Technical Field

[0001] The invention relates to a rotating shaft mechanism, in particular to a rotating shaft mechanism used in an automobile air outlet control mechanism. Background Art

[0002] The shaft mechanism includes a rotating member for output and a driving member for driving the rotating member to rotate. In the prior art, the shaft portion of the rotating member is generally directly connected to the driving member, so when the driving member drives the rotating member to rotate, the position of the rotating member may be offset, affecting use. Summary of the invention

[0003] In order to overcome the deficiencies in the prior art, the present invention provides a rotating shaft mechanism which solves the problem of position deviation of the rotating member through multi-directional sliding between the rotating member and the driving member.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A rotating shaft mechanism comprises a rotating member, a driving structure, and a rotating shaft arranged between the rotating member and the driving structure; the driving structure comprises a driving member that drives the rotating member to rotate around the corresponding rotating member rotation axis through the rotating shaft; the rotating member and the driving member can slide in at least two directions.

[0006] The driving member drives the rotating member connected to the rotating shaft to rotate by driving the rotating shaft to rotate; the driving member can rotate in all directions; and one or more rotating members are provided.

[0007] The driving member is rotated to drive the rotating member, and the position of the driving member used to drive the rotating member is called the driving position; taking one of the rotating members as an example, if the rotation axis of the driving member when rotating is always parallel to or coincides with the rotation axis of the rotating member of the rotating member, the position of the driving position of the rotating member will not shift after the driving member rotates; but when the rotation axis of the driving member when rotating is not parallel to or coincides with the rotation axis of the rotating member of the rotating member or the rotation axis of the driving member when rotating changes, the driving position of the rotating member will shift after the driving member rotates; therefore, the driving position of the rotating member before the driving member rotates may shift after the driving member rotates; if the rotating member is directly arranged on the driving member, the position of the rotating member will also shift, and if the position of the rotating member is kept unchanged, the driving member will be stuck or the driving member can only rotate in a specific direction.

[0008] Therefore, by adopting the above structure, the rotating member and the driving member can slide in at least two directions; at this time, the driving member can rotate around a certain axis at will. If the driving position corresponding to the rotating member is offset, the offset is completed by the sliding between the rotating member and the driving member, and the position of the rotating member will not be offset when the driving member is in a universal rotation state.

[0009] If the sliding trajectories are the same or overlap, it is regarded as sliding in one direction, such as sliding to the left and sliding to the right in the same trajectory are regarded as sliding in the same direction; or if sliding in different parallel or concentric sliding paths actually slides to the left or right, the sliding trajectories overlap and are regarded as the same direction.

[0010] Furthermore, the rotating shaft is slidably connected to the rotating member and the driving member respectively, and the sliding direction between the rotating shaft and the rotating member is different from the sliding direction between the rotating shaft and the driving member.

[0011] Specifically, a first slide groove is provided on the side of the rotating shaft facing the driving member, and a second slide bar is provided on the side facing the rotating member; correspondingly, a first slide bar matching the first slide groove is provided on the outer wall of the driving member, and a second slide groove matching the second slide bar is provided on the rotating shaft portion of the rotating member; and the first slide groove and the second slide bar on the rotating shaft are provided in different directions, so as to realize that the sliding direction between the rotating shaft and the rotating member is different from the sliding direction between the rotating shaft and the driving member.

[0012] The above structure is adopted to realize the sliding of the rotating member and the driving member along two directions.

[0013] Furthermore, the first slide groove and the second slide bar arranged on the rotating shaft are arranged in a cross direction.

[0014] By adopting the above structure, the sliding of the rotating shaft between the rotating member and the driving member can be smoother.

[0015] Further, the rotating member includes a first rotating member and a second rotating member, and correspondingly, the rotating shaft includes a first rotating shaft matching the first rotating member, and a second rotating shaft matching the second rotating member.

[0016] With the above structure, the driving member drives the first rotating member to rotate by driving the first rotating shaft; and the driving member drives the second rotating member to rotate by driving the second rotating shaft.

[0017] Further, the rotation axis of the first rotating member is perpendicular to the rotation axis of the second rotating member.

[0018] When the first slide groove and the second slide bar arranged on the rotating shaft are arranged in a cross-shaped direction, the above structure is adopted, and when the rotation axis of the driving member is parallel to or coincides with the rotation axis of the first rotating shaft, the first slide bar on the driving member that matches the first rotating shaft rotates to drive the first rotating shaft to rotate; the first slide bar on the driving member that matches the second rotating shaft slides in the first slide groove in the second rotating shaft, and the first slide bar on the driving member that matches the second rotating shaft does not rotate, that is, the driving member does not rotate the second rotating shaft;

[0019] When the rotation axis of the driving member is parallel to or coincides with the rotation axis of the second rotating shaft, the first slide bar on the driving member that matches the second rotating shaft rotates to drive the second rotating shaft to rotate; the first slide bar on the driving member that matches the first rotating shaft slides in the first slide groove in the first rotating shaft, and the first slide bar on the driving member that matches the first rotating shaft does not rotate, that is, the driving member does not rotate the first rotating shaft; so as to realize the independent driving of the first rotating member or the second rotating member;

