Description

Technical Field

[0001] This invention relates to a drive device, an air conditioning vent assembly, and a vehicle. Background Technology

[0002] Vehicles involve many switching components or adjustment mechanisms, such as the airflow direction adjustment mechanism of the air vents and the various damper switches in the air distributor. These are usually controlled by a single motor to individually control the switching of the switching components or the state adjustment of the adjustment mechanism.

[0003] It is obvious that the existing control method will greatly increase the number of motors, which in turn will lead to high costs for vehicle parts. Therefore, how to reduce the number of motors is a technical problem worth studying. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a driving device that can save the number of motors.

[0005] The present invention discloses a driving device comprising a housing and a turntable, a first transmission member, a second transmission member, a first output rod, and a second output rod disposed within the housing; the turntable has a first track groove and a second track groove; the first output rod includes a first driving part and a first sliding straight groove, the first driving part extending outside the housing for connecting to and driving a first external part; the second output rod includes a second driving part and a second sliding straight groove, the second driving part for connecting to and driving a second external part; the first and second output rods are configured to only perform translational motion; the first transmission member includes a first transmission part and a second transmission part, the first transmission part being slidably disposed within the first track groove, and the second transmission part being slidably disposed within the first sliding straight groove; when the turntable rotates, the first transmission member is driven to move through the linkage between the first track groove and the first transmission part, and simultaneously, the first transmission member moves through the linkage between the second transmission part and the first sliding straight groove. The linkage causes the first output rod to translate in the first direction, and the first sliding groove allows the first output rod to translate in the second direction, which is perpendicular to the second direction. The second transmission component includes a third transmission part and a fourth transmission part. The third transmission part is slidably disposed in the second track groove, and the fourth transmission part is slidably disposed in the second sliding groove. When the turntable rotates, the linkage between the second track groove and the third transmission part causes the second transmission component to move. At the same time, the movement of the second transmission component causes the second output rod to translate in the first direction through the linkage between the fourth transmission part and the second sliding groove. The second sliding groove allows the second output rod to translate in the second direction. The rotation angle of the turntable includes several continuous angle intervals. Within at least one angle interval, the rotation of the turntable can cause the first output rod and the second output rod to have different displacements and / or opposite displacement directions in the first direction.

[0006] In a preferred embodiment, the first transmission member and the second transmission member are respectively a first rotating member and a second rotating member; the first driving part includes at least two first connecting parts distributed along a first direction; the second driving part includes at least two second connecting parts distributed along the first direction; and both the second transmission part and the fourth transmission part are sliding shafts.

[0007] Furthermore, the lengths of the first sliding groove and the second sliding groove extend along the second direction.

[0008] In another preferred embodiment, the first transmission member and the second transmission member are respectively a first translation member and a second translation member, which can translate along the first direction; the second transmission part can restrict the rotation of the first output rod while sliding with the first sliding groove; the fourth transmission part can restrict the rotation of the second output rod while sliding with the second sliding groove; the length directions of the first sliding groove and the second sliding groove form an acute angle with the first direction.

[0009] Preferably, both the second and fourth transmission parts are sliding blocks.

[0010] Preferably, both the second and fourth transmission parts include two sliding shafts.

[0011] Furthermore, it also includes a motor housed inside the housing, whose shaft is connected to the turntable and can drive the turntable to rotate.

[0012] Preferably, the turntable includes a first end face and a second end face with two opposite sides, and the first end face and the second end face respectively have a first track groove and a second track groove.

[0013] Preferably, the turntable is cylindrical, and the side of the turntable has a first track groove and a second track groove.

[0014] The present invention also proposes an air conditioning outlet assembly, including the driving device described above.

[0015] The present invention also proposes a vehicle including an air conditioning vent assembly as described above.

