Description

Technical Field

[0001] The present invention relates to the technical field of automobile door production, in particular to a door connecting mechanism and an automobile. Background Art

[0002] With the development of automobile technology, door opening technologies such as scissor doors, seagull doors, and wing doors have appeared on some manufacturers and models. They not only have an aesthetic effect and improve the grade of the car, but also can open the door in a narrow area to avoid ordinary doors from opening and causing damage to pedestrians on the road or the door itself, and the opening method can show one's own personality.

[0003] In traditional technology, scissor doors are mainly divided into: straight-opening type, outward-opening type and hybrid type according to their movement mode. The straight-opening type is a door opening method that opens straight up and down, which has relatively high requirements for the door and the body of the car. It is not applicable to some upgraded models whose appearance cannot be greatly modified. The outward-opening type opens outward first, and then opens upward after opening to a certain angle; the movement trajectory is not smooth enough and the experience is relatively poor. The hybrid door opens outward and upward at the same time, and the movement is smooth without jamming. However, some of the current scissor doors have a large opening angle, which is inconvenient to open after parking, and the stability is poor, which is prone to shaking and deformation, affecting the overall quality of the car. Utility Model Content

[0004] Based on this, it is necessary to provide a door connection mechanism and a car that can effectively improve the installation stability of the scissor door and improve the overall quality of the car.

[0005] The technical solution is as follows: a vehicle door connecting mechanism, which includes: a first base, on which a first connecting part and a second connecting part are arranged at intervals, and the first base is also provided with a matching arm; a second base, on which a third connecting part and a fourth connecting part are provided, the third connecting part is rotatably connected to the first connecting part, and the second base can rotate relative to the first base; a rotating part, which is rotatably connected between the second connecting part and the fourth connecting part; a limit seat, which is connected to the first base, and the limit seat is provided with a limited hollow, and the inner wall of the limit hollow is used for limited cooperation with the matching arm.

[0006] During the installation process of the above-mentioned vehicle door connection mechanism, the limit seat is arranged on the first base, the first base is hinged to each other through the first connecting portion, the third connecting portion, and the rotating member, and then the second base is connected to the vehicle door, and the first base is installed on the vehicle body. In this way, when the vehicle door is opened, the second base rotates relative to the first base through the first connecting portion and the third connecting portion, and the rotating member rotates on the first base and the second base. When the engaging arm rotates into the limiting hollow in the limit seat, it contacts the inner wall of the limiting hollow, thereby forming a limit, causing the vehicle door to swing to the end position, which is beneficial to reducing the opening angle of the vehicle door and preventing the opening of the door from causing harm to pedestrians on the road or the vehicle door itself. In addition, the limit seat, through the limiting hollow, limits the engaging arm, which is beneficial to ensure the stability of the limit, prevents inertial shaking when the vehicle door is opened, and improves the service life of the vehicle door and the overall quality of the vehicle.

[0007] In one embodiment, the limit seat is provided with a first limit block, a second limit block and a third limit block, the first limit block is connected to the third limit block through the second limit block, and the first limit block, the second limit block and the third limit block together form the limit hollow, and the first limit block, the second limit block and the third limit block all form a limit fit with the matching arm.

[0008] In one embodiment, a connecting hole is provided on the third limiting block, and the third limiting block is fastened to the first base by a fastener passing through the connecting hole.

[0009] In one embodiment, a protrusion is provided on the mating arm, and the protrusion is arranged to protrude outward relative to the outer contour of the mating arm. A groove is provided on the inner wall of the limiting hollow, and the outer contour of the protrusion is arranged to correspond to the inner contour of the groove.

[0010] In one embodiment, the vehicle door connection mechanism further includes a ball and pin pair, and the first connection part is connected to the third connection part through the ball and pin pair.

[0011] In one embodiment, the vehicle door connection mechanism further includes a support block, which is sleeved on the ball and pin pair, and the support block is arranged between the gap between the first base and the second base, and the first base is supported and cooperated with the second base through the support block.

[0012] In one embodiment, the first base is provided with a first rotating shaft, the second base is provided with a second rotating shaft, one end of the rotating member is rotatably engaged with the second connecting portion through the first rotating shaft, and the other end of the rotating member is rotatably engaged with the fourth connecting portion through the second rotating shaft.

[0013] In one embodiment, the second connecting portion includes a first rotating seat and a second rotating seat, the first rotating seat and the second rotating seat are spaced apart and arranged on the first base, and the opposite ends of the first rotating shaft are rotatably connected to the first rotating seat and the second rotating seat respectively.

