[0028] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.
[0029] The utility model provides a vehicle door hinge with a variable inclination angle, comprising:
[0030] The hinge plate of the vehicle body is provided with an adjustment slot along the Z direction;
[0031] The body hinge adjustment plate has one end movably arranged in the adjustment groove through a connecting pin shaft, the connecting pin shaft is arranged along the X direction, and the body hinge adjustment plate can be driven by the connecting pin shaft to move circumferentially in the adjustment groove around the axis direction of the connecting pin shaft, and the other end of the body hinge adjustment plate is connected to the door hinge plate;
[0032] The electric control component is drivingly connected to the connecting pin shaft.
[0033] Specifically, the door hinge is installed on the vehicle body through a vehicle body hinge plate, and an adjustment groove is arranged on the side of the vehicle body hinge plate away from the vehicle body, the adjustment groove is arranged along the Z direction of the vehicle, and the vehicle body hinge adjustment plate is arranged in the adjustment groove through a connecting pin shaft. Since the connecting pin shaft passes through the adjustment groove along the X direction, the vehicle body hinge adjustment plate can be circumferentially adjusted along the axis of the connecting pin shaft in the adjustment groove. When the electronic control component drives the connecting pin shaft to rotate, the angle between the vehicle body hinge adjustment plate and the adjustment groove changes, so that the vehicle body hinge adjustment plate can drive the door hinge plate to rotate, thereby realizing the change of the inclination angle between the vehicle door and the door hinge mounting surface, controlling the self-closing tendency and closing energy of the door, and improving the user's experience of opening and closing the door.
[0034] Optionally, the vehicle body hinge plate is L-shaped, a bolt fixing hole is provided on a long side of the vehicle body hinge plate, and an adjustment groove is provided on an end face of a short side of the vehicle body hinge plate.
[0035] Specifically, the long side of the body hinge plate is in contact with the body, and the door hinge is fixed to the side of the body through a bolt fixing hole. The short side of the body hinge plate is extended along the Y direction of the car, and the adjustment groove is arranged on the Y surface of the short side of the body hinge plate. In this way, when the body hinge adjustment plate is inserted into the adjustment groove, the connecting pin shaft can maintain a perpendicular relationship with the body hinge adjustment plate; in this way, when the rotation angle of the connecting pin shaft is adjusted, the inclination angle of the body hinge adjustment plate can be driven to change.
[0036] Optionally, a pin shaft hole is correspondingly opened on the groove wall of the adjustment groove, the end of the connecting pin shaft passes through the pin shaft hole in sequence and is connected to the electronic control component, and the body hinge adjustment plate is connected to the middle part of the connecting pin shaft.
[0037] Specifically, pin holes are correspondingly opened on the two groove walls of the adjustment groove along the X direction of the car. One end of the body hinge adjustment plate is inserted into the adjustment groove and is located between the two pin holes. The connecting pin passes through the pin hole and one end of the body hinge adjustment plate and is connected to the electronic control component. In this way, the electronic control component can change the angular position of the body hinge adjustment plate in the adjustment groove by driving the connecting pin to rotate. In this way, the angle formed by the door hinge plate connected to the body hinge adjustment plate and the plane where the long side of the body hinge plate is located is also changed, and finally the change in the inclination angle of the door is experienced.
[0038] Optionally, the height of the adjustment groove along the Z direction is greater than the height of the vehicle body hinge adjustment plate, and the pin shaft hole is centrally arranged on the groove wall of the adjustment groove.
[0039] Optionally, the vehicle body hinge adjustment plate has an adjustment range of -1° to 1° in the adjustment slot.
[0040] Specifically, the height of the vehicle body hinge adjustment plate is smaller than the height of the adjustment slot. When the vehicle body hinge adjustment plate is fixed in the adjustment slot by the connecting pin, the connecting pin in the initial state sets the vehicle body hinge adjustment plate in a horizontal direction, so that the vehicle body hinge adjustment plate can be adjusted clockwise or counterclockwise by the connecting pin to meet the adjustment of the inward inclination angle of the door in different directions; the adjustable angle between the door and the vehicle body is controlled within a small range, for example, the height of the adjustment slot is greater than the height of the vehicle body hinge adjustment plate to meet the distance that can be rotated 1°, so that the general door adjustment range can be met, ensuring the improvement of the door closing speed, self-closing trend and closing sound quality, and when the vehicle body hinge adjustment plate is installed, the door hinge will not have excessive angle deviation, affecting the door installation.
[0041] Optionally, a spline hole is provided on the vehicle body hinge adjustment plate, and the connecting pin shaft is plug-fitted into the spline hole.
[0042] Optionally, the electric control component is a rotary motor, which is arranged on a hinge plate of the vehicle body, and an output end of the rotary motor is connected to a connecting pin shaft.
[0043] Specifically, the rotating motor is arranged on the outside of the adjustment slot. When the inclination angle of the door needs to be adjusted, the rotating motor drives the connecting pin shaft to rotate. Since the connecting pin shaft and the body hinge adjustment plate are connected by a spline, this can drive the body hinge adjustment plate to rotate, and can monitor the rotation angle of the inclination angle, so as to grasp the positional relationship between the door and the body.
[0044] Optionally, the vehicle body hinge adjustment plate is provided with a clamping portion along the circumferential direction, and the clamping portion matches with a notch of the adjustment slot.
[0045] Specifically, the approximate length of the vehicle body hinge adjustment plate inserted into the adjustment slot can be controlled by the clamping portion. When the clamping portion is about to fit into the notch of the adjustment slot, the installation position of the vehicle body hinge adjustment plate can be confirmed based on the positional relationship between the spline hole and the pin shaft hole, and finally the connecting pin shaft can be installed in place.
[0046] The utility model also provides a vehicle door assembly, comprising the vehicle door hinge with variable inclination angle.
[0047] Specifically, the variable inclination angle door hinge is applied to the door assembly, and the original single-part door steel hinge, which cannot adjust the inclination angle, is split into a body hinge plate and a body hinge adjustment plate. By connecting the pin shaft and driven by the electronic control component, the rotation angle of the body hinge adjustment plate in the adjustment groove can be adjusted. This can change the positional relationship between the door and the lock body or the sealing strip, and control the self-closing tendency and closing ability of the door, thereby reducing the cost of design changes and actual vehicle verification costs.
[0048] The utility model also provides a car, comprising the above-mentioned door assembly.
