Description

Technical Field

[0001] The utility model relates to the technical field of rotary drive components, and in particular to a drive device, a central control screen assembly and a vehicle. Background Art

[0002] With the rapid development of new energy vehicles, the central control screen has become a key component in the vehicle, serving as a hub for information display, input operations, and entertainment interaction. To facilitate viewing for front-seat passengers, the screen must be able to adjust its horizontal and vertical tilt angles for a comfortable viewing angle.

[0003] Conventional technology uses parallel push rods and ball joints to drive the central control screen's rotation. Specifically, the upper portion of the central control screen is hinged with two independent, parallel linear mechanisms, while the lower portion is equipped with a ball joint structure. When the two linear mechanisms extend and retract synchronously with the same amplitude, the central control screen's pitch angle can be adjusted. When the two linear mechanisms extend and retract at different amplitudes, the central control screen's horizontal angle can be adjusted. This achieves two degrees of freedom in the central control screen's angle adjustment.

[0004] In the above structure, the theoretical travel boundary of the parallel push rod and ball joint structure is an irregular shape, while the required travel boundary of the central control screen is usually rectangular, circular, etc. To ensure that the central control screen can rotate to any position within the required travel boundary, the theoretical travel boundary needs to be larger than and included in the required travel boundary. This allows the central control screen to move within a larger range (theoretical travel boundary), which easily infringes on the passenger's activity space.

[0005] The existing technology typically uses electronic control to solve this problem, specifically to ensure the telescopic accuracy of the linear mechanism, so that the central control screen moves only within the required travel range. However, due to limitations in installation and control precision, it is difficult to ensure that the central control screen moves precisely within the required travel range. Furthermore, when the central control screen is stationary, it still has a wider range of movement (i.e., within the theoretical travel range), but the linear mechanism cannot withstand large external forces. If a passenger or other object touches the central control screen, the central control screen may still move outside the required travel range. Utility Model Content

[0032] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0033] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0035] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] like Figures 1 to 7 As shown, an embodiment of the driving device according to the present application includes a base 10, a mounting frame 20, a driving mechanism 30 and a limiting structure 40. The mounting frame 20 is movably connected to the base 10, and the mounting frame 20 is used to install the component to be driven. The driving mechanism 30 is arranged on the base 10 and connected to the mounting frame 20. The driving mechanism 30 is used to drive the mounting frame 20 to move relative to the base 10 within the theoretical stroke boundary range A1, and the driving mechanism 30 includes at least one driving rod, which is hinged to the mounting frame 20 and has a linear driving function. The limiting structure 40 is arranged between the base 10 and the mounting frame 20. The limiting structure 40 is used to limit the movement of the mounting frame 20 to the target stroke boundary range A2. Furthermore, the theoretical stroke boundary range A1 is larger than the target stroke boundary range A2, and the theoretical stroke boundary range A1 at least includes the target stroke boundary range A2.

[0037] In the technical solution of this embodiment, the drive mechanism is capable of driving the base to move relative to the mounting bracket within a first range. During movement, the mounting bracket's range of motion is limited to the target travel boundary by a limiting structure. Therefore, during movement, the limiting structure ensures that the mounting bracket's range of motion does not exceed the target travel boundary, meaning that the mounting bracket's range of motion does not encroach on additional space. Furthermore, by ensuring that the theoretical travel boundary at least includes the target travel boundary, the mounting bracket is able to move to any point within the theoretical travel boundary. Therefore, the technical solution of this embodiment addresses the drawback of prior art vehicles' central control screens, which have a large movable range and are prone to encroaching on passenger space.

[0038] First, it should be noted that the drive device of this embodiment can be used in any mechanical structure requiring movement in various fields. Specifically, the component to be driven can be mounted on the mounting bracket 20. For ease of explanation, the following example uses the drive device of this embodiment to control the movement of a central control screen in an automobile. However, the following should not be construed as limiting the application of the drive device of this embodiment to the central control screen in an automobile.

[0039] It should be further explained that the above-mentioned mounting bracket 20 is movably mounted on the base 10, and the "movement" can be planar movement, rotation around a certain rotation axis, rotation around a certain point (ball joint, universal joint, etc.), or irregular movement.

