[0039] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0041] Example 1

[0042] Reference Figures 1 to 4 As shown, this embodiment provides a vehicle door opening and closing structure 1 , comprising a guide rail 11 , a bracket 12 and a vehicle door mounting member 13 .

[0043] The guide rail 11 is provided on the vehicle, and extends along the longitudinal direction of the vehicle.

[0044] A bracket 12 is slidably mounted on the guide rail 11. A door mounting member 13 is rotatably mounted on the bracket 12 and is configured to connect to the vehicle door 3. When the door mounting member 13 rotates relative to the bracket 12 about the height of the vehicle, the door mounting member 13 drives the door 3 to open and close in a first position. When the door mounting member 13 rotates relative to the bracket 12 about the width of the vehicle, the door mounting member 13 drives the door 3 to open and close in a second position. When the bracket 12 slides along the guide rail 11, the door mounting member 13 slides along the length of the vehicle, thereby coordinating the door 3 to open and close in a third position.

[0045] In a specific implementation, the guide rail 11 can be set on the side outer panel 2 of the vehicle door 3 and extend along the length direction of the vehicle. The length direction of the vehicle can be referred to as the x direction shown in Figure 1. Among them, the bracket 12 is slidably set on the guide rail 11, so that the bracket 12 can slide back and forth along the length direction of the guide rail 11. The vehicle door mounting member 13 is rotatably set on the bracket 12 and the vehicle door mounting member 13 is connected to the vehicle door 3, so that the door mounting member 13 can be relative to the bracket 12 with the vehicle height direction as the axis (for details, please refer to Figure 1 The specific rotation direction is shown in the z direction. Figure 5 As shown by the arrow, the door mounting member 13 can drive the door 3 to move as shown in FIG. Figure 5 When the door mounting member 13 is relative to the bracket 12 with the width direction of the vehicle as the axis (refer to Figure 1 When rotating in the y direction, the specific rotation direction is as shown in Figure 7 As shown by the arrow, the door mounting member 13 can drive the door 3 to move as shown in FIG. Figure 7When the bracket 12 slides relative to the guide rail 11 along the length of the vehicle, the bracket 12 can drive the door mounting member 13 to slide along the length of the vehicle. Figure 6 The direction of the arrow shown in FIG. 1 drives the door 3 connected to the door mounting member 13 to slide along the length direction of the vehicle, thereby realizing the sliding opening and closing of the door. For details, please refer to FIG. Figure 6 shown.

[0046] That is, the first posture is as follows Figure 5 The second posture is as shown in FIG. Figure 7 The third posture is as shown in FIG. Figure 6 The sliding opening and closing posture is shown.

[0047] In summary, this embodiment enables the bracket 12 to slide along the length direction of the vehicle relative to the guide rail 11, or the door mounting member 13 to rotate relative to the bracket 12 around the height direction of the vehicle as the axis, or around the width direction of the vehicle as the axis, so as to realize the sliding opening and closing, or rotating opening and closing, or rotor opening and closing of the door 3, thereby allowing the same vehicle to adopt different opening methods to open and close the door 3 according to actual needs, and then different opening methods can be selected according to the usage scenario to improve applicability.

[0048] In addition, a motor can be additionally provided on the vehicle to drive the bracket 12 to slide relative to the guide rail 11, a motor to drive the door mounting member 13 to rotate around the height direction of the vehicle as an axis, and a motor to drive the door mounting member 13 to rotate around the width direction of the vehicle as an axis. These three motors can work independently of each other to enable the door 3 to be opened and closed in different postures.

[0049] In a specific implementation, the guide rail 11 can be secured to the vehicle's side outer panel 2 using first fasteners 8 such as bolts. For example, both the vehicle's side outer panel 2 and the guide rail 11 may be provided with connection holes, through which first fasteners 8 such as bolts are inserted to secure the guide rail 11 to the vehicle's side outer panel 2. Alternatively, the guide rail 11 may be secured to the vehicle's side outer panel 2 by welding or clamping.