[0016] The beneficial effect of this invention is that the drive device has two output rods. When only a single motor is used as the power input, the effect of two power outputs can be achieved through two output rods with different motion logics. They can control two different external parts to move along different trajectories, realizing the function that originally required two motors, thus reducing the overall cost. In addition to driving the external parts by translating in the first direction, if the external parts also have displacement in the second direction, the output rods can also move in the second direction along with the external parts.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1, refer to Appendix Figure 1-5 A driving device includes a housing 10 consisting of a base 11, a cover plate 12, and a motor cover 13. A motor 70 is installed in the cavity formed by the cover plate 12 and the motor cover 13. A turntable 20, a first rotating component 301, a second rotating component 401, a first output rod 50, and a second output rod 60 are installed in the cavity formed by the base 11 and the cover plate 12. The rotating shaft of the motor 70 is connected to the turntable 20 and can drive the turntable 20 to rotate. Turntable 20 includes a first end face and a second end face with two opposite sides, and the first end face and the second end face respectively have a first track groove 21 and a second track groove 22; The first output rod 50 includes a first driving part 51 and a first sliding groove 52. The first driving part 51 extends out of the housing 10 to connect to and drive the first external part 80. The second output rod 60 includes a second driving part 61 and a second sliding groove 62. The second driving part 61 is used to connect to and drive the second external part 90. The first output rod 50 and the second output rod 60 are configured to only perform translational movements. In this embodiment, the first driving part 51 includes two first connecting parts 511 distributed along a first direction. The first connecting parts 511 are used to connect to the first external part 80, thereby restricting the first driving part 51 to only perform translational movements. Similarly, the second driving part 61 includes two second connecting parts 611 distributed along a first direction. The second connecting parts 611 are used to connect to the second external part 90, thereby restricting the second driving part 61 to only perform translational movements. The first rotating component 301 includes a first transmission part 31 and a second transmission part 32. The first transmission part 31 is slidably disposed in the first track groove 21, and the second transmission part 32 is slidably disposed in the first sliding straight groove 52. When the turntable 20 rotates, the first rotating component 301 is driven to rotate through the linkage between the first track groove 21 and the first transmission part 31. Simultaneously, the first rotating component 301 rotates, and the first output rod 50 is driven to translate in the first direction through the linkage between the second transmission part 32 and the first sliding straight groove 52. The presence of the first sliding straight groove 52 allows the first output rod 50 to also translate in the second direction. The first direction is perpendicular to the second direction, thus... Figure 2 For reference, the horizontal axis is the first direction and the vertical axis is the second direction; in this embodiment, both the first transmission part 31 and the second transmission part 32 are sliding shafts. The second rotating component 401 includes a third transmission part 41 and a fourth transmission part 42. The third transmission part 41 is slidably disposed in the second track groove 22, and the fourth transmission part 42 is slidably disposed in the second sliding straight groove 62. When the turntable 20 rotates, the second rotating component 401 is driven to rotate through the linkage between the second track groove 22 and the third transmission part 41. At the same time, the second rotating component 401 rotates, and the second output rod 60 is driven to translate in the first direction through the linkage between the fourth transmission part 42 and the second sliding straight groove 62. The presence of the second sliding straight groove 62 allows the second output rod 60 to also translate in the second direction. In this embodiment, both the third transmission part 41 and the fourth transmission part 42 are sliding shafts. The rotation angle of the turntable 20 includes several continuous angle intervals. Within at least one angle interval, the rotation of the turntable 20 can cause the first output rod 50 and the second output rod 60 to have different displacements and / or opposite displacement directions in the first direction.

[0024] In this embodiment, the drive device has two output rods. When only a single motor 70 is used as the power input, the effect of two power outputs can be achieved through two output rods with different motion logics. These two output rods can control two different external parts to move along different trajectories, realizing the functions that originally required two motors 70, thus reducing the overall cost. In addition to driving the external parts by translating in the first direction, if the external parts also have displacement in the second direction, the output rods can also move in the second direction along with the external parts.

[0025] The motion principle of the first output rod 50 and the second output rod 60 of the driving device in this embodiment is as follows: The turntable 20 is driven to rotate by the motor 70. While the turntable 20 is rotating, it pushes the first transmission part 31 of the first rotating member 301 to move through the first track groove 21, thereby driving the first rotating member 301 to rotate. At the same time as the first rotating member 301 rotates, the second transmission part 32 on it rotates synchronously. Since the second transmission part 32 can slide in the first sliding straight groove 52 of the first output rod 50, the second transmission part 32 can drive the first output rod 50 to generate displacement in the first direction, thereby enabling the first driving part 51 of the first output rod 50 to drive the first external part 80 to translate in the first direction.

[0026] Similarly, as the turntable 20 rotates, it pushes the third transmission part 41 of the second rotating member 401 to move through the second track groove 22, thereby driving the second rotating member 401 to rotate. At the same time as the second rotating member 401 rotates, the fourth transmission part 42 on it rotates synchronously. Since the fourth transmission part 42 can slide in the second sliding straight groove 62 of the second output rod 60, the fourth transmission part 42 can drive the second output rod 60 to generate displacement in the first direction, thereby enabling the second drive part 61 of the second output rod 60 to drive the second external part 90 to translate in the first direction.