[0040] Specifically, the driving device in this embodiment is used to control the position of the central control screen of the car, that is, to install the central control screen body on the mounting frame 20.

[0041] It should be further explained that the above-mentioned theoretical travel boundary range A1 is the movement range of the mounting frame 20 before being limited by the limiting structure 40, and the above-mentioned target travel boundary A2 is the movement range of the mounting frame 20 after being limited by the limiting structure 40.

[0042] Furthermore, the drive rod of the drive mechanism 30 can drive the mounting frame 20 to move in two degrees of freedom: swinging about two mutually perpendicular axes, thereby corresponding to the horizontal and vertical angle adjustment of the central control screen within the vehicle. Of course, the drive rod of the drive mechanism 30 can also drive the mounting frame 20 to move in other ways.

[0043] Figure 7 In the content shown, the horizontal axis represents the horizontal angle, in degrees, and the vertical axis represents the pitch angle, in degrees. Furthermore, the theoretical travel boundary range A1 is the area enclosed by the two outermost irregular curves and the two vertical lines, which represents the theoretical travel boundary range that the drive mechanism 30 can reach by driving the mounting frame 20, that is, the range of motion of the mounting frame 20 before it is limited by the limiting structure 40. The target travel boundary range A2 is the area enclosed by the middle square, which represents the target travel boundary range of the mounting frame 20, that is, the range of motion of the mounting frame 20 after being limited by the limiting structure 40. The target travel boundary range A2 is designed according to the use environment and actual needs of the central control screen. For example, the shape of the target travel boundary range A2 can be square, circular, irregular, etc.

[0044] certainly, Figure 7The theoretical stroke boundary range A1 and target stroke boundary range A2 shown are for illustration only. Those skilled in the art will determine the specific shape of the theoretical stroke boundary range A1 based on the specific form of the driving mechanism 30, and determine the shape of the target stroke boundary range A2 based on the actual movement requirements of the component to be driven. Figure 7 The content shown should not be understood as a limitation of the theoretical range limit range A1 and the target range limit range A2.

[0045] Furthermore, in order to enable the mounting bracket 20 to move to any point within the target travel boundary range A2, in this embodiment, the theoretical travel boundary range A1 is set to be larger than the target travel boundary range A2, and the theoretical travel boundary range A1 must at least include the target travel boundary range A2. For example, if the left and right swing angle design requirement of the central control screen is plus or minus 15°, the theoretical left and right swing angle that the driving mechanism 30 can drive the mounting bracket 20 to reach is plus or minus 20°. For another example, if the pitch swing angle design requirement of the central control screen is plus or minus 20°, the theoretical pitch swing angle that the driving mechanism 30 can drive the mounting bracket 20 to reach is plus or minus 25°. This arrangement can ensure that the central control screen can be moved to any point within the range of plus or minus 15° left and right and plus or minus 20° pitch.

[0046] from Figure 7 From the content shown, the graph of the theoretical travel boundary range A1 completely covers the target travel boundary range A2, so as to ensure that the mounting bracket 20 can be driven to move to any point in the theoretical travel boundary range A1.

[0047] As mentioned above, target travel boundary A2 is designed based on the specific usage requirements of the central control screen. In other words, moving the mounting bracket 20 to a position between target travel boundary A2 and theoretical travel boundary A1 (or, in other words, moving it outside target travel boundary A2) is useless and unnecessary. In fact, if the mounting bracket 20 moves outside target travel boundary A2, it will encroach on passenger space.

[0048] To this end, this embodiment further includes a limiting structure 40. This limiting structure 40 serves to restrict the movement of the mounting bracket 20 to within the theoretical travel boundary A1, or, more specifically, within the target travel boundary. In other words, when the mounting bracket 20 moves within the target travel boundary, the limiting structure 40 does not limit the mounting bracket 20. However, when the mounting bracket 20 reaches the target travel boundary, the limiting structure 40 does limit the mounting bracket 20, preventing further outward movement and preventing the central control screen from encroaching on passenger space.

