DETAILED DESCRIPTION

[0033] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0034] Related art uses a four-link hinge mechanism for a horizontally extending and rotating wing door. However, this hinge mechanism requires installation on the side of the vehicle body and has a complex structure.

[0035] In order to solve the above technical problems, with reference to Figures 1 to 3, some embodiments of the present disclosure provide a vehicle door hinge 100. The vehicle door hinge includes a mounting seat 101. The mounting seat 101 is used to connect with the vehicle body 001. The vehicle door hinge 100 also includes a telescopic member 107, which is movably connected to the mounting seat 101, and the end of the telescopic member 107 away from the vehicle body 001 is used to connect with the vehicle door 002. The vehicle door hinge 100 also includes a driving assembly 500, which is connected to the telescopic member 107 and is used to drive the telescopic member 107 to rotate and make the telescopic member 107 reciprocate along the rotation axis of the telescopic member 107.

[0036] In some embodiments, the rotation axis of the telescopic member 107 is parallel to the width direction of the vehicle body 001. The mounting base 101 can be a hollow cylindrical structure, and the telescopic member 107 can be a cylindrical rotating shaft structure. The telescopic member 107 is disposed in the hollow cavity of the mounting base 101 and is movably connected to the mounting base 101.

[0037] Figure 1 shows a schematic diagram of a door hinge in use, at which time the door 002 is in a closed state; as shown in Figure 1 , the door hinge is arranged between the vehicle body 001 and the door 002 along the width direction of the vehicle body 001, and the door hinge is located at the lower left corner of the door 002.

[0038] For example, the mounting seat 101 can be fixed to the vehicle body 001 by bolts, and the end of the telescopic member 107 extending from the mounting seat 101 can also be fixed to the vehicle door 002 by bolts. The rotation axis direction of the telescopic member 107 is parallel to the width direction of the vehicle body 001, and the driving component 500 provides power for the telescopic member 107 to rotate and reciprocate along its own rotation axis direction.

[0039] The telescopic member 107 can rotate while moving back and forth along the width direction of the vehicle body 001, so that the mounting seat 101 and the telescopic member 107 form a linear hinge structure; the mounting seat 101 is set between the vehicle body 001 and the door 002 along the width direction of the vehicle body 001, one end of the mounting seat 101 is fixedly connected to the vehicle body 001, and the telescopic member 107 extends out of the mounting seat 101 and is fixedly connected to the door 002.

[0040] When the car door 002 is opened, the drive assembly 500 drives the telescopic member 107 to move and rotate along the width direction of the car body 001 toward the side away from the car body 001, so that the car door 002 rotates upward while moving away from the car body 001 until the car door 002 is fully opened.

[0041] When the door 002 is closed, the drive assembly 500 drives the telescopic member 107 to move and rotate along the width direction of the vehicle body 001 toward the side close to the vehicle body 001, so that the door 002 rotates downward while moving toward the side close to the vehicle body 001 until the door 002 is completely closed.

[0042] In some embodiments of the present disclosure, the door 002 can be opened and closed by adopting the above-mentioned door hinge. Compared with the related art, some embodiments of the present disclosure arrange the door hinge along the width direction of the vehicle body 001, thereby reducing the horizontal space parallel to the door 002 occupied by the installation of the hinge structure, so as to be suitable for situations where there is insufficient space in the horizontal direction parallel to the door 002.

[0043] In some embodiments, a guide structure is provided between the mounting seat 101 and the telescopic member 107 , and when the telescopic member 107 reciprocates along its own rotation axis, the guide structure is used to rotate the telescopic member 107 .

[0044] In some embodiments, the guide structure can be regarded as a part of the driving assembly 500. Under the action of the guide structure, the telescopic member 107 can rotate while moving along the width direction of the vehicle body 001, thereby driving the vehicle door 002 to open and close.

[0045] In some embodiments of the present disclosure, a guide structure is provided between the mounting seat 101 and the telescopic member 107 so that the driving assembly 500 only needs to provide a linear driving force for the reciprocating movement of the telescopic member 107 along the width direction of the vehicle body 001, thereby simplifying the power structure of the driving assembly 500.

[0046] In some embodiments, the guide structure includes a first guide portion and a second guide portion, the first guide portion is connected to the mounting seat 101, the second guide portion is connected to the telescopic member 107, and the first guide portion and the second guide portion cooperate with each other.

[0047] In some embodiments, the first guide portion can be a protrusion on the mounting seat 101, and the second guide portion can be a groove on the telescopic member 107. The groove and the protrusion cooperate with each other to limit the movement direction of the telescopic member 107, so that the telescopic member 107 can rotate while moving along the width direction of the vehicle body 001, thereby driving the vehicle door 002 to close and open.