[0050] Furthermore, the door mounting member 13 and the door 3 may also be connected using a second fastener 9, such as a bolt. For example, mounting holes may be provided on both the door mounting member 13 and the door 3, with the second fastener 9, such as a bolt, inserted through the mounting holes to connect the door mounting member 13 and the door 3. Alternatively, the door mounting member 13 and the door 3 may be connected using welding or a clamping method. Furthermore, at least two mounting holes may be provided, thereby further enhancing the stability of the connection between the door mounting member 13 and the door 3 through the combination of the at least two mounting holes and the bolts.

[0051] The vehicle door opening and closing structure 1 provided in this embodiment includes a guide rail 11, a bracket 12, and a door mounting member 13. The guide rail 11 is provided on the vehicle and extends along the length direction of the vehicle. The bracket 12 is slidably provided on the guide rail 11, and the door mounting member 13 is rotatably provided on the bracket 12 and is used to connect with the vehicle door 3 of the vehicle, so that when the door mounting member 13 rotates relative to the bracket 12 with the height direction of the vehicle as the axis, the door mounting member 13 drives the vehicle door 3 to open and close in a first posture. When the door mounting member 13 rotates relative to the bracket 12 with the width direction of the vehicle as the axis, the door mounting member 13 drives the vehicle door 3 to open and close in a second posture. When the bracket 12 slides along the guide rail 11, it drives the door mounting member 13 to slide along the length direction of the vehicle and links the vehicle door 3 to open and close in a third posture. That is to say, by designing a door opening and closing structure 1 connected to the vehicle and the door 3 respectively, and by setting the door opening and closing structure 1 to include a guide rail 11, a bracket 12 and a door mounting member 13, the bracket 12 can slide relative to the guide rail 11 along the length direction of the vehicle, and the door mounting member 13 can rotate relative to the bracket 12 with the height direction of the vehicle as the axis or with the width direction of the vehicle as the axis, so that the door 3 can be opened in different postures, that is, the door 3 can be opened and closed in different ways, and then can be applied to different usage scenarios to improve applicability.

[0052] Reference Figure 1 and Figure 2 As shown, in some embodiments, a first rotating structure 4 is provided between the door mounting member 13 and the bracket 12, and the door mounting member 13 is rotatably connected to the bracket 12 via the first rotating structure 4, and the axial direction of the rotating axis of the first rotating structure 4 is parallel to the height direction of the vehicle, so that the door mounting member 13 can rotate relative to the bracket 12 around the height direction of the vehicle, so that the door 3 can be rotated as shown in FIG. Figure 5 Open and close in the rotating opening and closing manner shown.

[0053] For example, when the door mounting member 13 rotates clockwise relative to the bracket 12 around the vehicle height direction as the axis, the door 3 can be opened. When the door mounting member 13 rotates counterclockwise relative to the bracket 12 around the vehicle height direction as the axis, the door 3 can be closed.

[0054] Reference Figure 1 and Figure 2As shown, in a specific implementation, the first rotating structure 4 includes a rotating sleeve 41, a first rotating shaft and a first rotating cylinder 42. The rotating sleeve 41 is arranged on the bracket 12, the first rotating cylinder 42 is connected to the vehicle door mounting member 13, the first rotating shaft is respectively passed through the rotating sleeve 41 and the first rotating cylinder 42, and the first rotating shaft is rotatably connected to the rotating sleeve 41 and the first rotating cylinder 42 respectively; the axial direction of the first rotating shaft is parallel to the height direction of the vehicle.

[0055] That is, the rotating sleeve 41 is provided on the bracket 12 and is relatively fixed to the bracket 12, the first rotating cylinder 42 is provided on the door mounting member 13 and is relatively fixed to the door mounting member 13, the first rotating shaft is respectively provided in the first rotating cylinder 42 and the rotating sleeve 41 and is respectively rotated with the first rotating cylinder 42 and the rotating sleeve 41, and the axial direction of the first rotating shaft is as follows: Figure 1 The z direction shown in FIG. 1 , so that the door mounting member 13 can be rotated relative to the bracket 12 around the height direction of the vehicle (refer to FIG. Figure 1 The door 3 can be rotated in the following directions: Figure 5 Open and close in the direction of rotation shown.

[0056] Specifically, two rotating sleeves 41 can be provided, and the first rotating cylinder 42 can be located between the two rotating sleeves 41 and coaxially arranged, so that the first rotating shaft passes through the rotating sleeve 41 and the first rotating cylinder 42. For example, the rotating sleeve 41 can be integrally formed with the bracket 12 or formed separately and then welded together, and the first rotating cylinder 42 can be integrally formed with the vehicle door mounting member 13 or formed separately and then welded together.

