Description

Technical Field

[0001] The present invention relates to the technical field of automotive door accessories, and particularly to an opening angle adjusting mechanism and an automobile. Background Art

[0002] As a means of transportation, automobiles have brought great convenience to people's lives and work since their inception. According to different vehicle models, the opening and closing methods of automobile doors mainly include side opening, flat opening, scissor opening, etc. Side-opening doors are mainly applied to models such as MPVs and large SUVs, and are more suitable for use environments with narrow spaces to prevent the door or pedestrians from being damaged by collisions.

[0003] Currently, most side-opening doors on the market mainly move in a way of side-opening along a track or opening parallel to the front of the automobile. When there are obstacles within the door travel range, the door cannot be opened normally. For example, when the tires are fully turned, part of the tires will protrude towards the side of the automobile body. When the side-opening door is fully opened, it will collide with the wheels, affecting the normal opening of the door. However, if the tire is considered for avoidance at this time, the opening travel of the door needs to be reduced, which will in turn cause the space for passengers to get on and off the vehicle to become smaller, affecting the comfort and experience. Summary of the Invention

[0004] Based on this, it is necessary to provide an opening angle adjusting mechanism and an automobile, aiming to solve the problems in the prior art that when the door is opened sideways, it is easily interfered by obstacles and cannot be opened normally, and the opening travel is limited, affecting the comfort and experience of passengers getting on and off the vehicle.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following detailed description of the specific embodiments of the present invention will be provided in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0026] As Figure 1 and Figure 2 shown, an embodiment of the present application provides a structural schematic diagram (partial schematic diagram) of an automobile, which specifically shows a vehicle body 200, a door 300, and a door opening angle adjustment mechanism 100. The door opening angle adjustment mechanism 100 is used to connect the vehicle body 200 and the door 300, and enable the door 300 to open or close relative to the vehicle body 200.

[0027] It can be understood that the vehicle body 200 is provided with an inlet and outlet, and the shape and size of the door 300 respectively match the shape and size of the inlet and outlet one by one. When the door 300 covers the inlet and outlet, the door 300 is in the closed state, and when the door 300 opens the inlet and outlet, the door 300 is in the open state.

[0028] In this embodiment, the door opening angle adjustment mechanism 100 includes: a rotary support assembly 10 and an angle adjustment assembly 20. The first end of the rotary support assembly 10 is used for rotatably connecting with the vehicle body 200, and the second end of the rotary support assembly 10 is used for rotatably connecting with the door 300; the first end of the angle adjustment assembly 20 is rotatably connected with the vehicle body 200, and the second end of the angle adjustment assembly 20 is used for rotatably connecting with the door 300; wherein, the angle adjustment assembly 20 is configured to be adjustable in length, so that the angle adjustment assembly 20 can adjust the opening angle of the door 300.

[0029] In summary, implementing the technical solution of this embodiment will have the following beneficial effects: In the above solution, when the user pulls the door 300 from the outside of the vehicle or pushes the door 300 from the inside of the vehicle, under the connection and support of the rotary support assembly 10, the door 300 will slide and translate relative to the vehicle body 200 to open; however, when there is an obstacle 400 (such as a wheel in the full-lock state) within the opening stroke of the door 300, the angle adjustment assembly 20 can adjust its own length to drive the door 300 to rotate and form an inclined posture relative to the vehicle body 200. In this way, the door 300 can avoid the obstacle 400, prevent the door 300 from being blocked and interfered by the obstacle 400, ensure the normal and smooth opening of the door 300, and at the same time, the opening stroke of the door 300 can also be prevented from being limited, which helps to ensure the comfort and experience of the driver and passengers getting on and off the vehicle.

[0030] Please continue to refer toFigure 2 In order to facilitate understanding of the technical solution, in the above embodiment, it is assumed that the vehicle door 300 has a first side end 310 and a second side end 320 relative to each other. It can be understood that the first side end 310 and the second side end 320 are opposite ends of the vehicle door 300 in the length direction of the vehicle body 200 and the width direction of the vehicle door 300. The rotating support assembly 10 is connected to the middle part of the vehicle door 300, and the angle adjustment assembly 20 is connected to the first side end 310 of the vehicle door 300 to drive the vehicle door 300 to rotate and adjust the tilt angle so that the second side end 320 of the vehicle door 300 avoids the obstacle 400; wherein, a sensor is provided on the vehicle door 300, and the sensor is used to sense the obstacle 400. Optionally, the sensor can be any one of a laser sensor, an infrared sensor, etc.

[0031] When the door 300 slides open, it gradually approaches the obstacle 400. When the sensor detects that the distance between the door 300 and the obstacle 400 is within a preset range, it immediately feeds back a signal to the central controller. The central controller outputs a command to the angle adjustment component 20. The angle adjustment component 20 acts to shorten its own length. The angle adjustment component 20 pulls the first end of the door 300, forcing the door 300 to rotate with the rotating support component 10 as the rotation center. At this time, the second end of the door 300 gradually changes from a posture parallel to the vehicle body 200 to a tilted posture away from the vehicle body 200. Finally, the second end of the door 300 tilts and tilts toward the outside away from the vehicle body 200, thereby avoiding and staying away from the obstacle 400 (such as a fully turned wheel), ensuring that the door 300 opens normally and has sufficient opening stroke.