[0014] In one embodiment, the fourth connection portion includes a third rotating seat and a fourth rotating seat, the third rotating seat and the fourth rotating seat are spaced apart and arranged on the second base, and the opposite ends of the second rotating shaft are rotatably connected to the third rotating seat and the fourth rotating seat respectively.

[0015] A car comprises a door, a body and any one of the door connection mechanisms described above, wherein the first base is connected to the body, and the second base is connected to the door.

[0016] During the installation of the aforementioned automobile, the stopper is disposed on the first base, the first base is hingedly connected to the first base via the first connecting portion, the third connecting portion, and the rotating member, the second base is then connected to the vehicle door, and the first base is then mounted on the vehicle body. Thus, when the vehicle door is opened, the second base rotates relative to the first base via the first connecting portion and the third connecting portion, and the rotating member rotates between the first base and the second base. When the engaging arm rotates into the limiting hollow in the stopper, it abuts against the inner wall of the limiting hollow, thereby limiting the swing of the vehicle door to a stop position. This helps reduce the door opening angle and prevents injury to pedestrians or the vehicle door itself. Furthermore, the stopper, through the limiting hollow, limits the engaging arm, ensuring limiting stability, preventing inertial swaying when the vehicle door is opened, and improving the service life of the vehicle door and the overall quality of the vehicle.

[0030] See also Figure 1 , Figure 1 FIG2 shows a schematic diagram of the overall structure of a vehicle door connection mechanism 100 according to one embodiment of the present invention. The vehicle door connection mechanism 100 according to one embodiment of the present invention includes a first base 110, a second base 120, a rotating member 130, and a stopper 140. The first base 110 is provided with a first connecting portion 111 and a second connecting portion 112 spaced apart from each other. The first base 110 also includes a mating arm 123. The second base 120 is provided with a third connecting portion 121 and a fourth connecting portion 122. The third connecting portion 121 is rotatably connected to the first connecting portion 111, allowing the second base 120 to rotate relative to the first base 110. The rotating member 130 is rotatably connected between the second connecting portion 112 and the fourth connecting portion 122. The stopper 140 is connected to the first base 110 and defines a limit opening 144. The inner wall of the limit opening 144 is configured to engage with the mating arm 123 for limited position.

[0031] During the installation process of the above-mentioned vehicle door connecting mechanism 100, the limit seat 140 is set on the first base 110, the first base 110 is hinged to each other through the first connecting part 111, the third connecting part 121 and the rotating part 130, and then the second base 120 is connected to the vehicle door, and the first base 110 is installed on the vehicle body. In this way, when the car door is opened, the second base 120 rotates relative to the first base 110 through the first connecting part 111 and the third connecting part 121, and the rotating part 130 rotates between the first base 110 and the second base 120. When the cooperating arm 123 rotates into the limiting hollow 144 in the limiting seat 140, it contacts the inner wall of the limiting hollow 144 to form a limit, so that the car door swings to the end position, which is beneficial to reducing the opening angle of the car door and avoiding the opening of the door causing harm to pedestrians on the road or the car door itself. In addition, the limiting seat 140 limits the cooperating arm 123 through the limiting hollow 144, which is beneficial to ensure the limiting stability, avoid inertial shaking when the car door is opened, and improve the service life of the car door and the overall quality of the vehicle.

[0032] See also Figure 1 and Figure 2 , Figure 2 The schematic diagram of the structure of the first base 110 described in one embodiment of the present invention is shown; in one embodiment, the limiting seat 140 is provided with a first limiting block 141, a second limiting block 142, and a third limiting block 143. The first limiting block 141 is connected to the third limiting block 143 through the second limiting block 142, and the first limiting block 141, the second limiting block 142, and the third limiting block 143 together form a limiting hollow 144, and the first limiting block 141, the second limiting block 142, and the third limiting block 143 all form a limiting fit with the matching arm 123. In this way, the limiting hollow 144 makes the limiting seat 140 as a whole have a "C"-shaped structure, which can form a limiting fit with the matching arm 123 in three directions. The second base 120 is in a three-sided wrapped state of the limiting seat 140, which can effectively control the inertial swing of the second base 120 from motion to rest in the final stage of operation, thereby further improving the limiting stability.

[0033] Optionally, the connection between the limiting seat 140 and the first base 110 can be screw connection, bolt connection, threaded connection, welding, bonding, snap connection, pin connection or other connection methods. Alternatively, the limiting seat 140 and the first base are an integrally formed structure.