[0049] like Figures 2 to 5As shown, in the technical solution of this embodiment, the limiting structure 40 includes a limiting groove 41 and a limiting protrusion 43. The limiting groove 41 is provided on one of the base 10 and the mounting frame 20 and has a limiting wall 42. The limiting protrusion 43 is provided on the other of the base 10 and the mounting frame 20 and is located within the limiting groove 41. Furthermore, when the mounting frame 20 moves to the boundary of the target travel range A2, the limiting protrusion 43 abuts against the limiting wall 42.

[0050] Specifically, the limiting wall 42 is a sidewall of the limiting groove 41 and is a complete wall extending along the circumferential direction. In this embodiment, the limiting groove 41 is provided on the mounting bracket 20, and the limiting protrusion 43 is provided on the base 10. When the mounting bracket 20 moves relative to the base 10, the limiting groove 41 moves relative to the limiting protrusion 43.

[0051] Of course, in some embodiments not shown, the setting positions of the limiting groove 41 and the limiting protrusion 43 can also be swapped, that is, the limiting groove 41 can be set on the base 10 and the limiting protrusion 43 can be set on the mounting frame 20.

[0052] Combine Figures 3 to 5 ,as well as Figure 7 It can be seen that the limiting protrusion 43 extends into the limiting groove 41. When the mounting frame 20 moves within the target travel boundary range (within the target travel boundary range A2), the limiting protrusion 43 does not contact the limiting wall 42, and the limiting structure 40 does not limit the mounting frame 20. When the mounting frame 20 moves to any boundary of the target travel (any boundary position of the target travel boundary range A2), the limiting protrusion 43 abuts the limiting wall 42, and the limiting structure 40 limits the mounting frame 20. At this point, the mounting frame 20 cannot move further outward, which means that the central control screen will not encroach on the passenger space.

[0053] And when the mounting bracket 20 moves to the target travel boundary range A2, even if the passenger presses the central control screen or other objects push the central control screen, the mounting bracket 20 cannot move outward because the limiting protrusion 43 is in contact with the limiting wall 42 at this time, so the central control screen will not move beyond the target travel boundary range A2.

[0054] Those skilled in the art will appreciate that the shape of the aforementioned limiting wall 42 represents the outer contour of the movement envelope of the limiting protrusion 43 relative to the limiting groove 41 when the mounting frame 20 moves within the target travel range A2 relative to the base 10. Therefore, the specific shape of the limiting wall 42 can be determined by those skilled in the art through software simulation or mathematical calculation based on the target travel range of the mounting frame 20 and the shape of the limiting protrusion 43.

[0055] like Figure 4 As shown, in the technical solution of this embodiment, the limiting wall 42 includes a first surface 421 and a second surface 422 that are relatively arranged, and a third surface 423 and a fourth surface 424 that are relatively arranged. The arrangement direction of the first surface 421 and the second surface 422 is perpendicular to the arrangement direction of the third surface 423 and the fourth surface 424.

[0056] Specifically, first surface 421, second surface 422, third surface 423, and fourth surface 424 form a substantially rectangular shape. When the drive device is installed in a vehicle, first surface 421 is the top, second surface 422 is the bottom, and one of third surface 423 and fourth surface 424 is the left side and the other is the right side.

[0057] Taking the third surface 423 as the left side and the fourth surface 424 as the right side as an example, the limiting methods of the above four surfaces are described below;

[0058] 1. When the mounting frame 20 swings downward and reaches the limit position (the lower edge of the target travel boundary range A2), the limiting protrusion 43 abuts against the first surface 421. At this time, if the left-right angle of the mounting frame 20 is adjusted, the limiting protrusion 43 slides on the first surface 421.

[0059] 2. When the mounting frame 20 swings upward and reaches the limit position (the upper edge of the target travel boundary range A2), the limiting protrusion 43 contacts the second surface 422. At this time, if the left-right angle of the mounting frame 20 is adjusted, the limiting protrusion 43 slides on the second surface 422.

[0060] 3. When the mounting frame 20 swings rightward and reaches the limit position (the right edge of the target travel boundary range A2), the limiting protrusion 43 contacts the third surface 423. At this time, if the vertical angle of the mounting frame 20 is adjusted, the limiting protrusion 43 slides on the third surface 423.

[0061] 4. When the mounting frame 20 swings leftward and reaches the limit position (the left edge of the target travel boundary range A2), the limiting protrusion 43 abuts against the fourth surface 424; at this time, if the vertical angle of the mounting frame 20 is adjusted, the limiting protrusion 43 slides on the fourth surface 424.