[0057] In addition, it has been found through testing that in this embodiment, when the door 3 and the vehicle are connected via the door opening and closing structure 1, when the door 3 is opened by screwing, the maximum opening angle of the door 3 can reach 92°.

[0058] Reference Figure 1 and Figure 2 As shown, in some embodiments, a second rotating structure 5 is provided between the door mounting member 13 and the bracket 12, and the door mounting member 13 is rotatably connected to the bracket 12 via the second rotating structure 5. When the door 3 is in the open state, the axial direction of the rotating axis of the second rotating structure 5 is parallel to the width direction of the vehicle, so that the door mounting member 13 can rotate relative to the bracket 12 around the width direction of the vehicle, so that the door 3 can be rotated as shown in FIG. Figure 7 The rotor is opened and closed in the manner shown.

[0059] For example, when the door mounting member 13 rotates clockwise relative to the bracket 12 around the width direction of the vehicle as an axis, the door 3 can be opened. When the door mounting member 13 rotates counterclockwise relative to the bracket 12 around the width direction of the vehicle as an axis, the door 3 can be closed.

[0060] Reference Figure 1 and Figure 2 As shown, in specific implementation, in some embodiments, the second rotating structure 5 includes a second rotating shaft and a second rotating drum 51 which is sleeved outside the second rotating shaft and rotatably connected to the second rotating shaft; one of the second rotating shaft and the second rotating drum 51 is set on the bracket 12, and the other of the second rotating shaft and the second rotating drum 51 is set on the vehicle door mounting member 13; when the vehicle door 3 is in an open state, the axial direction of the second rotating shaft is parallel to the width direction of the vehicle.

[0061] That is to say, the second rotating shaft is arranged in the second rotating drum 51 and rotates with the second rotating drum 51. One of the second rotating shaft and the second rotating drum 51 is connected to the bracket 12, and the other is connected to the door mounting member 13. When the door 3 is in the open state, the axial direction of the second rotating shaft is as follows: Figure 1 The y direction shown in FIG. 1 , so that the door mounting member 13 can be relative to the bracket 12 around the width direction of the vehicle (refer to FIG. Figure 1 The door 3 can be rotated in the following directions: Figure 7 The rotor is opened and closed in the manner shown.

[0062] Reference Figure 2 and Figure 3 As shown, in some embodiments, the guide rail 11 is provided with a first transmission portion extending along the length direction of the guide rail 11, and a second transmission portion is provided on the bracket 12 at a position corresponding to the first transmission portion and cooperating with the first transmission portion. The bracket 12 slides back and forth along the length direction of the guide rail 11 relative to the guide rail 11 through the cooperation of the first transmission portion and the second transmission portion, so that when the bracket 12 slides relative to the guide rail 11 along the length direction of the vehicle, it can drive the door mounting member 13 to slide along the length direction of the vehicle, and then drive the door 3 to be moved as shown in FIG. Figure 6 The sliding opening and closing method is used for opening and closing.

[0063] For example, when the bracket 12 slides relative to the guide rail 11 in a direction close to the front of the vehicle, the door 3 can be driven to open. When the bracket 12 slides relative to the guide rail 11 in a direction away from the front of the vehicle, the door 3 can be driven to close.

[0064] Reference Figure 2 and Figure 3As shown, in some embodiments, the first transmission part includes a rack 6, and the second transmission part includes a gear 7 meshing with the rack 6. The bracket 12 reciprocates relative to the guide rail 11 along the length direction of the guide rail 11 through the meshing of the rack 6 and the gear 7, so that the bracket 12 can slide relative to the guide rail 11 along the length direction of the vehicle under the meshing of the rack 6 and the gear 7, and can drive the door mounting member 13 to slide along the length direction of the vehicle, and then drive the door 3 to be as shown. Figure 6 The sliding opening and closing method is used for opening and closing.

