Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a door handle structure and an all-terrain vehicle. Background Technology
[0002] All-terrain vehicles (ATVs) are light vehicles designed specifically for complex off-road terrain. Their design focuses on balancing passability, load capacity, and environmental adaptability, and they are widely used in rescue, military, recreational, and special operations.
[0003] Currently, the door handle structures of all-terrain vehicles are mainly divided into pull-cord door handles and rigid bar door handles, such as... Figure 1 and Figure 2 As shown, a pull-cord door handle connects the two ends of a soft cord to the door lock and the door frame, respectively. Pulling the middle of the cord opens the door. A rigid bar door handle, on the other hand, has a rigid bar directly connected to the door lock, which is opened by swinging the bar. However, because pull-cord door handles are made entirely of soft cord, it's easy to lose track of the handle when trying to open the door, affecting opening speed and compromising strength. Rigid bar door handles, due to the weight of the rigid bar and its rigid connection to the door lock, are susceptible to accidental unlocking due to the inertial force transmitted directly to the lock during vehicle bumps, compromising passenger safety. Furthermore, the shaking of the handle generates noise.
[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0011] In some embodiments, the torsion spring assembly includes a torsion spring body and a torsion spring pressure plate; the bearing post includes a first post segment and a second post segment with a diameter greater than that of the first post segment along the axial direction, the second post segment being connected to the seat plate; the torsion spring body is sleeved on the second post segment, and one torsion arm of the torsion spring body is connected to the handle body, and the other torsion arm abuts against the torsion spring limiting post; the bearing is movably connected to the first post segment; the torsion spring pressure plate is sleeved on the first post segment and is located axially between the bearing and the torsion spring body, for applying axial constraint to the torsion spring body.
[0012] In some embodiments, the handle assembly further includes a first bearing washer, a second bearing washer, and a fastener; the first bearing washer and the second bearing washer are axially spaced apart and sleeved on the first column section, and the bearing is axially located between the first bearing washer and the second bearing washer; the fastener is axially connected to the end of the first column section away from the second column section.
[0013] In some implementations, it also includes a cable loop, which is fixedly connected to the door frame and allows the cable to pass through to adjust the pulling direction of the cable on the door lock.

Detailed Implementation
[0022] In the description of this utility model, it should be understood that if terms such as "center," "inner," "outer," "axial," "radial," and "circumferential" appear, indicating orientation or positional relationship, unless otherwise specified, they are understood to be based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0023] Furthermore, features specified with "first" or "second" for descriptive purposes only should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Features specified with "first" or "second" may explicitly or implicitly include at least one of the specified features. The description of "multiple" generally means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0024] As mentioned above, in view of the shortcomings of traditional pull-cord door handles and rigid bar door handles in all-terrain vehicles, the general concept of this application is to provide a door handle structure 10. By combining the rigid support and positioning of the handle mechanism 200 and the base 100 with the flexible isolation transmission of the pull cable 300, the structure ensures intuitive and reliable operation and quick positioning. At the same time, it overcomes the defect of accidental unlocking of the door lock 30 under bumpy road conditions through a physical isolation mechanism and avoids noise caused by handle shaking.
[0025] Based on the above ideas, and referring to Figures 3 to 7 As shown, this application embodiment provides a car door handle structure 10, including: a base 100 for fixed connection with a car door frame 20; a handle mechanism 200 rotatably connected to the base 100; and a pull cable 300, one end of which is connected to the handle mechanism 200, and the other end of which is used to link with the door lock; wherein, the handle mechanism 200 is configured to be able to rotate a preset angle based on the base 100 to drive the pull cable 300 to trigger the door lock 30 to unlock.
[0026] It is understood that in this embodiment, the base 100 is fixed to the door frame 20, providing rigid support for the handle mechanism 200. The handle mechanism 200 is rotatably connected to the base 100, which can provide a clear operating position, ensuring the reliability and quick positioning of user operation. Furthermore, by flexibly isolating the transmission of the pull wire 300 to trigger the door lock 30 to unlock, the inertial force transmission path of the handle mechanism 200 to the door lock 30 can be cut off, avoiding accidental opening of the door lock 30, thereby improving safety. In addition, since the handle mechanism 200 and the base 100 form a rigid support, it is more conducive to eliminating noise caused by component shaking.
