Description
Technical Field
The invention relates to the field of automobile handles, in particular to an automobile door handle assembly for an automobile.
Background
A known door handle assembly for a vehicle has a door handle body for pulling operation by a user, and a bracket is provided on an inner side of a vehicle door in order to mount the door handle body on the vehicle door. The door handle body is connected to the bracket at the inner side of the vehicle door via support arms at both ends thereof, and the two support arms extend into the bracket from the outer side through openings in the vehicle door case, respectively. The handle body can occupy two positions, namely a rest position and an open position, with respect to the vehicle door. The handle body can be pivoted from a rest position into an open position in an opening movement. In the open position, the support arm at one end of the handle body is at least partially pulled out of the interior of the door in the opening of the door shell, and the support arm at the opposite end is held on the bracket and pivots about an axis or point disposed within the bracket. When the door handle assembly is pivoted, the gap between the handle body and the supporting arm thereof and the edge of the door shell opening is reduced to be collided, so that the door handle assembly must be avoided in consideration of the movement track of the handle body when designing the door shell opening.
Disclosure of Invention
The object of the invention is to further improve the door handle assembly of a vehicle on the basis of the prior art in such a way that the door handle assembly does not collide with the door shell when pivoting and is more flexible in design.
The invention achieves the purpose by the following technical scheme:
a door handle assembly for a vehicle door, having: a bracket fixed to an inner side of the door housing; and a handle body provided on an outer side of the door, the handle body having a first end portion provided on the bracket through an opening of the door case from the outer side of the door and a second end portion pivotably provided on the bracket through the opening of the door case from the outer side of the door, the second end portion including a support arm having a curved portion, wherein a circular arc-shaped guide rail is formed in the bracket so that the support arm of the second end portion is slidable within the bracket pivotably about a center of the circular arc-shaped guide rail. The circular arc in the present invention refers to a circular arc on a perfect circle. The present invention improves upon the prior art by artificially defining a virtual pivot center of the handle body through a circular arc-shaped guide rail for guiding a support arm of the second end portion of the handle body to perform a sliding motion in the bracket when the handle body is pivoted, thereby optimizing the movable disposition of the door handle assembly on the door shell.
The circular arc guide rail in the bracket forms the actual motion track of the support arm of the second end part of the handle body in the bracket in a pivoting sliding mode, namely the support arm of the second end part of the handle body in the bracket slides on the circular arc guide rail. The circular arc-shaped guide rail is structurally defined by the bracket and/or the parts in the bracket and the support arm of the second end of the handle body and is uniquely defined, and accordingly, the center of the circle of the circular arc-shaped guide rail is uniquely defined. However, since the circular arc-shaped guide track can be defined by the bracket and/or the contact surfaces and/or points of contact between the part in the bracket and the support arm of the second end of the handle body with each other, and theoretically only three points are needed to define the center of a circle, these contact surfaces and/or points of contact can be distributed only locally on and define the circular arc-shaped trajectory of the actual movement of the rotation of the support arm of the second end of the handle body in the bracket, the circular arc-shaped guide track can be partially virtual in nature, i.e. not visible on the part, but uniquely defined.
The supporting arm at the second end of the handle body can pivotally move around the circle center of the circular arc guide rail, namely the circle center of the circular arc guide rail defines the pivot center of the whole handle body moving from the rest position to the maximum opening position. The contact surfaces and/or points of contact between the bracket and/or the parts in the bracket and the support arm of the second end of the handle body with each other may be arranged such that the support arm of the second end of the handle body can slide within the guide track of circular arc shape pivotably about the centre of the guide track of circular arc shape through an angle at least equal to or greater than the angle of pivoting of the handle body about the centre of rotation from the rest position to the maximum open position.
According to one embodiment of the invention, the centre of the arc-shaped guide rail is located in the door shell or on the exterior of the door shell facing away from the vehicle. That is, when the handle body is pulled, the center of rotation of the pivotal movement is located in the door shell or at the exterior of the door shell facing away from the vehicle. By utilizing the principle that the equal-length straight lines on the circle have equal distances from any position to the circle center, the handle body and the supporting arm thereof can bypass the edge of the opening of the vehicle door shell on one side of the opening of the supporting arm in the opening moving direction of the supporting arm when pivoting, and the collision with the vehicle door shell is successfully avoided.
According to an embodiment of the present invention, the bracket has a slide rail member which is in contact with one side of the curved portion notch of the support arm of the second end portion of the handle body, and the support arm of the second end portion of the handle body is supported on the bracket body on the side of the curved portion notch. The support arm of the second end of the handle body slides in a slot formed between the slide member and the bracket body, the slot at least partially coinciding with the circular arc guide rail. The slide member may be mounted as an additional insert in the holder. The circular arc guide rail can be flexibly designed to set the position of the circle center through the additional slide rail element. Alternatively, the rail element can also be formed integrally in the carrier, in which case it is easy to form the rail element directly in the mold.
