DETAILED DESCRIPTION

[0033] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can also be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0034] Reference Figure 1-Figure 3 An embodiment of the present invention provides a door hinge, which includes: a mounting seat 101, wherein the mounting seat 101 is used to connect with a vehicle body 001; a telescopic member 107, wherein the telescopic member 107 is movably connected with the mounting seat 101, and an end of the telescopic member 107 away from the vehicle body 001 is used to connect with a vehicle door 002; and a driving component, wherein the driving component is connected with the telescopic member 107 and is used to drive the telescopic member 107 to rotate and reciprocate along the rotation axis direction of the telescopic member 107.

[0035] Specifically, the rotation axis direction of the telescopic member 107 is parallel to the width direction of the vehicle body 001; the mounting seat 101 can be a hollow cylindrical structure, the telescopic member 107 can be a cylindrical rotating shaft structure, the telescopic member 107 is inserted into the hollow cavity of the mounting seat 101, and is movably connected to the mounting seat 101.

[0036] Figure 1 A schematic diagram of a vehicle door hinge in use is specifically shown, where the vehicle door 002 is in a closed state; Figure 1 As shown, the door hinge is arranged between the vehicle body 001 and the vehicle door 002 along the width direction of the vehicle body 001 , and the door hinge is located at the lower left corner of the vehicle door 002 .

[0037] Specifically, the mounting seat 101 can be fixed to the vehicle body 001 by bolts, and one 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 provides power for the telescopic member 107 to rotate and reciprocate along its own rotation axis direction.

[0038] The telescopic member 107 can rotate while reciprocating 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 end of the telescopic member 107 extending out of the mounting seat 101 is fixedly connected to the door 002.

[0039] When the vehicle door 002 is opened, the driving assembly drives the telescopic member 107 to move and rotate along the width direction of the vehicle body 001 toward the side away from the vehicle body 001, so that the vehicle door 002 rotates upward while moving away from the vehicle body 001 until the vehicle door 002 is fully opened.

[0040] When closing the door 002, the driving assembly 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.

[0041] In the embodiment of the present application, the opening and closing of the door 002 is achieved by adopting the above-mentioned door hinge. Compared with the prior art, the present solution arranges 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 the situation where the horizontal space parallel to the door 002 is insufficient.

[0042] Optionally, a guide structure is provided between the mounting seat 101 and the telescopic member 107 , and when the telescopic member 107 reciprocates along the direction of its own rotation axis, the guide structure is used to rotate the telescopic member 107 .

[0043] Specifically, the guide structure can be regarded as a part of the driving assembly. 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.

[0044] In the embodiment of the present application, a guide structure is provided between the mounting seat 101 and the telescopic member 107 so that the driving assembly 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.

[0045] Optionally, 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.

[0046] Specifically, 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 rod can rotate while moving along the width direction of the vehicle body 001, thereby driving the door 002 to close and open.

[0047] 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 rod can rotate while reciprocating along the width direction of the vehicle body 001, thereby driving the door 002 to close and open.

[0048] In addition, the embodiments of the present application do not limit the specific structures of the first guide portion and the second guide portion. Those skilled in the art can flexibly set them according to needs. They only need to make the first guide portion and the second guide portion cooperate with each other so that the telescopic rod can rotate while moving along the width direction of the vehicle body 001.

[0049] Optionally, refer to Figure 3 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.

[0050] Specifically, 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 to drive the door 002 to open or close.

[0051] When the telescopic member 107 reciprocates along the width direction of the vehicle body 001 , the rolling body 105 can rotate freely, thereby reducing the wear and collision between the rolling body 105 and the telescopic member 107 .

[0052] At this time, the driving assembly also includes a driving mechanism, which provides a linear driving force for the telescopic member 107 to move along the width direction of the vehicle body 001. The driving mechanism can be any power element that can provide a linear driving force, such as a hydraulic cylinder, an electric push rod, or a screw lifting mechanism, etc., which is not limited in the embodiment of the present application.

[0053] In addition, the rotation angle of the car 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 rotate 90 degrees at the same time with the help of the spiral guide groove 108 and the rolling body 105, thereby driving the car door 002 to rotate 90 degrees.

[0054] Compared with the prior art, this embodiment reduces the horizontal space parallel to the door 002 occupied by the hinge structure for installing the door hinge by arranging the door hinge between the vehicle body 001 and the door 002 along the width direction of the vehicle body 001, thereby solving the problem in the prior art that the hinge mechanism is not suitable for the situation where there is insufficient space in the horizontal direction parallel to the door 002. Moreover, compared with the complex gear design in the prior art, the door hinge in this solution is guided by rolling elements 105 and spiral guide grooves 108, and its structural design is simple. In addition, during the side opening and rotation of the door 002, there is no vibration and noise caused by the meshing of gear teeth.

[0055] Optionally, refer to Figure 3 and Figure 4 The mounting seat 101 is provided with a mounting hole, and the mounting hole is used to accommodate at least part of the telescopic member 107 . The hole wall of the mounting hole is provided with the rolling body 105 ; the side wall of the telescopic member 107 is provided with the spiral guide groove 108 .

[0056] Specifically, a mounting hole for accommodating the telescopic member 107 is provided on the mounting seat 101 to improve the compactness of the entire hinge structure, and utilize the miniaturized design of the hinge structure to improve space utilization.