[0027] It should be noted that in this embodiment, the handle mechanism 200 is used to unlock the door lock 30. The pull cable 300 does not need to consider the feel of the touch. Therefore, the pull cable 300 can be a metal pull cable 300, such as a steel pull cable 300, to improve its service life.
[0028] To limit the maximum rotational stroke of the handle mechanism 200, refer to Figure 3 , Figure 4 and Figure 7As shown, in some embodiments, the base 100 includes a seat plate 110, a bearing post 120, and a handle limiting post 130; the seat plate 110 is fixedly connected to the door frame 20; the bearing post 120 is axially connected to the seat plate 110, and the handle mechanism 200 is rotatably connected to the bearing post 120; the handle limiting post 130 is axially connected to the seat plate 110 and is disposed on the rotation path of the handle mechanism 200, and can abut against the handle mechanism 200 when it rotates to a preset angle.
[0029] In this embodiment, the seat plate 110 serves as the connection interface between the base 100 and the door frame 20, primarily used for fixed connection with the door frame 20. The bearing post 120 and the handle limiting post 130 are both axially connected to the seat plate 110. The bearing post 120 and the handle limiting post 130 can be spaced apart in the height direction. The handle mechanism 200 is rotatably connected to the bearing post 120, while the handle limiting post 130 is located on the rotation path of the handle mechanism 200, at the end position of the rotation path of the handle mechanism 200. When the handle mechanism 200 is rotated to a preset angle by external force, the handle limiting post 130 abuts against the handle mechanism 200. At this time, the handle mechanism 200 cannot continue to rotate, and the pull cable 300 unlocks the door lock 30. This design can prevent the door lock 30 from being damaged due to excessive traction of the pull cable 300.
[0030] To achieve automatic reset and operational force control of the handle mechanism 200, refer to... Figure 4 , Figure 5 and Figure 7 As shown, in some embodiments, the base also includes a torsion spring limiting post 140 axially connected to the seat plate 110; the handle mechanism 200 includes a handle assembly 210 and a torsion spring assembly 220; the handle assembly 210 is rotatably connected to the bearing post 120, and the pull cable 300 is connected to the handle assembly 210; the torsion spring assembly 220 is sleeved on the bearing post 120 and is arranged axially between the handle assembly 210 and the seat plate 110, with one end of the torsion spring assembly 220 connected to the handle assembly 210 and the other end abutting against the torsion spring limiting post 140.
[0031] In this embodiment, the torsion spring limiting post 140 can be designed on one side of the bearing post 120 at the bottom of the handle limiting post 130, and spaced apart from the bearing post 120, to provide accommodating space for the installation of the torsion spring assembly 220. After the torsion spring assembly 220 is sleeved on the bearing post 120, one end of its torsion arm abuts against the torsion spring limiting post 140, while the other end of its torsion arm is connected to the handle assembly 210. The torsion spring assembly 220 can provide a preload to the handle assembly 210. This preload is designed to be greater than the maximum vibration inertial force of the handle assembly 210, so as to prevent the handle assembly 210 from rotating due to bumps during driving, which would cause the door lock 30 to be falsely triggered. Furthermore, by designing the torsion spring assembly 220, the handle assembly 210 needs to be subjected to the torque of the torsion spring assembly 220 during rotation. When the door lock 30 is triggered by rotating to a preset angle, it can automatically reset, thereby realizing the automatic reset of the handle mechanism 200 and the control of the operating force.
[0032] To achieve the rotation of the handle assembly 310, continue to refer to... Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the handle assembly 210 includes a handle body 211, a bearing seat 212, and a bearing 213; the bearing seat 212 is fixedly connected to the handle body 211, and the bearing 213 is press-fitted into the bearing seat 212 and movably connected to the bearing post 120; the handle body 211 is connected to one end of the torsion spring assembly 220 and to the pull cable 300, and can abut against the handle limiting post 130 when rotated to a preset angle.
[0033] In this embodiment, the handle body 211 is welded to the bearing seat 212, the bearing seat 212 has a bearing 213 mounting hole, the bearing 213 is press-fitted into the bearing 213 mounting hole, and the bearing 213 is movably connected to the bearing column 120 to facilitate the rotation of the handle body 211 based on the base 100; the handle body 211 is connected to one end of the torsion spring assembly 220 and to the pull wire 300, so that it is subjected to the pre-tightening force of the torsion spring assembly 220 when rotating, and drives the pull wire 300 to move during the rotation. When the handle body 211 rotates to a preset angle, it abuts against the handle limit post 130. At this time, the pull wire 300 drives the door lock to trigger unlocking.