According to the above embodiment, the contact between the slide rail element and the support arm at the second end of the handle body and/or the contact between the support arm at the second end of the handle body and the bracket body are arranged so that the handle body cannot be limited or moved in the bracket in the X-axis direction of the automobile, which is beneficial to make the pivoting motion of the handle body more stable and the circle center of the circular arc guide rail fixed.
According to the above-described embodiment, the slide rail member and the support arm of the second end portion of the handle body can be in contact with each other via the contact surface and/or the contact point, and the curved portion of the support arm of the second end portion of the handle body can be supported on the bracket body on the side of the boss opening via the contact surface and/or the contact point, so that the circular arc-shaped movement locus along which the support arm can pivotally slide can be uniquely determined in the bracket. For example, the support arm at the second end of the handle body is in contact with the slide rail member or the bracket body through at least one contact surface on one side of the recess and the projection of the curved portion of the support arm at the second end of the handle body, and then the support arm at the second end of the handle body is in contact with the slide rail member or the bracket body through at least one contact surface or contact point on the other side; it is also possible that the support arm at the second end of the handle body is in contact with the slide rail member or the bracket body at one side of the recess and the projection of the curved portion of the support arm at the second end of the handle body through at least two contact points, and the support arm at the second end of the handle body is in contact with the slide rail member or the bracket body at the other side through at least one contact surface or contact point. The contact point or contact surface between the support arm of the second end of the handle body and the rail element or the bracket body can be realized by a support surface or support point. The support point may be provided on one of the support arm of the second end of the handle body or on one of the slide member and on one of the support arm of the second end of the handle body or on one of the bracket bodies. The support surface may be provided on one of the support arm or the slide member of the second end portion of the handle body and on one of the support arm or the bracket body of the second end portion of the handle body, or the support surface may be provided on both the support arm of the second end portion, the slide member and the bracket body.
According to one embodiment of the invention, the door handle assembly for a vehicle door is a concealed door handle assembly, the door handle body being movable at least between a rest position in which the door handle body is flush with the door shell and an open position in which the door handle body is extendable from the door shell. The hidden door handle component does not protrude out of the shell of the automobile body when the automobile runs, so that the air resistance is reduced, and the requirements of energy conservation and environmental protection of the automobile, particularly a new energy automobile, are met. In addition, the concealed door handle assembly requires high sealability with respect to the vehicle door housing and also requires high dimensional or installation tolerances of movable parts, which can be easily satisfied by defining the rotation track of the handle body in the bracket so that the design of the door housing is not restricted by the movement of the door handle body.

Detailed Description
The invention is further illustrated by the following specific examples.
Examples
The invention is further illustrated by the following figures. When referring to the same parts, the same reference numbers are used in the various figures.
Fig. 1 to 3 show an embodiment according to the present invention. A door handle assembly for a vehicle door 1 has a bracket 2 and a handle body 3, the bracket 2 being fixed to the inside of a door housing 1, and the handle body 3 being mounted to the outside of the door housing 1. The handle body 3 has a first end portion 3a and a second end portion 3b, both the first end portion 3a and the second end portion 3b being provided on the bracket 2, and the second end portion 3b has a support arm 4 with a bent portion. The bracket 2 has an additional slide element 5 in it, the side 5a of the slide insert 5 facing the recess of the curved portion of the support arm 4 at the second end 3b of the handle body being rounded (seen in the direction of the Z-axis of the vehicle). In the exemplary embodiment of fig. 1 to 3, the support arm 4 of the handle body second end 3b has two support points 4a and 4b, the two support points 4a and 4b resting on the circular arc surface 5a of the rail element as contact points between the support arm 4 of the handle body second end 3b and the rail element 5. The support arm 4 of the handle body second end 3b rests on the bracket body 2 on the side of its curved part lip, which has a support point 2a at the contact. The support arm 4 of the handle body second end 3b can thus slide pivotably in the space between the bracket body 2 and the slide rail element 5, in particular in the space between the contact points 4a, 4b and 2a, in the bracket 2 along the circular arc-shaped side of the slide rail element 5, the centre o of which corresponds to the circular arc-shaped side of the slide rail element 5 also being the centre o of rotation of the support arm 4 of the handle body second end 3b, i.e. of the entire handle body 3. The space track that the second end portion 3b of the handle body supports the arm 4 slides in the bracket, namely the circular arc guide rail t in the bracket (in order to more intuitively show the relation between the guide rail and the circle center, the whole circle of the guide rail t is marked in the drawing). By changing the arc of the arc surface of the slide rail element 5, the ideal circle center o, namely the position of the pivot center o of the handle body 3, can be easily changed.
In fig. 1 to 3, the center o is set on the surface of the door housing 1. Fig. 1 shows the handle body 3 in the rest position, and fig. 3 shows the handle body 3 in the open position, the handle body 3 being able to be pulled out manually by the user about the pivot center o or pushed out by motor drive. It can be seen that, since the equal-length straight lines on the circle are equidistant from the center of the circle at any position, the handle body 3 does not have a tendency to move toward the inside of the bracket 2 and to the left in fig. 1 and 3 when rotated about the pivot center, and therefore does not collide with the door shell 4 adjacent to the left side thereof.
