In this document, "upper", "lower", "front", "rear", "left", "right", and the like are used only to indicate relative positional relationships between relevant portions, and do not limit absolute positions of the relevant portions.
In order to solve the technical problem that in the prior art, personnel are injured due to the fact that the speed of a car door is too high in the opening and closing processes, the invention provides a door leaf rotating shaft and a car using the door leaf rotating shaft.
As shown in fig. 1, the present embodiment provides a door leaf rotating shaft 10 that is connected to an automobile door 1 and an automobile body (not shown) to rotatably mount the automobile door 1 to the automobile body. Similarly, the vehicle door 1 has a closed position where the door 1 is attached to the vehicle body, and an open position where the door 1 is approximately perpendicular to the vehicle body. It will be appreciated that although the vehicle door 1 can be rotatably mounted to the vehicle body by only one door hinge 10, in order to better support the weight of the vehicle door 1, two or more door hinges 10 may be mounted on each vehicle door 1 up and down along the rotation edge thereof, as shown in fig. 1, that is, a plurality of door hinges 10 are mounted to the vehicle door 1 at intervals in the gravity direction of the vehicle door 1.
As shown in fig. 2, the door leaf rotating shaft 10 includes:
a first rotating member 20 connected to the vehicle body and having a rotating shaft 21 extending upward from an upper surface of the first rotating member 20;
and the second rotating member 30 is connected with the vehicle door 1, and the second rotating member 30 is assembled on the rotating shaft 21 above the first rotating member 20 so as to drive the vehicle door 1 to rotate around the rotating shaft 21.
Fig. 3 is a schematic structural view of a part of the door rotation shaft 10 of fig. 2, fig. 4 is a top view of a part of the door rotation shaft 10 of fig. 2, and the second rotating member 30 is not shown in fig. 3 and 4. As shown in fig. 3 and 4, the upper surface of the first rotating member 20 has a guide rail 22 for guiding the second rotating member 30 to rotate about the rotating shaft 21, and two ends 22a and 22b of the guide rail 22 correspond to the closed position and the open position of the vehicle door 1, respectively. Meanwhile, the lower surface of the second rotating member 30 has a slider 31 that moves along the guide rail 22.
Here, the second rotating member 30 and the slider 31 are integrally moved, so that the position of the slider 31 in the guide rail 22 can indicate the position of the second rotating member 30 relative to the second rotating member 20, and thus the position of the door 1 relative to the vehicle body. That is, as shown in fig. 3 and 4, when the slider 31 is located at one end portion 22a (starting end) of the guide rail 22, the positions of the corresponding second rotating member 31 and the door 1 are the closed position of the vehicle door 1; as shown in fig. 6 and 7, when the slider 31 is located at the other end portion 22b (end) of the guide rail 22, the positions of the corresponding second rotating member 31 and the door 1 are the open position of the vehicle door 1. The opening process of the vehicle door 1 is carried out by the slider 31 of the second rotary part 31 moving along the guide rail 22 from the end 22a to the end 22b of the guide rail 22. The closing process of the vehicle door 1 is carried out by the slider 31 of the second rotary part 31 moving along the guide rail 22 from the end 22b to the end 22a of the guide rail 22.
The sliding block 31 is engaged with the guide rail 22 to define the rotation track of the second rotating member 30 around the rotating shaft 21, and to make the contact between the second rotating member 30 and the first rotating member 20 smoother during the rotation process, which uses the sliding or rolling of the sliding block 31 along the guide rail 22 with less friction instead of the surface contact between the second rotating member 30 and the first rotating member 20 during the rotation process.
Wherein the integral movement of the slider 31 and the second rotating member 30 can be realized by the manner shown in fig. 2. As shown in fig. 2, the second rotating member 30 has a cylindrical hole 33 extending in the vertical direction, and the slider 31 is accommodated in the cylindrical hole 33. Specifically, the slider 31 may be mostly disposed in the cylindrical hole 33, and only a portion that moves along the guide rail 22 may be exposed from the lower surface of the second rotating member 30, and the slider 31 is defined in the cylindrical hole 33 in the extending direction along the guide rail 22, and thus may bring the second rotating member 30 to move integrally therewith when it moves along the guide rail 22.
The guide rail 22 further has a first groove 23, the first groove 23 being located between the two ends 22a and 22b of the guide rail 22, the first groove 23 being adapted to movably confine the slider 31 in the first groove 23 when the slider 31 moves along the guide rail 22 through the first groove 23, to correspondingly movably confine the vehicle door 1 at an angle which the slider 31 now forms with the axis of rotation 21.
In the present embodiment, the first groove 23 is further included between the two ends 22a and 22b of the guide rail 22, which can define the slider 31 therein, i.e., so that the second rotating member 30 and the door 1 can have an intermediate stop position between the open position and the closed position during the opening or closing of the door 1, which can be adjusted as needed, not necessarily at the midpoint between the open position and the closed position.
What has been said above about "movably confining" the slider 31 in the first groove 23 means that the slider 31 can stay in the position of the first groove 23 under the action of gravity when passing through the first groove 23, but can also be moved out of the first groove 23 by the action of a laterally outward force, rather than being permanently confined in the first groove 23.
As can be seen from the above description, the present embodiment can have an intermediate stop position between the open position and the closed position as shown in fig. 5 in the opening process of the vehicle door 1 from fig. 4 to fig. 7 or the closing process of the vehicle door 1 from fig. 7 to fig. 4 by the arrangement of the first groove 23, that is, the sectional opening or closing of the vehicle door 1 can be realized. When a user opens or closes the vehicle door 1, the user can not directly reach the opening or closing position, but firstly reaches the middle stopping position corresponding to the first groove 23, and the user needs to continuously apply the opening or closing external force to open or close the vehicle door 1, so that a buffer space is provided for the opening or closing of the vehicle door 1, and the condition that the user is injured due to the fact that the opening or closing speed is too high due to one-time in-place is avoided.