[0048] Correspondingly, the first guide portion can also be a groove on the mounting seat 101, and the second guide portion can be a protrusion on the telescopic member 107. The groove and the protrusion cooperate with each other to limit the movement direction of the telescopic member 107, so that the telescopic member 107 can rotate while moving back and forth along the width direction of the vehicle body 001, thereby driving the vehicle door 002 to close and open.

[0049] In addition, some embodiments of the present disclosure do not limit the structure of the first guide part and the second guide part. Those skilled in the art can flexibly set them according to needs. They only need to make the first guide part and the second guide part cooperate with each other so that the telescopic part 107 can rotate while moving along the width direction of the vehicle body 001.

[0050] In some embodiments, referring to FIG. 3 and FIG. 4 , the first guide portion is a spiral guide groove 108 , and the second guide portion is a rolling body 105 , and the spiral guide groove 108 and the rolling body 105 cooperate with each other.

[0051] In some embodiments, the rolling body 105 can be a sphere; the spiral guide groove 108 can be arranged on the circumferential side of the telescopic member 107, and the rolling body 105 is arranged between the telescopic member 107 and the mounting seat 101. The rolling body 105 contacts the groove wall of the spiral guide groove 108 to limit the movement direction of the telescopic member 107, so that the telescopic member 107 rotates while moving back and forth along the width direction of the vehicle body 001, thereby driving the door 002 to open or close.

[0052] When the telescopic member 107 reciprocates along the width direction of the vehicle body 001 , the rolling body 105 can rotate freely, thereby reducing wear and collision between the rolling body 105 and the telescopic member 107 .

[0053] In this case, the drive assembly 500 further includes a drive mechanism that provides a linear drive force for the telescopic member 107 to move along the width direction of the vehicle body 001. The drive mechanism can be any power element capable of providing a linear drive force, such as a hydraulic cylinder, an electric push rod, or a screw jacking mechanism, and is not limited in this disclosure.

[0054] In addition, the rotation angle of the door 002 can be adjusted by adjusting various parameters of the spiral guide groove 108. For example, when the telescopic member 107 moves 150 mm along its own axis, the telescopic member 107 can simultaneously rotate 90 degrees with the help of the spiral guide groove 108 and the rolling element 105, thereby driving the door 002 to rotate 90 degrees.

[0055] In some embodiments of the present disclosure, the door hinge is arranged between the vehicle body 001 and the vehicle door 002 along the width direction of the vehicle body 001. Compared with the related art, the horizontal space occupied by the hinge structure for installing is reduced, thereby solving the problem in the related art that the hinge mechanism is not suitable for the situation where there is insufficient space for setting in the horizontal direction parallel to the vehicle door 002; and, compared with the complex gear design in the related art, the door hinge in some embodiments of the present disclosure is guided by rolling elements 105 and spiral guide grooves 108, and the structural design is simple. Moreover, during the side opening and rotation of the vehicle door 002, there is no vibration and noise caused by the meshing of the gear teeth.

[0056] 3 and 4 , the mounting seat 101 is provided with a mounting hole for accommodating at least part of the telescopic member 107 , and a rolling body 105 is provided on the wall of the mounting hole; and a spiral guide groove 108 is provided on the side wall of the telescopic member 107 .

[0057] In some embodiments, a mounting hole for accommodating the telescopic member 107 is provided on the mounting base 101, which can improve the compactness of the entire hinge structure and utilize the miniaturized design of the hinge structure to improve space utilization.

[0058] In some embodiments, referring to Figures 5 and 6 , the vehicle door hinge further comprises a retainer 104. Retainer 104 is disposed within the mounting hole and is provided with a through-hole 109 through which telescopic member 107 passes. Retainer 104 is used to confine rolling element 105 between telescopic member 107 and the wall of the mounting hole. Retainer 104 is provided with through-hole 109 into which rolling element 105 is at least partially embedded. The diameter of through-hole 109 is smaller than that of rolling element 105. The wall of the mounting hole is provided with rolling grooves 110 into which rolling element 105 is at least partially embedded. Rolling grooves 110 are provided in a one-to-one correspondence with through-holes 109.

[0059] In some embodiments, at least one group of retaining frames 104 are provided inside the mounting seat 101, and a plurality of through holes 109 are evenly provided on the retaining frames 104 along their own circumference. Each through hole 109 is provided in one-to-one correspondence with each rolling groove 110, and each rolling body 105 is respectively embedded in the accommodating cavity formed by the corresponding through hole 109 and the rolling groove 110, and a rotation gap is left between the groove wall of the rolling groove 110 and the rolling body 105.