[0062] When designing, those skilled in the art may adjust the specific shapes of the edges of the graph of the target travel boundary range A2 according to actual conditions. Therefore, correspondingly,

[0063] The first surface 421 may be a straight surface, a curved surface or an irregular surface;

[0064] The second surface 422 may be a straight surface, a curved surface, or an irregular surface;

[0065] The third surface 423 may be a straight surface, a curved surface, or an irregular surface;

[0066] The fourth surface 424 may be a straight surface, a curved surface, or an irregular surface.

[0067] like Figure 4 As shown, in the technical solution of this embodiment, two adjacent surfaces among the first surface 421 , the second surface 422 , the third surface 423 and the fourth surface 424 are connected by an arc surface 425 .

[0068] Specifically, when the mounting bracket 20 moves relative to the base 10 to a corner position within the target travel range A2, the limiting protrusion 43 abuts against the arcuate surface 425. By providing an arcuate structure (arc-shaped surface 425) at the intersection of two adjacent surfaces among the first surface 421, the second surface 422, the third surface 423, and the fourth surface 424, the limiting protrusion 43 and the limiting groove 41 can better fit.

[0069] like Figure 5 As shown, in the technical solution of this embodiment, the limiting protrusion 43 is a conical structure. Specifically, the limiting protrusion 43 is a cone. Figure 3 and Figure 4 As can be seen, the limiting wall surface 42 corresponds to an inclined surface. In this way, when the limiting protrusion 43 extends into the limiting groove 41 and the mounting bracket 20 moves to the target stroke boundary range, the limiting protrusion 43 and the limiting wall surface 42 can fit together more closely.

[0070] In some embodiments not shown, the limiting protrusion 43 may also be a cylindrical or other structure.

[0071] like Figures 1 to 3 ,as well as Figure 5 As shown, in the technical solution of this embodiment, the base 10 includes a base body 11 and a connecting rod 12, the first end of the connecting rod 12 is hinged to the base body 11, the second end of the connecting rod 12 is connected to the mounting frame 20 through a ball joint structure 50, and the limiting structure 40 is arranged between the ball joint structure 50 and the mounting frame 20.

[0072] Specifically, when the mounting bracket 20 moves relative to the base 10, the connecting rod 12 swings relative to the base body 11, and the mounting bracket 20 rotates relative to the connecting rod 12 about the ball joint structure 50. Therefore, the limiting structure 40 is disposed between the ball joint structure 50 and the mounting bracket 20, enabling the limiting protrusion 43 to move within the limiting groove 41.

[0073] Specifically, from Figures 3 to 5As shown, in the technical solution of this embodiment, the ball joint structure 50 includes a ball head 51 and a rotating sleeve 52. The ball head 51 is mounted on the second end of the connecting rod 12, and the rotating sleeve 52 is mounted on the mounting bracket 20 and is mounted on the outside of the ball head 51. The limiting protrusion 43 is located on the side of the ball head 51 facing away from the connecting rod 12, and the limiting groove 41 is provided on the mounting bracket 20 and is located on the side of the rotating sleeve 52 facing away from the connecting rod 12.

[0074] Specifically, the ball head 51 is spherical and can rotate about the rotating sleeve 52, thereby enabling the mounting bracket 20 to rotate about the ball head. A stopper protrusion 43 is provided at the end of the ball head 51 and extends toward the stopper slot 41. After assembly, the stopper protrusion 43 extends into the stopper slot 41.

[0075] Combine Figure 3 Those skilled in the art will appreciate that when the mounting bracket 20 moves, it rotates around the ball head 51. Conversely, the ball head 51 can drive the limiting protrusion 43 to move within the limiting groove 41. When the mounting bracket 20 moves to the boundary of the target travel range A2, the limiting protrusion 43 abuts against the limiting wall 42, thereby preventing the mounting bracket 20 from further rotating outward around the ball head 51.

[0076] like Figure 3 As shown, in the technical solution of this embodiment, a mounting recess 21 is provided on the mounting frame 20, and the rotating sleeve 52 is disposed in the mounting recess 21. The limiting structure 40 further includes a limiting block 44, a limiting groove 41 is provided on the limiting block 44, and the limiting block 44 is disposed in the mounting recess 21, and the limiting block 44 is located on the side of the rotating sleeve 52 facing away from the connecting rod 12.

