DETAILED DESCRIPTION

[0033] Exemplary embodiments of the present application will be described herein below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0034] Reference Figures 1-3 The present embodiment provides a vehicle door hinge, which comprises a mounting base 101 for connecting with a vehicle body 001, a telescopic member 107 movably connected with the mounting base 101, an end of the telescopic member 107 away from the vehicle body 001 for connecting with a vehicle door 002, and a driving assembly connected with the telescopic member 107 for driving 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 base 101 can be a hollow cylindrical structure, and the telescopic member 107 can be a cylindrical rotation shaft structure, which is arranged in the hollow cavity of the mounting base 101 and movably connected with the mounting base 101.

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

[0037] Specifically, the mounting base 101 can be fixed to the vehicle body 001 by bolts, and an end of the telescopic member 107 extending out of the mounting base 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 assembly provides power for the rotation and reciprocation of the telescopic member 107 along the rotation axis direction thereof.

[0038] The telescopic member 107 is capable of rotating while reciprocating along the width direction of the vehicle body 001, so that the mounting base 101 and the telescopic member 107 form a linear hinge structure; the mounting base 101 is arranged between the vehicle body 001 and the vehicle door 002 along the width direction of the vehicle body 001, one end of the mounting base 101 is fixedly connected with the vehicle body 001, and one end of the telescopic member 107 extending out of the mounting base 101 is fixedly connected with the vehicle door 002.

[0039] When the vehicle door 002 is opened, the driving assembly drives the telescopic member 107 to move along the width direction of the vehicle body 001 towards the side away from the vehicle body 001 while rotating, so that the vehicle door 002 rotates upwards while moving towards the side away from the vehicle body 001, until the vehicle door 002 is completely opened.

[0040] When the vehicle door 002 is closed, the driving assembly drives the telescopic member 107 to move along the width direction of the vehicle body 001 towards the side close to the vehicle body 001 while rotating, so that the vehicle door 002 rotates downwards while moving towards the side close to the vehicle body 001, until the vehicle door 002 is completely closed.

[0041] In the embodiment of the present application, the opening and closing of the vehicle door 002 are realized by using the above-mentioned vehicle door hinge. Compared with the prior art, the vehicle door hinge is arranged along the width direction of the vehicle body 001, so that the horizontal space parallel to the vehicle door 002 occupied by the hinge structure is reduced, so as to be applicable to the case where the space arranged in the horizontal direction parallel to the vehicle door 002 is insufficient.

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

[0043] Specifically, the guide structure can be regarded as part of the driving assembly. Under the action of the guide structure, the telescopic member 107 is capable of rotating while moving along the width direction of the vehicle body 001, so as to drive the vehicle door 002 to open and close.

[0044] In the embodiment of the present application, the guide structure is arranged between the mounting base 101 and the telescopic member 107, so that the driving assembly only needs to provide linear driving force for the telescopic member 107 to reciprocate along the width direction of the vehicle body 001, so as to be capable of simplifying the power structure of the driving assembly.

[0045] Optionally, the guide structure comprises a first guide part and a second guide part, the first guide part is connected with the mounting base 101, the second guide part is connected with the telescopic member 107, and the first guide part and the second guide part cooperate with each other.

[0046] Specifically, the first guide part can be a protrusion on the mounting base 101, and the second guide part can be a groove on the telescopic piece 107, the groove and the protrusion being matched with each other to limit the movement direction of the telescopic piece 107, so that the telescopic rod can rotate while moving along the width direction of the vehicle body 001, thereby driving the vehicle door 002 to close and open.

[0047] Correspondingly, the first guide part can also be a groove on the mounting base 101, and the second guide part can be a protrusion on the telescopic piece 107, the groove and the protrusion being matched with each other to limit the movement direction of the telescopic piece 107, so that the telescopic rod can rotate while reciprocating along the width direction of the vehicle body 001, thereby driving the vehicle 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 part and the second guide part, and a person skilled in the art can flexibly set them according to needs, as long as the first guide part and the second guide part are matched with each other, so that the telescopic rod can rotate while moving along the width direction of the vehicle body 001.

[0049] Optionally, referring to Figure 3 , the first guide part is a spiral guide groove 108, and the second guide part is a rolling body 105, the spiral guide groove 108 and the rolling body 105 being matched 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 piece 107, the rolling body 105 being arranged between the telescopic piece 107 and the mounting base 101, the rolling body 105 being in contact with the groove wall of the spiral guide groove 108 to limit the movement direction of the telescopic piece 107, so that the telescopic piece 107 rotates while reciprocating along the width direction of the vehicle body 001, thereby driving the vehicle door 002 to open or close.

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

[0052] At this time, the driving assembly further includes a driving mechanism, which provides a linear driving force for the telescopic piece 107 to move along the width direction of the vehicle body 001. The driving mechanism can be any power element capable of providing a linear driving force, such as a hydraulic cylinder, an electric push rod or a screw jacking mechanism, and the embodiments of the present application do not limit it.