[0060] The holder 104 is fixedly connected to the mounting seat 101 , specifically by welding, so as to fix the position of the holder 104 and prevent the holder 104 from moving when the telescopic member 107 moves, thereby affecting the normal operation of the telescopic member 107 .

[0061] In some embodiments of the present disclosure, the coaxiality between the telescopic member 107 and the mounting seat 101 is improved by the retaining frame 104, thereby improving the movement smoothness of the telescopic member 107; the diameter of the through hole 109 on the retaining frame 104 is smaller than the diameter of the rolling body 105, so as to confine the rolling body 105 in the through hole 109. When the telescopic member 107 is separated from the rolling body 105, the rolling body 105 can be prevented from falling out of the through hole 109 and affecting the subsequent normal operation of the telescopic member 107.

[0062] In addition, in order to reduce the wear between the rolling element 105 and the groove wall of the spiral guide groove 108, the cross-sectional diameter of the spiral guide groove 108 is made 1mm to 5mm larger than the diameter of the rolling element 105, thereby reserving a rolling gap between the rolling element 105 and the groove wall of the spiral guide groove 108.

[0063] In some embodiments, referring to FIG. 5 and FIG. 6 , there are a plurality of retaining frames 104 , and the plurality of retaining frames 104 are spaced apart along the rotation axis direction of the telescopic member 107 .

[0064] In some embodiments, the number of the retaining frames 104 may be one or more. By increasing the number of the retaining frames 104 , the stability of the movement of the telescopic member 107 may be improved.

[0065] In some embodiments, there are multiple retaining frames 104 , and the multiple retaining frames 104 are arranged at equal intervals along the rotation axis direction of the telescopic member 107 , thereby further improving the stability of the movement of the telescopic member 107 .

[0066] In some embodiments, referring to FIG. 3 and FIG. 6 , the inner diameter of the end of the mounting base 101 away from the vehicle body 001 is 0.1 mm to 0.5 mm larger than the diameter of the telescopic member 107 .

[0067] In some embodiments, the inner wall of the mounting seat 101 near the vehicle door 002 protrudes inward to form a ring, so that the inner diameter of the end is reduced and fits against the side wall of the telescopic member 107. When the telescopic member 107 is partially rotated outward from the mounting seat 101, the mounting seat 101 near the vehicle door 002 can provide support for the telescopic member 107 to improve the coaxiality of the telescopic member 107 and the mounting seat 101.

[0068] In some embodiments of the present disclosure, the inwardly protruding portion of the mounting seat 101 has an axial dimension of 15 mm, and the gap between the protruding portion and the telescopic member 107 is maintained between 0.1 mm and 0.5 mm.

[0069] In some embodiments, a plurality of spiral guide grooves 108 are provided on the side wall of the telescopic member 107 along its circumference, and each rolling element 105 on the same retaining frame 104 is respectively embedded in a different spiral guide groove 108 .

[0070] For example, a plurality of spiral guide grooves 108 are provided on the side wall of the telescopic member 107 , and the plurality of spiral guide grooves 108 are evenly distributed along the circumference of the telescopic member 107 . By increasing the number of the spiral guide grooves 108 , the movement stability of the telescopic member 107 can be improved.

[0071] In some embodiments, referring to Figures 3 and 6 , the drive assembly 500 further includes a hydraulic cylinder 102 and a hydraulic rod 103. The hydraulic cylinder 102 is disposed within the mounting hole. The hydraulic rod 103 is coaxially disposed with the hydraulic cylinder 102, slidably connected to the hydraulic cylinder 102 along its own axis, and is capable of rotating about its own axis. The end of the hydraulic rod 103 extending from the hydraulic cylinder 102 is fixedly connected to the telescopic member 107.

[0072] In some embodiments, the hydraulic cylinder body 102 is coaxially arranged in the mounting seat 101, and a base is welded to the end of the hydraulic cylinder body 102 close to the vehicle body 001. The base is provided with multiple bolt holes along its circumference, so that the hydraulic cylinder body 102 can be fixed to the vehicle body 001 with the help of bolts.

[0073] The hydraulic rod 103 is axially slidably connected to the hydraulic cylinder 102 and is rotationally connected to the hydraulic cylinder 102, allowing the hydraulic rod 103 to rotate freely about its own axis. The end of the hydraulic rod 103 extending from the hydraulic cylinder 102 is fixedly connected to the telescopic member 107, for example, by welding or threading, which is not limited in this disclosure.

[0074] When the car door 002 is opened, the hydraulic cylinder 102 drives the hydraulic rod 103 to extend, and the hydraulic rod 103 pushes the telescopic member 107 to move along the width direction of the car body 001 toward the side away from the car body 001, and the telescopic member 107 rotates around its own axis under the action of the spiral guide groove 108 and the rolling body 105 until the car door 002 is completely opened.