[0034] refer to Figure 6As shown, in some embodiments, the handle body 211 includes a mounting part 2111, a gripping part 2112, and a traction part 2113; the mounting part 2111 has a bearing mounting hole R1, and the bearing seat 212 is fixedly connected in the bearing mounting hole R1; the gripping part 2112 is connected to the mounting part 2111, and a limiting groove R2 is formed between the gripping part 2112 and the mounting part 2111, the limiting groove R2 is used to abut against the handle limiting post 130; the traction part 2113 is connected to the mounting part 2111, and a pull cable mounting hole R3 is provided on the traction part 2113 for connecting to the pull cable 300; wherein, the mounting part 2111 also has a plurality of force adjustment holes R4, the force adjustment holes R4 are spaced apart along the rotation direction of the handle body 211, and one end of the torsion spring assembly 220 is connected in any one of the force adjustment holes R4.
[0035] In this embodiment, the handle body 211 is generally plate-shaped. The mounting part 2111, the gripping part 2112, and the traction part 2113 can be integrally formed. The mounting part 2111 is in the shape of a circular plate. A bearing seat mounting hole R1 is provided in the center of the mounting part 2111. The bearing seat 212 is welded into the bearing seat mounting hole R1. Multiple force adjustment holes R4 (e.g., 9 holes) are also provided in the circumferential direction of the bearing seat mounting hole R1. The multiple force adjustment holes R4 are spaced apart along the rotation direction of the handle body 211. These force adjustment holes R4 are mainly used to connect one of the torsion arms of the torsion spring assembly 220 to adjust the preload provided by the torsion spring assembly 220, so that the operating force of the handle body 211 is more flexible.
[0036] The gripping part 2112 is connected to the mounting part 2111, and a limiting groove R2 is formed between the gripping part 2112 and the mounting part 2111. The limiting groove R2 faces the handle limiting post 130 so that it abuts against the handle limiting post 130 when the handle body 211 rotates to a preset angle to form a limit. The traction part 2113 is connected to the mounting part 2111, and a pull cable mounting hole R3 is provided on the traction part 2113 for connecting to the pull cable 300 so as to pull the pull cable 300 during the rotation of the handle body 211.
[0037] In this embodiment, the gripping part 2112 and the traction part 2113 can be provided with several elongated weight-reducing holes to reduce the weight of the handle body 211, reduce the inertial force generated by the handle body 211 when subjected to bumps, and enable the torsion spring assembly 220 to provide a lower preload force. This avoids the door lock 30 from being accidentally triggered, while also making the force exerted by the handle body 211 during operation lower and easier to operate to trigger the door lock 30 to unlock.
[0038] refer to Figure 4 , Figure 5 and Figure 7As shown, in some embodiments, the torsion spring assembly 220 includes a torsion spring body 221 and a torsion spring pressure plate 222; the bearing column 120 includes a first column segment 121 and a second column segment 122 with a diameter larger than the first column segment 121 along the axial direction, and the second column segment 122 is connected to the seat plate 110; the torsion spring body 221 is sleeved on the second column segment 122, and one torsion arm of the torsion spring body 221 is connected to the handle body 211, and the other torsion arm abuts against the torsion spring limiting post 140; the bearing 213 is movably connected to the first column segment 121; the torsion spring pressure plate 222 is sleeved on the first column segment 121 and is located axially between the bearing 213 and the torsion spring body 221, for applying axial constraint to the torsion spring body 221.
[0039] In this embodiment, the torsion spring body 221 mainly consists of a long torsion arm, a short torsion arm, and a spring coil connected between the long torsion arm and the short torsion arm. The spring coil is sleeved on the second column segment 122. The short torsion arm of the torsion spring body 221 abuts against the bottom of the circumferential surface of the torsion spring limiting post 140, while the long torsion arm is connected to a force adjustment hole R4 of the handle body 211. The torsion spring pressure plate 222 is sleeved on the end of the first column segment 121 near the second column segment 122 to apply axial constraint to the torsion spring body 221.