[0053] In addition, the rotation angle of the door 002 can be adjusted by adjusting the parameters of the helical 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 by means of the helical guide groove 108 and the rolling body 105, thereby driving the door 002 to rotate 90 degrees.

[0054] The present embodiment reduces the horizontal space parallel to the door 002 occupied by the installation of the hinge structure, compared with the prior art, thereby solving the problem of insufficient space for the horizontal direction parallel to the door 002 in the prior art. In addition, compared with the complex gear design in the prior art, the door hinge in the present scheme uses the rolling body 105 and the helical guide groove 108 for guidance, which has a simple structure design, and does not have the vibration and noise caused by the meshing of the gear teeth during the rotation of the door 002.

[0055] Optionally, referring to Figure 3 and Figure 4 , the mounting seat 101 is provided with a mounting hole for accommodating at least part of the telescopic member 107, and 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 helical guide groove 108.

[0056] Specifically, a mounting hole for accommodating the telescopic member 107 is arranged on the mounting seat 101 to improve the compactness of the entire hinge structure, and the hinge structure is designed to be small in size, thereby improving the space utilization.

[0057] Optionally, referring to Figure 5 and Figure 6 , the door hinge further comprises a retaining frame 104; the retaining frame 104 is arranged in the mounting hole, and the retaining frame 104 is provided with a through hole 109 through which the telescopic member 107 passes, and the retaining frame 104 is used to limit the rolling body 105 between the telescopic member 107 and the hole wall of the mounting hole. The retaining frame 104 is provided with a through hole 109 for at least partial embedding of the rolling body 105, 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 at least partial embedding of the rolling body 105, and the rolling groove 110 is arranged one-to-one with the through hole 109.

[0058] Specifically, the inside of the mounting seat 101 is provided with at least one set of the retainer 104, the retainer 104 is uniformly provided with a plurality of through holes 109 along the circumference thereof, each of the through holes 109 is provided in one-to-one correspondence with each of the rolling grooves 110, each of the rolling bodies 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 retainer 104 is fixedly connected with the mounting seat 101, and specifically can be connected by welding, so as to fix the position of the retainer 104 and avoid the movement of the retainer 104 when the telescopic part 107 moves, thereby affecting the normal work of the telescopic part 107.

[0060] In the embodiment, the coaxiality between the telescopic part 107 and the mounting seat 101 is improved by the retainer 104, so as to improve the movement stability of the telescopic part 107; the diameter of the through hole 109 on the retainer 104 is smaller than the diameter of the rolling body 105, so as to limit the rolling body 105 in the through hole 109, and when the telescopic part 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 work of the telescopic part 107.

[0061] In addition, in order to reduce the abrasion between the rolling body 105 and the groove wall of the spiral guide groove 108, the cross-sectional diameter of the spiral guide groove 108 is 1mm-5mm larger than the diameter of the rolling body 105, so as to reserve a rolling gap between the rolling body 105 and the groove wall of the spiral guide groove 108.

[0062] Optionally, referring to Figure 5 and Figure 6 , the retainer 104 is a plurality of retainers, and the plurality of retainers 104 are arranged at intervals along the rotation axis direction of the telescopic part 107.

[0063] Specifically, the number of the retainers 104 can be one or a plurality, and by increasing the number of the retainers 104, the movement stability of the telescopic part 107 can be improved.

[0064] In some embodiments, the number of the retainers 104 is a plurality, and the plurality of retainers 104 are arranged at intervals along the rotation axis direction of the telescopic part 107, so as to further improve the movement stability of the telescopic part 107.

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

[0066] Specifically, the inner wall of the mounting seat 101 near one end of the door 002 is protruded inward to form a ring shape, so that the inner diameter of the end is reduced and fits the side wall of the telescopic part 107. When the telescopic part 107 is partially rotated out of the mounting seat 101, the end of the mounting seat 101 near the door 002 can provide support for the telescopic part 107, so as to improve the coaxiality of the telescopic part 107 and the mounting seat 101.

[0067] In the embodiment, the protruding part of the mounting seat 101 has a dimension of 15 mm along the axial direction of the mounting seat 101, and the gap between the protruding part and the telescopic part 107 is kept between 0.1 mm and 0.5 mm.

[0068] Optionally, the side wall of the telescopic part 107 is provided with a plurality of spiral guide grooves 108 along the circumferential direction of the telescopic part 107, and each rolling body 105 on the same retainer 104 is embedded in a different spiral guide groove 108.

[0069] Specifically, the side wall of the telescopic part 107 is provided with a plurality of spiral guide grooves 108, and the plurality of spiral guide grooves 108 are uniformly arranged along the circumferential direction of the telescopic part 107. By increasing the number of spiral guide grooves 108, the movement stability of the telescopic part 107 can be improved.