[0034] In one embodiment, see Figure 1 The third stopper 143 is provided with a connection hole, through which a fastener passes to secure the third stopper 143 to the first base 110. For example, the fastener is a screw. This facilitates positioning of the fastener during installation, and the screw connection method is highly reliable and easy to install, thereby improving assembly convenience and stability.

[0035] See also Figure 1 、 Figure 2 and Figure 3 , Figure 3 The schematic diagram of the structure of the second base 120 described in one embodiment of the present invention is shown. In one embodiment, a protrusion 124 is provided on the engagement arm 123. The protrusion 124 is provided to protrude outward relative to the outer contour of the engagement arm 123. The inner wall of the position-limiting hollow 144 is provided with a groove 145. The outer contour of the protrusion 124 corresponds to the inner contour of the groove 145. For example, the protrusion 124 is arc-shaped, and two protrusions 124 are provided on opposite sides of the engagement arm 123, correspondingly, there are two grooves 145. In this way, the protrusion 124 can guide the engagement arm 123 and the position-limiting hollow 144 when they are engaged, and further enhance the position-limiting effect in all directions, thereby eliminating the shaking caused by inertia when the vehicle door is opened.

[0036] In one embodiment, see Figure 1 The door connection mechanism 100 further includes a ball and pin pair 150, through which the first connection portion 111 is connected to the third connection portion 121. In this way, the rotation is flexible, which is conducive to eliminating assembly errors, providing freedom when opening and closing the door, and reducing wear.

[0037] In one embodiment, see Figure 1 The vehicle door connection mechanism 100 further includes a support block 160, which is sleeved on the ball-pin pair 150 and disposed between the first base 110 and the second base 120. The first base 110 is supported and engaged with the second base 120 via the support block 160. Thus, the support block 160 eliminates the assembly gap between the first base 110 and the second base 120, thereby preventing axial movement and improving the structural stability of the vehicle door connection mechanism 100.

[0038] In one embodiment, see Figure 1 The first base 110 is provided with a first rotating shaft 113, and the second base 120 is provided with a second rotating shaft 125. One end of the rotating member 130 is rotatably engaged with the second connecting portion 112 via the first rotating shaft 113, and the other end of the rotating member 130 is rotatably engaged with the fourth connecting portion 122 via the second rotating shaft 125. In this way, the guidance and stability of the second base 120 when rotating relative to the first base 110 can be guaranteed.

[0039] In one embodiment, see Figure 2The second connecting portion 112 includes a first rotating base 114 and a second rotating base 115. The first rotating base 114 and the second rotating base 115 are spaced apart and arranged on the first base 110. The opposite ends of the first rotating shaft 113 are rotatably connected to the first rotating base 114 and the second rotating base 115. In this way, the two rotating bases support the first rotating shaft 113, which can prevent the first rotating shaft 113 from being bent due to localized force, thereby improving rotational stability and service life.

[0040] See also Figure 3 , Figure 3 A schematic diagram of the structure of the second base 120 described in one embodiment of the present invention is shown. In one embodiment, the fourth connecting portion 122 includes a third rotating base 126 and a fourth rotating base 127. The third rotating base 126 and the fourth rotating base 127 are spaced apart and arranged on the second base 120. The third rotating base 126 and the fourth rotating base 127 are rotatably connected to the opposite ends of the second rotating shaft 125. In this way, the second rotating shaft 125 is supported by two rotating bases, which can prevent the first rotating shaft 113 from being locally stressed and causing bending deformation, thereby improving rotational stability and service life.

[0041] In one embodiment, a car (not shown) includes a door, a body, and any one of the door connection mechanisms 100 described above, wherein the first base 110 is connected to the body, and the second base 120 is connected to the door.

[0042] During the installation of the above-mentioned car, the limit seat 140 is set on the first base 110, the first base 110 is hinged to each other through the first connecting part 111, the third connecting part 121 and the rotating part 130, and then the second base 120 is connected to the car door, and the first base 110 is installed on the car body. In this way, when the car door is opened, the second base 120 rotates relative to the first base 110 through the first connecting part 111 and the third connecting part 121, and the rotating part 130 rotates between the first base 110 and the second base 120. When the cooperating arm 123 rotates into the limiting hollow 144 in the limiting seat 140, it contacts the inner wall of the limiting hollow 144 to form a limit, so that the car door swings to the end position, which is beneficial to reducing the opening angle of the car door and avoiding the opening of the door causing harm to pedestrians on the road or the car door itself. In addition, the limiting seat 140 limits the cooperating arm 123 through the limiting hollow 144, which is beneficial to ensure the limiting stability, avoid inertial shaking when the car door is opened, and improve the service life of the car door and the overall quality of the vehicle.

[0043] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