[0027] There are two key points in the overall motion logic of the drive device in this embodiment: The first constraint is the degree of freedom of the first output rod 50. If the first output rod 50 can rotate, the movement of the output rod of the drive device as a power output will inevitably be problematic. Therefore, the first output rod 50 can only effectively drive the first external part 80 by being restricted to translational movement. In this embodiment, the first output rod 50 is restricted to translational movement by using external parts to restrict the rotation of the first drive part 51. Specifically, the first drive part 51 has two first connecting parts 511 distributed along the first direction. The function of the two first connecting parts 511 is to connect with the corresponding two connecting parts on the first external part 80. After connection, as long as the two connecting parts on the first external part 80 cannot rotate, the degree of freedom constraint can be transmitted to the first drive part 51 and the rotation of the first drive part 51 can be restricted. If the first drive part 51 cannot rotate, the first output rod 50 cannot rotate either and can only perform translational movement.

[0028] Secondly, there is the displacement of the first output rod 50 in the second direction. Since the first external part 80 may have various movements, such as linear motion, circular motion, or curvilinear motion, linear motion can be directly converted into displacement in the first direction. However, circular motion or curvilinear motion results in displacement in both the first and second directions. Therefore, in some application scenarios, the first output rod 50 also needs to move in the second direction along with the first external part 80. At the same time, the second transmission part 32 of the first rotating part 301 also has displacement in the second direction when it rotates. The displacement direction and displacement amount of the first output rod 50 and the second transmission part 32 in the second direction cannot be the same, and there must be a conflict. In this embodiment, the first sliding groove 52 of the first output rod 50 is to counteract the movement conflict between the first output rod 50 and the second transmission part 32 in the second direction during the actual movement, so that the first output rod 50 can translate with the first external part 80 in the second direction. The motion principles of the first output rod 50 and the second output rod 60 are basically the same, so the key points of the motion of the second output rod 60 will not be repeated.

[0029] In this embodiment, in order to facilitate the calculation of the displacement of the first output rod 50 and the second output rod 60 in the first direction, the lengths of the first sliding straight groove 52 and the second sliding straight groove 62 extend along the second direction.

[0030] In another embodiment, the turntable 20 is cylindrical and has a first track groove and a second track groove on its side. Other structures are similar. When the turntable 20 rotates, it pushes the first rotating member 301 and the second rotating member 401 to move through the first track groove and the second track groove, respectively.

[0031] Example 2, see attached document Figure 6-7A driving device includes a housing 10 consisting of a base 11, a cover plate 12, and a motor cover 13. A motor 70 is installed in the cavity formed by the cover plate 12 and the motor cover 13. A turntable 20, a first translation member 302, a second translation member 402, a first output rod 50, and a second output rod 60 are installed in the cavity formed by the base 11 and the cover plate 12. The rotating shaft of the motor 70 is connected to the turntable 20 and can drive the turntable 20 to rotate. Turntable 20 includes a first end face and a second end face with two opposite sides, and the first end face and the second end face respectively have a first track groove 21 and a second track groove 22; The first output rod 50 includes a first drive part 51 and a first sliding groove 52. The first drive part 51 extends out of the housing 10 and includes a first connecting part 511 for connecting and driving the first external part 80. The second output rod 60 includes a second drive part 61 and a second sliding groove 62. The second drive part 61 extends out of the housing 10 and includes a second connecting part 611 for connecting and driving the second external part 90. The first output rod 50 and the second output rod 60 are configured to only perform translational movements. The first translation member 302 can translate along a first direction and includes a first transmission part 31 and a second transmission part 32. The first transmission part 31 is slidably disposed in the first track groove 21, and the second transmission part 32 is slidably disposed in the first sliding straight groove 52. The second transmission part 32 and the first sliding straight groove 52 can restrict the rotation of the first output rod 50 while slidingly engaging. When the turntable 20 rotates, the first translation member 302 is driven to translate through the linkage between the first track groove 21 and the first transmission part 31. At the same time, the first translation member 302 is driven to translate in the first direction through the linkage between the second transmission part 32 and the first sliding straight groove 52. The presence of the first sliding straight groove 52 allows the first output rod 50 to also translate in the second direction. The first direction is perpendicular to the second direction. In this embodiment, the first transmission part 31 and the second transmission part 32 are a sliding shaft and a sliding block, respectively. The sliding block and the first sliding straight groove 52 can restrict the rotation of the first output rod 50. The second translation member 402 can translate along the first direction and includes a third transmission part 41 and a fourth transmission part 42. The third transmission part 41 is slidably disposed in the second track groove 22, and the fourth transmission part 42 is slidably disposed in the second sliding straight groove 62. The fourth transmission part 42 and the second sliding straight groove 62 can restrict the rotation of the second output rod 60 while slidingly engaging. When the turntable 20 rotates, the second translation member 402 is driven to translate through the linkage between the second track groove 22 and the third transmission part 41. At the same time, the second translation member 402 is driven to translate in the first direction through the linkage between the fourth transmission part 42 and the second sliding straight groove 62. The presence of the second sliding straight groove 62 allows the second output rod 60 to also translate in the second direction. In this embodiment, the third transmission part 41 and the fourth transmission part 42 are also a sliding shaft and a sliding block, respectively. The sliding block and the second sliding straight groove 62 can restrict the rotation of the second output rod 60. The rotation angle of the turntable 20 includes several continuous angle intervals. Within at least one angle interval, the rotation of the turntable 20 can cause the first output rod 50 and the second output rod 60 to have different displacements and / or opposite displacement directions in the first direction.

