is fitted with a first axial locking member 220. The first axial locking member 220 is axially locked with the first rotating shaft 210. The first axial locking member 220 abuts against the fixed seat 100, thereby restricting the separation of the fixed seat 100 and the first rotating seat 200.
[0049] The first axial locking element 220 can be configured as a snap ring, a shaft retaining ring, a nut, etc. The first rotating seat 200 cooperates with the first axial locking element 220 to clamp the fixed seat 100, thereby locking the fixed seat 100 and the first rotating seat 200 together axially. This design allows the first rotating seat 200 to rotate relative to the fixed seat 100 around the first rotating shaft 210, and prevents the first rotating shaft 210 from being pulled out of the fixed seat 100.
[0050] like Figure 1 , Figure 4 , Figure 5 As shown, based on the above embodiment, the second rotating seat 300 is provided with at least two locking pins 320. The locking pins 320 pass through the handle belt 400. The locking pins 320 are fitted with a second axial locking member 330. The second axial locking member 330 is axially locked with the locking pin 320. The second axial locking member 330 abuts against the handle belt 400, thereby restricting the handle belt 400 from separating from the locking pin 320.
[0051] The second axial locking member 330 can be configured as a snap ring, shaft retaining ring, nut, etc. The second rotating seat 300 cooperates with the second axial locking member 330 to clamp the handle belt 400, so that the handle belt 400 and the second rotating seat 300 are locked together axially.
[0052] like Figures 1 to 7 As shown, based on the above embodiment, the handle strap 400 includes a rigid frame and a covering layer, with the covering layer covering the surface of the rigid frame.
[0053] The rigid frame, typically made of metal strips (such as stainless steel or aluminum alloy) or high-strength plastic strips, is positioned along the length of the handle strap 400 to provide structural support. It is wrapped around the surface of the rigid frame, usually made of fabric, leather, silicone, or soft plastic. This covering enhances the feel and aesthetics, and protects the frame from wear and tear. If the handle strap 400 were made entirely of flexible materials, it would naturally sag under its own weight when stored. The rigid frame provides bending stiffness to the handle strap 400, preventing it from sagging under its own weight when stored.
[0054] like Figures 1 to 7 As shown, based on the above implementation method, the first rotation axis 210 is perpendicular to the second rotation axis 310. It should be noted that, here, "perpendicular" means that the dot product of the direction vectors of the two rotation axis axes in three-dimensional space is zero.
[0055] Based on the above embodiments, the travel position of the first rotating seat 200 includes the storage position. When the first rotating seat 200 is in the storage position, the first rotating seat 200 overlaps with the fixed seat 100.
[0056] In the folded state, the first rotating seat 200 and the fixed seat 100 completely overlap, avoiding the need for additional vertical or horizontal space. The overlapping design simplifies the overall structural layout and reduces redundant space between components. Furthermore, in the overlapping state, the contact surface between the first rotating seat 200 and the fixed seat 100 is larger, allowing for positioning through friction. The first rotating seat 200 can also rotate to the usable position (vertical position).
[0057] Based on the above embodiments, the travel position of the second rotating seat 300 includes a folded position. When the second rotating seat 300 is in the folded position, the second rotating seat 300 is flush with the first rotating seat 200.
[0058] The second rotating seat 300 being flush with the first rotating seat 200 means that their surfaces are on the same plane or parallel to each other, making the contour surfaces of the second rotating seat 300 and the first rotating seat 200 smoother. Structurally, when the first rotating seat 200 is in the stowed position and the second rotating seat 300 is in the folded position, the second rotating seat 300 is in close contact with the surface of the fixed seat 100, causing the second rotating seat 300 to overlap with the fixed seat 100. When the second rotating seat 300 is in other positions, the second rotating seat 300 is raised relative to the first rotating seat 200, and the second rotating seat 300 can rotate to the unfolded position (limit position).
[0059] like Figures 1 to 7 As shown, based on the above embodiment, a first torsion spring 230 is provided on the first rotating shaft 210. The two ends of the first torsion spring 230 are respectively connected to the first rotating shaft 210 and the fixed seat 100, thereby applying an elastic force to the first rotating seat 200 to make it tend to the storage position; a second torsion spring 340 is sleeved on the second rotating shaft 310. The two ends of the second torsion spring 340 are respectively connected to the first rotating seat 200 and the second rotating seat 300, and the second torsion spring 340 applies a torque to the second rotating seat 300 to make it tend to the folding position.
[0060] The first torsion spring 230 applies a constant restoring force to the first rotating seat 200, causing it to automatically return to its folded position when no external force is applied. The second torsion spring 340 applies a constant restoring force to the second rotating seat 300, causing it to automatically return to its folded position when no external force is applied, eliminating the need for manual reset by the user and simplifying the operation process. Furthermore, the first torsion spring 230 prevents the first rotating seat 200 from accidentally rotating due to bumps during travel, and the second torsion spring 340 prevents the second rotating seat 300 from accidentally unfolding due to bumps during travel.
[0061] Based on the above embodiment, a damper 120 is installed on the fixed base 100, and the first rotating shaft 210 is connected to the damper 120. The damper 120 can provide rotational resistance, making the first rotating seat move more smoothly when rotating around the first rotating shaft.
[0062] like Figures 1 to 8 As shown, based on the above embodiment, one of the fixed seat 100 and the first rotating seat 200 is provided with a limiting block 240 and the other is provided with two limiting parts 130. The area between the two limiting parts 130 is the travel interval. The limiting block 240 is located in the travel interval. When the limiting block 240 abuts against the limiting part 130, it restricts the first rotating seat 200 from rotating relative to the fixed seat 100.
[0063] The area between the two limiting parts 130 constitutes a travel range, within which the limiting block 240 can move. When the limiting block 240 abuts against either of the limiting parts 130, it can restrict the first rotating seat 200 from continuing to rotate, thereby limiting the two extreme travel positions of the first rotating seat 200. Specifically, when the first rotating seat 200 is in the retracted position, the limiting block 240 abuts against one of the limiting parts 130; when the first rotating seat rotates to its extreme position, the limiting block 240 abuts against the other limiting part 130.
[0064] like Figures 1 to 7 As shown, based on the above embodiments, a vehicle includes a rotating handle and a vehicle body with a roof. The mounting base 100 of the rotating handle is installed on the roof.
[0065] The mounting base 100 is directly installed on the ceiling, and its mounting part is fixedly connected to the ceiling by screws or clips. In the folded state, the handle strap 400 is horizontally flush against the ceiling, not occupying passenger space. When in use, the user holds the handle strap 400, which rotates around the first pivot 210 via the first rotating base 200 and the second rotating base 300, thus rotating to a vertical position. The handle strap 400 can then be adjusted left and right by swinging the second rotating base 300. Because the two pivots are perpendicularly intersecting, the end of the handle strap 400 can move in three-dimensional space, automatically adjusting to the most comfortable angle.
[0066] After use, the second torsion spring 340 at the second pivot 310 applies elastic force to the second rotating seat 300, causing it to automatically return to the folded position when there is no external force. Then, the first rotating seat 200 can be manually or under the action of elastic force to return to the storage position.
[0067] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0068] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0069] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0070] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