[0077] The following combination Figure 3 and Figure 6 The structures of the limiting block 44 and the rotating sleeve 52 are described in detail.

[0078] from Figure 3 and Figure 6 It can be seen that the limiting block 44 is assembled at the bottom position of the mounting recess 21 , and the limiting groove 41 is provided on the limiting block 44 , and the limiting groove 41 passes through two opposite surfaces of the limiting block 44 .

[0079] Furthermore, the stop block 44 is provided with a mating surface 45, which is configured to mate with the outer surface of the ball head 51. The mating surface 45 is located on the side of the stop wall 42 that faces the connecting rod 12. The mating surface 45 is specifically a spherical crown surface. During the rotation of the mounting bracket 20 relative to the ball head 51, the mating surface 45 ensures a stable gap between the stop block 44 and the ball head 51.

[0080] from Figure 3 and Figure 6It can be seen that the rotating sleeve 52 is arranged in the mounting recess 21 and is located outside the limit block 44 , and there is a gap between the rotating sleeve 52 and the limit block 44 , thereby ensuring that there is a gap between the ball head 51 and the limit block 44 .

[0081] Furthermore, the two rotating sleeves 52 are arranged opposite to each other, and the inner walls of the two rotating sleeves 52 are arc-shaped surfaces with opposite inclination directions. The inner walls of the two rotating sleeves 52 together form a spherical crown surface, and the two rotating sleeves 52 are easy to assemble from both sides of the ball head 51.

[0082] During assembly, first install the limit block 44 at the bottom of the mounting recess 21, then place a butterfly spring on the outside of the limit block 44; then, fit the rotating sleeve 52 over the ball head 51, insert the rotating sleeve 52 into the mounting recess 21, and tighten the butterfly spring; then, fit the limit plate into the limit groove outside the rotating sleeve 52. The butterfly spring and the limit plate together limit the position of the rotating sleeve 52, which also limits the position of the ball head 51. After assembly, the limit protrusion 43 extends into the limit groove 41.

[0083] like Figure 2 As shown, in the technical solution of this embodiment, the driving mechanism 30 includes two driving cylinders 31 arranged in parallel, and the push rods 311 of the driving cylinders 31 form the above-mentioned driving rod and are hinged to the mounting frame 20. The push rods 311 of the two driving cylinders 31 move independently.

[0084] Specifically, the driving cylinder 31 may be in the form of a lead screw nut, a linear motor, an electric push rod, an air cylinder, an oil cylinder, etc. The push rod 311 refers to the end of the push rod of the driving cylinder 31 .

[0085] Combine Figure 1 As shown, those skilled in the art will understand that when the push rods 311 of the two drive cylinders 31 extend and retract synchronously and the movement amounts are consistent, the vertical swing angle of the base 10 can be adjusted. When one push rod 311 of the two drive cylinders 31 extends and the other retracts, or when both push rods 311 extend but the extension lengths are inconsistent, or when both push rods 311 retract but the retraction lengths are inconsistent, the left and right swing angle of the base 10 can be adjusted.

[0086] The movement of the push rods 311 of the two drive cylinders 31 drives the base 10 to rotate about the ball head 51, causing the limiting protrusion 43 to move within the limiting groove 41. When the mounting frame 20 moves to the boundary of the target travel range A2, the limiting protrusion 43 abuts against the limiting wall 42, thereby preventing the mounting frame 20 from further rotating outward about the ball head 51.

[0087] The present application also provides a central control screen assembly. According to an embodiment of the central control screen assembly of the present application, the central control screen assembly includes a central control screen body and the above-mentioned driving device, and the central control screen body is connected to the mounting frame of the driving device.

[0088] The present application also provides a vehicle. According to an embodiment of the vehicle of the present application, the vehicle includes the above-mentioned drive device, or includes the above-mentioned control screen assembly.

[0089] Optionally, the vehicle is a new energy electric vehicle.

[0090] Furthermore, other structures in the vehicle that need to move, except for the central control screen, can adopt the above-mentioned driving device.

[0091] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