[0032] Please continue reading Figure 1 and Figure 2 In some embodiments, the angle adjustment assembly 20 includes a telescopic driving unit, and the telescopic driving unit includes a driving member 21 and a telescopic member 22. The driving member 21 is drivingly connected to the telescopic member 22 so that the telescopic member 22 can be retracted or extended relative to the driving member 21. When the driving member 21 drives the telescopic member 22 to retract relative to the driving member 21, the length of the telescopic driving unit becomes shorter, which pulls the door 300, thereby causing the door 300 to rotate and change to a tilted posture, thereby achieving the effect of avoiding the obstacle 400. The structure is simple, the action is fast, and the door 300 is driven reliably.

[0033] Optionally, the telescopic drive unit is configured as any one of an electric push rod, a pneumatic cylinder, an oil cylinder, and a linear motor. For example, in this embodiment, the angle adjustment component 20 uses an electric push rod. The electric push rod is easy to obtain, easy to install, use and maintain, and has low cost.

[0034] It should be noted that when the obstacle is in different positions, by adjusting the length of the telescopic driving unit, the door can be in different inclined angle postures to meet the obstacle avoidance requirements under various working conditions.

[0035] In addition, based on any of the above embodiments, the angle adjustment assembly 20 further includes a first rotating connection seat 23, and one end of the driving member 21 away from the telescopic member 22 is rotatably arranged on the vehicle door 300 or the vehicle body 200 through the first rotating connection seat 23. Further, the angle adjustment assembly 20 further includes a second rotating connection seat 24, and one end of the telescopic member 22 away from the driving member 21 is rotatably arranged on the vehicle door 300 or the vehicle body 200 through the second rotating connection seat 24.

[0036] The first rotating connection seat 23 and the second rotating connection seat 24 provide the rotational degrees of freedom required for the rotation of the vehicle door 300, so that the vehicle door 300 can be frequently switched between the opened and closed states, and can meet the movement requirements of the vehicle door 300 for side-sliding opening and rotational angle adjustment.

[0037] For example, the first rotating connection seat 23 and the second rotating connection seat 24 can be any one of a hinge, a hinge shaft assembly, etc., and can be specifically selected according to actual needs.

[0038] In this embodiment, the first rotating connection seat 23 is assembled and connected to the vehicle body 200, and the second rotating connection seat 24 is assembled and connected to the vehicle door 300. The connection method can be but is not limited to any one of screw connection, snap connection, welding, riveting, bonding, etc., and can be specifically selected according to actual needs.

[0039] Please continue to refer to Figure 1 , in some embodiments, the rotary support assembly 10 includes a rotary support arm 11, a first rotary connection seat 12, and a second rotary connection seat 13. The first end of the rotary support arm 11 is rotatably arranged on the vehicle body 200 through the first rotary connection seat 12, and the second end of the rotary support arm 11 is rotatably arranged on the vehicle door 300 through the second rotary connection seat 13. The rotary support arm 11 realizes the rotational connection between the vehicle door 300 and the vehicle body 200 and ensures the connection strength. The first rotary connection seat 12 and the second rotary connection seat 13 provide the rotational degrees of freedom required for the vehicle door 300 to rotate relative to the vehicle body 200 to open or close.

[0040] For example, the first rotary connection seat 12 and the second rotary connection seat 13 can be any one of a hinge, a hinge shaft assembly, etc., and can be specifically selected according to actual needs.

[0041] In this embodiment, the first rotary connecting seat 12 is assembled and connected to the vehicle body 200, and the second rotary connecting seat 13 is assembled and connected to the vehicle door 300. The connection method can be, but is not limited to, any one of screw connection, snap connection, welding, riveting, bonding, etc., and can be specifically selected according to actual needs.

[0042] Further, a receiving groove 330 is recessed in the inner side wall of the vehicle door 300, and the second rotary connecting seat 13 is disposed in the receiving groove 330. The second rotary connecting seat 13 is installed in the receiving groove 330, so that the height of the second rotary connecting seat 13 overlaps with the thickness of the vehicle door 300. This is beneficial to reducing the overall thickness of the vehicle door 300, reducing the occupation of the interior space by the second rotary connecting seat 13 in the closed door state, and at the same time realizing the hidden installation of the second rotary connecting seat 13.

[0043] Furthermore, reinforcing ribs 30 are provided on the rotary support arm 11 and / or the second rotary connecting seat 13. The rotary support arm 11 and / or the second rotary connecting seat 13 are main load-bearing components, bearing the weight of the vehicle door 300 and the electrical components thereon. By providing the reinforcing ribs 30, the structural strength of the rotary support arm 11 and / or the second rotary connecting seat 13 can be effectively increased, ensuring the reliable assembly and relative rotation of the vehicle door 300 and the vehicle body 200.

[0044] In addition, on the basis of any of the above embodiments, the rotary support assembly 10 further includes a driving motor, a driving gear and a driven gear. The driving motor is drivingly connected to the driving gear, the driving gear meshes with the driven gear, and the driven gear is connected to the first rotary connecting seat 12. During operation, the driving motor, the driving gear and the driven gear cooperate to provide the rotational power for the rotary support arm 11, so as to drive the vehicle door 300 to rotate open or closed. By using the driving gear and the driven gear to mesh with each other, the power transmission can be ensured to be stable, preventing slipping and affecting the normal opening and closing and smoothness.