[0040] In this embodiment, the second column segment 122, which is responsible for fixing the torsion spring body 221, has a larger diameter to provide a stable torsional fulcrum. The first column segment 121, which is mainly used to install the bearing 213, has a smaller diameter to help reduce the coefficient of rotational friction.
[0041] refer to Figure 4 and Figure 5 As shown, in some embodiments, the handle assembly 210 further includes a first bearing washer 214, a second bearing washer 215, and a fastener 216; the first bearing washer 214 and the second bearing washer 215 are spaced apart axially and sleeved on the first column segment 121, and the bearing 213 is located axially between the first bearing washer 214 and the second bearing washer 215; the fastener 216 is axially connected to the end of the first column segment 121 away from the second column segment 122.
[0042] In this embodiment, the first bearing washer 214 and the second bearing washer 215 are mainly used to form an axial constraint on the bearing 213 to prevent the handle body 211 from shaking and reduce noise. The fastener 216 can be a fastening nut. The end of the first column segment 121 away from the second column segment 122 can be designed with an external thread that is compatible with the fastening nut. Thus, during assembly, by tightening the fastening nut, the first bearing washer 214, the bearing 213, the second bearing washer 215 and the torsion spring pressure plate 222 can be axially locked onto the first column segment 121.
[0043] Therefore, during assembly, the base 100 can be welded to the door frame. The handle body 211, bearing seat 212 and bearing 213 are pre-assembled into a combination. Then, the torsion spring body 221 is fitted onto the second column section 122 and the short torsion arm is attached to the bottom of the torsion spring limiting post 140. The torsion spring pressure plate 222, the second bearing washer 215 and the pre-assembled combination are installed on the first column section 121 in sequence along the axial direction. The long torsion arm of the torsion spring body 221 is pressed into the force adjustment hole R4. The first bearing washer 214 is then installed and the fastener 216 is tightened to complete the assembly of the handle mechanism 200 and the base 100. Finally, the pull cable 300 is connected to the handle body 211 and the door lock 30 respectively.
[0044] refer to Figure 3 As shown, in some embodiments, the door handle structure 10 further includes a winding ring 400, which is fixedly connected to the door frame 20 and allows the pull cable 300 to pass through and adjust the pulling direction of the pull cable 300 on the door lock 30.
[0045] The cable loop 400 can be fixed on the door frame 20. It is mainly used to change the pulling direction of the cable 300 on the door lock 30 after the cable 300 passes through, so that the base 100 and the handle mechanism 200 are more flexible in position.
[0046] refer to Figure 3 and Figure 8 As shown, another embodiment of this application provides an all-terrain vehicle 1, including the door handle structure 10 as described above, as well as a door frame 20 and a door lock 30; the base 100 is fixedly connected to the door frame 20, and the door lock 30 is connected to the pull cable 300 so that it can be triggered by the pull cable 300 to unlock when the handle mechanism 200 is rotated to a preset angle.
[0047] In some embodiments, the base 100 is arranged at intervals along the height direction on the top of the door lock 30. When the door lock 30 is pulled up to unlock, one end of the pull cable 300 is connected to the handle mechanism 200 and the other end is connected to the door lock 30. When the handle mechanism 200 rotates, it directly drives the pull cable 300 to move upward, thereby driving the door lock 30 to be pulled up to unlock.
[0048] In other embodiments, the base 100 is spaced apart on the top of the door lock 30 along the height direction. When the door lock 30 is pressed down to unlock, the winding ring 400 of the door handle structure 10 is spaced apart on the bottom of the door lock 30 along the height direction. One end of the pull cable 300 is connected to the handle mechanism 200, and the other end passes through the winding ring 400 and connects to the door lock 30. When the handle mechanism 200 rotates, it drives the pull cable 300 to move upward near the handle mechanism 200. The other end of the pull cable 300 after being bent through the winding ring 400 is connected to the door lock. This other end moves downward, thereby driving the door lock 30 to be pressed up to unlock.
[0049] In summary, the door handle structure 10 provided in this application embodiment ensures intuitive and reliable operation and quick positioning, while preventing the door lock 30 from being accidentally unlocked under bumpy road conditions, and eliminating handle shaking noise.
[0050] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