[0057] Optionally, refer to Figure 5 and Figure 6 The door hinge further comprises a retainer 104; the retainer 104 is arranged in the mounting hole, the retainer 104 is provided with a through hole 109 for the telescopic member 107 to pass through, and the retainer 104 is used to restrict the rolling body 105 between the telescopic member 107 and the hole wall of the mounting hole. The retainer 104 is provided with a through hole 109 for the rolling body 105 to at least partially embed, and the diameter of the through hole 109 is smaller than the diameter of the rolling body 105. The hole wall of the mounting hole is provided with a rolling groove 110 for the rolling body 105 to at least partially embed, and the rolling groove 110 is provided in a one-to-one correspondence with the through hole 109.

[0058] Specifically, at least one group of retaining frames 104 are arranged inside the mounting seat 101, and a plurality of through holes 109 are evenly arranged on the retaining frames 104 along their own circumference. Each through hole 109 is arranged one-to-one corresponding to 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.

[0059] 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 .

[0060] In this embodiment, 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 restrict 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 is prevented from falling out of the through hole 109 and affecting the subsequent normal operation of the telescopic member 107.

[0061] 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 1 mm to 5 mm 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.

[0062] Optionally, refer to Figure 5 and Figure 6 There are multiple retaining frames 104 , and the multiple retaining frames 104 are arranged at intervals along the rotation axis direction of the telescopic member 107 .

[0063] Specifically, 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.

[0064] 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 .

[0065] Optionally, refer to Figure 3 and Figure 6 The inner diameter of the end of the mounting seat 101 away from the vehicle body 001 is 0.1 mm to 0.5 mm larger than the diameter of the telescopic member 107 .

[0066] Specifically, the inner wall of the mounting seat 101 at one end close to the vehicle door 002 protrudes inward to form a ring, so that the inner diameter of this 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 end of the mounting seat 101 close to 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.

[0067] In this embodiment, the dimension of the inwardly protruding portion of the mounting seat 101 along its own axial direction is 15 mm, and the gap between the protruding portion and the telescopic member 107 is maintained between 0.1 mm and 0.5 mm.

[0068] Optionally, a plurality of spiral guide grooves 108 are provided on the side wall of the telescopic member 107 along its circumference, and each rolling body 105 on the same retaining frame 104 is respectively embedded in different spiral guide grooves 108 .

[0069] Specifically, 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 arranged 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.

[0070] Optionally, refer to Figure 3 and Figure 6 The driving assembly includes: a hydraulic cylinder body 102, which is arranged in the hole of the mounting seat 101; a hydraulic rod 103, which is coaxially arranged with the hydraulic cylinder body 102, and the hydraulic rod 103 is slidably connected to the hydraulic cylinder body 102 along its own axial direction, and the hydraulic rod 103 can rotate around its own axis, and one end of the hydraulic rod 103 extending out of the hydraulic cylinder body 102 is fixedly connected to the telescopic member 107.

[0071] Specifically, the hydraulic cylinder body 102 is coaxially arranged in the mounting seat 101, and a base is welded to one end of the hydraulic cylinder body 102 close to the vehicle body 001. The base is provided with a plurality of bolt holes along its circumference, so that the hydraulic cylinder body 102 can be fixed to the vehicle body 001 by bolts.

[0072] The hydraulic rod 103 is connected to the hydraulic cylinder body 102 in a sliding manner along its own axis, and the hydraulic rod 103 is connected to the hydraulic cylinder body 102 in a rotational manner, so that the hydraulic rod 103 can rotate freely around its own axis. The end of the hydraulic rod 103 extending out of the hydraulic cylinder body 102 is fixedly connected to the telescopic member 107, which can be specifically connected by welding or threading, and the embodiment of the present application does not limit it.

[0073] When the 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 vehicle body 001 toward the side away from the vehicle body 001. At the same time, 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 door 002 is completely opened.

[0074] When closing the door 002, 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 vehicle body 001 toward the side close to the vehicle body 001. At the same time, 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 door 002 is completely closed.

[0075] This embodiment uses a hydraulic cylinder to drive the telescopic member 107 to move. Compared with the prior art, 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.

[0076] Optionally, refer to 3 and Figure 6 The telescopic member 107 is provided with a cavity, and the hydraulic cylinder body 102 is provided in the cavity.

[0077] Specifically, a cavity is coaxially arranged 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.

[0078] 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 a whole by welding, or by a snap-fit ​​structure. The embodiment of the present application does not limit this, and it is only necessary that the end fastener 106 and the telescopic member 107 are fixed as a whole without relative movement.

[0079] 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 cavity in the telescopic member 107 and the hydraulic cylinder body 102.

[0080] 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.

[0081] In this embodiment, a cavity for accommodating the hydraulic cylinder body 102 is provided in 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.

[0082] Optionally, a connecting flange 111 is provided at one end of the mounting seat 101 close to the vehicle body 001 , and the connecting flange 111 is used to connect to the vehicle body 001 . A guide fillet is provided at the end face edge of the telescopic member 107 close to the connecting flange 111 .

[0083] Specifically, 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 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 bolts.

[0084] A guide radius is set on the end face edge of the telescopic member 107 close to the body 001, thereby forming a transition arc surface at the entrance edge of the spiral guide groove 108 to facilitate the rolling body 105 to enter the spiral guide groove 108 and avoid structural interference between the rolling body 105 and the spiral guide groove 108 during the process of entering the spiral guide groove 108.

[0085] Optionally, 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 .

[0086] Specifically, refer to 3 and Figure 4 A connecting plate 112 is welded to one end of the telescopic member 107 extending out of the mounting seat 101. 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.