[0065] Furthermore, the cooperation between the gear 7 and the rack 6 allows the sliding travel of the bracket 12 relative to the guide rail 11 to be precisely controlled and limited, thereby allowing the door 3 to slide open to any desired position. For example, a drive motor can be provided to rotate the gear 7, thereby meshing the gear 7 with the rack 6 and driving the bracket 12 to slide back and forth relative to the guide rail 11 along the length of the vehicle.

[0066] In specific implementation, in order to make the sliding of the bracket 12 relative to the guide rail 11 smoother, two racks 6 can be set, and the two racks 6 are arranged at intervals along the height direction of the vehicle, and there are at least two gears 7, and at least two gears 7 are arranged on both sides of the rack 6 along the height direction of the vehicle, so that the bracket 12 can be smoothly moved relative to the guide rail 11 by cooperating with at least two gears 7 and at least two racks 6.

[0067] For example, a rack 6 may be provided on the bracket 12 and a gear 7 may be provided on the guide rail 11. Figure 3 As shown, a rotatably matched gear 7 can be provided on the bracket 12 , and a rack 6 fixed relative to the guide rail 11 can be provided on the guide rail 11 .

[0068] Reference Figure 3 As shown, in some embodiments, a first guide portion is provided on the bracket 12, and a second guide portion is provided on the guide rail 11 at a position corresponding to the first guide portion. The bracket 12 slides along the guide rail 11 through the guiding cooperation between the first guide portion and the second guide portion to ensure that the bracket 12 can move reliably and smoothly along the length direction of the vehicle without being offset or skewed to affect the normal opening and closing of the door 3.

[0069] In a specific implementation, one of the first guide portion and the second guide portion is a guide groove 111, and the other of the first guide portion and the second guide portion is a guide wheel 121 that can slide along the guide groove 111. The guide groove 111 extends along the length direction of the vehicle, so that the guide wheel 121 slides in the guide groove 111, and then guides and limits the movement process of the bracket 12 relative to the guide rail 11.

[0070] For example, refer to Figure 3 As shown, a guide groove 111 extending along the length direction of the vehicle can be provided on the guide rail 11, and a guide wheel 121 can be provided on the bracket 12. Alternatively, a guide wheel 121 can be provided on the guide rail 11 and a guide groove 111 can be provided on the bracket 12.

[0071] In order to further enhance the guiding effect on the bracket 12, in this embodiment, at least two first guide portions can be provided, and at least two first guide portions are provided on the bracket 12 along the height direction of the vehicle, and at least two second guide portions are provided, and the second guide portions correspond one-to-one to the first guide portions, so that the guiding accuracy of the bracket 12 can be enhanced through the cooperation of at least two first guide portions and at least two second guide portions.

[0072] Reference Figures 1 to 4 As shown, in some embodiments, the bracket 12 includes a bracket body 122 and a telescopic structure 123. The bracket body 122 is slidably disposed on the guide rail 11, and the telescopic structure 123 is respectively connected to the bracket body 122 and the door mounting member 13. The telescopic structure 123 can be extended and retracted along the width direction of the vehicle to move the door 3 along the width direction of the vehicle in conjunction with the door mounting member 13.

[0073] In specific implementation, in order to prevent the car door 3 from being affected or interfered by the car door 3 window frame and to allow the car door 3 to open to a larger angle, when the car door 3 is opened by sliding the car door mounting part 13 through the bracket 12, or the car door mounting part 13 is rotated relative to the bracket 12 to realize the car door 3 to be screwed open or the rotary wing to be opened, the telescopic structure 123 can be extended first, thereby driving the car door mounting part 13 to move outward a certain distance, so that the car door 3 window frame will not affect the normal opening of the car door 3, and then the car door 3 can be opened by sliding, rotating or screwing.

[0074] Accordingly, when closing the door 3, no matter whether the door 3 is closed by sliding, rotating or screwing, in order to ensure a zero-order difference between the door 3 and the window frame of the door 3, the telescopic structure 123 can be retracted to drive the door mounting part 13 to move a certain distance toward the inside of the vehicle, thereby ensuring that the door 3 is closed in place.

[0075] Exemplarily, the telescopic structure 123 may specifically include a telescopic cylinder 124 and a telescopic block 125 . The telescopic cylinder 124 may be connected to the bracket 12 and the telescopic block 125 respectively. The telescopic block 125 may be rotatably connected to the door mounting member 13 .