[0070] Optionally, referring to Figure 3 and Figure 6 , the driving assembly comprises a hydraulic cylinder body 102 arranged in the hole of the mounting seat 101, and a hydraulic rod 103 coaxially arranged with the hydraulic cylinder body 102. The hydraulic rod 103 is slidably connected with the hydraulic cylinder body 102 along the axial direction of the hydraulic rod 103 and the hydraulic cylinder body 102, and the hydraulic rod 103 can rotate around the axial line thereof. One end of the hydraulic rod 103 extending out of the hydraulic cylinder body 102 is fixedly connected with the telescopic part 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 near the vehicle body 001. A plurality of bolt holes are arranged on the base along the circumferential direction of the base, so that the hydraulic cylinder body 102 can be fixed to the vehicle body 001 by means of bolts.

[0072] The hydraulic rod 103 is slidably connected with the hydraulic cylinder body 102 along the axial direction of the hydraulic rod 103 and the hydraulic cylinder body 102, and the hydraulic rod 103 is rotationally connected with the hydraulic cylinder body 102, so that the hydraulic rod 103 can rotate freely around the axial line thereof. The end of the hydraulic rod 103 extending out of the hydraulic cylinder body 102 is fixedly connected with the telescopic part 107, which can be achieved by welding or threaded connection, and the present application does not limit the connection mode.

[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 towards the side away from the vehicle body 001, and 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 the 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 vehicle body 001 towards the side close to the vehicle body 001, and 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] Compared with the prior art, the embodiment drives the telescopic member 107 to move by using a hydraulic cylinder, and the door 002 can be stably stopped at any position during opening and closing of the door 002, and the process control precision is high.

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

[0077] Specifically, the telescopic member 107 is coaxially provided with a cavity, and when the door 002 is in a completely closed state, the hydraulic cylinder 102 is mostly arranged in the cavity.

[0078] An end fastener 106 is arranged at one end of the telescopic member 107 close to the door 002, the end fastener 106 seals the end opening of the telescopic member 107, and the end fastener 106 and the telescopic member 107 can be fixed as a whole by welding or can be fixed as a whole by a buckle structure, which is not limited in the embodiment of the application, as long as the end fastener 106 and the telescopic member 107 are fixed as a whole and do not move relative to each other.

[0079] The end of the hydraulic cylinder 102 where the hydraulic rod 103 extends out and the end fastener 106 can be fixedly connected by welding; and a sliding gap is left between the cavity wall of the cavity in the telescopic member 107 and the hydraulic cylinder 102.

[0080] When the end of the hydraulic rod 103 close to the door 002 extends out of the hydraulic cylinder 102, the hydraulic rod 103 pushes the telescopic member 107 to move towards the side away from the vehicle body 001, at this time, the hydraulic cylinder 102 gradually leaks out of the cavity; and when the hydraulic rod 103 retracts, the hydraulic rod 103 pulls the telescopic member 107 to move towards the side close to the vehicle body 001, at this time, the hydraulic cylinder 102 gradually enters the cavity until the hydraulic rod 103 is completely retracted into the hydraulic cylinder 102.

[0081] This embodiment reduces the size of the door hinge by providing a cavity within the telescopic member 107 to accommodate the hydraulic cylinder 102, thereby reducing the space occupied by the door hinge and further improving space utilization.

[0082] Optionally, the mounting base 101 is provided with a connecting flange 111 at one end near the vehicle body 001. The connecting flange 111 is used to connect with the vehicle body 001, and the telescopic member 107 is provided with a guide radius at the edge of the end face near the connecting flange 111.

[0083] Specifically, a connecting flange 111 is welded to one end of the mounting base 101 near the vehicle body 001. Multiple 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 bolt.

[0084] The telescopic component 107 has a guide fillet on the end face edge near the vehicle body 001, thereby forming a transition arc surface at the entrance edge of the spiral guide groove 108, so that the rolling element 105 can enter the spiral guide groove 108 and avoid structural interference between the rolling element 105 and the spiral guide groove 108 during the process of entering the spiral guide groove 108.

[0085] Optionally, the end of the telescopic member 107 extending out of the mounting base 101 is provided with a connecting plate 112, and the connecting plate 112 is provided with a plurality of bolt holes.

[0086] Specifically, refer to 3 and Figure 4 A connecting plate 112 is welded to one end of the telescopic member 107 that extends out of the mounting base 101. The four corners of the connecting plate 112 protrude radially along the telescopic member 107 to form four protrusions, and each protrusion is provided with a bolt hole. When installing the door hinge, one end of the bolt is passed through the bolt hole and threaded to the door 002, thereby fixing the telescopic member 107 and the door 002 together.

[0087] This invention also provides a car door 002, which includes the aforementioned car door hinge.

[0088] Specifically, the door hinges are bolted to the door 002, and the door hinges are set along the width direction of the body 001.

[0089] In this embodiment, the door hinges are arranged along the width direction of the vehicle body 001. Compared with the prior art, this reduces the horizontal space parallel to the door 002 occupied by the hinge structure, thereby freeing up space for installing other components inside the door 002. This solves the problem that the existing hinge mechanism is not suitable for situations where there is insufficient space in the horizontal direction parallel to the door 002.