[0075] When the car door 002 is closed, the hydraulic cylinder 102 drives the hydraulic rod 103 to retract, and the hydraulic rod 103 pulls the telescopic member 107 to move along the width direction of the car body 001 toward the side close to the car body 001, and the telescopic member 107 rotates around its own axis under the action of the spiral guide groove 108 and the rolling body 105 until the car door 002 is completely closed.

[0076] Some embodiments of the present disclosure use a hydraulic cylinder to drive the telescopic member 107 to move. Compared with related technologies, not only is the process control accuracy high, but the door 002 can also be stably rotated and stopped at any position during the process of opening and closing the door 002.

[0077] In some embodiments, referring to FIG3 and FIG6 , a cavity is provided in the telescopic member 107 , and the hydraulic cylinder body 102 is provided in the cavity.

[0078] For example, a cavity is coaxially provided in the telescopic member 107 , and when the vehicle door 002 is in a fully closed state, most of the hydraulic cylinder body 102 is placed in the cavity.

[0079] An end fastener 106 is provided at one end of the telescopic member 107 close to the vehicle door 002, and the end fastener 106 blocks the end opening of the telescopic member 107. The end fastener 106 and the telescopic member 107 can be fixed as an integral part by welding, or fixed as an integral part by a snap-fit ​​structure. The present disclosure does not limit this. It is only necessary to fix the end fastener 106 and the telescopic member 107 as an integral part and prevent relative movement.

[0080] The end of the hydraulic rod 103 extending out of the hydraulic cylinder body 102 and the end fastener 106 can be fixedly connected by welding; a sliding gap is left between the cavity wall of the telescopic member 107 and the hydraulic cylinder body 102.

[0081] When the end of the hydraulic rod 103 close to the vehicle door 002 extends out of the hydraulic cylinder body 102, the hydraulic rod 103 pushes the telescopic part 107 to move to the side away from the vehicle body 001. At this time, the hydraulic cylinder body 102 gradually leaks out of the cavity; and when the hydraulic rod 103 contracts, the hydraulic rod 103 pulls the telescopic part 107 to move to the side close to the vehicle body 001. At this time, the hydraulic cylinder body 102 gradually enters the cavity until the hydraulic rod 103 is completely retracted into the hydraulic cylinder body 102.

[0082] Some embodiments of the present disclosure provide a cavity for accommodating the hydraulic cylinder body 102 within the telescopic member 107 to reduce the volume of the door hinge, thereby reducing the space occupied by installing the door hinge and further improving space utilization.

[0083] 3 , 5 and 6 , a connecting flange 111 is provided at one end of the mounting base 101 close to the vehicle body 001 , and the connecting flange 111 is used to connect to the vehicle body 001 , and a guide fillet is provided at the end edge of the telescopic member 107 close to the connecting flange 111 .

[0084] For example, a connecting flange 111 is welded to one end of the mounting base 101 close to the vehicle body 001, and a plurality of bolt holes are evenly arranged on the connecting flange 111 along its own circumference. When installing the door hinge, one end of the bolt is passed through the bolt hole, thereby fixing the mounting base 101 to the vehicle body 001 with the help of the bolt.

[0085] The telescopic member 107 is provided with a guide radius at the end face edge close to the vehicle body 001, thereby forming a transition arc surface at the entrance edge of the spiral guide groove 108, so as to facilitate the rolling body 105 to enter the spiral guide groove 108 and avoid the rolling body 105 from interfering with the spiral guide groove 108 during the process of entering the spiral guide groove 108.

[0086] In some embodiments, referring to FIG. 6 , a connecting plate 112 is provided at one end of the telescopic member 107 extending out of the mounting seat 101 , and a plurality of bolt holes are provided on the connecting plate 112 .

[0087] In some embodiments, referring to Figures 3 and 4, a connecting plate 112 is welded to one end of the telescopic member 107 extending out of the mounting seat 101, and the four corners of the connecting plate 112 protrude radially along the telescopic member 107 to form four protrusions, and a bolt hole is provided on each protrusion; when installing the door hinge, one end of the bolt is passed through the bolt hole and threadedly connected to the door 002, thereby fixing the telescopic member 107 and the door 002.

[0088] Some embodiments of the present disclosure further provide a vehicle door 002 , which includes the above-mentioned door hinge.

[0089] In some embodiments, the door hinge is fixed to the door 002 with bolts, and the door hinge is arranged along the width direction of the vehicle body 001.

[0090] In some embodiments of the present disclosure, the door hinges are arranged along the width direction of the vehicle body 001.