Further, as described above, a plurality of door spindles 10 may be mounted to each of the vehicle doors 1. Since the door pivot 10 bears the weight of the vehicle door 1, the pretensioning force between the slide 31 and the guide rail 22 of each door pivot 10 is determined by the weight of the vehicle door 1 borne by the door pivot 10. For example, if one door leaf pivot 10 is fitted to each vehicle door 1, the door leaf pivot 10 takes the weight of the entire vehicle door 1; if two door pivots 10 are fitted to each vehicle door 1, each door pivot 10 takes up half the weight of the entire vehicle door 1. Correspondingly, in the vehicle door 1 equipped with two door pivots 10, the pretension between the slide 31 of each door pivot 10 and the guide rail 22 is smaller than in a vehicle door equipped with only one door pivot 10.
Preferably, as shown in fig. 2 and 3 in combination, the second rotating member 30 further has a compression spring 32 disposed in a cylindrical hole 33, one end of the compression spring 32 abuts against the cylindrical hole 33, and the other end is connected to the slider 31. The function of the compression spring 32 is to ensure that the slider 31 is confined in the first groove 23 when passing through the first groove 23, to avoid sliding directly over the first groove 23 due to high speed of movement, etc., and to provide the necessary preload between the slider 31 and the guide rail 22.
When the slider 31 is located in the guide rail 22, the compression spring 32 is in a compressed state, and since it is located below the second rotating member 30, the door 1 and the second rotating member 30 continuously apply a compressive external force thereto. When the slider 31 passes through the first groove 23 along the guide rail 22, the compression spring 32 urges the slider 31 into the first groove 23 under its elastic force due to the depressed structure of the first groove 23 and is confined in the first groove 23, thereby ensuring the staged opening and closing of the vehicle door 1.
Further, as shown in fig. 2, the second rotating member 30 further includes an adjusting nut 34 in threaded connection with the cylindrical hole 33, one end of the compression spring 32 abuts against the adjusting nut 34, and the compression state of the compression spring 32 can be adjusted by the threaded movement of the adjusting nut 34 in the cylindrical hole 33, so as to adjust the preload between the slider 31 and the guide rail 22.
Preferably, the slider 31 is a ball that slides or rolls along the guide rail 22.
As shown in fig. 3 and 8 in combination, the first groove 23 is a circular groove for receiving the ball 31, and the opening diameter of the first groove 23 is smaller than the diameter of the ball 31, so that only a part of the ball 31 is defined in the first groove 23, but not all of the ball 31 is received in the first groove 23. This structure ensures that the ball 31 is movably defined in the first groove 23.
Wherein the peripheral edge of the first groove 23 has a tapered inclined wall 23a extending obliquely downward toward the inside of the first groove 23, and the tapered inclined wall 23a functions to support the ball 31 and to help the ball 31 to smoothly enter and exit the first groove 23.
It will be appreciated that the opening diameter of the first recess 23, the angle of inclination, the height of the tapered inclined wall 23a, etc. can all affect how easily the ball 31 moves out of the first recess 23, i.e., the amount of external force required to move the door 1 out of the intermediate rest position. The adjustment of the parameters can be performed by those skilled in the art according to the actual use requirements.
Further, as shown in fig. 4 and 7, one end 22b of the guide rail 22 corresponding to the open position has a second groove 24, and the second groove 24 is used to movably define the slider 31 in the second groove 24 when the slider 31 moves to the end 22b along the guide rail 22. Wherein the shape of the second groove 24 may be the same as or different from the shape of the first groove 23.
The second recess 24 serves to movably define the door 1 in its open position, and its definition of the slider 31 is the same as that of the first recess 23. When the door 1 opens the door 1 from the intermediate rest position shown in fig. 5 to the open position shown in fig. 7, the slider 31 is confined in the second groove 24 when reaching the end 22b of the guide rail 22, and the slider 31 does not rush out of the guide rail 22 due to excessive force or excessive moving speed. When the door 1 closes the door 1 from the open position shown in fig. 7 to the intermediate stop position shown in fig. 5, a slightly larger external force (slightly larger than in the case where the end portion 22b does not have the second recess 24) needs to be applied to achieve the closing of the door 1, that is, the door 1 can be stopped at the desired open position, avoiding erroneous closing of the door 1 due to, for example, an unintentional collision.
In addition, as can be clearly seen in fig. 5, the end 22a of the guide tube 22 corresponding to the closed position is not provided with a limiting mechanism such as a groove for limiting the slider 31, so that the opening of the vehicle door 1 from the closed position can be free from limitation, and the injury of a user caused by excessive force can be avoided.
In another embodiment, the door leaf rotating shaft 10 of the above-described embodiment can be applied to an automobile. Of course, how the door leaf rotating shaft 10 is installed in the automobile is not the focus of the present invention, and those skilled in the art may implement the installation of the wiper blade 1 in the automobile in any manner, which is not described herein again.
In this document, "a" does not mean that the number of the relevant portions of the present invention is limited to "only one", and "a" does not mean that the number of the relevant portions of the present invention "more than one" is excluded.
It should be understood that although the present description has been described in terms of various embodiments, not every embodiment includes only a single embodiment, and such description is for clarity purposes only, and those skilled in the art will recognize that the embodiments described herein can be combined as a whole to form other embodiments as would be understood by those skilled in the art.