Fig. 4 to 6 show another embodiment of the invention, which differs from the embodiment of fig. 1 to 3 in that the rail element 5' is not additionally provided but is integrally formed on the carrier 2, the rail element 5' likewise having a circular arc-shaped side surface 5a '. The support arm 4 of the handle body second end 3b rests on the arc-shaped surface 5a 'of the slide element from two support points 4a and 4b, the two support points 4a and 4b serving as contact points between the support arm 4 of the handle body second end 3b and the slide element 5' with respect to one another. The support arm 4 of the handle body second end 3b rests on the bracket body 2 on the side of its curved part lip, which at the contact has a support surface 2b, which support surface 2b abuts the support arm 4 of the handle body second end 3b at its curved part lip. The support arm 4 of the handle body second end 3b can thus slide pivotably along the circular arc-shaped side 5a ' of the rail element 5' in the bracket 2 in the gap between the contact points 4a, 4b and 2b, the center o ' of the circular arc-shaped side of the rail element 5' also being the pivot center o ' of the support arm 4 of the handle body second end 3b, i.e. of the entire handle body 3. The space trajectory that the support arm 4 of the second end portion 3b of the handle body traces when sliding in the bracket is a circular arc guide rail t' (in order to more intuitively show the relationship between the guide rail and the center of a circle, the whole circle where the guide rail t is located is marked in the drawing). By changing the arc of the arc-shaped side of the slide rail element 5', the position of the ideal center o ', i.e. the pivot center o ' of the handle body 3, is easily obtained.
Similarly to the embodiment of fig. 1 to 3, in fig. 4 to 6, a center o ', i.e., a pivot center o' is also provided on the surface on which the door housing 1 is located. Fig. 4 shows the case where the handle body 3 is in the rest position where the outer surface of the handle body 3 is flush with the door shell 1. Fig. 6 shows the handle body 3 in the open position, and the handle body 3 can be manually pulled out around the rotation center o' by a user or pushed out by motor driving. It can be seen that, since the equal-length straight lines on the circle are equidistant from the center of the circle at any position, the handle body 3 does not tend to move toward the inside of the bracket 2 and to the left in fig. 4 and 6 when rotated about the pivot center o', and therefore does not collide with the door housing 4 adjacent to the left side thereof.
In the embodiments of fig. 1 to 3 and the embodiments of fig. 4 to 6, the contact manner of the support arm 4 of the second end portion 3b of the handle body with the slide rail members 5 and 5' or the bracket body 2 is not limited to the one shown in the drawings, and the contact surface type contact and the contact point type contact can be used alternatively as long as the circle center of the circular arc motion locus of the support arm 4 of the second end portion 3b of the handle body can be uniquely determined by the combination of the contact manner/the contact manner.
The embodiment of fig. 1 and 3 and the embodiment of fig. 4 and 6 are also not limited to a concealed door handle assembly that is flush with the surface of the vehicle door in the rest position. The embodiment of fig. 1 and 3 and the embodiment of fig. 4 and 6 can alternatively be used with the handle body projecting from the surface of the vehicle door in the rest position.
Fig. 7 to 10 show schematic views of a door handle assembly for a vehicle door according to the present invention, in which the individual parts of the handle assembly are identified only by simplified figures.
The handle body 3 has a support arm 4 at one end thereof, the specific shape of the support arm 4 is not limited to the standard circular arc shape shown in the diagram, and the support arm 4 is rotatably slidable on a circular arc shaped track t 'having a center o' in a bracket (not shown in fig. 7 to 10) of the door handle assembly inside the door shell. In fig. 7 and 8, the center o ″ of the circular arc track t ″ lies on the outer side of the door shell facing away from the vehicle. The radius from the edge of the handle body 3 closest to the door shell to the circle center o' is r. When the handle body is pivotally moved from the rest position shown in fig. 7 to the open position shown in fig. 8, the handle body 3 makes a counterclockwise rotational movement as indicated by an arrow along the circular arc orbit p whose radius is r around the center o ″ and since the equal-length straight lines on the circle are equidistant from the center at any position, it can be seen that the handle body 3 does not collide with the door housing 1 when the handle body 3 is pivoted toward the outside of the door.
Fig. 9 and 10 are different from fig. 7 and 8 in that the center o '″ of fig. 9 and 10 is located in the door housing, and when the handle body 3 performs counterclockwise rotational movement as indicated by an arrow along the circular arc orbit p' with the radius r 'around the center o' ″, since the equal-length straight lines on the circle are equidistant from the center at any position, it can be seen that the handle body 3 does not collide with the door housing 1 when the handle body 3 is pivoted toward the outside of the door.
The foregoing description of the embodiments describes the invention in the context of examples only. Of course, the individual features of the embodiments can be freely combined with one another as long as they are technically reasonable without departing from the scope of the invention.