[0020] When the rotation axis of the driving member is not parallel or coincident with the rotation axis of the first rotating shaft and the second rotating shaft, the first slide bars on the driving member that match the first rotating shaft and the second rotating shaft both rotate to drive the first rotating shaft and the second rotating shaft to rotate, and the first slide bar on the driving member that matches the first rotating shaft slides in the first slide groove on the first rotating shaft, and the second slide bar on the first rotating shaft slides in the second slide groove on the first rotating member; the first slide bar on the driving member that matches the second rotating shaft slides in the first slide groove on the second rotating shaft, and the second slide bar on the second rotating shaft slides in the second slide groove on the second rotating member, to avoid the rotating shaft mechanism from getting stuck when the first rotating member and the second rotating member are not offset.

[0021] Furthermore, the driving structure includes a universal joint and a base; the driving member is connected to the base via the universal joint to achieve universal rotation of the driving member.

[0022] Furthermore, the universal joint is a cross-axis universal joint.

[0023] Specifically, the universal joint is connected to the base via one of the universal joint shafts, the driving member is connected to the other universal joint shaft of the universal joint, and the two universal joint shafts of the universal joint are perpendicular to each other.

[0024] With the above structure, the driving member can rotate relative to the base around one of the universal joint shafts or around the other universal joint shaft or around both universal joint shafts simultaneously to realize the universal rotation of the driving member.

[0025] Furthermore, at least a portion of the outer wall of the driving member is an outwardly convex arc-shaped spherical surface, and correspondingly, at least a portion of the inner wall of the driving member is an inwardly concave arc-shaped spherical surface; the rotating shaft is connected to the outwardly convex arc-shaped spherical surface of the outer wall of the driving member.

[0026] The above structure enables the driving member to rotate more smoothly.

[0027] Specifically, the first slide groove provided on the rotating shaft and the second slide groove provided on the rotating member are arc-shaped grooves; the first slide bar provided on the driving member and the second slide bar provided on the rotating shaft are arc-shaped slide bars matching the arc-shaped grooves.

[0028] Furthermore, the shaft mechanism includes a support frame having a cavity for installing the drive structure; the rotating member includes a shaft portion and a functional portion rotating around the shaft portion; the cavity extends outward to form a mounting groove for installing the shaft portion.

[0029] Specifically, the mounting groove protrudes toward the shaft portion to form a limiting ridge; correspondingly, the shaft portion is recessed inward to form a limiting groove matching the limiting ridge; the limiting ridge and the limiting groove cooperate with each other to limit the position deviation of the rotating member.

[0030] Furthermore, an operating lever is provided on the driving member, and the operating lever is used for an operator to operate the driving member.

[0031] Compared with the prior art, the present invention has the following beneficial effects: the rotating shaft mechanism of the present invention solves the problem of position deviation of the rotating member through multi-directional sliding between the rotating member and the driving member.

DETAILED DESCRIPTION

[0037] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0038] like Figure 1 —As shown in FIG. 4 , a rotating shaft mechanism comprises a rotating member 1, a driving structure 2, and a rotating shaft 3 arranged between the rotating member 1 and the driving structure 2; the driving structure 2 comprises a driving member 201 which drives the rotating member 1 to rotate around the corresponding rotation axis of the rotating member 1 through the rotating shaft 3; the rotating member 1 and the driving member 201 can slide in at least two directions.

[0039] The driving member 201 drives the rotating member 1 connected to the rotating shaft 3 to rotate by driving the rotating shaft 3 to rotate; the driving member 201 can rotate in all directions; and one or more rotating members 1 are provided.

[0040] The driving member 201 is rotated to drive the rotating member 1, and the position of the driving member 201 for driving the rotating member 1 is called the driving position; taking one of the rotating members 1 as an example, if the rotation axis of the driving member 201 when rotating is always parallel to or coincident with the rotation axis of the rotating member 1 of the rotating member 1, the position of the driving position of the rotating member 1 will not shift after the driving member 201 rotates; but when the rotation axis of the driving member 201 when rotating is not parallel to or coincident with the rotation axis of the rotating member 1 of the rotating member 1 or the rotation axis of the driving member 201 when rotating changes, the driving position of the rotating member 1 will shift after the driving member 201 rotates; therefore, the driving position of the rotating member 1 before the driving member 201 rotates may shift after the driving member 201 rotates; if the rotating member 1 is directly arranged on the driving member 201, the position of the rotating member 1 will also shift, and if the position of the rotating member 1 is kept unchanged, the driving member 201 will be stuck or the driving member 201 can only rotate in a specific direction.

[0041] Therefore, by adopting the above structure, the rotating member 1 and the driving member 201 can slide in at least two directions; at this time, the driving member 201 can rotate around a certain axis at will. If the driving position corresponding to the rotating member 1 is offset, the offset is completed by the sliding between the rotating member 1 and the driving member 201, so that the position of the rotating member 1 will not be offset when the driving member 201 is in a universal rotation state.