[0032] The motion principle of the first output rod 50 and the second output rod 60 of the driving device in this embodiment is as follows: The turntable 20 is driven to rotate by the motor 70. While the turntable 20 is rotating, it pushes the first transmission part 31 of the first translation member 302 to move through the first track groove 21, thereby driving the first translation member 302 to translate. At the same time as the first translation member 302 translates, the second transmission part 32 on it translates synchronously. Since the second transmission part 32 can slide in the first sliding straight groove 52 of the first output rod 50, the second transmission part 32 can drive the first output rod 50 to generate displacement in the first direction, thereby enabling the first drive part 51 of the first output rod 50 to drive the first external part 80 to translate in the first direction.

[0033] Similarly, as the turntable 20 rotates, it pushes the third transmission part 41 of the second translation member 402 to move through the second track groove 22, thereby driving the second translation member 402 to translate. At the same time as the second translation member 402 translates, the fourth transmission part 42 on it translates synchronously. Since the fourth transmission part 42 can slide in the second sliding straight groove 62 of the second output rod 60, the fourth sliding block can drive the second output rod 60 to generate displacement in the first direction, thereby enabling the second drive part 61 of the second output rod 60 to drive the second external part 90 to translate in the first direction.

[0034] Similar to Example 1, there are two key points in the overall motion logic of this example: The first constraint is on the degree of freedom of the first output rod 50. In this embodiment, the first output rod 50 is limited to translational movement by restricting the rotation of the first sliding groove 52 through the second transmission part 32 on the first translation member 302. Specifically, the second transmission part 32 is a sliding block with a certain length. Since the sliding block is part of the first translation member 302, it moves with the first translation member 302. Therefore, the sliding block cannot rotate. After the sliding block is connected to the first sliding groove 52, the degree of freedom constraint can be transmitted to the first drive part 51 and the rotation of the first drive part 51 can be restricted. If the first drive part 51 cannot rotate, the first output rod 50 cannot rotate either and can only move in translation.

[0035] The second is the displacement of the first output rod 50 in the second direction; since the first translation member 302 has been limited to translational movement only, and the first output rod 50 may need to follow the first external part 80 in the second direction to move, in this embodiment, the first sliding straight groove 52 of the first output rod 50 is to enable the first output rod 50 to move in translational movement with the first external part 80 in the second direction. Since the motion principles of the first output rod 50 and the second output rod 60 are basically the same, the key points of the motion of the second output rod 60 will not be elaborated here.

[0036] In this embodiment, the length directions of the first sliding straight groove 52 and the second sliding straight groove 62 form an acute angle with the first direction. The smaller the acute angle, the smoother the translation of the first sliding straight groove 52 and the second sliding straight groove 62 in the second direction, but the smaller the maximum translation distance.

[0037] In another embodiment, the second and fourth sliding blocks can be replaced by two sliding shafts, the contact area between the two sliding shafts and the sliding groove being smaller than the contact area between the sliding block and the sliding groove.

[0038] The technical effects of Embodiment 1 are also present in this embodiment. On this basis, the applicability of the drive device in this embodiment is wider than that of the drive device in Embodiment 1. Since the first output rod 50 and the second output rod 60 in this embodiment do not require external parts to restrict rotation, only one connecting part is needed for the drive part of the output rod.

[0039] Although the present invention has been described with reference to preferred embodiments, those skilled in the art will understand that it is not limited to the description of the above embodiments, and various changes in form and detail may be made within the scope of the claims.
